The carton paper is sucked by a paper suction wheel, and an air path with negative pressure air is provided inside the paper suction wheel. When the paper suction wheel is located at the paper storage position, the negative pressure air is kept unobstructed and the carton paper is sucked. When the paper suction wheel is located at the release position, the ventilation is disconnected to release the carton paper.

[0003] In order to ensure the smooth operation of the carton suction device, it is very important to design an effective negative pressure wind control mechanism.

[0004] However, such devices still have their limitations. The above suction control device has components such as sensors, relays and solenoid valves, which are complex in structure and have higher construction costs. In addition, the design of more electronic components makes the above device more susceptible to factors such as electromagnetic interference and temperature changes, making the overall system more prone to failure and having higher detection and maintenance costs.

[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides a negative pressure wind control mechanism for a paper suction wheel 1, such as Figure 1 and Figure 2As shown, the paper suction wheel 1 is arranged on the first rotating shaft 2, and the negative pressure wind control mechanism includes an air pipe assembly 5 for conveying negative pressure wind to the paper suction wheel 1; and also includes a control unit, the control unit includes a second rotating shaft 3 that rotates synchronously with the first rotating shaft 2, a trigger 6 arranged on the second rotating shaft 3, and a switch valve 4 for controlling the on and off of the negative pressure wind of the air pipe assembly 5, and the trigger 6 is connected in clutch with the switch valve 4. Among them, the synchronous rotation of the first rotating shaft 2 and the second rotating shaft 3 can be achieved by the same gear ratio transmission of the two. When in use, the trigger 6 realizes the switching state of the switch valve 4 by connecting in clutch with the switch valve 4. Since the second rotating shaft 3 rotates synchronously with the first rotating shaft 2, the frequency of the clutch connection between the trigger 6 and the switch valve 4 can correspond to the working state of the paper suction wheel 1. The above design has the advantages of simple structure, low cost and high stability. The system as a whole is not prone to failure, and the maintenance is simple and quick, which greatly reduces the downtime maintenance time caused by failure and improves the working efficiency of the paper suction wheel 1. To facilitate maintenance of the trigger member 6 , the trigger member 6 is preferably detachably connected to the second rotating shaft 3 .

[0029] In some embodiments, the trigger member 6 is a cam, and the protrusion 61 of the cam is connected to the switch valve 4 by a clutch. When in use, when the protrusion 61 is separated from the switch valve 4, the air path of the air pipe assembly 5 is opened, ensuring that the negative pressure wind of the suction wheel 1 is unobstructed to maintain its adsorption of the box paper; when the protrusion 61 is connected to the switch valve 4, the air path of the air pipe assembly 5 is closed, and the negative pressure wind of the suction wheel 1 is disconnected to release the box paper adsorbed on the suction wheel 1. In order to further improve the stability of the operation of the equipment, a plurality of through holes 62 for reducing the load are provided on the cam.

[0030] In some embodiments, in order to guide the gas flow, the air pipe assembly 5 includes an air inlet pipe 51, one end of which is connected to the switch valve 4, and the other end is connected to a negative pressure pump for providing negative pressure wind.

[0031] In some embodiments, the air pipe assembly 5 includes an air supply pipe 52, one end of which is connected to the switch valve 4, and the other end is connected to the paper suction wheel 1. The above two embodiments can be implemented in combination, and when in use, the on-off of the negative pressure wind between the air inlet pipe 51 and the air supply pipe 52 can be accurately controlled by controlling the on-off of the switch valve 4.

[0032] The utility model also provides a strip box suction device, comprising a paper suction wheel 1 and the above-mentioned negative pressure wind control mechanism for the paper suction wheel 1; the paper suction wheel 1 is arranged inside a box body 7 of the strip box suction device.

[0033] In some embodiments, the control unit is arranged outside the housing 7, which improves the convenience of adjusting the cam phase, makes maintenance more convenient and quick, and further shortens the debugging time.

[0034] In some embodiments, Figure 2As shown, an anti-interference gap area 8 is provided between the trigger member 6 and the box body 7 to ensure that the trigger member 6 will not collide or get stuck with the box body 7 when rotating, thereby extending the service life of the equipment and reducing maintenance costs.

[0035] In some embodiments, Figure 1 As shown, a fixing part 9 for fixing the air pipe assembly 5 is provided on the box body 7, which keeps the air pipe assembly 5 firmly installed and effectively plans and controls the air pipe wiring so as not to interfere with the operation of other components, thereby improving the overall reliability of the device.

[0036] In some specific embodiments, the working process of the negative pressure wind control mechanism for the paper suction wheel 1 is as follows:

[0037] The first rotating shaft 2 rotates synchronously with the second rotating shaft 3. When the paper suction wheel 1 sucks the strip of paper from the paper bank and conveys the strip of paper through the rotation of the first rotating shaft 2, the raised portion 61 of the trigger member 6 remains separated from the switch valve 4 to ensure that the negative pressure wind is unobstructed, so that the paper suction wheel 1 can stably absorb the strip of paper; when the paper suction wheel 1 reaches the release position of the strip of paper, the second rotating shaft 3 just drives the raised portion 61 to rotate to the position connected with the switch valve 4, the negative pressure wind in the air pipe assembly 5 is disconnected, and the paper suction wheel 1 releases the strip of paper.
