Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and more specifically, to a motion correction and adjustment device. Background Technology

[0002] Stroke correction is an essential structural component on a texturing machine, such as... Figure 1 As shown, the stroke correction 7 has three sets of fourth through holes 701 for mounting on the wall plate 8. The wall plate has three sets of threaded holes 801 corresponding to the three sets of fourth through holes 701. The stroke correction 7 is fixed to the wall plate 8 by passing a third screw (not shown) through the fourth through holes 701 and then threading it into the threaded holes 801. During operation, the motor rotates forward and backward, driving the chain to rotate forward and backward. The sprocket on the stroke correction 7 then drives the nut of the ball screw set in the internal structure to rotate, thus moving the threaded shaft 703 back and forth a certain distance along the wall plate 8. Therefore, the threaded shaft 703 is subjected to forces in both the axial and radial directions. To constrain the radial rotation of the threaded shaft 703, a nylon liner 702 is used to press the threaded shaft 703. When installing the nylon liner 702, the eccentric shaft 704 is first passed through the nylon liner 702 and fixed to the stroke correction 7, and then the eccentric shaft 704 is secured by the fourth screw 705.

[0003] When the threaded shaft 703 achieves axial movement, it is simultaneously subjected to radial rotational force. Therefore, the material of the bushing used to restrict the radial force of the threaded shaft 703 cannot be the same steel material as the threaded shaft 703; instead, a nylon material with certain wear resistance and hardness must be used. Due to the difference in hardness between the two materials, the nylon bushing 702 will inevitably wear. At this point, the eccentric shaft 704 needs to be tightened with the fourth screw 705 to ensure that the nylon bushing 702 still presses against the threaded shaft 703, thus restricting the radial rotation of the threaded shaft 703. Since the mounting surfaces of the fourth screw 705 and the eccentric shaft 704 are located precisely within the hole in the wall plate 8, adjustments must be made by completely removing the stroke correction 7 from the wall plate 8. Furthermore, after removing and reinstalling the stroke correction 7, the chain needs to be readjusted, which is time-consuming, difficult, and very troublesome.

[0004] Due to the continuous, long-term operation of texturing machines, the nylon liner will wear down. Adjusting the nylon liner after a certain period to ensure the machine's normal operation is essential. However, structural defects make the nylon liner difficult to adjust, cumbersome to adjust, and time-consuming, causing strong dissatisfaction among users.

[0005] Therefore, a new solution is needed to address the above problems. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dynamic stroke correction and adjustment device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A stroke correction and adjustment device includes a fixing plate installed on the back of a wall panel. The fixing plate has a first through hole through which a threaded shaft for stroke correction passes. The fixing plate has a nylon plate at the edge of the first through hole for abutting the threaded shaft. Both sides of the nylon plate have waist-shaped holes. A pressure plate is provided above the nylon plate. Both sides of the pressure plate have second through holes corresponding to the waist-shaped holes. A first screw is provided in the second through hole. After the first screw passes through the second through hole and the waist-shaped hole, it is threaded to the fixing plate to fix the pressure plate and the nylon plate to the fixing plate.

[0009] Furthermore, the nylon plates are provided in two sets, located on both sides of the first through hole and arranged symmetrically, with the two sets of nylon plates abutting against the milled flat planes on both sides of the threaded shaft.

[0010] Furthermore, the thickness of the nylon plate is less than the thickness of the stroke-corrected nylon liner.

[0011] Furthermore, the wall panel has three sets of threaded holes, and the fixing plate has a third through hole corresponding to two of the sets of threaded holes. A second screw is provided in the third through hole. After the second screw passes through the third through hole, it is threaded into the threaded hole to fix the fixing plate to the wall panel.

[0012] Furthermore, the stroke correction is located on the front of the wall panel, and the stroke correction has three sets of fourth through holes corresponding to the three sets of threaded holes. A third screw is provided in the fourth through hole, and the third screw passes through the fourth through hole and is threaded to the threaded hole to fix the stroke correction to the wall panel.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this utility model, by setting a nylon plate, the nylon plate and the nylon liner cooperate to restrict the radial force of the threaded shaft, thereby reducing the wear of the nylon liner and slowing down the wear of the nylon liner, thus extending the adjustment period of the nylon liner; at the same time, the nylon plate is installed on the back of the wall panel by a fixing plate to facilitate the adjustment of the nylon plate.

[0015] 2. In this utility model, by setting a waist-shaped hole on the nylon plate, the nylon plate has a certain adjustment space, and its position can always be adjusted, so as to facilitate the nylon plate to fit tightly against the threaded shaft.

[0016] 3. In this utility model, by setting the thickness of the nylon plate to be less than that of the nylon liner, the wear of the nylon plate is more obvious under the same working conditions, which will be reflected earlier and require adjustment and replacement, thereby effectively protecting the nylon liner and reducing its wear.

[0017] 4. The adjustment device of this utility model has few components, is easy to assemble and adjust, has low cost, and can be adapted without changing the existing wall panel structure design, thus improving the adaptability and versatility of the adjustment device.

Detailed Implementation

[0023] 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.

[0024] Example: A stroke correction and adjustment device, such as Figures 2-4As shown, the wall panel 8 is mounted on the back of the wall panel 8. A stroke correction 7 is mounted on the front of the wall panel 8. The wall panel 8 is corresponding to the stroke correction 7. The wall panel 1 has a first through hole 2 for the threaded shaft 703 of the stroke correction 7 to pass through. The wall panel 1 has a nylon plate 3 at the edge of the first through hole 2 for abutting the threaded shaft 703. The nylon plate 3 has a waist-shaped hole 301 on both sides. A pressure plate 4 is provided above the nylon plate 3. The pressure plate 4 has a second through hole 401 on both sides corresponding to the waist-shaped hole 301. A first screw 5 is provided in the second through hole 401. After the first screw 5 passes through the second through hole 401 and the waist-shaped hole 301, the wall panel 8 is threaded to the wall panel 1 to fix the pressure plate 4 and the nylon plate 3 to the wall panel 1.

[0025] During installation, one side of the nylon plate 3 is pressed tightly against the milled flat surface of the threaded shaft 703 of the stroke correction 7, and then the nylon plate 3 is fixed with the first screw 5. By providing a waist-shaped hole 301 on the nylon plate 3, the position of the nylon plate 3 can be adjusted by changing the position of the first screw 5 in the waist-shaped hole 301, thereby ensuring that one side of the nylon plate 3 is always pressed tightly against the milled flat surface of the threaded shaft 703 of the stroke correction 7. That is, when it is found that one side of the nylon plate 3 deviates from the contact surface of the threaded shaft 703 due to wear, first loosen the first screw 5, then push the nylon plate 3 toward the contact surface of the threaded shaft 703, so that the nylon plate 3 is pressed tightly against the threaded shaft 703 again, and then tighten the first screw 5 to fix the nylon plate 3.

[0026] By setting up the nylon plate 3, the nylon plate 3 and the nylon bushing 702 cooperate to restrict the radial force of the threaded shaft 703, thereby reducing the wear of the nylon bushing 702 and slowing down its wear, thus extending the adjustment period of the nylon bushing 702. By setting the waist-shaped hole 301 on the nylon plate 3, a certain adjustment space is provided for the nylon plate 3, allowing its position to be adjusted at all times, thus facilitating the tight fit of the nylon plate 3 against the threaded shaft 703. At the same time, by installing the fixing plate 1 on the back of the wall panel 8, the nylon plate 3 is mounted on the fixing plate 1, facilitating the adjustment of the nylon plate 3.

[0027] Preferably, the thickness of the nylon plate 3 should be designed to be maximized, and due to space constraints, it should be less than the thickness of the nylon liner 702. The thickness of the nylon plate 3 refers to the width of its contact surface with the threaded shaft 703, and the thickness of the nylon liner 702 refers to the width of its contact surface with the threaded shaft 703.

[0028] If the thickness of the nylon plate 3 is greater than the thickness of the nylon liner 702, the function of the nylon liner 702 can be ignored, and it can be completely replaced by the nylon plate 3. Wear adjustment is transformed from complex internal adjustment to simple external adjustment.

[0029] If the thickness of the nylon plate 3 is less than the thickness of the nylon liner 702, the role of the nylon liner cannot be ignored; rather, it protects and slows down the wear of the nylon liner 702. The principle is that under the same working conditions, the wear of the nylon plate 3 is more noticeable, leading to earlier adjustments and replacements, thus effectively protecting the nylon liner 702 and reducing its wear. Wear adjustment is thus transformed from complex internal adjustments to simple external adjustments.

[0030] Based on the thickness design of the nylon plate 3, if the thickness of the nylon liner 702 is 10cm and the thickness of the nylon plate 3 is designed to be 4cm, it is equivalent to extending the adjustment cycle of the nylon liner 702 by 40% under the same working conditions, and the wear adjustment is also changed from complex internal adjustment to simple external adjustment.

[0031] Assuming that the nylon liner 702 is worn out during use and is not adjusted, that is, after the nylon liner 702 loses its function, the nylon plate 3 will completely replace the function. Under the same working stress, the adjustment cycle of the nylon liner 702 will be shortened. The wear adjustment will also change from complex internal adjustment to simple external adjustment. That is, the worn nylon liner 702 will not be adjusted or replaced, only the nylon plate 3 will be adjusted and replaced. The radial force of the threaded shaft 703 will be limited by the milled flat square plane of the nylon plate 3 tightly attached to one side of the threaded shaft 703.

[0032] Furthermore, such as Figure 2 and Figure 3 As shown, two sets of nylon plates 3 are provided, located on both sides of the first through hole 2 and arranged symmetrically. The two sets of nylon plates 3 abut against both sides of the threaded shaft 703. By providing two sets of nylon plates 3, the radial force of the threaded shaft 703 is restricted from both sides of the threaded shaft 703, thereby improving the radial force restriction effect. At the same time, it further reduces the wear of the nylon liner 702, slows down the wear of the nylon liner 702, and delays the adjustment and replacement of the nylon liner 702.

[0033] Furthermore, such as Figure 1 As shown, the wall panel 8 has three sets of threaded holes 801, and the stroke correction 7 has three sets of fourth through holes 701 corresponding to the three sets of threaded holes 801. That is, the fourth through holes 701 and the threaded holes 801 are in one-to-one correspondence. There are three sets of fourth through holes 701. A third screw (not shown) is installed in the fourth through hole 701. After the third screw passes through the fourth through hole 701, it is threaded into the threaded hole 801 to fix the stroke correction 7 to the wall panel 8. The stroke correction 7 is fixedly installed on the front of the wall panel 8 by the cooperation of the threaded holes 801, the fourth through holes 701 and the third screw. This installation method is the existing installation method of the stroke correction 7.

[0034] As a preferred option, such as Figures 2-4As shown, the fixing plate 1 has a third through hole 101 corresponding to two sets of threaded holes 801, i.e., there are two sets of third through holes 101. A second screw 6 is installed in the third through hole 101. The second screw 6 passes through the third through hole 101 and is threaded into the threaded hole 801 to fix the fixing plate 1 to the wall panel 8. By setting the third through hole 101 on the fixing plate 1 to correspond with the threaded hole 801 on the wall panel 8, it is not necessary to re-drill holes and redesign the wall panel 8. That is, the adjustment device of this embodiment can be adapted without changing the existing structural design of the wall panel 8, which improves the adaptability and versatility of the adjustment device.

[0035] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
