Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing equipment, in particular to a raw material input device for rubber mixing. Background Art

[0002] Rubber is a polymer material with elasticity and flexibility, widely used in various industries and daily life. When processing rubber, carbon black oil needs to be transported to the internal mixer for mixing. Currently, when transporting carbon black oil, it is necessary to use raw material input equipment for transportation;

[0003] For example, the Figure 4 , shows a raw material input device for rubber mixing in the prior art, including a material guide pipe, a flange piece 1 is fixedly installed at the bottom of the material guide pipe, a solenoid valve connected to the material guide pipe is fixedly installed at the bottom of the flange piece 1 by screws, and a conical material discharge pipe is fixedly installed at the bottom of the solenoid valve by multiple screws. When the raw material input device of the prior art is used to transport carbon black oil, the bottom end of the discharge pipe is extended into the feed inlet of the internal mixer, the solenoid valve is controlled to open, and the carbon black oil is transported into the material guide pipe, and then it can be transported to the internal mixer for processing through the discharge pipe. After the carbon black oil is transported according to the ratio, the solenoid valve is controlled to close to limit the continuous transportation of the carbon black oil, which is convenient for control. However, in actual use, the following defects still exist:

[0004] Since the discharge pipe is tapered and gradually becomes smaller along the bottom discharge port, the carbon black oil is easily attached to the inner wall of the discharge pipe during the transportation of the carbon black oil. After long-term use, it is easy to cause the inside of the discharge pipe to be blocked, reducing the carbon black oil transportation efficiency, thereby requiring workers to disassemble and clean the discharge pipe. When the raw material input equipment of the above-mentioned prior art disassembles the discharge pipe, it is necessary to remove multiple screws used to fix the solenoid valve and the discharge pipe one by one, which is more troublesome and reduces the disassembly efficiency. At the same time, it is inconvenient to install and fix the discharge pipe, thereby affecting production efficiency.

[0005] Therefore, the present application proposes a raw material input device for rubber mixing. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a raw material input device for rubber mixing, which solves the problems mentioned in the background art.

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] The second flange is provided with a sealing member for acting on the electromagnetic valve. When the first flange and the second flange are positioned by the positioning mechanism, the sealing member fits in with the electromagnetic valve.

[0012] Furthermore: the sealing member includes a sealing gasket fixedly mounted on the top of the second flange. When the first flange and the second flange are positioned by the positioning mechanism, a conflict is formed between the sealing gasket and the solenoid valve.

[0013] Furthermore: the feed pipe includes a first pipe body, a second pipe body, a corrugated hose, a fixing block, a connecting block, a connecting plate, a rotating shaft and an adjusting member;

[0014] The second flange is fixedly installed on the top of the first tube body, and the bottom of the first tube body is connected to the second tube body through a corrugated hose. The second tube body is conical, and the outer wall of the first tube body is symmetrically fixed with a fixed block, and the outer wall of the second tube body is symmetrically fixed with a connecting block. A connecting plate is rotatably installed on the fixed block through a rotating shaft, and the other ends of the two connecting plates are respectively fixedly connected to the two connecting blocks. One of the fixed blocks is equipped with an adjusting member that acts on the rotating shaft, which is used to rotate or stop the rotating shaft on the fixed block.

[0015] Furthermore: the adjusting member includes a worm wheel coaxially fixed to the rotating shaft, and a worm engaged with the worm wheel is rotatably mounted on the fixed block.

[0016] Further: the connecting plate includes a connecting shell, a plate body and a driving member, the connecting shell is fixedly installed on the connecting block, one end of the connecting shell movably passes through the plate body, the plate body is rotatably connected to the fixed block through a rotating shaft, and a driving member connected to the plate body is installed on the connecting shell, which is used to make the plate body slide or stop sliding along the connecting shell.

[0017] Furthermore: the driving member includes a driving rod rotatably mounted on the connecting shell, one end of the driving rod extends into the connecting shell and is threadedly connected to the plate body.

[0018] The utility model provides a raw material input device for rubber mixing. Compared with the prior art, it has the following beneficial effects:

[0019] 1. When the discharge pipe needs to be disassembled and cleaned, the positioning mechanism between flange piece 1 and flange piece 2 can be removed to disassemble the discharge pipe. This replaces the installation method of fixing the solenoid valve and the discharge pipe with multiple screws, making it easier to disassemble the discharge pipe and improving the disassembly efficiency. At the same time, it is easier to install and fix the discharge pipe, which is beneficial to the subsequent transportation of carbon black oil by the equipment, thereby improving production efficiency.

[0020] 2. By providing a seal, when the positioning mechanism positions the flange piece 1 and the flange piece 2, the seal fits against the solenoid valve, thereby increasing the fit between the flange piece 2 and the solenoid valve, thereby increasing the sealing between the flange piece 2 and the solenoid valve;

[0021] 3. During use, the rotating shaft can be rotated on the fixed block through the adjusting piece, so that the second tube body can be rotated around the rotating shaft through the connecting plate, and the angle between the second tube body and the first tube body can be adjusted.

During this period, when the angle between the second tube body and the first tube body is adjusted, the corrugated hose itself is deformed, which does not affect the normal use of the discharge pipe.

[0029] Example 1

[0030] In order to solve the technical problems in the background technology, a raw material input device for rubber mixing is provided as follows:

It also includes a feed pipe 2, which is detachably installed at the bottom of the solenoid valve 12, and a flange 2 3 is fixedly installed on the top of the feed pipe 2. A positioning mechanism 4 is symmetrically installed on the outer wall of the feed pipe 2 and located on the outer side of the flange 2 3.

When the positioning mechanism 4 is used to form the positioning between the flange 11 and the flange 2 3, the seal 5 fits against the solenoid valve 12.

[0032] During installation, the positioning mechanism 4 is used to position the flange 11 and the flange 2 3, and the bottom end of the feed pipe 2 is extended to the feed port of the internal mixer. When the carbon black oil is transported, the solenoid valve 12 is controlled to open and the carbon black oil is transported to the guide pipe 1, and then it can be transported to the internal mixer through the feed pipe 2 for processing. After the carbon black oil is transported according to the ratio, the solenoid valve 12 is controlled to close to limit the continuous transportation of the carbon black oil. When the feed pipe 2 needs to be disassembled and cleaned, the positioning mechanism 4 between the flange 11 and the flange 2 3 is canceled, and the feed pipe 2 can be disassembled and cleaned. The disassembly replaces the installation method of fixing the solenoid valve 12 and the discharge pipe 2 with multiple screws, which facilitates the disassembly of the discharge pipe 2 and improves the disassembly efficiency. At the same time, it is convenient for the installation and fixation of the discharge pipe 2, which is beneficial to the subsequent transportation of carbon black oil by the equipment, thereby improving production efficiency; by setting the seal 5, when the positioning mechanism 4 positions the flange 11 and the flange 2 3, the seal 5 and the solenoid valve 12 are in contact with each other, thereby increasing the fit between the flange 2 3 and the solenoid valve 12, thereby increasing the sealing between the flange 2 3 and the solenoid valve 12.

Specifically, it should be noted that the longitudinal section of the positioning rod 42 is L-shaped, one end of the positioning rod 42 in the vertical direction is fixedly connected to the slider 44, and one end in the horizontal direction can conflict with the flange 11, and an adjusting rod 43 threadedly connected to the slider 44 is rotatably installed on the positioning block 41. When in use, when positioning between the flange 11 and the flange 2 3, the discharge tube 2 is positioned in the electric On one side of the magnetic valve 12, and make the seal 5 on the top of the flange piece 2 3 flush with the bottom of the electromagnetic valve 12, and translate the discharge pipe 2 so that it is located directly below the electromagnetic valve 12 and is connected to the electromagnetic valve 12. At this time, the vertical ends of the two positioning rods 42 are respectively located on both sides of the flange piece 11, and the horizontal movement of the two positioning rods 42 is located above the flange piece 11. Rotate the two adjusting rods 43 respectively to make the two sliders 44 move along the two positioning blocks 41 away from the electromagnetic valve 12, which can drive the two positioning rods 42 to move respectively, so that the horizontal ends of the two positioning rods 42 are in conflict with the flange piece 11, so that the flange piece 11 and the flange piece 2 3 can be positioned, and the operation is simple.

[0036] In this embodiment, the sealing member 5 includes a sealing gasket 51 fixedly mounted on the top of the flange piece 2 3. The sealing gasket 51 is made of a rubber gasket. When the positioning mechanism 4 is used to form a positioning between the flange piece 11 and the flange piece 2 3, the sealing gasket 51 and the solenoid valve 12 are in conflict. When in use, one end of the two positioning rods 42 in the horizontal direction is in conflict with the flange piece 11. When the flange piece 11 and the flange piece 2 3 are positioned, the sealing gasket 51 and the solenoid valve 12 are in conflict, thereby increasing the fit between the flange piece 2 3 and the solenoid valve 12.

[0037] In this embodiment, the feeding pipe 2 includes a first tube body 21, a second tube body 22, a corrugated hose 23, a fixed block 24, a connecting block 25, a connecting plate 26, a rotating shaft 27 and an adjusting member 28; the flange 23 is fixedly installed on the top of the first tube body 21, and the bottom of the first tube body 21 is connected to the second tube body 22 through the corrugated hose 23. The second tube body 22 is conical, and the outer wall of the first tube body 21 is symmetrically fixed with a fixed block 24, and the outer wall of the second tube body 22 is symmetrically fixed with a connecting block 25. A connecting plate 26 is rotatably installed on the fixed block 24 through a rotating shaft 27. The connecting plate 26 is fixedly connected to the rotating shaft 27. The other ends of the two connecting plates 26 are respectively fixedly connected to the two connecting blocks 25. One of the fixed blocks 24 is installed with a connecting plate that acts on the rotating shaft 27. The adjusting member 28 is used to rotate or stop the rotating shaft 27 on the fixed block 24. When in use, the rotating shaft 27 can be rotated on the fixed block 24 through the adjusting member 28, so that the second tube body 22 is rotated around the rotating shaft 27 through the connecting plate 26, and the angle between the second tube body 22 and the first tube body 21 is adjusted. After the installation of the internal mixer is completed, when the discharge pipe 2 is installed, it is convenient to adjust the angle between the second tube body 22 and the first tube body 21 according to the position of the feed port of the internal mixer, so that the second tube body 22 is facing the feed port of the internal mixer, thereby improving the installation portability of the device. During this period, when the angle between the second tube body 22 and the first tube body 21 is adjusted, the corrugated hose 23 itself is deformed, which does not affect the normal use of the discharge pipe 2.

[0038] Example 3

When in use, the rotating shaft 27 can be driven to rotate on the fixed block 24 by rotating the worm 282 through the worm wheel 281. The operation is simple. Since the meshing of the worm wheel 281 and the worm 282 is self-locking, the worm wheel 281 will not rotate when the worm 282 is not rotated, thereby fixing the position of the rotating shaft 27 for easy use.

[0041] In this embodiment, the connecting plate 26 includes a connecting shell 261, a plate body 262 and a driving member 263. The connecting shell 261 is fixedly installed on the connecting block 25. One end of the connecting shell 261 is movably penetrated by the plate body 262. The plate body 262 is rotatably connected to the fixed block 24 through the rotating shaft 27. The driving member 263 connected to the plate body 262 is installed on the connecting shell 261, which is used to make the plate body 262 slide or stop sliding along the connecting shell 261. When in use, after the internal mixer is installed, when the feeding pipe 2 is installed, according to At the feed port of the internal mixer, the angle between the second tube body 22 and the first tube body 21 is adjusted so that the second tube body 22 is facing the feed port of the internal mixer. Then, the plate body 262 is slid along the connecting shell 261 by the driving member 263 to displace the second tube body 22 away from the first tube body 21, so that the end of the second tube body 22 can be extended to the feed port of the internal mixer, thereby increasing applicability. During this period, when the angle between the second tube body 22 and the first tube body 21 is adjusted, the corrugated hose 23 itself is deformed, which does not affect the normal use of the discharge pipe 2.

[0042] In this embodiment, the driving member 263 includes a driving rod 2631 rotatably mounted on the connecting shell 261, one end of the driving rod 2631 extends into the connecting shell 261 and is threadedly connected to the plate body 262. When in use, the driving rod 2631 can be rotated to make the plate body 262 slide along the connecting shell 261. The operation is simple. Since the threaded connection between the driving rod 2631 and the plate body 262 is self-locking, the position of the plate body 262 can be fixed without rotating the driving rod 2631, which is convenient for use.
