Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric winding technology, specifically to a winding mechanism for a nonwoven fabric printing machine. Background Technology

[0002] Nonwoven fabric winding mechanisms are widely used in various nonwoven fabric production lines. Their basic structure typically includes key components such as a frame, winding rollers, a drive system, a tension control system, and a guiding system. These mechanisms use a drive system to rotate the winding rollers and a tension control system to adjust the tension of the nonwoven fabric during the winding process, ensuring winding quality.

[0003] However, the guiding systems (such as guide rollers and side guide plates) of some winding mechanisms are not designed with high precision, making it difficult to effectively correct the slight deviations of the nonwoven fabric during the winding process. During the winding process, the edges of the nonwoven fabric gradually deviate from the center line of the winding roller, resulting in uneven edges of the wound roll, or even spiral deviations. As the number of winding layers increases, relative misalignment may occur between the layers of nonwoven fabric, affecting the overall tightness and stability of the roll. Winding deviation is often accompanied by uneven tension distribution, further aggravating the deformation and wrinkles of the nonwoven fabric, reducing product quality. Moreover, most existing winding mechanisms lack the function of real-time monitoring of the nonwoven fabric winding status, making it difficult to detect and correct deviation problems in a timely manner. Winding deviation problems not only directly affect the appearance quality and physical properties of the nonwoven fabric roll, but may also cause difficulties in subsequent cutting, packaging and other processes, increasing production costs and scrap rates. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing winding mechanisms are unable to effectively correct the slight deviations of nonwoven fabric during the winding process, resulting in uneven edges on the wound roll, affecting the appearance quality and physical properties of the nonwoven fabric roll, and potentially causing difficulties in subsequent cutting, packaging, and other processes, increasing production costs and scrap rates.

[0005] To solve the above problems, the technical solution adopted by this utility model is a winding mechanism for a non-woven fabric printing machine, including a frame structure. One end of the frame structure is provided with an adjusting roller structure and a winding roller structure. Above the frame structure, at both ends of the winding roller structure, are power roller mechanisms. The adjusting roller structure includes a roller body. Support base one and support base two are respectively fixed at both ends of the roller body on the upper side of the frame structure. One side of the support base has a through hole, and a support tube is fixed to one side of the support base at the through hole. One end of the roller body is located at the support tube. The machine has a first connecting groove, a motor is fixed on the upper side of the frame structure, a lead screw is fixed through the through hole at the output end of the motor, a threaded hole is opened on one side of the roller body to be threadedly connected to the lead screw, a connecting shaft is fixed on one side of the second support base, and a second connecting groove is opened on the other end of the roller body; a support frame is fixed on one end of the upper side of the frame structure at the winding roller structure, a limit frame is fixed on one end of the support frame, a connecting tube is provided for limiting sliding inside the limit frame, a positioning roller is rotatably provided inside the connecting tube, a connecting plate is fixed on one side of the limit frame, and an infrared distance sensor is fixed on one side of the connecting plate.

[0006] As a further embodiment of this utility model, sliding bearings are provided between the first connecting groove and the support tube, and between the second connecting groove and the connecting shaft, which makes the rotation and translation of the roller body smoother and more fluid.

[0007] As a further embodiment of this utility model, several anti-slip grooves are provided on the outer side of the roller body, which facilitates the translation of the non-woven fabric.

[0008] As a further embodiment of this utility model: a nonwoven fabric is wound on the outer side of the winding roller structure, the lower side of the positioning roller is in contact with the upper side of the nonwoven fabric on the outer side of the winding roller structure, and the infrared distance sensor is aligned with the edge of the nonwoven fabric. The infrared distance sensor can monitor the distance between the edge of the nonwoven fabric and the sensor in real time, so as to adjust the winding position of the nonwoven fabric in a timely manner by adjusting the roller structure.

[0009] As a further embodiment of this invention: both the motor and the infrared distance sensor are electrically connected to an external power source.

[0010] Compared with the prior art, the advantages of this utility model are as follows: This application adds an infrared distance sensor and an adjusting roller structure. The infrared distance sensor is aligned with the edge of the nonwoven fabric, which can monitor the distance between the nonwoven fabric and the infrared distance sensor at all times, so as to determine whether the nonwoven fabric has shifted. If the nonwoven fabric is detected to have shifted, the motor can be started to drive the lead screw to rotate, so as to adjust the position of the roller body, thereby adjusting the winding position of the nonwoven fabric to correct the shift.

[0018] 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.

[0019] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0020] Combined with appendix Figure 1-3It can be seen that the frame structure includes a frame structure 1. One end of the frame structure 1 is equipped with an adjusting roller structure and a winding roller structure 2. The upper part of the frame structure 1 is equipped with a power roller mechanism 3 at both ends of the winding roller structure 2, which can easily drive the winding roller structure 2 to rotate and wind. This is the existing structure. The adjusting roller structure includes a roller body 4. Several anti-slip grooves are opened on the outer side of the roller body 4, which can easily drive the nonwoven fabric 15 to move horizontally. Support base 1 5 and support base 2 6 are fixed on the upper side of the frame structure 1 at both ends of the roller body 4, respectively. The side of support base 1 5 is provided with a through hole 5.1. A support tube 5 is fixed on one side of support base 1 5 at the through hole 5.1. 2. One end of the roller body 4 is provided with a connecting groove 4.1 at the support tube 5.2. A motor 7 is fixed on the upper side of the frame structure 1. The output end of the motor 7 passes through the through hole 5.1 and is fixed with a lead screw 8. A threaded hole 4.2 is provided on one side of the roller body 4, which is threaded to the lead screw 8. The rotation of the lead screw 8 can control the translation of the roller body 4. A connecting shaft 6.1 is fixed on one side of the support seat 6. A connecting groove 4.3 is provided at the other end of the roller body 4. Sliding bearings are provided between the connecting groove 4.1 and the support tube 5.2, and between the connecting groove 4.3 and the connecting shaft 6.1, so that the rotation and translation of the roller body 4 can be smoother.

[0021] Combined with appendix Figure 1 , 4 It can be seen that a support frame 9 is fixed on one end of the take-up roller structure 2 on the upper side of the frame structure 1. A limit frame 10 is fixed on one end of the support frame 9. A connecting tube 11 is provided on the inner side of the limit frame 10 for limiting and sliding. It can move as the radius of the nonwoven fabric 15 increases during take-up. A positioning roller 12 is rotatably provided on the inner side of the connecting tube 11. A connecting plate 13 is fixed on one side of the limit frame 10. An infrared distance sensor 14 is fixed on one side of the connecting plate 13. It can move synchronously with the displacement of the connecting tube 11 and always illuminate the edge of the nonwoven fabric 15. The nonwoven fabric 15 is rolled on the outer side of the take-up roller structure 2. The lower side of the positioning roller 12 is in contact with the upper side of the nonwoven fabric 15 on the outer side of the take-up roller structure 2. The infrared distance sensor 14 is aligned with the edge of the nonwoven fabric 15. The infrared distance sensor 14 can monitor the distance between the edge of the nonwoven fabric 15 and the infrared distance sensor in real time, so as to adjust the take-up position of the nonwoven fabric 15 in a timely manner by adjusting the roller structure. The motor 7 and the infrared distance sensor 14 are both electrically connected to an external power supply.

[0022] The working principle of this application is as follows: When the nonwoven fabric 15 is being wound up, the nonwoven fabric 15 first wraps around the roller body 4 and is rolled onto the outside of the winding roller structure 2. At the same time, the lower side of the positioning roller 12 contacts the upper side of the nonwoven fabric 15 on the outside of the winding roller structure 2. When the roller body 4 rotates, the motor 7 is not powered on, and the shaft of the motor 7, which is fixed to the lead screw 8, is not affected by electromagnetic force, so it does not affect the rotation of the roller body 4. The infrared distance sensor 14 moves synchronously with the displacement of the connecting pipe 11. If the infrared distance sensor 14 detects a change in the position of the edge of the nonwoven fabric 15, the motor 7 can be started by an external computer to drive the lead screw 8 to rotate, so as to adjust the position of the roller body 4. When the motor 7 is running, the lead screw 8 will drive the roller body 4 to move. The roller body 4 will not rotate, but will directly adjust the position of the nonwoven fabric through the friction between its surface and the nonwoven fabric 15. After adjustment, the motor 7 is powered off, and the roller body 4 can rotate with the winding of the nonwoven fabric 15.

[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
