Description

Technical Field

[0001] The utility model relates to the technical field of packaging products, in particular to a metal sheet printing dust removal device. Background Art

[0002] Metal packaging is widely used in many fields such as food, chemical industry, medicine, electronics, etc. Metal packaging refers to packaging containers made of metal sheets, usually made of aluminum sheets, stainless steel sheets, etc. Metal packaging has the characteristics of good barrier properties, impact resistance, and easy recycling. Metal packaging is usually printed with advertising words, patterns, etc. Generally, after printing on metal sheets, they are processed into packaging products such as metal boxes or metal cans.

[0003] Before printing, the metal sheet needs to be dusted to prevent dust particles from appearing on the printed surface of the metal sheet. Dust particles will cause spots on the surface of the printed metal packaging and the paint surface will be easily damaged. Utility Model Content

[0004] The utility model provides a metal sheet printing dust removal device, which can clean the dust on the surface of the metal sheet and at least solve part of the problems existing in the above-mentioned prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A dust removal device for metal plate printing comprises a conveyor belt and a fixed frame arranged above the conveyor belt, wherein a transverse plate is arranged on the fixed frame, a plurality of bristles are fixed on the transverse plate, and a driving mechanism for driving the transverse plate to move back and forth is arranged on the fixed frame; a dust suction pipe is arranged on the fixed frame, and a flat dust suction head is arranged at the end of the dust suction pipe, the flat dust suction head can make the suction force more concentrated, so as to facilitate the suction of dust brushed by the bristles, and a cleaning mechanism for cleaning the bristles is arranged above the bristles.

DETAILED DESCRIPTION

[0022] The following is a clear and complete description of the technical solutions in the implementation of the utility model in conjunction with the accompanying drawings. The described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments 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.

[0023] Example 1

[0024] like Figures 1 to 4 As shown, a metal plate printing dust removal device provided by Example 1 of the utility model includes a conveyor belt 1 and a fixed frame 2 fixed on the frames on both sides of the conveyor belt 1, and the fixed frame 2 is located above the conveyor belt 1. A first guide plate 19 is fixed on one side of the fixed frame 2, and a dust suction pipe 5 is fixed on the other side. Two parallel first vertical rods 20 are slidably mounted on the first guide plate 19, and a movable frame 7 is fixed at the bottom of the first vertical rod 20. A first screw rod 21 parallel to the first vertical rod 20 is rotatably mounted on the movable frame 7, and the first screw rod 21 is threadedly engaged with the first guide plate 19. In this way, when the first screw rod 21 is rotated, the first screw rod 21 can drive the movable frame 7 to move along the direction of the first vertical rod 20 under the action of the thread, thereby realizing the lifting and lowering of the movable frame 7.

[0025] Two sliding sleeves 8 are fixed on the movable frame 7, and the two sliding sleeves 8 are sleeved on the same guide rod 9. The two ends of the guide rod 9 are fixed with a horizontal plate 3 through a bracket. A plurality of bristles 4 arranged obliquely are fixed on the horizontal plate 3. The movable frame 7 is provided with a driving mechanism for driving the guide rod 9 to move back and forth on the sliding sleeve 8. When the driving mechanism drives the guide rod 9 to move back and forth, the bristles 4 can be brushed back and forth, and the bristles 4 can well sweep the dust on the metal sheet. Figure 2 and Figure 3 As shown, a flat dust suction head 6 is arranged beside the bristles 4, and the dust suction head 6 is connected to a dust suction pipe 5, and the dust suction pipe 5 is connected to a bag dust collector, so that the dust suction head 6 can suck away the dust brushed by the bristles 4 in real time to prevent the dust from falling on the metal sheet again. Considering that the bristles 4 may absorb some dust after being used for a period of time, a cleaning mechanism for cleaning the bristles 4 can be arranged above the bristles 4 to facilitate cleaning of the bristles 4. The cleaning mechanism can be a scraper.

[0026] In order to realize the reciprocating movement of the bristles 4, the driving mechanism designed in the utility model includes a motor 10 fixed on the movable frame 7 and an eccentric wheel 11 sleeved on the output shaft of the motor 10. When the motor 10 is started, the eccentric wheel 11 will rotate eccentrically. Two limit shafts 12 are fixed on the guide rod 9, and the eccentric wheel 11 is located between the two limit shafts 12. In this way, when the eccentric wheel 11 rotates, the eccentric wheel 11 can alternately push the two limit shafts 12 to move, realize the reciprocating movement of the guide rod 9, and finally enable the bristles 4 to reciprocate.

[0027] In order to reduce friction, rollers 13 are rotatably mounted on the two limiting shafts 12. In this way, the eccentric wheel 11 can alternately abut against the two rollers 13 to achieve the reciprocating movement of the guide rod 9, which has less loss of rolling friction than directly pushing the limiting shaft 12.

[0028] During use, the conveyor belt 1 drives the metal sheet to move. When the metal sheet moves under the bristles 4, the motor 10 drives the bristles 4 to move back and forth to clean the surface of the metal sheet. At this time, the dust suction head 6 absorbs the dust swept up by the bristles 4 in real time, thereby achieving dust removal before printing on the metal sheet and ensuring printing quality.

[0029] Example 2

[0030] On the basis of Example 1, in order to more conveniently clean the bristles 4, the utility model proposes Example 2. In this embodiment, the cleaning mechanism includes a second guide plate 16 fixed on one side of the sliding sleeve 8, a second vertical rod 17 slidably mounted on the second guide plate 16, and a cross bar 14 fixed at the bottom of the second vertical rod 17. A plurality of levers 15 are fixed at the bottom of the cross bar 14. A second screw rod 18 is rotatably mounted on the cross bar 14, and the second screw rod 18 is threadedly matched with the second guide plate 16. In this way, when the second screw rod 18 is rotated, the cross bar 14 can be driven to rise or fall. When the cross bar 14 falls to a certain extent, the lever 15 can contact the bristles 4. At this time, when the bristles 4 move back and forth, the lever 15 repeatedly collides with the bristles 4, thereby shaking off the dust on the bristles 4, and the shaken dust can be quickly sucked away by the dust collector 6. After cleaning the bristles 4, the cross bar 14 can be driven to rise, so that the lever 15 is separated from the bristles 4.
