DETAILED DESCRIPTION

[0044] The specific implementation of the hot pressing forming device for bamboo pulp molded environmentally friendly tableware of the present invention will be further described below in conjunction with the accompanying drawings.

[0045] In the present embodiment, a bamboo pulp molded environmentally friendly tableware hot pressing forming device is mainly used for rapid molding, and there is no need to stop the operation during molding; the current tableware hot pressing forming device first adsorbs the molding from the bamboo pulp molding pool 1, and then performs a hot pressing treatment, and when the upper template is moved out of the bamboo pulp molding pool 1 for transfer, the bamboo pulp molding pool 1 needs to be shut down. It is necessary to wait for the upper template to heat the sample before it can be moved back to the top of the bamboo pulp molding pool 1 for the next round of processing, which will result in low processing efficiency and increased time cost. In the present embodiment, tableware can be produced continuously without stopping.

[0046] like Figure 1-Figure 10As shown, the tableware hot pressing forming device includes a frame 5, a forming assembly placed on the frame 5 along the left-right direction, a guide assembly arranged above the forming assembly and a plurality of groups of moving parts 3 that can move along the direction in which the guide assembly extends. The plurality of groups of moving parts 3 can move along the guide assembly so that the moldings on different moving parts 3 can be moved so that the machine can be operated continuously without stopping.

[0047] like Figure 1 As shown, the molding assembly includes a bamboo pulp molding pool 1, a hot pressing device 2 and a conveying mechanism 4 which are arranged in sequence from right to left. The guide assembly is arranged on the frame 5, and the guide assembly is located above the bamboo pulp molding pool 1, the hot pressing device 2 and the conveying mechanism 4. In this embodiment, a lower template which can extend up and down is provided in the bamboo pulp molding pool 1. After the bamboo pulp molding pool 1 is started, the liquid in the bamboo pulp molding pool 1 can be shaken evenly, and then the slurry is applied to the lower template, and then the slurry on the lower template is pumped off to form a molding on the lower template. After the molding is formed, it is moved to the hot pressing device 2 and adapted to the hot pressing device 2 to form the molding. The molding to be formed can be transported to the conveying mechanism 4 to transport the formed tableware to the next process.

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

[0049] The frame 5 includes a cabinet 501 for being placed on the ground, a plurality of support columns 502 fixed on the upper surface of the cabinet 501 and a top cover 503 fixed on 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 501. The guide assembly is installed on the side of the top cover 503 facing the cabinet 501, and the guide assembly can drive the moving part 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 fixing block 16 .

[0051] like Figure 2 , Figure 4-Figure 6 As shown, the guide assembly can drive multiple groups of moving parts 3 to move synchronously and intermittently, so that the moving parts 3 stop when they move to the top of the bamboo pulp forming tank 1, the hot pressing device 2 or the conveying mechanism 4.

[0052] Specifically, Figure 4 and Figure 5As shown, an annular retaining groove 8 is provided on the lower surface of the top cover 503, which is open in a downward direction and connected end to end. The annular retaining groove 8 is an inverted convex groove with its 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 movable part 3 moves to above the bamboo pulp molding pool 1, the hot pressing device 2 or the conveying mechanism 4, the first drive motor 703 stops driving. At this time, the second telescopic device 15 is started to limit the movable part 3 above the bamboo pulp molding pool 1, the hot pressing device 2 or the conveying mechanism 4 to avoid deviation between the upper mold 12 and the bamboo pulp molding pool 1, the hot pressing device 2 or the conveying mechanism 4.

[0061] Specifically, a second telescopic device 15 extending in the front-to-back direction is provided in the top cover 503; after the second telescopic device 15 is started, it can drive the hinged plate 18 to swing, thereby driving the cross bar 17 to rotate, and two fixed blocks 16 arranged at intervals on the left and right are fixedly provided on the rear side of the top cover 503, and a cross bar 17 is rotatably provided between the two fixed blocks 16, and a hinged plate 18 is fixedly sleeved on the cross bar 17, and the hinged plate 18 is hingedly connected to the end of the movable rod of the second telescopic device 15; three sets of swinging plates 19 that can rotate with the cross bar 17 are fixedly sleeved on the cross bar 17, and each swinging plate 19 is fixedly provided at the bottom There are clamping columns 20, and three groups of clamping columns 20 are respectively located directly above the bamboo pulp forming pool 1, the hot pressing device 2 and the conveying mechanism 4. The movable part 3 is provided with a clamping groove for the clamping column 20 to be inserted. When the cross bar 17 rotates, the clamping column 20 can be driven to rotate through the swing plate 19, so that the clamping column 20 is clamped in the clamping groove to limit the corresponding movable part 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 column 20 to limit the movable part 3 above the bamboo pulp forming pool 1, the hot pressing device 2 or the conveying mechanism 4.

[0062] like Fig. 9 and Fig.10 As shown, when the moving member 3 carrying the hot-pressed tableware moves to the top of the conveyor belt 401, the formed tableware can be demoulded through the demoulding structure to achieve the purpose of convenient demoulding.

[0063] Specifically, a downwardly opening square sliding groove is provided 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 is retracted 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 is extended from the sliding groove, the molding adhered to the lower surface of the demolding member 13 can be detached.

[0064] Specifically, the demolding structure includes a second drive motor 1401 fixed on the movable part 3 and a lead screw 1402 which is transmission-connected to the output end of the second drive motor 1401 and is vertically arranged; the lead screw 1402 is located in the sliding groove, and the demolding part 13 is threadedly mounted on the lead screw 1402. When the second drive motor 1401 is started, it can drive the lead screw 1402 to rotate, so that the demolding part 13 moves downward along the sliding groove.

[0065] Working principle: The first driving motor 703 is started, so that one of the sprocket wheels 701 can be driven to rotate. Since the chain 702 is wound around the two sprocket wheels 701, the other sprocket wheel 701 can be driven to rotate, so that the chain 702 drives multiple groups of moving parts 3 to move, so that different moving parts 3 can move to the top of the bamboo pulp forming pool 1, the hot pressing device 2 and the conveying mechanism 4, and the vertical telescopic device 6 is driven to start, so that the upper mold 12 can move downward to adapt to the bamboo pulp forming pool 1, the hot pressing device 2 or the conveying mechanism 4 (the moving part 3 located above the bamboo pulp forming pool 1 can move the lower template on the lower template The molding is adsorbed on the upper mold 12; the moving part 3 located above the hot pressing device 2 can adapt the upper mold 12 adsorbing the molding to the hot pressing device 2, and perform hot pressing molding on the molding; the moving part 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 keep driving different moving parts 3 to move, so that during the hot pressing operation, the bamboo pulp molding pool 1 can also be operated without stopping the machine, and the molding can also be hot pressed and bamboo pulp molding operations while the conveying mechanism 4 is operating.

[0066] When the third driving 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 the tableware placed on the conveyor belt 401.

[0067] When the movable part 3 moves to above the bamboo pulp forming pool 1, the hot pressing device 2 or the conveying mechanism 4, after the second telescopic device 15 is started, it can drive the hinged 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 movable part 3.

[0068] When the upper mold 12 located above the conveyor belt 401 needs to be demolded, the second drive motor 1401 is started, which can drive the lead screw 1402 to rotate, so that the demolding part 13 moves downward along the sliding groove, and the molding adhered to the lower surface of the demolding part 13 is separated. When the demolding part 13 is retracted into the sliding groove, the lower surface of the demolding part 13 is flush with the lower surface of the upper mold 12, so as to facilitate the next demolding.

[0069] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. The basic concept of the present invention is that the chain 702 connected end to end can drive the multiple groups of moving parts 3 on the chain 702 to move, so as to achieve the purpose of molding in the bamboo pulp molding pool 1, hot pressing the molding, and transporting the hot-pressed tableware to the next process.
