Description

Technical Field

[0001] The utility model belongs to the technical field of styrene-acrylic emulsion, and particularly relates to a raw material premixing device for the production of styrene-acrylic emulsion. Background Technique

[0002] Styrene-acrylic emulsion is obtained by emulsion copolymerization of styrene and acrylate monomers. Styrene-acrylic emulsion is a system that has been studied more in emulsion polymerization and is also one of the top ten non-crosslinked emulsions with important industrial application value in the world today. It has good adhesion, transparent film, and good water, oil, heat, and aging resistance. It is mainly used as architectural coatings, metal surface latex coatings, floor coatings, paper adhesives, adhesives, etc. It can also be used as a paper adhesive in combination with adhesives such as starch, polyvinyl alcohol, and sodium carboxymethyl cellulose. During the production and processing of styrene-acrylic emulsion, raw materials need to be pretreated, and a large amount of raw materials are stirred evenly by a premixing device and then emulsified by an emulsifying device. However, it still has the following disadvantages in actual use:

[0003] 1. The utility model with the publication number CN218593504U discloses a raw material premixing device for polyurethane high-pressure foaming equipment. A mixing tank is installed inside the upper end of the support. Feeding hoppers are installed on both sides of the upper end of the mixing tank. A bracket is installed in the middle of the upper end of the mixing tank. A first motor is installed inside the bracket. A rotating frame is arranged on the output shaft of the first motor. A protective shell is arranged on one side of the upper end of the rotating frame. When processing raw materials, they need to be mixed evenly in the mixing tank and then transported to the next processing device for treatment, resulting in low production efficiency. Moreover, both the mixing tank and the processing device require a large amount of space, reducing the space utilization rate in the production workshop.

[0004] 2. When processing a large amount of styrene-acrylic emulsion, raw materials often need to be processed in batches. To avoid the residual influence of the previous batch of raw materials on the ratio accuracy of the next batch of raw materials, the mixing tank often needs to be cleaned, increasing the labor intensity of workers and production expenses.

The bottom of the inner part of the mixing pipe 3 is clamped and fixed with a vibration motor 306;

[0029] When installing the emulsifying treatment device, the support plate 1 is fixed to the inner top of the emulsifying treatment device by bolts. When raw materials need to be pretreated, the accurately proportioned raw materials are poured into the emulsifying treatment device. The winding motor 204 is controlled to drive the winding roller 203 to rotate to unwind the connecting rope 201, so that the mixing pipe 3 is inserted into the raw materials. The vibration motor 306 drives the mixing pipe 3 to vibrate to vibrate and mix the raw materials. At the same time, the feeding motor 304 drives the spiral feeding component 301 to rotate, so that the raw materials enter the mixing pipe 3 for further mixing. When mixing, the rotating motor 101 drives the rotating frame 104 to rotate, further driving the mixing pipe 3 to horizontally move in the emulsifying treatment device to fully mix the raw materials at various positions in the emulsifying treatment device.

[0030] Among them, as Figures 1-4As shown in the figure, a mounting plate 102 is fixedly welded to the top of the outer peripheral surface of the support plate 1. A rotating motor 101 is snap-fitted through the top of the support plate 1. A driving roller 103 is snap-fitted to the bottom of the rotating motor 101. The driving roller 103 meshes with the inner wall of the rotating frame 104.

[0031] A support frame 202 is fixedly welded inside the control frame 2. A winding roller 203 is rotatably snap-fitted inside the support frame 202. A winding motor 204 is snap-fitted through one side of the support frame 202. One end of the winding roller 203 is snap-fitted to one side of the winding motor 204.

[0032] The support plate 1 is installed and fixed to the inner top of the emulsification treatment device by bolts passing through the mounting plate 102. After various raw materials are poured into the inside of the emulsification treatment device, the winding motor 204 drives the winding roller 203 to rotate, further unwinding the connecting rope 201 to adjust the height of the mixing pipe 3 inside the emulsification treatment device. The rotating motor 101 drives the driving roller 103 to rotate, further driving the rotating frame 104 to rotate, so that the mixing pipe 3 moves horizontally inside the emulsification treatment device, adjusting the position of the mixing pipe 3 inside the emulsification treatment device to uniformly mix materials at multiple positions.

At the same time, the vibration motor 306 drives the vibration of the mixing pipe 3 to vibrate and mix the raw materials inside the mixing pipe 3 and the raw materials inside the emulsification treatment device, improving the mixing efficiency.

[0035] The specific working principle of the utility model is as follows: The support plate 1 is installed and fixed at the inner top of the emulsifying treatment device by bolts passing through the mounting plate 102. When pretreatment of raw materials is required, the accurately proportioned raw materials are poured into the emulsifying treatment device. The winding motor 204 drives the winding roller 203 to rotate, further unreeling the connecting rope 201, adjusting the height of the mixing pipe 3 in the emulsifying treatment device. The driving roller 103 is driven to rotate by the rotating motor 101, further driving the rotating frame 104 to rotate, so that the mixing pipe 3 moves horizontally in the emulsifying treatment device, adjusting the position of the mixing pipe 3 in the emulsifying treatment device. The feeding motor 304 drives the rotating rod 302 and the spiral feeding assembly 301 to rotate, so that the raw materials in the emulsifying treatment device are input into the mixing pipe 3, and the raw materials entering the mixing pipe 3 are mixed evenly through the porous plate 305. At the same time, the vibration motor 306 drives the vibration of the mixing pipe 3 to vibrate and mix the raw materials in the mixing pipe 3 and the raw materials in the emulsifying treatment device. After the raw materials are mixed evenly, the winding motor 204 is controlled to rotate the winding roller 203 in the reverse direction, winding the connecting rope 201, and scraping off the raw materials adhering to the surface of the connecting rope 201 through the scraping assembly 205. When the raw materials are emulsified by the emulsifying treatment device and the emulsifying treatment device is cleaned, the connecting rope 201 is controlled to unreel the mixing pipe 3, so that the mixing pipe 3 is inserted into the cleaning liquid and cleaned together with the emulsifying treatment device.
