[0008] Working principle:

[0009] This device is a plastic multi-wedge pulley, mainly used to connect with the roller steel pipe, and drives the roller to rotate through the drive of the conveyor belt.

[0010] During production, the pulley of this application is integrally injection molded and uses a high-strength thermoplastic engineering plastic.

[0011] During installation, the bearings are first installed on both sides of the mounting through hole. Then, the connecting cylinder section and the roller steel pipe are connected. Specifically, the connecting cylinder section is sleeved inside the steel pipe and abuts against one side of the steel pipe through the retaining edge, and the steel pipe and the connecting cylinder section are fixed. After installation, the roller and pulley are installed together on the equipment, and the pulley groove on the pulley body is matched with the external conveyor belt to drive the pulley groove and the roller to rotate.

[0012] Beneficial effects achieved:

[0013] First, by setting the guardrails, the conveyor belt and rollers can be separated in area, effectively preventing the conveyor belt from contacting the rollers during driving, thus affecting the rotation speed of the rollers. Moreover, this separation can effectively reduce the noise emitted by the device during transportation.

[0014] Secondly, the connection cavity allows for reduced material usage while maintaining elastic support between the connecting cylinder section and the inner hole of the steel pipe, achieving an interference fit and improving the stability of the connection. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example:

[0021] Reference Figures 1 to 3The device is a plastic multi-wedge belt wheel, which comprises a wheel body 1, which is integrally injection molded by polyamide material, which has the advantages of good wear resistance, light weight and low noise.

[0022] As shown in Figure 3 , the shaft center of the wheel body 1 is provided with a mounting hole 2, and the two side openings of the mounting hole 2 are provided with countersunk heads. A plurality of reinforcing ribs 9 are uniformly arranged on the side wall of the mounting hole 2. The plurality of reinforcing ribs 9 are arranged along the axis of the wheel body 1, which can reduce the material consumption while maintaining the performance, thereby further reducing the production cost. The two sides of the mounting hole 2 are used for connecting the bearing. The plurality of reinforcing ribs 9 can also play a positioning role for the bearing.

[0023] As shown in Figure 1 and Figure 3 , the outer side wall of the wheel body 1 is provided with an annular ridge 3. A plurality of belt grooves 4 are arranged on the outer side wall of the wheel body 1 on one side of the ridge 3. The wheel body 1 is connected with the conveyor belt through the belt grooves 4. It is worth mentioning that the conveyor belt is a multi-wedge belt, which is arranged according to the requirements of "GBT 16588-2009 Belt transmission Industrial multi-wedge belt and belt wheel PH, PJ, PK, PL and PM type: size".
