Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of foam board processing equipment, specifically to a foam board surface treatment device. Background Technology

[0002] In the field of foam board processing, it is common to increase the bonding strength by rubbing the surface of foam board with sandpaper. However, due to structural design defects, traditional processing equipment is difficult to adapt to the different processing needs of flat and curved surfaces of foam board, resulting in poor surface treatment effect and low production efficiency.

[0003] The structural drawbacks of existing equipment are mainly manifested in the following aspects: First, the sandpaper processing component adopts a fixed flat installation structure, lacking a flexible support design that can be adjusted to conform to the shape. When processing curved foam boards, the fixed flat sandpaper cannot conform to the curvature of the surface, resulting in uneven contact pressure between the sandpaper and the board surface. For example, when processing arc-shaped foam boards, the sandpaper can only contact the top area of ​​the arc, and the sides of the arc surface are not sufficiently rubbed due to insufficient contact, resulting in reduced adhesive strength. Second, the equipment's adjustment mechanism is rudimentary, relying mostly on manual screws or slots for positioning. It is necessary to stop the machine and manually adjust the tilt angle and height of the sandpaper processing component. When dealing with foam boards of different curvatures, the adjustment process is time-consuming, laborious, and lacks precision. If two different curvatures of foam boards are changed, the operator needs to repeatedly calibrate the angle of the sandpaper component, and angular deviations can easily lead to uneven sandpaper wear.

[0004] With the expanding applications of foam boards in building decoration, cold chain packaging, and other fields, their surface structures are showing a diversified trend, including flat surfaces, single-curvature curved surfaces, and multi-curvature composite surfaces. For example, foam boards for irregularly shaped packaging often include transitional structures between curved and flat surfaces. Traditional equipment, due to structural defects such as "lack of conformal processing, low adjustment efficiency, and insufficient self-adaptive capability," can no longer meet the process requirement of "uniform friction of foam boards with different surface structures." There is an urgent need to develop new equipment with flexible conformal processing and intelligent dynamic adjustment functions to solve the industry problem of poor surface treatment adaptability. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a foam board surface treatment device, which solves the technical problem that the existing sandpaper treatment components adopt a fixed planar installation structure and lack a flexible support design that can be adjusted according to the shape. When treating curved foam boards, the sandpaper on the fixed plane cannot fit the curvature of the curved surface, resulting in uneven contact pressure between the sandpaper and the board surface.

[0006] According to one aspect, at least one embodiment of this disclosure provides a foam board surface treatment apparatus, comprising:

[0007] A processing table and a top frame, wherein the top frame is fixed on the processing table;

[0008] A guiding conveyor assembly is disposed between the processing table and the top frame;

[0009] A surface treatment assembly includes a main hydraulic cylinder fixed to the top of a top frame. A main frame is provided at the output end of the main hydraulic cylinder. A main wheel is provided inside the main frame and rotated by a motor. A pair of tension rollers are rotatably connected inside the main frame. A pair of swing rods are rotatably connected to both sides of the main frame via a rotating shaft. An adjusting roller is rotatably connected between the pair of swing rods. Sanding belts are fitted on the main wheel, the tension rollers, and the adjusting rollers.

[0010] As a further technical solution, driven gears are provided at both ends of the rotating shaft of the swing arm, a horizontal shaft is rotatably connected inside the main frame, a drive gear is provided at both ends of the horizontal shaft, and an adjustment motor is provided inside the main frame.

[0011] As a further technical solution, transmission gears are provided on both the output end of the regulating motor and the horizontal shaft, and idler gears are provided on both sides of the main frame, with the idler gears meshing between the driving gear and the driven gear on one side.

[0012] As a further technical solution, the guiding and conveying assembly includes a pair of conveying rollers, both of which are installed at both ends of the processing table. The conveying rollers are located on both sides of the top frame, and a through cavity is opened in both ends of the top frame.

[0013] As a further technical solution, a vertical hydraulic cylinder is installed in the cavity, and a crossbeam is connected to the output end of the vertical hydraulic cylinder. A pair of lower pressure rollers are rotatably connected between the crossbeams, and an outer frame is provided on both sides of the top frame.

[0014] As a further technical solution, an adjusting screw is installed inside the bottom of the outer frame, and a moving block is slidably connected to both ends of the bottom of the outer frame. The moving block is connected to the adjusting screw through a threaded connection, and a correction roller is rotatably connected to the bottom of the moving block.

[0015] As a further technical solution, a dust collection component is also included. The dust collection component is disposed inside the processing table. The dust collection component includes a dust collection chamber, which is opened inside the processing table. Both ends of the dust collection chamber are open at the top. A connecting pipe is provided at the bottom of the processing table, and the connecting pipe is connected to the inside of the dust collection chamber.

[0016] As a further technical solution, both ends of the tension roller surface are provided with raised structures, and the thickness of the sand belt is lower than the raised portion of the tension roller.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] 1. In this disclosure, the surface treatment component adjusts the height of the main frame through the main hydraulic cylinder to adapt to foam boards of different thicknesses, adjusts the motor drive gear system to make the swing rod drive the adjusting roller to move up and down, change the curvature of the sanding belt, fit the flat or curved surface of the foam board, the main wheel drives the sanding belt to grind, and the raised structure on the surface of the tension roller prevents the sanding belt from detaching. This solves the problem that traditional equipment cannot adapt to different surface structures, ensures uniform contact between the sanding belt and the foam board, and improves the surface treatment quality and bonding strength.

[0019] 2. In this disclosure, the conveying roller of the guide conveying assembly provides forward power, the vertical hydraulic cylinder drives the lower pressure roller to clamp the foam board with the conveying roller to prevent vertical jumping, the adjusting screw drives the moving block to move the correcting roller laterally to correct the conveying deviation of the foam board, forming a positioning structure to ensure that the foam board moves along the center line of the processing table, providing accurate positioning for surface treatment, improving processing consistency and efficiency, and reducing uneven processing caused by deviation.

[0020] 3. In this disclosure, the dust collection chamber opening of the dust collection component corresponds to the sanding belt grinding area. The slag generated by the sanding of the foam board falls directly into the dust collection chamber. The connecting pipe at the bottom of the processing table is connected to the negative pressure system to suck up dust and slag in time, avoid slag accumulation affecting the conveying and processing quality, keep the processing environment clean, reduce the impact of dust on equipment and operators, and improve the stability and safety of equipment operation.

[0027] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0033] like Figures 1-4 As shown, it illustrates a foam board surface treatment apparatus according to an embodiment of the present disclosure, comprising:

[0034] A processing table 1 and a top frame 2, wherein the top frame 2 is fixed on the processing table 1;

[0035] A guide conveyor assembly 4 is disposed between the processing table 1 and the top frame 2;

[0036] Surface treatment assembly 3 includes a main hydraulic cylinder 3-1, which is fixed to the top of the top frame 2. A main frame 3-2 is mounted on the output end of the main hydraulic cylinder 3-1. A main wheel 3-3 is housed within the main frame 3-2 and rotates under motor control. A pair of tension rollers 3-4 are rotatably connected within the main frame 3-2. A pair of swing rods 3-5 are rotatably connected to both sides of the main frame 3-2 via rotating shafts. An adjusting roller 3-6 is rotatably connected between the pair of swing rods 3-5. The main wheel 3-3, tension rollers 3-4, and the... A sanding belt 3-13 is fitted onto the adjusting roller 3-6. Both ends of the rotating shaft of the swing rod 3-5 are provided with driven gears 3-7. A horizontal shaft 3-8 is rotatably connected inside the main frame 3-2. Both ends of the horizontal shaft 3-8 are provided with driving gears 3-9. An adjusting motor 3-10 is installed inside the main frame 3-2. Both the output end of the adjusting motor 3-10 and the horizontal shaft 3-8 are provided with transmission gears 3-11. Idler wheels 3-12 are provided on both sides of the main frame 3-2. The idler wheel 3-12 meshes between the driving gear 3-9 and the driven gear 3-7 on one side.

[0037] In some examples, a dynamically adjustable structure is designed to allow the surface treatment component 3 to be adjusted according to the curvature of the foam board surface. The main hydraulic cylinder 3-1 is fixed to the top of the top frame 2, and the main frame 3-2 at its output end can move up and down to adapt to the thickness of the foam board. The main wheel 3-3 inside the main frame 3-2 is driven to rotate by a motor, which drives the tension roller 3-4 and the adjusting roller 3-6 through the sanding belt 3-13 to form a transmission circuit. The swing rods 3-5 on both sides of the main frame 3-2 are rotatably connected to the main frame 3-2 through a rotating shaft. The adjusting roller 3-6 is installed between the swing rods 3-5. When there is curvature on the surface of the foam board, the adjusting motor 3-10 drives the horizontal shaft 3-8 to rotate through the transmission gear 3-11. The driving gears 3-9 at both ends mesh with the driven gear 3-7 through the idler gear 3-12, causing the swing rods 3-5 to swing around the rotating shaft. The adjusting roller 3-6 moves up and down accordingly, changing the curvature of the sanding belt 3-13. This structure, through the linkage of the gear transmission system and the swing rod 3-5, allows the sanding belt 3-13 to conform to the curvature of the foam board surface, ensuring uniform contact between the sanding belt 3-13 and the board surface, avoiding uneven processing caused by the curvature of the board, and achieving precise sanding of foam board surfaces with different curvatures.

[0038] like Figures 1-4 As shown in the figure, the guide conveying assembly 4 in this embodiment includes a pair of conveying rollers 4-1. The pair of conveying rollers 4-1 are installed at both ends of the processing table 1. The conveying rollers 4-1 are located on both sides of the top frame 2. A through cavity 4-2 is opened in both ends of the top frame 2. A vertical hydraulic cylinder 4-3 is installed in the through cavity 4-2. The output end of the vertical hydraulic cylinder 4-3 is connected to a cross frame 4-4. A pair of downward pressure rollers 4-5 are rotatably connected between the cross frames 4-4. An outer frame 4-6 is provided on both sides of the top frame 2. An adjusting screw 4-7 is installed in the bottom of the outer frame 4-6. A moving block 4-8 ​​is slidably connected to both ends of the bottom of the outer frame 4-6. The moving block 4-8 ​​is connected to the adjusting screw 4-7 by a threaded engagement. A correcting roller 4-9 is rotatably connected to the bottom of the moving block 4-8.

[0039] In some examples, a guide conveyor assembly 4 is designed to centrally convey the foam board. Conveyor rollers 4-1 at both ends of the processing table 1 provide forward propulsion. Vertical hydraulic cylinders 4-3 within the cavities 4-2 at both ends of the top frame 2 drive the crossbeam 4-4 to move up and down, creating a clamping structure between the lower pressure roller 4-5 and the conveyor rollers 4-1 to prevent the board from jumping up and down. When the adjusting screws 4-7 within the outer frames 4-6 on both sides of the top frame 2 rotate, they drive the moving blocks 4-8 to slide along the bottom of the outer frames 4-6, causing the correcting rollers 4-9 at the bottom of the moving blocks 4-8 to move laterally. When the foam board deviates during conveying, the correcting rollers 4-9 on both sides can move synchronously towards the center, pushing the board to the center position of the processing table 1 through lateral thrust. The vertical pressure of the lower pressure roller 4-5 and the lateral constraint of the correcting roller 4-9 work together to form a three-dimensional positioning structure: the lower pressure roller 4-5 ensures that the board fits against the conveying roller 4-1, and the correcting roller 4-9 corrects the offset in real time, so that the board always moves along the center line of the processing table 1, providing a precisely positioned processing object for the surface treatment component 3 and ensuring the consistency of the surface treatment process.

[0040] like Figures 1-4 As shown, this embodiment also includes a dust collection component 5, which is disposed inside the processing table 1. The dust collection component 5 includes a dust collection chamber 5-1, which is opened inside the processing table 1. Both ends of the dust collection chamber 5-1 are open structures. A connecting pipe 5-2 is provided at the bottom of the processing table 1, and the connecting pipe 5-2 is connected to the inside of the dust collection chamber 5-1.

[0041] In some examples, a dust collection assembly 5 is designed to absorb the debris from surface treatment. The dust collection chamber 5-1 within the processing table 1 has openings at both ends at the top, corresponding to the sanding area of ​​the sanding belt 3-13. When the sanding belt 3-13 produces debris while sanding the foam board, the debris falls directly into the dust collection chamber 5-1. A connecting pipe 5-2 at the bottom of the processing table 1 connects to the dust collection chamber 5-1 and can be connected to a negative pressure dust collection system. Airflow draws the debris from the dust collection chamber 5-1 into an external collection device. The opening of the dust collection chamber 5-1 is aligned with the sanding area to ensure that debris falls directly into the dust collection chamber 5-1, reducing debris accumulation on the surface of the processing table 1. The connection pipe 5-2, in conjunction with the negative pressure system, forms an active dust collection structure that promptly removes the debris generated during sanding, preventing debris residue from affecting subsequent board conveying or surface treatment quality, while maintaining a clean processing environment.

[0042] For example, such as Figure 4 As shown, both ends of the tension roller 3-4 have raised structures, and the thickness of the sand belt 3-13 is lower than the raised portion of the tension roller 3-4.

[0043] In some examples, the raised structure at the edge can block the sand belt 3-13 inside, avoiding the drawback of separation of the tension roller 3-4.

[0044] In actual use: The top frame 2 is fixed on the processing table 1. The conveying rollers 4-1 of the guide conveying assembly 4 are installed at both ends inside the processing table 1. The vertical hydraulic cylinder 4-3 in the cavity 4-2 of the top frame 2 connects the horizontal frame 4-4 and the lower pressure roller 4-5. The adjusting screw 4-7 in the outer frame 4-6 drives the moving block 4-8 ​​and the correcting roller 4-9. The main hydraulic cylinder 3-1 of the surface treatment assembly 3 is fixed on the top of the top frame 2. The main frame 3-2 is connected through the output end of the hydraulic cylinder. The main wheel 3-3 inside the main frame 3-2 is driven by a motor. The tensioning roller 3-4 is rotatably connected inside the main frame 3-2. The swing rod 3-5 is connected to the main frame 3-2 through a rotating shaft. The adjusting roller 3-6 is installed between the swing rods 3-5. The sanding belt 3-13 is fitted onto the main wheel. On tension roller 3-3 and adjusting roller 3-6, adjusting motor 3-10 drives swing arm 3-5 through gear system. Dust collection chamber 5-1 of dust collection assembly 5 is opened in processing table 1. Connecting pipe 5-2 is located at the bottom of processing table 1. During use, conveying roller 4-1 drives foam board to move. Vertical hydraulic cylinder 4-3 adjusts the height of lower pressure roller 4-5. Adjusting screw 4-7 drives correcting roller 4-9 to correct offset. Main hydraulic cylinder 3-1 adjusts the height of main frame 3-2. Adjusting motor 3-10 drives swing arm 3-5 to change the position of adjusting roller 3-6 so that sanding belt 3-13 fits the curvature of foam board surface. Main wheel 3-3 drives sanding belt 3-13 to polish. Dust collection assembly 5 sucks in dust through connecting pipe 5-2.
