Description

Pneumatic continuous production system and application of light matrix mesh bag container

technical field

The invention relates to a production equipment, in particular to a production system of light matrix net bag containers.

Background technique

Light substrate net bag container (Xu Chuansen (2001). Technology and equipment for full-light mist transplanting seedlings in lightweight net bag container. Forestry Science and Technology Communication. 2001 No.8 P.7-10) is an important technological innovation in recent years. A proper amount of soil, humus soil and mycorrhizal soil can be added to the matrix mesh bag container. The fibrous net bag material can be non-woven cloth, i.e. non-woven fabric material, and can also be woven cloth, paper or other materials with mesh shape (the present invention collectively refers to it as mesh cloth). This container is mainly suitable for the cultivation of container seedlings of main afforestation tree species throughout the country at present, and can basically meet the needs of container seedling cultivation of some main coniferous trees and broad-leaved afforestation tree species nationwide. It can also be used for the cultivation of container seedlings such as most gardens, greening, flowers, vegetables, economic crops, and crop seedlings in current production.

The existing light matrix mesh bag container production machine adopts the feeding method of the screw. The disadvantage is that the light matrix is worn, the fiber is damaged, and the particle size becomes thinner, resulting in poor air permeability of the matrix, uneven structure, and easy water accumulation. At the same time, the screw is severely worn and the cost High, the screw feeding speed is slow.

There is a container machine produced by Danish Ariad Company. It uses vacuum and negative pressure to absorb the light matrix of high-level peat containing a large amount of fibers and fill it in a non-woven container. The working process is intermittent. of. That is, before the non-woven fabric container stops, the upper and lower boxes of the sealed box are closed and closed to ensure airtightness. At this time, the equipment that can generate vacuum and negative pressure is started, and the matrix is sucked into the air through vacuum and negative pressure. In a non-woven container. When the container is full, the airtight box is opened, and the container is pulled out and moved forward for a certain distance, and so on. When the container is intermittently stationary, the machine performs fast dry cutting on the container at the same time. Since the matrix contains a large amount of fibrous high-level peat, the dry cutting will not disperse.

The main problem is: the vacuum and negative pressure suction are limited, and the suction is small. Since only negative pressure air suction is used, the maximum negative pressure does not exceed a negative standard atmospheric pressure value, and the general working vacuum is less than 0.05MPa; The particle size is uneven, the friction is high, and the material often appears in the process of building a shed and blocking; the matrix particle size, humidity, and specific gravity are strictly required; The container stops moving forward in the static stage, and the substrate is fully absorbed, and the container cannot be continuously produced; the fiber content of the substrate is required to be high, and it is designed with high-level peat as the main raw material of the substrate, otherwise, the container is easy to disperse during dry cutting; strict requirements on equipment sealing ,complex structure. Therefore, there is an urgent need for a container with high wind pressure, large air volume, less strict requirements on sealing, continuous and rapid continuous production, and no mandatory requirements for light-based particle size and specific gravity, simple structure, low cost, and can carry out multiple containers at the same time. Production, production equipment with excellent performance.

Filling and dust removal system, including a three-way box, the three-way box has a front inlet, a rear outlet and a middle outlet, and a cylindrical grid is arranged inside, and the feeding pipe extends from the front inlet of the three-way box. Into the cylindrical grid net, the light matrix is filled into the mesh bag container in the grid net, and sent out from the rear outlet. There is a pressure sensor at both ends of the filling place, and the three-way box body The middle outlet is connected with a vacuum cleaner;

The traction system includes a speed-regulating motor and a traction conveyor belt driven by it, which provides driving power for the net bag container; the speed-regulating motor is equipped with a manual speed-regulating button.

The control system controls the air intake volume of the air volume regulating valve on the main pipe and the running speed of the traction motor through the signal sent by the pressure sensor installed at the filling place.

The production system of the present invention also includes a container rewinding system or a fast sectioning system located behind the traction system, the rewinding system includes a motor and a reel, the reel is provided with a tensioning wheel, and the motor drives the tension through a belt wheel turns;

The section cutting system includes a sensor for measuring the running length of the light matrix mesh bag container, a motor and a rotating blade driven by the motor, and the sensor for measuring the walking length of the light matrix mesh bag container controls the rotating blade to cut the light matrix mesh bag container into a certain A segment of the length, the sensor here can be a sensor wheel that rotates as the mesh container travels, thereby measuring the travel length of the container.

The air volume regulating valve on the air intake pipe and the air intake branch pipe is a manual valve. The pressure air source connected to the air intake pipe and the pressure air source connected to the air intake branch pipe can be the same air source, and the air intake pipe and the air intake branch pipe pass through a The air intake main pipe is connected with the pressure air source, and the air intake main pipe is provided with a parallel air volume regulating valve and a manual valve, and the air volume regulating valve is controlled by the control system.

Before the system is cut off, the present invention also has a container wetting device for soaking the canned light matrix mesh bag container. Before cutting, whether to wet the container depends on the fiber content in the light matrix. If there is more fiber content in the matrix, the matrix will not disperse after cutting, so it does not need to be soaked; if the fiber content in the matrix is less, the matrix after cutting If it is easy to scatter, it can be soaked before cutting into sections. The wet cutting method is: before the cutting system, that is, during the process of being drawn after canning, a water pipe is installed above the container, and a row of nozzles is installed on the water pipe to spray water on the container. A water tank and a filter screen can also be arranged under the conveyer belt, and the water is connected with a water spray pipe through a water pump after being filtered, thereby realizing water recycling.

Moreover, there is a buffering distance between the winding system and the traction system.

work process

Before starting the machine, the container mesh bag material is manually pulled out from the three-way box. During the pulling process, only the power supply of the electric heat sealer is turned on. The electric heat sealer will automatically roll into a cylindrical shape through the forming machine and walk. Net bag material, heat-sealed into an empty net container. Tie up the net bag opening outside the three-way box, and then turn on the whole machine. Adjust the pneumatic light matrix conveying system, adjust the rotary feeder and the speed regulating motor on the rotary feeder and the air volume control valve in the main air intake pipe. When only the manual valve located on the upper air intake pipe is opened, (close The light substrate in the air material mixing chamber will be forced to blow into the discharge pipe and enter the mesh bag container forming and heat sealing system. When only the manual valve located on the lower inlet branch pipe is opened (while the valve on the upper branch pipe is closed), when a gas with positive pressure is ejected from a nozzle with a suddenly narrowing diameter into the discharge pipe at high speed, the gas around the nozzle A certain vacuum and negative pressure suction is generated in the chamber, and the light matrix is sucked into the discharge pipe. When the material enters the discharge pipe, it is forced to be blown and pressed from the discharge pipe to the mesh bag container by positive pressure. Heat sealing system. When the valves on the two inlet pipes are properly opened, the light matrix is still conveyed in a fluidized state without clogging, and is conveyed to the mesh bag container forming and heat sealing system.

The above three pneumatic feeding methods can completely solve the production problems that often cause material clogging due to the small bulk density of the light matrix, uneven particle size, unsmooth blanking, and easy tower shed. Any one of the above three methods can be adopted in the production process. When only the lower inlet branch pipe is opened, if the light substrate is blocked, the valve on the upper branch pipe can be opened immediately, and the blocked material can be forced into the discharge pipe, and then the upper branch valve can be closed after the blockage is removed. The advantage of negative air suction is that there will be no dust pollution in the hopper of the rotary feeder. The disadvantage is that the light matrix is very easy to block. Pressure feeding pneumatic conveying is not easy to block due to high gas pressure, but it is easy to generate dust in the feed box of the rotary feeder. The combination of the three pneumatic feeding methods, that is, when the upper and lower inlet pipe valves are properly fully opened, the problem of blockage in production is solved, and the problem of dust is also eliminated.

The present invention adopts pressure-feeding type pneumatic force; suction and pressure-feeding mixed type pneumatic force; and a light matrix pneumatic conveying system that can also be fluidized, has large wind pressure, large air volume, less strict requirements on sealing, and strict requirements on the particle size of light base, There is no mandatory requirement for specific gravity, which can reduce clogging, or non-clogging, continuous and rapid production of light matrix mesh bag containers.

When the light substrate is blown into the mesh bag by the wind, because the mesh diameter of the mesh material is smaller than the diameter of the substrate particle size, the result is: the wind will send the light substrate into the mesh bag, and the wind and dust will pass through the mesh. sprayed out and sucked up by a vacuum cleaner connected to the three-way box. Adjust the indexing speed of the container that has been filled with light matrix mesh bags, so that the container loading position is located in the middle of the tee box. The air suction volume of the vacuum cleaner should be greater than the air intake volume. Adjust the air intake volume and the index walking speed of the light matrix mesh bag container to match each other to ensure the system works normally. For avoiding to produce following two kinds of situations: 1 light substrate mesh bag container traction speed is too fast, and the result is: the inside substrate of net packing is not filled yet, and container just is pulled out from the three-way casing the inside. II The wind force of suction and feeding is too large or the traction speed of the light matrix mesh bag container is too slow. The incoming generation has a certain pressure wind, which is blocked by the matrix in the pipe, and then the wind direction is forced to turn around and blow out from the mouth of the air inlet pipe. In order to avoid the above two situations, a sensor is installed at the front and rear of the net bag container loading position in the tee box to detect the net bag container filling state. When the matrix at the outlet of the mesh bag container is not full, the sensor sends out a signal to reduce the traction speed; a sensor is installed in the matrix filling direction, that is, the direction of blowing material, and when the matrix inside the mesh bag is full, a signal is sent out. Reduce air intake. In this way, continuous production is realized. Filled light matrix mesh bag containers are either pulled into a container rewind system or into a container cut-to-section system.

Sometimes when the container is produced, it is not necessary to cut into sections immediately, but the produced light matrix mesh bag container is rolled into rolls and stored until the seedling season and then cut into sections. And there are many cases like this, in which case a container rolling bag system can be installed.

Rewinding roll bag system, when the container is pulled into the buffer zone by the front end, the light matrix mesh bag container has a hanging curvature, and the back is the winding roll rack. Adjust the tension of the belt friction wheel of the winding frame so that the produced light matrix mesh bag container can be rolled into rolls in time.

Rapid cutting system, if the fiber content in the matrix is more, the matrix will not disperse after cutting, then it can be cut into sections dry; When the dry or wet container is pulled by the speed-regulating conveyor belt at the front end of the system, it is pulled into the sensor wheel, and the sensor wheel rotates passively and synchronously. When the wheel rotates to a certain angle, the signal sent by the sensor, the high-speed rotating motor, and the moving blade Rotate once, so the container is cut off. Of course, the sensors here may also be other types of sensors. The cut container is conveyed to the back by the conveyor belt, or manually moved to the seedling tray, or automatically placed into the seedling tray.

The three-way box body can also be made of transparent material to facilitate observation and understanding of the filling situation of the container. When it is necessary to produce mesh bag containers of different diameters, the Venturi tubes of different specifications, soft sealing sleeves of different specifications, and other accessories can be replaced at the same time to ensure the consistency of the system.

The light matrix net bag container production system of the present invention adopts pneumatic continuous production, has high production speed, high efficiency, low cost and saves manpower. Moreover, the light matrix net bag container produced by the production system of the present invention is filled with positive and negative pressure gas to drive the light matrix, the particles and fibers of the matrix are not forced to be squeezed or broken, and the matrix is sucked and dust-removed. Therefore, the tightness between the substrates is suitable, the structure is uniform, the air permeability is good, and it is not easy to accumulate water.
