[0002] A circular loom is an industrial machine used to weave tubular fabric. It works by using a number of spindles on a warp frame, using a specified number of warp yarns based on the desired fabric width and tape width. Before entering the circular loom, the warp yarns are spun by a warp frame, creating a cross-slit. The weft shuttle then moves in a circular motion through the warp yarns, ultimately weaving the tubular fabric.

[0003] At present, a Chinese patent with authorization announcement number CN209516802U discloses a heat dissipation motor, including a casing, a front end cover, a front bearing, a rotating shaft, a base, a rear cover, a rear end cover, a ventilation pipe, a ventilation hole, a rear bearing, a middle bearing, a fan, a rear cover, a rotor and a stator. The casing is arranged on the base, the front end cover is arranged on the left side of the casing, the front bearing is arranged in the front end cover, the rear side of the casing is the rear end cover, the middle bearing is arranged on the rear end cover, the upper end of the rotating shaft is arranged in the front bearing and the rear bearing, the rotating shaft passes through the interior of the casing, the rotor is arranged on the rotating shaft, the rotor is arranged in the stator, the stator is arranged on the inner wall of the casing, multiple ventilation holes are provided in the rear end cover, multiple ventilation pipes are provided on the right side of the rear end cover, the ventilation pipes are located on the right side of the ventilation holes, and the ventilation pipes and the ventilation holes are connected to each other.

[0004] This type of heat dissipation motor has a simple structure, but in actual production, the end away from the ventilation hole has almost no heat dissipation due to slow air circulation, and is prone to overheating and damage during long-term operation. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a heat dissipation motor for a circular loom, which improves the heat dissipation performance so as to achieve the purpose of not being easily damaged during long-term operation.

[0006] In order to solve the above technical problems, the technical solution of the utility model is: a circular loom heat dissipation motor, including a fixed shaft, a fixed frame, a coil, a magnet, a shell, a front cover and a rear cover, the fixed frame is connected to the fixed shaft, the coil is wound on the fixed frame, the fixed shaft is rotatably connected to the front cover and the rear cover, the front cover and the rear cover are respectively connected to the two ends of the shell, the magnet is fixed on the inner wall of the shell and corresponds to the coil, the front cover is provided with a front ventilation hole, the rear cover is provided with a rear ventilation hole, the fixed frame is provided with a connecting hole, and the fixed shaft is provided with a wire hole.

[0007] To implement the above technical solution, the fixed shaft is fixed, the shell is connected to other equipment, and the wires are connected to the coil through the wire hole. After the wires are energized, the shell rotates along the axis of the fixed shaft, and wind can pass through the front ventilation holes, connection holes and rear ventilation holes, thereby directly dissipating heat to the inside of the motor, thereby meeting the requirements of long-term operation.

[0008] As a preferred solution of the present invention, there is a first dustproof structure between the front end cover and the fixing frame, and the first dustproof structure includes a first dustproof ring and a second dustproof ring. The first dustproof ring is fixed on the inner wall of the front end cover, and the second dustproof ring is fixed on the side wall of the fixing frame. The first dustproof ring is close to the second dustproof ring, and a first gap is formed between the first dustproof ring and the second dustproof ring.

[0009] To implement the above technical solution, during the rotation of the shell, the first dustproof ring is close to the second dustproof ring, so that dust is not easily entered into the first gap, thereby achieving a dust-proof effect. In addition, during the high-speed rotation of the shell, part of the heat can be discharged from the first gap to improve the heat dissipation.

[0010] As a preferred solution of the present invention, there is a second dustproof structure between the rear end cover and the fixing frame, the second dustproof structure includes a third dustproof ring and a fourth dustproof ring, the third dustproof ring is fixed on the inner wall of the rear end cover, the fourth dustproof ring is fixed on the side of the fixing frame facing away from the second dustproof ring, the third dustproof ring is close to the fourth dustproof ring and a second gap is formed between the third dustproof ring and the fourth dustproof ring.

[0011] To implement the above technical solution, during the rotation of the shell, the third dustproof ring is close to the fourth dustproof ring, so that dust is not easily entered into the second gap, thereby achieving a dust-proof effect. In addition, during the high-speed rotation of the shell, part of the heat can be discharged from the second gap to improve the heat dissipation.

[0012] As a preferred solution of the present invention, a front bearing is arranged between the fixed shaft and the front end cover, a front guard plate is fixedly connected to the front end cover, the inner wall of the front guard plate is close to the fixed shaft, and the side wall of the front guard plate is close to the side wall of the front bearing.

[0013] By implementing the above technical solution, when wind passes through the motor, part of the dust in the air is blocked by the front guard plate, making it difficult for the dust to get stuck in the front bearing, so that the front bearing can rotate smoothly for a long time.

[0014] As a preferred solution of the present invention, the front end cover is connected to a front connecting ring on the side facing away from the front guard plate, the fixed shaft is connected to a front protective sleeve, the front protective sleeve is close to the front bearing and is sleeved on the outside of the front connecting ring, and the front bearing is located in the space surrounded by the front guard plate, the front connecting ring and the front protective sleeve.

[0015] By implementing the above technical solution, dust is not easily able to enter the interior of the front bearing from either the front side or the rear side of the front end cover, thereby enabling the front bearing to operate stably for a long time.

[0016] As a preferred solution of the present invention, a rear bearing is provided between the fixed shaft and the rear end cover, a rear guard plate is fixedly connected to the rear end cover, the inner wall of the rear guard plate is close to the fixed shaft, and the side wall of the rear guard plate is close to the side wall of the rear bearing.

[0017] By implementing the above technical solution, when wind passes through the motor, part of the dust in the air is blocked by the rear guard plate, making it difficult for the dust to get stuck in the rear bearing, so that the rear bearing can rotate smoothly for a long time.

[0018] As a preferred solution of the present invention, the rear end cover is connected to a rear connecting ring on the side facing away from the rear guard plate, the fixed shaft is connected to a rear protective sleeve, the rear protective sleeve is close to the rear bearing and is sleeved on the outside of the rear connecting ring, and the rear bearing is located in the space surrounded by the rear guard plate, the rear connecting ring and the rear protective sleeve.

[0019] By implementing the above technical solution, dust is not easily able to enter the interior of the rear bearing from either the front or rear side of the rear end cover, thereby enabling the rear bearing to operate stably for a long time.

[0020] As a preferred solution of the present invention, a plurality of reinforcing rods are fixedly connected to the fixing frame, the length direction of the reinforcing rods is parallel to the radial direction of the fixing frame, and the reinforcing rods are located between two adjacent connecting holes.

[0021] The implementation of the above technical solution improves the structural strength of the fixing frame. BRIEF DESCRIPTION OF THE DRAWINGS
