Description

Technical Field

[0001] This invention relates to paper discs, and more specifically, to a production line for the stacking and hot pressing of coated paper discs. Background Technology

[0002] Paper plates are paper containers made from white cardboard made from chemical wood pulp and pressed by a rolling mill. They are lightweight and can be used to hold Western-style main dishes, as well as bread, cakes, and pastries. Therefore, there is a great demand for paper plates in daily life.

[0003] The key technical features of the multi-station large-scale high-speed paper disc machine announced in Chinese Patent Publication No. CN210415659U are as follows: the feeding mechanism pushes the paper to the paper suction mechanism, the paper suction mechanism absorbs the paper to the acceleration and positioning mechanism, the acceleration and positioning mechanism sends the paper between the mold cavity and the mold punch, the material blocking mechanism in the mold frame positions the paper between the mold cavity and the mold punch, the power mechanism drives the mold cavity and the mold punch to close the mold and extrude the paper into shape, and then the mold is opened. The finished paper disc falls onto the conveyor belt through the finished product guide plate, and the conveyor belt carries the finished paper disc out of the frame for packaging.

[0004] The above technical solution improves production efficiency, reduces costs, reduces material waste, and is simple and easy to operate, filling the gap in domestic semi-automated production. The product quality is stable and the service life is long. However, manual operation is still required during use, and fully automated production has not been achieved. In addition, during the finished product processing, only one sheet of paper can be processed at a time, resulting in low production efficiency.

[0005] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Summary of the Invention

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0027] like Figure 1As shown, a stacking and hot-pressing production line for coated paper discs includes an unwinding and clamping mechanism 1 and a finished product conveying mechanism 2. The unwinding and clamping mechanism 1 includes a clamping mechanism 10 for clamping raw materials and several clamping rollers 11 for conveying raw materials. A raw material base 3 is connected to the clamping mechanism 10 and the clamping rollers 11. A pre-cutting mechanism 4 is provided on the raw material base 3. A positioning mechanism 5, a lifting and limiting mechanism 6, a pushing and stacking mechanism 7, and a forming mechanism 8 are provided between the pre-cutting mechanism 4 and the finished product conveying mechanism 2. A storage rack 9 is connected to the positioning mechanism 5, the lifting and limiting mechanism 6, and the pushing and stacking mechanism 7. A storage base plate 12 is provided on the storage rack 9. The forming mechanism 8 includes an upper mold forming mechanism 80 and a lower mold forming mechanism 81. A tail material shredding mechanism 13 is provided between the forming mechanism 8 and the finished product conveying mechanism 2.

[0028] In use, the raw material is clamped by the clamping mechanism 10 of the unwinding and feeding mechanism 1, and part of the raw material is extracted so that it can enter the pre-cutting mechanism 4 via the clamping roller 11. The clamping mechanism 10 provides driving force so that the raw material can continuously enter the pre-cutting mechanism 4. The raw paper in the pre-cutting mechanism 4 is pre-cut and cut. After this process is completed, the raw material enters the storage base plate 12. The storage base plate 12 is divided into two areas, which function as positioning and stacking, respectively. Positioning mechanism 5 and lifting limit mechanism 6 are provided in both areas of the storage base plate 12. The raw material first enters the first area of ​​the storage rack 9. The lifting limit mechanism 6 of the first area is activated to limit the raw material in the horizontal direction. Then, the positioning mechanism 5 limits the raw material in the vertical direction. After the operation is completed, the material is pushed out. The stacking mechanism 7 pushes the positioned raw material into the second area of ​​the storage rack 9. The lifting limit mechanism 6 and the positioning mechanism 5 of the second area are activated to complete the positioning of the material in the horizontal and vertical directions. Through multiple pushes by the pushing and stacking mechanism 7, the number of stacked raw materials is sufficient. Then, the pushing and stacking mechanism 7 grabs the raw material onto the lower mold forming mechanism 81 of the forming mechanism 8. The upper mold forming mechanism 80 and the lower mold forming mechanism 81 cooperate to complete the forming operation. Since the material to be formed is a disc, the edge of the disc-shaped material is relatively shallow, and multiple discs can be processed at the same time, thereby improving the processing efficiency. The waste material after processing is then carried by the pushing and stacking mechanism 7 to the tail material shredding mechanism 13 to complete the shredding operation, so as to avoid the waste material affecting the subsequent processing of finished products. The finished products are transported by two groups of finished product conveying mechanisms 2 to leave the device.

[0029] like Figure 2 and Figure 3As shown, the clamping mechanism 10 includes a clamping base plate 100. One side of the clamping base plate 100 is rotatably connected to the raw material base platform 3. The raw material base platform 3 is connected to two clamping cylinders 102 respectively through two clamping seats 101. Both clamping cylinders 102 are rotatably connected to the bottom of the clamping base plate 100 through a clamping rotating plate 103. Two clamping connecting plates 104 are provided on the top of the clamping base plate 100. Each of the two clamping connecting plates 104 has a clamping groove 105. The opposite sides of the clamping base plate 100 are connected to clamping motors 107 through clamping side plates 106. Each of the two clamping motors 107 is provided with a clamping wheel 108.

[0030] The clamping mechanism 10 can lift the raw materials on the ground, saving manpower and improving the clamping efficiency. Specifically, two clamping cylinders 102 are set at an angle. Through the connection between the clamping cylinders 102 and the clamping rotating plate 103, the clamping base plate 100 is driven to rotate. When the clamping base plate 100 is lowered to a specified height, the shaft of the raw material is inserted into the clamping groove 105 of the clamping connecting plate 104 to complete the clamping. The clamping cylinders 102 drive the clamping base plate 100 to reset. The clamping motor 107 drives the shaft of the raw material to rotate, so that part of the raw material can enter the clamping roller 11 to complete the subsequent process.

[0031] like Figure 2 and Figure 3 As shown, the pre-cutting mechanism 4 is provided on the upper pre-cutting base plate 40 and the lower pre-cutting base plate 41 on the raw material base platform 3. A connecting plate 42 is provided on one side of the lower pre-cutting base plate 41. The top of the connecting plate 42 is connected to the pre-cutting roller 43 through the connecting seat. A cutting machine 44 is provided on the side of the raw material base platform 3 facing the positioning mechanism 5.

[0032] The raw material enters the pre-cutting mechanism 4 via the connecting plate 42. The pre-cutting roller 43 allows the raw material to smoothly enter between the upper pre-cutting base plate 40 and the lower pre-cutting base plate 41 without causing the raw material to shift and affect subsequent processing. After the upper pre-cutting base plate 40 and the lower pre-cutting base plate 41 work together to complete the pre-cutting of the raw material, the raw material enters the lower part of the cutting machine 44. The cutting machine 44 cuts the raw material into segments to meet the subsequent processing requirements.

[0033] like Figure 5 and Figure 6 As shown, there are four sets of positioning mechanisms 5. The four sets of positioning mechanisms 5 are respectively set on both sides of the storage base plate 12. The positioning mechanism 5 includes a positioning plate 50. Several positioning guide rods 51 are set on the positioning plate 50. The positioning guide rods 51 are connected to the storage rack 9 through the positioning base 52. Positioning cylinders 53 are set on the positioning base 52 of the three sets of positioning mechanisms 5. Positioning connecting plates 54 are set on the piston rod of the positioning cylinder 53. One side of the positioning connecting plate 54 is bolted to the positioning plate 50. The positioning plate 50 is connected to the positioning guide rods 51.

[0034] As mentioned above, the storage base plate 12 is divided into two areas. The cut raw materials first enter the first area. In the first area, one set of positioning mechanisms 5 is equipped with a positioning cylinder 53, while the other set is not equipped with a positioning cylinder 53. The positioning mechanism 5 of the set equipped with the positioning cylinder 53 is used to control the displacement of the positioning plate 50 in the horizontal direction. Specifically, the positioning cylinder 53 is the power source. The piston rod of the positioning cylinder 53 pushes the positioning plate 50 to move through the positioning connecting plate 54, so that the raw materials in the first area are accurately positioned in the vertical direction.

[0035] This section further explains the positioning principle in the second area of ​​the storage base plate 12. The two sets of positioning mechanisms 5 in the second area are each equipped with a positioning cylinder 53. Since the raw materials in the second area need to be stacked, the two sets of positioning mechanisms 5 control the displacement of the positioning plate 50 in the vertical direction. Specifically, after the raw materials are transported to the second area, the positioning cylinder 53 is activated. The positioning cylinder 53 drives the positioning plate 50 to move through the positioning connecting plate 54, so that the raw materials in the second area are accurately positioned in the longitudinal direction.

[0036] like Figure 5 and Figure 6 As shown, there are two sets of lifting and limiting mechanisms 6. Both sets of lifting and limiting mechanisms 6 are set on the storage rack 9. The lifting and limiting mechanism 6 includes a limiting cylinder 60. The limiting cylinder 60 is connected to several limiting rods 62 through a limiting connecting plate 61 or through its piston rod. Several limiting grooves 63 are provided on the storage base plate 12 for the limiting rods 62 to move.

[0037] Two sets of lifting and limiting mechanisms 6 are located in two areas of the storage base plate 12. Two limiting cylinders 60 are set in the first area. The two limiting cylinders 60 are set at both ends of the storage base plate 12 to position the raw material in the longitudinal direction. One limiting cylinder 60 is set in the second area. The limiting cylinder 60 raises and lowers multiple limiting rods 62 through the limiting connecting plate 61 to complete the longitudinal positioning of the raw material.

[0038] like Figure 5 and Figure 6 As shown, the material pushing and stacking mechanism 7 includes a material pushing mechanism 70 and a stacking mechanism 71. The material pushing mechanism 70 has several sets. The material pushing mechanism 70 includes a material pushing cylinder 700. The bottom of each material pushing cylinder 700 is provided with a material pushing connecting plate 701. The material pushing connecting plate 701 is connected to a material pushing slide plate 702. The material pushing slide plate 702 is slidably connected to the bottom of the storage rack 9. Each piston rod of the material pushing cylinder 700 is provided with a material pushing plate 703. The material pushing plate 703 passes through the storage base plate 12. The storage base plate 12 is provided with a material pushing groove 704 for the material pushing plate 703 to slide. The stacking mechanism 71 consists of two sets, which are respectively set on one side of the storage base plate 12. The pushing stacking mechanism 71 includes several stacking cylinders 710. Each stacking cylinder 710 is equipped with a stacking connecting plate 711. Each stacking connecting plate 711 is equipped with a gripper cylinder 712. Each gripper cylinder 712 is equipped with a stacking gripper 713. A stacking mounting plate 714 is set on one side of the stacking cylinder 710. The stacking mounting plate 714 is slidably connected to a stacking bottom rail 715. The stacking bottom rail 715 is connected to the storage rack 9.

[0039] The raw materials positioned on the first area of ​​the storage base plate 12 are pushed to the second area by several sets of pushing mechanisms 70. Specifically, the pushing cylinder 700 is started, the pushing plate 703 rises, and the pushing slide plate 702 slides in the storage rack 9 through the sliding connection between the pushing slide plate 702 and the storage rack 9. The driving source of the pushing slide plate 702 is a conventional motor drive mechanism, which drives the pushing connecting plate 701 to move. If it moves back a step, the pushing cylinder 700 moves, and the pushing plate 703 on the pushing cylinder 700 slides in the pushing groove 704, so that the material is pushed to the second area of ​​the storage base plate 12. The material is pushed multiple times, and the stacking of raw materials is completed through cooperation with the lifting and limiting mechanism 6. The stacking mechanism 71 grips the stacked raw materials into the forming mechanism 8. Specifically, when the stacking cylinder 710 reaches above the raw material to be moved, the stacking connecting plate 711 drives the gripper cylinder 712 to rise and fall. The gripper cylinder 712 drives the stacking gripper 713 to clamp the raw material. After clamping, the stacking mounting plate 714 drives the stacking cylinder 710 to slide between the storage base plate 12 and the forming mechanism 8 through the sliding connection between the stacking bottom rail 715 and the stacking mounting plate 714. The drive source of the stacking mounting plate 714 is a conventional motor drive mechanism, so it will not be described in detail. The gripper cylinder 712 moves into the forming mechanism 8, the stacking gripper 713 releases, and the raw material is placed into the forming mechanism 8. After completion, the stacking cylinder 710 and other components are reset.

[0040] like Figure 7 As shown, the upper mold forming mechanism 80 includes several upper mold forming molds 801. The top of the upper mold forming mold 801 is provided with an upper fixed seat 802. Several forming guide rods 803 are slidably connected to the upper fixed seat 802. The top of the forming guide rods 803 is provided with an upper mounting plate 804, and its bottom is connected to the lower mold forming mechanism 81. A forming cylinder 805 is provided on the upper mounting plate 804. The piston rod of the forming cylinder 805 passes through the upper mounting plate 804 and is connected to the upper fixed seat 802. The lower mold forming mechanism 81 includes a plurality of lower forming molds 810. The bottom of the lower forming mold 810 is provided with a lower fixing seat 811, which is connected to the forming guide rod 803.

[0041] The lower fixed seat 811 and the forming guide rod 803 provide support for the upper mounting plate 804 and the upper fixed seat 802. After the raw material is transported between the upper mold forming mechanism 80 and the lower mold forming mechanism 81, the forming cylinder 805 drives the upper mounting plate 804 to slide on the forming guide rod 803, causing the upper forming mold 801 to descend. The upper forming mold 801 and the lower forming mold 810 perform forming processing on the raw material.

[0042] like Figure 7 and Figure 8 As shown, the tailings shredding mechanism 13 includes two tailings guide plates 130, forming a tailings guide space between the two tailings guide plates 130. Shredding blade holders 131 are bolted to the two tailings guide plates 130. The shredding blade holders 131 are bolted to one side of the lower fixed seat 811. Several shredding cylinders 132 are provided on the shredding blade holders 131. The piston rods of the shredding cylinders 132 pass through the shredding blade holders 131 and are connected to a shredding connecting plate 133. Shredding die 134 is provided on the shredding connecting plate 133. To increase the efficiency and probability of waste shredding, a secondary shredding blade can be added on the opposite side of the shredding die 134. The secondary shredding blade is set on the shredding blade holders 131.

[0043] The raw materials processed by the forming mechanism 8 will generate waste. The waste is cut off by the waste shredding mechanism. Specifically, the waste is placed between two tail guide plates 130 by the stacking jaws 713 of the stacking mechanism 71. The waste slides down along the arc of the tail guide plates 130. At this time, the shredding cylinder 132 drives the shredding knife holder 131 to move, so that the shredding die 134 can cut the waste. To facilitate subsequent collection, a collection box can also be set at the bottom of the shredding knife holder 131.

[0044] like Figure 4 As shown, the finished product conveying mechanism 2 includes a first conveyor belt 20 and a second conveyor belt 21. Both the first conveyor belt 20 and the second conveyor belt 21 are provided with a conveying platform 22. A conveying gripper 23 is provided above the first conveyor belt 20. A conveying cylinder 24 is provided on the conveying gripper 23. A conveying sliding plate 25 is provided on the conveying cylinder 24. The conveying sliding plate 25 is slidably connected to the stacking bottom rail 715. One side of the stacking bottom rail 715 is connected to the conveying platform 22 of the first conveyor belt 20.

[0045] The first conveyor belt 20 and the second conveyor belt 21 are respectively arranged horizontally and vertically, so that the finished product can leave the device and easily enter the next process. The driving mechanism of the first conveyor belt 20, the second conveyor belt 21 and the conveying sliding plate 25 is a conventional motor drive mechanism, so it will not be described in detail. The conveying sliding plate 25 moves the conveying gripper 23 above the lower forming mold 810. The conveying cylinder 24 drives the conveying gripper 23 so that the conveying gripper 23 can clamp the finished product on the lower forming mold 810. After the clamping operation is completed, the conveying sliding plate 25 resets and returns to above the first conveyor belt 20. At this time, the conveying gripper 23 releases the finished product, causing the finished product to fall onto the first conveyor belt 20, and then be transported to the second conveyor belt 21 by the first conveyor belt 20. The second conveyor belt 21 transports the finished product to the next process.

[0046] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention.
