DETAILED DESCRIPTION

[0029] Please refer to Figures 1-10 In the embodiment of the application, the packaging box production stacking device comprises a conveying belt 1 and a workbench 2. The workbench 2 is arranged at one end of the conveying belt 1. A stacking groove is arranged at the center of the workbench 2. A placing plate 10 is arranged in the stacking groove. A sleeve 5 is arranged at the top of the workbench 2 along the center. The bottom end of the sleeve 5 is rotationally connected to the top of the workbench 2. A righting assembly 4 is fixedly arranged on the periphery of the sleeve 5. A fixing buckle 8 is fixedly arranged at the center of the top of the workbench 2 and away from the conveying belt 1. A connecting plate 9 is elastically and slidably arranged in the fixing buckle 8. A resisting plate 20 is fixedly arranged at the end of the connecting plate 9 close to the conveying belt 1. A transmission assembly is arranged in the side wall of the workbench 2. An auxiliary assembly is arranged at the top of the sleeve 5. When the fixing buckle 8 moves away from the conveying belt 1, the fixing buckle 8 drives the sleeve 5 to rotate through the transmission assembly.

[0030] ​Preferably, the bottom of the conveying belt 1 is provided with a lifting assembly, the lifting assembly comprises a pneumatic cylinder, a clamping jaw, the pneumatic cylinder is symmetrically arranged along the center of the bottom of the workbench 2, and is located opposite to the two sides of the conveying belt 1, the clamping jaw is fixedly installed on the telescopic output end of the pneumatic cylinder, and is used for clamping and positioning the placing plate 10; in use, the lifting assembly clamps and fixes the empty placing plate 10 through the cooperation of the pneumatic cylinder and the clamping jaw, and lifts the placing plate 10 into the stacking groove, so that the top of the placing plate 10 is flush with the top of the workbench 2, thereby facilitating the stacking work of the packaging boxes, and the top of the conveying belt 1 is flush with the top of the workbench 2, so that the packaging boxes are conveniently conveyed horizontally into the placing plate 10 on the workbench 2 for stacking work, and the sleeve 5 is arranged opposite to the two sides of the conveying belt 1 on the workbench 2; specifically, the lifting assembly and the conveying belt 1 are devices commonly used in the prior art for packaging box stacking work, and the detailed related structure and working principle will not be described here.

[0031] Please refer to Figures 1-10 Preferably, the righting assembly 4 comprises a righting plate 403; one end of the righting plate 403 is fixedly arranged on the periphery of the sleeve 5, and the bottom of the righting plate 403 is in sliding fit with the top of the workbench 2; the end of the righting plate 403 away from the sleeve 5 is elastically connected with a middle pipe 402, the end of the middle pipe 402 away from the righting plate 403 is elastically connected with a positioning pipe 401, and the end of the positioning pipe 401 away from the middle pipe 402 is fixedly provided with a semicircular block; the semicircular block is made of flexible material and has a smooth surface, so that when the packaging boxes deviate during placement or conveying on the conveying belt 1 and cannot enter the placing plate 10 horizontally, the righting assembly 4 can be rotated to right the deviated packaging boxes.

[0032] Specifically, in the initial state, the placing plate 10 is in the stacking groove under the action of the lifting assembly, the stop plate 20 is in the center position of the placing plate 10 under the elastic action between the fixed buckle 8 and the connecting plate 9, and the righting assembly 4 is in an elastic extension state; after the packaging boxes on the conveying belt 1 are conveyed to the placing plate 10, the end portion of the packaging boxes will contact the stop plate 20 and drive the stop plate 20 to move away from the conveying belt 1, thereby driving the sleeve 5 to rotate through the transmission assembly; at this time, the rotation directions of the two sets of sleeves 5 are opposite, and the righting assemblies 4 on the two sets of sleeves 5 are in opposite directions in the initial state; when the sleeve 5 rotates, the sleeve 5 drives the righting plate 403, the middle pipe 402 and the positioning pipe 401 to rotate, and then the semicircular block right the deviated packaging boxes, that is, rotates the packaging boxes to a state corresponding to each edge of the placing plate 10, thereby facilitating the stacking work; through the elastically arranged righting assembly 4, the righting assembly 4 can be automatically stretched or retracted to adapt to packaging boxes of different sizes.

[0033] Further, in order to improve the quality of the righting assembly 4 to the deflected packaging box, and avoid the packaging box from being deflected again after being righted by the righting assembly 4, preferably, the top of the workbench 2 is provided with a guide groove 12 along the center, the guide groove 12 is sleeved on the outer periphery of the sleeve pipe 5, and the bottom of one end of the middle pipe 402 close to the righting plate 403 is fixedly provided with a round rod which is in sliding fit with the guide groove 12. In actual use, the two guide grooves 12 are arranged in a mirror image symmetrical structure, and the guide groove 12 comprises an arc-shaped part and a rebound part which are connected end to end. When the round rod moves to a position close to the center of the side edge of the placing plate 10, that is, the round rod moves from the arc-shaped part to the rebound part, the round rod will quickly move to the sleeve pipe 5 under the elastic action between the righting plate 403 and the middle pipe 402, so as to make the middle pipe 402 shrink in the righting plate 403. That is to say, when the middle pipe 402 shrinks in the righting plate 403, the semicircular block is located at the center of the side edge of the placing plate 10. At this time, the deflected packaging box is forced to rotate to be righted by the two rotating righting assemblies 4. Therefore, the shrinkage of the middle pipe 402 in the righting plate 403 not only shortens the overall length of the righting assembly 4, but also separates the semicircular block from the side wall of the packaging box, avoiding the continuous contact and the continuous rotation of the packaging box caused by the continuous rotation of the righting assembly 4, and the secondary deflection of the packaging box, which affects the subsequent stacking operation. Through the lifting action of the arc-shaped part, the middle pipe 402 can change from the state of shrinking in the righting plate 403 to the state of stretching from the righting plate 403 to the outside, thereby improving the applicability to the packaging boxes with smaller sizes.

[0034] Please refer to Figures 1-5 , preferably, the auxiliary assembly comprises a top plate 6; the two ends of the top plate 6 are rotationally connected with the two sleeve pipes 5, and the center of the top plate 6 is provided with a gear 14, the two sides of the gear 14 are engaged with first toothed plates 13, and the opposite ends of the two first toothed plates 13 are fixedly provided with diagonal plates 7, the bottom of the diagonal plate 7 is in sliding fit with the top of the workbench 2, and the gear 14 is in transmission cooperation with the transmission assembly. In actual use, the two first toothed plates 13 are arranged along the diagonal line of the placing plate 10, and the length of the first toothed plate 13 is greater than the diagonal line length of the placing plate 10. When the packaging box is conveyed to the placing plate 10 or the deflected packaging box is righted by the righting assembly 4, the transmission assembly drives the gear 14 to rotate, thereby relatively moving the two first toothed plates 13, and then the diagonal plate 7 completes the centering and positioning of the packaging box, thereby facilitating the subsequent stacking of the packaging box. After completing the centering and positioning of a layer of packaging boxes, the placing plate 10 is driven to move downward by a distance of one packaging box by starting the lifting assembly, so that the subsequent packaging box can be directly conveyed to the packaging box placed on the placing plate 10.

[0035] Further, the transmission assembly comprises two groups of driving rollers 24; the driving rollers 24 are rotatably embedded in the side wall of the workbench 2, and the two groups of driving rollers 24 are respectively located below the two groups of sleeve pipes 5, the bottom end of the sleeve pipe 5 is provided with a limiting hole 25 in a circular array along the center, the side wall of the driving roller 24 is provided with a limiting shaft 26 which is slidably matched with the limiting hole 25, the first pull rope 23 is wound on the driving roller 24, the end of the first pull rope 23 away from the driving roller 24 is fixedly provided with a first pad, the side of the first pad away from the first pull rope 23 is provided with a second pad, the first pad and the second pad are fixedly provided with the elastic rope 21 therebetween, and the second pad and the bottom of the connecting plate 9 are fixedly provided with a second pull rope. In actual use, when the abutting plate 20 pushes the connecting plate 9 to move away from the conveying belt 1, the connecting plate 9 drives the sleeve pipe 5 to rotate through the cooperation of the second pull rope, the second pad, the elastic rope 21, the first pad, the driving roller 24, the limiting shaft 26 and the limiting hole 25.

[0036] In order to make the sleeve pipe 5 start to rotate only after the packaging box is completely conveyed from the conveying belt 1 to the placing plate 10, preferably, the bottom of the fixed buckle 8 is elastically connected with a limiting plate 19 in the side wall thereof, the end of the limiting plate 19 away from the fixed buckle 8 is slidably embedded in the side wall of the workbench 2, and the end of the limiting plate 19 away from the fixed buckle 8 is slidably matched with the first pad. In actual use, the end of the limiting plate 19 is provided with an inclined surface facing the second pad, in the initial state, the end of the abutting plate 20 away from the fixed buckle 8, the end of the limiting plate 19 close to the abutting plate 20 protrudes from the side wall of the fixed buckle 8 under the elastic action, the end of the limiting plate 19 is slidably matched with the first pad to limit the position of the first pad, and the limiting plate 19 is composed of two L-shaped plate pieces. When the packaging box is conveyed to the placing plate 10 by the conveying belt 1, the packaging box moves with the conveying and pushes the abutting plate 20 to move towards the fixed buckle 8, the abutting plate 20 pushes the connecting plate 9 to move and then pulls the second pull rope, drives the second pad to move, and the first pad cannot move due to being limited by the limiting plate 19, so that the elastic rope 21 is stretched under stress. When the abutting plate 20 moves to the end of the limiting plate 19 and pushes the limiting plate 19 to move towards the fixed buckle 8, the end of the limiting plate 19 is separated from the first pad by the movement of the limiting plate 19, and then the elastic rope 21 pulls the first pad and the first pull rope 23 to move towards the fixed buckle 8, and then drives the sleeve pipe 5 to rotate through the driving roller 24.

[0037] Please refer to Figures 7-8 , preferably, the driving roller 24 comprises a rotating ring and a wire roller; the wire roller is sleeved on the periphery of the rotating ring, the limiting shaft 26 is fixedly arranged on the rotating ring, the wire roller is matched with the rotating ring through a ratchet and pawl structure, and the first pull rope 23 is wound on the wire roller.

[0038] The side of the upper line roller of the driving roller 24 is rotationally provided with a buckle 27, the rotation connection position of the buckle 27 and the upper line roller of the driving roller 24 is provided with a coil spring, the buckle 27 is slidingly embedded in the side wall of the workbench 2, and through the cooperation of the coil spring and the ratchet pawl, the line roller and the rotating ring are driven to rotate through the cooperation of the ratchet pawl when the first cushion block moves to the fixed buckle 8, and when the abutting plate 20 and the first cushion block are no longer stressed, the line roller is reset to wind the first pull rope 23 through the action of the coil spring, thereby driving the abutting plate 20, the first cushion block and other structures to move and reset, avoiding the problem that the sleeve 5 is reversed when the first pull rope 23 is reset to wind, causing the conflict between the circular rod and the guide groove 12 and causing damage.

[0039] The sleeve 5 is sleeved with an inner shaft 502, the top end of the inner shaft 502 is peripherally fixedly provided with a rotating disc 501, the two groups of rotating discs 501 are transmissionally matched with the gear 14 through a belt, the bottom end of the inner shaft 502 slidingly passes through the center of the driving roller 24 and is fixedly provided with a base, a plurality of limiting holes 25 are also annularly arranged on the base, the top of the buckle 27 is provided with a second telescopic pipe 22, the side of the abutting plate 20 close to the conveying belt 1 is elastically provided with a pressing block 18 along the center, the abutting plate 20 is provided with a channel, the pressing block 18 is sealingly and slidingly connected with the channel, and the second telescopic pipe 22 and the channel are communicated through a connecting pipe.

[0040] It should be noted that the sizes of the sleeve 5 and the limiting holes 25 on the base are the same, the limiting shafts 26 on the driving roller 24 protrude from the upper and lower sides of the driving roller 24, the driving roller 24 can slide on the inner shaft 502, the base is rotationally embedded in the side wall of the workbench 2, and the rotating disc 501 is rotationally arranged in the side wall of the top plate 6

[0041] The top of the inner shaft 502 is annularly provided with a gear slot, the gear slot is meshingly matched with a trigger plate 11 on one side, the end of the trigger plate 11 away from the inner shaft 502 is slidingly connected with the side wall of the top plate 6, the bottom of the trigger plate 11 extends to the top of the workbench 2 and is slidingly attached to the top of the workbench 2, the end of the middle pipe 402 close to the sleeve 5 is fixedly provided with a sliding block 3 slidingly matched with the trigger plate 11, and the two groups of trigger plates 11 are arranged on the two sides of the inner shaft 502, so that when the trigger plate 11 moves away from the gear 14, the inner shaft 502 can be synchronously driven to rotate.

[0042] In actual use, in the initial state, the abutting plate 20 is separated from the end of the fixing buckle 8, one end of the limiting plate 19 protrudes from the end of the fixing buckle 8, and the end of the limiting plate 19 cooperates with the first pad, the two sets of righting assemblies 4 keep parallel state and face opposite directions, the bottom of the trigger plate 11 is located at the center of the sidewall of the placing plate 10 and is within the rotation track of the sliding block 3, the pressing block 18 protrudes from the sidewall of the abutting plate 20, and the second telescopic pipe 22 is in the contracted state, at this time, the limiting shaft 26 above the driving roller 24 extends into the limiting hole 25 of the sleeve 5, and the limiting shaft 26 below is separated from the limiting hole 25 of the base.

[0043] When the packaging box is conveyed to the placing plate 10, it is in the normal state, that is, one side of the packaging box is in contact with the abutting plate 20 and pushes the abutting plate 20 to move, at this time, the pressing block 18 is pushed into the channel, thereby extruding the gas in the channel into the second telescopic pipe 22 through the connecting pipe, so that the second telescopic pipe 22 collides and pushes the buckle 27 to move downward, so that the upper half of the limiting shaft 26 is separated from the limiting hole 25 on the sleeve 5, and the lower half of the limiting shaft 26 moves into the limiting hole 25 on the base, then the abutting plate 20 moves and pushes the connecting plate 9 to move, thereby pulling the second pull rope through the cooperation of the second pad, the elastic rope 21 and the limiting plate 19, so that the elastic rope 21 is stretched, then when the abutting plate 20 pushes the limiting plate 19, the limiting plate 19 is separated from the first pad, then the elastic rope 21 pulls the first pad to move towards the fixing buckle 8, through the cooperation of the first pull rope 23, the driving roller 24, the limiting shaft 26 and the limiting hole 25, the base is rotated, thereby the inner shaft 502 is rotated, the inner shaft 502 is rotated to drive the gear 14 to rotate, thereby the two sets of first toothed plates 13 are close to each other to complete the centering and clamping of the packaging box through the diagonal plate 7.

[0044] In the initial state, if the packaging box transported to the placing plate 10 is deflected at an angle, the packaging box cannot contact the two groups of pressing blocks 18 at the same time and push the pressing blocks 18 to move towards the abutting plate 20 to shrink, so at this time the packaging box only pushes the abutting plate 20 to move towards the fixed buckle 8, and the buckle 27 does not move downwards, and at this time the upper half of the limiting shaft 26 cooperates with the limiting hole 25 on the sleeve 5, and when the abutting plate 20 cooperates with the limiting plate 19, the driving roller 24 rotates to drive the sleeve 5 to rotate, and at this time the rotation directions of the two groups of sleeves 5 are opposite, so the deflected packaging box is rotated and righted through the cooperation of the righting assembly 4 and the guide groove 12, when the righting assembly 4 moves to the center position on one side of the placing plate 10, the middle tube 402 is retracted into the righting plate 403 under the elastic action between the middle tube 402 and the righting plate 403, and in this process, the sliding block 3 rotates to the side close to the placing plate 10 of the trigger plate 11, so when the sliding block 3 moves with the middle tube 402, the sliding block 3 drives the trigger plate 11 to move towards the sleeve 5, and then the trigger plate 11 drives the inner shaft 502 to rotate, and then the rotating disc 501 drives the gear 14 to rotate, so that the first toothed plate 13 completes the centering and clamping of the packaging box through the diagonal plate 7.
