Description

Technical Field

[0001] This application relates to the technical field of adhesive processing equipment, and in particular to an adhesive cooling device. Background Technology

[0002] Decorative paper has a wide range of applications in modern decoration, and the development of its production technology is crucial for improving decorative effects and product quality. As people's requirements for the performance of decorative paper continue to increase, such as toughness, wear resistance, and tear resistance, the production process of decorative paper is also constantly being improved. Impregnation with adhesive is a key step in improving the performance of decorative paper. The application of adhesive in the production of decorative paper enables it to achieve better physical properties, meeting the needs of different applications and driving the development of the decorative paper industry.

[0003] In decorative paper production, the preparation and use of adhesive are crucial steps. Adhesive typically forms long-chain or network polymers by linking monomer molecules together, a process that releases a significant amount of heat, causing the adhesive temperature within the preparation tank to rise. Decorative paper production requires adhesive at specific temperatures. To ensure the adhesive reaches the appropriate operating temperature, the traditional method is to allow the prepared adhesive to cool naturally within the preparation tank. Since the preparation tank is a container with an inlet at the top, this is a common practice in the industry. Operators typically wait for the adhesive to cool naturally to the suitable temperature before pumping it to the decorative paper production line for use.

[0004] However, the existing technology has significant drawbacks. Due to the large volume of the preparation tank, the adhesive takes a long time to cool while standing still inside. This results in the adhesive not being usable in a timely manner, affecting the production efficiency of decorative paper and hindering efficient production, which requires improvement. Utility Model Content

[0005] The purpose of this application is to provide an adhesive cooling device to improve the efficiency of adhesive cooling.

[0006] The adhesive cooling device provided in this application adopts the following technical solution: it includes a preparation tank and a cooling box, the cooling box is filled with cooling water, the preparation tank is connected to a material extraction pipe, the material extraction pipe is connected to a material extraction pump, the end of the material extraction pipe away from the preparation tank is connected to the cooling box, a connecting pipe is connected inside the cooling box, the material extraction pipe is connected to the connecting pipe, the cooling box is connected to a return pipe, the connecting pipe is connected to the return pipe, the end of the return pipe away from the cooling box is connected to the preparation tank, and a temperature detector is connected inside the preparation tank.

[0007] By adopting the above technical solution, when the temperature detector detects that the temperature of the adhesive in the preparation tank is too high, the pump is turned on. The adhesive in the preparation tank is then pumped into the cooling tank through the pump and the pump pipe. After being cooled by heat exchange with cooling water through the connecting pipe in the cooling tank, it returns to the preparation tank through the return pipe, realizing the circulation and cooling of the adhesive and effectively shortening the cooling time. When the temperature detector detects that the temperature of the adhesive in the preparation tank has reached the appropriate value, the pump is turned off.

[0008] Optionally, the connecting pipe includes two converging pipes and several branch pipes, with the branch pipes located between the two converging pipes and both ends of the branch pipes connected to the two converging pipes respectively. The extraction pipe and the return pipe are respectively connected to the two converging pipes.

[0009] By adopting the above technical solution, the extraction pipe transports the glue in the preparation tank to the connecting pipe. The distribution pipe of the connecting pipe can disperse the glue flow, increase the contact area between the glue and the cooling water in the cooling tank, and improve the cooling efficiency of the glue.

[0010] Optionally, the diverter is arranged in a spiral shape.

[0011] By adopting the above technical solution and setting the distribution pipe in a spiral shape, the flow path and residence time of the adhesive in the cooling box can be increased, so that the adhesive and cooling water can be fully contacted, thereby improving the cooling efficiency of the adhesive.

[0012] Optionally, a stirring column is rotatably connected inside the cooling box. A plurality of first stirring blades are provided on the outer circumferential surface of the stirring column. The stirring column is located on one side of the distribution pipe. The rotation direction of the first stirring blades is towards the distribution pipe. The cooling box is connected to a first driving member, which is used to drive the stirring column to rotate.

[0013] By adopting the above technical solution, when the glue exchanges heat with the cooling water through the connecting pipe inside the cooling box, the first driving component drives the stirring column to rotate, and all the first stirring blades rotate around the axis of the stirring column. During the rotation of the first stirring blades, the cooling water in the cooling box can flow, preventing the temperature of the cooling water at the distribution pipe from being too high, enhancing the heat exchange between the cooling water and the glue in the distribution pipe, and improving the cooling efficiency.

[0014] Optionally, there are two stirring columns, and the diversion pipe is located between the two stirring columns, with the two stirring columns rotating in opposite directions.

[0015] By adopting the above technical solution, the two stirring columns rotate in opposite directions, which allows the cooling water to flow more fully, enhances the heat exchange effect between the cooling water and the glue in the distribution pipe, and accelerates the cooling speed of the glue.

[0016] Optionally, the first stirring blades on the two stirring columns are arranged in an alternating pattern.

[0017] By adopting the above technical solution, the two stirring columns with opposite rotation directions and staggered first stirring blades can make the cooling water flow range larger, and the cooling water can come into more full contact with the distribution pipe, thereby improving the cooling efficiency of the glue and reducing the cooling time of the glue.

[0018] Optionally, a baffle is connected inside the preparation barrel, and the outlet of the return pipe faces the baffle.

[0019] By adopting the above technical solution, the glue is sprayed out of the discharge port of the return pipe and impacted by the baffle, which can disperse the glue in the preparation tank, prevent the glue from concentrating in one place, and make the glue more evenly distributed in the preparation tank, thereby accelerating the cooling speed of the glue.

[0020] Optionally, a stirring rod is rotatably connected inside the preparation tank, and the stirring rod is connected to a plurality of second stirring blades. The second stirring blades are inclined, and the preparation tank is connected to a second driving member, which is used to drive the stirring rod to rotate.

[0021] By adopting the above technical solution, the second driving component drives the stirring rod to rotate, and the second stirring blade rotates around the axis of the rotating rod. The second stirring blade makes the glue in the preparation tank fully mixed, improves the temperature uniformity of the glue, and further accelerates the cooling speed of the glue.

[0022] Optionally, the extraction pipe includes a main pipe and several branch pipes, all of which are connected to the main pipe. The extraction pump is connected to the main pipe, and the end of each branch pipe away from the main pipe is connected to the preparation tank.

[0023] By adopting the above technical solution, multiple branch pipes can draw glue from multiple positions in the preparation tank, making the glue extraction more uniform and improving the efficiency of glue cooling.

[0024] Optionally, the temperature detector is located between the outlet of the return pipe and the inlet of the branch pipe.

[0025] By adopting the above technical solution, the temperature detector is set between the outlet of the return pipe and the inlet of the branch pipe, which can more accurately detect the temperature of the glue after reflow and the glue in the preparation tank. This provides a more accurate basis for judging whether the glue has reached the appropriate temperature to enter the production line.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. When the temperature detector detects that the temperature of the glue in the preparation tank is too high, the pump is turned on. The glue in the preparation tank is pumped into the cooling box through the pump and the pump pipe. After being cooled by heat exchange with cooling water through the connecting pipe in the cooling box, it is returned to the preparation tank through the return pipe, realizing the circulation and cooling of the glue and effectively shortening the glue cooling time.

[0027] 2. The extraction pipe transports the glue in the preparation tank to the connecting pipe. The distribution pipe of the connecting pipe can disperse the glue flow, increase the contact area between the glue and the cooling water in the cooling tank, and improve the cooling efficiency of the glue.

Taking this embodiment as an example, there are four branch pipes 52, and each branch pipe 52 is arranged in a spiral shape.

[0040] Combination Figure 4 and Figure 5As shown, two stirring columns 21 are rotatably connected inside the cooling tank 2. All the distribution pipes 52 are located between the two stirring columns 21. Several first stirring blades 22 are arranged on the outer circumference of each stirring column 21, spaced apart along the length of the column.

[0042] The implementation principle of the glue cooling device in this application embodiment is as follows: When the temperature detector detects that the temperature of the glue in the cooling tank 2 is too high, the pump 4 is turned on. The pump 4, the main pipe 31 and several branch pipes 32 are used to pump the glue in the preparation tank 1 into the connecting pipe 5. After the glue is cooled by heat exchange with the cooling water in the connecting pipe 5 in the cooling tank 2, it returns to the preparation tank 1 through the return pipe 12, realizing the glue circulation cooling and effectively shortening the cooling time of the glue.
