DETAILED DESCRIPTION

[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0023] according to Figure 1 - Figure 4 This embodiment provides an efficient and energy-saving acrylic pressure-sensitive adhesive packaging device, including a polymerization kettle 1 and a three-way valve 2. The polymerization kettle 1 is used for the polymerization processing of acrylic pressure-sensitive adhesive, such as Figure 1 and Figure 3 As shown, a first filter 3, a material pump 4 and a second filter 5 are provided between the polymerization kettle 1 and the three-way valve 2, and the corresponding polymerization kettle 1, the first filter 3, the material pump 4, the second filter 5 and the three-way valve 2 are connected in sequence, that is, during the production process, the acrylic pressure-sensitive adhesive is first formed in the polymerization kettle 1, and then passes through the first filter 3, the material pump 4 and the second filter 5 in sequence, and finally passes through the three-way valve 2 to the packaging machine for packaging.

[0024] Specifically, a feed pipe 6 is installed at the lower end of the polymerization kettle 1, and a hollow sampling port 22 is installed at the lower end of the polymerization kettle 1. A fourth valve is installed on the hollow sampling port 22 to facilitate sampling during the processing of the acrylic pressure-sensitive adhesive. One side of the feed pipe 6 is connected to the first filter 3 through the first relay pipe 7, so the material in the feed pipe 6 is first filtered through the first filter 3. A nitrogen pipeline 8 is provided on one side of the first relay pipe 7, and the nitrogen pipeline 8 is connected to the feed pipe 6. Specifically, Figure 2As shown, the nitrogen pipeline 8 includes a nitrogen pipeline 18, on which a shut-off valve 19, a gas control valve 20 and a third valve 21 are sequentially installed. When working, the nitrogen pipeline 18 is connected to an external nitrogen supply pipeline to ensure that nitrogen can directly enter during operation.

[0025] The corresponding three-way valve 2 has a port, and there are three groups of ports, one group of ports is connected to the feed port of the polymerization kettle 1 through the circulation pipeline 9, and the other two groups of ports are respectively connected to the second filter 5 and the packaging machine through pipelines. Therefore, the three-way valve 2 can be switched according to needs, which is convenient and quick to use.

[0026] The first filter 3 and the material pump 4 are connected through the second relay pipe 10, and a recovery funnel 11 is provided on one side of the second relay pipe 10. The input end of the recovery funnel 11 is connected to the second relay pipe 10 through the first valve 12. Through the recovery funnel 11, when the material needs to be recovered, the corresponding valve is opened and the other valves are closed, thereby directly recovering the material through the recovery funnel. Therefore, the device opens and closes the valve to facilitate switching between different working states when the device is working, which is more convenient as a whole and has the effects of fast switching and efficient production, thereby achieving the effect of high efficiency and energy saving to meet the production needs of customers.

[0027] A circulation pipeline 13 is provided between the material pump 4 and the second filter 5. The material pump 4 is connected to the circulation pipeline 13 through a third relay pipe 14, and the circulation pipeline 13 is connected to the second filter 5 through a second valve 15. A return valve 16 is installed on the corresponding circulation pipeline 13, and the return valve 16 is connected to the polymerization kettle 1 through a return pipeline 17. Pressure gauges 23 are installed on both the circulation pipeline 13 and the second filter 5.

[0028] In this embodiment, the first relay pipe 7 , the second relay pipe 10 and the second relay pipe 14 are all hoses.

[0029] like Figure 4 As shown, it is an acrylic pressure-sensitive adhesive packaging device adopted in the prior art, and its nitrogen pipeline 8 is usually connected to the top of the polymerization kettle 1. Therefore, during operation, if the nitrogen flow rate is too small, or the blowing direction is wrong, then in some areas, the nitrogen may not be able to reach, forming a dead corner, that is, there are problems of dead corners and low efficiency. Then in this device, the position of the nitrogen pipeline 8 is changed to make it close to the bottom of the polymerization kettle, that is, it is blown out from the discharge pipe 6, changing the traditional blowing direction, thereby improving efficiency.

[0030] In the prior art, only the materials going to the packaging machine will be filtered once, but in the processing of acrylic pressure-sensitive adhesive, the tail materials and the head materials will be recycled and reused. However, they cannot be filtered during the recycling process, which will cause foreign particles to be brought into the new product, which will not only increase the pressure of the filter, but also increase the time required for filtration. Therefore, in this device, the structure is changed, so that the head materials and the tail materials are returned to the kettle through the filter, and the particles are not replaced by new products, which can ensure uniform packaging quality and reduce packaging deviation.

[0031] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
