[0002] In the packaging box production process, it is usually necessary to print bending lines, trim edges, and perforate on flat plastic sheets. These operations are typically performed using high-frequency welding and die-cutting equipment. Traditionally, packaging boxes were manually placed one by one on the high-frequency welding and die-cutting equipment for processing, but this method is inefficient and has high labor costs. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned shortcomings in the prior art by providing a packaging box production line.

[0004] The objective of this invention is achieved through the following technical solution: a packaging box production line, comprising a feeding device, a high-frequency welding device, a die-cutting device, a waste removal device, and a unloading device arranged sequentially in the transverse direction; a transmission device is provided between the feeding device, the high-frequency welding device, the die-cutting device, the waste removal device, and the unloading device; the feeding device includes a frame; the frame is movably provided with multiple clamping mechanisms in the transverse direction; a positioning mechanism is provided at one end of the frame near the feeding device.

[0005] The beneficial effects of the present invention are as follows: The present invention uses a feeding device to transfer a flat packaging box to the positioning mechanism of the frame. After the clamping mechanism clamps the packaging box, it is moved to a high-frequency device for printing bending lines. Then, the clamping mechanism moves the packaging box to a die-cutting device for edge trimming. After the waste removal device pushes out the perforated waste, it is finally moved to an unloading device for unloading, thereby completing the automated production of the packaging box.

[0032] The present invention will be further described in conjunction with the following embodiments.

[0033] Depend on Figures 1 to 24 As can be seen, the packaging box production line described in this embodiment includes a feeding device 2, a high-frequency welding device 4, a die-cutting device 3, a waste removal device 5, and a unloading device 6 arranged sequentially in the transverse direction; wherein, the unloading device 6 can be a robot arm and a vacuum suction nozzle for unloading provided on the robot arm; a transmission device is provided between the feeding device 2, the high-frequency welding device 4, the die-cutting device 3, the waste removal device 5, and the unloading device 6; the feeding device 2 includes a frame 11; the frame 11 is movably provided with multiple clamping mechanisms 12 in the transverse direction; a positioning mechanism is provided at one end of the frame 11 near the feeding device 2. Specifically, in the packaging box production line described in this embodiment, the feeding device 2 first transfers the flat packaging box to the positioning mechanism of the frame 11. After the positioning mechanism positions the flat packaging box, the clamping mechanism 12 clamps the packaging box. Then, the clamping mechanism 12 moves the packaging box to the high-frequency device 4 for printing bending lines and generating perforations of a specific shape. Then, the clamping mechanism 12 moves the packaging box to the die-cutting device 3 for edge trimming. Then, the clamping mechanism 12 moves the packaging box to the waste removal device 5. After the waste removal device 5 ejects the perforated waste from the packaging box, the clamping mechanism 12 finally moves the packaging box to the unloading device 6 for unloading, thereby completing the automated production of the packaging box.

[0034] Depend on Figures 2 to 6As can be seen, in the packaging box production line described in this embodiment, the positioning mechanism includes a positioning seat 13 located at one end of the frame 11 near the unloading device 6, a connecting seat 14 movably mounted on the positioning seat 13, a rear positioning plate 15 located on the connecting seat 14, and a front positioning plate 16 located on the rear positioning plate 15; a rear positioning rod 151 is provided at the top of the rear positioning plate 15; a front positioning rod 161 is provided at the bottom of the front positioning plate 16; the rear positioning plate 15 is movably mounted on the connecting seat 14 in the lateral direction; the front positioning plate 16 is movably mounted on the rear positioning plate 15 in the lateral direction; the height of the front positioning rod 161 is higher than the height of the rear positioning rod 151; specifically, firstly, the loading device 2 transmits the flat packaging box to the end of the frame 11, then the clamping mechanism 12 clamps the packaging box, and the clamping mechanism 12 drives the packaging box to move sequentially to the high-frequency device 4, the die-cutting device 3, the waste removal device 5, and the unloading device 6.

[0035] In addition, before the feeding device 2 transfers the flat packaging box to the end of the frame 11, the connecting seat 14 first drives the rear positioning plate 15 and the front positioning plate 16 to descend, thereby causing the front positioning rod 161 and the rear positioning rod 151 to descend. When the feeding device 2 transfers the flat packaging box to the end of the machine, the end of the packaging box abuts against the rear positioning rod 151, and the top of the packaging box abuts against the front positioning rod 161, so that the packaging box can be accurately placed on the frame 11. In addition, in this embodiment, by moving the rear positioning plate 15 in the lateral direction to the connecting seat 14 and moving the front positioning plate 16 in the lateral direction to the rear positioning plate 15, the distance between the front positioning rod 161 and the rear positioning rod 151 can be adjusted, thereby adjusting the position of abutting against the packaging box according to user needs and enhancing adaptability.

[0036] The connecting seat 14 is provided with a first adjusting block 141; the first adjusting block 141 is provided with a first strip groove 142; the rear positioning plate 15 is provided with a first adjusting rod 143; the first adjusting rod 143 is slidably disposed in the first strip groove 142; a first screw is rotatably disposed in the first adjusting block 141; the first adjusting rod 143 is threadedly connected to the first screw; the first screw is connected to a first knob 144; the first screw is not shown in the figure. When it is necessary to adjust the position of the rear positioning plate 15, the first screw is rotated by rotating the first knob 144. Since the first screw and the first adjusting rod 143 are perpendicularly arranged and the first screw and the first adjusting rod 143 are threadedly connected, the rotation of the first screw can drive the first adjusting rod 143 and the rear positioning plate 15 to slide along the first strip groove 142.

[0037] The rear positioning plate 15 is provided with a second adjusting block 152; the second adjusting block 152 is provided with a second strip groove 153; the front positioning plate 16 is provided with a second adjusting rod 154; the second adjusting rod 154 is slidably disposed in the second strip groove 153; a second screw is rotatably disposed in the second adjusting block 152; the second adjusting rod 154 is threadedly connected to the second screw; the second screw is connected to a second knob 155; when it is necessary to adjust the position of the front positioning plate 16, the second knob 155 is rotated, thereby causing the second screw to rotate. Since the second screw and the second adjusting rod 154 are perpendicularly arranged and the second screw and the second adjusting rod 154 are threadedly connected, the rotation of the second screw can drive the second adjusting rod 154 and the front positioning plate 16 to slide along the second strip groove 153, thereby adjusting the distance between the front positioning rod 161 and the rear positioning rod 151.

[0038] The positioning seat 13 is equipped with a positioning cylinder 131; the output end of the positioning cylinder 131 is connected to the connecting seat 14; the connecting seat 14 is equipped with a positioning guide shaft 145; the positioning seat 13 is equipped with a positioning bushing 132; the positioning guide shaft 145 is slidably disposed on the positioning bushing 132. The above arrangement facilitates the driving of the connecting seat 14 to perform lifting and lowering movements.

[0039] The packaging box production line described in this embodiment includes a clamping mechanism 12 comprising a clamping seat 17 and a clamping shaft 171 rotatably disposed on the clamping seat 17; the clamping shaft 171 is arranged in a longitudinal direction; the clamping shaft 171 is provided with a plurality of clamping components; the clamping components include a clamping block 172 disposed on the clamping shaft 171, a clamping arm 173 disposed on the clamping block 172, and a clamping coil spring 174 disposed between the clamping block 172 and the clamping seat 17;

[0040] Both ends of the clamping seat 17 are provided with movable seats 175; the frame 11 is provided with a chain 111; the movable seats 175 are located on the chain 111; the above arrangement facilitates the movement of the clamping seat 17 to the processing station for processing.

[0041] The positioning seat 13 is provided with a fixing cylinder 18; the output end of the fixing cylinder 18 is provided with a fixing roller 181; the fixing roller 181 is located on the top of the movable seat 175; when the movable seat 175 moves to the bottom of the fixing roller 181, the fixing cylinder 18 drives the fixing roller 181 to descend, thereby pressing the movable seat 175 tightly, thereby fixing the position of the clamping seat 17.

[0042] The clamping seat 17 is provided with a trigger swing arm 176; the end of the trigger swing arm 176 is provided with a trigger roller 177; the positioning seat 13 is rotatably provided with a trigger shaft 19; the trigger shaft 19 is provided with a trigger connecting rod 191; the positioning seat 13 is provided with a trigger cylinder 192; the output end of the trigger cylinder 192 is connected to the trigger connecting rod 191; the trigger shaft 19 is provided with a trigger block 193 for abutting against the trigger swing arm 176. When the packaging box abuts against the front positioning rod 161 and the rear positioning rod 151, the trigger cylinder 192 starts to work, driving the trigger shaft 19 to rotate through the trigger connecting rod 191, thereby causing the trigger block 193 to press down the trigger swing arm 176, which in turn causes the clamping shaft 171 to rotate, so that the clamping arm 173 separates from the clamping seat 17. When the packaging box abuts against the front positioning rod 161 and the rear positioning rod 151, the front end of the packaging box is located at the bottom of the clamping arm 173. At this time, the trigger cylinder 192 resets, and under the reset action of the clamping coil spring 174, the packaging box is clamped between the clamping arm 173 and the clamping seat 17.

[0043] Depend on Figures 7 to 12 As can be seen, in the packaging box production line described in this embodiment, the feeding device 2 includes a feeding seat; the feeding seat is provided with a feeding mechanism in the transverse direction; one end of the feeding mechanism is provided with a feeding mechanism; the other end of the feeding mechanism is provided with a side-aligning mechanism; the side-aligning mechanism includes a push-pull shaft 23 rotatably disposed on the feeding seat and a first push-pull assembly disposed on one side of the feeding seat; the first push-pull assembly includes a first push-pull seat 24 disposed on one side of the feeding seat, a first push-pull wheel 241 rotatably disposed on the first push-pull seat 24, and a first limiting plate 244 disposed on the first push-pull seat 24; the first push-pull wheel 241 is rotatably disposed on the first push-pull seat 24 in the longitudinal direction; the first push-pull assembly also includes a first push-pull linkage component; the push-pull shaft 23 drives the first push-pull wheel 241 to rotate through the first push-pull linkage component;

[0044] Specifically, the feeding mechanism first places the flat outer packaging box on the feeding mechanism. When the feeding mechanism moves the packaging box to the opposite side mechanism, the packaging box reaches the position of the first push-pull wheel 241. The push-pull shaft 23 rotates and drives the first push-pull wheel 241 to rotate through the first push-pull linkage, so that the packaging box can move in the longitudinal direction and move to abut against the first limit plate 244. At the same time, the feeding mechanism delivers the packaging box, thereby ensuring that the packaging box can be delivered in alignment and ensuring the processing quality of the packaging box.

[0045] The first push-pull linkage includes a first cylindrical cam 25 disposed on the push-pull rotating shaft 23, a first cam roller 242 disposed on the first push-pull wheel 241, and a first tension spring 243 disposed between the first push-pull wheel 241 and the first push-pull seat 24; the first cylindrical cam 25 is provided with a first cam groove; the first cam roller 242 abuts against the first cam groove through the first tension spring 243; the first cam groove includes an ascending groove 251, a descending groove 252, and a flat groove 253; one end of the ascending groove 251 is connected to one end of the flat groove 253; the other end of the flat groove 253 is connected to one end of the descending groove 252; the other end of the descending groove 252 is connected to the other end of the ascending groove 251; when the push-pull rotating shaft 23 rotates... When the mechanism is activated, it drives the first cylindrical cam 25 to rotate. Under the action of the first tension spring 243, the first cam roller 242 moves on the first cam groove. When the push-pull shaft 23 rotates clockwise, the first cam roller 242 rises along the rising groove 251, thereby allowing the first push-pull wheel 241 to rotate towards the first limiting plate 244, thus moving the packaging box towards the first limiting plate 244. When the first cam roller 242 moves to the flat groove 253, the packaging box has passed through the first push-pull seat 24 and is being fed to external equipment. During the transfer between two adjacent packaging boxes, the first push-pull wheel 241 is reset through the descending groove 252, thus waiting for the next packaging box to arrive. The opposite side mechanism also includes a second push-pull assembly on the other side of the loading seat.

[0046] The second push-pull assembly includes a second push-pull seat 26 located on the other side of the loading seat, a second push-pull wheel 261 rotatably mounted on the second push-pull seat 26, and a second limiting plate 264 located on the second push-pull seat 26; the second push-pull wheel 261 is rotatably mounted on the second push-pull seat 26 in the longitudinal direction; the second push-pull assembly also includes a second push-pull linkage member; the push-pull rotating shaft 23 drives the second push-pull wheel 261 to rotate through the second push-pull linkage member; the first limiting plate 244 is located at the end of the first push-pull seat 24 away from the second push-pull seat 26; the second push-pull assembly includes a second push-pull linkage member; the second push-pull rotating shaft 23 drives the second push-pull wheel 261 to rotate through the second push-pull linkage member; the second ... push-pull linkage member 261 drives the second push-pull wheel 261 to rotate through the second push-pull linkage member; the second push-pull linkage member 261 drives the second push-pull wheel 261 to rotate through the second push-pull linkage member; the second push-pull linkage member 261 drives the second push-pull wheel 261 to rotate through the second push-pull linkage member; the second push-pull linkage member 261 drives the second push-pull wheel 261 to rotate through the second push-pull linkage member; the second push-pull linkage member 261 drives the second push-pull wheel 261 to rotate The second limiting plate 264 is disposed at the end of the second push-pull seat 26 away from the first push-pull seat 24; the second push-pull linkage component includes a second cylindrical cam 265 disposed on the push-pull rotating shaft 23, a second cam roller 262 disposed on the second push-pull wheel 261, and a second tension spring 263 disposed between the second push-pull wheel 261 and the second push-pull seat 26; the second cylindrical cam 265 is provided with a second cam groove; the second cam roller 262 abuts against the second cam groove through the second tension spring 263; the first cam groove and the second cam groove are mirror-symmetrically arranged.

[0047] Specifically, since the first cam groove and the second cam groove are mirror-symmetrically arranged, when the push-pull shaft 23 rotates clockwise, it can drive the second push-pull wheel 261 to rotate away from the second limit plate 264, thereby further driving the packaging box to move towards the first limit plate 244.
