Under the premise of sealing oil-proof effect, facilitate the maintenance and maintenance of equipment.
The technical problems to be solved in the utility model is achieved through the following technical solutions,
A kind of cigarette machine spider sealing structure, including shell are provided with the capping of threaded connection, shell at the top of shell
The interior tooth shaft for stretching out 8 transmission arms, tooth shaft protected by sleeve, is offered in capping and one-to-one is led to for what tooth shaft passed through
The sleeve in hole, tooth shaft is passed through from through hole, in the present invention, the interior lateral edge edge sinking grooving of the through-hole, for sealing
Slot is fixed with O-ring seal in seal groove, and the internal diameter of sealing ring is not more than through-hole depths internal diameter, and the sleeve of the tooth shaft passes through
It is in close contact when through-hole with sealing ring, the medial surface of the sealing ring is provided with the limiting slot being recessed inwardly, corresponding, institute
The corresponding position for stating sleeve is provided with the limit rib of outwardly convex, and limiting slot is matched with limit rib, is the close of through-hole and sleeve
Cover adds curved surface, improves sealing effect.
In the present invention, the both sides of the limiting slot on the inside of the sealing ring raise into arc-shaped respectively, to intercept trace,
The relative displacement of limit rib and limiting slot is further limited, also further increases curved surface for the sealing surface of through-hole and sleeve, mentions
High sealing effect.
In the present invention, the internal diameter of the sealing ring inner side limiting-position slot is greater than through-hole depths internal diameter, so as to right
The limit rib of sleeve plays limit effect.
In the present invention, the upper surface of the capping is covered with backplate, and the size of backplate and capping are in the same size, on
Face be provided with the one-to-one sealing of hole of through-hole, sealing of hole internal diameter is consistent with upper through-hole depths internal diameter is covered, and sealing of hole closely connects with sleeve
Touching.
Further, the backplate is bolted to connection with capping.
In the present invention, the seal groove of the sealing ring and through-hole is in close contact or gluing is fixed, and is prevented unexpected de-
It falls and weakens sealing effect.
Compared with prior art, the utility model has the following beneficial effects:
(1) sealing that the utility model realizes through hole by the way that sealing ring is arranged in through-hole, improves sealing effect,
It is difficult to avoid the maintenance of adhesive sealing bring；
It (2) is the sealing of through-hole and sleeve by the cooperation of limiting slot, interception trace and the outer limit rib of sleeve on the inside of sealing ring
Circle increases multiple curved surfaces, greatly improves sealing effect；
(3) the outer backplate covered of capping makees further protection to the sealing ring of through-hole and through hole, prevents sealing ring from anticipating
It falls off outside and weakens sealing effect；
(4) part of the utility model change only has capping and sleeve for cigarette machine spider conveyer system,
It does not need to replace too many spare and accessory parts, reduces equipment improving cost.
To sum up, the utility model structure is simple, novel, and specific design of Sealing Structure greatly improves sealing effect
Fruit is also easy for installation and removal, easy access, and sealing effect is good, and equipment improving cost is low.
Detailed description of the invention
Fig. 1 is the equipment partial structural diagram of the utility model；
Fig. 2 is the closure construction schematic diagram of the utility model；
Fig. 3 is through-hole structure schematic diagram in the capping of the utility model.
In figure: shell 1, capping 2, transmission arm 3, sleeve 4, through-hole 5, seal groove 6, sealing ring 7, limiting slot 8, intercept trace 9,
Backplate 10.
Specific embodiment
The utility model is further described below in conjunction with Figure of description and specific preferred embodiment, but not because
This and limit the protection scope of the utility model.
Referring to cigarette machine spider sealing structure shown in Fig. 1-3, including shell 1, the top of shell 1 is provided with screw thread company
The capping 2 connect, the interior tooth shaft for stretching out 8 transmission arms 3 of shell 1, tooth shaft are protected by sleeve 4, are offered in capping 2 for tooth shaft
The sleeve 4 of the one-to-one through-hole 5 passed through, tooth shaft passes through from through-hole 5, and the interior lateral edge edge of the through-hole 5 sinks at close
Sealing groove 6 is fixed with O-ring seal 7 in seal groove 6, and the internal diameter of sealing ring 7 is not more than 5 depths internal diameter of through-hole, and the sleeve 4 is worn
It being in close contact when crossing through-hole 5 with sealing ring 7,7 medial surface of sealing ring is provided with the arc-shaped limiting slot 8 being recessed inwardly, with
It is corresponding, the corresponding position of the sleeve 4 is provided with the limit rib of outwardly convex, and limiting slot 8 is matched with limit rib, limit
The both sides of slot 8 raise into arc-shaped respectively, to intercept trace 9, further limit the relative displacement of limit rib and limiting slot 8, limit
The internal diameter of slot 8 is greater than 5 depths internal diameter of through-hole；The upper surface of the capping 2 is covered with backplate 10, the size and envelope of backplate 10
Lid 2 is in the same size, be provided with above with the one-to-one sealing of hole of through-hole 5, sealing of hole internal diameter with capping 2 on 5 depths internal diameter of through-hole it is consistent,
Sealing of hole and sleeve 4 are in close contact, and backplate 10 is bolted to connection with capping 2；The sealing ring 7 closely connects with seal groove 6
Touching or gluing are fixed, and prevent from surprisingly falling off and weakening sealing effect.
When cigarette machine spider sealing structure described in the utility model is applied in cigarette making machine conveyer system, transmission
The through-hole 5 that the tooth shaft of arm 3 passes through in capping 2 is stretched out out of shell 1, and centered on tooth shaft, transmission arm 3 is rotated to carry out cigarette
Work is transmitted, at this point, the sleeve 4 outside tooth shaft is located in through-hole 5, the limit rib on sleeve 4 is by the limit on 5 inner seal ring 7 of through-hole
Position slot 8 is limited.After the lubricating oil escaped in shell 1 drops onto capping 2, along between 4 outer wall of 5 inner wall of through-hole and sleeve to
Exosmosis, but the limit rib of the limiting slot 8 of sealing ring 7, interception trace 9 and sleeve 4 constitutes tortuous sealing surface, so that lubricating oil
It is difficult infiltration evolution.Meanwhile the backplate 10 covered in capping 2 also further protects entire sealing structure, so that close
It is more preferable to seal effect.
Therefore, novel in conjunction with above-mentioned construction and the course of work it can be found that the utility model structure is simple, it is specific
Design of Sealing Structure greatly improve sealing effect, be also easy for installation and removal, easy access, sealing effect is good, equipment
Improving cost is low.
