Description

Technical Field

[0001] The invention belongs to the technical field of plywood production equipment, and in particular relates to a plywood plaster scraping and circulating board drying device. Background Art

[0002] Plywood plastering refers to applying a thin layer of plaster on the surface of plywood to repair minor damage or defects on the surface of plywood. The surface of plywood after plastering contains a certain amount of moisture, which needs to be removed by drying the board to solidify the plaster on the surface of the plywood for subsequent polishing and sanding. During the drying process, the plywood should be supported by a bracket or board rack to allow it to fully contact the air, increase the curing speed, and simultaneously avoid the plaster from sticking to each other and falling off due to the stacking of plywood.

[0003] At present, a rotatable drying rack is provided at the output end of a plywood scraper, and the plywood output by the scraper is transported to one end of the drying rack by a mechanical arm, and is transported to the other end of the drying rack by the rotation of the drying rack, and then is unloaded by the mechanical arm. By increasing the length of the drying rack, the time the plywood stays on the drying rack is increased, thereby playing the role of a drying board. However, the drying path of the existing drying rack is one-way, and the space under the drying rack is used for bracket circulation, and does not play the role of a drying board, resulting in a large increase in the volume of the drying rack when the drying time is increased. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a plywood plaster scraping and circulating board drying device, which at least partially solves the above problems.

[0005] The technical solution adopted by the present invention is as follows: the present invention proposes a plywood plaster scraping and circulating drying device, comprising a chain conveyor belt and a plurality of brackets for supporting plywood, wherein the plurality of brackets are arranged on a conveying chain of the chain conveyor belt, so that the plurality of brackets are driven by the chain conveyor belt to circulate and rotate; The bracket comprises a crossbeam and a support rod arranged at both ends of the crossbeam, the support rod comprises a fixed tube and a movable rod, a fixed clamping plate is fixed on the fixed tube, a movable clamping plate is fixed on the movable rod, the fixed clamping plate and the movable clamping plate are arranged opposite to each other, and the first end of the movable rod is slidably inserted in the fixed tube, so that the movable clamping plate can approach or move away from the fixed clamping plate to clamp or release the plywood; A clamping cylinder is provided at one end of the chain conveyor belt located in the direction of incoming materials, which is used to drive the movable rod to slide in a direction close to the fixed clamp plate, so that the movable clamp plate and the fixed clamp plate clamp the plywood. A releasing cylinder is also provided at one end of the chain conveyor belt located in the direction of incoming materials, and the telescopic end of the releasing cylinder faces below the chain conveyor belt, which is used to drive the movable rod to slide in a direction away from the fixed clamp plate, so as to release the plywood.

[0006] Furthermore, a spiral groove is provided at the first end of the movable rod, and a guide pin is provided on the fixed tube, and the guide pin is connected to the spiral groove. When the movable rod slides along the axis of the fixed tube, the guide pin slides along the spiral groove, and the movable rod can rotate and cause the movable splint to rotate at least 90°.

[0007] Furthermore, a linear groove is formed on the movable rod, and the linear groove is connected to an end of the spiral groove away from the fixed clamping plate, so that the movable clamping plate moves linearly in the initial stage of clamping or releasing the plywood.

[0008] Furthermore, a sliding sleeve is provided on the movable rod, and the sliding sleeve is configured to be able to slide along the axis of the movable rod. The movable clamp is fixed on the sliding sleeve, and a locking bolt is provided on the sliding sleeve for locking the position of the sliding sleeve.

[0009] Furthermore, a support inclined plate is provided on the sliding sleeve, and the support inclined plate is located on a side of the movable clamping plate close to the fixed clamping plate. When the movable clamping plate approaches the fixed clamping plate, the support inclined plate can lift up one end of the plywood.

[0010] Furthermore, a connecting rod is provided inside the fixed tube, the movable rod is rotatably connected to the connecting rod, an elastic hook is connected to the connecting rod, a slide groove corresponding to the elastic hook is provided on the fixed tube, the elastic hook slides in the slide groove, and a slot is also provided on the fixed tube, the slot is located at one end of the slide groove close to the fixed splint, and when the elastic hook is connected to the slot, the movable rod can be locked.

[0011] Furthermore, a push-pull rod is fixed on the elastic hook, and the clamping cylinder pulls the connecting rod and the movable rod in sequence through the push-pull rod, so that the movable clamp plate is close to the fixed clamp plate and the elastic hook is connected to the slot. The release cylinder disengages the elastic hook from the slot by pushing the push-pull rod.

[0012] Furthermore, a spring is provided at one end of the connecting rod away from the movable rod.

[0013] Furthermore, a rubber plate is provided on a corresponding side of the movable clamping plate and the fixed clamping plate.

[0014] Furthermore, the telescopic direction of the telescopic end of the clamping cylinder is parallel to the horizontal plane.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows: 1. By arranging a movable clamping plate on the bracket that can be close to or away from the fixed clamping plate, the movable clamping plate and the fixed clamping plate are used to clamp the plywood. When the bracket moves to the bottom of the chain conveyor belt (i.e., the return direction of the chain conveyor belt) and moves from the top to the bottom of the chain conveyor belt, the plywood on the bracket will not fall off, but move along with the bracket in the return direction of the chain conveyor belt. By using the return path of the chain conveyor belt, the drying time of the plywood can be increased. Accordingly, for the same drying time, the volume required by the present invention is smaller.

[0016] 2. By setting the movable splint so that when the movable splint slides in the direction away from the fixed splint, the movable splint can rotate and rotate at least 90°. At this time, the movable splint is separated from the supporting surface of the support rod and no longer limits the plywood. The plywood can slide in the direction of the movable splint and separate from the support rod, thereby achieving the effect of automatic unloading of the plywood. There is no need to set up a separate robot to unload the plywood on the bracket. BRIEF DESCRIPTION OF THE DRAWINGS

They are used to explain the present invention together with the embodiments of the present invention and do not constitute a limitation of the present invention. DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0022] like Figure 1 As shown, the present invention proposes a plywood plaster scraping and circulating drying device, a chain conveyor belt 1 and a plurality of brackets 2 arranged on the chain conveyor belt 1, the chain conveyor belt 1 drives the plurality of brackets 2 to circulate and rotate along the conveying direction of the chain conveyor belt 1, and the rotation direction is as follows: Figure 2 shown.

[0023] Among them, the chain conveyor belt 1 includes a chain, a sprocket, a driving device, a supporting guide rail and a bearing device. The sprockets are arranged at both ends of the bearing device, the supporting guide rail is located between the two sprockets, the chain is wound around the two sprockets, and the chain between the two sprockets is supported by the supporting guide rail. The driving device drives the sprocket on one side to start the chain and the sprocket to start running, and the bracket 2 installed on the chain moves with the chain.

[0024] In this way, the present invention is installed at the output end of the plywood scraper. As the chain conveyor belt 1 is driven, the brackets 2 correspond to the output end of the plywood scraper one by one in a horizontal posture, so that the plywood output by the plywood scraper can be transported to the bracket 2 by a robot or a conveyor belt, and the plywood is supported by the bracket 2. As the chain conveyor belt 1 is driven, the bracket 2 moves toward the output end of the chain conveyor belt 1. During the movement, the plywood is dried on the bracket 2 until the bracket 2 moves to the output end of the chain conveyor belt 1, and then the plywood is unloaded.

[0025] Combination Figure 3 , Figure 4 and Figure 5 As shown, the bracket 2 includes a crossbeam 3 and a supporting rod 4 arranged at both ends of the crossbeam 3, the crossbeam 3 is fixed on the chain of the chain conveyor 1, the supporting rod 4 includes a fixed tube 41 and a movable rod 42, a fixed splint 6 is fixed on the fixed tube 41, and a movable splint 5 is fixed on the movable rod 42, the fixed splint 6 and the movable splint 5 are arranged relatively to each other, the first end of the movable rod 42 is slidably inserted in the fixed tube 41, and the movable rod 42 can slide along the axis of the fixed tube 41, so that the movable splint 5 can approach or move away from the fixed splint 6, when the movable splint 5 approaches the fixed splint 6, it can clamp the plywood, and when the movable splint 5 moves away from the fixed splint 6, it can release the plywood.

[0026] In this way, after the plywood is placed on the bracket 2, the two support rods 4 support the plywood. At the same time, the movable clamping plate 5 is moved closer to the fixed clamping plate 6 by sliding the movable rod 42, and the plywood is clamped at both ends of the plywood by the movable clamping plate 5 and the fixed clamping plate 6. At this time, the plywood is clamped and fixed on the bracket 2. When the bracket 2 moves to the bottom of the chain conveyor belt 1 (i.e., the return direction of the chain conveyor belt 1) and moves from the top of the chain conveyor belt 1 to the bottom, the plywood on the bracket 2 will not fall off, and moves along the return direction of the chain conveyor belt 1 with the bracket 2. The return path of the chain conveyor belt 1 can increase the drying time of the plywood. When the bracket 2 moves to below the board placing end of the chain conveyor belt 1, the movable clamping plate 5 is moved away from the fixed clamping plate 6 by sliding the movable rod 42, releasing the plywood, so that the board placing end and the board unloading end are located on the same side, and the stroke of the chain conveyor belt 1 is fully utilized. For the same length of the chain conveyor belt 1, the present invention has a longer board drying time. Correspondingly, for the same board drying time, the present invention requires a smaller volume.

[0027] In an optional embodiment, rubber plates are provided on the corresponding side surfaces of the movable clamping plate 5 and the fixed clamping plate 6. When clamping the plywood, the rubber plates can play an anti-slip role, making the clamping of the plywood more stable.

[0028] Combination Figure 6 and Figure 7 As shown, a spiral groove 45 is provided at the first end of the movable rod 42, and a guide pin 46 is provided on the fixed tube 41. The guide pin 46 is connected to the spiral groove 45. When the movable rod 42 slides along the axis of the fixed tube 41, the guide pin 46 slides along the spiral groove 45. Under the action of the guide pin 46 and the spiral groove 45, the movable rod 42 can rotate along its own axis and cause the movable splint 5 to rotate at least 90°.

[0029] When the movable rod 42 slides in the direction away from the fixed splint 6, the movable rod 42 rotates along its own axis and causes the movable splint 5 to rotate at least 90°. At this time, the movable splint 5 is separated from the supporting surface of the support rod 4 and no longer limits the plywood. The plywood can slide away from the support rod 4 in the direction of the movable splint 5.

[0030] It should be noted that, by adjusting the size of the movable splint 5 , when the movable splint 5 is rotated 90° along the axis of the movable rod 42 , the movable splint 5 will not block the downward movement of the plywood.

[0031] In this way, when the bracket 2 moves to the bottom of the plate-laying end of the chain conveyor belt 1, the movable splint 5 is moved away from the fixed splint 6 by sliding the movable rod 42. At the same time, the movable rod 42 rotates along its own axis to rotate the movable splint 5 at least 90°. The movable splint 5 no longer limits the plywood. At this time, the plywood can slide away from the bracket 2 in the direction where the movable splint 5 is located by gravity (such as Figure 2 As shown), it plays the role of automatic unloading of the board, and there is no need to set up a separate robot to unload the plywood on the bracket 2.

[0032] Furthermore, a linear groove 451 is formed on the movable rod 42, and the linear groove 451 is connected to an end of the spiral groove 45 away from the fixed clamping plate 6; When the movable rod 42 slides toward the fixed clamping plate 6, the spiral groove 45 and the guide pin 46 can first rotate the movable rod 42, rotate the movable clamping plate 5 to be symmetrical with the fixed clamping plate 6, and then the guide pin 46 slides into the linear groove 451. At this time, the movable rod 42 no longer rotates, and the movable clamping plate 5 and the fixed clamping plate 6 clamp the plywood in a linear motion. When the movable rod 42 slides in the direction away from the fixed splint 6, the guide pin 46 and the linear groove 451 can first make the movable rod 42 move linearly, and the movable splint 5 loosens the plywood with linear motion, and then the guide pin 46 slides into the spiral groove 45, and then the movable rod 42 is rotated, thereby rotating the movable splint 5 to one side and disengaging from the supporting surface of the support rod 4. The plywood is no longer limited, and the plywood can slide in the direction of the movable splint 5 and disengage from the support rod 4.

[0033] The movable clamping plate 5 moves in a straight line in the initial stage of clamping or releasing the plywood, and when clamping the plywood, it avoids rotation to cause the plywood to loosen, thereby ensuring the stability of the clamping.

[0034] Combination Figure 2 As shown, a clamping cylinder 8 is provided at one end of the chain conveyor belt 1 in the direction of incoming materials, which is used to drive the movable rod 42 to slide in the direction close to the fixed clamp plate 6, so that the movable clamp plate 5 and the fixed clamp plate 6 clamp the plywood. A releasing cylinder 9 is also provided at one end of the chain conveyor belt 1 in the direction of incoming materials, and the telescopic end of the releasing cylinder 9 faces the bottom of the chain conveyor belt 1, and is used to drive the movable rod 42 to slide in the direction away from the fixed clamp plate 6 to release the plywood.

[0035] Furthermore, the telescopic direction of the telescopic end of the clamping cylinder 8 is parallel to the horizontal plane. When the plywood is placed on the bracket 2, the bracket 2 is in a horizontal state, so that the clamping cylinder 8 can drive the movable rod 42 after the plywood is placed on the bracket 2, so that the movable clamping plate 5 and the fixed clamping plate 6 clamp the plywood. The telescopic direction of the telescopic end of the release cylinder 9 is at an angle of 30-45° to the horizontal plane and is tilted downward. When the bracket 2 moves below the board release end of the chain conveyor belt 1, the release cylinder 9 can drive the movable rod 42 to move the movable splint 5 away from the fixed splint 6, thereby releasing the plywood.

[0036] Combination Figure 4 , Figure 5 , Figure 8 and Fig.11 As shown, a connecting rod 43 is provided inside the fixed tube 41, and the movable rod 42 is rotatably connected to the connecting rod 43, and the movable rod 42 is pulled by the connecting rod 43 to slide. At the same time, since the movable rod 42 is rotatably connected to the connecting rod 43, the sliding pulling of the connecting rod 43 will not affect the rotation of the movable rod 42; An elastic hook 7 is connected to the connecting rod 43, and a slide groove 401 corresponding to the elastic hook 7 is provided on the fixed tube 41. The elastic hook 7 slides in the slide groove 401. A slot 402 is also provided on the fixed tube 41. The slot 402 is located at one end of the slide groove 401 close to the fixed splint 6. The movable rod 42 and the connecting rod 43 move synchronously. When the connecting rod 43 pulls the movable rod 42 to move in the direction close to the fixed splint 6, the elastic hook 7 slides along the slide groove 401 until the elastic hook 7 is connected to the slot 402. At this time, the movable rod 42 is locked, so that the movable splint 5 and the fixed splint 6 can stably clamp the plywood.

[0037] In a specific embodiment, a push-pull rod 71 is fixed on the elastic hook 7, and the clamping cylinder 8 pulls the connecting rod 43 and the movable rod 42 in sequence through the push-pull rod 71, so that the movable clamp plate 5 is close to the fixed clamp plate 6, and the elastic hook 7 is connected to the clamping groove 402, and the release cylinder 9 pushes the push-pull rod 71 to disengage the elastic hook 7 from the clamping groove 402 (such as Fig. 9 , Fig.10 and Fig.11 As shown), and push the connecting rod 43 and the movable rod 42 to move the movable splint 5 away from the fixed splint 6.

[0038] Furthermore, a spring 44 is provided at one end of the connecting rod 43 away from the movable rod 42. When the connecting rod 43 pulls the movable rod 42 to move in the direction of making the movable splint 5 approach the fixed splint 6, the spring 44 is compressed and stores force. When the connecting rod 43 and the movable rod 42 are pushed away from the fixed splint 6, the spring 44 is released, elastically supporting the connecting rod 43 and the movable rod 42, so that the movable splint 5 is always in a released state, thereby preventing the movable rod 42 from sliding during the upward movement of the bracket 2, causing the movable splint 5 to approach the fixed splint 6, thereby making it impossible to clamp the plywood.

[0039] Combination Figure 4 and Figure 5 As shown, a sliding sleeve 51 is sleeved on the movable rod 42, and the sliding sleeve 51 is configured to be able to slide along the axis of the movable rod 42. The movable splint 5 is fixed on the sliding sleeve 51, and a locking bolt 52 is provided on the sliding sleeve 51 for locking the position of the sliding sleeve 51. Since the sliding distance of the movable splint 5 when clamping or releasing the plywood is fixed, the position of the movable splint 5 can be adjusted by adjusting the position of the sliding sleeve 51 on the movable rod 42 and locking it with the locking bolt 52 to adapt to the clamping of plywood of different sizes.

[0040] It should be noted that the locking bolt 52 and the movable clamping plate 5 are respectively located on two symmetrical sides of the sliding sleeve 51. When the movable rod 42 rotates 90 degrees, the locking bolt 52 will not block the unloading of the plywood.

[0041] Combination Figure 4 , Figure 5 and Figure 7As shown, a supporting inclined plate 53 is provided on the sliding sleeve 51, and the supporting inclined plate 53 is located on the side of the movable splint 5 close to the fixed splint 6. When the movable splint 5 approaches the fixed splint 6 to clamp the plywood, the supporting inclined plate 53 can lift one end of the plywood to tilt the plywood. At this time, the plywood does not contact the supporting rod 4, thereby preventing the supporting rod 4 from blocking the plywood and causing insufficient drying of the local plaster.

[0042] Working principle of the present invention: the present invention is installed at the output end of the plywood scraper. With the driving of the chain conveyor 1, the brackets 2 correspond to the output end of the plywood scraper one by one in a horizontal posture. The plywood output by the plywood scraper can be transported to the bracket 2 by a manipulator or a conveyor belt. The plywood is supported by two support rods 4. At the same time, the active rod 42 is pulled by the clamping cylinder 8 to make the active splint 5 approach the fixed splint 6. The active splint 5 and the fixed splint 6 are used to move the plywood from both ends. Clamp the plywood. At this time, the plywood is clamped and fixed on the bracket 2. With the driving of the chain conveyor 1, the plywood moves along the conveying direction of the chain conveyor 1. When the bracket 2 moves to the bottom of the chain conveyor 1 (i.e., the return direction of the chain conveyor 1), and in the process of moving from the top to the bottom of the chain conveyor 1, the plywood on the bracket 2 will not fall off, and will move along the return direction of the chain conveyor 1 with the bracket 2. By using the return path of the chain conveyor 1, the drying time of the plywood can be increased; When the bracket 2 moves to the bottom of the plate-releasing end of the chain conveyor 1, the movable rod 42 is pushed by releasing the cylinder 9 to move the movable splint 5 away from the fixed splint 6. At the same time, the movable rod 42 rotates along its own axis to rotate the movable splint 5 at least 90°. The movable splint 5 no longer limits the plywood. At this time, the plywood can slide away from the bracket 2 in the direction where the movable splint 5 is located by gravity (such as Figure 2 As shown), it plays the role of automatic unloading of the board, and there is no need to set up a separate robot to unload the plywood on the bracket 2.

[0043] In summary of the above embodiments: by arranging a movable clamping plate 5 on the bracket 2 that can be close to or away from the fixed clamping plate 6, the movable clamping plate 5 and the fixed clamping plate 6 are used to clamp the plywood at both ends of the plywood, when the bracket 2 moves to the bottom of the chain conveyor belt 1 (i.e., the return direction of the chain conveyor belt 1), and in the process of moving from the top to the bottom of the chain conveyor belt 1, the plywood on the bracket 2 will not fall off, and moves along the return direction of the chain conveyor belt 1 with the bracket 2. By using the return path of the chain conveyor belt 1, the drying time of the plywood can be increased. Accordingly, for the same drying time, the volume required by the present invention is smaller; By setting the movable splint 5 so that when the movable splint 5 slides in the direction away from the fixed splint 6, the movable splint 5 rotates and rotates at least 90°, at this time, the movable splint 5 is separated from the supporting surface of the support rod 4 and no longer limits the plywood. The plywood can slide in the direction of the movable splint 5 to separate from the support rod 4, thereby achieving the effect of automatic unloading of the plywood, and there is no need to separately set up a robot to unload the plywood on the bracket 2.
