Description

Technical Field

[0001] The invention belongs to the technical field of container manufacturing, and in particular relates to a plant fiber container manufacturing device, a manufacturing process and an advance heating process. Background Art

[0002] At present, in the production of container products, traditional equipment cannot realize automated mass production of paper-plastic cavity container products, cannot guarantee product qualification rate, has high labor intensity, low production efficiency, high energy loss, and large floor space. In addition, in its traditional process, its molding, cold pressing and hot pressing process flow cannot realize full automation and mass production functions. The specific problems are as follows:

[0003] During molding, traditional equipment mostly uses horizontal slurry absorption in the process of plant fiber molding slurry absorption, that is, the axis of the container mold is placed in the horizontal direction, and the plant fiber slurry is absorbed into the mold by adsorption. The filter structure in the mold filters out the water in the slurry, and the plant fiber is attached to the filter structure of the mold, thereby forming the prototype of the container product (i.e., wet embryo, generally referred to as wet embryo before the product is dried). Since the horizontal slurry absorption method separates the container from the slurry by horizontal lifting, this method will cause the upper part of the container to separate from the liquid surface first. At this time, this area can no longer absorb slurry, while the area below the liquid level will continue to absorb slurry, and the remaining slurry inside the container product will be discharged through the lower half of the container due to gravity. At the same time, the plant fiber will accumulate in the lower half of the container, resulting in uneven thickness of the upper and lower side walls of the container product. This phenomenon is commonly known as slurry pocketing.

[0004] For products with closed-end containers, when the slurry flows into the closed end, its flow rate is faster than the flow rate inside the container, resulting in relatively poor fiber adsorption effect at the closed end, and then problems such as unevenness and thin wall thickness occur.

[0005] During cold pressing or hot pressing, it is necessary to apply pressure to the inner wall of the product during the production process to increase the structural strength of the preformed product and remove excess moisture. Usually, an airbag is installed on the tooling that applies pressure to the product, and the inner wall of the product is extruded and shaped by inflation and deflation. The airbag is a consumable part with a short service life, high replacement frequency and high cost. When multiple airbags use the same air source at the same time, if an airbag deflates, it will cause insufficient pressure in other airbags. If the airbag bursts, it will easily affect the work of other airbags, thereby reducing the production quality of the product.

[0006] During hot pressing, when the prior art performs hot pressing and drying operations on container products, the hot pressing time is twice the molding time, so after the molding process is completed, it is necessary to wait for the products in the hot pressing process to be completed and transferred, and then the products in the molding process can enter the hot pressing station for heating, resulting in too much waiting time in the molding process and low overall system efficiency; in addition, in order to improve efficiency during hot pressing and drying, the prior art often uses robots to transfer products and cylinders to close the mold, resulting in large equipment footprint, low efficiency and high energy consumption; in addition, the traditional manual alignment adjustment method cannot improve the fine-tuning accuracy and efficiency, and reduce the labor intensity of personnel; in addition, in the traditional industry, the hot pressing platform is heated and the heat is transferred to the hot pressing mold, and the hot pressing mold dries the wet embryo when receiving it. Whether the mold can stably maintain the specified heat becomes the key point of drying efficiency. Since the humidity of wet embryo is generally 60%-80%, its water content is relatively high. When it contacts the hot pressing mold, the hot pressing mold will be cooled down. The lowered temperature is then transmitted to the temperature measuring device through the mold. The temperature control system then performs a heating operation. The temperature is then transmitted to the hot pressing mold through the hot pressing platform. This process is extremely time-consuming. If the product quality requirements are to be met, the time needs to be extended, which seriously reduces the work efficiency; if the heating time is fixed, the product may not be completely dried, reducing the product quality.

After reaching the predetermined position, the slurry suction component descends, and the cold pressing expansion body extends into the molding cavity along the cavity opening.

[0098] When the wet embryo is completely dried, the dry embryo is obtained.

[0099] Another object of the present invention is to propose a hot pressing advance heating process to solve the problems of slow heating, time waste, reduced work efficiency and the inability of the mold to stabilize within the required temperature range in the existing hot pressing process.

[0100] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0101] A hot pressing advance heating process is used in the process of heating and drying the wet embryo produced by the pulp molding process: including:

[0102] Before and / or after receiving the wet embryo, start the heating device to heat the hot pressing lower mold and / or the hot pressing upper mold so that the temperature thereof is not less than the working temperature and store heat energy;

The temperature extremes are used to set the maximum temperature of the hot pressing lower mold and / or the hot pressing upper mold during the advance heating period, and the heating power is used to adjust the heating rate during the advance heating period.

[0106] Compared with the prior art, the plant fiber container manufacturing device, manufacturing process and advance heating process described in the present invention have the following advantages:

[0107] (1) The plant fiber container manufacturing device, manufacturing process and advance heating process described in the present invention adopt a vertical slurry suction operation, so that the cavity mouth of the molding cavity is finally separated from the slurry pool liquid surface, so that the slurry suction time at the closing of the container product is increased, thereby increasing the fiber layer thickness at the closing of the container product, effectively solving the problem of thin and uneven thickness at the closing; at the same time, due to the vertical slurry suction method, when the molding cavity is separated from the liquid surface, the excess slurry is discharged from the cavity mouth of the molding cavity, solving the problem of horizontal slurry suction in traditional equipment, ensuring the uniformity of product wall thickness, and improving the product qualification rate of container products;

[0108] By controlling the slurry flow and pressure in the cavity, the molding operation of the container product (forming a wet embryo) can be achieved, which can meet the requirements of the product's wall thickness, strength, density, etc. When there are multiple cavities, the wall thickness, strength, density, etc. requirements of the specified area can be met, thereby ensuring the consistency of the product, improving the product qualification rate of the container product, and greatly meeting the market demand.

[0109] (2) The plant fiber container manufacturing device, manufacturing process and advance heating process described in the present invention utilize the form of inflating and deflating the expansion body (filling / extracting recyclables) and the shrinkable characteristics of the expansion body, so that the cold / hot expansion body can be stored in the guide column, ensuring that the cold / hot expansion body can smoothly enter or leave the product. Therefore, while increasing the diameter of the expansion body, the scratches of the expansion body can be reduced. Since the expansion body with an increased diameter is used for work, the expansion ratio is reduced, and the service life of the expansion body can be increased;

[0110] A one-way speed regulating valve is set as an explosion-proof structure of the expansion body. When an expansion body ruptures, the one-way speed regulating valve makes the flow rate of the filler passing through the damaged part much lower than the total flow rate of the filler when entering the rectifier box, so it will not cause too much impact on other expansion bodies, thereby ensuring that the remaining products can be produced normally.

[0111] (3) The plant fiber container manufacturing device, manufacturing process and advance heating process described in the present invention, the lateral movement power component drives the upper / lower hot pressing platform to receive the wet product with openings after forming and cold pressing, and can return to the original hot pressing station. The upper and lower hot pressing platforms realize the product mold closing processing through the mold closing power component. After the upper and lower hot pressing platforms are molded, the wet product is heated and air is sucked. At the same time, the expansion body enters the product and presses its inner wall to discharge excess moisture, thereby realizing hot pressing drying of the container product. The setting of this device can effectively realize the automatic hot pressing drying of the product and improve efficiency.

[0112] (4) The plant fiber container manufacturing device, manufacturing process and advance heating process described in the present invention, the lateral movement force component can realize the transfer of the processed products of the previous process. The specific structure adopts the method of using a servo motor to drive the nut screw to control the displacement of the upper / lower platform of the hot pressing. The moving distance has high accuracy. Compared with the traditional transfer method, it saves the floor space of the traditional manipulator transfer device and saves the space reserved for the traditional transfer device to enter the platform.

[0113] (5) The plant fiber container manufacturing device, manufacturing process and preheating process described in the present invention can realize the fine-tuning function of the lateral alignment of the upper and lower platforms of the hot pressing by using the lateral force component, because the lateral movement and the moving distance are precise; the fine-tuning function of the longitudinal alignment of the upper and lower platforms of the hot pressing can be realized by two parallel hot pressing adjustment bolts; compared with the traditional knocking alignment adjustment method, the device of the present patent can improve the fine-tuning accuracy and efficiency and reduce the labor intensity of personnel.

[0114] (6) The plant fiber container manufacturing device, manufacturing process and advance heating process described in the present invention, and the structural setting of the hot pressing and tensioning assembly can realize the pneumatic locking function, which reduces the labor intensity of personnel compared with the traditional manual locking method using screws; at the same time, it saves the operating space reserved inside the platform caused by the traditional manual locking method.

[0115] (7) The plant fiber container manufacturing device, manufacturing process and advance heating process described in the present invention, the combination of the lateral force component and the hot pressing tension component, further saves the reserved operating space of the upper and lower platforms of the hot pressing, thereby reducing the mold closing movement distance, improving the mold closing efficiency, and reducing energy loss. The overall effect of the hot pressing process: reducing the occupied space, reducing energy consumption through the compactness of the device, and improving efficiency.

[0116] (8) The present invention discloses a plant fiber container manufacturing device, manufacturing process and advance heating process. The structure of the mold closing power component adopts a motor to drive the nut screw to drive the support plate, so that the upper / lower platform of the hot pressing can be lifted and lowered for mold closing. When the mold is about to be closed, the moving platform speed is required to be relatively low, so a motor that can be precisely controlled is selected for control. This technology can realize high-speed movement except for the stage about to be closed, change the speed curve, and improve production efficiency. Because the motor cooperates with the screw structure to realize the precise control of the lifting height of the platform, it is avoided that the platform collides or generates gaps during mold closing, resulting in damage to the product or parts. Because the motor cooperates with the screw structure to realize the precise control of the lifting height of the platform, according to the different specifications of the processed products, the mold opening height of the hot pressing platform can be reduced as much as possible, the mold opening time can be reduced, and the production efficiency can be improved.

[0117] (9) The present invention discloses a plant fiber container manufacturing device, manufacturing process and advance heating process. In the prior art, when the container product is hot-pressed and dried, the hot-pressing time is twice the molding time, which results in the need to wait for the product in the hot-pressing station to be completed and transferred after the molding process is completed, and then the products in the molding and cold-pressing stations can enter the hot-pressing station for heating, resulting in too much waiting time in the molding process, reducing the floor space, and the overall system efficiency is low. Therefore, a method of processing with multiple hot-pressing stations is selected to improve the heating efficiency.

[0118] At least two hot pressing stations are arranged in series according to the process. The force component is moved laterally in the hot pressing station of the latter process to drive the hot pressing lower platform or the hot pressing upper platform inside it away from or close to the hot pressing upper platform or the hot pressing lower platform that has not moved in the hot pressing station of the previous process.

[0119] In the present invention, the lateral force components of the plurality of hot pressing stations all slide axially along the same first guide rail, so that the plurality of hot pressing upper and lower platforms can be more precisely adapted to the mold and the product quality is better.

[0120] The setting of multiple hot pressing stations not only improves production efficiency, but also further saves floor space and improves product quality.

[0121] (10) The plant fiber container manufacturing device, manufacturing process and pre-heating process described in the present invention, multiple hot pressing stations connected in series or a single hot pressing station that can complete the hot pressing process are all called hot pressing units. One or more hot pressing units can be set in this patent to adapt to different combinations of molding and hot pressing process times. In this embodiment, one molding and cold pressing station is matched with two hot pressing units (U-shaped), that is, two hot pressing stations in series are respectively set on both sides of the molding and cold pressing stations. The single cycle time of the molding and cold pressing process is 1 minute, and the process of one hot pressing station is 4 minutes. When the above combination exists, the whole equipment can complete the output of a batch of products in 1 minute, avoiding waste caused by waiting at the work station.

[0122] (11) The plant fiber container manufacturing device, manufacturing process and pre-heating process described in the present invention, in the traditional industry, the hot pressing platform is heated and the heat is transferred to the hot pressing mold, and the hot pressing mold receives the wet embryo and dries it. Whether the mold can stably maintain the working temperature becomes the key point of drying efficiency. Since the moisture content of the wet embryo is generally 60%-80%, the hot pressing mold at the working temperature will be cooled down when it contacts the hot pressing mold. The reduced temperature is then transferred to the temperature measuring device through the mold, and the temperature control system performs the heating operation again. The temperature is then transferred to the hot pressing mold through the hot pressing platform. This process is extremely time-consuming and seriously reduces work efficiency.

[0123] The present invention adopts the method of early heating to solve such problems. The program is set to start the heating device in advance before and / or after receiving the wet embryo, without waiting for the temperature probe to feedback that the mold temperature is lower than the set temperature, to heat the hot pressing lower mold and / or the hot pressing upper mold to make its temperature not less than the working temperature, and to store heat energy to counteract the cooling effect caused by the wet embryo, so that the mold is stabilized within the required temperature range, thereby avoiding problems such as product quality and production efficiency caused by mold cooling.

[0185] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0186] like Figures 1 to 41 As shown, a plant fiber container manufacturing device includes a molding and cold pressing station and a hot pressing station. The controller is a conventional technical means well known to those skilled in the art, and the present invention does not improve it. The controller can be an existing industrial computer or PLC, and the model of the controller can be Advantech series.

[0187] See also Figure 1 and Figure 2 As shown, in the first aspect, this embodiment provides a forming and cold pressing station, and the forming and cold pressing station includes:

[0188] Slurry pool 1, frame assembly 2, transplanting mechanism 3, slurry suction component and cold pressing component 13;

[0189] The transplanting mechanism 3 is arranged on the frame assembly 2;

[0190] The slurry suction assembly has a built-in molding cavity 421;

[0191] The slurry suction component and the liquid surface of the first slurry groove 101 of the slurry pool 1 are moved relative to each other by the transplanting mechanism 3, and the slurry suction component penetrates into the liquid surface of the first slurry groove 101, and the slurry in the first slurry groove 101 enters the molding cavity 421 through the cavity opening of the molding cavity to perform the slurry suction operation. After the slurry suction operation is completed, the cavity opening of the molding cavity 421 faces downward, and the slurry suction component is away from the liquid surface of the first slurry groove 101, and the wet embryo preforming work is completed to form a preformed wet embryo;

[0192] The cold pressing assembly 13 includes a first extrusion unit, which is used to extrude the inner wall of the preformed wet embryo in the molding cavity 421 to form a wet embryo.

[0193] In a preferred embodiment of the present invention, the first extrusion unit includes a cold-pressed expansion body 134, which can enter the molding cavity 421 along the cavity opening, and the cold-pressed expansion body 134 is filled with recyclable objects to expand the cold-pressed expansion body 134, so as to extrude the inner wall of the preformed wet embryo in the molding cavity 421 to form a wet embryo;

[0194] The hot pressing station includes a hot pressing lower platform 17 and a hot pressing upper platform 18. The hot pressing lower platform 17 or the hot pressing upper platform 18 receives the wet embryo. The clamping power component 16 provides power for the opening and closing of the hot pressing lower platform 17 and the hot pressing upper platform 18. The clamping of the hot pressing lower platform 17 and the hot pressing upper platform 18 is used to hot press the wet embryo. The hot pressing station also includes a second extrusion unit, and the second extrusion unit can approach and move away from the hot pressing upper platform 18 and the hot pressing lower platform 17. The second extrusion unit can enter the wet embryo and extrude its inner wall.

[0195] In a preferred embodiment of the present invention, the second extrusion unit is a part of the hot-pressing expansion assembly 22, and the second extrusion unit has the same structure as the first extrusion unit. Specifically, the second extrusion unit includes a hot-pressing expansion body 2212 and a hot-pressing guide column 2211;

[0196] The hot-pressing expansion body 2212 is sleeved on the periphery of the hot-pressing guide column 2211, and the hot-pressing guide column 2211 is a supporting structure of the hot-pressing expansion body 2212. The hot-pressing guide column 2211 is provided with a hot-pressing airflow channel 2213. The equipment for filling recyclable objects fills the hot-pressing expansion body 2212 with recyclable objects through the hot-pressing airflow channel 2213, and the equipment for extracting recyclable objects extracts the recyclable objects into the hot-pressing expansion body 2212 through the hot-pressing airflow channel 2213, so that negative pressure is formed in the hot-pressing airflow channel 2213, and the hot-pressing expansion body 2212 is stored in the hot-pressing airflow channel 2213;

[0197] The second extrusion unit also includes a hot pressing rectifier box 2214, the interior of the hot pressing rectifier box 2214 is a hollow chamber, the filling end of each hot pressing expansion body 2212 is connected to the hollow chamber of the hot pressing rectifier box 2214, and an air inlet nozzle and an air outlet nozzle are respectively arranged on the hollow chamber, the air inlet nozzle is externally connected to a device for filling recyclable objects, and the air outlet nozzle is externally connected to a device for extracting recyclable objects or to the air, and the device for filling recyclable objects expands the hot pressing expansion body 2212, thereby extruding the inner wall of the preformed wet embryo;

[0198] A hot-pressing one-way speed regulating valve 2215 is installed at the filling end of the hot-pressing expansion body 2212, and the hot-pressing one-way speed regulating valve 2215 is used to control the filling speed of the hot-pressing expansion body 2212 with recyclable objects.

[0199] Specifically, in the present embodiment, the controller controls the transplanting mechanism 3 provided on the frame assembly 2, thereby controlling the servo motor driving the transplanting mechanism 3 to work, and the vertically arranged chain transmission drives the mechanical arm 31 to rise and fall and move left and right, and the transplanting mechanism 3 drives the slurry suction component to vertically penetrate into or away from the liquid surface of the first slurry groove 101 of the slurry pool 1. At the same time, through the cooperation of the external control device, the slurry suction operation of the slurry suction component is carried out, and the flow rate and pressure in the slurry suction component are controlled to complete the preforming work of the wet embryo of the molded product; the transplanting mechanism 3 drives the slurry suction component to enter the cold pressing station, and the cold pressing expansion body 134 provided in the cold pressing component 13 is used. The cold pressing expansion body 134 enters the molding cavity 421 along the cavity mouth, and the cold pressing guide column 131 can be used to fill the recyclable objects into the cold pressing expansion body 134 to expand the cold pressing expansion body 134, so as to extrude the inner wall of the preformed wet embryo in the molding cavity 421, discharge the excess water, and finally process the wet embryo.

[0200] In addition, the transplanting mechanism 3 can also be connected to the pulp pool 1 to drive the pulp pool 1 to move up and down, so that the pulp suction component can go deeper into or farther away from the liquid surface of the first pulp tank 101.

[0201] The frame assembly 2 here can be a structure such as a wall, a frame, etc., as long as it is a device that can install the transplanting mechanism 3.

[0202] It should be noted that the transplanting mechanism 3 of this embodiment is a conventional technical means well known to those skilled in the art, and will not be further described here.

[0203] In a preferred embodiment of the present invention, Fig.11 , Fig.16 and Fig.17 As shown, in this embodiment, the cold-pressed expansion body 134 is an air bag, such as Fig.11 As shown, the cold-pressed guide pin 131 is a supporting structure of the airbag, and the cold-pressed guide pin 131 is connected to an external inflation device (device for filling recyclable objects) and / or an exhaust device (device for extracting recyclable objects) through an air pipe to achieve the expansion or contraction of the airbag. The inflation device can fill the recyclable objects into the airbag through the cold-pressed guide pin 131, and the recyclable objects are media such as gas, liquid, high-temperature gas, and high-temperature liquid, so as to expand the airbag, and the expanded airbag is used to extrude the inner wall of the preformed wet embryo.

[0204] The outer diameter of the airbag may be smaller than the diameter of the product opening in the natural state, or smaller than the diameter of the container opening in the vacuum contraction state, and may also include the coordination of the airbag and container opening diameters in other states, as long as the airbag can enter the interior of the container.

[0205] The forming and cold pressing stations of this embodiment control the slurry suction component to vertically penetrate into or move away from the liquid surface of the first slurry tank 101 through the transplanting mechanism 3. The cavity opening of the forming cavity 421 is arranged toward the liquid surface of the first slurry tank 101. When the slurry suction component leaves the liquid surface of the first slurry tank 101, excess slurry will flow out through the cavity opening.

[0206] By controlling the internal flow and pressure of the slurry suction component, the vacuum degree in the molding cavity 421 can be controlled to adjust the state of slurry suction or dehydration. By vacuuming, the plant fibers are attached to the molding cavity 421 of the slurry suction component and dehydration is completed, thereby realizing the preforming of the wet embryo and forming a preformed wet embryo. The slurry suction component is then controlled by the transplanting mechanism 3 to be transplanted to the cold pressing station (i.e., the second slurry tank 102), and the cold pressing expansion body 134 provided in the cold pressing component 13 is used to extrude the inner wall of the preformed wet embryo in the molding cavity 421 to discharge excess water and obtain a wet embryo.

[0207] This embodiment adopts the form of vertical slurry suction operation, so that the cavity mouth of the molding cavity 421 is finally separated from the liquid surface of the first slurry tank 101, so that the slurry suction time at the closing end of the container product is increased, thereby increasing the thickness of the fiber layer at the closing end of the container product, and effectively solving the problem of thin and uneven thickness at the closing end; at the same time, due to the vertical slurry suction method, when the molding cavity 421 is separated from the liquid surface, the excess slurry is discharged from the cavity mouth of the molding cavity 421, which solves the problem of uneven wall thickness and damage of the container product caused by horizontal slurry suction in traditional equipment, and ensures that the wall thickness of the container product is uniform. The vertical slurry suction operation form here is not limited to the cavity mouth being 90 degrees to the liquid surface, but can also be other angles, as long as it is ensured that the excess slurry is discharged from the cavity mouth when it is separated from the liquid surface.

[0208] This embodiment adopts the form of inflating and deflating the airbag, and utilizes the expansion of the airbag to squeeze the inner wall of the wet embryo product in the molding cavity 421 to discharge excess water and increase the structural strength of the wet embryo product.

[0209] The wet embryo forming and cold pressing station of the molded product in this embodiment realizes the processing and forming of the pre-formed wet embryo by adopting the cold pressing operation mode of vertical slurry suction operation and inflation expansion of the cold pressing expansion body 134, which effectively improves the product quality and product qualification rate of the wet embryo processing and greatly meets the market demand.

[0210] In a preferred embodiment of the present invention, Figures 3 to 7 As shown, the slurry suction assembly includes a plurality of molding mold components 4, and the plurality of molding mold components 4 cooperate to form a molding cavity 421. The molding mold components 4 are connected to the mechanical arm 31 of the transplanting mechanism 3, and the mechanical arm 31 controls the opening and closing actions of the molding mold components 4. When the product to be processed is a closed-end container, it is necessary to use a plurality of molding mold components 4 to cooperate to form the molding cavity 421. Also due to the characteristics of closed-end container products, the slurry absorption problem is more likely to occur.

[0211] Specifically, the slurry suction assembly of this embodiment is provided with a plurality of molding mold components 4, and the plurality of molding mold components 4 cooperate with each other to form a molding cavity 421, and the molding mold components 4 are connected to the mechanical arm 31 of the transplanting mechanism 3. By controlling the movement of the mechanical arm 31, the opening and closing movements of the molding mold components 4 are completed, thereby realizing the slurry suction operation of the plant fiber pulp.

[0212] It should be noted that this embodiment is explained by taking two molding mold components 4 as an example. In addition to this embodiment, it is also applicable to the slurry suction assembly composed of three or more molding mold components 4 on the market, that is, several molding mold components 4 cooperate to form a molding cavity 421, which will not be further elaborated here.

[0217] Specifically, the front end mold 42 of this embodiment is provided with a molding cavity 421, which is connected to a cavity 431 provided on the back plate 43 of the molding mold. The cavity 431 is connected to an external device through a connecting pipe. By controlling the external device, the plant fibers in the plant fiber slurry sucked into the molding cavity 421 are attached to the filtering structure in the molding cavity 421, and the remaining liquid enters the cavity 431 through the filtering structure and is discharged through the connecting pipe, thereby realizing the pulp suction operation.

[0218] The front end mold 42 is connected to the molding mold back plate 43 through the molding component 41, and the molding component 41 adopts a structure that can quickly adapt to different forms of the front end molds 42 to improve flexibility.

In this embodiment, the first flow through hole 413 and the second flow through hole 414 both include a plurality of third flow through holes arranged along the first direction, and a first gap is reserved between adjacent third flow through holes; and;

[0224] a plurality of fourth flow passage holes arranged along the second direction, with second gaps reserved between adjacent fourth flow passage holes;

[0225] The fourth flow-through hole is located below the third flow-through hole.

[0226] It should be noted that the first direction of this embodiment is the vertical direction, and a plurality of third flow through holes are vertically arranged on the mold substrate 411 and the mold pad 412, and the third flow through holes are arranged at intervals. The second direction of this embodiment is the horizontal direction, and a plurality of fourth flow through holes are correspondingly arranged below the third flow through holes.

[0227] In this embodiment, a bottle-shaped container product is taken as an example, which can be extended to a closed container with an opening. The third flow through hole corresponds to the upper half of the bottle-shaped container product, and the fourth flow through hole corresponds to the lower half of the bottle-shaped container product. The third flow through hole and the fourth flow through hole can ensure the circulation of the slurry in the upper and lower parts of the entire bottle-shaped container product. The two flow through holes are arranged mainly to correspond to the shape of the processed product. In this embodiment, the bottle-shaped container product is divided into a bottle body and a bottle mouth, and the required flow rate or flow rate is different for consideration.

[0228] It should be noted that the present embodiment does not impose any specific restrictions on the specific circulation area or the number of mold pads 412. The number and size of the mold pads 412 of the present embodiment can be flexibly selected according to the actual site conditions to meet the needs of container products with different structures, and has strong adaptability.

[0229] Compared with the traditional operation that requires replacement of the mold base plate 411, the mold pad 412 in this embodiment can be replaced according to different types of container products. The number and size of the mold pad 412 can be flexibly selected according to the actual on-site conditions (mainly the shape of the product to be processed). The replacement cost is low, which can effectively save production costs. Moreover, each time a replacement is made, only the mold pad 412 needs to be replaced. The replacement is simple and easy to operate, and the space utilization is small, which effectively saves storage space.

The front end mold 42 and the mold pad 412 are fixed to the mold substrate 411 together by fasteners. It should be noted that the fasteners of the present embodiment can be fixed in the form of fastening screws or fastening bolts, so as to fix the front end mold 42 and the mold pad 412 on the mold substrate 411.

[0233] It should be noted that, in the prior art, for the setting position of the internal fixing hole 415, the technical means usually adopted is to open the internal fixing hole 415 at the corresponding position according to the installation position of the mold, while in the present embodiment, the internal fixing holes 415 at all positions are reserved on the mold substrate 411, and the fixed positions are selected based on the actual situation on site. In order to adapt to container products of different structural types and to facilitate the disassembly and replacement of mold pads 412 of different sizes, all the internal fixing holes 415 are reserved. This is also related to the detachable connection between the mold pad 412 and the mold substrate 411 for easy replacement. If it is not this type of mold plate structure, the function of reserving all the internal fixing holes 415 cannot be achieved.

[0234] In a preferred embodiment of the present invention, Fig. 9 As shown, a positioning hole 417 is provided on the mold base plate 411, and a positioning pin for positioning the front end mold 42 provided at the front end of the mold plate is arranged in the positioning hole 417.

[0235] Specifically, in order to facilitate the positioning and fixation of the front-end mold 42, the mold pad 412 and the mold substrate 411, the positioning hole 417 set on the mold substrate 411 is utilized, and the positioning pin is inserted into the positioning hole 417 to realize the positioning and fixation of the front-end mold 42, the mold pad 412 and the mold substrate 411. The positioning pin of this embodiment is not shown in the accompanying drawings.

At the same time, a handle 4110 is provided at one end of the mold substrate 411 to facilitate operators to pull the mold substrate 411 and realize the disassembly and assembly of the mold substrate 411. It should be noted that this embodiment does not specifically limit the number of positioning blocks 419, and it is sufficient to be able to position the mold substrate 411.

[0241] In a preferred embodiment of the present invention, Figure 6 and Figure 7 As shown, one end of the molding die back plate 43 is provided with a limiting block 4111 corresponding to the positioning block 419 at the end away from the handle 4110;

[0242] The other end of the molding die back plate 43 is provided with a positioning locking member 4112 corresponding to the positioning block 419 near the end of the handle 4110;

[0243] Specifically, guide grooves are provided on both sides of the molding mold back plate 43 to provide a pulling channel for the mold plate, which can improve the work efficiency of replacing the mold plate. A limit block 4111 is provided at one end of the molding mold back plate 43. The limit block 4111 is provided with a notch corresponding to the positioning block 419. After the mold substrate 411 is positioned, the positioning block 419 and the limit block 4111 are exactly corresponding and snapped together. At the same time, the positioning locking piece 4112 provided on the molding mold back plate 43 is used to lock the positioning block 419 set near the handle 4110 end to ensure repeated installation and positioning requirements.

[0244] It should be noted that the positioning locking member 4112 of this embodiment adopts a cam-type locking structure. The position of the cam is adjusted by rotating the handshake, and the cam is used to tighten the positioning block 419 to achieve position limiting on one side of the mold substrate 411. At the same time, it cooperates with the limit block 4111 set at the other end to achieve the positioning and locking installation of the mold substrate 411.

[0245] In a preferred embodiment of the present invention, Figures 3 to 7 As shown, the locking mechanism 5 includes a locking unit 51 and a locking rod 52;

[0246] The locking unit 51 is arranged on the molding die back plate 43, and drives the locking rod 52 to release or compress the elastic member in the locking unit 51, so that the locking block 516 in the locking unit 51 is actuated, causing the molding assembly 41 and the molding die back plate 43 to be locked or disengaged.

[0247] In a preferred embodiment of the present invention, Fig.10 As shown, the locking unit 51 includes a mounting block 511 disposed on the back plate 43 of the forming mold, a receiving cavity is disposed in the mounting block 511, the elastic member is disposed in the receiving cavity through a fixing block 515, and the locking pull rod 52 is disposed through the mounting block 511;

[0248] The elastic member includes a connecting column 512, one end of which is provided with an arc-shaped contact 513, and an elastic compression member 514 is sleeved on the connecting column 512, one end of the elastic compression member 514 abuts against the contact 513, and the other end of the elastic compression member 514 abuts against the fixing block 515, and the connecting column 512 extends outside the fixing block 515 and is fixedly connected to the locking block 516;

[0249] The locking rod 52 is provided with a plurality of slots 53 , the bottom end surface of the slots 53 is an inclined surface, and the contact 513 abuts against the inclined surface, driving the locking rod 52 to squeeze or release the contact 513 .

[0250] Specifically, the locking rod 52 is located in the initial position, and the contact 513 is located at the deepest part of the groove 53. At this time, the locking rod 52 does not generate an extrusion pressure on the contact 513. At this time, the locking block 516 is in a fallen state, causing the molding component 41 and the molding mold back plate 43 to separate; the locking rod 52 is pulled or rotated, and the contact 513 moves along the direction of the groove 53 opened on the locking rod 52. Since the bottom end face of the groove 53 is an inclined surface, the outer surface of the locking rod 52 will continuously apply an extrusion pressure to the contact 513 to make the contact 513 move; at the same time, under the action of the elastic compression member 514, the locking block 516 is lifted, causing the molding component 41 and the molding mold back plate 43 to be locked.

[0251] It should be noted that the elastic compression member 514 of this embodiment is in the form of a cold pressure spring 1313, which is sleeved on the connecting column 512, and the elastic force of the cold pressure spring 1313 itself is utilized to realize the action of the locking block 516.

[0252] In this embodiment, a locking mechanism 5 is provided on the back plate 43 of the molding mold, and the locking unit 51 and the locking rod 52 provided on the locking mechanism 5 are used to cooperate to quickly position the molding component 41. The locking mechanism 5 is actuated to achieve the purpose of quickly locking the molding component 41. It is estimated to take 1 minute, which solves the problem that the traditional industry mold installation and locking requires the use of multiple pressure plates and screws for locking, and each time the alignment is adjusted, the screws need to be removed and manually adjusted multiple times before re-locking, which is time-consuming and labor-intensive. It is estimated to take 45-90 minutes. Compared with the traditional mold installation and locking, this embodiment greatly shortens the locking time and effectively improves the work efficiency of the staff.

[0253] In a preferred embodiment of the present invention, Figures 1 to 7 As shown, the through hole 432 is connected to the air compressor device through the air compressor pipe 6 and the vacuum device through the vacuum pipe 7; and\or, the through hole 432 is connected to the external atmospheric pressure;

[0254] The slurry suction component is also provided with a detection unit and an adjustment unit, which cooperate with the adjustment unit to control the flow and / or pressure inside the cavity 431 to complete the slurry suction process and form a preformed wet embryo.

[0255] Specifically, this embodiment connects the cavity 431 to an external vacuum device through a vacuum pipe 7 and to an external air compressor device through an air compressor pipe 6, and at the same time, uses the detection unit and the adjustment unit to control the flow and / or pressure inside the cavity 431. When the container product is formed, the present application can meet the requirements of the wall thickness, strength, density, etc. of the product. When there are multiple cavities, the requirements of the wall thickness, strength, density, etc. of the specified area can be met. Compared with traditional paper-molding equipment, when the pressure and flow rate in the molding process fluctuate, the flow rate and pressure in the molding process can be detected and adjusted in real time, thereby ensuring the consistency of the product, improving the product qualification rate of the container product, and greatly meeting the market demand.

[0256] In a preferred embodiment of the present invention, the vacuum pipe 7 and the compressed air pipe 6 are provided with a switch valve 8 for controlling the switch of the pipes;

[0257] The vacuum pipe 7 and / or the compressed air pipe 6 is provided with a regulating valve 9 for controlling the flow rate of the pipe;

[0258] In response to the switch valve 8 and the regulating valve 9 being arranged on the same pipeline, the switch valve 8 and the regulating valve 9 are connected in series.

[0259] In response to the switch valve 8 and the regulating valve 9 being arranged on the same pipeline, the switch valve 8 and the regulating valve 9 are connected in series, and the opening of the regulating valve 9 can be adjusted before or during the wet embryo molding.

[0260] In a preferred embodiment of the present invention, a pressure control valve 11 is provided on the cavity 431, the vacuum pipe 7 or the air pressure pipe 6 to adjust the pressure in the cavity 431;

[0261] The cavity 431 is provided with a pressure detection unit 12 for detecting the pressure in the cavity.

[0262] Specifically, by setting a pressure control valve 11 on the cavity 431, the vacuum pipe 7, and the air pressure pipe 6, the valve body switch and the switch amount are controlled to control the internal pressure of the cavity 431. In addition, a pressure regulating pipe 10 can be connected to the cavity 431, the vacuum pipe 7, or the air pressure pipe 6, and a pressure control valve 11 can be set on the pressure regulating pipe 10, so as to realize the control of the internal pressure of the cavity 431.

[0263] In this embodiment, the pressure regulating pipe 10 is integrated with the rotating shaft of the robot arm, and the interior of the rotating shaft is hollow to serve as the pressure regulating pipe 10 .

[0264] In order to realize real-time monitoring of the internal pressure of the cavity 431, this embodiment is provided with a pressure detection unit 12 on the cavity 431. The pressure detection value of the pressure detection unit 12 reflects the internal pressure of the cavity, so that the flow or pressure of each pipeline can be adjusted according to the pressure detection value.

[0265] It should be noted that the pressure detection unit 12 of this embodiment adopts a pressure detection sensor, and utilizes the sensitive characteristics of the pressure detection sensor to realize pressure detection in the cavity 431.

[0266] In a preferred embodiment of the present invention, a plurality of cavities 431 are provided in the slurry suction assembly, and the internal gases or liquids of the plurality of cavities 431 are not connected to each other.

[0267] Specifically, in order to ensure the molding of plant fibers, the internal gases or liquids of the multiple cavities 431 are kept disconnected from each other in this embodiment, and each cavity 431 corresponds to a different plant fiber molding part. Each cavity 431 is independently controlled to better meet the requirements of wall thickness, strength, and density in different areas of plant fiber molding.

[0268] This embodiment is explained by taking the upper cavity 431 and the lower cavity 431 as examples. The upper cavity 431 corresponds to the bottle body and the bottom of the container product, and the lower cavity 431 corresponds to the bottle neck and the bottle mouth of the container product. The upper cavity 431 and the lower cavity 431 are respectively connected to the external vacuum equipment through their own independent vacuum pipes 7 groups, so that a negative pressure environment is formed between the upper cavity 431 and the lower cavity 431 to achieve the suction operation of the slurry. The upper cavity 431 and the lower cavity 431 are connected to the external air compressor equipment through independent air compressor pipes 6 groups, so that a positive pressure environment is formed between the upper cavity 431 and the lower cavity 431 to achieve the stripping operation of the molded product.

[0269] It should be noted that this embodiment adopts a method of independently controlling and detecting the upper and lower cavities 431. The lower cavity 431 is responsible for controlling the flow rate and pressure of peeling and slurry suction at the container closing (bottle mouth), and the upper cavity 431 is responsible for controlling the flow rate and pressure of peeling and slurry suction at the rest of the container (bottle body, bottle bottom).

[0270] In a preferred embodiment of the present invention, Fig.14 and Fig.15 As shown, the cold pressing assembly 13 is arranged in the second slurry groove 102 of the slurry pool 1; the first extrusion unit of the cold pressing assembly 13 also includes a cold pressing guide column 131, and the cold pressing expansion body 134 is sleeved on the outer periphery of the cold pressing guide column 131, and the cold pressing guide column 131 is a supporting structure of the cold pressing expansion body 134, and the cold pressing guide column 131 is used to support the cold pressing expansion body 134, so that the cold pressing expansion body 134 has a certain stiffness, thereby ensuring that the cold pressing expansion body 134 smoothly enters or leaves the wet embryo, so that the cold pressing expansion body 134 can be increased while the diameter of the cold pressing expansion body 134 is reduced. 4, because the cold-pressed expansion body 134 with an increased diameter is used to work, the expansion ratio is reduced, and the service life of the cold-pressed expansion body 134 can be increased. A cold-pressed air flow channel 132 is provided on the cold-pressed guide column 131. The equipment for filling recyclable objects fills the cold-pressed expansion body 134 with recyclable objects through the cold-pressed air flow channel 132; the equipment for extracting recyclable objects extracts the recyclable objects into the cold-pressed expansion body 134 through the cold-pressed air flow channel 132, so that negative pressure is formed in the cold-pressed air flow channel 132, and the cold-pressed expansion body 134 is received in the cold-pressed air flow channel 132.

[0271] The working process when the cold-pressed expansion body 134 is an airbag: the vacuum device draws air into the airbag through the cold-pressed guide column 131, and the airbag shrinks to a diameter smaller than the inner diameter of the container at the closing point. When the airbag is inserted into the container, the vacuum device is closed, and the inflation device injects air into the airbag through the guide. The outer wall of the inflated airbag abuts against the inner wall of the preformed wet embryo, and the airbag can adapt to and fit the inner wall of the preformed wet embryo to prevent the side wall of the preformed wet embryo from collapsing and wrinkling, and discharge excess moisture from the preformed wet embryo, thereby increasing the density and strength of the wet embryo and reducing the heating energy consumption of the next process.

Any connection method between the airbag and the cold press guide pillar 131 is acceptable, as long as the airbag is sleeved on the outside of the cold press guide pillar 131.

[0273] In a preferred embodiment of the present invention, the cold-pressed air flow channel 132 is used to store an airbag. The airbag is made of expandable material. When the vacuum device draws air into the airbag, the airbag shrinks into the cold-pressed air flow channel 132. The diameter of the airbag wrapped around the cold-pressed guide column 131 can be reduced. In this way, when the inner diameter of the product opening is constant, an airbag with a large diameter in a natural state can be selected as much as possible to reduce the airbag expansion ratio and increase the service life of the airbag.

[0274] In a preferred embodiment of the present invention, Figures 11 to 13 As shown, a cold press rectifying box 135 and a cold press base 138 arranged at the bottom end of the cold press rectifying box 135;

An air inlet nozzle and an air outlet nozzle are respectively provided on the hollow chamber. The air inlet nozzle is externally connected to a device for filling recyclable objects, and the air outlet nozzle is externally connected to a device for extracting recyclable objects or to the air. The device for filling recyclable objects expands the cold-pressed expansion body 134, thereby squeezing the inner wall of the preformed wet embryo;

[0276] In a preferred embodiment of the present invention, a cold pressing limit structure 139 is installed on the upper end of the cold pressing base 138, and the cold pressing base 138 is detachably connected to the cold pressing rectifier box 135 through a quick lock structure, and the cold pressing limit structure 139 is used to limit the left and right relative positions of the cold pressing base 138 and the cold pressing rectifier box 135, and a plurality of cold pressing expansion bodies 134 are evenly distributed on the cold pressing rectifier box 135, and the cold pressing expansion bodies 134 are used to extrude the inner wall of the preformed wet embryo;

[0277] The recyclable object is preferably gas, and the cold-pressed expansion body 134 is preferably an air bag.

[0278] Specifically, a plurality of cold press guide pillars 131 are evenly distributed on the cold press rectifying box 135, and the feeding end of each cold press guide pillar 131 is located inside the cold press rectifying box 135 (it can also be directly connected to the cold press rectifying box 135 by an air bag, and the cold press guide pillar 131 is not provided), and an air inlet nozzle and an air outlet nozzle are respectively provided on the cold press rectifying box 135, and the air inlet nozzle is externally connected to an inflation device, and the air outlet nozzle is externally connected to an equipment for extracting recyclable objects or to the air (external atmospheric pressure). Multiple groups of cold press guide pillars 131 are provided on the cold press rectifying box 135 to improve production efficiency. The cold press rectifying box 135 is a diversion structure of multiple cold press guide pillars 131 (or multiple air bags), and the air inlet nozzle on the cold press rectifying box 135 is externally connected to an inflation device, and the air outlet nozzle of the cold press rectifying box 135 is externally connected to an exhaust device or to the air (external atmospheric pressure) to ensure that multiple air bags are simultaneously inhaled or exhausted.

[0280] Specifically, a cold press one-way speed regulating valve 137 is installed at the feed end of each cold press guide column 131, and the cold press one-way speed regulating valve 137 is used to control the air intake flow rate of each cold press guide column 131. If an airbag is damaged and leaks during production, and there is no explosion-proof structure, it will cause insufficient air pressure in the remaining intact airbags, and the quality of the extruded product will be problematic. The cold press one-way speed regulating valve 137 is set as the explosion-proof structure of the airbag. When an airbag ruptures, the cold press one-way speed regulating valve 137 plays a role in ensuring that the flow rate of airflow through the damaged part is much lower than the total air intake flow rate, so it will not cause too much impact on other airbags, thereby ensuring that the remaining products can be produced normally.

[0281] In a preferred embodiment of the present invention, the cold pressure one-way speed regulating valve 137 is used to adjust the intake flow rate of a single airbag so that the pressurized gas medium in the cold pressure rectifier box 135 can flow evenly into each airbag, and the cold pressure one-way speed regulating valve 137 does not affect the air outlet of the airbag.

[0283] In a preferred embodiment of the present invention, the cold press limit structure 139 includes two cold press baffles 1310, and the two cold press baffles 1310 are arranged relatively parallel, the cold press rectifying box 135 is located between the two cold press baffles 1310, each cold press baffle 1310 is detachably connected to the upper end of the cold press base 138, one side of each cold press baffle 1310 is abutted against the outer wall of the cold press rectifying box 135, and the gap between the two cold press baffles 1310 is used to limit the relative position of the cold press rectifying box 135 on the cold press base 138. When the cold press rectifying box 135 is inserted, the two cold press baffles 1310 can play a guiding role, allowing it to smoothly enter the preset position. The gap between the two cold press baffles 1310 can be adjusted to suit different specifications of the cold press rectifying box 135.

[0284] In a preferred embodiment of the present invention, the outer wall of the cold pressure rectifier box 135 is provided with a cold pressure limit groove 136, one end of the cold pressure stop block 1311 is located in the cold pressure limit groove 136, and the other end of the cold pressure stop block 1311 is provided with a threaded hole, and an adjusting bolt is installed in the threaded hole, and one end of the adjusting bolt abuts against the cold pressure base 138 to adjust the front and rear relative position of the cold pressure rectifier box 135 relative to the cold pressure base 138, and the cold pressure stop block 1311 and the cold pressure baffle 1310 are arranged perpendicular to each other, and a through hole 416 is provided in the middle part of the cold pressure stop block 1311, and one end of the fixing bolt passes through the through hole 416 and is fixedly connected to the cold pressure base 138, and the two cold pressure stop blocks 1311 and the cold pressure baffle 1310 respectively define the four sides of the cold pressure rectifier box 135, which is convenient for positioning the cold pressure rectifier box 135.

[0285] Compared with the cold press limit structure 139 used for the positioning structure of the cold press rectifier box 135, the quick lock structure is used to quickly lock the relative position of the cold press rectifier box 135 and the cold press base 138. The quick lock structure includes a front top and a rear top. The front top includes a cold press top pin 1312 and a cold press spring 1313 arranged on its periphery, and the two ends of the cold press spring 1313 are respectively fixedly connected to the periphery of the cold press top pin 1312 and the upper end of the cold press base 138.

(It should be noted that in this embodiment, in order to complete the cleaning and air-drying work, an air pressure pipeline and a high-pressure water pipeline are arranged on the periphery of the cold pressing station, and the pipeline sprays water mist to clean the slurry suction component and then air-dry it. The air drying here adopts the existing mature blowing nozzle, and the blowing nozzle is connected to the The compressed air is connected to the cavity, and the residual slurry outside the cavity is cleaned through the cleaning and air-drying process to avoid excess slurry splashing and contaminating the subsequent workstations; the first slurry tank 101 absorbs the slurry and the second slurry tank 102 is cold-pressed to avoid the liquid from mixing into the first slurry tank 101 when cleaning the mold or the periphery of the cavity, thereby reducing the concentration of the first slurry tank 101 and affecting the product quality; after the airbag is cold-pressed, a certain amount of fiber is bound to remain on the airbag. When the cold-pressing process is completed, the airbag will also be cleaned to avoid affecting the product quality when it works next time.

[0289] After all the processes are completed, the inner mold cleaning process can be performed each time or after multiple cycles. Since some pulp fibers will remain in the inner mold during the slurry suction process, if it is not cleaned, it will cause quality problems in subsequent products. After completing the specified cycle action, the molding cavity 421 is transferred to the cold pressing station, opened to a specified angle and then dropped. The spray head set on one of the two side walls of the second slurry tank 102 in this embodiment can be driven by a transmission mechanism (it should be noted that the transmission mechanism described in this embodiment is a hydraulic rod driving a transmission rod, thereby driving the spray head to move. This transmission method is a conventional technical means well known to those skilled in the art. The transmission mechanism is not the invention point of this embodiment, so it will not be described in detail) to drive the spray head to move to the specified position, start spraying water mist for cleaning, and the slurry suction assembly moves up and down to ensure that all areas are cleaned. After cleaning, the molding cavity 421 rises and returns to the initial position, and the mold is closed.

[0290] At the same time, through the cleaning unit set inside the second slurry tank 102, when the product processing is completed and the slurry inside the second slurry tank 102 is discharged, due to the characteristics of the slurry, a large amount of fibers will remain on the surface or bottom of the second slurry tank 102, which needs to be cleaned manually. In the present invention, the cleaning unit set on the inner wall of the second slurry tank 102 is used. When the slurry is discharged, according to the actual liquid level height, when the liquid level is lower than a certain height (assuming the height of the second slurry tank 1021 / 3), liquid will flow out from the top of the slurry pool 1 along the side wall of the second slurry tank 102 to help clean the inner wall of the second slurry tank 102, and at the same time dilute the density of the slurry in the second slurry tank 102, so that the fibers can be discharged better, reducing the labor intensity of personnel and improving work efficiency.

The lateral displacement assembly 25 includes a lateral lead screw 253, a lateral nut 252 and a lateral servo motor 251. The lateral servo motor 251 is fixedly mounted on the hot pressing platform 17. The lateral lead screw 253 is fixedly mounted below the hot pressing platform 17. The outer periphery of the lateral lead screw 253 is threadedly connected to the lateral nut 252, and the lateral nut 252 is connected to the hot pressing platform 17 through a lateral connecting seat 256. The lateral nut 252 can rotate relative to the lateral connecting seat 256. The driving shaft of the lateral servo motor 251 drives the lateral nut 252 to rotate relative to each other through a synchronous structure. The synchronous structure can be a combination of gears and gears, or a combination of a lateral synchronous belt 255 and two synchronous wheels. In this embodiment, a first synchronous wheel is installed on the driving shaft, and the outer periphery of the lateral nut 252 is fixedly sleeved with a second synchronous wheel 254. The outer periphery of the first synchronous wheel is synchronously rotated with the outer periphery of the second synchronous wheel 254 through the lateral synchronous belt 255. The driving shaft of the transverse servo motor 251 drives the first synchronous wheel, the transverse synchronous belt 255, the second synchronous wheel 254 and the transverse nut 252 to rotate. The rotating transverse nut 252 and the transverse lead screw 253 rotate relative to each other to achieve linear displacement, thereby driving the transverse connecting seat 256 and the moving platform to move horizontally. Because the transverse connecting seat 256 and the transverse nut 252 can rotate relative to each other, the transverse connecting seat 256 does not interfere with the rotation of the transverse nut 252. Since the transverse servo motor 251+lead structure can accurately control the platform movement position, when it is necessary to adjust the hot pressing lower platform 17 horizontally relative to the hot pressing upper platform 18, the moving distance parameter can be input to drive the transverse servo motor 251 to drive the hot pressing lower platform 17 to move to achieve precise alignment.

The provision of power is also common knowledge in this field. This article is mainly used to protect mechanical devices.

[0323] Working process

[0324] Material loading process:

[0325] During implementation, the mold clamping power assembly 16 can be connected to the hot pressing upper platform 18 or to the hot pressing lower platform 17, one of which can be selected; the lateral movement power assembly 15 can drive the hot pressing upper platform 18 or the hot pressing lower platform 17 away from or close to the molding and cold pressing stations, one of which can be selected; the lateral movement power assembly 15 and the mold clamping assembly 3 can respectively drive the hot pressing upper platform 18 or the hot pressing lower platform 17 to move, such as Figure 18-19As shown, the present embodiment comprises four groups of hot pressing stations (each group of hot pressing stations comprises an upper hot pressing platform 18 and a lower hot pressing platform 17), namely, a hot pressing station 1 26, a hot pressing station 2 27 (the hot pressing station 1 26 and the hot pressing station 2 27 constitute a hot pressing unit 1 30), a hot pressing station 3 28, and a hot pressing station 4 29 (the hot pressing station 3 28 and the hot pressing station 4 29 constitute a hot pressing unit 2 31). The hot pressing station close to the forming transfer station 1 of the transplanting mechanism 3 is the hot pressing station 1 26, and the hot pressing station 2 27 is downstream of the hot pressing station 1 26. The hot pressing station close to the forming transfer station 2 of the transplanting mechanism 3 is the hot pressing station 3 28, and the hot pressing station 4 29 is downstream of the hot pressing station 3 28. For the convenience of explaining the movement process, the hot pressing station 1 is taken as the hot pressing station 26. Taking the workstation 26 and the second hot pressing workstation 27 as examples, a clamping power assembly 16 is arranged under each hot pressing lower platform 17, and each clamping power assembly 16 is slidably connected to the first guide rail. The clamping power mechanism of the first hot pressing workstation 26 is close to the first forming transfer position of the transfer mechanism 3. During the process, the clamping power mechanism of the second hot pressing workstation 27 drives the hot pressing lower platform 17 of the second hot pressing workstation 27 close to the bottom of the hot pressing upper platform 18 of the first hot pressing workstation 26. The transfer mechanism 3 unloads the wet embryo to the hot pressing upper platform 18 of the first hot pressing workstation 26 by blowing and peeling at a forming transfer position. Then, the two clamping power assemblies 16 and the lateral moving power assembly 15 respectively drive the two hot pressing lower platforms 17 to reset, and the first hot pressing workstation 26 performs hot pressing on the wet embryo. After the first drying, when the pre-drying setting time is reached, the two mold clamping power components 16 respectively drive the two hot pressing lower platforms 17 and the corresponding hot pressing upper platforms 18 to open the mold, and then the lateral moving power component 15 drives the hot pressing upper platform 18 of the hot pressing station 1 26 to enter the forming transfer position 1, and at the same time, the lateral moving power component 15 drives the hot pressing lower platform 17 of the hot pressing station 27 to approach the bottom of the hot pressing upper platform 18 of the hot pressing station 1 26, and the transplanting mechanism 3 unloads the wet embryo again at a forming transfer position, and the hot pressing upper platform 18 of the hot pressing station 1 26 unloads the first drying product sucked thereon to the hot pressing lower mold 19 of the hot pressing station 2 2, and then the two mold clamping power components 16 and the lateral moving power component 15 drive the two hot pressing stations 27 to enter the forming transfer position 1. The lower platform 17 is reset, the hot pressing station 1 26 performs the first drying of the wet embryo, and the hot pressing station 27 performs the second drying of the first dried product. After the second drying is completed, the dried product is collected by the cloth support structure to ensure the continuity of the hot pressing. The process of the two clamping power components 16 clamping the hot pressing lower platform 17 and the hot pressing upper platform 18 is that the transmission shaft of the second motor 166 drives the second lead screw 163 to rotate, and the clamping nut 164 is kept fixed by the first support plate 162, the hot pressing lower platform 17 and the first guide column 165. The clamping nut 164 drives the lower end of the first support plate 162 to slide linearly, and the upper end of the first support plate 162 and the hot pressing lower platform 17 are limited by the first guide column 165 to slide up and down.

[0326] The process of hot pressing the product after the hot pressing lower platform and the hot pressing upper platform are molded together:

[0327] The working principle and process of the hot pressing molding of the product in the first hot pressing station 26 and the second hot pressing station 27 are the same. When the mold closing power component 16 drives the hot pressing lower platform 17 carrying the material to approach the bottom of the hot pressing upper platform 18, the controller controls the external exhaust device to sequentially communicate with the inside of the hot pressing lower mold 19 through the air outlet of the hot pressing lower platform 17, the first air flow channel 174 and the hot pressing air hole 175, so that the wet embryo is sucked into the mold groove of the hot pressing lower mold 19, and then the mold closing power component 16 drives the hot pressing lower platform 17 to close the mold with the hot pressing upper platform 18, and the controller controls the external exhaust device to sequentially communicate with the inside of the hot pressing lower mold 19 through the air outlet of the hot pressing lower platform 18, the first air flow channel 174 and the hot pressing air hole 175. 75 is connected to the inside of the hot pressing upper mold 20 to suck and dry the wet embryo. At this time, the heating unit in the back plate 177 of the hot pressing mold simultaneously heats the upper hot pressing lower mold 19 to dry and shape the wet embryo. After the predetermined mold closing time is reached, the controller controls the external inflation device to be connected to the inside of the hot pressing lower mold 19 through the air inlet, the first air flow channel 174 and the hot pressing air hole 175 of the hot pressing lower platform 17 in sequence to blow and peel the product. At this time, the hot pressing upper mold 20 still maintains the state of sucking the product until the tooling of the downstream process is transferred to the bottom of the hot pressing upper mold 20. The hot pressing upper mold 20 blows and peels the product onto the support cloth structure, and the product enters the next process.

[0328] Working process of the thermocompression expansion assembly:

[0329] When the hot pressing lower platform 17 and the hot pressing upper platform 18 are molded together to dry and shape the product, it is also necessary to support the inside of the product. The hot pressing expansion body 2212 of the hot pressing expansion assembly 22 (or the second extrusion unit) is the supporting structure of the inner wall of the product. When the hot pressing lower platform 17 and the hot pressing upper platform 18 are molded together, the external exhaust equipment is connected to the inside of the hot pressing expansion body 2212 through the air pipe, the vent hole and the hot pressing second air flow channel 2213 in turn to vacuumize the hot pressing expansion body 2212, and the hot pressing expansion body 2212 shrinks into the through groove, so that most of the hot pressing expansion body 2212 is stacked in the through groove, so that the outer diameter of the hot pressing expansion body 2212 is smaller than the inner diameter of the bottle mouth, and then the hot pressing power component 223 drives the hot pressing rectifier box 2214, the hot pressing guide column 2211 and the hot pressing expansion body 2212 to insert into the wet product in turn. After the hot pressing power component 223 is in place, the hot pressing anti-retreat cylinder 225 drives the hot pressing anti-retreat rod 224 to be inserted into the hot pressing anti-retreat hole 2229, and then the external inflation device is connected to the hot pressing expansion body 2212 through the air pipe, the air hole and the hot pressing second air flow channel 2213 in turn for inflation. The hot pressing expansion body 2212 expands so that the outer wall of the hot pressing expansion body 2212 abuts against the inner wall of the product. After reaching the predetermined time of the hot pressing lower platform 17 and the hot pressing upper platform 18 being molded, the outer diameter of the hot pressing expansion body 2212 shrinks to a state where it can be withdrawn from the bottle mouth, and the hot pressing anti-retreat cylinder 225 drives the hot pressing anti-retreat rod 224 to pull out of the hot pressing anti-retreat hole 2229, and the hot pressing power component 223 drives the hot pressing rectifier box 2214, the hot pressing guide column 2211 and the hot pressing expansion body 2212 to reset.

[0330] In a preferred embodiment of the present invention, the hot pressing station further includes a heating device, the heating device includes a heating element and a temperature probe, the hot pressing upper mold 20 is installed in the hot pressing upper platform 18 through the hot pressing mold back plate 177, and the hot pressing lower mold 19 is installed in the hot pressing lower platform 17 through the hot pressing mold back plate 177;

[0331] The heating element is installed in the hot pressing mold back plate 177, and the heating element is used to heat the hot pressing mold back plate 177 and the mold;

[0332] The temperature probe is installed in the hot pressing mold back plate 177 and the hot pressing upper mold 20 and / or the hot pressing lower mold 19. The temperature probe is used to detect the temperature of the hot pressing mold back plate 177 and the mold. The temperature raising device is set in the controller program to start the heating element in advance before receiving the wet embryo, so that it can transfer the temperature to the mold first to counteract the cooling effect brought by the wet embryo, so that the mold can be stabilized within the required temperature range, thereby avoiding problems such as low efficiency caused by mold cooling.

[0333] In actual use, the heating element can be a thermocouple. The real-time temperature of the thermocouple is detected by a temperature probe, which can not only prevent excessive heating, improve equipment reliability and ensure production safety; but also directly act on the mold, so the temperature control accuracy in the mold is high and the temperature control response speed is sensitive.

[0334] In a second aspect, based on the same concept, the embodiment of the present application further provides a process for manufacturing a plant fiber container, comprising the following steps:

[0335] It includes a molding cavity 421 for forming a wet embryo and a hot pressing cavity for drying the wet embryo. The hot pressing lower mold 19 and the hot pressing upper mold 20 form the hot pressing cavity.

[0336] The molding cavity 421 enters the slurry in the first slurry tank 101;

[0337] The opening of the molding cavity 421 faces downward;

[0338] The slurry in the first slurry tank 101 enters the molding cavity 421 through the cavity opening of the molding cavity 421, and the air in the molding cavity 421 is discharged from the upper part of the molding cavity 421 by connecting to the external atmospheric pressure or vacuuming. Through the vacuuming method, the liquid in the slurry is discharged through the filtering structure in the molding cavity 421, and the remaining plant fibers are attached to the filtering structure to complete the slurry absorption;

[0339] Preferably, when the forming cavity 421 enters the pulp pool 1, because the liquid density is greater than the air density, the air moves to the upper part of the cavity and is discharged through the outlet connected to the external atmospheric pressure. This method can fill the cavity with slurry, and then use vacuum suction to start sucking the slurry, and the plant fibers are attached to the filter structure.

[0340] Alternatively, when the forming cavity 421 enters the pulp pool 1, because the liquid density is greater than the air density, the air moves to the upper part of the cavity and is discharged through the connected equipment for extracting recyclable objects. This method can fill the cavity with slurry, and then use vacuum suction to start sucking the slurry, and the plant fibers are attached to the filter structure.

[0341] The forming cavity 421 is separated from the slurry surface, and the excess water of the plant fibers attached to the filtering structure is discharged by vacuuming to form a preformed wet embryo;

[0342] The expandable cold-pressed expansion body 134 enters the molding cavity 421 through the cavity opening, squeezes the inner wall of the preformed wet embryo, completes the cold pressing, and forms the wet embryo;

[0343] The wet embryo after the cold pressing process is received by the hot pressing cavity, and the hot pressing cavity heats and dries the outside of the wet embryo. The expandable hot pressing expansion body 2212 enters the inner wall of the wet embryo and squeezes it, completing the hot pressing process to obtain a dry embryo.

[0344] In a preferred embodiment of the present invention, the wet embryo formation process comprises:

[0345] The transplanting mechanism 3 drives the slurry suction assembly to move to the slurry suction station, and the molding cavity 421 penetrates below the liquid level of the first slurry tank 101;

[0346] Controlling the slurry suction component to execute a preset slurry suction control strategy at a first preset time, so that the slurry suction component completes vacuum suction of slurry, and the plant fiber is adsorbed on the filter structure of the front-end mold;

[0347] After the slurry suction is completed, the slurry suction component is driven to rise above the liquid level of the first slurry tank 101, and the slurry suction component is controlled to execute a preset slurry suction control strategy to extract excess water from the plant fibers adsorbed on the filter structure, and dehydrate to form wet embryos, wherein the slurry suction control strategy is used to control the slurry suction component to complete the slurry suction and dehydration operations;

[0348] The transplanting mechanism 3 drives the slurry suction component to move horizontally to the cold pressing station. After reaching the predetermined position, the slurry suction component descends, and the cold pressing expansion body 134 extends into the molding cavity 421 along the cavity opening. The cold pressing expansion body 134 expands to squeeze the inner wall of the preformed wet embryo in the molding cavity 421, discharges free water, and forms a wet embryo.

[0349] Specifically, in this embodiment, the wet embryo forming process includes a slurry absorption process and a cold pressing process.

[0350] Among them, during the slurry absorption process, vertical slurry absorption operation is adopted to help the wet embryo to be evenly formed, and there will be no slurry leakage and the like. Since the cavity mouth of the molding cavity 421 described in this embodiment is set downward, the cavity mouth of the molding cavity 421 is finally separated from the liquid surface of the slurry pool, which increases the slurry absorption time at the closing point of the container product, thereby increasing the fiber layer thickness at the closing point of the container product, effectively solving the problem of thin and uneven thickness at the closing point, and ensuring that the wall thickness of the plant fiber container product is uniform; during the cold pressing process, the cold pressing expansion body 134 is expanded to extrude the inner wall of the preformed wet embryo in the molding cavity 421, discharge free water, obtain the wet embryo, increase the structural strength of the wet embryo, improve the production quality and product qualification rate of the wet embryo, and greatly meet the market demand.

[0351] In this embodiment, in order to ensure that the opening of the forming cavity 421 finally leaves the liquid surface of the pulp pool, the opening of the forming cavity 421 is set downward, and the following explanation is now given:

[0352] First, before entering the pulp pool 1, the opening of the forming cavity 421 can be set downward.

[0353] Secondly, after the slurry suction action is completed and the slurry suction assembly is separated from the liquid surface of the slurry pool, the slurry suction assembly can be flipped over by a mechanical arm so that the cavity opening is set downward in the current state.

[0354] Thirdly, when the slurry suction operation is being performed, that is, after entering the slurry pool liquid surface, the robot arm can be controlled to flip the slurry suction assembly so that the cavity opening in the current state is set downward.

[0355] The purpose of the several methods provided above is to ensure that the opening of the molding cavity 421 faces downward, and when the molding cavity 421 is separated from the liquid surface, excess slurry is discharged from the opening of the molding cavity 421 to ensure that the wall thickness of the container product is uniform.

[0361] The through hole 432 is connected to the air compressor device through the air compressor pipe 6 and to the vacuum device through the vacuum pipe 7; and\or, the through hole 432 is connected to the external atmospheric pressure;

[0362] Specifically, to ensure that the paper-plastic product is completely formed, if the molding cavity 421 is not connected to the external atmospheric pressure, there will be gas in the cavity, the gas cannot be discharged, and the liquid cannot fill the entire cavity, so that the paper-plastic product cannot be completely formed. The molding cavity 421 or cavity 431 described in this embodiment needs to be connected to the external atmospheric pressure, the purpose is to discharge the gas in the molding cavity and control the negative pressure in the cavity; or by opening a vacuum at the top of the molding cavity 421 or cavity 431, the slurry can be sucked and / or exhausted, and the molding of the paper-plastic product can also be achieved.

[0370] The transplanting mechanism 3 drives the slurry suction component to move horizontally to the cold pressing station. After reaching the predetermined position, the slurry suction component descends, and the cold pressing expansion body 134 extends into the molding cavity 421 along the cavity opening. The cold pressing expansion body 134 expands to squeeze the inner wall of the preformed wet embryo in the molding cavity 421, discharges free water, and forms a wet embryo.

[0371] During the slurry suction process, the slurry suction component is driven to move to the slurry suction station by controlling the transplanting mechanism 3. The slurry suction station described in this embodiment is located directly above the first slurry tank 101, and vertically penetrates to below the slurry liquid level in the first slurry tank 101. The slurry suction component is controlled to execute the slurry suction control strategy to vacuum suck the slurry, and the slurry is sucked into the molding cavity 421 along the cavity mouth, thereby completing the slurry suction work; after completing the slurry vacuum suction operation, so that the plant fiber is adsorbed on the filtering structure of the molding cavity 421, the transplanting mechanism 3 drives the slurry suction component to vertically rise to above the slurry liquid level in the first slurry tank 101, and the slurry suction component is controlled to execute the slurry suction control strategy to suck the moisture in the slurry suction component to form a wet embryo, and then enters the cold pressing process.

[0372] During the cold pressing process, the slurry suction component is driven by the transplanting mechanism 3 to move horizontally to the cold pressing station. The cold pressing station described in this embodiment is located directly above the second slurry groove 102. The slurry suction component is controlled to descend, and the molding cavity 421 is controlled to penetrate into the second slurry groove 102. The cold pressing expansion body 134 arranged in the second slurry groove 102 penetrates into the molding cavity 421 along the cavity mouth. After the cold pressing expansion body 134 accurately enters the molding cavity 421 and is in place, the external inflation and deflation equipment controls the cold pressing expansion body 134 to expand, squeeze the inner wall of the preformed wet embryo in the molding cavity 421, discharge free water, and obtain a wet embryo.

[0373] The wet embryo formation process described in this embodiment controls the slurry flow and pressure in the cavity 431 by executing the slurry suction control strategy in the slurry suction process, thereby realizing the molding operation of the container product. This embodiment can meet the requirements of wall thickness, strength, density, etc. of the product. When there are multiple cavities, the requirements of wall thickness, strength, density, etc. of the specified area can be met; compared with traditional paper plastic equipment, when the pressure and flow in the molding process fluctuate, the flow and pressure in the molding process can be detected and adjusted in real time to ensure the consistency of the product; by expanding the cold pressing expansion body 134 in the cold pressing process, the inner wall of the preformed wet embryo in the molding cavity 421 is squeezed to discharge free water to obtain the wet embryo, thereby increasing the structural strength of the wet embryo, improving the production quality and product qualification rate of the wet embryo, and greatly meeting the market demand.

[0374] In a preferred embodiment of the present invention, the slurry suction control strategy includes:

[0375] In response to the slurry suction state of the plant fiber slurry, the switch valve 8 is controlled to be opened, and the regulating valve 9 is controlled to be opened with a first valve opening, and the slurry is vacuum-sucked to complete the slurry suction operation;

[0376] In response to the dehydration or transfer state of the preformed wet embryo, the switch valve 8 is continuously controlled to be opened, and the regulating valve 9 is controlled to be adjusted from the first valve opening to the second valve opening, so as to extract the excess water of the plant fiber adsorbed on the filter structure to dehydrate and form the preformed wet embryo, wherein the second valve opening is not less than the first valve opening;

[0377] In response to the state of peeling off the wet embryo from the inner wall of the preformed wet embryo or the non-working state, the switch valve 8 is controlled to close and the regulating valve 9 to restore to the first valve opening, waiting for the next slurry suction instruction; wherein, the switching state and the state of peeling off the wet embryo are the states of the hot pressing process performed after the cold pressing process is completed.

[0378] It should be noted that the switch valve 8 used in the present application is used to control the on-off of the flow path, and the regulating valve 9 is used to control the flow rate of the flow path. The valves that can realize the function of the switch valve 8 include but are not limited to angle valves, ball valves, butterfly valves and other switch valves 8. The preferred scheme of this embodiment adopts angle valve control. The regulating valve 9 used in this embodiment is a stop valve, throttle valve and other regulating valves 9. The preferred scheme of this embodiment adopts stop valve control. The stop valve slowly controls the flow regulation, and the angle valve quickly responds to the flow switch. A small flow is required when sucking slurry, and a large flow is required when dehydrating. The flow change is a molding requirement. Therefore, this embodiment adopts angle valve and stop valve to cooperate to achieve it.

[0379] The angle valve and the stop valve can be automatically adjusted in real time by means of electric control or pneumatic control. This embodiment does not specifically limit the specific electric control or pneumatic control method, that is, it can complete the slurry suction, dehydration and stripping processes of the container product. Technical personnel in this field can select a specific control method according to the actual site conditions. For the specific control means of each valve, please refer to the following control method, which will not be repeated here.

[0380] Furthermore, since the flow rates required for the slurry suction and dehydration processes are different, the flow rates need to be adjusted in real time. The present application adopts a method of coordinating the switch valve 8 and the regulating valve 9 to control the slurry suction flow rate and the dehydration flow rate by controlling the switch valve 8 and the regulating valve 9 to meet the molding requirements of the container product in the slurry suction and dehydration processes.

[0381] This application adopts stop valve + angle valve control, the stop valve is used to control the size of the switch. Since the stop valve or other flow control valves have a slow adjustment speed and cannot meet the instant switching needs, an angle valve is added for control, that is, the stop valve is adjusted to the slurry suction state. When the slurry suction starts, the angle valve opens. When the dehydration state is entered, the stop valve is adjusted normally to control the flow rate. When the stripping state or non-working state is entered, the angle valve is closed and the stop valve is adjusted to the slurry suction state.

[0382] In a preferred embodiment of the present invention, it also includes:

[0388] In response to the non-operating state, the switch valve 8 is controlled to be closed.

[0389] Specifically, in response to the wet embryo peeling state and the non-working state, this embodiment controls the opening or closing of the switch valve 8 provided on the air pressure pipeline 6 to control the inflow and outflow of external gas into the cavity 431 .

[0390] or;

[0392] In response to the wet embryo peeling state, the switch valve 8 is controlled to be opened, and the regulating valve 9 is in a regulating control state to adjust the flow rate and / or pressure;

[0393] In response to the non-operating state, the switch valve 8 is controlled to be closed.

[0394] Specifically, in response to the wet embryo peeling state, the present embodiment controls the opening or closing of the switch valve 8 provided on the air pressure pipeline 6, and at the same time, adjusts the valve opening of the regulating valve 9 to adjust the flow rate and / or pressure.

[0395] By controlling the opening and closing of the switch valve 8 and the regulating valve 9 through a control method, the flow and pressure of the slurry in the cavity 431 can be controlled. When the molding operation of the container product is realized, the present application can meet the requirements of the wall thickness, strength, density, etc. of the product. When there are multiple cavities, the requirements of the wall thickness, strength, density, etc. of the specified area can be met. Compared with traditional paper-molding equipment, when the pressure and flow in the molding process fluctuate, the flow and pressure in the molding process can be detected and adjusted in real time, thereby ensuring the consistency of the product, improving the product qualification rate of the container product, and greatly meeting the market demand.

[0396] In a preferred embodiment of the present invention, the cold-pressed expansion body 134 is sleeved on the periphery of the cold-pressed guide column 131, and the cold-pressed guide column 131 is a supporting structure of the cold-pressed expansion body 134. A cold-pressed air flow channel 132 is provided on the cold-pressed guide column 131. A device for filling recyclable objects fills recyclable objects into the cold-pressed expansion body 134 through the cold-pressed air flow channel 132, and a device for extracting recyclable objects extracts recyclable objects into the cold-pressed expansion body 134 through the cold-pressed air flow channel 132, so that negative pressure is formed in the cold-pressed air flow channel 132, and the cold-pressed expansion body 134 is received in the cold-pressed air flow channel 132.

[0397] In response to the cold pressing state of the preformed wet embryo, the cold-pressed expansion body 134 enters the molding cavity 421, the device for extracting recyclable objects is closed, and the external device for filling recyclable objects fills the inside of the cold-pressed expansion body 134, and the cold-pressed expansion body 134 expands so that the outer wall of the cold-pressed expansion body 134 abuts against the inner wall of the preformed wet embryo to squeeze it;

[0398] After the cold-pressed expansion body 134 completes the extrusion process, the equipment for filling recyclable objects is closed, and the equipment for extracting recyclable objects is opened. The cold-pressed expansion body 134 shrinks into the cold-pressed air flow channel 132, the cold-pressed expansion body 134 separates from the wet embryo, the equipment for extracting recyclable objects is closed, and the transplanting mechanism 3 drives the slurry suction assembly to rise to the transfer position.

[0399] In a preferred embodiment of the present invention, dry embryo formation comprises:

[0400] The upper hot pressing platform 18 and the lower hot pressing platform 17 are heated to the specified temperature. When the slurry suction component completes the molding or cold pressing process, the transfer mechanism 3 drives the slurry suction component to rotate and open the mold and move to the transfer position. The lower hot pressing platform 17 descends and transfers to the transfer position. The lower hot pressing platform 17 rises and closes the mold with the slurry suction component.

[0401] The slurry suction component starts air pressure to peel off the wet embryo, and the hot pressure lower platform 17 starts vacuum adsorption of the wet embryo to complete the transfer;

[0402] The lower hot pressing platform 17 descends and returns to the hot pressing position, and then rises and closes the mold with the upper hot pressing platform 18;

[0403] Then the hot pressing chamber opens the vacuum;

[0404] The hot-pressing expansion body 2212 starts vacuum to absorb the hot-pressing expansion body 2212 into the conduit of the hot-pressing expansion body 2212 and probe into the wet embryo in the hot-pressing cavity. Then, the hot-pressing expansion body 2212 starts air pressure expansion and forms a combined force with the hot-pressing lower mold 19 and the hot-pressing upper mold 20 to squeeze the wet embryo, thereby compacting the wet embryo and drying the wet embryo.

[0405] When the wet embryo is completely dried, the dry embryo is obtained.

[0407] In a preferred embodiment of the present invention, shaping refers to applying pressure to the product during hot pressing, thereby adding concave and convex patterns to the product, and at the same time completing the production of the threaded opening of the hollow container product.

[0408] In a preferred embodiment of the present invention, hot blowing refers to blowing high-temperature high / low-pressure air into the interior of the hollow product while hot pressing to increase gas flow and accelerate drying.

[0409] In a third aspect, based on the same concept, the embodiment of the present application further provides a hot pressing advance heating process, which is used in the process of heating and drying the wet embryo produced by the pulp molding process, including:

[0414] In this embodiment, the temperature extreme value is used to prevent the mold temperature from being overheated and thus damaging the product (the temperature of the mold is directly detected in the present invention, while the temperature monitoring in traditional equipment exists in the hot pressing platform). This temperature is only effective during the advance heating cycle.

[0415] The heating power is used to adjust the speed of heating;

[0418] No, that is, if the mold temperature does not reach 160℃ within 10 seconds before receiving the material, the heating element will stop when receiving the material, and will not work normally until the mold returns to 150℃.

[0419] Case 2: The mold working temperature is 155°C, the temperature rises by 8s in advance, the lag time is 5s, the temperature rise limit is 170°C, the heating power is 4kw, and the current mold temperature is 150°C;

If so, the heating element stops when the temperature is reached, and it will not work normally until the mold returns to 155℃.

[0421] No, that is, heating starts until the mold reaches 170℃ 5s after receiving the material. At this time, the heating element stops and works normally until it returns to 155℃.

[0422] Case 3: The mold working temperature is 140℃, the advance heating time is 0s, the lag time is 7s, the temperature rise limit is 165℃, the heating power is 3kw, and the current mold temperature is 140℃;

[0423] When receiving the material, the heating tube works (3kw), and it is judged whether the mold temperature reaches 170℃ within 7s after starting heating and receiving the material. If so, the heating element stops when the temperature is reached, and it will not work normally until the mold returns to 155℃.

[0424] No, that is, heating starts until the mold does not reach 170℃ 7s after receiving the material. At this time, the heating element stops and works normally until it returns to 155℃.
