Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic production equipment, in particular to a glue adjusting system. BACKGROUND

[0002] In the field of traditional coating process, glue preparation is a crucial link, which is directly related to the quality and production efficiency of the final product. However, for a long time, this link mainly relies on manual operation, which has many problems that are difficult to overcome.

[0003] Firstly, manual glue preparation has the problem of inaccurate preparation ratio. Due to the error and uncertainty of manual operation, it is difficult to ensure that the prepared glue can meet the accurate ratio requirement every time. This not only affects the performance and quality stability of the product, but also may lead to waste and cost increase in the production process.

[0004] Secondly, manual glue preparation is low in efficiency and high in labor intensity. In the coating process, glue preparation usually needs to be carried out frequently, and manual operation not only consumes time and effort, but also is prone to errors due to the fatigue and distraction of the operator. This not only reduces the production efficiency, but also increases the labor intensity and health risk of the operator.

[0005] In addition, manual glue preparation is also affected by many factors such as the ability, experience and fatigue state of the operator. The skill level and experience difference of different operators may lead to the difference of preparation results, and the fatigue state of the operator may also affect the accuracy and stability of preparation. These factors make it difficult to ensure the stability and consistency of product quality in the traditional coating process.

[0006] Therefore, how to solve the problems of inaccurate manual glue preparation ratio, low efficiency and influence by operator factors is a problem that needs to be solved by the technical personnel in the field at present. CONTENT OF THE INVENTION

[0007] The purpose of the present application is to provide a glue adjusting system to solve the problem of poor effect of manual glue preparation in the prior art.

[0008] To achieve the above-mentioned purpose / to solve the above-mentioned technical problems, the present application is realized by using the following technical scheme:

[0009] On the one hand, the present application provides a glue adjusting system, comprising:

[0010] A storage tank assembly for storing raw materials, at least comprising a glue storage tank, an EAC storage tank and an additive storage tank, the glue storage tank, the EAC storage tank and the additive storage tank are respectively provided with their own liquid level sensors and flow control valves for controlling the input of each raw material;

[0011] The mixing assembly comprises a mixing tank and a mixing element arranged in the mixing tank for mixing raw materials;

[0012] The conveying assembly is connected between the storage tank assembly and the mixing assembly, and is used for conveying the raw materials stored in the storage tank assembly to the mixing assembly respectively.

[0013] The controller: the signal output end of each liquid level sensor is signal connected with the signal input end of the controller, and the signal output end of the controller is signal connected with the control end of the conveying assembly and the control end of each flow control valve.

[0014] The storage tank assembly is used for storing raw materials, i.e. glue, EAC and additives, and comprises a glue storage tank, an EAC storage tank and an additive storage tank. Each storage tank is provided with a liquid level sensor. The liquid level sensor is a high-precision liquid level sensor, which can accurately monitor the remaining amount of raw materials in real time and ensure timely replenishment. The flow control valve is used to accurately control the conveying amount of raw materials, so as to avoid waste and imbalance of the formula. The mixing tank is used to contain and mix various raw materials, and the mixing element ensures that the raw materials are fully mixed and uniform. The conveying assembly is responsible for conveying the raw materials in the storage tank to the mixing tank.

[0015] In the scheme, the glue, EAC and additives stored in the storage tank assembly are conveyed to the mixing tank in a predetermined proportion under the control of the controller. The glue, EAC and additives are mixed and adjusted in the mixing tank. The liquid level sensor transmits raw material information to the controller in real time. When the raw materials in the storage tank assembly are insufficient, the controller will send a replenishment signal to control the flow control valve to open and guide the raw materials into the storage tank assembly. When the liquid level of the raw materials in the storage assembly reaches the set amount, the controller sends a stop signal to control the flow control valve to close and stop the raw materials from being guided in. This scheme can accurately control the conveying proportion of raw materials, so as to ensure that each kind of raw material can strictly meet the matching requirements, which is crucial for improving the performance and quality stability of products. In addition, through the realization of automatic control, not only the production efficiency is significantly improved, but also the continuous stability of product quality is effectively guaranteed.

[0016] Preferably, the conveying assembly comprises at least three conveying pipelines and cumulative flow meters arranged on the conveying pipelines. The three conveying pipelines are respectively used for connecting the glue storage tank and the mixing tank, the EAC storage tank and the mixing tank, and the additive storage tank and the mixing tank. The cumulative flow meters are used for collecting the cumulative conveying amount of each conveying pipeline. The cumulative flow meters are signal connected with the signal input end of the controller.

[0017] The controller obtains the actual conveying amount of each raw material in real time through the cumulative flow meter. When the actual conveying amount deviates from the preset conveying amount, the deviation in the use of the raw material can be found and quantified in time. The controller can respond quickly and notify the operator to take appropriate corrective measures through an alarm or other means. For example, adjusting the opening of the flow control valve, automatically adjusting the raw material ratio of the subsequent production batch, etc., to ensure the consistency and stability of product quality.

[0018] Preferably, the conveying assembly further comprises a pneumatic pump arranged on the conveying pipeline. The pneumatic pump uses compressed air or other inert gas as a power source to drive the mechanical structure inside the pump body, thereby realizing the conveying of liquid. It has high conveying efficiency and accuracy, and can ensure that the raw materials are accurately conveyed into the mixing tank according to the preset proportion and amount. Moreover, the pneumatic pump also has good adaptability. They can handle various types of liquids, including high-viscosity, corrosive or flammable and explosive raw materials, without damaging the pump body.

[0019] Preferably, the glue adjusting system further comprises a quality detection assembly for detecting the quality of the mixed glue in the mixing tank, the quality detection assembly comprising a viscosity detection element and a solid content detection element. The viscosity detection element and the solid content detection element are respectively connected to the mixing tank.

[0020] Viscosity is an important indicator of the flowability of glue, which directly affects the use effect and application range of glue. In the quality detection assembly of the present scheme, the viscosity detection element can be a viscometer. Solid content refers to the content of solid substances in glue, which also affects the performance and use effect of glue. In the present scheme, the solid content detection element can be a solid content detector.

[0021] Preferably, a glue supply pump is connected to the mixing tank, and the glue supply pump is connected to the coating head.

[0022] The glue supply pump extracts the uniformly mixed glue from the mixing tank and delivers it to the coating head at a stable pressure and flow rate. During the process, the glue supply pump needs to ensure the continuity and uniformity of the glue to avoid problems such as air bubbles, flow interruption or pressure fluctuations during the conveying process. The coating head is used to uniformly coat the glue delivered by the glue supply pump on the target surface. The coating head can be designed in different shapes and sizes, such as strips, dots, sprays, etc., to achieve different coating effects and precision. At the same time, the glue supply pump can also have the function of adjusting the output flow to adapt to different production needs and product quality requirements.

[0023] Preferably, the glue adjusting system further comprises a human-computer interaction interface, which is bidirectionally connected with the controller.

[0024] The operator can input and adjust the process parameters, such as the proportion of glue, mixing time, etc. through the man-machine interface. The setting of these parameters will directly affect the quality and production efficiency of the product. The man-machine interface can display the production state of the system in real time, such as the remaining amount of raw materials, the liquid level of the mixing tank, the running state of the coating head, etc. When the system fails or abnormal conditions occur, the man-machine interface will display alarm information and issue sound or visual alarms to remind the operator to pay attention. It helps the operator to quickly locate the problem and take appropriate measures to avoid production interruption or product quality damage.

[0025] Compared with the prior art, the beneficial effects achieved by the present application are: in the utility model, the raw materials in the storage tank are transported to the mixing tank under the control of the controller according to the preset proportion. In this process, the liquid level sensor collects the raw material state information in real time and feeds it back to the controller. Once the raw material inventory in the storage tank is detected to be insufficient, the controller immediately triggers the material supplement mechanism and realizes timely and appropriate supplement of raw materials by regulating the opening of the flow control valve. In the scheme, the controller accurately controls the delivery amount of each raw material, ensuring that each raw material strictly follows the proportioning requirements, thereby effectively ensuring the stability and consistency of product quality. At the same time, through automatic control, the production efficiency is improved.

[0026] In addition, the utility model realizes real-time acquisition of the actual delivery amount of each raw material through the cumulative flow meter and transmits the data to the controller. Thus, the deviation in the use of raw materials is found and quantified. When the controller detects that the actual delivery amount deviates from the preset delivery amount, it can display warning information or issue an alarm through the man-machine interface. The operator is notified to take appropriate corrective measures. Thus, the consistency and stability of product quality are further consolidated. BRIEF DESCRIPTION OF DRAWINGS
