Abstract
Description
Technical Field
[0001] The utility model relates to powder packaging, conveying and cleaning equipment, in particular to a powder air blowing and cleaning device. Background Art
[0002] In the prior art of powder packaging production, powder will adhere to the packaging bag and needs to be cleaned manually. Manual cleaning is difficult, labor-intensive and has a bad working environment.
[0003] Since the powder packaging bags are irregular, the effect of ordinary brush cleaning is not obvious. After brush cleaning, powder is still attached to the surface of the packaging bags, which seriously affects the appearance of the packaging bags. Utility Model Content
[0004] In order to solve the deficiencies of the prior art, the utility model proposes a powder air blowing cleaning device.
[0005] The powder air blowing cleaning device capable of solving the problems of the prior art includes an air blowing mechanism, the difference being that:
[0006] 1. The air blowing mechanism includes an air blowing knife arranged based on an air blowing bracket.
[0007] 2. The air blowing support is arranged on the conveying path of the powder bag from front to back.
[0008] 3. Multiple air-blowing knives are hung side by side on the left and right beams of the air-blowing bracket. Each air-blowing knife has a knife body that is bent backward so that the air-blowing port at the bottom blows air forward and downward in the direction of travel of the powder bag.
[0009] 4. The side-by-side width of multiple air knives is equal to the width of the powder bag.
[0010] Furthermore, left and right righting arms are provided to straighten the powder bag. The left and right right righting arms flush with the powder bag are respectively hinged on the left and right rear extension frames and tilted inwardly under the action of left and right return springs. The left and right rear extension frames are installed on the left and right vertical beams of the air blowing bracket. Rollers are installed at the rear end of each righting arm, and the distance between the left and right rollers is smaller than the side-by-side width of multiple air blowing knives.
[0011] Furthermore, in order to remove the powder on the side of the powder bag, each straightening arm is provided with an air blowing pipe, and the blowing port of each air blowing pipe is located beside the corresponding roller.
[0012] Beneficial effects of the utility model:
[0013] 1. The utility model adopts the structure of the powder air blowing cleaning device, which adopts the combined use of the air blowing knife and the straightening arm (with an air blowing tube). Regardless of whether the surface of the powder bag is regular or not, the powder attached to the surface of the powder bag can be completely removed, and the cleaning effect is obvious.
[0014] 2. The utility model adopts air-blowing knife and air-blowing tube to spray the powder bag forcefully, without any contact in the whole process, thus no wear will be caused to the powder packaging bag. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of the utility model is further described below in conjunction with the implementation modes shown in the accompanying drawings.
[0020] The utility model comprises an air-blowing knife 2 arranged based on an air-blowing bracket 4 .
[0021] The air blowing support 4 is arranged on the conveying path of the powder bag 1, and the powder bag 1 is conveyed from front to back through the conveyor belt. The air blowing support 4 is a gantry frame, including left and right cross beams at the top (located above the conveyor belt) and left and right vertical beams supporting the cross beams. The left and right vertical beams are installed on the left and right machine bases on the left and right sides of the conveyor belt. The upper and lower rear extension frames 6 are installed on the front end surface of each vertical beam. The upper and lower rear extension frames 6 are located on the side of the powder bag 1, such as Figure 1 , Figure 2 , Figure 3 shown.
[0022] Five air blowing knives 2 are arranged side by side in the left and right directions, and the side-by-side width of the five air blowing knives 2 is aligned with the width of the powder bag 1. Each air blowing knife 2 includes an upper and a lower knife body bent backwards, and the upper knife body tilted backwards and downwards is suspended on the beam through a hinge structure, and the blowing port at the lower end of the lower knife body tilted forwards and downwards can blow air in the direction of travel of the powder bag, such as Figure 1 , Figure 2 , Figure 3 shown.
[0023] Four righting arms 3 are respectively installed on the upper, lower, left and right rear extension frames 6. The specific installation method is: each righting arm 3 is installed on the rear extension frame 6 through inner and outer hinges and folding plate springs 5. The folding plate springs 5 rotate the corresponding righting arm 3 inward and return it obliquely. A roller 7 is installed at the rear end of each righting arm 3. In the return position, the rollers 7 on the left and right right righting arms 3 at the upper and lower positions are directly in front of the five air blowing knives 2 and the distance between the left and right rollers 7 is less than the side-by-side width of the five air blowing knives 2. The left and right rollers 7 at the upper and lower positions are located on the left and right sides of the powder bag 1; each righting arm 3 is provided with an air blowing pipe, and the blowing port of each air blowing pipe is located beside the corresponding roller 7, such as Figure 1 , Figure 2 , Figure 3 shown.
[0024] The operation mode of the utility model is:
[0025] 1. The powder bag 1 is transported to the air blowing support 4 on the conveyor belt.
[0026] 2. The five air blowing knives 2 and the four air blowing pipes are started at the same time and are in the blowing mode.
[0027] 3. When the powder bag 1 passes through the air blowing bracket 4, five air blowing knives 2 simultaneously blow powder to the top surface of the powder bag 1 toward the front and bottom.
[0028] 4. During the top surface powder blowing operation, the front end of the powder bag 1 reaches the working area of the left and right straightening arms 3, and the front end surface of the powder bag 1 pushes the left and right straightening arms 3 to the left and right sides so that the left and right rollers 7 roll against the left and right sides of the powder bag 1. The powder bag 1 continues to move forward, and the left and right straightening arms 3 can center the tilted powder bag 1. At the same time, the four air blowing tubes blow powder on the left and right sides of the powder bag 1.
[0029] 5. After the powder bag 1 completely passes through the air blowing bracket 4, the powder attached to the top surface and the left and right sides of the powder bag 1 is cleaned.
