[0030] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them.

"Below," "below," and "under" the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] Example 1:

[0034] like Figure 1-7 As shown, a punching device for the outer shell of a rice cooker includes a frame 1 and multiple clamping components 5 that are driven and engaged inside the frame 1 by a conveying component 2.

[0035] The clamping assembly 5 includes a fixed rod 12, a worm gear 13, and a support plate 14. The worm gear 13 is rotatably connected to the outer wall of the fixed rod 12, and the support plate 14 is fixedly connected to the top of the fixed rod 12. The inner walls of the worm gear 13 and the support plate 14 are respectively provided with a plurality of radially arranged guide grooves 17 and drive grooves 18. The inner walls of the guide grooves 17 and drive grooves 18 are movably fitted with the same guide rod 16, and the top of the guide rod 16 is fixedly connected to an arc-shaped clamping plate 15.

[0036] The rotating worm gear 13, under the limiting cooperation of the guide groove 17 and the drive groove 18, causes the guide rod 16 to drive the arc-shaped clamping plate 15 to move linearly along the guide groove 17. When all the arc-shaped clamping plates 15 move towards the center, the overall outer diameter of the arc-shaped clamping plates 15 can be reduced, which makes it easier to prevent the rice cooker shell from being placed. After placement, the rotating worm gear 13 causes all the arc-shaped clamping plates 15 to move outward until the outer side wall of the arc-shaped clamping plate 15 contacts the inner wall of the rice cooker shell and maintains a certain pressure, thereby achieving the clamping and fixing of the rice cooker shell.

[0037] This device, by setting multiple radially arranged arc-shaped clamping plates 15 and guide rods 16, with the cooperation of guide grooves 17 and drive grooves 18, only needs to rotate the worm gear 13 to drive all the synchronous arc-shaped clamping plates 15 to move outward, and use the arc-shaped clamping plates 15 to clamp the inner wall of the rice cooker shell, thereby simplifying the operation steps. At the same time, the reverse worm gear 13 can drive all the arc-shaped clamping plates 15 to move synchronously towards the center, increasing the convenience of picking up and putting down, thereby improving the punching efficiency of the device.

[0038] In this embodiment, the conveying assembly 2 includes two symmetrically arranged baffles 10. Two conveying rollers 8 are rotatably connected to the opposite side of the two baffles 10 via shaft 7. A horizontal plate 11 is also fixedly connected to the opposite side of the two baffles 10. The horizontal plate 11 and the outer wall of the two conveying rollers 8 are connected to the same conveyor belt 9. A fixing rod 12 is fixedly connected to the outer wall of the conveyor belt 9.

[0039] One of the baffles 10 has a motor 6 fixed to its outer wall by bolts, and the output shaft of the motor 6 is fixedly connected to one of the shafts 7 by a coupling.

[0040] The starter motor 6 drives one of the shafts 7 to rotate the conveyor roller 8. With the cooperation of the other shaft 7 and the conveyor roller 8, the conveyor belt 9 rotates, and the conveyor belt 9 moves all the clamping components 5.

[0041] In this embodiment, each of the two baffles 10 is fixedly connected to a vertical plate 3, and a punching head 4 is installed on the opposite side of each of the two vertical plates 3. A photoelectric gate 31 is also fixedly installed on the top of each of the two baffles 10. The photoelectric gate 31, the punching head 4 and the motor 6 are electrically connected to the same central processing unit.

[0042] The central processing unit is not shown in the diagram. It can be set according to actual production needs and site conditions. The rotating conveyor belt 9 drives the clamping assembly 5 and the rice cooker shell to move towards the punching head 4. When the rice cooker shell passes the photoelectric gate 31, the photoelectric gate 31 transmits a signal to the central processing unit. The central processing unit shuts down the motor 6 and starts the punching head 4 to complete the punching work of the rice cooker shell.

[0043] Example 2:

[0044] A punching device for the outer shell of a rice cooker is provided. This embodiment is based on Embodiment 1 and makes the following improvements, such as... Figure 1-7 As shown:

[0045] The outer wall of the worm gear 13 is engaged with a worm 20. One end of the worm 20 is rotatably connected to a fixing plate 21, which is fixedly connected to the bottom of the bearing plate 14. The other end of the worm 20 is movably fitted with a sleeve 19.

[0046] The sleeve 19 is slidably limited to the bottom of the bearing plate 14, and the inner wall of the sleeve 19 is provided with a threaded groove 22. The inner wall of the worm 20 is fixedly connected with a ball head limiting rod 23 that cooperates with the threaded groove 22.

[0047] The horizontally moving sleeve 19, in cooperation with the threaded groove 22 and the ball head limiting rod 23, causes the worm gear 20 to rotate, thereby driving the worm wheel 13 to rotate.

[0048] Springs 24 are fastened to the opposite sides of the sleeve 19 and the worm gear 20, and a connecting lug 25 is fixedly connected to the outer wall of one end of the sleeve 19. A guide rod 16 is rotatably connected to the inner wall of the connecting lug 25, and a guide wheel 27 is fixedly connected to the outer wall of the shaft 26.

[0049] One of the baffles 10 has a limiting groove 28 on its inner wall. The guide wheel 27 rolls and engages with the inner wall of the limiting groove 28. The limiting groove 28 is composed of the mutually connected limiting groove 28, limiting groove 30, and two transition grooves 29. The transition grooves 29 are inclined surfaces. The depth of the limiting groove 28 is greater than the depth of the limiting groove 30.

[0050] The conveyor belt 9 drives the clamping assembly 5 to move as a whole, and the guide wheel 27 rolls along the limiting groove 28. When the guide wheel 27 rolls in the limiting groove 28, since the depth of the limiting groove 28 is greater than the depth of the limiting groove 30, the spring 24 uses its own elasticity to drive the sleeve 19 away from the worm 20. With the cooperation of the threaded groove 22 and the ball head limiting rod 23, the worm 20 rotates, thereby driving the worm wheel 13 to rotate. With the cooperation of the drive groove 18 and the guide groove 17, all the arc-shaped clamping plates 15 and guide rods 16 rotate. Synchronous centripetal movement; when the guide wheel 27 moves from the limiting groove 28 area to the limiting groove 30 area along with the clamping assembly 5, since the depth of the limiting groove 28 is greater than the depth of the limiting groove 30, the limiting groove 30 pushes the guide wheel 27 outward, causing the sleeve 19 to move towards the worm 20. With the cooperation of the threaded groove 22 and the ball head limiting rod 23, the worm 20 and the worm wheel 13 rotate in opposite directions, causing all the arc-shaped clamping plates 15 and the guide rods 16 to move outward synchronously, using the arc-shaped clamping plates 15 to clamp and fix the outer shell of the rice cooker.

[0051] This device, through the limiting cooperation of guide wheel 27 and limiting groove 1 28, transition groove 29 and limiting groove 2 30, can realize the form switching of arc clamping plate 15 during the conveying of rice cooker shell, thereby reducing the arrangement of power source and simplifying the control logic of the device.

[0052] Working Principle: When in use, the starting motor 6 drives one shaft 7 to rotate the conveyor roller 8. With the cooperation of the other shaft 7 and the conveyor roller 8, the conveyor belt 9 rotates. The conveyor belt 9 moves all the clamping components 5. When a set of clamping components 5 moves to the loading point, the guide wheel 27 connected to that clamping component 5 is located in the limiting groove 28. Since the depth of the limiting groove 28 is greater than the depth of the limiting groove 30, the spring 24 uses its elasticity to move the sleeve 19 away from the worm 20. With the cooperation of the threaded groove 22 and the ball-head limiting rod 23, the worm 20 rotates, thereby driving the worm wheel 13 to rotate. With the cooperation of the drive groove 18 and the guide groove 17, all the arc-shaped clamping plates 15 and guide rods 16 move synchronously towards the center. The operator can easily invert the rice cooker shell onto the support plate 14. Then, the conveyor belt 9 transports the rice cooker shell towards the stamping head 4. The guide wheel 27 gradually moves into the limiting groove 20. Since the depth of the limiting groove 1 28 is greater than the depth of the limiting groove 2 30, the limiting groove 2 30 pushes the guide wheel 27 outward, causing the sleeve 19 to move towards the worm 20. With the cooperation of the threaded groove 22 and the ball head limiting rod 23, the worm 20 and the worm wheel 13 rotate in opposite directions, causing all the arc-shaped clamping plates 15 and the guide rod 16 to move outward synchronously. With the cooperation of the guide wheel 27 and the limiting groove 2 30, it is ensured that the arc-shaped clamping plates 15 always maintain clamping on the rice cooker shell during the punching process. When the rice cooker shell passes through the photoelectric gate 31, the photoelectric gate 31 transmits a signal to the central processing unit. The central processing unit shuts down the motor 6 and starts the punching head 4 to complete the punching work of the rice cooker shell. After the punching is completed, the guide wheel 27 moves back into the limiting groove 1 28, causing all the arc-shaped clamping plates 15 to move inward synchronously, while removing the rice cooker shell.

[0053] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
