Description

Technical Field

[0001] This utility model belongs to the technical field of braking devices for yarn conveying tracks, and particularly relates to a reverse braking device for inclined track chains. Background Technology

[0002] When yarn packages are transported in cages, the track needs to climb and descend slopes depending on the model of the winding machine or factory conditions. Due to gravity, the chain tends to reverse when climbing slopes and accelerates downwards when descending slopes. Both of these situations can damage the brake motor. Therefore, there is an urgent need for a device that can prevent the chain from reversing or the descending speed from accelerating when the cage is climbing or descending slopes. Utility Model Content

[0003] The purpose of this invention is to provide a reverse braking device for inclined track chains, which effectively solves the problem of brake motor damage caused by gravity during cage transport on inclined tracks.

The braking unit includes a rotating shaft assembly and a spring assembly for applying pressure to the rotating shaft assembly. The axis of the spring assembly is perpendicular to the track axis.

[0005] The rotating shaft assembly includes a bearing housing, a deep groove ball bearing, a one-way bearing, and a driven wheel. The long axis of the bearing housing is parallel to the track axis. The deep groove ball bearing and the one-way bearing are located at opposite ends of the bearing housing. A fixed shaft passes through the deep groove ball bearing, and the top end of the fixed shaft is fixedly connected to the frame.

[0006] The one-way bearing is located at the center of the driven wheel, the driven wheel is in contact with the track chain, a baffle is provided in the middle of the bearing seat, and the front end of the spring assembly abuts against the baffle.

[0007] Furthermore, the spring assembly includes a spring shaft, a rectangular spring, an adjusting sleeve for adjusting the preload of the rectangular spring, and a fixing ring. The rectangular spring is sleeved on the spring shaft, the spring shaft passes through the adjusting sleeve, the front end of the adjusting sleeve abuts against the rear end of the rectangular spring, the adjusting sleeve is fixed to the frame, the fixing ring is fixed to the tail end of the spring shaft, and the front end of the spring shaft abuts against the baffle.

[0009] Furthermore, the adjusting sleeve has external threads.

[0010] Compared with existing technologies, the beneficial technical effects of this utility model are as follows: By setting a one-way bearing and spring assembly, this utility model effectively prevents the driven wheel from reversing, thereby preventing the track chain from reversing and protecting the brake motor; through the cooperation of the spring assembly and the rotating shaft assembly, the pressure applied by the driven wheel to the track chain can be adjusted, preventing the chain from accelerating and protecting the brake motor.

Detailed Implementation

[0017] Example 1: Reverse braking device for inclined track chains, such as Figure 1 and Figure 2 As shown, it includes a frame 2 fixed to track 1 and two braking units symmetrically arranged with respect to the axis of track 1. Figure 3 As shown, the braking unit includes a rotating shaft assembly 31 and a spring assembly 32 for applying pressure to the rotating shaft assembly 31. The axis of the spring assembly 32 is perpendicular to the axis of the track 1. The frame 2 consists of a top wall, a bottom wall, and left and right side walls. The bottom wall has an opening, and the top wall of the frame 2 is located directly above the track 1.

[0018] like Figure 3 and Figure 5As shown, the rotating shaft assembly 31 includes a bearing housing 4, a deep groove ball bearing 5, a one-way bearing 6, and a driven wheel 7. The bearing housing 4 is approximately rectangular, and its long axis is parallel to the axis of the track 1. The deep groove ball bearing 5 and the one-way bearing 6 are located at the front and rear ends of the bearing housing 4, respectively. A fixed shaft 8 passes through the deep groove ball bearing 5, and the top end of the fixed shaft 8 is fixedly connected to the top wall of the frame 2. The one-way bearing 6 is located at the center of the driven wheel 7, and the driven wheel 7 contacts the chain of the track 1. The one-way bearing 6 prevents the driven wheel 7 from reversing. A baffle 9 is provided in the middle of the bearing housing 4, and the front end of the spring assembly 32 abuts against the baffle 9. By adjusting the spring assembly 32, the pressure applied by the spring assembly 32 to the baffle 9 can be adjusted, thereby driving the bearing housing 4 to rotate and realizing the adjustment of the pressure between the driven wheel 7 and the chain of the track 1.

[0019] like Figure 3 and Figure 4 As shown, the spring assembly 32 includes a spring shaft 10, a rectangular spring 11, an adjusting sleeve 12 for adjusting the preload of the rectangular spring 11, and a retaining ring 13. The spring shaft 10 passes through one side wall of the frame 2, and its front end abuts against the baffle 9. The rectangular spring 11 is sleeved on the spring shaft 10, which is inserted into the adjusting sleeve 12. The front end of the adjusting sleeve 12 abuts against the rear end of the rectangular spring 11. The adjusting sleeve 12 has external threads and is fixed to the frame 2. The retaining ring 13 is fixed to the tail end of the spring shaft 10 to prevent it from coming off. By rotating the adjusting sleeve 12, the preload of the rectangular spring 11 can be adjusted, thereby adjusting the pressure applied by the spring shaft 10 to the baffle 9, thus adjusting the pressure applied by the driven wheel 7 to the chain of the track 1.

[0020] The working principle of this utility model is as follows: When the yarn is being conveyed uphill, the track chain tends to reverse due to gravity. The one-way bearing 6 locks up, and combined with the pressure applied by the spring pressure shaft 10, it prevents the driven wheel 7 from reversing, thereby preventing the track chain from reversing and protecting the brake motor. When the yarn is being conveyed downhill, the preload of the rectangular spring 11 is adjusted by rotating the adjusting sleeve 12, which in turn adjusts the pressure applied by the spring pressure shaft 10 to the baffle 9. This adjusts the pressure applied by the driven wheel 7 to the track chain 1, preventing the chain from accelerating during downhill movement and protecting the brake motor.

[0021] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
