Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] Please see Figures 1 to 5 This utility model provides a technical solution: a raw material conveying device for manufacturing hardware products, including a feeding hopper 1, a screw feeder 7, an electric heating element 2 and a temperature controller 3. The inner wall of the feeding hopper 1 is provided with a cavity for installing the electric heating element 2. The electric heating element 2 is connected to the temperature controller 3. The temperature controller 3 is fixedly installed on the side of the support rod 4. The support rod 4 is fixedly installed on the bottom of the upper edge of the feeding hopper 1.

[0034] A base 5 is provided below the feed hopper 1. The feed hopper 1 is connected to the feed end of the screw feeder 7 through a conveying pipe 6 on the side. The screw feeder 7 is fixed to the upper end of the base 5 through a bracket 8. The upper end of the screw feeder 7 is connected to the feeding pipe 9. A driven gear ring 10 for driving the auger feeding component inside the screw feeder 7 is provided at the bottom of the screw feeder 7. The driven gear ring 10 is connected to the drive gear 12 through a gear chain 11.

[0035] The upper end of the base 5 is fixed to the chassis by a triangular fixing bracket 13. Inside the chassis, there is a drive motor 14. The output shaft of the drive motor 14 passes through the top of the chassis and is fixed to the drive gear 12. Considering the drawbacks of the feeding machine during use, the feeding hopper 1 is open. When liquid or moisture enters the hopper and small droplets are generated, it is easy for plastic particles to stick together, that is, the plastic particles stick to the inner wall of the hopper, thus affecting the feeding. This utility model uses an electric heating element 2 set inside the wall of the feeding hopper 1 in conjunction with a temperature controller 3 to heat the wall of the feeding hopper 1. After the wall is heated, the liquid droplets or water vapor attached to the inner wall of the feeding hopper 1 will be heated, thereby avoiding the water vapor causing the plastic particles to stick to the inner wall of the feeding hopper 1 and affecting the feeding.

[0036] The upper end of the base 5 is rectangularly fixed with four sleeve rods 15. An electric telescopic column 16 is fixed inside each sleeve rod 15. The telescopic end of the electric telescopic column 16 passes through the upper end of the sleeve rod 15 and is fixed to the bottom of the support rod 4. Self-locking casters 17 are installed at the four corners of the bottom of the base 5. The electric telescopic column 16 is used to adjust the height of the support rod 4. The above structure allows the user to adjust the height of the feed hopper 1 as needed, thus facilitating the workers to add materials.

[0037] The upper end of the feed hopper 1 is equipped with a protective cover ring 18. An intercepting net 19 is installed on the inner wall of the protective cover ring 18. The mesh size of the intercepting net 19 is smaller than the outer size of the plastic granules being fed. A negative pressure chamber for installing the intercepting net 19 is opened on the inner wall of the protective cover ring 18. A negative pressure pipe 23 is connected inside the negative pressure chamber and extends to the outside of the protective cover ring 18. Considering that there is dust on the surface of the stored plastic granules, in order to prevent dust from being fed into the smelting equipment, the dust on the surface of the plastic granules is treated by negative pressure, that is, the dust is adsorbed by negative pressure. In order to prevent the plastic granules from being accidentally sucked in, the intercepting net 19 is designed to intercept the plastic granules. That is, the size of the plastic granules is larger than the mesh size of the intercepting net 19.

[0038] The negative pressure pipe 23 extends through the side of the placement box 21. The placement box 21 is fixedly installed on the side of one of the support rods 4. The interior of the placement box 21 is equipped with a dustproof bag 22. The dustproof bag 22 serves to store the dust in the negative pressure air. The air will be discharged by a small negative pressure pump 26, while the dust will remain in the dustproof bag 22.

[0039] The upper end of the dust bag 22 is connected to the negative pressure pipe 23 through the pipe clamp 24, and the lower end of the dust bag 22 is fixed to the connecting pipe 25 through the pipe clamp 24. The bottom of the connecting rod passes through the placement box and is connected to the negative pressure end of the small negative pressure pump 26. The small negative pressure pump 26 is fixed to the bottom of the placement box 21. By using the pipe clamp 24 to fix the dust bag 22, it is convenient for workers to replace the dust bag 22 later.

[0040] Among them, the side of the sleeve rod 15 is provided with a guide sleeve 28 for the guide rod 27 to pass through. The top of the guide rod 27 is fixed to the support rod 4 by a limiting block 29. A dustproof bellows cover 30 is provided between the sleeve rod 15 and the support rod 4. The dustproof bellows cover 30 is sleeved on the outside of the electric telescopic column 16. By setting the dustproof bellows cover 30, the telescopic end of the electric telescopic column 16 is protected from dust.

[0041] The base 5 has a clamping block 32 fixedly installed on one side for hinged T-shaped rod 31. A grip 33 is movably connected to the upper end of T-shaped rod 31. The top of the grip 33 is provided with a handle. The grip 33 is fixed by a positioning bolt 34 at the front end of T-shaped rod 31. The grip 33 facilitates the user to move the base 5.

[0042] The feed hopper 1 has drive boxes 35 symmetrically fixed on both sides inside. Inside the drive box 35 is a backup power module 36. A remote control module 37 is provided on one side of the backup power module 36. Multiple base blocks 38 are fixedly installed on the top of the drive box 35. The upper end of each base block 38 is connected to the vibrating rod 40 through a spring 39. Each vibrating rod 40 has a cavity for placing the vibrating motor 41. Each spring 39 is covered with a dustproof telescopic sleeve 20. The two ends of each dustproof telescopic sleeve 20 are fixed to the base block 38 and the vibrating rod 40, respectively. By setting the vibrating rod 40, the plastic particles inside the feed hopper 1 are vibrated and loosened, thereby preventing the plastic particles from clumping. When the vibrating motor 41 works, the vibrating rod 40 connected by the spring 39 vibrates, and the vibrating rod 40 loosens the plastic particles in the feed hopper 1.
