DETAILED DESCRIPTION

[0022] like Figure 1-Figure 3, a carton production line, comprising a box gluing machine 1, a watermark machine 2, a transfer platform 3, a bracket 4 and a conveyor belt device 5 installed on the top of the bracket 4, the conveyor belt device 5 and the bracket 4 form an assembly and the transfer platform 3 is located between the box gluing machine 1 and the watermark machine 2, a composite top plate 6 is provided on the top of the bracket 4, and a support plate 7 is fixed between the bottom of the composite top plate 6 and the top of the bracket 4, a displacement sensor is installed on the top of the support plate 7, the side edges of the composite top plate 6 are all fitted with clamping plates 8 through pins, and one end of the pin is equipped with a first gear 9, a gear rack output device 10 is installed on the top of the composite top plate 6, four output structures are provided in the gear rack output device 10 and are respectively engaged with the first gears 9 provided on the sides of the composite top plate 6, so that the two clamping plates 8 in relative positions can be rotated in the internal space of the composite top plate 6 for clamping or giving way; The gear plate output device 10 includes two second gears 101, and the middle parts of the two second gears 101 are both equipped with bearings with support shafts fixed on the top of the composite top plate 6. The combined use of the support shaft and the bearing ensures that the self-rotation operation can ensure its own continuous rotation stability, providing a stable and continuous transmission effect for the subsequent associated transmission structure. The surface of the second gear 101 is respectively meshed with the first composite spur plate 102 and the second composite spur plate 103, and the structural angle between the first composite spur plate 102 and the second composite spur plate 103 is set to ninety degrees and a clearance space is set, thereby ensuring that the first composite spur plate 102 and the second composite spur plate 103 are smoothly meshed and transmitted while avoiding The probability of structural interference generated by the linkage operation of the first compound spur plate 102 and the second compound spur plate 103 is reduced. The two first compound spur plates 102 and the two second compound spur plates 103 are respectively arranged in parallel with the four sides of the compound top plate 6, providing structural conditions for subsequent one-to-one meshing transmission, and one end of the two first compound spur plates 102 and one end of the two second compound spur plates 103 serve as the output structure of the gear plate output device 10, which can be meshed with the first gear 9 arranged on the corresponding side of the compound top plate 6 for transmission. In the face of multiple transmission structures, the use effect of synchronous meshing transmission can be provided, thereby ensuring the subsequent synchronous multi-directional relative clamping and centering effect of the stacked cardboard blanks 19 carried in the compound top plate 6; A synchronous wheel is installed on the top of the support shaft of the middle set of the second gear 101, and a synchronous belt 105 is installed between the two synchronous wheels in relative positions, thereby providing a power source and the transmission conditions of the two output structures. Then, from the perspective of the device structure setting, the number of structures of the device is reduced, the weight of the device is reduced, and the technical effect of reducing the use cost is achieved. One end of one of the synchronous wheels is connected to the first brake servo motor 104 installed on the top of the composite top plate 6. The first brake servo motor 104 is used as a power source to provide automated power for subsequent multiple associated meshing transmission structures. The bottom of the first composite spur plate 102 and the bottom of the second composite spur plate 103 are both clamped with a slide rail 106 fixed to the top of the composite top plate 6. The slide rail 106 is used as an auxiliary support. In addition to ensuring the reciprocating and stable movement of the first composite spur plate 102 or the second composite spur plate 103, the first composite spur plate 102 and the second composite spur plate 103 are protected from movement correction to maintain the transmission effect for subsequent long-term use.

[0023] During use, for the multiple cardboard blanks 19 processed by the watermark machine 2 and collected as a transition on the transfer platform 3, the multiple cardboard blanks 19 are stacked in sequence and placed on the top of the conveyor belt device 5 for transportation. After the multiple stacked cardboard blanks 19 are aligned with the composite top plate 6 under the automatic transportation of the conveyor belt device 5, the displacement sensor on the support plate 7 synchronously detects and the existing control system is linked to start the first brake servo motor 104, so that the output end of the first brake servo motor 104 drives the corresponding first composite spur plate 102 to rotate synchronously. At the same time, under the synchronous transmission of the synchronous belt 105 and the corresponding two synchronous wheels, the other first composite spur plate 102 will rotate synchronously. The two rotating first compound spur-tooth plates 102 will respectively mesh with and drive the corresponding second compound spur-tooth plates 103 and the first compound spur-tooth plates 102 to perform linear displacement. At the same time, one end of the second compound spur-tooth plate 103 and one end of the first compound spur-tooth plate 102 will synchronously mesh with and drive the corresponding first gears 9, ultimately making the four clamping plates 8 face each other in pairs and all face the inner space of the compound top plate 6 for clamping and centering adjustment, thereby synchronously clamping and centering the multiple cardboard blanks 19 in a stacked state, providing favorable conditions for the quality of subsequent transportation to the box gluer 1 for further processing; After the clamping and centering is completed, the first brake servo motor 104 outputs in the reverse direction to reset the four clamping plates 8 to the initial state horizontal with the gluer 1, and then continues to be transported to the existing loading structure of the gluer 1 through the conveyor belt device 5 to continue the next process.

[0024] like Figure 2The clamping plate 8 includes a main clamping plate body 81, and the side structures around the composite top plate 6 are provided with a clearance groove that can be movably connected to the main clamping plate body 81. The end of the pin shaft is movably connected to the inner wall of the clearance groove, thereby ensuring that the subsequent main clamping plate body 81 and other structures provided on the main clamping plate body 81 can rotate stably, and the middle part of the pin shaft is fixedly connected to the top of the main clamping plate body 81, and the surfaces of both ends of the main clamping plate body 81 are installed with a first clamping plate 82 perpendicular to itself.

[0025] When in use, the displacement of the clamping plate 8 will be clamped horizontally and centered by the two first clamping plates 82 set at its two ends, avoiding the problem of local tilting that occurs in single-line clamping and optimizing the effect of centering and clamping.

[0026] like Figure 3-Figure 4 The first splint 82 is provided with a semi-open groove in the side thereof, and a buffer assembly 85 is provided in the semi-open groove, and the buffer assembly 85 includes a support sleeve 851, and the support sleeve 851 is fixed to the outer surface of the side of the first splint 82, and a linkage rod 852 is clamped in the middle of the support sleeve 851, and the outer side of one end of the linkage rod 852 is provided with a first spring 853 installed between the surface of the support sleeve 851 and the end surface of one end of the linkage rod 852, and the other end of the linkage rod 852 is provided with an annular structure and a buffer shaft 854 is provided through a bearing. When the first spring 853 is not under force, part of the structure of the outer ring of the buffer shaft 854 passes through the semi-open groove and faces the internal space of the composite top plate 6, and the linkage rod 852 adopts a T-shaped structure to avoid the phenomenon of structural detachment during the reciprocating movement of the structure, thereby ensuring the reliability of the clamping plate 8 during subsequent continuous use.

[0027] During use, when the two opposing clamping plates 8 are clamping and centering the multiple stacked cardboard blanks 19 that have arrived inside the composite top plate 6, the buffer shaft 854 inside the buffer assembly 85 first contacts the corresponding side edge of the cardboard blank 19, and during the further relative movement and clamping process of the first clamping plate 82, the buffer shaft 854 will retract into the semi-open groove to make way under the guidance of the linkage rod 852 and the support sleeve 851 and the elastic traction of the first spring 853, thereby achieving a buffering effect of making way in the initial stage of clamping and centering, avoiding direct hard clamping and centering to damage the cardboard blank 19, and reducing the defective rate in the overall process.

[0028] like Figure 6-Figure 7, a second support plate 83 perpendicular to the main clamping plate 81 is sleeved in the middle of the first support plate 82, further expanding the area of ​​direct contact clamping, an installation space is opened in the second support plate 83, providing installation and making way conditions for subsequent related structures, and a slide groove 84 communicating with the installation is opened in the side wall structure of the second support plate 83 facing the inside of the composite top plate 6, further making way, a screw transmission mechanism is provided in the installation space, and the output structure of the screw transmission mechanism is connected to a pressure detection device 17 that can be movably connected to the slide groove 84, thereby using the screw transmission mechanism to drive the pressure detection device 17 to perform side alignment detection on multiple cardboard blanks 19 clamped in the center, providing a technical means to further improve processing quality; The screw transmission mechanism includes a second brake servo motor 11, a screw 12, and a linkage plate 16. The end of the screw 12 is equipped with a bearing seat installed on the inner wall of the second support splint 83 through a bearing sleeve, providing stable support for the subsequent continuous rotation transmission of the screw 12 itself, and the end of one end of the screw 12 is transmission-connected to the fourth gear 13, and the output end of the second brake servo motor 11 is transmission-connected to the fifth gear 14 meshing with the fourth gear 13. The screw 12 is connected to the second brake servo motor 11 as a power source through staggered meshing, thereby meeting the transmission requirements of the screw 12 while also being adaptable to installation in a small space. A support seat is installed between the housing surface of the second brake servo motor 11 and the inner wall of the second support splint 83 to ensure the stability of the second brake servo motor 11 during output. The pressure detection device 17 includes a support sleeve 171, a cross-shaped rod 172 and a pressure sensor 174. One end of the cross-shaped rod 172 and the pressure sensor 174 are both sleeved inside the support sleeve 171 and in contact with each other. The linkage plate 16 is installed between the surface of the support sleeve 171 and the surface of the nut 15 as the output structure of the screw transmission mechanism, so that the pressure detection device 17 and the nut 15 can operate smoothly in linkage. The interior of the support sleeve 171 is sleeved with a second spring 173, and the two ends of the second spring 173 are respectively fixed to the inner wall of the support sleeve 171 and the cross-shaped rod 172. On the surface of one end, the cross-shaped rod 172 can move back and forth and reset. The other end of the cross-shaped rod 172 is transmission-connected to a support ring frame 175. The side structure of the support ring frame 175 facing the inside of the composite top plate 6 is set as a round rod structure, and a roller 176 is movably sleeved on the outside of the round rod structure, and the outer ring corner structure of the roller 176 is engaged with and protrudes from the slide groove 84, thereby meeting the operational requirements of the roller 176 for rotating and compressive transmission, and also utilizing the engagement of the roller 176 with the slide groove 84 to provide limited support for the reciprocating lifting and lowering displacement of the nut 15 and the pressure detection device 17, thereby preventing the nut 15 from rotating synchronously with the screw 12.

[0029] During use, after a plurality of stacked cardboard blanks 19 are clamped and aligned, the second brake servo motor 11 is started, and the output end of the second brake servo motor 11 drives the fifth gear 14 to rotate synchronously, and then the fifth gear 14 is engaged with the fourth gear 13, so that the fourth gear 13 drives the lead screw 12 to rotate synchronously, and the rotated lead screw 12 will engage the transmission nut 15, so that the nut 15 drives the pressure detection device 17 to perform synchronous lifting and lowering displacement in the slide groove 84 through the linkage plate 16, and the roller 176 inside the pressure detection device 17 will contact the corresponding side structures of the plurality of cardboard blanks 19 in a friction rolling manner; If the multiple cardboard blanks 19 are well clamped and aligned, the force applied to the roller 176 during rolling should be relatively balanced. Therefore, the multiple pressure data values ​​generated by the roller 176 exerting pressure on the pressure sensor 174 through the support ring 175 and the cross-shaped rod 172 are not much different. If, after the multiple cardboard blanks 19 are clamped and aligned, some of the cardboard blanks 19 still protrude from the sides or some of the cardboard blanks 19 are not large enough to be buried between two adjacent cardboard blanks 19, resulting in a gap, the nut 15 drives the pressure detection device 17 to perform synchronous lifting and displacement in the slide 84 through the linkage plate 16. During this process, the roller 176 inside the pressure detection device 17 applies pressure to the pressure sensor 174 through the support ring frame 175 and the cross-shaped rod 172, and a pressure data value with a sudden change in value will be generated among the multiple pressure data. At this point, the second brake servo is controlled. The servo motor 11 and the related structure reciprocating transmission nut 15, linkage plate 16 and pressure detection device 17 and synchronously observe the changes in the pressure data value, which can quickly find the protruding or sunken cardboard blank 19. At this time, the two clamping plates 8 can be flipped and reset through the reset transmission of a first composite straight tooth plate 102, and then make way for part of the space of the composite top plate 6. Then, one hand pushes, using the remaining two clamping plates 8 that are still in the clamping state as limit supports, and the other hand pulls the protruding or sunken cardboard blank 19 out of the multiple cardboard blanks 19.

[0030] like Figure 6 A constant pressure platform 18 is installed on the inner wall of the top of the second clamping plate 83, and the pressure detection device 17 can be in pressure contact with the outer surface of the constant pressure platform 18 under the transmission of the screw transmission mechanism.

[0031] During use, taking into account the reliability of the pressure detection device 17 during continuous use, a constant pressure platform 18 is set as the zero detection position. Subsequently, after a use cycle of the pressure detection device 17 is completed, the second brake servo motor 11 is started, and the output end of the second brake servo motor 11 drives the fifth gear 14 to rotate synchronously, and then the fifth gear 14 is used to engage the fourth gear 13, so that the fourth gear 13 drives the lead screw 12 to rotate synchronously, and the rotated lead screw 12 will engage the transmission nut 15, so that the nut 15 drives the pressure detection device 17 to move up and press the constant pressure platform 18 through the linkage plate 16, and then, the roller 176 applies pressure to the pressure sensor 174 through the support ring frame 175 and the cross rod 172, records the pressure data and in the subsequent continuous operation process, it reciprocates, continuously records multiple sets of pressure data and draws a graph surface. When the pressure data continues to decrease, it indicates that the reset ability of the second spring 173 is decreasing. When it exceeds the preset value, the pressure detection device 17 should be replaced or repaired.
