Problems solved by technology

[0003] Since the plastic film is wound on the feeding roller for conveying and cutting, and the plastic film between the pulling roller above and the feeding roller needs to be in a tight state during cutting, so that the slitting knife can cut the plastic film. Cutting and slitting, if the plastic film on the conveying roller ends, the last piece of plastic film will lose the pull of the feeding pipe, resulting in uneven cutting of the last piece of plastic film by the slitting knife

Embodiment 1

[0026] For example figure 1 -example Figure 5 Shown:

[0027] The invention provides a film slitting machine, the structure of which includes a pulling roller 1, a slitting knife 2, a slitting frame 3, a feeding roller 4, and a body 5, the pulling roller 1 is connected with the body 5, and the The slitting knife 2 and the slitting frame 3 are an integrated structure, the slitting frame 3 is welded to the body 5, and the feeding roller 4 is engaged with the body 5; the feeding roller 4 includes a clamping block 41 , the guide frame 42, the inner frame 43, the extension surface 44, the clamping block 41 and the extension surface 44 are integral structures, the inner frame 43 is installed in the inner position of the guide frame 42, the extension surface 44 and the guide frame 42 hinge connections.

[0028] Wherein, the inner frame 43 includes a receiving plate a1, a protruding block a2, a guide rod a3, and an elastic bar a4, the protruding block a2 is in clearance fit with t...

Embodiment 2

[0034] For example Figure 6 -example Figure 8 Shown:

[0035] Wherein, the slitting knife 2 includes a cutter body c1, a linkage rod c2, a linkage rod c2, a rebound piece c3, a sleeve frame c4, and a solid ring c5. The cutter body c1 is embedded and connected with the linkage rod c2, and the linkage The rod c2 is engaged with the middle solid ring c5, and the rebound piece c3 is installed between the linkage rod c2 and the sleeve frame c4. Strong spring steel material, through the thrust of the film on the cutter body c1, the linkage rod c2 can drive the cutter body c1 to swing backward along the middle solid ring c5, and the linkage rod c2 can be pulled and reset by the rebound piece c3.

[0036]Wherein, the cutter body c1 includes a blade c11, a connecting rod c12, a blade face c13, and an elastic piece c14. The blade c11 is movably engaged with the blade face c13 through the connecting rod c12. Between the knife face c13, there are three connecting rods c12, which are ...

Abstract

The invention discloses a film slitting machine structurally comprising a pulling roller, a slitting knife, a slitting frame, a conveying roller and a machine body. The pulling roller is connected with the machine body, the slitting knife and the slitting frame are of an integrated structure, the slitting frame is welded to the machine body, the conveying roller is movably clamped with the machinebody, and a plastic film can be clamped and fixed through a clip fixing block on a clamping and fixing block. The clamping and fixing block on the conveying roller is pulled by the plastic film, so that the clamping and fixing block can drive an extending surface to be unfolded along a guide frame, and therefore, the extending surface can be matched with the pulling roller to pull the final plastic film, a cutter body is pushed by the plastic film, the cutter body can swing backwards along a middle fixing ring under the cooperation of a linkage rod, and the linkage rod can drive the cutter body to swing forwards to cut the plastic film through pulling of a springback piece to the linkage rod.

Description

technical field [0001] The invention relates to the field of slitting machines, in particular to a film slitting machine. Background technique [0002] The film slitting machine is mainly used to cut the whole plastic film into strips. It can cut the plastic film pulled by the pulling roller through the slitting knife through the adjustable slitting knife on the slitting frame, so that the plastic The film can be uniformly cut into strips of required width, which are widely used in the production of plastic film products. Based on the above description, the inventors found that the existing film slitting machine mainly has the following deficiencies, such as : [0003] Since the plastic film is wound on the feeding roller for conveying and cutting, and the plastic film between the pulling roller above and the feeding roller needs to be in a tight state during cutting, so that the slitting knife can cut the plastic film. When cutting and slitting, if the plastic film on the...
