Description

Technical Field

[0001] The utility model relates to the technical field of artificial fiber production, in particular to an automatic cutting device for artificial fibers used in bath towels. Background Art

[0002] When producing bath towels, a large amount of artificial fibers are needed. Before the artificial fibers are woven into bath towels, they are in a rolled-up state. When weaving, the rolled-up artificial fibers need to be cut. Therefore, an automatic artificial fiber cutting device is needed. However, the existing automatic artificial fiber cutting device still has certain defects during use.

[0003] For example, an automatic yarn cutting machine proposed in application number CN202323442496.1 includes a base, a fixed plate arranged on the upper surface of the base, a tensioning mechanism arranged on the fixed plate, an unwinding mechanism arranged on the input end of the tensioning mechanism, and a cutting mechanism arranged on the output end of the tensioning mechanism. The tensioning mechanism includes tensioning brackets arranged symmetrically on the left and right, and the two tensioning brackets are respectively provided with a first tensioning unit and a second tensioning unit. The first tensioning unit and the second tensioning unit have the same structure and both include a tensioning cylinder and a moving block. The tensioning cylinder is located at the top of the tensioning bracket The tensioning bracket is provided with an installation groove, the moving block is located in the installation groove, the cylinder shaft of the tensioning cylinder passes through the tensioning bracket and is fixedly connected to the moving block, the two moving blocks are connected by a tensioning roller, and a conveying roller is provided below the tensioning roller. In actual use, when the automatic yarn cutting machine is cutting the artificial fiber, although the tensioning roller can be used to tension the artificial fiber to ensure that the length of the cut artificial fiber is uniform, when the cutting mechanism descends to cut the artificial fiber, the artificial fiber is easily squeezed by the cutting knife to produce wrinkles, affecting the cutting effect.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-6 The utility model provides a technical solution: an automatic cutting device for artificial fibers for bath towels, comprising a support frame 1, a fixed plate 2 is fixedly installed on the top of the support frame 1, and rear connecting seats 3 are fixedly installed on both sides of the rear end of the fixed plate 2, a connecting rod 4 is rotatably installed inside the rear connecting seat 3, and a wire-releasing wheel 5 is sleeved at an equal angle on the outer ring of the connecting rod 4, and a front connecting seat 14 is fixedly installed on both sides of the front end of the fixed plate 2, and a wire feeding mechanism is installed on the inner side of the front connecting seat 14, and the wire feeding mechanism includes an upper rotating rod 15 rotatably installed on the top of the front connecting seat 14 and a lower rotating rod 16 at the bottom, and gears 17 are installed at both ends of the upper rotating rod 15 and the lower rotating rod 16, and upper transmission wheels 18 are installed on the outer ring of the upper rotating rod 15 at equal intervals, and lower transmission wheels 19 are installed on the outer ring of the lower rotating rod 16 at equal intervals, and the upper transmission wheels 18 correspond to the lower transmission wheels 19, and one end of the lower rotating rod 16 is connected to a servo motor 20, and the servo motor 20 is fixedly connected to the front connecting seat 14;

[0032] The design of the above structure enables that when the front end of the artificial fiber is connected to the upper transmission wheel 18 and the lower transmission wheel 19, starting the servo motor 20 can drive the lower rotating rod 16 to rotate at the bottom of the front connecting seat 14, and then the lower rotating rod 16 drives the upper rotating rod 15 to rotate at the top of the front connecting seat 14 by the engagement of the gear 17, and then in the process of the upper rotating rod 15 and the lower rotating rod 16 rotating, the upper transmission wheel 18 and the lower transmission wheel 19 can be driven to rotate respectively, so that the artificial fiber can be transported. At this time, the transportation of the artificial fiber will drive the pay-off wheel 5 and the connecting rod 4 to rotate inside the rear connecting seat 3, thereby improving the stability of the artificial fiber pay-off and transportation work.

An adjusting screw 10 is rotatably installed at the bottom of the positioning seat 9, and the adjusting screw 10 is connected through the fixed plate 2. The adjusting screw 10 is threadedly connected to the fixed plate 2, and a linkage wheel 11 is fixedly installed at the bottom of the adjusting screw 10.

[0036] The design of the above structure enables that when the artificial fiber is conveyed to the discharge plate 29, the starting cylinder 24 can drive the cutting knife 23 to descend, and when the cutting knife 23 descends, the limiting plate 22 can be used to limit the descending at the front end of the fixing seat 21. In the process of the cutting knife 23 descending, the pressure strip 26 will be driven to first squeeze and contact the artificial fiber, and then the cutting knife 23 continues to press down and will pass through the pressure strip 26 to cooperate with the base 28 to perform wrinkle-proof cutting on the artificial fiber. The setting of the spring 27 can push the pressure strip 26 to reset when the cylinder 24 drives the cutting knife 23 to rise and reset, so as to facilitate the cutting work again, and the sliding connection between the limiting rod 25 and the top of the cutting knife 23 can limit the extension and retraction of the pressure strip 26.
