[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 1 , 2 As shown, this embodiment mainly discloses a feeding device for a rubber extruder, including an auger 1 and a oscillating vibrator 2. The auger 1 has a feeding hopper 11 at its feeding end. One end of the oscillating vibrator 2 is rotatably connected to the discharge end of the auger 1, and the other end of the oscillating vibrator 2 is rotatably connected to an interface flange 3 for connecting to the feed port of the rubber extruder. The auger 1 and the interface flange 3 are relatively fixed. Specifically, the auger 1 can be a dual-shaft auger 1 or a single-shaft auger 1 as in the prior art. The auger 1 is horizontally arranged, and its top end is provided with a cover. The cover has a feeding hole and a feeding hopper 11. The rubber material enters the auger 1 through the feeding hopper 11 for crushing and stirring, and is conveyed to the discharge end of the auger 1. Then it enters the oscillating vibrator 2 for gentle oscillation, which effectively reduces the retention and blockage of the rubber material, ensures the fluidity of the rubber during the extrusion process, achieves stable and efficient rubber feeding, and improves production efficiency.

[0024] Furthermore, in a specific implementation, the aforementioned oscillating oscillator 2 provided in this embodiment of the present invention includes an outer cylinder 21, and actuating plates 23 are respectively provided on the opposite outer walls of the outer cylinder 21. The actuating plates 23 on both sides are driven by motors to rotate and actuate cams 4. Specifically, the actuating plates 23 extend radially outward on the opposite outer walls of the outer cylinder 21, and the actuating plates 23 can be integrally formed with the outer cylinder 21 by welding. In this embodiment, the cams 4 driven by the motors on both sides act on the lower end of the actuating plates 23. Since the auger 1 and the interface flange 3 are opposite to each other... The outer cylinder 21, which is fixed in the middle, can only rotate. At the same time, the far resting ends of the two cams 4 are 180° apart, and the two cams 4 rotate synchronously to periodically move the actuating plate 23, forming a stable amplitude vibration. This enables the outer cylinder 21 to oscillate periodically. Applying vibration to a constant shear field makes the rubber feeding process a periodic vibration field, which can effectively shake the rubber block and enhance its mixing effect with other components. It changes the fluidity of the rubber material, makes the feeding uniform, improves the feeding quality, and avoids feeding blockage.

[0025] Example 2

[0026] like Figure 3 , 4As shown, in this embodiment, the oscillating oscillator 2 further includes an inner cylinder 22, which is rotatably sealed to the auger 1 and the interface flange 3. The outer wall of the inner cylinder 22 is connected to the inner wall of the outer cylinder 21 by a spring. Preferably, multiple springs are evenly distributed around the circumference, so that the oscillation between the inner cylinder 22 and the outer cylinder 21 has a certain lag, which increases the vibration frequency to a certain extent, improves the oscillation effect, and makes the rubber mixture more fully mixed.

[0027] Preferably, sealing buffer rings 5 ​​are provided between the inner cylinder 22 and the auger 1, and between the inner cylinder 22 and the interface flange 3. Specifically, the two ends of the inner cylinder 22 are respectively fitted onto the auger 1 and the interface flange 3. The sealing buffer rings 5 ​​are not only located between the mating surfaces of the inner cylinder 22 and the auger 1 and the interface flange 3, but also between the overlapping surfaces of the inner cylinder 22 and the auger 1 and the interface flange 3. On the one hand, by setting the sealing buffer rings 5, dynamic and static sealing is achieved, ensuring the sealing performance of the system during operation and preventing leakage and external pollution. On the other hand, vibration can be isolated within the vibration range of the oscillating oscillator 2, reducing or eliminating the transmission of vibration to other components and causing damage to other components.

[0028] Preferably, the inner walls of the auger 1, the inner cylinder 22, and the interface flange 3 are all coaxially and smoothly connected, which reduces the resistance to the flow of the adhesive, improves the fluidity of the adhesive, reduces the friction and wear between the auger 1 and the inner wall of the pipe, extends the service life of the equipment, and reduces maintenance costs.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
