Surface paper edge grinding machine for seamless paper tubes

Abstract

The invention discloses a surface paper edge grinding machine for seamless paper tubes. The surface paper edge grinding machine comprises a paper laying table, a suction disc and a horizontal edge grinding knife rest, wherein the two opposite ends of the edge grinding knife rest are provided with upper and lower parallel inclined grinding knives; a passage is formed over the suction disc, and the suction disc is suspended below the passage; a hanger rod is arranged just above the suction disc; the top of the hanger rod is arranged in the passage through a roller; an air tube is arranged in the center of the suction disc and is laid along the hanger rod; the other end of the air tube is communicated with an air faucet of an air tank; the air faucet of the air tank is provided with an automatic control valve; the automatic control valve controls the air tank to exhaust or suck air; the upper surface of the edge grinding knife rest is provided with a plane table with adjustable length; the grinding surface of each grinding knife has a gradient; and the upper grinding knife is arranged on a gear lifter. According to the surface paper edge grinding machine, paper is sucked or laid down by the suction disc, a group of opposite edges of the paper are ground to have certain gradients through the grinding knives, and the paper edges with the gradients are rolled on the surface of one paper tube and are just butted with each other, therefore, the bonding area of the paper edges is enlarged, and the edges are prevented from warping.

Description

technical field

[0001] The invention relates to a paper edging machine for the surface layer of a seamless paper tube, which is a device for grinding the two paper edges of a seamless paper tube into a meshing gradient, and belongs to the field of machinery. Background technique

[0002] The seamless paper tube has very strict requirements on the joints of the surface paper, which needs to be polished smooth and smooth, and the connection is tight, and no joints can be seen. In the case of very strict requirements, the butt edges of the surface paper of the paper tube must be spliced ​​together without overlapping and without gaps. At the same time, the glue bonding area at the seam must be increased to make the seam tightly bonded to avoid During use, the seams warped or cracked. The surface paper of the traditional paper tube is cut vertically, and then bent and pasted on the surface of the paper tube. For such a seamless paper tube, the upper edge is bonded at the bondin...
