Description

Technical Field

[0001] The invention relates to the field of automatic bag sewing, in particular to an M-type automatic bag sewing device. Background Art

[0002] Automatic bag sewing machines are equipment designed for sewing the mouths of plastic woven bags (objects), paper bags (objects), paper-plastic composite bags (objects), aluminum-coated paper bags, etc., and are mainly used to complete the splicing and sewing of bags or woven materials. The process features are good sealing after sewing, such as flour bags; high strength, such as cement bags; easy to disassemble, find the thread tail and pull it to loosen it, and the bag can be reused; currently, the domestic and Japanese and American automatic bag sewing machines are the most popular in the market;

[0003] Explosives are substances that can burn violently (i.e. explode) in a very short time. They are substances that explode under the action of a certain amount of external energy. Generally, the chemical and physical properties of explosives are stable. However, no matter whether the environment is sealed or not, how much explosives are used, or even when there is no oxygen supply from the outside, as long as there is strong energy (provided by the detonator) to stimulate them, the explosives will perform stable detonation work on the outside. When explosives explode, they can release a large amount of heat energy and produce high-temperature and high-pressure gas, which can destroy, throw, and compress surrounding substances.

[0004] When packing explosives into bags, the bagging device in the prior art has a straight-line seal before sealing, and there is a large gap in the bag after sealing. The explosive rolls placed inside are easy to loosen, which may cause safety hazards during transportation. Therefore, we propose an M-type automatic bagging device. Summary of the invention

[0005] The purpose of the present invention is to provide an M-type automatic bag sewing device to solve the problem raised in the above background technology that the bag sewing device in the prior art is sealed in a straight line before, and there is a large gap in the bag after sealing, so the explosive rolls placed inside are easy to loosen, which is easy to cause safety hazards during transportation.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The conveying mechanism conveys the explosive bag. When conveying to between the two clamping rollers, the first hydraulic rod drives the second connecting rod to move to the left, and the second connecting rod drives the two clamping rods to clamp the explosive bag. While clamping the explosive bag, the second hydraulic rod drives the third hydraulic rod to move to the right, and then the third hydraulic rod drives the clamping plate to clamp the bag horizontally, so that the sealing part of the explosive bag can be processed in M ​​shape, thereby effectively avoiding the situation that the gap in the bag after sealing is large due to the fact that the sealing of the bag sewing device in the prior art is in a straight line shape, and the explosive roll placed inside is easy to loosen, which is easy to cause safety hazards during transportation;

[0015] 2. Through the arrangement of the fixed plate, the sliding rod, the sliding sleeve and the third connecting rod, the horizontal plate can be driven to move left and right while the conveyor belt moves, and the explosive bags can be transported in cooperation with the conveying mechanism to avoid openings at the sealed ends of the explosive bags during transportation. Through the arrangement of the first transmission roller, the second transmission roller and the conveyor belt, the conveying mechanism can cooperate in transporting the explosive bags to the sewing machine to avoid the bags being unable to move due to clamping at the sealed ends of the bags. Through the arrangement of the motor, the second transmission roller can be powered to facilitate the synchronous movement of the first transmission roller and the second transmission roller. Through the arrangement of the conveying mechanism, the explosive bags can be transported to each working link. BRIEF DESCRIPTION OF THE DRAWINGS
