Problems solved by technology

[0004] After the tread guides into the feeding frame, it will be centered first, so that the centerline of the tread is aligned with the centerline of the belt drum to ensure the quality of bonding. However, after the cutting device, the horizontal cutting method is usually used , tends to shift the centered tread, so that the tread cannot be in the middle when it is attached to the drum, which affects the quality of tire building
[0005] In addition, there may be errors in the length of the tread cut by the length measuring device and the cutting device to the preset value of the system, so that when the tread is wound on the belt drum, the ends cannot be perfectly connected. Affects tire uniformity

Embodiment 1

[0047] Example 1, such as figure 1 As shown, the tire tread feed frame of the present invention includes a frame 1 that plays a role of foundation fixed support, and a delivery formwork 2 for delivering the tread to the belt drum, wherein the delivery formwork 2 includes There are two side frames 3, a conveyor belt 8, and an automatic deviation correction mechanism 4, a cutting mechanism 5, a length measuring mechanism 6, a laminating roller mechanism 7, and a conveyor belt arranged in sequence between the two side frames 3 along the tread conveying direction. 8 is a synchronous belt driven by a servo motor.

[0048] like figure 2 As shown, the cutting mechanism 5 includes a fixed bracket 51 and a swing bracket 52 , and the fixed bracket 51 is fixed on the side frames 3 of the conveying template 2 through the bottom plates 517 on both sides. Swing arms 53 are arranged on both sides of the swing bracket 52 , and the lower ends of the swing arms 53 are pivotally connected wit...

Abstract

A tread feed rack and a feed method thereof of the invention can simultaneously satisfy centering and length control demands for tread materials. In a cutting process, a cutter slides on a sliding track of a cutter carrier by a driving mechanism, and in a process that the cutter slides downwards, the cutter cuts off the tread by a shoveling manner. The cutter carrier of the feed rack is fixed on a frame at two sides of a conveying template, the sliding track is arranged on the cutter carrier, the sliding track forms a certain included angle with the tread conveying direction, and the cutter is slidingly connected with the sliding track. The tread feed rack and feed method thereof of the invention can eliminate the influence on centering in the cutting process, simultaneously eliminates length control error influence on the tyre homogeneity.

Description

technical field [0001] The invention relates to a tread feeding rack used in tire manufacturing and a feeding method thereof, belonging to the field of rubber machinery. Background technique [0002] At present, in the manufacturing process of all-steel radial and semi-steel car tires, it is necessary to transfer the tread to the belt layer bonding drum to realize the bonding of the tread and the belt layer. [0003] The function of the tread feeder is to convey the rolled tread on the I-shaped wheel and attach it to the belt drum. It should mainly meet the following two requirements: 1. Centering, which requires the center of the tread to be in line with the belt drum The circumference of the center line of the belt layer drum coincides; 2. Fixed length, the tread that requires automatic cutting should be completely attached to the belt layer drum, wound around one circle, and the length is just butted, so as to achieve unmanned operation through pressure roller pressing a...
