[0002] The PVC unwinding process of the capsule blister packaging machine is a key link in automated production. It involves continuously conveying the pre-prepared PVC sheet material to the packaging forming area at a constant speed and tension for subsequent processes such as heat sealing, forming and capsule filling. This process requires precise control of the unwinding length and speed of the PVC material to ensure packaging quality and efficiency.

[0003] In the PVC unwinding of the capsule blister packaging machine, a limiter is required to use a punching mechanism to control the length of the PVC sheet during the unwinding process to ensure the accurate use of the packaging material and production efficiency. Although the existing technology has met the user's needs to a certain extent, there are still certain defects in the use process. The specific problems are as follows: The existing limiters are mostly fixed in use or installed with fastening screws. During long-term use, dust, oil and other impurities are easily accumulated on the surface and inside of the limiter. If not cleaned in time, these impurities may affect the performance and life of the limiter, and even cause malfunctions. When cleaning or replacing parts is required, it takes a lot of time and effort to unfasten the fixing device, which increases the complexity and difficulty of maintenance.

[0021] See also Figure 1-4 The PVC unwinding length limiter of the capsule blister packaging machine includes a base plate 1 and a limit frame 8. The top of the base plate 1 is fixedly connected to a fixing seat 2. The front and back sides of the right side of the fixing seat 2 are fixedly connected to the limit plate 6. The outside of the limit plate 6 is fixedly connected to the limit seat 7. The front and back sides of the bottom of the limit frame 8 are fixedly connected to a mounting block 9. The mounting block 9 is clamped in the inner cavity of the limit seat 7. The top and bottom of the inner surface of the limit seat 7 are provided with a placement cavity 17. The inner cavity of the placement cavity 17 is penetrated by a guide rod 18. The surface of the guide rod 18 is provided with a reset spring 19. The inner side of the guide rod 18 is fixedly connected to a limiting block 20. The top and bottom of the mounting block 9 are provided with a limiting groove 14, and the limiting block 20 is clamped in the inner cavity of the limiting groove 14.

[0022] Through the above technical solution, by setting the limit seat 7 and the mounting block 9, the limit frame 8 can be preliminarily positioned, and the reset spring 19 restores the deformation and extends inward when the influence of the force is lost, and drives the guide rod 18 to move inward. The guide rod 18 drives the limit block 20 to move inward, so that the inner side of the limit block 20 is clamped in the inner cavity of the limit groove 14, limiting the mounting block 9, thereby improving the fixing effect of the limit frame 8, and facilitating the subsequent disassembly of the limit frame 8 for inspection or cleaning.

[0023] Specifically, the front side and the back side of the inner side of the fixed seat 2 are movably connected with the card seat 3, the inner side of the card seat 3 is clamped with the unwinding roller 4, the front surface of the fixed seat 2 is fixedly connected with the unwinding motor 5 for driving the card seat 3 and the unwinding roller 4 to rotate, and the output end of the unwinding motor 5 is fixedly connected to the middle end of the front surface of the front card seat 3, the top of the limit frame 8 is fixedly connected with the cylinder 10, the output end of the cylinder 10 is fixedly connected with the blade 11, the bottom of the inner side of the limit frame 8 is fixedly connected with the cutting plate 12, the right side of the limit frame 8 is provided with a displacement sensor 13, and the front and back sides of the inner side of the limit frame 8 are opened. There is a first slide groove 15, and the front and back sides of the blade 11 are fixedly connected with a slider 16. The outer side of the slider 16 is slidably connected to the inner cavity of the first slide groove 15. The inner surface of the limit seat 7 and the front and back sides of the placement cavity 17 are provided with a second slide groove 24. The surface of the guide rod 18 is fixedly connected with a movable plate 23, and the outer side of the movable plate 23 is slidably connected to the inner cavity of the second slide groove 24. The outer side of the guide rod 18 is fixedly connected with a magnetic pull plate 22. The front and back sides of the outer side of the limit seat 7 are inlaid with magnetic blocks 21, and the magnetic blocks 21 and the magnetic pull plates 22 are magnetically connected.

[0024] Through the above technical solution, by setting the movable plate 23 and the second slide groove 24, the smoothness of the guide rod 18 during the up and down movement can be effectively improved. By setting the magnetic block 21 and the magnetic pull plate 22, the guide rod 18 can be fixed, thereby improving the clamping effect between the limit block 20 and the limit groove 14.

[0025] When in use, first pull the magnetic pull plate 22 outward, the magnetic pull plate 22 drives the guide rod 18 to move outward, the guide rod 18 drives the return spring 19 to deform and squeeze outward, then move the limit frame 8 to the left, so that the mounting block 9 is clamped on the inner side of the limit seat 7, and the magnetic pull plate 22 is released. At this time, the return spring 19 recovers its deformation due to the loss of force and extends inward, and drives the guide rod 18 to move inward. The guide rod 18 drives the limit block 20 to move inward, so that the inner side of the limit block 20 is clamped in the inner cavity of the limit groove 14, limiting the mounting block 9, thereby improving the fixing effect of the limit frame 8;

[0026] Before the unwinding process, the PVC sheet is first passed through the inner side of the limit frame 8. The output end of the unwinding motor 5 drives the clamping base 3 and the unwinding roller 4 to rotate to unwind. The unwinding length is monitored and calculated in real time by the displacement sensor 13. When the unwinding length reaches the set value, the output end of the cylinder 10 extends downward and drives the blade 11 to move downward to punch the PVC sheet.

[0027] When the limit frame 8 needs to be disassembled for inspection or cleaning, first pull the magnetic pull plate 22 outward, the magnetic pull plate 22 drives the guide rod 18 to move outward, and the guide rod 18 drives the limit block 20 to move outward, so that the limit block 20 is no longer stuck in the inner cavity of the limit groove 14, and then pull the limit frame 8 to the right so that the mounting block 9 is no longer stuck in the inner cavity of the limit seat 7, which facilitates the rapid disassembly of the limit frame 8 (the above is the working process of the entire device, and the content not described in detail in this manual belongs to the existing technology known to professional and technical personnel in this field).
