Description

Technical Field

[0001] The utility model relates to the technical field of foam tapes, and specifically relates to a die-cutting mechanism for the production of foam tapes. Background Art

[0002] The foam tape is made by using an advanced fully automatic continuous coating line, selecting foams such as PE, EVA, XPE, ethylene propylene diene monomer, rubber and plastic, needle punched felt, and hot melt felt as the base materials, respectively coating various high-quality adhesives and matching with various high-quality auxiliary materials, and compounding them by a special process to form a soft, heat-insulating, heat-preserving, and sealing adhesive tape. A die-cutting mechanism is required during the production process of the foam tape.

[0003] In the prior art, a Chinese patent with the publication number of CN220128877U discloses a die-cutting mechanism for the production of foam tapes. The die-cutting mechanism for the production of foam tapes includes a base, on which a top plate is slidably arranged, and a cutting knife is arranged on the top plate; a fixing plate is slidably arranged on the base, an installation plate is arranged on the fixing plate, cleaning columns are arranged at both ends of the installation plate, and the cleaning columns are in contact with the cutting knife. By sliding the fixing plate, the cleaning columns can clean the cutting knife. The top plate drives the cutting knife to cut the foam tape on the base. After cutting, the foam tape is likely to remain on the cutting knife. When cleaning the residual foam tape on the cutting knife, it is necessary to first start the motor, so that the motor drives the lead screw to rotate, thereby driving the cleaning columns on the fixing plate to clean the residues on both sides of the cutting knife. With a simple structure, the device is convenient for cleaning the residues on both sides of the cutting knife.

[0004] However, the above solution still has some deficiencies. For example, when cutting the foam tape in the above solution, the staff needs to manually press the top plate first. The top plate drives the cutting knife to cut the foam tape on the base. Over time, the staff will gradually become fatigued, and the strength of pressing the top plate will become smaller, which will slow down the cutting rate of the foam tape, thereby reducing the production efficiency of the foam tape.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: a die-cutting mechanism for the production of foam tape, including a cutting table board 1. A support frame 2 is welded on the upper surface of the cutting table board 1. A knife groove 7 is formed on the upper surface of the support frame 2. A die-cutting component 3 and a cleaning component 4 are respectively installed on the support frame 2. The die-cutting component 3 includes a first lead screw 301 rotatably connected to the lower surface of the support frame 2. A lifting block 302 is threadedly connected to the rod body of the first lead screw 301. Two connecting blocks 303 are welded to the outer wall of the lifting block 302. Connecting rods 304 are fixedly connected to the lower surfaces of the two connecting blocks 303. A cutting knife 305 is installed on the lower surfaces of the two connecting rods 304. A first motor 306 is installed on the upper surface of the support frame 2. Auxiliary sliders 307 are fixedly provided on the outer walls of the two connecting blocks 303. Auxiliary sliding grooves 5 are formed on the inner walls of both sides of the support frame 2. Auxiliary sliding rods 6 are welded in the two auxiliary sliding grooves 5. The auxiliary sliders 307 are slidably connected to the auxiliary sliding rods 6. The output end of the first motor 306 is fixedly connected to one end of the first lead screw 301. When the first motor 306 is started to drive the first lead screw 301 to reverse, the lifting block 302, the connecting blocks 303, the connecting rods 304 and the auxiliary sliders 307 are driven to move downward under the limitation of the auxiliary sliding grooves 5 and the auxiliary sliding rods 6, so that the cutting knife 305 also moves downward, thereby realizing the easy cutting of the foam tape on the cutting table board 1 without manual pressing and cutting, thus improving the cutting speed of the foam tape and improving the production efficiency of the foam tape.

[0024] The cleaning component 4 includes four support blocks 401 welded to both side walls of the support frame 2. A second lead screw 402 is rotatably connected between the two front support blocks 401. A first moving block 403 is threadedly connected to the rod body of the second lead screw 402. A first connecting rod 404 is fixedly connected to the lower surface of the first moving block 403. A first cleaning brush 405 is installed on the first connecting rod 404. A guide rod 406 is fixedly connected between the two rear support blocks 401. A second moving block 407 is slidably connected to the rod body of the guide rod 406.

[0026] Working principle: When in use, place the foam tape on the upper surface of the cutting table 1. Turn on the first motor 306 to drive the first lead screw 301 to reverse, thereby driving the lifting block 302, the connecting block 303, the connecting rod 304, and the auxiliary slider 307 to move downward under the limitation of the auxiliary chute 5 and the auxiliary slide rod 6. By setting the limit stop 10, it is avoided that the lifting block 302 falls off during the downward movement, so that the cutting knife 305 also moves downward, thus realizing the easy cutting of the foam tape on the cutting table 1 without manual pressing for cutting, thereby improving the cutting rate of the foam tape and thus the production efficiency of the foam tape. After cutting is completed, turn on the first motor 306 to drive the first lead screw 301 to rotate forward, thereby driving the lifting block 302, the connecting block 303, the connecting rod 304, and the auxiliary slider 307 to move upward under the limitation of the auxiliary chute 5 and the auxiliary slide rod 6, so that the cutting knife 305 also moves upward to reset. Turn on the second motor 9 to drive the second lead screw 402 to rotate forward and then reverse, thereby driving the first moving block 403, the second moving block 407, the first connecting rod 404, the second connecting rod 408, and the fixed rod 8 to move to the right and then reset under the limitation and guiding of the guide rod 406, so that the first cleaning brush 405 and the second cleaning brush 409 also move to the right and then reset. During the movement of the first cleaning brush 405 and the second cleaning brush 409, the residues of the foam tape adhered to both sides of the cutting knife 305 are cleaned, improving the practicability of the device.
