Description

Technical Field

[0001] This utility model relates to the field of yarn rack technology, and more specifically, to a yarn rack with a quick yarn changing structure. Background Technology

[0002] A yarn rack is an auxiliary device used in the textile industry. It is usually made of materials such as metal, plastic or wood. It typically consists of a support frame, yarn placement components, and tension adjustment devices. Its overall structural design aims to provide a stable and orderly storage and conveying platform for yarn, so that during the textile production process, the yarn can be smoothly wound from the yarn roll or yarn bobbin according to the process requirements and conveyed to the textile machine for processing, realizing the transformation from yarn to fabric.

[0003] A search revealed that publication number CN119503530A discloses a spinning frame for yarn production, including a connecting frame. The front end of the connecting frame has multiple recesses, each containing a coil-carrying mechanism. The coil-carrying mechanism includes a rotating shaft and a round rod. The two ends of the rotating shaft are rotatably connected to the left and right inner walls of the recesses. A long groove penetrating the round rod is recessed on the side wall of the round rod, and the rotating shaft is positioned within the long groove, allowing it to slide along the length of the groove. A first slot for inserting the round rod is recessed on the inner bottom surface of the recess, and a second slot for inserting the round rod is provided on the inner rear surface of the recess. This spinning frame, through its structural design, allows adjustment of the state of adjacent or multiple round rods according to the coil size, accommodating coils of different diameters and improving the applicability of the spinning frame. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing yarn racks often require manual alignment and positioning of yarn spools when changing yarn. This is difficult to operate and prone to positional deviations during the yarn spool positioning process. In addition, some traditional yarn racks require additional tools to assist workers in changing yarn, such as wrenches, to disassemble and install yarn spool fixing devices. This leads to various errors during the yarn spool replacement process. For some yarn racks that require manual loading and unloading of heavy yarn spools, workers are prone to fatigue and injury during frequent loading and unloading.

[0005] Therefore, a yarn holder with a quick yarn changing structure is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a yarn holder with a quick yarn changing structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a yarn rack with a quick yarn changing structure, comprising a lifting mechanism, a support component, and a limiting component, wherein the lifting mechanism, the support component, and the limiting component are provided, and the support component is installed on the side of the lifting mechanism, and the limiting component is installed above the support component, and the lifting mechanism includes a driving component and a sliding component, and the sliding component is placed below the driving component.

[0008] Preferably, the drive assembly includes a motor, a rotating shaft, and a lead screw, with the rotating shaft mounted below the motor and the lead screw mounted below the rotating shaft.

[0009] Preferably, the sliding assembly includes a nut slider, a groove, and a support leg, wherein the nut slider is placed on the inner wall side of the groove, and the support leg is installed below the groove.

[0010] Preferably, the support assembly includes a bracket plate, a connecting plate, and a connecting column, wherein the connecting plate is installed on the side of the bracket plate, and the connecting column is installed on the side of the connecting plate away from the bracket plate.

[0011] Preferably, the limiting assembly includes a limiting rod, a limiting plate, a fixing rod, and a cylinder, wherein the limiting plate is placed on the outer diameter surface of the limiting rod, the fixing rod is installed below the limiting plate, and the cylinder is installed below the fixing rod.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. Compared with the prior art, this yarn rack with a quick yarn changing structure reminds workers to replace nearly used yarn rolls in a timely manner through a limit plate of the limit component. When the yarn roll on the limit plate is in use, the yarn will be continuously pulled off the yarn roll by the textile machine, resulting in a decrease in weight. The pressure sensor installed inside the limit plate will constantly transmit the pressure signal of the limit plate to the control panel. The control panel will process these signals. When the value of the pressure sensor is lower than a certain range, it will transmit a running command to the cylinder, so that the cylinder will push the limit plate upward along the direction of the limit rod through the fixed rod, allowing the worker to find the nearly used yarn roll in time and replace it in time.

[0014] 2. Compared with the existing technology, this yarn rack with a quick yarn changing structure makes it easier for workers to operate during the yarn roll replacement process by installing a threaded tube at the bottom of the yarn roll. When the yarn roll needs to be replaced, the worker only needs to separate the yarn roll and the limiting plate by twisting, and then reinstall the new yarn roll on the limiting plate to achieve the effect of quick yarn changing.

Detailed Implementation

[0020] 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.

[0021] Example 1

[0022] As attached Figures 1 to 4 The yarn rack shown includes a lifting mechanism 1, a support component 2, and a limiting component 3. The support component 2 is installed on the side of the lifting mechanism 1, and the limiting component 3 is installed above the support component 2. The lifting mechanism 1 includes a driving component 4 and a sliding component 5, and the sliding component 5 is placed below the driving component 4.

[0023] Specifically: When placing the yarn roll onto the yarn rack for use by the textile machine, the worker needs to adjust the position inside the sliding component 5 by adjusting the drive component 4 of the lifting mechanism 1. The support component 2 and the sliding component 5 are connected by threads, so when the sliding component 5 moves vertically, the support component 2 will also move up and down. After the height of the support component 2 is adjusted to a suitable height to supply yarn to the textile machine, the worker needs to connect the yarn roll and the limiting component 3 by threads. After everything is fixed, the textile machine is started. The weight of the yarn roll on the yarn rack will gradually decrease due to the use of yarn by the textile machine. The pressure sensor installed in the limiting component 3 will constantly detect the weight on the limiting plate 16 and send feedback to the control panel. The control panel will process the signal. When the pressure on the limiting plate 16 is lower than a certain threshold, the control panel will control the limiting component 3 to remind the worker to replace the yarn roll above it in time.

[0024] Example 2

[0025] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0026] In a preferred embodiment, the drive assembly 4 includes a motor 6, a rotating shaft 7, and a lead screw 8. The rotating shaft 7 is welded to the bottom of the motor 6, and the lead screw 8 is welded to the bottom of the rotating shaft 7. When the drive assembly 4 is running, the motor 6 drives the lead screw 8 to rotate through the rotating shaft 7, and the lead screw 8 drives the parts inside the sliding assembly 5 to move vertically while rotating.

[0027] In a preferred embodiment, the sliding assembly 5 includes a nut slider 9, a slide groove 10, and a support leg 11. The nut slider 9 is placed on the inner side of the slide groove 10, and the slide groove 10 and the nut slider 9 are slidably connected. The support leg 11 is bolted to the bottom of the slide groove 10. When the drive assembly 4 rotates, it will drive the nut slider 9 to slide vertically in the slide groove 10, and the support leg 11 will provide support for the slide groove 10.

[0028] In a preferred embodiment, the support assembly 2 includes a bracket plate 12, a connecting plate 13, and a connecting column 14. The connecting plate 13 is bolted to the side of the bracket plate 12, and the connecting column 14 is bolted to the side of the connecting plate 13 away from the bracket plate 12. When the parts inside the sliding assembly 5 move vertically, the connecting column 14 connected to it also moves vertically. At this time, the connecting column 14 will drive the bracket plate 12 to move vertically through the connecting plate 13.

[0029] In a preferred embodiment, the limiting assembly 3 includes a limiting rod 15, a limiting plate 16, a fixing rod 17, and a cylinder 18. The limiting plate 16 is placed on the outer diameter surface of the limiting rod 15. The fixing rod 17 is bolted to the bottom of the limiting plate 16, and the cylinder 18 is welded to the bottom of the fixing rod 17. The pressure sensor in the limiting plate 16 is a WIKA F2221. When pressure is applied to the object being measured, the force is transmitted directly to the screws on both sides of the sensor body. The sensitive element inside the sensor deforms proportionally to the external force under the action of the external force. This deformation causes a change in the resistance value of the sensitive element. Then, the electronic circuit inside the sensor captures the resistance value. The pressure changes are measured and converted into electrical signal changes using circuits such as a Wheatstone bridge. This signal is then further amplified, processed, and calibrated to output a standard signal corresponding to the measured pressure. The upper end of the limit plate 16 has a threaded interface for threaded connection with the yarn roll. A pressure sensor is installed in the middle of the limit plate 16 to detect the weight of the yarn roll. When the weight of the yarn roll decreases to a certain value, the control panel controls the cylinder 18 to operate. The cylinder 18 drives the limit plate 16 upward via the fixed rod 17, and the yarn roll mounted on the limit plate 16 also moves upward along the limit rod 15, allowing workers to promptly identify and replace yarn rolls that are about to run out.

[0030] The working process of this utility model is as follows: First, when the yarn roll is to be placed on the yarn rack for use by the textile machine, the worker needs to adjust the position inside the sliding component 5 by adjusting the drive component 4 of the lifting mechanism 1. When the drive component 4 is running, the motor 6 will drive the lead screw 8 to rotate through the rotating shaft 7. While the lead screw 8 is rotating, it will drive the nut slider 9 to slide vertically in the slide groove 10. The support leg 11 will provide support for the slide groove 10. When the nut slider 9 moves vertically, the connecting column 14 connected to it will also move vertically. At this time, the connecting column 14 will drive the support plate 12 to move vertically through the connecting plate 13, thereby adjusting the height of the support component 2. When the height of the support component 2 is adjusted to a suitable height for supplying yarn to the textile machine, the worker needs to place the yarn roll and the limiting component... 3. After threaded connection and all fixing is completed, start the textile machine. As time goes by, the weight of the yarn rolls on the yarn rack will gradually decrease due to the use of yarn by the textile machine. The pressure sensor installed in the limit component 3 will constantly detect the weight on the limit plate 16 and send feedback to the control panel. The control panel will process the signal. When the pressure on the limit plate 16 is lower than a certain threshold, the control panel will control the cylinder 18 of the limit component 3 to operate. The cylinder 18 will drive the limit plate 16 to move upward through the fixed rod 17. The yarn rolls installed on the limit plate 16 will also move upward along the limit rod 15, so that the workers can find the yarn rolls that are about to run out in time and replace them in time. The above is the working principle of this yarn rack with a quick yarn changing structure.
