Description

Technical Field

[0001] The present application relates to the technical field of rewinding machines, and in particular to a rewinding mechanism for an automatic rewinding machine. Background Art

[0002] The automatic rewinder is one of the important equipment on the modern production line and is widely used in papermaking, plastics, textiles, packaging and other industries. During the operation of the rewinder, from unwinding to cutting to rewinding, each step is crucial. During the unwinding process, the raw material roll is released smoothly through a specific unwinding device to ensure the stability of the material tension and provide a good foundation for the subsequent processing process. Next, the cutting device accurately cuts the raw material roll according to the preset width requirements to meet the needs of different products. Finally, the rewinding mechanism is responsible for winding the cut rolled material in an orderly manner to form a roll that meets the specifications.

[0003] However, in existing automatic rewinding machines, the design of the winding mechanism often has some technical problems. For example, the tension during the winding process is difficult to control, which can easily lead to uneven tightness of the roll. Excessive tension may cause the coil to stretch during the winding process, resulting in an uneven surface and even wrinkles or creases. Excessive tension may cause the coil to relax during winding, forming an irregular appearance, thereby affecting the quality and appearance of the product. Therefore, there is room for improvement. Utility Model Content

[0004] In order to solve the problem that the tension is difficult to control during the rewinding process of the rewinder, the present application provides a rewinding mechanism for an automatic rewinder.

[0007] Since the tension in the winding process is difficult to control, it is easy to cause the tightness of the roll to be inconsistent. Excessive tension may cause the coil to stretch during the winding process, resulting in an uneven surface, or even wrinkles or creases.

When the tension is too large, the control cylinder can push the winding frame to tilt upward to reduce the winding. The contact pressure between the rod and the coil reduces the tension. When the tension is too small, the control cylinder can pull the winding frame to tilt downward, increase the contact pressure between the winding rod and the coil, increase the tension, and achieve precise control of the tension by accurately controlling the stroke and speed of the cylinder; by controlling the settings of the cylinder, the winding frame and the winding rod, it is helpful to achieve precise control of the coil tension, which can be adjusted in real time and within a wide range, and can meet the different tension requirements of coils of different materials and thicknesses, with strong applicability, thereby ensuring the winding quality and appearance of the coil.

The centers of the two transmission rollers 51 are located on the same axis, and the two transmission rollers 51 are installed on the same plane. In this embodiment, the sizes of the two transmission rollers 51 are consistent.

[0033] Reference Figure 1 The driving assembly 52 includes a driving wheel 521, two driven wheels 522, a synchronous belt 523 and a servo motor 524.

The two driven wheels 522 are respectively sleeved and fixed on the ends of the two transmission rollers 51, and the two driven wheels 522 are located on the same side of the two transmission rollers 51. The synchronous belt 523 is tensioned on the driving wheel 521 and the two driven wheels 522 in sequence, so that the two transmission rollers 51 rotate at the same speed and direction, ensuring the stability and continuity of the coil during the transmission process and improving the production efficiency.

It can guide the coil from the transmission roller 51 to the correct path on the winding frame 2, ensuring that the coil can be smoothly and accurately transferred to the winding frame 2, avoiding deviation or distortion during the transmission process.

[0035] Reference Figure 2A hinge assembly 7 is installed on the frame 1, and the hinge assembly 7 includes two hinge plates 71 and a plurality of fixing bolts 72. The two hinge plates 71 are symmetrically installed on both sides of the winding frame 2, and the two ends of the winding frame 2 are respectively hingedly installed on the two hinge plates 71.

[0036] Reference Figure 2 The control assembly 4 includes a first articulated seat 41, a second articulated seat 42 and a control cylinder 43. In this embodiment, the first articulated seat 41 and the second articulated seat 42 have the same structure.

The cylinder end of the control cylinder 43 is hingedly installed on the first articulated seat 41, and the output end of the control cylinder 43 is hingedly installed on the second articulated seat 42; when the tension is too large, the control cylinder 43 can push the winding frame 2 to tilt upward, reduce the contact pressure between the winding rod 3 and the coil, and reduce the tension. When the tension is too small, the control cylinder 43 can pull the winding frame 2 to tilt downward, increase the contact pressure between the winding rod 3 and the coil, and increase the tension. By accurately controlling the stroke and speed of the cylinder 43, accurate control of the tension is achieved.

[0037] Reference Figure 3 A material blocking assembly 8 is installed on the winding rod 3, and the material blocking assembly 8 includes two material blocking plates 81. The two material blocking plates 81 are relatively installed on the winding rod 3, and the winding rod 3 passes through the center of the material blocking plate 81 and is fixed to the material blocking plate 81. In this embodiment, the winding rod 3 can be detachable from the winding frame 2, and the material blocking plate 81 and the winding rod 3 can also be detachable.

[0038] Reference Figure 3 , a blocking wheel 9 and a blocking screw 10 are installed on any blocking plate 81, and there are two groups of blocking wheels 9 and blocking screws 10 on each blocking plate 81, and the two groups of blocking wheels 9 and blocking screws 10 are symmetrically installed on both sides of the length direction of the blocking plate 81, each blocking screw 10 penetrates the blocking plate 81 and is threadedly connected to the blocking plate 81, and the blocking wheel 9 is installed on the end of the blocking screw 10. In this embodiment, the blocking wheel 9 is installed on the corresponding blocking plate 81 close to the adjacent blocking plate 81, which helps to prevent the coil from being offset or twisted due to uneven force during the winding process, and can more accurately control the winding position and winding diameter of the coil, thereby improving the winding accuracy and quality.

[0039] The implementation principle of the winding mechanism for an automatic rewinding machine in the embodiment of the present application is as follows: after the coil is unwound and cut, the servo motor 524 starts working, the driving wheel 521 rotates through the synchronous belt 523 to drive the two driven wheels 522 to rotate simultaneously, and the two transmission rollers 51 move in the same direction to transmit the coil. After the coil is guided by the guide roller 6, it is wound on the winding rod 3. At the same time, the on-site personnel adjust the contact pressure between the winding rod 3 and the coil according to the actual situation, thereby changing the tension of the coil. When the tension is too large, the control cylinder 43 can push the winding frame 2 to tilt upward, reduce the contact pressure between the winding rod 3 and the coil, and reduce the tension. When the tension is too large, the control cylinder 43 can push the winding frame 2 to tilt upward, reduce the contact pressure between the winding rod 3 and the coil, and reduce the tension. When the tension is too small, the control cylinder 43 can pull the winding frame 2 to tilt downward, increase the contact pressure between the winding rod 3 and the coil, and increase the tension. By accurately controlling the stroke and speed of the cylinder 43, accurate control of the tension is achieved. By controlling the settings of the cylinder 43, the winding frame 2 and the winding rod 3, etc., it is helpful to achieve accurate control of the tension of the coil, which can be adjusted in real time and within a wide range of adjustment. It can meet the different tension requirements of coils of different materials and thicknesses, and has strong applicability, thereby ensuring the winding quality and appearance of the coil. At the same time, the operation is simple and intuitive, does not require complicated equipment or technology, reduces the difficulty of operation, and improves work efficiency.
