Also know some stoves, they include staggered relatively, and the shipment axle of the passage that matches with lid is installed, and by the effect that described axle rotatablely moves, lid moves up to upper area.Then, lid is transferred on two decline axles, this make lid slide onto outlet downwards in a similar fashion.

The failure problems that this system has results from the upper area when lid moves to the decline axle by the rising axle, and because the problem that lid when motion friction causes.Be worth to propose also have the device running time vibration that causes and its continuous-flow system that is comprised additional difficulty of causing.

In the face of this situation, the answer of Ti Chuing is to be connected with a whirligig having the fixedly bailing bucket that dwindles contact surface herein, like this, can ends with regard to rest on bailing bucket, thereby described lid can be dried more equably.Be that this whirligig is mounted to the distance that makes between bailing bucket and keeps identical, thereby the can ends that only has same size could be dried in addition.

Patent of invention 921930 and 921985 by same holder of the patent right is also learnt, they have proposed to give has circle, the machine in Qinghua on the can ends of shapes such as ellipse, herein, stove is placed in described outlet of going up Qinghua machine, like this, the oven dry of lid just can be used as a continuous part of Qinghua process.The invention overview

The present invention attempts to adopt some improvement to solve the problems referred to above to existing system, thereby is dried the can ends of various sizes and shape, and is applied to the control to drying time, makes the part in addition of production have better fineness.

The invention of Ti Chuing herein is made up of a stove, and its purpose is the can ends of drying Qinghua or living through the liquid rubber coating operation, and its chief component is a mechanism that can be adjusted in the feed column width that wherein transports lid.Described lid fricton-tightly is fixed on the bearing, and bearing then can be by the effect campaign of the haulage chain that is connected with them, thereby because this mechanism has avoided the friction and the vibration that produce usually in these devices.

So just may put into difformity, no matter be foursquare, circular or oval-shaped big small lid because its adaptation is easy, thereby has guaranteed that stove uses more widely.

The chain that is used for drawing the bailing bucket of supporting lid is installed in feed column, and the distance between its end points is by being regulated with moving of described chain pinion in mesh.

Equipped an endoporus in the pinion, some minor axis ends that are connected with axle have been installed in the hole, the size according to drying lid places the appropriate location with locking fixture, thus the distance between axle control pinion.

Also comprised heteroid lid, no matter these lids be the plane or Double bottom, transport the possibility that enters stove.

At the plane cover subcase, lid is transported helping by four on the determined three groove bailing buckets, and four ribs are used to support lid, and are porose in two grooves, be used for bailing bucket with transport the screw that chain is connected and pass through thus.Single groove bearing is used to transport the Double bottom lid, rib or outstanding on two holes also are installed similarly, rib or outstanding between be inner groovy, lid is placed in wherein.

The end chain is meshed with upper and lower pinion, thus the motion of setting up each chain according to closed circulation, according to the associating displacement of definite each bailing bucket that is connected with chain of selected circulation.The lid of putting into by stove inlet, be placed on the corresponding bailing bucket one by one successively, then in the move upward cross section on reaching pinion mate place of vertical direction, they cause that one rotatablely moves around it, the vertical decline of the latter reaches the exit conveyor level until them, just be placed on the conveyer belt, by conveyer belt it loaded and transported out stove then.

During transporting each lid by stove, keep at their baked strengths in whole stroke identical, thereby lid is dried equably.

Lid enters bailing bucket for convenience, they have one can regulate transport sector to the outlet and the control drying time of conveyer belt, determine the step motion of chain surely, make it just and stove feeding mechanism synchronised, can make lid enter feed column singly like this and come out with feed column.Can avoid the continuous obstructing problem that turns round and cause with this method.

The lid feed system that adopts the present invention to propose can obtain higher running speed and a series of such as eliminating improvement such as the friction of discovery and vibration usually in other drying oven.Summary of drawings
