Description

Technical Field

[0001] This invention relates to the field of slitting equipment technology, specifically to a winding and slitting device and method that facilitates material changing. Background Technology

[0002] A paper slitting machine is a specialized industrial device that precisely cuts large-format roll raw materials (such as paper, film, and other related thin substrates) into multiple narrow rolls or flat sheets of the required width according to preset dimensions through high-speed shearing or slicing. It consists of unwinding, traction, slitting, winding, and control systems, and features high precision, high efficiency, and stable tension control.

[0003] Existing paper slitting machines, during the slitting and winding process, need to cut paper into different specifications according to different production requirements. When the diameter of the wound paper reaches a set value, the machine needs to be stopped for unloading. For this reason, existing paper slitting machines usually adopt a semi-automatic mechanical assistance method to adjust the spacing between the circular knives and perform unloading operations for the wound paper. However, in this process, due to the lack of real-time position feedback and precise drive coordination, the position of the circular knives still needs to be repeatedly adjusted when adjusting the spacing between the circular knives. When unloading the paper, not only is it necessary to manually disengage and engage the coupling, but it is also necessary to manually move the wound paper with the help of a handling device (such as a handcart). In order to further improve the production efficiency of paper slitting and winding, this paper provides a winding and slitting equipment and method that is easy to change materials, which can eliminate the drawbacks of the existing equipment.

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0050] In one embodiment, such as Figures 1-8As shown, the easy-to-change winding and slitting equipment includes a first support frame 1. A second support frame 13 is fixedly connected to one side of the bottom of the first support frame 1.

A first air shaft 12 is arranged above each of the two movable base plates 11. A second air shaft 15 is rotatably connected inside the second support frame 13. Multiple circular knife assemblies 16 are arranged laterally at equal intervals inside the second support frame 13. A fixed base 14 is arranged on the side of each of the two movable base plates 11 away from the second support frame 13. A second winding traction roller 7 is rotatably connected inside the second support frame 13. Two fixed cylinders 10 are symmetrically installed at the bottom of the inner wall of the 3. Two first winding traction rollers 6 are located between the second winding traction roller 7 and the fixed cylinders 10. Two movable base plates 11 are fixedly connected to the output ends of the two fixed cylinders 10 respectively. The second air shaft 15 is located between the second winding traction roller 7 and the first winding traction roller 6. Multiple limiting rollers for limiting the paper are rotatably connected on the first support frame 1. A third servo motor and a fourth servo motor are installed at one end of the second support frame 13. The second winding traction roller 7 is driven by the third servo motor, and the second air shaft 15 is driven by the fourth servo motor. A tension sensor 5 is installed inside the side of the first support frame 1 away from the second support frame 13. An unwinding assembly 8 is provided on the side of the first support frame 1 away from the second support frame 13. A feeding mechanism for convenient paper feeding is provided on the movable base plate 11.

[0051] The feeding mechanism includes:

[0052] A support rotating rod 205 is set above the movable base plate 11. The support rotating rod 205 is located below the first air expansion shaft 12. The outer wall of the support rotating rod 205 is symmetrically fixedly connected to a right wall plate 201 and a left wall plate 209. The first air expansion shaft 12 is located between the right wall plate 201 and the left wall plate 209. A support seat 202 is set at one end of the right wall plate 201 located at the left wall plate 209. The support seat 202 is fixedly connected to the movable base plate 11. A sliding groove for the end shaft to move is opened at the position where the support seat 202 connects with the end shaft of the first air expansion shaft 12.

[0053] The fixed base 14 is equipped with a conveying mechanism for automatically conveying the paper being fed;

[0054] The second support frame 13 is provided with an adjustment mechanism for adjusting the spacing of the multiple circular knife assemblies 16;

[0055] In this embodiment, during use, the spacing between multiple circular blade assemblies 16 can be conveniently adjusted according to different production needs through the adjustment mechanism. After the spacing between multiple circular blade assemblies 16 is adjusted, the second air shaft 15 is started to expand, so that the second air shaft 15 can be fixedly connected to multiple second circular blades. When cutting paper, the fourth servo motor is started to drive the second air shaft 15 to rotate. At this time, multiple second circular blades rotate under the drive of the second air shaft 15, so that the paper can be cut into different specifications according to the needs.

[0056] Then, the paper roll can be conveyed to one side of the unwinding assembly 8 by the conveying mechanism. At this time, the paper roll can be manually installed on the unwinding assembly 8, and the end of the paper roll is pulled and fixed on the outer wall of the first air shaft 12. Then, the fixed cylinder 10 is activated to drive the moving base plate 11 to move towards the second support frame 13 through the slide table and guide rail until the first air shaft 12 contacts the outer wall of the first winding traction roller 6.

[0057] Then, the third servo motor is started to drive the second winding traction roller 7 to perform a traction operation on the paper. At the same time, the first air shaft 12 is driven to rotate through the feeding mechanism. At this time, according to the diameter of the paper winding, the fixed cylinder 10 is started to push the moving base plate 11 to move, so as to ensure that the outer wall of the paper winding is always in contact with the outer wall of the first winding traction roller 6, thereby ensuring the stability of the paper winding tension. In this way, the paper after slitting can be wound up.

[0058] When the paper is wound to the finished diameter, the movement lock on the end shaft of the first air shaft 12 is released by the unloading mechanism, and the slit roll paper is moved above the fixed base 14 by the first air shaft 12. At the same time, the slit roll paper can be limited and supported by the conveying mechanism. Then the other end of the first air shaft 12 is released by the unloading mechanism.

[0059] Then, the first air shaft 12 is activated to retract, thereby separating the first air shaft 12 from the roll paper. The roll paper can then be automatically conveyed by the conveying mechanism, thus achieving the purpose of automatic unloading of the roll paper. When the unloading of the roll paper is completed, the above operation is reversed, which can drive the first air shaft 12 to automatically reset and be installed and fixed. Then, the above operation is repeated to continue the cutting, winding and automatic unloading of the slit roll paper.

When the circular blade assembly 16 moves to the designated position, the extrusion assembly 407 is activated to release the extrusion on the outer wall of the second conveyor belt 403. Then, the above operation is repeated. The spacing between multiple circular blade assemblies 16 can be easily adjusted according to different production needs.

[0086] After the spacing between the multiple circular blade assemblies 16 is adjusted, the second air shaft 15 is started to expand, thereby squeezing the inner walls of the multiple second circular blades. This allows the second air shaft 15 to be fixedly connected to the multiple second circular blades. When cutting the paper, the fourth servo motor is started to drive the second air shaft 15 to rotate. At this time, the multiple second circular blades rotate under the drive of the second air shaft 15, so that the paper can be cut into different specifications according to the requirements.

[0087] Then, the first servo motor is started to drive the first transmission roller to rotate. At this time, the first conveyor belt 302 drives the other first transmission roller to rotate under the drive of the first transmission roller. At the same time, the movable base 301 moves at the top of the fixed base 14 through the knurled bolts 303 and the rollers 305 under the drive of the first conveyor belt 302. At this time, the movable base 301 moves along the inner wall of the straight slide groove through the knurled bolts 303 and the rollers 305 to limit the movement. In this way, the roll paper can be conveyed to one side of the unwinding assembly 8. Then, the roll paper can be manually installed on the unwinding assembly 8, and the end of the roll paper is pulled and fixed on the outer wall of the first air shaft 12. Then, the fixed cylinder 10 is started to drive the movable base plate 11 to move towards the second support frame 13 through the slide table and guide rail until the first air shaft 12 contacts the outer wall of the first winding traction roller 6.

[0088] Then, the third servo motor is started to drive the second winding traction roller 7 to traction the paper. During this process, the paper can be limited and conveyed by the limiting roller, and the tension of the paper can be detected in real time by the tension sensor 5. The two first winding traction rollers 6 can guide the slit paper. At this time, the winding motor 204 is started to drive the second synchronous wheel to rotate. At the same time, the first synchronous wheel drives the third synchronous wheel to rotate through the first transmission belt driven by the second synchronous wheel. At this time, the fourth synchronous wheel drives the transmission slide rod 2013 to rotate through the limiting slider through the second transmission belt driven by the third synchronous wheel. At the same time, the transmission slide rod 2013 drives the first air shaft 12 to rotate synchronously through the coupling 2012. At this time, the docking block rotates synchronously under the drive of the first air shaft 12, so as to perform the winding operation of the slit paper.

[0089] During this process, according to the diameter of the paper winding, the fixed cylinder 10 is activated to push the moving base plate 11 to slowly reset, thereby ensuring that the outer wall of the paper winding is always in contact with the outer wall of the first winding traction roller 6. At the same time, by controlling the speed of the winding motor 204, the stability of the paper winding tension can be ensured by the speed difference between the first air shaft 12 and the first winding traction roller 6.

[0090] When the paper is wound to the finished diameter, the winding motor 204 is stopped and the support cylinder 2015 is started. The transmission slide rod 2013 drives the active end to separate the elastic element from the driven end. At the same time, the transmission slide rod 2013 slides along the inner wall of the fourth synchronous wheel, thereby releasing the movement lock of the first air shaft 12 end shaft.

[0091] Then, the two drive motors 206 are started, driving the two spur gears 2010 to rotate. At this time, the two spur gear rings 2011 rotate along the outer wall of the connecting ring and supporting rotating rod 205 under the meshing drive of the two spur gears 2010. Simultaneously, the left arm 208 and the right arm 203 rotate along the outer wall of the supporting rotating rod 205 under the drive of the two spur gear rings 2011. At this time, the positioning cylinder 207 separates from the left wall plate 209 under the drive of the left arm 208. Meanwhile, driven by the docking block and the right arm 203, the first air shaft 12 moves the cut roll paper to the top of the fixed base 14 and makes the roll paper contact the upper surface of the support platform 304. In this way, the support platform 304 can limit and support the cut roll paper. Then, the two drive motors 206 are stopped and the positioning cylinder 207 is started to drive the docking block to separate from the first air shaft 12, thereby releasing the fixed connection between the first air shaft 12 and the positioning cylinder 207.

[0092] Then, a drive motor 206 is started to drive a spur gear 2010 to rotate. At this time, a spur gear ring 2011, driven by the meshing of the spur gear 2010, drives the left arm 208 to rotate and reset along the outer wall of the support rod 205. At the same time, the positioning cylinder 207 is moved synchronously under the drive of the left arm 208 until the positioning cylinder 207 contacts the inner wall of the positioning groove. Then, the first air shaft 12 is started to retract, so that the first air shaft 12 can be separated from the paper roll. Then, the support platform 304 can automatically convey the paper roll by moving the base 301, the first conveyor belt 302, and the roller 305, thereby realizing the purpose of automatic paper roll feeding.

[0093] When the paper roll is unloaded, another drive motor 206 is started to drive another spur gear 2010 to rotate. At the same time, another spur gear ring 2011, driven by the other spur gear 2010, drives the right arm 203 to flip and reset. At this time, the first air shaft 12 moves and resets under the drive of the right arm 203, and drives the driven end to move into the support seat 202. Then, the positioning cylinder 207 and the support cylinder 2015 are started to reverse the above operation, which can automatically engage the end shaft of the first air shaft 12. Then, the above operation is repeated to continue the cutting, winding and automatic unloading of the slit paper roll.

[0094] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
