[0014] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 3 It can be seen that a sanitary pad packet sealing and cutting device includes a frame 1, a conveyor belt 2 is provided on the frame 1, a clamping mechanism and a sealing and cutting mechanism are sequentially provided on the frame 1, the clamping mechanism includes a left clamping plate 3 and a right clamping plate 4 telescopically arranged on both sides of the frame 1, the sealing and cutting mechanism includes a positioning plate 5 and a sealing and cutting plate 6 telescopically arranged on both sides of the frame 1, a first hot pressing plate 7 is provided at both ends of the positioning plate 5, a second hot pressing plate 8 corresponding to the first hot pressing plate 7 is provided at both ends of the sealing and cutting plate 6, a cutting edge 9 is provided in the middle of the positioning plate 5, a cutting knife 10 corresponding to the cutting edge 9 is telescopically provided in the middle of the sealing and cutting plate 6, the first hot pressing plate 7 and the second hot pressing plate 8 cooperate to complete the edge sealing of the sanitary pad packet, and the cutting knife 10 cooperates with the cutting edge 9 to complete the slitting of the sanitary pad packet.

[0016] When the utility model is used in a specific way,

[0017] The sanitary pad wrapped in the packaging bag is placed on the conveyor belt 2 and transported forward. When it reaches the position of the clamping mechanism, the left clamping plate 3 and the right clamping plate 4 clamp the small package, and then the sealing and cutting mechanism closes to the middle, the positioning plate 5 and the sealing and cutting plate 6 clamp the middle part of the adjacent small packages, the first hot pressing plate 7 and the second hot pressing plate 8 perform heat sealing, so that the adjacent small packages are sealed at the same time, and then the cutter 10 cooperates with the cutting edge 9 to cut the adjacent small packages to complete the sealing and cutting of the sanitary pad small package, and then the clamping mechanism and the sealing and cutting mechanism release the sanitary pad small package, and the conveyor belt 2 continues to feed forward. When it reaches the next operating position, the above operations are repeated to realize the sealing and cutting processing of the sanitary pad small package in sequence.

[0018] A motor 11 for driving the conveyor belt 2 is arranged on the side of the frame 1. The motor 11 is controlled by a controller and is unified with the sealing and cutting action, thereby reducing energy waste, ensuring action consistency, improving production efficiency, and ensuring processing effect.

[0019] A baffle 12 is provided at the end of the right clamping plate 4, and the baffle 12 exceeds the edge of the left clamping plate 3. The left clamping plate 3 and the right clamping plate 4 are driven by the first hydraulic cylinder 13 to form a structure in which the left clamping plate 3 and the right clamping plate 4 are telescopic on both sides of the frame 1. The baffle 12 can limit the end of the sanitary pad package. When the sanitary pad package is fed forward, the right clamping plate 4 is first extended forward, and the baffle 12 blocks the sanitary pad package, and then it is clamped to limit the sanitary pad package to make its position uniform, thereby ensuring the consistency of the sealing and cutting position.

[0020] The positioning plate 5 is driven by the second hydraulic cylinder 14, and the outer side of the sealing and cutting plate 6 is connected to a fixing plate 16 via a spring 15. The fixing plate 16 is driven by the third hydraulic cylinder 17 to form a structure in which the fixing plate 16 is telescopic on the side of the frame 1, and the cutter 10 is connected to the fixing plate 16 via a connecting rod 18.

[0021] The specific steps of the sealing and cutting operation are as follows: the positioning plate 5 moves toward the middle under the action of the second hydraulic cylinder 14, and the sealing and cutting plate 6 moves inward under the action of the third hydraulic cylinder 17. Due to the action of the spring 15, the third hydraulic cylinder 17 drives the fixed plate 16 to move while the sealing and cutting plate 6 moves synchronously. When the sealing and cutting plate 6 and the positioning plate 5 are close, the first hot pressing plate 7 and the second hot pressing plate 8 are in contact, and the position of the sealing and cutting plate 6 remains stationary. At this time, the third hydraulic cylinder 17 continues to push the fixed plate 16 forward, which can drive the cutter 10 to move forward. The cutter 10 cooperates with the cutting edge 9 to complete the cutting of the sanitary pad package.

[0022] Compared with the prior art, the utility model has the following beneficial effects: a horizontal structure is adopted, so that the heat sealing structure is easy to arrange, thereby better positioning the sanitary pad package, improving processing convenience, ensuring processing consistency and stability, and thus ensuring the final quality of the product.
