Description

Technical Field

[0001] This application relates to the technical field of paper tube cutting, and more specifically, to a cutting device for the inner paper tube of a steel coil. Background Art

[0002] The inner paper tube of a steel coil is a key component used to support and protect the internal structure of the steel coil during steel production. It is mainly applied in cold rolling and hot rolling production lines to ensure the stability and safety of the steel coil during transportation and storage.

[0003] The original length of the paper tube is uniform and does not meet the requirements of the actual production width. In the past, manual flipping and cutting were carried out on a woodworking saw. The actual cutting was often not precise enough, and the cutting time cost was high. It took a long time to change the specifications of a single barrel. In addition, during the paper tube cutting process, employees needed to hold and operate it throughout the process, posing a risk to employee safety. Summary of the Invention

[0036] Next, a steel coil inner - ring paper tube cutting device according to an embodiment of the present application will be described with reference to the drawings.

[0037] Please refer to Figures 1 to 14, the steel coil inner paper tube cutting device according to the embodiment of the present application includes: a mounting bracket assembly 100, a paper tube rotating support mechanism 200, a tightening mechanism 300, a cutting adjustment mechanism 400, and a single-drive multi-movement mechanism 500.

[0038] Please refer to Figure 1, the installation bracket assembly 100 is set as a three-layer structure. The paper tube rotating support mechanism 200 is rotatably arranged on the top layer of the installation bracket assembly 100. A steel coil inner ring paper tube is sleeved on the free end of the paper tube rotating support mechanism 200. The tightening mechanism 300 is slidably connected inside the paper tube rotating support mechanism 200. One end of the tightening mechanism 300 extends out of the tightening mechanism 300, and one end of the tightening mechanism 300 is installed on the installation bracket assembly 100.

When the single-drive multi-movement mechanism 500 rotates in one direction, it simultaneously drives the paper tube rotating support mechanism 200 and the cutting part on the cutting adjustment mechanism 400 to rotate. When the single-drive multi-movement mechanism 500 rotates in the other direction, it independently drives the paper tube rotating support mechanism 200 to rotate.

The cutting adjustment mechanism 400 first rotates in the direction of driving the cutting part to move left and right. After the left and right positions of the cutting are adjusted in place, the cutting adjustment mechanism 400 reverses and drives the cutting part on the cutting adjustment mechanism 400 to move up and down, making the cutting part on the cutting adjustment mechanism 400 gradually approach the steel coil inner ring paper tube and perform cutting.

Second, the installation end of the steel coil inner ring paper tube is the free end, facilitating the loading and unloading of the steel coil inner ring paper tube. Third, the tightening mechanism 300 fixed by the driving structure stabilizes the steel coil inner ring paper tube, with a simple structure, few driving elements used, and easy layout of the power supply lines. Fourth, for this steel coil inner ring paper tube cutting equipment, the rotation of the steel coil inner ring paper tube and the cutting rotation of the cutting part on the cutting adjustment mechanism 400 use the same drive, and the up and down movement and left and right adjustment movement of the cutting part on the cutting adjustment mechanism 400 share a set of drive, using few driving elements, achieving the purpose of streamlining the circuit system and power supply lines.

The tightening mechanism 300 drives the double swing arm support structure 240, and the double swing arm support structure 240 swings and rises toward the upper side close to the side limit plate 231, and the double swing arm support structure 240 drives the inner ring paper tube of the steel coil to move backward, so that the inner ring paper tube of the steel coil is against the side limit plate 231, thereby realizing the function of positioning the end of the inner ring paper tube of the steel coil.

[0042] See also Figures 1 to 5, the double swing arm support structure 240 includes swing arms 241 and a support plate portion 242. There are two swing arms 241. One ends of the two swing arms 241 are respectively hinged to both ends of the outer wall of the cantilever shaft cylinder 232.

Moreover, the rotation speed of the second drive motor 510 is changed through the speed change of the large sprocket and the small sprocket and the gear meshing, increasing the rotation speed of the cutting part on the cutting adjustment mechanism 400 and increasing the rotation speed of the cutting blade 427.

[0051] Please refer to Figures 1 to 14 , the intermediate transmission shaft member 540 includes a third base 541, an intermediate transmission shaft 542, and a second gear 543.

[0053] Specifically, the working principle of the steel coil inner ring paper tube cutting equipment: During use, the steel coil inner ring paper tube is sleeved on the cantilever shaft tube 232. The driving rod 310 is started, and the driving rod 310 drives the outer ring dial ring 320. The inner ring dial ring 330 slides axially along the support shaft tube 210 with the outer ring dial ring 320. The inner ring dial ring 330 applies force to the transmission force-applying rod 341 through the fixing rod 342. The fixing rod 342 slides along the first chute 220. The other end of the transmission force-applying rod 341 drives the anti-angle support swing rod 350 to open through the mounting cylinder 344. The second chute 233 restricts both sides of the anti-angle support swing rod 350, thereby restricting the rotation of the mounting cylinder 344. And the second chute 233 is used to avoid the interference of the opening of the anti-angle support swing rod 350. The anti-angle support swing rod 350 and the swing arm 241 are set at an anti-angle with opposite inclinations. The anti-angle support swing rod 350 pushes the support plate part 242 to rise, and the swing arm 241 swings accordingly, so that the support plate 2421 abuts against the front and rear ends of the inner wall of the steel coil inner ring paper tube. The concave connecting plate 2422 is recessed inward to reserve a cutting space for the cutting part on the cutting adjustment mechanism 400, reducing the occurrence of the cutting part cutting into the concave connecting plate 2422. The anti-angle support swing rod 350 drives the support plate part 242 to swing upward and rise above the side limiting plate 231. The support plate part 242 drives the steel coil inner ring paper tube to move backward, so that the steel coil inner ring paper tube abuts against the side limiting plate 231, realizing the function of positioning the end of the steel coil inner ring paper tube. The anti-angle support swing rod 350 drives the support plate part 242 to form a stable support for the steel coil inner ring paper tube. The installation end of the steel coil inner ring paper tube is the free end of the cantilever, which is convenient for loading and unloading the steel coil inner ring paper tube. Using the fixed driving rod 310 to stabilize the steel coil inner ring paper tube, the structure is simple, the number of driving elements used is small, and the power supply line is easy to arrange.

[0054] When the second driving motor 510 drives the paper tube rotating support mechanism 200 alone, the second driving motor 510 drives the small pulley, the small pulley drives the large pulley through the transmission belt, the large pulley drives the support shaft cylinder 210 to rotate, the support shaft cylinder 210 drives the cantilever shaft cylinder 232 to rotate, and the cantilever shaft cylinder 232 abuts against the inner ring paper tube of the steel coil through the support plate 2421, thereby driving the inner ring paper tube of the steel coil to rotate, so as to facilitate the measurement of the adjustment and cutting dimensions. At this time, the connecting shaft 552 and the connecting shaft 552 realize the transmission disengagement between the connecting shaft 552 and the one-way shaft 561 through the rolling of the one-way bearing. The one-way shaft 561 has no action, the fixed cylinder 562 and the rhombus shaft 563 have no action, and the cutting blade 427 has no rotation, which is convenient for protecting the installation personnel. When the second driving motor 510 rotates reversely, the second driving motor 510 drives the inner ring paper tube of the steel coil to rotate reversely through the belt transmission structure 520. The second driving motor 510 drives the large sprocket, the large sprocket drives the small sprocket to rotate through the chain, the small sprocket drives the intermediate transmission shaft 542, and the intermediate transmission shaft 542 drives the connecting shaft 552 through the gear meshing principle of the second gear 543 and the third gear 554. The connecting shaft 552 and the one-way shaft 561 are locked through the one-way bearing, realizing the transmission locking between the connecting shaft 552 and the one-way shaft 561. The one-way shaft 561 drives the fixed cylinder 562 to rotate through the universal joint 564, the fixed cylinder 562 drives the rhombus shaft 563, and the rhombus shaft 563 drives the first transmission shaft 426 through another universal joint 564. The first transmission shaft 426 drives the cutting blade 427 to perform cutting operations. The left and right movement and the up and down movement of the cutting blade 427 change the transmission angle through the universal joint 564, and change the transmission length through the expansion and contraction of the fixed cylinder 562 and the rhombus shaft 563 to adapt to the left and right movement and the up and down movement transmission of the cutting blade 427. And through gear meshing, the rotation direction of the inner ring paper tube of the steel coil is opposite to the rotation direction of the cutting blade 427, which is convenient for the cutting operation of the inner ring paper tube of the steel coil. Using the second driving motor 510 to rotate the cutting blade 427 and the inner ring paper tube of the steel coil further reduces the use of driving elements, and the speed of the second driving motor 510 is changed through the speed change of the large sprocket and the small sprocket and the gear meshing, improving the speed of the cutting part on the cutting adjustment mechanism 400 and increasing the speed of the cutting blade 427.

[0055] After the inner paper tube of the steel coil is stabilized, the first driving motor 441 is started. The first driving motor 441 drives the driving gear 442, and the driving gear 442 drives the first gears 414 on the two sets of one-way transmission reciprocating screw members 410. The first gears 414 drive the rotation of the rotating shaft 4131. The rotating shaft 4131 drives the second connecting cylinder 4132. The one-way bearing on the one-way transmission reciprocating screw member 410 with the cutting member 420 is locked. The rotating shaft 4131 drives the reciprocating screw 412 to rotate. The reciprocating screw 412 drives the first reciprocating base 421 to reciprocate through thread matching for left and right adjustment. The cutting blade 427 moves with the first reciprocating base 421. At this time, the one-way bearing on the one-way transmission reciprocating screw member 410 with the lifting member 430 rolls, and the reciprocating screw 412 with the lifting member 430 does not rotate with the rotating shaft 4131, and the second reciprocating base 431 has no movement. After the cutting blade 427 is adjusted in place, the first driving motor 441 reverses. The driving gear 442 drives the first gears 414 on the two sets of one-way transmission reciprocating screw members 410 to reverse. The one-way bearing on the one-way transmission reciprocating screw member 410 with the lifting member 430 is locked. The rotating shaft 4131 drives the reciprocating screw 412 to rotate. The reciprocating screw 412 drives the second reciprocating base 431 to reciprocate through thread matching. The lifting block 432 moves with the second reciprocating base 431. The lower parts at both ends of the lifting block 432 extend into the lower side of the top plate 424. As the lifting block 432 extends into the lower side of the top plate 424, the top plate 424 gradually rises. The top plate 424 pushes the second base 422 to rise through the slide rod 423, and the cutting blade 427 rises accordingly, so that the cutting blade 427 gradually approaches the inner paper tube of the steel coil for cutting operations. On the contrary, when the lifting member 430 gradually leaves the top plate 424, under the elastic force of the compression spring 425, the top plate 424 moves downward, and the cutting blade 427 descends and leaves the inner paper tube of the steel coil. At this time, the one-way bearing on the one-way transmission reciprocating screw member 410 with the cutting member 420 rolls, and the reciprocating screw 412 with the cutting member 420 does not rotate with the one-way transmission shaft part 413, and the first reciprocating base 421 has no movement. The driving member 440 is used to perform actions in four directions of left and right movement and up and down movement of the cutting part on the cutting adjustment mechanism 400, further reducing the use of driving elements and achieving the purpose of streamlining the circuit system and the power supply line.

[0056] It should be noted that the specific model specifications of the electric push rod, the first driving motor 441, and the second driving motor 510 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.
