Problems solved by technology
The disadvantages of the existing paper cutters are that the cutting edges of paper and cardboard are generally not high in uniformity, and the squareness deviation is large. Automatic positioning adjustment, high operating noise, and can not complete the non-stop automatic stacking function, the production efficiency is relatively low
Existing paper cutters are generally only suitable for production with an annual output of less than 50,000 tons. However, most of the investment projects of large paper mills currently have an annual output of more than 200,000 tons. Simple paper cutters can no longer meet the production scale. requirements
Although the existing high-speed precision paper machines in the world have a high degree of automation and large production capacity, they are expensive in construction and maintenance

Embodiment Construction
[0017] Figure 1 to Figure 5 An embodiment of the invention is shown.
[0018] Such as figure 1 Shown: The high-speed precision paper cutter includes unwinding frame system 1, slitting system 2, cross-cutting system 3, high-speed conveying system 4, stacking system 5, and stacking system 6. The function of the paper stacking system 5 is to smoothly realize the stacking of the front and rear two sheets of paper during the paper conveying process, so as to create conditions for subsequent stacking. The buffer device is an important device in the stacking system 5, which can decelerate the previous stack of paper webs during the paper conveying process, so that the latter stack of paper webs can be superimposed on the previous stack of paper webs.
[0019] Such as figure 2 , image 3 As shown: the buffer device of the high-speed precision paper cutter includes a buffer wheel 101 , a support plate 102 , a beam 103 , a yoke 104 , and a hand wheel device 105 . The buffer wheel...

A high-speed precision paper cutter buffering device comprises a plurality of buffering wheels, a plurality of supporting plates, a beam, a fork arm and a hand wheel device. The supporting plates are fixed onto the beam, each buffering wheel is mounted on an independent supporting plate, the fork arm is connected with the beam in a clamped manner, and the hand wheel device is mounted on a side plate and matched with the fork arm. The buffering device is driven without power and light and simple in structure, each buffering wheel is fixed through an independent supporting sheet, the supporting sheet has excellent elasticity, constant paper articulating pressure in the whole running process can be ensured, the pressure at each point is automatically adjusted in real time, the buffering wheels can be integrally raised or lowered through a hand wheel, the best paper web passing gap is ensured, and a brake wheel can furthest absorb kinetic energy loss generated in the buffering process of a paper web, so that surface friction damage to the paper web can be reduced.
Description
technical field [0001] The invention belongs to papermaking equipment, and relates to a buffer device of a high-speed precision paper cutting machine. Background technique [0002] Paper cutting machines are required for single-layer or multi-layer paper cutting in paper mills. The disadvantages of the existing paper cutters are that the cutting edges of paper and cardboard are generally not high in uniformity, and the squareness deviation is large. Automatic positioning adjustment, the operation noise is relatively large, and the function of automatic pallet change without stopping the machine cannot be completed, and the production efficiency is relatively low. Existing paper cutters are generally only suitable for production with an annual output of less than 50,000 tons. However, most of the investment projects of large paper mills currently have an annual output of more than 200,000 tons. Simple paper cutters can no longer meet the production scale. requirements.
