Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a dust removal device for a vacuum packaging machine. Background Technique

[0002] In the prior art, vacuum packaging, also known as reduced-pressure packaging, is to evacuate and seal all the air in the packaging container, maintaining a highly reduced-pressure state inside the bag. The scarcity of air is equivalent to a low-oxygen effect, making it impossible for microorganisms to survive, so as to achieve the purpose of keeping food fresh and preventing spoilage. Applications include vacuum packaging in plastic bags, aluminum foil packaging, glassware, plastic and its composite materials packaging, etc.

[0003] After retrieval, a patent with the Chinese patent application number 202320332948.1 discloses a dust removal device for a vacuum packaging machine, which is applied to a portable vacuum packaging machine, including: a collection device arranged below the production line area of the portable vacuum packaging machine; a collection bin arranged below the collection device and communicated with the production line area of the portable vacuum packaging machine; wherein, the collection device is composed of two main boxes, which are arranged oppositely above the collection bin; the gap between different main boxes constitutes a material channel connecting the collection bin and the production line area of the portable vacuum packaging machine, and the vacuum adsorption device arranged inside the main box is communicated with the production line area of the portable vacuum packaging machine through a vacuum port arranged on the surface of the main box.

[0004] The above patent has the following deficiencies: This device timely guides the materials generated by the rupture of the packaging bag into the collection bin through the collection device, and synchronously drives the vacuum adsorption device to timely clean and collect the dust inside the portable vacuum packaging machine, reducing the formation of dust pollution in abnormal situations; however, in the actual use process, for the granular materials in vacuum packaging, this device sucks the materials and dust into the vacuum adsorption device through the vacuum port, and the fragments generated by the rupture of the packaging bag will also enter the device. The friction between the material particles will also cause the materials to generate dust, and the generated dust is mixed with the materials. When the packaging bag is damaged, the dust will directly fly in the air. Content of the Utility Model
