Description

Technical Field

[0001] This invention relates to the field of winding and shearing devices, specifically a two-axis winding and shearing machine. Background Technology

[0002] Rewinding is a method of winding continuous products such as films, strips, monofilaments, hoses, and covered wires into a roll. Shearing machines are suitable for metal recycling plants, scrap car dismantling yards, and the smelting and casting industry. They are used for cold shearing and pressing of various shapes of steel and various metal materials, as well as for pressing and molding powdered products, plastics, fiberglass, insulating materials, and rubber. Some materials require winding and shearing processes during processing, and are generally processed using a winding and shearing machine to increase processing efficiency.

[0003] For example, the Chinese authorized patent CN214612567U, "A Cutting Device for Leather Processing," describes a cutting device that adjusts the distance between the cutting seam base and the slide, then fixes it through a first positioning post passing through a first limiting hole. This allows users to place one end of the leather under the pressure plate and pull the other end to the upper end of the cutting seam base after adjusting the distance for cutting, ensuring standardized segment lengths without requiring measurement, thus improving cutting efficiency. Secondly, the sliding post is first adjusted inside the second sliding groove to adjust the cut leather size, then fixed through the second positioning post passing through the second limiting hole. A motor drives a winding rod to rotate, allowing the cut leather to be placed on the surface of the winding rod for easy storage. To retrieve the wound leather, the sliding post slides inside the second sliding groove, allowing the winding rod to slide out from inside the sliding post, facilitating disassembly and reassembly of the leather.

[0004] While the aforementioned existing technology can perform winding processing, the device only has one rotating shaft, which means that the next winding cannot be performed immediately after winding is completed, and a replacement is required before the next winding can be performed, thus affecting processing efficiency. At the same time, after the shearing device cuts the material, there is no limiting function for the material, which means that the material needs to be repositioned before the next winding and shearing, causing inconvenience to subsequent processing and affecting processing efficiency. Therefore, it does not meet the current requirements. In response, we propose a two-axis winding and shearing machine. Summary of the Invention

[0005] The purpose of this invention is to provide a two-axis winding and shearing machine to solve the problems mentioned in the background art, such as low winding efficiency of the shearing device and lack of limiting for material breakage after winding and shearing, which requires repositioning and affects subsequent processing.

[0017] Preferably, the end of the pull rod located inside the storage cavity is provided with a first handle.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention features an L-shaped fixing frame on the rear side of the upper part of the base, and a rotating seat on one side below the L-shaped fixing frame. After the user finishes winding the material, activating the first servo motor causes the rotating seat to rotate the wound take-up drum, moving the other unwound take-up drum directly below the L-shaped fixing frame. This allows for quick rewinding without waiting for replacement, making it convenient to use. Simultaneously, by reaching into the storage cavity and pulling the first handle, the user can move the push block outwards, releasing the pressure on the limiting block. At this point, the first return spring pulls the limiting block out of the limiting groove, releasing the fixing of the take-up drum. The user can then rotate the take-up drum 90 degrees with their other hand and forcefully pull it out from outside the replacement shaft, allowing for replacement of the unwound take-up drum. The entire operation requires only pulling the first handle, making it convenient and quick to use, facilitating daily operations and improving processing efficiency.

[0020] 2. This invention features shearing boxes on the front and rear sides of the upper base. When shearing is required after winding, the cylinder is activated to move the blade mounting seat downwards, thus shearing the material. The downward movement of the blade mounting seat causes the lower pressure block to move downwards synchronously via the connecting rod, thereby squeezing the extrusion seat and causing it to move downwards synchronously as well. After the extrusion seat moves downwards, it is limited by a locking block. At this time, the roller at the lower end of the extrusion seat and the roller at the front of the upper base squeeze the material, thus fixing it in place. When the cylinder moves the blade mounting seat and the lower pressure block upwards synchronously, the elasticity of the fourth return spring allows the locking block to continuously limit the extrusion seat, ensuring that the upward movement of the shearing blade does not cause the material to shift. At this time, a hand can be inserted from the rear side of the shearing box to pull one end of the material. The rolling of the rollers can pull the material out, thus fixing one end of the material to the outer wall of the winding drum. This effectively avoids the problem of needing to reposition the material after shearing, which affects processing efficiency. At this time, simply pulling the second handle releases the limiting fixation of the extrusion seat, making it convenient to use.

[0021] 3. This invention features a set of protrusions on the front sides of both sides of the base. When a user needs to process the material alone, after pulling out the second handle, the user can rotate the locking block through the damping shaft to make the locking block engage with the slots at the top and bottom of the second handle. This locking block limits the second handle, allowing the user to easily pull the other handle, increasing practicality, meeting the needs of single-person use, and making it convenient to use.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Please see Figure 1-10 An embodiment of the present invention provides a two-axis winding and shearing machine, including a base 1, a shearing box 3 is provided on the front side of the upper end of the base 1, an L-shaped fixing frame 2 is provided on the rear side of the upper end of the base 1, a rotating seat 7 is provided on one side below the L-shaped fixing frame 2, and a first rotating shaft 6 is fixedly provided on both the upper and lower ends of the rotating seat 7, and one of the first rotating shafts 6 is rotatably connected to the L-shaped fixing frame 2.

[0035] The system also includes a replacement shaft 10, which is located on both sides of the rotating seat 7. The replacement shaft 10 has a first transmission cavity 12 inside. A set of first guide rods 15 is provided on both the front and rear sides of the first transmission cavity 12, with two rods in each set. A first connecting block 16 is slidably mounted on the outside of each first guide rod 15. A limit block 13 is provided between each first guide rod 15, and the limit blocks 13 are welded and fixed to the first connecting blocks 16. One end of each limit block 13 extends through and to the outside of the first transmission cavity 12, and the limit blocks 13 are slidably engaged with the first transmission cavity 12. The first transmission cavity 12 is equipped with a pull rod 19 inside each of the two chambers. A storage cavity 20 is opened on one side of the first transmission cavity 12. One end of the pull rod 19 passes through the first transmission cavity 12 and extends into the storage cavity 20. The pull rod 19 is slidably engaged with the first transmission cavity 12 and the storage cavity 20. The outer wall of the replacement shaft 10 is equipped with a winding drum 11. The winding drum 11 is slidably engaged with the replacement shaft 10. Three equally spaced limiting grooves 14 are opened at the front and rear ends of the winding drum 11. The limiting grooves 14 are adapted to the end of the limiting block 13 located outside the first transmission cavity 12.

[0036] It also includes a second transmission cavity 33, which is opened at the front end of both sides inside the shear box 3. A third guide rod 34 is welded to one side inside the second transmission cavity 33. A third connecting block 35 is slidably arranged on the outside of the third guide rod 34, and one end of the third connecting block 35 extends to the outside of the second transmission cavity 33. A second fixing block 38 is arranged on one side of the lower end inside the second transmission cavity 33, and the second fixing block 38 is slidably engaged with the second transmission cavity 33. A limit pull block 37 is fixedly arranged at the middle position inside the second fixing block 38, and both ends of the limit pull block 37 extend to the outside of the second fixing block 38. One end of the limit pull block 37 penetrates and extends to the outside of the second transmission cavity 33, and the limit pull block 37 is slidably engaged with the second transmission cavity 33.

[0037] In use, after one winding is completed, the shearing blade 28 can be cut by starting the cylinder 26. At this time, the rotating seat 7 can be rotated by starting the first servo motor 4 and connecting it with the reduction gearbox 5, so that the wound winding drum 11 can be moved out of the L-shaped fixing frame 2 and the unwound winding drum 11 can be moved into the L-shaped fixing frame 2, so that the next winding can begin, which improves the efficiency of work. At the same time, the user can pull the first handle 21 to move the pull rod 19. The pull rod 19 will drive the push block 18 to move synchronously to release the compression limit of the limit block 13. Under the elastic restoration of the first return spring 17, the limit block 13 can be moved out of the limit groove 14, so that the connection between the winding drum 11 and the replacement shaft 10 can be quickly released, and the winding drum 11 can be quickly replaced, which is convenient to use.

[0038] Please see Figure 6, Figure 7 and Figure 10 Four equally spaced push blocks 18 are welded to the outer wall of one end of the pull rod 19 inside the first transmission cavity 12. Four first fixing blocks 25 are welded to the inside of the first transmission cavity 12, and each first fixing block 25 is penetrated by the pull rod 19. Second connecting blocks 23 are welded to the upper and lower ends of each push block 18. Second guide rods 22 are provided above and below each push block 18, and both ends of the second guide rods 22 are fixedly connected to the first fixing blocks 25 and the first transmission cavity 12. Each second guide rod 22 penetrates the second connecting block 23, and the second connecting blocks 23 slide against the second guide rod 22. The second guide rod 22 is fitted with a second return spring 24 on one side of its outer side. One end of the second return spring 24 is connected to the first fixing block 25, and the other end of the second return spring 24 is connected to the second connecting block 23 or the first transmission cavity 12. The elasticity of the second return spring 24 can cause the push block 18 to squeeze and push the limiting block 13, thereby allowing the limiting block 13 to be inserted into the limiting groove 14 and limiting the limiting block 13, preventing the limiting block 13 from moving out of the limiting groove 14, and ensuring the firm connection between the replacement shaft 10 and the winding drum 11.

[0039] Please see Figure 7 Each of the first guide rods 15 is fitted with a first return spring 17. One end of each first return spring 17 is connected to the first transmission cavity 12, and the other end of each first return spring 17 is connected to the first connecting block 16. The elastic action of the first return spring 17 can drive the limiting block 13 to move out of the limiting groove 14, which makes it easier to release the fixing of the replacement shaft 10 and the winding drum 11.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A cylinder 26 is installed at the upper end of the shearing box 3. A blade mounting seat 27 is installed at the output end of the cylinder 26. A shearing blade 28 is installed at the lower end of the blade mounting seat 27. A lower pressure block 30 is installed in front of the blade mounting seat 27. The lower pressure block 30 and the blade mounting seat 27 are connected by three equally spaced connecting rods 29. A pressing seat 31 is installed below the lower pressure block 30. Both ends of the pressing seat 31 are connected to the end of the third connecting block 35 located outside the second transmission cavity 33. Two rollers 32 are rotatably installed at the lower end of the pressing seat 31 and the front side of the upper end of the base 1. The rollers 32 are made of rubber material to avoid wear on the material.

[0041] Please see Figure 8A third return spring 36 is fitted on the upper side of the outer side of the third guide rod 34. One end of the third return spring 36 is connected to the second transmission cavity 33, and the other end of the third return spring 36 is connected to the third connecting block 35. The elastic action of the third return spring 36 can drive the extrusion seat 31 to move up automatically, which is convenient for the next winding.

[0042] Please see Figure 9 Each of the limiting pull blocks 37 located inside the second transmission cavity 33 is fitted with a fourth return spring 39 on the outside of one end. One end of the fourth return spring 39 is connected to the second fixing block 38, and the other end of the fourth return spring 39 is connected to the second transmission cavity 33. The elastic action of the fourth return spring 39 can move the limiting pull block 37 to the top of the third connecting block 35 and keep it fixed, thereby completing the fixation of the limiting pull block 37 and preventing the movement of the pressing seat 31.

[0043] Please see Figure 1 , Figure 2 , Figure 3 and Figure 9 Each of the limiting pull blocks 37 located outside the second transmission cavity 33 is provided with a second handle 40. The upper and lower ends of the second handle 40 are provided with slots 44. The upper and lower ends of the second handle 40 are provided with protrusions 41, and the protrusions 41 are welded and fixed to the base 1. Each side of the protrusions 41 is provided with a locking block 42, and the locking block 42 is adapted to the slot 44. The locking block 42 and the protrusions 41 are connected by a damping shaft 43. The second handle 40 is designed to allow the user to pull the limiting pull block 37 to release the fixation of the third connecting block 35. After the locking block 42 is inserted into the slot 44, it can limit the second handle 40, making it easier for the user to pull the other side of the second handle 40.

[0044] Please see Figure 4 The first servo motor 4 is installed on the rear side inside the base 1. The gearbox 5 is installed behind the first servo motor 4. The gearbox 5 is connected to the first rotating shaft 6 through a coupling. The output end of the first servo motor 4 is connected to the gearbox 5 through a coupling. The first servo motor 4 provides power for the position change of the two replacement shafts 10 without manual rotation, which is convenient and quick. At the same time, the gearbox 5 can prevent the rotating seat 7 from rotating too fast.

[0045] Please see Figure 2 The rotating base 7 has two sides equipped with second servo motors 8. The output ends of the second servo motors 8 are all connected to the second rotating shafts 9 through couplings. One end of each second rotating shaft 9 is fixedly connected to the replacement shaft 10. The second servo motors 8 provide power for the rotation and winding of the winding drum 11.

[0046] Please see Figure 3 , Figure 4 , Figure 5 and Figure 7 The lever 19 is provided with a first handle 21 at one end inside the storage cavity 20. The first handle 21 is designed to facilitate the user to pull the lever 19.

[0047] Working principle: In use, the material to be wound is passed through the shearing box 3 and fixed to the outer wall of the winding drum 11 below the L-shaped fixing frame 2. The second servo motor 8 is started, and the changing shaft 10 is rotated under the transmission of the coupling. The changing shaft 10 drives the winding drum 11 to rotate synchronously, thereby winding the material. When it is time to stop winding, the cylinder 26 is started. The output end of the cylinder 26 drives the blade mounting seat 27 to move down. The blade mounting seat 27 drives the shearing blade 28 to shear the material. When the blade mounting seat 27 moves down, it drives the three connecting rods 29 to move down synchronously. The connecting rods 29 drive the lower pressure block 30 to move down synchronously. The lower pressure block 30 will move downward. When the extrusion seat 31 is compressed, the third connecting blocks 35 on both sides of the extrusion seat 31 will move down synchronously inside the second transmission cavity 33 and stretch the third return spring 36. When the third connecting blocks 35 move down, they will compress and push the limiting pull block 37. When the shearing blade 28 cuts the material, the third connecting blocks 35 move to the bottom of the limiting pull block 37. At this time, under the elastic action of the fourth return spring 39, the limiting pull block 37 will return to its original position, thereby limiting the third connecting blocks 35 and preventing the third connecting blocks 35 from moving up. This can limit the extrusion seat 31. At this time, the extrusion seat 31 will compress the material through the roller 32 to prevent the material from shifting position.

[0048] After the material is cut, the cut end can be wound onto the outer wall of the take-up drum 11 by rotating the replacement shaft 10. At this time, the first servo motor 4 can be started to rotate the rotating seat 7, so that the other unwound take-up drum 11 can be moved to the underside of the L-shaped fixing frame 2 for the next winding. At the same time, the gearbox 5 can prevent the rotating seat 7 from rotating too fast. After the wound take-up drum 11 is moved out of the underside of the L-shaped fixing frame 2, the user can put his hand into the inside of the storage cavity 20 and grab the first handle 21 and pull it outward. The first handle 21 will drive the pull rod 19 to move synchronously. The pull rod 19 will drive the push block 18 to move synchronously. The movement of the push block 18 will compress the second return spring 24. At this time, the movement of the push block 18 will release the compression limit on the limit block 13. Under the elastic recovery action of the spring 17, the limiting block 13 can be moved out of the limiting groove 14 through the first connecting block 16, thereby releasing the connection and fixation between the take-up drum 11 and the replacement shaft 10. With the other hand, the take-up drum 11 can be rotated 90 degrees and then pulled out from the outer wall of the replacement shaft 10. Then, the new take-up drum 11 is reinstalled back onto the outer wall of the replacement shaft 10 according to the above steps. And through the elastic recovery of the second return spring 24, the push block 18 is pressed and pushed again to make the limiting block 13 re-enter the limiting groove 14, thus quickly completing the replacement of the take-up drum 11. The entire replacement can be achieved by simply pulling the first handle 21, and the replacement can be carried out simultaneously with the next winding without delaying the winding operation, which greatly improves the processing efficiency.

[0049] When the next winding begins, cylinder 26 moves upward. This upward movement of cylinder 26 synchronously moves blade mounting seat 27 upward, allowing the lower pressure block 30 to release its restriction on the extrusion seat 31. However, due to the restriction of the limiting pull block 37, the extrusion seat 31 continues to maintain its extrusion state on the material, preventing material displacement when the shearing blade 28 moves upward, thus improving the positioning effect. After the shearing blade 28 moves upward, reach your hand from the rear of the shearing box 3, grasp one end of the material, and pull it out. The rolling of the roller 32 allows the material to be smoothly pulled. After fixing one end of the material to the outer wall of the unwound winding drum 11, you can grasp the second handle 40 to pull. When the second handle 40 is pulled, the limiting block 37 moves synchronously, thereby releasing the limiting of the third connecting block 35. Under the elastic action of the third return spring 36, the third connecting block 35 can move the pressing seat 31 upward, so that it can be used for the next winding. At the same time, when the second handle 40 is pulled, the user can rotate the locking block 42 through the damping shaft 43, so that the locking block 42 can be locked into the slots 44 opened at the upper and lower ends of the second handle 40, thereby limiting the second handle 40. This makes it easier for the user to pull the second handle 40 on the other side, so that one person can complete the operation, which is very practical.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
