Leather belt grooving apparatus and method

Abstract

The invention relates to a belt slotting device and a belt slotting method, which can improve the manufacturing quality of a belt provided with a slot. The slotting device comprises a slotting cutter which is made of electrically conductive metals, wherein the cutter is connected to a heating transformer, and the heated cutter performs heat slotting operation on the belt; the heating transformer is arranged on a tool bar, and the tool bar is rotatable and connected with a planker which is connected with a transmission screw rod through a transmission nut; the transmission screw rod is arranged on a main cross beam, connected with a motor through a belt pulley and a triangle belt, and driven to rotate, so that the cutter is driven to move transversely along the axial direction of the transmission screw rod; both ends of the main cross beam are arranged on a pair of upright posts through adjusting bolts; lower parts of the upright posts are provided with pulleys; and the pulleys can move vertically on a vertical movable track and drive the cutter to perform vertical movement, so that the continuous slotting is performed backwards. The device and the method for manufacturing the belt provided with the slot by performing continuous slotting on a flat belt are time and labor saving, and not only reduce the manufacturing cost but also improve the manufacturing quality of the belt.

Description

technical field [0001] The invention relates to a device and method for slotting a belt with grooves used in a vacuum belt dehydrator during manufacture. Background technique [0002] The vacuum belt dehydrator is used to separate the water and gypsum in the gypsum slurry produced by the desulfurization of the thermal power plant, and remove the Cl in the gypsum - (chloride ion) a device. The grooved belt in this device is one of its main and most valuable components. [0003] The current processing status of this grooved belt: [0004] Using a special belt slotting device, the ordinary flat belt is processed into a belt with grooves. That is, when the belt is made, the flat belt is pressed and vulcanized using a mold with a boss. [0005] Due to the high manufacturing cost of the mold with the boss, it is impossible to make it very long, so the flat belt can only be pressed and vulcanized in sections to increase the number of times the belt is vulcanized, and the mold m...

Problems solved by technology

[0005] Due to the high manufacturing cost of the mold with the boss, it is impossible to make it very long, so the flat belt can only be pressed and vulcanized in sections to increase the number of times the belt is vulcanized, and the mold must be adjusted each time the next section is vulcanized Boss, needs to match previously vulcanized belt groove

Therefore, this method of making grooved belts is labor-intensive and time-consuming, making it expensive to process

In addition, because the vulcanization length of the flat belt is short each time, it is difficult to guarantee the straightness of the belt, which affects the quality of the belt and ultimately affects the dehydration efficiency of the vacuum belt dehydrator.
