Description

Technical Field

[0001] This utility model belongs to the field of spinning production technology, and specifically relates to a tensioning device for a winding machine used in spinning production. Background Technology

[0002] Spinning is the core process of chemical fiber manufacturing, which transforms high molecular polymers (such as polyester, nylon, acrylic acid, etc.) into continuous fibers. In spinning production (especially chemical fiber spinning), the tensioning device of the winding machine is one of the core components of the entire production line. Its performance directly affects the stability of the filament tension, the quality of the package forming, the breakage rate, and the subsequent processing performance.

[0003] Existing tensioning devices for spinning production winding machines utilize constant pressure generated by cylinders or hydraulic cylinders, which is applied to tension arms or friction elements via levers or directly to provide relatively constant tension, thereby adjusting the tension of the yarn to be wound. However, in actual use, adjustment is usually quite troublesome (requiring adjustment of air / hydraulic pressure), requiring an additional air / hydraulic source system. The tension will vary slightly with the position of the cylinder / cylinder rod, requiring operators to spend a considerable amount of time calibrating it, making it rather cumbersome to use. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a tensioning device for a winding machine in spinning production. The device uses an electric push rod and a dual-axis motor to drive the tension adjusting rollers to move in both horizontal and vertical directions, thereby quickly, stably, and efficiently adjusting the tension of the spun yarn wound between the tension adjusting rollers.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a tensioning device for a winding machine in spinning production, including a frame, the frame being provided with multiple sliding frames through a position adjustment mechanism, each sliding frame having symmetrically distributed roller bearing seats at one end away from the vertical center of the frame, and tension adjusting rollers being rotatably arranged between adjacent roller bearing seats, the position adjustment mechanism being used to drive the movement of the tension adjusting rollers; multiple support feet are provided on the lower surface of the frame, and rubber pads are provided on the lower surface of each support foot.

[0006] As a further improvement of this utility model, the position adjustment mechanism includes guide rails symmetrically arranged on the inner walls of both sides of the frame, symmetrically distributed slide tables slidably arranged between the guide rails, and sliding frames slidably connected to adjacent slide tables respectively; symmetrically distributed slide rails are arranged inside each slide table, a slide column is fixedly arranged on each slide frame, symmetrically distributed drive blocks are slidably arranged between two adjacent slide rails, symmetrically distributed sliders are slidably arranged on each slide column, and multiple connecting rods are rotatably arranged on the outer side of each drive block, with the end of the connecting rod away from the drive block rotatably connected to the adjacent slider respectively.

[0007] As a further improvement of this utility model, the slide table is provided with symmetrically distributed support plates inside. Adjusting screws are rotatably provided between the support plates and the adjacent inner walls of the slide table. The adjusting screws are threadedly connected to the adjacent drive blocks respectively. A dual-axis motor is provided in the middle of the slide table. The output shafts of the dual-axis motors are fixed to the adjacent adjusting screws by couplings.

[0008] As a further improvement of this utility model, a support is provided in the middle of the frame, and electric push rods are provided on both the upper and lower sides of the support. The telescopic ends of the electric push rods are respectively connected and fixed to the adjacent slides.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the tension sensor installed on the rear roller bearing seat detects the force borne by the tension regulating roller connected to it. Then, the tension regulating roller is moved horizontally and vertically by the cooperation of the electric push rod and the dual-axis motor, so as to quickly, stably and efficiently adjust the tension of the spinning yarn wound between the tension regulating rollers.

[0011] Secondly, the telescopic end of the electric push rod drives the slide table connected to it to move, so that the slide table drives the tension adjusting roller installed on it to adjust in the vertical direction, thereby adjusting the tension of the yarn to be wound.

[0012] Third, the output shaft of the dual-axis motor drives the adjusting screw connected to it to rotate, causing the tension adjusting rollers on both sides to move towards each other or away from each other in the horizontal direction. By adjusting the tension adjusting rollers in the horizontal direction, the tension of the yarn to be wound can be further adjusted. Attached Figure Description

Detailed Implementation

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 1 , 4 As shown, the device includes a frame 101, which is equipped with multiple sliding frames 105 via a position adjustment mechanism. Each sliding frame 105 has symmetrically distributed roller bearing seats 106 at one end away from the vertical center of the frame 101. Tension adjusting rollers 107 are rotatably mounted between adjacent roller bearing seats 106. The position adjustment mechanism is used to drive the movement of the tension adjusting rollers 107. Tension sensors are mounted on the rear roller bearing seats 106, and the tension sensors are connected to the adjacent tension adjusting rollers 107. The tension sensor model is WRMGZ-2 tension sensor.

[0021] like Figure 2 , 3 As shown, the position adjustment mechanism includes guide rails 103 symmetrically arranged on the inner walls of both sides of the frame 101. Symmetrically distributed slide tables 104 are slidably arranged between the guide rails 103. Sliding frames 105 are slidably connected to adjacent slide tables 104. Symmetrically distributed slide rails 202 are arranged inside each slide table 104. A sliding column 201 is fixedly mounted on each sliding frame 105. Symmetrically distributed drive blocks 204 are slidably arranged between adjacent slide rails 202. Symmetrically distributed sliders 203 are slidably mounted on each sliding column 201. Multiple connecting rods 205 are rotatably arranged on the outer side of the slide block 204. The end of the connecting rod 205 away from the drive block 204 is rotatably connected to the adjacent slider 203. Symmetrically distributed support plates are arranged inside the slide block 104. Adjusting screws 206 are rotatably arranged between the support plates and the inner wall of the adjacent slide block 104. The adjusting screws 206 are threadedly connected to the adjacent drive blocks 204. A dual-axis motor 207 is arranged in the middle of the slide block 104. The output shaft of the dual-axis motor 207 is fixed to the adjacent adjusting screws 206 by couplings.

[0022] like Figure 2 , 4 As shown, a support 301 is provided in the middle of the frame 101, and electric push rods 302 are provided on both the upper and lower sides of the support 301. The telescopic ends of the electric push rods 302 are connected and fixed to the adjacent slides 104 respectively.

[0023] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the lower surface of the frame 101 is provided with multiple legs 102, and the lower surface of each leg 102 is provided with a rubber pad.

[0024] When in use, the yarn to be wound is passed around the right half of the tension adjusting roller 107 on the lower left side and then upward, then around the left half of the tension adjusting roller 107 on the upper left side and then to the right, then around the right half of the tension adjusting roller 107 on the upper right side and then downward, and finally around the left half of the tension adjusting roller 107 on the lower right side and then to the right, so that the yarn to be wound is wound between the tension adjusting rollers 107.

[0025] The telescopic end of the electric push rod 302 drives the slide table 104 connected to it to move, so that the slide table 104 slides between the guide rails 103, thereby causing the slide table 104 to move and drive the tension adjusting roller 107 installed on it to adjust in the vertical direction, thereby adjusting the tension of the spun yarn to be wound.

[0026] The output shaft of the dual-axis motor 207 drives the adjusting screw 206 connected to it to rotate. Then, through the thread relationship between the adjusting screw 206 and the driving block 204, the driving block 204 is driven to slide between adjacent slide rails 202. During the movement of the driving block 204, the driving block 204 rotates with the connecting rod 205, the connecting rod 205 rotates with the adjacent connecting rod 205, and the connecting rod 205 rotates with the slider 203. This causes the scissor brace structure formed by the driving block 204, the connecting rod 205 and the slider 203 to move the sliding frames 105 on both sides toward each other or away from each other. This causes the sliding frames 105 to move the tension adjusting roller 107, causing the tension adjusting rollers 107 on both sides to move toward each other or away from each other in the horizontal direction. By adjusting the tension adjusting roller 107 in the horizontal direction, the tension of the yarn to be wound can be further adjusted.

[0027] During the adjustment process, the tension sensor installed on the rear roller bearing seat 106 detects the force borne by the tension adjusting roller 107 connected to it. Then, the electric push rod 302 and the dual-axis motor 207 work together to drive the tension adjusting roller 107 to move in the horizontal and vertical directions, thereby quickly, stably and efficiently adjusting the tension of the spinning yarn wound between the tension adjusting rollers 107.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
