Description

Technical Field

[0001] This invention relates to the field of small circular knitting machine technology, specifically to a small circular knitting machine with convenient line changing and its usage method. Background Technology

[0002] Small circular knitting machines are mainly used to produce seamless knitted garment fabrics or fabrics of special specifications. Their advantages include reduced consumption and increased fabric utilization, along with lower power and electricity consumption, thus lowering production costs. Small circular knitting machines effectively reduce waste during production, especially in garment manufacturing enterprises, where they further improve fabric utilization. Furthermore, their application extends to producing seamless fabrics for fashionable underwear and other products. This production method is an innovation from traditional methods, and the products have gained recognition in domestic and international markets. The design of small circular knitting machines incorporates shock absorption. Through a shock-absorbing single-sided frame structure, including the frame body, support plate, support feet, and shock-absorbing components, not only is the stability of the support feet improved, but the shock-absorbing components also effectively dampen the frame body, ensuring stable operation and extending the machine's lifespan. Small circular knitting machines house yarn spools, which need to be replaced after use. However, due to the high position of the yarn spool supports, replacing the spools and yarn can be inconvenient.

[0003] Therefore, it is necessary to invent a small circular knitting machine that is easy to change lines and its usage method. Summary of the Invention

[0004] To address the aforementioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0005] A small circular knitting machine with convenient cable changing includes a small circular knitting machine body, a first support frame, a second support frame, and a cable inlet frame. The first support frame and the cable inlet frame are respectively installed on the top of the small circular knitting machine body, and the second support frame is installed on top of the first support frame.

[0006] The inner side of the support frame 2 is equipped with a feeding mechanism for the wire spool;

[0007] A feeding mechanism is installed above the second support frame, which can feed the wire spool.

[0008] Preferably, the unloading mechanism includes a support ring and a support block 1. The support ring is installed on the upper end of the support frame 2, and the support block 1 is installed on the inner wall of the support frame 2.

[0009] Preferably, a second support block is rotatably mounted on the inner side of the first support block, a pressure rod is mounted on the upper end of the second support block, a first support shaft is mounted on the other end of the second support block, an electromagnet is rotatably mounted on the outer wall of the first support shaft, a spool is inserted into the first support shaft, an electromagnet is mounted on one end of the spool, and the second electromagnet magnetically attracts the first electromagnet.

[0010] Preferably, a connecting ring one is also installed on the inner wall of the support ring, and a connecting ring two is installed on the upper end of the support block two. A reset spring is connected between the connecting ring one and the connecting ring two.

[0011] Preferably, a support rod is installed on the outer wall of the support ring, and a guide rail is installed at the lower end of the support rod at an angle.

[0012] Preferably, the upper mechanism includes a first conveyor belt, a support leg plate, and a second conveyor belt. The second conveyor belt is connected to the upper end of the first conveyor belt, and the support leg plate is installed at the bottom of the first conveyor belt.

[0013] Preferably, support side plates are installed on both sides of the second conveyor belt, and a support top plate is installed on the upper end of the support side plate. Support rods are connected to the upper end of the small circular machine body and the side end of the support top plate.

[0014] Preferably, a motor is installed on the top of the supporting top plate, a first gear is installed on the output end of the motor, a support base is rotatably installed on the inner wall of the supporting top plate, a second gear is installed on the upper end of the support base, the second gear meshes with the first gear, and an electric push rod is installed inside the lower end of the support base.

[0015] Preferably, a connecting plate is installed at the output end of the electric push rod one, a through hole is formed on the inner wall of the connecting plate, a support shaft two is installed at the front end of the connecting plate, a push plate is inserted into the through hole, an electric push rod two is installed at the rear end of the connecting plate, and the output end of the electric push rod two is connected to the push plate.

[0016] A convenient method for changing the thread on a small circular knitting machine includes the following operating steps:

[0017] S1: The motor drives the first gear to rotate, the first gear drives the second gear to rotate, and the second gear drives the support base, electric push rod one and support shaft two to rotate, adjusting the orientation of support shaft two;

[0018] S2: The electric push rod 2 pushes the push plate, causing the push plate to move above the pressure rod. The electric push rod pushes the connecting plate and the push plate, the push plate presses down the pressure rod, and the pressure rod presses down the support block 2, causing the support block 2 and the support shaft 1 to rotate downward about the connection point between the support block 2 and the support shaft 1. The return spring is stretched.

[0019] S3: Electromagnet 1 and Electromagnet 2 are de-energized and lose their magnetism. Due to the inclination of support shaft 1, the spool and electromagnet 2 slide down into the guide rail, and then slide out through the guide rail. Finally, the push plate resets, support shaft 2 rises and resets to one end of conveyor belt 2, and the reset spring pulls support shaft 1 back to a horizontal state.

[0020] S4: Place the full-length spools into the narrow conveyor belt one in sequence, and then transport them to the conveyor belt two. The next spool pushes the previous spool into the support shaft two.

[0021] S5: The electric push rod pushes the connecting plate to align the second support shaft with the first support shaft. The second electric push rod pushes the push plate, which in turn pushes the bobbin, causing it to insert into the first support shaft. Both electromagnets 1 and 2 are energized and generate magnetism, thus magnetically attracting and connecting the bobbin. This prevents the bobbin from falling off the first support shaft while it rotates. Finally, the second support shaft rises and resets to one end of the second conveyor belt to complete the wire changing.

[0022] S6: Similarly, all the wire drums in the support ring can be quickly and automatically changed in the same way.

[0023] Compared with existing technologies:

[0024] By setting a wire unloading mechanism at the upper end of the small circular knitting machine, the used wire spool slides down into the guide rail by pressing down on the support shaft, and then slides down and is removed by the guide rail.

[0025] An upper mechanism is set above the lower mechanism. The wire drum is conveyed by conveyor belt one and conveyor belt two. The wire drum is supported by support shaft two and moved to support shaft one. The push plate pushes the wire drum on support shaft two onto support shaft one, so that the small circular knitting machine can change the line quickly and conveniently. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0034] Example 1: As Figures 1-5 ;

[0035] The device includes a small circular knitting machine body 1, a first support frame 11, a second support frame 12, and a wire feed frame 13. The first support frame 11 and the wire feed frame 13 are respectively installed on the top of the small circular knitting machine body 1. The second support frame 12 is installed on the top of the first support frame 11. The inner side of the second support frame 12 is provided with a wire feeding mechanism 2 for feeding the wire spool. By setting the wire feeding mechanism at the upper end of the small circular knitting machine, the wire spool after use is pressed down on the support shaft and tilted to slide into the guide rail, and then guided by the guide rail to slide down and be removed.

[0036] The unloading mechanism 2 includes a support ring 21 and a first support block 22. The support ring 21 is installed on the upper end of the second support frame 12 and is used to support and install the first support rod 26 and the first connecting ring 23. The first support block 22 is installed on the inner wall of the second support frame 12 and is used to support and install the second support block 221. The second support block 221 is rotatably installed on the inner side of the first support block 22 and is used to support and install the first support shaft 24. A pressure rod 222 is installed on the upper end of the second support block 221. The pressure rod 222 is used to press down the second support block 221 and the first support shaft 24, causing the first support shaft 24 to tilt downwards. The other end of the second support block 221 is equipped with the first support shaft 24, which is used to support the installation of the spool 25. An electromagnet 241 is rotatably mounted on the outer wall of the first support shaft 24. The electromagnet 241 is used to magnetically attract the second electromagnet 251, so that the spool 25 rotates on the first support shaft 24 without detaching from it. The spool 25 is inserted into the first support shaft 24. The spool 25 is wound with a small circular knitting machine thread. Replacing the spool 25 facilitates thread replacement on the small circular knitting machine. An electromagnet 251 is installed at one end of the spool 25. When energized, the electromagnet 251 generates magnetism and attracts and connects to the first electromagnet 241. When de-energized, the electromagnet 251 loses its magnetism and detaches from the first electromagnet 241, while the second electromagnet 251 magnetically attracts the first electromagnet 241. A connecting ring 23 is also installed on the inner wall of the support ring 21. A connecting ring 232 is installed on the upper end of the second support block 221. The connecting rings 23 and 23... 2 is used to support the return spring 231. The return spring 231 is connected between the first connecting ring 23 and the second connecting ring 232. When the support shaft 24 is pressed down and tilted, the return spring 231 pulls back to restore the support. The return spring 231 can be replaced. The outer wall of the support ring 21 is equipped with the support rod 26. The support rod 26 is used to support the guide rail 27. The lower end of the support rod 26 is inclined to install the guide rail 27. The spool 25 falls into the guide rail 27 and slides out through the guide rail 27.

[0037] Motor 34 drives the first gear 35 to rotate, the first gear 35 drives the second gear 36 to rotate, the second gear 36 drives the support base 37, the electric push rod 371, and the support shaft 381 to rotate, adjusting the orientation of the support shaft 381. The electric push rod 39 pushes the push plate 391, moving the push plate 391 above the pressure rod 222. The electric push rod 371 pushes down the connecting plate 38 and the push plate 391, the push plate 391 presses down the pressure rod 222, and the pressure rod 222 presses down the support block 221, causing the support block 221 to... 1. Support shaft 24 rotates downward with the connection between support block 221 and support block 22 as the pivot. The return spring 231 is stretched, and electromagnets 241 and 251 are de-energized and lose their magnetism. Due to the inclination of support shaft 24, the bobbin 25 and electromagnet 251 slide down into the guide rail 27 and are then guided out by the guide rail 27. Finally, the push plate 391 resets, support shaft 381 rises and resets to one end of conveyor belt 32, and the return spring 231 pulls support shaft 24 back to a horizontal state.

[0038] Example 2: As Figure 1 , Figure 2 and Figure 6 ;

[0039] The machine includes a small circular knitting machine body 1, a first support frame 11, a second support frame 12, and an infeed frame 13. The first support frame 11 and the infeed frame 13 are respectively installed on the top of the small circular knitting machine body 1. The second support frame 12 is installed on the top of the first support frame 11. An upper wire feeding mechanism 3 is set above the second support frame 12. The upper wire feeding mechanism 3 can feed the wire spool. The upper wire feeding mechanism is set above the lower wire feeding mechanism. The wire spool is conveyed by the first conveyor belt and the second conveyor belt. The second support shaft moves the wire spool to the first support shaft. The push plate pushes the wire spool on the second support shaft to the first support shaft, so that the small circular knitting machine can change wires quickly and conveniently.

[0040] The upper mechanism 3 includes a first conveyor belt 31, a support leg plate 311, and a second conveyor belt 32. The second conveyor belt 32 is connected to the upper end of the first conveyor belt 31. The first conveyor belt 31 and the second conveyor belt 32 are used to convey the wire drum 25. The second conveyor belt 32 is set above the support ring 21. The support leg plate 311 is installed at the bottom of the first conveyor belt 31. The support leg plate 311 can be fixed by bolts. The support leg plate 311 is used to support the first conveyor belt 31. Support side plates 331 are installed on both sides of the second conveyor belt 32. The support side plates 331 are used to support the top support plate 33. The top support plate 33 is installed at the upper end of the support side plates 331. The top support plate 33 is used to support the motor 34 and the support seat 37. The upper end of the small circular machine body 1 and the side end of the top support plate 33 are connected to the second support rod 332. The second support rod 332 is also used to support the top support plate 33, increasing the stability of the top support plate 33.

[0041] A motor 34 is mounted on the top of the supporting top plate 33. The motor 34 drives the first gear 35 to rotate. The output end of the motor 34 is equipped with the first gear 35, which drives the second gear 36 to rotate. A support base 37 is rotatably mounted on the inner wall of the supporting top plate 33. The support base 37 supports the rotation of the connecting plate 38. The upper end of the support base 37 is equipped with the second gear 36, which drives the support base 37 to rotate. The second gear 36 meshes with the first gear 35. An electric push rod 371 is installed inside the lower end of the support base 37. The electric push rod 371 is used to push and pull the connecting plate 38 to adjust the height of the second support shaft 381. The output end of the electric push rod 371 is equipped with the connecting plate 38, which is used for... The second support shaft 381 and the second electric push rod 39 are supported and installed. The inner wall of the connecting plate 38 has a through hole 382, ​​which is used to place the push plate 391. The second support shaft 381 is installed at the front end of the connecting plate 38. The second support shaft 381 is used to insert the support spool 25. The push plate 391 is inserted into the through hole 382. The push plate 391 can not only push the spool 25 on the second support shaft 381 onto the first support shaft 24, but also press down the pressure rod 222, so that the second support block 221 and the first support shaft 24 tilt downward. The second electric push rod 39 is installed at the rear end of the connecting plate 38. The second electric push rod 39 is used to push and adjust the position of the push plate 391. The output end of the second electric push rod 39 is connected to the push plate 391.

[0042] The fully loaded spools 25 are sequentially placed into the narrow conveyor belt 31 and transported to the second conveyor belt 32. Each subsequent spool 25 pushes the preceding spool 25 into the second support shaft 381. The electric push rod 371 pushes down the connecting plate 38, aligning the second support shaft 381 with the first support shaft 24. The electric push rod 39 pushes the push plate 391, which in turn pushes the spool 25 into the first support shaft 24. Both the first electromagnet 241 and the second electromagnet 251 are energized and magnetically attracted to each other, preventing the spool 25 from falling off the first support shaft 24 while rotating. Finally, the second support shaft 381 rises and returns to one end of the second conveyor belt 32, completing the wire changing process. This process is repeated for all the spools 25 in the support ring 21, allowing for rapid and automatic wire changing.

[0043] The working principle of this invention is as follows: Motor 34 drives the first gear 35 to rotate, the first gear 35 drives the second gear 36 to rotate, the second gear 36 drives the support base 37, the electric push rod 371, and the support shaft 381 to rotate. Adjusting the orientation of the support shaft 381, the electric push rod 39 pushes the push plate 391, causing the push plate 391 to move above the pressure rod 222. The electric push rod 371 pushes down the connecting plate 38 and the push plate 391, and the push plate 391 presses down on the pressure rod. 222, the pressure rod 222 presses down on the support block 221, causing the support block 221 and the support shaft 24 to rotate downwards around the connection between the support block 221 and the support block 221. The return spring 231 is stretched, and both electromagnets 241 and 251 are de-energized and lose their magnetism. Due to the inclination of the support shaft 24, the spool 25 and the electromagnet 251 slide downwards into the guide rail 27, and then slide out through the guide rail 27. Finally, the push plate 391 resets, and the support... Support shaft 281 rises and resets to one end of conveyor belt 22. Return spring 231 pulls support shaft 24 back to a horizontal position. Fully loaded bobbins 25 are sequentially placed into narrow conveyor belt 31 and transported to conveyor belt 22. Each subsequent bobbin 25 pushes the preceding bobbin 25 into support shaft 281. Electric push rod 371 pushes down connecting plate 38, aligning support shaft 281 and support shaft 24. Electric push rod 39... Pushing the push plate 391 pushes the bobbin 25, causing it to insert into the support shaft 24. Electromagnets 241 and 251 are energized and magnetically attracted to each other, preventing the bobbin 25 from falling off the support shaft 24 while rotating. Finally, the support shaft 381 rises and resets to one end of the conveyor belt 32 to complete the wire changing. This process is repeated for all the bobbins 25 in the support ring 21, allowing for rapid and automatic wire changing in the same way.

[0044] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
