Description

Technical Field

[0001] This application relates to the field of packaging bag processing equipment technology, and in particular to a packaging bag cutting machine. Background Technology

[0002] As a key processing piece of equipment, the performance of a packaging bag cutting machine directly affects the production efficiency and quality of packaging bags. With the rapid development of the packaging industry, the market's demand for packaging bags in terms of type, specifications, and production efficiency is becoming increasingly diversified and sophisticated. This places higher demands on the automation level, processing precision, and reliability of packaging bag cutting machines. An efficient and stable cutting machine ensures that packaging bags are dimensionally accurate and have clean cuts during the cutting process, thus meeting the usage standards of subsequent packaging stages. Therefore, continuously optimizing the structural design and functional characteristics of cutting machines is of significant practical importance.

[0003] However, in existing technologies, the cutting tools in the dividing machine are usually fixed with multiple bolts, which has certain shortcomings when repairing or replacing the cutting tools. Because it is necessary to repeatedly disassemble and install multiple bolts, this process often consumes a lot of time and effort. Especially in large-scale production scenarios, frequent tool maintenance will lead to extended production line downtime, which will seriously reduce production efficiency and increase the production costs of enterprises. Summary of the Invention

[0004] Technical problems to be solved

[0005] The purpose of this application is to provide a packaging bag dividing machine that enables rapid fixing and disassembly of the cutter body without the need for repeated disassembly and installation of multiple bolts, significantly shortening the cutter maintenance time and improving production efficiency, thus solving the problems mentioned in the background art.

[0006] This application provides a packaging bag dividing machine with the following technical solution: It includes a frame, a base fixedly mounted on the upper side of the frame, a tool mounting bracket on the inner side of the base, a tool body mounted on the inner side of the tool mounting bracket, and a limiting component on the outer side of the tool mounting bracket. The limiting component includes two internally threaded sleeves rotatably connected to the inner side of the tool mounting bracket. Each of the two internally threaded sleeves has a threaded rod threadedly connected to its inner side. One end of each of the two threaded rods is fixedly connected to a pressure plate. A rubber sleeve is fixedly connected to the side of the pressure plate near the tool body. An extension plate is fixedly connected to the outer side of the tool mounting bracket, and a first fixed post is fixedly connected to the outer side of the extension plate. A drive motor is located at the bottom of the frame, and a turntable is fixedly connected to the output end of the drive motor. A second fixed post is fixedly connected to the outer side of the turntable, and a connecting rod is rotatably connected to the outer side of the second fixed post. The end of the connecting rod away from the second fixed post is rotatably connected to the outer side of the first fixed post. A conveying device is fixedly mounted on the upper side of the frame, and a rubber roller is fixedly mounted on the inner side of the base.

[0007] By adopting the above technical solution, and by setting the internal threaded sleeve in the limiting component to be threadedly engaged with the threaded rod, the internal threaded sleeve can be rotated to drive the threaded rod to move the pressure plate. The rubber sleeve on the pressure plate can tightly fit the tool body and squeeze and fix the tool body, thereby realizing the quick fixing and disassembly of the tool body without the need to repeatedly disassemble and install multiple bolts, which greatly shortens the tool maintenance time, improves production efficiency, and reduces the enterprise's production costs.

[0008] Preferably, two symmetrical guide rails are fixedly installed on the inner side of the base, and the outer side of the tool mounting bracket is slidably connected to the inner side of the guide rails.

[0009] By adopting the above technical solution, the guide rail can provide stable guidance for the movement of the tool mounting bracket, enabling the tool mounting bracket to move precisely vertically inside the base, making the cutting of the tool body more stable and accurate.

[0010] Preferably, the limiting assembly further includes two support frames fixedly connected to the outside of the tool mounting bracket, worm gears fixedly connected to the outside of the two internally threaded sleeves, and a rotating shaft rotatably connected to the inside of the two support frames. Two worms are fixedly connected to the outside of the rotating shaft, and the worms mesh with the worm gears.

[0011] By adopting the above technical solution, the support frame supports the rotation of the shaft. The worm gear on the outside of the shaft meshes with the worm wheel on the outside of the internal threaded sleeve. At this time, rotating the shaft can simultaneously drive the two internal threaded sleeves to rotate, thereby achieving synchronous adjustment of the two threaded rods. This ensures that the pressure plate evenly presses the tool body, improving the stability of tool fixation and the convenience of operation.

[0012] Preferably, one end of one of the support frames is rotatably mounted with a handle, the rotating end of the handle is fixedly connected to one end of the rotating shaft, and the outer side of the handle is provided with anti-slip texture.

[0013] By adopting the above technical solution, the rotating handle can easily drive the rotating shaft to rotate, thereby controlling the fixing or loosening of the tool body by the limiting component. At the same time, the anti-slip texture increases the friction between the handle and the hand, making the operation more effortless and stable.

[0014] Preferably, two positioning blocks are fixedly connected to the inner side of the tool mounting bracket, and two through holes corresponding to the positioning blocks are opened on the outer side of the tool body, with the outer side of the positioning blocks inserted into the inner side of the through holes.

[0015] By adopting the above technical solution, the tool body is precisely installed on the positioning block through the through hole, which can quickly and accurately position and install the tool body, ensuring that the tool body reaches the predetermined position quickly and accurately during installation, reducing the alignment time during the installation process, and improving the efficiency and accuracy of tool installation.

[0016] Preferably, a fixing frame is fixedly connected to the outside of the drive motor, and the outside of the fixing frame is fixedly connected to the bottom surface of the frame.

[0017] By adopting the above technical solution, the aforementioned mounting bracket securely mounts the drive motor on the bottom surface of the frame, enhancing the stability of the drive motor during operation.

[0018] Preferably, a barrier beam is fixedly connected to the upper side of the frame, and a placement plate is fixedly connected to the upper side of the frame, with the placement plate located between the barrier beam and the conveying device.

[0019] By adopting the above technical solution, the barrier beam can promptly block the cut products, causing them to detach from the conveyor track and fall onto the adjacent placement plate. This makes the product collection process more automated, effectively prevents products from scattering, and improves the orderliness and operational safety of the production process.

[0020] Preferably, a drive device is installed inside the base, and the output end of the drive device is fixedly connected to one end of the rubber roller.

[0021] By adopting the above technical solution, the driving device drives the rubber roller to rotate, and the rubber roller can smoothly convey the packaging bag to be cut, ensuring that the packaging bag maintains a stable conveying state.

[0022] Beneficial effects

[0023] This packaging bag cutting machine utilizes the interaction between an internal threaded sleeve and a threaded rod, along with a worm gear transmission structure, to drive the internal threaded sleeve to rotate. This, in turn, drives the threaded rod to move the pressure plate. The rubber sleeve on the pressure plate tightly fits against the cutter body, compressing and fixing it. This allows for rapid fixing and disassembly of the cutter body, eliminating the need for repeated disassembly and installation of multiple bolts. This significantly reduces cutter maintenance time, improves production efficiency, and lowers enterprise production costs. Furthermore, the positioning block engages with the through hole in the cutter body, ensuring precise and efficient installation of the cutter body and further enhancing the efficiency of cutter assembly and disassembly.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0032] Example 1: A packaging bag cutting machine, please refer to Figure 1 , Figure 4 and Figure 5The system includes a frame 1, a base 2 fixedly mounted on the upper side of the frame 1, a tool mounting bracket 4 disposed on the inner side of the base 2, a tool body 6 mounted on the inner side of the tool mounting bracket 4, and a limit assembly 5 disposed on the outer side of the tool mounting bracket 4. The limit assembly 5 includes two internally threaded sleeves 501 rotatably connected to the inner side of the tool mounting bracket 4. A threaded rod 503 is threadedly connected to the inner side of each of the two internally threaded sleeves 501. One end of each of the two threaded rods 503 is fixedly connected to a pressure plate 504. A rubber sleeve 505 is fixedly connected to the side of the pressure plate 504 near the tool body 6. The limit assembly 5 also includes two support brackets 506 fixedly connected to the outer side of the tool mounting bracket 4. A worm gear 502 is fixedly connected to the outer side of the two internally threaded sleeves 501. A rotating shaft 507 is rotatably connected to the inner side of the two support brackets 506. Two worms 508 are fixedly connected to the outer side of the rotating shaft 507. The worm gear 508 meshes with the worm wheel 502, and the support frame 506 supports the rotation of the rotating shaft 507. The worm 508 on the outside of the rotating shaft 507 meshes with the worm wheel 502 on the outside of the internal threaded sleeve 501. At this time, rotating the rotating shaft 507 can simultaneously drive the two internal threaded sleeves 501 to rotate, realizing the synchronous adjustment of the two threaded rods 503, ensuring that the pressure plate 504 evenly presses the tool body 6, improving the stability of tool fixation and the convenience of operation. One end of one of the support frames 506 is rotatably mounted with a handle 509. The rotating end of the handle 509 is fixedly connected to one end of the rotating shaft 507. The outer side of the handle 509 is provided with anti-slip texture. Rotating the handle 509 can easily drive the rotating shaft 507 to rotate, thereby controlling the fixing or loosening of the tool body 6 by the limiting component 5. At the same time, the anti-slip texture increases the friction between the handle 509 and the hand, making the operation more effortless and stable.

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 Two symmetrical guide rails 3 are fixedly installed on the inner side of the base 2. The outer side of the tool mounting bracket 4 is slidably connected to the inner side of the guide rails 3. The guide rails 3 provide stable guidance for the movement of the tool mounting bracket 4, enabling the tool mounting bracket 4 to move accurately and vertically within the base 2, making the cutting of the tool body 6 more stable and precise. An extension plate 8 is fixedly connected to the outer side of the tool mounting bracket 4, and a first fixing post 9 is fixedly connected to the outer side of the extension plate 8. A drive motor 11 is provided at the bottom of the frame 1, and the output end of the drive motor 11 is fixedly connected to... A turntable 12 is connected to the machine. A second fixed column 13 is fixedly connected to the outer side of the turntable 12. A connecting rod 10 is rotatably connected to the outer side of the second fixed column 13. One end of the connecting rod 10 away from the second fixed column 13 is rotatably connected to the outer side of the first fixed column 9. A conveying device 14 is fixedly installed on the upper side of the frame 1. The conveying device 14 includes a frame, a drive motor, a drive roller, a driven roller, and a transmission belt. It can convey the cut packaging bags and improve the automation of the cutting machine. A rubber roller 18 is fixedly installed on the inner side of the base 2.

[0034] Example 2: A packaging bag cutting machine, please refer to Figure 1 , Figure 2 and Figure 5 Two positioning blocks 7 are fixedly connected to the inner side of the tool mounting bracket 4. Two through holes corresponding to the positioning blocks 7 are opened on the outer side of the tool body 6. The outer side of the positioning blocks 7 is inserted into the inner side of the through holes. The tool body 6 is precisely installed on the positioning blocks 7 through the through holes, which can quickly and accurately position and install the tool body 6, ensuring that the tool body 6 quickly and accurately reaches the predetermined position during installation, reducing the alignment time during the installation process, and improving the efficiency and accuracy of tool installation. A fixing bracket 17 is fixedly connected to the outer side of the drive motor 11. The outer side of the fixing bracket 17 is fixedly connected to the bottom surface of the frame 1. The fixing bracket 17 securely installs the drive motor 11 on the bottom surface of the frame 1, enhancing the stability of the drive motor 11 during operation. For stability, a barrier beam 15 is fixedly connected to the upper side of the frame 1, and a placement plate 16 is also fixedly connected to the upper side of the frame 1. The placement plate 16 is located between the barrier beam 15 and the conveying device 14. The barrier beam 15 can promptly block the cut products, causing them to leave the conveying track of the conveying device 14 and fall onto the adjacent placement plate 16. This makes the product collection process more automated, effectively prevents products from scattering, and improves the orderliness and operational safety of the production process. A drive device is installed inside the base 2. The output end of the drive device is fixedly connected to one end of the rubber roller 18. The drive device drives the rubber roller 18 to rotate, and the rubber roller 18 can smoothly convey the packaging bags to be cut, ensuring that the packaging bags maintain a stable conveying state.

[0035] The implementation principle of this application embodiment is as follows: When using the packaging bag dividing machine, firstly, the cutter body 6 is installed inside the cutter mounting bracket 4. The positioning block 7 is used to cooperate with the through hole on the cutter body 6 to ensure that the cutter body 6 is installed in an accurate position. Then, the rotating handle 509 is rotated, which drives the rotating shaft 507 to rotate. The worm gear 508 on the rotating shaft 507 meshes with the worm wheel 502, driving the internal threaded sleeve 501 to rotate. The internal threaded sleeve 501 drives the pressure plate 504 to move through the threaded rod 503, so that the rubber sleeve 505 on the pressure plate 504 presses the cutter body 6, completing the fixation of the cutter. After that, the drive motor 11 drives the turntable 12 to rotate, thereby driving the second fixed column 13 on the outer side of the turntable 12 to perform circumferential motion. At this time, the first fixed column 13 on the extension plate 8 is connected to the connecting rod 10. The fixed column 9 is rotatably connected, thereby converting the circular motion of the second fixed column 13 into the up-and-down reciprocating sliding of the tool mounting frame 4. During the sliding process of the tool mounting frame 4, the rubber roller 18 rotates under the action of the driving device, driving the packaging bag to be conveyed to the bottom of the tool body 6 in real time. After that, the cut packaging bag falls onto the conveying device 14 under the action of inertia. Then, the conveying device 14 smoothly conveys the cut packaging bag. After that, the cut product is blocked by the barrier beam 15 and falls onto the placement plate 16, realizing automated collection. Finally, when it is necessary to replace or repair the tool body 6, the handle 509 is rotated in the opposite direction to release the pressure plate 504 from the tool body 6, so that the tool body 6 can be easily disassembled. The whole process does not require the removal of multiple bolts, which greatly improves the efficiency of tool maintenance and reduces the downtime of the production line.
