Abstract

A lath rail transmission chain of sorting machine is a sleeve rolling chain which is composed of an external and an internal chain-sheet, a chain-sheet connecting pin, and a pin sleeve. Wherein the external which is at on one side of the chain is a special external chain board; the lower part of the external chain board connects with one end of the chain-sheet connecting pin, and the upper part is connected with the top part of the lath rail through the screw; a horizontal roller axis with walking rollers is fixed in the middle of the external chain-sheet, and one edge of the external plate is provided with a right angle plate; a roller axis with guiding rollers is fixed vertically on the horizontal plate of the right angle plat, the walking rollers is supported on the chain rail, and the guiding rollers leans against the edge of the lateral plates of the chain rail, furthermore, the walking and the guiding rollers are all encapsulation bearing rollers. The utility model has the advantages that the utility model simplifies the walking and the guiding roller and the installation structure, which provides the convenience to the installation and maintenance; the production cost is low, thus the device is suitable to the lath rail transmission of the light sliding shoe parcel sorting machine to sort small goods.

Description

The lath rail driving chain of sorter

Technical field

The utility model relates to the driving chain that is used to drive the running of lath rail in a kind of the mechanical drive chain, particularly pushing block-style sorting machine.

Background technology

Existing pushing block-style sorting machine, its driving chain that drives the running of lath rail is bearing on the chain track plane and drags walking, and friction drag is big during work, and noise is big, and driving efficiency is low, thereby the higher pushing block-style sorting machine of incompatibility operating speed.For this reason, the applicant had once designed a kind of " low noise messenger chain of slat conveyer " that is suitable for pushing block-style sorting machine, and applied for patent (patent No. ZL200420021801.8), it comprises that the outer Chain link for chain grate that constitutes chain, interior Chain link for chain grate, Chain link for chain grate connect the connection carrier bar of bearing pin and the outer Chain link for chain grate of an alternative side, its walking roller is made up of hollow roller axle, opening elastic ring, elastic ring, back-up ring, bearing, wheel housing, and its guide roller is made up of hollow roller axle, back-up ring, bearing, wheel housing.This driving chain running is steadily reliable, and noise is low, but structure is relatively complicated.

Summary of the invention

The purpose of this utility model, be that above-mentioned " the low noise messenger chain of slat conveyer " carried out technological improvement, thereby a kind of advantage that not only has above-mentioned " the low noise messenger chain of slat conveyer " is provided, and structure is simpler, novel low-noise driving chain easy to assembly, that manufacturing cost is lower.

Technical solution of the present utility model is: this driving chain is by outer chain sheet, inner chain sheet, the chain sheet connects bearing pin, the sleeve-barrel roollr chain that the bearing pin sleeve constitutes, wherein the outer chain sheet of chain one side is the purpose made pin link plate, this pin link plate lower end is connected bearing pin with the chain sheet a end is connected, the upper end is provided with bolt hole, can be connected in the end of lath rail by screw, the pin link plate middle part is fixed with the horizontal roller axle, on the horizontal roller axle walking roller is installed, one side portion of pin link plate is provided with a L-square, vertical fixing has the roller shaft of tape guide roller on the horizontal plate of L-square, walking roller is supported on the chain rail, guide roller then hands down with the side plate of chain rail and leans on, and described walking roller and guide roller are the encapsulate bearing roller.

The utility model has been simplified walking roller and guide roller and mounting structure thereof, has made things convenient for to install and maintenance, and low cost of manufacture, is particularly suitable for sorting the lath rail transmission of the light-duty pushing block-style sorting machine of small article.

The specific embodiment

The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.

Chain 7 is the sleeve-barrel roollr chains that are made of outer chain sheet 16, inner chain sheet 13, chain sheet connection bearing pin 14, bearing pin sleeve 15, but a wherein side outer chain sheet of chain 7 substitutes with purpose made pin link plate 2.This pin link plate 2 is the square plate of four jiaos of roundings, its underpart offers the end that two adjacent on pair of pin axis hole and chain chain sheets are connected bearing pin 14 and is connected, pin link plate 2 tops offer two bolts hole, so that pin link plate 2 is fixed in the end of lath rail 1 with screw 4, pin link plate 2 middle parts are fixed with horizontal roller axle 11 and walking roller 6 by screw-nut 12, one side portion of pin link plate 2 also is provided with a L-square that is bent into from bottom to top 8, with bolt and nut 10 vertical fixing roller shaft 9 and guide roller 3 is arranged on the horizontal plate of L-square 8.The walking roller 6 of present embodiment and guide roller 3 are covered with engineering plastics lasso 18 on bearing 17 outer ring side faces and the encapsulate bearing roller of formation, and its structure is very simple, and is easy to manufacture, and cost is low, and installation and maintenance are easy.Each walking roller 6 of this driving chain is supported on the chain rail 5, guide roller 3 then the edge by the side plate of chain rail 5.During the sorter running, driving chain 7 relies on its walking roller 6 to contact with chain rail 5 with guide roller 3, and operation friction power is little, the driving efficiency height, and noise is low.
