Description

Technical Field

[0001] This utility model belongs to the field of board processing technology, and more specifically, relates to a surface treatment device for solid wood boards. Background Technology

[0002] Solid wood boards are wood panels made from whole pieces of wood (logs). During the processing of these boards, there are often situations where it is necessary to rotate the boards 180° to process the back side (such as spraying or sanding) or to perform quality inspections.

[0003] Application No.: CN202222898613.4 (Announcement No.: CN218706881U) discloses a board conveying device for wardrobe processing in whole-house customization, including a first conveyor frame body and a second conveyor frame body. A flipping mechanism is provided between the first conveyor frame body and the second conveyor frame body. The flipping mechanism includes a rotating drum. When heavier solid wood boards are conveyed on the conveyor frame, by setting up a rotating drum, a driving component, a rectangular shell and a pushing component, the heavier solid wood boards can be automatically flipped during conveying without affecting the smooth conveying of the heavier solid wood boards.

[0004] The dimensions of the plate are limited when the above-mentioned patent flips over. If the width of the plate does not match the rectangular shell, it will affect the movement and flipping of the plate, resulting in a large limitation on the size of the plate. If it is too large, it will affect the entry of the plate, and if it is too small, it will cause displacement, resulting in uneven force during the movement. Utility Model Content

[0005] In view of this, the present invention provides a surface treatment device for solid wood panels to solve the technical problem that the size of the panel is limited when flipping, and the panel width does not match the rectangular shell, which will affect the movement and flipping of the panel.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a surface treatment device for solid wood boards, which has two horizontally parallel and spaced support frames. Two longitudinally parallel and spaced conveyor bodies are fixedly installed on each support frame. The conveyor belt of the conveyor body drives the board to move at a uniform speed.

[0008] The device includes a disc that moves the sheet material from the left conveyor body to the right conveyor body and flips it over; the disc has two grooves.

[0009] The technical advantages of the surface treatment device for solid wood panels provided by this utility model are as follows:

[0010] Based on the above technical solution, the surface treatment device for solid wood panels of this utility model can be further improved as follows:

[0011] Furthermore, a rotating shaft is provided between the two support frames for rotatable connection, and two discs located at the front and rear ends of the conveyor body are fixedly installed on the circumferential surface of the rotating shaft;

[0012] The two grooves are located on the same central axis, penetrate the circumferential surface of the disk, and are symmetrically distributed on both sides of the rotating shaft.

[0013] Furthermore, multiple horizontally distributed upright plates are fixedly installed on the support frame. The front and rear walls at the upper end of the upright plates are provided with bosses and are fixedly connected to the frame of the conveyor body on the same side.

[0014] Furthermore, a support plate is installed on the left wall of the leftmost upright plate, and the support plate has symmetrically arranged movable grooves, each of which is slidably connected to a T-shaped rod.

[0015] A cylindrical rod is fixedly installed on the top wall of each T-shaped rod, and a roller is rotatably connected to the outer circumference of the cylindrical rod through a bearing.

[0016] Furthermore, two symmetrically arranged cylinders are fixedly installed on the bottom wall of the support plate. The moving ends of the cylinders are far apart from each other, and the T-shaped rods are fixedly installed on the ends of the cylinders. The T-shaped rods are located on the front and rear sides of the conveyor body.

[0017] Compared with the prior art, the beneficial effects of the surface treatment device for solid wood panels provided by this utility model are:

[0018] The upright plate has protrusions on the front and rear sides of its top surface, which connect to the conveyor frame without affecting the movement of the conveyor belt; the upright plate is used to raise the conveyor body, so that there is a certain height between the support frame and the conveyor body.

[0019] By setting two sets of rollers at the front and rear, the board is guided and kept in the middle to avoid displacement and the risk of falling during movement and flipping.

[0020] By setting chutes on the front and rear sides of the conveyor body, even if the diameter of the chutes is large, it will not affect the overall length, thus reducing the floor space required. Attached Figure Description

[0033] Example 1

[0034] like Figure 1-4 As shown, this utility model provides a surface treatment device for solid wood boards, which has two horizontally parallel and spaced support frames 1, and two vertically parallel and spaced conveyor bodies 11 are fixedly installed on each support frame 1. The conveyor belt of the conveyor body 11 drives the board to move at a uniform speed.

[0035] Among them, there is a disc 22 that moves the plate from the left conveyor body 11 to the right conveyor body 11 and flips it over, and the disc 22 is provided with two sliding grooves 23.

[0036] Optionally, in the above technical solution, a rotating shaft 21 is provided between the two support frames 1 for rotatable connection, and two discs 22 located at the front and rear ends of the conveyor body 11 are fixedly installed on the circumferential surface of the rotating shaft 21.

[0037] The two grooves 23 are located on the same central axis, pass through the circumference of the disk 22, and are symmetrically distributed on both sides of the rotating shaft 21.

[0038] Optionally, in the above technical solution, multiple horizontally distributed upright plates 12 are fixedly installed on the support frame 1. The front and rear walls of the upper end of the upright plate 12 are provided with bosses and are fixedly connected to the frame of the conveyor body 11 on the same side.

[0039] Optionally, in the above technical solution, a support plate 41 is installed on the left wall of the leftmost upright plate 12. The support plate 41 has symmetrically arranged moving grooves 40, and a T-shaped rod 43 is slidably connected in each moving groove 40.

[0040] Cylindrical rods 44 are fixedly installed on the top wall of each T-shaped rod 43, and rollers 45 are rotatably connected to the outer circumference of the cylindrical rods 44 through bearings.

[0041] Optionally, in the above technical solution, two symmetrically arranged cylinders 42 are fixedly installed on the bottom wall of the support plate 41. The movable ends of the cylinders 42 are far apart from each other, and T-shaped rods 43 are fixedly installed on the ends of each cylinder. The T-shaped rods 43 are located on the front and rear sides of the conveyor body 11.

[0042] Specifically, the width of the board material adapted to this device is greater than the longest longitudinal distance between the two discs 22, that is, greater than the width between the two longitudinally arranged conveyor bodies 11, and less than the maximum distance between the two T-shaped bars 43; the maximum length of the board material adapted to this device is not more than half the length of the chute 23; the thickness of the board material adapted to this device is not more than the height between the top surface of the chute 23 and the top surface of the conveyor belt of the conveyor body 11; preferably, the weight of the solid wood board material adapted to this device does not exceed 50Kg.

[0043] Furthermore, a motor mount B32 is fixedly installed on the rear wall of the rear side plate 31, and a motor B33 is fixedly installed on the motor mount B32. The output shaft of the motor B33 extends forward and is connected to the rotating shaft 21.

[0044] Furthermore, each of the two conveyor bodies 11 on each support frame 1 is fixedly connected to a rotating shaft 13 near the end of the rotating shaft 21. A pulley A14 is fixedly installed in the middle of the rotating shaft 13. A motor A16 is located below the pulley A14. The output shaft of the motor A16 extends rearward and a pulley B17 is installed at its end. A belt 18 is connected to both the pulley A14 and the pulley B17. A motor base 15 is fixedly installed on the side of the upright plate 12 near the rotating shaft 21, and the motor A16 is fixedly installed on the front wall of the motor base 15. The rear wall of the frame of the front conveyor body 11 is fixedly installed on the front wall of the upright plate 12, and the front wall of the frame of the rear conveyor body 11 is fixedly installed on the rear wall of the upright plate 12. The motor A16 is a geared motor.

[0045] When the chute 23 is in a horizontal state, the bottom surface of the chute 23 is lower than the top surface of the conveyor belt of the conveyor body 11. The right chute 23 and the left chute 23 are centrally symmetrically arranged. The horizontal axis center line of the chute 23 is aligned with the top surface of the conveyor belt of the conveyor body 11 and the midpoint of the rotating shaft 21.

[0046] Among them, cylinder 42 is a cylinder with a guide rod. The two conveyor bodies 11 on each support frame 1 are longitudinally symmetrically distributed, and the two cylinders 42 are also longitudinally symmetrically distributed. During operation, the piston rods (moving ends) of the two cylinders 42 extend and retract synchronously, and the extension and retraction lengths are always consistent. This can be achieved using existing cylinders, controllers, and control elements. Preferably, the process is: "air compressor → triplet → flow divider valve → solenoid valve (three-way valve or two-position five-way valve) → throttle valve → cylinder".

[0047] The standard air circuit.

[0048] The top wall of roller 45 is higher than the top surface of the conveyor belt of conveyor body 11.

[0049] Furthermore, two semi-circular grooves 24 can be opened to reduce weight, and rubber strips can be fixedly installed on the inner wall of the slide groove 23 (the inner wall opposite to the circumferential surface).

[0050] Furthermore, a sensor 3 is fixedly installed on the right wall of the rightmost upright plate 12 on the left support frame 1. A diffuse reflection photoelectric sensor (single head, integrating transmission and reception) is preferred. When blocked, it outputs an electrical signal, which is transmitted to the controller (such as PLC) to trigger the motor B33 to rotate. The sensor 3 is located directly below the right wall of the left slide 23 (in the horizontal state of the slide 23), within 10mm to the left.

[0051] The output shaft of motor B33 drives shaft 21 to rotate 180 degrees and then stops. Required components include: Actuation end: a stepper motor (or servo motor) with an encoder + matching driver (such as an A4988 stepper driver); Detection end: a diffuse reflection photoelectric sensor (NPN type); Control end: Arduino (or PLC); Braking end: an electromagnetic brake (optional, a motor with a built-in brake can be used to lock the motor shaft to prevent inertia when stopping); Power supply: 24V DC power supply (powering the sensor), 12V DC power supply (powering the motor driver), 5V power supply (powering the Arduino); In other words, when the sensor is not obstructed, the motor is in standby mode (the brake is engaged).

[0052] When the sensor is blocked (detecting a low level), the motor starts rotating and simultaneously begins counting encoder pulses (or stepper motor pulses). When the pulse count reaches the "180-degree corresponding value," pulse transmission immediately stops, triggering the brake to lock. Motor B33 has a gearbox and can utilize an existing integrated "stepper motor + gearbox" product.

[0053] Alternatively, staff can observe that when the right wall of the plate is pressed against the right wall of the left slide 23, motor B33 is started; when the plate is pressed against the top surface of the conveyor belt of the right end conveyor body 11, motor B33 is turned off.

[0054] Working principle: In the initial state, the top wall and bottom wall of the chute 23 are located on the upper and lower sides of the top surface of the conveyor belt of the conveyor body 11, and the distance between the top wall of the chute 23 and the top surface of the output belt is sufficient for the appropriate plate to enter.

[0055] 1. Start the two motors A16 to drive the conveyor belts of the corresponding two conveyor bodies 11 to move at a constant speed. Adjust the distance between the two T-shaped rods 43 (adjusted by the simultaneous extension and retraction of the piston rods of the two cylinders 42) so that the distance between the two T-shaped rods 43 is greater than the width of the board by 0-4mm. Place the board that needs to be flipped on the two conveyor bodies 11 of the left end support frame 1 and at the T-shaped rods 43. Then both the front and rear ends of the board will exceed the disc 22.

[0056] 2. First, place the board on the two conveyor bodies 11 of the left end support frame 1. Then, move the two T-shaped rods 43 inward synchronously so that the rollers 45 clamp the board in the middle. Then, start the motor A16 to make the conveyor bodies 11 transport the board.

[0057] The roller 45 clamps the plate in the middle, which can prevent the plate from tilting and falling due to unbalanced force on one side when flipping.

[0058] When the plate moves into the chute 23, the sensor 3 is blocked by the plate and sends a signal. The motor B33 starts and drives the rotating shaft 21 to rotate, so that the plate on the disc 22 rotates accordingly. The rotation stroke is 180 degrees, and the plate moves from the left conveyor body 11 to the right conveyor body 11. The plate is flipped over, that is, the bottom surface on the left conveyor body 11 is the top surface on the right side.

[0059] When the plate moves onto the right conveyor body 11, motor B33 stops, and the plate moves to the next process under the action of the conveyor belt.

[0060] This device is used for the flipping process in the surface processing of sheet materials (such as painting). Before flipping, one side is treated, and after flipping, the other side is treated. It should be noted that when using painting, a drying device for painting is required at the same time. The sheet material needs to be dried while moving on the conveyor body 11. Existing equipment can be used for the painting device for surface treatment.

[0061] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
