The position of the material sheet needs to be corrected in time to facilitate accurate positioning of the material sheet in the next process and ensure the processing quality of the packaging box. For thin material sheets, traditional corrective measures are performed manually, which has poor correction effects and low efficiency. Therefore, a device for preventing the material sheet of a roof-type packaging box from deviating is proposed to solve the above problem. Utility Model Content

[0011] The utility model has the following beneficial effects:

[0012] 1. The utility model provides a device for preventing the material plate of a roof-type packaging box from running off the track, comprising a conveyor belt and a side correction mechanism. The side correction mechanism comprises a bracket, a smooth strip, a lifting electric cylinder and a lifting platform. The lifting platform and the conveyor belt are arranged alternately and spaced apart, and the conveyor belt is installed in parallel on a frame; the smooth strip is symmetrically arranged above the conveyor belt; the bracket is located at the lower side of the conveyor belt, and the lifting platform is slidably connected to the bracket. The conveyor belt transports the material plate of the roof-type packaging box to the top of the lifting platform, and the lifting electric cylinder drives the lifting platform to move up, and the lifting platform drives the material plate to move up and leave the conveyor belt, and the smooth strip guides the left and right sides of the material plate to correct the posture of the material plate, and drives the lifting platform to descend so that the corrected material plate falls smoothly on the conveyor belt, thereby effectively correcting the thin material plate that has run off the conveyor belt.

[0013] 2. Set the conveyor belt on the lifting platform. The conveyor belt and the conveyor belt transport the material sheet in the same direction.

When the lifting platform drives the material plate to rise and fall, the upper surface of the material plate is constrained by the pressing plate to prevent the material plate from excessive warping during lifting and falling, which is conducive to uniform contact between the material plate and the conveyor belt and ensures the correction effect.

DETAILED DESCRIPTION

[0025] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments.

[0026] like Figure 1-4 As shown, the utility model provides a device for preventing material sheets of a roof-type packaging box from running off track, comprising a frame 1 and a conveyor belt 2, wherein a plurality of conveyor belts 2 are installed in parallel at left and right intervals on the top of the frame 1; the device also comprises a side correction mechanism 3, wherein the side correction mechanism 3 comprises a bracket 31, a smooth strip 32, a lifting electric cylinder 33, and a lifting platform parallel to the conveyor belt 2; the smooth strip 32 is symmetrically connected to the frame 1 above the conveyor belt 2; the smooth strip 32 is consistent with the transmission direction of the conveyor belt 2; the lifting platform is located between adjacent conveyor belts 2 and corresponds to the position of the smooth strip 32; preferably, the number of the lifting platforms is less than the number of the conveyor belts 2, and the left and right dimensions of the table surface formed by the plurality of lifting platforms are smaller than the left and right dimensions of the material sheet to avoid touching the lifting platforms during correction.

[0027] The lifting platform is connected to the bracket 31 by sliding up and down, and the bracket 31 is located at the lower side of the conveyor belt 2; the driving end of the lifting electric cylinder 33 pushes and pulls the lifting platform up and down. Preferably, the lifting platform and the smooth bar 32 are arranged in sequence along the conveying direction of the conveyor belt 2, and the smooth bar 32 partially overlaps with the lifting platform in the conveying direction of the conveyor belt 2; the length of the smooth bar 32 is greater than the length of the lifting platform, ensuring that the material plate and the smooth bar 32 have sufficient contact time.

[0028] When the conveyor belt 2 is conveying the sheet normally, there is a gap between the sheet and the lifting platform, that is, when the lifting cylinder 33 controls the lifting platform to descend to the lowest position, the support surface of the lifting platform is lower than the conveying surface of the conveyor belt 2. The lifting cylinder 33 is electrically connected to the controller, and the lifting cylinder 33 and the driving motor of the conveyor belt 2 are controlled by the controller to control the orderly movement of the sheet to complete the correction. The position of the sheet on the conveyor belt 2 is monitored by the electric eye; when it is detected that the sheet has completely moved above the lifting platform, the side correction mechanism 3 is started. When the side correction mechanism 3 is working, the driving motor can be controlled to stop so that the sheet on the conveyor belt stops moving; the sheets can also be placed on the conveyor belt in sequence at appropriate intervals. When the previous sheet is corrected, the next sheet slowly approaches the correction position, and the conveyor belt does not need to stop.

[0029] The lifting table is driven upward by the lifting electric cylinder 33, and the lifting table drives the material plate upward and away from the conveyor belt 2; at this time, the material plate moves horizontally on the lifting table for a distance due to inertia and then stops; during this distance of translation of the material plate, the left and right sides of the material plate contact the smooth strip 32, and the posture of the material plate is corrected under the guidance of the smooth strip 32. Finally, the lifting electric cylinder 33 drives the lifting table to descend and reset, driving the material plate to stably contact the conveyor belt 2, and the conveyor belt 2 transports the corrected material plate to the next processing step. Since the material plate is corrected after being lifted, the device can effectively correct the deviated thin material plate.

[0030] like Figure 3 As shown, a transfer belt 34 is provided on the lifting platform for transporting in the same direction as the conveyor belt 2, and the transfer surface of the transfer belt 34 is parallel to the conveyor surface of the conveyor belt 2. The number of transfer belts 34 is consistent with the number of lifting platforms, and multiple transfer belts 34 are driven by a drive motor, and the drive motor is electrically connected to the controller. Preferably, when the conveyor belt 2 is transporting normally, the transfer surface of the transfer belt 34 is flush with the conveyor surface of the conveyor belt 2; the transfer belt 34 and the conveyor belt 2 transport the material sheet synchronously. The lifting platform is driven by the lifting electric cylinder 33 to move up and down; at this time, the transfer belt 34 drags up the material sheet and transports the material sheet forward in the same direction; the smooth strip 32 corrects the material sheet moving on the transfer belt 34. Through the transfer belt 34, the material sheet can move a sufficient correction distance to ensure the correction effect, and the material sheet is always in motion, which reduces the time occupied by the anti-deviation correction and improves the transportation efficiency of the packaging box material sheet.

[0031] like Figure 3 ,4 As shown, the side correction mechanism 3 also includes a guide rod 35, an adjustment knob, and a spring; one end of the guide rod 35 is connected to the smooth bar 32, and the other end is threadedly connected to the adjustment knob; the adjustment knob abuts against the frame 1; the middle part of the guide rod 35 is slidably connected to the guide sleeve on the frame 1; the spring sleeve guide rod 35 is connected between the frame 1 and the smooth bar 32. The adjustment knob (not shown in the figure) abuts against the frame 1 by the elastic force of the spring; it can be understood that when the material plate touches the smooth bar 32, the smooth bar 32 can adaptively compress the spring and move back a certain distance to reduce the hard contact effect on the material plate, so that the correction process is smooth. By screwing the adjustment knob, the distance between the left and right smooth bars 32 can be adjusted to adapt to the correction of material plates of different sizes.

[0032] like Figure 3 As shown, the side correction mechanism 3 also includes a guide rod 35, a gear 36, a rack 37, a screw rod 38, and a nut 39; one end of the guide rod 35 is connected to the smooth bar 32, and the guide rod 35 is slidably connected to the guide sleeve on the frame 1 left and right; both ends of the screw rod 38 are connected to the frame 1 through support bearings, the screw rod 38 is meshed with the rack 37 through the gear 36, and the rack 37 is connected to the lifting platform through a connecting rod; the screw rod 38 is spirally connected to the nut 39, and the nut 39 is connected to the smooth bar 32.

[0033] The up and down movement of the lifting platform drives the screw rod 38 to rotate through the rack 37 and the gear 36, and drives the two smooth bars 32 to move closer or farther away through the nut 39; specifically, when the lifting platform moves downward to the lowest position, the two smooth bars 32 move away from each other; therefore, when the conveyor belt 2 is conveying normally, the two smooth bars 32 do not affect the movement of the material plate; when the lifting platform moves upward to the highest position, the two smooth bars 32 move closer; it can be understood that the minimum spacing between the two smooth bars 32 can be pre-adjusted according to the actual left and right dimensions of the material plate; the two smooth bars 32 push the side of the material plate for correction, and compared with the fixed position of the smooth bars 32, the moving and pushing action of the smooth bars 32 has a good correction effect and is more accurate in correction.

[0034] like Figure 5 , 6 As shown in Figures 7 and 8, the side correction mechanism 3 also includes a pressing plate 310 and a supporting plate 311 located above the lifting platform; the left and right dimensions of the pressing plate 310 are smaller than the left and right dimensions of the material plate to avoid contact during correction, and the lower surface of the pressing plate 310 is parallel to the conveyor belt 2; a sliding rod 312 is set on the upper surface of the pressing plate 310, and the supporting plate 311 is connected to the frame 1, and the supporting plate 311 is provided with a sliding sleeve in the up and down directions matching the sliding rod 312, and a stopper is set after the top end of the sliding rod 312 passes through the sliding sleeve.

[0035] Preferably, the lower surface of the pressing plate 310 is located above the conveyor belt 2. Under the action of gravity, the pressing plate 310 falls naturally, and the stopper is pressed down on the top of the sliding sleeve, so that a gap matching the thickness of the material plate is left between the lower surface of the pressing plate 310 and the conveyor belt 2; when the conveyor belt 2 conveys the material plate normally, the material plate passes through the gap between the pressing plate 310 and the conveyor belt 2; there is a gap between the material plate and the pressing plate 310; when the lifting platform drives the material plate to rise or fall upward or downward, the material plate contacts the pressing plate 310 and is clamped; at this time, the pressing plate 310 constrains the upper surface of the material plate, so that the movement of the material plate is smooth, which is conducive to uniform contact between the material plate and the conveyor belt 2, and ensures the correction effect.

[0036] like Figure 7 As shown, rollers 313 are provided on the lower surface of the pressing plate 310, and upwardly tilted guide edges are provided at the front and rear ends of the pressing plate 310. When the material sheet begins to enter under the pressing plate 310, the guide edges can prevent the material sheet from tilting up and hitting the pressing plate 310; after the material sheet contacts the lower surface of the pressing plate 310, the material sheet is translated by the conveyor belt 34 on the lifting platform, and the rollers 313 effectively reduce the friction force on the material sheet.
