Description

Technical Field

[0001] This utility model belongs to the field of tobacco technology, specifically relating to a box-turning device with automatic blowing function. Background Technology

[0002] After the vacuum rehumidification process in the cigarette-making workshop, the tobacco leaves typically need to be turned over before being sent to subsequent production stages. However, existing turning machines often leave some tobacco leaves inside the cigarette box after each turn. These residual tobacco leaves need to be manually cleaned by operators using compressed air. Generally, operators need to stand on a platform at a height of over 3 meters and hold the compressed air hose to clean them (e.g., Figure 1 As shown, the operator needs to stand at platform A and use a compressed air hose to clean the tobacco boxes inside the turning machine. This manual cleaning method is not only time-consuming and labor-intensive, seriously affecting production efficiency, but also requires the operator to work at height, which is prone to accidents and poses significant safety hazards. Therefore, there is an urgent need for a device that can automatically clean the tobacco residue inside the tobacco boxes, reducing reliance on manual labor and lowering operational risks.

[0003] This utility model is proposed for this purpose. Utility Model Content

[0004] This invention provides a box-turning device with automatic blowing function. Through controller operation, the box-turning machine and the feeder work in tandem, achieving intelligent control of automatic blowing and cleaning of tobacco, significantly improving the automation level and safety of tobacco processing workshops.

[0005] The technical solution of this utility model is as follows:

[0006] A box-turning device with automatic blowing function includes: a box-turning machine 1 and a feeder 2; a compressed air pipe 20 is fixedly arranged on each of the two side walls of the feeder 2, and the pipe opening 203 of the compressed air pipe 20 is aligned with the bottom of the smoke box inside the box-turning machine 1; the compressed air pipe 20 is connected to an external compressor; the connection between the box-turning machine 1 and the feeder 2 is a hinge 3.

[0007] Preferably, each compressed air pipe 20 has two fixing points on the side wall of the feeder 2. The first fixing point 201 is located in the middle of the side wall of the feeder 2, and the second fixing point 202 is located at the upper end of the side wall of the feeder 2 at the lower end of the opening of the box turning machine 1.

[0008] Preferably, a solenoid valve 204 is provided at the lower part of the pipe opening 203 of each compressed air pipe 20; the pipe openings 203 of the two compressed air pipes 20 are cross-aligned with the bottom of the smoke box inside the box-turning machine 1.

[0009] Preferably, photoelectric sensors 21 are arranged on the inner walls of both sides of the feeder 2 relative to the opening of the box-turning machine 1; and a conveyor belt 22 is located at the bottom of the feeder 2.

[0010] Preferably, it further includes a control device 4; the control device 4 includes: a controller 40 and a display 41 electrically connected to the controller 40; the control device 4 is electrically connected to the photoelectric sensor 21, two solenoid valves 204 and the box-turning machine 1; the controller 40 can be a PLC control system, and the display 41 is an operator terminal for technicians.

[0011] The overall operation of the automatic blowing box-turning device of this utility model is as follows:

[0012] The device is powered on and initialized, and the parameters are set before entering standby mode. When the photoelectric sensor 21 detects that there are no tobacco leaves in the feeder (i.e., when the material is fed into the next processing stage by the conveyor belt 22 at the bottom of the feeder 2), it sends a signal to the controller 40. Under the control of the controller 40, the tilting machine 1 is started to tilt, pouring the tobacco leaves in the tobacco box inside the tilting machine 1 into the feeder 2. After the material is poured out, the tilting machine 1 maintains the tilting position as follows: Figure 2 As shown; at this time, the photoelectric sensor 21 detects that the feeder 2 is full of tobacco leaves and sends a signal to the controller 40. Under the control of the controller 40, two solenoid valves 204 are opened, the compressed air pipeline 20 is opened, and the pipeline port 203 is cross-aimed at the bottom of the tobacco box in the tipper 1 for blowing. After the blowing action is delayed for a set time (such as 20 seconds), the two solenoid valves 204 are closed under the control of the controller 40, completing the cleaning of the bottom of the tobacco box in the tipper 1. Cross-aiming at the bottom of the tobacco box in the tipper 1 has a better blowing effect and can clean the bottom of the tobacco box in the tipper 1 more thoroughly. Then the tipper 1 lowers the tobacco box and waits for the next tobacco box to arrive; a new round of tipping, dumping and cleaning process begins.

[0013] The above steps are performed continuously and automatically. After each box-turning operation, the solenoid valve 204 is automatically activated to perform a blowing cleaning, removing any remaining tobacco material from the tobacco box inside the box-turning machine 1. The parameters for the above steps can be input on the display 41, and the overall operation process can be displayed on the display 41.

[0014] The beneficial effects of this utility model are:

[0015] This utility model's automatic blowing and turning device, under the control of the control device 4, links all components together to achieve automated control of each stage, including turning, inspection, and blowing cleaning. This improves the automation level and safety of the tobacco processing workshop, increases cleaning efficiency, reduces labor costs, ensures production continuity, effectively reduces the impact of tobacco residue on product quality, ensures product consistency and reliability, and improves product quality; at the same time, it extends the lifespan of the entire device.

[0026] like Figures 1-4 As shown, the present invention provides a box-turning device with automatic blowing function, which includes: a box-turning machine 1 and a feeder 2; a compressed air pipe 20 is fixedly arranged on each of the two side walls of the feeder 2, and the pipe opening 203 of the compressed air pipe 20 is aligned with the bottom of the smoke box inside the box-turning machine 1; the compressed air pipe 20 is connected to an external compressor; the connection between the box-turning machine 1 and the feeder 2 is a hinge 3.

[0031] The overall operation mode of the automatic blowing box-turning device of this utility model is as follows:

[0032] The device is powered on and initialized, and the parameters are set before entering standby mode. When the photoelectric sensor 21 detects that there are no tobacco leaves in the feeder (i.e., when the material is fed into the next processing stage by the conveyor belt 22 at the bottom of the feeder 2), it sends a signal to the controller 40. Under the control of the controller 40, the tilting machine 1 is started to tilt, pouring the tobacco leaves in the tobacco box inside the tilting machine 1 into the feeder 2. After the material is poured out, the tilting machine 1 maintains the tilting position as follows: Figure 2 As shown; at this time, the photoelectric sensor 21 detects that the feeder 2 is full of tobacco leaves and sends a signal to the controller 40. Under the control of the controller 40, two solenoid valves 204 are opened, the compressed air pipeline 20 is opened, and the pipeline port 203 is cross-aimed at the bottom of the tobacco box in the tipper 1 for blowing. After the blowing action is delayed for a set time (such as 20 seconds), the two solenoid valves 204 are closed under the control of the controller 40, completing the cleaning of the bottom of the tobacco box in the tipper 1. Cross-aiming at the bottom of the tobacco box in the tipper 1 has a better blowing effect and can clean the bottom of the tobacco box in the tipper 1 more thoroughly. Then the tipper 1 lowers the tobacco box and waits for the next tobacco box to arrive; a new round of tipping, dumping and cleaning process begins.

[0033] The above steps are performed continuously and automatically. After each box-turning operation by the box-turning machine 1, the solenoid valve 204 is automatically activated to perform a cleaning process, removing any remaining tobacco leaves from the tobacco box inside the box-turning machine 1. The parameters for these steps can be input on the display 41, and the overall operation process can be displayed on the display 41.
