Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, specifically a hot melt adhesive mixing tank. Background Technology

[0002] In the hot melt adhesive production process, the raw materials for hot melt adhesive are put into a mixing tank. The raw materials are in granular form. After being put into the mixing tank, the geared motor is started to rotate, and then heating is carried out. Heating and stirring are carried out at the same time, which can improve the efficiency of hot melt mixing.

[0003] During the mixing process, the raw material particles stick together with the melted particles when they are first heated, which can cause the motor to overload. At the same time, after the hot melt adhesive is completely mixed, the temperature drops rapidly, causing the hot melt adhesive to solidify quickly, which can also cause the motor to overload. After the material is discharged, it is difficult to clean the hot melt adhesive on the traditional mixing rod.

[0004] Existing technologies use a single mixing structure, which cannot break up the flow in layers, thus affecting mixing efficiency and equipment lifespan. Utility Model Content

[0008] Furthermore: an overlapping plate is fixed to the inner side of the flow-breaking plate, the overlapping plates are staggered and fixed by screws, and the components between the horizontal plate and the flow-breaking plate can be disassembled and assembled.

[0009] Furthermore, the cross-section of the horizontal plate and the flow-breaking plate of the flow-breaking mechanism is cross-shaped, and the connecting end is a conical structure.

[0010] Furthermore, the outer end face of the scraper fits and matches the inner wall of the tank, and the scraper contacts and abuts against the inner wall of the tank.

[0011] Furthermore, the stirring rod is arranged in a stepped spiral pattern and fixed on the outside of the middle fixing ring.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-7 This utility model provides a technical solution: a hot melt adhesive mixing tank; including a tank body 1 and a geared motor 2. The geared motor 2 is fixed on the tank cover of the tank body 1. A rotating rod 3 is fixedly connected to the output end of the geared motor 2. The rotating rod 3 extends into the interior of the tank body 1. Three equally spaced fixing rings 4 are fixed on the side wall of the rotating rod 3 inside the tank body 1. A flow-breaking mechanism is provided on the outer wall of the upper and lower fixing rings 4. A stirring rod 5 is provided on the outer wall of the middle fixing ring 4. The stirring rod 5 is arranged in a stepped spiral. The stirring rod 5 arranged in this way can drive the stirring of the middle layer of hot melt adhesive. The flow-breaking mechanism can break and agitate the hot melt adhesive at the upper and lower ends. The flow-breaking and agitation can reduce the load on the geared motor 2 and avoid overloading the geared motor 2 when the raw materials are piled up before heating and when the hot melt adhesive flows at low speed after heating, thereby extending the service life of the geared motor 2.

[0024] The flow-breaking mechanism includes a fixed base 6, which is fixed to the side wall of the fixed ring 4. A fixed rod 7 is fixedly connected to the outer side wall of the fixed base 6. Mounting grooves 11 are provided on both sides of the side wall of the fixed rod 7. Mounting holes 10 are provided at the upper end of the fixed rod 7. Horizontal plates 12 are provided on both sides of the fixed rod 7. The ends of the horizontal plates 12 protrude and are matched and inserted into the mounting grooves 11. The horizontal plates 12 and the fixed rod 7 are fixed by screws through the mounting holes 10. A fixed plate 8 is fixed to the end of the fixed rod 7. The fixed plate 8 is also fixed to the fixed base 6 by screws. Flow-breaking plates 13 are fixed to the upper and lower ends of the horizontal plates 12. The cross-sections of the horizontal plates 12 and the flow-breaking plates 13 are cross-shaped, and the connecting ends of the horizontal plates 12 and the flow-breaking plates 13 are tapered. This allows an impact end to be formed during rotation, creating a tapered impact with the hot melt adhesive, thereby breaking the flow and reducing the load on the geared motor 2.

[0025] A plate 9 is fixedly connected to the outer end of the fixing rod 7. A scraper 17 is provided on the outer side of the plate 9. A connecting seat 15 is fixed on the scraper 17. A slot 16 is provided on the connecting seat 15. The plate 9 is inserted into the slot 16 and fixed by a screw. The scraper 17 rotates with the rotation of the fixing rod 7, scraping the hot melt adhesive on the side wall of the tank 1 into the tank 1 for stirring.

[0026] The inner side of the flow-breaking plate 13 is matched with the fixing rod 7. An overlapping plate 14 is fixed at the connecting end of the flow-breaking plate 13. The overlapping plates 14 are staggered and overlapped and fixed by screws, so that the whole can be assembled. After stirring the hot melt adhesive, the inner tank 1 is cleaned. During cleaning, the flow-breaking mechanism is removed from the fixing ring 4 and further disassembled and removed, which is conducive to cleaning and storage.
