The mechanical arm of bottle washing machine of band anti-fouler
Technical field
The present invention relates to be used in food, the pharmaceuticals industry bottle washing machine equipment of clean container, relate in particular to the mechanical arm of bottle washing machine of band anti-fouler.
Background technology
In the prior art, the mechanical arm of bottle washing machine is contained in the bearing block, bearing block and shelves water plate are (in the disc type bottle washing machine, this grade water plate is arranged to a circle of annular) be fixedly connected, some actuated elements also are housed on the mechanical arm, as control upset cam that mechanical handspring changes etc., mechanical arm and these actuated elements all need to apply lubricating oil at work, mechanical arm generally has two kinds of motions at work, a kind of is to make front-rear reciprocation movement under the support of sliding bearing, another kind is to rotate in sliding bearing, mechanical arm relies on the film lubrication that forms on it at the volley, though sliding bearing, bearing block and shelves water plate can play the effect of certain anti-lubricant pollution, but mechanical arm and sliding bearing rub for a long time and can produce the abrasion dust of trace and form greasy dirt, when stretching out sliding bearing, greasy dirt can be taken out of mechanical arm, when water for cleaning or steam spatter on mechanical arm, its water droplet can be with greasy dirt to splash in the rinse water together, influence the cleaning performance of bottle washing machine, and cause water resource waste, greasy dirt sticks on the mechanical arm in addition, influences the mechanical arm outward appearance.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, and the mechanical arm of bottle washing machine of the bright band anti-fouler of a kind of pollution, maintenance clean appearance simple in structure, that can effectively prevent water for cleaning is provided.
For solving the problems of the technologies described above, the present invention by the following technical solutions.
A kind of mechanical arm of bottle washing machine with anti-fouler, comprise mechanical arm, sliding bearing, water fender and bearing block, described bearing block is fixed in the water fender inboard, sliding bearing is installed in the bearing block, mechanical arm is set in the sliding bearing, and the described water fender outside is provided with the dirt proof sleeve that is placed on the mechanical arm.
Described dirt proof sleeve is provided with annular steps near an end of water fender, and this annular steps is fixedlyed connected with water fender through the positioning step of sliding bearing.
Compared with prior art, the invention has the advantages that: the water fender outside is provided with the dirt proof sleeve that is placed on the mechanical arm, when mechanical arm seesaws in sliding bearing, its extension that speckles with oil film or greasy dirt is among the containing of dirt proof sleeve, dirt proof sleeve can well be blocked rinse water or clean steam and spatter on mechanical arm, oil film on the mechanical arm and greasy dirt can not drop onto in the rinse water yet, in the pollution that effectively prevents water for cleaning, protection water resource, keep the mechanical arm clean appearance bright; Overall structure is simple, is convenient to make and install, and is durable in use.

The specific embodiment
As shown in Figure 1, the mechanical arm of bottle washing machine of band anti-fouler of the present invention, comprise mechanical arm 1, sliding bearing 2, water fender 3 and bearing block 4, bearing block 4 is fixed in water fender 3 inboards, sliding bearing 2 is installed in the bearing block 4, mechanical arm 1 is set in the sliding bearing 2, and water fender 3 outsides are provided with the dirt proof sleeve 5 that is placed on the mechanical arm 1.Dirt proof sleeve 5 can adopt welding with water fender 3, bonding, mode such as be threaded realizes being connected and fixed, adopted a kind of preferred version in the present embodiment, end at dirt proof sleeve 5 close water fenders 3 is provided with annular steps 6, this annular steps 6 places in the middle of the positioning step and water fender 3 of sliding bearing 2, and the positioning step that passes through sliding bearing 2 is fixedlyed connected with water fender 3, because sliding bearing 2 has certain length of fit with mechanical arm 1, sliding bearing 2 is an interference fit with bearing block 4, the quality of dirt proof sleeve 5 is again little, thus in this way fixedly dirt proof sleeve 5 be reliable.The mechanical arm of bottle washing machine of band anti-fouler of the present invention, overall structure is simple, is convenient to make and install, and durable in use; When mechanical arm 1 seesaws in sliding bearing 2; its extension that speckles with oil film or greasy dirt is among the containing of dirt proof sleeve 5; dirt proof sleeve 5 can well be blocked rinse water or clean steam and spatter on mechanical arm 1; oil film on the mechanical arm 1 and greasy dirt can not drop onto in the rinse water yet; in the pollution that effectively prevents water for cleaning, protection water resource, can also keep mechanical arm 1 clean appearance bright.
