Description

Technical Field

[0001] This invention relates to the field of board processing technology, specifically to a particleboard drawer curved surface sealing processing device based on an environmentally friendly coating system. Background Technology

[0002] In the context of green manufacturing for customized furniture, particleboard is widely used in the production of drawer components due to its cost and resource efficiency. The handle grooves often feature ergonomic, irregularly shaped curved surfaces to enhance product value. Currently, the industry standard practice is to first CNC mill the grooves, then fill the edge burrs and pores with environmentally friendly putty such as water-based putty, and finally coat them with low-VOC water-based paint or UV coating.

[0003] However, the loose and uneven fiber structure of particleboard makes it prone to fiber tearing, micro-chipping, and irregular pores when milling irregular curved surfaces of handles. Existing putty filling processes heavily rely on manual scraping or flat-adaptive coating equipment, making it difficult to accurately match the curved contours of irregular grooves. This results in uneven putty thickness after filling, increasing the workload of subsequent sanding and correction. Furthermore, water-based putty has a high drying shrinkage rate, and uneven thickness further induces the risk of coating cracking, making it difficult to meet the stringent quality stability requirements of large-scale production. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, the present invention aims to provide a particleboard drawer curved surface sealing processing device based on an environmentally friendly coating system. The device includes a worktable, a fixed clamp, and a movable hanger. The fixed clamp holds the particleboard, and the movable hanger moves along the length of the particleboard held by the fixed clamp. A vertically adjustable lifting seat is located at the top of the movable hanger. A horizontal scraper perpendicular to the particleboard is located on one side of the lifting seat, and side scrapers are located on both sides of the horizontal scraper. The horizontal scraper and side scrapers form a "U"-shaped notch at the top of the particleboard. During the movement of the movable hanger, the lifting seat moves vertically to maintain a consistent gap between the horizontal scraper and the top of the particleboard. A putty extrusion unit is located on the lifting seat, with its output end located on one side of the horizontal scraper.

[0005] To precisely adjust the height of the horizontal scraper for different irregular grooves in particleboard, the following features are specifically designed: A detection rod parallel to the horizontal scraper is located on one side of the movable hanger. The detection rod adheres to the upper surface of the particleboard when the movable hanger moves. Slider blocks are located at both ends of the detection rod and are slidably installed in vertically extending limiting holes on both sides of the movable hanger. A first distance sensor located above the slider is installed on the movable hanger to detect the height position of the slider. A linear actuator for driving the lifting seat to rise and fall is installed on the movable hanger, and a second distance sensor located above the particleboard is installed on the lifting seat.

[0006] To ensure real-time and uniform extrusion of putty, the following features are specifically designed: the putty extrusion unit includes a putty bucket fixedly installed on a lifting seat, a feeding pipe at the bottom of the putty bucket, the feeding pipe including a conveying pipe and an extrusion pipe, a rotating shaft rotatably installed inside the conveying pipe, and spiral conveying blades conforming to the inner wall of the conveying pipe are arranged around the rotating shaft. The putty extrusion unit also includes a rotary driver that drives the rotating shaft to rotate around its own axis.

[0007] To ensure that the extruded putty is scraped by the horizontal scraper and the side scraper, the following features are specifically designed: the extrusion tube is attached to one side of the horizontal scraper and located at the center of the horizontal scraper.

[0008] To ensure the stability of the lifting seat when adjusting its position in the vertical direction, the following features are specifically designed: the lifting seat is provided with several vertical guide columns, which are inserted into the movable hanger to guide the lifting seat.

[0009] In order to adjust the position of the side scraper on both sides of the horizontal scraper according to the putty thickness, the following features are specifically designed: several guide sleeves are provided on both sides of the horizontal scraper, the axis of the guide sleeves is horizontally set, and several guide rods are provided on the side scraper, the guide rods are inserted into the guide sleeves.

[0010] The side scraper is provided with a first threaded hole perpendicular to the surface of the horizontal scraper, and a first locking bolt is screwed into the first threaded hole.

[0011] To fix the particleboard in a stable vertical position, the following features are specifically provided: the fixing fixture includes a fixing block fixedly installed on the workbench and a moving block parallel to the fixing block. The workbench is provided with a limiting groove perpendicular to the length direction of the fixing block, and the moving block is slidably installed in the limiting groove.

[0012] The movable block is provided with a second threaded hole perpendicular to the surface of the workbench, and a second locking bolt is screwed into the second threaded hole.

[0013] In order to drive the movable hanger to move smoothly horizontally along the length of the particleboard, the following features are specifically provided: the workbench is provided with a linear slide for driving the movable hanger to move, and a linear slide rail for slidingly mounting the movable hanger.

[0014] The advantages of this invention compared to the prior art are as follows: This invention continuously and quantitatively extrudes putty onto the particleboard surface through a putty extrusion unit. Combined with horizontal and side scrapers, it effectively constrains the putty flow range, guides the putty to accurately fill the pores and micro-chipping of the rough cut surface, and the dynamic lifting adjustment of the lifting seat precisely controls the thickness of the filling layer. This achieves complete sealing of the irregular grooves of the particleboard while solving the problem of uneven putty thickness caused by irregular curved surfaces, effectively avoiding insufficient filling of recessed areas or excessive accumulation of protrusions.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Reference Figures 1 to 8 : A particleboard drawer curved surface sealing processing device based on an environmentally friendly coating system includes a workbench 1, a fixed clamp 1a, and a movable hanger 1b. The fixed clamp 1a is used to hold the particleboard, and the movable hanger 1b moves along the length of the particleboard held by the fixed clamp 1a. A vertically lifting seat 2 is provided at the top of the movable hanger 1b. A horizontal scraper 2a perpendicular to the particleboard is provided on one side of the lifting seat 2, and side scrapers 2a1 are provided on both sides of the horizontal scraper 2a. The horizontal scraper 2a and the side scrapers 2a1 form a "U"-shaped notch at the top of the particleboard. During the movement of the movable hanger 1b, the lifting seat 2 moves vertically to maintain the gap between the horizontal scraper 2a and the top of the particleboard. A putty extrusion unit 2b is provided on the lifting seat 2, and the output end of the putty extrusion unit 2b is located on one side of the horizontal scraper 2a.

[0027] In this application, the particleboard drawer panel to be processed is first securely clamped onto the workbench 1 using a fixing clamp 1a, with the side having the irregular groove facing upwards. Then, the positions of the horizontal scraper 2a and the side scraper 2a1 are adjusted so that the distance between the horizontal scraper 2a and the side scraper 2a1 and the top and sides of the particleboard are the same. Next, the moving hanger 1b moves at a constant speed along the length of the particleboard. During this movement, the putty extrusion unit 2b continuously extrudes a measured amount of putty onto the particleboard surface. Simultaneously, the lifting seat 2 adjusts its vertical position in real time according to the curved contour of the particleboard, dynamically maintaining a constant set gap between the horizontal scraper 2a and the top reference surface of the particleboard. The horizontal scraper 2a evenly applies the extruded putty, while the side scrapers 2a1 on both sides simultaneously trim the curved sidewalls of the groove. As the moving hanger 1b completes its entire trajectory, a putty sealing layer of uniform thickness and height is formed on the curved surface of the groove, providing a smooth base for subsequent environmentally friendly coating processes. In this embodiment, the putty extrusion unit 2b continuously and quantitatively extrudes putty onto the particleboard surface. Combined with the "U"-shaped notch structure formed by the horizontal scraper 2a and the side scraper 2a1, the putty flow range is effectively constrained, guiding the putty to precisely fill the pores and micro-chipped edges of the rough cut surface, thus completely sealing the irregular grooves of the particleboard. The dynamic lifting adjustment of the lifting seat 2 precisely controls the thickness of the filling layer, solving the problem of uneven putty thickness caused by irregular curved surfaces, and effectively avoiding insufficient filling in recessed areas or excessive accumulation in raised areas.

[0028] To precisely adjust the height of the horizontal scraper 2a for different irregular grooves in particleboard, the following features are specifically designed: A detection rod 1b1 parallel to the horizontal scraper 2a is provided on one side of the movable hanger 1b located on the horizontal scraper 2a. The detection rod 1b1 is in contact with the upper surface of the particleboard when the movable hanger 1b moves. Slider 1b2 is provided at both ends of the detection rod 1b1. The slider 1b2 is slidably installed in the vertically extending limiting holes 1b3 provided on both sides of the movable hanger 1b. A first distance sensor 1b4 is provided on the movable hanger 1b for detecting the height position of the slider 1b2 located above the slider 1b2. A linear actuator 1b5 for driving the lifting seat 2 to rise and fall is installed on the movable hanger 1b. A second distance sensor 2c located above the particleboard is provided on the lifting seat 2.

[0029] like Figures 2 to 6As shown, in this embodiment, the first distance sensor 1b4, the linear actuator 1b5, and the second distance sensor 2c are all connected via controller signals. When the moving hanger 1b moves along the length of the particleboard, the detection rod 1b1 located on one side of the horizontal scraper 2a moving direction always fits tightly against the upper surface of the particleboard. When it moves to the curved surface area of ​​the handle groove, it drives the sliders 1b2 at both ends to move vertically and vertically within the limiting hole 1b3 in undulation with the surface. The movement of the detection rod 1b1 takes precedence over the horizontal scraper 2a reaching this position. Therefore, the first distance sensor 1b4 can collect the height displacement data of the slider 1b2 in real time and accurately map the three-dimensional contour changes of the particleboard surface. Based on the contour signal, the controller drives the linear actuator 1b5 to dynamically adjust the vertical position of the lifting seat 2, maintaining a preset constant gap between the horizontal scraper 2a and the upper surface of the particleboard. Simultaneously, the second distance sensor 2c on the lifting seat 2 continuously monitors the actual gap value, forming a closed-loop feedback correction to ensure that the horizontal scraper 2a and the side scraper 2a1 can stably perform putty application and finishing actions even in complex curved surface areas. In this embodiment, the linear actuator 1b5 can be a cylinder or an electric push rod. This embodiment relies on the detection rod 1b1, in conjunction with the first distance sensor 1b4, to detect the curvature of the particleboard surface in real time before the horizontal scraper 2a arrives, thereby adjusting the height of the horizontal scraper 2a in real time. This ensures that the horizontal scraper 2a maintains the same gap as the surface when moving in the irregular groove curved surface area, thus ensuring a uniform and dense putty layer and reducing material waste and rework rate.

[0030] To ensure uniform and timely extrusion of the putty, the following features were specifically designed: The putty extrusion unit 2b includes a putty bucket 2b1 fixedly installed on the lifting base 2. The bottom of the putty bucket 2b1 is provided with a feeding pipe 2b2. The feeding pipe 2b2 includes a conveying pipe 2b3 and an extrusion pipe 2b4. A rotating shaft 2b5 is rotatably installed inside the conveying pipe 2b3. Spiral conveying blades 2b6 that fit against the inner wall of the conveying pipe 2b3 are provided around the rotating shaft 2b5. The putty extrusion unit 2b also includes a rotary driver 2b7 that drives the rotating shaft 2b5 to rotate around its own axis.

[0031] like Figure 4 As shown, in this embodiment, the putty is stored in a putty bucket 2b1 fixedly installed on the lifting seat 2. When the moving hanger 1b drives the lifting seat 2 to move along the length of the particleboard, the rotary driver 2b7 drives the rotating shaft 2b5 to rotate continuously, so that the spiral conveying blades 2b6 rotate tightly against the inner wall of the conveying pipe 2b3, stably pushing the putty in the putty bucket 2b1 through the conveying pipe 2b3 section of the feeding pipe 2b2 to the extrusion pipe 2b4, and continuously and quantitatively extruding it from the outlet of the extrusion pipe 2b4 onto the surface of the particleboard. The rotary driver 2b7 can be a servo motor. The precise control of the rotation speed of the rotating shaft 2b5 by the rotary driver 2b7 allows the putty extrusion amount to be flexibly adapted according to factors such as the width of the particleboard and the depth of the groove, avoiding local material shortages or overflows.

[0032] like Figure 6 As shown, in order to ensure that the extruded putty is scraped by the horizontal scraper 2a and the side scraper 2a1, the following features are specifically designed: The extrusion tube 2b4 is attached to one side of the horizontal scraper 2a and is located at the center of the horizontal scraper 2a.

[0033] like Figure 3 As shown, in order to ensure the stability of the path when the lifting seat 2 is adjusted in the vertical direction, the following features are specifically set: The lifting seat 2 is provided with several vertical guide columns 2d, which are inserted into the movable hanger 1b to guide the lifting seat 2.

[0034] In order to adjust the position of the side scraper 2a1 on both sides of the horizontal scraper 2a according to the putty thickness, the following features are specifically designed: Several guide sleeves 2a2 are provided on both sides of the horizontal scraper 2a. The axis of the guide sleeves 2a2 is set horizontally. Several guide rods 2a3 are provided on the side scraper 2a1. The guide rods 2a3 are inserted into the guide sleeves 2a2.

[0035] The side scraper 2a1 is provided with a first threaded hole 2a4 perpendicular to the surface of the horizontal scraper 2a, and a first locking bolt 2a5 is screwed into the first threaded hole 2a4.

[0036] like Figure 7 and Figure 8 As shown, in this embodiment, before processing, the operator loosens the first locking bolt 2a5, and manually pushes and pulls the side scraper 2a1 along the horizontal axis of the guide sleeve 2a2 according to the required thickness of the particleboard and the target putty thickness. The operator precisely adjusts the gap between the side scraper 2a1 and the side wall of the particleboard. After adjusting to the preset position, the operator tightens the first locking bolt 2a5 so that its end tightly presses against the surface of the horizontal scraper 2a, thereby achieving rigid locking of the side scraper 2a1.

[0037] To ensure the particleboard is fixed in a vertical and stable position, the following features are specifically designed: The fixed fixture 1a includes a fixed block 1a1 fixedly installed on the workbench 1 and a movable block 1a2 parallel to the fixed block 1a1. The workbench 1 is provided with a limiting groove 1a3 perpendicular to the length direction of the fixed block 1a1, and the movable block 1a2 is slidably installed in the limiting groove 1a3.

[0038] The movable block 1a2 is provided with a second threaded hole 1a4 perpendicular to the surface of the worktable 1, and a second locking bolt 1a5 is screwed into the second threaded hole 1a4.

[0039] like Figures 5 to 8As shown, in this embodiment, during clamping, the particleboard is placed vertically on the workbench 1, with one side tightly against the fixed block 1a1. The operator slides the moving block 1a2 along the limiting groove 1a3 to the other side of the particleboard until it is tightly fitted to the board surface, completing the initial positioning and clamping. Then, the second locking bolt 1a5 on the moving block 1a2 is tightened, allowing it to pass through the second threaded hole 1a4 and firmly press its end against the surface of the workbench 1, rigidly locking the moving block 1a2 within the limiting groove 1a3. The particleboard maintains a stable vertical posture throughout the entire processing, providing a stable reference support for the smooth movement of the moving hanger 1b along its length and for the precise scraping of the horizontal scraper 2a and the side scraper 2a1, effectively avoiding putty filling deviations caused by workpiece offset.

[0040] like Figure 7 and Figure 8 As shown, in order to drive the movable hanger 1b to move smoothly horizontally along the length of the particleboard, the following features are specifically designed: The workbench 1 is provided with a linear slide 1c for driving the movement of the movable hanger 1b, and a linear slide rail 1c1 for slidingly mounting the movable hanger 1b.

[0041] Working Principle: In operation, the particleboard drawer to be processed is first securely clamped onto the workbench 1 using the fixing clamp 1a, with the side with the irregular groove facing upwards. Then, the positions of the horizontal scraper 2a and the side scraper 2a1 are adjusted so that the distance between the horizontal scraper 2a and the side scraper 2a1 and the top and sides of the particleboard are the same. Next, the moving hanger 1b moves at a constant speed along the length of the particleboard. During this movement, the putty extrusion unit 2b continuously extrudes a measured amount of putty onto the particleboard surface. Simultaneously, the lifting seat 2 adjusts its vertical position in real time according to the curved contour of the particleboard, dynamically maintaining a constant set gap between the horizontal scraper 2a and the top reference surface of the particleboard. The horizontal scraper 2a and the side scraper 2a1 uniformly apply the extruded putty. As the moving hanger 1b completes its entire trajectory, a putty sealing layer of uniform thickness and height is formed on the grooved surface, providing a smooth base for subsequent environmentally friendly coating processes.

[0042] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
