Description

Technical Field

[0001] The utility model relates to the technical field of air column bag recycling, in particular to a deflating and recycling device for waste air column bags. Background Technique

[0002] The working principle of the air column bag is based on the pressure and volume changes of the gas. When the air column bag is filled with gas, the gas in the air chamber will generate pressure and keep the bag in a stable shape. This pressure can effectively protect the items in the bag from external impacts and squeezes. When the bag is subjected to external impacts or squeezes, the gas in the air chamber will be squeezed into another air chamber, thereby reducing the pressure of the bag and keeping the items inside the bag safe in a changing environment. Waste air column bags are one of the common wastes in the express delivery and packaging industries, and their treatment and recycling methods are of great significance for environmental protection and sustainable development.

[0003] The current deflating and recycling device for waste air column bags, such as the Chinese patent with the authorization announcement number CN214455391U, discloses a deflating and recycling device for waste air column bags, belonging to the technical field of air column bag recycling. It includes: a frame, a deflating component and a recycling component; the deflating component includes: a first positioning plate, a first bag winding roller, a second bag winding roller and a second positioning plate that are vertically and sequentially arranged at intervals; a first positioning hole and a second positioning hole are respectively formed on the first positioning plate and the second positioning plate; a deflating positioning box is horizontally arranged between the first bag winding roller and the second bag winding roller, a notch perpendicular to the transportation direction of the air column bag is formed below the deflating positioning box, and a strip saw is arranged below the notch, and a pressing plate is arranged inside the deflating positioning box. In the utility model, the waste air column bag is pressed down by the pressing plate, and at the same time, the air column bag is punctured and deflated by the strip saw upward through the saw teeth on the strip saw. After deflation, the air column bag is transported to the second positioning plate by the first bag winding roller and then transported to the recycling component for recycling, and the operation is more convenient, faster and more efficient.

[0004] In the above technology, the air column bag is pressed down by the pressing plate, and at the same time, the air column bag is punctured and deflated by the strip saw upward through the saw teeth on the strip saw. A one-time puncturing scheme is adopted. When some air columns of the air column bag are in an unfilled state, they cannot come into good contact with the saw teeth, resulting in the inability to puncture the unfilled air columns, and then the air column bag cannot be completely collapsed, which is not conducive to the subsequent treatment of the waste air column bag. Therefore, we propose a deflating and recycling device for waste air column bags to well solve the above drawbacks. Content of the Utility Model

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1 to 4 , a waste air column bag deflation and recycling device, including a workbench 1, the upper surface of the workbench 1 is a working surface, and the waste air column bags are sequentially punctured and deflated, squeezed and exhausted, and wound and recycled on the working surface of the workbench 1.

[0032] This embodiment further includes a mounting plate 2, an alternating puncturing mechanism 3, an air squeezing assembly 4, an automatic winding assembly 5, and a plurality of conveying rollers 6; wherein, the mounting plate 2 is fixed on the top of the workbench 1 and arranged along the length direction of the workbench 1, providing an installation space for other components in the device. In addition, each conveying roller 6 is rotatably connected to the working surface of the workbench 1 at intervals along the length direction of the workbench 1. During the winding process of the waste air column bag, the waste air column bag is in contact with the conveying roller 6, avoiding direct contact between the waste air column bag and the workbench 1, resulting in wear. When in use, the waste air column bag can be wound and recycled through the automatic winding assembly 5. During the winding process, the waste air column bag is first alternately punctured by the alternating puncturing mechanism 3 to ensure that each air column of the air column bag can be completely punctured; then, through the air squeezing assembly 4, the punctured air column bag is squeezed to discharge the air in the air column bag, so that the air column bag is completely collapsed, which is beneficial to the winding and recycling of the waste air column bag.

[0033] Specifically, the alternating puncturing mechanism 3 is arranged on the mounting plate 2 and located above the working surface of the workbench 1, and is used to alternately puncture the waste air column bag. The alternating puncturing mechanism 3 includes a pressing plate 301 arranged on the mounting plate 2 and adjustable up and down, and a plurality of pressing rollers 302 are connected to the pressing plate 301 and rotate at intervals along the moving direction of the waste air column bag. Each pressing roller 302 is parallel to the conveying roller 6 and cooperates with each other to form a conveying channel for the waste air column bag to pass through, such as Figure 1 When the waste air column bag passes through the conveying channel, the waste air column bag can be pressed tightly by the cooperation of the pressing roller 302 and the conveying roller 6, so that the waste air column bag is not easy to move up and down, thereby puncturing and deflation of the waste air column bag is convenient.

[0034] At the same time, two hollow sleeves 303 are fixed in parallel and at intervals on the top of the pressing plate 301, and a movable plate 304 slides in the vertical direction in each hollow sleeve 303. A driving assembly 305 for making the two movable plates 304 move up and down alternately is arranged on the mounting plate 2, and the two movable plates 304 can be driven by the driving assembly 305 to move up and down alternately in the corresponding hollow sleeve 303. In addition, a row of needles 306 is arranged at the bottom of each movable plate 304, and the two rows of needles 306 are arranged alternately and move through the pressing plate 301 in the vertical direction. A clearance hole 307 corresponding to each needle 306 is penetrated in the vertical direction on the workbench 1, such as Figure 4 When the needle 306 moves downward with the moving plate 304, it can pass through the yield hole 307, thereby completely puncturing the waste air column bag; in addition, since the two rows of needles 306 are staggered, the waste air column bag can be punctured at multiple points, which is convenient for the subsequent complete discharge of the air in the waste air column bag.

[0035] In this embodiment, a plurality of fixing plates 7 are fixed in parallel and at intervals on one side of the pressing plate 301 close to the mounting plate 2, and fixing bolts 8 are detachably penetrated on each fixing plate 7, and strip-shaped adjustment holes 9 corresponding to each fixing bolt 8 and arranged in the vertical direction are opened on the mounting plate 2, and the fixing bolts 8 are movable through the corresponding strip-shaped holes 9, and the nuts on the fixing bolts 8 are in close contact with the rear surface of the mounting plate 2, so that the fixing plate 7 is fixed on the mounting plate 2. The pressing plate 301 is adjusted up and down by the cooperation of the mounting plate 2, the fixing plate 7, the fixing bolts 8 and the strip-shaped adjustment holes 9. Since the volume of the waste air column bags in different batches of inflated states may be different, it is necessary to adjust the distance between the pressing roller 302 and the conveying roller 6 according to the needs. When adjusting, first loosen the nut on the fixing bolt 8 so that the fixing bolt 8 can move up and down along the strip-shaped hole 9, thereby adjusting the height of the pressing plate 301. After the adjustment is in place, tighten the nut on the fixing bolt 8, so that the fixing plate 7 is clamped and fixed on the mounting plate 2, and the structure is simple and easy to operate.

[0036] It is worth mentioning that the driving assembly 305 includes a rotating shaft 3051 which is rotatably connected to the front of the mounting plate 2 through a bearing and a shaft seat, and a servo motor 3052 which is transmission-connected to the rotating shaft 3051 is installed on the mounting plate 2, and the servo motor 3052 can drive the rotating shaft 3051 to rotate forward and reversely. A rotating block 3053 is fixedly connected to the rotating shaft 3051, and two slide grooves 3054 are penetrated in the front-back direction on the rotating block 3053, and the projections of the two slide grooves 3054 on the vertical plane are strip-shaped and symmetrically arranged along the axis of the rotating shaft 3051, and a slide bar 3055 which moves through the corresponding slide groove 3054 is fixedly connected to the top of each moving plate 304. In the initial state, the two slide grooves 3054 remain horizontal, and at this time, the two moving plates 304 are at the same height. When the servo motor 3052 is working, it drives the rotating shaft 3051 to rotate forward and reverse alternately, thereby driving the rotating block 3053 to rotate 45° counterclockwise, or 45° clockwise. When the rotating block 3053 rotates 45° counterclockwise, under the action of the slide bar 3055 and the slide slot 3054, the left movable plate 304 is at the lowest position, and the right movable plate 304 is at the highest position. At this time, the needle 306 on the left movable plate 304 passes through the corresponding clearance hole 307, thereby completely puncturing the discarded air column bag. When the rotating block 3053 rotates clockwise to the initial state, and then rotates 45° clockwise, under the action of the slide bar 3055 and the slide slot 3054, the left movable plate 304 is at the highest position, and the right movable plate 304 is at the lowest position. Thus, the needle 306 on the right movable plate 304 passes through the corresponding clearance hole 307, thereby completely puncturing the discarded air column bag. By alternating movements in this way, the discarded air column bag is punctured at multiple points, ensuring that the gas in the discarded air column bag can be completely discharged later.

[0037] In addition, the extrusion component 4 is arranged on the mounting plate 2 and is located above the working surface of the workbench 1, and is used to squeeze the punctured waste air column bag. Specifically, the extrusion component 4 includes a connecting plate 401 fixed on the front of the mounting plate 2, and a plurality of extrusion rollers 402 are connected to the connecting plate 401 and rotate at intervals along the moving direction of the waste air column bag. Each extrusion roller 402 is parallel to the conveying roller 6 and cooperates with each other to form an extrusion channel for the waste air column bag to pass through. When the punctured waste air column bag passes through the extrusion channel, the air in the waste air column bag can be squeezed out by the extrusion force, so that the waste air column bag is completely collapsed, which is convenient for subsequent winding and recycling.

[0038] Preferably, the extrusion channel is composed of a variable diameter section and a straight line section which are sequentially arranged along the moving direction of the waste air column bag. The height of the variable diameter section gradually decreases along the moving direction of the waste air column bag, which is convenient for the waste air column bag to pass through. At the same time, the air in the waste air column bag can be gradually squeezed out, which is beneficial for completely squeezing out the air in the waste air column bag through the straight line section, and flattening the waste air column bag through the straight line section, which is convenient for subsequent winding.

[0039] Finally, the automatic winding assembly 5 is arranged on the mounting plate 2 and is located above the working surface of the workbench 1, and is used to wind up the waste air column bag after extrusion. Specifically, the automatic winding assembly 5 includes a guide roller 501 and a winding roller 502 rotating on the front of the mounting plate 2, and a drive motor 503 connected to the winding roller 502 is installed on the mounting plate 2. The waste air column bag bypasses the guide roller 501 and is connected to the winding roller 502. When the drive motor 503 is working, it can drive the winding roller 502 to rotate, so as to rewind and recycle the waste air column bag after puncture and deflation.

[0040] The working principle is as follows: the waste air column bag passes through the conveying channel and the extrusion channel in sequence, then bypasses the guide roller 501 and connects to the winding roller 502, and then starts the drive motor 503, and the winding roller 502 is driven to rotate by the drive motor 503, thereby winding the waste air column bag.

[0041] During the winding process, the servo motor 3052 drives the rotating shaft 3051 to rotate forward and reverse, thereby driving the rotating block 3053 to rotate forward and reverse, and then through the cooperation of the slide groove 3054 and the slide rod 3055, drives the two movable plates 304 to move up and down alternately, so that the two rows of needles 306 alternately pass through the corresponding clearance holes 307, thereby completely puncturing the discarded air column bag at multiple points.

[0042] When the punctured waste air column bag passes through the extrusion channel, the air in the waste air column bag can be squeezed out by the extrusion force of the air squeezing roller 402, so that the waste air column bag is completely collapsed, which is convenient for subsequent winding and recycling.
