Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology for circular knitting machine syringes, and in particular to a heat treatment device for large circular knitting machine syringes. Background Technology

[0002] The cylinder of a circular knitting machine is the core working component of the machine, and its structure and function directly affect the quality of the fabric and production efficiency.

[0003] The cylinder of a large circular knitting machine needs to withstand the friction and impact of the knitting needles during high-speed operation. By quenching and low-temperature tempering, a high-hardness martensitic structure can be formed, which significantly extends the service life.

[0004] The existing low-temperature tempering process for large circular knitting machine syringes is carried out in an oven. Since the oven is set up independently, after the low-temperature tempering process is completed, the syringes need to be taken out of the oven and then cooled, which is a rather cumbersome process. Utility Model Content

[0005] The purpose of this invention is to provide a heat treatment device for large circular knitting machine syringes in order to solve the above-mentioned problems.

[0006] The technical solution of this utility model is implemented as follows:

[0007] This utility model provides a heat treatment device for large circular knitting machine syringes. Its structure includes a moving platform and a heat treatment unit. A sliding positioning groove is horizontally provided on the moving platform, and a transmission screw is rotatably installed within the sliding positioning groove. The heat treatment unit is slidably mounted on the upper surface of the moving platform, and its bottom is threadedly connected to the transmission screw. The heat treatment unit includes a workpiece positioning seat and a heat treatment sealing cover connected to the top surface of the workpiece positioning seat for heat treatment. The workpiece positioning seat includes a seat body, a positioning groove at the center of the top surface of the seat body, and several syringe placement grooves at the edge of the top surface of the seat body. A limiting groove is vertically provided on the inner wall of the positioning groove. The heat treatment sealing cover includes a cover body adapted to the seat body and several spiral heating tubes vertically connected to the bottom edge of the cover body. The spiral heating tubes are nested within the corresponding syringe placement grooves.

[0008] In the above technical solution, the mobile platform is connected to the cooling zone. After the syringe quenching is completed, several syringes are placed in several syringe placement slots. The heat treatment sealing cover is placed on the workpiece positioning seat by manual or robotic arm. During this process, the spiral heating tube is nested inside the syringe. When the spiral heating tube heats up, it will perform a low-temperature tempering process on the syringe. After the process is completed, the heat treatment sealing cover is removed by manual or robotic arm. The cover is then moved to the cooling zone by the drive screw for direct cooling, which effectively simplifies the process.

[0010] In one embodiment, to improve the compactness of the structure, several syringe placement slots are arranged in a circular array with the positioning slot as the center.

[0011] In one embodiment, in order to enable the spiral heating tubes to perform heating operations, the base is provided with a power input device connected to several spiral heating tubes to conduct current into the resistance wires inside the spiral heating tubes to generate heat. A power supply cable interface adapted to the power input device is provided on one side of the base.

[0012] In one embodiment, a handle is provided on the top surface of the seat to facilitate the removal of the seat by the staff.
