Description

Technical Field

[0001] This utility model belongs to the field of hot air blower technology, specifically a stepped heating hot air blower and its processing equipment. Background Technology

[0002] Currently, common stepped heating hot air blowers mainly achieve gradual compression and heating of air by setting multiple baffles in the air duct inside the casing. The core principle is that when air flows through the air duct driven by a fan, the baffles create compression zones of different densities. The airflow generates high temperatures during repeated impacts, ultimately outputting hot air with stepped heating. To achieve this effect, multiple baffles need to be welded to specific locations on the inner wall of the metal casing. The spacing, angle, and fit of the baffles to the inner wall directly affect the heating efficiency and stability of the hot air.

[0003] Traditional processing of this type of hot air blower mainly relies on manual operation: first, lines are drawn on the inner wall of the casing duct to mark the welding points for the baffles; then, workers hold the baffles to fit the marked positions and simultaneously use a welding gun to spot weld them in place. This process has significant drawbacks: 1. Each baffle must be held and welded manually in sequence, making the process cumbersome and inefficient; 2. It is difficult to ensure that the baffles and the inner wall of the casing duct remain in a tight fit during the manual holding process, which can easily lead to welding gaps and affect the welding effect; 3. Each new casing needs to be re-marked, and due to visual errors caused by manual marking and the lack of a unified benchmark, the welding positions of the baffles in the same batch of products are difficult to keep consistent.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, by welding multiple first baffles circumferentially to the inner wall of the curved surface of the annular cavity, and welding a second baffle to the inner wall of the air outlet cavity on the side tangential to the annular cavity, the airflow is guided by multiple baffles to form a spiral compression within the annular cavity, significantly enhancing the airflow impact intensity and residence time. At the same time, by utilizing the circumferential distribution of the first baffles and the flow obstruction effect of the second baffles at the tangential connection, the airflow density is increased in a stepwise manner, greatly improving the heat energy conversion efficiency. In addition, the structural design of welding the baffles directly to the inner wall of the cavity not only reduces the risk of airflow leakage but also strengthens the stability of the baffles against airflow impact, thereby ensuring the long-term heat output efficiency and structural reliability of the hot air blower.

[0018] 2. In this utility model, the inner shell is pressed by a liftable negative pressure shell, and the inner cavity of the negative pressure shell is drawn into a negative pressure state by a negative pressure pipe. With the help of the clamping component, the first baffle and the second baffle to be welded are easily clamped. At the same time, the downward pressing component can always apply a downward force to the clamping component during the welding process, so that the bottom of the first baffle and the second baffle are always in a tight state with the inner lower surface of the inner shell during the welding process. The pressing component can always apply a pushing force to the downward pressing component during the welding process, which, together with the clamping component, makes it easy for one side of the first baffle and the second baffle to always be in a tight state with the side wall of the inner shell during the welding process, ensuring that welding gaps are not easily generated during the welding process, thereby improving the welding effect.

[0019] 3. In this utility model, the sliding cooperation between the guide rail and the welding mechanism facilitates continuous automated welding of the first baffle and the second baffle, significantly improving processing efficiency. Attached Figure Description

Detailed Implementation

[0031] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0032] like Figures 1-2 As shown, this utility model is a stepped heating hot air blower, including an inner shell 100, an impeller assembly 104, and a drive motor 105. The drive motor 105 drives the impeller assembly 104 to rotate. The rotating impeller assembly 104 causes the airflow entering the inner shell 100 to collide and generate hot air. The inner shell 100 includes an annular cavity 101, an air outlet cavity 102, and an air inlet cover 103. The annular cavity 101 and the air outlet cavity 102 are connected. The air inlet cover 103 is connected to the side of the annular cavity 101 away from the drive motor 105. Multiple first baffles 1011 are welded circumferentially to the inner sidewall of the curved surface of the annular cavity 101. A second baffle 1021 is welded to the inner wall of the air outlet cavity 102 on the side tangent to the annular cavity 101.

[0033] It should be noted that during use, the drive motor 105 drives the impeller assembly 104 to rotate at high speed, drawing airflow from the air inlet cover 103 into the annular cavity 101. The airflow is blocked step by step by multiple first baffles 1011 welded circumferentially within the annular cavity 101, forming a spiral compression path, which increases the airflow density in a stepwise manner, greatly improving the counter-current strength and heat energy conversion efficiency. The compressed high-temperature airflow enters the air outlet cavity 102 tangentially, and is further pressurized and guided by the second baffle 1021 welded at the tangential connection, completely eliminating eddy current energy loss and ensuring stable output of high-temperature airflow.

[0034] like Figures 1-2 As shown, the first baffle 1011 and the second baffle 1021 have the same structure. The outer shell 200 that matches the inner shell 100 is sleeved on the outside of the inner shell 100, and a heat insulation layer 201 is filled between the outer shell 200 and the inner shell 100.

[0035] It should be noted that the first baffle 1011 and the second baffle 1021 adopt the same structure, so that the airflow compression characteristics of the annular cavity 101 and the tangential outlet are consistent, which significantly reduces turbulence and improves the uniformity of heat energy conversion. The insulation layer 201 filled between the outer shell 200 and the inner shell 100 effectively blocks the heat loss of hot air. At the same time, the composite structure of the double shell and the insulation layer 201 is conducive to absorbing high-frequency vibration, greatly reducing noise and extending the service life of the equipment.

[0036] like Figures 3-10 As shown, this utility model embodiment provides a processing equipment for a stepped heating hot air blower, used to process the aforementioned stepped heating hot air blower. It includes a processing table 300, a guide rail 301 defining the position of the inner shell 100 mounted on the processing table 300, and a welding mechanism 400 slidably mounted on the guide rail 301. Above the processing table 300 is a negative pressure shell 500 for pressing the inner shell 100 and capable of being raised and lowered. The negative pressure shell 500 is equipped with a first baffle 1011 and a second baffle 1011. 21 Corresponding positioning mechanism; the positioning mechanism includes a clamping member 600, a pressing component 700, a pressing component 800, and a negative pressure pipe 900. The pressing component 700 is movably disposed on the top of the negative pressure housing 500. The end of the pressing component 700 is connected to the clamping member 600 and applies a downward force to the clamping member 600. The housing is connected to the pressing component 700 and the pressing component 800 respectively through the negative pressure pipe 900, and the pressing component is used to apply a pushing force to the pressing component 700.

[0037] It should be noted that during use, the negative pressure housing 500 to be welded is placed on the processing table 300, and the guide rail 301 is used to limit its movement, controlling the negative pressure housing 500 to descend and press against the inner housing 100. The first baffle 1011 and the second baffle 1021 to be welded are respectively inserted into the respective clamping components 600. The negative pressure pump 501 is started to first draw the gas in the clamping components 600 through the negative pressure pipe 900 to achieve negative pressure clamping. Then, the pressing component 700 and the clamping component 80 are extracted. The gas inside the chamber causes the pressing assembly 700 to drive the clamping member 600 to press the first baffle 1011 and the second baffle 1021 vertically downwards. At the same time, the pressing assembly 800 generates a lateral thrust under negative pressure, so that the first baffle 1011 and the second baffle 1021 are always in close contact with the inner wall of the inner shell 100, thereby completely eliminating the assembly gap. The welding mechanism 400 slides along the guide rail 301 to each positioning point, so that the first baffle 1011 and the second baffle 1021 can be welded sequentially.

[0038] like Figures 3-5 As shown, a gantry 302 is installed on the top of the processing table 300. A cylinder 303 is installed on the top of the gantry 302 to drive the negative pressure housing 500 to rise and fall. A negative pressure pump 501 for extracting gas from its internal cavity is installed on the top of the negative pressure housing 500, and an air inlet valve 502 is installed on the top of the negative pressure housing 500.

[0039] It should be noted that the cylinder 303 is used to conveniently control the lifting and lowering of the negative pressure housing 500, and the negative pressure pump 501 is started to conveniently extract the air inside the negative pressure housing 500, so as to facilitate the formation of a negative pressure state in its inner cavity. After welding is completed, the air inlet valve 502 is opened to facilitate the automatic replenishment of external gas into the negative pressure housing 500, thereby conveniently canceling the clamping and positioning effect of the positioning mechanism.

[0040] like Figures 5-6 and Figure 8 As shown, the clamping member 600 includes a U-shaped plate 601, a clamping block 602, a tube body 603, a second piston 604, a first U-shaped rod 605, and an isolation sleeve 606. The U-shaped plate 601 has an internal hollow structure, and its inner cavity is connected to the inverted L-shaped tube 703. The two tube bodies 603 are symmetrically connected on both sides of the U-shaped plate 601. The two clamping blocks 602 are symmetrically distributed on the opposite sides of the U-shaped plate 601. One end of the first U-shaped rod 605 is connected to the clamping block 602, and the other end passes through the isolation sleeve 606 and is connected to the second piston 604. The second piston 604 is slidably disposed with the inner cavity of the tube body 603. The isolation sleeve 606 penetrates the side wall of the U-shaped plate 601 and is embedded in the U-shaped plate 601.

[0041] It should be noted that in this embodiment, the distance between the two clamping plates 602 is matched with the thickness of the first baffle 1011 and the second baffle 1021, so that it is not easy to shake after being inserted between the clamping plates 602, thus achieving a preliminary positioning effect. The gas inside the U-shaped plate 601 is drawn out, and the external air pressure will always apply pressure to the second piston 604 in the direction of approaching the clamping block 602, which drives the first U-shaped rod 605 and the clamping block 602 to conveniently position and clamp the first baffle 1011 and the second baffle 1021. In this embodiment, the isolation sleeve 606 can conveniently ensure the sealing of the inner cavity of the U-shaped plate 601 and facilitate the guidance of the first U-shaped rod 605. It should be noted that before clamping the first baffle 1011 and the second baffle 1021, their bottom ends need to contact the inner lower surface of the inner shell 100.

[0042] like Figures 5-7 As shown, the pressing assembly 700 includes a first cylinder 701, a first piston 702, an inverted L-shaped tube 703, a fixing ring 704, and a spring 705. The top of the negative pressure housing 500 has a T-shaped groove 503 corresponding to the first cylinder 701. A T-shaped slider that slides along the T-shaped groove 503 is installed at the bottom of the first cylinder 701. One end of the inverted L-shaped tube 703 is connected to the clamping member 600, and the other end extends into the first cylinder 701 and is connected to the first piston 702. The first piston 702 is slidably disposed within the inner cavity of the first cylinder 701. The fixing ring 704 is fixedly fitted onto the inverted L-shaped tube 703, and the fixing ring 704 is connected to the top of the first cylinder 701 by the spring 705.

[0043] It should be noted that the spring 705 is used to support the inverted L-shaped tube 703. After the clamping member 600 clamps the first baffle 1011 and the second baffle 1021, the gas inside the first cylinder 701 below the first piston 702 is extracted. The external air pressure will always apply downward pressure to the first piston 702. Since the inverted L-shaped tube 703 is fixedly connected to the clamping member 600, it is convenient for the clamping member 600 to always apply downward pressure to it after clamping the first baffle 1011 and the second baffle 1021, so that the first baffle 1011 and the second baffle 1021 can keep in contact with the inner lower surface of the inner shell 100.

[0044] like Figures 5-7 As shown, the pressing assembly 700 also includes a sleeve 706, a connecting frame 707, and a limiting strip 708. The connecting frame 707 is circumferentially disposed on the top of the first cylinder 701, and the other end of the connecting frame 707 is connected to the sleeve 706. The sleeve 706 is sleeved with the inverted L-shaped tube 703. The limiting strip 708 is disposed on the outer tube wall of the inverted L-shaped tube 703, and the inner tube wall of the sleeve 706 is longitudinally provided with a limiting groove for the limiting strip 708 to pass through.

[0045] It should be noted that the limiting groove on the inner wall of the sleeve 706 can be used to limit the limiting strip 708 on the outer wall of the inverted L-shaped tube 703, thereby facilitating the limitation of the rotational freedom of the inverted L-shaped tube 703.

[0046] like Figures 5-6 and Figure 9 As shown, the clamping assembly 800 includes a second cylinder 801, a third piston 802, a second U-shaped rod 803, and a collar 804. The collar 804 is sleeved on the sleeve 706. One end of the second U-shaped rod 803 is connected to the collar 804, and the other end extends into the second cylinder 801 and is connected to the third piston 802. The third piston 802 is slidably disposed within the inner cavity of the second cylinder 801. The second cylinder 801 is fixedly installed on the top of the negative pressure housing 500, and the length direction of the second cylinder 801 is parallel to the length direction of the T-shaped groove 503.

[0047] It should be noted that after the clamping member 600 clamps the first baffle 1011 and the second baffle 1021, the gas inside the second cylinder 801 is drawn away from the side of the third piston 802 away from the second U-shaped rod 803. The external air pressure will always apply pressure to the third piston 802 in the direction close to the first cylinder 701. In conjunction with the second U-shaped rod 803 and the collar 804, it is convenient to apply a thrust to the sleeve 706. In this embodiment, the inner diameter of the sleeve 706 is equal to the outer diameter of the inverted L-shaped tube 703. The sleeve 706 and the inverted L-shaped tube 703 can slide relative to each other. The sleeve 706 can conveniently transmit the thrust directly to the inverted L-shaped tube 703, so that the clamping member 600 can always apply a thrust to the first baffle 1011 and the second baffle 1021, so that they can always maintain a contact and fit with the inner wall of the inner shell 100.

[0048] like Figures 5-6 As shown, the negative pressure fitting 900 includes a first corrugated pipe 901, an L-shaped suction pipe 902, a second corrugated pipe 903, a third corrugated pipe 904, and a horizontal pipe 906 with a valve 905. The bottom end of the L-shaped suction pipe 902 is connected to the inner cavity of the negative pressure housing 500 through the first corrugated pipe 901, and the top end of the L-shaped suction pipe 902 is connected to the inverted L-shaped pipe 703 through the second corrugated pipe 903. The horizontal pipe 906 and the third corrugated pipe 904 are respectively connected and disposed on the two sides of the first cylinder 701 near the bottom. The other end of the third corrugated pipe 904 is connected to the end of the second cylinder 801, and the other end of the horizontal pipe 906 is connected to the L-shaped suction pipe 902. The valve 905 is installed on the horizontal pipe 906.

[0049] It should be noted that when using the device, valve 905 should be closed first. When extracting gas from the negative pressure housing 500, the first corrugated pipe 901, the L-shaped suction pipe 902, and the second corrugated pipe 903 are used to easily extract gas from the inverted L-shaped pipe 703. The inverted L-shaped pipe 703 is connected to the inner cavity of the U-shaped plate 601, which facilitates the extraction of gas from the inner cavity of the U-shaped plate 601, enabling the clamping component 600 to achieve negative pressure clamping. Subsequently, valve 905 should be opened, and the horizontal pipe 906 and the third corrugated pipe 904 are used to easily extract gas from the first cylinder 701 and the second cylinder 801, which facilitates the downward pressure component 700 and the pressing component 800 to achieve downward pressure and horizontal thrust.

[0050] like Figure 4 and Figure 10 As shown, the welding mechanism 400 includes an electric slider 401, a rotary table 402, an inverted L-shaped column 403, an electric push rod 404, a moving plate 405, an inverted U-shaped part 406, a servo motor 407, a lead screw 408, and a welding torch 409. The electric slider 401 slides along the guide rail 301. The rotary table 402 is mounted on the electric slider 401. The inverted L-shaped column 403 is set on the rotary table 402, and the horizontal part of the inverted L-shaped column 403 is provided with a through groove for the moving plate 405 to slide. The electric push rod 404 is mounted on the side wall of the inverted L-shaped column 403 near the top, and the electric push rod 404 is used to control the sliding of the moving plate 405. The two ends of the inverted U-shaped part 406 slide through the moving plate 405 and are connected to the welding torch 409. The servo motor 407 is mounted on the top of the moving plate 405, and the output end of the servo motor 407 is connected to the lead screw 408. The horizontal part of the inverted U-shaped part 406 is threadedly connected to the lead screw 408.

[0051] It should be noted that the electric slider 401 facilitates position adjustment. When the two welding torches 409 are symmetrically distributed above the second baffle 1021, the electric push rod 404 drives the moving plate 405 to move horizontally, thereby adjusting the position of the two welding torches 409 so that they correspond to the gaps on both sides when the second baffle 1021 and the inner wall of the inner shell 100 are in contact. Then, the servo motor 407 is started to drive the lead screw 408 to rotate, causing the inverted U-shaped part 406 to move the welding torches 409 longitudinally downward along the gaps on both sides, thus completing the welding in both directions. Subsequently, the electric push rod 404 is started to drive the moving plate 405 to move laterally, so that the welding torches 409 perform transverse welding along the gap when the second baffle 1021 is in contact with the lower inner surface of the inner shell 100, thus completing the welding of the second baffle 1021. Similarly, by controlling the electric slider 401 to slide along the guide rail 301, the remaining first baffles 1011 can be welded sequentially.

[0052] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
