Miscanthus floridulus stalk gluing device and method

Abstract

The invention discloses a miscanthus floridulus stalk gluing device, which comprises a machine frame, a motor, a speed regulating and transmission mechanism of the motor, a glue pool (1) and upper and down pressing rollers, wherein the at least five pairs of up and down rollers comprise 1 to 2 pairs of longitudinal cutting rollers (4), a pair of pressing rollers (6), 1 to 3 pairs of pressing rollers (7) and one pair of gluing rollers (8) in turn in a material feeding direction; the diameter of each pair of up and down rollers is 80 to 400 millimeters; the two ends of each roller shaft are provided with elastic devices; a feed gap (5) and a material guide plate (3) are arranged between the adjacent roller surfaces of each pair of up and down rollers; the pressing rollers are arranged in an arc shape; the feed gaps (5) of the head pair of rollers (4) and the tail pair of rollers (8) are exposed from a glue liquid level (2); and the feed gaps (5) of the other pairs of rollers are positioned in glue liquid. The gluing of the miscanthus floridulus stalks by using the device are implemented by the steps of: cutting, pressing and glue seeping; repeated pressure applying, pressure relieving and glue spreading; and glue extruding and returning to the glue pool. Compared with the traditional pressurizing gum dipping in a pressure tank, the device eliminates worries for easy explosion, performs glue application and defibering at the same time, has high efficiency and applies glue deeply, widely and uniformly.

Description

technical field [0001] The invention relates to a device for sizing glue in the process of man-made board processing and a gluing method thereof. Background technique [0002] Glue sizing in the production process of wood-based panels is a very important production link. As far as the methods of sizing are concerned, there are dipping, gluing, spraying and pouring, etc., and gluing can be divided into normal pressure gluing and adding Pressure dipping, etc., the pressure dipping of the prior art is carried out in a special pressure tank, the glue and the object to be sized are placed in the pressure tank, the object to be sized is immersed in the glue, and the sealing cover is covered to The tank is pressurized to increase the penetration of the glue into the object to be glued for sizing. This kind of pressurized dipping requires a special pressure vessel, which has potential safety hazards. However, the pressure tank is limited by its volume and cannot be applied in large...

AI Technical Summary

Problems solved by technology

This kind of pressurized dipping requires a special pressure vessel, which has potential safety hazards. However, the pressure tank is limited by its volume and cannot be applied in large quantities at one time. The work efficiency is not high, and the penetration of the glue is not uniform. Re-comb the surface of the glued object

Especially the stems of the five-jointed awns, the stems are more than 2m long and 0.5-1.5cm thick. There should be suitable sizing devices and methods for the stalk sizing of five-jointed awn stems with a biological structure. At present, no relevant reports and real objects have been found through retrieval and market investigation.
