Description

Technical Field

[0001] The invention belongs to the technical field of molding manufacturing, and in particular relates to a slurry absorbing device for molding plant fibers. Background Art

[0002] As the concept of green environmental protection gradually becomes a global consensus, product packaging designs that focus on "low carbon, reduced plastic, lightweight, and plant-based" have frequently appeared in the market, forming a green craze. The concept of environmentally friendly and sustainable packaging not only meets national strategic needs and policy orientations, but also reflects the brand's own value.

[0003] At present, in the field of green packaging, traditional equipment mostly adopts horizontal slurry absorption in the process of plant fiber molding slurry absorption, which can easily lead to uneven wall thickness of paper and plastic container products (commonly known as slurry pocketing). Since horizontal lifting will inevitably cause the upper part of the container to separate from the liquid surface first, 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 paper and plastic container will be discharged through the lower half of the container due to gravity. At the same time, plant fibers will accumulate in the lower half of the container, resulting in uneven side wall thickness between the upper and lower half of the paper and plastic container.

[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 poor fiber adsorption at the closed end, leading to problems such as thin and uneven wall thickness. Summary of the invention

[0056] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0057] See also Figure 1 , Figure 2 and Figure 6 As shown, this embodiment provides a plant fiber molding slurry suction device, the device comprising:

[0058] Slurry pool 1, frame assembly 2, transplanting mechanism 3 and slurry suction component;

[0059] The transplanting mechanism 3 is arranged on the frame assembly 2 and is located above the pulp pool 1;

[0060] The slurry suction assembly has a forming cavity 421 built therein, and the cavity opening of the forming cavity 421 is arranged toward the liquid surface of the slurry pool 1;

[0061] The slurry suction component and the liquid surface of the slurry pool 1 are moved relative to each other through the transplanting mechanism 3, so that the slurry suction component can go deep into or away from the liquid surface of the slurry pool 1, and the slurry in the slurry pool 1 enters the forming cavity 421 through the cavity opening to perform the slurry suction operation.

[0062] Here, the slurry suction component can be connected to an external control device and cooperate with the transplanting mechanism 3 to control the slurry suction device to perform and complete the slurry suction operation.

[0063] Specifically, in this 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 31 is driven to move up and down through the vertically arranged chain transmission, and the moving mechanism drives the slurry suction component to vertically penetrate into or move away from the liquid surface of the slurry pool 1. At the same time, the slurry suction operation of the slurry suction component is completed through the coordinated control of the external control device.

[0064] 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 pulp pool 1.

[0065] 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.

[0066] A plant fiber molding slurry suction device described in this embodiment controls the slurry suction component to vertically penetrate into or away from the liquid surface of the slurry pool 1 through the transplanting mechanism 3, and the cavity mouth of the molding cavity 421 is set toward the liquid surface of the slurry pool 1. When the slurry suction component is separated from the liquid surface of the slurry pool 1, excess slurry will flow out through the cavity mouth. This embodiment 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 point of the container product is increased, 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; at the same time, due to the vertical slurry suction method, when the molding cavity is separated from the liquid surface, excess slurry is discharged from the cavity mouth of the molding cavity, solving the problem of uneven wall thickness of the container product caused by horizontal slurry suction in traditional equipment, ensuring the uniform wall thickness of the container product, improving the product qualification rate of the container product, and greatly meeting market demand.

[0067] 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 has not improved it, so it will not be further described. The control system controls the movement of the transplanting mechanism 3 to enable the slurry suction component to penetrate into or move away from the liquid surface of the slurry pool 1 to complete the slurry suction operation.

[0068] In some embodiments, Figures 1 to 6 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.

[0069] 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.

[0070] 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.

[0071] In some embodiments, Figures 3 to 7 As shown, the molding die member 4 includes a molding assembly 41, a front end die 42 and a die back plate 43;

[0072] 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;

[0073] 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 .

[0074] 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 cavities 431 are connected to the molding cavity 421. Each cavity 431 is provided with one or more through holes 432. The through holes 432 are connected to external equipment through connecting pipes.

[0075] 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 mesh on the front end mold 42, and the filtered water enters the cavity 431 and is discharged through the connecting pipe, thereby realizing the pulp suction operation.

[0076] In some embodiments, the upper portion of the molding cavity 421 is connected to the external atmospheric pressure and / or is connected to a vacuum device; or;

[0077] The upper part of the cavity 431 is connected to the external atmospheric pressure and / or to a vacuum device.

[0078] Specifically, to ensure that the container product is completely formed, if it is not connected to the external atmospheric pressure, there will be gas in the cavity 431, the gas cannot be discharged, and the liquid cannot fill the entire cavity, so that the container 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 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 or exhausted, and the molding of the container product can also be achieved.

[0079] In some embodiments, Figures 6 to 9 As shown, the molding assembly 41 includes a mold base plate 411 and a mold backing plate 412;

[0080] 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;

[0081] 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 .

[0082] 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.

[0083] For further information, please refer to 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;

[0084] a plurality of fourth flow passage holes arranged along the second direction, with second gaps reserved between adjacent fourth flow passage holes;

[0085] The fourth flow-through hole is located below the third flow-through hole.

[0086] 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.

[0087] 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.

[0088] 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 paper-plastic container products with different structures, and has strong adaptability.

[0089] 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 paper-plastic 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.

[0090] In some embodiments, Figure 8 and Fig. 9 As shown, a plurality of internal fixing holes 415 are provided on the mold substrate 411;

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.

[0093] 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 position is selected based on the actual situation on site. In order to adapt to paper-plastic 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 12 are reserved. This is also related to the detachable connection between the mold pad 2 and the mold substrate 1 for easy replacement. If it is not this type of mold plate structure, the function of reserving all the internal fixing holes 12 cannot be achieved.

[0094] 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.

[0100] 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.

[0101] One end of the mold back plate 43 is provided with a limiting block 4111 corresponding to the positioning block 419 at the end away from the handle 4110;

[0102] 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;

[0104] 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.

[0110] 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 produce an extrusion pressure on the contact, and 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.

[0111] It should be noted that the elastic compression member 514 described in this embodiment is in the form of a spring, and the spring is sleeved on the connecting column 512, and the elastic force of the spring itself is used to realize the action of the locking block 516.

[0112] 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.

[0113] In some embodiments, Figures 3 to 5 As shown, 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;

[0114] The vacuum pipe 7 and the air pressure pipe 6 are provided with regulating units, which are not shown in the drawings, to control the flow and pressure inside the cavity 431 to perform the paper-plastic wet embryo forming action.

[0115] Specifically, the through hole 432 described in this embodiment corresponds to the external air compressor equipment and the vacuum equipment respectively through the independent air compressor pipe 6 and the vacuum pipe 7, and utilizes the regulating unit provided on the vacuum pipe 7 and the air compressor pipe 6. The regulating unit described in this embodiment is a control angle valve to adjust the flow and pressure inside the cavity 431, thereby completing the paper-plastic wet embryo forming operation.

[0116] It should be noted that in this embodiment, the method of regulating the flow and pressure inside the cavity 431 can be achieved through existing technical means (such as using the existing adjustment unit for controlling the horizontal slurry suction method). The content protected by this embodiment lies in the overall structure of the slurry suction device, which can complete the vertical slurry suction operation, and the specific flow and pressure control will not be elaborated.

[0117] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
