Description

Technical Field

[0001] The invention relates to the technical field of conveying devices, and in particular to a conveying turning device and a turning method for processing composite flooring. Background Art

[0002] In the production process of composite flooring, the boards of the flooring need to be turned over so as to process the reverse side of the boards. In this process, a turning conveyor device is used to turn the boards over. Chinese patent CN206384516U discloses a plate flipping mechanism of a plate conveyor line, which clamps the plate through the gap between each two brackets. As the rotating shaft rotates, the plate clamped in the gap is flipped onto the conveyor line. The plate flipping mechanism has fewer moving components, which reduces maintenance costs. However, the bracket position of the mechanism is fixed. When the size of the plate to be flipped is too large or too small, the bracket of the flipping mechanism cannot effectively clamp the plate, causing the clamped plate to fall off from the gap or fail to clamp the plate during the flipping process, thereby affecting the flipping of the plate. The size of the gap between the two brackets is fixed, so that the bracket cannot clamp a plate that is too thick. When facing a plate that is too thin, the plate will swing in the gap during the flipping process, thereby offsetting, resulting in an inaccurate position of the flipped plate on the conveyor line, and it is easy to fall off the conveyor line.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1; See also Figure 1-Figure 8 A conveying and flipping device and a flipping method for composite floor processing, comprising a fixed frame 1 and a feed conveyor belt 11 and a discharge conveyor belt 12 respectively installed on both sides of the fixed frame 1, the fixed frame 1 is provided with a flipping mechanism 2, a locking component 5, a transmission component 6 and a pushing component 7, the flipping mechanism 2 comprises a flipping shaft 21, an adjusting component 3 and a clamping component 4, the flipping shaft 21 is rotatably arranged on the fixed frame 1, the clamping component 4 is connected with the adjusting component 3, the adjusting component 3 is installed on the flipping shaft 21, the adjusting component 3 can drive the clamping component 4 to move on the flipping shaft 21, so as to adjust the position of the clamping component 4 on the flipping shaft 21, the clamping component 4 is used to clamp the plate conveyed by the feed conveyor belt 11, and the flipping shaft 21 can drive the clamping component 4 to move on the flipping shaft 21. The component 4 rotates toward the discharge conveyor belt 12 to flip the plate on the clamping component 4 onto the discharge conveyor belt 12. The locking component 5 includes a locking plate 51, which is arranged on one side of the fixed frame 1. The locking plate 51 can move toward the flip axis 21 to lock the flip axis 21. The pushing component 7 includes a pushing plate 71, which is installed on the fixed frame 1 and is located between the flip axis 21 and the discharge conveyor belt 12. A baffle 711 is fixed on one end of the pushing plate 71 facing the flip axis 21. The transmission component 6 is fitted between the flip axis 21 and the pushing plate 71. When the flip axis 21 rotates, it can drive the transmission component 6, so that the transmission component 6 drives the pushing plate 71 to reciprocate between the flip axis 21 and the discharge conveyor belt 12.

[0020] Among them, when in use, first the feed conveyor belt 11 conveys the plate to be turned over toward the turning mechanism 2. When the plate is sent to the turning mechanism 2 by the feed conveyor belt 11, the clamping assembly 4 on the turning shaft 21 corresponds to the plate. As the feed conveyor belt 11 continues to convey, the plate will enter the clamping assembly 4. After the plate enters the clamping assembly 4, the turning shaft 21 drives the clamping assembly 4 to rotate toward the discharge conveyor belt 12 to turn over the clamped plate. At this time, there is a certain gap between the plate and the turning shaft 21. During the rotation of the turning shaft 21, the transmission assembly 6 drives the pusher under the drive of the turning shaft 21. The plate 71 moves back and forth between the flip shaft 21 and the discharge conveyor belt 12. Every time the flip shaft 21 rotates 90 degrees, the transmission component 6 will drive the push plate to complete a back and forth movement between the flip shaft 21 and the discharge conveyor belt 12. The push plate 71 is initially located next to the side wall of the fixed frame 1, close to the discharge conveyor belt 12. As the flip shaft 21 rotates, the push plate 71 moves toward the flip shaft 21. When the push plate 71 reaches the side of the flip shaft 21, the plate on the clamping component 4 rotates to the top of the push plate 71. At this time, the baffle 711 on the push plate 71 is inserted between the plate and the flip shaft 21. As the turning shaft 21 continues to turn, the push plate 71 begins to move toward the discharge conveyor belt 12. During the movement, the push plate 71 drives the plate to move in the same direction through the baffle plate 711, so that the plate extends from the clamping assembly 4 to a corresponding length. When the turning shaft 21 turns the plate over to the top of the discharge conveyor belt 12, the push plate 71 moves back to the initial position, so that the portion of the plate extending from the clamping assembly 4 can fully contact the discharge conveyor belt 12, so that the discharge conveyor belt 12 drives the plate to move, and the remaining portion of the plate is brought out of the clamping assembly 4 in time, and the turned plate is conveyed to the next process The turning shaft 21 continues to rotate and then turns the next plate onto the discharge conveyor 12. When it is necessary to turn over plates of other sizes, before turning on the device, the locking plate 51 is pushed close to the turning shaft 21 so that the locking plate 51 fixes the turning shaft 21, and then the clamping component 4 of the turning shaft 21 is driven to move by the adjusting component 3, thereby adjusting the position of the clamping component 4 on the turning shaft 21 so that the adjusted clamping component 4 matches the plate of the new size and can effectively clamp the plate of the new size, thereby ensuring that the device can turn over plates of various sizes and improving the applicability of the device.

[0021] The difference from the above embodiment is that the flipping mechanism 2 also includes a driving motor 22, which is fixedly mounted on the fixed frame 1 on the same side as the transmission assembly 6, and the end of the flipping shaft 21 close to the transmission assembly 6 is coaxially fixedly connected to the output shaft of the driving motor 22, and the driving motor 22 can drive the flipping shaft 21 to rotate on the fixed frame 1. A locking groove 211 is provided on the end of the flipping shaft 21 away from the transmission assembly 6, and the locking groove 211 corresponds to the bottom of the locking plate 51. An adjusting groove 212 is provided in the flipping shaft 21, and four notches are evenly provided on the flipping shaft 21 to communicate with the adjusting groove 212, forming a cross shape on the flipping shaft 21.

[0022] When flipping the plate, the driving motor 22 drives the flip shaft 21 to rotate toward the discharge conveyor belt 12, thereby driving the clamping assembly 4 on the flip shaft 21 to flip the plate. When the locking assembly 5 locks the flip shaft 21, the downwardly moving locking plate 51 will be inserted into the locking groove 211 to prevent the flip shaft 21 from rotating when the clamping assembly 4 is adjusted.

[0023] The difference from the above embodiment is that the adjustment component 3 includes an adjustment rod 31, which is rotated and installed in the adjustment groove 212, wherein the end of the adjustment rod 31 close to the locking groove 211 extends out from the end of the flip shaft 21, and a hand wheel 32 is fixedly connected to the extended end of the adjustment rod 31. Rotating the hand wheel 32 can drive the adjustment rod 31 to rotate, and the adjustment rod 31 is respectively provided with threads with opposite spiral directions at both ends in the adjustment groove 212, and a sliding plate 33 is respectively installed on the threaded sections at both ends of the adjustment rod 31. When the adjustment rod 31 rotates, the sliding plate 33 is driven by the thread to move in the adjustment groove 212, and a connecting plate 331 is fixed on the sliding plate 33, and the connecting plate 331 is located in the groove of the adjustment rod 31.

[0024] Among them, during the adjustment process, when facing a larger plate size, the adjusting rod 31 is driven to rotate by rotating the hand wheel 32 in the forward direction, and the rotating adjusting rod 31 drives the two sliding plates 33 to move toward the two ends of the adjustment groove 212 respectively through the thread, thereby increasing the spacing between the clamping components 4 on the two sliding plates 33 to adapt to the larger plate size. When facing a smaller plate size, the adjusting rod 31 is driven to rotate by rotating the hand wheel 32 in the reverse direction, and the rotating adjusting rod 31 drives the two sliding plates 33 to move toward each other through the thread, and move synchronously toward the middle of the adjustment groove 212, thereby reducing the spacing between the clamping components 4 on the two sliding plates 33 to adapt to the smaller plate size.

[0025] The difference from the above embodiment is that the adjustment component 3 also includes an adjustment plate 34, which is fixedly mounted on the side of the connecting plate 331 close to the discharge conveyor belt 12, and a sliding groove 341 is opened on the adjustment plate 34, and a mounting plate 35 is fixedly connected to the adjustment plate 34, and the mounting plate 35 is located at the end of the sliding groove 341 away from the adjustment groove 212, and the adjustment screw 36 is assembled on the mounting plate 35 by means of threads, and a knob 361 is fixedly connected to the end of the adjustment screw 36 away from the sliding groove 341, and the knob 361 can be used to drive the adjustment screw 36 to rotate on the mounting plate 35.

[0026] Among them, after completing the spacing adjustment between the clamping assemblies 4 on the two sliding plates 33 and releasing the lock of the locking plate 51 on the flip shaft 21, the adjusting screw 36 can be driven to rotate by rotating the knob 361 in the forward direction, so that the end of the adjusting screw 36 facing the notch of the flip shaft 21 is away from the notch of the flip shaft 21 and gradually approaches the mounting plate 35, or the adjusting screw 36 can be driven to rotate by rotating the knob 361 in the reverse direction, so that the end of the adjusting screw 36 facing the notch of the flip shaft 21 is away from the mounting plate 35 and gradually approaches the notch of the flip shaft 21.

[0027] The difference from the above-mentioned embodiment is that the clamping assembly 4 includes an upper clamping plate 41 and a lower clamping plate 42. The upper clamping plate 41 is fixedly connected to the other side of the connecting plate 331, and the lower clamping plate 42 is slidably installed in the sliding groove 341. The lower clamping plate 42 is rotatably connected to the other end of the adjusting screw 36 toward one side of the mounting plate 35. When the adjusting screw 36 rotates, it can drive the lower clamping plate 42 to move on the adjusting plate 34.

[0028] When the adjusting screw 36 is rotated in the forward direction, the lower clamping plate 42 will be driven to slide in the sliding groove 341 toward the mounting plate 35, thereby increasing the spacing between the lower clamping plate 42 and the upper clamping plate 41. When the adjusting screw 36 is rotated in the reverse direction, the lower clamping plate 42 will be driven to slide in the sliding groove 341 toward the upper clamping plate 41, thereby reducing the spacing between the lower clamping plate 42 and the upper clamping plate 41. By cooperating with the adjusting screw 36, the clamping assembly 4 can adapt to the thickness of the new plate. After adjusting the spacing between the upper clamping plate 41 and the lower clamping plate 42 in the slot of one flip shaft 21, the flip shaft 21 is manually rotated to turn out the upper clamping plate 41 and the lower clamping plate 42 in the slot of the next flip shaft 21 for adjustment. When the spacing between the upper clamping plate 41 and the lower clamping plate 42 in the four slots on the flip shaft 21 is adjusted, the device can be started to flip the plate. During the flipping process, when the first plate is transported by the feed conveyor belt 11, it enters between the upper clamping plate 41 and the lower clamping plate 42 facing the feed conveyor belt 11 at this time, and then rotates toward the discharge conveyor belt 12 driven by the flip shaft 21. When the flip shaft 21 rotates ninety degrees, the clamping assembly 4 holding the plate is vertical, and the second empty clamping assembly 4 turns to the feed conveyor belt 11. The second plate enters the second clamping assembly 4 under the transport of the feed conveyor belt 11. As the flip shaft 21 continues to rotate ninety degrees, the first plate is flipped onto the discharge conveyor belt 12, and the second plate is vertical, and the third empty clamping assembly 4 turns to the feed conveyor belt 11. The third plate enters the third empty clamping assembly 4 under the transport of the feed conveyor belt 11, and the flip mechanism 2 repeats the above steps for production.

[0029] The difference from the above embodiment is that a connecting shaft 13 is fixed on one side of the fixing frame 1 close to the locking groove 211, one end of the locking plate 51 is rotatably connected to the connecting shaft 13, the lower side of the other end of the locking plate 51 is fixedly connected to the upper end of the supporting spring 52, the lower end of the supporting spring 52 is fixedly connected to the side wall of the fixing frame 1, the supporting spring 52 pushes the locking plate 51 upward so that the locking plate 51 is suspended above the locking groove 211, and a handle 53 is fixedly connected to the upper side of one end of the locking plate 51 connected to the supporting spring 52, and the locking plate 51 can be pushed toward the locking groove 211 through the handle 53.

[0030] Among them, when locking the flip shaft 21, first rotate the flip shaft 21 to align the locking groove 211 on the flip shaft 21 with the locking plate 51. After aligning the locking groove and the locking plate 51, stop rotating the flip shaft 21, and then push the handle 53 downward to make the locking plate 51 stuck in the locking groove 211, so that the flip shaft 21 cannot rotate, preventing the movable flip shaft 21 from affecting the rotation of the adjusting rod 31, and compressing the support spring 52. After the rotation of the adjusting rod 31 is completed, the handle 53 can be released, and the compressed support spring 52 restores its deformation to push out the locking plate 51 stuck in the locking groove 211, so that the locking plate 51 is suspended above the locking groove 211 again, thereby contacting the locking of the flip shaft 21.

[0031] Embodiment 2: The difference from the above embodiment is that the middle portion of the flip shaft 21 is in a groove shape, and a driving gear ring 213 is coaxially fixedly connected to the groove portion of the flip shaft 21 .

[0032] When the flip shaft 21 rotates, the driving gear ring 213 thereon is driven to rotate synchronously.

[0033] The difference from the above embodiment is that the transmission assembly 6 includes a mounting frame 61, which is fixedly connected to the fixing frame 1, and the mounting frame 61 is located below the pushing assembly 7. A worm 62 is rotatably mounted on the mounting frame 61, and a transmission gear 63 is coaxially fixedly connected to one end of the worm 62, and the transmission gear 63 is meshed with the driving gear ring 213.

[0034] When the driving gear ring 213 rotates, it drives the transmission gear 63 meshing with it to rotate, thereby driving the worm 62 to rotate on the mounting frame 61.

[0035] The difference from the above embodiment is that the push plate 71 is engaged with the reciprocating screw 72 through a slider, the reciprocating screw 72 is rotatably mounted on the fixed frame 1 and is located above the mounting frame 61, and a worm gear 73 is coaxially fixedly connected to one end of the reciprocating screw 72 facing the flip shaft 21, and the worm gear 73 is engaged with the worm 62.

[0036] When the worm 62 rotates, it drives the worm wheel 73 to rotate, thereby driving the reciprocating screw 72 to rotate. As the reciprocating screw 72 rotates, the push plate 71 on the reciprocating screw 72 reciprocates between the flip shaft 21 and the discharge conveyor belt 12 with the cooperation of the slider.

[0037] The difference from the above-mentioned embodiment is that a turning method for processing composite flooring uses a conveying and turning device.

[0038] Working principle: When in use, the feed conveyor belt 11 first conveys the plate to be turned over toward the turning mechanism 2. When the plate is sent to the turning mechanism 2 by the feed conveyor belt 11, the clamping assembly 4 on the turning shaft 21 corresponds to the plate. As the feed conveyor belt 11 continues to convey, the plate will enter the clamping assembly 4. After the plate enters the clamping assembly 4, the driving motor 22 drives the turning shaft 21 to rotate toward the discharge conveyor belt 12, turning over the clamped plate, and driving the driving gear ring 213 thereon to rotate synchronously. During the turning process, when the first plate is conveyed by the feed conveyor belt 11, it enters between the upper clamping plate 41 and the lower clamping plate 42 facing the feed conveyor belt 11 at this time. Then, driven by the flip shaft 21, it rotates toward the discharge conveyor belt 12. When the flip shaft 21 rotates ninety degrees, the clamping assembly 4 holding the plate is in a vertical state, and the second empty clamping assembly 4 turns to the feed conveyor belt 11. The second plate enters the second clamping assembly 4 under the conveyance of the feed conveyor belt 11. As the flip shaft 21 continues to rotate ninety degrees, the first plate is flipped onto the discharge conveyor belt 12, and the second plate becomes vertical, and the third empty clamping assembly 4 turns to the feed conveyor belt 11. The third plate enters the third empty clamping assembly 4 under the conveyance of the feed conveyor belt 11. The flip mechanism 2 repeats the above steps to produce; When the plate is turned over, there is a certain gap between the plate on the clamping assembly 4 and the turning shaft 21. The rotation of the driving gear ring 213 will drive the transmission gear 63 meshing with it to rotate, thereby driving the worm 62 to rotate on the mounting frame 61, thereby driving the reciprocating screw rod 72 to rotate. As the reciprocating screw rod 72 rotates, the push plate 71 on the reciprocating screw rod 72 reciprocates between the turning shaft 21 and the discharge conveyor belt 12 with the cooperation of the slider. For every ninety degree rotation of the turning shaft 21, the transmission assembly 6 will drive the push plate to complete a back and forth movement between the turning shaft 21 and the discharge conveyor belt 12. Initially, the push plate 71 is located next to the side wall of the fixing frame 1, close to the discharge conveyor belt 12. As the turning shaft 21 rotates, the push plate 71 will move toward the turning shaft 21. When the push plate 71 reaches the side of the turning shaft 21, the clamp The sheet on the holding assembly 4 rotates to the top of the push plate 71. At this time, the baffle 711 on the push plate 71 is inserted into the gap between the sheet and the turning shaft 21. As the turning shaft 21 continues to turn, the push plate 71 begins to move toward the discharge conveyor belt 12. During the movement, the push plate 71 drives the sheet to move in the same direction through the baffle 711, so that the sheet extends from the clamping assembly 4 to a corresponding length. When the turning shaft 21 turns the sheet over to the top of the discharge conveyor belt 12, the push plate 71 moves back to the initial position, so that the portion of the sheet extending from the clamping assembly 4 can fully contact the discharge conveyor belt 12, so that the discharge conveyor belt 12 drives the sheet to move, and promptly brings the remaining portion of the sheet out of the clamping assembly 4, and conveys the turned sheet to the next process. Then the turning shaft 21 continues to rotate to turn the next sheet onto the discharge conveyor belt 12. When it is necessary to flip plates of other sizes, before opening the device, first rotate the flip shaft 21 to align the locking groove 211 on the flip shaft 21 with the locking plate 51. After aligning the locking groove and the locking plate 51, stop rotating the flip shaft 21, and then push the handle 53 downward to make the locking plate 51 snap into the locking groove 211, so that the flip shaft 21 cannot rotate, preventing the movable flip shaft 21 from affecting the rotation of the adjusting rod 31, and compressing the supporting spring 52. When facing plates of larger sizes, the adjusting rod 31 is driven to rotate by rotating the hand wheel 32 forward, and the rotating adjusting rod 31 drives the two sliding plates 33 to move toward the two ends of the adjusting groove 212 respectively through the thread, thereby increasing the spacing between the clamping components 4 on the two sliding plates 33 to adapt to plates of larger sizes. When facing plates of smaller sizes, the adjusting rod 31 is driven to rotate by rotating the hand wheel 32 in the opposite direction, and the rotating adjusting rod 31 drives the two sliding plates 33 toward each other through the thread.
