[0002] In the sock manufacturing industry, the sock knitting machine's serged disc is a key component, and its quality and durability directly impact sock production efficiency and product quality. Traditionally, serged disc production methods rely on manual operation or simple mechanization, resulting in low production efficiency and inconsistent quality. In particular, the quenching process for the serged disc, due to complex operations and inaccurate temperature control, often leads to insufficient hardness and deformation, severely hindering the development of the sock manufacturing industry.

[0003] To improve the production efficiency and processing quality of sock machine sewing gear discs, the market urgently needs production equipment that can automate and precisely control the quenching process. However, most existing production equipment has problems such as complex structure, cumbersome operation, and high energy consumption, which cannot meet the requirements of efficient and high-quality production.

[0004] Therefore, it is very necessary to invent a high-efficiency production equipment for a sock machine sewing toothed disc. Utility Model Content

[0025] As attached Figure 1 To the attached Figure 4 As shown:

[0026] The utility model provides high-efficiency production equipment for the sewing tooth disc of a sock machine, comprising a quenching box 1, a support frame 2, an induction heating coil 3, an induction heater 4, a rotating inner expanding arm 5 and a downward-pressing rotary cylinder 6. The support frame 2 is fixedly installed on one side above the box body 11 of the quenching box 1, the induction heating coil 3 is arranged on the inner side of the support frame 2, the induction heating coil 3 is connected to the induction heater 4 fixedly installed on one side of the support frame 2, the induction heating coil 3 is located below the rotating inner expanding arm 5, and the rotating inner expanding arm 5 is fixed to the output end of the downward-pressing rotary cylinder 6 fixedly installed on the upper outside of the support frame 2.

[0027] Furthermore, the box body 11 of the quenching box 1 is firmly fixed to one end of the conveyor frame 7, and support legs 8 are respectively installed on both sides of the outside of the other end of the conveyor frame 7. This design not only ensures the stability of the quenching box 1, but also provides solid support for the conveying of the slit toothed disc through the conveyor frame 7.

[0028] Furthermore, two rotatably mounted conveyor rollers are mounted inside the conveyor frame 7, on which conveyor belts 10 are mounted. One of the conveyor rollers is tightly connected to the output end of a conveyor drive component 9 fixedly mounted outside the conveyor frame 7, so that the conveyor belt 10 can run smoothly under the drive of the drive component 9, thereby realizing the automatic conveying of the slit gear disc.

[0029] Furthermore, one end of the conveyor belt 10 is cleverly designed to be below one end of the rotating carrier plate 51 of the rotating inner expansion arm 5. This layout ensures that the slit toothed disc can be accurately grasped by the inner expansion structure (inner expansion head 52, drive head 53 and inner expansion cylinder 54) of the rotating inner expansion arm 5 during the conveying process.

[0030] Furthermore, the rotating inner expansion arm 5 also includes an inner expansion head 52, a drive head 53, and an inner expansion cylinder 54. The inner expansion heads 52 are divided into two groups, each consisting of several inner expansion heads 52, which are mounted at both ends below the rotating carrier plate 51. A drive head 53 is located between each group of inner expansion heads 52, and the drive head 53 is connected to the output end of the inner expansion cylinder 54 fixed at one end above the rotating carrier plate 51. This design allows the inner expansion heads 52 to flexibly expand under the drive of the inner expansion cylinder 54, thereby tightly clamping the slit gear disc.

[0031] Furthermore, the rotating carrier plate 51 has two lower ends provided with slots for mounting the inner expansion joints 52. These slots are equipped with springs. Thus, the inner expansion joints 52 are elastically mounted on the rotating carrier plate 51. This elastic mounting method not only increases the flexibility of the inner expansion joints 52 but also ensures that they maintain sufficient clamping force when clamping the slit toothed disc.

[0032] Furthermore, each inner expanding head 52 is provided with an inclined surface on its inner side, so that the inner sides of each set of inner expanding heads 52 collectively form a conical area. The driving head 53 is also designed with a conical head structure, corresponding to the conical area formed by each set of inner expanding heads 52. This design allows the driving head 53 to push the inner expanding heads 52 more smoothly and efficiently.

[0033] Furthermore, the quenching box 1 includes an electric slide rail 12, a hydraulic rod 13, a cross plate 14 and a driving rotating component 15. The electric slide rail 12 installed on the box body 11 is connected to the lower end of the hydraulic rod 13, the upper end of the hydraulic rod 13 is fixed to the cross plate 14, and the driving rotating component 15 is fixedly installed on the cross plate 14.

[0034] Furthermore, the output end of the driving rotating component 15 is connected to a supporting chassis 16, to which several positioning shafts 17 are fixedly mounted. These positioning shafts 17 are cleverly designed, allowing the slotted toothed disc to be positioned externally and always remain directly below the induction heating coil 3. This arrangement ensures that after the slotted toothed disc is released from the internal expansion structure, it falls precisely onto the positioning shafts 17 and is evenly heated during the quenching process, achieving the best quenching effect.

[0035] The operating principle is as follows: First, at the start of operation, the slit toothed disc is placed on the conveyor belt 10. The conveyor belt 10 is driven by the conveyor drive unit 9 and runs smoothly on two rotatably mounted conveyor rollers. The conveyor frame 7 provides solid support for the conveyor belt 10 and the slit toothed disc on it, while the support leg 8 at the other end of the conveyor frame 7 ensures the stability of the entire equipment.

[0036] Then, as the conveyor belt 10 moves, the slit toothed disc is conveyed below one end of the rotating carrier plate 51 of the rotating inner expansion arm 5. At this point, the downward-pressing rotary cylinder 6 begins to operate, its output end pushing the rotating inner expansion arm 5 and the rotating carrier plate 51 on it downward. The internal expansion structure of the rotating inner expansion arm 5 (including the internal expansion head 52, drive head 53, and internal expansion cylinder 54) begins to function. The internal expansion cylinder 54 drives the drive head 53 downward, which in turn pushes the internal expansion head 52 to slide within the chute and expand, tightly clamping the center hole of the slit toothed disc.

[0037] Next, the rotary cylinder 6 is pressed down to raise and reset the rotating inner expansion arm 5, and rotates the rotating inner expansion arm 5 so that the end with the slit toothed disc is directly above the induction heater 4. It then continues to descend and starts the induction heater 4. During this process, the other end of the rotating inner expansion arm 5 clamps the new slit toothed disc, and the slit toothed disc is quickly heated by the induction heating coil 3. Because the induction heating coil 3 is located below the rotating inner expansion arm 5 and the slit toothed disc is tightly clamped by the inner expansion structure, the heating process is very uniform and efficient.

[0038] After the heating is completed, the inner expansion cylinder 54 is reset, the heated slotted toothed disc falls off, and falls downward onto the positioning shaft 17 installed on the supporting chassis 16, and the downward rotation cylinder 6 works again, and the above steps are repeated.

[0039] During this process, the electric slide 12 and hydraulic rod 13 inside the quenching box 1 can start to work together. The electric slide 12 drives the hydraulic rod 13 and its upper cross plate 14 and the driving rotating component 15 to move to the appropriate position, and the hydraulic rod 13 further adjusts the height of the cross plate 14 so that the output end of the driving rotating component 15 is connected to the supporting chassis 16.

[0040] When all the positioning shafts 17 on the supporting chassis 16 have slit toothed discs and the heat treatment is completed, the electric slide rail 12 drives the hydraulic rod 13 and the cross plate 14 at its upper end and the driving rotating component 15 to move to the appropriate position, the hydraulic rod 13 drives the cross plate 14 to rise, and the supporting chassis 16 and the positioning shaft 17 will be separated from the box body 11, so that the slit toothed disc can be taken out.

[0041] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
