[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1:

[0039] See also Figures 1 to 5 This embodiment provides a technical solution: a feeding device for preparing diaminodiphenyl ether, including: a base 1, a rotating rod 2, a conveyor belt assembly 3, a charging hopper 4, a driving component and a cleaning unit.

[0040] More specifically, in this embodiment: in actual use, the required raw materials for the preparation of diaminodiphenyl ether are put into the charging hopper 4, and then the conveyor belt assembly 3 is operated by the control panel to realize the transmission of the raw materials, so that the raw materials can enter the interior of the reaction container. When the height of the conveyor belt assembly 3 needs to be adjusted, the conveyor belt assembly 3 is driven by the operation of the driving component to adjust the elevation angle, and at the same time, the cleaning unit is linked to be deflected, and the cleaning unit is moved horizontally, so that the cleaning unit can be directly opposite to the corresponding charging hopper 4, and then the cleaning unit can perform jet cleaning on the charging hopper 4, and when facing directly, the occurrence of cleaning dead angles can be reduced.

[0041] It is worth noting that this embodiment also includes: an operating mechanism and a transmission mechanism.

[0042] More specifically, in this embodiment: through the operation of the conveyor belt assembly 3, under the action of the operating mechanism, the stable transmission of power is guaranteed without affecting the adjustment of the elevation angle of the conveyor belt assembly 3, and under the action of the transmission mechanism, the operation of the conveyor belt assembly 3 can be stored with energy. When the conveyor belt assembly 3 stops intermittently to unload materials, the energy can be released immediately, so that the cleaning gas is flushed into the cleaning unit, and the cleaning unit cleans the loading hopper 4 after use to ensure the cleanliness of the loading hopper 4.

[0043] Example 2:

[0044] Based on the above embodiment:

[0045] See also Figure 1 、 Figure 2 and Figure 3 The driving component in the first embodiment is disclosed as follows. The driving component includes:

[0046] Motor 15, the outer shell of motor 15 is fixedly connected to the back side of the fixed frame, the rotating part of motor 15 is fixedly connected to the driving wheel 10, the rotating rod 2 is connected to the driving wheel 10 through a pulley transmission mechanism 16, an adjusting wheel 7 is provided inside the base 1, the upper surface of the base 1 is slidably connected to the moving seat 8, the upper surface of the moving seat 8 is connected to the output wheel 9 through the shaft body for fixed axis rotation, the adjusting wheel 17, the driving wheel 10 and the output wheel 9 are connected through a pulley transmission mechanism 2 11, the outer surface of the adjusting wheel 7 is connected to the telescopic part 12 for fixed axis rotation, the telescopic part 12 is fixedly connected to the inner wall of the base 1, the outer shell of the telescopic part 12 and the opposite side of the inner wall of the base 1 are jointly fixedly connected to a spring 1, and the outer surface of the shaft body is fixedly connected to a shell 13.

[0047] More specifically, in this embodiment: through the operation of the rotating part of the motor 15, the driving wheel 10 is driven to rotate, and under the action of the pulley transmission mechanism 2 11, the rotating rod 1 2 and the conveyor belt assembly 3 are deflected synchronously, thereby achieving the purpose of adjusting the elevation angle of the conveyor belt assembly 3, and then under the connection of the pulley transmission mechanism 2 11, the output wheel 9 is driven to rotate, so that the shaft and the shell 13 are rotated synchronously, and the rotation direction is the same as that of the conveyor belt assembly 3, and then when the conveyor belt assembly 3 is deflected counterclockwise, the shell 13 is deflected counterclockwise, so that the shell 13 can always be aligned with the conveyor belt assembly 3 to a certain extent, to ensure that the gas ejected from the shell 13 can be aligned with the charging hopper 4 to avoid cleaning errors when the deviation angle is large. Among them, due to the adjustment of the elevation angle, the power transmission of the existing structure may be interrupted, so through the connection of the adjusting wheel 1 7, under its elastic and retractable nature, the output The belt of the conveyor assembly 3 can be adjusted in elongation to balance the distance difference caused by the elevation adjustment to ensure power transmission. This method has a high automation effect and does not require step-by-step adjustment. When the elevation angle of the conveyor belt assembly 3 is adjusted, the deflection angle of the shell 13 can be deflected synchronously to ensure the subsequent cleaning effect. The elevation angle of the conveyor belt assembly 3 is adjusted because the existing feeding device for the preparation of diaminodiphenyl ether usually needs to place different types of raw materials in the charging hopper 4 for conveying and feeding when feeding raw materials. However, the specifications of the actual stirring reaction container are not constant, so it may be necessary to adjust the angle of the feeding device, that is, the elevation angle. Therefore, the present invention can adjust the elevation angle of the conveyor belt assembly 3 according to actual needs, so that one end of the conveyor belt assembly 3 can finally rely on and dock at the position where docking is required, so as to meet the docking needs of most devices of different models and specifications on the market, thereby greatly improving the adjustability and intelligence of the device.

[0048] It is worth noting that in this embodiment: the outer surface of the connecting frame 35 is fixedly connected to the upper surface of the base 1, the side of the connecting frame 35 is fixedly connected to the motor 2 36, the rotating part of the motor 2 36 is fixedly connected to the screw 37, the threaded part of the screw 37 is threadedly connected to the moving part 38, the lower surface of the moving part 38 slides with the upper surface of the base 1, and the end of the shaft is fixedly rotatably connected to the outer surface of the moving part 38.

[0049] More specifically, in this embodiment: through the rotation of motor 2 36, the screw 37 will be driven to rotate, and under the thread transmission and sliding restriction, the movable member 38 will move laterally, thereby causing the shell 13 to move synchronously. The actual movement amount is based on the distance detected by the sensor and the control of the control board. After the offset, the movable member 38 is tilted to face the charging hopper 4 after the elevation adjustment, so as to avoid a large error in the alignment and the appearance of a cleaning injection dead angle, so as to ensure the cleanliness of the charging hopper 4 itself.

[0050] Example 3:

[0051] Based on the above embodiment:

[0052] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The cleaning unit in the first embodiment is disclosed as follows. The cleaning unit includes:

[0053] The outer shell of the shell 13 is fixedly connected to a nozzle 14 , a sensor 39 is installed on the side of the shell 13 facing the conveyor belt assembly 3 , and a hose 15 is fixedly connected to the side of the shell 13 .

[0054] More specifically, in this embodiment, since the elevation adjustment of the conveyor belt assembly 3 and the deflection of the housing 13 are performed synchronously, the housing 13 can be aligned with the lower side of the conveyor belt assembly 3 to a greater extent under certain conditions. Since the housing 13 also deflects when the elevation angle of the conveyor belt assembly 3 changes, the displacement changes, so that the loading hopper 4 may be perpendicular to the conveyor belt assembly 3, but not directly facing it by a certain distance. Therefore, the sensor 39 can automatically detect the situation, thereby operating the motor 2 36, thereby changing the lateral movement of the housing 13, so that the nozzle 14 always faces the corresponding loading hopper 4.

[0055] Specific: such as Figure 1 As shown, when the conveyor belt assembly 3 is adjusted in elevation counterclockwise, the shell 13 is also synchronously deflected counterclockwise, so the corresponding loading hopper 4 will be in a rightward position in the horizontal direction at this time. Therefore, it is necessary to move the shell 13 to the right for alignment to complete the adjustment of the elevation angle and the adjustment of the structure.

[0056] Example 4:

[0057] Based on the above embodiment:

[0058] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The operating mechanism in the first embodiment is disclosed as follows. The operating mechanism includes:

[0059] An adjusting wheel 16 is provided. A rotating shaft 17 is connected to the inner wall of the base 1 for fixed-axis rotation. A driven wheel 18 is fixedly connected to the outer surface of the rotating shaft 17. The rotating shaft of the conveyor belt assembly 3 is fixedly connected to a wheel body 19. The wheel body 19, the driven wheel 18 and the adjusting wheel 16 are connected in transmission through a pulley transmission mechanism 20. A telescopic shell 21 is fixedly connected to the upper surface of the base 1. A spring 2 is fixedly connected to the interior of the telescopic shell 21. The telescopic portion of the telescopic shell 21 is connected to the adjusting wheel 16 for fixed-axis rotation through a connecting shaft.

[0060] More specifically, in this embodiment: through the operation of the conveyor belt assembly 3, its rotating shaft and wheel body 19 will be driven to rotate continuously in the forward direction, thereby driving the driven wheel 18 to rotate under the action of the pulley transmission mechanism three 20, wherein the belt portion in the pulley transmission mechanism three 20 has a triangular property, so when the elevation angle of the conveyor belt assembly 3 itself is adjusted, the elastic telescopic shell 21 can always tighten the belt, and the seed belt can adapt to the distance generated when the elevation angle of the conveyor belt assembly 3 changes, thereby maintaining the power transmission of the conveyor belt assembly 3 toward the rotating shaft 17 without affecting the elevation angle adjustment of the conveyor belt assembly 3, so it is more practical and intelligent.

[0061] Embodiment 5:

[0062] Based on the above embodiment:

[0063] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The transmission mechanism in the first embodiment is disclosed as follows. The transmission mechanism includes:

[0064] Friction wheel 1 22, the center portion of friction wheel 1 22 is fixedly connected to the outer surface of the rotating shaft 17, a stabilizing rod 23 is fixedly connected to the inner wall of the base 1 for rotation, a friction wheel 2 24 is fixedly connected to the outer surface of the stabilizing rod 23, and a connecting friction wheel 25 is provided between friction wheel 2 24 and friction wheel 1 22;

[0065] One end of the rotating shaft 26 is fixedly connected to the center of the friction wheel 25, and the other end of the rotating shaft 26 is fixedly connected to the bracket 27. The lower end of the bracket 27 is slidably connected to the inner wall of the base 1. The bracket 27 and the opposite side of the friction wheel 25 are commonly connected to a torsion spring 28. The side of the bracket 27 is fixedly connected to an electric push rod 29. The outer shell of the electric push rod 29 is fixedly connected to the inner wall of the base 1. The friction wheel 25 is opposite to the friction wheel 1 22 and friction transmission is achieved.

[0066] The outer surface of the cam 30 is fixedly connected to the outer surface of the stabilizer bar 23, and the inner wall of the base 1 is fixedly connected to a piston mechanism 31. The piston mechanism 31 includes a piston cylinder, a piston rod, a piston head, a pressure plate 32, a spring 33, and an input pipe 34. The end of the hose 15 is fixedly connected to the outer surface of the piston cylinder, and a one-way valve is provided inside the hose 15 and the input pipe 34.

[0067] More specifically, in this embodiment: when the swivel 17 rotates forward, the corresponding conveyor belt assembly 3 performs normal conveying of the raw materials in the preparation of diaminodiphenyl ether, thereby driving the friction wheel 1 22 to rotate, and driving the connected friction wheel 25 to rotate under the friction transmission, thereby causing the torsion spring 28 to be continuously tightened. When the control panel controls the conveyor belt assembly 3 to stop running, the corresponding swivel 17 stops rotating, that is, it is in the process of unloading the raw materials. At this time, the control panel will immediately drive the telescopic part of the electric push rod 29 to retract, as shown in FIG. Figure 5 As shown, the friction wheel 25 connected to the friction wheel 1 22 is no longer aligned with the friction wheel 2 24, and the conveyor belt assembly 3 The driving motor used has a self-locking property, so the connecting friction wheel 25 will not reverse, and then under the friction transmission and the action of the stored force, the connecting friction wheel 25 is quickly reversed, so that the friction wheel 24 is quickly rotated, and then the stabilizing bar 23 and the cam 30 are driven to rotate. Due to the intermittent abutment relationship between the cam 30 and the pressure plate 32, and the elastic reset property of the spring 33, the piston rod and the piston head are reciprocated, so that the piston mechanism 31 starts to operate, so that air can be extracted or the external cleaning gas is sucked into the piston mechanism 31, and then input into the interior of the housing 13 through the hose 15, and finally the gas is sprayed toward the interior of the charging hopper 4 by the nozzle 14. The control panel pre-controls the time when the conveyor belt assembly 3 stops each time the material is unloaded, so that the reciprocating telescopic movement of the electric push rod 29 is completed during this time, thereby ensuring the normal operation of the subsequent device. This method has the following advantages:

[0068] First, it has an excellent automation effect. When the conveyor belt assembly 3 stops running, it automatically drives the subsequent mechanism to spray the cleaning gas to the downward charging hopper 4, thereby eliminating the need for the user to perform multiple steps. The overall mechanism has an excellent integration and intelligent form. It uses the operating power of the conveyor belt assembly 3 itself to store energy and has a switching form to complete the function of immediately operating the subsequent mechanism. Therefore, the structural connection in this device is more compact and the linkage is higher.

[0069] Secondly, since there may be multiple raw materials added during the preparation of diaminodiphenyl ether, and each time the loading hopper 4 dumps the raw materials, there may be residual raw materials. If the device is operated for a long time, that is, when the loading hopper 4 is continuously conveying, multiple raw materials may remain in the loading hopper 4, and a certain amount of manual maintenance of the loading hopper 4 is required, and the mixing ratio of the raw materials during the subsequent preparation of diaminodiphenyl ether may be affected. Therefore, this method adopts an automatic spraying method to clean the loading hopper 4, thereby ensuring that the loading hopper 4 can maintain a certain cleanliness after each use, which is conducive to the continuous preparation of diaminodiphenyl ether and is more practical.

[0070] Working principle: When the feeding device for preparing diaminodiphenyl ether is used, the following steps are involved:

[0071] S1: First, adjust the angle of the feeding device according to work needs. Under the action of the driving component, the user adjusts the elevation angle of the conveyor belt assembly 3 so that the conveyor belt assembly 3 can finally lean against and dock with the reaction device;

[0072] S2: After the driving mechanism is operated, the cleaning unit also follows the operation, thereby causing the cleaning unit to deflect accordingly and move laterally so that the cleaning unit is aligned with the used loading hopper 4;

[0073] S3: The user then puts the raw materials for preparing diaminodiphenyl ether into the loading hopper 4 and operates the conveyor belt assembly 3 to continuously input the raw materials into the reaction device. When the raw materials are poured, the conveyor belt assembly 3 is stopped to ensure sufficient discharge of the raw materials.

[0074] S4: When the conveyor belt assembly 3 is running, the operating mechanism will be operated and energy will be stored. When the conveyor belt assembly 3 stops running, the stored energy will be released immediately, driving the transmission mechanism to operate. The transmission mechanism will pressurize the cleaning gas and send it into the cleaning unit, so that the cleaning unit will spray towards the loading hopper 4 for cleaning.

[0075] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
