Description

Technical Field

[0001] This utility model relates to the printing field, specifically to an air suction cleaning device. Background Technology

[0002] Plastic packaging bags are bags made from plastic and used in the production of various daily necessities, widely used in both daily life and industrial production. After printing and hot pressing, the packaging bags, as described in publication number "CN222181439U", are typically wound up and stored by rollers, awaiting shipment to the corresponding manufacturer for slitting and filling. During the production and winding process, static electricity inevitably accumulates on the bag surface. Fine particles such as hair shed by employees around the production line are easily attracted to the bags due to static electricity, affecting the product's appearance and quality. For products requiring cleanliness and sterility, this contamination can lead to product defects. Removing hair and other particles from the packaging bags requires manual inspection and additional cleaning, significantly reducing production efficiency and thus necessitating a solution. Utility Model Content

[0003] To avoid and overcome the technical problems existing in the prior art, this utility model provides an air suction cleaning device. This utility model realizes automatic air suction cleaning of particulate matter on the surface of packaging bags.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A suction cleaning device is provided in which a packaging bag is wound up by a take-up roller via a conveyor roller. A cleaning chamber is provided between the conveyor roller and the take-up roller. A cleaning tube is provided in the cleaning chamber on the upper and lower sides of the packaging bag. The axes of the two cleaning tubes are arranged parallel to the axis of the take-up roller. The two cleaning tubes are driven by a lifting cylinder to produce a vertical lifting action. An air suction hole is opened on the side of the packaging bag adjacent to the two cleaning tubes. The pressure inside the cleaning tube is lower than the pressure outside the cleaning tube.

[0006] As a further embodiment of this utility model: the cleaning tube includes an outer sleeve and an inner sleeve arranged coaxially, the cavity of the inner sleeve being connected to the fan; there is an annular gap between the outer sleeve and the inner sleeve to allow airflow to pass through, the air intake includes an outer air intake hole opened on the outer sleeve and an inner air intake hole opened on the inner sleeve, both the outer air intake hole and the inner air intake hole are arranged parallel to the axis of the take-up roller, and the outer air intake hole and the inner air intake hole are staggered along the circumference of the cleaning tube, and a filter screen is provided between the outer air intake hole and the inner air intake hole.

[0007] As a further embodiment of this utility model: a filter sleeve is coaxially sleeved outside the inner sleeve and rotates with the inner sleeve. The filter sleeve includes partition strips evenly spaced around the circumference of the inner sleeve. A guide gap is formed between adjacent partition strips to allow airflow to pass through. The width of the guide gap is greater than the width of the inner air intake hole. A filter screen is provided on each partition strip along the radial direction of the inner sleeve.

[0008] As a further improvement of this utility model: the lengths of the outer sleeve and the inner sleeve correspond, and the openings at both ends are closed by cover plates to form a sealed cleaning tube. A set of cover plates is provided with a rotating ring that rotates coaxially, and each separator is inserted and fixed on the rotating ring.

[0009] As a further improvement of this utility model, each filter screen is inserted and positioned in conjunction with the separator strip.

[0010] As a further improvement of this invention, the surface of the filter screen is coated with adhesive.

[0011] As a further improvement of this utility model, the phase difference between the external air intake and the internal air intake does not exceed thirty degrees.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. After the fan of this utility model is started, the inner sleeve enters a negative pressure state. Most of the airflow passes through the external suction port, the filter screen between the external suction port and the internal suction port, and then is discharged by the fan. At the same time as suction, hair and other adsorbed substances on the surface of the packaging bag enter the cleaning tube and are intercepted by the filter screen, thereby realizing the suction cleaning operation of the packaging bag.

[0014] 2. After a long period of cleaning operation, the unfiltered screen on the filter sleeve can be rotated between the outer and inner air intake holes by rotating the rotating ring, so that the filter sleeve can be cleaned online for a long time and avoid frequent shutdowns to replace the screen.

[0015] 3. The filter screen of this utility model is coated with adhesive, which facilitates the adhesion of hair and other debris. The filter screen can be detachably fixed to each separator strip through plug-in connection, making it easy to replace and clean.

[0016] 4. This utility model uses a cylinder to lift the cleaning tube to adjust the distance between the cleaning tube and the packaging bag, so as to achieve the best suction effect; the detachable design of the cleaning tube makes it easy to install and replace. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-3 In this embodiment of the invention, an air-suction cleaning device is provided. Uncut continuous packaging bags are wound by a take-up roller 3 via a conveyor roller 1. A cleaning chamber 2 is provided between the conveyor roller 1 and the take-up roller 3. The cleaning chamber 2 is open at both ends and contains two sets of cleaning pipes 5. The two sets of cleaning pipes 5 are arranged parallel to each other, with their axes parallel to the axis of the take-up roller 3, and are symmetrically arranged vertically. Lifting cylinders 4 are installed at the top and bottom of the cleaning chamber 2. The lifting cylinders 4 are connected to the cleaning pipes 5 via pins or positioning rings, driving the cleaning pipes 5 to rise and fall, thereby adjusting the distance between the cleaning pipes 5 and the conveyed packaging bags. The length of the two sets of cleaning pipes 5 is slightly greater than the width of the packaging bags.

[0027] The cleaning tube 5 includes an outer tube 51 and an inner tube 53 arranged coaxially. The openings at the ends of the outer tube 51 and the inner tube 53 are closed by two sets of cover plates 54. An external air suction hole 511 is provided on one side of the outer tube 51 adjacent to the packaging bag along the length of the tube. The distance between the external air suction hole 511 and the packaging bag is preferably no more than 1 cm.

[0028] An inner suction hole 531 is provided along the length of the inner sleeve 53. Both the inner suction hole 531 and the outer suction hole 511 are arranged parallel to the axis of the take-up roller 3. There is an angle between the inner suction hole 531, the outer suction hole 511 and the axis of the inner sleeve 53. This angle is preferably no more than 30 degrees, so that the inner suction hole 531 and the outer suction hole 511 are staggered in circumferential direction and arranged adjacent to each other. A fan 56 is installed on one set of cover plates 54. The air inlet of the fan 56 is coaxially arranged with the cavity of the inner sleeve 53.

[0029] Another set of cover plates 54 is coaxially provided with a rotating ring 55 that rotates in conjunction with the cover plate 54. The rotating ring 55 has evenly spaced arc-shaped dividing strips 521 along its circumference. Each dividing strip 521 is arranged in close contact with the outer wall of the inner sleeve 53, and the dividing strips 521 cooperate to form a filter sleeve 52 fitted around the outer ring of the inner sleeve 53. A guide gap 522 is formed between adjacent dividing strips 521, and the width of the guide gap 522 is greater than the width of the inner suction hole 531. In operation, one set of guide gaps 522 always corresponds to the position of the inner suction hole 531, thus allowing gas to pass through.

[0030] Each separator 521 is radially equipped with a filter screen 523, the size of which corresponds to the spacing between the outer sleeve 51 and the inner sleeve 53. After the fan starts, the inner sleeve 53 enters a negative pressure state, and most of the airflow passes sequentially through the outer suction port 511, the filter screen 523 between the outer suction port 511 and the inner suction port 531, and then through the inner suction port 531 before being discharged by the fan 56. Simultaneously, hair and other adsorbed matter on the surface of the packaging bag enter the cleaning pipe 5 and are intercepted by the filter screen 523, thus achieving the suction cleaning operation of the packaging bag.

[0031] To improve adsorption efficiency, the surface of filter screen 523 is coated with adhesive, making it easy to adhere to hair and other debris. Filter screen 523 can be detachably fixed to each separator strip 521 through a plug-in connection, facilitating replacement and cleaning.

[0032] After a long cleaning operation, the unfiltered screen 523 on the filter sleeve 52 can be rotated between the outer air intake 511 and the inner air intake 531 by rotating the rotating ring 55, so that the filter sleeve 52 can achieve long-term online cleaning operation.
