Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spray room, in particular to a rhombic spray room. BACKGROUND

[0002] The spray room is used to provide a closed space for painting or powder spraying on the formed workpiece, which can prevent the leakage of paint from causing environmental pollution and improve the work efficiency of spraying. After the shell of the automobile or the aluminum material is formed, it is subjected to surface treatment and then enters the spray room for painting or powder spraying, realizing the flow line operation and greatly improving the production efficiency.

[0003] The traditional spray room body has a U-shaped cross section along the horizontal direction. For example, the Chinese patent application with the publication number CN103657940A and the title of "a new type of high efficiency U-shaped vertical line spray powder room" discloses that the opening of the U-shaped spray room is the feeding port, the nozzle of the spray gun faces the rear side of the spray room, the workpiece to be sprayed enters the spray room body from one side of the feeding port, and then passes around the spray gun and goes out from the other side of the feeding port. The technical solution adopts the opening of the U-shaped spray room as the feeding port, and the width of the feeding port is consistent with the width of the U-shaped spray room. When the spray gun sprays the workpiece to be sprayed, the powder sprayed by the spray gun is easy to overflow to the feeding port due to the large size of the feeding port, which affects the powder adhesion effect. The two air extraction ports of the technical solution are arranged on the two sides of the rear end of the spray room, and have a large air extraction speed. The air flow rate on the two sides of the spray room is high, which affects the stability of the air flow in the spray room, causes a part of the paint sprayed by the spray gun to be directly extracted by the air extraction port, and makes it difficult for the paint to be adsorbed on the surface of the workpiece. In addition, the air flow also causes the paint to be unevenly adsorbed on the surface of the workpiece, which affects the adhesion effect of the powder paint on the surface of the workpiece.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0034] The embodiment of the present application is described below Figures 1 to 7 , a rhombic spray room.

[0035] A rhombic spray room, comprising a spray room body 1 and a powder blocking body 2, the cross section of the spray room body 1 and the powder blocking body 2 along the horizontal direction is rhombic, the powder blocking body 2 is installed inside the spray room body 1; two side acute angles in the spray room body 1 are respectively provided with auxiliary exhaust buckets 3, the front obtuse angle in the spray room body 1 is provided with a main exhaust bucket 4, and the rear obtuse angles in the spray room body 1 and the powder blocking body 2 are respectively provided with feeding ports 6; the two side acute angles and the front obtuse angle of the powder blocking body 2 are respectively provided with air inlets 10, the main exhaust bucket 4 and the auxiliary exhaust bucket 3 are respectively provided with air inlets 10; the spray gun 9 is arranged inside the powder blocking body 2, and the main exhaust bucket 4 corresponds to the spraying direction of the spray gun 9.

[0036] The rhombic spray room of the embodiment is used for powder spraying of a shaped workpiece. Specifically, the two side acute angles in the spray room body 1 are provided with auxiliary exhaust buckets 3, the auxiliary exhaust buckets 3 can suck away part of the airflow inside the powder blocking body 2, avoid the airflow inside the powder blocking body 2 flowing to the main exhaust bucket 4, prevent the airflow rate inside the powder blocking body 2 from rising, so that the air flow speed from the feeding port 6 to the main exhaust bucket 4 is low, effectively reducing the wind speed, which is beneficial to the adhesion of the powder on the surface of the workpiece, and improves the powder application rate. Since the air flow speed inside the powder blocking body 2 is low, it can effectively prevent the powder inside from overflowing.

[0037] On the one hand, a large number of suction buckets can meet the suction demand in the spraying room at a small suction rate, and on the other hand, the three suction buckets are arranged in a triangular manner, and the spray gun 9 is rapidly released as power by compressed air, so that the spray gun 9 sprays powder and gas at the same time in the process of spraying powder, the gas sprayed by the spray gun 9 enters the suction bucket along the powder blocking body 2, which greatly reduces the influence on the movement track of the powder coating and is beneficial to the adhesion of the powder coating to the workpiece, thereby improving the powder adhesion rate. Moreover, since the main suction bucket 4 is shielded by the workpiece between the spray gun, the airflow sprayed by the spray gun 9 is dispersed to both sides of the workpiece, which is called lateral airflow, and the lateral airflow enters the main suction bucket 4 and the side suction bucket 3 after being blocked by the powder blocking body 2. Therefore, based on the blocking and dispersion of the lateral airflow, the airflow speed in the powder blocking body 2 can be reduced, and the powder coating sprayed by the spray gun 9 can be more fully adhered to the surface of the workpiece.

[0038] The cross section of the spraying room body 1 and the powder blocking body 2 along the horizontal direction is in the shape of a rhombus, the cross section of the rear side in the powder blocking body 2 along the horizontal direction is in the shape of a V, which can block the coating in the powder blocking body 2, the width of the inlet 6 at the obtuse angle of the rear side in the spraying room body 1 and the powder blocking body 2 is only large enough to install the spray gun and the inlet, which avoids the width of the inlet 6 being too large to prevent the coating from overflowing from the inlet 6, and the three suction buckets are arranged in a triangular manner, which only needs a small suction rate to reduce the airflow speed in the powder blocking body 2 and prevent the coating from floating out of the inlet 6.

[0039] The acute angle of the two sides inside the spraying room body 1 is 65° to 89°, and the obtuse angle of the front side and the rear side inside the spraying room body 1 is 95° to 125°. Preferably, the acute angle is 80°, and the obtuse angle is 110°. It should be noted that in the rhombic spraying room of the present application, the cross section of the spraying room body 1 and the powder blocking body 2 along the horizontal direction is in the shape of a rhombus, which refers to the general shape of the spraying room body 1 and the powder blocking body 2, rather than a strict rhombus. In actual application, the acute angles of the cross section shape of the two sides of the spraying room body 1 and the powder blocking body 2 along the horizontal direction can have different angles, and the lengths of the two adjacent sides of the cross section shape can be different.

[0040] The height of the air inlet 10 is consistent with the height of the powder blocking body 2, and the width of the air inlet 10 is consistent with the width of the suction hole of the auxiliary suction bucket 3 and the main suction bucket 4, so that the size of the air inlet 10 is consistent with the size of the suction hole of the auxiliary suction bucket 3 and the main suction bucket 4, which is convenient for the auxiliary suction bucket 3 and the main suction bucket 4 to suck away the airflow in the powder blocking body 2.

[0041] The spray head of the spray gun 9 is provided with a plurality of spray heads arranged along the horizontal direction, and the width of the plurality of spray heads arranged along the horizontal direction is greater than the width of the workpiece, so that the workpiece facing the spray gun 9 can be uniformly adhered to the surface of the workpiece when spraying powder, thereby saving the left and right sliding steps.

[0042] The spray gun 9 is a mute spray gun. The electrostatic spray gun uses electrostatic force, which is invisible to the eyes and is called third-party force, to make the paint particles close to the coated object adhere. Since the electrostatic paint particles almost all adhere to the coated object, the coating efficiency can be greatly improved.

[0043] Further, the powder blocking body 2 comprises a roller blind cylinder 13 and a roller blind belt 14, one end of the roller blind belt 14 is connected to the peripheral surface of the roller blind cylinder 13, and the roller blind belt 14 can be wound on the roller blind cylinder 13. The side surface of the spray house body 2 is provided with a support block for mounting the roller blind cylinder 13.

[0044] In operation, the roller blind belt 14 wound on the peripheral surface of the roller blind cylinder 13 can be rolled down by rotating the roller blind cylinder 13, forming a relatively closed space, preventing the powder sprayed by the spray gun 9 from splashing out of the powder blocking body 2. When the work is completed, the roller blind belt 14 can be wound up by rotating the roller blind cylinder 13, facilitating the cleaning of stains inside the spray house.

[0045] Further, the powder blocking body 2 comprises a roller blind cylinder 13 and a roller blind belt 14, one end of the roller blind belt 14 is connected to the peripheral surface of the roller blind cylinder 13, and the roller blind belt 14 can be wound on the roller blind cylinder 13. The side surface of the spray house body 2 is provided with a support block for mounting the roller blind cylinder 13.

[0046] The powder blocking plate 8 is installed on the top of the powder blocking body 2, which can prevent the powder sprayed by the spray gun 9 from splashing upwards. The air pipe 221 can blow a slight breeze into the upper part of the powder blocking body 2 through the air outlets 222, effectively preventing the powder sprayed by the spray gun 9 from splashing upwards. The number of air outlets 222 is 35-70. The air pipe 221 blows a slight breeze into the upper part of the spray house body 1, preventing the powder sprayed by the spray gun 9 from splashing onto the powder blocking plate 8.

[0047] The air pipe 221 is connected to an air compressor, which blows air out of the air outlets 222 through the air pipe 221. The powder blocking plate 8 covers the top of the powder blocking body 2, preventing the powder from floating out of the top of the powder blocking body 2.

[0048] The air pipe 221 is arranged in multiple rows on the bottom of the powder blocking plate 8. The air pipe 221 is provided with a plurality of air outlets 222, so that the slight breeze blown out of the air outlets 222 covers the entire bottom of the powder blocking plate 8, preventing the powder from floating out of the top of the powder blocking body 2.

[0049] Further, the two sides of the powder blocking body 2 are provided with air inlet channels 5, one end of which is connected to the air inlet 10, and the other end of which is connected to the main exhaust barrel 4 and the auxiliary exhaust barrel 3.

[0050] The air inlet channel 5 is arranged at the acute angle of the two sides and the obtuse angle of the front side of the powder blocking body 2, which can correspond to the air inlet. The rolling down of the roller shutter belt 14 makes the plate blocks of the rear side and the front side of the powder blocking body 2 form an acute angle, and the plate blocks of the left and right sides of the front side of the powder blocking body 2 form an obtuse angle, so that the plate blocks of the powder blocking body 2 guide the airflow to the air inlet 10, and the airflow is sucked away by the main air suction barrel 4 and the auxiliary air suction barrel 3 through the air inlet channel 5, thereby avoiding the airflow remaining in the powder blocking body 2 and affecting the sprayed powder, so that the sprayed powder is not uniform.

[0051] As a preferred embodiment of the technical solution, the air inlet channel 5 comprises first air guide plates 51, a spacing block 52 and a fixing column 53; the two first air guide plates 51 are oppositely arranged, one end of the two first air guide plates 51 is connected to the two sides of the air inlet 10, and the other end of the two first air guide plates 51 is connected to the main air suction barrel 4 or the auxiliary air suction barrel 3; the spacing block 52 is arranged between the two first air guide plates 51, and the fixing column 53 passes through the two first air guide plates 51 to press the spacing block 52 against the side surface of the first air guide plate 51.

[0052] One end of the first air guide plate 51 is fixedly attached to the end surface of the powder blocking body 2, and the other end of the first air guide plate 51 is fixedly attached to the end surface of the main air suction barrel 4 or the auxiliary air suction barrel 3, so as to avoid the leakage of the airflow from the gap between the first air guide plate 51 and the end surface of the powder blocking body 2. The height of the first air guide plate 51 is consistent with the height of the powder blocking body 2, so that the air inlet amount of the air inlet 10 is consistent as a whole, which ensures that the airflow direction and speed in the spraying room are more stable, and improves the spraying effect. The spacing block 52 can separate the two first air guide plates 51 and make them parallel to each other, so as to facilitate the airflow to flow through the space between the two first air guide plates 51 and maintain a stable distance between the two first air guide plates. The fixing column 53 of the embodiment is a bolt, which is screwed into the two first air guide plates 51, so that the spacing block 52 is fixed between the two first air guide plates 51.

[0053] Further, the bottom air suction barrel 19 and the air suction channel 20 are further included, the bottom air suction barrel 19 is installed at the lower end of the air suction channel 20, the air suction channel 20 is connected to the bottom air suction barrel 19, and the end of the bottom air suction barrel 19 is connected to the auxiliary air suction barrel 3; the air inlet of the air suction channel 20 is located at the bottom of the internal space of the powder blocking body 2. The air suction channel 20 cooperates with the bottom air suction barrel 19 to suck the airflow at the bottom of the powder blocking body 2 into the air suction channel 20 and then through the auxiliary air suction barrel 3. The airflow is sucked into the bottom air suction barrel 19 from the air suction channel 20, and the bottom air suction barrel 19 connected to the auxiliary air suction barrel 3 sucks the airflow in the bottom air suction barrel 19, which better cooperates with the main air suction barrel 4 and the auxiliary air suction barrel 3 to reduce the airflow speed in the powder blocking body 2.

[0054] As a preferred embodiment of the technical solution, the air suction channel 20 comprises a second air deflector 201 and a connecting plate 202, the two connecting plates 202 are oppositely arranged, the bottom ends of the two connecting plates 202 are connected to the top of the bottom air suction barrel 19, the top ends of the two connecting plates 202 are respectively connected with the second air deflector 201, and the top of the two second air deflectors 201 forms the air inlet of the air suction channel 20. The air inlet facilitates the suction of air flow into the bottom air suction barrel 19. The upper end of the connecting plate 202 extends and fits on the end face of the connecting plate 202 in cooperation with the inclination angle of the second air deflector 201, and the lower end of the connecting plate 202 extends and fits on the surface of the bottom air suction barrel 19 in cooperation with the surface of the bottom air suction barrel 19, effectively preventing air flow from flowing out from the gap between the connecting plate 202 and the bottom air suction barrel 19, or from the gap between the connecting plate 202 and the second air deflector 201.

[0055] Further, the spray house body 1 is parallel to the powder blocking body 2. The parallel arrangement of the spray house body 1 and the powder blocking body 2 ensures that the distance between the inner side of the spray house body 1 and the outer side of the powder blocking body 2 is consistent, so that the powder blocking body 2 is installed at the center of the spray house body 1, and the auxiliary air suction barrel 3 installed at the sharp corners on both sides of the spray house body 1 and the main air suction barrel 4 installed at the obtuse corner in front of the spray house body 1 better cooperate with the air inlet 10 and the air suction channel 5 for air suction.

[0056] As a preferred embodiment of the technical solution, the spray house body 1 comprises two rear walls 1a and two front walls 1b; the connecting ends of the two front walls 1b are connected by a main wall 11, and the main wall 11 surrounds the main air suction barrel 4; the rear wall 1a and the front wall 1b are connected by an auxiliary wall 12, and the auxiliary air suction barrel 3 is located on the inner side of the auxiliary wall 12.

[0057] The two rear walls 1a, the main wall 11, the auxiliary wall 12 and the two front walls 1b form a rhombus in cross section, so that the inside of the spray house body 1 is wide enough to place workpieces and operate the spray gun 9, and the heights of the two rear walls 1a and the two front walls 1b are consistent to avoid external wind affecting the workpiece powder spraying and forming an internal space.

[0058] Since the main air suction barrel 4 and the auxiliary air suction barrel 3 have large volumes, the distance between the inner wall of the spray house body 1 and the outer wall of the powder blocking body 2 cannot meet the installation requirements of the main air suction barrel 4 and the auxiliary air suction barrel 3, so the main wall 11 and the auxiliary wall 12 are arranged at the positions of the main air suction barrel 4 and the auxiliary air suction barrel 3 respectively to expand the distance between the inner wall of the spray house body 1 and the outer wall of the powder blocking body 2, so as to facilitate the installation of the air suction barrels 4 and 3. The outer side of the main wall 11 and the auxiliary wall 12 is provided with a positioning block, and the end face of the positioning block is provided with a positioning hole, so that the spray house body 1 can be fixed to the ground through the positioning block to prevent the spray house body 1 from shaking.

[0059] Further, the top of the spraying room main body 1 is provided with a sliding bar 16 and a sliding block 17, the sliding bar 16 is located at the inner side of the powder blocking main body 2, the two ends of the sliding bar 16 are respectively arranged at the two sides of the feeding port 6, the sliding block 17 is slidingly installed at the lower end of the sliding bar 16, the lower end of the sliding block 17 is provided with a hook 18, the hook 18 can slide along the track of the sliding bar 16 at the lower end of the sliding bar 16 following the sliding block 17.

[0060] The sliding bar 16 is a cuboid, the sliding block 17 is a cube, the workpiece can be hung on the hook 18, the hook 18 can slide along the track 21 of the sliding bar 16 at the lower end of the sliding bar 16 following the sliding block 17, so as to move the position of the hook 18, and the workpiece is convenient to enter the powder blocking main body, and the spraying gun 9 can spray powder on the workpiece.

[0061] The two sides of the sliding bar 16 are provided with air pipes 221, the wind sprayed from the air pipes 221 can block the powder from floating upward into the sliding bar 16, so as to avoid affecting the cooperation of the sliding bar 16 and the sliding block 17.

[0062] Further, the feeding port 6 is provided with an elevator 7, and the spraying gun 9 is arranged at one end of the elevator 7, and the elevator 7 drives the spraying gun 9 to move.

[0063] The elevator 7 can drive the spraying gun 9 to reciprocate up and down at the feeding port 6, so as to facilitate the spraying gun 9 to spray powder.

[0064] When the elevator 7 drives the spraying gun 9 to reciprocate up and down to spray powder, the powder is caused to float upward and sink downward due to inertia, the auxiliary suction barrel 3, the main suction barrel 4 and the bottom suction barrel 19 can quickly recover when the powder floats upward and sinks downward, so as to prevent the powder from overflowing out of the spraying room main body 1 to cause waste and environmental pollution.
