Description

Technical Field

[0001] This utility model provides a cleaning device for the production of stainless steel tableware, belonging to the technical field of cleaning devices. Background Technology

[0002] Stainless steel tableware is widely used in the catering industry and households due to its advantages such as corrosion resistance, easy cleaning, and aesthetic appeal. During the manufacturing process of stainless steel tableware, such as knives, forks, and spoons with handles, after multiple processes including stamping, stretching, and polishing, a large amount of oil, polishing wax, metal shavings, and other contaminants remain on the surface. Thorough cleaning is essential before it can proceed to the subsequent packaging or sterilization stages.

[0003] Currently, most equipment on the market for cleaning stainless steel tableware uses ultrasonic cleaning technology. This technology utilizes the "cavitation effect" generated by ultrasound in a liquid, forming countless tiny bubbles that burst instantly, generating a powerful impact force that peels off dirt from the surface of the workpiece. A typical ultrasonic cleaning device usually includes a cleaning chamber, an ultrasonic transducer located at the bottom of the cleaning chamber, and a mesh basket for holding the tableware.

[0004] However, in-depth research has revealed several significant shortcomings in existing technologies: Traditional cleaning methods typically involve stacking or haphazardly placing large quantities of tableware, such as knives, forks, and spoons, in ordinary mesh baskets for washing. This method easily leads to overlap and tight contact between the tableware, creating numerous cleaning blind spots. Consequently, ultrasonic energy cannot be evenly applied to all surfaces of each piece of tableware, resulting in incomplete cleaning and uneven cleanliness. Furthermore, most cleaning methods rely on manual labor to slowly place and remove the heavy mesh baskets filled with tableware from the cleaning chamber, which is time-consuming, labor-intensive, and requires hand-draining, leading to high labor intensity. Therefore, this invention provides a cleaning device for the production of stainless steel tableware. Utility Model Content

[0005] The technical problem solved by this utility model is that when a large number of tableware are stacked or scattered in ordinary mesh baskets for washing, blind spots are easily formed between the tableware, resulting in incomplete cleaning and uneven cleanliness. In addition, it relies on manual labor to put the heavy mesh basket full of tableware into and take it out of the washing chamber. Putting and taking out the mesh basket is relatively time-consuming and laborious, and it is necessary to drain the water by hand, which is labor-intensive.

[0006] To solve the technical problem, the technical solution provided by this utility model is as follows: a cleaning device for stainless steel tableware production, including a housing, a cleaning chamber inside the housing, an ultrasonic component at the bottom of the cleaning chamber, and further comprising: A tableware rack includes a stepped support rod, wherein a plurality of placement arms are equidistantly arranged on the upper circumference of the stepped support rod, and each placement arm has an open clamping groove on its two opposite sidewalls for limiting the tableware. A lifting assembly for raising and lowering a tableware rack includes a horizontal plate, a rectangular frame at the top of the horizontal plate, a slider slidably connected inside the rectangular frame, a driving part on the rectangular frame for driving the slider to rise and fall, and two placement arms on the side walls of the slider, positioned above the cleaning chamber. The ends of the placement arms are provided with open clamping grooves for limiting the step support rods.

[0007] Furthermore, the driving unit includes a motor fixedly mounted on the top of the rectangular frame, the output end of the motor being fixedly connected to a screw threadedly connected to the slider, and the other end of the screw being rotatably connected to the bottom of the rectangular frame.

[0008] Furthermore, the horizontal plate is fixedly installed in the middle of the top of the machine casing and placed above the cleaning chamber, and the lower part of the two side walls of the rectangular frame is provided with reinforcing plates that are fixedly connected to the top of the horizontal plate.

[0009] Furthermore, the ultrasonic component includes at least one ultrasonic generator and several ultrasonic transducers fixed to the bottom of the cleaning chamber. The ultrasonic transducers are used to convert high-frequency electrical signals into high-frequency mechanical oscillations to act on the cleaning fluid.

[0010] Furthermore, the stepped support rod includes a top head, a middle rod, and a bottom rod integrally formed from top to bottom. The diameter of the top head is larger than that of the middle rod, the diameter of the middle rod is larger than that of the bottom rod, the placement arm is fixedly mounted on the body of the bottom rod, and the bottom of the bottom rod is provided with a hollow support.

[0011] Furthermore, the inner wall of the first open clamping groove is provided with a first gathering pad that is interference-fitted with stainless steel tableware, and the inner wall of the second open clamping groove is provided with a second gathering pad that is interference-fitted with the stepped support rod.

[0012] The beneficial effects of this utility model are: The tableware rack is filled with stainless steel tableware that is confined within the opening slot, effectively preventing blind spots in cleaning between tableware. This allows ultrasonic energy to be applied evenly to the surface of each tableware, resulting in thorough and uniform cleaning. The tableware rack filled with stainless steel tableware is electrically placed into and removed from the cleaning chamber via a lifting component. Removing and placing the basket is time-saving and labor-saving, and there is no need to drain the water by hand, effectively reducing labor intensity and improving the cleaning quality of stainless steel tableware.

[0018] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0019] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] Example: According to the appendix Figure 1As shown: This utility model provides a cleaning device for stainless steel tableware production, including a housing 1, which is the overall frame of the device. The housing 1 is typically made of high-quality stainless steel (such as SUS304) sheet metal, with a polished surface for aesthetic appeal and easy cleaning. The housing 1 contains a cleaning chamber 2, which is the core area for holding the cleaning solution and performing ultrasonic cleaning. Its inner wall material is preferably SUS316 stainless steel, which has stronger resistance to acid and alkali corrosion, to accommodate different cleaning solution formulations. The cleaning chamber 2 is also equipped with an inlet, drain valve, heater, and temperature sensor (not shown in the figure) to control the injection and discharge of the cleaning solution and to precisely maintain the temperature at a set value. This is a known and mature technology and will not be described in detail here. An ultrasonic component is located at the bottom of the cleaning chamber 2, and the ultrasonic component includes at least one ultrasonic wave... The device consists of a generator and several ultrasonic transducers fixed to the bottom of the cleaning chamber. The transducers are electrically connected to an external ultrasonic generator, together forming an ultrasonic component. The ultrasonic transducers convert high-frequency electrical signals into high-frequency mechanical oscillations to act on the cleaning fluid. Existing technology can be used for the ultrasonic component. The preferred operating frequency of the ultrasonic component is 28kHz or 40kHz, because lower frequencies can generate larger cavitation bubbles and stronger impact force, which is suitable for removing stubborn oil stains and polishing wax from stainless steel surfaces. This is a known and mature technology and is the core part of realizing the ultrasonic cleaning function. It removes dirt by generating a strong cavitation effect, which will not be elaborated on here. This device is used with a special ultrasonic cleaning fluid. For oil stains and polishing paste commonly found in the production of stainless steel tableware, a food-grade water-based alkaline cleaning agent is recommended.

[0022] This embodiment also includes: As per the instruction manual Figure 1 , 2As shown in Figure 3: The tableware rack 3 includes a stepped support rod 4. Several placement arms 5 are equidistantly arranged on the upper circumference of the stepped support rod 4. Each placement arm 5 has an open clamping groove 6 on its two opposite side walls for positioning tableware. The inner wall of the open clamping groove 6 is provided with a retaining pad 20 that is interference-fitted with the stainless steel tableware. The stepped support rod 4 includes a top head 16, a middle rod 17, and a bottom rod 18 integrally formed from top to bottom. The diameter of the top head 16 is larger than that of the middle rod 17, and the diameter of the middle rod 17 is larger than that of the bottom rod 18. The placement arms 5 are fixedly mounted on the body of the bottom rod 18. The bottom of the bottom rod 18 has a hollow support 19, which ensures the stability of the rack when it is placed on the ground. At the same time, it does not affect the flow of the cleaning solution. Specifically, for stainless steel cutlery with handles such as knives, forks, and spoons, since the upper and lower dimensions of the handles are often different, by first placing the smaller part of the stainless steel cutlery handle into the open clamping groove 6, and then moving the stainless steel cutlery handle up and down, the relatively larger part of the stainless steel cutlery handle is interference-fitted with the retaining pad 20, thereby limiting the stainless steel cutlery with handles such as knives, forks, and spoons within the open clamping groove 6. This design ensures that each piece of cutlery can be independently limited within the open clamping groove 6, ensuring that there is sufficient gap between the cutlery, so that the cleaning solution and ultrasonic waves can reach every surface of the cutlery without obstruction, avoiding cleaning blind spots.

[0023] As per the instruction manual Figure 2 , 4 As shown: The lifting assembly 22 for lifting the tableware rack 3 includes a horizontal plate 7 fixedly installed in the middle of the top of the housing 1 and placed above the cleaning chamber 2. The top of the horizontal plate 7 is provided with a rectangular frame 8. The lower part of the two side walls of the rectangular frame 8 is provided with reinforcing plates 15 fixedly connected to the top of the horizontal plate 7 to strengthen the fixation. A slider 9 is slidably connected inside the rectangular frame 8. The two side walls of the slider 9 are provided with a second placement arm 11 placed above the cleaning chamber 2. The end of the second placement arm 11 is provided with an open clamping groove 12 for limiting the step support rod 4. The inner wall of the open clamping groove 12 is provided with a tightening pad 21 that is interference-fitted with the step support rod 4. Specifically, similar to the limiting method of stainless steel tableware, by first moving the bottom rod 18 of the step support rod 4 into the open clamping groove 12, and then moving the step support rod 4 up and down, the middle rod 17 is interference-fitted with the tightening pad 21 in the open clamping groove 12, and the top head 16 is placed on the top of the second placement arm 11, thereby limiting the step support rod 4 on the second placement arm 11.

[0024] As per the instruction manual Figure 2As shown: The rectangular frame 8 is provided with a driving part 10 for driving the slider 9 to rise and fall. The driving part 10 includes a motor 13 fixedly installed at the top of the rectangular frame 8. The output end of the motor 13 is fixedly connected to a screw 14 threadedly connected to the slider 9. The other end of the screw 14 is rotatably connected to the bottom of the inner side of the rectangular frame 8. The two inner side walls of the rectangular frame 8 are symmetrically provided with limiting rails that match the side walls of the slider 9, which play a role in limiting the slider 9. Specifically, when the motor 13 is started, it drives the screw 14 to rotate. Under the limitation of the limiting rails, the slider 9 is driven to rise and fall.

[0025] Those skilled in the art can understand, based on their own knowledge and common common sense, that the problem of dust and rust on the exposed screw can be solved by regularly cleaning the dust, and by using methods such as galvanizing or coating the screw to prevent rust and increase its service life. When the screw is rusted to the point of being unusable, it can be replaced. As for the problem of the exposed motor, a protective cover can be added for protection. As for the problem of heat dissipation of the motor, heat dissipation can be achieved by installing heat dissipation fins on the outside of the protective cover. The above and other common-sense issues that can be solved based on one's own knowledge and common common sense do not affect the normal use of this case.

[0026] A telescopic screw protective sleeve (such as an accordion cover) can also be installed on the outside of the screw and placed between the rectangular frame and the slider. It is not shown in the figure. The specific structure is existing technology, and the installation method can be obtained based on existing technology.

[0027] As an optional embodiment, the two constriction pads are typically made of high-temperature and corrosion-resistant elastic materials (such as silicone or EPDM rubber). Their function is twofold: firstly, by providing a flexible clamping force through an interference fit, they can limit the cutlery and stepped support rod 4, preventing them from loosening or getting scratched under ultrasonic vibration; secondly, their elasticity can adapt to cutlery handles of different sizes and shapes, enhancing the versatility of the device.

[0028] The control method of this utility model is through a controller, such as the Siemens S7-200 series. The controller adopts existing mature technology, which will not be described in detail here. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0029] The principle of this utility model When using it, the complete work cycle steps are as follows: Loading: The operator places stainless steel cutlery with handles, such as knives, forks, and spoons, into the open clamping groove 6. Then, the operator moves the cutlery rack 3, which is filled with stainless steel cutlery, to the designated position directly above the cleaning chamber 2. The step support rod 4 is placed into the open clamping groove 12 on the placement arm 11. Since the contact area between the stainless steel cutlery and the gathering pad 20 is limited, it effectively avoids the formation of large cleaning blind spots between the cutlery, so that the ultrasonic energy acts on all surfaces of each cutlery, improving the cleanliness of the cleaning. Lowering: The controller starts the motor 13 to rotate forward, which drives the slider 9 to rise and fall, thereby driving the second placement arm 11 and the tableware placement rack 3 to descend at a constant speed until the stainless steel tableware is completely immersed in the cleaning solution in the cleaning chamber 2. Cleaning: Start the ultrasonic components and heater via the controller to begin ultrasonic cleaning. The set cleaning time is, for example, 15 minutes. Lifting and Draining: After the washing time is over, the controller turns off the ultrasonic waves and starts motor 13 to reverse, raising the tableware rack 3 to its initial position at a constant speed. The rack stays above the washing chamber for a preset time (e.g., 1 minute) so that most of the washing liquid drips back into the washing tank. Unloading: After draining, remove the stepped support rod 4 from the open clamping groove 2 12 and move the cleaned tableware rack 3 away. At this point, one work cycle is completed. The subsequent multi-stage rinsing tank and hot air drying tank can be connected for the next rinsing and drying process.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
