Description

Technical Field

[0001] The utility model relates to the field of cutting devices, in particular to a cutting device for producing pearl cotton. Background Art

[0002] EPE pearl cotton adopts polyethylene foam with non-cross-linked closed-cell structure. It is a new type of environmentally friendly packaging material. It is composed of low-density polyethylene grease that is physically foamed to produce countless independent bubbles. It overcomes the shortcomings of ordinary foam rubber such as fragility, deformation and poor recovery. Usually, the pearl cotton after molding is mostly continuous roll material. When needed, it can be cut into different shapes for packaging according to needs.

[0003] However, since most current EPE cutting devices cut a piece of material in batches, when cutting multiple layers of material, the cutting mechanism does not have a good positioning mechanism, resulting in a deviation in the shape of the EPE after cutting. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides an EPE production and cutting device, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: a pearl cotton production cutting device, comprising a cutting frame, a cutting mechanism is provided at one end of the cutting frame, a cutting mold is installed on the side end of the cutting frame away from the cutting mechanism, the cutting mold comprises two guide slides, positive and negative screw rods are connected between the two guide slides, an auxiliary positioning mechanism is arranged in an array on the upper surface of the guide slide, the outer end of the auxiliary positioning mechanism is located inside the guide slide and a limiting screw is provided, the auxiliary positioning mechanism comprises: a positioning pin, a limiting sleeve, and a spring, the lower end of the spring is located on the outside of the positioning pin and a pressing gasket is installed, the lower end of the limiting screw is installed with a pressing base, and the outer side of the limiting screw is located on the guide slide and an adjusting screw hole is opened.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-5 As shown, this embodiment provides a pearl cotton production cutting device, including a cutting frame 1, a cutting mechanism is provided at one end of the cutting frame 1, a cutting mold 7 is installed at one end of the cutting frame 1 away from the cutting mechanism, and the cutting mold 7 includes two guide slides 701, and a positive and negative threaded rod 702 is connected between the two guide slides 701. The guide slide 701 is engaged with the positive and negative threaded rod 702 and is movably connected. The anti-slip pad 705 is fixedly connected to the positive and negative threaded rod 702. The upper surface array of the guide slide 701 is provided with an auxiliary positioning mechanism 703, and the outer end of the auxiliary positioning mechanism 703 is located at the guide slide A limiting screw 704 is set inside the frame 701, and the auxiliary positioning mechanism 703 includes: a positioning pin 707, a limiting sleeve 708, and a spring 709. The limiting sleeve 708 is set through the guide slide 701. The lower end of the spring 709 is located on the outside of the positioning pin 707 and is equipped with a pressing gasket 710. The lower end of the limiting screw 704 is equipped with a pressing base 712. The outside of the limiting screw 704 is located on the guide slide 701 and is provided with an adjusting screw hole 711. The limiting screw 704 is engaged and movably connected with the adjusting screw hole 711. The spring 709 is fixedly connected to the pressing gasket 710 and the limiting sleeve 708.

[0024] like Figure 2-5As shown, in this embodiment, a slider 706 is installed at the outer end of the positive and negative screw rods 702, and a slide groove 8 is provided on the outer side of the slider 706 on the cutting frame 1. The guide slide 701 is slidably connected to the slide groove 8 through the slider 706. The cutting mechanism includes: a longitudinal guide frame 2, a transverse guide frame 3, and a vertical guide frame 5. One side of the vertical guide frame 5 is located between the transverse guide frame 3 and is connected with a drag chain 4. The longitudinal guide frame 2 is slidably connected to the cutting frame 1, and the vertical guide frame 5 is slidably connected to the transverse guide frame 3. A cutting knife 6 is installed in front of the vertical guide frame 5.

[0025] The working principle of the present invention is as follows: when processing is required, the pearl cotton sheet to be cut is placed on the upper surface of the cutting frame 1 as a whole, and according to the size of the cutting, the positive and negative screw rods 702 are controlled to apply a torque to adjust the distance between the two guide slides 701. Therefore, multiple groups of cutting dies 7 are arranged inside the slide 8 to facilitate the positioning of the pearl cotton sheet, and then the limiting screw 704 is used to apply a torque to control the limiting screw 704 to engage and rotate with the adjustment screw hole 711, so that the pressing base 712 is pressed as a whole. At both side sections of the pearl cotton sheet, the longitudinal guide frame 2 is driven to move as a whole on the outside of the cutting frame 1, and the vertical guide frame 5 moves horizontally on the horizontal guide frame 3, so that the cutting knife 6 cuts the pearl cotton sheet. When the number of layers of the pearl cotton sheet cut above is large, the positioning pin 707 is pulled upward as a whole, and the pressing gasket 710 compresses the spring 709 to deform. After the pulling force is released, the positioning pin 707 is lifted and inserted into the interior of the pearl cotton sheet as a whole, and the multi-layer pearl cotton can be limited to prevent the pearl cotton from being offset when the cutting knife 6 is cutting.
