Description

Technical Field

[0001] This utility model relates to the field of air column bag processing technology, and in particular to a column splitting device for air column bag processing. Background Technology

[0002] Air column bag processing is a process of using thermoplastic films (such as polyethylene PE, nylon PA, etc.) to make cushioning packaging materials with independent air column structures through specific processes. The final air column bags can be used for shockproof and cushioning packaging of products after being inflated. They are widely used in industries such as electronics, home appliances, and food. Air column bag processing requires column separation.

[0003] The existing column separation device for air column bag processing has some shortcomings: the heat sealing work requires the air column bag to be moved to the next process after the boundary is cut and shaped. During the movement, the air column bag may be displaced, causing the position to be deviated and affecting the column separation work of the air column bag.

[0004] To address these issues, those skilled in the art have proposed a column splitting device for processing air column bags. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a column splitting device for processing air column bags, comprising a worktable, a sleeve installed on one side of the worktable, and a double-layer film for air column bags being sleeved on the surface of the sleeve;

[0009] The pressing mechanism is located on both sides above the worktable and arranged back and forth along the membrane material conveying direction to apply pressing force to the membrane material.

[0010] A cutting mechanism is installed on the corresponding pressing mechanism;

[0011] The slitting and heat-sealing mechanism is located directly above the worktable and is used to slitting and heat-sealing the cut film material.

[0012] As a preferred embodiment of the column splitting device for processing air column bags according to this utility model, a mounting groove is opened at the center of the workbench surface, a plurality of electric heating rods are horizontally arranged inside the mounting groove, a heat-conducting plate is horizontally installed on the inner wall of the mounting groove in contact with the workbench surface, and the surface of the heat-conducting plate is coated with a wear-resistant coating.

[0013] As a preferred embodiment of the column splitting device for processing air column bags according to this utility model, the worktable surface is provided with rectangular grooves at the four corners near the heat-conducting plate, and a positioning plate is installed on the inner wall of the rectangular groove, the surface of the positioning plate being flush with the surface of the worktable.

[0014] As a preferred embodiment of the column splitting device for processing air column bags according to this utility model, the outer wall of the workbench is fixedly installed with connecting frames near both ends, and one end of the two connecting frames is equipped with the same top plate, which is located directly above the workbench.

[0015] As a preferred embodiment of the column splitting device for processing air column bags according to this utility model, the pressing mechanism is located above the corresponding positioning plate, the pressing mechanism includes an electric cylinder, the electric cylinder is installed on the top inner wall of the top plate, and a pressure plate is installed at one end of the extension rod of the electric cylinder.

[0016] In a preferred embodiment of the column splitting device for processing air column bags according to this utility model, the cutting mechanism is installed on the surface of the pressure plate. The cutting mechanism includes a slide rail, which is installed on the surface of the pressure plate. A slider is slidably disposed on the surface of the slide rail. A vertical rod is installed on the surface of the slider. A connecting plate is sleeved on the outer wall of the vertical rod. A cutting blade is installed on one side of the bottom outer wall of the connecting plate. The cutting blade is attached to one side of the outer wall of the pressure plate.

[0017] As a preferred embodiment of the column splitting device for processing air column bags according to this utility model, the splitting and heat sealing mechanism includes a hydraulic cylinder, which is installed at the center of the inner wall of the top plate. A horizontal plate is installed at the bottom end of the extension rod of the hydraulic cylinder. Sliding strips are provided on both sides of the bottom outer wall of the horizontal plate. A square platform is slidably sleeved on the surface of the two sliding strips. Multiple slots are arranged in an array on the bottom outer wall of the square platform.

[0019] The beneficial effects of the column splitting device for processing air column bags according to this utility model:

[0020] The pressing mechanism uses an electric cylinder to drive the pressure plate to press down and fix the film material, and uses the cutting blades of the cutting mechanism on both sides to cut the film, thereby forming a single air column bag, which facilitates the subsequent column splitting of the air column bag.

[0021] A hydraulic cylinder moves a square platform downwards, then a micro-cylinder moves the blade downwards, cutting the air column bag into multiple independent air column units. The micro-cylinder then retracts the blade into a slot. The handle pulls the square platform from one side of the slide bar to the other, positioning the convex heat-conducting plate directly above the cut position. The hydraulic cylinder then moves the convex heat-conducting plate downwards. The convex heat-conducting plate and the heat-conducting plate are heated by electric heating rods two and one, respectively, to perform heat sealing from both ends of the film. This melts the cut areas of the independent air column units, allowing them to cool and reform into a single unit, thus completing the separation of the air column bag. Direct heat sealing after separating the air column units avoids deviations at the film joints during film movement, ensuring successful heat sealing at the joints. Attached Figure Description

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0032] Reference Figures 1 to 3 This is the first embodiment of the present utility model. This embodiment provides a column splitting device for processing air column bags, which can achieve the effect of directly performing heat sealing work after splitting air column units. It includes a workbench 100, a sleeve 101 installed on one side of the workbench 100, and a double-layer film for air column bags is sleeved on the surface of the sleeve 101.

[0033] The pressing mechanism 200 is located on both sides above the worktable 100 and is arranged back and forth along the film material conveying direction. It is used to apply pressing force to the film material.

[0034] The cutting mechanism 300 is installed on the corresponding pressing mechanism 200;

[0035] The slitting and heat-sealing mechanism 400 is located directly above the worktable 100 and is used to slitting and heat-sealing the cut film material.

[0036] Specifically, a mounting groove is provided at the center of the surface of the workbench 100. Multiple electric heating rods are horizontally arranged inside the mounting groove. A heat-conducting plate 102 is horizontally installed on the inner wall of the mounting groove, which is in contact with the surface of the workbench 100. The surface of the heat-conducting plate 102 is coated with a wear-resistant coating.

[0037] Furthermore, rectangular grooves are provided at the four corners of the workbench 100 near the heat-conducting plate 102, and positioning plates 105 are installed on the inner walls of the rectangular grooves. The surface of the positioning plates 105 is flush with the surface of the workbench 100.

[0038] Among them, the outer wall of the workbench 100 is fixedly installed with connecting brackets 103 near both ends, and one end of the two connecting brackets 103 is equipped with the same top plate 104, which is located directly above the workbench 100.

[0039] It should be noted that the pressing mechanism 200 is located above the corresponding positioning plate 105. The pressing mechanism 200 includes an electric cylinder 201, which is installed on the top inner wall of the top plate 104. A pressure plate 202 is installed at one end of the extension rod of the electric cylinder 201.

[0040] The cutting mechanism 300 is installed on the surface of the pressure plate 202. The cutting mechanism 300 includes a slide rail 301, which is installed on the surface of the pressure plate 202. A slider 302 is slidably arranged on the surface of the slide rail 301. A vertical rod 303 is installed on the surface of the slider 302. A connecting plate 304 is sleeved on the outer wall of the vertical rod 303. A cutting blade 305 is installed on one side of the bottom outer wall of the connecting plate 304. The cutting blade 305 is attached to one side of the outer wall of the pressure plate 202.

[0041] In use, after opening the sleeve 101, the double-layer film is fitted onto the sleeve 101, and then the film is pulled out so that it is laid flat with the four corners on the surface of the four positioning plates 105. Then, the electric cylinder 201 is started to drive the pressure plate 202 to move down and fix the film. Then, the operator pulls the cutting blade 305 through the vertical rod 303 to separate the film from the film on the sleeve, forming an independent air column bag. Then, the dividing and heat sealing mechanism 400 is started to divide and heat seal the cut film material. After cooling, the divided air column bag is obtained. After inflating it, it becomes a full air column bag. Example

[0042] Reference Figures 1 to 5This is the second embodiment of the present invention. Unlike the previous embodiment, the dividing and heat-sealing mechanism 400 includes a hydraulic cylinder 401. The hydraulic cylinder 401 is installed at the center of the inner wall of the top plate 104. A horizontal plate 402 is installed at the bottom end of the extension rod of the hydraulic cylinder 401. Slide strips 403 are provided on both sides of the bottom outer wall of the horizontal plate 402. A square platform 404 is slidably sleeved on the surface of the two slide strips 403. Multiple slots 408 are arranged in an array on the bottom outer wall of the square platform 404. Miniature cylinders 409 are vertically installed on both sides of the top inner wall of the slots 408. The same blade 406 is installed at the bottom end of the extension rod of the corresponding two miniature cylinders 409.

[0043] Specifically, a strip groove is opened on the outer wall of the bottom of the square platform 404 near the blade 406. An electric heating rod 2 is installed inside the strip groove. A convex heat-conducting plate 407 is installed on the inner wall of the strip groove near the lower part of the electric heating rod 2. The number of convex heat-conducting plates 407 is the same as that of the blade 406.

[0044] In use, the hydraulic cylinder 401 drives the square platform 404 to move down, and then the micro cylinder 409 is activated to drive the blade 406 to move down, cutting the air column bag into multiple independent air column units. Then, the micro cylinder 409 retracts the blade 406 into the slot 408. The handle 405 is used to pull the square platform 404 from one side of the slide bar 403 to the other side, so that the convex heat-conducting plate 407 is directly above the cutting position of the blade 406. Then, the hydraulic cylinder 401 drives the convex heat-conducting plate 407 to move down. The convex heat-conducting plate 407 and the heat-conducting plate 102 are heated by the second electric heating rod and the first electric heating rod, respectively, so as to perform heat sealing from both ends of the film, so that the cut part of the independent air column unit melts and then cools down to form a whole again, thus completing the column division of the air column bag.

[0045] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
