[0054] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0055] like Figures 1-4As shown in the figure, this embodiment proposes a pressure kneading machine for conveyor belt production to reduce residual rubber in raw materials. It includes: a frame 1, kneading shafts 2, scrapers 3, scraping mechanism, ejection mechanism, rotation mechanism, and support mechanism. There are two kneading shafts 2, both of which are rotatably connected to the frame 1. There are two scrapers 3, which are located at the top of the two kneading shafts 2 respectively, and the two scrapers 3 are in contact with the circumferential surface of the two kneading shafts 2 respectively. Through the cooperation between the frame 1, kneading shafts 2, scrapers 3, scraping mechanism, ejection mechanism, rotation mechanism, and support mechanism, it is convenient to thoroughly clean the rubber raw materials adhering to the kneading shafts 2, and to collect the cleaned rubber raw materials for reuse, thereby reducing the waste of rubber raw materials.

[0056] The scraping mechanism is located inside the frame 1 and is used to scrape the rubber material on the kneading shaft 2. The scraping mechanism includes: a fixed frame 4, a connecting rod 5, a drive frame 6, a first electric cylinder 7, and a lifting assembly. A rotating rod 23 is fixedly connected to the fixed frame 4. A rotating hole is opened on the scraper 3, and the rotating rod 23 is rotatably connected in the rotating hole. The fixed frame 4 is located above the two scrapers 3, and both scrapers 3 are rotatably connected to the fixed frame 4. A connecting rod 5 is rotatably connected to both scrapers 3. The drive frame 6 is rotatably connected between the two connecting rods 5. The first electric cylinder 7 is installed on the fixed frame 4. The output end of the first electric cylinder 7 passes through the fixed frame 4 and is fixedly connected to the drive frame 6. The lifting assembly is located inside the frame 1 and is used to drive the fixed frame 4 to move up and down. The lifting assembly includes: a lifting frame 8 and a second electric cylinder 9. Two sliding rods 24 are fixedly connected to the frame 1. Two sliding holes are opened on the lifting frame 8, and the two sliding rods 24 are slidably connected in the two sliding holes respectively. The lifting frame 8 is slidably connected... Inside the frame 1, the fixed frame 4 is fixedly connected to the lifting frame 8. The second electric cylinder 9 is installed at the top of the frame 1, and the output end of the second electric cylinder 9 is fixedly connected to the lifting frame 8. Specifically, when the kneading shafts 2 rotate relative to each other, the two scrapers 3 contact the two kneading shafts 2 respectively, thereby scraping the rubber material on the surface of the kneading shafts 2 onto the scrapers 3. After scraping the rubber material on the kneading shafts 2, the first electric cylinder 7 installed on the fixed frame 4 drives the drive frame 6 and the two connecting rods 5 to rise, thereby driving the two scrapers 3 to rotate relative to each other around the rotating rod 23, so that the bottom ends of the two scrapers 3 contact each other, and the two scrapers 3 form a triangle. The rubber material adheres to the side of the two scrapers 3 that is far away from each other. Then, the second electric cylinder 9 drives the lifting frame 8 and the fixed frame 4 to rise, thereby driving the two scrapers 3 to rise, thereby moving the two scrapers 3 away from the two kneading shafts 2. After the scrapers 3 rise, it will not affect the normal use of the kneading shafts 2.

[0057] The ejection mechanism is mounted on the frame 1 and is used to eject the rubber material on the scraper 3. The ejection mechanism includes: a fixed rod 10, a slide plate 11, a moving rod 12, a scraping frame 13, and a drive assembly. One end of the fixed rod 10 is fixedly connected to the frame 1, the slide plate 11 is slidably connected to the fixed rod 10, one end of the moving rod 12 is fixedly connected to the slide plate 11, a sliding hole is provided on the frame 1, the moving rod 12 is slidably connected in the sliding hole, and the scraping frame 13 is fixedly connected to the other end of the moving rod 12. The drive assembly is mounted on the fixed rod 10 and is used to drive the slide plate 11 to move. The drive assembly includes: a motor plate 14, a moving screw 15, and a first motor 16. The motor plate 14 is fixedly connected to the fixed rod 10. At the other end of rod 10, a movable screw 15 is rotatably connected between motor plate 14 and frame 1. A screw hole is provided on slide plate 11, and movable screw 15 is threaded into the screw hole. First motor 16 is mounted on motor plate 14. The output end of first motor 16 passes through motor plate 14 and is fixedly connected to movable screw 15. Specifically, the first motor 16 mounted on motor plate 14 drives movable screw 15 to rotate. When movable screw 15 rotates, it drives slide plate 11 and movable rod 12 to move. When movable rod 12 moves, it drives scraper 13 to move. When scraper 13 moves, it pushes the rubber material on the two scrapers 3 to the edge of scraper 3, making it convenient for operators to clean the rubber material.

[0058] The rotating mechanism is mounted on the frame 1 and is used to drive the kneading shafts 2 to rotate. The rotating mechanism includes a rotating gear 17, a stabilizing frame 18, and a power component. The rotating gear 17 is fixedly connected to both kneading shafts 2 and meshes with each other. The stabilizing frame 18 is fixedly connected to the frame 1. The power component is mounted on the stabilizing frame 18 and is used to drive the rotating gears 17 to rotate. The power component includes a driving gear 19 and a second motor 20. The driving gear 19 is rotatably connected to the stabilizing frame 18, and the second motor 20 is mounted on the stabilizing frame 18. The output end of the second motor 20 passes through the stabilizing frame 18 and is fixedly connected to the driving gear 19. Specifically, the second motor 20 mounted on the stabilizing frame 18 drives the driving gear 19 to rotate. When the driving gear 19 rotates, it drives the two rotating gears 17 to rotate relative to each other, thereby driving the two kneading shafts 2 to rotate relative to each other, thus kneading the rubber raw material.

[0059] The support mechanism is mounted on the frame 1 to support the kneading shaft 2. The support mechanism includes a support frame 21 and support wheels 22. The support frame 21 is fixedly connected inside the frame 1. Multiple support wheels 22 are provided and are rotatably connected to the support frame 21. The two kneading shafts 2 are in contact with each of the two adjacent support wheels 22. Specifically, the support wheels 22 rotatably connected to the support frame 21 support one end of the kneading shaft 2, thereby supporting the kneading shaft 2 to rotate stably.

[0060] In this embodiment, when the rubber raw material needs to be kneaded, the second motor 20 installed on the stabilizer 18 drives the drive gear 19 to rotate. When the drive gear 19 rotates, it drives the two rotating gears 17 to rotate relative to each other, thereby driving the two kneading shafts 2 to rotate relative to each other, thus kneading the rubber raw material. After the rubber raw material adheres to the kneading shafts 2, the second electric cylinder 9 drives the lifting frame 8 and the fixed frame 4 to descend, causing the two scrapers 3 to descend and contact the two kneading shafts 2 respectively. When the kneading shafts 2 rotate relative to each other, since the two scrapers 3 contact the two kneading shafts 2 respectively, the rubber raw material on the surface of the kneading shafts 2 is scraped onto the scrapers 3. After the rubber raw material on the kneading shafts 2 is scraped off, the first electric cylinder 7 installed on the fixed frame 4 drives the drive frame 6 and the two connecting rods 5 to rise, thereby driving the kneading shafts 2 to rotate relative to each other. The two scrapers 3 rotate relative to each other around the rotating rod 23, so that the bottom ends of the two scrapers 3 contact each other and form a triangle. The rubber material adheres to the side of the two scrapers 3 that is far away from each other. Then, the second electric cylinder 9 drives the lifting frame 8 and the fixed frame 4 to rise, thereby driving the two scrapers 3 to rise and move them away from the two kneading shafts 2. After the scrapers 3 rise, it will not affect the normal use of the kneading shafts 2. The first motor 16 installed on the motor plate 14 drives the moving screw 15 to rotate. When the moving screw 15 rotates, it drives the slide plate 11 and the moving rod 12 to move. When the moving rod 12 moves, it drives the scraping frame 13 to move. When the scraping frame 13 moves, it pushes the rubber material on the two scrapers 3 to the edge of the scrapers 3, making it convenient for the operator to clean the rubber material.

[0061] It should also be noted that both the first motor 16 and the second motor 20 are reversible motors.

[0062] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
