Description

Technical Field

[0001] This invention relates to the field of mixing machines, and more particularly to a control method for a mixing machine and a mixing machine. Background Technology

[0002] A mixer is a device used to uniformly mix materials of different components. By rotating the container, the materials flow within the container, and materials in different parts exchange positions to achieve mixing.

[0003] Traditional mixers typically consist of a cylinder and a motor that drives the cylinder to rotate. When material is poured into the cylinder, the motor drives the cylinder to rotate. Because the central axis of the cylinder in a traditional mixer is coaxial with the central axis of the motor's output shaft, the cylinder rotates around its central axis during rotation.

[0004] When the above-mentioned mixer is running, the material in the barrel will tumble and mix around the central axis of the barrel, but the material at both ends of the barrel cannot be exchanged and mixed, resulting in uneven mixing, which needs to be improved. Summary of the Invention

[0005] In order to make the mixing machine mix materials more evenly, the present invention provides a control method for the mixing machine and the mixing machine.

[0006] In a first aspect, the present invention provides a control method for a mixer, which adopts the following technical solution: A method for controlling a mixer, comprising: The material cylinder is controlled to rotate at a preset reference rotation speed, and the weight distribution information of the material along the axial direction inside the material cylinder is collected. Based on the weight distribution information, the weight concentration end and weight dispersion end of the material in the barrel are determined; Based on the weight distribution information, the position with the fewest gaps in the material distribution along the axial direction inside the barrel is determined. The apportionment distance is determined based on the weight concentration end and the vacancy position; The process of rotating the material cylinder once is divided into two stages, which include a first stage and a second stage. The first stage corresponds to the process of lifting one end of the material cylinder, and the second stage corresponds to the process of lifting the other end of the material cylinder. The stage type is matched based on the weight concentration end, and the stage rotation speed is matched based on the distribution distance, wherein the stage rotation speed is greater than the reference rotation speed. The material cylinder is controlled to rotate at the stage rotation speed of the corresponding stage type to distribute the material at the weight concentration end to the empty position, while the other stage type rotates at the reference rotation speed.

[0007] By adopting the above technical solution, when the barrel rotates, the weight distribution of the material inside the barrel is collected to determine the end where the material is concentrated. The rotation speed of the barrel is changed during the process of lifting the end where the material is concentrated in the barrel, so that the concentrated material can be distributed to the position where there is less material in the barrel.

[0008] Secondly, the present invention provides a mixing machine, which adopts the following technical solution: A mixing machine includes a support base, a material cylinder rotatably mounted on the support base, and a drive motor mounted on the support base for driving the material cylinder to rotate; the side wall of the material cylinder has symmetrically opened inlet and outlet; the central axis of the material cylinder has an eccentric angle with the rotation axis; when the outlet is perpendicular to the ground, the plane formed by the central axis of the material cylinder and the rotation axis is parallel to the ground to keep the material cylinder in a horizontal state.

[0009] By adopting the above technical solution, there is an eccentric angle between the central axis of the material cylinder and the rotation axis. When the drive motor drives the material cylinder to rotate, the material cylinder can not only rotate with the output shaft of the drive motor as the rotation axis, but also the two ends of the material cylinder can swing up and down, so that the materials at both ends of the material cylinder can be exchanged and mixed relatively, thereby making the materials in the entire material cylinder uniformly mixed; and when discharging, the material cylinder is in a horizontal state, and the materials are not easy to get stuck at both ends of the material cylinder, thus facilitating the discharge of materials.

[0010] Optionally, the material cylinder has an extended neck at the discharge port, and a sealing cap is hinged to the extended neck.

[0011] By adopting the above technical solution, the barrel is extended to form an extended neck, and a sealing cover is installed on the extended neck, which is more convenient and allows for more space to install various sensors.

[0012] Optionally, an auxiliary stirring mechanism is rotatably provided inside the material cylinder; the auxiliary stirring mechanism includes a stirrer, a connecting shaft rotatably mounted on the material cylinder, and a swing assembly that drives the stirrer to swing, the connecting shaft being used for mounting the stirrer and driving the stirrer to swing inside the material cylinder.

[0013] By adopting the above technical solution, when the barrel rotates, the auxiliary stirring mechanism can swing inside the barrel, and the stirrer can assist in stirring the material inside the barrel, promoting the exchange and mixing of materials, making the material mixture more uniform; and if there are lumps in the material, the stirrer can assist in breaking them up.

[0014] Optionally, the swing assembly includes a rotating plate connected to the end of the connecting shaft and a limiting plate locked to the material cylinder by an electric pin and rotating relative to the rotating plate; the limiting plate has two symmetrical limiting grooves; the rotating plate has a sliding groove along the radial direction, a sliding column is slidably installed in the sliding groove and a pressure spring is fixedly installed to drive the sliding column to move away from the connecting shaft and engage with the limiting groove; the limiting groove has guide parts on both sides to guide the sliding column to engage.

[0015] By adopting the above technical solution, when the barrel rotates, the agitator can be lifted to a certain height along with the barrel. Under the action of gravity of the agitator, the sliding column slides out from the limiting groove. At this time, the agitator can swing downward to impact and stir the material at the bottom of the barrel, thereby fully stirring the material. After the agitator swings downward, the sliding column can be inserted into another symmetrical limiting groove, causing the agitator to be lifted again, thus causing the agitator to swing in a cycle and continuously stir the material, making the material more evenly mixed.

[0016] Optionally, the agitator includes an arc-shaped plate and a stirring rod spaced apart from the arc-shaped plate and used to connect the arc-shaped plate and the connecting shaft; the area of ​​the arc-shaped plate is larger than the area of ​​the discharge port and the area of ​​the inlet; the two limiting grooves correspond to the discharge port and the inlet respectively, and when the sliding column is located in the limiting groove, the arc-shaped plate covers the inlet or the discharge port.

[0017] By adopting the above technical solution, when the sliding column is in the limiting groove, the arc plate can just cover the inlet or outlet, so that the material is not easily stuck in the space of the inlet or outlet during the rotation and stirring of the material cylinder, so that all materials can be fully mixed.

[0018] Optionally, the limiting plate has an arc-shaped groove, and the arc-shaped groove has a gear part; the material cylinder is provided with an open motor, and when the electric pin is unlocked, the open motor meshes with the gear part and drives the limiting plate to rotate so as to move the arc-shaped plate away from the discharge port.

[0019] By adopting the above technical solution, when material needs to be discharged, the limiting plate is first unlocked by the electric latch, and then the limiting plate is rotated by the open motor. At this time, the agitator can be raised a certain distance with the rotation of the limiting plate, thereby misaligning with the discharge port, so that the material can be discharged. The operation is relatively convenient.

[0020] Optionally, the cross-section of the stirring rod is rhomboid, with a dividing section for separating the condensed material; the surface of the arc-shaped plate is provided with convex strips at intervals to scoop up the material onto the stirring rod when the agitator swings.

[0021] By adopting the above technical solution, when the agitator stirs the material in the barrel, the convex strips can lift the material to the stirring rod, and the dividing part of the stirring rod can divide the material, so that the agglomerated blocks in the material can be broken up, thereby making the material uniformly mixed.

[0022] Optionally, the agitator includes multiple agitation units to facilitate installation of the agitator into the material cylinder; the side wall of the arc-shaped plate is provided with multiple connection holes, and a connecting rod is slidably installed in the connection holes to connect the multiple agitation units and to assist in agitating the material in the material cylinder.

[0023] By adopting the above technical solution, the agitator is divided into multiple agitation units, thereby reducing its volume and allowing the agitator to enter the material cylinder in batches, preventing it from getting stuck due to its large size. Furthermore, the agitation units are positioned and connected by connecting rods, enabling all agitation units to swing synchronously, resulting in even force distribution on the connecting shaft and reducing the risk of damage. Moreover, when the connecting rod is within the connecting hole, it can reciprocate within the connecting hole towards both ends of the material cylinder as the cylinder swings up and down; the extended connecting rod can be used for synchronous agitation of the material.

[0024] Optionally, the connecting shaft includes an intermediate shaft and end shafts respectively connected to both ends of the intermediate shaft and connected to the rotating plate; the intermediate shaft has an installation groove for sliding the stirrer, the installation groove passing through both end faces of the intermediate shaft; the end face of the end shaft has a limiting block that engages with the installation groove; the end shaft is rotatably provided with a connecting sleeve connecting the end shaft and the intermediate shaft.

[0025] By adopting the above technical solution, when installing the auxiliary mixing mechanism, the limiting plate, rotating plate and end shaft are first installed at both ends of the material cylinder, then the agitator is installed on the intermediate shaft, and finally the intermediate shaft is connected between the two end shafts; by installing the connecting shaft in sections, the installation process is made more convenient.

[0026] In summary, this application includes at least one of the following beneficial technical effects: When the barrel rotates, the weight distribution of the material inside the barrel is collected to determine the end where the material is concentrated. The rotation speed of the barrel is changed as the end where the material is concentrated is lifted upwards, so that the concentrated material can be distributed to the part of the barrel where there is less material. When the drum rotates, the agitator can be lifted to a certain height along with the drum. Under the action of gravity of the agitator, the sliding column slides out from the limiting groove. At this time, the agitator can swing downward to impact and stir the material at the bottom of the drum, thus fully stirring the material. After the agitator swings downward, the sliding column can be inserted into another symmetrical limiting groove, causing the agitator to be lifted again, thus making the agitator swing in a cycle and continuously stir the material, making the material more evenly mixed. When the sliding column is in the limiting groove, the arc plate can just cover the inlet or outlet, so that the material is not easily stuck in the space of the inlet or outlet during the rotation and stirring of the barrel, so that all the materials can be fully mixed.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] This application provides a mixing machine.

[0031] Reference Figure 1 and Figure 2 A mixing machine includes a support base 1, a material cylinder 2, a drive motor 3, and an auxiliary mixing mechanism 4. The support base 1 is fixed to the ground, and the control system of the mixing machine is mounted on the support base 1. The material cylinder 2 and the drive motor 3 are both mounted on the support base 1, and the drive motor 3 is connected to the material cylinder 2 to drive the material cylinder 2 to rotate. The auxiliary mixing mechanism 4 is installed inside the material cylinder 2 to assist in mixing the material inside the material cylinder 2.

[0032] The material cylinder 2 is a rotating body, with an inlet 21 and an outlet 22 symmetrically located on opposite sides of the cylinder 2. The outlet 22 has an extended neck 23 perpendicular to the side wall of the cylinder 2, and a sealing cap 24 is hinged to the extended neck 23 to seal the outlet 22. In this embodiment, the structure of the inlet 21 is the same as that of the outlet 22, and will not be described further.

[0033] In this embodiment, when the material cylinder 2 is installed on the support base 1, there is an eccentric angle of 25 between its central axis and the rotation axis. The material cylinder 2 rotates about the rotation axis, and the output shaft of the drive motor 3 is coaxial with the rotation axis. When the drive motor 3 drives the material cylinder 2 to rotate, the material cylinder 2 can not only rotate horizontally about the rotation axis, but both ends of the material cylinder 2 can also swing up and down.

[0034] In order to prevent the material from getting stuck at both ends of the material cylinder 2 during discharge, when the discharge port 22 is perpendicular to the ground, the plane formed by the central axis and the rotation axis of the material cylinder 2 is parallel to the ground, that is, the material cylinder 2 is in a horizontal state.

[0035] Reference Figure 2 and Figure 3 The auxiliary stirring mechanism 4 includes a stirrer 41, a connecting shaft 42, and a swing assembly 43. The connecting shaft 42 is coaxial with the central axis of the material cylinder 2, and its two ends are rotatably mounted on both ends of the inner cavity of the material cylinder 2. The stirrer 41 is mounted on the connecting shaft 42 and can rotate with the rotation of the connecting shaft 42. The swing assembly 43 is located at both ends of the connecting shaft 42 and is used to drive the stirrer 41 to swing back and forth when the material cylinder 2 rotates to assist in stirring the material inside the material cylinder 2.

[0036] Reference Figure 4The connecting shaft 42 includes an intermediate shaft 421 and two end shafts 422. There are two end shafts 422, each connected to one end of the intermediate shaft 421. The intermediate shaft 421 has a mounting groove 423 extending along its length and passing through it. The end faces of the end shafts 422 facing the intermediate shaft 421 have limiting blocks 424. When the end shafts 422 are connected to the intermediate shaft 421, the limiting blocks 424 can be radially engaged with both ends of the mounting grooves 423. To reinforce the intermediate shaft 421 and end shafts 422, a connecting sleeve 425 is rotatably mounted on the end shafts 422. When the intermediate shaft 421 and end shafts 422 are connected, rotating the connecting sleeve 425 allows it to be threadedly connected to both the intermediate shaft 421 and the end shafts 422 (the threads are not shown in the figure).

[0037] Reference Figure 2 and Figure 5 The agitator 41 includes an agitator rod 411 and an arc plate 412. The outer arc surface of the arc plate 412 is in contact with the inner wall of the barrel 2. When the agitator 41 swings inside the barrel 2, the arc plate 412 can slide relative to the inner wall of the barrel 2.

[0038] Reference Figure 4 and Figure 5 There are multiple stirring rods 411, which are fixedly connected to the inner arc surface of the arc plate 412 and are spaced apart along the length of the arc plate 412. The end of the stirring rod 411 away from the arc plate 412 is slidably installed in the mounting groove 423 of the intermediate shaft 421, and is clamped and fixed from both ends by the limiting block 424 of the end shaft 422 when the end shaft 422 is connected to the intermediate shaft 421.

[0039] In this embodiment, the stirring rod 411 has a rhomboid cross-section and a segmented portion 4111. The surface of the arc-shaped plate 412 has protrusions 413 along its length, and these protrusions 413 are spaced apart along the circumference of the arc-shaped plate 412. When the stirrer 41 oscillates, the protrusions 413 of the arc-shaped plate 412 can scoop up the material, which is then lifted to the stirring rod 411. The segmented portion 4111 of the stirring rod 411 can divide the material and allow it to pass between adjacent stirring rods 411. If the material contains agglomerated lumps, these lumps can be broken up by the segmented portion 4111, thereby ensuring uniform mixing of the material.

[0040] Reference Figure 2 and Figure 5 In this embodiment, the area of ​​the arc plate 412 of the agitator 41 is larger than the area of ​​the feed inlet 21 and the area of ​​the discharge outlet 22. In order to facilitate the installation of the agitator 41 into the material cylinder 2, the agitator 41 includes multiple agitation units 414. Each agitation unit 414 includes an agitation rod 411 and an arc plate 412. Therefore, the volume of each agitation unit 414 is relatively small.

[0041] Furthermore, the arc-shaped plate 412 has multiple connecting holes 415 extending along its length. A connecting rod 416 slides telescopically within each connecting hole 415. The length of the connecting rod 416 is greater than the width of the arc-shaped plate 412, allowing the connecting rod 416 to pass through all the arc-shaped plates 412. When the agitator 41 oscillates within the barrel 2, the connecting rod 416 reciprocates within the connecting holes 415 as the two ends of the barrel 2 move up and down. The portion of the connecting rod 416 extending out of the agitator 41 also agitates the material within the barrel 2.

[0042] Reference Figure 2 and Figure 6 The swing assembly 43 includes a limiting plate 431, a rotating plate 432, a sliding column 433, and a pressure spring 434. The limiting plate 431 is rotatably mounted on both ends of the material cylinder 2. The material cylinder 2 is provided with an electric pin 435, which is inserted into the limiting plate 431, thereby fixing the limiting plate 431 to the material cylinder 2. The rotating plate 432 is integrally connected to both ends of the connecting shaft 42 and can rotate relative to the limiting plate 431.

[0043] A sliding groove 4321 is provided radially on the rotating plate 432. The sliding column 433 slides in the sliding groove 4321. The pressure spring 434 extends and retracts in the sliding groove 4321. The pressure spring 434 abuts against the sliding column 433. The pressure spring 434 drives the sliding column 433 to always have a tendency to move away from the connecting shaft 42.

[0044] The limiting plate 431 is annular, and its inner wall has a limiting groove 4311 for the sliding column 433 to be inserted into. There are two limiting grooves 4311, which are symmetrically arranged. There are guide parts 4312 on both sides of the limiting groove 4311.

[0045] When the swing assembly 43 is installed inside the barrel 2, the sliding column 433 is always positioned within the limiting groove 4311 under the drive of the pressure spring 434. The guide part 4312 is used to guide the sliding column 433 into the limiting groove 4311.

[0046] When the barrel 2 rotates, the limiting plate 431 can rotate synchronously with the barrel 2. Since the sliding column 433 is stuck in the limiting groove 4311, the rotating plate 432 and the agitator 41 can rotate synchronously with the limiting plate 431. When the agitator 41 starts to rotate and rise from the bottom of the barrel 2, the torque on the rotating plate 432 gradually increases. When the agitator 41 is raised by 90° to 120°, the pressure spring 434 is compressed, and the sliding column 433 is dislodged from the limiting groove 4311. At this time, the agitator 41 swings downward under the action of gravity, and the swing direction of the agitator 41 is opposite to the rotation direction of the barrel 2.

[0047] As the stirrer 41 rotates downward, the pressure spring 434 applies pressure to the sliding column 433, which can then engage with another symmetrical limiting groove 4311. At this point, the rotating plate 432 and the limiting plate 431 are locked again, and the stirrer 41 begins to rise again, thus forming a oscillating cycle.

[0048] Reference Figure 2 and Figure 6 In this embodiment, the two limiting grooves 4311 of the limiting plate 431 correspond one-to-one with the feed inlet 21 and the discharge outlet 22 of the material cylinder 2. When the sliding column 433 is engaged in the limiting groove 4311, the arc-shaped plate 412 of the agitator 41 covers the feed inlet 21 or the discharge outlet 22. When the agitator 41 is oscillating, the arc-shaped plate 412 can circulate back and forth between the feed inlet 21 and the discharge outlet 22, always covering the feed inlet 21 and the discharge outlet 22, thereby preventing materials from falling into the feed inlet 21 or the discharge outlet 22 when the mixer is mixing.

[0049] The limiting plate 431 has an arc-shaped groove 4313 circumferentially, and a gear part 4314 is provided in the arc-shaped groove 4313. An open-end motor 436 is provided on the material cylinder 2. The open-end motor 436 is located outside the material cylinder 2, and its output shaft extends into the material cylinder 2 and is located in the arc-shaped groove 4313. The output shaft of the open-end motor 436 has a drive gear 437, which meshes with the gear part 4314.

[0050] The limiting plate 431 has two locking holes 4315. The electric pin 435 can be inserted into the locking holes 4315 to lock the limiting plate 431, so that the limiting plate 431 has a stirring state and a discharging state.

[0051] When the limiting plate 431 is in the stirring state, the arc plate 412 of the agitator 41 always covers the feed inlet 21.

[0052] When the limiting plate 431 is in the discharge state, the electric pin 435 exits from the locking hole 4315 and inserts into another locking hole 4315. The open motor 436 drives the limiting plate 431 to rotate. At this time, the rotating plate 432 and the agitator 41 can rotate with the limiting plate 431 at a certain angle, so that the arc plate 412 is misaligned with the discharge port 22.

[0053] Based on the same inventive concept, this application provides a control method for a mixing machine.

[0054] A method for controlling a mixer includes the following steps: Step S100: Control the material cylinder 2 to rotate at a preset reference rotation speed, and collect the weight distribution information of the material along the axial direction inside the material cylinder 2.

[0055] The reference rotation speed is the rotation speed of the material cylinder 2 when it mixes materials, as set by the technicians, and will not be elaborated here.

[0056] Weight distribution information refers to the distribution of material weight across different regions within the material cylinder 2. The inner wall of the material cylinder 2 is divided into multiple regions, each equipped with a pressure sensor. As the material cylinder 2 rotates, the pressure sensors collect the material weight at all locations along the axial direction at the bottom of the cylinder 2, and the weight distribution information is then synthesized.

[0057] Step S101: Based on the weight distribution information, analyze and determine the weight concentration end and weight dispersion end of the material in the material cylinder 2.

[0058] The material cylinder 2 has two ends. The weight of the material at the two ends of the material cylinder 2 is compared. The weight concentration end refers to the end of the material cylinder 2 with relatively more material, while the weight dispersion end refers to the end of the material cylinder 2 with relatively less material.

[0059] By analyzing the weight distribution information, the weight of the material at both ends of the material cylinder 2 can be determined. By comparing the weights at the two locations, the weight concentration end and the weight dispersion end can be identified.

[0060] Step S102: Based on the weight distribution information, determine the position with the least amount of empty space along the axial direction of the material in the material cylinder 2.

[0061] A vacant location refers to the position within the material cylinder 2 where the material distribution along the axial direction is minimal. By analyzing the weight distribution information, the weight values ​​of the material in all areas along the axial direction at the bottom of the material cylinder 2 are determined, and then compared to identify the vacant location.

[0062] Step S103: Determine the apportionment distance based on the weight concentration end and the vacancy position.

[0063] The weight distribution distance is the distance between the area where the weight concentration point is located and the area where the vacancy is located. Once both the weight concentration point and the vacancy are determined using weight distribution information, the distance between them can also be determined. The relative positions of each area within the barrel 2 are entered into the system; therefore, when the positions of two areas are determined, the distance between them can be directly determined.

[0064] In subsequent embodiments, the material in the area where the weight is concentrated needs to be distributed to the empty positions so that the material distribution in the material cylinder 2 is more uniform and can be mixed evenly.

[0065] Step S104: The process of rotating the material cylinder 2 one revolution is divided into two stages. The stage types include a first stage and a second stage. The first stage corresponds to the process of lifting one end of the material cylinder 2, and the second stage corresponds to the process of lifting the other end of the material cylinder 2.

[0066] In this embodiment, because there is an angle between the central axis and the rotation axis of the material cylinder 2, both ends of the material cylinder 2 can swing up and down when the material cylinder 2 rotates. During one revolution of the material cylinder 2, when one end of the material cylinder 2 rises, the other end falls.

[0067] Based on the above principle, the process of rotating the material cylinder 2 once is divided into two stages, namely the first stage and the second stage. The first stage corresponds to the process of lifting one end of the material cylinder 2, and the second stage corresponds to the process of lifting the other end of the material cylinder 2.

[0068] Step S105: Match the corresponding stage type based on the weight concentration end, and match the stage rotation speed based on the distribution distance, wherein the stage rotation speed is greater than the reference rotation speed.

[0069] In this embodiment, it is necessary to distribute the material at the weight concentration end to the empty position. This is achieved by rapidly lifting the weight concentration end of the material cylinder 2, thereby throwing the material at the weight concentration end up and letting it fall into the empty position.

[0070] Once the weight concentration end is determined, its position within the barrel 2 can be directly determined, thus enabling the determination of whether it is the first or second stage, i.e., which end of the barrel 2 needs to increase its speed during the lifting process.

[0071] The stage rotation speed refers to the rotation speed at which the end of the cylinder 2, where the weight concentration end is located, is lifted. The stage rotation speed is directly proportional to the distribution distance; the greater the distribution distance, the greater the stage rotation speed.

[0072] Step S106: Control the material cylinder 2 to rotate at the stage rotation speed of the corresponding stage type to distribute the material at the weight concentration end to the empty position, and the other stage type to rotate at the reference rotation speed.

[0073] After determining the stage type and stage rotation speed, the material cylinder 2 is controlled to rotate at the first stage or the second stage rotation speed, so that the material can be thrown up to the empty position during the upward lifting of the end where the weight is concentrated.

[0074] When the material poured into the material cylinder 2 has a certain degree of moisture, the treatment method includes the following steps: In this embodiment, the barrel has an inflation channel for inflating its interior. The inflation channel starts from the end face of the barrel 2, passes through the interior of the connecting shaft 42, the interior of the stirring rod 411, and the interior of the arc-shaped plate 412, and finally blows out from the surface of the arc-shaped plate 412, forming an air vortex in the circumferential direction inside the barrel 2. The air outlet on the surface of the arc-shaped plate 412 is a one-way air outlet, allowing only air to escape.

[0075] Step S200: Collect the moisture content of the material inside the material cylinder 2. The material humidity value refers to the humidity of the material poured into the material cylinder 2. The material cylinder 2 is equipped with a humidity sensor, which can detect the humidity of the material when it is poured into the material cylinder 2.

[0076] Step S201: Match the evaporation temperature based on the material humidity value.

[0077] Evaporation temperature refers to the temperature at which moisture on a material is evaporated, thus drying the material. Evaporation temperature is directly proportional to the moisture content of the material; the higher the moisture content, the higher the evaporation temperature.

[0078] Step S202: Based on the evaporation temperature, match the pressure value inside the cavity, and determine the inflation volume according to the pressure value inside the cavity and the preset reference pressure.

[0079] The internal pressure refers to the gas pressure inside the barrel 2. When the sealed space is pressurized with gas, the temperature inside the sealed space also increases as the pressure increases. Therefore, the internal pressure is directly proportional to the evaporation temperature; the higher the evaporation temperature, the higher the internal pressure.

[0080] The reference pressure refers to standard atmospheric pressure. When the barrel 2 is sealed and not yet filled with gas, the air pressure inside and outside the barrel 2 is balanced, both being the reference pressure.

[0081] The inflation volume refers to the amount of air required to increase the pressure inside the barrel 2 from the reference pressure to the internal pressure value. The inflation volume can be determined based on the internal pressure value, the reference pressure, and the preset internal volume of the barrel 2. The internal volume of the barrel 2 is a standard parameter and will not be elaborated here.

[0082] Step S203: Match the heat dissipation speed based on the preset barrel material, and match the inflation speed based on the heat dissipation speed.

[0083] The barrel material is based on the standard parameters for barrel 2, and will not be elaborated upon here. Heat dissipation rate refers to the rate at which temperature is lost through the barrel wall. The heat dissipation rate can be obtained from a pre-defined material heat dissipation table based on the barrel material. This material heat dissipation table is a data table compiled by technicians through experimental testing of objects made of different materials, and will not be elaborated upon here.

[0084] Inflation speed refers to the rate at which air is inflated into the barrel 2. Since the barrel 2 dissipates heat, a certain speed is required to inflate it. The inflation speed is directly proportional to the heat dissipation rate; the greater the heat dissipation rate, the greater the inflation speed.

[0085] Step S204: Inflate the material cylinder 2 with the inflation speed and the inflation amount. The inflated air forms a vortex in the material cylinder 2 to dry the material. Determine the temperature increment of the air in the material cylinder 2 according to the heat dissipation rate, and use the temperature increment to heat the air in the material cylinder 2.

[0086] The air-filling device pre-installed on the mixer is controlled to inflate the material cylinder 2 with air-filling speed and volume, so that the air pressure inside the material cylinder 2 reaches the cavity pressure value, and the temperature inside the material cylinder 2 reaches the evaporation temperature due to the pressurization, thereby drying the material.

[0087] The air temperature increment refers to the increase in temperature of the air introduced into the cylinder 2. When the temperature inside the cylinder 2 reaches the evaporation temperature, it is not necessary to further increase the pressure inside the cylinder 2. At this point, the air introduced into the cylinder needs to be heated to compensate for the heat dissipation rate of the cylinder 2, thus maintaining the evaporation temperature inside the cylinder 2. Therefore, the air temperature increment is directly proportional to the heat dissipation rate; the greater the heat dissipation rate, the greater the air temperature increment.
