[0002] In the production process of gypsum board, the gypsum board after drying treatment needs to enter the edge sawing process. This process usually relies on a pushing device to push the gypsum board to a slitting saw arranged side by side for slitting. During the pushing process of the pushing device, the gypsum board must always move perpendicular to the edge of the slitting saw to avoid the slitting of the gypsum board edge as much as possible.

[0003] The commonly used pushing device in the industry is generally a plurality of push plate chains arranged side by side upstream of the slitting saw. Each push plate chain has a plurality of push plate claws equally spaced on the outer circle. Each row of push plate claws is on the same horizontal line. Each push plate chain has an independent driving device to control rotation. The gypsum board to be slitted is conveyed to the push plate chain, and the push plate chain drives the push plate claw to move at the same speed. One row of push plate claws pushes the gypsum board onto the rotating slitting saw to complete the slitting of the gypsum board.

[0004] The push plate chain of the prior art is prone to tooth skipping failure during long-term operation, causing the push plate claws originally aligned horizontally to deviate from the same reference line. To solve this problem, the operator adjusts the speed of the push plate chain through the driving device to adjust the push plate claws to the same horizontal line, which requires the operator to be on duty without interruption, and the operation process is complicated.

[0049] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0050] As shown in Figure 1 , Figure 2 , the present application provides a pushing device for gypsum board dry board saw edge, which has:

[0051] The receiving platform 21 is used for receiving the gypsum board conveyed from the upstream thereof;

[0052] The centering pushing device 22 is arranged on both sides of the receiving platform 21, and the two centering pushing devices 22 are used for synchronously applying force to the two sides of the gypsum board after the gypsum board is conveyed to the receiving platform 21, so as to push the gypsum board to the middle region of the receiving platform 21;

[0053] The pushing plate 23 is arranged on the receiving platform 21, and a plurality of pushing plates 23 are equidistantly arranged on the same horizontal line along the direction perpendicular to the transportation direction of the gypsum board to form a horizontal pushing surface;

[0054] The connecting rod 24 is connected to the top of each pushing plate 23;

[0055] The linear reciprocating driving device 25 is connected to each connecting rod 24, and the linear reciprocating driving device 25 is used for driving each connecting rod 24 to move synchronously and at the same speed, so that each pushing plate 23 moves simultaneously along the direction perpendicular to the horizontal pushing surface at the same speed, so that the horizontal pushing surface tightly abuts against the side surface of the gypsum board and applies pushing force;

[0056] Lifting adjustment device 26 is arranged above one side of receiving platform 21, after the completion of one pushing action of push plate 23 reset, lifting adjustment device 26 drives each connecting rod 24 to rise, each connecting rod 24 drives the push plate 23 at the bottom to rise, so that each push plate 23 away from the surface of receiving platform 21, so that the next gypsum board is transported to receiving platform 21.

[0057] In the present application, a plurality of push plates 23 are connected with the same linear reciprocating drive device 25 through connecting rods 24, and the same power source, so that all connecting rods 24 move synchronously and at the same speed, and then all connecting rods 24 drive all push plates 23 to move synchronously and at the same speed, ensuring that all push plates 23 always maintain the same horizontal pushing surface, and avoiding the misalignment of push plates 23 as much as possible, and the push plate 23, the connecting rod 24 and the linear reciprocating drive device 25 are rigidly connected, and the fixed connection structure makes the power of the linear reciprocating drive device 25 be transmitted to each push plate 23 without loss and lag, thereby reducing the error rate from the structure and simplifying the operation process without manual supervision.

[0058] The embodiment mainly aims at the problem that the gypsum board is prone to tilt (the gypsum board moves not perpendicular to the cutting direction of the slitting saw) during the pushing process after the gypsum board is dried and enters the edge sawing process, and proposes a pushing device for gypsum board drying and edge sawing.

[0059] Specifically, the gypsum board is received by the receiving platform 21, the centering pushing device 22 positions the gypsum board, a plurality of push plates 23 are rigidly connected with the linear reciprocating drive device 25 through connecting rods 24 to form a horizontal pushing surface, and the gypsum board is synchronously pushed to the cutting direction, after the slitting of one gypsum board is completed, the lifting adjustment device 26 drives all push plates 23 to rise and reset, without interfering with the feeding of the next gypsum board, and the pushing is accurate and continuous.

[0060] The centering pushing device 22 can adjust the moving stroke according to the width of the produced gypsum board, so as to avoid excessive extrusion and deformation of the gypsum board as much as possible, and in addition, all push plates 23 can adjust the stroke through the linear reciprocating drive device 25, so as to adapt to the pushing requirements of gypsum boards of different lengths.

[0061] Each connecting rod 24 is arranged at the top middle position of the push plate 23, so that the driving force of the linear reciprocating drive device 25 and the lifting adjustment device 26 directly acts on the central area of the push plate 23, the stress point of the push plate 23 coincides with the center of gravity, and unilateral stress concentration is not generated due to stress deviation during the pushing or lifting process, thereby effectively avoiding the inclination and torsion of the push plate 23, and in addition, the pushing force of the push plate 23 on the gypsum board is evenly distributed, so as to prevent the inclination or deformation during the pushing process.

[0062] For example, Figure 2As shown, the linear reciprocating driving device 25 is used to provide linear reciprocating power to the push plate 23 to push the gypsum board in the cutting direction and bring the push plate 23 back to the original position after the gypsum board is cut, so as to push the next gypsum board. The linear reciprocating driving device 25 comprises:

[0063] The translation connecting plate 250 is arranged transversely on one side of the connecting rod 24.

[0064] The circumferential limiting lug 251 is arranged on the side of the translation connecting plate 250 close to the connecting rod 24, and the circumferential limiting lug 251 is arranged in one-to-one correspondence with the connecting rod 24. Each circumferential limiting lug 251 has a vertically penetrating lug hole, and one connecting rod 24 penetrates one lug hole.

[0065] The connecting push plate 252 is fixedly arranged on the side of the translation connecting plate 250 away from the circumferential limiting lug 251 by means of screws.

[0066] The driving end of the driving cylinder 253 is connected to the side of the connecting push plate 252 away from the translation connecting plate 250.

[0067] The driving cylinder 253 drives the linear motion of the connecting push plate 252, and the connecting push plate 252 drives the linear motion of the translation connecting plate 250, and the translation connecting plate 250 simultaneously drives the linear motion of the plurality of connecting rods 24 and the push plate 23.

[0068] The driving cylinder 253 transmits power to the translation connecting plate 250 through the connecting push plate 252. The translation connecting plate 250 acts as a unified power distribution component and synchronously drives the motion of all the connecting rods 24 and the push plate 23 connected by the circumferential limiting lug 251, realizes the transmission of "single power source→ unified bearing→ multiple component synchronous action", and ensures that all the push plates 23 always maintain the same speed and the same trajectory, strengthens the integrity of the horizontal pushing surface, and improves the pushing precision of the gypsum board.

[0069] The inner wall contour of the lug hole is matched with the outer wall contour of the connecting rod 24 to limit the translation, rotation and offset motion of the connecting rod 24 in the lug hole.

[0070] The lug hole of the circumferential limiting lug 251 only limits the transverse position of the connecting rod 24, and further realizes the vertical lifting of the connecting rod 24 and the push plate 23 through the subsequent lifting adjusting device 26, so as to facilitate the feeding of the next gypsum board. When the push plate 23 pushes the gypsum board, the reverse force of the gypsum board on the push plate 23 is a transverse force. The lug hole limits the transverse position of the connecting rod 24, so that the push plate 23 is not affected by the reverse force of the gypsum board, and the horizontal pushing surface formed by the push plate 23 is not inclined, further avoiding the inclination of the gypsum board.

[0071] As shown in FIG. 6, the driving cylinder 253 is arranged on the side of the connecting push plate 252 away from the translation connecting plate 250. Figure 3、 Figure 4 As shown in the drawings, after the driving cylinder 253 pushes each push plate 23 to complete the cutting of a gypsum board, each push plate 23 is pulled back, at this time, the lifting adjusting device 26 drives each push plate 23 to rise, so that each push plate 23 is away from the bearing surface of the receiving platform 21, so as to facilitate the next gypsum board to be conveyed to the receiving platform 21. Therefore, the lifting adjusting device 26 comprises:

[0072] An adjusting box 260 is horizontally arranged above the receiving platform 21;

[0073] A driving shaft 261 is arranged inside the adjusting box 260 along the length direction of the adjusting box 260;

[0074] A plurality of driving gears 262 are arranged along the axial direction of the driving shaft 261;

[0075] A plurality of right-angle openings 263 are arranged at the connection between the bottom and the side wall of the adjusting box 260, each right-angle opening 263 is arranged opposite to a connecting rod 24, and each driving gear 262 is arranged opposite to a right-angle opening 263;

[0076] A rectangular tooth 264 is vertically arranged on the side wall of each connecting rod 24;

[0077] After the push plate 23 completes a pushing action, the linear reciprocating driving device 25 drives each connecting rod 24 to pass through the opposite right-angle opening 263 and reset inside the adjusting box 260, and in the reset state, each rectangular tooth 264 is engaged with the opposite driving gear 262;

[0078] A plurality of through holes 266 are arranged on the top of the adjusting box 260 opposite to the end of each connecting rod 24 in the reset state, and the position of the through hole 266 corresponds to the engagement area of the rectangular tooth 264 and the driving gear 262.

[0079] The driving cylinder 253 pulls back each push plate 23 through the connecting rod 24, and the driving gear 262 is arranged at a position just making the rectangular tooth 264 and the driving gear 262 in the engagement state when the push plate 23 is reset.

[0080] The right-angle opening 263 at the connection between the bottom and the side wall of the adjusting box 260 not only provides a channel for the connecting rod 24 to reset into the adjusting box 260, but also guides the horizontal reset movement of the connecting rod 24, so as to ensure that the rectangular tooth 264 is engaged with the driving gear 262 after reset.

[0081] The lifting adjusting device 26 further comprises:

[0082] The driving motor 265 is arranged on the outer wall of the adjusting box 260, the driving end of the driving motor 265 penetrates into the adjusting box 260 and is connected with the driving shaft 261, the driving motor 265 is used for driving the driving shaft 261 to rotate, the driving shaft 261 drives the plurality of driving gears 262 to rotate, the driving gears 262 drive the rectangular tooth 264 and the connecting rod 24 to move upward, each connecting rod 24 drives the push plate 23 at the bottom thereof to move upward, and the top of the rectangular tooth 264 and the connecting rod 24 penetrates out of the adjusting box 260 from the penetration opening 266.

[0083] After the driving cylinder 253 drives each push plate 23 to reset, the driving motor 265 is started and drives each connecting plate and push plate 23 to rise by driving the plurality of driving gears 262 to rotate.

[0084] The penetration opening 266 at the top of the adjusting box 260 is opposite to the end of the connecting rod 24 in the reset state, thereby providing vertical movement space for the rising of the connecting rod 24 and preventing the interference of the box body of the adjusting box 260 on the lifting of the connecting rod 24.

[0085] The ear hole of the above-mentioned circumferential side limiting lug 251 only limits the horizontal movement of the connecting rod 24, and the structure is matched with the driving motor 265 which can drive the push plate 23 to move vertically by driving the connecting rod 24.

[0086] However, the connecting rod 24 may be slightly shaken up and down in the vertical direction in the process of pushing the gypsum board, and the push plate 23 is also slightly shaken up and down, in order to prevent the push plate 23 from being slightly shaken up and down in the process of pushing the gypsum board, a vertical limiting guide rail 27 is arranged on one side of each right-angle opening 263 along the direction of the transportation of the gypsum board, and the vertical limiting guide rail 27 is used for limiting the vertical movement of the connecting rod 24 in the process of pushing the gypsum board by the push plate 23.

[0087] Specifically, as shown in Figure 3 Each vertical limiting guide rail 27 is provided with a downward-opening groove 28 along the length direction thereof, and the top of the connecting rod 24 is slidingly arranged in the groove 28.

[0088] In the process of pushing the gypsum board by the push plate 23, the top of the connecting rod 24 is clamped in the groove 28, so that the groove 28 limits the vertical movement of the connecting rod 24, thereby preventing the push plate 23 from being slightly shaken up and down in the process of pushing the gypsum board.

[0089] Further, the vertical height between the top of the groove 28 and the receiving platform 21 is equal to the height from the top of the connecting rod 24 to the bottom of the push plate 23, and the limiting of the top of the groove 28 and the receiving platform 21 further ensures that when the push plate 23 pushes the gypsum board, the reaction force of the gypsum board on the push plate 23 will not cause the push plate 23 to tilt backward, and the transverse limiting of the circumferential limiting ear maximizes the guarantee that the horizontal pushing surface formed by the push plate 23 is entirely attached to the side wall of the gypsum board, preventing the gypsum board from being pushed to be inclined.

[0090] The height of the straight opening 263 on one side is flush with the height of the inner top of the corresponding groove 28;

[0091] When the connecting rod 24 resets along the groove 28 of the vertical limiting guide rail 27 in the direction of the straight opening 263 after the pushing is completed, the inner top of the groove 28 is flush with the height of the upper edge of the straight opening 263, forming a smooth transition path without steps and gaps, and when the top of the connecting rod 24 slides in the groove 28 to the straight opening 263, it will not be jammed or blocked due to the height difference, and it will not appear to be tilted upward or fall downward, ensuring that the connecting rod 24 smoothly enters the inside of the adjusting box 260, and ensuring the smoothness of the resetting action.

[0092] The adjusting box 260 is arranged above the receiving platform 21, and the vertical limiting guide rail 27 is arranged on one side of the adjusting box 260. In order to stably install these structures, four support rods 29 are arranged in a rectangular array on both sides of the receiving platform 21;

[0093] The adjusting box 260 is installed at the top of the two support rods 29 upstream along the gypsum board conveying direction, and a cross rod 30 is installed at the top of the two support rods 29 downstream along the gypsum board conveying direction, and the end of each vertical limiting guide rail 27 away from the adjusting box 260 is connected to the bottom of the cross rod 30.

[0094] The gypsum board is conveyed from the upstream of the receiving platform 21 to the receiving platform 21 from the inlet of the receiving platform 21, and the receiving platform 21 only plays a receiving role, and the entire process is stationary, and only relies on the conveying equipment upstream of the receiving platform 21 to convey the gypsum board to the receiving platform 21, and then the movement of the gypsum board on the receiving platform 21 relies entirely on the pushing of the push plate 23, and the cutting position is arranged downstream of the receiving platform 21, and the push plate 23 pushes the gypsum board to the cutting position from the side of the gypsum board away from the cutting position, therefore, the position of the push plate 23 is reset is on the side of the receiving platform 21 away from the cutting position, and the adjusting box 260 is arranged at the top of the two support rods 29 upstream, which is consistent with the reset position of the push plate 23, so as to facilitate the subsequent driving of the push plate 23 upward.

[0095] The vertical limiting guide rail 27 is connected to the adjusting box 260 at one end and connected to the bottom of the horizontal rod 30 at the other end, so as to ensure the stability of the installation position of the vertical limiting guide rail 27. The vertical limiting guide rail 27 penetrates through the whole pushing plate 23 to push the gypsum board to move and cut, so as to facilitate the vertical limiting of the connecting rod 24 and the pushing plate 23 during the pushing of the gypsum board by the pushing plate 23.

[0096] The two supporting rods 29 on one side of the upstream of the gypsum board conveying direction are connected with a front extension bracket 31. A mounting base is fixedly arranged at the top of the front extension bracket 31. The mounting base is used for fixing a linear reciprocating power device. The driving cylinder 253 is fixedly installed on the mounting base. The position of the driving cylinder 253 is on the axis of the receiving platform 21, so as to facilitate the uniform force on all pushing plates 23.

[0097] In use, the gypsum board is conveyed to the receiving platform 21 by the conveying equipment upstream of the receiving platform 21. The centering and pushing device 22 on both sides of the receiving platform 21 pushes the gypsum board to the middle area of the receiving platform 21.

[0098] The driving cylinder 253 is started. The driving cylinder 253 drives all the pushing plates 23 to move forward. The pushing plate 23 pushes the gypsum board to the cutting position until the whole gypsum board is cut. The driving cylinder 253 drives all the pushing plates 23 to reset.

[0099] The driving motor 265 is started. The driving motor 265 drives the driving gear 262 to rotate. The driving gear 262 drives all the connecting rods 24 and the pushing plates 23 to rise.

[0100] The next gypsum board enters the receiving platform. The centering and pushing device 22 pushes the next gypsum board on the receiving platform to the middle area. The driving motor 265 controls the driving gear 262 to rotate reversely. All the pushing plates 23 are lowered to the surface of the receiving platform 21. The driving cylinder 253 drives all the pushing plates 23 to move forward.

[0101] The above operation is repeated.
