Description

A mechanical blank assembly device for side-pressed bamboo laminated timber infinitely long laminates

technical field

The invention relates to a mechanical blank assembly device of a side-pressed bamboo lamella infinite-length laminate, in particular to a mechanical blank-assembly device of a side-pressed bamboo laminate infinite-length laminate using a step pushing mechanism and a lateral pulling mechanism The device has a simple and high-efficiency structure, and is suitable for use in the blank assembly section of a hot-pressing production line for producing infinite-length side-pressed bamboo laminates.

Background technique

Bamboo glulam is a profile (plate or square) that is glued by long bamboo sheets (generally rectangular in cross section, 1 m-2.5 m in length, about 20 mm in width (or height) and about 6 mm in thickness) . Among them, the thin bamboo lamella is only made up of one layer of bamboo slices glued on the side; while the thick bamboo lamella is made of multiple layers of bamboo laminates glued on the sides and glued together on the front. Therefore, bamboo glulam laminates (bamboo laminates for short) are bamboo jigsaw panels formed by gluing a layer of long bamboo slices on the sides. The narrow side (thickness) and wide side (width) of the rectangular bamboo strips can be used as the glued surface. The bamboo laminate with the wide surface of the bamboo slices as the glued surface is thicker, and has better bonding strength and mechanical properties. It is used as a laminate of bamboo glulam for structure. Since the hot-pressing plate of the hot-pressing machine for producing bamboo lamella laminates is placed horizontally, the gluing surface of the bamboo sheet is in the vertical plane, and the rectangular bamboo sheet with the wide side as the gluing surface is in an upright state; the bamboo laminate is in a vertical state. The gluing surface is on the side of the hot press, that is, the main gluing pressure direction of the bamboo laminate is on the side of the hot press. The bamboo laminate produced in this way is called a side-pressed bamboo laminate.

At present, the assembling of the known side-pressed bamboo lamella laminates (the unit bamboo sheets of which are in a side-standing state) is basically still done by hand. CN109093789A The invention patent of "a side-pressing type bamboo laminated board mechanical blanking device" solves the problem of mechanical blanking of bamboo laminates from bamboo sheets of normal length, but if the production of long or infinite bamboo laminates , Due to the limited length of the bamboo pieces, it needs to be lengthened (and the joints of the adjacent bamboo pieces need to be staggered by a certain distance). However, the bamboo sheets are long and easy to bend, and they are easy to be dislocated and difficult to be aligned when docking. Therefore, it is difficult to realize mechanical automation of the assembly of infinitely long bamboo laminates. At present, the assembly of infinitely long bamboo laminates all rely on manual operations. Due to the thinness of the bamboo pieces, the large number of them, and the coating of adhesives, it is very inconvenient to manually assemble the blanks, which are dirty and tiring, and the efficiency is very low.

The side-standing bamboo pieces are easy to bend and dislocate, and it is difficult to be centered and lengthened. However, if the position of the free end of the bamboo pieces can be controlled to ensure that they are not offside, the following specification bamboo pieces can be moved and connected smoothly. If there is a device that can control the position of the free end of the long-sized bamboo pieces, so that the back bamboo pieces can enter smoothly, the assembly of the infinite-length laminates of the side-pressed bamboo glulam can be mechanized, thereby reducing the labor intensity and improving the work efficiency. Efficiency, will be welcomed by side-pressed bamboo glulam manufacturers.

The position of each push rod 31 in this row of the push rod group of the specification bamboo sheet 5 corresponds to the shortest formwork bamboo sheet 412 of the bamboo sheet group in the stepped formwork 4 respectively, and the spacing of the two adjacent rows of push rod groups is the same as that in the stepped formwork 4.
