Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper cutters, in particular to an automatic corrugated paper cutter replacement device. Background Technique

[0002] Corrugated paper needs to be cut before leaving the factory. In order to ensure the flatness of the cut, a cutter is required. To avoid wear of the cutter due to long-term use, the cutter needs to be replaced.

[0003] Currently, when replacing the cutter, it is necessary to manually disassemble the cutter. After removing the old blade, a new cutter is taken for replacement. However, the new cutter is relatively sharp and can easily hurt the operator during the installation process, resulting in inconvenience in replacement.

[0004] To solve the above defects, the cutter component of a fully automatic paper straw machine with a cutter lifting mechanism, with the publication number of CN209755391U, can lift the cutter group by a certain distance during shutdown maintenance by setting a cutter lifting mechanism, increasing the slitting gap, and greatly improving the personal safety of the staff during maintenance.

[0005] To solve the above defects, there is a quick replacement tooling for a tipping paper cutter with the publication number of CN221249098U. It temporarily installs arc-shaped plates with limit flanges and round covers on the inner and outer end faces of the cutter roller shaft respectively. Due to the inconvenient installation of the arc-shaped plate on the inner end face, only the arc-shaped section that can be used is retained in the design, which is equivalent to cutting off the rest of the round cover. During use, the arc-shaped plate is pressed by adjusting the pressure rod on the pressing block. When replacing a single cutter, first pre-install the cutter in the cutter groove of the cutter roller shaft. After installing the arc-shaped plate and the round cover respectively, pull the pre-installed cutter outwards so that it is in full contact with the limit flanges of the round cover and the arc-shaped plate. Finally, tighten the bolts for fixing the cutter.

[0006] In the actual use of the above device, although the danger of replacing the cutter can be reduced, manual replacement of the cutter is still required. When the operator comes into contact with the cutter installation, there is still a possibility of the cutter hurting people, resulting in the inability to guarantee safety.

[0007] Therefore, we have proposed an automatic corrugated paper cutter replacement device that can well solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Embodiment 1:

[0034] The present utility model solves the problem that in the prior art, it is necessary to manually replace the cutter, and when the operator contacts the cutter installation, there is also a possibility of the cutter hurting people, resulting in the inability to guarantee safety. Through the movement of the clamping block 15, the purpose of automatic installation can be achieved, thereby improving safety, and discloses:

[0035] Base 1, on which a slide rail 2 is provided, and a bracket 3 is nested and slidably arranged inside the slide rail 2; further comprising: a hydraulic rod 4 is fixed to the top of the bracket 3 by screws, and a tool rest 5 is fixed to the bottom of the hydraulic rod 4 by screws, and a cutter body 6 is accommodated at the bottom of the tool rest 5. A moving plate 7 is slidably arranged inside the tool rest 5, and the inner end of the moving plate 7 penetrates and slides on a fixed rod 8, and both ends of the fixed rod 8 are fixed inside the tool rest 5. The inner end of the fixed rod 8 is connected to a first pulling rope 10, and the bottom of the first pulling rope 10 is wound and connected to a winding roller 12, and the middle of the winding roller 12 is key-connected to the front end of a rotating rod 13. Both ends of the rotating rod 13 are connected to the inside of the tool rest 5 through bearings, and a gear 14 is key-connected to the rear end of the rotating rod 13, and a clamping block 15 is engaged with the bottom of the gear 14. The clamping block 15 slides inside the tool rest 5, and the inner end of the tool rest 5 extends into the inside of a clamping groove 16 to form a clamping mechanism, and the clamping groove 16 is opened at the tops of the cutter body 6 and a secondary cutter 20. The outer end of the clamping block 15 is connected to a second spring 17, and the outer end of the second spring 17 is connected to the inside of the tool rest 5; a receiving box 18 is nested at the left end of the base 1, and a tool groove 19 is opened at the front end of the receiving box 18, and a secondary cutter 20 is slidably placed at the rear end of the receiving box 18. A first spring 9 is nested at the top of the fixed rod 8, and the bottom of the first spring 9 is connected to the top of the moving plate 7. A roller 11 is attached to the bent portion of the first pulling rope 10, and the roller 11 is connected to the inside of the tool rest 5 through a bearing. The bottom of the inner end of the clamping block 15 is arc-shaped, and the arc surface of the inner end of the clamping block 15 is fitted with the outermost end of the clamping groove 16. An opening is provided at the left end of the base 1, and the diameter of the opening at the left end of the base 1 is smaller than the sum of the diameters of the tool rest 5 and the moving plate 7, and the diameter of the opening at the left end of the base 1 is smaller than the diameter of the tool rest 5;

[0036] Reference Figures 1 to 6, the telescopic movement of the hydraulic rod 4 can drive the tool rest 5 to move, and then make the tool rest 5 move to cut the corrugated paper through the cutter body 6. When replacing the cutter body 6, by moving the support 3, the support 3 can slide on the base 1 through the slide rail 2. After moving to the position, the movement of the hydraulic rod 4 drives the cutter body 6 to move, so that the cutter body 6 can extend into the inside of the tool groove 19, and the movement of the tool rest 5 will extend into the inside of the base 1. Then, the movement of the tool rest 5 drives the moving plate 7 to move, so that the moving plate 7 will be squeezed between the moving plate 7 and the base 1. Then, the movement of the moving plate 7 will slide on the fixed rod 8, so that the movement of the moving plate 7 will squeeze the first spring 9, and then the first spring 9 is compressed and stressed. And the movement of the moving plate 7 makes the first pull rope 10 become slack. Therefore, the second spring 17 pulls the block 15 to move, so that the block 15 will move into the inside of the tool rest 5, and then the block 15 will disengage from the engagement with the card slot 16, and the movement of the block 15 will drive the gear 14 to rotate, so that the rotation of the gear 14 drives the winding roller 12 to wind the first pull rope 10 through the rotating rod 13. Then, the cutter body 6 will fall into the inside of the tool groove 19 due to gravity. Then, the hydraulic rod 4 is retracted, and the moving plate 7 will disengage from the extrusion of the base 1. Then, the first spring 9 pushes the moving plate 7 to reset, and the reset of the moving plate 7 drives the first pull rope 10 to move through the roller 11. The movement of the first pull rope 10 drives the gear 14 to rotate through the winding roller 12, so that the gear 14 drives the block 15 to reset, and the movement of the block 15 will stretch the second spring 17, so that the second spring 17 is stressed. The hydraulic rod 4 drives the tool rest 5 to rise, and then the support 3 is moved to the right, and then the hydraulic rod 4 drives the tool rest 5 to move downward, so that the block 15 will squeeze the secondary cutter 20, so that the block 15 will move automatically under the extrusion, and the secondary cutter 20 will extend into the inside of the tool rest 5. After the secondary cutter 20 moves to the position, the block 15 will extend into the inside of the secondary cutter 20 to form an engagement, so as to fix the secondary cutter 20, and then achieve the purpose of automatic replacement, thereby improving the safety of replacement;

[0037] Embodiment 2:

[0038] The present utility model solves the problem that there will be debris generated after cutting the corrugated paper, which is inconvenient for subsequent processing. The cleaning function can be achieved through the nozzle 23, and it is disclosed that:

[0039] The inner wall of the support 3 is rotatably connected with a nozzle 23 through a bearing, and the outer end of the nozzle 23 is connected to an external hair dryer through an air pipe 24, and the air pipe 24 penetrates through the inside of the support 3;

[0040] Reference Figure 1 and Figure 2, after the cutting tool body 6 cuts the corrugated paper, debris will be generated. Through an external hair dryer, gas can be transported through the air pipe 24 to the nozzle 23, and then the air can be blown onto the cut corrugated paper through the nozzle 23. Then, the debris on the corrugated paper can be cleaned by the air, thus avoiding the influence of debris adsorption on subsequent processing;

[0041] Embodiment 3:

[0042] The utility model solves the problem that the cleaning range of the nozzle 23 in Embodiment 2 is relatively limited. The nozzle 23 can be driven to swing by the second pull rope 21, thereby improving the cleaning range, and discloses:

[0043] The top of the nozzle 23 is connected with a second pull rope 21, and the top of the second pull rope 21 is connected to the top of the tool rest 5 through a limit wheel 22, and the outer end of the limit wheel 22 is fixed on the inner wall of the bracket 3;

[0044] Reference Figure 1 and Figure 2 , the movement of the hydraulic rod 4 drives the tool rest 5 to move, and the movement of the tool rest 5 drives the second pull rope 21 to move, so that the second pull rope 21 moves to drive the nozzle 23 to rotate through the limit wheel 22. And through the reverse movement of the tool rest 5, the second pull rope 21 becomes slack, so that the nozzle 23 rotates in the reverse direction due to its own weight. In this way, the nozzle 23 can rotate reciprocally, thereby improving the cleaning range.

[0045] Working principle: When using the automatic corrugated paper cutting tool replacement device, first, reference Figures 1 to 6, the telescopic movement of the hydraulic rod 4 can drive the tool rest 5 to move, and then the tool rest 5 moves to cut the corrugated paper through the cutter body 6. When replacing the cutter body 6, by moving the support 3, the support 3 can slide on the base 1 through the slide rail 2. After moving to the position, the movement of the hydraulic rod 4 drives the cutter body 6 to move, and the movement of the tool rest 5 will extend into the interior of the base 1. Then, the movement of the tool rest 5 drives the moving plate 7 to move, and the movement of the moving plate 7 makes the first pulling rope 10 become slack. Therefore, the force of the second spring 17 pulls the clamping block 15 to move, so that the clamping block 15 will move into the interior of the tool rest 5. Then, the hydraulic rod 4 is retracted, and the moving plate 7 will disengage from the extrusion of the base 1. Then, the first spring 9 pushes the moving plate 7 to reset, and the reset of the moving plate 7 drives the first pulling rope 10 to move through the roller 11. The movement of the first pulling rope 10 drives the gear 14 to rotate through the winding roller 12. Then, the support 3 is moved to the right, and then the tool rest 5 is driven by the hydraulic rod 4 to move downward, so that the clamping block 15 will squeeze the secondary cutter 20, and the clamping block 15 will extend into the interior of the secondary cutter 20 to form a clamping, so as to fix the secondary cutter 20, and then achieve the purpose of automatic replacement, thereby improving the safety of replacement;

[0046] Reference Figure 1 and Figure 2 , after the cutter body 6 cuts the corrugated paper, debris will be generated. Through an external hair dryer, and then through the nozzle 23, air can be blown onto the cut corrugated paper, and then the air can clean the debris on the corrugated paper, so as to avoid the influence of debris adsorption on subsequent processing;

[0047] Reference Figure 1 and Figure 2 , the movement of the hydraulic rod 4 drives the tool rest 5 to move, and the movement of the tool rest 5 drives the second pulling rope 21 to move. And due to the reverse movement of the tool rest 5, the nozzle 23 rotates in the reverse direction by the weight of the nozzle 23. In this way, the nozzle 23 can rotate reciprocally, thereby increasing the cleaning range.
