The paper cutter is the standard supporting mechanical equipment of the printing factory, which is mainly used to deal with the paper cutting requirements in the pre-printing and post-printing stages. The paper cutter has developed from the original mechanical paper cutter to the tape control room paper cutter, and then to the microcomputer program control, color display, full image operation guidance visual processing and computer-aided cutting. External programming and editing of production data cutting The system makes the paper cutter shorter production preparation time, higher cutting accuracy, lower labor intensity, and better operational safety.

In the screw conveyors used in metallurgy, mining, chemical and other industries, the shaft end gland is widely used for packing sealing. Since the particle size of pulverized coal is 200 mesh, it belongs to fine powder and has certain fluidity. Therefore, due to the poor sealing of the shaft end of

According to the different wire structure of papermaking pulping equipment, papermaking and pulping equipment can be divided into: Fourdrinier wire type, rotary wire type, sandwich wire type, stacked wire type and facing rolls. Paper pulping equipment can be regarded as a linkage composed of multiple equipments. Usually it can be divided into two parts: wet part and dry part. The wet end includes the stock flow equipment, the wire section and the press section; the dry end includes the dryer section, calenders and reels.

The composition of papermaking waste residue is complex. To realize resource recovery, it must be sorted and removed. However, the amount of slag is large and the sorting is difficult. The original equipment on the market only uses the traditional washing and rinsing method to sort out a small part of the recycled granulation. The rest of the burial method is used badly, which brings pollution hazards to the soil and harms future generations.

The pressure screen is widely used in the papermaking industry and is one of the important equipments in the papermaking machinery​. It is a new type of recycled pulp screening equipment, a new generation of recycled pulp processing products. In order to produce better products and improve productivity, we must strictly follow the relevant operating procedures and precautions of the pressure screen. So what should be paid attention to when operating it?

What is the reason why the paper cutter platen does not return? 1. Electrical failure, there are usually 2~3 travel switches behind the paper cutter transmission mechanism (turbine box, gear transmission, etc.) Automatically return to the high point (both for the cutter counting function); the ot
