Description

Technical Field

[0001] This invention relates to the field of ovens, and in particular to an oven and baking method based on PDA barcode scanning. Background Technology

[0002] During the baking process, operators need to check and compare the baking parameters of the product with the specifications, and manually set the oven's operating temperature and time on the machine. The baking parameters vary for different products, which means that operators need to frequently set the corresponding parameters on the machine according to the product's baking requirements. This poses a significant operational risk, as it is easy to set the wrong parameters. For example, setting the temperature and time above the product's critical values ​​can cause irreversible damage to the product, while setting them too low will not meet the product's requirements. At the same time, operators need to manually record the historical information of the baking batch on the work record sheet for each operation, which increases the workload of the operators and makes the work records less reliable and prone to oversight and errors.

[0003] An oven, as disclosed in Chinese Patent No. CN108852028B, includes a cabinet having a bottom plate, a top plate, a front plate, and a back plate. Two side plates are respectively provided on both sides of the cabinet. The bottom plate, top plate, front plate, back plate, and side plates are detachably connected. A combustion chamber is located on the upper part of the cabinet and below the top plate. This invention's oven uses a detachable cabinet, which is convenient for cleaning. Disassembly reduces volume and transportation costs. After assembly, the structure is stable and safe to use. The igniter in the combustion chamber, in conjunction with the combustion plate, uses natural gas as an energy source, resulting in rapid heating, low energy consumption, adjustable flame settings, and a wide range of applications.

[0004] In existing ovens, because the baking tray is inside the oven, users wearing gloves need to put their hands inside the oven to handle it. However, the internal temperature of the oven is too high, which can easily burn the user's skin. Therefore, to address the above problem, an oven and baking method based on PDA scanning is proposed. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: an oven and baking method based on PDA scanning, comprising an oven body, a supporting leg fixedly connected to the bottom of the oven body, an oven door rotatably connected to one side of the oven body, a pull rod fixedly connected to one side of the oven door, a base plate fixedly connected inside the oven body, a bottom groove at the top of the base plate, an oven rack slidably connected to the top of the base plate, a baking tray slidably connected to the top of the oven rack, a bottom guide strip fixedly connected to the bottom of the oven rack, a bottom roller rotatably connected to the inner wall of the bottom guide strip, heat-resistant rotating shafts installed on both sides of the oven rack, a first transmission rod and a second transmission rod rotatably connected to the inner wall of the heat-resistant rotating shafts respectively, a slider fixedly connected to one side of the heat-resistant rotating shaft, the slider rotatably connected to one end of the pull rod, a groove opened on the inner wall of the second transmission rod, and the slider slidably connected to the inner wall of the second transmission rod.

[0006] Preferably, a toothed plate is fixedly connected to the top of the base plate, a first fixing block is fixedly connected to both sides of the oven rack, a second fixing block is fixedly connected to both sides of the oven rack, and a limit rod is fixedly connected to the top of the first fixing block.

[0007] Preferably, a transmission gear is rotatably connected to the top of the second fixed block, the transmission gear meshes with one side of the rack plate, and a lead screw is fixedly connected to the top of the transmission gear.

[0008] Preferably, the outer wall of the lead screw is threadedly connected to a sliding frame, the sliding frame is slidably connected to the outer wall of the limiting rod, and a pressing body is fixedly connected to one side of the sliding frame.

[0009] Preferably, a telescopic rod is fixedly connected to the inner top wall of the pressing body, and an abutment block is fixedly connected to the bottom of the telescopic rod. The abutment block is slidably connected to the inner surface wall of the pressing body.

[0010] Preferably, the bottom of the abutting block is rotatably connected to an abutting roller, and the abutting block is fixedly connected to a spring via a pressing body.

[0011] Preferably, a double-layered transparent glass is fixedly connected to one side of the oven door, and a heat-insulating handle is fixedly connected to one side of the oven door.

[0012] Preferably, a control center is installed on one side of the oven body, and an adjustment knob is installed on the other side of the oven body.

[0013] A baking method comprising the following steps: S1: PDA terminal: Equipped with a barcode scanning module and a wireless communication module, used to collect batch barcode information; S2: MES server: Stores a database of product baking parameters and matches batch numbers with preset parameters via SQL queries; S3: Oven controller: Integrated Modbus TCP protocol communication interface, receives RS signal conversion instructions from MES; S4: Data logging module: Uses a MySQL database to store operation logs in real time, including fields such as timestamp, operator ID, batch number, and set parameters.

[0014] In summary, this invention provides an oven and baking method based on PDA barcode scanning, which has the following beneficial effects: 1. This oven and baking method based on PDA scanning uses a pull rod to drive a transmission rod, so that when the oven door is pulled, the oven rack can be pulled out simultaneously. The angled design of the oven rack allows it to retract more effectively when the oven door is closed. The bottom guide strip and bottom rollers provide auxiliary guidance and reduce sliding resistance, thus allowing the baking tray to be pulled out simultaneously when the oven door is opened, eliminating the need for users to reach into the oven to retrieve the baking tray.

[0015] 2. This PDA-based oven and baking method, by setting a rack and pinion plate and a transmission gear, allows the transmission gear to move on one side of the rack after the oven rack moves, driving the overall rotation of the lead screw. This, in turn, allows the sliding frame to control the raising or lowering of the pressing body after it moves. This serves to raise the pressing body when the oven door is opened and also to limit the baking tray when the oven door is closed. This solves the problem of the baking tray being inconvenient to fix after being placed and the problem of the baking tray not being able to spring back up after being limited.

[0016] 3. This oven and baking method based on PDA scanning retrieves baking parameters by scanning the code, automatically sets the baking parameters by communicating with the machine via Modbus TCP protocol, controls the machine to start up and operate via Modbus TCP protocol, and automatically records the operation history. This solves the problems of easy errors in manually setting baking parameters leading to product scrapping, low efficiency and poor traceability of traditional recording methods, and quality accidents caused by batches of different baking conditions being mixed.

[0019] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Example

[0020] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 An oven and baking method based on PDA scanning are disclosed. The oven body 1 has a supporting leg 2 fixedly connected to its bottom. An oven door 3 is rotatably connected to one side of the oven body 1. A pull rod 10 is fixedly connected to one side of the oven door 3. A base plate 30 is fixedly connected inside the oven body 1. A bottom groove 21 is formed at the top of the base plate 30. An oven rack 8 is slidably connected to the top of the base plate 30. A baking tray 9 is slidably connected to the top of the oven rack 8. A bottom guide strip 26 is fixedly connected to the bottom of the oven rack 8. Bottom rollers 22 are rotatably connected to the inner wall of the bottom guide strip 26. Heat-resistant rotating shafts 13 are installed on both sides of the oven rack 8. A first transmission rod 11 and a second transmission rod 12 are rotatably connected to the inner wall of the heat-resistant rotating shaft 13. A slider 15 is fixedly connected to one side of the heat-resistant rotating shaft 13. The slider 15 is rotatably connected to one end of the pull rod 10. A groove 14 is formed on the inner wall of the second transmission rod 12. The slider 15 is slidably connected to the inner wall of the second transmission rod 12.

[0021] Through the above technical solution, after the oven door 3 rotates downwards, the pull rod 10 fixed on one side of the oven door 3 is simultaneously driven to rotate, causing the first transmission rod 11 to rotate in the direction of rotation of the pull rod 10 under the action of the slider 15. Simultaneously, this causes the oven rack 8 to slide on the top of the base plate 30. During this process, the slider 15 slides inside the groove 14 opened on the second transmission rod 12, causing the second transmission rod 12 to rotate under force, thus assisting in the stable sliding of the oven rack 8. Furthermore, during the sliding of the oven rack 8, the bottom guide strip 2... The oven rack 8 slides on the top of the base plate 30, and the bottom roller 22 can roll on the top of the base plate 30, thereby reducing the friction when the oven rack 8 slides. At the same time, when the oven door 3 is closing upwards, the bottom of the oven door 3 will first contact the bottom of the oven rack 8. Meanwhile, the oven rack 8 has a rounded shape on one side, which allows the oven rack 8 to retract into the oven body 1 better when the oven door 3 is closed. This allows the user to take out the baking tray 9 when opening the oven door 3, thus avoiding the need for the user to reach into the oven body 1 to retrieve the baking tray 9. Example

[0022] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 A rack plate 16 is fixedly connected to the top of the base plate 30. First fixing blocks 17 and second fixing blocks 23 are fixedly connected to both sides of the oven rack 8. A limit rod 19 is fixedly connected to the top of the first fixing block 17. A transmission gear 24 is rotatably connected to the top of the second fixing block 23. The transmission gear 24 meshes with one side of the rack plate 16. A lead screw 20 is fixedly connected to the top of the transmission gear 24. A sliding frame 18 is threaded onto the outer wall of the lead screw 20. The sliding frame 18 is slidably connected to the outer wall of the limit rod 19. One side of the sliding frame 18 is fixed... A pressing body 25 is fixedly connected to the oven. A telescopic rod 27 is fixedly connected to the inner top wall of the pressing body 25. An abutment block 28 is fixedly connected to the bottom of the telescopic rod 27. The abutment block 28 is slidably connected to the inner surface wall of the pressing body 25. An abutment roller 29 is rotatably connected to the bottom of the abutment block 28. A spring 31 is fixedly connected to the abutment block 28 through the pressing body 25. A double-layer transparent glass 4 is fixedly connected to one side of the oven door 3. A heat-insulating handle 5 is fixedly connected to one side of the oven door 3. A control center 6 is installed on one side of the oven body 1. An adjustment knob 7 is installed on one side of the oven body 1.

[0023] Through the above technical solution, during the sliding of the oven rack 8, the transmission gear 24 slides on one side of the rack plate 16, and the two mesh, allowing the transmission gear 24 to rotate on the top of the second fixed block 23. This causes the lead screw 20 to rotate as a whole, which in turn causes the sliding frame 18 to slide on the outer wall of the limiting rod 19. At the same time, the pressing body 25 is driven to rise, causing the abutting block 28 to drive the abutting roller 29 to rise. The abutting roller 29 can also assist the movement of the baking tray 9. At this time, the baking tray 9 is no longer limited. Similarly, when the oven rack 8 is resetting, the pressing body 25 can be lowered, causing the abutting block 28 to drive the abutting roller 29 to fall and abut the baking tray 9. The telescopic rod 27 and the spring 31 can prevent the abutting roller 29 from being pressed too much. Example

[0024] Please see Figure 9 A baking method, comprising the following steps: S1: PDA terminal: Equipped with a barcode scanning module and a wireless communication module, used to collect batch barcode information; S2: MES server: Stores a database of product baking parameters and matches batch numbers with preset parameters via SQL queries; S3: Oven controller: Integrated Modbus TCP protocol communication interface, receiving RS485 signal conversion instructions from MES; S4: Data logging module: Uses a MySQL database to store operation logs in real time, including fields such as timestamp, operator ID, batch number, and set parameters.

[0025] Through the above technical solution, the PDA barcode scanning baking function allows the operator to use the PDA's barcode scanning function to scan the batch information barcode, retrieve the parameters set by the engineer and automatically set the machine parameters according to the batch number, set the corresponding batch information to the oven through the Modbus TCP protocol, and generate corresponding operation records in the system based on the baking conditions of the first scan, while preventing batches with different baking conditions from operating together.

[0026] In use, as the oven door 3 rotates downwards, the pull rod 10 fixed to one side of the oven door 3 is simultaneously rotated. This causes the first transmission rod 11 to rotate along the direction of rotation of the pull rod 10 under the action of the slider 15, simultaneously causing the oven rack 8 to slide on the top of the base plate 30. During this process, the slider 15 slides inside the groove 14 opened on the second transmission rod 12, causing the second transmission rod 12 to rotate under force, thus assisting the oven rack 8 to slide stably. Furthermore, during the sliding of the oven rack 8, the bottom guide strip 26 on the base plate 30... The top slides, and the bottom rollers 22 can roll on the top of the base plate 30, thereby reducing the friction when the oven rack 8 slides. Simultaneously, when the oven door 3 closes upwards, the bottom of the oven door 3 will first contact the bottom of the oven rack 8. Furthermore, the rounded shape of one side of the oven rack 8 allows the oven door 3 to better push the oven rack 8 into the oven body 1 when closing, allowing the user to easily remove the baking tray 9 when opening the oven door 3. This avoids the user needing to reach into the oven body 1 to retrieve the baking tray 9. During the sliding process of the oven rack 8... In this process, the transmission gear 24 slides on one side of the rack plate 16, and the two mesh, allowing the transmission gear 24 to rotate on the top of the second fixed block 23. This causes the lead screw 20 to rotate as a whole, which in turn causes the sliding frame 18 to slide on the outer wall of the limiting rod 19. At the same time, the pressing body 25 is driven to rise, causing the abutment block 28 to drive the abutment roller 29 to rise. The abutment roller 29 also assists in the movement of the baking tray 9. At this time, the baking tray 9 is no longer limited. Similarly, during the process of the oven rack 8 resetting, the pressing body 25 can be lowered. After lowering, the abutting block 28 drives the abutting roller 29 to descend and abut the baking tray 9. At the same time, the telescopic rod 27 and spring 31 can prevent the abutting roller 29 from being pressed too much. The PDA barcode scanning baking function allows the operator to use the PDA's barcode scanning function to scan the batch information barcode. Based on the batch number, the operator retrieves the parameters set by the engineer and automatically sets the machine parameters. The corresponding batch information is set to the oven through the Modbus TCP protocol. Based on the baking conditions of the first scan, and to prevent multiple batches with different baking conditions from operating at the same time, the corresponding operation record is generated in the system.
