Description

Technical Field

[0001] This utility model relates to the field of pom-pom production equipment, and in particular to a novel pom-pom machine. Background Technology

[0002] In the production of pom-poms, the yarn bundles are first wound into a bundle and fed into the machine. Then, through cutting and rounding, they are transformed into neat, round pom-poms. In actual production, the diameter of the pom-poms needs to be changed according to user requirements. Changes in pom-pom specifications also alter the thickness of the input yarn bundles, necessitating adjustments to both the input and rounding mechanisms of the pom-pom machine.

[0003] The input mechanism of the existing fuzz ball machine includes two pressure rollers with gear meshing. When the distance between the pressure rollers changes, gears of different diameters need to be replaced, thus requiring multiple sets of gears of different diameters, which increases the equipment cost. The rounding mechanism includes a limiting plate with a limiting groove. The fixing pin for transferring the fuzz ball needs to move along the limiting groove to avoid collision with the machine. When the size of the fuzz ball changes, the height of the limiting plate also needs to be adjusted accordingly, making the operation of the equipment cumbersome in actual application. Utility Model Content

[0004] To solve the above problems, this utility model proposes a new type of pom-pom machine.

[0005] The technical solution adopted by this utility model is: a novel pom-pom machine, comprising...

A universal joint is hinged between the wheel axle located on the upper side and the pressure roller. The wheel axle located on the lower side and the pressure roller are fixedly connected.

[0008] A rounding mechanism includes a positioning frame, in which a rotating cutter is provided. The positioning frame is rotatably connected to the machine base. A height adjustment mechanism is provided between one end of the positioning frame and the machine base. The height adjustment mechanism is used to tilt the positioning frame toward the unloading mechanism.

[0009] Furthermore, the machine base is provided with a rotating shaft, and the bottom rear end of the positioning frame is provided with a rotating hole. The rotating shaft is rotatably connected to the rotating hole. The height adjustment mechanism includes a positioning shaft and an adjustment hole. The positioning shaft is fixedly connected to the machine base, and the adjustment hole is located at the bottom front end of the positioning frame. The positioning shaft is inserted and fixedly connected to the adjustment hole.

[0010] Furthermore, the adjusting hole is arc-shaped, and the end of the positioning shaft is provided with a positioning nut. The positioning nut is used to fix the position of the positioning shaft and the adjusting hole. Several support plates are fixedly provided on the machine base. The support plates are arranged on both sides of the bottom of the positioning frame. The positioning shaft and the rotating shaft are respectively provided on the support plates at the front and rear ends.

[0011] Furthermore, the support frame is provided with a first slider and a second slider, a first rotating rod is rotatably connected between the two first sliders, a second rotating rod is rotatably connected between the two second sliders, the pressure roller is fixed on the first rotating rod and the second rotating rod respectively, the first slider is connected to the end of the adjusting rod, and the universal joint is hinged between the first rotating rod and the wheel axle located on the upper side.

[0014] Compared with the prior art, this utility model has the following beneficial effects:

[0015] In this invention, when the adjusting rod drives the upper pressure roller to move upward, the distance between the pressure roller and the axle increases. This distance can be filled by stretching the universal joint rod. Users do not need to replace the transmission wheel, and the axle and pressure roller can rotate synchronously. This saves equipment costs by saving the reserve of transmission wheels of different sizes. After the positioning frame is tilted, the height difference between it and the fixed pin in the feeding mechanism increases significantly, which can effectively prevent the fixed pin from colliding with the positioning frame. Therefore, there is no need to install a limit plate. During subsequent adjustments, only the height change of the feeding mechanism needs to be controlled, which reduces the difficulty of subsequent equipment adjustments. Attached Figure Description

[0025] 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.

[0026] This utility model proposes a novel pom-pom machine, including a machine base 1, see reference. Figure 1 The machine base 1 is equipped with a power source 11, a cutting mechanism 12 and a feeding mechanism 13. The above mechanisms are the same as those in the prior art. For the specific structure and working principle, please refer to Chinese utility patent CN223199096U A fuzz ball rounding machine.

[0027] The feeding mechanism 2 is used to feed the wire harness into the cutting mechanism 12, see [reference]. Figure 3 The system includes a positioning plate 21 fixed on the machine base 1 and two support frames 22. Two pressure rollers 23 are provided between the two support frames 22. The two pressure rollers 23 can rotate freely. Either pressure roller 23 is connected to the power source 11. An adjusting rod 24 is provided between the support frame 22 and the upper pressure roller 23. The adjusting rod 24 can drive the upper pressure roller 23 to move, so as to adjust the distance between the two pressure rollers 23 to adapt to specific production needs. The positioning plate 21 is provided with two meshing transmission wheels 25. The transmission wheels 25 are provided with axles 251. The upper axle 251 and its corresponding upper pressure roller 23 are hinged with a universal joint rod 26. The lower axle 251 and its corresponding lower pressure roller 23 are fixedly connected. The power source 11 drives one pressure roller 23 to rotate and drives the other pressure roller 23 to rotate synchronously through the transmission wheels 25.

[0028] Rounding mechanism 3, see reference Figure 4 The system includes a positioning frame 31, in which a rotating cutter 32 is provided. The rotating cutter 32 is driven by a separate motor. The positioning frame 31 is rotatably connected to the machine base 1. A height adjustment mechanism is provided between one end of the positioning frame 31 and the machine base 1. Through the height adjustment mechanism, the positioning frame 31 can be tilted toward the unloading mechanism 13.

[0029] In this equipment, when the adjusting rod 24 moves the upper pressure roller 23 upward, the distance between the pressure roller 23 and the axle 251 increases. This distance can be filled by stretching the universal joint 26. Users do not need to replace the drive wheel 25 to achieve synchronous rotation of the axle 251 and the pressure roller 23, thus saving equipment costs by eliminating the need for spare drive wheels 25 of different sizes. Figure 2 As shown, in the rounding mechanism 3, the tilting of the positioning frame 31 significantly increases the height difference between it and the fixed pin in the feeding mechanism 13, which can effectively prevent the fixed pin from colliding with the positioning frame 31. Therefore, there is no need to install a limit plate. During subsequent adjustments, only the height change of the feeding mechanism 13 needs to be controlled, which reduces the difficulty of subsequent equipment adjustments.

[0030] See Figure 4The machine base 1 is equipped with a rotating shaft 14, and the bottom rear end of the positioning frame 31 is provided with a rotating hole. The rotating shaft 14 is rotatably connected to the rotating hole, and the positioning frame 31 rotates around the rotating shaft 14. The height adjustment mechanism includes a positioning shaft 15 and an adjustment hole 311. The positioning shaft 15 is fixedly connected to the machine base 1, and the adjustment hole 311 is located at the bottom front end of the positioning frame 31. The adjustment hole 311 can be a plurality of through holes arranged in an arc shape, or it can be a direct arc-shaped through hole. The positioning shaft 15 changes the deflection angle of the positioning frame 31 by inserting into the adjustment hole 311 at different positions or sliding along the arc-shaped adjustment hole 311. A positioning accessory can be configured at the end of the positioning shaft 15 to keep the positioning frame 31 in a fixed position after the position is adjusted.

[0031] See Figure 4 In this embodiment, the adjustment hole 311 is arc-shaped, and the end of the positioning shaft 15 is provided with a positioning nut 151. After the positioning shaft 15 slides into place along the adjustment hole 311, the user tightens the positioning nut 151 to keep the position of the positioning shaft 15 and the positioning frame 31 fixed. A plurality of support plates 16 are fixedly provided on the machine base 1. The support plates are arranged on both sides of the bottom of the positioning frame 31. The positioning shaft 15 and the rotating shaft 14 are respectively provided on the support plates 16 at the front and rear. The support plates 16 can lift the positioning frame 31 away from the surface of the machine base 1, thereby facilitating the deflection of the positioning frame 31.

[0032] See Figure 3 The support frame 22 is provided with a first slider 221 and a second slider 222. A first rotating rod 223 is rotatably connected between the two first sliders 221, and a second rotating rod 224 is rotatably connected between the two second sliders 222. Bearings can be installed inside the sliders, and the ends of the two rotating rods pass through the bearings to ensure smooth rotation of the two rotating rods. The pressure roller 23 is fixed on the first rotating rod 223 and the second rotating rod 224 respectively. The first slider 221 is connected to the end of the adjusting rod 24. The universal joint 26 is hinged between the first rotating rod 223 and the wheel axle 251 located on the upper side.

[0033] See Figure 5 The universal joint 26 includes a left connector 261 and a right connector 262. The left connector 261 is hinged to the axle 251, and the right connector 262 is hinged to the first rotating rod 223. The left connector 261 is provided with a connecting spline 263, and the right connector 262 is provided with a spline hole 264. The connecting spline 263 is inserted into the spline hole 264. When the first slider 221 moves upward, the connecting spline 263 extends out of the spline hole 264 to fill the gap between the first rotating rod 223 and its corresponding axle 251, so as to ensure the synchronous rotation of the first rotating rod 223 and its corresponding axle 251.

[0034] Specifically, the support frame 22 has a threaded hole at its top, and the adjusting rod 24 is a screw rod that passes through the threaded hole. The first slider 221 is rotatably connected to the bottom end of the adjusting rod 24. A bearing can be installed on the first slider 221, and the bottom end of the adjusting rod 24 is inserted into the bearing. When the adjusting rod 24 rotates in the threaded hole to achieve lifting and lowering, the first slider 221 can be lifted and lowered accordingly. The support frame 22 has a guide boss 225, and guide grooves are provided on both sides of the first slider 221. The guide grooves and the guide boss 225 are engaged to ensure the stability of the sliding direction of the first slider 221.

[0035] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
