Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, and more specifically to a grooving processing equipment for furniture sheets that can quickly switch milling wheels. Background Technology

[0002] In the furniture manufacturing and decorative panel processing industry, to meet the needs of design aesthetics, structural connection, or functional integration, it is often necessary to mill various types and specifications of grooves on the surface or edges of the panels. The core working component of the furniture panel grooving machine used to complete this process is usually a high-speed rotating milling wheel (or grooving cutter) that forms a precisely dimensional and smooth groove on the panel.

[0003] Utility model patent application number 202121079727.5 discloses a grooving device for panel furniture boards. This device includes a frame, a grooving platform for placing the boards to be processed, a drive device for moving the grooving platform along the grooving direction, a push device for moving the boards perpendicular to the grooving direction, a grooving device for performing the grooving process, and a pressure plate device for holding the boards to achieve board positioning. This panel furniture board grooving device achieves automated grooving, improves grooving accuracy and reduces error rates, and increases production efficiency and process consistency. However, when dealing with diverse production needs, such equipment requires processing grooves of various specifications and shapes on the surface of furniture boards. In this case, the process of changing and adjusting the milling wheels is extremely cumbersome and cannot achieve rapid switching. For example, when it is necessary to change the groove type (such as switching from a V-groove to a U-groove) or adjust the groove width, the operator must first stop the machine, manually remove the old groove wheel using special tools, and then reinstall the new groove wheel of the corresponding model or specification. This makes the entire groove wheel replacement process complicated, and each replacement often takes ten minutes or even longer, which seriously restricts the equipment utilization rate and the production cycle of small-batch, multi-variety orders. Based on this, this application proposes a furniture board grooving processing equipment that can effectively solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a furniture board grooving processing equipment that can quickly switch milling groove wheels, so as to solve the technical problems of existing panel furniture board grooving equipment that requires downtime to change milling groove wheels when dealing with diverse production needs, resulting in cumbersome operation and long downtime.

[0005] This invention is achieved through the following technical solution: A furniture board grooving processing equipment includes a chassis, a controller, a board conveying mechanism disposed at the front end of the chassis, and a milling processing mechanism disposed inside the chassis. The milling processing mechanism includes a stepped cylinder fixedly disposed inside the chassis, a carrier ring rotatably mounted on the stepped cylinder, and a plurality of transmission units evenly distributed along the circumference of the carrier ring. The transmission unit includes a transmission shaft that slides axially through the carrier ring, a milled grooved wheel fixed to the front end of the transmission shaft, a guide assembly disposed on the transmission shaft, and a bevel driven gear fixed to the rear end of the transmission shaft. The outer circular surface of the stepped cylinder is provided with a guide closed-loop groove that cooperates with all the guide components. The guide closed-loop groove has a drive section that allows the drive shaft to slide axially and extends out of the front side of the machine box and is located above the processing station of the plate conveying mechanism. The chassis is equipped with an adjustment mechanism that is connected to the carrier ring and is actively controlled by the controller. The adjustment mechanism drives the carrier ring to rotate, thereby rotating any of the transmission units to the processing station.

[0006] As a further provision of the above scheme, the adjustment mechanism includes a toothed ring fixedly connected coaxially to the carrier ring, a movable rack meshing with the toothed ring, and a drive assembly for driving the movable rack to move linearly.

[0007] As a further provision of the above solution, the drive assembly includes a servo motor, a transmission screw driven by the servo motor, and a screw nut block that is threadedly engaged with the transmission screw and fixedly connected to the moving rack.

[0008] As a further provision of the above scheme, a power unit is provided inside the chassis, and a bevel drive gear is provided at the output end of the power unit, and the bevel drive gear meshes with the bevel driven gear at the rear end of the transmission unit located at the processing station.

[0009] As a further provision of the above scheme, the guide assembly includes a bearing housing that is rotatably fixed to the drive shaft, and a guide wheel that interacts with the guide closed-loop groove is provided on the bearing housing.

[0010] As a further feature of the above scheme, the guide closed-loop groove is formed by a smooth connection between an arc segment located at the lower rear of the stepped cylinder and a V-shaped segment located at the upper front of the stepped cylinder.

[0011] As a further feature of the above scheme, the outer edge of the carrier ring is provided with a plurality of mounting holes evenly distributed in the circumference, and a linear bearing is provided in each mounting hole, with the transmission shaft passing through the linear bearing.

[0012] As a further feature of the above scheme, a dust cover is also provided on the outside of the processing station, and a gap is left between the lower end of the dust cover and the plate conveying mechanism for the plate to pass through, and a negative pressure dust removal component is connected to the upper end of the dust cover.

[0013] As a further feature of the above solution, a row of conveyor rollers driven by a conveyor motor is provided at both the left and right ends of the dust cover.

[0014] As a further feature of the above solution, the dust cover is provided with a telescopic drive component, and the telescopic end of the telescopic drive component is rotatably connected to a top pressure head that mates with the center positioning hole at the front end of the milling groove wheel located at the machining station.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The furniture board grooving processing equipment disclosed in this invention uses a rotatable carrier ring to integrate and install multiple milling groove wheels of different specifications, and drives the carrier ring to rotate in increments through an adjustment mechanism precisely controlled by a controller. When it is necessary to change the groove type, only a command needs to be input on the controller, and the target groove wheel can be automatically rotated and positioned to the processing station in a short time. This completely eliminates a series of cumbersome steps such as machine stoppage and manual disassembly and assembly in the traditional method, greatly shortens the tool change time, significantly improves equipment utilization and production flexibility, and is particularly suitable for small-batch, multi-variety production modes.

[0016] The milling mechanism in this invention achieves precise guidance and positioning of the axial sliding of the transmission unit through the mechanical cooperation between the guide wheel and the guide closed-loop groove, ensuring the repeatability of the milling wheel extension position after each switch. Simultaneously, the automatic meshing design of the bevel driven gear and bevel driving gear after sliding into position ensures the accuracy and reliability of power transmission. This mechanical positioning and meshing mechanism fundamentally avoids human operation errors and guarantees the consistency of processing quality across different batches of products. Furthermore, by integrating multiple tool positions into a single rotating ring, the overall structure is compact and space-saving.

[0017] The present invention also provides axial auxiliary support for the high-speed rotating milling groove wheel before processing by adding a top pressure component, which effectively suppresses the radial vibration of the tool, significantly improves dynamic balance and processing stability, thereby enabling the processing of a smoother and more precise groove to meet the product quality requirements.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-7 This application will be described in detail with reference to the embodiments. Example 1

[0022] like Figure 1 and Figure 2 As shown in Embodiment 1, a furniture board grooving processing device is disclosed, the main body of which includes a chassis 10 and a controller 20. A board conveying mechanism 30 is provided on the front side of the chassis 10, and a processing port 101 for extending milling groove wheels is opened on the front side of the chassis 10 above the conveying mechanism 30. A key milling processing mechanism 40 is provided inside the chassis 10. This milling processing mechanism 40 can store various milling groove wheels and can automatically switch the selected groove wheel to the working position at the processing port 101.

[0023] The board conveying mechanism 30 includes a conveying seat 301 connected to the front side of the housing 10. The conveying seat 301 is stably supported by several support legs 302 on its lower surface. A row of rollers 303 is rotatably arranged in the conveying seat 301. The furniture board to be processed can be placed on the rollers 303 and moved smoothly in the left and right directions under the push of external force (manual or automatic).

[0024] Reference Appendix Figures 4 to 6 The core of the milling mechanism 40 is a stepped cylinder 401 fixedly installed inside the housing 10, with the machining port 101 directly facing the top area of ​​the stepped cylinder 401. A carrier ring 402 is rotatably fitted onto the front end of the stepped cylinder 401 via bearings. Multiple mounting holes (six are used in this embodiment 1) are evenly spaced around the outer edge of the carrier ring 402, and a linear bearing 403 is press-fitted into each mounting hole. A drive shaft 404 passes through each linear bearing 403, allowing it to slide axially and rotate stably within it. A milling groove wheel 405 of a specific type is connected to the front end of each drive shaft 404 via a flange or thread. These milling groove wheels 405 can cover different types such as straight groove wheels, V-grooves, and U-grooves to meet diverse grooving requirements.

[0025] Each drive shaft 404 has a bevel driven gear 406 fixedly connected to its rear end. A guide wheel 408 is rotatably connected to the middle section of the drive shaft 404 via a bearing housing 407. A continuous guide closed-loop groove 409 is precisely machined on the outer cylindrical surface of the middle section of the stepped cylinder 401. This guide closed-loop groove 409 is smoothly connected by an arc segment 4091 located at the lower rear and a V-shaped segment 4092 located at the upper front, with the tip of the V-shaped segment 4092 located at the top center of the stepped cylinder 401. All guide wheels 408 on the drive shafts 404 are embedded in this guide closed-loop groove 409. When the carrier ring 402 drives a drive shaft 404 to rotate to the top position, its guide wheel 408 will move along the inclined surface of the V-shaped segment 4092, forcing the drive shaft 404 to slide forward axially along the linear bearing 403, ultimately causing the milled groove wheel 405 at its front end to precisely extend out of the machining port 101 and be in the machining position.

[0026] To drive the milling wheel 405 in the machining station, a crossbeam frame 410 is fixed to the upper part of the inner cavity of the machine housing 10. A power unit 411 consisting of a power motor and a reducer is mounted on the crossbeam frame 410, and the output shaft of the power unit 411 is connected downward to a bevel drive gear 412. When the drive shaft 404 carries the milling wheel 405 to the top working position, the bevel driven gear 406 at its end can just enter a fully meshed state with the bevel drive gear 412, thereby receiving rotational power.

[0027] To achieve precise indexing rotation of the carrier ring 402, an adjustment mechanism 50 controlled by the controller 20 is also provided inside the chassis 10. This adjustment mechanism 50 includes a toothed ring 501 coaxially fixedly connected to the carrier ring 402, and a movable rack 502 meshing with the toothed ring 501. The movable rack 502 forms a helical pair with a transmission screw 503 driven by a servo motor 504 via a screw nut block 505 on it, and both the servo motor 504 and the transmission screw 503 are mounted on the crossbeam frame 410. A guide hole 5021 is also provided on the movable rack 502, through which the movable rack 502 engages with a guide slide rod 506 fixed inside the chassis 10, ensuring that it can only move smoothly along a straight line, and that the servo motor 504 is precisely controlled by the controller 20.

[0028] When the grooving equipment for furniture boards disclosed in Embodiment 1 needs to switch the milling groove wheel 405, the operator selects the target groove wheel model through the interface of the controller 20. Then the controller 20 will automatically generate the corresponding control signal according to the input information, thereby controlling the servo motor 504 to rotate precisely the corresponding number of revolutions or angles.

[0029] Driven by the servo motor 504, the transmission screw 503 starts to rotate, and through the cooperation between the screw nut block 505 and the screw nut block 505, the moving rack 502 moves precisely a set distance along the guide slide bar 506. During this process, the meshing transmission between the moving rack 502 and the toothed ring 501 will cause the carrier ring 402 to rotate around the central axis of the stepped cylinder 401 by a set angle. During the rotation of the carrier ring 402, all drive shafts 404 will rotate synchronously. When the drive shaft 404 of the corresponding milling groove wheel 405 rotates to the top of the stepped cylinder 401, the drive shaft 404 will move forward through the action between the guide wheel 408 and the V-shaped segment 4092 until it rotates to the top of the stepped cylinder 401. At this time, the milling groove wheel 405 extends out of the machining port 101 and is placed at the machining position. At the same time, the bevel driven gear 406 connected to its end also meshes with the bevel driving gear 412, so that the power unit 411 can transmit the machining power to the drive shaft 404 and the milling groove wheel 405.

[0030] After the milling groove wheel 405 is adjusted, the operator presses the start button on the controller 20. The milling groove wheel 405 rotates at high speed under the power input of the power unit 411. Then, the furniture board is pushed from left to right along a row of rollers 303 and passes through the milling groove wheel 405 to complete the surface grooving treatment of the board. Example 2

[0031] Example 2 discloses a furniture board grooving processing equipment optimized based on the technical solution in Example 1. The similarities between it and Example 1 will not be repeated.

[0032] like Figure 1 and Figure 3 As shown, a dust cover 60 is installed on the front side of the chassis 10, completely covering the processing opening 101, and a gap sufficient for the sheet metal to pass through is left between the lower end of the dust cover 60 and the idler roller 303. At the same time, a dust extraction pipe 61 is connected to the upper end of the dust cover 60, and the dust generated during processing is drawn to the filtration and dust removal equipment (not shown in the figure) by a negative pressure fan 62, which greatly improves the working environment.

[0033] Secondly, on the left and right side walls of the dust cover 60, multiple conveyor rollers 64 driven by independent conveyor motors (not shown) are installed via strips 63. When the front end of the sheet enters the dust cover 60, the conveyor rollers 64 can clamp the sheet and automatically drive it to pass through the processing area at a uniform speed, realizing automatic feeding and freeing up operators.

[0034] Finally, a telescopic drive component 65 (such as a servo electric cylinder or pneumatic cylinder) is installed on the front side of the dust cover 60 corresponding to the machining station. The telescopic end of the telescopic drive component 65 is equipped with a pressing head 67 via a rotating connecting sleeve 66. Before the milling groove wheel 405 begins high-speed rotation, the controller 20 can instruct the telescopic drive component 65 to move, pushing the pressing head 67 forward so that it accurately inserts into and presses against the center positioning hole at the front end of the milling groove wheel 405. This design provides an additional axial support point for the high-speed rotating milling groove wheel 405, thereby effectively suppressing vibration, significantly improving dynamic balance and machining stability, and thus obtaining a smoother and more precise groove machining quality.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
