Description

Technical Field

[0001] This utility model relates to the field of paper card processing equipment technology, and in particular to a slitting device for paper card processing. Background Technology

[0002] In the paper card processing process, slitting equipment needs to cut the paper cards to the required specifications using a blade. Existing paper card slitting equipment typically includes a frame with a worktable for placing the paper cards and a slitting drive mechanism for driving the blade. The blade is connected to the output end of the slitting drive mechanism, which drives the blade to move or rotate to achieve the slitting operation. However, after long-term use, the blade is prone to wear or dulling and needs to be replaced. In existing equipment, the blade is often directly fixed to the output end of the slitting drive mechanism with multiple bolts. Replacement requires tools to remove each bolt one by one, and then tightening them one by one after replacement. The whole process is cumbersome and time-consuming, which not only affects the continuity of paper card processing and reduces processing efficiency, but may also cause the blade installation position to shift due to improper operation during bolt removal and installation, thus affecting the subsequent slitting accuracy and causing inconvenience to paper card processing.

[0003] A Chinese patent application with publication number CN102862177B discloses a slitting device and a paper product processing machine, including a frame, a power source, a transmission component, a guide shaft, a guide plate, a support roller, and a transfer roller mounted on the frame, as well as a slitting device. An upper cutter is mounted on the guide plate, and a bottom cutter is mounted on the frame. The transfer roller is used to transfer the paper product to the support roller and place the paper web of the paper product on the bottom cutter. The power source drives the guide plate to slide on the guide shaft via the transmission component, thereby driving the shearing wheel of the upper cutter to rotate relative to the bottom cutter, thereby cutting the paper web between the bottom cutter and the upper cutter.

[0004] Although the upper and lower cutting blades of this slitting device are highly durable, requiring no sharpening for at least two years, significantly extending the time needed for sharpening and replacing blades, saving costs and improving efficiency, and the way the upper and lower cutting blades work together eliminates the need for a sharp blade edge, improving operational safety, the slitting device in this patent has a relatively simple structure and limited functionality. For example, the lack of a vacuum adsorption component prevents the adsorption and fixation of paper cards during the slitting process, potentially affecting slitting accuracy and results. Furthermore, the blade replacement method is not as convenient as with quick-release components, hindering equipment maintenance efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a paper card processing slitting device. By combining quick-release components and vacuum adsorption components, it solves the problem that existing paper card processing slitting devices require the removal of multiple bolts when replacing the cutter head, which is cumbersome, time-consuming, affects processing efficiency, and is prone to causing the cutter head to be misaligned.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a slitting device for paper card processing, comprising a worktable, a quick-release assembly, and a vacuum adsorption assembly. A CNC console is located on the left side of the worktable, extending into the inner cavity of the CNC console and having a power mechanism at its top. A vertical plate is fixedly connected to the right side of the worktable, and an air suction head is located at the top of the worktable. The quick-release assembly includes a cutter head, with cutter holders on both sides. A locking mechanism is located at the top of each cutter holder. The left side of each cutter holder is fixedly connected to the power mechanism, and the right side of each cutter holder has a sliding mechanism. The vacuum adsorption assembly includes an air suction mechanism, the bottom of which is fixedly connected to the bottom of the inner cavity of the CNC console. A pipe is located at the right air inlet of the air suction mechanism, extending through the right side of the pipe into the inner cavity of the worktable and communicating with the air suction head.

[0008] The present invention is further configured such that the power mechanism includes a motor, the bottom of which is fixedly connected to the worktable, and a threaded rod is fixedly connected to the output end of the top of the motor. A nut is threadedly connected to the surface of the threaded rod, and the right side of the nut is fixedly connected to a tool holder. An opening that mates with the nut is provided on the left side of the CNC table. The output end of the top of the motor drives the threaded rod to rotate. The threaded rod forms a transmission engagement with the nut through the threads on its surface, converting the rotational motion of the motor into the linear movement of the nut. The right side of the nut is rigidly connected to the tool holder, thereby driving the tool holder to move. The opening on the side wall of the CNC table provides a spatial channel for the movement of the nut, ensuring that the entire transmission process is smooth and interference-free.

[0009] The present invention is further configured such that the locking mechanism includes electric push rods, the rear sides of which are fixedly connected to the tool holders via brackets, and the output ends of the bottom of the two electric push rods are fixedly connected to pins. The bottom of the two tool holders is provided with locking holes that cooperate with the pins, and the sides of the tool head are provided with locking holes that cooperate with the locking mechanism. The output ends of the bottom of the electric push rods drive the pins to move linearly. When locking is required, the pins extend downward and are inserted sequentially into the preset locking holes at the bottom of the tool holders and the corresponding locking holes on both sides of the tool head, thereby firmly locking the tool head onto the tool holders.

[0010] The present invention is further configured such that the sliding mechanism includes a slider, the left side of which is fixedly connected to the tool holder, a sliding rod is slidably connected to the surface of the slider, and the right side of the sliding rod is fixedly connected to the vertical plate. The surface of the slider and the sliding rod form a sliding fit, allowing the slider to move smoothly in a straight line along the sliding rod. The right side of the sliding rod is fixedly connected to the vertical plate, thereby supporting and positioning the entire sliding mechanism on the equipment structure, ultimately ensuring the stability and guiding accuracy of the tool holder during the linear movement process.

[0011] The present invention is further configured such that the suction mechanism includes an air pump, the bottom of which is fixedly connected to the CNC table, the left air inlet of which is connected to a pipe, and the rear air outlet of which is connected to an air outlet pipe. The left air inlet of which is connected to the working area through a pipe is responsible for adsorbing and fixing the paper card, while the rear air outlet of which is connected to the air outlet pipe concentrates and discharges the collected gas, thereby achieving the fixation of the processing area.

[0012] The present invention is further configured such that the rear side of the air outlet pipe penetrates the CNC table, and a dustproof net is provided at the rear air outlet of the air outlet pipe. The rear part of the air outlet pipe penetrates the housing of the CNC table, guiding the airflow inside to the outside. A dustproof net is provided at the air outlet of the rear side of the air outlet pipe, the function of which is to prevent impurities in the external environment from entering the interior of the mechanism through the air outlet, thereby ensuring the cleanliness of the air pump and internal pipelines.

[0013] The present invention is further configured such that the top of the threaded rod is movably connected to the CNC table via a bearing, and a cabinet door is provided at the bottom of the front side of the CNC table. The movable connection between the top of the threaded rod and the top structure of the CNC table via the bearing effectively reduces frictional resistance. The cabinet door at the bottom of the front side of the CNC table facilitates access to the internal storage space of the equipment for the storage and retrieval of tools or parts.

[0014] In summary, this utility model has the following beneficial effects: 1. This utility model, through a quick-release assembly, utilizes symmetrically arranged tool holders on both sides of the cutter head and a locking mechanism on the top to achieve rapid clamping and reliable fixation of the cutter head, effectively improving operational convenience and working stability. The rigid connection between the left side of the tool holder and the power mechanism ensures the continuity of power transmission, while the cooperation of the sliding mechanism on the right side allows the cutter head to move smoothly during assembly and disassembly, reducing operational intensity and avoiding accidental damage to the cutter head. The overall structure is compact and highly coordinated, significantly improving maintenance efficiency and component lifespan.

[0015] 2. This utility model uses a vacuum adsorption component, and the stable connection between the suction mechanism and the bottom of the CNC table cavity ensures the stability of the overall structure. The air inlet on the right side extends to the inner cavity of the worktable through a pipe and connects with the suction head to form a continuous and efficient adsorption path, thereby effectively improving the reliability and continuity of adsorption operations. At the same time, it simplifies the internal structural layout, enhances the convenience of operation and maintenance, and ultimately helps to improve overall work efficiency and extend the service life of the equipment.

[0020] Specifically: The left side of the worktable 1 is equipped with a CNC table 101 for overall control. The worktable 1 runs through the interior of the CNC table 101 and a power mechanism 4 that provides cutting power is installed on the top.

A cabinet door is provided at the bottom of the front side of the CNC table 101.

[0022] Specifically: Motor 41 is a 57 / 86 series hybrid stepper motor, responsible for providing rotational power. Its bottom is fixed on the worktable 1, and its top output end drives the threaded rod 42 to rotate. The threaded rod 42 converts the rotational motion into linear motion through the threaded engagement with the nut 43. The right side of the nut 43 is connected to the tool holder 22, thereby driving the tool holder 22 to move. The CNC table 101 has an opening for the nut 43 to move.

The bottom front side of the CNC table 101 is also equipped with a cabinet door for easy maintenance.

[0023] The implementation principle of this utility model is as follows: During operation, the operator first places the paper card to be cut on the top of the workbench 1. The vacuum adsorption assembly 3 is started through the CNC console 101, and the air pump 311 starts working. Through the pipe 32, it generates an adsorption effect with the suction head 103, firmly adsorbing the paper card onto the surface of the workbench 1 to ensure stability during the cutting process. Subsequently, the motor 41 in the power mechanism 4 drives the threaded rod 42 to rotate, which drives the nut 43 and the connected blade holder 22 to move smoothly along the slide rod 242 of the sliding mechanism 24, thereby adjusting the blade head 21 to the predetermined cutting position. When it is necessary to replace the cutter head 21, the electric push rod 231 of the locking mechanism 23 controlled by the CNC console 101 retracts the pin 232, releasing the fixation of the cutter head 21. The old cutter head 21 can then be removed from between the cutter holders 22. After replacing the new cutter head 21, the electric push rod 231 pushes the pin 232 into the locking holes on both sides of the cutter head 21 to achieve quick locking. During the slitting process, the power mechanism 4 continuously drives the cutter head 21 to move and complete the slitting operation. The vacuum adsorption component 3 always keeps the paper card fixed. After the slitting is completed, the air pump 311 stops working, and the finished product can be removed for subsequent processing.
