The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0027] Since, in the prior art, the crushed raw materials are mixed manually according to a preset ratio to ensure the accurate ratio of various raw materials. Since the amount of cement trial-mixed each time is relatively small, generally not exceeding 500 g for research purposes, manual batching is prone to errors.

[0028] In view of this, the present utility model provides a fully automatic high-throughput cement trial mixing workstation that uses mechanical control to reduce human errors, increase the accuracy of cement trial mixing, and save labor. Refer to the attached Figure 1 , including: a workbench body 1, the bottom of the workbench body 1 is provided with moving wheels for easy movement, and its moving wheels are provided with braking components for easy fixing after moving to a position; the top of the workbench body 1 is provided with a support plane 11, and at least part of the periphery of the support plane 11 is enclosed with an installation area 12. Specifically, the installation area 12 can be an arc arranged around the support plane 11; a weighing part 2, the weighing part 2 is installed on the top of the support plane 11, and a receiving tray 3 is installed on the weighing part 2, and the receiving tray 3 can be made of 304 stainless steel; a feeding mechanism 4, a plurality of feeding mechanisms 4 are installed in the installation area 12 opposite to the receiving tray 3, and the feeding port 41 of the feeding mechanism 4 is located above the receiving tray 3; a control system 5, the control system 5 is electrically connected to the weighing part 2 and the feeding mechanism 4, and a variety of cement formula parameters can be preset in the control system 5. The control system 5 can control each feeding mechanism 4 to discharge materials into the receiving tray 3 according to the trial mixing requirements, and then move the receiving tray 3 away for raw material mixing.

[0029] In an embodiment of the present utility model, the control system 5 is an inputtable computer, and its internal controller can adopt the W-DSP high-stability technology, which can resist the vibration of the weighing platform in more than 98% of the working conditions; adopt the EMC standard to resist electromagnetic interference and increase the accuracy during the blanking process. A variety of combined weight filtering algorithms can be arranged in the controller, the static repeat accuracy can reach one in 500,000, and the dynamic resolution accuracy can reach one in 150,000, which can meet the micro blanking of 0.01. The above configurations are only selections from the prior art and are used to assist the realization of the functions of the present utility model, and should not be construed as a limitation of the technical solution of the present utility model, nor should it be construed as an improvement of the method.

[0030] The control system 5 is provided with a display touch screen 51, a keyboard 52, a mouse 53, a button area 54 and a host. The display touch screen 51, the keyboard 52, the mouse 53 and the button area 54 are all electrically connected to the host. The button area 54 is located above the keyboard 52, and is provided with an emergency stop button, a power button and a start button for convenient manual control. The keyboard is also provided with a color setting or confirmation key, a cancellation or return key, a direction key for setting parameters, etc.

[0031] The weighing part 2 is a weighing sensor connected to the host, and the weighing sensor can be connected to a transmitter. During measurement, according to the preset ratio, multiple channels are blanked in sequence according to a fixed ratio or the amount set manually. Therefore, what the weighing part actually measures each time is the mass of the raw materials falling in each channel. That is, when the first channel is blanked, the weighing sensor measures and feeds back, and then when the second channel is blanked, the weighing sensor measures and feeds back. The control system calculates the difference between the two as the blanking quality of the raw materials in the second channel, and so on.

[0032] In the present utility model, unless otherwise clearly defined and limited, the terms "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0033] In an embodiment of the present utility model, refer to the appendix Figure 2 , each of the feeding mechanisms 4 includes:

[0034] A feeding motor 42, the feeding motor 42 is supported in the installation area 12 through a motor support seat, and its output end is horizontally connected with a discharge screw, and it is electrically connected to the host;

[0035] The storage bin 43 has a discharge bin 44 at its bottom, and the discharge screw is located in the discharge bin 44; the materials in the discharge bin 44 are extruded by the discharge screw to the feeding port 41. The discharge amount in a single storage bin can be changed by driving the speed of the feeding motor and the discharge screw according to the preset value of the control system. The discharge error can be set. For example, when the discharge value is greater than or equal to the set value of 0.5 g, the speed of the feeding motor will slow down. Specifically, it can be "slow addition amount" or "airborne amount" for slow discharge. The specific definitions of "slow addition amount" and "airborne amount" are explained in detail below and can be understood as reducing the discharge speed and controlling the discharge amount.

[0036] Among them, the feeding motor 42 is driven by a high-speed pulse control servo driver.

[0037] In the above embodiment, the storage bin 43 has a sealing cover 45 at its top.

[0038] In another embodiment, a housing is provided in the installation area 12 relative to the feeding mechanism 4. The top of the storage bin 43 is located at the top of the housing, and the feeding port 41 extends out of the housing in the direction of the receiving tray 3 through a discharge channel.

[0039] In each of the above embodiments, the working platform body 1 has a receiving space below, which can be a drawer or a door that can be opened and closed.

[0040] In the present utility model, the display touch screen 51 has multiple working mode setting interfaces, which may include:

[0041] Channel setting interface, allowing setting of upper and lower deviations and addition and subtraction amounts.

[0042] Input / output setting interface, for setting the feeding mechanism, including start, emergency stop, discharging, alarm, etc.

[0043] System setting interface, which can set formula switching delay, fast acceleration, full acceleration, stable time, peeling range, screw stirring start, stirring time, material shortage alarm, manual start of discharging, manual start of screw stirring, etc.

[0044] Weight calibration interface, which can set zero point, calibration weight, sensitivity, zero setting, etc.

[0045] Feeding motor speed setting interface and communication setting interface, etc.

[0046] The feeding of this utility model is completed by controlling the feeding motor. Each storage barrel can hold 2L of raw materials. The storage barrels without the housing shielding scheme can be made of a specific acrylic material, and at the same time, a high-quality 304 stainless steel barrel cover is equipped above to play a sealing role, so that the raw materials in the storage barrel are not easily affected by temperature and humidity. At the same time, the acrylic material of the storage barrel can observe the storage situation of the internal raw materials at any time. When the control system automatically prompts that the material in the barrel is insufficient, the raw materials can be filled in time (the control system subtracts the amount of each discharge from the internal total amount of the storage barrel in turn to know whether there is a shortage of materials). At the same time, the discharge screw can stir the raw materials during the feeding process to facilitate feeding.

[0047] The discharge channel, the discharge bin, and the storage barrel can all be made into a detachable mode (such as bolt and gasket connection), which is convenient for cleaning before adding new materials after one kind of raw material is used up. After disassembly, the discharge screw and the storage barrel can be wiped.

[0048] During the cement trial mixing process, it not only greatly simplifies the work process that testers need to perform manual operations for a long time, but also can automatically feed and weigh according to the settings or formulas. During the feeding process, it can feed quickly or slowly according to the target value of each material and stop discharging when the target weight is reached.

[0049] The control system can store the cement mix ratios of no less than 16 formulas. Under the fixed ratio of the instrument, only the target feeding values of various cement materials need to be input in turn, and then each material can be automatically fed. At the same time, manual control of feeding is also possible, and the materials are discharged according to the ratio set by the R & D personnel. The discharge method controls the corresponding feeding mechanism to discharge through buttons. During the discharging process of the instrument, the screen directly displays the current feeding amounts of various materials. At the same time, when the feeding amount is about to reach the target amount, the controller controls the feeding motor to drive the discharge screw to change the rotation speed according to the specific situation, and slow addition (during the feeding process, if it is measured that the feeding weight ≥ target weight - slow addition amount, then turn off the fast addition and start slow addition), or air amount (during the feeding process, if it is measured that the feeding weight ≥ target weight - air amount, then turn off the slow addition and stop feeding), or slow addition (for example, only 0.5g is put each time) can be realized, which greatly improves the manual measurement error. Set the "upper deviation" and "lower deviation" to control the feeding accuracy, and the system will automatically alarm when the range is exceeded.
