Description

Technical Field

[0001] The utility model relates to a cleaning device for cigarette production equipment, in particular to a cigarette box top cover blowing device. Background Art

[0002] In the cigarette industry, cigarette boxes are often used to store tobacco. Empty cigarette boxes are transported to the packing station by conveyors. The automatic robot arm uses vacuum suction cups to remove the top cover, quantitatively load tobacco, and add the top cover before packing. After packing, the cigarette boxes are stored in the tobacco warehouse. Due to the dusty production environment of the packing station, dust easily accumulates on the box cover. When the automatic robot arm absorbs the top cover of the cigarette box, the dust on the top cover leads to a low success rate of absorption, and the suction cup inhaling too much dust can easily damage the components.

[0006] As a preferred embodiment of the above-mentioned purging device, the diameters of the multiple blowing holes on the blowing pipe gradually decrease from both ends to the center.

[0007] As a preferred embodiment of the above-mentioned purging device, the photoelectric switch is a diffuse reflection photoelectric switch.

[0008] As a preferred embodiment of the above-mentioned purging device, the diameter of the blowing hole is in the range of 1.0 mm to 3.0 mm.

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] The utility model provides a cigarette box top cover blowing device, which arranges a blowing unit above the conveying channel of each conveyor, relies on a photoelectric switch to detect whether there is a cigarette box, and uses this as a basis for controlling the on and off of the compressed air source of the blowing pipe, thereby effectively cleaning the dust and smoke foam on the surface of the cigarette box top cover, ensuring that the subsequent automated mechanical arm can stably adsorb the cigarette box top cover; and the blowing hole on the blowing pipe is located at the rear and lower part of the blowing pipe, and the blowing direction has a certain angle, ensuring that the cigarette box top cover is blown without dead ends, and ensuring the blowing effect.

[0015] The following is a detailed description of an embodiment of the utility model. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0016] See also Figures 1 to 3The present embodiment discloses a top cover purging device for a cigarette box 1. A plurality of conveyors connected in sequence are arranged at the exit side of the packing station. Each conveyor includes a conveying channel formed by a conveyor belt 2. The conveying direction of the conveying channel is from back to front. The purging device includes a plurality of purging units 3. The plurality of purging units 3 are arranged one by one above the conveying channels of the plurality of conveyors. Each purging unit 3 includes a photoelectric switch 4 and a blowing pipe 5. The photoelectric switch 4 and the blowing pipe 5 are respectively mounted on a frame 12 of the packing station and are arranged in sequence along the conveying direction. The photoelectric switch 4 is diffuse. Reflective photoelectric switch 4, photoelectric switch 4 is installed on the frame 12 of the packing station through a Z-shaped bracket 6, photoelectric switch 4 is installed with Z-shaped bracket 6 through two parallel nuts 7, and Z-shaped bracket 6 is installed on the frame 12 of the packing station by screw connection; the axial direction of the blowing pipe 5 extends along the width direction of the conveying channel, and a plurality of blowing holes 8 are opened at the rear lower part of the blowing pipe 5, and the blowing holes 8 are arranged in a row along the axial direction of the blowing pipe 5, and a connecting section 9 is provided in the middle section of the upper front part of the blowing pipe 5, and the connecting section 9 of the blowing pipe 5 is connected to the compressed air through the air pipe. The connecting section 9 of the blowing pipe 5 is installed on a connecting seat 10, and the connecting seat 10 is installed on the frame 12 of the packing station through an L-shaped bracket 11.

[0017] The diameter of the blowing hole 8 is in the range of 1.0 mm to 3.0 mm. The diameters of the multiple blowing holes 8 on the blowing pipe 5 gradually decrease from both ends to the center, and the diameters of the blowing holes 8 far away from the connecting section 9 are designed to be larger to balance the pressure of the compressed air, so that the pressure of the compressed air blown out from each blowing hole 8 is relatively even.

[0018] The working process of the top cover purge device of the smoke box 1 provided in this embodiment is as follows:
