Description

Technical Field

[0001] This utility model belongs to the field of wood processing technology, specifically relating to a fan-shaped board tail arc machine. Background Technology

[0002] Currently, the side panels of wooden rolls, drums, and other winding carriers are all made by assembling several triangular logs after beveling and rounding them with hoops. In the traditional process of converting triangular logs into fan-shaped boards, the structure of the triangular boards is different from that of conventional rectangular boards, and the tail needs to be processed into an arc shape. Existing conventional board conversion machines are not suitable for processing such irregularly shaped boards. Some existing arc conversion machines that can convert boards mostly require manual assembly and fixation of the boards to form a whole board, and then placing the whole board on the arc conversion machine for arc processing. The entire processing process is time-consuming and inefficient in the early preparation stage, and the board cutting yield is low, resulting in serious wood waste. Furthermore, this processing method requires uniformity in the size of the wood, which is not suitable for use by board manufacturers at the source of the wood.

[0003] Therefore, we propose a circular arc processing machine for the tail section of a fan-shaped plate that can continuously process single plates. Utility Model Content

[0004] The purpose of this invention is to provide a fan-shaped plate tail arc machine to solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fan-shaped plate tail arc machine includes a worktable, on the top surface of which a circular tray is rotatably mounted, and inside the worktable is a drive mechanism for driving the tray to rotate.

[0007] Furthermore, the side of the workbench is constructed from bottom to top by a frame to form a chip removal chamber, a working chamber, and a pressure adjustment chamber that are connected vertically. The chip removal chamber, the working chamber, and the pressure adjustment chamber are respectively equipped with a chip removal trough for discharging wood chips, a chamfering mechanism for cutting the tail of the triangular plate, and a pressure mechanism for pressing and limiting the wood board. The side of the working chamber closest to the workbench has an open design.

[0008] Furthermore, a material unloading mechanism is also installed on the side of the top of the workbench to unload the processed triangular plate.

[0009] Furthermore, the top of the tray is provided with several concentric rings of the same height from the inside out, and the side of the ring used to support the plate has a toothed design.

[0010] Furthermore, the top of the workbench is equipped with several annular guide rails concentrically arranged with the tray, and the bottom of the tray is equipped with several rollers around the circumference corresponding to the positions of each guide rail, in order to support the tray to rotate smoothly on the workbench.

[0011] Furthermore, the drive mechanism mainly consists of a geared motor and a planetary gear reducer. The output end of the geared motor is connected to the power input end of the planetary gear reducer, and the output end of the planetary gear reducer is connected to the center position of the tray.

[0012] Furthermore, the chamfering mechanism includes a bracket mounted on the side wall frame of the work compartment. The bracket has a notch in the middle, and a base for mounting a chamfering motor is hinged to the middle of the bracket near the front end. A cutting disc is mounted on the output end of the chamfering motor mounted on the base. A T-shaped adjusting rod is rotatably mounted on the rear of the base. The lower end of the adjusting rod is located inside the notch and is fixed inside the notch by two threaded adjusting nuts. The upper edge of the cutting disc is close to the edge of the tray.

[0013] Furthermore, the pressing mechanism includes two support rods mounted on the side wall frame of the pressing adjustment chamber. A carrier plate is horizontally mounted on the two support rods. The carrier plate is located on the side of the support rods near the worktable, and several sleeves are vertically arranged in the middle of the carrier plate. A top rod is slidably inserted into the inner side of each sleeve. A connecting column is integrally formed at the top end of the top rod, and a connector is integrally formed at the bottom end of the top rod. A spring is fitted on the outer side of the top rod between the connector and the sleeve.

[0014] Furthermore, the pressing mechanism also includes a connecting plate, which is located on top of the carrier plate and parallel to the carrier plate. Several connecting posts at the top of the top rods slide through the connecting plate and are fixed with an anti-loosening nut at the top of the connecting plate. An adjusting screw with a turntable handle is threadedly fitted in the middle of the connecting plate. The bottom end of the adjusting screw passes through the connecting plate and is rotatably mounted on the carrier plate.

[0015] Furthermore, the pressing mechanism also includes an arc-shaped pressure plate, the top of which is connected to the connectors at the bottom of several push rods by a pin; pressure rollers are installed at equal intervals along the circumference of the tray at the bottom of the pressure plate.

[0016] Furthermore, a material positioning bracket consisting of three long rods is fixed in the middle of the front of the pressure adjustment chamber. Adjacent long rods are connected by a cross fixing block and are perpendicular to each other. One of the three long rods is vertically fixed to the front of the pressure adjustment chamber, while the other two are horizontally set on the top of the tray.

[0017] Furthermore, the unloading mechanism includes a stand installed on the workbench. A side-standing belt conveyor is mounted on the front end of the stand via a lifting frame. A lever is installed on the conveyor belt of the belt conveyor near the pallet. One end of the belt conveyor is located on the top of the pallet, while the other half of the belt conveyor extends beyond the pallet. A guide bar is installed on the support of the belt conveyor near the pallet. The guide bar is clearly angled, and the front end of the guide bar is located between adjacent support rings, with the height of the front end of the guide bar lower than the height of the support rings.

[0018] Beneficial effects:

[0019] This invention uses a circular turntable as the pallet. Utilizing the coordination between the chamfering mechanism and the pressing mechanism, it enables continuous automatic arc chamfering cutting of single boards. The entire cutting process only requires the operator to precisely place the material at the correct angle using the unloading positioning bracket during loading; the rest of the process is automated. Furthermore, the unloading mechanism, in conjunction with the pallet, enables automated unloading and material transfer, significantly improving the efficiency of chamfering the tail of the fan-shaped board. The circular pallet, with its curved edge corresponding to the cutting line at the tail of the board, helps the operator control the subsequent cutting path during unloading. The unloading positioning bracket assists in positioning the unloading angle, allowing the operator to place the board at the optimal angle, thus increasing board utilization and avoiding significant waste during cutting. Moreover, this equipment has lower requirements for the dimensional consistency of the triangular logs during board chamfering, and can adapt to different sizes of boards within the same batch. Compared to currently known arc chamfering machines, this device is more suitable for board processing manufacturers. Attached Figure Description

[0032] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0033] Example:

[0034] like Figure 1-5As shown, this embodiment provides a fan-shaped plate tail arc cutting machine, specifically including a worktable 1. A circular tray 6 is rotatably mounted on the top surface of the worktable 1. At the same time, a drive mechanism for driving the tray 6 to rotate is installed inside the worktable 1. In order to ensure that the tray 6 can remain relatively stable during rotation and provide relatively stable support for the arc cutting and chamfering of the plate tail, several annular guide rails 14 concentrically arranged with the tray 6 are installed on the top of the worktable 1. At the same time, several rollers 13 are installed around the circumference at the bottom of the tray 6 corresponding to the positions of each guide rail 14. The rollers 13 roll on the guide rails 14 at the corresponding positions to support the tray 6 to rotate smoothly on the worktable 1.

[0035] To achieve low-speed rotation of pallet 6 and ensure that workers have sufficient time to check the angle of the boards during the loading process, its drive mechanism mainly consists of a geared motor 5 and a planetary gear reducer 15. The output end of the geared motor 5 is connected to the power input end of the planetary gear reducer 15, and the output end of the planetary gear reducer 15 is connected to the center position of pallet 6. This ensures that pallet 6 rotates at low speed while increasing the torque of pallet 6 during rotation.

[0036] To achieve the rounded chamfering of the triangular plate's tail, a chip removal chamber 2, a working chamber 3, and a pressure adjustment chamber 4 are constructed sequentially from bottom to top on the side of the workbench 1 via a frame. The chip removal chamber 2, working chamber 3, and pressure adjustment chamber 4 are respectively equipped with a chip removal trough 9 for discharging wood chips, a chamfering mechanism 7 for cutting the tail of the triangular plate, and a pressure limiting mechanism 8 for pressing down on and limiting the board material. To facilitate the chamfering mechanism 7's cooperation with the pressure mechanism 8 in cutting the board, the working chamber 3 has an open design on the side closest to the workbench 1. The operator places the board to be processed onto the tray 6 at the corresponding angle. The tray 6 carries the board and rotates it, moving it to the position of the pressure mechanism 8, where the pressure mechanism 8 limits the board material. As the tray 6 continues to rotate carrying the board, the chamfering mechanism 7 rounds the tail of the board, and the cut wood chips and scraps fall into the chip removal trough 9 and are discharged from the outlet of the chip removal chamber 2.

[0037] To prevent the wooden boards from slipping on the pallet 6, and to ensure that the processed boards can be unloaded smoothly, several concentric support rings 10 of the same height are provided on the top of the pallet 6 from the inside out. The side of the support ring 10 used to support the boards has a toothed design.

[0038] like Figure 9-11As shown, in order to ensure that the pressing mechanism 8 can press down and limit the plate without affecting the plate's rotation as the tray 6 rotates, thus cooperating with the chamfering mechanism 7 to complete the rounded chamfer cutting of the tail, the pressing mechanism 8 specifically includes two support rods 801 mounted on the side wall frame of the pressing adjustment chamber 4. A carrier plate 802 is horizontally mounted on the two support rods 801. The carrier plate 802 is located on the side of the support rods 801 closest to the worktable 1, and several sleeves 8 are vertically arranged in the middle of the carrier plate 802. 03. A push rod 804 is slidably inserted into the inner side of each sleeve 803. The top end of the push rod 804 has a connecting post integrally formed, while the bottom end of the push rod 804 has a connector 807 integrally formed. A spring 808 is fitted on the outside of the push rod 804 between the connector 807 and the sleeve 803. At the same time, in order to enable the pressing mechanism 8 to adjust the height between the bottom end of the pressing mechanism 8 and the tray 6 according to the different thicknesses of the plates produced in batches, so that it can adapt to the limit of plates of different thicknesses.

[0039] The pressing mechanism 8 also includes a connecting plate 805, which is located on top of the carrier plate 802 and parallel to it. Several connecting posts at the top of the push rods 804 slide through the connecting plate 805, and an anti-loosening nut is fixed to the top of the connecting plate 805. An adjusting screw 806 with a turntable handle is threaded onto the middle of the connecting plate 805. The bottom end of the adjusting screw 806 passes through the connecting plate 805 and is rotatably mounted on the carrier plate 802. The pressing mechanism 8 also includes... An arc-shaped pressure plate 809 is connected at its top to the connectors 807 at the bottom of several push rods 804 via pins. Pressure rollers 810 are evenly spaced along the circumference of the tray 6 at the bottom of the pressure plate 809. When the height of the pressure rollers 810 needs to be adjusted, the adjusting screw 806 is rotated. Because the bottom end of the adjusting screw 806 is in rotational engagement with the carrier plate 802, they can only rotate horizontally. Meanwhile, the connecting plate 805 slides into several sleeves 803. The top of the push rod 804 slides through it. The push rod 804 itself is restricted by the sleeve 803 and can only slide up and down in the sleeve 803. Therefore, when the operator rotates the adjusting screw 806, the connecting plate 805 cannot rotate due to the limitation of the push rod 804. With the adjusting screw 806 in an unchanged position, the connecting plate 805 can only move up and down. The push rod 804 is always directed towards the tray 6 due to the force of the spring 808 at the bottom. Therefore, by rotating the adjusting screw 806, the height of the connecting plate 805 is changed, thereby adjusting the downward movement restriction position of the push rod 804 under the action of the spring 808, thus changing the height of the pressure plate 809. The pressure roller on the pressure plate 809 can press down and position the plate while rolling on the surface of the plate, ensuring that the plate can rotate normally with the tray 6 and complete the final rounded chamfering of the tail.

[0040] like Figure 6As shown, in order to achieve automatic unloading and transfer of the processed plates, an unloading mechanism 12 is also installed on the side of the top of the workbench 1 to unload the processed triangular plates and realize automatic unloading operation. The unloading mechanism 12 specifically includes a stand 121 installed on the workbench 1. A side-standing belt conveyor 123 is installed at the front end of the stand 121 through a lifting frame 122. A lever 124 is installed on the conveyor belt of the belt conveyor 123 near the pallet 6. One end of the belt conveyor 123 is located on the top of the pallet 6, while the other end of the belt conveyor 123 extends out of the pallet 6. The belt conveyor 123 is close to the pallet 6. A guide bar 125 is installed on one side of the bracket. The guide bar 125 is clearly angled and its front end is located between adjacent support rings 10. The height of the front end of the guide bar 125 is lower than the height of the support rings 10. When the processed board moves to the unloading mechanism 12 position with the pallet 6, the board that arrives at the unloading mechanism 12 position first is pushed by the successively delivered boards, so that the board that arrives at the unloading mechanism 12 position first is transferred to the guide bar 125 and contacts the conveyor belt on the belt conveyor 123. Under the continuous operation of the belt conveyor 123, the pusher block 124 pushes the processed board out from the end of the board from the guide bar 125.

[0041] like Figure 7-8 As shown, according to the processing requirements of the rounded corner at the tail end of the board, the angle of the rounded corner needs to be adjusted adaptively for different batches of board specifications. In order to meet this processing requirement, the chamfering mechanism 7 includes a bracket 701 installed on the side wall frame of the working chamber 3, and a long strip-shaped notch 705 is opened in the middle of the bracket 701. A base 702 for installing the chamfering motor 703 is hinged to the middle of the bracket 701 near the front end. A cutting disc 704 is installed at the output end of the chamfering motor 703 installed on the base 702. The upper edge of the cutting disc 704 is close to the edge of the tray 6. At the same time, a T-shaped adjusting rod 706 is rotatably installed at the tail of the base 702. The lower end of the adjusting rod 706 is located inside the notch and is fixed inside the notch by two threaded adjusting nuts 707. By adjusting the position of the adjusting nuts 707 on the adjusting rod 706, the pitch angle of the carrier plate 802 can be adjusted.

[0042] like Figure 1-2As shown, to help operators place materials more accurately, a material placement bracket 11 consisting of three long rods is fixed in the middle of the front of the pressure adjustment chamber 4. Adjacent long rods are connected by cross-shaped fixing blocks and are perpendicular to each other. One of the three long rods is vertically fixed to the front of the pressure adjustment chamber 4, while the other two are horizontally set on the top of the tray 6. The intersection point of these two horizontally set long rods corresponds to the upper and lower positions of the center point of the tray 6. A certain gap is maintained between these two horizontal long rods and the tray 6 to facilitate the placement of the board. It should be further explained that the main function of the material placement bracket 11 is to provide the operator with a reference point for the center line of the tray 6 so that the operator can align the angle of the board when placing it.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
