Description

Technical Field

[0001] The invention relates to the field of spraying, and in particular to a hoisting device and a hoisting transportation line for spraying plates. Background Art

[0002] The boards used for furniture often need to be painted on their surface. Painting can protect the boards. Painting is equivalent to putting a layer of armor on the furniture, protecting the wood from damage and maintaining its original texture and beauty. Painting can also enhance the beauty of furniture, prevent deformation of the boards and increase their service life.

[0003] Since the plates used for furniture assembly generally have installation holes, such as screw holes, etc., the most common plate hangers currently use hooks to directly cooperate with the installation holes to suspend the plates, and can also cooperate with existing slide rails to achieve lifting and transportation. In the process of hanging the plates, generally only one end of the plate is hooked so that it can be lifted and transported through the existing slide rails. However, the plates used for large furniture are larger in size. If the plates are kept vertical during transportation, it is difficult to arrange other devices in the lower space of the factory, and the space utilization rate is low. If the two ends of the plate are hung by hooks, it is difficult to achieve the inclined setting of the transportation line. For example, when the plate needs to be transported from the lower floor to the upper floor in a multi-story factory building, if one end of the plate travels on the horizontal transportation line and the other end of the plate travels on the inclined transportation line, the speeds of the two ends of the plate in the horizontal direction are not consistent, and jamming may occur during transportation.

DETAILED DESCRIPTION

[0035] In order to make the purpose, method scheme and advantages of the embodiments of the present invention clearer, the method scheme in the embodiments of the present invention is clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] The boards used for furniture often need to be painted on their surface. Painting can protect the boards. Painting is equivalent to putting a layer of armor on the furniture, protecting the wood from damage and maintaining its original texture and beauty. Painting can also enhance the beauty of furniture, prevent deformation of the boards and increase their service life.

[0037] Since the plates used for furniture generally have mounting holes, such as screw holes, etc., the currently common plate hangers directly use hooks to cooperate with the mounting holes to hang the plates, and can also cooperate with existing slide rails to achieve lifting and transportation. In the process of hanging the plates, generally only one end of the plate is hooked so that lifting and transportation can be achieved through the existing slide rails. However, the plates used for large furniture are larger in size. If the plates are kept in a vertical state during transportation, it is difficult to arrange other devices in the lower space of the factory area, and the space utilization rate is low. If the two ends of the plate are hung by hooks, it is difficult to achieve the inclined setting of the transportation line. For example, when the plate needs to be transported from the lower floor to the upper floor in a multi-story factory building, if one end of the plate travels on a horizontal transportation line and the other end of the plate travels on an inclined transportation line, the speeds of the two ends of the plate in the horizontal direction are not consistent, and jamming may occur during transportation. Therefore, the applicant hopes to design a hanger that can solve the aforementioned problems and realize the multi-scenario application of the hanger, as shown in the following embodiments.

[0038] Example 1: Figure 1-3As shown, a lifting device for plate spraying includes a trolley 1, a telescopic rod 2, a first moving belt 3, a second moving belt 4, a gear 5, a transmission steering assembly 6 and a hook 8: the trolley 1 is provided with an upper transverse hole 101, a through hole 103 and a lower transverse hole 102, the upper transverse hole 101 is connected with the lower transverse hole 102 through the through hole 103, and the bottom end of the trolley 1 is provided with a mounting hole 104 connected with the lower transverse hole 102; the top wall of the upper transverse hole 101 is provided with a telescopic rod 2, and one side of the telescopic rod 2 is provided with a rack 201; the first moving belt 3 is passed through the upper transverse hole 101, the second moving belt 4 is passed through the gear 5, a transmission steering assembly 6 and a hook 8; A moving belt 3 is provided with a first socket 301 cooperating with the telescopic rod 2, and the first socket 301 is connected to the top of the through hole 103; the second moving belt 4 is passed through the lower horizontal hole 102, and the second moving belt 4 is provided with a second socket 401 cooperating with the telescopic rod 2; the gear 5 is provided in the mounting hole 104 and can be engaged with the rack 201; the gear 5 is connected to one end of the transmission steering assembly 6; the hook 8 is connected to the other end of the transmission steering assembly 6 through a rotating shaft 801, and the central axis of the rotating shaft 801 is perpendicular to the meshing surface of the rack 201.

[0039] In the specific implementation process, a telescopic cylinder can be arranged on the top of the traveling crane 1, and the output shaft of the telescopic cylinder passes through the top wall of the traveling crane 1 and is connected to the telescopic rod 2, thereby realizing the telescopic rod 2. The telescopic rod 2, the first plug hole 301 and the second plug hole 401 can be as shown in FIG. Figure 1-2 As shown, two are provided, and a distance sensor, such as an infrared distance measuring sensor, can be provided at the end of the telescopic rod 2 to ensure that the telescopic rod 2 is aligned with the first socket 301 and the second socket 401. If the telescopic rod 2 is misaligned with the first socket 301 or the second socket 401, the infrared light will be blocked by the first moving belt 3 or the second moving belt 4, and the value detected by the distance sensor will become smaller. The upper transverse hole 101 and the lower transverse hole 102 both extend along the traveling direction of the vehicle 1 and pass through the vehicle 1. The driving mode of the first moving belt 3 and the second moving belt 4 is the prior art, and different driving modes are available in different application scenarios. An elastic layer, such as a rubber layer and a silicone layer, can be provided in the first socket 301 and the second socket 401. When the telescopic rod 2 is inserted, the elastic layer abuts against the side wall of the telescopic rod 2, and the elastic layer can reduce the lateral movement of the telescopic rod 2 in the first socket 301 or the second socket 401.

[0040] In this embodiment, when the sling is used, the hanging method of the plate 19 can be selected according to the actual situation. For example, when the width of the plate 19 is narrow and the length is large, reference can be made to Figure 6 As shown, the plate 19 is hung on one side in the width direction, using two hangers. When the length and width of the plate 19 are both large, you can refer to Figure 5As shown, hangers are respectively arranged at the four corners of the plate 19, and the two hangers opposite to the hook 8 share the first moving belt 3 and the second moving belt 4. When the plate 19 is loaded, a support platform can be arranged below it. It should be noted that the support platform will not block the hole for hanging on the plate 19. At the same time, the height of the first moving belt 3 and the second moving belt 4 is relatively low, and the initial height of the hook 8 is close to the upper surface of the plate 19, so that the loading operation can be completed simply.

[0041] The sling provided in this embodiment can be used in a variety of scenarios, as follows:

[0042] For example, when the sling in this embodiment is used for transporting the plate 19, the first moving belt 3 and the second moving belt 4 can refer to Fig.14 As shown in the figure, a winding roller is provided, and the rotation of the winding roller drives the movement of the first moving belt 3 or the second moving belt 4. When the plate 19 is transported horizontally, there are at least the following two implementation methods:

[0043] The first one can refer to Figure 7 As shown, the telescopic rod 2 on the sling passes through the first hole 301 and the second hole 401, but the rack 201 on the telescopic rod 2 does not mesh with the gear 5. The hook 8 has a certain degree of rotational freedom, but under the action of the gravity of the plate 19, it is mainly in a vertical state.

[0044] The second reference Figure 8 As shown, after the telescopic rod 2 on the sling passes through the first socket 301 and the second socket 401, the rack 201 on the telescopic rod 2 engages with the gear 5. At this time, the hook 8 remains vertical and locked, and the hook 8 has no free movement, so the transportation process of the plate 19 is smoother.

[0045] When the spreader passes Figure 3 When the bending path is shown, the front spreader is on the inclined conveyor line and the rear spreader is on the horizontal conveyor line. Figure 7 As shown, the hooks 8 of the front and rear slings are not locked, and the slings can move smoothly. Figure 8 As shown, after the hooks 8 of the front and rear slings are locked, since the two slings share the first moving belt 3 and the second moving belt 4, their speeds in the horizontal direction are inconsistent, which may cause jamming. There are at least the following two solutions.

[0046] The first one can refer to Fig. 9As shown, the telescopic rod 2 of the sling located on the inclined transport line is shortened a part, so that the rack 201 is disengaged from the gear 5, but not disengaged from the first socket 301 and the second socket 401, and the first moving belt 3 and the second moving belt 4 can still move the carriage 1, and the hook 8 has rotational freedom. After the rack 201 is disengaged, the hook 8 rotates under the gravity of the plate 19 and maintains a vertical state, and the telescopic rod 2 of the sling on the horizontal transport line is completely disengaged from the first socket 301 and the second socket 401, and the hook 8 on the sling also has rotational freedom. The carriage 1 on the inclined transport line drives the plate 19, and the plate 19 drives the carriage 1 on the horizontal transport line to move. Since the hook 8 has rotational freedom, movement jamming will not occur.

[0047] The second reference Fig.10 As shown, the rack 201 of the sling located on the inclined transport line is still meshed with the gear 5, and the hook 8 is locked. The telescopic rod 2 of the sling located on the horizontal transport line is completely disengaged from the first socket 301 and the second socket 401, and the hook 8 has the freedom of rotation. The crane 1 on the inclined transport line drives the plate 19, and the plate 19 drives the crane 1 on the horizontal transport line to move. Since the hook 8 has the freedom of rotation, the movement jamming phenomenon will not occur. The advantage of using the second method is that the transportation of the plate 19 is more stable; if the sling passes through the inclined transport line and still returns to the horizontal transport line, the hook 8 of the front sling can be directly locked in a vertical state. When the first method is used, if you want to lock it, you need to extend the telescopic rod 2 so that the rack 201 is meshed with the gear 5 again. During the meshing process, the hook 8 will rotate under the drive of the gear 5, and the plate 19 will deflect.

[0048] For example, when the hanger in this embodiment is used for hanging the plate 19 when spraying, there are two main spraying methods for the plate 19 used for furniture. One is to spray the inner and outer surfaces of the plate 19. At this time, the hanging method of the plate 19 can refer to Figure 6 As shown, the inner and outer surfaces are fully exposed. If there are concave-convex structures on the surface, such as carvings, in order to fully spray the concave-convex structures, the first moving belt 3 and the second moving belt 4 can be relatively displaced when the hooks 8 of the two lifting devices are locked, so that the trolley 1 is deflected, and then the angle of the plate 19 is adjusted by the change of the angle of the trolley 1. The displacement of the first moving belt 3 and the second moving belt 4 can refer to Fig.14 As shown, winding rollers are arranged at both ends of the moving belt, and the movement of the moving belt is realized by the rotation of the winding rollers; the other is to spray the outer surface of the plate 19 and paste the film on the inner surface. At this time, the hanging method of the plate 19 can be as follows Figure 5 As shown, the outer surface of the plate 19 faces downward, and the rack 201 on the telescopic rod 2 can drive the hook 8 to rotate, thereby achieving a change in the angle of the plate 19.

[0049] Embodiment 2: This embodiment provides an implementation of a transmission steering assembly 6, such as Figure 4 As shown, in this embodiment, the transmission steering assembly 6 includes: a first bevel gear 601, a second bevel gear 602 and a third bevel gear 603; the first bevel gear 601 is coaxially connected to the gear 5; the second bevel gear 602 is meshed with the first bevel gear 601; the third bevel gear 603 is meshed with the second bevel gear 602, and the third bevel gear 603 is connected to the rotating shaft 801.

[0050] In the specific implementation process, the gear 5 and the second bevel gear 602 can be rotatably connected to the inner wall of the crane 1. If two telescopic rods 2 are provided in the sling, Figure 4 As shown, the third bevel gears 603 corresponding to the two telescopic rods 2 are arranged relatively to each other so that the two third bevel gears 603 rotate in the same direction. When both telescopic rods 2 move upward, the left gear 5 rotates clockwise, driving the second bevel gear 602, and the second bevel gear 602 drives the third bevel gear 603 to rotate in the direction of the arrow shown in the figure. The right gear 5 rotates counterclockwise, also driving the second bevel gear 602, and the second bevel gear 602 drives the third bevel gear 603 to rotate in the direction of the arrow shown in the figure. At this time, the third bevel gears 603 on both sides rotate in the same direction, and the two third bevel gears 603 are connected to the upper end of the hook 8 through the rotating shaft 801, thereby driving the hook 8 to rotate.

[0051] Embodiment 3: In order to reduce the friction of the vehicle 1 moving along the first moving belt 3 and the second moving belt 4, an improvement is made on the basis of Embodiment 2, such as Figure 1 As shown, in this embodiment, it also includes: a first roller 9 and a second roller 10; the upper horizontal hole 101 is provided with a first roller 9, and the first roller 9 abuts against the upper wall of the first moving belt 3; the lower horizontal hole 102 is provided with a second roller 10, and the second roller 10 abuts against the upper wall of the second moving belt 4.

[0052] In the specific implementation process, when one of the slings responsible for transporting the unified plate 19 is located on the inclined transport line and the other is located on the horizontal transport line, the trolley 1 on the inclined transport line pulls the trolley 1 on the horizontal transport line to move along the surface of the first moving belt 3 and the second moving belt 4. In order to reduce the friction during movement, Figure 1 The first roller 9 and the second roller 10 are shown, and rollers may also be provided on both the upper and lower sides of the moving belt.

[0053] Since the distance between the front and rear trolleys 1 is determined by the specifications of the plate 19, when the hoist needs to hoist plates 19 of different specifications, the distance between the front and rear trolleys 1 needs to be adjusted. Although at this time, the telescopic rod 2 of one trolley 1 can be extended into the first socket 301 and the second socket 401, the trolley 1 can move with the moving belt, while the telescopic rod 2 of the other trolley 1 is separated from the first socket 301 and the second socket 401, thereby the distance between the two trolleys 1 can be changed by the movement of the moving belt, but the operation is relatively cumbersome. For example, the positioning of the telescopic rod 2 in the other trolley 1 when reinserted into the socket, and for another example, although the telescopic rod 2 in the trolley 1 does not extend into the first socket 301 and the second socket 401, the friction between the trolley 1 and the moving belt may also drive the trolley 1 to move a certain distance, and the distance adjustment is unstable. Therefore, a driving mechanism can be selected or all of the first roller 9 and the second roller 10 to enable the sling to move autonomously on the moving belt, thereby facilitating the hoisting of plates 19 of different specifications.

[0054] Example 4: Figure 2 As shown, in this embodiment, the upper transverse hole 101 and the lower transverse hole 102 both include: a receiving hole 1011 and a giving way hole 1012; the receiving hole 1011 is used to place the first moving belt 3 or the second moving belt 4; the giving way hole 1012 is connected to the upper end of the receiving hole 1011, and the giving way hole 1012 is used for the passage of the turning member 7 on the transport line.

[0055] In the specific implementation process, the cross-section of the upper transverse hole 101 and the lower transverse hole 102 can be a convex shape. Figure 2 As shown, it passes through the receiving hole 1011. Figure 3 As shown, the first moving belt 3 and the second moving belt 4 need a steering member 7, and the steering member 7 can be set at the inflection point. The steering member 7 can be a tension roller, which is used to keep the moving belt taut and reduce the friction between the moving belt and the steering member 7 by self-rotation. Due to the existence of the steering member 7, the present embodiment is provided with a clearance hole 1012, which increases the span of the upper horizontal hole 101 and the lower horizontal hole 102 in the vertical direction, so that the steering member 7 can smoothly pass between the two telescopic rods 2. If the steering member 7 is located below the moving belt, then Figure 2 As shown, the space below the first moving belt 3 and the mounting hole 104 below the second moving belt 4 pass through.

[0056] Example 5: Figure 3 As shown, in this embodiment, the hook 8 includes: a first telescopic section 802 and a hook-shaped section 803 ; the top end of the first telescopic section 802 is connected to the rotating shaft 801 ; one end of the hook-shaped section 803 is connected to the bottom end of the first telescopic section 802 .

[0057] In the specific implementation process, the first telescopic section 802 can be an electric telescopic rod. When loading, the hook 8 can be moved to the bottom of the hanging hole of the plate 19 through the first telescopic section 802, and then the first telescopic section 802 is shortened to allow the hook 8 to enter the hanging hole. When loading, the hook 8 is locked through the cooperation of the rack 201 and the gear 5 to prevent it from shaking and affecting the hooking of the plate 19. In addition, the height difference between the two ends of the plate 19 can be adjusted by the extension and contraction of the first telescopic section 802.

[0058] Embodiment 6: In order to ensure the hoisting stability of the plate 19 while facilitating the hanging of the plate 19, an improvement is made on the basis of Embodiment 5, such as Figure 3 As shown, in this embodiment, the hook 8 further includes: a second telescopic section 804 , the bottom end of which is connected to an end of the hook-shaped section 803 away from the first telescopic section 802 .

[0059] In the specific implementation process, the second telescopic section 804 can be an electric telescopic rod. Before the plate 19 is hung, the second telescopic section 804 is in a shortened state, so that the free end of the second telescopic section 804 can smoothly enter the hanging hole of the plate 19. After the free end of the second telescopic section 804 enters the hanging hole of the plate 19, the second telescopic section 804 extends, and the free end of the second telescopic section 804 passes through the hanging hole.

[0060] During unloading, the second telescopic section 804 contracts to reduce the accommodation length of the second telescopic section 804 in the hanging hole of the plate 19, and then the rack 201 is moved to drive the hook 8 to rotate, so that the free end of the second telescopic section 804 is disengaged from the hanging hole, and finally the first telescopic section 802 is contracted to achieve complete separation of the hook 8 from the plate 19. If the accommodation length of the free end of the second telescopic section 804 in the hanging hole is large when the hook 8 rotates, the hook 8 is easily obstructed by the hanging hole when it rotates out, and reducing the length of the insertion end of the hook 8 will reduce the lifting stability of the plate 19. Therefore, the second telescopic section 804 is provided in this embodiment, which not only makes the loading and unloading operations of the plate 19 simpler and more convenient, but also improves the lifting stability of the plate 19.

[0061] Embodiment 7: This embodiment provides a lifting and transportation line, including: the lifting device for plate spraying; the first moving belt 3 and the second moving belt 4 are arranged in parallel up and down to form a transportation group; the transportation group includes at least one horizontal transportation section and one inclined transportation section; every two adjacent vehicles 1 on the transportation group are a lifting group 11, and the vehicles 1 in the lifting group 11 are respectively a driving vehicle 1101 and a driven vehicle 1102; in the moving direction of the transportation group, the driving vehicle 1101 is located at the front end of the driven vehicle 1102; when the driving vehicle 1101 in the lifting group 11 is located in the inclined transportation section and the driven vehicle 1102 is located in the horizontal transportation section, the free end of the telescopic rod 2 in the driven vehicle 1102 is located above the first moving belt 3.

[0062] In the specific implementation process, the first moving belt 3 and the second moving belt 4 are arranged in parallel up and down. Figure 3 As shown, the two moving belts together constitute the driving source of the traveling vehicle 1. When the driving vehicle 1101 in the hoisting group 11 is located in the inclined transport section, and the driven vehicle 1102 is moved to the horizontal transport section, it can be referred to Fig. 9 or Fig.10 As shown, the telescopic rod 2 on the driven vehicle 1102 is completely separated from the first plug hole 301 and the second plug hole 401, and the driven vehicle 1102 is dragged forward by the driving vehicle 1101. When the driving vehicle 1101 and the driven vehicle 1102 are both located in the inclined transport section, the telescopic rod 2 in the driven vehicle 1102 can be inserted into the first plug hole 301 and the second plug hole 401 again to improve the hoisting stability of the plate 19. If the distance of the inclined transport section is very short, when the driving vehicle 1101 and the driven vehicle 1102 are both located in the inclined transport section, the telescopic rod 2 in the driven vehicle 1102 can also be kept separated from the moving belt, because in the process of the hoisting device from the inclined transport section to the horizontal transport section, the telescopic rod 2 in the driven vehicle 1102 also needs to be separated from the moving belt.

[0063] Embodiment 8: In order to combine the transportation process with the spraying, improvements are made on the basis of Embodiment 7, such as Fig.11 or Fig.12 As shown, in this embodiment, the inclined transport section includes: a first spraying section 12 and a second spraying section 13, the first spraying section 12 is inclined upward or downward along the traveling direction of the carriage 1, and the second spraying section 13 is inclined in the opposite direction to the first spraying section 12; the hoisting transport line also includes: a first spraying area and a second spraying area; the first spraying area covers part of the first spraying section 12; the second spraying area covers part of the second spraying section 13; when the carriage 1 completely leaves the second spraying area with the plate 19, the bottom wall of the plate 19 is in a horizontal state.

[0064] In the specific implementation process, a spray head is set below the first spray section 12 and the second spray section 13, and the spray head does not move, and the plate 19 passes over the spray head to achieve spraying. The hoisting method of the plate 19 can refer to Figure 5 As shown, the outer surface of the plate 19 to be sprayed faces downward. Fig.10 or Fig.11 As shown, the spraying area formed by the spray of the nozzle only covers a part of the spraying section. If the width of the plate 19 is large, multiple nozzles can be arranged along the width direction of the plate 19.

[0065] The advantage of this embodiment of spraying in the inclined transport section is that if the outer surface of the plate 19 is not smooth and has a concave-convex layer 191, and the spray head sprays perpendicularly to the outer surface of the plate 19, the spraying of the concave-convex layer 191 is prone to dead corners. This embodiment directly uses the angle change of the plate 19 brought about by the inclined transport section to achieve full spraying of the side wall of the concave-convex layer 191. In addition, Figure 5 In the hoisting mode, the first telescopic section 802 on the hook 8 can be extended and retracted to achieve the displacement of the plate 19 in the width direction, and the rack 201 can also be used to drive the hook 8 to rotate to achieve the displacement of the plate 19 in the width direction, thereby further improving the overall spraying rate of the plate 19.

[0066] Furthermore, if the length of the first spraying section 12 or the second spraying section 13 is relatively long, the sprayed surface of the plate 19 will remain tilted for a long time after spraying, which is not conducive to the leveling of the paint. Therefore, after the spraying is completed, the sprayed surface of the plate 19 can be adjusted to a horizontal state by extending the first telescopic section 802. For example, the higher end of the plate 19 can be lowered by extending the first telescopic section 802, or the lower end of the plate 19 can be raised by shortening the first telescopic section 802. Of course, the first telescopic section 802 can also be used to raise the lower end of the plate 19 while lowering the higher end of the plate 19.

[0067] In this embodiment, the first spraying section 12 can be Fig.11 The first spraying section 12 may also be as shown in FIG. Fig.12 The second spraying section 13 is set as the ascending section. It can be set automatically according to the layout of the factory. The spraying section can be set with a channel consisting of two side panels and a top panel, and the hanger and the plate 19 pass through the channel, and the nozzle is set at the bottom of the channel. The channel can prevent the paint from contaminating other locations in the factory during spraying.

[0068] Embodiment 9: In order to prevent the paint from flowing randomly or even dripping after spraying, improvements are made on the basis of Embodiment 8, such as Fig.11 or Fig.12As shown, in this embodiment, the horizontal transport section includes: a drying section 14, and the second spraying section 13 is connected to the drying section 14; when the active vehicle 1101 in the same lifting group 11 is located in the drying section 14 and the driven vehicle 1102 is located in the second spraying section 13, the free end of the telescopic rod 2 in the driven vehicle 1102 is located above the first moving belt 3.

[0069] In the specific implementation process, the drying section 14 can be provided with a channel consisting of four side panels and a top panel, and the channel leaves an opening for the hanger and the plate 19 to pass through. A heating device, such as a heating plate or a hot air blower, can be provided in the channel to initially solidify the coating through heat transfer to prevent it from dripping during transportation or the coating from flowing due to the shaking of the plate 19, which affects the uniformity of the coating. If a hot air blower is used, it should be noted that the wind speed should not be too high to avoid its impact on the coating. After the initial drying in the drying section 14, the plate 19 is sent to the drying room through the hanger.

[0070] Embodiment 10: In order to further optimize the layout of the plant transport line and reduce the number of inclined transport sections as much as possible, improvements are made on the basis of Embodiment 9, such as Fig.13 As shown, in this embodiment, it includes: a lower layout area 15 and an upper layout area 18; the lower layout area 15 is provided with a loading section 16, a transfer section 17 and a first spraying section 12 which are connected in sequence, the loading section 16 is arranged upwardly inclined along the travel direction of the vehicle 1, the transfer section 17 is arranged horizontally, and the first spraying section 12 is arranged downwardly inclined along the travel direction of the vehicle 1; the upper layout area 18 is provided with a drying section 14; the first spraying section 12 is connected to the drying section 14 through the second spraying section 13.

[0071] During the specific implementation process, this embodiment arranges the transport line in a double-layer factory building, realizes loading, transportation and the first spraying on the lower layer, and then uses the inclined transport section from the lower layer to the upper layer to realize the second spraying. The inclination of the first spraying section 12 and the second spraying section 13 can be opposite numbers to increase the uniformity of spraying. A drying section 14 is set on the upper layer of the factory building, and a drying room can also be set on the upper layer. The plate 19 is transported to the drying room after preliminary drying in the drying section 14. After the plate 19 is sprayed in the second spraying section 13, the first telescopic section 802 of the hook 8 makes the lower bottom surface of the plate 19 horizontal, so that the paint is leveled to avoid subsequent drying.

[0072] At present, the board material 19 used for furniture generally needs to be sprayed with three layers to ensure the comprehensive coverage and performance of the coating. Therefore, the first moving belt 3 and the second moving belt 4 in this embodiment can be adopted as follows: Fig.14 The driving device shown in the figure has winding rollers connected to both ends of the first moving belt 3 and the second moving belt 4, and the movement and reversal of the moving belts are achieved by the rotation of the winding rollers. Fig.14, when the right winding roller rotates clockwise, the moving belt moves to the right. When the left winding roller rotates counterclockwise, the moving belt moves to the left.

[0073] When in use, the plate 19 is sprayed in batches. After one batch of plates 19 is sprayed and dried, the next batch of plates 19 is sprayed. As shown in Example 9, the first layer is first sprayed on the outer surface of the plate 19 and sent to the drying room. After drying, the first moving belt 3 and the second moving belt 4 move in the opposite direction. When the plate 19 passes through the second spraying section 13 and the first spraying section 12, the second layer of coating is sprayed. A drying room can also be set in the transfer section 17. The drying room is set close to the first spraying section 12. If the drying room cannot be set close to the first spraying section 12 due to the layout of the factory area, a drying section 14 can be added as in Example 9 to preliminarily dry the second layer of coating and then transport it to the lower drying room. When the second layer of coating is dried, the first moving belt 3 and the second moving belt 4 move in the opposite direction again, driving the plate 19 through the first spraying section 12, the second spraying section 13 and the drying section 14 to enter the upper drying room, thereby completing the spraying and drying process of the three layers of coating. Of course, the process of the aforementioned circulation process can be adjusted according to the needs of different coating quantities.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
