[0012] Preferably, the method for using the drying device for corrugated box production comprises the following steps: S1: The push plate drives the two connecting rods to move the sliding frame downward synchronously.

The downward movement of the push plate causes the adjusting roller to contact the upper surface of the corrugated paper, and the thickness of the corrugated paper between the driving roller and the adjusting roller can be detected; S2: The steel belt moves at the axis of the active sliding cone disc and the active fixed cone disc, so that the steel belt between the driving wheel and the driven wheel can achieve low speed and high torque, which reduces the speed of the driven wheel.

The pulley slides in the inclined groove and drives the pressing frame to slide on the slide rail, so that the rolling roller on the pressing frame plays a rolling role when processing the surface of the corrugated paper.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by pushing the plate downward to make the adjusting roller contact the upper surface of the corrugated paper, the thickness of the corrugated paper between the driving roller and the adjusting roller can be detected, thereby facilitating the subsequent driving device to adjust the speed of the conveyor belt.

[0014] In the present invention, the rotation speed of the transmission roller is adjusted by the driven wheel, so that corrugated paper with different flute heights can quickly pass through the drying box under the drive of the conveyor belt during the drying process, thereby preventing the corrugated paper from staying in the drying box for too long during the drying process, which may cause cracking and warping on its surface. According to the sliding frame detecting the flute height of the corrugated paper, the driven wheel is used to adjust the rotation speed of the transmission roller through the driving device, so as to realize the residence time of corrugated paper with different flute heights in the drying box.

[0015] In the present invention, the pressing part can accurately press the surface of the corrugated paper according to the different heights of the corrugated paper, which can avoid excessive pressure on the corrugated paper when pressed, causing the corrugated paper to deform during the drying process, thereby achieving adaptive pressing adjustment during the drying process of corrugated paper with different flute heights.

[0016] In the present invention, when rolling A-corrugated paper, the moving distance of the moving rod becomes shorter, and the pulley is in the oblique side of the inclined groove. Then, when the moving rod moves up and down, the pulley slides in the inclined groove and drives the pressing frame to slide on the slide rail, so that the rolling roller on the pressing frame plays a rolling role when processing the surface of the corrugated paper, thereby avoiding the curling of the upper surface of the corrugated paper during the drying process.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] See also Figures 1 to 9 The present invention provides a technical solution: a drying device for corrugated cardboard box production, comprising a drying box 1, a conveyor belt 11 is provided in the drying box 1, a dryer 12 is provided on the top of the drying box 1 facing the conveyor belt 11, the drying box 1 is provided with a conveying device 2 capable of measuring the thickness of corrugated paper at the conveying end of the conveyor belt 11, a shell 13 is fixedly connected to the outer wall of the drying box 1, a driving device 3 connected to the shaft of the conveyor belt 11 is provided in the shell 13, the conveying device 2 is transmission-connected to the driving device 3, and a pressing device 4 for assisting in drying the corrugated paper is provided on the inner wall of the drying box 1 facing the conveyor belt 11.

[0021] In this embodiment, the conveying device 2 includes a conveying frame 21 fixedly connected to the outer wall of the drying box 1, the conveying frame 21 is set at the conveying end of the conveyor belt 11, the top of the conveying frame 21 is fixedly connected to a pushing electric cylinder 22, the telescopic end of the pushing electric cylinder 22 is fixedly connected to a pushing plate 23, and a corresponding slide 24 is opened on the conveying frame 21, and a sliding frame 25 is slidably connected in the two slides 24. An adjusting roller 26 is rotatably connected between the two sliding frames 25, and the tops of the two sliding frames 25 are provided with a connecting rod 27 slidably connected to the conveying frame 21, and the connecting rod 27 is fixedly connected to the bottom of the pushing plate 23, and a driving roller 28 is rotatably connected to the conveying frame 21 below the adjusting roller 26. The driving roller 28 is flush with the surface of the conveyor belt 11, and the corrugated paper is between the adjusting roller 26 and the driving roller 28 and moves toward the conveyor belt 11; The corrugated paper passes between the adjusting roller 26 and the driving roller 28, and the pushing electric cylinder 22 is provided to drive the pushing plate 23 to move downward, and the pushing plate 23 drives the two connecting rods 27 to make the sliding frame 25 move downward synchronously. When the sliding frame 25 moves downward, it drives the adjusting roller 26 to press the corrugated paper conveyed on the driving roller 28. Under the restriction of the driving roller 28 and the adjusting roller 26, the corrugated paper is moved toward the conveyor belt 11 by the rotation of the driving roller 28, so that the corrugated paper is transported on the conveyor belt 11 and dried through the drying box 1. The downward movement of the pushing plate 23 makes the adjusting roller 26 contact with the upper surface of the corrugated paper, and the thickness of the corrugated paper between the driving roller 28 and the adjusting roller 26 can be detected, so that the subsequent driving device 3 can adjust the speed of the conveyor belt 11.

[0022] In this embodiment, the driving device 3 includes a driving wheel 31, a driven wheel 32, a steel belt 34 and a driving motor 35. The driving motor 35 is fixedly connected to the inner wall of the housing 13. The main shaft of the driving motor 35 is axially connected to the driving wheel 31. The steel belt 34 is sleeved between the driving wheel 31 and the driven wheel 32. The driving wheel 31 includes a driving card shaft 311 rotatably connected to the housing 13. The main shaft of the driving motor 35 is axially connected to the driving card shaft 311. An active fixed cone disc 312 is fixedly connected to the drive card shaft 311, and an active sliding cone disc 313 is also spline-slidingly connected to the drive card shaft 311. The conical surfaces of the active fixed cone disc 312 and the active sliding cone disc 313 are arranged opposite each other. An annular groove 314 is formed on the active sliding cone disc 313, and a limit frame 315 is rotatably connected in the annular groove 314. A connecting plate 316 is fixedly connected to the outer wall of one of the sliding frames 25, and an articulated frame 317 is hingedly connected between the connecting plate 316 and the limit frame 315. The drive card shaft 311 is in transmission connection with the drive roller 28; The driven wheel 32 includes a driven card shaft 321 rotatably connected to the housing 13, a driven fixed cone disc 322 is fixedly connected to the driven card shaft 321, and a driven sliding cone disc 323 is splined and slidably connected to the driven card shaft 321. The conical surfaces of the driven fixed cone disc 322 and the driven sliding cone disc 323 are arranged opposite to each other, and a pressure spring 324 is sleeved on the driven card shaft 321. The driven card shaft 321 is also fixedly connected to a driven gear 325, and the two ends of the pressure spring 324 are respectively connected to the end faces of the driven sliding cone disc 323 and the driven gear 325. Two transmission rollers 33 are also rotatably connected to the inner wall of the drying box 1. The conveyor belt 11 is sleeved on the two transmission rollers 33, and one of the transmission rollers 33 is transmission-connected to the driven card shaft 321. The main shaft of the driving motor 35 is connected to the driving card shaft 311, so that the driving card shaft 311 can drive the driving roller 28 to rotate, so that the corrugated paper between the adjusting roller 26 and the driving roller 28 is transported. When the electric cylinder 22 drives the sliding frame 25 to move, one of the sliding frames 25 will drive the connecting plate 316 to move downward. When the connecting plate 316 moves downward, the limiting frame 315 will move linearly on the driving card shaft 311 through the hinge frame 317. Since the limiting frame 315 is connected to the active sliding cone 313 are connected to each other in a rotational manner, thereby causing the active sliding cone disc 313 to move linearly on the driving card shaft 311, thereby increasing the distance between the active sliding cone disc 313 and the active fixed cone disc 312. The steel belt 34 moves at the axis of the active sliding cone disc 313 and the active fixed cone disc 312, so that the steel belt 34 between the active wheel 31 and the driven wheel 32 achieves low speed and high torque, reducing the speed of the driven wheel 32. The pressure spring 324 causes the driven fixed cone disc 322 and the driven sliding cone disc 32 to move linearly on the driving card shaft 311, thereby increasing the distance between the active sliding cone disc 313 and the active fixed cone disc 312. The steel belt 34 between 3 can adapt to the adjustment of the driving wheel 31, and the speed of the driven wheel 32 is adjusted by the moving position of the sliding frame 25. Corrugated paper is generally divided into four categories: A flute, C flute, B flute and E flute. The flute heights of the four different types of corrugated paper are different. When drying, the drying time of the corrugated paper can be adjusted by different transportation times of A flute, C flute, B flute and E flute in the drying box 1 and controlling the size of the wind speed in the drying box 1. Due to the different flute heights of A flute, C flute, B flute and E flute, the drying time of the corrugated paper can be adjusted by controlling the wind speed in the drying box 1. The driven wheel 32 adjusts the rotation speed of the transmission roller 33 so that the corrugated paper with different flute heights can quickly pass through the drying box 1 under the drive of the conveyor belt 11 during the drying process, thereby preventing the corrugated paper from staying in the drying box 1 for too long during the drying process, which may cause cracking and warping on its surface. According to the detection of the flute height of the corrugated paper by the sliding frame 25, the driven wheel 32 adjusts the rotation speed of the transmission roller 33 through the driving device 3, thereby realizing the time that the corrugated paper with different flute heights stays in the drying box 1.

[0023] The cam 42 is connected to the rack 46 by a screw thread 46 which is fixed to the rack 46 and is engaged with the gear 42 and the gear 43 which is engaged with the gear 43. When the driven wheel 32 rotates, the driven wheel 32 causes the driven clamping shaft 321 to rotate, which can drive the driven gear 325 to rotate. The rotation of the driven gear 325 causes the rotating gear 43 to rotate synchronously. The rotating gear 43 drives the rotating disk 44 to move in a circle through the rotating rod 42. When the rotating disk 44 performs a circular motion, the rotating frame 45 eccentrically set on the rotating disk 44 will intermittently pull the seesaw 47 to move. The arc groove 49 on the seesaw 47 is limited by the clamping rod 410. The clamping rod 410 on the bracket 48 is regarded as the bracket 48 of the seesaw 47. Then, when the seesaw 47 is deflected under the drive of the rotating frame 45, with the clamping rod 410 as the fulcrum, the other end of the seesaw 47 will drive the moving rod 46 to move longitudinally on the support frame 41. The pressing member 5 provided on the moving rod 46 can intermittently press the corrugated paper on the conveyor belt 11 during the drying process, thereby accelerating the evaporation of water in the corrugated paper and avoiding the curling of the corrugated paper during the drying process.

[0024] In this embodiment, the pressing device 4 also includes a screw rod 411 rotatably connected to the support frame 41, and the end of the screw rod 411 is fixedly connected to a rotating gear 412, and an outer wall of one of the sliding frames 25 is fixedly connected to an adjustment rack 413 that meshes with the rotating gear 412, and the adjustment rack 413 is slidably connected to the inner wall of the drying box 1, and an adjustment block 414 is spirally connected to the screw rod 411, and the adjustment block 414 is slidably connected to the support frame 41, and a positioning rod 415 is fixedly connected to the outer wall of the adjustment block 414, and a positioning groove 416 is opened on the bracket 48, and the positioning rod 415 extends toward the positioning groove 416; The downward movement distance of the sliding frame 25 corresponds to the height of the corrugated paper. When the sliding frame 25 moves, the adjusting rack 413 on the sliding frame 25 drives the rotating gear 412 to rotate. The rotation of the rotating gear 412 causes the screw rod 411 to rotate. When the screw rod 411 rotates, it drives the adjusting block 414 to slide on the support frame 41. When the positioning rod 415 on the adjusting block 414 contacts the positioning groove 416 on the bracket 48, the positioning rod 415 can drive the bracket 48 to deflect on the support frame 41. When the bracket 48 deflects, the clamping rod 410 at the bottom of the bracket 48 moves in the arc groove 49 on the seesaw 47, thereby adjusting the fulcrum of the seesaw 47. The clamping rod 410 on the seesaw 47 is in the position of the moving rod 46. When sideways, the seesaw 47 is driven by the rotating frame 45 to deflect so that the distance that the moving rod 46 moves up and down is minimized, so that the high corrugated paper surface can be processed. When the card rod 410 moves in the direction away from the moving rod 46, the moving distance of the moving rod 46 will be extended to press the corrugated papers with different flute heights, so that the pressing part 5 on the moving rod 46 can press the corrugated papers of different heights. According to the different heights of the corrugated papers, the pressing part 5 can accurately press the surface of the corrugated papers, which can avoid excessive pressure on the corrugated paper when pressed, causing the corrugated paper to deform during the drying process, thereby achieving adaptive pressing adjustment during the drying process of corrugated papers with different flute heights.

[0025] In this embodiment, the pressing member 5 includes a fixing frame 51 fixedly connected to the top of the moving rod 46, a slide rail 52 is provided on the fixing frame 51, a pressing frame 53 is slidably connected to the slide rail 52, a roller 54 is rotatably provided at the bottom of the pressing frame 53, and a vertically inclined inclined groove 55 is further provided on the side wall of the support frame 41, and a pulley 56 is provided on the pressing frame 53 extending into the inclined groove 55; The height of A flute is high, and the number of flutes per unit length is small. During the drying process, due to its structural characteristics, the difference in the evaporation rate of water on the upper and lower surfaces of the cardboard is relatively large, which is more likely to cause internal stress imbalance, thereby leading to the occurrence of curling. When the moving rod 46 moves downward, the pulley 56 on the pressing frame 53 will extend in the inclined groove 55 on the support frame 41. When the pulley 56 moves to the inclined groove 55, the pulley 56 will make the pressing frame 53 slide on the slide rail 52. For corrugated paper with low flute height, the pulley 56 moves vertically in the inclined groove 55. It is set straight downward and will not roll the corrugated paper. When rolling A-type corrugated paper, the moving distance of the moving rod 46 becomes shorter, and the pulley 56 is in the oblique side of the inclined groove 55. Then, when the moving rod 46 moves up and down, the pulley 56 slides in the inclined groove 55 and drives the pressing frame 53 to slide on the slide rail 52, so that the rolling roller 54 on the pressing frame 53 plays a rolling role when processing the surface of the corrugated paper, thereby avoiding the curling of the upper surface of the corrugated paper during the drying process.

[0026] The use method and advantages of the present invention: The use method of the drying device for corrugated box production, the working process is as follows: like Figures 1 to 9 As shown: S1: The push plate 23 drives the two connecting rods 27 to move the sliding frame 25 downward synchronously. When the sliding frame 25 moves downward, it drives the adjusting roller 26 to press the corrugated paper conveyed on the driving roller 28. The downward movement of the push plate 23 causes the adjusting roller 26 to contact the upper surface of the corrugated paper, and the thickness of the corrugated paper between the driving roller 28 and the adjusting roller 26 can be detected; S2: The steel belt 34 moves at the axis of the active sliding cone disk 313 and the active fixed cone disk 312, so that the steel belt 34 between the driving wheel 31 and the driven wheel 32 achieves low speed and high torque, which reduces the speed of the driven wheel 32. The speed of the driven wheel 32 is adjusted by the downward movement position of the sliding frame 25; S3: The driven gear 325 rotates to synchronize the rotation of the rotating gear 43. The rotating gear 43 drives the rotating disk 44 to move in a circular motion via the rotating rod 42. The rotating frame 45 intermittently pulls the rocker 47 to move. The pressing member 5 provided on the moving rod 46 can intermittently press the corrugated paper on the conveyor belt 11 during the drying process. S4: The adjustment rack 413 on the sliding frame 25 drives the rotating gear 412 to rotate. The rotation of the rotating gear 412 causes the screw 411 to rotate. When the screw 411 rotates, it drives the adjustment block 414 to slide on the support frame 41. The positioning rod 415 can drive the bracket 48 to deflect on the support frame 41. When the bracket 48 deflects, the clamping rod 410 at the bottom of the bracket 48 moves in the arc groove 49 on the rocker 47, thereby adjusting the fulcrum of the rocker 47. S5: When rolling A-corrugated paper, since the moving distance of the moving rod 46 becomes shorter, the pulley 56 is in the oblique side of the inclined groove 55. The pulley 56 slides in the inclined groove 55 and drives the pressing frame 53 to slide on the slide rail 52, so that the rolling roller 54 on the pressing frame 53 plays a rolling role when processing the surface of the corrugated paper.
