Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a cloth stretching machine with a curling removal device. Background Art

[0002] The cloth pulling machine with hem removal device is a key equipment to improve textile processing efficiency, ensure product quality and optimize production process. It is especially indispensable in large-scale and high-efficiency clothing production.

[0003] In the prior art, such as the Chinese patent number: CN213923475U, "A cloth pulling machine with a curling device", comprises a workbench and a cloth pulling machine, a chassis is fixedly installed on the top of the cloth pulling machine, a cloth roll is rotatably installed on the top of the chassis, two brackets are fixedly installed on the outer surface of one side of the chassis, a fixed block is fixedly installed between the two brackets, a baffle is fixedly installed on one side of the top of the cloth pulling machine, a telescopic rod is fixedly installed on the bottom outer surface of the baffle, a roller is rotatably installed on one end of the telescopic rod, a spring is sleeved on the outer surface of the telescopic rod, cloth is laid on the top of the workbench, and bases are fixedly installed at both ends of the bottom of the workbench. In the utility model, through the support rods, spring rods and rollers, when the cloth pulling machine lays the cloth, the rollers can replace manual labor to press the cloth, thereby reducing the fatigue of the staff, and it is more convenient for the staff to use and increase the practicality of the cloth pulling machine.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that in the initial use, the horizontal height of the pressure roller needs to be adjusted. If the horizontal height of the pressure roller is inappropriate, the cloth tension is unevenly distributed, some parts are too tight and some parts are loose, resulting in uneven cloth surface, seriously affecting product quality. At the same time, during operation, the diameter of the cloth roll is gradually reduced. The change in the diameter of the cloth roll directly affects the linear speed of the cloth roll on the reel. When the roll diameter is reduced, that is, the cloth roll becomes smaller, at the same rotation speed, the circumference of the cloth roll is reduced, and the contact area is reduced, resulting in an increase in the tension of the cloth on the shaft. The tension change may cause the cloth to be too tight, broken, or torn, increase the waste generation rate, and increase production costs. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0022] See also Figure 1-4The utility model provides a technical solution: a cloth pulling machine with a curling device, comprising: a working frame 1, two limit plates 2 are fixedly connected to the bottom of the working frame 1, a plurality of tooth grooves 3 are provided on the outer surfaces of the two limit plates 2, sliding holes 4 are provided on the outer surfaces of the two limit plates 2, a fixing rod 5 is movably embedded on the inner surfaces of the two sliding holes 4, a tensioning wheel 6 is movably sleeved on the outer surface of the fixing rod 5, two fixing blocks 7 are fixedly connected to the outer surface of the fixing rod 5, a rotating shaft 8 is movably embedded on the outer surfaces of the two fixing blocks 7, and one of the rotating shafts 8 A handle 9 is fixedly installed on the outer surface of the two rotating shafts 8, synchronous wheels 10 are fixedly installed on the outer surfaces of the two synchronous wheels 10, and a synchronous belt 11 is transmission-connected to the outer surfaces of the two synchronous wheels 10. A notch 12 is provided on the outer surface of one of the fixed blocks 7, a spring 13 is fixedly connected to the inner surface of the notch 12, a slider 14 is fixedly connected to the outer surface of the spring 13, a clamping block 15 is fixedly connected to the outer surface of the slider 14, and a handle 2 16 is fixedly connected to the outer surface of the clamping block 15, so that the tension of the cloth is evenly distributed, the cloth surface is flat, and the product quality is guaranteed.

[0023] like Figure 1-4 As shown, threaded rods 19 are movably embedded in the inner surfaces of the two fixed blocks 7, and movable blocks 20 are threadedly connected to the outer surfaces of the two threaded rods 19, and springs 21 are fixedly connected to the bottoms of the two movable blocks 20, and pulleys 22 are fixedly installed on the outer surfaces of the two threaded rods 19, and transmission belts 23 are transmission-connected to the outer surfaces of the two pulleys 22, and a handle 3 24 is fixedly connected to the top of one of the threaded rods 19, so as to avoid the problem of excessive tension on the coiled material due to the reduction of the coiled material diameter, resulting in the fabric being too tight and broken or torn, thereby reducing the waste generation rate and reducing the production cost.

[0024] like Figure 1-4 As shown, the outer surfaces of the two fixed blocks 7 are fixedly connected to the limiting rods 17, and the two limiting plates 2 are provided with limiting grooves 18 on one side close to the two limiting rods 17. The two limiting rods 17 are movably embedded in the inner surfaces of the two limiting grooves 18. The outer surfaces of the two movable blocks 20 are fixedly connected to the positioning rods 25, and the two positioning rods 25 are movably embedded in the inner surfaces of the two limiting grooves 18. The limiting grooves 18 can limit the movement trajectory of the limiting rods 17 to avoid derailment of the limiting rods 17 and affect the use of the equipment.

[0025] like Figure 1-4 As shown, the two threaded rods 19 are movably embedded in the inner surface of the work frame 1, the two springs 21 are fixedly connected to the tops of the two fixed blocks 7, and the two springs 21 are movably sleeved on the outer surfaces of the two threaded rods 19. The horizontal height of the springs 21 is adjusted, and then the elastic force parameters of the springs 21 are adjusted to reduce the elastic force of the springs 21, thereby avoiding the breakage of the coil due to excessive tension.

[0026] Working principle: This equipment is a cloth pulling machine without curling device. Before use, the cloth is passed through each guide roller and tension wheel 6 in sequence as required, and then the handle 2 16 is manually pulled, and the handle 2 16 drives the block 15 to move, so that the block 15 no longer limits the synchronous wheel 10, and the block 15 drives the slider 14 to move on the inner surface of the slot 12, and squeezes the spring 13, so that the spring 13 obtains elastic potential energy. At this time, the block 15 no longer limits one of the synchronous wheels 10, and then the handle 1 9 is manually rotated, and the handle 1 9 drives one of the rotating shafts 8 to rotate, wherein A rotating shaft 8 drives one of the synchronous wheels 10 to rotate, and one of the synchronous wheels 10 drives the other synchronous wheel 10 to rotate through a synchronous belt 11. Because the two synchronous wheels 10 are engaged with the tooth grooves 3 on the two limit plates 2, when the two synchronous wheels 10 rotate at the same time, they will drive the two fixed blocks 7 to move up and down. The two fixed blocks 7 drive the tensioning wheel 6 to move up and down through the fixed rod 5, and there is a certain gap between the slider 14 and the notch 12, so the fixed block 7 can shake up and down when working, and the cooperation of the limit rod 17 and the limit groove 18 can The moving track of the fixed block 7 is limited. When the coil is in a taut state, the handle 2 16 is released, and the spring 13 releases the elastic potential energy, so that the clamping block 15 is re-stuck on one of the synchronous wheels 10, limiting the rotation of one of the synchronous wheels 10, forming a self-locking, and thus preventing the tension wheel 6 from continuing to move downward. When the equipment is running, when the diameter of the coil changes, the tension changes too much, the handle 3 24 is manually rotated, and the handle 3 24 drives one of the threaded rods 19 to rotate, and one of the threaded rods 19 is connected to the pulley 22 and the transmission belt 2 3, so that the other threaded rod 19 rotates synchronously. When the two threaded rods 19 rotate, they drive the two moving blocks 20 to move up and down. Because the contact surface of the moving block 20 and the spring 21 is provided with a thick rubber gasket, the normal operation of the spring 21 will not be affected even if the moving plate 21 and the fixed block 7 are fixed in position. Therefore, when the moving block 21 moves up and down, the elastic force parameters of the two springs 21 change, and then the elastic force of the two springs 21 changes. The positioning rod 25 can prevent the moving block 20 from rotating when the threaded rod 19 rotates.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
