Description

Technical Field

[0001] This utility model relates to the field of plastic bag production technology, and in particular to a bag-supporting mechanism for a bag-making machine. Background Technology

[0002] To facilitate the bag making process, bag making machines are essential. One of the processes in the operation of a bag making machine is to support the plastic bag with tension, and then use an external punching mechanism to punch holes in the long strip of bag in sections. Later, by tearing the long strip of bag through the punched holes, multiple bag components can be obtained.

[0003] Traditional bag-supporting mechanisms have the following drawbacks: 1. Long, strip-shaped bags are difficult to tighten during transport due to slippage of the conveyor rollers, resulting in poor flatness during bag support and hindering the punching process. Therefore, we propose a new bag-supporting mechanism for bag-making machines. Summary of the Invention

[0004] The main purpose of this utility model is to provide a bag-supporting mechanism for a bag-making machine, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A bag-supporting mechanism for a bag-making machine includes a base, a fixed platform, supporting legs, a lower L-shaped plate, a first guide roller, a first servo electric cylinder, a first rotating roller, a second rotating roller, and a third rotating roller. The lower L-shaped plate is mounted on the top end of the base via the supporting legs. The power output end of the first servo electric cylinder is connected to a connecting plate. An upper L-shaped plate is bolted to the bottom of the connecting plate. Guide grooves are formed through one end of both the upper and lower L-shaped plates, and guide blocks are fitted inside the guide grooves. First vertical plates are mounted on both sides of the guide blocks. A first rotating roller is mounted on one side of the bottom end of the first vertical plate via a rotating shaft. Anti-slip textures are provided around the outer periphery of the first rotating roller. Mounting frames are provided at points away from each other on one end of the upper and lower L-shaped plates. A second servo electric cylinder is mounted on the bottom of the mounting frame via a fixed seat. A first extension plate is connected to one side of the first vertical plate, and the power output end of the second servo electric cylinder is welded to the first extension plate.

[0007] Furthermore, a third vertical plate is provided at one end of the upper L-shaped plate and the lower L-shaped plate that are close to each other, and a second vertical plate is provided at the center of the upper L-shaped plate and the lower L-shaped plate that are close to each other. A second rotating roller is provided between the second vertical plates through a rotating shaft, and the second rotating roller facilitates the guidance of the conveying of the long strip plastic bag.

[0008] Furthermore, a third rotating roller is provided between the third vertical plates via a rotating shaft, and a second extension plate is welded to one side of the third vertical plate. A servo motor is provided near the second extension plate via a fixed seat, and the power output end of the servo motor is connected to the rotating shaft of the third rotating roller.

[0009] Furthermore, a fixed platform is provided at the top of the base away from the supporting leg. Guide sleeves are provided on both sides of the top of the fixed platform through fixed grooves. A sleeve rod is sleeved inside the guide sleeve. A U-shaped plate is connected to the top of the sleeve rod. A first guide roller is provided between the top ends of the U-shaped plates through a rotating shaft. A columnar spring is connected to the outside of the sleeve rod. The bottom of the columnar spring is welded to the top of the guide sleeve. Through the limiting and guiding effect of the guide sleeve on the sleeve rod, the stability of the U-shaped plate during lifting and lowering can be effectively improved. The columnar spring can apply an upward tension force to the U-shaped plate, so that the long strip bag can be tightened to a certain extent when passing over the first guide roller.

[0010] Furthermore, a vertical plate is welded to one end of the base near both sides, a top plate is connected to the top of the vertical plate, and a first servo electric cylinder is bolted to the bottom of the top plate near the center.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present invention relates to a bag-supporting mechanism for a bag-making machine. Because the first rotating roller has a good anti-slip effect and can apply a horizontal force to the bag body when the first rotating roller is close to the bag, the bag body in the transmission can be tightened better, so that the bag-supporting mechanism has a better flatness effect when supporting the bag, which is conducive to the subsequent punching work.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-3 As shown, a bag-making machine's bag-supporting mechanism includes a base 1, a fixed platform 2, a support leg 23, a lower L-shaped plate 24, a first guide roller 7, a first servo electric cylinder 10, a first rotating roller 17, a second rotating roller 26, and a third rotating roller 20. The lower L-shaped plate 24 is mounted on one end of the base 1 via the support leg 23. The power output end of the first servo electric cylinder 10 is connected to a connecting plate 11. An upper L-shaped plate 12 is bolted to the bottom of the connecting plate 11. Guide grooves 15 are provided through one side of both the upper L-shaped plate 12 and the lower L-shaped plate 24. The inner sleeve of the 15 is provided with a guide block 28. A first vertical plate 16 is provided on both sides of the guide block 28. A first rotating roller 17 is provided on one side of the bottom end of the first vertical plate 16 through a rotating shaft. The outer periphery of the first rotating roller 17 is provided with anti-slip texture 27. A mounting bracket 13 is provided at one end of the upper L-shaped plate 12 and the lower L-shaped plate 24 at a distance from each other. A second servo electric cylinder 14 is provided at the bottom of the mounting bracket 13 through a fixed seat. A first extension plate 18 is connected to one side of the first vertical plate 16. The power output end of the second servo electric cylinder 14 is welded to the first extension plate 18.

[0019] The upper L-shaped plate 12 and the lower L-shaped plate 24 are each provided with a third vertical plate 19 at one end near each other, and a second vertical plate 25 is provided at the center of the upper L-shaped plate 12 and the lower L-shaped plate 24 near each other. A second rotating roller 26 is provided between the second vertical plates 25 through a rotating shaft.

[0020] In this embodiment, as shown... Figure 2-3 As shown, the second rotating roller 26 facilitates the guidance of the conveying of the long strip plastic bag.

[0021] A third rotating roller 20 is provided between the third vertical plates 19 via a rotating shaft. A second extension plate 21 is welded to one side of the third vertical plate 19. A servo motor 22 is provided near the second extension plate 21 via a fixed seat. The power output end of the servo motor 22 is connected to the rotating shaft of the third rotating roller 20.

[0022] In this embodiment, as shown... Figure 1 As shown, the servo motor 22 can easily drive the third rotating roller 20 to rotate during operation.

[0023] The base 1 has a fixed platform 2 at the top of the end away from the support leg 23. The fixed platform 2 has guide sleeves 3 on both sides of the top through fixed grooves. The guide sleeves 3 are fitted with sleeve rods 4. The top of the sleeve rods 4 is connected to a U-shaped plate 6. The top of the U-shaped plates 6 is connected to a first guide roller 7 through a rotating shaft. The sleeve rods 4 are connected to a columnar spring 5 on the outside. The bottom of the columnar spring 5 is welded to the top of the guide sleeves 3.

[0024] In this embodiment, as shown... Figure 1-3 As shown, the guide sleeve 3 limits and guides the sleeve rod 4, which can effectively improve the stability of the U-shaped plate 6 during lifting. The column spring 5 can apply an upward tension force to the U-shaped plate 6, so that the long strip bag can be tightened to a certain extent when it passes above the first guide roller 7.

[0025] The base 1 has a vertical plate 8 welded to one end near both sides, and a top plate 9 is connected to the top of the vertical plate 8. The first servo electric cylinder 10 is bolted to the bottom of the top plate 9 near the center.

[0026] In this embodiment, as shown... Figure 1-3 As shown, the first servo electric cylinder 10 is easily installed at the bottom of the top plate 9 by bolts.

[0027] It should be noted that this utility model is a bag-supporting mechanism for a bag-making machine. During operation, the first servo electric cylinder 10 conveniently drives the connecting plate 11 and the upper L-shaped plate 12 to press down. Through the limiting and guiding effect of the guide sleeve 3 on the sleeve rod 4, the stability of the U-shaped plate 6 during lifting and lowering can be effectively improved. The columnar spring 5 can apply an upward tension force to the U-shaped plate 6, so that the long strip bag can be tightened to a certain extent when passing over the first guide roller 7. After passing over the first guide roller 7, the bag passes between two sets of first rotating rollers 17, second rotating rollers 26 and third rotating rollers 20. The distance between the two sets of first rotating rollers 17, second rotating rollers 26 and third rotating rollers 20 can be conveniently adjusted by the first servo electric cylinder 10 to facilitate the passage of bags of different thicknesses. However, when the servo motor 22 is working, it drives the third rotating roller 20 to rotate, thereby providing power for the conveying of the bag. When the second servo electric cylinder 14 is working, it can push the first extension plate 18, thereby causing the guide block 28 to move along the direction of the guide groove 15, which in turn makes it easier for the first rotating roller 17 to approach in an inclined direction. The anti-slip texture 27 on the outer periphery of the first rotating roller 17 can increase the anti-slip effect between the first rotating roller 17 and the bag when in contact. Since the first rotating roller 17 has a good anti-slip effect, and the first rotating roller 17 can apply a horizontal force to the bag when approaching, the bag in the transmission can be tightened better, making the flatness of the bag-making mechanism better when supporting the bag, which is beneficial to the subsequent punching work.
