[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] like Figure 1 As shown, a plastic grille winding device with automatic feeding and cutting includes a frame 1, a feeding assembly and a winding assembly; the frame 1 is welded by profiles, the front end of the frame 1 is the feeding assembly, and the rear end of the frame 1 is the winding assembly.

[0045] The feeding assembly comprises:

[0046] The first feeding roller group 2, such as Figure 5As shown, the first feeding assembly includes a first fixed roller 201 and a first pressure roller 202, both of which are rotatably mounted on the side plate 101 of the frame 1, wherein adjustment mechanisms are provided at both ends of the first pressure roller 202, and the adjustment mechanisms can adjust the spacing between the first pressure roller 202 and the first fixed roller 201 to adapt to plastic grilles of different thicknesses. The first fixed roller 201 can be driven to rotate by a first rotary drive mechanism 203, and the first rotary drive mechanism 203 adopts a servo motor with a reducer, and controls the number of rotations through a servo encoder, thereby realizing fixed-length supply of the plastic grille. After the plastic grille comes out of the front-end production equipment, it passes between the first fixed roller 201 and the first pressure roller 202, and the first feeding roller group 2 is used to pull the plastic grille out of the front-end production equipment.

[0047] The second feeding roller group 3, such as Figure 5 As shown, the second feeding roller group 3 includes a second fixed roller 301 and a second pressure roller 302, both of which are rotatably mounted on the side plate 101 of the frame 1. Like the first feeding roller group 2, adjustment mechanisms are provided at both ends of the second pressure roller 302. The adjustment mechanisms can adjust the spacing between the second pressure roller 302 and the second fixed roller 301 to adapt to plastic grilles of different thicknesses. The second fixed roller 301 can be driven to rotate by a second rotary drive mechanism 303. The second rotary drive mechanism 303 adopts a servo motor with a reducer, and the number of rotations is controlled by a servo encoder, thereby realizing fixed-length supply of the plastic grille. The plastic grille passes between the second fixed roller 301 and the second pressure roller 302, and is used to feed the plastic grille into the rear winding assembly.

[0048] Fixing component 4, such as Figure 3 , 4, 6, and 7, it is located between the first feed roller group 2 and the second feed roller group 3, and is mainly used for front and rear fixing of the plastic grille to facilitate cutting. The fixing assembly 4 includes a fixed beam 401, a first lifting beam 402, and a second lifting beam 403. The fixed beam 401 and the first lifting beam 402 are used to support the plastic grille. The fixed beam 401 is fixedly mounted on the side plate 101 of the frame 1. A gap is provided between the fixed beam 401 and the first lifting beam 402 in the horizontal direction. Supports 102 are installed on the inner sides of the two side plates 101. The first lifting drive mechanism 404 is provided with two groups, which are respectively installed on two supports 102. The bottom surfaces of both ends of the first lifting beam 402 are connected to the movable ends of the first lifting drive mechanism 404. The first lifting beam 402 is driven by the first lifting drive mechanism 404 to achieve lifting movement. In this solution, the first lifting drive mechanism 404 adopts an oil cylinder. When the first lifting beam 402 is in a low position, the tops of the first lifting beam 402 and the fixed beam 401 are at the same height. When the first lifting beam 402 is in a high position, the top surface height of the first lifting beam 402 is higher than the top surface height of the fixed beam 401. The cross-section of the second lifting beam 403 is an inverted U-shape. The U-shaped opening of the second lifting beam 403 is opposite to the horizontal gap between the fixed beam 401 and the first lifting beam 402. The second lifting beam 403 is driven to rise and fall by the second lifting drive mechanism 405. When the second lifting beam 403 descends, it can press the plastic grille against the first lifting beam 402 and the fixed beam 401 in the low position at the same time.

[0049] During normal feeding, the first lifting beam 402 is lowered to a low position. At this time, the top heights of the first lifting beam 402 and the fixed beam 401 are equal and not higher than the height of the highest points of the first fixed roller 201 and the second fixed roller 301, so as to avoid excessive friction between the plastic grille and the first lifting beam 402 and the fixed beam 401. The first feeding roller group 2 and the second feeding roller group 3 feed at the same speed. The servo encoder of the servo motor controls the speed. After feeding to a certain length, the feeding is stopped. At this time, the second lifting drive mechanism 405 drives the second lifting beam 403 to descend. The U-shaped opening of the second lifting beam 403 presses the plastic grille against the first lifting beam 402 and the fixed beam 401 at the same time, pressing and fixing the plastic grille, so as to facilitate the cutting assembly 5 to cut the grille. After the cutting is completed, the second lifting drive mechanism 405 drives the second lifting beam 403 to lift, and the first lifting drive mechanism 404 drives the first lifting beam 402 to lift, so that the first lifting beam 402 is slightly higher than the fixed beam 401, so as to avoid the plastic grille being affected by its own weight and bending downward. When feeding, it passes downward through the gap between the first lifting beam 402 and the fixed beam 401. After the first lifting beam 402 is lifted, the cutout position of the plastic grille is higher than the fixed beam 401. Even if there is a phenomenon of bending due to its own weight, problems can be avoided. After the first lifting beam 402 is lifted, it is higher than the highest point of the second fixed roller 301. The plastic grille is bent by its own weight and will naturally come between the second fixed roller 301 and the second pressure roller 302 and pass through them. The second feeding roller group 3 can realize automatic feeding, and then the first lifting drive mechanism 404 drives the first lifting beam 402 to descend to avoid excessive friction with the plastic grille.

[0050] Cutting assembly 5, such as Figure 3 , 4, 6, and 7, it is located below the fixed component 4. The cutting component 5 includes a lifting platform 501, a transverse platform 502, a cutting motor 503, and a saw blade 504. The lifting platform 501 is installed on the frame 1 through a third lifting drive mechanism 505. The transverse platform 502 is slidably installed on the lifting platform 501 through a slider 508 and a slide rail 509, and is driven to move by a transverse drive mechanism 506. The transverse platform 502 is long and has a plurality of cutting motors 503 evenly distributed along the length direction of the transverse platform 502. The cutting motor 503 is equipped with Saw blade 504, the lateral movement stroke of the lateral movement platform 502 is not less than the spacing of the cutting motor 503, when the lifting platform 501 moves to the high position, the highest point of the saw blade 504 can extend into the C-shaped cavity of the second lifting beam 403; generally, the maximum width of plastic gratings is 6m, and this solution can meet the maximum width of the winding work. There are 5 cutting motors 503, each with a spacing of 1.2m, and the lateral movement stroke of the lateral movement drive mechanism 506 is 1.3m, so the total cutting stroke is 6.1m, which can completely cover the cutting of all plastic gratings with a width of less than 6m. When cutting is required, the fixed component 4 has a fixed stroke, the traverse platform 502 moves to the leftmost end, and the lifting platform 501 rises to the highest point. At this time, the saw blade 504 extends into the C-shaped cavity of the second lifting beam 403. At this time, the five saw blades 504 simultaneously cut five cuts on the plastic grille, and then the traverse platform 502 moves 1.3m to the rightmost end, and the five cuts are horizontally elongated until they overlap into a 6.1m cut. After the cutting is completed, the cutting component 5 is reset, that is, the lifting platform 501 descends, and the traverse platform 502 moves to the leftmost end. Using multiple cutting motors 503 for simultaneous cutting shortens the stroke and improves the processing efficiency compared with a single cutting motor 503.

[0051] Winding components, such as Figure 8-9 As shown, it includes a fixed winding component 6, a dynamic winding component 7, and a tape packaging component. This solution does not make much improvement to the winding component. The present invention is based on the company's existing invention CN115180441B, a plastic grid coreless automatic winding device, and mainly improves the feeding component. For easy understanding, the winding component is also briefly described in terms of structure and function.

[0052] like Fig. 9As shown, the fixed winding assembly 6 includes a fixed winding support 601, a fixed winding roller 602, and a third rotary drive mechanism 603.

A plurality of rubber wheels are installed on the fixed winding roller 602 at intervals. The rubber wheels of the two fixed winding rollers 602 are staggered with each other, and partially intersect in the projection along the axial direction of the fixed winding roller 602. One end of one of the fixed winding rollers 602 is connected to the third rotary drive mechanism 603, and the third rotary drive mechanism 603 is located on one side of the fixed winding support 601. The other ends of the two fixed winding rollers 602 are connected through the first transmission member 604, and the first transmission member 604 is fixed on the other side of the fixed winding support 601.

[0053] like Figure 8 As shown, the dynamic winding assembly 7 includes a dynamic winding support 701, a dynamic winding roller 702, a fourth rotating drive mechanism 703, and a fourth lifting drive mechanism 704.

Two dynamic winding rollers 702 are provided, which are rotatably arranged on the dynamic winding support 701. A plurality of rubber wheels are installed on the dynamic winding roller 702 at intervals. The rubber wheels of the two dynamic winding rollers 702 are staggered with each other, and partially intersect in the projection along the axial direction of the dynamic winding roller 702. The rubber wheels of the upper and lower adjacent fixed winding rollers 602 and the dynamic winding roller 702 are also staggered. One end of one of the dynamic winding rollers 702 is connected to the fourth rotating drive mechanism 703, and the fourth rotating drive mechanism 703 is located on one side of the dynamic winding support 701. The other ends of the two dynamic winding rollers 702 are connected through the second transmission member 705, and the second transmission member 705 is fixed on the other side of the dynamic winding support 701.

[0054] The adhesive tape packaging assembly is installed in the gap between the two rubber wheels (not shown in the figure).

[0055] When winding, the dynamic winding assembly 7 descends, and the two fixed winding rollers 602 and the two dynamic winding rollers 702 enclose an area with only an opening on the left side (with the right view as a reference). The plastic grille enters from the opening, and all the fixed winding rollers 602 and the dynamic winding rollers 702 rotate clockwise, guiding the plastic grille to rotate counterclockwise against the rubber wheel and be wound into a coil. As the diameter of the coil increases, the dynamic winding assembly 7 slowly rises, and finally the tape packaging assembly wraps the tape, and finally the dynamic winding assembly 7 rises to the maximum to facilitate unloading.

[0056] In actual application, the lifting platform 501 is in the shape of a long rectangular frame, the third lifting drive mechanism 505 is an oil cylinder, and the third lifting drive mechanism 505 is provided with two groups, which are respectively located below the two ends of the lifting platform 501, and the transverse movement platform 502 is located on the inner side of the vertical projection of the square shape of the lifting platform 501. A plurality of triangular brackets 507 are fixedly installed on the transverse movement platform 502, and the two ends of the triangular brackets 507 extend out from the transverse movement platform 502 and are connected with sliders 508. A plurality of slide rails 509 are provided on the lifting platform 501, and the sliders 508 and the slide rails 509 are slidably matched. The transverse movement platform 502 is slidably connected with the two sides of the lifting platform 501 through the triangular brackets 507, and has stronger stability. In addition, strip limit blocks are installed on the side panels 101 of the frame 1 to limit the two sides of the lifting platform 501 to ensure that the lifting platform 501 can be lifted and lowered stably.

The stroke of the screw assembly 5062 is greater than the spacing of the cutting motor 503. The use of the transverse driving motor 5061 in conjunction with the screw assembly can achieve very detailed control, and can smoothly and steadily control the transverse speed of the transverse platform 502.
