Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-6 As shown, this embodiment provides a concrete block flipping device, including: a housing 1.

[0029] like Figure 1-6As shown, the top of the outer casing 1 in this embodiment has a top groove 102, and a first screw 101 is provided at the top of the top groove 102. A screw motor 107 is provided at one end of the first screw 101. A first ring 2 is provided inside the outer casing 1. A slide block 201 is fixedly connected to the top of the first ring 2. A second ring 3 is provided inside the first ring 2. A clamping seat 303 is provided inside the second ring 3. A slider 304 is provided inside the clamping seat 303. A clamping plate 305 is provided at the front end of the slider 304. Conveyor belts 5 extend outward from both ends of the outer casing 1. The outer casing 1 is a horizontally placed cylinder with openings at both ends that extend into the conveyor belts 5. One conveyor belt 5 transports the blocks into the outer casing 1, and the other conveyor belt 5 outputs the rotated blocks. Inside the outer casing 1, the slide block 201 is secured by the top groove 102, lifting the first ring 2. The screw motor 107 drives the first screw 101 to rotate, and the threaded part of the screw and the threaded hole on the slide block 201 engages, thereby pushing the first ring 2 to move inside the outer casing 1, and transferring the block between the conveyor belts 5. The first ring 2 is fitted with a second ring 3. The clamping seat 303 on the second ring 3 is provided in two symmetrical positions. The slider 304 on the second ring 3 moves within the clamping seat 303, and the front clamping plate 306 clamps the block on the conveyor belt 5. Then the first ring 2 moves forward, and the second ring 3 rotates 180 degrees to complete the flipping of the block. The flipped block is then placed on the front conveyor belt 5 and transported out.

[0030] like Figure 1-6 As shown, in this embodiment, a second screw 103 is provided at the top of the first screw 101, a connecting sleeve 104 is provided on the front of the slide 201, an inner threaded sleeve 105 is provided inside the connecting sleeve 104 on the surface of the second screw 103, a rotating rod 203 is installed through the bottom of the slide 201, and a toothed sleeve 204 is sleeved on the rotating rod 203 on the surface of the slide 201 and inside the slide 201. The rotating rod 203 and the inner threaded sleeve 105 are connected by a connecting belt 106, and a toothed ring 302 is fixedly connected to the outside of the second ring 3. The second screw 103 does not rotate, and the connecting sleeve 104 is installed at the front end of the slide 201 and moves with the slide 201, simultaneously pushing the inner threaded sleeve 105 sleeved on the second screw 103 to move. The inner threaded sleeve 105 is installed inside the connecting sleeve 104 to prevent it from falling off. Its internal thread engages with the thread on the second screw 103, and thus rotates on the second screw 103 by the push of the connecting sleeve 104. It also drives the rotating rod 203 below to rotate via the connecting belt 106. The rotating rod 203 is embedded at the connection between the slide 201 and the first ring 2 and is fixed by a bearing to rotate. The entire second ring 3 is embedded in the first ring 2. A toothed ring 302 is provided on the outer ring and engages with the toothed sleeve 204. The toothed sleeve 204 is sleeved on the rotating rod 203. By driving the toothed sleeve 204 to rotate, the entire second ring 3 is driven to rotate, thereby realizing the rotation of the clamping structure on the second ring 3 and achieving the flipping effect.

[0031] like Figure 1-4 As shown, in this embodiment, a spring post 307 is fixedly connected inside the clamping base 303. A spring 306 is sleeved on the surface of the spring post 307 on one side of the slider 304. Limiting rods 308 are fixedly connected to both ends of the slider 304. Pull plates 4 are provided on both sides of the outer shell 1. A connecting rod 401 is fixedly connected to the pull plate 4 facing the outer shell 1. A hook 402 is fixedly connected to one end of the connecting rod 401. An output shaft 404 is installed through the center of the pull plate 4. A clamping motor 403 is provided at one end of the output shaft 404. The slider 304 has a hole in the center and passes through the spring post 307. The spring 306 at the end pushes the slider 304 to move towards the center, thereby moving it onto the clamping base 303 which is symmetrically positioned on both sides. The front clamping plate 305 is used to clamp and fix the block. The connecting rod 401 on the pull plate 4 passes through the outer shell 1. It is symmetrical on the front and back sides of the outer shell 1, with a total of four connecting rods 401. They are all facing outwards compared to the first ring 2 to prevent the connecting rod 401 from colliding with the first ring 2. When the clamping seat 303 rotates to the return position, the limiting rods 308 at both ends of the slider 304 are just locked into the hook 402. The clamping motor 403 controls the output shaft 404 to retract and pull the pull plate 4 and the connecting rod 401, which in turn pulls the limiting rod 308 through the hook 402, causing the slider 304 to compress the back spring 306 and move to both sides. The clamping plate releases the block and puts it down, completing the clamping action.

[0032] like Figure 1 , 2 As shown, the second ring 3 in this embodiment has sliding grooves 301 on both its front and back sides, and the first ring 2 is vertically installed with anti-detachment pins 202 inside the sliding grooves 301. The anti-detachment pins 202 on both sides of the first ring 2 are inserted into the sliding grooves 301 for fixation, thereby limiting and fixing the second ring 3. When the second ring 3 rotates, the anti-detachment pins 202 of the sliding groove 301 are always inside the sliding grooves 301 and do not affect the rotation of the second ring 3.

[0033] like Figure 5 As shown, in this embodiment, the second screw 103 is only provided with threads in the middle part; wherein, the length of the threads is adjusted so that the second ring 3 can rotate exactly 180 degrees, the clamping seats 303 at both ends exchange positions, and the thread is positioned in the horizontal direction between the two conveyor belts 5, so that the second ring 3 will not rotate before it is completely separated from the conveyor belt 5, preventing the brick from rotating prematurely and colliding with the conveyor belt 5.

[0034] like Figure 1-4As shown, in this embodiment, the hooks 402 have openings at both ends, and the two hooks 402 on the same side of the first ring 2 are in opposite directions. After the hooks 402 stop at the corresponding positions, the limiting rods 308 are inserted into the hooks 402 from the vertical direction of the movement of the connecting rods 401. The same applies to the hooks 402 at the two conveyor belts 5. At the same time, since the two clamping seats 303 move in opposite directions in the vertical direction when they rotate simultaneously when the blocks are flipped, the corresponding limiting rods 308 also disengage in opposite directions. Therefore, the hooks 402 on the same side need to be oriented in opposite directions to ensure that the two limiting rods 308 can disengage.

[0035] Working principle: The first ring 2 is located on the feeding conveyor belt 5. The limit rod 308 is pulled by the hook 402, and the clamping plate 305 is in the open state. The feeding conveyor belt 5 feeds the block into the clamping plate 305. The clamping motor 403 pushes the pull plate 4 through the output shaft 404. The connecting rod 401 drives the hook 402 to move towards the center of the outer shell 1. The spring 306 releases its elastic force to push the slider 304 until the clamping plate 305 clamps and fixes the block. At this time, the screw motor 107 starts and drives the slider 304 to move in the top groove 102. The first ring 2 moves forward and then connects to the sleeve 104. The inner threaded sleeve 105 and the second screw 103 rotate in contact with the threads, and the connecting belt 106 drives the rotating rod 203 to rotate. Finally, the toothed sleeve 204 rotates and meshes with the toothed ring 302 on the second ring 3, allowing the second ring 3 to rotate 180 degrees inside the first ring 2, realizing the flipping of the block. The first ring 2 moves the block to the discharge conveyor belt 5. At the same time, the limiting rod 308 at the other end of the slider 304 is inserted into the hook 402. The pull plate 4 pulls the hook 402 again to release the clamp 305, allowing the brick to fall onto the conveyor belt 5 and be transported out.
