DETAILED DESCRIPTION

[0027] The embodiment of the present invention provides a cutter anti-snagging mechanism for a sock thread cutting machine, such as Figure 1-6 As shown, it includes two wire drums 1, and the silk thread passes through the two wire drums 1. The two wire drums 1 are arranged up and down. There is a 5 cm interval between the two wire drums 1. Two clamping components 3 are arranged in the interval. A cutter 5 is arranged on the right side of the two clamping components 3. After the two clamping components 3 clamp the silk thread, the cutter 5 is used to cut the silk thread.

[0028] The cutter 5 is in the shape of a long strip, and the cutter 5 is slidably matched with a cleaning assembly along the length direction, and the cleaning assembly includes two slide plates 7, two slide bars 71, a plurality of small springs 72 and two paddles 8, and the two slide plates 7 are respectively arranged on the upper and lower sides of the cutter 5. The slide bars 71 are respectively located at the left and right ends of the slide plates 7, and the slide bars 71 penetrate the two slide plates 7, one end of the small spring 72 is welded to the end of the slide bar 71, and the other end of the small spring 72 is welded to the end of the slide plate 7. The small spring 72 is in a squeezed state, so that the two slide plates 7 always have a force to approach each other.

[0029] The paddle 8 is arranged in an inclined state, one end of the paddle 8 is in contact with the cutter 5 , and the other end of the paddle 8 is fixedly mounted on the front side of the slide plate 7 .

[0030] The front of the cutter 5 is used to cut the wire, and a grinding stone 81 is fixedly installed at the lower end of the paddle 8, and the grinding stone 81 contacts the cutting surface of the cutter 5. A control module is also included, which is a conventional technical means for controlling the operation of various electronic parts.

[0031] Before work, the entire cleaning assembly is close to the end of the cutter 5. After the cutter 5 cuts the silk thread, the slide plate 7 moves forward to wipe the surface of the cutter 5 and push the hooked silk thread against the cutter 5. Avoid the silk thread from hooking the cutter 5.

[0032] The tool 5 also includes a magnetic plate 4, which is located at a gap and in front of the tool 5, with the N magnetic pole of the magnetic plate 4 located on the left and the S magnetic pole of the magnetic plate 4 located on the right. A magnetic strip 73 is fixedly installed on the back of the slide plate 7, and the S magnetic pole of the magnetic strip 73 faces forward. A rubber sheet 52 is fixedly installed on the back of the tool 5, and the rubber sheet 52 has a certain toughness. The end of the rubber sheet 52 can contact the slide plate 7.

[0033] Working principle: When the cutter 5 is in the S magnetic field of the magnetic plate 4, there is a repulsive force between the magnetic plate 4 and the magnetic strip 73. The cutter 5 rotates to cut the wire, and the slide plate 7 moves forward due to inertia, and the rubber sheet 52 contacts the slide plate 7. The movement of the slide plate 7 is hindered by the double buffering of the rubber sheet 52 and the magnetic field.

[0034] After the cutter 5 cuts the wire, the cutter 5 faces the N magnetic pole of the magnetic plate 4, and the slide plate 7 enters the N magnetic field, generating a mutual attraction force between the magnetic plate 4 and the magnetic strip 73. The slide plate 7 moves forward through the suction force, the rubber sheet 52 bends, and finally the slide plate 7 approaches the front end of the cutter 5.

[0035] When the tool 5 is reset and re-enters the S magnetic field of the magnetic plate 4 , the slide plate 4 quickly approaches the end of the tool 5 .

[0036] The clamping assembly 3 includes a base plate 31, a rotating block 32, a mountain-shaped piece 33, a clamping piece 34, and a large spring 35. The rotating block 32 is symmetrically pivoted on the upper and lower sides of the base plate 31, and the two rotating blocks 32 are connected by the mountain-shaped piece 33, and the ends of the mountain-shaped piece 33 are welded to the rotating block 32.

[0037] A motor 331 is fixedly installed near the end of the wire on the mountain-shaped piece 33 . The transmission shaft of the motor 331 faces the wire and is fixedly installed with the clamp 34 . One end of the large spring 35 is welded to the base plate 31 , and the other end of the large spring 35 is welded to the mountain-shaped piece 33 .

[0038] It also includes a steel wire 36 and a second motor 37. The substrate 31 is fixedly installed with the second motor 37 on the side away from the wire. One end of the steel wire 36 is fixedly tied to the mountain-shaped piece 33, and the other end of the steel wire 36 passes through the substrate 31 and is fixedly tied to the transmission shaft of the second motor 37.

[0039] When the motor 2 37 rotates to wind the steel wire 36, the steel wire 36 pulls the mountain-shaped piece 33, so that the clamping pieces 34 of the two clamping components 3 move away from each other. When the motor 2 37 rotates in the opposite direction, the two mountain-shaped pieces 33 move closer to each other, so that the clamping pieces 4 fit together to clamp the wire. The motors 1 331 of the two clamping components 3 move synchronously. The motor 1 331 located at the top can deflect 15° to the front side, and the motor 1 331 located at the bottom can deflect 15° to the back side, so as to tighten the wire slightly, which is beneficial for the cutting of the tool 5.

[0040] A toothed ring 11 is welded at the end of the bobbin 1, and a rack 2 is slidably matched on the outside of the bobbin 1. The rack 2 is telescopically driven by an electric push rod, which is a conventional technical means and will not be described in detail. The rack 2 is meshed with the toothed ring 11, and a connecting plate 6 is provided on the outer cover of the bobbin 1.

[0041] A light beam receiver 61 is fixedly mounted on the side of the connecting plate 6 facing the gear ring 11 , and a light beam emitter 12 is fixedly mounted on the side of the gear ring 11 facing the connecting plate 6 . The connecting plate 6 is welded to the base plate 31 .

[0042] When wire cutting is required, the rack 2 drives the gear ring 11 to rotate, and the gear ring 11 drives the wire drum 1 to rotate, so that the beam receiver 61 is aligned with the beam emitter 12. After the beam receiver 61 receives the light emitted by the beam emitter 12, the clamping assembly 3 clamps the wire, and the cutter 5 cuts the wire.

[0043] The cutter 5 is provided with a through slot 51 along the length direction, and a strip-shaped protrusion is provided on the side of the slide plate 7 close to the cutter 5. The strip-shaped protrusion is slidably matched with the through slot 51, and the protrusions of the two slide plates 7 do not contact. A half gear 53 is welded at the end of the cutter 5, and a vertical roller 54 is welded at the center of the half gear 53. The roller 54 is driven to rotate by a motor, so that the cutter 5 rotates to cut the wire.

[0044] In summary, the tool anti-hooking mechanism of the sock thread cutting machine sets up a clamping assembly 3 and a tool 5 between two thread drums 1, and the clamping piece 4 clamps the thread through the cooperation of the large spring 35, the second motor 37 and the steel wire 36, and then the thread cutting area is tightened by the synchronous operation of the motor 1 331, so as to prevent the thread from being loosened and affecting the cutting of the tool 5.

[0045] In addition, the cutter 5 is slidably matched with two slide plates 7 along the length direction, and the slide bar 71 and the small spring 72 cooperate to make the paddle 8 at the front end of the slide plate 7 always contact the cutter 5, and the paddle 8 cleans the surface of the cutter 5, thereby preventing the wire from being hooked on the cutter 5 after cutting. The paddle 8 has a grinding stone 81, and the grinding stone 81 grinds the edge of the cutter 5 during the movement of the paddle 8, thereby preventing the cutter 5 from becoming blunt due to long-term use.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
