[0002] Air fryers have seen rapid growth in the Chinese market in recent years, with demand increasing year by year. Currently, most air fryers on the market have an inner pot inside the pot. To improve its durability, protection, and non-stick properties, the inner pot needs to be coated during manufacturing.

[0003] In the existing technology, the product to be sprayed is placed on a cross-shaped tooling, which is clamped onto the four side walls of the product and supports the bottom of the product. The product is then rotated for spraying. The front and back sides of the product need to be sprayed and cured twice. The bonding force at the junction of the front and back spraying is not good, which poses a risk of paint peeling and affects the overall spraying quality of the product, resulting in a high scrap rate. Utility Model Content

[0004] This utility model addresses the existing technical problems by providing a support fixture for spraying metal containers.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A support fixture for spraying metal containers includes a support base, an adjusting plate, a support sleeve assembly, and a positioning frame. The positioning frame is installed on the support sleeve assembly, the support sleeve assembly is installed on the adjusting plate, and the adjusting plate is installed on the support base. The positioning frame is provided with two positioning plugs, which are used to correspond to the through holes on the side wall of the metal container. The two positioning plugs are arranged in parallel, and the positioning frame extends upward relative to the support sleeve assembly and has an angle α with the support sleeve assembly, wherein 90°≤α≤150°, so that the positioning plugs are inserted into the through holes.

[0006] Based on the above technical solution, the present invention can be further improved as follows:

[0007] Preferably, the positioning frame includes a bent section, the bend of which is fixed to the upper end of the support sleeve assembly. The bent section is inclined upward relative to the support sleeve assembly, and the included angle between the positioning plug and the support sleeve assembly is β, wherein 120°≤β≤150°.

[0008] Preferably, the two positioning plugs are respectively disposed at both ends of the bent section.

[0009] Preferably, the positioning frame further includes two parallel sections disposed at both ends of the bent section, each of the two parallel sections having a suspended end, and two positioning plugs disposed at the ends of the two suspended ends.

[0010] Preferably, the bent section is frame-shaped, V-shaped, or U-shaped.

[0011] Preferably, the central axis of the positioning plug and the central axis of the parallel segment are on the same straight line.

[0012] Preferably, the positioning plug is fixedly connected to or detachably connected to the positioning frame.

[0013] Preferably, the positioning plug includes a connecting part and a positioning part. The positioning plug is connected to the positioning frame through the connecting part. The connecting part and the positioning part have a smooth transition. The positioning part is conical. Alternatively, a transition part is provided between the connecting part and the positioning part. The positioning part is cylindrical or conical.

[0014] Preferably, the support sleeve assembly includes a support sleeve and an adjusting rod. The adjusting rod has a polygonal cross-section.

[0020] 4. Depending on the volume or shape of the metal container to be coated, the bending section can be set to different shapes to meet the needs of different occasions and improve the flexibility and convenience of use.

[0021] 5. Select a positioning plug with an appropriate structure according to the shape of the through hole on the metal container to be sprayed and the weight of the metal container to meet the support requirements of different metal containers. The structure is simple and the operation is convenient.

[0022] 6. By adjusting the rod in conjunction with the support sleeve, the height of the positioning plug can be adjusted, thereby adjusting the height of the metal container to meet the support requirements of metal containers of different heights, improving the applicability and reducing the cost of use.

[0023] 7. The position of the metal container can be adjusted by the adjustment groove on the adjustment plate, and the distance between the metal container and the spraying equipment can be adjusted to improve the spraying quality and increase the flexibility and convenience of use.

[0035] Example 1

[0036] Reference Figures 1 to 4 As shown, this utility model discloses a support fixture for spraying metal containers, including a support base 1, an adjusting plate 4, a support sleeve assembly, and a positioning frame 10. The positioning frame 10 is mounted on the support sleeve assembly, the support sleeve assembly is mounted on the adjusting plate 4, and the adjusting plate 4 is mounted on the support base 1. The positioning frame 10 is provided with two positioning plugs 11, which are used to correspond to through holes in the side wall of a metal container 12. The metal container 12 is a pot to be sprayed. The two positioning plugs 11 are arranged in parallel, and the positioning frame 10 extends upward relative to the support sleeve assembly and forms an angle α with the support sleeve assembly, where 90°≤α≤150°, so that the positioning plugs 11 can be inserted into the through holes of the metal container 12. During spraying, the opening of the metal container 12 faces upward. Furthermore, the opening of the metal container 12 is parallel to the horizontal plane. The opening of the metal container 12 can float within a range of ±10° to the horizontal plane to avoid excessive tilting and the occurrence of spraying blind spots, thus ensuring the spraying quality of the metal container 12. In this embodiment, the included angle α is 120°, which can ensure both stable support for the metal container 12 and overall stability.

[0037] Furthermore, the positioning frame 10 includes a bent section, the bend of which is fixed to the upper end of the support sleeve assembly. The bent section is inclined upward relative to the support sleeve assembly and is fixed to the support sleeve assembly through the bend, thereby increasing the stability and overall structural strength of the positioning frame 10 and ensuring stable support of the metal container 12.

[0038] The included angle between the positioning plug 11 and the support sleeve assembly is β, where 120°≤β≤150°, ensuring stable support for the metal container 12 and preventing the metal container 12 from detaching from the positioning plug 11. In this embodiment, the bent section of the positioning frame 10 is V-shaped. The positioning frame 10 also includes two parallel sections located at both ends of the bent section. Each of the two parallel sections has a suspended end, and two positioning plugs 11 are located at the ends of the two suspended ends. The parallel sections and the bent section have the same inclination angle, and the central axis of the positioning plug 11 and the central axis of the parallel section are on the same straight line. That is, the included angle between the positioning plug 11 and the support sleeve assembly is also β, which is 120°. This ensures stable support for the metal container 12 and reduces the difficulty of fitting the positioning plug 11 and the positioning frame 10, thereby reducing processing costs.

[0039] Furthermore, the bending section and parallel section of the positioning frame 10 are integrated into one piece, which increases the structural strength of the positioning frame 10, reduces the number of parts, and lowers the processing cost.

[0040] In this embodiment, the positioning plug 11 includes a connecting portion 11.1 and a positioning portion 11.2. The positioning plug 11 is connected to the positioning frame 10 through the connecting portion 11.1. A transition portion is provided between the connecting portion 11.1 and the positioning portion 11.2, with the transition portion having the smallest diameter. The positioning portion 11.2 is cylindrical. The transition portion forms a buffer area, which can effectively reduce the stress concentration between the connecting portion 11.1 and the positioning portion 11.2, and improve the fatigue resistance of the overall structure. The end of the positioning portion 11.2 is provided with rounded corners, which facilitates insertion into the through hole of the metal container 12. The cylindrical positioning portion 11.2 can meet the positioning requirements of fixing the inner hole diameter, ensuring that the metal container 12 can be sprayed normally.

[0041] In this embodiment, the positioning plug 11 is welded and fixedly connected to the positioning frame 10, which increases the overall structural strength and reduces the shaking of the metal container 12.

[0042] In other alternative embodiments, the positioning plug 11 is detachably mounted on the positioning frame 10. By replacing the positioning plug 11 with different sizes according to the size of the through hole on the metal container 12, the ease of use is improved and the cost of use is reduced.

[0043] The support sleeve assembly includes a support sleeve 7 and an adjusting rod 9. The adjusting rod 9 has a polygonal cross-section. The support sleeve 7 has a polygonal positioning hole that extends along the height direction of the support sleeve 7. The upper end of the adjusting rod 9 is connected to the positioning frame 10 by welding, and the lower end of the adjusting rod 9 is inserted into the positioning hole. A locking screw 8 is installed on the side wall of the positioning hole, and the end of the locking screw 8 abuts against the side wall of the adjusting rod 9. The height of the positioning plug 11 is adjusted by the adjusting rod 9 to meet the spraying requirements of metal containers 12 of different heights, thereby improving the flexibility of use. By setting the adjusting rod 9 as a polygonal structure, it is easy for the locking screw 8 to lock the adjusting rod 9, increasing the firmness of the installation of the adjusting rod 9, preventing the metal container 12 from shaking, and improving the spraying quality.

[0044] A support plate 2 is mounted on the support base 1. An adjustment groove 5 is provided on the adjustment plate 4. The adjustment groove 5 is elongated. The support plate 2 has multiple mounting holes circumferentially. An adjustment screw 6 passes through the adjustment groove 5 and connects to the mounting holes. Moving the adjustment plate 4 along the direction of the adjustment groove 5 can adjust the distance between the metal container 12 to be sprayed and the spraying equipment, ensuring the spraying effect and improving the convenience of use.

[0045] Furthermore, the support area of ​​the support plate 2 is greater than that of the support base 1. By increasing the support area of ​​the adjustment plate 4 through the support plate 2, the overall stability is further improved.

[0046] Example 2

[0047] Reference Figures 5 to 6 As shown, the difference from Embodiment 1 is the structure of the positioning frame 10 and the positioning plug 11; the rest are the same as in Embodiment 1.

[0048] In this embodiment, the bent section of the positioning frame 10 is a frame with an opening on one side. The included angle α between the positioning frame 10 and the support assembly is 90°. Two positioning plugs 11 are respectively disposed at both ends of the bent section. The included angle β between the positioning plugs 11 and the support sleeve assembly is 135°, ensuring stable support for the metal container 12 and preventing the metal container 12 from detaching from the positioning plugs 11. The positioning part 11.2 of the positioning plug 11 is conical. The conical positioning part 11.2 is easier to insert into the through hole of the metal container 12, improving the convenience of positioning the metal container 12 and achieving stable support for the metal container 12.

[0049] Furthermore, the positioning plug 11 is tilted upwards to facilitate its insertion into the through hole of the metal container 12. The end of the positioning frame 10 is provided with a downward-sloping cut, and the bottom of the cut abuts against the outer wall of the metal container 12 to form a contact point. The contact point and the positioning plug 11 cooperate to further improve the stability of the metal container 12 when it is supported. The cut structure can reduce the contact area between the positioning frame 10 and the metal container 12, ensuring the overall coating quality of the metal container 12.

[0050] Example 3

[0051] Reference Figures 7 to 8 As shown, the difference from Embodiment 1 is the structure of the positioning frame 10 and the positioning plug 11; the rest are the same as in Embodiment 1.

[0052] In this embodiment, the bent section of the positioning frame 10 is U-shaped, with two parallel sections at both ends. These two parallel sections are horizontally positioned and each has a suspended end. Two positioning plugs 11 are respectively located at the ends of these suspended ends. The angle between the positioning plug 11 and the support sleeve assembly is β, where β is 150°, ensuring the metal container 12 opens upwards and allowing for complete coating of the metal container 12, guaranteeing the overall coating quality. The connecting portion 11.1 and the positioning portion 11.2 of the positioning plug 11 transition smoothly. The positioning portion 11.2 is conical in shape. During insertion, the conical structure gradually tightens, inserting the positioning plug into the through-hole of the metal container 12, meeting the positioning requirements of different through-holes and improving convenience and versatility during use.

[0053] In use, the positioning plug 11 is inserted into the through hole of the metal container 12. The positioning plug 11 is tilted, so that the opening of the metal container 12 can be kept in a basically horizontal state. The support base 1 is rotatably mounted on the support column through the bearing 3. Multiple support columns are circumferentially mounted on the turntable. When the turntable is active, it drives the support fixture and the metal container 12 to rotate, so that different metal containers 12 are rotated to the spraying station, improving the spraying efficiency. Since the metal container 12 is in a suspended state during spraying, the inside and outside of the metal container 12 can be sprayed at the same time without flipping, which simplifies the spraying process and improves the spraying efficiency and spraying quality.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
