Description

Technical Field

[0001] This invention relates to the technical field of automatic paper tube shredders, and particularly to the technical field of automatic paper tube shredders. Background Technology

[0002] With the continuous development of my country's economic construction, the level of automation is constantly improving. As an important auxiliary material in the production of chemical fibers, paper tubes are subject to increasingly higher requirements. Currently, the small filaments switched over in the chemical fiber industry are recycled into paper tubes by manually stripping them. This manual stripping method is labor-intensive, easily damages the surface of the paper tubes, resulting in a decline in paper tube quality and low work efficiency.

[0003] To address the aforementioned issues, some machine-based wire stripping devices exist on the market, such as the cutting device disclosed in application number 201911096314.5. Compared to existing manual wire stripping techniques, the cutting device provided by this invention has the following advantages: the wire cake is placed on a support base, which fixes the wire cake. Then, the heating unit heats the cutting blade to a certain temperature, and the cutting blade moves towards the wire on the wire cake. When the cutting blade contacts the wire, the wire melts due to the heat, thereby breaking the wire and separating it from the roll, thus avoiding damage to the roll when the cutting blade cuts the wire.

[0004] Although the above invention has the function of automatically peeling fibers, it also has the following drawbacks:

[0005] 1. Low material loading and unloading efficiency: The above invention can only automatically peel the wire, and loading and unloading still require manual labor, which results in low efficiency due to purely manual loading and unloading.

[0006] 2. Insufficient positioning accuracy of the roll: Since the above invention relies on manual feeding, it is easy for slight errors to occur in the placement of the roll, which in turn leads to insufficient wire cutting;

[0007] 3. Incomplete cutting by the cutting blade: The cutting blade of the invention can only move vertically. To ensure that the thread is cut completely, the cutting blade and the outer wall of the roll must be completely parallel. However, manual feeding, the easy deformation of the paper roll itself, and the fact that the paper roll is not necessarily a perfect cylinder can easily lead to the cutting blade and the outer wall of the roll not being completely parallel. As a result, the thread near the outer wall of the roll can only partially contact the cutting blade, which leads to incomplete cutting. Summary of the Invention

[0017] The beneficial effects of this invention are as follows: This invention has a simple structure and reasonable design, enabling fully automated operation, improving slicing efficiency and precision, and ensuring that the slicing coil is fully cut. By setting two feeding slide mechanisms, after the slicing cake on the left feeding slide mechanism is fed, the slicing cake on the right feeding slide mechanism can still be fed. Simultaneously, during the feeding process on the right feeding slide mechanism, slicing cakes can be added to the left feeding slide mechanism, thus achieving continuous and stable feeding, avoiding interruptions, and improving feeding efficiency. Furthermore, the measuring grating can measure and calculate the center of the slicing cake, facilitating precise gripping of the slicing cake by the robotic arm. The gripping and moving mechanism, composed of a second lead screw slide, a third lead screw slide, a fourth lead screw slide, and a robotic arm, enables high-precision displacement of the robotic arm in all directions, facilitating precise positioning of the robotic arm with the slicing cake and other components. Simultaneously, using the gripping and moving mechanism to grip and feed the slicing cake also improves feeding efficiency. The invention also incorporates a clamping device and a tube-release device. In this method, the clamping device can tighten the wire cake fitted on the jaws, and the card-release device can not only use the jaws to fix the wire cake, but also use the discharge push plate driven by the first cylinder to push the wire cake away from the jaws, so as to move the wire cake down for discharge. The clamping device and the card-release device work together to realize the automatic alignment, automatic positioning and automatic discharge of the wire cake, which improves the positioning accuracy and discharge efficiency of the wire cake. By setting two card-release devices and two cooperating circular knife cutting mechanisms, when the left card-release device and the left circular knife cutting mechanism perform preliminary cutting on the left wire cake, the robot can take advantage of this gap to feed the right card-release device, and the right circular knife cutting mechanism can perform preliminary cutting on the right wire cake. When the right wire cake is initially cut, the left wire cake can take advantage of this gap to be finally cut by the hot melt cutting device and discharged by the left card-release device. In this way, the interval time between different wire cakes can be shortened to the greatest extent, and continuous and stable wire cake cutting can be achieved, which greatly improves the wire cake cutting efficiency.

[0038] Working process of this invention:

[0039] During operation, the control panel 15 controls the operation of all components of the automatic paper tube shredder of this invention.

[0040] Step 1: Run the feeding slide mechanism 3. First, place several silk cakes (made of silk thread wound on paper tubes) on the upper ends of the two material support rods 37 of each feeding slide mechanism 3. Place the silk cakes between the left limit vertical plate 36 and the movable push plate 33 along the setting direction of the first lead screw slide 32. Then, start the first lead screw slide 32. The first lead screw nut 322 drives the movable push plate 33 to move towards the left limit vertical plate 36. The movable push plate 33 presses the silk cakes onto the left limit vertical plate 36. Then, the measuring grating 38 measures the center of the silk cakes to facilitate the subsequent clamping and moving mechanism 4 to clamp them.

[0041] Step 2: Operate the clamping and moving mechanism 4. First, the two second lead screw slides 41 move synchronously, and the two second lead screw nuts 412 drive the third lead screw slide 42 to move back and forth until it is directly above the material slide mechanism 3. Then, the third lead screw slide 42 moves, and the third lead screw nut 422 drives the fourth lead screw slide 43 to move to directly above the wire cake near the left limit vertical plate 36. Then, the fourth lead screw slide 43 moves, and the fourth lead screw nut 432 drives the robot arm 45 to move downwards. After the robot arm 45 moves downwards and approaches the wire cake, it clamps the wire cake. Then, the fourth lead screw nut 43... 2. Move the robot arm 45 upward to above the left limit vertical plate 36. Then, the third lead screw nut 422 moves the four lead screw slide 43 to the left into the processing channel 13. Then, the fourth lead screw nut 432 moves the robot arm 45 downward to the right side of the tube release device 5. The paper cake should be coaxial with the chuck cylinder 51. Then, the third lead screw nut 422 moves the four lead screw slide 43 further to the left, and the paper cake tube is placed on several jaws 52. Then, the robot arm 45 releases the grip on the paper cake. Then, the robot arm 45 moves away from the jaws 52 and moves to pick up a new paper cake.

[0042] Step 3: Run the card release device 5 and the clamping device 2. First, the push rod 21 extends and the small diameter end of the clamping truncated cone 22 enters the inner hole of the paper tube. The large diameter end of the truncated cone 22 presses the paper tube onto the limiting U-shaped card 521. At the same time, the truncated cone 22 will correct the posture of the paper tube. Then, several claws 52 move outward in sync and press against the inner wall of the paper tube to fix the paper tube on the claws 52.

[0043] Step 4: Activate the circular knife cutting mechanism 6. First, the lifting cylinder 65 drives the second cylinder 64 to descend. Then, the blade of the circular knife motor 642 rotates. Then, the second cylinder 64 drives the circular knife motor 642 to move to the right. During the rightward movement, the blade of the circular knife motor 642 cuts the silk layer on the silk cake, leaving about 1mm of the silk layer uncut. Then, after the blade of the circular knife motor 642 moves to the right side of the silk cake, the circular knife motor 642 first moves upward, and then moves to the left into the installation channel 16.

[0044] Step 5: Operate the hot cutting moving device 9. The fifth lead screw slide 91 drives the hot cutting lifting device 8 and the hot melt cutting device 7 to move above the shredded cake that has been initially cut by the circular knife motor 642. The blade of the knife body 73 should be adapted to the gap cut by the circular knife motor 642 on the shredded cake.

[0045] Step 6: Operate the hot melt cutting device 7, heating tube 731 heats the blade body 73;

[0046] Step 7: Operate the hot cutting lifting device 8, and the hot melt cutting device 7 descends. The blade 73 hot melts and cuts the remaining 1mm of wire layer on the wire cake in step 4. During the cutting process of the blade 73, the right end of the blade 73 contacts the wire layer first. Then, the electric cylinder 76 is started. Under the action of the first hinge support 732 and the second hinge support 733, the blade 73 rotates to the left. During the rotation, the blade of the blade 73 gradually contacts the wire layer from right to left to ensure that the wire layer is fully hot melted and cut by the blade 73. After the wire layer is hot melted and cut, the hot melt cutting device 7 moves up away from the wire cake.

[0047] Step 8: Run the paper tube release device 5. First, the chuck 52 releases its grip on the paper tube. Then, the first cylinder 58 shortens, and the discharge push plate 56 moves to the right to push the paper cake away from the chuck 52. The paper cake falls into the discharge basket 18.

[0048] This invention features a simple structure and reasonable design, enabling fully automated operation, improving shredding efficiency and precision, and ensuring that the shredded wire is completely cut. By setting two feeding slide mechanisms 3, after the shredded wire cake on the left feeding slide mechanism 3 is fed, the shredded wire cake on the right feeding slide mechanism 3 can still be fed. Simultaneously, during the feeding process on the right feeding slide mechanism 3, shredded wire cakes can be added to the left feeding slide mechanism 3, thus achieving continuous and stable feeding, avoiding feeding interruptions, and thereby improving efficiency. This improves feeding efficiency, and the measuring grating 38 can also measure and calculate the center of the silk cake, facilitating precise gripping of the silk cake by the robotic arm 45. The gripping and moving mechanism 4, composed of the second lead screw slide 41, the third lead screw slide 42, the fourth lead screw slide 43, and the robotic arm 45, enables high-precision displacement of the robotic arm 45 in all directions, facilitating precise positioning of the robotic arm 45 with the silk cake and other components. Simultaneously, using the gripping and moving mechanism 4 to grip the silk cake for feeding also improves feeding efficiency. Furthermore, the use of the clamping device 2 and the tube-release device 5 further enhances the feeding efficiency. The tightening device 2 can tighten the wire cake fitted on the jaw 52. The wire cake release device 5 can not only use the jaw 52 to fix the wire cake, but also use the discharge push plate 56 driven by the first cylinder 58 to push the wire cake away from the jaw 52, ​​so as to move the wire cake downward and discharge it. The tightening device 2 and the wire cake release device 5 cooperate with each other to realize the automatic alignment, automatic positioning and automatic discharge of the wire cake, which improves the positioning accuracy and discharge efficiency of the wire cake. By setting two wire cake release devices 5 and two cooperating circular knife cutting mechanisms 6, when the left wire cake release device 5 cooperates with the left circular knife cutting mechanism 6, While the cutting mechanism 6 is performing preliminary shredding on the left side of the shredded cake, the robotic arm 45 can take advantage of this gap to feed the right side of the tube-disconnecting device 5. The right side circular knife cutting mechanism 6 can also perform preliminary shredding on the right side of the shredded cake. While the right side of the shredded cake is being preliminarily shredded, the left side of the shredded cake can take advantage of this gap to be finally shredded by the hot melt cutting device 7 and discharged by the left side of the tube-disconnecting device 5. In this way, the interval time between different shredded cakes can be shortened to the greatest extent, and continuous and stable shredding of shredded cakes can be achieved, which greatly improves the shredding efficiency of the shredded cakes.
