Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber processing machinery technology, specifically to an automated feeding open-type rubber mixing machine. Background Technology
[0002] Open-type rubber mixing mills were first used in production in 1826. They have a relatively simple structure and are still widely used today. During mixing, they mainly rely on two relatively rotating rollers to squeeze and shear the rubber compound. Through multiple kneading processes and the chemical reactions that accompany the kneading, the large molecular chains inside the rubber are broken, so that the various components in the formula are mixed evenly.
[0003] A patent with authorization announcement number "CN208100818U" discloses an open-type rubber mixing mill, including a base, rollers, a limiting device, and a receiving plate. A frame is fixed on both sides of the base, and a roller seat is provided on the opposite side of the frame. A front roller and a rear roller are arranged between the relatively fixed roller seats. Four support columns are fixed on the base, and a receiving plate is connected above the four support columns. A receiving tray is placed on the upper surface of the receiving plate. The setting of the receiving plate and receiving tray enables timely collection of residual material, avoiding waste and difficulty in cleaning caused by residual material falling and sticking to the base.
[0004] However, this device has the following shortcomings:
[0005] 1. During the rubber mixing process, various components need to be added to the rubber. However, the above-mentioned device cannot mix the rubber with the mixing components. It also requires manual addition of various materials. It cannot automatically feed materials, which reduces the ease of use of the device.
[0006] 2. Dust and impurities may easily get mixed into the raw materials of the rubber mixing mill during storage. The above-mentioned device cannot filter the rubber material when feeding it into the rubber mixing mill, which makes it easy for dust to mix into the rubber material and affect the quality of rubber mixing.

[0027] The top of the feeding hopper 5 is provided with a feeding cylinder 7 connected to the feeding hopper 5. The bottom side of the feeding cylinder 7 is provided with a guide pipe connected to the feeding hopper 5. The material conveyed in the feeding cylinder 7 can be guided into the feeding hopper 5 through the guide pipe. A spiral conveying rod 6 is sleeved on one side inside the feeding cylinder 7. A feeding hopper 12 is provided on one side of the top of the feeding cylinder 7. A protective shell 8 is provided on one side of the feeding cylinder 7. A dust collection trough 10 is opened at the bottom of the feeding cylinder 7. A collection box 11 is sleeved on the inner side of the dust collection trough 10. A filter screen 13 connected to the dust collection trough 10 is provided at the bottom inside the feeding cylinder 7.
[0028] The top of the inside of the feeding bin 5 is fitted with a rotating rod 9, and two sets of stirring rods 17 are provided on the outside of the rotating rod 9. The top of the inside of the protective shell 8 is fitted with a motor B16, and a reinforcing plate is provided on one side of the inside of the protective shell 8. The reinforcing plate is fitted on the outside of the output end of the protective shell 8, which can improve the rotational stability of the motor output end. The output end of the motor B16 and the top of the outside of the rotating rod 9 are fitted with a meshing transmission gear 15. The top of the rotating rod 9 and one side of the screw conveyor rod 6 are fitted with a meshing bevel gear 14. The bottom of the inside of the feeding bin 5 is fitted with a feeding assembly.
[0029] The feeding assembly includes a feeding hole 18, a rotating wheel 20, a turntable 21, a locking tooth 22, a ratchet groove 23, and a spring 24. The turntable 21 is located at the bottom inside the feeding bin 5. The top of the turntable 21 is equipped with an arc-shaped guide plate, which can guide the raw material to the feeding hole 18 for easy discharge into the feeding bin 5. The inner side of the turntable 21 is provided with a ratchet groove 23. The bottom of the rotating rod 9 extends to the inner side of the ratchet groove 23 and is provided with a rotating wheel 20. The top edge of the rotating wheel 20 is fitted with a locking tooth 22. One side of the locking tooth 22 is provided with a spring 24 connected to the rotating wheel 20. The top of the turntable 21 is provided with four sets of feeding holes 18 that cooperate with the feeding pipe 19. The automatic discharge of mixed raw materials in the feeding bin 5 can be controlled by controlling the reverse rotation of the motor B16, thus realizing automated feeding.
[0030] Example:
[0031] The bottom of the inner side of the mounting frame 2 is equipped with a material collection trough, and the two sides of the inner side of the material collection trough are equipped with guide inclined plates. The middle of the inner side of the material collection trough is equipped with a material collection box, which can collect the material residue generated during processing. During rubber refining, the fallen rubber material can roll into the material collection box under the guidance of the guide inclined plates. The material collection box can be removed later to refining and reuse the fallen rubber material, which can reduce the consumption of raw materials and improve the ease of cleaning the processing table.
[0032] Working principle: When the device is used for rubber mixing, the motor B16 can be started to run, and then the raw materials are added through the feed hopper 12. The material falls into the feed cylinder 7 through the feed hopper 12. The motor B16 drives the rotating rod 9 to rotate clockwise under the meshing of two sets of transmission gears 15. At this time, the rotating rod 9 drives the bevel gear 14. The meshing of the two sets of bevel gears 14 drives the screw conveyor 6 to rotate, thereby conveying the material in the feed cylinder 7. During the material conveying process, the dust and impurities in the material can be filtered through the filter screen 13. The filtered impurities can be collected in the collection box 11 for convenient subsequent centralized processing.
[0033] The material can be conveyed and enter the feeding bin 5 through the guide pipe. At this time, the rotating rod 9 can drive the two sets of stirring rods 17 to stir and mix the material, eliminating the need for staff to add rubber raw materials one by one.
[0034] When the rotating rod 9 rotates clockwise, it drives the rotating wheel 20 to rotate clockwise. At this time, the locking teeth 22 can rotate along the ratchet groove 23 and cannot engage with the ratchet groove 23. The four sets of feeding holes 18 are also misaligned with the feeding pipe 19, so that the material in the feeding bin 5 cannot be discharged. After the raw materials are mixed, the motor B16 can be controlled to reverse. At this time, the motor B16 can drive the rotating rod 9 to rotate counterclockwise. The rotating rod 9 can drive the rotating wheel 20 to rotate. At this time, the locking teeth 22 can engage with the ratchet groove 23 under the elastic force of the spring 24, so that the rotating wheel 20 can drive the turntable 21 to rotate. When the turntable 21 rotates, the feeding pipe 19 can be intermittently aligned with the feeding pipe 19, so that the mixed material is discharged for refining, realizing automated feeding.
