[0045] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0046] The inventors, through analysis of existing technologies, discovered that the industry relies heavily on manual folding and packaging, which is inefficient. Current parcel machines also have significant drawbacks: they can only handle the same type of product, requiring manual adjustments to prevent changes in product type. This makes them unsuitable for production lines with mixed product types, thus limiting production methods and reducing efficiency. Therefore, a new demand arose for a machine capable of processing multiple product types simultaneously without human intervention.

[0047] Reference Figure 1-12The diagram shows a schematic of the structure of the wrapping machine of the present invention, which may specifically include the following structure: a clamping assembly 2, a paper feeding assembly, a paper lifting assembly 8, a corner folding assembly 9, and a sensor assembly 3 for measuring the size of the material; the sensor assembly 3 is electrically connected to the corner folding assembly 9; the sensor assembly 3 is disposed on one side of the feeding conveying assembly 1, the paper lifting assembly 8 is disposed between the clamping assembly 2 and the paper feeding assembly, and the corner folding assembly 9 is disposed on both sides of the paper lifting assembly 8; when the wrapping machine is running, the paper feeding assembly places the sheet material onto the paper lifting assembly 8, the clamping assembly 2 places the material on the sheet material, the sensor assembly 3 and the clamping assembly 2 measure the size of the material and transmit the measurement to the corner folding assembly 9, the paper lifting assembly 8 descends to the position of the corner folding assembly 9, and the corner folding assembly 9 wraps the material with the sheet material according to the size of the material.

[0048] In the embodiments of this application, compared to the prior art where "manual wrapping is inefficient, semi-automatic wrapping machines are only suitable for wrapping of the same size, and require machine replacement when changing different products, making them unsuitable for use on a production line with multiple different types of products mixed together," this application provides a method for measuring material size using sensors, enabling the corner-folding component 9 to be designed to adapt to materials of different sizes. Specifically, it includes a clamping component 2, a paper feeding component, a paper-supporting lifting component 8, a corner-folding component 9, and a sensor component 3 for measuring the material size; the sensor component 3 is electrically connected to the corner-folding component 9; the sensor component 3 is disposed on the feeding... On one side of the conveying component 1, a paper-supporting lifting component 8 is provided between the gripping component 2 and the paper-laying component. Folding components 9 are respectively located on both sides of the paper-supporting lifting component 8. When the wrapping machine is running, the paper-laying component places sheet material onto the paper-supporting lifting component 8, the gripping component 2 places the material on the sheet material, the sensor component 3 and the gripping component 2 measure the size of the material and transmit the data to the folding component 9, the paper-supporting lifting component 8 descends to the position of the folding component 9, and the folding component 9 wraps the sheet material according to the size of the material. This application can measure the size of the material using a sensor and a servo motor-driven clamp. Based on the measured size, the subsequent folding component 9 is automatically adjusted and executed, thus achieving wrapping and folding of different products. The gripping and placement method precisely controls the placement position according to the product's dimensions. The rear and front folding components can automatically adjust according to the product's size. Manual adjustment is no longer required during production, thus achieving compatibility with multiple different product sizes and improving production efficiency.

[0049] The following will further describe a parcel machine in this exemplary embodiment.

[0051] In this embodiment, the clamping component 2 is provided with a feeding conveying component 1 on the side away from the paper lifting component 8. The feeding conveying component 1 is equipped with the sensor component 3. The clamping component 2 is provided above the output end of the feeding conveying component 1. When the parcel machine is running, the feeding conveying component 1 conveys the material to the lower end of the clamping component 2, the clamping component 2 clamps the material, and the feeding conveying component 1 moves backward to one side of the paper lifting component 8.

The lifting cylinder 14 is connected to the lifting plate 12. The lifting plate 12 is disposed between the feeding conveyor synchronous belts 11. When the packaging machine is running, the material is moved to below the clamping assembly 2 by the feeding conveyor synchronous belt 11 under the drive of the feeding conveyor servo motor 13. The lifting cylinder 14 drives the lifting plate 12 to lift the material, and the clamping assembly 2 clamps the material.

[0053] As an example, at least two lifting plates 12 are provided, and the two lifting plates 12 are equally spaced on the feeding conveyor synchronous belt 11, thereby enabling the material to be lifted. The lifting plates 12 can be arranged between the feeding conveyor synchronous belts 11, and are arranged in the same direction as the feeding conveyor synchronous belts 11. The feeding conveyor servo motor 13 provides a power source to drive the feeding conveyor synchronous belt 11 and the lifting plates 12 to move.

[0054] In this embodiment, the sensor assembly 3 is electrically connected to the angle bending assembly 9. The sensor assembly 3 is disposed on one side of the feeding conveying assembly 1.

[0055] In one specific embodiment, the sensor measures the length and height of the material. The sensor assembly 3 includes a photoelectric sensor and an ultrasonic sensor. During feeding, the photoelectric sensor, in conjunction with a servo motor, calculates the length of the material by counting the pulses of the servo motor. An ultrasonic sensor is located at the top of the feeding conveying assembly 1 to measure the height of the material. The clamping assembly 2 measures the width of the material; during clamping, the width is measured by counting the pulses of the clamping servo motor 22. The dimensions of the material are obtained by combining these two measurements. The material is then transferred to the corner-folding assembly 9, which adjusts the wrapping of the front and rear corner-folding assemblies according to the material's dimensions, thereby tightly wrapping the sheet material.

The top of the left and right gripping assemblies is equipped with a gripping slide rail 21 and a gripping screw. The gripping servo motor 22 is located at the top of the gripping slide rail 21. The left and right gripping assemblies can move left and right along the gripping slide rail 21. The gripping assembly 2 also includes a gripping lateral movement servo motor 25 and a gripping lifting servo motor 26 located at the top, which control the lateral movement and lifting of the gripping assembly 2, respectively.

[0059] In one specific embodiment, the clamping side plate and the bottom plate 24 are respectively connected to the side and bottom of the material, thereby clamping the material. The bottom plate 24 is moved by a bottom-supporting cylinder, sliding from the side of the material to the bottom.
