Description

Belt feeding rack and feeding method thereof

Technical field

The present invention relates to a belt feeder for a molding machine for manufacturing a tire blank and a feeding method thereof, and belongs to the field of rubber machinery.

Background technique

The belt feeding device of the forming machine is used for guiding, transporting, correcting, measuring, cutting, etc. after one of the half parts of the belt material for forming the tire blank is guided from the storage vehicle. A mechanical device that is attached to the belt drum.

Chinese Patent No. 201120570317. 0 discloses a belt supply rack comprising a frame, a transport formwork bracket disposed on the frame, and a transport template located on the transport formwork support along the belt The conveying direction of the layer is inclined downward, and has a front end that is attached to the belt drum. The front end of the conveying template is located under the belt drum, and when the conveying template is at the fitting station, the upper surface thereof is opposite to the outer circumference of the belt drum. cut. The frame is provided with a vertical adjustment device for swinging the front end of the conveyor holder up and down, and a fulcrum for swinging the conveyor holder up and down. The fulcrum is a pivoting shaft of the frame and the pivotal joint of the transport template bracket, and the vertical adjusting device comprises a bevel track disposed on the frame and a slider slidable on the inclined track. For car radial tires that only need to be fitted with two layers of belts, the technical solution achieves automatic and continuous production, and the work efficiency is relatively high. For all-steel radial truck tires, it is usually necessary to apply the belt materials of 1#, 2#, 3#, 4# four-layer structure and different shapes to the belt drum in turn, so the technical solution cannot be satisfied. Production requirements for truck tires.

The current all-steel heavy-duty belt-belt supply rack usually has four layers of feeding templates vertically arranged at the front end corresponding to the four-layer belt layer, and each feeding template sequentially feeds the belt drums, and the layers are respectively fed. The layers are applied to the belt drum in turn. This technical solution takes up a lot of space and is expensive to produce.

Summary of the invention

The object of the present invention is to provide a full-automatic belt supply rack, which divides the feeding template into two parts: a conveying template and a bonding template, each of which corresponds to a plurality of conveying templates, and respectively through the positioning adjusting device Each conveying template cooperates to pick up materials provided by different conveying templates. By sharing a single template and a reasonable layout of each template through multiple conveying templates, the occupied space is reduced and the manufacturing cost is reduced.

Another object of the present invention is to provide a belt layer feeding method, which realizes continuous feeding of belt layers of each layer and automatic continuous bonding on the belt drum, and has reasonable process arrangement and high work efficiency. No need for labor Participate.

To achieve the above object, the belt supply rack is used for conveying and fitting the belt material on the belt drum disposed in front of the belt, and includes: a frame on which the base and the vertical adjustment are disposed The device is pivotally connected to the frame through the pivot shaft, and rotates around the pivot shaft under the action of the vertical adjusting device; the vertical adjusting device is connected to the front end of the base.

The difference from the prior art is that a conveying template for carrying and conveying the belt layer and a belt for continuing to convey the belt layer and attaching to the belt drum are sequentially disposed on the base along the conveying direction of the belt layer. The template is attached to the splicing template; at least two splicing templates are arranged, and at least two conveying templates are arranged at the back end of each splicing template; and each conveying template for realizing the splicing template and the rear end thereof is arranged on the pedestal Coordinated positioning adjustment device.

Based on the above basic scheme, the feeding template of the belt feeding frame is divided into two parts: a conveying template and a bonding template, and the two have a many-to-one relationship in quantity and layout, that is, a plurality of conveying templates are attached to one. The template conveys the material; under the action of the positioning adjustment device, the bonding template can be alternately matched with the respective conveying templates, and the materials provided by the different conveying templates are taken, and sequentially attached to the belt drum.

In order to make the layout of the belt feeding rack more reasonable, the above technical solution is further optimized, and two matching templates arranged side by side in the same plane are arranged on the base, and the back end of each bonding template is correspondingly Set up two vertically distributed transport templates.

The two bonding templates are distributed on both sides of the belt drum, and when they are attached to the belt layer, they are sequentially brought into the bonding station which cooperates with the belt drum. In order to facilitate the fit and fall of the template into and out of the bonding station, the bonding template is slidably connected to the base through the sliding rails provided on the base.

In order to realize that the bonding template respectively picks up materials from the two conveying templates at the rear end thereof, the positioning adjusting device is a cylinder disposed on the base, and the end of the cylinder piston rod is connected with the bonding template to drive the bonding template. It swings up and down along the connecting shaft with the front end of the base, and the connection point is preferably disposed at the rear end of the fitting template. When the cylinder rod is retracted, the fitting template cooperates with the lower conveying template at the rear end thereof to pick up the belt layer on the lower conveying template; when the cylinder piston rod extends, the bonding template and the upper layer conveying template at the rear end thereof Cooperate with the belt layer on the upper conveying template.

When the belt layer on the bonding template is attached to the belt drum, under the driving action of the vertical adjusting device, the base rotates around the pivoting shaft, and the front end of the bonding template is swung upward to load the bonding template. The belt is in a position tangent to the belt drum, and then the belt is attached to the belt under the rotation of the belt drum On the outer circumference of the layer drum.
