Description

Technical Field

[0001] This utility model relates to the field of granulation equipment technology, and in particular to a granulation device for EVA particle processing. Background Technology

[0002] A granulator is a molding machine that can shape materials into specific shapes. In the granulator, molten polymer strips are extruded and initially cooled by cooling water. Then the strips are pulled out and cut into granules by a cutter, and then cooled again to obtain the EVA granules used.

[0003] A search revealed Chinese patent CN221112479U, which discloses a granulation device for EVA particle processing. This patent uses a water tank structure to achieve cooling after EVA particle formation. However, because the EVA particles inside the water tank are difficult to remove, the efficiency of EVA particle granulation and cooling is reduced, which is detrimental to the continuous production of EVA particles. Therefore, in order to advance industry technology, better realize the cooling and conveying function of EVA particles after granulation, and improve core technological competitiveness, this application proposes a new implementation scheme that differs from the cooling and conveying structure and application method of existing granulation devices. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the use of existing granulation equipment, the EVA particles that have entered the water tank are not easy to remove, which leads to a decrease in the efficiency of EVA particle granulation and cooling, and is not conducive to the continuous production of EVA particles. Therefore, this invention proposes a granulation device for EVA particle processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A granulation device for EVA particle processing includes a granulator and a water tank. A conveying assembly is installed inside the water tank. The conveying assembly includes a guide shell, which is fixedly connected between the inner walls of both sides of the water tank. An inlet pipe and an outlet pipe are fixedly connected to the inlet and outlet ends of the guide shell, respectively. The top end of the inlet pipe is fixedly connected to the bottom of the outlet end of the granulator. Two rotating rollers are rotatably connected between the inner walls of the two sides of the guide shell. A first motor is fixedly connected to the top of one outer wall of the guide shell, and the output end of the first motor is connected to one end of one of the rotating rollers. A common conveyor belt is wound between the two rotating rollers. Multiple baffles are fixedly connected to the outer surfaces of the multiple conveyor belts, and one end of each baffle contacts the inner surface of the guide shell. A water-permeable mesh is fixedly fastened to the bottom of the guide shell, and the guide shell is connected to the water tank through the water-permeable mesh. A water level line is provided on one inner wall of the water tank.

[0007] Furthermore, a support base is placed on one side of the water tank, and the granulator is fixedly connected to the upper surface of the support base.

[0008] Furthermore, a screen box is placed on the other side of the water tank, and a connecting bucket is fixedly inserted into the top of the screen box, and the connecting bucket is fixedly connected to the bottom of the discharge pipe.

[0009] Furthermore, two screens are snapped between the inner walls of the screen box on multiple sides, and the screen aperture of the upper screen is larger than that of the lower screen.

[0010] Furthermore, the same guide hopper is fixedly connected between the multiple inner walls of the screen box, and the guide hopper is located between the two screens.

[0011] Furthermore, two storage boxes are placed on one side of the screen box, and a sealing door is snapped onto one side of each storage box. The feed ends of both storage boxes are fixedly connected to a conveying pipe, and the other end of the conveying pipe is fixedly connected to one side of the screen box.

[0012] Furthermore, a vibration motor is fixedly connected to the top of the screen box.

[0013] Furthermore, guide plates are fixedly connected to the upper surfaces of both screens. The two guide plates are located on one side of the corresponding guide hopper and connecting hopper, respectively, and the top view cross-section of the guide plates is a V-shaped structure.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Through the design of the material conveying component, which combines a conveyor belt and baffles, the cooled EVA particles in the guide shell can be conveyed, preventing the EVA particles from accumulating in the water tank. This ensures that the cooling operation after EVA particle production can be carried out continuously, thus guaranteeing the efficiency of EVA particle production.

[0016] 2. The screen design inside the sieve box allows for the screening of cooled EVA particles, enabling the collection of EVA particles within the same particle size range into the storage box. This facilitates the handling and packaging of the EVA particles by operators.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-5A granulation device for EVA particle processing includes a granulator 1 and a water tank 2. A support base 5 is placed on one side of the water tank 2, and the granulator 1 is fixed to the upper surface of the support base 5 by bolts. A material conveying assembly 3 is provided inside the water tank 2. The material conveying assembly 3 includes a guide shell 301, which is fixed between the inner walls of the two sides of the water tank 2 by bolts. A feed pipe 302 and a discharge pipe 303 are welded to the feed end and discharge end of the guide shell 301, respectively. The top end of the feed pipe 302 is fixed to the bottom of the discharge end of the granulator 1 by bolts. Two rotating rollers 304 are rotatably connected between the inner walls of the two sides of the guide shell 301. A first motor is fixed to the top of the outer wall of one side of the guide shell 301 by bolts, and the output end of the first motor is connected to one of the rotating rollers 304. The two rotating rollers 304 are connected at one end and the same conveyor belt 305 is wound around them. Multiple baffles 306 are bonded to the outer surface of the multiple conveyor belts 305, and one end of the baffle 306 contacts the inner surface of the guide shell 301. A water-permeable mesh cover 307 is fixedly clipped to the bottom of the guide shell 301, and the guide shell 301 is connected to the water tank 2 through the water-permeable mesh cover 307. A water level line 4 is set on one side of the inner wall of the water tank 2. Through the design of the material conveying component 3, the combination of the conveyor belts 305 and the baffles 306 can transport the cooled EVA particles in the guide shell 301, avoiding the EVA particles from accumulating in the water tank 2. This ensures that the cooling operation after EVA particle production can be carried out continuously, thus ensuring the efficiency of EVA particle production.

[0026] On the other side of the water tank 2, a screen box 6 is placed. A connecting hopper 8 is fixedly inserted into the top of the screen box 6, and the connecting hopper 8 is fixed to the bottom of the discharge pipe 303 by bolts. Two screens 7 are clamped between the inner walls of the multiple sides of the screen box 6, and the screen hole diameter of the upper screen 7 is larger than that of the lower screen 7. The same guide hopper 9 is fixed between the inner walls of the multiple sides of the screen box 6 by bolts, and the guide hopper 9 is located between the two screens 7. Through the combined design of the connecting hopper 8 and the guide hopper 9, the EVA particles entering the screen 7 can be guided within a certain range. At the same time, the V-shaped guide plate 14 can guide the particles that are rolled and screened on the screen 7, so that the EVA particles can be dispersed and screened by the screen 7, ensuring the practicality of the screen 7 for screening EVA particles.

[0027] Meanwhile, two storage boxes 10 are placed on one side of the sieve box 6. A sealing door 12 is snapped onto one side of the storage box 10. The feed end of both storage boxes 10 is fixedly connected to a conveying pipe 11, and the other end of the conveying pipe 11 is fixedly inserted through and connected to one side of the sieve box 6. Through the design of the sieve screen 7 inside the sieve box 6, the cooled EVA particles can be screened so that EVA particles within the same particle size range can be collected in the storage box 10, making it convenient for operators to take out and use the EVA particles for subsequent processing or packaging.

[0028] A vibration motor 13 is bolted to the top of the screen box 6. The vibration force of the vibration motor 13 is used to assist the conveying of EVA particles during the production process. Guide plates 14 are bolted to the upper surfaces of the two screens 7. The two guide plates 14 are located on one side of the corresponding guide hopper 9 and connecting hopper 8, respectively. The top view of the guide plate 14 is a V-shaped structure. The V-shaped guide plate 14 can disperse the EVA particles and improve the screening effect of the EVA particles.

[0029] The working principle of this embodiment is as follows: During use, operators can connect water pumps to both the inlet and outlet of water tank 2 to replace the cooling water in water tank 2, ensuring that the cooling water in water tank 2 cools the EVA particles at the correct temperature. Then, the operator first feeds the EVA raw material into granulator 1. Granulator 1 processes the EVA raw material through melting, extrusion, cooling, and cutting to form EVA particles. These particles then pass through the outlet of granulator 1, through the feed pipe 302, and into the guide shell 301. Simultaneously, the cooling water in water tank 2 enters the guide shell 301 through the water-passing mesh 307. The EVA particles falling into the guide shell 301 are cooled by the cooling water. After cooling, the EVA particles are conveyed from the bottom to the top of the guide shell 301 by conveyor belt 305 and baffle 306. When the material enters through the feed pipe 303, it passes through the discharge pipe 303 and the connecting hopper 8 into the screen box 6. Two screens 7 can screen EVA particles of different sizes, and the particles are then transported to the collection box 10 through the conveying pipe 11. The EVA particles are collected in the collection box 10, and then the operators can take out the EVA particles from the collection box 10 for further processing or packaging. At the same time, the vibration motor 13 is started during the EVA particle production and processing. The vibration force generated by the vibration motor 13 is transmitted to the screen box 6 and the screens 7 to facilitate the rolling of the EVA particles on the screens 7. Meanwhile, since the conveying component 3 is connected to the screen box 6 through the connecting hopper 8, the conveying component 3 will vibrate when the screen box 6 vibrates, so that the EVA particles in the conveying component 3 fall down. In this way, the EVA production and processing of the granulation device is completed.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
