Description

Technical Field

[0001] This utility model relates to the field of anti-slip embossed structures for packaging bags, specifically an anti-slip embossed structure for a heavy-duty film packaging bag. Background Technology

[0002] Heavy-duty film packaging bags are industrial packaging bags with a thickness much greater than ordinary plastic packaging bags. It does not refer to a single type of plastic bag, but rather a product category widely used for packaging bulk materials. Its core characteristics are high strength and high durability. The anti-slip embossed structure refers to the regular, uneven textures or patterns pressed into the surface of the plastic film during the production process of heavy-duty film packaging bags, which increases friction and prevents slippage, thus solving the problem of slippage and stability of ton bags during stacking and transportation.

[0003] Although the anti-slip embossed structure of existing heavy-duty film packaging bags has made progress, it still has many shortcomings in practical applications. The traditional anti-slip embossed structure of heavy-duty film packaging bags uses a special embossing plate to press regular, uneven textures or patterns on the surface of heated plastic film. However, the heavy-duty film packaging bags will be subjected to a certain tension during movement. If the pressing is uneven, it will easily cause the heavy-duty film packaging bags to deform, reducing product quality. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the traditional anti-slip embossed structure of heavy-duty film packaging bags uses a special embossing plate to press regular, uneven textures or patterns onto the surface of heated plastic film. However, heavy-duty film packaging bags are subjected to a certain tension during movement, and uneven pressing can easily lead to deformation of the heavy-duty film packaging bags, reducing product quality and other problems. This utility model proposes an anti-slip embossed structure for heavy-duty film packaging bags.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an anti-slip embossed structure for heavy film packaging bags, including a base plate, a shell fixedly connected to one side of the base plate, and a squeezing mechanism provided in the inner cavity of the shell; The extrusion mechanism includes a first rotating roller, the surface of which is rotatably connected to the inner cavity of the outer shell. A second rotating roller, a third rotating roller, and a fourth rotating roller are rotatably connected to the inner cavity of the outer shell. Embossing plates are drivenly connected to the surfaces of the fourth rotating roller, the third rotating roller, the second rotating roller, and the first rotating roller. A fixing rod is fixedly connected to the inner cavity of the outer shell, and a pressure plate is fixedly connected to the surface of the fixing rod. One side of the pressure plate is attached to one side of the embossing plate.

[0006] Preferably, a through groove is provided on one side of the pressure plate, and a heating device is provided in the inner cavity of the through groove.

[0007] Preferably, a motor is fixedly connected to the inner cavity of the outer shell, and the output end of the motor is fixedly connected to one end of the first rotating roller.

[0008] Preferably, a rotating rod is rotatably connected to one side of the outer casing, and there are multiple rotating rods.

[0009] Preferably, a first gear is fixedly connected to the surface of the second rotating roller, and a second gear is fixedly connected to the surface of the rotating rod, wherein the teeth of the second gear mesh with the teeth of the first gear.

[0010] Preferably, the inner cavity of the outer shell is rotatably connected to a fifth rotating roller, and the surface of the fifth rotating roller is connected to the surface of the rotating rod by a transmission belt.

[0011] Preferably, a discharge port is provided on one side of the outer shell, and a cooling device is provided inside the discharge port.

[0012] The advantages of this utility model are: This invention employs an extrusion mechanism. A first rotating roller actively rotates, driving a second, third, and fourth rotating roller to rotate via an embossing plate. Simultaneously, the embossing plate rotates under the constraint of these rollers. The embossing plate has a regular, uneven texture or pattern on its surface. The rotating embossing plate extrudes the heavy-duty film packaging bag, imprinting the pattern. When the heavy-duty film packaging bag moves between the second and third rotating rollers, the heated bag may bulge due to uneven pressure. Because the pressure plate is limited by a fixing rod, its fixed shape allows it to apply pressure to the embossing plate, preventing bulging. This solves the problem of traditional anti-slip embossing structures for heavy-duty film packaging bags, which use specialized embossing plates to press regular, uneven textures or patterns onto the heated plastic film surface. However, the heavy-duty film packaging bag experiences tension during movement, and uneven pressure can easily lead to deformation and reduced product quality. Attached Figure Description

[0016] 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.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses an anti-slip embossed structure for a heavy-duty film packaging bag. (Refer to...) Figures 1 to 4 An anti-slip embossed structure for a heavy film packaging bag includes a base plate 1, a shell 2 fixedly connected to one side of the base plate 1, and an extrusion mechanism 3 provided in the inner cavity of the shell 2. The extrusion mechanism 3 includes a first rotating roller 301, the surface of which is rotatably connected to the inner cavity of the outer shell 2. A second rotating roller 302, a third rotating roller 303, and a fourth rotating roller 304 are rotatably connected to the inner cavity of the outer shell 2. An embossing plate 305 is drively connected to the surfaces of the fourth rotating roller 304, the third rotating roller 303, the second rotating roller 302, and the first rotating roller 301. A fixing rod 306 is fixedly connected to the inner cavity of the outer shell 2, and a pressure plate 307 is fixedly connected to the surface of the fixing rod 306. One side of the pressure plate 307 is attached to one side of the embossing plate 305. By setting the extrusion mechanism 3, the first rotating roller 301 rotates actively, and the embossing plate 305... 05 drives the second rotating roller 302, the third rotating roller 303, and the fourth rotating roller 304 to rotate, while simultaneously allowing the embossing plate 305 to rotate under the limitation of the first rotating roller 301, the second rotating roller 302, the third rotating roller 303, and the fourth rotating roller 304. The surface of the embossing plate 305 has regular, uneven textures or patterns. The rotating embossing plate 305 squeezes the heavy film packaging bag to imprint the pattern. When the heavy film packaging bag moves between the second rotating roller 302 and the third rotating roller 303, the heated heavy film packaging bag may bulge due to uneven pressure during the movement. Since the pressure plate 307 is limited by the fixing rod 306, the fixed-shape pressure plate 307 can apply pressure to the embossing plate 305 it is attached to, preventing the heavy film packaging bag from bulging.

[0018] Reference Figure 4 A through groove 4 is provided on one side of the pressure plate 307. A heating device 5 is provided in the inner cavity of the through groove 4. By providing the heating device 5, the heating device 5 can continuously heat the heavy film packaging bag during the pressing process, making the heavy film packaging bag more easily deformed and preventing the heavy film packaging bag from being prematurely shaped. The heating device 5 is an existing structure, model SJ, and its structural components include a gearbox, a heating coil, a separable screw, and a barrel.

[0019] Reference Figure 5 A motor 6 is fixedly connected to the inner cavity of the outer shell 2. The output end of the motor 6 is fixedly connected to one end of the first rotating roller 301. By setting the motor 6, the motor 6 works and controls the first rotating roller 301 fixedly connected to its output end to rotate, thereby providing power to the extrusion mechanism 3 so that the embossing plate 305 can rotate.

[0020] Reference Figure 5 A rotating rod 7 is rotatably connected to one side of the outer casing 2. There are multiple rotating rods 7. By setting the rotating rods 7, the rotating rods 7 can serve as a support structure for the second gear 9 and the transmission belt 11, so that the second gear 9 and the transmission belt 11 can operate stably.

[0021] Reference Figure 5A first gear 8 is fixedly connected to the surface of the second rotating roller 302, and a second gear 9 is fixedly connected to the surface of the rotating rod 7. The teeth of the second gear 9 mesh with the teeth of the first gear 8. By setting the second gear 9 and the first gear 8, the rotation of the second rotating roller 302 drives the first gear 8 fixedly connected to its surface to rotate. Since the teeth of the second gear 9 mesh with the teeth of the first gear 8, the first gear 8 drives the second gear 9 and the rotating rod 7 connected to the second gear 9 to rotate and change the direction of rotation.

[0022] Reference Figure 5 The inner cavity of the outer shell 2 is rotatably connected to a fifth rotating roller 10. The surface of the fifth rotating roller 10 is connected to the surface of the rotating rod 7 by a transmission belt 11. By setting the transmission belt 11, since the surface of the fifth rotating roller 10 is connected to the surface of the rotating rod 7 by the transmission belt 11, the rotating rod 7 drives the fifth rotating roller 10 to rotate, so that the fifth rotating roller 10 can drive the corresponding extrusion mechanism 3 to run, so that the embossing plates 305 of the upper and lower extrusion mechanisms 3 can drive the heavy film packaging bag to move and perform double-sided embossing on the heavy film packaging bag.

[0023] Reference Figure 4 The outer shell 2 has a discharge port 12 on one side. The inner cavity of the discharge port 12 is equipped with a cooling device 13. By setting the cooling device 13, the ambient temperature can be reduced so that the heavy film packaging bag that has been printed can be quickly shaped. The cooling device 13 is an existing structure, model FK. Its structural components include a wind ring body, an air outlet lip, an adjusting bolt, and a heat exchanger.

[0024] Working principle: Motor 6 operates, controlling the rotation of the first rotating roller 301 fixedly connected to its output end. The first rotating roller 301 drives the second rotating roller 302, the third rotating roller 303, and the fourth rotating roller 304 to rotate via the embossing plate 305. Simultaneously, the embossing plate 305 rotates under the limiting position of the first rotating roller 301, the second rotating roller 302, the third rotating roller 303, and the fourth rotating roller 304. The surface of the embossing plate 305 has regular, uneven textures or patterns. The rotating embossing plate 305 squeezes the heavy film packaging bag to imprint the pattern. When the heavy film packaging bag moves between the second rotating roller 302 and the third rotating roller 303, the heated heavy film packaging bag may bulge due to uneven pressure during movement. Because the pressure plate 307 is fixed by the rod 306... The fixed-shape pressure plate 307 can apply pressure to the embossed plate 305 it is attached to, preventing the heavy film packaging bag from bulging. At the same time, the rotating second rotating roller 302 drives the first gear 8 fixedly connected to its surface to rotate. Since the teeth of the second gear 9 mesh with the teeth of the first gear 8, the first gear 8 drives the second gear 9 and the rotating rod 7 connected to the second gear 9 to rotate and change the direction of rotation. Since the surface of the fifth rotating roller 10 is connected to the surface of the rotating rod 7 by a transmission belt 11, the rotating rod 7 drives the fifth rotating roller 10 to rotate, so that the fifth rotating roller 10 can drive the corresponding extrusion mechanism 3 to run, so that the embossed plates 305 of the upper and lower extrusion mechanisms 3 can move the heavy film packaging bag and perform double-sided embossing on the heavy film packaging bag.
