Description

Technical Field

[0001] The utility model belongs to the technical field of artificial leather production, and in particular relates to an eight-shaped cloth guiding support device for pre-processing and feeding of artificial leather production. Background Art

[0002] The utility model patent with application number 202111527733.7 discloses an automatic loading and unloading cloth opening machine for pre-processing of artificial leather production, in which the setting structure of the two figure-eight feeding rods has the following problems in actual production: the two feeding rods are symmetrical and horizontally arranged, and a fixed-height bracket is arranged at the lower part of the front end of the outer rod of the feeding rod. The figure-eight angle of the two feeding rods is adjusted by rotating the adjusting sleeve, and the connecting nut is tightened to tighten the adjusting sleeve after adjusting the figure-eight angle; the above structure has the following problems in the actual production process: since the feeding rod cannot be adjusted in the height direction, the height of the base cloth (after the bottom of the tube cloth is cut open) before being transported to the feeding rod is generally inconsistent with the height of the top of the front end of the feeding rod. When the inner sides of the left and right sides of the base cloth are respectively covered on the front ends of the left and right feeding rods, the edges and corners of the front end of the feeding rod will produce greater friction with the lower surface of the base cloth, which will seriously scratch the base cloth. Actual production experience shows that the feeding rod is tilted and set low at the front and high at the back. During the guidance and expansion process of the feeding rod, the base cloth is gradually transported upward to the feeding guide roller. The base cloth slides more smoothly along the guide rod and the expansion effect on the left and right sides is better. Utility Model Content

[0003] In order to solve the deficiencies in the prior art, the utility model provides an eight-shaped cloth guiding support device for artificial leather production pre-processing feeding, which can adjust the front end height and left and right directions of a feeding rod and improve the cloth guiding and spreading effects.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: an eight-shaped cloth guiding and supporting device for feeding artificial leather before production, comprising a left feeding rod and a right feeding rod symmetrically arranged on the left and right sides, the front end spacing of the left feeding rod and the right feeding rod being smaller than the rear end spacing, the front sides of the left feeding rod and the right feeding rod are connected by a transverse telescopic adjustment rod, a left height adjustment rod is hinged at the left end of the transverse telescopic adjustment rod, a right height adjustment rod is hinged at the right end of the transverse telescopic adjustment rod, the left height adjustment rod and the right height adjustment rod are symmetrically arranged on the left and right sides, the lower ends of the left height adjustment rod and the right height adjustment rod are hinged on the base, and the rear ends of the left feeding rod and the right feeding rod are respectively connected to the front side of the cloth opening box through a ball hinge assembly.

[0005] The lateral telescopic adjustment rod, the left height adjustment rod and the right height adjustment rod have the same structure, and all include an internal threaded sleeve, a first screw, a second screw, a first nut and a second nut. The external thread of the first screw is opposite to the external thread of the second screw.

The front end of the front hinge seat is provided with a tapered hole that is larger in the front and smaller in the rear. The rear end of the tapered hole is connected with the spherical groove.

[0008] The rear end of the inner rod of the left feeding rod passes through the tapered hole of the left ball hinge assembly and is fixedly connected to the left ball head, and the rear end of the inner rod of the right feeding rod passes through the tapered hole of the right ball hinge assembly and is fixedly connected to the right ball head.

[0009] The left height adjustment lever is set to be high on the left and low on the right and tilted, and the right height adjustment lever is set to be high on the right and low on the left and tilted.

[0013] 2) The length adjustment method of the lateral telescopic adjustment rod, the left height adjustment rod and the right height adjustment rod is as follows: first loosen the first nut and the second nut, and rotate the sleeve through the handle in turn. Since the spiral directions of the first screw and the second screw are opposite, when the sleeve is rotated in the forward or reverse direction, the distance between the first screw and the second screw can be increased or decreased. After adjusting the appropriate length, tighten the first nut and the second nut, and the length of the lateral telescopic adjustment rod, the left height adjustment rod and the right height adjustment rod is fixed.

[0014] 3) The left height adjustment rod is tilted to the left and the right, and the right height adjustment rod is tilted to the right and the left, so that it does not occupy the external space and does not affect the inner sides of the left and right sides of the base cloth sliding backward along the left feeding rod and the right feeding rod respectively.

[0015] 4) The ball hinge assembly adopts a split structure in which the front hinge seat and the rear hinge seat are connected by a flange bolt assembly, which is convenient for installing the ball head fixedly connected to the rear end of the inner rod. The opening of the tapered hole can increase the rotation angle of the ball head in the spherical groove and prevent the inner rod from touching the front hinge seat.

[0016] 5) The setting of the left and right cloth guide elbows makes it more convenient when starting to introduce the base cloth, and at the same time avoids the left and right feeding rods from scratching the base cloth with sharp edges at the front end.

[0017] To sum up, the utility model has a scientific principle and a compact structure. It does not change the telescopic structure of the existing left feeding rod and the right feeding rod. It only adopts a ball hinge assembly at the rear end and three telescopic adjustment rods are arranged at the front for linkage support, which improves the stability and smoothness of the cloth guiding and spreading operations. At the same time, the width and height can be adjusted according to the base cloths of different widths. BRIEF DESCRIPTION OF THE DRAWINGS
