Problems solved by technology

The biggest advantage of such a joint is high production efficiency, but there are many disadvantages: (1), the contact area between the glue and the glue of the tire tube joint is small, and the contact area is the section perimeter × the thickness of the tire tube (about 2mm)
(2) The two sides of the tire tube are the weak links of the butt joint. Due to the small clamping force of the joint machine clamp on both sides of the tire tube, the butt joint force on both sides of the tire tube is smaller than other places during the butt joint, and the joint strength on both sides is low when the joint is detected. in other parts
(3) The joint effect is affected by the working state and accessories of the joint machine. If the joint machine is not adjusted to the best working condition, the aging and wear of the rubber on the die plate will directly affect the joint effect, and the quality of the joint will be affected.
(4) Since the joint machine is mechanically controlled, it is prone to safety accidents

Embodiment Construction

[0009] The inner tube production process is as follows:

[0010] After batching→banbury→open refining→filtering→sulfurization→extrusion→fixing length→slope cutting→polishing→socketing→compacting→vulcanization→the finished product is made. Among them, batching → banburying → refining → filtering → adding sulfonation → extrusion → vulcanization process is the existing technology, fixed length → slope cutting → grinding → socketing → compaction process:

[0011] The socketing in the tire inner tube production process is completed through the tire tube length fixing 1, slope cutting 2, grinding 3, socketing 4 and compaction 5 processes.

[0012] 1. Fixed length, according to the design length requirements, the tire tube is cut to a fixed length;

[0013] 2. Slope cutting, use a slope cutting machine to cut both sides of the tire tube into slopes with complementary angles;

[0014] 3. Grinding, grinding the cut slope into a rough surface on the grinding machine;

[0015] 4. Sock...

Abstract

The invention relates to the butyl inner tire joint cup jointing method. The cup jointing is completed through the processes of tier cylinder length fixing, slope cutting, grinding, cup jointing, and firm pressing. The tier can resist stretch, with excellent shock resistant value, high in productivity, firm in joint, and durable. It applies to the making of wheel inner tier.

Description

technical field [0001] The invention proposes a butyl rubber inner tube joint socketing method for wheel tires in the field of rubber product manufacturing. Background technique [0002] Before the present invention proposes, inner tube joint has two kinds of joint forms: [0003] 1. The most original inner tube joints are completely done by hand. In order to increase the strength of the joints, people also use to increase the contact area of ​​the butt joint, that is, the tire tube is cut at an angle of 45 degrees with an electric heating knife, and then the cut faces are joined, which increases the contact area. However, due to the low pressure of manual drying and low joint strength, this method is only suitable for the production of natural rubber inner tubes, and the production efficiency is low. [0004] 2. Use a mechanical joint machine. Steps: ① Manually pass the tire tube through the double arms of the splicing machine and place both ends in the flat template so t...
