[0001] The invention belongs to the technical field of material transfer and relates to a station transfer device for paper box packaging. Background Art

[0002] Carton packaging refers to packaging boxes made of paper materials, which are mainly used to protect products, facilitate storage and transportation, and promote sales. In the process of packaging carton processing, station circulation processing is required, mainly transferring the carton from one station to another to perform different production tasks, such as printing, die-cutting, molding, boxing, etc., to ensure the smooth progress of the production process.

[0003] At present, in the process of circulation and transportation of cartons, it is usually necessary to use conveyor belts or conveyors for transfer. When using conveyor belts or conveyors for transfer, only linear transmission and transfer can be achieved. If the direction of transfer needs to be changed, it is difficult to use conveyor belts or conveyors. Only manual transfer can be used. The entire transfer equipment has a narrow scope of application and is inconvenient to use. Summary of the invention

[0006] Further description, the fixing mechanism includes a rotating block, a servo motor, a rotating rod and a clamping structure. A plurality of rotating blocks are rotatably connected to the turntable at even intervals along the circumferential direction. A servo motor is installed on the rotating block. The output shaft of the servo motor is connected to the turntable. When the servo motor is in operation, the output shaft is fixed, which causes the servo motor body to rotate, thereby driving the rotating block to rotate and adjusting the angle of the rotating block. A rotating rod is rotatably connected to the rotating block, and the rotating rod is provided with a clamping structure for clamping the paper box.

[0007] Further description, the clamping structure includes a U-shaped plate, a fixed cylinder and a clamping plate, the U-shaped plate is installed at the end of the rotating rod, the front and rear sides of the U-shaped plate are slidably connected with the clamping plates, the front and rear lower parts of the U-shaped plate are installed with fixed cylinders, the telescopic rod of the fixed cylinder is connected to the clamping plate, so that the telescopic rod of the fixed cylinder can drive the clamping plate to slide when it is extended and retracted, and the clamping plates on both sides are able to clamp the paper box when they are close to each other.

[0008] Further description, it also includes a reversing mechanism, which includes an electric push rod, a connecting rod, a bevel rack and a bevel gear. The electric push rod is installed on the lower front side and the upper rear side of the turntable. A connecting rod is installed on the body of the electric push rod. The connecting rod is connected to the bevel rack. The turning rod is connected to the bevel gear. The bevel rack is located at the moving trajectory of the bevel gear, so that the bevel gear will mesh with the bevel rack and be rotated by the bevel rack when moving.

[0009] Further description, it also includes a guiding mechanism, which includes a mounting rod, a guide plate, an adjusting screw and a sliding frame. The right side of the connecting seat is connected to two front and rear mounting rods, and the right sides of the two mounting rods are slidably connected to the sliding frames.

When the paper box is transported to the U-shaped plate by the conveyor belt, the paper box can be guided by the two guide plates, and the right side of the mounting rod is rotatably connected to an adjusting screw, and the adjusting screw is threadedly matched with the sliding frame so that the adjusting screw can drive the sliding frames on both sides to slide and adjust through the threads when rotating, and knobs are provided on the ends of the two adjusting screws away from each other to facilitate the rotation of the adjusting screws.

[0010] Further description, it also includes a locking mechanism, which includes a locking ring, a locking protrusion, a locking rod and an elastic member. The locking ring is connected to the rotating rod, and a plurality of locking protrusions are evenly spaced and connected to the locking ring. Two locking rods are slidably arranged on the rotating block, and the two locking rods are arranged opposite to each other.

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0028] A station flow equipment for carton packaging, such as Figure 1-Figure 4 As shown, it includes a base 1, a connecting base 2, a turntable 3, a stepper motor 4 and a fixing mechanism. The top of the base 1 is connected to the connecting base 2, and the turntable 3 is rotatably connected to the connecting base 2. A stepper motor 4 is installed in the middle of the upper part of the base 1. The output shaft of the stepper motor 4 is connected to the center of the turntable 3 so that the stepper motor 4 can drive the turntable 3 to rotate during operation. The turntable 3 is provided with a fixing mechanism for fixing the paper box.

[0029] like Figure 2-Figure 4 As shown, the fixing mechanism includes a rotating block 51, a servo motor 52, a rotating rod 53 and a clamping structure. A plurality of rotating blocks 51 are rotatably connected to the turntable 3 at uniform intervals along the circumferential direction. The servo motor 52 is installed on the rotating block 51. The output shaft of the servo motor 52 is connected to the turntable 3, so that when the servo motor 52 is in operation, the output shaft is fixed, which will cause the servo motor 52 body to rotate, thereby driving the rotating block 51 to rotate and adjusting the angle of the rotating block 51. The rotating block 51 is rotatably connected to the rotating rod 53, and the rotating rod 53 is provided with a clamping structure for clamping the paper box.

[0030] like Figure 2-Figure 4 As shown, the clamping structure includes a U-shaped plate 54, a fixed cylinder 55 and a clamping plate 56. The U-shaped plate 54 is installed at the end of the rotating rod 53. The clamping plates 56 are slidably connected to the front and rear sides of the U-shaped plate 54. The lower parts of the front and rear sides of the U-shaped plate 54 are installed with fixed cylinders 55. The telescopic rod of the fixed cylinder 55 is connected to the clamping plate 56, so that the telescopic rod of the fixed cylinder 55 can drive the clamping plate 56 to slide when it is extended and retracted. When the clamping plates 56 on both sides are close to each other, the paper box can be clamped.

[0031] When it is necessary to transfer workstations during the production process of carton packaging, this equipment can be used. When in use, this equipment is placed between two or more assembly lines in different directions, and the U-shaped plate 54 on the right is aligned with the assembly line for conveying carton. Then the assembly line will convey the carton to the U-shaped plate 54 on the right. At this time, the telescopic rods of the two fixed cylinders 55 at the U-shaped plate 54 are controlled to contract, driving the two clamping plates 56 to approach each other, thereby clamping the carton. After clamping, the stepper motor 4 can be controlled to drive the turntable 3 to rotate, thereby transmitting the carton through the U-shaped plate 54. When the next U-shaped plate 54 rotates to align with the assembly line for conveying carton, the new carton can be fixed according to the above operation. When the carton needs to be transported to other assembly lines, the carton can be located above the assembly line when the U-shaped plate 54 rotates to align with other assembly lines. At this time, the two fixed cylinders 55 can be controlled to rotate to align with the other assembly lines. The extension of the telescopic rod of the cylinder 55 drives the two clamping plates 56 to move away from each other, thereby loosening the carton and placing the carton on the assembly line. If the assembly line is located on the front and back sides of the device, the servo motor 52 can be controlled to operate. When the servo motor 52 is in operation, its output shaft is fixed on the turntable 3, and the output shaft of the servo motor 52 does not rotate, while the body of the servo motor 52 rotates. The rotation of the servo motor 52 body will drive the rotating block 51 to rotate, thereby driving the rotating rod 53 and the U-shaped plate 54 to flip. When flipping, the U-shaped plate 54 can flip forward or backward according to the direction of rotation of the servo motor 52, so as to place the carton on the U-shaped plate 54 at the front or rear side of the assembly line respectively, and then carry out the transportation of the carton. In this way, the present device can be used to circulate the carton during the process of carton packaging, and can be used to transfer the assembly lines in different directions during circulation, so as to have a wider range of applications.

[0032] like Figure 5 As shown, a reversing mechanism is also included, which includes an electric push rod 61, a connecting rod 62, a bevel rack 63 and a bevel gear 64. The electric push rod 61 is installed on the lower front part and the upper rear part of the turntable 3. A connecting rod 62 is installed on the body of the electric push rod 61. The connecting rod 62 is connected to the bevel rack 63. The rotating rod 53 is connected to the bevel gear 64. The bevel rack 63 is located at the moving track of the bevel gear 64, so that the bevel gear 64 will mesh with the bevel rack 63 when moving and be rotated by the bevel rack 63.

[0033] Initially, the telescopic rod of the electric push rod 61 is in an extended state. During the transportation process, if the direction of the carton needs to be changed, the two telescopic rods of the electric push rod 61 can be controlled to retract, driving the connecting rod 62 and the bevel rack 63 to move forward. After moving, the bevel rack 63 is located at the moving trajectory of the bevel gear 64, and then when the rotating rod 53 moves, it will drive the bevel gear 64 to move. After moving, the bevel gear 64 will move to mesh with the bevel rack 63 and be rotated by the bevel rack 63, thereby driving the rotating rod 53 to rotate. When the bevel gear 64 moves to disengage from the bevel rack 63, the rotating rod 53 just rotates one hundred and eighty degrees, thereby changing the surface of the carton. In this way, the direction of the carton during transportation can be changed, and when the bevel gear 64 rotates to mesh with the bevel rack 63 below, it can drive the rotating rod 53 to rotate and reset.

[0034] like Figure 6 and Figure 7 As shown, it also includes a guiding mechanism, which includes a mounting rod 71, a guide plate 72, an adjusting screw 73 and a sliding frame 74. The right side of the connecting seat 2 is connected to two front and rear mounting rods 71, and the right sides of the two mounting rods 71 ​​are slidably connected to sliding frames 74. The sliding frames 74 can slide back and forth along the mounting rods 71, and the sides of the two sliding frames 74 close to each other are connected to the guide plates 72. When the paper box is transported to the U-shaped plate 54 by the conveyor belt, the paper box can be guided by the two guide plates 72. The right side of the mounting rod 71 is rotatably connected to an adjusting screw 73, and the adjusting screw 73 is threadedly matched with the sliding frame 74 so that the adjusting screw 73 can drive the sliding frames 74 on both sides to slide and adjust through the threads when rotating. The ends of the two adjusting screws 73 that are away from each other are each provided with a knob to facilitate the rotation of the adjusting screws 73.

[0035] When the paper box passes through the assembly line and enters the U-shaped plate 54, it will first contact the two guide plates 72 and be guided into the U-shaped plate 54 by the two guide plates 72, thereby guiding the paper box. In the actual operation process, the distance between the two guide plates 72 can be adjusted according to the size of the paper box. When adjusting, it is only necessary to rotate the adjusting screw 73 to drive the two guide plates 72 to move closer to or away from each other through the thread, so as to adjust the distance between the guide plates 72.

[0036] like Figure 8As shown, it also includes a locking mechanism, which includes a locking ring 81, a locking protrusion 84, a locking rod 82 and an elastic member 83. The locking ring 81 is connected to the rotating rod 53, and a plurality of locking protrusions 84 are evenly spaced and connected to the locking ring 81. Two locking rods 82 are slidably arranged on the rotating block 51, and the two locking rods 82 are arranged opposite to each other. The locking rod 82 can be stuck at the two locking protrusions 84, so that the rotating rod 53 is limited by the cooperation of the locking rod 82, the locking protrusion 84 and the locking ring 81. An elastic member 83 is connected between the locking rod 82 and the rotating block 51, and the elastic member 83 is a connecting spring.

[0037] When the rotating rod 53 rotates, the locking ring 81 and the locking protrusion 84 will be driven to rotate. When the locking protrusion 84 rotates, it will repeatedly squeeze the locking rod 82 to move upward, and the elastic member 83 will be stretched. After the rotating rod 53 has completed its rotation, the locking rod 82 is reset and the locking protrusion 84 is clamped under the action of the elastic member 83, thereby limiting the locking ring 81 and the rotating rod 53 to prevent the rotating rod 53 from rotating at will.

[0038] like Fig. 9 and Fig.10 As shown, a height adjustment mechanism is also included, and the height adjustment mechanism includes a base 91 and a lifting cylinder 92. The base 91 is arranged on the four sides of the front, back, left and right below the base 1. A lifting cylinder 92 is installed in each base 91. The telescopic rod of the lifting cylinder 92 is connected to the bottom of the base 1. Controlling the extension and retraction of the telescopic rod of the lifting cylinder 92 can drive the base 1 to rise and fall, so as to adjust the height of the entire device.

[0039] When the height of the entire device needs to be adjusted, the lifting cylinder 92 can be controlled to move up and down to drive the base 1 to move up and down, thereby adjusting the height of the entire device to adapt to the use of assembly lines of different heights.

[0040] like Fig.11 As shown, a support frame 10 is also included, and the bottom of the two guide plates 72 are connected to the support frame 10. When the paper box moves between the two guide plates 72, if the U-shaped plate 54 has not rotated to align with the guide plate 72, the bottom of the paper box will be supported by the support frame 10, thereby supporting the paper box and preventing the paper box from falling.

[0041] It should be understood that the above description is only for exemplary purposes and is not meant to limit the present invention. Those skilled in the art will appreciate that variations of the present invention will be included within the scope of the claims herein.
