Description

Technical Field

[0001] This utility model relates to the field of particleboard processing technology, specifically to an automatic particleboard edge trimming device. Background Technology

[0002] In furniture manufacturing and interior decoration, particleboard, as a commonly used engineered wood product, is widely used in the production of wardrobes, cabinets, and flooring substrates due to its advantages such as wide availability of raw materials, low production costs, and stable physical properties. However, after initial processing, particleboard often has rough edges, insufficient dimensional accuracy, and poor flatness. If these issues are not addressed, they will not only affect the accuracy of subsequent assembly processes but also reduce the final product's appearance quality and user experience.

[0003] However, existing traditional particleboard edge trimming operations mostly rely on manual operation or semi-automated equipment. Manual trimming primarily involves operators using handheld cutting tools (such as handheld chainsaws or edge trimmers) to cut and sand the particleboard edges. This method has significant drawbacks: firstly, the operator's skill level and proficiency directly determine the trimming quality, easily leading to cutting deviations and uneven edges, making it difficult to guarantee consistent product quality in mass production; secondly, manual operation is inefficient, labor-intensive, and generates a large amount of sawdust during the cutting process, exposing operators to a dusty environment for extended periods, seriously threatening their physical and mental health.

[0004] Therefore, those skilled in the art have provided an automatic edge trimming device for particleboard to solve the problems mentioned in the background art. Utility Model Content

A spur gear 403 is fixed on the inner side of one end of the adjusting plate 402, and the two sets of spur gears 403 of the adjusting plate 402 mesh with each other; A synchronous motor body 404 is connected to the top of the spur gear 403 in a single adjusting plate 402. The synchronous motor body 404 is fixedly installed on the inner wall of the fixed frame 401. A pressing frame 405 is slidably arranged on the outer side of the adjusting plate 402 away from the fixed frame 401. The inner wall of the pressing frame 405 is provided with a sliding groove. The adjusting plate 402 is located at one end inside the pressing frame 405. Both its upper and lower surfaces are rotatably equipped with ball bearings 406. An adjusting base 11 is rotatably installed on the inner side of the trimming table 1. A bottom shaft frame 12 is fixed to the bottom wall of the trimming table 1 at the bottom of the adjusting base 11. The adjusting base 11 is rotatably installed on the bottom shaft frame 12.

A trimming and cutting machine 17 is installed above the trimming groove 2. An electric hydraulic cylinder 18 is installed on the top of the trimming and cutting machine 17, and a screw block 19 is fixed at the top of the electric hydraulic cylinder 18. A screw hole is opened on the inner side of the screw block 19, and a lead screw 20 is installed in the screw hole for spiral transmission.

[0017] The working principle of the above embodiments is as follows: The particleboard to be processed is placed on the adjusting base 11 of the trimming table 1. After the device is started, the controller 10 sends a command to drive the synchronous motor 16 to run. The synchronous motor 16 drives the adjusting rod 13 and the adjusting base 11 fixed thereto to rotate precisely on the bottom shaft frame 12 through the transmission pair formed by the worm gear 14 and the worm wheel 15, thereby realizing the automatic adjustment of the particleboard processing angle to adapt to the processing requirements of different edges. To ensure the stability of the trimming process, the edge pressing mechanism needs to be precisely positioned and clamped in space: the electric hydraulic cylinder 5 drives the entire adjusting structure 3 to descend to the predetermined height, and then the servo motor 307 starts, driving the worm gear 306 and worm wheel 305 to mesh and drive the fixed rod 304 and the adjusting top plate 301 to rotate. The top plate 301 is adjusted to achieve stable support and rotation through the top ring frame 303 and the rotating shaft ring 302, and finally the pressing edge structure 4 installed on it is adjusted to the target position. The synchronous motor body 404 located on the fixed frame 401 is started, driving the meshing spur gears 403 to cause a pair of rotating plates 402 to rotate relative to each other. The balls 406 at the end of the rotating plates 402 roll in the groove of the pressing frame 405, converting the rotational motion into the linear extension and retraction motion of the pressing frame 405, thereby implementing adaptive clamping on the edge of the particleboard. The trimming operation is performed by the trimming and cutting machine 17, which has multi-degree-of-freedom motion capability: Lateral feed X-axis: Servo motor 21 rotates after receiving the command, driving lead screw 20. Lead screw 20 drives electric hydraulic cylinder 18 and trimming and cutting machine 17 to move laterally along frame 22 through screw block 19 connected by screw pair, thus precisely controlling the cutting path. Longitudinal positioning Y-axis: Electric hydraulic cylinder 24 drives the entire frame 22 to slide longitudinally along the limiting rod 23 on the top frame 6 to adapt to different sizes of particleboard or to perform multiple trimmings; Vertical feed Z-axis: Electric hydraulic cylinder 2 18 controls the vertical lifting and lowering of the trimming and cutting machine 17, realizing the cutting blade's entry and exit actions. Through the coordinated operation of the above three axes, high-precision and automated trimming of the particleboard edge is completed. The wood chips and dust generated during the trimming process fall into the sealed collection channel 8 through the trimming groove 2 under negative pressure, and are finally efficiently and centrally collected by the vacuum cleaner 9, ensuring a clean working environment and safe production.
