Description

Technical Field

[0001] The present invention belongs to the technical field of wet wipe processing equipment, and particularly relates to a structure for adjusting the length of arbitrarily folded cloth. Background Art

[0002] In the existing cloth production equipment of a roller, the cloth feeding knife and the bottom cloth cutting knife are designed on one roller. When adjusting the length of the produced cloth in the cloth production equipment of the roller, since the position of the bottom cloth cutting knife relative to the cloth feeding knife cannot be moved and adjusted, only the cutting position of the upper cloth cutting knife on the bottom cloth cutting knife in the cloth production equipment of the roller can be adjusted. Therefore, when adjusting the cloth length, it is necessary to loosen the gear of the upper cloth cutting knife roller, and then continuously adjust the position of the gear of the upper cloth cutting knife roller to achieve the cloth length to be cut. However, the position of the gear of the upper cloth cutting knife roller is difficult to be adjusted in place at one time and needs to be adjusted multiple times, resulting in extremely inconvenient adjustment of the cloth length, consuming a large amount of time, and seriously affecting the production efficiency of the cloth production equipment of the roller.

[0003] In addition, the adjusted cloth length depends on the width of the bottom cloth cutting knife. Since the width of the bottom cloth cutting knife is limited, the adjustment range of the cloth length is limited. When non-standard products need to be produced, it is necessary to redesign the upper cloth cutting knife roller, which not only greatly extends the production cycle of non-standard products, but also increases a large amount of expenses and the consumption of resources. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a structure for adjusting the length of arbitrarily folded cloth, which can effectively reduce the time for adjusting the length of the folded cloth, and effectively reduce the workload and difficulty of adjusting the length of the folded cloth.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following further elaborates on the present invention through specific embodiments, but does not limit the scope of the present invention.

[0028] Example 1:

[0029] A structure for adjusting any folded cloth length, the structure of which is as Figure 1-7As shown in the figure, it includes a lower cloth cutting knife roller 2 arranged on a drum cloth production device, an upper cloth cutting knife roller 1 cooperating with the lower cloth cutting knife roller 2, a cloth plugging knife roller 3 cooperating with the lower cloth cutting knife roller 2 arranged on one side of the lower cloth cutting knife roller 2, and a cloth clamping and folding roller 4 cooperating with the cloth plugging knife roller 3 arranged under the cloth plugging knife roller 3; an adjustment link gear system 11 cooperating with the cloth plugging knife roller 3 and the lower cloth cutting knife roller 2 is arranged on the cloth plugging knife roller 3.

[0030] The adjustment link gear system 11 includes an idler gear I 12 and an idler gear II 13 that mesh with each other. A transition bearing rotatably connected to the idler gear I 12 is arranged on the rotating shaft of the idler gear I 12, and an adjustment screw rod 6 connected to the transition bearing is arranged on the transition bearing. An adjustment motor 5 cooperating with the adjustment screw rod 6 is arranged on the drum cloth production device, and a motor fixing block connected to the drum cloth production device is arranged on the adjustment motor 5.

[0031] A cloth plugging knife roller gear 15 is arranged on one side of the cloth plugging knife roller 3, a cloth plugging knife roller adjustment gear 16 is arranged on the side of the cloth plugging knife roller gear 15 away from the cloth plugging knife roller 3, and the cloth plugging knife roller adjustment gear 16 meshes with the idler gear I 12.

[0032] A lower cloth cutting knife roller gear 18 is arranged on the side of the lower cloth cutting knife roller 2 close to the cloth plugging knife roller gear 15, a lower cloth cutting knife roller adjustment gear 17 is arranged on the side of the lower cloth cutting knife roller gear 18 away from the lower cloth cutting knife roller 2, and the lower cloth cutting knife roller adjustment gear 17 meshes with the idler gear II 13. A cloth clamping and folding roller gear 20 is arranged on the cloth clamping and folding roller 4, and the cloth clamping and folding roller gear 20 meshes with the cloth plugging knife roller gear 15. The lower cloth cutting knife roller gear 18 meshes with an upper cloth cutting knife roller gear 14 arranged on the upper cloth cutting knife roller.

[0033] A cloth plugging knife cam disc 19 is arranged on the cloth plugging knife roller 3, a cloth plugging knife 9 is arranged on the cloth plugging knife cam disc 19, and the cloth plugging knife 9 cooperates with a cloth clamping knife arranged on the cloth clamping and folding wheel. A cloth cutting bottom knife 8 is arranged on the lower cloth cutting knife roller 2, and the cloth cutting bottom knife 8 cooperates with a cloth cutting knife 7 arranged on the upper cloth cutting roller. The adjustment link gear system 11 further includes an adjustment link I 21 rotatably connected to the rotating shafts of the idler gear I 12 and the cloth plugging knife roller 3, an adjustment link II 22 rotatably connected to the rotating shafts of the idler gear II 13 and the lower cloth cutting knife roller 2, and an auxiliary adjustment link 23 rotatably connected to the end of the rotating shaft of the idler gear II 13 at the end of the rotating shaft of the idler gear I 12.

[0034] During use, the cloth clamping and folding roller 4 drives the cloth plugging knife roller gear 15 through the cloth clamping and folding roller gear 20, thereby driving the cloth plugging knife roller 3 to rotate. The cloth plugging knife roller 3 drives the idler gear I 12 and the idler gear II 13 to rotate through the cloth plugging knife roller adjustment gear 16, and then drives the lower cloth cutting knife roller adjustment gear 17 to rotate through the idler gear II 13, thereby driving the lower cloth cutting knife roller 2 to rotate. The lower cloth cutting knife roller 2 drives the upper cloth cutting knife roller gear 14 to rotate through the lower cloth cutting knife roller gear 18, thereby driving the upper cloth cutting knife roller 1 to rotate.

[0035] When it is necessary to adjust the length of the folded cloth, the adjusting motor 5 fixed on the drum cloth production equipment by the motor fixing block rotates, driving the adjusting lead screw 6 to extend and retract, thereby driving the deformation of the adjusting link gear system 11. The specific steps are as follows: The adjusting lead screw 6 drives the idler wheel I 12 to move. Under the interaction among the adjusting link I 21, the adjusting link II 22, and the auxiliary adjusting link 23, the idler wheel II 13, the adjusting gear 16 of the cloth feeding knife roller, and the adjusting gear 17 of the lower cloth cutting knife roller move accordingly. The relative rotational positions of the adjusting gear 16 of the cloth feeding knife roller and the adjusting gear 17 of the lower cloth cutting knife roller change, thereby adjusting the positions of the cloth feeding knife roller 3 and the lower cloth cutting knife roller 2. The center of the bottom cloth cutting knife 8 and the position of the cloth feeding knife 9 change accordingly, thereby changing the length of the folded cloth. Figure 1 and Figure 2 respectively represent two cloth length dimensions after adjusting the positions. Figure 1 is 87 mm. Figure 2 is 113 mm.

[0036] When the cloth feeding knife cam disc 19 moves with the cloth feeding knife roller 3, the cloth feeding knife 9 is in a retracted state when approaching the lower cloth cutting knife roller 2 and in an extended state when approaching the cloth clamping and folding roller 4, so as to ensure that the cloth feeding knife 9 can stuff the cloth into the cloth clamping and folding roller 4 while avoiding interference between the cloth feeding knife 9 and the lower cloth cutting knife roller 2.
