Description

Foaming furnace entering hemmer

Technical Field

The utility model relates to a leather production line technical field especially relates to a stove hemmer is gone into to foaming furnace.

Background

Artificial leather is a plastic product that looks and feels like leather and can replace it. Usually, the fabric is used as a substrate and coated with synthetic resin and various plastic additives. Mainly comprises three types of PVC artificial leather, PU artificial leather and PU synthetic leather. The processing technology of the artificial leather in the foaming section comprises the following steps: unreeling, feeding a needle plate, preheating, foaming, feeding the needle plate, heating a surface layer, absorbing lines, cooling and shaping, cutting edges and reeling. The opposite side tracker of the needle plate on the existing foaming furnace entering oven generally adopts a photoelectric edge detecting switch. The light emitter of the photoelectric edge-detecting switch emits light to the machine cloth, the machine cloth reflects light to the light sensor, the light sensor senses that the light moves leftwards, and the light sensor does not sense the light and moves rightwards, so that the edge of the machine cloth is tracked, and the edge of the machine cloth is aligned with the needle plate. The light emitted by the illuminator of the photoelectric edge-detecting switch can normally detect the machine cloth with lighter color and higher brightness, but can lose the detection effect on the machine cloth with darker color and lower brightness. Because the light emitted by the light emitter can not reflect to the photoreceptor when reaching the dark machine cloth, the photoreceptor can not sense the light and then can not move rightwards, the edge detection function is lost, and the normal work can not be realized. And the photoreceptor has higher requirement on the environment, can not work normally on a production line with a small amount of dust, and has high failure rate.

Chinese patent application No. CN201220003082.1 discloses an opposite side tracker of a needle plate on a baking oven for a foaming furnace, which comprises a machine table, an edge detector, a machine cloth moving device and a driving motor, wherein the edge detector is fixed on the edge of the machine table inlet, the output end of the edge detector is connected with the driving motor, and the driving motor is connected with the machine cloth moving device; the edge detector comprises an edge detecting box body, a right limiter, a left limiter, a swing rod and a limit switch, wherein the right limiter and the left limiter are fixed in the edge detecting box body; the combination of the two limiting devices, the swing rod and the limiting switch is adopted to control the machine cloth moving device to adjust the position of the machine cloth, the color requirement of the photoelectric edge detector on the machine cloth is overcome, and the aim of aligning the cloth edge of the tracking machine with the needle plate is fulfilled. Although the defects of the photoelectric edge detector are overcome, the edge detector is controlled by mechanical travel switches such as a limit contact and a limit switch, the response speed is low, the precision is poor, mechanical faults are easy to occur, and the fault rate is high.
