[0002] The paper feeding head is an important component of the paper feeding machine, and its performance directly affects the performance of the paper feeding machine. It is an important part in printing machinery that requires extremely high, and is called the heart of the paper feeding machine. At present, the paper feeding head at home and abroad is composed of six groups of mechanisms, including a rack, a movement, a gas distribution, a paper separating, a paper feeding, and a paper surface height detection mechanism (commonly known as a presser foot mechanism). The mechanism is integrated with machine, electricity and gas. It is not only complex, but also requires precise coordination between the actions of each mechanism. The existing paper separating and feeding mechanism is generally two mechanisms, and multiple cams and power shafts are provided for driving and work cooperatively. The structure is relatively complex, and the efficiency is low. In some paper separating and feeding integrated mechanisms, the control of the movement of the suction nozzle is not a straight line, and the displacement of the paper feeding may have movement interference, the cam and the guide wheel may slide, and the control is not stable. SUMMARY

[0004] The technical problem to be solved by the utility model is to provide a compact paper feeding head paper separating mechanism, which is compact in structure, and the paper feeding and paper separating movement will not interfere, and the control is stable and efficient.

[0005] TECHNICAL SCHEME

[0006] To solve the above problems, the technical scheme provided by the utility model is as follows:

[0007] A compact paper feeding head paper separating mechanism, comprising a fixed shaft, a lifting connecting rod and a horizontal moving connecting rod rotatably connected to the fixed shaft, a guide wheel is arranged on the lifting connecting rod and the horizontal moving connecting rod, a lifting cam and a horizontal moving cam are arranged in cooperation with the guide wheels, the lifting cam and the horizontal moving cam are fixedly connected to a power shaft, the lifting connecting rod is provided with a bent section and a straight section extending out of the bent section, the straight section passes through a through hole of a lifting sliding seat and is slidably connected through a moving guide wheel, the lifting sliding seat is connected to a suction nozzle assembly, the lifting sliding seat is slidably connected with a lifting straight guide rod, the lifting straight guide rod is fixedly connected to a horizontal moving seat, and the horizontal moving seat is connected to the horizontal moving connecting rod and is limitingly and slidably arranged in a horizontal moving fixed seat.

[0008] The whole paper separating mechanism is designed very compactly, and is suitable for printing equipment with limited space.

[0009] The lifting connecting rod is responsible for the vertical movement of the suction nozzle assembly, so that the suction nozzle can accurately contact the paper on the top of the paper stack.

[0010] The horizontal movement of the suction nozzle assembly is controlled by the horizontal link to smoothly deliver the separated paper to the next process.

[0011] The lifting cam and the horizontal cam are fixed on the power shaft, and the corresponding link is driven to move linearly or in an arc by rotation.

[0012] The guide wheels are installed on the link and roll along the cam surface to achieve precise guidance and position control of the link.

[0013] The lifting slide connects the suction nozzle assembly and slides along the lifting linear guide through the straight section and the moving guide wheel, ensuring smooth movement of the suction nozzle in the vertical direction.

[0014] The horizontal seat is limited to slide in the horizontal fixed seat, providing stable support and guidance for the suction nozzle assembly in the horizontal direction.

[0015] Non-interference motion: through reasonable mechanical layout, it ensures that there is no mutual interference between the paper delivery and the paper separation motion, thereby improving the stability and efficiency of the system.

[0016] Stable and efficient: due to the use of precise cam-guide wheel system and limited sliding structure, the mechanism can provide stable paper separation and paper delivery action, meeting the needs of high-speed printing.

[0017] As an option, the suction nozzle assembly includes a suction nozzle and a suction nozzle seat, the suction nozzle is installed on the suction nozzle seat, and the suction nozzle seat is fixed to the lifting slide through the gusset.

[0018] The suction nozzle is the key component that directly contacts the paper and uses vacuum force to adsorb the topmost paper. The suction nozzle seat is the mounting base of the suction nozzle, responsible for fixing the suction nozzle and providing the necessary channel to connect the vacuum source. The gusset is used to firmly connect the suction nozzle seat to the lifting slide, ensuring that the suction nozzle assembly remains stable during vertical movement. The lifting slide guides the suction nozzle assembly for smooth movement in the vertical direction through the linear guide, ensuring that the suction nozzle can accurately reach the top of the paper stack and complete the paper separation action. The lifting slide slides along the lifting linear guide through the straight section and the moving guide wheel, ensuring accurate control of the suction nozzle assembly in the vertical direction.

[0019] As an option, the horizontal seat and the lifting slide are symmetrical structures on both sides.

[0020] The horizontal seat and the lifting slide adopt a symmetrical structure design on both sides, enhancing the overall stability of the mechanism,

[0021] As an option, the horizontal seat and the lifting slide are centrally provided with a long slot for accommodating the gusset.

[0022] The main function of the long slot is to provide a fixed accommodation space for the gusset, optimizing the functionality and assembly convenience of the compact paper delivery head paper separation mechanism.

[0023] As an option, the horizontal movement fixed seat and the lifting slide are equipped with linear bearings.

[0024] Linear bearings provide high-precision guidance, ensuring the precise movement of the suction nozzle assembly in both vertical and horizontal directions, which is crucial for the accurate separation and delivery of paper.

[0025] Long service life: Due to the small friction, the wear rate of linear bearings is slow, prolonging the service life of mechanical components and reducing the frequency of maintenance. The rolling friction of linear bearings produces less noise, helping to reduce the operating noise of the entire device and providing a quieter working environment.

[0026] As an option, the horizontal movement connecting rod is connected with a tension spring, the other end of the tension spring is fixed, and the tension direction of the tension spring is towards the horizontal movement cam.

[0027] The main function of the tension spring is to quickly pull the horizontal movement connecting rod back to the initial position after the horizontal movement cam rotates. This reset mechanism ensures that the suction nozzle assembly can quickly return to the position ready for the next paper delivery after each paper delivery action is completed, improving the response speed of the system. The tension spring can provide a certain buffering effect during the movement of the horizontal movement connecting rod, reducing impact and vibration, thereby improving the smoothness and stability of the entire system. The tension of the tension spring can assist the horizontal movement cam in driving the horizontal movement connecting rod, especially during the process of the cam rotating from the high point to the low point. The tension of the tension spring can help overcome friction and other resistance, making the movement of the horizontal movement connecting rod smoother.

[0028] As an option, the lifting connecting rod is located above the lifting cam.

[0029] The gravity of the lifting connecting rod and the force of the moving guide wheel on the lifting connecting rod together serve as the driving force for the reset of the lifting connecting rod.

[0030] As an option, the fixed shaft is fixed at both ends to two side plates, and all components are installed between the two side plates.

[0031] Ensures the overall structural stability and compactness of the compact paper feed head separating mechanism. By concentrating all moving parts and support structures between the two side plates, not only does it improve the integration of the system, but also enhances the rigidity and reliability of the mechanism. The two side plates serve as the main support frame of the entire paper feed head separating mechanism, providing a solid foundation to ensure that all moving parts work stably.
