Abstract
Description
Technical Field
[0001] The utility model relates to the field of tire production equipment, in particular to a calibration weight positioning device for an internal mixer oil scale. Background Art
[0002] As we all know, when rubber is processed in an internal mixer, different weights of process oil need to be added according to different types of rubber to complete the mixing of the rubber. The stable operation of the weighing system of this process oil is crucial to the quality of the rubber. The weighing sensor, the core component of the weighing system, needs to be calibrated regularly to ensure that the accuracy of the weighing equipment meets the standard. During the oil scale calibration process, the lifting cylinder hook will rotate as the cylinder piston rotates. After the position changes, the hook contacts the weight, which will affect the weighing value, resulting in the risk of rubber quality caused by inaccurate oil scale metering system. Summary of the invention
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a calibration weight positioning device for an internal mixer oil scale to solve the rubber quality risk caused by an inaccurate oil scale metering system.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a calibration weight positioning device for an internal mixer oil scale is provided with an oil scale box, a crossbeam is horizontally fixed on the upper part of the inner cavity of the oil scale box, and the utility model is characterized in that an oil tank is provided in the oil scale box, a calibration cylinder is fixedly installed on the oil tank via a cylinder base, a weight supporting tray is respectively installed on the inner wall of the oil scale box on both sides of the oil tank, a calibration weight is horizontally placed above the weight supporting tray, a grabbing hook and a hook pin are welded together just above the calibration weight and connected to the cylinder piston rod of the calibration cylinder, a weighing sensor is installed on the oil tank and connected and fixed on the crossbeam, an anti-falling bolt connected with the clearance of the oil tank is installed on the crossbeam, an oil inlet valve is provided above the oil tank, an oil outlet valve is provided below the oil tank, a positioning screw is vertically fixed below the outer shell main body of the calibration cylinder, a cylinder piston locking plate is screwed on the lower end of the positioning screw, and the cylinder piston locking plate is sleeved below the threaded limit of the cylinder piston rod.
[0005] The calibration cylinder is provided with a speed regulating switch for adjusting the air flow.
[0006] The beneficial effects of the utility model are that the piston rod is locked in the direction of the screw rod, thereby preventing rotational displacement during the lifting process, not affecting the up and down telescopic action of the cylinder, solving the risk of the hook contacting the valve due to the rotation of the cylinder piston, and solving the risk of rubber quality caused by the inaccurate oil scale metering system.

DETAILED DESCRIPTION
[0011] In the figure, the utility model is provided with an oil scale box 14, a crossbeam 10 is horizontally fixed on the upper part of the inner cavity of the oil scale box 14, an oil tank 17 is arranged in the oil scale box 14, a calibration cylinder 15 is fixedly installed on the oil tank 17 via a cylinder base 7, a weight support tray 1 is respectively installed on the inner wall of the oil scale box 14 on both sides of the oil tank 17, a calibration weight 2 is horizontally placed above the weight support tray 1, a grab hook 3 is welded to a hook pin 4 just above the calibration weight 2 and connected to the cylinder piston rod 16 of the calibration cylinder 15, a weighing sensor 9 is installed on the oil tank 17, and is connected and fixed on the crossbeam 10, and an anti-fall bolt 8 connected with the oil tank 17 with a clearance fit is installed on the crossbeam 10, which is a safety device to prevent the oil tank 17 from falling. An oil inlet valve 12 is provided above the oil tank 17, and an oil outlet valve 13 is provided below the oil tank 17. A positioning screw 5 is vertically fixed below the outer shell body of the verification cylinder 15. The cylinder piston locking piece 11 is mounted below the threaded limit of the cylinder piston rod 16. The cylinder piston locking piece 11 is screwed onto the lower end of the positioning screw 5 to lock the cylinder piston rod 16 in the direction of the positioning screw 5 to prevent rotational displacement during the lifting process without affecting the up and down telescopic action of the cylinder. The verification cylinder 15 is provided with a speed control switch 6 for adjusting the air flow rate, and the speed control switch 6 is used to adjust the lifting speed of the cylinder piston rod 16.
[0012] When in use, the grab hook 3 keeps a certain distance from the calibration weight 2 and cannot touch the calibration weight 2. The oil inlet valve 12 and the oil outlet valve 13 are provided above and below the oil tank 17, which are used for oil bearing measurement and oil discharge and feeding. When the oil scale is calibrated, the calibration cylinder 15 is connected to the medium to rise, and the calibration weight 2 is pulled up to the cylinder stroke range through the grab hook 3. After the weighing value is consistent with the weight value of the weight, the calibration is completed. The calibration cylinder 15 closes the medium drop and slowly drops the calibration weight 2 onto the weight support tray 1. During the descent process, due to the directional limiting effect of the cylinder piston lock plate 11, the contact distance between the grab hook 3 and the calibration weight 2 remains unchanged. The problem of weighing base is avoided, and the risk of rubber quality caused by the inaccurate metering system of the oil scale is solved.
