Description

Technical Field

[0001] This application relates to the field of tension adjustment technology, and in particular to a tension adjustment device for a spinning machine. Background Technology

[0002] In the spinning process, the tension stability of the spindle belt drive directly affects the equipment's operational accuracy and yarn quality. Currently, most common spindle belt tension adjustment devices for spinning machines employ a single tension wheel combined with an electric push rod, cylinder, or manual adjusting lever. This tension adjustment is achieved by driving a single tension wheel or movable spindle to move unidirectionally, thus tightening or loosening the spindle belt. Such devices can, to some extent, prevent problems such as transmission slippage and unstable speed caused by an excessively loose belt, or high energy consumption and component wear caused by an excessively tight belt.

[0003] Existing tension adjustment devices for spinning machines typically tighten the spindle belt by moving a single tension wheel. However, this method results in a concentrated and singular stress point, leading to uneven stress on both sides of the spindle belt. Over time, this can cause the spindle belt to become skewed, posing a risk of breakage. Furthermore, during the adjustment of the spindle belt tension, the changes in tension across different sections of the belt are inconsistent. Summary of the Invention

[0023] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] One preferred embodiment of this application, such as Figures 1 to 8 As shown, a tension adjustment device for a spinning frame includes: a frame body 1, and further includes: mounting plate 10, fixed spindles 11, spindle belt 12, support plate 13, drive wheel 14, driven wheel 15, tensioning assembly, and adjustment mechanism; there are two mounting plates 10, which are horizontally fixedly installed on the bottom of both sides of the frame body 1; the fixed spindles 11 are rotatably installed on one end of the top of both sides of the frame body 1; the spindle belt 12 is disposed between the two fixed spindles 11; the support plate 13 is vertically fixedly installed on one end of the top of the frame body 1; the drive wheel 14 is rotatably installed on the bottom of one end of the support plate 13; the driven wheel 15 is rotatably installed on the top of one end of the support plate 13; the tensioning assembly is disposed on the top of the frame body 1 to cooperate with the two fixed spindles 11 to tension the spindle belt 12; there are two sets of adjustment mechanisms, which are respectively disposed on the top of the two mounting plates 10 to adjust the distance between the tensioning assembly and the two fixed spindles 11.

[0027] During the operation of the spinning frame, when it is necessary to adjust the tension of the spindle belt 12, the two sets of adjustment mechanisms start synchronously and move smoothly under the support and guidance of the mounting plate 10. This drives the tensioning component to move along the set trajectory, gradually changing the relative distance between the tensioning component and the fixed spindles 11 on both sides. This allows the tensioning component, in conjunction with the fixed spindles 11, the drive wheel 14, and the driven wheel 15, to smoothly tighten or loosen the spindle belt 12. During the adjustment process, the length and tension of the multiple spindle belt segments always change synchronously and consistently, avoiding situations where the spindle belt 12 becomes too loose and slips, too tight and wears, or has uneven force on one side. This achieves stable adjustment of the tension of the spindle belt 12, ensuring the continuous and reliable operation of the spinning frame.

[0028] Further reference Figures 1-4 and Figure 6The tensioning assembly includes two movable spindles 201. Limit openings 901 are provided at the other ends of both sides of the top of the frame body 1, and the limit openings 901 are arc-shaped. The two movable spindles 201 are vertically arranged at the other ends of the top of the frame body 1. The adjustment mechanism includes a mounting plate 202, a connecting rod 203, a push block 204, two mounting plates 205, a rotating rod 206, and a drive assembly. The bottom sides of the two mounting plates 202 are slidably mounted to the top sides of the two mounting plates 10 via a sliding assembly. The two connecting rods 203 are vertically arranged within the two limit openings 901. The tops of the two connecting rods 203 are rotatably mounted to the bottoms of the two movable spindles 201, and the bottoms of the two connecting rods 203 are slidably mounted to the bottoms of the two movable spindles 201 via a sliding assembly. The second moving component is slidably mounted on the top of the two mounting plates 202. Two pushing blocks 204 are fixedly mounted at the middle of the bottom of the two mounting plates 202. One end of each pushing block 204 has a sliding opening. Two mounting plates 305 are fixedly mounted at both ends of the top of one of the mounting plates 10. One end of a rotating rod 206 is horizontally rotatably mounted on one end of one of the mounting plates 305. The other end of the rotating rod 206 passes through the sliding opening and one end of the other mounting plate 305. The rotating rod 206 is rotatably mounted to the other mounting plate 305. The inner circumference of the sliding opening and one end of the rotating rod 206 are both provided with matching threads. The driving component is positioned between the two rotating rods 206. In the initial state, the two moving spindles (201)... The spacing between the two fixed spindles 11, the spacing between the movable spindle (201) and the corresponding fixed spindle 11 are equal. The two connecting rods (203) slide along the arc edges of the two limiting openings (901) to drive the two movable spindles (201) to move synchronously. The spacing between the two movable spindles (201) and the spacing between the movable spindle (201) and the corresponding fixed spindle 11 are always equal.

[0029] First, the drive assembly is activated, which drives the rotating rods 206 inside the two sets of adjustment mechanisms to rotate synchronously. The rotating rods 206 rotate smoothly under the limiting support of the mounting plates 205 on both sides. Through the threaded engagement between the outer wall and the sliding opening on the inner side of the push block 204, the push block 204 is pushed to make horizontal linear motion, thereby driving the mounting plate 202 to move synchronously. The bottom of the mounting plate 202 slides smoothly on the top of the mounting plate 10 via the sliding assembly 1, ensuring the stability of the horizontal movement. During the horizontal movement of the mounting plate 202, the sliding assembly 2 at its top synchronously drives the connecting rod 203 to move. The connecting rod 203 is controlled by the arc-shaped limiting opening 1 on the frame body 1. The edge limiting guide of 901 causes the connecting rod 203 to not only move horizontally with the mounting plate 202, but also to shift laterally along the arc-shaped trajectory of the limiting opening 901. This causes the top movable spindle 201 to simultaneously achieve horizontal and forward / backward bidirectional displacement, allowing the two movable spindles 201 to move away from each other synchronously. In the initial state, the distance between the two movable spindles 201, the two fixed spindles 11, and the distance between the movable spindle 201 and the corresponding fixed spindle 11 is a constant value z. The forward / backward offset distance of a single movable spindle 201 is set as x, and the horizontal distance of the movable spindle 201 away from the fixed spindle 11 is set as y. Based on the requirement of balanced spacing, a trajectory equation 3x is established. 2 +4xz−y 2 -2yz=0, the arc trajectory of the limit opening 901 is completely laid out according to the curve of this equation. In the initial state, the distance between the two movable spindles 201, the distance between the two fixed spindles 11, and the distance between the movable spindle 201 and the corresponding fixed spindle 11 are equal. During the movement of the movable spindle 201, the trajectory displacement is strictly defined by the above equation, and the distance between the two movable spindles 201 and the distance from the movable spindle 201 to the corresponding fixed spindle 11 is always equal. This allows the length and tension of each section of the spindle belt to change synchronously and consistently. The magnitude and distance of the lengthening and shortening are exactly the same, and the multi-point balanced force is achieved throughout the process. This avoids the problem of uneven force on one side of the spindle belt and excessive local stress, making the tension adjustment of the spindle belt more stable, effectively reducing the risk of breakage, and ensuring the stable operation of the spinning machine.

[0030] Further reference Figure 3 and Figure 7 The drive assembly includes a rotary motor 401, two pulleys 402 and a belt 403. The top of one of the mounting plates 10 is provided with a mounting groove. The rotary motor 401 is fixedly installed on the bottom inner wall of the mounting groove. The output shaft of the rotary motor 401 is fixedly installed on the other end of one of the rotating rods 206. The two pulleys 402 are respectively sleeved on the other ends of the two rotating rods 206. The belt 403 is engaged between the two pulleys 402.

[0031] The rotating motor 401 is started and is fixed in the mounting slot of the mounting plate 10 for stable operation. Its output shaft rotates, driving the rotating rod 206 connected to it to rotate. The pulley 402 on the rotating rod 206 rotates synchronously, and then through the meshing belt 403, it drives another set of pulleys 402 to rotate synchronously and in the same direction as the corresponding rotating rod 206, realizing the synchronous drive of the rotating rods 206 of the two adjustment mechanisms.

[0032] Further reference Figure 2 , Figures 4-6 and Figure 8 Mounting plate 202 is L-shaped. Limit opening 2 is opened at the other end of both sides of the frame body 1. The same sleeve 501 is fixedly installed between the top of the two mounting plates 202 that are close to each other. The two sides of the sleeve 501 are respectively located in the two limit openings 2. Insert rods 502 are inserted into both sides of the sleeve 501. The two insert rods 502 that are far apart from each other pass through the two mounting plates 202 and are fixedly installed with the two connecting rods 203. The same buffer spring 503 is fixedly installed between the two insert rods 502 that are close to each other. A rotating roller 601 is sleeved on the connecting rod 203. The connecting rod 203 and the rotating roller 601 are rotatably installed. The diameter of the rotating roller 601 is smaller than the groove width of the limit opening 901.

[0033] In the initial state and during operation, the tension adjustment device of this spinning frame has the insert rods 502 on both sides of the sleeve 501 passing through the mounting plate 202 and fixedly connected to the connecting rods 203. The buffer springs 503 installed between them are always in a compressed state, providing continuous preload force, which pushes the two connecting rods 203 and the rotating roller 601 sleeved on them to always be tightly pressed against the inner wall of the opposite side of the limiting opening 901, forming a stable contact guide. Since the diameter of the rotating roller 601 is smaller than the groove width of the limiting opening 901, there is a small gap when it moves, ensuring that the connecting rod 203 always rolls in contact with the inner wall of the limiting opening 901 through the rotating roller 601 when it moves along the arc trajectory. This effectively avoids the connecting rod 203 directly rubbing against the groove wall, causing scratches, blockages or jamming, and ensures the smooth and precise movement of the movable spindle 201. When there are slight fluctuations in the rotational transmission and tension, or when manual adjustment of the tension of the spindle belt 12 is required based on the actual spinning conditions, the tension of the spindle belt 12 will be transmitted to the movable spindle 201 and the connecting rod 203. At this time, the buffer spring 503, using its initial compression margin, allows the two insert rods 502 and the connecting rod 203 to move slightly towards each other, i.e., move closer to each other a little bit, thereby providing elastic buffering for instantaneous over-tightness or excessive pressure. This small displacement buffering effectively absorbs the instantaneous stress fluctuations caused by the rotation of the spindle belt 12, avoiding component impact or stress concentration caused by rigid transmission. At the same time, combined with the arc-shaped trajectory constraint of the limiting opening 901, the dynamic balance and stability of tension adjustment are ensured, achieving a perfect combination of rigid transmission and elastic buffering, ensuring reliable operation of the spinning machine under various working conditions and a long service life of the spindle belt 12.

[0034] Further reference Figure 3 and Figure 4 The first sliding component includes: a slide rail 701 and a slider 702. The two slide rails 701 are fixedly installed on both sides of the top of the second mounting plate 202, and the two sliders 702 are slidably installed on the two slide rails 701. The two sliders 702 are fixedly installed on both sides of the bottom of the second mounting plate 202. The second sliding component includes: a slide rail 703 and a slider 704. The slide rail 703 is fixedly installed on the top of the second mounting plate 202, and the slider 704 is slidably installed on the slide rail 703. The slider 704 is fixedly installed on the bottom of the connecting rod 203.

[0035] Mounting plate 202 slides stably on slide rail 701 via slider 702, and connecting rod 203 slides stably on slide rail 703 via slider 704.

[0036] Further reference Figure 1 and Figure 2 The spindle belt 12 is wound between two movable spindles 201, two fixed spindles 11, driving wheel 14 and driven wheel 15.

[0037] After the device is assembled, the spindle belt 12 is sequentially wound around the outer walls of two movable spindles 201, two fixed spindles 11, driving wheel 14, and driven wheel 15. When the device is running, the driving wheel 14 rotates to provide power, which drives the driven wheel 15 to rotate synchronously through the transmission of the spindle belt 12. At the same time, it drives the two fixed spindles 11 and two movable spindles 201 to rotate. During the tension adjustment process, the two movable spindles 201 change position, which synchronously drives the wound spindle belt 12 to tighten or loosen. Throughout the process, the winding and limiting of multiple spindles and wheel bodies ensures that the transmission of the spindle belt 12 is stable and does not fall off. With the help of tension adjustment, a smooth tension state adjustment is achieved.

[0038] Working principle: During the operation of the spinning frame, when it is necessary to adjust the tension of the spindle belt 12, the rotating motor 401 is started first. The output shaft of the rotating motor 401 rotates, driving the connected rotating rod 206 to rotate. With the transmission action of the pulley 402 and the belt 403, the rotating rods 206 inside the two sets of adjustment mechanisms are driven synchronously in the same direction. The rotating rods 206 rotate smoothly under the limiting support of the mounting plate three 205, and push the push block 204 to make horizontal linear motion through the threaded engagement, thereby driving the mounting plate two 202 to move synchronously. The mounting plate two 202 moves synchronously through the slider one 70. 2. The connecting rod 203 slides stably on the slide rail 701 via the slider 704, ensuring smooth and seamless overall movement. During the movement of the mounting plate 202, the top sliding component synchronously drives the connecting rod 203. Guided by the arc-shaped limiting opening 901, the connecting rod 203 not only moves horizontally with the mounting plate 202 but also shifts laterally along the arc-shaped trajectory of the limiting opening 901. This causes the two movable spindles 201 to move away from each other synchronously, and the entire movement follows the preset trajectory equation, ensuring that the two movable spindles 201 always move smoothly. The spacing between the two sections is always equal to the spacing between the movable spindle 201 and the corresponding fixed spindle 11, so that the length and tension of each section of the spindle belt 12 change synchronously and uniformly, and the tension or relaxation of the spindle belt 12 is achieved synchronously. In the initial state, the buffer spring 503 is in a compressed state, and continuously pushes the connecting rod 203 and the rotating roller 601 against the inner wall of the limiting opening 901 through the insertion rod 502. The rolling contact of the rotating roller 601 avoids friction and jamming of the components. When the tension of the spindle belt 12 rotates and the transmission is slightly fluctuating, the buffer spring 503 can use the compression margin to drive the insertion rod 502 and the connecting rod 203 makes a slight opposite movement to provide elastic buffering for the instantaneous stress of the spindle belt 12, absorb tension fluctuations, and avoid component damage caused by rigid transmission. When the device is running, the drive wheel 14 rotates to provide power, which drives the driven wheel 15, the fixed spindle 11, and the movable spindle 201 to rotate synchronously through the spindle belt 12. When the movable spindle 201 moves, it drives the spindle belt 12 to tighten or loosen synchronously, ensuring that the transmission of the spindle belt 12 is stable and does not fall off throughout the process. Finally, it achieves balanced and stable adjustment of the tension of the spindle belt 12, avoiding problems such as slippage, wear, and uneven force on the spindle belt 12, and ensuring the continuous and reliable operation of the spinning machine.
