Description

Technical Field

[0001] This invention relates to the field of yarn processing technology, specifically to a guiding and positioning device for yarn processing. Background Technology

[0002] The current methods are inconvenient and fail to meet the high efficiency and high quality requirements of modern yarn processing. Therefore, developing a new type of guiding and positioning device for yarn processing is crucial to solving these problems.

[0003] Existing yarn guiding and positioning devices typically consist of a fixed bracket and guiding components. However, these devices have several shortcomings in practical applications. For example, the fixed bracket often uses a single welded structure, which is not only inconvenient to install but also difficult to adjust in a flexible manner according to actual needs. In addition, the adjustment of the guiding components is usually cumbersome, requiring specialized tools, which greatly reduces work efficiency. Furthermore, after prolonged use, traditional devices are prone to decreased guiding accuracy due to wear and loosening, affecting the quality of yarn processing.

[0004] To address the aforementioned issues, there is an urgent need to develop a yarn processing guide and positioning device that is simple in structure, easy to install, flexible in adjustment, and has high guiding accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide a guiding and positioning device for yarn processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a guide and positioning device for yarn processing, comprising a crossbeam, with mounting plates fixed at both ends of the crossbeam, a plurality of collars sleeved on the crossbeam, a clamping screw screw screwed onto the bottom plate of the collar, the clamping screw screw clamping the crossbeam, a bracket slidably connected above the collar, and a guide wheel rotatably connected to the top of the bracket.

[0007] Preferably, the mounting plate has an "L" shaped plate structure, bolt holes are provided on the bottom plate of the mounting plate, and the two mounting plates are symmetrically distributed about the crossbeam.

[0008] Preferably, both the top and bottom surfaces of the crossbeam are provided with notches, the length of the long side of the notch is equal to the length of the long side of the crossbeam, the top surface of the bottom plate of the collar is provided with a reserved groove, a rubber band is fixed between the two parallel sidewalls of the reserved groove, and a rubber clamp is fixed to the bottom surface of the top plate of the collar, the rubber clamp is inserted into the notch.

[0009] Preferably, limiting plates are fixed on both sides of the collar. The limiting plates are in a "C"-shaped plate structure, and the bracket is in a "C"-shaped plate structure. Two parallel side plates of the bracket are respectively inserted into the two limiting plates. A screw is screwed on the surface of the limiting plate, and one end of the screw is inserted into the positioning groove. The positioning groove is opened on the surface of the bracket. There are multiple positioning grooves, and the multiple positioning grooves are arranged equidistantly and equally sized along the long side of the bracket.

[0010] Preferably, two vertical plates are fixed on the top surface of the bracket, and a limiting shaft is fixed between the two vertical plates. The guide wheel is sleeved on the shaft body of the limiting shaft.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] The yarn processing guiding and positioning device proposed by the present invention adopts a combined structure of a cross beam and mounting support plates, making the overall structure more concise and clear. During installation, only need to weld the mounting support plates at both ends of the cross beam and fix the mounting support plates on the machine frame through bolts, which greatly simplifies the installation process. At the same time, the design of the collar enables the guiding component to slide and be fixed along the cross beam conveniently, further improving the installation convenience. Both the collar and the bracket are designed with adjustment mechanisms, which can be flexibly adjusted according to actual needs. By screwing the clamping screw and loosening / retightening the screw, the fixing and release of the collar and the bracket can be conveniently achieved, so as to meet the guiding and positioning requirements in different yarn processing processes. In addition, the design of multiple positioning grooves makes the height adjustment of the bracket more accurate, further improving the adaptability of the device. The guide wheel is fixed on the bracket through the limiting shaft, ensuring the stability and guiding accuracy of the guide wheel. At the same time, the design of the rubber belt and rubber clamping block increases the friction between the clamping screw and the collar and the cross beam, effectively preventing loosening and displacement phenomena, and further improving the stability and guiding accuracy of the device.

[0021] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 7 This invention provides a technical solution: a guiding and positioning device for yarn processing, comprising a crossbeam 1, with mounting plates 2 fixed at both ends of the crossbeam 1. The mounting plates 2 have an "L"-shaped plate structure, and bolt holes are provided on the bottom plate of the mounting plates 2. The two mounting plates 2 are symmetrically distributed about the crossbeam 1. Multiple collars 3 are sleeved on the body of the crossbeam 1. Clamping screws 7 are screwed onto the bottom plate of the collars 3, and the clamping screws 7 clamp the crossbeam 1. The top and bottom surfaces of the crossbeam 1 are provided with notches 4, and the length of the long side of the notch 4 is equal to the length of the long side of the crossbeam 1. The top surface of the bottom plate of the collar 3 is provided with a reserved groove 5. A rubber band 6 is fixed between the two parallel sidewalls of the reserved groove 5. A rubber clamp 8 is fixed on the bottom surface of the top plate of the collar 3 and is inserted into the notch 4.

[0023] In use, the collar 3 is pre-fitted onto the crossbeam 1, and then the support plates 2 are welded and fixed at both ends of the crossbeam 1. The support plates 2 are used to support the crossbeam 1. The base plate of the support plate 2 is fixed to the frame with bolts. After the collar 3 is slid along the crossbeam 1 to the desired position, the clamping screw 7 is screwed to clamp the crossbeam 1. At this time, the rubber belt 6 is stretched and produces elastic deformation. The rubber belt 6 is clamped between the clamping screw 7 and the crossbeam 1, increasing the friction between the clamping screw 7 and the crossbeam 1. In addition, the rubber clamp 8 is pressed into the notch 4 by the top plate of the collar 3, increasing the friction between the collar 3 and the crossbeam 1.

[0024] A bracket 10 is slidably connected above the collar 3. A guide wheel 13 is rotatably connected to the top end of the bracket 10. Limiting plates 9 are fixed on both sides of the collar 3. The limiting plates 9 are in the shape of a "C" - shaped plate structure. The bracket 10 is in the shape of a "C" - shaped plate structure. Two parallel - distributed side plates of the bracket 10 are respectively inserted into the two limiting plates 9. A screw 14 is screwed on the surface of the limiting plate 9. One end of the screw 14 is inserted into a positioning groove 15. The positioning groove 15 is opened on the surface of the bracket 10. There are multiple positioning grooves 15, and the multiple positioning grooves 15 are arranged in equal - distance and equal - size along the long side of the bracket 10. Two vertical plates 11 are fixed on the top surface of the bracket 10. A limiting shaft 12 is fixed between the two vertical plates 11. The guide wheel 13 is sleeved on the shaft body of the limiting shaft 12.

[0025] During use, adjust the height of the guide wheel 13 as needed. The specific operation is as follows: loosen the screw 14 to disengage it from the positioning groove 15, then pull the bracket 10 to adjust its position. After screwing back the screw 14 and inserting it into the corresponding positioning groove 15, the braking of the bracket 10 is achieved. The yarn passes through the groove of the guide wheel 13, and the guide wheel 13 plays a role in guiding and positioning the yarn.

[0026] The process of using the guiding and positioning device for yarn processing is as follows:

[0027] A plurality of collars 3 are sleeved on the rod body of the cross beam 1 to ensure that they can slide freely along the cross beam 1. Check whether the reserved grooves 5 and rubber belts 6 on the bottom plates of each collar 3 are in good condition. The rubber belt 6 should have a certain elasticity. Fix two mounting support plates 2 at both ends of the cross beam 1 respectively, ensuring that they are symmetrically distributed with respect to the cross beam 1. Use welding or other suitable fixing methods to ensure that the mounting support plate 2 is firmly connected to the cross beam 1. Use bolts to fix the bottom plate of the mounting support plate 2 to the machine frame through the bolt holes of the mounting support plate 2. Ensure that the mounting support plate 2 is stable and does not shake. As needed, move the collar 3 along the cross beam 1 to the required position. Ensure that the collar 3 is not obstructed during the sliding process. Screw the clamping screw 7 on the bottom plate of the collar 3 to clamp the cross beam 1. During the clamping process, the rubber belt 6 will be tensioned to produce elastic deformation, increasing the friction force between the clamping screw 7 and the cross beam 1. Check whether the rubber clamping block 8 is correctly inserted into the notch 4 of the cross beam 1. If necessary, adjust the position of the rubber clamping block 8 to ensure that it is squeezed by the top plate of the collar 3 in the notch 4, increasing the friction force between the collar 3 and the cross beam 1. Check whether the bracket 10 is intact, ensuring that it has a "U" - shaped structure and the two parallel - distributed side plates can be inserted into the limiting plate 9. Insert the two side plates of the bracket 10 into the limiting plates 9 on both sides of the collar 3 respectively. Ensure that the bracket 10 can slide freely in the limiting plate 9. Adjust the height of the bracket 10 as needed. Loosen the screw 14 on the surface of the limiting plate 9 to disengage it from the positioning groove 15 on the surface of the bracket 10. Pull the bracket 10 to adjust its position until the required height is reached. Screw back the screw 14 to insert it into the corresponding positioning groove 15 to brake the bracket 10. Check whether the guide wheel 13 is intact, ensuring that it can be sleeved on the shaft body of the limiting shaft 12. Install the guide wheel 13 on the limiting shaft 12 between the two vertical plates 11 on the top surface of the bracket 10. Ensure that the guide wheel 13 can rotate freely. Pass the yarn through the groove of the guide wheel 13 to ensure that the yarn runs smoothly under the guidance of the guide wheel 13.
