Description

Technical Field

[0001] This utility model belongs to the field of auxiliary production technology for slitting machines, and specifically relates to a waste edge collection device for slitting machines. Background Art

[0002] A slitting machine is a mechanical device used to cut wide materials such as paper, film, and non-woven fabric into narrow rolls. It is widely used in industries such as papermaking, printing and packaging, and wire and cable manufacturing. The working principle of a slitting machine mainly relies on a magnetic powder clutch as a resistance device. The resistance generated by the magnetic powder clutch is adjusted by controlling the output DC voltage of the system, thereby achieving precise control of the material tension. This design ensures stable operation of the equipment under high-speed conditions. During the operation of the slitting machine, excess waste edges are generated when the wide rolls of material are cut into multiple narrow rolls. These waste edges need to be recycled to prevent them from becoming entangled inside the slitting machine and causing mechanical failure.

[0003] In the current technology, waste edge collection rollers are generally installed on cantilever shafts. In continuous production, in order to connect and recycle waste edges, the length of the collection roller is increased. However, the weight of the collection roller is also increased by the length of the collection roller, and the cantilever shaft will bear a large torque, which will increase the probability of deformation and mechanical failure, resulting in poor practicality.

[0042] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0043] Please refer to the following: Figures 1 to 4The waste edge collection device for a slitting machine provided by this utility model will now be described. The waste edge collection device for a slitting machine includes a frame 10, a drive mechanism 20, and a positioning support mechanism 30. The drive mechanism 20 is mounted on the frame 10 and has a cantilever extension that extends horizontally and is fitted onto a receiving roller. The rotation axis of the cantilever extension is horizontally positioned. The positioning support mechanism 30 has a positioning structure 31 and a support structure 32. The positioning structure 31 is fitted onto the cantilever extension, and the positioning structure 31, the cantilever extension, and the frame 10 together form an adjustable-length mounting position. One end of the support structure 32 is mounted on the frame 10, and the other end is connected to the extended end of the cantilever extension, providing support for the cantilever extension.

[0044] The waste edge collection device for slitting machines provided in this embodiment, compared with the prior art, features a frame 10 that can support the drive mechanism 20 and the positioning support mechanism 30. The drive mechanism 20 has a horizontally extending cantilever for the receiving roller to be fitted, allowing the receiving roller to rotate with the cantilever. The positioning support mechanism 30, through a positioning structure 31, together with the cantilever and frame 10, forms an adjustable-length mounting position. The cantilever is supported by a support structure 32 located at its extended end. The positioning structure 31 allows for positioning of the receiving roller as its length increases, and the support structure 32 supports the cantilever, reducing the probability of deformation and mechanical failure, thus improving practicality.

[0045] In some embodiments, the drive mechanism 20 described above may employ, for example... Figure 1 , Figure 4 The structure shown. See also Figure 1 , Figure 4 The drive mechanism 20 includes a cantilever shaft 21 and a drive motor 22. The cantilever shaft 21 is rotatably mounted on the frame 10, with its rotation axis horizontally positioned, and the cantilever shaft 21 is a cantilever extension. The drive motor 22 is used to drive the cantilever shaft 21 to rotate.

[0046] The cantilever shaft 21 can be understood as a motor-driven rotating shaft mounted on the frame 10, with the rotation axis of the shaft set horizontally. The drive motor 22 can be a servo motor. A servo motor is a high-precision motor control system that is widely used in applications requiring precise control of position, speed, and acceleration. Servo motors are existing technology and will not be discussed in detail here.

[0047] In some embodiments, the positioning structure 31 described above can be as follows: Figure 1 , Figure 2 The structure shown. See also Figure 1 , Figure 2The positioning structure 31 includes a sliding top plate 311, a threaded ring 312, and a spring 313.

The sliding top plate 311, the cantilever shaft 21, and the frame 10 together form the mounting position. The threaded ring 312 is sleeved on the cantilever shaft 21 and threadedly connected to it. The threaded ring 312 and the sliding top plate 311 are spaced apart, with the sliding top plate 311 positioned between the threaded ring 312 and the take-up roller. The spring 313 is positioned between the sliding top plate 311 and the threaded ring 312 to ensure that the sliding top plate 311 always has a tendency to move towards the take-up roller.

[0048] The extended end of the cantilever shaft 21 is provided with an external thread for threaded connection of the threaded ring 312.

[0049] A spring 313 is provided between the sliding top plate 311 and the threaded ring 312. The threaded ring 312 is threadedly connected to the cantilever shaft 21. The sliding top plate 311 is located between the threaded ring 312 and the take-up roller. Under the action of the spring 313, the sliding top plate 311 always tends to move towards the take-up roller and press against the take-up roller.

[0050] In some embodiments, the positioning structure 31 described above can be as follows: Figure 1 , Figure 2 The structure shown. See also Figure 2 , Figure 4 The positioning structure 31 includes a fixing block 321, a hinged cantilever 322, and a support and locking assembly 323. The fixing block 321 is fixed to the frame 10 and located below the extended end of the cantilever shaft 21. One end of the hinged cantilever 322 is hinged to the fixing block 321, and the other end extends outward. The hinge axis of the hinged cantilever 322 is parallel to the axis of the cantilever shaft 21. The support and locking assembly 323 is located at the extended end of the hinged cantilever 322 and is used to connect to the cantilever shaft 21 and lock the connection with the cantilever shaft 21.

[0051] The fixed block 321 is located below the extended end of the cantilever shaft 21. The hinged cantilever 322 is hinged to the fixed block 321 and can rotate on the fixed block 321. When the take-up roller is being replaced, the hinged cantilever 322 is in a horizontal state. When the take-up roller is working, the hinged cantilever 322 is in a vertical state. The extended end of the cantilever shaft 21 is locked and supported by the support locking component 323 provided at the extended end.

[0052] In some embodiments, the aforementioned support locking component 323 may employ, as follows: Figure 1 , Figure 2 The structure shown. See also Figure 1 , Figure 2The support locking assembly 323 includes a fixed semi-annular ring 3231 and a rotating semi-annular ring 3232. The fixed semi-annular ring 3231 is fixedly mounted on the extended end of the hinged cantilever 322 and integrally connected with the hinged cantilever 322. The axis of the fixed semi-annular ring 3231 is collinear with the axis of the cantilever shaft 21, and the fixed semi-annular ring 3231 has a first notch for the cantilever shaft 21 to be engaged. The rotating semi-annular ring 3232 is rotatably mounted on the fixed semi-annular ring 3231, and its rotation axis is collinear with the axis of the fixed semi-annular ring 3231. The rotating semi-annular ring 3232 has a second notch for the cantilever shaft 21 to be engaged.

[0053] The fixed semi-annular ring 3231 can be understood as a C-shaped block fixed on the extended end of the hinged cantilever 322. The rotating semi-annular ring 3232 can be understood as the C-shaped block rotatably connected to the fixed semi-annular ring 3231. When the take-up roller is replaced, the rotating semi-annular ring 3232 is rotated to open the notch of the fixed semi-annular ring 3231, so that the hinged cantilever 322 and the cantilever shaft 21 are in contact and connected. When the take-up roller is working, the cantilever shaft 21 enters the notch of the fixed semi-annular ring 3231, and the rotating semi-annular ring 3232 locks the cantilever shaft 21 in the notch.
