[0024] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1:

[0026] The present application provides a wood adhesive mixing mixer, comprising a mixing box 1; a feeding pipe 7 is provided at the bottom of the mixing box 1, and a defoaming mechanism 6 is provided at the top of the feeding pipe 7 at the bottom of the mixing box 1;

[0027] The defoaming mechanism 6 includes a placement tank 601, a vibration motor 602, a mounting block 603, an electromagnet 604 and a filter plate 605. The placement tank 601 is opened at the bottom of the mixing box 1. The vibration motor 602 is fixedly installed inside the placement tank 601. The output end of the vibration motor 602 is fixedly installed with the mounting block 603. The inner wall of the mounting block 603 is embedded with an electromagnet 604. The mounting block 603 is fixedly installed with the filter plate 605 through the electromagnet 604.

[0028] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, after the mixing and stirring of the wood adhesive is completed, bubbles will be generated in the wood adhesive raw material during the stirring process. When the personnel need to discharge the wood adhesive inside the mixing box 1 through the discharge pipe 7, at this time, the vibration motor 602 can be turned on by the external controller, and the filter plate 605 can be driven to vibrate through the output end of the vibration motor 602 to filter the wood adhesive discharged from the mixing box 1 through the discharge pipe 7. This can reduce the bubbles inside the wood adhesive to a certain extent, avoid excessive bubbles affecting the quality of the wood adhesive, and thus improve the service life of the wood adhesive. When the filter plate 605 is blocked after long-term use, the electromagnet 1 604 can be de-energized by the external controller, and the electromagnet 1 604 will be separated from the filter plate 605, making it easier for personnel to disassemble and replace the filter plate 605, thereby further improving the convenience of personnel in disassembling and replacing the filter plate 605, thereby further ensuring the normal use of the device.

[0029] Further, the mixing box 1 is symmetrically provided with a feeding mechanism 2, a stirring mechanism 3 is installed in the inner cavity of the mixing box 1, a heating mechanism 5 is installed in the inner cavity of the mixing box 1, a temperature sensor 9 is embedded in the inner cavity of the mixing box 1, an air pipe 401 is installed on the top of the mixing box 1, and the mixing box 1 is fixedly provided with a vacuum pump 4 through the air pipe 401. The feeding mechanism 2 includes a feeding pipe 201, a quantitative meter 202 and a solenoid valve 203. The feeding pipe 201 is provided at the top of the mixing box 1, the quantitative meter 202 is installed on the surface of the feeding pipe 201, and the solenoid valve 203 is installed at the bottom of the quantitative meter 202. The heating mechanism 5 includes a placement cavity 501, a heating rod 502 and a heat conducting plate 503. The placement cavity 501 is opened on the inner wall of the mixing box 1, and the heating rods 502 are installed at equal intervals inside the placement cavity 501, and a heat conducting plate 503 is provided on the inner side of the heating rod 502.

[0030] Specifically, such as Figure 1 、 Figure 2 As shown, when a person adds the wood adhesive raw material into the inner cavity of the mixing box 1 through the feeding pipe 201, the quantitative meter 202 and the electromagnetic valve 203 can be opened by an external controller, and the flow rate of the wood adhesive inside the feeding pipe 201 can be detected by the quantitative meter 202. When the quantitative meter 202 detects that the flow rate inside the feeding pipe 201 reaches a preset value, the electromagnetic valve 203 can be closed by the external controller, thereby preventing excess wood adhesive from continuing to enter the mixing box 1. By setting up the two sets of feeding mechanisms 2 inside the mixing box 1, the wood adhesive raw material can be quickly and accurately proportioned, thereby further ensuring the quality of the wood adhesive. During the mixing process of the mixing mechanism 3, the interior of the mixing box 1 can be vacuumed by the vacuum pump 4, thereby reducing the generation of bubbles inside the wood adhesive during the mixing process. At the same time, the temperature inside the mixing box 1 can be detected by the temperature sensor 9. When the temperature inside the mixing box 1 is lower than the preset value, the heating rod 502 can be energized by the external controller, and the heat generated by the heating rod 502 when it is energized is introduced into the interior of the mixing box 1 through the heat conducting plate 503, so that the wood adhesive inside the mixing box 1 is fully and evenly heated, thereby avoiding the quality of the wood adhesive being affected by temperature, and thus ensuring the quality of the wood adhesive to a certain extent.

[0031] Furthermore, the stirring mechanism 3 includes a drive motor 301 and a stirring rod 302. The drive motor 301 is fixedly mounted on the top of the stirring box 1. The stirring rod 302 is arranged in the inner cavity of the stirring box 1 and is fixedly connected to the output end of the drive motor 301. A cleaning mechanism 8 is fixedly mounted on the bottom of the stirring rod 302. The cleaning mechanism 8 includes a fixed sleeve 801, a connecting rod 802, a cleaning plate 803 and a second electromagnet 804. The fixed sleeve 801 is mounted on the bottom of the stirring rod 302. The second electromagnet 804 is embedded in the inner wall of the fixed sleeve 801. The connecting rod 802 is symmetrically arranged on the outer side of the fixed sleeve 801. The cleaning plate 803 is fixedly mounted on one end of the connecting rod 802.

[0032] Specifically, such as Figure 1 、 Figure 2As shown, when the device is mixing the wood adhesive, the wood adhesive raw material is added to the inner cavity of the mixing box 1 through the feeding mechanism 2, the driving motor 301 is turned on by the external controller, and the stirring rod 302 is driven to rotate by the output end of the driving motor 301 to mix the wood adhesive raw material overtime. During the stirring process, the cleaning plate 803 cleans the inner wall of the mixing box 1 during the rotation of the stirring rod 302, thereby preventing the wood adhesive from adhering to the inner wall of the mixing box 1, thereby ensuring the cleanliness of the inner wall of the mixing box 1 to a certain extent. When the cleaning mechanism 8 needs to clean the connecting rod 802 during long-term use, the personnel will remove the sealing cover on the top of the mixing box 1, then take out the stirring mechanism 3 from the inside of the mixing box 1, and then turn off the power to the electromagnet 2 804 to lose its magnetic force, so that the fixed sleeve 801 can be removed from the surface of the stirring rod 302, so that the cleaning plate 803 can be quickly disassembled and replaced. At the same time, the electromagnet 2 804 is electrically connected to the conductive slip ring through the stirring rod 302 wire, which can avoid the wire from being entangled, thereby ensuring the normal use of the device to a certain extent.

[0033] Working principle: When the device is mixing the wood adhesive, the wood adhesive raw material is added into the inner cavity of the mixing box 1 through the feeding mechanism 2. In the process of mixing the wood adhesive through the stirring mechanism 3, the interior of the mixing box 1 can be vacuumed by the vacuum pump 4, thereby reducing the generation of bubbles inside the wood adhesive during the stirring process. When the mixing and stirring of the wood adhesive is completed, the wood adhesive raw material will generate bubbles during the stirring process. When the personnel need to discharge the wood adhesive inside the mixing box 1 through the discharge pipe 7, at this time, the vibration motor 602 can be turned on by the external controller, and the filter plate 605 can be driven to vibrate through the output end of the vibration motor 602 to filter the wood adhesive discharged from the mixing box 1 through the discharge pipe 7, thereby reducing the bubbles inside the wood adhesive to a certain extent, avoiding excessive bubbles affecting the quality of the wood adhesive, and thereby improving the service life of the wood adhesive.

[0034] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
