Description

Technical Field

[0001] The present application relates to the technical field of cookware manufacturing, and in particular to a protective tooling and sandblasting device for cookware. Background Art

[0002] During the manufacturing process of cookware, the inner surface of the cookware is usually sandblasted. Figure 1 As shown, sandblasting typically involves using a suction cup 300 to hold the bottom of a pot 302, suspending the pot 302 upside down on the equipment. A spray gun 303 of the sandblasting equipment then swings below the pot 302 to sandblast the inner surface of the pot 302. During the sandblasting process, the spray gun 303, located below the pot, swings beyond the coverage area of ​​the pot 302. Sand particles bounce off the protective ring 301 and onto the outer surface of the pot 302, resulting in poor surface quality during the manufacturing process. This requires additional post-processing to ensure the surface quality of the final pot. Utility Model Content

[0003] The present application aims to at least solve the technical problem in the above-mentioned prior art or related art that the outer surface quality of the cookware during the manufacturing process is poor and requires additional post-processing.

[0004] To achieve the above-mentioned objectives, the first aspect embodiment of the present application provides a protective tool for protecting cookware, wherein the protective tool includes a cover body having a cover cavity, the cover body is used to cover the outer periphery of the cookware so that the cookware is set in the cover cavity, and a sealed cavity is formed between the cover body and the cookware, and a vent hole is opened on the cover body so that the sealed cavity is connected to the outside.

[0005] According to the protective tooling provided by the embodiment of the present application, when in use, the cookware can be inverted and the cover body can be placed on the outside of the cookware. In this case, the cookware is placed in the cover cavity of the cover body, and the cover body is provided with a vent hole, which can connect the sealed cavity with the outside. In this way, during the manufacturing process of the cookware, the vacuum suction cup of the vacuum equipment can dock with the vent hole and evacuate the sealed cavity. When the evacuation reaches a certain level, the cookware can be adsorbed in the cover cavity and suspended to facilitate sandblasting of the inner surface of the cookware. In this way, the cover body can be placed around the outer periphery of the cookware to protect the outer surface of the cookware, thereby ensuring the quality of the outer surface of the cookware without affecting the sandblasting operation of the inner surface, avoiding the trouble of subsequent processing.

[0006] In some embodiments, the cover body includes a cover bottom wall and a ring-shaped cover side wall connected to the cover bottom wall, and the cover bottom wall and the cover side wall enclose each other to form the cover cavity.

[0007] In these embodiments, the cover includes a bottom wall and an annular sidewall connected to the bottom wall. The bottom wall and the sidewall together enclose a cover body with a cover cavity. The cover body of the protective tooling has a substantially similar shape to the cookware. During use, the cookware can be placed within the cover cavity, with the cover body completely covering the outer periphery of the cookware, thereby protecting the outer surface of the cookware and reducing the impact of subsequent sandblasting on the outer surface of the cookware. In addition, the substantially similar shape of the cover body of the protective tooling and the cookware facilitates the sealing of the gap between the two.

[0008] In some embodiments, the protective tooling further comprises a sealing strip, which is provided on the side wall of the cover and is used for sealing contact with the outer surface of the side wall of the pot.

[0009] In these embodiments, a sealing strip can be provided on the sidewall of the cover body, configured to seal against the outer surface of the pot sidewall of the cookware. When the cover body of the protective tooling and the cookware are assembled, the sealing strip tightly adheres to the outer surface of the pot sidewall of the cookware, effectively closing the gap between the cover sidewall and the pot sidewall, thereby ensuring a tight connection between the cover body and the cookware. In this case, on the one hand, sand or other impurities can be prevented from entering the interior space of the protective tooling, thereby avoiding affecting the quality of the outer surface of the cookware. On the other hand, when air is drawn through the vent hole, a vacuum is formed between the cover body and the cookware, ensuring a reliable connection between the two.

[0010] In some embodiments, an annular embedding groove is provided on the side wall of the cover, and the sealing strip is embedded in the embedding groove.

[0011] In these embodiments, the sealing strip is embedded in an annular groove, which provides a fixed installation position for the sealing strip, ensuring that the sealing strip is not easily dislodged during use. In addition, the sealing strip is detachably fixed to the side wall of the cover, allowing for easy replacement and ensuring a good sealing effect during long-term use.

[0012] In some embodiments, the embedding groove is provided on the end surface of the cover side wall, and the pot side wall has an outer flange at the pot opening, so that the installation position of the sealing strip corresponds to the outer flange.

[0013] In these embodiments, an embedding groove is opened on the end face of the side wall of the cover of the protective tooling, and a sealing strip is set in the embedding groove. When in use, the cookware can be turned upside down and the cover body can be turned upside down on the cookware. At this time, the sealing strip and the outer flange of the cookware can abut against each other and can be initially combined under the pressure of external force. After reaching the vacuum equipment, the air in the sealed cavity is extracted through the vent. During the vacuuming process, vacuum adsorption is formed between the cover body and the cookware, so that the cookware can be adsorbed in the cover cavity to be suspended. In this way, the cover body can cover the entire periphery of the cookware to fully protect the outer surface of the cookware (to avoid sandblasting or scratches), thereby ensuring the quality of the outer surface of the cookware without affecting the sandblasting operation of the inner surface.

[0014] In some embodiments, the cover body is made of nylon material, and the sealing strip is a silicone foam sealing strip.

[0015] In these embodiments, by properly selecting the manufacturing material of the cover and using a silicone foam sealing strip, better sealing performance and adaptability can be provided, thereby ensuring the effective operation of the protective tooling and guaranteeing the quality of the outer surface of the cookware.

[0016] In some embodiments, the sealing strip is 1 mm to 1.5 mm higher than the embedding groove.

[0017] In these embodiments, by arranging the sealing strip to be higher than a certain height in the embedded groove, the raised portion can provide additional deformation space. In this way, when the protective tooling and the cookware are assembled together, the sealing strip is easy to deform and better adapt to the shape of the side wall of the cookware and / or the surface unevenness, thereby achieving a tight fit and ensuring the sealing performance of the connection. On the one hand, it helps to prevent sand, gas or other impurities from entering the internal space of the protective tooling, thereby ensuring the quality of the outer surface of the cookware. On the other hand, when air is inhaled through the vent hole, it is conducive to forming a vacuum adsorption between the cover and the cookware, thereby ensuring the reliability of the connection between the two.

[0018] In some embodiments, a welding piece for connecting a pot handle is provided on the outer surface of the pot side wall of the pot. When the pot is arranged in the cover cavity, the cover body can be arranged to cover the outer side of the welding piece.

[0019] In these embodiments, when the cookware is arranged in the cover cavity, the cover side wall is arranged on the periphery of the cookware and covers the outside of the welding piece, which not only ensures the surface quality of the cookware, but also provides local protection for the welding piece, thereby greatly reducing costs and improving production efficiency.

[0020] According to the second aspect of the present application, a sandblasting device is provided, wherein the sandblasting device includes a vacuum device and the protective tooling provided in the above-mentioned embodiments, the vacuum device includes a vacuum suction cup, and the vacuum suction cup can be docked with the vent hole to evacuate the sealed cavity, thereby adsorbing the pot in the cover cavity.

[0021] According to the protective tooling provided in the embodiment of the present application, when in use, the cookware can be inverted and the cover body can be set on the outside of the cookware. In this case, the cookware is placed in the cover cavity of the cover body, and a vent is provided on the cover body, which can connect the sealed cavity with the outside. In this way, when the cookware passes through the vacuum suction cup of the vacuum equipment during the manufacturing process, the vacuum suction cup can dock with the vent and vacuum the sealed cavity. When the vacuum is evacuated to a certain extent, the cookware can be adsorbed in the cover cavity and suspended. In this way, the cover body can be set on the outer periphery of the cookware to protect the outer surface of the cookware, thereby ensuring the quality of the outer surface of the cookware without affecting the sandblasting operation of the inner surface, avoiding the trouble of subsequent special treatment, and thus simplifying the production process and improving production efficiency.

[0022] In some embodiments, the sandblasting device includes a sandblasting unit for sandblasting the inner surface of the pot.

[0023] In these embodiments, a sandblasting unit is provided. The sandblasting unit sprays sandblasting material onto the inner surface of the pot. On the one hand, it can remove dirt, oxide layer, etc., and on the other hand, it can provide better adhesion for subsequent coating setting. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Furthermore, in the description of examples, when it is deemed that a detailed description of well-known related components or functions will cause an ambiguous interpretation of the present invention, such detailed description will be omitted.

[0047] The following will be combined Figures 2 to 7 To introduce the protective workwear and sandblasting device provided by this application.

[0048] According to an embodiment of the first aspect of the present application, a protective tool is provided, wherein the protective tool is used to protect the cookware 100, specifically, used in the sandblasting process of the inner surface of the cookware 100, such as Figure 2 and Figure 3 As shown, the protective tooling includes a cover body 10 having a cover cavity 30, and the cover body 10 is used to cover the outer periphery of the cookware 100 so that the cookware 100 is arranged in the cover cavity 30, and a sealed cavity 40 is formed between the cover body 10 and the cookware 100, and a vent hole 121 is opened on the cover body 10 so that the sealed cavity 40 is connected to the outside.

[0049] In the embodiment of the present application, the vent 121 is a vacuum vent, which is connected to the vacuum suction cup 200 of the vacuum equipment to vacuum the sealed cavity 40, thereby adsorbing the cookware 100 in the cover cavity 30.

[0050] In the embodiment of the present application, the cookware 100 is disposed in the cover cavity 30, but this does not mean that the cookware 100 must be completely placed inside the cover cavity 30. In fact, the description here is broader, meaning that the cookware 100 can be at least partially accommodated in the cover cavity 30. In other words, as long as a portion of the cookware 100 can be covered by the cover body 10 and a sealed cavity 40 is formed between the cover body 10 and the cookware 100, the description of "the cookware 100 is disposed in the cover cavity 30" is satisfied.

[0051] According to the protective tooling provided in the embodiment of the present application, when in use, the cookware 100 can be inverted and the cover body 10 can be placed outside the cookware 100. In this case, the cookware is placed in the cover cavity 30 of the cover body 10. The cover body 10 is provided with a vent 121, which enables the sealed cavity 40 to communicate with the outside. In this way, when the vacuum suction cup 200 of the vacuum equipment is set at the bottom of the cookware, the vacuum suction cup 200 can dock with the vent 121 and can evacuate the sealed cavity 40. When the evacuation reaches a certain level, the cookware 100 can be adsorbed in the cover cavity 30 and suspended. In this way, the cover body 10 can be placed around the periphery of the cookware 100 to protect the outer surface of the cookware, thereby ensuring the quality of the outer surface of the cookware without affecting the sandblasting operation of the inner surface, avoiding the trouble of subsequent processing. In addition, when the operation is completed, the vacuum suction cup 200 of the external vacuum equipment can be deflated to separate from the vent 121. In this case, there is no attraction between the cover body 10 and the pot 100. In this way, the cover body 10 and the pot 100 can be easily separated to facilitate the next manufacturing step.

[0052] In some embodiments, reference Figure 3 The pot 100 has a pot bottom wall and an annular pot side wall connected to the pot bottom wall. The pot bottom wall and the pot side wall enclose the general shape of the pot 100. Figures 2 to 4The cover body 10 includes a cover bottom wall 12 and an annular cover side wall 11 connected to the cover bottom wall 12. The cover side wall 11 is connected to the outer periphery of the cover bottom wall 12 and protrudes from the surface of the cover bottom wall 12. The cover bottom wall 12 and the cover side wall 11 enclose the cover body 10 with a cover cavity 30. The cover body 10 of the protective tooling has a substantially similar shape to the cookware 100. During use, the cookware 100 can be placed in the cover cavity 30, so that the cover body 10 completely covers the outer periphery of the cookware 100, thereby protecting the outer surface of the cookware 100 and reducing the impact of the subsequent sandblasting process on the quality of the outer surface of the cookware 100. In addition, the cover body 10 can be turned upside down on the cookware, so that a sealing ring can be used to seal the contact point between the two.

[0053] In some embodiments, as Figure 4 and Figure 5 As shown, the vent hole 121 is provided on the middle portion of the bottom wall 12 of the cover. Thus, after the protective tooling is installed on the cookware 100, without changing the structure and position of other original equipment, it is possible to ensure that the cookware is normally sucked by the vacuum suction cup during the manufacturing process, making it convenient to take and place.

[0054] According to the present application, the height of the protective tooling is greater than the height of the cookware. Thus, when the protective tooling cover is placed on the cookware, a preset distance exists between the bottom wall 12 of the cover body 10 of the protective tooling and the bottom wall of the cookware 100. For example, the preset distance can be 3 mm to 20 mm. It should be noted that the preset distance can be set specifically based on actual conditions to accommodate the height of the cookware. Furthermore, the preset distance can be set larger to accommodate cookware of varying heights. This ensures the versatility of the protective tooling and expands its scope of application.

[0055] In some examples, the protective tooling also includes a sealing strip 20, which is provided on the side wall 11 of the cover and is used to seal and contact the outer surface of the side wall of the pot 100. Exemplarily, the sealing strip 20 can be formed into a ring structure by splicing multiple arc strips. In order to improve the sealing performance, in some embodiments, the sealing strip 20 can be formed into a ring as a whole. According to the present application, the sealing strip 20 can be made of a soft and elastic material, such as rubber or silicone, so as to have a certain elasticity and sealing performance. Figure 6 and Figure 7 As shown, the sealing strip 20 may be formed as a whole in a ring shape.

[0056] In these embodiments, the sealing strip 20 can be provided on the cover side wall 11 of the cover body 10, and is used to make sealing contact with the outer surface of the pot side wall of the cookware 100. When the cover body 10 of the protective tooling and the cookware 100 are assembled together, the sealing strip 20 fits tightly against the outer surface of the pot side wall of the cookware 100, effectively closing the gap between the cover side wall 11 and the pot side wall, thereby ensuring the sealing of the connection between the cover body 10 and the cookware 100. In this case, on the one hand, it can at least prevent sand or other impurities from entering the internal space of the protective tooling, thereby avoiding affecting the quality of the outer surface of the cookware; on the other hand, when air is inhaled through the vent hole 121, it is conducive to forming vacuum adsorption between the cover body 10 and the cookware 100, thereby ensuring the reliability of the connection between the two.

[0057] According to the present application, the sealing strip 20 is provided on the cover side wall 11 , wherein the sealing strip can be provided on the cover side wall 11 through an existing connection form, for example, can be fixed on the cover side wall 11 by bonding.

[0058] According to some embodiments of the present application, the cover sidewall 11 is provided with an annular groove 111, into which the sealing strip 20 is embedded. This allows the sealing strip 20 to fit tightly with the cover body 10 and form an effective seal between the cookware and the cover body. This prevents sand, gas, or other impurities from entering the interior space of the protective workwear. Furthermore, by embedding the sealing strip 20 in the groove 111, the sealing strip can be removably secured to the cover sidewall 11, providing a consistent seal.

[0059] As an example, the sealing strip can be arranged to adapt to the shape of the embedding groove 111. For example, the sealing strip can be annular and inserted into the embedding groove 111 so that the sealing strip 20 has an interference fit with the embedding groove 111 to ensure that the sealing strip 20 is firmly fixed in the embedding groove 111. In this way, a circumferential seal (a complete and continuous seal in the circumferential direction) can be formed between the cover side wall 11 and the pot side wall to enhance the sealing effect.

[0060] In these embodiments, the sealing strip 20 is embedded in the annular embedding groove 111, which provides a fixed installation position for the sealing strip 20, ensuring that the sealing strip 20 is not easily moved during use. In addition, the sealing strip is detachably fixed to the cover sidewall 11, which allows for easy replacement and ensures a good sealing effect during long-term use.

[0061] According to an embodiment of the present application, the sealing strip 20 can be disposed on the inner surface of the cover sidewall 11 near the opening of the cover body 10, or on the end surface of the cover sidewall 11. The end surface of the cover sidewall 11 is the end surface of the cover sidewall 11 of the protective tooling extending to the opening of the cover body 10. For example, the bezel 111 can be provided on the inner wall surface or end surface of the cover sidewall 11 of the protective tooling. If the bezel 111 is provided on the inner wall surface of the cover sidewall 11 of the protective tooling, the sealing strip 20 is embedded in the bezel 111, contacting the pot sidewall of the cookware 100 and forming a seal. If the pot sidewall at the opening of the cookware 100 has an outer flange 120, the bezel 111 can be provided on the end surface of the cover sidewall 11 of the protective tooling, so that the installation position of the sealing strip 20 corresponds to the outer flange 120 of the pot sidewall of the cookware. In this way, when the protective tooling is used, the outer flange 120 can abut against the sealing strip 20.

[0062] In these embodiments, a recess 111 is formed on the end surface of the cover sidewall 11 of the protective tooling, and a sealing strip 20 is disposed within the recess 111. During use, the cookware 100 can be inverted and the cover 10 placed upside down on the cookware 100. At this point, the sealing strip 20 abuts against the outer flange of the cookware and can initially engage under external pressure. After reaching the vacuum equipment, air within the sealed cavity 40 is extracted through the vent 121. During the vacuuming process, a vacuum is formed between the cover 10 and the cookware 100, thereby adsorbing the cookware 100 within the cover cavity 30 to suspend it, allowing sandblasting of the inner surface of the cookware. During the sandblasting process, because the cover 10 can cover the entire periphery of the cookware 100, the outer surface of the cookware is fully protected (preventing it from being sandblasted or scratched), thereby ensuring the quality of the outer surface of the cookware without affecting the sandblasting operation of the inner surface.

[0063] In some embodiments, the cover body 10 is made of nylon material. Therefore, the cover body 10 has good wear resistance and corrosion resistance, and can maintain good performance during long-term use. In addition, this type of cover body 10 has good high temperature resistance, is suitable for withstanding high temperature environments in subsequent sandblasting processes, and meets the requirements of subsequent processes. In addition, nylon material is light in weight and can be easily adsorbed by vacuum equipment. The sealing strip 20 is a silicone foam sealing strip. The silicone foam sealing strip is made of silicone material and has a foaming structure. The silicone foam sealing strip has good softness and elasticity, and can adapt to the combination of different shapes and surfaces, thereby providing good sealing performance.

[0064] In these embodiments, by properly selecting the manufacturing material of the cover body 10 and using a silicone foam sealing strip, better sealing performance and adaptability can be provided, thereby ensuring the effective operation of the protective tooling and protecting the quality of the outer surface of the cookware.

[0065] In some embodiments, the height of the sealing strip 20 above the bezel 111 is within a range of 1 mm to 1.5 mm. Specifically, the height of the sealing strip 20 above the notch of the bezel 111 is within a range of 1 mm to 1.5 mm. It should be noted that the specific height of the sealing strip above the bezel 111 can be adjusted based on actual requirements and design needs.

[0066] In these embodiments, by arranging the sealing strip 20 to be higher than a certain height in the embedding groove 111, the raised portion can provide additional deformation space. In this way, when the protective tooling and the cookware are assembled together, the sealing strip 20 is easy to deform and better adapt to the shape of the side wall of the cookware 100 and / or the surface unevenness, thereby achieving a tight fit and ensuring the sealing performance of the connection. On the one hand, it helps to prevent sand, gas or other impurities from entering the internal space of the protective tooling, thereby ensuring the quality of the outer surface of the cookware. On the other hand, when air is inhaled through the vent hole, it is conducive to forming a vacuum adsorption between the cover and the cookware, thereby ensuring the reliability of the connection between the two.

[0067] In order to connect the pot body 302 with the handle, a spot welding piece 304 is usually provided on the outer surface of the pot body 302. In the prior art, the spot welding piece 304 on the pot body 302 cannot be completely fitted with the pot body 302, and there is usually a gap of 0.1mm-0.3mm. During sandblasting, sand will be sprayed into the gap, resulting in the need for subsequent processing. Specifically, the subsequent processing method can be a sand vibration operation, however, this will lead to an increase in the process, an increase in cost, and affect production efficiency. Another subsequent processing method is to partially apply tape to the spot welding piece 304 in advance, and then perform sandblasting. However, this method requires operations such as applying and tearing off the tape, and there are still problems of increased cost and reduced production efficiency.

[0068] According to the present application, a welding piece 110 for connecting the pot handle is provided on the outer surface of the pot side wall. When the protective tooling is assembled with the pot, the pot 100 can be set in the cover cavity 30, and the cover side wall 11 can be covered on the outside of the welding piece 110.

[0069] In these embodiments, when the cookware 100 is placed in the cover cavity 30, the cover sidewall 11 is provided around the outer periphery of the cookware and covers the outside of the welding piece 110. This not only ensures the surface quality of the cookware, but also provides local protection for the welding piece 110. By eliminating subsequent processing steps and simplifying the production process, manufacturing costs can be greatly reduced and production efficiency can be improved.

[0070] According to the second aspect of the present application, a sandblasting device is provided, wherein the sandblasting device includes a vacuum device and the protective tooling provided according to the above-mentioned embodiments, the vacuum device includes a vacuum suction cup 200, and the vacuum suction cup 200 can be docked with the vent 121 to evacuate the sealed cavity 40, thereby adsorbing the pot 100 in the cover cavity 30.

[0071] According to the sandblasting device provided in the embodiment of the present application, when in use, the cookware 100 can be inverted and the cover body 10 is placed on the outside of the cookware 100. In this case, the cookware is placed in the cover cavity 30 of the cover body 10. The cover body 10 is provided with a vent 121, which enables the sealed cavity 40 to communicate with the outside. In this way, when the cookware passes through the vacuum suction cup 200 of the vacuum equipment during the manufacturing process, the vacuum suction cup 200 can dock with the vent 121 and can evacuate the sealed cavity 40. When the vacuum is evacuated to a certain degree, the cookware 100 can be adsorbed in the cover cavity 30 and suspended to facilitate sandblasting of the inside of the cookware. In this way, the cover body 10 can be placed on the periphery of the cookware 100 to protect the outer surface of the cookware, thereby ensuring the quality of the outer surface of the cookware without affecting the sandblasting operation of the inner surface, avoiding the trouble of subsequent processing. In addition, after the sandblasting operation is completed, the vacuum suction cup 200 of the external vacuum equipment can be deflated to separate from the vent 121. In this case, there is no attraction between the cover body 10 and the pot 100. In this way, the cover body 10 and the pot 100 can be easily separated to facilitate the next manufacturing step.

[0072] In some embodiments, the sandblasting apparatus includes a sandblasting unit for sandblasting the inner surface of the cookware 100. The sandblasting unit is a device or component for performing the sandblasting process. In an exemplary embodiment, the sandblasting unit may include components such as a sandblasting gun, a sandblasting nozzle, a sandblasting material supply system, and a control system. The locations and connections of these components may be arranged using existing configurations.
