Description

Technical Field

[0001] This utility model relates to the field of coreless cutting machines, specifically a novel coreless cutting machine for steel coils. Background Technology

[0002] Steel coils are a common form of steel, typically formed by rolling hot-rolled or cold-rolled steel sheets into cylindrical shapes. Steel coils are widely used in various industries such as construction, automobiles, machinery, and home appliances. They are an important raw material in the steel processing and manufacturing process. Steel coils are easy to store, transport, and process, thus occupying an important position in the steel market.

[0003] The new type of coreless steel coil uncoiling machine is an innovative piece of equipment in the field of steel coil uncoiling technology. It mainly solves the shortcomings of traditional uncoiling machines that require a mandrel to install the steel coil. Through its unique mandrelless design, this equipment achieves fast, safe, and stable uncoiling of steel coils, and has significant technical advantages and application value. A crane is used to directly lift the steel coil onto the transport trolley of the coreless steel coil uncoiling machine. Then, through the movement and lifting of the transport trolley, the coreless steel coil is transported to the idler roller assembly. Through the synchronous drive of the idler rollers, the steel coil begins to gradually unwind. During this process, the design of the idler roller assembly ensures the stability of the steel coil and the smoothness of uncoiling. At the same time, the setting of the strips ensures that the idler rollers are evenly stressed after the steel coil is installed, thereby extending the service life of the idler rollers.

[0004] Traditional coreless steel coil cutters require manual rotation of support bars to provide auxiliary support to the rollers when the transport trolley moves the steel coil onto the idler rollers. This bearing method is not convenient to operate and reduces the efficiency of the coreless steel coil cutter. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a new type of coreless steel coil cutting machine to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A novel coreless steel coil cutting machine, comprising a coreless steel coil cutting machine and a steel coil transport vehicle, wherein a rotating shaft is rotatably mounted on the outer wall of the coreless steel coil cutting machine, and a gear is fixedly mounted on one end of the rotating shaft, and an auxiliary support rod is fixedly mounted on the other end of the rotating shaft, an auxiliary support seat is fixedly mounted on the outer wall of the auxiliary support rod, a connecting rod is slidably mounted on the outer wall of the coreless steel coil cutting machine, and a first limiting strip is fixedly mounted on the end of the connecting rod, and a second limiting strip is fixedly mounted on the outer wall of the connecting rod, and a rack corresponding to the gear is fixedly mounted on the outer wall of the connecting rod, and a locking component for limiting the auxiliary support rod is installed on the outer wall of the coreless steel coil cutting machine.

[0007] By adopting the above technical solution, it is ensured that under the drive of the steel coil transport vehicle, the support rod on the outer wall of the connecting rod moves due to the restriction of the first and second limiting strips. Through the meshing of the rack and gear, the auxiliary support rod starts to rotate, ultimately achieving the purpose of synchronously rotating the auxiliary support rod through the movement of the steel coil transport vehicle. At the same time, through the setting of the auxiliary support seat, the auxiliary support rod can smoothly support the rollers inside the coreless steel coil cutter after rotating to the appropriate position. Furthermore, through the setting of the locking component, the auxiliary support rod is restricted by the limiting block after moving to the appropriate position, and the limiting block is restricted by the setting of the limiting ball.

[0008] Furthermore, the gear is located near the end of the steel coil transport vehicle, and the auxiliary support is located on the outer wall away from the gear.

[0009] By adopting the above technical solution, it is ensured that the auxiliary support seat can smoothly support the inner roller of the coreless steel coil cutter through the rotation of the gear.

[0010] Furthermore, the outer wall of the auxiliary support is designed to be inclined, and the first limiting bar is located at the end of the connecting rod away from the gear.

[0011] By adopting the above technical solution, it is ensured that the auxiliary support seat can better fit the rollers inside the coreless steel coil cutter, and at the same time, it is ensured that the steel coil transport vehicle can smoothly push the first limiting bar when moving.

[0012] Furthermore, the second limiting bar is located on the outer wall of the connecting rod near the first limiting bar, and the outer walls of both the first and second limiting bars are in contact with the outer wall of the steel coil transport vehicle.

[0013] By adopting the above technical solution, it is ensured that the first or second restriction bar can be moved smoothly when the steel coil transport vehicle moves.

[0014] Furthermore, the rack is located at the end near the second limiting bar, and the maximum rotation angle of the gear is 270 degrees.

[0015] By adopting the above technical solution, it is ensured that the non-rotation of gears will not affect the normal use of the coreless steel coil cutting machine.

[0016] Furthermore, the locking assembly includes a support rod, a limiting block, a limiting block, and a limiting ball. The support rod is fixedly installed on the outer wall of the coreless steel coil cutting machine, and a limiting block is rotatably installed at the end of the support rod, while a limiting block is fixedly installed at the end of the support rod.

[0017] By adopting the above technical solution, it is ensured that the end of the auxiliary support rod will no longer continue to rotate under the restriction of the limiting block.

[0018] Furthermore, limiting balls corresponding to the limiting block are fixedly installed on the end of the auxiliary support rod and the outer wall of the limiting block. The limiting block is designed in a "冂" shape structure, and the limiting block is located at the end of the support rod close to the auxiliary support rod.

[0019] By adopting the above technical solution, it is ensured that the limiting block will not rotate under the limitation of the limiting ball, and at the same time, the limiting block can better limit the limiting ball.

[0020] To sum up, the main beneficial effects of the present utility model are as follows:

[0021] By providing a rotating shaft, a gear, an auxiliary support rod, an auxiliary support seat, a connecting rod, a first limiting strip, a second limiting strip and a rack, the present utility model ensures that under the drive of the steel coil transport vehicle, the support rod on the outer wall of the connecting rod is driven to move through the limitation of the first limiting strip and the second limiting strip, and the auxiliary support rod is driven to rotate through the meshing of the rack and the gear, and finally the purpose of driving the auxiliary support rod to rotate synchronously through the movement of the steel coil transport vehicle is achieved. At the same time, through the setting of the auxiliary support seat, the auxiliary support rod can smoothly further support the roller in the coreless coil uncoiler after rotating to a suitable position. At the same time, through the setting of the locking component, after the auxiliary support rod moves to a suitable position, the auxiliary support rod is restricted by the limiting block, and at the same time, the limiting block is restricted by the limiting ball through the setting of the limiting ball.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] A new type of coreless steel coil cutting machine, such as Figure 1 - Figure 4 As shown, the device includes a coreless steel coil cutter 1 and a steel coil transport vehicle 2. A rotating shaft 3 is rotatably mounted on the outer wall of the coreless steel coil cutter 1, with a gear 4 fixedly mounted at one end of the shaft 3 and an auxiliary support rod 5 fixedly mounted at the other end. An auxiliary support seat 6 is fixedly mounted on the outer wall of the auxiliary support rod 5. A connecting rod 7 is slidably mounted on the outer wall of the coreless steel coil cutter 1, with a first limiting strip 8 fixedly mounted at the end of the connecting rod 7 and a second limiting strip 9 fixedly mounted on the outer wall of the connecting rod 7. A rack 10 corresponding to the gear 4 is fixedly mounted on the outer wall of the connecting rod 7. A locking assembly for limiting the auxiliary support rod 5 is installed on the outer wall of the coreless steel coil cutter 1. The steel coil transport vehicle 2 moves... The first limiting strip 8, which is attached to the steel coil transport vehicle 2, moves simultaneously under the drive of the steel coil transport vehicle 2, thereby driving the connecting rod 7 to start moving. At this time, the rack 10 on the outer wall of the connecting rod 7 moves simultaneously under the drive of the connecting rod 7. As the steel coil transport vehicle 2 continues to move, the rack 10 begins to mesh with the gear 4, thereby driving the rotating shaft 3 on the outer wall of the gear 4 to rotate simultaneously. Under the rotation of the rotating shaft 3, the auxiliary support rod 5 rotates simultaneously. At this time, as the end of the auxiliary support rod 5 comes into contact with the limiting block 13 at the end of the support rod 11, the rack 10 and the gear 4 no longer come into contact. The steel coil transport vehicle 2 drives the coreless steel coil to be installed in a suitable position in the coreless steel coil cutter 1.

[0030] Please see Figure 2 and Figure 4 Gear 4 is located at the end near the steel coil transport vehicle 2, and auxiliary support seat 6 is located on the outer wall away from gear 4. The rotation of gear 4 drives the auxiliary support rod 5 to rotate at the same time, so that the auxiliary support seat 6 can smoothly support the rollers inside the steel coil coreless cutting machine 1, ensuring that the rotation of gear 4 can smoothly support the rollers inside the steel coil coreless cutting machine 1.

[0031] Please see Figure 2 and Figure 4The outer wall of the auxiliary support seat 6 is inclined. The first limiting bar 8 is located at the end of the connecting rod 7 away from the gear 4. During the rotation of the auxiliary support seat 6, due to the inclined design of the outer wall of the auxiliary support seat 6, the auxiliary support seat 6 can better adapt to the rollers in the coreless steel coil cutter 1 while moving. At the same time, when the steel coil transport vehicle 2 moves towards the coreless steel coil cutter 1, it can smoothly drive the connecting rod 7 to move through the first limiting bar 8, ensuring that the auxiliary support seat 6 can better fit the rollers in the coreless steel coil cutter 1, and ensuring that the steel coil transport vehicle 2 can smoothly push the first limiting bar 8 when moving.

[0032] Please see Figure 2 and Figure 4 The second limiting bar 9 is located on the outer wall of the connecting rod 7 near the first limiting bar 8, and the outer walls of both the first limiting bar 8 and the second limiting bar 9 are in contact with the outer wall of the steel coil transport vehicle 2. When the steel coil transport vehicle 2 moves away from the coreless steel coil cutter 1, the connecting rod 7 is moved by pushing the second limiting bar 9, so as to ensure that the first limiting bar 8 or the second limiting bar 9 can be moved smoothly at the same time when the steel coil transport vehicle 2 moves.

[0033] Please see Figure 2 and Figure 4 The rack 10 is located at the end near the second limiting bar 9, and the maximum rotation angle of the gear 4 is 270 degrees. When the connecting rod 7 moves, it drives the rack 10 to move at the same time. At this time, the steel coil transport vehicle 2 can still continue to move after rotating the auxiliary support rod 5, ensuring that the gear 4 does not rotate and will not affect the normal use of the coreless steel coil cutter 1.

[0034] Please see Figure 4 The locking assembly includes a support rod 11, a limiting block 12, a limiting block 13, and a limiting ball 14. The support rod 11 is fixedly installed on the outer wall of the coreless steel coil cutter 1, and the limiting block 12 is rotatably installed at the end of the support rod 11. The limiting block 13 is also fixedly installed at the end of the support rod 11. As the auxiliary support rod 5 continues to rotate, until the end of the auxiliary support rod 5 comes into contact with the limiting block 13, the user can rotate the limiting block 12 to ensure that the end of the auxiliary support rod 5 no longer continues to rotate under the restriction of the limiting block 13.

[0035] Please see Figure 4, a limiting ball 14 corresponding to the limiting block 12 is fixedly installed at the end of the auxiliary support rod 5 and on the outer wall of the limiting block 13. The limiting block 12 is designed in a "冂" - shaped structure, and the limiting block 13 is located at the end of the support rod 11 close to the auxiliary support rod 5. By rotating the limiting block 12, the limiting block 12 is disengaged from the limiting ball 14. As the limiting block 12 continues to rotate, under the restriction of the limiting ball 14, the limiting ball 14 restricts the limiting block 12, ensuring that the limiting block 12 does not rotate under the restriction of the limiting ball 14. At the same time, the limiting block 12 can better restrict the limiting ball 14.

[0036] The working principle of the present utility model is as follows: When the user places the coreless steel coil on the steel coil transport vehicle 2, the steel coil transport vehicle 2 starts to move towards the direction close to the coreless steel coil cutting machine 1. At this time, the first limiting strip 8 adhered to the steel coil transport vehicle 2 moves simultaneously under the drive of the steel coil transport vehicle 2, thereby driving the connecting rod 7 to start moving. At this time, the rack 10 on the outer wall of the connecting rod 7 moves simultaneously under the drive of the connecting rod 7. As the steel coil transport vehicle 2 continues to move, the rack 10 starts to mesh with the gear 4, thereby driving the rotating shaft 3 on the outer wall of the gear 4 to rotate simultaneously. Under the rotation of the rotating shaft 3, the auxiliary support rod 5 rotates simultaneously. At this time, as the end of the auxiliary support rod 5 abuts against the limiting block 13 at the end of the support rod 11, at this time, the rack 10 and the gear 4 are no longer in contact. The steel coil transport vehicle 2 installs the coreless steel coil at a suitable position on the coreless steel coil cutting machine 1;

[0037] The user rotates the limiting block 12 on the outer wall of the support rod 11 to restrict the limiting block 13 at the end of the support rod 11 at the end of the auxiliary support rod 5. At the same time, due to the setting of the limiting ball 14, as the user continues to rotate the limiting block 12, the limiting block 12 coincides with the limiting ball 14. Due to the restriction of the limiting ball 14, the limiting block 12 no longer continues to rotate. When the steel coil transport vehicle 2 needs to transport the next coreless steel coil, the user first rotates the limiting block 12 of the support rod 1 to separate the limiting block 12 from the limiting ball 14. At this time, the steel coil transport vehicle 2 starts to move away from the coreless steel coil cutting machine 1, thereby pushing the second limiting strip 9. Through the transmission of the second limiting strip 9, the rack 10 drives the gear 4 to rotate the auxiliary support rod 5. As the auxiliary support rod 5 continues to rotate until the auxiliary support rod 5 rotates to a position where it does not affect the entry of the coreless steel coil, at this time, the rack 10 is no longer meshed with the gear 4, and at this time, the steel coil transport vehicle 2 waits for the placement of the next coreless steel coil.
