Abstract

The utility model discloses an improved conveyor chain belt, which comprises a plurality of chain sheets connected via connecting pins, a pin lug is arranged on each side of the rear end of each chain sheet, and the front end of the pin lug has an inclined plane structure. In the improved conveyor chain belt provided in the utility model, the front end of the pin lug has the inclined plane structure, so that the adjacent chain sheets are capable of rotating at a large angle around the connecting pin to be directly matched with the chain wheels with smaller diameter. The improved conveyor chain belt has the advantages of small floor area, low consumption of chain sheets, and low production cost.

Description

The improved type conveyor chain

Technical field

The utility model relates to a kind of conveyor chain that uses on the travel line track.

Background technology

China No. 200320118191.9 patent disclosure a kind of novel conveyor chain, it is used on the travel line track of packaging product, is applicable to the conveying of light-end productss such as cigarette bar cigarette, various packaged food, medicine.This novel conveyor chain includes some chain sheets and some connecting pins, the A end and the B end of chain sheet are respectively equipped with pin-and-hole, the B end of back one chain sheet is placed on the set groove C of last chain sheet A end, and make the pin-and-hole of back one chain sheet B end corresponding with the position of last chain sheet A end pin-and-hole, and by in the connecting pin insertion pin-and-hole adjacent two chain sheets being connected, the A end both sides of its medium chain sheet are respectively equipped with the pin ear, two pin ears are provided with the catch jack that communicates with pin-and-hole, pin-and-hole is a long slot bore, it between connecting pin and the pin-and-hole free-running fit, catch inserts respectively in the two catch jacks, and retaining is put the end at pin-and-hole and connecting pin.

This novel conveyor chain has adopted and has been free-running fit between connecting pin and the pin-and-hole, by catch insert in the catch jack, retaining puts the structure in pin-and-hole and connecting pin end, therefore, connecting pin has mobile space in pin hole, so not only can the tune-up center distance, and easy to assembly, the setting accuracy height; In addition, the insertion of catch is guaranteed that pin can not become flexible and is skidded off, and makes that overall appearance of the present utility model is generous.Simultaneously, after catch inserts, keep between the chain sheet certain clearance being arranged, make like this can relatively swing certain angle between the chain sheet, the whole piece chain belt just can bend to certain arc, but make not only moving linearly of whole piece chain belt, also can do circular motion, during the design of whole piece travel line, can be transported to material on any position from a position, make things convenient for the unit design of workshop layout, simplified the design of delivery system, reduced the cost of travel line.

But, this existing conveyor chain is on sprocket wheel the time, because stopping mutually between the outstanding pin ear of each chain sheet, each chain sheet can not be done the rotation of wide-angle around connecting pin, therefore must be equipped with larger-diameter this conveyor chain of sprocket wheel ability fit on, so, whole device has just occupied bigger factory building space, and needs more chain sheet to make productive costs higher.

Summary of the invention

At the shortcoming that background technology indication conveyor chain exists, the purpose of this utility model is that the described conveyor chain of background technology is made improvements, and a kind of improved type conveyor chain is provided, can be directly and assemble than the sprocket wheel of minor diameter.

To achieve these goals, the technical solution of the utility model is: a kind of improved type conveyor chain, include that some the both sides, rear end of each chain sheet are respectively equipped with the pin ear by connecting pin bonded assembly chain sheet, and the front end of described pin ear is set to ramp structure.

Described ramp structure further comprises an inclined-plane and a vertical surface, and described inclined-plane runs through the end face of pin ear and forms described vertical surface to oblique rear extension more vertically downward to closing on the place, bottom.

The gradient on described inclined-plane is preferably 45 degree.

Compared with prior art, the front end of improved type conveyor chain pin ear of the present utility model is set to ramp structure, make the adjacent chain sheet do rotation around connecting pin than wide-angle, can be directly assemble with sprocket wheel than minor diameter, whole device need not take more space, and only need use less chain sheet productive costs is reduced; The inclined-plane runs through the end face of pin ear and forms vertical surface to oblique rear extension more vertically downward to closing on the place, bottom, the gradient on inclined-plane is preferably 45 degree, after using this kind ramp structure, the chain sheet can be done the more rotation of wide-angle around connecting pin, keeps its due strength and stiffness simultaneously well.

Description of drawings

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

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the birds-eye view of Fig. 1.

The specific embodiment

See also Fig. 1 and Fig. 2, the improved type conveyor chain of present embodiment includes that some the both sides, rear end of each chain sheet 1 are respectively equipped with pin ear 2 by connecting pin 5 bonded assembly chain sheets 1, and the front end of pin ear 2 is set to ramp structure; Preferably, this ramp structure further comprises an inclined-plane 3 and a vertical surface 4, and inclined-plane 3 runs through the end face of pin ear 2 and forms vertical surface 4 to oblique rear extension more vertically downward to closing on the place, bottom, and the gradient on inclined-plane 3 is 45 degree.

The improved type conveyor chain of present embodiment can be used on the nine less toothed chain wheels 6 of diameter, and the conveyor chain of prior art can only be assemblied on the 13 bigger toothed chain wheels of diameter and uses.

Though the utility model discloses as above with a preferred embodiment, be not in order to limit the scope that the utility model is implemented.Any those of ordinary skill in the art, in not breaking away from invention scope of the present utility model, when doing a little improvement, promptly every equal improvement of doing according to the utility model should be invention scope of the present utility model and contains.

Claims

1, a kind of improved type conveyor chain includes that some the both sides, rear end of each chain sheet are respectively equipped with the pin ear, it is characterized in that by connecting pin bonded assembly chain sheet, and the front end of described pin ear is set to ramp structure.

2, improved type conveyor chain according to claim 1 is characterized in that, described ramp structure comprises an inclined-plane and a vertical surface, and described inclined-plane runs through the end face of pin ear and forms described vertical surface to oblique rear extension more vertically downward to closing on the place, bottom.

3, improved type conveyor chain according to claim 2 is characterized in that, the gradient on described inclined-plane is 45 degree.
