[0019] The driving assembly includes an electric slide rail 101, an electric slider 102, an electric slide rail 2 103, an electric slider 2 104 and a telescopic cylinder 105; two electric slide rails 101 are bolted to the fixed frame 1; each electric slide rail 101 is slidably connected to an electric slider 102; all electric sliders 102 are fixedly connected to an electric slide rail 2 103; the electric slide rail 2 103 is slidably connected to the electric slider 2 104; the electric slider 2 104 is fixedly connected to the telescopic cylinder 105, and the telescopic end of the telescopic cylinder 105 is fixedly connected to the laser cutting head 2, and the laser cutting head 2 is driven to move up and down through the telescopic cylinder 105.

[0020] Two slide grooves three 10901 are provided on the support plate one 109; an electric slider three 11001 is slidably connected in each slide groove three 10901; each electric slider three 11001 is rotatably connected to the support plate two 110; the electric slider three 11001 is connected to the support plate two 110 via an electric rotating rod 11002.

[0021] It also includes a collecting frame 114; the collecting frame 114 is arranged on the supporting plate 109; and the collecting frame 114 is connected with a connecting pipe 11401.

[0022] It also includes an anti-laser cloth 115; the collection frame 114 is divided into two chambers by a partition 116, the chamber located on the lower side is used to collect cutting debris and waste pieces, and a plurality of collection slots are opened on the partition 116; each collection slot is provided with an anti-laser cloth 115.

[0023] The partition plate 116 is wavy, and the wavy plates on the left and right sides of the collecting slot are inclined downward toward the collecting slot to ensure that the collected cutting debris and waste sheets can flow smoothly into the collecting slot.

[0024] The surface of the first fixing plate 107 is polished to reduce the friction when the first fixing plate 107 contacts the carton 100 , thereby avoiding scratching or wearing the surface of the carton 100 .

[0025] The present invention takes the side where the second slide groove 1002 is located as the front side, and the side where the first slide groove 1001 is located as the rear side. The carton 100 to be cut is placed on the fixed frame 1. At this time, the driving member 106 is driven by the electric slider to slide along the slide groove 1001 and the second slide groove 1002 to the left side of the present invention, and the output end of the driving member 106 is driven to move toward the carton 100. When the first fixed plate 107 is in contact with the surface of the carton 100, the driving member 106 is stopped from moving. The two first fixed plates 107 fix the two side walls of the carton 100. Then, the driving member 106 is driven by the electric slider fixed at its fixed end to slide along the slide groove 1001 and the second slide groove 1002 to the right side of the present invention, so that the carton 100 moves to Figure 1In the position shown, it should be noted that at this time, the support plate 109 is driven by the output end of the driving member 2 108 to be located on the right side of the present invention.

[0026] After the carton 100 is placed, the support plate 1 109 and the support plate 2 110 are as shown in FIG. Figure 6 As shown, the electric slider 11001 then slides outward along the slide slot 10901, driving the support plate 110 to extend outward, so that the support plate 110 is as shown in FIG. Figure 7 As shown, the output end of the second driving member 108 is driven to drive the second support plate 110 to approach the carton 100 and insert it into the carton 100. Before the second support plate 110 is inserted into the carton 100, the electric rotating rod 11002 is driven by the built-in rotating motor of the electric rotating rod 11002 to drive the free ends of the two second support plates 110 to close to the middle, so that the insertion end becomes narrower, which is convenient for the second support plate 110 to be inserted into the carton 100, solving the problem that the second support plate 110 needs to support the carton 100 and needs to fit the carton 100. The inner wall makes it difficult to insert the support plate 110 into the carton 100; after the support plate 110 is inserted into the carton 100, the electric rotating rod 11002 is driven to drive the free ends of the two support plates 110 to rotate outward, so that the two support plates 110 are parallel to each other and fit the inner wall of the carton 100, and then the output end of the driving member 108 is driven to continue to move into the carton 100, so that the support plate 109 is inserted into the carton 100, and the support plate 109 and the two support plates 110 are in the carton 100 as shown in FIG. Figure 6 As shown, a stable internal support is provided to the carton 100 to prevent the carton 100 from tilting, thereby ensuring the accuracy of the cutting pattern by the laser cutting head 2.

[0027] After the support plate 109 and the two support plates 110 provide stable internal support for the carton 100, the electric slider 102 is driven to slide on the electric slide rail 101, so that the electric slider 102 drives the electric slide rail 2 103 to move forward or backward, and the electric slider 104 slides on the electric slide rail 103, so that the electric slider 104 drives the telescopic cylinder 105 to move left or right, and when cutting, the telescopic cylinder 105 is driven to drive the laser cutting head 2 to move downward, so that the lower end of the laser cutting head 2 is close to the cutting surface of the carton 100, thereby controlling the laser cutting head 2 to move along the predetermined cutting path to complete the cutting of the carton. 100 is cut, but when the pattern is cut on the cutting surface of the carton 100, the surrounding of the pattern will be cut off to form a hollow, resulting in a lack of support connection in the middle part that is not cut off, causing the cutting surface of the carton 100 to easily sag and deform downward, which may cause the subsequent cutting position to deviate or the waste paper to be connected to the cutting surface cardboard of the carton 100 without being completely cut. Therefore, after the two support plates 110 and the support plate 1 109 support the carton 100, before the laser cutting head 2 cuts the carton 100, the winding box 111 is driven to release the internally wound support net 113, and the wire box 112 is driven to rewind the released wire, so that the support net 113 is released from the Figure 7 As shown, the state of being wound by the winding box 111 becomes Figure 6 In the state shown, the support provides uniform support force on the lower side of the cut surface of the carton 100, preventing the cut surface from being deformed due to excessive hollow parts, ensuring that the laser cutting head 2 can cut accurately, and reducing the situation where incomplete cutting or waste paper is connected to the cut surface cardboard of the carton 100; it should be noted that the support net 113 is woven with aramid fiber, and cooperates with the tension sensor to adjust the winding and unwinding speeds of the winding box 111 and the wire box 112 in real time.

[0028] After the carton 100 is cut, the waste paper pieces produced by the cutting cannot fall off and remain in the hollow pattern of the cutting surface due to the interception of the supporting net 113. Therefore, before rolling up the supporting net 113, an electric slider is provided on the wire box 112, which is located in the slide groove 11003. The electric slider is first driven to drive the wire box 112 to slide downward, so that the supporting net 113 is inclined, and at the same time, the winding box 111 is driven to roll up the supporting net 113, so that the waste paper pieces fall along the inclined supporting net 113 into the collection frame 114 on the lower side thereof. In the process of the winding box 111 rolling up the supporting net 113, a cleaning strip 11101 is provided on the winding box 111 to clean the rolled supporting net 113. After the supporting net 113 is rolled up, the winding box 111 is driven to slide upward, and at the same time, the winding box 111 rolls up the excess wire. In addition, considering that smoke will be generated when the laser cutting head 2 cuts the cut surface of the carton 100, before cutting, the connecting pipe 11401 is connected to an external exhaust device so that the smoke generated during cutting can be collected by the collecting frame 114. Considering that the collecting frame 114 contains previously cut and collected waste paper pieces, when the laser cutting head 2 cuts the carton 100, the laser will penetrate the cut surface of the carton 100 and irradiate into the collecting frame 114. In order to prevent the laser from irradiating the waste paper pieces from the collecting slot and igniting the waste paper pieces, an anti-laser cloth 115 is provided above the collecting slot. The anti-laser cloth 115 is made of a multi-layer composite flame-retardant material, which can effectively block scattered lasers and prevent the waste paper pieces from being ignited.

[0029] Example 2 On the basis of Example 1, Fig.10 As shown, it also includes a driving member 3 201, a second fixed plate 202 and a detection plate 203; an electric slider 2 104 is also slidably connected to the electric slide rail 2 103; the driving member 3 201 is fixedly connected to the electric slider 2 104, and the driving member 3 201 is an electric push rod; the second fixed plate 202 is fixedly connected to the output end of the driving member 3 201, and an ultrasonic sensor is installed on the second fixed plate 202; the second fixed plate 202 is provided with a detection plate 203, and the detection plate 203 is provided with pattern protrusions with the same position and size as the pattern when the carton 100 is laser cut.

[0030] The second fixing plate 202 is detachably connected to the detection plate 203, so that the detection plate 203 can be replaced after the pattern of the carton 100 is changed during laser cutting.

[0031] A slide groove five 10902 is provided on the support plate one 109 ; an electric slider four 11402 is fixedly connected to the collection frame 114 ; the electric slider four 11402 slides in the slide groove five 10902 .

[0032] After the support net 113 is rolled up, some waste paper pieces may be stuck in the hollow holes and difficult to fall off. In order to solve this problem, first drive the electric slider 4 11402 to drive the collection frame 114 to slide upward along the slide groove 5 10902, so that the upper side of the collection frame 114 is attached to the lower side of the cut surface of the carton 100, and drive the collection frame 114 to actively suck the stuck waste paper pieces through the external suction device and suck away the waste paper pieces collected in the collection frame 114. At the same time, drive the electric slider 2 104 to drive the telescopic cylinder 1 105 and the driving member 3 201 to move to the right, so that the driving member 3 201 drives the second fixed plate 202 to be located above the carton 100, and then drive the output end of the driving member 3 201 to drive the second fixed plate 202 to move downward, so that the pattern protrusion of the detection plate 203 passes through the pattern hollow part of the cut surface of the carton 100, and cooperate with the suction device to further clean up the stuck waste paper pieces. After cleaning, an ultrasonic sensor is installed on the second fixed plate 202. When the pattern convex block passes through the pattern hollow part, the ultrasonic sensor emits ultrasonic waves and receives reflected waves. By analyzing the frequency, amplitude, phase and other information of the reflected wave, the distance and position relationship between the pattern convex block and the pattern hollow part are determined. If the characteristics of the reflected wave meet the preset matching standard, it means that the pattern convex block and the pattern hollow part are completely matched, so as to detect the cutting quality of the laser cutting head 2 without manual inspection, and realize intelligent processing.
