Description

Technical Field

[0001] This utility model relates to the field of fabric turning machine technology, specifically an automatic pulling device for fabric turning machines. Background Technology

[0002] Fabric turning machines are key equipment in the textile, printing and dyeing, and finishing industries. They are mainly used to adjust the front and back of the fabric, eliminate wrinkles, and evenly unfold the fabric surface for subsequent cutting, printing, or quality inspection. Airflow fabric turning machines are devices that use high-speed airflow to drive the fabric to turn over. They are mainly used in the textile, printing and dyeing, and finishing industries to help the fabric unfold evenly, remove wrinkles, or adjust the direction of the fabric surface.

[0003] Currently available airflow-type fabric turning machines typically use an airflow generator to produce high-speed airflow. This airflow is guided to the fabric surface through pipes or nozzles to create negative or positive pressure, thereby generating suction or thrust to pull the fabric. However, the length of the turning cylinder on the airflow-type fabric turning machine is fixed. Therefore, when pulling longer fabrics, it is difficult for the airflow to completely suspend the fabric on the turning cylinder. At this time, the operator needs to frequently move the suspended part of the fabric backward to straighten it, exposing part of the turning cylinder until all the fabric is completely suspended on the turning cylinder. This operation is not only troublesome, but also increases the workload of the operator. Furthermore, when the operator is straightening the fabric, the front end of the turning cylinder may get stuck because there is no one to guide it. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic pulling device for a fabric turning machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic pulling device for a fabric turning machine includes a fabric turning machine body, wherein two symmetrical straightening mechanisms are provided at the fabric turning cylinder of the fabric turning machine body;

[0007] The straightening mechanism includes an L-shaped frame that slides on the outside of the turning cylinder of the turning machine body. An arc-shaped plate is slidably connected to one side of each of the two L-shaped frames facing each other. Two symmetrical control components are provided on the side of the turning machine body. The control components are connected to the arc-shaped plates at corresponding positions and control the movement of the arc-shaped plates.

[0008] Furthermore, the main body of the fabric turning machine has two symmetrical fixed blocks that can be detachably connected to both sides of its side. A support spring is fixedly connected between the arc plate and the L-shaped frame at the corresponding position. The control component includes a circular roller that rotates between the two fixed blocks at the corresponding position. A pull rope that passes through the L-shaped frame at the corresponding position and is fixedly connected to the arc plate at the corresponding position is wound and fixedly attached to the outer wall of the circular roller.

[0009] Furthermore, each of the two fixed blocks at a relative position has a fixed ring fixedly connected to one of its opposite sides, and a spring is provided between the fixed ring and the corresponding roller.

[0010] Furthermore, both ends of the outer wall of the arc-shaped plate are fixedly connected to limiting plates that slide through the L-shaped frame at the corresponding positions.

[0011] Furthermore, a rubber pad is fixedly connected to the inner wall of the arc-shaped plate.

[0012] Furthermore, one end of the L-shaped frame is fixedly connected to a slider, and the side of the fabric turning machine body is provided with two symmetrical screw rods that are screwed through and engaged with the sliders at corresponding positions. One end of the screw rod is rotatably connected to an mounting block via a bearing, and the mounting block is detachably connected to the fabric turning machine body.

[0013] Furthermore, a support plate is provided at the other end of the lead screw, and a motor is fixedly connected to the top side of the support plate. The output end of the motor passes through the support plate and is fixedly connected to the lead screw through a coupling.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the two curved plates move to the rear of the fabric turning tube, they come into contact with the fabric and push the fabric hanging at the front of the turning tube to the rear. This allows longer fabric to be placed over the outside of the turning tube without the need for staff to manually push the fabric to the rear. Instead, staff can guide the fabric at the front of the turning tube to prevent it from getting stuck. Attached Figure Description

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 4 In this embodiment of the present invention, an automatic pulling device for a fabric turning machine includes a fabric turning machine body 1. Two symmetrical straightening mechanisms 2 are provided at the fabric turning cylinder of the fabric turning machine body 1. The straightening mechanism 2 includes an L-shaped frame 21 that slides on the outside of the fabric turning cylinder of the fabric turning machine body 1. An arc plate 22 is slidably connected to one side of each of the two L-shaped frames 21. Two symmetrical control components are provided on the side of the fabric turning machine body 1. The control components are connected to the arc plate 22 at the corresponding position and control the movement of the arc plate 22.

[0023] Specifically, the fabric turning machine body 1 is existing technology. The details of how the fabric is pulled are omitted here. By connecting the control unit to the corresponding arc-shaped plate 22, when the arc-shaped plate 22 moves towards the air outlet of the fabric turning machine body 1, the two arc-shaped plates 22 move away from each other under the traction force of the control unit at their respective positions. When the two arc-shaped plates 22 move to a specific position on the fabric turning cylinder of the fabric turning machine body 1, the two L-shaped frames 21 respectively drive the arc-shaped plates 22 at their corresponding positions to move towards the discharge direction of the fabric turning machine body 1. At this time, the control unit releases the restriction on the arc-shaped plates 22, and the two arc-shaped plates 22 approach each other and move closer to the fabric on the fabric turning cylinder. The material comes into contact (at this time, there is a small gap between the arc plate 22 and the fabric turning cylinder to prevent the arc plate 22 from clamping the fabric on the outside of the fabric turning cylinder), and the movement of the two arc plates 22 can push the fabric near the air outlet towards the discharge port of the fabric turning machine body 1 (because the fabric is covered on the fabric turning cylinder and will have large wrinkles under the action of wind, the movement of the arc plate 22 can still push the fabric even without contacting the fabric turning cylinder), so that longer fabric can be covered on the outside of the fabric turning cylinder. The operator does not need to manually push the fabric to the back of the fabric turning cylinder. The operator can guide the fabric at the front end of the fabric turning cylinder to avoid the fabric getting stuck.

[0024] Example 1

[0025] like Figure 3 and Figure 4As shown, in this embodiment, two symmetrical fixing blocks 11 are detachably connected to both sides of the fabric turning machine body 1. A support spring 221 is fixedly connected between the arc plate 22 and the L-shaped frame 21 at the corresponding position. The control component includes a circular roller 23 that rotates between the two fixing blocks 11 at the corresponding position. A pull rope 24 that passes through the L-shaped frame 21 at the corresponding position and is fixedly connected to the arc plate 22 at the corresponding position is wound and fixedly fixed on the outer wall of the circular roller 23. A fixing ring is fixedly connected to the opposite side of the two fixing blocks 11 at the opposite position. A spring is provided between the fixing ring and the circular roller 23 at the corresponding position. Limiting plates 222 that slide through the L-shaped frame 21 at the corresponding position are fixedly connected to both ends of the outer wall of the arc plate 22. A rubber pad 223 is fixedly connected to the inner wall of the arc plate 22.

[0026] In this embodiment, when the L-shaped frame 21 moves towards the front end of the fabric turning tube, the pull rope 24 can be released and the circular roller 23 can be rotated, thereby causing the two springs at the corresponding positions to wind up. Under the action of the two springs, the pull rope 24 will generate a pulling force on the arc plate 22, causing the arc plate 22 to compress the support spring 221. At this time, the two arc plates 22 move away from each other, which can prevent the two arc plates 22 from pulling the fabric at the rear end of the fabric turning tube to the front end when moving towards the front end of the fabric turning tube. When the two L-shaped frames 21 move to a specific position, the two L-shaped frames 21 begin to move in opposite directions. At this time, the circular roller 23 begins to wind up the pull rope 24 under the action of the two springs. Due to the reverse movement of the L-shaped frames 21, the pulling force of the pull rope 24 on the arc plate 22 is reduced, thus the arc... The curved plate 22 returns to its original position under the action of the support spring 221 at the corresponding position. At this time, the two curved plates 22 contact the fabric on the turning tube, and the backward-moving curved plate 22 can push the fabric at the front end of the turning tube backward, avoiding the fabric hanging on the front end of the turning tube (as the fabric is released, more and more fabric will be on the turning tube. Although wrinkles will be produced, the fabric near the back of the turning tube is less affected by the wind force and the fabric is elastic. Therefore, the fabric hanging on the turning tube will move closer to the front end of the turning tube as the fabric is released. This will result in the fabric that is not hanging on the turning tube having no place to be hung. In the prior art, the fabric at the front end of the turning tube is pushed backward by the staff manually). Therefore, longer fabrics can be hung.

[0027] Example 2

[0028] like Figure 3As shown, in this embodiment, a slider 211 is fixedly connected to one end of the L-shaped frame 21. Two symmetrical screw rods 25 are provided on the side of the fabric turning machine body 1 and are screwed through the sliders 211 at the corresponding positions. One end of the screw rod 25 is rotatably connected to the mounting block 251 through the bearing. The mounting block 251 is detachably connected to the fabric turning machine body 1. A support plate 26 is provided at the other end of the screw rod 25. A motor 27 is fixedly connected to the top side of the support plate 26. The output end of the motor 27 passes through the support plate 26 and is fixedly connected to the screw rod 25 through the coupling.

[0029] In this embodiment, firstly, two symmetrical baffles (such as...) are fixed on the side of the fabric turning machine body 1 (the side closest to the fabric turning cylinder). Figure 2 As shown), the slider 211 is slidably connected to the baffle at the corresponding position via the connecting rod along the length of the screw 25. Then, the mounting block 251 is fixed to the body 1 of the fabric turning machine with bolts, and the support plate 26 is moved closer to the other end of the screw 25. The screw 25 is fixed to the motor 27 at the corresponding position with a coupling. By switching the forward and reverse rotation of the motor 27, the L-shaped frame 21 can move back and forth on the outside of the fabric turning cylinder, thereby pushing the fabric hanging at the front end of the fabric turning cylinder to the rear end.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
