One side of the inclined groove block 104 is fixedly connected to the telescopic end of the first electric push rod 103. The outside of the inclined groove block 104 slides between the seven-shaped block 1 and the fixed block 102. Both ends of the connecting block 105 are respectively fixedly connected to the other side of the seven-shaped block 1 and one side of the fixed block 102. One end of the connecting column 106 is fixedly connected to the bottom of the crochet member 101. The other end of the connecting column 106 is slidably connected to the middle of the connecting block 105. One end of the extension block 107 is fixedly connected to one side of the connecting column 106. The other end of the extension block 107 is slidably connected and clamped inside the inclined groove block 104.

[0037] Among them, the electric push rod 103 is an existing device, and it is also externally provided with wires, switches, and power sockets. Since they are not the main technical features, they will not be elaborated here.

[0038] When the operator needs to replace the knitting thread, the operator energizes the electric push rod 103 through the wire, starts the electric push rod 103 through the switch, so that the electric push rod 103 pushes the chute block 104 to slide. Through the sliding of the chute block 104, the extension block 107 drives the crochet piece 101 to slide on one side of the seven-shaped block 1 through the connecting column 106. Through the reciprocating push of the electric push rod 103, the crochet piece 101 hooks the knitting thread into the inside of the card wire groove 203.

[0039] Refer to Figure 1 、 3 As shown in FIGS. 3 and 4, the trimming mechanism 2 includes a long strip groove 201 opened on one side of the upper end of the seven-shaped block 1, a square groove 202 opened at the bottom of the long strip groove 201 at the upper end of the seven-shaped block 1, a card wire groove 203 opened at the top of one side of the seven-shaped block 1, a chute 204 opened in the middle of the lower surface of the square groove 202. The outer shell of the electric push rod 205 is fixedly installed on one side inside the square groove 202. One side of the U-shaped block 206 is fixedly connected to the telescopic end of the electric push rod 205. The bottom of the U-shaped block 206 is slidably connected to the inside of the chute 204. Both ends of the fixed column 207 are respectively fixedly connected to the surface of the square groove 202 and the bottom of the fixing plate 208. The middle of the long strip block 209 is rotatably connected to the inside of the other side of the U-shaped block 206. The middle of the long strip block 210 is rotatably connected to the inside of the other side of the U-shaped block 206. The long strip block 209 is rotatably connected above the long strip block 210. The sliding tracks 211 are symmetrically opened through both sides of the middle of the fixing plate 208. One ends of the two moving columns 212 are respectively fixedly connected to one end of the long strip block 209 and one end of the long strip block 210. The other ends of the two moving columns 212 are slidably connected to the inside of the sliding tracks 211.

[0040] Among them, the electric push rod 205 is an existing device, and it is also externally provided with wires, switches, and power sockets. Since they are not the main technical features, they will not be elaborated here.

[0041] After the fixing of the yarn is completed, the operator energizes the second electric push rod 205 through a wire and starts the second electric push rod 205 through a switch. At this time, the U-shaped block 206 begins to slide inside the chute 204. Through the sliding of the U-shaped block 206, the moving column 212 begins to slide inside the sliding track 211. At the same time, the first long block 209 and the second long block 210 begin to move along with the U-shaped block 206. When the moving column 212 continues to slide inside the sliding track 211, the moving column 212 starts to slide centering according to the holes of the sliding track 211. Through the centering sliding of the moving column 212, the first long block 209 and the second long block 210 begin to rotate and cut the yarn. Subsequently, the second electric push rod 205 is controlled through the switch to make the U-shaped block 206 return to its initial state, and the trimming of the yarn can be completed.

[0042] Refer to Figure 1 、 5 、6, the wire clamping mechanism 3 includes a square groove two 301 opened on one side surface of the fixed block 102. Auxiliary grooves 302 are opened on both sides inside the square groove two 301. The outer shell of the motor 303 is fixedly installed in the middle of the upper end of one side of the fixed block 102. The middle of the full gear one 304 is fixedly connected to the output end of the motor 303. One side of the fixed bracket 305 is fixedly connected to one side surface of the fixed block 102. The middle of the full gear two 306 is rotatably connected and clamped on the outer wall of the fixed bracket 305. The outside of the full gear two 306 meshes with the full gear one 304. The bottom of the half gear 307 is fixedly connected to the top of the full gear two 306. The middle of the half gear 307 is rotatably connected to the outside of the fixed bracket 305. One side of the half gear 307 meshes with the tooth groove of the rack 308. One side of the rack 308 is slidably connected inside the auxiliary groove 302. The other side of the rack 308 is rotatably connected to one end of the first rotating rod 311. A guiding groove 309 is opened on the upper surface of the long groove 201. A straight groove 310 is opened in the middle of the guiding groove 309 on the upper surface of the long groove 201. One end of the first sliding column 312 is fixedly connected to the other end of the first rotating rod 311. The other end of the first sliding column 312 is slidably connected inside the guiding groove 309. One side of the second rotating column 313 is rotatably connected to the middle of the first rotating rod 311. One end of the second sliding column 314 is fixedly connected to one side of the second rotating column 313. The other end of the second sliding column 314 is slidably connected inside the straight groove 310.

[0043] The motor 303 is an existing device, and there are also wires, switches and power sockets outside. Since it is not a main technical feature, it will not be described in detail here.

[0044] When the knitting thread is hooked into the inside of the wire clamping groove 203, the operator controls the forward and reverse rotation of the motor 303 according to the different knitting threads. Then, the motor 303 is powered on through the wire, and the motor 303 is started through the switch. The full gear one 304 begins to drive the full gear two 306 to rotate outside the fixed bracket 305. Through the rotation of the full gear two 306, the half gear 307 begins to drive the rack 308 to slide inside the auxiliary groove 302 and the long strip groove 201. Through the sliding of the rack 308, the rotating rod one 311 begins to move inside the long strip groove 201. Since the sliding column one 312 on one side of the rotating rod one 311 is restricted inside the guiding groove 309, the rotating rod one 311 begins to rotate inside the long strip groove 201 at this time. While the rotating rod one 311 is moving and rotating, the rotating column two 313 begins to slide on the surface of the long strip groove 201. Since the sliding column two 314 is restricted by the straight running groove 310, the rotating column two 313 can only translate and move in a straight line along the surface of the long strip groove 201. When the front end of the rotating column two 313 passes through the wire clamping groove 203, the front end of the rotating column two 313 will fix the knitting thread to be replaced inside the wire clamping groove 203. By fixing the rotating rod one 311, the knitting thread can be prevented from curling when being trimmed.

[0045] The implementation principle of the wire cutting mechanism of a knitting glove machine in an embodiment of the present application is as follows: When the operator needs to replace the knitting thread, the operator starts the electric push rod one 103 through the switch. The electric push rod one 103 pushes the inclined groove block 104 to make the extension block 107 slide. Through the sliding of the extension block 107, the connecting column 106 begins to drive the hook needle part 101 to hook the knitting thread to be replaced into the inside of the wire clamping groove 203. Then, the operator controls and starts the forward and reverse rotation of the motor 303 according to the different knitting threads. At this time, the fixed bracket 305 drives the full gear two 306 to rotate, the half gear 307 begins to drive the rack 308 to move, and the rotating rod one 311 begins to move inside the long strip groove 201 through the rack 308. Due to the restriction of the sliding column one 312, the rotating rod one 311 begins to move and rotate inside the long strip groove 201 at this time. At the same time, due to the restriction of the sliding column two 314 and the drive of the rotating rod one 311, the rotating column two 313 translates and moves in a straight line along the surface of the long strip groove 201 at this time. At the same time, the front end of the rotating column two 313 fixes the knitting thread inside the wire clamping groove 203.

[0046] After the knitting thread is fixed, the operator starts the electric push rod two 205 through the switch. At this time, the U-shaped block 206 begins to drive the long strip block one 209 and the long strip block two 210 to move. Through the movement of the long strip block one 209 and the long strip block two 210, the moving column 212 begins to slide inside the sliding track 211. When the moving column 212 slides in the center inside the sliding track 211, the trimming of the knitting thread can be completed.

[0047] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
