The paper feeding device comprises a Y-shaped paper feeding pipe 1, an air supply pipe 2, an air inlet 3, a conical pipe 4 and a conical paper outlet pipe 5, and is characterized by also comprising a Y-shaped paper feeding pipe 1 inserted into the air supply pipe 2 to the rear end of the conical pipe 4, wherein the axis of the Y-shaped paper feeding pipe 1 is superposed with the axis of the air supply pipe 2; the diameter of the front end of the conical tube 4 is larger than that of the tail end; the diameter of the front end of the conical paper outlet pipe 5 is smaller than that of the tail end; the blast pipe 2, the conical pipe 4 and the conical paper outlet pipe 5 are connected in sequence; the air supply pipe 2 is provided with air inlets 3, each air inlet 3 and the air supply pipe 2 form the same angle in the axial direction, the angle range is 30-60 degrees, and the number of the air inlets 3 is 4-20. The paper edge hanging device is simple in structure, reasonable in design and convenient to install and maintain, and solves the problem of paper edge hanging and blocking of the paper edge fan.
Description
Technical Field
The invention belongs to the field of papermaking equipment, and particularly relates to a spiral air paper edge fan device.
Background
In the paper making industry, paper rolls produced by a paper machine can be cut into products with different specifications during rewinding, trimming work of the edge parts of the paper rolls is omitted in the process, if the width of the edge part waste edge is large, the edge part can be used for processing paper cakes, if the width of the edge part waste edge is narrow, the paper edges can be led out only through a paper edge fan to be used for broken paper processing, the traditional paper edge fan is provided with a paper edge fan with cutter teeth, the paper edges can be cut into small sections and then blown out, the problem that the outlet pipe joints of the fan are easy to block after burrs exist is solved, however, the cutter teeth of the fan are easy to damage in the using process, the maintenance cost is increased, the small sections of paper edges are difficult to collect, and a paper edge collecting device is required to be added; the patent "201520039239. X a rewinding machine paper limit collection device" the paper limit fan that relates to is for not taking the straight fan of sword tooth, and this paper limit fan passes through the negative pressure that produces when different pipe diameters of air current flow through and takes out the paper limit, and this kind of fan is convenient for maintain, blows off the paper limit for the whole strip, and the paper limit of being convenient for is collected, but if the air outlet of this kind of fan is slightly burr in the use, the paper limit easily hangs and causes the jam on the burr, makes the paper limit fan air-out unsmooth and can not fine use.
Disclosure of Invention
The utility model provides a spiral fan paper limit fan device which characterized in that: the paper feeding device comprises a Y-shaped paper feeding pipe 1, an air supply pipe 2, an air inlet 3, a conical pipe 4 and a conical paper outlet pipe 5, and is characterized by also comprising a Y-shaped paper feeding pipe 1 inserted into the air supply pipe 2 to the rear end of the conical pipe 4, wherein the axis of the Y-shaped paper feeding pipe 1 is superposed with the axis of the air supply pipe 2; the diameter of the front end of the conical tube 4 is larger than that of the tail end; the diameter of the front end of the conical paper outlet pipe 5 is smaller than that of the tail end; the blast pipe 2, the conical pipe 4 and the conical paper outlet pipe 5 are connected in sequence; the air supply pipe 2 is provided with air inlets 3, each air inlet 3 and the air supply pipe 2 form the same angle in the axial direction, the angle range is 30-60 degrees, and the number of the air inlets 3 is 4-20.
When the device is used, the Y-shaped paper feed pipe can enable the paper edges of the working surface and the transmission surface to enter the paper edge fan together; the paper edge is sucked into the Y-shaped paper feeding pipe and sent out through the paper feeding pipe by utilizing high-speed airflow generated by the fan and negative pressure generated by changing the pipe diameter of the conical pipe; on the basis of the traditional straight-through type paper edge fan, the air inlet mode of the paper edge fan is changed, so that straight air is changed into spiral air, the probability of blockage of the paper edge fan due to burrs is greatly reduced, the efficiency of the paper edge fan is improved, and the maintenance cost of the paper edge fan is reduced; the conical paper outlet pipe enlarges the paper outlet channel and reduces the probability of blockage.
The paper edge hanging device is simple in structure, reasonable in design and convenient to install and maintain, is applied to paper edge collection, and can remarkably improve the problem of paper edge hanging and blocking of the paper edge fan.
