Description

Automatic tensioning mechanism of plate chain line

Technical Field

The utility model relates to a plate link chain technical field specifically is an automatic straining device of plate link chain line.

Background

The plate chain type conveying line is often needed in the logistics and manufacturing industries, and the plate chain type conveying line is the most suitable solution for many factories due to the simple and reliable structure and the low price. The plate chain line utilizes a motor to drive a chain wheel on a driving shaft to rotate through a transmission mechanism at the line head position, and then drives a chain and a chain plate on the chain to move forwards, so that various required functions are realized. The corresponding thread tail part is provided with a chain wheel for tensioning, and the chain wheel is tensioned towards the thread tail direction by a screw rod to prevent the chain from loosening. In the chain use, the chain can lead to chain length to increase because of running-in, consequently needs artifical timing inspection chain running state, adjusts the tensioning screw, avoids the chain to run in the back overlength and leads to the chain flagging to produce the risk.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an automatic straining device of plate link chain line to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a plate link chain line automatic take-up mechanism, includes tensioning frame, tensioning axle, tensioning sprocket, sliding bearing seat, chain, tensioning screw, nut, it is provided with sliding bearing seat to slide on the slide rail on the tensioning frame, sliding bearing seat sets up at tensioning axle both ends, the epaxial tensioning sprocket that still is provided with of tensioning, the last chain that is provided with of tensioning sprocket, sliding bearing seat and tensioning screw one end are connected, threaded connection has the nut on the tensioning screw, be provided with the elastic component between nut and the tensioning frame, the elastic component cup joints on tensioning screw, the through-hole on the tensioning frame is worn out to tensioning screw one end, elastic component and nut are located the paragraph of the tensioning screw between sliding bearing seat and the tensioning frame.

Preferably, the elastic member is a tension spring.

Preferably, the tensioning screw and the sliding bearing seat are in threaded connection.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses, there is not artifical risk of periodic inspection hourglass inspection, does not cause the risk of equipment maloperation, and the intensity of labour who has reduced corresponding operating personnel can be big more.

Fig. 1 is a schematic structural view of an automatic plate link chain tensioning mechanism in the prior art of the present invention;

fig. 2 is a schematic structural diagram of the present invention.

In the figure: 1. a tension frame; 2. tensioning the shaft; 3. a tension sprocket; 4. a sliding bearing seat; 5. a chain; 6. Tensioning the screw; 7. a nut; 8. an elastic member.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 2, the present invention provides a technical solution: the utility model provides a plate link chain line automatic take-up mechanism, including tensioning frame 1, tensioning shaft 2, tensioning sprocket 3, sliding bearing seat 4, chain 5, tensioning screw 6, nut 7, it is provided with sliding bearing seat 4 to slide on the slide rail on tensioning frame 1, sliding bearing seat 4 sets up at 2 both ends of tensioning shaft, still be provided with tensioning sprocket 3 on the tensioning shaft 2, be provided with chain 5 on the tensioning sprocket 3, sliding bearing seat 4 and the connection of tensioning screw 6 one end, threaded connection has nut 7 on the tensioning screw 6, be provided with elastic component 8 between nut 7 and the tensioning frame 1, elastic component 8 cup joints on tensioning screw 6, through-hole on tensioning frame 1 is worn out to tensioning screw 6 one end, elastic component 8 and nut 7 are located the tensioning screw 6 paragraph between sliding bearing seat 4 and the tensioning frame.

In particular, the elastic member 8 is a tension spring.

Specifically, the tension screw 6 is in threaded connection with the sliding bearing block 4.

The working principle is as follows: original mechanism scheme is with nut 7 welding on tensioning frame 1, and tensioning screw 6 rotates in the nut and be the rigid connection between tensioning frame 1: as long as the tensioning screw 6 does not rotate, the position of the sliding bearing block 4 is fixed, the tensioning chain wheel 3 and the tensioning shaft 2 cannot move, the chain 5 naturally sags when being loosened, and the tensioning screw 6 is adjusted to be tensioned again until the manual inspection is found.

In order to solve the problem of manual adjustment of the mechanism, a tensioning spring is additionally arranged for automatic adjustment, and flexible connection between a tensioning screw 6 and a tensioning frame 1 is achieved. Can be good with moment and regulation surplus length calibration when the design installation, at the life-cycle use of chain 5 in, the tensioning spring will follow the tensioning direction and will push away tensioning sprocket 3 is automatic, avoided 5 slackens of chain and droops to lead to risks such as equipment jamming, jump tooth.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
