[0002] Steel wire fabric refers to the tire component covered with rubber on steel wire cord, and the steel wire cord is covered with rubber to be made into steel wire fabric roll on the fabric calender, and the steel wire fabric roll is cut into fabric pieces in different angles and widths on the cutting bed of steel wire fabric cutting machine, and the shape of fabric piece is parallelogram with certain angle and width.

[0003] In order to realize the continuity of tire forming, the small-angle steel wire fabric cutting machine is designed with a joint device, which splices the cut fabric pieces in the direction parallel to the steel wire, and the fabric pieces are connected end to end (flat joint) and then rolled and supplied to the forming machine.

[0004] Before splicing, there are two parts of fabric, one part is already spliced fabric strip, and the other part is fabric piece to be spliced. The splicing process is as follows: the fabric strip on the splicing conveyor belt is in the waiting position, the feed conveyor belt sends the triangular head of the fabric piece to the tail of the fabric strip and aligns it, the splicing wheel of the steel wire fabric splicing mechanism extrudes the two fabric edges and splices them together, and the splicing conveyor belt forwards the spliced fabric strip, while the tail of the fabric strip remains in the splicing position, waiting for the arrival of the next fabric piece.

[0005] The feed conveyor belt and the splicing conveyor belt are both rectangular worktables, the fabric strip stays on the splicing conveyor belt, and the fabric piece is conveyed from the feed conveyor belt, and the feed conveyor belt stops when the head of the fabric piece rushes into the splicing conveyor belt, at this time, the head of the fabric piece is just positioned at the tail of the fabric strip.

[0006] As can be seen, the head of the fabric piece (triangular area) is rushed to the splicing position on the splicing conveyor belt by the inertia of the fabric piece movement, which is the conventional production method of fabric with angle; and the fabric piece is a thin piece with certain viscosity and softness, when the triangular area of the fabric piece is too wide and too long, the sharp corner of the triangular area of the fabric piece cannot be sent to the position due to the resistance of the stationary splicing conveyor belt, the splicing wheel cannot extrude the two edges of the fabric, and the splicing may fail.

[0009] 1. It further comprises a tip auxiliary conveying belt arranged beside the splice conveying belt and parallel to the splice conveying belt, the side of the tip auxiliary conveying belt is opposite to the tip side of the cord piece.

[0010] 2. A power conveying wheel is arranged above the rear end of the tip auxiliary conveying belt and presses the tip auxiliary conveying belt.

[0011] 3. The tip auxiliary conveying belt is a plurality of parallel belts, and a plurality of equidistant isolation columns are arranged between the belts, and each isolation column is controlled to be lifted and lowered.

[0017] The technical scheme of the utility model will be further described in combination with the embodiment shown in the drawings.

[0018] ​The utility model steel wire cord cutting splicing material tip auxiliary conveying device, including splicing conveying belt 1, feed conveying belt 2 and material tip auxiliary conveying belt 3, along the cord conveying direction, splicing conveying belt 1 and feed conveying belt 2 front, back connection and splicing conveying belt 1 right side setting, material tip auxiliary conveying belt 3 is side by side with splicing conveying belt 1 and set up on the left, material tip auxiliary conveying belt 3 with the upper splicing conveying belt 1 of splicing conveying belt 1 is equipped with the oblique cord joint splicing mechanism, the splicing line of cord joint splicing mechanism is L (the splicing angle of L is according to the cutting angle of cord piece 5, and different cutting angles correspond to different oblique angles), feed conveying belt 2 will after cutting bed cutting cord piece 5 to splicing conveying belt 1 and material tip auxiliary conveying belt 3 delivery, the material tip side of cord piece 5 is located in material tip auxiliary conveying belt 3, as Figure 1 Shown.

[0020] The material tip auxiliary conveying belt 3 adopts a design scheme of three belts side by side from left to right, and two rows of equidistant isolation columns 6 are arranged at intervals between the three belts. Equidistant isolation columns 6 are also arranged at intervals between the right side belt and the splicing conveying belt 1. Among the three rows of isolation columns 6, from left to right, each row of isolation columns 6 is arranged in a staggered manner from back to front, and each isolation column 6 is controlled to be raised and lowered separately, as Figure 1 Shown.

[0021] The plurality of belt structures of the material tip auxiliary conveying belt 3 can be provided with isolation columns 6 that are controlled to be raised and lowered between the belts. Corresponding isolation columns 6 can automatically raise and lower to isolate the cord belt 7 from the running material tip auxiliary conveying belt 3 according to the cutting angle of the cord piece 5, so as to avoid the material tip auxiliary conveying belt 3 from driving the cord belt 7 in the waiting position to cause unstable joint quality when the material tip auxiliary conveying belt 3 is running. At the same time, the relative motion friction between the material tip auxiliary conveying belt 3 and the surface of the cord belt 7 can also be avoided to reduce the cord adhesion.
