Description

Technical Field

[0001] This utility model relates to the field of embossing technology, specifically to a composite embossing device for moisture-proof and freeze-proof bags without an inner membrane. Background Technology

[0002] In the packaging industry, the function of the moisture-proof and freeze-proof composite embossing device for inner film-free bags is to form special textures and structures on the surface of the bag through composite embossing process, thereby simultaneously improving moisture-proof and freeze-proof performance.

[0003] The device consists of a composite embossing module, a temperature control system, a moisture-proof coating spraying unit, a tension adjustment mechanism, and a PLC control system. The inner membrane-free bag substrate is conveyed by a conveyor belt, first uniformly coated with a waterproof coating by the moisture-proof coating spraying unit, and then enters the temperature-controlled embossing module. The heated rollers press out a diamond-shaped composite texture on the surface of the bag, and finally the processing is completed after cooling and shaping.

[0004] However, the above-mentioned equipment has obvious shortcomings in use. The pressure of the traditional embossing device is fixed. For bags of different thicknesses, too much pressure will cause the bag to break, while too little pressure will result in a shallow pattern. The pressure valve needs to be manually adjusted, and the efficiency is extremely low when producing multiple specifications. In view of this, we have proposed a composite embossing device for bags without inner film that is moisture-proof and freeze-proof. Utility Model Content

[0005] The purpose of this invention is to provide a moisture-proof and freeze-proof composite embossing device for bags without inner membranes, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A moisture-proof, freeze-proof, and crack-resistant composite embossing device for a membrane-free bag includes a hydraulic unwinding frame, an electric winding frame externally mounted on the hydraulic unwinding frame, a connecting frame fixedly installed between the hydraulic unwinding frame and the electric winding frame, and an embossing assembly mounted on the connecting frame. The embossing assembly includes: A bottom flattening roller is rotatably mounted on the connecting frame. The connecting frame has an installation groove. One end of a spring rod is fixedly mounted on the connecting frame. A hinge block is fixedly mounted on the other end of the spring rod. A metal roller is rotatably mounted on the hinge block. An installation frame is fixedly mounted on the connecting frame. Hydraulic device No. 1 is fixedly installed on the mounting frame. A slide is fixedly installed on the piston end of hydraulic device No. 1. An embossing roller is rotatably installed on the slide. A power motor is fixedly installed on the slide. A support frame is fixedly installed on the connecting frame. Hydraulic device No. 2 is fixedly installed on the support frame. A sliding frame is fixedly installed on the piston end of the second hydraulic device. A heating roller is rotatably installed on the sliding frame. A vertical frame is fixedly installed on the connecting frame. A top flattening roller is rotatably installed on the vertical frame. Anti-slip strips are fixedly installed on the bottom flattening roller and the top flattening roller.

[0007] In a further embodiment, multiple sets of the connecting frame, mounting groove, spring rod, hinge block, metal roller, first hydraulic device, second hydraulic device, vertical frame, and anti-slip strip are provided.

[0008] In a further embodiment, the embossing roller and the heating roller are respectively positioned above a single set of metal rollers, the bottom flattening roller is positioned below the unwinding roller of the hydraulic unwinding frame, and the top flattening roller is positioned above the winding roller of the electric winding frame.

[0009] In a further embodiment, the spring rod is disposed inside the mounting groove, the hinge block slides inside the mounting groove, and the output end of the power motor is connected to the embossing roller.

[0010] In a further embodiment, the connecting frame is provided with an auxiliary component, which includes a support roller rotatably mounted on the connecting frame. A servo motor is fixedly mounted on the connecting frame, and a bottom electrostatic roller is fixedly mounted on the output end of the servo motor. An mounting block is fixedly mounted on the connecting frame, and a top electrostatic roller is rotatably mounted on the mounting block. A drive gear is fixedly mounted on the end of the bottom electrostatic roller away from the servo motor, and a driven gear is fixedly mounted on the top electrostatic roller.

[0011] In a further embodiment, multiple sets of support rollers are provided, with the multiple sets of support rollers positioned on both sides of the top electrostatic roller.

[0012] In a further embodiment, the driving gear meshes with the driven gear, and the top electrostatic roller is positioned directly above the bottom electrostatic roller.

[0013] Compared with the prior art, this utility model provides a moisture-proof and freeze-proof composite embossing device for bags without inner membranes, which has the following beneficial effects: 1. This embossing device for moisture-proof and freeze-proof composite embossing of inner-membrane-free bags is designed to meet the harsh environmental requirements of inner-membrane-free bags. It incorporates an embossing component that, in conjunction with a hydraulic unwinding frame, feeds material to an electric winding frame. This activates a second hydraulic device, which drives a sliding frame to lower a heating roller. This roller, working in conjunction with a metal roller, pre-heats the bag, softening the material and laying the foundation for subsequent embossing. Subsequently, a first hydraulic device drives the sliding frame to press down the embossing roller, pressing a uniform pattern onto the softened bag surface. The heated material is easier to shape, effectively enhancing the bag's moisture-proof and freeze-proof capabilities. Simultaneously, bottom and top leveling rollers work together to maintain a flat conveyor throughout the process, while a spring rod pushes a metal roller to provide support, preventing bag deformation during embossing.

[0014] 2. This membraneless bag moisture-proof and freeze-proof composite embossing device, in order to further improve the moisture-proof and freeze-proof effect of the membraneless bag, is equipped with an auxiliary component. This component works with a servo motor to drive the bottom electrostatic roller to rotate. Through the meshing of the drive gear and the driven gear, the top electrostatic roller rotates synchronously in the opposite direction. When the bag is released from the hydraulic unwinding frame, it first passes between the bottom and top electrostatic rollers. The double rollers quickly eliminate the static electricity on the surface of the bag, avoiding the static attraction of workshop dust, fibers and other impurities, ensuring that the embossed surface of the bag is clean and free of impurities. At the same time, multiple sets of support rollers on both sides of the top electrostatic roller provide stable support from below the bag, ensuring that the bag is transported to the subsequent embossing component in a flat state.

It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0019] Please see Figures 1-6 This utility model provides a technical solution: A moisture-proof and freeze-proof composite embossing device for a bag without an inner lining includes a hydraulic unwinding frame 1, an electric winding frame 2 externally mounted on the hydraulic unwinding frame 1, and a connecting frame 3 fixedly installed between the hydraulic unwinding frame 1 and the electric winding frame 2.

[0020] In one embodiment of this utility model, a texturing component 4 is provided on the connecting frame 3. The texturing component 4 includes a bottom flattening roller 41, which is rotatably mounted on the connecting frame 3. The connecting frame 3 has an installation groove 42. One end of a spring rod 43 is fixedly mounted on the connecting frame 3, and a hinge block 44 is fixedly mounted on the other end of the spring rod 43. A metal roller 45 is rotatably mounted on the hinge block 44. A mounting frame 46 is fixedly mounted on the connecting frame 3. A first hydraulic device 47 is fixedly mounted on the mounting frame 46. A slide 48 is fixedly mounted on the piston end of the first hydraulic device 47. A texturing roller 49 is rotatably mounted on the slide 48. A power motor 410 is fixedly mounted on the slide 48. A support frame 411 is fixedly mounted on the connecting frame 3. A second hydraulic device 412 is fixedly mounted on the support frame 411. A sliding frame 413 is fixedly mounted on the piston end of the second hydraulic device 412. A heating roller 414 is rotatably mounted on the sliding frame 413. A vertical frame 415 is fixedly mounted on the connecting frame 3. A top flattening roller 416 is rotatably mounted on the vertical frame 415. Anti-slip strips 417 are fixedly mounted on the bottom flattening roller 41 and the top flattening roller 416. Multiple sets of connecting frame 3, mounting groove 42, spring rod 43, hinge block 44, metal roller 45, first hydraulic device 47, second hydraulic device 412, vertical frame 415 and anti-slip strips 417 are provided. The embossing roller 49 and the heating roller 414 are respectively set above a single set of metal rollers 45. The bottom flattening roller 41 is set below the unwinding roller of the hydraulic unwinding frame 1. The top flattening roller 416 is set above the winding roller of the electric winding frame 2. The spring rod 43 is set inside the mounting groove 42. The hinge block 44 slides inside the mounting groove 42. The output end of the power motor 410 is connected to the embossing roller 49.

[0021] In this embodiment, during production, the hydraulic unwinding frame 1 releases the raw material for the inner film-free bag. The raw material first passes through the bottom flattening roller 41 on the connecting frame 3. The anti-slip strip 417 on the bottom flattening roller 41 increases the friction with the bag body to prevent the bag from slipping. At the same time, it initially flattens the bag body to prevent wrinkles from entering subsequent processes. The bag body continues to be conveyed to the heating area. The second hydraulic device 412 on the support frame 411 is activated. Its piston end pushes the sliding frame 413 down, driving the heating roller 414 to move closer to the lower metal roller 45 until the heating roller 414 and the metal roller 45 jointly clamp the bag body. The heating roller 414 is energized to generate heat, performing a preheating treatment on the bag body to soften the bag material. At the same time, the metal roller 45, under the pushing force of the spring rod 43, moves through the hinge... The connecting block 44 slides adaptively along the mounting groove 42, closely fitting the surface of the bag, providing stable support for the heating roller 414, ensuring uniform heating of the bag, and avoiding local overheating that could damage the material. After heating, the bag is conveyed to the embossing area. The first hydraulic device 47 on the mounting frame 46 is activated, and its piston end pushes the slide 48 down, causing the embossing roller 49 and the lower metal roller 45 to clamp the bag. At the same time, the power motor 410 on the slide 48 is activated, driving the embossing roller 49 to rotate and pressing a uniform pattern on the softened bag surface. After the pattern is shaped, the structural density of the bag is increased, effectively enhancing its moisture resistance and freeze-cracking resistance. Finally, the embossed bag passes through the top flattening roller 416 on the vertical frame 415 and is wound up at a uniform speed by the electric winding frame 2, forming a continuous production process.

[0022] In one embodiment of this utility model, an auxiliary component 5 is provided on the connecting frame 3. The auxiliary component 5 includes a support roller 51, which is rotatably mounted on the connecting frame 3. A servo motor 52 is fixedly mounted on the connecting frame 3. A bottom electrostatic roller 57 is fixedly mounted on the output end of the servo motor 52. An mounting block 53 is fixedly mounted on the connecting frame 3. A top electrostatic roller 54 is rotatably mounted on the mounting block 53. A drive gear 55 is fixedly mounted on the end of the bottom electrostatic roller 57 away from the servo motor 52. A driven gear 56 is fixedly mounted on the top electrostatic roller 54. Multiple sets of support rollers 51 are provided, and multiple sets of support rollers 51 are provided on both sides of the top electrostatic roller 54. The drive gear 55 meshes with the driven gear 56. The top electrostatic roller 54 is located directly above the bottom electrostatic roller 57.

[0023] In this embodiment, after the bag is released from the hydraulic unwinding frame 1, the servo motor 52 on the connecting frame 3 is started. Its output end drives the bottom electrostatic roller 57 to rotate. The bottom electrostatic roller 57 meshes with the driven gear 56 of the top electrostatic roller 54 through the driving gear 55, driving the top electrostatic roller 54 to rotate synchronously in the opposite direction, forming a roller clamping structure. When the bag passes between the bottom electrostatic roller 57 and the top electrostatic roller 54, it adsorbs dust, fibers and other impurities in the workshop air, ensuring that the embossed surface of the bag is clean and free of foreign objects. At the same time, multiple sets of support rollers 51 on both sides of the top electrostatic roller 54 provide support from below the bag, preventing the bag from sagging due to its own weight and causing insufficient contact with the electrostatic roller, ensuring uniform static elimination. The support rollers 51 rotate synchronously with the bag conveying, reducing bag friction loss and ensuring smooth conveying.
