Description

Technical Field

[0001] The invention relates to the technical field of dust-proof net production, in particular to soil covering dust-proof net processing and leveling equipment. Background Art

[0002] The soil covering dust prevention net is a covering material used to control dust pollution and improve environmental quality. It is widely used in construction sites, road projects, mining and other places. It usually adopts a mesh structure supported by materials such as polyethylene to prevent dust from flying.

[0003] During the processing of the covering dust-proof net, it is necessary to control the mesh size of the covering dust-proof net to reduce the amount of flying dust. Moreover, since the covering dust-proof net is basically made of polyethylene, it is very easy to soften under the exposure to the sun, causing the covering dust-proof net to deform, thereby affecting the mesh size of the covering dust-proof net. When the mesh size becomes larger, the dust-proof effect of the dust-proof net will become worse. Summary of the invention

[0004] The purpose of the present invention is to provide equipment for processing and leveling a soil covering and dustproof net.

[0005] The technical problem solved by the present invention is to solve the problem in the prior art that it is difficult to judge whether the mesh of the dustproof net is easily deformed under the sun, resulting in poor dustproof effect.

[0006] The present invention can be implemented through the following technical scheme: soil covering dustproof net processing and leveling equipment, including an upper support mechanism and a lower support mechanism for leveling the test dustproof net, and a second heating roller, an air permeability detection mechanism and a first cooling roller are sequentially arranged on the upper support mechanism and the lower support mechanism.

[0007] A further technical improvement of the present invention is that side guide bases for guiding and limiting the test dustproof net are symmetrically arranged on both sides of the lower bracket mechanism.

[0008] A further technical improvement of the present invention is that: a first guide groove for rotatably mounting the first temperature-lowering roller and a second guide groove for rotatably mounting the second temperature-raising roller are cooperatively provided on the lower bracket mechanism and the upper bracket mechanism.

[0009] A further technical improvement of the present invention is that the air permeability detection mechanism comprises a spraying slot provided on the lower support mechanism and a detection cavity provided on the upper support mechanism, and the spraying slot is connected to an output pipe for realizing the spraying of simulated dust gas.

[0010] A further technical improvement of the present invention is that the output pipe is installed at the output end of the mixing box through an air pump, the top of the mixing box is connected to a dust inlet for dust entry, and the top of the mixing box is provided with an air blast pipe for gas replenishment.

[0011] A further technical improvement of the present invention is that a retractable air bag in a retractable state is provided at the bottom of the mixing box, and the retractable air bag cooperates with the gas entering from the blast duct.

[0012] A further technical improvement of the present invention is that a detection sensor for detecting dust content is arranged inside the detection cavity, and an exhaust pipe for exhausting gas is also connected to the detection cavity.

[0013] A further technical improvement of the present invention is that the interior of the detection cavity is also connected to a self-cleaning air pipe for allowing clean gas to enter, and the detection cavity and the ejection groove are respectively provided with ejection grooves for filtering large particle impurities.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application processes the test dustproof net by first passing it through a second heating roller, then testing it using an air permeability testing mechanism, and finally continuing to cool and smooth it using a first cooling roller. That is, during this process, the second heating roller is used to simulate exposure to the sun to soften the test dustproof net, and then it is transported to the air permeability testing mechanism for testing to determine whether the mesh of the test dustproof net has changed, thereby continuing to determine the quality of the test dustproof net. After obtaining the result, the test dustproof net is cooled by the first cooling roller, and the test dustproof net can be smoothed during this process. The test dustproof net after heating is in a relatively soft state, and is easy to smooth after contact with the first cooling roller.

[0016] 2. The present application realizes the entry of dust by utilizing the dust inlet port. The dust enters into the interior of the mixing box, which increases the pressure inside the mixing box. At this time, the retractable airbag is inflated. At this time, the action of the blower will further inflate the retractable airbag. At this time, the dust can be evenly dispersed in the air. When in use, the gas can be directly output from the output pipe to simulate the dust being lifted up at a certain pressure, so as to judge the dust-proof effect of the dust-proof net and obtain a more accurate result.

DETAILED DESCRIPTION

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] See also Figure 1-4 As shown, the soil covering dustproof net processing and leveling equipment includes a lower bracket mechanism 3 and an upper bracket mechanism 1 for supporting and limiting the soil covering dustproof net, and side guide bases 25 for limiting the test dustproof net 2 are symmetrically arranged on both sides of the lower bracket mechanism 3, that is, when in use, the test dustproof net 2 is passed through the side guide bases 25 in sequence, and the test dustproof net 2 can pass through the upper bracket mechanism 1 and the lower bracket mechanism 3. At this time, the air permeability detection mechanism 4 arranged on the upper bracket mechanism 1 and the lower bracket mechanism 3 is used to perform air permeability detection to ensure that the heat resistance of the test dustproof net 2 is tested, and at the same time, the upper bracket mechanism 1 and the lower bracket mechanism 3 can realize the leveling function of the test dustproof net 2 to ensure the leveling state of the test dustproof net 2.

[0025] As a further embodiment of the present application, in the present application, the upper support mechanism 1 and the lower support mechanism 3 are slidably connected via a sliding limit column 5, wherein the upper support mechanism 1 and the sliding limit column 5 are slidably connected, and the sliding limit column 5 is fixedly mounted on the lower support mechanism 3. In the present application, the upper support mechanism 1 is fixedly mounted on the output end of the longitudinal cylinder, and the longitudinal cylinder is used to control the longitudinal movement of the upper support mechanism 1 to control the distance between the upper support mechanism 1 and the lower support mechanism 3.

[0026] In the present application, a processing mechanism for the test dustproof net 2 is respectively arranged on both sides of the air permeability detection mechanism 4. Specifically, the processing mechanisms of the upper support mechanism 1 and the lower support mechanism 3 are symmetrically arranged, and the processing mechanism structures of the upper support mechanism 1 and the lower support mechanism 3 are the same, so the lower support mechanism 3 is taken as an example, that is, the lower support mechanism 3 includes a first base 7, and a first guide groove 8 and a second guide groove 9 are opened on the first base 7, wherein the first guide groove 8 and the second guide groove 9 are respectively arranged at both ends of the air permeability detection mechanism 4, wherein a first cooling roller 6 is rotatably arranged inside the first guide groove 8, and a second heating roller 10 is rotatably arranged inside the second guide groove 9. When in use, the test dustproof net is first heated by the second heating roller 10, at this time simulating the temperature obtained by sunlight, and then the heated test dustproof net 2 is transferred to the inside of the air permeability detection mechanism 4 for testing and processing, and after the testing and processing, in order to ensure the transfer stability of the test dustproof net 2 and facilitate storage, the test dustproof net 2 is cooled by the first cooling roller 6.

[0027] The upper bracket mechanism 1 includes a second base 24, wherein the first base 7 and the second base 24 are arranged opposite to each other, and a limiting groove for realizing the movement and limiting of the test dustproof net 2 is also arranged inside the first base 7 and the second base 24. When in use, the test dustproof net 2 passes through the limiting groove and enters the interior of the first cooling roller 6. At the same time, due to the contact and adhesion connection between the bonding surfaces of the second base 24 and the first base 7, the influence of the permeability detection mechanism 4 on the first cooling roller 6 and the second heating roller 10 can be reduced. At this time, the detection space of the permeability detection mechanism 4 is relatively independent.

[0028] The air permeability detection mechanism 4 includes a detection cavity 12 and an ejection groove 19, wherein the ejection groove 19 is opened in the middle position of the first base 7 for realizing the ejection of dust-carrying gas, and at the same time, a detection cavity 12 is opened on the second base 24, and the detection cavity 12 is used to detect the dust content, so as to judge the amount of dust passing through the dustproof net, so that the quality of the test dustproof net 2 can be accurately detected to realize the stable production of the test dustproof net 2.

[0029] A removable filter plate 20 is installed inside the ejection slot 19, which is used to control the dust particle size acting on the test dustproof net 2 to ensure that the particle size reaching the test dustproof net 2 remains basically consistent. At the same time, a detection sensor 11 is arranged inside the detection cavity 12. The detection sensor 11 is used to test the amount of dust received by the test dustproof net 2, so as to judge the dustproof effect of the test dustproof net.

[0030] In order to allow the gas mixed with dust to enter, a spray port 13 is fixedly installed inside the spray groove 19, and the spray port 13 is connected to the output pipe 14, wherein the output pipe 14 is installed at the output end of the air pump 15, and the output end of the air pump 15 is connected to the inside of the mixing box 17 through the mixing outlet 16, that is, the air pump 15 is used to extract the mixed gas in the mixing box 17 to the output pipe 14, so that the spray port 13 is used to realize the spraying, and the mixed gas is preliminarily filtered by the detachable mesh plate 20 and directly passes through the test dustproof net 2, and the gas is detected by the detection sensor 11 to determine the amount of dust in the gas, thereby determining the dustproof effect of the test dustproof net 2, which is convenient for determining the quality of the test dustproof net 2, so that the heating function of the test dustproof net 2 by the second heating roller 10 on the test dustproof net 2 can be simulated to determine the dustproof effect of the test dustproof net 2 in a relatively hot state.

[0031] In order to achieve sufficient mixing of dust and gas, a dust inlet 18 and a blast duct 22 are also provided on the mixing box 17. The blast duct 22 is connected to the output end of the blower 21. The blower 21 is used to blow air to the mixing box 17, so that the dust added through the dust inlet door 18 can be fully mixed with the air, so that after mixing, it can evenly enter the interior of the ejection slot 19 through the air pump 15, thereby realizing the simulation of dust.

[0032] In order to fully mix the gas and dust and make the dust evenly dispersed in the gas, a retractable airbag 23 is installed at the bottom of the mixing box 17. When in use, the air pump 15 does not work first, and the blower 21 and the air pipe 22 are used to gradually make the retractable airbag 23 open under the action of the blower 21 to achieve uniform mixing of the gas and dust. Subsequently, when the air pump 15 is working, the blower 21 does not work, and the dust no longer enters the interior of the mixing box 17. At this time, the air pump 15 can simulate the action of the evenly mixed gas on the interior of the ejection slot 19 to achieve the simulation function.

[0033] As a further embodiment of the present application, when dust is inside the detection chamber 12, since the size of the test dustproof net 2 located on the detection chamber 12 is certain at this time, the test dustproof net 2 is in a stationary state at this time. At this time, the dust inside the detection chamber 12 and the ejection slot 19 will continue to spread, and if the gas is not discharged in time, there will be a high pressure. Therefore, an exhaust pipe 27 is provided on the second base 24, wherein the exhaust pipe 27 is used to realize the immediate discharge of gas. At the same time, a self-cleaning air pipe 26 is also provided on the second base 24, and the self-cleaning air pipe 26 is used to realize the discharge of clean gas. At this time, the gas containing dust will be squeezed out from the inside of the exhaust pipe 27, thereby realizing the guarantee of the cleanliness of the ejection slot 19 and the detection chamber 12, thereby facilitating the precise processing of the test dustproof net 2.

[0034] When the present invention is used, the test dustproof net 2 is first guided to pass through the base 25 from the side to achieve a preliminary definition of the position of the test dustproof net 2, and then the distance between the first base 7 and the second base 24 is controlled by an external power device until the first base 7 and the second base 24 are closely attached to each other, so as to separate the second heating roller 10, the first cooling roller 6 and the air permeability detection mechanism 4 from each other, thereby avoiding the influence of the air permeability detection mechanism 4 on the first cooling roller 6 and the second heating roller 10;

[0035] Specifically, the test dust-proof net is first heated by the second heating roller 10 to simulate the temperature change under the sun, so as to heat the test dust-proof net 2 made of polyethylene material, and determine whether the temperature has an effect on the mesh of the test dust-proof net 2. Then, after the air permeability detection mechanism 4 detects the above requirements, the test dust-proof net is cooled by the first cooling roller 6, and the rotation of the adjacent first cooling rollers 6 can squeeze and flatten the test dust-proof net 2, so that the test dust-proof net 2 after the simulated training is quickly cooled and flattened, thereby ensuring the quality of the generated test dust-proof net 2;

[0036] When the air permeability detection mechanism 4 is used to detect the test dustproof net 2, the air pump 15 does not work first, and the blower 21 and the air blowing pipe 22 are used to work, so that the retractable air bag 23 is gradually expanded under the action of the blower 21, so that the gas and dust are evenly mixed. Then, when the air pump 15 is working, the blower 21 does not work, and the dust no longer enters the interior of the mixing box 17. At this time, the air pump 15 can simulate the uniformly mixed gas to act on the interior of the ejection slot 19, so as to realize the simulation function;

[0037] When dust is inside the detection chamber 12, since the size of the test dustproof net 2 located on the detection chamber 12 is fixed at this time, the test dustproof net 2 is in a stationary state. At this time, the dust inside the detection chamber 12 and the ejection slot 19 will continue to spread, and if the gas is not discharged in time, it is easy to have a large pressure. Therefore, an exhaust pipe 27 is provided on the second base 24, wherein the exhaust pipe 27 is used to realize the immediate discharge of gas. At the same time, a self-cleaning air pipe 26 is also provided on the second base 24, and the self-cleaning air pipe 26 is used to realize the discharge of clean gas. At this time, the gas containing dust will be squeezed out from the inside of the exhaust pipe 27, thereby ensuring the cleanliness of the ejection slot 19 and the detection chamber 12, thereby facilitating the precise processing of the test dustproof net 2.
