Abstract

The utility model relates to a flat-top conveyor chain for conveying bottles, boxes, pots, etc. The utility model comprises a chain plate body and a chain plate block. The chain plate block is cast or welded with the chain plate body to form a seamless integral structure. The chain plate block is provided with a pin hole. The periphery of the pin hole is sealed. The utility model has the advantages that the abrasive resistance is favorable, the service life improves two times, the production cost is reduced, the pulling and the extending phenomena and tip climbing are not generated in the conveying period, the both ends of the lower surface of the chain plate body which is worn with a cushion strip are smooth planes, the pin hole in the chain plate body is precisely expanded through drilling machines, and the central distance of the chain plate after mutually connected is precise and reasonable.

Description

The flat-top transporting chain plate

The utility model relates to the flat-top conveyer chain that is used to carry bottle, case, jar etc., more particularly is the flat-top transporting chain plate that connects and composes the flat-top conveyer chain.

Existing flat-top conveyer chain is made up of a plurality of flat-top transporting chain plates that link together by bearing pin, is linked together by two fixed pin holes, movable pin-and-hole with bearing pin that above-mentioned pin-and-hole forms interference fit, free-running fit respectively between the adjacent flat-top transporting chain plate.And existing flat-top transporting chain plate is dashed by sheet material and is rolled into shape, because above-mentioned fixed pin holes and movable pin-and-hole also are to be curled by flat board to form, thereby the pin-and-hole that does not form border seal promptly the periphery of this pin-and-hole also leave the slit, in course of conveying as when folder bottle, folder case, little the increasing of load occurring, the slit of pin-and-hole periphery is easily drawn back on the flat-top transporting chain plate; Again because the pin-and-hole on the flat-top transporting chain plate is to be curled by flat board to form, thereby the shape of this pin-and-hole is nonstandard and few with the direct connect face of bearing pin, it is very fast to rub, the pitch of flat-top conveyer chain is increased, cause flat-top to carry chain and sprocket to climb point, the flat-top conveyer chain is carried not steadily, is easily beated, and has shortened the operating cycles of flat-top conveyer chain more than 60% widely.

The purpose of this utility model will provide exactly that a kind of resistance to abrasion is good, long service life, conveying pulsation-free flat-top transporting chain plate.

In order to achieve the above object, technical solution of the present utility model is: the flat-top transporting chain plate comprises chain plate body, chain plate, and this chain plate and chain plate body are the seamless integrative-structure by casting or being welded, and this chain plate is provided with the pin-and-hole of border seal.

The cross-sectional plane of this chain plate can rounded, ellipse garden shape or polygon.

Flat-top transporting chain plate after the improvement is by the precision cast once-forming and becomes seamless one that because movable pin-and-hole and fixed pin holes on the chain plate are blind hole, resistance to abrasion is good, has improved 2 times service life, has reduced productive costs; The phenomenon of can never occur drawing back the flat-top transporting chain plate during carrying, elongating the flat-top conveyer chain can not climbed point; With filler strip mutually the two ends of the flat-top transporting chain plate lower surface of break-in be smooth flat, freely smooth through washing flat processing; Pin-and-hole on the flat-top transporting chain plate makes the width between centers after the flat-top transporting chain plate interconnects accurately reasonable through the accurate reaming of drilling machine.

Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail:

Description of drawings: the three-dimensional structure diagram that Fig. 1 matches for a plurality of flat-top transporting chain plates

The front view that Fig. 2 matches for a plurality of flat-top transporting chain plates

Fig. 3 is the birds-eye view of Fig. 2

Fig. 4 is A-A cutaway view of Fig. 2

By Fig. 1, Fig. 2, Fig. 3 and Fig. 4 as can be known, the flat-top transporting chain plate can make chain plate and chain plate body 1 become seamless integrative-structure by the precision cast once-forming; Certainly, existing flat-top transporting chain plate can make the pin-and-hole that has the slit become the through hole that seamless pin-and-hole is a border seal by welding.

The material of this flat-top transporting chain plate is a corrosion-resistant steel, and it comprises chain plate body 1,

chain plate

2,3, and this chain plate is a solid cylinder, and its cross-sectional plane can rounded, ellipse garden shape or polygon.Be respectively equipped with the pin-and-

hole

5,6 of border seal on this

chain plate

2,3, this pin-and-hole 5 is the movable pin-and-hole that forms free-running fit with bearing pin 4, and pin-and-hole 6 then is the fixed pin holes that forms interference fit with bearing pin 4.

The upper surface of this chain plate body 1 is the plane, the two ends of its lower surface are smooth flat, the one side is provided with two chain plates 3 spaced apart, opposite side then is provided with one and the corresponding chain plate 2 of above-mentioned distance, and the width of this single chain plate 2 is less than the distance between above-mentioned two chain plates 3, this chain plate obtains above-mentioned standard compliant pin-and-hole through the accurate reaming of drilling machine, and this pin-and-

hole

5,6 can guarantee that the width between centers after a plurality of chain plate bodys 1 interconnect by bearing pin 4 is accurately reasonable.

The single chain plate 2 of a flat-top transporting chain plate is inserted in the space between two chain plates 3 of another flat-top transporting chain plate, and make the pin-and-hole 6 on bearing pin 4 and two the chain plates 3 form interference fit, and form free-running fits with pin-and-hole 5 on the single chain plate 2; A plurality of like this flat-top transporting chain plates interconnect by bearing pin 4 and have just constituted the flat-top conveyer chain.

Claims

1, the flat-top transporting chain plate comprises chain plate body (1), chain plate (2) (3), it is characterized in that described chain plate (2) (3) and chain plate body (1) are the seamless integrative-structure by casting or being welded, and are respectively equipped with the pin-and-hole (5) (6) of border seal on this chain plate (2) (3).
