Description

Technical Field

[0001] The present invention relates to the technical field of tape production, and particularly to a degradable tape slitting device. Background Art

[0002] Tapes can be classified into BOPP tapes, kraft paper tapes, cloth-based tapes, masking tapes, PET tapes, PVC tapes, PE foam tapes, etc. according to different base materials. At present, the key environmental protection tapes in the field are mainly masking paper tapes, kraft paper tapes, degradable tapes, plant-based tapes, and cellulose tapes. Tapes are widely used in the industrial and daily life fields. In particular, the production and usage of sealing tapes (commonly known as transparent tapes) with OPP as the base material are the largest in the world, accounting for almost 80-90% of the total tape production. They are also the most commonly used in various daily fields. To reduce the serious pollution problems of soil, water sources, air, etc. caused by industrial development globally, the use of degradable tapes has become a way of environmental protection.

[0003] In the field of tape processing, wide roll tapes are used as basic materials in the production process. Subsequently, the wide roll tapes need to be slit by a tape slitting device. Generally, when a group of tapes is wound up, it is necessary to stop the machine first, and then cut the tapes by machine or manually, so as to carry out the next slitting and winding work. However, generally, a cutting knife is directly used for cutting. Since the tape itself has a certain toughness, it may be stretched by the cutting knife before being cut, resulting in deformation and affecting the winding quality. At the same time, stopping the machine for cutting work will reduce the working efficiency of tape slitting and winding. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem of tensile deformation during the cutting of tapes in the prior art, and to propose a degradable tape slitting device.

[0005] To achieve the above purpose, the present invention adopts the following technical scheme: A degradable tape slitting device, including a base, two side plates are fixedly connected to the top of the base, and a cutting mechanism is arranged between the two side plates; The cutting mechanism includes a winding shaft, so as to automatically cut the tape when the tape reel is wound up; A discharging mechanism is arranged at the end of the winding shaft, so as to automatically discharge the wound tape reel when the tape reel is wound up.

[0006] Furthermore, the cutting mechanism includes a first turntable, and a hinge is fixedly connected to the side wall of the first turntable. A second motor is fixedly installed on the side of the hinge away from the first turntable. One end of the winding shaft facing the hinge is fixedly connected to the output shaft of the second motor. Fixed blocks are fixedly connected to the outer walls of both side plates, and a first sliding groove is penetrated through the side wall of the fixed block. A sliding plate is slidably connected to the inner wall of the first sliding groove, and a first spring is fixedly connected to the bottom of the sliding plate. The end of the first spring away from the sliding plate is fixedly connected to the inner wall of the first sliding groove. A second sliding groove is opened on the side wall of the first sliding groove. A slider is fixedly connected to the side wall of the sliding plate, and the outer wall of the slider is slidably connected to the inner wall of the second sliding groove. A cutter is fixedly connected to the top of the sliding plate.

[0007] Furthermore, the unloading mechanism includes a second turntable, and a third sliding groove is opened on the side wall of the second turntable. A sliding rod is slidably connected to the inner wall of the third sliding groove, and a first inclined block is fixedly connected to one end of the sliding rod facing the second turntable. An inner groove is opened on the inner wall of the third sliding groove, and a resisting rod is penetrated through and slidably connected to the inner wall of the inner groove. One end of the resisting rod away from the side plate is fixedly connected to a second inclined block, and a second spring is fixedly connected to the side of the second inclined block facing the resisting rod. The outer wall of the second inclined block is slidably connected to the inner wall of the inner groove. The end of the second spring away from the second inclined block is fixedly connected to the inner wall of the inner groove. A limiting inclined block is fixedly connected to the side wall of the side plate, and one end of the resisting rod facing the limiting inclined block is slidably connected in contact with the side wall of the limiting inclined block.

[0008] Furthermore, the outer wall of the sliding rod is slidably connected to the inside of the winding shaft. A diffusion block is penetrated through and slidably connected to the inside of the winding shaft, and a fourth spring is fixedly connected to the side wall of the diffusion block. The end of the fourth spring away from the diffusion block is fixedly connected to the inside of the winding shaft.

[0009] Furthermore, first motors are fixedly installed on the sides of both side plates close to each other. The output shaft of one of the first motors is fixedly connected to the center of the side wall of the first turntable, and the output shaft of the other first motor is fixedly connected to the center of the side wall of the second turntable.

[0010] Furthermore, the outer wall of the sliding plate is penetrated through and slidably connected to the side walls of both side plates. The top of the sliding plate is slidably in contact with the outer wall of the first turntable, and the top of the sliding plate is slidably in contact with the outer wall of the second turntable.

[0011] Furthermore, two first mounting plates are fixedly connected to the top of the base, and a limiting roller is rotatably connected between the two first mounting plates.

[0012] Furthermore, a strip dividing component is fixedly installed on the top of the base, and a second mounting plate is fixedly connected to the top of the base.

[0013] Furthermore, a discharge box is fixedly connected to the top of the base, and the top of the discharge box corresponds to the bottom of the take-up reel.

[0014] Compared with the prior art, the above solution has the following beneficial effects: 1. When the sliding plate fits and slides along the outer wall of the first turntable, it will drive the cutter to cut the tape. At this time, the cutter can move reciprocally left and right, thereby increasing the friction between the cutting edge of the cutter and the tape. When the cutter first contacts the tape, the cutter will compress the first spring through the sliding plate to generate a force, so that the cutter fits on the surface of the tape for friction, and then cuts the tape through the friction force, avoiding the stretching deformation of the tape before it is cut, which affects the winding quality of the tape.

[0015] 2. The inclined surface of the limit inclined block drives the abutting rod to slide, so that the second inclined block no longer positions the first inclined block. Then, the end of the take-up reel slides downward along the inside of the third chute due to gravity because it is no longer limited. Then, the tape reel wound on the outer wall of the take-up reel will slide along the outer wall of the take-up reel due to gravity, and thus will fall into the inside of the discharge box, completing the effect of automatic discharging. At the same time, the inner wall of the third chute squeezes the first inclined block, so that the sliding rod squeezes the plurality of diffusion blocks to make them diffuse outward, thereby fixing the new tape reel, which can avoid the tape reel from slipping due to the pulling force of the tape during the winding process, affecting the working quality of the strip winding of the tape. The automatic discharging reduces the downtime caused by manual discharging operations, enables the production line to keep running continuously, and improves the production efficiency.

[0020] Example 1, please refer to Figures 1 - 5 , a degradable tape slitting device, including a base 1, two side plates 2 are fixedly connected to the top of the base 1, a cutting mechanism 3 is arranged between the two side plates 2, two first mounting plates 6 are fixedly connected to the top of the base 1, a limiting roller 7 is rotatably connected between the two first mounting plates 6, a slitting assembly 8 is fixedly installed on the top of the base 1, and a second mounting plate 9 is fixedly connected to the top of the base 1; The cutting mechanism 3 includes a winding shaft 304 to automatically cut the tape when the winding of the tape reel is completed. The cutting mechanism 3 includes a first turntable 301, and a hinge 302 is fixedly connected to the side wall of the first turntable 301. A second motor 303 is fixedly installed on the side of the hinge 302 away from the first turntable 301. One end of the winding shaft 304 facing the hinge 302 is fixedly connected to the output shaft of the second motor 303. Fixed blocks 305 are fixedly connected to the outer walls of both side plates 2, and a first chute 306 is penetrated through the side wall of the fixed block 305. A sliding plate 307 is slidably connected to the inner wall of the first chute 306, and a first spring 308 is fixedly connected to the bottom of the sliding plate 307. The end of the first spring 308 away from the sliding plate 307 is fixedly connected to the inner wall of the first chute 306. A second chute 309 is opened on the side wall of the first chute 306. A slider 310 is fixedly connected to the side wall of the sliding plate 307, and the outer wall of the slider 310 is slidably connected to the inner wall of the second chute 309. A cutter 311 is fixedly connected to the top of the sliding plate 307. First motors 5 are fixedly installed on the sides of the two side plates 2 close to each other. The output shaft of one of the first motors 5 is fixedly connected to the center of the side wall of the first turntable 301, and the output shaft of the other first motor 5 is fixedly connected to the center of the side wall of the second turntable 401; During the production of the tape, to ensure the production output, wide roll tape is used as the basic material in the production process. Subsequently, it needs to be slit by a tape slitting device. When slitting the wide roll tape is required, first install the tape reel on the outer wall of the winding shaft 304, and the distance between them is consistent with that of the multiple slitting assemblies 8. Then install the wide roll tape on the unwinding shaft between the two second mounting plates 9. Then pull out the outer end of the wide roll tape through between the two limiting rollers 7 at the proximal end, and then through between the slitting assembly 8 and the other two limiting rollers 7. The slitting assembly 8 can cut the wide roll tape, dividing the wide roll tape into multiple narrow tapes, thus achieving the function of slitting the wide roll tape. Then fix some of the slit narrow tapes on the corresponding tape reels, and fix the staggered part of the narrow tapes on the tape reels on another winding shaft 304. After that, power on the device to drive the output of the second motor 303 connected to the winding shaft 304 near the unwinding shaft. Then the output shaft of the second motor 303 will drive the winding shaft 304 to rotate, and drive the tape reel on its outer wall to perform slitting and winding work. When the tape reel winds up to the maximum diameter, at this time, a new tape reel needs to be replaced. At this time, drive the two first motors 5 to output. When the two first motors 5 output, the rotation of their output shafts will drive the corresponding first turntable 301 and second turntable 401 to rotate half a circle with the first motor 5 as the axis.

[0021] In the present application, the two first motors 5 can be driven to rotate half a circle by using a single chip microcomputer or FPGA to control the operation of the motor output end, so as to realize the automatic rotation of the motor by program setting, and rotate half a circle or a set angle during operation. In addition, this function can also be realized by the controller provided by the motor. It is common sense to control the motor to rotate half a circle and pause after power is turned on. This point will not be elaborated in the present application, and it can be realized by controlling the motor to rotate regularly by program.

[0022] During the rotation, the top of the sliding plate 307 is always in contact with the outer wall of the first rotating disk 301 and the second rotating disk 401 due to the elastic force of the first spring 308. During the rotation of the first rotating disk 301 and the second rotating disk 401, the sliding plate 307 is squeezed by the outer wall of the first rotating disk 301 and the second rotating disk 401, thereby sliding downward along the inner wall of the first sliding groove 306. During the process, the first spring 308 is compressed. When the first motor 5 drives the first rotating disk 301 and the second rotating disk 401 to rotate, the sliding plate 307 is pressed by the outer wall of the first rotating disk 301 and the second rotating disk 401. When the rotation of 401 is completed, the tape will be driven to the tape roll that contacts the outer walls of the two take-up shafts 304 at the same time. At this time, the sliding plate 307 slides to the outer wall inclined surface of the first turntable 301 and the second turntable 401, and the elastic force of the first spring 308 is released, which will simultaneously drive the sliding plate 307 to slide upward along the inside of the first slide groove 306, so that the sliding plate 307 drives the blade of the cutter 311 to cut the tape. The distance between the first turntable 301 and the second turntable 401 is greater than the length of the cutter 311.

[0023] The first spring 308 of the first embodiment of the present invention is used to press the first spring 308 of the first embodiment of the present invention ...

[0024] For example 2, please refer to Figures 1 - 7 On the basis of the first embodiment, in this embodiment, a discharging mechanism 4 is provided at the end of the reel 304, so that when the reel of the adhesive tape is completed, the reel of the adhesive tape can be automatically unloaded; The unloading mechanism 4 includes a second turntable 401, and a third chute 402 is formed in the side wall of the second turntable 401. A sliding rod 403 is slidably connected to the inner wall of the third chute 402, and a first inclined block 404 is fixedly connected to one end of the sliding rod 403 facing the second turntable 401. An inner groove 405 is formed in the inner wall of the third chute 402, and a resisting rod 406 is slidably connected through the inner wall of the inner groove 405. A second inclined block 407 is fixedly connected to one end of the resisting rod 406 away from the side plate 2, and a second spring 408 is fixedly connected to one side of the second inclined block 407 facing the resisting rod 406. The outer wall of the second inclined block 407 is slidably connected to the inner wall of the inner groove 405, and the end of the second spring 408 away from the second inclined block 407 is fixedly connected to the inner wall of the inner groove 405. A limiting inclined block 409 is fixedly connected to the side wall of the side plate 2, and one end of the resisting rod 406 facing the limiting inclined block 409 is slidably attached to the side wall of the limiting inclined block 409. The outer wall of the sliding rod 403 is slidably connected to the inside of the winding shaft 304. A diffusing block 410 is slidably connected through the inside of the winding shaft 304, and a fourth spring 411 is fixedly connected to the side wall of the diffusing block 410. The end of the fourth spring 411 away from the diffusing block 410 is fixedly connected to the inside of the winding shaft 304. The outer wall of the sliding plate 307 is slidably connected through the side walls of the two side plates 2. The top of the sliding plate 307 is slidably attached to the outer wall of the first turntable 301 and the outer wall of the second turntable 401. A discharge box 10 is fixedly connected to the top of the base 1, and the top of the discharge box 10 corresponds to the bottom of the winding shaft 304; After the winding of a tape reel is completed, when the second turntable 401 is rotated by a certain angle by controlling the first motor 5, the end of the abutting rod 406 away from the second inclined block 407 will come into contact with the limiting inclined block 409. Since one side of the width of the limiting inclined block 409 is wide and the other side is narrow, when the abutting rod 406 starts to contact the limiting inclined block 409, it will fit against its narrowest end. During the subsequent rotation process, it will slide from the narrowest end of the limiting inclined block 409 to the widest end, so that the abutting rod 406 slides outward along the inner wall of the inner groove 405. At the same time, the second spring 408 will be compressed. When the abutting rod 406 slides a certain distance, at this time, the abutting rod 406 will drive the second inclined block 407 to contract into the inner part of the inner groove 405, so that the second inclined block 407 no longer positions the first inclined block 404. Then, the end of the winding shaft 304 slides downward along the inside of the third chute 402 due to gravity as it is no longer restricted. At the same time, the corresponding second motor 303 will deflect through the hinge 302. Then, the tape reel wound on the outer wall of the winding shaft 304 will slide along the outer wall of the winding shaft 304 due to gravity, and thus will fall off the outer wall of the winding shaft 304 into the inside of the discharge box 10, achieving the effect of automatic discharging. After that, when the end of the abutting rod 406 crosses the limiting inclined block 409 and is separated from it, the second spring 408 can drive the second inclined block 407 to slide back to its original position. Then, the staff installs a new tape reel on the winding shaft 304 that is not in the winding process. After the installation is completed, the end of the winding shaft 304 is lifted to make it slide along the third chute 402 for reinstallation work. During this process, the inclined surface of the first inclined block 404 will squeeze the inclined surface of the second inclined block 407, causing the second inclined block 407 to slide briefly into the inner part of the inner groove 405. After the winding shaft 304 is installed, the second inclined block 407 will return to its original position by the elastic force of the second spring 408, thus positioning the first inclined block 404. At the same time, the inner wall of the third chute 402 squeezes the first inclined block 404, causing the sliding rod 403 to slide along the inner wall of the winding shaft 304. During the sliding process, it will squeeze a plurality of diffusing blocks 410, enabling the plurality of diffusing blocks 410 to achieve the effect of outward diffusion, so as to squeeze the inner wall of the new tape reel on the outer wall of the winding shaft 304, and at the same time compress the corresponding fourth spring 411 to provide the force required for subsequent resetting, which can prevent the tape reel from slipping due to the pulling force of the tape during the winding process and affecting the working quality of the strip winding of the tape.

[0025] The working principle of the present invention is as follows: First, install the tape reel on the outer wall of the take-up reel 304, and the distance between them is consistent with that of the multiple slitting assemblies 8. Then, install the wide roll tape on the pay-off reel between the two second mounting plates 9. Next, pull out the outer end of the wide roll tape through between the two limiting rollers 7 at the proximal end, and then through between the slitting assembly 8 and the other two limiting rollers 7. The wide roll tape can be cut by the slitting assembly 8, so that the wide roll tape is subdivided into multiple narrow tapes, thus achieving the function of slitting the wide roll tape. Then, fix some of the slit narrow tapes on the corresponding tape reels, and fix the staggered part of the narrow tapes on the tape reels on the other take-up reel 304. After that, power on the device to drive the output of the second motor 303 connected to the take-up reel 304 close to the pay-off reel side. Then, the output shaft of the second motor 303 will drive the take-up reel 304 to rotate, and the tape reel on its outer wall will be driven by the take-up reel 304 to perform slitting and winding operations. When the tape reel winds up to the maximum diameter, it is necessary to replace the new tape reel at this time. At this time, drive the output of the two first motors 5. When the two first motors 5 output, the rotation of their output shafts will drive the corresponding first turntable 301 and second turntable 401 to rotate half a circle around the first motor 5 as the axis. During the rotation process, since the sliding plate 307 is elastically forced by the first spring 308, its top always slides along the outer walls of the first turntable 301 and the second turntable 401. During the rotation of the first turntable 301 and the second turntable 401, the sliding plate 307 will be squeezed by the outer walls of the first turntable 301 and the second turntable 401, so as to slide downward along the inner wall of the first chute 306. During this process, the first spring 308 will be compressed. When the first motor 5 drives the first turntable 301 and the second turntable 401 to complete the rotation, the tape will be driven to simultaneously contact the tape reels on the outer walls of the two take-up reels 304. At this time, the sliding plate 307 slides to the outer wall inclined surface of the first turntable 301 and the second turntable 401. Through the elastic force release of the first spring 308, the sliding plate 307 will be driven to slide upward along the inside of the first chute 306 at the same time, so that the sliding plate 307 drives the cutting edge of the cutter 311 to cut the tape. The distance between the first turntable 301 and the second turntable 401 is greater than the length of the cutter 311; During the upward sliding process of the sliding plate 307, at the same time, the slider 310 fixedly connected to its outer wall slides along the inner wall of the second chute 309, so that during the process of the sliding plate 307 driving the cutter 311 to cut the tape, it will move left and right reciprocally at the same time, thereby increasing the friction between the cutting edge of the cutter 311 and the tape. When the cutter 311 first contacts the tape, at this time, the cutter 311 will make the cutter 311 fit on the tape surface for friction through the force generated by the sliding plate 307 compressing the first spring 308, and then cut the tape through the frictional force, so as to avoid the stretching deformation of the tape before it is cut, which affects the winding quality of the tape; When the second turntable 401 is rotated to a certain angle by controlling the first motor 5, one end of the abutting rod 406 away from the second inclined block 407 will come into contact with the limiting inclined block 409. Since the width of the limiting inclined block 409 is wider on one side and narrower on the other side, when the abutting rod 406 starts to contact the limiting inclined block 409, it will fit against its narrowest end. During the subsequent rotation process, it will slide from the narrowest end of the limiting inclined block 409 to the widest end, causing the abutting rod 406 to slide outward along the inner wall of the inner groove 405. At the same time, the second spring 408 will be compressed. When the abutting rod 406 slides a certain distance, the abutting rod 406 will drive the second inclined block 407 to contract into the interior of the inner groove 405, so that the second inclined block 407 no longer positions the first inclined block 404. Then, the end of the winding shaft 304 slides downward along the interior of the third chute 402 due to gravity as it is no longer restricted, and at the same time, the corresponding second motor 303 deflects through the hinge 302. Then, the tape reel wound on the outer wall of the winding shaft 304 slides along the outer wall of the winding shaft 304 due to gravity and thus falls off the outer wall of the winding shaft 304 into the interior of the unloading box 10, achieving the effect of automatic unloading.
