Description

Technical Field

[0001] This utility model relates to the technical field of paper processing equipment, and in particular to an accordion folding paper bubble press. Background Technology

[0002] Currently used cushioning packaging bags are made of woven foamed plastic that wraps around the outside of the product, such as mesh bags used to wrap fruit, providing cushioning protection. However, these packaging bags are not easily biodegradable and are not environmentally friendly. Therefore, a substitute cushioning packaging material is needed. Existing materials include honeycomb paper, which meets environmental requirements. However, for larger or irregularly sized items, custom-made honeycomb paper may be necessary. Therefore, a more versatile cushioning paper is needed, such as bubble wrap. Manually made bubble wrap is inefficient and difficult to fold, often deforming during folding. Therefore, a device is needed to produce bubble wrap that can be folded without deformation and is easy to transport. Bubble wrap, when folded, resembles an accordion, hence its other name, accordion paper. Utility Model Content

[0003] The purpose of this invention is to provide an accordion folding paper bubble press to overcome the shortcomings of the existing technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An accordion folding paper bubble press has the advantages of high-efficiency production, precise bubble pressing and easy folding, and solves the problems of existing cushioning packaging materials being difficult to degrade, having limited applicability, and being inefficient and easily deformed when folded manually.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an accordion-style folding paper bubble pressing machine, comprising a frame, a paper feeding mechanism, a bubble pressing assembly, and a cutting assembly. The paper feeding mechanism is located at the front end of the frame and is used to continuously feed paper to the bubble pressing assembly; the bubble pressing assembly is located behind the paper feeding mechanism and is used to perform concave-convex bubble pressing on the paper; the cutting assembly is located behind the bubble pressing assembly and is used to form equidistant dotted line cutting areas on the bubble-pressed paper. The bubble pressing assembly and the cutting assembly are connected by a unified transmission device and driven by the same drive motor.

[0006] In a preferred embodiment of this invention, the paper feeding mechanism includes several sets of paper feeding rollers. Each set consists of two upper and lower rubber paper feeding rollers. A spring applies pressure between the upper and lower rollers to clamp and feed the paper forward. Both ends of each paper feeding roller set are fixed to the frame via bearing seats, and a gear is provided at one end of each set. The gears between adjacent sets mesh to ensure synchronous rotation of all paper feeding roller sets.

[0007] In a preferred embodiment of this invention, the bubble-pressing assembly includes upper and lower bubble-pressing rollers. The surface of each bubble-pressing roller has multiple raised structures arranged regularly, with recessed areas formed between adjacent raised structures to create a uniform embossed bubble structure on the paper surface. Both ends of the bubble-pressing rollers are mounted on the frame via bearings, and one end of one of the bubble-pressing rollers is equipped with a transmission gear. This transmission gear meshes with a gear in a transmission device, thereby enabling the rotational movement of the bubble-pressing roller.

[0008] In a preferred embodiment of this invention, the cutting assembly includes upper and lower cutting rollers. The surfaces of the cutting rollers are provided with radially arranged blades, and the distance from the top of each blade to the axis of the cutting roller is equal to the maximum radius of the bubble-pressing roller. Both ends of the cutting rollers are mounted on a frame via bearings, and one end of one of the cutting rollers is equipped with a transmission gear. This transmission gear meshes with a gear in a transmission device, thereby achieving the rotational movement of the cutting roller. The cutting rollers and the bubble-pressing rollers rotate at the same speed to ensure that the interval length of the dotted lines formed by each cut is consistent.

[0009] In a preferred embodiment of this invention, the transmission device includes a main transmission gearbox, which contains multiple sets of gears, each set meshing with the transmission gears of the blister roller and the cutting roller. One end of the main transmission gearbox is connected to the output shaft of a drive motor, which transmits power to the blister roller and the cutting roller through the main transmission gearbox, thereby ensuring their synchronous operation.

[0010] In a preferred embodiment of this invention, a folding guide mechanism is provided at the rear end of the frame. This folding guide mechanism includes a set of guide plates and a set of limiting strips. The guide plates are fixed to both sides of the frame to guide the paper along a fixed path. The limiting strips are located inside the guide plates to limit lateral deviation of the paper. A folding groove is provided at the end of each guide plate, the width of which matches the thickness of the bubble wrap to help maintain the paper's neatness during folding.

[0011] As a preferred embodiment of this invention, the raised structure of the bubble pressing roller is made of wear-resistant material, and its surface is hardened to improve its service life. The blade of the cutting roller is made of high-hardness alloy steel, and the cutting edge of the blade is precision ground to ensure cutting accuracy.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a paper feeding mechanism that uses multiple sets of paper feeding rollers to continuously transport paper. The gear meshing between the paper feeding roller sets ensures the stability of paper transport and avoids processing errors caused by paper slippage.

[0013] This invention utilizes a bubble-pressing component, employing the raised structure on the surface of the bubble-pressing roller to uniformly press bubbles into the paper, creating a regular uneven structure on the paper surface and thus improving its cushioning performance. The bubble-pressing roller and the cutting roller are connected by a unified transmission device, ensuring their synchronous operation and resulting in consistent dotted line intervals for each cut.

[0014] This invention utilizes a cutting assembly to create equidistant dotted-line cutting areas on the bubble-pressed paper, enabling the bubble-pressed paper to be folded in alignment to a fixed length. The blades of the cutting roller are made of high-hardness alloy steel, ensuring cutting precision and durability.

[0015] This invention utilizes a folding guide mechanism, employing guide plates and limiting strips to guide and limit the paper, preventing it from shifting during the folding process. The folding groove design keeps the paper neat during folding, preventing deformation.

[0016] In summary, this utility model achieves efficient production, precise bubble compression, and easy folding through the synergistic effect of the paper feeding mechanism, bubble compression component, cutting component, and folding guide mechanism. It solves the problems of existing cushioning packaging materials being difficult to degrade, having limited applicability, and being inefficient to produce manually and easily deformed when folded.

[0023] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings: An accordion folding paper bubble press, the overall structure of which is as follows: Figure 1As shown, the device includes a frame 1, a paper feeding mechanism, a bubble pressing assembly, a cutting assembly, and a folding guide mechanism. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] The frame 1 serves as the main support for the entire equipment. Made of rigid materials, it possesses sufficient strength and stability to support other components. The paper feeding mechanism is located at the front end of the frame 1 and continuously transports paper to subsequent workstations. The paper feeding mechanism consists of several sets of paper feeding rollers 2. Each set of paper feeding rollers 2 includes upper and lower rubber paper feeding rollers. These rollers are spring-loaded to clamp and transport the paper forward. Figure 2 As shown, both ends of the paper feed roller group 2 are fixed to the frame 1 via bearing seats, and each end of the paper feed roller group 2 is equipped with a gear, with the gears meshing between adjacent paper feed roller groups 2. This gear meshing method ensures that each paper feed roller group 2 can rotate synchronously, thereby ensuring that the paper will not shift or slip during the conveying process. The rubber material of the paper feed roller group 2 and the pressure applied by the spring work together to keep the paper stable during the conveying process and avoid slippage caused by insufficient friction.

[0025] The embossing assembly is located behind the paper feeding mechanism and is used to emboss and bubble the paper. For example... Figure 3 As shown, the bubble-pressing assembly includes two bubble-pressing rollers 3, one above the other. The surface of each roller 3 has multiple regularly arranged protrusions 10, with recessed areas formed between adjacent protrusions. These protrusions 10 are evenly distributed, and their shape and size are designed according to the desired bubble-pressing effect. Both ends of the bubble-pressing roller 3 are mounted on the frame 1 via bearings. One end of one of the bubble-pressing rollers 3 is equipped with a transmission gear, which meshes with a gear in the transmission device 5. The transmission device 5 includes a main transmission gearbox containing multiple gear sets, each meshing with the transmission gears of the bubble-pressing roller 3 and the cutting roller 4. One end of the main transmission gearbox is connected to the output shaft of the drive motor 6. The drive motor 6 transmits power to the bubble-pressing roller 3 and the cutting roller 4 through the main transmission gearbox, thus ensuring synchronous operation. The protrusions 10 of the bubble-pressing roller 3 are made of wear-resistant material and have undergone hardening treatment to improve their service life. When the paper enters the bubble pressing assembly from the paper feeding mechanism, the upper and lower bubble pressing rollers 3 squeeze the paper by rotating, so that a uniform uneven structure is formed on its surface.

[0026] The cutting component is located behind the bubble compression component and is used to form equidistant dotted line cutting areas on the bubble-compressed paper. For example... Figure 4As shown, the cutting assembly includes two cutting rollers 4, one upper and one lower, with radially arranged blades 11 on the surface of each roller 4. The distance from the top of the blade 11 to the axis of the cutting roller 4 is equal to the maximum radius of the bulging roller 3, ensuring a moderate cutting depth without damaging the overall structure of the paper. Both ends of the cutting roller 4 are mounted on the frame 1 via bearings. One end of one of the cutting rollers 4 is equipped with a drive gear, which meshes with a gear in the transmission device 5. Because the cutting roller 4 and the bulging roller 3 are connected via a unified transmission device 5, they rotate at the same speed, resulting in consistent dotted line intervals for each cut. The blades 11 of the cutting roller 4 are made of high-hardness alloy steel and precision-ground to ensure cutting accuracy and durability. When the paper enters the cutting assembly from the bulging assembly, the two cutting rollers 4 rotate to cut the paper, forming equidistant dotted line cutting areas.

[0027] The folding guide mechanism is located at the rear end of frame 1 to help keep the paper neat during the folding process. For example... Figure 5 As shown, the folding guide mechanism includes a set of guide plates 7 and a set of limiting strips 8. The guide plates 7 are fixed to both sides of the frame 1 to guide the paper along a fixed path; the limiting strips 8 are located inside the guide plates 7 to limit lateral deviation of the paper. A folding groove 9 is provided at the end of each guide plate 7. The width of the folding groove 9 matches the thickness of the bubble wrap to help keep the paper neat during folding. When the paper enters the folding guide mechanism from the cutting assembly, the guide plates 7 and the limiting strips 8 work together to move the paper along the predetermined path and prevent lateral deviation. The design of the folding groove 9 further ensures that the paper does not deform during folding.

[0028] The working process of this utility model is as follows: First, the paper is continuously conveyed to the bubble pressing assembly by the paper feeding roller group 2 of the paper feeding mechanism. The paper feeding roller group 2 rotates synchronously through gear meshing to ensure the stability of paper feeding. Subsequently, the paper enters the bubble pressing assembly, where the upper and lower bubble pressing rollers 3 squeeze the paper by rotating, forming a uniform concave-convex structure on its surface. The bubble-pressed paper continues to enter the cutting assembly, where the upper and lower cutting rollers 4 cut the paper by rotating, forming equidistant dotted line cutting areas. Finally, the paper enters the folding guide mechanism, moving along a fixed path under the action of the guide plate 7 and the limiting strip 8, and finally completing the folding through the folding groove 9. Throughout the process, the drive motor 6 transmits power to the bubble pressing rollers 3 and the cutting rollers 4 through the transmission device 5, ensuring their synchronous operation, thereby achieving the technical effects of high-efficiency production, precise bubble pressing, and easy folding.

[0029] Through a rational layout and precise coordination, the various components of this invention achieve continuous paper feeding, uniform bubble pressing, equidistant cutting, and neat folding. The gear meshing design of the paper feeding mechanism ensures the stability of paper feeding. The raised structure 10 of the bubble pressing component and the blade 11 of the cutting component are made of wear-resistant material and high-hardness alloy steel, respectively, improving the service life and processing accuracy of the equipment. The guide plate 7, the limiting strip 8, and the folding groove 9 of the folding guide mechanism work together to prevent the paper from shifting or deforming during the folding process.

[0030] This invention solves the problems of low efficiency and easy deformation during folding in traditional manual paper blister pack production through a reasonable structural layout and precise component matching. The gear meshing design of the paper feeding mechanism ensures the stability of paper transport. The protruding structure 10 of the blister pack assembly and the blade 11 of the cutting assembly are made of wear-resistant materials and high-hardness alloy steel, respectively, significantly improving the service life and processing accuracy of the equipment. The design of the folding guide mechanism further optimizes the neatness and consistency of the paper during the folding process, providing reliable technical support for practical applications.
