Technical Field

[0001] This utility model belongs to the technical field of film slitting machines, and in particular relates to a blade holder for a film slitting machine. Background Technology

[0002] The blade holder of a film slitting machine is an important component used to fix and support the blades, playing a key role in the film production process.

[0003] Existing film slitting machine knife holders are used by rotating rods to drive circular blades. However, the circular blades are usually fixed to the rotating rods by bolts or welding. When the circular blades are damaged, the entire knife holder needs to be disassembled, and then the rotating rod needs to be disassembled for subsequent replacement or maintenance. This method not only consumes a lot of labor, but also increases maintenance costs by replacing the rotating rod and the circular blades together. Therefore, we have proposed a knife holder for film slitting machines. Utility Model Content

[0004] The purpose of this invention is to provide a blade holder for a film slitting machine. By setting up an assembly component, when it is necessary to replace the circular blade, the screws on the arc plate are removed to release the circular blade from its fixation. Then, the circular blade can be pulled to remove it. The operation is simple and convenient, without the need to disassemble the entire blade holder. At the same time, this method can improve maintenance efficiency and reduce costs. It solves the problem that existing film slitting machine blade holders use a rotating rod to drive the circular blade. However, the circular blade is usually fixed to the rotating rod by bolts or welding. As a result, when the circular blade is damaged, it is necessary to disassemble the entire blade holder and then disassemble the rotating rod for subsequent replacement or maintenance work, which not only consumes a lot of labor but also increases maintenance costs.

Detailed Implementation

[0025] 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 scope of protection of the present utility model.

[0026] Please see Figure 1-5 As shown, this utility model is a knife holder for a film slitting machine, including a conveying roller 11, with connecting seats 111 rotatably connected to the left and right sides of the conveying roller 11, and a rotating rod 12 is provided above the conveying roller 11. The left and right sides of the rotating rod 12 are rotatably connected to the two connecting seats 111, and a plurality of assembly components 13 are provided on the outer surface of the rotating rod 12.

[0027] Assembly component 13 includes a movable ring 131, with circular blades 133 at both the top and bottom. The outer surface of the movable ring 131 has several threaded holes 311, and positioning holes 312 are also provided at both the top and bottom. Arc-shaped plates 331 are fixedly connected to the left and right sides of the circular blades 133. Two insertion holes 332 are provided inside the arc-shaped plates 331. A positioning block 333 is fixedly connected to the bottom of the circular blades 133. By using assembly component 13, when the circular blades 133 need to be replaced, the screws on the arc-shaped plates 331 are removed to release the circular blades 133, and then the circular blades 133 can be pulled to disassemble them. The operation is simple and convenient, eliminating the need to disassemble the entire blade holder. This method also improves maintenance efficiency and reduces costs. The rotating rod 12 has a hollow interior. A fixed rod 121 is fixedly connected to the inner wall of the rotating rod 12. A groove 122 is opened on the front of the rotating rod 12. An inner connecting ring 132 is slidably connected to the outer surface of the fixed rod 121. The groove 122 can limit the inner connecting ring 132, so that the inner connecting ring 132 and the moving ring 131 move in a linear manner. The front of the inner connecting ring 132 passes through the rotating rod 12 and extends to the inner wall of the moving ring 131 for fixed connection. The outer surface of the inner connecting ring 132 contacts the inner wall of the groove 122, and the inner side of the moving ring 131 contacts the outer surface of the rotating rod 12. A limit groove 123 is opened at the top of the rotating rod 12. After the moving ring 131 is adjusted, the bolt 341 is rotated clockwise to make the circular limit shaft 342 move upward. The surface of the circular limit shaft 342... The moving ring 131 is fixed by tightly adhering to the inner wall of the limiting groove 123, thereby fixing the fixing block 134. The inner side of the circular blade 133 and the inner side of the arc plate 331 are both in contact with the outer surface of the moving ring 131. The insertion hole 332 corresponds to the threaded hole 311. The positioning block 333 is inserted into the positioning hole 312. A screw is inserted into the insertion hole 332 and threaded into the threaded hole 311. The circular blade 133 is inserted into the positioning hole 312 on the moving ring 131 through the positioning block 333 at the bottom. At this time, the circular blade 133 and the arc plate 331 are in contact with the moving ring 131. Then, the screw is inserted into the insertion hole 332 on the arc plate 331. The screw is then threaded into the threaded hole 311 using a tool. The circular blade 133 is then fixed and the installation is complete. The moving ring 131 is on the right. A fixing block 134 is fixedly connected to the side. The fixing block 134 has a threaded hole inside, and a bolt 341 is threadedly connected to the inner wall of the threaded hole. A circular limiting shaft 342 is fixedly connected to the bottom of the bolt 341. By setting a moving ring 131, specifically by rotating the bolt 341 counterclockwise, the circular limiting shaft 342 moves slightly downward, releasing the fixing of the fixing block 134. Then, by pushing and pulling the moving ring 131, the position of the circular blade 133 is adjusted, which can control different cutting widths to meet different needs during cutting. The bottom of the circular limiting shaft 342 extends into the limiting groove 123. The outer surface of the circular limiting shaft 342 contacts the inner wall of the limiting groove 123. The limiting groove 123 is set in an inverted T shape. The circular limiting shaft 342 and the limiting groove 123 are adapted to each other to play a limiting role.

[0028] One specific application of this embodiment is:

[0029] The circular blade 133 is inserted into the positioning hole 312 on the moving ring 131 via the positioning block 333 at the bottom. At this time, the circular blade 133 and the arc plate 331 are in contact with the moving ring 131. Then, a screw is inserted into the insertion hole 332 on the arc plate 331, and a tool is used to thread the screw into the threaded hole 311 to fix the circular blade 133 and complete the installation. Since the circular blade 133 is divided into two, the two circular blades 133 form a circle after installation, which facilitates the installation work. When it is necessary to replace the circular blade 133, the screw on the arc plate 331 is removed to release the fixing of the circular blade 133. Then, the circular blade 133 can be pulled to remove it. The operation is simple and convenient, without the need to disassemble the entire blade holder. At the same time, this method can improve maintenance efficiency. The process is efficient and cost-effective. By rotating the bolt 341 counterclockwise, the circular limiting shaft 342 moves slightly downward, releasing the fixing block 134. Then, the moving ring 131 is pushed and pulled, and the circular limiting shaft 342 slides within the limiting groove 123. The moving ring 131 drives the inner connecting ring 132 to slide on the fixing rod 121, allowing the position of the moving ring 131 to be adjusted. This adjusts the position of the circular blade 133, enabling control of different cutting widths to meet various cutting requirements. After adjustment, rotating the bolt 341 clockwise moves the circular limiting shaft 342 upward, causing its surface to press tightly against the inner wall of the limiting groove 123, thus fixing the fixing block 134 and the moving ring 131. Subsequent cutting operations can then proceed.
