[0001] This utility model relates to the technical field of PVC roll slitting machines, specifically to a fine PVC roll slitting machine for medicinal material packaging. Background Technology
[0002] PVC roll slitting machines are commonly used to cut PVC rolls into sheets. The resulting PVC film is then used for packaging medicinal herbs. However, in existing technologies, when the PVC film is applied to the packaging, excess film extends beyond the outer edges of the packaging box. This necessitates further cutting of the excess film after installation, increasing production steps and reducing efficiency. Therefore, a fine PVC roll slitting machine for medicinal herb packaging is proposed. Summary of the Invention

[0017] The following description, in conjunction with the accompanying drawings, further illustrates the fine PVC roll slitting machine for medicinal material packaging according to this utility model.
[0018] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.
[0019] See appendix Figure 1-4 As shown in this embodiment, a fine PVC roll slitting machine for medicinal material packaging includes a slitting base 1, a slitting blade 2 mounted on the slitting base 1, and an eccentric circular drive mechanism 3 that drives the slitting blade 2 to reciprocate and slit to slit the PVC roll. The slitting base 1 is characterized by having a dividing fixed seat 4, several dividing seats 401 slidably mounted on the dividing fixed seat 4, a dividing blade 402 with adjustable direction mounted on the dividing seats 401, and a locking structure 403 that locks the dividing seats 401 and the dividing blade 402 respectively. The dividing fixed seat 4 is also equipped with a scale 5 for precise adjustment of the dividing seats 401. The dividing seats 401 have standard lines corresponding to the scale 5. The dividing blade 402 is precisely adjusted along the scale 5 on the dividing fixed seat 4 by the dividing seats 401. After adjustment, the locking structure 403 is used to lock the blade, thus facilitating precise slitting of the PVC film without secondary cutting, thereby improving production efficiency. The dividing blade 402 can be rotatably mounted on the dividing seat 401, and the locking structure 403 locks it after the dividing blade 402 is adjusted to the correct angle. The number of dividing blades 402 can be adjusted according to the specifications of PVC film dividing. Dividing blades 402 that are not needed beyond the dividing specifications can be adjusted downwards and not used, thus meeting the dividing requirements of different specifications.
[0020] See appendix Figure 3-4As shown, the locking structure 403 includes a first nut 404 and a second nut 405 mounted on the dividing seat 401, and a first screw 406 and a second screw 407 respectively connected to the first nut 404 and the second nut 405 at one end passing through the dividing seat 401 to lock the dividing seat 401 and the dividing blade 402; the dividing blade 402 is provided with an adjusting sleeve 408 for easy fitting onto the first screw 406, and the dividing blade 402 is locked onto the dividing seat 401 as the first screw 406 is tightened; the dividing fixing seat 4 of the dividing seat 401 is provided with an clearance groove 409; one end of the first screw 406 passes through one end of the dividing seat 401 and the dividing fixing seat 4 in sequence. The clearance groove 409 is connected to the first nut 404 at the other end of the dividing seat 401. As the first screw 406 is tightened along the first nut 404, the dividing seat 401 is locked onto the dividing fixing seat 4, thus facilitating the locking of the dividing seat 401. The second screw 407 passes through one end of the dividing seat 401 and the adjusting sleeve 408 on the dividing blade 402 in sequence and is connected to the second nut 405 at the other end of the dividing seat 401. As the second screw 407 is tightened, the dividing blade 402 is locked onto the dividing seat 401. When the second screw 407 is loosened, the dividing blade 402 can rotate the adjusting sleeve 408 along the second screw 407 to adjust the angle, thus facilitating the adjustment and locking of the dividing blade 402.
[0021] See appendix Figure 1 As shown, the eccentric circle drive mechanism 3 includes a rotating shaft 301 rotatably mounted on the slitting base 1, eccentric circles 302 mounted at both ends of the rotating shaft 301, a driven member 303 connected at one end to the slitting blade 2 and movably mounted on the eccentric circle 302 at the other end, and a drive source 305 that drives the rotating shaft 301 to rotate. The drive source 305 drives the rotating shaft 301 to rotate, the rotating shaft 301 drives the eccentric circle 302 to rotate, the eccentric circle 302 drives the driven member 303 to reciprocate up and down, and the driven member 303 drives the slitting blade 2 to reciprocate up and down, thereby facilitating the slitting of the PVC film.
[0022] See appendix Figure 1-2 As shown, the slitting base 1 is also equipped with several guide wheels 101 for guiding the PVC film, a fixed pressure roller 102 connected to the drive source 305, and an adjusting pressure roller 103 corresponding to the fixed pressure roller 102; the adjusting pressure roller 103 is also connected to a cylinder 104 fixed on the slitting base 1; the adjusting pressure roller 103 is driven by the cylinder 104 to move, thereby adjusting the gap between the fixed pressure roller 102 and the fixed pressure roller 102, so as to adapt to the use of PVC films of different thicknesses and expand the range of applications.
[0023] In the process of using this utility model, firstly, the dividing seat 401 drives the dividing blade 402 to make precise adjustments along the scale 5 on the dividing fixed seat 4, so that the standard line on the dividing seat 401 corresponds precisely with the scale 5. After the adjustment is completed, one end of the first screw 406 passes through one end of the dividing seat 401 and the clearance groove 409 on the dividing fixed seat 4 and connects to the first nut 404 at the other end of the dividing seat 401. As the first screw 406 is tightened along the first nut 404, the dividing seat 401 is locked onto the dividing fixed seat 4. Then, the PVC film on the PVC roll passes through the guide wheel 101 on the slitting base 1 and the dividing fixed seat 4. The fixed seat 4 conveys the PVC film between the fixed pressure roller 102 and the adjusting pressure roller 103. The drive source 305 drives the fixed pressure roller 102 to rotate via belt drive. The PVC film is conveyed to the slitting knife 2 by the friction between the fixed pressure roller 102 and the adjusting pressure roller 103. When the PVC film passes through the fixed seat 4, the slitting knife 402 cuts the PVC film. The drive source 305 drives the rotating shaft 301 to rotate. The rotating shaft 301 drives the eccentric circle 302 to rotate. The eccentric circle 302 drives the driven member 303 to move up and down reciprocatingly. The driven member 303 drives the slitting knife 2 to move up and down reciprocatingly, cutting the PVC film. When cutting PVC film of different specifications, the excess cutting blade 402 is rotated to a different angle so that the PVC film is not cut, and the corresponding number of cutting blades 402 are used to cut the PVC film.
[0024] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
