Description

Technical Field

[0001] This utility model relates to the field of rubber extruder technology, and in particular to a twin-screw feeding mechanism for a rubber extruder. Background Technology

[0002] Rubber extruders are a basic piece of equipment in the rubber industry, mainly used in the production of tires and rubber products, and have a key impact on product quality.

[0003] In operation, rubber extruders utilize a twin-screw feeding mechanism to convey materials. This mechanism uses the rotation of two screws to propel the material, calculating the flow rate based on the rate at which the material decreases per unit time. In existing technologies, most twin-screw feeding mechanisms involve pouring material into a feeding hopper, from which it falls into the twin-screw feeding channel. When rubber material is poured into the hopper, accumulation can easily clog the hopper's outlet, preventing normal material flow and thus hindering feeding into the rubber extruder. This results in insufficient practicality. Therefore, a new twin-screw feeding mechanism for rubber extruders needs to be designed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a twin-screw feeding mechanism for a rubber extruder.

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

[0006] A twin-screw feeding mechanism for a rubber extruder includes a mounting plate. A feeding channel is fixedly mounted on the upper surface of the mounting plate. A feeding hopper communicating with the interior is fixedly mounted on the upper surface of the feeding channel. A drive shaft is rotatably mounted inside the feeding hopper. A motor connected to the drive shaft is fixedly mounted on the outer wall of the feeding hopper via a support mechanism. A rotating shaft is rotatably mounted inside the feeding hopper via a connecting plate. Both the rotating shaft and the drive shaft have bevel gears fixedly mounted on their outer walls, and the two bevel gears mesh perpendicularly. Multiple stirring rods are fixedly mounted on the outer wall of the rotating shaft via the mounting mechanism. A first connecting block and a second connecting block are fixedly mounted on the outer wall of the rotating shaft. A first scraper is fixedly connected to both outer walls of the first connecting block via a first connecting mechanism. A second scraper is fixedly connected to both outer walls of the second connecting block via a second connecting mechanism.

[0007] Preferably, the support mechanism includes a support plate fixedly installed on the outer wall of the feeding hopper, and the motor is fixedly installed on the outer wall of the support plate.

[0008] Preferably, the mounting mechanism includes a mounting sleeve fixedly mounted on the outer wall of the rotating shaft, and each of the stirring rods is fixedly mounted on the outer wall of the mounting sleeve.

[0009] Preferably, the first connecting mechanism includes a first connecting rod fixedly installed on the outer wall of the first connecting block, and the end of the first connecting rod is fixedly connected to the outer wall of the first scraper.

[0010] Preferably, the second connecting mechanism includes a second connecting rod fixedly installed on the outer wall of the second connecting block, and the end of the second connecting rod is fixedly connected to the outer wall of the second scraper.

[0011] Preferably, an air pump is fixedly installed on the upper end face of the feeding hopper via a support frame, an air extraction hood is fixedly installed on the outer wall of the air pump inlet pipe, and a dust collector bag is fixedly installed on the outer wall of the air pump outlet pipe.

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

[0013] 1. By setting up components such as bevel gears, rotating shafts, mounting sleeves, and stirring rods, the drive shaft can drive the rotating shaft to rotate through two vertically meshing bevel gears. The rotating shaft, in turn, drives multiple stirring rods to rotate through the mounting sleeves. This allows multiple stirring rods to stir the rubber material inside the feeding hopper, thereby preventing a large amount of rubber material from accumulating inside the feeding hopper and causing blockage.

[0014] 2. By setting up components such as an air pump, an air extraction hood, and dust collection bags, the air pump, in conjunction with the air extraction hood, can extract dust from the air and discharge it into the dust collection bags. The dust collection bags can intercept and filter the dust, thereby preventing a large amount of dust from floating in the air and affecting the health of the operators. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Reference Figure 1-5 A twin-screw feeding mechanism for a rubber extruder includes a mounting plate 1. A feeding channel 2 is fixedly mounted on the upper surface of the mounting plate 1. A feeding hopper 3 communicating with the inside is fixedly mounted on the upper surface of the feeding channel 2. A drive shaft 4 is rotatably mounted inside the feeding hopper 3. A motor 6 connected to the drive shaft 4 is fixedly mounted on the outer wall of the feeding hopper 3 through a support mechanism. The support mechanism includes a support plate 5 fixedly mounted on the outer wall of the feeding hopper 3. The motor 6 is fixedly mounted on the outer wall of the support plate 5. A rotating shaft 8 is rotatably mounted inside the feeding hopper 3 through a connecting plate 7. Both the rotating shaft 8 and the outer wall of the drive shaft 4 are fixedly mounted with bevel gears 9. The two bevel gears 9 mesh perpendicularly. Multiple stirring rods 11 are fixedly mounted on the outer wall of the rotating shaft 8 through the mounting mechanism. The mounting mechanism includes a mounting sleeve 10 fixedly mounted on the outer wall of the rotating shaft 8. Each stirring rod 11 is fixedly mounted on the outer wall of the mounting sleeve 10.

[0023] A first connecting block 12 and a second connecting block 13 are fixedly installed on the outer wall of the rotating shaft 8. A first scraper 15 is fixedly connected to both outer walls of the first connecting block 12 through a first connecting mechanism. The first connecting mechanism includes a first connecting rod 14 fixedly installed on the outer wall of the first connecting block 12. The end of the first connecting rod 14 is fixedly connected to the outer wall of the first scraper 15. A second scraper 17 is fixedly connected to both outer walls of the second connecting block 13 through a second connecting mechanism. The second connecting mechanism includes a second connecting rod 16 fixedly installed on the outer wall of the second connecting block 13. The end of the second connecting rod 16 is fixedly connected to the outer wall of the second scraper 17. An air pump 19 is fixedly installed on the upper surface of the feeding hopper 3 through a support frame 18. An air extraction hood 20 is fixedly installed on the outer wall of the inlet pipe of the air pump 19. A dust collector bag 21 is fixedly installed on the outer wall of the outlet pipe of the air pump 19.

[0024] When using this utility model, the rubber material is first poured into the feeding hopper 3. At this time, the rubber material can fall into the feeding channel 2 inside the feeding hopper 3. During this process, the motor 6 can drive the transmission shaft 4 to rotate. The transmission shaft 4 can drive the rotating shaft 8 to rotate through two vertically meshing bevel gears 9. The rotating shaft 8 can then drive multiple stirring rods 11 to rotate through the cooperation of the mounting sleeve 10. This allows the multiple stirring rods 11 to stir the rubber material inside the feeding hopper 3, thereby avoiding a large amount of rubber material accumulating inside the feeding hopper 3 and causing blockage, thus preventing it from affecting normal feeding.

[0025] Meanwhile, the rotating shaft 8 can drive the first connecting block 12 and the second connecting block 13 to rotate. The first connecting block 12 can drive the two first scrapers 15 to rotate through the two first connecting rods 14. The second connecting block 13 can drive the two second scrapers 17 to rotate through the cooperation of the two second connecting rods 16. At this time, the two first scrapers 15 and the two second scrapers 17 can scrape the inner wall of the feeding hopper 3, thereby preventing the rubber material from sticking to the inner wall of the feeding hopper 3 and being unable to be fed. When dust is generated during the mixing process, the air pump 19 can extract the dust in the air through the cooperation of the air extraction hood 20 and discharge it into the dust collector bag 21. The dust collector bag 21 can intercept and filter the dust, thereby preventing a large amount of dust from floating in the air and affecting the health of the operators.
