Description

Technical Field

[0001] This invention relates to the field of medical stretch film slitting and rewinding technology, specifically a slitting and rewinding machine. Background Technology

[0002] Stretch film, also known as heat shrink film, is used for the sale and transportation of various products. Its main functions are to stabilize, cover, and protect the products. Shrink film must have high puncture resistance, good shrinkage, and a certain amount of shrinkage stress. In the medical field, stretch film is also widely used due to its excellent performance.

[0003] However, existing stretch film slitting and rewinding machines typically use limiting components to position the take-up rollers. When the take-up roller is a paper tube, the impact clamping force of the limiting components may deform the end of the paper tube, causing wrinkles in the stretch film wound at the end. The limiting components may also mismatch sizes when positioning take-up rollers of different dimensions, hindering the effective fixing of the take-up rollers. After installing the blade holders, a measuring tape is needed to determine the cutting width of the stretch film, resulting in slow fixing speeds and limited operating space. Furthermore, tools are required to rotate the bolts to limit the blades when disassembling or adjusting the blade angle, further reducing blade installation efficiency. After use, the used winding rollers must be removed before replacement. If the equipment suddenly stops, the rotating take-up rollers may reverse, potentially causing the stretch film to stack.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1-12As shown, the slitting and rewinding machine of the present invention includes a slitting and rewinding machine body 1, on which an installation mechanism 2 is fixedly mounted; a clamping mechanism 3 is provided on the installation mechanism 2; an adjustment mechanism 4 is mounted on the slitting and rewinding machine body 1; a limit mechanism 5 is connected to the adjustment mechanism 4; a drive mechanism 6 is mounted on the slitting and rewinding machine body 1; a rotating mechanism 7 is connected to the drive mechanism 6; and an abutment mechanism 8 is provided on the rotating mechanism 7.

[0033] The adjustment mechanism 4 includes a mounting frame 401, which is fixedly connected to the slitting and rewinding machine body 1. A fixing plate 409 is fixedly connected to the mounting frame 401. Several sets of limiting blocks 408 are engaged with the fixing plate 409. The limiting blocks 408 are fixedly connected to the mounting plate 403. The mounting plate 403 is slidably connected to the mounting frame 401. A second ball bearing 407 is rotatably mounted on the mounting plate 403. The second ball bearing 407 is rotatably connected to a stop plate 406. The stop plate 406 is connected to the mounting frame 401 via a compression spring 405. The adjustment mechanism 4 also includes a slot 404. The mounting plate 403 is provided with a slot 404. The fixing plate 409 has a serrated structure. A marker 402 is fixedly mounted on the mounting plate 403. The marker 402 is slidably connected to the mounting frame 401.

[0034] Specifically, the limiting mechanism 5 includes a blade 501, which is rotatably connected to the mounting plate 403. A toothed block 505 is engaged with the blade 501, and the toothed block 505 is fixedly connected to the abutment rod 502. The mounting plate 403 is provided with a slot 504, and the abutment rod 502 is connected to the mounting plate 403 through a telescopic spring 503. Pulling the adjusting mechanism 4 facilitates position adjustment, and pulling the limiting mechanism 5 facilitates operator adjustment of the cutting blade angle. That is, after the operator pulls the stretch film on the winding roller and winds it onto the take-up roller, they can pull the mounting plate 403. A mounting plate 403 is disposed inside the mounting bracket 401. A stop plate 406 is connected to the mounting bracket 401 via multiple compression springs 405, and the stop plate 406 abuts against a second ball bearing 407 disposed within the mounting plate 403. When the position of the mounting plate 403 needs to be adjusted, the mounting plate 403 can be pulled, causing it to slide within the mounting bracket 401. This causes the second ball bearing 407 to press against the stop plate 406, thereby compressing the compression springs 405 and pulling the mounting plate 403 closer to the blade 501. Consequently, the mounting plate 403 slides within the mounting bracket 401. A limiting block 408 fixed on the mounting plate 403 and the mounting bracket... The fixing plate 409 installed inside 401 also changes from an engaged state to a disengaged state, making it easier for the operator to adjust the position of the mounting plate 403 when dragging it. The mounting bracket 401 has scale lines, and the mounting plate 403 has a marker 402. The marker 402 moves with the mounting plate 403, allowing the operator to control the width of the stretch film cut based on the distance between the mounting plates 403. After adjusting the position, releasing the mounting plate 403 allows the reaction force of the compression spring 405 to drive the stop plate 406 to re-engage the limiting block 408 on the mounting plate 403 into the fixing plate 409, thus preventing the blade 501 from shifting position. At the same time, it can also reduce the tedious steps of operators using tools to fix the position of the blade 501; when the blade 501 is cutting the stretch film, it is subjected to the stretch film's moving tension, and the blade 501 is subjected to the extrusion force from the stretch film, which causes the blade 501 to drive the mounting block 403 to slide closer to the fixing plate 409. Since the fixing plate 409 is already engaged with the limiting block 408 fixed on the mounting plate 403, when the mounting plate 403 presses the limiting block 408, it can make it more firmly engaged with the fixing plate 409, which also helps to prevent the blade 501 from easily causing the mounting plate 403 to shift during the cutting operation.When adjusting the angle of the blade 501, the stop rod 502 can be pulled by hand. The stop rod 502 is connected to the mounting plate 403 via a telescopic spring 503. The sliding of the stop rod 502 compresses the telescopic spring 503, causing the toothed block 505 fixed at the end of the stop rod 502 to slide from inside the blade 501 into the slot 504 provided in the mounting plate 403. Rotating the blade 501 and releasing the stop rod 502 allows the toothed block 505 to re-engage with the blade 501. This facilitates the adjustment of the blade 501's angle and improves the efficiency of the operator in installing and removing the blade 501.

[0035] Specifically, the drive mechanism 6 includes a motor 601, which is fixedly mounted on the slitting and rewinding machine body 1. The output end of the motor 601 is fixedly connected to a rotating shaft 602 via a coupling. A chuck 603 is fixedly mounted on the rotating shaft 602. A guide rod 607 is fixedly connected to the chuck 603. The chuck 603 is rotatably connected to a connecting block 604. A support rod 606 is fixedly mounted on the connecting block 604. The support rod 606 is fixedly connected to a rotating rod 605. The support rod 606 is rotatably connected to the slitting and rewinding machine body 1.

[0036] Specifically, the rotating mechanism 7 includes a turntable 701, which is fixedly connected to the support rod 606. The turntable 701 is rotatably connected to the slitting and rewinding machine body 1. Two mounting rods 702 are symmetrically fixedly installed on the turntable 701. A second hydraulic rod 703 is fixedly connected to the mounting rod 702. A fixing frame 704 is fixedly installed on the second hydraulic rod 703. A second rotating block 705 is rotatably connected to the fixing frame 704.

[0037] Specifically, the abutting mechanism 8 includes a locking rod 801, which is fixedly connected to the second rotating block 705. The locking rod 801 is fixedly connected to the rotating plate 802. A stop block 803 abuts against the rotating plate 802. A connecting shaft 804 is fixedly installed on the stop block 803. The connecting shaft 804 is rotatably connected to the fixed frame 704. A torsion spring 805 is sleeved on the connecting shaft 804. The stop block 803 is connected to the fixed frame 704 through the torsion spring 805. By turning on the control switch of the drive mechanism 6, the direction of the rotating mechanism 7 can be easily reversed. The rotation of the rotating mechanism 7 can drive the rotating anti-rotation mechanism 8 to rotate. The anti-rotation mechanism 8 is also designed to prevent the rotating mechanism 7 from rotating back when the slitting and rewinding machine body 1 is powered off. That is, when the operator is fixing the stretch film, he can first turn on the control switch of the motor 601. The motor 601 is installed on the slitting and rewinding machine body 1. The output end of the motor 601 is fixedly connected to the rotating shaft 602 through a coupling. The chuck 603 is fixedly installed on the rotating shaft 602. The guide rod 607 is fixedly installed on the chuck 603. When the motor 601 starts, the rotating shaft 602 can drive the chuck 603 to rotate, and the guide rod 607 can rotate. 7. When the chuck 603 rotates, it can abut against the rotating rod 605. The rotating rod 605 is fixedly connected to the support rod 606. A connecting block 604 is fixed on the support rod 606. The rotating rod 605 starts to rotate under the abutment of the guide rod 607. The rotating rod 605 drives the support rod 606 and the connecting block 604 to rotate. The chuck 603 rotates and engages with the connecting block 604, thereby allowing the rotating rod 605 to rotate 180 degrees. Since a turntable 701 is fixedly installed on the support rod 606, and two mounting rods 702 are symmetrically fixedly installed on the turntable 701, when the turntable 701 rotates, it can make the two mounting rods... The positions of 702 are reversed, which makes it easier for the operator to quickly replace the next winding roller after one stretch film winding roller is used up, thereby improving the performance of the slitting and rewinding machine body 1; a second hydraulic rod 703 is fixed on the mounting rod 702, and a fixing frame 704 is installed on the second hydraulic rod 703. Turning on the control switch of the second hydraulic rod 703 can cause it to move the fixing frame 704. A second rotating block 705 rotates on the fixing frame 704. When the two second rotating blocks 705 slide towards each other, they can engage with the winding roller of the stretch film, thereby facilitating the limiting of the winding roller;When the slitting and rewinding machine body 1 is started, the two guide rollers can rotate. When the stretch film winding roller contacts the guide roller, the winding roller can rotate, thereby causing the second rotating block 705 to rotate along the fixed frame 704. A locking rod 801 is fixed on the second rotating block 705, and the locking rod 801 is fixedly connected to the rotating plate 802. When the second rotating block 705 rotates, the locking rod 801 can drive the rotating plate 802 to rotate. A stop block 803 is in contact with the rotating plate 802. Since a connecting shaft 804 is fixed on the stop block 803, the rotation of the rotating plate 802 can cause the stop block 803 to rotate, thereby causing the torsion spring 805 sleeved on the connecting shaft 804 to deform. When the slitting and rewinding machine body 1 is de-energized, the stop block 803 can hook the rotating plate 802, thereby helping to prevent the stretch film from sticking together due to the rotation of the second rotating block 705.

[0038] Specifically, the installation mechanism 2 includes a fixed rod 201, which is fixedly installed on the slitting and rewinding machine body 1. A locking block 202 is engaged with the fixed rod 201, and a support frame 203 is fixedly installed on the locking block 202. A first rotating block 204 is rotatably mounted on the support frame 203. The installation mechanism 2 also includes first ball bearings 206, and a plurality of first ball bearings 206 are rotatably mounted on the support frame 203 in an annular shape. The first ball bearings 206 are in rolling connection with the first rotating block 204, and the first rotating block 204 is provided with a sliding groove 205.

[0039] Specifically, the clamping mechanism 3 includes a first hydraulic rod 307, which is fixedly mounted on the first rotating block 204. A slide rod 306 is fixedly connected to the first hydraulic rod 307. Two sliders 304 are symmetrically slidably connected to the slide rod 306. A first connecting rod 303 and a second connecting rod 305 are rotatably connected to the sliders 304. The first connecting rod 303 is rotatably connected to a limiting rod 302, and the second connecting rod 305 is rotatably connected to the first rotating block 204. A clamping plate 301 is fixedly mounted on the limiting rod 302, and the limiting rod 302 is slidably connected to the first rotating block 204. The clamping plate 301 is arc-shaped. After adjusting the position of the mounting mechanism 2, the control switch of the clamping mechanism 3 can be turned on. When the clamping mechanism 3 slides inside the mounting mechanism 2, it can limit the winding rollers of different sizes of stretch film. That is, when fixing the winding roller of the stretch film, the positions of the two locking blocks 202 on the fixing rod 201 can be adjusted first. A support frame 203 is fixed on the locking block 202. A first rotating block 204 is rotatably mounted inside the support frame 203. Several first ball bearings 206 are equidistantly mounted in a ring on the support frame 203. After the winding roller is locked onto the locking plate 301 on the first rotating block 204, the position of the other locking block 202 can be adjusted, and the first hydraulic rod 3 can be turned on. After the control switch 07 is activated, it can cause the slide rod 306 to slide within the first rotating block 204. Two sliders 304 are symmetrically connected to the slide rod 306. A first connecting rod 303 and a second connecting rod 305 are rotatably connected to each slider 304. The first connecting rod 303 is rotatably connected to the limiting rod 302, and the second connecting rod 305 is rotatably connected to the first rotating block 204. When the slide rod 306 slides, it is limited by the first connecting rod 303 and the second connecting rod 305, causing the sliders 304 to slide along the slide rod 306. The limiting rods 302 slide within the first rotating block 204. When the sliders 304 move, the two limiting rods 302 can cause the two locking plates 301 to move towards each other. When the two clamping plates 301 are closer together, it is easier for the operator to place the take-up roller on the clamping plates 301. When the first hydraulic rod 307 retracts, it drives the slide rod 306 to slide closer to the first hydraulic rod 307. This causes the slider 304 to slide along the two limiting rods 302. As the sliding distance of the two clamping plates 301 increases, they can abut against the inner wall of the take-up roller. The clamping plates 301 are arc-shaped and have rubber pads attached to them. When the take-up roller rotates with the guide roller, the first rotating block 204 can rotate along the first ball bearing 206. This facilitates the installation and fixation of the take-up roller and also limits the position of take-up rollers of different sizes.

[0040] In use, the operator first turns on the control switch of motor 601 when fixing the stretch film. Motor 601 is mounted on the body 1 of the slitting and rewinding machine. The output end of motor 601 is fixedly connected to a rotating shaft 602 via a coupling. A chuck 603 is fixedly mounted on the rotating shaft 602, and a guide rod 607 is fixedly mounted on the chuck 603. When motor 601 starts, the rotating shaft 602 drives the chuck 603 to rotate. When the guide rod 607 rotates with the chuck 603, it can abut against the rotating rod 605. The rotating rod 605 is fixedly connected to the support rod 606, and a connecting rod is fixedly mounted on the support rod 606. Block 604 and rotating rod 605 begin to rotate under the contact of guide rod 607. Rotating rod 605 drives support rod 606 and connecting block 604 to rotate. Chuck 603 rotates and engages with connecting block 604, thereby allowing rotating rod 605 to rotate 180 degrees. Since a turntable 701 is fixedly installed on support rod 606, and two mounting rods 702 are symmetrically fixedly installed on turntable 701, when turntable 701 rotates, the positions of the two mounting rods 702 can be interchanged. This allows the operator to quickly replace the next wrapping roller after one stretch film wrapping roller is used up, thereby improving the efficiency of the slitting and rewinding machine body 1. Effects: A second hydraulic rod 703 is fixed on the mounting rod 702, and a fixing frame 704 is mounted on the second hydraulic rod 703. Turning on the control switch of the second hydraulic rod 703 allows it to move the fixing frame 704. A second rotating block 705 rotates on the fixing frame 704. When the two second rotating blocks 705 slide towards each other, they can engage with the winding roller of the stretch film, thus facilitating the limiting of the winding roller. When the slitting and rewinding machine body 1 is started, the two guide rollers can be rotated. When the stretch film winding roller contacts the guide roller, the winding roller can be rotated, thereby causing the second rotating block 705 to rotate along the fixing frame 704. A locking rod 801 is fixed on the second rotating block 705. The locking rod 801 is fixedly connected to the rotating plate 802. When the second rotating block 705 rotates, the locking rod 801 can drive the rotating plate 802 to rotate. The rotating plate 802 has a stop block 803. Since the stop block 803 is fixed with a connecting shaft 804, the rotation of the rotating plate 802 can cause the stop block 803 to rotate, thereby causing the torsion spring 805 sleeved on the connecting shaft 804 to deform. When the slitting and rewinding machine body 1 is powered off, the stop block 803 can hook the rotating plate 802, which helps to prevent the stretch film from sticking together due to the rotation of the second rotating block 705.When fixing the take-up roller of the stretch film, the positions of the two locking blocks 202 on the fixing rod 201 can be adjusted first. A support frame 203 is fixed on the locking block 202, and a first rotating block 204 is rotatably fitted inside the support frame 203. Several first ball bearings 206 are rotatably fitted in a ring at equal intervals on the support frame 203. After locking the take-up roller onto the locking plate 301 provided on the first rotating block 204, the position of the other locking block 202 can be adjusted. After turning on the control switch of the first hydraulic rod 307, it can drive the slide rod 306 to slide within the first rotating block 204. Two sliders 304 are symmetrically slidably connected on the slide rod 306. A first connecting rod 303 and a second connecting rod 305 are rotatably fitted on the sliders 304. The first connecting rod 303 and the limit The first connecting rod 302 is rotatably connected to the second connecting rod 305, and the second connecting rod 305 is rotatably connected to the first rotating block 204. When the sliding rod 306 slides, it is limited by the first connecting rod 303 and the second connecting rod 305, which causes the slider 304 to slide along the sliding rod 306. The limiting rod 302 slides within the first rotating block 204. When the slider 304 moves, the two limiting rods 302 can cause the two clamping plates 301 to move towards each other. When the distance between the two clamping plates 301 becomes closer, it is easier for the operator to place the take-up roller on the clamping plate 301. When the first hydraulic rod 307 retracts, it causes the sliding rod 306 to slide closer to the first hydraulic rod 307, which causes the slider 304 to slide along the two limiting rods 302, thus increasing the sliding distance of the two clamping plates 301. The first rotating block 204 can rotate along the first ball bearing 206 when the winding roller rotates with the guide roller, so as to facilitate the installation and fixation of the winding roller and limit the movement of winding rollers of different sizes. After the operator pulls the stretch film on the winding roller and winds it onto the winding roller, the mounting plate 403 can be pulled. Several mounting plates 403 are set inside the mounting frame 401. The abutment plate 406 is connected to the mounting frame 401 through multiple compression springs 405 and abuts against the second ball bearing 407. The second ball bearing 407 is set inside the mounting plate 403. When it is necessary to adjust the position of the mounting plate 403, the abutment plate 406 can be pulled. Pulling the mounting plate 403 causes it to slide inside the mounting frame 401, and the second ball bearing 407 presses against the abutment plate 406, thereby compressing the compression spring 405. Pulling the mounting plate 403 towards the blade 501 causes it to slide inside the mounting frame 401. The limiting block 408 fixed on the mounting plate 403 and the fixing plate 409 installed inside the mounting frame 401 also change from a mutually engaged state to a separated state, making it easier for the operator to adjust the position of the mounting plate 403 when dragging it. The mounting frame 401 is provided with scale lines, and the mounting plate 403 is provided with a marker 402. The marker 402 moves with the mounting plate 403, making it easier for the operator to control the width of the stretch film cutting based on the distance between the mounting plates 403.After adjusting the position, release the mounting plate 403. Under the reaction force of the compression spring 405, the abutment plate 406 can drive the limiting block 408 on the mounting plate 403 to re-engage within the fixing plate 409. This not only helps prevent the blade 501 from shifting position but also reduces the tedious steps of the operator using tools to fix the blade 501. When cutting the stretch film, the blade 501 is subjected to the stretch film's tension, causing it to slide the mounting block 403 closer to the fixing plate 409. Since the fixing plate 409 is already engaged with the limiting block 408 fixed on the mounting plate 403, when the mounting plate 403 presses against the limiting block 408, it can make it engage with the fixing plate 409. The 09 locking mechanism is more secure, which helps prevent the blade 501 from easily displacing the mounting plate 403 during cutting. When adjusting the angle of the blade 501, the abutment rod 502 can be pulled by hand. The abutment rod 502 is connected to the mounting plate 403 via a telescopic spring 503. The sliding of the abutment rod 502 compresses the telescopic spring 503, causing the toothed block 505 fixed at the end of the abutment rod 502 to slide from the blade 501 into the slot 504 in the mounting plate 403. Rotating the blade 501 and releasing the abutment rod 502 allows the toothed block 505 to re-engage with the blade 501. This facilitates angle adjustment of the blade 501 and improves the efficiency of installing and removing the blade 501.
