Description

Technical Field

[0001] This utility model relates to the field of pre-dispersed masterbatch production technology, and in particular to a production apparatus for pre-dispersed masterbatch. Background Technology

[0002] This utility model, with publication number CN216732520U, relates to the field of masterbatch extrusion granulation technology, specifically to a pre-dispersed rubber additive masterbatch extrusion granulation device. It includes an extruder body, with an arc-shaped support block fixed to the right wall of the extrusion end. Two support blocks are fixed to the upper right wall of the extruder body in a symmetrical front-to-back structure, with a groove inside the right end of each support block. This utility model uses the extruder body to form pre-dispersed rubber additive masterbatch into cylindrical strips. A motor drives a pulley and belt at the lower end to rotate, causing a crankshaft to move a connecting rod up and down, pushing a cutter to granulate the cylindrical strips into masterbatch granules. The granulated masterbatch granules fall into a water tank for cooling. The granules are then conveyed to the right end via a conveyor belt and filter blocks, and after passing through a C-shaped baffle, fall into a drying chamber for drying. This design makes granulation more convenient, ensures timely cooling to effectively protect the integrity of the masterbatch granules, improves the production quality of the masterbatch granules, and significantly enhances their performance.

[0003] After searching, it was found that the existing technology has certain defects. The rubber strip is not completely cooled and shaped after being extruded from the extruder, and the pelletizing operation is prone to sticking to the blade, which affects the formation of pre-dispersed masterbatch granules. In addition, the reciprocating pelletizing motion of the cutter is inefficient and the output is low. Therefore, a production device for pre-dispersed masterbatch granules is needed to meet people's needs. Summary of the Invention

[0004] The purpose of this invention is to provide a production apparatus for pre-dispersed masterbatch particles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a production device for pre-dispersed masterbatch granules, comprising an extruder and a cooling water tank. The cooling water tank is arranged on one end of the extruder. A first motor is arranged on the outside of the cooling water tank. A first extrusion roller is connected to the output shaft of the first motor. A first gear is connected to one end of the first extrusion roller. The first gear is arranged on the outside of the cooling water tank. A second gear meshes with the first gear. A second extrusion roller is connected to the second gear. The second extrusion roller is rotatably connected inside the cooling water tank and arranged parallel to the first extrusion roller. Several corresponding grooves are provided on the outer walls of both the first and second extrusion rollers. A second motor is arranged on the outside of the cooling water tank. A transmission roller is connected to the output end of the second motor. The transmission roller is rotatably connected to the bottom of the cooling water tank. A driven roller is rotatably connected above the cooling water tank. A conveyor belt is connected between the driven roller and the transmission roller. Several holes are provided on the conveyor belt.

[0006] Preferably, the first extrusion roller, the second extrusion roller, and the drive roller are all sealed to the cooling water tank.

[0007] Preferably, a plurality of guide rollers are rotatably connected in the cooling water tank. The plurality of guide rollers are arranged between the extrusion end of the extruder and the first extrusion roller, and each pair of adjacent guide rollers are arranged with a vertical height difference.

[0008] Preferably, each of the guide rollers has several annular grooves on its outer wall.

[0009] Preferably, the cooling water tank is provided with a first scraper and a second scraper, both of which are arranged between the first extrusion roller and the conveyor belt. The first scraper is tangent to the first extrusion roller, and the second scraper is tangent to the second extrusion roller. The first scraper and the second scraper are arranged symmetrically.

[0010] Preferably, the outer wall of the conveyor belt is provided with a plurality of push plates, which are arranged perpendicular to the conveying direction of the conveyor belt and are arranged at equal intervals.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, a first motor drives a first extrusion roller to rotate, causing a first gear to rotate synchronously in the same direction. Through the meshing effect between the first and second gears, a synchronous relative rotation effect is generated between the second and first extrusion rollers. This causes the opposing grooves on the first and second extrusion rollers to compress the rubber strip extruded by the extruder, thereby achieving the granulation and forming effect of pre-dispersed masterbatch. Furthermore, by designing the first and second extrusion rollers inside a cooling water tank, a cooling effect is achieved after the rubber strip is extruded, as well as a granulation and forming effect after cooling. Compared with the prior art, this invention ensures the forming quality of the pre-dispersed masterbatch while increasing the output. Attached Figure Description

[0019] 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.

[0020] Reference Figure 1-4 A production apparatus for pre-dispersed masterbatch includes an extruder 1 and a cooling water tank 2. The cooling water tank 2 is arranged on one end of the extrusion of the extruder 1. A first motor 3 is arranged on the outside of the cooling water tank 2. A first extrusion roller 4 is connected to the output shaft of the first motor 3. A first gear 5 is connected to one end of the first extrusion roller 4. The first gear 5 is arranged on the outside of the cooling water tank 2. A second gear 6 meshes with the first gear 5. A second extrusion roller 7 is connected to the second gear 6. The second extrusion roller 7 is rotatably connected inside the cooling water tank 2 and is arranged parallel to the first extrusion roller 4. Several corresponding grooves 8 are provided on the outer walls of both the first extrusion roller 4 and the second extrusion roller 7. A second motor 9 is arranged on the outside of the cooling water tank 2. A transmission roller 10 is connected to the output end of the second motor 9. The transmission roller 10 is rotatably connected to the bottom end of the cooling water tank 2. A driven roller 11 is rotatably connected above the cooling water tank 2. A conveyor belt 12 is connected between the driven roller 11 and the transmission roller 10. Several holes are opened on the conveyor belt 12.

[0021] After the extruder 1 extrudes the rubber strip, it is cooled in the cooling water tank 2. The first motor 3 drives the first extrusion roller 4 to rotate, and the first gear 5 rotates synchronously in the same direction. Through the meshing effect between the first gear 5 and the second gear 6, the second extrusion roller 7 and the first extrusion roller 4 generate a synchronous relative rotation effect. The corresponding grooves 8 on the first extrusion roller 4 and the second extrusion roller 7 squeeze and cut the rubber strip, thereby turning the rubber strip into granules and realizing the granulation effect of pre-dispersed masterbatch. After granulation, the second motor 9 continuously drives the transmission roller 10 to rotate. With the support of the driven roller 11, the conveyor belt 12 with holes is used to transport the pre-dispersed masterbatch in the cooling water tank 2 from the water in an inclined manner from bottom to top, while draining some of the water. Compared with the prior art, this ensures the molding quality of the pre-dispersed masterbatch and increases the output.

[0022] Specifically, in this embodiment, the first extrusion roller 4, the second extrusion roller 7, and the transmission roller 10 are all sealed to the cooling water tank 2 to prevent water leakage at the rotating connection.

[0023] Specifically, in this embodiment, a number of guide rollers 13 are rotatably connected inside the cooling water tank 2. The guide rollers 13 are arranged between the extrusion end of the extruder 1 and the first extrusion roller 4. Each pair of adjacent guide rollers 13 are arranged with a vertical height difference, which causes the rubber strip to bend. This effectively increases the travel of the rubber strip in the cooling water tank 2, extends the cooling time, and ensures that the rubber strip is completely cooled and hardened.

[0024] Specifically, in this embodiment, each guide roller 13 has several annular grooves 14 on its outer wall to prevent contact between multiple rubber strips and ensure that each strip can achieve an independent cooling effect.

[0025] Specifically, in this embodiment, a first scraper 15 and a second scraper 16 are provided in the cooling water tank 2. The first scraper 15 and the second scraper 16 are both arranged between the first extrusion roller 4 and the conveyor belt 12. The first scraper 15 is tangent to the first extrusion roller 4, and the second scraper 16 is tangent to the second extrusion roller 7. The first scraper 15 and the second scraper 16 are symmetrically arranged, which helps to scrape out the pre-dispersed masterbatch particles stuck in the grooves 8 on the first extrusion roller 4 and the second extrusion roller 7, and prevents them from occupying the space of the grooves 8 during the cyclic rotation.

[0026] Specifically, in this embodiment, a plurality of push plates 17 are provided on the outer wall of the conveyor belt 12. The push plates 17 are arranged perpendicular to the conveying direction of the conveyor belt 12, and the plurality of push plates 17 are arranged at equal intervals. The circulation of the push plates 17 on the conveyor belt 12 can effectively prevent the pre-dispersed masterbatch particles from sliding down the conveyor belt 12.

[0027] Specifically, in this embodiment, a circulating water tank 18 is provided below the cooling water tank 2, and a water pump 19 is provided in the circulating water tank 18. The outlet end of the water pump 19 is connected to the bottom end of the cooling water tank 2. A drain pipe 20 is provided at the bottom end of the cooling water tank 2. The drain pipe 20 extends into the circulating water tank 18, and a valve 21 is provided on the drain pipe 20, which realizes the flow and circulation effect of cooling water in the cooling water tank 2 and prevents the cooling water from accumulating heat and reducing the cooling effect.

[0028] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
