Description

Technical Field

[0001] This utility model relates to the field of cardboard box production and processing technology, and in particular to a pressing mechanism for an automatic cardboard box gluing machine. Background Technology

[0002] The "pressing" process during corrugated box bonding is a core step in ensuring bonding quality, and its role goes far beyond simple adhesion. First, pressing eliminates air between the bonding surfaces through physical pressure, forcing the adhesive to penetrate deeply into the paper fibers and form a strong "mechanical anchor," thereby eliminating the illusion of a loose bond and fundamentally guaranteeing the bonding strength, enabling the bonded area to withstand the enormous external forces during stacking and transportation.

[0003] However, in the existing technology, excessive pressure is easy to occur during the compression process. The most direct risk is that it will cause physical damage to the carton itself, such as the carton being crushed or deformed, and the corners being dented. This not only seriously affects the appearance, but also weakens the overall compressive strength and stacking strength of the carton, causing it to collapse in subsequent storage, transportation and stacking because it cannot bear the weight of the upper layer, resulting in the crushing and damage of the contents. Utility Model Content

[0004] The purpose of this invention is to solve the problem of excessive pressure during the pressing process causing physical damage to the carton itself, and to propose a pressing mechanism for an automatic carton gluing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pressing mechanism for an automatic carton gluing machine, including a pressing frame, limit holes on both sides of the pressing frame, a pressing structure installed at the top of the inner cavity of the pressing frame, a pressing plate slidably connected to the inner side of the pressing frame, slide rods fixedly connected to both sides of the top of the pressing plate, and a second spring sleeved on the outer surface of the bottom end of the slide rod.

[0006] The clamping structure includes a central rod and a lifting plate. Two linkage rods are rotatably connected to both ends of the central rod. A roller is rotatably connected to one end of the linkage rod, and a rotating frame is rotatably connected to the other end of the linkage rod. One rotating frame is fixedly connected to the top of the inner cavity of the clamping frame, and the bottom of the other rotating frame is fixedly connected to the lifting plate. Limiting frames are fixedly connected to the top of the lifting plate and the top of the inner cavity of the clamping frame. The roller is slidably installed inside the limiting frame.

[0007] Preferably, a cylinder is fixedly installed on the top of the clamping frame, and a connecting rod is sleeved on the inner side of the cylinder output end.

[0008] Preferably, both ends of the connecting rod are rotatably connected to a drive frame, and both drive frames are slidably connected to the linkage rod.

[0009] Preferably, the limiting frame has a through hole in the middle, and one end of the linkage rod passes through the through hole.

[0010] Preferably, limit blocks are fixedly connected to the top of the pressing plate and the bottom of the lifting plate, and a first spring is sleeved on the outer surface of the two limit blocks.

[0011] Preferably, guide blocks are fixedly connected to both ends of the clamping plate, and the guide blocks are slidably connected to the limiting holes.

[0012] Preferably, the top of the slide rod passes through the lifting plate, and the slide rod is slidably connected to the lifting plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the pressure plate is used to uniformly press the corrugated paper to ensure the bonding effect. The central rod and the linkage rod cooperate to drive the roller to slide, thereby controlling the downward movement of the lifting plate. The movement of the lifting plate transmits pressure to the pressure plate. The pressure plate applies pressure to the corrugated paper, mainly relying on the elastic force of two springs. The first spring provides the basic pressure, and the second spring increases the pressure when the lifting plate moves. As the lifting plate continues to move downward, the pressure plate gradually approaches the corrugated paper. The second spring and the limiting block work together to adjust the applied pressure to ensure that the pressing force is moderate, avoid damage to the corrugated paper, and at the same time ensure the quality and stability of the bonding effect.

[0015] 2. In this utility model, the connecting rod is driven downward by the cylinder, which drives the drive frame to move synchronously. The drive frame applies torque to start the linkage rod. The four linkage rods move in coordination under the guidance of the central rod, thereby driving the lifting plate to move smoothly. The limit frame and rollers work together to ensure that the lifting plate moves within the predetermined range. The downward movement of the pressing plate is achieved through the guide block and its stability is ensured by the limit hole. The overall structural design ensures that all components work synchronously, improves the stability and accuracy of the system, avoids equipment failure due to uneven force or exceeding the limit range, and ensures that the device operates in a highly efficient and stable state.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4 As shown, this utility model provides a pressing mechanism for an automatic carton gluing machine, including a pressing frame 1, with limit holes 4 on both sides of the pressing frame 1, a pressing structure 2 installed at the top of the inner cavity of the pressing frame 1, a pressing plate 3 slidably connected to the inner side of the pressing frame 1, and slide rods 5 fixedly connected to both sides of the top of the pressing plate 3, with a second spring 51 sleeved on the outer surface of the bottom end of the slide rod 5.

[0024] The clamping structure 2 includes a central rod 29 and a lifting plate 28. Both ends of the central rod 29 are rotatably connected to two linkage rods 24. One end of the linkage rod 24 is rotatably connected to a roller 27, and the other end of the linkage rod 24 is rotatably connected to a rotating frame 241. One rotating frame 241 is fixedly connected to the top of the inner cavity of the clamping frame 1, and the bottom of the other rotating frame 241 is fixedly connected to the lifting plate 28. The top of the lifting plate 28 and the top of the inner cavity of the clamping frame 1 are both fixedly connected to a limit frame 25. The roller 27 is slidably installed inside the limit frame 25.

[0025] The specific setup and function of this embodiment will be described in detail below. First, the corrugated paper is placed at the bottom of the inner cavity of the clamping frame 1 as a reference position to provide stable support for the subsequent clamping process. On this basis, the clamping plate 3 performs uniform clamping treatment to ensure that the surface of the corrugated paper is subjected to uniform and appropriate pressure.

[0026] Throughout the clamping process, the linkage rods 24 at both ends of the central rod 29 are linked through an active mechanism. The linkage rods 24, through their movement and guided by the through hole 26, drive the rollers 27. The sliding movement of the rollers 27 within the limiting frame 25 is crucial for indirectly controlling the movement of the lifting plate 28. As the rollers 27 slide along the limiting frame 25, the linkage rods 24, through a certain mechanical transmission, cause the lifting plate 28 to gradually move downwards.

[0027] The downward movement of the lifting plate 28 indirectly affects the compression state of the second spring 51 by transmitting mechanical force, thereby driving the pressing plate 3 to press the corrugated paper downward in the vertical direction. During this process, the pressure exerted by the pressing plate 3 on the corrugated paper mainly comes from the elastic forces of two springs: the first spring 33 and the second spring 51. The first spring 33 is mainly responsible for providing the initial pressure, while the second spring 51 gradually increases the elastic force applied to the pressing plate 3 as the lifting plate 28 moves downward.

[0028] As the lifting plate 28 continues to move downward, the pressing plate 3 gradually approaches the surface of the corrugated paper. At this time, the second spring 51 and the limiting block 32 work together on the pressing plate 3 to adjust the applied pressure, ensuring that the pressure is not too high and will damage the corrugated paper, while also ensuring sufficient pressing force so that the bonding effect of the corrugated paper reaches the best.

[0029] Example 2: Figures 2-4 As shown, a cylinder 21 is fixedly installed on the top of the clamping frame 1, and a connecting rod 22 is sleeved on the inner side of the output end of the cylinder 21. Both ends of the connecting rod 22 are rotatably connected to drive frames 23, and both drive frames 23 are slidably connected to the linkage rod 24. A through hole 26 is opened in the middle of the limiting frame 25, and one end of the linkage rod 24 passes through the through hole 26. Limiting blocks 32 are fixedly connected to the top of the clamping plate 3 and the bottom of the lifting plate 28, and first springs 33 are sleeved on the outer surface of the two limiting blocks 32. Guide blocks 31 are fixedly connected to both ends of the clamping plate 3, and the guide blocks 31 are slidably connected to the limiting hole 4. The top end of the sliding rod 5 passes through the lifting plate 28, and the sliding rod 5 is slidably connected to the lifting plate 28.

[0030] The overall effect of this embodiment is that the cylinder 21, as the driving element, drives the connecting rod 22 to move downwards, which is the core of the overall system operation. Specifically, when the cylinder 21 drives the connecting rod 22 to move downwards, the connecting rod 22 transmits driving force to the two drive frames 23. These two drive frames 23 are linked together through a mechanical transmission structure and move synchronously.

[0031] As the drive frame 23 moves, it begins to apply torque to one of the linkage rods 24. At this time, the linkage rod 24, under the action of the driving force, begins to move, and by transmitting kinetic energy, causes the other linkage rods 24 to move as well. During this process, the four linkage rods 24, guided and coordinated by the central rod 29, simultaneously begin to move in a coordinated manner. This linkage mechanism ensures that all components work synchronously, thereby improving the overall efficiency and stability of the system.

[0032] Next, the coordinated movement of the four linkages 24, combined with the cooperation between the limit frame 25 and the rollers 27, ensures the smooth movement of the lifting plate 28. When the lifting plate 28 begins to move, the limit frame 25 and the rollers 27, through precise mechanical coordination, limit the displacement range of the lifting plate 28, preventing abnormalities caused by excessive movement or instability.

[0033] Furthermore, the clamping plate 3 also plays a crucial role in the system. When the clamping plate 3 begins to move downwards, it is connected to the guide block 31 and moves synchronously. The guide block 31 ensures that the clamping plate 3 moves smoothly along the predetermined track, preventing deviation caused by external interference or uneven force. To further ensure the stability of the clamping plate 3 during lifting and lowering, a limiting hole 4 is also provided in the system design. This limiting hole 4 effectively limits the lifting and lowering range of the clamping plate 3, thereby enhancing the accuracy and stability of the system during operation.

[0034] The device's operation and working principle are as follows: During the corrugated paper bonding process, it is first placed at the bottom of the inner cavity of the clamping frame 1 and clamped by the clamping plate 3. During this process, the linkage rods 24 at both ends of the central rod 29 begin to move. Due to the constraint of the through hole 26, the linkage rods 24 drive the rollers 27 to slide inside the limiting frame 25, thereby indirectly controlling the movement of the lifting plate 28. As the lifting plate 28 gradually moves downward, the force is transmitted to the clamping plate 3 through the second spring 51, causing it to move downward.

[0035] When the pressing plate 3 approaches the corrugated paper, the pressure it applies comes from the elastic force of the first spring 33 and the second spring 51. As the lifting plate 28 continues to move downward, the second spring 51 and the limiting block 32 work together to adjust the force applied to the pressing plate 3, thereby controlling the pressing force. This mechanism can both prevent damage to the corrugated paper due to excessive pressure and ensure sufficient pressing force.

[0036] When cylinder 21 drives connecting rod 22 to move downward, connecting rod 22 synchronously drives two drive frames 23 to move. When drive frame 23 applies driving force to one of the linkage rods 24, the linkage rod 24 begins to move, and under the linkage action of central rod 29, all four linkage rods 24 move in tandem. With the cooperation of limit frame 25 and roller 27, lifting plate 28 moves accordingly. During the downward movement of pressing plate 3, it drives guide block 31 to move together, and under the constraint of limit hole 4, the stability of the lifting action of pressing plate 3 is ensured.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
