Description

TECHNICAL FIELD

[0001] The utility model relates to a glue spraying production equipment technical field, concretely relates to a kind of low viscosity fast sticking environmental protection glue preparation system. BACKGROUND

[0002] Low viscosity fast sticking environmental protection glue usually uses environmental protection mixed organic solvent as medium, combines modified synthetic rubber with excellent dissolving performance, tackifying resin and environmental protection auxiliary agent, this glue is low VOC, high solid content, does not contain heavy metal, low taste, with outstanding initial tack, bonding strength, holding tack, heat resistance and ageing resistance performance, short drying time, applicable to wood, cloth, leather, plastic, metal and other materials.

[0003] In the preparation process of the above glue, there are still the following problems: first, most of the raw materials are stirred using a mixer, but the stirring device mostly has the problem of uneven stirring, and part of the glue will always adhere to the inner wall of the stirring device due to the viscosity of the glue, thereby affecting the quality of the glue;Second, the glue often produces bubbles during production, and the bubble content is an important indicator of glue quality, which needs to be deaerated, the current deaeration methods mainly include chemical method and physical method, the chemical method is to add chemical defoaming agent in the glue, but the defoaming agent will be left in the glue and make the glue deteriorate, the physical method mostly uses vacuum method, but when the volume of glue barrel is large, the bubbles at the bottom of the barrel are difficult to be pumped up in a short time, and if the volume of glue barrel is reduced, it cannot meet the needs of normal production. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a kind of low viscosity fast sticking environmental protection glue preparation system with good stirring effect, high deaeration efficiency and good product quality.

[0005] The utility model discloses a stirring device for rubber mixing, which comprises a mixing tank and a reaction tank, and a plurality of raw material tanks.

[0006] Further, each raw material tank is provided with a weighing tank below.

[0007] Further, the end of the inner rod is provided with a scraper driving mechanism which can drive the rotation of the annular scraper.

[0008] Further, the end of the inner rod is provided with a scraper driving mechanism which can drive the rotation of the annular scraper.

[0009] Further, the top of the reaction tank is provided with an exhaust pipe, and the exhaust pipe is provided with a gas purifier.

[0010] Further, the inner wall of the bubble-removing cylinder is provided with a plurality of glue guide plates.

[0011] Further, the inner wall of the bubble-removing cylinder is provided with a plurality of glue guide plates.

[0012] In operation, the various raw materials required for spraying adhesive are separately loaded into their respective raw material tanks and introduced into the mixing tank as needed. A stirrer is used to agitate the raw materials, achieving preliminary mixing. The upper drive mechanism is then activated, causing the mixing drum to rotate. The preliminarily mixed mixture is then introduced into the mixing drum of the reaction tank. An annular scraper agitates the raw materials, promoting mixing, and simultaneously scrapes the inner surface of the mixing drum, removing any adhering raw materials and ensuring thorough mixing with the other materials. Once the mixture is complete and the spray adhesive is formed, the mixing drum... The feed pipe on the upper part of the container faces downwards, while the feed pipe on the reaction vessel faces upwards. At this point, the two feed pipes are directly opposite each other. Open the gate valve, and the adhesive sprayed in the mixing drum falls into the defoaming cylinder through the feed pipe. After closing the gate valve, start the lower drive mechanism to drive the defoaming cylinder to rotate. At the same time, start the vacuum pump to evacuate the inside of the defoaming cylinder, causing the air bubbles in the adhesive to be expelled. The adhesive sprayed in the defoaming cylinder is constantly tumbling, which can quickly and efficiently remove all the air bubbles in the adhesive. After the defoaming process is completed, turn the feed pipe on the defoaming cylinder downwards and open the gate valve to discharge the defoamed adhesive for subsequent filling and other processes, thus completing the preparation of the adhesive spray. In this invention, various raw materials are initially mixed in a mixing tank using a stirrer, and then introduced into a mixing drum. The mixing drum is constantly rotating and equipped with an annular scraper, which both scrapes the inner wall of the mixing drum and stirs the various raw materials, improving the uniformity of the mixing and preventing some of the adhesive from adhering to the inner wall of the mixing drum, thus ensuring the quality of the adhesive. Secondly, this invention uses a physical method for defoaming, employing a vacuum method to remove air bubbles from the adhesive. During the defoaming process, the adhesive is constantly agitated, ensuring that all parts of the adhesive are at the top, thereby quickly removing air bubbles. This method avoids the use of chemical defoaming methods, preventing the addition of chemical defoamers that could cause deterioration. Furthermore, the continuous rotation of the defoaming drum eliminates the problem of air bubbles at the bottom being difficult to remove quickly in traditional vacuum defoaming processes, shortening the defoaming time and significantly improving defoaming efficiency and effect. This results in high-quality adhesive while meeting the needs of normal production. In summary, this invention has the advantages of good stirring effect, high defoaming efficiency, and good product quality. Attached Figure Description
