Description

Technical Field

[0001] This utility model relates to the field of rubber raw material impurity removal technology, specifically to a rubber injection molding machine with an impurity filtration mechanism. Background Technology

[0002] In the industrial production of rubber products, rubber injection molding machines, as core molding equipment, directly determine a company's production efficiency and market competitiveness through their processing efficiency and product quality. Furthermore, the purity of rubber raw materials, as the fundamental carrier in production, plays a crucial role in subsequent injection molding processes and the performance of the final product.

[0003] Currently, rubber raw materials (including natural rubber, synthetic rubber, reclaimed rubber, and various elastomers) are easily mixed with various impurities during procurement, transportation, storage, and pretreatment. These include metal shavings generated by wear and tear on vehicle metal parts during transportation, fibrous impurities introduced by damaged packaging materials during storage, unplasticized rubber lumps left by equipment during raw material cutting, and sand and gravel particles carried in during the recycling of reclaimed rubber. Because these impurities are smaller than the rubber raw materials, they are prone to wear and tear on internal components of the injection molding machine after entering it, and they are also prone to embedding in rubber products, thus affecting the quality of the rubber products.

Specifically, during the installation of the cover plate 3 by rotating the bolts, the screen cylinder 6 can be installed and fixed by the first support cover 7 and the second support cover 9. After a period of use, the screen cylinder 6 can be disassembled and replaced by disassembling the cover plate 3.

The side wall of the hopper 2 has an impurity removal port 11 with a built-in impurity removal control valve. The support pipe 12 is fixedly mounted on the bottom side wall of the cover plate 3, and its bottom end is sealed. The blower mechanism is mounted on the support pipe 12 and is used to blow air into the screen cylinder 6. The stirring assembly is mounted on the support pipe 12 and is used to stir the rubber raw material inside the screen cylinder 6. The rotating mechanism is mounted on the support plate 5 and is used to drive the discharge pipe 8 to rotate. The blower mechanism includes... The system includes an air inlet pipe 13 and an air duct. The air inlet pipe 13 is installed through and fixed on the cover plate 3. The air inlet pipe 13 extends into the support pipe 12. Multiple air ducts are provided on the side wall of the support pipe 12. A nozzle 14 is installed at the bottom of the air duct. The nozzle 14 is connected to the support pipe 12. Specifically, clean air can be blown into the support pipe 12 through the air inlet pipe. Then, air is blown into the filter cylinder through the nozzle 14 to form an airflow. At the same time, under the action of the airflow, small volume impurities in the rubber raw material can be blown out from the screen cylinder 6 and discharged through the impurity discharge port 11.

[0025] Reference Figures 3-5 The rotating mechanism includes scrapers 15 and stirring rods 16.

The side wall of the hopper 2 is provided with multiple heat dissipation holes on the side of the support plate 5 away from the cover plate 3. Specifically, the operation of the first motor 20 can drive the first gear 19 to rotate. At the same time, the meshing of the first gear 19 with the first gear ring 18 drives the feed pipe 8 and the first support cover 7 to rotate. At the same time, the friction between the first support cover 7 and the screen cylinder 6 drives the screen cylinder 6 and the rubber raw material to rotate. Thus, impurities can be thrown out of the screen cylinder 6 under the action of centrifugal force. During the rotation of the screen cylinder 6 and the rubber raw material, the rubber raw material can be stirred by the stirring rod 16 and the scraper 15, thereby improving the impurity removal efficiency.

[0026] In this embodiment, during use, the operator inserts the bottom end of the screen cylinder 6 into the first support cover 7 and then installs the box cover onto the hopper 2 with bolts. This allows the top end of the screen cylinder 6 to extend into the second support cover 9, and the first and second support covers 7 and 9 are used to position the screen cylinder 6. The operator then adds rubber raw material into the screen cylinder 6 through the hopper 2 and closes the feed control valve. Simultaneously, the operator blows clean air into the support pipe 12 through the air inlet pipe, and then blows air into the filter cylinder through the nozzle 14, forming an airflow. Under the action of the airflow, small-volume impurities in the rubber raw material are blown out of the screen cylinder 6 and discharged through the impurity discharge port 11. At the same time, the operator controls the first electric... When the machine 20 is working, the operation of the first motor 20 can drive the first gear 19 to rotate. At the same time, the meshing of the first gear 19 with the first gear ring 18 drives the feeding pipe 8 and the first support cover 7 to rotate. Simultaneously, the friction between the first support cover 7 and the screen cylinder 6 drives the screen cylinder 6 and the rubber raw material to rotate. Thus, under the action of centrifugal force, impurities can be thrown out from the screen cylinder 6. During the rotation of the screen cylinder 6 and the rubber raw material, the rubber raw material can be stirred by the stirring rod 16 and the scraper 15, thereby improving the impurity removal efficiency. After the impurities are removed, the feeding control valve can be opened, so that the rubber raw material can be fed into the injection molding machine body 1 through the feeding pipe 8 and the hopper 2.
