Description

Technical Field

[0001] The present invention belongs to the field of winding equipment, and in particular, relates to a base paper coating and winding device and a base paper coating and winding method for producing paper cups. Background Art

[0002] A paper cup is a paper container made by mechanically processing and gluing base paper made of chemical wood pulp, and it has a cup-shaped appearance. In the prior art, in order to improve the leak-proof performance of paper cups, a layer of film is coated on the base paper. In addition to preventing the paper cup from leaking, the film can also play a role in forming during the production of paper cups. The base paper needs to be rolled up after laminating, but the existing winding device needs to stop winding after completing a round of rolled-up base paper. The rolled-up base paper must be disassembled and removed, and a new winding sleeve must be installed before the winding operation can be performed again. This is not only time-consuming and labor-intensive, but also has low roll-changing efficiency.

[0020] When the paper roll reaches the maximum winding diameter, the rotating bracket drives the winding shaft to rotate in a circular motion, so that another winding shaft equipped with a winding sleeve moves to the winding station, and the winding shaft with the paper roll moves to the outside of the frame, and then the base paper is cut and the cut end is wound on the surface of the new winding sleeve to continue to wind the base paper;

[0022] Then, the positioning blocks in the plurality of supporting positioning assemblies are driven to move and retract radially inward along the winding shaft by extending the driving assembly, so that the positioning blocks are separated from the inner wall of the winding sleeve and no longer support and fix the winding sleeve on the surface of the winding shaft. Then, the winding sleeve and the paper roll can be pushed toward the suspended end of the winding shaft, so that the winding sleeve and the paper roll are separated from the winding shaft, and the unloading of the winding sleeve and the paper roll is completed;

[0023] Finally, install a new winding sleeve on the winding shaft to facilitate the next round of winding work.

[0024] The present invention has the following beneficial effects:

[0025] 1. In the present invention, a plurality of winding shafts are installed by a rotating bracket. When the coated base paper is rolled up on one of the winding shafts, the rotating bracket can drive the winding shaft to rotate and make a circular motion, so that another winding shaft installed with a winding sleeve moves to the winding station, and the winding shaft with the paper roll moves to the outside of the frame. After that, the coated base paper is cut and the cut end is wound on the surface of a new winding sleeve to continue to roll up the coated base paper, so that the laminating equipment does not need to be stopped synchronously for waiting when changing the roll, which is beneficial to improving the base paper laminating efficiency.

[0026] 2. In the present invention, the two ends of the take-up shaft are respectively supported by the chuck and the rotating bracket for rolling, which can improve the stability of the take-up shaft during rotation, and thus improve the winding accuracy; and when the base paper is wound on the take-up sleeve and needs to be unloaded, the two chucks at the end of the take-up shaft are driven by the clamping drive component to move in the opposite direction and open, so that the chucks relax the clamping support on the take-up shaft, so that one end of the take-up shaft is suspended in the air, and then the telescopic drive component drives the opened chuck to move in the direction away from the take-up shaft, so that the chuck and the paper roll are staggered, and then the take-up sleeve and the paper roll can be pushed toward the suspended end of the take-up shaft, so that the take-up sleeve and the paper roll are separated from the take-up shaft, and the unloading of the take-up sleeve and the paper roll is completed. There is no need to disassemble the take-up shaft as a whole for unloading, which can make the unloading process of the take-up sleeve and the paper roll more convenient and quick.

[0027] 3. In the present invention, the positioning blocks in multiple supporting and positioning assemblies can be driven to move radially outward along the winding shaft and expand by extending the driving assembly, so that the positioning blocks are supported on the inner wall of the winding sleeve, and the winding sleeve is supported and fixed on the surface of the winding shaft, thereby facilitating the winding shaft to drive the winding sleeve to rotate and rewind. When unloading, the positioning blocks in multiple supporting and positioning assemblies are driven to move radially inward along the winding shaft and contract by extending the driving assembly, so that the positioning blocks are separated from the inner wall of the winding sleeve and no longer support and fix the winding sleeve on the surface of the winding shaft. After that, the winding sleeve and the paper roll can be pushed to the suspended end of the winding shaft for unloading. Through the cooperation of the winding sleeve, the telescopic support mechanism and the support positioning mechanism, the convenience of winding and unloading the base paper is further improved.

[0028] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In the description of the present invention, it is necessary to understand that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the invention.

[0044] Example 1: Please refer to Figure 1-Figure 3 As shown, the present invention is a base paper coating and winding device, comprising a winding mechanism 1, the winding mechanism 1 comprising a frame 11, both ends of the top of the frame 11 are rotatably mounted with rotating brackets 12, a plurality of winding shafts 13 are rotatably mounted between the two rotating brackets 12, a plurality of winding motors 14 which are transmission-connected to the winding shafts 13 in a one-to-one correspondence are fixedly mounted on one of the rotating brackets 12, a plurality of telescopic support mechanisms 2 which are rotatably connected to the winding shafts 13 in a one-to-one correspondence are fixedly mounted on the other rotating bracket 12; the telescopic support mechanism 2 comprises two clamps 211, a telescopic drive assembly and a clamping drive assembly, the two clamps 211 are closed and clamped on one end of the winding shaft 13, The end of the winding shaft 13 is supported for rotation. The clamping drive assembly can drive the two clamps 211 to move in opposite directions and open. The telescopic drive assembly can drive the opened clamps 211 to move in a direction away from the winding shaft 13. A support positioning mechanism 3 is installed on the winding shaft 13. The support positioning mechanism 3 includes an extension drive assembly and a plurality of support positioning assemblies. The plurality of support positioning assemblies are sequentially arranged along the axial direction of the winding shaft 13. Each support positioning assembly is provided with a plurality of positioning blocks 31 distributed along the circumferential direction of the winding shaft 13. The extension drive assembly can drive the positioning blocks 31 in the plurality of support positioning assemblies to move radially outward along the winding shaft 13 to expand or inward to retract.

[0045] The inner ends of the two clamps 211 are both provided with arc grooves. When the two clamps 211 are closed, they can form a circular hole structure around one end of the winding shaft 13 for rolling support. When the base paper laminating winding device is working, the winding sleeve 200 is firstly mounted on the surface of the winding shaft 13, and the positioning blocks 31 in the multiple supporting positioning components are driven by the extension driving component to move outward along the radial direction of the winding shaft 13 to expand, so that the positioning blocks 31 are supported on the inner wall of the winding sleeve 200, and the winding sleeve 200 is supported on the surface of the winding shaft 13. The support is fixed, and then the winding motor 14 drives the winding shaft 13 to rotate, and the winding shaft 13 drives the winding sleeve 200 to rotate, so that the coated base paper is wound by the winding sleeve 200 to gradually form a paper roll 100 on the surface of the winding sleeve 200; when the paper roll 100 reaches the maximum winding diameter, the rotating bracket 12 drives the winding shaft 13 to rotate and make a circular motion, so that another winding shaft 13 equipped with the winding sleeve 200 moves to the winding station, and the winding shaft 13 with the paper roll 100 moves to the outside of the frame 11, and then The base paper is cut and the cut end is wound on the surface of the new winding sleeve 200 to continue winding the base paper; then the two clamps 211 at the end of the winding shaft 13 wound with the paper roll 100 are driven by the clamping drive component to move in the opposite direction and open, so that the clamps 211 relax the clamping support on the winding shaft 13, so that one end of the winding shaft 13 is suspended in the air, and then the opened clamps 211 are driven by the telescopic drive component to move away from the winding shaft 13, so that the clamps 211 and the paper roll 100 are staggered; then the extension drive component is driven The positioning blocks 31 in the multiple supporting and positioning assemblies move inward and contract along the radial direction of the winding shaft 13, so that the positioning blocks 31 are separated from the inner wall of the winding sleeve 200 and no longer support and fix the winding sleeve 200 on the surface of the winding shaft 13. After that, the winding sleeve 200 and the paper roll 100 can be pushed toward the suspended end of the winding shaft 13, so that the winding sleeve 200 and the paper roll 100 are separated from the winding shaft 13, completing the unloading of the winding sleeve 200 and the paper roll 100; finally, a new winding sleeve 200 is installed on the winding shaft 13 to facilitate the next round of winding work.

[0046] The paper roll 100 is moved to the outside of the frame 11, and then the coated base paper is cut and the cut end is wound on the surface of the new winding sleeve 200 to continue to be wound. Therefore, it is not necessary to stop the laminating equipment synchronously and wait when changing the roll, which is beneficial to improving the base paper laminating efficiency. The two ends of the winding shaft 13 are respectively supported by the clamping head 211 and the rotating bracket 12, which can improve the stability of the winding shaft 13 during rotation, thereby improving the winding accuracy. At the same time, through the cooperation of the winding sleeve 200, the telescopic support mechanism 2 and the support positioning mechanism 3, the rolled base paper can be directly pushed and unloaded from the winding shaft 13 without the need to disassemble and remove the winding shaft 13 as a whole, thereby improving the convenience of base paper unloading.

[0047] Furthermore, a self-locking motor which is transmission-connected to one of the rotating brackets 12 is fixedly installed at the top of the frame 11, and a plurality of tensioning rollers 15 are rotatably installed on the rotating bracket 12, and the plurality of tensioning rollers 15 and the plurality of winding shafts 13 are staggered in sequence; when changing the roll, the rotating bracket 12 is driven to rotate by the self-locking motor, so that the rotating bracket 12 drives the winding shaft 13 and the tensioning roller 15 to perform circular motion synchronously, and when one of the winding shafts 13 reaches the winding station, the tensioning roller 15 between the two winding shafts 13 can limit the tension of the base paper to facilitate the subsequent cutting and rewinding of the base paper.

[0048] Example 2: Please refer to Figure 1-Figure 6 As shown, the difference between this embodiment and the above-mentioned embodiment is that the telescopic drive assembly includes a slide rail 22, the inner end of the slide rail 22 is fixedly installed with a hydraulic telescopic shaft 21, the outer end of the slide rail 22 is slidably installed with a slide seat 23, one side of the slide seat 23 is provided with a slide groove 25, the inner part of the slide groove 25 is slidably installed with a slider 26, the telescopic end of the hydraulic telescopic shaft 21 is slidably inserted and extended to the inner part of the slide groove 25, and is fixedly connected with one end of the slider 26; the clamping drive assembly includes a plurality of inclined guide grooves 28, and the plurality of inclined guide grooves 28 are symmetrically arranged in groups of two on one side of the slider 26, the inner part of the inclined guide groove 28 is slidably carded with a guide column 27, one end of the guide column 27 is fixedly installed with a telescopic slide rod 29, one end of the telescopic slide rod 29 slides through and extends to the outside of the slide groove 25, and the outer end of the telescopic slide rod 29 is fixedly installed with a connecting rod 210, one end of the connecting rod 210 is fixedly connected with a clamp 211;

[0049] A sliding hole 215 is provided on the side wall of the slider 26, a slide plate 216 is slidably installed inside the sliding hole 215, a pressure spring 214 is installed against the inner end of the slide plate 216, a limit pin 212 is fixedly installed on the outer end of the slide plate 216, a guide ball head is provided at the end of the limit pin 212, a pin hole 217 that can be engaged with the end of the limit pin 212 is provided on the side wall of the slide groove 25; a limit guide groove 24 is provided on the side wall of the slide rail 22, and the side of the slide seat 23 is fixedly installed. A limit block 218 is fixedly installed and slidably engaged in the limit guide groove 24; a second sliding hole 219 is opened on the side of the limit block 218, and a second slide plate 221 is slidably installed inside the second slide hole 219, and a second pressure spring 220 is installed against the inner end of the second slide plate 221, and a second limit pin 213 is fixedly installed on the outer end of the second slide plate 221, and a guide ball head is set at the end of the second limit pin 213, and a second pin hole 222 that can be engaged with the end of the second limit pin 213 is opened on the side wall of the limit guide groove 24;

[0050] Among them, when the two clamps 211 are in the extended clamping state, the limit pin 1 212 is staggered with the pin hole 1 217, and at this time, the limit pin 1 212 is abutted by the side wall of the slide groove 25 and retracted into the slide hole 1 215, and the limit pin 213 is clamped in the pin hole 222 to position the slide seat 23 through the pin connection. Therefore, when the hydraulic telescopic shaft 21 contracts, the hydraulic telescopic shaft 21 first drives the slider 26 to move left along the slide groove 25. At this time, the slider 26 drives the guide column 27 and the telescopic slide rod 29 to move to both sides of the slider 26 by tilting outward with the inclined guide groove 28, and then drives the two clamps 211 to move in the opposite direction and open through the connecting rods 210 on both sides, so that the clamps 211 are separated from the end of the winding shaft 13, and then the slider 26 moves to the end of the slide groove 25, and the limit pin 1 212 moves to the positive With respect to the position of the pin hole 1 217, at this time, the slide plate 1 216 and the limit pin 1 212 slide outwardly under the elastic force of the pressure spring 1 214, so that the limit pin 1 212 is inserted into the pin hole 1 217, and then as the hydraulic telescopic shaft 21 continues to drive the slide block 26 to move inward, the slide block 26 abuts against the end wall of the slide groove 25 to drive the slide seat 23 to move inward synchronously, and at the same time, the limit pin 213 contracts inwardly under the guidance of the limit ball head and gradually withdraws from the pin hole 222 to release the lock between the limit pin 213 and the pin hole 222, and when the slide seat 23 slides inwardly, the clamp 211 and the winding shaft 13 are gradually rotated and staggered, so that a sufficiently large free space is left at the suspended end of the winding shaft 13, and then the winding sleeve 200 and the paper roll 100 can be pushed and unloaded from the suspended end of the winding shaft 13;

[0051] When the unloading is completed and a new winding sleeve 200 is installed on the winding shaft 13, the slider 26 is pushed to move and reset by extending the hydraulic telescopic shaft 21. At this time, since the slider 26 and the slide seat 23 are locked by the limit pin 1 212 and the pin hole 1 217, the slider 26 moves and drives the slide seat 23 and the clamp 211 to move and reset synchronously, so that the two clamps 211 move to both sides of the end of the winding shaft 13 again, and at the same time, the limit block 218 moves to the end of the limit guide groove 24, so that the slide seat 23 is abutted against the limit and no longer moves, and at this time, the limit pin 213 is pinned to the pin hole 2 again. 222, and then as the hydraulic telescopic shaft 21 continues to extend, the hydraulic telescopic shaft 21 pushes the slider 26 to move outward along the slide groove 25 to reset. At this time, the limit pin 212 is abutted and retracted under the guiding action of the end guide ball head, and gradually withdraws from the pin hole 217 to release the lock between the limit pin 212 and the pin hole 217. Then, as the slider 26 continues to move outward, the slide plate 216 drives the guide column 27 and the telescopic slide rod 29 to move inward through the inclined guide groove 28, thereby driving the clamps 211 on both sides to move toward each other and close together, and clamping and supporting the winding shaft 13 again.

[0052] Example 3: Please refer to Figure 1 , Figure 7-10 As shown, the difference between this embodiment and the above embodiment is that the extension drive assembly includes a core shaft 32 and a plurality of limiting holes 35, the plurality of limiting holes 35 are circumferentially distributed and arranged at one end of the winding shaft 13, the core shaft 32 is slidably inserted into the interior of the winding shaft 13, and a telescopic stop block 33 is slidably engaged inside the limiting hole 35, and a transmission connecting rod 36 is rotatably installed on the inner side end of the telescopic stop block 33, and one end of the transmission connecting rod 36 is rotatably connected to the end of the core shaft 32; the support positioning assembly also includes a positioning sleeve 37 and a plurality of through grooves 39, and the plurality of through grooves 39 are circumferentially distributed and arranged on the outer wall of the winding shaft 13, and a positioning block 31 is slidably installed in each through groove 39;

[0053] The positioning sleeve 37 is fixedly mounted on the surface of the core shaft 32, and a plurality of supporting connecting rods 38 are rotatably mounted on the outer ring of the positioning sleeve 37, and one end of the supporting connecting rods 38 is rotatably connected to the inner side surface of the corresponding positioning block 31; an end plate 34 is fixedly mounted on the inner end of the core shaft 32, and the end plate 34 is slidably mounted inside the winding shaft 13, and a return spring 310 is mounted against the inner end of the end plate 34;

[0054] The telescopic stop block 33 initially extends to the outside of the limiting hole 35. When the clamp 211 is clamped and supported on the end of the winding shaft 13, the clamp 211 causes the telescopic stop block 33 to slide toward the inside of the limiting hole 35. At the same time, the telescopic stop block 33 pushes the core shaft 32 to the left through the transmission connecting rod 36. When the core shaft 32 moves to the left, it drives multiple positioning sleeves 37 thereon to move to the left synchronously. At this time, the positioning sleeve 37 drives the supporting connecting rod 38 to gradually rotate and adjust from an inclined state to a vertical supporting state. At the same time, the supporting connecting rod 38 slides the positioning block 31 to the outside of the through groove 39, thereby causing multiple positioning blocks 31 distributed in a circle to move outward and expand. At the same time, it is supported on the inner wall of the winding sleeve 200 to support and fix the winding sleeve 200 on the surface of the winding shaft 13; and when the clamp 211 moves in the opposite direction to open and move away from the end of the winding shaft 13, the clamp 211 no longer abuts against the telescopic stop block 33. At this time, the end plate 34 and the core shaft 32 move to the right and reset under the action of the reset elastic force of the reset spring 310. At the same time, the core shaft 32 pulls the positioning block 31 inward and contracts through the support connecting rod 38, so that the positioning block 31 is separated from the inner wall of the winding sleeve 200 to release the support and positioning of the winding sleeve 200, and the core shaft 32 also pushes the telescopic stop block 33 outward and resets it through the transmission connecting rod 36.

[0055] Furthermore, a ball is rotatably installed on the outer end of the telescopic abutment 33, so that when the chuck 211 is clamped and supported on the end of the winding shaft 13, the winding shaft 13 is abutted and connected with the chuck 211 through the ball, so that the multiple telescopic abutments 33 distributed in a circle can act as bearings, facilitating the rotational connection between the winding shaft 13 and the chuck 211.

[0056] Embodiment 4: This embodiment discloses a method for coating and rolling base paper for paper cup production, and the specific steps are as follows:

[0057] First, the winding sleeve 200 is mounted on the surface of the winding shaft 13, and the positioning blocks 31 in the supporting positioning components are driven by the extension driving component to move outward along the radial direction of the winding shaft 13, so that the positioning blocks 31 are supported on the inner wall of the winding sleeve 200, and the winding sleeve 200 is supported and fixed on the surface of the winding shaft 13. Then, the winding motor 14 drives the winding shaft 13 to rotate, and the winding shaft 13 drives the winding sleeve 200 to rotate, so that the coated base paper is rolled up by the winding sleeve 200, so that the paper roll 100 is gradually formed on the surface of the winding sleeve 200.

[0058] When the paper roll 100 reaches the maximum winding diameter, the rotating bracket 12 drives the winding shaft 13 to rotate and make a circular motion, so that another winding shaft 13 equipped with a winding sleeve 200 moves to the winding station, and the winding shaft 13 with the paper roll 100 moves to the outside of the frame 11, and then the base paper is cut and the cut end is wound on the surface of the new winding sleeve 200 to continue to wind the base paper;

[0059] Then, the two clamps 211 at the ends of the reel 13 wound with the paper roll 100 are driven by the clamping drive assembly to move in opposite directions and open, so that the clamps 211 loosen their clamping support on the reel 13, so that one end of the reel 13 is suspended in the air, and then the opened clamps 211 are driven by the telescopic drive assembly to move away from the reel 13, so that the clamps 211 are staggered from the paper roll 100;

[0060] Then, the positioning blocks 31 in the plurality of supporting positioning components are driven to move and retract radially inward along the winding shaft 13 by extending the driving component, so that the positioning blocks 31 are separated from the inner wall of the winding sleeve 200 and no longer support and fix the winding sleeve 200 on the surface of the winding shaft 13. Then, the winding sleeve 200 and the paper roll 100 can be pushed toward the suspended end of the winding shaft 13, so that the winding sleeve 200 and the paper roll 100 are separated from the winding shaft 13, and the unloading of the winding sleeve 200 and the paper roll 100 is completed.

[0061] Finally, a new winding sleeve 200 is installed on the winding shaft 13 to facilitate the next round of winding work.
