Technical Field

[0001] This utility model relates to the field of playing card packaging technology, specifically a film cutting mechanism for a playing card packaging machine. Background Technology

[0002] Packaging is a crucial step in the production of playing cards. Typically, playing cards are packaged in film to ensure cleanliness and moisture protection. The film cutting mechanism is a key component of playing card packaging machines, and its performance directly affects the packaging efficiency and quality.

[0003] In existing playing card packaging machines, the film cutting mechanism has been found to have a problem: due to the long-term contact between the cutting base and the blade of the cutting knife, grooves are left on it. When the grooves are deep, the film is easily drawn into the grooves during the cutting process, resulting in uneven cuts or even failure to cut due to the film's elasticity. This necessitates disassembling the entire cutting mechanism for grinding or replacement, leading to high maintenance costs.

[0004] Therefore, it is necessary to provide a new film cutting mechanism for playing card packaging machines to solve the above-mentioned technical problems. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figures 1-5 .

[0018] The film cutting mechanism of the playing card packaging machine includes: an outer frame 1, on which fixed ear plates are fixedly installed on both outer walls. Multiple mounting holes are provided on each of the two fixed ear plates to fix the outer frame 1 to the main body of the packaging machine. A cutting cylinder 2 is fixedly installed on the top inner wall of the outer frame 1, and a bearing bar 3 is fixedly installed on its output shaft. Two sliding rods 4 are slidably installed on the bearing bar 3. A cutter box 5 with an open bottom is fixedly installed at the bottom end of the two sliding rods 4. A tension spring 6 is fitted on each of the two sliding rods 4. The top end of the tension spring 6 is fixedly connected to the bearing bar 3, and the bottom end is fixedly connected to the cutter box 5. A cutting blade 8 is provided inside the cutter box 5. A connecting post 7 is fixedly installed at the bottom of the bearing bar 3. The bottom end of the connecting post 7 extends into the cutter box 5 and is fixedly connected to the cutting blade 8. The connecting post 7 is slidably connected to the top of the cutter box 5, and a rubber ring is fixedly installed at the bottom of the cutter box 5. When the output shaft of the cutting cylinder 2 extends, the rubber ring pad 9 will first contact the film and press the film tightly. Then the cutting blade 8 continues to descend, finally cutting the film. On the one hand, it can prevent the instantaneous collision between the cutting blade 8 and the cutting base 13, and on the other hand, it can improve the cutting accuracy and quality. The same cutting table 11 is fixedly installed on the inner walls of both sides of the outer frame 1. A maintenance groove 12 is opened on its top. The cutting base 13 is installed in the maintenance groove 12. The top end face of the cutting base 13 is flush with the top end face of the cutting table 11. Two resting grooves 14 are opened on the top of the cutting table 11. The side of the two resting grooves 14 that are close to each other is connected to the maintenance groove 12. Side connecting pieces 15 are provided in both resting grooves 14. The side of the two side connecting pieces 15 that are close to each other is fixedly connected to the cutting base 13. In addition, a lifting hook is fixedly installed on the top of the two side connecting pieces 15 for easy lifting operation.

[0019] In this embodiment, when the equipment is idle, in order to isolate and protect the cutting blade 8, support plates are fixedly installed on both outer walls of the cutting blade box 5. Guide holes are opened on both support plates, and guide posts are slidably installed in both guide holes. The bottom ends of the two guide posts are fixedly installed with the same sealing cover plate 10. The top of the sealing cover plate 10 contacts the rubber ring gasket 9. The two support plates are threaded with first fastening screws on the opposite sides. The ends of the two first fastening screws abut against the two guide posts respectively. Through the cooperation between the sealing cover plate 10 and the cutting blade box 5, the cutting blade 8 can be wrapped, thereby greatly reducing the adverse effects on the cutting blade 8 and extending its service life.

[0020] In this embodiment, in order to firmly fix the cutting base 13 in the inspection slot 12 and facilitate its subsequent replacement, a clamping cylinder 16 is fixedly installed at the bottom of the cutting table 11. A linkage bar 17 is fixedly installed on its output shaft. Two connecting rods 18 are fixedly installed on the top of the linkage bar 17. The top ends of the two connecting rods 18 pass through the cutting table 11 and are slidably connected to the cutting table 11. A clamping folding rod 19 is fixedly installed on each of the two connecting rods 18. The two clamping folding rods 19 are located above the cutting table 11 and are positioned above it. The bottom end of the cutting table 11 abuts against the two side pieces 15 respectively. The pressing lever 19 applies downward pressure to the side pieces 15, thereby achieving a stable fixing effect on the cutting base 13. In addition, two limiting posts are fixedly installed at the bottom of the cutting table 11. Both limiting posts pass through the linkage bar 17 and are slidably connected to it. A second fastening screw is threaded on one side of the linkage bar 17. The end of the second fastening screw abuts against one of the limiting posts. Through the positioning effect of the second fastening screw, the pressing lever 19 can stably apply downward pressure to the side pieces 15.

[0021] In this embodiment, in order to ensure the stability of the linear lifting of the support bar 3, guide rails are fixedly installed on the inner walls of both sides of the outer frame 1, and guide sliders are slidably installed on both guide rails. The two sides of the support bar 3 are fixedly connected to the two guide sliders respectively.

[0022] In addition, two fixed abutment pieces are fixedly installed on the top inner wall of the outer frame 1, and movable abutment pieces are fixedly installed on the top of the two sliding rods 4. The two movable abutment pieces are in contact with the two fixed abutment pieces respectively. By utilizing the abutment relationship between the two abutment pieces, the cutter box 5 will not move upward when the guide post is inserted upward during the installation of the sealing cover plate 10, which provides convenience for actual operation.

[0023] The working principle of the film cutting mechanism of the playing card packaging machine provided by this utility model is as follows: Before use, the outer frame 1 is fixed to the main body of the packaging machine through the fixed ear plates on both sides of the outer wall to prevent the whole machine from shaking during the cutting process. The main body of the packaging machine will transport the packaging film with the cut to the top of the cutting table 11. The film covers the cutting base 13. Then, rotate the two first fastening screws in the opposite direction to separate the two first fastening screws from the two guide posts respectively, and then the sealing cover 10 can be removed. Once the film is positioned, the clamping cylinder 16 is activated, its output shaft extends and pushes the linkage bar 17 downward; the two connecting rods 18 at the top of the linkage bar 17 move downward simultaneously, driving the two clamping folding rods 19 downward until the bottom end of the clamping folding rod 19 is in close contact with the side piece 15 in the support groove 14. Through the downward pressure of the clamping folding rod 19 on the side piece 15, the cutting base 13 is pressed firmly onto the cutting table 11 to prevent displacement during subsequent cutting. Then, the second fastening screw is tightened. During cutting, the output shaft of the cutting cylinder 2 extends downward, pushing the support bar 3 to descend vertically along the guide rail. The connecting column 7 at the bottom of the support bar 3 moves downward accordingly, driving the cutting blade 8 to move closer to the cutting base 13. During the descent of the support bar 3, the cutting box 5 is connected to the support bar 3 through two sliding rods 4 and also descends under the connection of the tension spring 6. When the rubber ring pad 9 at the bottom of the cutting box 5 contacts the film surface first, the support bar 3 continues to descend. The tension spring 6 is compressed and generates a buffering force, making the cutting box 5 tightly press against the film. Then the cutting blade 8 breaks through the buffer stroke and continues to descend. The blade contacts the film and cooperates with the cutting base 13 to complete the cutting of the film. Among them, the buffering effect of the tension spring 6 can prevent the blade from being damaged due to excessive instantaneous impact force on the cutting blade 8. At the same time, the cooperation between the rubber ring gasket 9 and the sealing cover plate 10 can prevent the "fraying" phenomenon caused by the extensibility of the film during cutting, ensuring a neat cut. After the cutting is completed, the output shaft of the cutting cylinder 2 retracts, which drives the carrier strip 3, the cutter box 5, and the cutting blade 8 to rise and reset synchronously, so that the cut film can be taken out. When the cutting base 13 develops a deep groove due to long-term contact with the cutting blade 8, first reverse the second fastening screw to separate it from the corresponding limit post. Then, start the output shaft of the clamping cylinder 16 to retract, and the connecting rod 18 will rise with the clamping lever 19 to separate it from the side piece 15. Then, directly use the lifting hook to remove the cutting base 13 and take out a new cutting base 13. Place it in the inspection slot 12 and place the side pieces 15 on both sides into the two resting slots 14 respectively. Then, start the output shaft of the clamping cylinder 16 to extend, and the clamping lever 19 can be used again to apply downward pressure to the side piece 15. In addition, when the machine is idle, insert the two guide pins on the sealing cover plate 10 into the corresponding guide holes so that the sealing cover plate 10 abuts against the rubber ring gasket 9, and then tighten the first fastening screw. This will enclose the cutting blade 8 in the cutting blade box 5, which can prevent impurities and moisture in the air from entering the cutting blade box 5 and adversely affecting the cutting blade 8 during the idle period.

[0024] Compared with related technologies, the film cutting mechanism for the playing card packaging machine provided by this utility model has the following beneficial effects: I. This utility model uses the buffering effect of the tension spring 6 to prevent the cutting blade 8 from breaking due to instantaneous impact, and uses the pressure of the rubber ring pad 9 to prevent the film from "fraying" due to its extensibility, thus ensuring neat cuts and improving packaging quality. Second, after the cutting base 13 wears out, this utility model does not require disassembling the entire mechanism. By loosening the second fastening screw and separating the clamping folding rod 19, it can be taken out and replaced with the help of the lifting hook. The operation is convenient and reduces downtime and maintenance costs. Third, when the machine is stopped, the sealing cover 10 of this utility model can wrap the cutting blade 8 inside the cutting blade box 5, isolate impurities and moisture, extend the service life of the cutting blade 8, and reduce equipment failure.
