Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tape processing, in particular to a 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. A layer of adhesive is coated on its surface. The earliest adhesives came from animals and plants. When the tape is being processed, a slitting machine is used to cut the paper tube.

[0003] When the existing slitting machine is in use, the paper tube will be directly mounted on the rotating shaft. Since the paper tube will be driven by the rotating shaft to rotate at high speed when cutting, the paper tube is easily offset during the cutting process, causing it to fall or have an uneven cut. Therefore, we propose a cutting device to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a cutting device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A cutting device comprises a cutting machine body, a motor drive box is installed above the cutting machine body, and the output ends of the motor drive box are respectively connected to the cutting head and the driving shaft, the outer end of the driving shaft is inserted with a plug-in mechanism, and a limiting mechanism is fixed on the inner side of the plug-in mechanism, and an extrusion mechanism is fixed on the outer side of the plug-in mechanism.

[0007] Preferably, the plug-in mechanism includes a connecting stud, the outer end of the driving shaft is threadedly connected to the connecting stud, and the outer end of the connecting stud is fixedly connected to a limiting disk, and a connecting column is installed on the inner side of the connecting stud through a bearing. The connecting stud can be conveniently operated by threading the driving shaft and the connecting stud.

[0008] Preferably, a groove matching the connecting stud is provided inside the driving shaft, and the surface diameter of the limiting plate is larger than the surface diameter of the driving shaft. By the surface diameter of the limiting plate being larger than the surface diameter of the driving shaft, the paper tube can be limited.

[0009] Preferably, the limiting mechanism includes a fixed seat, the end of the connecting column is fixedly connected to the fixed seat, and a groove is provided on the surface of the fixed seat, an articulation shaft is hinged on the inner wall of the groove, and an articulation column is sleeved on the surface of the articulation shaft, and the groove provided on the surface of the fixed seat can facilitate the installation of the articulation shaft and the articulation column.

[0010] Preferably, a torsion spring is sleeved on the surface of the articulated shaft, and a torsion spring is welded between the groove and the articulated clamping column, so that the articulated clamping column can be easily reset by the torsion spring.

[0011] Preferably, the extrusion mechanism includes an adjusting stud, the outer end of the limit plate is installed with the adjusting stud through a bearing, and the surface of the adjusting stud is threadedly sleeved with a driving block, the surface of the driving block is fixedly connected with a driving column, and the end of the driving column is fixedly connected to one end of the pushing rod, and the other end of the pushing rod is fixedly connected with an extrusion block, and by rotating the adjusting stud, the driving block can drive the driving column to move, thereby facilitating the extrusion block to squeeze the paper tube.

[0012] Preferably, the cross-section of the extrusion block is set to be arc-shaped, and a buffer pad is glued to the surface of the extrusion block. The surface of the buffer pad is provided with anti-slip grooves. The anti-slip grooves on the surface of the buffer pad can increase the friction between the buffer pad and the paper tube.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The device drives the driving shaft to rotate through the motor drive box, so that the cutting head can cut the tape paper tube set on the surface of the driving shaft. After cutting, the limit plate is rotated to make the connecting stud drive the connecting column to be pulled out from the inside of the driving shaft. Through the movement of the connecting column, the fixed seat can drive the hinge shaft to move, so that the paper tube after cutting on the surface of the driving shaft can be removed and stacked conveniently. At the same time, when the paper tube is cut, the limit plate can play a blocking role to prevent the paper tube from sliding off the surface of the driving shaft.

[0015] 2. The device can move the driving block along its surface by rotating the adjusting stud. Through the movement of the driving block, the driving column can drive the push rod to move in the limit plate, so that the extrusion block drives the buffer pad to contact the side of the paper tube, and cooperates with the hinged clamping column to squeeze the paper tube to limit the position, avoiding shaking when cutting the paper tube and causing uneven incision.

The connecting column 53 is installed as a bearing, so that the limit plate 52 can rotate.

[0027] Further, see Figure 2 and 3 It can be known that a groove compatible with the connecting stud 51 is opened inside the driving shaft 4, and the surface diameter of the limiting plate 52 is larger than the surface diameter of the driving shaft 4. Through the groove opened inside the driving shaft 4, the connecting column 53 can be easily inserted into the groove.

[0028] Further, see Figure 2 and Figure 3It can be known that the limiting mechanism 6 includes a fixed seat 61, the end of the connecting column 53 is fixedly connected to the fixed seat 61, and a groove is provided on the surface of the fixed seat 61, a hinge shaft 62 is hinged on the inner wall of the groove, and a hinge clamping column 63 is sleeved on the surface of the hinge shaft 62. The hinge clamping column 63 moves in the groove provided on the surface of the fixed seat 61, so as to facilitate the insertion and removal of the paper tube.

[0029] Further, see Figure 2 and Figure 3 It can be known that a torsion spring 64 is sleeved on the surface of the hinge shaft 62 , and a torsion spring 64 is welded between the groove and the hinge clamping column 63 , so that the hinge clamping column 63 can be easily reset by the torsion spring 64 .

[0030] Further, see Figure 2 and Figure 4 It can be known that the extrusion mechanism 7 includes an adjusting stud 71, and the outer end of the limit plate 52 is installed with the adjusting stud 71 through a bearing. The adjusting stud 71 is installed through the bearing, so that the adjusting stud 71 can rotate on the surface of the limit plate 52, and the surface of the adjusting stud 71 is threadedly sleeved with a driving block 72, and the surface of the driving block 72 is fixedly connected with a driving column 73.
