Technical Field

[0001] This utility model relates to the field of film cutting technology, and in particular to a pull-out longitudinal slitting mechanism. Background Technology

[0002] In the processing industry of roll materials such as film, paper, and nonwoven fabric, longitudinal slitting is a basic and critical process. Its function is to cut wide master roll materials into multiple narrow strips of material at high speed and with precision according to product specifications. The slitting mechanism is the core component for realizing this function, and its performance directly affects the slitting efficiency, material edge quality, and overall efficiency of the production line. In the existing technology, the cutting device of the slitting mechanism is mostly directly fixed on the equipment frame. When the equipment is stopped for loading and unloading, the protruding cutting device not only occupies space and affects operation, but also poses a safety hazard of scratching the operators. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, where the cutting devices of slitting mechanisms are mostly directly fixed to the equipment frame, posing a safety hazard of scratching operators. This invention provides a pull-out longitudinal slitting mechanism.

The pull-out mechanism includes a linear drive body, the outer surface of which is fixedly connected to a guide rail, and the outer surface of which is slidably connected to a slide plate. One end of the slide plate is rotatably connected to a threaded column, and the outer surface of the slide plate is fixedly connected to a cylinder. The output end of the cylinder is fixedly connected to a connecting plate, and the outer surface of the connecting plate is fixedly connected to a support column. The top of the support column is fixedly connected to a support plate, and two positioning holes are provided on one side of the support plate. A sliding groove is provided on the outer surface of the support plate, and a shrinking mechanism is slidably connected to the inner wall of the sliding groove. The shrinking mechanism includes a sliding block, and the outer surface of the sliding block is slidably connected to the inner wall of the sliding groove.

[0005] In a preferred embodiment, a support base is fixedly connected to one side of the sliding block, and a cutting mechanism is fixedly connected to the outer surface of the support base.

[0006] In a preferred embodiment, an extension plate is fixedly connected to one side of the support base, and a limiting groove is formed on the outer surface of the extension plate, the limiting groove extending into the interior of the support base.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention features a threaded post that is rotatably connected to the slide plate. This allows the slide plate to be pulled backward to the center of the linear drive body by rotating the threaded post, effectively pulling the cutting mechanism backward.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] like Figure 1-5As shown, this utility model provides a technical solution: a pull-out longitudinal slitting mechanism, including a device body 1, a slide rail 2 fixedly connected to one end of the device body 1, a pull-out mechanism 3 slidably connected to the outer surface of the slide rail 2, the pull-out mechanism 3 including a linear drive body 31, a guide rail 32 fixedly connected to the outer surface of the linear drive body 31, a slide plate 33 slidably connected to the outer surface of the guide rail 32, a threaded column 34 rotatably connected to one end of the slide plate 33, a cylinder 35 fixedly connected to the outer surface of the slide plate 33, a connecting plate 36 fixedly connected to the output end of the cylinder 35, a support column 37 fixedly connected to the outer surface of the connecting plate 36, a support plate 38 fixedly connected to the top of the support column 37, two positioning holes 39 opened on one side of the support plate 38, a sliding groove opened on the outer surface of the support plate 38, a shrinking mechanism 4 slidably connected to the inner wall of the sliding groove, the shrinking mechanism 4 including a sliding block 41. The outer surface of the sliding block 41 is slidably connected to the inner wall of the sliding groove. A support base 42 is fixedly connected to one side of the sliding block 41. A cutting mechanism 43 is fixedly connected to the outer surface of the support base 42. An extension plate 44 is fixedly connected to one side of the support base 42. A limiting groove 45 is opened on the outer surface of the extension plate 44. The limiting groove 45 extends into the interior of the support base 42. A spring 46 is fixedly connected to the inner wall of the limiting groove 45. A moving column 47 is fixedly connected to one end of the spring 46. Two limiting blocks 48 are fixedly connected to the outer surface of the moving column 47. The outer surfaces of the two limiting blocks 48 are slidably connected to the inner wall of the limiting groove 45. A T-shaped rotating rod 49 is rotatably connected inside the moving column 47. A rotating plate 410 is fixedly connected to one end of the T-shaped rotating rod 49. A fixed column 411 is fixedly connected to one end of the rotating plate 410. The outer surface of the fixed column 411 is adapted to the inner diameter of the two positioning holes 39.

[0025] In this embodiment, a threaded post 34 is rotatably connected to the slide plate 33, which makes it easy to pull the slide plate 33 backward to the middle of the linear drive body 31 by rotating the threaded post 34, that is, to pull the cutting mechanism 43 backward. When not in use, it can be driven backward without accidentally injuring the operator or affecting the loading and unloading of materials. The cylinder 35 is used to control the distance between the blade of the cutting mechanism 43 and the object being cut. One end of the threaded post 34 is supported in the threaded hole of the support block on the outer surface of the slide plate 33 and rotates to drive the slide plate 33.

[0026] By setting a support plate 38, a sliding groove, and a sliding block 41, the cutting mechanism 43 can move towards the connecting plate 36 under the support of the support base 42, allowing the cutting mechanism 43 to move back to the center, further reducing the chance of accidental injury to the operator. The two positioning holes 39 are used to connect with the fixed column 411. The upper positioning hole 39 is the positioning position after the cutting mechanism 43 moves outward, and the lower positioning position is the positioning position on one side of the support plate 38. The T-shaped rotating rod 49 can be locked at both ends of the moving column 47, allowing the rotating plate 410 and the fixed column 411 to rotate while pulling the spring 46 outward, thus facilitating the removal of the fixed column 411 from the positioning hole 39, eliminating the limitation on the movement of the cutting mechanism 43. The limiting block 48 moves in the limiting groove 45 and will not detach from the support base 42. The spring 46 can also lock the fixed column 411 in the positioning hole 39 so that it will not easily detach.

[0027] Working principle:

[0028] like Figure 1-5 As shown, when the equipment is not in use, the cutting mechanism 43 can be retracted to the middle. By rotating the threaded column 34, the sliding plate 33 can be moved on the guide rail 32 using the thread transmission principle. Then, the fixed column 411 can be removed from the positioning hole 39 at the upper end. Subsequently, the support base 42 can be pushed to make the sliding block 41 slide in the sliding groove of the support plate 38, thereby driving the cutting mechanism 43 to move towards the connecting plate 36.

[0029] Once the cutting mechanism 43 has moved to the desired position, the rotating plate 410 and the fixed column 411 can be rotated by rotating the T-shaped rotating rod 49 and pulled outward. During this process, the spring 46 is stretched first, and the limiting block 48 and the moving column 47 also move in the limiting groove 45. The spring 46 is in a compressed state, and then the fixed column 411 is inserted into the positioning hole 39 at the lower end. The spring 46 is released so that the fixed column 411 will not easily fall out of the positioning hole 39, thereby fixing the position of the cutting mechanism 43.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
