Description

Technical Field

[0001] This utility model belongs to the field of kitchen utensils manufacturing, specifically relating to an automatic iron pot seasoning device. Background Technology

[0002] In the kitchenware manufacturing industry, cast iron pots are durable, uncoated, safe to use, and relatively easy to clean, thus maintaining a strong position in the cookware market. However, due to cost control, production efficiency, and product standardization requirements, most cookware manufacturers do not perform seasoning before their products leave the factory. Currently, users must season the pots themselves after purchase. However, improper seasoning can easily damage the coating and cause rust, affecting the lifespan and safety of the pot. Furthermore, the process is cumbersome and unfriendly to novice cooks, potentially leading to a less than ideal user experience due to inconvenience or mistakes. As consumers increasingly demand higher quality and ease of use for their cookware, if manufacturers could adopt automated seasoning technology to mass-produce professionally pre-treated cast iron pots in a standardized manner, they could not only solve the problem of users having to season the pots themselves but also ensure product performance through a stable, efficient, and standardized pre-treatment process. This advantage would not only enhance the user experience but also create a unique selling point through differentiated competition, thereby improving the market competitiveness of the company's cast iron pot products.

[0003] Therefore, developing a device that can automate, optimize, and standardize the boiling process is key to solving the above problems. Utility Model Content

[0031] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0032] In the accompanying drawings, to more clearly illustrate the structure of this utility model, only the oil delivery hose connection relationship corresponding to one set of lifting oil brushing mechanisms is shown; the oil delivery hose corresponding to the other set of lifting oil brushing mechanisms is not shown. Furthermore, only the iron pot corresponding to one set of pot-shaped grooves is shown; the iron pot corresponding to the other set of pot-shaped grooves is not shown, for example... Figure 3 As shown: the iron pot 1 above one row of pot-shaped grooves 22 and the oil delivery hose 314 corresponding to the lifting oil brushing mechanism 4 above it have been shown; the iron pot 1 above the other row of pot-shaped grooves 22 and the oil delivery hose 314 corresponding to the lifting oil brushing mechanism 4 above it are not shown; the dimensions and proportions of the oil delivery hose 314 and each component shown in the figure are for illustrative purposes only.

[0033] like Figure 1-12As shown, the technical solution adopted by this utility model is: an automatic iron pot seasoning device, including an iron pot 1, a heating mechanism 2, and an oil conveying mechanism 3, wherein the heating mechanism 2 includes a base 21, and two rows of pot-shaped grooves 22 are provided above the base 21; the automatic iron pot seasoning device also includes two sets of identical lifting and brushing oil mechanisms 4 disposed above the heating mechanism 2, the lifting and brushing oil mechanism 4 including two identical linear modules 41 respectively disposed at both ends of the length direction of the heating mechanism 2, each linear module 41 including a slider 411 that can move vertically, and a support rod 42 that moves with the slider 411 is provided between the two identical linear modules 41. Here, the sliders included in each set of linear modules 41 Under the control of PLC controller 5, the vertical movement frequency and distance of 411 are synchronized to ensure that the horizontal position is the same during movement, thereby ensuring the stability of the support rod 42 that moves with the slider 411. The support rod 42 is equipped with servo motors 43 in number and position corresponding to the pot-shaped groove 22. The output shaft of the servo motor 43 is connected to a limit connector 44, and the limit connector 44 is connected to an elastic composite brush plate 45. Here, PLC controller 5 controls the servo motor 43 through signal lines, so that its output shaft can perform reciprocating rotation, thereby driving the limit connector 44 and the elastic composite brush plate 45 below the output shaft of the servo motor 43 to perform reciprocating rotation.The basic working principle of the above setup is as follows: First, the PLC controller 5 controls the heating mechanism 2 to preheat the iron pot 1 above one of the rows of pot-shaped grooves 22 above the base 21 for 1-3 minutes, and then stops heating. Then, the PLC controller 5 controls the linear module 41 of a set of lifting and brushing mechanisms 4 above the row of iron pots 1, so that the slider 411 in the linear module 41 moves downward, thereby driving the support rod 42 that moves with the slider 411 to move downward. The number and position of the servo motors 43 installed on the support rods 42 are all corresponding to the pot-shaped grooves 22. The limit connector 44 is connected below the output shaft of the servo motor 43. The elastic composite brush plate 45 connected below moves downwards until its bottom contacts the surface of the iron pot 1. The movement distance and start / stop are controlled by the linear module 41 via the PLC controller 5, which is existing technology and will not be elaborated further. After the bottom of the elastic composite brush plate 45 contacts the surface of the iron pot 1, the oil conveying mechanism 3 delivers grease into the oil trough 453 of the elastic composite brush plate 45. Then, the PLC controller 5 controls the servo motor 43 via signal control lines, causing its output shaft to reciprocate. The limit connector 44 is connected below the output shaft of the servo motor 43, and the elastic brush plate 45 is connected below the limit connector 44... The elastic composite brush plate 45 reciprocates, and during this reciprocating motion, the grease in the oil groove 453 of the elastic composite brush plate 45 is evenly applied to the surface of the iron pot 1, completing the oiling process. Then, the PLC controller 5 controls the lifting oiling mechanism 4 to return to its original state. The heating mechanism 2 heats the iron pot 1 below the lifting mechanism for 10-20 minutes to complete the boiling process, which takes approximately 13-25 minutes. Halfway through this time, the PLC controller 5 controls the iron pot 1 above the iron pot-shaped groove 22 on the other row of bases 21 and its corresponding lifting oiling mechanism 4 to perform the same process. The purpose of the pot-opening operation is that the two sets of lifting and oiling mechanisms 4 work alternately to effectively utilize the heating time required for pot opening. During this period, the operator can control the equipment, place the iron pot 1 in the heating position, or remove the iron pot 1 after heating is complete. In short, the time is effectively utilized to ensure production efficiency. In addition, since the equipment is highly automated, only one operator is needed for one automatic iron pot opening device of this utility model. In the above, the servo motor 43 is the prior art. Its output shaft can achieve reciprocating rotation under the control of the PLC controller 5. In this embodiment, the reciprocating rotation angle of the output shaft of the servo motor 43 is 90°.

[0034] The limiting connector 44 includes a coupling 441, a limiting plate 442, a threaded connecting post 443, and a notch 444. The coupling 441 is connected to the output shaft of the servo motor 43. The coupling 441 is a cylindrical structure without a top cover. The output shaft of the servo motor 43 and the coupling 441 can be connected by a key. The limiting plate 442 is integrally located below the coupling 441. The threaded connecting post 443, integrally located below the limiting plate 442, is located in the center below the limiting plate 442. Notches 444 are evenly distributed around the circumference of the limiting plate 442. The function of the limiting connector 44 is to connect the servo motor 43 and the elastic composite brush plate 45, so that the rotation of the output shaft of the servo motor 43 drives the elastic composite brush plate 45. The composite brush plate 45 rotates accordingly. Secondly, because the elastic composite brush plate 45 is elastic, when the elastic composite brush plate 45 contacts the iron pot 1 to brush oil, the elastic composite brush plate 45 will deform due to the upward supporting force of the iron pot 1. This may cause the elastic composite brush plate 45 to not fully contact the surface of the iron pot 1, resulting in uneven oil brushing. When this equipment is working, the limiting plate 442, which is integrated with the coupling joint 441, is set below the coupling joint 441. The lower end of the limiting plate 442 abuts against the upper end of the elastic composite brush plate 45. When the elastic composite brush plate 45 deforms upward, the limiting plate 442 will limit the elastic composite brush plate 45, forcing the hemispherical surface below the elastic composite brush plate 45 to adhere tightly to the surface of the iron pot 1, so that the oil brushing is even.

[0035] The elastic composite brush plate 45 includes a plate body 451, a threaded connection hole 452 at the center of the upper end of the plate body 451, and an oil-draining groove 453 circumferentially formed on the plate body 451. The threaded connection hole 452 is connected to a threaded connection post 443. The upper opening of the oil-draining groove 453 corresponds sequentially to the notch 444 circumferentially formed on the limiting plate 442. The elastic composite brush plate 45 can be made of composite silicone rubber, which has the characteristics of high temperature resistance, good elasticity, safety and non-toxicity. It is very suitable as the material for the elastic composite brush plate 45 in the iron pot seasoning equipment, which can meet the needs of use in high temperature environment and ensure the safety and efficiency of the oil brushing process. The upper opening of the oil-draining groove 453 corresponds sequentially to the notch 444 circumferentially formed on the limiting plate 442. This setting ensures the accuracy of oil delivery and is conducive to the scientific rationality and practicality of this utility model.

[0036] A ceramic layer 23 is laid on top of each pot-shaped groove 22. A spiral partition 231 is provided on the inner surface of the ceramic layer 23. An electric heating wire 232 is laid between the spiral partitions 231. A microcrystalline panel 24 is provided above the electric heating wire 232. The iron pot 1 is placed on the microcrystalline panel 24. In this arrangement, the ceramic layer 23 above the pot-shaped groove 22 has high temperature resistance and heat insulation properties. It not only provides installation support for the spiral partitions 231 and the electric heating wire 232, but also reduces the heat conduction to the base 21. The spiral partitions 231 fix the electric heating wire 232 in a spiral layout, making its heat radiation more uniform. The heat generated by the electric heating wire 232 is evenly transferred to the iron pot 1 through the microcrystalline panel 24. Its flat surface can also stably support the iron pot 1. The entire structure controls the power parameters of the electric heating wire 232 through the PLC controller 5 to achieve precise control of the heating temperature and uniformity of the iron pot 1, providing a stable heat source for the boiling process.

[0037] The two rows of pot-shaped grooves 22 above the base 21 correspond vertically to the two sets of lifting and brushing mechanisms 4. This arrangement ensures that the elastic composite brush 45 driven by each set of lifting and brushing mechanisms 4 is vertically aligned with the iron pot 1 on the pot-shaped groove 22 below, thus ensuring accurate positioning during brushing and preventing deviation. At the same time, by utilizing the correspondence between the two rows of pot-shaped grooves 22 and the two sets of lifting and brushing mechanisms 4, a production line operation of alternating preheating, brushing, and heating can be realized. While one set of iron pots 1 is being heated and opened in the pot-shaped groove 22, the other set can simultaneously perform preheating or brushing operations in the corresponding pot-shaped groove 22, effectively utilizing the heating time, reducing equipment idle time, thereby improving overall production efficiency and ensuring the continuity and efficiency of the automated process.

[0038] The limiting connector 44 also includes a hose mounting hole 445 disposed above the notch 444; this configuration provides a standardized installation interface for the oil delivery hose 314, so that the grease output by the oil delivery mechanism 3 can be precisely connected to the notch 444 through the oil delivery hose 314 and then flow into the oil trough 453 of the elastic composite brush 45; at the same time, it facilitates the quick disassembly and maintenance of the hose, improves the convenience of equipment operation and maintenance, and is beneficial to the practicality of this utility model.

[0039] The oil delivery mechanism 3 includes an oil storage tank 31, a first oil outlet 32, a first oil delivery main pipe 33, an oil inlet 34, a gear oil pump 35, a second oil outlet 36, a second oil delivery main pipe 37, and a motor 38. The oil storage tank 31 is connected to the first oil delivery main pipe 33 via the first oil outlet 32. The first oil delivery main pipe 33 is connected to the gear oil pump 35 via the oil inlet 34. The gear oil pump 35 is connected to the second oil delivery main pipe 37 via the second oil outlet 36. The output shaft of the motor 38 is connected to the gear oil pump 38 via a coupling. 5. The output shaft provides the power for pumping oil. This setting is designed to provide a continuous and stable supply of grease for the brushing operation. The principle is as follows: the motor 38 drives the gear oil pump 35 through the coupling. The gear oil pump 35 pumps the grease out of the oil storage tank 31. The grease flows into the first oil supply main pipe 33 through the first oil outlet 32, and then enters the gear oil pump 35 through the oil inlet 34. After being pressurized by the gear oil pump 35, the grease enters the second oil supply main pipe 37 through the second oil outlet 36, and is finally delivered to the subsequent oil supply components.

[0040] The oil delivery mechanism 3 also includes a three-way connector 39, a solenoid valve 310, oil delivery branch pipes 311, a five-way connector 313, an oil delivery hose 314, and a pipe support frame 315. The pipe support frame 315 is positioned above the base 21, with its lateral position at the center-to-center distance between the two sets of lifting and brushing mechanisms 4. A channel 316 is formed along the length of the upper part of the pipe support frame 315, and two oil delivery branch pipes 311 are laid along the length of the channel 316. Each of these two oil delivery branch pipes 311 is connected to a solenoid valve 310 at one end near the second main oil delivery pipe 37. The other end of the solenoid valve 310 is connected to a branch outlet of the three-way connector 39, and the inlet of the three-way connector 39 is connected to the second main oil delivery pipe 37. This arrangement allows a single gear oil pump 35 to alternately supply oil to the two sets of lifting and brushing mechanisms 4. Note that the length of the oil delivery hose 314 should meet the range of motion of the lifting and brushing mechanism 4. The principle is that the pipe support frame 315 passes through the center-to-center distance... The positioning ensures that the oil supply branch pipe 311 corresponds symmetrically with the two sets of oil brushing mechanisms. The oil supply branch pipe 311 in the channel 316 is connected to the second oil supply main pipe 37 via the solenoid valve 310 and the three-way connector 39. When the PLC controls one of the solenoid valves 310 to open, the grease output by the gear oil pump 35 is diverted to the corresponding oil supply branch pipe 311 via the three-way connector 39, and then delivered to the hose mounting hole 445 of the limit connector 44 via the five-way connector 313 and the oil supply hose 314. Meanwhile, the other solenoid valve 310 is closed under the control of the PLC, blocking the oil circuit corresponding to the solenoid valve 310 and preventing grease from mixing. This design, through the on / off logic of the solenoid valve 310 and the diversion structure of the three-way connector 39, combined with the alternating action of the two sets of lifting oil brushing mechanisms 4, realizes the time-sharing oil supply of a single gear oil pump 35, which not only saves hardware costs, but also ensures the positioning accuracy of the oil circuit through the rigid layout of the pipeline support frame 315, ensuring that the grease is accurately delivered as needed.

[0041] The channel 316, extending along the length of the pipe support frame 315, has through holes 317, the same number and corresponding in position as the servo motors 43, on its inner wall along the width direction. A branch pipe 311 is connected above a diversion bend 312, the same number and corresponding in position as the through holes 317. The horizontal portion of the diversion bend 312 extends outward from the through holes 317, and each outwardly extending outlet end of the diversion bend 312 is connected to a five-way connector 313. The branch outlet ends of the five-way connector 313 are respectively connected to oil delivery hoses. Pipe 314 is connected to hose mounting hole 445; the purpose of this setting is to construct a complete grease distribution network to ensure that grease is accurately delivered from oil supply branch pipe 311 to each elastic composite brush plate 45. The principle is to form a complete oil circuit of "oil supply branch pipe 311 → diversion bend pipe 312 → five-way connector 313 → oil supply hose 314 → hose mounting hole 445 → notch 444 → oil trough 453", which meets the grease supply needs when the two sets of lifting brushing mechanisms 4 work alternately, and ensures the continuity and stability of the entire boiling process.

[0042] The linear module 41 is a lead screw type linear module. The linear module 41 adopts a lead screw structure, which has the advantages of having a certain load capacity and acceptable movement accuracy, making it suitable for the application scenarios of this equipment. In this embodiment, the movement of the slider 411 in the linear module 41 is achieved by the PLC controller 5 controlling the signal line of the linear module 41, which is existing technology and will not be elaborated further.

[0043] The elastic composite brush plate 45 has a hemispherical shape with a horizontal end face. The oil channel 453 extends from the horizontal end face along the hemispherical surface to the bottom of the hemispherical surface. This design achieves uniform oiling by adapting the hemispherical surface to the arc-shaped inner wall of the iron pot 1. The advantage is that the hemispherical shape can closely fit the curved surface of the pot body to eliminate blind spots in oiling. The oil channel 453 is opened along the oil guide path of the hemispherical surface, so that the grease flows evenly from the top oil inlet to the surface of the pot body. This ensures that when the output shaft of the servo motor 43 drives the limit connector 44 connected below it and the elastic composite brush plate 45 connected below the limit connector 44 to perform reciprocating rotation, the grease is evenly coated on the surface of the iron pot 1 from the horizontal direction. The horizontal end face abuts against the limit plate 442 to limit excessive deformation of the brush plate to ensure the contact pressure.

[0044] The automatic hot pot opening device includes a PLC controller 5; its function is to realize the full-process automatic control of the equipment through a preset program, such as controlling the on and off of the heating element 232 of the heating mechanism 2 to adjust the heating temperature and time, driving the screw linear module 41 to realize the precise displacement of the lifting and brushing mechanism 4, controlling the start and stop of the gear oil pump 35 and the on and off of the solenoid valve 310 to adjust the oil delivery, and coordinating the alternating operation logic of the two sets of lifting and brushing mechanisms 4.

[0045] Specific working principle: The PLC controller 5 first controls the heating wire 232 between the spiral baffles 231 in the ceramic layer 23 of the pot-shaped groove 22 above the base 21 of the heating mechanism 2 to be energized. The microcrystalline panel 24 preheats one row of iron pots 1 for 1-3 minutes. Then, it controls the linear module 41 slider 411 of one set of lifting oil brushing mechanism 4 above the row of iron pots 1 to move down synchronously, driving the servo motor 43, limit connector 44 and elastic composite brush 45 on the support rod 42 to descend to contact the iron pot 1. The oil conveying mechanism 3 sequentially conveys the oil through the oil storage tank 31, the first oil outlet 32, the first oil conveying main pipe 33, the oil inlet 34, the gear oil pump 35, the second oil outlet 36, the second oil conveying main pipe 37, the tee connector 39, the solenoid valve 310, the oil conveying branch pipe 311, the pipe support frame 315, the diversion bend 312, the five-way connector 313 and the oil conveying hose 314. The hose is inserted into the oil trough 453 of the elastic composite brush plate 45 through the mounting hole 445 and notch 444. Then, the PLC controller 5 controls the output shaft of the servo motor 43 to rotate back and forth, driving the elastic composite brush plate 45 to evenly apply the grease. After brushing, the lifting mechanism resets, and the heating mechanism 2 heats the iron pot 1 for 10-20 minutes to complete the boiling process. When the process is halfway through, the PLC controller 5 controls another row of pot-shaped grooves 22 to start the same process synchronously with the corresponding lifting and brushing mechanism 4. During this period, the operator can put the iron pot 1 into the pot-shaped groove 22 or take out the heated iron pot 1 when the two sets of mechanisms are working alternately. Through the vertical corresponding layout of the two rows of pot-shaped grooves 22 and the two sets of lifting and brushing mechanisms 4, the oil supply mechanism 3 realizes the time-sharing oil supply through the on / off logic and diversion structure of components such as the three-way connector 39, solenoid valve 310, and oil supply branch pipe 311, and finally realizes the alternating operation of this utility model.
