Description

Technical Field

[0001] The present invention relates to the field of furniture production equipment, and particularly to an unmanned paint mist absorption integrated machine. Background Art

[0002] In furniture production, painting is one of the most important processes. In the current furniture production process, the cut plates are first manually transported to the painting room for fixation, and then the paint layer is sprayed on the to-be-painted surface of the plates through an automatic nozzle. After painting, the plates still need to be manually transferred to the paint drying room for drying.

[0003] However, since a large amount of paint mist particles are emitted during the painting process, the dispersion of the paint mist seriously harms the health of the operator. In the painting process, there is too much dependence on manual transportation and debugging. For example, for the loading process of each plate, multiple people are required to take turns to carry and adjust the installation position of the plate. After painting, manual transportation and installation position adjustment are still required to make the plate enter the painting room. This makes the overall efficiency depend on the efficiency of manpower, and full automation production cannot be achieved, resulting in low efficiency in the painting link. It also causes the operator to inhale a large amount of paint mist in the painting and paint drying environments. In addition, the dispersed paint mist will also affect the working environment in other areas of the workshop. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned existing technologies and provide an unmanned paint mist absorption integrated machine, which realizes high efficiency.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] The unmanned paint mist absorption integrated machine in the present invention includes a spray component, a liquid storage chamber, an absorption fan, a spray liquid recovery component, and a slag discharge component. Specifically:

[0007] The spray component is arranged on both sides of the painting component in the painting room and sprays downward the spray liquid with a paint mist coagulant, so that the paint mist coagulates and precipitates. The painting component includes a paint liquid distributor and a paint spray head arranged on the distributor. The plates are vertically placed and transported to the painting room through a conveying component and a conveying track, that is, the painting component is arranged on both sides of the conveying track, and the spray component in the present invention is arranged on both sides of the painting component.

[0008] The liquid storage chamber is arranged at the bottom of the painting room. A liquid leakage plate is arranged between the liquid storage chamber and the painting room. The spray liquid carrying paint slag passes through the liquid leakage plate and flows into the liquid storage chamber.

[0009] The absorption fan is arranged at one end of the painting room close to the paint drying room, and the absorption fan inhales the remaining paint mist.

[0010] The spray liquid recovery component is connected to the liquid storage cavity and the absorption fan. The spray liquid carrying paint residues converges with the paint mist inhaled by the absorption fan in the spray liquid recovery component, causing the paint mist to condense and precipitate for the second time.

[0011] The slag discharge component is connected to the spray liquid recovery component, filters the spray liquid carrying paint residues in the spray liquid recovery component step by step, discharges the paint residues, and returns the filtered spray liquid to the spray component to form a spray liquid circulation.

[0012] Further, the spray component is arranged at the top of the spray painting booth.

[0013] Further, the spray component includes a strip-shaped spray liquid distribution plate and spray liquid nozzles arranged on the spray liquid distribution plate.

[0014] Further, the spray liquid recovery component includes a recovery component housing and multiple filter layers. The spray liquid carrying paint residues is filtered layer by layer through the filter layers.

[0015] Further, a recovery component input port is provided at the top of the recovery component housing, and a recovery component output port is provided at the bottom of the top of the recovery component housing;

[0016] The recovery component output port is connected to the spray component;

[0017] The recovery component input port is connected to the spray component.

[0018] Further, a fan output pipe is provided at the output end of the absorption fan, and the fan output pipe is connected to the recovery component input port.

[0019] Further, a flow deflector is provided at the connection between the fan output pipe and the recovery component input port;

[0020] The flow deflector is an arc-shaped plate. One end of the flow deflector is connected to the fan output pipe, and the other end bends downward in an arc shape towards the recovery component input port. The setting of the flow deflector avoids the gas output from the fan output pipe directly flushing into the liquid storage cavity, avoiding the overflow of the liquid in the liquid storage cavity. Through the flow deflector, the air flow output from the fan output pipe and the liquid in the liquid storage cavity can be input into the spray liquid recovery component in parallel from the recovery component input port, enabling an absorption process between the gas and the liquid. The paint mist in the gas is absorbed by the paint mist coagulant in the liquid, generating paint residues for the second time, and each layer of the filter layer becomes a place to strengthen the absorption process.

[0021] Further, the filter hole diameters of the filter layers gradually decrease from top to bottom. This achieves a better filtering effect and avoids clogging of the filter holes.

[0022] Further, the slag discharge component is arranged on each layer of the filter layer;

[0023] On the side wall of the housing of the recovery component, slag discharge doors corresponding to each layer of filter layer are provided. The slag discharge doors are connected to the housing of the recovery component through torsion springs, and the slag discharge component discharges the paint slag through the slag discharge doors.

[0024] Further, the slag discharge component includes a cylinder, a piston rod disposed in the cylinder, and a shovel head connected to the end of the piston rod.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] 1) In the unmanned paint mist absorption integrated machine of the present invention, an automated paint mist absorption component is introduced. The paint mist coagulant is sprayed through the sprayer therein, so that the dispersed paint mist in the paint spraying chamber is absorbed. The spray liquid is recovered by the spray liquid recovery component, the paint slag therein is filtered out, and the filtered spray liquid is returned to the sprayer, completing the efficient absorption of the paint mist and avoiding the influence on the operator and the surrounding working environment.

[0027] 2) The unmanned paint mist absorption integrated machine of the present invention adopts a multi-stage filtration structure to achieve efficient separation of the spray liquid and the paint slag, avoiding blockage of the paint slag.

[0028] 3) The unmanned paint mist absorption integrated machine in the present invention is a combined form of liquid film absorption and fan absorption, and the paint mist absorbed by the fan is secondarily absorbed with the spray liquid, significantly improving the overall paint mist absorption rate and the utilization rate of the spray liquid.

[0029] 4) The setting of the guide plate in the present invention avoids the situation that the gas output from the fan output pipe directly rushes into the liquid storage cavity, causing the liquid in the liquid storage cavity to overflow. Through the guide plate, the air flow output from the fan output pipe and the liquid in the liquid storage cavity can be input into the spray liquid recovery component in parallel from the input port of the recovery component, enabling an absorption process between the gas and the liquid. The paint mist in the gas is absorbed by the paint mist coagulant in the liquid, generating paint slag again, and each layer of filter layer becomes a place to strengthen the absorption process.

[0036] The spraying component 3 is arranged on both sides of the paint spraying component 4 in the paint spraying chamber 1, and sprays downward the spraying liquid with paint mist coagulant, so that the paint mist coagulates and precipitates; wherein the paint spraying component 4 includes a paint liquid distributor and paint spraying heads arranged on the distributor. The plate 2 is vertically conveyed to the paint spraying chamber 1 through a conveying component and a conveying track 5, that is, the paint spraying component 4 is arranged on both sides of the conveying track 5, and the spraying component 3 in the present invention is arranged on both sides of the paint spraying component 4.

[0037] The liquid storage cavity 9 is arranged at the bottom of the paint spraying chamber 1. A liquid leakage plate 10 is arranged between the liquid storage cavity 9 and the paint spraying chamber 1. The spraying liquid carrying paint slag passes through the liquid leakage plate 10 and flows into the liquid storage cavity 9.

[0038] The spraying liquid recovery component 7 is communicated with the liquid storage cavity 9 and the absorption fan 8. The spraying liquid carrying paint slag and the paint mist inhaled by the absorption fan 8 converge in the spraying liquid recovery component, so that the paint mist coagulates and precipitates again.

[0039] The spraying component 3 is arranged at the top of the paint spraying chamber 1. The spraying component 3 includes a strip-shaped spraying liquid distribution plate and spraying liquid nozzles arranged on the spraying liquid distribution plate. The spraying liquid recovery component 7 of the recovery component includes a recovery component housing 71 and multiple filter layers 72. The spraying liquid carrying paint slag is filtered layer by layer through the filter layers 72.

[0040] A recovery component input port 73 is opened at the top of the recovery component housing 71, and a recovery component output port 74 is opened at the bottom of the top of the recovery component housing 71. The recovery component output port 74 is connected to the spraying component 3; the recovery component input port 73 is connected to the spraying component 3.

[0041] An absorption fan 8 is provided at one end of the spray booth 1 close to the baking booth 6, and the absorption fan 8 sucks in the residual paint mist.

The flow deflector 82 is an arc-shaped plate, with one end of the flow deflector 82 connected to the fan output pipe 81, and the other end facing the input port 73 of the recovery assembly in an arc-shaped downward bend. The setting of the flow deflector 82 prevents the gas output from the fan output pipe 81 from directly flushing into the liquid storage chamber 9, avoiding the situation of liquid overflow in the liquid storage chamber 9. Through the flow deflector 82, the air flow output from the fan output pipe 81 and the liquid in the liquid storage chamber 9 can be input into the spray liquid recovery assembly 7 in parallel through the input port 73 of the recovery assembly, enabling an absorption process between the gas and the liquid. The paint mist in the gas is absorbed by the paint mist coagulant in the liquid, generating paint sludge again, and the filter layer 72 in each layer becomes a place to strengthen the absorption process. The pore diameter of the filter layer 72 gradually decreases from top to bottom, thereby achieving a better filtering effect and avoiding clogging of the filter holes.

[0042] The slag discharge assembly is connected to the spray liquid recovery assembly 7, filters the spray liquid carrying paint sludge in the spray liquid recovery assembly 7 step by step, discharges the paint sludge, and returns the filtered spray liquid to the spray assembly 3 to form a spray liquid cycle. The slag discharge assembly is provided on each filter layer 72.
