Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a bidirectional adjustable correction device. Background Technology

[0002] Leather is an indispensable category of consumer goods, widely used in clothing, footwear, home furnishings, automobiles, public services, and many other fields. Among leather products, cowhide products made from genuine cowhide are popular with consumers due to their superior performance and high-end feel, resulting in a large consumption volume.

[0003] The production of artificial leather involves the manufacture of cowhide base fabric. This cowhide base fabric is formed by wet-laying cowhide fibers into a web and then hydroentangling it.

[0004] Typically, a hydroentangling device is used to process the cowhide base fabric. In this technology, the hydroentangling device injects high-pressure water into the hydroentangling head, causing the hydroentangling head to generate hydroentanglements that spray and intertwine the multi-layer fiber web of nonwoven fabric, thereby giving the fiber web a certain strength.

[0005] The hydroentangling device, including a clamping feeding device and a flat mesh device, guides and conveys the cowhide base fabric. The flat mesh device includes several parallel tension rollers, on which tensioned mesh curtains are mounted. During operation, the mesh curtains may deviate from their designated path. The corrective mechanism used is a mechanical mechanism requiring manual operation. This type of corrective mechanism suffers from drawbacks such as complex structure, difficult maintenance, high failure rate, and high labor costs. With the rapid development of hydroentangling, the working speed of the mesh curtains is increasing, and manual correction is no longer sufficient to meet production needs. Therefore, a new type of corrective mechanism has been developed, mainly comprising a power source, a corrective frame, and a transmission mechanism located between the power source and the corrective frame to drive the left and right movement of the corrective frame. Because the corrective frame moves left and right at a very high frequency during normal operation, the corrective mechanism needs to have high sensitivity and accuracy. Therefore, existing corrective mechanisms typically use ball screws as the transmission mechanism. However, ball screws are prone to wear during high-frequency forward and reverse operation, requiring regular maintenance, which is costly. Utility Model Content

[0006] The purpose of this invention is to overcome the defects in the existing technology and provide a bidirectional adjustable correction device.

[0007] To achieve the above objectives, the technical solution of this utility model is to design a bidirectional adjustable correction device, including a frame. The frame is provided with a first roller, a second roller, a third roller, and a fourth roller. The first roller, the second roller, the third roller, and the fourth roller are arranged in parallel on the frame. Tensed net curtains are provided on the first roller, the second roller, the third roller, and the fourth roller. A correction roller is also provided on the frame between the second roller and the third roller. The two ends of the correction roller are respectively rotatably mounted on an adjustment mechanism, which is installed on the frame.

[0008] In a further preferred embodiment, the adjusting mechanism includes a support fixedly mounted on a frame. A constant-pressure air spring and a regulating-pressure air spring are mounted at both ends of the support. A swing seat is mounted in the middle of the support. One end of the constant-pressure air spring is mounted on one side of the support, and the other end is fixedly connected to the side of the swing seat adjacent to it. One end of the regulating-pressure air spring is mounted on the other side of the support, and the other end is fixedly connected to the side of the swing seat adjacent to it. A bearing seat is mounted on each swing seat, and both ends of the correction roller are respectively mounted on the bearing seats.

[0009] A further preferred technical solution also includes a compressed air source, wherein a constant pressure air spring is connected to the compressed air source through a pipe with a constant pressure reducing valve, and a pressure regulating air spring is connected to the compressed air source through a pipe with a pressure regulating reducing valve.

[0010] In a further preferred embodiment, the first roller is fixedly mounted on the frame, and the third roller is also fixedly mounted on the frame.

[0011] In a further preferred embodiment, the second roller is movably mounted on the frame and can be moved by a manual tensioning mechanism.

[0012] In a further preferred embodiment, the fourth roller is movably mounted on the frame and can be moved by an automatic tensioning mechanism.

[0013] The advantages and beneficial effects of this utility model are as follows: By utilizing the air pressure difference between a constant-pressure air spring and a variable-pressure air spring, and adjusting the air pressure of the variable-pressure air spring to deflect the correction roller, the misaligned screen curtain can be automatically corrected. This overcomes the technical defects of existing mechanical correction devices, which are prone to wear during high-frequency forward and reverse operation, require regular maintenance, and have high labor and maintenance costs. It achieves a simple, stable structure with high sensitivity and accuracy. This utility model is rationally designed, simple in structure, and low in manufacturing cost. It can achieve accurate and stable automatic correction, effectively reduce downtime for maintenance, ensure normal equipment operation, greatly save labor costs, and is easy to promote and apply.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figure 1-3 As shown, a bidirectional adjustable correction device includes a frame 1. The frame 1 is provided with a first roller 2, a second roller 3, a third roller 6, and a fourth roller 7. The first roller 2, the second roller 3, the third roller 6, and the fourth roller 7 are arranged in parallel on the frame 1. Tensed net curtains are provided on the first roller 2, the second roller 3, the third roller 6, and the fourth roller 7. In some embodiments, the first roller 2 is fixedly arranged on the frame 1, and the third roller 6 is also fixedly arranged on the frame 1.

[0020] The second roller 3 is movably mounted on the frame 1 and can be moved by a manual tensioning mechanism to tension the mesh curtain. The manual tensioning mechanism is a device that uses human power to adjust the mechanical structure to apply tension to the transmission components (belt, chain, or mesh curtain).

[0021] Spiral tensioning mechanism: The rotating screw pushes the nut slide, which drives the longitudinal displacement of the second tensioning roller 3, directly changing the tightness of the mesh curtain.

[0022] Worm gear tensioning mechanism: Rotating the handwheel drives the worm gear system to push the nut slide, which in turn causes the second tensioning roller 3 to move longitudinally, directly changing the tension of the mesh curtain.

[0023] The fourth roller 7 is movably mounted on the frame 1 and can be moved by the automatic tensioning mechanism to achieve tensioning of the net curtain. It is a device that automatically maintains constant tension of transmission components (belt, chain or net curtain) through built-in adjustment elements (such as spring, hydraulic or motor system), and can compensate for slack or deformation in real time without manual intervention.

[0024] The hydraulic automatic tensioning mechanism uses a hydraulic system that senses tension changes through a pressure sensor and adjusts the piston displacement to control the position of the fourth roller.

[0025] The electric automatic tensioning mechanism uses a motor-driven screw or gear mechanism, combined with a tension sensor to achieve closed-loop control, supports remote programming adjustment, and controls the position of the fourth roller 7.

[0026] A correction roller 4 is also provided on the frame 1 between the second roller 3 and the third roller 6. The two ends of the correction roller 4 are respectively rotatably mounted on the adjustment mechanism 5, which is installed on the frame 1.

[0027] The adjusting mechanism 5 includes a support 51, which is fixedly mounted on the frame 1. A constant-pressure air spring 55 and a regulating air spring 52 are mounted at both ends of the support. A swing seat 53 is mounted in the middle of the support 51. One end of the constant-pressure air spring 55 is located on one side of the support 51, and the other end is fixedly connected to the side of the swing seat 53 adjacent to it. One end of the regulating air spring 52 is located on the other side of the support 51, and the other end is fixedly connected to the side of the swing seat 53 adjacent to it. A bearing seat 54 is mounted on each swing seat 53, and both ends of the straightening roller 4 are respectively mounted on the bearing seat 54. By utilizing the air pressure difference between the constant pressure air spring 55 and the adjustable pressure air spring 52, the air pressure of the adjustable pressure air spring 52 is adjusted, causing the swing seat 53 to deflect and drive the correction roller 4 to deflect, thereby automatically correcting the misaligned screen curtain. This overcomes the technical defects of existing mechanical correction devices, which are prone to wear during high-frequency forward and reverse operation, require regular maintenance, have high labor costs, and have high maintenance expenses.

[0028] In one embodiment, a compressed air source is also included. The constant pressure air spring 55 is connected to the compressed air source through a pipe equipped with a constant pressure reducing valve, and the adjustable pressure air spring 52 is connected to the compressed air source through a pipe equipped with an adjustable pressure reducing valve. Both the constant pressure reducing valve and the adjustable pressure reducing valve are equipped with air pressure indicators. The air pressure of the constant pressure air spring 55 and the adjustable pressure air spring 52 can be adjusted through the reducing valve. After the screen curtain deviates, only the air pressure in the adjustable pressure air spring 52 needs to be adjusted. The air pressure difference between the constant pressure air spring 55 and the adjustable pressure air spring 52 is adjusted to regulate the air pressure of the adjustable pressure air spring 52, causing the swing seat 53 to deviate.

[0029] The correction structure of this utility model is simple and reasonably designed, and can be applied to the automatic correction process of various roll materials. When the mesh curtain deviates, the air pressure of the pressure regulating air spring 52 is reduced and the air pressure of the constant pressure air spring 55 is increased relative to the pressure regulating air spring 52. This causes the swing seat 53 to drive the correction roller 4 to move horizontally in the direction of the second roller shaft 3, so that the mesh curtain returns to the normal position. This process is repeated, so that the mesh curtain always runs in the middle of the equipment, and the purpose of automatic correction is achieved.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
