Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tape processing, in particular to a roll cutting device. Background Art

[0002] The tape is composed of two parts: a base material and an adhesive. It connects two or more unconnected objects together through bonding. When the tape is being processed, the tape roll tube needs to be cut for winding the tape. Currently, the tape roll tube is processed by a slitting machine.

[0003] When the existing slitting machine is in use, multiple sets of cutting heads are installed on the surface of the slitting machine. When the slitting machine is not in use, the cutting heads will be exposed to the outside for a long time, which is easily affected by the air and causes oxidation and rust. Therefore, we propose a roll cutting device to solve the above problem. Utility Model Content

[0009] Preferably, the guide column is set to a cylindrical shape, and a through hole compatible with the guide column is opened inside the driving plate. The surface size of the limiting plate is larger than the inner wall size of the through hole. By making the surface size of the limiting plate larger than the inner wall size of the through hole, the function of the limiting driving plate can be facilitated.

[0015] 2. The device can move the telescopic pin inside the driving plate by pulling the pulling rod. When the telescopic pin is away from the inside of the guide column, the driving plate can be moved along the surface of the guide column, so that the protective mechanism is away from the slitting head to avoid affecting the use of the slitting head. When the driving plate needs to be fixed, the pulling rod is released, and the telescopic pin can be inserted into the guide column through the elastic force of the reset spring to fix the driving plate.

[0027] Further, see Figure 3 and Figure 4 It can be known that the limiting mechanism 6 includes a driving plate 61, the driving plate 61 is sleeved on the surface of the guide column 51, and a groove is opened inside the driving plate 61, the inner wall of the groove is welded to one end of the reset spring 62, and the other end of the reset spring 62 is welded to the surface of the telescopic pin 63, and a pulling rod 64 is fixedly connected to the top of the telescopic pin 63. A through groove adapted to the pulling rod 64 is opened on the upper surface of the driving plate 61, so that the pulling rod 64 can be moved. Through the elastic force of the reset spring 62 itself, it can facilitate the pushing of the telescopic pin 63.

[0028] Further, see Figure 3 and Figure 4 It can be known that the guide column 51 is set to be cylindrical, and a through hole compatible with the guide column 51 is opened inside the driving plate 61. The surface size of the limit plate 52 is larger than the inner wall size of the through hole. The limit plate 52 can move along the surface of the guide column 51 through the through hole opened inside the driving plate 61.

[0029] Further, see Figure 3 and Figure 4 It can be known that the telescopic pin 63 is inserted in the groove and fixedly connected to the limit slider 65 on both sides of one end, and the inner wall of the groove is provided with a sliding groove adapted to the limit slider 65. By moving the telescopic pin 63 in the groove, the limit slider 65 can slide in the sliding groove, thereby playing the role of limiting and guiding the telescopic pin 63.
