Description

Technical Field

[0001] The utility model relates to the technical field of acrylic emulsion preparation, and particularly relates to a raw material proportioning device for acrylic emulsion preparation. Background Technique

[0002] Acrylic emulsion is an aqueous polymer dispersion system copolymerized by acrylate monomers (such as methyl acrylate, ethyl acrylate, butyl acrylate, etc.) through emulsion polymerization technology. Its appearance is milky white or nearly transparent viscous liquid, also known as "pure acrylic emulsion". Acrylic emulsion is mainly applied to fields such as architectural coatings, textile industry, packaging and papermaking, and industrial protection. The preparation of acrylic emulsion requires mixing various raw materials such as acrylate monomers, functional monomers, initiators, emulsifiers, and water in proportion, which requires proportioning various raw materials according to the preparation amount and use of acrylic emulsion.

[0003] In the prior art, when proportioning the raw materials of acrylic emulsion, usually multiple containers with the same mass are used. Different raw materials are poured into each container and weighed separately with an electronic scale until the mass of each raw material in the container reaches the required amount. Finally, the raw materials are poured into the mixing device to complete the proportioning. This proportioning method can achieve very precise control of the amounts of various raw materials added.

[0004] However, in the proportioning method of the prior art, when producing acrylic emulsion multiple times, when the functions of the required acrylic emulsion are the same but the demand amounts are different, it is still necessary to reweigh various raw materials, which is very time-consuming and laborious. Content of the Utility Model

[0005] The purpose of the utility model is to provide a raw material proportioning device for acrylic emulsion preparation to solve the problems raised in the above background technique.

A first screw hole is provided on the limiting component mounting plate, and a first hand-tightening screw is rotatably connected in the first screw hole. An internal thread is provided in the first screw hole, and an external thread is provided on the first hand-tightening screw.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1 to 6, the utility model provides a technical solution: a raw material proportioning device for acrylic emulsion preparation, including: a container 1, and several groups of the container 1 are provided. A material bearing plate 2 is slidably connected in the container 1. Connecting rods 4 are fixed on both symmetric end faces of the material bearing plate 2. Connecting rod holes 3 are opened on both symmetric end faces of the container 1. The two groups of connecting rods 4 are respectively slidably connected in the two groups of connecting rod holes 3. Limiting mechanisms are provided at one ends of the two groups of connecting rods 4 away from the material bearing plate 2. A positioning plate 9 is fixed at one end of one of the limiting mechanisms away from the material bearing plate 2. A scale mounting rod 10 is fixed at one end of the other limiting mechanism away from the material bearing plate 2. A scale groove 11 is opened on the positioning plate 9. A scale 12 is fixed on the scale mounting rod 10. The scale 12 on one of the containers 1 is movably inserted into the scale groove 11 on the other container 1. A positioning mechanism is provided between the scale groove 11 and the scale 12. The container 1 has a "hui"-shaped cylinder structure, and the material bearing plate 2 has a rectangular plate structure. The material bearing plate 2 cooperates with the inner ring of the container 1. Several groups of scale lines 16 are opened on both symmetric end faces of the container 1. The several groups of scale lines 16 are linearly arrayed in the up and down directions.

[0023] In actual use, first calculate the volume ratio between the various raw materials required, and prepare the same number of containers 1 as the required types of raw materials. Arrange the containers 1 in a row, and insert the scale 12 on the rear container 1 into the groove 11 on the positioning plate 9 of the front container 1. Then, adjust the height of the material support plate 2 in each container 1 according to the required volume of various raw materials. The volume of raw materials in the first group increases sequentially to the last group. When adjusting the height of each group of material support plates 2, first adjust the material support plate 2 in the first group of containers 1. When adjusting the material support plate 2 in the first group of containers 1, first release the limiting mechanism. The limit is set, and then the volume of container 1 is determined according to the scale line 16 on container 1. The volume of container 1 is required to be equal to the volume of the smallest required raw material. After the height of the first set of material support plates 2 is adjusted, the limit of the first set of material support plates 2 is restored. Then the height of the second set of material support plates 2 is adjusted. During adjustment, the limit of the second set of material support plates 2 is released. According to the volume ratio between the volume of the second smallest required raw material and the previous raw material, the scale on the scale 12 is observed and the height of the scale 12 in the groove 11 is adjusted to determine the height of the second set of material support plates 2. After the height is determined, the scale 12 is positioned using a positioning mechanism. Position the material and simultaneously restore the limit of the second set of support plates 2; adjust the height of each set of support plates 2 in this manner. After adjustment, pour each set of raw materials into its corresponding container 1 in sequence. Once each container 1 is full, the mixing is complete. When it is necessary to mix the same acrylic emulsion with different required quantities, simply release the limit of each set of support plates 2, maintain the positioning between each set of grooves 11 and scale 12, then recalculate the volume of raw materials corresponding to the first set of container 1 and adjust the height of the first set of support plates 2. The height of the remaining sets of support plates 2 will then be adjusted synchronously with the first set of support plates 2. After adjustment, restore the height of each set of support plates 2. The limiting position of the material receiving plate 2 allows various raw materials to be poured into their corresponding material receiving plate 2. Once filled, the mixing can be quickly completed. Similarly, based on the types and volumes of raw materials required for different functions of acrylic emulsions, after calculating the volume ratio, multiple sets of mixing devices consisting of multiple sets of containers 1 are set up. When mixing acrylic emulsions of various functions, the corresponding set of mixing devices is taken out. Then, only the volume of the raw material corresponding to the first set of containers 1 needs to be calculated. After that, the limiting position of each set of material receiving plates 2 is released, the height is adjusted, and the limiting position is restored. After pouring various raw materials into the corresponding containers 1 and filling them, the mixing of acrylic emulsions of that function can be quickly completed.

[0024] Example 2: Based on Example 1, in order to realize the operation of the limiting mechanism, the limiting mechanism includes: a limiting component mounting plate 5, the limiting component mounting plate 5 is fixed to the end of the connecting rod 4 away from the material receiving plate 2, the limiting component mounting plate 5 is provided with a first screw hole 6, a first hand-tightening screw 7 is rotatably connected in the first screw hole 6, the first screw hole 6 is provided with an internal thread, the first hand-tightening screw 7 is provided with an external thread, the internal thread of the first screw hole 6 and the external thread of the first hand-tightening screw 7 are engaged, a first limiting rod 8 is fixed on the first hand-tightening screw 7, and the end of the first limiting rod 8 away from the first hand-tightening screw 7 abuts against the surface of the container 1.

[0025] Tightening the first hand-tightening screw 7 causes the first limiting rod 8 to move away from the container 1 through the threaded connection between the first screw hole 6 on the limiting component mounting plate 5 and the first hand-tightening screw 7. This releases the limiting of the connecting rod 4 and thus the limiting of the material support plate 2. Tightening the first hand-tightening screw 7 in the opposite direction causes the first hand-tightening screw 7 to move the first limiting rod 8 closer to the container 1. This presses the first limiting rod 8 against the container 1. After the container 1 generates a large frictional force on the first limiting rod 8, the limiting of the connecting rod 4 is restored, and thus the limiting of the material support plate 2 is restored.

[0026] Example 3: Based on Example 2, in order to realize the operation of the positioning mechanism, the positioning mechanism includes a second screw hole 13, which is opened on the positioning plate 9. A second hand screw 14 is rotatably connected in the second screw hole 13. The second screw hole 13 has an internal thread, and the second hand screw 14 has an external thread. The internal thread of the second screw hole 13 and the external thread of the second hand screw 14 are engaged. A second limiting rod 15 is fixed on the second hand screw 14. The end of the second limiting rod 15 away from the second hand screw 14 abuts against the surface of the scale 12.

[0027] Tighten the second hand-tightening screw 14. Under the threaded connection between the second hand-tightening screw 14 and the second screw hole 13 on the positioning plate 9, the second hand-tightening screw 14 drives the second limiting rod 15 to move away from the scale 12. Then, the height of the scale 12 fixed on the scale mounting rod 10 in the scale groove 11 can be adjusted. The scale 12 has graduations when adjusting, which facilitates the positioning of the scale 12. After adjusting to the required height, turn the second hand-tightening screw 14 in the opposite direction. The second hand-tightening screw 14 drives the second limiting rod 15 to move closer to the scale 12, and finally presses the second limiting rod 15 onto the scale 12, thus completing the positioning.

[0028] Example 4: Based on Example 3, in order to prevent the raw materials in container 1 from leaking to the outside through the connecting rod hole 3, a sealing plate 17 is fixed to the top of the connecting rod 4, and the sealing plate 17 is movably inserted into the connecting rod hole 3.

[0029] A sealing plate 17 is fixed to the top of the connecting rod 4. The sealing plate 17 seals the part of the connecting rod hole 3 located above the connecting rod 4, thereby preventing the raw material in the container 1 from leaking to the outside through the connecting rod hole 3.

[0030] In actual use, first calculate the volume ratio between the various raw materials required, and prepare the same number of containers 1 as the required types and quantities of raw materials. Arrange the containers 1 in a row, and insert the scale 12 on the rear container 1 into the groove 11 on the positioning plate 9 of the front container 1. Then, adjust the height of the material support plate 2 in each group of containers 1 according to the required volume of various raw materials. The volume of raw materials in the first group increases sequentially from the last group. When adjusting the height of each group of material support plate 2, first adjust the material support plate 2 in the first group of containers 1. When adjusting the first group of material support plate 2, first release the limit mechanism, and then determine the height of the container according to the scale line 16 on the container 1. The volume of container 1 must be equal to the volume of the smallest required raw material. After adjusting the height of the first set of receiving plates 2, restore the limit position of the receiving plates 2. Then, adjust the height of the second set of receiving plates 2. During adjustment, release the limit position of the second set of receiving plates 2. Observe the scale on the ruler 12 according to the volume ratio between the second smallest required raw material and the previous raw material, and adjust the height of the ruler 12 in the groove 11 to determine the height of the second set of receiving plates 2. After determination, use the positioning mechanism to position the ruler 12 and restore the limit position of the second set of receiving plates 2. Adjust the height of each set of receiving plates 2 in this way. After adjustment, sequentially move each set of raw materials... Pour the materials into their corresponding containers 1. Once each set of containers 1 is full, the mixing ratio is complete. When it is necessary to mix the same acrylic emulsion with different required quantities for the same function, simply release the limiting positions of each set of receiving plates 2, maintain the positioning between each set of grooves 11 and scales 12, then recalculate the volume of the raw material corresponding to the first set of containers 1 and adjust the height of the first set of receiving plates 2. The heights of the remaining sets of receiving plates 2 will then be adjusted synchronously with the first set of receiving plates 2. After adjustment, restore the limiting positions of each set of receiving plates 2, pour the various raw materials into their corresponding receiving plates 2, and once full, the mixing ratio is quickly completed. Similarly, based on the types and volumes of raw materials required for different functions of acrylic emulsions, calculate the volume ratio and set up multiple sets. The mixing device, consisting of multiple sets of containers 1, allows for the mixing of various functional acrylic emulsions. The corresponding mixing device is then used, and the volume of the raw material corresponding to the first set of containers 1 is calculated. After releasing the limiting position, adjusting the height, and restoring the limiting position of each set of material support plates 2, the various raw materials are poured into the corresponding containers 1 until they are full, thus quickly completing the mixing of the acrylic emulsion for that function. Tightening the first hand-tightening screw 7, through the threaded connection between the first screw hole 6 on the limiting component mounting plate 5 and the first hand-tightening screw 7, causes the first hand-tightening screw 7 to move the first limiting rod 8 away from the container 1, thereby releasing the limiting position of the connecting rod 4 and consequently releasing the limiting position of the material support plate 2.Tighten the first hand-tightening screw 7 in the reverse direction, causing it to move the first limiting rod 8 closer to the container 1. This ultimately presses the first limiting rod 8 against the container 1. The container 1 generates significant friction on the first limiting rod 8, thus restoring the limiting position of the connecting rod 4, and consequently, the limiting position of the material receiving plate 2. Tighten the second hand-tightening screw 14. Through the threaded connection between the second hand-tightening screw 14 and the second screw hole 13 on the positioning plate 9, the second hand-tightening screw 14 moves the second limiting rod 15 away from the scale 12. This allows the scale mounting rod 10 to be adjusted. The height of the fixed scale 12 in the groove 11 is adjusted. The scale 12 has graduations for easy positioning. After adjusting to the desired height, the second hand-tightening screw 14 is turned in the opposite direction. The second hand-tightening screw 14 moves the second limiting rod 15 closer to the scale 12, ultimately pressing the second limiting rod 15 against the scale 12, thus completing the positioning. A sealing plate 17 is fixed to the top of the connecting rod 4. The sealing plate 17 seals the portion of the connecting rod hole 3 located above the connecting rod 4, thereby preventing the raw material in the container 1 from leaking to the outside through the connecting rod hole 3.
