Description

Technical Field

[0001] The present application relates to the field of mechanical automation, and in particular to a length-setting machine. Background Art

[0002] In the steel rolling industry, billets and finished steel products are specified in specific lengths according to product standards. These lengths effectively conserve metal resources and facilitate production and transportation.

[0003] Related art length-cutting machines typically include a conveyor mechanism consisting of a support frame and multiple rollers rotatably connected to the frame, arranged along the length of the frame. A drive motor is mounted on the frame to drive the rollers. When a steel strip or bar is placed on the conveyor mechanism, the drive motor is activated, rotating each roller and conveying the strip or bar.

[0004] However, when the steel belt or steel bar moves on the conveying mechanism, the steel belt or steel bar may be stuck in the gap where one end of the roller is connected to the support frame, affecting the normal operation of the conveying mechanism. Utility Model Content

[0005] In order to ensure the normal operation of the transmission mechanism, the present application provides a length-fixing machine.

[0006] The present application provides a length-fixing machine adopting the following technical solution:

[0007] A sizing machine includes a conveying mechanism, which includes a support frame and multiple rollers rotatably connected to the support frame. The support frame is equipped with a driving mechanism that drives the multiple rollers to rotate together. The support frame is equipped with a limiting mechanism, which includes two limiting members located between two adjacent rollers, each of which is vertically arranged upward and protrudes from the conveying mechanism.

[0008] By adopting the above technical solution, the drive mechanism drives the multiple rollers to rotate together. This rotation of the multiple rollers can convey the steel strip or steel bar on the conveyor mechanism. As the steel strip or steel bar moves on the conveyor mechanism, it passes between two limiters. The limiters prevent the steel strip or steel bar from entering the gap between one end of the roller and the support frame, thus ensuring the normal operation of the conveyor mechanism.

[0009] Preferably, the support frame is equipped with an adjustment component that drives the two limit members to move toward or away from each other, and the adjustment component includes a pair of mounting blocks installed at the bottom end of the support frame, a two-way screw is rotatably connected between the pair of mounting blocks, the lower end of each limit member is threadedly connected to one end of the two-way screw, and a guide rod is also fixedly connected between the pair of mounting blocks, the lower end of each limit member is slidably connected to the guide rod, and one end of the two-way screw passes through the corresponding mounting block and is equipped with a handwheel.

[0010] By adopting the above technical solution, turning the handwheel drives the bidirectional screw, which in turn drives the two limiters to move toward or away from each other. The guide rod guides the movement of the two limiters. This makes it easy to adjust the distance between the two limiters to accommodate different numbers or widths of steel strips or bars.

[0011] Preferably, one end of the bidirectional screw passes through the handwheel, a connecting hole is provided at one end of the bidirectional screw, a locking hole passing through the handwheel is provided on the handwheel, a pin is inserted into the locking hole, and the pin is simultaneously inserted into the connecting hole.

[0012] By adopting the above technical solution, the handwheel and the bidirectional screw are locked by the pin, so turning the handwheel can easily drive the bidirectional screw to rotate. When the bidirectional screw does not need to be rotated, the pin is pulled to disengage the handwheel and the bidirectional screw, and the lock between the handwheel and the bidirectional screw is released, reducing the possibility of the bidirectional screw being rotated due to accidental contact with the handwheel.

[0013] Preferably, one end of the bidirectional lead screw is fixedly connected to two limit blocks, the handwheel is located between the two limit blocks and each limit block contacts the handwheel.

[0014] By adopting the above technical solution, the two limit blocks prevent the handwheel from detaching from the bidirectional lead screw when the handwheel and the bidirectional lead screw are unlocked.

[0015] Preferably, two driving cylinders are fixedly connected to the support frame, and the piston rod of each driving cylinder vertically penetrates the support frame downward and is fixedly connected to a corresponding mounting block.

[0016] By adopting the above technical solution, the two driving cylinders are started at the same time, and the extension and retraction of the piston rods of the two driving cylinders facilitate the lifting and lowering of the corresponding mounting blocks, thereby facilitating the lifting and lowering of the adjustment assembly and the two limit members, thereby adjusting the height of the upper end of each limit member protruding from the roller shaft.

[0017] Preferably, the limiting member includes a connecting block that is threadedly connected to the bidirectional lead screw and slidingly connected to the guide rod, and the upper end of the connecting block is rotatably connected to a limiting roller arranged vertically upward.

[0018] By adopting the above technical solution, the limiting roller is rotatably connected to the connecting block, and the friction of the steel belt or steel bar drives the limiting roller to rotate, thereby reducing the wear of the steel belt or steel bar.

[0019] Preferably, a protective layer is sleeved on the outer side of the limiting roller, and the inner wall of the protective layer is in close contact with the outer wall of the limiting roller.

[0020] By adopting the above technical solution, the protective layer further reduces the wear of the limiting roller on the steel belt or steel bar, and at the same time facilitates the replacement of the protective layer.

[0021] Preferably, the outer wall of the protective layer is provided with a plurality of protrusions.

[0022] By adopting the above technical solution, the setting of the protrusions increases the friction between the protective layer and the steel belt or steel bar, making it easier for the steel belt or steel bar to drive the limiting roller to rotate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The limiter restricts the steel belt or steel bar from entering the gap between one end of the roller and the support frame, ensuring the normal operation of the transmission mechanism;

[0025] 2. It is easy to adjust the distance between the two limiters to accommodate steel strips or bars of different quantities or widths;

[0026] 3. Adjust the height of the upper end of each limiter protruding from the roller shaft to adapt to steel strips or steel bars of different heights. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-Figure 3This application is described in further detail.

[0032] The embodiment of the present application discloses a length-fixing machine. Figure 1 and Figure 2 The length-fixing machine includes a conveying mechanism 1, which includes a support frame 11, a plurality of rollers 12 rotatably connected to the support frame 11, and the plurality of rollers 12 are arranged along the length direction of the support frame 11. A driving mechanism for driving the plurality of rollers 12 to rotate together is installed on the support frame 11.

[0033] A limiting mechanism 2 for limiting the central transmission of the steel strip or bar is also mounted on the support frame 11. The limiting mechanism 2 includes two limiting members 21 located between two adjacent rollers 12, each of which is vertically upwardly disposed and protrudes from the transmission mechanism 1.

[0034] The drive mechanism drives the multiple rollers 12 to rotate, thereby conveying the steel strip or steel bar on the conveyor mechanism 1. At the same time, the steel strip or steel bar conveyed on the conveyor mechanism 1 passes between two stoppers 21. The stoppers 21 restrict the steel strip or steel bar from entering the gap where one end of the rollers 12 connects to the support frame 11, ensuring the normal operation of the conveyor mechanism 1.

[0035] An adjustment assembly 22 for adjusting the spacing between the two stoppers 21 is mounted on the support frame 11. Mounted at the bottom end of the support frame 11, the adjustment assembly 22 comprises a pair of mounting blocks 221 and a bidirectional lead screw 222. The mounting blocks 221 are mounted at the bottom end of the support frame 11. The lead screw 222 is rotatably connected between the mounting blocks 221. A guide rod 223 is also fixedly connected between the mounting blocks 221. The lower end of each stopper 21 is threadedly connected to one end of the lead screw 222 and is also slidably connected to the guide rod 223. One end of the lead screw 222 passes through the corresponding mounting block 221 and is mounted with a handwheel 224.

[0036] The handwheel 224 of the bidirectional screw 222 can be rotated to drive the rotation of the bidirectional screw 222, thereby driving the two limiting members 21 to move toward or away from each other, so as to facilitate the adjustment of the distance between the limiting members 21.

[0037] Reference Figure 2 and Figure 3 One end of the bidirectional screw 222 is fixedly connected to two limit blocks 225, and the handwheel 224 is penetrated by the bidirectional screw 222 and is located between the two limit blocks 225. Each limit block 225 contacts the handwheel 224, limiting the handwheel 224 from detaching from the bidirectional screw 222, thereby ensuring the stability of the adjustment component 22.

[0038] A connecting hole 2221 is defined at one end of the bidirectional screw 222, near the handwheel 224. Connecting hole 2221 is perpendicular to the axis of the bidirectional screw 222. A locking hole 2241 is defined in the handwheel 224 and extends through the handwheel 224. The locking hole 2241 is also perpendicular to the axis of the bidirectional screw 222. A pin 226 is inserted into the locking hole 2241 and engages with the connecting hole 2221, thereby locking the bidirectional screw 222 and the handwheel 224.

[0039] Reference Figure 1 and Figure 2 Two drive cylinders 3 are fixedly connected to the support frame 11, one drive cylinder 3 corresponding to each mounting block 221. The piston rod of each drive cylinder 3 extends vertically downward through the support frame 11 and is fixedly connected to the corresponding mounting block 221. By adjusting the extension and retraction of the piston rod of the drive cylinder 3, the elevation of the mounting block 221 is controlled, ultimately achieving the height change of the limiter 21. The synchronous operation of the two drive cylinders 3 ensures the stable vertical movement of the adjustment assembly 22, allowing the vertical adjustment of the limiter 21 to be automated without manual intervention.

[0040] The limiting member 21 includes a connecting block 211 threadedly connected to a bidirectional lead screw 222. Each connecting block 211 is penetrated by a guide rod 223, thereby slidingly connected to the guide rod 223. The upper end of each connecting block 211 is rotatably connected to a limiting roller 212 arranged vertically upward. A protective layer 4 is sleeved on the outer side of the limiting roller 212. The protective layer 4 can be made of polyurethane or other special rubber to reduce wear on the steel belt or steel bar. The outer wall of the protective layer 4 is provided with a plurality of protrusions 41. The protrusions 41 can increase the friction with the steel belt or steel bar, making it easier for the steel belt or steel bar to drive the limiting roller 212 to rotate.

[0041] The operating principle of a sizing machine according to an embodiment of the present application is as follows: a driving mechanism is activated to rotate each roller 12, and the steel strip or bar to be conveyed is inserted between two stoppers 21 from one end of the conveyor mechanism 1, thereby being conveyed by the conveyor mechanism 1. The distance between the two stoppers 21 and the height of the stoppers 21 protruding from the rollers 12 are adjusted according to the size or quantity of the steel strip or bar to be conveyed.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
