Description

Technical Field

[0001] This utility model relates to the field of unsaturated resin processing technology, and in particular to a two-component structural adhesive mixing device. Background Technology

[0002] In industrial production, adhesives are a commonly used raw material. For ease of pretreatment and handling, adhesives require good flowability and a long curing time. However, once production is complete, the adhesive needs to cure quickly to prevent unnecessary flow and the creation of defective or even scrap products. These are two contradictory requirements, leading to the development of two-component adhesives. When the two different adhesives are not mixed, both have good flowability and a long curing time; however, once mixed, they cure rapidly in a short time.

[0003] Currently, Chinese Patent CN208161966U discloses a two-component glue dispensing machine, comprising: a first component supply device, including a first feed cylinder, a first insulation structure, and a first heating structure; a first component control device, including a first conveying pipe, a first pump body, and a first flow meter; a second component supply device, including a second feed cylinder, a second insulation structure, and a second heating structure; a second component control device, including a second conveying pipe, a second pump body, and a second flow meter; and a two-component mixing device, including a mixing tank, a stirring motor, a stirring paddle, a circulating water cooling structure, and a glue dispensing nozzle. This utility model provides a two-component glue dispensing machine that avoids sedimentation of the first and second components before mixing, ensures uniform mixing of the first and second components, and provides cooling during the mixing process, guaranteeing the quality of glue dispensing from the nozzle. It is simple to operate and ensures the mixing ratio of the first and second components.

[0004] The above-mentioned existing technical solutions have the following drawbacks: they cannot be quantitatively filled and mixed. The method of directly extracting two components for mixing and filling results in poor mixing effect. Mixing requires time, and only by meeting a certain mixing time can a colloid with good mixing quality be obtained. Utility Model Content

[0005] The purpose of this invention is to provide a two-component structural adhesive mixing device to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A two-component structural adhesive mixing device includes an inlet pipe, an outlet pipe, a first mixing tank, and a second mixing tank. The first and second mixing tanks have identical structures. Both the first and second mixing tanks have inlets at their tops and outlets at their bottoms. The inlet pipe includes a main inlet pipe, a first branch pipe, a second branch pipe, and a three-position two-way solenoid valve. One end of the main inlet pipe, the first branch pipe, and the second branch pipe are connected to the three ports of the three-position two-way solenoid valve, respectively. The other end of the first branch pipe is connected to the inlet of the first mixing tank, and the other end of the second branch pipe is connected to the inlet of the second mixing tank. There are two inlet pipes, and both the first and second mixing tanks have two inlets at their tops. The connection structure of the two inlet pipes to the first and second mixing tanks is identical. The two inlet pipes are used to transport materials with different compositions to the interiors of the first and second mixing tanks, respectively.

[0008] The discharge pipeline includes a main discharge pipe, a third branch pipe, and a fourth branch pipe. One end of the third branch pipe is connected to the main discharge pipe, and the other end of the third branch pipe is connected to the discharge port of the first mixing tank. One end of the fourth branch pipe is connected to the main discharge pipe, and the other end of the fourth branch pipe is connected to the discharge port of the second mixing tank. A butterfly valve is installed in the discharge ports of both the first and second mixing tanks.

[0009] By adopting the above technical solution, the cooperation between the three-position two-way solenoid valve and the two feed pipes can achieve the purpose of feeding materials into the first and second mixing tanks respectively. Therefore, when the material in the first mixing tank is finished being mixed and needs to be used, the second mixing tank is in an empty state. At this time, the butterfly valve of the first mixing tank is opened, and the material inside the first mixing tank is taken out through the discharge pipe for use. At the same time, the two-component material is poured into the second mixing tank for mixing. With this setting, when the material in the first mixing tank is completely used up, the material in the second mixing tank has been mixed. At this time, switching the three-position two-way solenoid valve and the butterfly valve can achieve the purpose of uninterrupted material supply, realizing production without stopping the machine. Moreover, the material in the first and second mixing tanks can be quantitatively mixed to achieve the purpose of quantitative filling.

[0010] In a further embodiment, the outer side of the discharge pipe is covered with an electric heating wire and an insulation layer.

[0011] By adopting the above technical solution, the two-component material is easier to solidify after mixing. Therefore, in order to prevent it from solidifying in the discharge pipe after cooling, it is necessary to wrap an electric heat tracing wire around the discharge pipe.

[0012] In a further embodiment, the first mixing tank has a double-layered hollow structure, and an electric heating coil is provided in the interlayer of the first mixing tank.

[0013] By adopting the above technical solution, the temperature of the mixing tank is ensured, and the colloid is prevented from cooling and solidifying during the mixing process.

[0014] In a further embodiment, the first mixing tank includes a tank body and a tank cover, the tank cover being snapped onto the top of the tank body, and a sealing ring installed on the tank cover is provided at the contact point between the tank cover and the tank body.

[0015] By adopting the above technical solution, it is convenient to clean the inside of the tank. When it is necessary to change different structural adhesives, the inside of the tank needs to be cleaned.

[0016] In a further embodiment, a through hole is provided at the bottom center of the can lid, and a bearing is fixedly installed in the through hole. A stirring rod coaxial with the can body is provided inside the can body. The top end of the stirring rod passes through the bearing, and the stirring rod is provided with an extension section extending to the top of the can lid.

[0017] By adopting the above technical solution, a support frame is set at the bottom of the first and second mixing tanks. The first and second mixing tanks are then spaced apart to the left and right. A linear drive guide rail is fixed to the inner top of the support frame. A servo motor is then installed on the moving part of the linear drive guide rail. A specially structured coupling is fitted on the output shaft of the servo motor to drive the rotation of the stirring rod. The extension section of the stirring rod located at the top of the tank cover needs to be set as a rectangular column. A slot is provided on one side of the bottom end of the coupling. The edges of both the slot and the extension section need to be beveled to facilitate guidance.

[0018] In a further embodiment, both the first and second mixing tanks are equipped with temperature sensors.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By cooperating with two feed pipes using a three-position two-way solenoid valve, materials can be fed into the first and second mixing tanks respectively. Therefore, when the material in the first mixing tank is ready for use, the second mixing tank is empty. At this time, the butterfly valve of the first mixing tank is opened, and the material inside the first mixing tank is removed through the discharge pipe for use. Simultaneously, the second mixing tank is filled with a two-component material for mixing. With this setup, when the material in the first mixing tank is completely used up, the material in the second mixing tank has already been mixed. Switching between the three-position two-way solenoid valve and the butterfly valve at this point allows for uninterrupted material supply, enabling production without stopping the machine. Furthermore, the materials in both the first and second mixing tanks can be quantitatively mixed, achieving quantitative filling. Attached Figure Description
