Belted layer feed rack of giant embryo shaping machine

Abstract

The invention discloses a belted layer feed rack of a giant embryo shaping machine, comprising a conveying mechanism, a fixed frame, a feed template and a movable frame, wherein the conveying mechanism is provided with a material pouring prevention structure, the feed template is provided with a centering device, and the movable frame is arranged on the fixed frame in a mode of moving back and forth; the end part of the feed template is hinged with the movable frame; and an cylinder capable of driving the feed template to rotate is fixedly arranged on the movable frame. By utilizing the slopemovable frame and regulating the front and back positions of the movable frame and the lifted angle of the feed template, the invention can meet requirements of the diameter changes of tyre belted drums of different specifications and effectively shorten the length of the feed template so as to prevent the rigidity of the feed template from being reduced due to too long length; since a tension-adjustable roller is arranged to reduce the possibility of generating a gas interlayer in the winding process, the product quality is improved; and the material pouring prevention structure can effectively prevent material pouring phenomena from happening, thus having no restriction on the left and right movement of belted layer materials and improving operational convenience and production efficiency.

Description

technical field [0001] The invention belongs to the technical field of tire machinery, and in particular relates to a belt layer feed rack for a building machine of a giant tire. Background technique [0002] figure 1 Shown is the schematic diagram of the feed rack of the prior art. Such as figure 1 As shown, the feeding frame includes a conveying mechanism 6, a fixed frame 5 and a feeding template. The belt layer material is from figure 1 The conveying mechanism 6 on the right side of the frame is transported to the right side of the fixed frame 5, and the left side of the fixed frame 5 is fixedly provided with a front guide structure 4, which is used to accept the belt layer material conveyed from the conveying structure 6 and move the belt The layers are guided to the feeding template, and the feeding template includes a first feeding template 1, a second feeding template 2 and a third feeding template 3, and the described feeding templates are arranged up and down in...

Problems solved by technology

[0004] The maximum diameter of the tire made by the previous model is within φ2100mm, so the feeding template can adapt to the wrapping requirements of small drums and large drums as long as it swings up and down. However, in the production of giant tires, the tires are larger in size and the diameters of the belt drums are relatively large. Large, the previous form of feeding template cannot be adapted, and there are four unsuitable points:

[0005] 1. In the production of different types of giant tires, the diameter of the belt drum is from φ2000-φ3750mm. If the form of the original feeding frame template is used, the size of the feeding template will be wide and long, and the length of the template should meet the requirements of the small diameter belt drum. requirements, that is, the outflow direction of the belt layer on the feeding template should be tangent to the outer circular surface of the belt drum and the height of the tangent point should be convenient for human operation. When the material outflow direction is tangent to the drum, its tangent point is close to the top of the drum, and it is a three-layer feeding template, which cannot be reached by human hands, and it is difficult to meet the operation requirements;

[0006] 2. When the inclination angle of the feeding template is large, the speed of the belt layer material is not easy to control, and it is easy to make the belt layer material wrapped on the belt drum loose during winding, resulting in air entrainment; When the uppermost template is too steep, the last section of the material slips off before it is wrapped around the belt drum, which leads to the adhesion of the material, which is troublesome to handle and easy to waste;

[0007] 3. On the existing feeding template, the centering of the belt layer material is achieved by manually turning the hand wheel to drive the screw or the hand-pulled rod. It is not very convenient to readjust the material, and the application It is even more inconvenient on giant tires, because the belt materials of giant tires are relatively wide, and it is not feasible to adjust the centering baffle by hand screw or hand;

[0008] 4. In the current conveying mechanism, in order to prevent the belt material from falling back, an anti-dumping mechanism is generally provided, but the existing anti-dumping mechanism operates on the post-centering of the belt layer on the feeding mechanism Cause interference and inconvenient operation, especially in the process of making giant tires
