Description

Technical Field

[0001] This utility model relates to the technical field of MDF cutting equipment, specifically to an automatic MDF stacking and feeding device and an MDF cutting system. Background Technology

[0002] Medium-density fiberboard (MDF) is a type of fiberboard made from wood fibers or other plant fibers. The fibers are processed, coated with synthetic resin, and pressed under heat and pressure. Based on their density, it can be classified into high-density fiberboard, medium-density fiberboard, and low-density fiberboard. The nominal density of medium-density fiberboard is typically around 0.65 g / cm³. 3 -0.80g / cm 3 Medium-density fiberboard (MDF) is widely used in furniture, decoration, musical instruments, and packaging in China due to its uniform structure, fine texture, stable performance, impact resistance, and ease of processing.

[0003] MDF (Medium-density Fiberboard) is typically cut into standard-sized boards using a CNC saw. Currently, loading the CNC saw mainly relies on manual operation, which has the following drawbacks: Low efficiency: Manually stacking the raw MDF sheets is time-consuming and labor-intensive, especially in batch processing scenarios, where frequent manual operations can severely slow down the production pace; Equipment damage: During manual stacking, the contact between the MDF and the CNC saw is often an uneven collision, which can easily impact the worktable and transmission components of the CNC saw, shortening the equipment's lifespan over time; Insufficient precision: Manual stacking relies on operator experience, and it is difficult to guarantee the neatness of the boards, which may affect the accuracy of subsequent cutting and processing; High labor intensity: MDF is relatively heavy, and operators are prone to fatigue during manual handling and stacking, increasing occupational safety risks.

[0004] To address the above issues, there is an urgent need to invent an automatic MDF stacking and feeding device and an MDF cutting system to solve problems such as low feeding efficiency, high labor intensity, and low standardization in the current MDF cutting and feeding process. Utility Model Content

[0005] The first aspect of this utility model is to provide an automatic stacking and feeding device for MDF boards, the primary objective of which is to improve feeding efficiency, enhance the positioning accuracy of MDF board feeding, and reduce labor intensity.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution.

The device includes an MDF pushing device and an MDF stacking and discharging device. The MDF pushing device includes a carrying platform and an XZ drive device.

The movement of the XZ drive device along the X-axis direction causes the MDF on the carrying platform to be subjected to frictional force in the X-axis direction. Under the action of frictional force, the MDF on the carrying platform is conveyed to the MDF stacking and discharging device.

[0013] According to the above-described automatic MDF stacking and feeding device, the MDF stacking and discharging device further includes a mounting frame, and the suspended air platform is installed within the mounting frame. The first, second, third, and fourth aligning plate assemblies can move relative to the suspended air platform in the Z direction, allowing the MDF to freely enter and exit the MDF aligning and discharging device.

The device includes an MDF pushing device 2 and an MDF stacking and discharging device 3. The MDF pushing device 2 includes a loading platform 21 and an XZ drive device 22. The loading platform 21 is configured to carry the MDF. The relative movement of the loading platform 21 and the XZ drive device 22 in the Z-axis direction causes the MDF on the loading platform 21 to be subjected to pressure in the Z-axis direction. The XZ drive device 22 is configured to move in the X-axis direction. The movement of the XZ drive device 22 in the X-axis direction causes the MDF on the loading platform 21 to be subjected to frictional force in the X-axis direction. Under the action of frictional force, the MDF on the loading platform 21 is conveyed to the MDF stacking and discharging device 3. The MDF stacking and unloading device 3 includes a Y-axis stacking system 31, an X-axis feeding system 32, and a suspended air platform 33 (Guangdong Fulai Quan'en Intelligent Equipment Co., Ltd., dimensions 2400*1165*1000+50mm, power 2.2kw). The Y-axis stacking system 31 is configured to stack the MDF along the Y-axis, and the X-axis feeding system 32 is configured to convey the MDF along the X-axis to the working position of the computer saw 1 and position the MDF in the X and Y directions.

[0037] The specific working process of the MDF cutting system: MDF pushing device: The rubber pad at the bottom of the Z-axis drive device falls down during operation, and the rubber pad contacts the surface of the MDF and generates pressure; the X-axis drive system drives the whole to move along the X direction, and uses the friction between the rubber pad and the MDF to move the MDF smoothly to the MDF stacking and discharge device. MDF stacking and unloading device: The Y-axis stacking system drives the stacking board with a cylinder to push the MDF board into a neat position in the Y-axis direction; the X-axis feeding system achieves the same stacking in the X-axis direction; after stacking is completed, the X-axis feeding system controls the cylinder to move through the PLC subroutine to push the neat MDF board to the operator or computer saw work position.

[0038] The main innovation of this invention lies in the fact that it replaces manual operation with an automated process of "pushing-aligning-discharging" to achieve impact-free conveying of MDF boards. The rubber pad design reduces hard contact between the board and the equipment, and the cylinder drive of the X / Y axis alignment mechanism ensures alignment accuracy. The overall structure achieves stability and efficiency in the feeding process.

[0039] Through the above design, this invention realizes the automatic feeding function of computer saw, improves feeding efficiency, avoids the impact of manual stacking on the computer saw, reduces the labor intensity of operators, and ensures the accuracy and stability of subsequent processing.
