Description

Technical Field

[0001] This invention relates to the technical field of rust-proof paper processing equipment, and in particular to an automatic rust-proof paper cutting device. Background Technology

[0002] Vapor phase corrosion inhibitor paper is made from high-quality rust-inhibiting base paper and a specially formulated, highly efficient vapor phase corrosion inhibitor through a special process. In the metal packaging process, rust-inhibiting paper is needed for protective packaging to prevent the metal from rusting. This requires cutting equipment to cut the rust-inhibiting paper for easy packaging of the metal.

[0003] Patent CN216731921U discloses a cutting device for metal rust-proof paper, including a base plate. Grooves are formed on both sides of the top of the base plate. Vertical plates are fixed to both ends of the top of the base plate. A first sliding groove is formed on the inner end face of the vertical plate, and a first slider is slidably connected within the first sliding groove. A cutter is fixed between the two first sliders. Fixed rods are fixed on both sides of the top of the cutter. First support rods are hinged to both sides of the cutter. A second sliding groove is formed on the outer side of the first support rod, and a second slider is slidably connected within the second sliding groove. A second spring is fixed between the inner walls of the second slider and the second sliding groove. A second support rod is hinged between the second slider and the first support rod. A mounting frame is fixed to the bottom of the first support rod, and rollers are rotatably connected between the inner walls of both ends of the mounting frame. By rolling the rollers on the surface of the rust-proof paper, the two rollers can tighten and flatten the rust-proof paper. Finally, the cutter cuts the rust-proof paper, effectively preventing skewed cutting.

[0004] Before cutting, the rust-proof paper is stretched and flattened.

[0016] In one embodiment of the present invention, a guide rod is fixedly connected to the inner bottom wall of the through groove, the top end of the guide rod passes through the second rack and is fixedly connected to the inner top wall of the through groove, and the outer wall of the clamping plate is provided with anti-slip texture.

[0017] The technical solution of the present invention has the following advantages compared with the prior art:

[0018] 1. To prevent the cut rust-proof paper from scattering due to springback, the present invention can move the rust-proof paper away from the take-up roller by a drive assembly before cutting. At the same time, the first toothed strip partially pops out of the groove under the pressure of the first spring, and the limiting block rotates synchronously. With the help of the auxiliary plate, the rust-proof paper is pressed and positioned, and the rust-proof paper can be cut. At this time, the cut end of the rust-proof paper is pressed by the two limiting blocks, which counteracts the springback force of the rust-proof paper to prevent it from scattering due to springback. Afterwards, the drive assembly drives the clamping frame to move and reset towards the take-up roller, pushes the first toothed strip back into the groove, and the limiting block rotates, helping to push the rust-proof paper into the clamping frame.

[0019] 2. To prevent the take-up roller from rotating during cutting, this invention limits its rotation and further reduces the impact of rust-proof paper rebound on cutting. During installation, one end of the transmission rod can be inserted into positioning holes on both sides of the take-up roller. This ensures the rotation of the take-up roller can be limited via the transmission rod. When the drive assembly moves the rust-proof paper away from the take-up roller, the second rack drives the third gear through multiple equally spaced second gears and a synchronous belt. The drive rod, through a worm gear and worm, drives the transmission rod, which in turn drives the take-up roller to rotate, assisting in the laying of the rust-proof paper. When the clamping frame stops moving, i.e., when cutting is to be performed, the take-up roller is limited by the meshing of the gears and rack. This, combined with the positioning mechanism, counteracts and mitigates the impact of rust-proof paper rebound, preventing the take-up roller from rotating during cutting and causing the cut length to exceed the required standard.

[0020] 3. In this invention, a fixing block is fixedly connected to the top of the base. After the cutting is completed, as the second cylinder drives the clamping plate to move upward, the clamping plate applies pressure to the conical block and retracts it into the limiting groove until the clamping plate rises to the top. At this time, under the pressure of the third spring, the protective block drives the conical block to reset. The conical block moves to the bottom of the clamping plate to prevent the second cylinder from being damaged and suddenly causing the clamping plate to fall. This avoids unnecessary physical injury to the workers caused by the second cylinder suddenly causing the clamping plate to fall when the cut rust-proof paper is removed. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0033] Please see Figures 1-9 As shown, an automatic rust-proof paper cutting device includes a cutting seat 1; a shielding frame 2 is fixedly connected to the top of the cutting seat 1, a first cylinder 3 is fixedly connected to the top of the shielding frame 2, the output end of the first cylinder 3 passes through the shielding frame 2 and is fixedly connected to a cutting blade 4, a clamping frame 5 is provided on the top of the cutting seat 1, a second cylinder 6 is fixedly connected to the top of the clamping frame 5, the output end of the second cylinder 6 passes through the top end of the clamping frame 5 and is fixedly connected to a clamping plate 7, a take-up roller 8 is provided on one side of the cutting seat 1, a driving component is provided on the cutting seat 1 and is used to drive the clamping frame 5 to move, and a transmission component is provided on the cutting seat 1 and is used to rotate and position the take-up roller 8.

[0034] The cutting seat 1 is provided with a positioning mechanism 9. The positioning mechanism 9 includes an auxiliary plate 91 fixedly connected to the top of the cutting seat 1. A groove 92 is opened on one side of the auxiliary plate 91 near the clamping frame 5. A first rack 93 is slidably connected in the groove 92. One end of the first rack 93 is elastically connected to the inner wall of the groove 92 through a first spring 94. The other end of the first rack 93 extends out of the groove 92 and communicates with the outside. An auxiliary rod is rotatably connected to the inner bottom wall of the groove 92. The top end of the auxiliary rod passes through the auxiliary plate 91 and is fixedly connected to a limit block 95. A first gear 96 is fixedly connected to the outer wall of the auxiliary rod located in the groove 92. The first gear 96 meshes with the first rack 93.

[0035] To prevent the cut rust-proof paper from scattering due to springback, before cutting, i.e., when laying the rust-proof paper at startup, the rust-proof paper can be laid on the auxiliary plate 91, with one end extending into the clamping frame 5. Then, the second cylinder 6 is activated to move the clamping plate 7 to clamp and position the end of the rust-proof paper. At this time, the first rack 93 retracts into the groove 92 under the pressure of the clamping frame 5, while simultaneously applying pressure to the first spring 94. Then, through the drive assembly and the clamping frame 5, the end of the rust-proof paper is moved away from the take-up roller 8. At the same time, the first rack 93 partially pops out of the groove 92 under the pressure of the first spring 94. Subsequently, the first gear 96 drives the auxiliary rod to rotate, and the limit block 95 rotates synchronously, working with the auxiliary plate 91 to press and position the rust-proof paper. When the rust-proof paper has been pulled a certain distance by the clamping frame 5 and the clamping plate 7, the first cylinder 3 can be activated. The cutting blade 4 moves to cut the rust-proof paper. At this time, the cut end of the rust-proof paper is pressed by the two limit blocks 95, and the static friction generated can hinder the rebound of the rust-proof paper to avoid the rust-proof paper from becoming scattered due to the rebound. Then, the drive component drives the clamping frame 5 to move and reset towards the take-up roller 8, and pushes the first rack 93 back into the groove 92. The limit block 95 rotates and assists in pushing the rust-proof paper into the clamping frame 5 to achieve the purpose of automatic feeding to the clamping frame 5. Only the rust-proof paper needs to be laid manually when initially installing the take-up roller 8. Subsequently, it can be automatically pulled and laid by the cooperation of the auxiliary plate 91 and the clamping frame 5. At the same time, in order to further reduce the impact of the rust-proof paper rebound, the rotation of the take-up roller 8 can be associated with the movement of the clamping frame 5 through the transmission component. This can also prevent the take-up roller 8 from rotating during cutting and limit the rotation of the take-up roller 8.

[0036] Furthermore, such as Figure 2 and Figure 3As shown, a second rack 10 is fixedly connected to one end of the clamping plate 7, and a through groove adapted to the second rack 10 is opened on one side of the clamping frame 6. The transmission assembly includes a second gear 11 rotatably connected to the top of the cutting seat 1 via a rotating shaft. The second rack 10 is meshed with the second gear 11. A support block 12 is fixedly connected to the side of the cutting seat 1 near the take-up roller 8. A drive rod 13 is rotatably connected to the top of the support block 12. A worm gear 14 is fixedly connected to the outer wall of the drive rod 13. A third gear 16 is fixedly connected to the top of the drive rod 13. The second gear 11 is meshed with the third gear 16 via a synchronous belt 17. A positioning block is fixedly connected to the top of the support block 12. A transmission rod 18 is rotatably connected to the side of the positioning block near the third gear 16. A worm gear 15 is fixedly connected to the outer wall of the transmission rod 18. The worm gear 15 is meshed with the worm gear 14. One end of the transmission rod 18 is inserted into the positioning holes opened on both sides of the take-up roller 8.

[0037] To prevent the take-up roller 8 from rotating during cutting and to limit its rotation, while further reducing the rebound of the rust-proof paper, one end of the transmission rod 18 can be inserted into the positioning holes on both sides of the take-up roller 8 during installation. This ensures that the rotation of the take-up roller 8 can be limited by the transmission rod 18. Then, when the drive assembly moves the rust-proof paper away from the take-up roller 8, the second rack 10 drives the third gear 16 to rotate through multiple equally spaced second gears 11 in conjunction with the synchronous belt 17. The drive rod 13, through the worm gear 14... The worm gear 15 drives the transmission rod 18 to rotate, which in turn drives the take-up roller 8 to rotate, which can assist in the laying of the anti-rust paper. When the clamping frame 5 stops moving and cutting is to be carried out, the transmission between the second rack 10 and the second gear 11 stops. Then, the third gear 16 limits the rotation of the transmission rod 18 through the worm wheel 14 and the worm gear 15. The take-up roller 8 is then limited in rotation. In conjunction with the positioning mechanism 9, the rebound effect of the anti-rust paper is offset and the resulting impact is dealt with. At the same time, the rotation of the take-up roller 8 during cutting is prevented from causing the cutting length to exceed the required standard.

[0038] Furthermore, such as Figure 7 As shown, a positioning rod 19 is fixedly connected to the inner side wall of the groove 92. One end of the positioning rod 19 is inserted into a locking hole opened on the first rack 93. The outer wall of the limiting block 95 is provided with anti-slip texture.

[0039] To prevent the first rack 93 from shifting during movement and affecting its meshing transmission with the first gear 96, a positioning rod 19 is fixedly connected to the inner wall of the groove 92, and one end of the positioning rod 19 is inserted into the locking hole opened on the first rack 93 to position and guide the movement of the first rack 93. Anti-slip texture is provided on the outer wall of the limiting block 95 to increase the friction between the limiting block 95 and the anti-rust paper.

[0040] Furthermore, such as Figure 1 As shown, a positioning groove 20 is provided on one side of the cutting seat 1 near the take-up roller 8. A first lead screw 21 is rotatably connected to the inner wall of the positioning groove 20. One end of the first lead screw 21 passes through the cutting seat 1 and is fixedly connected to a knob. A transmission block 22 is threadedly connected to the outer wall of the first lead screw 21 located in the positioning groove 20. One end of the transmission block 22 extends out of the positioning groove 20. A plug-in rod is rotatably connected to one side of the transmission block 22 near the take-up roller 8. One end of the plug-in rod is inserted into the positioning hole.

[0041] To speed up the cutting process and facilitate the replacement of the take-up roller 8, the take-up roller 8 is positioned and replaced by a drive assembly in conjunction with the transmission rod 18. When the take-up roller 8 needs to be replaced, the knob is turned to drive the first lead screw 21 to rotate, and the transmission block 22 drives the insertion rod to move, so that the end of the insertion rod inserted into the positioning hole is pulled out, and a new take-up roller 8 with rust-proof paper wound on it can be replaced. The insertion rod is then inserted into the positioning hole, and the transmission rod 18 drives it to rotate to lay the rust-proof paper.

[0042] Furthermore, such as Figure 2 and Figure 4 As shown, the top of the cutting seat 1 is provided with a support groove 23, and a support plate 24 is slidably connected in the support groove 23. The bottom end of the support plate 24 is elastically connected to the inner bottom wall of the support groove 23 through a second spring 25. The top end of the support plate 24 extends out of the support groove 23, and the end of the support plate 24 away from the auxiliary plate 91 is set as a cone.

[0043] To prevent excessive stretching of the rust-proof paper during cutting due to the middle being suspended, which would affect its subsequent use, a support groove 23 is provided on the top of the cutting seat 1. A support plate 24 is slidably connected in the support groove 23. With the help of a second spring 25, after the clamping frame 5 moves to the designated position, the support plate 24 pops out under the pressure of the second spring 25 and supports the middle of the rust-proof paper, reducing the possibility of deformation due to cutting.

[0044] Furthermore, such as Figure 2 As shown, the driving assembly includes a driving groove 26 formed on the top of the cutting seat 1. A second lead screw 27 is rotatably connected to the inner side wall of the driving groove 26. A threaded block is threadedly connected to the outer wall of the second lead screw 27. The top end of the threaded block extends out of the driving groove 26 and is fixedly connected to the bottom of the clamping frame 5.

[0045] In order to drive the clamping frame 5 to reciprocate and continuously perform automatic cutting, the motor set in the base or the external motor is started to drive the first lead screw 21 to rotate, which in turn drives the clamping frame 5 to reciprocate via the threaded block.

[0046] Furthermore, such as Figure 8 and Figure 9 As shown, a fixing block 28 is fixedly connected to the top of the cutting seat 1. A limiting groove is formed in the fixing block 28. A protective block 29 is slidably connected in the limiting groove. One end of the protective block 29 is elastically connected to the inner wall of the limiting groove through a third spring 31. A conical block 30 is fixedly connected to the other end of the protective block 29. The other end of the conical block 30 passes through the fixing block 28 and communicates with the outside.

[0047] To prevent unnecessary physical injury to workers caused by the sudden drop of the clamping plate 7 due to damage to the second cylinder 6 when removing the cut rust-proof paper, a fixing block 28 is fixedly connected to the top of the base. After cutting, as the second cylinder 6 moves the clamping plate 7 upward, the clamping plate 7 applies pressure to the conical block 30 and retracts it into the limiting groove until the clamping plate 7 rises to the top. At this time, under the pressure of the third spring 31, the protective block 29 moves the conical block 30 back to its original position, and the conical block 30 moves to the bottom of the clamping plate 7 to prevent the clamping plate 7 from suddenly dropping due to damage to the second cylinder 6.

[0048] Furthermore, such as Figure 1 and Figure 2 As shown, a placement plate 32 is fixedly connected to the side of the cutting seat 1 away from the winding roller 8. A placement groove is provided on the top of the placement plate 32, and a collection plate 33 is provided on the top of the placement plate 32. A collection groove is provided on the top of the collection plate 33.

[0049] To facilitate the taking, loading, and transfer of the cut rust-proof paper, a placement plate 32 is fixedly connected to the side of the cutting seat 1 away from the winding roller. The top of the placement plate 32 has a placement groove, and a collection plate 33 is provided on the top of the placement plate 32. The top of the collection plate 33 has a collection groove. The cut rust-proof paper is placed into the collection groove on the collection plate 33, and the collection plate 33 is supported and positioned by the placement plate 32.

[0050] Furthermore, such as Figure 1 and Figure 4 As shown, pulleys 34 are movably connected around the bottom of the cutting seat 1. A limit ring 35 is fixedly connected to one side of the cutting seat 1 near the placement plate 32. An anti-slip block is rotatably connected to the inner wall of the limit ring 35.

[0051] To facilitate the transfer of the collection plate 33 containing the rust-proof paper, pulleys 34 are movably connected around the bottom of the cutting seat 1 to facilitate the movement of the collection plate 33. In order to prevent the collection plate 33 from being easily moved due to collision and causing the rust-proof paper to be scattered, the collection plate 33 is limited by the limiting ring 35 and the anti-slip block rotatably connected inside it, together with the placement plate 32.

[0052] Furthermore, such as Figure 5 As shown, a guide rod is fixedly connected to the inner bottom wall of the through groove, the top end of the guide rod passes through the second rack 10 and is fixedly connected to the inner top wall of the through groove, and the outer wall of the clamping plate 7 is provided with anti-slip texture.

[0053] To prevent the clamping plate 7 from shifting during the movement of the gear, a guide rod is fixedly connected to the inner bottom wall of the through groove, and the top of the guide rod passes through the first gear 96 and is fixedly connected to the inner top wall of the through groove to position and guide the movement of the clamping plate 7. The outer wall of the clamping plate 7 is provided with anti-slip texture to ensure stability after clamping the end of the anti-rust paper and to prevent it from slipping and falling off.

[0054] Working principle: Before cutting the rust-proof paper, i.e. when laying the rust-proof paper at startup, the rust-proof paper can be laid on the auxiliary plate 91 and then placed in the clamping frame 5. The second cylinder 6 is then activated to move the clamping plate 7 to clamp and position the end of the rust-proof paper. The drive assembly then moves the rust-proof paper away from the take-up roller 8. At the same time, the first rack 93 partially pops out of the groove 92 under the pressure of the first spring 94. Then, the first gear 96 drives the auxiliary rod to rotate, and the limit block 95 rotates synchronously. Together with the auxiliary plate 91, the rust-proof paper is pressed and positioned. When the rust-proof paper passes through the clamping frame... After the clamping plate 7 is pulled to a certain distance, the first cylinder 3 is activated to drive the cutting blade 4 to move and cut the rust-proof paper. At this time, the cut rust-proof paper ends are pressed by the two limit blocks 95 to counteract the rebound force of the rust-proof paper, so as to prevent the rust-proof paper from scattering due to rebound. Then, the drive assembly drives the clamping frame 5 to move and reset towards the winding roller 8, and pushes the first rack 93 back into the groove 92. The limit blocks 95 rotate and assist in pushing the rust-proof paper into the clamping frame 5, so as to achieve the purpose of automatic feeding into the clamping frame 5. Only initial installation is required. When the take-up roller 8 is manually laid, the anti-rust paper can be automatically pulled and laid through the cooperation of the auxiliary plate 91 and the clamping frame 5. In order to prevent the take-up roller 8 from rotating during cutting, the rotation of the take-up roller 8 is limited. At the same time, to further reduce the impact of the anti-rust paper rebound on the cutting, one end of the transmission rod 18 can be inserted into the positioning holes opened on both sides of the take-up roller 8 during installation. This ensures that the rotation of the take-up roller 8 can be limited through the transmission rod 18. Then, when the drive component moves the anti-rust paper away from the take-up roller 8, the second rack 10 Multiple equally spaced second gears 11, in conjunction with a synchronous belt 17, drive a third gear 16 to rotate. The drive rod 13, through a worm gear 14 and a worm 15, drives a transmission rod 18 to rotate, which in turn drives a take-up roller 8 to rotate. This assists in laying the anti-rust paper. When the clamping frame 5 stops moving, i.e., when cutting is to be performed, the take-up roller 8 is limited in rotation due to the meshing of the gears and racks. This, in conjunction with the positioning mechanism 9, counteracts and mitigates the impact of the anti-rust paper's rebound. It also prevents the take-up roller 8 from rotating during cutting, thus avoiding exceeding the required cutting length.

[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
