Description

Prevent group bucket conveyer chain that bucket accelerates

Technical field

The utility model relates to a kind of load transfer device, is specifically related to a kind of group bucket conveyer chain that bucket accelerates of preventing.

Background technology

In flexible package punch field, packing barrel will be through a series of flow packages such as filling, capping, labeling, especially linear pattern filling production lines, per pass flow process packing barrel is all wanted equally spaced transportation, stop, is transported, and therefore dialling a bucket conveyer chain is the most frequently used load transfer device of packaging field.Dialling in the market barrel conveyer chain is all as shown in Figure 4, Figure 5, pushes away on the two adjacent bearing pins that stave is directly or indirectly arranged on chain.When conveyer chain end carries the chain that pushes away stave and moves in a circle around sprocket wheel from being linearly moved to, push away stave and can accelerate to turn forward like this, cause out a barrel unexpected hastening phenomenon, as shown in Fig. 6 motion simulation schematic diagram.When three chain pitch length of flexible element connecting rod mechanism movement, the upper end hinge-point of its vertical connecting rod and diagonal control arm moves to position C from position O, and straight-line distance is c; And only arrive position A during straight-line motion, and distance is a, distance c is much larger than apart from a, proves that pushing away stave has very large acceleration/accel to push away bucket going out barrel end.When the packing barrel of transportation is filled with fluid material and while there is no capping, the outside splash of liquid in bucket, not only affects filling accuracy and also pollute the environment.

For head it off, some enterprise has designed very complicated physical construction, for example in group bucket conveyer chain both sides, high speed conveyer chain is set, carry the chain of dialling stave around sprocket wheel, move in a circle before with regard to accelerated packet barrelling, packing barrel is departed from and dial stave, but owing to keeping away unavoidable packing barrel, accelerate, so still there is the hidden danger of splash material, do so in addition and virtually increased equipment cost.

Utility model content

The purpose of this utility model is: provide a kind of and prevent easily that bucket accelerates dials a bucket conveyer chain, while preventing from dialling bucket, liquid wherein spatters outward.

For achieving the above object, the technical solution of the utility model is: a kind of barrel conveyer chain of dialling of preventing bucket acceleration, comprise chain, dial stave and prevent a barrel acceleration mechanism, wherein: preventing barrel acceleration mechanism is triangle flexible element connecting rod mechanism, comprise: the vertical connecting rod of rigidity and diagonal control arm, vertical connecting rod and diagonal control arm upper end are hinged, lower end is hinged on respectively on the bearing pin of chain, portion of chain between 2 bearing pins that vertical connecting rod is connected with diagonal control arm is as flexible element, dial stave and be installed on vertical connecting rod, during work, bucket and diagonal control arm lay respectively at the both sides of vertical connecting rod.

The beneficial effects of the utility model: can effectively prevent that in prior art, conveyer chain end goes out a barrel hastening phenomenon, solve the packing barrel of filled with fluid material owing to accelerating and a difficult problem for splash material suddenly.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described further.

The utility model is not subject to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.

Below in conjunction with drawings and Examples, the utility model is further described:

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of barrel conveyer chain of dialling of preventing bucket acceleration, comprise chain 1, dial stave 6 and prevent a barrel acceleration mechanism, wherein: preventing barrel acceleration mechanism is triangle flexible element connecting rod mechanism, comprise: the vertical connecting rod 4 of rigidity and diagonal control arm 5, vertical connecting rod 4 and diagonal control arm 5 upper ends are hinged, lower end is hinged on respectively on the bearing pin of chain 1, the portion of chain that 2 bearing pins that vertical connecting rod 4 is connected with diagonal control arm 5 are 3 is as flexible element, dial stave 6 and be installed on vertical connecting rod 4, during work, bucket and diagonal control arm 5 lay respectively at the both sides of vertical connecting rod 4.

In the present embodiment, chain 1 is three row chains; Preventing barrel acceleration mechanism is comprised of two identical triangle flexible element connecting rod mechanisms, and be arranged symmetrically in three row chain both sides, dialling stave 6 is fixed on two vertical connecting rods 4, vertical connecting rod 4 and diagonal control arm 5 are hinged more than conveyer chain, lower end is hinged on respectively on the bearing pin of chain 1, and the chain between two bearing pins is equivalent to flexible soft bar.

In addition, the length of three bars of connecting rod mechanism can be calculated the acceleration/accel of dialling stave 6 according to the size of sprocket wheel and group stave 6, or directly carry out experimental observation, as long as can guarantee that flexible soft bar (sprocket wheel) is endways when sprocket wheel moves in a circle, group stave 6 being fixed on vertical connecting rod 4 can not accelerate suddenly to dial bucket, can not spill liquid.

So, when dialling stave and pushing away packing barrel and move to travel line end, chain carries flexible element connecting rod mechanism and pushes away stave and will move in a circle around sprocket wheel, as shown in Figure 6.If chain is still done straight-line motion, after three the chain pitch length of walking, the upper end hinge-point of its vertical connecting rod and diagonal control arm moves to position A from position O, and distance is a; And chain moves in a circle around sprocket wheel endways, under the effect of flexible element connecting rod, after three the chain pitch length of walking, the upper end hinge-point of its vertical connecting rod and diagonal control arm moves to position B from position O, and distance is b; Distance b is slightly larger than a in theory, and in fact due to push away stave be subject to packing barrel to back pressure, effect lower chain at three connecting rods can slightly be out of shape, be the chain hinge pin place of vertical connecting rod lower end can be slightly to perk outside sprocket wheel, cause and push away stave and recede, just in time made up the gap of distance b and a, final packaging bucket is substantially in uniform speed motion state.

Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that the utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, not departing under the prerequisite of design of the present utility model, can also make some deduction or replace, for example, chain can be also single, double or four rows etc.; In triangle flexible element connecting rod mechanism, the hinge-point of vertical connecting rod and diagonal control arm also can be in the lower end of chain, etc.These all should be considered as belonging to protection domain of the present utility model.

Above embodiment of the present utility model is explained in detail, above-mentioned embodiment is only optimum embodiment of the present utility model, but the utility model is not limited to above-described embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.
