Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane glue production equipment, in particular to a polyurethane glue mixing tank. Background Technique

[0002] Polyurethane heat-insulating glue not only ensures high-quality mechanical strength and bonding strength, but also has a certain toughness. Its coefficient of thermal expansion is close to that of aluminum alloy profiles. Therefore, it can replace forms such as rivets and bolts for the connection of aluminum profiles.

[0003] The existing technology has the following problems:

[0004] After retrieval, Chinese Patent Publication No.: CN218872185U discloses a production device for high-strength polyurethane heat-insulating glue, including a mixing tank. A mixing rod is rotatably connected inside the mixing tank. A rotating motor is fixedly connected to the middle of the upper end of the mixing tank. The output rotating shaft of the rotating motor is fixedly connected to the top of the mixing rod. A containing component is embedded in the top of the mixing tank. Under the action of heat, the lifting column rises and the sealing ring leaves the bottom of the inner wall. TDI in the storage tank flows into the mixing tank through the gap between the inner and outer diffusion pipes under the action of gravity and is mixed with polyester, thus automatically completing the process of adding TDI, and without using any electric control device, it is more environmentally friendly and energy-saving, and improves reliability.

[0005] However, there are still problems to be improved in the actual use of the above patent. Obviously, the single mixing rod can only rotate in a single direction, resulting in an unsatisfactory mixing effect of polyurethane glue and additives during the mixing process, and the mixing efficiency needs to be improved.

[0006] Therefore, we propose a polyurethane glue mixing tank to solve the above disadvantages. Content of the Utility Model

[0027] Please refer to Figures 1-5, Polyurethane glue mixing tank, including a mixing tank 1. A guide rod 7 is welded to the top surface of the mixing tank 1, and a carrier 6 is slidably connected to the guide rod 7. A stirring motor 11 is installed on the carrier 6, and a first bevel gear 12 is installed at the output end of the stirring motor 11. A rack 8 is installed on one side of the carrier 6. An upper end of the outer wall of the mixing tank 1 is installed with a driving motor 9, and a gear 10 is installed at the output end of the driving motor 9, and the gear 10 meshes with the rack 8. A first stirring rod 4 is vertically arranged inside the mixing tank 1, and one end of the first stirring rod 4 passes through the top surface of the mixing tank 1 and is fixed to the carrier 6. A second stirring rod 5 is arranged through the inside of the first stirring rod 4, and one end of the second stirring rod 5 is installed on the carrier 6.

Support cylinders 16 are welded on both the first stirring rod 4 and the second stirring rod 5, and a spring 17 is installed on the inner wall of the support cylinder 16, and the other end of the spring 17 is installed with a limit block 18. A sliding rod 19 is arranged through the surface of the support cylinder 16, and a scraping plate 20 is installed at one end of the sliding rod 19, and the surface of the scraping plate 20 is elastically attached to the inner wall of the mixing tank 1. The other end of the sliding rod 19 extends into the support cylinder 16 and is connected to the limit block 18. When in use, polyurethane glue and additives are added into the mixing tank 1 together (it should be noted here that the mixing tank is a commercially available mixing tank for producing polyurethane glue, and the model is relatively common, so the specific structure of the mixing tank will not be described here), and then the stirring motor 11 and the driving motor 9 are started. The first stirring rod 4 and the second stirring rod 5 are installed on the carrier 6. The stirring motor 11 drives the first bevel gear 12 to rotate. The rotation of the first bevel gear 12 drives the second bevel gear 13 and the third bevel gear 14 engaged with it to rotate in the opposite direction. At this time, the reverse rotation of the second bevel gear 13 and the third bevel gear 14 respectively drives the first stirring rod 4 and the second stirring rod 5 to rotate in the opposite direction. At the same time, the driving motor 9 drives the gear 10 to rotate forward and backward. The forward and backward rotation of the gear 10 drives the rack 8 to move up and down. The up and down movement of the rack 8 drives the carrier 6 to move up and down accordingly, realizing the mixing and stirring of polyurethane glue and additives while moving up and down, expanding the mixing and stirring range of polyurethane glue and additives, with strong practicability and worthy of promotion. Secondly, under the elastic force of the spring 17, the scraping plate 20 can be always elastically attached to the inner wall of the mixing tank 1 well, so that polyurethane glue is not easy to remain on the inner wall of the mixing tank 1 during discharging, the discharging is cleaner and more thorough, and it is convenient for subsequent cleaning.

[0028] In this embodiment: A control panel 15 is fixedly installed on the outer wall of the mixing tank 1, and the control panel 15 is electrically connected to the stirring motor 11 and the driving motor 9 through wires.

[0029] Specifically, it is a common circuit connection structure and will not be elaborated here.

It belongs to the common knowledge in this field. Only its use is carried out without modification, so the control method and circuit connection will not be described in detail.

[0039] Working principle: During use, the polyurethane glue and the additive are added into the blending tank 1 together, and then the stirring motor 11 and the driving motor 9 are started. The first stirring rod 4 and the second stirring rod 5 are installed on the carrier 6. The stirring motor 11 drives the first bevel gear 12 to rotate. The rotation of the first bevel gear 12 drives the second bevel gear 13 and the third bevel gear 14 engaged with it to rotate in the opposite direction. At this time, the reverse rotation of the second bevel gear 13 and the third bevel gear 14 respectively drives the first stirring rod 4 and the second stirring rod 5 to rotate in the opposite direction. At the same time, the driving motor 9 drives the gear 10 to rotate forward and backward. The forward and backward rotation of the gear 10 drives the rack 8 to move up and down. The up and down movement of the rack 8 drives the carrier 6 to move up and down accordingly. While mixing and stirring the polyurethane glue and the additive, it moves up and down at the same time, expanding the stirring and mixing range of the polyurethane glue and the additive. It has strong practicability and is worthy of promotion. Secondly, under the elastic force of the spring 17, the scraper 20 can be pushed to always maintain a good elastic fit with the inner wall of the blending tank 1, so that the polyurethane glue is not easily left on the inner wall of the blending tank 1 during discharging, the discharging is cleaner and more thorough, and it is convenient for subsequent cleaning.
