Abstract
A medical drug material conveying omega-shaped baffle longitudinal positioning closed transmission device is characterized by comprising a chain formed by alternately connecting vertically-placed closed sleeve arc vertical rings and horizontally-placed omega-shaped closed chain rings; the connecting parts of the omega-shaped closed chain rings are cambered surfaces, and the omega-shaped closed chain rings are connected with each other in a cambered surface contact manner; the omega-shaped closed chain ring comprises an omega-shaped body and a double-hole baffle plate arranged at the tail end of the omega-shaped body through a longitudinal detachable positioning pin. The medical drug material conveying omega-shaped baffle longitudinal positioning closed transmission device has the advantages of easy installation and disassembly, convenient maintenance, low cost, inter-link surface contact transmission, large bearing capacity, small contact stress, wear resistance, no pitch change, stable transmission, realization of precise transmission and long service life. The transmission system can be widely applied to the transmission system of medical drug material conveying equipment.
Description
Technical Field
The invention relates to a longitudinal positioning and sealing transmission device for an omega-shaped baffle for conveying medical drug materials, which can be widely applied to a transmission system of medical drug material conveying equipment.
Background
The existing medicine and drug material conveying equipment drags the bearing body by a chain and realizes the conveying of materials by the bearing body. Traditional round-link chain, chain link are woven by the round steel and form, and all chain link structures are the same, divide into flat ring and found the ring according to the position difference during the use. In the traditional circular chain structure, the bending radius of the circular ring is larger than that of round steel, so that the chain rings form linear contact transmission, and when the linear contact is under the same acting force, the contact surface of the chain rings is small, the stress is large, and the chain rings are easy to wear.
A structure with the bending radius larger than that of the round steel is compiled according to the circular ring of the circular ring chain, namely, the turnabout turning center line is not overlapped with the center line of the chain ring; this arrangement produces a pitch change during redirection, i.e. both relative rotation and relative sliding between the links. The pitch is reduced by a different amount for different redirection angles, and this change in pitch increases transmission instability. The line contact that its structure of above-mentioned analysis produced easily produces wearing and tearing, and the pitch of wearing and tearing back chain ring can increase again, and the change of pitch can bring the transmission unstability, and unstability can aggravate wearing and tearing to cause vicious circle, make the chain life-span extremely low. The structural characteristics of different change of the direction change angle and different pitch also bring difficulty to the manufacturing standardization of the conveying equipment.
The traditional annular chain is formed in a welding and sealing mode, and needs to be intercepted according to the actual length during use, so that waste is generated. When in butt joint, an additional connecting ring needs to be added, the price of one connecting ring is about two meters of the price of the chain, and the cost is high. When a certain chain ring has a problem, the chain ring is usually demolished destructively by gas cutting, which not only has difficult maintenance and long time consumption, but also needs to prepare a maintenance tool, set up safety protection of flammable and explosive gases, and causes the defects of environmental pollution and the like.
Disclosure of Invention
The invention aims to provide the longitudinal positioning closed transmission device for the medical drug material conveying omega-shaped baffle, which has the advantages of high connection strength, easiness in installation and disassembly, convenience in overhaul and maintenance, low cost, surface contact transmission among chain rings, high bearing capacity, small contact stress, wear resistance, no change in pitch, stable transmission, capability of realizing precise transmission and long service life.
In order to achieve the aim, the medical drug material conveying omega-shaped baffle longitudinal positioning closed transmission device comprises a chain formed by alternately connecting vertically-placed closed sleeve arc vertical rings and horizontally-placed omega-shaped closed chain rings; the connecting parts of the omega-shaped closed chain rings are cambered surfaces, and the omega-shaped closed chain rings are connected with each other in a cambered surface contact manner; the omega-shaped closed chain ring comprises an omega-shaped body and a double-hole baffle plate arranged at the tail end of the omega-shaped body through a longitudinal detachable positioning pin.
The medical drug material conveying omega-shaped baffle longitudinal positioning closed transmission device adopts a longitudinal detachable positioning pin and baffle structure, has high connection strength, easy installation and detachment, convenient maintenance, local replacement and low cost.
Compared with the traditional round-link chain, the longitudinal positioning closed transmission device of the omega-shaped baffle for conveying medical drug materials has essential difference in structure. The chain rings are in surface contact transmission, so that the bearing capacity is high, the contact stress is small, the chain rings are wear-resistant, the pitch cannot be changed, the connection is reliable, the transmission is stable, the precise transmission can be realized, and the service life is long.
In conclusion, the medical drug material conveying omega-shaped baffle longitudinal positioning closed transmission device has the advantages of easiness in mounting and dismounting, convenience in overhauling and maintenance, low cost, surface contact transmission among chain rings, high bearing capacity, small contact stress, wear resistance, no change of pitch, stable transmission, capability of realizing precise transmission and long service life.
