Description

Technical Field

[0001] This utility model relates to the field of film cutting equipment technology, and specifically to an adaptive edge film cutting device. Background Technology

[0002] In the production of thin-plate materials such as those used in home appliance color printing, due to the thinness and low yield strength of these plates, products require processes such as applying aluminum film or protective film to the surface. Excess film on the sides of the finished product needs to be cut off to ensure product quality. Traditional fixed-edge cutting devices typically use fixed cutting blades installed on both sides of the production line to cut the edges of the thin plates. However, in actual production, the thin plates (such as steel plates) on the production line often deviate from their designated positions, resulting in incomplete edge cutting, low cutting accuracy, and a high product defect rate. As customers' requirements for product quality continue to increase, this problem often leads to numerous defective products and rework, impacting production efficiency.

[0003] The shortcomings of existing technologies are mainly reflected in the following aspects: 1. Traditional fixed cutting devices cannot automatically correct their position by following the deviation of the thin plate. When the thin plate deviates, the cutting tool position is fixed, resulting in uneven cutting edges or missed cuts, poor cutting accuracy, and inability to meet high precision requirements; 2. Fixed devices are prone to squeezing the sides of the thin plate when it deviates, causing deformation or even scrapping of the thin plate, especially suitable for industries with thin plates that are thin and have low strength; 3. Existing devices lack flexible clamping function, and the clamping force is not adjustable, making it unable to adapt to thin plates of different thicknesses and materials, resulting in a narrow range of applications; 4. Traditional devices have poor stability during the movement of the thin plate, and the thin plate is prone to shaking, further affecting the cutting accuracy; 5. The positioning and cutting components of existing devices have complex structures, are inconvenient to adjust, have high maintenance costs, and cannot achieve real-time automatic correction, resulting in low overall production efficiency.

[0004] In summary, existing thin-film cutting devices suffer from technical drawbacks in practical applications, including low cutting accuracy, inability to automatically correct offsets, susceptibility to thin-plate deformation, poor stability, narrow applicability, and high maintenance costs. There is an urgent need for an adaptive cutting device that can automatically follow the offset of the thin plate and possesses flexible clamping capabilities to improve production efficiency and product quality. Utility Model Content

[0005] The technical problem this invention aims to solve is to overcome the shortcomings of the prior art and provide an adaptive edge-cutting device with a reasonable structure, high cutting precision, and the ability to automatically follow the offset of thin plates. Another objective of this invention is to provide a cutting device with flexible clamping function, good stability, and wide applicability, which can effectively prevent thin plate deformation and improve production efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An adaptive edge film cutting device includes a film, characterized in that: it includes a movable platform, with rollers arranged on both sides of the movable platform, and film cutting devices installed at both ends of the movable platform. The film cutting devices are horizontally and movably connected to the movable platform. A positioning pin is fixed on the movable platform, and the positioning pin is located between the film cutting devices. Hook springs are respectively provided between the film cutting devices at both ends and the positioning pins. The film cutting device includes a fixed frame, a positioning component, and a cutting blade assembly. The positioning component is fixed on the fixed frame. The positioning component includes a positioning wheel and a movable shaft. The movable shaft is fixed to the fixed frame, and the positioning wheel is movably connected to the movable shaft. The cutting blade assembly includes a crank, with a pin arranged between the crank and the fixed frame. A cutting blade is installed at one end of the crank. The adaptive edge-cutting device of this invention is suitable for various online production sites where thin plates are cut / trimmed on both sides. The stability of the thin plate during movement is maintained by the rollers on the movable table. The positioning component is always in contact with the thin plate under the elastic force of the hook spring. When the thin plate deviates, the positioning wheel drives the cutting device to move horizontally on the movable table, realizing real-time automatic correction of the cutting position. The cutting blade assembly is connected by a crank and a pin to achieve flexible cutting, avoid extrusion deformation, and effectively improve cutting accuracy and production efficiency.

[0008] Furthermore, the surface of the idler roller is made of an antistatic material, which can prevent the thin plate from generating static electricity during movement and improve stability.

[0009] Furthermore, the gap between the positioning wheel and the movable shaft is adjustable, and by adjusting the gap, it can adapt to thin plates of different thicknesses to achieve flexible clamping.

[0010] Furthermore, the gap between the positioning wheel and the movable shaft is horizontal with the top of the idler roller, ensuring uniform contact between the positioning assembly and the thin plate and improving the correction accuracy.

[0011] Furthermore, both the crank and the cutter are at a certain angle to the horizontal line. This angle design can optimize the cutting path and reduce cutting resistance.

[0012] Furthermore, the hook spring is an adjustable length spring. By adjusting the spring length through a ratchet or similar mechanism, the magnitude of the force can be changed to adapt to the flexibility requirements of different thin sheet materials.

[0013] Furthermore, the bottom of the movable platform is equipped with a linear track slider to realize the horizontal movable connection of the film cutting device, thereby improving the smoothness and accuracy of movement.

[0014] Compared with existing film cutting devices, this invention has at least the following advantages:

[0015] 1. The adaptive edge film cutting device provided by this utility model achieves a follow-up function through the cooperation of hook spring and positioning component. When the thin plate deviates, the positioning wheel drives the film cutting device to automatically correct its position on the movable table, avoiding the problem of incomplete cutting of traditional fixed devices and improving cutting accuracy. At the same time, the added support roller maintains the stability of the thin plate and prevents shaking, further improving the cutting quality.

[0016] 2. This device has a flexible clamping function, the gap between the positioning wheel and the movable shaft is adjustable, and the hook spring force is adjustable, which avoids the side of the thin plate being squeezed and deformed. It is suitable for the thin plate industry with thin thickness and low strength. Compared with traditional devices, it can reduce the scrap rate by more than 50%.

[0017] 3. The cutting blade assembly adopts a crank and pin movable structure, which optimizes the cutting angle, reduces resistance, simplifies the overall structure, facilitates maintenance, and reduces production costs. It can be widely used in online production fields such as home appliance color printing boards to improve production efficiency. Attached Figure Description
