Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to a fiber fabric edge pressing device. Background Technology

[0002] In the processing of fiber fabrics, the conveying process is a crucial link connecting various steps, and it usually requires specialized output equipment to complete the directional transfer of the fabric. These output devices are mostly composed of components such as conveyor belts and guide rollers. As the fabric moves continuously on them, the edges and sides will inevitably rub or collide with the contact parts of the equipment.

[0003] The reason why the edges are prone to curling is twofold. Firstly, the fiber structure of the fabric edges is relatively loose, and the tension they experience during conveying differs from that of the central fabric, making them prone to shape changes due to uneven force. Secondly, there may be slight protrusions or installation angle deviations in the equipment contact parts, which may cause the fabric edges to be "hooked" or "pushed" when passing through, resulting in the edges curling up and lifting.

[0004] Once the fabric edges curl up, subsequent processing is prone to errors. For example, in the cutting process, curling edges can cause inaccurate positioning of the fabric edges, resulting in deviations between the cut dimensions and design requirements. In the printing or dyeing process, the curled edges may not be able to fit flat against the processing table, causing problems such as pattern misalignment and uneven dyeing. This not only reduces the product qualification rate but may also increase the waste of raw materials. Therefore, we propose a fiber fabric edge pressing device to solve the above problems.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1-4 As shown, a fiber fabric edge pressing device is disclosed, including a U-shaped frame 1. Four guide rollers 2 are rotatably connected inside the U-shaped frame 1. Existing deep groove ball bearings are fixedly sleeved at both ends of the guide rollers 2. The outer ring of the deep groove ball bearing is fixedly connected to the inner wall of the U-shaped frame 1. The same fiber fabric body 3 is slidably connected between the four guide rollers 2. When the fiber fabric body 3 is slidably conveyed between them, the resistance encountered during fabric conveying is reduced.

[0023] An electric push rod 4 is fixedly connected inside the U-shaped frame 1. A U-shaped plate 5 is fixedly connected to the top of the output end of the electric push rod 4. The electric push rod 4 drives the U-shaped plate 5 and related components to rise and fall flexibly through its own extension and retraction, adjusting the contact state between the rubber scraper 11 and the bottom of the fiber fabric body 3. This ensures that the rubber scraper 11 can make close contact with the fabric for leveling when needed, and can also be flexibly lowered when no work is required or when the fabric is being replaced.

[0024] Four drive rollers 8 are rotatably connected inside the U-shaped plate 5. Existing deep groove ball bearings are fixedly sleeved at both ends of the drive rollers 8. The outer ring of the deep groove ball bearings is fixedly connected to the inner wall of the U-shaped plate 5. The four drive rollers 8 are paired up and respectively driven by rubber drive belts 9. The tension of the rubber drive belts 9 is adjusted by existing tensioning wheels. Multiple rubber scrapers 11 are evenly fixedly connected to the outer walls of the two rubber drive belts 9. The rubber material has a certain elasticity and can play a smoothing role when in contact with the fabric without scratching the fabric surface.

[0025] Two stepper motors 10 are fixedly connected to the outer wall of the U-shaped plate 5. Two round holes are opened on the outer wall of the U-shaped plate 5. The inner walls of the two round holes are rotatably connected to the outer walls of the output shafts of the two stepper motors 10 respectively. One end of the output shafts of the two stepper motors 10 is fixedly connected to one end of the two transmission rollers 8 respectively. A mounting plate 12 is fixedly connected inside the U-shaped frame 1.

[0026] The bottom of the U-shaped plate 5 is provided with a lifting guide assembly, which includes two vertical guide sleeves 7. The bottom of the U-shaped plate 5 is fixedly connected to the top of the two vertical guide sleeves 7. The inner walls of the two vertical guide sleeves 7 are slidably connected with vertical guide rods 6. The bottom of the two vertical guide rods 6 is fixedly connected to the inside of the U-shaped frame 1. When the U-shaped plate 5 is lifted and lowered by the electric push rod 4, the vertical guide sleeves 7 slide along the vertical guide rods 6, which can guide and limit the lifting and lowering movement of the U-shaped plate 5, effectively preventing the U-shaped plate 5 from deviating or shaking when it is lifted and lowered.

[0027] The bottom of the mounting plate 12 is provided with a pressing assembly, which includes a hand-tightening screw 13. The outer wall of the mounting plate 12 has a threaded hole, and the inner wall of the threaded hole is threadedly connected to the outer wall of the hand-tightening screw 13. A tapered roller bearing is fixedly fitted at the bottom of the hand-tightening screw 13. A horizontal plate 14 is fixedly connected to the outer ring of the tapered roller bearing. Two guide rods 15 are fixedly connected to the top of the horizontal plate 14. Two sliding holes are opened on the outer wall of the mounting plate 12. The inner walls of the two sliding holes are slidably connected to the outer walls of the two guide rods 15 respectively. The two ends of the horizontal plate 14 are fixedly connected to the same V-shaped pressing plate 16. The tapered roller bearing ensures that the horizontal plate 14 only moves up and down and does not rotate with the hand-tightening screw 13. The two guide rods 15 slide along the sliding holes of the mounting plate 12 when the horizontal plate 14 is raised and lowered, playing a guiding role and preventing the horizontal plate 14 from deviating when it is raised and lowered.

[0028] Working principle: During use, the fiber fabric body 3 passes between four guide rollers 2 in the existing conveying process. The electric push rod 4 drives the U-shaped plate 5 to move upward. The upward movement of the U-shaped plate 5 is assisted by the lifting guide assembly to ensure that the U-shaped plate 5 moves vertically upward, driving multiple rubber scrapers 11 to move upward, so that their tops contact the bottom of the fiber fabric body 3. The multiple rubber scrapers 11 are divided into two groups by two rubber transmission belts 9. Two stepper motors 10 operate, and the two output shafts rotate in opposite directions, driving the two connected transmission rollers 8 to move upward. As the fabric body 3 rotates, the two transmission rollers 8 rotate, driving the two rubber transmission belts 9 to rotate. The rotation direction of the two rubber transmission belts 9 is outward, thereby driving the two sets of rubber scrapers 11 to move from the inside to the outside, flattening the bottom side of the fiber fabric body 3. When the top of the fiber fabric body 3 moves, the hand-tightening screw 13 is rotated through the mounting plate 12, driving the horizontal plate 14 to move downward. The downward movement of the horizontal plate 14 causes the bottom of the V-shaped pressing plate 16 to contact the top of the fiber fabric body 3. The V-shaped structure flattens the raised parts on both sides of the fiber fabric body 3 outward.

[0029] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the electric push rod 4 and the stepper motor 10 to facilitate the control of the overall operation.
