Description

Technical Field

[0001] This utility model belongs to the field of household ceramics production technology, and in particular relates to a pot spraying fixture. Background Technology

[0002] Often, the inner bottom surface of cookware requires spray coating. This coating typically serves two purposes: visual and functional. Due to various concerns, the visual aspect is relatively less frequently used on the inner bottom of cookware. Functional coatings, however, are more common, with different layers applied depending on the specific function. For example, one application that has shown promising results and is gradually being marketed involves spraying a magnetic material onto the inner bottom of ceramic cookware, then covering it with a layer of ceramic material. This creates a built-in magnetic layer on the bottom of the ceramic cookware, allowing it to be used on induction cooktops. Regardless of the specific function, during the actual application, the cookware needs to be masked according to the designated spraying area to ensure accurate application of the coating. This usually requires the use of appropriate clamps, which hold the cookware on the conveyor belt of the spraying line and also hold the masking components to the cookware. On the production site, the fixtures used in actual applications are usually required to have the aforementioned functions, and to allow for quick and easy assembly and disassembly of cookware and lids. Summary of the Invention

[0003] This invention provides a cookware spraying fixture to solve the problems mentioned in the background art.

[0004] The technical problem solved by this utility model is achieved by the following technical solution:

[0005] A cookware spraying fixture includes a bracket, a positioning component, a clamping component, a cookware, and a cover plate. The bracket is installed on the conveyor belt of the spraying equipment. The positioning component is installed on the bracket to center the cookware. The clamping component is installed on the bracket and magnetically connected to the cover plate to press the cookware tightly. The cover plate covers the cookware and provides a covering function.

[0006] The support frame has a cross-shaped structure with four arms, each with a through-groove running vertically through the center. Four positioning components are included: a positioning rod, a positioning head, and a positioning nut. The positioning rod passes through the groove, with a positioning head at its top. A positioning nut is installed on each of the upper and lower arms of the positioning rod. These four positioning components clamp the cookware in place at the center of the support frame. A pair of clamping components are also included, mounted on opposite arms of the support frame. Each clamping component consists of a round rod, a clamping nut, a spring, a plate, and a magnet. The round rod passes through the groove, with a clamping nut installed on each of the upper and lower arms of the round rod. These two clamping nuts allow adjustment of the round rod's height and distance from the support frame's center, accommodating different cookware heights and diameters. A spring connects to the top of the round rod, a plate connects to the top of the spring, and a magnet connects to the top of the plate. The cookware is placed on the support frame and centered by the positioning components. The rim of the cookware forms the contact surface with the lid, and the clamping components are located on the outer side of the rim. The lid consists of a round lid and a curved edge. The round lid is placed on the rim of the pot, and the outer edge of the round lid is attracted to the magnet that is lifted upwards.

[0007] Furthermore, the support has a base cylinder at its center, which connects the entire fixture to the spraying equipment's production line. Of course, the specific connection method between the support and the production line should match the specific structural form of the spraying equipment's production line; it can be designed as needed.

[0008] Furthermore, the spring is connected to the round rod and the flat plate by welding. This connection method allows the spring to maintain a neutral position. When the spring is stretched, the magnet attracts the cover plate, pulls the cover plate downwards and presses the cookware.

[0009] Furthermore, the magnet is connected to the plate by adhesive bonding, which ensures a firm connection without affecting the magnet's function.

[0010] Furthermore, the inner side of the round lid has a curved edge that extends downwards from the inside of the cookware, providing better coverage of the interior and preventing the coating from hitting the side walls of the cookware during the spraying process. In addition, the specific shape of the hollowed-out part in the center of the lid can be configured according to the shape required for spraying.

[0011] The beneficial effects of this utility model are:

[0012] This invention relates to a clamping operation in the spraying process of cookware, particularly suitable for clamping operations when spraying a magnetic coating onto the inner bottom of ceramic cookware. It features four flexibly adjustable positioning components, allowing for easy centering of cookware of different diameters. It also includes a pair of clamping components that work with a magnetically attached lid to firmly hold the cookware in place. The entire production line operation requires only a small number of operators. Attached Figure Description

[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0018] See Figures 1-3 The cookware spraying fixture shown includes a bracket 10, a positioning element 20, a clamping element 30, a cookware 40, and a cover plate 50. The bracket 10 is installed on the conveyor belt of the spraying equipment. The positioning element 20 is installed on the bracket 10 to center the cookware 40. The clamping element 30 is installed on the bracket 10 and magnetically connected to the cover plate 50 to press the cookware 40 tightly. The cover plate 50 covers the cookware 40, covering the area to be sprayed and exposing the area to be sprayed while covering the area not to be sprayed.

[0019] The bracket 10 has a cross-shaped structure with four support arms 11. Each support arm 11 has a vertically extending groove 12 in the center. The bottom of the bracket 10 has a base cylinder 13 in the center, which connects the entire fixture to the production line of the spraying equipment. Of course, the specific docking method between the bracket 10 and the production line should match the specific structural form of the spraying equipment production line, and can be designed as needed.

[0020] There are four positioning components 20, each including a positioning rod 21, a positioning head 22, and a positioning nut 23. The positioning rod 21 passes through the slide groove 12, and the top of the positioning rod 21 has a positioning head 22. The positioning head 22 is made of rubber material, which can effectively clamp the cookware 40 while avoiding damage to the side wall of the cookware 40. A positioning nut 23 is installed on the upper and lower parts of the support arm 11 on the positioning rod 22. The two positioning nuts 23 can adjust the height of the positioning head 22 to adapt to the height of the side wall of the cookware 40, and can also clamp the positioning rod 21 in a suitable position on the slide groove 12 to adapt to the diameter of the cookware 40. The four positioning components 20 position and clamp the cookware 40 in the center of the bracket 10. In many cases, the cookware 40 needs to be rotated by the bracket 10 during the spraying process; therefore, it is important to accurately center and clamp the cookware 40 on the bracket 10. Since cookware of the same type 40 only requires adjusting the position of the positioning element 20 once, and considering the centering function, four positioning elements 20 are needed. For each type of cookware, after adjusting the positions of the four positioning elements 20, the cookware only needs to be placed on the support 10 from top to bottom and confined within the four positioning elements 20 to complete the centering placement.

[0021] The clamping member 30 is a pair, which are respectively installed on two opposite support arms 11 of the bracket 10. According to the function and structural relationship, the clamping member 30 is installed outside the positioning member 20. The clamping member 30 includes a round rod 31, a clamping nut 32, a spring 33, a plate 34, and a magnet 35. The round rod 31 passes through the slide groove 12. A clamping nut 32 is installed on the upper and lower support arms 11 of the round rod 31. The two clamping nuts 32 can adjust the height of the round rod 31 and its distance from the center of the bracket 10 to adapt to different heights and diameters of the cookware 40. The top of the round rod 31 is connected to the spring 33, the top of the spring 33 is connected to the plate 34, and the top of the plate 34 is connected to the magnet 35. The spring 33 is connected to the round rod 31 and the plate 34 by welding. This connection method allows the spring 33 to maintain a neutral position. When the spring 33 is stretched, the magnet attracts the cover plate 50, pulls the cover plate 50 downward and presses the cookware 40. The magnet 35 is connected to the plate 34 by adhesive bonding, which ensures a firm connection and does not affect the function of the magnet.

[0022] The cookware 40 is placed on the support 10 and centered by the positioning member 20. The rim 41 of the cookware 40 is the contact surface of the lid 50, and the clamping member 30 is located on the outside of the rim 41.

[0023] The cover plate 50 includes a round cover 51 and a curved edge 52. The round cover 51 is placed on the rim 41 of the cookware 40. The outer edge of the round cover 51 is attracted to the upward-lifting magnet 35. After the magnet 35 is attracted to the round cover 51, under the action of the spring 33, the magnet 35 pulls the round cover 51 downward and presses the cookware 40 onto the support 10. The round cover 51, on the one hand, works with the clamping member 30 to press the cookware 40, and on the other hand, it covers the cookware 40 during the spraying process, accurately defining the spraying area. In this embodiment, a layer of magnetic conductive material coating of a certain thickness needs to be sprayed on the bottom surface of the ceramic cookware so that the ceramic cookware can be used with an induction cooker. The round cover 51 has a curved edge 52 on its inner side, which extends downward inside the cookware 40, providing better coverage of the inside of the cookware 40 and preventing the spray from hitting the side wall of the cookware 40 during the spraying process. Furthermore, the specific shape of the hollowed-out portion in the center of the cover plate 50 can be configured according to the shape required for spraying. Additionally, the outer diameter of the cover plate 50 needs to be specifically designed according to the diameter of the cookware.

[0024] The working principle of this invention is as follows: First, adjust the positions of the four positioning members 20 according to the shape and size of the cookware 40, so that the four positioning members 20 accurately position the center of gravity of the cookware 40 at the center of the support 10. Then, simply place the cookware 40 inside the four positioning members 20. Next, adjust the position of the clamping member 30 according to the height and diameter of the cookware 40, place the cover plate 50 on the cookware 40, and pull up the flat plate 34 so that the magnet and the cover plate 50 attract each other. This completes the placement of one cookware 40 on the clamp. When changing the cookware, simply reverse the above steps. It is very convenient and quick, requiring only a few personnel on the production site.

[0025] The above embodiments mainly illustrate the cookware spraying fixture of this utility model. Although only a limited number of embodiments and technical features have been described, those skilled in the art should understand that this utility model can be implemented in many other forms without departing from its spirit and scope. Therefore, the illustrated embodiments are considered illustrative and not limiting, and this utility model may cover various modifications and substitutions without departing from the spirit and scope of this utility model as defined by the appended claims.
