Description

Technical Field

[0001] The invention relates to a square plate edge planing device used for producing wooden products. Background Art

[0002] Wood products, especially solid wood products, require first cutting of the wood boards during the production process, then fine processing of the wood boards, and then assembly.

[0003] Planing of wood products is one of the processing methods. The existing technology mainly uses a handheld planer. The handheld planer drives the cutter head to rotate at high speed through a motor, and uses the cutter head to complete the planing. In this processing method, the wood is polished to form relatively fine droplets, resulting in a poor workshop environment. In addition, these flying wood chips are easily inhaled by the staff, posing a safety hazard. They are also easily ignited after entering the equipment and causing a fire.

[0004] Secondly, this method of hand-held planing requires support, otherwise it is difficult to make the planed edge straight. It has certain requirements for operation, and the efficiency of planing is relatively low.

[0005] The most traditional process is manual planing with a planer, which has extremely low operating efficiency and higher requirements for carpenters.

[0036] See also Figure 1 The device shown is a square board planing device for producing wood products, comprising a frame 1, wherein both ends of the frame 1 are bent vertically upward to form a vertical frame 2, a first horizontal frame 3 and a second horizontal frame 4 are installed through the vertical frame 2, the first horizontal frame 3 is parallel to the second horizontal frame 4, a planing mechanism 5 is movably installed between the first horizontal frame 3 and the second horizontal frame 4, a clamping device 6 is slidably installed through the first horizontal frame 3, and the clamping device 6 is located between the planing mechanisms 5 on both sides; a "∧"-shaped guide plate 99 is arranged inside the frame 1, and the guide plate 99 is located below the planing mechanism 5 and the clamping device 6.

[0037] In the technical solution, the first horizontal frame 3 and the second horizontal frame 4 arranged in parallel provide guiding and supporting functions.

[0038] Two planing mechanisms 5 are provided, and the two planing mechanisms operate independently, so the position of the planing mechanism 5 on one side can be adjusted individually, so as to make reasonable adjustments according to the required size of the planked wood board.

[0039] In the above technical solution, the clamping device 6 reciprocates along the first horizontal frame 3, and contacts the edge planing mechanism 5 on both sides twice in one reciprocating movement, which greatly improves the edge planing efficiency.

[0040] The wood chips are discharged by the guide plate 99 .

[0041] See also Figure 2 As shown, two first through grooves 31 are symmetrically arranged on the side of the first cross frame 3, and guide holes 32 connected to the first through grooves 31 are arranged at the two end faces of the first cross frame 3. The planing mechanism 5 slides laterally along the first through grooves 31 and is guided by the guide holes 32.

[0042] See also Figure 2 As shown, the side of the second cross frame 4 is symmetrically provided with a second through slot 41 corresponding to the first through slot 31, and a screw is rotatably engaged in the second through slot 41, one end of the screw extends to the outside of the second cross frame 4, and the end is engaged with a servo motor 43, the servo motor 43 is fixed to the second cross frame 4, and is connected to drive the screw, the planing mechanism 5 is engaged in the second through slot 41, and is driven to slide by the screw.

[0043] In the above technical solution, the planing mechanism 5 is supported by the first horizontal frame 3 and the second horizontal frame 4 to move in translation, and the displacement is driven by the servo motor 43 in cooperation with the screw rod, so the moving position is accurate.

[0044] The servo motor 43 is controlled by an independent servo system, and the feeding amount each time can be preset to facilitate the edge planing mechanism 5 to plane the edge step by step.

[0045] See also Figure 2 and Figure 3 As shown, the planing mechanism 5 includes a first slider 51, a second slider 52, a guide rod 53, a tool holder 54 and a double-edged tool 55. The first slider 51 is slidably fitted in the first through groove 31, and the second slider 52 is slidably fitted in the second through groove 41. A first guide rod 56 is provided on the outer side of the first slider 51. The first guide rod 56 passes through the guide hole 32 and slides along the axial direction of the guide hole 32. A threaded hole 57 matching the screw rod 42 is penetrated through the side of the second slider 52. The guide rod 53 is installed between the first slider 51 and the second slider 52. The tool holder 54 is sleeved on the guide rod 53. The double-edged tool 55 is installed through the tool holder 54 and corresponds to the clamping device 6.

[0046] In the above technical solution, the first slider 51 and the second slider 52 cooperate with the first cross frame 3 and the second cross frame 4 respectively to realize the sliding support of the guide rod 53, and the second slider 52 is driven by the screw to move to complete the feeding of the bidirectional tool 55.

[0047] In a single movement of the clamping device 6, the second slider 52 moves N pitches, and the moving distance of one pitch is 0.1 mm. That is to say, in one reciprocating motion of the clamping device 6, the second slider 52 needs to move 2N pitches, wherein before the wooden product contacts the double-edged tool 55, the second slider 52 moves N pitches driven by the screw, so that the wooden product contacts one of the blades of the double-edged tool 55 when moving, completing one planing operation. When the clamping device 6 is reset, the second slider 52 moves N pitches again driven by the screw, so that when the clamping device 6 is reset, the other blade of the double-edged tool 55 contacts the reset wooden product again. One reciprocating motion of the clamping device 6 completes two planing operations, doubling the planing efficiency.

[0048] N is preset by the servo motor, and N ranges from 1 to 10.

[0049] See also Figure 3 As shown, one end of the guide rod 53 is inserted into the second slider 52, and a bearing 510 is provided between the guide rod 53 and the second slider 52. An angle rotation motor 511 is provided at the end of the first slider 51 away from the guide rod 53, and a socket 551 is provided on the output shaft of the angle rotation motor 511. The other end of the guide rod 53 is inserted into the socket 551 and fixed. Under the action of the angle rotation motor 511, the guide rod 53 rotates, driving the tool holder 54 to rotate a preset angle.

[0050] In the above technical solution, angled planing can be achieved. In actual operation, it is necessary to determine whether the self-locking ability of the angle rotating motor 511 can be locked during the planing process based on the hardness of the wood product. When the double-edged tool contacts the wood product, if the guide rod 53 rotates passively, it means that the self-locking ability of the angle rotating motor 511 is insufficient. At this time, it is necessary to screw a bolt into the top of the first slider 51. The bolt actively locks the output shaft of the angle rotating motor 511 to complete the reinforcement so as to effectively complete the angle planing.

[0051] See also Figure 4 As shown, a positioning groove 533 is provided on the outer wall of the guide rod 53, and the positioning groove 533 passes through the end away from the second slider 52. A positioning slider matching the positioning groove 533 is provided on the inner wall of the knife seat 54, and a locking bolt 542 is screwed into the outer wall of the knife seat 54. The locking bolt 542 is locked with the guide rod 53 after being screwed inward.

[0052] In the above technical solution, the knife seat 54 is slidable, which is convenient for adjusting the position and also convenient for later maintenance.

[0053] See also Figure 4As shown, two limit sleeves 534 are provided on the guide rod 53, and a first locking bolt 535 is cooperated between the limit sleeve 534 and the guide rod 53. A spring 536 is provided on the guide rod 53, and the spring 536 acts between the limit sleeve 534 and the knife seat 54. When the locking bolt 542 is loosened, the knife seat 54 slides along the guide rod 53 and is reset by the rebound of the spring 536.

[0054] In the above technical solution, the spring 536 is provided to provide the knife seat 54 with a space for elastic movement. When the double-edged tool contacts the wood product, the compression of the spring 536 allows the double-edged tool to move in a buffered manner, thereby reducing the excessive movement speed of the wood product, which would cause the wood product to break and break after colliding with the double-edged tool.

[0055] See also Figure 2 As shown, the clamping device 6 includes a clamping seat 61, which is U-shaped and has a clamping opening 62. A second guide rod 62 is arranged on the outer side of the clamping seat 61, and the second guide rod 62 passes through the first cross frame 3. A linear bearing 63 is matched between the second guide rod 62 and the first cross frame 3, and the second guide rod 62 slides along the linear bearing 63. An electric push rod 64 is installed on the outer side of the first cross frame 3, and the movable end of the electric push rod 64 passes through the first cross frame 3 and is connected to the clamping seat 61. The clamping seat 61 is flush with the planing mechanism 5.

[0056] In the above technical solution, the clamping seat 61 is driven to move back and forth by the operation of the electric push rod 64, and the servo motors 43 on both sides are cooperated to feed, so as to complete the planing of the wooden product.

[0057] See also Figure 5 and Figure 6 As shown, a first electric push rod 610 is installed at the bottom of the clamping seat 61, and the movable end of the first electric push rod 610 is inserted upward into the clamping opening 62, and a lower clamping plate 611 is rotatably engaged at this end. A clamping shaft device 7 is provided at the upper end of the clamping seat 61, and a first angle rotating motor 612 is installed at the upper end of the clamping shaft device 7. The output shaft 661 of the first angle rotating motor 612 passes through the clamping shaft device 7 and is inserted into the clamping opening 62, and an upper clamping plate 613 is fixedly installed at this end. The planed wood board is clamped between the lower clamping plate 611 and the upper clamping plate 613. During the planing process, the output shaft of the first angle rotating motor 612 is locked by the clamping shaft device 7.

[0058] In the above technical solution, a first electric push rod 610 is used to drive the lower clamping plate 611 to move, and the clamping of the wooden product to be processed is completed through the cooperation of the lower clamping plate 611 and the upper clamping plate 613. In actual application, the upper surface of the lower clamping plate 611 and the lower surface of the upper clamping plate 613 are processed to form anti-slip knurled patterns to increase the contact friction with the wooden product, so as to prevent the wooden product from shifting in position when moving with the clamping seat 61.

[0059] The first angle rotating motor 612 itself has a locking function. In order to further improve the stability after the angle rotation, an independently designed clamping shaft device 7 is installed to clamp the output shaft 661 of the first angle rotating motor 612 to keep it in place during the planing process to avoid rotation.

[0060] See also Figure 7 As shown, the clamping shaft device 7 includes a shell 71, and micro electric push rods 72 are arranged opposite to each other on the outer wall of the shell 71. The two micro electric push rods 72 are on the same diameter line of the shell 71 and are perpendicular to the output shaft of the first angle rotation motor 612. The movable end of the micro electric push rod 72 is provided with a clamping shaft plate 73. The clamping shaft plate 73 is arc-shaped, and a rubber clamp block 74 is provided on the inner arc surface. A passive locking block 75 is provided on the output shaft of the first angle rotation motor 612. The passive locking block 75 is fixed to the output shaft of the first angle rotation motor 612, and anti-slip grooves 76 are distributed in an annular manner on the outer wall of the passive locking block 75. After the micro electric push rod 72 is ejected, the rubber clamp block 74 holds the passive locking block 75, and the position of the passive locking block 75 is fixed at this time.

[0061] In the above technical solution, the position locking of the output shaft 661 is achieved by means of the output of the micro electric push rods 72 on both sides and the rubber clamping block 74 locking the passive locking block 75 .

[0062] When the wooden product needs to be rotated 90 degrees, the micro electric push rod 72 retracts to release the clamping of the output shaft 661. At this time, the first angle rotation motor can rotate to actively adjust the placement angle of the wooden product through the upper clamping plate 613 to complete the planing of the remaining two edges, eliminating the step of manual secondary clamping and speeding up the operation efficiency.
