It mainly consists of an unwinding mechanism, a cutting mechanism, a winding mechanism, as well as various functional rollers, tension control, web correction control, and detection devices. The working principle of this equipment is that the film raw material is released from the unwinding mechanism, and after a series of processing and web correction, it enters the cutting mechanism for precise slitting. Finally, the winding mechanism winds it into a standard film roll.

[0003] When the film enters the cutting process through the unwinding device, the lack of an edge guide device leads to frequent material breaks and edge damage, which seriously affects the quality of the film. Utility Model Content

Detailed Implementation

[0017] 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.

[0018] Please see Figure 1 , Figure 2 and Figure 3 The figure shows a slitting edge guide device, including a plate 1 and a guide structure 2 set on the front end. The guide structure 2 includes a pad 201. A slide rail 207 is fixedly connected to the plate 1. U-shaped sliders 202 are fixedly connected to the rear end faces of both sides of the pad 201. The U-shaped sliders 202 are slidably connected to the slide rail 207. Two F-shaped brackets 206 are fixedly connected to the front end of the pad 201. Two rollers 204 are provided between the two F-shaped brackets 206. A mandrel 208 is fixedly sleeved inside the roller 204. The two ends of the mandrel 208 rotate through the F-shaped brackets 206. A bearing 203 is rotately sleeved at the through end. The bearing 203 is fixedly installed on the outer side of the F-shaped bracket 206.

[0019] It is worth noting that when the original film enters the cutting process through the unwinding device, the film edge material is mainly fed into the edge material channel by the two rollers 204, relying on the bearings 203 at both ends of the mandrel 208 for stable rotation. The guide structure 2 ensures stable guidance of the film during the cutting process. The pad 201 is slidably connected to the slide rail 207 through the U-shaped slider 202, allowing for flexible position adjustment to accommodate films at different locations, thus improving the equipment's versatility and flexibility. Furthermore, the combined design of the F-type bracket 206 and the rollers 204 provides stable support and a rotation path for the film edge material. The mandrel 208 fixedly fitted inside the rollers 204, and the bearings 203 at both ends of the mandrel 208 that rotate through the F-type bracket 206 and are fitted with it, ensure the smoothness and stability of the rollers 204 during rotation, effectively preventing jamming or tearing of the film edge material during the cutting process and guaranteeing product quality.

[0020] Please see Figure 1 The substrate 1 has a plurality of mounting holes 101. These mounting holes 101 facilitate the secure mounting of the substrate 1 onto the corresponding equipment or frame. The layout of the mounting holes 101 is reasonable, which not only facilitates installation and disassembly, but also helps to adjust the position of the substrate 1, thereby improving the practicality and flexibility of the equipment.

[0021] Please refer to Figure 1The slide rail 207 has an I-shaped cross section. The two inner sides of the U-shaped slider 202 are fixedly connected to the slide bar, which is slidably connected to the side of the slide rail 207. The I-shaped design of the slide rail 207 provides sufficient strength and rigidity to withstand the pressure generated by the film edge material on the pad 201 during the cutting process, ensuring the stable operation of the entire guide structure 2.

[0022] See Figure 1 and Figure 3 Several triangular reinforcing frames 205 are fixedly connected to adjacent sides of the two F-shaped brackets 206. One side wall of the triangular reinforcing frame 205 is fixedly connected to the front end face of the pad 201. The use of the triangular reinforcing frame 205 is based on the stability principle of triangles, which effectively disperses the impact force that may be generated during the cutting process, and further ensures the smooth transmission of film edge material during cutting. At the same time, the fixed connection between the triangular reinforcing frame 205 and the front end face of the pad 201 enables the F-shaped bracket 206 to be effectively supported when subjected to pressure, avoiding deformation or displacement of the F-shaped bracket 206, thereby ensuring cutting accuracy and product quality.

[0023] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The limiting structure 3 includes a handle 302 and a support rod 303. The support rod 303 is fixedly connected to the front end of both sides of the pad 201. The support rod 303 has a countersunk hole 304 inside its outer end. An insert rod 305 is slidably connected inside the countersunk hole 304. The side wall of the outer end of the support rod 303 has a notch 308 communicating with the countersunk hole 304. One end of the handle 302 is inserted into the notch 308. The inserted end is rotatably connected to one end of the insert rod 305 through a pin 306. The other end of the insert rod 305 slides through the pad 201. The front end face of the slide rail 207 has a number of locking holes 301.

[0024] When the guide structure 2 needs to be fixed to the slide rail 207, simply move the lever handle 302 to drive the insertion rod 305 to slide in the countersunk hole 304, and after passing through the pad plate 201, it will be inserted into the corresponding locking hole 301 to complete the limiting and fixing. The operation is simple and quick.

[0025] See Figure 4 A rubber damping block 307 is fixedly connected to one end of the insertion rod 305 near the handle 302. The rubber damping block 307 can dampen and increase the friction, ensuring that the insertion rod 305 can be stably set when the handle 302 is turned, thus improving the stability of the limiting structure 3.

[0026] Working principle: When the original film enters the cutting process through the unwinding device, the film edge material is mainly fed into the edge material channel by the two rollers 204, relying on the bearings 203 at both ends of the mandrel 208 for stable rotation. The guide structure 2 is set to achieve stable guidance of the film during the cutting process. The pad 201 is slidably connected to the slide rail 207 through the U-shaped slider 202, which can be flexibly adjusted to adapt to the film that needs to pass through, thus improving the versatility and flexibility of the equipment. Secondly, the combination design of the F-type bracket 206 and the rollers 204 provides stable support and rotation path for the film edge material. The mandrel 208 fixedly sleeved inside the roller 204, and the bearings 203 at both ends of the mandrel 208 rotating through the F-type bracket 206 and sleeved thereon, ensure the smoothness and stability of the roller 204 during rotation.
