AI Technical Summary
In existing tension control devices for cotton yarn twisting, the lack of support at one end of the tension roller leads to wear and skewness, affecting the stability of tension adjustment.
The structure employs a limiting wheel and bonding component. The limiting wheel rolls on the outer wall of the machine casing to support the displacement component, while the intermediate plate slides within the sliding opening. Together with the telescopic rod and bonding component, it limits the cotton yarn and reduces friction, thereby achieving stable up-and-down displacement of the tension roller and tension adjustment.
This effectively prevents tension roller skew, ensures the stability of cotton yarn tension adjustment, reduces friction damage, and improves the long-term operational reliability of the device.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of cotton yarn processing technology, specifically to a tension adjustment device for cotton yarn twisting. Background Technology
[0002] Twisting is a process that uses rotational motion to twist the drafted cotton yarn to fix the longitudinal connection between the fibers. In order to better control the performance of the cotton yarn during twisting, a corresponding tension control device is needed to control the tension of the cotton yarn during processing.
[0003] The prior art patent document CN221918397U discloses a tension control device for cotton yarn twisting. This device uses a motor to drive a screw to rotate, thereby moving a tension roller up and down to apply more or less pressure to the cotton yarn, thus adjusting the tension of the cotton yarn to meet different processing needs and improve the effectiveness of the device. Although this device has many advantages, it still has the following problems: When the tension roller is moved up and down by the motor driving the screw, the tension roller is only limited by the moving plates at both ends, and the screw is only set at one end of the tension roller. During long-term operation, the moving plate away from the screw receives less support and is subjected to the reaction force when adjusting the tension of the cotton yarn. Wear of the moving plate causes the end of the tension roller not controlled by the screw to easily tilt downward. Therefore, in the long-term use of the above device, the tension roller is prone to tilting downward at one end, affecting the normal tension adjustment of the cotton yarn. To address this, we propose a tension adjustment device for cotton yarn twisting. Utility Model Content
[0004] The purpose of this invention is to provide a tension adjustment device for twisting cotton yarn, so as to solve the problem mentioned in the background art that the tension roller with insufficient support is prone to wear and sagging at one end, thus affecting the tension adjustment of cotton yarn.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tension adjusting device for cotton yarn twisting, comprising a housing, a sliding opening on the right side wall of the housing, a limiting rod inside the sliding opening, a limiting component on the side wall of the sliding opening, a limiting wheel inside the limiting component that cooperates with the housing, an intermediate plate fixedly connected to the side wall of the limiting component that cooperates with the limiting rod, a displacement component fixedly connected to the side wall of the intermediate plate that cooperates with the inside of the housing, a plurality of telescopic columns on the top of the displacement component, a support plate fixedly connected to the bottom of the displacement component, a roller on the side wall of the support plate, a conveying roller inside the housing, a conveying motor fixedly connected to the housing at the power input end of the conveying roller, and the conveying motor being electrically connected to a control box.
[0006] Preferably, a mounting plate is fixedly connected to the side wall of the displacement member, and a telescopic rod is provided on the side wall of the mounting plate.
[0007] Preferably, the power output end of the telescopic rod is provided with a limit frame, and the side wall of the limit frame has a limit post fixed to the mounting plate.
[0008] Preferably, the bottom of the limiting frame is provided with a fitting component, and the side wall of the fitting component is embedded with a plurality of balls.
[0009] Preferably, the bonding element is fitted to the outer wall of the roller, and the bonding element has an arc-shaped structure.
[0010] Preferably, the front side wall of the housing has a mating opening, and the control box is fixed to the outer wall of the housing.
[0011] Preferably, a fastening disc is fixed to the top of the telescopic column, and a support frame is provided on the side wall of the telescopic column.
[0012] Preferably, the fastening disc is fixed to the top of the housing, and the bottom of the housing is provided with support legs.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. When the telescopic column extends, the displacement component moves downward. At this time, the limiting component, in conjunction with the sliding port, slides along the side wall of the machine housing. While the limiting component slides, the limiting wheel rolls against the outer wall of the machine housing. Simultaneously, the middle plate slides inside the sliding port. This allows the displacement component to move up and down stably, thanks to the rolling of the limiting wheel and the limiting effect of the middle plate in conjunction with the sliding port. Moreover, the rolling of the limiting wheel, in conjunction with the limiting component, supports both ends of the displacement component during displacement, preventing uneven heights at both ends of the roller and thus avoiding skew. This allows the roller to stably adjust the tension of the cotton yarn, which is beneficial for the long-term stable operation of the tension adjustment device for cotton yarn twisting.
[0015] 2. In this invention, when the cotton yarn is used in conjunction with the conveyor roller and the drum for tension adjustment, the cotton yarn is located between the two bonding parts of the drum. At this time, the extension and retraction of the telescopic rod can cause the limiting frame to drive the bonding parts to slide on the outer wall of the drum in conjunction with the limiting post. This makes the bonding parts located on both sides of the cotton yarn on the outer wall of the drum, which can limit the cotton yarn during tension adjustment and reduce the trouble of the cotton yarn being skewed during tension adjustment. At the same time, the ball bearings located on the side wall of the bonding parts can roll with the cotton yarn when the cotton yarn is guided by the bonding parts, thereby reducing friction and reducing the wear of the bonding parts on the cotton yarn.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the 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.
[0023] Example
[0024] Please see Figures 1-5The diagram illustrates a tension adjusting device for cotton yarn twisting, comprising a housing 100. A sliding opening 120 is provided on the right side wall of the housing 100. A limit rod 121 is bolted to the inside of the sliding opening 120. The limit rod 121 is made of a common, smooth-surfaced steel pipe, and its outer wall is coated with common lubricant. A limit component 130 slidably engages with the side wall of the sliding opening 120. A limit wheel 131, which is a common stainless steel wheel, is provided inside the limit component 130 and engages with the housing 100. The side wall of the limiting member 130 is bolted to an intermediate plate 132 that fits with the limiting rod 121. The thickness of the intermediate plate 132 is the same as the thickness of the right side wall of the housing 100. The side wall of the intermediate plate 132 is bolted to a displacement member 140 that fits inside the housing 100. The top of the displacement member 140 is provided with multiple telescopic columns 124. The telescopic columns 124 use commercially available telescopic cylinders. The telescopic columns 124 are connected to an external air pump as the source of gas drive. This is existing technology. The displacement member 140... A support plate 141 is bolted to the bottom. A roller 142 is mounted on the side wall of the support plate 141. The roller 142 is a common smooth stainless steel cylinder. A conveyor roller 110 is installed inside the machine housing 100. When adjusting the tension of the cotton yarn, the cotton yarn is fed into the machine housing 100 through the mating port 101, then mats between the front conveyor rollers 110, then between the bottom of the roller 142, and finally between the rear conveyor rollers 110 before exiting through the mating port 101 on the rear side of the machine housing 100. The power input end of 110 is equipped with a conveyor motor 111 that is bolted to the housing 100. The conveyor motor 111 is a common motor on the market. The conveyor motor 111 is electrically connected to the control box 102. The control box 102 is equipped with a common switch for controlling the conveyor motor 111. At the same time, the control box 102 is equipped with a common microcontroller for the air pump that is electrically connected to the telescopic column 124. By pre-setting the microcontroller, the two telescopic columns 124 can be extended and retracted simultaneously, which is the existing technology.
[0025] Specifically, the side wall of the displacement component 140 is fixed to the mounting plate 150 by bolts. The side wall of the mounting plate 150 is provided with a telescopic rod 151. The telescopic column 124 is a common electric push rod with an external reversing switch.
[0026] Furthermore, a limit frame 160 is provided at the power output end of the telescopic rod 151, and a limit post 152 is bolted to the mounting plate 150 through the side wall of the limit frame 160.
[0027] Furthermore, the bottom of the limiting frame 160 is provided with a fitting part 161, and multiple balls 162 are embedded in the side wall of the fitting part 161. The limiting frame 160 and the fitting part 161 are made of aluminum alloy commonly available on the market. The limiting frame 160 is slidably fitted to the side wall of the displacement part 140.
[0028] In some embodiments, small rollers made of common stainless steel can be used instead of balls 162. The small rollers are also embedded in the sidewall of the bonding member 161, and the rotation axis of the small rollers points to the center of the inner arc of the bonding member 161, so that the small rollers can be rolled under force when the cotton yarn is bonded to the sidewall of the bonding member 161 to reduce friction.
[0029] Furthermore, the bonding component 161 is fitted to the outer wall of the roller 142, and the bonding component 161 has an arc-shaped structure.
[0030] Furthermore, the front and rear side walls of the housing 100 are provided with mating openings 101, and the control box 102 is fixed to the outer wall of the housing 100 by bolts.
[0031] In some embodiments, an openable operating door may be provided on the left side wall of the housing 100 to facilitate observation of the internal structural operation status of the housing 100, and also to facilitate timely inspection and maintenance of the internal structure of the housing 100.
[0032] It is worth noting that the top of the telescopic column 124 is fixed with a fastening plate 122 by bolts, and the side wall of the telescopic column 124 is provided with a support frame 123 fixed with bolts to the inner wall of the housing 100.
[0033] It is worth noting that the fastening plate 122 is fixed to the top of the housing 100 by bolts, and the bottom of the housing 100 is provided with support legs.
[0034] In addition, all the electrical components and equipment mentioned above use external power sources. The circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.
[0035] Working principle: When the telescopic column 124 extends, the displacement member 140 moves downward. At this time, the limiting member 130, in conjunction with the sliding opening 120, slides along the side wall of the housing 100. While the limiting member 130 slides, the limiting wheel 131 rolls against the outer wall of the housing 100. Simultaneously, the intermediate plate 132 slides inside the sliding opening 120. This allows the displacement member 140 to move up and down stably, thanks to the rolling of the limiting wheel 131 and the limiting effect of the intermediate plate 132 and the sliding opening 120. Furthermore, the rolling of the limiting wheel 131, in conjunction with the limiting member 130, supports both ends of the displacement member 140 during displacement, preventing unevenness in the height of the two ends of the roller 142 and thus ensuring the stability of the roller 142. Adjusting the tension of cotton yarn is beneficial for the long-term stable operation of the tension adjustment device for twisting cotton yarn. When the cotton yarn is used for tension adjustment in conjunction with the conveyor roller 110 and the drum 142, the cotton yarn is located between the two bonding parts 161 of the drum 142. At this time, the extension and retraction of the telescopic rod 151 can cause the limiting frame 160 to drive the bonding parts 161 to slide on the outer wall of the drum 142 in conjunction with the limiting post 152. This allows the bonding parts 161 to be located on both sides of the cotton yarn on the outer wall of the drum 142, which can limit the cotton yarn during tension adjustment and reduce the trouble of the cotton yarn deviating during tension adjustment. At the same time, the ball bearings 162 located on the side wall of the bonding parts 161 can roll with the cotton yarn when guided by the bonding parts 161, thereby reducing friction and reducing the wear of the bonding parts 161 on the cotton yarn.
