Description

Technical Field

[0001] The invention relates to the technical field of board drying, in particular to furniture board drying equipment. Background Art

[0002] The boards used to make furniture need to be dried after painting to remove moisture from the paint film. Some research on board drying equipment has been done in the prior art. For example, a board drying rack disclosed in the Chinese utility model patent with publication number CN219797728U includes a drying seat, an auxiliary wind mechanism is provided on one side of the drying seat, a pair of second supporting slide grooves are provided on the upper side wall of the drying seat, a pair of supporting sliders are slidably inserted on the pair of second supporting slide grooves, and drying board grooves are provided on the two pairs of supporting sliders respectively, and a rotating supporting mechanism is provided in the drying board grooves. For another example, a Chinese utility model patent with publication number CN210740917U discloses a new type of plate drying rack, including a drying rack, a fan and a solar panel, the drying rack including two parallel frames one and two, frame one including a front vertical axis one, a rear vertical axis one and a crossbeam one connecting the front and rear vertical axis one, frame two including a front vertical axis two, a rear vertical axis two and a crossbeam two connecting the front and rear vertical axis two, the fan rack is installed at the front end of the drying rack and is hinged to the front vertical axis one and the rear vertical axis one through a connecting piece, a solar panel is installed on the top of the fan rack, the solar panel is connected to a battery, the battery is connected to a drive motor, and the drive motor is connected to the fan, wherein the fan and the battery are installed in the fan rack.

[0003] In the actual processing process, many decorative boards are curved boards. When the curved boards are dried by the existing drying equipment, there are two drying methods. One is to face the bulge of the curved board upwards and support the inner curved surface of the curved board by the cross bar on the drying equipment. However, the center of gravity of the curved board in this method is relatively high, and it is easy to fall off the cross bar when subjected to external force; the other method is to face the bulge of the curved board downwards and support the outer curved surface of the curved board by the cross bar on the drying equipment. In this method, the center of gravity of the curved board is relatively low, and it is not easy to fall off the cross bar when subjected to external force; however, since the middle position of the curved board is concave downward, and the paint film on the surface of the board has not yet solidified in the initial stage of drying and has a certain fluidity, the paint at the higher positions on both sides of the upper surface of the curved board will slowly gather to the lower middle position, resulting in the paint film thickness in the middle position of the upper surface being greater than the paint film thickness at the two sides; especially for some curved boards with thicker paint films, this phenomenon is more serious.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Embodiment 1

[0028] like Figure 1 and Figure 5As shown, the present embodiment provides a furniture board drying device, comprising a base 1, on which a vertical portal frame 2 is fixedly mounted, and a guide rail 3 parallel to the crossbeam of the portal frame 2 is also fixedly mounted on the base 1; three first vertical rods 4 arranged along the guide rail 3 are fixedly mounted on the guide rail 3, and the middle first vertical rod 4 corresponds to the middle position of the guide rail 3; a second vertical rod 5 is mounted on the guide rail 3 between two adjacent first vertical rods 4, that is, there are two second vertical rods 5 in total; a plurality of round rods 6 evenly arranged from top to bottom are mounted on both the first vertical rod 4 and the second vertical rod 5, and the round rods 6 are perpendicular to the plane where the portal frame 2 is located; the bottom end of the second vertical rod 5 is slidably matched with the guide rail 3, and the furniture board drying device in the present embodiment also includes a positioning assembly for positioning the horizontal position of the second vertical rod 5; a plurality of strip-shaped protrusions 601 are evenly arranged on the surface of the round rod 6 on the second vertical rod 5 along its circumference; a hydrophobic coating is sprayed on the surface of the round rod 6 to avoid sticking of paint.

[0029] Specifically, the furniture board drying equipment in the present embodiment is placed in a ventilated drying room, and the drying room is also equipped with fans, filter dust collectors and other equipment, which are prior arts in this field and will not be elaborated in detail here; in the present embodiment, the number of round rods 6 on each first vertical rod 4 and the second vertical rod 5 is the same, and the round rods 6 on the same layer are horizontally flush; when drying the flat board, the operator only needs to place the flat board horizontally on the round rods 6 on the same layer, and support the lower surface of the flat board by the round rods 6 to keep the flat board in a stable state; for flat boards of different lengths, the operator needs to adjust the horizontal position of the second vertical rods 5; for shorter flat boards, the operator needs to translate the two second vertical rods 5 to the middle of the guide rail 3, that is, to translate the two second vertical rods 5 toward each other; for longer flat boards, the operator needs to translate the two second vertical rods 5 to both sides of the guide rail 3, that is, to translate the two second vertical rods 5 in opposite directions.

[0030] For the curved plate, the operator needs to place the inner curved surface of the curved plate upward, and then tilt the curved plate so that one side of the curved plate is high and the other side is low, and then adjust the horizontal position of one of the second vertical rods 5, and support the upper surface of the curved plate through the round rod 6 on the second vertical rod 5, and then adjust the horizontal position of another second vertical rod 5, and support the bottom edge of the lower end of the curved plate through the round rod 6 on the second vertical rod 5 (such as Figure 5As shown); It should be noted that after the operator adjusts the horizontal position of the second vertical rod 5, the positioning assembly positions the horizontal position of the second vertical rod 5, and the second vertical rod 5 will not move in the opposite direction under the action of external force. Even if the mass of the curved plate is large, it will not push the second vertical rod 5 to move, thereby ensuring the stability of the curved plate during drying; the reason why the curved plate can maintain a stable state is that the center of gravity of the curved plate in the inclined state is biased toward its lower end, so the curved plate has a tendency to fall toward its lower side, but due to the strip protrusion 601 (specifically Figure 5 The leftmost strip protrusion 601 in the figure supports the bottom edge of the lower end of the arc-shaped plate, so the lower side of the arc-shaped plate will not fall; in addition, the strip protrusion 601 on the round rod 6 (specifically Figure 5 The uppermost strip protrusion 601 also blocks the lower end of the arc-shaped plate, thereby preventing the arc-shaped plate from sliding to a state where both ends are flush under the action of gravity.

[0031] In summary, in the first stage of drying, the curved plate maintains Figure 3 In the inclined state shown in the figure, the paint covering it will gather at the lower part of the curved plate; after drying for a period of time, the operator adjusts the horizontal position of the two second vertical rods 5 and adjusts the state of each curved plate so that the heights of the two ends of the curved plate are reversed, that is, the curved plate becomes Figure 3 The mirror image state, drying enters the second stage; then, the paint that originally gathered on the curved plate in the first stage will flow back in the opposite direction, thereby reducing the occurrence of paint gathering; it should be noted that Figure 3 In this state, the paint near the right end of the curved plate has a relatively gentle curvature, and its gravity will not cause it to gather significantly at the lower part of the curved plate. This part of the paint has a better drying effect in the first stage, and there will be no obvious gathering phenomenon in the second stage. The paint near the left end of the curved plate will gather significantly at the lower part of the curved plate in the first stage, and the drying effect will be poor. In the second stage, there will be a more obvious reflux phenomenon, thereby ensuring that the overall paint thickness of the curved plate is uniform.

[0032] like Figure 4As shown, the positioning assembly includes a positioning plate 701 fixedly installed inside the base 1 and corresponding to the range of horizontal displacement of the second vertical rod 5, and a plurality of positioning grooves 702 are evenly opened on the positioning plate 701 in the horizontal direction; a horizontal shaft 703 is rotatably installed on the second vertical rod 5 corresponding to the position of the positioning plate 701, and a rotating arm 704 is fixedly sleeved on the horizontal shaft 703, and a positioning block 705 matching the positioning groove 702 is installed on the rotating arm 704; the positioning block 705 is cylindrical and parallel to the horizontal shaft 703, the positioning block 705 is located at one end of the rotating arm 704, and the horizontal shaft 703 is located at the other end of the rotating arm 704; the bottom of the positioning groove 702 is semicircular and adapted to the positioning block 705, the side of the positioning groove 702 facing the middle of the guide rail 3 is an arc surface, and the other side of the positioning groove 702 is a vertical surface; a notch and a groove 705 are opened on the rotating arm 704 06, a metal spring piece 707 is fixedly inserted on the second vertical rod 5, and one end of the metal spring piece 707 forms a hook portion 7071; the metal spring piece 707 has a working state, and in the working state, the hook portion 7071 is inserted into the groove 706, so that the positioning block 705 is in a state of separation from the positioning groove 702 when there is no external force; a first guiding inclined surface 708 is provided on the positioning plate 701 at a position corresponding to the top of the arc-shaped surface of the positioning groove 702 closest to the middle of the guide rail 3, and a horizontal groove 709 is provided on the positioning plate 701, and the horizontal groove 709 is connected to the positioning groove 702 farthest from the middle of the guide rail 3; a second guiding inclined surface 710 is provided on the positioning plate 701 at a position corresponding to the top of the horizontal groove 709; both the first guiding inclined surface 708 and the second guiding inclined surface 710 are higher on the side close to the middle of the guide rail 3 and lower on the side away from the middle of the guide rail 3.

[0033] Specifically, in the initial state, the positioning block 705 is located in one of the positioning grooves 702, and the arc-shaped plate applies an oblique downward pressure on the round rod 6, so that the second vertical rod 5 is subjected to a force acting to the right. Since the right side of the positioning groove 702 is a vertical surface, the positioning block 705 is restricted and cannot move to the right, that is, the rotating arm 704, the horizontal axis 703 and the second vertical rod 5 will not move to the right, thereby positioning the second vertical rod 5 and ensuring the stability of the arc-shaped plate during the first stage of drying; in the second stage, the horizontal position of the second vertical rod 5 needs to be adjusted. The operator first pushes the second vertical rod 5 to move to the left, that is, the second vertical rod 5 moves to the middle position of the guide rail 3, and the water The horizontal shaft 703 and the rotating arm 704 move to the left synchronously, and the positioning block 705 passes through each positioning groove 702 in turn along the edge of the positioning groove 702, and the positioning block 705 swings continuously, and the amplitude of each swing of the positioning block 705 is the same, until the positioning block 705 is separated from the leftmost positioning groove 702 and fits with the first guide inclined surface 708; during the process of the positioning block 705 rising along the first guide inclined surface 708, the upward swing amplitude of the rotating arm 704 is greater than the previous upward swing amplitude, and at the same time, the edge of the rotating arm 704 fits with the curved hook portion 7071 on the metal spring piece 707, causing the metal spring piece 707 to bend and deform upward, until the rotating arm 704 swings until the curved hook portion 7071 reaches the groove When the second vertical rod 5 is moved to the right, the horizontal axis 703, the rotating arm 704 and the positioning block 705 are moved to the right synchronously, and the positioning block 705 is not in contact with the positioning groove 702. Finally, the positioning block 705 is in contact with the second guide inclined surface 710. As the operator continues to move the second vertical rod 5 to the right, the second vertical rod 5 is moved to the right. The two guiding inclined surfaces 710 exert an oblique downward force on the positioning block 705, so that the horizontal axis 703, the rotating arm 704 and the positioning block 705 overcome the limitation of the hook portion 7071 and swing downward, the hook portion 7071 disengages from the groove 706, and the metal spring piece 707 is able to recover under its own force, and the horizontal axis 703, the rotating arm 704 and the positioning block 705 are no longer restricted by the metal spring piece 707; at this time, the operator can pull the second vertical rod 5 to the left to adjust the horizontal position of the second vertical rod 5 until the positioning block 705 enters the predetermined positioning groove 702; for the second vertical rod 5 on the other side, the above steps are also installed to adjust it to the predetermined horizontal position.

[0034] It should be noted that in this embodiment, the bottom end of the hook portion 7071 is semicircular, and the gravity of the rotating arm 704 and the positioning block 705 is not sufficient to overcome the limitation of the rotating arm 704 by the hook portion 7071 and make the rotating arm 704 swing downward. However, the force applied to the positioning block 705 by the second guide slope 710 can make the rotating arm 704 overcome the limitation of the rotating arm 704 by the hook portion 7071 and swing downward.

[0035] In summary, in this embodiment, when the operator needs to adjust the horizontal position of the second vertical rod 5, there are two situations. In the first situation, the target position is located on the side close to the middle of the guide rail 3, and the operator directly pulls the second vertical rod 5 toward the middle of the guide rail 3 until the second vertical rod 5 reaches the predetermined position; in the second situation, the target position is located on the side away from the middle of the guide rail 3, and the operator needs to first pull the second vertical rod 5 toward the middle of the guide rail 3 to one end of the second vertical rod 5 stroke (the end close to the middle of the guide rail 3), and then push the second vertical rod 5 back to the other end of its stroke (the end away from the middle of the guide rail 3), and then pull the second vertical rod 5 toward the middle of the guide rail 3 until the second vertical rod 5 reaches the predetermined position. In this embodiment, the position adjustment operation of the second vertical rod 5 is simple, and it can support flat plates of different lengths and curved plates of different lengths and curvatures.

[0036] like Figure 3 As shown, the second vertical rod 5 includes a guide section 501 that slides with the guide rail 3, and a lifting section 502 that vertically slides with the guide section 501. A telescopic spring is connected between the guide section 501 and the lifting section 502. The round rod 6 on the second vertical rod 5 rotates with it. Specifically, Figure 3 When the two ends of the arc-shaped plate need to be swapped in this state, as shown by the arrow in the figure, the lifting section 502 is first pressed down to make the lifting section 502 drop a certain distance, the telescopic spring is compressed, and the corresponding round rods 6 drop a certain distance synchronously. During this process, the lower end of the arc-shaped plate will fall until the lower surface (outer arc surface) of the arc-shaped plate fits with the round rod 6; the operator then releases the lifting section 502, and the lifting section 502 will rise and reset under the action of the telescopic spring. In this way, the round rods 6 on the two second vertical rods 5 both support the lower surface of the arc-shaped plate, and the arc-shaped plate will slide to a state where the heights on both sides are the same under the action of its own gravity, that is, the arc-shaped plate will automatically return to a balanced state, so that the operator can adjust the state of each arc-shaped plate in turn.

[0037] like Figure 2 and Figure 6As shown, a gear 711 is fixedly sleeved on the round rod 6 on the second vertical rod 5, and a rack 712 meshing with the corresponding gears 711 is vertically slidably installed in the second vertical rod 5, and a claw 713 cooperating with the rack 712 is installed on the top of the lifting section 502, and an elastic member is connected between the lifting section 502 and the claw 713, and the claw 713 is used to limit the rack 712; the operator pushes the claw 713 to separate the claw 713 from the rack 712, and then Push the rack 712 up and down so that the gears 711 and the round rod 6 rotate synchronously, thereby fine-tuning the position of the strip protrusion 601 on the round rod 6 to ensure that the strip protrusion 601 can both support the bottom edge of the lower end of the arc-shaped plate and block the lower end of the arc-shaped plate; after the adjustment is completed, the operator releases the claw 713, and the claw 713 fits with the rack 712 under the action of the elastic member, and limits the rack 712.

[0038] It should also be noted that, compared with other technical means in the prior art, this embodiment does not require the additional provision of components for clamping the plate, so as to ensure the stable state of the curved plate during the drying process. Since there is no clamping component, the contact area with the curved plate is very small, and the paint film on the surface of the curved plate will not be scratched.

[0039] Embodiment 2

[0040] During actual operation, the operator needs to push the furniture board drying equipment from the end of the production line to the drying room. Since boards are placed on the furniture board drying equipment and the equipment does not have components for clamping the boards, it can only be pushed slowly to prevent the boards from falling. In the prior art, only rollers are installed on the furniture board drying equipment. The furniture board drying equipment is difficult to operate when turning, and precise turning cannot be performed. The furniture board drying equipment is prone to collision with foreign objects.

[0041] Based on the above problems, on the basis of the previous embodiment, the furniture board drying equipment in this embodiment also includes a walking mechanism, such as Figure 7As shown in the figure, in this embodiment, the base 1 is a rectangular frame structure. The traveling mechanism includes four first connecting rods 801 rotatably installed at the bottom of the base 1. The four first connecting rods 801 are respectively arranged at the corner positions of the base 1, and the rotating shafts of the first connecting rods 801 are in a vertical state. The first connecting rod 801 is L-shaped, and a traveling wheel 802 is rotatably installed at one end of the first connecting rod 801. A second connecting rod 803 is rotatably installed at the other end of the first connecting rod 801. Two T-shaped rotating frames 804 are arranged front and back on the base 1. The two ends of one rotating frame 804 are hinged to the ends of the second connecting rods 803 corresponding to the two front traveling wheels 802. The two ends of the other rotating frame 804 are hinged to the ends of the second connecting rods 803 corresponding to the two rear traveling wheels 802. A first ball seat 805 is fixedly connected to each rotating frame 804, and a push-pull rod 806 is movably installed on each first ball seat 805 through a ball hinge. A U-shaped frame 807 with an opening facing downwards is rotatably installed in the middle of the base 1. The rotation axis of the U-shaped frame 807 ( Figure 7 the dotted line in the figure) is a horizontal line and is arranged in the left-right direction. Second ball seats 808 are fixedly installed at both ends of the U-shaped frame 807. One end of the push-pull rod 806 is movably connected to the corresponding second ball seat 808 through a ball hinge. An adjustment handle 809 is fixedly installed on one of the rotating frames 804.

[0042] It should be noted that when all four traveling wheels 802 are in the forward direction, that is, when the rotation axes of all four traveling wheels 802 are Figure 7 the vertical lines in the figure (i.e., the actual left-right direction line), all four second connecting rods 803 are Figure 7 in a vertical state (i.e., the actual left-right direction arrangement state); part of the rotating frame 804 is Figure 7 in a vertical state (actually arranged in the left-right direction), and the other part is Figure 7 in a horizontal state (actually arranged in the front-back direction). Both push-pull rods 806 are Figure 7 in a horizontal state (actually arranged in the front-back direction); for the rotating frame 804 and the first connecting rod 801 on the same side (divided by front and back), the rotation axes are arranged along Figure 7 the vertical direction in the figure (the actual left-right direction arrangement).

[0043] Specifically, when steering is required, the operator only needs to turn the adjusting handle 809. When the adjusting handle 809 is turned, it will drive the rotating frame 804 connected thereto to rotate. For example: the operator turns the adjusting handle 809 clockwise, and the adjusting handle 809 drives the rotating frame 804 on the right to rotate clockwise synchronously, and the rotating frame 804 drives the first ball seat 805 connected thereto to rotate clockwise, so that the push-pull rod 806 on the right moves to the right; at the same time, when the rotating frame 804 on the right rotates clockwise, it drives the two second connecting rods 803 connected thereto to move, and the second connecting rod 803 drives the corresponding first connecting rod 801 to rotate clockwise, that is, the two walking wheels 802 on the right turn clockwise to a certain angle; when the push-pull rod 806 on the right moves to the right, it pulls the connected The second ball seat 808 and the profile frame 807 rotate to the right, and the push-pull rod 806 on the left also moves to the right under the action of the corresponding second ball seat 808. The push-pull rod 806 on the left pulls the corresponding first ball seat 805, causing the rotating frame 804 on the left to rotate counterclockwise, and the first connecting rod 801 on the left also drives the walking wheel 802 on the left to turn counterclockwise to a certain angle; assuming that the two walking wheels 802 on the left are front wheels and the two walking wheels 802 on the right are rear wheels, then when the operator turns the adjusting handle 809, the steering of the two front wheels is opposite to that of the two rear wheels. Therefore, the entire furniture board drying equipment can be turned more flexibly, and the operator can accurately control the direction of travel of the furniture board drying equipment by controlling the adjusting handle 809 to avoid collision between the furniture board drying equipment and foreign objects.
