Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, specifically to an adjustable yarn twist count adjustment device for textile machinery. Background Technology

[0002] Yarn twisting is a textile process that increases the density and physical and mechanical properties of yarn by twisting. In simple terms, it involves twisting multiple yarns together to form a single strand, thereby improving the overall strength, feel, elasticity, and density of the yarn. Twisting not only increases the density of the yarn but also changes its package shape and linear density to meet the requirements of post-processing and use.

[0003] Most existing yarn twisting equipment on the market can only perform twisting operations with a fixed number of yarns. Different twisting guide devices are used to perform twisting operations according to the actual product requirements. It is difficult to change the maximum number of yarns twisted on the same equipment according to user needs. This results in a certain room for improvement in the adaptability of yarn twisting operations on a single equipment. Moreover, the yarn twisting selection and guiding structure of most existing yarn twisting equipment is just a channel for yarn movement. The yarn moving in the channel is only affected by tension. During the twisting process, adjacent yarns are prone to entanglement and jamming, which will affect the surface smoothness of the twisted yarn. In order to solve the above problems, this invention provides an adjustable yarn twisting number adjustment device for textile machinery. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable yarn twisting head adjustment device for textile machinery. It has the advantages of being able to freely adjust the number of yarn twists according to the user's actual needs, and also allowing the yarn to receive additional tension before twisting. This solves the problem that the total number of twists in existing yarn twisting devices is mostly inconvenient to increase according to actual needs, resulting in a narrow application space for the overall device.

An arc-shaped hole is provided on the right side of the symmetrical plate for the left end of the arc-shaped rod to pass through and slide.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 5 The present invention provides a technical solution: an adjustable yarn twist count adjustment device for textile machinery, including a steel structure bracket 1, a support panel 2 fixedly installed on the front of the steel structure bracket 1, a wire assembly 300 installed on the top of the support panel 2, and an installation assembly 400 installed on the outside of the wire assembly 300.

[0031] In the above embodiment, the yarn can be tensioned by the conductor assembly 300, thereby reducing the possibility of tangling and jamming, which helps to protect the surface smoothness of the finished product after twisting and improves the quality of the product to a certain extent. By using the installation component 400, the actual number of yarn twists can be increased according to the user's needs, which increases the actual applicable space of the yarn twist number adjustment device and makes it easy for the user to control and operate it. Thus, through the modular structure, this yarn twist number adjustment device has the advantages of being able to freely adjust the number of yarn twists according to the user's actual needs and also allowing the yarn to be subjected to additional tension before twisting.

[0032] In this embodiment, the conductor assembly 300 is a structure used to guide and elastically support the yarn.

[0033] like Figure 2 , Figure 3 and Figure 5 As shown, the wire assembly 300 includes several wire plates 301 mounted on the top of the support panel 2. Several wire holes 302 are formed on the left side of each wire plate 301. Two protective plates 303 are fixed inside the wire holes 302. A connecting plate 304 abuts against the left side of the wire plate 301. A fixing plate 305 is fixed to the left side of the connecting plate 304. Four trapezoidal blocks 306 are fixed to the right side of the connecting plate 304. The top of the wire plate 301 has four trapezoidal slots 307 for the corresponding four trapezoidal blocks 306 to be inserted into and slide. The top of the fixing plate 305 is fixed... There are several rotating plates 308. On the opposite side of two corresponding rotating plates 308, a movable plate 309 is rotatably connected via a rotating shaft. On the opposite side of two corresponding movable plates 309, a support roller 310 is rotatably connected via a rotating shaft. On the opposite side of two corresponding movable plates 309, an extension plate 311 is fixed. Two arc-shaped rods 312 are fixed at the bottom of the extension plate 311. A limit plate 313 is fixed at the left end of the arc-shaped rods 312. Several symmetrical plates 314 are fixed at the top of the fixed plate 305. Two springs 315 are fixed at the bottom of the extension plate 311.

[0034] It should be noted that the wire hole 302 is circular, and there are five wire holes 302 on each wire plate 301. The protective plate 303 is an arc-shaped plate, and two corresponding protective plates 303 are symmetrically distributed on the inner side of the wire hole 302, so that the yarn can be normally fed inside the wire hole 302. Under the action of the protective plate 303, the friction between the yarn and the inner wall of the wire hole 302 can be reduced, thus playing a protective role. The left side of the trapezoidal groove 307 is open, and the bottom of the trapezoidal groove 307 is closed. Through the sliding limit cooperation between the trapezoidal block 306 and the trapezoidal groove 307, the connecting plate 304 can be stably positioned. Threaded holes can also be opened on the wire plate 301, and the connecting plate 304 can be further positioned by using hexagonal socket head cap screws.

[0035] In addition, each pair of rotating plates 308 forms a group, and each fixed plate 305 has five sets of rotating plates 308 on its top, which correspond to the positions of the five corresponding wire holes 302. The support roller 310 is located on the left side of the corresponding wire hole 302, so as to support the yarn output from the wire hole 302 through the support roller 310. The number of symmetrical plates 314 is equal to the number of arc rods 312. An arc hole is opened on the right side of the symmetrical plate 314 for the left end of the arc rod 312 to pass through and slide. The center of the arc rod 312 is the same as the center of the rotating shaft on the rotating plate 308, so that the arc rod 312 can be driven by the extension plate 311 to rotate together with the rotating shaft on the rotating plate 308 and the movable plate 309. Under the action of the arc hole, the symmetrical plate 314 and the corresponding arc rod 312 can be slidably connected.

[0036] Meanwhile, the spring 315 is located on the outside of the corresponding arc-shaped rod 312, and the left end of the spring 315 is fixedly connected to the right side of the corresponding symmetrical plate 314, so that the extension plate 311 can drive the spring 315 to compress stably during the movement.

[0037] In this embodiment, the mounting component 400 is a structure used to increase the number of twisted threads.

[0038] like Figure 1 , Figure 2 and Figure 4As shown, the mounting assembly 400 includes several plug-in blocks 401 fixed to the bottom of the conductor plate 301. Four plug-in slots 402 are provided on the top of both the support panel 2 and the conductor plate 301. Two shielding plates 403 are provided on the front of the conductor plate 301. Several connecting holes 404 are provided on the top of the shielding plates 403. Several wire-passing holes 405 are provided on both the top and bottom of the conductor plate 301. Positioning plates 406 are fixed on both the front and back of the shielding plates 403. A handle 407 is fixedly installed on the front of the front positioning plate 406. A placement plate 408 is fixed on the top of the back of the conductor plate 301. A pin 409 is passed through the top of the placement plate 408. Several L-shaped blocks 410 are fixed on the bottom right side of all conductor plates 301 except the first one at the bottom. Several mating blocks 411 are fixed on the top right side of the conductor plate 301. Connectors 412 pass through the L-shaped blocks 410 and their corresponding mating blocks 411 on opposite sides.

[0039] It should be noted that each conductor plate 301 has four fixed plug blocks 401 at its bottom. The four plug blocks 401 can be inserted into the inner side of the corresponding four plug slots 402 to facilitate the initial positioning of the conductor plate 301. The two corresponding baffles 403 are located at the top and bottom of the conductor hole 302, respectively. The inside of the conductor hole 302 is connected to the inside of the corresponding two thread holes 405. The inside of the connecting hole 404 can be connected to the inside of the corresponding thread hole 405, so that the yarn can enter the inside of the conductor hole 302 through the top thread hole 405 and the corresponding connecting hole 404.

[0040] In addition, the top of the baffle plate 403 is provided with a socket for the corresponding pin 409 to be inserted. The pin 409 can be inserted into the two corresponding sockets at the same time. When the back of the rear positioning plate 406 and the back of the wire plate 301 abut, the interior of the connecting hole 404 and the wire hole 405 are in a connected state. When the front of the front positioning plate 406 and the front of the wire plate 301 abut, the two corresponding sockets can be used for the pin 409 to be inserted at the same time, so as to achieve the positioning effect of the baffle plate 403. The outer side of the bottom first wire plate 301 is connected to the top of the support panel 2 by bolts, which facilitates disassembly and installation.

[0041] Meanwhile, the L-shaped block 410 is located on the back side of the corresponding mating block 411. The connector 412 includes a screw and a nut. The screw passes through the back side of the corresponding L-shaped block 410 and the mating block 411, and the nut is threaded on the outside of the screw for positioning and fixing. Thus, the L-shaped block 410 and the mating block 411 can be connected and fixed by the cooperation of the screw and the nut.

[0042] The working principle of the above embodiments is as follows:

[0043] (1) When the yarn is twisted in the textile work, the yarn is passed through the inside of the wire hole 302 and then connected to the twisting equipment to perform the twisting work. During the movement of the yarn, the support roller 310 can play a certain rolling support role. When the downward pressure is too large, it can drive the extension plate 311 and the arc rod 312 to move, thereby compressing the corresponding spring 315. Under the elastic deformation of the spring 315, the support roller 310 can play an elastic support role for the yarn, thereby applying a certain pressure to it so that it can be tensioned, reducing the possibility of tangling and jamming, thus protecting the surface smoothness of the twisted yarn product.

[0044] (2) When adjusting the number of twisted threads according to actual product requirements, remove the added guide plate 301, insert the corresponding plug block 401 into the inside of the plug slot 402, and move the L-shaped block 410 to the back side of the corresponding docking block 411. Connect and fix it through the connector 412 to complete the installation of the guide plate 301. Remove the pin 409, slide the two corresponding baffles 403 to connect the inside of the connecting hole 404 with the inside of the corresponding threading hole 405. The required yarn can then be moved through the top threading hole 405 to the inside of the corresponding guide hole 302 at the same time, avoiding the tediousness of threading one by one, simplifying the steps and difficulty of threading the yarn, and also allowing the yarn to pass through the corresponding two The threading hole 405 is moved inside the threading hole 302 in the adjacent guide plate 301, so that even if the number of guide plates 301 is increased, the addition of yarn can still be easily carried out. After the movement is completed, push the handle 407 and insert the pin 409 between the corresponding two baffle plates 403 to complete the movement and positioning of the baffle plates 403. At this time, the top and bottom of the threading hole 302 are blocked by the corresponding two baffle plates 403 to prevent the yarn from moving out. Move the trapezoidal block 306 from top to bottom to the inside of the corresponding trapezoidal groove 307 so that the support roller 310 can move to the outside of the corresponding threading hole 302. Then the yarn and the twisting equipment can be connected and the twisting work can be carried out normally.

[0045] Compared with existing technologies, this adjustable yarn twist count adjustment device for textile machinery, through the cooperation between the guide wire hole 302 and the support roller 310, can provide a certain rolling support for the yarn. Furthermore, through the elastic restoring force under the elastic deformation of the spring 315, the support roller 310 can provide a certain elastic tension to the yarn, thereby reducing the possibility of tangling and jamming. This helps protect the surface smoothness of the finished product after twisting, improving product quality to a certain extent. The combination of the L-shaped block 410, the connecting block 411, and the connector 412 allows for easy addition of the guide wire plate 301, enabling the adjustment of the actual yarn twist count according to user needs. The addition of this feature expands the practical application space of the yarn twisting number adjustment device. Furthermore, the movable baffle 403 allows the yarn to easily enter the guide wire hole 302, and it can freely move and adjust within multiple guide wire holes 302 in the longitudinal direction, facilitating user control and operation. Through its modular structure, this yarn twisting number adjustment device allows for free adjustment of the yarn twisting number according to the user's actual needs, and also provides additional tension to the yarn before twisting. This solves the problem that existing yarn twisting devices often have a limited application space due to the inconvenience of increasing the total number of twists according to actual needs.
