Detailed Implementation

[0029] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0030] In the description of this invention, it should be understood that the terms "upper," "lower," "left," "right," "front," "rear," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. It should be understood that the terms "first," "second," etc., are used in this invention to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this invention, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0031] like Figures 1 to 2 As shown, a preferred embodiment of the present invention provides an automatic paper folding machine for a paper wrapping machine, which includes a frame 1, a paper folding mechanism 2, a first pressing mechanism 3, a second pressing mechanism 4, and a rotating output mechanism 5. The paper folding mechanism 2, the first pressing mechanism 3, the second pressing mechanism 4, and the rotating output mechanism 5 are all disposed on the frame 1. The first pressing mechanism 3 is located above the paper folding mechanism 2, and the rotating output mechanism 5 is located below the paper folding mechanism 2.

[0032] like Figures 3 to 5 As shown, the folding mechanism 2 includes a folding table 21 and a paper clamp 22. The paper clamp 22 is installed below the folding table 21. The paper clamp 22 includes a top plate 221, blades 222, a turntable 223, and a first motor 224. The top plate 221 and the turntable 223 are coaxially arranged. Multiple blades 222 are provided and located between the top plate 221 and the turntable 223. The power output end of the first motor 224 is connected to the turntable 223 and is used to drive the blades. The blade 222 rotates; when the turntable 223 rotates to the first angle, the blade 222 is in a retracted state, and the blade 222 is hidden between the top plate 221 and the turntable 223, forming a through hole 225 between the top plate 221 and the turntable 223 for the cookware to pass through; when the turntable 223 rotates to the second angle, the blade 222 is in an extended state, and the blade 222 extends out of the through hole 225 and forms a gathering opening 226 at its center for sealing the packaging paper;

[0033] The folding table 21 has a notch 227 opposite to the through hole 225. The first pressing mechanism 3 is disposed on the folding table 21 and is used to press the cookware through the notch 227 and the through hole 225 to move onto the rotating output mechanism 5. The rotating output mechanism 5 can drive the cookware to rotate so that the upper end of the packaging paper is spirally closed. The second pressing mechanism 4 is used to press the closed packaging paper into the cookware. In this embodiment, the gathering opening 226 is set as a hexagonal opening, and the notch 227 is provided with stiff brushes around its perimeter.

[0034] Before the packaging process, the first pressing mechanism 3 is raised to its highest position and the packaging paper is placed on the folding table 21. The turntable 223 is driven to rotate to the first angle by the first motor 224. The cookware is then placed on the frame 1 at the position corresponding to the paper clamp 22 by manual labor or a robotic arm. The first pressing mechanism 3 is driven to press the cookware through the notch 227 and the through hole 225 to the rotating output mechanism 5. At this time, the turntable 223 is driven to rotate to the second angle by the first motor 224. The blade 222 extends out of the through hole 225 and forms a gathering opening 226 at its center for closing the packaging paper. Then, the rotating output mechanism 5 drives the cookware to rotate, so that the upper end of the packaging paper is spirally closed. Finally, the second pressing mechanism 4 presses the closed packaging paper into the inside of the cookware, thus completing the folding action of the cookware. Using this invention, the packaging of cookware can be automated without manual packaging, which effectively improves production efficiency.

[0035] For example, the upper surface of the blade 222 is provided with a first engaging member 228, the top plate 221 is provided with a plurality of first guide grooves 229 that cooperate with the first engaging member 228, the lower surface of the blade 222 is provided with a second engaging member 230, and the turntable 223 is provided with a plurality of second guide grooves 231 that cooperate with the second engaging member 230. The number of blades 222, first guide grooves 229 and second guide grooves 231 are matched. It should also be noted that, in this embodiment, the first guide grooves 229 are set as straight grooves, and the plurality of first guide grooves 229 are all inclined in the same direction. The second guide grooves 231 are set as arc grooves, and the plurality of second guide grooves 231 are arranged in a vortex shape.

[0036] For example, the first pressing mechanism 3 includes a first mounting frame 31, a second mounting frame 32, a first cylinder 33, and a second cylinder 34. The first mounting frame 31 is fixedly disposed on the upper end of the frame 1. A first linear guide rail pair 35 is provided on the first mounting frame 31. The guide rail of the first linear guide rail pair 35 is fixed on the first mounting frame 31 and arranged in the vertical direction. The second mounting frame 32 is fixedly connected to the slider of the first linear guide rail pair 35. The first cylinder 33 is disposed on the first mounting frame 31. The telescopic end of the first cylinder 33 is connected to the slider of the first linear guide rail pair 35 and is used to drive the second mounting frame 32 to move up and down. The second cylinder 34 is mounted on the second mounting frame 32. The telescopic end of the second cylinder 34 faces downward and is opposite to the center of the through hole 225. A suction cup is provided on the telescopic end of the second cylinder 34. The suction cup is externally connected to a vacuum pump. Before packaging, ensure that the first cylinder 33 positions the second mounting bracket 32 ​​at the top. During packaging, the first cylinder 33 drives the second mounting bracket 32 ​​to move downward, causing the second cylinder 34 mounted on the second mounting bracket 32 ​​to move downward. The second cylinder 34 extends and drives the cookware to pass through the notch 227 and through hole 225 to the rotating output mechanism 5. At the same time, the suction cup can firmly hold the cookware to prevent it from shifting, ensuring that the packaging of the cookware is carried out smoothly.

[0037] For example, such as Figure 7As shown, the rotary output mechanism 5 includes a conveying assembly 51 and a rotating assembly 52. ​​The conveying assembly 51 is disposed below the paper clamp 22, and the rotating assembly 52 is disposed on the input end of the conveying assembly 51. The rotating assembly 52 includes a fixed frame 521, an adjusting frame 522, a drive wheel 523, a rotating shaft 524, a guide wheel 525, and a second motor 526. The fixed frame 521 is fixedly disposed on the frame 1, and the adjusting frame 522 is adjustablely disposed on the frame 1. The fixed frame 521 and the adjusting frame 522 are arranged at intervals, and both the fixed frame 521 and the adjusting frame 522 are located on the input end of the paper clamp 22. Below the paper clamp 22, the drive wheel 523 is fixedly mounted on the rotating shaft 524, which is rotatably mounted on the fixed frame 521. A drive wheel is fixedly mounted on the power output end of the second motor 526, and a driven wheel is fixedly mounted on the rotating shaft 524. The drive wheel is connected to the driven wheel via a belt. The power output end of the second motor 526 drives the drive wheel 523 to rotate by driving the rotating shaft 524. The fixed frame 521 and the adjusting frame 522 are both equipped with guide wheels 525. Both the drive wheel 523 and the guide wheel 525 can abut against the outer peripheral side wall of the cookware. Before packaging, the distance between the fixing frame 521 and the adjusting frame 522 is adjusted according to the actual size of the cookware. The second motor 526 drives the driving wheel to rotate and drives the driven wheel, so that the rotating shaft 524 and the driving wheel 523 rotate synchronously. Therefore, the cookware can rotate under the action of the driving wheel 523. With the cooperation of the paper clamp 22, the end of the packaging paper can complete the spiral closing shape, thus wrapping the cookware.

[0038] Furthermore, the conveying assembly 51 consists of a belt conveyor and a roller conveyor.

[0039] It is understood that the frame 1 is equipped with a second linear guide rail pair 527 and a third cylinder. The guide rail of the second linear guide rail pair 527 is fixedly mounted on the frame 1, and the slider of the second linear guide rail pair 527 is fixedly connected to the adjusting frame 522. The telescopic end of the third cylinder is fixedly connected to the adjusting frame 522 and is used to drive the adjusting frame 522 to move. Thus, when the cookware needs to be delivered, the third cylinder can drive the adjusting frame 522 to move away from the fixed frame 521, thereby facilitating the output of the cookware. After the cookware is delivered by the conveying assembly 51, the third cylinder can drive the adjusting frame 522 to move towards the fixed frame 521, thereby ensuring the rotation and closing operation of the next cookware, making it convenient to use.

[0040] For example, the second pressing mechanism 4 includes a third mounting bracket 41 and a fourth cylinder 42. The third mounting bracket 41 is fixed to the output end of the conveying assembly 51, and the fourth cylinder 42 is mounted on the third mounting bracket 41 with its power output end facing downwards. Thus, the cookware can be conveyed to the second pressing mechanism 4 via the conveying assembly 51, and the upper end of the wrapping paper can be pressed into the cookware by the fourth cylinder 42, completing the entire folding and wrapping process of the cookware.

[0041] For example, the frame 1 is provided with a placement rack 6 for placing cookware and a third motor 61. Two placement racks 6 are provided and arranged opposite each other. The frame 1 is provided with a third linear guide rail pair 62, whose guide rails are fixed to the frame 1 and arranged in a left-right direction. The placement rack 6 is fixedly connected to the slider of the third linear guide rail pair 62. The power output end of the third motor 61 is fixedly connected to the slider of the third linear guide rail pair 62 and is used to drive the placement rack 6 to move left and right. Before packaging, the cookware is placed on the placement rack 6 manually or by a robotic arm. After the suction cup on the second cylinder 34 adsorbs the cookware, the third motor 61 drives the two placement racks 6 to move away from each other. This prevents the cookware from touching the packaging paper before it is adsorbed by the suction cup, preventing the packaging paper from shifting before packaging, effectively reducing manual adjustment time and speeding up the folding efficiency of the cookware.

[0042] Specifically, the placement rack 6 is equipped with guide rollers 63, limiting wheels 64, and limiting frames 65. Multiple guide rollers 63 are evenly spaced in the front-to-back direction. The limiting frames 65 are mounted on the placement rack 6 and are inclined. The limiting wheels 64 are mounted on the limiting frames 65. Thus, the limiting wheels 64 prevent the cookware from slipping out, facilitating use.

[0043] In this embodiment, the first motor 224 is provided with a gear 234, and the turntable 223 is provided with a toothed mouth 235 that cooperates with the gear 234.

[0044] For example, both the top plate 221 and the turntable 223 are annular. The top plate 221 has multiple mounting brackets 232. The upper end of each mounting bracket 232 is fixedly connected to the frame 1, and the lower end is fixedly connected to the top plate 221. Guide wheels 233 are mounted on each mounting bracket 232, and each guide wheel 233 has a U-shaped groove that matches the thickness of the turntable 223. The guide wheels 233 prevent the turntable 223 from deflecting during rotation, thus avoiding damage to the paper clamp 22.

[0045] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
