Description

Technical Field

[0001] This invention belongs to the field of baking pan processing technology, specifically a grinding device for baking pan processing. Background Technology

[0002] In the food processing industry, baking pans are commonly used cooking tools. To ensure the hygiene and appearance of the baking pan surface and to improve cooking results, many food processing companies choose to use polishing equipment to treat the surface of the baking pan. Polishing equipment uses rotating polishing wheels or polishing belts to rub and cut the surface of the baking pan, thereby removing the rough layer and minor imperfections on the surface and improving the smoothness and flatness of the surface.

[0003] For example, application CN222430270U discloses a grinding device for baking tray processing, comprising: a base, insert plates fixed at intervals above the base, a tray on each insert plate, a plurality of guide rods fixed below the trays, each guide rod being movably inserted into an adjacent insert plate, a clamping part for holding the baking tray on the tray, a support plate fixed on one side of the base, a flip-top plate hinged to the support plate, a grinding part for grinding the baking tray on the flip-top plate, a moving mechanism for moving the tray upward above the base, a driving mechanism for driving the clamping part to operate at the bottom of the tray, and a rotating mechanism for rotating the grinding part above the flip-top plate. Compared with the prior art, this device can automatically grind the baking tray, eliminating the need for manual hand-held grinding, improving grinding efficiency, and standardizing the grinding process. Based on the aforementioned existing technologies, most baking tray grinding equipment on the market is semi-automatic. In actual production operations, when manually pushing and unloading the baking tray, hands need to be close to the grinding chamber, posing a safety hazard of being scratched or injured by equipment parts. During large-scale continuous production, the labor intensity of repeated manual feeding is extremely high, making it difficult to achieve efficient continuous feeding and adapt to the needs of large-scale production. This reduces the production efficiency of baking tray grinding and increases the operational risks and labor intensity for operators. Therefore, a baking tray grinding device is proposed to solve the problems mentioned in the background technology. Summary of the Invention

[0010] Preferably, the clamping assembly includes a second sliding flexible gripper, one end of which is rotatably connected to both sides of the moving block via a rotating shaft, and the second sliding flexible gripper slides within a fixed frame.

[0013] Preferably, the unloading mechanism includes an unloading port and an unloading plate. The unloading port is located on the front of the housing, and the unloading plate is hinged to the front of the housing. A guide plate is hinged to the inner bottom wall of the unloading port. An extension plate is fixedly connected to the front of the housing. A third electric cylinder is hinged to the front end of the extension plate. The telescopic end of the third electric cylinder is hinged to the surface of the guide plate. Two baffle rods are fixedly connected to the front end of the unloading plate. Two receiving slots are provided on the bottom surface of the unloading plate. Support slots are hinged to the inner walls of the two receiving slots. Two support rods are provided on the front of the housing, and the bottom ends of the two support slots are respectively inserted into the two support rods.

[0014] Preferably, a cylindrical bellows cover is fixedly connected to the bottom surface of the top seat, the bottom end of the cylindrical bellows cover is fixedly connected to the inner bottom wall of the housing, and the cylindrical bellows cover is fitted onto the screw surface of the screw jack.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the feeding mechanism, facilitates the feeding of the baking tray to be polished into the housing. In specific operation, the baking tray is placed on the feeding plate, and then the second motor drives the second lead screw to rotate, enabling the pusher to move horizontally. One end of the pusher pushes the baking tray, which pushes the baffle plate open during the movement until the baking tray is pushed onto the I-shaped plate. After the baking tray is fed, the second motor reverses to reset the pusher, and at the same time, the baffle automatically swings downward to reset, blocking the unloading plate. Finally, the baking tray is clamped and fixed by two clamping components, and then polished in conjunction with the mechanical polishing arm.

[0016] This invention, through its unloading mechanism, facilitates the unloading of the polished baking tray. After the tray is polished, the third electric cylinder first drives the guide plate to swing inwards towards the housing, tilting the guide plate and releasing the tray from the housing's grip. Then, the swing mechanism tilts the tray, causing it to automatically slide onto the guide plate and finally onto the unloading plate. Two baffles prevent the tray from slipping, allowing personnel to easily remove it without tools, reducing the risk to personnel's hands. No additional clamping equipment is needed to remove the tray. Next, the second electric cylinder resets the side plate, making the I-shaped plate horizontal. Finally, the third electric cylinder resets the guide plate, making it vertical within the unloading port, preventing debris from the housing from being discharged.

[0017] This invention, through the coordinated arrangement of a screw jack, top seat, support seat, I-beam plate, and swing mechanism, facilitates the support of a baking tray. When the baking tray needs to be flipped, the screw jack lowers the support seat and I-beam plate until space is available for flipping. Then, the flipping mechanism rotates the corresponding clamping mechanism, flipping the tray. After flipping, the screw jack raises the screw again, allowing the I-beam plate to support the flipped tray once more. The swing mechanism facilitates automatic unloading of the tray, allowing the finished tray to slide accurately to the unloading mechanism, reducing manual unloading workload and making the unloading process faster.

[0018] This invention, through the setting of the second clamping mechanism, utilizes the operation of the fourth electric cylinder to pull back the L-shaped toothed plate, causing the L-shaped toothed plate to rotate the adjusting gear, further driving the second sliding flexible claw to swing until it is vertical. The extension end of the fourth electric cylinder has a self-locking property after being pulled back, thus preventing the L-shaped toothed plate from moving arbitrarily and ensuring the stability of the second sliding flexible claw. After both second sliding flexible claws are in a vertical state, the distance between the two moving blocks is adjusted by the operation of the first motor, allowing the two second sliding flexible claws to clamp and fix the sides of the baking tray, facilitating the mechanical grinding arm to grind the remaining areas of the baking tray. After grinding, the operation of the fourth electric cylinder pushes the L-shaped toothed plate to move, causing the adjusting gear to swing the second sliding flexible claw downwards until it is horizontal, thus retracting the second sliding flexible claw into the fixed frame. This prevents the second sliding flexible claw from protruding above the fixed frame and from interfering with the normal sliding of the baking tray. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 13 As shown, the present invention provides a grinding device for baking pan processing, including a housing 1. A mechanical grinding arm 2 for grinding the baking pan is arranged on the top of the housing 1. Clamping mechanisms are arranged on both sides of the inner wall of the housing 1. One of the clamping mechanisms is equipped with a flipping mechanism. A blocking mechanism is arranged on the top of the housing 1. A screw jack 24 is installed at the bottom inside the housing 1. The top end of the screw of the screw jack 24 is fixedly connected to a top seat 27. The top end of the top seat 27 is movably connected to a support seat 31. The top of 31 is fixed with an I-shaped plate 28. The middle of the I-shaped plate 28 is provided with a clamping mechanism 2. The surface of the top seat 27 is provided with a swing mechanism for tilting the support seat 31. The front and back of the housing 1 are respectively provided with a feeding mechanism for feeding the baking tray and a unloading mechanism for unloading the baking tray. The bottom two sides of the housing 1 are provided with chip discharge ports 20, and the inner bottom wall of the housing 1 is inclined on both sides. The chip collection frame 21 is provided below the two chip discharge ports 20. The surface of the housing 1 is provided with a control panel 25.

[0023] The above solution employs a mechanical grinding arm 2, a mature existing technology, which will not be detailed here. The mechanical grinding arm 2 automatically grinds the surface and sides of the baking tray inside the housing 1, eliminating the need for manual grinding and reducing the risk of injury. The screw jack 24 allows for the raising and lowering of the screw, further enabling the synchronous raising and lowering of the support base 31 and the I-beam plate 28. With this structure, the baking tray to be ground is first automatically fed onto the I-beam plate 28 via a feeding mechanism. Then, a clamping mechanism clamps and fixes the baking tray on the I-beam plate 28. The mechanical grinding arm 2 then grinds the baking tray inside the housing 1. When the baking tray needs to be flipped for grinding, the screw jack 24 lowers the support base 31 and the I-beam plate 28 until space is available for flipping. Then, a flipping mechanism is used to rotate the corresponding... When the clamping mechanism flips, it flips the baking tray. After the tray is flipped, the screw is raised again by the operation of the screw jack 24, so that the I-shaped plate 28 supports the flipped tray again. When it is necessary to grind one position of the clamping mechanism, the other two sides of the tray are clamped by the second clamping mechanism. The mechanical grinding arm 2 can then grind the original clamping position on the tray to ensure the integrity of the grinding. After the tray is completely ground, the second clamping mechanism is released, the unloading mechanism is opened, and the swing mechanism tilts the support 31, causing the tray on the I-shaped plate 28 to slide down toward the unloading mechanism. Finally, the tray is removed from the unloading mechanism. There is no need for personnel to manually remove the tray from the housing 1. Therefore, the feeding and unloading of the tray do not require much operation by personnel, thus improving the grinding efficiency of the tray.

[0024] It is worth noting that when the baking pan does not need to be sanded on the sides, clamping mechanism one or clamping mechanism two can be used directly. In addition, rectangular or round baking pans can be used on the I-shaped plate 28, and clamping mechanism one and clamping mechanism two can also clamp and fix rectangular or round baking pans without changing different clamps.

[0025] like Figures 1 to 3 and Figure 10 As shown, the first clamping mechanism includes a first electric cylinder 4, which is installed on the side of the housing 1 and extends into the housing 1. The telescopic end of the first electric cylinder 4 is rotatably connected to a first U-shaped frame 11, and both ends of the first U-shaped frame 11 are equipped with first sliding column flexible grippers 22.

[0026] Using the above scheme: after the baking tray is placed on the I-shaped plate 28, the two first electric cylinders 4 are operated synchronously to bring the two first U-shaped frames 11 closer to each other until the sides of the baking tray are clamped and fixed by the two sets of first sliding column flexible claws 22. The first sliding column flexible claws 22 can adapt to the sides of the baking tray to clamp it, so as to ensure the stability of the baking tray during subsequent polishing.

[0027] like Figure 1 , Figure 3 and Figure 10 As shown, the flipping mechanism includes a mounting plate 45, which is fixed to the telescopic end of the first electric cylinder 4. A third motor 43 is mounted on the surface of the mounting plate 45. A drive gear 30 is fixed to the output end of the third motor 43. A driven gear 44 is fixed to the middle of the first U-shaped frame 11, and the driven gear 44 meshes with the drive gear 30.

[0028] The above scheme is adopted as follows: When the baking tray needs to be flipped after being clamped by the two sets of first sliding column flexible grippers 22, the operation of the screw jack 24 is first used to control the support base 31 to descend, so that the I-shaped plate 28 is away from the baking tray, ensuring that there is space for the baking tray to be flipped. Then, the operation of the third motor 43 drives the drive gear 30 to rotate, which in turn drives the driven gear 44 to drive the first U-shaped frame 11 to rotate, thereby driving the baking tray to be flipped. After the baking tray is flipped, the operation of the screw jack 24 is used again to support the I-shaped plate 28 on the bottom surface of the baking tray, providing stable support for the baking tray. In addition, the third... The motor 43 has a self-locking property to ensure the stability of the first U-shaped frame 11. In addition, the extension end of the first electric cylinder 4 can only move horizontally and will not rotate. Therefore, the third motor 43 can remain stable at the extension end of the first electric cylinder 4. In addition, to prevent the driving gear 30, driven gear 44 and the third motor 43 from jamming or blocking in the housing 1, a dust cover (not shown in the figure) can be installed on the outside of the component. Regular maintenance can also be performed by using tools such as an air gun to blow away debris from the surface of the component. The above measures are common knowledge and conventional design methods known to those skilled in the art, so they will not be described in detail here.

[0029] like Figures 1 to 3 and Figure 7 As shown, the enclosure mechanism includes a first electric cylinder 4, the bottom surface of which is fixed to the upper surface of the housing 1. A fifth electric cylinder 8 is installed on both sides of the housing 1. The telescopic ends of the two fifth electric cylinders 8 are fixed to a second U-shaped frame 9. The top ends of the two second U-shaped frames 9 are fixed to the top of the rectangular bellows cover 3.

[0030] The above solution is adopted: when the baking tray is being polished in the middle of the housing 1, before that, the two second U-shaped frames 9 can be moved upward by the synchronous operation of the two fifth electric cylinders 8, which further pulls the top of the rectangular accordion cover 3 upward, so that the rectangular accordion cover 3 is in an extended state, thereby expanding the enclosure range of the top of the housing 1 and avoiding excessive debris and dust splashing. In addition, the synchronous operation of the two fifth electric cylinders 8 can be controlled by the driver. The specific connection method is an existing mature technology and will not be described in detail here.

[0031] like Figure 1 , Figure 3, Figure 4 , Figure 6 , Figure 8 , Figure 12 and Figure 13 As shown, the clamping mechanism 2 includes a fixed frame 29, which is embedded in the middle of the support base 31. A first motor 32 is mounted on the surface of the support base 31. The output end of the first motor 32 is located inside the fixed frame 29 and is fixedly connected to a first bevel gear 47. Two opposing first lead screws 37 are rotatably connected to the inner wall of the fixed frame 29. A second bevel gear 46 is fixedly connected to one adjacent end of each of the two first lead screws 37, and the first bevel gear 47 meshes with the two second bevel gears 46. Moving blocks 34 are threaded onto the surfaces of the two first lead screws 37. Clamping components are movably connected to the two moving blocks 34, and the clamping components can be stored inside the fixed frame 29.

[0032] The above scheme is adopted: the first motor 32 drives the first bevel gear 47 to rotate, and the two second bevel gears 46 also rotate together, so that the two first lead screws 37 rotate synchronously. Then, the two moving blocks 34 move relative to each other, thereby driving the two clamping components to move closer to each other, so that the baking tray can be clamped and fixed on the I-shaped plate 28, which facilitates the mechanical grinding arm 2 to grind the rest of the baking tray. In addition, the upper surface of the fixing frame 29 is flush with the upper surface of the I-shaped plate 28 to ensure the stability of the baking tray when placed. Furthermore, personnel can periodically maintain the components inside the fixing frame 29. Air guns can be used to blow away the debris and dust inside to ensure the normal use of the components inside the fixing frame 29 and prevent them from jamming or blocking. According to the actual working conditions, known dust prevention measures are adopted, such as the selection of wear-resistant and dustproof materials. Specific measures will not be detailed here.

[0033] like Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 12 and Figure 13 As shown, the clamping assembly includes a second sliding flexible gripper 23. One end of the second sliding flexible gripper 23 is rotatably connected to both sides of the moving block 34 via a rotating shaft, and the second sliding flexible gripper 23 slides within the fixed frame 29. An adjusting gear 39 is fixedly connected to the rotating shaft of the second sliding flexible gripper 23. A fourth electric cylinder 35 is installed at the bottom of the moving block 34. An L-shaped toothed plate 38 is fixedly connected to the telescopic end of the fourth electric cylinder 35, and the L-shaped toothed plate 38 meshes with the adjusting gear 39.

[0034] Using the above solution: When it is necessary to clamp the baking tray using the clamping assembly, firstly, the operation of the fourth electric cylinder 35 pulls back the L-shaped toothed plate 38, causing the L-shaped toothed plate 38 to rotate the adjusting gear 39, further driving the second sliding flexible gripper 23 to swing until it is vertical. The extension end of the fourth electric cylinder 35 has a self-locking property after being pulled back, so the L-shaped toothed plate 38 will not move arbitrarily, thus ensuring the stability of the second sliding flexible gripper 23. After both second sliding flexible grippers 23 are in a vertical state, the distance between the two moving blocks 34 is adjusted by the operation of the first motor 32, thus fixing the two second sliding flexible grippers 23 to the side of the baking tray. The mechanical grinding arm 2 grinds the remaining parts of the baking tray. After the grinding is completed, the L-shaped toothed plate 38 is moved by the operation of the fourth electric cylinder 35, which causes the adjusting gear 39 to drive the second sliding flexible gripper 23 to swing downward until the second sliding flexible gripper 23 swings to a horizontal position. The second sliding flexible gripper 23 can then be stored in the fixed frame 29, so that the second sliding flexible gripper 23 does not protrude above the fixed frame 29 and does not affect the normal sliding of the baking tray. The second sliding flexible gripper 23 and the first sliding flexible gripper 22 in this device are both existing mature components, which are composed of a rectangular array of elastic sliding columns. They can clamp workpieces of different shapes and have the feature of automatic reset. Specific details will not be described here.

[0035] like Figures 4 to 6 As shown, the swing mechanism includes a second electric cylinder 33, the bottom end of which is hinged to the bottom of the top seat 27. The bottom of the support seat 31 is fixedly connected to a side plate 36. The telescopic end of the second electric cylinder 33 is hinged to one end of the side plate 36. The second electric cylinder 33 is located on the side of the top seat 27 away from the unloading mechanism. The bottom surface of the support seat 31 is hinged to the top of the top seat 27.

[0036] The above solution utilizes the operation of the second electric cylinder 33 to control the support base 31 to swing and tilt. The swinging I-shaped plate 28 then tilts its bottom end towards the unloading mechanism, allowing the polished baking tray to slide smoothly to the unloading mechanism. Therefore, the cooperation between this mechanism and the unloading mechanism enables the automatic unloading of the baking tray, reducing the workload of personnel unloading the baking tray and making the unloading process of the baking tray faster.

[0037] like Figures 1 to 3 and Figure 11As shown, the feeding mechanism includes a feeding plate 5 and a discharge plate 16. The feeding plate 5 is fixed to the back of the housing 1, and the discharge plate 16 is opened on the back of the housing 1. A baffle plate 10 is hinged to the inner top wall of the discharge plate 16. A second motor 42 is installed on the back of the housing 1. A second lead screw 41 is fixed to the output end of the second motor 42. A pusher frame 7 is threaded onto the surface of the second lead screw 41. A guide groove 6 adapted to the pusher frame 7 is opened in the middle of the feeding plate 5. A guide rod 48 is fixed to the inner wall of the guide groove 6, and the pusher frame 7 is slidably sleeved on the guide rod 48.

[0038] The above scheme is adopted: the upper surface of the feeding plate 5 is flush with the inner bottom wall of the unloading plate 16, so as to facilitate the smooth pushing of the baking tray into the unloading plate 16 and into the housing 1. In addition, the bottom end of the baffle plate 10 contacts the inner bottom wall of the unloading plate 16 to ensure that the debris in the housing 1 will not be discharged from the unloading plate 16. When the baking tray needs to be loaded into the housing 1, the baking tray is first placed on the feeding plate 5. Then, the operation of the second motor 42 drives the second lead screw 41 to rotate, so that the pusher 7 can move horizontally. One end of the pusher 7 pushes the baking tray. During the movement, the baking tray will push the baffle plate 10 open until the baking tray is pushed to the I-shaped plate 28. To ensure accurate transfer of the baking tray, the second sliding flexible gripper 23, which is away from the baffle plate 10, can be swung to a vertical position by the operation of the fourth electric cylinder 35 to block and position the baking tray. The other second sliding flexible gripper 23 is stored in the fixed frame 29 and will not affect the normal movement of the baking tray. After the baking tray is fed, the vertical second sliding flexible gripper 23 is reset by the operation of the fourth electric cylinder 35. The second motor 42 is reversed to drive the pusher 7 to reset. At the same time, the baffle plate 10 will automatically swing downward to reset and block the unloading plate 16. Finally, the baking tray is clamped and fixed by the two clamping components.

[0039] like Figure 1 , Figure 3 and Figure 9 As shown, the unloading mechanism includes an unloading port 15 and an unloading plate 16. The unloading port 15 is located on the front of the housing 1, and the unloading plate 16 is hinged to the front of the housing 1. A guide plate 14 is hinged to the inner bottom wall of the unloading port 15. An extension plate 12 is fixedly connected to the front of the housing 1. A third electric cylinder 13 is hinged to the front end of the extension plate 12. The telescopic end of the third electric cylinder 13 is hinged to the surface of the guide plate 14. Two baffle rods 17 are fixedly connected to the front end of the unloading plate 16. Two receiving grooves 40 are opened on the bottom surface of the unloading plate 16. Support grooves 19 are hinged to the inner walls of the two receiving grooves 40. Two support rods 18 are opened on the front of the housing 1, and the bottom ends of the two support grooves 19 are respectively inserted into the two support rods 18.

[0040] Using the above solution: the diameter of the unloading port 15 is larger than the size of the baking tray, so the polished baking tray can be easily removed for unloading. In addition, the hinged design of the unloading plate 16 allows it to be swung downwards for storage when the equipment is not in use. Simply pull out the two support slots 19 from the two support rods 18 and store them in the corresponding storage slots 40, and then swing the unloading plate 16 downwards. The operation is more flexible. After the baking tray on the I-shaped plate 28 is polished, the operation of the third electric cylinder 13 pushes the guide plate 14 to swing inwards into the housing 1, making the guide plate 14 tilted. Then, the clamping of the baking tray is released, and the operation of the second electric cylinder 33 pushes the side plate 36 to swing, so that the tilted bottom of the I-shaped plate 28 and the fixing frame 29 is in the guide plate. As the side plate 36 continues to swing, the baking tray on the I-shaped plate 28 will automatically slide down onto the guide plate 14 and eventually onto the unloading plate 16. Two baffles 17 are used to block the baking tray, preventing it from slipping. Personnel can then remove it without needing to use tools to remove the baking tray from the housing 1, reducing the risk to personnel's hands. There is also no need to use additional clamping equipment to remove the baking tray. In addition, the surface of the baffles 17 is covered with a sponge sleeve, so it will not damage the side of the baking tray. Then, the second electric cylinder 33 drives the side plate 36 to reset, making the I-shaped plate 28 horizontal. Finally, the third electric cylinder 13 drives the guide plate 14 to reset, making it vertical in the unloading port 15, preventing debris from the housing 1 from being discharged from the unloading port 15.

[0041] like Figures 3 to 6 As shown, a cylindrical bellows cover 26 is fixedly connected to the bottom surface of the top seat 27. The bottom end of the cylindrical bellows cover 26 is fixedly connected to the inner bottom wall of the housing 1, and the cylindrical bellows cover 26 is sleeved on the screw surface of the screw jack 24.

[0042] The above solution utilizes a cylindrical bellows cover 26 to protect the screw of the screw jack 24, preventing debris or dust inside the housing 1 from clogging or jamming the screw components. Furthermore, during the lifting and lowering process, the screw of the screw jack 24 will cause the cylindrical bellows cover 26 to retract, thus not affecting the normal lifting and lowering of the support base 31. In addition, personnel can periodically maintain and clean the surface of the cylindrical bellows cover 26 by using a dust blower to remove any remaining debris.

[0043] The working principle and usage process of this invention are as follows: First, the baking tray to be polished is placed on the feeding plate 5. Then, the operation of the second motor 42 drives the second lead screw 41 to rotate, causing the pusher 7 to push the baking tray. The baking tray will push the baffle plate 10 open until the baking tray is pushed onto the I-shaped plate 28. After the baking tray is fed, the reverse rotation of the second motor 42 drives the pusher 7 to reset. At the same time, the baffle plate 10 will automatically swing downwards to reset, blocking the unloading plate 16. Then, the synchronous operation of the two first electric cylinders 4 causes the two first U-shaped frames 11 to move closer to each other until the sides of the baking tray are clamped and fixed by the two sets of first sliding column flexible grippers 22. Then, the mechanical polishing arm 2 polishes the baking tray inside the housing 1. When the baking tray needs to be flipped for polishing... First, the screw jack 24 lowers the support base 31 and the I-beam plate 28, freeing the I-beam plate 28 from supporting the baking tray and creating space for the tray to flip. Then, the screw jack 24 lowers the support base 31, moving the I-beam plate 28 away from the baking tray to ensure sufficient space for flipping. Next, the third motor 43 rotates the drive gear 30, which in turn rotates the driven gear 44, causing the first U-shaped frame 11 to rotate, thus flipping the baking tray. After flipping, the screw jack 24 is used again to support the I-beam plate 28 on the bottom of the baking tray, providing stable support. Finally, the mechanical grinding arm 2 grinds the flipped baking tray. When grinding the clamping points of the two sets of first sliding flexible grippers 22 on the baking tray, the L-shaped toothed plate 38 is first pulled back by the operation of the fourth electric cylinder 35, causing the L-shaped toothed plate 38 to rotate the adjusting gear 39, which in turn drives the second sliding flexible gripper 23 to swing until it is vertical. After both second sliding flexible grippers 23 are in a vertical state, the distance between the two moving blocks 34 is adjusted by the operation of the first motor 32, so that the two second sliding flexible grippers 23 can clamp and fix the sides of the baking tray, making it convenient for the mechanical grinding arm 2 to grind the rest of the baking tray. After the baking tray is ground, the L-shaped toothed plate 38 is moved by the operation of the fourth electric cylinder 35, causing the adjusting gear 39 to rotate. The second sliding flexible gripper 23 swings downwards until it reaches a horizontal position, thus retracting it into the fixing frame 29. This prevents the second sliding flexible gripper 23 from protruding above the fixing frame 29 and thus ensuring the normal sliding of the baking tray. When the baking tray is unloaded from the housing 1, the third electric cylinder 13 first drives the guide plate 14 to swing inwards, tilting it. Then, the second electric cylinder 33 pushes the side plate 36 to swing, positioning the inclined bottom of the I-shaped plate 28 and the fixing frame 29 on the guide plate 14. As the side plate 36 continues to swing, the baking tray on the I-shaped plate 28 will automatically slide onto the guide plate 14 and finally onto the unloading plate 16.Two baffles 17 are used to prevent the baking tray from slipping, allowing personnel to easily remove it without needing tools to remove it from the housing 1, reducing the risk to personnel's hands and eliminating the need for additional clamping equipment. Next, the second electric cylinder 33 resets the side plate 36, making the I-shaped plate 28 horizontal. Finally, the third electric cylinder 13 resets the guide plate 14, making it vertical within the discharge port 15, preventing debris from the housing 1 from being discharged through the discharge port 15. Therefore, this operation achieves automatic feeding and unloading of the baking tray, requiring minimal manual operation and improving the efficiency of baking tray grinding.
