Description

TECHNICAL FIELD

[0001] The utility model relates to zip fastener belt processing technical field more specifically, it is a full electric drive zip fastener belt pre-ironing machine with tensile synchronism. BACKGROUND

[0002] Zip fastener belt pre-ironing machine is a kind of equipment specially used for processing zip fastener belt, mainly used to carry out pre-ironing treatment to zip fastener belt before sewing or other processing, and the purpose of pre-ironing treatment is to improve the flexibility of zip fastener belt, make it more flat and stable, facilitate subsequent sewing or processing operation, and solve the problem of easy arching when sewing on clothes.

[0003] Feeding mechanism, baking mechanism, stretching mechanism and clamping mechanism are the main mechanisms arranged on the rack of zip fastener belt pre-ironing machine, the rack has a feeding channel, the feeding mechanism is responsible for conveying the zip fastener belt to be processed along the conveying channel to the stretching mechanism, the zip fastener belt is heated and softened by the baking mechanism during conveying, the stretching mechanism stretches the zip fastener belt moderately by making differential speed, and the zip fastener belt is taken out by the clamping mechanism after stretching.

[0004] The stretching mechanism of traditional zip fastener belt pre-ironing machine is usually composed of four groups of conveying wheel groups, two of the four groups of conveying wheel groups are installed on the left and right sides of the feeding channel, each conveying wheel group corresponds to a motor and a set of transmission wheel group, and each conveying wheel group includes upper and lower wheels arranged oppositely, the upper and lower wheels are driven to rotate by the corresponding motor and transmission wheel group, the zip fastener belt to be stretched is conveyed by the feeding mechanism to the space between the upper and lower wheels of the conveying wheel group, the motor of the two conveying wheel groups near the front on the two sides of the conveying channel has a higher rotating speed than the motor of the two conveying wheel groups at the rear, so as to form a speed difference and stretch the zip fastener belt, in addition, the clamping mechanism is composed of a cylinder and a clamping jaw, the clamping jaw takes out the stretched zip fastener belt under the action of the cylinder.

[0005] The above-mentioned traditional zip fastener belt pre-ironing machine has the following problems, first, each conveying wheel group of the stretching mechanism is a relatively independent system, when stretching the zip fastener belt, the motors included in each conveying wheel group and the conveying wheel group on the other side of the feeding channel must maintain the same rotating speed, but since each conveying wheel group independently corresponds to a motor and a set of transmission wheel group, different transmission wheel groups often have different manufacturing errors and installation errors, and in the running process, the wear of different transmission wheel groups is also different, which will lead to inconsistent transmission ratio, finally, the upper and lower wheels included in each conveying wheel group and the conveying wheel group on the other side of the feeding channel cannot maintain synchronous rotating speed, affecting the stretching effect of the zip fastener belt, secondly, in order to ensure the normal operation of the clamping mechanism, a gas source device needs to be additionally configured to deliver compressed air to the cylinder of the clamping mechanism, and the gas source device also needs to reserve installation space, obviously, it is not applicable in the space-limited or complex layout scene, which will greatly limit the use scene of the whole zip fastener belt pre-ironing machine.
