DETAILED DESCRIPTION

[0022] Example:

[0023] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] As attached Figure 1-5 As shown, a large bubble film cutting device of this embodiment includes a film drawing support 1, a coil material support 2 and a film cutting assembly, wherein the film cutting assembly is arranged at the connection between the film drawing support 1 and the coil material support 2; the film drawing support 1 includes a slide rail 3 and a film drawing rod assembly slidably arranged on the slide rail 3, the film drawing rod assembly includes a sliding pull rod 4, a film clamping mechanism and a pull rod driving mechanism, the film clamping mechanism is used to clamp the large bubble film material, and the pull rod driving mechanism is used to drive the film drawing rod assembly to move back and forth along the slide rail 3; the coil material support 2 is used to support and place the large bubble film coil; the film cutting assembly includes a cutting knife mechanism that can move relative to the film drawing support 1 to cut the large bubble film material. The utility model uses a moving film drawing rod assembly to drag the large bubble film to move forward, and the cutting knife mechanism moves and cuts it. The overall and specific structural settings of each component are more reasonable, which is convenient for operation and control, and convenient for loading and unloading operations. It has the characteristics of good applicability, fast film cutting speed, high efficiency, and high cutting quality.

[0026] As shown in the accompanying drawings, it is feasible that the film clamping mechanism can be a plurality of pneumatic clamps 5 arranged at intervals on the sliding rod 4. For example, three pneumatic clamps 5 are arranged at intervals in this embodiment, which are arranged at both ends and the middle of the sliding rod 4, and the clamping or loosening of the pneumatic clamps 5 is driven by a clamping cylinder 6.

[0027] In this embodiment, the rod driving mechanism includes a rod motor 7 and a driving wheel 8 arranged at both ends of the sliding rod 4. Longitudinal rails 9 are arranged on both sides of the film-drawing support 1. The driving wheel 8 is in contact with the longitudinal rails 9 and driven by the rod motor 7. In this way, the film-drawing rod assembly can be driven to move back and forth along the longitudinal rails 9 by the forward and reverse rotation of the rod motor 7. Specifically, when the sliding rod 4 moves close to the film cutting assembly, the clamping cylinder 6 drives the pneumatic clamp 5 to close and clamp the end of the large bubble film material, and then the rod motor 7 drives the sliding rod 4 to move a set distance toward the tail end of the film-drawing support 1. After the film cutting assembly cuts off the large bubble film material, the pneumatic clamp 5 is released to complete the film cutting of a large bubble film, and the film-drawing rod assembly is reset for the next round of film cutting.

[0028] In this embodiment, the cutting mechanism includes a circular cutter 10, a cutter motor 11, a cutter track and a cutter track motor 12. The circular cutter 10 is mounted on the rotating shaft of the cutter motor 11. The cutter track motor 12 is used to drive the circular cutter 10 and the cutter motor 11 to move back and forth along the cutter track. In this way, the circular cutter 10 is driven to rotate by the cutter motor 11 to cut the large bubble film material. At the same time, the circular cutter 10 and the cutter motor 11 are driven by the cutter track motor 12 to move from the left side of the film cutting component to the right side to complete the cutting of a large bubble film. The next large bubble film is cut by moving from the left side of the film cutting component to the right side. The reciprocating motion can realize the film cutting action, reduce the resetting action of the cutter mechanism, and improve the film cutting efficiency.

[0029] It is easy to understand, referring to the accompanying drawings, that the knife track of this embodiment is arranged horizontally along the film-drawing bracket 1, and specifically includes a slider knife track 13 and a rack knife track 14. The knife track motor 12 is meshed with the rack knife track 14 through gears for transmission. In this way, one side of the cutting mechanism serves as the power side, and provides smooth travel power under the gear meshing transmission of the knife track motor 12, while the other side of the cutting mechanism slides along the slider knife track 13, thereby achieving smooth travel and cutting of the circular tool 10 and the tool motor 11, and ensuring the cutting quality of the large bubble film material.

[0030] In a preferred embodiment, as shown in the accompanying drawings, the film cutting assembly includes a first pressure rod mechanism arranged at the front side of the cutter mechanism, the first pressure rod mechanism includes a first pressure rod 15 and a first vertical cylinder 16, and the first pressure rod 15 is driven to move up and down by the first vertical cylinder 16. The function of the first pressure rod 15 in this embodiment is to achieve fixed-length cutting of the large-bubble film material by cooperating with the action of the film-pulling rod assembly, specifically, the film-pulling rod assembly drags the large-bubble film material at a set speed for feeding, and stops when the set time is reached. At the same time, the first vertical cylinder 16 drives the first pressure rod 15 to move downward, clamping the large-bubble film material to prevent it from continuing to feed due to the inertia of the movement, that is, to achieve fixed-length feeding of the large-bubble film material. At this time, the cutter mechanism can perform a cutting action to cut the large-bubble film material into small pieces of material of a set length.

[0031] In order to facilitate the pneumatic clamp 5 of the film-pulling rod assembly to perform the clamping action, in this embodiment, the film cutting assembly includes a horizontal cylinder mechanism 17, and the horizontal cylinder mechanism 17 is arranged in the horizontal direction, and is used to drive the cutting mechanism and the first pressure rod mechanism to move back and forth in the horizontal direction. In this way, before performing the clamping action, the horizontal cylinder mechanism 17 first acts to move the film cutting assembly away from the film-pulling rod assembly for a distance, thereby exposing the end of the large bubble film material to a certain length, so as to facilitate the action of the pneumatic clamp 5 and clamp the end of the large bubble film material, thereby ensuring the accuracy of the feeding action.

[0032] In a preferred embodiment, as shown in the accompanying drawings, the film cutting assembly includes a second pressure rod mechanism disposed at the rear side of the cutter mechanism, the second pressure rod mechanism includes a second pressure rod 18 and a second vertical cylinder 19, and the second pressure rod 18 is driven to move up and down by the second vertical cylinder 19. Similarly, the second pressure rod 18 is provided to be used in the feeding process of the large bubble film material, when the large bubble film material reaches a set length, the second pressure rod 18 moves downward under the driving action of the second vertical cylinder 19 to press the large bubble film material, so as to prevent the large bubble film material from continuing to feed due to the inertia of the movement, thereby affecting the film cutting action of the cutter mechanism, and ensuring the cutting quality.

[0033] In this embodiment, a plurality of material guide rollers 20 are further provided on the outer side of the second pressure bar 18 relatively close to the coil support 2. The plurality of material guide rollers 20 are rotatably arranged and kept flush with the second pressure bar mechanism. Keeping flush here means that the upper side of the material guide roller 20 and the supporting surface of the second pressure bar mechanism are basically in a horizontal plane, so that the large bubble film material is basically in a horizontal state when feeding, avoiding wrinkles and ensuring the cutting quality.

[0034] Preferably, as shown in the accompanying drawings, a film cutting storage space 21 is formed below the film pulling rod assembly of the film pulling bracket 1, that is, the film pulling bracket 1 of this embodiment has a certain height space. After the large bubble film material is cut into sheets, the pneumatic clamp 5 is released, and the cut large bubble film sheets can fall automatically to the film cutting storage space 21 below to complete the unloading, and the film pulling rod assembly can move forward and reset by itself, thereby improving the operating film cutting efficiency of the large bubble film cutting device.

[0035] The above only describes the preferred embodiments of the utility model, which should not be construed as limiting the claims. The utility model is not limited to the above embodiments, and its specific structure is allowed to be changed. In short, all changes made within the protection scope of the independent claims of the utility model are within the protection scope of the utility model.
