Description

TECHNICAL FIELD

[0001] The utility model relates to non - woven fabric processing technical field, concretely is the tension adjusting structure of non - woven fabric winding machine. BACKGROUND

[0002] Non - woven fabric is a new type of environmental protection material, and is interwoven by short fibers or filament fibers through physical, chemical or mechanical methods, has light, waterproof, breathable, tear -resistant and other excellent characteristics. It is widely used in medical, health, home, packaging and many other fields. In the production process of non - woven fabric, the winding machine is a very important equipment, which is responsible for winding the produced non - woven fabric into a roll according to certain tension and roll diameter. In order to ensure the quality and stability of non - woven fabric in the winding process, the tension adjusting structure in the winding machine is particularly important.

[0003] The patent with publication number CN216736730U discloses a winding equipment for non - woven fabric, comprising two first support frames, a tension roller is arranged between the two first support frames, a first fixing piece is arranged above each of the two first support frames, the two ends of the tension roller are rotatably connected with the two first fixing pieces, a rack frame is fixedly connected to the bottom end of the first fixing piece, a rack is arranged on one side of the rack frame, a first limiting block is arranged on one side of the rack frame, a second limiting block is arranged on the other side of the rack frame, a gear is meshingly connected on one side of the rack, a synchronous shaft is fixedly and penetratingly connected between the two gears, and a motor is fixedly installed on one of the first support frames. The utility model utilizes the setting mode of the rack frame, the gear, the servo motor and the synchronous shaft, so that the height of the tension roller can be freely adjusted, thereby the tension size during cloth winding can be adjusted at any time during the process of non - woven fabric winding, thereby the production efficiency and production quality of non - woven fabric winding are accelerated.

[0004] However, in actual application, the gear is driven by the servo motor to reverse, so as to adjust the up-down position of the rack frame and change the height of the tension roller. Although this adjustment mode realizes flexible tension control, frequent up-down adjustment of the height of the tension roller may adversely affect the tension roller itself. Frequent displacement will cause the tension roller to bear instantaneous impact force, thereby increasing the risk of wear and tear, and even possibly causing failure or malfunction of the equipment. This situation not only affects the reliability of the equipment, but also increases the cost of maintenance and replacement. In order to solve this problem, we propose a tension adjusting structure for non - woven fabric winding machine to realize more stable and durable tension adjusting function. UTILITY MODEL CONTENTS

[0029] Please refer to Figures 1-5 The present application provides a technical solution:

[0031] The tension detection piece 4 comprises two support columns 40 arranged in left and right symmetry, the bottom of the support column 40 is installed on the top of the base 3 through bolts, and the two support columns 40 are jointly connected with a tension roller 41, the tension roller 41 is used for directly contacting the non-woven fabric and detecting the tension change thereof;

[0032] The tension adjusting member 5 comprises an electric cylinder 50, which is used to drive the adjusting roller 53 to move up and down to change the tension. In the normal state, the movable rod of the electric cylinder 50 is in a semi-extended state, so as to facilitate the subsequent up and down movement to adjust the tension. The electric cylinder 50 is installed on the top of the base 3 through bolts. The movable rod of the electric cylinder 50 is fixedly connected with a support plate 51. The support plate 51 is used to bear the U-shaped frame 52 and the adjusting roller 53. The front and rear sides of the support plate 51 are both provided with the U-shaped frame 52. The U-shaped frame 52 is used to install the adjusting roller 53 and provide the rotating freedom. The two U-shaped frames 52 are both rotationally connected with the adjusting roller 53. The adjusting roller 53 is used to change the path length of the non-woven fabric to adjust the tension. The tension roller 41 and the two adjusting rollers 53 cooperate to make the non-woven fabric present an inverted triangular shape at the tension detecting member 4 and the tension adjusting member 5, so that the tension roller 41 can detect the tension of the non-woven fabric.

[0033] When the tension roller 41 detects that the tension decreases, the movable rod of the electric cylinder 50 is extended to drive the support plate 51 and the two U-shaped frames 52 to rise, so as to make the two adjusting rollers 53 move up to tighten the non-woven fabric. Conversely, the movable rod of the electric cylinder 50 is retracted to make the two adjusting rollers 53 move down to relax the non-woven fabric.

[0034] In the embodiment, as shown in the figure, Figure 1 One side of one of the support columns 40 is provided with a controller 6. The tension roller 41 and the electric cylinder 50 are respectively electrically connected with the controller 6 through wires.

[0040] The tension adjusting structure of the non-woven fabric winding machine of the embodiment is used in the following way: before the non-woven fabric enters the winding mechanism 2, it first passes through the tension detecting piece 4 on the top of the base 3, and the tension roller 41 fixed by the support column 40 directly contacts the non-woven fabric and detects the tension change in real time, and then the non-woven fabric is adjusted in path by the adjusting roller 53 of the tension adjusting piece 5; when the tension roller 41 detects that the tension is insufficient, the controller 6 controls the movable rod of the electric cylinder 50 to extend, drives the support plate 51 to vertically lift the two U-shaped frames 52, and makes the adjusting roller 53 tighten the path of the non-woven fabric; if the tension is too large, the movable rod of the electric cylinder 50 is retracted, drives the U-shaped frame 52 to descend along the positioning round rod 55, and the adjusting roller 53 is lowered to relax the non-woven fabric; during the winding process, the non-woven fabric forms an inverted triangular path between the tension roller 41 and the two adjusting rollers 53, the path length is dynamically adjusted to realize closed-loop control of the tension, and finally the winding is completed by the winding mechanism 2.

[0041] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application.
