Description

Edge shearing mechanism for glass fiber plaid stitch-bonded composite felt

Technical Field

The utility model relates to a weaving equipment field, especially a glass fiber check cloth stitch-bonding composite felt cut limit mechanism.

Background

In order to ensure the strength of the glass fiber plaid composite felt, the plaid composite felt needs to be seamed in the production process. And the plaid composite felt needs to be trimmed before edge sewing. However, the flexibility of the glass fiber is poor, and the produced checked cloth composite felt is loose, so that the cutting and trimming can not be carried out by using a cutter wheel. Therefore, the existing glass fiber checked cloth composite felt is trimmed by shearing. Then, the existing shearing and trimming device often has the situation that the fiber stepping speed is too high and the glass fiber slides out of the shearing mechanism in the fiber trimming process. Finally, the edge of the glass fiber checkered cloth composite felt is trimmed irregularly.

SUMMERY OF THE UTILITY MODEL

In view of the above, an object of the present invention is to provide an edge trimming mechanism for a glass fiber plaid stitch-bonded composite felt, which can effectively overcome the uneven trimming of the edge of the glass fiber plaid composite felt.

In order to achieve the above purpose, the technical scheme of the utility model is that:

an edge shearing mechanism of a glass fiber plaid stitch-bonded composite felt comprises a support, wherein conveying rollers are arranged on the support, first gears in transmission connection with the conveying rollers are symmetrically arranged on the outer side of the support, one of the first gears is in transmission connection with a driving motor, the first gears are meshed with second gears, first connecting rods are eccentrically hinged to the end surfaces of the second gears, one ends, far away from the second gears, of the first connecting rods are hinged to sliding rods, the sliding rods are slidably arranged in horizontally arranged guide grooves, one ends, far away from the first connecting rods, of the sliding rods are hinged to two second connecting rods which are arranged in a staggered mode, cutting edges are arranged on the two second connecting rods respectively, the two cutting edges are arranged in a staggered mode, and the second connecting rods are slidably arranged in; the two guide cylinders are of a V-shaped structure and are enlarged from one side close to the conveying roller to one side opening assembly far away from the conveying roller.

Further, the end of the second connecting rod is provided with a smooth cylindrical terminal, and the cylindrical terminal is in sliding fit with the inner side wall of the guide cylinder.

The working principle is as follows: in the production process, the conveying roller is driven by a driving end motor in transmission connection with the conveying roller to rotate, so that the glass fiber plaid stitch-bonded composite felt is driven to move forward at a constant speed. Meanwhile, the first gear coaxially connected with the conveying roller also rotates to drive the second gear to be driven, the second gear rotates to drive the first connecting rod eccentrically hinged with the second gear to move to and fro close to/away from the first gear, and the first connecting rod drives the second connecting rod to move together with the first connecting rod along with the movement of the first connecting rod. In the movement process of the second connecting rod, the second connecting rod is restrained by the guide cylinder to make a circulating opening and closing action, and then the cutting edge fixedly installed on the second connecting rod is driven to trim the edge of the glass fiber plaid stitch-bonded composite felt. It should be noted that, in the process of closing the two blades, the two blades move backwards together with the fabric under the action of the first connecting rod, so that the blades can keep moving synchronously with the glass fiber plaid stitch-bonded composite felt in the closing process, fibers at the edges of the glass fiber plaid stitch-bonded composite felt cannot slide out of the blades due to relative movement in the cutting process of the blades, and the cutting quality is ensured.

Has the advantages that: through the effect, the problem that the existing shearing mechanism is poor in effect of shearing the glass fiber plaid stitch-bonded composite felt and the condition of burrs easily occurs is effectively overcome.

Reference numerals: the device comprises a support 1, a conveying roller 2, a first gear 4, a driving motor 5, a second gear 6, a first connecting rod 7, a sliding rod 8, a guide groove 9, a second connecting rod 10, a blade 11, a guide cylinder 12 and a cylindrical terminal.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The edge shearing mechanism of the glass fiber plaid stitch-bonded composite felt comprises a support 1, wherein two conveying rollers 2 which are vertically distributed and mutually abutted are rotatably arranged in the support. And two first gears 3 are symmetrically arranged on the outer side surface of the bracket and are in transmission connection with the end part of one conveying roller. And a driving motor 4 is also connected to the end face of the first gear in a transmission manner. The first gear is driven to rotate through the rotation of the first driving motor. And a second gear 5 meshed with the first gear is also arranged on the bracket, and a first connecting rod 6 is eccentrically hinged on the end surface of the second gear. One end of the first connecting rod, which is far away from the second gear, is hinged with a sliding rod 7, and the surface of the sliding rod is smooth and horizontally arranged. And the slide bar is arranged in a guide groove 8 in a sliding fit manner. The slide bar can only horizontally slide in the guide groove through the restraint of the guide groove and the first connecting rod on the slide bar. Meanwhile, two second connecting rods 9 which are staggered with each other are hinged at one end of the sliding rod, which is far away from the first connecting rod. The two second links are respectively provided with a blade 10. Specifically, the two blades are also staggered with each other. Through opening and closing up and down, the edges of the glass fiber plaid stitch-bonded composite felt can be built by the two blades. And the two blades can be opened and closed according to a preset track. The two second connecting rods are inserted into the guide cylinder 11 in a sliding fit manner. Specifically, the guide cylinders corresponding to the two second connecting rods are arranged in a V-shaped structure. And the opening assemblies of the two guide cylinders are enlarged from one side close to the conveying roller to one side far away from the conveying roller.

As a further improvement of the above embodiment, the second link is more preferably slidable in the guide tube. The end of the second link is provided with a smooth cylindrical terminal 12. Specifically, the cylindrical terminal is in sliding fit with the inner wall of the guide cylinder.
