Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a dust removal structure of packaging and printing equipment. Background Art

[0002] The dust removal device of packaging and printing equipment is usually used to remove dust from the outer surface of packaging box paper before printing. The design purpose of this dust removal device is to prevent the residual paper scraps and surface dust on the packaging box paper from polluting the inside of the printing machine, reduce the amount of dust accumulated inside the printing machine, and also ensure the printing effect; the dust removal device of packaging and printing equipment may include some key components, such as dust suction ports, fans, filters, etc.; the dust suction ports are used to capture dust and paper scraps on the surface of packaging box paper, and the fans provide the necessary suction to suck dust and paper scraps into the dust removal mechanism; the filters are used to separate dust and paper scraps to ensure that only clean air is discharged into the external environment.

[0003] In actual use, the dust removal devices of existing packaging and printing equipment are often manually cleaned by production personnel on a regular basis. However, since the filter absorbs a large amount of dust and paper scraps during operation, the air circulation rate in the dust bucket is reduced, which will continuously increase the workload of the drive motor, which is not conducive to the service life and safe production of the equipment. At the same time, the absorption of dust and paper scraps by the filter is an increasing process, and the suction force will be affected, thereby affecting the dust removal effect.

[0004] Therefore, the utility model provides a dust removal structure for packaging and printing equipment to solve the above problems. Utility Model Content

[0029] See also Figure 1 As shown, the purpose of this embodiment is to provide a dust removal structure for packaging and printing equipment, including a bracket 10, a dust removal bucket 20 and a dust suction bucket 30 and a dust removal mechanism arranged therein, a dust suction pipe 60 is arranged on the dust removal bucket 20, a driving motor 40 and an exhaust pipe 50 are arranged at the top of the dust suction bucket 30, a filter element 201 is arranged in the dust removal bucket 20, a transmission shaft 301 is arranged in the dust suction bucket 30, and a negative pressure fan 302 is arranged on the transmission shaft 301.

[0030] For further information, see Figure 2 and Figure 3 As shown, the outer sleeve of the filter element 201 is connected with a movable ring plate 205, on which bristles 206 are arranged, and a reciprocating screw 203 and a limiting rod 207 for limiting are arranged on the movable ring plate 205. A cover plate 202 is arranged at the top of the dust removal barrel 20, and an air suction port 305 is arranged on the cover plate 202. One end of the transmission shaft 301 is connected to the output shaft of the driving motor 40, and the other end is connected to the driving gear 303. The driving gear 303 is meshed with the driven gear 304. The driven gear 304 is arranged at the top of the reciprocating screw 203, and a sealed bearing 204 is arranged on the reciprocating screw 203; the driving motor 40 drives the transmission shaft 301 to rotate, thereby driving the negative pressure fan 302 and the driving gear 303 to rotate, and the driving gear 303 drives the driven gear 304 to rotate, thereby driving the rotation of the reciprocating screw 203.

[0031] For further information, see Figure 2 and Figure 3 As shown, the bottom ends of the limit rod 207 and the reciprocating screw 203 are fixedly mounted on the inner bottom surface of the dust removal barrel 20, the movable ring plate 205 is sleeved on the outside of the filter element 201, and is threadedly connected to the reciprocating screw 203, and is slidingly connected to the limit rod 207, the bristles 206 are fixedly mounted on the inner wall of the movable ring plate 205, the cover plate 202 is fixedly mounted on the top of the dust removal barrel 20, the air suction port 305 is fixedly mounted on the cover plate 202 and is connected thereto, the sealed bearing 204 is fixedly mounted on the cover plate 202, and the other end of the reciprocating screw 203 passes through the sealed bearing 204 and is fixedly connected to the driven gear 304; under the action of the limit rod 207, the movable ring plate 205 can only do up and down reciprocating motion on the reciprocating screw 203.

[0032] For details, see Figure 4 and Figure 5 As shown, the sealed bearing 204 includes a first annular groove 2031 and a rubber ring 2042. The first annular groove 2031 is opened on the inner wall of the sealed bearing 204. The reciprocating screw 203 is opened with a second annular groove 2041. The rubber ring 2042 is sleeved in the second annular groove 2041 on the reciprocating screw 203. The rubber ring 2042 is adapted to the first annular groove 2031 and the second annular groove 2041. The sealed bearing 204 and its matching first annular groove 2031, second annular groove 2041 and rubber ring 2042 further increase the airtightness to make the fan more efficient without affecting the rotation of the reciprocating screw 203.

[0033] In addition, see Figure 2 and Figure 3As shown, the negative pressure fan 302 is fixedly connected to the transmission shaft 301, and the transmission shaft 301 is fixedly connected to the driving gear 303, and the number of teeth of the driving gear 303 is much smaller than the number of teeth of the driven gear 304; since the number of teeth of the driving gear 303 is much smaller than the number of teeth of the driven gear 304, the driving gear 303 can not only drive the active driven gear 304 to rotate, but also ensure that the driven gear 304 does not rotate too fast, thereby realizing the periodic up and down movement of the movable exchange plate 205, and achieving the effect of efficient and fast cleaning of the filter element 201 without affecting the ventilation.

[0034] In addition, see Figure 2 As shown, the bristles 206 are made of a soft and wear-resistant material, and the bristles 206 extend into the interior of the filter element 201 but do not penetrate the filter element 201;.

[0035] The specific working principle is as follows:

[0036] The driving motor 40 drives the transmission shaft 301 to rotate, and then drives the negative pressure fan 302 and the driving gear 303 to rotate. The driving gear 303 drives the driven gear 304 to rotate, thereby driving the reciprocating screw rod 203 to rotate. Since the number of teeth of the driving gear 303 is much smaller than that of the driven gear 304, the driving gear 303 can not only drive the active driven gear 304 to rotate, but also ensure that the driven gear 304 does not rotate too fast; under the action of the limit rod 207, the movable ring plate 205 can only rotate the reciprocating screw rod 203. The movable ring plate 205 makes an up and down reciprocating motion on the reciprocating screw 203; the sealed bearing 204 and its matching first annular groove 2031, second annular groove 2041 and rubber ring 2042 further increase the airtightness to make the fan more efficient without affecting the rotation of the reciprocating screw 203, thereby realizing the periodic up and down movement of the movable exchange plate 205, thereby achieving the effect of efficient and fast cleaning of the filter element 201 without affecting ventilation, ultimately ensuring the service life of the equipment and safe production as well as long-lasting and efficient dust removal.
