DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1: Please refer to Figures 1 - 4 andFigure 6 As shown in the figure, for the existing automatic tape slitter, different models have different width requirements during tape slitting, making it inconvenient to adjust the slitting width. To solve this technical problem, the following technical content is disclosed in this embodiment;

[0027] On the upper surface of the base 1, brackets 7 are fixedly connected to both the left and right sides at the rear end. At the front side of the top of the bracket 7, a telescopic rod 8 is fixedly connected. And the output end of the telescopic rod 8 is fixedly connected with a slitting device 9. The slitting device 9 is composed of a connecting ring 901, a base plate 902, a second motor 903, a connecting rod 904, a fixing ring 905, and a cutting knife 906. The connecting ring 901 is fixedly connected to the output end of the telescopic rod 8 by bolts. And the bottom surface of the connecting ring 901 is fixedly connected with a base plate 902. And the left end of the upper surface of the base plate 902 is fixedly connected with a second motor 903. The output shaft of the second motor 903 is fixedly connected with a connecting rod 904. And the left end of the connecting rod 904 penetrates through the inner side of the connecting ring 901. And a plurality of groups of fixing rings 905 are slidably connected to the connecting rod 904. A plurality of cutting knives 906 are slidably connected to the connecting rod 904. And the cutting knives 906 are fixedly connected to the inner side of each group of fixing rings 905 by bolts. And the fixing ring 905 is an "L"-shaped circular ring piece. The outer end of the fixing ring 905 is fixedly connected to the connecting rod 904 by bolts. And the right end of the connecting rod 904 is rotatably connected to a groove opened on the left side of the stopper 10. And the four corners of the top of the stopper 10 are fixedly connected to the output end of the right telescopic rod 8 by bolts. At the front end of the inner side of the top of the bracket 7, a scale plate 11 is fixedly connected. And the scale plate 11 is installed above the slitting device 9;

[0028] The output end of the telescopic rod 8 drives the slitting device 9 and the stopper 10 to move up and down to cut the tape. Loosen the bolts on the fixing ring 905, and each group of fixing rings 905 and cutting knives 906 can be moved left and right. According to the scale plate 11 above the cutting knives 906, the distance between the cutting knives 906 is adjusted. After adjusting the distance between the cutting knives 906, tighten the bolts of the fixing ring 905, and start the second motor 903. The output shaft of the second motor 903 drives the connecting rod 904 to rotate, so that the cutting knives 906 rotate to cut the tape below;

[0029] Embodiment 2: For the existing automatic tape slitter, the adhesive on the tape has a certain stickiness, making it inconvenient to clean the cutting tool. Therefore, this embodiment adopts the following technical solutions, as shown in Figure 1 、 Figure 2 and Figure 4 shown;

[0030] At the inner rear end of the upper end of the bracket 7, a fixing plate 12 is fixedly connected. At the front side of the fixing plate 12, grinding blocks 13 are fixedly connected at equal intervals. In the middle of the front side of the grinding block 13, a groove is formed. The inner side surface of the groove formed in the middle of the front side of the grinding block 13 is in fit with the outer side surface of the rear end of the cutting knife 906. And the grinding block 13 is located at the rear side of the highest position of the cutting knife 906 during its rising process;

[0031] After the cutting knife 906 is adjusted to the same spacing as the grinding block 13, when the cutting knife 906 rises to the highest layer, the rear end of the cutting knife 906 slides into the groove formed in the middle of the front side of the grinding block 13. The cutting knife 906 continues to rotate. Since the outer side surface of the cutting knife 906 is in fit with the inner side surface of the groove formed in the middle of the front side of the grinding block 13, when the cutting knife 906 rotates, the grinding block 13 grinds the cutting knife 906 and at the same time grinds off the adhesive on the surface of the cutting knife 906, preventing the accumulation of adhesive on the surface of the cutting knife 906 and affecting the slitting of the tape;

[0032] Embodiment 3: In the existing tape automatic slitting machine, each group of tape slitting requires installation and removal from the slitting machine, which is not convenient for disassembling and assembling the tape. Therefore, this embodiment adopts the following technical solutions, as Figure 1 and Figures 3 - 5 shown;

[0033] At the front end of the upper surface of the base 1, a support device 2 is fixedly connected. The support device 2 is composed of a support column 201, a storage groove 202, a slide rail 203 and a baffle 204. On the left and right sides of the front end of the upper surface of the base 1, support columns 201 are fixedly connected. In the middle of the upper surface of the support column 201, a storage groove 202 is formed. On the front and rear sides of the upper right side of the right support column 201, slide rails 203 are fixedly connected. A baffle 204 is slidably connected inside the slide rail 203. And a long strip-shaped through groove is formed from top to bottom at the right end of the slide rail 203. A bolt is slidably connected in the through groove at the right end of the slide rail 203. The left end of the bolt in the through groove at the right end of the slide rail 203 is threadedly connected with the front and rear ends of the left side of the baffle 204. At the left top end of the left support column 201, a first motor 3 is fixedly connected. The output shaft of the first motor 3 is fixedly connected with a clamping block 4. And a square groove is formed on the right side of the clamping block 4. A rotating rod 5 is slidably connected in the square groove on the right side of the clamping block 4. The left end of the rotating rod 5 is a square rod piece. And the outer side surface of the square rod piece at the left end of the rotating rod 5 is in fit with the inner side surface of the square groove on the right side of the clamping block 4. The two ends of the rotating rod 5 are placed in the storage groove 202 formed at the upper end of the support column 201. The right side surface of the rotating rod 5 is in fit with the right side surface of the baffle 204. And a tape roll 6 is sleeved on the outer side of the rotating rod 5. The two ends of the tape roll 6 are fixed on the rotating rod 5 by bolts;

[0034] Loosen the bolts fixing the baffle 204, move the baffle 204 to the lowest end of the slide rail 203, pull the rotating rod 5 to the right, so that the left end of the rotating rod 5 disengages from the clamping block 4. After removing the rotating rod 5, sleeved the tape roll 6 on the rotating rod 5. After the sleeving is completed, insert the left end of the rotating rod 5 into the clamping block 4. Place the rotating rod 5 in the placement groove 202, move the baffle 204 upward, so that the left side of the right end of the baffle 204 is in contact with the right side of the rotating rod 5. Tighten the bolts for fixing the baffle 204 on the slide rail 203 to prevent the rotating rod 5 from disengaging from the support column 201 when rotating. After the installation is completed, adjust the distance between the cutting knives 906 and start cutting. Start the first motor 3, so that the output shaft of the first motor 3 drives the tape roll 6 to rotate and cut the tape. After the cutting is completed, lower the baffle 204, pull the rotating rod 5 to the right, and remove the tape roll 6. This operation is beneficial to the disassembly and assembly of the tape roll 6 and prevents the tape roll 6 from disengaging from the support column 201 when rotating.
