Description

Technical Field

[0001] The utility model relates to the technical field of broken - wire clamping of circular knitting machines, and specifically relates to a broken - wire clamping device for circular knitting machines. Background Technique

[0002] The full name of a circular knitting machine is a knitting circular knitting machine. During the process of using a knitting circular knitting machine for weaving, various reasons may cause the knitting thread to break. After the broken knitting thread rebounds due to tension, in order to prevent the knitting thread from rebounding and detaching from the circular knitting machine, a broken - wire clamping device for circular knitting machines is needed;

[0003] Existing ones, with the publication number of CN220520769U, disclose a broken - wire clamping device for circular knitting machines, which includes a mounting base. An installation frame is arranged on the upper side of the mounting base. A hinge seat is arranged downward on the installation frame. A rocker is hinged on the hinge seat. A first wire guide hook is arranged on the lower side of one end of the rocker. A counterweight iron block is arranged on the lower side of the other end of the rocker. The distance from the end of the rocker where the first wire guide hook is arranged to the hinge seat is greater than the distance from the end of the rocker where the counterweight iron block is arranged to the hinge seat. An electromagnet is arranged on the mounting base directly below the counterweight iron block. A second wire guide hook is arranged on the mounting base at one end of the rocker, and a third wire guide hook is arranged on the mounting base at the other end of the rocker. The utility model can clamp the yarn in time when the yarn breaks;

[0004] However, the existing broken - wire clamping device for circular knitting machines only sets up one line of defense for clamping the broken wire. In actual use, the resilience of the broken knitting thread varies due to the elasticity of the knitting thread itself. When the broken knitting thread rebounds too fast, it is easy to cause the situation of clamping failure, and the clamping effect is not ideal enough. Summary of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] The purpose of the utility model is to provide a broken - wire clamping device for circular knitting machines to solve the problem that the existing broken - wire clamping device for circular knitting machines only sets up one line of defense for clamping the broken wire. In actual use, the resilience of the broken knitting thread varies due to the elasticity of the knitting thread itself. When the broken knitting thread rebounds too fast, it is easy to cause the situation of clamping failure, and the clamping effect is not ideal enough as mentioned in the above background technique.

[0007] (2) Technical Solutions

[0008] To achieve the above object, the present utility model provides the following technical solutions: A wire-breaking clamping device for a circular knitting machine, including a strengthening mechanism: a top plate and a second magnetic block, a clamping mechanism: a bottom plate, a U-shaped frame, a magnetic strip, a positioning rod, a gravity block and a first magnetic block, a wire guiding mechanism: a support rod, a mounting plate, a knitting wire guiding ring, an upper wire guiding ring, a lower wire guiding ring and a knitting wire guiding out ring. The top plate is fixedly installed at the top end of the support rod, and the second magnetic block is fixedly installed at the bottom end of the top plate and magnetically adsorbed with the magnetic strip.

[0009] Preferably, the U-shaped frame is fixedly installed at the top end of the bottom plate. By defining the position of the U-shaped frame through the bottom plate, it is convenient to fix the bottom plate on the winding arm of the circular knitting machine and fix the U-shaped frame for installation.

[0010] Preferably, the magnetic strip is movably installed at the inner end of the U-shaped frame. The positioning rod is fixedly installed at the outer end of the magnetic strip and penetrates through the U-shaped frame. The positioning rods are symmetrically distributed. By defining the position of the magnetic strip through the U-shaped frame and the U-shaped frame and the magnetic strip defining the position of the positioning rod, it is convenient for the positioning rod to position the magnetic strip in the U-shaped frame and enable the magnetic strip to perform a lever movement in the U-shaped frame.

[0011] Preferably, the gravity block is fixedly installed on the left side of the top end of the magnetic strip, and the first magnetic block is fixedly installed at the top end of the bottom plate and magnetically adsorbed with the magnetic strip. By defining the position of the gravity block through the magnetic strip and the bottom plate and the magnetic strip defining the position of the first magnetic block, it is convenient to fix the gravity block to increase the weight of the left end of the magnetic strip. Thus, when the wire breaks, the magnetic strip is no longer supported by the tensile force of the knitting wire, causing the left end of the magnetic strip to tilt downward and adsorb on the first magnetic block to clamp the broken knitting wire.

[0012] Preferably, the support rod is fixedly installed at the top end of the bottom plate. The support rods are symmetrically distributed. The mounting plate is fixedly installed at the inner end of the right support rod. By defining the position of the support rod through the bottom plate and the support rod defining the position of the mounting plate, it is convenient to fix the support rod for supporting and fix the mounting plate for installation.

[0013] Preferably, the knitting wire guiding ring is fixedly installed at the top end of the mounting plate, and the upper wire guiding rings are fixedly installed at the top end of the magnetic strip. There are several upper wire guiding rings. By defining the position of the knitting wire guiding ring through the mounting plate and the magnetic strip defining the position of the upper wire guiding rings, it is convenient to thread the knitting wire through the knitting wire guiding ring and sequentially through multiple upper wire guiding rings to guide the knitting wire.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. The broken wire clamping device for the circular knitting machine is equipped with a strengthening mechanism. The position of the top plate is limited by the support rod, and the positions of the top plate and the magnetic strip limit the position of the second magnetic attraction block, which is convenient for fixing the top plate to fix the second magnetic attraction block. Thus, when the wire is broken, the right end of the magnetic strip tilts upward and adsorbs on the second magnetic attraction block to clamp the broken wire, using the second line of defense to strengthen the clamping effect and prevent the first line of defense from failing to clamp due to the too-fast rebound of the broken wire.

[0016] 2. The broken wire clamping device for the circular knitting machine is equipped with a clamping mechanism. The position of the U-shaped frame is limited by the bottom plate, which is convenient for fixing the bottom plate on the winding arm of the circular knitting machine and fixing the U-shaped frame for installation. The position of the magnetic strip is limited by the U-shaped frame, and the positions of the magnetic strip and the U-shaped frame limit the position of the positioning rod, which is convenient for the positioning rod to position the magnetic strip in the U-shaped frame and enable the magnetic strip to perform a lever movement in the U-shaped frame. The position of the gravity block is limited by the magnetic strip, and the positions of the bottom plate and the magnetic strip limit the position of the first magnetic attraction block, which is convenient for fixing the gravity block to increase the weight of the left end of the magnetic strip. Thus, when the wire is broken, the magnetic strip is no longer supported by the tensile force of the knitting thread, causing the left end of the magnetic strip to tilt downward and adsorb on the first magnetic attraction block to clamp the broken knitting thread.

[0017] 3. The broken wire clamping device for the circular knitting machine is equipped with a wire guiding mechanism. The position of the support rod is limited by the bottom plate, and the position of the mounting plate is limited by the support rod, which is convenient for fixing the support rod for support and fixing the mounting plate for installation. The position of the knitting thread guiding ring is limited by the mounting plate, and the position of the upper wire guiding ring is limited by the magnetic strip, which is convenient for threading the knitting thread into the knitting thread guiding ring and then successively threading it through multiple upper wire guiding rings to guide the knitting thread. The position of the lower wire guiding ring is limited by the magnetic strip, and the position of the knitting thread outlet ring is limited by the mounting plate, which is convenient for threading the knitting thread that has passed through the upper wire guiding rings through multiple lower wire guiding rings in sequence and then leading the knitting thread out from the knitting thread outlet ring, enabling the knitting thread to provide tensile support for the magnetic strip and thus maintaining the horizontal state of the magnetic strip.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 - 4 , the present invention provides a technical solution: a broken wire clamping device for a circular knitting machine, including a reinforcing mechanism 1: a top plate 101 and a second magnetic attracting block 102, a clamping mechanism 2: a bottom plate 201, a U-shaped frame 202, a magnetic strip 203, a positioning rod 204, a gravity block 205 and a first magnetic attracting block 206, a wire guiding mechanism 3: a support rod 301, a mounting plate 302, a thread guiding-in ring 303, an upper wire guiding ring 304, a lower wire guiding ring 305 and a thread guiding-out ring 306. The top plate 101 is fixedly installed at the top end of the support rod 301, and the second magnetic attracting block 102 is fixedly installed at the bottom end of the top plate 101 and magnetically adsorbs with the magnetic strip 203;

[0025] The U-shaped frame 202 is fixedly installed at the top of the bottom plate 201. The position of the U-shaped frame 202 is defined by the bottom plate 201, which facilitates fixing the bottom plate 201 on the winding arm of the circular knitting machine and fixing the U-shaped frame 202 for installation. The magnetic strip 203 is movably installed at the inner end of the U-shaped frame 202. The positioning rod 204 is fixedly installed at the outer end of the magnetic strip 203 and penetrates through the U-shaped frame 202. The positioning rods 204 are symmetrically distributed. The position of the magnetic strip 203 is defined by the U-shaped frame 202, and the position of the positioning rod 204 is defined by the magnetic strip 203 and the U-shaped frame 202, which facilitates the positioning rod 204 to position the magnetic strip 203 in the U-shaped frame 202 and enables the magnetic strip 203 to perform a lever movement in the U-shaped frame 202. The gravity block 205 is fixedly installed on the left side of the top of the magnetic strip 203. The first magnetic attraction block 206 is fixedly installed at the top of the bottom plate 201 and magnetically adsorbs with the magnetic strip 203. The position of the gravity block 205 is defined by the magnetic strip 203, and the position of the first magnetic attraction block 206 is defined by the bottom plate 201 and the magnetic strip 203, which facilitates fixing the gravity block 205 to increase the weight of the left end of the magnetic strip 203. Thus, when the thread breaks, the magnetic strip 203 is no longer supported by the tensile force of the knitting thread, causing the left end of the magnetic strip 203 to tilt downward and adsorb on the first magnetic attraction block 206 to clamp the broken knitting thread.

[0026] The support rods 301 are fixedly installed at the top of the bottom plate 201. The support rods 301 are symmetrically distributed. The mounting plate 302 is fixedly installed at the inner end of the right support rod 301. The position of the support rods 301 is defined by the bottom plate 201, and the position of the mounting plate 302 is defined by the support rods 301, which facilitates fixing the support rods 301 for support and fixing the mounting plate 302 for installation. The knitting thread guiding ring 303 is fixedly installed at the top of the mounting plate 302. The upper wire guiding rings 304 are fixedly installed at the top of the magnetic strip 203. There are several upper wire guiding rings 304. The position of the knitting thread guiding ring 303 is defined by the mounting plate 302, and the position of the upper wire guiding rings 304 is defined by the magnetic strip 203, which facilitates threading the knitting thread through the knitting thread guiding ring 303 and sequentially through multiple upper wire guiding rings 304 to guide the knitting thread. The lower wire guiding rings 305 are fixedly installed at the bottom of the magnetic strip 203. There are several lower wire guiding rings 305. The knitting thread outlet ring 306 is fixedly installed at the bottom of the mounting plate 302. The position of the lower wire guiding rings 305 is defined by the magnetic strip 203, and the position of the knitting thread outlet ring 306 is defined by the mounting plate 302, which facilitates threading the knitting thread that has passed through the upper wire guiding rings 304 through multiple lower wire guiding rings 305 in sequence and exporting the knitting thread from the knitting thread outlet ring 306, enabling the knitting thread to provide tensile support for the magnetic strip 203 and thus maintaining the horizontal state of the magnetic strip 203.

[0027] Working principle: The bottom plate 201 defines the position of the U-shaped frame 202, facilitating the fixation of the bottom plate 201 on the winding arm of the circular knitting machine and fixing the U-shaped frame 202 for installation purposes. The U-shaped frame 202 defines the position of the magnetic strip 203, and the magnetic strip 203 and the U-shaped frame 202 define the position of the positioning rod 204, facilitating the positioning of the magnetic strip 203 in the U-shaped frame 202 by the positioning rod 204 and enabling the magnetic strip 203 to perform a lever movement in the U-shaped frame 202. The magnetic strip 203 defines the position of the gravity block 205, and the bottom plate 201 and the magnetic strip 203 define the position of the first magnetic attraction block 206, facilitating the fixation of the gravity block 205 to increase the weight of the left end of the magnetic strip 203. Thus, when the thread breaks, the magnetic strip 203 is no longer supported by the tensile force of the knitting thread, causing the left end of the magnetic strip 203 to tilt downward and adsorb on the first magnetic attraction block 206 to clamp the broken knitting thread. The bottom plate 201 defines the position of the support rod 301, and the support rod 301 defines the position of the mounting plate 302, facilitating the fixation of the support rod 301 for support purposes and fixing the mounting plate 302 for installation purposes. The mounting plate 302 defines the position of the knitting thread guiding ring 303, and the magnetic strip 203 defines the position of the upper wire guiding ring 304, facilitating the threading of the knitting thread through the knitting thread guiding ring 303 and successively through multiple upper wire guiding rings 304 to guide the knitting thread. The magnetic strip 203 defines the position of the lower wire guiding ring 305, and the mounting plate 302 defines the position of the knitting thread outlet ring 306, facilitating the threading of the knitting thread that has passed through the upper wire guiding ring 304 successively through multiple lower wire guiding rings 305 and exporting the knitting thread from the knitting thread outlet ring 306, enabling the knitting thread to provide tensile support to the magnetic strip 203, thereby maintaining the horizontal state of the magnetic strip 203. The support rod 301 defines the position of the top plate 101, and the top plate 101 and the magnetic strip 203 define the position of the second magnetic attraction block 102, facilitating the fixation of the top plate 101 to fix the second magnetic attraction block 102. Thus, when the thread breaks, the right end of the magnetic strip 203 tilts upward and adsorbs on the second magnetic attraction block 102 to clamp the broken thread, using the second line of defense to enhance the clamping effect and prevent the first line of defense from failing to clamp due to the too-fast rebound of the broken thread.

[0028] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than limiting the protection scope of the present invention. Any simple modification or equivalent replacement of the technical solution of the present invention by those of ordinary skill in the art shall not depart from the essence and scope of the technical solution of the present invention.
