Description

Technical Field

[0001] This utility model relates to the technical field of meltblown fabric production equipment, and in particular to a meltblown fabric winding machine. Background Technology

[0002] Meltblown fabric is mainly made of polypropylene. It has a loose structure with many pores and good wrinkle resistance. It has a unique capillary structure. The ultrafine fibers of the capillary structure increase the number of fibers and surface area per unit area, which makes meltblown fabric have good filtration, shielding, heat insulation and oil absorption properties. The production of meltblown fabric mainly involves hot air jetting the raw material and extruding hot polypropylene from the fine holes of the spinneret nozzle, making it extend into a fibrous shape. Then it is gathered on the conveyor belt and forms a fiber web based on its self-fusion property.

[0003] After the meltblown fabric is formed, it needs to be collected and rolled into rolls. In order to ensure the quality of the rolled meltblown fabric, the tension of the winding needs to be limited and kept constant to ensure that the meltblown fabric is wound with a constant tension force. In this way, the wound meltblown fabric is relatively compact. However, the tension force required for winding is different when producing meltblown fabric of different thicknesses. In view of this technical problem, this application proposes a meltblown fabric winding machine. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a meltblown fabric winding machine. Before winding, the connecting block can be pushed to raise it so that the meltblown fabric passes between two guide rollers. Subsequently, the connecting block falls back under gravity to clamp and guide the meltblown fabric. This machine is suitable for winding meltblown fabrics of different thicknesses. At the same time, the fixed block three is driven to move up and down by an electric push rod. In conjunction with the tension roller, the tension on the meltblown fabric of different thicknesses can be changed, making it more compact during winding.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A meltblown fabric winding machine includes a base, with support blocks fixedly connected to the left and right sides of the top of the base. Connecting blocks are connected to the left and right ends of the support blocks via adjusting components.

A rotating shaft is rotatably connected to the inner wall of each fixing seat, and an installation component is provided on the inner wall of the rotating shaft.

[0007] Furthermore, the adjustment component includes a first fixed block fixedly connected to both the left and right ends of the support block, a telescopic cylinder fixedly connected to the top of each first fixed block, and a second fixed block fixedly connected to the top of each telescopic cylinder.

[0021] 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.

[0022] Reference Figure 1-3 An embodiment of this utility model provides a meltblown fabric winding machine, including a base 1. Support blocks 2 are fixedly connected to the left and right sides of the top of the base 1. Connecting blocks 6 are connected to the left and right ends of the support blocks 2 through an adjustment component. The adjustment component includes a first fixed block 3 fixedly connected to the left and right ends of the support blocks 2. A telescopic cylinder 4 is fixedly connected to the top of the first fixed block 3. A second fixed block 5 is fixedly connected to the top of the telescopic cylinder 4. The opposite end of the second fixed block 5 is fixedly connected to the outward end of the connecting block 6. The bottom end of the connecting block 6 is set at the top of the support block 2. Guide rollers 7 are rotatably connected to the inner walls of the support block 2 and the connecting block 6. Electric push rods 10 are fixedly connected to the front and rear sides of the top of the base 1. A third fixed block 9 is fixedly connected to the driving end of the electric push rod 10. A tensioning roller 8 is rotatably connected to the inner wall of the third fixed block 9.

[0023] Specifically, before winding, the connecting block 6 can be pushed to raise it so that the meltblown fabric passes between the two guide rollers 7. Then the connecting block 6 falls back under gravity to clamp and guide the meltblown fabric. This method is suitable for winding meltblown fabrics of different thicknesses. At the same time, the electric push rod 10 drives the fixed block 9 to move up and down. In conjunction with the tension roller 8, the tension on the meltblown fabric of different thicknesses can be changed, making it tighter during winding.

[0024] A heat dissipation assembly is provided at the top center of the base 1. The heat dissipation assembly includes a heat dissipation box 11 fixedly connected to the top center of the base 1. A barrier net 12 is fixedly connected to the inner wall of the heat dissipation box 11. Multiple mounting seats 16 are fixedly connected to the bottom inner wall of the heat dissipation box 11. Fans 17 are provided on the inner wall of each mounting seat 16. Two fixed seats 13 are fixedly connected to the top right side of the base 1. Rotating shafts 19 are rotatably connected to the inner wall of each fixed seat 13. A drive motor 14 is fixedly connected to the front end of the front fixed seat 13. The front end of the front rotating shaft 19 is fixedly connected to the drive end of the drive motor 14. An installation assembly is provided on the inner wall of the rotating shaft 19. The installation assembly includes a take-up roller 18 located on the inner wall of the rotating shaft 19. A handwheel 15 is threadedly connected to the front side of the outer wall of the take-up roller 18. A limit ring 21 is fixedly connected to the rear side of the outer wall of the take-up roller 18. Fixing bolts 20 are threadedly connected to the inner walls of both the front and rear ends of the take-up roller 18. The outer walls of the fixing bolts 20 are threadedly connected to the inner wall of the rotating shaft 19.

[0025] Specifically, during the winding process, the fan 17 inside the heat sink 11 cools the freshly produced meltblown fabric, allowing it to be transported directly after winding. The barrier net 12 on the heat sink 11 protects the fan 17 from foreign objects entering the heat sink 11 and causing damage. The fixing bolts 20 used to fix the take-up roller 18 can be removed using a tool, and then the handwheel 15 can be turned to remove the take-up roller 18 for replacement. The limiting ring 21 on the take-up roller 18 limits the position of the take-up drum, preventing it from shifting and failing to wind properly. It also facilitates the replacement of the take-up drum on the take-up roller 18, making it convenient to use.

[0026] Working principle: In use, first lift the connecting block 6 to allow the meltblown fabric to pass between the two guide rollers 7. Then, the connecting block 6 will fall back under the action of gravity to clamp and guide the meltblown fabric. Then, fix the free end of the meltblown fabric to the take-up drum on the take-up roller 18. Then, drive the fixing block 3 9 to move up and down through the electric push rod 10 to adjust the tension of the meltblown fabric. Start the drive motor 14 to drive the rotating shaft 19 to rotate and drive the take-up roller 18 to rotate, so that the meltblown fabric is rolled onto the take-up drum. During the winding process, the fan 17 inside the heat dissipation box 11 will also cool the meltblown fabric, so that the meltblown fabric can be directly transported after winding. After winding, use tools to remove the fixing bolt 20 from the rotating shaft 19 and the take-up roller 18. The take-up roller 18 can be directly removed from the rotating shaft 19. Then, turn the handwheel 15 on the surface of the take-up roller 18 to directly remove the wound meltblown fabric and replace it with a new take-up drum machine for winding.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
