[0001] This utility model relates to the field of metal surface treatment technology, specifically a metal surface treatment dryer that facilitates the turning of raw materials. Background Technology

[0002] Drying after metal surface treatment is a key step in ensuring treatment effectiveness and improving product quality. Its function is to remove surface moisture or solvents, promote coating curing, enhance adhesion, and prevent corrosion or oxidation. However, traditional drying equipment is not easy to control the uniform rotation of the workpiece, which leads to uneven heating of the metal surface after drying, resulting in unevenness and affecting the quality of the workpiece.

[0003] To overcome the aforementioned deficiencies, existing technology (Chinese Patent No. CN214600177U, Publication Date: 2021-11-05) provides a metal surface spraying and drying device, including a device shell. Support frames are fixedly installed at the four corners of the bottom outer surface of the device shell, and bases are fixedly installed on the bottom outer surfaces of the support frames. The bottom outer surface area of ​​each base is larger than that of the support frames. A hinge is rotatably installed at the left end of the front outer surface of the device shell, and a door cover is fixedly installed on the right outer surface of the hinge. A handle is fixedly installed at the upper right end of the front outer surface of the door cover. The handle controls the opening and closing of the door cover by rotating the hinge left and right. A heating chamber is fixedly installed at the lower end of the interior of the device shell, and a drying chamber is fixedly installed at the middle horizontally inside the device shell. This device rotates the metal casting while maintaining its fixed position, ensuring uniform heating during the drying process, preventing unevenness on the surface of the dried metal casting, improving drying efficiency, and ensuring drying quality.

[0004] The aforementioned mechanism controls the rotation of the metal casting using a rotating mechanism, thereby achieving uniform heating. However, in actual use, problems arise during surface drying. Utility Model Content

[0005] The purpose of this invention is to provide a metal surface treatment dryer that facilitates the turning of raw materials, thereby solving the problem mentioned in the background art that traditional drying equipment is not easy to control the uniform rotation of the workpiece during use, resulting in uneven heating of the metal surface after drying, which leads to unevenness and affects the quality of the workpiece.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal surface treatment dryer that facilitates raw material turning, comprising a drying chamber, a vent at the top of the drying chamber, a fan rotatably connected to the middle of the top of the drying chamber, and a heating pipe positioned above one end of the drying chamber, the heating pipe being located below the fan; a clamping mechanism for positioning the workpiece is provided at the upper end of the drying chamber, the clamping mechanism including a first drive motor, the first drive motor being located on the side of the front end of the drying chamber, a threaded rod being installed at the output end of the first drive motor, and a movable block being threadedly connected to the outer side of the threaded rod, an adjusting plate being installed on one side between the movable blocks, a second drive motor being provided at the front end of the adjusting plate, a clamping plate being installed at the output end of the second drive motor, and a metal workpiece body being engaged and connected at one end between the clamping plates; and airflow angle adjustment mechanisms for adjusting the airflow direction are provided on both the left and right sides of the upper end of the drying chamber.

[0007] Furthermore, lower positioning blocks are provided at both the front and rear ends of the clamping plate, and positioning holes matching the lower positioning blocks are provided at both the front and rear ends of the left and right sides of the metal workpiece body.

[0008] Furthermore, a guide plate is installed at the bottom of the drying oven, and the guide plate is positioned below the metal workpiece body.

[0009] Furthermore, the cross-section of the guide plate is trapezoidal, and the length of the bottom of the guide plate is equal to the length of the bottom of the drying oven.

[0010] Furthermore, the length of the clamping plate is less than the length of the metal workpiece body, and the clamping plate is symmetrical about the vertical central axis of the metal workpiece body.

[0011] Furthermore, the wind direction angle adjustment mechanism includes a drive gear, which is rotatably connected to the upper front end of the drying chamber. Driven gears mesh on both the left and right sides of the drive gear, and guide plates are rotatably connected to the left and right sides inside the drying chamber.

[0012] Furthermore, the guide plate is connected to the driven gear via a connecting rod, and the guide plate is positioned above the metal workpiece body.

[0013] Furthermore, mounting plates are installed at both the front and rear ends of the drying oven, and bolts are threaded onto the surface of the mounting plates. Threaded grooves matching the bolts are opened on both the left and right sides of the surface of the drying oven.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The metal workpiece body is clamped and fixed by the clamping mechanism. The adjusting plate will push the clamping plate and the lower positioning block to move and make the lower positioning block engage with the positioning hole. After the metal workpiece body is fixed, its angle can be adjusted by the flipping mechanism. The output end of the second drive motor rotates. Since the lower positioning block and the positioning hole are engaged, the second drive motor will drive the metal workpiece body to rotate at a uniform speed. This allows the metal workpiece body to maintain a uniform rotation speed during the drying process, thereby achieving uniform heating and avoiding uneven heating that could lead to unevenness during drying.

[0016] Furthermore, the heating element can heat the air below the fan, and the fan blows air downwards, allowing the surface of the metal workpiece to fully contact the hot air and achieve the drying process.

[0017] Furthermore, the output end of the first drive motor can rotate and drive the threaded rod to rotate. The threaded rod and the movable block are connected by a thread, so that the movable block can be driven by the rotation of the threaded rod to achieve horizontal movement. During the movement of the movable block, the adjusting plate will move synchronously. The adjusting plate clamps and fixes the metal workpiece body in position during the movement, effectively avoiding the instability of clamping the metal workpiece body during the movement.

[0018] 2. The motor drives the drive gear to rotate. Since the drive gear meshes with the two driven gears, the drive gear rotates synchronously when it rotates. The two driven gears rotate in the same direction, which in turn causes the guide plate connected to the driven gears to rotate in the same direction. The angle adjusted by the rotation of the guide plate allows the air blown by the fan to fall evenly on the surface of the metal workpiece and heat it.

[0019] Furthermore, the angle of the fan during air blowing is guided and adjusted to prevent the fan from blowing downwards all the time, which could cause the temperature in the middle of the metal workpiece surface to be too high. By adjusting the angle of the guide plate, the temperature of the metal workpiece surface can be made more uniform. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: As Figures 1-5 The technical solution shown addresses the problem of uneven heating caused by the inconvenience of adjusting the angle of metal castings during drying. This metal surface treatment dryer, which facilitates raw material turning, discloses a turning mechanism, including a drying chamber 1. The top of the drying chamber 1 has a ventilation opening 13. A fan 3 is rotatably connected to the middle of the top of the drying chamber 1. A heating pipe 4 is located above one end of the drying chamber 1, below the fan 3. A clamping mechanism for positioning the workpiece is located at the upper end of the drying chamber 1. The clamping mechanism includes a first drive motor 8, which is located on the side of the front end of the drying chamber 1. A second drive motor 12... A clamping plate 14 is installed at the output end, and a metal workpiece body 17 is engaged with one end of the clamping plate 14. Lower positioning blocks 15 are provided at both the front and rear ends of the sides of the clamping plate 14, and positioning holes 16 matching the lower positioning blocks 15 are provided at both the front and rear ends of the left and right sides of the metal workpiece body 17. A guide plate 2 is installed at the bottom of the drying oven 1, and the guide plate 2 is located below the metal workpiece body 17. The cross-section of the guide plate 2 is trapezoidal, and the length of the bottom of the guide plate 2 is equal to the length of the bottom of the drying oven 1. The length of the clamping plate 14 is less than the length of the metal workpiece body 17, and the clamping plate 14 is symmetrical about the vertical central axis of the metal workpiece body 17.

[0029] In this example, the workpiece to be dried is placed inside the drying chamber 1, clamped and fixed by a clamping mechanism, and then the metal workpiece body 17 is rotated by a flipping mechanism to adjust its angle, thereby ensuring more uniform heating of the metal workpiece body 17 during drying; Figure 2 and Figure 5 As shown, the metal workpiece body 17 is clamped and fixed by the clamping mechanism. The adjusting plate 11 pushes the clamping plate 14 and the lower positioning block 15 to move, causing the lower positioning block 15 to engage with the positioning hole 16. This allows the metal workpiece body 17 to be fixed and its angle to be adjusted by the flipping mechanism. The output of the second drive motor 12 rotates. Because the lower positioning block 15 and the positioning hole 16 remain engaged, the second drive motor 12 rotates the metal workpiece body 17 at a uniform speed. This ensures that the metal workpiece body 17 maintains a uniform rotation speed during drying, achieving uniform heating and preventing uneven heating that could lead to unevenness during drying, thus increasing overall stability during use. Figure 2 As shown, the heating tube 4 can heat the air below the fan 3, and the fan 3 blows air downwards, so that the surface of the metal workpiece body 17 can fully contact the hot air to achieve the drying process.

[0030] Example 2: Figures 1-3 The technical solution shown addresses the problem of inconvenient airflow angle adjustment during surface drying, which can lead to localized high temperatures in metal castings during drying and blowing processes. This metal surface treatment dryer, designed for easy material turning, discloses an airflow angle adjustment mechanism. Airflow angle adjustment mechanisms are installed on both the left and right sides of the upper part of the drying chamber 1. Each airflow angle adjustment mechanism includes a drive gear 5, which is rotatably connected to the upper front end of the drying chamber 1. Driven gears 6 mesh on both sides of the drive gear 5, and guide plates 7 are rotatably connected to the left and right sides of the drying chamber 1. The guide plates 7 are connected to the driven gears 6 via connecting rods and are positioned above the metal workpiece body 17.

[0031] In this example, such as Figure 1 and Figure 3As shown, the motor drives the drive gear 5 to rotate. Since the drive gear 5 meshes with the two driven gears 6, the drive gear 5 rotates synchronously with the driven gears 6. The two driven gears 6 rotate in the same direction, which in turn causes the guide plate 7 connected to the driven gears 6 to rotate in the same direction. The angle adjusted by the rotation of the guide plate 7 guides and adjusts the angle of the fan 3 when blowing air, preventing the fan 3 from blowing air downwards all the time, which would cause the temperature in the middle of the surface of the metal workpiece body 17 to be too high. The angle adjustment of the guide plate 7 makes the temperature of the surface of the metal workpiece body 17 more uniform.

[0032] Example 3: Figure 1 , Figure 2 , Figure 4 and Figure 6 The technical solution shown addresses the problem of difficulty in adapting to different metal casting sizes during drying: This metal surface treatment dryer, which facilitates raw material flipping, discloses a clamping mechanism. A threaded rod 9 is installed at the output end of the first drive motor 8, and a movable block 10 is threadedly connected to the outer side of the threaded rod 9. An adjusting plate 11 is installed on one side between the movable blocks 10, and a second drive motor 12 is provided at the front end of the adjusting plate 11. Mounting plates 18 are installed at both the front and rear ends of the drying chamber 1, and bolts 19 are threadedly connected to the surface of the mounting plates 18. Threaded grooves 20 matching the bolts 19 are opened on both the left and right sides of the surface of the drying chamber 1.

[0033] In this example, the output of the first drive motor 8 can rotate and drive the threaded rod 9 to rotate. The threaded rod 9 is threadedly connected to the movable block 10, allowing the movable block 10 to move horizontally driven by the rotation of the threaded rod 9. During the movement, the movable block 10 synchronously drives the adjusting plate 11 to move, and the adjusting plate 11 clamps and fixes the metal workpiece body 17 in position during the movement, effectively preventing the metal workpiece body 17 from being unstable during the movement. Due to the advancement of the adjusting plate 11, the lower positioning block 15 and the positioning hole 16 can be more tightly connected, thereby achieving stable clamping of the metal workpiece body 17. The two threaded rods 9 are connected by a sprocket transmission mechanism, so the two threaded rods 9 rotate at the same speed. At the same time, a tensioner can be set on the sprocket transmission mechanism to ensure the belt wrap angle and avoid the belt wrap angle being too small. Figure 6 As shown, the height of the mounting plate 18 can be adjusted as needed through the threaded connection between the bolt 19 and the threaded groove 20, thereby allowing the metal workpiece body 17 to adjust its contact position with the fan 3 as needed during the drying process.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
