Description

Technical Field

[0001] The present invention relates to the technical field of blanking devices, and particularly relates to a blanking device for manufacturing permeable stones. Background Art

[0002] Permeable stone is the solid form of ecological permeable concrete, which is composed of cement, water, permeable concrete enhancer and high-quality same-size or gap-graded aggregates, and has a certain porosity. Permeable stone has functions such as sound absorption, noise reduction, ecological environmental protection, drainage and anti-slip. The blanking device is a commonly used equipment in the production process of permeable stones. The existing blanking devices generally blank one mold at a time, with low blanking efficiency, and it is easy to cause more material in one mold and less material in another mold during the falling process, resulting in different sizes of the formed permeable stones.

[0006] Further, the blanking mechanism includes a storage tank, a lifting motor and a blanking plate. The storage tank is installed at the upper end of the support frame, the lifting motor is installed below the support frame, the lifting end of the lifting motor is fixedly connected to the blanking plate, a blanking pipe for conveying the raw materials into the blanking plate is arranged between the blanking plate and the storage tank, the upper end of the blanking pipe is communicated with the discharging end of the storage tank, the lower end of the blanking pipe is communicated with the feeding end of the blanking plate, and the lifting motor is connected to the PLC controller;

[0007] Further, a plurality of blanking nozzles for conveying raw materials into the molds are provided on the blanking tray, and each blanking nozzle corresponds to a mold in the mold tray of the mold;

[0008] Further, valves are provided at the connection between the blanking nozzle and the blanking tray, and each valve is an independent individual and is controlled separately by a PLC controller;

[0009] Further, vibrators for preventing the raw materials from being blocked and facilitating the raw materials to be conveyed into the blanking tray through the blanking pipe are provided at the connection between the storage bin and the support frame, and the two vibrators are symmetrically arranged on the left and right at the connection between the storage bin and the support frame;

[0010] Further, a weighing device for monitoring the weight of the storage bin is installed at the upper end of the vibrator, the weighing device is installed between the vibrator and the storage bin, and the weighing device is connected to the PLC controller;

[0011] Further, a weighing device for monitoring the weight of the mold is provided at the bottom of each mold tray, and the weighing device is connected to the PLC controller through a signal.

[0012] Working principle of the present invention:

[0013] The staff pushes the feeding vehicle to the left side of the support seat, and inserts the feeding end of the conveying pump into the feeding vehicle. The staff starts the PLC controller, and the PLC controller controls the vibrator to work. The vibrator generates vibration, and the raw materials in the storage bin are conveyed into the blanking tray along the blanking pipe. At the same time, the PLC controller controls the conveyor belt to convey the empty mold tray to directly below the blanking tray. The PLC controller controls the lifting motor to work, and the lifting end of the lifting motor drives the blanking tray to descend. The blanking tray drives the blanking nozzle to descend to a certain height P. The PLC controller controls the lifting motor to stop descending. The PLC controller controls the valve to open, and the raw materials fall into the mold in the mold tray along the blanking nozzle on the blanking tray. At the same time, the weight of the mold at the bottom of the mold starts to be measured. After the value measured by the weighing device reaches the specified value, the weighing device sends a signal to the PLC controller, and the PLC controller closes the valve on the blanking nozzle above the mold until all the valves on the blanking tray are closed. The PLC controller controls the lifting motor to rise, and the lifting motor drives the blanking tray to rise to the original position. The conveyor belt conveys the mold tray after blanking out, and conveys a new mold tray to directly below the blanking tray.

[0014] During the falling process, the weighing device weighs the storage bin and feeds back the result to the PLC controller. The PLC controller processes the result. Whenever the weight of the storage bin is less than the maximum value of the specified range, the PLC controller controls the conveying pump to work. The conveying pump transports the raw materials in the feeding vehicle to the storage bin until the weight of the storage bin is greater than the maximum value of the specified range. Then the PLC controller controls the conveying pump to stop transporting. Whenever the value feedback by the weighing device remains unchanged for a period of time during the transportation of the conveying pump, the PLC controller sends a signal to the alarm, and the alarm gives an alarm to remind the staff to come and replace the feeding vehicle.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] A blanking device for manufacturing permeable stones includes a mold plate for placing raw materials, a blanking mechanism for transporting the raw materials into the mold plate, a support seat for supporting the blanking mechanism, a conveyor belt for transporting the mold plate, a feeding vehicle for transporting raw materials, a conveying pump for transporting the raw materials in the feeding vehicle into the blanking mechanism, a PLC controller and an alarm. This device automatically transports the raw materials into the mold plate through the PLC controller, without manual feeding, with high automation, fast blanking speed and good blanking effect. It can automatically blank into the mold plate and transport the mold plate to the next process.

[0017] A vibrator is provided at the bottom of the storage bin of this device. The vibrator generates vibration, which can prevent materials from being blocked during the process of being transported through the blanking pipe to the blanking plate, resulting in abnormal blanking of the storage bin.

[0018] A weighing device is provided at the bottom of the storage bin of this device. The weighing device can monitor the weight of the storage bin in real time. When the weight of the storage bin is too light, it can automatically transport the raw materials into the storage bin through the conveying pump without manual feeding. It can automatically transport the raw materials in the feeding vehicle into the storage bin to prevent the shortage of raw materials in the storage bin, which may lead to the inability to blank the raw materials into the mold plate and affect normal production. And when the raw materials in the feeding vehicle are consumed, the alarm can give an alarm in time to remind the staff to go and replace the feeding vehicle. Description of the Drawings
