[0017] The present invention has the following beneficial effects:

[0018] 1. The present invention aims to solve the problem of lack of intelligent control means and adaptive adjustment of the conveying function according to the parameters of the transmission materials in the process of drop conveying of medium and thick plates:

[0019] On the one hand, through the structural design of the double-layer transmission roller table with end-to-end docking, the feeding control of the medium and thick plates in the heating furnace of the spheroidizing station is realized by the drop material receiving structure. Specifically, the smooth drop feeding of the medium and thick plates is stably realized through the continuous actions of receiving deflection, material stabilization and correction of deviation and centering, which effectively avoids the stress damage of the medium and thick plates during the drop conveying process and the deformation phenomenon of the collision with the heating furnace body after slipping; on the other hand, the intelligent control system completes the acquisition of relevant parameters in the real-time transmission and feeding process of the medium and thick plates, and outputs the execution action signal to control the medium and thick plates to realize the continuous conveying actions of receiving deflection, material stabilization and correction of deviation and centering, so as to achieve the function of adaptive adjustment according to the transmission material parameters in the drop transmission process of the medium and thick plates in the heating furnace of the spheroidizing station, and avoid the unstable transmission of the plates;

When the feeding tail end of the medium and thick plates breaks away from the transition wheel rod, the medium and thick plates at this time are only supported by one side of the receiving pallet, and the other side falls onto the bearing pad, so that the medium and thick plates can be stably placed on the surface composed of the receiving pallet and the bearing pad, thus completing the dropping process, and continuing to complete the drop feeding of the heating furnace through the conveying rollers on the lower roller assembly.

[0040] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. 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 creative work are within the scope of protection of the present invention.

[0041] Example 1: Reference Figure 1 - Fig.12As shown, a double-layer conveying roller for a spheroidizing station in this embodiment includes an upper roller assembly 1 and a lower roller assembly 2 arranged in layers, the upper roller assembly 1 and the lower roller assembly 2 have the same structure and the head and tail positions are connected and overlapped in the vertical direction by a fixing plate 5;

[0042] The upper roller assembly 1 and the lower roller assembly 2 each include a pair of side plates 11 and a bottom plate 12, the side plates 11 are embedded with a control panel, the end of the lower roller assembly 2 close to the upper roller assembly 1 is provided with a follow-up direction-changing assembly 4 for receiving the plate, and the inner tail position of the lower roller assembly 2 is provided with a synchronous deviation-correcting assembly 3 for guiding the plate;

[0043] Reference Figure 8 and Fig.11 As shown, the follow-up direction-changing assembly 4 includes a receiving support plate 41 and a wear bearing box 42 which are slidably and rotatably arranged on the side plate 11, and an electric push rod 43 is symmetrically installed on the outer side of the side plate 11 corresponding to the receiving support plate 41, and a linkage rod 46 is installed in the middle of both sides of the receiving support plate 41, and a connecting pin plate 47 which is rotatably connected to the linkage rod 46 is installed at the output end of the electric push rod 43;

[0044] The electric push rod 43 is arranged on the outer side of the side plate 11, and the linkage rod 46 slides with the side plate 11 through a sliding slot. When the electric push rod 43 drives the connecting pin plate 47 to move horizontally, the linkage rod 46 also drives the receiving support plate 41 to move horizontally between the pair of side plates 11.

[0045] It is necessary to add that: refer to Figure 8 As shown, a transmission box 45 is installed outside one of the connecting pin plates 47, and a second motor 44 is installed outside the transmission box 45. The second motor 44 is started to drive the receiving support plate 41 to achieve deflection (wherein the transmission box 45 is provided with conventional settings in the prior art, and transmission is achieved here by using a synchronous belt and a pulley sleeve connection, which will not be repeated here). Referring to the above, when the electric push rod 43 drives the receiving support plate 41 to move horizontally, the start of the second motor 44 can also drive the receiving support plate 41 to deflect through the transmission box 45, and change the inclination angle of the horizontal bearing part on the receiving support plate 41, which corresponds to the length of the medium and thick plate material fed through the upper roller assembly 1. The position of the blanking finally achieves stable material connection;

[0046] Reference Fig.11 As shown, a plurality of elastic hoist rods 48 are arranged inside the platform of the wear carrying box 42, and a bearing pad 49 flush with the top of the platform of the wear carrying box 42 is installed on the upper end of the elastic hoist rod 48, and the bearing rear horizontal surface of the bearing pad 49 is flush with the inner horizontal surface of the receiving pallet 41;

[0047] After receiving the material, the medium and thick plate is stably placed by the conveying roller 17, the transition wheel rod 19 and the upper platform of the receiving pallet 41, and the receiving pallet 41 is deflected during the continuous horizontal displacement of the electric push rod 43, so that the upper platform of the receiving pallet 41 always coincides with the tangent extension line of the conveying roller 17 and the transition wheel rod 19, ensuring the stable dropping of the medium and thick plate;

[0048] When dropping: When the feeding tail end of the medium and thick plate is separated from the transition wheel rod 19, the medium and thick plate is only supported by one side of the receiving support plate 41, and the other side falls onto the bearing pad 49, so that the medium and thick plate can be stably placed on the surface composed of the receiving support plate 41 and the bearing pad 49, and the dropping process is completed. The conveying roller 17 on the lower roller assembly 2 continues to complete the drop feeding of the heating furnace. For details, refer to Figure 5 - Figure 7 Feeding diagram of

[0049] In addition, a synchronous deviation correction component 3 is provided for the medium and thick plates after drop feeding, see Fig.10 As shown, the synchronous deviation correction component 3 includes a deviation correction plate 33 and a guide plate 34 which are staggered and symmetrically arranged. The synchronous deviation correction component 3 also includes a driving component symmetrically arranged below the side plate 11. The driving component includes a staggered motor 35. A pair of motors 35 are connected to the output ends of the motors 35. The outer sleeve of the screw 36 is provided with a movable sleeve 37. The end of the movable sleeve 37 is provided with an extension frame 38 connected to the deviation correction plate 33. A fixed plate 31 for installing the motor 35 is provided on the lower side of the lower roller assembly 2. A top plate 32 is installed on the upper side of the lower roller assembly 2. The movable sleeve 37 is slidably connected to the fixed plate 31, and the extension frame 38 is slidably connected to the top plate 32.

[0050] During deviation correction: at this time, the medium and thick plates dropped onto the lower roller assembly 2 will inevitably be skewed due to the drop feeding, and it is easy to collide with the side plate 11 when the conveying roller 17 does not have a deviation correction function. At this time, the distance between the two deviation correction plates 33 is determined according to the width of the medium and thick plates, and the medium and thick plates can be guided and moved between the deviation correction plates 33 through the guide plate 34 to ensure stable feeding of the medium and thick plates.

[0051] Basic principle: The principle of the present invention is basically similar to that of traditional transmission rollers in the prior art, and the difference lies in: the structural design of the double-layer transmission roller of the present invention is arranged end to end, and the feeding control of the medium and thick plates in the heating furnace in the spheroidizing station is realized through the drop material receiving structure. Specifically, the smooth drop feeding of the medium and thick plates is stabilized through the continuous actions of material receiving deflection, drop stabilization and correction and centering, which effectively avoids stress damage in the process of drop transportation of the medium and thick plates and deformation after slipping and hitting the heating furnace body.

[0052] Embodiment 2: This embodiment is combined with Embodiment 1 to further optimize the control process intelligently.

[0053] The control panel is built with an integrated module, which includes a parameter acquisition unit, a parameter processing and analysis unit, a blanking execution unit and a processor that are communicatively connected. The parameter acquisition unit is used to obtain the length and width values ​​of the medium and thick plate on the conveying roller 17 of the upper roller assembly 1, wherein the length and width values ​​are measured by the photoelectric sensor arranged on the side plate 11, and the length and width values ​​are sent to the parameter processing and analysis unit through the processor to analyze the drop feed matching degree of the medium and thick plate. The analysis process is as follows:

[0054] S1: The parameter processing and analysis unit obtains the length value L and the width value D during the feeding of the medium and thick plate, and obtains the travel deviation coefficient after numerical calculation of the length value and the width value;

[0055] S2: Construct the calculation formula of the travel deviation coefficient XP, Wherein v is the current conveying speed of the conveying roller 17, a, b and c are all preset proportional factor coefficients, and a>b>c>0, and k is a preset correction factor coefficient and k>0;

[0056] S3: Comparing and analyzing the traveling deviation coefficient with the traveling deviation standard value preset by the processor to generate a direction change control signal and a synchronous deviation correction signal, the direction change control signal includes a forward control signal and a reverse control signal;

[0057] If the travel deviation coefficient is greater than the travel deviation standard value, it means that the current drop feed of the medium and thick plate produces a load loss, and a positive control signal is generated at this time. The parameter processing and analysis unit sends the positive control signal to the blanking execution unit, and the blanking execution unit sends the positive control signal output control signal to the electric push rod 43 and the motor 2 44;

[0058] The electric push rod 43 starts to extend and drives the receiving pallet 41 to move horizontally close to the drop point of the medium and thick plate. The motor 2 44 starts to drive the receiving pallet 41 to tilt to an angle that coincides with the extension line of the conveying roller 17 and the transition wheel rod 19. After the front end of the medium and thick plate stably falls into the receiving pallet 41, the conveying roller 17 continues to rotate to drive the medium and thick plate to feed, and the electric push rod 43 contracts to drive the receiving pallet 41 to move in the feeding direction until the rear end of the medium and thick plate falls onto the bearing pad 49 and stops.

[0059] If the travel deviation coefficient is less than the travel deviation standard value, it means that the current medium and thick plate drop feeding produces overload, and a reverse control signal is generated at this time. The parameter processing and analysis unit sends the reverse control signal to the blanking execution unit, and the blanking execution unit sends the reverse control signal output control signal to the electric push rod 43 and the motor 2 44;

[0060] The electric push rod 43 starts to retract and drives the receiving pallet 41 to move horizontally close to the drop point of the medium and thick plate. The motor 2 44 starts to drive the receiving pallet 41 to tilt to an angle that coincides with the extension line of the conveying roller 17 and the transition wheel rod 19. After the front end of the medium and thick plate stably falls into the receiving pallet 41, the conveying roller 17 continues to rotate to drive the medium and thick plate to feed, and the electric push rod 43 continues to retract to drive the receiving pallet 41 to move in the feeding direction until the rear end of the medium and thick plate falls onto the bearing pad 49 and stops.

[0061] If the travel deviation coefficient = the travel deviation standard value, it means that the current medium and thick plate is fed to the initial position of the receiving pallet 41 by a drop, and no signal is generated.

[0062] It is important to explain that after the thick and medium-sized plates are dropped, the motor 2 44 drives the receiving plate 41 to deflect through the transmission box 45. When the supporting platform of the receiving plate 41 deflects downward, the thick and medium-sized plates are separated and carried on the conveying roller 17. At this time, the conveying roller 17 drives the thick and medium-sized plates to be fed under the continuous rotation.

[0063] Reference Figure 7 As shown, during the feeding process, according to the width of the medium and thick plate and the generated synchronous correction signal, the motor 35 drives the screw rod 36 to rotate, and the movable sleeve 37 outside the screw rod 36 moves, and then the correction plate 33 is driven to change its position through the extension frame 38 until it matches the width of the medium and thick plate, and finally completes the precise drop feeding of the medium and thick plate into the heating furnace.

[0064] Embodiment 3: This embodiment combines the technical contents of Embodiment 1 and Embodiment 2 to form the following control method:

[0065] Step 1: The medium and thick plate is unloaded and conveyed from the upper roller assembly 1 until it passes through the last conveying roller 17 and turns downward and contacts the transition wheel rod 19;

[0066] Step 2: The length and width values ​​are obtained during the conveying process of medium and thick plates. The integrated module analyzes and calculates the travel deviation coefficient, and simultaneously generates a direction change control signal and a synchronous deviation correction signal. The direction change control signal and the synchronous deviation correction signal are sent out and related actions are executed to ensure the stable drop feeding and blanking of medium and thick plates.

[0067] Step 3: In the above step 2, when the medium and thick plate parameters generate a positive control signal, the positive control signal outputs a control signal to the electric push rod 43 and the motor 2 44, the electric push rod 43 starts to extend and drives the receiving pallet 41 to move horizontally close to the drop point of the medium and thick plate, the motor 2 44 starts to drive the receiving pallet 41 to tilt to an angle that coincides with the extension line of the conveying roller 17 and the transition wheel rod 19, after the front end of the medium and thick plate feeding stably falls into the receiving pallet 41, the conveying roller 17 continues to rotate to drive the medium and thick plate to feed, and the electric push rod 43 contracts to drive the receiving pallet 41 to move in the feeding direction until the rear end of the medium and thick plate falls to the bearing pad 49 and stops;

[0068] Step 4: In the above step 2, when the medium and thick plate parameters generate a reverse control signal, the reverse control signal output control signal is sent to the electric push rod 43 and the motor 2 44, the electric push rod 43 starts to shrink and drives the receiving pallet 41 to move horizontally close to the drop point of the medium and thick plate, the motor 2 44 starts to drive the receiving pallet 41 to tilt to an angle that coincides with the extension line of the conveying roller 17 and the transition wheel rod 19, after the front end of the medium and thick plate feeding falls stably into the receiving pallet 41, the conveying roller 17 continues to rotate to drive the medium and thick plate to feed, and the electric push rod 43 continues to shrink to drive the receiving pallet 41 to move in the feeding direction until the rear end of the medium and thick plate falls to the bearing pad 49 and stops;

[0069] Step 5: After the thick plate is dropped, the motor 2 44 drives the receiving plate 41 to deflect through the transmission box 45. When the supporting platform of the receiving plate 41 deflects downward, the thick plate is separated and carried on the conveying roller 17. At this time, the conveying roller 17 continues to rotate and drives the thick plate to be fed;

[0070] Step six: During the feeding process, according to the width of the medium and thick plate and the generated synchronous correction signal, the motor 35 drives the screw rod 36 to rotate, and the movable sleeve 37 outside the screw rod 36 moves horizontally. The movable sleeve 37 drives the extension frame 38 and the correction plate 33 to change their positions until they match the width of the medium and thick plate. The medium and thick plate can move between the correction plates 33 through the front guide plate 34 and complete the adapted centering feeding, ultimately ensuring the precise drop feeding of the medium and thick plate into the heating furnace.

[0071] The above formulas are obtained by collecting a large amount of data for software simulation and selecting a formula that is close to the actual value. The coefficients in the formula are set by technical personnel in this field according to actual conditions. The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited to this. Any technical personnel familiar with the technical field within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, make equivalent replacement or change, which should be covered within the protection scope of the present invention.
