Description

Technical Field

[0001] The present application relates to the field of steel strip processing, and in particular to a high-efficiency paper sleeve device. Background Art

[0002] Steel strip is a narrow and long steel plate, which is usually supplied in rolls. After the steel strip is processed, it needs to be rolled using a winder. Before rolling the steel strip, it is necessary to install the paper tube on the winding roller of the winder, and then start the winder to drive the winding roller to rotate. The rotation of the winding roller drives the paper tube to rotate, thereby rolling the steel strip.

[0003] In the related art, it is difficult to manually put the paper tube on the winding roller due to the large mass of the paper tube. Usually, a paper tube device is used to put the paper tube on the winding roller. The paper tube device generally includes a frame and a clamping mechanism. The clamping mechanism is slidably arranged on the frame, and a driving mechanism for driving the clamping mechanism to slide is arranged on the frame. During operation, the paper tube is transported to the clamping mechanism, and then the paper tube is clamped by the clamping mechanism and the end of the paper tube is aligned with the winding roller. Then, the driving mechanism is used to drive the clamping mechanism to slide so that the paper tube is put on the winding roller. After the paper tube is put on the winding roller, the clamping mechanism is released, and the driving mechanism drives the clamping mechanism to leave. After the steel strip is wound, the steel strip is unwound by the crane, and then the next paper tube is put on the winding roller by the paper tube device, and the above operation process is repeated in sequence.

[0004] However, since the mass of the paper tubes is relatively large and a large number of paper tubes need to be processed during mass production, workers are required to continuously move the paper tubes to the clamping mechanism, which results in high labor intensity and low production efficiency. Summary of the invention

[0005] In order to reduce the labor intensity of workers and improve production efficiency, the present application provides a high-efficiency paper tube sleeve device.

[0006] The present application provides an efficient paper sleeve device that adopts the following technical solution:

[0007] A highly efficient paper tube device comprises a frame, a first clamping mechanism, the first clamping mechanism is arranged on the frame to slide along the axial direction of a winding roller, and the first clamping mechanism is arranged on the frame to slide along the vertical direction, the frame is provided with a first sliding assembly driving the first clamping mechanism to slide along the axial direction of the winding roller and a second sliding assembly driving the first clamping mechanism to slide along the vertical direction, the first clamping mechanism comprises a first clamping jaw, a second clamping jaw and a first driving member, a first clamping opening for clamping a paper tube is formed between the first clamping jaw and the second clamping jaw, and the first driving member is used to control The first clamping jaw and the second clamping jaw are controlled to open or clamp, a discharging mechanism for discharging paper tubes one by one is arranged on one side of the frame, a storage plate for receiving paper tubes is arranged on one side of the discharging mechanism, the cross-section of the storage plate is arc-shaped, the height in the middle of the storage plate is lower than the height on both sides of the storage plate, the length direction of the storage plate is parallel to the winding roller, the storage plate is slidingly arranged along the length direction of the winding roller, and a third sliding component for driving the storage plate to slide is arranged on one side of the discharging mechanism, and the axis of the winding roller is located in a vertical plane passing through the lowest point of the storage plate and along the length direction of the storage plate.

[0008] By adopting the above technical solution, during operation, the paper tubes are output one by one by using the discharging mechanism. After the paper tubes come out of the discharging port, they fall onto the storage plate. Under the action of gravity, the paper tubes will fall into the middle position of the storage plate, thereby positioning the paper tube so that the axis of the paper tube and the axis of the winding roller are located in the same vertical plane. Then, the third sliding assembly is used to drive the storage plate to move, thereby driving the paper tube to move. When the paper tube is located directly below the first clamping mechanism, the storage plate stops moving, and the second sliding assembly is started to move the first jaw and the second jaw downward. At the same time, the first driving member is used to control the first jaw and the second jaw to open. After the paper tube is located in the first clamping port, the first driving member is used to control the first jaw and the second jaw to clamp, thereby clamping the paper tube. Then, the second sliding assembly is started to drive the first jaw and the second jaw to move upward, thereby making the paper tube Move upward, when the axis of the paper tube and the axis of the winding roller are at the same height, close the second sliding assembly. Since the axis of the paper tube and the axis of the winding roller are in the same vertical plane, the paper tube and the winding roller are coaxial at this time. Then start the first sliding assembly to drive the first clamping mechanism to move in the direction close to the winding roller, thereby driving the paper tube to move in the direction close to the winding roller, so that the paper tube is sleeved on the winding roller. After the paper tube is sleeved on the winding roller, the first clamping jaw and the second clamping jaw are released, and then the first sliding assembly drives the first clamping mechanism to move in the direction away from the winding roller. When the number of windings of the steel belt on the paper tube reaches the specified value, the steel belt is cut off by a cutting machine, and then the paper tube with the steel belt is removed by a crane. Then start the third sliding assembly to reset the storage plate, and then use the discharging mechanism to output the next paper tube, and repeat the above process in sequence. The whole process does not require manual handling of the paper tube, which effectively reduces the labor intensity of workers and improves production efficiency.

[0009] Optionally, the discharging mechanism includes a storage box for storing paper rolls, wherein the storage box is located on one side of the storage plate, and the storage box is slidably arranged in a vertical direction toward the side wall of the storage plate, so that a discharging port is formed on the side of the storage plate, and the height of the highest point of the storage plate is less than or equal to the height of the lowest point of the discharging port. A fourth sliding component is arranged on the storage box to drive the storage box to slide toward the side wall of the storage plate, and the inner bottom surface of the storage box is inclined, and the height of the inner bottom surface of the storage box gradually increases in the direction away from the discharging port.

[0010] By adopting the above technical solution, the fourth sliding component is used to drive the storage box to slide upward toward the side wall of the storage plate, so that the discharge port is opened, and then the paper tubes in the storage box will roll out from the discharge port under the action of gravity. After rolling out, the paper tubes will fall onto the storage plate on one side. At the same time, after a paper tube rolls out, the fourth sliding component drives the storage box to move downward toward the side wall of the storage plate, thereby preventing subsequent paper tubes from rolling out, and outputting the paper tubes one by one. The structure is simple.

[0011] Optionally, the first jaw and the second jaw are both arc-shaped, and when the first clamping mechanism clamps the paper tube, the distance between the top of the first jaw and the top of the second jaw is smaller than the diameter of the paper tube, and the distance between the bottom of the first jaw and the bottom of the second jaw is smaller than the diameter of the paper tube.

[0012] By adopting the above technical solution, when the first clamp and the second clamp grab the paper tube, the arc-shaped structure will generate an upward force on the paper tube, so that the paper tube enters the first clamping opening. After the paper tube is clamped, since the distance between the bottom end of the first clamp and the bottom end of the second clamp is smaller than the diameter of the paper tube, the first clamp and the second clamp can support the paper tube, thereby reducing the possibility of the paper tube falling out of the clamping opening, and the structure is reasonable.

[0013] Optionally, the first clamping mechanism further includes a first plate, a second plate and a third plate, the first plate and the second plate are both vertically arranged, a horizontal first fixed plate is arranged on the first plate, a first pressing plate is hingedly connected to the bottom end of the first plate, a top end of the first clamping jaw is hingedly connected to the bottom end of the first plate and is fixedly connected to an end of the first pressing plate close to the first plate, a horizontal second fixed plate is arranged on the second plate, a second pressing plate is hingedly connected to the bottom end of the second plate and is fixedly connected to an end of the second pressing plate close to the second plate, and the first driving member includes a first cylinder and a second Cylinder, one end of the cylinder body of the first cylinder facing away from the piston rod is hinged to the first fixed plate, one end of the piston rod of the first cylinder facing away from the cylinder body is hinged to the first pressure plate, one end of the cylinder body of the second cylinder facing away from the piston rod is hinged to the second fixed plate, one end of the piston rod of the second cylinder facing away from the cylinder body is hinged to the second pressure plate, the third plate is horizontally arranged and arranged in a direction perpendicular to the length of the winding roller, two ends of the third plate are fixedly connected to the first plate and the second plate respectively, the first sliding assembly is used to drive the third plate to move axially along the winding roller, and the second sliding assembly is used to drive the third plate to move in the vertical direction.

[0014] By adopting the above technical solution, when clamping the paper tube, the second sliding assembly is used to drive the third plate to move downward, and the third plate drives the first plate and the second plate to move downward, thereby driving the first clamping claw and the second clamping claw to move downward, and at the same time, the first cylinder and the second cylinder are started, so that the piston rods of the first cylinder and the second cylinder are contracted, thereby driving the first pressing plate and the second pressing plate to rotate upward, so that the first clamping claw and the second clamping claw are opened, and when the paper tube is located in the first clamping opening, the piston rods of the first cylinder and the second cylinder are extended, thereby driving the first pressing plate and the second pressing plate to rotate downward, so that the first clamping claw and the second clamping claw are clamped, thereby clamping the paper tube, and after the paper tube is clamped, the second sliding assembly is used. The sliding assembly drives the third plate to move upward, thereby driving the paper roll to move upward. When the axis of the paper roll and the axis of the winding roller are at the same height, the second sliding assembly is closed, and then the first sliding assembly is used to drive the third plate to move in the direction close to the winding shaft, thereby driving the paper roll to move in the direction close to the winding shaft, and then the paper roll is sleeved on the winding shaft. After the paper roll is sleeved on the winding shaft, the piston rods of the first cylinder and the second cylinder are contracted, driving the first pressure plate and the second pressure plate to rotate upward, so that the first clamp and the second clamp are opened, and then the first sliding assembly is used to drive the third plate to move in the direction away from the winding shaft, so that the first clamping mechanism is reset. The structure is simple and the operation is convenient.

[0015] Optionally, an extrusion mechanism is provided on the third plate, and the extrusion mechanism includes a third cylinder and an extrusion plate. The third cylinder is provided on the third plate with a piston rod vertically downward, and the extrusion plate is horizontally provided on the piston rod of the third cylinder, and the extrusion plate is parallel to the winding roller. A first slide groove with an arc-shaped cross-section is provided on the lower surface of the extrusion plate along the length direction of the winding roller, and the heights on both sides of the first slide groove are lower than the height in the middle of the first slide groove.

[0016] By adopting the above technical solution, when the first clamp and the second clamp are in the process of clamping the paper tube, the paper tube will collide with the first clamp and the second clamp, and the paper tube may be deformed. The third cylinder is used to drive the squeezing plate to move downward, so that the squeezing plate squeezes the paper tube downward. After the paper tube is subjected to the force of the squeezing plate, it will tend to expand in the horizontal direction, thereby reducing the possibility of deformation of the paper tube. The arc-shaped first slide groove increases the contact area between the squeezing plate and the paper tube, thereby reducing the pressure on the paper tube and reducing the possibility of the paper tube being squeezed and deformed by the squeezing plate.

[0017] Optionally, the extrusion mechanism also includes a connecting plate, a first positioning shaft, a second positioning shaft, a first spring and a second spring, the connecting plate is fixedly connected to the piston rod of the third cylinder, the first positioning shaft and the second positioning shaft are both vertically slidably arranged on the connecting plate, the first positioning shaft and the second positioning shaft both pass through the connecting plate upward, the extrusion plate is fixedly connected to the bottom end of the first positioning shaft and to the bottom end of the second positioning shaft, the first spring is sleeved on the first positioning shaft and the two ends of the first spring are respectively connected to the connecting plate and the extrusion plate, the second spring is sleeved on the second positioning shaft and the two ends are respectively connected to the connecting plate and the extrusion plate.

[0018] By adopting the above technical solution, the movement of the piston rod of the cylinder drives the connection plate to move, and the connection plate drives the extrusion plate to move through the first spring and the second spring. When the extrusion plate is in close contact with the paper tube, the cylinder is closed, and the elastic force of the first spring and the second spring is transmitted to the paper tube, thereby squeezing the paper tube. If the cylinder is not closed in time or the piston rod still moves forward a certain distance after the cylinder is closed, the first spring and the second spring will continue to be compressed, but the extrusion plate will not continue to move downward, thereby effectively reducing the possibility of the paper tube being squeezed and deformed.

[0019] Optionally, threads are provided on the side walls of the first positioning shaft and the second positioning shaft, a first limiting plate is threadedly connected to the first positioning shaft, the first limiting plate is located above the connecting plate and pressed against the connecting plate, and a second limiting plate is threadedly connected to the second positioning shaft, the second limiting plate is located above the connecting plate and pressed against the connecting plate.

[0020] By adopting the above technical solution, the first limit plate and the second limit plate are used to adjust the distance between the connecting plate and the extrusion plate, thereby adjusting the original length of the first spring and the second spring, so that the initial elastic force of the first spring and the second spring can be adjusted. If the first spring and the second spring are in a stretched state and the elastic force generated is the same as the total gravity of the extrusion plate, the first positioning axis and the second positioning axis, the force generated when the extrusion plate contacts the paper tube is zero. As the connecting plate continues to move, the first spring and the second spring are compressed, so that the extrusion plate generates a force on the paper tube. This process is relatively smooth, which effectively reduces the possibility of the paper tube being squeezed and deformed.

[0021] Optionally, a second clamping mechanism is provided on the frame, and the second clamping mechanism is slidably provided on the frame in the vertical direction and is slidably provided on the frame along the axial direction of the winding roller. A fifth sliding assembly for driving the second clamping mechanism to slide along the axial direction of the winding roller and a sixth sliding assembly for driving the second clamping mechanism to slide along the vertical direction are provided on the frame. A squeezing roller is clamped in the second clamping mechanism. When the axis of the squeezing roller and the axis of the winding roller are at the same height, the squeezing roller is coaxial with the winding roller, and there is an interference fit between the squeezing roller and the inner wall of the paper tube.

[0022] By adopting the above technical scheme, after the first clamping mechanism clamps the paper tube, the sixth sliding assembly is used to drive the second clamping mechanism to move in the vertical direction, so that the squeezing roller and the paper tube are coaxial, and then the fifth sliding assembly is used to drive the second clamping mechanism to move in the direction close to the paper tube, so that the squeezing roller is inserted into the paper tube. Since there is an interference fit between the squeezing roller and the paper tube, the entire paper tube will tend to expand in the radial direction, thereby restoring the deformed part of the paper tube, and then the squeezing mechanism is used to squeeze the paper tube, so as to trim the outer side wall of the paper tube, and then the first sliding assembly is used to drive the paper tube and the squeezing roller to move in the direction close to the winding roller. After the squeezing roller contacts the winding roller, it will gradually be pushed out by the winding roller, and then the fifth sliding assembly is started to make the second clamping mechanism close to the winding roller, and then the second clamping mechanism is used to clamp the squeezing roller. In the process of the squeezing roller being pushed out, the fifth sliding assembly is used to drive the second clamping mechanism to move in the direction away from the winding roller, thereby resetting the squeezing roller.

[0023] Optionally, a bracket is provided below the first clamping mechanism, and a rotating mechanism is provided on the bracket, and the rotating mechanism includes a first motor and a second motor, and the first motor and the second motor are both slidably provided on the bracket along the length direction of the winding roller, and a seventh sliding component is provided on the bracket for driving the first motor and the second motor to approach or move away from each other, the output shaft of the first motor and the output shaft of the second motor are coaxial, and the output shafts of the first motor and the second motor are both located between the first motor and the second motor, the axis of the output shaft of the first motor, the axis of the output shaft of the second motor and the axis of the winding roller are located in the same vertical plane, the output shaft of the first motor is coaxially fixedly connected with the first rotating shaft, and the side wall of the first rotating shaft is A first convex strip is provided, and the output shaft of the second motor is coaxially fixedly connected with the second rotating shaft, and a second convex strip is provided on the side wall of the second rotating shaft.

A first plugging groove along the length direction of the squeezing roller is provided on the side wall of the first hole, and the first plugging groove passes through the end of the squeezing roller away from the second hole. A second plugging groove along the length direction of the squeezing roller is provided on the side wall of the second hole, and the second plugging groove passes through the end of the squeezing roller away from the first hole. When the first rotating shaft and the second rotating shaft are respectively inserted into the first hole and the second hole, the first convex strip is plugged into and matched with the first plugging groove, and the second convex strip is plugged into and matched with the second plugging groove.

[0024] By adopting the above technical solution, after the squeezing roller is inserted into the paper roll, the fifth sliding assembly is used to drive the paper roll and the squeezing roller to move along the length direction of the winding roller, so that the paper roll and the squeezing roller are located between the first motor and the second motor in the horizontal direction, and then the sixth sliding assembly is used to drive the paper roll and the squeezing roller to move downward. When the squeezing roller is coaxial with the output shaft of the first motor, the paper roll and the squeezing roller stop moving, and then the seventh sliding assembly is used to drive the first motor and the second motor to approach each other, so that the first rotating shaft is inserted into the first hole, the first convex strip is inserted into the first plug-in slot, the second rotating shaft is inserted into the second hole, and the second convex strip is inserted into the second plug-in slot, so that The squeezing roller can be fully inserted into the paper tube, and then the first driving member is used to open the first clamp and the second clamp, and then the first motor and the second motor are started to drive the squeezing roller to rotate, and the rotation of the squeezing roller drives the paper tube to rotate, so that the side walls of the paper tube can be squeezed by the squeezing mechanism, thereby trimming the entire outer side wall of the paper tube, and then the first motor and the second motor are closed, and then the first driving member is used to make the first clamp and the second clamp clamp the paper tube, and the seventh sliding assembly is used to drive the first motor and the second motor to move away from each other, so that the first motor and the second motor leave the squeezing roller, and then the second sliding assembly is used to drive the squeezing roller and the paper tube to rise, so that the paper tube and the winding roller are coaxial.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. During operation, the paper tubes are discharged one by one by using the discharging mechanism. After the paper tubes come out of the discharging port, they fall onto the storage plate. Under the action of gravity, the paper tubes will fall into the middle position of the storage plate, thereby positioning the paper tubes so that the axis of the paper tubes and the axis of the winding roller are located in the same vertical plane. Then the third sliding assembly is used to drive the storage plate to move, thereby driving the paper tube to move. When the paper tube is located directly below the first clamping mechanism, the storage plate stops moving, and the second sliding assembly is started to move the first jaw and the second jaw downward. At the same time, the first driving member is used to control the first jaw and the second jaw to open. After the paper tube is located in the first clamping port, the first driving member is used to control the first jaw and the second jaw to clamp, thereby clamping the paper tube. Then the second sliding assembly is started to drive the first jaw and the second jaw to move upward, thereby making the paper tube Move upwards. When the axis of the paper tube and the axis of the winding roller are at the same height, close the second sliding assembly. Since the axis of the paper tube and the axis of the winding roller are in the same vertical plane, the paper tube and the winding roller are coaxial at this time. Then start the first sliding assembly to drive the first clamping mechanism to move in the direction close to the winding roller, thereby driving the paper tube to move in the direction close to the winding roller, so as to sleeve the paper tube on the winding roller. After the paper tube is sleeved on the winding roller, the first clamping jaw and the second clamping jaw are released, and then the first sliding assembly drives the first clamping mechanism to move in the direction away from the winding roller. When the number of windings of the steel belt on the paper tube reaches the specified value, use a cutting machine to cut off the steel belt, and then use a crane to remove the paper tube with the steel belt wound on it. Then start the third sliding assembly to reset the storage plate, and then use the discharging mechanism to output the next paper tube, and repeat the above process in sequence. The entire process does not require manual handling of paper tubes, which effectively reduces the labor intensity of workers and improves production efficiency.

[0029] 2. When the first clamp and the second clamp grab the paper tube, the arc-shaped structure will generate an upward force on the paper tube, so that the paper tube enters the first clamping opening. After the paper tube is clamped, since the distance between the bottom end of the first clamp and the bottom end of the second clamp is smaller than the diameter of the paper tube, the first clamp and the second clamp can support the paper tube, reducing the possibility of the paper tube falling out of the clamping opening, and the structure is reasonable;

[0030] 3. After the squeezing roller is inserted into the paper tube, the fifth sliding assembly is used to drive the paper tube and the squeezing roller to move along the length direction of the winding roller, so that the paper tube and the squeezing roller are located between the first motor and the second motor in the horizontal direction, and then the sixth sliding assembly is used to drive the paper tube and the squeezing roller to move downward. When the squeezing roller is coaxial with the output shaft of the first motor, the paper tube and the squeezing roller stop moving. Then the seventh sliding assembly is used to drive the first motor and the second motor to approach each other, so that the first rotating shaft is inserted into the first hole, the first convex strip is inserted into the first plug-in groove, the second rotating shaft is inserted into the second hole, and the second convex strip is inserted into the second plug-in groove, so that the squeezing roller can be completely inserted into the paper tube. Then the first driving member is used to open the first clamping jaw and the second clamping jaw, and then the first motor and the second motor are started to drive the squeezing roller to rotate. The rotation of the squeezing roller drives the paper tube to rotate, so that the side walls of the paper tube can be squeezed by the squeezing mechanism, thereby trimming the entire outer side wall of the paper tube.

[0058] Reference Figure 7 and Figure 8 When the first rotating shaft 741 and the second rotating shaft 751 are respectively inserted into the first hole 62 and the second hole 63 , the first protruding strip 742 is plugged into and matched with the first inserting groove 621 , and the second protruding strip 752 is plugged into and matched with the second inserting groove 631 .

[0059] The implementation principle of an efficient paper tube sleeve device in an embodiment of the present application is as follows: when working, the two fourth air cylinders 24 are used to drive the first side wall 321 to slide upward, so that the discharge port 322 is opened, and then the paper tubes in the storage box 32 will roll out of the discharge port 322 under the action of gravity. After the paper tubes roll out, the two fourth air cylinders 24 drive the first side wall 321 to move downward, so that the discharge port 322 is closed, thereby preventing the remaining paper tubes in the storage box 32 from rolling out, and outputting the paper tubes one by one.

[0060] After the paper roll falls onto the storage plate 332, it will fall to the middle position of the storage plate 332, i.e., the lowest position of the storage plate 332, under the action of gravity. At this time, the axis of the paper roll and the axis of the winding roller 13 are located in the same vertical plane, and then the third driving motor 232 is started to drive the third lead screw 231 to rotate, and the rotation of the third lead screw 231 drives the storage block 331 to move along the length direction of the mounting plate 12, and the storage block 331 drives the storage plate 332 to move along the length direction of the mounting plate 12, thereby driving the paper roll to move along the length direction of the mounting plate 12. At the same time, the first driving motor 212 is started to drive the first lead screw 211 to rotate, and the rotation of the first lead screw 211 drives the first connecting block 14 to move along the length direction away from the winding roller 13, and the first connecting block 14 drives the first lifting cylinder 22 to move along the length direction away from the winding roller 13, and the first lifting cylinder 22 drives the first clamping mechanism 4 to move along the length direction away from the winding roller 13, thereby making the first clamping mechanism 4 and the paper roll close to each other along the length direction of the mounting plate 12.

[0061] When the paper tube moves to the right below the first clamping mechanism 4, the first drive motor 212 and the third drive motor 232 stop rotating, and then the piston rod of the first lifting cylinder 22 extends to drive the third plate 45 to move downward, and the third plate 45 drives the first plate 43 and the second plate 44 to move downward, and the first plate 43 and the second plate 44 respectively drive the first clamping jaw 41 and the second clamping jaw 42 to move downward, and at the same time, the piston rods of the first cylinder 461 and the second cylinder 462 contract, thereby driving the first pressing plate 432 and the second pressing plate 442 to rotate upward, so that the first clamping jaw 41 and the second clamping jaw 42 are opened, and when the paper tube is located in the first clamping opening, The piston rods of the first cylinder 461 and the second cylinder 462 are extended, thereby driving the first pressure plate 432 and the second pressure plate 442 to rotate downward, so that the first clamping jaw 41 and the second clamping jaw 42 are clamped. Since the first clamping jaw 41 and the second clamping jaw 42 are arc-shaped structures, an upward force is exerted on the paper tube during the clamping process, so that the paper tube enters the first clamping port. After the paper tube is clamped, since the distance between the bottom end of the first clamping jaw 41 and the bottom end of the second clamping jaw 42 is smaller than the diameter of the paper tube, the first clamping jaw 41 and the second clamping jaw 42 can support the paper tube, thereby reducing the possibility of the paper tube falling out of the clamping port.

[0062] Then the piston rod of the first lifting cylinder 22 contracts to drive the paper tube to move upward. When the axis of the paper tube is at the same height as the axis of the squeezing roller 61, the piston rod of the first lifting cylinder 22 stops moving. Then the first drive motor 212 and the fifth drive motor 252 are started to respectively drive the first lead screw 211 and the fifth lead screw 251 to rotate, so that the first connecting block 14 and the second connecting block 15 are close to each other. The first connecting block 14 and the second connecting block 15 respectively drive the first clamping mechanism 4 and the second clamping mechanism 6 to approach each other, so that the paper tube and the squeezing roller 61 are close to each other, and then the squeezing roller 61 is inserted into the paper tube. Since the squeezing roller 61 and the paper tube are in an interference fit, the entire paper tube will tend to expand radially, thereby restoring the deformed part of the paper tube.

[0063] After the squeezing roller 61 is inserted into the paper tube, the second clamping mechanism 6 releases the squeezing roller 61, and then the first driving motor 212 drives the first lead screw 211 to rotate in the opposite direction, so that the paper tube and the squeezing roller 61 move away from the second clamping mechanism 6. When the paper tube with the squeezing roller 61 inserted is located between the first motor 74 and the second motor 75 along the length direction of the mounting plate 12, the second lifting cylinder 26 drives the paper tube to move downward. When the first hole 62 and the first rotating shaft 741 are coaxial, the piston rod of the second lifting cylinder 26 stops moving, so that the paper tube stops moving. Then, the seventh driving motor 271 is started to drive the seventh lead screw 272 to rotate, so that the first slider 71 and the second slider 72 are close to each other, thereby driving the first motor 74 and the second motor 75 to be close to each other, so that the first rotating shaft 741 is inserted into the first hole 62, the first convex strip 742 is inserted into the first plug-in groove 621, the second rotating shaft 751 is inserted into the second hole 63, and the second convex strip 752 is inserted into the second plug-in groove 631. In this process, the squeezing roller 61 can be pushed to move relative to the paper tube, so that the squeezing roller 61 is completely inserted into the paper tube.

[0064] Then the piston rod of the third cylinder 51 extends to drive the connecting plate 52 to move downward, and the connecting plate 52 drives the squeezing plate 53 to move downward through the first positioning shaft 54 ​​and the second positioning shaft 55 until the squeezing plate 53 is tightly against the supporting paper tube, and then the third cylinder 51 is closed, and then the piston rod of the first cylinder 461 and the piston rod of the second cylinder 462 are contracted, driving the first pressing plate 432 and the second pressing plate 442 to rotate upward, so that the first clamping jaw 41 and the second clamping jaw 42 are opened, and then the first motor 74 and the second motor 75 are started to drive the squeezing roller 61 to rotate, and the squeezing roller 61 drives the paper tube to rotate, so that the entire outer side wall of the paper tube can be in close contact with the squeezing plate 53, thereby trimming the entire outer side wall of the paper tube.

[0065] After the trimming is completed, the first motor 74 and the second motor 75 are turned off, and the piston rod of the first cylinder 461 and the piston rod of the second cylinder 462 are extended, driving the first pressure plate 432 and the second pressure plate 442 to rotate downward, so that the first clamp 41 and the second clamp 42 are clamped, and then the seventh drive motor 271 is started to drive the seventh screw 272 to rotate in the opposite direction, so that the first motor 74 and the second motor 75 leave the squeezing roller 61.

[0066] Then the piston rod of the second lifting cylinder 26 contracts and drives the first clamping mechanism 4 to move upward, thereby driving the paper roll upward. When the axis of the paper roll and the axis of the winding roller 13 are at the same height, the paper roll stops moving. Since the axis of the paper roll and the axis of the winding roller 13 are located in the same vertical plane, the paper roll and the winding roller 13 are coaxial at this time. Then the first driving motor 212 is started to drive the first screw rod to rotate, and the first screw rod drives the first connecting block 14 to move in the direction close to the winding roller 13. The first connecting block 14 drives the first clamping mechanism 4 to move close to the winding roller 13. The paper roll 61 is moved in the direction of the winding roll 13, so that the paper roll moves toward the winding roll 13, thereby the winding roll 13 is inserted into the paper roll. In the process of the paper roll being sleeved on the winding roll 13, the squeezing roll 61 will be gradually pushed out, and then the fifth drive motor 252 is started to drive the fifth screw to rotate so that the second clamping mechanism 6 is close to the squeezing roll 61, and then the squeezing roll 61 is clamped by the second clamping mechanism 6, and then the output shaft of the fifth drive motor 252 rotates in the opposite direction to drive the second clamping mechanism 6 to move away from the winding roll 13, thereby resetting the squeezing roll 61.

[0067] After the paper tube is inserted into the winding roller 13, the steel strip is wound on the winding roller 13, and then the winding machine is started to drive the winding roller 13 to rotate, so as to roll the steel strip. When the number of turns of the steel strip on the paper tube reaches the specified value, the steel strip is cut by the cutting machine, and then the paper tube with the steel strip wound is removed by the traveling crane. Then the third sliding assembly 23 is started to reset the storage plate 332, and then the next paper tube is output by the discharging mechanism, and the above process is repeated in sequence. The whole process does not require manual handling of the paper tube, which effectively reduces the labor intensity of the workers and improves the production efficiency.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
