DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0033] The embodiment of the present application discloses an automatic feeding device for packaging cutting.

[0034] An automatic feeding device for packaging and cutting includes a loading device, a feeding device, a positioning device, a cutting device, and an output device. The loading device is responsible for placing raw materials into a hopper; the feeding device is responsible for transporting the raw materials from the hopper to the cutting device; the positioning device fixes the raw materials in the correct position after they arrive at the cutting device; the cutting device cuts the raw materials according to specific size requirements; and the output device transports the cut materials to the next production process.

[0035] The feeding device consists of a frame 1, an adjustment frame 2, and a flattening assembly 3. The length of the frame 1 aligns with the length of the packaging material 4, ensuring smooth material conveyance. Multiple adjustment frames 2 are arranged along the length of the frame 1. Each adjustment frame 2 is driven by a first drive unit and moves along the width of the frame 1 to accommodate materials of varying widths. The flattening assembly 3 is compatible with and mounted on the adjustment frames 2. It clamps the packaging material 4 and rolls with it to ensure smooth conveyance.

[0036] According to the conveying position of the packaging raw material 4, the initial position of the flattening assembly 3 is adjusted by the adjustment frame 2, so that the packaging raw material 4 passes through the flattening assembly 3 during the conveying process, and the packaging raw material 4 is clamped by the flattening assembly 3. When the packaging raw material 4 passes through the flattening assembly 3, multiple flattening assemblies 3 gradually flatten the packaging raw material 4, thereby improving the convenience of correcting the deviation of the packaging raw material 4. The side wall of the frame 1 is provided with a plurality of adjustment holes 11 adapted to the adjustment frame 2 along the length direction of the frame 1. The adjustment frame 2 slides with the adjustment holes 11 to improve the movement stability of the adjustment frame 2. In the embodiment of the present application, there are five adjustment holes 11. When the adjustment frame 2 slides, the inner wall of the adjustment hole 11 limits and guides the adjustment frame 2.

[0037] The flattening assembly 3 includes an upper flattening unit 31, a lower flattening unit 32, and a monitoring unit 33. The upper flattening unit 31 is mounted on the adjustment frame 2 and is moved vertically by a second drive unit. The lower flattening unit 32 is mounted on the adjustment frame 2 and is located below the upper flattening unit 31. The upper flattening unit 31 and the lower flattening unit 32 cooperate to clamp the packaging material 4. In this embodiment of the present application, the first drive unit and the second drive unit are both pneumatic cylinders, and the position of the adjustment frame 2 and the upper flattening unit 31 is changed by adjusting the overall length of the cylinders. When it is necessary to clamp the packaging material 4, the upper flattening unit 31 is moved closer to the lower flattening unit 32 to clamp packaging materials 4 of different thicknesses, thereby improving the adaptability of clamping packaging materials 4 of different thicknesses.

[0038] The upper flattening unit 31 includes a reference block 311, a mounting rod 312, and a flattening wheel 313. The reference block 311 is mounted on the adjustment frame 2 and slidably engages with the adjustment frame 2. The mounting rod 312 is horizontally mounted on the reference block 311. Two flattening wheels 313 are provided, which adapt to the ends of the mounting rod 312 and are detachably fixedly mounted on the mounting rod 312. The flattening wheels 313 and the mounting rod 312 rotate in conjunction with the flattening wheels 313. The outer circumference of the flattening wheels 313 is provided with inclined flattening edges. When the packaging material 4 passes between two adjacent flattening wheels 313, the flattening edges on the flattening wheels 313 provide a flattening force on the packaging material 4. The working principle of the flattening wheels 313 is similar to that of a threaded flattening roller. In order to reduce the possibility of deformation and bending of the mounting rod 312 over a long period of time, a reinforcing rod 314 is installed on the reference block 311. The reinforcing rod 314 and the mounting rod 312 are connected by a fixing block 315, and the structural strength of the mounting rod 312 is improved by the fixing block 315 and the reinforcing rod 314.

[0039] The monitoring unit 33 includes a vertical distance sensor 331, a horizontal distance sensor 332, and an alarm 333. Both the vertical distance sensor 331 and the horizontal distance sensor 332 are connected to the alarm 333. The vertical distance sensor 331 is used to monitor the distance signal between the upper flattening unit 31 and the lower flattening unit 32 in real time and transmit the distance signal to the alarm 333. If the distance signal between the upper flattening unit 31 and the lower flattening unit 32 is abnormal, the alarm 333 will sound an alarm.

[0040] There are multiple groups of horizontal distance measuring sensors 332. The upper flattening unit 31 and the lower flattening unit 32 are each provided with a group of horizontal distance measuring sensors 332. Each group of horizontal distance measuring sensors 332 is provided with two, and the horizontal distance measuring sensors 332 are adapted to the flattening wheel 313.

[0041] The horizontal distance measuring sensor 332 is used to monitor the distance signal between the flattening wheel 313 and the mounting rod 312, and transmit the distance signal between the flattening wheel 313 and the mounting rod 312 to the alarm 333. When the flattening wheel 313 is bent due to the mounting rod 312, resulting in an abnormality in the distance signal between the flattening wheel 313 and the mounting rod 312, an alarm is sounded through the alarm 333.

[0042] In the embodiment of the present application, the horizontal distance measuring sensor 332 and the vertical distance measuring sensor 331 are both fixedly mounted on the reinforcing rod 314 , and in the embodiment of the present application, the horizontal distance measuring sensor 332 and the vertical distance measuring sensor 331 are both infrared distance measuring sensors.

[0043] The implementation principle of an automatic feeding device for packaging cutting according to an embodiment of the present application is as follows: During the conveying process of the packaging material 4, the adjustment frame 2 adjusts the initial position of the flattening assembly 3 according to the position of the packaging material 4, so that the packaging material 4 passes through the flattening assembly 3 during the conveying process and is gradually flattened, thereby improving the convenience of correction. The upper flattening unit 31 and the lower flattening unit 32 cooperate to clamp the material, and the flattening edge on the flattening wheel 313 provides a flattening force to flatten the packaging material 4. The monitoring unit 33 monitors the distance between the flattening assemblies 3 and the distance between the flattening wheel 313 and the mounting rod 312 in real time. If the flattening wheel 313 is abnormal, an alarm 333 will be issued to ensure the stability and accuracy of the feeding process.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
