Description

Technical Field

[0001] This utility model relates to the field of air column film processing, and in particular to an air-energy film folding device. Background Technology

[0002] Air column bags, also known as cushioning air column bags, inflatable bags, bubble column bags, or columnar inflatable bags, are a new type of packaging material in the 21st century that uses natural air filling. Air column bags have excellent protective performance, are reusable, and have a lightweight design, making them widely used in various industries.

[0003] When processing air column bags, they are formed by overlapping and heat-sealing two layers of film and then inflating them. When processing smaller air column bags, a single layer of film is usually folded to create a double-layer effect. During the folding process, different products have different wrapping requirements, so the folding position will vary. When processing air column bags for various products, the equipment needs to be paused, the folding position changed, and then the equipment restarted for folding. This process is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0024] See Figures 1 to 7This utility model has a base 1 and a mounting base 2 fixedly mounted on the base 1. The mounting base 2 is symmetrically and horizontally slidably provided with a first folding plate 3 and a second folding plate 4 for guiding the two sides of the film to fold relative to each other. The first folding plate 3 and the second folding plate 4 each have an upper guide edge a, a lower guide edge b, a proximal edge c, and a folding edge d. The upper guide edge a is located close to the mounting base 2, and the lower guide edge b is located away from the mounting base 2. The proximal edges c of the first folding plate 3 and the second folding plate 4 are arranged opposite each other and can form a pressing against each other as the first folding plate 3 and the second folding plate 4 slide. The base 1 is fixedly provided with a transport component 5 for transporting the folded film. The transport component 5 is located below the lower guide edge b. The base 1 is also provided with a fold line guide strip 6 for guiding the film into the transport component 5. The mounting base 2 is also fixedly provided with a first driving device 7 for driving the first folding plate 3 to slide and a second driving device 8 for driving the second folding plate 4 to slide.

[0025] By sliding the first folding plate 3 and the second folding plate 4, the area ratio of the film on the first folding plate 3 and the second folding plate 4 can be changed, so that the folded area of ​​the film is different after passing the folding edge d, thereby changing the folding position of the film; the folding position of the film can be adjusted without stopping the film processing, which is efficient and convenient.

[0026] The folding edges d of the first folding plate 3 and the second folding plate 4 are connected to the upper guide edge a and the lower guide edge b on the corresponding first folding plate 3 and second folding plate 4. The extension line of one end of the folding edge d on the first folding plate 3 connected to the lower guide edge b on the first folding plate 3 intersects with the extension line of one end of the folding edge d on the second folding plate 4 connected to the lower guide edge b on the second folding plate 4 to form a V-shape.

[0027] The mounting base 2 is provided with a horizontally extending slot 21, and symmetrical sliding grooves are provided on the side wall of the slot 21; a first connecting strip 31 that can be inserted into the slot 21 is fixed on the first folding plate 3, and a first sliding block that can slide with the sliding groove is fixed on the first connecting strip 31; a second connecting strip 41 that can be inserted into the slot 21 is fixed on the second folding plate 4, and a second sliding block that can slide with the sliding groove is fixed on the second connecting strip 41; the second folding plate 4 is slidably mounted on the mounting base 2 through the sliding engagement of the second sliding block and the sliding groove; both the first connecting strip 31 and the second connecting strip 41 are provided with horizontally extending threads. The first drive device 7 has a first screw 71 fixedly installed on its drive end, which can form a threaded engagement with the threaded hole on the first connecting strip 31. The second drive device 8 has a second screw 81 fixedly installed on its drive end, which can form a threaded engagement with the threaded hole on the second connecting strip 41. The first folding plate 3 is horizontally slidably mounted on the mounting base 2 through the threaded engagement of the first screw 71 with the threaded hole on the first connecting strip 31 and the sliding engagement of the first sliding block with the sliding groove. The second folding plate 4 is horizontally slidably mounted on the mounting base 2 through the threaded engagement of the second screw 81 with the threaded hole on the second connecting strip 41 and the sliding engagement of the second sliding block with the sliding groove.

[0028] Because the sliding speed of the first folding plate 3 and the second folding plate 4 is relatively slow when the threads are engaged, the thread engagement allows the first folding plate 3 and the second folding plate 4 to slide precisely on the mounting base 2.

[0029] The mounting base 2 is provided with a guide groove 22 that is parallel to the slot 21. The first folding plate 3 is fixedly provided with a first support bar 32 that can slide with the guide groove 22. The second folding plate 4 is fixedly provided with a second support bar 42 that can slide with the guide groove 22.

[0030] The first support bar 32 and the second support bar 42 can slide along with the first connecting bar 31 and the second connecting bar 41 respectively. The first support bar 32 and the second support bar 42 can provide a certain support force to the first folding plate 3 and the second folding plate 4 to ensure the stability of the first folding plate 3 and the second folding plate 4.

[0031] The transport assembly 5 includes a first transport support 51, a second transport support 52, a first transport roller 53, and a second transport roller 54. The first transport support 51 and the second transport support 52 are symmetrically fixed on the base 1. The first transport support 51 is located close to the mounting base 2, and the second transport support 52 is located away from the mounting base 2. The first transport roller 53 and the second transport roller 54 are symmetrically rotated between the first transport support 51 and the second transport support 52. Both ends of the first transport roller 53 and the second transport roller 54 are respectively rotated on the first transport support 51 and the second transport support 52. A transport channel 9 is formed between the first transport roller 53 and the second transport roller 54, through which the folded film can pass.

[0032] The fold guide strip 6 includes a fixed end 61 fixedly mounted on the base 1 at the bottom and a guide end 62 fixedly mounted on the top of the fixed end 61 and extending toward the second transport support 52. The guide end 62 is located directly above the transport channel 9. The end of the guide end 62 extending toward the second transport support 52 is provided with a fold guide slope 63 for guiding the formation of fold lines in the film.

[0033] The contact surface of the folding guide slope is located on the same plane as the surfaces of the first folding plate 3 and the second folding plate 4.

[0034] The top of the mounting base 2 is fixedly provided with a guide assembly 10 for guiding the film into the first folding plate 3 and the second folding plate 4. The guide assembly 10 includes a first guide support 101 and a second guide support 102 arranged symmetrically on the left and right sides, and also includes a guide roller 103 that is rotatably arranged on the first guide support 101 and the second guide support 102 at both ends. The axial direction of the guide roller 103 is consistent with the extension direction of the upper guide edge a.

[0035] The upper guide edge a, lower guide edge b, adjacent edge c, folded edge d, and folded guide strip 6 mentioned above are all chamfered to prevent the film from being damaged when it comes into contact with these positions.

[0036] The working principle of this utility model is as follows: After the film passes through the guide roller 103, it passes through the first folding plate 3 and the second folding plate 4 to form a fold. The folded film enters the transport channel 9 and is pulled through the transport channel 9 by an external device to enter the next process. During this process, the contact surface of the fold line guiding inclined surface 63 contacts the inner fold line on the folded film to guide the formation of the film fold line.

[0037] When it is necessary to change the position of the film folding, the first drive device 7 and the second drive device 8 drive the first screw 71 and the second screw 81 to rotate respectively. Then, the threaded engagement between the first screw 71 and the threaded hole on the first connecting strip 31 and the threaded engagement between the second screw 81 and the threaded hole on the second connecting strip 41 are used to drive the first folding plate 3 and the second folding plate 4 to slide on the mounting base 2. After the film is folded by the folding edge d on the first folding plate 3 and the second folding plate 4 after sliding, the position of the film folding changes. Then, under the guidance of the folding guide slope 63, a new fold line is formed, and the film enters the next process.

[0038] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
