Description

Technical Field

[0001] This invention relates to the field of molded product processing technology, specifically to a method for transferring plant fiber molded products and a molding apparatus. Background Technology

[0002] Paper tableware is not only environmentally friendly but also biodegradable and commonly used in daily life. During production, paper pulp is first made into a wet blank, which is then transported to a mold and hot-pressed into shape. After being hot-pressed into a dry blank, excess waste is removed using a trimming device. A robotic arm then transfers the finished product from the trimming device, and the pieces are stacked sequentially.

[0003] The current processing steps for paper tableware are numerous and the coordination between them is inefficient, resulting in low output efficiency of finished products. The current processing setup involves multiple hot pressing stations to form wet blanks into dry blanks. Because the dry blank forming time is long, the waiting time for wet blanks to be processed is also long, which affects the dry blank forming process.

A connecting plate is installed at the output end of the cylinder of each mesh frame lifting device. A pair of snap-fit ​​devices are fixedly installed on the inner side of the connecting plate, and a mesh frame is installed in the connecting structure. The top of the top plate is fixedly connected to... The machine includes an extrusion transfer mold drive device. A movable extrusion transfer mold mounting plate is fixedly connected to the output end of the drive device. An extrusion transfer mold is mounted on the lower surface of the movable extrusion transfer mold mounting plate. A high-level slurry supply tank is fixedly connected above the top plate of the machine body. A slurry supply pipe is connected to the output end of the high-level slurry supply tank. The slurry supply pipe is connected to the inlet end of the slurry supply device. The outlet end of the slurry supply device is connected to the grouting port. The bottom of the grouting port is connected to the pipe opening of a slurry recovery and utilization device. The pipe opening of the slurry recovery and utilization device serves as the inlet and outlet ports of a residual slurry storage tank. A slurry recovery and utilization drive device is installed at the other end of the residual slurry storage tank.

[0008] As a preferred embodiment of the present invention, the bottom of the slurry supply pipe is connected to a residual slurry storage tank located inside the frame, and the bottom of the residual slurry storage tank is connected to a slurry recovery drive device.

[0009] As a preferred embodiment of the present invention, the connection structure includes a telescopic cylinder fixedly connected to the surface of the connecting plate, and the output end of the telescopic cylinder is fixedly connected to a buckle, which can be snapped onto the surface of the mesh frame.

[0010] As a preferred embodiment of the present invention, buffer support rods are fixedly connected to the four corners of the bottom of the transmission plate, a positioning drive device is fixedly connected to the top of the frame, a positioning plate is fixedly connected to the output end of the positioning drive device, the positioning drive device can push the positioning plate to move horizontally, and holes are opened on the surface of the positioning plate.

[0011] As a preferred embodiment of the present invention, a positioning mold drive is fixedly connected to the top of the frame, and the mesh-to-transfer positioning mold is fixedly connected to the surface of the positioning mold drive. The positioning mold drive can push the mesh-to-transfer positioning mold to move between the extrusion transfer mold and the slurry tank.

[0012] As a preferred embodiment of the present invention, a mold washing drive cylinder is fixedly connected to the top of the frame, and a cleaning rod located inside the slurry tank is fixedly connected to the output end of the mold washing drive cylinder, and the cleaning rod is connected to an external water source.

[0014] A method and apparatus for transferring plant fiber molded articles, comprising the following steps:

[0015] S1: The slurry recycling drive device pushes the slurry from the residual slurry storage tank into the slurry pool for use. Then, the high-level slurry supply tank controls the slurry supply device through the slurry supply pipeline to inject the slurry into the slurry pool. After the slurry is injected, the vacuum suction of the slurry in the suction mold begins to form a wet blank. After the suction is completed, the excess slurry is pumped into the residual slurry storage tank by the recycling drive device for storage, waiting for the next recycling. At this time, the extrusion transfer mold drive device pushes the extrusion transfer mold down to close with the suction mold and perform parallel extrusion. After extrusion, the wet blank is transferred to the extrusion transfer mold.

[0016] S2: When the two are connected, the extrusion transfer mold carries the wet blank upward, and the empty mesh frame is placed in the mesh-to-transfer transfer positioning mold and enters the intermediate position together. The positioning drive device drives the positioning plate to move, and the holes on the positioning plate are vertically misaligned with the buffer support rod. Then the extrusion transfer mold descends to the intermediate position and closes with the mesh-to-transfer transfer positioning mold to perform extrusion. When the extrusion is in place, the buffer support rod hits the positioning plate to play a buffering role. That is, after the extrusion is in place, the mesh-to-transfer transfer positioning mold is protected from the extrusion force. After extrusion, the wet blank is transferred to the empty mesh frame of the mesh-to-transfer transfer positioning mold. After the wet blank is transferred to the mesh frame, the extrusion transfer mold rises and returns. The positioning drive device drives the positioning plate to move and return to the initial position, so that the holes on the positioning plate and the buffer support rod are reset vertically, so that the two are in the center position.

[0017] S3: The external robotic arm enters the machine body. After the robotic arm is in place, the frame lifting device descends and grabs the empty frame on the robotic arm onto the connecting structure. Then, the frame lifting device drives the empty frame on the connecting structure to rise back to the original high position. Then, the frame with wet blank is grabbed onto the external robotic arm. The robotic arm carries the wet blank frame back and removes it from the molding machine. Finally, the connecting structure drives the empty frame to descend. When it reaches the intermediate transition position, the buckle is opened and the empty frame is placed into the frame transfer transition positioning mold. After the empty frame is placed into the frame transfer transition positioning mold, the connecting structure rises and returns to the original position. The frame transfer transition positioning mold with the empty frame exits and returns to the starting position outside the frame, completing one cycle of wet blank transfer.

[0018] S4: After the wet preform transfer is completed and the extrusion transfer die rises back to its original position, the mesh transfer transition positioning die moving device moves within the frame. At the same time, the washing die drive cylinder pushes the washing rod forward a certain distance to open the control water valve and start washing. Before the washing rod returns to its original position, the water valve is closed, the control water valve is closed, washing stops, and the rod continues to return to its original position. The drive stops, completing one cycle of washing.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. This invention can improve the processing efficiency of plant fiber molded products, enabling automatic loading and unloading operations. Furthermore, by setting up a residual slurry storage tank, it can prevent excessive slurry loading, improving the product qualification rate. The telescopic cylinder and buckle improve the stability of the equipment connection, allowing for multiple cycles of use. The buffer support rod and positioning drive device can support the mesh-to-transfer positioning mold, preventing excessive compression. The cleaning rod and mold-washing drive cylinder can automatically flush the slurry pool, preventing slurry adhesion and accumulation. Therefore, this invention can automate product processing, resulting in high product output efficiency and quality, and enabling sustainable product processing. Attached Figure Description

[0034] refer to Figure 2 Both sides of the top of the frame 1 are fixedly connected to positioning mold tracks 27 located outside the slurry tank 2, and the positioning mold tracks 27 are slidably connected to the mesh transfer positioning mold 9.

[0035] refer to Figure 1 A method and apparatus for transferring plant fiber molded products, comprising the following steps:

[0036] S1: After the slurry recycling drive device 17 pushes the slurry from the residual slurry storage tank into the slurry pool for use, the high-level slurry supply tank 6 controls the slurry supply device through the slurry supply pipe 7 to inject the slurry into the slurry pool 2. After the slurry is injected, the vacuum suction of the slurry in the suction mold is started to form a wet blank. After the suction is completed, the excess slurry is pumped into the residual slurry storage tank 16 by the recycling drive device 17 for storage, waiting for the next recycling. At this time, the extrusion transfer mold drive device 14 pushes the extrusion transfer mold 13 down and closes with the suction mold 4 to perform parallel extrusion. After extrusion, the wet blank is transferred to the extrusion transfer mold (13).

[0037] S2: When the two are connected, the extrusion transfer mold 13 carries the wet blank upward, and the empty mesh frame 12 is placed in the mesh-to-transfer transfer positioning mold 9 and enters the transfer position together. The positioning drive device 21 drives the positioning plate 22 to move, and the hole 23 on the positioning plate 22 is vertically misaligned with the buffer support rod 20. Then the extrusion transfer mold 13 descends to the transfer position and closes with the mesh-to-transfer transfer positioning mold 9 to extrude. When the extrusion is in place, the buffer support rod 20 pushes against the positioning plate 22 to play a buffering role. That is, after the extrusion is in place, the mesh-to-transfer transfer positioning mold 9 is protected from the extrusion force. After the extrusion, the wet blank is transferred to the empty mesh frame 12 of the mesh-to-transfer transfer positioning mold 9. After the wet blank is transferred to the mesh frame 12, the extrusion transfer mold 13 rises and returns. The positioning drive device 21 drives the positioning plate 22 to move and return to the initial position, so that the hole 23 on the positioning plate 22 and the buffer support rod 20 are vertically reset so that the two are in the center position.

[0038] S3: The external robotic arm enters the machine body and enters the position. The frame lifting device 10 descends, and the latch telescopic device (such as a cylinder or electromagnet) 18 extends and latches the empty frame 12 on the robotic arm. The frame lifting device 10 then raises and returns with the empty frame 12. The external robotic arm then picks up the wet frame 12 and moves it back to the robotic arm. The robotic arm then moves the wet frame 12 back out of the molding machine. Finally, the frame lifting device 10 drives the connecting structure to lower the empty frame 12. When it reaches the intermediate transition position, the latch telescopic device 18 (such as a cylinder or electromagnet) retracts and opens the latch 19, allowing the empty frame 12 to fall into the frame transition positioning mold 9. After the empty frame 12 falls into the frame transition positioning mold 9, the frame lifting device 10 drives the connecting structure to rise and return to the original position. The frame transition positioning mold 9 then exits with the empty frame 12 and returns to the starting position outside the frame 1, completing one wet frame transfer cycle.

[0039] S4: After the wet preform transfer is completed and the extrusion transfer die rises back to its original position, the mesh transfer transition positioning die moving device 24 moves within the frame. At the same time, the washing die drive cylinder 25 pushes the washing rod 26 forward a certain distance to open the control water valve and start washing. Before the washing rod 26 returns to its original position, the water valve is closed, the control water valve is closed, the washing stops, and the rod continues to return to its original position. The drive stops, completing one cycle of washing.

[0040] The working principle and usage process of this invention are as follows: During use, the slurry recycling drive device 17 recycles the slurry from the residual slurry storage tank and pushes it back into the slurry pool 2 for reuse. The high-level slurry supply tank 6 controls the slurry supply device to inject slurry into the slurry pool 2 through the slurry supply pipe 7. After the slurry is injected, vacuum suction begins to form a wet blank from the slurry suction mold 4. After suction, excess slurry is pumped into the residual slurry storage tank 16 by the recycling drive device 17 for storage, awaiting the next recycling. At this time, the extrusion transfer mold drive device 14 pushes the extrusion transfer mold 13 down to close with the suction mold 4 for parallel extrusion. After extrusion, the wet blank is transferred to the extrusion transfer mold 13. When the two are connected, the extrusion transfer mold 13 carries the wet blank... The blank rises, and the empty mesh frame 12 is placed in the mesh transition transfer positioning mold 9, entering the intermediate position together. The positioning drive device 21 drives the positioning plate 22 to move, vertically misaligning the hole 23 on the positioning plate 22 with the buffer support rod 20. Then, the extrusion transfer mold 13 descends to the intermediate position and closes with the mesh transition transfer positioning mold 9 for extrusion. When the extrusion is in place, the buffer support rod 20 pushes against the positioning plate 22 to provide a buffering effect, protecting the mesh transition transfer positioning mold 9 from the extrusion force. After extrusion, the wet blank is transferred to the empty mesh frame 12 of the mesh transition transfer positioning mold 9. After the wet blank is transferred to the mesh frame 12, the extrusion transfer mold 13 rises back, and the positioning drive device 21... The drive positioning plate 22 moves back to the initial position, the external robot enters the machine body, and the robot enters the position. The wire mesh frame lifting device 10 descends, and the latch telescopic device (such as a cylinder or electromagnet) 18 extends the latch 19 to clamp the empty wire mesh frame 12 on the robot. Then, the wire mesh frame lifting device 10 takes the empty wire mesh frame 12 up and returns. Then, the external robot grabs the wire mesh frame 12 with the wet blank onto the robot. The robot takes the wet blank wire mesh frame 12 back and removes it from the molding machine. Finally, the wire mesh frame lifting device 10 drives the connecting structure to lower the empty wire mesh frame (12). When it reaches the intermediate transition position, the latch telescopic device (18) (such as a cylinder or electromagnet) retracts, opens the latch 19, and the empty wire mesh frame 12 is placed on the wire mesh transition positioning mold. In step 9, after the empty mesh frame 12 is placed onto the mesh transfer transition positioning mold 9, the mesh frame lifting device (10) drives the connecting structure to rise and return to the original position. The mesh transfer transition positioning mold 9, along with the empty mesh frame 12, exits and returns to the starting position outside the frame 1, completing one cycle of wet blank transfer. After the wet blank transfer is completed, the extrusion transfer mold 13 rises and returns to the original position. During the movement of the mesh transfer transition positioning mold moving device 24 within the frame 1, the mold washing drive cylinder 25 pushes the washing rod 26 forward a certain distance to open the control water valve and start washing. Before the washing rod 26 returns to the position, the water valve is closed, the control water valve is closed, the washing stops, and the rod continues to return to the position. The drive stops, completing one cycle of washing.

[0041] In summary, this plant fiber molded product transfer method and molding device can improve the processing efficiency of plant fiber molded products, enabling automatic loading and unloading operations. Furthermore, by setting up a residual slurry storage tank 16, excessive slurry loading can be prevented, improving the product processing qualification rate. The telescopic cylinder 18 and the buckle 19 can improve the stability of the equipment connection, allowing for multiple cycles of use. The buffer support rod 20 and the positioning drive device 21 can support the mesh-to-transfer positioning mold 9, preventing it from being excessively compressed. The cleaning rod 26 and the mold washing drive cylinder 25 can automatically flush the slurry pool 2, preventing slurry adhesion and accumulation. Therefore, this invention can automate product processing, resulting in high product output efficiency and quality, and allows for sustainable product processing.
