Description

Technical Field

[0001] This invention relates to the field of sheet metal coating machine technology, specifically to a vertical sheet metal coating machine and a sheet metal coating method. Background Technology

[0002] The coating machine places the workpiece in a vacuum environment and coats it by evaporating the coating material and using physical vapor deposition to adhere it to the surface of the workpiece.

[0003] Patent publication number CN116219387B relates to a rotary vacuum coating machine, including a base, a vacuum chamber above the base, multiple main supports around the vacuum chamber, the lower ends of the main supports being located on the top surface of the base, an anti-rotation mechanism below the vacuum chamber with its bottom surface located in the middle of the top surface of the base, multiple coating units in the middle of the vacuum chamber, the lower ends of the coating units being located on the upper ends of the anti-rotation mechanism, and multiple sealing units bolted to the top and bottom of the vacuum chamber, each sealing unit including an upper sealing cover and a lower sealing cover. This patent improves efficiency by having multiple coating units rotate around a single coating source, sharing the same coating source, thereby reducing material waste and production costs without increasing the consumption of the coating source.

[0004] In the aforementioned patent, multiple coating units rotate around a single coating source, sharing the same coating source. This improves efficiency without increasing the consumption of the coating source, significantly reducing material waste and thus lowering production costs. However, when setting up the substrate roll, this patent requires consideration of whether the substrate is adhered and curled on the surface of the unwinding roller, and also ensures that the substrate head is flat and adheres to the take-up roller to guarantee that the take-up roller can smoothly take up the substrate. The preliminary work is quite cumbersome. Moreover, in existing coating technologies, once the workpiece is placed in the equipment, its position is generally fixed. If there are many workpieces, they are prone to shaking and obstruction after the rotating device is started, affecting the coating effect. The motor driving the rotating device will continuously generate electricity, resulting in a large amount of energy consumption and increasing coating costs. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide a vertical plate coating machine and a plate coating method, which solves the technical problem in the prior art that when the substrate roll is nested, it is necessary to consider whether the substrate is attached to the surface of the unwinding roller and to ensure that the substrate head is flat and attached to the winding roller in order to ensure that the winding roller can smoothly wind up the substrate, which is a relatively cumbersome pre-processing.

[0006] According to one aspect, at least one embodiment of the present invention provides a vertical sheet metal coating machine, comprising a machine body and a cover, the cover being rotatably mounted on the surface of the machine body, a motor being mounted on the top of the machine body, the output end of the motor extending through the surface of the machine body into the interior of the machine body, a slide rail being fixedly mounted on the inner wall of the machine body, a frame being sleeved on the surface of the slide rail, the cover blocking the frame when closed, keeping the frame inside the machine body, and the cover releasing the frame when opened, allowing the frame to slide out through the slide rail for easy operation by the operator, the output end of the motor engaging with the top of the frame, and the rotation of the motor output end pushing the frame to rotate, a plurality of fixed frames being slidably mounted on the surface of the frame, the fixed frames being used to position and fix the sheet metal, baffles being provided on the top and top sides of the fixed frames, the baffles providing lateral positioning of the sheet metal, clips being slidably mounted between the baffles, and a first spring being provided between the clips and the fixed frames, the first spring... The elastic force provides clamping force for positioning the plate by the clamps. The operator only needs to place the plate between the upper and lower clamps to complete the initial positioning of the plate, without the need for complete fixation, saving operation steps and improving efficiency. The clamp surface is provided with a frustum, the fixing frame surface is slidably mounted with a push plate, the top of the push plate is fixedly mounted with a diagonal rod, and the top of the fixing frame is slidably mounted with a pressure block. By pressing the inclined surface of the diagonal rod with the pressure block, the push plate moves to press the conical surface of the frustum, clamping the clamp and completing the complete fixation of the plate. The slide rail surface is fixedly mounted with a pressure strip, the frame surface is slidably mounted with a circular frame, and the circular frame surface near the pressure block is fixedly mounted with a stop bar. In order to lock all the clamps and fix all the plates at the same time after the frame enters the machine body, the inclined surface at the bottom of the pressure strip presses the circular frame to move the circular frame downward. After the circular frame moves downward, it can drive all the stop bars to press the corresponding pressure blocks, thereby fixing all the clamps.

[0007] For example, in a vertical plate coating machine provided by at least one embodiment of the present invention, a second spring is provided between the frame and the slide rail. The elastic force of the second spring allows the frame to slide out through the slide rail. The clamp surface is provided with an inclined surface. When the plate surface pushes the inclined surface, the clamp can be automatically lifted, which facilitates operation.

[0008] A drive wheel is provided at the bottom of the frame. When the frame rotates, it drives the drive wheel to rotate. A driven wheel is rotatably installed inside the machine body. The surfaces of the drive wheel and the driven wheel mesh. When the drive wheel rotates, it pushes the driven wheel to rotate. A slide rod is slidably installed inside the machine body. A vertical rod is fixedly installed at the edge of the driven wheel. The slide rod is sleeved on the surface of the vertical rod. When the driven wheel rotates, it drives the vertical rod to make a circular motion. When the vertical rod moves, it pushes the slide rod to move back and forth. Each time the slide rod slides outward, it pushes out the fixed frame that has moved in front of the slide rod, so that the corresponding plate leaves the plate array and is exposed to the outside, making full contact with the coating material. Even when the fixed frame is set compactly, each plate can still be fully coated, ensuring the coating effect. A third spring is provided between the fixed frame and the frame. The elastic force of the third spring makes the fixed frame return to its original position.

[0009] According to another aspect, at least one embodiment of the present invention also provides a vertical sheet metal coating machine. A limiting plate is slidably installed on the moving path of the fixed frame. A fourth spring is provided between the limiting plate and the frame. The elastic force of the fourth spring causes the limiting plate to reset. A first rotating plate is rotatably installed at one end of the limiting plate, and an inclined plate is slidably installed at the other end. A first stop is installed between the first rotating plate and the limiting plate. The first stop limits the first rotating plate from one side, so that the first rotating plate can only rotate to one side. When the fixed frame passes through one side of the first rotating plate to the other side, the fixed frame is limited, so that the slid-out fixed frame will not immediately reset, prolonging the exposure time of the sheet metal and ensuring that the corresponding sheet metal can fully contact the coating material. A slot is opened on the surface of the frame near the inclined plate. A stop bar is fixedly installed inside the machine body. The stop bar presses against the inclined plate to move the limiting plate away from the fixed frame, releasing the limitation on the fixed frame. The fixed frame drives the sheet metal to reset. At the same time, the inclined plate moves into the slot and no longer contacts the stop bar, passing the stop bar and causing the limiting plate to reset.

[0010] One end of the slide bar is provided with an arc block, the shape of which matches the surface shape of the fixed frame, so as to facilitate docking with the fixed frame and pushing the fixed frame to move. A fifth spring is provided between the inclined plate and the limiting plate.

[0011] For example, in at least one embodiment of the vertical plate coating machine provided by the present invention, the drive wheel is slidably mounted on the bottom of the frame, a plurality of convex rings are fixedly mounted on the surface of the drive wheel, a push block is fixedly mounted on the inner wall of the slide rod, the surface of the push block is provided with an inclined surface, the slide rod drives the push block to move, and when the inclined surface of the push block contacts the convex rings, it squeezes the convex rings to move upward, causing the drive wheel to move upward. A limit rod is provided at the bottom of the frame near the convex rings, and the limit rod limits the moved convex rings to determine the working height of the drive wheel. A second limit rod is rotatably mounted on the surface of the limit rod. A second stop is provided between the second rotating plate and the limiting rod. The second stop limits the second rotating plate from one side, so that the second rotating plate can only rotate to one side. When the convex ring moves upward and passes the second rotating plate, the convex ring is limited by the second rotating plate. An electrical switch is provided at the bottom of the frame. The electrical switch is electrically connected to the motor. Each time the push block squeezes the convex ring, the drive wheel will rise a little. When the drive wheel is raised to the maximum height, it squeezes the electrical switch, causing the electrical switch to control the motor to temporarily cut off the power. The frame rotates by inertia, saving power.

[0012] A sleeve rod is rotatably mounted at the bottom of the frame. An elastic element is provided between the sleeve rod and the frame. When the frame rotates, the resistance between the elastic element and the sleeve rod drives the sleeve rod to rotate. A limiting rod is slidably mounted on the surface of the sleeve rod. When the sleeve rod rotates, it drives the limiting rod to rotate. A sixth spring is provided between the limiting rod and the sleeve rod. The elastic force of the sixth spring can cause the limiting rod to pop out from the surface of the sleeve rod. One end of the spring is set as an arc surface that penetrates the surface of the sleeve rod. When the sleeve rod pushes the limiting rod to rotate until it fits against the inner wall of the sliding rod, it stops, so that the arc surface side of the limiting rod always fits against the inner wall of the sliding rod. Under the rotational torque of the frame, the reaction force of the inner wall on the limiting rod resists the limiting rod to prevent it from popping out, so that the limiting rod continuously limits the convex ring. A trapezoidal block is fixedly mounted on the top of the limiting rod. The surface of the trapezoidal block is set with an inclined surface and is flush with the electrical switch. After the limiting rod pops out, it drives the trapezoidal block to squeeze the electrical switch, so that the motor is turned on again.

[0013] The thickness of the driven wheel is greater than that of the driving wheel, and the driven wheel is aligned with the bottom of the driving wheel. For a period of time after the driving wheel begins to move, it remains engaged with the driven wheel to provide kinetic energy to the driven wheel. When the driving wheel is raised to its maximum height, it disengages from the driven wheel. The driven wheel then rotates due to inertia, relying on the kinetic energy provided by the driving wheel. Furthermore, the disengagement of the driving wheel and the driven wheel reduces the resistance during their respective rotations.

[0014] A coating method using a vertical sheet metal coating machine, comprising the following steps: Step 1: Open the cover, the frame pops out from inside the machine body, place the plate on the surface of the fixing frame, and use the elastic clamping of the clip to initially position the plate. Close the cover, the cover pushes the frame back into the machine body, and at the same time the clip locks to completely fix the plate, ready for coating. Step 2: The motor drives the frame and driven wheel to rotate. The frame drives all the plates to rotate, so that the plates come into contact with the coating material in the evaporation state inside the machine body to perform coating. The driven wheel drives the slide bar to slide back and forth. Each time the slide bar slides, it will push out one of the plates to fully contact the coating material. Step 3: After the motor has been running for a period of time, the power is cut off. The frame and driven wheel rotate by inertia. When the inertia is insufficient to maintain the rotation of the frame and driven wheel, the motor is powered on again.

[0015] The beneficial effects of this invention are as follows: In this invention, the elastic clamping of the clips eliminates the need for workers to completely fix the boards during installation, saving operational steps and making it easier to use. Once the frame enters the machine body, it automatically and completely fixes all the boards. At the same time, the compact structure between the fixing frames allows for more boards to be coated simultaneously, saving internal space of the machine body. After the coating is completed and the cover is opened, the frame automatically pops out under the elastic force and releases the fixation of all the boards, making it convenient for workers to remove the boards.

[0016] In this invention, the frame rotates continuously during the coating process, bringing the sheet metal into contact with the coating material for coating. Simultaneously, the sliding rod allows one sheet metal to slide out from the others each time, and after sliding out, it pauses for a period before returning to its original position, ensuring more thorough contact with the coating material. This design ensures that the machine can accommodate a large number of sheets at once while guaranteeing that each sheet metal receives sufficient contact with the coating material. In this invention, the motor intermittently starts and stops when driving the frame to rotate. During the motor power-off process, the frame and driven wheel rotate by inertia without relying on the motor power. When the inertial force is about to be insufficient to drive the frame and driven wheel to rotate, the motor starts again to provide power. This ensures that the frame can continue to rotate while shortening the total working time of the motor, reducing energy consumption, saving electricity, and when the motor is powered off, the frame and driven wheel separate, reducing the resistance during rotation, increasing the rotation time, extending the motor power-off time, and improving the energy-saving effect.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0020] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product.

[0024] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figures 1-12The diagram illustrates a vertical sheet metal coating machine and method according to an embodiment of the present invention. The machine includes a body 1 and a cover 2. The cover 2 is rotatably mounted on the surface of the body 1. A motor 3 is mounted on the top of the body 1, with its output end extending through the surface of the body 1 into the interior. A slide rail 6 is fixedly mounted on the inner wall of the body 1, and a frame 4 is fitted onto the surface of the slide rail 6. When the cover 2 is closed, it blocks the frame 4, keeping it inside the body 1. When the cover 2 is opened, it releases the restriction on the frame 4, allowing it to slide out via the slide rail 6 for easy operation. The output end of the motor 3 engages with the top of the frame 4, and rotation of the motor 3 pushes the frame 4 to rotate. Several fixing frames 5 are slidably mounted on the surface of the frame 4, used for positioning and fixing the sheet metal. Baffles 11 are provided on the top and both sides of the fixing frames 5, providing lateral positioning for the sheet metal. Clips are slidably mounted between the baffles 11. 10. A first spring is provided between the clamp 10 and the fixing frame 5. The elastic force of the first spring provides clamping force for the clamp 10 to position the plate. The operator only needs to put the plate between the upper and lower clamps 10 to complete the initial positioning of the plate. A cone 14 is provided on the surface of the clamp 10. A push plate 15 is slidably installed on the surface of the fixing frame 5. A diagonal rod 13 is fixedly installed on the top of the push plate 15. A pressure block 12 is slidably installed on the top of the fixing frame 5. By pressing the inclined surface of the diagonal rod 13 with the pressure block 12, the push plate 15 moves to press the conical surface of the cone 14, thus clamping the clamp 10. A pressure strip 7 is fixedly installed on the surface of the slide rail 6. A circular frame 8 is slidably installed on the surface of the frame 4. A stop rod 9 is fixedly installed on the surface of the circular frame 8 near the pressure block 12. The inclined surface at the bottom of the pressure strip 7 presses the circular frame 8 to make the circular frame 8 move downward. After the circular frame 8 moves downward, it can drive all the stop rods 9 to press the corresponding pressure blocks 12, thereby fixing all the clamps 10.

[0026] In this embodiment, a second spring is provided between the frame 4 and the slide rail 6. The elastic force of the second spring allows the frame 4 to slide out through the slide rail 6. The surface of the clamp 10 is provided with an inclined surface. When the plate surface pushes the inclined surface, the clamp 10 can be automatically lifted, which facilitates operation.

[0027] See in some examples Figures 1-12 In existing coating processes, the installation and removal of workpieces are cumbersome, requiring the operation of multiple workpieces one by one, which affects work efficiency. The vertical coating machine of this invention simplifies the installation and removal of the board when coating the board, and has good stability and high work efficiency.

[0028] Before coating the sheet material, open the cover 2. After the cover 2 is rotated open, it releases the restriction on the frame 4. After the frame 4 is released, it pops outward under the elastic force of the second spring, presenting itself to the operator, making it easier for the operator to install the sheet material. Press the sheet material against the inclined surface of the upper and lower clamps 10 and push the sheet material into the fixing frame 5. The surface of the sheet material presses against the inclined surface of the clamps 10, pushing the clamps 10 to open up and down, allowing the sheet material to enter the fixing frame 5. The clamps 10 descend under the elastic force of the first spring to clamp the sheet material, completing the initial positioning of the sheet material. In this process, the operator is spared the operation of completely fixing the workpiece; only the workpiece needs to be placed in. After all the mounting frames 5 are filled with the plates, close the cover 2. When the cover 2 resets, it pushes the frame 4 back into the body 1. During the movement of the frame 4, the circular frame 8 moves. When the circular frame 8 contacts the pressure strip 7, it slides downward under the pressure of the bottom slope of the pressure strip 7. The sliding circular frame 8 drives the abutment rod 9 to move downward. The abutment rod 9 moves downward and presses the pressure block 12. The pressure block 12 moves downward and then presses the top slope of the inclined rod 13, causing the inclined rod 13 to move. The inclined rod 13 drives the push plate 15 to move towards the mounting frame 5. After the push plate 15 moves, the inner wall presses the conical surface of the cone 14, clamping the clip 10 and completing the complete fixation of the plates. This invention eliminates the need for complete fixation of the plates during the plate installation stage. It is simple to operate. When all the plates are placed, closing the cover 2 will automatically fix all the plates completely. After the coating work is completed, opening the cover 2 will automatically pop out the frame 4 and release the fixation of the plates, making it easy to remove the plates and improving work efficiency.

[0029] refer to Figures 1-12 In some embodiments, a drive wheel 19 is provided at the bottom of the frame 4. When the frame 4 rotates, it drives the drive wheel 19 to rotate. A driven wheel 17 is rotatably installed inside the body 1. The surfaces of the drive wheel 19 and the driven wheel 17 mesh. When the drive wheel 19 rotates, it pushes the driven wheel 17 to rotate. A slide rod 16 is slidably installed inside the body 1. A vertical rod is fixedly installed at the edge of the slide rod 16. The slide rod 16 is sleeved on the surface of the vertical rod. When the driven wheel 17 rotates, it will drive the vertical rod to rotate. Because the vertical rod is located at the edge of the surface of the driven wheel 17, when the vertical rod 17 rotates along the circumferential trajectory, it will push the slide rod 16 to move back and forth. Each time the slide rod 16 slides outward, it will push out the fixed frame 5 that has moved in front of the slide rod 16. A third spring is provided between the fixed frame 5 and the frame 4. The elastic force of the third spring makes the fixed frame 5 return to its original position.

[0030] A limiting plate 22 is slidably installed on the moving path of the fixed frame 5. A fourth spring is provided between the limiting plate 22 and the frame 4. The elastic force of the fourth spring causes the limiting plate 22 to reset. A first rotating plate 23 is rotatably installed on one end of the limiting plate 22, and an inclined plate 25 is slidably installed on the other end. A first stop 24 is installed between the first rotating plate 23 and the limiting plate 22. The first stop 24 limits the first rotating plate 23 from one side, so that the first rotating plate 23 can only rotate to one side. When the fixed frame 5 passes through one side of the first rotating plate 23 to the other side, the fixed frame 5 is limited. A slot 26 is opened on the surface of the frame 4 near the inclined plate 25. A stop bar 20 is fixedly installed inside the machine body 1. The stop bar 20 presses against the inclined plate 25 to make the limiting plate 22 move away from the fixed frame 5, release the limitation on the fixed frame 5, and the fixed frame 5 drives the plate to reset.

[0031] One end of the slide bar 16 is provided with an arc block 21. The shape of the arc block 21 matches the surface shape of the fixed frame 5, which facilitates docking with the fixed frame 5 and pushing the fixed frame 5 to move. A fifth spring is provided between the inclined plate 25 and the limiting plate 22. The elastic force of the fifth spring causes the inclined plate 25 to return to its original position.

[0032] In this embodiment, the drive wheel 19 is slidably mounted on the bottom of the frame 4. Several protruding rings 27 are fixedly mounted on the surface of the drive wheel 19. A push block 18 is fixedly mounted on the inner wall of the slide rod 16. The surface of the push block 18 is provided with an inclined surface. The slide rod 16 drives the push block 18 to move. When the inclined surface of the push block 18 contacts the protruding rings 27, it squeezes the protruding rings 27 upwards, causing the drive wheel 19 to move upwards. A limit rod 29 is provided at the bottom of the frame 4 near the protruding rings 27. The limit rod 29 limits the movement of the protruding rings 27. A second... A second stop 32 is provided between the rotating plate 33 and the limiting rod 29. The second stop 32 limits the second rotating plate 33 from one side, so that the second rotating plate 33 can only rotate to one side. When the convex ring 27 moves upward and passes the second rotating plate 33, the convex ring 27 is limited by the second rotating plate 33. An electrical switch 30 is provided at the bottom of the frame 4. The electrical switch 30 is electrically connected to the motor 3. When the drive wheel 19 is raised to the maximum height, it squeezes the electrical switch 30, so that the electrical switch 30 controls the motor 3 to temporarily cut off the power.

[0033] A sleeve rod 28 is rotatably mounted at the bottom of frame 4. An elastic element is provided between sleeve rod 28 and frame 4. When frame 4 rotates, the resistance between the elastic element and sleeve rod 28 drives sleeve rod 28 to rotate. A limiting rod 29 is slidably mounted on the surface of sleeve rod 28. When sleeve rod 28 rotates, it will drive limiting rod 29 to rotate. A sixth spring is provided between limiting rod 29 and sleeve rod 28. The elastic force of the sixth spring can cause limiting rod 29 to pop out from the surface of sleeve rod 28, and one end is set as an arc surface that penetrates the surface of sleeve rod 28. When sleeve rod 28 pushes limiting rod 29 to rotate until it is in contact with the inner wall of slide rod 16, it stops, so that the arc surface side of limiting rod 29 is always in contact with the inner wall of slide rod 16. A trapezoidal block 31 is fixedly mounted on the top of limiting rod 29. The surface of trapezoidal block 31 is provided with a slope and is flush with electrical switch 30. After limiting rod 29 pops out, it drives trapezoidal block 31 to squeeze electrical switch 30, so that motor 3 is turned on again.

[0034] The thickness of the driven wheel 17 is greater than that of the drive wheel 19, and the driven wheel 17 is aligned with the bottom of the drive wheel 19. For a period of time after the drive wheel 19 begins to move, it remains engaged with the driven wheel 17 to provide kinetic energy to the driven wheel 17. When the drive wheel 19 is raised to its maximum height, it disengages from the driven wheel 17.

[0035] In this embodiment, after the frame 4 enters the body 1, its top engages with the output end of the motor 3, turning on the device. The motor 3 starts working, and the rotation of the output end of the motor 3 drives the frame 4 to rotate, causing the rods mounted on the surface of the frame 4 to be uniformly coated. When the frame 4 rotates, it drives the drive wheel 19 to rotate, which in turn drives the driven wheel 17 to rotate. When the driven wheel 17 rotates, it pushes the slide bar 16 to move back and forth. The slide bar 16 drives the arc block 21 to move, pushing out the fixed frame 5 that has rotated to the front end of the slide bar 16. This intermittently pushes out each plate one by one, away from the plate array, and uniformly adsorbs the free coating material inside the body 1. At the same time, when the fixed frame 5 is pushed out by the slide bar 16, it will pass the first rotating plate 23 and be limited by the limiting plate 22, causing the fixed frame to be... 5. The plate will not immediately reset. As the frame 4 continues to rotate, it will cause the limiting plate 22 to gradually approach the stop bar 20, and the bottom slope of the inclined plate 25 will contact the stop bar 20. This will limit the limiting plate 22, causing it to stop rotating with the frame 4. After the frame 4 continues to rotate a certain distance, it will move the fixing frame 5 away from the first rotating plate 23, releasing the limiting effect on the fixing frame 5. At this time, the fixing frame 5 will be pushed back into the plate array by the force of the third spring. Simultaneously, the frame 4 will move the slot 26 above the inclined plate 25. The bottom slope of the inclined plate 25 will collapse into the slot 26 due to the pressure of the stop bar 20, moving away from the stop bar 20. This will release the limit bar 20 from limiting the limiting plate 22, and the limiting plate 22 will reset under the force of the fourth spring. In this way, the plate pushed out by the slide bar 16 will stay outside for a period of time before resetting, increasing the time for the plate to absorb the coating material and ensuring the coating effect. In this invention, the spacing between the fixed frames 5 is small, which can accommodate more plates for coating at one time. At the same time, each plate can be pushed out by the slide bar 16 when it passes in front of the slide bar 16, so that each plate can be in uniform contact with the coating material evaporated inside the body 1. This saves the internal space of the body 1 while ensuring coating efficiency.

[0036] Each time the slide bar 16 slides, it drives the push block 18 to move towards the drive wheel 19. The inclined surface of the push block 18 presses against the convex ring 27 on the surface of the drive wheel 19, causing the convex ring 27 to drive the drive wheel 19 upward. At the same time, after the convex ring 27 moves upward and passes the second rotating plate 33, it is limited by the limiting rod 29, thereby changing the working height of the drive wheel 19. The limiting rod 29 can always position the real-time working height of the drive wheel 19 by limiting the convex ring 27 at a certain height. When the bottom convex ring 27 is limited by the limiting rod 29, the drive wheel 19 moves to the maximum height. At the same time, the top presses against the electrical switch 30, cutting off the power supply to the motor 3 by pressing the electrical switch 30. This allows the frame 4 and the driven wheel 17 to rotate temporarily under inertia. Even when the motor 3 is off, the plate can still rotate, which can save electricity and reduce energy consumption in the coating process.

[0037] When frame 4 rotates, it drives sleeve rod 28 to rotate, which in turn drives limit rod 29 to rotate. Frame 4 is connected to sleeve rod 28 via an elastic element, and sleeve rod 28 is in a movable state on the surface of frame 4. Since limit rod 29 is inevitably limited by the inner wall of slide rod 16 after rotation, as frame 4 continues to rotate, it continuously drives sleeve rod 28 to press limit rod 29, keeping limit rod 29 always in contact with the inner wall of slide rod 16. When frame 4 rotates under the power of motor 3, the torque of motor 3 will press one side of limit rod 29 through sleeve rod 28, while the other side of limit rod 29 is set as an arc surface. Under the reaction force of the inner wall of slide rod 16, it slides towards convex ring 27 and always has a tendency to move towards convex ring 27, providing support for limit rod 29 to limit convex ring 27. When motor 3 is de-energized, the torque of frame 4 rotating by inertia gradually becomes insufficient to press limit rod 29. The convex ring 27 is limited by the spring 9. The limiting rod 29 then pops out from the convex ring 27 under the elastic force of the sixth spring, releasing the limitation on the convex ring 27. The drive wheel 19 can then fall down under the action of gravity and re-engage with the driven wheel 17. At the same time, when the limiting rod 29 pops out, it drives the trapezoidal block 31 to move and press the electrical switch 30 again, so that the motor 3 is powered on again. In this way, the motor 3 is de-energized after the drive frame 4 rotates a certain distance. The frame 4 and the driven wheel 17 rotate by inertia. At the same time, the drive wheel 19 will also lift up to disengage from the driven wheel 17, reducing the resistance when the frame 4 and the driven wheel 17 rotate, extending the rotation time, and improving the energy saving effect. When the inertial force is insufficient to make the frame 4 rotate, the drive wheel 19 re-engages with the driven wheel 17, and the motor 3 restarts to drive the frame 4 and the driven wheel 17 to rotate. Through the intermittent starting of the motor 3, energy consumption is effectively reduced and electricity is saved.
