The need for glued beams is constantly increasing. The use of this material for the construction of private houses allows you to create high-quality elements, as well as use the texture of wood in the interior of the room.
At the same time, the construction of logs began to lose its popularity. Therefore, in our time it is quite profitable to engage in the manufacture of glued beams. This business is really profitable. What equipment is needed for the production of glued beams? And how is its manufacture? We will try to find answers to these and other questions.
The main stages of production
The manufacture of glued beams is a complex process, which consists of several stages.
- First of all, a two-edged beam is obtained from a log. For this, a band saw is used.
- Dissolution of the beam on the edged material.
- Drying of raw materials.
- Roughing. For this, a four-sided planing machine is used.
- The rejection of timber. To select high-quality material, a trimming machine or scanner is used.
- Making mini spikes. In work a tenoning machine is used.
- Spikes are coated with glue, and the workpiece is sent to a special press.
- Glue polymerization at the joints of the lamella.
- Gluing along the height and width of the lamellas, from which the glued beam is obtained.
- Shaping on a four side planer.
The technology for the production of glued beams includes the use of a large amount of equipment, which determines the quality of the final product, as well as the profitability of the enterprise.
Equipment selection
When buying equipment, you need to determine in advance the technological chain of your production. In the event that you will independently harvest wood for production, the presence of your sawmill will be a prerequisite. In addition, it is also worth buying drying chambers and a multi-saw machine.
But some use a short manufacturing cycle to save on expensive equipment. The line for the production of glued beams in this case includes only machines that are directly involved in the manufacture of glued structures from finished raw materials.
The main equipment is converter dryers, trimming machines, vertical hydraulic presses and more. The rules for choosing it differ for different types of devices, so we will analyze each of them separately.
Applicator
The machine that applies glue to wooden structures is equipped with either a bulk-type mechanism or special rollers. A machine that is equipped with an applicator roll costs significantly less. However, in the production of timber, its effectiveness is low. The fact is that it is very important that the glue for the production of glued beams is applied qualitatively.
Therefore, in the manufacture it is better to use hand strokes for applying glue. Such equipment works at least twice as fast. However, the disadvantage of this mechanism is the inability to account for the exact consumption of glue.
In addition, such machines are divided into mixed application and continuous circulation devices. The main disadvantage of the second is the need for periodic washing.
Lamella splicing press
When choosing machines for the production of glued beams, which are used when splicing lamellas, the most important parameter is the length of the workpiece.When working on simple lines, the press is configured for a certain length of lamellas, and this is not very convenient when sorting, as boards of various lengths are obtained.
To optimize the process, continuous splicing lines are recommended. Such apparatuses press individual joints or segments. The best option would be to purchase an automatic line that performs several stages of the production of glued beams. Such equipment also takes on the functions of a tenoning machine. A similar line has a working capacity ten times higher than that of a semi-automatic press.
Gluing equipment
The most important equipment for the production of glued beams is vertical and horizontal presses. With the help of such machines, the lamellae are glued together along the face. When choosing equipment, one should take into account the parameters of the required finished product, as well as the availability of free space in the workshop.
The fact is that a horizontal press makes it possible to produce large-sized structures, as well as freely load and unload products. However, its disadvantage is that it takes up a lot of space. The vertical press works with a large number of hydraulic cylinders, which create uniform pressure over the entire area of the press.
The pressing process takes place using mechanical, pneumatic and hydraulic clamps. The latter type is considered the best option for the production of glued beams. Among its advantages, high power, uniform pressure distribution, the availability of service and the availability of spare parts should be highlighted.
Double side tenoning machine
To cut the mini-tires, which are then spliced on the press, a double-sided tenoning machine is used. Such equipment for the production of glued beams is purchased depending on the size of the production area, the required production volumes and, of course, financial capabilities.
When choosing, one should take into account the type of feed and bed, the width of the working table, as well as the types and number of cutters. Also, if necessary, you should choose a machine that will additionally have the function of applying glue to the miniship. This feature is optional, especially for small production.
Optional equipment
In addition to the above, additional equipment for the production of glued beams is also used. For example, these are shelves for finished products or glued lamellas, which are necessary for drying products and aging before machining. In small industries, certain machines can be used for several operations.
In order for the business to be successful, you must purchase high-quality technological equipment. In this case, you should evaluate parameters such as price, warranty and after-sales service, delivery and installation costs, ease of use and, of course, its brand and performance.
