Description

Technical Field

[0001] The utility model relates to a cutting device, in particular to a cutting device for work uniform fabrics. Background Art

[0002] In the early stage of work uniform production, it is necessary to cut the whole piece of fabric into fabric pieces of different length specifications first. The cutting devices in the prior art convey the fabric by means of transmission rollers. After being conveyed to the cutting position, flying shears are used for cutting. Since the fabric is soft and thin, the pressing force of the transmission rollers is limited, and the fabric is prone to sliding during cutting, resulting in size deviation. Although some devices in the prior art have added pressing plates driven by hydraulic rods at both ends of the flying shears, the flying shears will pull the fabric during operation, and the edges and corners of the pressing plates are prone to scratching the fabric. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a cutting device for work uniform fabrics to solve the technical problems in the above background art.

[0004] The technical solution of the utility model is as follows:

[0005] A cutting device for work uniform fabrics, the cutting device is equipped with a fabric cutting limiter, and the fabric cutting limiter includes two pneumatic boxes arranged in parallel and a pressure control component; the pneumatic boxes are made of metal, integrally in a flat long strip shape, with an opening at the bottom, and the opening is sealed by a highly elastic skin; each pneumatic box has an air pipe joint, and the air pipe joint is connected to the pressure control component through a pressure balance pipe.

[0006] Further, a tee joint is installed on the pressure balance pipe and is respectively connected to the air pipe joints of the two pressing boxes through the tee joint.

[0007] Further, it further includes an inverted T-shaped mounting rack. Convex fixing plates are integrally welded on both side walls at the two ends of the pneumatic box. A row of screw holes are opened on the fixing plates, and the fixing plates are connected to the inverted T-shaped mounting rack through bolts. At least one row of screw holes is opened on the horizontal part at the bottom of the inverted T-shaped mounting rack.

[0008] Further, both sides at the bottom of the pneumatic box are arc-shaped, and the highly elastic skin is fixed by bonding to the side wall of the pneumatic box on the outer periphery, and the bonding position is higher than the arc top at the bottom of the pneumatic box.

[0009] Further, the pressure control component is composed of a compression cylinder and an electric push rod. The electric push rod is fixed to the rear end of the compression cylinder through a connecting frame, and its push rod is connected to drive the piston of the compression cylinder.

[0010] Further, the highly elastic skin is a TPR, SBS, TPE elastomer material or latex.

[0011] The advantages of the present utility model are as follows:

[0012] On the basis of the prior art, the present utility model adds a fabric cutting limiter. When installing the fabric cutting limiter, the pressing boxes are symmetrically installed on both sides of the flying shear of the cutting equipment. Before starting to cut the fabric, the pressure control component pressurizes and inflates the starting box, and the highly elastic skin generates an expansion deformation, evenly pressing on the fabric at both ends of the flying shear. Since it is a surface contact, the friction force is large, which can ensure that the fabric will not slide during the cutting process, guarantee the accuracy of cutting, and the tight pressing of the highly elastic skin on the fabric will not damage the fabric.

[0016] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] As Figure 1-2 shown:

[0018] A work uniform fabric cutting equipment, the cutting equipment is equipped with a fabric cutting limiter (the rest of the cutting equipment adopts the prior art, and the present utility model is mainly an improvement on the basis of the existing equipment). The fabric cutting limiter includes two pneumatic boxes 1 arranged in parallel and a pressure control component; the pneumatic box 1 is made of metal to ensure its rigidity, and the whole is in a flat strip shape, with an opening at the bottom, which is sealed by a highly elastic skin 2 at the opening. The highly elastic skin 2 can adopt TPR, SBS, TPE elastomer materials or latex to ensure that it can easily deform and expand under pressure and can immediately return to its original state after the pressure disappears.

[0019] Each pneumatic box 1 is provided with an air pipe joint 11. The air pipe joint 11 is connected to the pressure control component through a pressure balance pipe 3. The air pressure change inside the pneumatic box 1 is adjusted through the pressure control component. Since the pressure boxes act synchronously, a tee 31 can be installed on the pressure balance pipe 3 and connected to the air pipe joints 11 of the two pressing boxes respectively.

[0020] When installing the fabric cutting limiter, the pressing boxes are symmetrically installed on both sides of the flying shear of the cutting equipment, as close to the flying shear as possible, but without interfering with the operation of the flying shear. The high-elastic skin 2 is as close as possible to the workbench of the cutting equipment, but does not block the normal transmission of the fabric. For the convenience of installation, convex fixing plates 12 can be integrally welded on both side walls at the two ends of the pneumatic box 1. A row of screw holes is opened on the fixing plate 12. The fixing plate 12 is connected to the inverted T-shaped mounting bracket 4 through bolts. At least one row of screw holes is opened on the horizontal part at the bottom of the inverted T-shaped mounting bracket 4, and then it is fixed to both sides of the cutting equipment through bolts.

[0021] In order to reduce the wear of the corners of the pneumatic box 1 on the high-elastic skin 2, both sides of the bottom of the pneumatic box 1 are arc-shaped. The high-elastic skin 2 is fixed by bonding to the side wall of the pneumatic box 1 on the outer periphery, and the bonding position is higher than the top of the arc at the bottom of the pneumatic box 1.

[0022] In order to facilitate the integration of sensors for automated control, the pressure control component is composed of a compression cylinder 5 and an electric push rod 6. The electric push rod 6 is fixed to the rear end of the compression cylinder 5 through a connecting frame 7, and its push rod is connected to drive the piston of the compression cylinder 5. Motor drive is more conducive to automated collaborative control.

[0023] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and variations to these embodiments still fall within the protection scope of the present invention.
