Description

Technical Field

[0001] This utility model belongs to the field of PP film slitting and processing technology, and more specifically, it relates to a PP film slitting machine with anti-deviation function. Background Technology

[0002] A PP film slitting machine is a device specifically designed to slit large rolls of polypropylene (PP) film into smaller rolls or rolls of a specific width. PP film is a widely used material in packaging, electronics, and medical industries, characterized by its lightweight, transparency, and durability. The slitting machine precisely cuts large rolls of film to meet the needs of different customers, such as segmenting to specific widths or lengths. Chinese patent application number CN202121222039.X discloses a blade holder correction device for a PU film cutting machine. This device includes a cutting machine support; an unwinding rod rotatably mounted on the support; an unwinding roller fixedly sleeved on the unwinding rod; a connecting rod rotatably mounted on the support; a connecting roller rotatably mounted on the support; a rotating mechanism mounted on the support; and a lifting mechanism mounted on the support. The blade holder correction device of the PU film cutting machine provided by this utility model has the advantages of avoiding tearing of PU film, reducing the deviation caused by film cutting, facilitating the adjustment of the deviation, and making the cutting more precise.

[0003] Based on the above, the inventors have discovered the following problems: the above-mentioned patent avoids the problem of film cutting deviation in a certain aspect, but it cannot solve the problem that the elasticity of the material being cut during the cutting process leads to insufficient tension, which causes the film to deviate during the cutting process, resulting in a decrease in the film cutting quality. Furthermore, the position of the film on the winding roller will also cause the overall cutting position of the film on the machine to shift, affecting the film cutting effect.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a PP film slitting machine with anti-deviation function, in order to achieve a more practical value. Utility Model Content

[0035] The limiting assembly comprises an electric telescopic rod 5, a moving cavity 6 and a connecting frame 8. The right supporting seat 2 and the left supporting seat 1 are respectively provided with the moving cavity 6 and the electric telescopic rod 5. The output end of the electric telescopic rod 5 extends into the moving cavity 6 and is connected with both ends of the connecting frame 8.

One side of the pair of arc-shaped members is provided with a hinge. The other side of the pair of arc-shaped members is provided with a lock 30.

[0036] Before the device operates, the electric telescopic rod 5 drives the connecting frame 8 to move vertically downward to the direction of the electric material collecting roller one 9 and the electric material collecting roller two 10. At this time, the lock 30 is in an open state. When the annular hole 31 is clamped with the electric material collecting roller one 9 and the electric material collecting roller two 10, the lock 30 is closed, so that the annular hole 31 is fixed in the vertical direction on the electric material collecting roller one 9 and the electric material collecting roller two 10. At this time, the limiting member 15 and the annular hole 31 form a baffle, which can limit the pp film to be wound on the electric material collecting roller one 9 and the electric material collecting roller two 10, so as to avoid the deviation of the pp film winding and the whole cutting. The position of the connecting plate 27 in the rectangular cavity 24 can be adjusted by rotating the bolt 26, so that the extension length of the fixing member 13 after passing through the through hole 28 can be adjusted. The fixing member 13 is retracted into the through hole 28 by rotating the bolt 26. Then, the moving ring 14 is pushed to the required position. Then, the fixing member 13 is extended out of the through hole 28 by reversely rotating the bolt 26. One of the fixing members 13 can be clamped with the clamping hole 12 to fix the position of the moving ring 14, so that the position of the limiting member 15 can be adjusted, and the pp film cut to different widths can be limited.

[0037] The cutting assembly comprises a supporting shaft 4 and an electric cutting knife 20. The both ends of the supporting shaft 4 are arranged on the left supporting seat 1 and the right supporting seat 2 respectively. The supporting shaft 4 is provided with a plurality of electric cutting knives 20.

[0038] Through the design of the cutting assembly, the pp film between the electric material conveying roller 3 and the electric limiting roller 7 can be cut.

[0039] The electric feeding roller 3, the supporting shaft 4, the electric material collecting roller one 9, the electric limiting roller 7 and the electric material collecting roller two 10 are horizontally arranged.

[0040] The inner diameter length of the annular hole 31 is greater than the diameter length of the electric material collecting roller one 9 and the electric material collecting roller two 10, and the ball 29 is in close contact with the surface of the electric material collecting roller one 9 and the electric material collecting roller two 10.

[0041] When the annular hole 31 is engaged with the electric material collecting roller one 9 or the electric material collecting roller two 10, the rotation of the electric material collecting roller one 9 and the electric material collecting roller two 10 can be avoided by the design of the ball 29.

[0042] The specific use and effect of the embodiment are as follows:

[0043] Firstly, the integrity of the device is checked, and then the device is installed on a horizontal plane. Before the device is operated, the electric telescopic rod 5 is started to drive the connecting frame 8 to move vertically downward to the direction of the electric material collecting roller one 9 and the electric material collecting roller two 10. At this time, the lock buckle 30 is in an open state. When the annular hole 31 is engaged with the electric material collecting roller one 9 and the electric material collecting roller two 10, the lock buckle 30 is closed to fix the annular hole 31 vertically on the electric material collecting roller one 9 and the electric material collecting roller two 10. At this time, the baffle composed of the limiting piece 15 and the annular hole 31 can limit the pp film to be wound on the electric material collecting roller one 9 and the electric material collecting roller two 10, so as to avoid the deviation of the pp film winding and cutting.

[0044] The position of the connecting plate 27 in the rectangular cavity 24 can be adjusted by rotating the bolt 26, so that the extension length of the fixed piece 13 after passing through the through hole 28 can be adjusted. The fixed piece 13 is retracted into the through hole 28 by rotating the bolt 26, and then the moving ring 14 is pushed to the required position. Then the bolt 26 is reversely rotated to make the fixed piece 13 extend out of the through hole 28. A certain fixed piece 13 can be engaged with the clamping hole 12 to fix the position of the moving ring 14. The position of the limiting piece 15 can be adjusted, so as to limit the pp film of different widths after cutting.

[0045] The electric motor 22 is started to drive the screw rod 23 to rotate, drive the connecting block 18 to move vertically on the screw rod 23, and drive the electric material collecting roller one 9 and the electric material collecting roller two 10 to move vertically. In combination with the electric limiting roller 7, the tension of the pp film is adjusted, so as to avoid insufficient tension of the pp film in the cutting process, affect the cutting and winding effect of the pp film, and improve the cutting and winding quality of the pp film. The vertical movement of the electric material collecting roller one 9 and the electric material collecting roller two 10 can be limited and guided by the design of the guide shaft 17, the connecting block 18 and the left moving cavity 16, so that the electric material collecting roller one 9 and the electric material collecting roller two 10 can move smoothly.

[0046] The device is novel in overall design and simple in structure, and is worth being widely used.
