Description

Technical Field

[0001] This utility model relates to the field of pom-pom processing equipment, and in particular to a roller feeding mechanism for a pom-pom machine. Background Technology

[0002] In the production of pom-poms, the yarn bundles used as raw materials are wound into bundles by a bundling mechanism and then conveyed to the processing mechanism behind them by a conveying mechanism. The conveying mechanism consists of two pressure rollers, and gears are fixed on the rotating shafts of the pressure rollers. Power transmission is achieved through the meshing of the two gears.

[0003] To accommodate the production of fuzz balls of different specifications, one of the pressure rollers needs to be able to move up and down for adjustment. However, after each adjustment, the gap between the two gears will also change. The change in the gear meshing point will not only affect the transmission effect, but also accelerate the wear of the gear teeth. Therefore, users can only prepare multiple sets of gears for replacement, which not only increases the equipment cost, but also makes the equipment adjustment operation very cumbersome.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model proposes a roller feeding mechanism for a pom-pom machine, see reference. Figure 3 It includes a positioning plate 3 and two positioning frames 1 spaced apart. Both the positioning plate 3 and the positioning frames 1 are fixed on the base of the pompom machine. See reference. Figure 1 The positioning frame 1 is provided with a first positioning block 11 and a second positioning block 12. The first positioning block 11 is fixed in position with the positioning frame 1, and the second positioning block 12 is slidably connected to the positioning frame 1. A first synchronous rod 13 is rotatably provided between the two first positioning blocks 11, and a second synchronous rod 14 is rotatably provided between the two second positioning blocks 12. One end of the first synchronous rod 13 is connected to a power component 2, which can drive the first synchronous rod 13 to rotate. Synchronous rollers 15 are respectively passed through the first synchronous rod 13 and the second synchronous rod 14. The bundled wires move forward under the action of the two synchronous rollers 15. The positioning frame 1 is provided with an adjusting rod 16, which is used to adjust the height of the second positioning block 12.

[0025] Positioning plate 3, see Figure 1 , 2The positioning plate 3 is rotatably connected to a first synchronous gear 31 and a second synchronous gear 32. The first synchronous gear 31 is provided with a first transmission rod 311 fixedly connected to the first synchronous rod 13. The second synchronous gear 32 is provided with a second transmission rod 321. A universal joint rod 4 is hinged between the second transmission rod 321 and the second synchronous rod 14.

[0026] When the second positioning block 12 moves upward via the adjusting rod 16, the spline connection part in the universal joint 4 extends out. When the second positioning block 12 moves downward, the spline connection part in the universal joint 4 retracts. During the adjustment process, the change in the distance between the second transmission rod 321 and the second synchronous rod 14 is filled by the universal joint 4. Even when tilted, the universal joint 4 can still achieve synchronous rotation between the second transmission rod 321 and the second synchronous rod 14, ensuring stable power transmission.

[0027] See Figure 4 The universal joint 4 includes a left connector 41 and a right connector 42. The left connector 41 is hinged to the second transmission rod 321, and the right connector 42 is hinged to the second synchronizing rod 14. The left connector 41 is provided with a connecting spline 411, and the right connector 42 is provided with a spline hole 421. The connecting spline 411 is inserted into the spline hole 421.

[0028] See Figure 1 The first positioning block 11 is provided with a first rotating bearing 111, and the first synchronizing rod 13 passes through the two first rotating bearings 111. The second positioning block 12 is provided with a second rotating bearing 121, and the second synchronizing rod 14 passes through the two second rotating bearings 121. By setting the rotating bearings, the rotation of the two synchronizing rods can be made smoother.

[0029] See Figure 2 The power assembly 2 includes a motor 21, two transmission gears 22 and a synchronous belt 23. The transmission gears 22 are respectively fixed to the end of the first synchronous rod 13 and the output shaft of the motor 21. The synchronous belt 23 is sleeved on the two transmission gears 22, thereby realizing the transmission of power.

[0030] See Figure 1 , 2The positioning frame 1 has a threaded hole at its top, and the adjusting rod 16 is a screw that passes through the threaded hole. The user can rotate the adjusting rod 16 to move it up and down. The second positioning block 12 is rotatably connected to the bottom end of the adjusting rod 16. Specifically, a bearing can be set on the second positioning block 12, and the bottom end of the adjusting rod 16 is connected to the bearing to achieve the rotatable connection between the second positioning block 12 and the adjusting rod 16. The positioning frame 1 has a guide boss 17, and the second positioning block 12 has guide grooves on both sides. The guide grooves are fitted with the guide boss 17 to ensure the stability of the movement direction of the second positioning block 12.

All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
