Description

Technical Field

[0001] This utility model relates to the field of wood processing equipment technology, and in particular to a wood processing spray painting device. Background Technology

[0002] As a widely used material, wood is subject to surface painting as a crucial process during its processing. Painting not only gives wood a beautiful appearance but also effectively improves its wear resistance, corrosion resistance, and water resistance, thus extending its service life. Currently, in the wood processing industry, especially for small and medium-sized enterprises or specific workpieces, partially automated or semi-automated painting equipment usually requires changing the corresponding clamps or performing tedious equipment debugging when processing wood of different lengths and cross-sectional dimensions. This greatly increases the production preparation time, and manual intervention is still required to flip and adjust the wood during painting.

[0003] Some existing technologies lack structures that can adaptively clamp wood of different sizes, which may result in low applicability of the clamping structure in actual use, thus affecting production efficiency. Furthermore, for some long pieces of wood with different diameters, most equipment often cannot achieve continuous spraying in one go, all-round. Multiple positioning or manual intervention may be required to complete the coverage of the entire surface. This is not only complicated to operate, but also prone to color differences or uneven thickness at the joints, making it impossible to guarantee the continuity and consistency of large-area painting. Utility Model Content

[0004] The main objective of this invention is to provide a wood processing painting device that effectively solves the problem mentioned above. The existing technologies lack a structure that can adaptively clamp wood of different sizes, which may result in low applicability of the clamping structure in actual use, thus affecting production efficiency. Furthermore, for some long pieces of wood with different diameters, most equipment often struggles to achieve continuous, all-around spraying in one go, requiring multiple positioning steps or manual intervention to cover the entire surface. This is not only complex to operate but also prone to color differences or uneven thickness at joints, failing to guarantee the continuity and consistency of large-area painting.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A wood processing painting device includes a painting table, a clamping mechanism installed on the front side of the outer surface of the painting table, wood on the inner surface of the clamping mechanism, a painting mechanism on the upper end of the wood, and an auxiliary painting mechanism installed on the outer surface of the painting mechanism.

[0006] Preferably, a mounting base is installed on the right side of the top of the spray booth, an electric door panel is installed at the front end of the inner surface of the mounting base, a collection component is provided at the lower end of the electric door panel, the collection component is installed on the front side of the inner surface of the spray booth, and a spray box is provided on the outer surface of the spray booth.

[0007] Preferably, the clamping mechanism includes an outer frame, which is installed on the front side of the bottom of the spray booth. Support frames are installed on the left and right sides of the bottom of the outer frame. A drive box is installed on the left end of the outer frame. Movable seats are symmetrically slidably connected to the inner surface of the outer frame. The inner surfaces of the two movable seats are threaded together with a bidirectional threaded rod. The left end of the bidirectional threaded rod is installed at the output end of the drive box.

[0008] Preferably, a control box is installed on the top of each of the two movable seats, an electric telescopic rod is installed on the top of the control box, a bearing support is installed on the top of the electric telescopic rod, a rotating shaft is provided on the inner surface of each of the two bearing supports, a clamping plate is installed at the opposite end of each of the two rotating shafts, and a pressure sensor is installed on the opposite side of the inner surface of each of the two clamping plates.

[0009] Preferably, a second drive box is installed at the left end of the bearing support located at the left end, and the second drive box is rotatably connected to the rotating shaft at the left end.

[0010] Preferably, the painting mechanism includes a painting end head, a corrugated pipe is provided in the middle of the upper end of the painting end head, and a material conveying channel is installed at both the upper and lower ends of the corrugated pipe. The bottom of the material conveying channel at the lower end is installed in the middle of the top of the painting end head, and a material conveying pump is installed at the top of the material conveying channel at the upper end. A material storage tank is installed on the top of the material conveying pump.

[0011] Preferably, the auxiliary painting mechanism includes a support platform, with the outer surface of the material conveying channel at the upper end penetrating the middle of the upper inner surface of the support platform, and the bottom of the material pump and the storage tank are both installed on the top of the support platform.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This device, through its designed clamping mechanism, allows the distance between the two clamping plates to be adjusted by rotating a bidirectional threaded rod. Under the action of the electric telescopic rod, the clamped wood can be lifted upwards, making the device suitable for wood of different lengths and sizes without the need to change clamps or perform complex adjustments. The electric telescopic rod works in conjunction with the rotating shaft; as the shaft rotates, the wood rotates around its circumference. During this rotation, the painting mechanism continuously and stably sprays paint onto the entire outer surface of the wood, ensuring consistent paint film thickness at all angles and on curved surfaces. This fundamentally solves the unevenness problem caused by manual turning, significantly improving the painting quality and efficiency of the product.

[0014] 2. This device features an auxiliary spraying mechanism that works in conjunction with the main spraying mechanism. The auxiliary spraying mechanism supports the main spraying mechanism and allows for adjustment of the left and right positions of the spraying head, enabling the wood to be sprayed from end to end. This significantly improves the flexibility and comprehensiveness of the spraying process, making it particularly suitable for processing large areas of wood. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Example 1, as Figure 1 As shown, a wood processing painting device includes a painting station 1, a clamping mechanism 2 is installed on the front side of the outer surface of the painting station 1, wood 3 is provided on the inner surface of the clamping mechanism 2, a painting mechanism 4 is provided on the upper end of the wood 3, and an auxiliary painting mechanism 5 is installed on the outer surface of the painting mechanism 4.

[0019] In this embodiment, the door panel of the paint spray box 9 is opened, and the wood 3 is loaded onto the opposite side of the two clamping plates 210 through the top of the mounting base 7. At this time, the wood 3 is located on the top of the electric door panel 6. Through the adaptive clamping and lifting function of the clamping mechanism 2, the wood 3 is firmly clamped and adjusted to a suitable painting height. Start the auxiliary painting mechanism 5, and adjust the initial horizontal position of the painting end 401 in the painting mechanism 4 according to the length of the wood 3 so that it is aligned with one end of the wood 3. At the same time, the material conveying system of the painting mechanism 4 is ready. The rotation function of the clamping mechanism 2 is activated, causing the wood 3 to rotate uniformly around its axis. At the same time, the painting mechanism 4 starts painting, and the painting end 401 continuously sprays paint onto the surface of the rotating wood 3. While the wood 3 is rotating, the auxiliary spraying mechanism 5 drives the spraying head 401 to move horizontally along the length of the wood 3, thereby spraying the entire outer surface of the wood 3. After the painting is completed, wait for the wood 3 to dry completely before resetting all mechanisms. Then, loosen and remove the processed wood 3. Take the wood 3 out of the paint spray box 9 by reversing the loading steps. Excess paint generated during the painting process is recycled through the collection component 8.

[0020] For details, please refer to Figure 1 , Figure 2 and Figure 6 In this embodiment, a mounting base 7 is installed on the right side of the top of the spray booth 1, an electric door panel 6 is installed at the front end of the inner surface of the mounting base 7, a collection component 8 is provided at the lower end of the electric door panel 6, the collection component 8 is installed on the front side of the inner surface of the spray booth 1, and a spray box 9 is provided on the outer surface of the spray booth 1. During the painting process, excess paint that does not adhere to the surface of the wood 3 will fall under the action of gravity. This paint is received by the collection component 8 on the front side of the spray painting station 1. The collection component 8 guides the paint to the collection box through its internal waste collection channel, realizing the recycling or centralized treatment of the paint. Further reference Figure 2 , Figure 3 and Figure 4 In this embodiment, the clamping mechanism 2 includes an outer frame 201, which is installed on the front side of the bottom of the spray booth 1. Support brackets 202 are installed on the left and right sides of the bottom of the outer frame 201. A drive box 203 is installed on the left end of the outer frame 201. Moving seats 204 are symmetrically slidably connected to the inner surface of the outer frame 201. The inner surfaces of the two moving seats 204 are threaded together with a bidirectional threaded rod 205. The left end of the bidirectional threaded rod 205 is installed at the output end of the drive box 203. Further reference Figure 3 and Figure 4 In this embodiment, a control box 206 is installed on the top of each of the two movable seats 204. An electric telescopic rod 207 is installed on the top of the control box 206. A bearing support 208 is installed on the top of the electric telescopic rod 207. A rotating shaft 209 is provided on the inner surface of each of the two bearing supports 208. A clamping plate 210 is installed on the opposite end of each of the two rotating shafts 209. A pressure sensor 211 is installed on the opposite side of the inner surface of each of the two clamping plates 210. A drive box 212 is installed on the left end of the bearing support 208 located on the left end. The drive box 212 is rotatably connected to the rotating shaft 209 on the left end. Place the wood 3 between the two clamps 210, start the drive box 203, and the drive motor inside it drives the bidirectional threaded rod 205 to rotate. Since the threads at both ends of the bidirectional threaded rod 205 are opposite, the two movable seats 204 connected to it will move towards or away from each other along the guide rail inside the outer frame 201. This design utilizes the mechanical principle of a bidirectional lead screw to efficiently and synchronously convert the rotational motion of the motor into the linear opening and closing motion of the two clamping plates 210. When the clamping plates 210 contact the wood 3, the pressure sensor 211 installed on the inner side of the clamping plates 210 will monitor the clamping pressure in real time. When the pressure value reaches the preset threshold, the pressure sensor 211 sends a signal to the controller of the drive box 203, and the controller immediately stops the drive motor, thereby realizing automated and constant pressure clamping of wood of different diameters, avoiding the problem of excessive clamping force damaging the wood or insufficient clamping force causing unstable clamping. When clamping wood 3 of different diameters, after extending the electric telescopic rod 207 until the clamping plate 210 is at the center of the wood 3, rotate the double-threaded rod 205 to clamp the wood 3 through the clamping plate 210, thus achieving the effect of being suitable for wood 3 of different diameters. After clamping is completed, the electric telescopic rod 207 can be activated through the control box 206 according to the painting requirements. The electric telescopic rod 207 extends and pushes the bearing support 208 at its top and the entire clamping assembly to move vertically upward. This design utilizes the precise linear displacement characteristics of the electric telescopic rod 207. By controlling the extension and retraction of the electric telescopic rod 207, the clamped wood 3 can be raised to the required painting height. This allows the device to adapt to painting processes at different heights, greatly improving the versatility and flexibility of the equipment, without the need to replace the clamps or perform complex mechanical adjustments. During the painting process, the drive box 212 is started, and the drive motor inside drives the left end of the rotating shaft 209 to rotate. Since the two clamping plates 210 have firmly clamped the wood 3, the rotation of the rotating shaft 209 will drive the wood 3 and the right end of the rotating shaft 209 to rotate 360° in the bearing support 208. By actively driving the wood 3 to rotate, and with the fixed paint spraying end 401, continuous and uniform spraying of the circumferential surface of the wood is achieved. This fundamentally solves the technical problem of low efficiency in traditional manual flipping and spraying. Through the designed clamping mechanism 2, the distance between the two clamping plates 210 can be adjusted by rotating the bidirectional threaded rod 205. Under the action of the electric telescopic rod 207, the clamped wood 3 can be lifted upward, making this device applicable to wood 3 of different lengths and sizes without the need to change clamps or perform complex adjustments. The electric telescopic rod 207 and the rotating shaft 209 work together. Under the rotation of the rotating shaft 209, the wood 3 can be rotated around the circumference of the rotating shaft 209. During the rotation, the painting mechanism 4 can continuously and stably spray the entire outer surface of the wood 3, significantly improving the painting quality and efficiency of the product.

[0021] Example 2: Based on Example 1, this example adds a painting mechanism 4 for painting the wood 3 and an auxiliary painting mechanism 5 for adjusting the left and right displacement of the nozzle at the painting mechanism 4. By setting the auxiliary painting mechanism 5, the painting mechanism 4 can be supported, and the left and right position of the painting end 401 can be adjusted, so that the wood 3 can be painted from end to end.

[0022] For details, please refer to Figure 2 and Figure 5 In this embodiment, the painting mechanism 4 includes a painting end 401. A corrugated pipe 402 is provided in the middle of the upper end of the painting end 401. Material conveying channels 403 are installed at both the upper and lower ends of the corrugated pipe 402. The bottom of the material conveying channel 403 at the lower end is installed in the middle of the top of the painting end 401. A material conveying pump 404 is installed at the top of the material conveying channel 403 at the upper end. A storage tank 405 is installed at the top of the material conveying pump 404. The storage tank 405 stores paint. After the delivery pump 404 is started, the paint is drawn out from the storage tank 405 and delivered to the spray nozzle 401 through the upper delivery channel 403 and the corrugated pipe 402, and then atomized and sprayed out by the spray nozzle 401. The corrugated pipe 402 serves as a flexible connection here. When the auxiliary painting mechanism 5 drives the painting end 401 to move left and right, the corrugated pipe 402 can extend, retract and bend accordingly, ensuring the sealing and continuity of the paint conveying channel during the dynamic movement of the painting end 401, and preventing leakage or interruption. Further reference Figure 2 and Figure 5 In this embodiment, the auxiliary painting mechanism 5 includes a support platform 501. The outer surface of the material conveying channel 403 located at the upper end penetrates the middle of the upper inner surface of the support platform 501. The bottom of the material pump 404 and the storage box 405 are both installed on the top of the support platform 501. A movable seat 502 is slidably connected to the middle of the inner surface of the support platform 501. A threaded rod 503 is threadedly connected to the inner surface of the movable seat 502. A drive box 504 is installed on the left side of the support platform 501 near the threaded rod 503. The left end of the threaded rod 503 is installed at the output end of the drive box 504. While the wood 3 is driven to rotate by the clamping mechanism 2, the drive box 3 504 of the auxiliary painting mechanism 5 is activated. The drive box 3 504 drives the threaded rod 2 503 to rotate, which in turn drives the movable seat 2 502 connected to it to slide horizontally in the support platform 501, i.e., the axial direction of the wood 3. Support brackets are provided on both sides of the bottom of the storage box 405. Since the material conveying channel 403, the material pump 404 and the storage box 405 of the painting mechanism 4 are all installed on the support platform 501, the movement of the movable seat 2 502 drives the painting end 401 to move horizontally in sync. The rotation of wood 3 ensures that its circumference is evenly covered, while the axial movement of the paint spraying end 401 ensures that the paint can cover the wood from one end to the other. This composite motion trajectory of "rotation + translation" forms a spiral spraying path, which ensures that the paint can cover the entire outer surface of wood 3, and can improve the flexibility and comprehensiveness of the spraying to a certain extent. The auxiliary spraying mechanism 5 is designed to work in conjunction with the spraying mechanism 4. The auxiliary spraying mechanism 5 can support the spraying mechanism 4 and adjust the left and right positions of the spraying end 401, thereby spraying the wood 3 and significantly improving the flexibility and comprehensiveness of the spraying.

[0023] In this solution, spiral steel strip type screw protective sleeves are installed on the outside of both the bidirectional threaded rod 205 and the threaded rod 503 to prevent paint from entering the thread groove and to ensure normal mechanical processing and production. The drive box 1 203, drive box 2 212 and drive box 3 504 in this solution include the mounting box, drive motor and controller as in the prior art. The drive motor and controller are installed inside the mounting box. The controller here can be a motor controller that is compatible with the drive motor in the prior art, and can play the role of controlling the drive motor's switching and rotation speed. The control box 206 in this solution includes the existing mounting enclosure and electric telescopic pole controller. The controller here can be the Dongyuxiang YMD602, model: YMD602, voltage range: supports 12V / 24V / 36V / 48V, output power: 38W, load capacity 2000N, built-in limit switch, supports stroke control, supports communication with PLC, and is suitable for industrial equipment that requires precise control of the telescopic pole stroke. The pressure sensor 211 in this solution can be a pressure sensor from the TEConnectivity series, which is used to measure and monitor pressure. The pressure sensor 211 monitors the pressure change between itself and the contact object in real time and converts the pressure signal into an electrical signal and sends it to the drive box 203. The controller inside the drive box 203 presets a pressure threshold. When the received pressure signal reaches or exceeds the threshold, the controller will trigger the corresponding control logic to stop the rotation of the bidirectional threaded rod 205, thereby maintaining the current clamping pressure state. The collection component 8 in this solution includes a waste collection channel and collection box as in the prior art, used to recycle excess paint from three locations on the wood. The mounting base 7 in this solution is equipped with an electric telescopic rod, which drives the electric door panel 6 to move forward and backward by extending and retracting the electric telescopic rod. The paint spraying box 9 in this solution can be a wood painting processing box in the existing technology, which includes a box door that can be opened and closed for loading and unloading materials. Since the above are all very mature products in the prior art, they will not be described in detail in this application.

[0024] It should be noted that the specific installation methods, circuit connection methods, and control methods of the drive box 1 203, drive box 2 212, and drive box 3 504 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0025] In Example 3, based on Examples 1 and 2 above, a hot air drying device can be installed inside the support 501 near the wood 3 to dry the wood 3 with low airflow during the painting process.

[0026] Because the hot drying equipment continuously blows air onto the wood 3 at a low speed during use, the interference caused by the air blowing on the painting path is small under the basic condition of low air speed, and it will not affect the normal painting process. In addition, since the hot drying equipment blows air continuously during use, it can prevent paint from splashing into the inside of the air blowing equipment. After the painting is completed, the drying time of the wood 3 can be accelerated by the drying equipment in the prior art placed in front of the wood 3. After the wood 3 is completely dry, the various mechanisms are reset, and then the wood 3 is taken out from the paint spray box 9 for unloading.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
