Description

Technical Field

[0001] The invention relates to the technical field of heater production, in particular to a production device for a shovel-tooth type anti-condensation PTC heater. Background Art

[0002] With the development of modern industry, PTC heaters have been widely used in various fields, especially in applications requiring precise temperature control. Spade-tooth anti-condensation PTC heaters, as a special type of PTC heater, are particularly popular in applications requiring long-term stable operation and subject to large ambient temperature fluctuations due to their excellent anti-condensation performance and efficient heat conduction capabilities.

[0003] In the production equipment of traditional skived-tooth anti-condensation PTC heaters, the fin structure of the traditional PTC heater cannot be pressed in the middle when pressing the tube, and can only be pressed on both sides of the aluminum tube, resulting in poor fit in the middle of the aluminum tube and large power attenuation of the product; before scraping out the fins on the aluminum tube, a section of the middle of the aluminum tube is cut off. After the fins are scraped out, the tube pressing operation of the middle section of the fin is facilitated, which improves the problem of not being able to press the middle of the aluminum tube, can effectively reduce the power attenuation rate of the product and increase the product life.

[0004] Therefore, a skive-tooth type anti-condensation PTC heater production device is provided to solve the problems of single processing method and inadequate dust cleaning. Summary of the Invention

[0008] Two blowing devices are provided on both sides of the processing chamber, and the two blowing devices are symmetrical with respect to the axis of the processing chamber. The blowing devices are used to blow inert gas into the interior of the processing chamber.

[0009] The processing chamber is cylindrical, and an air inlet is opened on the outer wall of the processing chamber. A ventilation pipe is fixedly connected to the air inlet of the processing chamber. One end of the ventilation pipe is fixedly connected to the processing chamber, and the other end of the ventilation pipe is fixedly connected to the blowing device. When the blowing device is turned on, the blowing device blows gas into the interior of the processing chamber through the ventilation pipe.

[0010] The interior of the ventilation pipe is rotatably connected to an electric shaft sleeve, and the inner wall of the electric shaft sleeve is fixedly connected to a motor three, and the motor three includes a motor three main shaft, and the motor three main shaft is fixedly connected to the electric shaft sleeve.

[0011] By starting the electric sleeve, the electric sleeve rotates inside the ventilation pipe, and the electric sleeve drives the wind direction control member to rotate horizontally, thereby controlling the direction of the air blown out by the blowing device to the left or right; starting the motor three, the motor three drives the wind direction control member to rotate longitudinally, thereby controlling the direction of the air blown out by the blowing device to be upward or downward;

[0012] The inner wall of the processing chamber is fixedly connected to a blade, and the structure of the blade is a rectangular plate. The blade includes an upper surface and a lower surface. The middle of the upper surface of the blade is concave, and the middle of the lower surface of the blade is convex. A collection groove is opened on the upper surface of the blade. The collection groove is used to collect dust generated by the device during operation. The bottom surface of the collection groove is horizontal, and the inner wall of the collection groove is arc-shaped;

[0015] The yoke is provided with a plurality of support members, each of which is provided with a plurality of support members, each of which is provided with a plurality of support members, and the support members are provided with a plurality of support members.

[0016] The present invention further describes that the dust reduction device includes an atomizing nozzle, the atomizing nozzle passes through the processing chamber, and the atomizing nozzle is aligned with the inner wall of the processing chamber.

[0017] The present invention further illustrates that the sliding assembly includes a connecting block, which is fixedly connected to the two ends of the outer wall of the processing warehouse, and a connecting groove is provided on the contact surface of the connecting block and the processing warehouse, and a through hole is provided at the connection between the processing warehouse and the connecting groove. The inside of the connecting groove is fixedly connected to an electric guide rail, and a connecting rod 1 is slidably connected to the electric guide rail. One end of the connecting rod 1 is slidably connected to the electric guide rail, and the other end of the connecting rod 1 is fixedly connected to a sealing plate 1, and two fixing rods are fixedly connected to the two sealing plates 1, and the two ends of the fixing rod are fixedly connected to the two sealing plates 1. The milling cutter is slidably connected to the bottom of the fixing rod, and the milling cutter is driven to slide on the fixing rod by starting the fixing rod, and the milling cutter is used for processing aluminum tubes.

[0018] The present invention further describes that a spray device is fixed on the side of the windshield, the spray device and the milling cutter are in the same direction relative to the windshield, the spray device is used to spray anti-condensation agent, the spray device includes a nozzle, and the nozzle is directed toward the clamping device.

[0019] The present invention further illustrates that a material inlet is provided on the surface of the processing chamber, and a sealing door is slidably connected to the material inlet, and the sealing door is used to seal the internal space of the processing chamber.

[0020] A second aspect of the present invention provides a method for producing a skive-tooth type anti-condensation PTC heater production device, comprising: when the device processes an aluminum tube of the skive-tooth type heater, fixing the aluminum tube on the clamping device, at this time, the aluminum tube is directly below the milling cutter, starting the fixing rod, and the fixing rod drives the milling cutter to move toward one end of the aluminum tube; when the milling cutter moves to the top end of the aluminum tube, closing the fixing rod, starting the milling cutter and the electric guide rail, the electric guide rail drives the connecting rod 1, the sealing plate 1, and the fixing rod to move downward, and the fixing rod drives the milling cutter to move downward;

[0021] Assume that the depth of the groove to be cut on the aluminum tube surface is a, and the distance from the bottom end of the milling cutter to the surface of the aluminum tube is b. When the milling cutter moves downward a distance c=a+b, the electric guide rail stops, the fixed rod is activated, and the milling cutter moves toward the other end of the aluminum tube on the fixed rod. When the milling cutter leaves the aluminum tube from the other end, the milling cutter is closed, and the milling cutter is returned to its original position by activating the electric guide rail and the fixed rod. The processing of the aluminum tube is completed and sent to the next process.

[0022] When different shapes and sizes of slots for different aluminum tubes are required, the milling cutters of different models and structures can be replaced;

[0023] When processing aluminum tubes, aluminum chips and dust are inevitably generated. By starting one of the blowing devices to blow air into the interior of the processing chamber, the direction of the airflow blown out by the blowing device is turned obliquely downward by controlling the direction of the vent of the wind direction control component. When the airflow enters the interior of the processing chamber, it collides with the inner wall of the processing chamber. Since the processing chamber is cylindrical, the airflow inside the processing chamber is spiral downward. The airflow inside the processing chamber drives the dust generated during the processing of the aluminum tube to perform a downward circular motion in the processing chamber. Since the dust itself contains mass, centrifugal force is generated when the dust performs a circular motion. Under the action of the centrifugal force, the dust collides with the inner wall of the processing chamber. When the dust collides with the inner wall of the processing chamber, it slides down.

[0024] Furthermore, when the dust mass is small, the centrifugal force generated is insufficient to cause the dust itself to collide with the inner wall of the processing chamber. In this case, the dust will collide with the blade and slide down on its upper surface. When the dust falls into the collection trough, it will be collected. The small dust will accumulate in the collection trough to prevent it from floating back into the processing chamber during the downward sliding process.

[0025] By starting the motor 1, the motor 1 main shaft of the motor 1 drives the bevel gear to rotate, and the bevel gear drives the conical cylinder to rotate by meshing with the conical teeth. When the dust in the processing chamber falls onto the inner wall of the conical cylinder, the rotating dust passing through the conical cylinder is finally gathered inside the spiral groove and forms a dust flow that flows into the interior of the storage chamber.

[0026] By starting one of the fans, the fan blows the aluminum chips and dust generated when the aluminum tube is processed on the clamping device from the support plate to the inner wall of the processing chamber. The wind blown by the fan carries the aluminum chips and dust and hits the inner wall of the processing chamber and then rebounds to all sides. By controlling the direction of the vent of the wind direction control component, the air flow blown out by the blowing device is directed downward, and most of the aluminum chips and dust are blown to the collecting component, while a small part of the aluminum chips and dust floats inside the processing chamber.

[0027] Furthermore, when processing the dust floating in the processing chamber, the second motor is turned on, the second motor drives the second connecting rod to rotate, and the second connecting rod drives the sliding rod and the wind shield to rotate. When the wind shield rotates to be in the same straight line with the air outlets of the two fans, the second motor is stopped.

[0028] Simultaneously starting the two fans, after the airflows generated by the fans collide with the wind shield, the two airflows generated by the fans are directed upward by the wind shield and merge into one due to the inclined and inwardly concave top of the wind shield;

[0029] At the same time, the upward airflow and the downward airflow generated by the blowing device are convected inside the processing chamber, and the convected airflow spreads in all directions and further hits the inner wall of the processing chamber with dust;

[0030] When the airflow inside the processing chamber collides with the inner wall, a small amount of dust will move upward and adhere to the inner wall of the processing chamber. By turning on the dust reduction device, the atomizing nozzle sprays mist toward the inner wall of the processing chamber and forms small water droplets that slide down into the collecting component with the dust. During the sliding process, the small water droplets further clean the aluminum chips and dust inside the conical cylinder, and the collection of aluminum chips and dust is completed.

[0031] Compared with the prior art, the present invention has the following beneficial effects: by providing an air blowing device and an air direction control member, the present invention can accurately control the flow direction of the gas in the processing chamber, thereby effectively carrying the dust and aluminum chips generated during the processing to the inner wall of the processing chamber, facilitating subsequent collection and treatment;

[0032] The structure of the conical barrel and spiral groove allows the fallen dust and aluminum chips to flow smoothly to the storage bin, avoiding secondary pollution;

[0033] Blowing in inert gas helps reduce oxidation reactions during processing and improve product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0050] See also Figure 1 — Figure 10 The present invention provides a technical solution: a skived-tooth anti-condensation PTC heater production device, comprising a processing chamber 1 and a sliding component 5.

[0051] like Figure 1 As shown, in some embodiments, a collecting assembly 2 is fixedly connected below the processing bin 1, and a storage bin 3 is fixedly connected below the collecting assembly 2. The storage bin 3 is used to collect dust and aluminum chips generated during material processing.

[0052] Two blowing devices 6 are provided on both sides of the processing chamber 1. The two blowing devices 6 are symmetrical with respect to the axis of the processing chamber 1. The blowing devices 6 are used to blow inert gas into the interior of the processing chamber 1. The top of the outer wall of the processing chamber 1 is fixedly connected to a dust reduction device 9. The dust reduction device 9 is used to make the dust in the processing chamber 1 fall. The top of the processing chamber 1 is fixedly connected to a sealing plate 7. An exhaust pipe 8 is fixed above the sealing plate 7. The exhaust pipe 8 is used to discharge the gas inside the processing chamber 1.

[0053] like Figure 2 As shown, in some embodiments, the processing chamber 1 is cylindrical, and an air inlet is opened on the outer wall of the processing chamber 1. A ventilation pipe 101 is fixedly connected to the air inlet of the processing chamber 1. One end of the ventilation pipe 101 is fixedly connected to the processing chamber 1, and the other end of the ventilation pipe 101 is fixedly connected to the blowing device 6. By turning on the blowing device 6, the blowing device 6 blows gas into the interior of the processing chamber 1 through the ventilation pipe 101.

[0054] like Figure 3 and Figure 4 As shown, in some embodiments, the interior of the ventilation pipe 101 is rotatably connected to an electric shaft sleeve 104, and the inner wall of the electric shaft sleeve 104 is fixedly connected to a motor three 106, and the motor three 106 includes a motor three main shaft, and the motor three main shaft is fixedly connected to the electric shaft sleeve 104, and a wind direction control component 105 is fixedly connected to the motor three 106, and the wind direction control component 105 is penetrated by the motor three main shaft. The wind direction control component 105 is a spherical shell structure, and the motor three 106 is fixedly connected to the inner wall of the wind direction control component 105. Two ventilation holes are provided on the surface of the wind direction control component 105, and the ventilation holes of the wind direction control component 105 are symmetrical with respect to the plane passing through the center of the sphere, and the ventilation holes are used for the passage of airflow.

[0055] By starting the electric sleeve 104, the electric sleeve 104 rotates inside the ventilation pipe 101, and the electric sleeve 104 drives the wind direction control member 105 to rotate horizontally, controlling the direction of the gas blown out by the blowing device 6 to the left or right, and starting the motor three 106, the motor three 106 drives the wind direction control member 105 to rotate longitudinally, controlling the direction of the gas blown out by the blowing device 6 to be upward or downward.

[0056] like Figure 2 and Figure 5 As shown, in some embodiments, a blade 102 is fixedly connected to the inner wall of the processing chamber 1. The structure of the blade 102 is a rectangular plate. The blade 102 includes an upper surface and a lower surface. The middle of the upper surface of the blade 102 is concave, and the middle of the lower surface of the blade 102 is convex. A collection groove 103 is provided on the upper surface of the blade 102. The collection groove 103 is used to collect dust generated by the device during operation. The bottom surface of the collection groove 103 is horizontal, and the inner wall of the collection groove 103 is arc-shaped.

[0057] The middle of one side of the blade 102 is concave, and the middle of the other side of the blade 102 is convex. The convex side of the blade 102 is in contact with the inner wall of the processing chamber 1, and the bottom of the blade 102 is in the same horizontal plane as the bottom of the processing chamber 1.

[0058] When the device processes the aluminum tube of the shovel-tooth heater, air is blown into the interior of the processing chamber 1 through one of the blowing devices 6. When the air flow enters the interior of the processing chamber 1, it collides with the inner wall of the processing chamber 1. Since the processing chamber 1 is cylindrical, the air flow inside the processing chamber 1 is spiral downward. The air flow inside the processing chamber 1 drives the dust generated during the processing of the aluminum tube to perform a downward circular motion in the processing chamber 1. Since the dust itself contains mass, centrifugal force is generated when the dust performs a circular motion. Most of the dust collides with the inner wall of the processing chamber 1 under the action of centrifugal force. When the dust collides with the inner wall of the processing chamber 1, it will slide down.

[0059] When the dust mass is small, the centrifugal force generated is not enough to make the dust itself hit the inner wall of the processing chamber 1. At this time, the dust hits the blade 102 and slides down on its upper surface. When the dust falls into the collection trough 103, it is collected and the small dust accumulates inside the collection trough 103.

[0060] like Figure 6 and Figure 7 As shown, in some embodiments, the collecting assembly 2 includes a support frame 201, the upper part of the support frame 201 is fixedly connected to the processing bin 1, and the lower part of the support frame 201 is fixedly connected to the storage bin 3, the support frame 201 includes a top plate, a through hole is provided in the center of the top plate of the support frame 201, a conical cylinder 202 is slidably connected to the through hole of the top plate, and two spiral grooves 206 are provided on the inner wall of the conical cylinder 202, one end of the spiral groove 206 is flush with the top of the conical cylinder 202, and the other end of the spiral groove 206 is flush with the bottom of the conical cylinder 202, and the two spiral grooves 206 are axially symmetrical with respect to the symmetry axis of the longitudinal section of the conical cylinder 202. The outer arm of the conical cylinder 202 is provided with conical teeth 203, and the conical teeth 203 are meshed and connected with a conical gear 204. The conical gear 204 is fixedly connected to a motor 1 205. The motor 1 205 includes a motor shaft, which is fixedly connected to the conical gear 204. The motor 1 205 is fixedly connected to the inner wall of the support frame 201.

[0061] By starting motor 1 205, the motor 1 main shaft of motor 1 205 drives the bevel gear 204 to rotate, and the bevel gear 204 drives the conical cylinder 202 to rotate through the meshing connection with the conical teeth 203. When the dust in the processing chamber 1 falls to the inner wall of the conical cylinder 202, the rotating dust passing through the conical cylinder 202 is finally gathered inside the spiral groove 206 and forms a dust flow that flows to the inside of the storage chamber 3.

[0062] like Figure 2 and Figure 8 As shown, in some embodiments, a support plate 10 is fixedly connected to the bottom of the inner wall of the processing chamber 1, and a clamping device 11 is fixed above the support plate 10. The clamping device 11 is at the center of the cross section of the processing chamber 1. The clamping device 11 is used to clamp the processed aluminum tube. The two ends above the support plate 10 are fixedly connected to a fan 13, and the fan 13 includes an air outlet. The air outlet of the fan 13 is facing the direction of the clamping device 11. Two wind shields 12 are provided above the support plate 10. The two wind shields 12 are symmetrical with respect to the center of the clamping device 11, and the wind shield 12 is an arc-shaped structure as a whole. Structure, the top of the windshield 12 is inclined toward the clamping device 11, and a sliding rod 14 is fixedly connected to the bottom of the two windshields 12. The sliding rod 14 passes through the support plate 10. A sliding groove 17 is provided at the connection between the support plate 10 and the sliding rod 14. The sliding rod 14 slides in the sliding groove 17. The bottom of the two sliding rods 14 is fixedly connected to the same connecting rod 2 15, and the middle part of the connecting rod 2 15 is fixedly connected to the motor 2 16. The motor 2 16 includes a motor second main shaft, and the motor second main shaft is fixedly connected to the connecting rod 2 15. The motor 2 16 is fixedly connected to the bottom of the support plate 10.

[0063] By starting one of the fans 13, the fan 13 blows air to blow the iron filings and dust generated when processing the aluminum tube on the clamping device 11 off the support plate 10 and drop them into the collection assembly 2. When processing the dust floating in the processing chamber 1, by turning on the motor 2 16, the motor 2 16 drives the connecting rod 2 15 to rotate, and the connecting rod 2 15 drives the sliding rod 14 and the wind shield 12 to rotate. When the wind shield 12 rotates to the same straight line as the air outlet of the two fans 13, the motor 2 16 stops.

[0064] Two fans 13 are started at the same time. After the airflow generated by the fan 13 collides with the wind shield 12, due to the inclination of the top of the wind shield 12, the two airflows are guided upward by the wind shield 12 and merged into one. The upward airflow and the airflow generated by the blowing device 6 undergo convection inside the processing chamber 1. The airflow after convection spreads in all directions and further hits the inner wall of the processing chamber 1 with dust.

[0065] like Figure 9 As shown, in certain embodiments, the dust suppression device 9 includes an atomizing nozzle 901 that extends through the processing chamber 1 and is aligned with the inner wall of the processing chamber 1. When airflow collides within the processing chamber 1, a small amount of dust particles will move upward and adhere to the inner wall of the processing chamber 1. Upon activation of the dust suppression device 9, the atomizing nozzle 901 sprays mist toward the inner wall of the processing chamber 1, forming small droplets that carry the dust particles downward and into the collection assembly 2.

[0066] like Figure 10As shown, in some embodiments, the sliding assembly 5 includes a connecting block 501, which is fixedly connected to the two ends of the outer wall of the processing chamber 1, and a connecting groove 502 is provided on the contact surface of the connecting block 501 and the processing chamber 1, and a through hole is provided at the connection between the processing chamber 1 and the connecting groove 502. The inside of the connecting groove 502 is fixedly connected to an electric guide rail 503, and a connecting rod 1 504 is slidably connected to the electric guide rail 503. One end of the connecting rod 1 504 is slidably connected to the electric guide rail 503, and the other end of the connecting rod 1 504 is fixedly connected to a sealing plate 1 505. A fixing rod 506 is fixedly connected to the two sealing plates 1 505, and both ends of the fixing rod 506 are fixedly connected to the two sealing plates 1 505. A milling cutter 507 is slidably connected to the bottom of the fixed rod 506, and the milling cutter 507 is driven to slide on the fixed rod 506 by starting the fixing rod 506. The milling cutter 507 is used for processing aluminum tubes.

[0067] like Figure 8 As shown, in some embodiments, a spray device 18 is fixed to the side of the windshield 12, and the spray device 18 and the milling cutter 507 are in the same direction relative to the windshield 12. The spray device 18 is used to spray anti-condensation agent. The spray device 18 includes a nozzle 19, and the direction of the nozzle 19 is toward the clamping device 11.

[0068] When the aluminum tube is processed, the spray device 18 sprays the anti-condensation agent on the processed aluminum tube, which effectively prevents condensation from occurring during the operation of the heater.

[0069] like Figure 1 As shown, in some embodiments, a material inlet is opened on the surface of the processing chamber 1, and a sealing door 4 is slidably connected to the material inlet, and the sealing door 4 is used to seal the internal space of the processing chamber 1.

[0070] Embodiment 1: In this embodiment, the grooving of the aluminum tube is realized, and the surface of the aluminum tube is processed by the clamping assembly 11 and the milling cutter 507.

[0071] Specifically, when the device processes the aluminum tube of the skive-tooth type heater, the aluminum tube is fixed on the clamping device 11. At this time, the aluminum tube is directly below the milling cutter 507. The fixing rod 506 is started, and the fixing rod 506 drives the milling cutter 507 to move toward one end of the aluminum tube. When the milling cutter 507 moves to the top of the aluminum tube, the fixing rod 506 is closed, and the milling cutter 507 and the electric guide rail 503 are started. The electric guide rail 503 drives the connecting rod 504, the sealing plate 505 and the fixing rod 506 to move downward, and the fixing rod 506 drives the milling cutter 507 to move downward.

[0072] Assume that the depth of the groove to be cut on the surface of the aluminum tube is a, and the distance from the bottom end of the milling cutter 507 to the surface of the aluminum tube is b. When the distance the milling cutter 507 moves downward is c=a+b, the electric guide rail 503 stops, the fixed rod 506 is started, and the milling cutter 507 moves toward the other end of the aluminum tube on the fixed rod 506. When the milling cutter 507 leaves the aluminum tube from the other end, the milling cutter 507 is closed, and the milling cutter 507 is returned to its original position by starting the electric guide rail 503 and the fixed rod 506. The processing of the aluminum tube is completed and sent to the next process.

[0073] When different shapes and sizes of slots for different aluminum tubes are required, milling cutters 507 of different models and structures can be replaced.

[0074] When processing aluminum tubes, aluminum chips and dust are inevitably generated. By starting one of the blowing devices 6 to blow air into the interior of the processing chamber 1, the direction of the air flow blown out by the blowing device 6 is turned obliquely downward by controlling the direction of the vent of the wind direction control component 105. When the air flow enters the interior of the processing chamber 1, it collides with the inner wall of the processing chamber 1. Since the processing chamber 1 is cylindrical, the air flow inside the processing chamber 1 is spiral downward. The air flow inside the processing chamber 1 drives the dust generated during the processing of the aluminum tube to perform a downward circular motion in the processing chamber 1. Since the dust itself contains mass, centrifugal force is generated when the dust performs a circular motion. Under the action of the centrifugal force, the dust collides with the inner wall of the processing chamber 1. When the dust collides with the inner wall of the processing chamber 1, it slides down.

[0075] When the dust mass is small, the centrifugal force generated is not enough to make the dust itself hit the inner wall of the processing chamber 1. At this time, the dust will hit the blade 102 and slide down on its upper surface. When the dust falls into the collection trough 103, it will be collected. The small dust accumulates inside the collection trough 103 to prevent it from floating again inside the processing chamber 1 during the downward sliding process.

[0076] By starting motor 1 205, the motor 1 main shaft of motor 1 205 drives the bevel gear 204 to rotate, and the bevel gear 204 drives the conical cylinder 202 to rotate through the meshing connection with the conical teeth 203. When the dust in the processing chamber 1 falls to the inner wall of the conical cylinder 202, the rotating dust passing through the conical cylinder 202 is finally gathered inside the spiral groove 206 and forms a dust flow that flows to the inside of the storage chamber 3.

[0077] By starting one of the fans 13, the fan 13 blows the aluminum chips and dust generated when processing the aluminum tube on the clamping device 11 from the support plate 10 to the inner wall of the processing chamber 1. The wind blown by the fan 13 carries the aluminum chips and dust and hits the inner wall of the processing chamber 1 and then rebounds to the surroundings. By controlling the direction of the vent of the wind direction control component 105, the air flow blown out by the blowing device 6 is directed downward, and most of the aluminum chips and dust are blown to the collecting component 2, while a small part of the aluminum chips and dust floats inside the processing chamber 1.

[0078] When processing the dust floating in the processing chamber 1, by turning on the second motor 16, the second motor 16 drives the second connecting rod 15 to rotate, and the second connecting rod 15 drives the sliding rod 14 and the wind shield 12 to rotate. When the wind shield 12 rotates to be in the same straight line with the air outlets of the two fans 13, the second motor 16 stops.

[0079] The two fans 13 are started at the same time. When the airflow generated by the fans 13 collides with the wind shield 12, the two airflows generated by the fans 13 are guided upward by the wind shield 12 and merged into one airflow because the top of the wind shield 12 is inclined and concave inward.

[0080] At the same time, the upward airflow and the downward airflow generated by the blowing device 6 convect inside the processing chamber 1. The convected airflow spreads in all directions and further hits the inner wall of the processing chamber 1 with dust.

[0081] When the airflow inside the processing chamber 1 collides with the inner wall, a small amount of dust will move upward and adhere to the inner wall of the processing chamber 1. By turning on the dust reduction device 9, the atomizing nozzle 901 sprays mist toward the inner wall of the processing chamber 1 and forms small water droplets that slide down into the collecting component 2 with the dust. During the sliding process, the small water droplets further clean the aluminum chips and dust inside the conical cylinder 202, and the collection of aluminum chips and dust is completed.

By starting one of the blowing devices (6), the interior of the processing chamber (1) is blown. By controlling the direction of the vent of the wind direction control member (105), the direction of the airflow blown out by the blowing device (6) is turned obliquely downward. When the airflow enters the interior of the processing chamber (1), it collides with the inner wall of the processing chamber (1). Since the processing chamber (1) is cylindrical, the airflow inside the processing chamber (1) is spiral downward. The airflow inside the processing chamber (1) drives the dust generated during the processing of the aluminum tube to perform a downward circular motion in the processing chamber (1). Since the dust itself has mass, centrifugal force is generated when the dust performs a circular motion. Under the action of the centrifugal force, the dust collides with the inner wall of the processing chamber (1). When the dust collides with the inner wall of the processing chamber (1), it slides downward.

The small dust accumulates inside the collection trough (103) to prevent it from floating again inside the processing chamber (1) during the process of sliding down. By starting the motor 1 (205), the motor 1 main shaft of the motor 1 (205) drives the bevel gear (204) to rotate, and the bevel gear (204) drives the conical cylinder (202) to rotate through meshing connection with the conical teeth (203). When the dust in the processing chamber (1) falls onto the inner wall of the conical cylinder (202), the rotating dust passing through the conical cylinder (202) is finally gathered inside the spiral groove (206) and forms a dust flow toward the inside of the storage chamber (3); By starting one of the fans (13), the fan (13) blows air to blow aluminum chips and dust generated when the aluminum tube is processed on the clamping device (11) from the support plate (10) to the inner wall of the processing chamber (1). The air blown by the fan (13) carries the aluminum chips and dust and hits the inner wall of the processing chamber (1) and then rebounds to all sides. By controlling the direction of the ventilation port of the wind direction control member (105), the air flow blown by the blowing device (6) is directed downward, and most of the aluminum chips and dust are blown to the collecting component (2), while a small part of the aluminum chips and dust floats inside the processing chamber (1).
