Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a packaging box opening device. Background Technology

[0002] In the canned food production and packaging industry, the processes of opening packaging boxes and loading cans directly impact production efficiency and product quality. Currently, the industry's packaging methods have significant shortcomings, hindering improvements in production efficiency.

[0003] Manual packaging remains the primary production method for some small and medium-sized enterprises. Manually opening and loading boxes is time-consuming and susceptible to fatigue and skill level issues, resulting in significant errors in the opening angle of the boxes. This leads to cans being placed crookedly, and in automated conveying processes, the cans are prone to tipping over and breaking due to instability, significantly increasing rework costs and material losses.

[0004] Many automated packaging box opening devices use single-axis robotic arms or pneumatic push rods to open the boxes. While these devices can open the boxes, they cannot be integrated with subsequent can loading and transfer processes. Significant spacing needs to be maintained between these devices, requiring additional manual transition stations. This necessitates multiple workers per shift to coordinate processes, and the overall equipment occupies a large area, increasing the company's site rental costs. Utility Model Content

[0005] The purpose of this utility model is to provide a packaging box opening device to solve the above problems, as detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This utility model provides a packaging box opening device, including a frame, a first box conveyor belt fixedly connected to the frame for moving the packaging box into the frame, and two second box conveyor belts fixedly connected to the frame for moving the packaging box containing canned goods out of the frame.

[0008] The frame is fixedly connected to a first transverse slide and a second transverse slide. The moving ends of the first transverse slide and the second transverse slide are respectively fixedly connected to a push rod and a T-shaped stop rod. The second transverse slide and the T-shaped stop rod cooperate to move the packaging box on the first box conveyor belt to the second box conveyor belt.

[0009] Two opening components are fixedly connected to the frame for opening the packaging box;

[0010] A can conveyor belt corresponding to the first container conveyor belt is fixedly connected to the frame.

[0011] Using the above-mentioned packaging box opening device, after the equipment is started, the first box conveyor belt starts to run, continuously transporting empty packaging boxes to the designated position in the frame at a stable speed.

[0012] When the packaging box arrives at the designated area, the moving end of the second transverse slide moves the T-shaped stop bar horizontally, pushing the packaging box onto the second box conveyor belt. The two second box conveyor belts and two spreading components work together to improve the packing efficiency.

[0013] Subsequently, the two expansion components corresponding to the second box conveyor belt begin to work. The two rotating shafts in each expansion component rotate synchronously in opposite directions, causing the support plates fixed on the rotating shafts to flip outward from the initial closed state. As the rotating shafts continue to rotate, the two support plates gradually flip to a horizontal position, cooperating with each other to form a flat, stable platform with an area adapted to the size of the cans. This platform can not only support the subsequent cans, but also fully expand the internal space of the packaging box, preparing for the loading of the cans.

[0014] The moving end of the first transverse slide drives the push rod to move in the transverse direction. When the push rod moves to align with the rows of cans placed on the can conveyor belt, the push rod pushes forward, smoothly moving the rows of cans from the can conveyor belt onto the platform formed by the support plate.

[0015] The cylinder on the frame extends, driving the L-shaped stop bar at the movable end to move forward along the length of the first box conveyor belt. It works in conjunction with the T-shaped stop bar, which is also in the working preparation state, to accurately and firmly clamp and position the packaging box from both sides, ensuring that the packaging box remains stable during subsequent operations and will not shift or shake.

[0016] The lifting cylinder is activated, and the vacuum suction cup fixed at its lifting end descends to contact the can. It firmly holds the can through the principle of vacuum adsorption and accurately places it into the pre-opened packaging box below.

[0017] Preferably, the two spreading components correspond to the two second box conveyor belts respectively.

[0018] Preferably, the spreading assembly includes two rotating shafts with opposite rotation directions, and a support plate is fixedly connected to the rotating shaft. The two support plates cooperate to form a platform for supporting the cans. The first transverse slide cooperates with the push rod to move the cans on the can conveyor belt to the support plate.

[0019] Preferably, the upper sides of the first and second box conveyor belts are at the same height.

[0020] Preferably, two lifting cylinders are fixedly connected to the frame, and vacuum suction cups are fixedly connected to the lifting ends of the lifting cylinders. The two vacuum suction cups correspond to the two second box conveyor belts respectively.

[0021] Preferably, two cylinders are fixedly connected to the frame, and an L-shaped stop bar is fixedly connected to the movable end of the cylinder. The L-shaped stop bar and the T-shaped stop bar cooperate to clamp the packaging box.

[0022] Preferably, the extension and retraction direction of the cylinder is set along the length direction of the first housing conveyor belt.

[0023] Preferably, the conveying direction of the second box conveyor belt is the same as that of the first box conveyor belt, and the second box conveyor belt can extend the conveying length of the first box conveyor belt.

[0024] Preferably, the bottom of the frame has multiple bolt holes.

[0025] Preferably, a housing is fixedly connected to the frame.

[0026] The beneficial effects are:

[0027] 1. This utility model integrates multiple packaging processes such as box conveying, opening, can loading, and transfer into one unit. Through the coordinated operation of components such as the first box conveyor belt, the second box conveyor belt, the opening assembly, and the transverse slide, the packaging process is automated and continuous. The cross-operation of the two second box conveyor belts and the two opening assemblies significantly improves the boxing efficiency. Compared with traditional equipment or manual operation, it can increase the packaging output per unit time, effectively meeting the needs of large-scale production in enterprises.

[0028] 2. The packaging box is clamped using L-shaped and T-shaped stops, achieving precise positioning and reducing shaking or displacement caused by positioning deviations. The first transverse slide and push rod precisely control the pushing of the cans, ensuring they are neatly arranged on the support platform. A lifting cylinder drives a vacuum suction cup, using vacuum adsorption to precisely grasp and place the cans, preventing tipping and damage, and improving the consistency and stability of product packaging quality.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] See Figures 1-4 As shown, this utility model provides a packaging box opening device, including a frame 1, a first box conveyor belt 3 fixedly connected to the frame 1 for moving the packaging box into the frame 1, and two second box conveyor belts 4 fixedly connected to the frame 1 for moving the packaging box containing canned goods out of the frame 1.

[0038] A first transverse slide 8 and a second transverse slide 11 are fixedly connected to the frame 1. A push rod 9 and a T-shaped stop rod 10 are fixedly connected to the moving ends of the first transverse slide 8 and the second transverse slide 11, respectively. The second transverse slide 11 and the T-shaped stop rod 10 cooperate to move the packaging box on the first box conveyor belt 3 to the second box conveyor belt 4.

[0039] Both the first transverse slide 8 and the second transverse slide 11 are linear module slides, whose structure includes a slide rail, a slider, a lead screw, and a servo motor. The lead screw passes through the slider, and the servo motor is connected to one end of the lead screw through a coupling. When the servo motor rotates, it drives the lead screw to rotate, thereby driving the slider to move linearly along the slide rail. The push rod 9 is vertically fixed to the upper surface of the slider of the first transverse slide 8 by bolts, and the T-shaped stop rod 10 is fixed to the slider of the second transverse slide 11 through an L-shaped adapter plate to ensure that the actuator is stable and does not loosen during high-speed movement.

[0040] Two support components 5 are fixedly connected to the frame 1 for opening the packaging box;

[0041] A can conveyor belt 2 corresponding to the first box conveyor belt 3 is fixedly connected to the frame 1.

[0042] As an optional implementation, the two spreading components 5 correspond to the two second box conveyor belts 4 respectively.

[0043] The spreading assembly 5 includes two rotating shafts 6 with opposite rotation directions. Support plates 7 are fixedly connected to the rotating shafts 6. The two support plates 7 cooperate to form a platform for supporting the cans. The first transverse slide 8 cooperates with the push rod 9 to move the cans on the can conveyor belt 2 onto the support plates 7.

[0044] The rotating shaft 6 is mounted in a bearing housing on the side wall of the frame 1 via a deep groove ball bearing. The bearing housing adopts a detachable flange structure for easy maintenance and replacement. The support plate 7 is fixed to one end of the rotating shaft 6 by welding. The other end of the rotating shaft 6 extends out of the frame 1 and is equipped with a synchronous pulley. The synchronous pulleys of the two spreading components 5 are connected by a synchronous belt and driven by a servo motor to ensure that the two rotating shafts 6 rotate in opposite directions and at the same speed, so as to realize the synchronous and smooth rotation of the support plate 7. The power source of the rotating shaft 6 can be an independent servo motor.

[0045] The upper heights of the first box conveyor belt 3 and the second box conveyor belt 4 are the same.

[0046] Two lifting cylinders 14 are fixedly connected to the frame 1. Each lifting cylinder 14 has a vacuum suction cup 15 fixedly connected to its lifting end. The two vacuum suction cups 15 correspond to the two second box conveyor belts 4 respectively.

[0047] The lifting cylinder 14 is a guide rod cylinder, and its cylinder body is fixed to the top crossbeam of the frame 1 via a U-shaped mounting bracket. The vacuum suction cup 15 is connected to the vacuum generator via an air pipe, and a quick-connect connector is provided in the middle of the air pipe for easy disassembly and assembly. The vacuum generator is controlled independently by a PLC control system. When the lifting cylinder 14 lowers the vacuum suction cup 15 to contact the can, the PLC sends a signal to start the vacuum generator, forming a vacuum suction force within 0.3 seconds. The suction force can reach 50N, ensuring stable gripping and placement of the can.

[0048] The equipment uses a PLC (Programmable Logic Controller) as the core control unit, specifically a Siemens S7-1200. The PLC connects to various actuators via input / output modules.

[0049] Input signals: Through-beam photoelectric sensors are installed in the positioning area of ​​the first box conveyor belt 3 and at the can position of the can conveyor belt 2 to detect the position signals of the packaging box and the can; magnetic switches are installed at both ends of the cylinder body of cylinder 12 and lifting cylinder 14 to provide feedback on the extension and retraction status of the cylinder.

[0050] Output signals: control the operation of components such as the servo motor driver, solenoid valve, and vacuum generator. The servo motor driver receives pulse signals from the PLC to control the movement distance and speed of the slide table; the solenoid valve controls the air passage of cylinder 12 and lifting cylinder 14; the vacuum generator is controlled to start and stop by the PLC digital output port.

[0051] After the equipment is started, the PLC initializes all parameters, and the first box conveyor belt 3 and the can conveyor belt 2 run at the set speed.

[0052] When the photoelectric sensor detects that the packaging box has reached the positioning area, the PLC controls the cylinder 12 to extend, and the L-shaped stop bar 13 and the T-shaped stop bar 10 clamp the packaging box. At the same time, the second transverse slide 11 drives the T-shaped stop bar 10 to push the packaging box to the second box conveyor belt 4.

[0053] The pivot 6 of the support component 5 is rotated under the drive of the servo motor, and the support plate 7 opens the packaging box. At this time, the first horizontal slide 8 drives the push rod 9 to push the can to the support plate 7 platform.

[0054] The vacuum suction cup 15 descends under the action of the lifting cylinder 14 to adsorb the can. The PLC controls the vacuum suction cup 15 to rise and move above the packaging box, accurately releasing the can to complete the loading.

[0055] The second conveyor belt 4 removes the canned goods from the packaging box, and the PLC controls all components to reset, entering the next cycle.

[0056] Two cylinders 12 are fixedly connected to the frame 1. An L-shaped stop bar 13 is fixedly connected to the movable end of the cylinder 12. The L-shaped stop bar 13 and the T-shaped stop bar 10 cooperate to clamp the packaging box.

[0057] The extension and retraction direction of cylinder 12 is set along the length direction of the first box conveyor belt 3.

[0058] The conveying direction of the second box conveyor belt 4 is the same as that of the first box conveyor belt 3, and the second box conveyor belt 4 can extend the conveying length of the first box conveyor belt 3.

[0059] Multiple bolt holes are provided at the bottom of frame 1.

[0060] A housing 16 is fixedly connected to the frame 1.

[0061] The multiple bolt holes at the bottom of the frame 1 allow for easy connection of the equipment to other equipment on the production line, ensuring the stability of the equipment during operation. The housing 16 fixedly connected to the frame 1 protects the various internal components, effectively reducing interference from external dust, debris, and unexpected factors, and ensuring long-term, stable, and reliable operation of the equipment.

[0062] With the above structure, after the equipment is started, the first box conveyor belt 3 starts to run, continuously transporting empty packaging boxes to the designated position in the frame 1 at a stable speed.

[0063] When the packaging box arrives at the designated area, the moving end of the second transverse slide 11 drives the T-shaped stop bar 10 to move horizontally, pushing the packaging box onto the second box conveyor belt 4. The two second box conveyor belts 4 and the two spreading components 5 work together to improve the packing efficiency.

[0064] Subsequently, the two expansion components 5 corresponding to the second box conveyor belt 4 begin to work. The two rotating shafts 6 in each expansion component 5 rotate synchronously in opposite directions, causing the support plates 7 fixed on the rotating shafts 6 to flip outward from the initial closed state. As the rotating shafts 6 continue to rotate, the two support plates 7 gradually flip to the horizontal position, cooperating with each other to form a flat, stable platform with an area adapted to the size of the cans. This platform can not only support the subsequent cans, but also fully expand the internal space of the packaging box, preparing for the loading of the cans.

[0065] The moving end of the first transverse slide 8 drives the push rod 9 to move in the transverse direction. When the push rod 9 moves to align with the rows of cans placed on the can conveyor belt 2, the push rod 9 pushes forward, smoothly moving the rows of cans from the can conveyor belt 2 onto the platform formed by the support plate 7.

[0066] The cylinder 12 on the frame 1 extends, driving the L-shaped stop bar 13 at the movable end to move forward along the length of the first box conveyor belt 3. It cooperates with the T-shaped stop bar 10, which is also in the working preparation state, to accurately and firmly clamp and position the packaging box from both sides, ensuring that the packaging box remains stable during subsequent operations and will not shift or shake.

[0067] When the lifting cylinder 14 is activated, the vacuum suction cup 15 fixed at its lifting end descends to contact the can, firmly sucks the can in place through the principle of vacuum adsorption, and accurately places it into the packaging box that has been opened below.

[0068] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
