Description

Technical Field

[0001] The utility model relates to the technical field of bulk grain detection, and specifically relates to a vertical sealing mechanism of a packaging bag forming device. Background Technique

[0002] Bulk grain detection refers to the inspection and testing of the edible quality, nutritional components, and other physical, chemical, and biological characteristics of grains to ensure the safety of grains. After the bulk grain detection is completed, a packaging bag forming device is used to package the bulk grains, and the vertical sealing mechanism needs to work in cooperation when using the packaging bag forming device.

[0003] For example, the publication number CN203865065U discloses a continuous edge-sealing and forming device for packaging bags used for food packaging, which includes a frame, a packaging paper conveying frame, and a packaging paper conveying channel. The packaging paper conveying frame conveys the packaging paper, and the packaging paper is folded in half at the folding part through the packaging paper conveying channel. The folded packaging paper enters the edge-sealing frame of the edge-sealing mechanism, and the two sides of the packaging paper are sealed by a heating sheet, so that the packaging paper becomes a tubular packaging bag. This continuous edge-sealing and forming device for packaging bags realizes continuous production, improves the processing efficiency, and enhances the degree of automation of processing. However, when using this continuous edge-sealing and forming device for packaging bags, there are still other deficiencies. Since there is no guiding function during the edge-sealing process of the food packaging bag by the continuous edge-sealing and forming device for packaging bags, the edge-sealing is directly carried out, making it easy for the bag mouth to be misaligned, resulting in poor sealing effect and the need for rework, reducing the edge-sealing efficiency of the packaging bag. Therefore, when using this device, there are still certain deficiencies. Content of the Utility Model

The number of pressing wheels 5 is two, and the pressing lines connected by the two pressing wheels 5 are designed in a staggered manner. By moving the two pressing wheels 5 and the guiding wheel 6 appropriately within the fixed seat 4 and fixing the pressing wheel 5 and the guiding wheel 6 on the fixed seat 4 with corresponding nuts, the distance between the two pressing wheels 5 and the guiding wheel 6 can be adjusted. Then, manually pass the packaging bag filled with bulk grain through the two pressing wheels 5 and the guiding wheel 6, so that the pressing lines provided on the two pressing wheels 5 initially press the packaging bag, and the guiding wheel 6 guides and conveys the initially pressed packaging bag, avoiding the situation of poor subsequent sealing effect due to misalignment of the bag mouth, and improving the subsequent vertical sealing efficiency of the packaging bag filled with bulk grain.

[0031] Embodiment 2: The packaging bag can be vertically sealed. Reference can be made to the attached Figure 1 - attached Figure 2and appendix Figure 5 - appendix Figure 7 , a telescopic cylinder body 8 is arranged on the right side of the fixing plate 7, a fixed shaft 9 is fixedly installed at the output end of the telescopic cylinder body 8, and a first support arm 10 is sleeved on the outer wall of the fixed shaft 9.
