Description

Technical Field

[0001] The utility model relates to the technical field of automatic packing, in particular to an automatic packing device for roving bales. Background Technique

[0002] Roving is finer yarn spun from coarser yarn, mainly used for weaving or spinning. The roving process is the last process in spinning production. It spins the coarser yarn into roving with a certain tex, meeting quality standards or customer requirements, for use in twisting, weaving, knitting, etc. It has the characteristics of being soft, shiny, smooth to the touch, light in weight, and good in air permeability, and is used to make light and thin clothes and fabrics, such as silk, spun silk and other textiles. After production, roving is usually packed in bags in the form of roving bales.

[0003] In the prior art, as disclosed in Chinese Patent CN217918672U, "an automatic packing device for roving bales", it includes a first transport rack, a second transport rack, a third transport rack and a stabilizing device. The second transport rack is arranged on one side of the first transport rack, the third transport rack is arranged on one side of the second transport rack. A bagging machine is arranged on the surface of the first transport rack, a push rod is arranged on the surface of the second transport rack, and two bag-supporting blocks are arranged on the surface of the second transport rack. The stabilizing device is arranged on the surface of the bag-supporting block, and the stabilizing device includes a hollow block which is fixedly connected to the surface of the bag-supporting block. A clamping plate is slidably connected to the inner wall of the hollow block, and a round hole is opened on the surface of the hollow block.

Detailed implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The technical solution provided by the present invention is as follows: As Figures 1-3 shown, in this embodiment, an automatic packing device for fine yarn bundles includes a pusher table 1 and a conveying table 2. The top end of the pusher table 1 is fixedly connected with a mounting frame 3. The top end of the mounting frame 3 is fixedly connected with a lifting cylinder 4. The telescopic end of the lifting cylinder 4 penetrates through the top end of the mounting frame 3 and is fixedly connected with a connecting frame 5. The inside of the connecting frame 5 is slidably connected with an adjusting frame 6. Both the top end and the bottom end of the adjusting frame 6 are respectively provided with two square through-holes 7. Two driven rods 8 are respectively slidably connected inside the four square through-holes 7. A connecting rod 9 is rotatably connected to the inner sides of the two driven rods 8. The other ends of the two connecting rods 9 are rotatably connected to a fixed column 10. The top end of the fixed column 10 is fixedly connected with the bottom end of the connecting frame 5. A centering plate 12 is fixedly connected to one side of the two driven rods 8 and at the lower edge position. Rollers 13 are fixedly connected to the bottom ends of the two driven rods 8. Among them, by setting the connecting rod 9, the two driven rods 8 can be driven to move during the movement of the fixed column 10. By setting the rollers 13, the movement of the driven rods 8 during centering is more convenient, and the friction with the surface of the pusher table 1 is reduced.

[0023] As Figure 1 and Figure 4As shown in the figure, one end of the material pushing table 1 is fixedly connected to one end of the conveying table 2. The top of the conveying table 2 is fixedly connected with a mounting frame 16. Inside the top surface of the mounting frame 16, a rotating gear 17 is rotatably connected. Two driven racks 18 are meshed on the outer surface of the rotating gear 17. One end of each of the two driven racks 18 is fixedly connected with a bag supporting plate 19. The tops of the two bag supporting plates 19 are slidably arranged on the inner top surface of the mounting frame 16. One side of each of the two bag supporting plates 19 is fixedly connected with a movable frame 20. Inside each of the two movable frames 20, a clamping plate 21 is slidably connected. One side of each of the two clamping plates 21 is fixedly connected with a pressing rod 22. One end of each of the two pressing rods 22 respectively penetrates through one side wall inside each of the two movable frames 20. The outer surfaces of the two pressing rods 22 are both sleeved with second return springs 23. One end of each of the two second return springs 23 is fixedly connected with one side of each of the two movable frames 20. The top of the rotating gear 17 penetrates through the inner top surface of the mounting frame 16 and is drivingly connected with a positive and negative motor 26. The outer surface of the positive and negative motor 26 is fixedly connected with the top of the mounting frame 16. By setting the rotating gear 17, the two driven racks 18 can be driven to move simultaneously, realizing the effect of expanding the bag supporting plates 19. By setting the pressing rods 22, they can contact the inner side plates of the mounting frame 16 during the process of the bag supporting plates 19 supporting the bag and enable the clamping plates 21 to move inside the movable frames 20 to clamp and fix the cloth bag during the subsequent movement of the bag supporting plates 19.

[0024] As Figure 4 shown in the figure, four positioning grooves 24 are penetrated and opened on the inner top surface of the mounting frame 16. Two positioning blocks 25 are fixedly connected to the tops of the two bag supporting plates 19. The outer surfaces of the four positioning blocks 25 are respectively slidably connected to the interiors of the four positioning grooves 24. By setting the positioning grooves 24 and the positioning blocks 25, the bag supporting plates 19 can be positioned to prevent them from skewing during the movement and improve the stability during bag supporting.

[0025] As Figure 4 shown in the figure, two limiting blocks 27 are fixedly connected to the inner top surface of the mounting frame 16. The interiors of the two limiting blocks 27 are respectively slidably connected to the outer surfaces of the two driven racks 18. By setting the limiting blocks 27, the driven racks 18 can be positioned to improve the meshing degree between them and the rotating gear 17.

[0026] As Figure 2 and Figure 3 shown in the figure, a first return spring 11 is sleeved on the outer surface of the fixed column 10. The top of the first return spring 11 is fixedly connected to the bottom end of the connecting frame 5. The bottom end of the first return spring 11 is fixedly connected to the top end of the adjusting frame 6. By setting the first return spring 11, the adjusting frame 6 can be reset.

[0027] As Figure 2 and Figure 3As shown, a limiting plate 14 is fixedly connected to the top ends of both driven rods 8, and a limiting ring 15 is fixedly connected to the outer surface of the fixed column 10. By providing the limiting plate 14, the skew of the driven rod 8 during movement can be prevented. By providing the limiting ring 15, the adjusting frame 6 can be positioned to prevent it from falling off the connecting frame 5.

[0028] As Figure 3 shown, limiting grooves 28 are provided on both inner side walls of the connecting frame 5, and positioning rods 29 are fixedly connected to both sides of the connecting frame 5. The outer surfaces of the two positioning rods 29 are respectively slidably connected to the interiors of the two limiting grooves 28. By providing the limiting grooves 28 and the positioning rods 29, the adjusting frame 6 can be positioned to improve its stability during movement.

[0029] The utility model provides an automatic packing device for roving bales, and the specific working principle is as follows:

[0030] After the roving bale is fed onto the pushing table 1, the lifting cylinder 4 presses down to drive the connecting frame 5 and the adjusting frame 6 to move downward. When the two rollers 13 contact the surface of the pushing table 1, the adjusting frame 6 stops moving. The connecting frame 5 continues to move under the thrust of the lifting cylinder 4 and pushes the fixed column 10 to move. During the movement of the fixed column 10, the connecting rod 9 is driven to move. The connecting rod 9 rotates and pulls the two driven rods 8 to contract in the square through hole 7, so that the two centering plates 12 approach each other to clamp and center the roving bale. During the centering of the roving bale, the positive and negative motor 26 drives the rotating gear 17 to move, so that the two driven racks 18 follow the movement and drive the two bag-supporting plates 19 to expand to open the cloth bag. During the bag-supporting process, the two pressing rods 22 contact the inner side walls of both sides of the mounting frame 16, and during the subsequent movement of the bag-supporting plate 19, the clamping plate 21 moves in the movable frame 20 to squeeze the outer side of the cloth bag to stably fix the cloth bag. Then, the pushing mechanism on the pushing table 1 pushes the roving bale into the cloth bag for packing.
