Description

Technical Field

[0001] This utility model relates to the field of film composite auxiliary equipment technology, and in particular to an online punching device for the processing of plastic packaging bags. Background Technology

[0002] Plastic packaging bags are containers made primarily of plastic, used to package various items for convenient transportation, storage, and use. The manufacturing process of plastic packaging bags mainly includes core steps such as raw material processing, film forming, printing, cutting, and sealing.

[0003] After printing, plastic film needs to be perforated at its edges during the final cutting and sealing process to create hook holes for the subsequent plastic packaging bags. Currently, existing perforation devices are cumbersome to adjust when perforating plastic films of different sizes. If perforation were performed after the plastic packaging bags were already processed, production efficiency would be significantly reduced.

[0004] Therefore, it is desirable to provide an online punching device for the processing of plastic packaging bags, in order to solve the above-mentioned technical problems. Utility Model Content

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] This embodiment provides an online punching device for processing plastic packaging bags, comprising two support strips 1, a moving mechanism, and a punching mechanism.

[0035] The two support strips 1 are fixed to both sides of the external conveying bracket along the conveying direction of the plastic film; as shown... Figure 1 As shown, the top of the support strip 1 is provided with a rack 2 along its length.

[0036] like Figure 2 As shown, the moving mechanism includes a moving base 3, a rotating shaft 4, and a lead screw 5; the moving base 3 spans two supporting strips 1; the rotating shaft 4 is horizontally rotatably mounted on the moving base 3 and is perpendicular to the conveying direction of the plastic film; as shown... Figure 3 As shown, gears 6 are fixedly fitted at both ends of the rotating shaft 4 directly above the rack 2, and the gears 6 mesh with the corresponding racks 2. With this configuration, by rotating the rotating shaft 4, the moving seat 3 will move linearly along the two supporting racks 1 because the gears 6 mesh with the racks 2 on the supporting strips 1.

[0037] In this embodiment, as Figure 3 As shown, the support bar 1 has a groove 7 along its length on the inner side of the rack. Both ends of the rotating shaft 4 are fitted with pulleys 8 directly above the groove 7, with the lower part of each pulley 8 located within its corresponding groove 7. Through this arrangement, the grooves 7 on the two support bars 1 guide the movable seat 3, effectively preventing it from deviating during movement and causing the gear 6 to jam on the rack 2.

[0038] The lead screw 5 is horizontally rotatably mounted on the movable seat 3 and parallel to the rotating shaft 4; the punching mechanism includes a slider 9, a mounting base 10, a cylinder 11, and a punching knife 12; the slider 9 is threaded onto the lead screw 5; the mounting base 10 is detachably fixed to the slider 9; the cylinder 11 is located on the top of the mounting base 10, and the piston rod of the cylinder 11 passes vertically downward through the top of the mounting base 10; the punching knife 12 is located at the end of the piston rod of the cylinder 11.

[0039] When the above-mentioned online punching device punches holes, it first rotates the rotating shaft 4, so that the moving seat 3 moves to a suitable position on the two support strips 1, and then rotates the lead screw 5, so that the slider 9 moves on the lead screw 5, so that the punching knife 12 connected to the cylinder 11 is directly above the suitable position of the conveyed plastic film; when the plastic film conveyed on the conveying device passes through the mounting seat, the piston rod on the cylinder 11 moves downward, and the punching knife 12 performs a punching operation on the designated position of the plastic film; the inventor should explain that the plastic film conveyed online can be punched at a designated edge position by adjusting the conveying speed in conjunction with the piston rod movement speed of the cylinder 11.

[0040] In this embodiment, specifically, as Figure 4 As shown, the lower part of the mounting base 10 has a limiting groove 13, and a through hole 14 is provided on the limiting groove 13 directly below the piston rod of the cylinder 11; with this arrangement, the limiting groove 13 can effectively limit the plastic film conveyed online; after the stamping knife 12 on the cylinder 11 successfully stamps the plastic film conveyed online, the stamped waste will fall through the through hole 14.

[0041] Furthermore, a guide bar 15 is horizontally fixed on the movable seat 3, and the guide bar 15 is parallel to the rotating shaft 4. The slider 9 is slidably sleeved on the guide bar 15. The through hole 14 on the mounting seat 10 is located diagonally above the guide bar 15. With this arrangement, on the one hand, the slider 9 will not wobble when moving on the lead screw 5, ensuring the accuracy of the stamping operation. On the other hand, the through hole 14 on the mounting seat 10 is located diagonally above the guide bar 15, so the waste original sheet that falls off during stamping will fall into the collection frame on the conveyor bracket through the through hole 14, instead of falling onto the guide bar 15 and affecting the movement of the slider 9.

[0042] In this embodiment, as Figure 5As shown, the online punching device also includes a limiting mechanism, which includes a gantry frame 16 and two limiting sliders 17. The gantry frame 16 is positioned at the feed end of the two supporting strips 1, and the two limiting sliders 17 are slidably and symmetrically positioned on the top of the gantry frame 16. Each of the two limiting sliders 17 has a limiting groove 18 on its facing side. Each of the two limiting sliders 17 has a set screw 19 on its top. With this configuration, by moving the position of the two limiting sliders 17 on the gantry frame 16, different widths of plastic film can be adapted and effectively limited. Then, the position is fixed by the set screw 19 to ensure that the conveyed plastic film is flat during punching.

[0043] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
