A turnover mechanism and an electrically fused brick turning machine

Abstract

This invention discloses a flipping mechanism and an electrofused brick flipping machine, including a flipping wheel rotatably mounted on a frame. The flipping wheel has multiple flipping openings circumferentially arranged on its circumference. Each flipping opening has a receiving position and a discharging position during its rotation. A clamping component is provided within each flipping opening. As the flipping opening moves from the receiving position to the discharging position, the clamping component clamps and limits the electrofused brick carried within the flipping opening. By incorporating the clamping component, when the flipping opening is in the receiving position, the electrofused brick can smoothly enter the flipping opening. Then, as the flipping opening rotates with the flipping wheel from the receiving position to the discharging position, the clamping component maintains its grip on the electrofused brick carried within the flipping opening. This avoids the risk of the electrofused brick slipping from the side of the flipping opening due to a shift in the center of gravity during flipping. Finally, the electrofused brick smoothly exits the flipping opening at the discharging position, achieving a completely safe flipping process.

Description

Technical Field

[0001] This invention relates to the field of dough turning machine technology, specifically to a turning mechanism and an electrofused brick turning machine. Background Technology

[0002] Electrofused zirconia-corundum bricks are white solids formed by melting pure alumina powder and zircon sand containing approximately 65% ​​zirconium oxide and 34% silica in an electric furnace, then pouring the mixture into a mold and cooling. Common rectangular slab-shaped electrofused bricks require flipping during processing, usually achieved using a flipping machine. Existing electrofused brick flipping machines generally meet daily usage needs, but some shortcomings still require improvement.

[0003] The applicant's earlier patent application, CN218143701U, published on December 27, 2022, disclosed a moving device for an electrofused brick turning machine. The technical solution includes: a main frame; a turning machine at the top of the main frame, guide rails symmetrically arranged on both sides of the turning machine, and a moving mechanism at the bottom of the main frame; the moving mechanism includes an adjusting frame, a fixed seat fixedly connected to one side of the adjusting frame, a threaded screw threadedly connected to the inner side of the fixed seat, a moving bracket at the bottom of the threaded screw, a cross arm symmetrically arranged on one side of the adjusting frame, and an auxiliary frame on one side of the cross arm. Its advantages are: the moving mechanism at the bottom of the main frame facilitates the movement of the main frame; the symmetrically movable cross arm on one side of the adjusting frame reciprocates, facilitating the cross arm's contact with the main frame at different distances; and the moving bracket, in conjunction with the auxiliary wheels, supports the movement of the main frame during movement, making it more flexible.

[0004] As mentioned in the aforementioned patent, existing dough-turning machines include a turning mechanism, which also comprises at least a conveying mechanism. According to existing technology, the actuating component of the turning mechanism is a rotating body that carries the fused bricks through a turning opening to perform a 180-degree turn. Conveying components are mounted on both sides of the turning mechanism. The width of the fused bricks on the conveying components is typically not less than the width of the conveying components, but greater than the width of the turning actuating component. Therefore, when the fused bricks are not centered on the conveying mechanism, during the process of being fed into the narrower turning opening and then carried through the turning opening for turning, there is a risk that the fused bricks may slip off the side of the turning opening due to a shift in the center of gravity. Therefore, there is an urgent need for a turning mechanism and a dough-turning machine for fused bricks to solve the above problems. Summary of the Invention

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0032] Please see Figure 1-8 The present invention provides a flipping mechanism, including a flipping wheel 2 rotatably mounted on a frame 1. The flipping wheel 2 has a plurality of flipping openings 3 circumferentially arranged on it. The flipping openings 3 have a receiving position and a discharging position during their rotational stroke as the flipping wheel 2 rotates. A clamping component is provided inside the flipping openings 3. When the flipping openings 3 move from the receiving position to the discharging position, the clamping component clamps and limits the electrofused bricks carried inside the flipping openings 3.

[0033] Specifically, there are preferably four flip ports 3, which are evenly distributed around the circumference of the flip wheel 2; the receiving position and the discharging position are on opposite sides of the flip wheel 2 at the same horizontal height; after the flip port 3 carries the electrofused brick at the receiving position, it moves to the discharging position in a direction of first upward and then downward rotation, and then the flip port 3 rotates from the discharging position to the receiving position in a direction of first downward and then upward, without carrying the electrofused brick; the flip wheel 2 can remain stationary when it moves the flip port 3 to the receiving position or the discharging position to facilitate the entry and exit of the electrofused brick; when the clamping assembly clamps the electrofused brick in the flip port 3, it can apply static friction to the surface of the electrofused brick to prevent the electrofused brick from slipping. In practical use, the rotating wheel 2 rotates, causing the rotating opening 3 to first be in the receiving position. Then, the electrofused brick can smoothly enter the rotating opening 3. Next, the rotating wheel 2 rotates, causing the rotating opening 3 carrying the electrofused brick to move from the receiving position to the discharging position. During this process, the clamping component keeps the electrofused brick in the rotating opening 3 clamped and limited, thereby avoiding the risk of the electrofused brick slipping off the side of the rotating opening 3 due to the shift of the center of gravity during the flipping process. Finally, the electrofused brick smoothly leaves the rotating opening 3 in the discharging position, and the flipping is completely safe.

[0034] Compared with the prior art, the flipping mechanism proposed in this embodiment of the invention, by setting a clamping component, allows the electrofused brick to smoothly enter the flipping opening 3 when it is in the receiving position. Then, the flipping opening 3 rotates with the flipping wheel 2 to move from the receiving position to the discharging position. During this process, the clamping component keeps clamping the electrofused brick carried in the flipping opening 3, thus avoiding the risk of the electrofused brick slipping off the side of the flipping opening 3 due to the shift of the center of gravity during the flipping process. Finally, the electrofused brick smoothly leaves the flipping opening 3 in the discharging position, achieving a completely safe flipping and improving the practicality of the device.

[0035] As a preferred technical solution of this embodiment, a first shaft cylinder 4 is fixedly installed on the frame 1, and the flipping wheel 2 is rotatably connected to the first shaft cylinder 4. Specifically, the first shaft cylinder 4 and the flipping wheel 2 are coaxially arranged, the first shaft cylinder 4 supports the flipping wheel 2, and the flipping wheel 2 rotates around the first shaft cylinder 4.

[0036] As a preferred technical solution of this embodiment, the clamping assembly includes a slide 5 movably disposed within the flip opening 3, a clamping rod 6 disposed on the slide 5, a drive plate 7 movably disposed within the flip wheel 2, a guide rod 8 elastically movably connected to the drive plate 7, one end of the guide rod 8 movably extending into the flip opening 3 and fixedly connected to the slide 5, the movement of the drive plate 7 being linked with the rotation of the flip wheel 2 through a linkage assembly. Specifically, the flip wheel 2 is provided with a first movable groove matching the drive plate 7, the guide rod 8 movably passes through the drive plate 7, and a retaining ring is provided at the end away from the slide 5, while a first spring 39 is sleeved at the end close to the slide 5, with both ends of the first spring 39 connected to the slide 5 and the drive plate 7 respectively; the inner wall of the flip opening 3 is provided with a through opening for the guide rod 8 and the first spring 39 to movably pass through; the surface of the clamping rod 6 is roughened. In actual use, the drive plate 7 moves and drives the slide 5 to move through the guide rod 8 and the first spring 39. The slide 5 drives the clamping rod 6 to move closer to the inner wall opposite to the flip opening 3. When there is an electrofused brick in the flip opening 3, the clamping rod 6 can clamp the electrofused brick in cooperation with the inner wall of the flip opening 3, and the first spring 39 is compressed to maintain the clamping force.

[0037] As a preferred technical solution of this embodiment, the linkage component includes a first drive shaft 9 rotatably disposed inside the flipping wheel 2, a linkage chamber 10 disposed inside the flipping wheel 2, one end of the first shaft cylinder 4 extending into the linkage chamber 10 and coaxially fixedly connected to a first bevel gear 11, one end of the first drive shaft 9 coaxially fixedly connected to a second bevel gear 12 meshing with the first bevel gear 11, the other end of the first drive shaft 9 coaxially fixedly connected to a circular plate 13, an eccentric handle 14 fixedly disposed on the circular plate 13, a sliding sleeve 15 sleeved on the eccentric handle 14, and the sliding sleeve 15 fixedly connected to the drive plate 7 through a sliding rod 44. Specifically, the first drive shaft 9 preferably has four corresponding flipping openings 3, which are evenly distributed around the circumference. Correspondingly, the structures related to the first drive shaft 9 are also preferably four sets. The eccentric handle 14 is located on the end face of the circular plate 13 away from the first transmission shaft 9. The eccentric handle 14 rotates with the circular plate 13 and makes a circular motion. The sliding sleeve 15 and the sliding rod 44 slide only in the direction of movement of the drive plate 7. The circular motion of the eccentric handle 14 can drive the sliding rod 44 to slide back and forth through the sliding sleeve 15. The sliding rod 44 then drives the drive plate 7 to slide back and forth. That is, under the drive of the drive plate 7 and the guide rod 8, the slide block 5 can drive the clamping rod 6 to alternately move closer to the inner wall of the flip opening 3 and away from the inner wall of the flip opening 3. The circular motion is specifically configured such that when the flipping port 3 moves from the receiving position to the discharging position, the clamping rod 6 first approaches the relative inner wall of the flipping port 3 and then moves away from the relative inner wall of the flipping port 3. This process allows the electrofused brick carried by the flipping port 3 to be gradually clamped and then gradually released when it moves from the receiving position to the discharging position. This ensures that the electrofused brick is clamped during the flipping process to prevent it from slipping, and also allows the electrofused brick to be released in the flipping port 3 before and after the flipping process, making it easier for it to enter and exit.

[0038] In another embodiment of the present invention, the clamping rod 6 is rotatably mounted on the slide 5, and the slide 5 is provided with a detection component. A correction position is set on the trajectory of the flipping port 3 from the receiving position to the discharging position. When the flipping port 3 is in the correction position, the detection component drives the clamping rod 6 to correct the center of gravity of the electrofused brick to be centered in the flipping port 3 through rolling friction. Specifically, the correction position is located above the vertical middle position of the flipping wheel 2. The electrofused brick in the flipping port 3 in the correction position has completed a 90-degree flip. Its weight at this time mainly acts downward on the detection component. The detection component is used to detect the direction of the center of gravity offset of the electrofused brick, and then drives the clamping rod 6 to rotate to roll and rub against the opposite direction of the center of gravity offset to drive the electrofused brick to move laterally to achieve center of gravity correction.

[0039] As a preferred embodiment, the detection assembly includes two symmetrically arranged detection rods 16 movably connected to a slide block 5. A detection shaft 17 is rotatably disposed within the slide block 5, and the detection shaft 17 can also be axially movable. A trigger cylinder 18 is sleeved on the detection shaft 17, and the trigger cylinder 18 can only be axially movable within the slide block 5. A detection ring 19 is threaded onto the external thread of the trigger cylinder 18. Two symmetrical undulating rods 20 are movably disposed within the slide block 5. The detection rods 16 are fixedly connected to the undulating rods 20 via a connecting rod 21 that slides through the slide block 5. One end of the undulating rod 20 is close to the detection ring 19 and is connected to the detection ring 19. The outer wall of the ring 19 is movably connected. One end of the detection shaft 17 is coaxially fixedly connected to two opposing third bevel gears 22. One end of the clamping rod 6 is coaxially fixedly connected to a fourth bevel gear 23 disposed between the two third bevel gears 22. Specifically, the detection rod 16 is arranged parallel to the surface of the slide block 5. The two detection rods 16 are respectively close to the two opposing open sides of the flip-out port 3. The axial direction of the detection shaft 17 is perpendicularly intersecting the axial direction of the clamping rod 6. Two convex rings are spaced apart on the detection shaft 17, and the two convex rings clamp the trigger cylinder 18, so that the detection shaft 17 and the trigger cylinder 18 move axially synchronously. The slide block 5 is provided with a second movable groove for the movement of the trigger cylinder 18, the detection ring 19, the undulating rod 20 and other related structures. Two more sets of convex rings are provided at both ends of the trigger cylinder 18. The two convex rings are movably connected to a first guide post fixed in the second movable groove, which restricts the rotation of the trigger cylinder 18, thereby allowing the rotation of the detection ring 19 to have a threaded feed action with the trigger cylinder 18. A lever 40 is fixedly installed at the end of the undulating rod 20 near the detection ring 19. Two opposing dial rings 41, matching the lever 40, are fixedly installed on the outer wall of the detection ring 19. A second guide post is fixedly installed in the second movable groove, sliding vertically through the undulating rod 20. A second spring 42 is sleeved on the end of the second guide post away from the detection rod 16. The movement of the undulating rod 20 in the second movable groove can drive the detection ring 19 to rotate through the lever 40 and the dial rings 41. The two undulating rods 20 on both sides move in opposite directions, corresponding to the up-and-down movement of the two detection rods 16 as the center of gravity of the electrofused brick shifts. The second spring 42 can hinder the movement of the undulating rod 20, that is, prevent the two detection rods 16 from having an undulation difference. After the center of gravity of the electrofused brick is corrected, the second spring 42 promotes the balanced support of the two detection rods 16 for the electrofused brick. Furthermore, after the detection ring 19 rotates relative to the trigger cylinder 18, it synchronously generates a threaded feed action, causing the trigger cylinder 18 to move axially. The trigger cylinder 18 then drives the detection shaft 17 to move axially, which in turn drives one of the third bevel gears 22 to mesh with the fourth bevel gear 23. Thus, the rotation of the detection shaft 17 is transmitted to the clamping rod 6, which then generates rolling friction on the surface of the clamped electrofused brick. The two third bevel gears 22 independently mesh with the fourth bevel gear 23, and with the rotation direction of the detection shaft 17 fixed, the two opposing third bevel gears 22 mesh with the fourth bevel gear 23 in opposite directions.

[0040] Furthermore, the specific transmission direction of the switching shaft 33 to the clamping rod 6 is set as follows: when the center of gravity of the electrofused brick shifts, causing the relative height of one side of the detection rod 16 on the slide 5 to decrease, the detection shaft 17 is driven to move axially through the above-mentioned principle process, so that one of the third bevel gears 22 and the fourth bevel gear 23 mesh and transmit the transmission. Then, the rotation of the detection shaft 17 can be transmitted to the clamping rod 6. The clamping rod 6 then applies lateral friction to the surface of the electrofused brick in the direction away from the detection rod 16 whose height has decreased, so that the center of gravity of the electrofused brick can be moved away from the detection rod 16 whose height has decreased, that is, the center of gravity of the electrofused brick is corrected. After the center of gravity of the electrofused brick is corrected, the two detection rods 16 no longer have a difference in undulation, so the axial movement of the detection shaft 17 will not be caused, so that the detection shaft 17 and the clamping rod 6 transmit the transmission, thus keeping the clamping rod 6 holding the electrofused brick stationary.

[0041] As a preferred embodiment, a drive shaft 24, coaxially movably penetrating the first shaft cylinder 4, is rotatably disposed within the tilting wheel 2. One end of the drive shaft 24 extends into the linkage chamber 10 and is coaxially fixedly connected to a fifth bevel gear 25. A second transmission shaft 26 is rotatably disposed within the tilting wheel 2. One end of the second transmission shaft 26 is coaxially fixedly connected to a sixth bevel gear 27 that meshes with the fifth bevel gear 25, and the other end is linked to the detection shaft 17 via a synchronous transmission assembly. Specifically, a servo motor is fixedly installed at the end of the first shaft cylinder 4 outside the tilting wheel 2. The output end of the servo motor is coaxially and fixedly connected to the drive shaft 24. When the flipping port 3 is in the correction position, the flipping wheel 2 is stationary, and the drive shaft 24 drives the fifth bevel gear 25 to rotate. The fifth bevel gear 25 drives the second transmission shaft 26 to rotate through the sixth bevel gear 27. The second transmission shaft 26 then drives the detection shaft 17 to rotate through the synchronous transmission assembly. Thus, when the center of gravity of the electrofused brick shifts, through the above principle process, when the detection shaft 17 is linked with the clamping rod 6, the rotating detection shaft 17 can drive the clamping rod 6 to rotate.

[0042] As a further preferred technical solution of this embodiment, the synchronous transmission assembly includes a first synchronous wheel 28 coaxially fixedly connected to the second transmission shaft 26, a second synchronous wheel 29 synchronously rotatably connected to the detection shaft 17, and a synchronous belt 30 connecting the first synchronous wheel 28 and the second synchronous wheel 29. A sliding key 31 is provided on the inner wall of the second synchronous wheel 29, and a keyway 32 matching the sliding key 31 is provided on the detection shaft 17. Specifically, the detection shaft 17 can move synchronously with the slide block 5 and can also move axially during the detection process. Therefore, the detection shaft 17 and the second synchronous wheel 29 are connected by the sliding key 31 and the keyway 32, ensuring both the rotational transmission of the detection shaft 17 and the second transmission shaft 26 and not affecting the axial movement of the detection shaft 17. Furthermore, the first synchronous wheel 28 is positioned away from the circular plate 13.

[0043] In another embodiment of the present invention, a switching shaft 33 is movably disposed at the end of the tilting wheel 2 away from the first shaft cylinder 4. A telescopic drive unit 34 for driving the switching shaft 33 to move axially is disposed inside the tilting wheel 2. One end of the switching shaft 33 extends into the linkage chamber 10 and is coaxially fixedly connected to a first damping plate 35. The first damping plate 35 is movably connected into the linkage chamber 10. The end of the drive shaft 24 extending into the linkage chamber 10 is coaxially fixedly connected to a second damping plate 36. The other end of the switching shaft 33 is coaxially fixedly connected to a third damping plate 37. A fourth damping plate 38 is fixedly disposed on the frame 1. Specifically, the switching shaft 33 and the drive shaft 24... The telescopic drive unit 34 is coaxially arranged; the telescopic direction of the telescopic drive unit 34 is parallel to the axis of the switching shaft 33; the switching shaft 33 rotates together with the tilting wheel 2; when the first damping plate 35 is in contact with the second damping plate 36, the third damping plate 37 and the fourth damping plate 38 remain separate, and vice versa; when the first damping plate 35 and the second damping plate 36 are in contact, the switching shaft 33 can rotate with the drive shaft 24, at which time the drive shaft 24 can drive the tilting wheel 2 to rotate as a whole; when the third damping plate 37 and the fourth damping plate 38 are in contact, the switching shaft 33 is relatively fixed to the frame 1, so the tilting wheel 2 is stationary, and at this time the drive shaft 24 can directly drive the second transmission shaft 26.

[0044] An electrofused brick turning machine includes the aforementioned turning mechanism and a conveying mechanism for feeding electrofused bricks into the turning port 3 at the receiving position and for carrying out the electrofused bricks from the turning port 3 at the discharging position. Specifically, the conveying mechanism includes pulley tracks 43 arranged side by side on opposite sides of the turning wheel 2.

[0045] Working principle: First, the tilting wheel 2 is stationary, and one tilting port 3 corresponds to the receiving position. Then, the electrofused brick is conveyed on the conveying mechanism to approach this tilting port 3. After the electrofused brick enters this tilting port 3, under the drive of the telescopic drive unit 34, the switching shaft 33 drives the first damping plate 35 to fit with the second damping plate 36. Then, the servo motor starts and drives the drive shaft 24 to rotate. The drive shaft 24 can drive the tilting wheel 2 to rotate through the linkage switching shaft 33. At this time, the tilting wheel 2 drives the tilting port 3 carrying the electrofused brick to move from the receiving position to the correction position; then the tilting wheel 2 drives the contents of the linkage chamber 10 to move. The second bevel gear 12 rotates around the fixed first bevel gear 11. The second bevel gear 12 then drives the circular plate 13 to rotate through the first transmission shaft 9. The circular plate 13 drives the eccentric handle 14 to move in a circular motion. The eccentric handle 14 drives the drive plate 7 to move closer to the flipping opening 3 through the sliding sleeve 15 and the slide rod 44. Then the drive plate 7 drives the slide 5 to move through the guide rod 8, so that the clamping rod 6 on the slide 5 moves closer to the electrofused brick and gradually clamps the electrofused brick in cooperation with the inner wall of the flipping opening 3. Under the action of the first spring 39, a suitable clamping force is applied, thereby preventing the electrofused brick from slipping sideways during this process.

[0046] Next, when the flipping port 3 moves to the correction position, the electrofused brick has flipped 90 degrees. Its gravity mainly acts on the two detection rods 16. When the electrofused brick has a center of gravity shift, one detection rod 16 moves down and the other detection rod 16 moves up. As a result, the two undulating rods 20 move relative to each other, and through the lever 40 and the dial ring 41, they drive the detection ring 19 to rotate. The detection ring 19 can then rotate relative to the trigger cylinder 18, synchronously generating a threaded feed action that drives the trigger cylinder 18 to move axially. This causes the trigger cylinder 18 to drive the detection shaft 17 to move axially. The detection shaft 17 can then drive one of the third bevel gears 22 and the fourth bevel gear 23 to mesh. At this time, the telescopic drive unit 34 drives the switching shaft 33 to move axially, causing the third damping plate 37 to move axially. When in contact with the fourth damping plate 38, the flipping wheel 2 remains stationary. The servo motor drives the fifth bevel gear 25 to rotate via the drive shaft 24. The fifth bevel gear 25 drives the detection shaft 17 to rotate via the sixth bevel gear 27, the second transmission shaft 26, the first synchronous pulley 28, the synchronous belt 30, and the second synchronous pulley 29 in sequence. Then, the detection shaft 17 transmits the rotation to the clamping rod 6, causing the clamping rod 6 to generate a frictional driving force on the electrofused brick in the opposite direction to the center of gravity offset. This drives the center of gravity of the electrofused brick to move towards the middle of the flipping opening 3 for correction. After the center of gravity of the electrofused brick is corrected, the two detection rods 16 no longer have a fluctuation difference, so there will be no axial movement of the detection shaft 17. That is, the detection shaft 17 and the clamping rod 6 stop transmission, thus keeping the clamping rod 6 holding the electrofused brick stationary.

[0047] Next, the flipping port 3 carries the corrected electrofused brick from the correction position to the discharge position. At this time, according to the same transmission process described above, the slide 5 can drive the clamping rod 6 to gradually loosen the electrofused brick. When the flipping port 3 moves to the discharge position, the electrofused brick is completely relaxed and returns to the conveying mechanism. The flipping wheel 2 stops again, and the conveying mechanism can take away the flipped and correctly centered electrofused brick.

[0048] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
