Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing, in particular to a non-woven fabric feeding device. Background Art

[0002] Non-woven fabrics have no warp and weft, so they are very convenient to cut and sew. They are also light and easy to shape, making them popular among handicraft enthusiasts. They do not require spinning or weaving, but simply orient or arrange textile staple fibers or filaments at any time to form a fiber mesh structure, which is then reinforced by mechanical, thermal bonding or chemical methods. They are not interwoven or knitted together by yarns one by one, but the fibers are directly bonded together by physical methods. Therefore, non-woven fabrics have broken through traditional textile raw materials and have the characteristics of short process flow, fast production rate, high output, low cost, wide use and multiple sources of raw materials.

[0003] In the process of non-woven fabric processing, a feeding device is needed to feed the non-woven fabric. The Chinese utility model patent with the announcement number CN214059377U discloses a feeding device for non-woven fabric, including two brackets, a driving roller is connected between the two brackets, a support seat is connected to the outer wall of the bracket, a motor is connected to the outer wall of the support seat, the output end of the motor passes through the bracket and is fixedly connected to the driving roller, the top outer walls of the two brackets are both cut with grooves, the inner wall of the groove is connected with a positioning block, the outer wall of the positioning block is connected with a rotating shaft, an auxiliary roller is connected between the two rotating shafts, the bracket and the outer wall of the positioning block are cut with matching through holes, and the inner wall of the through hole is connected with a positioning rod. The utility model solves the problem that when the auxiliary roller is disassembled for maintenance and replacement, it is easy to increase the difficulty of disassembly because the center of gravity acts on the bolt at the other end after disassembling the bolt at one end, and the disassembly process is simple and quick, which is conducive to improving work efficiency.

[0004] However, during use of the utility model, the auxiliary roller and the driving roller need to press the non-woven fabric tightly before the non-woven fabric can be transported. However, the thickness of different types of non-woven fabrics are different, and the height of the auxiliary roller cannot be adjusted. This may cause the non-woven fabric to be excessively squeezed, affecting the quality of the non-woven fabric and failing to meet production needs. Therefore, a non-woven fabric feeding device is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a non-woven fabric feeding device, which has the advantage of being suitable for non-woven fabrics of different thicknesses. It solves the problem that the auxiliary roller and the driving roller need to press the non-woven fabric before the non-woven fabric can be conveyed, but the thickness of different types of non-woven fabrics are different, and the height of the auxiliary roller cannot be adjusted, which may cause the non-woven fabric to be excessively squeezed, affecting the quality of the non-woven fabric and failing to meet production needs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a non-woven fabric feeding device, comprising a workbench and a conveyor belt device fixedly installed on the top of the workbench, the front and back sides of the top of the workbench are fixedly connected with support boxes, and an elastic downward pressing structure is arranged between the two support boxes;

[0007] The elastic downward pressure structure includes a positioning guide rod fixedly connected to the inside of the support box, the outside of the positioning guide rod is slidably connected to a positioning sleeve, a compression spring is fixedly connected between the positioning sleeve and the inner wall of the support box, a downward pressure roller is arranged between the two support boxes, and the side of the positioning sleeve close to the downward pressure roller is fixedly connected to a connecting block extending to one side of the support box.

[0008] Furthermore, one end of the connecting block away from the positioning sleeve is fixedly connected to the positioning sleeve, the interior of the lower pressure roller is fixedly connected to a return spring, and one end of the return spring is fixedly connected to an elastic connecting rod extending into the interior of the positioning sleeve.

[0009] Furthermore, the connection between the positioning sleeve and the elastic connecting rod is a sliding connection, and movable grooves adapted to the connecting blocks are provided on opposite sides of the two supporting boxes.

[0010] Furthermore, a driving roller is rotatably connected between the two support boxes, and a driving motor for rotating the driving roller is fixedly installed on the front side of the support box.

[0011] Furthermore, support frames extending to the top of the conveyor belt device are fixedly installed on the front and back sides, and the top of the support frame is threadedly connected to a threaded rod extending into the interior thereof, and one end of the threaded rod close to the conveyor belt device is rotatably connected to a limiting plate, and the end of the threaded rod away from the limiting plate is fixedly connected to a rotating handle.

[0012] Furthermore, two support plates are fixedly connected to the side of the workbench top away from the conveyor belt device, a winding drum is arranged between the two support plates, and the front and back sides of the winding drum are fixedly connected to mounting rods extending to the side away from the two support plates.

[0013] Furthermore, the insides of the two support plates are each provided with a limiting groove adapted to the mounting rod, and the mounting rod is in a T-shape.

[0014] Compared with the prior art, the utility model provides a non-woven fabric feeding device, which has the following beneficial effects:

[0015] 1. The non-woven fabric feeding device can make the positioning sleeve slide on the surface of the positioning guide rod by arranging the positioning guide rod and the positioning sleeve, and can elastically move the positioning sleeve by arranging the clamping spring, and can lift and lower the lower pressure roller by arranging the connecting block. When the staff places the non-woven fabric between the lower pressure roller and the driving roller, the lower pressure roller can move upward due to the action of the clamping spring, and then automatically adapt to the thickness of the non-woven fabric, so as to facilitate the conveying of the non-woven fabric.

[0016] 2. The non-woven fabric feeding device can achieve the effect of feeding the non-woven fabric by setting a conveyor belt device, and at the same time, the non-woven fabric can be spread out, which is more convenient for the staff to process it. At the same time, the rotating handle is rotated to drive the threaded rod to rotate and move downward, and then move downward through the limit plate, which can prevent the non-woven fabric from shifting during the transmission process. It solves the problem that the auxiliary roller and the driving roller need to press the non-woven fabric before the non-woven fabric can be transported, but the thickness of different types of non-woven fabrics is different, and the height of the auxiliary roller cannot be adjusted, which may cause the non-woven fabric to be over-squeezed, affecting the quality of the non-woven fabric and failing to meet production needs.
