On-line pressing device for plastic profiles

Abstract

The invention discloses an online leather strip pressing device of plastic profiles. The online leather strip pressing device comprises a press roller assembly which comprises a driving wheel and a driven wheel; the driving wheel is provided with driving wheel press rollers and driving wheel gears, wherein the driving wheel press rollers and the driving wheel gears are fixedly connected with each other coaxially; the driven wheel is provided with driven wheel press rollers and driven wheel gears, wherein the driven wheel press rollers and the driven wheel gears are fixedly connected with each other coaxially; the outer diameter of the driving wheel press rollers and the outer diameter of the driven wheel press rollers are the same; the transmission of the driving wheel gears and the driven wheel gears is performed through a synchronous toothed belt; the number of the driven wheel gears is larger than that of the driving wheel gears. According to the technical scheme of the online leather strip pressing device of the plastic profiles, the production qualification rate of online leather strip penetrating is improved, the quality of leather strips penetrating the profiles is ensured, the operation of operators is convenient, the labor cost input on a production line is reduced, the problems of deformation, cracks and the like of the leather strips in the prior art are solved, the stability of the production line is improved, and the leather strips can penetrate profile clamping grooves stably under the guardless condition.

Description

technical field [0001] The invention belongs to the technical field of thermoforming processing equipment for plastic profiles. More specifically, the invention relates to an online pimping device for plastic profiles. Background technique [0002] Because the on-line pressing device for plastic profiles is the position where the sealing strips are pressed into the profile and need to be worn on the plastic profile production line. A set of synchronous pressure rollers are used at the position where the profile and the leather strip begin to combine, and the leather strip is pressed into the groove of the profile, so as to achieve the function of wearing the leather strip. [0003] Such as figure 1 and figure 2 As shown, the current online pimping device for plastic profiles uses a synchronous wheel as the pressing roller, and the driving wheel 1 and the driven wheel 3 are driven by a toothed belt 2; the number of teeth of the driving wheel 1 and the driven wheel 3 is eq...

AI Technical Summary

Problems solved by technology

The synchronous wheel simply squeezes the leather strip, which easily deforms the leather strip, resulting in poor sealing effect, and even cracks the leather strip, which makes the leather strip useless and wastes the cost of materials;

[0005] 2. It is inconvenient to operate when starting online, and it is necessary for the operator not to leave the site for guarding. Since the leather strap is completely pressed into the slot of the profile, once the pressing fails, the pressure roller will directly press on the slot of the profile to block the slot of the profile. groove, and the leather strap behind cannot be pressed in, which requires the operator to correct it in time, and the labor input cost of the above scheme is relatively high
