[0033] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0034] Please see Figures 1 to 7The transformer core turning device and its operating method provided by the present invention will now be described. The transformer core turning device includes a base 1, an intermittent rotating support roller, a turning cylinder 2, and a conveying assembly. The base 1 is provided with an intermittent rotating support roller. The turning cylinder 2 is rotatably mounted on the intermittent rotating support roller. The inner cavity of the turning cylinder 2 has two vertically arranged partition walls 6, which divide the inner cavity of the turning cylinder 2 into four working areas. The two partition walls 6 in each working area are respectively provided with a feed inlet 3 and a discharge outlet 4 along the rotation direction of the turning cylinder 2. The conveying assembly includes a moving roller group 9, a linkage rack, and a drive gear 5. The moving roller group 9 is slidably mounted on the side wall of the partition wall 6 for carrying and conveying the core 7. A linkage rack is provided on one side of the moving roller group 9. The drive gear 5 is located on one side of the partition wall 6 and meshes with the linkage rack to drive the moving roller group 9 to move closer to or away from the feed inlet 3 or the discharge outlet 4.

[0035] Compared with the prior art, the transformer core flipping device provided by the present invention requires the core 7 to be flipped after being fixed by the frame. During the flipping process of the core 7, the flipping cylinder 2 is first rotated on the base 1 by means of the support roller. The interior of the flipping cylinder 2 is divided into four working areas by the partition wall 6. The four working areas, together with the intermittent rotating support roller, can achieve non-stop operation; that is, the core 7 is continuously put into the interior of the flipping cylinder 2 and the flipped core 7 is continuously taken out from the discharge port 4.

[0036] Firstly, each working area is equipped with a feed inlet 3 and a discharge outlet 4. When the iron core 7 needs to be flipped, the iron core 7 is first placed on the moving roller group 9 from the feed inlet 3, and the iron core 7 is moved to the inside of the working area by means of the linkage rack and drive gear 5 until one side of the iron core 7 is attached to the vertical partition wall 6 of the working area. As the intermittent rotating support roller rotates, the iron core 7 rotates 90° with the working area to complete the flipping action. The flipped iron core 7 is located on another moving roller group 9 in the working area and is driven by the moving roller group 9 to move towards the discharge outlet 4.

[0037] The transformer core flipping device provided by this invention, by setting a flipping cylinder 2 and a partition wall 6 inside the flipping cylinder 2, can drive the core 7 on one side of the partition wall 6 to flip simultaneously when the flipping cylinder 2 rotates, realizing the automated flipping of the core 7, reducing the number of manpower and labor intensity, and improving work efficiency; by setting intermittent rotating support rollers and flipping cylinder 2, and setting four working areas inside the flipping cylinder 2, the core 7 can be flipped continuously without stopping the machine or resetting the flipping cylinder 2, reducing reset time and downtime; further improving the working efficiency of core 7 flipping.

[0038] In some possible embodiments, please refer to Figure 1The partition wall 6 is a hollow structure; the inner cavities of the two partition walls 6 are interconnected, and a driving zone is formed at the connection between the inner cavities of the two partition walls 6. The moving roller group 9 and the linkage rack are located in the inner cavity of the partition wall 6, and the driving gear 5 is located in the driving zone. The driving zone has a driving motor that drives the driving gear 5; the end of the linkage rack extends into the driving zone to connect to the driving gear 5; the driving gear 5 drives the linkage rack to move toward the side of the discharge port 4.

[0039] Specifically, the partition wall 6 has a hollow structure, and its inner cavity is used to accommodate the transmission components and the drive gear 5. Since the two partition walls 6 are set vertically, the middle of the two partition walls 6 is connected, and the connected part forms a cuboid space. This space serves as the drive area, and its interior is used to install the drive motor, drive gear 5, etc.

[0040] The drive zone is provided with one or more drive gears 5. The drive gear 5 meshes with the linkage rack, drives the linkage rack to move, and then drives the moving roller group 9 to move along the diameter direction of the flipping cylinder 2.

[0041] The drive motor can rotate bidirectionally or unidirectionally. When the drive motor rotates bidirectionally, the drive gear 5 is located on the output shaft of the drive motor. Driven by the drive motor, the drive gear 5 also moves bidirectionally, enabling the movement and reset of the moving roller group 9. For example, when the drive motor rotates in the forward direction, the drive gear 5 rotates in the forward direction, driving the moving roller group 9 to move towards the discharge port 4; when the drive motor rotates in the reverse direction, the drive gear 5 rotates in the reverse direction, driving the moving roller group 9 to move towards the feed port 3, thus resetting the moving roller group 9.

[0042] When the drive motor rotates in one direction, after the drive gear 5 drives the moving roller group 9 to move to the side of the discharge port 4, the drive gear 5 disengages from the linkage rack. A torsion spring can be installed on the moving roller group 9, and the torsion spring drives the moving roller group 9 and the linkage rack to move in opposite directions until the moving roller group 9 is reset.

[0043] In some possible embodiments, please refer to Figure 1 and Figure 5 The partition wall 6 has two moving roller groups 9 on the same side, and the two moving roller groups 9 are located in two different working areas respectively; the two moving roller groups 9 are connected by a linkage rod 8, which passes through the drive area and is used to pull the two moving roller groups 9 to move in the same direction; a linkage rack is provided on the linkage rod 8; the partition wall 6 has two moving roller groups 9 on both sides, and the two moving roller groups 9 are symmetrically arranged about the axis of the flipping cylinder 2.

[0044] Each of the two partition walls 6 has a conveying assembly within its inner cavity. The moving roller group 9 of the conveying assembly extends out of the side wall of the partition wall 6 via a moving slot formed on the partition wall 6. A linkage rack in the conveying assembly is located within the inner cavity of the partition wall 6 and connects the two moving roller groups 9 at both ends of the partition wall 6. The linkage rack passes through the drive area and meshes with the drive gear 5 of the drive area. Under the action of the linkage rack, the drive gear 5 can simultaneously drive the two moving roller groups 9 to move in the same direction. That is, it can simultaneously realize that one moving roller group 9 in two adjacent working areas moves from the feed inlet 3 towards the inside of the working area, and the other moving roller group 9 moves from the inside of another working area towards the discharge outlet 4.

[0045] The linkage rod 8 connects two moving roller groups 9 simultaneously, enabling the two working areas to operate at the same time, reducing the feeding and discharging time and improving work efficiency.

[0046] In some possible embodiments, please refer to Figure 1 and Figure 5 The partition wall 6 has a limiting block 10 in its inner cavity. The limiting block 10 is located on the side near the feed inlet 3. The limiting block 10 and the moving roller group 9 are located on the same horizontal plane. One end of the limiting block 10 is fixed to the inner wall of the flipping cylinder 2, and the other end is connected to the reset spring 11. The free end of the reset spring 11 is connected to the moving roller group 9 on the side near the feed inlet 3.

[0047] The limiting block 10 is located on one side of the moving roller group 9. The limiting block 10 is connected to the moving roller group 9 by means of the reset spring 11. It is used to assist the moving roller group 9 in resetting so that it always stays on one side of the feed inlet 3 without being subjected to external force.

[0048] When the drive gear 5 drives the moving roller group 9 to move to the side of the discharge port 4, the drive gear 5 disengages from the linkage rack. During the above traction process, the return spring 11 is continuously stretched. Therefore, after the drive gear 5 disengages from the linkage rack, the return spring 11 applies a spring force to the moving roller group 9. Under the traction of this spring force, the moving roller group 9 and the linkage rack move in opposite directions until the moving roller group 9 is reset.

[0049] In some possible embodiments, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 The drive zone has one or two drive gears 5. When there is one drive gear 5, the drive gear 5 has a quarter-tooth portion 51 and a three-quarter-smooth portion 52. The toothed portion 51 is connected to four linkage racks in sequence. When there are two drive gears 5, the drive gear 5 has a half-toothed portion 51 and a half-smooth portion 52. The two drive gears 5 are activated alternately and connected to four linkage racks in sequence. The outer diameter of the smooth portion 52 is smaller than the outer diameter of the toothed portion 51.

[0050] One or two drive gears 5 are mounted on the output shaft of the drive motor. Since the drive gear 5 needs to control all the moving roller groups 9 in the four working areas, if only one drive gear 5 is used, the drive gear 5 is required to have a quarter-tooth portion 51, which needs to mesh with the linkage rack; while its smooth portion 52 will disengage from the other linkage racks to avoid affecting the normal operation of the conveying assembly.

[0051] Since the conveying components within the two partition walls 6 operate independently, two drive gears 5 can be installed on the drive motor; and the two drive gears 5 are used to drive the corresponding conveying components on the two partition walls 6 respectively.

[0052] When two drive gears 5 are installed on the drive motor, the two drive gears 5 work alternately. Half of the drive gear 5 has a serrated portion 51 for meshing with the linkage rack, and the other half has a smooth portion 52 that disengages from the other linkage rack.

[0053] To enable the two drive gears 5 to work alternately, two drive motors can be used. The two drive motors and the two drive gears 5 are set up in a one-to-one correspondence.

[0054] In some possible embodiments, please refer to Figure 7 The movable roller group 9 includes a front roller group, a rear roller group, and a bracket 16. The front roller group and the rear roller group are spaced apart at the lower end of the bracket 16. The linkage rod 8 connects the bracket 16 of the two movable roller groups 9. The front roller group has two spaced front rollers, and the rear roller group has two spaced rear rollers. The distance between the two front rollers is the same as the distance between the two rear rollers.

[0055] Specifically, bracket 16 is used to support iron core 7, and the front wheel assembly and rear wheel assembly located at the lower end of bracket 16 can drive iron core 7 to move.

[0056] The front wheel assembly includes two front rollers, and the rear wheel assembly includes two rear rollers. The front rollers and rear rollers located on the same side are connected and fixed by means of bracket 16 or rods. The linkage rod 8 is connected to the bracket 16 or the connecting shaft between the two front rollers or the connecting shaft between the two rear rollers.

[0057] The middle part of the linkage rod 8 is connected to the linkage rack.

[0058] In some possible embodiments, please refer to Figure 7The tilting cylinder 2 also has a limiting component, which is located on the side of the partition wall 6 near the discharge port 4. The limiting component includes a limiting baffle 12 and a traction spring 13. One end of the limiting baffle 12 is rotatably connected to the side wall of the inner cavity of the partition wall 6 via a hinge shaft 15. The other end of the limiting baffle 12 away from the hinge shaft 15 passes through the side wall of the partition wall 6 and extends into the working area. The limiting baffle 12 is used to fit against the front side of the iron core 7. The traction spring 13 is connected to the side of the limiting baffle 12 near the drive area. A rotating sleeve 14 is sleeved on the output shaft of the drive motor. The rotating sleeve 14 is located on one side of the drive gear 5 and has a connecting hole. The other end of the traction spring 13 is connected to the connecting hole.

[0059] When the iron core 7 has completed its flipping, the limiting component abuts against one side of the iron core 7 to prevent it from shaking or tipping over. The limiting component includes a limiting baffle 12 and a traction spring 13. The lower end of the limiting baffle 12 is hinged to the inner cavity of the partition wall 6, and the limiting baffle 12 rotates around the hinge axis 15. The traction spring 13 is connected to the side wall of the limiting baffle 12 that supports the iron core 7, and the traction spring 13 is located above the hinge axis 15. The traction spring 13 is connected to the partition wall 6 or the output shaft of the drive motor. When no external force is applied, the traction spring 13 drives the limiting baffle 12 to be in an upright state.

[0060] After the iron core 7 has flipped, the moving roller group 9 moves the iron core 7 under the action of the drive motor, and presses the limiting baffle 12. The limiting baffle 12 rotates around the hinge axis 15 under force to make way for the moving roller group 9. When the moving roller group 9 moves the iron core 7 out, only the elastic force applied by the traction spring 13 remains on the limiting baffle 12. Under the action of the traction spring 13, the limiting baffle 12 resets. After the iron core 7 is moved out, the moving roller group 9 needs to reset. The moving roller group 9 presses the limiting baffle 12 in the opposite direction, driving the limiting baffle 12 to press the traction spring 13. After the moving roller group 9 moves away, the traction spring 13 drives the moving roller group 9 to reset.

[0061] Optionally, the traction spring 13 needs to be in a stretched state.

[0062] The side wall of the limiting baffle 12 away from the discharge port 4 is a smooth plane; the side of the limiting baffle 12 near the discharge port 4 is an arc-shaped surface that bulges outward.

[0063] like Figure 6 As shown, to facilitate feeding, the end of the limiting baffle 12 away from the hinge shaft 15 has an arc-shaped transition section.

[0064] like Figure 7 As shown, the end of the moving roller group 9 is connected to two linkage racks, which are spaced apart along the width of the partition wall 6; the limiting baffle 12 is located between the two linkage racks.

[0065] The present invention also provides a method for operating a transformer core flipping device, which uses the above-mentioned transformer core flipping device and includes the following steps:

[0066] S1. Start the support roller, causing it to rotate intermittently toward the discharge port 4;

[0067] S2. Set the feeding station. When any feeding port 3 rotates to the feeding station, it can feed material inward. At this time, the discharging station is located on the side of the tilting cylinder 2 away from the feeding station.

[0068] S3. With the support rollers stopped, the iron core 7 is located on the moving roller group 9 and moves to the vertical partition wall 6 that is attached to the working area by means of the moving roller group 9.

[0069] S4. The support roller rotates, and the iron core 7 located in the working area is flipped and falls onto another moving roller group 9 in the working area.

[0070] S5, the support roller stops, and the moving roller group 9 drives the iron core 7 to move to the discharge port 4.

[0071] Compared with the prior art, the transformer core flipping device operation method provided by the present invention has all the beneficial effects of the above-mentioned transformer core flipping device, realizes the automatic flipping of core 7, reduces the number of manpower and labor intensity, and improves work efficiency; at the same time, it can also realize uninterrupted core 7 flipping operation without stopping the machine and resetting the flipping cylinder 2, reducing reset time and downtime.

[0072] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
