However, since they are all existing technologies, their structural principles will not be elaborated here.

[0046] The threaded screw 109 is connected to the motor, and the threaded screw 109 is connected to the ear box 101 through a thread, so that the threaded screw 109 rotates to drive the ear box 101 to rise and fall, thereby adjusting the height of the ear box 101.

[0052] It should be noted that the cylinder 202 is a prior art, and its structural principle is not described in detail here. A roller is provided in the inner cavity of the glue box 207 to roll the glue evenly, so as to facilitate the gluing of the glue cylinder 206. The rope wheel 214 provided at the lower part of the cross bar 200 and the rope wheel 214 provided in the inner cavity of the L-shaped telescopic plate 211 act as a folding angle, so that the wire rope 212 can be connected with several rope wheels 214 to achieve a turning direction, thereby achieving the pressing plate 20 When moving downward, the steel wire rope 212 is pulled, and then the telescopic end of the L-shaped telescopic plate 211 is driven by the steel wire rope 212 to move backward, and then the adhesive tube 206 is released to avoid obstruction of the adhesive tube 206 when moving downward. When the pressing plate 205 rises, the spring fixed to the telescopic end at the bottom of the inner cavity of the L-shaped telescopic plate 211 enables the telescopic end of the L-shaped telescopic plate 211 to push the arc-shaped leakage groove 213 back to the lower end of the adhesive tube 206, and continuously collect the glue dripping from the adhesive tube 206.

The trapezoidal connecting rod 204 moves downward, so that the trapezoidal connecting rod 204 can squeeze the spring B208 while descending along the guide rod 203, and drive the pressure plate 205 and the glue cylinder 206 to descend, and then glue the tongue on the carton. When the pressure plate 205 moves downward, it will pull the steel wire rope 212, and then the steel wire rope 212 will pull the telescopic end of the L-shaped telescopic plate 211 to move backward, and then drive the arc-shaped leakage groove 213 fixed to the telescopic end of the L-shaped telescopic plate 211 to move backward, making room for the glue cylinder 206 for gluing.

[0054] Reference Figure 1 , Figure 5-Figure 8 Two folding mechanisms 300 are arranged at the lower part of the outer frame 100, and the two folding mechanisms 300 are the same in structure and installation method, and the folding mechanism 300 includes a vertical support plate 301 slidably arranged at the bottom of the outer frame 100, and a reciprocating screw rod 302 is rotatably arranged in the middle of the surface of the vertical support plate 301 located on one side of the outer frame 100, and the lower end of the reciprocating screw rod 302 is fixedly connected to the output end of the synchronous motor 317, and the synchronous motor 317 is fixedly arranged on the vertical support plate 301. On one side of the bottom, the reciprocating screw rod 302 threadedly passes through the middle of one end of the square pressure rod 303, and the square pressure rod 303 is the same size as the carton, so that the four corners of the square pressure rod 303 can match the four corners of the folded paper shell, so that it is convenient for the square pressure rod 303 to fold the carton, and two vertical slide grooves are opened on the vertical support plate 301, and the spacing between the two slide grooves is consistent with the width of the square pressure rod 303, so that the square pressure rod 303 can slide and limit each other with the vertical support plate 301.

[0055] Reference Figure 1 , Figure 5-Figure 8 Two back plates 304 are arranged on the surface of one side of the vertical support plate 301 away from the reciprocating screw rod 302, and the two back plates 304 are rotatably connected to the back plate 304 through a rotating shaft arranged on the side of the lower end away from the inclined fixed plate 312, and the two back plates 304 have the same structure and are respectively located on both sides of the square pressure rod 303, and are staggered with each other up and down, and an arc strip 305 is fixedly arranged on one side of the surface of the two back plates 304, and the outer arc surface of the arc strip 305 is arranged to abut against one side surface of the spring telescopic rod 306, and an upper slide plate 307 is rotatably arranged on the upper end of the spring telescopic rod 306, and an inclined slide plate 308 is transferred to the lower end of the spring telescopic rod 306.

[0057] Reference Figure 1 , Figure 5-Figure 8 , and a lower limit plate 313 is disposed at the lower end of the back plate 304, and a spring D314 is fixedly disposed on the surface of one side of the lower limit plate 313 located at the limit groove 309, and the other end of the spring D314 is fixedly connected to one side of the lower end of the back plate 304, so that the spring D314 can pull the back plate 304 back after the back plate 304 rotates, and a cylinder 311 is fixedly disposed at the bottom of one side of the reciprocating screw rod 302 on the vertical support plate 301, and the cylinder 311 and the outer frame 100 are fixedly disposed with each other. , and at the lower part of the vertical support plate 301 located at the upper part, a rotating plate 316 is rotatably arranged in the middle part of the back plate 304, and the upper end of the rotating plate 316 and the upper slide plate 307 located at the lower part are abutted against each other, so that the upper slide plate 307 at the lower part is pushed out to abut the upper end of the upper rotating plate 316, and then the lower end of the rotating plate 316 is pushed to rotate and approach the side of the back plate 304, so as to realize that the upper slide plate 307 at the lower end pushes the tongue on the last piece of the folded carton to press down and adhere to the carton.

[0058] It should be noted that the reciprocating screw 302, the cylinder 311 and the synchronous motor 317 are all prior arts, and their structural principles are not elaborated in detail here. The reciprocating screw 302 is connected to the synchronous motor 317, so that the reciprocating screws 302 on both sides can rotate synchronously, thereby driving the two square pressure rods 303 to move synchronously, and the inclined slide plate 308 is set to a "V" shape, and the upper end inclined surface of the inclined slide plate 308 can abut against the cross bar 200 at the lower end of the square pressure rod 303, so that when the square pressure rod 303 moves downward, it can push the inclined slide plate 308 to move to the lower section of the spring telescopic rod 306, and the middle part of the lower end surface of the upper limit plate 315 and the middle part of the upper end surface of the upper slide plate 307 are respectively provided with a T-shaped slide bar 103 and a T-shaped slide groove, so that the upper slide plate 307 will not fall off the upper limit plate 315 due to gravity.

[0059] The vertical support plate 301 is pushed by cylinder 2 311, and then the distance between the two square pressure rods 303 is adjusted according to the length of the carton to ensure that it is consistent with the length of the carton, so that the carton can be folded, and the rotation of the reciprocating screw rod 302 drives the reciprocating movement of the square pressure rod 303. When the square pressure rod 303 moves downward, the inclined slide plate 308 can be pushed into the limiting groove 309, so that the inclined slide plate 308 pushes the lower end of the spring telescopic rod 306 and squeezes the spring C310 toward the side of the inclined fixed plate 312. When the spring telescopic rod 306 is pushed by the inclined slide plate 308, the middle part of it will abut against the arc bar 305, and under the action of the arc bar 305, it will push the upper slide plate 307 on the upper part, and the upper slide plate 307 will be pushed out along the upper limit plate 315 under the abutment and limiting action of the upper limit plate 315, and abut against the unfolded paper shell part of the upper part of the carton carried by the square pressure rod 303, and then fold the unfolded part.

[0060] The upper slide plate 307 at the bottom will push the upper part of the rotating plate 316 after folding the unfolded part, so that the rotating plate 316 rotates, and abuts and presses the tongue on the carton, thereby sticking the tongue to the carton together. When the square pressure rod 303 moves to the lower end of the back plate 304, the cylinder 311 separates the folding mechanisms 300 on both sides, thereby separating the square pressure rod 303 from the stuck carton and causing it to fall onto the conveyor belt or collection bin for collection.

[0061] At this time, the square pressure rod 303 will return to its original path under the action of the reciprocating screw rod 302, and when the square pressure rod 303 moves upward, it will push the inclined slide plate 308 and drive the entire back plate 2 304 to rotate, so that the square pressure rod 303 can pass through the upper part of the return back plate 2 304.

[0062] The implementation principle of the tongue gluing device for a corrugated cardboard box in the embodiment of the present application is as follows: the ear box 101 is driven to rise and fall by rotating the threaded screw 109, and the ear box 101 is guided and limited by two guide rods 108, so as to adjust the height of the ear box 101, and the rack 106 is driven to move back and forth by rotating the gear 105, thereby driving the side plate 104 and the T-shaped slide bar 103 to maintain linear reciprocating movement under the limiting and guiding action of the guide groove 102, and the movement of the side plate 104 can drive the cross bar 200 to move synchronously.

[0063] Thereby, the cross bar 200 can simultaneously drive the fixed block 201, the cylinder 1 202, the guide rod 203 and the back plate 1 210 to move forward and backward synchronously, and then the trapezoidal connecting rod 204 and the pressure plate 205 can move synchronously, so that the pressure plate 205 can move with the glue tube 206 to the specified glue application position, and when the glue tube 206 moves to the specified position, the cylinder 1 202 can drive the trapezoidal connecting rod 204 to move downward, so that the trapezoidal connecting rod 204 can squeeze the spring B208 while descending along the guide rod 203, and drive the pressure plate 205 and the glue tube 206 to descend, and then glue the tongue on the carton, and when the pressure plate 205 moves downward, it will pull the wire rope 212, and then the wire rope 212 will pull the telescopic end of the L-shaped telescopic plate 211 and the arc-shaped leakage groove 213 to move backward, making room for the glue tube 206 for gluing.

[0064] The vertical support plate 301 is pushed in advance by cylinder 2 311, and then the distance between the two square pressure rods 303 is adjusted by the length of the carton. When the carton that has been glued is transported to the lower end of the square pressure rod 303, the rotation of the reciprocating screw rod 302 drives the square pressure rod 303 to move downward, and then the carton is preliminarily folded along the dividing line of the carton. When the square pressure rod 303 moves down and abuts against the inclined slide plate 308, the inclined slide plate 308 will be pushed into the limiting groove 309, and then the inclined slide plate 308 pushes the lower end of the spring telescopic rod 306 to make the middle part of the spring telescopic rod 306 abut against the arc strip 305, and then the upper slide plate 307 is pushed out along the upper limit plate 315, and abuts against the unfolded paper shell part of the upper part of the carton carried by the square pressure rod 303, and then the unfolded part is folded.

[0065] When the square pressure rod 303 carries the carton to squeeze the lower inclined slide plate 308, the spring telescopic rod 306 and the upper slide plate 307, the upper slide plate 307 will fold the unfolded part and push the upper part of the rotating plate 316 to rotate the rotating plate 316, and abut and press against the tongue on the carton, thereby sticking the tongue to the carton together. When the square pressure rod 303 moves to the lower end of the back plate 304, the cylinder 311 separates the folding mechanisms 300 on both sides, thereby separating the square pressure rod 303 from the stuck carton and causing it to fall onto the conveyor belt or collection bin for collection.

[0066] At the same time, the square pressure rod 303 will return to its original path under the action of the reciprocating screw rod 302, and during the returning process, the square pressure rod 303 will push the inclined slide plate 308 upward and drive the entire back plate 2 304 to rotate, thereby allowing the square pressure rod 303 to pass through the upper part of the return back plate 2 304.

[0067] The above are only optional embodiments of the present disclosure and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
