Description

Technical Field

[0001] The invention belongs to the field of plant fiber container wet embryo processing, and in particular relates to plant fiber container wet embryo processing equipment and technology. Background Art

[0002] Plant fiber mold container wet embryo processing uses plant fiber as raw material, and a special mold is used on a molding machine to shape a paper product with a certain shape. The production process is completed by pulping, slurry suction, cold pressing, drying and shaping. Plant fiber molding has the advantages of green environmental protection and renewable raw materials. It is mainly used for lunch boxes, tableware, product trays, etc.

[0003] When making closed-end container products, traditional equipment mostly adopts 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, the area can no longer absorb slurry, while the area below the liquid level will continue to absorb slurry, and the remaining slurry inside the paper plastic container 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 side wall of the upper half of the paper plastic container and the side wall of the lower half. This phenomenon is commonly known as pulp 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] The dehydration process is to keep the vacuum on after the mold is separated from the slurry to drain excess water from the wet embryo.

[0006] In the cold pressing process of closed-end container products, the plant fiber container formed by slurry absorption needs to be squeezed and excess water needs to be further discharged to increase the structural strength of the wet embryo. Usually, an expansion body is installed on the tooling that applies pressure inside the product, and the expansion body is inflated and deflated to achieve extrusion and shaping of the inner wall of the product. The expansion body is a wearing part with a short service life, high replacement frequency and use cost, which affects the production quality of the product.

[0007] The problems existing in the above two processes easily lead to poor quality and qualified rate of plant fiber container processing products, low production efficiency and high cost, making it difficult to meet market demand. Summary of the invention

[0008] In view of this, the present invention aims to provide a plant fiber container wet embryo processing device and process to solve at least one of the above problems.

[0009] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0010] In a first aspect, the present invention provides a plant fiber container wet embryo processing device, the processing device comprising:

[0011] Slurry tank, frame assembly, transplanting mechanism, slurry suction assembly and cold pressing assembly;

[0012] The transplanting mechanism is arranged on the frame assembly;

[0013] The slurry suction component has a built-in molding cavity;

[0014] The slurry suction component and the first slurry tank liquid surface of the slurry pool are moved relative to each other through the transplanting mechanism, the slurry suction component penetrates into the first slurry tank liquid surface, and the slurry in the first slurry tank enters the molding cavity 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 faces downward, and the slurry suction component is away from the first slurry tank liquid surface, completing the preforming of the plant fiber container wet embryo;

[0015] The cold pressing component includes an expansion body, which can enter the molding cavity along the cavity opening. The expansion body is filled with recyclable objects to expand the expansion body so as to extrude the inner wall of the preformed wet embryo in the molding cavity to form a plant fiber container wet embryo.

[0016] In a second aspect, based on the same concept, the present invention further provides a plant fiber container wet embryo processing process, comprising:

[0017] The invention comprises a forming cavity for forming a wet embryo of a plant fiber container;

[0018] The forming cavity enters the slurry;

[0019] The opening of the molding cavity faces downward;

[0020] The slurry enters the molding cavity through the cavity opening of the molding cavity, and the air in the molding cavity is discharged from the upper part of the molding cavity 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, and the remaining plant fibers are attached to the filtering structure to complete the slurry absorption;

[0021] The forming cavity is separated from the slurry liquid surface, and the excess water of the plant fibers attached to the filtering structure is discharged by vacuuming to form a preformed wet embryo;

[0022] The expandable expansion body enters the molding cavity through the cavity opening, squeezes the inner wall of the preformed wet embryo, and completes the cold pressing.

[0023] Compared with the prior art, the plant fiber container wet embryo processing equipment and process of the present invention have the following beneficial effects:

[0024] (1) The plant fiber container wet embryo processing equipment and process described in the present invention adopts the form of vertical slurry suction operation, so that the cavity mouth of the molding cavity is finally separated from the liquid surface of the slurry pool, so that the slurry suction time at the closing of the container product is increased, thereby increasing the thickness of the fiber layer 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;

[0025] By controlling the slurry flow and pressure in the cavity, the paper-plastic container products can be formed (wet embryos) to meet the requirements of wall thickness, strength, density, etc. When there are multiple cavities, the wall thickness, strength, density, etc. of the specified area can be met, thereby ensuring the consistency of the product, improving the product qualification rate of paper-plastic containers, and greatly meeting the market demand;

[0026] By inflating and deflating the expansion body and utilizing the shrinkable characteristics of the expansion body, it is ensured that the expansion body smoothly enters or leaves the product, and the scratches of the expansion body are reduced, thereby increasing the service life of the expansion body.

[0027] (2) The plant fiber container wet embryo processing equipment and process of the present invention utilizes the form of inflating and deflating the expansion body and the shrinkable characteristics of the expansion body so that the expansion body can be retracted into the guide column to ensure that the 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;

[0028] 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.

[0029] (3) The plant fiber container wet embryo processing equipment or process described in the present invention not only meets the high quality requirements of the product wet embryo production, but also improves the product qualification rate and greatly increases the service life of the equipment's vulnerable parts.

[0030] (4) In the present invention, the molding cavity enters the slurry pool, and the interior of the molding cavity is in a closed state. The air inside the cavity cannot be discharged, and the liquid cannot fill the entire cavity. As a result, when the vacuum is turned on to suck the slurry, the gas and liquid inside the cavity are mixed, causing serious disturbance, resulting in product damage. Connecting the top of the cavity to the external atmospheric pressure or adding a vacuum pump can discharge excess air inside the cavity to avoid product damage. At the same time, controlling the size of the pipe opening connected to the external atmospheric pressure can adjust the negative pressure inside the cavity, thereby controlling the wall thickness of the product being formed.

[0054] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0055] See also Figure 1 and Figure 2 As shown, in the first aspect, this embodiment provides a plant fiber container wet embryo processing device, the processing device comprising:

[0056] Slurry pool 1, frame assembly 2, transplanting mechanism 3, slurry suction component and cold pressing component 13;

[0057] The transplanting mechanism 3 is arranged on the frame assembly 2;

[0058] The slurry suction assembly has a built-in molding cavity 421;

[0059] 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, 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, completing the preforming of the plant fiber container wet embryo;

[0060] The cold pressing component 13 includes an expansion body 134, which can enter the molding cavity 421 along the cavity opening. The expansion body 134 is filled with recyclable objects to expand the expansion body 134. The recyclable objects are preferably gas, and the expansion body 134 is preferably an air bag to extrude the inner wall of the preformed wet embryo in the molding cavity 421 to form a plant fiber container wet embryo.

[0061] Specifically, in the present embodiment, the servo motor driving the transplanting mechanism 3 is controlled to work through the transplanting mechanism 3 arranged on the frame assembly 2, and the mechanical arm is driven to rise and fall and move left and right through the vertically arranged chain transmission, and the mechanical arm 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, and at the same time, the slurry suction operation of the slurry suction component is performed through the cooperation of the external control device; the flow rate and pressure in the slurry suction component are controlled to complete the preforming work of the plant fiber container wet embryo; after the slurry suction operation is completed, the transplanting mechanism 3 drives the slurry suction component to enter the cold pressing station, and the expansion body 134 is used to enter the molding cavity 421 along the cavity mouth by using the expansion body arranged in the cold pressing component, and the recyclable objects are filled into the expansion body 134 to expand the 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 obtain the molded plant fiber container wet embryo.

[0062] 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.

[0063] 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.

[0064] It should be noted that the transplanting mechanism 3 described in this embodiment is a conventional technical means well known to those skilled in the art, and will not be further described here; at the same time, the control system for driving and controlling the transplanting mechanism 3 shares a control system with the entire paper plastic molding production line. The control system involved in this embodiment is a conventional technical means well known to those skilled in the art, and the present invention does not improve it, so it will not be further described.

[0065] like Fig.11 , Fig.16 and Fig.17 As shown, the expansion body 134 described in this embodiment is an air bag. Fig.11 As shown, the guide post 131 is a supporting structure of the airbag, and the guide post 131 is connected to an external inflation device and / or an air extraction device through an air pipe to achieve the expansion or contraction of the airbag. The inflation device can fill the airbag with recyclable objects through the guide post 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 squeeze the inner wall of the preformed wet embryo.

[0066] 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.

[0067] The plant fiber container wet embryo processing equipment described in this embodiment controls 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 molding cavity 421 is set toward the liquid surface of the first slurry tank 101. When the slurry suction component is separated from the liquid surface of the first slurry tank 101, excess slurry will flow out through the cavity opening.

[0068] By controlling the flow rate and pressure inside 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 fiber is attached to the molding cavity 421 of the slurry suction component and dehydration is completed, thereby realizing the pre-forming of the plant fiber container wet embryo; then, the slurry suction component is controlled to be transplanted to the cold pressing station through the transplanting mechanism 3, and the expansion body 134 provided in the cold pressing component is used to extrude the inner wall of the plant fiber container in the molding cavity 421 to discharge excess water, thereby obtaining a molded plant fiber container wet embryo.

[0069] 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 of the container product is increased, thereby increasing the thickness of the fiber layer 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 421 is separated from the liquid surface, the excess slurry is discharged from the cavity mouth of the molding cavity 421, solving the problem of uneven wall thickness of the container product caused by horizontal slurry suction in traditional equipment, and ensuring 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 when it is separated from the liquid surface, the excess slurry is discharged from the cavity mouth.

[0070] 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 plant fiber container in the molding cavity 421 to discharge excess moisture and increase the structural strength of the plant fiber container.

[0071] The plant fiber container wet embryo processing equipment described in this embodiment realizes the processing and forming of the plant fiber container wet embryo by adopting vertical slurry suction operation and cold pressing operation of inflation of the expansion body 134, which effectively improves the product quality and product qualification rate of the plant fiber container processing and greatly meets the market demand.

[0072] In some embodiments, Figures 3 to 7As 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.

[0073] Specifically, the slurry suction assembly described in this embodiment is configured by setting up a plurality of molding mold components 4, wherein 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.

[0074] 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.

[0075] like Figure 6 and Figure 7 As shown, the molding die member 4 includes a molding assembly 41, a front end die 42 and a die back plate 43;

[0076] The front end mold 42 is installed on the molding assembly 41, and the molding assembly 41 is detachably connected to the mold back plate 43. The mold back plate 43 is provided with a locking mechanism 5 to lock and fix the molding assembly 41 and the mold back plate 43;

[0077] Specifically, in this embodiment, a locking mechanism 5 is provided on the mold back plate 43 , and an operator manipulates the locking mechanism 5 to complete the rapid disassembly and assembly of the molding assembly 41 and the mold back plate 43 .

[0078] A molding cavity 421 is provided in the front mold 42, and one or more cavities 431 are provided in the mold back plate 43. The cavity 431 is connected to the molding cavity 421. Each cavity 431 is provided with one or more through holes 432, and the through holes 432 are connected to external equipment through connecting pipes.

[0079] Specifically, the front end mold 42 described in this embodiment is provided with a molding cavity 421, and the molding cavity 421 is connected to the cavity 431 provided on the mold back plate 43. The cavity 431 is connected to the 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.

[0080] The front end mold 42 is connected to the 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.

[0081] In some embodiments, Figure 8 and Fig. 9 As shown, the molding assembly 41 includes a mold base plate 411 and a mold backing plate 412;

[0082] At least one flow area is provided on the mold substrate 411, and a first flow passage hole 413 is provided in the flow area;

[0083] The mold pad 412 is detachably connected to the mold base plate 411 , and the mold pad 412 is arranged corresponding to the flow area. The mold pad 412 is provided with a second flow through hole 414 that can communicate with the first flow through hole 413 .

[0084] Specifically, in this embodiment, the mold plate is provided as a detachable mold base plate 411 and a mold pad 412, at least one flow area is divided on the mold base plate 411, the mold pad 412 is arranged corresponding to the flow area, a first flow through hole 413 is provided in each flow area, and a second flow through hole 414 that can be connected to the first flow through hole 413 is provided on the mold pad 412, so that the plant fiber slurry can pass through the first flow through hole 413 and the second flow through hole 414.

[0085] Furthermore, if Figure 8 and Fig. 9 As shown, this embodiment is explained by taking two flow areas and two mold pads 412 as an example. 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;

[0086] A plurality of fourth flow passage holes are arranged along the second direction, and a second gap is reserved between adjacent fourth flow passage holes;

[0087] The fourth flow-through hole is located below the third flow-through hole.

[0088] It should be noted that the first direction described in this embodiment is a 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 described in this embodiment is a horizontal direction, and a plurality of fourth flow through holes are correspondingly arranged below the third flow through holes.

[0089] In this embodiment, taking a bottle-shaped paper-plastic container product as an example, it can be extended to a closed container with an opening, the third flow through hole corresponds to the upper half of the bottle-shaped paper-plastic container product, and the fourth flow through hole corresponds to the lower half of the bottle-shaped paper-plastic 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 paper-plastic container product. The two types of flow through holes are set mainly to correspond to the shape of the processed product. In this embodiment, the bottle-shaped paper-plastic container product is divided into a bottle body and a bottle mouth, and the required flow rate or flow rate is different for consideration.

[0090] It should be noted that this embodiment does not specifically limit the specific circulation area and the number of mold pads 412. The number and size of the mold pads 412 described in this embodiment can be flexibly selected according to actual on-site conditions to meet the needs of container products with different structures, and has strong adaptability.

[0091] 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.

[0092] In some embodiments, Fig. 9 As shown, a plurality of internal fixing holes 415 are provided on the mold substrate 411;

[0093] The mold backing plate 412 is provided with a through hole 416 which can communicate with the inner fixing hole 415 .

[0094] Specifically, in order to install the mold pad 412 on the mold substrate 411, the present embodiment sets a plurality of internal fixing holes 415 at the edges or the middle of the mold substrate 411, sets through holes 416 connected to the internal fixing holes 415 on the mold pad 412, and sets mounting holes corresponding to the internal fixing holes 415 on the front end mold 42. 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 described in 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.

[0095] 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.

[0096] In some embodiments, 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.

[0097] 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 described in this embodiment is not shown in the accompanying drawings.

[0098] In some embodiments, Figure 6 As shown, both sides of the mold back plate 43 are provided with limiting plates 418, and corresponding inner grooves are provided on the limiting plates 418 on both sides to form a guide slideway for pulling the forming component 41;

[0099] A positioning block 419 is provided on the mold substrate 411 for positioning the mold substrate;

[0100] The number of the positioning blocks 419 is at least two;

[0101] A handle 4110 is also provided at one end of the mold substrate 411;

[0102] Specifically, in this embodiment, positioning blocks 419 are respectively provided at both ends of the mold substrate 411, and the positioning blocks 419 can be used to position the mold substrate 411 to ensure repeated installation and positioning requirements. 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.

[0103] like Figure 6 and Figure 7As shown, one end of the mold back plate 43 is provided with a limiting block 4111 corresponding to the positioning block 419 away from the end of the handle 4110;

[0104] The other end of the mold back plate 43 is provided with a positioning locking member 4112 corresponding to the positioning block 419 near the end of the handle 4110;

[0105] Specifically, guide grooves are provided on both sides of the 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 mold back plate 43, and a notch corresponding to the positioning block 419 is provided on the limit block 4111. After the mold base plate 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 mold back plate 43 is cooperated with, and the positioning locking piece 4112 is used to lock the positioning block 419 set near the handle 4110 end to ensure repeated installation and positioning requirements.

[0106] It should be noted that the positioning locking member 4112 described in 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.

[0107] In some embodiments, Figures 3 to 7 As shown, the locking mechanism 5 includes a locking unit 51 and a pull rod 52;

[0108] The locking unit 51 is disposed on the mold back plate 43 , and the driving rod 52 releases or compresses 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 mold back plate 43 to be locked or disengaged.

[0109] like Fig.10 As shown, the locking unit 51 includes a mounting block 511 disposed on the mold back plate 43, 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 pull rod 52 is disposed through the mounting block 511;

[0110] 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;

[0111] The pull 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 pull rod 52 to squeeze or release the contact 513 .

[0112] Specifically, the pull 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 pull 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 mold back plate 43 to separate; the pull rod 52 is pulled or rotated, and the contact 513 moves along the direction of the groove 53 opened on the pull rod 52. Since the bottom end face of the groove 53 is an inclined surface, the outer surface of the pull 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 mold back plate 43 to be locked.

[0113] It should be noted that the elastic compression member 514 described in this embodiment is in the form of a spring 1313, and the spring 1313 is sleeved on the connecting column 512, and the elastic force of the spring 1313 itself is utilized to realize the action of the locking block 516.

[0114] In this embodiment, a locking mechanism 5 is provided on the mold back plate 43, and the locking unit 51 and the pull rod 52 provided on the locking mechanism 5 cooperate to quickly position the molding component 41. The locking mechanism 5 is operated 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.

[0115] In some embodiments, 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;

[0116] 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 wet embryo.

[0117] 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 paper-plastic 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-plastic 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 paper-plastic containers, and greatly meeting market demand.

[0118] In some embodiments, the vacuum pipe 7 and the compressed air pipe 6 are provided with a switch valve 8 for controlling the switch of the pipes;

[0119] 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;

[0120] 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.

[0121] 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.

[0122] In some embodiments, 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;

[0123] The cavity 431 is provided with a pressure detection unit 12 for detecting the pressure in the cavity.

[0124] 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.

[0125] The pressure regulating pipe 10 described in this embodiment 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.

[0126] 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.

[0127] It should be noted that the pressure detection unit 12 described in 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.

[0128] In some embodiments, in response to a plurality of cavities 431 being provided in the slurry suction assembly, the internal gases or liquids of the plurality of cavities 431 are not connected to each other.

[0129] 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.

[0130] 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 paper-plastic container, and the lower cavity 431 corresponds to the bottle neck and the mouth of the paper-plastic container. 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.

[0131] 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).

[0132] In some embodiments, Fig.14 and Fig.15As shown, the cold pressing component 13 is arranged in the second pulp groove of the pulp pool 1; the cold pressing component also includes a guide column 131, and the expansion body 134 is sleeved on the periphery of the guide column 131, and the guide column 131 is a supporting structure of the expansion body 134, and the guide column is used to support the expansion body so that the expansion body 134 has a certain stiffness, thereby ensuring that the expansion body 134 can smoothly enter or leave the product, so that the diameter of the expansion body 134 can be increased while reducing the scratches of the expansion body 134. Since the expansion body 134 with an increased diameter is used for work, the expansion ratio is reduced, and the service life of the expansion body 134 can be increased. An air flow channel 132 is provided on the guide column 131, and a device for filling recyclable objects fills recyclable objects into the expansion body 134 through the air flow channel 132; a device for extracting recyclable objects extracts recyclable objects into the expansion body 134 through the air flow channel 132, so that a negative pressure is formed in the air flow channel 132, and the expansion body 134 is received in the air flow channel 132. Working process of the airbag: the vacuum device draws air into the airbag through the guide column 131, and the airbag shrinks to a diameter smaller than the inner diameter of the container's 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 product from collapsing and wrinkling, and discharge excess water in the preformed wet embryo, so that the density and strength of the wet embryo are improved, and the heating energy consumption of the next process is reduced.

[0133] The guide column 131 is provided with a guide hole 133 (or not), the side wall of the guide column 131 is provided with an airflow channel 132 (the guide hole 133 and the airflow channel 132 may also be the same component), the airflow channel 132 may be a through groove, the inflation device and the air extraction device are connected to the inside of the airbag through the air pipe, the guide hole 133 and the airflow channel 132 in sequence (the inflation device and the air extraction device may be directly connected to the inside of the airbag through the air pipe and the airflow channel 132), and the inner edge of the port of the airbag is fixedly connected to the periphery of the guide column 131. Any connection method between the airbag and the guide column 131 is acceptable, as long as the airbag is sleeved outside the guide column 131.

[0134] The airflow channel 132 is used to store the airbag. The airbag is made of expandable material. When the vacuum device draws air into the airbag, the airbag shrinks into the airflow channel 132, and the diameter of the airbag wrapped around the 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 its natural state can be selected as much as possible to reduce the airbag expansion ratio and increase the service life of the airbag.

[0135] In some embodiments, Figures 11 to 13 As shown, a rectifier box 135 and a base 138 disposed at the bottom end of the rectifier box 135;

[0136] The interior of the rectifier box 135 is a hollow chamber 431, and the filling end of each expansion body 134 is connected to the hollow chamber 431 of the rectifier box 135. An air inlet nozzle and an air outlet nozzle are respectively arranged on the hollow chamber 431. The air inlet nozzle is externally connected to a device for filling recyclable objects, and the air outlet nozzle is externally connected to a vacuum device or air. The device for filling recyclable objects expands the expansion body 134, thereby squeezing the inner wall of the preformed wet embryo;

[0137] The upper end of the base 138 is provided with a limiting structure 139, and the base 138 is detachably connected to the rectifier box 135 through a quick lock structure. The limiting structure 139 is used to limit the left and right relative positions of the base 138 and the rectifier box 135 (the left and right directions here refer to the left and right directions as shown in FIG. Fig.13 A plurality of expansion bodies 134 are evenly distributed on the rectifier box 135, and the expansion bodies 134 are used to squeeze the inner wall of the product to be processed;

[0138] The recyclable object is preferably gas, and the expansion body 134 is preferably an air bag.

[0139] Specifically, a plurality of guide pillars 131 are evenly distributed on the rectifying box 135, and the feeding end of each guide pillar 131 is located inside the rectifying box 135 (it can also be directly connected to the rectifying box 135 by an air bag, and the guide pillar 131 is not provided), and an air inlet nozzle and an air outlet nozzle are respectively provided on the rectifying box 135, and the air inlet nozzle is externally connected to an inflation device, and the air outlet nozzle is externally connected to a vacuuming device or to the air (external atmospheric pressure). The rectifying box 135 is provided with multiple groups of guide pillars 131 to improve production efficiency. The rectifying box 135 is a diversion structure of multiple guide pillars 131 (or multiple air bags), and the air inlet nozzle on the rectifying box 135 is externally connected to an inflation device, and the air outlet nozzle of the rectifying box 135 is externally connected to a vacuuming device or to the air (external atmospheric pressure) to ensure that multiple air bags are simultaneously inhaled or exhausted.

[0140] In some embodiments, Fig.14 and Fig.15 As shown, a one-way speed regulating valve 137 is installed at the filling end of the expansion body 134, and the one-way speed regulating valve 137 is used to control the filling speed of the expansion body 134 with the recyclable object.

[0141] Specifically, a one-way speed regulating valve 137 is installed at the feeding end of each guide column 131, and the one-way speed regulating valve 137 is used to control the intake air flow rate of each guide column 131. If an airbag is damaged and leaks during production, without an explosion-proof structure, the remaining intact airbags will have insufficient air pressure, and the quality of the extruded product will be problematic. The one-way speed regulating valve 137 is set as the explosion-proof structure of the airbag. When an airbag ruptures, the one-way speed regulating valve 137 plays a role in making the flow rate of airflow through the damaged part much lower than the total intake flow rate, so it will not cause too much impact on other airbags, thereby ensuring that the remaining products can be produced normally.

[0142] The one-way speed regulating valve 137 is used to adjust the intake air flow rate of a single airbag so that the pressurized gas medium in the fairing box 135 can flow into each airbag evenly, and the one-way speed regulating valve 137 does not affect the air discharge of the airbag.

[0143] The cold pressing device for paper-plastic container products also includes a base 138. A limiting structure 139 and a quick lock structure are respectively arranged on the upper end of the base 138. The limiting structure 139 is used to limit the relative position of the rectifier box 135 and the base 138. The quick lock structure is used to fix the relative position of the base 138 and the rectifier box 135 to facilitate the staff to quickly install and disassemble the rectifier box 135, facilitate the positioning of the rectifier box 135, have high installation accuracy, and facilitate maintenance.

[0144] The limiting structure 139 includes two baffles 1310, and the two baffles 1310 are arranged relatively parallel, and the fairing box 135 is located between the two baffles 1310. Each baffle 1310 is detachably connected to the upper end of the base 138. One side of each baffle 1310 abuts against the outer wall of the fairing box 135. The gap between the two baffles 1310 is used to limit the relative position of the fairing box 135 on the base 138. When the fairing box 135 is inserted, the two baffles 1310 can play a guiding role, allowing it to smoothly enter the preset position. The gap between the two baffles 1310 can be adjusted to adapt to different fairing box 135 specifications.

[0145] A limiting groove 136 is provided on the outer wall of the rectifier box 135, one end of the stopper 1311 is located in the limiting groove 136, and a threaded hole is provided on the other end of the stopper 1311, in which an adjusting bolt is installed, and one end of the adjusting bolt abuts against the base 138 to adjust the front and rear relative position of the rectifier box 135 relative to the base 138, and the stopper 1311 and the baffle 1310 are arranged perpendicular to each other, and a through hole 416 is provided in the middle part of the stopper 1311, and one end of the fixing bolt passes through the through hole 416 and is fixedly connected to the base 138, and the two stops 1311 and the baffle 1310 respectively define the four sides of the rectifier box 135, which is convenient for positioning the rectifier box 135.

[0146] Compared with the positioning structure of the rectifier box 135 when the limiting structure 139 is used, the quick lock structure is used to quickly lock the relative position of the rectifier box 135 and the base 138. The quick lock structure includes a front top and a rear top. The front top includes a top pin 1312 and a spring 1313 arranged on its periphery, and the two ends of the spring 1313 are respectively fixedly connected to the periphery of the top pin 1312 and the upper end of the base 138. One end of the top pin 1312 is abutted against the front side of the rectifier box 135. The rear top includes a buckle 1314, and a slot is provided on the upper end of the base 138. The buckle One end of 1314 is snapped into the slot, and the other end of the buckle 1314 is fixedly connected to the outer wall of the rectifier box 135. The spring 1313 and the top pin 1312 are the tightening structure of the rectifier box 135. The rectifier box 135 is always subjected to the lateral tightening force of the top pin 1312 due to the elasticity of the spring 1313, so that one end of the buckle 1314 is snapped into the slot. When the rectifier box 135 needs to be disassembled, the staff compresses the spring 1313 and pulls up the rectifier box 135 at the end of the buckle 1314, and the rectifier box 135 can be removed as a whole.

[0147] In some embodiments, a cleaning unit and an air drying unit are provided on the inner wall of the second pulp tank of the pulp pool and / or on the outside of the pulp suction assembly;

[0148] The cleaning unit comprises a liquid spray nozzle, which is connected to a water source through a water supply pipeline, and sprays a spray to clean the periphery of the slurry suction component and / or the inner wall of the molding cavity;

[0149] The air drying unit comprises an air blowing nozzle, which is connected to compressed air through an air blowing pipeline. The air blowing nozzle blows air to dry the periphery of the slurry suction component and / or the inner wall of the molding cavity.

[0150] Specifically, in the present embodiment, the slurry pool is divided into two slurry tanks, that is, the slurry suction process and the cold pressing process are divided into two workstations for operation, thereby realizing dry-wet separation. At the same time, the outside of the molding chamber will be cleaned and air-dried when entering the cold pressing process. (It should be noted that in the present embodiment, in order to complete the cleaning and air-drying work, an air compression pipe and a high-pressure water pipe are arranged on the periphery of the cold pressing station. The pipe sprays water mist to clean the slurry suction component and then air-dry it. The air-drying here adopts the existing mature blowing nozzle, which is connected to compressed air. The cleaning and air-drying process is used to clean the residual slurry outside the cavity) to avoid excess slurry splashing and contaminating the subsequent workstations; the slurry pool is separated from the cold pressing to avoid the liquid from mixing into the slurry pool when cleaning the mold or the periphery of the chamber, thereby reducing the slurry pool concentration and affecting the product quality; after the airbag completes the cold pressing, 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.

[0151] 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 is transferred to the cold pressing station, opened to the specified angle and then dropped. The spray head arranged on one of the two side walls of the slurry pool in this embodiment can be driven by the transmission mechanism (it should be noted that the transmission mechanism described in this embodiment is a hydraulic rod driving the 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 move the spray head 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 rises and returns to the initial position, and the mold is closed.

[0152] At the same time, through the cleaning unit set inside the pulp pool, when the product processing is completed and the slurry inside the pulp pool is discharged, due to the characteristics of the slurry, a large amount of fiber will remain on the surface or bottom of the pulp pool, which needs to be cleaned manually. In the present invention, the cleaning unit set on the inner wall of the pulp tank 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 1 / 3 of the height of the pulp pool), liquid will flow out from the top of the pulp pool along the side wall of the pulp pool to help clean the inner wall of the pulp pool, and at the same time dilute the density of the slurry in the pulp pool, so that the fiber can be discharged better, reducing the labor intensity of personnel and improving work efficiency.

[0153] In the second aspect, based on the same concept, the embodiment of the present application further provides a plant fiber container wet embryo processing process, comprising:

[0154] A molding cavity 421 for forming a wet embryo of a plant fiber container;

[0155] The forming cavity 421 enters the slurry;

[0156] The opening of the molding cavity 421 faces downward;

[0157] The slurry enters the molding cavity through the cavity opening of the molding cavity 421, and the air in the molding cavity is discharged from the upper part of the molding cavity 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;

[0158] Preferably, when the molding cavity 421 enters the pulp pool, 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.

[0159] Alternatively, when the forming cavity 421 enters the pulp pool, 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 vacuum equipment. 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.

[0160] 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;

[0161] The expansion body 134 enters the molding cavity 421 through the cavity opening, squeezes the inner wall of the preformed wet blank, and completes the cold pressing.

[0162] Specifically, in this embodiment, the plant fiber container wet embryo processing technology includes a slurry absorption process and a cold pressing process.

[0163] Among them, during the slurry absorption process, vertical slurry absorption operation is adopted to help the wet embryo to be uniformly formed, and the phenomenon of slurry leakage will not occur. 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 expansion body 134 is used to expand and extrude the inner wall of the preformed wet embryo in the molding cavity 421 to discharge free water to obtain a molded wet embryo, thereby increasing the structural strength of the molded wet embryo, and improving the production quality and product qualification rate of the plant fiber container wet embryo, which greatly meets the market demand.

[0164] 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:

[0165] First, the opening of the forming cavity 421 may be arranged downward before entering the slurry pool.

[0166] 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.

[0167] 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.

[0168] The purpose of the several methods provided above is to ensure that the cavity opening of the molding cavity faces downward, and when the molding cavity is separated from the liquid surface, the excess slurry is discharged from the cavity opening of the molding cavity to ensure that the wall thickness of the container product is uniform.

This embodiment can meet the wall thickness, strength, density and other requirements of the product. When there are multiple cavities, it can meet the wall thickness, strength, density and other requirements of the specified area; 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 using the expansion body 134 to expand in the cold pressing process, the inner wall of the plant fiber container in the molding cavity 421 is squeezed to discharge free water to obtain the plant fiber container wet embryo, thereby increasing the structural strength of the molded wet embryo, improving the production quality and product qualification rate of the plant fiber container wet embryo, and greatly meeting the market demand.

[0186] In some embodiments, the slurry suction control strategy includes:

[0187] 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;

[0188] 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;

[0189] In response to the wet embryo stripping or 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 wet embryo stripping state are the states of the next process after the cold pressing process is completed.

[0190] 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.

The present embodiment does not specifically limit the electric control or pneumatic control method, that is, it is sufficient to complete the slurry suction, dehydration and stripping processes of the container product. Those skilled in the art can select a specific control method according to the actual site conditions. For the specific control means of each valve, refer to the following control method, which will not be repeated here.

[0192] 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 paper-plastic container in the slurry suction and dehydration processes.

[0193] 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.

[0207] 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 paper-plastic 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-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, thereby ensuring the consistency of the product, improving the product qualification rate of the paper-plastic container, and greatly meeting the market demand.
