Description

Technical Field

[0001] This utility model relates to the field of fabric feeding device technology, and more specifically, to a fabric feeding mechanism for double-sided leather production. Background Technology

[0002] Double-sided leather is a type of leather or leather alternative that is available on both sides and is widely used in placemats, tablecloths, bags, handbags, shoe leather, sporting goods, automotive interiors, and many other fields.

[0003] Currently, in the production of double-sided leather products, a feeding device is required to feed the rolled fabric. However, commonly used feeding devices are not convenient for positioning the central tube of rolled fabrics with different outer diameters, nor are they convenient for unloading rolled fabrics with different widths. For example, a double-sided leather production feeding device disclosed in publication number CN103183253A includes a feeding rack, guide rollers set on the feeding rack, and a central tube for winding the fabric. The guide rollers are composed of two parallel rollers, and the central tube is placed between the rollers. The rollers rotate with the central tube. Guide rollers extend from both ends of the central tube.

[0004] As can be seen from the above-mentioned disclosed solutions, when the central tube of the rolled fabric is installed on the feeding rack, it needs to come into contact with and rub against the inner wall of the clamp. However, the position of the clamp is fixed, and the friction intensity cannot be adjusted. Consequently, the tension of the fabric during the feeding process cannot be adjusted. Furthermore, when the rolled fabric with different outer diameters and different widths is installed, the height and length of the central tube are different, which may make it impossible to match with the clamp and narrow the scope of application. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a double-sided leather production feeding mechanism. This double-sided leather production feeding mechanism, through the setting of a vertical plate and clamping components, can adjust the height position to facilitate clamping both ends of the central tube of rolled fabric with different outer diameters. It can also prevent the central tube from moving horizontally after clamping, ensuring the feeding stability of the rolled fabric. Furthermore, through the setting of a crossbeam and adjusting seat, it can not only adjust the clamping strength of the friction block, thereby adjusting the tension, but also facilitate the positioning of rolled fabric with different widths, thus increasing the applicability.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A double-sided leather production fabric feeding mechanism includes a feeding mechanism body, a conveying roller rotatably connected to the surface of the feeding mechanism body, a crossbeam fixedly connected to the surface of the feeding mechanism body, a sliding groove on the surface of the crossbeam, an adjusting seat slidably connected to the surface of the crossbeam, a sliding hole at one end of the adjusting seat, a sliding rod movably sleeved on the surface of the adjusting seat, a first manual knob threadedly connected to the surface of the sliding rod, a moving component fixedly connected to the surface of the adjusting seat, and a clamping component slidably connected to the surface of the moving component. This double-sided leather production fabric feeding mechanism, through the vertical plate and clamping component, allows for height adjustment, facilitating the clamping of both ends of the central tubes of rolled fabrics with different outer diameters. It also prevents horizontal movement of the clamped central tubes, ensuring the stability of the rolled fabric feeding. Furthermore, the crossbeam and adjusting seat not only allow for adjustment of the clamping strength of the friction blocks, thereby adjusting the tension, but also facilitate the positioning of rolled fabrics with different widths, increasing its applicability.

[0008] Furthermore, the moving component includes a support frame, the bottom of which is fixedly connected to the surface of the adjusting seat. A vertical plate is fixedly connected to the surface of the support frame, and an adjusting groove is formed on the surface of the vertical plate. The adjusting groove allows the slider to slide up and down, thereby adjusting the height of the friction block, so that the friction block can contact the end face of the central tube of the rolled fabric with different heights.

[0009] Furthermore, the clamping assembly includes a friction disc, on the surface of which a friction block is fixedly mounted. The friction block is made of wear-resistant rubber and has a stepped limiting groove on its surface. The stepped limiting groove facilitates the limiting of center tubes with different outer diameters, preventing them from detaching from the friction block.

[0010] Furthermore, a connecting rod is fixedly connected to the surface of the friction disc, and a second manual knob is threadedly connected to the surface of the connecting rod. The end face of the second manual knob is movably connected to the surface of the vertical plate. The second manual knob can be manually tightened to position the slider.

[0011] Furthermore, a slider is fixedly sleeved on the surface of the connecting rod, the surface of the slider is movably connected to the inner wall of the adjusting groove, and a positioning part is fixedly connected to one end of the slider. The end face of the positioning part contacts the surface of the vertical plate, which can restrict the slider from moving horizontally.

[0012] Furthermore, an anti-detachment block is fixedly connected to one end of the slide rod, and the surface of the anti-detachment block is movably connected to the inner wall of the slide groove. The anti-detachment block can prevent the slide rod from moving upward.

[0013] Furthermore, a reinforcing plate is fixedly connected to the side of the vertical plate, and the bottom of the reinforcing plate is fixedly connected to the surface of the support frame. The reinforcing plate can increase the support strength and stability of the vertical plate.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] This solution, through the setting of vertical plates and clamping components, allows for height adjustment, facilitating the clamping of both ends of the central tubes of rolled fabrics with different outer diameters. It also prevents the central tubes from moving horizontally after clamping, ensuring the stability of the rolled fabric feeding.

[0016] This design, through the addition of a crossbeam and an adjusting seat, not only allows for adjustment of the clamping strength of the friction block, thereby regulating the tension, but also facilitates the positioning of rolls of fabric with different widths, thus increasing its applicability.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] Please see Figure 1-5A double-sided leather production fabric feeding mechanism includes a fabric feeding mechanism body 1. Two conveying rollers 11 are rotatably connected to the surface of the fabric feeding mechanism body 1, and each conveying roller 11 has a servo motor at one end, electrically connected to a control switch. This is prior art. The fabric feeding mechanism body 1 also includes guide rollers. A roll of fabric is placed on the surface of the two conveying rollers 11. A central tube is located at the center of the roll of fabric. The fabric passes downwards through the gap between the two conveying rollers 11, then contacts the guide rollers and exits from the side of the fabric feeding mechanism body 1. Its structure and working principle are well known to those skilled in the art. Two crossbeams 12 are fixedly connected to the surface of the fabric feeding mechanism body 1. The surface of each crossbeam 12 has a groove 13 with a T-shaped cross-section. An adjusting seat 2 is slidably connected to the surface of each crossbeam 12. One end of the adjusting seat 2 has a sliding hole 21. A sliding rod 22 is movably sleeved on the surface of the adjusting seat 2, and the surface of the sliding rod 22 is threaded. A first manual knob 24 is connected, which can be manually tightened. The adjustment position of the adjusting seat 2 is fixed by the squeezing force between the anti-detachment block 23 and the inner wall of the slide groove 13. A moving component 3 is fixedly connected to the surface of the adjusting seat 2. The moving component 3 includes a support frame 31. The bottom of the support frame 31 is fixedly connected to the surface of the adjusting seat 2. A vertical plate 32 is fixedly connected to the surface of the support frame 31. An adjustment groove 33 is opened on the surface of the vertical plate 32. The adjustment groove 33 allows the slider 45 to slide up and down, thereby adjusting the height of the friction block 42. This facilitates the contact between the friction block 42 and the end face of the central tube of the rolled fabric with different heights. A clamping component 4 is slidably connected to the surface of the moving component 3. The clamping component 4 includes a friction disc 41. A friction block 42 is fixedly installed on the surface of the friction disc 41. The friction block 42 is made of wear-resistant rubber. The surface of the friction block 42 is provided with a stepped limiting groove 43. The stepped limiting groove 43 facilitates the limiting of central tubes with different outer diameters and prevents them from detaching from the friction block 42.

[0026] A connecting rod 44 is fixedly connected to the surface of the friction disc 41. A second manual knob 47 is threadedly connected to the surface of the connecting rod 44. The end face of the second manual knob 47 is movably connected to the surface of the vertical plate 32. The second manual knob 47 can be manually tightened to position the slider 45. The slider 45 is fixedly sleeved on the surface of the connecting rod 44. The surface of the slider 45 is movably connected to the inner wall of the adjustment groove 33. A positioning part 46 is fixedly connected to one end of the slider 45. The end face of the positioning part 46 contacts the surface of the vertical plate 32, which can restrict the horizontal movement of the slider 45.

[0027] One end of the slide bar 22 is fixedly connected to an anti-detachment block 23. The surface of the anti-detachment block 23 is movably connected to the inner wall of the slide groove 13. The anti-detachment block 23 can prevent the slide bar 22 from moving upward. The side of the vertical plate 32 is fixedly connected to a reinforcing plate 34. The bottom of the reinforcing plate 34 is fixedly connected to the surface of the support frame 31. The reinforcing plate 34 can increase the support strength and stability of the vertical plate 32.

[0028] When using this double-sided leather production feeding mechanism, the rolled fabric is first placed on the surface of the two conveyor rollers 11. Then, the adjusting seat 2 is moved so that the two vertical plates 32 at both ends of the rolled fabric are close to the ends of the central tube of the rolled fabric. Then, the height of the friction disc 41 is adjusted according to the height of the central tube. After the height of the friction disc 41 is adjusted, the vertical plate 32 is moved horizontally so that the end face of the central tube is fitted into the limiting groove 43. Then, the second manual knob 47 is manually tightened clockwise to fix the position of the friction block 42. First, the first manual knob 24 on one side of the adjusting seat 2 is manually tightened clockwise to adjust the position of the friction block 42. The side adjustment seat 2 is positioned, thereby positioning one end of the central tube of the rolled fabric. Then, one end of the fabric is pulled out and passes through the main body 1 of the fabric feeding mechanism. Then, the servo motor is started, causing the conveyor roller 11 to rotate and drive the rolled fabric to rotate. Then, the other side adjustment seat 2, which is not fixed, is moved, causing the vertical plate 32 connected to the adjustment seat 2 to move. This causes the friction block 42 to press one end of the central tube to adjust the friction intensity and adjust the tension when feeding the fabric. After the tension is appropriate, the first manual knob 24 is manually tightened clockwise to fix the moving position of the adjustment seat 2. Then, the fabric feeding operation can be carried out.

[0029] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
