Background

The tread is the most important part in the tire, and is the heaviest part (about 30%) in the tire simultaneously, and as shown in fig. 1-2, the existing tread production conveying, storing and cutting processes need to be cut according to the standard length (the length of a single tread is about 3 m) when the tread of the heavy duty tire is produced. When the cutting knife of the cutting device 1-6 starts to cut the tire tread, the cutting conveyer belt 1-3 needs to stop cutting the tire tread 1-1, and after the cutting knife finishes cutting and returns to the starting point, the cutting conveyer belt 1-3 can continue to convey the tire tread 1-1 forward to cut again. When the action of cutting the tire tread 1-1 by the cutter is started, the cutting conveyer belt 1-3 is in a pause state, the tire tread 1-1 conveyed by the linkage line falls into the storage tank 1-5 (the storage tank is about 1.2 meters deep, and the tank bottom and the cutting conveyer belt are about 1.8 meters high) for storage, after the cutting action of the cutter is finished, the ultrasonic sensor 1-2 detects the position of the valley point of the falling tire tread 1-1 and then the encoder 1-4 converts the data into the conveying speed of the cutting conveyer belt 1-3 for conveying (the conveying speed is converted into different conveying speeds according to the detected position point, namely the distance between the valley point of the tire tread and the ultrasonic sensor is larger, and the starting speed of the cutting conveyer belt is higher). When the cutting conveyer belt starts, the cutting conveyer belt is influenced by factors such as the dead weight of the tire tread of the material storage tank, the friction between the tire tread and the cutting conveyer belt, the high initial speed of the cutting conveyer belt and the like (the length of the stored tire tread is 2.5-2.6 meters, the dead weight of the tire tread with a slightly larger specification is about 20 kg), the length change of the tire tread conveyed by the cutting conveyer belt is large, the stability of the cut tire tread length is poor, the qualified rate of the tire tread is influenced, and the production efficiency is reduced.

Detailed Description

In order to make the purpose and technical solution of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings.

Increase on current linkage line tread storage mode based on current extrusion production line includes extrusion equipment, linkage line, cutting device etc. the utility model discloses an extrusion tread storage lifting and conveying device to solve the tread and cut back length stability poor, the many problems of length defective products.

As shown in FIG. 3, the extruding tread storing, lifting and conveying device comprises a device support 1, wherein the device support 1 comprises an upper support 11, a middle support 12 arranged in parallel with the upper support 11 and a vertical support 13 arranged perpendicular to the upper support 11.

Be fixed with guide bracket 6 on vertical support 13, guide bracket 6 is located the top of middle part support 12, be provided with guide pulley 8 on the guide bracket 6, guide pulley 8's recess joint has direction straining device 4, direction straining device 4 passes guide pulley 8's upper portion back one end and is connected with balancing weight 5, the other end is connected with gravity roller 7, gravity roller 7 and balancing weight 5 mainly realize and material storage tread from gravity matching, the effect of neutralization material tread dead weight.

The guiding and tensioning device 4 can be a tensioning rope, one end of the guiding and tensioning device is connected with a balancing weight 5, and the other end of the guiding and tensioning device is connected with a gravity roller 7. The gravity roller 7 is connected with the counterweight 5 through a tensioning rope. The gravity roller 7 is a driven roller and can rotate freely, the gravity of the gravity roller 7 is generated by a balancing weight 5 connected with a tensioning rope and slides up and down through a guide pulley 8. The balancing weight 5 can be manually reduced or increased according to the specification and the size of the tire tread, the storage length and the like, and is convenient to use.

The storage belt tensioning device 2 is a supporting tensioning device which is fixed on the left side and the right side of the upper support 11 and the middle support 12 respectively, and the storage belt 3 is sleeved on the periphery of the supporting tensioning device in a sleeved mode. Carry out the inseparable taut fixed of four points to

storage area

3, 3 lower parts of storage area are contradicted with

gravity roller

7, and 3 upper portions of storage area are used for accepting the storage tread, and the width of storage area 3 and storage area straining device 2's length are confirmed according to tread specification size.

Support straining device can be for being fixed in two slide bars of upper portion support 11 and two slide bars on the middle part support 12 respectively, and the tight ring cover of storage area 3 is in the periphery of 4 slide bars, carries out the inseparable taut fixed of four points to

As shown in fig. 3 to 4, the specific embodiment is:

in the tread production, the tread is conveyed to a cutting device by a cutting conveyer belt for cutting, when the moving amount of the cutting conveyer belt reaches a set value, the cutting conveyer belt stops moving, and meanwhile, a cutter falls down to cut the tread. When cutting the conveyer belt stall, the tread that the continuous transport of linked line came falls down to an extrusion tread storage lifts conveyor's storage area 3 on, can cause the increase of gravity to oppress downwards and make storage area 3 sink because of the increase of storage length when the tread in the in-process of continuous whereabouts storage, the storage area 3 that is located gravity roller 7 top oppresses gravity roller 7 downstream simultaneously. The more treads are stocked on the stock belt 3 and the heavier the gravity, the lower the gravity roller 7 will fall to neutralize the self-gravity of the stocked treads. Gravity roller 7 is connected with balancing weight 5 through the taut rope, and the gravity of gravity roller 7 is produced by balancing weight 5 to slide from top to bottom through leading pulley 8, after the cut-off knife cut the tread action, cut the conveyer belt and start, tread storage length or reduce from gravity, gravity roller 7 just can slide under the effect of balancing weight 5 and rise to the normal position that returns, waits for the next storage action. In the tread production, the operations of storing materials, lifting and conveying and cutting are continuously and repeatedly carried out.

Will the utility model discloses an extrusion tread storage lifting conveyor installs in the storage tank, when the tread enters into storage state, the tread falls down and carries out automatic storage above one kind extrusion tread storage lifting conveyor's the storage area 3, lift conveyor and go up the tread of gravity roller 7 and balancing weight 5 weight and play the lift storage because of receiving an extrusion tread storage, thereby it is undulant to reduce or solve the transport length that causes because of the dead weight completely to alleviate the self gravity of the tread of storage, cut the unqualified problem of back tread length.

The device effectively solves the problems of poor cutting length stability caused by the influence of dead weight of the tire tread and the change of friction force between the tire tread and the cutting conveyor belt, and the problem that the harmony of the storage belt 3 and the gravity roller 7 is poor or collision occurs in the tire tread in the storage process, and manual intervention on the tire tread storage is not needed in the increase and decrease of the balancing weight 5, the increase and decrease are convenient, and the production process is simple.

As the utility model discloses a another kind of improvement does, the distance is less than about two directional rollers of upper portion support 11 about two directional rollers on the support 12 of middle part to under the same storage area 3 displacement circumstances, turn into the up-and-down motion displacement of bigger middle part support 12 storage area 3 with about the distance displacement of the outside storage area 3 of upper portion support 11, oppress and make the storage area 3 that is located gravity roller 7 top sink and have bigger effort oppression gravity roller 7 downstream simultaneously.
