Abstract

The utility model relates to a conveying chain. The conveying chain comprises a framework, four guide pillars are arranged at the upper portion of the framework and are provided with a plurality of support plates, the support plates are hinged with clamping plates, jointing air cylinders are arranged two ends of each support plate, each clamping plate is provided with a clamping air cylinder which is provided with a self-centering connection piece connected through a screw rod. The conveying chain has the advantages that by means of the creative structural design, procedure equipment is saved, work efficiency is improved, the use rate of turnover trays is improved, the use number of the turnover trays is reduced, only one tenth of originally used turnover trays are needed, the purchasing cost for a user is reduced, and the production cost of products is lowered. In addition, the conveying chains are maintained after stacked in a wet mode, only one third of the original maintenance space is needed, the occupied space is saved, and the energy consumption is lowered.

Description

A kind of chain

Technical field

The utility model relates to a kind of chain, relates in particular to a kind of roller class chain.

Background technology

Chain kind in the market is a lot, but does not satisfy some special operating mode demands.For example, transported material when through sprocket wheel upset occuring, keep transported material to be in the center constant in being transferred the chain-driving traveling process.The general chain of market all is to utilize the hole on the chain outer panel to fix, so that transported material and chain centre plane have certain distance, does not just satisfy same focal need when chain oppositely drives.

The utility model content

The purpose of this utility model is to provide a kind of conveyor chain, on the basis of the basic need that satisfies existing chain, guarantees that further in chain course of conveying transported material is in the center of chain all the time.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of chain comprises the chain body, and described chain body comprises roller, sleeve, inner plate and pin link plate, is provided with the bearing pin that matches with roller in the described chain body, and described bearing pin one end is provided with the plane step, and the bearing pin opposite side is provided with clip; Described plane step is provided with needle plate.

Further, described plane step overlaps with the longitudinal plane of symmetry of described bearing pin.The connection mode of described plane step and needle plate is for being spirally connected or riveting.

The beneficial effects of the utility model are: by the structure design of innovation, so that when dragging transported material by chain, transported material is no matter be at chain forward or antikinesis, or there being sprocket wheel to change the center that all is in chain when chain turns to, made things convenient for the use of chain transport structure.

Description of drawings

The below is described in further detail the utility model with reference to the accompanying drawings.

Fig. 1 is the structural representation birds-eye view of the described a kind of chain of the utility model embodiment;

Fig. 2 is the structural representation lateral plan of the described a kind of chain of the utility model embodiment;

Fig. 3 is the structural representation elevational cross-sectional view of the described a kind of chain of the utility model embodiment;

Fig. 4 is the use side view of the state of the described a kind of chain of the utility model embodiment;

Fig. 5 is the use state birds-eye view of the described a kind of chain of the utility model embodiment.

Among the figure:

11, roller; 12, sleeve; 13, inner plate; 14, pivot pin; 15, pin link plate; 16, clip; 17, needle plate; 21, chain body; 22, transported material; 23, sprocket wheel.

The specific embodiment

Shown in Fig. 1-5, the described a kind of chain of the utility model embodiment, comprise chain body 21, described chain body 21 comprises roller 11, sleeve 12, inner plate 13 and pin link plate 15, be provided with the bearing pin 14 that matches with roller 11 in the described chain body 21, described bearing pin 14 1 ends are provided with the plane step, and bearing pin 14 opposite sides are provided with clip 16; Described plane step is provided with needle plate 17.

Further, described plane step overlaps with the longitudinal plane of symmetry of described bearing pin 14.The connection mode of described plane step and needle plate 17 is for being spirally connected or riveting.

During concrete the use, such as Fig. 4, shown in Figure 5, transported material 22 hangs on the needle plate 17.When the chain 21 that is fixed with 17 needle plates drives transported material 22 through sprocket wheel 23, can overturn, just because of the innovation chain 21 has special pivot pin 14 structures, so that the surface of transported material 22 is on the longitudinal plane of symmetry of chain all the time.

The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
