Description

Technical Field

[0001] This utility model relates to the technical field of kraft paper tape processing equipment, and more specifically to a high tensile strength kraft paper tape processing equipment. Background Technology

[0002] Kraft paper tape is an adhesive sealing tape made of kraft paper. It has good adhesion and durability. Kraft paper itself has high tensile strength and can withstand certain pressure and weight. Its adhesive can firmly adhere to various surfaces, ensuring the safety of packaging. It is widely used in packaging, sealing, labeling, repair and other fields. In the production and processing of kraft paper tape, a slitting device is needed to cut the kraft paper tape on the master roll into appropriate widths. A slitting machine is a mechanical device that cuts wide paper, mica tape or film into multiple narrow strips of material. It is commonly used in papermaking machinery, wire and cable mica tape, and printing and packaging machinery.

[0003] Insufficient technology: Existing slitting machines mostly have a fixed blade position during use, which makes it inconvenient to adjust the blade position and thus cannot flexibly slit kraft paper tape of different widths; in addition, the kraft paper tape contains adhesive, which adheres to the blade during the slitting process, affecting the slitting quality and causing rough edges to appear on the kraft paper tape. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high tensile strength kraft paper tape processing equipment to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high tensile strength kraft paper tape processing equipment, comprising a main body, and further comprising: an installation mechanism, an adjustment mechanism, a slitting mechanism, and a kraft paper tape body. The inner side wall of the main body is fixedly connected to the side of the adjustment mechanism, the bottom end of the adjustment mechanism is movably connected to the top end of the installation mechanism, the side of the slitting mechanism is movably connected to the side of the installation mechanism, and the side of the kraft paper tape body is movably connected to the side of the main body.

The adjustment mechanism includes a slide rail, the side of which is fixedly connected to the inner wall of the side of the housing. The mounting mechanism includes a mounting bracket, the top of which is fixedly connected to a slider. The side of the slider is movably connected to the inner wall of the side of the slide rail. A servo motor is fixedly connected to the side of the housing. A threaded rod is fixedly connected to the output shaft of the servo motor. A threaded block is threadedly connected to the side of the threaded rod. A through groove is provided on the side of the mounting bracket corresponding to the position of the threaded rod. A placement groove is provided on the side of the through groove. The side of the placement groove is movably connected to the side of the threaded block. The slitting mechanism includes a slitting blade, the side of which is movably sleeved with the inner wall of the side of the mounting bracket.

[0006] Furthermore, a second mounting hole is provided at the top of the placement groove, a return spring is fixedly connected to the top of the second mounting hole, a fixing pin is fixedly connected to the bottom of the return spring, a fixing hole is provided at the top of the threaded block, and the side of the fixing hole is movably connected to the side of the fixing pin.

[0007] Furthermore, a first mounting hole is provided at the top of the second mounting hole, an electromagnet is fixedly connected to the top of the first mounting hole, a connecting rod is fixedly connected to the top of the fixing pin, and an iron sheet is fixedly connected to the top of the connecting rod.

[0008] Furthermore, a mounting ring is fixedly connected to the side of the slitting blade, and the side of the mounting ring is movably sleeved with the inner wall of the side of the mounting bracket. A slot is opened on the side of the slitting blade. A drive motor is fixedly connected to the side of the housing. A transmission shaft is fixedly connected to the output shaft of the drive motor. The side of the transmission shaft is movably connected to the side of the slot.

[0009] Furthermore, a mounting ring is fixedly connected to the side of the slitting blade, and the side of the mounting ring is movably sleeved with the inner wall of the side of the mounting bracket. A slot is opened on the side of the slitting blade. A drive motor is fixedly connected to the side of the housing. A transmission shaft is fixedly connected to the output shaft of the drive motor. The side of the transmission shaft is movably connected to the side of the slot.

[0010] Furthermore, the bottom cross-section of the grinding block is V-shaped, and the bottom end of the grinding block is arc-shaped.

[0011] Furthermore, a guide roller is movably sleeved on the inner side wall of the housing, and a paper separating roller is movably sleeved on the inner side wall of the housing. The tension rollers and guide rollers on both sides are symmetrically distributed along the center of the slitting mechanism, and the bottom end of the tension roller and the top end of the guide roller are at the same height.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, based on usage requirements, for slitting blades that do not require position adjustment, uses an electromagnet inside the corresponding mounting mechanism to generate magnetic force, causing the electromagnet to attract the iron sheet, which in turn causes the connecting rod to move the fixing pin out of the fixing hole and into the second mounting hole. When the threaded rod rotates, the threaded block rotates with the threaded rod and cannot drive the corresponding mounting mechanism to move laterally. For slitting blades that require position adjustment, the electromagnet inside the corresponding mounting mechanism is de-energized, and the reset spring pushes the fixing pin into the fixing hole to limit the threaded block. When the threaded rod rotates, the threaded block remains stationary. The servo motor is started to drive the threaded rod to rotate, causing the threaded block to drive the mounting frame to move laterally through the thread, thereby adjusting the distance between adjacent slitting blades and keeping the excess slitting blades located on both sides of the threaded rod without participating in slitting. This improves the flexibility of the equipment and allows for slitting into kraft paper tape of different widths.

[0014] 2. This utility model uses a drive motor to rotate a transmission shaft, which in turn engages with the drive shaft via a slot to rotate a slitting blade. The slitting blade rotates in the opposite direction to the conveying direction of the kraft paper tape body, causing the slitting blade to rotate and cut the kraft paper tape body. Meanwhile, a pressure spring pushes a grinding block downwards, causing the bottom of the grinding block to press tightly against the top of the slitting blade. As the slitting blade rotates, the grinding block sharpens the blade edge to maintain its sharpness and scrapes away impurities from the surface of the slitting blade, which helps improve the quality of the slitting kraft paper tape and avoids rough edges.

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The high tensile strength kraft paper tape processing equipment involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Reference Figures 1 to 8This utility model provides a high tensile strength kraft paper tape processing equipment, including a main body 1, and further including: an installation mechanism 2, an adjustment mechanism 3, a slitting mechanism 4, and a kraft paper tape body 5. The inner side wall of the main body 1 is fixedly connected to the side of the adjustment mechanism 3, the bottom end of the adjustment mechanism 3 is movably connected to the top end of the installation mechanism 2, the side of the slitting mechanism 4 is movably connected to the side of the installation mechanism 2, and the side of the kraft paper tape body 5 is movably connected to the side of the main body 1. The main body 1 includes a housing 101. A tension roller 102 is movably sleeved on the side of the machine housing 101. The side of the tension roller 102 is movably connected to the side of the kraft paper tape body 5. The adjustment mechanism 3 includes a slide rail 301, the side of which is fixedly connected to the inner wall of the side of the machine housing 101. The mounting mechanism 2 includes a mounting frame 201, the top of which is fixedly connected to a slider 210. The side of the slider 210 is movably connected to the inner wall of the side of the slide rail 301. A servo motor 302 is fixedly connected to the side of the machine housing 101, and a threaded rod 3 is fixedly connected to the output shaft of the servo motor 302. 03. A threaded block 304 is threadedly connected to the side of the threaded rod 303. A through groove 207 is provided on the side of the mounting bracket 201 corresponding to the position of the threaded rod 303. A placement groove 209 is provided on the side of the through groove 207. The side of the placement groove 209 is movably connected to the side of the threaded block 304. The slitting mechanism 4 includes a slitting blade 401. The side of the slitting blade 401 is movably sleeved with the inner wall of the side of the mounting bracket 201. Multiple mounting brackets 201 are installed at the bottom of the slide rail 301 by a slider 210. The threaded block 304 is installed in the placement groove 209. Inside 9, the diameter of the through groove 207 is larger than the diameter of the threaded rod 303. During use, the servo motor 302 drives the threaded rod 303 to rotate, and the threaded block 304 drives the mounting frame 201 to move laterally through the thread, thereby adjusting the distance between adjacent slitting blades 401. The extra slitting mechanism 4 is located on both sides of the threaded rod 303 and does not participate in the slitting of the kraft paper tape body 5. During use, the kraft paper tape body 5 passes through the tension rollers 102 on both sides and is conveyed to the left. The slitting blade 401 slits the kraft paper tape body 5.

[0026] The top of the placement groove 209 is provided with a second mounting hole 214. A return spring 205 is fixedly connected to the top of the second mounting hole 214. A fixing pin 202 is fixedly connected to the bottom of the return spring 205. The top of the threaded block 304 is provided with a fixing hole 305. The side of the fixing hole 305 is movably connected to the side of the fixing pin 202. When the position of the slitting blade 401 needs to be adjusted, the return spring 205 inside the corresponding mounting mechanism 2 pushes the fixing pin 202 to insert into the fixing hole 305 to limit the threaded block 304. When the threaded rod 303 rotates, the threaded block 304 remains fixed, thereby causing the threaded block 304 to drive the mounting bracket 201 to move laterally through the thread.

[0027] The second mounting hole 214 has a first mounting hole 212 at its top. An electromagnet 206 is fixedly connected to the top of the first mounting hole 212. A connecting rod 203 is fixedly connected to the top of the fixing pin 202. An iron piece 213 is fixedly connected to the top of the connecting rod 203. Without adjusting the position cutting blade 401, the electromagnet 206 inside the corresponding mounting mechanism 2 is energized to generate magnetic force, which causes the electromagnet 206 to attract the iron piece 213, causing the connecting rod 203 to move the fixing pin 202 out of the fixing hole 305 and into the second mounting hole 214. When the threaded rod 303 rotates, the threaded block 304 rotates with the threaded rod 303 and cannot drive the corresponding mounting mechanism 2 to move laterally.

[0028] The slitting blade 401 has a mounting ring 404 fixedly connected to its side, and the side of the mounting ring 404 is movably sleeved with the inner side wall of the mounting bracket 201. The side of the slitting blade 401 has a slot 405. The side of the housing 101 is fixedly connected to a drive motor 402, and the output shaft of the drive motor 402 is fixedly connected to a transmission shaft 403. The side of the transmission shaft 403 is movably connected to the side of the slot 405, and the slot 405 can move laterally along the transmission shaft 403. During the process, the drive motor 402 drives the transmission shaft 403 to rotate. The slot 405 and the transmission shaft 403 mesh with each other to drive the slitting blade 401 to rotate. The rotation direction of the slitting blade 401 is opposite to the conveying direction of the kraft paper tape body 5, so that the slitting blade 401 rotates to cut the kraft paper tape body 5.

[0029] The mounting bracket 201 has a mounting groove 211 on its top inner wall. A pressure spring 208 is fixedly connected to the top of the mounting groove 211. A sharpening block 204 is fixedly connected to the bottom of the pressure spring 208. The bottom of the sharpening block 204 is fixedly connected to the top of the slitting blade 401. The pressure spring 208 pushes the sharpening block 204 downward so that the bottom of the sharpening block 204 is in close contact with the top of the slitting blade 401. As the slitting blade 401 rotates, the sharpening block 204 sharpens the blade edge of the slitting blade 401 to keep it sharp and scrapes away debris from the surface of the slitting blade 401.

[0030] The bottom section of the grinding block 204 is V-shaped, and the bottom end of the grinding block 204 is arc-shaped, ensuring that the bottom of the grinding block 204 is in close contact with the top of the slitting blade 401.

[0031] The inner side wall of the housing 101 is movably fitted with a guide roller 104 and a paper separating roller 103. The tension rollers 102 and the guide rollers 104 on both sides are symmetrically distributed along the center of the slitting mechanism 4. The bottom end of the tension roller 102 is at the same height as the top end of the guide roller 104. The kraft paper tape body 5 passes through the right guide roller 104, the right tension roller 102, the left tension roller 102 and the left guide roller 104 in sequence from the right side, tightening the kraft paper tape body 5. The paper separating roller 103 separates the adjacent kraft paper tapes after slitting, which facilitates winding and recycling.

[0032] The working principle of this utility model is as follows: According to usage requirements, for slitting blades 401 that do not require position adjustment, the electromagnet 206 inside the corresponding mounting mechanism 2 is energized to generate magnetic force, causing the electromagnet 206 to attract the iron sheet 213, which in turn causes the connecting rod 203 to move the fixing pin 202 out of the fixing hole 305 and into the second mounting hole 214. When the threaded rod 303 rotates, the threaded block 304 rotates with it, but cannot move the corresponding mounting mechanism 2 laterally. For slitting blades 401 that require position adjustment, the electromagnet 206 inside the corresponding mounting mechanism 2 is de-energized, and the reset spring 205 pushes the fixing pin 202 into the fixing hole 305 to limit the threaded block 304. When the threaded rod 303 rotates, the threaded block 304 remains stationary. The servo motor 302 is started to drive the threaded rod 303 to rotate, causing the threaded block 304 to move the mounting bracket 201 laterally through the thread, thereby adjusting the distance between adjacent slitting blades 401. The excess slitting blade 401 is positioned on both sides of the threaded rod 303 and does not participate in slitting. The kraft paper tape body 5 passes sequentially from the right side through the right guide roller 104, the right tension roller 102, the left tension roller 102, and the left guide roller 104, tightening the kraft paper tape body 5. The drive motor 402 drives the transmission shaft 403 to rotate, and the slitting blade 401 rotates through the slot 405 meshing with the transmission shaft 403. The direction of rotation of the slitting blade 401 is as follows: Opposite to the conveying direction of the kraft paper tape body 5, the slitting blade 401 rotates to cut the kraft paper tape body 5, and the pressure spring 208 pushes the grinding block 204 downward so that the bottom end of the grinding block 204 is in close contact with the top of the slitting blade 401. As the slitting blade 401 rotates, the grinding block 204 grinds the blade edge of the slitting blade 401 to keep it sharp and scrapes away the debris on the surface of the slitting blade 401. The paper separating roller 103 separates the adjacent kraft paper tapes after slitting.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
