Description

Technical Field

[0001] This utility model belongs to the field of plastic film production technology, and specifically relates to a take-up roller for plastic film processing. Background Technology

[0002] In the plastic film production process, the winding roller is a core component, and its performance directly affects the film winding efficiency and finished product quality.

[0003] The existing winding roller adjustment scheme has the problem that the movement of the limit blocks on both sides is not synchronized during the adjustment process, which can easily cause positional deviations. This results in uneven winding of the film edges, requiring manual secondary calibration, which significantly reduces production efficiency. Utility Model Content

[0004] This utility model addresses the problems in the prior art by providing a take-up roller for plastic film processing. The specific technical solution is as follows:

[0005] A take-up roller for plastic film processing includes a roller body assembly, a fixed side plate, and a mounting side plate. The roller body assembly has a roller surface structure extending axially, with its first end connected to the fixed side plate and its second end connected to the mounting side plate.

[0006] The mounting side plate is provided with an axially adjustable limiting component, which includes: an annular limiting member surrounding the roller surface structure and an adjustment mechanism symmetrically arranged on both sides of the annular limiting member;

[0007] Each adjustment mechanism includes: a transmission rod fixedly connected to an annular limiting member, and a sliding guide mechanism disposed in the mounting side plate, which includes a guide extending in the adjustment direction and a sliding member slidably disposed thereon, the guide being installed in a limiting groove opened in the side wall of the mounting side plate;

[0008] The locking device connecting the sliding member and the transmission rod includes multiple positioning parts disposed on the transmission rod and a selective engagement part disposed on the sliding member. The selective engagement part is connected to the sliding member by a pull rod and is pulled. The end of the positioning part away from the annular limiting member is connected to a push plate for limiting and acting on an elastic reset element of the sliding member to maintain the engagement state of the selective engagement part and the positioning part.

[0009] As a further technical solution of this utility model, the annular limiting member and the mounting side plate are elastically connected by an elastic connector.

[0010] As a further technical solution of this utility model, the working surfaces of the annular limiting member and the fixed side plate are both provided with a first elastic protective layer and a second elastic protective layer.

[0011] As a further technical solution of this utility model, the roller assembly includes: a roller body with multiple independent air pressure chambers inside and an air pressure control device connected to the air pressure chambers, for adjusting the internal pressure of each air pressure chamber.

[0012] As a further technical solution of this utility model, the contact interface between the annular limiting member and the roller surface structure is provided with a rolling guide mechanism.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this application, the position of the selective coupling component inserted into different positioning parts is adjusted to adjust the position of the annular limiting component on the roller body. This ensures that the annular limiting component remains in the same vertical and horizontal state during the adjustment process, avoiding positional deviations that could cause uneven film edge winding and ensuring the winding efficiency of the winding roller.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Figure 1 A schematic diagram of the overall internal structure of a take-up roller used in plastic film processing is shown. Figure 1 The roller assembly includes a roller body assembly, a fixed side plate 2, and a mounting side plate 6. The roller body assembly has a roller surface structure that extends axially, with its first end connected to the fixed side plate 2 and its second end connected to the mounting side plate 6.

[0021] The mounting side plate 6 is provided with an axially adjustable limiting component, which includes: an annular limiting member 8 arranged around the roller surface structure and an adjustment mechanism symmetrically arranged on both sides of the annular limiting member 8.

[0022] Each adjustment mechanism includes: a transmission rod 10 fixedly connected to the annular limiting member 8, and a sliding guide mechanism disposed in the mounting side plate 6, which includes a guide member 16 extending in the adjustment direction and a sliding member 15 slidably disposed thereon, the guide member 16 being installed in a limiting groove 18 opened in the side wall of the mounting side plate 6;

[0023] The locking device connecting the sliding member 15 and the transmission rod 10 includes multiple positioning parts 11 disposed on the transmission rod 10 and selective engagement parts 13 disposed on the sliding member 15. The selective engagement parts 13 and the sliding member 15 are connected and pulled by a pull rod 14. The end of the positioning part 11 away from the annular limiting member 8 is connected to a push plate 12 for limiting. An elastic reset element 17 acts on the sliding member 15 to maintain the engagement state between the selective engagement parts 13 and the positioning parts 11. By adjusting the position of the selective engagement parts 13 inserted into different positioning parts 11, the position of the annular limiting member 8 on the roller body 1 is adjusted, thereby ensuring that the annular limiting member 8 remains in the same vertical and horizontal state during the adjustment process, avoiding the occurrence of positional deviation that causes uneven film edge winding, and ensuring the winding efficiency of the winding roller.

[0024] Figure 2 It shows Figure 1 A schematic diagram of the adjustment mechanism is shown. The annular limiting member 8 and the mounting side plate 6 are elastically connected by an elastic connector 7. Under the elastic connection of the elastic connector 7, the consistency of the movement of the annular limiting member 8 on the roller body 1 is further ensured. The working surfaces of the annular limiting member 8 and the fixed side plate 2 are provided with a first elastic protective layer 5 and a second elastic protective layer 9. Under the protective design of the first elastic protective layer 5 and the second elastic protective layer 9, the film is prevented from being scratched. The roller assembly includes: a roller body 1 with multiple independent air pressure chambers 3 inside and an air pressure control device 4 connected to the air pressure chambers 3, which is used to adjust the internal pressure of each air pressure chamber 3. The air pressure chambers 3 are evenly distributed on the surface of the take-up roller. The air pressure in the air pressure chambers 3 is adjusted by the air pressure control device 4, so that the surface of the roller body 1 produces a slight deformation to adapt to the film tension. A rolling guide mechanism 19 is provided at the contact interface between the annular limiting member 8 and the roller surface structure. Under the rolling movement of the rolling guide mechanism 19, the frictional resistance of the annular limiting member 8 sliding on the roller body 1 is reduced, ensuring the smooth and efficient operation of the device.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
