Technical Field
[0001] This utility model relates to the technical field of roll winding equipment, specifically a roll winding and edge trimming device. Background Technology
[0002] A roll rewinder (also known as a winding machine or roll winding device) is a device specifically designed for collecting, sorting, and winding thin rolls of materials (such as metal strips, plastic films, paper, and fabrics) into rolls. It is widely used in industries such as metal processing, plastic film manufacturing, textiles, and papermaking.
[0003] In the existing technology, some of the roll winding machines used for winding have raised edges, and there is no edge trimming device to trim the edges of the roll. The raised edges will cause uneven tension at both ends of the roll. During the winding process, this will cause the roll to be skewed, wrinkled or irregularly shaped, affecting the appearance of the product and causing defects in the roll during subsequent processing.
[0004] Therefore, we propose a device for winding and trimming roll materials. Utility Model Content

The two coarse adjustment rod covers are respectively set at the adjacent ends of the two trimming device mounting plates. The blade is installed inside the dovetail slide rail. A waste collection box is set at the adjacent ends of the two trimming device mounting plates. A linear bearing is set at the adjacent ends of the two trimming device mounting plates.
[0008] Among them, the two linear bearings are fixedly connected to a fixing rod at their adjacent ends.
[0009] A trimming knife is fixedly connected to the right side of the trimming device mounting plate.
[0010] The edge-cutting device mounting plate is rotatably connected to both the left and right sides by a handwheel, and the edge-cutting device mounting plate is rotatably connected to a guide roller inside.
[0011] Among them, coarse adjustment rods are fixedly connected to the adjacent ends of the two handwheels, and lead screws and nuts are provided at the adjacent ends of the two coarse adjustment rods.

[0021] 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.
[0022] Example 1
[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a roll material winding and edge trimming device, including a winding pre-unit 1. The winding pre-unit 1 is designed to facilitate the fixing of the edge trimming device mounting plate 2. Two edge trimming device mounting plates 2 are fixedly connected to the front side of the winding pre-unit 1. The edge trimming device mounting plates 2 are designed to facilitate the installation of the edge trimming device. A motor 5 is fixedly connected inside each of the two edge trimming device mounting plates 2. The motor 5 is designed to drive the bottom knife 4. The driving end of each of the two motors 5 is provided with a bottom knife 4. The bottom knife 4 is designed to cooperate with the blade 8 to trim the edge of the roll material. A winding mechanism for winding the roll material is provided inside the two edge trimming device mounting plates 2.
[0024] The winding mechanism includes a dovetail slide rail 6, a coarse adjustment rod cover 7, a blade 8, and a linear bearing 11. The dovetail slide rail 6 is fixedly connected to the right side of the edge trimming device mounting plate 2. The dovetail slide rail 6 is designed to facilitate the installation of the blade 8. Two coarse adjustment rod covers 7 are respectively set at the near ends of the two edge trimming device mounting plates 2. The coarse adjustment rod covers 7 are designed to protect the coarse adjustment rod 15. The blade 8 is installed inside the dovetail slide rail 6. The blade 8 is designed to cooperate with the bottom blade 4 to trim the edge of the roll material. A waste collection box 9 is set at the near ends of the two edge trimming device mounting plates 2. The waste collection box 9 is designed to collect the cut waste material from the roll material. A linear bearing 11 is set at the near ends of the two edge trimming device mounting plates 2. The linear bearing 11 is designed to connect the fixing rod 10.
[0025] Two linear bearings 11 are fixedly connected to a fixing rod 10 at their adjacent ends. The fixing rod 10 is designed to facilitate the connection of the two cutting device mounting plates 2.
[0026] The right side of the edge trimming device mounting plate 2 is fixedly connected to an edge trimming knife 12, which is designed to trim the edges of the roll material.
[0027] Handwheel 13 is rotatably connected to both the left and right sides of the edge trimming device mounting plate 2. The handwheel 13 is designed to rotate the coarse adjustment rod 15 to move the lead screw nut 16. The inside of the edge trimming device mounting plate 2 is rotatably connected to the guide roller 14. The guide roller 14 is designed to cooperate with the guide roller 20 to guide the roll material.
[0028] Both handwheels 13 are fixedly connected to coarse adjustment rods 15 at their adjacent ends, which can move the lead screw nut 16. When the width of the roll material changes significantly, it can directly drive the blade 8 to move over a wide range. Both coarse adjustment rods 15 are provided with lead screw nuts 16 at their adjacent ends, which can move the lead screw nut 16. When the width of the roll material changes significantly, it can directly drive the blade 8 to move over a wide range.
[0029] A movable plate 17 is fixedly connected to the right side of the trimming device mounting plate 2. Two movable plates 17 are fixed to the trimming blade 12. A clamping seat 18 is fixedly connected to the outer side of the movable plate 17. The clamping seat 18 is fixed to the movable plate 17. The circular hole on it is split, with a through hole on one side and a threaded hole on the other side. The locking handwheel 19 can tighten the circular hole to a certain extent to lock the fixing rod 10 and prevent it from sliding. The top of the trimming device mounting plate 2 is equipped with a locking handwheel 19. The inside of the trimming device mounting plate 2 is equipped with a second guide roller 20. The second guide roller 20 is designed to cooperate with the first guide roller 14 to facilitate the conveying of the roll material. Because the winding edge must be kept neat, the trimming device must be adjusted every time the material is changed, because the width of each roll of material will change. When there are significant changes, directly loosen the locking handwheel 19, rotate the coarse adjustment lever 15 to move the lead screw nut 16, and the rotation of the coarse adjustment lever 15 will also drive the adjustment of the blade 8. When the blade 8 reaches the approximately appropriate position, lock the locking handwheel 19. Then slowly adjust the edge trimming blade 12 until the blade 8 is in the most suitable position, and finally lock it so that the edge trimming blade 12 can no longer move. By using the roll winding and edge trimming device to trim the edges of the roll being wound on the roll winding machine, it is possible to avoid uneven tension at both ends of the roll caused by the curled edges, reduce the occurrence of skewing, wrinkles or irregular shapes during roll winding, and improve the product appearance.
