Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing technology, and specifically discloses a paint spraying isolation room that facilitates the handling of board materials. Background Technology

[0002] A spray booth is a room or piece of equipment specifically designed for spray painting operations, aiming to provide a safe and efficient painting environment while minimizing the impact on operators and the surrounding environment. Spray booths are commonly used in automotive repair, industrial manufacturing, and architectural decoration.

[0003] For example, the utility model patent with authorization announcement number CN207546859U discloses an environmentally friendly dust-free spray painting booth. This environmentally friendly dust-free spray painting booth includes a main spray painting room with a door. The main spray painting room is assembled from well-sealed, insulated sandwich color steel panels. Inside the main spray painting room is a spray booth with a grid-patterned floor. A water curtain is installed in the spray booth. The upper part of the main spray painting room is a static pressure chamber, which is isolated from the spray booth by a filter ceiling. An air conditioning fan is installed in the static pressure chamber, connected to an air filtration chamber outside the main spray painting room. The air conditioning fan also provides airflow to the water curtain. A wastewater treatment chamber is connected under the grid-patterned floor. An exhaust vent is located at the bottom of the main spray painting room, connected to an exhaust duct and a waste gas treatment chamber. This utility model has a novel design and a simple, compact structure. It provides a highly environmentally friendly dust-free environment for furniture surface painting processes, ensuring the physical and mental health of operators. Currently, when painting furniture panels, some panels are too large to be painted by hand with a spray gun, resulting in uneven coating. Therefore, spraying is usually done in a spray booth using multiple spray heads. However, in conventional spray booths, panels are transported and painted from the same spray position, making continuous painting operations inconsistent. Furthermore, conventional panels are often positioned using complex clamping structures for stability during painting, requiring one panel to be painted before disassembling and placing the next, which is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a spray painting isolation room that facilitates the handling of board materials, so as to solve the problem of ensuring the stable handling of board materials when spraying multiple furniture boards continuously.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spray painting isolation room that facilitates the handling of sheet metal, comprising a spray painting outer room mechanism, wherein a spacing adjustment mechanism is provided inside the spray painting outer room mechanism, the spacing adjustment mechanisms are respectively arranged on both sides of the spray painting outer room mechanism, and a sheet metal conveying mechanism is provided between the spacing adjustment mechanisms distributed on both sides.

[0006] The paint spraying outer chamber mechanism has an inner paint spraying chamber mechanism located at its internal center, and the panel conveying mechanism passes through the inner paint spraying chamber mechanism.

[0007] Furthermore, the paint spraying chamber structure includes an outer room, the lower end of which is provided with a base. The outer room has a single-sided opening structure, with a door panel at the opening end. A handle lock is provided on the front of the door panel, and a transparent glass plate is provided through the upper part of the front of the door panel.

[0008] Furthermore, the spacing adjustment mechanism includes a side platform, the upper end of which is provided with a table surface, and the upper end of the table surface is provided with a bearing seat.

[0009] Furthermore, two bearing seats located on a single platform are internally connected by threaded rods. The threads on the surface of the threaded rods are distributed in two segments and are separated at the center along the length of the threaded rods. The two segments of the threads are symmetrical.

[0010] A motor is installed on one side above the table. Inside the motor is a drive shaft. The end of the shaft is fixedly connected to one end of a threaded rod via a coupling. The surface of the threaded rod is covered with a threaded sleeve, and the internal thread of the threaded sleeve and the external thread of the threaded rod are threadedly connected to each other.

[0011] Furthermore, the plate conveying mechanism includes a clamping plate, the surface of which penetrates the paint spraying chamber mechanism;

[0012] Several bearings are distributed on the inward side of the clamping plate, and a support shaft is installed through the inside of the bearing. A feeding guide sleeve is installed at the upper end of the support shaft.

[0013] Furthermore, a pulley is provided at the lower end of the support shaft, and several pulleys are connected by belt drive. A second motor is provided at the lower end of the support shaft at the far end. A second rotating shaft for driving is provided inside the second motor, and the end of the second rotating shaft is fixedly connected to the support shaft by a coupling.

[0014] Furthermore, a column is provided at the lower end of the clamping plate, and a roller is fixedly installed at the lower end of the column. The surface of the roller is in rolling contact with the upper surface of the base.

[0015] Furthermore, the spray painting chamber mechanism includes an inner room with openings on both sides, and each opening is equipped with a sealing plate with an internal hole inside.

[0016] Furthermore, a paint spraying pipe is installed through one side of the inner room. The paint spraying pipe has a branched structure, and the main interface of the paint spraying pipe is fixedly wrapped with a sleeve.

[0017] The two ends of the paint spraying pipe are forked and placed on the upper and lower sides of the feeding guide sleeve respectively. A pipe seat is fixed on the inner wall of the other side of the inner chamber, and the forked end of the paint spraying pipe is inserted into the pipe seat.

[0018] The forked part of the paint spray pipe is equipped with a paint spray head, and a solenoid valve is installed on the surface of the paint spray head.

[0019] A paint pump is installed on the outside of the inner room, and an extension plate is installed on the outer wall of the inner room. The lower end of the paint pump is fixed to the upper end of the extension plate through a bracket, and the discharge end of the paint pump is connected to the flange at the main interface of the paint spraying pipe.

[0020] The working principle and beneficial effects of this solution are as follows: 1. By setting up an outer spray painting chamber and an inner spray painting chamber, furniture panels can be doubly isolated from the outside world during spray painting, thereby further reducing the harm to the surrounding working environment during spray painting. When spraying panels, workers can enter the outer chamber to assist in loading and unloading the panels during continuous spray painting operations. After the panels are sent into the inner chamber, the upper and lower distributed spray head structure can simultaneously and evenly spray paint the upper and lower surfaces of the panels, thus achieving double-sided spray painting in a single pass.

[0021] 2. As described in 1, when the plate is conveyed into the inner room, it is mainly clamped and conveyed by the feeding guide sleeves on both sides. When the power of motor one is turned on, motor one can drive the threaded rod to rotate through the rotating shaft one, so that the two sections of the threaded rod with opposite directions can rotate at the same time, and the threaded sleeves distributed on the opposite threads can move. Through the distribution on both sides of the threaded rod and the clamping plate itself as a limiting structure, the threaded sleeves can drive the clamping plate to move inward, and make the clamping plates on both sides move in opposite directions or away from each other. Thus, the feeding guide sleeves distributed on both sides can be spaced according to the width of the plate to ensure stable clamping.

[0022] 3. As described in 2, in order to transport the panels, the power supply of motor two is turned on. Motor two can drive the support shaft to rotate through shaft two. The support shaft at the far end can be used as a drive shaft and drive the pulley on it to rotate. The pulley on the drive shaft can be used as a drive wheel. The remaining linked support shaft is the linkage shaft, and the pulley is the driven wheel. Through the rotation of the drive wheel, in conjunction with the belt, the rotation of several driven wheels can be realized. Thus, the synchronous rotation of several feeding guide sleeves can be realized, thereby realizing the stable transport of furniture panels for the painting interior mechanism.

[0023] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0034] The following detailed description illustrates the specific implementation method:

[0035] Example

[0036] like Figures 1 to 9 As shown, a paint spraying isolation room for easy loading and unloading of sheet metal is disclosed, including an outer paint spraying room mechanism 1, a spacing adjustment mechanism 2 is provided inside the outer paint spraying room mechanism 1, the spacing adjustment mechanisms 2 are respectively provided on both sides of the outer paint spraying room mechanism 1, a sheet metal conveying mechanism 3 is provided between the spacing adjustment mechanisms 2 distributed on both sides, and an inner paint spraying room mechanism 4 is provided at the center of the outer paint spraying room mechanism 1, and the sheet metal conveying mechanism 3 is provided through the inner paint spraying room mechanism 4.

[0037] The paint spraying chamber mechanism 1 includes an outer chamber 10. A base 11 is located at the lower end of the outer chamber 10. The edge of the base 11 is fixed to the bottom of the outer chamber 10 with screws. The outer chamber 10 has a single-sided opening structure, with a door panel 12 at the opening. The door panel 12 is a double-door structure, and one end of the door panel 12 is hinged to the opening position of the outer chamber 10. A handle lock 13 is located on the front of the door panel 12. The lock cylinder of the handle lock 13 is embedded inside the door panel 12. The handle lock 13 can be used to lock the double-door door panel 12 after it is closed. The door lock is a rotary type, which is simple and convenient to operate. A transparent glass plate 14 is installed through the upper part of the front of the door panel 12. The transparent glass plate 14 serves as a peeping function. The edge of the transparent glass plate 14 is fixed to the door panel 12 with screws, and the joint between the transparent glass plate 14 and the door panel 12 is filled with sealant. The transparent glass plate 14 is made of tempered glass, which can ensure sufficient strength and safety during use. A fresh air system can also be embedded in the closed end of the outer room 10 to assist in exhaust and air purification. The installation and setting should be carried out according to actual needs.

[0038] The spacing adjustment mechanism 2 includes a side platform 20. The lower end of the side platform 20 is fixedly assembled with the upper end of the base 11 by screws. The upper end of the side platform 20 is provided with a table surface 21. The lower end of the table surface 21 is fixedly connected to the side platform 20 by welding. The upper end of the table surface 21 is provided with a bearing seat 22. The bearing seats 22 are symmetrically distributed along the longitudinal position of the table surface 21. The lower end of the outer wall of the bearing seat 22 is fixedly assembled with the upper end of the table surface 21 by a bracket. The cooperation between the side platform 20 and the table surface 21 can ensure the stable support of the spacing adjustment mechanism 2 during use.

[0039] Two bearing seats 22 distributed on a single platform 21 are internally provided with threaded rods 23. The surface of the threaded rod 23 is rotatably sleeved with the inner wall of the bearing seat 22. The thread on the surface of the threaded rod 23 is distributed in two segments and is separated along the center of the length of the threaded rod 23. The two-segment thread is symmetrical, which allows the moving parts that cooperate with the threaded rod 23 to move closer or further away from each other when rotating, thereby meeting the movement and cooperation requirements of the plate size.

[0040] A motor 24 is also installed on one side above the platform 21. The lower end of the outer wall of the motor 24 is fixedly assembled to the upper end of the platform 21 through a bracket. The motor 24 has a drive shaft inside. The end of the drive shaft is fixedly connected to one end of the threaded rod 23 through a coupling. After the motor 24 is powered on, it can drive the threaded rod 23 through the drive shaft, thereby ensuring that the thread on the surface of the threaded rod 23 can rotate stably. The surface of the threaded rod 23 is covered with a threaded sleeve 25. The inner thread of the threaded sleeve 25 and the outer thread of the threaded rod 23 are threadedly connected to each other. The outer ring wall of the threaded sleeve 25 is rectangular, which can be easily connected to the plate conveying mechanism 3. There are two threaded sleeves 25 on a single threaded rod 23, which are located on two symmetrically distributed threads. When driving, the two threaded sleeves 25 can move in opposite directions.

[0041] The plate conveying mechanism 3 includes a clamping plate 30, the surface of which penetrates the spray painting chamber mechanism 4. The two ends of the clamping plate 30 are fixedly connected to the corresponding threaded sleeves 25 by a bracket. There are two clamping plates 30, which are symmetrically distributed and can move on the threaded rod 23 by the corresponding threaded sleeves 25, so that the two clamping plates 30 can move in opposite directions.

[0042] Several bearings 31 are distributed on the inward side of the clamping plate 30. Adjacent bearings 31 are equidistantly distributed. The outer ring wall of the bearing 31 is fixedly assembled to the surface of the clamping plate 30 through the bracket. A support shaft 32 is installed through the inside of the bearing 31. The surface of the support shaft 32 is interference-fitted with the inner ring wall of the bearing 31. A feeding guide sleeve 33 is provided at the upper end of the support shaft 32. The feeding guide sleeve 33 is fixedly sleeved to the surface of the support shaft 32. The feeding guide sleeve 33 is made of rubber material, and the lower end of the feeding guide sleeve 33 has a wide opening structure. The feeding guide sleeves 33 located opposite each other can contact and clamp the plate. Through the deformation effect of the rubber material and sufficient damping effect, the clamping stability can be ensured. The wide opening structure at the lower end also plays an auxiliary role in preventing falls.

[0043] A pulley 34 is provided at the lower end of the support shaft 32. The connection between the pulley 34 and the support shaft 32 is fixed by screws. Several pulleys 34 are connected by a belt 35. A motor 36 is provided at the lower end of the support shaft 32 at the far end. The outer wall of the motor 36 is fixedly assembled to the lower end of the clamping plate 30 by a bracket. A rotating shaft 2 for driving is provided inside the motor 36. The end of the rotating shaft 2 is fixedly connected to the support shaft 32 by a coupling. Driven by the motor 36, the rotating shaft 2 can drive the support shaft 32 to rotate, so that the current pulley 34 can be used as the driving wheel and the other pulleys 34 can be used as the driven wheel. Through the transmission effect of the belt 35, the driving wheel and the driven wheel can rotate simultaneously, which can realize the linkage of the feeding guide sleeve 33. In addition, the feeding guide sleeves 33 on both sides can move the plate in and out by rotating themselves after clamping the plate.

[0044] A column 3001 is provided at the lower end of the clamping plate 30. The column 3001 is located outside the paint spraying chamber mechanism 4. The upper end of the column 3001 is fixed to the clamping plate 30 with screws. The columns 3001 are distributed on the clamping plate 30 and are symmetrically distributed on both sides of the paint spraying chamber mechanism 4. A roller 3002 is fixedly installed at the lower end of the column 3001. The surface of the roller 3002 is in rolling contact with the upper end surface of the base 11. The arrangement of the column 3001 and the roller 3002 can provide anti-bending support for the clamping plate 30 with a large span, reduce the length of the central part, and thus improve the deformation resistance of the clamping plate 30. The roller 3002 is a universal wheel, which can move and support in the opposite direction according to the movement of the clamping plate 30.

[0045] The spray painting chamber mechanism 4 includes an inner chamber 40, which is located on the upper end of the base 11. The lower edge of the inner chamber 40 is fixedly assembled to the surface of the base 11 by screws. The inner chamber 40 has an opening structure on both sides, and a sealing plate 41 is provided at each opening. The edge of the sealing plate 41 is fixed to the end face of the inner chamber 40 by screws. An internal hole 42 is provided inside the sealing plate 41, which is connected to the clamping plate 30. The internal hole 42 can ensure that the plates can pass through normally when being transported in and out of the inner chamber 40. During spray painting, the inner chamber 40 can serve as the first layer of protection to prevent paint from overflowing into the outer chamber 10.

[0046] A paint spraying pipe 401 is installed through one side of the inner chamber 40. The paint spraying pipe 401 has a forked structure, and a pipe sleeve 405 is fixedly wrapped around the main interface of the paint spraying pipe 401. The pipe sleeve 405 is installed through and fitted into the inner chamber 40, and the connection between the pipe sleeve 405 and the inner chamber 40 is fixed by screws. The two forked ends of the paint spraying pipe 401 are distributed on the upper and lower sides of the feeding guide sleeve 33, and the forked parts are symmetrically arranged. A pipe seat 402 is fixed on the inner wall of the other side of the inner chamber 40. The forked end of the paint spraying pipe 401 is inserted into the pipe seat 402, and the forked end of the paint spraying pipe 401 is closed. The spray nozzle 403 is installed through the bifurcation of the spray pipe 401. The spray nozzles 403 are symmetrically arranged vertically. The connection between the spray nozzle 403 and the spray pipe 401 is welded and fixed. The surface of the spray nozzle 403 is provided with a solenoid valve 404. The valve core of the solenoid valve 404 is embedded and fixed inside the spray nozzle 403. Paint can be delivered through the spray pipe 401 and the spray nozzle 403 can be used for painting the board. The solenoid valve 404 is installed one-to-one with the spray nozzle 403. The opening and closing of the spray nozzle 403 can be selected according to the width of the board, thereby achieving the effect of saving paint.

[0047] A paint pump 407 is installed outside the inner room 40, and an extension plate 406 is installed on the outer wall of the inner room 40. One end of the extension plate 406 is fixed to the outer wall of the inner room 40 by screws. The lower end of the paint pump 407 is fixed to the upper end of the extension plate 406 by a bracket. The paint pump 407 can pump and deliver paint materials to ensure stable feeding pressure during painting. The discharge end of the paint pump 407 is connected to the flange at the main interface of the paint spray pipe 401 to ensure stable feeding of paint to the paint spray pipe 401 during painting.

[0048] In practice

[0049] When it is necessary to spray paint furniture panels, first open the door panel 12 of the outer room 10, send the panels to be processed into the outer room 10 to wait for processing, and close the door panel 12. The outer room 10 can isolate and protect the surrounding working environment during spray painting. The cooperation between the outer room 10 and the inner room 40 allows the inner room 40 to be used as an isolation structure based on the interior of the outer room 10 when continuous processing of the panels is required. This ensures that workers can work in the outer room 10, and the isolation of the inner room 40 can reduce the spillage and splashing of paint materials onto workers during the spray painting process.

[0050] When clamping the plate is required, the power supply of motor 24 is turned on. Motor 24 and motor 36 are respectively connected to a forward and reverse switch via wires. The forward and reverse switch can adjust the forward and reverse rotation of the motor. When the power supply of motor 24 is turned on, motor 24 can drive the threaded rod 23 to rotate through the rotating shaft 1, so that the two sections of the threaded rod 23 in the forward and reverse directions can rotate simultaneously, and the threaded sleeves 25 distributed on the forward and reverse threads can move. Through the distribution on both sides of the threaded rod 23 and the clamping plate 30 itself as a limiting structure, the threaded sleeves 25 can drive the clamping plate 30 to move inward, and make the two clamping plates 30 on both sides move in opposite directions or move away from each other. Thus, the spacing of the feeding guide sleeves 33 distributed on both sides can be adjusted according to the width of the plate to ensure clamping stability. When the clamping plate 30 moves, the auxiliary cooperation of the column 3001 and the roller 3002 can ensure that the clamping plate 30 will not deform due to long-term repeated use when the feeding guide sleeves 33 clamp the plate to bear the load.

[0051] In order to transport the panels, the power supply of motor 2 36 is turned on. Motor 2 36 can drive the support shaft 32 to rotate through the rotating shaft 2. The support shaft 32 at the end can be used as a drive shaft and drive the pulley 34 on it to rotate. The pulley 34 on the drive shaft can be used as a drive wheel. The remaining linked support shaft 32 is the linkage shaft, and the pulley 34 is the driven wheel. Through the rotation of the drive wheel, in conjunction with the belt 35, the rotation of several driven wheels can be realized. Thus, the synchronous rotation of several feeding guide sleeves 33 can be realized, thereby realizing the stable transport of furniture panels for the painting inner room mechanism 4.

[0052] During spraying, the power supply to the paint pump 407 is turned on, allowing the paint pump 407 to pump paint into the spray pipe 401, and then spray it evenly onto the board through the spray head 403. The vertically distributed spray head 403 structure can achieve vertical spraying of the board. According to the clamping and positioning width of the board, the use and closure of the spray head 403 can be controlled by the opening and closing of the solenoid valve 404, thereby achieving the effect of saving paint.

[0053] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
