Description

Technical Field

[0001] The invention belongs to the technical field of furniture processing, and in particular relates to a turning mechanism and a turning method for gluing furniture panels. Background Art

[0002] Furniture is made of various boards that are cut and assembled using connectors. It has been continuously developed and innovated with the times. Today, furniture comes in many categories, with different materials, complete varieties, and different uses. At the same time, furniture is an indispensable category of tools and facilities for humans to maintain normal life, engage in production practice, and carry out social activities.

[0003] In the process of furniture production and processing, boards of different thicknesses are needed. In order to obtain the required board thickness, it is often necessary to apply glue to the boards manually or with a glue coating machine, and bond different numbers of boards together to obtain boards of different thicknesses to suit the use of different parts of the furniture.

[0004] At present, when the existing glue coating machines are coating the plates, most of them can only coat the plates with glue on one side. After coating one side, the staff needs to remove the clamped plate, turn it over, clamp it again, and continue coating the other side with glue. The operation is relatively cumbersome, which increases the workload of the staff, resulting in a long time spent on coating the plates, affecting the processing efficiency of the plate coating operation. Moreover, after coating, if the plates are not bonded in time, the glue will dry and harden, affecting the bonding effect of the plates.

[0005] Therefore, we designed a flipping mechanism and flipping method for gluing furniture panels to solve the above problems. Summary of the invention

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0010] In the above structure, the clamping mechanism is used to clamp and fix both sides of the plate to be coated with glue, so as to facilitate the coating of glue on the plate. Under the threaded cooperation between the moving block and the second screw, it is convenient to adjust the moving block to move along the direction of the second screw. Under the action of the fixed rod, the rack is driven to move synchronously. Combined with the meshing action of the rack and the gear, and the rotation cooperation between the support shaft and the fixed plate, combined with the disc, the clamping mechanism is driven to rotate, and then the clamped plate is driven to rotate with the support shaft as the center, until the disc drives the extrusion block to contact the pressure sensor on the lower side, completing the flipping of the plate, which is convenient for coating the other side of the plate with glue. There is no need for the staff to manually flip the plate, which effectively improves the processing efficiency of gluing the plate.

[0011] The clamping mechanism includes a mounting plate, which is fixed on the front surface of the disc. A slide groove is provided on the side of the mounting plate away from the disc. A first screw rod is arranged in the slide groove. Two sliders are threadedly arranged on the first screw rod. The thread directions of the central threaded holes of the two sliders are opposite. A clamping plate is fixed on the outer side of the slider.

[0012] The clamping member includes a vertical plate, a screw, a movable block, a connecting rod, a movable plate, a piston rod, a spring and an extrusion plate. The two vertical plates are respectively fixed on the sides of the two clamping plates away from each other. The screw is rotatably connected to one side surface of the vertical plate. The movable block is threaded on the screw. The movable plate is movably arranged on the side of the vertical plate away from the screw. The two connecting rods are fixedly connected between the movable block and the movable plate, and two round holes are penetrated on the surface of the vertical plate, and the connecting rod is movably matched with the round holes.

One end of the piston rod close to the clamping plate is fixedly connected to the extrusion plate, and several springs are fixedly connected between the movable plate and the extrusion plate. A pull ring is fixed on the end of the piston rod away from the extrusion plate.

[0014] A baffle is fixed on the sides of the two clamping plates that are close to each other, and the baffle is arranged on the side close to the slider. Guide grooves are opened on both sides of the inner wall of the slide groove, and guide blocks are fixed on the two side surfaces of the slider. The guide blocks are movably matched with the guide grooves. A first motor is installed at one end of the mounting plate, and the output end of the first motor is connected to one end of the first screw rod.

[0015] Guide rods are arranged on both sides of the second screw rod, the guide rods penetrate the moving block, and the moving block and the guide rods are slidably matched, a second motor is installed at one end of the fixed block, and the output end of the second motor is connected to one end of the second screw rod.

[0016] A T-shaped groove of an annular structure is provided on one side of the fixing plate close to the disc, a plurality of T-shaped blocks are slidably arranged in the T-shaped groove, and one end of the T-shaped block close to the outer side is fixedly connected to the disc, and a controller is installed on the top of the fixing plate.

[0017] A notch is provided on the fixed platform, and two supporting frames are relatively fixed at the bottom of the fixed platform.

A discharge pipe is connected to the bottom of the collecting hopper, and a valve is installed on the discharge pipe. A heating plate is arranged on the outer wall and the bottom of the collecting hopper.

[0018] A flipping method comprises the following steps:

[0019] Step 1: First, place the plate to be coated with glue between the two clamping plates, and start the first motor. Under the action of the first screw rod, the two sliders are driven to approach each other, and the rear end of the plate is abutted against the baffle until the two clamping plates are clamped on both sides of the plate, and the two sides of the plate are clamped and fixed, and then go to step 2;

[0020] Step 2: Apply glue to the upward side of the plate. After the glue is applied, press the outer plate onto the plate coated with glue, and rotate the screw on the upper side, combined with the movable block and the connecting rod, to drive the movable plate to move to the upper side of the plate. Under the elastic action of the spring, the extrusion plate is pressed toward the plate, so that the two plates are tightly pressed together, and then proceed to step 3;

[0021] Step 3: Start the second motor. Under the action of the second screw, combined with the moving block and the fixed rod, the rack is driven to move along the direction of the second screw. Under the meshing action of the gear and the rack, the support shaft is driven to rotate. In conjunction with the disc and the clamping mechanism, the plate is driven to rotate synchronously until the extrusion block contacts the pressure sensor on the lower side, realizing the flipping of the plate, and continuing to apply glue to the other side of the plate.

[0022] The present invention has the following beneficial effects:

[0023] The present invention facilitates the clamping and fixing of both sides of the plate to be glued by the clamping mechanism, so as to facilitate the glue coating of the plate, wherein the movable block is conveniently adjusted to move along the direction of the second screw rod under the threaded cooperation of the moving block and the second screw rod, and the rack is driven to move synchronously under the action of the fixed rod, and the meshing action of the rack and the gear, and the rotation cooperation of the support shaft and the fixed plate, combined with the disc, drives the clamping mechanism to rotate, and then drives the clamped plate to rotate with the support shaft as the center, until the disc drives the extrusion block to contact the pressure sensor on the lower side, completing the flipping of the plate, and facilitating the glue coating of the other side of the plate, without the need for the staff to manually flip the plate, effectively improving the processing efficiency of the plate gluing;

[0024] Under the action of the clamping member, the external plate can be pressed onto the plate coated with glue in time and pressed and fixed, which facilitates the flipping of the plate and ensures the bonding effect of the plate, so that the plates are tightly bonded together. There is no need to bond the plates after gluing on both sides, which avoids the flipping process, causing the glue to dry and harden, affecting the bonding effect of the glue, thereby ensuring the stability of the plates bonded together.

[0050] A flipping method comprises the following steps:

[0051] Step 1: First, place the plate to be coated with glue between the two clamping plates 15, and start the first motor 25. Under the action of the first screw rod 13, the two sliders 14 are driven to approach each other, and the rear end of the plate is abutted against the baffle 24 until the two clamping plates 15 are clamped on both sides of the plate, and the two sides of the plate are clamped and fixed, and then proceed to step 2;

[0052] Step 2: Apply glue to the upward side of the plate. After the glue application is completed, press the outer plate onto the plate coated with glue, and rotate the screw rod 17 on the upper side, combined with the movable block 18 and the connecting rod 19, to drive the movable plate 20 to move to the upper side of the plate. Under the elastic action of the spring 22, the extrusion plate 23 is pressed toward the plate, so that the two plates are tightly pressed together, and then proceed to step 3;

[0053] Step three: Start the second motor 27. Under the action of the second screw rod 6, combined with the moving block 10 and the fixed rod 11, the rack 9 is driven to move along the direction of the second screw rod 6. Under the meshing action of the gear 8 and the rack 9, the support shaft 3 is driven to rotate. In conjunction with the disc 4 and the clamping mechanism, the plate is driven to rotate synchronously until the extrusion block 30 contacts the pressure sensor 29 on the lower side, thereby realizing the flipping of the plate, and continuing to apply glue to the other side of the plate.

[0054] Example:

[0055] In the initial state, the moving block 10 is located at the far left, and the extruding block 30 is at the highest point driven by the disc 4. When the plate is coated with glue, the plate to be coated with glue is first placed between the two clamping plates 15, and the first motor 25 is started to drive the first screw rod 13 to rotate. Under the thread cooperation between the slider 14 and the first screw rod 13, and the thread directions of the central threaded holes of the two sliders 14 are opposite, combined with the active cooperation between the guide block and the guide groove, the two sliders 14 are driven to stably approach each other, and then the clamping plates 15 on both sides are driven to approach the direction of the plate;

[0056] When the clamping plate 15 approaches to a suitable position, the rear end of the plate is adjusted to abut against the baffles 24 on both sides, and the clamping plate 15 continues to move until it contacts the plate, and the first motor 25 is turned off. The two sides of the plate are limitedly clamped by the clamping plates 15 on both sides to ensure the stability of the plate, and then the upward side of the plate is coated with glue;

[0057] After the glue is applied to the upward side of the board, adjust the outer board to press on the board coated with glue, and glue the two boards together;

[0058] At the same time, the piston rod 21 on the upper side is pulled upward through the pull ring 26, driving the corresponding extrusion plate 23 to compress the spring 22, and adjusting the screw rod 17 on the upper side to rotate. Under the thread cooperation between the movable block 18 and the screw rod 17, and the active cooperation between the connecting rod 19 and the round hole, the movable block 18 on the upper side is adjusted to stably approach the vertical plate 16, until the movable plate 20 on the upper side is driven to move above the plate. At this time, the pull ring 26 is released, and under the elastic action of the spring 22, the extrusion plate 23 is pressed downward and pressed on the top of the plate. Under the action of glue, the two plates are tightly bonded together;

[0059] Secondly, the second motor 27 is started to drive the second screw rod 6 to rotate. Under the thread cooperation between the moving block 10 and the second screw rod 6, and the sliding cooperation between the moving block 10 and the guide rod 7, the moving block 10 is driven to move stably to the left along the direction of the second screw rod 6, and the rack 9 is driven to move synchronously in combination with the fixed rod 11;

[0060] Under the meshing action of the rack 9 and the gear 8, and the rotation cooperation of the support shaft 3 and the fixed plate 2, the disc 4 is driven to rotate around the support shaft 3, and the mounting plate 12 is driven to rotate synchronously through the rotation of the disc 4, and then the clamped plate is driven to rotate until the disc 4 rotates 180°. At this time, the rotation of the disc 4 drives the extrusion block 30 to rotate to the lowest point and contact with the pressure sensor 29 on the lower side. The pressure sensor 29 on the lower side is subjected to pressure and feeds back the pressure signal to the controller 31, turning off the second motor 27;

[0061] At this time, the clamped plate is rotated 180 degrees, so that the uncoated side of the plate is rotated to the upper side, achieving the purpose of turning the plate over, and continuing to coat the plate with glue, and repeating the above operation, and continuing to bond and press the coated plate;

[0062] When gluing multiple plates, it is only necessary to restore the pressing part to its initial state so that the upward side of the plate is completely exposed, and the above operations are continued to apply glue, bond, and press. This solves the problem that most existing glue coating machines can only apply glue to one side of the plate when gluing the plate. After one side is glued, the staff needs to remove the clamped and fixed plate, turn it over, clamp it again, and continue to glue the other side. The operation is relatively cumbersome, which increases the workload of the staff, resulting in a long time for gluing the plate, affecting the efficiency of gluing the plate. At the same time, it solves the problem that after the plate is glued, if the plate is not bonded in time, the glue will become dry and hardened, affecting the bonding effect of the plate, thereby ensuring the gluing efficiency and bonding effect of the plate.

[0063] It should be further explained that the installation method, connection method and setting method in the present invention are all common mechanical connection methods in the field and are well known and mastered by technical personnel in the field. As long as they can achieve their beneficial effects, they can be implemented. At the same time, the first motor 25, the second motor 27 and the pressure sensor 29 in the present invention are all purchased on the market, and technical personnel in the field can install, connect the wires and use them according to the requirements.
