Related content in above-mentioned technical proposal is explained as follows：

1st, in such scheme, the limiting device includes two pairs of rolling mechanisms, which includes four rollings Unit, two rolling units therein are fixed in a side region of supporting bar stent, the fixed setting of another two rolling unit In another side region of supporting bar stent.

2nd, in such scheme, the line of centres and another lateral areas of two rolling units in one side region of supporting bar stent The line of centres of two rolling units on domain is parallel, and the centerline parallel with the network chain of horizontal transport along its length.

3rd, in such scheme, two equal arranged for interval of rolling unit in each side region of supporting bar stent.

4th, in such scheme, the rolling unit includes an axis, a bearing and a ring-type bushing, the axis and is fixed on institute State on supporting bar stent, the ring-type bushing is rotatablely connected by the relatively described axis of the bearing；The bearing have an inner ring and One outer ring, the bearing are set on axis, and bearing inner race relative axle is fitted close, and the ring-type bushing is set on bearing, And bearing outer ring is fitted close with respect to ring-type bushing.

5th, in such scheme, the axis is threadedly secured on the supporting bar stent.

6th, in such scheme, an axis snap ring is equipped between the axis and bearing, is equipped between the ring-type bushing and bearing Hole snap ring.

Utility model works principle is：Original guide plate is substituted for the rolling that can be oriented to and can reduce frictional force Moving cell, when network chain is in transmitting procedure, when the both sides of the edge of network chain are bumped against on rolling unit, the friction that occurs with rolling unit For roller friction, and since loss that rolling friction produces is far smaller than the loss that sliding friction produces, therefore can effectively reduce Network chain transmitting procedure abrasion, so as to extend the service life of network chain.

Since above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：

The utility model is of simple structure and low cost, good reliability, good stability, by the slip between network chain and guide plate Friction is converted into rolling friction, so as to effectively reduce the abrasion that network chain both sides of the edge are subject to, extends the service life of network chain.

Embodiment

The utility model is further described with reference to the accompanying drawings and embodiments：

Embodiment 1：A kind of limiting device for transmitting network chain

Referring to attached drawing 1-2,1 bottom of network chain is equipped with supporting bar stent 2, and 2 both sides of supporting bar stent are respectively equipped with a support plate 3, network chain 1 drives the transmission movement of network chain 1 by the rotation of glue coating wheel 5, and the both ends of glue coating wheel 5 are connected respectively by bearing block 6 In two support plates 3.

Referring to shown in attached drawing 1, in the present embodiment, the limiting device includes two pairs of rolling mechanisms positioned opposite, each Rolling mechanism is formed by two rolling units 4, which is respectively fixedly disposed at the supporting bar On the left and right sides region of stent 2, the network chain 1 is located between two roller units 4 is oriented to limit by two roller units 4 Position, and the tangential direction that two roller units 4 roll is consistent with the transmission direction of network chain 1.Specifically, in the present embodiment Two pairs of idler wheel mechanisms include four rolling units 4, and two rolling units 4 therein are fixed at a lateral areas of supporting bar stent 2 On domain, another two rolling unit 4 is fixed in another side region of supporting bar stent 2, and two in each side region roll 4 equal arranged for interval of moving cell.
