The present utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-4 As shown, the utility model provides a double-sided adhesive tape production trimming device, comprising a base 1, a front side plate 2, a support plate 3 and a rear side plate 4 are arranged on the top of the base 1, the front side plate 2, the support plate 3 and the rear side plate 4 are arranged in two groups opposite to each other, the front side plate 2, the support plate 3 and the rear side plate 4 are arranged in sequence from left to right, a pressure-feeding component 5 is arranged between the two groups of front side plates 2 and the rear side plates 4, which can flatten and transport the double-sided adhesive tape, and a support plate 6 and a slide are arranged on the side wall of the front side plate 2 facing the support. Rail 7, slide rail 7 is located directly below the support plate 6, a moving block 8 is slidably connected to the slide rail 7, a tension spring 9 is connected to the top of the moving block 8, the top of the tension spring 9 is connected to the support plate 6, a stretching roller 10 is rotatably connected between the two groups of moving blocks 8, the height of the bottom of the cutter 13 from the base 1 is greater than the height of the bottom of the stretching roller 10 from the base 1, the double-sided adhesive tape of the pressure-feeding component 5 passes under the stretching roller 10, and the transported double-sided adhesive tape is flattened under the dead weight of the stretching roller 10 to prevent it from loosening.

[0022] like Figure 1-3As shown, a guide rail 11 is connected between the two groups of support plates 3, a sleeve 12 is slidably sleeved on the guide rail 11, a cutter 13 is arranged at the bottom of the sleeve 12, and electric push rods 14 are installed on the outer side walls of the two groups of support plates 3. The output ends of the two groups of electric push rods 14 respectively penetrate the support plates 3 and are connected to the two groups of sleeves 12. The electric push rod 14 controls the sleeve 12 to slide on the guide rod through its own telescopic control to adjust the position of the cutter 13 under the sleeve 12, which is suitable for edge cutting of double-sided tapes of different widths.

[0023] like Figure 1-4 As shown, the pressing and conveying assembly 5 includes a lower pressing roller 15 and an upper pressing roller 16. The lower pressing roller 15 is rotatably installed between the two groups of front side plates 2 and the rear side plates 4. The front side plates 2 and the rear side plates 4 are both provided with a slide groove 17. A slider 18 is slidably arranged in the slide groove 17.
