Problems solved by technology

However, the effect is not ideal in actual use. The main problems are: 1. It needs to be manually adjusted in stages and the accuracy is poor; 2. Because the tension of the spring is limited by the material, the length of the conveyor belt exceeds 10 meters. , due to the increase of friction between the conveyor belt and the heating plate, the tension of the spring on the transmission shaft will be uneven, causing the transmission shaft to slip and affect the uniform speed of the conveyor belt; 3. Since the spring is only a one-way tension, Lack of free adjustment of the parallel displacement of the transmission shaft, so once the offset value of the conveyor belt exceeds the specified range, the entire correction function will be completely invalid

Embodiment Construction

[0012] Such as figure 1 , figure 2 , image 3 In the shown embodiment, the automatic in-position deviation correction system for the loading conveyor belt of the vacuum belt dryer of the present invention includes a deviation correction information collector, a deviation correction cylinder and a computer control system. The deviation correction information collector 5 is arranged on both sides of the loading conveyor belt 2, and is composed of a contactor 18, a displacement detector 19, a sensor 21 and a sensor probe 20. The contactor 18 is kept in contact with the loading conveyor belt 2 by a contactor limit spring 22. belt edge contact. In order to keep the contactor 18 in good contact with the belt edge of the loading conveyor belt 2, the present embodiment sets the contactor guide shaft 14 on the contactor 18, and the contactor guide shaft 14 is placed under the loading conveyor belt 2, so that The contactor maintains good contact with the belt edge of the loaded conv...

Abstract

The invention relates to an automatic on-line correcting system for a conveying belt of a vacuum belt dryer, which comprises correcting info collectors, correcting cylinders and a computer control system. The correcting info collectors are located at both sides of the conveying belt; the correcting cylinders are located at both ends of an adjustable drive shaft of a drive of the conveying belt; the cylinder arms are connected with a slider on which the adjustable drive shaft is installed; the computer control system comprises an electric cabinet and a computer. The correcting info collectors send the deviation signals of the conveying belt to the computer control system, after computer processing, the electric cabinet controls the correcting cylinders to drive the cylinder arms to move, and the adjustable drive shaft moves by the action of the cylinder arms, so that the conveying belt will return to the original position, now the correction completes.

Description

technical field [0001] The invention relates to an in-position deviation correction system for a vacuum belt dryer loading conveyor belt, in particular to an automatic in-position deviation correction system for a vacuum belt dryer loading conveyor belt using computer information processing technology. Background technique [0002] The material conveyor belt of the vacuum belt dryer is a conveying mechanism made of one or more layers of Teflon interwoven belts, which passes the loaded materials successively through each heating area of ​​the dryer at a uniform speed. Due to factors such as temperature, vacuum degree, humidity, conveyor belt length, and weight loss of materials during the drying process, the conveyor belt often deviates from the normal trajectory during the working state, which affects the dryer. Continuous operation may even damage the conveyor belt. [0003] In the past, the form of mechanical deviation correction generally installed a set of springs on th...
