Description

Technical Field

[0001] The present invention belongs to the technical field of material packaging equipment, and relates to a heat-sealing machine for material packaging bags. Background Art

[0002] With the continuous development and technological progress of the product material packaging industry, the technical requirements for material packaging machinery and equipment, including the heat-sealing machine for material packaging bags, are also getting higher and higher, because it is directly related to the packaging effect and quality of the packaged products. In the known technology, the heat-sealing machine for material packaging bags applied in the existing industrial and agricultural production mainly consists of a heat-sealing machine body, an input mechanism, a heat-sealing bag mouth mechanism, a removal mechanism, etc. However, limited by the structure of the heat-sealing machine for packaging bags, due to the fixed body structure of the whole machine, the heat-sealing operation of the packaging bags used in the multi-functional automatic large-bag material packaging production line is restricted, and the actual application is relatively inconvenient; for another example, the Chinese patent application publication number CN 113306794A discloses a technical solution of "a ton-bag compaction and filling system for processing wet-stored fermented corn". An air-extracting heat-sealing machine is provided outside the packaging machine described in it, and a conveyor is provided between the air-extracting heat-sealing machine and the vibrating device. The ton-bag on the vibrating panel is horizontally conveyed to the air-extracting heat-sealing machine by the conveyor, and the bag mouth of the ton-bag is manually placed on the air-extracting heat-sealing machine for vacuum extraction and heat-sealing. It solves the problem that the wet-stored fermented corn processing equipment in the prior art cannot store low-moisture corn flour. However, for the air-extracting and heat-sealing machine among them, the bag mouth of the ton-bag needs to be manually placed on the air-extracting heat-sealing machine, and it can be inferred that further improvement is required for the heat-sealing operation of the packaging bags actually used in the multi-functional automatic large-bag material packaging production line.

[0013] When the present invention is in use, according to the design requirements and actual needs, the movable air extraction and heat sealing machine in the multi-functional automatic large-bag material packaging production line of the present invention application is correspondingly docked and assembled into the multi-functional automatic large-bag material packaging production line. The front is connected to the weighing and bagging machine, and the rear is connected to the packaging bag product conveyor or the machinery for conveying and loading into containers, etc. The programmable industrial control computer is connected to the total electrical controller in the entire production line.

During the operation, the programmable industrial control computer is used to set the indicators of air extraction, heat sealing and bagging. After the operation starts, after the material is weighed and bagged, the packaging bag enters the guiding mechanism of the movable air extraction and heat sealing machine of the present application, clamps the bag mouth to ensure the flatness of the bag mouth, and is automatically sent to the air extraction and heat sealing mechanism. The air extraction and heat sealing mechanism opens the bag mouth of the packaging bag and inserts the air extraction pipe.

After air extraction, the packaging bag is sealed synchronously by the electric heating method of the electric heating sheet. The brass guide post presses against the inner side edge of the heating sheet, so that the heating sheet is always in a straightened state. The first heat sealing cylinder pushes forward and the rear heating plate extends. When the first heat sealing cylinder retracts, the compression spring sleeve makes the rear heating plate return to its position.

Then, the servo motor in the transverse movement mechanism drives the synchronous belt to drive the air extraction and heat sealing mechanism to move reciprocally. The function of the frame-type lifting mechanism is: according to the actual operation needs, by rotating the hand crank, the worm gear is engaged with the worm to realize the moving function between the sprocket and the chain, so as to drive the up and down movement and adjustment positioning of the air extraction and heat sealing mechanism, the transverse movement mechanism and the guiding mechanism. It can also be horizontally moved through the casters at the bottom of the frame, which is convenient for cooperation with other docking devices and can also meet the different height requirements of packaging bags.

[0014] Since the present invention adopts the above technical solutions, including an air extraction mechanism, a heat sealing mechanism, a frame-type lifting mechanism, a transverse movement mechanism, a guiding mechanism connected to each other and a programmable industrial control computer connected by electric wires, it effectively solves the problem that the existing air extraction and heat sealing and bagging machine has a fixed body structure and is limited in being assembled into the multi-functional automatic large-bag material packaging production line. Also, the results of actual operation tests and trials show that it has the advantages of novel and practical overall structure, movable structure, automatic adjustment and transverse movement, and convenient use for heat sealing and bagging. It is suitable for being assembled into the multi-functional automatic large-bag material packaging production line and other material packaging machinery.
