Description

Technical Field

[0001] The present invention relates to the technical field of bamboo pulp tableware, and specifically to a hot pressing and forming device for environmentally friendly bamboo pulp molded tableware. Background Art

[0002] Disposable tableware is a daily necessity in people's lives, mainly made of petrochemical-based plastics. While bringing convenience to human life, disposable plastic tableware causes serious pollution to the global environment. In addition, microplastic particles can enter the animal body again through the food chain and cannot be metabolized normally, causing damage to the cardiovascular system, liver, and infants in the pregnant woman's body.

[0003] The patent with the publication number CN118910940A discloses a hot pressing and forming device for bamboo pulp molded tableware. The present invention proposes the following scheme, including a tooling bottom plate, on the upper side of which a tooling frame is connected by bolts, and on the tooling frame, a forming platform is connected by bolts. A fixing module is arranged on the forming platform, and the fixing module includes a abutment seat. When different-shaped tableware needs to be produced, the mold can be quickly disassembled and changed according to the customer's needs, reducing the cost of replacing the device, which is beneficial to the daily production needs of the manufacturer; the patent with the publication number CN218365362U discloses a hot pressing module of an environmentally friendly tableware hot pressing machine. The present utility model includes a first die base and a second die base which are respectively used to support two lower templates and are arranged opposite to each other up and down; it also includes a hot pressing head arranged above the first die base, a buffer assembly for providing a buffer force for the first die base and the second die base, and a moving assembly for moving the first die base and the second die base away directly below the hot pressing head; mounting positions for installing the upper template are arranged at the bottoms of both the hot pressing head and the first die base. By installing the lower template on the first die base and the second die base, and installing the upper template at the bottoms of the first die base and the hot pressing head, two batches of products can be processed simultaneously at one station. The buffer assembly can prevent hard collisions between the first die base and the second die base, and the moving assembly facilitates feeding and discharging.

[0004] Although the above patents can achieve convenient replacement between molds and can process two batches of products simultaneously at one station, there are still the following deficiencies: When hot pressing and forming bamboo pulp tableware, it is necessary to first homogenize the pulp in the bamboo pulp forming pool, then apply the pulp to the lower template, and then pump out the pulp on the lower template. After that, the upper template moves down to fit with the lower template for pressurized forming. After forming, the upper template moves with the sample and stops above the heating device, and then moves down to fit with the heating device for heating. After heating is completed, the production is finished. However, there are problems with the hot pressing machines on the market. When the upper template moves out of the bamboo pulp forming pool for transfer, the bamboo pulp forming pool stops, and it has to wait for the upper template to heat the sample before it can move back above the frame for the next round of processing, which results in low processing efficiency and increased time costs. Summary of the Invention

Detailed implementation manners

[0044] The following further describes the detailed implementation manners of a hot pressing and forming device for bamboo pulp molded environmental protection tableware of the present invention with reference to the accompanying drawings.

[0045] In this embodiment, a hot pressing and forming device for bamboo pulp molded environmental protection tableware is mainly used for molding that can be quickly formed without stopping during the forming process; for the current tableware hot pressing and forming device, the molding is first adsorbed from the bamboo pulp forming pool 1 and then hot pressed. When the upper template is transferred out of the bamboo pulp forming pool 1, the bamboo pulp forming pool 1 needs to stop, and it can only be moved back above the bamboo pulp forming pool 1 for the next round of processing after the upper template heats the sample, which will result in low processing efficiency and increased time cost. In this embodiment, the production of tableware can be continuously carried out without stopping.

[0046] Such as Figures 1 - 10As shown in the figure, the tableware hot pressing and forming device includes a frame 5, a forming assembly arranged on the frame 5 in the left-right direction, a guiding assembly arranged above the forming assembly, and multiple moving members 3 capable of moving along the extending direction of the guiding assembly. The multiple moving members 3 can move along the guiding assembly, enabling the molds on different moving members 3 to move, so that continuous operation can be carried out without stopping the machine.

[0047] As Figure 1 shown in the figure, the forming assembly includes a bamboo pulp forming pool 1, a hot pressing device 2, and a conveying mechanism 4 arranged in sequence from right to left. The guiding assembly is arranged on the frame 5 and is located above the bamboo pulp forming pool 1, the hot pressing device 2, and the conveying mechanism 4. In this embodiment, a lower template capable of extending up and down is arranged in the bamboo pulp forming pool 1. After the bamboo pulp forming pool 1 is started, the liquid in the bamboo pulp forming pool 1 can be shaken evenly, and then slurry is applied to the lower template. Subsequently, the slurry on the lower template is pumped out to form a mold on the lower template. After the mold is formed, it is moved to the hot pressing device 2 and adapted to the hot pressing device 2 to form the mold. The mold to be formed can then be transported to the conveying mechanism 4 to convey the formed tableware to the next process.

[0048] In this embodiment, the structures and principles of the bamboo pulp forming pool 1, the hot pressing device 2, and the conveying mechanism 4 are all prior arts and will not be elaborated in detail here.

[0049] The frame 5 includes a cabinet body 501 for placing on the ground, multiple support columns 502 fixedly arranged on the upper surface of the cabinet body 501, and a top cover 503 fixedly arranged at the upper ends of the support columns 502. The bamboo pulp forming pool 1, the hot pressing device 2, and the conveying mechanism 4 are all arranged on the cabinet body 501. The guiding assembly is installed on the side of the top cover 503 facing the cabinet body 501, and the guiding assembly can drive the moving members 3 to move.

[0050] In this embodiment, two of the support columns 502 are fixedly connected to the top rod 503, and the other two support columns 502 are fixedly connected to the fixed block 16.

[0051] As Figure 2 、 Figures 4 - 6 shown in the figure, the guiding assembly can drive the multiple moving members 3 to move synchronously and intermittently, and stop when the moving members 3 move directly above the bamboo pulp forming pool 1, the hot pressing device 2, or the conveying mechanism 4.

[0052] Specifically, as Figure 4 and Figure 5As shown, an annular retaining groove 8 with an opening facing downward and connected end to end is provided on the lower surface of the top cover 503. The annular retaining groove 8 is an inverted convex groove with an opening facing downward. The setting of the annular retaining groove 8 ensures that the chain 702 will not fall off when it rotates under the action of the sprocket 701. In this embodiment, the annular retaining groove 8 includes a limit groove and baffles fixed on the upper and lower sides of the limit groove, and the baffles are used to prevent the chain 702 from falling off.

[0053] The guide assembly includes two sprockets 701 rotatably arranged on the side of the top cover 503 facing the cabinet body 501 and a chain 702 wound around the two sprockets 701; a first drive motor 703 is fixedly arranged on the upper surface of the top cover 503, and the first drive motor 703 is transmission-connected to one of the sprockets 701 so that the chain 702 can move along the annular retaining groove 8. When the first drive motor 703 is started, it can drive one of the sprockets 701 to rotate. Since the chain 702 is wound around the two sprockets 701, it can drive the other sprocket 701 to rotate.

[0054] The moving part 3 is assembled on the chain 702 so that when the chain 702 rotates, it can drive the moving part 3 to move. In this embodiment, there is an interface on the moving part 3 that matches the chain 702. This interface can be a groove, a protrusion or other form of connecting structure to cooperate with the corresponding part on the chain 702. The structure and principle of the connection between the moving part 3 and the chain 702 are existing technologies and will not be described in detail here.

[0055] like Figure 4 As shown, when the movable part 3 moves to above the bamboo pulp forming tank 1, the hot pressing device 2 and the conveying mechanism 4, the upper mold 12 can be driven downward by the vertical telescopic device 6 to cooperate with the bamboo pulp forming tank 1, the hot pressing device 2 or the conveying mechanism 4.

[0056] Specifically, each movable part 3 is fixed with a vertical telescopic device 6 extending in the up and down direction, and the upper mold 12 is fixed at the end of the movable rod of the vertical telescopic device 6 to drive multiple groups of upper molds 12 to move downward at the same time and adapt to the bamboo pulp molding pool 1, the hot pressing device 2 and the conveying mechanism 4. After the vertical telescopic device 6 is started, the upper mold 12 can move downward to adapt to the lower template in the bamboo pulp molding pool 1, and the molding is adsorbed on the upper mold 12, and the upper mold 12 adsorbs the molding and adapts to the hot pressing device 2, so that the molding can be hot-pressed, and the hot-pressed tableware can be placed on the conveying mechanism 4 and transported to the next process.

[0057] like Figure 3As shown, the conveying mechanism 4 includes a conveyor belt 401, a third drive motor 402 and two rollers 403; the conveyor belt 401 is wound around two discharging rollers 403, and the third drive motor 402 is connected to one of the rollers 403 by transmission. When the third drive motor 402 is started, it can drive one of the rollers 403 to rotate. Since the conveyor belt 401 is wound around the two rollers 403, it can drive the conveyor belt 401 to transmit, so as to transport the tableware placed on the conveyor belt 401.

[0058] The conveyor belt 401 is located at one side of the hot pressing device 2 and above the cabinet 501 . When the moving parts 3 stop, the conveyor belt 401 is located directly below one of the moving parts 3 . The conveyor belt 401 can catch the tableware dropped from the upper mold 12 .

[0059] like Figure 4 As shown, a limit rail 9 connected end to end is fixedly provided at the lower end of the top cover 503, and the limit rail 9 is an "I"-shaped structure. The setting of the limit rail 9 enables the roller 11 to roll against the limit rail 9, which can improve the suspension capacity of the movable part 3, so as to improve the stability of the connection between the movable part 3 and the chain 702, and avoid the chain 702 or the movable part 3 from tilting or falling off. A mounting seat 10 is fixedly installed on each movable part 3, and a roller 11 adapted to the limit rail 9 is provided on the mounting seat 10, so that when the movable part 3 moves, the roller 11 can move in the limit rail 9, and when the movable part 3 moves under the action of the chain 702, the roller 11 on the movable part 3 can also move along the limit rail 9.

[0060] like Figure 3 As shown, when the moving member 3 moves to the top of the bamboo pulp forming tank 1, the hot pressing device 2 or the conveying mechanism 4,

[0061] The first driving motor 703 stops driving, and at this time, the second telescopic device 15 starts to limit the movable part 3 above the bamboo pulp molding tank 1, the hot pressing device 2 or the conveying mechanism 4 to avoid deviation between the upper mold 12 and the bamboo pulp molding tank 1, the hot pressing device 2 or the conveying mechanism 4.

[0062] Specifically, a second telescopic device 15 extending in the front-back direction is provided inside the top cover 503; after the second telescopic device 15 is activated, it can drive the hinge plate 18 to swing, and then drive the cross bar 17 to rotate. Two fixed blocks 16 are fixedly provided at the rear side of the top cover 503 and are arranged at intervals left and right. The cross bar 17 is rotatably provided between the two fixed blocks 16. An articulated plate 18 is fixedly sleeved on the cross bar 17, and the articulated plate 18 is hinged to the end of the movable rod of the second telescopic device 15; three swing plates 19 that can rotate with the cross bar 17 are fixedly sleeved on the cross bar 17. A clamping post 20 is fixedly provided below each swing plate 19. The three clamping posts 20 are respectively located directly above the bamboo pulp forming pool 1, the hot pressing device 2, and the conveying mechanism 4. The moving member 3 is provided with a clamping groove for the clamping post 20 to be inserted. When the cross bar 17 rotates, it can drive the clamping post 20 to rotate through the swing plate 19, so that the clamping post 20 is clamped in the clamping groove to limit the corresponding moving member 3. When the swing plate 19 swings under the action of the second telescopic device 15, it can be adapted to the clamping groove through the clamping post 20 to limit the moving member 3 above the bamboo pulp forming pool 1, the hot pressing device 2, or the conveying mechanism 4.

[0063] As Figure 9 and Figure 10 shown, when the moving member 3 carries the tableware after hot pressing and moves to directly above the conveyor belt 401, it can demold the formed tableware through the demolding structure to achieve the purpose of convenient demolding.

[0064] Specifically, a sliding groove with a downward opening and a square shape is opened at the lower end of the upper mold 12. A demolding structure is provided in the sliding groove, and the demolding structure is connected to a demolding member 13, so that the demolding member 13 can move up and down along the sliding groove. When the demolding member 13 retracts into the sliding groove, the lower surface of the demolding member 13 is flush with the lower surface of the upper mold 12. When the demolding member 13 extends out of the sliding groove, it can separate the molding adhered to the lower surface of the demolding member 13.

[0065] Specifically, the demolding structure includes a second driving motor 1401 fixedly provided on the upper mold 12 and a lead screw 1402 vertically arranged and drivingly connected to the output end of the second driving motor 1401; the lead screw 1402 is located in the sliding groove, and the demolding member 13 is threadedly sleeved on the lead screw 1402. When the second driving motor 1401 is started, it can drive the lead screw 1402 to rotate, so that the demolding member 13 moves downward along the sliding groove.

[0066] Working principle: The first driving motor 703 starts, enabling one of the sprockets 701 to rotate. Since the chain 702 is wound around the two sprockets 701, the other sprocket 701 can be driven to rotate, causing the chain 702 to drive multiple moving members 3 to move, enabling different moving members 3 to move above the bamboo pulp forming pool 1, the hot pressing device 2, and the conveying mechanism 4. The vertical telescopic device 6 is driven to start, enabling the upper mold 12 to move downward to adapt to the bamboo pulp forming pool 1, the hot pressing device 2, or the conveying mechanism 4 (the moving member 3 located above the bamboo pulp forming pool 1 can adsorb the molding on the lower template onto the upper mold 12; the moving member 3 located above the hot pressing device 2 can adapt the upper mold 12 with the adsorbed molding to the hot pressing device 2 to perform hot pressing on the molding; the moving member 3 located above the conveying mechanism 4 can place the hot-pressed tableware on the conveyor belt 401 and convey it to the next process); after completion, the chain 702 can continuously drive different moving members 3 to move, enabling operations to be carried out in the bamboo pulp forming pool 1 during hot pressing without the need for shutdown operations, and enabling hot pressing and bamboo pulp forming operations on the molding while the conveying mechanism 4 is operating.

[0067] The third driving motor 402 starts, enabling one of the rollers 403 to rotate. Since the conveyor belt 401 is wound around the two rollers 403, the conveyor belt 401 can be driven to convey, so as to convey the tableware placed on the conveyor belt 401.

[0068] When the moving member 3 moves above the bamboo pulp forming pool 1, the hot pressing device 2, or the conveying mechanism 4, after the second telescopic device 15 starts, it can drive the hinge plate 18 to swing, and then drive the cross bar 17 to rotate. When the cross bar 17 rotates, it can drive the clamping column 20 to rotate through the swing plate 19, so that the clamping column 20 is clamped in the clamping groove to limit the corresponding moving member 3.

[0069] When the upper mold 12 located above the conveyor belt 401 needs to be demolded, the second driving motor 1401 starts, enabling the lead screw 1402 to rotate, causing the demolding member 13 to move downward along the sliding groove to separate the molding adhered to the lower surface of the demolding member 13. When the demolding member 13 retracts into the sliding groove, the lower surface of the demolding member 13 is flush with the lower surface of the upper mold 12 for the next demolding.

[0070] The above-described embodiments of the present invention do not constitute a limitation to the protection scope of the present invention. The basic concept of the present invention is that through the chain 702 connected end to end, multiple sets of moving parts 3 on the chain 702 can be driven to move, so as to achieve the purpose of both performing molding in the bamboo pulp forming pool 1, simultaneously performing hot pressing on the molding, and further conveying the tableware after hot pressing to the next process. It can operate synchronously without stopping, improving production efficiency. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
