Apex adhering device

Abstract

The invention discloses an apex bonding device which is simple in structure, easy to operate, easy to replace the bonding plate, and can overcome the defect at the top of the joint of the apex. A lamination disk formed by splicing fan-shaped disks, a lamination position adjustment mechanism, a lamination disk rotation drive mechanism, a material tail cutting mechanism, a lamination wheel assembly and a pressure roller assembly. With the apex laminating device with the structure of the present invention, the laminating disk can be replaced according to the specification and size of the traveler to be laminated. When replacing, start the motor on the fitting position adjustment mechanism to drive the lead screw to rotate, so that the board seat slides out along the linear slide rail, thereby facilitating replacement. After the replacement is completed, the lead screw drives the board seat to slide inward and return to the fitting position. The screw structure is adopted, which is easy to operate, and can effectively avoid the defect of inaccurate positioning of the bonding disc, and improve production efficiency. The apex laminating device with the structure of the present invention adopts the design of two cutting knives, which effectively solves the defect problem at the top of the joint of the apex material head, improves the production process, and improves the output efficiency of the apex hot-sticking and the quality of the finished product .

Description

technical field [0001] The invention relates to the field of laminating bead apex strips, in particular to an apex laminating device. Background technique [0002] The main function of the bead in the tire is to firmly fix the tire on the rim, overcome the stress generated by the internal pressure, the centrifugal force generated at high speed, etc., and ensure the normal driving of the car. The bead is usually composed of steel wire ring, apex, chafer and so on. The apex acts as a filler in the bead. If there is no apex, it may form a dead corner in the bead, which will cause the place to be unpressed and contain air, and also affect the uniform transition of the thickness of the bead, resulting in the The stress concentration in the mouth causes major quality problems such as bubbling and breaking of the mouth. The apex is determined according to the structural design. If the triangular rubber strip is too thick or too thin, it will not be compacted tightly and air will...

Problems solved by technology

The apex acts as a filler in the bead. If there is no apex, it may form a dead corner in the bead, which will cause the place to be unpressed and contain air, and also affect the uniform transition of the thickness of the bead, resulting in the Stress concentration in the mouth causes major quality problems such as bubbling and breaking of the mouth

If the triangular rubber strip is too thick or too thin, it will not be pressed tightly and the air will be hidden in the slit, causing the slit to deform

The size of the apex joint will also cause different quality problems, which will cause early damage to the tire during use

The triangular rubber strip is attached to the periphery of the circular traveler, and the bottom of the rubber strip is in contact with the outer edge of the steel traveler. When the triangle rubber strip travels around the steel traveler and reaches the closed state, the stroke of the bottom of the triangle rubber strip is smaller than that of its top. , due to the elastic effect of the triangle rubber strip itself, when the cutter cuts off the tail of the triangle rubber strip, there will be defects at the top of the head fracture of the rubber strip during the next round of lamination, which will affect the next round of lamination

[0005] Moreover, the bonding mechanism in this system has a complex structure and poor operability, and it is difficult to replace pressure plates of different diameters.

After replacing the pressure plate with different diameters, the apex bonding position is controlled by the cylinder, and it is difficult to control the cylinder process during the operation, resulting in deviation of the bonding position
