DETAILED DESCRIPTION

[0027] The application will be further described in detail below with reference to the accompanying drawings.

[0028] The application discloses a carton conveying automatic calibration device. Figure 1 The application discloses a carton conveying automatic calibration device, which comprises a rack 1, a plurality of evenly distributed rollers 11 are arranged on the upper side of the rack 1, and all the rollers 11 are divided into two parts along the moving direction of the corrugated carton. A baffle 4 is arranged above the rack 1 and located between the two parts of the rollers 11. A lifting assembly 2 is arranged below the rack 1. A sensor for detecting the thickness of the carton on the rack 1 is further arranged on the rack 1, and the sensor is not shown in the figure. The sensor is electrically connected with the lifting assembly 2. The end of the baffle 4 close to the rack 1 is arranged as an inclined surface, and the inclined surface gradually inclines to the side where the rack 1 is located along the moving direction of the carton.

[0029] The corrugated carton is folded and flattened and placed on the rack 1. The sensor detects the thickness of the corrugated carton. Then, the lifting assembly 2 automatically adjusts the height of the rack 1, so that the distance between the rack 1 and the baffle 4 above for blocking the corrugated carton is suitable for the thickness of the single corrugated carton. Then, the rollers 11 rotate and drive the corrugated carton to move. In this way, by adjusting the height of the rack 1, the thickness of the corrugated carton is automatically adapted, and the corrugated carton can be conveyed in turn without stopping the conveying and manually adjusting.

[0030] The lifting assembly 2 comprises a base 21 arranged below the rack 1. A lead screw lifting machine 22 is further arranged below the positions of the four corners of the rack 1. The lead screw lifting machine 22 is installed on the corresponding base 21. A connecting plate 23 for lifting is rotatably connected with a screw rod of the lead screw lifting machine 22. The connecting plate 23 is fixedly connected with the rack 1. A worm gear reducer is further installed on the base 21. A driving motor 25 for driving the worm gear reducer is arranged on one side of the worm gear reducer. A transmission assembly 26 connected with the lead screw lifting machine 22 is further arranged on the worm gear reducer. The driving motor 25 is electrically connected with the sensor.

[0031] When the sensor detects the thickness of the corrugated carton, the driving motor 25 drives the worm gear reducer to operate, and drives the lead screw lifting machine 22 to elongate or contract through the transmission assembly 26, so as to control the height of the rack 1, thereby corresponding to the thickness of the corrugated carton.

[0032] The transmission assembly 26 comprises a steering gear 261 arranged on both sides of the worm gear reducer, and a driving shaft 262 is rotatably connected to the steering gear 261 opposite to the steering gear 261. The driving shaft 262 is connected with the steering gear 261 through a shaft coupling. A pair of driven shafts 263 are also rotatably connected to the steering gear 261. The driven shafts 263 are connected with the corresponding screw jacks 22. Thus, the driving motor 25 drives the four screw jacks 22 to lift through the worm gear reducer. That is, the worm gear reducer drives the steering gear 261 through the driving shaft 262, the steering gear 261 drives the driven shafts 263 to rotate, and the driven shafts 263 drive the screw jacks 22 to start, thereby driving the rack 1 to lift.

[0033] The base 21 is also fixedly connected with a support frame 3 arranged as a door-shaped frame. A horizontal rod 31 is fixedly connected to the support frame 3. A sliding block that moves horizontally is slidably connected to the horizontal rod 31. The baffle 4 is slidably connected to the sliding block in the vertical direction. A positioning bolt is arranged between the sliding block and the baffle 4. The positioning bolt is threadedly connected with the sliding block and abuts against the baffle 4. A adjusting screw 32 parallel to the horizontal rod 31 is rotatably connected to the support frame 3. The adjusting screw 32 penetrates through the sliding block and is threadedly connected with the sliding block.

[0034] The adjusting screw 32 is rotated to drive the sliding block to slide along the horizontal rod 31, thereby adjusting the position of the baffle 4. Then, the positioning bolt is screwed, and the baffle 4 can slide relative to the sliding block, thereby adjusting the baffle 4. For special cases, the baffle 4 can be adjusted to adapt to the thickness of the corrugated board.

[0035] A pair of limiting plates 5 are slidably connected to the horizontal rod 31. The adjusting screw 32 penetrates through the limiting plates 5 and is threadedly connected with the limiting plates 5. The sliding block is located between the two limiting plates 5. The adjusting screw 32 has opposite screwing directions at both ends, and the two limiting plates 5 are located at both ends of the adjusting screw 32, respectively. The adjusting screw 32 is rotated, and the pair of limiting plates 5 move towards each other. According to the width of the corrugated box, the distance between the pair of limiting plates 5 is determined, thereby arranging the corrugated boards in order.

[0036] Referring to Figure 1 and Figure 2 A wind channel 12 is installed below the rack 1. A plurality of through holes 13 are formed in the upper side of the rack 1 and communicate with the wind channel 12. Each through hole 13 is located between two adjacent rollers 11. Air is drawn in the wind channel 12. When the corrugated box covers above the through hole 13, the corrugated box is pressed on the rack 1 by the wind pressure, thereby making the corrugated box more stable when the rollers 11 drive the corrugated box to move and less likely to deviate.

[0037] The suction pipe is connected to the air duct 12, and the filter cloth bag 14 is arranged at the suction pipe. The pressing frame is arranged on the inner wall of the air duct 12, and the edge of the filter cloth bag 14 is pressed on the inner wall of the air duct 12. The pressing frame is fixed on the air duct 12 by the captive bolt. The dust and debris on the corrugated paper board enter the air duct 12 through the through hole 13, and are filtered and blocked by the filter cloth bag 14. When cleaning is needed, the captive bolt is unscrewed, the pressing frame is removed, and the filter cloth bag 14 is directly replaced, thereby reducing the possibility of dust and debris pollution.
