Description

Technical Field

[0001] This invention relates to the field of steel strip cutting technology, and in particular to a steel strip feeding and cutting device. Background Technology

[0002] After steel wire is coiled, each bundle of coil is tightly bound axially at four points at 90-degree intervals along its diameter with packing wire. During handling or transportation, the packing wire may break and spill out, some of which may extend beyond the outside of the transport train carriages, significantly impacting railway transport safety. The solution is to longitudinally wrap steel strips around the outer periphery of the coils and then weld the steel strips to the packing wires using a welding robot. However, this complete production line includes steel strip feeding, cutting, conveying, and welding. The existing cutting process uses a laser cutting machine, which cannot control the length of the steel strip, often exceeding the normal usable length. This results in wasted steel strips and increased production costs. Summary of the Invention

[0016] (1) This invention provides a steel strip feeding and cutting device. The conveying component can transport the steel strip to the cutting component, which can then cut the steel strip. The driving component can drive the steel strip to be conveyed on the guiding component, which can then cut the steel strip. The cutting component can then cut the steel strip. The reduction motor can drive the first rotating disk to rotate, which in turn drives the steel strip to rotate, thus enabling the steel strip to be conveyed. The corrugated handwheel and the threaded part can easily place the steel strip roll on the first rotating disk. The first linear guide rail can adjust the tension of the steel strip, which can then be cut. The first slide cylinder can drive the finger cylinder to move back and forth, which can then be used to clamp and transport the steel strip.

[0023] The invention will now be further described with reference to the accompanying drawings.

[0024] Please see Figures 1 to 3The present invention provides an embodiment of a steel strip feeding and cutting device, comprising a worktable 1 and a conveying assembly. The conveying assembly transports the steel strip to a cutting assembly 5, facilitating the cutting assembly 5 to cut the steel strip. A mounting plate 2 is fixed to the rear side of the worktable 1 for mounting various components. The conveying assembly includes a driving assembly 3 mounted on the worktable 1 and a guiding assembly 4 and a cutting assembly 5 mounted on the mounting plate 2. The driving assembly 3 drives the steel strip to be conveyed on the guiding assembly 4 for subsequent cutting, and the cutting assembly 5 cuts the steel strip.

[0025] The drive assembly 3 includes a first rotating disk 31 disposed on the upper platform of the workbench 1 for placing steel strip. The first rotating disk 31 is driven by a reduction motor 32, which can drive the first rotating disk 31 to rotate, thereby driving the steel strip to rotate and enabling the steel strip to be conveyed. A limit block (not shown) is fixed in the middle of the top surface of the first rotating disk 31. A steel strip roll is sleeved on the limit block to limit the steel strip roll. A second rotating disk 33 is placed above the limit block.

[0026] A support block 34 is fixed to the center of the bottom surface of the first rotating disk 31, and a support rod (not shown) is fixed to the center of the top surface of the support block 34. The upper end of the support rod penetrates the first rotating disk 31 and extends above the second rotating disk 33. A corrugated handwheel 35 is screwed to the upper end of the support rod. The upper end of the support rod has threads, so that the steel strip roll can be easily placed on the first rotating disk 31 by engaging the corrugated handwheel 35 with the threads. When the steel strip roll is used up and needs to be added, the corrugated handwheel 35 is turned off, the second rotating disk 33 is picked up, the steel strip roll is put on the limiting block, then the second rotating disk 33 is put on the support rod, and finally the corrugated handwheel 35 is turned on.

[0027] The lower platform of the workbench 1 is equipped with the geared motor 32. The output shaft of the geared motor 32 passes through the upper platform and is fixedly connected to the support block 34. The output shaft is connected to the upper platform via a bearing seat 36, which facilitates the rotation of the output shaft of the geared motor 32. Starting the geared motor 32 drives the support block 34 to rotate, which in turn drives the steel strip roll to rotate, thus conveying the steel strip roll.

[0028] The guide assembly 4 includes a first guide wheel 41 mounted on the upper platform, and a plurality of second guide wheels 42 mounted on the front side of the mounting plate 2. A steel strip drawn from a steel strip coil passes sequentially around the first guide wheel 41 and the second guide wheels 42. A rodless cylinder 43 is mounted on the upper support of the workbench 1. The rodless cylinder 43 is driven by a drive motor 44, which can move the slide of the rodless cylinder 43 left and right. A first slide cylinder 45 is mounted on the slide of the rodless cylinder 43. The first slide cylinder 45 can be of model HLQ16X40, but is not limited to this. The first slide cylinder 45 can drive the finger cylinder 46 to move back and forth, so that the subsequent finger cylinder 46 can clamp and transport the steel strip. The finger cylinder 46 is installed on the rear side of the slide of the first slide cylinder 45. The finger cylinder 46 can be of model HFD16X15, but is not limited to this. The finger cylinder 46 is fixed with a gripper 47. The finger cylinder 46 can drive the gripper 47 to clamp the steel strip.

[0029] When the steel strip is conveyed to the cutting point, the first slide cylinder 45 is activated to drive the finger cylinder 46 to extend. Then, the finger cylinder 46 is activated to drive the gripper 47 to clamp the steel strip. The drive motor 44 drives the rodless cylinder 43 to start, thereby driving the slide on the rodless cylinder 43 to move, thus moving the steel strip to facilitate subsequent cutting.

[0030] Two second guide wheels 42 on the right side are located at the upper and lower ends of the mounting plate 2, respectively. A first linear guide rail 48 is longitudinally fixed at the right end of the front side of the mounting plate 2. The second guide wheel 42 at the lower right end is mounted on the slide of the first linear guide rail 48. The first linear guide rail 48 has several threaded holes longitudinally. The slide of the first linear guide rail 48 is connected to the threaded holes by bolts, so that the height of the second guide wheel 42 at the lower right end can be adjusted, thereby adjusting the tension of the steel strip and facilitating subsequent cutting.

[0031] The second guide wheel 42 at the upper right end is fixed to the mounting plate 2 by a fixing plate 49. The fixing plate 49 is fixed to the left side of the second guide wheel 42 at the upper right end with a mounting block 410 for mounting the second slide cylinder 411. The second slide cylinder 411 is mounted on both the left and right ends of the top surface of the mounting block 410. The model of the second slide cylinder 411 can be HLH10X20, but is not limited to this. The second slide cylinder 411 can drive the pressure block 412 to press and fix the steel strip, which is convenient for subsequent cutting of the steel strip. The pressure block 412 is fixed on the front side of the push plate of the second slide cylinder 411. The top surface of the mounting block 410 is provided with a groove that matches the pressure block 412, which can better press the steel strip.

[0032] When the steel strip needs to be cut, the second slide cylinder 411 is activated to move the pressure block 412 downward, thereby pressing and fixing the steel strip.

[0033] The cutting assembly 5 includes a laser cutting machine 51. The laser cutting machine 51 is mounted on the mounting plate 2 above the fixed plate 49. A first telescopic cylinder 52 is mounted on the mounting plate 2 to the left of the laser cutting machine 51. The first telescopic cylinder 52 can drive the pressure plate 53 to move downward, thereby pressing the steel strip onto the auxiliary plate 7 to facilitate subsequent cutting. The pressure plate 53 is fixed to the end of the push rod of the first telescopic cylinder 52.

[0034] The mounting plate 2 is equipped with several second telescopic cylinders 6. The second telescopic cylinders 6 can drive the auxiliary plate 7 to move up and down, so that when the finger cylinder 46 drives the steel strip to move, it can support the steel strip and prevent the steel strip from sagging. This allows the length of the steel strip to be controlled and avoids waste of steel strip. The push rod end of the second telescopic cylinder 6 is connected to an auxiliary plate 7 via a floating joint (not shown). The floating joint allows the second telescopic cylinder 6 to drive the auxiliary plate 7 to move stably.

[0035] The auxiliary plate 7 has several second linear guide rails 8 mounted longitudinally on its rear side. The auxiliary plate 7 can slide on the second linear guide rails 8 via a slider, which enables the auxiliary plate 7 to move more stably. The slider of the second linear guide rail 8 is fixedly connected to the mounting plate 2.

[0036] The usage method of this embodiment is as follows:

[0037] Step S1: Place the steel belt on the limit block, place the second rotating disk 33 on the support rod, screw the corrugated handwheel 35 on the support rod, then pass the first guide wheel 41 and the second guide wheel 42 around the first guide wheel 41 and the second guide wheel 42 in sequence, and finally pass the second guide wheel 42 on the upper right side. Then start the reduction motor 32 to drive the steel belt to rotate.

[0038] Step S2: After the first end of the steel strip passes through the groove, the first slide cylinder 45 is activated to drive the finger cylinder 46 to move forward. After the finger cylinder 46 is activated to drive the gripper 47 to clamp the steel strip, the drive motor 44 drives the rodless cylinder 43 to start, thereby driving the finger cylinder 46 to move to the left.

[0039] Step S3: As the rodless cylinder 43 moves the steel belt to the left, the second telescopic cylinder 6 is activated in sequence, thereby driving the auxiliary plate 7 to move upward and lift the steel belt, so that the steel belt is on the same horizontal plane, preventing the steel belt from sagging and exceeding the normal length of use, thus avoiding waste.

[0040] Step S4: When the steel strip moves to the left end, the second slide cylinder 411 is activated to drive the pressure block 412 to move downward, thereby pressing and fixing the steel strip. The first telescopic cylinder 52 is activated to drive the pressure plate 53 to move downward, thereby pressing the steel strip onto the auxiliary plate 7.

[0041] Step S5: Start the laser cutting machine 51 to cut the steel strip.

[0042] In one embodiment of the present invention, there are two conveying components, located at the left and right ends of the workbench 1 respectively, and conveying in opposite directions. This allows the second conveying component to be started immediately after the steel strip roll in the first conveying component is used up, and then the first conveying component is replenished with steel strip rolls, thereby improving work efficiency.

[0043] In one embodiment of the present invention, a drag chain 9 is provided on the support base in front of the rodless cylinder 43. The drag chain 9 is mounted on the support base via a track groove for placing the wires of various components.

[0044] The above description is only a preferred embodiment of the present invention and should not be construed as a limitation of this application. All equivalent changes and modifications made in accordance with the scope of the patent application of the present invention should be included in the scope of the present invention.
