Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0032] like Figures 1 to 7 As shown, a paper box folding line processing device in one embodiment of the present invention includes: a base 1, a pressing device 2, and a kinetic energy switching device 3.

[0033] like Figures 1 to 3 As shown, a support frame 101 is fixedly mounted on the base 1 for support. A pair of first slide rails 103 are provided on the base 1, and a first slider 104 is slidably mounted on each of the first slide rails 103. A placement platform 102 is fixedly mounted on each of the first sliders 104, and the first sliders 104 drive the placement platform 102 to slide back and forth. A pair of supports 109 are provided on the base 1 for supporting and fixing the sliding rod 108. The sliding rod 108 is positioned between the supports 109 and the support frame 101. A bearing groove 105 is carved into the placement platform 102, and the bearing groove 105 engages with the pressure strip 204 to fold the edges of the cardboard box.

[0034] like Figures 1 to 3 As shown, a toothed plate 107 is provided at the bottom of the placement platform 102 for moving the placement platform 102. A lever 106 is provided on one side of the placement platform 102 for turning the rotating rod 301. A moving block 111 is slidably provided on the slide rod 108, and a first spring 110 is provided between the support 109 and the moving block 111, which plays a buffering role when the pressure plate 201 is pressed down.

[0035] like Figures 1 to 5 As shown, the pressing device 2 is mounted on the support frame 101. The pressing device 2 includes a screw 202, on which a lifting plate 209 is threadedly connected. Multiple pairs of support shafts 203 are fixedly mounted on the lifting plate 209. A pressure plate 201 is slidably mounted on the support shafts 203. The lifting plate 209 drives the support shafts 203 to move up and down, and the support shafts 203 drive the pressure plate 201 to move up and down. A second spring 212 is provided between the support shafts 203 and the inner wall of the pressure plate 201 for cushioning. A pressure strip 204 is fixedly mounted on the support shafts 203, and the pressure strip 204 engages with the bearing groove 105 to fold the edges of the cardboard box. A pair of second sliding rods 210 are provided on one side of the screw 202, and a second slider 211 is slidably mounted on the pair of second sliding rods 210. The second slider 211 slides on the second sliding rods 210. A transmission rod 215 passes through the second slider 211.

[0036] like Figures 1 to 5 As shown, a first gear 205 is fixedly mounted on the screw 202 to drive the screw 202 to rotate. The screw 202 is rotatably connected to the support frame 101, and the pressure plate 201 is slidably mounted on the slide rod 108. Both ends of the transmission rod 215 pass through the slider 211, and a drive motor 208 is mounted on one end of the transmission rod 215. Preferably, the drive motor 208 is a low-speed motor that drives the transmission rod 215 to rotate. A second gear 206 is connected to the end of the transmission rod 215 away from the drive motor 208, and the transmission rod 215 drives the second gear 206 to rotate. A third gear 207 is mounted on the side of the second gear 206 away from the screw 202 to drive the transmission shaft 213 to rotate.

[0037] like Figures 1 to 5 As shown, a drive shaft 213 is fixedly mounted on the third gear 207 to drive the fourth gear 214 to rotate. The first gear 205, the second gear 206, and the third gear 207 mesh with each other. In one state, the second gear 206 meshes with the first gear 205, and in another state, the second gear 206 meshes with the third gear 207. The drive shaft 213 is installed through the slide rod 108. The fourth gear 214 is located at the end of the drive shaft 213 away from the third gear 207. The fourth gear 214 is located in the support 109 and meshes with the gear plate 107, driving the gear plate 107 to move back and forth.

[0038] like Figures 2 to 7 As shown, the kinetic energy switching device 3 is mounted on the support frame 101. The kinetic energy switching device 3 includes a rotating shaft 311, on which an L-shaped reversing rod 306 and a control rod 307 are rotatably connected. The L-shaped reversing rod 306 is used to actuate the transmission rod 315. A U-shaped groove 310 is cut into the L-shaped reversing rod 306, and the transmission rod 215 is disposed in the U-shaped groove 310. Rotation of the L-shaped reversing rod 306 actuates the rotating rod 315, thereby driving the second slider 211 to slide on the second slide rail 210, switching the second gear 206 from the meshing state with the first gear 205 to the meshing state with the third gear 207. Both the L-shaped reversing rod 306 and the control rod 307 are provided with fixing blocks 312 for mounting a third spring 308. A third spring 308 is fixedly disposed between a pair of fixing blocks 312 for tightening the L-shaped reversing rod 306 and the control rod 307, and also provides a certain buffering effect.

[0039] like Figures 2 to 7 As shown, a pair of limiting blocks 309 are provided on both sides of the control lever 307 to limit the control lever 307. A support block 302 is provided on the support frame 101 to support the rotating rod 301. A rotating rod 301 is rotatably mounted on the support block 302, with one end of the rotating rod 301 located on one side of the control lever 307. The rotating rod 301 is used to move the control lever 307. A first pulley 303 is provided on the support 109, and a second pulley 305 is provided on the support frame 101 for the pull rope 304 to slide. The pull rope 304 is slidably mounted on the first pulley 303 and the second pulley 305. The pull rope 304 moves on the first pulley 303 and the second pulley 305. Both ends of the pull rope 304 are fixedly connected to the control lever 307 and the pressure plate 201, respectively. After the pressure plate 201 moves to a certain position, the pull rope 304 will pull the control lever 307.

[0040] Working principle: In actual use, the second gear 206 and the third gear 207 are engaged before each use. During operation, the cardboard is first placed on the placement platform 102, and then the drive motor 208 is started. The drive motor 208 drives the second gear 206 to rotate through the transmission rod 215. The second gear 206 drives the third gear 207 to rotate. The third gear 207 drives the fourth gear 214 to rotate through the transmission shaft 213. The fourth gear 214 drives the toothed plate 107 to move back and forth, causing the placement platform 102 to move horizontally towards the downward pressing device 2. After the placement platform 102 moves to a certain position, the lever 106 moves the rotating rod 301, and the rotating rod 301 rotates around the support block 302 as the axis.

[0041] At this time, the end of the rotating rod 301 that is in contact with the control rod 307 slowly moves the control rod 307 in the opposite direction to the movement of the placement platform 102. At this time, the position of the third spring 308 also slowly moves from one side of the rotating shaft 311 to the other side. When the placement platform 102 moves to the position where the bearing groove 105 is directly below the pressure bar 204, the position where the control rod 307 rotates is just enough to move the third spring 308 to the other side of the rotating shaft 311. Due to the elasticity of the third spring 308, it will tighten the L-shaped reversing rod 306 and the control rod 307 through the fixing block 312. Since the limit block 309 restricts the rotation of the control rod 307, the L-shaped reversing rod 306 will rotate around the rotating shaft 311.

[0042] At this time, the rotation of the L-shaped reversing rod 306 will pull the transmission rod 215 in the U-shaped groove 310 to move. The transmission rod 215 drives the second slider 211 to move on the second slide rail 210 towards the first gear 205. At the same time, the second gear 206 and the third gear 207 disengage. The lower placement platform 102 stops moving. The second gear 206 slowly moves towards the first gear 205. After it reaches the engagement state, the second gear 206 drives the first gear 205 to rotate. The first gear 205 drives the screw 202 to rotate. The rotation of the screw 202 causes the lifting plate 209 to move slowly downward. The lifting plate 209 drives the support shaft 203 to move slowly downward. The support shaft 203 drives the pressure plate 201 to move slowly downward.

[0043] During the downward movement, after the pressure plate 201 contacts the moving block 111, the elasticity of the first spring 110 will slow down the downward movement of the pressure plate 201. After the first spring 110 is compressed to a certain extent, the pressure plate 201 stops moving downward. At this time, the pressure plate 201 is in contact with the cardboard on the placement table 102. The screw 202 continues to drive the lifting plate 209 to move downward. After the pressure plate 201 stops moving downward, the support shaft 203 will slide downward inside the pressure plate 201. At the same time, the support shaft 203 drives the pressure strip 204 to fold the cardboard downward. At this time, the second spring 212 between the support shaft 203 and the inner wall of the pressure plate 201 plays a buffering role to prevent the cardboard from being crushed. At the same time, by absorbing the pressure of the support shaft 203, it transmits a part of the elastic force to the pressure plate 201 in the opposite direction, which can press the cardboard tightly to prevent it from running away.

[0044] After the cardboard folding line is completed, control the drive motor 208 to rotate in the direction of rotation, and slowly lift the pressing device 2. During the lifting process, the pull rope 304 is stretched from a slack state to a taut state. After being lifted to a certain position, the pressure plate 201 pulls the control rod 307 through the tension 304, and slowly moves the second gear 206 to the third gear 207. The second gear 206 disengages from the first gear 205, and the pressure plate 201 stops moving. After the second gear 206 moves to the state of engagement with the third gear 207, it drives the placement table 102 to move outward. After moving to the appropriate position, turn off the drive motor 208 and remove the cardboard.
