Description

Technical Field

[0001] The utility model relates to the technical field of glue mixing, in particular to a glue mixing and supplying system. Background Art

[0002] New display technologies are iterating competitively. The latest display technologies include OLED, mini-LED, mcro-LED, etc. Among them, liquid crystal displays have become the mainstream display products and key devices in the information age due to their advantages such as being thin and light, low-voltage energy-saving, passive display, no radiation hazard, stable image, and easy to achieve large-area display. Polarizers play an important role in this. A polarizer is usually made by adsorbing dichroic substances (commonly iodine and dichroic dyes) on a polyvinyl alcohol film (PVA film), followed by stretching and drying to form a PVA film, and then bonding (at least one side) an inner protective film (commonly a triacetyl cellulose film TAC film) through an adhesive (glue). Among them, bonding PVA and TAC is one of the important processes, which determines the overall bonding strength, flatness, appearance quality of the polarizer, and affects the weather resistance of the polarizer under extreme conditions. Therefore, the design of the glue supply pipeline and the development of supporting devices are crucial.

[0028] Embodiment 1

[0029] This embodiment introduces a glue mixing and supplying system. Referring to Figure 1 , it includes a glue mixing device and a control terminal. The glue mixing device includes a mixing container and several raw material containers. A mixing assembly is arranged inside the mixing container. The control terminal includes a glue mixing control terminal. The raw material containers are provided with a discharge port, a discharge port solenoid valve, and a weight sensor.

The mixing container is provided with a water inlet, a weight sensor, and a liquid level sensor. The water inlet is connected to the water supply through a pipeline and a water inlet solenoid valve.

The start-stop, rotation speed, and rotation time of the mixing motor are controlled by the glue mixing control terminal. The mixing assembly is fixed inside the mixing container. The mixing assembly can be fixed at the bottom, top, or side wall of the mixing container. When installing the mixing blades in the mixing container, the installation space for each sensor of the subsequent mixing container needs to be reserved.

[0031] The settings of each sensor enable the glue mixing control terminal to obtain the status information inside the mixing container, facilitating the automatic control of the operation of the mixing motor inside the mixing container.

[0032] Reference Figure 1 , this system further includes several glue storage containers. The mixing container is further provided with several glue outlets corresponding to the glue storage containers. The glue outlets are provided with glue outlet solenoid valves. The glue storage containers are respectively connected to the mixing container through glue storage pipelines and the glue outlet solenoid valves. The glue storage containers are respectively provided with liquid level sensors. The glue storage pipelines are respectively provided with glue forming delivery pumps.

[0033] The start / stop, rotation speed, and rotation time of the driving motor of the glue forming delivery pump are controlled by the glue mixing control terminal. The glue mixing control terminal obtains the liquid level information through the feedback information of the liquid level sensor inside the glue storage container. When a glue storage container stores glue up to the specified liquid level, it can control the opening and closing of the glue outlet solenoid valve and switch the pipeline to store glue in another glue storage container.

[0034] Reference Figure 1 , the glue mixing and supplying system further includes a supplying device. The glue storage container is further provided with a supplying port. The control terminal further includes a supplying control terminal. The supplying device includes a supplying port solenoid valve, a supplying pump, and a flow meter that are matched with the supplying port. The glue storage containers are respectively connected to the supplying port through pipelines, the supplying port solenoid valve, the supplying pump, and the flow meter.

[0035] The start / stop, rotation speed, and rotation time of the driving motor of the supplying pump are controlled by the supplying control terminal. The supplying control terminal can adjust the opening degree of the supplying port solenoid valve and the working parameters of the driving motor of the supplying pump by detecting the feedback information of the flow meter to control the supplying flow rate. At the same time, according to the liquid level information obtained by the liquid level sensor of the glue storage container, when the glue storage amount in the currently supplying glue storage container drops to the warning line, the current supplying pipeline is closed and the supplying is switched to another glue storage container.

[0036] Reference Figure 1, the mixing container is provided with a temperature sensor, and the temperature sensor is signal-connected to the glue mixing control terminal. The glue supply device further includes a buffer container, which is used to store the redundant glue output by the glue supply pump when the glue supply control terminal adjusts the opening degree of the glue outlet solenoid valve according to the flowmeter information to control the glue supply flow.

The alarm of the mixing container can receive the signal from the glue mixing control terminal to start and stop the alarm, and the alarm of the glue storage container can receive the signal from the glue supply control terminal to start and stop the alarm. The setting of the alarm makes the alarm combination mode of the whole system richer. In addition to the alarm on the human-machine interface of each control terminal, it can also cooperate with the settings of the alarms of the mixing container and the glue storage container, so that the staff can intuitively understand the specific alarm location.

[0039] Reference Figure 1 , the glue mixing control terminal includes a glue mixing processor and a glue mixing human-machine interface, and the glue supply control terminal includes a glue supply processor and a glue supply human-machine interface. Both the glue mixing processor and the glue supply processor can adopt PLC controllers. Setting the human-machine interface respectively enables the staff to more conveniently understand and control the process of glue mixing and supply, and also makes the automated operation form of glue mixing and supply more diversified. For example, according to different built-in programs, all processes of glue mixing, glue storage, and glue supply can be automatically judged; an alarm can be selected to remind the staff to select a specific glue storage container during the selection stage of the glue storage container, and an alarm can be given to remind the staff to switch the glue storage container when the current glue storage container is full; during the glue supply stage, the staff can select a specific glue storage container for glue supply, and an alarm can be given to remind the staff to switch the glue storage container when the glue storage amount in the current glue supply glue storage container is insufficient.

[0041] Example 2

[0042] Based on the system configuration of the above-mentioned Example 1, this example introduces the specific implementation scenario of the glue mixing and supply system, which specifically includes the following content:

[0043] I. Specific device design:

[0044] Refer to Figure 1 As shown, each raw material container can be set to different sizes according to the required usage. The glue mixing control terminal controls the discharging sequence and discharging amount of each raw material container through the discharging port solenoid valves and weight sensors of each raw material container. In practical applications, the raw material containers are generally arranged above the mixing container to facilitate the transportation of raw materials by gravity. According to the needs of practical applications, raw material transfer pumps can be installed on each connecting pipeline between the raw material container and the mixing container, and the drive motors of the raw material transfer pumps are all signal-connected to the glue mixing control terminal to ensure the transportation effect of the raw materials. For the convenience of device production and assembly, generally, the number of raw material containers does not exceed 5.

[0045] In practical applications, the mixing blades often adopt double-blade type or four-blade type. In practical applications, considering the requirements of the cleanliness and safety of the glue, refer to Figure 1 As shown, the mixing container is generally a sealed container with a maintenance port. The maintenance port is set in the middle of the barrel wall and is set to a size convenient for maintenance. The mixing container is provided with a weight sensor, a liquid level sensor and a temperature sensor. The weight sensor and the temperature sensor are arranged at the bottom of the mixing container, and the liquid level sensor is arranged on the side wall of the mixing container. The diameter of the water supply pipe connected to this system can be set to 100 - 200 mm.

[0046] The glue mixing control terminal can control the solenoid valves of each raw material container. Based on the weight information of the weight sensor and according to the glue formula of the glue mixing control terminal, it automatically opens the solenoid valves of the raw material containers in sequence to supply the set weight and then mixes and makes glue according to the set parameters. The formed glue is automatically selected and filled into the empty glue storage containers. According to the feedback information of the liquid level sensors of each glue storage container, when one empty glue storage container is filled, it switches to another empty glue storage container for storing glue. The above glue mixing steps are all set steps of the glue mixing control terminal and automatically proceed to the next step after meeting the requirements of the previous step. The processor of the glue mixing control terminal can be a PLC controller, and the glue mixing human-machine interface can adopt a display.

[0047] The glue supply control terminal can control the solenoid valves of each glue storage container. Based on the liquid level information of the liquid level sensor and according to the glue supply plan set by the glue supply control terminal, it controls the opening degree of the solenoid valve at the glue supply port of the glue storage container and the working parameters of the glue supply pump to supply glue. After the current glue storage container has finished supplying glue, it switches to another glue storage container to supply glue. The above glue mixing steps are all set steps of the glue supply control terminal and will automatically proceed to the next step after meeting the requirements of the previous step. The processor of the glue supply control terminal can be a PLC controller, and the glue supply human-machine interface can adopt a display.

[0048] The weight sensor of the present utility model can also be replaced by an electronic weighing scale.

[0049] II. Actual application process:

[0050] The glue mixing components used are polyvinyl alcohol powder, bridging agent, and water. The two raw material containers are respectively filled with polyvinyl alcohol powder and bridging agent, and the component ratio is in the ratio of 10:0.5:1400.

[0051] The glue mixing control terminal can obtain the weight information of the raw materials in each raw material container through the feedback information of the weight sensors of the raw material containers, send signals to the solenoid valve at the discharge port of the raw material container filled with polyvinyl alcohol powder raw material, the solenoid valve at the discharge port of the raw material container filled with bridging agent raw material, and the water supply solenoid valve to open the water supply port and the discharge ports of each raw material container in the set order. At the same time, it monitors the weight changes of the raw material containers through the weight sensors of the raw material containers, and obtains the weight information and liquid level information of the mixing container through the weight sensor and liquid level sensor of the mixing container. Until the weights of each raw material container have each decreased by the specified weight and the weight information and liquid level information of the mixing container reach the specified amount, it controls the solenoid valves at the discharge ports of each raw material container and the water supply solenoid valve to close the discharge port and the water supply port respectively.

[0052] The criteria for closing the discharge port and the water supply port are as follows: the weight of the raw material container filled with polyvinyl alcohol powder decreases by 10 kg, the weight of the raw material container filled with bridging agent solution decreases by 0.5 kg, and the water supply port supplies water until the specified liquid level of the mixing container is reached. After the glue mixing raw materials and the water supply in the mixing container meet the standards, the glue mixing control terminal controls the glue mixing.

[0053] This system can be equipped with a steam type heat exchanger pipeline connected to the mixing container to heat the temperature of the mixing container to 80 degrees through the heat exchange of water vapor flow. According to the actual application environment, the present utility model can also adopt other forms to heat or reduce the temperature inside the mixing container.

[0054] When the glue mixing control terminal detects that the temperature sensor, the glue bucket weight sensor, and the liquid level sensor are all working properly, it starts the mixer to work for 7 hours, and the glue production is completed. The glue mixing control terminal selects a suitable glue storage pipeline according to the liquid level information obtained by the liquid level sensors of each glue storage container, and controls the solenoid valve at the glue outlet and the driving motor of the glue forming transfer pump corresponding to the glue storage pipeline to open the glue outlet and start the glue forming transfer pump respectively. The glue forming transfer pump of the glue storage pipeline passes the produced glue through a filter mesh groove with a particle size of 0.6 μm to filter out insoluble impurities, and stores it in the glue storage container connected to the glue storage pipeline for later use. When the liquid level sensor of the glue storage container detects that the stored glue volume reaches the specified liquid level, that is, the glue storage container has stored the specified amount of glue, the glue mixing control terminal controls the solenoid valve at the glue outlet and the driving motor of the glue forming transfer pump of the current glue storage pipeline to close the glue outlet and the glue forming transfer pump respectively. When a glue storage container has reached the specified stored glue volume and the glue forming has not been completely transported, the glue mixing control terminal switches to the glue storage pipeline of another glue storage container that has not reached the specified stored glue volume for storage.

[0055] The above raw material supply and stirring and glue mixing processes can be automatically executed according to the built-in program after the staff set the initial parameters through the human-machine interaction interface of the glue mixing control terminal. The glue mixing control terminal controls the opening and closing of each solenoid valve through the feedback information of each sensor, and automatically realizes glue mixing and switches the glue storage container for storage.

[0056] The glue supply control terminal can receive the flowmeter signal, compare it with the set value, and output a signal to adjust the glue flow rate by controlling the opening of the glue supply port solenoid valve and / or the working parameters of the glue supply transfer pump driving motor. The redundant glue generated during the glue flow rate adjustment is temporarily stored in the buffer container, and the filter element of the buffer container further filters out impurities and bubbles. When the liquid level sensor of the current glue storage container for glue supply detects that the liquid level drops to the warning line, it triggers the alarm of the glue storage container and / or the glue supply control terminal. The glue supply control terminal closes the glue supply port and the glue supply transfer pump of the glue supply pipeline of the current glue storage container, and switches to the glue supply pipeline of another glue storage container for glue supply.

[0057] The above glue supply process can be automatically executed according to the built-in program after the staff set the initial parameters through the human-machine interaction interface of the glue supply control terminal. The glue supply control terminal controls the opening and closing of each solenoid valve through the feedback information of each sensor, and automatically realizes glue supply and switches the glue storage container for glue supply.

[0058] During the working process of the above glue mixing and glue supply system, the specific process can be adjusted according to the built-in program of the control terminal. For example, in addition to fully automatically completing glue supply and glue mixing, it can also automatically complete the process stage by stage in combination with the alarm.

[0059] After the glue mixing is completed, the alarm of the mixing container and / or the human-machine interaction interface of the glue mixing control terminal will alarm to prompt the staff, and the staff can choose whether to store the glue or switch to a specific glue storage container to store the glue; when storing the glue, when the liquid level of the current glue storage container rises to the specified liquid level line, the alarm of the glue storage container and / or the human-machine interaction interface of the glue supply control terminal will alarm to prompt the staff, and the staff can choose whether to stop storing the glue or switch to another glue storage container to store the glue; when supplying the glue, when the liquid level of the current glue supply container drops to the warning line level, the alarm of the glue storage container and / or the human-machine interaction interface of the glue supply control terminal will alarm to prompt the staff, and the staff can choose whether to stop supplying the glue or switch to another glue storage container to supply the glue; before starting each program of the system, the built-in programs of each control terminal will detect whether each sensor and solenoid valve are working properly. If the program cannot be started, the human-machine interaction interface will alarm to prompt the staff to troubleshoot; when mixing, storing or supplying glue, except for the system fault alarm, other alarms will retain the time for manual selection operations within a certain period of time. When the specified alarm duration is reached, the system will automatically select the next operation according to the default process.
