Description

Technical Field

[0001] The utility model relates to the technical field of packaging paper printing, in particular to a powder spraying device used for packaging paper printing. Background Art

[0002] Printing powder is an indispensable tool in offset printing. The printing powder sold on the market is mainly based on pure plant substances. Good powder particles are smooth, have excellent assimilation with ink, and are evenly distributed after spraying, which is of great help in improving printing quality and printing efficiency.

[0003] For example, a powder spraying device for packaging paper printing with the authorization announcement number "CN217622759U" is provided with a dual-axis motor, atomizing blades, spiral pieces, transmission rods and other components. Through the mutual cooperation between the dual-axis motor components and the transmission rod components, the output shaft components of the dual-axis motor can drive the spiral pieces through the rotation of the transmission rod, thereby achieving the effect that the device can drive the atomizing blades through the dual-axis motor, solving the problem of current powder spraying devices that are not uniform during powder spraying, causing local adhesion during packaging paper production, resulting in substandard packaging paper printing. However, the powder spraying device for packaging paper printing uses atomizing blades to make the dust evenly stick to the packaging paper. When the width of the packaging paper is narrow, the height of the atomizing blades is high and the spraying range is wide, causing some dust to fall on the conveyor belt, thereby increasing the work cost. At the same time, the powder spraying device for packaging paper printing has a fixed position of the atomizing blades. When the width of the packaging paper is wide, some areas on the surface of the packaging paper cannot be sprayed, requiring the operator to perform secondary processing, thereby reducing the work quality. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that dust is evenly adhered to packaging paper by atomizing blades.

At the same time, the powder spraying device for packaging paper printing has a fixed position of the atomizing blades. When the width of the packaging paper is wide, some areas on the surface of the packaging paper cannot be sprayed, and the operator needs to perform secondary processing, thereby reducing the work quality. A powder spraying device for packaging paper printing is proposed.

[0031] Working principle:

[0032] When the powder spraying device for packaging paper printing is used:

[0033] Preparation process:

[0034] Open the opening and closing plate 15, add a proper amount of material from the feed pipe 8 into the material box 4, and drop it onto the surface of the spiral blade.

[0035] Adjustment process:

[0036] When the wrapper is narrow:

[0037] Start the power supply of the first motor 502, and the output shaft of the first motor 502 rotates to drive the gear 503 to rotate, thereby driving the rack 504 to slide along the surface of the second fixed column 505, and at the same time, the protruding part of the rack 504 slides along the slide groove processed on the rocker arm 506, thereby driving the rocker arm 506 to swing, and the swing of the rocker arm 506 drives the lifting rod 507 to slide along the through hole processed on the first shell 501, and the lifting rod 507 moves downward to drive the material box 4 to move downward, thereby driving the fan blade 14 to move downward, and when the fan blade 14 beats the material into dust just to the edge of the packaging paper, turn off the power supply of the first motor 502 to ensure that a large amount of material dust does not fall on the surface of the conveyor belt 12, thereby reducing the working cost.

[0038] When the wrapping paper is wider:

[0039] Start the power supply of the second motor 902, the output shaft of the second motor 902 rotates to drive the worm 903 to rotate, thereby driving the worm wheel 904 to rotate, and the rotation of the worm wheel 904 drives the rotating rod 905 to make a circular motion, thereby driving the moving rod 906 to slide along the slide groove processed on the push rod 907, and at the same time, the push rod 907 slides along the through hole processed on the second shell 901, and the push rod 907 moves back and forth to drive the first shell to move back and forth 501, thereby driving the fan blades 14 to move back and forth. When the fan blades 14 move to the appropriate position, turn off the power supply of the second motor 902 to achieve a wider packaging paper surface bucket that can be sprayed with dust, and no secondary processing is required, thereby improving the work quality.

[0040] Powder spraying process

[0041] According to the width of the wrapping paper, adjust the position of the fan blade 14, start the power supply of the conveyor belt 12, put the wrapping paper on the conveyor belt 12, and the conveyor belt 12 drives the wrapping paper to move to the left. When the wrapping paper moves to the bottom of the fan blade, start the power supply of the double-headed motor 11. The output shaft of the double-headed motor 11 rotates and drives the spiral blade 10 and the fan blade 14 to rotate at the same time. The rotation of the spiral blade 10 drives the material to fall on the surface of the fan blade 14 along the surface of the motor box 2. The fan blade 14 breaks up the material and evenly falls on the narrower wrapping paper surface through the screen plate 13. At the same time, start the vacuum cleaner installed on the inner wall of the body 1 to collect the generated dust. The conveyor belt 12 transports the dust-sprayed wrapping paper from the left side of the body 1, and the operator collects it manually.
