Description

Technical Field

[0001] This utility model relates to the field of packaging bag cutting technology, specifically a cutting device for packaging bag production. Background Technology

[0002] Packaging bags are bags used to package goods and are widely used in daily life and business activities. Packaging bag production is a relatively complex process. Common packaging materials include plastic, and the production process requires cutting the packaging bags.

[0003] However, existing technologies still have many defects in some similar structures when used in practice. For example, the packaging bag design is relatively tight, especially for tightly sealed or thick packaging bags, which makes it inconvenient to cut the packaging bags effectively. At the same time, on the packaging bag production line, if the packaging bags cannot be transported away for cutting in time, they will accumulate in the bag making area, causing the equipment to have to stop working, which will significantly reduce the production efficiency of the entire production line.

[0004] To address the aforementioned problems, the inventors have proposed a cutting device for packaging bag production. Utility Model Content

[0005] To address the problems of inconvenience in cutting and transporting packaging bags, the purpose of this utility model is to provide a cutting device for packaging bag production.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a cutting device for packaging bag production, including a table, conveying devices fixedly connected to both sides of the table, a shearing device fixedly connected to the top surface of the table, the shearing device including a bracket, a cylinder fixedly sleeved on the top surface of the bracket, a pressure plate fixedly connected to the output end of the cylinder, sliders fixedly connected to both ends of the pressure plate, grooves for cooperating with the sliders being opened on both sides of the inner wall of the bracket, and a cutting tool fixedly connected to the bottom surface of the pressure plate.

[0007] As a preferred technical solution of this application, the conveying device includes symmetrically distributed fixed frames. One side of the fixed frame is fixedly connected to the table surface. Two rotating shafts are rotatably connected between the inner walls of the two sides of the fixed frame. A motor is fixedly connected to one side of the fixed frame. The output end of the motor extends into the fixed frame and is fixedly connected to the rotating shaft. A sprocket is fixedly sleeved on the outer surface of the upper rotating shaft. A chain is meshed between the sprockets. A gear is fixedly sleeved on the outer surface of the rotating shaft away from the sprocket. A roller is fixedly sleeved on the outer surface of the rotating shaft.

[0008] Using the above technical solution, the packaging bag is passed between two rollers. The motor is started, and its output end drives the fixed shaft to rotate. When the shaft rotates, it drives the sprocket to rotate as well. The sprockets are connected by a chain. When one sprocket rotates, it drives the other sprocket to rotate through the chain, thereby causing the upper shafts on both sides to rotate synchronously. When the upper shaft rotates, it drives the lower shaft that it is meshed with to rotate in the opposite direction. The rotation of the shaft drives the roller to rotate. The two rollers rotate relative to each other, transporting the packaging bag to the table, which can effectively transport the packaging bag.

[0009] As a preferred technical solution of this application, a hollow tube is symmetrically connected to one side of the top surface of the bracket, and a guide rod is slidably connected to the inner wall of the hollow tube, and the bottom end of the guide rod is fixedly connected to the pressure plate.

[0010] With the above technical solution, when the pressure plate moves downward, the guide rod slides inside the hollow tube, which further guides the movement of the pressure plate and ensures the accuracy of cutting.

[0011] As a preferred technical solution of this application, connecting plates are symmetrically fixedly connected to both sides of the pressure plate, a hollow sleeve is fixedly connected to the end of the connecting plate, a connecting tube is slidably connected to the inner wall of the hollow sleeve, a limit plate is fixedly connected to the top of the connecting tube, a fixing block is fixedly connected to the bottom of the connecting tube, and one end of the fixing block is fixedly connected to the table surface.

[0012] Through the above technical solution, when the pressure plate moves downward, the connecting pipe slides inside the hollow sleeve, which also plays a certain guiding and stabilizing role.

[0013] As a preferred technical solution of this application, both the slider and the groove are T-shaped.

[0014] The above technical solutions allow the T-shaped sliders and grooves to work together more effectively.

[0015] As a preferred technical solution of this application, the top surface of the table is provided with a tool groove for use with a cutting tool.

[0016] Through the above technical solution, the groove provides a space for the cutting tool during cutting, enabling the cutting to proceed smoothly.

[0017] As a preferred technical solution of this application, the outer surfaces of the gears on the same side are meshed and connected to each other.

[0018] Through the above technical solution, the gears mesh with each other, and the two rollers rotate relative to each other.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model can guide the movement of the pressure plate by having the guide rod slide inside the hollow tube when the pressure plate moves downward. When the pressure plate moves downward, the connecting tube slides inside the hollow sleeve. The knife groove provides a space for the knife to be accommodated when the knife is cutting, so that the cutting can be carried out smoothly, thereby achieving the purpose of effectively cutting the packaging bag.

[0021] 2. This utility model can drive one sprocket to rotate through a chain, thereby causing the upper rotating shafts on both sides to rotate synchronously. When the upper rotating shaft rotates, it will drive the lower rotating shaft meshed with it to rotate in the opposite direction. When the rotating shafts rotate, they will drive the rollers to rotate. The two rollers rotate relative to each other, transporting the packaging bag to the table, thus achieving the purpose of effectively transporting the packaging bag. Attached Figure Description

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.

[0029] Example: Figure 1-4 As shown, this utility model provides a cutting device for packaging bag production, including a table 1, conveying devices 2 fixedly connected to both sides of the table 1, and a cutting device 3 fixedly connected to the top surface of the table 1. The cutting device 3 includes a bracket 301, a cylinder 304 fixedly sleeved on the top surface of the bracket 301, a pressure plate 305 fixedly connected to the output end of the cylinder 304, and sliders 311 fixedly connected to both ends of the pressure plate 305. Slide grooves 312 for use with sliders 311 are opened on both sides of the inner wall of the bracket 301. Both sliders 311 and slide grooves 312 are T-shaped. A cutter 313 is fixedly connected to the bottom surface of the pressure plate 305, and a cutter groove 314 for use with the cutter 313 is opened on the top surface of the table 1.

[0030] When the cylinder 304 is activated, its output end pushes the pressure plate 305 downward. The sliders 311 at both ends of the pressure plate 305 slide in the grooves 312 on the inner walls of both sides of the bracket 301, which serves to guide and stabilize the pressure plate, ensuring that the pressure plate 305 moves vertically downward. The cutter 313, which is fixedly connected to the bottom surface of the pressure plate 305, moves downward together with the pressure plate 305. The cutter groove 314 provides a space for the cutter 313 to be accommodated when it is cutting, so that the cutting can be carried out smoothly and the packaging bag can be effectively cut.

[0031] A hollow tube 302 is symmetrically connected to one side of the top surface of the bracket 301. A guide rod 303 is slidably connected to the inner wall of the hollow tube 302. The bottom end of the guide rod 303 is fixedly connected to the pressure plate 305. A connecting plate 306 is symmetrically fixedly connected to both sides of the pressure plate 305. A hollow sleeve 307 is fixedly connected to the end of the connecting plate 306. A connecting tube 308 is slidably connected to the inner wall of the hollow sleeve 307. A limit plate 309 is fixedly connected to the top end of the connecting tube 308. A fixing block 310 is fixedly connected to the bottom end of the connecting tube 308. One end of the fixing block 310 is fixedly connected to the table surface 1.

[0032] When the pressure plate 305 moves downward, the guide rod 303 slides inside the hollow tube 302, further guiding the movement of the pressure plate 305 and ensuring the accuracy of the cutting. When the pressure plate 305 moves downward, the connecting tube 308 slides inside the hollow sleeve 307, which also plays a certain guiding and stabilizing role. The knife groove 314 provides a space for the knife 313 to be accommodated when the knife 313 is cutting, so that the cutting can be carried out smoothly.

[0033] The conveying device 2 includes symmetrically distributed fixed frames 21. One side of the fixed frame 21 is fixedly connected to the table surface 1. Two rotating shafts 22 are rotatably connected between the inner walls of the two sides of the fixed frame 21. A motor 23 is fixedly connected to one side of one of the fixed frames 21. The output end of the motor 23 extends into the fixed frame 21 and is fixedly connected to the rotating shaft 22. A sprocket 24 is fixedly sleeved on the outer surface of the upper rotating shaft 22. A chain 25 is meshed between the sprockets 24. A gear 26 is fixedly sleeved on the outer surface of the rotating shaft 22 away from the sprocket 24. The outer surfaces of the gears 26 on the same side are meshed with each other. A roller 27 is fixedly sleeved on the outer surface of the rotating shaft 22.

[0034] The working principle of the cutting device for packaging bag production in this embodiment is as follows: The packaging bag is passed between two rollers 27. The motor 23 is started, and its output end drives the rotating shaft 22 fixedly connected to it to rotate. When the rotating shaft 22 rotates, it drives the sprocket 24 to rotate together. The sprockets 24 are connected by a chain 25. When one sprocket 24 rotates, it drives the other sprocket 24 to rotate through the chain 25, thereby making the upper rotating shafts 22 on both sides rotate synchronously. When the upper rotating shaft rotates, it drives the lower rotating shaft 22 that it is engaged with to rotate in the opposite direction. When the rotating shaft 22 rotates, it drives the rollers 27 to rotate. The two rollers 27 rotate relative to each other, transporting the packaging bag to the table 1, thereby achieving the purpose of effectively transporting the packaging bag.

[0035] When the packaging bag material is conveyed onto the table 1, the cylinder 304 is activated, and its output end pushes the pressure plate 305 downward. The sliders 311 at both ends of the pressure plate 305 slide in the grooves 312 on the inner walls of the bracket 301, which guides and stabilizes the pressure plate, ensuring that the pressure plate 305 moves vertically downward. The cutter 313, which is fixedly connected to the bottom of the pressure plate 305, moves downward with the pressure plate 305. When the pressure plate 305 moves downward, the guide rod 303 slides in the hollow tube 302, which further guides the movement of the pressure plate 305 and ensures the accuracy of the cutting. When the pressure plate 305 moves downward, the connecting tube 308 slides in the hollow sleeve 307, which also plays a certain guiding and stabilizing role. The cutter groove 314 provides a space for the cutter 313 to be accommodated when the cutter 313 is cutting, so that the cutting can be carried out smoothly, thereby achieving the purpose of effectively cutting the packaging bag.
