DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further describes the present utility model in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model.

[0022] Refer to Figures 1 to 4 , the present utility model provides a loom drum support mechanism, including a base 1 and an auxiliary component 2. The base 1 is arranged on the ground or other supporting surfaces, brackets 11 are arranged at both ends of the top surface of the base 1, and an auxiliary component 2 is arranged above the base 1.

[0023] Refer to Figures 1 to 4, the auxiliary component 2 includes a lifting seat 21 and a driving shaft 22. The lifting seats 21 are all slidably connected to the support 11. At both ends of the bottom surface of the lifting seat 21, bottom convex plates 211 are provided. Below the lifting seats 21, driving shafts 22 are rotatably provided. The two ends of the driving shaft 22 are respectively rotatably connected to the two bottom convex plates 211 on the same lifting seat 21. A first belt is provided between the two driving shafts 22. One end of one of the driving shafts 22 is connected to the output shaft of the driving member 221. The driving member 221 is provided on the bottom convex plate 211, and the driving member 221 can drive the driving shaft 22 to rotate reciprocally. Sleeve shafts 23 are rotatably sleeved on the driving shafts 22. Positive ratchets are provided on the side walls at one end of the sleeve shafts 23. The positive ratchets, the sleeve shafts 23 and the driving shafts 22 are concentric. A positively rotatable positive pawl is rotatably provided on the driving shaft 22. When the positive ratchet cooperates with the positive pawl, the driving shaft 22 can drive the sleeve shaft 23 to rotate unidirectionally. Two driving blocks 24 are provided on each of the sleeve shafts 23. The driving blocks 24 are all slidably connected to the bottom surface of the lifting seat 21. Two circulation grooves with opposite directions are provided on each of the sleeve shafts 23. The two circulation grooves are in one-to-one correspondence with the driving blocks 24 (that is, through holes for the sleeve shafts 23 to pass through are provided on the driving blocks 24, and guide posts for cooperating with the circulation grooves are provided on the inner side walls of the through holes).

[0024] See Figures 1 to 4 , on the side of the driving block 24 far from the center of the sleeve shaft 23, an outer driven block 25 is elastically connected. A first elastic member is provided between the adjacent driving block 24 and the outer driven block 25. The outer driven blocks 25 are all slidably connected to the bottom surface of the lifting seat 21. Lifting connecting rods 251 are rotatably provided between the outer driven blocks 25 and the base 1 (that is, one end of the lifting connecting rod 251 is rotatably connected to the top surface of the base 1, and the other end of the lifting connecting rod 251 is rotatably connected to the outer driven block 25). When the two outer driven blocks 25 on the same sleeve shaft 23 move away from each other, the lifting seat 21 rises. On the side of the driving block 24 close to the center of the sleeve shaft 23, an inner driven block 26 is elastically connected. A second elastic member is provided between the adjacent inner driven block 26 and the driving block 24. The inner driven blocks 26 are all slidably connected to the bottom surface of the lifting seat 21. Clamping seats 27 are slidably provided on the side of the lifting seat 21 close to the center of the base 1. Clamping connecting rods 261 are rotatably provided between the inner driven blocks 26 and the clamping seats 27 (that is, one end of the clamping connecting rod 261 is rotatably connected to the inner driven block 26, and the other end of the clamping connecting rod 261 is rotatably connected to the clamping seat 27). When the two inner driven blocks 26 on the same sleeve shaft 23 move away from each other, the clamping seat 27 moves towards the direction close to the center of the base 1.

[0025] See Figures 1 to 4, at both ends of the top surface of the lifting seat 21, there are top convex plates 212. A driven shaft 28 is rotatably arranged above the lifting seat 21. A second belt is arranged between the driving shaft 22 and the driven shaft 28 on the same lifting seat 21. A first bevel gear 281 is rotatably arranged on the driven shaft 28. An anti-ratchet is arranged on the side wall of one side of the first bevel gear 281. The anti-ratchet, the first bevel gear 281 and the driven shaft 28 are concentric. The positive ratchet is in the opposite direction to the anti-ratchet. An anti-ratchet pawl that can rotate unidirectionally is rotatably arranged on the driven shaft 28. Rotary discs 271 are rotatably arranged on the clamping seats 27. Telescopic shafts 29 are arranged on the rotary discs 271. The telescopic shafts 29 each include an inner shaft and an outer shaft. The inner shaft is slidably sleeved inside the outer shaft. Fixed plates 213 for rotatably connecting the telescopic shafts 29 are arranged on the top surface of the lifting seat 21. A second bevel gear 291 meshing with the first bevel gear 281 is arranged on the telescopic shaft 29.

[0026] See Figures 1 to 4 , preferably, a cross beam 12 is connected to the top end of the bracket 11. A receiving groove is arranged on the bottom surface of the cross beam 12. A pressing plate 13 is slidably arranged in the receiving groove. A number of third elastic members are arranged between the pressing plate 13 and the top surface of the receiving groove. The pressing plate 13 can compact the fabric when winding the fabric, avoiding wrinkles on the fabric.

[0027] See Figures 1 to 4 , preferably, the first elastic member, the second elastic member and the third elastic member are all springs.

[0028] See Figures 1 to 4 , preferably, the driving member 221 is a rotary motor, which can provide sufficient power.

[0029] See Figures 1 to 4 , preferably, a frustum-shaped member 272 is arranged on one side of the rotary disc 271 close to the center of the base 1, which can not only improve the clamping stability of the device for the drum, but also make the device applicable to drums of different diameters.

[0030] In the implementation process of the present utility model: The user places the empty drum above the base 1, and then starts the driving member 221. The driving member 221 rotates forward. At this time, the positive ratchet wheel cooperates with the positive ratchet pawl, and the reverse ratchet wheel does not cooperate with the reverse ratchet pawl. The sleeve shaft 23 rotates, and the first bevel gear 281 does not rotate. The rotation of the sleeve shaft 23 drives the two active blocks 24 on the same sleeve shaft 23 to move away from each other. The active blocks 24 drive the two inner driven blocks 26 to move away synchronously. Under the action of the clamping connecting rod 261, the frustum member 272 is inserted into the drum (in this process, the lifting seat 21 will rise a small distance. As long as the distance between the frustum member 272 and the end of the drum is small, the rising distance of the lifting seat 21 can be ignored). During the process of the frustum member 272 clamping the drum, the lifting seat 21 drives the drum to rise. When the drum rises to the highest point of its movement range, the pressing plate 13 abuts against the side wall of the drum. At this time, the fabric is wound around the drum, and then the driving member 221 rotates in reverse. At this time, the sleeve shaft 23 does not rotate, and the first bevel gear 281 rotates, driving the turntable 271, the frustum member 272 and the drum to rotate, realizing the winding of the fabric. After the winding is completed, the driving member 221 rotates forward, and the two active blocks 24 on the same sleeve shaft 23 approach each other, sequentially realizing the lowering of the lifting seat 21 and the reset of the clamping seat 27.

[0031] The present utility model provides a loom drum support mechanism, and its beneficial effects are as follows:

[0032] 1. By setting the auxiliary component, it can not only automatically complete the clamping and lifting of the drum, but also drive the drum to rotate automatically, and only one power source is required for the above process. This not only improves the efficiency of fabric winding, but also reduces the manufacturing and use costs.

[0033] 2. By setting the movable pressing plate, it can compact the fabric, avoid wrinkles when the fabric is wound, and improve the fabric quality.

[0034] In summary, the beneficial effects of the present utility model are: it can automatically complete the clamping, lifting and rotation of the drum, and can also automatically compact the fabric, improve the efficiency of fabric winding, and ensure good product quality.

[0035] Of course, the present utility model can also have multiple embodiments. Without departing from the spirit and essence of the present utility model, those skilled in the art can make corresponding changes and deformations according to the present utility model, but these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present utility model.
