[0002] The full name of polarizer is polarizing film. The imaging of liquid crystal display must rely on polarized light. Liquid crystal has two polarizing films in front and behind that are closely attached to the liquid crystal glass, forming a liquid crystal film with a total thickness of about 1mm. In the process of producing polarizers, the sheets need to be cut.

[0003] Although the existing circular polarizer production equipment and preparation process can meet the basic needs of cutting and processing the sheets, waste is usually generated in the process of cutting and processing the sheets. In the prior art, the generated waste is usually retained on the processing table, and the device often cannot automatically clean up the generated waste. After completing a cutting process, workers need to manually clean up the waste on the processing table before continuing to load the sheets and perform subsequent cutting processes. That is, between every two cutting processes, workers need to spend a lot of time to clean up the waste generated by cutting, which will affect the overall efficiency of the sheet cutting process, and therefore cannot fully meet people's usage needs.

A second telescopic push rod 111 is vertically arranged at the bottom of the fixing frame 110, and a receiving groove 112 that can pass through the through hole 109 and is sleeved on the outside of the cutting groove 108 is detachably arranged on the output shaft of the second telescopic push rod 111, and a receiving groove 112 that can pass through the through hole 109 and is sleeved on the outside of the cutting groove 108 is detachably arranged, a blowing chamber is arranged inside the left side wall of the cutting groove 108, a blowing hole 113 connected with the blowing chamber is arranged on the inner wall of the left end of the cutting groove 108, and an air inlet pipe 114 connected with the blowing chamber is arranged on the outer wall of the cutting groove 108.

[0035] like Figure 1 , 2 As shown in , 4, the cutting module includes a third telescopic push rod 201 vertically arranged on the top of the mounting frame 103, and the lower end of the output shaft of the third telescopic push rod 201 is provided with a fixing groove 202 with a lower end opening, and a cutting knife 203 is clamped in the fixing groove 202, and a fixing bolt 204 for fixing the cutting knife 203 is screwed on the fixing groove 202, and the cutting knife 203 is provided with a threaded fixing hole screwed and fixed with the fixing bolt 204.

[0036] The worker can first place the sheet to be cut into the placement slot 105, and then drive the output shaft of the first telescopic push rod 107 to extend a certain length, so that the inner wall of the left end of the cutting slot 108 contacts the left end of the sheet, thereby fixing the sheet by the cooperation of the left side wall of the cutting slot 108 and the right side wall of the placement slot 105.

[0037] Then, the output shaft of the first telescopic push rod 107 is synchronously driven to shorten a certain length to the left, and the slide seat of the linear slide 104 is driven to move to the left, thereby synchronously driving the placement groove 105, the cutting groove 108 and the sheet to move to the left to the bottom of the mounting frame 103, and making the cutting position of the sheet located below the cutting knife 203.

[0038] Afterwards, the worker drives the output shaft of the third telescopic push rod 201 to extend downward by a certain length and shorten upward by a certain length, thereby driving the cutting knife 203 to move downward first to cut the sheet, and then reset upward, so that the finished sheet is located in the placement groove 105 and the waste is located in the cutting groove 108.

[0039] Afterwards, the output shaft of the first telescopic push rod 107 is shortened by a certain length, driving the cutting groove 108 and the waste to the upper position of the through hole 109, and then the output shaft of the second telescopic push rod 111 is extended by a certain length, driving the receiving groove 112 to be sleeved on the outside of the cutting groove 108, and then wind is blown into the blowing chamber through the air inlet pipe 114, and the wind will be blown out to the right from the multiple blowing holes 113, thereby blowing the waste in the cutting groove 108 into the receiving groove 112, and then the air supply to the air inlet pipe 114 is stopped, and the receiving groove 112 is driven to reset by the second telescopic push rod 111, thereby automatically completing the cleaning of the waste.

[0040] Afterwards, the placement groove 105 and the finished sheet can be driven to return to the right by the linear slide 104, and then the worker can take the finished sheet out of the placement groove 105, thereby completing a cutting process of the sheet.

[0041] Most of the finished sheet falls in the placement groove 105, and a small part is suspended on the left side of the placement groove 105, so when the placement groove 105 is moved and adjusted by the linear slide 104, the finished sheet will not easily fall from the placement groove 105; because the waste material falls in the cutting groove 108, when the cutting groove 108 is driven to move by the first telescopic push rod 107, the waste material can be easily driven to move along with the cutting groove 108.

[0042] When the placement groove 105 and the cutting groove 108 are driven by the first telescopic push rod 107 and the linear slide 104 to move toward the bottom of the mounting frame 103, both sides of the sheet will be clamped and fixed by the placement groove 105 and the cutting groove 108, so the sheet can be effectively prevented from being offset.

The output shaft of the second telescopic push rod 111 can be flexibly fixed to the receiving groove 112 by clamping and fixing the output shaft of the second telescopic push rod 111 with the fastening cylinder 307, and then passing the fastening bolt 308 through the side wall of the fastening cylinder 307 and screwing and fixing it with the threaded fastening hole.

[0049] The fastening cylinder 307 , the receiving groove 112 and the output shaft of the second telescopic push rod 111 can be separated by simply separating the fastening bolt 308 from the threaded fastening hole, so that the receiving groove 112 can be removed and the waste in the receiving groove 112 can be cleaned.

[0050] According to another embodiment of the present invention, Figure 1 , 2 As shown, the side end of the mounting plate 115 is also provided with a connecting plug plate 309 that is horizontally penetrated and slidably connected to the vertical plate 106, and the vertical plate 106 is provided with a connecting socket 310 that is slidably connected to the connecting plug plate 309.
