DETAILED DESCRIPTION
[0031] The following is combined with Figure 1-3 This application is described in further detail.
[0032] Example:
[0033] See also Figure 1 and Figure 2 , an auxiliary feeding device for an internal mixer, comprising a lifting frame 19 installed on an internal mixer body 1. The internal mixer body 1 is provided with an operating table 2 and a feeding end 3 for a mixed material. A feeding hopper 4 is fixed to the top of the lifting frame 19, a feeding port is provided on the top surface of the feeding hopper 4, a discharging port is provided on the bottom surface of the feeding hopper 4, and a discharging pipe 5 is fixedly connected to the discharging port. A bracket 6 is also fixedly connected to the operating table 2 of the internal mixer body 1, and the bracket 6 is used to support the discharging pipe 5 so that the end of the discharging pipe 5 away from the feeding hopper 4 is aligned with the feeding end 3 of the internal mixer body 1.
[0034] When the rubber needs to be mixed and processed, the feed hopper 4 is first lifted by the lifting frame 19, and the discharge port of the feed hopper 4 is higher than the feed end 3 of the internal mixer body 1. At this time, the discharge pipe 5 is tilted toward the feed end 3 of the internal mixer body 1. Then, the mixed material is added to the feed port of the feed hopper 4. Under the action of the self-gravity of the mixed material, the mixed material passes through the discharge port and the discharge pipe 5 in sequence, and then falls into the feed end 3 of the internal mixer body 1.
[0035] For details, see Figure 1 The lifting frame 19 includes a frame tube 7 and a frame rod 8. The frame tube 7 is fixed on the operating table 2 and is vertically arranged. The frame rod 8 is slidably connected in the frame tube 7, and the top of the frame rod 8 extends above the frame tube 7. The top of the frame rod 8 is fixedly connected to the side wall of the feed hopper 4.
[0036] See also Figure 1 and Figure 2 In order to facilitate the fixing of the frame rod 8 in the frame tube 7 after lifting, the frame tube 7 is installed with a locking assembly, which includes an insertion rod 9. A lock cylinder 10 is fixed to the side wall of the frame tube 7, and the insertion rod 9 is slidably installed in the lock cylinder 10. One end of the insertion rod 9 passes through the lock cylinder 10 and the frame tube 7 in sequence and extends into the frame tube 7. The other end of the insertion rod 9 passes through the lock cylinder 10 and extends outside the side wall of the lock cylinder 10. The side wall of the frame rod 8 is penetrated by an insertion hole 11, and one end of the insertion rod 9 is plugged into the insertion hole 11.
[0037] See also Figure 2 In order to improve the stability of the insertion rod 9 inserted into the insertion hole 11, the lock cylinder 10 is installed with a first elastic member, which is a first spring 12. The first spring 12 is installed in the lock cylinder 10, and the first spring 12 is sleeved on the insertion rod 9. The side wall fixed ring of the insertion rod 9 is provided with a moving ring 13, and the moving ring 13 is slidably connected in the lock cylinder 10. One end of the first spring 12 is fixedly connected to the inner wall of the lock cylinder 10, and the other end of the first spring 12 is fixedly connected to the surface of the moving ring 13.
[0038] When the other end of the insertion rod 9 is pulled outward, the insertion rod 9 squeezes the first spring 12 through the moving ring 13, and the rack rod 8 is now freed from restriction and can be lifted and moved along the vertical direction of the rack tube 7. When the feed hopper 4 is lifted to the desired height, the insertion rod 9 is released, the first spring 12 releases its elastic force, and drives the insertion rod 9 to move toward the rack rod 8 through the moving ring 13, and the insertion rod 9 is now inserted into the insertion hole 11, and the rack rod 8 and the feed hopper 4 are fixed at the current height.
[0039] It is worth noting that see Figure 1 There are multiple sockets 11, and the multiple sockets 11 are distributed in a linear array along the vertical direction of the frame rod 8. Under the action of the multiple sockets 11, it is beneficial to adjust the fixed height of the feed hopper 4, thereby changing the inclination angle of the discharge pipe 5, and then adjusting the discharge rate.
[0040] See also Figure 1 and Figure 3 The side wall of the bracket 6 is penetrated with a sliding hole 14, the discharge pipe 5 is penetrated through the sliding hole 14, and the discharge pipe 5 is slidably connected to the sliding hole 14. A fixing ring 20 is installed in the bracket 6, the fixing ring 20 is slidably connected in the sliding hole 14, and the fixing ring 20 is fixedly sleeved on the side wall of the discharge pipe 5.
[0041] See also Figure 3 In order to cooperate with the movement of the fixing ring 20, a second elastic member is installed in the bracket 6, and the second elastic member is a second spring 15. The second spring 15 is installed in the sliding hole 14, one end of the second spring 15 is fixedly connected to the bottom surface of the fixing ring 20, and the other end of the second spring 15 is fixedly connected to the hole wall of the sliding hole 14.
[0042] When the fixing ring 20 is pressed downward, the fixing ring 20 moves downward and compresses the second spring 15. When the fixing ring 20 is released, the second spring 15 releases its elastic force and drives the fixing ring 20 to move upward, and the fixing ring 20 hits the hole wall of the sliding hole 14, thereby vibrating the discharge pipe 5. Under the action of the vibration force, the mixed material adhering to the inner wall of the discharge pipe 5 is shaken off.
[0043] See also Figure 3 In order to improve the convenience of driving the fixed ring 20 to move, the side wall of the fixed ring 20 is fixedly connected with a handle 16, and the fixed ring 20 is driven to move downward by the handle 16. At the same time, when the mixed material is normally replenished, in order to prevent the discharge pipe 5 from shaking and causing the mixed material to fall outside the feed end 3 of the internal mixer body 1, the side wall of the bracket 6 is fixedly connected with a positioning ear 17, and a latch 18 is inserted between the positioning ear 17 and the handle 16. Under the action of the latch 18, the fixed ring 20 is fixed at the current height position.
[0044] It is worth noting that, in the present embodiment, the discharge pipe 5 is a corrugated hose, which is conducive to changing the different inclination angles of the discharge pipe 5 through the corrugated hose.
[0045] Working principle of an auxiliary feeding device for internal mixer:
[0046] When it is necessary to load materials, first pull the other end of the plug rod 9 outwards, and the plug rod 9 squeezes the first spring 12 through the moving ring 13. At this time, the frame rod 8 is released from the restriction and can be lifted and moved along the vertical direction of the frame tube 7. When the feed hopper 4 is lifted to the required height, release the plug rod 9, the first spring 12 releases the elastic force, and drives the plug rod 9 to move toward the frame rod 8 through the moving ring 13. At this time, the plug rod 9 is inserted into the socket 11, the frame rod 8 and the feed hopper 4 are fixed at the current height, and the discharge port of the feed hopper 4 is higher than the feed end 3 of the internal mixer body 1. Then pour the mixture into the feed port of the feed hopper 4, and the mixture passes through the discharge port and the discharge pipe 5 in turn, and finally falls into the feed end 3 of the internal mixer body 1, completing the loading of the mixture.
[0047] When it is necessary to clean the mixed material adhering to the discharge pipe 5, the latch 18 is released, and the fixing ring 20 is pressed downward by the handle 16, so that the fixing ring 20 moves downward and squeezes the second spring 15. When the fixing ring 20 is released, the second spring 15 releases its elastic force and drives the fixing ring 20 to move upward, and the fixing ring 20 hits the hole wall of the sliding hole 14, thereby vibrating the discharge pipe 5. Under the action of the vibration force, the mixed material adhering to the inner wall of the discharge pipe 5 is shaken off.
[0048] In summary, the feed hopper 4 is used to make the mixed material fall to the feed end 3 of the internal mixer body 1 through the discharge pipe 5, avoiding the direct addition of the mixed material into the feed end 3 of the internal mixer body 1, thereby improving the safety and convenience of the mixed material feeding.
[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
