[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] The sterilizing cotton pad cutting device is used to cut the cotton pad; Figure 1 As shown, it includes a cutting frame 1, a cutting lifting plate 2, a cutting cylinder 3, an upper knife seat 4, a lower knife seat 5 and a blade 6;

[0033] The cutting frame 1 is provided with two guide posts 11, and the cutting lifting plate 2 is sleeved on the two guide posts 11, and can move up and down relative to the guide posts 11;

[0034] The cutting cylinder 3 is installed on the top of the cutting frame 1, and the output end of the cutting cylinder 3 is connected to the upper surface of the cutting lifting plate 2 to drive the cutting lifting plate 2 to move up and down;

[0035] The upper knife seat 4 is connected to the lower surface of the cutting lifting plate 2 through a connecting rod; the blade 6 is fixedly mounted on the upper knife seat 4; and the lower knife seat 5 is mounted on the bottom of the cutting frame 1.

[0036] The upper knife seat 4 is provided with a pre-pressing assembly 7 for completing the pressing operation before cutting the cotton piece.

[0037] Preferably, a blade 6 is provided on the bottom surface of the upper knife seat 4 to divide the bottom surface of the upper knife seat 4 into two upper working surfaces 41;

[0038] The top surface of the lower knife seat 5 is provided with a knife groove 52 corresponding to the blade 6, and the knife groove 52 divides the top surface of the lower knife seat 5 into two lower working surfaces 51; the blade 6 can enter the knife groove 52, and the blade 6 entering the knife groove 52 can ensure that the cutting is in place.

[0039] Preferably, each of the two upper working surfaces 41 is provided with a pre-pressing assembly 7, such as Figure 2 As shown, the pre-pressing assembly 7 includes a pre-pressing plate 71, a pre-pressing column 72 and a spring 73; the upper working surface 41 is provided with a matching groove 42, and the pre-pressing plate 71 is installed in the matching groove 42 through the pre-pressing column 72;

[0040] A limiting structure is provided at the top of the pre-stress column 72, which forms a limit with the inside of the matching groove 42, and the pre-stress column 72 can move up and down in the matching groove 42; a spring 73 is provided between the pre-stress plate 71 and the upper working surface 41, which can realize the displacement and resetting of the pre-stress plate 71.

[0041] Preferably, the bottom surface of the pre-pressing plate 71 is lower than the plane where the tip of the blade 6 is located. This is the key point of the present design. The pre-pressing plates 71 on both sides are first contacted and pressed against the cotton sheet, and then the blade 6 falls down to complete the cutting. The action is continuous and efficient.

[0042] Preferably, the pre-pressing plate 71 corresponds to the upper working surface 41, the lower surface of the pre-pressing plate 71 is provided with a pattern, and the upper working surface 41 is also provided with a pattern, and the patterns at the two locations are opposite to each other, so that when the cotton sheet is pressed tightly, it can prevent the cotton sheet from sliding, thereby improving the success rate of cutting.

[0043] Preferably, the number of the pre-compression columns 72 is at least 3 and they are evenly distributed to ensure the stability of the upper and lower positions of the pre-compression plate 71 .

[0044] Preferably, a fixing rod 61 is respectively provided at both ends of the blade 6, and the blade 6 is connected to the cutting lifting plate 2 through the fixing rod 61. The blade 6 is fixed to the upper blade seat 4, and the two sides are fixed to the cutting lifting plate 2 through the fixing rod 61. The two-stage fixation provides stability for the blade 6 and further improves the success rate of cutting.

[0045] During operation, when the cotton sheet is conveyed to the lower knife seat 5 by the conveying device, the cutting cylinder 3 controls the cutting lifting plate 2 to fall. Since the bottom surface of the pre-pressing plate 71 is lower than the plane where the tip of the blade 6 is located, the pre-pressing plate 71 first contacts the cotton sheet when falling, and the cotton sheet is pressed by the cooperation between the pre-pressing plate 71 and the lower working surface 51 of the lower knife seat 5. At this time, under the action of the pre-pressing column 72 and the spring 73, the blade 6 will continue to fall while the cotton sheet is pressed, and the blade 6 enters the knife groove 52, thereby realizing the cutting operation of the cotton sheet.

[0046] After the cutting is completed, the cutting cylinder 3 controls the cutting lifting plate 2 to lift up, and then the next section of cotton sheet enters the workstation, and the above steps are repeated to complete the cutting of the cotton sheet.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
