Embodiment 1

[0027] like Figure 1 to Figure 4 As shown, a turn-up joint device for a thermoplastic elastomer inner tube, the device includes a first inner tube clamp 1, a second inner tube clamp 2, a rotating assembly 3 and a bonding assembly 4; the first inner tube clamp 1 and the second inner tube clamp 2 Each includes a first clamping block 101 and a second clamping block 102, the first clamping block 101 and the second clamping block 102 are provided with an inner tire groove 103, and the two inner tire grooves 103 are connected to form a matching inner tube Ring, through the inner tube groove 103 to facilitate better matching with the inner tube, and improve the stability of the inner tube during the splicing process. The connection end of the first inner tube clamp 1 is connected on the rotating assembly 3, and the rotating assembly 3 includes a rotating motor 31 and a rotating frame 32, and the rotating frame 32 is connected with the rotating shaft of the rotating motor 31, and the...

Embodiment 2

[0033] This embodiment differs from Embodiment 1 only in the adhesive component 4, and other structures and usage methods are the same.

[0034] The bonding assembly 4 of this embodiment is an ultrasonic transmitter, and the ultrasonic head of the ultrasonic transmitter is in an arc shape matching the inner tube. The inner tube is melted and bonded by the ultrasonic transmitter, and the inner tube is better matched by the ultrasonic head. After bonding, the excess turn-up part is cut and removed by ultrasonic waves.

[0035] The inner tube jointing process can be realized through two different methods of ultrasonic transmitter and laser transmitter, which not only improves convenience, but also facilitates the improvement of bonding strength and bonding quality.

[0036] The device facilitates better positioning and fixing of the two ends of the inner tube through the first inner tube clamp 1 and the second inner tube clamp 2, and facilitates better cooperation with the inner...

Abstract

The invention relates to the technical field of tire production and manufacturing, in particular to a thermoplastic elastomer inner tube reverse-wrapping jointing device and method. The device comprises a first inner tube clamp, a second inner tube clamp, a rotating assembly and a bonding assembly, wherein the first inner tube clamp and the second inner tube clamp each comprise a first clamping block and a second clamping block, inner tube grooves are formed in the first clamping blocks and the second clamping blocks, the two inner tube grooves for each inner tube clamp are connected to be matched with an inner tube in shape, the connecting end of the first inner tube clamp is connected to the rotating assembly, the matching end of the first inner tube clamp is matched with the matching end of the second inner tube clamp, inner tubes in the matching end of the first inner tube clamp and the matching end of the second inner tube clamp are bonded to form a bonding face, and the bonding assembly is located on the outer side of the bonding face and used for melting and bonding the bonding face. The device and the method have the advantages of being convenient to operate, increasing theconnection area of the two ends of the inner tube, improving the bonding comprehensiveness and firmness of the two ends of the inner tube, improving the connection strength and prolonging the servicelife.

Description

technical field [0001] The invention relates to the technical field of tire manufacturing, in particular to a turn-up jointing device and jointing method for a thermoplastic elastomer inner tube. Background technique [0002] The tire is mainly composed of a tire, an inner tube, and a pad, and the inner tube is an important part of the tire. The existing inner tube includes a plastic carcass and a plastic valve, such as a plastic valve and an inflatable plastic inner tube with application number 2019212494566. The valve includes a mouth body and a rubber pad; the mouth body is made of hard plastic material, and the mouth There is a vent hole in the middle of the body, and a valve core is arranged in the vent hole; a plum blossom-shaped matching part is provided at the lower end of the mouth body; the rubber pad is made of soft plastic material, and the rubber pad is arranged at the lower end of the mouth body. The outer ring of the pad spreads from the outer ring of the noz...
