Description

Technical Field

[0001] This utility model relates to the field of packaging box assembly technology, specifically a rapid assembly and positioning device for packaging paper boxes. Background Technology

[0002] Packaging box assembly equipment is a powerful tool in the packaging industry, specifically designed for the efficient assembly of various packaging boxes. Integrating automation and intelligence, it can quickly grasp cardboard raw materials, precisely fold and glue them, and complete the assembly of various parts such as the box body and lid. The equipment can adapt to packaging boxes of various sizes and shapes, is easy to operate, and can switch production modes through parameter settings, significantly improving packaging efficiency and reducing labor costs. It is widely used in many industries such as food, electronics, and gifts, helping companies achieve efficient operation in the packaging process. However, existing packaging box assembly equipment still has some problems in use:

[0003] For example, the technical solution of the dual-station rapid assembly equipment for packaging boxes with application number 202121203469.7 is as follows: It includes a workbench, a raw material box on the top surface of the workbench, and a fixed column vertically arranged on one side of the raw material box. In this utility model, by setting up a workbench, raw material box, fixed column, crossbeam, threaded rod, forward and reverse motors, threaded sleeve, first cylinder, adsorption component, second cylinder, and baffle, during use, the first cylinder and adsorption component adsorb the packaging box raw material. Then, the forward and reverse motors drive the threaded rod to rotate, which in turn drives the threaded sleeve to move, thus assembling the packaging box. The packaging material is moved to the top of the groove. Under the action of the first cylinder and the suction component, the packaging material is placed inside the groove. Afterwards, the staff applies glue and performs assembly operations on the packaging material. However, the existing packaging box assembly device lacks precise positioning function. The cardboard is prone to shifting during the conveying and assembly process, which makes it impossible for the parts to fit precisely. Not only is the size deviation of the packaging box large and the scrap rate high, but a lot of manual secondary adjustment is also required, which is time-consuming and labor-intensive. In addition, the device is poorly designed in the cardboard folding stage and lacks a convenient folding auxiliary structure. It is difficult to fold cardboard of different materials and thicknesses.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was developed based on the existing packaging box assembly device. Utility Model Content

[0006] The purpose of this utility model is to provide a quick assembly and positioning device for packaging boxes, so as to solve the problems mentioned in the background art of lacking precise positioning function and inconvenience in folding packaging box materials.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A rapid assembly and positioning device for packaging cartons includes a bracket. A transport platform is provided on the top surface of the bracket. A rotating block is provided in the middle of the bracket, and sliders are provided on the left and right sides of the rotating block. Four positioning rods are provided at the front and rear positions on the left and right sides of the sliders, and the positioning rods form a clamping and positioning structure on the outside of the packaging carton substrate. Limiting plates are fixedly installed on the left and right sides of the lower front side of the bracket, and the bottom of each limiting plate is provided with a first sliding groove. A moving rod is slidably connected inside the first sliding groove, and a moving block is fixedly installed in the middle of the moving rod. Curved plates are provided on the outer sides of the left and right sides of the moving rod, and a pressing plate is provided at the front end of the curved plate.

[0009] Preferably, a servo motor is fixedly installed on the bottom surface inside the bracket, and a rotating rod is connected and installed above the output end of the servo motor, with a rotating block connected to the top of the rotating rod.

[0010] The above technical solution uses a servo motor on the bottom surface of the bracket and a connected rotating rod. The servo motor drives the rotating rod to rotate, providing power for the rotation of the rotating block. This allows the positioning rod to be adjusted in position, enabling clamping and positioning of packaging paper box substrates of different sizes and improving the versatility of the positioner.

[0011] Preferably, curved rods are hinged to both the left and right sides of the upper surface of the rotating block, and sliders are hinged to the other end of each curved rod. The sliders are slidably connected to the first sliding rod, and the first sliding rod is fixedly installed inside the bracket on both the left and right sides.

[0012] By adopting the above technical solution, the curved rod, slider and first slide rod are hinged on the rotating block. When the rotating block rotates, the curved rod drives the slider to slide on the first slide rod, thereby changing the position of the positioning rod, accurately clamping and positioning the packaging paper box substrate, and improving the positioning accuracy.

[0013] Preferably, the slider is hinged to a first connecting rod on both its front and rear sides, and a second connecting rod is hinged to the other end of each first connecting rod, and a positioning rod is fixedly connected above the outer end of the second connecting rod.

[0014] By adopting the above technical solution, the first link, the second link, and the positioning rod, which are hinged to the slider, allow the positioning rod to adaptively adjust its angle and position through the transmission of the first and second links when the slider moves, so as to better fit the shape of the packaging paper box substrate and enhance the stability of clamping and positioning.

[0015] Preferably, a first bevel gear is connected above the rotating rod, and a second bevel gear is meshed with the left side of the first bevel gear, and a transmission gear is fixedly connected to the left side of the second bevel gear.

[0016] By adopting the above technical solution, the first bevel gear, the second bevel gear, and the transmission gear connected to the rotating rod change the direction of power transmission through gear transmission, transmit the rotation of the rotating rod to the transmission gear, provide power for the movement of the moving block, realize the motion control of the pressing plate, and expand the function of the positioner.

[0017] Preferably, a rack is meshed above the transmission gear, a second slide rod is slidably connected to the rear side of the rack, and the front end of the rack is fixedly connected to the moving block.

[0018] Using the above technical solution, the transmission gear meshes with a spur rack, a second slide rod, and a moving block. The rotation of the transmission gear drives the spur rack to slide on the second slide rod, which in turn drives the moving block to move, thus precisely controlling the position of the pressing plate and facilitating the folding operation of the packaging paper box substrate.

[0019] Preferably, each of the curved plates is provided with a second sliding groove, and the moving rods pass through the second sliding grooves. The forward and backward movement of the moving blocks forms an up-and-down flipping structure for the pressing plate.

[0020] Using the above technical solution, the second slide groove of the curved plate, the moving rod and the pressing plate, when the moving block moves, the moving rod slides in the second slide groove, so that the pressing plate can be flipped up and down, which facilitates the folding of the packaging paper box substrate and improves assembly efficiency.
