Abstract

The invention discloses a plane flat-pressing type high-load-bearing bearing chain. The plane flat-pressing type high-load-bearing bearing chain comprises a chain body formed by a plurality of chain units through a connection plate hinge; each chain unit comprises an n-shaped inner buckle plate formed in a compression molding manner; the upper top face of each n-shaped inner buckle plate is a load-bearing conveying face; the front end and the rear end of standing plates on the two sides of each n-shaped inner buckle plate are symmetrically provided with pin holes; a pin shaft arranged between the pin holes of the front end and the rear end of the standing plates on the two sides of each n-shaped inner buckle plate in a penetrating and sleeved manner is sleeved with left and right load-bearing bearings; and a chain wheel rotating shaft sleeve is arranged between the corresponding left and right load-bearing bearings. The plane flat-pressing type high-load-bearing bearing chain has the beneficial effects of being ingenious and reasonable in structure, high in load bearing capacity and small in resistance. The plane flat-pressing type high-load-bearing bearing chain is used in cooperation with a matched conveying track and can completely meet the high-load-bearing accurate transferring requirement of a super-high weight object (paper pile) of a sheet-fed offset press.

Description

technical field

[0001] The invention relates to a chain, in particular to a plane flat pressure high-load bearing chain. Background technique

[0002] In the paper product processing industry, there are roughly two types of logistics methods used to transport materials, one is roller logistics and the other is crawler logistics. The characteristics of these two logistics methods are that the weight of the materials to be transported is relatively light, and the accuracy of the logistics is not high. In the watermark industry, knitted conveyor belts and plastic conveyor belts are also used, but this conveyor belt is not suitable for the offset printing industry. Since the weight of the paper pile on the sheet-fed offset printing machine is as high as about 4 tons, and in order to ensure the quality of the printed products, the accuracy of the logistics is required to be high, so the general conveyor belt cannot meet the zero-error logistics of the sheet-fed offset printing m...

Embodiment Construction

[0015] Such as figure 1 , 2 As shown in , 3, the plane flat pressure high load bearing chain of the present invention includes a chain body formed by a plurality of chain units hinged through the connecting plate 1, the chain unit includes a molded door-shaped inner buckle plate, and the door-shaped The upper top surface 2 of the inner gusset is the load-bearing conveying surface, and the front and rear ends of the vertical plates 3 on both sides of the door-type inner gusset are symmetrically provided with pin holes 4; The pin shaft 5 between the pin holes is covered with left and right load bearings 6, between the left and right load bearings, a sprocket rotation bushing 7 is arranged, and spacers 8 are arranged on both sides of the left and right load bearings 5.

[0016] In order to ensure the flexibility of the chain, the front and rear ends of the vertical plates 3 on both sides of the door-shaped inner gusset are in a semicircular structure, and the distance between th...
