Description

Technical Field

[0001] This utility model relates to a tape feeding device for a non-woven tape winding machine, belonging to the field of DC motor rotor production technology. Background Technology

[0002] Currently, there are two methods for binding and fixing the end windings of the generator rotor using non-woven belts.

[0003] Method 1: The winding of the non-woven tape is mostly done manually. During manual winding, the force is uneven and the winding is not firm, which can easily lead to generator failure. In addition, it is time-consuming and labor-intensive, increasing labor costs.

[0004] Method Two: A horizontal lathe and chuck are used to fix the generator rotor. The tape winding machine's feeder is located on one side of the horizontal lathe, serving as the tape winding machine. A crane sling is used to lift the rotor from the winding table onto the horizontal lathe. The sling is then removed, and the rotor is clamped onto the large horizontal lathe. The machine is started, and one end of the tape is wound around the rotor coil. The power to the tape binding machine is then turned on, and the tape is bound to the other end of the rotor coil.

[0005] Current technology is not comprehensive and has the following drawbacks: 1. When binding the rotor, there are requirements not only for the number of binding turns but also for the tightness of the binding. Manual binding can only meet the number of turns requirement, and the tightness cannot be controlled. 2. The existing tape feeding shaft is not detachably installed between the first and second rotating shafts, which makes it difficult to facilitate later maintenance or component replacement.

[0006] To solve one of the above problems, there is an urgent need for a tape handling device for a non-woven tape winding machine. Utility Model Content

[0007] Based on the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to achieve the detachable installation of the tape feeding shaft between the first rotating shaft and the second rotating shaft, so as to facilitate later maintenance or component replacement, and by adding a second brake assembly and a first brake assembly, the tension can be easily adjusted as needed during the non-woven tape binding process. Therefore, a tape feeding device for a non-woven tape winding machine is provided.

[0008] The non-woven tape winding machine of this utility model includes a tape feeding device comprising a vertical mounting frame, a horizontal mounting frame vertically mounted at the bottom end of the vertical mounting frame, and a non-woven tape wound on a tape feeding shaft. The device is characterized by further including a lower tensioning pulley and an upper tensioning pulley rotatably mounted on the vertical mounting frame. The lower tensioning pulley and the upper tensioning pulley are parallel to each other and spaced apart. The free end of the non-woven tape passes sequentially around the upper tensioning pulley and the lower tensioning pulley. A mounting plate is mounted on one side of the vertical mounting frame. The mounting plate is provided with a first brake assembly cooperating with the lower tensioning pulley and a second brake assembly cooperating with the upper tensioning pulley. A first rotating shaft and a second rotating shaft are detachably connected to both ends of the tape feeding shaft. The first rotating shaft and the second rotating shaft are rotatably mounted on the horizontal mounting frame via bearing seat assemblies C and D, respectively.

[0009] The non-woven belt on the unloading shaft passes sequentially around the lower tensioning pulley and the upper tensioning pulley before winding onto the motor rotor. The rotation of the motor rotor pulls the non-woven belt. This application, by adding a second brake assembly and a first brake assembly, allows for convenient adjustment of the tension force as needed during the non-woven belt binding process. Furthermore, the unloading shaft is detachably installed between the first and second rotating shafts, reducing on-site installation difficulty. The bolt connection method enables quick assembly and disassembly, facilitating later maintenance or component replacement.

[0010] Preferably, the axle A of the lower tensioning pulley is rotatably mounted on the mounting plate via a bearing housing assembly A. The first brake assembly includes a brake belt A and a lower brake wheel. The lower brake wheel is mounted on one end of the axle A and is coaxial with the axle A. The brake belt A partially surrounds the lower brake wheel. A fixing block A is provided at one end of the brake belt A and is fixed to the mounting plate. A belt adjustment mechanism A is provided at one end of the brake belt A and is mounted on the mounting plate.

[0011] Preferably, the belt adjusting mechanism A includes a screw that passes through the mounting plate, one end of the screw being connected to the brake belt A, a sliding retaining ring being sleeved on the screw, a compression spring being sleeved on the screw between the sliding retaining ring and the mounting plate, and a wing nut being threaded onto the screw, the wing nut abutting against the sliding retaining ring.

[0012] The position of the wing nut on the screw can be adjusted. For example, adjusting the wing nut away from the mounting plate can reduce the friction between the brake belt A and the lower brake wheel. Under external force, the lower brake wheel will rotate more easily relative to the brake belt A, thus reducing the tension of the non-woven strap. Conversely, adjusting the wing nut closer to the mounting plate can increase the friction between the brake belt A and the lower brake wheel, thus increasing the tension of the non-woven strap and reducing the difficulty of on-site adjustments.

[0013] Preferably, the brake belt A is further provided with a wear-resistant layer A, which is located between the brake belt A and the lower brake wheel.

[0014] Preferably, the axle B of the tensioning pulley is rotatably mounted on the mounting plate via a bearing housing assembly B. The second brake assembly includes a brake belt B and an upper brake wheel. The upper brake wheel is mounted on one end of the axle B and is coaxial with the axle B. The brake belt B partially surrounds the upper brake wheel. One end of the brake belt B is fixed to a fixing block A. A belt adjustment mechanism B is provided at one end of the brake belt B, and the belt adjustment mechanism B is mounted on the mounting plate.

[0015] Preferably, the belt adjusting mechanism B has the same structure and the same adjustment method as the belt adjusting mechanism A.

[0016] Preferably, the brake belt B is further provided with a wear-resistant layer B, which is located between the brake belt B and the upper brake wheel.

[0017] Preferably, the two ends of the tape feeding shaft are respectively provided with a flat shaft A and a flat shaft B. The first rotating shaft is provided with a slot A that is inserted and connected to the flat shaft A. A connecting bolt A passes through the slot A and the flat shaft A to connect the tape feeding shaft to the first rotating shaft. One end of the second rotating shaft is provided with a slot B that is inserted and connected to the flat shaft B. A connecting bolt B passes through the slot B and the flat shaft B to connect the tape feeding shaft to the second rotating shaft.

[0018] The unwinding shaft can be removed from the first and second rotating shafts by removing connecting bolts A and B. After the non-woven tape is wound onto the unwinding shaft to form a roll, the unwinding shaft can be installed between the first and second rotating shafts for reuse, reducing the difficulty of on-site installation. The bolt connection method enables quick assembly and disassembly, which is convenient for later maintenance or component replacement.

[0019] Preferably, a fixing ring is provided on the unwinding shaft, and the non-woven tape is wound on the unwinding shaft to form a roll, with the roll close to one side of the fixing ring.

[0020] Preferably, both the lower tensioning pulley and the upper tensioning pulley are provided with concave non-woven belt winding guide grooves.

The lower tensioning pulley 3 and the upper tensioning pulley 4 are parallel to each other and spaced apart. The free end of the non-woven tape passes around the upper tensioning pulley 4 and the lower tensioning pulley 3 in sequence. A mounting plate 25 is mounted on one side of the vertical mounting frame 1. The mounting plate 25 is provided with a first brake assembly that cooperates with the lower tensioning pulley 3 and a second brake assembly that cooperates with the upper tensioning pulley 4. A first rotating shaft 14 and a second rotating shaft 18 are detachably connected to both ends of the tape feeding shaft 9. The first rotating shaft 14 and the second rotating shaft 18 are rotatably mounted on the horizontal mounting frame 2 through bearing seat assemblies C12 and D13, respectively.

[0033] Reference Figure 4 The non-woven belt 23 on the unloading shaft 9 passes sequentially around the lower tensioning pulley 3 and the upper tensioning pulley 4 before winding onto the motor rotor. The rotation of the motor rotor pulls the non-woven belt. This application, by adding a second brake assembly and a first brake assembly, allows for convenient adjustment of the tension force as needed during the non-woven belt binding process. Furthermore, the unloading shaft 9 is detachably installed between the first rotating shaft 14 and the second rotating shaft 18, reducing on-site installation difficulty. The bolt connection method enables quick assembly and disassembly, facilitating later maintenance or component replacement.

[0034] Example 1, as Figure 1-2As shown, the tape feeding device of the non-woven tape winding machine includes a vertical mounting frame 1, a horizontal mounting frame 2 vertically mounted at the bottom end of the vertical mounting frame 1, a non-woven tape 23 wound on a tape feeding shaft 9, and a lower tensioning pulley 3 and an upper tensioning pulley 4 rotatably mounted on the vertical mounting frame 1. The lower tensioning pulley 3 and the upper tensioning pulley 4 are parallel to each other and spaced apart. The free end of the non-woven tape passes around the upper tensioning pulley 4 and the lower tensioning pulley 3 in sequence. A mounting plate 25 is mounted on one side of the vertical mounting frame 1. The mounting plate 25 is provided with a first brake assembly that cooperates with the lower tensioning pulley 3 and a second brake assembly that cooperates with the upper tensioning pulley 4. A first rotating shaft 14 and a second rotating shaft 18 are detachably connected to both ends of the tape feeding shaft 9. The first rotating shaft 14 and the second rotating shaft 18 are rotatably mounted on the horizontal mounting frame 2 through bearing seat assemblies C12 and D13, respectively.

[0035] Furthermore, referring to Figure 3 The axle A of the lower tensioning pulley 3 is rotatably mounted on the mounting plate 25 via the bearing seat assembly A.

A wing nut 29 is threaded onto the screw 26, and the wing nut 29 abuts against the sliding retaining ring 28.

[0037] The position of the wing nut 29 on the screw 26 can be adjusted. For example, adjusting the wing nut 29 away from the mounting plate 25 can reduce the friction between the brake belt A5 and the lower brake wheel 8. Under external force, the lower brake wheel 8 will rotate more easily relative to the brake belt A5, thus reducing the tension of the non-woven strap. Adjusting the wing nut 29 closer to the mounting plate 25 can increase the friction between the brake belt A5 and the lower brake wheel 8, thus increasing the tension of the non-woven strap and reducing the difficulty of on-site adjustment.

[0038] Furthermore, a wear-resistant layer A30 is provided on the brake belt A5, and the wear-resistant layer A30 is located between the brake belt A5 and the lower brake wheel 8.

After the non-woven tape 23 is wound around the tape-laying shaft 9 to form a tape roll, the tape-laying shaft 9 can be installed between the first rotating shaft 14 and the second rotating shaft 18 for reuse, reducing the difficulty of on-site installation.
