Description

Technical Field

[0001] The invention relates to an automatic turning and double-sided grinding system for heavy bricks, belonging to the field of turning devices. Background Art

[0002] Bricks made of carbon products, zirconium materials, alumina materials, silicon materials, and refractory materials are often uneven on the upper and lower surfaces of each brick due to their production process and because the products are cut from the side. Therefore, the upper and lower surfaces of the bricks need to be polished before they are sold. For example, the column-type multifunctional machine tool with patent application number 202022822984.5 applied for by Zibo Boshan Yongli Industry and Trade Co., Ltd. is used to grind this type of hard refractory bricks. These bricks are often large, and the weight of a single brick is generally more than 500 pounds. After the mobile transport trolley drives the heavy bricks through the grinding head and grinds the top surface, several staff members use iron chains to hang the bricks, and use a crane to hook the iron chain to lift it up, turn the brick over, and then move the transport trolley to the initial position, pass through the grinding head again, and grind the other side.

[0003] However, the flipping process is very slow, requires many steps, and is very inefficient, which often affects on-time delivery. At the same time, people cooperate with the overhead crane to flip bricks weighing more than 500 kilograms. If the flipping direction is unexpected, it will also cause personal accidents. Summary of the Invention

[0014] The heavy brick automatic flip double-sided grinding system has a "T"-shaped chute and a "T"-shaped slider. The "T"-shaped head of the slider is stuck in the chute and moves along the chute.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Compared to the prior art, the automatic flipping and double-sided grinding system for heavy bricks described in the present invention avoids the huge inertia of heavy bricks during rotation during the flipping process, and also prevents bricks from falling due to insufficient friction. After the bricks are removed from the transport cart by the guide device and fixed, the lifting and lowering device lifts the guide device, causing the guide device to drive the heavy brick to stand upright. The rotating device drives the center of the guide device to rotate, and the heavy brick is rotated 180 degrees by the center. This does not generate outward inertia and does not affect the friction between the guide device and the heavy brick. After the rotation, the lifting and lowering device flattens the guide device, and the guide device returns the brick to its original position on the transport cart, achieving safe flipping of the heavy brick. This prevents the bricks from being suspended by friction, and also prevents bricks from falling due to insufficient friction. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Example 1

[0040] like Figures 1 to 20As shown, the automatic flipping double-sided grinding system for heavy bricks described in the present invention includes a column grinding device, which includes a base 6, a top cover 2, and a guide column connected between the base 6 and the top cover 2. A workbench 3 that moves up and down along the guide column is provided on the guide column. A driving screw 4 provided on the top cover 2 drives the workbench 3 to move up and down. A grinding head 1 is provided on the workbench 3. The base 6 is provided with parallel tracks 7 and a driving screw 4 for a carrying trolley 5. The carrying trolley 5 travels on the tracks 7 and is driven by a moving screw 8. Proximity switches are provided at the starting and end ends of the tracks 7. The proximity switches define the starting and end points of the travel trajectory of the carrying trolley 5. In this embodiment, the carrying trolley 5 travels to the end when the edge of the carrying trolley 5 is 10 cm away from the end of the track 7. The carrying trolley 5 of the column grinding device is provided with evenly distributed depressions. In this embodiment, the number of depressions is set to 8.

[0041] A brick turning device is provided at the end of the running track of the carrying trolley 5. The brick turning device is provided with a rotating device 10. A clamping frame 9 is connected to the rotating shaft of the rotating device 10. The clamping frame 9 clamps the brick and stands up. It is driven by the rotating device 10 to rotate 180 degrees. The clamping frame 9 falls and places the brick on the carrying trolley 5. The carrying trolley 5 drives the brick to pass through the grinding equipment again to grind the other side of the brick.

[0042] The automatic flipping and double-sided grinding system for heavy bricks has a clamping frame 9 that is a "C"-shaped frame, including a base plate 11 and side panels A12 and B13 fixedly connected to the two ends of the base plate 11. A reinforcing plate 14 extends outward from the connection between the base plate 11 and the side panels A12 and B13, and reinforcing ribs 15 are provided between the reinforcing plate 14 and the side panels A12 and B13 to prevent the "C"-shaped frame from being deformed due to large force when supporting heavy bricks. A drive column 16 is connected to the base plate 11. One end of the drive column 16 is hinged to the top of the rotating shaft of the rotating device 10. A bearing 17 is installed at the end of the piston rod of the lifting and lowering hydraulic cylinder 34. The outer ring of the bearing 17 is fixedly connected to the piston rod, and the drive column 16 is fixedly connected to the inner ring of the bearing 17. The cylinder body of the lifting and lowering hydraulic cylinder 34 is hinged to the ground. T-slots are provided on the opposing sides of the side panels A12 and B13. The base plate 11 is provided with a through hole A18 near the side panel A12 and a through hole B19 near the side panel B13. Drive motors B20 and C21 are installed on the base plate 11. The rotating shafts of the drive motors B20 and C21 are coaxially connected to the lead screws B22 and C23, respectively. The lead screws B22 and C23 pass through the through holes A18 and B19, respectively, and are parallel to the side panels A12 and B13.

[0043] A receiving device is provided on the clamping frame. There are two sets of receiving devices, namely, receiving device A24 and receiving device B25, which are respectively provided on side plate A12 and side plate B13, and are mirror-imaged, receiving device A24 and receiving device B25 respectively.

[0044] The guiding device includes a connecting plate 26 and a guiding head 27. The connecting plate 26 is provided with a screw hole that cooperates with the screw. The guiding device A24 and the guiding device B25 cooperate with the screw B22 and the screw C23 respectively through the screw holes on the connecting plate 26, and are driven forward and backward by the drive motor B20 and the drive motor C21.

[0045] Connecting plate 26 is connected to four L-shaped connectors 27. Connecting plates 26 are comprised of vertical plates 29 and horizontal plates 30. Vertical plates 29 connect to connecting plates 26. The horizontal plates 30 are equipped with three support rollers 32. Two hydraulic lifting cylinders 28 are located on the top of the horizontal plates 30. These two hydraulic lifting cylinders 28 and the three rollers are spaced apart on the horizontal plates 30, with one hydraulic lifting cylinder 28 installed after each support roller 32, followed by another support roller 32. A lifting plate 31 is connected to the tops of the two hydraulic lifting cylinders 28. The bottom of the horizontal plates 30 is equipped with T-shaped blocks 36, which snap into the T-shaped slots on the side plates to keep the horizontal plates 30 parallel to the side plates.

[0046] After driving the transport trolley 5 to the end of the motion trajectory, the driving motor B20 pushes the guiding device A24 forward through the screw B22, and the guiding head 27 of the guiding device A24 is inserted into the recess of the transport trolley 5. The support roller 32 of the guiding head 27 is rolled and supported at the bottom of the recess. Then the lifting cylinder drives the lifting plate 31 to rise, and the lifting plates 31 of the four guiding heads 27 lift the heavy bricks. At this moment, the weight of the heavy bricks is pressed on the lifting plates 31. At this time, the support rollers 32 play a supporting role, which effectively prevents the deformation of the connecting head 27.

[0047] Then the driving motor B20 pulls the guiding device A24 backward through the screw B22. At this time, the roller switches and rolls between the depression of the carrying trolley 5 and the side plate A12 of the C-shaped frame. The side plate A12 of the C-shaped frame is supported by the lifting and lowering hydraulic cylinder 34. Therefore, after the guiding device A24 returns to its initial position, the weight of the heavy bricks is pressed on the lifting and lowering hydraulic cylinder 34.

[0048] Once a heavy brick enters the C-shaped frame, the lifting hydraulic cylinder 28 on the guide head 27 of the guide unit B25 lifts the lifting plate 31, which, together with the lifting plate 31 of the guide unit A24, clamps the heavy brick at the top and bottom. When handling the first brick of a particular type, the worker moves the brick positioning plate 33 on the lifting plate 31 to the side of the brick and locks it in place. This allows the C-shaped frame to hold the heavy brick in place after it is erected, preventing it from sliding down.

[0049] At the end of the transport trolley 5's trajectory is a brick-turning device equipped with a rotary motor. Specifically, the device uses the rotary motor as its base 6. To avoid transmission angle errors, the rotary motor utilizes a direct-drive servo motor. A gripping frame 9 is hinged to the motor's shaft. After gripping a brick via the guide assembly, the gripping frame 9 is lifted upright by a lifting hydraulic cylinder 34, rotating 90 degrees from horizontal to vertical. At this point, the heavy brick is clamped by the lifting plates 31 of guide assembly A 24 and guide assembly B 25, while also being held in place by the brick positioning plate 33. The rotary motor drives the C-shaped frame to rotate 180 degrees. The vertical brick is stably lifted and rotated due to the low torque, avoiding the problem of heavy bricks slipping due to insufficient friction caused by accelerated rotation when rotating directly from both ends. After rotating 180 degrees, the lifting hydraulic cylinder 34 drives the gripping frame 9 to drop, i.e., rotate 90 degrees in the opposite direction, changing from a vertical position to a horizontal position. At this point, the side plate A12 is on top and the side plate B13 is on the bottom. The piston rod of the lifting hydraulic cylinder 28 of the guide device A24 retracts, driving the lifting plate 31 upward and away from the brick. The guide device B25 is driven forward by the drive motor C21. The cross plate 30 of the guide device B25 extends into the recess of the transport trolley 5 and moves forward in the recess of the transport trolley 5 via rollers. After the brick returns to the lifted position, the piston rod of the lifting hydraulic cylinder 28 of the guide device B25 retracts, and the lifting plate 31 moves downward, placing the heavy brick back on the transport trolley 5. The drive motor C21 drives the guide device B25 back away from the transport trolley 5. The transport trolley 5 then drives the brick through the grinding equipment again to grind the other side of the brick, completing double-sided grinding.

[0050] When the next brick has its top surface ground and is carried to the destination by the transport trolley 5, the guide device B25, driven by the drive motor C21, extends the cross plate 30 into the groove of the transport trolley 5. The brick is lifted off the transport trolley 5 and then retracted into the C-shaped frame, following the same steps as above. The lifting hydraulic cylinder 34 then raises the gripping frame 9, rotating it 180 degrees in the opposite direction. The lifting hydraulic cylinder 34 lowers the gripping frame 9, returning it to its initial position, completing one cycle. This cycle repeats itself.

[0051] The heavy brick automatic flip double-sided grinding system, the lifting and lowering hydraulic cylinder 34 lifts and lowers the clamping frame 9, the rotary motor drives the clamping frame 9 to rotate, and the lifting and lowering hydraulic cylinder 34 lifts and lowers the clamping frame 9 within a range of 90 degrees.

[0052] The heavy brick automatic flipping double-sided grinding system is characterized in that the bottom of the lifting and lowering hydraulic cylinder 34 is hinged to the ground, the piston rod is hinged to the rotating sleeve, the rotating sleeve is a ball bearing 17, the inner ring of the bearing 17 is sleeved on the driving column 16, and the outer ring of the bearing 17 is hinged to the piston rod of the lifting and lowering hydraulic cylinder 34.

[0053] In the heavy brick automatic turning double-sided grinding system, the rotary motor is provided with an output shaft, and the top of the output shaft of the rotary motor is hinged to the bottom of the driving column 16.

[0054] The heavy brick automatic flipping double-sided grinding system is provided with a set of guiding devices on the side panel A12 and the side panel B13, namely the guiding device A24 and the guiding device B25. The guiding device A24 and the guiding device B25 are arranged opposite to each other. Two electric screws are provided on the bottom plate 11. The two electric screws pass through the through hole A18 and the through hole B19 to drive the guiding device A24 and the guiding device B25 to move respectively.

[0055] In the automatic flipping and double-sided grinding system for heavy bricks, the width of the guide head 27 and the spacing between adjacent guide heads 27 correspond to the depressions on the carrying trolley 5.

[0056] The automatic turning and double-sided grinding system for heavy bricks has a guide device provided with rollers and a slide block matched with a slide groove.

[0057] The heavy brick automatic turning double-sided grinding system has a chute that is a "T"-shaped groove 35 and a slider that is a "T"-shaped slider. The "T"-shaped head of the slider is stuck in the chute and moves along the chute.

[0058] The automatic flipping and double-sided grinding system for heavy bricks is such that the horizontal plate 30 gradually becomes thinner upwards toward the transport trolley 5, forming an upwardly inclined chamfer to prevent the front end of the horizontal plate 30 from being unable to be inserted into the depression of the transport trolley 5 after the clamping frame 9 undergoes micro-deformation, thereby forming a certain fault tolerance. As long as the front end of the horizontal plate 30 is inserted into the depression of the transport trolley 5, the transport trolley 5 begins to bear the load. The further the horizontal plate 30 moves forward, the load is gradually transferred to the transport trolley 5, and the deformation of the clamping frame will gradually become smaller.
