Description

Technical Field

[0001] The utility model relates to the technical field of plastic film slitting machines, in particular to a plastic film slitting machine for tensioning and slitting. Background Technique

[0002] As is well known, a film is a thin and soft transparent sheet made of plastic, adhesive, rubber or other materials. The scientific explanation of a film is: a two-dimensional material formed by atoms, molecules or ions deposited on the surface of a substrate. After the film leaves the factory, it needs to be cut into appropriate sizes, so a plastic film slitting machine is required. In order to ensure that the film does not shift during cutting, the existing slitting machine is provided with a clamping mechanism to fix the film. When fixing the film, the film is slightly pulled to make the film in a tensioned state, and then the film can be cut.

[0003] When the existing plastic film slitting machine for tensioning and slitting cuts the film, it is generally placed on a cutting board for cutting or directly placed on a table for cutting. However, the existing cutting board is generally fixed on the equipment. After long-term use, the cutting board will be worn. Since it is not convenient to replace, the damaged cutting board will affect the smoothness of the cutting process, resulting in a reduction in production efficiency. Moreover, on the surface of the damaged cutting board, the cutting tool will be unevenly stressed, resulting in a decline in the cutting effect. Content of the Utility Model

[0007] To achieve the above object, the present utility model provides the following technical solutions: a plastic film slitter for tensioning and slitting, comprising a bottom plate, a support seat, a cutting mechanism, a cutting plate, a connecting mechanism, a limiting mechanism and a clamping mechanism. The support seat is arranged at the bottom of the bottom plate, and there are several support seats. The cutting mechanism is arranged on the top of the bottom plate. The cutting plate is connected to the bottom plate through the connecting mechanism. The connecting mechanism includes a slot and a T-shaped block. The slot is opened on the bottom plate, and one end of the T-shaped block passes through the slot and is connected to the cutting plate. The limiting mechanism includes a chute, a slider, a bearing, a rotating block, a through groove, a spring and a clamping block. The bearing is arranged on the T-shaped block, one end of the rotating block is rotatably connected to the bearing, and the other end of the rotating block abuts against the bottom plate. The chute is opened on the T-shaped block, one end of the slider is slidably connected to the chute, and the other end of the slider abuts against the rotating block. The through groove is opened on the rotating block, one end of the spring is connected to the inner wall of the through groove, the other end of the spring is connected to one end of the clamping block, and the other end of the clamping block extends into the slider. The clamping mechanism includes an electric telescopic rod and a pressing plate. One end of the electric telescopic rod is connected to the top of the bottom plate, and the other end of the electric telescopic rod is connected to the pressing plate. There are two clamping mechanisms.

[0008] In order to improve stability, the present utility model is improved in that the two clamping mechanisms are symmetrically arranged.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the present utility model provides a plastic film slitter for tensioning and slitting, which has the following beneficial effects:

[0015] In this tree-planting hole-digging device, the cutting plate in this structure is detachably connected to the bottom plate through the cooperation of the connecting mechanism and the limiting mechanism. When the cutting plate is in contact with the cutting tool for a long time and wears out, controlling the connecting mechanism and the limiting mechanism can timely replace the new cutting plate. Different from the traditional cutting plate directly welded to the bottom plate, it can avoid the worn cutting plate affecting the smoothness of the cutting process and reducing the production efficiency. It can also prevent the cutting tool from contacting the surface of the damaged cutting plate, resulting in uneven stress on the tool and a decline in the cutting effect.

Detailed Description of the Preferred Embodiment

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4, A plastic film slitter that tightens and cuts, comprising a bottom plate 1, a support base 2, a cutting mechanism 3, a cutting plate 4, a connecting mechanism 5, a limiting mechanism 8 and a clamping mechanism 16. The support base 2 is arranged at the bottom of the bottom plate 1, and there are several support bases 2. The cutting mechanism 3 is arranged on the top of the bottom plate 1. The cutting plate 4 is connected to the bottom plate 1 through the connecting mechanism 5. The connecting mechanism 5 includes a slot 6 and a T-shaped block 7. The slot 6 is opened on the bottom plate 1, and one end of the T-shaped block 7 passes through the slot 6 and is connected to the cutting plate 4. The limiting mechanism 8 includes a chute 9, a slider 10, a bearing 11, a rotating block 12, a through slot 13, a spring 14 and a clamping block 15. The bearing 11 is arranged on the T-shaped block 7, and one end of the rotating block 12 is rotatably connected to the bearing 11. The other end of the rotating block 12 abuts against the bottom plate 1. The chute 9 is opened on the T-shaped block 7, and one end of the slider 10 is slidably connected to the chute 9. The other end of the slider 10 abuts against the rotating block 12. The through slot 13 is opened on the rotating block 12. One end of the spring 14 is connected to the inner wall of the through slot 13, and the other end of the spring 14 is connected to one end of the clamping block 15. The other end of the clamping block 15 extends into the slider 10. The clamping mechanism 16 includes an electric telescopic rod 17 and a pressing plate 18. One end of the electric telescopic rod 17 is connected to the top of the bottom plate 1, and the other end of the electric telescopic rod 17 is connected to the pressing plate 18. There are two clamping mechanisms 16.

[0023] During use, first place the device in a designated position, and then the device can be supported by the support base 2 at the bottom of the base plate 1. When the device needs to be used, first place the plastic film to be cut on the cutting plate 4, adjust the position to be cut, and then slightly pull both ends of the plastic film to make the plastic film flat and in a taut state. It should be noted here that the tension force should not be too large to prevent the plastic film from deforming. A slight tension is sufficient. Then start the electric telescopic rod 17 to press the pressing plate 18 against the plastic film, and then the plastic film can be cut through the cutting assembly. The reserved position between the two clamping mechanisms 16 is relatively small, so that both sides of the small-sized plastic film can also be clamped. The cutting assembly in the text includes components such as a mounting plate, a chute 9, a slider 10, a threaded rod, a motor, an electric push rod, and a cutting knife, which will not be specifically described here. The reserved position between the two clamping mechanisms 16 enables the cutting mechanism 3 to pass through and contact the plastic film. After cutting is completed, control the clamping mechanism 16 to stop limiting the plastic film, and then the plastic film can be taken out. When the cutting plate 4 is used for a long time and comes into long-term contact with the cutting knife, and wear appears on the surface of the cutting plate 4 and needs to be replaced, first, the staff inserts two fingers into the through groove 13, pinches both ends of the clamping block 15, and lifts the clamping block 15 upward to make the spring 14 contract, so that the clamping block 15 is separated from the slider 10. Then push the slider 10 on the chute 9 to separate the slider 10 from the rotating block 12. Then rotate the rotating block 12 on the bearing 11 to separate the rotating block 12 from the base plate 1. Then pull the cutting plate 4 to separate the T-shaped block 7 from the slotted groove 6, and the cutting plate 4 can be separated from the base plate 1. Then a new cutting plate 4 can be replaced. The size of the through groove 13 is large enough for the staff to insert their fingers inside. The sizes of all components in the text are not specifically limited and need to be produced according to the actual situation.

[0024] The stability of the above-mentioned clamping mechanism 16 is relatively poor. To solve this problem, in this embodiment, the two clamping mechanisms 16 are symmetrically arranged.

[0025] The wear resistance of the bottom of the above-mentioned support base 2 is relatively poor. The bottom of the support base 2 is in contact with the ground for a long time and is prone to wear. To solve this problem, in this embodiment, wear-resistant layers are provided at the bottoms of several support bases 2, and the tops of the wear-resistant layers are fixedly connected to the bottoms of the support bases 2.

[0026] To improve the wear resistance effect, in this embodiment, wear-resistant lines are provided at the bottoms of the wear-resistant layers, and several wear-resistant lines are provided.

[0027] The stability of the above-mentioned slider 10 when sliding on the chute 9 is relatively poor. To solve this problem, in this embodiment, the slider 10 matches the chute 9.

[0028] The strength of the above-mentioned bottom plate 1 is poor, and the bottom plate 1 is prone to breakage after long-term use. To solve this problem, in this embodiment, the bottom plate 1 is made of alloy steel.

[0029] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
