Description

Technical Field

[0001] This utility model relates to the field of cigarette pack film removal technology, and more specifically, it relates to an automatic blowing device with adjustable blowing direction to prevent film entanglement. Background Technology

[0002] In the tobacco processing industry, the automated dismantling of the cigarette pack film is a crucial step. Pneumatic clamps are widely used in this process due to their ease of operation and high clamping efficiency. Their main function is to dismantle the cigarette pack by gripping the film at the four corners, directly affecting the continuity and stability of subsequent tobacco sheet processing and playing a vital supporting role in the efficiency of the entire tobacco processing line. However, existing pneumatic clamps face the technical challenge of film entanglement in practical applications. When the clamp completes the gripping action and releases, irregular films easily become entangled on the clamp surface. This not only requires frequent machine shutdowns for manual cleaning and maintenance, disrupting the production process, but can also cause the clamp to jam, increasing the risk of equipment failure. Although some improvement solutions attempt to alleviate this problem by adjusting the clamping force or adding mechanical separation mechanisms, none of them fundamentally solve the inherent contradiction of film entanglement, and they are difficult to adapt to the characteristics of films with different thicknesses and toughnesses. Meanwhile, the instantaneous pressure difference adsorption effect between the film and the tobacco sheet is another prominent problem. During the process of disassembling the film using the fixture, a local pressure difference is formed at the moment of separation between the film and the tobacco sheet, causing some tobacco sheets to be adsorbed onto the film and detach with it, resulting in raw material loss. Existing technologies lack targeted control methods, making it impossible to eliminate the root cause of the pressure difference or effectively recover the adsorbed tobacco sheets. This not only reduces the utilization rate of raw materials but also increases the production costs for enterprises.

[0003] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes an automatic blowing device with adjustable blowing direction to prevent film wrapping. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic blowing device with adjustable blowing direction and anti-film wrapping.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic blowing device with adjustable blowing direction and anti-film entanglement, comprising a bracket, on which multiple clamps, cylinders, and air-lift rods are provided. The cylinders are used to drive the brackets to lift and lower. Every two brackets form a group. The brackets are provided with multi-pipe air distribution channels corresponding to the positions of each group of clamps. A cavity is opened in the multi-pipe air distribution channel, and the multi-pipe air distribution channel is connected to an air source through an air pipe. At least three universal nozzles communicating with the cavity are provided on the side of the multi-pipe air distribution channel facing the tobacco pack. The air-lift rods, cylinders, clamps, and air source are all connected to a controller.

[0006] Furthermore, the number of clamps is four, and the four clamps form a rectangle, corresponding to the four corners of the cigarette pack.

[0007] Furthermore, both ends of the multi-pipe gas distribution outlet are fixed to the bracket by snap fasteners.

[0008] Furthermore, the multi-pipe air distribution manifold is provided with multiple threaded holes, one of which is connected to an air pipe via a straight connector, at least three of which are connected to a universal nozzle, and the remaining threaded holes are blocked by a plug.

[0009] Furthermore, the jet direction of the omnidirectional nozzle is aligned with the film on the tobacco pack.

[0010] Furthermore, the multi-pipe gas distribution outlet is located in the middle of each set of clamps, and the multi-pipe gas distribution outlet is arranged parallel to a set of clamps.

[0011] Furthermore, when the threaded hole is connected to three universal nozzles, the three universal nozzles are respectively located at both ends and the middle of the multi-pipe air distribution manifold.

[0012] Furthermore, the gas pressure of the gas source is not less than 8 kg.

[0013] Furthermore, the omnidirectional nozzle has an angle adjustment range of no less than 45 degrees in any direction.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a dynamic airflow control system comprised of multi-pipe air distribution outlets and universal nozzles. Simultaneously, a forward airflow is ejected as the clamp grips the film, ensuring the film remains below the clamp and fundamentally preventing film entanglement when the clamp releases. This design reduces downtime for maintenance due to entanglement, lowers equipment failure rates, significantly improves the continuous operation capability of the production line, and simplifies the overall complexity of the device by eliminating the need for additional mechanical separation structures.

[0021] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0022] like Figures 1-4 As shown, this utility model provides an automatic blowing device with adjustable blowing direction to prevent film entanglement. Please refer to [link / reference]. Figure 1 The system includes a support 9, with clamps 5 on all four sides. Typically, there are four clamps 5 forming a rectangle, corresponding to the four corners of the cigarette pack 10. This allows the system to grip the film at each of the four corners of the cigarette pack 10, ensuring more even force distribution during film removal. A cylinder 8 is mounted on the support 9, positioned at its balance point for even force distribution. One end of the cylinder 8 is fixed to the operating device, enabling the support 9 to move up and down. When the cigarette pack 10 is transported below the support 9, the cylinder 8 drives the support 9 towards the cigarette pack 10. The support 9 also has a pneumatic rod 11. The pneumatic rod 11, cylinder 8, and clamps 5 are all connected to a controller. The cylinder 8 drives the support 9 towards the cigarette pack 10. When the pneumatic rod 11 contacts the surface of the cigarette pack 10, it sends a feedback signal to the controller, and the cylinder 8 stops lowering the cigarette pack 10. At this point, the controller controls the clamps 5 to grip the film on the cigarette pack 10.

[0023] like Figures 2-4 As shown, the clamps 5 on the bracket 9 are arranged in pairs. A multi-pipe gas distributor 1 is provided on the bracket 9 corresponding to the position of each pair of clamps 5. Both ends of the multi-pipe gas distributor 1 are fixed to the bracket 9 by clips 3. A cavity 12 is formed inside the multi-pipe gas distributor 1, and multiple threaded holes 13 communicating with the cavity 12 are formed on the multi-pipe gas distributor 1. One of the threaded holes 13 is connected to an air pipe 7 via a straight connector 4, and the other end of the air pipe 7 is connected to an air source. At least three of the threaded holes 13 are connected to universal nozzles 2. The threaded holes 13 connected to the universal nozzles 2 are located on the side of the multi-pipe gas distributor 1 facing the cigarette pack 10, and the other threaded holes 13 are blocked by the door. Thus, the air source delivers air into the cavity 12 through the air pipe 7 and sprays it out through the universal nozzle 2. The air jet direction of the universal nozzle 2 is aligned with the film, so that the air sprayed out by the universal nozzle 2 blows onto the film. Under the interference of the airflow, the film tends to move away from the clamp 5, thereby preventing the film from getting tangled on the clamp 5.

[0024] The multi-pipe air distribution outlet 1 is positioned in the middle of a set of clamps 5. The multi-pipe air distribution outlet 1 is arranged parallel to the set of clamps 5. This ensures that the membrane is subjected to uniform force when disturbed by airflow, and each part can be sprayed with air from the universal nozzle, preventing the membrane from being unevenly stressed on one side and getting tangled on the clamps 5.

[0025] When multiple universal nozzles 2 are provided, the universal nozzles 2 are evenly distributed on the multi-pipe air distribution row 1. This ensures that the membrane is subjected to uniform force when disturbed by airflow, and each part can be sprayed with air from the universal nozzles, preventing uneven force on one side of the membrane from causing it to wrap around the clamp 5. When there are three threaded holes 13 connected to the universal nozzles 2, the threaded holes 13 connected to the universal nozzles 2 are located at both ends and the middle position of the multi-pipe air distribution row 1.

[0026] It is worth noting that the air source is also connected to the controller, and the air source is equipped with an air pump. When the clamp 5 clamps the film on the smoke pack 10, the air is also simultaneously delivered to the multi-pipe air distribution outlet 1 through the air pipe 7, and sprayed onto the film through the universal nozzle.

[0027] It should be noted that the multi-pipe air distribution manifold 1 is equipped with redundant threaded holes 13 to accommodate different situations. Unused threaded holes 13 can be sealed with plugs 6. The omnidirectional nozzle 2 has an angle adjustment range of no less than 45 degrees in any direction, allowing for adjustment of the air jet direction of different omnidirectional nozzles 2 as needed.

[0028] The vertical distance between the multi-pipe air distribution row 11 and the clamp 55 is no more than 2 / 3 of the length of the multi-pipe air distribution row 11. This ensures the blowing effect of the universal nozzle 2. Exceeding this range will greatly weaken the airflow blown by the universal nozzle 2 onto the film, reducing the blowing effect.

[0029] First, the air source connected to the air pipe 7 has an air pressure of no less than 8 kg. During operation, the cylinder 88 on the support 99 extends downwards. When the air-pressing rod 1111 on the support 99 contacts the tobacco pack 1010 and triggers a signal, the clamp 55 immediately clamps the film. At the same time, the stainless steel universal nozzle 22 on the multi-pipe air distribution row 11 also blows air simultaneously, stopping when the clamp 55 is released. The entire process is automatic. During use, the angle of the stainless steel universal nozzle 22 can be adjusted according to the actual situation to ensure that the film remains below the clamp 55 under the air pressure. Furthermore, the positive air pressure blowing from the universal nozzle can eliminate the adsorption effect between the film and the tobacco sheet caused by the instantaneous pressure difference, blowing off the tobacco sheet adsorbed by the film and avoiding raw material loss.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
