[0022] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0023] like Figure 1-Figure 6 As shown, a fire door 32 automatic overlapping mechanism includes a frame 1, a workbench 3 is arranged on the frame 1, and a stamping mechanism 2 is arranged on one side of the workbench 3. The stamping mechanism 2 is a prior art and will not be described here. The workbench 3 is connected to the assembly line of the fire door 32. After the fire door 32 is hot-pressed by the hot press, it enters the workbench 3. The stamping mechanism 2 can stamp the overlapping of the fire door 32 to increase the firmness of the fire door. A support rod 4 is rotatably arranged on the workbench 3. The support rod 4 is arranged in a plurality of lateral directions. Under the rotation of the support plate, the fire door 32 can be driven to move horizontally on the workbench 3. A transmission mechanism 6 is also arranged on the workbench 3. The transmission mechanism 6 should be arranged in parallel with the support rod 4. When the fire door 32 is opposite to the stamping mechanism 2, the transmission mechanism 6 can drive the fire plate to move close to the stamping mechanism 2, and send the fire door 32 to the impact mechanism for stamping. In addition, a limit plate 5 is provided on the workbench 3, and the limit door can abut against the side wall of the fireproof board. When punching, the fireproof door 32 is limited to prevent the position of the fireproof door 32 from deviation during punching.
[0024] Among them, a mounting plate 12 is provided on the workbench 3, and the support rod 4 is rotatably arranged between the two mounting plates 12. A first driven wheel 13 is provided at one end of the support rod 4 extending out of the mounting plate 12, and a first motor 14 is provided on the frame 1. A first driving wheel 15 is provided on the output end of the first motor 14. The first driving wheel 15 is connected to a plurality of first driven wheels 13 through a transmission member 16. The transmission member 16 can be a chain, a transmission belt, etc. The first driving wheel 15 is driven to rotate by rotating the output shaft of the first motor 14, and the first driven wheels 13 on the plurality of support rods 4 are driven to rotate under the drive of the transmission member 16, thereby driving the plurality of support rods 4 to rotate, thereby realizing the movement of the fire door 32 under the drive of the support rod 4.
[0025] In detail, the transmission mechanism 6 includes a connection seat 8 disposed on the workbench 3, and a first transmission wheel 9 and a second transmission wheel 10 are rotatably disposed on both sides of the connection seat 8, and a conveyor belt 11 is disposed between the first transmission wheel 9 and the second transmission wheel 10. In more detail, a driving device 7 is disposed on the transmission mechanism 6, and the driving device 7 includes a transmission rod 19 disposed on the frame 1, and a second driven wheel 20 is disposed on the transmission rod 19, and a second motor 21 is disposed on the frame 1, and a second driving wheel 22 is disposed on the output end of the second motor 21. In addition, a third driven wheel 31 is also disposed on the workbench 3, and the second driving wheel 22 is connected to the third driven wheel 31 through a transmission member 16, and the third driven wheel 31 is connected to the second driven wheel 20 through the transmission member 16, and the first transmission wheel 9 is sleeved on the transmission rod 19. The second driving wheel 22 is driven to rotate by the second motor 21, and the second driven wheel 20 is driven to rotate under the rotation of the third driven wheel 31, and then the transmission rod 19 is driven to rotate. At this time, the first transmission wheel 9 on the transmission rod 19 rotates accordingly, so that the conveyor belt 11 between the first transmission wheel 9 and the second transmission wheel 10 moves, and finally, when the fire door 32 is relative to the stamping mechanism 2, the fire door 32 is driven to move in a direction close to the stamping mechanism 2.
[0026] In some embodiments, a cylinder 23 is also provided on the frame 1. The position of the cylinder 23 is opposite to the connecting seat 8. The cylinder 23 is located at the bottom of the connecting seat 8. The ejection end of the cylinder 23 is connected to the bottom of the connecting seat 8. When the fire door 32 is opposite to the stamping mechanism 2, the connecting seat 8 is ejected by the cylinder 23 and the conveyor belt 11 is ejected at the same time, so that the fire door 32 is away from the support rod 4, reducing the friction between the conveyor belt 11 and the support rod 4 when moving the fire door 32, thereby improving the transportation efficiency.
[0027] For example, a first lead screw 17 is provided on the frame 1 for longitudinal rotation, a mounting plate 12 is provided on the frame 1, the first lead screw 17 is provided between the two mounting plates 12, a guide rod 33 is provided between the mounting plates 12, the guide rods 33 are provided on both sides of the first lead screw 17, a slide 18 is provided on the first lead screw 17 and the guide rod 33 for sliding, the limit plate 5 is fixedly connected to the slide 18, and the first lead screw 17 is connected to a motor, the motor drives the first lead screw 17 to rotate, the slide rail 34 drives the limit plate 5 to move under the rotation of the first lead screw 17, and the guide rods 33 on both sides guide the slide 18. In addition, slide rails 34 are provided on the frame 1, two slide rails 34 are provided on both sides of the first lead screw 17, a slider is provided on the slide rail 34, the limit plate 5 is fixedly connected to the slider, and the limit plate 5 is further guided by the provided slide rails 34. When the fire door 32 moves close to the stamping mechanism 2, the limiting plate 5 is abutted against the side wall of the fire door 32. When stamping, the fire door 32 is limited to prevent the position of the fire door 32 from deviating during stamping.
[0028] In some embodiments, a blocking mechanism 24 is also rotatably provided on the tail end of the rack 1. The tail end of the rack 1 refers to the end of the workbench 3 where the stamping is completed. An infrared sensor is provided on the rack 1, and the infrared sensor is electrically connected to the blocking mechanism 24. When the fire door 32 moves to a position opposite to the stamping mechanism 2, the infrared sensor detects the fire door 32 and sends an electrical signal to rotate the blocking mechanism 24. The blocking mechanism 24 can abut against the fire door 32 to prevent the fire door 32 from continuing to move. After the stamping of the fire door 32 is completed, the blocking mechanism 24 is rotated to release the movement restriction of the fire door 32, so that the fire door 32 can move.
[0029] In detail, the blocking mechanism 24 includes a first mounting block 25 and a second mounting block 26 respectively arranged on the workbench 3, the first mounting block 25 is hinged with a connecting block 27, and the second mounting block 26 is provided with a pushing member 28. A baffle 29 is vertically arranged at one end of the connecting block 27, and a connecting shaft 30 is arranged at the other end. The connecting shaft 30 is connected to the ejection end of the pushing member 28. The pushing member 28 can be a cylinder 23, an electric push rod, etc. In the initial state, the baffle 29 should be parallel to the position of the fire door 32, and the pushing member 28 is in a tightened state. When blocking is required, the ejection end of the pushing member 28 is ejected, driving the connecting shaft 30 to be ejected, and at the same time, the connecting block 27 rotates around the first mounting block 25, driving the baffle 29 to rotate, so that the block is perpendicular to the position of the fire door 32, thereby achieving blocking of the protective door, making the position of the fire door 32 more accurate, which is convenient for accurate stamping of the overlap.
[0030] In addition, the workbench 3 is composed of a plurality of crisscrossed profiles, which increase the load-bearing capacity and facilitate the installation of various modules.
[0031] In some embodiments, a clamping member is also provided on the limit plate 5, and the clamping member includes two clamping plates vertically opposed to each other. A second lead screw is provided on the limit plate 5, and both ends of the second lead screw are threads that rotate in opposite directions. The second lead screw is connected to a motor, and the motor drives the lead screw to rotate. The two clamping plates are respectively arranged on both sides of the second lead screw through a transmission sleeve. The rotating lead screw can drive the two clamping plates to move closer to or away from each other. When the limit plate 5 abuts against the fire door, the two clamping plates are driven to approach each other by driving the motor to clamp the top and bottom of the fire door, thereby increasing the stability of the limit plate 5 when abutting against the fire door. At the same time, when the fire door is pressed and overlapped, the limit plate 5 that clamps the fire door can drive the fire door away from the stamping mechanism 2 together with the conveyor belt 11, thereby reducing the load pressure of the conveyor belt 11.
