Description

Technical Field

[0001] The utility model relates to the field of powder packaging machines, in particular to a material unloading dust removal device for a powder packaging machine. Background Art

[0002] When the powder is packaged by the lapel packaging machine, the packaging bag is folded along the lapel former and guided to the outside of the film guide tube to form a barrel shape, and then falls to the bottom along the film guide tube to receive and package the powder in the guide tube;

[0003] Because it is powder packaging, when the powder goes down the guide tube to the barrel-shaped packaging bag, dust will be generated and spread outward along the gap between the film guide tube outlet and the packaging bag, and spread to the upper part of the lapel former to pollute the surrounding environment, which is easy to cause cross contamination and seriously affect the quality and safety of the powder product. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides a dust removal device for feeding a powder packaging machine.

[0006] A dust removal device for a powder packaging machine comprises a fixed frame, a film guide tube is arranged in the center of the fixed frame, a collar former is arranged on the outside of the film guide tube, a material guide tube is arranged in the center of the film guide tube, an adsorption device for treating dust inside the film guide tube is arranged on the upper part of the collar former, and a pressure regulating component is arranged on the upper part of the adsorption device.

[0007] Further optionally, the adsorption device includes an adsorption elbow connected and fixed to the film guiding tube, the top of the adsorption elbow is connected to an adsorption hose, and the outlet end of the adsorption hose is connected to the dust collector.

[0011] Compared with the existing technology, the beneficial effect of the utility model is as follows: the utility model provides an adsorption device and a pressure regulating component on the film guide tube of the powder packaging machine, so that the dust generated by the filling of the packaging bag at the lower part of the film guide tube is adsorbed by the material guide tube, thereby completely solving the dust hazard and ensuring the quality and safety of the powder product. At the same time, the negative pressure is adaptively adjusted for different packaging quantities to ensure that the dust is adsorbed and the material leakage caused by the large negative pressure is avoided.

[0013] Figure 2 yes Figure 1 Schematic diagram of the local structure in;

[0014] In the figure: a fixing frame 1, a material guide tube 2, a film guide tube 3, a lapel former 4, an adsorption elbow 5, an adsorption hose 6, an adjustment adsorption hole 7, and an adjustment sleeve 8. DETAILED DESCRIPTION

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0016] like Figure 1 As shown, a dust removal device for a powder packaging machine includes a fixed frame 1, a film guide tube 3 is arranged in the center of the fixed frame 1, a collar former 4 is arranged on the outside of the film guide tube 3, a material guide tube 2 is arranged in the center of the film guide tube 3, an adsorption device for treating dust inside the film guide tube 3 is arranged on the upper part of the collar former 4, and a pressure regulating component is arranged on the upper part of the adsorption device.

[0017] like Figure 1 , 2 As shown, the adsorption device includes an adsorption elbow 5 connected and fixed to the film guiding tube 3, the top of the adsorption elbow 5 is connected to an adsorption hose 6, and the outlet end of the adsorption hose 6 is connected to the dust collector.

[0018] like Figure 2 As shown, the pressure regulating component includes multiple rows of regulating adsorption holes 7 arranged on the film guide tube 3. The regulating adsorption holes 7 are equivalent to the role of balancing holes. They not only play a role in regulating pressure, but also can adsorb dust on the outside of the film guide tube 3. The film guide tube 3 is sleeved with an adjusting sleeve 8 that can move up and down.

[0019] like Figure 2 As shown, the adjustment sleeve 8 is configured by a flexible rubber sleeve, so that the adjustment sleeve 8 and the film guiding tube 3 have better fit.

[0020] like Figure 1 As shown, the connection between the adsorption elbow 5 and the film guide tube 3 is located at the center of the gap of the lapel former 4, so as to ensure the effect of dust absorption and avoid drying of the packaging bag through the lapel former 4. At the same time, the adsorption elbow 5 is also away from the packaging bag at the bottom of the film guide tube 3, so as to reduce the adsorption force on the inside of the packaging bag and avoid the leakage of powder.

[0021] The implementation principle of a dust removal device for a powder packaging machine in the embodiment of the present application is as follows:

[0022] When the powder material falls down the guide tube and generates dust for packaging, the vacuum cleaner connected to the adsorption hose 6 is started. The vacuum cleaner forms a negative pressure inside the film guide tube 3 through the adsorption hose 6 and the adsorption elbow 5, and the dust generated by the material guide tube 2 loading the packaging bag at the bottom of the film guide tube 3 is adsorbed, thus completely solving the dust hidden danger and ensuring the quality and safety of the powder product.

[0023] In order to adapt to the different dust concentrations generated by different packaging quantities, the pressure regulating component can be used for adjustment. When a large amount of packaging generates more dust, it is necessary to increase the negative pressure in the film guide tube 3. The regulating sleeve 8 of the pressure regulating component can be moved to block multiple rows of regulating adsorption holes 7 (different rows of regulating adsorption holes 7 can be blocked according to the site), reduce the pressure relief in the film guide tube 3, and thus increase the negative pressure in the film guide tube 3; when a small amount of packaging generates less dust, the negative pressure in the film guide tube 3 can be reduced, and the regulating sleeve 8 can be moved in the reverse direction to open the regulating adsorption holes 7, increase the pressure relief in the film guide tube 3, and thus reduce the negative pressure in the film guide tube 3. Under the condition of ensuring the adsorption of dust, the powder in the packaging bag can be prevented from being adsorbed and running due to the higher negative pressure;

[0024] The opened regulating adsorption holes 7 can adsorb the dust previously accumulated on the upper part of the lapel former 4 , thereby reducing the dust pollution on the outer side of the film guide tube 3 .

[0025] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
