Abstract
Description
Technical Field
[0001] This utility model relates to the field of epoxy board production technology, specifically to an automatic viscosity control device. Background Technology
[0002] Epoxy resin is a high molecular weight polymer, a product of the condensation polymerization of epichlorohydrin with bisphenol A or polyols. Due to the chemical reactivity of the epoxy groups, epoxy resin can be ring-opened with various compounds containing active hydrogen, curing and cross-linking to form a network structure; therefore, it is a thermosetting resin. Epoxy resin possesses many excellent properties, such as strong adhesion to various materials, especially metals, good chemical corrosion resistance, high mechanical strength, and good electrical insulation. Furthermore, epoxy resin can be cured over a fairly wide temperature range with minimal volume shrinkage during curing. These characteristics make epoxy resin widely used in coatings, adhesives, fiberglass, laminates, electronic casting, and other fields.
[0003] Currently, during the manufacturing process of epoxy resin, it is usually necessary to use a stirring device to stir it in order to enhance the effect of epoxy resin.
[0004] In the above-mentioned solutions, the existing stirring devices are usually not equipped with viscosity adjustment devices. The staff can only measure the viscosity of the epoxy resin and add diluent manually. This is not only time-consuming, but also makes it difficult to accurately control the dosage when adding diluent manually, resulting in the viscosity of the epoxy resin fluctuating and failing to meet the requirements for subsequent use. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic viscosity control device. By incorporating a circulation component and a viscosity adjustment mechanism, the viscosity of epoxy resin can be automatically adjusted, solving the problem that the existing technology requires operators to first test the viscosity of epoxy resin and then manually add diluent, thereby saving a lot of time and ensuring that the viscosity of epoxy resin meets the requirements for subsequent use.
[0006] The solution of this utility model to the aforementioned technical problem is:
[0007] An automatic viscosity control device includes a mixing tank, a feed pipe and a motor fixed at the upper end of the mixing tank, a stirring component provided at the extended end of the motor passing through the mixing tank, a discharge pipe fixed at the lower end of the mixing tank, a circulation component provided on the side wall of the mixing tank, and a viscosity adjustment mechanism provided at the upper end of the mixing tank. The viscosity adjustment mechanism includes a viscometer and a metering addition component, with the viscometer fixed at the upper end of the mixing tank.
[0008] When epoxy resin needs to be stirred, the required amount of epoxy resin is added to the mixing tank through the feed pipe. At the same time, the motor is started to drive the stirring component to rotate, thereby stirring the epoxy resin in the mixing tank. The viscosity of the epoxy resin is monitored in real time by a viscometer. If the viscosity of the epoxy resin is too high, the metering component is activated to add a certain amount of diluent to the mixing tank, thereby precisely controlling the viscosity of the epoxy resin and maintaining it within the required range. Simultaneously, the circulation component is activated to pump the epoxy resin from the lower part of the mixing tank to the upper part, and the epoxy resin is continuously stirred by the stirring component, so that the diluent and epoxy resin are fully mixed, avoiding the problem of the lowest viscosity at the upper part of the mixing tank and the highest viscosity at the lower part, thus not affecting the subsequent use effect of the epoxy resin.
[0009] By incorporating a circulation component and a viscosity adjustment mechanism, the viscosity of the epoxy resin can be automatically adjusted, solving the problem of existing technologies requiring staff to first test the viscosity of the epoxy resin and then manually add diluent. This saves a significant amount of time and ensures that the viscosity of the epoxy resin meets the requirements for subsequent use.
[0010] The utility model is further configured such that: the stirring assembly includes a stirring shaft fixed on the output end of the motor, a stirring frame fixed at the lower end of the stirring shaft, a plurality of first stirring blades fixed on the side wall of the stirring shaft, and a plurality of second stirring blades offset from the first stirring blades fixed on the inner wall of the stirring tank.
[0011] With the above technical solution, when epoxy resin needs to be stirred, the motor is started, which drives the stirring shaft to rotate. The rotation of the stirring shaft drives the stirring frame and multiple first stirring blades to rotate, thereby stirring the epoxy resin. At the same time, by providing multiple second stirring blades, the rotation direction of the epoxy resin during stirring can be changed, increasing the turbulence of the epoxy resin and improving the stirring effect.
[0012] The utility model is further configured such that: the circulation component includes a first circulation pipe fixed to the upper end of the mixing tank, a second circulation pipe fixed to the side wall of the mixing tank, and the ends of the first circulation pipe and the second circulation pipe are equipped with the same circulation pump.
[0013] The above technical solution allows for the pumping of epoxy resin from the bottom of the mixing tank to the top of the mixing tank when the epoxy resin needs to be pumped out through the second circulation pipe and discharged through the first circulation pipe.
[0014] The utility model is further configured such that: the quantitative addition component includes a feeding pipe fixed at the upper end of the mixing tank, and a flow control solenoid valve and a shut-off valve are installed on the side wall of the feeding pipe.
[0015] With the above technical solution, when a certain amount of diluent needs to be added to the mixing tank, the flow control solenoid valve is opened, so that the diluent can be added to the mixing tank. The flow rate of the diluent can be detected by the flow control solenoid valve. When the flow rate of the diluent reaches the required flow rate, the flow control solenoid valve is closed, so that a certain amount of diluent can be added to the mixing tank.
[0016] The utility model is further configured such that a flip-top is rotatably connected to the upper end of the mixing tank.
[0017] With the above technical solution, when it is necessary to observe the stirring of epoxy resin, the staff can open the flip cover to observe the stirring of epoxy resin at any time.
[0018] The beneficial effects of this utility model are:
[0019] Compared with existing technologies, this invention features a circulation component and a viscosity adjustment mechanism, which automatically adjusts the viscosity of the epoxy resin. This solves the problem that existing technologies require staff to test the viscosity of the epoxy resin first and then manually add diluent, thus saving a lot of time and ensuring that the viscosity of the epoxy resin meets the requirements for subsequent use.
[0020] The flip-top design allows for constant monitoring of the epoxy resin mixing process. Attached Figure Description

Detailed Implementation
[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0024] The following is for reference Figure 1 This utility model will now be described.
[0025] An automatic viscosity control device includes a mixing tank 1. A feed pipe 2 and a motor 3 are fixed at the upper end of the mixing tank 1. A stirring component is provided on the extended end of the motor 3 through the mixing tank 1. A discharge pipe 4 is fixed at the lower end of the mixing tank 1. A circulation component is provided on the side wall of the mixing tank 1. A viscosity adjustment mechanism is provided at the upper end of the mixing tank 1. The viscosity adjustment mechanism includes a viscometer 5 and a metering addition component. The viscometer 5 is fixed at the upper end of the mixing tank 1.
[0026] When epoxy resin needs to be stirred, the required amount of epoxy resin is added to the mixing tank 1 through the feed pipe 2. At the same time, the motor 3 is started to drive the stirring component to rotate, thereby stirring the epoxy resin in the mixing tank 1. The viscosity of the epoxy resin is monitored in real time through the viscometer 5. If the viscosity of the epoxy resin is too high, the metering component is activated to add a certain amount of diluent to the mixing tank 1, thereby accurately controlling the viscosity of the epoxy resin and maintaining it within the required range. At the same time, the circulation component is activated to pump the epoxy resin from the lower part of the mixing tank 1 to the upper part of the mixing tank 1. The epoxy resin is continuously stirred by the stirring component, so that the diluent and epoxy resin are fully mixed, avoiding the problem of the lowest viscosity at the upper part of the mixing tank 1 and the highest viscosity at the lower part of the mixing tank 1, thus not affecting the subsequent use effect of the epoxy resin.
[0027] By incorporating a circulation component and a viscosity adjustment mechanism, the viscosity of the epoxy resin can be automatically adjusted, solving the problem of existing technologies requiring staff to first test the viscosity of the epoxy resin and then manually add diluent. This saves a significant amount of time and ensures that the viscosity of the epoxy resin meets the requirements for subsequent use.
[0028] The stirring assembly includes a stirring shaft 6 fixed to the output end of the motor 3, a stirring frame 7 fixed to the lower end of the stirring shaft 6, multiple first stirring blades 8 fixed to the side wall of the stirring shaft 6, and multiple second stirring blades 9 fixed to the inner wall of the stirring tank 1, which are offset from the first stirring blades 8.
[0029] When epoxy resin needs to be stirred, the motor 3 is started, which drives the stirring shaft 6 to rotate. The rotation of the stirring shaft 6 drives the stirring frame 7 and multiple first stirring paddles 8 to rotate, thereby stirring the epoxy resin. At the same time, by providing multiple second stirring paddles 9, the rotation direction of the epoxy resin during stirring can be changed, increasing the turbulence of the epoxy resin and improving the stirring effect.
[0030] The circulation assembly includes a first circulation pipe 10 fixed to the upper end of the mixing tank 1, a second circulation pipe 11 fixed to the side wall of the mixing tank 1, and the same circulation pump 12 installed at the ends of the first circulation pipe 10 and the second circulation pipe 11.
[0031] When it is necessary to pump the epoxy resin from the bottom of the mixing tank 1 to the top of the mixing tank 1, start the circulation pump 12, and pump out the epoxy resin from the bottom of the mixing tank 1 through the second circulation pipe 11 and discharge it through the first circulation pipe 10, thereby pumping the epoxy resin from the bottom of the mixing tank 1 to the top of the mixing tank 1.
[0032] The quantitative addition component includes a feed pipe 13 fixed to the upper end of the mixing tank 1, and a flow control solenoid valve 14 and a shut-off valve 15 are installed on the side wall of the feed pipe 13.
[0033] When a certain amount of diluent needs to be added to the mixing tank 1, the flow control solenoid valve 14 is opened, so that the diluent can be added to the mixing tank 1. The flow rate of the diluent can be detected by the flow control solenoid valve 14. When the flow rate of the diluent reaches the required flow rate, the flow control solenoid valve 14 is closed, so that a certain amount of diluent can be added to the mixing tank 1.
[0034] A flip cover 16 is rotatably connected to the upper end of the mixing tank 1.
[0035] When it is necessary to observe the stirring of epoxy resin, the staff can open the flip cover 16 to observe the stirring of epoxy resin at any time.
[0036] Working principle:
[0037] When epoxy resin needs to be stirred, the required amount of epoxy resin is added to the mixing tank 1 through the feed pipe 2. Simultaneously, the motor 3 is started, driving the stirring shaft 6 to rotate. The rotation of the stirring shaft 6 drives the stirring frame 7 and multiple first stirring paddles 8 to rotate, thus stirring the epoxy resin. Multiple second stirring paddles 9 are also provided to change the rotation direction of the epoxy resin during stirring, increasing the turbulence and improving the stirring effect. The viscosity of the epoxy resin is monitored in real time by a viscometer 5. If the viscosity of the epoxy resin is too high, the flow control solenoid valve 14 is opened, allowing diluent to be added to the mixing tank 1. The flow rate of the diluent can be detected by the flow control solenoid valve 14. When the required flow rate is reached, the flow control solenoid valve 14 is closed, allowing a certain amount of diluent to be added to the mixing tank 1. This enables precise control of the epoxy resin viscosity, maintaining it within the desired range. Simultaneously, the circulation pump 12 is activated, drawing the epoxy resin from the lower part of the mixing tank 1 through the second circulation pipe 11 and discharging it through the first circulation pipe 10. This pumps the epoxy resin from the lower part of the mixing tank 1 to the upper part, where the stirring assembly continuously agitates the resin, ensuring thorough mixing of the diluent and epoxy resin. This prevents the viscosity from being lowest at the upper part of the mixing tank 1 and highest at the lower part, thus ensuring the epoxy resin's subsequent performance.
[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
