DETAILED DESCRIPTION

[0027] Embodiment 1

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a packaging film clamping mechanism includes a left bracket 1 and a right bracket 2, and the left bracket 1 and the right bracket 2 are both provided with a vertical slider 3, a connecting rod assembly 4 and a driving assembly 5, the connecting rod assembly 4 is rotatably connected to the vertical slider 3, one end of the connecting rod assembly 4 is provided with a roller 6 for clamping the packaging film 27, and the other end of the connecting rod assembly 4 is rotatably connected to the driving assembly 5, and the left bracket 1 and / or the right bracket 2 are provided with a limiting mechanism 7 for limiting the vertical slider 3 from sliding upward or downward.

[0029] The packaging film 27 is clamped by the roller 6 on the connecting rod assembly 4. Since the connecting rod assembly 4 is rotatably connected to the vertical slider 3, the vertical slider 3 can be limited by the limit mechanism 7 to slide upward or downward, thereby ensuring that the connecting rod assembly 4 does not erroneously operate the vertical slider 3 during rotation, ensuring that the roller 6 on the connecting rod assembly 4 can stably clamp the packaging film 27, and ensuring the safety performance of the clamped packaging film 27 during the lifting and lowering process. Secondly, the driving assembly 5 is arranged at the other end of the connecting rod assembly 4, so that the driving assembly 5 contracts and drives the connecting rod assembly 4 to descend, so that the roller 6 clamps the packaging film 27, and the driving assembly 5 extends and drives the connecting rod assembly 4 to rise to realize the lifting of the packaging film 27. The control sensitivity is high, the structure is simple, and the driving effect is good. The limit mechanism 7 is arranged on the left bracket 1 and / or the right bracket 2. The number of installation of the limit mechanism 7 cannot be set according to the actual installation requirements. The practical performance is good. The left bracket 1 and the right bracket 2 can ensure the stability of the entire packaging film 27 clamping mechanism, which is convenient for installation on the cotton picker.

[0030] The connecting rod assembly 4 includes a first connecting rod mechanism 8 and a second connecting rod mechanism 9, and the first connecting rod mechanism and the second connecting rod mechanism are both provided with the roller 6. The first connecting rod mechanism 8 and the second connecting rod mechanism 9 are rotatably connected to the vertical slider 3, and the first connecting rod mechanism and the second connecting rod mechanism are both rotatably connected to the driving assembly 5, which can realize the synchronous movement of the first connecting rod assembly 4 and the second connecting rod assembly 4, and can ensure the stability of the packaging film 27 when clamping.

[0031] The first connecting rod mechanism 8 and the second connecting rod mechanism 9 both include an upper connecting rod 10 and a lower connecting rod 11, one end of the upper connecting rod 10 is connected to the driving assembly 5, and the other end of the upper connecting rod 10 is rotatably connected to one end of the lower connecting rod 11, the middle part of the lower connecting rod 11 is rotatably connected to the vertical slider 3, and the other end of the lower connecting rod 11 is rotatably connected to the roller 6, and the rising and falling of the roller 6 are realized by the linkage of the upper connecting rod 10 and the lower connecting rod 11. The structure is simple and the installation and disassembly are convenient. The left bracket 1 and the right bracket 2 are both provided with a vertical slide groove 12, and the vertical slider 3 is arranged in the vertical slide groove 12. The vertical slider 3 is provided with a first rotating shaft 13 connected to the lower connecting rod 11, and the first rotating shaft 13 is provided with a first spacer. The vertical slide groove 12 can ensure the straightness of the sliding of the vertical slider 3, ensure the stability of the rotation of the lower connecting rod 11, and improve the clamping force.

[0032] The driving assembly 5 includes a hydraulic cylinder 15 and a second rotating shaft 16, and the hydraulic cylinder 15 includes a piston rod 17. The second rotating shaft 16 is fixedly connected to the piston rod 17. The upper connecting rod 10 is rotatably connected to the second rotating shaft 16, and a second spacer is provided on the second rotating shaft 16. The left bracket 1 and the right bracket 2 are both provided with a vertical guide groove 14 for the second rotating shaft 16 to slide. The driving assembly 5 is configured as a hydraulic cylinder 15 and a second rotating shaft 16. The lifting and lowering of the upper connecting rod 10 are driven by the lifting and lowering of the hydraulic cylinder 15 to ensure the rotation efficiency of the upper connecting rod 10. The second spacer can realize the separation of the upper connecting rod 10, and can realize that the two upper connecting rods 10 can rotate freely. The setting of the vertical guide groove 14 can ensure the straightness of the lifting and lowering of the second rotating shaft 16, and can prevent the connecting rod assembly 4 from being misaligned.

[0033] The limiting mechanism 7 includes a mounting sleeve 18 and a limiting column 19 movably connected in the mounting sleeve 18. The vertical slider 3 is provided with an upper limit hole 20 and a lower limit hole 21 respectively matched with the limiting column 19. A compression spring 22 for resetting the limiting column 19 is also provided between the mounting sleeve 18 and the limiting column 19. The mounting sleeve 18 can realize the rapid installation and fixation of the limiting column 19, and can ensure the straightness of the sliding of the limiting column 19. Secondly, the limiting column 19 is extended into the upper limit hole 20 and the lower limit hole 21, and the limiting column plays a blocking role on the vertical slider 3. The setting of the compression spring 22 can quickly realize the separation of the limiting column 19 and the vertical slider 3, and ensure that the limiting column 19 can accurately extend into and out of the vertical slider 3.

[0034] The mounting sleeve 18 is also provided with a screw plug 23 that abuts against the compression spring 22, and the limiting column 19 is provided with a step 24 that abuts against the compression spring 22. The setting of the screw plug 23 and the step 24 facilitates the abutment of the compression spring 22, ensures the smoothness of the contraction of the compression spring 22, and ensures the straightness of the movement of the limiting column 19. The limiting column 19 is also provided with an adjusting nut 25 for adjusting the movement stroke of the limiting column 19. Specifically, the limiting column 19 is provided with an external thread, and the adjusting nut 25 is arranged on the external thread. The movement stroke of the limiting column 19 is adjusted by adjusting the position of the nut 25 on the limiting column 19, thereby adjusting the depth of the limiting column 19 in the vertical slider 3. The limit column 19 is provided with a hemispherical limit head 26 extending into the vertical slider 3, and the hemispherical limit head 26 and the limit column 19 are an integrated structure. The hemispherical limit head 26 can quickly extend into the upper limit hole 20 and the lower limit hole 21 of the vertical slider 3, which is also convenient for the limit column 19 to quickly detach from the vertical slider 3. The hemispherical limit head 26 and the limit column 19 are set as an integrated structure, which simplifies the installation process between the hemispherical limit head 26 and the limit column 19, improves the connection strength between the hemispherical limit head 26 and the limit column 19, and simplifies the processing technology.

[0035] like Figure 3 As shown, the hydraulic cylinder 153 acts downward, the upper connecting rod 10, the lower connecting rod 11 and the vertical slide block 3 slide downward, and when the lower limit hole 21 of the vertical slide block 3 slides to the position of the limit column 19, the limit column 19 is pushed into the lower limit hole 21 under the action of the compression spring 22. At this time, the vertical slide block 3 is restricted from sliding downward, and the hydraulic cylinder 15 continues to act downward, and the upper connecting rod 10 and the lower connecting rod 11 rotate along the rotation point, as shown in FIG. Figure 5 As shown, when the lower connecting rod 11 is opened to the maximum angle, the hydraulic cylinder 15 continues to act downward, and the vertical slider 3, the upper connecting rod 10, and the lower connecting rod 11 slide downward at the same time, pushing the limit column 19 open, as shown in FIG. Figure 6 As shown, when the upper limit hole 20 of the vertical slider 3 slides to the position of the limit column 19, the limit column 19 is pushed into the upper limit hole 20 under the action of the compression spring 22, and the vertical slider 3 is restricted from sliding. Figure 7 As shown, the hydraulic cylinder 15 acts upward, the upper connecting rod 10 and the lower connecting rod 11 rotate along the rotation point, and when the angle of the lower connecting rod 11 is closed to the minimum, the roller 6 clamps the packaging film 27. At this time, the hydraulic cylinder 15 continues to act upward, and the vertical slider 3, the upper connecting rod 10, and the lower connecting rod 11 slide upward at the same time, pushing the limit column 19 open, as shown in FIG. Figure 8 As shown, the packaging film 27 is placed at a predetermined storage position, and a certain number of packaging films 27 can be clamped to the storage position by repeating the above-mentioned actions.
