[0002] After the steel strip is processed into a thin steel strip, the surface is smoother and the thickness is comparable to that of paper. The thin steel strip needs to be wound into a roll using a winder for easy transportation and storage. The winding shaft of the winder needs to be covered with an inner liner to isolate the steel strip from the winding shaft to prevent the winding shaft from scratching the surface of the steel strip. At the same time, the inner liner can also support the steel paper roll without deformation during transportation, thereby improving the quality of the steel paper roll.

[0003] At present, the inner liner of the steel paper winding machine usually needs to be installed manually. Due to the large size of the inner liner, manual handling and installation is very time-consuming and labor-intensive, and there are certain safety hazards. At the same time, the inner liner will also take up a large space when placed or transported, and only two spare ones can be temporarily stored near the winding machine, which requires workers to pull materials frequently, increasing work intensity.

[0034] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0035] Reference Figure 1-Figure 3 The embodiment of the present invention provides a steel strip winding machine for automatically placing an inner liner, including a machine base 1 placed on a horizontal plane, the machine base 1 is arranged in an "L" shape, including a bottom beam 11 and a mounting plate 12 connected to the bottom beam 11, and a winding mechanism 2 is arranged on the mounting plate 12, and the winding mechanism 2 is arranged parallel to the bottom beam 11. The winding mechanism 2 is provided with an inner liner composed of four inner liner arc plates 101, and the two adjacent inner liner arc plates 101 are fixed by a clamping structure 3 arranged on the winding mechanism 2, and the complete inner liner drives the steel strip to be wound and stored. The machine base 1 is also connected to a silo mechanism 4 for storing the inner liner arc plates 101, the silo mechanism 4 is placed close to the mounting plate 12, and a plurality of inner liner arc plates 101 are stacked and stored in the silo mechanism 4, and the silo mechanism 4 pushes the inner liner arc plate 101 on the top layer to pass through the mounting plate 12, clamped on the winding mechanism 2, and wraps the winding mechanism 2 to prevent the winding mechanism 2 from scratching the surface of the steel strip.

[0036] The mounting plate 12 is provided with a conveying window 121 and a plurality of rotating shafts 122. The conveying window 121 is opened above the winding mechanism 2, so that the silo mechanism 4 can convey the inner liner arc plate 101 to the winding mechanism 2. The plurality of rotating shafts 122 are arranged on the side of the mounting plate 12 opposite to the winding mechanism 2 and below the conveying window (121). The plurality of rotating shafts 122 are sleeved with pulleys, and the plurality of pulleys are rotated synchronously by means of belts 123 tightened on the plurality of pulleys. One of the rotating shafts 122 is connected to a first motor 13, which drives the rotating shaft 122 to rotate, and then transmits the transmission to the remaining rotating shafts 122 through the belt 123, so that the pulleys on all the rotating shafts 122 rotate synchronously.

[0037] Reference Figure 3-Figure 5 The reeling mechanism 2 extends in the same direction as the bottom beam 11, and includes a reeling shaft 21, a contraction structure 22, and a control structure 23. The reeling shaft 21 is rotatably connected to the mounting plate 12, one end of which passes through the mounting plate 12 and is equipped with a first gear 211. The first gear 211 cooperates with the control structure 23 to drive the reeling shaft 21 to rotate. The contraction structure 22 includes a contraction ring 221 slidably sleeved on the reeling shaft 21, a limit plate 222 is sandwiched between the contraction ring 221 and the mounting plate 12, and four sliding grooves 2221 are evenly spaced on the limit plate 222. Four rows of hinge blocks 2211 are arranged at equal intervals along the axial direction on the outer circumference of the shrinking ring 221, and a first connecting rod 223 is hinged on each row of hinge blocks 2211. A winding arc plate 224 is hinged on the other end of the first connecting rod 223. The winding arc plate 224 abuts against the limit plate 222 and has a protruding sliding block inserted into the sliding groove 2221, so that the winding arc plate 224 can move along the sliding groove 2221 under the drive of the sliding block. It can be understood that a hydraulic cylinder is arranged in the winding shaft 21, and the telescopic end of the hydraulic cylinder extends radially and is fixedly connected to the shrinking ring 221 sleeved on the winding shaft 21, driving the shrinking ring 221 to slide on the winding shaft 21.

[0038] The shrinking ring 221 is pushed by the hydraulic cylinder to move axially along the winding shaft 21, driving the first connecting rod 223 hinged on the shrinking ring 221 to move synchronously, and the first connecting rod 223 further drives the winding arc plate 224 to move. Since one end of the winding arc plate 224 is connected to the limit plate 222, the sliding block can only move in the sliding groove 2221, thereby limiting the radial expansion of the winding arc plate 224 driven by the first connecting rod 223. The expanded winding arc plate 224 is used to fix the inner lining arc plate 101.

[0039] Reference Figure 2 , Fig. 9The control structure 23 is used to control the idle winding arc plate 224 to be fixed under the conveying window 121 to ensure the stability of the lining arc plate 101 during conveying. The control structure 23 includes a swing shaft 231, a swing plate 232 and a meshing gear 233. The swing shaft 231 is fixed on the mounting plate 12 and is located above the first gear 211. The swing plate 232 is rotatably sleeved on the swing shaft 231. One end of the swing plate 232 protrudes with a round sleeve that abuts on the mounting plate 121 for cooperating with the fixing structure 3; the other end of the swing plate 232 is connected to the meshing gear 233, and the meshing gear 233 abuts on the mounting plate 121; when one end of the swing plate 232 with the round sleeve is subjected to force, the meshing gear 233 at the other end of the swing plate 232 is driven to abut on the mounting plate 121 with the swing shaft 231 as a fulcrum, so that the meshing gear 233 is disengaged from the first gear 211 of the winding shaft 21, and the first gear 211 drives the winding shaft 21 to stop rotating. Specifically, the meshing gear 233 is also connected to a meshing pulley 234, which corresponds to the center of the meshing gear 233, and the meshing pulley 234 contacts the tensioned belt 123, so that the belt 123 drives the meshing pulley 234 to rotate synchronously, thereby driving the meshing gear 233 to rotate.

[0040] Reference Figure 4-Figure 8 The clamping structure 3 is arranged on the winding mechanism 2, and is used to clamp each inner liner arc plate 101 to prevent the four inner liner arc plates 101 that are spliced ​​and surrounded from falling off due to the centrifugal force when rotating. The clamping structure 3 has a clamping assembly 31, which is arranged in each winding arc plate 224, including a first clamping plate 311 and a locking shaft 312. The first clamping plate 311 is The shape is configured as two vertical sections and one horizontal section, and is located at the end of the winding arc plate 224 away from the limiting disk 222. A corresponding chamber 2241 is provided on the winding arc plate 224 to accommodate the first clamping plate 311 to slide therein; two chambers 2241 are provided, and the open ends extend to the outer arc surface of the winding arc plate 224, one of the chambers 2241 is connected to a sliding channel 2242, and the other chamber 2241 is connected to a connecting channel 2243, and both the sliding channel 2242 and the connecting channel 2243 extend to and penetrate the end close to the limiting disk 222.

[0041] The two vertical sections of the first clamping plate 311 are located in the two chambers 2241 and extend outward, and are inserted into the inner lining arc plate 101 to fix it. One of the vertical sections of the first clamping plate 311 is connected to the second connecting rod 314, and the other vertical section is connected to the third connecting rod 315. One end of the second connecting rod 314 is fixed on one of the vertical sections, and the other end is inserted into the sliding channel 2242. A locking shaft 312 is inserted into the end of the sliding channel 2242 close to the limit plate 222. The locking shaft 312 and the second connecting rod 314 block the two ends of the sliding channel 2242 to form a sealed cavity. The sealed cavity is filled with gas, so that when the first clamping plate 311 moves, the locking shaft 312 can be driven by the gas to move synchronously. It can be understood that an elastic member is provided on the first clamping plate 311. When the inner lining arc plate 101 releases the resistance to the first clamping plate 311, the first clamping plate 311 can return to its original position under the action of the elastic member.

[0042] Furthermore, a semicircular locking groove is provided on the outer circumferential surface of the locking shaft 312, and a matching ball is provided in the locking groove, wherein half of the ball extends into the locking groove to press against the locking shaft 312 for fixation, and the other half of the ball extends to the sliding channel 2242; when the locking shaft 312 moves, the ball is squeezed out of the locking groove, so that the ball releases the locking shaft 312.

[0043] When the second connecting rod 314 moves close to one end of the limit plate 222, the locking shaft 312 moves synchronously and extends out of the sliding channel 2242, and the ball is inserted into the locking groove to clamp the locking shaft 312. The inner lining arc plate 101 passes through the conveying window 121 and slides on the winding arc plate 224, pressing against the first clamping plate 311 and moving toward the end away from the limit plate 222, and the second connecting rod 314 connected to the first clamping plate 311 moves synchronously; and the locking shaft 312 will not move synchronously with the second connecting rod 314 because it is clamped by the ball. At this time, the gas in the sealed chamber is pumped, and then suction is generated on the locking shaft 312. When the inner lining arc plate 101 pushes the first clamping plate 311 to move into place, the suction force on the locking shaft 312 reaches the critical value, and it starts to move, squeezing the ball out of the locking groove, releasing the ball from clamping the locking shaft 312, so that the locking shaft 312 moves into the sliding channel 2242.

[0044] Combination Figure 5In order to stably fix the lining arc plate 101 on the winding arc plate 224, a receiving cavity is provided on one end of the winding arc plate 224 near the limiting plate 222, and the receiving cavity is communicated with the connecting channel 2243. The clamping assembly 31 also includes a second clamping plate 313, which is rotatably arranged in the receiving cavity, and one end of the second clamping plate 313 is connected with a gear to form a swinging end, and the swinging end is hinged to one end of the third connecting rod 315, and the third connecting rod 315 is arranged in the connecting channel 2243 and hinged to the remaining vertical section of the first clamping plate 311. The second clamping plate 313 is horizontally installed in the receiving cavity, and a rack section is provided in the receiving cavity to mesh with the swinging end of the second clamping plate 313, so that the second clamping plate 313 can rotate around the swinging end while moving on the rack section, and the other end of the second clamping plate 313 is turned outside the receiving cavity to clamp the lining arc plate 101.

[0045] When the inner lining arc plate 101 moves against the first clamping plate 311 on the winding arc plate 224, the first clamping plate 311 drives the third connecting rod 315 to move synchronously, and the third connecting rod 315 pulls the swinging end of the second clamping plate 313 to move on the rack segment and swing at the same time, so that the second clamping plate 313 horizontally arranged in the accommodating cavity is swung to a vertical state, and the end of the vertical second clamping plate 313 extends out of the accommodating cavity to clamp the inner lining arc plate 101, so that the inner lining arc plate 101 is stably fixed on the winding arc plate 224.

[0046] Furthermore, the fixing structure 3 is also provided with a conveying assembly 32, which is used to convey the inner lining arc plate 101 passing through the conveying window 121 to a predetermined position. The conveying assembly 32 includes a meshing shaft 321, a bevel gear set 322 and a conveyor belt 323. The meshing shaft 321 is arranged at one end of the winding arc plate 224 close to the limit plate 222. One end of the meshing shaft 321 is arranged in a gear shape and can mesh with the meshing gear 233, and the other end is sleeved with a crank rod 324. The crank rod 324 connects the meshing shaft 321 with the locking shaft 312, so that when the locking shaft 312 moves, the meshing shaft 321 is driven to move synchronously. The bevel gear set 322 has two bevel gears that mesh perpendicularly with each other, one of which is slidably sleeved on the meshing shaft 321, and the other bevel gear has a cylinder protruding from the center, and the cylinder is sleeved with a conveyor belt 323, and the conveyor belt 323 extends in the direction of the first fixing plate 311.

[0047] Reference Figure 7 , Figure 8When the original inner lining arc plate 101 on the winding arc plate 224 is removed, the first clamping plate 311 moves toward the limit plate 222 under the action of the elastic member. At the same time, the second connecting rod 314 moves in the sliding channel 2242, pushing the locking shaft 312 out of the sliding channel 2242, and the third connecting rod 315 pushes the second clamping plate 313 to swing to a horizontal state. The extended locking shaft 312 abuts against the mounting plate 12 and slides, and finally abuts against the circular sleeve of the swing plate 232. The locking shaft 312 rotates with the winding shaft 21 to the bottom of the conveying window 121, and the locking shaft 312 penetrates the corresponding through hole on the mounting plate 12, and abuts against the end of the swing plate 232 away from the swing shaft 231, so that the swing plate 232 rotates around the swing shaft 231, lifting the meshing gear 233 and disengaging it from the first gear 211. The locking shaft 312 can drive the meshing shaft 321 to move synchronously through the crankshaft 324. The meshing shaft 321 also passes through the mounting plate 12 and meshes with the raised meshing gear 233. The meshing gear 233 rotates to drive the meshing shaft 321 to rotate, and the meshing shaft 321 further drives the bevel gear set 322 to rotate. The bevel gear set 322 drives the conveyor belt 323 to move, and the inner liner arc plate 101 is conveyed to a predetermined position.

[0048] Reference Figure 2 , Figure 10-12 The silo mechanism 4 is connected to the rear side of the machine base 1, and is used to store and load the liner arc plates 101. The silo mechanism 4 includes a silo frame 41, a lifting assembly 42, a feeding assembly 43, and a control rod 44. The silo frame 41 is arranged on the side of the mounting plate 12 opposite to the winding mechanism 2 and corresponds to the conveying window 121. The lifting assembly 42 is installed in the silo frame 41, and can drive the stacked liner arc plates 101 to rise and fall, so that the top liner arc plate 101 is conveyed to the position of the conveying window 121, so that the liner arc plate 101 passes through the conveying window 121 and moves to the winding arc plate 224. The feeding assembly 43 is arranged in the silo frame 41, and is used to push the top liner arc plate 101 on the lifting assembly 42 to pass through the conveying window 121. The control rod 44 is disposed on the silo frame 41 to be connected to the control structure 23 , and can control whether the feeding assembly 43 pushes the liner arc plate 101 through the conveying window 121 according to the state change of the control structure 23 .

[0049] The lifting assembly 42 includes a lifting base plate 421, a lifting screw rod 422 and a lifting plate 423. The lifting base plate 421 is fixed to the lower end of the silo frame 41. The four top corners of the lifting base plate 421 are provided with rotatable lifting screw rods 422. The four lifting screw rods 422 extend to the top of the silo frame 41. Each lifting screw rod 422 is connected to one end of the lifting base plate 421 and is connected to a lifting motor, which drives the lifting screw rod 422 to rotate. The lifting plate 423 is slidably arranged on the four lifting screw rods 422. The four top corners of the lifting plate 423 are provided with threaded sleeves that cooperate with the lifting screw rods 422. The threaded sleeves drive the lifting plate 423 to move under the action of the lifting screw rods 422, thereby driving the inner lining arc plate 101 stored on the lifting plate 423 to move synchronously.

[0050] The feeding assembly 43 includes a feeding spindle 431, two follower shafts 432, two feeding screws 433 and a push plate 434. The feeding spindle 431 is arranged at the bottom of the silo frame 41. One end of the feeding spindle 431 close to the mounting plate 12 protrudes out of the silo frame 41 and cooperates with a rotating shaft 122, so that the rotating shaft 122 drives the feeding spindle 431 to rotate synchronously. The two follower shafts 432 are arranged in parallel on both sides of the feeding spindle 431. By arranging synchronous wheels and synchronous belts at the ends of the feeding spindle 431 and the follower shaft 432, the two can rotate synchronously. The two feeding screws 433 are rotatably arranged at the top of the silo frame 41, and they also rotate synchronously with the follower shaft 432 through synchronous wheels and synchronous belts. The push plate 434 is sleeved on two feeding screws 433, and the two feeding screws 433 can drive the push plate 434 to move unidirectionally toward the direction close to the conveying window 121. A push rod is hinged at the bottom of the push plate 434 to push the inner lining arc plate 101 to move, and the push rod can swing from a vertical state to a direction close to the mounting plate 12.

[0051] In order to enable the push plate 434 to reciprocate along the feed screw 433 and repeatedly push the liner arc plate 101 through the conveying window 121, the feed assembly 43 also includes two reversing assemblies 435, which are arranged at both ends of the push plate 434 and correspond to the two feed screws 433. Each reversing assembly 435 includes a reversing rod 4351, a reversing block 4352 and two reversing blocks 4353. The reversing rod 4351 is arranged on the push plate 434 and is located above the feed screw 433. One end of the reversing rod 4351 is arranged in a shape that matches the feed screw 433, inserted into the push plate 434 and matched with the feed screw 433, so as to drive the push plate 434 to move along the feed screw 433. One end of the reversing rod 4351 outside the push plate 434 is connected to a baffle, and a first spring is arranged on the baffle to connect with the push plate 434. The first spring is sleeved on the reversing rod 4351 to keep the reversing rod 4351 in cooperation with the feed screw 433. The reversing block 4352 is slidably arranged on the push plate 434 and is located below the baffle. A convex block is formed on the top surface of the reversing block 4352, which can resist the baffle to rise, drive the reversing rod 4351 to rise synchronously, and break away from the cooperation with the feed screw 433, so that the push plate 434 can slide freely on the feed screw 433. Two reversing blocks 4353 are arranged on the top surface of the silo frame 41, close to the two ends of each feeding screw 433, and the two reversing blocks 4353 extend into the silo frame 41 to resist the reversing block 4352 that moves with the push plate 434 to the corresponding one, so that it slides on the push plate 434. When the reversing block 4352 drives the protrusion to slide below the baffle, the protrusion lifts the baffle, so that the reversing rod 4351 is separated from the cooperation with the feeding screw 433. When the protrusion slides outside the baffle, the baffle is pulled down by the first spring, driving the reversing rod 4351 to cooperate with the feeding screw 433 again. It can be understood that a return spring is arranged between the push plate 434 and the silo frame 41, and the return spring can restore the push plate 434 to its original position after moving.

[0052] When the feeding assembly 43 pushes the inner lining arc plate 101 to feed the material to the winding mechanism 2, the reversing block 4352 is located outside the baffle, and the baffle drives the reversing rod 4351 to descend under the action of the first spring and cooperate with the feeding screw 433. The feeding screw 433 drives the pushing plate 434 to move toward the end close to the conveying window 121, and the pushing plate 434 drives the reversing block 4352 to move synchronously. The push rod hinged at the bottom of the pushing plate 434 is in a vertical state, which is against the rear side of the inner lining arc plate 101 and pushes it through the conveying window 121. When approaching one end of the conveying window 121, the reversing block 4353 at this end blocks the reversing block 4352 and moves synchronously with the push plate 434. The reversing block 4352 slides on the push plate 434 to the bottom of the baffle, so that the protrusion of the reversing block 4352 hits the baffle to drive the reversing rod 4351 to rise, and the cooperation between the reversing rod 4351 and the feeding rod 433 is released, so that the push plate 434 can slide back to the original position under the action of the reset spring. The push rod hinged to the push plate 434 will be blocked by the rising inner lining arc plate 101 when moving in the reverse direction, so that the push rod swings toward the conveying window 121, slides against the top surface of the inner lining arc plate 101, and then hangs down again to the vertical state after passing the inner lining arc plate 101, waiting for the next push.

[0053] Reference Fig.11 , Fig.12 The control rod 44 is rotatably arranged on the outside of the silo frame 41, and can control the feeding assembly 43 to push the liner arc plate 101 through the conveying window 121 when the vacant winding arc plate 224 is located below the conveying window 121. The end of the control rod 44 close to the mounting plate 12 extends to the lower end of the control structure 23, and is connected to the end of the swing plate 232 away from the meshing gear 233. The swing plate 232 is pushed down by the locking shaft 312 to drive the control rod 44 to rotate downward synchronously. A limit rod 441 is arranged in the middle of the control rod 44, which can resist the push plate 434 from being pulled back to the original position by the reset spring, so that the push plate 434 is close to returning to the original position when it is resisted by the limit rod 441.

[0054] When the idle winding arc plate 224 rotates to the bottom of the conveying window 121, the locking shaft 312 passes through the mounting plate 12 to press against the swing plate 232 to rotate, and the end of the swing plate 232 away from the meshing gear 233 moves downward, driving the control rod 44 to move synchronously, and the limit rod 441 connected to the control rod 44 moves downward synchronously, releasing the resistance to the push plate 434, and the push plate 434 is pulled back to its original position by the reset spring. When the push plate 434 is in its original position, the reversing block 4352 sliding on the push plate 434 is pushed out of the baffle by the reversing block 4353, and the baffle drives the reversing rod 4351 to descend and cooperate with the feeding screw 433, and the rotating feeding screw 433 drives the push plate 434 to move.

[0055] The implementation principle of the steel strip winding machine in the embodiment of the present application is as follows:

[0056] A plurality of inner lining arc plates 101 are stacked in the silo mechanism 4, and the silo mechanism 4 is connected to the mounting plate 12, so that the feeding main shaft 431 is sleeved with a rotating shaft 122. Then the first motor 13 is started, and the first motor 13 drives the pulleys and the meshing pulley 234 on the rotating shaft 122 to rotate synchronously through the belt 123. The meshing pulley 234 is driven by the tensioning force of the belt 123 to mesh with the meshing gear 233 and the first gear 211, driving the winding shaft 21 to rotate, and then driving the idle winding arc plate 224 to rotate to the bottom of the conveying window 121. The feeding main shaft 431 rotates synchronously with the sleeved rotating shaft 122, driving the follower shaft 432 to rotate, and then driving the feeding screw 433 to rotate.

[0057] The locking shaft 312 in the winding arc plate 224 passes through the mounting plate 12, presses against the swing plate 232 to rotate around the swing shaft 231, and moves synchronously with the meshing shaft 321 connected to the locking shaft 312 through the crank 324, passing through the mounting plate 12. The end of the swing plate 232 pressed against by the locking shaft 312 rotates downward, and the other end drives the meshing gear 233 and the meshing pulley 234 to rotate upward, and the meshing gear 233 meshes with the meshing shaft 321, driving the meshing shaft 231 to rotate synchronously. A bevel gear sleeved on the meshing shaft 321 rotates synchronously, and is transmitted to another bevel gear of the bevel gear set, thereby driving the conveyor belt 323 on the cylinder to move.

[0058] The control rod 44 rotates downward with the swing plate 232, driving the limit rod 441 to rotate synchronously, releasing the resistance to the push plate 434, so that the reset spring pulls the push plate 434 to return to its original position. At this time, the reversing block 4352 sliding on the push plate 434 is resisted by the reversing block 4353, sliding away from the resistance to the baffle, and the baffle drives the reversing rod 4351 to descend and cooperate with the feeding screw 433 under the action of the first spring, and the rotating feeding screw 433 drives the push plate 434 to move in one direction. The push rod hinged at the lower end of the push plate 434 pushes the inner lining arc plate 101 through the conveying window 121 to move onto the winding arc plate 224. The conveyor belt 223 on the winding arc plate 224 drives the winding arc plate 224 to move further. The moving winding arc plate 224 pushes against the first clamping plate 311 and moves synchronously. The movement of the first clamping plate 311 drives the second connecting rod 314 to pump the gas in the sliding channel 2242, generating suction force on the locking shaft 312. At the same time, the movement of the first clamping plate 311 drives the third connecting rod 315 to move synchronously. The third connecting rod 315 pulls the second clamping plate 313 to swing to an upright state, and cooperates with the first clamping plate 311 to fix the two ends of the inner lining arc plate 101. When the suction force in the sliding channel 2242 exceeds the critical value, the locking shaft 312 is pulled back into the sliding channel 2242, and the support against the swing plate 232 is withdrawn. The swing plate 232 rotates around the swing shaft 231, driving the meshing pulley 234 and the control rod 44 to return to their original positions, so that the meshing pulley 234 drives the meshing gear 233 to drive the first gear 211 to rotate again; and the control rod 44 drives the limit rod 441 to rotate, and again supports the material return plate 434 to return to its original position, waiting for the next empty winding arc plate 224 to rotate to the bottom of the conveying window 121 and repeat the above actions.

[0059] When the steel strip is completely rolled up on the inner sleeve formed by the inner lining arc plate 101, the shrinking ring 221 moves and drives the winding arc plate 224 to shrink through the first connecting rod 223, so that the first clamping plate 311 and the second clamping plate 313 release the fixation on the inner lining arc plate 224, and the first clamping plate 311 is pushed back to its original position by the elastic part. After waiting for the steel coil to be taken away, the shrinking ring 221 is unfolded again and the above actions are repeated.

[0060] The steel strip winder provided by the present invention uses spliced ​​inner lining arc plates to surround a complete inner lining sleeve, which is convenient for the installation and storage of the inner lining sleeve. The inner lining arc plate is clamped by the winding arc plate, which improves the stability of the inner lining arc plate during rotation. The designed silo mechanism can automatically feed the empty winding arc plate, which greatly improves the smoothness of the equipment operation, effectively reduces the difficulty of operating the equipment, and ensures the personal safety of the staff.

[0061] The above-described embodiments only express the implementation methods of the present invention, but they cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
