Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile equipment, in particular to a bobbin winder empty tube conveying auxiliary device. BACKGROUND

[0002] The bobbin winder is a device used in the textile industry to unwind yarn (or fiber) from a bobbin (such as a roving tube, a spun yarn tube) and re-wind it into a specified specification bobbin, widely used in wool spinning, cotton spinning, chemical fiber industry, etc.

[0003] During the operation of the bobbin winder, the recovery and conveying of the empty tube (yarn tube) is a key link in the continuous production of yarn. Its main function is to move the used empty tube from the bobbin winder spindle area, and transport the empty tube to the next station (such as cleaning, reuse or waste collection).

[0004] The traditional empty tube conveying system clamps and drags the empty tube through two counter-rotating triangular belts. The above technical solution has the following problems: 1. It is easy to cause empty tube conveying failure: machine vibration or friction force difference between new and old triangular belts causes empty tube deviation and falling off; 2. It needs to frequently adjust the distance and tension of the triangular belts to adapt to different yarn tube models. Therefore, the operator needs to monitor and adjust the parameters in real time, and the empty tube conveying system has a high failure rate. Conveying failure will cause the entire production line to be interrupted, affecting production efficiency. SUMMARY

[0005] In order to solve the problems of the prior art, the purpose of the present application is to provide a bobbin winder empty tube conveying auxiliary device, which can solve the problem of empty tube conveying failure caused by the poor precision and stability of the traditional triangular belt pulling system, thereby improving the empty tube conveying efficiency.

[0006] To achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0007] The application provides a bobbin winding machine empty tube conveying auxiliary device, which comprises two groups of conveying belt assemblies, a booster and a first compression spring.

[0008] As a preferred technical scheme, the bobbin winding machine empty tube conveying auxiliary device further comprises a second compression spring, the second transmission roller is connected with the second compression spring, and the second compression spring presses the second transmission roller towards the first transmission roller.

[0009] As a preferred technical scheme, the upper transmission roller at the empty tube outlet is a third transmission roller, the lower transmission roller at the empty tube outlet is a fourth transmission roller, and the bobbin winding machine empty tube conveying auxiliary device further comprises a third compression spring, the third transmission roller is connected with the third compression spring, and the third compression spring presses the third transmission roller towards the fourth transmission roller.

[0010] As a preferred technical scheme, the first compression spring is connected with an adjusting mechanism, the adjusting mechanism comprises a spring seat, a screw rod and a nut, the two ends of the first compression spring are fixedly connected with the spring seat and the first transmission roller respectively, the spring seat is fixedly connected with the nut, the screw rod is threadedly connected with the nut, and a through hole, through which the screw rod passes, is formed in the spring seat.

[0011] As a preferred technical scheme, anti-skid rubber layers are arranged on the outer surfaces of the two groups of conveying belts, the surface of the anti-skid rubber layer is distributed with staggered V-shaped grooves with a depth of 0.2-0.5 mm, and the groove spacing is 1-3 mm.

[0012] As a preferred technical scheme, the transmission roller driving mechanism and the booster roller shaft driving mechanism are both servo motors.

[0013] Compared with the prior art, the bobbin winding machine empty tube conveying auxiliary device has the following beneficial effects:

[0014] 1. The success rate of the air pipe transmission is improved: the air pipe is pushed into the air pipe entrance by the booster, and then the air pipe is clamped by the two parallel conveying belt clamping surfaces and conveyed forward, thereby improving the success rate of the air pipe transmission. Under the pressure of the first compression spring, the first transmission roller is pressed downward, which tightens the upper conveying belt and presses the clamping surface of the upper conveying belt toward the clamping surface of the lower conveying belt, thereby improving the clamping force of the air pipe transmission and avoiding the falling of the air pipe.

[0015] 2. Different yarn pipe models can be adapted: the position of the first transmission roller can be changed according to the diameter of the air pipe pushed into the air pipe entrance by setting the first compression spring, so that the size of the air pipe entrance can be adapted to different models of yarn pipes. Since the clamping surface of the upper conveying belt is pressed toward the clamping surface of the lower conveying belt, it is not necessary to adjust the distance between the two groups of conveying belts.

DETAILED DESCRIPTION

[0026] In order to make the personnel in the art better understand the scheme of the present application, the technical scheme in the specific embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application.

[0027] As Figure 1 shown, the present application provides a bobbin empty pipe conveying auxiliary device, which comprises two groups of conveyor belt assemblies 1, a booster 2 and a first compression spring 3.

[0028] The two groups of conveyor belt assemblies 1 are arranged above and below. Each group of conveyor belt assemblies 1 comprises a conveyor belt 11 and three drive rollers. The three drive rollers are arranged in parallel with each other and correspond to the three vertices of a triangle, and the conveyor belt 11 is annularly wound outside the three drive rollers.

[0029] At least one drive roller in each group of conveyor belt assemblies 1 is connected with a drive roller driving mechanism for driving the rotation of the drive roller. In the present application, the drive roller driving mechanism is a servo motor or the like, which can be connected with a speed reducer and then connected with the drive roller. Figure 1 The arrow indicates the running direction of the conveyor belt.

[0030] The opposite surfaces of the two conveyor belts 11 are clamping surfaces 111, and the two clamping surfaces 111 are parallel to each other. The front and rear ends of the two clamping surfaces 111 are respectively the empty pipe inlet 12 and the empty pipe outlet 13. The clamping surface 111 is basically a horizontal surface, so that the empty pipe can be supported and stably conveyed.

[0031] The upper drive roller at the empty pipe inlet 12 is set as the first drive roller 14, the lower drive roller at the empty pipe inlet 12 is set as the second drive roller 15, the upper drive roller at the empty pipe outlet 13 is set as the third drive roller 16, and the lower drive roller at the empty pipe outlet 13 is set as the fourth drive roller 17.

[0032] The first transmission roller 14 is connected with the first compression spring 3, and the first compression spring 3 presses the first transmission roller 14 towards the second transmission roller 15. Under the pressure of the first compression spring 3, the first transmission roller 14 is pressed downwards, on the one hand, so that the upper conveying belt 11 is tensioned, and on the other hand, so that the clamping surface 111 of the upper conveying belt 11 is pressed towards the clamping surface 111 of the lower conveying belt 11, the clamping force of the conveying of the empty tube is improved, so as to avoid the empty tube from falling. Therefore, the success rate of the conveying of the empty tube is improved. In addition, by arranging the first compression spring 3, the position of the first transmission roller 14 can be changed according to the diameter of the empty tube pushed into the empty tube inlet 12, so that the size of the empty tube inlet 12 can be adapted to different models of the bobbin. Since the clamping surface 111 of the upper conveying belt 11 is pressed towards the clamping surface 111 of the lower conveying belt 11, it is not necessary to adjust the distance between the two groups of conveying belts 11.

[0033] It should be noted that the size adjustment of the empty tube inlet 12 and the improvement of the clamping force of the conveying of the empty tube can also be realized by connecting the second transmission roller 15 with the first compression spring 3 instead of connecting the first transmission roller 14 with the first compression spring 3.

[0034] Since the diameter of the empty tube is larger than the size of the empty tube inlet 12, the booster 2 is arranged at the empty tube inlet 12 to push the empty tube into the empty tube inlet 12.

[0035] As shown in Figure 2 and Figure 3 , the booster 2 comprises a booster roller shaft 21 and a booster disc 22, and the booster disc 22 is fixedly installed on the booster roller shaft 21. The booster roller shaft 21 is connected with a booster roller shaft 21 driving mechanism for driving the booster roller shaft 21 to rotate, and the booster disc 22 pushes the empty tube into the empty tube inlet 12 in the process of rotation of the booster roller shaft 21. In the present application, the booster roller shaft 21 driving mechanism is a servo motor or the like.

[0036] As a preferred technical solution, the bobbin conveying auxiliary device of the winder further comprises a second compression spring 4, and the second transmission roller 15 is connected with the second compression spring 4, and the second compression spring 4 presses the second transmission roller 15 towards the first transmission roller 14. In the present application, the first transmission roller 14 is pressed downwards by the first compression spring 3 to tension the upper conveying belt 11, and the second transmission roller 15 is pressed upwards by the second compression spring 4 to tension the lower conveying belt.

[0037] As a preferred technical solution, the bobbin empty tube conveying auxiliary device further comprises a third compression spring 5, the third transmission roller 16 is connected with the third compression spring 5, and the third compression spring 5 presses the third transmission roller 16 towards the fourth transmission roller 17. By pressing the first transmission roller 14 and the third transmission roller 16 downwards through the first compression spring 3 and the third compression spring 5 respectively, the clamping surface 111 of the upper transmission belt is pressed downwards as a whole, so that the clamping force on the empty tube along the length direction of the clamping surface 111 is uniformly distributed. On the other hand, by arranging the third compression spring 5, the position of the third transmission roller 16 can be changed according to the diameter of the empty tube pushed into the empty tube outlet 13, so that the size of the empty tube outlet 13 can be adapted to different types of yarn tubes.

[0038] When the empty tube is sent out, the pushing force for sending out the empty tube is provided by the friction of the transmission belt 11 when the third transmission roller 16 and the fourth transmission roller 17 rotate, so preferably, the third transmission roller 16 and the fourth transmission roller 17 are connected with the transmission roller driving mechanism to improve the pushing force of the transmission belt 11 on the empty tube when the empty tube is sent out.

[0039] Figures 4-8 The overall process of empty tube conveying is shown.

[0040] As shown in Figure 9 As a preferred technical solution, the first compression spring 3 is connected with an adjusting mechanism 6. The adjusting mechanism 6 comprises a spring seat 61, a screw rod 62 and a nut 63, both ends of the first compression spring 3 are fixedly connected with the spring seat 61 and the first transmission roller 14 respectively, the spring seat 61 is fixedly connected with the nut 63, the screw rod 62 is threadedly connected with the nut 63, and the spring seat 61 is provided with a through hole through which the screw rod 62 passes. The screw rod 62 can be connected with a fixedly arranged rotating motor to drive the screw rod 62 to rotate. The rotation of the screw rod 62 drives the nut 63 to move along the screw rod 62, thereby adjusting the position of the spring seat 61 to adjust the pressing force on the empty tube when the empty tube enters the empty tube inlet 12.

[0041] It should be noted that the second compression spring 4 and the third compression spring 5 can also be connected with the above-mentioned adjusting mechanism 6.

[0042] As a preferred technical solution, anti-skid rubber layers are arranged on the outer surfaces of the two sets of transmission belts, the surfaces of the anti-skid rubber layers are distributed with staggered V-shaped grooves with a depth of 0.2-0.5 mm and a groove spacing of 1-3 mm, and the anti-skid rubber layers make the empty tube conveying more stable.
