[0002] In the field of packaging technology, with the continuous enhancement of environmental awareness and the increasing requirements for product packaging quality, pulp containers, as a degradable and environmentally friendly packaging material, have been more and more widely used. Although traditional pulp containers have good environmental performance, they have certain limitations in terms of waterproof, moisture-proof and barrier properties, which to a large extent restricts their application in some fields with high packaging requirements. In order to improve the performance of pulp containers, laminating technology came into being. Therefore, there is a special need for a pulp container laminating device and a method of using the same.

The upper surface of the support plate 13 is fixedly connected to the limiting slide 1401, the limiting slide 1 The upper surface of 401 is slidably connected with the first displacement platform 1402, and the side surface of the first displacement platform 1402 is fixedly connected with the first displacement motor 1403. The upper surface of the first displacement platform 1402 is snap-connected with the unit mold 1404, and the side surface of the unit mold 1404 is fixedly connected with the unit spring 1405, and the side surface of the unit spring 1405 is fixedly connected with the push block 1406, and the side surface of the push block 1406 is fixedly connected with the unit latch 1407. The upper surface of the first displacement platform 1402 is snap-connected with the combined mold 1408, and the side surface of the combined mold 1408 is fixedly connected with the engaging total block 1409, and the side surface of the engaging total block 1409 is fixedly connected with the combined spring 1410, and the side surface of the combined spring 1410 is fixedly connected with the combined latch 1411. The upper surface of the limiting slide 1401 is also slidably connected with the second displacement platform 1412, and the side surface of the second displacement platform 1412 is fixedly connected with the second displacement motor 1411. The machine 1413, through the setting of the limiting slide groove 1401, the first displacement platform 1402, the first displacement motor 1403, the unit mold 1404, the unit spring 1405, the push block 1406, the unit latch 1407, the combined mold 1408, the engaging total block 1409, the combined spring 1410, the combined latch 1411, the second displacement platform 1412 and the second displacement motor 1413, when in use, for the replacement of the unit mold 1404, press the push block 1406. After the push block 1406 is subjected to pressure, it will squeeze the unit spring 1405. The unit spring 1405 contracts, driving the unit latch 1407 to disengage from the engaging position of the first displacement platform 1402. At this time, the original unit mold can be removed and replaced with a new unit mold. After the replacement is completed, release the push block 1406. Due to the elastic restoring force of the unit spring 1405, the unit latch 1407 will be pushed back to the original engaging position, so that the new unit mold will be reengaged with the first displacement stage 1402, thereby fixing the unit mold and completing the replacement of the unit mold. For the replacement of the combination mold 1408, after pressing the relevant parts, the combination spring 1410 will contract, driving the combination latch 1411 to disengage from the engaging position of the second displacement stage 1412. Then remove the old combination mold and replace it with a new one. After releasing the operating parts, the combination spring 1410 will restore its elasticity and push the combination latch 1411 back, so that the combination mold will be reengaged with the second displacement stage 1412, and the replacement of the combination mold will be completed.In this way, through the mold replacement mechanism, it is convenient to quickly replace the appropriate mold according to the specific shape and size requirements of the pulp container to achieve efficient laminating operation.

[0021] Furthermore, one set of side panels 6 is symmetrically arranged on the left and right sides above the unwinding bracket 2, and five sets of unwinding roller groups 4 are arranged between the two sets of side panels 6. Through the arrangement of the side panels 6, when in use, the two sets of symmetrically arranged side panels 6 play a good role in limiting and supporting the unwinding roller group 4. The unwinding roller group 4 is restricted between the two sets of side panels 6, which can prevent the unwinding roller from deviating in the left and right directions during the unwinding process, and this symmetrical side panel structure can ensure that the unwinding roller group 4 rotates and unwinds stably, so that the cold film can be smoothly unwound, providing a stable material supply for the subsequent laminating work.

[0022] Furthermore, a group of connecting blocks 7 and positioning strips 8 are respectively arranged on the left and right sides of the inner side of the coating bracket 3, and the positioning strips 8 are slidably connected to the cold film 5, and two groups of limiting slide grooves 1401 are arranged in parallel on the left and right surfaces of the upper surface of the support plate 13, and each group is provided with two. Through the setting of the connecting blocks 7 and the positioning strips 8, when in use, this design can ensure the position accuracy of the cold film 5 during the coating process, so that the cold film can be accurately covered on the pulp container, thereby improving the quality and accuracy of the coating and ensuring that the position and effect of the coating of each pulp container are consistent.

[0023] Furthermore, the size of the first translation platform 1402 is larger than that of the second translation platform 1412, and under normal conditions, the second translation platform 1412 is hidden under the first translation platform 1402, and a group of unit springs 1405, push blocks 1406 and unit latches 1407 are respectively arranged on the left and right sides of the unit mold 1404. Through the arrangement of the first translation platform 1402 and the second translation platform 1412, when in use, the smaller second translation platform 1412 is hidden under the larger first translation platform 1402. This design effectively reduces the space occupied by the equipment in the horizontal direction, improves the space utilization rate of the entire workshop, and reduces production costs.

[0024] Furthermore, a group of combination springs 1410 and combination tongues 1411 are respectively provided on the left and right surfaces of the combined mold 1408, and a group of combination springs 1410 and combination tongues 1411 are respectively provided on the left and right surfaces of the combined mold 1408. Through the provision of the combined block 1409 and the combination springs 1410, when in use, the combined block 1409 is provided with a group of combination springs 1410 and combination tongues 1411 on both sides of the combined mold 1408, and a group of combination springs 1410 and combination tongues 1411 are respectively provided on both sides of the combined block 1409. This bilaterally symmetrical design can make the combined mold 1408 more firmly fixed on the second displacement platform 1412. The bilateral fixing method can effectively disperse these forces and prevent the combined mold 1408 from loosening or displacement during operation, thereby ensuring the accuracy and quality of the coating.

[0025] Furthermore, the unit mold 1404 is engaged and connected with the first displacement platform 1402 through the unit spring 1405 and the unit latch 1407, and the combined mold 1408 is engaged and connected with the second displacement platform 1412 through the combined spring 1410 and the combined latch 1411. Through the arrangement of the unit spring 1405, the unit latch 1407, the combined spring 1410 and the combined latch 1411, when it is necessary to replace molds of different specifications or types to meet the requirements of different pulp container coatings, the operator only needs to press the pressing block 1406 or the parts related to the combined latch 1411 to overcome the elastic force of the unit spring 1405 or the combined spring 1410, so that the unit latch 1407 or the combined latch 1411 is disengaged from the engaged position of the displacement platform, and the mold can be easily removed. Compared with traditional bolt connections or complex mechanical fixing methods, this operation does not require the aid of additional tools, and can complete the disassembly of the mold in a short time, greatly saving the time for replacing the mold.

[0026] Furthermore, the segmentation mechanism 15 includes a segmentation bracket 1501, an inclined slot plate 1502, a pressing handle 1503, a roller 1504, a concave-convex block 1505, a reset spring 1506, a reset support block 1507 and a tic-tac-toe blade 1508. The upper surface of the displacement bracket 1 is fixedly connected to the segmentation bracket 1501, the upper surface of the segmentation bracket 1501 is rotatably connected to the inclined slot plate 1502, a side surface of the inclined slot plate 1502 is fixedly connected to the pressing handle 1503, the lower surface of the inclined slot plate 1502 is slidably connected to the roller 1504, the lower surface of the roller 1504 is fixedly connected to the concave-convex block 1505, the lower surface of the concave-convex block 1505 is fixedly connected to the reset spring 1506, and the lower surface of the reset spring 1506 is fixedly connected to the reset support block 1507. The support block 1507, the lower surface of the reset support block 1507 is fixedly connected with a tic-tac-toe blade 1508, through the arrangement of the split bracket 1501, the inclined slot plate 1502, the pressing handle 1503, the roller 1504, the concave-convex block 1505, the reset spring 1506, the reset support block 1507 and the tic-tac-toe blade 1508, when in use, the operator operates the pressing handle 1503, because the pressing handle 1503 is fixedly connected to the inclined slot plate 1502, and the inclined slot plate 1502 is rotationally connected to the split bracket 1501, so when the pressing handle 1503 is pressed, the inclined slot plate 1502 will be driven to rotate around the rotation connection with the split bracket 1501, and as the inclined slot plate 1502 rotates, its lower surface slides relative to the roller 1504. Because the roller 1504 is fixed on the upper surface of the concave-convex block 1505, the sliding of the roller 1504 on the chute plate 1502 will drive the concave-convex block 1505 to move downward. Because the concave-convex block 1505 is connected to the reset support block 1507 through the reset spring 1506, and the tic-tac-toe blade 1508 is fixedly connected below the reset support block 1507, the downward movement of the concave-convex block 1505 drives the reset support block 1507 and the tic-tac-toe blade 1508 to move downward in turn, and the tic-tac-toe blade 1508 moves downward until it contacts the coated and processed pulp container below, and performs a segmentation operation on it, segmenting it into individual finished products. The operation of pressing the handle can easily segment the coated and processed pulp container into individual finished products, which is more time-saving and labor-saving than manual cutting one by one, and also reduces the production cost of the enterprise.

[0027] Furthermore, the pressing handle 1503 is rotatably connected to the split bracket 1501 through the inclined groove plate 1502, and five groups of rollers 1504 are arranged on the upper surface of the concave-convex block 1505. Through the arrangement of the rollers 1504, when in use, the five groups of rollers 1504 are evenly distributed on the upper surface of the concave-convex block 1505. When the inclined groove plate 1502 rotates and slides with the rollers 1504, the pressure applied by the inclined groove plate 1502 can be evenly dispersed to the concave-convex block 1505, which avoids the situation of excessive local force, reduces the risk of component damage or deformation due to uneven force, and extends the service life of the concave-convex block 1505 and related components.

[0028] Further, the reset support block 1507 and the tic-tac-toe blade 1508 are slidably connected with the segmentation bracket 1501 through the reset spring 1506, and the tic-tac-toe blade 1508, the reset support block 1507, the concave-convex block 1505 and the roller 1504 are fixedly connected structures. Through the arrangement of the tic-tac-toe blade 1508, the reset support block 1507, the concave-convex block 1505 and the roller 1504, when in use, the reset support block 1507, the concave-convex block 1505 and the roller 1504 are fixedly connected with the tic-tac-toe blade 1508, so that the whole structure can move in coordination during operation. When the operator operates the pressing handle and drives the roller 1504 to slide on the tic-tac-toe plate through the chute plate, this fixed connection structure can ensure that the tic-tac-toe blade 1508 descends vertically and stably, ensuring the accuracy of the cutting action. Accurate cutting can make the size of each pulp container after segmentation meet the requirements, the edges are neat, and the product quality is improved. Example 2

After completion, the pressing block 1406 is released, and the unit spring 1405 or the combination spring 1410 resets the latch to fix the mold; Step 3: Start the winding motor 10 to drive the winding roller 9 to rotate. The cold film 5 on the unwinding roller group 4 starts to unwind under the action of friction.

The tic-tac-toe blade 1508 divides the coated and processed pulp container into individual finished products. After the division is completed, release the pressing handle 1503, and the reset spring 1506 resets the tic-tac-toe blade 1508 and other components, waiting for the next division operation.

[0030] Working principle: This pulp container coating equipment, when in use, when the pulp container coating equipment is working, first put the pulp container in place, confirm that the cold film 5 on the unwinding roller group 4 is correctly installed, the unit mold 1404 or the combined mold 1408 in the mold replacement mechanism 14 is in the initial state, and the dividing mechanism 15 is on standby. When the mold needs to be replaced, press the push block 1406 to make the unit clamping tongue 1407 disengage from the first displacement platform 1402 to complete the replacement of the unit mold 1404, or press the parts related to the combined clamping tongue 1411 to replace the combined mold 1408, and use the unit spring 1405 or the combined spring 1410 to reset the fixed mold. Then start the winding motor 10, the winding roller 9 rotates, and the cold film 5 is unwound by friction. The cold film 5 slides along the positioning card strip 8, and the cylinder 11 pushes the laminating push plate 12 to fit the cold film 5 on the pulp container to complete the laminating. Finally, the handle 1503 is pressed to rotate the inclined groove plate 1502, and the roller 1504 slides to drive the concave-convex block 1505, the reset support block 1507 and the tic-tac-toe blade 1508 downward to divide the coated pulp container into individual finished products. After completion, the handle is released, and the reset spring 1506 resets each component to wait for the next operation. The model of the winding motor 10 is Y315S-2, the model of the pushing cylinder 11 is XYDHA24-800, and the model of the first and second displacement motors is WL-37RS528.
