Production line of warm edge spacing bar

Abstract

The invention discloses a production line of a warm edge spacing bar. The production line of the warm edge spacing bar comprises an uncoiler and a traction device; the uncoiler comprises a first rack;a central shaft and a support mechanism are arranged on the first rack; the support mechanism is arranged at one end of the central shaft; the uncoiler also comprises a front driving roller, a rear driving roller and a synchronous brake mechanism; a coiled metal sheet is placed above the middle of the front driving roller and the rear driving roller; the central shaft is in sliding fit with the first rack along the vertical direction; the synchronous brake mechanism comprises a brake wheel, a brake belt and a cantilever; the brake wheel is fixedly arranged on the central shaft; the cantileveris rotatably connected with the first rack; the fulcrum of the cantilever is positioned above the brake wheel; one end of the brake belt is fixed on the first rack, and the other end of the brake belt is fixed at one end of the cantilever; the brake belt is wound around the brake wheel from the lower part of the brake wheel; and a guide wheel is arranged at the other opposite end of the cantilever. According to the production line of the warm edge spacing bar, the problem that the coiled metal sheet is easy to loosen when the traction device of the existing production line of the warm edge spacing bar is in a sudden stop.

Description

technical field [0001] The invention relates to the technical field of warm edge spacer production devices, in particular to a warm edge spacer production line. Background technique [0002] The warm edge spacer is a cavity composed of heat insulation strips and stainless steel frames, which is used to fill desiccant, isolate the original insulating glass, and play a supporting role. It is used between double-layer glass to play a role in heat preservation and cooling The warm edge spacer production line is a complete production line for the production of warm edge spacers. [0003] The existing warm-edge spacer production line usually adopts the following method for feeding: set the coiled metal sheet on the unwinding reel, and the traction device in the subsequent process pulls one end of the metal sheet to move, so that the coiled metal sheet on the unwinding reel The metal sheet is rotated to realize the feeding of the metal sheet. With this method, there are the follo...

AI Technical Summary

Problems solved by technology

With this method, there are the following problems: it is loaded through the traction device in the subsequent process. When the traction device stops suddenly, the unwinding reel will continue to rotate due to inertia, which will cause the disc-mounted metal sheet to become loose, and it needs to be loosened. The metal sheets are rearranged into disk shapes, which reduces work efficiency, and even the metal sheets may be placed on the ground, causing damage to the metal sheets, resulting in the need to replace the entire disk-mounted metal sheets, which wastes materials and reduces The work efficiency of the whole production line

Although the utility model has prevented the disk-mounted metal sheet from becoming loose in the working process to a certain extent through the cooperation of the frequency conversion motor and the traction device, the following problems still exist: 1) along with the reduction of the metal sheet in the disk-mounted metal sheet, the same The feeding speed of the disk-mounted metal sheet will become slower and slower, so if you want to control the servo motor to make the feeding speed of the disk-mounted metal sheet consistent with the pulling speed of the metal sheet by the traction device, the servo motor needs to be changed all the time. Speed, servo motors are easy to damage and need to be repaired or replaced frequently, but the maintenance cost, maintenance difficulty and replacement cost of servo motors are far higher than ordinary motors, and the relatively frequent maintenance and replacement of servo motors reduces the warm edge spacer production line. Work efficiency; 2) Although the utility model bypasses the left tension roller, the lower tension roller and the right tension roller successively through the metal sheet, the metal sheet is straightened and corrected, which improves the flatness of its surface and improves the follow-up The effect of metal sheet pressing and forming, but due to the large and fixed height difference between the lower tension roller and the left tension roller, it will cause the metal sheet to go around the left tension roller, the lower tension roller and the right tension roller Time-consuming and labor-intensive, on the other hand, the left tension roller, the lower tension roller and the right tension roller will not play a significant role in preventing the coiled metal sheet from becoming loose and preventing the metal sheet from being placed on the ground
