Problems solved by technology

[0003] The tensioning device on the traditional double-chain conveyor generally uses nuts and screws to directly tighten the chain. The chain tightening operation is not only time-consuming and laborious, but also easily leads to inconsistent tension of the chain due to asynchronous tightening of the chain, and is prone to chain skipping, drag chain and chain abnormalities. Abrasion problem, affecting conveying stability
In addition, the tensioning device on the traditional double-chain conveyor has no overload and chain breaking protection mechanism, which is easy to cause safety accidents and bring heavy losses to production

Embodiment Construction

[0014] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0015] As shown in the figure: the chain tensioning device in the embodiment is mainly composed of a tensioning wheel assembly 1, a slider 2, a tensioning frame 3, a tensioning screw assembly 4, a chain guide frame 5, an adjustable foot 6, and a trigger plate 7 , travel switch 8, switch mounting frame 9, lower guide bar 10, guide groove frame 11 and upper guide bar 12 etc. are formed.

[0016] like Figure 1~Figure 3 As shown, the tension frame 3 is supported by the adjustable feet 6 at the bottom thereof, and the slider 2 is installed on the tension frame 3 and can slide freely horizontally and laterally. In the embodiment of the present invention, horizontal and transverse long grooves are provided on the slide plates on both sides of the tensioning frame 3, and the slide block 2 is mainly composed of two side slide plates and a connecting plate. Be provide...

Abstract

The invention relates to a chain tensioning device. A tensioning frame is supported by adjustable at the bottom of the tensioning frame, a slide block is installed on the tensioning frame and can slide horizontally, transversely and freely, and a tensioning wheel assembly is installed on the slide block. A tensioning screw assembly is arranged on the right of the tensioning wheel assembly and comprises a tensioning screw, a limiting plate, a volute spiral spring and a spring seat, wherein the spring seat is fixedly installed on the tensioning frame, the volute spiral spring is installed in the spring seat, the tensioning screw is arranged horizontally and transversely and penetrates through the center of the volute spiral spring, the front end of the tensioning screw is connected with the slide block and is locked by using a nut, the limiting plate is installed in the middle of the tensioning screw and is locked by using a nut, and the head end of the volute spiral spring ejects and presses the limiting plate from right to left. The chain tensioning device is simple and reasonable in structure and capable of saving effort during chain tensioning operation and conducting synchronous tensioning adjustment on chains of a double-chain conveyor, avoids the problems including chain jumping, chain dragging and abnormal chain abrasion caused by inconsistent tensioning forces of the chains of the double-chain conveyor and can provide overload and broken-chain protection.

Description

technical field [0001] The invention relates to a chain tensioning device, in particular to a chain tensioning device used on a double-chain conveyor, and belongs to the technical field of conveying equipment. Background technique [0002] The double-chain conveyor is mostly used in the skid conveying system, and is generally used in the workpiece conveying in the process section of the production workshop. One end of a common double-chain conveyor is a driving device, and the other end is a tensioning device. Through the operation of the driving motor, the entire conveyor is driven to run along the required logistics direction at a certain speed. [0003] The tensioning device on the traditional double-chain conveyor generally uses nuts and screws to directly tighten the chain. The operation of tightening the chain is not only time-consuming and laborious, but also easily leads to inconsistent tension of the chain due to asynchronous tightening of the chain, and prone to ch...
