[0001] The utility model relates to the technical field of fiberglass mesh tape processing, in particular to a slitting device for fiberglass mesh tape. Background Art

[0002] The fiberglass mesh tape contains high-temperature resistant and flame-retardant fibers and has the high-temperature resistant and flame-retardant properties of the high-temperature resistant and flame-retardant fibers. It is often used in places such as offices, clean rooms, manufacturing pages, packaging boxes, etc. After the fiberglass mesh tape is processed, it often needs to be slit by a slitting device.

[0003] The existing patent (Publication No.: CN213230867U) discloses a slitting device for processing high-temperature resistant and flame-retardant fiber fiberglass mesh tape, which is convenient for limiting, dust-proofing and pressing the tape, avoiding the tape from shifting and having bubbles during winding, making the quality of tape slitting and winding good, and being convenient for adjusting the distance between and replacing the slitting blades. In the process of implementing this solution, the following problems are found in the existing technology and have not been well solved:

[0004] During the use of this device, the cutting work is completed by multiple cutting blades. However, during the cutting process, the adhesive on the surface of the tape will stay on both sides of the cutting blades, which is likely to affect the subsequent cutting work during continuous cutting, and even cause inability to cut in serious cases. And it is very difficult to achieve a good sealing effect by moving the winding rod. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following further elaborates on the present utility model in conjunction with the attached Figures 1-4 drawings for a more detailed description.

[0029] Please refer to the drawings in the specification Figures 1-4, an embodiment provided by the present utility model: a grid tape slitting device, including a device main body 1 and an extension block 11. A wire reel 2 is arranged on the left side of the device main body 1, and a piston rod 5 is arranged at the center of the device main body 1. The piston rod 5 drives the movable block 4 to lift and lower to realize the cutting work. A movable block 4 is connected below the piston rod 5, and a sliding block 8 is connected to the center of the movable block 4. The sliding block 8 cooperates with the connecting block 7 to drive the linkage block 9 to move, which facilitates the disassembly of the linkage block 9. A connecting block 7 is connected to the center of the sliding block 8, a linkage block 9 is connected below the connecting block 7, and a cleaning block 10 is connected below the linkage block 9. The cutting knife 6 is cleaned by the cleaning block 10 to prevent glue adhesion, and a cutting knife 6 is arranged at the center of the cleaning block 10;

[0030] A first spring 12 is connected below the extension block 11, and a first pressing block 13 is connected below the first spring 12. The tape is driven by the first pressing block 13 to fit the take-up reel 3 to ensure the tightness of the tape. A take-up reel 3 is arranged below the first pressing block 13. A side plate 14 is connected to the left side of the extension block 11, a second spring 15 is connected below the side plate 14, and a second pressing block 16 is connected below the second spring 15. The other side of the tape is pressed by the second pressing block 16 to make the tape close to the lower part. An auxiliary rod 18 is connected above the second pressing block 16, and a storage block 17 is connected above the auxiliary rod 18.

[0031] Refer to the accompanying drawings of the specification Figures 1-4 , limiting rods are symmetrically distributed on both sides of the movable block 4. The movable block 4 and the piston rod 5 are of an integrated lifting structure, and the movable block 4 and the cutting knife 6 are of an integrated lifting structure. A cylinder is connected above the piston rod 5, and the tape is cut by the cutting knife 6, thus facilitating subsequent use.

[0032] Refer to the accompanying drawings of the specification Figures 1-4 , the connection mode between the connecting block 7 and the sliding block 8 is hot melt connection, the connection mode between the sliding block 8 and the movable block 4 is sliding connection, and the connecting block 7 and the linkage block 9 are integrally installed. The sliding block 8 drives the connecting block 7 to move, thus facilitating the disassembly of the linkage block 9 for replacing the cleaning block 10.

[0033] Refer to the accompanying drawings of the specification Figures 1-4 , cleaning blocks 10 are evenly and equidistantly distributed below the linkage block 9. Two cleaning blocks 10 are in a group, and the number of groups is the same as the number of cutting knives 6. The cleaning blocks 10 are attached to both sides of the cutting knife 6, and the surface of the cutting knife 6 is scraped by the cleaning blocks 10 to prevent a large amount of tape from adhering.

[0034] Refer to the accompanying drawings of the specification Figures 1-4The extension block 11 forms a spring return structure through the first spring 12 and the first extrusion block 13. The center line of the first extrusion block 13 coincides with the center line of the take-up wheel 3. The length of the first extrusion block 13 is consistent with the length of the take-up wheel 3. The first extrusion block 13 cooperates with the first spring 12 to ensure that the tape is always attached to the top of the take-up wheel 3.

[0035] See the attached drawings in the specification Figures 1-4 The side panel 14 is connected to the extension block 11 by hot melt connection. The side panel 14 forms a spring shock-absorbing structure with the second extrusion block 16 through the second spring 15. The second extrusion block 16 forms a sliding connection structure with the storage block 17 through the auxiliary rod 18. The second spring 15 cooperates with the second extrusion block 16 to keep the tape and the first extrusion block 13 in a tight state, thereby improving the sealing effect.

[0036] Working principle: When in use, first, the pay-off wheel 2 pays out the tape, and the tape passes through the limiting rod and the cutting knife 6 in turn and is wound above the take-up wheel 3. During use, the cutting knife 6 cuts the tape, making the tape into rolls of different widths. At the same time, the cutting knife 6 constantly rubs against the cleaning block 10 above during the cutting process, thereby cleaning the glue on both sides thereof. When the inner wall of the cleaning block 10 is stained with glue after long-term use, open the opening and closing door on one side of the device body 1, pull up the connecting block 7, so that the cleaning block 10 moves upward and out of the area of the cutting knife 6, and then pull the connecting block 7, so that the cleaning block 10 slides out of the device body 1. After replacing the new cleaning block 10, the cleaning block 10 stained with glue is cleaned and waits for the next work.

[0037] As mentioned above, during the tape winding process, it first contacts the second squeezing block 16. Due to the presence of the second spring 15, the second squeezing block 16 squeezes the tape, so that the tape moves downward. At this time, when the take-up wheel 3 wants to rewind the tape, it needs to continuously pull the tape, so that the tape between the second squeezing block 16 and the take-up wheel 3 is always in a taut state. When the take-up wheel 3 rewinds the tape, the first squeezing block 13 is limited by the first spring 12 and is always in contact with the surface of the take-up wheel 3, performing a secondary squeezing on the tape to ensure the sealing of the tape rewinding.

[0038] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
