Problems solved by technology

[0007] 1. Both sides of the rubberizing roller expand greatly, resulting in contact between the rubberizing roller and the lower roller. Since the wear resistance of the corrugated roller is much greater than that of the rubberizing roller, it will cause the rubberizing roller to be worn, and the texture on the surface of the rubberizing roller will be changed. Wear off, when producing larger widths, the phenomenon of poor gluing or no glue on the worn parts will cause the cardboard to be unusable and forced to replace the gluing roller
[0008] 2. Long-term wear will also wear off the surface coating of the corrugated roller, resulting in poor corrugated roller shape, and the corrugated roller is forced to be replaced
[0009] 3. If the temperature is too high, the glue in the glue tray is easy to thicken, which leads to frequent replacement of glue

Embodiment Construction

[0020] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0021] Such as figure 2 A new type of single-sided machine gluing roller shown includes a hollow cylinder 4 and a shaft head 1 fixed and sealed with both ends of the cylinder 4. The cylinder 4 and the shaft head 1 are formed by heat sleeve welding. An annular groove is arranged on the outer end surface of the shaft head, and 4 to 8 liquid injection holes 8 are evenly distributed in the groove. One of these liquid injection holes 8 is provided with a nozzle 2 and communicates with the outside, and the rest are injected The liquid hole is sealed with the end face of the head 7, and the position of the liquid injection port on the shaft head 1 at both ends of the cylinder body 4 corresponds to the position of the liquid injection port connected to...

Abstract

The invention discloses a novel single facer glue spreading roller. The novel single facer glue spreading roller comprises a hollowed cylinder, and shaft heads fixedly and tightly connected with the two ends of the cylinder, wherein the cylinder and the shaft heads are connected through shrink-fitting and welding; annular grooves are formed in the outer end surfaces of the shaft heads; liquid injecting holes are evenly distributed in the grooves; a closed hollow liner is arranged in the cylinder; the two ends of the liner are fixedly connected with the inner wall of the cylinder through annular pipe plates; inner rings of the annular pipe plates are arranged around the liner, and are fixedly welded with the surface of the liner; through holes are evenly distributed in the circular surfaces of the annular pipe plates; the length and the end surface diameter of the liner are both smaller than the length and the end surface diameter of the cylinder; and a liquid injecting space is formed between the outer wall of the liner and the inner wall of the cylinder. The novel single facer glue spreading roller has the following beneficial effects: (1) the surface temperature of the glue spreading roller is uniform to reduce the friction with a corrugated roller; (2) the service lives of the corrugated roller and the gluing roller are prolonged; the spread of glue is uniform; and the paperboard quality is high; and (3) the replacement frequency of glue in a glue tray is largely reduced, so that the cost is decreased.

Description

technical field [0001] The invention relates to the field of corrugated cardboard production equipment, in particular to a novel rubber coating roller for a single-sided machine. Background technique [0002] The general structure of corrugated cardboard single-sided machine is composed of paper guide roller, preheating roller, upper and lower corrugating rollers, pressure roller, pressurized cylinder, lower preheating roller, lower preheating roller, forming compound device and including rubber coating roller and rubber leveling roller. , Pulp plate and other gluing mechanisms. The corrugated base paper adjusts its tension through the paper guide roller, and the upper preheating roller controls the humidity. It slides over the top of the upper corrugating roller and enters the corrugated channel between the heated upper and lower corrugating rollers. It is pressed and ironed at the meshing point on the center line of the two rollers. After ironing and forming, it will run ...
