Description

Technical Field

[0001] The invention relates to the field of synthetic leather processing, in particular to a production and processing device for wear-resistant polyurethane synthetic leather. Background Art

[0002] Existing synthetic leather needs to be dry-kneaded by a dry-kneading machine to soften the synthetic leather and increase the comfort of the synthetic leather. After the synthetic leather is dry-kneaded by the dry-kneading machine, the dry-kneading action of the dry-kneading machine will cause the synthetic leather to be twisted into a ball. Therefore, workers are required to unfold the twisted synthetic leather and then wind it up with a winding roller. In the process of workers unfolding the synthetic leather, in order to prevent the synthetic leather from being contaminated by the ground, a cloth is usually laid on the ground. However, the synthetic leather will sway in the process of workers unfolding the synthetic leather, and the width of the cloth is limited, which causes the synthetic leather to constantly rub against the ground, thereby causing the synthetic leather to be contaminated. Summary of the invention

[0003] In order to overcome the disadvantage that the synthetic leather is swayed when workers unfold it, which leads to continuous friction between the synthetic leather and the ground, thus causing the synthetic leather to be contaminated, the present invention provides a wear-resistant polyurethane synthetic leather production and processing equipment.

[0004] The technical scheme is: a wear-resistant polyurethane synthetic leather production and processing equipment, including a support frame, a dry kneading machine and a fixed tube; the dry kneading machine is installed at the rear of the support frame; the fixed tube is fixedly connected to the support frame; it also includes a moving ring, a straightening ring and a fixed ring; a track is fixedly connected to the fixed tube, and an electric slider is arranged on the track; the electric slider is jointly connected to a moving ring for assisting the movement of synthetic leather, and the moving ring is fixedly connected to a silicone rod in a shrinking shape; two electric guide rails are fixedly connected to the support frame; the slider on the electric guide rail is rotatably connected to a straightening ring for straightening the synthetic leather twisted into a ball through a fixed plate; the straightening ring is installed with a motor, and a gear is fixedly connected to the power end of the motor; a gear meshing with the gear is arranged on the straightening ring; an extrusion airbag is installed on the straightening ring; the support frame is fixedly connected to the fixed ring, and a fixed airbag is arranged on the fixed ring.

[0005] Furthermore, a rubber ball head is arranged at the front end of the silicone rod on the moving ring.

[0006] Furthermore, elastic films are fixedly connected to the front and rear sides of the electric slider, and the films are used to completely cover the track.

[0007] Furthermore, the extrusion airbag on the squaring ring and the fixing airbag on the fixing ring are both arranged in four parts.

[0008] Furthermore, it also includes a visual sensor; the visual sensor is installed on the straightening ring.

[0009] Furthermore, it also includes a smoothing system, which includes a smoothing airbag, a mounting frame, a slide rail, a push rod and a top block; a smoothing airbag is arranged at the front of the fixed ring; a mounting frame is fixedly connected to the support frame, and the mounting frame is located between the straightening ring and the fixed ring; two slide rails are fixedly connected to the upper side of the interior of the mounting frame; two figure-eight slide rails are fixedly connected to the lower side of the interior of the mounting frame; a push rod is fixedly connected to the electric slider on each slide rail; and a top block for smoothing the synthetic leather is fixedly connected to the telescopic end of each push rod.

[0010] Furthermore, it also includes spherical blocks; each top block is rotatably connected to a plurality of spherical blocks on a side in contact with the synthetic leather.

[0014] The beneficial effects of the present invention are as follows: the present invention realizes controlling the rotation of the motor on the straightening ring by the visual sensor on the straightening ring, and then driving the straightening ring to rotate by the gear on the motor, thereby straightening the synthetic leather that is twisted into a ball, and then winding the synthetic leather by the winding roller, thereby replacing manual labor, thereby saving manpower, reducing labor costs, and improving work efficiency;

[0015] After the push rod limits the contact between the top block and the synthetic leather, the push rod stops moving, and the synthetic leather is limited by the smoothing airbag, and then the electric slider on the slide rail drives the push rod to move along the figure eight slide rail, so that the synthetic leather between the straightening ring and the fixing ring is slightly unfolded, which is convenient for the subsequent unfolding process of the synthetic leather, thereby saving time and improving work efficiency;

[0016] Workers place the front of the synthetic leather between the two pressing wheels on the arc frame. The pressing wheels are driven by the telescopic rods to move toward the middle, thereby limiting the position of the synthetic leather. When the synthetic leather moves forward, the synthetic leather can be unfolded again through the arc frame, thereby preventing the synthetic leather from rolling up in a wrinkled state and damaging the synthetic leather, thereby further improving work efficiency and reducing labor costs.

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention. Example 1

[0027] A wear-resistant polyurethane synthetic leather production and processing equipment, such as Figure 1-Figure 4 As shown, it includes a support frame 1, a dry kneading machine 2 and a fixed pipe 3; the dry kneading machine 2 is installed at the rear of the support frame 1; the fixed pipe 3 is fixedly connected to the support frame 1;

[0028] It also includes a moving ring 4, a straightening ring 5 and a fixed ring 6; a track 3001 is welded on the fixed tube 3, and an electric slider 300101 is arranged on the track 3001; the electric slider 300101 is connected to a moving ring 4, and a silicone rod in a shrinking shape is fixed to the front side of the moving ring 4; two electric guide rails 101 are bolted to the support frame 1 in a left-right symmetrical manner; the slider on the electric guide rail 101 is rotatably connected to the straightening ring 5 through a fixed plate; a motor 5001 is installed on the right side of the straightening ring 5, and a gear 5003 is welded to the power end of the motor 5001; a gear 5003 meshing with the gear 5003 is arranged on the straightening ring 5; an extrusion airbag 5002 is installed on the straightening ring 5; a fixing ring 6 is bolted to the front side of the support frame 1, and a fixed airbag 6001 is arranged on the fixing ring 6.

[0029] The front end of the silicone rod on the moving ring 4 is provided with a rubber ball head to prevent the silicone rod from damaging the synthetic leather during the moving process.

[0030] The front and rear sides of the electric slider 300101 are fixed with elastic films, which are used to completely cover the track 3001 to prevent the synthetic leather from falling onto the track 3001 and damaging the synthetic leather when the electric slider 300101 moves on the track 3001.

[0031] The squeezing airbag 5002 on the straightening ring 5 and the fixing airbag 6001 on the fixing ring 6 are both arranged in four parts, in order to avoid uneven inflation of the squeezing airbag 5002 and the fixing airbag 6001, thereby affecting the fixing effect.

[0032] The device also includes a visual sensor; a visual sensor is installed on the straightening ring 5; because the number of turns and directions of twisting of the synthetic leather are different, the number of turns of the straightening ring 5 is controlled by the visual sensor, and at the same time, the straightening ring 5 is controlled to rotate clockwise from the front to the back or counterclockwise from the front to the back, so as to straighten the twisted synthetic leather.

[0033] After the existing synthetic leather is dry-kneaded by the dry-kneading machine 2, the synthetic leather is rolled up by the winding roller. Due to the dry-kneading action of the dry-kneading machine 2, the synthetic leather will be twisted into a ball. Therefore, workers are required to unfold the twisted synthetic leather. In the process of the workers unfolding the synthetic leather, the synthetic leather will swing, which will cause the synthetic leather to constantly rub against the ground, resulting in damage to the synthetic leather. At the same time, manpower is wasted and labor costs are increased. The workers pass the synthetic leather through the straightening ring 5 and then through the fixed ring 6. In order to facilitate the workers to pass the synthetic leather through the straightening ring 5, the slider on the electric guide rail 101 is used to move the straightening ring 5 to the front side of the electric guide rail 101, thereby shortening the distance between the straightening ring 5 and the fixed ring 6. Before the workers pass the synthetic leather through the straightening ring 5 and the fixed ring 6, the extrusion airbag 5002 on the straightening ring 5 and the fixed airbag 5002 on the fixed ring 6 The airbags 6001 are all in an uninflated state. After the worker passes the front part of the synthetic leather through the fixing ring 6, the worker inflates the fixing airbag 6001 to fix the front part of the synthetic leather, and then inflates the squeezing airbag 5002 on the straightening ring 5 to fix the synthetic leather, and then fixes the two ends of the synthetic leather. At this time, the visual sensor on the straightening ring 5 controls the motor 5001 on the straightening ring 5 to rotate, and then the gear 5003 on the motor 5001 drives the straightening ring 5 to rotate, so as to straighten the synthetic leather that is twisted into a ball. At the same time, the straightening ring 5 is still slowly moving backward to the rear of the electric guide rail 101, so that the straightened and released synthetic leather is tightened and will not fall. The completely straightened synthetic leather is then rolled up by the winding roller, thereby replacing manual labor, thereby saving manpower, reducing labor costs, and improving work efficiency.

[0034] While the extrusion airbag 5002 on the straightening ring 5 fixes the synthetic leather, during the process of straightening the synthetic leather, the synthetic leather behind the straightening ring 5 is still being transported forward, so that a large amount of synthetic leather will be accumulated on the rear side of the straightening ring 5, causing the synthetic leather to contact the ground, thereby contaminating the synthetic leather and reducing the qualified rate of the product. Therefore, the workers pass the synthetic leather transported from the dry kneading machine 2 through the moving ring 4 and enter the fixed tube 3 for protection to prevent the synthetic leather from being contaminated. When the synthetic leather just leaves the dry kneading machine 2 and enters the fixed tube 3, due to lack of external force, the synthetic leather is accumulated at the rear of the fixed tube 3, which in turn causes the fixed tube 3 to be blocked, affecting the use of the fixed tube 3. Therefore, the electric slider 300101 on the track 3001 drives the moving ring 4 to move forward, so that the bristles on the moving ring 4 with a narrow mouth are used to support the synthetic leather at the rear of the fixed tube 3 and transport it forward. When the moving ring 4 moves backward, the moving ring 4 reciprocates through the moving ring 4, so that the synthetic leather is accumulated at the front of the fixed tube 3. Example 2

[0035] On the basis of Example 1, Figure 1 , Figure 5 and Figure 6As shown, a smoothing system is also included, which includes a smoothing airbag 102, a mounting frame 201, a slide rail 202, a push rod 203 and a top block 204; a smoothing airbag 102 is arranged at the front of the fixing ring 6; a mounting frame 201 is bolted to the support frame 1, and the mounting frame 201 is located between the straightening ring 5 and the fixing ring 6; two figure-eight slide rails 202 are bolted to the upper side of the mounting frame 201; two figure-eight slide rails 202 are bolted to the lower side of the mounting frame 201; the electric slider 300101 on each slide rail 202 is bolted to a push rod 203; and a top block 204 is bolted to the telescopic end of each push rod 203.

[0036] It also includes spherical blocks 205; a plurality of spherical blocks 205 in a rectangular array are rotatably connected on the side of each top block 204 that contacts the synthetic leather.

[0037] The spherical block 205 is made of rubber, which increases the friction between the spherical block 205 and the synthetic leather and protects the synthetic leather.

[0038] After the synthetic leather between the straightening ring 5 and the fixed ring 6 is straightened by the straightening ring 5, the push rod 203 drives the top block 204 to move toward the synthetic leather. When the top block 204 contacts the synthetic leather and limits the position, the push rod 203 stops moving. At this time, the push rod 203 is located at the rearmost end of the slide rail 202. At the same time, the fixed airbag 6001 on the fixed ring 6 is deflated, and the smoothing airbag 102 is inflated. The synthetic leather is limited by the smoothing airbag 102, and then the push rod 203 is driven by the electric slider 300101 on the slide rail 202 to move along the figure-eight slide rail 202, so that the synthetic leather between the straightening ring 5 and the fixed ring 6 is slightly unfolded, thereby facilitating the subsequent unfolding process of the synthetic leather, thereby saving time and improving work efficiency. Example 3

[0039] On the basis of Example 2, Figure 7 and Figure 8 As shown, it also includes an unfolding system, which includes an arc frame 301, a mounting block 302, a pressure wheel and a telescopic rod; two arc frames 301 that are symmetrical on the left and right are welded to the middle of the front side of the fixed ring 6, and each arc frame 301 is gradually bent from the back to the front; each arc frame 301 is provided with twelve slide grooves 30101 in a rectangular array; a telescopic rod is arranged in each slide groove 30101; a mounting block 302 is fixedly connected to the telescopic end of each telescopic rod; each mounting block 302 is rotatably connected to a pressure wheel through a fixed rod.

[0040] The edge of the pressing wheel is set to be a curved surface to prevent the pressing wheel from damaging the synthetic leather.

[0041] The worker places the front part of the synthetic leather between the two pressing wheels on the arc frame 301. The pressing wheels are driven by the telescopic rods to move toward the middle, thereby limiting the position of the synthetic leather. When the synthetic leather moves forward, the synthetic leather can be unfolded again through the arc frame 301, thereby preventing the synthetic leather from rolling up in a wrinkled state and damaging the synthetic leather, thereby further improving work efficiency and reducing labor costs.
