Embodiment Construction
[0035] The technical scheme of a method for controlling the opening of the discharge valve of the metal detector of the tobacco stem production line in the present invention will be further described in conjunction with the accompanying drawings and the working process.
[0036] The present invention analyzes the feeding conditions of the belt conveyor FB206 and the vibrating conveyor SR114 and its equipment operation status. Since the amplitude and frequency of the vibrating conveyor SR114 are fixed and non-adjustable, its feeding speed is basically fixed, that is, the metal objects are moved from The time T taken from the feed port of the vibrating conveyor to the valve is basically the same. Therefore, it is only necessary to perform an integral calculation on the distance from the metal detector to the outlet of the belt conveyor FB206.

The invention relates to a method for controlling the switching on of a discharge valve of a tobacco stem production line metal detector, in particular relates to a method capable of effectively discharging metal materials detected by the metal detector out of a cut stem processing line in tobacco strip processing production and belongs to the technical field of tobacco machinery. According to the method, a previous conventional fixed delay control manner is changed, the traveling distance of the metal materials is re-calculated by use of an integral operation method, the calculated distance is compared with an actual distance by a control program, and when the metal materials leave a belt and go into a vibrating conveyor and the calculated distance is equal to the actual distance, the delay control is started; the valve is switched on automatically when the delay time reaches a set value, namely, when the metal materials reach the the valve, the valve is switched on accurately by the control program to effectively discharge tobacco stems with the metal materials, and therefore, the metal materials can be prevented from flowing into the next step to damage processing equipment and further affect the product quality. The method for controlling the switching on of the discharge valve of the tobacco stem production line metal detector has the advantages that original equipment does not need to be greatly modified and only corresponding parameters need to be added; the stems mixed with the metal materials can be accurately discharged.
Description
technical field [0001] The invention relates to the technical field of tobacco machinery, in particular to a method for controlling the opening of a discharge valve of a metal detector of a tobacco stem production line. Background technique [0002] The function of the metal detector on the tobacco stem processing line in the silk production is to discharge the detected metal objects mixed in the material by opening the valve on the back-end equipment, so as to ensure the normal and smooth production of the next stem cutting process . The metal detector is installed in the middle of the belt conveyor FB206. The interface device at the discharge end of FB206 is the vibrating conveyor SR114. The discharge valve is set in the middle of the vibrating conveyor SR114. The outlet of the belt conveyor FB206 is connected with the entrance of the vibrating conveyor SR114. In actual production and use, due to the distance between the metal detector and the valve, the conventional way ...
