Description

Technical Field

[0001] The invention relates to the technical field of conveying devices, in particular to a prefabricated board conveying device. Background Art

[0002] Prefabricated panels are the modules or panels used in engineering projects. They are called prefabricated panels because they are prefabricated concrete parts produced and processed in the prefabrication yard and transported directly to the construction site for installation. When making prefabricated panels, first use wooden boards to nail a hollow model. After the hollow part of the model is filled with steel bars, the hollow part is filled with cement. After it dries, the wooden boards are knocked off, and what remains is the prefabricated panel. Prefabricated panels have many uses in construction, such as the cement panels covering the ditches beside the highway and the cement panels used as insulation layers on the roof. Prefabricated panels need to be transported during production. Currently, the prefabricated panels are transported by placing them on conveyor belts.

[0003] However, during the current production of prefabricated panels, the panels are fed into the mold through a placing machine, and the mold is transported to the vicinity of the stacking device for stacking through a conveyor belt. After drying, the demoulding prefabricated panels need to be transported to the designated area for stacking through a conveyor belt again. The conveyor belt is not equipped with a detection mechanism during transportation. When the prefabricated panels are produced and laid, the surfaces of the prefabricated panels are not vibrated horizontally. The dried prefabricated panels are directly transported to the finished product area for stacking through a conveyor belt without detection. The prefabricated panels with uneven surfaces are prone to uneven installation and large gaps in subsequent engineering construction, affecting the stability of the building structure. The prefabricated panels will shake during transportation, and some sand, gravel and cement will fall onto the surface of the conveyor belt during the shaking. There is no collection mechanism at the end of the conveyor belt, resulting in a messy ground and waste of sand and gravel. Summary of the invention

[0010] Specifically, the conveying mechanism includes two transmission rollers, which are connected to the bracket for relative rotation. Conveyor belts are provided on the two transmission rollers. A first motor is installed on the bracket. The output end of the first motor and the end of one of the transmission rollers are fixedly connected with a sprocket, and the two sprockets are driven by a chain.

[0011] Specifically, the conveying mechanism further includes a plurality of support plates, and a plurality of support plates that abut against the inner side of the conveyor belt are fixedly connected to the bracket at equal intervals.

[0012] Specifically, the flipping mechanism includes two fixed seats, fixed seats are relatively fixedly connected on both sides of the bracket, screws are threadedly connected to the two fixed seats, side plates are rotatably connected to the two groups of screws, and a rotating shaft is rotatably connected between the two side plates.

[0015] The beneficial effects of the present invention are:

[0016] (1) The present invention relates to a prefabricated board conveying device, wherein two sets of detection mechanisms are provided on the bracket. After the prefabricated board is placed on the conveyor belt, it passes through one of the detection mechanisms. At this time, the surface of the prefabricated board will collide with the ball bearing at the bottom of the adjusting rod. The distance between the ball bearing and the conveyor belt is the qualified thickness of the prefabricated board. If the prefabricated board is not level, it will be uneven. After the prefabricated board passes the bottom of the ball bearing, if a certain position of the prefabricated board is higher, it will drive the push rod to rise. When the push rod rises, it drives the battery to rise, thereby achieving the collision between the lower contact plate and the upper contact plate at the bottom of the alarm light. The circuit is connected at this time, and the corresponding alarm light will also light up to remind the staff that the prefabricated board is unqualified. If the error of the prefabricated board is large, the push rod will continue to rise, and the alarm light will also be pushed up. The second spring can protect the alarm light to prevent the push rod from damaging it.

[0017] (2) The precast board conveying device described in the present invention has a flipping mechanism located between two detection mechanisms on the bracket. When one side of the precast board is detected and passes through the flipping mechanism, the bidirectional synchronous cylinder can clamp the precast board, and the second motor drives the bidirectional synchronous cylinder to rotate 180 degrees, thereby realizing the flipping of the precast board, making it easier for another detection mechanism to detect the other side of the precast board, realizing two-sided detection, and avoiding unstable installation and excessive gaps caused by uneven surfaces of the precast board during construction.

[0018] (3) In the prefabricated board conveying device described in the present invention, marking mechanisms are installed on both sets of detection mechanisms. When the prefabricated board is qualified in the detection, the push rod will maintain a position and will not rise. When the surface of the prefabricated board is unqualified and there is a protrusion, the push rod will be pushed to rise. At this time, the alarm light is connected and illuminated to alarm. At the same time, as the push rod rises, the pull rod is driven to rise. Since the self-spray paint can is fixed to the mounting ring, when the pull rod rises, it will collide with the nozzle at the end of the self-spray paint can, and the paint inside the self-spray paint can will be sprayed to the unqualified position of the prefabricated board, which is convenient for later repairs.

[0019] (4) The precast board conveying device described in the present invention has a recovery mechanism on the bracket. When the precast boards are transported on the conveyor belt, sand and gravel will fall from one end of the conveyor belt into the inside of the collecting bucket, and finally be transported from the conveyor belt to the end of the entire device, thereby realizing the recycling of sand and gravel and avoiding waste.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0033] Among them, the drawings are only used for illustrative explanations, and they only represent schematic diagrams rather than actual pictures, and should not be understood as limitations on the present invention. In order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of actual products. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0034] like Figure 1-Figure 10 As shown, a prefabricated board conveying device according to the present invention comprises a bracket 1, a conveying mechanism 2 installed on the bracket 1, two detection mechanisms 4 are relatively installed on the bracket 1, and a marking mechanism 6 is installed on both of the two detection mechanisms 4, a turning mechanism 3 located between the two detection mechanisms 4 is installed on the conveying mechanism 2, and a recovery mechanism 5 is installed on the bracket 1, and the recovery mechanism 5 is connected to the conveying mechanism 2;

[0035] The detection mechanism 4 includes two top frames 401, and two top frames 401 with inverted cross-section structures are relatively fixedly connected to the bracket 1. Push rods 402 are equidistantly slidably connected to the two top frames 401. The two groups of push rods 402 are fixedly connected to limit plates 403 located at the bottom of the top frames 401. A first spring 404 is clamped between the limit plates 403 and the top frames 401. A battery 405 is installed inside the push rods 402. A sealing plate 406 is threadedly connected to the push rods 402. The sealing plate 406 conflicts with the battery 405. The sealing plate 406 is provided with two A lower abutment plate 411, two support rods 407 are symmetrically fixedly connected to the two top frames 401 about the multiple push rods 402, and an alarm light 408 is fixedly connected to the two support rods 407 on both sides of the push rods 402. An upper abutment plate 412 is provided at the bottom of the alarm light 408, and the upper abutment plate 412 is arranged corresponding to the lower abutment plate 411. A second spring 413 is clamped between the support rods 407 and the alarm light 408. The bottoms of the two groups of push rods 402 are threadedly connected to adjusting rods 409, and the bottoms of the two groups of adjusting rods 409 are rotatably connected to balls 410;

[0036] The conveying mechanism 2 includes two transmission rollers 205, the bracket 1 is connected to the two transmission rollers 205 for relative rotation, the two transmission rollers 205 are provided with a conveyor belt 201, the bracket 1 is installed with a first motor 202, the output end of the first motor 202 and the end of one of the transmission rollers 205 are fixedly connected with a sprocket 204, the two sprockets 204 are driven by a chain 203, and the bracket 1 is fixedly connected with a plurality of support plates 206 that are in contact with the inner side of the conveyor belt 201 at equal intervals;

[0037] When producing prefabricated panels for some drainage ditches, the prefabricated panels after drying can be placed on the conveyor belt 201, and the first motor 202 can be started to realize the movement of the sprocket 204 and the chain 203, so as to further realize the rotation of the conveyor belt 201 to move the prefabricated panels toward the top frame 401. When the prefabricated panels pass through the ball 410 at the bottom of the adjusting rod 409, they roll with the ball 410, and the distance between the ball 410 and the conveyor belt 201 is the qualified thickness of the prefabricated panels. When the prefabricated panels are transported on the conveyor belt 201, the support plate 206 can support the prefabricated panels to avoid tilting. If the thickness of the prefabricated panels is qualified, the ball 410 will not be resisted upward, and the adjusting rod 409 will not drive the push rod 402 to rise, and the first spring 404 will not be compressed. If the surface of the prefabricated panels vibrates unevenly during the laying process, the surface of the prefabricated panels will be uneven, and the surface convexity of the prefabricated panels will be When the prefabricated board passes through the ball bearing 410 and encounters a high place, the ball bearing 410 will be lifted up, and the adjusting rod 409 will also drive the push rod 402 to move in the direction of the top frame 401, and the first spring 404 is compressed. The battery 405 located inside the push rod 402 will also rise with the sealing plate 406. When the surface of the prefabricated board exceeds the qualified thickness, the moving distance of the push rod 402 will become larger, and when the sealing plate 406 moves beyond the qualified range, the lower contact plate 411 will conflict with the upper contact plate 412. At this time, the circuit is connected, and the alarm light 408 flashes to remind the staff that the prefabricated board is unqualified. The distance between the ball bearing 410 and the conveyor belt 201 can be adjusted according to the thickness of the prefabricated board. When adjusting, you only need to rotate the adjusting rod 409 to realize its rise or fall on the push rod 402, so as to realize the detection of prefabricated boards of different thicknesses.

[0038] Specifically, Figure 6 , Fig. 9 and Fig.10 As shown, the marking mechanism 6 includes a fixing rod 601, and the sides of the two top frames 401 are fixedly connected with a plurality of fixing rods 601 corresponding to the push rods 402 at equal distances, and the bottoms of the plurality of fixing rods 601 are fixedly connected with mounting rings 604, and the interiors of the two groups of mounting rings 604 are plugged with self-spray paint cans 605, and the self-spray paint cans 605 and the mounting rings 604 are fixed by screws 607, and the sides of the plurality of push rods 402 are fixedly connected with pull rods 602, and the sides of the pull rods 602 are fixedly connected with a placement plate 603, and the end of the self-spray paint can 605 is in conflict with the placement plate 603, and the end of the self-spray paint can 605 is installed with a nozzle 606, and the nozzle 606 penetrates the placement plate 603;

[0039] No matter which side of the prefabricated board is being tested, as long as the thickness of the prefabricated board exceeds the qualified range, the push rod 402 will rise to cause the upper contact plate 412 to collide with the lower contact plate 411, and the alarm light 408 will flash. At the same time, as the push rod 402 rises, the pull rod 602 on one side will also rise. Since the fixed rod 601 is fixedly connected to the top frame 401, and the self-spray paint can 605 is fixed to the mounting ring 604 on one side of the fixed rod 601 by screws 607, when the pull rod 602 rises, it will also drive the placement plate 603 to rise. Since the placement plate 603 conflicts with the nozzle 606 at the bottom of the self-spray paint can 605, when the push rod 402 drives the pull rod 602 to rise, the placement plate 603 presses the nozzle 606, and the self-spray paint can 605 will spray colored gas onto the prefabricated board at this time, which is convenient for the staff to find the unqualified position for rework, and the nozzle 606 is located at the rear end of the ball 410, and the post-test painting is more conducive to the precise painting position.

[0040] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the flip mechanism 3 includes two fixed seats 301, the two sides of the bracket 1 are relatively fixedly connected with the fixed seats 301, the two fixed seats 301 are both threadedly connected with screws 302, the two groups of screws 302 are both rotatably connected with side plates 303, and the two side plates 303 are both rotatably connected with a rotating shaft 305, a second motor 304 is installed on the side wall of one of the side plates 303, the output end of the second motor 304 is fixedly connected to the rotating shaft 305, a two-way synchronous cylinder 306 is installed on the rotating shaft 305 located at the top of the conveyor belt 201, and clamps 307 are installed on both sides of the two-way synchronous cylinder 306, a baffle 308 located at the bottom of the clamp 307 and the outside of the two-way synchronous cylinder 306 is fixedly connected between the two side plates 303, and the cross section of the baffle 308 located at the top of the conveyor belt 201 is a U-shaped structure;

[0041] After the surface inspection of the prefabricated board is completed, it is continued to be transported through the conveyor belt 201. When the prefabricated board is transported to the position of the baffle plate 308, it is blocked by the baffle plate 308 and cannot move forward. At this time, the two-way synchronous cylinder 306 is started to realize the relative movement of the two clamping plates 307 to clamp the prefabricated board. The second motor 304 is further started to drive the rotating shaft 305 to rotate 180 degrees. At this time, the clamping plate 307 on one side of the two-way synchronous cylinder 306 will drive the prefabricated board to flip 180 degrees, that is, the bottom surface of the prefabricated board faces upward, completing the reversal of the prefabricated board. When the thickness of the prefabricated board changes, the screw 302 can be rotated to drive the side plate 303 to rise, which also changes the position of the clamping plate 307, which is convenient for more stable clamping of the prefabricated board. After the prefabricated board is flipped, it continues to be transported on the conveyor belt 201. When passing through another set of balls 410, if the prefabricated board is uneven, the push rod 402 will contact the connected circuit to alarm, completing the inspection of both sides, which is conducive to the stable construction during the later engineering construction, reducing the gap and improving the firmness of the structure.

[0042] Specifically, Figure 1 and Figure 2 As shown, the recycling mechanism 5 includes two driving shafts 501, and the two sides of the bracket 1 are connected to the two driving shafts 501 for relative rotation, and a conveyor belt 502 is connected between the two driving shafts 501, and the length of the conveyor belt 502 is greater than the length of the conveyor belt 201, and the side of the sprocket 204 and the end of one of the driving shafts 501 are fixedly connected with a belt reel 503, and a belt 504 is connected between the two belt reels 503, and a collecting bucket 505 located at the bottom of the conveyor belt 201 is installed on the bracket 1, and the bottom of the collecting bucket 505 is located at the top of the conveyor belt 502;

[0043] When the first motor 202 drives the sprocket 204 to rotate, the belt reel 503 cooperates with the belt 504 to drive the drive shaft 501 to rotate. Since the belt 504 on the belt reel 503 is in an ∞-shaped structure, the rotation direction of the drive shaft 501 is opposite to the rotation direction of the conveyor belt 201. Then, the sand and gravel detected to have fallen from the prefabricated board on the conveyor belt 201 will fall into the collecting bucket 505 and finally be transported from the conveyor belt 502 to the end of the entire device, so that the sand and gravel can be recycled again. On the one hand, it can avoid the adhesion of sand and gravel to the conveyor belt 201 and affect the placement of the prefabricated board, and on the other hand, it can avoid the waste of sand and gravel.

[0044] When the present invention is in use, first, when producing prefabricated panels for some drainage ditches, the prefabricated panels after drying can be placed on the conveyor belt 201, and the first motor 202 can be started to realize the movement of the sprocket 204 and the chain 203, so as to further realize the rotation of the conveyor belt 201 to move the prefabricated panels toward the top frame 401. When the prefabricated panels pass through the ball 410 at the bottom of the adjusting rod 409, they roll with the ball 410, and the distance between the ball 410 and the conveyor belt 201 is the qualified thickness of the prefabricated panels. When the prefabricated panels are transported on the conveyor belt 201, the support plate 206 can support the prefabricated panels to avoid tilting. If the thickness of the prefabricated panels is qualified, the ball 410 will not be resisted upward, and the adjusting rod 409 will not drive the push rod 402 to rise, and the first spring 404 will not be compressed. If the surface of the prefabricated panels vibrates unevenly during the laying of materials, the surface of the prefabricated panels will be uneven. The convex and concave surfaces of the prefabricated board exist relatively, so when the prefabricated board passes through the ball bearing 410 and encounters a high place, the ball bearing 410 will be lifted up, and then the adjusting rod 409 will also drive the push rod 402 to move in the direction of the top frame 401, the first spring 404 is compressed, and the battery 405 located inside the push rod 402 will also rise with the sealing plate 406. When the surface of the prefabricated board exceeds the qualified thickness, the moving distance of the push rod 402 will become larger, and when the sealing plate 406 moves beyond the qualified range, the lower contact plate 411 will conflict with the upper contact plate 412. At this time, the circuit is connected, and the alarm light 408 flashes to remind the staff that the prefabricated board is unqualified. The distance between the ball bearing 410 and the conveyor belt 201 can be adjusted according to the thickness of the prefabricated board. When adjusting, it is only necessary to rotate the adjusting rod 409 to realize its rise or fall on the push rod 402, so as to realize the detection of prefabricated boards of different thicknesses;

[0045] Then, after the surface inspection of the prefabricated board is completed, it is continuously transported by the conveyor belt 201. When the prefabricated board is transported to the position of the baffle plate 308, it is blocked by the baffle plate 308 and cannot move forward. At this time, the bidirectional synchronous cylinder 306 is started to realize the relative movement of the two clamping plates 307 to clamp the prefabricated board. The second motor 304 is further started to realize that it drives the rotating shaft 305 to rotate 180 degrees. At this time, the clamping plate 307 on one side of the bidirectional synchronous cylinder 306 will drive the prefabricated board to flip 180 degrees, that is, the bottom surface of the prefabricated board faces upward, completing the reversal of the prefabricated board. When the thickness of the prefabricated board changes, the screw 302 can be rotated to drive the side plate 303 to rise, which also changes the position of the clamping plate 307, which is convenient for more stable clamping of the prefabricated board. After the prefabricated board is flipped, it continues to be transported on the conveyor belt 201. When passing through another set of balls 410, if the prefabricated board is uneven, the push rod 402 will be pressed against the connected circuit to alarm, completing the inspection of both sides, which is conducive to the stable construction during the later engineering construction, reducing the gap and improving the firmness of the structure.

[0046] Next, no matter which side of the prefabricated board is tested, as long as the thickness of the prefabricated board exceeds the qualified range, the push rod 402 will rise to make the upper contact plate 412 collide with the lower contact plate 411, and the alarm light 408 will flash. At the same time, as the push rod 402 rises, the pull rod 602 on one side will also rise. Since the fixed rod 601 is fixedly connected to the top frame 401, and the self-spray paint can 605 is fixed to the mounting ring 604 on one side of the fixed rod 601 by screws 607 When the pull rod 602 rises, the placement plate 603 is also driven to rise. Since the placement plate 603 conflicts with the nozzle 606 at the bottom of the self-spray paint can 605, when the push rod 402 drives the pull rod 602 to rise, the placement plate 603 presses the nozzle 606. The self-spray paint can 605 will spray colored gas onto the prefabricated plate, which is convenient for the staff to find the unqualified position for rework. The nozzles 606 are all located at the rear end of the ball 410, and the spray paint after detection is more conducive to the precise spray paint position.

[0047] Finally, when the first motor 202 drives the sprocket 204 to rotate, the belt reel 503 cooperates with the belt 504 to drive the drive shaft 501 to rotate. Since the belt 504 on the belt reel 503 is in an ∞-shaped structure, the rotation direction of the drive shaft 501 is opposite to the rotation direction of the conveyor belt 201. Then, the sand and gravel detected to have fallen from the prefabricated board on the conveyor belt 201 will fall into the collecting bucket 505 and finally be transported from the conveyor belt 502 to the end of the entire device, so that the sand and gravel can be recycled again. On the one hand, it can avoid the adhesion of sand and gravel to the conveyor belt 201 and affect the placement of the prefabricated board, and on the other hand, it can avoid the waste of sand and gravel.
