Description

Technical Field

[0001] This utility model relates to the field of coated paper processing technology, and more specifically, to a coated paper processing device. Background Technology

[0002] Coated paper is a composite material in which plastic particles (such as PE and PP) are coated onto the surface of paper using a casting machine. It has the characteristics of being oil-proof, waterproof (relatively), and heat-sealing. The production process of coated paper includes steps such as base paper preparation, coating, cooling, hot stamping, and slitting.

[0003] For example, a utility model patent with publication number CN221774723U discloses a device for processing hot-stamping holes in coated paper, including a base, a winding and unwinding assembly connected to the upper end of the base, and a tension adjustment assembly connected to the upper end of the base.

[0004] The above-mentioned patent has the following problems when in use: Although the structural component for hot-stamping holes in coated paper realizes the increase or decrease of the number of hot-stamping holes through threaded connection, the operation of independently controlling the hot-stamping component to screw in or out is relatively cumbersome and lacks stability; in addition, the hot-stamping process of coated paper will produce volatile organic odor, which is quite irritating and affects the working environment.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a coating paper processing device in order to achieve a more practical purpose. Utility Model Content

The positioning seat is disposed between the upper plate and the lower plate, and the positioning block is inserted into the upper surface of the lower plate.

[0010] In a preferred embodiment, the mounting structure includes a threaded post fixedly connected to the upper surface of the lower plate, with one end of the threaded post passing through the upper plate. A spring washer is fitted onto the threaded post, and a wing nut is threaded onto the threaded post.

[0011] In a preferred embodiment, a pad is fixedly connected to the top of the lower plate, and a slider two is fixedly connected to the side of the pad. The slider two is slidably connected to the inner wall of the suction pipe.

[0012] In a preferred embodiment, the rebound assembly includes a pair of fixed blocks, both of which are fixedly connected to the side of the fixing frame. A smooth rod is fixedly connected between the pair of fixed blocks. A movable block is slidably connected to the smooth rod. The movable block is fixedly connected to the outer surface of the suction pipe. A compression spring is sleeved on the smooth rod, and the compression spring is located below the movable block.

[0013] In a preferred embodiment, a damping pad is fixedly connected to the bottom of the fixed block at the top, the movable block is in movable contact with the damping pad, and a pressure pad is fixedly connected to the bottom of the suction pipe.

[0014] In a preferred embodiment, the air filtration unit includes a filter box, which is fixedly connected to the mounting frame.

[0015] In a preferred embodiment, the tray is provided with pinholes for the insertion of heat-conducting copper needles.

[0016] The technical effects and advantages of this utility model are as follows: 1. This coating paper processing device places multiple heat-conducting copper pins on the lower plate in a loading manner, and the upper and lower plates are controlled by the installation structure to achieve assembly and disassembly. In this way, the heat-conducting copper pins can be quickly connected to the heating tube. While ensuring the thermal response of the heat-conducting copper pins, the efficiency of increasing or decreasing the number of heat-conducting copper pins can be improved, and the hot hole adjustment can be facilitated.

[0017] 2. This coated paper processing device, by setting up an air extraction pipe and an air filter unit, allows the air extraction pipe to descend and drive the pressure pad to press the coated paper on the support plate when the heat-conducting copper needle performs the pressing action of the hot-hole. By positioning and pressing the coated paper of the hot-hole, the accuracy of the hot-hole can be guaranteed. At the same time, because the air extraction pipe is close to the coated paper when pressing it, the negative pressure of the air pump can introduce the volatile organic compounds generated by the hot-hole inside the air extraction pipe into the filter box. The honeycomb activated carbon plate can adsorb odor molecules using honeycomb micropores, eliminating the odor of the hot-hole and preventing the odor from affecting the health of personnel.

[0021] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] See also Figures 1-8 This utility model provides a coating paper processing device for hot-stamping processing of coating paper. The inner side of the fixing frame 1 is provided with an upper plate 2, a lower plate 3, an air extraction pipe 4 and a support plate 5 from top to bottom. The end of the fixing frame 1 is provided with a mounting hole, which can be connected to the mounting surface with bolts.

[0023] In this embodiment: a hydraulic cylinder 6 is fixedly connected to the top of the fixed frame 1. The output end of the hydraulic cylinder 6 passes through the fixed frame 1 and is fixedly connected to the upper plate 2. A slider 20 is fixedly connected to the periphery of the upper plate 2. The slider 20 is slidably connected to the inner wall of the fixed frame 1.

[0024] The extension and retraction of the piston end of the hydraulic cylinder 6 can drive the upper plate 2 to move up and down inside the fixed frame 1. The inner wall of the fixed frame 1 is provided with a sliding groove that cooperates with the sliding block 20. The sliding block 20 can make the up and down of the upper plate 2 highly stable.

[0025] In this embodiment, multiple heating tubes 7 are fixedly connected to the bottom of the upper plate 2.

[0026] The heating element 7 has a built-in heating resistance wire, which can be connected to an existing temperature controller, so that the heating temperature of the heating element 7 can be precisely controlled; since the upper plate 2 can lift the base, the heating element 7 can move with the upper plate 2.

[0027] In this embodiment: a plurality of heat-conducting copper pins 8 are provided through the lower plate 3. The heat-conducting copper pins 8 are inserted into the heating tube 7. The top of the heat-conducting copper pins 8 is fixedly connected to a positioning seat 21. The bottom of the positioning seat 21 is fixedly connected to a positioning block 22. The positioning seat 21 is located between the upper plate 2 and the lower plate 3. The positioning block 22 is inserted into the upper surface of the lower plate 3.

[0028] In this application, the heat-conducting copper needle 8 is provided with an insertion hole for the heating tube 7. The lower plate 3 is provided with a through hole for the heat-conducting copper needle 8 to pass through. By inserting the heat-conducting copper needle 8 into the through hole, the positioning seat 21 can support the position of the heat-conducting copper needle 8. The positioning seat 21 is also provided with a hole similar to the insertion hole. The lower plate 3 is provided with a slot for the positioning block 22 to be inserted. The positioning block 22 is inserted into the slot to prevent the positioning seat 21 from shifting. This can stabilize the longitudinal position of the heat-conducting copper needle 8. Subsequently, the lower plate 3 and the upper plate 2 are brought closer together, and the heating tube 7 can be inserted into the insertion hole of the heat-conducting copper needle 8. By bringing the heating tube 7 close to the heat-conducting copper needle 8, the heat of the heating tube 7 can be quickly transferred to the heat-conducting copper needle 8, ensuring the reliability of the heat-conducting copper needle 8 in the hot hole.

[0029] In this embodiment: an installation structure is provided between the upper plate 2 and the lower plate 3. The installation structure includes a threaded post 9, one end of which passes through the upper plate 2. The threaded post 9 is fixedly connected to the upper surface of the lower plate 3. A spring washer 10 is sleeved on the threaded post 9, and a wing nut 11 is threadedly connected to the threaded post 9.

[0030] When it is necessary to adjust the number of heat-conducting copper needles 8, the wing nut 11 on the threaded post 9 can be removed, and the upper plate 2 and lower plate 3 can be separated. After adjusting the number of heat-conducting copper needles 8 placed on the lower plate 3, the threaded post 9 can be passed through the upper plate 2. At this time, the heating tube 7 can be inserted into the heat-conducting copper needle 8. The spring washer 10 is placed on the threaded post 9, and the wing nut 11 is threaded to the threaded post 9 and presses the spring washer 10 on the top of the upper plate 2. In this way, the heat-conducting copper needle 8 can be locked on the heating tube 7 of the upper plate 2. The subsequent hot hole operation of the heat-conducting copper needle 8 is more stable. Moreover, since the number of heat-conducting copper needles 8 can be quickly increased or decreased by directly controlling the disassembly and assembly of the upper plate 2 and the lower plate 3, the adjustment efficiency of multi-station hot hole operation can be improved.

[0031] In this embodiment, the tray 5 is provided with a pinhole 26 for the heat-conducting copper needle 8 to be inserted.

[0032] The surface of the tray 5 can be polished and coated with a paper. When the heat-conducting copper needle 8 heats the paper on the tray 5, the end of the heat-conducting copper needle 8 can be inserted into the needle hole 26, which can improve the forming quality of the heat-conducting paper.

[0033] In this embodiment: the upper plate 2 and the suction pipe 4 are in active contact. A spring-loaded assembly is provided between the fixing frame 1 and the suction pipe 4. The spring-loaded assembly includes a pair of fixing blocks 12. Both of the fixing blocks 12 are fixedly connected to the side of the fixing frame 1. A smooth rod 13 is fixedly connected between the pair of fixing blocks 12. A movable block 14 is slidably connected to the smooth rod 13. The movable block 14 is fixedly connected to the outer surface of the suction pipe 4. A compression spring 15 is sleeved on the smooth rod 13. The compression spring 15 is located below the movable block 14. A suction hole 41 is opened on the inner wall of the suction pipe 4.

[0034] The suction pipe 4 has a rectangular structure and a cross-section with a U-shaped structure. There are multiple suction holes 41, which are connected to the cavity of the suction pipe 4.

[0035] In use, the two ends of the coated paper in this application can be intermittently transported using existing coated paper winding and unwinding equipment. The coated paper can pass above the pallet 5, and the upper plate 2 is lowered by the hydraulic cylinder 6. The heat-conducting copper needle 8 set below the upper plate 2 can move toward the coated paper. When the upper plate 2 contacts the suction pipe 4 and is pressed down, the movable block 14 can slide down on the light rod 13 and compress the compression spring 15. The suction pipe 4 can approach the coated paper on the pallet 5. During this process, the lower plate 3 can descend inside the suction pipe 4 until the heat-conducting copper needle 8 heats the surface of the coated paper. When the hydraulic cylinder 6 drives the heat-conducting copper needle 8 to move upward, the elastic recovery of the compression spring 15 can make the suction pipe 4 move away from the coated paper. By setting the suction pipe 4 on the outside of the coated paper in the heat-heated state, the position of the suction hole 41 can facilitate the subsequent suction of volatile organic gases generated by the heat-heating.

[0036] In this embodiment: the bottom of the fixed block 12 located at the top is fixedly connected to a damping pad 27, the movable block 14 is in contact with the damping pad 27, and the bottom of the suction pipe 4 is fixedly connected to a pressure pad 25.

[0037] The damping pad 27 is fixed to the bottom of the fixing block 12 and set on the outside of the light rod 13. The damping pad 27 can be used to dampen the movable block 14 lifted by the compression spring 15. The pressure pad 25 can press the coated paper on the support plate 5. When the upper plate 2 drives the heat-conducting copper needle 8 to descend, the air extraction pipe 4 can drive the pressure pad 25 to contact the coated paper on the support plate 5 in advance. The pressure pad 25 fixes the coated paper before hot-drilling, which can avoid the hot-drilling hole being too large and ensure the hot-drilling hole accuracy.

[0038] In this embodiment: a pad 23 is fixedly connected to the top of the lower plate 3, and a slider 24 is fixedly connected to the side of the pad 23. The slider 24 is slidably connected to the inner wall of the suction pipe 4.

[0039] When the connection of the installation structure is disconnected due to the addition or removal of the heat-conducting copper pins 8, the hydraulic cylinder 6 is at its maximum extension stroke. After the wing nut 11 removes the threaded post 9, the heat-conducting copper pins 8 set on the lower plate 3 abut against the pin hole 26 of the support plate 5. The pad 23 sits on the support plate 5. The pad 23 can control the support height of the lower plate 3 on the support plate 5 to prevent the heat-conducting copper pins 8 from being automatically squeezed out on the lower plate 3. The inner wall of the suction pipe 4 has a sliding groove for the sliding of the second slider 24. The sliding groove is not connected to the cavity of the suction pipe 4. When the center of the lower plate 3 moves, the lower plate 3 can move smoothly on the suction pipe 4 through the second slider 24. This can correct the trajectory of the lower plate 3. The threaded post 9 can pass through the upper plate 2 more accurately. Finally, the hydraulic cylinder 6 can be controlled to drive the upper plate 2 to rise until there is enough operating space between the upper plate 2 and the lower plate 3. In this way, the number of heat-conducting copper pins 8 can be adjusted. After locking the installation structure, the hot hole position of the heat-conducting copper pins 8 can be stabilized.

[0040] In this embodiment: an air filtration unit is provided between the air extraction pipe 4 and the fixed frame 1. The air filtration unit includes a filter box 16, which is fixedly connected to the fixed frame 1. Multiple honeycomb activated carbon plates 17 are inserted into the filter box 16. An air extraction hose 18 is fixedly connected between the filter box 16 and the air extraction pipe 4. An air extraction pump 19 is provided on the top of the filter box 16.

[0041] The suction hose 18 is connected to the lumen of the suction pipe 4, and the suction end of the suction pump 19 is connected to the lumen of the suction pipe 4. In this application, the inner wall of the filter box 16 is provided with a slot for inserting the honeycomb activated carbon plate 17. In order to meet the needs of disassembling and replacing the honeycomb activated carbon plate 17, the side of the filter box 16 can be connected to the sealing cover by screws, and a sealing gasket can be provided between the filter box 16 and the sealing cover to increase the connection sealing.

[0042] When in use, when the suction pipe 4 drives the pressure pad 25 to press the coated paper tightly, and the heat-conducting copper needle 8 performs hot-drilling on the coated paper, the suction pump 19 can be controlled to work. The negative pressure of the suction pump 19 can introduce the volatile organic gas generated by the hot-drilling of the coated paper into the filter box 16 through the suction hole 41, the suction pipe 4, and the suction hose 18 in sequence. The multi-stage honeycomb activated carbon plate 17 can use its honeycomb microporous structure to adsorb odor molecules in the gas, thus maximizing the reduction of hot-drilling odor.

[0043] The specific models and specifications of the hydraulic cylinder 6, heating resistance wire, temperature controller and air pump 19 proposed in this application need to be selected and determined according to the actual specifications of the device. The specific selection calculation method, circuit connection method and control method all adopt the existing technology in the field, and the power supply is also common knowledge in the field, so it will not be described in detail.
