Description

Technical Field

[0001] This utility model relates to the field of nailing machine technology, and in particular to a lifting device for a nailing mechanism. Background Technology

[0002] In the modern packaging industry, cardboard boxes, as a widely used packaging container, receive significant attention for their production efficiency and quality. As a key post-processing equipment in cardboard box production, the stapling machine plays a crucial role in sealing the boxes. With the continuous upgrading of cardboard box production equipment, more and more integrated stapling and gluing machines are appearing on the market today. This type of equipment can independently complete the stapling and gluing processes on the same machine. Specifically, the stapling and gluing mechanisms are staggered along the corrugated cardboard conveyor line.

[0003] Because these two mechanisms have different characteristics, when performing a carton-stitching operation, only the carton-stitching mechanism needs to be activated. When performing a carton-gluing operation alone, the carton still needs to pass through the carton-stitching machine. Although the carton-stitching mechanism does not obstruct the carton conveying, the conveying speed of the carton will be slowed down when it passes through the guide unit of the carton-stitching mechanism, which in turn affects the overall efficiency of the carton-gluing production line.

[0004] To meet the ever-evolving needs of the packaging industry and overcome the shortcomings of existing carton stapling machine lifting mechanisms, developing a highly efficient, stable, and conveniently adjustable height lifting mechanism for carton stapling machines is of significant practical importance. This will not only improve carton production efficiency and ensure production safety, but also enhance worker comfort and reduce labor intensity, thereby promoting technological progress and development throughout the packaging industry. Summary of the Invention

[0005] Technical problem to be solved: The purpose of this utility model is to provide a lifting mechanism for a box-nailing machine, so as to solve the problem in the background that the box-nailing and gluing processes cannot be separated.

[0006] Technical solution

The chain drive mechanism consists of a sprocket, a chain, bolts, and a drive motor. The position of the sprocket can be changed via an adjusting bolt on the upper part of the mounting frame. The drive motor is connected to the sprocket on the other side for lifting power. The screw lifting mechanism includes a screw and a nut. The screw is rotatably mounted on the sprocket, and a nut is installed at its upper end, which is fixedly mounted on the nailing mechanism mounting frame. A guide rail is installed between the nailing mechanism mounting frame and the frame.

[0008] Preferably, the frame is provided with a bottom frame for supporting the chain drive mechanism and the lead screw lifting mechanism, and the frame is provided with columns for supporting the nailing machine mounting frame.

[0009] Preferably, the lifting mechanism of the nailing machine is characterized in that three sprockets on both sides of the chain drive mechanism are horizontally installed, and the remaining four sprockets are connected to the lead screw.

[0010] Preferably, in the lifting mechanism of the nailing machine, the outer sprocket of the chain drive mechanism is installed in a straight groove by screws, and the position of the outer sprocket can be adjusted by screws. The change of the sprocket position can control the tension of the chain.

[0011] Preferably, in the nailing machine lifting mechanism, the outer sprocket of the three sprockets on the other side of the chain transmission mechanism is connected to the drive motor.

[0012] Preferably, the lifting mechanism of the nailing machine is characterized in that the screw lifting mechanism consists of 4 screws connected to sprockets, and the upper end of the screws is mounted on the nailing mechanism mounting frame by nuts.

[0013] Preferably, the lifting mechanism of the nailing machine is characterized in that a guide rail is provided between the frame column and the nailing mechanism.

[0014] Beneficial effects

[0015] Compared to existing technologies, the advantages of this invention are as follows: This invention allows for the separation of nailing and gluing operations, which not only improves the efficiency of carton production but also reduces costs. Equipped with a high-precision displacement sensor, it enhances production stability, monitors the lifting position in real time and feeds feedback to the control system, ensuring a smooth and stable lifting process without shaking. The nailing position deviation is controlled within 0.5mm, effectively reducing the scrap rate of cartons caused by inaccurate positioning and increasing the product qualification rate to over 99.5%.

[0016] Installation and maintenance are simpler. The modular design allows each component of the lifting mechanism to be disassembled and replaced independently. Routine maintenance does not require professional tools, the parts are highly interchangeable, the procurement and replacement costs are reduced by 20%, and the equipment downtime for maintenance is significantly shortened.

[0027] Reference Figures 1-6 The present invention provides a technical solution: a lifting mechanism for a nailing machine, comprising a frame 1, a chain transmission mechanism 2, a screw lifting mechanism 3, a nailing mechanism mounting frame 4, and a drive motor 5. The components work together to achieve stable lifting of the nailing mechanism, solving the problem that the nailing and gluing processes cannot be separated.

[0028] The frame 1 serves as the supporting foundation for the entire mechanism and consists of two parts: the bottom frame and the columns. It is used to install and fix the lower components of the chain drive mechanism 2 and the screw lifting mechanism 3. The columns are vertically arranged on both sides of the bottom frame and are made of square steel pipes. They have guide grooves on their inner sides to cooperate with the guide rails 33 to achieve stable lifting and lowering guidance of the nail box mechanism mounting frame 4.

[0029] The chain drive mechanism 2 consists of 10 sprockets 21, a chain 22, and adjusting bolts 23. Three sprockets 21 are horizontally mounted at the bottom of one side of the frame 1 in a triangular arrangement. The outer sprocket is screwed into a pre-set straight groove in the frame 1. Loosening the screw allows the sprocket to move along the groove, adjusting the tension of the chain 22. After adjustment, the screw is tightened to secure it. The other four sprockets 21 are fixedly connected to the lower end of the lead screw 31, forming a closed transmission chain with the three horizontally mounted sprockets via the chain 22. The drive motor 5 is connected to the outer sprocket on the other side of the three horizontally mounted sprockets via a coupling, providing power to the entire transmission system.

[0030] The lead screw lifting mechanism 3 includes four lead screws 31, nuts 32 adapted to the lead screws, and guide rails 33. The lower end of each lead screw 31 is rotatably mounted on a bearing connected to a sprocket 21, and the upper end passes through the nut 32 fixed to the nail box mechanism mounting frame 4. The guide rail 33 adopts a slider-rail structure; the rail is fixedly mounted inside the column of the frame 1, and the slider is fixedly connected to the side of the nail box mechanism mounting frame 4 to ensure the verticality and stability of the mounting frame during lifting.

[0031] The nailing mechanism mounting frame 4 adopts a rectangular frame structure, with the side rigidly connected to the slider of the guide rail 33. The working parts of the nailing mechanism (such as nail heads, feeding devices, etc.) are installed at the bottom. The overall structure can be raised and lowered synchronously along the lead screw 31 with the nut 32.

[0032] Working principle

[0033] When the height of the nailing mechanism needs to be adjusted, the drive motor 5 is started. The motor output torque is transmitted to the four sprockets 21 connected to the lead screw 31 through the chain transmission mechanism 2, causing the lead screw 31 to rotate synchronously. Since the nut 32 is fixedly connected to the nailing mechanism mounting frame 4 and cannot rotate with the lead screw 31 under the constraint of the guide rail 33, the rotational motion of the lead screw 31 is converted into the linear lifting motion of the nut 32. This, in turn, drives the nailing mechanism mounting frame 4 and the nailing mechanism above it to rise and fall smoothly along the guide rail 33 until the desired working position is reached, at which point the drive motor 5 is turned off. Through the above structure, the height separation of the nailing mechanism and the gluing mechanism can be achieved, meeting the requirement of independent operation for both.

[0034] This invention utilizes chain transmission to achieve synchronous drive of multiple lead screws, coupled with guide rails, ensuring stability and precision during the lifting process. Simultaneously, the sprocket position adjustment structure facilitates maintenance of chain tension, extending the mechanism's service life. It also allows the nailing and gluing mechanisms to operate independently, thus increasing work efficiency.

[0035] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
