Description

Technical Field

[0001] The utility model relates to an improved invention of a cross-cutting mechanism, in particular to a core plate cross-cutting mechanism of honeycomb core processing equipment. Background Art

[0002] The core board is made of multiple core papers. The core board is sent to the cross-cutting station. The cross-cutting mechanism cross-cuts the core board into core strips, and the core strips are composited and compacted to form a continuous honeycomb core. The cutter of the core board cross-cutting mechanism is driven by the crank slider mechanism to lift and lower for cross-cutting operations. The linear guide of the crank slider mechanism slides with the knife seat. The crank moves at high speed and requires lubrication and cooling. The crank is immersed in the oil tank, and the crank is connected to the knife seat through the piston rod, and the piston rod is sealed relative to the oil tank. When the crank moves at high speed, the piston rod will be deformed by force. Even a slight deformation will cause a gap between the piston rod and the oil tank, resulting in oil leakage; and the force of the piston rod is transmitted to the linear guide, resulting in large force on the linear guide and a short service life. Summary of the invention

[0003] In view of the technical problems existing in the background technology, the technical problem solved by the utility model is to provide a core plate cross-cutting mechanism with stable cutting and long service life.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solution: the core plate cross-cutting mechanism is characterized in that it includes:

[0005] A frame having a first guide rail;

[0006] A fuel tank, which is mounted on the frame;

[0007] A knife seat, which is slidably arranged on the first guide rail;

[0008] And a transmission component, which includes a crank and a piston rod arranged in an oil tank, one end of the crank is rotatably connected to the motor through an eccentric wheel, the other end of the crank is rotatably connected to one end of the piston rod, the other end of the piston rod passes through the oil tank and is connected to the tool holder, the piston rod is slidably arranged on a second guide rail, and the first guide rail is parallel to or on the same straight line as the second guide rail.

[0009] The knife seat and the piston rod of the utility model are respectively equipped with a first guide rail and a second guide rail. When the crank moves at high speed, the second guide rail shares the force applied to the first guide rail, and the second guide rail directly guides the piston rod to avoid deformation of the piston rod due to force, so that the piston rod keeps moving in a straight line and remains sealed with the oil tank.

[0010] Preferably, the knife holder is composed of a plurality of unit knife holders, one unit knife holder is equipped with at least two first guide rails evenly distributed on the left and right sides, and the piston rod is connected to the middle position of the unit knife holder. During high-speed movement, no deviation occurs, the service life of each component is longer, and the cutting is more stable.

[0011] Preferably, the second guide rail is a guide hole, and the piston rod is a piston shaft matching the guide hole. The piston shaft moves in the guide hole, and the guide hole not only guides the piston shaft, but also increases the strength of the piston rod, further preventing its deformation.

[0016] The following describes the relevant details and working principles of the implementation and examples of the utility model in conjunction with the accompanying drawings. This core plate cross-cutting mechanism includes a frame, an oil tank 3, a knife seat 7 and a transmission component, the frame is provided with a first guide rail 6; the oil tank 3 is installed on the frame; the knife seat 7 is slidably arranged on the first guide rail 6, and a cutter is installed on the knife seat 7; the transmission component includes a crank 2 and a piston rod 5 arranged in the oil tank, one end of the crank 2 is rotatably connected to the motor through an eccentric wheel 1, the other end of the crank 2 is rotatably connected to one end of the piston rod 5, and the other end of the piston rod passes through the oil tank 3 and is connected to the knife seat 7, a seal is provided between the piston rod 5 and the oil tank, so that the piston rod moves relative to the oil tank 3 in a sealed manner to avoid leakage of lubricating oil in the oil tank, and the piston rod 5 is slidably arranged on the second guide rail 4, and the first guide rail 6 is parallel to or on the same straight line as the second guide rail 4. The motor drives the eccentric wheel 1 to rotate, and one end of the crank 2 rotates with the eccentric wheel. The other end of the crank drives the piston rod 5 to move back and forth linearly along the second guide rail 4. The piston rod drives the knife seat 7 to move back and forth linearly on the first guide rail 6. The crank 2 converts the rotational motion of the eccentric wheel into the linear motion of the piston rod, so that the cutter moves back and forth linearly to perform cross-cutting operations. The knife holder 7 and piston rod 5 of the utility model are respectively equipped with a first guide rail 6 and a second guide rail 4, wherein the first guide rail 6 adopts a linear guide rail, and the second guide rail 4 adopts a guide hole. The piston rod 5 is a piston shaft matched with the guide hole, and the piston shaft moves in the guide hole. The guide hole not only guides the piston shaft, but also increases the strength of the piston rod and prevents its deformation. During the high-speed movement of the crank, the second guide rail 4 shares the force received by the first guide rail 6, so that the first guide rail is less damaged and has a long service life. In addition, the second guide rail 4 directly guides the piston rod, increases the strength of the piston rod, avoids the piston rod from being deformed by force, keeps the piston rod moving in a straight line, and keeps it sealed with the oil tank to avoid oil leakage. The knife holder is composed of a number of unit knife holders, and a unit knife holder is equipped with at least two first guide rails and evenly distributed on the left and right. The piston rod is connected to the middle position of the unit knife holder, supported on the left and right and balanced on the left and right, which increases the stability of high-speed movement, and each component has a longer service life and a higher and more stable cutting.
