[0002] Bag making machines are an indispensable and important equipment in the modern packaging industry and are widely used in packaging production lines in the food, pharmaceutical, daily necessities and other industries. Among them, the cutting mechanism, as one of the core components of the bag making machine, plays a vital role. It is responsible for accurately dividing the continuous film bags into individual packaging products during the bag making process to ensure that each product has a complete shape and size.

[0003] Traditional cutting tools are mostly fixed blades. This design can meet basic cutting needs in specific occasions. However, fixed blades often face the problem of insufficient flexibility in the cutting process. Due to their fixed structure, they are difficult to adapt to cutting objects of different materials, thicknesses and shapes. At the same time, due to their relatively single cutting method, there are certain limitations in cutting efficiency. In view of the above problems, a roller cutting mechanism for a bag making machine is proposed. Utility Model Content

[0006] As mentioned above, the lifting rod passes through the slide slot and is connected to the transmission block, the transmission block is slidably connected to the top of the cutting frame, the cutting knife is rotatably connected to the bottom of the linkage frame, the cutting knife forms a lifting structure with the transmission block through the cooperation of the linkage frame and the lifting rod, and the protective plate covers the outside of the cutting knife and the linkage frame.

[0007] As mentioned above, the top of the fixed block is fixed to the bottom of the cutting frame, the guide rail is slidably connected to the telescopic plate, and the cutting knife forms a sliding structure with the fixed block through the cooperation between the linkage frame, the telescopic plate and the guide rail.

[0008] As mentioned above, a feeding platform is provided at the bottom of the feeding port, and one side of the inner end of the feeding platform is fixed to the outer wall of the device body, a cutting groove is penetrated through one side of the outer surface of the feeding platform, and a guide plate is fixedly connected to the inner surface of the cutting groove, and a placement block is fixedly connected to the outer surface of the bottom end of the feeding platform, and a clamping groove is provided on the inner surface of the placement block, and a fixing shaft is movably connected to the inner wall of the clamping groove, a scraper is fixedly connected to the inner surface of one side of the fixing shaft, and an inclined groove is provided on the top side of the scraper.

[0009] As mentioned above, the guide plates are symmetrically opened on both sides of the inner wall of the cutting groove, the cutting groove is arranged directly below the cutting knife, the cutting groove is opened horizontally through the outside of one side of the feeding table, and the guide plates are arranged to be inclined downward at 60°.

[0010] As mentioned above, the placement blocks are symmetrically distributed on both sides of the bottom of the cutting groove, the scraper is clamped in the placement block through the clamping groove and the clamping shaft, and the outer surfaces of both sides of the cutting knife are tightly fitted with the inner surface of the scraper.

[0011] As mentioned above, a connecting end is fixedly connected to the outer bottom of the material transfer table, a connecting shaft is snap-connected to the bottom of the connecting end, a supporting frame is fixedly connected to the outside of the bottom side of the connecting shaft, and the other side bottom of the supporting frame is fixed to the outer side of the device body.

[0012] Compared with the prior art, the rolling knife cutting mechanism of the bag making machine has the following beneficial effects:

[0013] 1. When the utility model is working, the transmission block drives the lifting rod to drive the linkage frame at the bottom to slide along the inside of the slide slot, and at the same time, the linkage frame performs lifting and lowering movement in the slide slot through the lifting rod, and the lifting and lowering action is transmitted to the cutting knife through the linkage frame, so that the cutting knife can move up and down as needed to meet the cutting needs of materials of different thicknesses or types. When the cutting knife is lifted or lowered, the linkage frame drives the telescopic plate to slide under the guidance of the guide rail, so that the cutting knife can move in the horizontal direction to achieve horizontal cutting of the material. The guide rail limits the movement of the horizontally moving cutting knife through the telescopic plate, thereby ensuring stability during cutting. Finally, when the cutting knife is working, the protective plate covers the outside of the cutting knife and the linkage frame to prevent the cutting knife from being exposed to the environment, thereby protecting the safety of the operator.

[0014] 2. When the utility model starts working, the material to be cut is conveyed from the feed port to the feed table and moves forward along the surface of the feed table. When the material moves to the position of the cutting groove, the cutting knife starts to rotate at high speed and moves toward the material. Since the guide plate is set to be inclined downward at 60°, when the cutting knife cuts the material, the material can slide down smoothly along the guide plate, ensuring smooth cutting. In the process of the cutting knife cutting the material, the scraper is engaged with the inside of the placement block through the card slot and the fixing shaft, and its inner surface is tightly fitted with the outer surfaces on both sides of the cutting knife. In this way, when the cutting knife cuts the material, the scraper can effectively scrape off the residual material attached to the cutting knife, ensuring that the cutting knife always remains clean, thereby improving the cutting accuracy and efficiency.

[0015] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and will be apparent to those skilled in the art based on the following examination and study, or may be taught from the practice of the present invention to some extent.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, the utility model provides a technical solution: a bag making machine rolling knife cutting mechanism, including a device body 1, a feeding port 101 is provided on the outside of one side of the device body 1, a fixing plate 102 is arranged on the top of the feeding port 101, and the fixing plate 102 is fixed to the outer wall of the device body 1, a cutting frame 2 is fixedly connected to the outer side of the fixing plate 102, a protective plate 201 is fixedly connected to the bottom end of the cutting frame 2, a slide groove 202 is provided at the inner center of the cutting frame 2, a transmission block 203 is movably connected to the top of the cutting frame 2, a lifting rod 204 is fixedly connected to the bottom of the transmission block 203, a linkage frame 205 is fixedly connected to the bottom of the lifting rod 204, and a telescopic plate 206 is fixedly connected to both sides of the top of the linkage frame 205, a guide rail 207 is movably connected to the top of the telescopic plate 206, and a fixed block 208 is fixedly connected to the top of the guide rail 207. The bottom of 205 is movably connected with a cutting knife 209, the bottom of the feeding port 101 is provided with a feeding platform 3, and one side of the inner end of the feeding platform 3 is fixed to the outer wall of the device body 1, a cutting groove 301 is penetrated through one side of the outer surface of the feeding platform 3, the inner surface of the cutting groove 301 is fixedly connected with a guide plate 302, the outer surface of the bottom end of the feeding platform 3 is fixedly connected with a placing block 303, the inner surface of the placing block 303 is provided with a slot 304, the inner wall of the slot 304 is movably connected with a fixing shaft 305, the inner surface of one side of the fixing shaft 305 is fixedly connected with a scraper 306, the top side of the scraper 306 is provided with an inclined groove 307, the outer bottom of the feeding platform 3 is fixedly connected with a connecting end 4, the bottom of the connecting end 4 is engaged with a connecting shaft 401, the bottom side of the connecting shaft 401 is fixedly connected to a support frame 402, and the other side of the support frame 402 is fixed to the outside of the device body 1.

[0024] According to the overall structure of the device, the transmission block 203 drives the lifting rod 204 to drive the linkage frame 205 at the bottom to slide along the inside of the slide groove 202. At the same time, the linkage frame 205 is lifted and lowered in the slide groove 202 through the lifting rod 204. The lifting action is transmitted to the cutting knife 209 through the linkage frame 205, so that the cutting knife 209 can move up and down as needed to meet the cutting requirements of materials of different thicknesses or types. When the cutting knife 209 is lifted and lowered, the linkage frame 205 drives the telescopic plate 206 to slide under the guidance of the guide rail 207, so that the cutting knife 209 can move in the horizontal direction to achieve transverse cutting of the material. The guide rail 207 moves the transversely moving cutting knife 209 through the telescopic plate 206. The dynamic limit ensures the stability during cutting. Finally, when the cutting knife is working, the protective plate 201 covers the outside of the cutting knife 209 and the linkage frame 205 to prevent the cutting knife 209 from being exposed to the environment, thereby protecting the safety of the operator. When the material moves to the position of the cutting groove 301, the cutting knife 209 starts to rotate at high speed and moves toward the material. Since the guide plate 302 is set to be inclined downward at 60°, when the cutting knife 209 cuts the material, the material can slide smoothly along the guide plate 302. In the process of the cutting knife 209 cutting the material, the scraper 306 can effectively scrape off the residual material attached to the cutting knife 209, ensuring that the cutting knife 209 always remains clean, thereby improving the cutting accuracy and efficiency.

[0025] like Figure 1-5 As shown, the lifting rod 204 passes through the slide groove 202 and is connected to the transmission block 203, the transmission block 203 is slidably connected to the top of the cutting frame 2, the cutting knife 209 is rotatably connected to the bottom of the linkage frame 205, and the cutting knife 209 forms a lifting structure with the transmission block 203 through the cooperation of the linkage frame 205 and the lifting rod 204. The protective plate 201 is covered on the outside of the cutting knife 209 and the linkage frame 205. The top of the fixed block 208 is fixed to the bottom end of the cutting frame 2, the guide rail 207 is slidably connected to the telescopic plate 206, and the cutting knife 209 forms a sliding structure with the fixed block 208 through the cooperation between the linkage frame 205, the telescopic plate 206 and the guide rail 207.

[0026] The transmission block 203 drives the lifting rod 204 to drive the linkage frame 205 at the bottom to slide along the inside of the slide groove 202. At the same time, the linkage frame 205 is lifted and lowered in the slide groove 202 through the lifting rod 204. The lifting action is transmitted to the cutting knife 209 through the linkage frame 205, so that the cutting knife 209 can move up and down as needed to meet the cutting needs of materials of different thicknesses or types. When the cutting knife 209 is lifted and lowered, the linkage frame 205 drives the telescopic plate 206 to slide under the guidance of the guide rail 207, so that the cutting knife 209 can move in the horizontal direction to achieve horizontal cutting of the material. The guide rail 207 limits the movement of the horizontally moving cutting knife 209 through the telescopic plate 206 to ensure stability during cutting. Finally, when the cutting knife is working, the protective plate 201 covers the outside of the cutting knife 209 and the linkage frame 205 to prevent the cutting knife 209 from being exposed to the environment, thereby protecting the safety of the operator.

[0027] like Figure 1-5 As shown, the guide plates 302 are symmetrically opened on both sides of the inner wall of the cutting groove 301, the cutting groove 301 is arranged directly below the cutting knife 209, and the cutting groove 301 is horizontally opened through one side of the outside of the feeding platform 3. The guide plate 302 is inclined downward at 60°, and the placement blocks 303 are symmetrically distributed on both sides of the bottom of the cutting groove 301. The scraper 306 is engaged with the inside of the placement block 303 through the card slot 304 and the fixing shaft 305, and the outer surfaces of both sides of the cutting knife 209 are tightly fitted with the inner surface of the scraper 306.

[0028] When the bag making machine starts working, the material to be cut is conveyed from the feed port 101 to the feed table 3 and moves forward along the surface of the feed table 3. When the material moves to the position of the cutting groove 301, the cutting knife 209 starts to rotate at high speed and moves toward the material. Since the guide plate 302 is set to be inclined downward at 60°, when the cutting knife 209 cuts the material, the material can slide down smoothly along the guide plate 302, ensuring smooth cutting. In the process of the cutting knife 209 cutting the material, the scraper is engaged with the inside of the placement block 303 through the card slot 304 and the fixing shaft 305, and its inner surface is tightly fitted with the outer surfaces of both sides of the cutting knife 209. In this way, when the cutting knife 209 cuts the material, the scraper 306 can effectively scrape off the residual material attached to the cutting knife 209, ensuring that the cutting knife 209 always remains clean, thereby improving the cutting accuracy and efficiency.

[0029] Working principle: First, the transmission block 203 drives the lifting rod 204 to drive the linkage frame 205 at the bottom to slide along the inside of the slide groove 202. At the same time, the linkage frame 205 is lifted and lowered in the slide groove 202 through the lifting rod 204. The lifting action is transmitted to the cutting knife 209 through the linkage frame 205, so that the cutting knife 209 can move up and down as needed to meet the cutting needs of materials of different thicknesses or types. When the cutting knife 209 is lifted and lowered, the linkage frame 205 drives the telescopic plate 206 to slide under the guidance of the guide rail 207, so that the cutting knife 209 can move in the horizontal direction to achieve transverse cutting of the material. The guide rail 207 limits the movement of the transversely moving cutting knife 209 through the telescopic plate 206 to ensure stability during cutting. Finally, when the cutting knife is working, the protective plate 201 covers the outside of the cutting knife 209 and the linkage frame 205 to prevent the cutting knife 209 from being exposed to the environment, thereby protecting the safety of the operator.

[0030] When the bag making machine starts working, the material to be cut is conveyed from the feed port 101 to the feed table 3 and moves forward along the surface of the feed table 3. When the material moves to the position of the cutting groove 301, the cutting knife 209 starts to rotate at high speed and moves toward the material. Since the guide plate 302 is set to be inclined downward at 60°, when the cutting knife 209 cuts the material, the material can slide down smoothly along the guide plate 302, ensuring smooth cutting. In the process of the cutting knife 209 cutting the material, the scraper 306 is engaged with the inside of the placement block 303 through the slot 304 and the fixing shaft 305, and its inner surface is tightly fitted with the outer surfaces of both sides of the cutting knife 209. In this way, when the cutting knife 209 cuts the material, the scraper 306 can effectively scrape off the residual material attached to the cutting knife 209, ensuring that the cutting knife 209 always remains clean.
