Description

Technical Field

[0001] The present invention relates to the field of particleboard production equipment, and in particular to a production device and process for paint-free door panel highly resistant to deformation particleboard. Background Art

[0002] In the existing production of highly resistant particleboard for paint-free door panels, traditional processing techniques face significant technical bottlenecks. The cutting and trimming processes of the particleboard are separated, requiring the use of a panel saw and a trimmer, respectively. This not only occupies a large area (approximately 80 square meters for a single production line), but also requires time and effort to transport the panels between the two processes, resulting in low overall production efficiency. The processing cycle for a single door panel can be as long as 15-20 minutes. Furthermore, the lack of an effective pressure structure during the cutting process leads to frequent edge chipping caused by panel vibration, which not only increases the cost of subsequent polishing but also reduces the panel's resistance to deformation due to the damaged edge structure. Edge cracking is also prone to occur in environments with large humidity fluctuations. Furthermore, traditional equipment has poor versatility, requiring frequent tool and fixture changes for different panel thicknesses, with machine adjustment times as long as 30-60 minutes, making it difficult to adapt to the customized production needs of multiple specifications and small batches. Therefore, we propose a production equipment and process for highly resistant particleboard for paint-free door panels to address these issues. Summary of the Invention

[0020] S1.2, Vacuum adsorption fixation: The vacuum pump is started, and negative pressure is generated through the adsorption holes on the top plate to firmly fix the plate on the workbench to prevent displacement during cutting;

The air outlet and the glue outlet are alternately distributed on the guide rod to achieve continuous and uniform edge protection treatment during the rotation process.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. During the actual cutting process, the present invention lowers the cutter to one side of the plate through the lead screw 3, and drives the cutter to extend and retract to adjust the height of the chassis through the cylinder, so that the side of the top plate close to the chassis fits the upper and lower end surfaces of the plate. Then, the hollow motor is started to drive the top plate, the cutter and the chassis to rotate at high speed through the fixed seat. The carbide cutting edges of the cutter and the top plate and the chassis, which are evenly distributed on the outer periphery, form a continuous cutting surface during rotation, thereby achieving the precise processing of the arc edges of the upper and lower edges of the plate while achieving the cutting of the plate. This can break through the two processes of cutting first and then trimming in the traditional processing steps, and complete the processing in one step, thereby greatly improving the processing efficiency.

[0037] 2. The gap between the top plate and the bottom plate of the present invention is precisely controlled by the stroke of the cylinder, and can adapt to any thickness of plate within the adjustment range, which can meet most plate specifications on the market, and is beneficial to the actual processing work. During the cutting process, the annular flanges of the top plate and the bottom plate can protect the upper and lower surfaces of the plate, forming a simultaneous "cutting-protection" process: on the one hand, the vibration of the plate is reduced through physical constraints, and on the other hand, the generation of edge collapse is suppressed at the moment of chip formation, which is beneficial to the actual cutting work.

[0038] 3. In the actual processing process of the present invention, the edge of the cut plate can be protected by the edge protection component. When the hollow motor drives the gear ring 1 to rotate, it will drive the gear ring 2 engaged with it to rotate synchronously. The gear ring 2 can drive the driving gear to rotate, and the driving gear can drive the meshing driven gear to rotate synchronously, so that the guide rod and the guide tube can rotate synchronously. The air pump outputs compressed air through the notch on the outer periphery of the guide tube to remove debris generated by cutting and ensure the subsequent gluing effect.

[0039] 4. The present invention extracts protective glue from the glue storage chamber through the output pump, and guides it to the glue outlet through the glue guide hole in the guide rod. Thereafter, the brush is used to evenly apply it to the edge of the cut of the plate after cutting in a rotary coating manner. During the gluing process, the air pump will deliver compressed air to the air outlet through the ventilation hole to accelerate the drying of the protective glue. The air outlet and the glue outlet on the guide rod are alternately distributed, and continuous and uniform edge protection treatment is achieved during the rotation process. The alternating distribution design of the air outlet and the glue outlet realizes the synchronous cycle of "air cleaning-glue coating-air curing", thereby achieving full protection of the cut after cutting, avoiding loosening and slag falling due to vibration at the cut of the subsequent plate during transportation, and is beneficial to maintaining the quality of the finished product and subsequent protection of the plate.

[0053] Furthermore, in specific implementation, the paint-free door panel high deformation resistance particleboard production equipment realizes efficient processing through the collaborative work of multiple components. Before processing, people can first place the board on the top plate 104 on the top of the frame 102, and position the board horizontally and vertically. After completing the initial positioning, start the vacuum pump to generate negative pressure through the adsorption holes 109 of the top plate 104, and firmly fix the board on the workbench to prevent the board from shifting during the cutting process. Vacuum adsorption replaces traditional mechanical clamps to avoid damage to the board surface while providing uniform pressure, especially to prevent thin boards from deformation due to uneven clamping force. During the processing, a three-dimensional adjustment system is formed by the lead screw 103, lead screw 2 106 and lead screw 3 108 on both sides, which respectively drive the movable frame 105, the slide 107 and the mounting frame 110 to realize X / Y / Z axis precise positioning for cutting processing.

The carbide cutting edges uniformly distributed on the outer periphery of the cutter 119, the top plate 121 and the chassis 117 form a continuous cutting surface during rotation, so that the arc edges of the upper and lower sides of the plate can be accurately processed while cutting the plate, thereby breaking through the traditional processing. The two processes of cutting and then trimming in the steps are completed in one process, which can greatly improve the processing efficiency. The gap between the top plate 121 and the bottom plate 117 is precisely controlled by the stroke of the cylinder 112, and can adapt to any thickness of the plate within the adjustment range. It can meet most of the plate specifications on the market, which is beneficial to the actual processing work. During the cutting process, the annular flanges of the top plate 121 and the bottom plate 117 can protect the upper and lower surfaces of the plate, forming a simultaneous "cutting-protection": on the one hand, the vibration of the plate is reduced by physical constraints, and on the other hand, the edge collapse is suppressed at the moment of chip formation, which is beneficial to the actual cutting work. During the actual processing, the edge protection component can protect the cut edge of the plate.

[0076] Working principle:

[0077] In actual use, the paint-free door panel high deformation resistance particleboard production equipment realizes efficient processing through the coordinated work of multiple components. Before processing, people can first place the board on the top plate 104 on the top of the frame 102 and position the board horizontally and vertically. After completing the initial positioning, start the vacuum pump to generate negative pressure through the adsorption holes 109 of the top plate 104, and firmly fix the board on the workbench to prevent the board from shifting during the cutting process. Vacuum adsorption replaces the traditional mechanical clamp to avoid damage to the board surface while providing uniform pressure, especially to prevent thin boards from deformation due to uneven clamping force. During the processing, a three-dimensional adjustment system is formed by the lead screw 1 103, the lead screw 2 106 and the lead screw 3 108 on both sides, which respectively drive the moving frame 1 05. The slide 107 and the mounting frame 110 realize precise positioning of the X / Y / Z axes for cutting processing. When actually cutting, the cutter 119 is lowered to one side of the plate by the lead screw 108, and the cutter 119 is driven by the cylinder 112 to adjust the height of the chassis 117 so that the side close to the top plate 121 and the chassis 117 fits the upper and lower end surfaces of the plate. Then, the hollow motor 116 is started to drive the top plate 121, the cutter 119 and the chassis 117 to rotate at high speed through the fixed seat 120. The carbide cutting edges evenly distributed on the outer periphery of the cutter 119, the top plate 121 and the chassis 117 form a continuous cutting surface during rotation, so that the curved edges of the upper and lower edges of the plate can be cut at the same time as the plate is cut. Precise processing can break through the two processes of cutting and then trimming in the traditional processing steps, and complete the processing in one time, which can greatly improve the processing efficiency. The gap between the top plate 121 and the bottom plate 117 is accurately controlled by the stroke of the cylinder 112, which can adapt to any thickness of the plate within the adjustment range and can meet most of the plate specifications on the market, which is beneficial to the actual processing work. During the cutting process, the annular flanges of the top plate 121 and the bottom plate 117 can protect the upper and lower surfaces of the plate, forming a simultaneous "cutting-protection": on the one hand, the vibration of the plate is reduced by physical constraints, and on the other hand, the edge collapse is suppressed at the moment of chip formation, which is beneficial to the actual cutting work. In the actual processing process, the edge protection component can be used to The hollow motor 116 drives the gear ring 134 to rotate, and the gear ring 2 124 meshing with it is driven to rotate synchronously. The gear ring 124 can drive the driving gear 122 to rotate, and the driving gear 122 can drive the meshing driven gear 123 to rotate synchronously, so that the guide rod 131 and the conduit 126 can rotate synchronously. The air pump outputs compressed air through the notch 118 on the outer periphery of the conduit 126 to remove the debris generated by the cutting and ensure the subsequent gluing effect. At the same time, the output pump extracts the protective glue from the glue storage cavity, and guides it through the glue guide channel in the guide rod 131 to the glue outlet 132. Then, the brush 125 evenly applies it to the cut edge of the cut plate by rotary coating. During the gluing process,The air pump delivers compressed air to the air outlet 130 through the ventilation channel to accelerate the drying of the protective glue. The air outlet 130 and the glue outlet 132 on the guide rod 131 are alternately distributed, achieving continuous and uniform edge protection during rotation. The alternating distribution of the air outlet 130 and the glue outlet 132 realizes a synchronous cycle of "air cleaning-glue coating-air curing", fully protecting the cut after slicing, preventing the cut of the subsequent plate from loosening and falling debris due to vibration during transportation, and is conducive to maintaining the quality of the finished plate and subsequent protection.
