Description

Technical Field

[0001] The utility model belongs to the technical field of PVC calendered artificial leather production, and specifically relates to a novel tube cloth guide support. Background Art

[0002] PVC calendered artificial leather is made of PVC rubber and base fabric (also called bottom fabric) compounded. The artificial leather bottom fabric is mainly knitted tube cloth. During production, the tube cloth purchased on the market must first be coated with a 10cm wide strip of sizing by a sizing wheel roller in the middle of the sizing strip. A non-sizing area of ​​about 0.8cm wide is left in the middle of the sizing strip (the blank area is easy to cut). The 10cm wide sizing strip (commonly known as small sizing due to its narrow width) is dried by hot air, and the tube cloth is put on the cloth support and moves from front to back. The current sizing device is located on the front side of the cloth support, and the sizing strip is on the upper surface of the tube cloth. In this case, after the cloth cutting knife cuts the tube cloth, the tube cloth wraps around the distribution support on the distribution rack from the bottom, and the left small sizing edge is from the left distribution support The left distribution support is wrapped (hooked) by the inner side of the top, and the right small pulp edge is wrapped (hooked) by the right distribution support from the inner side of the top of the right distribution support. In this distribution method, because the cutting opening of the tube cloth is on the top, the left small pulp edge and the right small pulp edge are easy to slide off from the distribution supports on both sides. Therefore, the conveying speed cannot be too fast (if the speed is fast, the tension will be unstable during the unfolding of the cloth, and the cloth edge will slide off the distribution support in an instant); in addition, the existing cloth supports have the following disadvantages: 1) They cannot be adjusted in the width direction and are difficult to adapt to the cloth guiding operation of tube cloths of different widths; 2) The cloth supports are welded with steel, and welding will deform the overall structure of the cloth supports, thereby generating unnecessary tension on the tube cloth and affecting the quality of the tube cloth. Utility Model Content

[0003] The utility model is to solve the above technical problems and provides a novel tube cloth guide support with roller-coated pulp strips located on the lower surface of the tube cloth, adjustable width and stable and non-deformed overall structure.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a new type of tube cloth guide support, including an intermediate connecting tube, a left cloth support assembly and a right cloth support assembly. The left cloth support assembly and the right cloth support assembly have the same structure and are symmetrically arranged on the left and right. The left cloth support assembly includes a cloth guide circular tube, a reinforced square tube and a connecting rod. The length directions of the cloth guide circular tube and the reinforced square tube are both arranged along the front-to-back direction. The cloth guide circular tube is fixed on the left side of the reinforced square tube. The diameter of the cloth guide circular tube is smaller than the height of the reinforced square tube. There are several intermediate connecting tubes and connecting rods and the number is the same. A connecting plate is fixed on the left end of the connecting rod. The connecting plate is fixedly connected to the right side of the reinforced square tube by rivets. The right end of the connecting rod is inserted into the left port of the intermediate connecting tube. The intermediate connecting tube is threaded with a top screw for pressing the outer circle of the connecting rod.

[0005] The front end of the cloth guide tube is bent downward to the front side of the sizing wheel of the sizing device. The cloth guide tubes on the left and right sides are connected by a cross bar arranged along the left and right directions. A pressure roller is rotatably provided in the middle of the rear side of the cross bar, which is pressed against the front and rear sides of the sizing wheel of the sizing device.

[0006] The lower end of the left cloth guide circular tube is bent to the right to form a left front guide structure, the lower end of the right cloth guide circular tube is bent to the left to form a right front guide structure, the rear end of the left cloth guide circular tube is bent to the right to form a left rear guide structure, and the rear end of the right cloth guide circular tube is bent to the left to form a right rear guide structure.

[0007] By adopting the above technical scheme, the specific working process of the utility model is as follows: the tube cloth placed on the cloth placing machine is transported backward along the cloth chute under the traction of the cloth placing traction device, and after the tube cloth is opened, it moves upward along the front side of the cloth guide support and upward and backward along the cloth guide tube of the cloth guide support in sequence, and the lower side surface of the tube cloth passes between the pressure roller and the sizing wheel of the sizing device, and the sizing wheel of the sizing device rolls the slurry to the middle part of the lower surface of the tube cloth, and the tube cloth moves backward along the cloth guide support, and the lower surface of the tube cloth contacts the conveyor mesh belt on the cloth feeding rubber roller, and the conveyor mesh belt drives the tube cloth to move from front to back.

[0008] The utility model is placed on a plurality of cloth feeding rubber rollers through a conveying mesh belt, and a frame is provided with limiting rubber wheels located on the left and right sides of the cloth guide support and a positioning hook located at the rear end of the cloth guide support for preventing backward sliding.

[0009] The front end of the cloth guide support is bent downward and extends to the front side of the sizing device, so that the sizing wheel of the sizing device rolls the sizing liquid on the bottom surface of the tube cloth, so that the small slurry is located on the lower surface of the tube cloth.

[0010] The cloth guide tube on the cloth guide support plays the role of guiding the cloth tube, and the reinforced square tube is used to enhance the strength and stability of the cloth guide tube. The front ends of the two cloth guide tubes are bent downward at about 90 degrees, and a pressure roller crimped with the slurry wheel is installed on a cross bar between the bent parts. The left front guide structure and the right front guide structure serve to facilitate the cloth tube to be put on the cloth guide support; the left rear guide structure and the right rear guide structure serve to facilitate the cloth tube to leave the cloth guide support smoothly. An adjustable length rod is provided between the two reinforced square tubes to facilitate the cloth guiding of cloth tubes of different widths. The length of the rod is adjusted by the length of the connecting rod extending into the middle connecting tube, and is fixed in place by a top screw.

[0011] The connecting plate where the end of the connecting rod is fixed is fixedly connected to the reinforced square tube by rivets. The reinforced square tube is a stainless steel square tube with thickened walls. After straightening, the cloth guide tube is spot welded on its outer side. This manufacturing method can prevent the cloth guide support from being deformed, bent, and uneven due to too many welding points. If the cloth guide support causes a large deformation due to welding or improper material selection, the linearity of the left and right cloth guide tubes will be poor, and the tension of the cloth tube will be unstable when passing through the cloth guide support. The cloth tube will shrink and narrow due to the high tension, or even deviate, making the pulp strip not centered relative to the cloth guide support, thereby affecting the cutting straightness of the subsequent cloth cutting knife assembly.

[0012] To sum up, the utility model has a simple structure, and the sizing is applied on the lower surface of the tube cloth, which improves the cloth opening speed and plays a good cloth guiding role. The width is convenient to adjust to adapt to tube cloths of different widths. The overall structure has good stability and few welding points, and is not easy to deform, avoiding the tension generated during the tube cloth transportation process that affects the quality of the tube cloth.
