The push rod and the threaded sleeves are arranged in a one-to-one correspondence.

[0010] In a preferred embodiment of the present invention, the angles between adjacent through holes are the same, the centers of the cross sections of the plurality of through holes all fall on the same circle, and the through holes and the positioning grooves are arranged in a one-to-one correspondence.

The plurality of universal wheels are respectively arranged at each corner of the support body, and a discharge tray is installed at one end of the support body, and the discharge tray is arranged on one side of the guide hole.

[0014] In a preferred embodiment of the present invention, a sleeve is inserted into the through hole, the outer wall of the sleeve is in contact with the inner wall of the through hole, and the sleeve matches the inner diameter of the corresponding through hole.

[0015] Since the existing notches on the edge of the driving wheel are fixed, they cannot be well matched and pressed when facing steel wires of different diameters, resulting in poor contact and inability to perform wire feeding operations. For this reason, the following is a specific implementation plan of the adjustable wire feeding device for the spring machine according to the present application with reference to the accompanying drawings: In a preferred embodiment of the present invention, a main shaft is rotatably installed in the shell, the reduction motor is connected to the main shaft through a reduction gear set, a receiving groove is hollowly provided in the main shaft, a limiting slide groove is provided on the surface of the main shaft, two limiting slide grooves are provided, a first rack and a second rack are slidably engaged in the two limiting slide grooves respectively, a gear is rotatably installed in the accommodating groove, the first rack and the second rack are respectively meshed with the gear, and a knob for driving the gear to rotate is rotatably installed on the outer surface of the main shaft.

[0017] The driving wheel in the present scheme is composed of a left half wheel and a right half wheel, and a first inclined surface is provided on the edge of the left half wheel, and a second inclined surface is provided on the edge of the right half wheel. The first inclined surface and the second inclined surface are connected to each other to form a V-shaped groove, and the V-shaped groove cooperates with the pressure roller to clamp and compress the steel wire, and the worm is driven to rotate by rotating the worm, so that the worm wheel synchronously drives the gear to rotate, and the gear synchronously drives the first rack and the second rack to slide, so that the first rack and the second rack are close to or away from each other, thereby adjusting the spacing between the grooves on the edges of the left half wheel and the right half wheel, so as to realize the pressing and wire feeding of steel wires of different diameters, and adopts the meshing transmission of the worm wheel and the worm, so that the adjusted position between the first rack and the second rack is fixed and locked, so as to prevent the driving wheel from being pushed by external force to reverse the worm wheel, thereby achieving an effective locking effect and facilitating adjustment and use.

[0018] In a preferred embodiment of the present invention, the first rack and the second rack are arranged rotationally symmetrically with respect to the gear, the first rack and the second rack are arranged in parallel, and the knob is arranged outside the housing.

[0019] Since dust and impurities will adhere to the surface of the wire during the operation of the driving wheel, impurities will accumulate in the groove of the driving wheel, which will reduce the friction and cause the wire to slip. In severe cases, the wire will be separated from the groove of the driving wheel, making it impossible to perform the wire feeding operation. For this reason, the following is a specific implementation plan of the adjustable wire feeding device of the spring machine according to the present application with reference to the accompanying drawings: In a preferred embodiment of the present invention, the support body is rotatably mounted with a brush body, the brush body comprises a rotatably mounted rod body and a brush head mounted at the end of the rod body, the brush head contacts the inner wall of the V-shaped groove formed on the edge of the driving wheel, and the support body is mounted with a transmission mechanism for driving the rod body to rotate.

[0020] In a preferred embodiment of the present invention, the transmission mechanism includes a transmission shaft and a synchronous belt. The transmission shaft is rotatably installed at the bottom of the support body. A synchronous pulley A is coaxially fixed to one end of the transmission shaft, and a bevel gear A is coaxially fixed to the other end of the transmission shaft. A synchronous pulley B is coaxially fixed to the main shaft, and the synchronous pulley B is connected to the synchronous pulley A through the synchronous belt transmission. A bevel gear B is coaxially fixed to the rod body, and the bevel gear A is meshed with the bevel gear B.

[0021] A brush body in contact with the driving wheel slot is installed at the bottom of the support body. The driving wheel rotates so that the brush body can comprehensively clean the driving wheel slot. Since the brush body rotates synchronously with the driving wheel, the rotating brush body can clean the driving wheel. The synchronous rotation drive is adopted to make the cleaning more thorough. The rotation of the brush body rotates with the rotation of the driving wheel, and the power of the driving wheel is effectively used to achieve a self-cleaning effect. No manual maintenance and cleaning is required, which reduces the occurrence of wire feeding accidents and improves work efficiency.

[0022] During use, the cylinder may rotate due to accidental contact, causing the diameter of the through hole corresponding to the guide hole to change, resulting in the inability to feed the wire. For this reason, the following is a specific implementation plan of the adjustable wire feeding device of the spring machine according to the present application with reference to the accompanying drawings: In a preferred embodiment of the present invention, the support body is slidably connected with a slider, the slider is arranged at the lower end of the positioning ball, a pull ring is fixed to one end of the slider, the other end of the slider is connected to a tension spring, and one end of the tension spring is connected to the support body.

[0023] A slider is arranged at the lower end of the positioning ball, and the upper surface of the slider contacts the lower surface of the spring sheet, so that the spring sheet cannot be deformed. The positioning ball is stuck in the positioning groove, so that the cylinder is locked and cannot rotate, thereby achieving a locking effect and avoiding accidents caused by accidental contact or misoperation. By pulling the pull ring, the slider slides away from the bottom of the spring sheet, and at the same time, the tension spring is stretched to store energy, so that the positioning ball can push the spring sheet to deform, thereby adjusting the rotation of the cylinder. After the adjustment is completed, the pull ring is released, and under the elastic force of the tension spring, the slider slides to the bottom of the spring sheet to achieve a self-locking effect. An inclined surface is provided at one end of the slider to facilitate the slider to slide to the bottom of the spring sheet and avoid getting stuck.

[0024] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through the practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

When in use, the cylinder 310 is rotated so that the through holes 311 with corresponding apertures are coaxially aligned with the guide hole 101, and the wire can be fed and used without disassembly and replacement, which is convenient and quick to operate, thereby improving work efficiency. The spring material is clamped at the junction of the driving wheel 510 and the pressure roller 530. The driving wheel 510 is driven to rotate by the reduction motor 550, thereby pushing the spring material and synchronously driving the pressure roller 530 to rotate, thereby realizing the feeding operation. By setting the positioning groove 331 and engaging with the positioning ball 350, the rotation angle can be positioned and locked when the cylinder 310 is rotated. Every time it rotates a certain angle, the positioning ball 350 will fall into the positioning groove 331. At the same time, the through hole 311 will also be synchronously coaxially aligned with the guide hole 101, which is convenient for threading and feeding operations.

[0032] In addition, the adjustable wire feeding device of the spring machine according to the embodiment of the present application also has the following additional technical features: In a specific embodiment of the present invention, a shell 150 is fixed to the support body 100 , the shell 150 is provided with an inspection port, the inspection port is equipped with an inspection cover, and the driving assembly 500 is disposed in the shell 150 .

The push rod 575 and the threaded sleeves 573 are arranged in a one-to-one correspondence.

[0036] In a specific embodiment of the present invention, the angles between adjacent through holes 311 are the same, the centers of the cross sections of the through holes 311 all fall on the same circle, and the through holes 311 and the positioning grooves 331 are arranged in a one-to-one correspondence.

[0037] In a specific embodiment of the present invention, a universal wheel 103 is installed at the bottom of the support body 100, and a plurality of universal wheels 103 are provided. The plurality of universal wheels 103 are respectively arranged at each corner of the support body 100, and a discharge tray 110 is installed at one end of the support body 100, and the discharge tray 110 is arranged on one side of the guide hole 101.

[0038] Specifically, if Figure 1-Figure 2 As shown, in a specific embodiment of the present invention, the support body 100 is rotatably mounted with a rotating shaft 130 , a driving wheel 131 is coaxially fixed to the rotating shaft 130 , a driven wheel 313 is coaxially fixed to the cylinder 310 , and the driving wheel 131 is meshed with the driven wheel 313 .

[0039] In a specific embodiment of the present invention, a rotating rod is coaxially fixed to the cylinder 310 , and the end of the rotating rod is rotatably mounted on the upper end of the support body 100 via a bearing seat. A handle 133 is mounted on one end of the rotating shaft 130 .

[0040] In a specific embodiment of the present invention, a sleeve is inserted into the through hole 311 , the outer wall of the sleeve is in contact with the inner wall of the through hole 311 , and the sleeve matches the inner diameter of the corresponding through hole 311 .

[0041] Since the existing notch on the edge of the driving wheel 510 is fixed, it cannot be well matched and pressed when facing steel wires of different diameters, resulting in poor contact and inability to perform wire feeding operations. For this reason, the following is a specific implementation scheme of the adjustable wire feeding device for a spring machine according to the present application with reference to the accompanying drawings: Specifically, if Figure 3-Figure 9 As shown, in a specific embodiment of the present invention, a main shaft 590 is rotatably installed in the shell 150, and the reduction motor 550 is connected to the main shaft 590 through a reduction gear set. The main shaft 590 is hollow with a receiving groove, and a limiting slide groove is provided on the surface of the main shaft 590. There are two limiting slide grooves, and the first rack 591 and the second rack 592 are respectively slidably engaged in the two limiting slide grooves. A gear 593 is rotatably installed in the receiving groove, and the first rack 591 and the second rack 592 are respectively meshed with the gear 593. A knob 596 for driving the gear 593 to rotate is rotatably installed on the outer surface of the main shaft 590.

[0042] In a specific embodiment of the present invention, the driving wheel 510 includes a left half wheel 511 and a right half wheel 512, and the left half wheel 511 and the right half wheel 512 are slidably mounted on the surface of the main shaft 590, the left half wheel 511 is fixed to the first rack 591, and the right half wheel 512 is fixed to the second rack 592; a worm wheel 594 is coaxially fixed to the gear 593, and the worm wheel 594 is meshed with a worm 595, and one end of the worm 595 is coaxially fixed to the knob 596.

[0043] The driving wheel 510 in this solution is composed of a left half wheel 511 and a right half wheel 512, and the edge of the left half wheel 511 is provided with a first inclined surface, and the edge of the right half wheel 512 is provided with a second inclined surface, and the first inclined surface and the second inclined surface are connected to each other to form a V-shaped groove, and the V-shaped groove cooperates with the pressure roller 530 to clamp the pressing wire, and the worm 595 is driven to rotate by rotating the worm 595, so that the worm wheel 594 synchronously drives the gear 593 to rotate, and the gear 593 synchronously drives the first rack 591 and the second rack 593 to rotate. 92 slides, causing the first rack 591 and the second rack 592 to move closer to or farther away from each other, thereby adjusting the spacing between the edge grooves of the left half wheel 511 and the right half wheel 512, and realizing the pressing and feeding of steel wires of different diameters. The worm wheel 594 and the worm 595 are engaged and driven, so that the adjusted position between the first rack 591 and the second rack 592 is fixed and locked, preventing the driving wheel 510 from being pushed by external force to reverse the worm wheel 594, thereby achieving an effective locking effect and facilitating adjustment and use.

[0044] In a specific embodiment of the present invention, the first rack 591 and the second rack 592 are rotationally symmetrically arranged with respect to the gear 593 , the first rack 591 and the second rack 592 are arranged in parallel, and the knob 596 is arranged outside the shell 150 .

[0045] Since dust and impurities will adhere to the surface of the steel wire during the operation of the driving wheel 510, impurities will accumulate in the groove of the driving wheel 510 where the wire is clamped, which may reduce the friction force and cause the wire to slip. In severe cases, the steel wire may be separated from the clamping groove of the driving wheel 510, making it impossible to perform the wire feeding operation. For this reason, the following is a specific implementation plan of the adjustable wire feeding device for a spring machine according to the present application with reference to the accompanying drawings: Specifically, if Figure 2-Figure 5 As shown, in a specific embodiment of the present invention, the support body 100 is rotatably mounted with a brush body 170, the brush body 170 includes a rotatably arranged rod body and a brush head mounted on the end of the rod body, the brush head is in contact with the inner wall of the V-shaped groove opened on the edge of the driving wheel 510, and the support body 100 is installed with a transmission mechanism 190 for driving the rod body to rotate.

[0046] In a specific embodiment of the present invention, the transmission mechanism 190 includes a transmission shaft 191 and a synchronous belt 193.

A synchronous pulley B195 is coaxially fixed to the main shaft 590, and the synchronous pulley B195 is connected to the synchronous pulley A194 through the synchronous belt 193. A bevel gear B197 is coaxially fixed to the rod body, and the bevel gear A196 is meshed with the bevel gear B197.

[0047] A brush body 170 in contact with the slot of the driving wheel 510 is installed at the bottom of the support body 100. When the driving wheel 510 rotates, the brush body 170 completely cleans the slot of the driving wheel 510. Since the brush body 170 rotates synchronously with the driving wheel 510, the rotating brush body 170 cleans the driving wheel 510. The synchronous rotation drive is adopted to make the cleaning more thorough. The rotation of the brush body 170 rotates with the rotation of the driving wheel 510, and the power of the driving wheel 510 is effectively used to achieve a self-cleaning effect. No manual maintenance and cleaning is required, which reduces the occurrence of wire feeding accidents and improves work efficiency.

[0048] The cylinder 310 may rotate due to accidental collision during use, so that the diameter of the through hole 311 corresponding to the guide hole 101 changes, resulting in the inability to feed the wire. For this reason, the following is a specific implementation plan of the adjustable wire feeding device of the spring machine according to the present application with reference to the accompanying drawings: Specifically, if Figure 2-Figure 4As shown, in a specific embodiment of the present invention, the support body 100 is slidably connected to a slider 180, the slider 180 is arranged at the lower end of the positioning ball 350, a pull ring 181 is fixed to one end of the slider 180, and the other end of the slider 180 is connected to a tension spring 183, and one end of the tension spring 183 is connected to the support body 100.

[0049] A slider 180 is provided at the lower end of the positioning ball 350, and the upper surface of the slider 180 contacts the lower surface of the spring 351, so that the spring 351 cannot be deformed. The positioning ball 350 is stuck in the positioning groove 331, so that the cylinder 310 is locked and cannot rotate, thereby achieving a locking effect and avoiding accidents caused by accidental contact or misoperation. By pulling the pull ring 181, the slider 180 slides away from the bottom of the spring 351, and at the same time, the tension spring 183 is stretched to store energy, so that the positioning ball 350 can push the spring 351 to deform, and then the rotation of the cylinder 310 can be adjusted. After the adjustment is completed, the pull ring 181 is released, and under the elastic force of the tension spring 183, the slider 180 slides to the bottom of the spring 351 to achieve a self-locking effect. One end of the slider 180 is provided with an inclined surface to facilitate the slider 180 to slide to the bottom of the spring 351 to avoid getting stuck.
