Description

Technical Field

[0001] The utility model relates to a stirring device, in particular to a vacuum stirring device for epoxy resin glue. Background Art

[0002] In industrial production, epoxy resin glue is a commonly used adhesive, which is made by mixing epoxy resin, curing agent and auxiliary agent in a certain proportion. It has excellent properties such as high bonding strength, chemical corrosion resistance and anti-aging, making it widely used in various fields. However, epoxy resin glue is also easy to be oxidized. If epoxy resin glue containing a large number of bubbles is directly stored, or if epoxy resin glue is stored in an environment with high oxygen content, high temperature and high humidity, epoxy resin glue will accelerate oxidation and lose its bonding ability in a short time. The oxidation of epoxy resin glue is mainly due to the oxidation reaction between the double bonds and epoxy groups in the resin molecules and oxygen, producing free radicals and oxides such as hydrogen peroxide. These oxides further lead to the breakage of resin molecules, causing the glue to turn yellow and become brittle, and lose its bonding ability.

[0003] When using a traditional vacuum stirring device to make epoxy resin glue, many bubbles will be generated during the stirring process, which will be detrimental to the storage of the epoxy resin glue. In addition, when the vacuum pump is extracting the gas in the stirring device, it is inevitable that some impurities in the device will be extracted. Since the traditional vacuum stirring device lacks corresponding filtering equipment, the impurities extracted by the vacuum pump will be adsorbed in the vacuum pump. Over time, the impurities adsorbed in the vacuum pump may block the vacuum pump port, thereby causing the vacuum pump of the device to malfunction, which not only affects the working efficiency of the device, but may also affect the quality of the epoxy resin glue produced.

[0004] Therefore, it is necessary to design a vacuum stirring device for epoxy resin glue. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment: A vacuum stirring device for epoxy resin adhesive, such as Figure 1-5As shown, it includes a mixing table 1, a support frame 101, a support member 2, a mixing barrel 6, a servo motor 7, a stirring rod 8, a barrel cover 10, a support block 14, a vacuum pump 15, a filter 16, a pull-out filter screen 17, a vacuum pressure gauge 20, an air outlet valve 21, a threaded cover 22, a control panel 23, a feeding mechanism and a discharging mechanism. A support frame 101 is welded to the right side of the top of the mixing table 1, four support members 2 are welded to the bottom of the mixing table 1, a mixing barrel 6 is installed in the middle of the mixing table 1, a servo motor 7 is connected to the middle of the bottom of the support frame 101 by bolts, a stirring rod 8 is connected to the output shaft at the bottom of the servo motor 7, a barrel cover 10 is provided on the top of the mixing barrel 6, a support block 14 is connected to the upper right side of the mixing table 1 by bolts, a filter 16 is installed on the right side of the mixing barrel 6, a pull-out filter screen 17 is slidably connected to the filter 16, and a pull-out filter screen 17 is slidably connected to the inside of the filter 16. A vacuum pump 15 is installed on the right side of the filter 16, and the right side air outlet of the filter 16 is connected to the left side air inlet of the vacuum pump 15, and the vacuum pump 15 and the filter 16 are both arranged on the top of the support block 14. An air outlet valve 21 is fixedly connected to the middle of the top of the barrel cover 10 by bolts, and a threaded cover 22 is threadedly connected to the top of the air outlet valve 21. A plurality of small holes are opened on the top of the air outlet valve 21, and an air outlet hole is opened on the top of the threaded cover 22. When the small holes on the top of the air outlet valve 21 are aligned with the air outlet holes on the top of the threaded cover 22, gas can enter and exit the device at will. A vacuum pressure gauge 20 is fixedly connected to the middle of the top of the barrel cover 10 by bolts, a control panel 23 is connected to the left front side of the mixing table 1 by bolts, a feeding mechanism is provided on the upper left side of the mixing barrel 6, and the feeding mechanism is fixedly connected to the top left side of the mixing table 1, and a discharging mechanism is provided on the lower front side of the mixing barrel 6.

[0023] like Figure 1-Figure 3 As shown, the feeding mechanism includes a feeding frame 3, a sealing cover 4 and bolts 5. The feeding frame 3 is welded to the upper left side of the mixing barrel 6. The sealing cover 4 is provided on the top of the feeding frame 3. The top of the feeding frame 3 is sealed and connected to the sealing cover 4 by bolts 5.

[0024] like Figure 2 As shown, the discharge mechanism includes a discharge pipe 11, an extrusion pump 12 and a control valve 13. The discharge pipe 11 is welded to the lower front part of the mixing barrel 6, the extrusion pump 12 is installed at the front of the discharge pipe 11, and the control valve 13 is rotatably connected to the middle top of the discharge pipe 11.

[0025] When the staff needs to use this device to stir and make epoxy resin glue, first place this device on the ground, then put the loading container at the bottom of the extrusion pump 12, then turn the bolt 5 on the top of the sealing cover 4 counterclockwise, loosen the bolt 5, open the sealing cover 4, and then pour raw materials such as epoxy resin, curing agent and additives into the feeding frame 3, and the raw materials will enter the mixing barrel 6 through the feeding frame 3. After the raw materials fall into the mixing barrel 6, put the sealing cover 4 back on the top of the feeding frame 3, and then tighten the bolt 5 on the top of the sealing cover 4 clockwise, make sure that the threaded cover 22 is also tightened, and the air outlet at the top of the threaded cover 22 is not aligned with the small hole at the top of the air outlet valve 21, so that the mixing barrel 6 remains sealed.

[0026] When the mixing barrel 6 is in a sealed state, the staff can start the vacuum pump 15 by operating the control panel 23, so that the vacuum pump 15 starts to extract the air inside the mixing barrel 6. Before entering the vacuum pump 15, the gas in the mixing barrel 6 will pass through the filter 16 on the left side of the vacuum pump 15. Under the filtering action of the filter 16, some impurities extracted by the vacuum pump 15 can be filtered onto the pull filter 17. The staff can observe the numerical display on the vacuum pressure gauge 20 to determine the pressure and vacuum degree in the device.

[0027] like Figure 2 As shown, a temperature changing mechanism is also included, which includes a temperature changing tube 18 and a temperature controller 19. The upper front part of the mixing table 1 is connected to the temperature controller 19 by bolts, the output end of the temperature controller 19 is connected to the temperature changing tube 18, and the temperature changing tube 18 is spirally wrapped around the outside of the mixing barrel 6.

[0028] like Figure 3 As shown, a scraper 9 is also included. Four scrapers 9 are welded circumferentially on the upper part of the stirring rod 8. The scraper 9 contacts the inner wall of the stirring barrel 6, and the scraper 9 is made of soft silicone.

[0029] When the vacuum pump 15 has finished extracting the gas in the device, the staff can turn off the vacuum pump 15 by operating the control panel 23, and then turn on the servo motor 7 and the temperature controller 19, so that the output shaft of the servo motor 7 starts to rotate, and the servo motor 7 will drive the stirring rod 8 and the scraper 9 to rotate together, so that the raw materials in the mixing barrel 6 are quickly and fully stirred by the stirring rod 8, and the scraper 9 will scrape off the raw materials adhering to the inner wall of the mixing barrel 6. At the same time, after the temperature controller 19 is turned on, the temperature variable tube 18 starts to create a suitable temperature environment for the raw materials in the mixing barrel 6, which can effectively slow down the drying rate of the raw materials and prevent the raw materials from drying out during the stirring process.

[0030] When the raw materials are fully stirred, the staff needs to turn off the servo motor 7 and the temperature controller 19 through the control panel 23 and set the amount of liquid that the extrusion pump 12 extrudes at one time, and then rotate the threaded cover 22 counterclockwise to align the air outlet hole on the top of the threaded cover 22 with the small hole on the top of the air outlet valve 21, so that the outside air can enter the device. After there is no pressure difference between the inside and outside of the device, the control valve 13 is then rotated counterclockwise to open the discharge pipe 11. The epoxy resin glue prepared in the mixing barrel 6 can enter the extrusion pump 12 through the discharge pipe 11, and the extrusion pump 12 will squeeze a certain amount of epoxy resin glue into the loading container.

[0031] When the epoxy resin glue is collected and the device needs to be cleaned, the staff needs to rotate the bolt 5 on the top of the sealing cover 4 counterclockwise, loosen the bolt 5, open the sealing cover 4, and then pour the special cleaning liquid into the discharge frame 3. When the special cleaning liquid enters the mixing barrel 6, the staff can turn on the servo motor 7 and switch it to the cleaning mode through the operation control panel 23. Driven by the servo motor 7, the stirring rod 8 and the scraper 9 start to rotate, so that the special cleaning liquid can fully clean the device. After the device is cleaned, the staff can rotate the control valve 13 counterclockwise to open the discharge pipe 11. The waste liquid after cleaning the device can be squeezed out through the extrusion pump 12, and the staff can dispose of the waste liquid.

[0032] When the pull-out filter screen 17 in the filter 16 needs to be cleaned, the staff can pull the pull-out filter screen 17 forward to remove it, and then put the pull-out filter screen 17 into a special cleaning liquid for cleaning. After the pull-out filter screen 17 is cleaned, the pull-out filter screen 17 can be put back into the filter 16.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
