Description

Technical Field

[0001] This utility model relates to the technical field of textile machine components, specifically a tension control device for textile machines. Background Technology

[0002] A textile machine is a major piece of machinery that processes raw materials such as silk, thread, and hemp into threads, and then weaves them into fabrics.

[0003] In the modern textile industry, textile machines occupy an important position in textile production. Textile products used in people's daily lives are inseparable from textile machines. The tension control device on the textile machine is a key technology to ensure stable material transmission and high-quality winding during textile production. As the amount of yarn on the anti-roller decreases, the position of the yarn on the tension device also decreases. Therefore, in order to ensure tension stability, the tension control can be adjusted to ensure the tensioning and conveying effect of the yarn.

[0004] Although the existing tension control devices for textile machines can adjust their height according to the decrease in yarn movement to ensure tension stability, the operation process requires a lot of manual intervention. It is time-consuming and labor-intensive, and will also increase unnecessary labor costs. Therefore, we have designed a tension control device for textile machines to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a tension control device for textile machines to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a tension control device for a textile machine, including a frame. Fixed plates are fixedly installed at both the front and rear ends of the top of the frame. A slider and an adjusting block are slidably disposed within the fixed plates. An electric push rod is fixedly installed within the fixed plates, and the driving end of the electric push rod is fixedly connected to the slider. A tension roller is rotatably disposed on the adjusting block. A support spring is disposed between the slider and the adjusting block. An electromagnetic button and a contact block are respectively disposed on one side of the slider opposite to the adjusting block. The contact block cooperates with the electromagnetic button to abut against it. The electromagnetic button is electrically connected to the electric push rod.

[0007] Furthermore, each of the two fixed plates has a fixed groove on its opposite side, the electric push rod is fixedly installed on the bottom wall of the fixed groove, and the slider and the adjusting block are slidably connected in the fixed groove.

[0008] Furthermore, bearings are fixedly installed on opposite sides of the two fixed plates, and the end of the tension roller is fixedly inserted into the inner ring of the bearing.

[0009] Furthermore, a limiting groove is provided on the side of the fixing plate, and a limiting component is fixedly installed on the side of the adjusting block. A ball is rotatably provided on one side of the limiting component, and the ball is rotatably connected in the limiting groove.

[0010] Furthermore, each of the fixed plates has two side limiting grooves, and the two limiting grooves are symmetrically opened on the side of the fixed plate and connected to the fixed groove.

[0011] Furthermore, the limiting member has an installation cavity and a sliding opening on its interior and one side, respectively. The sliding opening is connected to the installation cavity, and the ball is rotatably installed in the installation cavity, with part of it passing through the sliding opening and located outside the limiting member.

[0012] Furthermore, limit rings are fixedly sleeved at both ends of the tension roller, and the diameter of the limit rings is larger than the diameter of the tension roller.

[0013] Furthermore, a feeding assembly and a take-up assembly are respectively provided at both ends of the top of the frame. The height of the tension roller is higher than the feeding assembly and the take-up assembly. The feeding assembly includes two fixing members, which are symmetrically installed at one end of the top of the frame. A feed roller is rotatably installed between the two fixing members. The feed roller is used to wind the yarn to be woven. The take-up assembly includes two mounting plates, which are symmetrically installed at the end of the top of the frame away from the fixing members. A take-up roller is rotatably installed between the two mounting plates. A motor is fixedly installed on one side of one of the mounting plates. The drive shaft of the motor is connected to one end of the take-up roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: as the yarn body on the feeding assembly decreases continuously during textile processing, the overlap height on the tension roller increases, causing the support spring to push the adjusting block upward. At the same time, the contact block separates from the electromagnetic button. At this time, the electromagnetic button controls the drive end of the electric push rod to extend and drive the slider upward, causing the support spring to compress again and make the contact block contact the electromagnetic button, thus achieving the effect of adaptive tension adjustment without manual intervention, improving the usage effect.

[0015] Compared with the prior art, the beneficial effects of this utility model are: during the sliding process of the adjusting block, the adjusting block will drive the ball to roll in the limiting groove, which can change the sliding friction of the adjusting block to rolling friction, and avoid the problem that the adjusting block cannot slide normally due to excessive friction.

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a tension control device for a textile machine, including a frame 1, with fixed plates 4 fixedly installed at both the front and rear ends of the top of the frame 1, a slider 7 and an adjusting block 8 slidably arranged inside the fixed plate 4, an electric push rod 6 fixedly installed inside the fixed plate 4, the driving end of the electric push rod 6 being fixedly connected to the slider 7, a tension roller 9 being rotatably arranged on the adjusting block 8, a support spring 10 being arranged between the slider 7 and the adjusting block 8, and an electromagnetic button 12 and a contact block 11 being respectively arranged on one side of the slider 7 opposite to the adjusting block 8, the contact block 11 and the electromagnetic button 12 cooperating and abutting each other, and the electromagnetic button 12 being electrically connected to the electric push rod 6;

[0023] The top of the frame 1 is provided with a feeding assembly 2 and a take-up assembly 3 at both ends. The tension roller 9 is higher than the feeding assembly 2 and the take-up assembly 3. The feeding assembly 2 includes two fixing parts, which are symmetrically installed at one end of the top of the frame 1. A feed roller is rotatably installed between the two fixing parts. The feed roller is used to wind the yarn to be woven. The take-up assembly 3 includes two mounting plates, which are symmetrically installed at the top of the frame 1 away from the fixing parts. A take-up roller is rotatably installed between the two mounting plates. A motor is fixedly installed on one side of one of the mounting plates. The drive shaft of the motor is connected to one end of the take-up roller.

[0024] In practice, one end of the woven thread wound on the feeding assembly 2 is first overlapped with the tension roller 9 and then wrapped around the take-up assembly 3. Since the tension roller 9 is higher than the feeding assembly 2 and the take-up assembly 3, the thread will press down on the tension roller 9 and drive the adjusting block 8 to compress the support spring 10, so that the contact block 11 abuts against the electromagnetic button 12. At this time, the tension of the thread is set to the optimal value. During the weaving and conveying of the thread, as the thread on the feeding assembly 2 decreases, the overlap height on the tension roller 9 will increase, causing the support spring 10 to push the adjusting block 8 upward. At the same time, the contact block 11 separates from the electromagnetic button 12. At this time, the electromagnetic button 12 will send an electrical signal to the electric push rod 6 and cause the drive end of the electric push rod 6 to extend and drive the slider 7 upward, so that the support spring 10 is compressed again and the contact block 11 contacts the electromagnetic button 12. This achieves the effect of adaptive tension adjustment without manual intervention, thus improving the performance.

[0025] See Figure 1-4 Each of the two fixed plates 4 has a fixed groove 5 on one side opposite to the other. The electric push rod 6 is fixedly installed on the bottom wall of the fixed groove 5, and the slider 7 and the adjusting block 8 are slidably connected in the fixed groove 5. This design allows the electric push rod 6 to be easily fixed in the fixed plate 4, and also allows the slider 7 and the adjusting block 8 to be reasonably slidably installed in the fixed plate 4, avoiding motion interference and ensuring normal operation.

[0026] See Figure 1-4 Bearings are fixedly installed on opposite sides of the two fixed plates 4, and the end of the tension roller 9 is fixedly inserted into the inner ring of the bearing. This facilitates the rotational installation of the tension roller 9 on the adjusting block 8 and improves the stability of the tension roller 9 during rotation.

[0027] A limiting groove 13 is provided on the side of the fixed plate 4. A limiting component 14 is fixedly installed on the side of the adjusting block 8. A ball bearing 15 is rotatably provided on one side of the limiting component 14. The ball bearing 15 is rotatably connected in the limiting groove 13. An installation cavity 17 and a sliding opening 16 are respectively provided inside the limiting component 14 and on one side. The sliding opening 16 is connected to the installation cavity 17. The ball bearing 15 is rotatably installed in the installation cavity 17 and partially passes through the sliding opening 16 outside the limiting component 14.

[0028] In specific implementation, based on the above implementation, during the sliding process of the adjusting block 8, the adjusting block 8 will drive the ball 15 to roll in the limiting groove 13, which can change the sliding friction of the adjusting block 8 to rolling friction, so as to avoid the problem that the adjusting block 8 cannot slide normally due to excessive friction.

[0029] See Figure 1-4Each fixed plate 4 has two side limiting grooves 13, and the two limiting grooves 13 are symmetrically opened on the side of the fixed plate 4 and connected to the fixing groove 5. The setting of two limiting grooves 13 can balance the force on both sides of the adjusting block 8, thereby avoiding the problem of the adjusting block 8 tilting during operation.

[0030] Limiting rings 18 are fixedly sleeved at both ends of the tension roller 9. The diameter of the limiting rings 18 is larger than the diameter of the tension roller 9. This limits the thread that overlaps the tension roller 9, preventing the thread from slipping off the side of the tension roller 9.

[0031] Working principle: Before use, all electrical appliances on rack 1 need to be connected to an external power source, or an electrical box needs to be installed on rack 1 in an area that does not obstruct other components. Then, the electrical box is connected to the electrical appliances through a line to supply power to the electrical appliances, thereby ensuring their normal operation. Since connecting the electrical appliances to an external power source or setting up an electrical box for power supply is existing technology and is not a problem that needs to be solved in the background technology of this manual, it will not be explained in detail.

[0032] In use, one end of the woven thread wound on the feeding assembly 2 is first overlapped with the tension roller 9 and then wrapped around the take-up assembly 3. Since the tension roller 9 is higher than the feeding assembly 2 and the take-up assembly 3, the thread will press down on the tension roller 9 and drive the adjusting block 8 to compress the support spring 10, so that the contact block 11 abuts against the electromagnetic button 12. At this time, the tension of the thread is set to the optimal value. During the weaving and conveying of the thread, as the thread on the feeding assembly 2 decreases, the overlap height on the tension roller 9 will increase, causing the support spring 10 to push the adjusting block 8 upward. At the same time, the contact block 11 separates from the electromagnetic button 12. At this time, the electromagnetic button 12 will send an electrical signal to the electric push rod 6 and cause the drive end of the electric push rod 6 to extend and drive the slider 7 upward, so that the support spring 10 is compressed again and the contact block 11 contacts the electromagnetic button 12. This achieves the effect of adaptive tension adjustment without manual intervention, thus improving the performance.

[0033] During the sliding process of the adjusting block 8, the adjusting block 8 will drive the ball 15 to roll in the limiting groove 13, which can change the sliding friction of the adjusting block 8 to rolling friction, thus avoiding the problem that the adjusting block 8 cannot slide normally due to excessive friction.
