Description

Technical Field

[0001] This utility model relates to the field of paper drum processing technology, and in particular to a paper drum rolling device. Background Technology

[0002] In the paper drum manufacturing process, the treatment of the drum opening is one of the key steps, which directly affects the sealing performance, appearance quality and service life of the paper drum.

[0003] The utility model patent with patent application number 202321719623.5 discloses a paper drum processing rolling device, including a base, a support plate fixedly connected to the middle of the top of the base, a top plate fixedly connected to the top of the support plate, a drive motor fixedly connected to the right side of the top of the top plate, the drive end of the drive motor passing through the outer wall of the top plate and fixedly connected to a connecting shaft, and a trapezoidal rolling device fixedly connected to the bottom end of the connecting shaft.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that when the device is used to roll the edge of the barrel, the trapezoidal rolling tool directly penetrates into the inside of the barrel to roll the edge. The edge of the barrel is not heated, which can easily lead to the adhesive or coating material not softening. Direct rolling can easily result in uneven rolling or even tearing, which can reduce the quality of the finished product and affect the efficiency of rolling.

[0005] Therefore, it is necessary to invent a paper drum rolling device to solve the above problems. Utility Model Content

[0036] like Figures 1-4 As shown, a paper drum processing device disclosed herein may include a base 1, with an L-shaped bracket 12 fixedly connected to the top of the base 1; a placement component for placing the paper drum; a drum rolling component for rolling the paper drum; a heating component for heating the edge of the drum opening; and an air cooling component for cooling and shaping the rolled drum opening.

[0037] like Figure 4 As shown, in this disclosure, the seam assembly includes a trapezoidal seam reel 8, and the bottom end of the trapezoidal seam reel 8 is provided with a fitting groove 81.

[0038] The heating assembly includes an electric heater, which is located inside the trapezoidal seam reel 8. A wire interface 82 is provided on one side of the trapezoidal seam reel 8, and the wire interface 82 is electrically connected to the electric heater.

[0039] The air-cooled assembly includes a fan 6 and a fan shroud 7. The fan 6 is fixedly connected to the top of the L-shaped bracket 12. A connecting pipe 76 is provided on one side of the fan shroud 7, which is connected to the fan 6. Multiple air jet holes 75 are evenly arranged on the inner side of the fan shroud 7.

[0040] Therefore, the electric heater can be installed inside the trapezoidal seam maker 8 using modern technology, so that the trapezoidal seam maker 8 can also be heated to complete the subsequent heating of the paper drum edge. By setting the bonding groove 81, the seam can be rolled. By setting the fan hood 7, a connecting pipe 76 is set on one side of the fan hood 7, and the fan 6 can be connected to the connecting pipe 76 through a flexible hose. The inside of the fan hood 7 is hollowed out, so that cold air can circulate inside the fan hood 7. By setting the air jet hole 75, cold air can be sprayed out from the air jet hole 75. The inside of the fan hood 7 is set as a slope, so that the air blows obliquely and can directly blow to the edge of the paper drum for rapid cooling. The electric heater is connected to an external controller, so the temperature can be directly observed and easily controlled.

[0041] like Figure 4 As shown, in a preferred embodiment, a connecting rod 72 is fixedly connected to the inner side of the wind cover 7, a limiting plate 73 is fixedly connected to the bottom end of the connecting rod 72, a threaded rod 74 is fixedly connected to the bottom end of the limiting plate 73, and the threaded rod 74 is threadedly connected to the inner side of the trapezoidal reel 8.

[0042] Therefore, the connecting rod 72 is fixedly connected to the top of the inner side of the hood 7. The setting of the limiting plate 73 can effectively limit the position of the trapezoidal curling device 8. By setting the threaded rod 74, the thread of the threaded rod 74 is set counterclockwise. The trapezoidal curling device 8 is threadedly connected to the inner side of the threaded rod 74, and is also fixed in the counterclockwise direction. This makes it easy to install and fix the trapezoidal curling device 8, and also easy to disassemble and replace. The purpose of the counterclockwise setting is to prevent the paper drum from rotating in the clockwise direction during the curling process, so that the trapezoidal curling device 8 will rotate with the paper drum.

[0043] like Figure 4 As shown in this disclosure, a through groove 77 is provided on one side of the shroud 7, and the through groove 77 is correspondingly provided with the wire interface 82.

[0044] Therefore, by setting a through groove 77, an electric wire can pass through the inside of the through groove 77, and the electric wire can be plugged into the inside of the electric wire interface 82 to supply power to the electric heater set inside the trapezoidal reel 8 for heating.

[0045] like Figure 3 and Figure 4 As shown, in a preferred embodiment, a servo cylinder 5 is fixedly connected to the top of the L-shaped bracket 12, a connecting shaft 51 is fixedly connected to the output end of the servo cylinder 5, a first mounting plate 52 is fixedly connected to the bottom end of the connecting shaft 51, a second mounting plate 71 is provided at the bottom end of the first mounting plate 52, and the second mounting plate 71 is fixedly connected to the top of the fan cover 7.

[0046] Therefore, by setting the first mounting plate 52 and the second mounting plate 71, it is easy to fix the first mounting plate 52 to the top of the second mounting plate 71 with bolts. By setting the servo cylinder 5, the servo cylinder 5 can effectively drive the first mounting plate 52 to move up and down, that is, it can effectively drive the wind cover 7 to move up and down, which facilitates the completion of the subsequent rolling work.

[0047] like Figure 1 and Figure 2 As shown in this disclosure, the placement component includes a placement groove 2. An inner groove 11 is provided at the top of the inner side of the base 1. The placement groove 2 is rotatably disposed inside the inner groove 11. A support platform 21 is fixedly connected to the bottom of the inner side of the placement groove 2. Clamping plates 4 are symmetrically arranged on both sides of the top of the support platform 21. A through hole 43 is provided inside the clamping plate 4. An adjusting bolt 3 is rotatably disposed inside the through hole 43. The adjusting bolt 3 is threadedly connected to the inner side of the placement groove 2.

[0048] Therefore, by setting up the placement slot 2, it is convenient to place the paper drum inside the placement slot 2. The support platform 21 can effectively support the paper drum. By setting up the clamping plate 4, two clamping plates 4 are symmetrically arranged and both are set at the top of the support platform 21. The adjusting bolt 3 is threaded to the inside of the placement slot 2 and is rotatably set inside the through hole 43. The rotation of the adjusting bolt 3 can effectively drive the clamping plate 4 to move, thereby facilitating the limiting clamping work of the paper drum set at the top of the support platform 21. A motor is set on the inside of the base 1. The motor is connected to the placement slot 2 for transmission, thereby effectively driving the placement slot 2 to rotate. The motor drives the placement slot 2 to rotate clockwise.

[0049] In practical use, the paper drum is placed inside the placement slot 2. The support platform 21 can effectively support the paper drum. Rotating the adjusting bolt 3 can effectively drive the clamping plate 4 to move, thereby facilitating the limiting and clamping of the paper drum set at the top of the support platform 21.

[0050] At the same time, the heater is started to drive the trapezoidal seam reel 8 to start preheating, so that the temperature of the trapezoidal seam reel 8 rises to 80℃-120℃. After the temperature is reached, the servo cylinder 5 is started to drive the trapezoidal seam reel 8 to move downward to the edge of the paper drum to soften the adhesive and coating material.

[0051] After softening is complete, the electric heater stops working, and the motor installed in the base 1 drives the placement groove 2 to rotate. At this time, the servo cylinder 5 can slowly drive the trapezoidal curling head 8 to move, so that the paper drum rotates on the outside of the bonding groove 81 to complete the curling work.

[0052] After the seam-rolling process is completed, the servo cylinder 5 drives the trapezoidal seam-roller 8 to move upward, so that the bonding groove 81 is away from the paper drum. At this time, the fan 6 is turned on so that cold air is blown out from the jet hole 75 to cool and shape the edge of the paper drum.

[0053] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
