[0018] The width adjustment servo motor is mounted on the upper rotating disk above the moving disk via a mounting plate. The width adjustment servo motor is mounted on the top surface of the mounting plate. Two first guide rods are provided on both sides of the bottom surface of the mounting plate.

[0023] Furthermore, the box length adjustment mechanism includes a length adjustment servo motor, an adjustment screw, an upper core plate, a lower core plate, and a core shaft;

[0024] The lower turntable mechanism is fixedly installed on the lower core disk, and the core shaft is vertically installed on the top surface of the lower core disk. The upper core disk is movably fitted onto the outside of the core shaft, and the upper turntable mechanism is fixedly installed on the upper core disk.

The lower core disk is installed on the overload protector, and the conductive slip ring is installed above the upper core disk.

[0026] The advantages of this invention are:

[0027] The turntable mechanism of this invention adjusts the depth of the upper and lower box compartments respectively through the upper turntable box compartment height adjustment mechanism and the lower turntable box compartment height adjustment mechanism, adjusts the opening width of the upper and lower box compartments simultaneously through the upper and lower turntable box compartment width adjustment mechanism, and adjusts the distance between the upper and lower turntable mechanisms through the box compartment length adjustment mechanism. This achieves automatic adjustment of the height, width, and length of the paper box compartment, reduces labor costs, improves adjustment accuracy, shortens adjustment time, and improves production efficiency.

[0028] The upper turntable compartment height adjustment mechanism and the lower turntable compartment height adjustment mechanism of the present invention have the same structure. They both use a first height adjustment servo motor, a first gear ring, a first transition gear and a first rack to work together to drive each height adjustment plate to move synchronously, thereby realizing the synchronous adjustment of the depth of each compartment on the upper and lower turntable mechanisms. The adjustment speed is fast and the accuracy is high.

[0029] The first regulating gearbox in this invention consists of three sets of meshing gear structures, realizing three-level speed change and increasing the torque of the output gear.

[0030] In this invention, the upper and lower turntable gears of the upper and lower turntable compartment width adjustment mechanism are both mounted on an adjustment square steel and share the same width adjustment servo motor, which achieves the effect of adjusting the opening width of the upper and lower compartments simultaneously, while making the structure more compact.

[0031] In this invention, by installing matching electromagnets and magnetic plates on the upper and lower turntable mechanisms, the electromagnets attract the magnetic plates when energized, thus keeping the positions of the upper and lower moving discs constant and making the turntable mechanism more stable during operation.

[0032] In this invention, the box length adjustment mechanism is based on the lower turntable mechanism. Through the cooperation of the length adjustment servo motor, the adjustment screw, and the copper nut installed on the upper core plate, the upper core plate drives the upper turntable mechanism to move up and down, thereby adjusting the height of the upper turntable mechanism and thus achieving the effect of adjusting the distance between the upper and lower turntable mechanisms. In addition, second guide rods are installed in three directions of the mounting bracket. The second guide rods pass through the linear bearings of the upper core plate, which not only play a guiding role, but also better ensure the level and stability of the upper turntable mechanism.

[0033] In this invention, the rotary drive mechanism uses a cam divider to change the continuous rotation of the geared motor into a periodic, indirect rotation output from the power output shaft. The overload protector is located between the cam divider and the turntable mechanism body. In case of human error or turntable jamming, it can prevent the equipment from being overloaded and causing damage to the turntable parts and motor. In addition, by adding conductive slip rings, it avoids the situation of the wires of each servo motor getting tangled or broken. Attached Figure Description

A lower left reference plate 23 and a lower right plate 24 are respectively provided on both sides of the lower compartment slot of the lower moving plate 22. A lower height adjustment plate is provided between the lower left reference plate 23 and the lower right plate 24. The lower height adjustment plate is connected to the lower left reference plate 23 on both sides. The lower right plate 24 of the box compartment is slidably connected. The lower left reference plate 23 and the lower right plate 24 of the box compartment are both provided with second guide rails. The lower height adjustment plate of the box compartment has second guide rail grooves on both sides that match the second guide rails. The lower height adjustment plate of the box compartment is slidably connected to the second guide rails of the lower left reference plate 23 and the lower right plate 24 of the box compartment on both sides respectively. The lower limit block 25 of the box compartment is provided on the side of the lower slot of the moving plate 21 on the lower turntable opposite to the lower left reference plate 23 of the box compartment. The lower limit block 25, the lower height adjustment plate of the box compartment and the lower left reference plate 23 of the box compartment cooperate with each other to form the lower box compartment.

[0064] like Figure 8 As shown, the upper turntable compartment height adjustment mechanism 3 includes a first height adjustment servo motor 31, a first gear ring 32, and a first gear rack assembly corresponding to each compartment's upper height adjustment plate 15. The first height adjustment servo motor 31 and the first gear ring 32 are both mounted on the top surface of the upper turntable's moving plate 11. The first height adjustment servo motor 31 is meshed with the first gear ring 32 through a first adjustment gearbox 33. Figure 9 As shown, the first gear and rack assembly includes a first transition gear 34 and a first rack rod 35. The first transition gear 34 is mounted on the top surface of the upper rotating disk 11 and meshes with the first gear ring 32. One end of the first rack rod 35 is connected to the height adjustment plate 15 on the corresponding compartment, and the other end is movably mounted on the upper rotating disk 11 via a first rack rod limiting block 36 and meshes with the first transition gear 34. The first rack rod limiting block 36 is fixedly mounted on the top surface of the upper rotating disk 11 and cooperates with the upper rotating disk 11 to form a first rack guide groove. The first rack rod 35 is slidably connected in the first rack guide groove.

[0065] Among them, such as Figure 10-12 As shown, the first adjustable gearbox 33 includes a housing, an output shaft 331, an intermediate shaft 332, a first-stage gear 333, a second-stage gear 334, and a third-stage gear. Both the output shaft 331 and the intermediate shaft 332 are rotatably mounted in the housing. The first-stage gear 333 is rotatably mounted on the output shaft 331 via a bushing. The first-stage gear 333 includes an integrally formed first large wheel and a first small wheel. The input gear 311 of the first height adjustment servo motor 31 passes through the housing and meshes with the first large wheel. The second-stage gear 334 is fixedly mounted on the intermediate shaft 332. The second-stage gear 334 includes an integrally formed second large wheel and a second small wheel. The first small wheel meshes with the second large wheel. The third-stage gear is fixedly mounted on the output shaft 331. The third-stage gear includes an integrally formed third large wheel and a third small wheel. The third large wheel meshes with the second small wheel. The third small wheel extends out of the housing and serves as the output gear 335 of the first adjustable gearbox 33, meshing with the first gear ring 32. The first regulating gearbox 33 consists of three sets of meshing gears, achieving three-stage speed change and increasing the torque of the output gear.

[0066] The lower turntable compartment height adjustment mechanism 4 includes a second height adjustment servo motor, a second gear ring, and a second gear rack assembly corresponding to each compartment's lower height adjustment plate. To make the structure more compact, the second height adjustment servo motor is mounted above the upper turntable moving plate 11 via a mounting base. Two third guide rods are symmetrically arranged at the bottom of the mounting base. The upper turntable moving plate 11 has a third guide hole, and the third guide rods are movably inserted into the third guide hole. The bottom end of the third guide rod is connected to the lower turntable moving plate 22. The second height adjustment servo motor is meshed with the second gear ring via a second adjustment gearbox. Both the second gear ring and the second adjustment gearbox are mounted on the bottom surface of the lower turntable moving plate 22. The second gear rack assembly includes a second transition gear and a second rack rod. The second transition gear is mounted on the bottom surface of the lower turntable moving plate 22 and meshes with the second gear ring. One end of the second rack rod is connected to the corresponding compartment lower height adjustment plate, and the other end is movably mounted on the bottom surface of the lower turntable moving plate 22 via a second rack rod limiting block and meshes with the second transition gear. The structure of the second regulating gearbox is the same as that of the first regulating gearbox 33. The input gear of the second regulating gearbox passes downward through the upper moving plate 11 of the upper turntable and the lower moving plate 22 of the lower turntable in sequence, and then meshes with the first stage gear of the second regulating gearbox installed on the bottom surface of the lower moving plate 22. The output gear of the second regulating gearbox meshes with the second gear ring.

[0067] When adjusting the height of the cardboard box compartment, the first height adjustment servo motor 31 and the second height adjustment servo motor operate simultaneously to synchronously adjust the depth of the upper and lower box compartments. The first height adjustment servo motor 31 drives the first gear ring 32 to rotate through the first adjustment gearbox 33. The first gear ring 32 drives all the first transition gears 34 to rotate synchronously. The first transition gears 34 drive the first rack rod 35 to move linearly. The first rack rod 35 drives the upper height adjustment plate 15 of the box compartment to move back and forth, thereby completing the depth adjustment of the upper box compartment. The operating principle of the lower box compartment depth adjustment is the same as that of the upper box compartment.

[0068] like Figure 13-16As shown, the upper and lower turntable compartment width adjustment mechanism 5 includes a width adjustment servo motor 51, an adjustment square steel 52, an upper turntable gear 53, and a lower turntable gear 54. The width adjustment servo motor 51 is mounted above the upper movable disk 11 of the upper turntable via a mounting plate. The width adjustment servo motor 51 is mounted on the top surface of the mounting plate. Two first guide rods 55 are symmetrically arranged on both sides of the bottom surface of the mounting plate. The upper movable disk 11 of the upper turntable has first guide holes for the first guide rods 55 to pass through. The first guide rods 55 are movably inserted into the first guide holes, and the bottom ends of the first guide rods 55 are connected to the lower movable disk 22 of the lower turntable. The upper turntable gear 53 is rotatably mounted via bearings. On the bottom surface of the upper rotating disk 11, an upper rotating disk gear ring 56 is provided on the inner side of the lower rotating disk 12, and the upper rotating disk gear ring 56 meshes with the upper rotating disk gear 53; the lower rotating disk gear 54 is rotatably mounted on the top surface of the lower rotating disk 22 via bearings, and a lower rotating disk gear ring 57 is provided on the inner side of the upper rotating disk 21, and the lower rotating disk gear ring 57 meshes with the lower rotating disk gear 54; the upper rotating disk gear 53 has a square hole for the adjusting square steel 52 to pass through and move up and down, the adjusting square steel 52 is movably inserted into the square hole, the top end of the adjusting square steel 52 is connected to the output shaft of the width adjustment servo motor 51, and the bottom end of the adjusting square steel 52 is connected to the lower rotating disk gear 54.

[0069] The upper and lower turntable compartment width adjustment mechanism 5 also includes multiple electromagnetic positioning components, which are evenly distributed in all directions of the upper and lower turntable mechanisms, such as... Figure 17 As shown, the electromagnetic positioning assembly includes a matching magnetic suction plate 58 and an electromagnet 59 that generates magnetic force when energized. The electromagnet 59 is fixedly installed on the upper rotating plate 11 or the lower rotating plate 22, and the magnetic suction plate 58 is fixed on the upper rotating plate 12 or the lower rotating plate 21.

[0070] When the electromagnet 59 is energized, it attracts the magnetic plate 58, which can keep the upper and lower moving plates of the upper and lower turntable mechanisms in a fixed position and prevent them from changing. When the width of the cardboard box needs to be adjusted, the electromagnet 59 is de-energized and loses its magnetic force, allowing the upper turntable lower moving plate 12 and the lower turntable upper moving plate 21 to rotate independently. At this time, the width adjustment servo motor 51 drives the adjustment square steel 52 to rotate. The adjustment square steel 52 simultaneously drives the upper turntable gear 53 and the lower turntable gear 54 to rotate. The upper turntable gear 53 drives the upper turntable lower moving plate 12 through the upper turntable gear ring 56, and the lower turntable gear 54 drives the lower turntable upper moving plate 21 to rotate synchronously through the lower turntable gear ring 57. At the same time, the distance between the upper limit block 16 of the box and the upper left reference plate 13 of the box, and the lower limit block 25 of the box and the lower left reference plate 23 of the box are adjusted, thus simultaneously adjusting the opening width of the upper and lower box, completing the width adjustment of the cardboard box. After the adjustment is in place, the electromagnet 59 is energized and attracts the magnetic suction plate 58 below for fixation.

[0071] like Figure 18-22As shown, the box length adjustment mechanism 6 includes a length adjustment servo motor 61, an adjustment screw 62, an upper core disk 63, a lower core disk 64, and a core shaft 65. The lower rotating disk lower moving disk 22 of the lower rotating disk mechanism 2 is fixedly installed on the lower core disk 64, and the core shaft 65 is vertically installed on the top surface of the lower core disk 64. The upper core disk 63 has a shaft hole for the core shaft 65 to pass through. By movably inserting the core shaft 65 into the shaft hole, the upper core disk 63 can be movably fitted onto the outside of the core shaft 65. The upper rotating disk upper moving disk 11 of the upper rotating disk mechanism 1 is fixedly installed on the upper core disk 63. The length adjustment servo motor 61 is installed on the top of the core shaft 65 through a mounting bracket 67. The mounting bracket 67 is installed on the core shaft 65. At the top, a length adjustment servo motor 61 is mounted on the top surface of a mounting bracket 67. A second guide rod 66 is provided in each of the three directions of the mounting bracket 67. The upper core plate 63 has second guide holes that match each of the second guide rods 66. Each second guide rod 66 is mounted in its corresponding second guide hole via a linear bearing 68. The bottom end of each second guide rod 66 is fixedly connected to the lower core plate 64. A copper nut 69 matching an adjusting screw 62 is mounted on the upper core plate 63. The copper nut 69 has a threaded through hole matching the adjusting screw 62. The adjusting screw 62 is threaded into the threaded through hole of the copper nut 69. The top end of the adjusting screw 62 is connected to the output shaft 331 of the length adjustment servo motor 61. Conduits 610 are also provided on both sides of the core shaft 65 on the mounting bracket 67 for threading electrical wires.

[0072] When adjusting the length of the cardboard box compartment, the lower turntable mechanism 2 is used as a reference. The length adjustment servo motor 61 drives the adjustment screw 62 to rotate. The adjustment screw 62 pushes the copper nut 69 up and down through the thread. The copper nut drives the upper turntable mechanism 1 up and down through the upper core plate 63, adjusting the height of the upper turntable mechanism 1, thereby achieving the effect of adjusting the distance between the upper turntable mechanism 1 and the lower turntable mechanism 2. In addition, the mounting support 67 is equipped with a second guide rod 66 in three directions. The second guide rod 66 passes through the linear bearing 68 of the upper core plate 63, which not only plays a guiding role, but also better ensures the level and stability of the upper turntable mechanism 1.

[0073] like Figure 23-24As shown, the rotary drive mechanism 7 includes a geared motor 71, a cam divider 72, an overload protector 73, and a conductive slip ring 74. The geared motor 71 is connected to the power input shaft 721 of the cam divider 72 via a synchronous belt 75. The overload protector 73 is mounted on the power output shaft 722 of the cam divider 72, and the lower core disk 64 is mounted on the overload protector 73. An encoder 76 for monitoring the rotation status is mounted on the cam divider 72, and the conductive slip ring 74 is mounted above the upper core disk 63. The rotary drive mechanism 7 uses the cam divider 72 to change the continuous rotation of the geared motor 71 into periodic, indirect rotation output from the power output shaft 331. The overload protector 73 is located between the cam divider 72 and the turntable mechanism body. In case of human error or turntable jamming, it can prevent the equipment from being overloaded and damaged, resulting in damage to the turntable parts and motor. Furthermore, by adding the conductive slip ring 74, it avoids the tangling or breakage of the wires of the servo motors.

[0074] After the length, width and height of the cardboard box are adjusted, the power of the geared motor 71 is transmitted sequentially to the lower core plate 64 via the synchronous belt 75, the cam divider 72 and the overload protector 73. The lower core plate 64 drives the lower turntable mechanism 2 to rotate, and at the same time drives the upper core plate 63 to rotate via the core shaft and the second guide rod 66. The upper core plate 63 drives the upper turntable mechanism 1 to rotate, so that the entire turntable mechanism body is in an intermittent rotation state.

[0075] The turntable mechanism of this invention adjusts the depth of the upper and lower box compartments respectively through the upper turntable box compartment height adjustment mechanism 3 and the lower turntable box compartment height adjustment mechanism 4, adjusts the opening width of the upper and lower box compartments simultaneously through the upper and lower turntable box compartment width adjustment mechanism 5, and adjusts the distance between the upper turntable mechanism 1 and the lower turntable mechanism 2 through the box compartment length adjustment mechanism 6. This achieves automatic adjustment of the height, width and length of the paper box compartment, shortens the adjustment time, improves productivity, and is more accurate, precise and faster than manual adjustment. Moreover, the turntable mechanism body is designed in the shape of a disc, which is smaller in size and more conducive to transportation and layout. Various functional modules can be configured around the turntable mechanism body to realize multiple functions such as feeding, closing, coding, labeling and discharging, making the configuration more flexible.

[0076] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
