Description

A horizontal drum straw glue mixing device

1. Technical field

The utility model belongs to the design of a straw glue mixing device, in particular to the design of a laboratory-used horizontal drum straw glue mixing device. the

2. Background technology

my country's forest resources are scarce. As a huge renewable resource, crop straw is mainly composed of lignin, cellulose, hemicellulose and some ash impurities. It is very similar to the components of broad-leaved wood and is a good substitute for wood. raw materials. Crop straw particleboard is a multi-layer structure board made of straw as raw material, green and environmentally friendly isocyanate resin as adhesive, and hot-pressed after directional paving, without formaldehyde pollution. It has the characteristics of light weight, excellent physical and mechanical properties and environmental protection. It is an ideal new material for environmental protection and energy saving. It can be used in construction industry, furniture manufacturing, flooring, packaging and interior decoration. It can not only alleviate the contradiction between timber supply and demand, but also meet market demand. But its production technology is not very mature now, and the performance and production process of straw board need to be studied through a large number of experiments in the laboratory. At present, in modern industrial production, single-shaft ring-type glue mixing devices, double-shaft ring-type glue-mixing devices and drum-type glue-mixing devices are mainly used. These three glue-mixing devices are all suitable for the production of wood shavings and crop straw particleboards with medium output. Laboratory pressing of straw particleboard usually uses manual glue mixing, which is uneven and wastes glue. The uncured isocyanate adhesive has certain toxicity. Manual glue mixing is harmful to human health and low work efficiency. Therefore, in order to better study the production process and various performances of oriented straw boards, it is necessary to design a laboratory-use roller-type straw-glue mixing device that can complete a certain amount of tasks and is compact and coordinated. the

3. Contents of the invention

In order to improve the efficiency of pressing straw particleboard in the laboratory, overcome the lack of uneven manual glue mixing, and better study the performance of straw particleboard, the utility model designs a horizontal drum straw glue mixing device for experiments. The glue mixing device Not only can the straws used in experiments to press the straw particleboard be evenly mixed with glue, but also the efficiency is improved. the

The technical scheme that the utility model solves its technical problem adopts is:

A laboratory-used horizontal roller straw glue mixing device is composed of a roller, a feeding device, a glue spraying device, a transmission device and a discharging device. The above-mentioned drum is a cylinder with a lifting board inside, and the opening at one end is designed to have a certain taper to prevent the straw from being thrown out when the drum rotates. The bottom of the cylinder is a circular plate for connection with the flange. the

The above-mentioned feeding device mainly includes a feeding port, and manual feeding is adopted. the

The above-mentioned glue spraying device is composed of a glue pump and four nozzles, and the two nozzles form a pair, forming an angle of 120 degrees, and spray glue in the drum. the

The transmission device includes a main shaft, a speed-regulating motor, a belt, and a pulley. The main shaft is fixed on the base bracket through two outer spherical bearings with seats, the motor is below the base bracket, and the main shaft is driven to rotate through the pulley, and the installation position of the pulley can also be selected to be installed in the middle of the two outer spherical bearings with seats, so that The overall size of the machine can be reduced. the

The above-mentioned discharge device mainly includes a discharge port, which adopts manual discharge. the

The beneficial effect of the utility model is that the work efficiency can be improved while the straw shavings with uniform sizing can be obtained, and the direct harm of the glue to the human body can be reduced. Moreover, the equipment has a small and harmonious appearance and is suitable for laboratory research. the

5. Specific implementation

Referring to Fig. 1 and Fig. 2, a laboratory horizontal roller straw glue mixing device is composed of a roller, a feeding device, a glue spraying device, a transmission device and a discharging device. The straw shavings are put into the drum 1 from the feed port 2 according to the required amount, and the glue spraying device 3 is ready to be placed at the nozzle 6 . After the preparatory work is completed, start the power switch, observe the rotating speed of the drum, adjust the speed-regulating motor 5 to make its speed compatible with the amount of shavings, and the motor drives the drum to rotate through the belt pulley. Due to the rotation of the drum, the shavings are lifted to a certain height by the partition 4 and fall down to form a continuous shaving curtain; the adhesive is atomized and sprayed directly on the shaving curtain, and the glued shavings are turned up and down in the drum with the rotation of the drum , There is a certain friction between each other, so that the glue sprayed on the shavings is transferred, so as to obtain evenly sized shavings. Turn off the power switch, and after the drum is still, unload the drum, and pour the material out from the discharge port 7. the
