Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging material production technology, specifically to a material discharge structure for a carton nailing device. Background Technology
[0002] In the corrugated box manufacturing industry, the unloading process after the stapling device completes the stapling operation is crucial. Existing corrugated box stapling devices typically require flattening the stapled boxes during unloading to ensure flatness and stability, facilitating subsequent storage, transportation, and use. However, current flattening methods have significant technical drawbacks. During the conveying and supporting of the boxes, the flattening components, due to direct contact with the box's interior and their less-than-smooth or harder surfaces, are prone to scratching the internal structure. This not only affects the box's appearance but may also reduce its strength and lifespan. Furthermore, existing flattening methods often fail to achieve uniform and effective flattening, resulting in localized bulges or unevenness, failing to meet the requirements of high-quality corrugated box production. This suboptimal flattening effect not only impacts product quality but may also cause a series of problems in subsequent processes, increasing production costs and time. Additionally, the nails used during the binding process may also damage the boxes. For example, nails may protrude from the surface of the cardboard box, scratching operators or damaging other items during subsequent handling or transportation; or the nails may not be fully driven into the box, resulting in an unstable internal structure and affecting its use. Therefore, developing a feeding structure that can achieve efficient and non-destructive flattening during the feeding of cardboard boxes by the nailing device, while avoiding damage to the cardboard boxes from nails, has become a pressing technical problem for the cardboard box manufacturing industry.

A second upper plate position is formed between the two second vertical carriages, and the main surface of the other carton prefabricated board is used for lifting and sliding on the second upper plate position.
[0008] A first folding edge is formed between the first vertical carriage and the second vertical carriage that are longitudinally adjacent, and the two first folding edges are respectively used to accommodate the side folding surfaces of the two carton prefabricated panels;
[0009] A swinging ejector is provided, which is oscillating relative to the first vertical slide. The swinging ejector has a supporting surface, which is used to slide against the main surface corresponding to the finished carton.
[0010] As a further technical solution, it also includes:
[0011] The connector has two ends respectively mounted on the two first vertical slides, and the swinging discharge component is swingingly mounted on the connector and is located at the upper end of the first vertical slide.
[0012] As a further technical solution, the swing axis of the swinging discharge component is transverse, the side of the swinging discharge component near the swing axis has a discharge inlet, and the side away from the swing axis has a discharge outlet, and the first upper plate position leads to the discharge inlet.
[0013] As a further technical solution, it also includes:
[0014] A swinging flattening component is provided on one side of the swinging discharge component, with the swinging axis being vertical. The swinging flattening component is used to slide against the side folding surface corresponding to the finished carton. The swinging flattening component is configured such that, after swinging, it pushes the side folding surface to swing in the direction of the main surface, flattening the finished carton.
[0015] As a further technical solution, it also includes:
[0016] The fourth suction cup is slidably disposed on the oscillating discharge component, and the sliding direction is tangential to the oscillation of the oscillating discharge component, and the fourth suction cup penetrates the supporting surface.
[0017] As a further technical solution, it also includes:
[0018] A first linear drive is disposed on the oscillating discharge member. The output end of the first linear drive is hinged to one end of the oscillating flattening member.

[0021] As a further technical solution, the swing angle range of the swinging discharge component is 0~180°.
[0022] The working principle and beneficial effects of this utility model are as follows:
[0023] In this invention, firstly, two prefabricated cardboard boxes are placed on the first and second upper plate positions respectively, ensuring the main surface of the prefabricated box is flush with the upper plate position. Then, a lifting device slides the prefabricated box up and down on its respective upper plate position, adjusting it to a suitable height to prepare for subsequent folding and binding. During the lifting process, the side folding surface of the cardboard box prefabricated box gradually approaches the first folding edge formed between the longitudinally adjacent first and second vertical slides. As the prefabricated box continues to descend, the side folding surface automatically enters and is accommodated within the first folding edge, thus achieving precise folding positioning and ensuring neat folds in the cardboard box. Once the cardboard box prefabricated box is accurately positioned on the first and second upper plate positions and within the first folding edge, it is bound using a binding device. When the finished cardboard box moves out from the first upper plate position, it contacts the supporting surface of the oscillating ejector. With the natural oscillation of the oscillating ejector, the cardboard box is smoothly conveyed outward along the supporting surface. The special treatment of the support surface reduces friction with the carton surface, preventing scratches or damage and effectively protecting the carton's appearance. The oscillating motion of the oscillating ejector coordinates with the carton's movement, making the ejection process smoother, reducing the possibility of jams and stalls, and improving production efficiency. Due to the adaptability of the support surface, it can well support finished cartons of different sizes and shapes, increasing the equipment's versatility. Attached Figure Description

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0033] Reference Figures 1-3This utility model provides an embodiment of a carton nailing device with a material discharge structure. The carton prefabricated board has a main surface 101 and a side folding surface 102, including two first vertical slides 2. A first upper plate position 201 is formed between the two first vertical slides 2, and the main surface 101 of one carton prefabricated board is used for lifting and sliding on the first upper plate position 201. There are two second vertical slides 3, which are located on one side of the longitudinal direction of the first vertical slides 2, and a second upper plate position is formed between the two second vertical slides 3. 301, the main surface 101 of another prefabricated carton board is used for lifting and sliding on the second upper plate position 301; a first folding edge position 302 is formed between the first vertical slide 2 and the second vertical slide 3 that are longitudinally adjacent, and the two first folding edge positions 302 are respectively used to accommodate the side folding surfaces 102 of the two prefabricated carton boards; the swinging discharge component 23 is swinging relative to the first vertical slide 2, and the swinging discharge component 23 has a supporting surface 2301, which is used to slide and abut against the main surface 101 corresponding to the finished carton.
[0034] Furthermore, it also includes a connector 22, with both ends of the connector 22 respectively disposed on the two first vertical slides 2, and the swinging discharge component 23 swingingly disposed on the connector 22, and both located at the upper end of the first vertical slides 2.
[0035] In this embodiment, firstly, two prefabricated cardboard boxes are placed on the first upper plate position 201 and the second upper plate position 301, respectively, so that the main surface 101 of the prefabricated box is in contact with the upper plate position. Then, the prefabricated box is slid up and down on its respective upper plate position using a lifting device to adjust it to a suitable height position, preparing for subsequent folding and binding. During the lifting process, the side folding surface 102 of the cardboard box prefabricated box will gradually approach the first folding edge position 302 formed between the longitudinally adjacent first vertical slide 2 and second vertical slide 3. As the prefabricated box continues to descend, the side folding surface 102 will automatically enter and be accommodated in the first folding edge position 302, thereby achieving precise folding positioning and ensuring that the folding edge of the cardboard box is neat. After the cardboard box prefabricated box is accurately positioned on the first upper plate position 201 and the second upper plate position 301 and in the first folding edge position 302, it is bound using a binding device.
[0036] When the finished carton moves out from the first upper plate position, it contacts the supporting surface 2301 of the oscillating ejector 23. With the natural oscillation of the oscillating ejector 23, the carton is smoothly conveyed outward along the supporting surface 2301. The stable connection of the connector 22 ensures the stability of the oscillating ejector 23 during operation, preventing the carton from shaking or falling during conveying, thus ensuring reliable conveying. The special treatment of the supporting surface 2301 reduces friction with the carton surface, preventing scratches or damage and effectively protecting the carton's appearance. The oscillating motion of the oscillating ejector 23 coordinates with the movement of the carton, making the carton ejection process smoother, reducing the possibility of jamming and stagnation, and improving production efficiency. Due to the adaptability of the supporting surface 2301, it can well support finished cartons of different sizes and shapes, increasing the versatility of the equipment.
[0037] Furthermore, the swing axis of the swing discharge component 23 is transverse, the side of the swing discharge component 23 near the swing axis has a discharge inlet 2302, and the side away from the swing axis has a discharge outlet 2303, and the first upper plate position 201 leads to the discharge inlet 2302.
[0038] In this embodiment, the finished carton smoothly enters the feed inlet from the first upper plate position, and is then discharged from the discharge outlet as the swing shaft oscillates laterally. The rational design of the feed inlet and discharge outlet, along with the layout of the lateral swing shaft, allows the carton to enter quickly and smoothly from the feed inlet and exit smoothly from the discharge outlet, significantly improving discharge efficiency and meeting the needs of large-scale production. The design of the lateral swing shaft reduces vertical space occupation, allowing for more flexible equipment arrangement within limited space, especially suitable for space-constrained production environments. The precise alignment of the first upper plate position with the feed inlet ensures the accuracy of the carton entering the swing discharge component 23, reducing paper jams or conveying failures caused by positional deviations and improving production stability. The efficient discharge method reduces energy loss during carton conveying, lowering equipment operating costs and also helping to reduce equipment wear and heat generation. This structural design can adapt to cartons of different sizes and shapes; both large and small cartons can be smoothly conveyed through the swing discharge component 23, enhancing the equipment's versatility and adaptability.
[0039] Furthermore, it also includes a swing flattening component 24, which is swing-mounted on one side of the swing discharge component 23. The swing axis is vertical. The swing flattening component 24 is used to slide against the side folding surface 102 corresponding to the finished carton. The swing flattening component 24 is configured such that after swinging, it pushes the side folding surface 102 to swing towards the main surface 101 to flatten the finished carton.
[0040] In this embodiment, when the finished carton reaches the designated position, the swinging flattening component 24 swings vertically, contacts the side folding surface of the carton, and applies pressure, pushing the side folding surface towards the main surface to achieve the flattening operation. Precise vertical swinging and reasonable pressure application ensure that the side folding surface of the finished carton is pressed evenly and effectively towards the main surface, achieving an ideal flattening effect and improving the flatness and stability of the carton. Compared with traditional flattening methods, this design avoids scratches and damage to the inside of the carton, ensuring the integrity and quality of the carton and reducing the defect rate. The automated swinging flattening action is fast and efficient, greatly shortening the flattening process time, thereby improving the efficiency of the entire production process and increasing output per unit time. It can be flexibly adjusted according to cartons of different sizes and shapes, achieving good flattening effects for cartons of various specifications, enhancing the versatility and applicability of the equipment. It replaces manual flattening operations, reducing the labor intensity of workers and allowing them to focus on other more important production processes, improving overall production efficiency.
[0041] Furthermore, it also includes a fourth suction cup 25, which is slidably disposed on the swinging discharge member 23, and the sliding direction is tangential along the swinging direction of the swinging discharge member 23, and the fourth suction cup 25 penetrates the support surface 2301.
[0042] In this embodiment, during the carton ejection process, the fourth suction cup 25 slides tangentially, adaptively adjusting according to the carton's position and posture, and firmly adsorbs the carton through the portion penetrating the support surface 2301. The adsorption effect of the fourth suction cup 25 ensures that the carton maintains a stable position during the swinging ejection process, preventing displacement due to shaking or external interference, thus improving the accuracy and reliability of ejection. The tangential sliding design allows the fourth suction cup 25 to flexibly respond to different states and movement trajectories of the carton, maintaining effective control even during rapid ejection or when encountering external interference. Stable adsorption and fixation help maintain the shape and structural integrity of the carton, preventing deformation or damage during ejection, thereby improving product quality and consistency. It also prevents accidental drops of the carton during ejection, reducing safety hazards and providing a safer working environment for operators.
[0043] Furthermore, it also includes a first linear drive 26, which is disposed on the oscillating discharge member 23. The output end of the first linear drive 26 is hinged to one end of the oscillating flattening member 24. The first linear drive 26 is configured such that the oscillating flattening member 24 oscillates after the output end extends or retracts.
[0044] In this embodiment, the first linear drive unit 26 precisely extends and retracts its output end according to a preset program or sensor feedback, driving the swinging flattening unit 24 to perform precise swinging movements. Advanced drive technology and precise extension / retraction control ensure that the swing angle and speed of the swinging flattening unit 24 can be accurately adjusted to meet the subtle differences in flattening requirements for different cartons, improving flattening accuracy and quality. The rapid-response extension / retraction of the output end can significantly shorten the flattening time, improve production efficiency, and adapt to the pace of large-scale production. The automated drive method reduces manual intervention in the flattening process, reduces the impact of human error, and improves production consistency and stability. It can quickly adapt to changes in production conditions and carton specifications by adjusting drive parameters, enhancing the flexibility and adaptability of the equipment.
[0045] Furthermore, it also includes a second linear drive 27, which is disposed on the connector 22. The output end of the second linear drive 27 is hinged to the oscillating discharge member 23. The second linear drive 27 is configured such that when the output end extends or retracts, it drives the oscillating discharge member 23 to oscillate.
[0046] In this embodiment, when the oscillating ejector 23 needs to be driven to oscillate, the second linear drive 27 receives a control signal and its output end extends or retracts. The extension or retraction of the output end drives the oscillating ejector 23, which is hinged to it, to oscillate accordingly. This significantly improves the ejection speed and efficiency, meeting the demands of high-production-rate environments. The extension or retraction of the output end can be precisely controlled, thereby achieving precise adjustment of the oscillation angle and speed of the oscillating ejector 23, ensuring that each oscillation accurately delivers the carton to the designated position. The reliable installation method and high-quality hinge structure enable the second linear drive 27 to maintain stable performance during operation, reducing malfunctions caused by vibration or impact and improving the overall stability of the equipment. The oscillation amplitude and frequency of the oscillating ejector 23 can be flexibly adjusted according to different production requirements and carton specifications, adapting to various complex and changing production conditions.
[0047] Furthermore, the swing angle range of the swinging discharge component 23 is 0~180°.
[0048] In this embodiment, during operation, the vertically oriented carton, after being bound, reaches the position of the oscillating ejector 23. When the carton contacts the oscillating ejector 23, the ejector 23 gradually increases its oscillation angle from an initial position close to 0° vertically. For example, it first oscillates to 90° to lay the vertical carton down, then continues to oscillate to a suitable downward conveying angle, such as 135°, and may eventually reach 180°, to achieve smooth downward conveying of the carton. The ability to precisely lay down the vertical carton and adjust it to the optimal conveying angle ensures smooth and accurate downward conveying, improving the accuracy and reliability of the ejection. Reasonable angle adjustment reduces obstruction and jamming during conveying, greatly improving conveying efficiency and meeting the needs of high-efficiency production. The 0~180° oscillation angle range can adapt to conveying needs at different heights and positions, easily facilitating connection with lower conveyor belts or direct conveying to specific collection areas. Smooth laying and conveying actions reduce impact and collisions on the carton, protecting it from damage and ensuring product quality. Operators can flexibly select and control the swing angle of the swinging discharge component 23 according to the actual production situation and conveying requirements, making operation simple and convenient.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
