AI Technical Summary
The transmission mechanism of existing fireworks and firecrackers equipment involving explosives does not have an effective sealing method when passing through the wall, resulting in the transmission shaft being exposed in the wall, which is easily contaminated and poses a safety risk of explosives spreading into the power room.
A sealing structure is installed at the hole through which the transmission mechanism passes through the explosion-proof wall. This structure includes a sleeve fitted on the transmission shaft, a protective plate, and a bearing structure. The sleeve is designed to be retractable to accommodate different wall thicknesses, and the bearing structure isolates the equipment room and the power room.
It achieves effective sealing of the drive shaft, preventing dust accumulation and drug diffusion, improving the safety and service life of the equipment, and making it more widely applicable.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fireworks and firecracker machinery, specifically relating to a through-wall structure for the transmission mechanism of fireworks and firecrackers equipment involving explosives. Background Technology
[0002] To ensure safe production, explosion-proof walls are required to separate the working devices of fireworks and firecracker equipment from their power units, creating two independent indoor spaces: an equipment room and a power room. The current practice involves directly connecting the transmission mechanism, which connects to the power unit, through a hole in the explosion-proof wall. This method exposes the transmission shaft directly to the wall without protection, making it susceptible to dust and other contaminants. Furthermore, the equipment and power spaces are not completely isolated, allowing chemicals to easily diffuse into the power room during production, posing a safety risk. Therefore, it is necessary to improve the existing technology to address the sealing and safety issues of the transmission mechanism's wall penetration in fireworks and firecracker equipment involving chemicals. Utility Model Content
[0003] The purpose of this utility model is to provide a through-wall structure for the transmission mechanism of fireworks and firecrackers involving pharmaceuticals, which has good sealing and safety.
[0004] The technical solution adopted to achieve the purpose of this utility model is as follows:
[0005] The wall-penetrating structure of the transmission mechanism for fireworks and firecrackers involving explosives provided by this utility model includes an explosion-proof wall with perforations, and the transmission mechanism passing through the perforations and connected to the working device and power device of the fireworks and firecrackers involving explosives. The characteristic is that a sealing structure is provided inside the perforations of the wall, which is fitted onto the transmission mechanism to seal the transmission mechanism.
[0006] The transmission mechanism includes a transmission shaft connected to the power device, and the sealing structure includes a sleeve sleeved on the transmission shaft, protective plates provided at both ends of the sleeve and fixed to the wall, and a bearing structure provided on the protective plate to support the transmission shaft.
[0007] The sleeve adopts a telescopic structure, and the protective plate and bearing structure are respectively installed on different sleeves. Beneficial effects
[0008] Compared with the prior art, the transmission mechanism in this utility model has a sealing structure at the perforation of the explosion-proof wall, which avoids the exposure of the transmission shaft, has better dustproof capability, effectively protects the transmission mechanism, and can extend its service life. The sealing structure adopts a telescopic sleeve structure, which can be used to install the transmission mechanism on explosion-proof walls of different thicknesses, making it more versatile. When the equipment is running, the protective steel plate installed at the perforation of the explosion-proof wall can isolate the equipment room and the power room, which has better explosion-proof function and prevents the accumulation of generated drug dust in the perforation and its diffusion into the power room, thus avoiding safety hazards.
[0009] The technical solution of this utility model will be further described below with reference to the accompanying drawings. Attached Figure Description

[0012] See Figure 1 , Figure 2 The wall-penetrating structure of the transmission mechanism of fireworks and firecrackers involving drugs provided by this utility model includes an explosion-proof wall 2 with a through hole 201, a transmission mechanism that passes through the through hole 201 and is connected to the working device 5 and the power device 1 of the fireworks and firecrackers involving drugs, and a sealing structure 3 that is sleeved on the transmission mechanism to seal the transmission mechanism is provided in the through hole 201 of the wall 2.
[0013] The transmission mechanism includes a transmission shaft 6 connected to the power unit 1. The sealing structure 3 includes a sleeve fitted onto the transmission shaft 6, protective plates 302 located at both ends of the sleeve and fixed to the wall 2, and a bearing structure on the protective plate 302 supporting the transmission shaft 6. The bearing structure includes a bearing 303 fixed to the protective plate 302 via a bearing seat 301. The protective plate 302 can be made of steel and fixed to the wall 2 with expansion bolts, which helps to isolate the equipment room and the power room, preventing drug dust from accumulating in the perforation and spreading to the power room, thus avoiding safety hazards. The bearing 303 can be a mounted bearing for easy installation.
[0014] The sleeve employs a telescopic structure, which can be a two-tube telescopic structure or a multi-tube telescopic structure. A two-tube telescopic structure is as follows: Figure 2 As shown, it includes a first sleeve 304 and a retractable second sleeve 305 fitted inside the first sleeve 304. The protective plate 302 and the bearing structure are respectively provided on the first sleeve 304 and the second sleeve 305. The retractable structure of the sleeve can adapt to different wall thicknesses for installing the transmission mechanism.
[0015] In use, this invention connects the drive shaft 6 to the power unit (explosion-proof motor) 1 of the fireworks and firecrackers explosive-handling equipment located on one side of the explosion-proof wall 2. Then, the power shaft 4 of the working device 5 of the fireworks and firecrackers explosive-handling equipment located on the other side of the explosion-proof wall 2 is connected to the drive shaft 6 via a coupling 7. The power unit 1 drives the working device through the drive shaft 6. The working device 5 can be the core transmission device, fabric transmission device, and conveying transmission device of an automatic firecrackers explosive-handling machine in the fireworks and firecrackers production process, or the transmission device, fabric and conveying device of an automatic explosive-handling machine for fireworks inner tubes, etc.
