Technical Field
[0001] The invention relates to the field of mechanical devices, and in particular to a powder auxiliary packaging device. Background Art
[0002] Powders are relatively fluffy and light in weight. During packaging and transportation, they take up a large space, which greatly increases the packaging and transportation costs of the powders, which needs to be solved urgently. Summary of the invention
[0003] In order to solve the above technical problems, the present invention provides a powder auxiliary packaging equipment, including: a cylinder, a filter, a negative pressure generator, an extrusion assembly, and an end plate. The two ends of the cylinder are respectively provided with a first opening and a second opening. The filter is a cylindrical structure, and the filter allows gas to pass through but does not allow powder to pass through. The filter is installed in the cylinder and is located between the first opening and the second opening and is coaxially arranged with the cylinder. The end plate is blocked at the first opening, and the inner wall of the end plate is sealed against one end of the filter. A feed port and an air intake port are provided on the end plate. One end of the air intake port is connected to the negative pressure generator, and the other end is connected to the gap between the filter and the cylinder. The extrusion assembly includes: a cylinder, a connecting rod, a pressure head, and a sealing cover. The cylinder is fixedly installed on the outer wall of the cylinder, and the sealing cover is sleeved on the outer wall of the cylinder near the second opening, and the sealing cover and the cylinder are movably sealed. The pressure head is matched and installed on the inner side of the filter and can slide relative to the inner wall of the filter. The pressure head is fixedly installed on the inner side of the sealing cover, and the connecting rod connects the cylinder piston and the sealing cover.
[0004] The filter includes: a mesh cylindrical hard outer frame, a filter layer, and a mesh cylindrical hard inner frame. The filter layer is provided with dense micropores that allow gas to pass through but do not allow powder to pass through. The filter layer matches and fits closely to the inner wall of the outer frame and the outer wall of the inner frame.
[0005] It also includes a hopper, a screw, and a motor. The discharge port of the hopper is connected to the feed port, and a screw matching the size of the feed port is arranged at the feed port. Part of the screw is located in the hopper, and part of the screw extends into the barrel through the feed port. The motor is fixed above the hopper and can drive the screw to rotate.
[0006] The present invention proposes that in the present invention, there are the following openings in the cylinder, namely, a first opening, a second opening, a feed port, and an air intake port. The first opening is blocked by an end plate, leaving the feed port and the air intake port. Among them, the feed port blocks the feed port during the process of the spiral rod spirally conveying the powder into the cylinder, and the air intake port is connected to the negative pressure generator, and the second opening is blocked by the pressure head. When the powder is continuously input into the cylinder, the negative pressure generator works at this time, and the air in the cylinder is extracted, thereby compressing the volume of the powder. At the same time, the pressure head further compacts the powder and further compresses the volume of the powder. The present invention can greatly compress the volume of the powder, and the packaging bag of the same capacity can hold more powder, thereby greatly reducing the packaging and transportation costs. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 It is a schematic diagram of the overall structure of the present invention. DETAILED DESCRIPTION

[0009] The present invention provides a powder auxiliary packaging device, comprising: a barrel 1, a filter 2, a negative pressure generator 3, an extrusion assembly 4, and an end plate 5. The barrel 1 has a first opening and a second opening at both ends, respectively. The filter 2 is a cylindrical structure, and the filter 2 allows gas to pass through but does not allow powder to pass through. The filter 2 is installed in the barrel 1 and is located between the first opening and the second opening and is coaxially arranged with the barrel 1. The end plate 5 is blocked at the first opening, and the inner wall of the end plate 5 is sealed against one end of the filter 2. A feed port and an air intake port are provided on the end plate 5, and one end of the air intake port is connected to the negative pressure generator. The other end of the filter 2 is connected to the gap between the cylinder 1 and the filter 2. The extrusion assembly 4 includes: a cylinder 41, a connecting rod (42), a pressure head (43), and a sealing cover 44. The cylinder 41 is fixedly mounted on the outer wall of the cylinder 1, and the sealing cover 44 is sleeved on the outer wall of the cylinder 1 near the second opening. The sealing cover 44 and the cylinder 1 are movably sealed. The pressure head 32 is matched and mounted on the inner side of the filter 2 and can slide relative to the inner wall of the filter 2. The pressure head (43) is fixedly mounted on the inner side of the sealing cover 44. The connecting rod (42) connects the piston of the cylinder 41 and the sealing cover 44. The filter 2 includes: a grid cylindrical hard outer frame 21, a filter layer 22, and a grid cylindrical hard inner frame 23. The filter layer 22 is distributed with dense micropores that allow gas to pass but do not allow powder to pass. The filter layer 22 matches and is tightly attached to the inner wall of the outer frame 21 and the outer wall of the inner frame 23. It also includes a hopper 6, a screw 7, and a motor 8. The discharge port of the hopper 6 is connected to the feed port, and a screw 7 matching the size of the feed port is arranged at the feed port. Part of the screw 7 is located in the hopper 7, and part of it extends into the barrel 1 through the feed port. The motor 8 is fixed above the hopper 6 and can drive the screw 7 to rotate.
[0010] In the present invention, the cylinder 1 has the following openings, namely, a first opening, a second opening, a feed port, and an air intake port. The first opening is blocked by the end plate 5, leaving the feed port and the air intake port. The feed port is blocked during the process of the spiral rod 7 spirally conveying the powder into the cylinder 1, and the air intake port is connected to the negative pressure generator 3, and the second opening is blocked by the pressure head 43. When the powder is continuously input into the cylinder 1, the negative pressure generator 3 works at this time, and the air in the cylinder 1 is extracted to compress the volume of the powder. At the same time, the pressure head 43 further compacts the powder and further compresses the volume of the powder. The present invention can greatly compress the volume of the powder, and the packaging bag of the same capacity can hold more powder, thereby greatly reducing the packaging and transportation costs.
