Detailed Description of the Preferred Embodiments

[0019] The technical solution of the present utility model will be further described below through specific embodiments.

[0020] Embodiment

[0021] An automatic clamping mixing mechanism control system includes a control unit, a clamping device and a display. The control unit is electrically connected to the clamping device and the display device. The clamping device is provided with a hydraulic oil tank 1 and a clamping arm 11. The hydraulic oil tank 1 is connected to the clamping arm 11 through an oil inlet pipeline and an oil return pipeline. An oil suction filter 4, a gear pump 6, a check valve 7 and a multi-way solenoid valve 10 are successively arranged on the oil inlet pipeline from the hydraulic oil tank 1 to the clamping arm 11. The oil return pipeline is connected to the multi-way solenoid valve 10.

[0022] The gear pump 6 is connected to the oil pump motor 5.

[0023] An oil suction filter 4 is arranged on the oil inlet pipeline from the hydraulic oil tank 1 to the gear pump 6.

[0024] A pressure gauge 8 is arranged on the oil inlet pipeline from the check valve 7 to the multi-way solenoid valve 10.

[0025] The oil inlet pipeline and the oil return pipeline are connected through a relief valve 9.

[0026] Check valves 7 are arranged on both the oil inlet pipeline and the oil return pipeline from the multi-way solenoid valve 10 to the clamping arm 11.

[0027] A liquid level and liquid temperature gauge 3 is arranged in the hydraulic oil tank 1.

[0028] An air filter 2 is arranged on the clamping device.

[0029] A pressure transmitter 12 is arranged on the oil inlet pipeline.

[0030] The working principle of the present utility model is as follows.

[0031] A control unit, which is used to provide a control signal to control the movement of the automatic clamping mechanism.

[0032] A clamping device, which is connected to the control unit and is used to clamp the cartridge.

[0033] A sensor, which is connected to the control unit, real-time detects the clamping state and mixing state of the material, and feeds back the detection result to the control unit for detecting the clamping state of the cartridge.

[0034] A display, which is connected to the control unit, and displays the clamping state and mixing state in real time for displaying the clamping state of the cartridge, facilitating the operator to monitor and manage the entire control system of the automatic clamping and mixing mechanism.

[0035] As Figure 1 shown, the control unit controls the multi-way solenoid valve 10 and the oil pump motor 5 of the clamping device to work.

[0036] When clamping is required, the oil pump motor 5 in the oil inlet circuit drives the gear pump 6 to work. The hydraulic oil enters the multi-way solenoid valve 10 through the suction oil filter 4, the oil pump motor 5 and the one-way valve 7 in the hydraulic oil tank 1. When the multi-way solenoid valve 10 is controlled by the control unit to be energized and the valve body is opened, the hydraulic oil enters. After passing through another one-way valve 7, the hydraulic oil enters the clamping arm 11 to drive the hydraulic components to perform the clamping work.

[0037] When it is necessary to release the clamping arm 11, the hydraulic oil flows out of the clamping arm 11, flows into the multi-way solenoid valve 10 after passing through the third one-way valve 7 arranged on the oil return circuit. The multi-way solenoid valve 10 is controlled by the control unit to open the valve body, so that the hydraulic oil will flow into the hydraulic oil tank 1 to complete the release work.

[0038] Furthermore, a pressure transmitter 12 is provided to detect the overall oil pressure of the equipment. When it is detected that the equipment pressure is lower than the set pressure, the oil pump motor is started for pressure compensation. When it is detected that the set pressure is reached, the oil pump stops working, and the oil pressure system enters the pressure holding state, and the equipment can perform the lifting and mixing operation. When it is detected that the equipment pressure is excessively higher than the set pressure, the equipment alarms and prohibits the lifting and mixing.

[0039] Among them, the liquid level and liquid temperature gauge 3 is used to monitor the temperature of the hydraulic oil in the hydraulic oil tank 1, and the pressure gauge 8 is used to monitor the pressure of the hydraulic oil in the oil circuit, so as to detect the clamping state of the clamping arm 11. The liquid level and liquid temperature gauge 3 and the pressure gauge 8 are electrically connected to the control unit, and the data is fed back to the control unit, and then transmitted to the display by the control unit to realize the visual operation. The overflow valve 9 is used to control the system pressure, regulate the system pressure and flow rate, and protect the oil pump system, and at the same time has the function of saving energy.

[0040] The above has described in detail an embodiment of the present utility model. However, the above content is only a preferred embodiment of the present utility model and cannot be considered as defining the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of application of the present utility model shall still fall within the scope covered by the patent of the present utility model.
