It can be attached to the surface of an object to prevent direct contact between objects, protect objects, and prevent damage caused by friction and bumps. It is widely used in many fields. During the processing of plastic film, it is necessary to cut the size of the plastic film.

[0003] In order to solve the cutting problem, a certain plastic film processing in the market adopts an automatic cutting design, which has a certain market share.

Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that the plastic film is prone to displacement and sliding, which affects the cutting accuracy and makes the positioning effect of the cutting device for processing the plastic film poor.

A cutting plate is fixedly connected to the inner wall of the cutting machine just below the cutting knife, a positioning plate is fixedly connected to one end of the cutting plate close to the storage table, a connecting block is symmetrically fixedly connected to the side end of the electric push plate just above the positioning plate, a telescopic rod is fixedly connected to the bottom end of the connecting block, a pressing plate is fixedly connected to the bottom end of the telescopic rod, a second sliding groove corresponding to the positioning plate is symmetrically carved on the inner wall of the cutting machine, the pressing plate is slidably connected to the second sliding groove, a plurality of rollers are rotatably connected to the inner wall of the cutting machine between the cutting knife and the discharge shaft, and the discharge shaft is laid on the top of the cutting plate and the positioning plate through the rollers.

[0007] In the above-mentioned processing positioning device, the plastic film can be automatically positioned before cutting, thereby avoiding displacement during cutting.

[0008] As a further improvement of the present application, sliders are fixedly connected to both ends of the pressing plate, and the sliders are engaged with the second sliding grooves.

[0009] As a further improvement of the present application, the pressing plate is made of solid iron material.

[0010] As a further improvement of the present application, the telescopic rod is composed of a short ring arranged outside a long cylinder, a spring is fixedly connected to the top end of the short ring, and the bottom end of the spring is fixedly connected to the long cylinder.

[0011] As another improvement of the present application, the distance between the cutting knife and the cutting plate is equal to the length of the short ring.

[0012] As another improved supplement of the present application, a second slide groove is cut at the top of the connecting plate, and the discharge shaft is engaged with the second slide groove.

[0013] In summary, this solution can be realized. When it is necessary to cut the plastic film, the baffle can be slid to adjust the distance between the baffle and the cutting machine according to the length of all cuttings. Then, the time difference of the cutting knife rising and falling can be set to keep it consistent with the cutting length. At this time, the driving roller drives the feeding shaft to rotate to feed the plastic film. When the plastic film moves to the cutting plate and the positioning plate, the electric push plate will be automatically turned on to drive the telescopic rod to move downward, so that the pressing plate will first contact the positioning plate to press the plastic film above to position it, and then continue to move downward. Through the telescopic adjustment of the telescopic rod, the cutting knife continues to move downward to contact the plastic film on the cutting board to cut it off. Then, the electric push plate is moved up to drive the cutting knife and the pressing plate to move away from the positioning plate and the cutting plate. The cut plastic film will automatically fall on the storage table and remain between the baffle and the cutting machine, effectively achieving the effect of automatically positioning the plastic film before cutting it, avoiding offset and dislocation during cutting.

[0020] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0021] The first implementation method:

[0022] Figure 1-2 A positioning device for processing plastic film is shown, comprising a cutting machine 1, a side end of the cutting machine 1 is fixedly connected to a storage table 2, a first slide groove 10 is symmetrically chiseled at the top of the storage table 2, a baffle 11 is slidably connected in the first slide groove 10, a connecting plate 16 is symmetrically fixedly connected to the end of the cutting machine 1 away from the storage table 2, a discharge shaft 3 is rotatably connected between the two connecting plates 16, a plastic film 4 is wound around the surface of the discharge shaft 3, a groove 7 is symmetrically chiseled at the top of the cutting machine 1 close to the storage table 2, an electric push plate 8 is slidably connected in the groove 7, a cutting knife 12 is fixedly connected to the bottom end of the electric push plate 8, and a cutting knife 12 is located directly below the cutting knife 12. A cutting plate 5 is fixedly connected to the inner wall of the cutting machine 1, and a positioning plate 6 is fixedly connected to one end of the cutting plate 5 close to the storage table 2. A connecting block 9 is symmetrically fixedly connected to the side end of the electric push plate 8 located directly above the positioning plate 6, and a telescopic rod 13 is fixedly connected to the bottom end of the connecting block 9, and a pressing plate 15 is fixedly connected to the bottom end of the telescopic rod 13. A second slide groove 14 corresponding to the positioning plate 6 is symmetrically excavated on the inner wall of the cutting machine 1, and the pressing plate 15 is slidably connected to the second slide groove 14. A plurality of rollers are rotatably connected to the inner wall of the cutting machine 1 located between the cutting knife 12 and the discharge shaft 3, and the discharge shaft 3 is laid on the top of the cutting plate 5 and the positioning plate 6 through the rollers.

[0023] The present invention can realize that when it is necessary to cut the plastic film 4, the baffle plate 11 can be slid according to the length of all cuttings to adjust the distance between the baffle plate 11 and the cutting machine 1, and then the time difference of the rise and fall of the cutting knife 12 can be set to keep it consistent with the cutting length. At this time, the driving roller drives the feeding shaft 3 to rotate so as to feed the plastic film 4. When the plastic film 4 moves to the cutting plate 5 and the positioning plate 6, the electric push plate 8 will be automatically turned on to drive the telescopic rod 13 to move downward, so that the pressing plate 15 will first contact with the positioning plate 6 to press the plastic film 4 above to position it, and then continue to move downward. Through the telescopic adjustment of the telescopic rod 13, the cutting knife 12 continues to move downward and contact the plastic film 4 on the cutting plate 5 to cut it off. Then, the electric push plate 8 is moved up to drive the cutting knife 12 and the pressing plate 15 to move away from the positioning plate 6 and the cutting plate 5. The cut plastic film 4 will automatically fall on the receiving table 2 and remain between the baffle plate 11 and the cutting machine 1, effectively achieving the effect of automatically positioning the plastic film 4 before cutting it, and avoiding displacement and misalignment during cutting.

[0024] The second implementation method:

[0025] Figure 1 and Figure 3-4 It is shown that sliders are fixedly connected at both ends of the pressing plate 15, and the sliders are engaged with the second slide groove 14. The pressing plate 15 is made of solid iron material. The telescopic rod 13 is composed of a short ring arranged outside a long cylinder. A spring 17 is fixedly connected to the top end of the short ring, and the bottom end of the spring 17 is fixedly connected to the long cylinder. The distance between the cutting knife 12 and the cutting plate 5 is equal to the length of the short ring. A second slide groove 14 is drilled on the top of the connecting plate 16, and the discharge shaft 3 is engaged with the second slide groove 14.

[0026] After the plastic film 4 is cut by the cutting knife 12, the electric push plate 8 drives the telescopic rod 13 and the cutting knife 12 to move upward, and the pressing plate 15 moves away from the positioning plate 6 through the movement of the electric push plate 8, and the cutting is carried out in sequence.

[0027] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
