Abstract

The utility model discloses a pressure maintaining roll type continuous roller press, which comprises a home roll, a driving roll, a thickness setting roll, a secondary pressing roll, a primary pressing roll and a deviation adjusting roll. A steel strip is sequentially wound on the rolls to form a circulating pressure mechanism, three pressure maintaining rolls are evenly arranged between the primary pressing roll and the secondary pressing roll and form a rolling pressure pair with the home roll to prolong the time period of pressing on plate blanks and to continuously press the plate blanks, and three pressure maintaining rolls are evenly arranged between the thickness setting roll and the driving roll and form a rolling pressure pair with the home roll to press the plate blanks and to prolong the time period of pressing on the plate blanks. Continuity of pressure for the plate blanks is greatly improved, glue is solidified at a high temperature and at a high pressure, the internal bonding strength, the static bending hardness and the surface bonding strength of finished density boards or shaving boards are greatly improved, and density is well controlled.

Description

Pressurize roll-type continuous calendar press

Technical field

The utility model relates to the improvement to existing wood-based plate roll squeezer structure; A kind of pressurize roll-type continuous calendar press is specifically disclosed; Be used in the serial rolling production line of wood-based plate industry; Suppress the equipment of the hot-forming workshop section of slim density board or particieboard, belong to the Wood-based Panel Production mechanical equipment technical field.

Background technology

The main effect of wood-based plate roll squeezer is that high pressure and high-temperature are acted on the slab that is mixed with glue, makes its glue curing, lets loose slab become the sheet material with certain density, intensity, hardness.Most critical is the temperature and pressure parameter in whole roll-in process, and traditional roll squeezer has only 6 rollers, wherein has only 3 rollers that slab is pressurizeed; Once pressurization, secondary pressurize and decide thickness pressurization three phases, because the structure of this roll squeezer is limit, pressure can not act on the slab all the time; Slab is pressurized continuously, will cause the intensity of production board to descend, for improving the intensity of sheet material; Have only the use amount that increases pressure and glue, thereby cost increases the efficient reduction.

Summary of the invention

The utility model discloses a kind of pressurize roll-type continuous calendar press; Setting up a plurality of pressurize rollers pressurizes on slab continuously; Guarantee that slab is from getting into press to leaving press; All the time the effect that is under pressure, the pressure that solves existing wood-based plate roll squeezer existence is discontinuous, influences the problem of Wood-based Panel Production quality.

The technical solution of the utility model is following: device has home roll, driven roller, thickness measuring roller, secondary backer roll, backer roll, regulating roller on the frame of roll squeezer, and steel band is wrapped in proper order and constitutes circulating pressure mechanism on each roller; Wherein, Backer roll, secondary backer roll and a thickness measuring roller lay respectively at once pressurization, the secondary pressurization of roll squeezer and decide thickness three zones of pressurizeing slab is pressurizeed; It is characterized in that: between backer roll and secondary backer roll, evenly being provided with 3 pressurize rollers and home roll, to constitute rolling pressure secondary; Improve the time cycle of slab pressurized, continuously slab is pressurizeed; Between thickness measuring roller and driven roller, evenly be provided with 3 pressurize rollers and home roll formation rolling pressure pair slab is pressurizeed, improve the time cycle of slab pressurized.

The good effect of the utility model is: pressurizeing and decide thickness pressurised zone and thickness measuring roller and main drive roll zone at once pressurization, secondary respectively increases the pressurize roller quantity to the slab pressurization; Improved continuity greatly to slab pressure; Let the solidification process of glue under high temperature, high pressure, carry out; Make the internal bond strength of finished product density plate or particieboard, quiet bent hardness, table bond strength all improve greatly, the control of density is well controlled.

Description of drawings:

Fig. 1 is the utility model structure principle chart;

Among the figure: 1, home roll; 2, driven roller; 3, thickness measuring roller; 4, steel band; 5, regulating roller; 6, backer roll; 7, secondary backer roll; 8, pressurize roller; 9, pressurize roller; 10, pressurize roller; 11, slab; 12, pressurize roller; 13, pressurize roller; 14, pressurize roller.

The specific embodiment:

As shown in Figure 1, device has home roll 1, driven roller 2, thickness measuring roller 3, secondary backer roll 7, backer roll 6, regulating roller 5 on the frame of roll squeezer, and steel band 4 orders are wrapped in and constitute circulating pressure mechanism on each roller; Wherein, Backer roll 6, secondary backer roll 7 and a thickness measuring roller 3 lay respectively at once pressurization, the secondary pressurization of roll squeezer and decide thickness three zones of pressurizeing slab 11 is pressurizeed; Wherein: between backer roll 6 of roll squeezer and secondary backer roll 7, increase by 3 pressurize rollers 12, thickness measuring roller 13, thickness measuring roller 14; Improve the time cycle of slab 11 pressurizeds, continuously to slab 11 pressurizations; After slab 11 leaves thickness measuring roller 3, between thickness measuring roller 3 and driven roller 2, increase by 3 pressurize rollers 8,

thickness measuring roller

9,11 pressurizations of 10 pairs of slabs of thickness measuring roller again, the time cycle of improving slab 11 pressurizeds.

Claims

1. pressurize roll-type continuous calendar press, device has home roll, driven roller, thickness measuring roller, secondary backer roll, backer roll, regulating roller on the frame of roll squeezer, and steel band is wrapped in proper order and constitutes circulating pressure mechanism on each roller; Wherein, Backer roll, secondary backer roll and a thickness measuring roller lay respectively at once pressurization, the secondary pressurization of roll squeezer and decide thickness three zones of pressurizeing slab is pressurizeed; It is characterized in that: between backer roll and secondary backer roll, evenly being provided with 3 pressurize rollers and home roll, to constitute rolling pressure secondary, continuously slab pressurizeed; Between thickness measuring roller and driven roller, evenly be provided with 3 pressurize rollers and home roll formation rolling pressure pair slab is pressurizeed, improve the time cycle of slab pressurized.
