The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present invention.

[0033] See also Figure 1-14 , an embodiment of the present invention: a needle riveting machine, comprising a base plate 1, a clamping assembly 4 for clamping a knitting needle 10 is provided on the base plate 1, and an extrusion assembly 3 for causing the knitting needle 10 to deform is also provided on one side of the base plate 1; the extrusion assembly 3 comprises a first adjustment assembly 30 and a second adjustment assembly 31; wherein the first adjustment assembly 30 comprises a support plate 32 and a linkage seat 34 and a rack 35 slidably mounted on the support plate 32; wherein the second adjustment assembly 31 is fixedly mounted on the linkage seat 34; the linkage seat 34 is connected to a screw rod 33, and the screw rod 33 is meshed with the rack 35 through a gear 36; the second The adjusting assembly 31 includes a carrying plate 310 and a supporting seat 313 having one end connected to the carrying plate 310 by an axial pin; one side of the carrying plate 310 is slidably matched with the guide rail 39 provided on the supporting plate 32 through a slider 316, and the rack 35 is prompted to slide on the supporting plate 32 through a first driving member 38, so that the second adjusting assembly 31 slides along the guide rail 39; based on this, the slider 316 cooperates with the guide rail 39, so that the roller 321 can move in a directional manner and it can also be avoided that when the roller 321 moves on the outer wall of the knitting needle 10, the deformation zone of the knitting needle 10 cannot be completely clamped on the connecting rope 9 due to poor contact.

[0034] The supporting plate 310 is connected to the shaft pin hole 331 provided on the supporting seat 313 through the shaft pin rod 315 provided thereon, and a first fixing plate 311 is further provided on one side of the supporting plate 310, and a first adjusting rod 312 is provided on the first fixing plate 311; one end of the first adjusting rod 312 passes through the first fixing plate 311 and is connected to the first connecting hole 324 provided on the supporting seat 313, and the supporting seat 313 is rotated along the shaft pin rod 315 by rotating the first adjusting rod 312. In specific use, the first connecting hole 324 is an internal threaded hole, and the first adjusting rod 312 is a bolt, so that when the first adjusting rod 312 rotates, one end of the supporting seat 313 can be caused to rotate along the shaft pin rod 315, thereby adjusting the angle between the roller 321 and the outer wall surface of the knitting needle 10, and after the angle is adjusted, since the first adjusting rod 312 and the first connecting hole 324 are threadedly matched, the position of the roller 321 is locked.

[0035] The support seat 313 is also provided with a screw rod 318 and a sliding seat 314 threadedly matched with the screw rod 318, and a bracket 320 is installed on the sliding seat 314, and a roller 321 is also provided at one end of the bracket 320 away from the sliding seat 314, and the sliding seat 314 is moved by the second driving member 319 to make the roller 321 move laterally. Based on this, the second driving member 319 is used to make the roller 321 slide along the central axis of the knitting needle 10, so that the second driving member 319 can be used to promote the movement stroke of the sliding seat 314 to adjust the length of the deformation zone of the knitting needle 10.

[0036] In summary, after one end of the knitting needle 10 is inserted into the clamping assembly 4, the user inserts one end of the connecting rope 9 into the knitting needle 10, and uses the first driving member 38 to cause the roller 321 to move along the radial direction of the knitting needle 10, so as to apply pressure to cause the knitting needle 10 to shrink along its radial direction, so as to reliably rivet the connecting rope 9 into the knitting needle. At the same time, the second driving member 319 is used to cause the roller 321 to fit the outer wall surface of the knitting needle 10 and move along the central axis of the knitting needle 10 to expand the contraction length of the knitting needle 10, so that the connecting rope 9 located inside the knitting needle 10 can be reliably riveted into the knitting needle 10, so as to enhance the riveting strength between the knitting needle 10 and the connecting rope 9; in addition, the gear transmission is realized by the meshing of the rack 35 and the gear 36, so that the reliable transmission of power and the stability of the equipment during operation can be guaranteed, and the vibration and noise generated during the operation of the equipment can be reduced, and reliable pressure can be provided for the roller 321 to improve the contraction effect of the knitting needle 10.

[0037] At the same time, the first adjusting rod 312 is rotated to cause the supporting seat 313 to rotate on the carrying plate 310 to adjust the angle between the roller 321 and the facing surface of the knitting needle 10, so that the roller 321 can cause the deformation zone of the knitting needle 10 to be truncated cone-shaped, thereby gradually shrinking the outer diameter of the knitting needle 10 to further enhance the connection strength between the knitting needle 10 and the connecting rope 9;

[0038] In addition, since the device can realize the automatic movement of the roller 321 by using the first driving member 38 and the second driving member 319, the user only needs to insert the connecting rope 9 into the knitting needle 10 and start the device to realize the automatic riveting between the connecting rope 9 and the knitting needle 10, thereby improving the riveting efficiency of the connecting rope 9 and the knitting needle 10 and improving the riveting quality between the connecting rope 9 and the knitting needle 10. Based on this, the deformation area of ​​the knitting needle 10 can be truncated by the mutual cooperation of the two driving members, so as to gradually rivet the connecting rope 9 in the knitting needle 10, so as to improve the connection strength between the knitting needle 10 and the connecting rope 9.

[0039] Furthermore, the bracket 320 is connected to the sliding seat 314 through a connecting block 317; wherein, a fixing hole 326 is provided on the connecting block 317, and a shaft passes through a circular hole 322 provided on the bracket 320 and is connected to the fixing hole 326, so that one end of the bracket 320 can rotate on the connecting block 317. Therefore, when one end of the bracket 320 is rotatably mounted on the fixing hole 326, so that one end of the bracket 320 can rotate on the connecting block 317, the angle between the roller 321 and the outer wall surface of the knitting needle 10 can be further adjusted.

[0040] Based on this, the roller 321 rotates on the connecting block 317 under the action of two driving parts and the bracket 320, so that the roller 321 has the ability to adjust at multiple angles, so as to expand the adaptability of the device, and thus enable the device to complete the riveting of knitting needles 10 of yarn needles of different diameters and the connecting rope 9.

[0041] In order to facilitate the adjustment of the position of the bracket 320 and the locking of the adjusted position, a second fixing plate 328 is further provided on the connecting block 317, and a second adjusting rod 329 is further provided on the second fixing plate 328. The second adjusting rod 329 passes through the second fixing plate 328 and is threadedly connected to the second connecting hole 325 provided on the bracket 320. Based on this, the rotation of the second adjusting rod 329 can drive one end of the bracket 320 to rotate on the connecting block 317, and after the rotation, since the second adjusting rod 329 and the second connecting hole 325 are threadedly connected, it is ensured that the bracket 320 can be stably and reliably locked after the position is adjusted.

[0042] Furthermore, since the connecting block 317 is also provided with a guide groove 327, and the bracket 320 is also provided with a mounting hole 323, and the shaft installed in the mounting hole 323 is slidably matched with the guide groove 327, so that the guide groove 327 guides the bracket 320 to move. Based on this, the shaft in the mounting hole 323 is connected with the guide groove 327, so that the bracket 320 can rotate more stably and reliably on the connecting block 317, especially, it can avoid the phenomenon that the bracket 320 is not firmly in contact with the connecting block 317 due to excessive rotation, and then the deformation zone of the knitting needle 10 is uneven. Based on this, while ensuring the reliable molding of the deformation zone, the deformation zone can also be continuously molded; especially, while ensuring the riveting quality of the connecting rope 9 and the knitting needle 10, the aesthetics of the deformation zone can also be improved.

[0043] In addition, since the first fixing plate 311 and the second fixing plate 328 are both provided with waist-shaped grooves 330, the two adjustment rods have sufficient movable space, reducing the interference of the adjustment rods during adjustment; at the same time, the support plate 32 is also provided with a limit rod 37, and the movement stroke of the rack 35 is limited by the limit rod 37. Specifically, the limit rod 37 is threadedly connected to the support plate 32, so that the gap between the limit rod 37 and the rack 35 can be enlarged by rotating the limit rod 37 counterclockwise, so that the movement range of the rack 35 becomes larger; conversely, the limit rod 37 can be rotated clockwise to reduce the movement range of the rack 35. Based on this, the movement stroke of the linkage seat 34 can be further enlarged or reduced by rotating the limit rod 37, so that the roller 321 can roll the knitting needles 10 of different diameters.

[0044] In order to ensure that the knitting needle 10 can be reliably clamped and avoid the knitting needle 10 from shifting during the riveting process, the clamping assembly 4 includes a frame 40 and a chuck assembly 43 installed on the frame 40; the chuck assembly 43 includes a base 48 and a guide tube 44 installed in the base 48; one end of the guide tube 44 is connected to a chuck 47, and the other end of the guide tube 44 is connected to a linkage tube 45; wherein one end of the chuck 47 is connected to the linkage tube 45, and the chuck 43 is slid in the guide tube 44 by pulling the linkage tube 45.

[0045] Based on this, the linkage tube 45 is used to slide rightward in the guide tube 44, and at this time, the end of the clamp 47 exposed outside the guide tube 44 is compressed to close to the center of the circle, thereby clamping the knitting needle 10; on the contrary, when the linkage tube 45 slides leftward, the end of the clamp 47 exposed outside the guide tube 44 expands radially outward under the action of its own elastic force, and at this time, it is convenient to remove the knitting needle 10 from the clamp 47. In this way, the knitting needle 10 is convenient to take and put while ensuring that the knitting needle 10 is reliably clamped. Among them, the inner wall surface of the guide tube 44 is provided with a protrusion, and the protrusion is used to adapt and connect with the groove provided on the clamp 47 to ensure that the guide tube 44 drives the clamp 47 to rotate reliably.

[0046] Furthermore, since the fourth driving member 41 on one side of the frame 40 is connected to the linkage tube 45 through the coupling 46, and the linkage tube 45 is prompted to slide in the guide tube 44 through the fourth driving member 41, the fourth driving member 41 can be used to drive one end of the chuck 47 to slide in the guide tube 44.

[0047] Furthermore, since the frame 40 is also provided with a fifth driving member 42, and the guide tube 44 is caused to rotate in the base 48 by the fifth driving member 42, specifically, the fifth driving member 42 causes the guide tube 44 to rotate through a belt, and since the guide tube 44 can rotate, it drives the knitting needle 10 to rotate, so that the deformation zone of the knitting needle 10 is more beautiful and the molding quality of the deformation zone is further improved.

[0048] On the basis of the above scheme, since a backrest assembly 2 is also provided on the base plate 1, the backrest assembly 2 includes a base plate 20 and a movable frame 22 slidably installed on the base plate 20, and a support wheel 21 is provided on the movable frame 22; the movable frame 22 is prompted to slide on the base plate 20 by a third driving member 23, so the third driving member 23 is utilized to prompt the support wheel 21 and the roller 321 to move synchronously, so that the molding quality of the deformation zone can be further guaranteed, especially, the phenomenon that the knitting needle 10 is completely deformed due to excessive squeezing of the roller 321 on the knitting needle 10 can be avoided. Based on this, the molding quality between the knitting needle 10 and the connecting rope 9, as well as the aesthetics of the deformation zone after molding can be further guaranteed.

[0049] In addition, a box body 5 is provided below the base plate 1, and the backrest assembly 2 is covered on the box body 5 by a first protective cover 6, the extrusion assembly 3 is covered on the box body 5 by a second protective cover 7, and the clamping assembly 4 is covered on the box body 5 by a third protective cover 8.

[0050] Based on this, the bottom plate 1 can be lifted up by the box body 5 to facilitate the user to rivet the knitting needles. At the same time, the internal space of the box body 5 can also be used to facilitate the access to the raw materials and finished products of the knitting needles at any time. In addition, the setting of the three protective covers makes the exterior of the device tidy and the three protective covers can be used to protect the corresponding components.

[0051] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
