Description

Technical Field

[0001] This utility model relates to the field of winding technology, and in particular to a winding roller device. Background Technology

[0002] Taking label production as an example, many rollers are used on the label production line. For instance, after label printing and die-cutting, the waste material generated needs to be wound onto the waste roller; the finished labels are also wound onto the finished label roller. To prevent the rolls used for winding waste material or finished labels from moving randomly on the rollers, existing rollers have an expansion clamping function to fix the rolls. The problem is that existing rollers are not suitable for rolls of different widths; when changing rolls, workers cannot quickly move the roll to a specific position on the roller and then fix it. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a take-up roller device suitable for rolls of different widths, and for fixing the rolls.

[0004] In order to achieve the purpose of this utility model, the following solution is proposed:

[0005] A take-up roller device includes a motor, a roller, multiple clamping components, and an adjustment control.

[0006] The outer wall of the roller is used to fit the drum. The first end of the roller is rotatably mounted on the support plate. The motor is used to drive the roller. The inside of the roller is hollow. The second end of the roller is open.

[0007] Multiple clamping components are arranged in an array inside the roller along the axial direction of the roller. Each clamping component includes a column and two symmetrically arranged clamping plates. A through hole is provided at a corresponding position on the side wall of the roller, and the clamping plate is located in the corresponding through hole. Both ends of the column are fixedly connected to the inner wall of the roller. One end of the clamping plate facing the support plate is slidably engaged with the column through a convex plate. A spring is provided on the outer periphery of the column, and two convex plates are connected to both ends of the spring. The other end of the clamping plate is provided with a first inclined surface.

[0008] The control unit includes a screw, a sealing plate, multiple inserts, and two straight plates. The sealing plate is fixedly located at the second end of the roller. The screw thread passes through the sealing plate and is rotatably connected to one of the inserts. The two straight plates are symmetrically located on both sides of the clamping component. The multiple inserts are connected to the two straight plates. The inserts are located between the corresponding two clamping plates. The inserts are in close contact with the first inclined surface of the clamping plate through the second inclined surface. When the inserts move, they are used to open the two clamping plates to fix the drum.

[0009] The beneficial effects of this utility model are as follows: multiple clamping parts are provided on the roller to accommodate rolls of different widths and to fix rolls of different widths; the method of fixing the roll is very simple, just put the roll on the outer wall of the roller, and then rotate the screw, the insert will open the two clamping plates, and the inner wall of the roll can be fixed.

[0015] like Figure 1 , Figure 2 As shown, this embodiment provides a take-up roller device, including a motor 1, a roller 2, four clamping parts 3, and an adjustment control 4.

[0016] Specifically, the outer wall of roller 2 is used to fit the drum, the first end of roller 2 is rotatably mounted on support plate 11, motor 1 is used to drive roller 2, the inside of roller 2 is hollow, and the second end of roller 2 is open.

[0017] Specifically, such as Figures 1-3 As shown, four clamping members 3 are arranged in an array along the axis of the roller 2 inside the roller 2. Each clamping member 3 includes a column 32, a spring 33 and two symmetrically arranged clamping plates 31. The side wall of the roller 2 is provided with a through hole 21 at the position corresponding to the clamping plate 31. The clamping plate 31 is located in the corresponding through hole 21. The two ends of the column 32 are fixedly connected to the inner wall of the roller 2. The end of the clamping plate 31 facing the support plate 11 is slidably engaged with the column 32 through a convex plate 311. The spring 33 is located on the outer periphery of the column 32, and the two ends of the spring 33 are connected to the two convex plates 311. The end of the clamping plate 31 away from the support plate 11 is provided with a first inclined surface.

[0018] Specifically, such as Figures 1-3 As shown, the adjustment control 4 includes a screw 41, a sealing plate 42, four insert blocks 43, and two straight plates 44. The sealing plate 42 is fixedly mounted on the second end of the roller 2. The screw 41 is threaded through the sealing plate 42 and rotatably connected to the nearest insert block 43. A knob 411 is provided at the outer end of the screw 41 to rotate the screw 41. The two straight plates 44 are symmetrically arranged on both sides of the clamping member 3. Each of the four insert blocks 43 is connected to one straight plate 44. One insert block 43 corresponds to one clamping member 3, and the insert block 43 is located between the corresponding two clamping plates 31. Figure 3From the viewing angle, the two right angles on the right side of the insert 43 are provided with second inclined surfaces. The insert 43 is in close contact with the first inclined surface of the corresponding clamping plate 31 through the second inclined surfaces. When the insert 43 moves to the right, it is used to open the two clamping plates 31 to fix the drum. Preferably, the outer wall of the clamping plate 31 is arc-shaped to prevent damage to the inner wall of the drum.

[0019] In practical applications, the number of clamping parts 3 is set according to needs. In this embodiment, four clamping parts 3 are provided on the roller 2 to accommodate rolls of different widths and to fix rolls of different widths. The method of fixing the roll is very simple. Just put the roll on the outer wall of the roller 2, and then the operator rotates the knob 411 to make the screw 41 rotate. Because the screw 41 is rotatably connected to the nearest insert 43, when the screw 41 rotates, it will cause the four inserts 43 and the two straight plates 44 to move together toward the support plate 11. The inserts 43 will open the two clamping plates 31, and the clamping plates 31 will protrude from the through hole 21, thereby fixing the inner wall of the roll. After winding is completed, the operator rotates the knob 411 in the opposite direction. The clamping plates 31 lose the compression of the inserts 43 and retract back into the through hole 21 under the action of the spring 33, so as to replace the roll. One point to note is that when the knob 411 is rotated in the opposite direction, the insert 43 will gradually disengage from between the two clamps 31. To prevent the insert 43 from disengaging excessively, the length of the straight plate 44 can be adjusted. Figure 3 From this perspective, the insert 43 is not completely detached from the clamp 31, and the second inclined surface of the insert 43 is in close contact with the first inclined surface of the clamp 31. The straight plate 44 is in close contact with the sealing plate 42. The sealing plate 42 can stop the straight plate 44, indicating to the staff that the reverse rotation knob 411 has been completed.

[0020] In order to quickly move the drum to a specific position on roller 2, this embodiment takes the following measures: such as Figure 4 , Figure 5 As shown, the device also includes a positioning ring 5, which is sleeved on the outer periphery of the roller 2. The positioning ring 5 is located between the innermost clamping plate 31 and the support plate 11. The roller 2 has through grooves 22 at two symmetrical positions on its side wall. The straight plate 44 has an extension plate 441 at one end facing the support plate 11. The extension plate 441 is slidably fitted in the corresponding through groove 22 and is connected to the inner wall of the positioning ring 5.

[0021] Instructions for use: The operator places the roll onto the outer wall of roller 2, with one end of the roll pressed tightly against the positioning ring 5. Then, rotating knob 411 causes the four inserts 43 and two straight plates 44 to move together toward the support plate 11. On one hand, the inserts 43 will open the two clamps 31, thus fixing the roll. On the other hand, the positioning ring 5 also moves toward the support plate 11 along with the straight plates 44, thus moving the positioning ring 5 away from the roll to make room for material winding. Imagine if the positioning ring 5 were fixed to the outer wall of roller 2, then one end of the roll would be pressed tightly against the positioning ring 5, allowing for quick determination of the roll's position. However, during the winding process, friction may occur between the roll and the positioning ring 5, and between the material and the positioning ring 5. Therefore, in this embodiment, the positioning ring 5 is connected to the straight plates 44. The positioning ring 5 is used to quickly determine the position of the roll, and then the positioning ring 5 can move with the straight plates 44, thus moving the positioning ring 5 away from the roll.

Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
