Description

Chain elasticity adjusting mechanism of transition material way

Technical Field

The utility model relates to a transition material is said, specifically is a chain elasticity adjustment mechanism that transition material was said.

Background

The distance between the driven shaft and the driving shaft of the conventional transition material channel is fixedly kept, so that the distance between chain wheels fixed on the driven shaft and the driving shaft is not changed, and a chain is not easy to be tensioned on the chain wheels after being used for a long time, so that a supporting piece fixed on a chain link of the chain can shake, and the workpiece is conveyed unstably;

in conclusion, how to realize the chain tensioning on the chain wheel becomes a problem which needs to be solved urgently by researchers of the company.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: how to achieve chain tensioning on the sprocket;

in order to solve the technical problem, the utility model discloses a following technical scheme:

the utility model relates to a chain elasticity adjustment mechanism that transition material was said, include: a housing; the sliding chutes are formed in the two side walls of the shell along the length direction of the shell; the sliding block is movably arranged in the sliding groove; the end parts of the rotating shafts are fixedly connected with a sliding block; a sprocket fixed to the rotating shaft; the chain is wound on the chain wheel; the first fixing block is fixed on the side wall of the shell; the second fixed block is fixed on the sliding block; the push rod is connected with the first fixing block through threads, and the end part of the push rod movably penetrates through the second fixing block; the limiting block is fixed on the push rod; the elastic piece is sleeved on the limiting block, and the end part of the elastic piece is abutted against the end surfaces of the limiting block and the second fixing block respectively;

in this scheme, the slider is the activity setting in the spout, slider and pivot fixed connection, thereby realize the motion of slider for the casing, the push rod passes through threaded connection with first fixing base, the seesaw of push rod for first fixing base can be realized to the rotation push rod, the tip of push rod passes the second fixed block, slider and second fixing base fixed connection, be provided with the elastic component between second fixed block and the push rod, elastic component one end offsets with the stopper of fixing on the push rod, when the push rod moves forward for first fixing base, drive the second fixed block through the elastic component, the slide rail moves forward along the spout, when the second fixed block moves to extreme position, the push rod continues to move forward, thereby compress the elastic component, the elastic component gives the certain packing force of second fixed block, the return of restriction pivot.

In order to limit the maximum travel of the push rod, the limiting nut is arranged on the limiting rod, and the limiting nut abuts against the end face of the first fixed block when in the limiting position;

when the push rod moves to the maximum distance, the limiting nut is abutted against the first fixing block, and the push rod is limited to move continuously.

The utility model has the advantages that: the utility model relates to a chain elasticity adjustment mechanism that transition material was said, when the push rod moved forward for first fixing base, drive second fixed block, slide rail along the spout through the elastic component and move forward, when the second fixed block moved extreme position, the push rod continued to move forward to compress the elastic component, the elastic component gave the certain packing force of second fixed block, thereby the position of adjustment sprocket on the casing, with the chain tensioning all the time on the sprocket.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is an enlarged view of FIG. 1A;

in the figure: the device comprises a shell 1, a sliding chute 2, a sliding block 3, a rotating shaft 4, a chain wheel 5, a chain 6, a first fixing block 7, a second fixing block 8, a push rod 9, a limiting block 10, an elastic part 11 and a limiting nut 12.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1-2, the utility model relates to a chain elasticity adjustment mechanism of transition material way, include: a housing 1; the sliding chutes 2 are formed in the two side walls of the shell 1 along the length direction of the shell 1; the sliding block 3 is movably arranged in the sliding groove 2; the end parts of the rotating shafts 4 are fixedly connected with a sliding block 3; a sprocket 5 fixed to the rotary shaft 4; a chain 6 wound around the sprocket 5; a first fixing block 7 fixed on a sidewall of the case 1; a second fixed block 8 fixed to the slider 3; the push rod 9 is connected with the first fixing block 7 through threads, and the end part of the push rod is movably inserted into the second fixing block 8; a limiting block 10 fixed on the push rod 9; the elastic piece 11 is sleeved on the limiting block 10, and the end part of the elastic piece is abutted against the end surfaces of the limiting block 10 and the second fixing block 8 respectively;

As shown in fig. 2, in order to limit the maximum stroke of the push rod, the push rod 9 of the present invention is provided with a limit nut 12, and the limit nut 12 abuts against the end surface of the first fixing block 7 when in the limit position;

The utility model relates to a chain elasticity adjustment mechanism that transition material was said, when the push rod moved forward for first fixing base, drive second fixed block, slide rail along the spout through the elastic component and move forward, when the second fixed block moved extreme position, the push rod continued to move forward to compress the elastic component, the elastic component gave the certain packing force of second fixed block, thereby the position of adjustment sprocket on the casing, with the chain tensioning all the time on the sprocket.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
