[0042] It should be understood that the specific embodiments described herein are merely intended to explain the technical solutions of the present application, and are not intended to limit the present application.

[0043] In order to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0044] It should be noted that all the direction indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the direction indications will also change accordingly. It should be understood that although the steps in the flowchart in the embodiments of the present application are displayed in sequence according to the arrows, these steps are not necessarily executed in sequence according to the arrows. Unless otherwise specified herein, the execution of these steps has no strict sequence limitation, and they can be executed in other sequences.

[0045] It should be understood that for some materials that need to be heated before processing, they need to be conveyed to the processing machine by the feeding machine after being heated. In this process, the feeding machine will heat the temperature of the materials in the conveying process through the heating assembly. However, in the actual working process, this heating method is generally overall heating, which may cause the temperature of some materials in the same batch to be too high during conveying, thereby affecting the quality of the materials.

[0046] It can be understood that in actual situations, after a batch of materials to be processed, such as plastics, metals, etc., are processed by the heating furnace, the heating furnace will move to the feeding machine and move the same batch of materials out of the furnace to the feeding machine for conveying. In the conveying process, the temperature of the materials to be processed needs to be kept within a certain temperature range and cannot be too high or too low. Generally speaking, the temperature of the materials to be processed arranged on both sides of the same batch of materials out of the furnace will drop faster, and the temperature of the materials to be processed in the middle will drop slower. In order to ensure that the temperature of the materials to be processed on both sides will not be too low, the feeding machine can only increase the working power of the heating assembly based on the temperature of the materials to be processed on both sides. However, because it is overall heating, this may cause the temperature of the materials to be processed in the middle to be too high, thereby affecting the quality of the materials to be processed.

[0047] Therefore, the present application provides a heating control method of a feeding machine. The feeding machine includes a housing, a feeding port and a discharging port are arranged on both sides of the housing respectively, a feeding channel is arranged between the feeding port and the discharging port in the housing, the feeding machine further includes a material placing tray for placing a plurality of heated materials to be processed, the material placing tray is driven by a driving assembly to move on the feeding channel between the feeding port and the discharging port so as to convey the plurality of materials to be processed from the feeding port to the discharging port or from the discharging port to the feeding port; a plurality of heating zones are further arranged on the material placing tray, each heating zone is provided with a heating assembly, the plurality of heating zones are arranged along a first direction, the first direction is a direction in which the feeding port points to the discharging port; and the plurality of materials to be processed are arranged side by side on the material placing tray along the first direction.

[0048] Reference Figure 6, the feeding tray can be implemented by a metal tray, the feeding channel can be composed of two guide rails, a driving assembly such as a motor is arranged on the guide rails, a sliding groove can be arranged at the bottom of the feeding tray to be clamped into the guide rails and fixed together with the driving assembly, so that the control device can control the driving assembly to drive the feeding tray to move on the guide rails, that is, by controlling the driving assembly to drive the feeding tray to move on the feeding channel between the feeding port and the discharging port. The heating assembly can be implemented by a metal heating assembly, a ceramic heating assembly, an electromagnetic induction heating assembly, etc. For example, the metal heating assembly is arranged at the bottom side of the feeding tray, and an electric current is supplied to it to make it heat according to a certain working to provide heat for the material to be processed. A plurality of power modules, such as a plurality of constant current output modules, for supplying electric current to each heating assembly can also be arranged in the feeding machine, and the control device can control the plurality of power modules to output corresponding electric current to each heating assembly.

[0049] The control device can be implemented by an MCU, a DSP (Digital Signal Process), an FPGA (Field Programmable Gate Array), a PLC, a SOC (System On Chip), etc.

[0050] Reference Figure 1 In an embodiment of the present application, the heating control method of the feeding machine comprises:

[0051] Step S100, obtaining the temperature of each material to be processed on the feeding tray;

[0052] In this embodiment, the temperature of each material to be processed can be obtained by placing a contact temperature sensor such as NTC, PTC, etc. on the feeding tray. Alternatively, in another embodiment, the feeding machine comprises an infrared detection unit, and the step S100 of obtaining the temperature of each material to be processed on the feeding tray comprises: obtaining the temperature of each material to be processed on the feeding tray through the infrared detection unit. In this embodiment, the control device can determine the corresponding temperature of each material to be processed based on the infrared radiation value detected by the infrared detection unit.

[0053] Step S200, in the case that the feeding tray is switched from the stopped state to the moving state from the feeding port, based on the temperature of the material to be processed in each heating zone and the position of the heating zone on the feeding tray, the target heating power corresponding to the heating zone is determined;

[0054] Step S300, controlling the heating assembly of each heating zone to work according to the corresponding target heating power, so that the temperature of the plurality of materials to be processed is maintained within the preset temperature range during the movement along the feeding channel from the feeding port to the discharging port.

[0055] In the present embodiment, it can be understood that, since the just-finished-to-be-processed material is not immediately transferred to the material placing tray by other driving members, the control device is configured to ensure that the temperature of each to-be-processed material is better maintained in a preset temperature range (the range is the temperature range required by the to-be-processed material). The control device determines the target heating power of each heating zone at the moment when the driving assembly starts to drive the material placing tray to move from the feeding port to the discharging port. Alternatively, in an embodiment, referring to Figure 2 , the step of determining the target heating power of each heating zone based on the temperature of the to-be-processed material in each heating zone and the position of the heating zone on the material placing tray comprises:

[0056] Step S210, obtaining a first temperature corresponding to each heating zone; wherein the first temperature is the lowest one of the temperatures of all to-be-processed materials in the heating zone;

[0057] Step S210, determining a first heating power corresponding to each heating zone in a preset first temperature-heating zone position-first heating power mapping table based on the first temperature of each heating zone and the position of each heating zone on the material placing tray, and setting the first heating power as the target heating power;

[0058] Wherein, the plurality of heating zones are arranged on the material placing tray along a first direction, a heating zone close to the feeding port in the plurality of heating zones is a first heating zone, a heating zone close to the discharging port is a second heating zone, and a plurality of intermediate heating zones are arranged between the first heating zone and the second heating zone;

[0059] In the preset first temperature-heating zone position-first heating power mapping table, at the same first temperature, the first heating power corresponding to the plurality of intermediate heating zones is uniform, the first heating power corresponding to the second heating zone is greater than the first heating power corresponding to the first heating zone, and the first heating power corresponding to the first heating zone is greater than the first heating power corresponding to the intermediate heating zone

[0060] In the present embodiment, the first temperature corresponding to each heating zone is set as the lowest one among the temperatures of all the materials to be processed on each heating zone, so as to ensure that the control device can ensure that the lowest temperature of the material to be processed is within the preset temperature range during the subsequent control of the heating assembly to work according to the target heating power. It can be understood that, due to the different arrangement positions of different heating zones on the material placing tray, the temperature change of the material to be processed on different heating zones during the conveying process is also different. For example, the first heating zone and the second heating zone on both sides will have a relatively faster temperature drop than the heating zones in the middle because they have a larger contact area with the external air (because there is no other heating zone beside them), and the second heating zone will have a relatively faster temperature drop than the first heating zone because it is windward when the material placing tray moves. In other words, at the same first temperature, the second heating zone needs a larger heating power than the first heating zone, and the first heating zone needs a larger heating power than the heating zones in the middle. Meanwhile, at the same heating zone, the higher the first temperature, the lower the required heating power. Therefore, during the development period, the developer will conduct a large number of experiments based on the preset temperature range of the material to be processed to be conveyed and for the purpose of ensuring that the material to be processed remains within the preset temperature range during the conveying process, and then obtain the above-mentioned preset first temperature-heating zone position-first heating power mapping table and pre-store it in the control device. The control device will determine the first heating power corresponding to each heating zone in the preset first temperature-heating zone position-first heating power mapping table based on the first temperature of each heating zone and the position of each heating zone on the material placing tray, and set the first heating power as the target heating power. Subsequently, the control device will control the power module to output a corresponding working current to the heating assembly corresponding to each heating zone based on the pre-stored heating assembly working current-heating power mapping table (which can be tested and obtained or directly based on the specification of the heating assembly), so as to make the heating power of each heating zone reach the target heating power, thereby keeping the temperature of the plurality of materials to be processed within the preset temperature range during the movement of the materials to be processed along the feeding channel from the feeding port to the discharging port. In this way, through the above setting, during the conveying of a plurality of different materials to be processed, the feeding machine of the present application can adaptively perform zoned heating according to the temperature of the material to be processed in different heating zones and the position of the heating zone based on the heating control method of the feeding machine of the present application, so as to keep the temperature of each material to be processed within the preset temperature range during the conveying of the material to be processed from the feeding port to the discharging port. Compared with the overall heating in the prior art, the accuracy and adaptability of temperature control of the material to be processed are improved during the feeding of a plurality of materials to be processed.

[0061] In addition, it can be understood that in actual situations, the time for discharging the furnace varies in different situations, and the time for processing the material to be processed after feeding varies in different situations. Therefore, in order to adapt to the actions of the furnace and the processing of the material to be processed in the subsequent stage, the control device in the feeding machine of the present application can also adjust the working parameters of the driving assembly based on the setting requirements of the user, for example, adjust the frequency of the driving current output to the motor, to change the moving speed of the discharging tray driven by the driving assembly on the feeding channel. Therefore, in an embodiment of the present application, referring to Figure 3 , the step of controlling the heating assembly of each heating zone to work according to the corresponding target heating power further comprises:

[0062] Step S310, the moving speed of the discharging tray in the moving state is obtained, and a corresponding first power adjustment value is determined based on the moving speed; wherein the moving speed and the first power adjustment value are in a positive correlation;

[0063] Step S320, the current target heating power of each heating zone is reduced by the first power adjustment value and updated, and the heating assembly of each heating zone is controlled to work according to the updated target heating power.

[0064] In the present embodiment, the control device can determine the moving speed of the discharging tray based on the moving speed of the discharging tray determined by the above process or the speed detection sensor arranged on the discharging tray. Then, based on the moving speed-first power adjustment value mapping table preset by the R&D personnel, the corresponding first power adjustment value is determined. And the current target heating power of each heating zone is reduced by the first power adjustment value and updated, and the heating assembly of each heating zone is controlled to work according to the updated target heating power. It can be understood that the faster the moving speed, the faster the material to be processed will move from the feeding port to the discharging port, that is, the heat loss in the transmission process will be smaller, so the control device can appropriately reduce the current target heating power to achieve the purpose of energy saving. Of course, it can be understood that for the heating control method of the feeding machine of the present application, in the energy saving control process in the above embodiment or the following embodiment, if the temperature of any material to be processed approaches the lower limit value of the preset temperature interval, such as the difference is less than the dangerous difference (preset by the R&D personnel), the control device will control the corresponding heating assembly to restore to the target heating power determined in step S200, so as to ensure that the temperature of the plurality of materials to be processed is maintained within the preset temperature interval during the movement along the feeding channel from the feeding port to the discharging port.

[0065] It needs to be understood that the plurality of materials to be processed on the same discharging tray are generally relatively close to each other. In other words, the heat between adjacent materials to be processed will also be transmitted to each other. Therefore, referring to Figure 4In an embodiment of the present application, the step of controlling the heating assembly of each heating zone to work according to the corresponding target heating power further comprises:

[0066] In step S330, if the temperature of any to-be-processed material is within the preset temperature range and the temperatures of its adjacent to-be-processed materials are both higher than its own temperature and the difference between any of the two and the to-be-processed material is greater than the preset temperature difference, the to-be-processed material is set as the first to-be-processed material.

[0067] In step S340, the target heating power of the heating zone where the first to-be-processed material is located is updated by reducing the second power adjustment value, and the heating assembly of the heating zone where the first to-be-processed material is located is controlled to work according to the corresponding updated target heating power.

[0068] In the embodiment, the control device acquires the temperature of each to-be-processed material based on the above-mentioned temperature detection process. If the temperature of a to-be-processed material is within the preset temperature range and the temperatures of its adjacent to-be-processed materials are both higher than its own temperature and the difference between any of the two and the to-be-processed material is greater than the preset temperature difference (set by the developer), for example, in the same heating zone, the temperatures of the to-be-processed materials on both sides of the to-be-processed material are both higher than its own temperature and the difference between any of the two and the to-be-processed material is greater than the preset temperature difference, or in the adjacent two heating zones, the temperatures of the to-be-processed materials adjacent to the to-be-processed material on both sides are both higher than its own temperature and the difference between any of the two and the to-be-processed material is greater than the preset temperature difference. Then, the control device sets the to-be-processed material as the first to-be-processed material and considers that the temperature difference between the first to-be-processed material and the to-be-processed materials on both sides is relatively large, so that the to-be-processed materials on both sides can be considered to provide more heat to the to-be-processed material with lower temperature to reduce the heat provided by the heating assembly and achieve the effect of energy saving. At this time, the control device updates the target heating power of the heating zone where the first to-be-processed material is located by reducing the second power adjustment value (set by the developer in advance) and then adjusts the working current of the heating assembly of the heating zone where the first to-be-processed material is located so that the heating assembly works according to the corresponding updated target heating power. In this way, since the temperatures of the to-be-processed materials on both sides of the to-be-processed material are both relatively high and they are both within the preset temperature range, and it can be known from the above-mentioned content that the target heating power is set according to the lowest temperature of the to-be-processed material on each heating zone when the material placing tray is just moved (that is, for other to-be-processed materials with higher temperature, the target heating power is relatively excessive to meet the requirement of maintaining the temperature), so that the to-be-processed materials with higher temperature can provide certain heat to the to-be-processed material with lower temperature within a certain period of time. In other words, in this case, the corresponding heating assembly can reduce the provision of this part of heat, that is, the control device reduces the working power of the heating assembly in the above-mentioned case, thereby achieving the effect of energy saving.

[0069] Furthermore, in order to prevent the situation that the collective temperature of the to-be-processed materials is too low due to the power reduction, and the temperature is below the preset temperature range, with reference to Figure 5 In an embodiment of the present application, between the step S330 and the step S340, the step of controlling the heating assembly of each heating zone to work according to the corresponding target heating power further comprises:

[0070] S350, obtaining the moved distance of the feeding tray on the feeding channel;

[0071] S360, if the moved distance is less than half of the length of the feeding channel, the step S340 is not executed;

[0072] S370, if the moved distance is more than half of the length of the feeding channel, and there are at least two first to-be-processed materials in the same feeding area or there are first to-be-processed materials in adjacent feeding areas, the step S340 is not executed;

[0073] S380, if the moved distance is more than half of the length of the feeding channel, and there is only one first to-be-processed material in the same feeding area and there is no first to-be-processed material in adjacent feeding areas, the step S340 is executed.

[0074] In the embodiment, the control device first determines the moved distance of the current feeding tray. The moved distance can be determined by setting a contact sensor at the position of half of the feeding channel, such as an infrared reflection sensor, a grating sensor, a trigger switch, etc. During the process of moving the feeding tray from the discharge port to the feeding port, if the contact sensor is triggered, the control device determines that the moved distance of the current feeding tray reaches half of the feeding channel. If there are at least two first materials to be processed in the same feeding area (in this case, the control device determines that too many first materials to be processed will cause the temperature of other materials to be processed in the heating area to drop too quickly, which has a certain risk) or if the adjacent feeding area is also placed with first materials to be processed (in this case, the control device determines that the target heating power of the adjacent heating area is simultaneously reduced, which has a certain risk of causing the temperature of the materials to be processed to drop too quickly), the step S340 is not performed. If the moved distance reaches half of the feeding channel, if there is only one first material to be processed in the same feeding area and there is no adjacent feeding area with first materials to be processed, the step S340 is performed. At the same time, if the contact sensor is not triggered, the control device determines that the moved distance of the current feeding tray does not reach half of the feeding channel, and the step S340 is not performed. In this way, through the above setting, the feeding machine of the application can achieve a good balance between energy saving and ensuring the temperature of the materials to be processed.

[0075] It should be understood that for some materials to be processed, especially for active metals or high-precision and high-purity materials to be processed, they may react with air during the feeding process and cause the quality to decrease. Therefore, in an embodiment of the application, the housing is further provided with an air inlet and an air outlet, the air inlet and the feeding port are arranged on the same side, the air outlet is arranged on the upper side of the housing, and the feeding machine further comprises a blowing module connected with the air inlet.

[0076] The heating control method of the feeding machine further comprises:

[0077] In step S400, during the process of moving the plurality of materials to be processed on the feeding tray along the feeding channel from the feeding port to the discharge port by the driving assembly, the blowing module inputs inert gas through the air inlet.

[0078] In the embodiment, when the material to be processed conveyed by the material tray needs to be protected by inert gas, the control device can control the air supply module to work during the movement of the material tray on the feeding channel, for example, the fan and the inert gas storage bottle, so as to input inert gas, for example, argon, from the air inlet. Since the density of argon is greater than that of air, argon will deposit in the lower layer in the shell and part of the air will be sent out of the shell through the air outlet, so that the material to be processed on the material tray will be wrapped by argon during the conveying process, thereby playing a protective role on the material to be processed to prevent it from contacting with air.

[0079] Further, it can be understood that, since the feeding port and the air inlet are on the same side, the material to be processed arranged on the first heating zone of the material tray will be in direct contact with the inert gas blown by the air inlet and the contact area is relatively large, so that the temperature may decrease relatively fast. Therefore, in an embodiment of the present application, the step of controlling the heating assembly of each heating zone to work according to the corresponding target heating power further comprises:

[0080] Step S390, increasing the current target heating power of the first heating zone by a third power adjustment value and updating, and controlling the heating assembly corresponding to the first heating zone to work according to the updated target heating power.

[0081] In the embodiment, the third power adjustment value can be preset by the developer in advance. When the air supply module is controlled by the control device to start inputting inert gas, the control device will increase the current target heating power of the first heating zone by the third power adjustment value and update. For example, the current target heating power corresponding to the current first heating zone is α kW, and the third power adjustment value is a kW, so the control device will increase the current target heating power of the first heating zone by a kW and update, that is, the target heating power of the first heating zone is updated to (α + a) kW. a) kW as a new target heating power, and then adjusting the working current of the heating module based on the process of the above embodiment according to the new target heating power, so as to realize the control of the heating assembly corresponding to the first heating zone to work according to the updated target heating power. It can be understood that the third power adjustment value can be obtained by the R&D personnel through multiple experiments during the R&D period, so that after increasing the third power adjustment value, the temperature of the material to be heated on the current first heating zone can be maintained within the preset temperature range during the movement along the feeding channel from the feeding port to the discharge port. Wherein, the third power adjustment value can be a constant value, or a fluctuating value adjusted adaptively according to the air inlet flow of the air inlet, for example, the larger the air inlet flow, the larger the third power adjustment value. In this way, through the above setting, in actual application, for a specific material to be processed, the feeding machine of the present application not only can protect the material to be processed by passing in inert gas, but also can increase the target heating power of the first heating zone corresponding to the largest and windward contact surface with the inert gas during the process of passing in the inert gas, so as to further ensure that the temperature of the material to be processed in this area is maintained within the preset temperature range during the movement along the feeding channel from the feeding port to the discharge port, and the quality of the material to be processed is ensured.
