Description
TECHNICAL FIELD
[0001] The utility model relates to hardboard processing technical field especially relates to a cutting machine paper kicking department middle fulcrum adjusting device. BACKGROUND
[0002] Paperboard cutting equipment or other equipment needs to send the stacked paperboard from the bottom one by one, and needs to use a paper kicking mechanism: that is, the bottom layer of the stacked paperboard is pushed out one by one to the next process mechanism through a narrow gap. The traditional paper kicking mechanism usually adopts a crank rocker mode (eccentric wheel drives linear guide rail to make linear reciprocating motion), and length adjusting mechanism needs to be added to the linear reciprocating slider due to different paperboard length requirements.
[0003] However, the current length adjusting mechanism is relatively heavy, and the reciprocating inertia is large, which limits the reciprocating speed of the equipment, increases the vibration of the equipment, and the length adjusting mechanism is only manually locked by a simple screw nut, which cannot be adjusted by electric or servo numerical control. High-speed reciprocating motion causes impact load on the motor and increases the inertia, which is more unreasonable, and the length position cannot be dynamically adjusted during operation, and can only be manually adjusted by screw nut after stopping.
[0004] Therefore, the present application provides a cutting machine paper kicking department middle fulcrum adjusting device to solve the above problems. CONTENT OF THE UTILITY MODEL
[0005] The utility model aims at solving the shortcomings in the prior art and provides a cutting machine paper kicking department middle fulcrum adjusting device.

[0007] A cutting machine paper kicking department middle fulcrum adjusting device, comprising a paper kicking main machine, a second motor is installed in the paper kicking main machine, and the output of the second motor is connected with a motor eccentric swing sleeve, the motor eccentric swing sleeve is connected with a motor swing lever at one end through an eccentric swing lever pin, and the other end of the motor swing lever is hinged with a rocker arm, one end of the rocker arm is connected with a sliding block through a swing main shaft, and a compression spring is welded on the surface of the sliding block, and the compression spring is sleeved on the surface of a stroke adjusting mechanism.
[0008] Preferably, the other end of the rocker arm is hinged with a paper kicking push rod, the paper kicking push rod is connected with the inner wall of the paper kicking main machine through a linear guide rail, and a paper kicking head is installed above the end of the paper kicking push rod away from the rocker arm.
[0009] Preferably, a strip-shaped through groove matched with the paper kicking head is formed in the upper surface of the paper kicking main machine.
[0010] Preferably, an adjusting sliding groove is formed in the side surface of the paper kicking main machine, and a sliding block is slidably connected with the inner wall of the adjusting sliding groove.
[0011] Preferably, the stroke adjustment mechanism includes a mounting frame, which is fixedly located inside the lower part of the paper kicking unit. A first motor is mounted on the surface of the mounting frame, and the end of the first motor is connected to a worm gear via a synchronous belt. The worm gear meshes with the surface of a worm wheel, and an adjusting stud is inserted into the internal thread of the worm wheel.
[0012] Preferably, the worm gear is mounted on the surface of the fixed block via a bearing, and the fixed block has a through hole inside.
[0013] Preferably, the adjusting stud is connected to the slider via a bearing, and a disc is sleeved on the end surface of the adjusting stud near the slider via a bearing. One end of the compression spring is welded to the disc, and the other end of the compression spring is welded to the surface of the fixed block.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] The device maintains a stationary state by adjusting the slide, slider, pressure spring, and stroke adjustment mechanism during the operation of the paper ejector unit, and there are no other adjustment accessories on the paper ejector head. This significantly reduces the weight and minimizes the reciprocating motion inertia, thereby increasing the reciprocating motion speed and production efficiency. At the same time, the stroke adjustment mechanism, using electric or servo CNC, eliminates the need for manual adjustment of the screw and nut, and allows for dynamic adjustment of the length position without stopping the machine, making it convenient and quick.
