[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] Example 1: Please refer to Figures 1 to 4 The present invention provides a technical solution: a feeding mechanism, the feeding mechanism comprising: a control device 1, a vortex blower 2 fixedly installed directly behind the control device 1, and a Roots blower 3 arranged beside the vortex blower 2;
[0023] A dust collection bin 4, a dust collection frame 6 installed inside the dust collection bin 4, a vacuum material cup 7 connected to one side of the dust collection bin 4, and an injection molding device 5 connected to the lower end of the vacuum material cup 7, an injection molding device, including the aforementioned feeding mechanism.
[0024] In use, the control device 1 can drive the vortex blower 2 or the Roots blower 3 to evacuate the vacuum cup 7, creating negative pressure inside the vacuum cup 7. For short-distance, low-pressure conveying applications, the vortex blower 2 can be started; conversely, for conveying applications, the Roots blower 3 can be started. The dust collector 4, located between the vacuum cup 7 and the blower, filters the air during evacuation, preventing impurities from entering the blower. Long-term accumulation of impurities can cause wear or blockage of the blower blades, affecting its overall lifespan. This prevents impurities from damaging the blower.
[0025] Example 2: Based on Example 1, a dust collection bin 4 is provided to prevent impurities from entering the blower. The dust collection bin 4 has a funnel-shaped structure. A connection hole is opened on the outer wall of the dust collection bin 4 away from the Roots blower 3. A first connecting pipe 15 is fixedly installed in the connection hole. The side of the dust collection bin 4 near the Roots blower 3 is connected to the Roots blower 3 and the vortex blower 2 by a pipeline. A threaded connection hole is opened at the bottom of the dust collection bin 4. A collection bottle 19 is screwed into the threaded connection hole. When the vacuum cup 7 is being evacuated, the vortex blower 2 or the Roots blower 3 will pass through the dust collection bin 4 and act on the vacuum cup 7. The dust collection frame 6 inside the dust collection bin 4 is connected to the vacuum cup 7 through the first connecting pipe 15. During the evacuation process, the gas will be filtered by the dust collection frame 6 and then pass through the vortex blower 2 or the Roots blower 3, thereby preventing impurities from accumulating in the blower blades and causing blockage, which would damage the blower.
[0026] One end of the first connecting pipe 15 is connected to the vacuum cup 7, and the other end of the first connecting pipe 15 is fixedly installed with a second connecting pipe 16. The second connecting pipe 16 is fixedly installed on the side wall surface of the dust collector frame 6. A cleaning hole is opened on the side wall surface of the dust collector frame 6, and a cleaning pipe 17 is fixedly installed in the cleaning hole. A pulse blower 18 is fixedly installed at one end of the cleaning pipe 17. The pulse blower 18 is fixedly installed on the outer side of the dust collector 4. After multiple dust removals, a lot of dust will accumulate in the dust collector frame 6. At this time, the pulse blower 18 can be driven to clean the dust collector frame 6. The cleaned dust will be collected into the collection bottle 19 to avoid clogging of the dust collector frame 6 and affecting the dust removal effect.
[0027] Example 3: Based on Example 2, a control device 1 is provided to enable the feeding mechanism to transport materials in an energy-efficient manner. The control device 1 is fixedly installed on the surface of the support plate 8. The control device 1 is electrically connected to the vortex blower 2 and the Roots blower 3. The vortex blower 2 is fixedly installed on the surface of the first mounting plate 9, which is fixedly installed on the surface of the support plate 8. The side of the vortex blower 2 is connected to the dust collection bin 4 via a pipe. A control knob 10 is provided above the vortex blower 2. The Roots blower 3 is fixedly installed on the surface of the second mounting plate 11. Mounting plates are provided on one end and two edges of the second mounting plate 11. Mounting holes are opened on the surface of the mounting plates. A protective frame 12 is attached to the outer wall of the mounting plates. The protective frame 12 is located directly in front of the Roots blower 3. Holes are opened at the bottom of both sides of the protective frame 12, and mounting screws 13 are installed in the holes. The connecting end of the mounting screw 13 passes through the mounting plate, and a mounting nut is screwed onto the connecting end of the mounting screw 13. A silencer 14 is fixedly installed on one side of the Roots blower 3. The outer wall of the Roots blower 3 is connected to the dust collection bucket 4 by a pipeline. When feeding materials, the vortex blower 2 and the Roots blower 3 can be controlled according to the conveying requirements. When the conveying distance is short and the air pressure is low, the vortex blower 2 can be driven for conveying. When the conveying distance is long and the air pressure is high, the Roots blower 3 can be driven for conveying. The Roots blower 3 and the vortex blower 2 work together to reduce the energy consumption of conveying while efficiently conveying materials.
[0028] Working principle: In actual use, the control device 1 can drive the vortex blower 2 or the Roots blower 3 to evacuate the vacuum cup 7, creating negative pressure inside the vacuum cup 7. In short-distance, low-pressure conveying applications, the vortex blower 2 can be started; in the opposite case, the Roots blower 3 can be started. The dust collector 4, located between the vacuum cup 7 and the blower, can filter the air during evacuation, thus preventing impurities from entering the blower. Over time, these impurities can cause wear or blockage of the blower blades, affecting the overall lifespan. This avoids the problem of impurities entering the blower and damaging it.
