[0001] The utility model relates to the technical field of cotton pad production, in particular to a cotton pad cutting device. Background Art
[0002] Cotton pads generally consist of at least two layers of cotton layers. Currently, the cutting machines for cutting raw material tapes generally use a single cutting knife for cutting. As a result, when cutting cotton pads, the cut positions of the cotton pads are glued together, resulting in the product quality not meeting the production requirements. Especially when producing special-shaped cotton pads, this situation occurs frequently. Summary of the Utility Model
[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a cotton pad cutting device, which can improve the cutting quality of cotton pads, reduce the rejection rate, and save costs.

The upper cutting device includes a lifting mechanism and an upper cutting knife arranged on the lifting mechanism. The lifting mechanism drives the upper cutting knife to move away from or close to the lower cutting knife. The lower cutting knife is provided with a wavy first cutting edge, and the upper cutting knife is provided with a second cutting edge matching the first cutting edge.
[0005] The cotton pad cutting device according to an embodiment of the utility model has at least the following beneficial effects: both the upper cutting knife and the lower cutting knife are provided with wavy cutting edges, and as shown in the figure, the first cutting edge matches the second cutting edge, which can realize the cutting of special-shaped cotton pads. Further, when the raw material tape is conveyed to the cutting device, after the end of the raw material tape is conveyed to the cutting position, the lifting mechanism drives the upper cutting knife to descend and cooperate with the lower cutting knife to jointly cut the raw material tape. Among them, when cutting the raw material tape, the supporting part of the raw material tape by the cutting table and the cutting position of the raw material tape by the lower cutting knife can generate an upward force on the cut position of the raw material tape, while the upper cutting knife generates a downward force on the cut position of the raw material tape.

[0029] Referring to Figures 1 to 3 , an embodiment of the present utility model provides a cutting device for cotton pads 400, which includes a feeding device, a cutting device 100, and a discharging device 200 arranged in sequence along the conveying direction of the raw material belt; the cutting device 100 includes a cutting table 110, a lower cutting knife 111 arranged on the cutting table 110, and an upper cutting device. The upper cutting device includes a lifting mechanism and an upper cutting knife 121 arranged on the lifting mechanism. The lifting mechanism drives the upper cutting knife 121 to move away from or close to the lower cutting knife 111. The lower cutting knife 111 is provided with a wavy first cutting edge, and the upper cutting knife 121 is provided with a second cutting edge matching the first cutting edge.
[0030] Both the upper cutting knife 121 and the lower cutting knife 111 are provided with wavy cutting edges. And as shown in the figure, the first cutting edge matches the second cutting edge, so that the cutting of special-shaped cotton pads 400 can be realized. Further, when the raw material belt is conveyed to the cutting device 100, after the end of the raw material belt is conveyed to the cutting position, the lifting mechanism drives the upper cutting knife 121 to descend and cooperate with the lower cutting knife 111 to jointly cut the raw material belt. Among them, when cutting the raw material belt, the supporting part of the raw material belt by the cutting table 110 and the cutting position of the raw material belt by the lower cutting knife 111 can generate an upward force on the cut position of the raw material belt, while the upper cutting knife 121 generates a downward force on the cut position of the raw material belt. The two forces in opposite directions can prevent the cut position of the raw material belt from sticking, ensuring the product quality of the cotton pads 400, reducing raw material loss, and helping to reduce production costs.
[0031] According to some embodiments of the present application, the upper cutting device further includes a support seat 120. The support seat 120 is connected to the output end of the lifting mechanism, and the upper cutting knife 121 is detachably installed on the support seat 120. Specifically, as shown in the figure, the lifting mechanism includes a first motor 130 and a cam mechanism 140. One end of the cam mechanism 140 is connected to the output end of the first motor 130, and the other end is connected to the support seat 120.
[0032] Further, a guiding column 112 is arranged on the cutting table 110. One end of the guiding column 112 is inserted into the guiding insertion hole on the support seat 120. Among them, the guiding column 112 guides the lifting of the support seat 120 to ensure the cutting quality of the product. Further, a buffer spring 113 is sleeved outside the guiding column 112. One end of the buffer spring 113 abuts against the cutting table 110, and the other end abuts against the support seat 120.
[0033] According to some embodiments of the present application, the slitting table 110 is provided with a blanking opening 114, and the feeding port of the blanking device 200 is connected to the blanking opening 114. Specifically, as shown in the figure, the blanking device 200 includes a conveying pipe 210 and a swing cylinder 220. The feeding port of the conveying pipe 210 is connected to the blanking opening 114, and the output end of the swing cylinder 220 is connected to the outer wall of the conveying pipe 210. The swing cylinder 220 drives the conveying pipe 210 to reciprocate in the horizontal direction. When the slitting device 100 has slit a preset number of finished cotton pads 400, the swing cylinder 220 drives the conveying pipe 210 to move, so that the finished cotton pads 400 are automatically divided into stacks according to the preset quantity, facilitating the workers to pick up and pack the materials.
[0034] Specifically, as shown in the figure, the blanking opening 114 is arranged below the upper cutting knife 121. When a single cutting is performed, while the upper cutting knife 121 descends for cutting, it also pushes the completed cotton pad 400 downward, pushing the cotton pad 400 into the blanking opening 114, thereby realizing the automatic conveying of the cotton pad 400 into the conveying pipe 210 and achieving the automatic blanking of the cotton pad 400. The structure is simple and practical.
[0035] Further, to ensure that the cotton pad 400 can smoothly enter the blanking opening 114, a pushing block 122 is also arranged on the support base 120. The pushing block 122 is used to increase the contact area between the upper cutting knife 121 and the cotton pad 400, so that the cotton pad 400 can smoothly enter the blanking opening 114 and will not be folded when being pushed due to too small a contact area.
[0036] Specifically, as shown in the figure, the blanking opening 114 is in a funnel structure to facilitate the cotton pad 400 to enter the conveying pipe 210.
[0037] According to some embodiments of the present application, a folding mechanism 300 is arranged between the feeding device and the slitting device 100. The folding mechanism 300 includes a mounting bracket 310 and a triangular guide plate 320 mounted on the mounting bracket 310. A guide ridge 321 is formed by the middle convex of the triangular guide plate 320. When the raw material belt passes through the triangular guide plate 320, the raw material belt can be automatically folded. Among them, the guide ridge 321 on the triangular guide plate 320 plays a guiding role in the folding of the raw material belt. Further, a first bracket 330 is arranged on the mounting bracket 310, and the triangular guide plate 320 is mounted on the first bracket 330. The triangular guide plate 320 is rotatably connected to the first bracket 330. Workers can adjust the position of the triangular guide plate 320 according to the actual situation. Further, a second bracket 340 is arranged on the mounting bracket 310, and a clamping mechanism composed of two clamping rollers 341 is arranged on the second bracket 340. A gap for the raw material belt that has completed folding to pass through is left between the two clamping rollers 341.
