Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packaging, in particular to a cigarette mold box with a self-cleaning device. Background Art

[0002] The cigarettes in the cigarette storage of the packaging machine host need to be sorted using cigarette mold boxes to facilitate transportation. During the transportation of the cigarette mold boxes, due to the directional operation and vibration of the belt, the tobacco at the end of the cigarettes is easy to fall out and get stuck in the cigarette mold box and the mold box pulley bracket. Some of the tobacco will gather in the corners of the mold box, affecting the filling of cigarettes. Another part of the fallen tobacco will gradually gather in the body cavity of the cigarette conveyor belt, affecting the positioning and transportation of the mold box. Since cigarette mold boxes are usually composed of multiple combinations, if a cigarette mold box is offset or damaged, it is necessary to replace it as a whole and adjust the position of each mold box and the relative position between the mold box and the transmission mechanism one by one, which greatly affects production efficiency. Manufacturers typically need to regularly clean tobacco from cigarette molds. For example, Chinese patent CN212172636U discloses an automatic cleaning device for the cigarette conveyor section of a ZB45 / ZB25 packaging machine. The device comprises a blowing air pressure inlet pipe, a blowing device, a cigarette dust collection device, a cigarette conveyor belt support, cigarette molds, a conveyor belt, a first cigarette dust delivery pipe, a negative pressure generator, a second cigarette dust delivery pipe, a cigarette dust filter, and an air pressure inlet pipe for the negative pressure generator. The blowing device and the cigarette dust collection device are positioned on opposite sides of the conveyor belt, with the cigarette molds positioned adjacent to the conveyor belt. The automatic cleaning device uses compressed air to lift tobacco dust accumulated between the conveyor belt and the pulleys. At the same time, the negative pressure generator creates a low-pressure zone at the high-pressure air level on the cigarette conveyor section of the packaging machine, drawing tobacco dust out of the cigarette conveyor section's body cavity. However, tobacco dust typically falls to the bottom of the cigarette molds. The blowing and suction positions directly affect the amount of tobacco dust released, which in turn affects operational stability.

[0003] Therefore, it is necessary for technical personnel in this field to provide a cigarette holder mold box with a self-cleaning device to provide targeted absorption for locations where cigarette butts are easily scattered, thereby reducing the scattering of cigarette butts and improving the stability of equipment use.

[0021] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0022] See also Figures 1 to 4The present invention provides a cigarette mold box with a self-cleaning device, comprising a cigarette box body 10. The cigarette box body 10 is in a U-shaped structure. An inner shell 11 is provided on the middle part of the bottom wall of the cigarette box body 10. The inner shell 11 divides the concave surface of the cigarette box body 10 into two cigarette box channels 12. Limiting plates 15 are symmetrically provided on the two opposite side walls of the cigarette box channels 12. When in use, multiple cigarettes in the cigarette storage of the packaging machine main body are neatly stuffed into the cigarette box channels 12. The limiting plates 15 are used to ensure that the cigarettes are stably placed in the cigarette box channels 12, thereby ensuring stability during transportation.

[0023] In this embodiment, the limiting plates 15 are made of plastic and are arranged at an angle in the cigarette box passage 12. The ends of the two limiting plates 15 that are closer to each other are closer to the bottom wall of the inner shell 11 than the ends of the two limiting plates 15 that are farther away from each other. This is to achieve compression of the cigarettes in the cigarette box passage 12.

[0024] Furthermore, the inner shell 11 is a square shell-like structure with a hollow interior. A dust suction duct 16 is provided within the inner shell 11. A dust suction port 17 is provided on the side wall of the inner shell 11 corresponding to the cigarette box passage 12. The dust suction port 17 is connected to the dust suction duct 16. A connecting port 14 is provided on the outer wall of the inner shell 11. One end of the connecting port 14 is connected to the dust suction passage 16, and the other end of the connecting port 14 is connected to a negative pressure pump (not shown). During use, the negative pressure pump is activated to create a negative pressure in the dust suction duct 16, thereby generating a negative pressure at the dust suction port 17. With the dust suction port 17 facing the cigarette box passage 12, cigarette dust and dust in the cigarette box passage 12 are absorbed, reducing the accumulation of cigarette dust and dust and preventing cigarette dust and dust from drifting to the transmission components, thereby improving the stability of the device.

[0025] It is understood that the negative pressure pump is a common commercially available micro-negative pressure pump, which refers to a micro air pump capable of generating negative pressure. Specifically, it has an inlet and outlet nozzle, an exhaust nozzle, and can continuously create a vacuum or negative pressure at the exhaust nozzle and a slight positive pressure at the exhaust nozzle. Its working medium is primarily gas, and it is a compact device. In this embodiment, the micro-negative pressure pump can be directly used, and the specific structure is not detailed here.

[0026] Furthermore, the dust suction port 17 is trumpet-shaped, and the outer opening of the dust suction port 17 abuts the bottom wall of the cigarette box channel 12. Since cigarette dust and dust are easily adsorbed on the wall of the cigarette box channel 12 during use, the height between the dust suction port 17 and the cigarette box channel 12 is reduced, so that the negative pressure generated at the dust suction port 17 can be closer to the cigarette dust and dust, thereby having a better absorption effect, thereby ensuring the stability of use of the utility model.

[0027] Furthermore, a cavity (not shown) is left between the dust collection duct 16 and the inner wall of the inner shell 11. The inner shell 11 also has air holes to reduce temperature differences and improve operational stability. The dust collection duct 16 is also detachably connected to the inner shell 11. This allows for quick replacement of any clogged dust collection duct 16 without disassembling the entire cigarette case or the transfer mechanism, further ensuring the stability and longevity of the present invention.

[0028] See also Figure 5 、 Figure 6 The connecting port 14 is provided on the wall of the inner shell 11 between the two cigarette box channels 12 , the cigarette is inserted from one end of the cigarette box channel 12 close to the connecting port 14 , and the filter of the cigarette is located at one end of the cigarette box channel 12 close to the connecting port 14 .

[0029] An inserting platform 19 is provided at one end of the inner housing 11, away from the connection port 14. An inserting hole 20 is provided within the inserting platform 19. The inserting hole 20 is perpendicularly disposed within the inserting platform 19 relative to the bottom wall of the cigarette box passage 12. The dust collection duct 16 is detachably connected to the inserting platform 19 and communicates with the inserting hole 20. An opening 13 is provided within the wall of the cigarette box body 10, away from the connection port 14. The opening 13 extends downward from the upper plane of the cigarette box passage 12, extending from one cigarette box passage 12 to the other, and passes through the inserting platform 19 to communicate with the inserting hole 20. During use, the end of the cigarette away from the filter is close to the opening 13, so as to ensure that the cigarette ends can enter the opening 13 or fall near the opening 13 after falling. The negative pressure pump is used to generate negative pressure near the opening 13 to absorb the fallen cigarette ends. At the same time, the opening 13 is opened at a position where the cigarette ends are likely to float and fall, thereby providing targeted absorption, reducing the dispersion of cigarette ends, and improving the service life of the utility model.

[0030] In this embodiment, the cross section of the opening 13 is an inverted T-shaped structure, and the width of the opening 13 inside the wall of the cigarette box body 10 is greater than the width of the opening 13 on the bottom wall surface of the cigarette box body 10, thereby ensuring that there is a stable negative pressure in the entire opening 13.

[0031] The specific operation method of the present invention is: start the negative pressure pump to create negative pressure in the dust suction pipe 16, thereby generating negative pressure at the dust suction port 17 and the opening 13, and utilizing the dust suction port 17 and the opening 13 to absorb cigarette dust and dust at the cigarette box channel 12 to complete the cleaning.

[0032] The utility model creates a negative pressure in the dust suction pipe 16 by starting the negative pressure pump, thereby generating negative pressure at the dust suction port 17 and the opening 13, and uses the dust suction port 17 to face the cigarette box channel 12 and the opening 13 close to the position where the cigarette dust is likely to float and fall, thereby providing targeted absorption, thereby achieving absorption of cigarette dust and dust in the cigarette box channel 12, reducing the accumulation of cigarette dust and dust, and preventing cigarette dust and dust from floating to the transmission components, thereby improving the stability and service life of the equipment.
