Description

Technical Field

[0001] The utility model belongs to the technical field of chemical engineering and relates to an automatic glue mixing batching system. Background Art

[0002] Glue is a common adhesive in modern life. Due to its good viscosity, it is widely used in various industries. For the existing reflective film in the prior art, it is generally bonded by a multi-layer composite material and glue, and the glue required between different layers of composite materials is also different.

[0003] The quality of the glue is a direct factor affecting the bonding quality between layers in the reflective film. For the quality of different glues, the mixing ratio of each raw material forming the glue is of utmost importance. In the traditional process, to ensure the accuracy of the ratio, several raw material barrels are generally prepared for different raw materials. After calculation, the required amount of this raw material for the current processing and production is poured into each barrel. After weighing, the raw materials in each barrel are poured into the glue mixing barrel for mixing.

[0004] However, this processing method is not fully applicable, especially for processing factories with large-scale production. The single usage amount of various raw materials often has a base of several tons or even more than ten tons. First of all, during the entire production process, a large number of workers are required to cooperate in the production and processing work, and the labor cost is relatively high. Secondly, when batching, due to the large amount of raw materials required at one time, the raw material barrels cannot accommodate them at one time, and multiple weighings and pouring into the glue mixing barrel are often required. During the whole process, it is easy to cause errors in the added amount of raw materials, which has a certain impact on the production quality of the glue. Summary of the Invention

[0005] The purpose of the utility model is to provide an automatic glue mixing batching system for the existing problems in the prior art. The technical problem to be solved by the utility model is: how to ensure the production quality of the glue while reducing costs.

[0006] The purpose of the utility model can be realized by the following technical solutions: an automatic glue mixing batching system, including a glue mixing barrel and several storage tanks. It is characterized in that the automatic glue mixing batching system further includes a controller. A pipeline for transporting raw materials is provided between each storage tank and the glue mixing barrel. An electromagnetic valve, a distributor, and a feeding pump are provided on each pipeline. The electromagnetic valve is arranged close to the storage tank, the distributor is arranged close to the glue mixing barrel, and each electromagnetic valve, each distributor, and each feeding pump are connected to the controller through wires.

[0007] The working principle of this automatic glue mixing batching system is as follows: According to the ingredient requirements of the glue to be configured for the raw materials, the corresponding distributors on the pipeline are controlled by the controller to work. At the same time, the solenoid valves and feed pumps on the pipeline for supplying the required glue are controlled by the controller to open. The raw materials in the corresponding storage tanks are input into the glue mixing barrel through these pipelines for mixing. During this process, due to the presetting of the controller, each distributor can correspondingly control the output volume of the raw materials output from each pipeline, so as to achieve the purpose of accurately outputting different types of raw materials, ensure that the proportion of various raw materials mixed in the glue mixing barrel is more accurate, thus avoiding the problem of errors in the ratio in the prior art, ensuring the production quality of the glue, and in the whole production process, whether it is large-scale production or small-scale production, effectively reducing the turnover operation in the production process, achieving the purpose of reducing costs while ensuring clean production.

[0008] In the above automatic glue mixing batching system, an overflow valve parallel to the feed pump is provided on each of the pipelines, and both the input end and the output end of the overflow valve are connected to the pipeline through branch pipes. Through this setting, the overflow valve cooperates with the branch pipes to balance the pressure in each pipeline, so as to ensure the stable pressure in each pipeline and avoid pipeline rupture.

[0009] In the above automatic glue mixing batching system, the solenoid valve is arranged close to the storage tank, and the feed pump is located between the solenoid valve and the distributor.

[0010] In the above automatic glue mixing batching system, an electronic weighing scale is provided at the bottom of the glue mixing barrel, and the electronic weighing scale is connected to the controller through a wire. Through this setting, it can effectively distinguish whether the load capacity of the glue mixing barrel reaches the saturation state, so that the electronic weighing scale can send a signal to the controller, and the controller controls each electromagnetic three-way valve to work to realize the switching of the outlet switch.

[0011] This automatic glue mixing batching system further includes a number of return pipes. The discharge ports of the return pipes are correspondingly connected to the storage tanks. An electromagnetic three-way valve connected to the controller is provided at the discharge port of each pipeline. One of the outlets of each electromagnetic three-way valve is connected to the glue mixing barrel, and the other outlet is connected to the inlet of the return pipe. Through this setting, after accurate quantity control by each distributor, the electromagnetic three-way valve can be controlled by the controller to open one outlet and close the other outlet, so as to realize direct feeding into the glue mixing barrel through the pipeline. When the load capacity of the glue mixing barrel is saturated, the controller can control to close the originally open outlet and open the originally closed outlet. At this time, the raw materials flowing in each pipeline flow back to the corresponding storage tanks through each return pipe. Such a setting can ensure that the raw materials are always in a flowing state, avoid the solidification of some easily solidified raw materials, and ensure that the raw materials can always maintain their original active state.

[0012] Compared with the prior art, the automatic batching system for mixing glue has the following advantages:

[0013] Through the cooperation of the controller with the solenoid valve, the feeding pump, the overflow valve, the distributor, the electromagnetic three-way valve, and the electronic weighing scale, the solenoid valve controls the on-off of the pipeline, the feeding pump speeds up the transportation of raw materials and stabilizes the pressure through the overflow valve. Under the precise distribution of the distributor, each raw material can be input into the glue mixing bucket through one of the outlets of the electromagnetic three-way valve for mixing, and the electronic weighing scale monitors the carrying capacity of the glue mixing bucket in real time. When its carrying capacity is saturated, the controller controls the electromagnetic three-way valve, and each raw material is output through the other outlet of the electromagnetic three-way valve and flows back to the corresponding storage tank through the return pipe.

[0017] The following are specific embodiments of the present invention and in combination with the drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0018] As Figure 1 shown in Figure 2 the automatic batching system for mixing glue includes six storage tanks 2 for storing raw materials and one glue mixing bucket 1. Each storage tank 2 is connected to the glue mixing bucket 1 through a pipeline 4. Specifically for this embodiment, the six storage tanks 2 are respectively used for storing surface layer glue, bead planting glue, bonding glue, glue adjustment, ethyl acetate, and butyl acetate. The automatic batching system for mixing glue further includes a controller 3 and solenoid valves 41 connected to the near-import ends of the respective pipelines 4. Each solenoid valve 41 is connected to the controller 3 through a wire.

[0019] As Figure 1 shown in Figure 2As shown, the automatic glue mixing system also includes an electromagnetic tee 43 connected to the outlet end of each pipeline 4 and six return pipes 5. Each electromagnetic tee 43 is connected to the controller 3 through a wire, and one outlet of each electromagnetic tee 43 is connected to the glue mixing barrel 1, and the other outlet is connected to the corresponding storage tank 2 through the return pipe 5. A distributor 42 arranged near the electromagnetic tee 43 is also connected to each pipeline 4, and each distributor 42 is connected to the controller 3 through a wire.

[0020] like Figure 1 and Figure 2 As shown, a feed pump 44 is connected between the solenoid valve 41 and the distributor 42 on each pipeline 4. Specifically, it can be a centrifugal pump or axial flow pump commonly used in the prior art, and each feed pump 44 is connected to the controller 3 through a wire. At the same time, a branch pipe 45 connected in parallel with the feed pump 44 is provided on each pipeline 4, and an overflow pump is connected to each branch pipe 45, and each overflow pump is connected to the controller 3 through a wire. An electronic metering scale 11 is provided at the bottom of the glue barrel 1, and the electronic metering scale 11 is connected to the controller 3 through a wire.

[0021] It is worth mentioning that the controller 3 described in this embodiment is a PLC controller commonly used in the prior art.

[0022] Working principle: the controller 3 controls the electromagnetic valve 41, the feed pump 44, the overflow valve 451, the distributor 42 and the electromagnetic tee 43 to open, and the electromagnetic valve 41 controls each pipeline 4 to be in a passage state, and the feed pump 44 sucks the raw materials into each pipeline 4 and transports them outward. At this time, in order to ensure the pressure balance in each pipeline 4, the overflow valve 451 works to suck part of the raw materials into the branch pipe 45 and then re-inputs them into the pipeline 4 through the branch pipe 45. After that, through the setting of the controller 3, the distributor 42 on each pipeline 4 can accurately control the output amount of the raw materials output by each pipeline 4 to achieve the effect of accurate proportioning. Finally, each raw material is input into the glue mixing barrel 1 through one of the outlets of each electromagnetic tee 43 for mixing.

[0023] Secondly, during the entire raw material transportation process, the electronic weighing scale 11 at the bottom of the glue barrel 1 can monitor the carrying capacity of the glue barrel 1 in real time and report it to the controller 3 in real time. When its carrying capacity reaches the saturation state, the controller 3 can control each electromagnetic tee 43 to close the originally opened outlet and open the originally closed outlet. At this time, the raw materials output through each distributor 42 are returned to the original storage tank 2 through each electromagnetic tee 43 and each return pipe 5 in turn.

[0024] On the basis of this basic solution, when producing different glues, such as when producing a glue based on plant gum, the controller 3 controls some of the solenoid valves 41 to open and the other part of the solenoid valves 41 to close, so that the pipelines 4 for conveying plant gum, glue mixing, ethyl acetate and butyl acetate are in a through state, and the pipelines 4 for conveying surface layer glue and bonding glue are in an open circuit state. At this time, under the action of the dispenser 3, the plant gum, glue mixing, ethyl acetate and butyl acetate enter the glue mixing tank 1 in different proportions for mixing. Similarly, when producing a glue based on surface layer glue or bonding glue, it is only necessary to correspondingly control some of the solenoid valves 41 to open and the other part of the solenoid valves 41 to close.

Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0026] Although terms such as glue mixing tank 1, electronic weighing scale 11, storage tank 2, controller 3, pipeline 4, solenoid valve 41, dispenser 42, electromagnetic tee 43, feeding pump 44, branch pipe 45, overflow valve 451, return pipe 5 are used more frequently in this article, the possibility of using other terms is not excluded. Using these terms is only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
