Description

Technical Field

[0001] This utility model relates to the field of plastic masterbatch production technology, and in particular to a plastic masterbatch feeding device. Background Technology

[0002] Filler masterbatch is a particle obtained by mixing various additives, fillers and a small amount of carrier resin during the plastic processing and molding process. It can be used in woven bags, hollow products, pipes, sheets, injection molded products and plastic fast food boxes, and can improve the performance of plastic products and reduce product costs.

[0003] In the existing technology, plastic masterbatch needs to be cleaned during the feeding process, and the cleaned plastic masterbatch needs to be dried. However, during the drying process, the plastic masterbatch is prone to sticking together due to a large amount of water, making it difficult to dry the sticking plastic masterbatch completely. Moreover, during the drying process, it is often necessary to wait for the previous batch of plastic masterbatch to be dried and fed before the next batch of plastic masterbatch can be dried and fed, making it difficult to continuously feed and dry the masterbatch. This results in a relatively slow drying and feeding efficiency. Utility Model Content

[0004] This utility model provides a plastic masterbatch feeding device, which helps to ensure the thorough drying of plastic masterbatch and improve drying efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A plastic masterbatch feeding device includes a feeding box and a feeding hopper, wherein the feeding hopper is connected to the upper left side of the feeding box;

[0007] Below the feed hopper is a rotating rod located inside the feeding box. Beating plates are fixed around the perimeter of the rotating rod. A ventilation screen is installed inside the feeding box. A feeding pipe is connected to the right end of the feeding box. The right end of the ventilation screen extends into the feeding pipe. A support block is fixed at the bottom of the feeding pipe. The upper end of the support block is hinged to the lower right side of the ventilation screen. A support plate located below the ventilation screen is fixed to the left wall inside the feeding box. A spring is connected between the support plate and the ventilation screen. An impact shaking component is installed on the lower left side of the ventilation screen.

[0008] A drying pipe is provided below the ventilation mesh plate, and several drying nozzles are connected to both the upper and lower parts of the drying pipe. A dryer is fixed on the right side of the feeding box, and a synchronous rotation drive assembly is provided on the left side of the drying pipe.

[0009] Furthermore, the impact vibration assembly includes an impact ball and a semi-circular impact block. Two impact balls are provided and are respectively fixed to the upper and lower parts of the drying tube. The semi-circular impact block is fixed to the lower end of the ventilation mesh plate. The impact ball and the semi-circular impact block correspond to each other.

[0010] Furthermore, the synchronous rotation drive assembly includes a motor, a drive gear, a rotating shaft, a driven gear, and two pulleys. The motor is fixed to the lower end of the support plate, and the drive gear is connected to the motor's power end.

[0011] Furthermore, the rotating shaft is fixed to the left end of the drying tube, the driven gear is fixedly sleeved around the drying tube, and the driven gear meshes with the driving gear.

[0012] Furthermore, the rotating shaft rotates through the left side of the feeding box, one of the pulleys is fixed to the left end of the rotating shaft, the rotating rod rotates through the left side of the feeding box, and the other pulley is fixed to the left end of the rotating rod. The two pulleys are connected by a belt.

[0013] Furthermore, the air outlet of the dryer is connected to an air outlet pipe that penetrates into the feeding box, and the right end of the drying pipe is rotatably connected to and communicates with the air outlet pipe.

[0014] Furthermore, a drain pipe is connected to the lower left end of the feeding box.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting up a tapping plate, it is beneficial to tap and disperse the plastic masterbatch that is stuck together in advance, so as to avoid the occurrence of a large number of plastic masterbatches sticking together, and effectively improve the thoroughness of subsequent drying.

[0017] 2. By continuously striking the semi-circular impact block with the impact ball, combined with the elastic force of the spring, the ventilation mesh plate shakes and tilts, which helps to shake and dry the plastic masterbatch, better prevents the plastic masterbatch from sticking together, and thus better improves the thoroughness of drying the plastic masterbatch.

[0018] 3. The plastic masterbatch is dried by multiple rotating drying nozzles, which effectively ensures the comprehensive drying of the plastic masterbatch. During the drying process, the plastic masterbatch will automatically slide down the inclined surface of the shaking and tilting ventilation mesh plate and exit the feeding pipe. Therefore, it is convenient to continuously add material to the feeding box for drying and to continuously feed material for drying, which effectively ensures the feeding efficiency.

Detailed Implementation

[0025] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0026] like Figure 1-3 As shown, this embodiment includes a feeding box 1 and a feeding hopper 2. The feeding hopper 2 is connected to the upper left side of the feeding box 1. A rotating rod 3 located inside the feeding box 1 is provided below the feeding hopper 2. Beating plates 4 are fixed around the periphery of the rotating rod 3. A ventilation mesh plate 5 is provided inside the feeding box 1. A feeding pipe 6 is connected to the right end of the feeding box 1. The right end of the ventilation mesh plate 5 extends into the feeding pipe 6. A support block 19 is fixed at the bottom of the feeding pipe 6. The upper end of the support block 19 is hinged to the lower right side of the ventilation mesh plate 5. A support plate 7 located below the ventilation mesh plate 5 is fixed to the left wall of the feeding box 1. A drying pipe 12 is provided below the ventilation mesh plate 5. A synchronous drying pipe 12 is provided on the left side of the drying pipe 12. The rotary drive assembly includes a motor 8, a drive gear 9, a rotating shaft 10, a driven gear 11, and two pulleys 15. The motor 8 is fixed to the lower end of the support plate 7. The drive gear 9 is connected to the power end of the motor 8. The rotating shaft 10 is fixed to the left end of the drying tube 12. The driven gear 11 is fixedly sleeved around the drying tube 12 and meshes with the drive gear 9. The rotating shaft 10 rotates through the left side of the feeding box 1. One pulley 15 is fixed to the left end of the rotating shaft 10. The rotating rod 3 rotates through the left side of the feeding box 1. The other pulley 15 is fixed to the left end of the rotating rod 3. The two pulleys 15 are connected by a belt.

[0027] The cleaned plastic masterbatch is added into the feeding box 1 through the feeding hopper 2. When the synchronous rotation drive component is working, the motor 8 drives the drive gear 9, driven gear 11, rotating shaft 10, pulley 15, rotating rod 3 and tapping plate 4 to rotate together. Therefore, the tapping plate 4 will tap the plastic masterbatch entering the feeding box 1, which helps to disperse the plastic masterbatch that is stuck together in advance, avoids the situation where a large amount of plastic masterbatch sticks together, and effectively improves the thoroughness of subsequent drying.

[0028] like Figure 1 ,2 As shown in Figure 4, in this embodiment, a spring 16 is connected between the support plate 7 and the ventilation mesh plate 5. An impact shaking component is provided on the lower left side of the ventilation mesh plate 5. The impact shaking component includes an impact ball 13 and a semi-circular impact block 14. Two impact balls 13 are provided and are respectively fixed to the upper and lower parts of the drying tube 12. The semi-circular impact block 14 is fixed to the lower end of the ventilation mesh plate 5. The impact ball 13 and the semi-circular impact block 14 correspond to each other.

[0029] The rotation of the rotating shaft 10 drives the drying tube 12 and the impact ball 13 to rotate together. The impact ball 13 will continuously impact the semi-circular impact block 14, thereby pushing the ventilation mesh plate 5 upward. The ventilation mesh plate 5 will stretch the spring 16. Since the lower right side of the ventilation mesh plate 5 is supported by the support block 19, and the support block 19 is hinged to the lower right side of the ventilation mesh plate 5, combined with the elastic force of the spring 16, the ventilation mesh plate 5 will move down and reset. Therefore, the ventilation mesh plate 5 will continuously shake and tilt around the support block 19 as the fulcrum, which is conducive to shaking and drying the plastic masterbatch. The plastic masterbatch that is stuck together will shake and disperse, which better prevents the plastic masterbatch from sticking together, thereby improving the thoroughness of drying the plastic masterbatch.

[0030] like Figure 1-2 As shown in this embodiment, the upper and lower parts of the drying pipe 12 are connected to several drying nozzles 20. A dryer 17 is fixed on the right side of the feeding box 1. The air outlet of the dryer 17 is connected to an air outlet pipe 18 that penetrates into the feeding box 1. The right end of the drying pipe 12 is rotatably connected to and communicates with the air outlet pipe 18. A drain pipe 21 is connected to the lower left end of the feeding box 1.

[0031] The dryer 17 delivers hot air to the exhaust pipe 18, drying pipe 12, and drying nozzle 20. The hot air is sprayed onto the plastic masterbatch on the ventilation mesh plate 5 through the drying nozzle 20, which facilitates the drying of the plastic masterbatch. Excess water leaks down through the ventilation mesh plate 5 to the bottom of the feeding box 1 and is finally discharged through the drain pipe 21. When the rotating shaft 10 rotates, it drives the drying pipe 12 and the drying nozzle 20 to rotate together. Therefore, the plastic masterbatch is dried by multiple rotating drying nozzles 20, which effectively ensures the comprehensive drying of the plastic masterbatch. During the drying process, the plastic masterbatch will automatically slide down the inclined surface of the shaking ventilation mesh plate 5 and exit the feeding pipe 6, which facilitates the continuous feeding and drying of the plastic masterbatch into the feeding box 1 and ensures the feeding efficiency.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, other implementations are also included. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
