Description
Technical Field
[0001] This invention relates to the field of glove manufacturing technology, and more specifically to an automatic box-opening device for glove production. Background Technology
[0002] In traditional processes, plastic gloves are a common household item with extensive applications in daily life and production, especially in the catering and medical fields, where they have broad application prospects.
[0003] In fully automated packaging lines for products such as gloves, the ability to automatically open and stably maintain folded, flattened cardboard boxes in a predetermined state is a crucial prerequisite for the smooth operation of subsequent high-speed boxing processes. As a product with diverse specifications and high consumption, the packaging efficiency of gloves directly impacts production costs and market supply.
[0004] Current box-opening devices, due to their focus on opening in a single mode, suffer from inconvenient mode switching, limited adaptability, and insufficient opening efficiency and forming stability when faced with diverse paper boxes of different sealing methods and sizes. This restricts the overall efficiency and changeover flexibility of the packaging line.
[0005] The information disclosed in this background section is intended only to enhance the understanding of the general background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0016] Preferably, the pressing Z-axis mechanism includes: a Z-axis pressing module, the output end of which is provided with a pressing frame, and the pressing frame is arranged parallel to the width adjustment Y-axis mechanism.
[0017] Preferably, the displacement counterweight mechanism includes: a counterweight frame, a counterweight block slidably mounted on the top of the counterweight frame via a guide rail, and two limiting wheels respectively provided at the Y-axis exit end of the pressing Z-axis mechanism and the displacement counterweight mechanism for limiting the paper box.

[0019] Preferably, the drive mechanism includes: a material handling motor, which is mounted on the output end of the three-way moving frame via a base, and the output shaft and rotating shaft of the material handling motor are respectively provided with pulleys, and a synchronous belt is provided between the two pulleys.
[0020] Preferably, the box-opening mechanism includes: a folding frame, two positioning suction cups disposed at the top of the folding frame, and a Y-axis seat slidably disposed at the top of the folding frame. A folding rod is installed between the two vertical pressure plates of the Y-axis seat. A cylinder is connected to the bottom end of the Y-axis seat through a plate. The output shaft of the cylinder is connected to the horizontal section shaft of the folding rod. The folding rod is U-shaped. The two vertical folding rod inflection points of the folding rod are respectively hinged to the Y-axis seat through shafts. Through the hinge point as the axis, the free end of the folding rod can rotate and fold the cardboard box. A driving structure is provided between the Y-axis seat and the folding frame.
[0021] Preferably, the drive structure includes: a driven rack fixedly mounted on the side wall of the folding frame; a servo motor is mounted on the side wall of the Y-axis seat via a mounting base; a drive gear is mounted on the output shaft of the servo motor; and the drive gear meshes with the driven rack.

[0023] The beneficial effects of this invention are as follows:
[0024] 1. By setting up multiple sets of inclined cardboard box hoppers including a width adjustment Y-axis mechanism, a pressing Z-axis mechanism, and a displacement counterweight mechanism, the inclined structure combined with pressing and width adjustment ensures the neatness and reliable pressing of the cardboard boxes. The unique displacement counterweight mechanism slides along the guide rail according to the number of boxes dispensed, and dynamically counterweights the cardboard boxes to achieve dynamic balance and stability of the cardboard boxes during the feeding process. This ensures a continuous and stable supply of cardboard boxes without stopping the machine, and greatly improves the reliability and production efficiency of the feeding system.
[0025] The resulting technical effects are: enabling the classified storage, adaptive adjustment, and stable and continuous supply of various sizes of paper boxes.
[0026] 2. By setting up a feeding assembly consisting of a three-way moving frame, a rotatable picking arm and a suction cup, the picking arm can rotate after adsorbing the paper box, automatically converting it from the tilted state of storage to the horizontal state required for opening the box. This simplifies the traditional picking, placing and flipping process that requires multiple independent mechanisms, saves space and time, and improves transfer efficiency and positioning accuracy.
[0027] The resulting technical effects are: precise grasping, efficient transfer, and intelligent posture transformation of cardboard boxes from the silo to the box opening station.
[0028] 3. By setting up an opening system that coordinates the mechanical folding mechanism and the vacuum pull mechanism, the mechanical folding mechanism can stabilize one side of the cardboard box by precisely connecting and rotating the U-shaped folding rod; at the same time, the vacuum pull mechanism adsorbs from the other side and, in coordination with multi-axis motion, smoothly pulls the box from a flat state into a cube in an "arc-shaped path". This coordinated mechanical action on both sides can adapt to cardboard boxes of different sizes and stiffness, ensuring that they are fully opened and stably maintained in a natural open state, providing perfect preparation for subsequent high-speed automatic boxing;
[0029] The resulting technical effect is that the entire process, driven by parameters, enables rapid switching of diverse paper boxes and fully automatic, highly stable pre-opening. Attached Figure Description

[0046] Example 1:
[0047] Reference Figures 1-8 The present invention discloses an automatic box-opening device for glove production, comprising:
[0048] To achieve categorized storage, adaptive adjustment, and stable supply of various sizes of cardboard boxes, this embodiment includes: a hopper support 1, which is equipped with multiple sets of cardboard box hoppers for storing different types of cardboard boxes. Each cardboard box hopper adopts an open, inclined structure and includes a width-adjusting Y-axis mechanism 2, inclinedly positioned within the hopper support 1, for adjusting the width of the cardboard boxes. The width-adjusting Y-axis mechanism 2 includes: a base plate; two sets of box clamping frames slidably arranged at the top of the base plate; a width-adjusting motor at the top of the base plate; a width-adjusting gear on the output shaft of the width-adjusting motor; and width-adjusting racks at the bottom of each of the two sets of box clamping frames, meshing with the width-adjusting gears. The material storage support 1 is equipped with a Z-axis pressing mechanism 3 for pressing the paper box from the Z direction. The Z-axis pressing mechanism 3 includes a Z-axis pressing module, and a pressing frame is provided at the output end of the Z-axis pressing module. The pressing frame is arranged parallel to the width adjustment Y-axis mechanism 2. The material storage support 1 is equipped with a displacement counterweight mechanism 4 for dynamically counterweighting the paper box from the Y direction to achieve dynamic balance and stability of the paper box during the feeding process. The displacement counterweight mechanism 4 includes a counterweight frame, and a counterweight block is slidably installed on the top of the counterweight frame via a guide rail. The Z-axis pressing mechanism 3 and the displacement counterweight mechanism 4 are respectively provided with two limit wheels 5 at the Y-direction paper box output ends for limiting the paper box.
[0049] To achieve precise gripping and posture transformation of cardboard boxes from the hopper to the opening station, in this embodiment: a feeding component is used to transfer cardboard boxes. The feeding component includes a three-way moving frame 11. A rotating shaft 12 is installed at the output end of the three-way moving frame 11. A picking arm 13 is provided at the shaft end of the rotating shaft 12 away from the output end of the three-way moving frame 11. A picking suction cup 14 is provided at the end of the picking arm 13 away from the rotating shaft 12. A driving mechanism is provided at the output end of the three-way moving frame 11 to drive the rotating shaft 12 to rotate. The driving mechanism includes a picking motor, which is installed at the output end of the three-way moving frame 11 via a base. The output shaft of the picking motor and the rotating shaft 12 are respectively provided with pulleys, and a synchronous belt is provided between the two pulleys.
[0050] To achieve pre-opening and folding of the cardboard box, in this embodiment: an opening mechanism for pre-opening the cardboard box includes: a folding frame 21, two positioning suction cups 22 disposed at the top of the folding frame 21, and a Y-axis seat 23 slidably disposed at the top of the folding frame 21. A folding rod 24 is installed between the two vertical pressure plates of the Y-axis seat 23. A cylinder 25 is connected to the bottom of the Y-axis seat 23 through a plate. The output shaft of the cylinder 25 is connected to the horizontal section shaft of the folding rod 24. The folding rod 24 is U-shaped. The two vertical folding rods of the anti-folding rod 24 are respectively hinged to the Y-axis seat 23 through the shaft. The free end of the folding rod can rotate and fold the cardboard box through the hinge point. A driving structure is provided between the Y-axis seat 23 and the anti-folding frame 21. The driving structure includes: a driven rack 26, which is fixedly set on the side wall of the anti-folding frame 21. A servo motor 27 is set on the side wall of the Y-axis seat 23 through the mounting seat. A drive gear 28 is set on the output shaft of the servo motor 27. The drive gear 28 is meshed with the driven rack 26.
[0051] To facilitate the opening and positioning of the lid on the other side of the cardboard box, in this embodiment: a box-opening reverse pull mechanism is used to assist in opening the box. The box-opening reverse pull mechanism includes: a reverse pull X-axis mechanism 31, a reverse pull Z-axis mechanism 32 is provided on the vertical side wall of the reverse pull X-axis mechanism, a reverse pull Y-axis mechanism 33 is provided at the top of the reverse pull Z-axis mechanism 32, and a reverse pull suction cup 34 is provided at the output end of the reverse pull Y-axis mechanism 33.
[0052] The working principle and usage process of this invention are as follows: First, during the feeding and unloading stage, multiple sets of inclined cardboard box hoppers are in standby mode. The width adjustment Y-axis mechanism 2 drives the width adjustment gear through its width adjustment motor. The width adjustment gear further drives the width adjustment rack, so that the two sets of box clamping frames are aligned and adjusted to a suitable width according to the current cardboard box specifications. The pressing Z-axis mechanism 3 presses down, pressing the entire stack of cardboard boxes in the hopper from above. When the system issues an unloading command, the feeding component is activated: the three-way moving frame 11 drives the entire unloading end to move to the target hopper's box outlet, and the unloading suction cup 14 picks up the bottom cardboard box. At the same time, the counterweight block of the displacement counterweight mechanism 4 slides along the guide rail according to the number of boxes unloaded, dynamically counterweighting the cardboard boxes to achieve dynamic balance and stability of the cardboard boxes during the feeding process. After the unloading suction cup 14 firmly picks up the cardboard box, the three-way moving frame 11 smoothly removes it from between the limiting wheels 5.
[0053] Next, during the transfer and unpacking preparation stage, the drive mechanism of the picking arm 13 is activated, which drives the picking arm 13 and the adsorbed cardboard box to rotate, changing it from an inclined state to a horizontal state, and then moving it to the top of the unpacking station. The two positioning suction cups 22 of the unpacking mechanism adsorb and position the cardboard box from below. Subsequently, the picking suction cup 14 releases the cardboard box.
[0054] Then, the core pre-opening and reverse folding stage begins. The box opening mechanism and the box opening reverse pull mechanism automatically adjust their motion trajectory and force according to the current specifications of the cardboard box. The main control system retrieves the current size data of the cardboard box and instructs the servo motor 27 of the box opening mechanism to start, driving the gear 28 to roll along the fixed driven rack 26, thereby precisely controlling the movement distance of the Y-axis seat 23 and the reverse folding rod 24 on it, so that the free end of the folding rod accurately abuts against the preset reverse folding position on the side of the cardboard box. At the same time, the box opening reverse pull mechanism performs coordinated positioning: the reverse pull X-axis mechanism 31 and the reverse pull Z-axis mechanism 32 are linked according to the same size data, so that the reverse pull suction cup 34 moves adaptively and adsorbs the corresponding optimal force point on the other side of the cardboard box; after positioning, the cylinder 25 of the box opening mechanism adjusts the output force according to the material and size of the cardboard box, smoothly pushing the free end of the folding rod 24, so that it rotates around the hinge point of the Y-axis seat 23, thereby smoothly and controllably folding the cardboard box upwards to one side. During this process, the anti-pull mechanism performs a crucial collaborative forming action: the anti-pull Z-axis mechanism 32 and the anti-pull Y-axis mechanism 33 work together according to a pre-programmed arc-shaped path that matches the height and width of the carton, guiding the upper part of the carton, which is firmly attached by the anti-pull suction cup 34, to move synchronously. This action is not a simple pull, but rather a precise combination of force and displacement that smoothly and geometrically transforms the carton from a flat state into a stable cubic open shape. Finally, when the free end of the folding rod 24 reaches the predetermined vertical upward posture, the carton has been fully and reliably opened and stabilized in a natural open state by the force balance between the mechanisms, without springback or deformation, thus preparing for the subsequent boxing process.
[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
