[0019] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0020] In order to better understand the technical solutions of this application, the following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement, etc. between the various components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. It should be understood that although the various steps in the flowcharts in the embodiments of the present application are displayed in sequence as indicated by the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and they can be executed in other orders.

[0022] It's important to understand that some materials that require heating before processing are transported to the processing machine via a feeding mechanism. During this process, the feeding mechanism uses heating components to control the temperature of the materials being transported. However, in practice, this heating method generally heats the entire batch, which can cause some of the materials in the same batch to become overheated during the feeding process, affecting their quality.

[0023] It is understandable that in actual situations, after a batch of materials to be processed, such as plastics and metals, are processed by a heating furnace, the materials will be moved to a feeding machine, and the feeding machine will move the materials to be processed in the same batch out of the furnace to the feeding machine for transmission. During the transmission process, the materials to be processed need to be kept in 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 will drop faster, while the temperature of the materials to be processed in the middle will drop more slowly. In order to ensure that the temperature of the materials to be processed on both sides is not too low, the feeding machine can only use it as a basis to increase the working power of the heating component. However, because it is an overall heating, doing so may cause the temperature of the materials to be processed in the middle to be too high, thus affecting its quality.

[0024] To this end, the present application proposes a heating control method for a feeding machine, wherein the feeding machine includes a shell, a feeding port and a discharge port are respectively provided on both sides of the shell, and a feeding channel is provided in the shell corresponding to the feeding port and the discharge port. The feeding machine also includes a discharge tray for placing a plurality of heated materials to be processed, and the discharge tray is driven by a driving component to move on the feeding channel between the feeding port and the discharge port to transfer the plurality of materials to be processed from the feeding port to the discharge port or from the discharge port to the feeding port; a plurality of heating zones are also provided on the discharge tray, each heating zone is provided with a heating component, and the plurality of heating zones are arranged along a first direction, and the first direction is the direction in which the feeding port points to the discharge port; a plurality of materials to be processed are placed side by side along the first direction on the discharge tray.

[0025] refer to Figure 6 The discharge tray can be implemented by a metal tray, and the feeding channel can be composed of two guide rails. A driving component such as a motor is provided on the guide rails. A slide groove can be provided at the bottom of the discharge tray to engage with the guide rails and be fixed to the driving component, so that the control device can control the driving component to drive the discharge tray to move on the guide rails, that is, to drive the discharge tray to move on the feeding channel between the feeding port and the discharging port by controlling the driving component. The heating component can be implemented by a metal heating component, a ceramic heating component, an electromagnetic induction heating component, etc. For example, a metal heating component is provided on the bottom side of the discharge tray, and when current is passed through it, it generates heat according to a certain working principle to provide heat for the material to be processed. The feeding machine can also be provided with multiple power modules for providing current to each heating component, such as multiple constant current output modules. The control device can control the multiple power modules to output corresponding current to each heating component.

[0026] Among them, the control device can be implemented by MCU, DSP (Digital Signal Process, digital signal processing chip), FPGA (Field Programmable Gate Array, programmable logic gate array chip), PLC, SOC (System On Chip, system-on-chip), etc.

[0027] refer to Figure 1 In one embodiment of the present application, the heating control method of the feeding machine includes: Step S100, obtaining the temperature of each material to be processed on the material placement tray; In this embodiment, a contact temperature sensor, such as an NTC or PTC temperature sensor, can optionally be placed on the unloading tray to obtain the temperature of each material to be processed. Alternatively, in another embodiment, the feeder includes an infrared detection unit, and step S100 of obtaining the temperature of each material to be processed on the unloading tray includes obtaining the temperature of each material to be processed on the unloading tray via 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.

[0028] Step S200, when the unloading tray switches from a stopped state to a moving state from the feeding port, determining a target heating power corresponding to each heating zone based on the temperature of the material to be processed in each heating zone and the position of the heating zone on the unloading tray; Step S300: Control the heating components of each heating zone to operate according to the corresponding target heating power, so that the temperature of the plurality of materials to be processed is maintained within a preset temperature range during the process of moving from the feeding port to the discharging port along the feeding channel.

[0029] In this embodiment, it is understandable that since the material to be processed that has just been taken out of the oven cannot be immediately transferred to the discharge tray by other transmission components, the control device determines the target heating power corresponding to each heating zone at the moment when the drive component is just controlled to drive the discharge tray to start moving from the feed port to the discharge port. Optionally, in one embodiment, refer to Figure 2 The step of determining the target heating power corresponding to each heating zone based on the temperature of the material to be processed in each heating zone and the position of the heating zone on the material discharge tray includes: Step S210: Obtain a first temperature corresponding to each heating zone; wherein the first temperature is the lowest temperature of all the materials to be processed in the heating zone; Step S210: Based on the first temperature of each heating zone and the position of each heating zone on the unloading tray, determine the first heating power corresponding to each heating zone in a preset first temperature-heating zone position-first heating power mapping table, and set the first heating power as the target heating power; Among them, multiple heating zones are arranged on the discharge tray along a first direction, the heating zone close to the feeding port among the multiple heating zones is the first heating zone, the heating zone close to the discharging port is the second heating zone, and multiple intermediate heating zones are arranged between the first heating zone and the second heating zone; In the preset first temperature-heating zone position-first heating power mapping table, at the same first temperature, the first heating powers corresponding to the plurality of intermediate heating zones are consistent, 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. In this embodiment, the first temperature for each heating zone is set to the lowest temperature among all the materials being processed in that zone. This ensures that when the control device subsequently controls the heating assembly to operate at the target heating power, the lowest temperature material remains within the preset temperature range. It will be appreciated that, due to the different locations of the heating zones on the unloading tray, the temperature of the materials in different heating zones will vary during transport. For example, the first and second heating zones on the sides have greater exposure to the outside air (because there are no other heating zones nearby), so their temperatures will drop faster than the central heating zone. Furthermore, the second heating zone faces wind during the unloading tray's movement, so its temperature drops faster than the first heating zone. In other words, if different heating zones have the same first temperature, the second heating zone will require a higher heating power than the first heating zone, and the first heating zone will require a higher heating power than the central heating zone. Furthermore, within the same heating zone, the higher the first temperature, the lower the required heating power. Therefore, during the development process, researchers conduct extensive experiments based on the preset temperature range of the materials to be processed, with the goal of ensuring that the materials remain within this preset temperature range during transport. This results in the development of the preset first temperature-heating zone position-first heating power mapping table, which is pre-stored in the control device. Based on the first temperature of each heating zone and its position on the material unloading tray, the control device determines the first heating power corresponding to each heating zone within the preset first temperature-heating zone position-first heating power mapping table and sets the first heating power as the target heating power. Subsequently, based on a pre-stored heating element operating current-heating power mapping table (which can be obtained through testing or directly based on the heating element's specifications), the control device controls the power supply module to output the corresponding operating current to the heating element corresponding to each heating zone, ensuring that the heating power in each heating zone reaches the target heating power, thereby maintaining the temperature of the multiple materials within the preset temperature range as they travel along the feed channel from the feed port to the discharge port. Thus, through the above arrangement, during the conveying of multiple different materials to be processed, the feeder of the present application can, based on the heating control method of the feeder of the present application, adaptively perform zoned heating according to the temperature of the materials to be processed in different heating zones and the location of the heating zones, thereby maintaining the temperature of each material to be processed within a preset temperature range during the process of conveying the material from the feed port to the discharge port. Compared to the overall heating method in the prior art, the accuracy and adaptability of the temperature control of the materials to be processed are improved during the feeding process of multiple materials to be processed.

[0030] In addition, it is understandable that in actual situations, the time for discharging the material from the heating furnace is different in different situations, and the time for processing the material to be processed after feeding is different in different situations. Therefore, in order to adapt to the actions of the heating furnace and the subsequent processing of the material to be processed, the control device in the feeding machine of the present application can also adjust the working parameters of the driving component based on the user's setting requirements, such as adjusting the frequency of the driving current output to the motor, so as to change the moving speed of the material tray driven by the driving component on the feeding channel. Therefore, in one embodiment of the present application, reference Figure 3 The step of controlling the heating components of each heating zone to operate according to the corresponding target heating power also includes: Step S310: Acquire the moving speed of the unloading tray in a moving state, and determine a corresponding first power adjustment value based on the moving speed; wherein the moving speed and the first power adjustment value are positively correlated; Step S320: reducing the current target heating power corresponding to each heating zone by the first power adjustment value and updating the target heating power, and controlling the heating components of each heating zone to operate according to the corresponding updated target heating power.

[0031] In this embodiment, the control device can determine the moving speed of the material discharging tray based on the moving speed of the material discharging tray determined by the above process or the speed detection sensor set on the material 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. The current target heating power corresponding to each heating zone is reduced by the first power adjustment value and updated, and the heating components of each heating zone are controlled to operate according to the corresponding 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 feed port to the discharge port, that is, the heat loss during the transmission process will become smaller, so the control device can appropriately reduce the current target heating power to achieve the purpose of energy saving. Of course, it is understandable that for the heating control method of the feeding machine of the present application, whether in the energy-saving control process in the above embodiment or the following embodiment, if the temperature of any material to be processed is close to the lower limit value of the preset temperature range, for example, the difference between them is less than the dangerous difference (preset by the R&D personnel), the control device will control the corresponding heating component to restore to the target heating power determined in step S200 to ensure that the temperature of the multiple materials to be processed remains within the preset temperature range during the process of moving from the feeding port to the discharge port along the feeding channel.

[0032] It should be understood that the distance between the multiple materials to be processed on the same material tray is generally relatively close. In other words, the heat between the adjacent materials to be processed will also be transferred to each other. Figure 4In one embodiment of the present application, the step of controlling the heating components of each heating zone to operate according to the corresponding target heating power further includes: Step S330: If the temperature of any material to be processed is within the preset temperature range and the temperature of the adjacent material to be processed is higher than its own temperature and the difference between the adjacent material to be processed and its own temperature is greater than the preset temperature difference, then the material to be processed is set as the first material to be processed; Step S340: controlling the current target heating power of the heating zone where the first material to be processed is located to be reduced by the second power adjustment value and updated, and controlling the heating components of the heating zone where the first material to be processed is located to operate according to the corresponding updated target heating power.

[0033] In this embodiment, the control device detects the temperature of each material during transport based on the aforementioned temperature detection process. If the temperature of a material is within a predetermined temperature range and the temperatures of its adjacent materials are both higher than its own, and the difference between either temperature and the material in the middle is greater than a predetermined temperature difference (set by the developer), for example, if the temperatures of the materials on either side of a material are both higher than its own within the same heating zone, and the difference between the temperatures of either material and the temperature of the material in the middle is greater than the predetermined temperature difference, or if the temperatures of the adjacent materials on either side of a material are both higher than its own within two adjacent heating zones, and the difference between the temperatures of either material and the temperature of the material in the middle is greater than the predetermined temperature difference, the control device will designate that material as the first material and deem the temperature difference between the first material and the adjacent materials to be processed to be greater than a predetermined temperature difference. The control device may then consider allowing the adjacent materials to provide more heat to the lower-temperature material in the middle, thereby reducing the heat provided by the heating assembly and achieving energy conservation. At this point, the control device controls the current target heating power of the heating zone containing the first material to be processed to be reduced by the second power adjustment value (pre-set by R&D personnel) and updated. It then adjusts the operating current of the heating components in the heating zone containing the first material to be processed so that they operate at the corresponding updated target heating power. In this way, since the temperatures of the materials on both sides of the material are relatively high and within the preset temperature range, and since, as can be seen above, the target heating power is set based on the lowest temperature of the materials in each heating zone when the unloading tray is initially moved (i.e., for other materials with higher temperatures, this target heating power is relatively sufficient to maintain their temperature), the higher-temperature material can provide a certain amount of heat to the lower-temperature material over a certain period of time. In other words, in this situation, the corresponding heating components can reduce the amount of heat they provide. In other words, the control device reduces the operating power of the heating components in this situation, thereby achieving energy savings.

[0034] In addition, in order to prevent the temperature of the material to be processed from being too low due to power reduction and thus falling below the preset temperature range, refer to Figure 5 In one embodiment of the present application, between step S330 and step S340, the step of controlling the heating components of each heating zone to operate according to the corresponding target heating power further includes: Step S350: obtaining the travel distance of the unloading tray on the feeding channel; Step S360: If the moved stroke does not reach half of the stroke of the feeding channel, step S340 is not executed; Step S370: When the moving stroke reaches half of the stroke of the feeding channel, if at least two first materials to be processed are placed in the same discharge area or first materials to be processed are placed in adjacent discharge areas, then step S340 is not executed; Step S380: When the moved stroke reaches half of the stroke of the feeding channel, if the first material to be processed is placed in the same discharge area and there is no situation where the first material to be processed is placed in both adjacent discharge areas, execute step 340.

[0035] In this embodiment, the control device first determines the travel distance of the current unloading tray. This travel distance can be achieved by positioning a contact sensor, such as an infrared reflection sensor, a grating sensor, or a trigger switch, at a position halfway along the feed channel. During the process of the unloading tray being transported from the discharge port to the feed port, if the contact sensor is triggered, the control device determines that the travel distance of the current unloading tray has reached halfway along the feed channel. At this time, if at least two first materials to be processed are placed in the same unloading zone (in which case the control device will determine that too many first materials to be processed will cause the temperature of other materials to be processed in the heating zone to drop too quickly, posing a certain risk) or if first materials to be processed are placed in adjacent unloading zones (in which case the control device will determine that simultaneously decreasing the target heating power of adjacent heating zones will pose a risk of a rapid temperature drop of the materials to be processed therein), step S340 is not executed. If the travel distance reaches halfway along the feed channel, if there is one first material to be processed in the same unloading zone, and if there are no adjacent unloading zones containing first materials to be processed, step S340 is executed. At the same time, if the contact sensor is not triggered, the control device will confirm that the current movement of the unloading tray has not reached half of the travel of the feeding channel, and the above step S340 will not be executed. In this way, through the above setting, the feeding machine of the present application can achieve a good balance between energy saving and ensuring the temperature of the material to be processed.

[0036] It should be understood that for some materials to be processed, especially those made of active metals or those requiring high precision and high purity, the materials may react with air during the feeding process, resulting in a decrease in quality. To this end, in one embodiment of the present application, an air inlet and an air outlet are further provided on the shell, the air inlet and the feeding port are provided on the same side, the air outlet is provided on the upper side of the shell, and the feeding machine further has an air supply module connected to the air inlet; The heating control method of the feeding machine also includes: Step S400: When the material tray moves the plurality of materials to be processed thereon from the material feeding port to the material discharging port via the driving assembly along the material feeding channel, the air supply module is controlled to input inert gas through the air inlet.

[0037] In this embodiment, when the material being processed, transported by the unloading tray, requires protection from an inert gas, the control device can control the operation of an air supply module, such as a fan and an inert gas storage bottle, while the unloading tray moves along the feed channel, so that an inert gas, such as argon, is introduced through the air inlet. Because argon has a greater density than air, it is deposited in the lower layer of the housing and some air is transported out of the housing through the air outlet. As a result, the material being processed on the unloading tray is enveloped in argon gas during transport, thereby protecting the material from contact with air.

[0038] Furthermore, it is understandable that, since the feed port and the air inlet are on the same side, the material to be processed placed in the first heating zone on the unloading tray will directly contact the inert gas blown out of the air inlet, and the contact area is large, so the temperature may drop faster than before. To this end, in one embodiment of the present application, the step of controlling the heating components of each heating zone to operate according to the corresponding target heating power also includes: Step S390: increasing the current target heating power of the first heating zone by the third power adjustment value and updating the target power, and controlling the heating component corresponding to the first heating zone to operate according to the updated target heating power.

[0039] In this embodiment, the developer can preset a third power adjustment value in advance. When the air supply module begins to supply inert gas under the control of the control device, the control device will increase the current target heating power of the first heating zone by the third power adjustment value and update it. For example, if the current target heating power corresponding to the first heating zone is αkW and the third power adjustment value is akW, the control device will use (α+a)kW as the new target heating power and then adjust the operating current of the heating module according to the new target heating power based on the process of the above embodiment, thereby controlling the heating component corresponding to the first heating zone to operate according to the updated target heating power. It is understood that the third power adjustment value can be obtained by the developer through multiple experiments during the development process so that after the third power adjustment value is increased, the temperature of the material to be heated in the current first heating zone can be maintained within the preset temperature range during the process of moving along the feeding channel from the feeding port to the discharging port.
