The following embodiments are used to illustrate the present utility model but not to limit the scope of the present utility model.

[0031] As Figures 2 - 7 shown, the present utility model provides a rewinding non-stop line speed material receiving mechanism, which is mainly used in combination with the double-station rewinding mechanism 900 in the coating equipment, enabling the coating equipment to automatically receive materials without reducing the speed, and ensuring the consistency of the line speed during the roll change process of the double-station rewinding mechanism 900. Figure 1 It is a schematic diagram of the combined use of the present utility model and the double-station rewinding mechanism 900, where the double-station rewinding mechanism 900 is prior art and will not be described in detail here.

[0032] The present utility model includes a tension swing mechanism 100 provided on the frame 401, a material receiving pressure roller mechanism 200 provided on the base 400, and two cutting mechanisms 300. Among them, the tension swing mechanism 100, the material receiving pressure roller mechanism 200, and the cutting mechanism 300 are arranged in sequence from left to right, and the material receiving pressure roller mechanism 200 and the cutting mechanism 300 are arranged close to the double-station rewinding mechanism 900.

[0033] The tension swing mechanism 100 includes a swing roller 101, a swing assembly for driving the swing of the swing roller 101, and several guide rollers 102. The swing assembly includes a connecting rod 601, two swing driving cylinders 602, two second swing arms 603, and two connecting plates 604.

[0034] The connecting rod 601 is arranged on the frame 401 along its length direction. Both ends of the connecting rod 601 pass through the frame 401, and both ends are located outside the frame 401. One end of each of the two second swing arms 603 is connected to each end of the connecting rod 601 located outside the frame 401, and the other end of the second swing arm 603 is connected to the driving end of a swing driving cylinder 602. The fixed end of each swing driving cylinder 602 is connected to the outer side wall of the frame 401. One end of each of the two connecting plates 604 is respectively placed at both ends of the connecting rod 601 located inside the frame 401, and both ends of the swing roller 101 along its length direction are respectively connected to the other end of the corresponding connecting plate 604. The guiding rollers 102 are arranged on the frame 401 and are respectively arranged on both sides of the swing roller 101 in an up-and-down staggered manner.

[0035] The guiding rollers 102 mainly play a role in guiding the material 000, and there are no special restrictions on their quantity and arrangement. In the present utility model, a total of five guiding rollers 102 are provided. Among them, a guiding roller 102 is arranged below the left side of the guiding rollers 102, and the material 000 enters through this guiding roller 102. Four guiding rollers 102 are arranged on the right side of the swing roller 101, and the four guiding rollers 102 are arranged in an up-and-down and left-and-right staggered manner, and the position of the guiding roller 102 far from the swing roller 101 is lower than the position of the swing roller 101, and the two form a wrap angle. After the material 000 enters from the leftmost guiding roller 102, it respectively bypasses the other guiding rollers 102 and the swing roller 101 in sequence, and then is led out by the rightmost guiding roller 102 to the following material receiving and pressing roller mechanism 200. It is defined that the material 000 enters from the left and exits from the right, that is, in the X-axis direction.

[0036] When the tension of the material 000 located between the swing roller 101 and the guiding rollers 102 changes due to the operation of this mechanism, the swing driving cylinder 602 drives the connecting rod 601 to rotate or swing accordingly, and then synchronously drives the swing roller 101 to swing according to the tension change, so as to offset the tension change on the material 000 and stabilize the stable operation of this mechanism.

[0037] Preferably, the swing driving cylinder 602 is a low-friction cylinder. The cylinder can still move when the pressure difference between the two sides is very small. At this time, the thrust or pull force generated by the cylinder piston rod is very small, so that the material 000 will not be broken during the winding process.

[0038] The material receiving and pressing roller mechanism 200 is arranged on the base 400, and it includes a transition roller 201, a pressing roller 202, a first driving mechanism and two cutting mechanisms 300. Among them, the first driving mechanism includes two first driving cylinders 501 and two first swing arms 502. The first driving mechanism drives the pressing roller 202 to move along the X-axis direction, that is, to move towards or away from the double-station winding mechanism 900. The cutting mechanism 300 is used to cut the material 000 located between the pressing roller 202 and the double-station winding mechanism 900.

[0039] Preferably, the material receiving pressure roller mechanism 200 is arranged on a moving seat, and the moving seat is slidably connected to the base 400 through a linear movement module, so as to adjust the distance between it and the tension swing mechanism 100 and the double-station winding mechanism 900 according to actual use needs.

[0040] Specifically, the moving seat includes two moving vertical plates 701 and several support columns 702 connected between the two moving vertical plates 701. On one side of the bottom surface of each moving vertical plate 701, there is a gear guide rail 703. The linear movement module sliding includes a third driving motor 704, a synchronous transmission rod 705, and two linear guide rails 706. Gears 7051 meshing with the gear guide rails 703 are arranged at both ends of the synchronous transmission rod 705.

[0041] The two linear guide rails 706 are arranged in parallel along the X-axis direction on the top surface of the base 400. The two ends of the synchronous transmission rod 705 pass through the base 400, and the gears 7051 at both ends of the synchronous transmission rod 705 are respectively located on the outer side surfaces of the base 400. Each moving vertical plate 701 is slidably connected to its corresponding linear guide rail 706 through a slider, and the gear guide rail 703 on each moving vertical plate 701 meshes with the gear 7051 on its corresponding side; the fixed end of the third driving motor 704 is arranged on the outer side wall of a moving vertical plate 701, and its driving end is connected to the gear 7051 on this moving vertical plate 701. When the third driving motor 704 is started, the moving seat moves along the linear guide rail 706.

[0042] Preferably, two travel switches 707 are arranged at intervals in sequence on any one of the linear guide rails 706, and a touch block is arranged on the inner side wall of the bottom surface of the moving vertical plate 701 corresponding to this linear guide rail 706. When the touch block moves to any one of the travel switches 707 along with the moving vertical plate 701, the moving seat stops at this position.

[0043] One end of each of the above-mentioned first swing arms 502 is rotatably connected to the inner side surface of a moving vertical plate 701 respectively. The two ends of the pressure roller 202 along its length direction are respectively connected to the free ends of the above two first swing arms 502. The fixed ends of the two first driving cylinders 501 are respectively connected to the inner side surfaces of their corresponding moving vertical plates 701, and the driving ends of the two first driving cylinders 501 are respectively connected to the free ends of the two first swing arms 502. The two first driving cylinders 501 jointly drive the two first swing arms 502 and the pressure roller 202 to move towards or away from the double-station winding mechanism 900. The transition roller 201 is arranged between the two moving vertical plates 701 along its length direction, and the transition roller 201 is located at the upper left position of the pressure roller 202, and a wrap angle is formed between the two, which is convenient for transporting the material 000. The material 000 led out by the tension swing mechanism 100 passes through the transition roller 201 and the pressure roller 202 in sequence, and then is connected to the double-station winding mechanism 900 through the pressure roller 202.

[0044] Preferably, horizontal adjusting members 2012 are provided at both ends of the transition roller 201. When observing that the material 000 is uneven on the surface of the transition roller 201, the position of the transition roller 201 can be adjusted by adjusting the horizontal adjusting members 2012.

[0045] Two material cutting mechanisms 300 are provided on the moving seat, and are symmetrically arranged on the upper and lower sides of the pressure roller 202 in a mirror image, and the two material cutting mechanisms 300 are located on the side of the pressure roller 202 away from the transition roller 201. Each material cutting mechanism 300 includes a cutter holder 301, a cutter 302 and two second driving cylinders 303.

[0046] Taking the material cutting mechanism 300 located above the pressure roller 202 as an example for illustration. The fixed ends of the two second driving cylinders 303 are respectively provided on the two moving vertical plates 701, the driving ends of the two second driving cylinders 303 are jointly connected to the cutter holder 301, the cutter 302 is arranged on the cutter holder 301 along its length direction, and the direction of the cutter 302 is obliquely downward and faces the material 000 located between the pressure roller 202 and the double-station winding mechanism 900. Starting the above two second driving cylinders 303, the cutter 302 can quickly move towards the material 000 and cut off the material 000 located between the pressure roller 202 and the double-station winding mechanism 900. The material cutting mechanism 300 of the present utility model can instantaneously pierce the material at a coating equipment line speed of 500 m / min.

[0047] The material cutting mechanism 300 located below the pressure roller 202 is the same as above, but the direction of the cutter 302 thereon is obliquely upward. The two material cutting mechanisms 300 are used in cooperation with the first winding roller 901 and the second winding roller 902 in the double-station winding mechanism 900.

[0048] Preferably, a brush 304 is further provided on each cutter holder 301. Each brush 304 is arranged on the side of the cutter close to the pressure roller 202, and each brush is arranged at an angle with the cutter 302. When the cutter 302 on the material cutting mechanism 300 instantaneously cuts off the material 000 located between the pressure roller 202 and the double-station winding mechanism 900, the brush 304 on the material cutting mechanism 300 can simultaneously perform the function of smoothing the material, so that the wound material 000 is flat and does not wrinkle.

[0049] The operation process of the present utility model is as follows:

[0050] The pressure roller 202 is driven by the first driving mechanism to abut against the first winding roller 901 on the double-station winding mechanism 900. The material 000 is led out by the tension swing mechanism 100, reaches the pressure roller 202 through the transition roller 201, and the first winding roller 901 winds the material 000 therefrom. Before the first winding roller 901 is about to finish winding, the second winding roller 902 rotates in advance to the waiting position. When the first winding roller 901 finishes winding, the cutter 302 on the material cutting mechanism 300 cuts off the material 000, and the brush 304 simultaneously levels the material 000 on the first winding roller 901. During this period, the pressure roller 202 adjusts its position through the first driving mechanism according to the diameter of the winding material on the first winding roller 901; after the first winding roller 901 finishes winding, the second winding roller 902 rotates to the position where it abuts against the pressure roller 202, and the second winding process is started. The first winding roller 901 starts the roll-changing operation. When the second winding roller 902 finishes, the cutter 302 on the other material cutting mechanism 300 cuts off the material 000, and the brush 304 simultaneously levels the material 000 on the second winding roller 902; circulating in this way, automatic material feeding and roll-changing without speed reduction are realized, and during the above cutting process or roll-changing process, through the cooperation of the tension swing mechanism 100, the generated tiny tension changes are well compensated, making the operation of this mechanism more stable.

[0051] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
