When the support frame approaches the stand, the arc-shaped block is in contact with the arc-shaped push plate II again and slides along the arc-shaped push plate II, at this time, the arc-shaped block approaches the abutment plate again and drives the positioning plate to release the clamping of the board, thereby facilitating the clamping of the board.

[0011] Optionally, the abutting plate is fixedly connected with a slide bar along the length direction, both slide blocks are provided with through holes matched with the slide bar, and the slide blocks are circumferentially provided with a plurality of groups of pulleys along the through holes, the pulleys are rotationally connected with the slide blocks, and in each group of pulleys, the number of pulleys is at least two, the slide bar sequentially penetrates the through holes of both slide blocks, the slide bar is provided with slide grooves matched with the pulleys along the length direction, and the pulleys are located in the corresponding slide grooves and are rollingly connected with the slide bar.

[0012] By adopting the above technical scheme, the slide bar and the through hole cooperate to limit the slide block, so that the slide block moves along the length direction of the slide bar, the slide block drives the pulley to roll along the slide groove when moving, thereby reducing the friction between the slide block and the slide bar and improving the moving stability of the slide block.

[0015] Optionally, the abutting plate is provided with a limiting tube close to one end of the arc-shaped block, the abutting plate is fixedly connected with a positioning ring matched with the limiting tube, the limiting tube penetrates the positioning ring and is rotationally connected with the positioning ring along the circumference of the positioning ring, an elastic member two is arranged between the positioning ring and the limiting tube, the elastic member two is used for positioning the rotation of the limiting tube, a baffle is fixedly connected to one end of the limiting tube close to the arc-shaped block, the arc-shaped block is fixedly connected with a stop plate matched with the baffle, the baffle and the stop plate are opposite in the natural state of the elastic member two, a rotating plate is fixedly connected to the outer circle of the limiting tube, an arc-shaped push plate one is fixedly connected to one side close to the abutting plate with a driving block one matched with the rotating plate, and an arc-shaped push plate two is fixedly connected with a driving block two matched with the rotating plate.

[0016] By adopting the above technical scheme, the abutment plate is limited by the positioning ring to the limiting tube, and the positioning ring limits the circumferential rotation of the limiting tube by the elastic element two. When the arc-shaped block does not interfere with the arc-shaped push plate one and the arc-shaped push plate two, the baffle is opposite to the stop plate. At this time, the arc-shaped block is located away from the abutment plate, and the limiting tube positions the stop plate and the arc-shaped block through the baffle, thereby improving the compression stability of the positioning plate to the plate. When the arc-shaped block moves towards the arc-shaped push plate one, the limiting tube drives the rotating plate to move close to the driving block one and interferes with the driving block one. At this time, the driving block one drives the limiting tube to deflect through the rotating plate, so that the limiting tube drives the baffle to deviate from the stop plate, thereby releasing the limiting of the arc-shaped block. At this time, the arc-shaped block interferes with the arc-shaped push plate one and gradually moves towards the abutment plate. When the arc-shaped block is separated from the arc-shaped push plate one, the rotating plate is separated from the driving block one.

The extension plate is threadedly connected with an abutment bolt away from one end thereof. The abutment bolt abuts against the clamping plate through the extension plate.

[0018] By adopting the above technical scheme, the extension plate limits the rotating column through the limiting slot, so that the positioning plate is connected with the moving plate and the extension plate. When the moving plate is rotated, the moving plate drives the rotating column to move along the limiting slot. At this time, the extension plate moves towards or away from the positioning plate. When the abutment bolt is rotated, the abutment bolt pushes the clamping plate to interfere with the rotating column, thereby making the clamping plate and the extension plate cooperate to clamp and position the rotating column. The extension plate is used to compress and position the plate, thereby improving the positioning effect of the positioning plate.

[0019] Optionally, the vertical frame is hingedly connected with a swing plate. The vertical frame is provided with a moving block corresponding to the swing plate.

One end of the connecting plate away from the moving block is hingedly connected with the swing plate. The swing plate is rotationally connected with a clamping plate away from one end of the vertical frame. The clamping plate and the swing plate are provided with an elastic element three. In a natural state, the swing plate is parallel to the clamping plate.

[0020] Through the above technical scheme, under the support of the vertical frame, the air cylinder drives the moving block to move vertically, and the moving block drives the swing plate to swing through the connecting plate when moving, and when the swing plate approaches the support frame, the clamping plate is brought into close contact with the plate, at this time, the swing plate and the clamping plate rotate relative to each other, so that the elastic member three is deformed, and the support frame is flipped, and the plate is clamped and positioned by the clamping plate in the process, which is beneficial to further improve the stability of the plate in the flipping process.

[0021] Optionally, the end of the support frame away from the vertical frame is provided with a limiting block, the limiting block is provided with a straight rod, the straight rod passes through the limiting block and is in sliding connection with the limiting block, one end of the straight rod close to the vertical frame is fixedly connected with an arc-shaped plate, an elastic member four is arranged between the arc-shaped plate and the limiting block, and the elastic member four is used to push the arc-shaped plate away from the limiting block.

[0022] Through the above technical scheme, under the support of the vertical frame, the air cylinder drives the moving block to move vertically, and the moving block drives the swing plate to swing through the connecting plate when moving, and when the swing plate approaches the support frame, the clamping plate is brought into close contact with the plate, at this time, the swing plate and the clamping plate rotate relative to each other, so that the elastic member three is deformed, and the support frame is flipped, and the plate is clamped and positioned by the clamping plate in the process, which is beneficial to further improve the stability of the plate in the flipping process.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] 1. In the initial state, the support frame is in a horizontal state, at this time, the arc-shaped block is pushed towards the abutment plate, the arc-shaped block drives the elastic member one to compress, the arc-shaped block moves through the connecting rod to drive the pull rod to move, under the limiting action of the abutment plate, the pull rod moves to drive the two sliding blocks to approach each other, at this time, the sliding rod drives the pressing plate away from the support frame through the push plate, the pressing plate moves to drive the positioning plate to move synchronously. A plurality of wooden plates are arranged on the upper end of the support frame, at this time, the plates are located between the pressing plate and the support frame, the positioning of the arc-shaped block is released, the arc-shaped block is driven away from the abutment plate by the elastic member one, the arc-shaped block moves through the connecting rod and the pull rod to drive the two sliding blocks to move away from each other, the sliding block moves to drive the pressing plate to approach the support frame through the push plate, and the pressing plate is in contact with the plate, and the plate is pressed on the support frame, thereby improving the stability of the plate in the flipping process, and improving the safety of the flipped plate in the flipping process.

[0025] 2. The abutment plate limits the limiting tube through the positioning ring, and the positioning ring limits the circumferential rotation of the limiting tube through the elastic member two. When the arc-shaped block does not interfere with the arc-shaped push plate one and the arc-shaped push plate two, the baffle is opposite to the stop plate. At this time, the arc-shaped block is located away from the abutment plate, and the limiting tube positions the stop plate and the arc-shaped block through the baffle, thereby improving the compression stability of the positioning plate to the plate. When the arc-shaped block moves towards the arc-shaped push plate one, the limiting tube drives the rotating plate to move close to the driving block one and interferes with the driving block one. At this time, the driving block one drives the limiting tube to deflect through the rotating plate, so that the limiting tube drives the baffle to deviate from the stop plate, thereby releasing the limiting of the arc-shaped block. At this time, the arc-shaped block interferes with the arc-shaped push plate one and gradually moves towards the abutment plate. When the arc-shaped block is separated from the arc-shaped push plate one, the rotating plate is separated from the driving block one. At this time, the elastic member two drives the limiting tube to reset. When the arc-shaped block moves towards the arc-shaped push plate two, the arc-shaped push plate two drives the limiting tube to deflect through the driving block two, thereby releasing the limiting of the limiting tube at the arc-shaped push plate two;

[0026] 3. Under the support of the vertical frame, the push cylinder drives the moving block to move vertically. When the moving block moves, it drives the swing plate to swing through the connecting plate. When the swing plate moves close to the support frame, it drives the clamping plate to be attached to the plate. At this time, the swing plate and the clamping plate rotate relative to each other, so that the elastic member three deforms. During the overturning process of the support frame, the plate is clamped and positioned by the clamping plate, which is conducive to further improving the stability of the plate during the overturning process.

The straight rod 32 and the arc-shaped plate 33 are driven to move when the limiting block 31 moves. In the horizontal state of the support frame 3, the arc-shaped plate 33 is located at one end of the straight rod 32 close to the vertical frame 2.

When the spring is compressed, the arc-shaped plate 33 is pushed to move away from the limiting block 31.

[0040] With reference to Figure 1 and Figure 3 One side of the support frame 3 is fixedly connected with an abutment plate 4. One end of the support frame 3 away from the abutment plate 4 is provided as a feeding end. When the wooden plates are placed above the support frame 3, the end portions of all the plates are in contact with the abutment plate 4, and the plates close to the vertical frame 2 are in contact with the blocking plate. The blocking plate limits the support frame 3. At this time, the plates are located between the arc-shaped plate 33 and the blocking plate, and the elastic member four 34 is in a compressed state, so that the arc-shaped plate 33 and the blocking plate cooperate to clamp and position the plates.

[0041] With reference to Figure 1 and Figure 3 One side of the abutment plate 4 away from the support frame 3 is fixedly connected with a sliding rod 45. The sliding rod 45 is arranged in parallel with the abutment plate 4. The abutment plate 4 is provided with two sliding blocks 41. The sliding blocks 41 are each provided with a through hole 412 adapted to the sliding rod 45. The sliding rod 45 passes through the through hole 412 of the sliding block 41 and is in sliding connection with the sliding block 41. The sliding rod 45 cooperates with the through hole 412 to limit the sliding block 41, so that the sliding block 41 moves along the length direction of the sliding rod 45.

[0042] With reference to Figure 1 and Figure 3 Four groups of pulleys 413 are uniformly arranged in the axial direction of the through hole 412. The pulleys 413 are in rotary connection with the sliding block 41. The sliding block 41 drives the pulleys 413 to move. The sliding rod 45 is provided with four sliding grooves 451 adapted to the pulleys 413 along the length direction. The pulleys 413 are located in the corresponding sliding grooves 451 and are in rolling connection with the sliding rod 45 along the length direction of the sliding grooves 451. The pulleys 413 are beneficial to reduce the friction between the sliding block 41 and the sliding rod 45, thereby improving the moving stability of the sliding block 41 and the sliding rod 45 and prolonging the service life of the sliding block 41 and the sliding rod 45.

[0043] With reference to Figure 1 and Figure 3The lower end of the abutting plate 4 is provided with a connecting rod 42, the two sliding blocks 41 are centrally symmetrically arranged with the connecting rod 42, the connecting rod 42 is perpendicular to the abutting plate 4, the connecting rod 42 is slidingly connected with the abutting plate 4 along the axial direction, one end of the connecting rod 42 away from the abutting plate 4 is fixedly connected with an arc-shaped block 421, and the arc-shaped block 421 drives the abutting rod to move when the arc-shaped block 421 moves. Two pull rods 422 are hingedly connected to one end of the connecting rod 42 away from the arc-shaped block 421, the pull rod 422 corresponds to the sliding block 41 in a one-to-one manner, and the two pull rods 422 are centrally symmetrically arranged with the connecting rod 42. When the connecting rod 42 moves, the pull rod 422 moves.

[0044] With reference to Figure 3 and Figure 4 One end of the pull rod 422 away from the connecting rod 42 is hingedly connected with the corresponding sliding block 41, and the pull rod 422 is arranged to be inclined. When the pull rod 422 moves, the sliding block 41 moves along the slide rod 45. The connecting rod 42 and the abutting plate 4 are provided with an elastic member 423, the elastic member 423 is a spring, one end of the spring is fixedly connected with the connecting rod 42, and the other end is fixedly connected with the abutting plate 4. The spring is in a compressed state, and pushes the arc-shaped block 421 away from the abutting plate 4. At this time, the two sliding blocks 41 are away from each other.

[0045] With reference to Figure 1 and Figure 5 The upper end of the sliding block 41 is rotatably connected with a push plate 411, and the two push plates 411 are hingedly connected with the same pressing plate 43. When the two sliding blocks 41 are away from each other, the pressing plate 43 is driven by the push plate 411 to move close to the support frame 3. The pressing plate 43 extends towards the support frame 3 and is provided with a positioning plate 44 located on the side of the pressing plate 43 close to the support frame 3. The upper end of the positioning plate 44 is rotatably connected with an adjusting rod 442, the adjusting rod 442 drives the positioning plate 44 to move when the adjusting rod 442 moves, the adjusting rod 442 is arranged perpendicularly to the positioning plate 44, and a threaded rod 443 is coaxially fixed to one end of the adjusting rod 442 away from the positioning plate 44. The threaded rod 443 penetrates through the pressing plate 43 and is threadedly connected with the pressing plate 43. When the pressing plate 43 moves, the positioning plate 44 is driven by the threaded rod 443 and the adjusting rod 442 to move.

[0046] With reference to Figure 1 and Figure 5 The upper end of the positioning plate 44 is further fixedly connected with two guide rods 441, the adjusting rod 442 is located between the two guide rods 441, and the adjusting rod 442 is parallel to the guide rods 441. The guide rod 441 penetrates through the pressing plate 43 and is slidingly connected with the pressing plate 43. Under the limiting action of the guide rod 441, when the threaded rod 443 is rotated, the threaded rod 443 pushes the positioning plate 44 to move close to or away from the pressing plate 43 along the axial direction of the threaded rod 443, thereby facilitating the adjustment of the distance between the positioning plate 44 and the pressing plate 43.

[0047] With reference to Figure 1 and Figure 3, the upper end of the workbench 1 is fixed with an arc-shaped push plate 11, and the arc-shaped push plate 11 corresponds to the arc-shaped block 421, when the support frame 3 is turned over by the turnover cylinder, the abutment plate 4 drives the arc-shaped block 421 to move along the arc-shaped push plate 11 through the connecting rod 42. The arc-shaped push plate 11 is inclined along the length direction, the arc-shaped block 421 is in contact with the arc-shaped push plate 11, and when the arc-shaped block 421 moves along the arc-shaped push plate 11 to the workbench 1, the arc-shaped push plate 411 drives the arc-shaped block 421 to gradually move to the abutment plate 4, at this time the elastic element 423 is further compressed.

[0048] Referring to Figure 1 and Figure 3 , when the support frame 3 is in a horizontal state, the arc-shaped block 421 is in a position close to the abutment plate 4, when the arc-shaped block 421 moves to the abutment plate 4, the two pull rods 422 are driven to rotate through the connecting rod 42, so that the pull rod 422 drives the two sliding blocks 41 to move close to each other, when the sliding block 41 moves, the pressing plate 43 is driven away from the support frame 3 through the push plate 411. At this time, the board is placed on the support frame 3, so that the board is located between the positioning plate 44 and the support frame 3.

[0049] Referring to Figure 1 and Figure 3 , after the board is placed, the support frame 3 is driven to move close to the vertical frame 2 by the turnover cylinder, the support frame 3 moves through the abutment plate 4 to drive the connecting rod 42 and the arc-shaped block 421 to move, so that the arc-shaped block 421 moves away from the workbench 1 along the arc-shaped push plate 11, at this time the arc-shaped block 421 gradually moves away from the abutment plate 4 under the action of the elastic element 423, when the arc-shaped block 421 is separated from the arc-shaped push plate 11, the arc-shaped block 421 is in a position away from the abutment plate 4. When the arc-shaped block 421 moves away from the abutment plate 4, the two sliding blocks 41 are driven to move away from each other, and then the push plate 411 drives the positioning plate 44 to move close to the board through the pressing plate 43, when the positioning plate 44 is in contact with the board, the board is clamped and positioned in cooperation with the support frame 3, which is helpful to reduce the probability of accidental falling of the board during the turnover process of the support frame 3, and then is helpful to improve the safety of the turnover board during the turnover process.

[0050] Referring to Figure 1 and Figure 3The vertical frame 2 is fixedly connected with an arc-shaped push plate two 21 corresponding to the arc-shaped push plate one 11. After the arc-shaped block 421 is separated from the arc-shaped push plate one 11, the arc-shaped block 421 gradually approaches the arc-shaped push plate two 21. When the support frame 3 approaches the vertical frame 2, the arc-shaped block 421 is brought into abutment with the arc-shaped push plate two 21 and the arc-shaped block 421 is moved along the arc-shaped push plate two 21. At this time, the arc-shaped block 421 is again close to the abutment plate 4 under the action of the arc-shaped push plate two 21. When the arc-shaped block 421 moves, the pressing plate 43 and the positioning plate 44 are away from the support frame 3, thereby releasing the limiting of the plate, and the plate after turning is moved to the downward work station. The clamping and loosening of the plate by the positioning plate 44 do not need manual operation, thereby improving the work convenience.

[0051] With reference to Figure 1 and Figure 5 , the side, away from the arc-shaped block 421, of the positioning plate 44 is provided in parallel with an extension plate 6. Two moving plates 47 are arranged between the positioning plate 44 and the extension plate 6. One end of the moving plate 47 is hingedly connected with the positioning plate 44, and the other end is fixedly connected with a rotating column 471. The positioning plate 44 moves to drive the moving plate 47 and the rotating column 471 to move. The rotating column 471 is arranged perpendicularly to the moving plate 47, and the lower end of the rotating column 471 is fixedly connected with a rotating disc. The extension plate 6 is provided with a limiting groove 61 along the length direction. The rotating column 471 and the rotating disc are both arranged in the limiting groove 61 and are slidably connected with the extension plate 6 along the length direction of the limiting groove 61.

[0052] With reference to Figure 1 and Figure 5 , in the initial state, the moving plate 47 is arranged obliquely to the positioning plate 44. At this time, the extension plate 6 is close to the positioning plate 44. When the moving plate 47 is rotated to the angle perpendicular to the positioning plate 44, the extension plate 6 is driven by the rotating column 471 to move away from the positioning plate 44. The extension plate 6 is provided with a clamping plate 62. The clamping plate 62 is arranged in the limiting groove 61 and is slidably connected with the extension plate 6 along the width direction of the limiting groove 61. The extension plate 6 moves to drive the clamping plate 62 to move. The rotating disc is in abutment with the clamping plate 62. The side, away from the positioning plate 44, of the extension plate 6 is threadedly connected with an abutment bolt 63. The abutment bolt 63 is in abutment with the clamping plate 62 through the extension plate 6.

[0053] With reference to Figure 1 and Figure 5 , in the initial state, the abutment bolt 63 is away from the clamping plate 62. After the extension plate 6 is moved to the appropriate position, the abutment bolt 63 is rotated to drive the clamping plate 62 to abut against the rotating disc. At this time, the clamping plate 62 cooperates with the extension plate 6 to limit the movement of the rotating disc, thereby positioning the extension plate 6 by the two moving plates 47. When the positioning plate 44 moves, the extension plate 6 is in abutment with the plate through the moving plate 47. The extension plate 6 is beneficial to improve the pressing stability of the positioning plate 44 to the plate, thereby further improving the limiting effect of the plate.

[0054] With reference to Figure 3 and Figure 4 , the abutment plate 4 is fixedly connected with a positioning ring 46 close to one end of the arc-shaped block 421, the connecting rod 42 passes through the positioning ring 46 along the axis direction of the positioning ring 46, a limiting tube 51 is rotationally connected to the inner side of the positioning ring 46, the limiting tube 51 is sleeved on the outer side of the connecting rod 42, and the arc-shaped block 421 approaches or moves away from the limiting tube 51 when the connecting rod 42 moves along the axis direction. An elastic member two 52 is arranged between the positioning ring 46 and the limiting tube 51, the elastic member two 52 is a torsion spring, one end of the torsion spring is fixedly connected with the positioning ring 46, the other end is fixedly connected with the limiting tube 51, and the positioning ring 46 limits the rotation of the limiting tube 51 in the circumferential direction through the elastic member two 52.

[0055] With reference to Figure 2 and Figure 4 , the limiting tube 51 is fixedly connected with a baffle 53 close to one end of the arc-shaped block 421, and the arc-shaped block 421 is fixedly connected with a stop plate 424 matched with the baffle 53. When the arc-shaped block 421 is located between the arc-shaped push plate one 11 and the arc-shaped push plate two 21, the elastic member two 52 is in a natural state, and at this time, the baffle 53 is opposite to the stop plate 424. The limiting tube 51 positions the stop plate 424 through the baffle 53, thereby limiting the tendency of the arc-shaped block 421 to approach the abutment plate 4, and thereby improving the clamping stability of the positioning plate 44 to the plate during the overturning process of the support frame 3.

[0056] With reference to Figure 2 and Figure 3 , the outer circle of the limiting tube 51 is fixedly connected with a rotating plate 54, and the arc-shaped push plate one 11 is fixedly connected with a pushing block one 111 corresponding to the rotating plate 54. When the support frame 3 rotates towards the workbench 1, the limiting tube 51 drives the rotating plate 54 to move towards the pushing block one 111. After the pushing block one 111 is in contact with the rotating plate 54, the pushing block one 111 drives the rotating plate 54 to move, thereby causing the rotating plate 54 to drive the limiting tube 51 to rotate along the circumferential direction of the limiting tube 51.

[0057] With reference to Figure 1 and Figure 4 , the limiting tube 51 drives the baffle 53 to be dislocated from the stop plate 424 when the limiting tube 51 rotates, thereby causing the elastic member two 52 to deform. At this time, the arc-shaped block 421 is in contact with the arc-shaped push plate one 11, and approaches the abutment plate 4 under the action of the arc-shaped push plate one 411. The arc-shaped push plate two 21 is fixedly connected with a pushing block two 211 corresponding to the pushing block one 111. When the support frame 3 approaches the vertical frame 2, the pushing block two 211 drives the limiting tube 51 to rotate in cooperation with the rotating plate 54, thereby releasing the limiting of the arc-shaped block 421.

[0058] With reference to Figure 1 and Figure 6, The swing plate 71 is hinged to the position close to the workbench 1, and is provided with multiple groups. The vertical frame 2 is vertically and slidingly connected with the moving block 72 corresponding to the swing plate 71. The moving block 72 is hinged with the connecting plate 74, and the end of the connecting plate 74 away from the moving block 72 is hinged with the swing plate 71. The swing plate 71 is swung by the connecting plate 74 when the moving block 72 moves vertically, and then the swing plate 71 is close to or away from the support frame 3. The vertical frame 2 is provided with the push cylinder 73, and the output end of the push cylinder 73 is fixedly connected with the moving block 72, so as to drive the moving block 72 to move vertically.

[0059] Referring to Figure 1 and Figure 6 , the end of the swing plate 71 away from the vertical frame 2 is rotationally connected with the clamping plate 75. The swing plate 71 drives the clamping plate 75 to move when the swing plate 71 moves. The elastic member four 34 is arranged between the swing plate 71 and the clamping plate 75, and the elastic member four 34 is a torsion spring. One end of the torsion spring is fixedly connected with the swing plate 71, and the other end is fixedly connected with the clamping plate 75. In the natural state of the torsion spring, the swing plate 71 and the clamping plate 75 are in a parallel state. When the swing plate 71 is close to the support frame 3, the clamping plate 75 is brought into contact with the plate, and a certain angle is formed between the clamping plate 75 and the swing plate 71. At this time, the elastic member four 34 is in a deformed state. The clamping plate 75 cooperates with the support frame 3 to clamp and position the plate, which is beneficial to further reduce the probability of the plate falling during the turning process.

[0060] The implementation principle of the anti-falling mechanism of the tile splicing machine is as follows: when the support frame 3 is in a horizontal state, the arc-shaped block 421 is in contact with the arc-shaped push plate 411, and at this time, the positioning plate 44 is away from the support frame 3. The plate is placed between the support frame 3 and the positioning plate 44 along the loading end of the support frame 3. Under the drive of the elastic member four 34, the arc-shaped plate 33 cooperates with the blocking plate to clamp the plate. When the support frame 3 turns the plate, the arc-shaped block 421 is away from the workbench 1 along the arc-shaped push plate 411. At this time, the elastic member one 423 drives the arc-shaped block 421 to be away from the abutting plate 4. When the arc-shaped block 421 moves, the connecting rod 42 drives the pull rod 422 to move. When the pull rod 422 moves, the two sliding blocks 41 are away from each other. When the sliding block 41 moves, the push plate 411 drives the pressing plate 43 and the positioning plate 44 to be close to the support frame 3, so that the positioning plate 44 cooperates with the support frame 3 to clamp and position the plate, thereby reducing the probability of the plate falling during the turning process, and thereby improving the safety of the plate during the turning process.

[0061] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
