Description

Technical Field

[0001] The present invention belongs to the technical field of conveying devices, and more specifically, particularly relates to a turning device for placing cakes during the production of firecracker charging. Background Art

[0002] The charging process in firecracker production is the core link and also the most dangerous link in the firecracker production process. Once an accident occurs, the shock wave will also burst out through the entrance of the inserted fuse cake. If the staff placing the empty cakes happens to be in the same direction, they will be injured; to solve the above safety hazards, a turning device is needed. The turning device can transform the conveying equipment into an "L" shape, and the working position of the staff placing the cakes is far from the cake placing opening and is no longer in the same direction as the cake placing opening, reducing the safety hazard coefficient and effectively protecting the personal safety of employees.

[0003] The currently used turning conveying device still has the following problems:

[0004] 1. Although some turning conveying devices are equipped with protection structures to prevent staff from being pinched and avoid equipment damage, when foreign objects are stuck in the turning conveying device, it is impossible to timely remind the staff, which affects the conveying of materials;

[0005] 2. Generally, there is a lack of an automatic cleaning structure. During the use of the conveying rollers, dust, impurities, etc. will accumulate. If not cleaned in time, it will affect the normal operation of the equipment and the transportation efficiency. Summary of the Invention

[0051] The specific usage method and functions of this embodiment:

[0052] When the present invention is in use, first, the staff installs the device at the intersection of two conveying devices, connecting the left side and the rear side of the conveying support frame 101 to the two conveying devices. When conveying materials, the staff starts two servo motors 302 through the control box 200. When the servo motor 302 on the left front side works, a row of conveying rollers 102 on the left front side rotates. When the servo motor 302 on the right rear side works, a row of conveying rollers 102 on the right rear side rotates, realizing the automatic turning and conveying of materials. When the hand or other foreign objects of the staff are stuck on the conveying mechanism 100, the output shafts of the two servo motors 302 can squeeze the four circular positioning rods 305 to move outwards, separating the four circular positioning rods 305 from the four connecting card slots 3021. At this time, the two rows of conveying rollers 102 stop rotating, and the two servo motors 302 continue to work, playing a protective role for the staff and the conveying mechanism 100; it avoids the staff from being pinched and also avoids the damage of the conveying mechanism 100. When the output shafts of the two servo motors 302 squeeze the four circular positioning rods 305 to move outwards, the two connecting frames 304 can automatically press two switches A310, making the two buzzers 309 work, facilitating the staff to know that foreign objects are stuck in the conveying mechanism 100. When the staff removes the foreign object or their hand and then starts the two servo motors 302, the four circular positioning rods 305 can automatically insert into the four connecting card slots 3021 under the action of the four return springs A307, realizing the normal rotation of the two rows of conveying rollers 102.

[0053] When it is necessary to clean the two rows of conveying rollers 102, the staff extends the output shafts of the four electric cylinders 401 through the control box 200. When the output shafts of the four electric cylinders 401 extend, the cleaning support plate 403 drives the cleaning rag 404 to move upwards. When the cleaning rag 404 contacts the two rows of conveying rollers 102, when the output shafts of the four electric cylinders 401 continue to extend, the cleaning rag 404 elastically contacts the two rows of conveying rollers 102, and the four return springs B407 are slowly compressed. When the L-shaped pressing rod 408 presses the switch B409, the servo motor 302 on the left front side works, realizing the automatic cleaning of a row of conveying rollers 102 on the left front side. When the output shafts of the four electric cylinders 401 continue to extend and the L-shaped pressing rod 408 presses the switch C410, the automatic cleaning of a row of conveying rollers 102 on the right rear side is realized. It avoids the simultaneous rotation of the two rows of conveying rollers 102, so that the cleaning rag 404 is only subjected to a force in one direction during cleaning, which is beneficial to improving the service life of the cleaning rag 404. After cleaning, the staff retracts the output shafts of the four electric cylinders 401 through the control box 200.
