Technical Field
[0001] This utility model relates to the field of resin product processing technology, and in particular to a fully automatic resin color mixing and stirring device. Background Technology
[0002] In the advertising industry, colored resin castings are the core material for high-end signs, 3D illuminated letters, and other products. Their color effect directly determines the visual appeal and brand recognition of advertising products. These products require mixing base resin and specific color pastes in precise proportions to achieve the target color. The customized nature of advertising products and the high requirements for color consistency (such as the uniform presentation of chain brand store signs) make color matching accuracy and mixing uniformity crucial. Colored resin preparation must meet two core requirements: First, the ratio error between color paste and resin must be ≤±2%, otherwise it will lead to visible color differences in the same batch of products. Second, the color paste must be completely dispersed in the resin to avoid forming "color blocks." Dark-colored products, in particular, have even stricter requirements for dispersion uniformity, as any flaws will significantly affect the visual effect.
[0003] However, existing resin color mixing and stirring devices are insufficient to meet the sophisticated needs of the advertising industry. On the one hand, poor color matching accuracy leads to significant batch color differences. The traditional method of manually weighing color paste is affected by factors such as operator experience, the tendency of high-concentration color paste to agglomerate and leave residues, and uneven color paste sedimentation concentration. This results in large single-batch errors, causing significant color differences in signs within the same batch. Additional manual color adjustment is required to correct these differences, increasing costs and wasting raw materials. On the other hand, the coordination between color matching and stirring is insufficient. Existing devices are mostly separate processes of "manual color matching followed by mechanical stirring." Furthermore, the shear force of the single-axis straight blade stirring structure is insufficient, leading to uneven dispersion of color paste. In particular, dark colors, due to the small amount of color paste added and high concentration, are prone to forming localized overly concentrated "color lumps," which damage the visual consistency of the finished product and reduce the pass rate.
[0004] Therefore, a fully automatic resin color mixing and stirring device is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a fully automatic resin color mixing and stirring device that can solve the problem that existing resin color mixing and stirring devices cannot meet the refined needs of the advertising industry. On the one hand, poor color matching accuracy leads to significant batch color differences. The traditional method of relying on manual weighing of color paste is affected by factors such as operator experience, the tendency of high-concentration color paste to agglomerate and produce "wall-hanging" residue, and uneven color paste sedimentation concentration. This results in large single-time errors, causing significant color differences in signs within the same batch. Additional manual color adjustment is required to correct these differences, increasing costs and wasting raw materials. On the other hand, the coordination between color matching and stirring is insufficient. Existing devices are mostly separate processes of "manual color matching first, then mechanical stirring," and the shear force of the single-axis straight blade stirring structure is insufficient, resulting in uneven dispersion of color paste. In particular, dark colors, due to the small amount of color paste added and the high concentration, are prone to forming localized overly concentrated "color blocks," which damages the visual consistency of the finished product and reduces the pass rate.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic resin color mixing and stirring device, comprising a mixing tank, a constant temperature heating jacket provided on the outside of the mixing tank, a controller provided on the front side of the top of the mixing tank, a dispensing component provided on the top of the mixing tank, a bidirectional stirring structure provided inside the mixing tank, and a color measuring structure provided on the front side of the top of the mixing tank.

A bracket is welded to the right side of the top of the mixing tank, and several color paste metering tanks are evenly welded to the inner side of the bracket. A liquid level sensor is installed at the bottom of the front side of each color paste metering tank, with the sensing end of the liquid level sensor located inside the color paste metering tank. A discharge pipe is connected to the bottom of each color paste metering tank, and a metering valve is connected to the bottom of the discharge pipe. The bottom of the metering valve is connected to the top of the mixing tank. The metering valve is an electromagnetic proportional valve with a flow accuracy of ±0.1 ml / min.
[0008] Preferably, the bidirectional stirring structure includes a motor bolted to the top of the stirring tank, the motor being electrically connected to the controller, and a central gear being fixedly connected to the output end of the motor.
[0009] Preferably, the front and rear sides of the top of the mixing tank are rotatably connected to side gears, which mesh with the central gear.
[0010] Preferably, the bottom of the side gear is fixedly connected to a shaft, which is located on the front and rear sides inside the mixing tank. A spiral stirring blade is provided on the outer side of the shaft, and the front spiral stirring blade rotates in the opposite direction to the rear spiral stirring blade.
[0011] Preferably, the colorimetric structure includes a transparent observation window embedded in the front of the top of the mixing tank, and a hanging sleeve is welded to the top of the front of the mixing tank.
[0012] Preferably, a colorimetric sensor is installed inside the hanging sleeve. The colorimetric sensor is located at the top of the transparent observation window and is electrically connected to the controller, which can provide real-time feedback on the color difference value of the mixture.
[0013] Preferably, the bottom of the mixing tank is provided with a frame, the inside of the frame is a cavity, and the bottom of the mixing tank is connected to a discharge valve, which is electrically connected to the controller.

[0015] Preferably, the constant temperature heating jacket is electrically connected to the controller, and the inner side of the constant temperature heating jacket is provided with a temperature sensing element, with a heating temperature range of 20-60℃ and a temperature control accuracy of ±1℃.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This application sets up a constant temperature heating jacket, a dispensing component, and a two-way stirring structure. In the dispensing component, the flow valve of the resin hopper can accurately control the amount of base resin fed in. The color paste metering tank fixed by the bracket is connected to a quantitative valve (electromagnetic proportional valve, accuracy ±0.1ml / min) through the bottom liquid pipe. With the help of the liquid level sensor in the tank to monitor the remaining amount in real time, the color paste can be automatically quantitatively added, completely eliminating the dependence on manual weighing. This eliminates the error caused by color paste agglomeration, wall adhesion, and uneven concentration due to sedimentation from the source, and strictly controls the proportioning accuracy within ±2%. This effectively avoids batch color difference. The two-way stirring structure enhances the shear force and, combined with the constant temperature heating jacket, reduces the resin viscosity, which can efficiently disperse color paste agglomerates, completely solve the problem of dark "color blocks", and significantly improve the mixing uniformity.
[0018] 2. This application, by setting up a color measuring structure, can monitor the color state of the mixture in the mixing tank in real time. The data is synchronized to the controller to form a closed-loop control. When the color difference exceeds the limit, it can automatically instruct the quantitative valve of the corresponding color paste metering tank to make a micro-adjustment, further ensuring the color matching accuracy, ensuring the color consistency of the finished product, meeting the high requirements of the advertising industry for the color stability of customized products, and reducing the cost of manual remediation and material waste.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-5 The present invention provides the following technical solution:
[0027] A fully automatic resin color mixing and stirring device includes a mixing tank 1, a constant temperature heating jacket 2 is provided on the outside of the mixing tank 1, a controller 3 is provided on the front side of the top of the mixing tank 1, a dispensing component 4 is provided on the top of the mixing tank 1, a bidirectional stirring structure 5 is provided inside the mixing tank 1, and a color measuring structure 6 is provided on the front side of the top of the mixing tank 1.
[0028] The batching assembly 4 includes a flow valve 41 connected to the top left side of the mixing tank 1. The top of the flow valve 41 is connected to a resin hopper 42. A bracket 43 is welded to the right side of the top of the mixing tank 1. Several color paste metering tanks 44 are uniformly welded to the inner side of the bracket 43. A liquid level sensor 45 is installed at the bottom of the front side of the color paste metering tank 44. The sensing end of the liquid level sensor 45 is located inside the color paste metering tank 44. A down pipe 46 is connected to the bottom of the color paste metering tank 44. A metering valve 47 is connected to the bottom of the down pipe 46. The bottom of the metering valve 47 is connected to the top of the mixing tank 1. The metering valve 47 is an electromagnetic proportional valve with a flow accuracy of ±0.1 ml / min.
[0029] In this embodiment: by setting up a mixing tank 1, a constant temperature heating jacket 2, a controller 3, a dispensing component 4, a bidirectional stirring structure 5, and a color measuring structure 6, during operation, the controller 3 first starts the dispensing component 4 according to the preset color mixing scheme. The base resin in the resin hopper 42 is injected into the mixing tank 1 through the flow valve 41 with precise control of the feed amount. At the same time, the color paste metering tank 44 fixed by the bracket 43 adds color paste proportionally through the quantitative valve 47 (electromagnetic proportional valve, accuracy ±0.1ml / min) connected to the bottom liquid pipe 46. The liquid level sensor 45 in the tank monitors the remaining color paste in real time and feeds the data back to the controller 3 to ensure accurate addition. This completely replaces manual weighing and avoids errors caused by color paste agglomeration, wall adhesion, and sedimentation from the source. After the resin and color paste are injected, the controller 3 starts the bidirectional stirring structure 5 to mix the liquid. Stirring is performed while the constant temperature heating jacket 2 is turned on to reduce the viscosity of the resin and enhance the fluidity of the color paste. The bidirectional stirring structure 5 enhances the shear force and efficiently breaks up the color paste agglomerates. Especially for dark color pastes, it can completely solve the "color block" problem and improve the uniformity of mixing. During the stirring process, the color measuring structure 6 monitors the color status of the mixture in the tank in real time, and the data is transmitted to the controller 3 synchronously. If the color difference exceeds the limit, the controller 3 immediately instructs the quantitative valve 47 of the corresponding color paste metering tank 44 to make a micro-adjustment, forming a closed-loop control. After the color meets the standard, the bidirectional stirring structure 5 and the constant temperature heating jacket 2 stop working, completing the color mixing process. The entire process achieves accurate proportioning, uniform mixing and stable color resin preparation through the automatic linkage of various structures, meeting the stringent requirements of the advertising industry for customized products.
[0030] Specifically, such as Figure 5 As shown, the bidirectional stirring structure 5 includes a motor 51 bolted to the top of the stirring tank 1. The motor 51 is electrically connected to the controller 3, and a central gear 52 is fixedly connected to the output end of the motor 51.
[0031] Specifically, such as Figure 5 As shown, the front and rear sides of the top of the mixing tank 1 are rotatably connected to side gears 53, which mesh with the central gear 52.
[0032] Specifically, such as Figure 5 As shown, a shaft 54 is fixedly connected to the bottom of the side gear 53. The shaft 54 is located on the front and rear sides inside the mixing tank 1. A spiral stirring blade 55 is provided on the outer side of the shaft 54. The front spiral stirring blade 55 and the rear spiral stirring blade 55 rotate in opposite directions.
[0033] In this embodiment: by setting a bidirectional stirring structure 5, after the controller 3 starts the motor 51, the central gear 52 at the output end of the motor 51 synchronously meshes with the front and rear side gears 53, driving the two sets of shafts 54 to rotate in opposite directions in the mixing tank 1. The spiral stirring blades 55 on the outside of the shafts 54 rotate in opposite directions with the shafts 54, forming bidirectional shear convection on the resin and pigment mixture, enhancing the stirring force, and efficiently breaking up pigment agglomerates. Especially for dark-colored high-concentration pigments, it can avoid local "color blocks" and improve the uniformity of mixing.
[0034] Specifically, such as Figure 4 As shown, the colorimetric structure 6 includes a transparent observation window 61 embedded in the front of the top of the mixing tank 1, and a hanging sleeve 62 is welded to the top of the front of the mixing tank 1.
[0035] Specifically, such as Figure 4 As shown, a color sensor 63 is installed inside the hanging sleeve 62. The color sensor 63 is located at the top of the transparent observation window 61. The color sensor 63 is electrically connected to the controller 3 and can provide real-time feedback on the color difference value of the mixed liquid.
[0036] In this embodiment: By setting a colorimetric structure 6, the color of the mixture in the mixing tank 1 can be detected externally through a transparent observation window 61. The colorimetric sensor 63, fixed by a hanging sleeve 62, faces the observation window. When working, it emits detection light covering the visible light band. The light passes through the observation window and shines on the surface of the mixture. After reflection, it passes through the transparent observation window 61 again and is received by the colorimetric sensor 63. The colorimetric sensor 63 analyzes the wavelength and intensity of the reflected light and converts it into CIELab color space parameters (including brightness, red-green difference, and yellow-blue difference). It calculates the current color difference value in real time and transmits it to the controller 3. It compares the value with the preset standard value. If the value exceeds the preset range, the controller 3 immediately activates the quantitative valve 47 to replenish the color paste, forming a real-time closed-loop control to ensure color accuracy.
[0037] Specifically, such as Figure 1 As shown, a frame 7 is provided at the bottom of the mixing tank 1. The inside of the frame 7 is a cavity. A discharge valve 8 is connected to the bottom of the mixing tank 1. The discharge valve 8 is electrically connected to the controller 3.
[0038] Specifically, such as Figure 5 As shown, a protective mesh frame 9 is provided on the top of the mixing tank 1, and the protective mesh frame 9 is located outside the central gear 52 and the side gear 53.
[0039] In this embodiment: by setting up a frame 7, a discharge valve 8 and a protective mesh frame 9, the cavity structure of the frame 7 provides installation space for the discharge valve 8, the controller 3 can control the discharge valve 8 to open, and accurately discharge the mixed resin. The protective mesh frame 9 covers the central gear 52 and the side gear 53 to prevent foreign objects from being rolled into the gear set during stirring, and at the same time avoids the operator from contacting the rotating parts, thus improving the safety of the device operation.
[0040] Specifically, such as Figure 1 As shown, the constant temperature heating jacket 2 is electrically connected to the controller 3. The inner side of the constant temperature heating jacket 2 is provided with a temperature sensing element, and its heating temperature range is 20-60℃ with a temperature control accuracy of ±1℃.
[0041] In this embodiment: by setting a constant temperature heating jacket 2, the temperature sensing element inside monitors its temperature in real time and transmits it to the controller 3. The controller 3 adjusts the heating power according to the resin type to achieve a temperature control accuracy of ±1℃ within the range of 20-60℃. By reducing the resin viscosity, the fluidity of the color paste is enhanced. Combined with the bidirectional stirring structure 5, the dispersion of the color paste is accelerated. It is especially effective for high viscosity resins, shortening the stirring time while improving the mixing uniformity.
[0042] Working Principle: When using the fully automatic resin color mixing and stirring device, the operator first presets the target color scheme through the controller 3. The controller 3 then starts the mixing process: the base resin in the resin hopper 42 is precisely injected into the mixing tank 1 through the flow valve 41, while the color paste metering tank 44, fixed by the bracket 43, adds color paste proportionally through the metering valve 47 (electromagnetic proportional valve, accuracy ±0.1ml / min) connected to the bottom liquid pipe 46. The liquid level sensor 45 in the tank monitors the remaining color paste in real time and feeds it back to the controller 3 to ensure the resin and color paste are properly balanced. The initial mixing ratio is precise, completely replacing manual weighing and avoiding errors caused by pigment agglomeration, wall adhesion, and sedimentation from the source. After the ingredients are mixed, the controller 3 simultaneously starts the bidirectional stirring structure 5 and the constant temperature heating jacket 2: the motor 51 drives the central gear 52 at the output end to rotate, meshing with the side gears 53 on the front and rear sides, causing the two sets of shafts 54 to rotate in opposite directions inside the mixing tank 1. The spiral stirring blades 55 on the outside of the shafts 54 rotate in the opposite direction with the shafts 54, forming bidirectional shear convection on the mixture. At the same time, under the monitoring of the temperature sensing element, the constant temperature heating jacket 2 adjusts the temperature precisely according to the resin type. The temperature is precisely controlled between 20-60℃ (temperature control accuracy ±1℃) to reduce resin viscosity and enhance pigment fluidity. The combination of these two methods effectively disperses pigment agglomerates, particularly addressing the issue of dark pigments easily forming "color blocks," thus improving mixing uniformity. During stirring, the colorimetric structure 6 continuously operates: a transparent observation window 61 provides a channel for detection, and a colorimetric sensor 63, fixed by a sleeve 62, faces the transparent observation window 61, capturing the color information of the mixture in real time and converting it into a color difference value, which is then fed back to the controller 3. If the color exceeds the preset range, the controller 3 immediately instructs the corresponding pigment metering tank 44... The quantitative valve 47 performs micro-adjustment to form a closed-loop control. After the color meets the standard, the controller 3 closes the bidirectional stirring structure 5 and the constant temperature heating jacket 2, and at the same time opens the discharge valve 8 at the bottom of the mixing tank 1 to discharge the mixed resin for use. During the entire mixing process, the protective mesh frame 9 at the top covers the central gear 52 and the side gear 53 to prevent foreign objects from being drawn in or personnel from contacting the rotating parts, ensuring safe operation. The entire process achieves precise proportioning, uniform mixing and stable color control of colored resin through the automatic linkage of various structures, meeting the stringent requirements of the advertising industry for customized products.
[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
