Technical Field

[0001] This utility model belongs to the field of high-speed mixer technology, specifically relating to a multifunctional PP hollow board high-speed mixer. Background Technology

[0002] PP hollow board is a hollow structural board made of polypropylene as the main raw material through extrusion molding. It has a honeycomb cross-section and features lightweight, waterproof, moisture-proof, corrosion-resistant, non-toxic and environmentally friendly characteristics. It is widely used in packaging, logistics turnover, building formwork, advertising boards, refrigerator bottoms, etc. It can replace cardboard or metal sheets, reduce costs and improve environmental performance.

[0003] A high-speed mixer is a device that uses high-speed rotating blades to quickly shear, mix, and disperse materials. It is suitable for the uniform mixing of various materials such as powders, granules, and liquids, and is commonly used in industries such as plastics, chemicals, food, and pharmaceuticals to improve mixing efficiency and product quality.

[0004] In the production process of existing PP hollow boards, it is necessary to first mix raw materials such as PP resin, additives and fillers. Existing high-speed mixers tend to generate high temperatures during operation. Under high temperature (110 ℃) or excessive shear conditions, raw materials such as PP resin, flame retardant masterbatch, and calcium carbonate are prone to the phenomenon of "stickiness-agglomeration-caking", which causes the materials to stick to the inner wall of the mixer and affect the mixing quality. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional high-speed PP hollow board mixer that uses a cooling mechanism to cool the materials, prevent them from sticking together and clumping, and ensure the quality of the mixing.

Detailed Implementation

[0015] 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. Example

[0016] Please see Figure 1 - Figure 4 As shown, a multifunctional PP hollow board high-speed mixer includes: a mounting base 1, a mixing tank 2 connected to the mounting base 1 via a rotating assembly, an inlet and an outlet respectively opened on the outer walls of both ends of the mixing tank 2, an inlet and an outlet assembly provided at the inlet and outlet, a rotating rod 3 rotatably mounted on the inner wall of the mixing tank 2, multiple stirring assemblies provided on the rotating rod 3, a drive assembly provided on the mixing tank 2, and a cooling mechanism provided inside the mixing tank 2; The cooling mechanism includes an installation groove inside the mixing tank 2. The installation groove is circular. A heat-conducting plate 4 is fixedly installed on the inner side wall of the installation groove. The heat-conducting plate 4 is circular and located at the opening of the installation groove. A cooling pipe 5 is installed inside the installation groove. The outer side wall of the cooling pipe 5 is fixedly installed on the outer side wall of the heat-conducting plate 4. The cooling pipe 5 is spirally arranged.

[0017] As can be seen from the above, the mounting base 1 suspends the mixing barrel 2 through the rotating seats 9 on both sides and the connecting rod 10, forming a support frame that can tilt back and forth. The barrel wall of the mixing barrel 2 is embedded with a circular mounting groove, and the groove opening is sealed with a heat-conducting plate 4. The spiral cooling pipe 5 is close to the heat-conducting plate 4, and the cooling water circulation carries away the heat, thereby controlling the temperature inside the mixing barrel 2. The rotating rod 3 inside the barrel is directly driven by the second motor 19 through the drive rod 20. The roller 17 on the rod drives several stirring paddles 18 to rotate at high speed, stirring and mixing the materials, thereby improving the mixing effect of the materials. The barrel body is provided with a feed pipe 14 and a discharge pipe 15 at both ends, which can be rotated at a small angle under the drive of the first motor 12, the first gear 11 and the second gear 13, realizing the conversion of three postures: feeding, mixing and discharging. The barrel body tilting is synchronized with the rotation of the paddles, so that the materials form a three-dimensional tumbling, improving the mixing uniformity and reducing dead corners, improving the mixing quality of the materials and avoiding clumping. The mixing tank 2 is equipped with a temperature monitoring device (not shown in the figure) to facilitate monitoring of the temperature inside the mixing tank 2. By setting a temperature range, the cooling mechanism starts to work when the temperature is high (110 ℃) to cool down. When the temperature drops (<90 ℃), the cooling mechanism stops working, so that the temperature inside the mixing tank 2 is maintained between 90 ℃ and 110 ℃, thereby improving the mixing effect of the device.

[0018] Specifically, both ends of the cooling pipe 5's inlet and outlet pass through the mounting groove and extend upwards. A first connector 6 is fixedly installed at the cooling pipe 5's inlet, and a second connector 7 is fixedly installed at the cooling pipe 5's outlet.

[0019] As can be seen from the above, the first connector 6 makes it easy to connect the inlet of the cooling pipe 5 to the water inlet pipe, and the second connector 7 makes it easy to connect the outlet of the cooling pipe 5 to the water outlet pipe. The spirally arranged cooling pipe 5 is closely attached to the annular heat-conducting plate 4. Cooling water flows in from the first connector 6 and flows out from the second connector 7, forming a continuous cooling layer on the barrel wall. The heat-conducting plate 4 quickly transfers the heat inside the barrel to the cooling water for cooling.

[0020] Specifically, regarding the aforementioned rotating assembly, stirring assembly, and driving assembly, the rotating assembly includes a fixed ring 8 fixedly sleeved on the outer wall of the mixing tank 2. Rotating seats 9 are fixedly provided on the outer walls of both ends of the fixed ring 8. The ends of the two rotating seats 9 are rotatably connected to the inner wall of the mounting base 1. A connecting rod 10 is rotatably provided through the mounting base 1. The end of the connecting rod 10 is fixedly connected to the end of the rotating seat 9 at the corresponding position. A first gear 11 is fixedly provided on the end of the connecting rod 10. A first motor 12 is fixedly installed on the outer wall of the mounting base 1. A rotating shaft is fixedly installed at the output end of the first motor 12. A second gear 13 is fixedly installed at the end of the rotating shaft. The second gear 13 and the first gear 11 are meshed and connected. The stirring assembly includes a mounting roller 17 fixedly sleeved on the outer wall of the rotating rod 3, and a plurality of stirring paddles 18 are fixedly disposed on the outer wall of the mounting roller 17; The drive assembly includes a second motor 19 fixedly mounted on the outer wall of the mixing tank 2. A drive rod 20 is fixedly mounted on the output end of the second motor 19. The end of the drive rod 20 passes through the mixing tank 2 and is fixedly connected to the end of the rotating rod 3.

[0021] As can be seen from the above, the fixed ring 8 and the rotating seats at both ends 9 form an integral rotating shaft. The first motor 12 drives the second gear 13 to mesh with the first gear 11, which drives the connecting rod 10 and the rotating seat 9 to rotate synchronously at a small angle. The gear transmission torque is large and the positioning is accurate, so that the mixing tank 2 can smoothly switch between the three postures of feeding, mixing and unloading, without the need for manual handling of the tank, thus reducing labor intensity. The second motor 19 directly drives the rotating rod 3 via the drive rod 20. Multiple sets of stirring paddles 18 on the mounting roller 17 stir and mix the material. Combined with the tilting of the barrel, this forms a three-dimensional tumbling motion, resulting in uniform mixing of the material. Example

[0022] The feeding and discharging assembly includes a feed pipe 14 and a discharge pipe 15 respectively located at the feed inlet and the discharge outlet. The inner walls of the feed pipe 14 and the discharge pipe 15 are threaded with sealing cover plates 16.

[0023] As can be seen from the above, the feed pipe 14 and the discharge pipe 15 are located at both ends of the barrel, and both are equipped with threaded sealing cover plates 16 inside. Tightening them can seal the barrel, and loosening them can open it quickly. The pipe openings are linked to the tilting of the barrel, ensuring smooth feeding and thorough unloading, avoiding residue, reducing dust dispersion, and improving operational safety and cleanliness.

[0024] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
