Description

Technical Field

[0001] This utility model relates to the field of cardboard box packing machine technology, and in particular to a positioning mechanism for a cardboard box packing machine. Background Technology

[0002] Traditionally, cardboard box packing in the industry relies entirely on manual labor. Although manual packing offers good flexibility, the monotonous packing assembly line leads to an increasing error rate and extremely poor efficiency as working hours go by. Therefore, cardboard box packing machines have emerged to replace manual packing. However, traditional cardboard box packing machines still require human assistance. Due to the position and angle of the cardboard box within the machine, the packing machine cannot accurately position and pack it, leading to the development of positioning mechanisms in the packing machine industry.

[0003] Traditional carton packing machines rely on conveyor belts and guide rails to simply adjust the position of the cartons. During the conveying process, the guide rails straighten and position the cartons before they enter the packing area. However, this method of adjusting the position by guide rails is prone to inaccurate positioning, which can easily lead to packing failures and affect production efficiency. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a positioning mechanism for a carton packing machine, which aims to improve the problem of being unable to position and pack cartons.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning mechanism for a carton packing machine, comprising an operating table body, a positioning area roller rotatably connected to the upper surface of the operating table body, a packing area roller rotatably connected to the upper surface of the operating table body, a packing rope track rod fixedly connected to the top of the operating table body, a motor fixedly connected to the bottom of the operating table body, a notched gear fixedly connected to the output end of the motor, a rotating rod fixedly connected to the bottom of the notched gear, and a gripping positioning mechanism fixedly connected to the top of the operating table body;

[0006] The gripping and positioning mechanism includes two lead screw motors, vertical rods, and limiting wheels. The outer walls of the two lead screw motors are fixedly connected to the outer wall of the main body of the operating table. The output ends of the two lead screw motors are fixedly connected to the vertical rods. The tops of the two vertical rods are rotatably connected to rotating rods. One end of the inner wall of the rotating rod is rotatably connected to a fulcrum rod. The bottom of the vertical rod is slidably connected to a convex rail rod. The bottoms of the two vertical rods are fixedly connected to rotating shaft columns. The rotating shaft columns are fixedly connected to rotating shaft rods. The bottoms of the rotating shaft rods are fixedly connected to limiting wheels.

[0007] Furthermore, a fulcrum rod is fixedly connected to the top of the main body of the operating table.

[0008] Furthermore, a lifting plate is slidably connected inside the main body of the operating console.

[0009] Furthermore, a hydraulic rod is fixedly connected to the bottom of the lifting platform.

[0010] Furthermore, a grooved gear is fixedly connected to the bottom of the hydraulic rod.

[0011] Furthermore, the outer wall of the grooved gear meshes with the outer wall of the notched gear.

[0012] Furthermore, a tension spring is provided at the bottom of the vertical rod, and a rotating shaft is fixedly connected to the end of the tension spring.

[0013] Furthermore, a guide plate is fixedly connected to the outer wall of the packing rope track rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the carton is automatically moved to the middle by the positioning area rollers to achieve transportation. At this time, the positioning and clamping mechanism starts to work. Power is provided by two lead screw motors to retract the vertical rods at both ends to the middle. The power is balanced by the support rod connected by the rotating rod. There are two rotating shafts at the lower end of each vertical rod. The carton has two right-angle rotating shafts on the outer surface of the rotating shafts. There are limiting wheels at the lower end of the rotating shafts. The limiting wheels can lock the four corners of the carton. The internal rotating shafts are limited by tension springs, which can realize the return of the rotating shafts to their original position, adjust the angle of the carton, and realize the limitation of the carton position.

[0016] 2. In this utility model, when the carton moves to the upper end of the lifting plate, two packing rope rail rods extend two ropes to tie the carton. The carton rotates through the lifting plate to achieve vertical packing by rotating and changing its surface, thus achieving the effect of automatic flipping and rapid binding. This packing method is efficient and the procedure is simple. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-5 This utility model provides an embodiment of a positioning mechanism for a carton packing machine, comprising an operating table body 1, a positioning area roller 12 rotatably connected to the upper surface of the operating table body 1 for automatically conveying cartons, a packing area roller 18 rotatably connected to the upper surface of the operating table body 1 to replace the cartons conveyed by the positioning area roller 12, a packing rope track rod 2 fixedly connected to the top of the operating table body 1 for packing cartons, a motor 15 fixedly connected to the bottom of the operating table body 1, a notched gear 14 fixedly connected to the output end of the motor 15, a rotating rod 16 fixedly connected to the bottom of the notched gear 14, and a gripping positioning mechanism fixedly connected to the top of the operating table body 1; the gripping positioning mechanism includes two lead screw motors 4, a vertical rod 5, and a limiting wheel 11. The outer walls are all fixedly connected to the outer wall of the main body 1 of the operating table. The output ends of the two lead screw motors 4 are all fixedly connected to vertical rods 5. The vertical rods 5 can move. The top of the two vertical rods 5 are rotatably connected to rotating rods 6. One end of the inner wall of the rotating rod 6 is rotatably connected to a fulcrum rod 7. One end of the rotating rod 6 is connected to the vertical rod 5, and the other end is connected to the fulcrum rod 7, so that the two vertical rods 5 can be stably stressed. The bottom of the vertical rods 5 is slidably connected to a convex rail rod 8, which can make the vertical rods 5 slide in a direction. The bottom of the two vertical rods 5 is fixedly connected to a rotating shaft column 19. The rotating shaft column 19 is fixedly connected to a rotating shaft rod 10. The two rotating shaft rods 10 form a right angle, which can fix the four corners of the carton. The bottom of the rotating shaft rod 10 is fixedly connected to a limiting wheel 11. The limiting wheel 11 fits against the edge of the carton and limits the position of the carton.

[0026] Specifically, through the coordinated operation of the above structures, during use, the carton automatically moves to the center via the positioning rollers 12 to achieve transportation. At this time, the positioning and clamping mechanism starts to work, providing power through two lead screw motors 4 to retract the vertical rods 5 at both ends towards the center. The power is balanced by the support rod connected by the rotating rod 6. There are two rotating shafts at the lower end of each vertical rod 5. The carton has two right-angle rotating shafts 10 on the outer surface of the rotating shafts. The lower end of the rotating shaft 10 has a limiting wheel 11, which can lock the four corners of the carton. The internal rotating shaft 10 is limited by the tension spring 9, which can make the rotating shaft 10 return to its original position, adjust the angle of the carton, and limit the position of the carton.

[0027] Reference Figures 1-5 A fulcrum rod 7 is fixedly connected to the top of the main body 1 of the operating table. The fulcrum rod 7 can transmit power to the rotating rod 6. A lifting plate 17 is slidably connected inside the main body 1 of the operating table. The lifting plate 17 can lift the carton by the lifting force of the hydraulic rod 20. A hydraulic rod 20 is fixedly connected to the bottom of the lifting plate 17. A grooved gear 13 is fixedly connected to the bottom of the hydraulic rod 20. The outer wall of the grooved gear 13 meshes with the outer wall of the notched gear 14. The hydraulic rod 20 can lift the carton through the lifting plate 17. Then, the motor 15 rotates the output end of the notched gear 14, meshes with the grooved gear 13, and drives the upper carton to rotate and pack. A tension spring 9 is set at the bottom of the vertical rod 5. A rotating shaft rod 10 is fixedly connected to the end of the tension spring 9. When the limiting wheel 11 is in the limiting carton position, it will cause the rotating rod 6 to rotate and be misaligned. The tension spring 9 can limit the position of the rotating rod 6. A guide plate 3 is fixedly connected to the outer wall of the packing rope track rod 2. The packing rope is ejected in the packing rope track rod 2 and guided by the guide plate 3 to tie the carton.

[0028] Specifically, when the carton is moved to the lifting plate 17 at the center of the packing area rollers 18, the packing rope rails 2 on both sides tie two ropes to the surface of the carton. Then, the lifting plate 17 lifts and rotates the carton through the lower hydraulic rod 20 and the lower motor 15, and then ties two more vertical ropes to complete the packing of the carton. The carton is then transported out by the packing area rollers 18. When the carton moves to the upper end of the lifting plate 17, the two packing rope rails 2 extend two ropes to tie the carton. The carton rotates through the lifting plate 17 to achieve rotation and vertical packing, realizing the effect of automatic flipping and rapid binding. This packing method is efficient and the procedure is simple.

[0029] Working principle: When using this packaging and positioning mechanism, the cardboard is first placed on the upper part of the positioning area roller 12. The positioning area roller 12 will move the carton into the machine and slide it. When the carton enters the machine, the two lead screw motors 4 start working, clamping the vertical rods 5 at both ends of the machine inward along the convex rail rod 8. The rotating rods 6 at both ends are connected to the fulcrum rods 7 and rotate, so that the vertical rods 5 at both ends can be adjusted and balanced. There is a rotating shaft column 19 at the bottom of each vertical rod 5, which is connected to two right-angle rotating shaft rods 10. When the four corners of the carton are restrained by the limiting wheels below the rotating shaft rods 10, When the carton is locked at position 11, the tension spring 9 will be stretched to adjust the position of the carton, aligning the four corners of the carton and positioning it in the center. Then, the positioning roller 12 moves the carton to the rear end of the machine. When the carton is moved to the lifting plate 17 at the center of the packing roller 18, the packing rope track rods 2 on both sides will tie two ropes into the surface of the carton. Then, the lifting plate 17 will lift and rotate the carton through the lower hydraulic rod 20 and the lower motor 15, and tie two more vertical ropes to complete the packing of the carton. The carton will then be transported out through the packing roller 18.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
