Description

Technical Field

[0001] The utility model relates to the technical field of bag making and folding, in particular to a folding mechanism for a traditional Chinese medicine bag making machine. Background Art

[0002] At present, packaging bags include plastic packaging bags, PET packaging bags, PP packaging bags, etc. Packaging bags are mainly used for product packaging to facilitate subsequent safe transportation. In order to reduce the generation of garbage, many existing packaging bags are made of paper packaging bags, which can reduce the generation of "white garbage" after use, thereby improving the environment. In the processing of packaging bags, some packaging bags need to be folded. Different packaging bags have different folding requirements. The existing folding mechanism can only fold a fixed width. When folding operations are required for different packaging bags, the entire folding mechanism needs to be directly replaced, which will waste a lot of time and reduce work efficiency. Therefore, we propose a folding mechanism for a bag making machine.

[0003] The existing public technology disclosed in publication number CN210590774U discloses a folding mechanism of a bag making machine, including a frame and a conveyor belt, the conveyor belt is located on the inner side of the frame, and the upper end surfaces of the front and rear sides of the conveyor belt are fixed with folding plates, the folding plates are two, and the inner upper ends of the folding plates are provided with flip plates, the folding plates are fixed to the frame through a mounting plate, and the surface of the mounting plate is provided with an adjustment groove, and a bolt is inserted in the adjustment groove, and the bolt is screwed into a screw groove provided on the surface of the frame. The utility model fixes the folding plate used for folding to the frame through the mounting plate, and the surface of the mounting plate is provided with an adjustment groove, and the bolt passes through the adjustment groove and is screwed to fix the mounting plate, so that the mounting plate can change the length of the folding plate extending to the conveyor belt surface through the adjustment groove, thereby facilitating the adjustment of the folding width, without the need to replace the entire folding device, and the operation is simple and saves a lot of time.

[0004] Although the above patent can adjust the folding width and the operation is relatively simple, there are still some shortcomings in its use. First, the patent adjusts the extension length of the folding plate to the conveyor belt by rotating the bolts on both sides of the folding plate, and then adjusts the width of the fold. It is necessary to turn multiple bolts to adjust the folding width once, which is not convenient to use and may affect work efficiency. Secondly, the position of the roller used to press the packaging bag in this patent is fixed, and the thickness of the packaging bag that needs to be folded may be different, which may cause the patent to be unable to fold packaging bags of different thicknesses. The applicability is not strong enough. At present, no effective solution has been proposed for the problems in the relevant technology. Utility Model Content

When it is necessary to fold the packaging bag, the main body of the packaging bag passes under the turntable 28 in the groove of the folding block 5, and the two sides of the packaging bag are folded by the turntable 28. The space between the top and the bottom of the groove top is passed through to fold the packaging bag. When the width of the fold needs to be adjusted, the first motor 16 is started to rotate to drive the bidirectional screw 20 to rotate. Since the limit block 22 at the top of the folding block 5 and the bidirectional screw 20 are a threaded connection structure, the limit block 22 can be driven to move left and right by rotating the bidirectional screw 20. The left and right movement of the limit block 22 drives the movement of the folding block 5 to adjust the distance between the two folding blocks 5, thereby realizing the flexible adjustment of the folding width. The packaging bag after folding passes between the first pressing cylinder 13 and the second pressing cylinder 14, and the folded edge of the packaging bag is compacted and fixed by the first pressing cylinder 13 and the second pressing cylinder 14.
