Description

Technical Field

[0001] This utility model relates to the technical field of transmission mechanisms for large circular knitting machines, and in particular to a heat dissipation enhanced transmission mechanism for large circular knitting machines. Background Technology

[0002] The circular knitting machine disc is one of the core components of a circular knitting machine. A transmission mechanism is installed outside the circular knitting machine disc to drive its rotation. The circular knitting machine disc is used to install knitting needles or yarn guide devices.

[0003] The existing transmission mechanism connected to the circular knitting machine disc generates a lot of heat during operation due to the high relative sliding speed and high friction coefficient. Workers often need to set up a cooling mechanism outside the transmission mechanism. However, whether it is wind cooling or liquid cooling, the wind force or liquid dissipation will inevitably affect the knitting work. Utility Model Content

The drive positioning plate is located on the bottom surface of the transmission outer gear ring. The transmission gear is rotatably connected to the front of the top surface of the drive positioning plate and meshes with the transmission outer gear ring. The motor is located on the rear surface of the drive positioning plate, and its output end is connected to the transmission gear.

Compared with the existing technology, the spraying stroke is shortened to prevent the outward dissipation of cooling liquid from affecting the knitting work.

[0008] The specific heat dissipation process is as follows: the cooling liquid is introduced into the hollow positioning shaft through the cooling liquid conduit.

[0009] In one embodiment, for precise heat dissipation, the heat-dissipating sliding positioning assembly includes a hollow positioning shaft symmetrically rotatably mounted on the rear of the top surface of the drive positioning plate, a limiting wheel rotatably sleeved on the hollow positioning shaft, a heat dissipation positioning cover located at the end of the limiting wheel, and a heat dissipation hole located at the center of the heat dissipation positioning cover and communicating with the hollow positioning shaft. One end of the hollow positioning shaft is provided with an atomizing mesh plate adapted to the heat dissipation hole. The rear end face of the drive positioning plate is provided with a cooling liquid interface connected to the other end of the hollow positioning shaft. The bottom surface of the transmission outer gear ring is provided with a positioning ring that slides between the two limiting wheels.

[0010] In one embodiment, in order to reduce the frictional force of contact, the heat dissipation positioning cover contacts the bottom surface of the transmission outer gear ring, and the end face of the heat dissipation positioning cover in contact with the transmission outer gear ring has an arc-shaped smooth surface structure.

[0011] In one embodiment, for rotational positioning, an annular limiting groove is provided in the middle section of the hollow positioning shaft, and a positioning protrusion is provided on the inner ring of the limiting wheel to slide and engage with the annular limiting groove.

[0012] In one embodiment, a brake bracket is provided in the middle section of the top surface of the drive positioning plate to restrict the movement of the transmission external gear ring.

[0013] In one embodiment, in order to improve braking efficiency, the brake frame is provided with an electric push rod that contacts the top surface of the transmission outer gear ring.

[0014] In one embodiment, for the input of cooling liquid, a cooling liquid conduit is further included, which is threadedly and sealed to the cooling liquid interface.

[0015] The advantages or beneficial effects of the above technical solutions include at least the following:
