[0027] In the description of this utility model, it should be understood that the use of terms such as "first" and "second" to define the components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this utility model.
[0028] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0029] Please see the appendix Figure 1-4A batching device for a polyvinyl acetal resin film production line includes a storage tank 1, a preparation tank 2, a finished product tank 3, and a control system 4. The storage tank 1 conveys materials to the preparation tank 2 via a first conveying system 5, and the preparation tank 2 conveys the prepared finished material to the finished product tank 3 via a second conveying system 6.

In this embodiment, it is understood that the redundant automation interfaces are matched with the first and second redundant interface systems; and during the automation upgrade process, there is no impact on the existing production line, and no downtime is required.
[0031] Please see Figure 1 A batching device for a polyvinyl acetal resin film production line includes two storage tanks, one for storing polyvinyl acetal resin material (prepared by dissolving polyvinyl acetal resin powder in a solvent, typically water) and the other for storing a plasticizer (typically a liquid plasticizer). To improve the dissolution rate of the polyvinyl acetal resin or the flowability of the polyvinyl acetal resin material and the plasticizer, the storage tanks may be equipped with heating devices and / or stirring devices. The heating and stirring devices within the storage tanks are controlled by a control system. The two storage tanks supply the polyvinyl acetal material and plasticizer material to the batching tank via a first conveying system, where the two materials are mixed evenly. It should be noted that the two storage tanks can supply materials to the batching tank simultaneously or sequentially. To shorten conveying time and improve efficiency, both storage tanks supply materials to the batching tank simultaneously. The two materials are thoroughly mixed in the batching tank, ultimately forming the finished product, which is then conveyed to the finished product tank via a second conveying system. Redundant interface systems (first redundant interface system and second redundant interface system) are set in both the first conveying system and the second conveying system. When it is necessary to add storage tanks or finished product tanks, or when there is a problem with the storage tanks or finished product tanks, the new equipment can be directly connected without stopping the machine.
[0032] In one specific embodiment, the first conveying system 5 includes a first redundant interface system 51, a first power system 52, a first pipeline 53, and a first interface system 54; the first redundant interface system 51 and the first interface system 54 are respectively disposed in the front half of the first pipeline 53, and the first power system 52 is disposed in the rear half of the first pipeline 53; the storage tank 1 is connected to the first interface system 54, and the preparation tank 2 is connected to the rear end of the first pipeline 53.

That is, the materials in the two storage tanks are transported to the preparation tank through a first power system and a pipeline. At the same time, the first pipeline is equipped with a first redundant interface system to facilitate the addition of new storage tanks, etc.
[0034] In one specific embodiment, the second conveying system 6 includes a second redundant interface system 61, a second power system 62, a second pipeline 63, and a second interface system 64; the second redundant interface system 61 and the second interface system 64 are respectively arranged in the rear half of the second pipeline 63, and the second power system 62 is arranged in the front half of the second pipeline 63; the finished product tank 3 is connected to the second interface system 64, and the preparation tank 2 is connected to the front end of the second pipeline 63.

[0037] Please see Figure 2The control system includes multiple standardized functional control modules. For example, these standardized functional control modules include a power control standard module, an interface control standard module, and a heating control standard module. In actual use, the corresponding module can be directly copied and called using the copy module as needed, avoiding repeated module settings and saving setup time. For an example, please refer to [link to example]. Figure 3 The two first interface systems and two second interface systems can directly use the copy module to copy and call the interface control standard module, and then match it with the corresponding interface system. Similarly, the power control standard module and heating control standard module can be directly copied and called according to actual needs. When it is necessary to add a new storage tank or finished product tank, the copy module can be used to directly copy and call the interface control standard module.
[0038] In one specific embodiment, a liquid level measuring device 11 is provided inside the storage tank 1, and the liquid level measuring device 11 is connected to the control system 4 via a signal connection.

[0043] Please see Figure 3The redundant pump is normally closed, meaning it acts as a standby pump. Under normal operating conditions, the redundant pump will not participate in material pumping; it is only activated when the liquid pump malfunctions and requires maintenance. For ease of maintenance and to ensure uninterrupted production line operation, please refer to [link to relevant documentation]. Figure 4 The liquid pump and the redundant pump are connected in parallel, and valves are installed at the inlet and outlet of both the liquid pump and the redundant pump to facilitate the disconnection of the pipelines containing the liquid pump and the redundant pump during maintenance. The valves can be manual or electronic. The electronic valves can be controlled by the control system to open or close.

The interface control standard module controls the ratio of different materials through the feed rate fed back by the flow meter.
[0046] In one specific embodiment, the preparation tank 2 is also provided with a stirring device 22, which is signal-connected to the control system 4.
