Description

Technical Field

[0001] The utility model relates to the technical field of tarpaulin production, in particular to a cloth stretching device for tarpaulin production. Background Art

[0002] A tarpaulin (or waterproof cloth) is a high-strength waterproof material with good toughness and softness. It is often used as canvas, oil painting cloth, polyester with polyurethane coating, or made into polyethylene plastics. Tarpaulins usually have strong grommets at the corners or edges for easy threading of ropes for tying, hanging, or covering.

[0003] When common tarpaulins are produced, in order to prevent them from becoming slack, a cloth stretching device is generally used to adjust the tension. Generally, the cloth stretching device makes the cloth bulge or dent through the up and down movement of the pressure roller, so as to stretch the cloth. However, since the distance of the roller pressing down or lifting up is large, the friction between the cloth and the roller is large when the cloth passes through the pressure roller, which easily causes the cloth to be worn, reducing the quality of tarpaulin production and not meeting the working requirements of the cloth stretching device. Moreover, since impurities will accumulate on the surface of the tarpaulin before winding, if the tarpaulin is wound, the impurities will make the surface of the tarpaulin uneven.

[0004] Therefore, for the improvement of the existing cloth stretching device for tarpaulin production, it is particularly important to design a new cloth stretching device for tarpaulin production to solve the above technical defects and improve the practicality of the overall cloth stretching device for tarpaulin production. Summary of the Utility Model

Through the overall design, the movable sleeve makes the two fixed sleeves approach each other, and the linkage rod is unfolded, thereby changing the diameter of the expansion plate, improving the speed and quality of cloth stretching. At the same time, the arc-shaped groove makes the extrusion rollers approach each other to flatten the tarpaulin, and the adhesive will remove the impurities, so as to solve the problems raised in the above background art.

[0021] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment:

[0023] Please refer to Figures 1 - 3 The present utility model provides a technical solution:

[0024] A cloth stretching device for tarpaulin production, including a frame 1, a bracket 2 fixedly connected to the back of the frame 1, a pay-off reel 3 rotatably connected inside the bracket 2, an extension plate 4 fixedly connected to the bottom end of the frame 1, a column 5 fixedly connected to the top of the extension plate 4, a bearing frame 6 fixedly connected to the outside of the extension plate 4, a stabilizing table 7 fixedly connected to the top of the column 5, there are two groups of stabilizing tables 7, two extrusion rollers 8 are rotatably connected between the two groups of stabilizing tables 7, and an adhesive is coated on the outside of the two extrusion rollers 8. By placing the tarpaulin on the outside of the pay-off reel 3 and pulling one end of the tarpaulin between the two extrusion rollers 8, the friction force generated between the tarpaulin and the extrusion rollers 8 during the winding process is used to make the two extrusion rollers 8 rotate in the same direction, thereby preventing the tarpaulin from being wrinkled, and at the same time removing the impurities adsorbed on the surface of the tarpaulin.

[0025] Furthermore, please refer to Figure 1 and Figure 2, in this embodiment, sliding grooves 9 are formed on the inner side walls of the two stabilizing platforms 7 close to each other. A slider 10 is slidably connected inside the sliding groove 9. A rotating shaft is rotatably connected inside the slider 10. The pressing roller 8 is rotatably connected to the slider 10 through the rotating shaft. When the thickness of the tarpaulin is different, the distance between the two pressing rollers 8 needs to be adjusted. By moving the slider 10 inside the sliding groove 9, and at the same time, the sliding groove 9 limits the slider 10, enabling the slider 10 to move linearly inside the sliding groove 9. By adjusting the position of the slider 10, the distance between the two pressing rollers 8 can be adjusted.

[0026] Further, please refer to Figure 1 and Figure 2 , in this embodiment, a disc 11 is rotatably connected inside the stabilizing platform 7. An arc groove 12 is formed inside the disc 11. There are two groups of arc grooves 12, and the two groups of arc grooves 12 are designed in a symmetrical structure. A through groove 13 is formed inside the sliding groove 9. One end of the slider 10 away from the rotating shaft is fixedly connected with a horizontal shaft 14. The horizontal shaft 14 extends into the arc groove 12 through the through groove 13. The connection mode between the horizontal shaft 14 and the arc groove 12 is a sliding connection. By rotating the disc 11, the arc groove 12 will rotate following the disc 11. At the same time, the arc groove 12 presses the horizontal shaft 14, enabling the horizontal shaft 14 to move to a position close to the arc groove 12. And the design of the through groove 13 greatly improves the smoothness when the horizontal shaft 14 moves. Then the sliders 10 approach each other inside the sliding groove 9, and the pressing rollers 8 approach each other.

[0027] Further, please refer to Figure 1 and Figure 3 , in this embodiment, a limiting rod 15 is rotatably connected inside the receiving frame 6. A first fixing sleeve 16 is fixedly connected to the right end of the outside of the limiting rod 15. A second fixing sleeve 17 is fixedly connected to the left end of the limiting rod 15. A threaded groove 18 is formed on the left end of the limiting rod 15 and on the left side of the second fixing sleeve 17. A sliding sleeve 19 is threadedly connected to the outside of the threaded groove 18. A third fixing sleeve 20 is rotatably connected to the outside of the sliding sleeve 19. Mounting seats 21 are fixedly connected to the outside of the first fixing sleeve 16, the second fixing sleeve 17, and the third fixing sleeve 20. By winding one end of the tarpaulin around the outside of the extension plate 23 and rotating the sliding sleeve 19, the sliding sleeve 19 reacts with the threaded groove 18 in a threaded manner. Then the sliding sleeve 19 slides on the outside of the threaded groove 18 and approaches the second fixing sleeve 17.

[0028] Further, please refer to Figure 1 and Figure 3, in this embodiment, a linkage rod 22 is rotatably connected inside the mounting base 21. One end of the linkage rod 22 away from the mounting base 21 is rotatably connected to the expansion plate 23. The expansion plate 23 is designed in an arc structure. By approaching the second fixing sleeve 17 from the third fixing sleeve 20, the linkage rod 22 rotates and unfolds, causing the expansion plate 23 to gradually move away from the limiting rod 15, thereby changing the diameter of the expansion plate 23. This enables the loose fabric to be quickly stretched by the expansion plates 23 on both sides during tarpaulin processing, improving the speed and quality of stretching the fabric.

[0029] In this embodiment, the implementation scenario is as follows: Place the tarpaulin outside the winding shaft 3, and pull one end of the tarpaulin between the two pressing rollers 8. Finally, wind it around the outside of the expansion plate 23. The limiting rod 15 rotates inside the receiving frame 6 to achieve automatic winding. By rotating the sliding sleeve 19, a threaded reaction occurs between the sliding sleeve 19 and the threaded groove 18. Then, the sliding sleeve 19 slides outside the threaded groove 18 and approaches the second fixing sleeve 17, causing the linkage rod 22 to rotate and unfold, making the expansion plate 23 gradually move away from the limiting rod 15, thereby changing the diameter of the expansion plate 23. This allows the loose fabric to be quickly stretched by the expansion plates 23 on both sides during tarpaulin processing, improving the speed and quality of stretching the fabric. Due to the conveying force generated by the tarpaulin and the frictional force generated by the pressing rollers 8, the two pressing rollers 8 rotate in the same direction, preventing wrinkles from appearing on the tarpaulin and simultaneously removing impurities adsorbed on the surface of the tarpaulin. When the thickness of the tarpaulin is different, the distance between the two pressing rollers 8 needs to be adjusted. By rotating the disc 11, the arc-shaped groove 12 rotates with the disc 11. At the same time, the arc-shaped groove 12 presses on the cross shaft 14, causing the cross shaft 14 to move to a position close to the arc-shaped groove 12. With the design of the through groove 13, the smoothness of the cross shaft 14 during movement is greatly improved, and then the sliders 10 approach each other inside the sliding grooves 9, causing the pressing rollers 8 to approach each other.

[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
