[0021] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Example:

[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] A defoaming device for producing PUR glue for shoes includes a tank body 1, a sealing cover 2 is fixedly installed on the top of the tank body 1, a motor 3 is fixedly installed at the center of the top of the sealing cover 2, a pumping sleeve 4 is fixedly installed on the inner side of the sealing cover 2, an auger 5 is rotatably connected to the inside of the pumping sleeve 4, the top of the auger 5 is fixedly connected to the output end of the motor 3, a stirring frame 6 is fixedly installed on the bottom end of the auger 5, an air pump 7 is fixedly installed on the left end of the top of the sealing cover 2, a feeding barrel 8 is fixedly installed on the front end of the top of the sealing cover 2, a feeding hopper 9 is fixedly installed on the top of the feeding barrel 8, and a discharge pipe 10 is fixedly installed on the bottom end of the tank body 1.

[0025] First, a sealing gasket 201 is fixedly installed on the inner side of the sealing cover 2, and the outer side of the sealing cover 2 is fixedly connected to the tank body 1 through multiple sets of lock buckles 202. After the sealing cover 2 is closed, it is fixed to the tank body 1 through the lock buckles 202, and its sealing is ensured by the inner sealing gasket 201. When the inside of the tank body 1 needs to be cleaned, it is also convenient to open the sealing cover 2 for cleaning.

[0026] Furthermore, a feed port 401 is provided at the bottom end of the extraction sleeve 4, and two sets of discharge ports 402 are symmetrically provided at the top end of the extraction sleeve 4. The defoaming agent is added to the interior of the tank body 1, and then the auger 5 is driven to rotate by the motor 3. The PUR glue at the bottom end of the tank body 1 is drawn into the interior of the extraction sleeve 4 through the feed port 401, and finally lifted to the top end of the extraction sleeve 4 and discharged from the discharge port 402. When the auger 5 rotates, the stirring frame 6 rotates accordingly, so that the defoaming agent and the PUR glue are fully mixed together, thereby greatly improving the defoaming efficiency.

[0027] Then, two groups of first stirring paddles 501 are symmetrically connected to the bottom end of the auger 5 and above the stirring frame 6, and multiple groups of second stirring paddles 601 are symmetrically connected to the inner side of the stirring frame 6. The top of the stirring frame 6 is rotatably connected to the extraction sleeve 4 through a connecting ring 602. When the auger 5 rotates, the stirring frame 6 rotates accordingly for stirring, and at the same time, the first stirring paddle 501 and the second stirring paddle 601 are fully stirred, thereby improving the mixing effect of the defoaming agent and the PUR glue, and thereby improving the defoaming efficiency.

[0028] Furthermore, two groups of scrapers 603 are symmetrically connected to the outside of the stirring frame 6, and the upper and lower ends of the two groups of scrapers 603 are fixedly connected with connecting columns 604. The connecting columns 604 are slidingly connected to the stirring frame 6 through a connecting sleeve 605. One end of the connecting column 604 located inside the connecting sleeve 605 is movably installed with a spring 606. The spring 606 inside the connecting sleeve 605 can continuously push the connecting column 604 outward. When the stirring frame 6 rotates, the scraper 603 fits against the inside of the tank body 1 to prevent the PUR glue from adhering to the inner wall of the tank body 1, so that the PUR glue can be fully mixed with the defoaming agent.

[0029] Secondly, the input end of the vacuum pump 7 is connected to the interior of the tank body 1 through the vacuum pipe 701, and an exhaust pipe 702 is fixedly installed on the output end of the vacuum pump 7, and an electromagnetic valve 703 is installed on the exhaust pipe 702. When the PUR glue and the defoaming agent are fully mixed to remove bubbles, the electromagnetic valve 703 is opened to start the vacuum pump 7, and the bubbles exhausted through the vacuum pipe 701 are discharged through the exhaust pipe 702, so as to avoid the gas staying inside the tank body 1 and re-entering the PUR glue, thereby further improving the defoaming effect.

[0030] Finally, a material guide column 801 is installed inside the feed barrel 8, and a spiral material guide plate 802 is fixedly connected to the outside of the material guide column 801. Valves 901 are installed at the bottom ends of the feed hopper 9 and the discharge pipe 10. When the PUR glue is introduced into the interior of the tank body 1 through the feed hopper 9, after the PUR glue enters the interior of the feed barrel 8, a spiral flow channel is formed between the spiral material guide plate 802 and the feed barrel 8, preventing PUR from directly entering and thus reducing the entry of air. When debubbling the PUR glue, the valve 901 is closed to prevent external air from entering.

[0031] In this embodiment, the implementation scenario is specifically as follows: when defoaming the PUR glue, when the PUR glue is introduced into the interior of the tank body 1 through the feed hopper 9, after the PUR glue enters the interior of the feed barrel 8, a spiral flow channel is formed between the spiral guide plate 802 and the feed barrel 8 to prevent the PUR from directly entering, thereby reducing the entry of air. After the PUR glue is introduced into the interior of the tank body 1, the defoaming agent is introduced into the interior of the tank body 1, and then the auger 5 is driven by the motor 3 to rotate, and the PUR glue at the bottom end of the tank body 1 is drawn into the interior of the extraction sleeve 4 through the feed port 401, and finally lifted to the top of the extraction sleeve 4 and discharged from the discharge port 402. When the auger 5 rotates, the stirring frame 6 rotates accordingly, thereby fully mixing the defoaming agent and the PUR glue together. When the auger 5 rotates, the stirring frame 6 rotates accordingly to stir, and at the same time, the first stirring paddle 501 and the second stirring paddle 601 are used to fully stir, thereby improving the mixing effect of the defoaming agent and the PUR glue. When the stirring frame 6 rotates, the scraper 603 fits the inside of the tank body 1 to prevent the PUR glue from adhering to the inner wall of the tank body 1, so that the PUR glue can be fully mixed with the defoaming agent. The solenoid valve 703 is opened to start the air pump 7, and the bubbles exhausted by the air extraction pipe 701 are discharged through the exhaust pipe 702 to prevent the gas from staying inside the tank body 1 and re-entering the PUR glue. The entire operation process is simple and convenient. Compared with the existing PUR glue production defoaming method, the utility model greatly improves the defoaming efficiency through design.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
