[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-9 :

[0036] Example 1:

[0037] This embodiment provides a mixing and stirring device, including a stirring cylinder 1, wherein a first cavity 2 is provided inside the stirring cylinder 1, and a discharge port 3 is provided at the bottom of the stirring cylinder 1. The device is characterized by further comprising:

[0038] The stirring rod mechanism includes a stirring rod 4 disposed in the first cavity 2 and a first motor 5 disposed at the top of the stirring cylinder 1 for driving the stirring rod 4 to rotate. The stirring rod 4 includes multiple rods 11 arranged horizontally from top to bottom, and adjacent rods 11 are connected end to end.

[0039] Feeding pipe 6 is provided on both sides of the mixing drum 1 and is connected to the first cavity 2.

[0040] Additive tube 7 is disposed at the top of the stirring cylinder 1 and is connected to the first cavity 2;

[0041] The spiral conveying mechanism includes a feed pipe 8, a spiral conveying pipe and a discharge pipe 10 connected in sequence. The feed pipe 8 is connected to the discharge port 3. The spiral conveying pipe includes a pipe body 9, a spiral conveying blade 12 disposed in the pipe body 9 and a second motor 21 disposed at one end of the pipe body 9 for driving the spiral conveying blade 12 to rotate.

[0042] The mixing drum 1 is the main part of the entire mixing device and is used to contain the EVA material to be mixed. The mixing drum 1 is usually cylindrical or near-cylindrical in shape, with a first cavity 2 inside for storing the EVA material and a discharge port 3 at the bottom for discharging the mixed EVA material. The mixing drum 1 is located at the center of the device, and other components are arranged around it. The mixing drum 1 can be made of corrosion-resistant, high-temperature resistant stainless steel or fiberglass and other metal materials.

[0043] The stirring rod 4 rotates within the first cavity 2, powered by the first motor 5, to mix the EVA material in the mixing drum 1, ensuring uniform mixing of the EVA material and additives. The stirring rod 4 comprises multiple horizontally arranged rods 11 arranged from top to bottom, with adjacent rods 11 connected end-to-end. This structural design offers several advantages, primarily: the continuous stirring path formed by the multiple rods 11 covers a larger area within the mixing drum 1, ensuring thorough mixing at all levels and in all corners; the end-to-end connection of the rods 11 makes the stirring action more continuous and smooth, reducing blind spots and improving the uniformity and efficiency of the mixing; the sequential arrangement and connection of the multiple rods 11 form a stable structural frame, enabling the stirring rod 4 to maintain good stability during high-speed rotation. This structure also helps reduce vibration and noise during the mixing process, improving the equipment's service life and safety. The stirring rod 4 can be made of high-strength, corrosion-resistant alloy steel or stainless steel and other metal materials. The first motor 5 includes an output shaft 20, which extends from the top of the stirring drum 1 into the inside of the stirring drum 1 and can be threadedly connected to the external thread of the stirring rod 4 through the internal thread of the output shaft 20.

[0044] The feeding pipe 6 is used to transport the EVA material to be mixed from the outside into the mixing drum 1. The feeding pipe 6 is usually a tubular structure. The feeding pipe 6 includes a first pipe body 9 inclined to the central axis of the mixing drum 1 and a second pipe body 9 parallel to the central axis of the mixing drum 1. The first pipe body 9 and the second pipe body 9 are connected. The first pipe body 9 is connected to the side wall of the mixing drum 1. The inclined structure design allows the material to enter the mixing drum 1 smoothly. The structure design of the second pipe body 9 parallel to the central axis of the mixing drum 1 can be easily connected to an external feeding system. The feeding pipe 6 can be fixed to both sides of the mixing drum 1 by welding or threading, which facilitates feeding from multiple directions.

[0045] The additive tube 7 is used to add various additives into the mixing tank 1. The additive tube 7 is usually a tubular structure, but the diameter of the additive tube 7 is usually small to ensure accurate addition of additives. The additive tube 7 can be fixed to the top of the mixing tank 1 by welding or threading for easy operation and control.

[0046] The combination of the feeding pipe and the additive pipe allows the EVA material and additives to be mixed in the mixing drum, thereby improving the performance of the EVA material and obtaining higher quality EVA material.

[0047] The screw conveyor mechanism transports the mixed material discharged from the bottom outlet 3 of the mixing drum 1 to subsequent processing steps. The screw conveyor mechanism includes a feed pipe 8, a screw conveyor pipe, and a discharge pipe 10. The screw conveyor pipe contains screw conveyor blades 12. The feed pipe 8 is connected to the bottom outlet 3 of the mixing drum 1 and is used to transport the mixed material from the mixing drum 1 into the screw conveyor pipe. The screw conveyor pipe stably transmits the material from the feed pipe 8 to the discharge pipe 10 via the screw conveyor blades 12, and then the discharge pipe 10 completes the final discharge. The feed pipe 8, screw conveyor pipe, and discharge pipe 10 are typically tubular structures, and the materials of the feed pipe 8, screw conveyor pipe, and discharge pipe 10 can be the same as those of the aforementioned feeding pipe 6 and additive pipe 7. The screw conveyor blades 12 include blades and a rod 11. The rod 11 is fixed to the output shaft 20 of the second motor 21 via a coupling or pin.

[0048] Example 2:

[0049] This embodiment provides a mixing and stirring device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0050] The stirring rod mechanism also includes at least one wall-scraping stirrer;

[0051] The wall-scraping agitator includes a scraper 13 that fits tightly against the inner wall of the mixing drum 1 and a connecting arm for connecting the scraper 13 to the mixing rod 4. The wall-scraping agitator moves synchronously with the rotation of the mixing rod 4.

[0052] The wall scraper agitator is used to scrape off the material adhering to the inner wall of the mixing drum 1 during the mixing process, ensuring that the material is fully mixed and reducing residue, improving mixing efficiency and ensuring product quality. The wall scraper agitator consists of a scraper 13 and a connecting arm.

[0053] The scraper 13 directly contacts the inner wall of the mixing drum 1 to scrape off the material, ensuring uniform mixing and reducing material waste. The scraper 13 has an arc-shaped cross-section at one end and a square cross-section at the other. The arc-shaped end matches the shape of the inner wall of the mixing drum 1, allowing the scraper 13 to fit tightly against the inner wall, improving scraping efficiency. The scraper 13 is also polished to have smooth edges, reducing wear on the inner wall of the mixing drum 1. The square end provides a flat connecting surface, allowing the scraper 13 to be connected to the connecting arm via welding or threads. The connecting arm connects the scraper 13 to the mixing rod 4, serving as a connector between them. It transmits power to the scraper 13, ensuring synchronous movement between the scraper 13 and the mixing rod 4. The connecting arm can be a rod 11 with a circular cross-section. It can be connected to the mixing rod 4 via welding or threads. Both the scraper 13 and the connecting arm can be made of wear-resistant and corrosion-resistant stainless steel or alloy steel.

[0054] The stirring rod 4 rotates under the drive of the motor, which in turn drives the wall-scraping agitator to rotate synchronously. The scraper 13 is in close contact with the inner wall of the mixing drum 1, scraping off the material adhering to the wall, so that the material is in full contact with the stirring rod 4, achieving efficient mixing.

[0055] Example 3:

[0056] This embodiment provides a mixing and stirring device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0057] The bottom of the mixing drum 1 is designed as a cone structure, and a discharge port is provided at the lowest point of the cone structure. The discharge port is connected to the feed pipe 8.

[0058] The cone-shaped bottom of the mixing drum 1 helps the material gradually converge towards the center during the mixing process, which facilitates discharge, reduces residue, and improves production efficiency.

[0059] Example 4:

[0060] This embodiment provides a mixing and stirring device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0061] The first motor 5 is provided with a top motor housing 17 on its exterior, and the second motor 21 is provided with a bottom motor housing 18 on its exterior. The top motor housing 17 is connected to the top of the stirring drum 1, and the bottom motor housing 18 is connected to one end of the spiral conveying pipe.

[0062] The top motor housing 17 and the bottom motor housing 18 respectively protect the first motor 5 and the second motor 21 from external environmental influences such as dust and moisture. The top motor housing 17 and the bottom motor housing 18 are typically cuboids or cylinders, with internal cavities for housing the motors, and one end is open, with a mounting base 19 around the outer edge of the opening. The top motor housing 17 and the bottom motor housing 18 can be made of wear-resistant and corrosion-resistant stainless steel or alloy steel. The top motor housing 17 is connected to the top of the mixing drum 1, and the bottom motor housing 18 is connected to one end of the spiral conveying pipe. Both can be fixed with bolts or other fastening methods to ensure the stability of the motors during operation.

[0063] Example 5:

[0064] This embodiment provides a mixing and stirring device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0065] The top motor housing 17 and the bottom motor housing 18 each include a housing body 25. The top and bottom of the housing body 25 are respectively provided with a top plate 16 and a bottom plate 19. Both sides of the housing body 25 are provided with heat dissipation grilles. The front end of the housing body 25 is provided with a cabinet door 15. A ceramic heat sink 31 is also provided inside the housing body 25. The ceramic heat sink 31 is in close contact with the bottom of the motor.

[0066] The cabinet door (15) and the chassis body (25) are composed of a first noise-reducing aluminum plate (28), sound insulation cotton (29) and a second noise-reducing aluminum plate (30) on both sides.

[0067] The chassis body 25 protects the internal motor from external dust and moisture, improving its lifespan and safety. The chassis body 25 can be square or cylindrical, and can be made of aluminum alloy with excellent thermal conductivity to improve heat dissipation. The top plate 16 is tightly welded to the top of the chassis body 25, and its area is larger than the top area of ​​the chassis body 25 to prevent external moisture from sliding down the outer wall of the chassis body 25, reducing the possibility of water ingress. The bottom plate 19 is tightly welded to the bottom of the chassis body 25, and its area is larger than the bottom area of ​​the chassis body 25 for easy installation on adjacent components. The bottom plate 19 in the top motor housing 17 can be connected to the top of the mixing drum 1 by bolts or threads, and the bottom plate 19 in the bottom motor housing 18 can be connected to one end of the spiral conveying pipe by bolts or threads.

[0068] The heat dissipation grille is located on both sides of the chassis body 25. The heat dissipation grille can be composed of a series of protrusions 26 that slope downwards. The sloped design is more conducive to preventing the entry of external moisture. The protrusions 26 can be long strips, and the protrusions 26 have ventilation holes 27 that communicate with the chassis body 25. The ventilation holes 27 allow air to circulate, help dissipate heat from the motor, and prevent overheating. The heat dissipation grille can be integrally made with the chassis body 25.

[0069] Cabinet door 15 is used to open and close the motor housing for convenient maintenance and repair of the internal motor. One side of cabinet door 15 is rotatably fixed to the housing body 25 via a hinge connection. When it is necessary to close the motor housing, the other side of cabinet door 15 is fixed to the housing body 25 via a snap-fit ​​connection, thereby realizing the opening and closing of the motor housing. The first noise-reducing aluminum plate 28, sound insulation cotton 29, and the second noise-reducing aluminum plate 30 are used to reduce the noise emitted by the motor during operation. The three layers of noise-reducing materials can be fixed together sequentially using bolts or screws.

[0070] The ceramic heat sink 31 is a heat dissipation element made of a material with high thermal conductivity and high temperature resistance. One side of the ceramic heat sink 31 can be fixed to the bottom surface of the internal cavity of the chassis body 25 by adhesive, and the other side is in close contact with the bottom of the motor. It dissipates the heat generated by the motor to the surrounding air quickly through conduction and convection, so as to maintain the stable operation of the motor.

The distance between the two ends of the support leg 22 is greater than the distance from the bottom of the mixing drum 1 to the outlet of the discharge pipe 10.

[0075] The support frame mechanism provides stable support for the mixing drum 1, ensuring that it does not shake or tip over during operation. The support frame mechanism consists of multiple support legs 22. As the main load-bearing components of the support frame mechanism, the support legs 22 evenly distribute the weight of the mixing drum 1 onto the ground. The support legs 22 are typically solid or hollow tubular structures, and their shape is usually cylindrical or square for ease of processing and installation. One end of each support leg 22 is connected to the bottom of the mixing drum 1 by welding or bolts, while the other end contacts the ground. The support legs 22 can be made of wear-resistant and corrosion-resistant stainless steel or alloy steel.
