[0002] Furniture refers to the essential equipment and facilities for humans to maintain normal life, engage in production practice and carry out social activities. Furniture has also been continuously developing and innovating with the times. Today, there are many categories, different materials, complete varieties and different uses. It is an important foundation for establishing a working and living space.

[0003] Furniture is a wooden product that is processed and assembled based on boards. When manufacturing furniture, the boards need to be processed first, such as cutting, drilling, and grooving. When grooving the boards, a cutting saw is used to process the surface of the fixed boards so that grooves of a certain depth are formed on the surface of the boards.

[0004] When double-sided grooving of a plate is performed, one side needs to be processed first and then the processed surface needs to be flipped over and processed again. After flipping, the position of the previously dug groove cannot be accurately located, resulting in deviations in the grooves on both sides of the plate. The depth of the groove cannot be accurately controlled, resulting in inaccurate groove dimensions and even the plate being scrapped due to excessive grooving. Therefore, the existing needs are not met. We have proposed a grooving device and method for furniture manufacturing plates. Summary of the invention

[0018] A grooving method for a furniture manufacturing plate grooving device, the grooving method comprising the following steps:

[0019] (A) First, place the plate in the middle of the eight clamping hydraulic rods, and use the eight clamping hydraulic rods to fix and clamp the plate. After the plate is clamped and fixed, determine the depth of the plate groove. After determination, turn on the device power and start the device. After the device is started, the distance sensor will always detect the position of the protection distance adjustment block. At this time, the staff can adjust the position of the protection distance adjustment block on the outside of the bottom end of the hanging rod according to the depth of the groove, so that the distance between the protection distance adjustment block and the distance sensor is the length of the protection adjustment column that is about to move down. After the adjustment is completed, the protection distance adjustment block is fastened to the outside of the hanging rod with screws;

[0020] (B) After the device is started, the electromagnet will disconnect the power supply. At this time, the connection spring will elastically reset and separate the metal U-shaped connection block from the electromagnet. At this time, the two ends of the metal U-shaped connection block will extend from the inside of the connecting cylinder and be plugged into the plug-in slots on the outer surface of the end where the transmission shaft and the connecting shaft are connected to the connecting cylinder. At this time, the connecting shaft, the connecting cylinder and the transmission shaft can rotate synchronously. After the drive motor is powered on, it drives the grooving shaft to drive the grooving saw blade and the transmission bevel gear to rotate;

[0021] (C) When the transmission bevel gear rotates, it will drive the power bevel gear meshing with it to rotate, causing the connecting shaft, connecting cylinder and transmission shaft to rotate. Then the switching bevel gear will rotate with the transmission shaft and drive the conversion bevel gear, conversion double-headed worm and two synchronous turbines to rotate synchronously. When the synchronous turbine rotates, it will drive the adjustment double-headed worm and the adjustment turbine to rotate, causing the adjustment screw to rotate. At this time, the four adjustment turbines and the four adjustment screws rotate in the same direction.

[0022] (D) When the adjusting screw rotates, it will be transmitted through the threaded hole at the top of the protective adjusting column, so that the protective adjusting column moves along the axis of the adjusting screw and the bottom end of the vertical tube extends. During the downward movement of the protective adjusting column, the sensing contact rod will be pressed downward and the sensing contact rod will stretch the reset spring until the pressure sensor on the bottom surface of the top of the sensing contact rod contacts the surface of the protective distance adjustment block. At this time, it indicates that the protective adjusting column moves down by a specified length. Then the electromagnet is energized and magnetically attracts the metal U-shaped connecting block, so that the metal U-shaped connecting block shrinks into the connecting cylinder and compresses the connecting spring, separating the connecting cylinder and the connecting shaft rod. At this time, the protective adjusting column stops extending out of the vertical tube. At this time, the vertical projection area between the end of the protective adjusting column extending out of the vertical tube and the grooving saw blade is the depth dimension of the groove on the plate surface.

[0023] (E) After the groove depth is determined, the four longitudinal moving motors and the two transverse moving motors are started synchronously, so that the longitudinal moving slider moves outside the longitudinal moving screw rod and the transverse moving slider moves outside the transverse moving screw rod, and the two groove saw blades are moved to the start position of the groove on the plate surface;

[0024] (F) Next, the lifting electric push rod drives the lifting block and the grooving saw blade, which is driven by the driving motor and the grooving shaft and rotates, to approach the plate, and the rotating grooving saw blade is used to groove the plate until the end face of the protective adjustment column extending out of the vertical tube contacts the plate. At this time, the depth of the groove dug by the grooving saw blade is the depth of the groove required for processing, and the depth of the groove can be accurately controlled. The two grooving saw blades located above and below the plate are used for synchronous cutting to ensure that there is no position deviation between the grooves on both sides of the plate. Beneficial Effects

[0025] 1. The present invention can simultaneously dig grooves on the plate, so that there will be no position deviation of the grooves on both sides of the plate, and the depth of the grooves can be determined by the depth protection component before digging the grooves, so that when the plate is grooved, the saw blade will not exceed the processing depth of the groove on the surface of the plate, thereby ensuring the dimensional accuracy of the groove after processing and avoiding the plate being scrapped due to excessive groove digging;

[0026] 2. In the process of starting the plate grooving saw blade and approaching the plate, the present invention can connect the connecting shaft and the transmission shaft by connecting the cylinder, the metal U-shaped connecting block, the electromagnet, and the connecting spring, and adjust the length of the protective adjustment column, so that the device can automatically protect according to the height of the grooving, and can adapt to the protection needs when processing grooves of different depths.

The two lifting blocks 501 are respectively fixed to the movable ends of the two lifting electric push rods, and a power conversion module 6 is arranged above the connecting shaft 511;

[0040] The power conversion module 6 includes a transmission shaft 601 , a switching bevel gear 602 , a connecting cylinder 603 , a metal U-shaped connecting block 604 , an electromagnet 605 and a connecting spring 606 .

[0041] Among them, one end of the groove rotating shaft 506 is connected to the driving motor 505 through a fixing pin, the other end of the groove rotating shaft 506 passes through the driving motor protection housing 502 and a groove saw blade 4 is arranged on the outer side of the end, a groove saw blade protection housing 3 is arranged above the groove saw blade 4, the groove saw blade protection housing 3 is fixedly connected to the lifting block 501 close to it, the transmission bevel gear 508 is fixed on the outer surface of the groove rotating shaft 506 and meshes with the power bevel gear 507 at the bottom end of the connecting shaft 511, the transmission shaft 601 is coaxial with the connecting shaft 511, and the switching bevel gear 602 at the top is meshed with the conversion bevel gear 509;

[0042] Suspension rings are fixedly provided on the outer sides of the ends where the transmission shaft 601 and the connecting shaft 511 are connected to the connecting cylinder 603. The edges of the suspension rings are clamped in the inner wall of the driving motor protection shell 502 and the outer surface is inlaid with balls. The suspension rings are in rolling contact with the driving motor protection shell 502 through the balls. A threaded hole is provided at the top of the protection adjustment column 504. The bottom end of the adjusting screw 515 is screwed into the protection adjustment column 504 from the top of the threaded hole and is transmitted to the protection adjustment column 504 through threads.

[0043] By adopting the above technical solution, when the transmission bevel gear 508 rotates, it can drive the power bevel gear 507 and the connecting shaft 511 to rotate, so that the connecting cylinder 603 drives the transmission shaft 601 and the switching bevel gear 602 to rotate, thereby making the four protective adjustment columns 504 rotate synchronously, thereby adjusting the length of the four protective adjustment columns 504 extending out of the vertical pipe 503, and realizing the control of the trenching depth.

[0044] Plug-in slots are provided on the outer sides of the ends where the transmission shaft 601 and the connecting shaft 511 are connected to the connecting cylinder 603. Both ends of the metal U-shaped connecting block 604 penetrate the inner wall of the connecting cylinder 603 and are respectively engaged in the two plug-in slots. A storage power supply is embedded on the upper end surface of the connecting cylinder 603. The storage power supply is connected to the electromagnet 605 through an electric wire. There is magnetic attraction between the metal U-shaped connecting block 604 and the electromagnet 605. The connecting spring 606 is made of copper or aluminum. The magnetic attraction of the metal U-shaped connecting block 604 to the electromagnet 605 is greater than the sum of the elastic forces of all the connecting springs 606.

[0045] By adopting the above technical solution, the connecting shaft 511, the connecting cylinder 603 and the transmission shaft 601 can be rotated through the two ends of the metal U-shaped connecting block 604, so that the connecting shaft 511 can drive the connecting cylinder 603 and the transmission shaft 601 to rotate. On the contrary, when the metal U-shaped connecting block 604 shrinks into the connecting cylinder 603, the connecting shaft 511 will not drive the connecting cylinder 603 and the transmission shaft 601 to rotate during rotation.

[0046] Among them, two symmetrically distributed adjustable precise distance measuring structures 7 are hung on both sides of the lifting block 501, and the adjustable precise distance measuring structure 7 includes a hanging rod 701, a distance measuring sensor 702, a protection distance adjusting block 703, a reset spring 704 and an induction contact rod 705.

A return spring 704 is arranged below the protection distance adjustment block 703, and a sensing contact rod 705 is arranged below the return spring 704. The two ends of the return spring 704 are respectively fixedly connected to the bottom surface of the protection distance adjustment block 703 and the surface of the sensing contact rod 705. One end of the sensing contact rod 705 is located above the end of the protection distance adjustment block 703 and the other end is located below the protection adjustment column 504. A pressure sensor is arranged on the bottom surface of the end of the sensing contact rod 705 located above the protection distance adjustment block 703.

[0047] By adopting the above technical solution, the downward movement distance of the protection adjustment column 504 can be accurately controlled to avoid the protection adjustment column 504 moving down too much or too little, which will cause defects in the size processing of the groove.

[0048] The transverse moving screw rod passes through the middle of the two ends of the transverse moving slider, and the longitudinal moving screw rod passes through the middle of the longitudinal moving slider. The transverse moving screw rod and the transverse moving slider, the longitudinal moving screw rod and the longitudinal moving slider are all transmitted by threads. Guide rods are arranged on both sides of the transverse moving screw rod and both sides of the longitudinal moving screw rod, and the guide rods pass through the transverse moving slider and the longitudinal moving slider.

[0049] By adopting the above technical solution, when the transverse moving screw and the longitudinal moving screw are rotated by the guide rod, the transverse moving slider and the longitudinal moving slider can only move linearly along the straight direction, and cannot rotate with the transverse moving screw and the longitudinal moving screw.

[0050] A grooving method for a furniture manufacturing plate grooving device, the grooving method comprising the following steps:

[0051] (A) First, place the plate in the middle of the eight clamping hydraulic rods, and use the eight clamping hydraulic rods to fix and clamp the plate. After the plate is clamped and fixed, determine the depth of the plate groove. After determination, turn on the power of the device and start the device. After the device is started, the distance sensor 702 will always detect the position of the protection distance adjustment block 703. At this time, the staff can adjust the position of the protection distance adjustment block 703 on the outside of the bottom end of the hanging rod 701 according to the depth of the groove, so that the distance between the protection distance adjustment block 703 and the distance sensor 702 is the length of the protection adjustment column 504 that is about to move down. After the adjustment is completed, the protection distance adjustment block 703 is fastened to the outside of the hanging rod 701 with screws;

[0052] (B) After the device is started, the electromagnet 605 will disconnect the power supply, at which time the connection spring 606 will elastically reset and separate the metal U-shaped connection block 604 from the electromagnet 605. At this time, the two ends of the metal U-shaped connection block 604 will extend from the inside of the connecting cylinder 603 and be inserted into the plug-in slots on the outer surface of the end where the transmission shaft 601 and the connecting shaft 511 are connected to the connecting cylinder 603. At this time, the connecting shaft 511, the connecting cylinder 603 and the transmission shaft 601 can rotate synchronously. After the driving motor 505 is powered on, it drives the grooving shaft 506 to drive the grooving saw blade 4 and the transmission bevel gear 508 to rotate;

[0053] (C) When the transmission bevel gear 508 rotates, it will drive the meshing power bevel gear 507 to rotate, so that the connecting shaft 511, the connecting cylinder 603 and the transmission shaft 601 rotate, and then the switching bevel gear 602 will rotate with the transmission shaft 601 and drive the conversion bevel gear 509, the conversion double-headed worm 510 and the two synchronous turbines 512 to rotate synchronously. When the synchronous turbine 512 rotates, it will drive the adjustment double-headed worm 513 and the adjustment turbine 514 to rotate, so that the adjustment screw 515 rotates. At this time, the four adjustment turbines 514 and the four adjustment screws 515 rotate in the same direction;

[0054] (D) When the adjusting screw 515 rotates, it will be transmitted through the threaded hole at the top of the protection adjustment column 504, so that the protection adjustment column 504 moves along the axis of the adjusting screw 515 and the bottom end of the standpipe 503 extends. During the downward movement of the protection adjustment column 504, the sensing contact rod 705 is pressed downward and the sensing contact rod 705 stretches the reset spring 704 until the pressure sensor on the bottom surface of the top of the sensing contact rod 705 contacts the surface of the protection distance adjustment block 703. At this time, it indicates that The protection adjustment column 504 moves down a specified length, and then the electromagnet 605 is energized and magnetically attracts the metal U-shaped connection block 604, so that the metal U-shaped connection block 604 shrinks into the connection cylinder 603 and compresses the connection spring 606, and separates the connection cylinder 603 and the connection shaft 511. At this time, the protection adjustment column 504 stops extending out of the vertical pipe 503. At this time, the vertical projection area between the end of the protection adjustment column 504 extending out of the vertical pipe 503 and the groove saw blade 4 is the depth dimension of the groove on the surface of the plate;

[0055] (E) After the groove depth is determined, the four longitudinal moving motors and the two transverse moving motors are started synchronously, so that the longitudinal moving slider moves outside the longitudinal moving screw rod and the transverse moving slider moves outside the transverse moving screw rod, and the two groove saw blades 4 are moved to the start position of the groove on the plate surface;

[0056] (F) Next, the lifting electric push rod drives the lifting block 501 and the grooving saw blade 4 which is driven and rotated by the driving motor 505 and the grooving shaft 506 to approach the plate, and the rotating grooving saw blade 4 is used to groove the plate until the protective adjustment column 504 extends out of the end face of the vertical tube 503 and contacts the plate. At this time, the depth of the groove dug by the grooving saw blade 4 is the depth of the groove required for processing, and the depth of the groove can be accurately controlled. The two grooving saw blades 4 located above and below the plate are used to cut synchronously to ensure that there is no position deviation between the grooves on both sides of the plate.

2. A grooving method for a furniture manufacturing plate grooving device according to claim 1, characterized in that: The trenching method comprises the following steps: (A) First, a plate is placed in the middle of eight clamping hydraulic rods, and the plate is fixed and clamped by the eight clamping hydraulic rods. After the plate is clamped and fixed, the depth of the plate groove is determined. After the determination, the device power is turned on and the device is started. After the device is started, the distance sensor (702) will always detect the position of the protection distance adjustment block (703). At this time, the staff can adjust the position of the protection distance adjustment block (703) on the outer side of the bottom end of the hanging rod (701) according to the depth of the groove, so that the distance between the protection distance adjustment block (703) and the distance sensor (702) is the length of the protection adjustment column (504) that is about to move down. After the adjustment is completed, the protection distance adjustment block (703) is fastened to the outer side of the hanging rod (701) with screws; (B) After the device is started, the electromagnet (605) will disconnect the power supply, at which time the connecting spring (606) will elastically reset and separate the metal U-shaped connecting block (604) from the electromagnet (605), at which time the two ends of the metal U-shaped connecting block (604) will extend from the inside of the connecting cylinder (603) and be inserted into the plug-in slots on the outer surface of the end where the transmission shaft (601) and the connecting shaft (511) are connected to the connecting cylinder (603), at which time the connecting shaft (511), the connecting cylinder (603) and the transmission shaft (601) can rotate synchronously, and after the driving motor (505) is powered on, it drives the grooving shaft (506) to drive the grooving saw blade (4) and the transmission bevel gear (508) to rotate; (C) When the transmission bevel gear (508) rotates, it drives the power bevel gear (507) meshing with it to rotate, so that the connecting shaft (511), the connecting cylinder (603) and the transmission shaft (601) rotate, and then the switching bevel gear (602) rotates with the transmission shaft (601) and drives the conversion bevel gear (509), the conversion double-headed worm (510) and the two synchronous turbines (512) to rotate synchronously. When the synchronous turbine (512) rotates, it drives the adjustment double-headed worm (513) and the adjustment turbine (514) to rotate, so that the adjustment screw (515) rotates. At this time, the four adjustment turbines (514) and the four adjustment screws (515) rotate in the same direction; (D) When the adjusting screw rod (515) rotates, it will be transmitted through the threaded hole at the top of the protection adjustment column (504), so that the protection adjustment column (504) moves along the axis of the adjusting screw rod (515) and the bottom end of the standpipe (503) extends. During the downward movement of the protection adjustment column (504), the sensing contact rod (705) is pressed downward and the sensing contact rod (705) stretches the reset spring (704) until the pressure sensor on the bottom surface of the top of the sensing contact rod (705) contacts the surface of the protection distance adjustment block (703), indicating that the protection is closed. The adjustment column (504) moves downward by a specified length, and then the electromagnet (605) is energized and magnetically attracts the metal U-shaped connection block (604), so that the metal U-shaped connection block (604) contracts and enters the connection cylinder (603) and compresses the connection spring (606), thereby separating the connection cylinder (603) and the connection shaft (511). At this time, the protective adjustment column (504) stops extending out of the vertical tube (503). At this time, the vertical projection area between the end of the protective adjustment column (504) extending out of the vertical tube (503) and the groove saw blade (4) is the depth dimension of the groove on the surface of the plate; (E) After the groove depth is determined, the four longitudinal moving motors and the two transverse moving motors are started synchronously, so that the longitudinal moving slider moves outside the longitudinal moving screw rod and the transverse moving slider moves outside the transverse moving screw rod, and the two groove saw blades (4) are moved to the start position of the groove on the surface of the plate; (F) Next, the lifting electric push rod drives the lifting block (501) and the groove saw blade (4) driven by the driving motor (505) and the groove shaft (506) to rotate and approach the plate, and the plate is grooved by the rotating groove saw blade (4) until the end face of the protective adjustment column (504) extending out of the vertical pipe (503) contacts the plate. At this time, the depth of the groove dug by the groove saw blade (4) is the depth of the groove required for processing, and the depth of the groove can be accurately controlled. The two groove saw blades (4) located above and below the plate are used for cutting simultaneously to ensure that there is no position deviation between the grooves on both sides of the plate.
