Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, and particularly relates to a cloth pressing device of a cloth laying machine. Background Art

[0002] A cloth laying machine is a machine that stacks rolls of seamless fabrics layer by layer in alignment on a cutting table for cutting. A cloth laying machine often has a cloth storage and feeding device, a cloth pressing device, and a fixed cutting device. Among them, the design of the cloth pressing device is the most critical. For example, CN201410196916.9 discloses a cloth pressing and stabilizing mechanism, which is a cloth pressing device of an improved cloth laying machine. During the cloth laying process, as the cloth pressing device moves forward, the air between the fabrics is driven away and escapes randomly. The air flow drives the fabrics to drift, resulting in the cloth laying being distorted or overlapping. This phenomenon is more serious in fabrics with poor air permeability, such as fabrics with a relatively high density or surface coatings. The same problem also exists in high-speed cloth laying.

[0003] Therefore, there is an urgent need to redesign and improve the cloth pressing device of the cloth laying machine, and propose a brand-new cloth pressing device for the cloth laying machine that can prevent fabric drift and work stably. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a brand-new cloth pressing device for a cloth laying machine. By applying a specially designed pressing rod and roller design, the air flow rate is reduced, the middle fabric is fixed, and the front fabric is fixed in advance. During the cloth laying process, the fabric no longer drifts, the cloth laying is stretched and flat, and at the same time, the cloth laying and pressing are more stable, which has outstanding effects on fabrics with a relatively high density or surface coatings and rapid cloth laying.

[0005] The utility model provides a cloth pressing device for a cloth laying machine, which includes a first bracket, a second bracket, a roller, a roller frame, and a pressing rod; the roller is connected to the roller frame in a bearing manner; the pressing rod includes a first bending part, a straight part, and a second bending part, and both ends of the straight part are respectively connected to the first bending part and the second bending part; the roller frame is connected to the straight part in a bearing manner, and the roller frame rotates around the axis of the straight part; one section of the first bending part far from the straight part is connected to the first bracket, and one section of the second bending part far from the straight part is connected to the second bracket.

[0006] The pressing rod is in a "ji" shape. One end of the first bending part is connected to the straight part, and the other end is located in front of the side of the straight part; similarly, one end of the second bending part is connected to the straight part, and the other end is located in front of the other side of the straight part; the first bending part and the second bending part have a certain degree of bending.

[0007] Furthermore, the cross-section of the pressing rod is circular.

[0008] Further, the first bracket is provided with a first sliding groove, and the second bracket is provided with a second sliding groove. The widths of the first sliding groove and the second sliding groove are both equal to the cross-sectional diameter of the pressing rod.

[0009] Further, a first limiting member and a second limiting member are provided on the first bending portion. The first limiting member and the second limiting member are respectively arranged on both sides of the first bracket; a third limiting member and a fourth limiting member are provided on the second bending portion. The third limiting member and the fourth limiting member are respectively arranged on both sides of the second bracket.

[0010] Further, the shapes of the first sliding groove and the second sliding groove are both arc-shaped. The first bending portion slides in the first sliding groove, and the second bending portion slides in the second sliding groove.

[0011] Further, the surface of the roller has anti-slip ribs.

[0012] Further, a first cloth feeding roller and a second cloth feeding roller are further included. Both ends of the first cloth feeding roller are respectively fixed to the first bracket and the second bracket, and both ends of the second cloth feeding roller are respectively fixed to the first bracket and the second bracket.

[0013] Further, the height of the first cloth feeding roller is higher than that of the second cloth feeding roller.

[0014] Further, the height of the second cloth feeding roller is higher than the top of the first sliding groove or the second sliding groove.

[0015] Further, the materials of the roller and the pressing rod are both metal.

[0016] The beneficial technical effects of the present utility model are as follows:

[0017] 1. The design of the rolling and bending pressing rod is used to slow down the air flow rate. The roller compacts and fixes the middle cloth in advance, and the bending pressing rod compacts and fixes the two sides of the front cloth in advance, thereby preventing the cloth from drifting, avoiding the cloth from being distorted or overlapping, making the laid cloth stretch and flat. At the same time, the cloth laying and pressing are more stable, and it has a prominent effect on the cloth with a relatively dense weave or a surface coating and rapid cloth laying.

[0018] 2. The pressing rod slides in the arc-shaped sliding groove, and the pressing rod drives the roller, so as to automatically adapt to the change of the cloth height in multi-layer cloth laying, without machine calibration or manual adjustment.

[0019] 3. The roller is provided with anti-slip ribs, and the pressing rod is provided with limiting members to ensure that the roller and the pressing rod do not shift laterally, ensuring the stable progress of the cloth pressing work. Description of the Drawings

It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0026] As Figure 1 shown, a cloth pressing device of a cloth laying machine includes a first bracket 11, a second bracket 12, a pressing rod, a roller frame 31, a roller 32, a first cloth feeding roller 41 and a second cloth feeding roller 42; a first sliding groove 111 is formed on the first bracket 11, a second sliding groove 121 is formed on the second bracket 12, the pressing rod is composed of a first bending part 21, a straight part 22 and a second bending part 23, the first bending part 21 and the second bending part 23 bend towards the straight part 22, the cross-section of the pressing rod is circular, the first bending part 21 slides in the first sliding groove 111, the second bending part 23 slides in the second sliding groove 121, the straight part 22 is connected to the roller frame 31, the roller frame 31 is connected to the roller 32, and a first cloth feeding roller 41 and a second cloth feeding roller 42 are arranged between the first bracket 11 and the second bracket 12.

[0027] As Figure 2 shown, the roller frame 31 includes a first bearing 311 and a second bearing 312. The first bearing 311 is connected to the straight part 22, allowing the roller frame 31 and the roller 32 to rotate as a whole relative to the straight part 2. The second bearing 312 is connected to the roller 32, allowing the roller 32 to rotate relative to the roller frame; a plurality of slightly protruding anti-slip ribs 321 are formed on the surface of the roller 32.

[0028] AsFigure 3 As shown, a first limiting member 211 and a second limiting member 212 are sleeved on the first bending portion 21, and the first limiting member 211 and the second limiting member 212 are respectively arranged on both sides of the first bracket 11; a third limiting member 231 and a fourth limiting member 232 are sleeved on the second bending portion 23, and the third limiting member 231 and the fourth limiting member 232 are respectively arranged on both sides of the second bracket 12.

[0029] Combined with Figures 1-4 ( Figure 4 To avoid occlusion, the first bracket 11 is omitted), the working principle of the cloth pressing device:

[0030] First, the cloth 5 passes under the first cloth feeding roller 41 and then above the second cloth feeding roller 42 and is fed into the working platform at the bottom; then the cloth 5 contacts the front end of the pressing rod, that is, contacts the first bending portion 21 and the second bending portion 23, and first fixes the two side edges of the cloth 5 to prevent side shift;

[0031] There are pulleys at the bottoms of the first bracket 11 and the second bracket 12, which slide forward along the working platform, so that the roller 32 is pushed forward, the whole pressing rod is pushed forward, the roller 32 pushes and compacts the cloth in the middle of the cloth 5, and the first bending portion 21 and the second bending portion 23 fix the cloth in front in advance. At the same time, the space expands and the gas flow rate decreases, and the cloth no longer drifts, and the laid cloth is stretched and flat;

[0032] The roller frame 31 and the straight portion of the pressing rod are connected by bearings. Therefore, the roller frame 31 can always maintain a state where one end is lifted, so that while the whole pressing rod completely presses the cloth, the roller 32 can press the cloth and roll forward; specifically, the roller frame 31 and the pressing rod are made of a metal material with a relatively large density to increase its weight to ensure that when the pressing rod is towed by the first bracket 11 and the second bracket 12, the pressing rod still closely adheres to the cloth;

[0033] Anti-slip ribs 321 are provided on the roller 32 to prevent the roller 32 from slipping sideways. At the same time, limiting members are applied to ensure that the pressing rod does not slip sideways. Therefore, the cloth pressing device can stably press the cloth, and provides better effects for cloth with poor air permeability (such as cloth with a relatively dense weave or a surface coating) or high-speed cloth laying.

[0034] When the cloth pressing device moves forward to the top, the fixed cutting device located on one side of the workbench will cut and fix the cloth. Subsequently, the whole cloth pressing device retreats to the starting point to start a new round of cloth laying. As the stacking height of the cloth at the bottom increases, the first bending part 21 and the second bending part 23 move in the first sliding groove 111 and the second sliding groove 121 respectively, so that the height of the pressing rod is raised to just be able to press the new cloth. The sliding groove has a certain damping, and the pressing rod has a certain weight. Only the increase in the cloth height can cause the pressing rod to rise. As the stacking height of the bottom cloth increases, the height of the pressing rod increases, so the difficulty of sliding in the arc-shaped sliding groove also increases, and the frictional force is more difficult to resist gravity. Therefore, the pressing rod can exert a greater pressure on the lower cloth, which is more conducive to pressing the multi-layer cloth and discharging the air between the multi-layer cloth.

[0035] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as the protection scope of the present invention.
