Abstract
Description
Technical Field
[0001] This utility model relates to the field of slitting machine technology, specifically to a tension stabilizing mechanism for slitting machines that prevents frilly edges. Background Technology
[0002] A slitting machine is a mechanical device that cuts wide rolls of material (such as metal, plastic, paper, etc.) into narrow strips of a set width. It is widely used in the field of material processing. In the process of processing rolls of material using a slitting machine, in order to avoid the finished product having wavy edges, a tension stabilizing mechanism is usually used to stabilize the tension of the roll.
[0003] In the prior art, patent publication number CN 222947803 U discloses a winding tension stabilizing mechanism for the production of optical protective degradable films. The mechanism includes a support frame, a rotating shaft rotatably connected to the top of the middle section of the support frame, an arc-shaped groove on one side of the rotating shaft, guide grooves fixedly installed on both sides of the support frame above the rotating shaft, swing rods fixedly installed at both ends of the rotating shaft on both sides of the support frame, gears fixedly installed at both ends of the rotating shaft on the outer sides of the swing rods, a tension guide roller rotatably connected to the other end of the swing rod, both ends of the tension guide roller slidingly connected to the inside of the arc-shaped groove, a threaded rod rotatably connected to the outer side of the guide groove, and a drive motor fixedly installed on one side of the support frame. By controlling the swing angle of the tension guide roller, the actual winding tension generated is made consistent with the tension required for winding, thereby improving winding quality and increasing winding stability.
[0004] The following problems exist: While controlling the tension by adjusting the swing angle of the tension guide roller and using a single-point support tensioning method can stabilize the tension of the roll material, the single-point force causes excessive fluctuation of the roll material, requiring a longer tensioning distance to meet the tensioning requirements, resulting in low tensioning effect. Therefore, we propose a tension stabilizing mechanism for slitting machines to prevent flaring edges. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a tension stabilizing mechanism for slitting machines that prevents frilly edges. The mechanism limits and guides the roll material through the limiting components of the adjusting mechanism, and adjusts the tension of the roll material in conjunction with the operation of the adjusting mechanism. The tensioning effect is good, and the tension stabilizing mechanism and the slitting machine are modularly designed, which facilitates the disassembly and assembly of the tension stabilizing mechanism during maintenance. This can effectively solve the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a tension stabilizing mechanism for a slitting machine to prevent frilly edges, comprising a support frame and an adjustment mechanism;
[0007] Support frame: A mounting base is installed on the right side of the support frame through a mounting mechanism;
[0008] Adjustment mechanism: It includes a fixed frame, a connecting rod, a slide groove, a lead screw, a slider, and a limiting component. The upper surface of the support frame is rotatably connected to the fixed frame on both the front and rear sides via a rotating shaft. The right end of the front side of the fixed frame is rotatably connected to the connecting rod. A slide groove is opened on the front side of the support frame. The lead screw is rotatably connected inside the slide groove. The slider is threadedly connected to the outer surface of the lead screw and slidably connected inside the slide groove. The lower end of the front side of the connecting rod is rotatably connected to the rear side of the slider via a shaft. A limiting component is provided between the two fixed frames. The limiting component of the adjustment mechanism limits and guides the roll material. In conjunction with the operation of the adjustment mechanism, the tension of the roll material is adjusted, resulting in good tensioning effect. Moreover, the tension stabilization mechanism and the slitting machine are modularly designed, which facilitates the disassembly and assembly of the tension stabilization mechanism during maintenance.
[0009] Furthermore, the limiting component includes a slot, a bidirectional lead screw, a movable frame, and a turntable. The fixed frame has slots on both the left and right sides. The slots on the front fixed frame are rotatably connected to the inside of the slots. The movable frame is threaded to the upper and lower sides of the outer surface of the bidirectional lead screw. The upper end of the bidirectional lead screw is provided with a turntable to facilitate the control of the movement of the movable frame.
[0010] Furthermore, the limiting assembly also includes limiting rollers and limiting rods. The movable frame is rotatably connected to the inside of each limiting roller, and the slots on the rear fixed frame are equipped with limiting rods. The sliding hole at the rear end of the movable frame is slidably connected to the outer surface of the limiting rod on the same side, which facilitates guiding and limiting the movement of the limiting rollers.
[0011] Furthermore, the support frame is equipped with a motor, the upper end of the motor's output shaft is fixedly connected to the lower end of the lead screw, and the input end of the motor is electrically connected to the output end of an external controller to facilitate the rotation of the front lead screw.
[0012] Furthermore, the installation mechanism includes a pin, a locking block, a clearance groove, and a limiting groove. The right side of the support frame is rotatably connected to the locking block via the pin on both the front and rear sides. The left side of the mounting base is provided with clearance grooves on both the front and rear sides. The right wall of each clearance groove is provided with a limiting groove. The locking blocks are engaged with the inside of the limiting groove on the same side, which facilitates the installation of the support frame and the mounting base together.
[0013] Furthermore, the mounting mechanism also includes a worm gear, a rotating rod, a worm, and a knob. The left end of the pin is provided with a worm gear, the inside of the support frame is rotatably connected to the rotating rod, the outer surface of the rotating rod is provided with worms on both the left and right sides, and the worms are meshed with the worm gears on the same side. The front end of the rotating rod is provided with a knob to facilitate the control of the pin rotation.
[0014] Furthermore, each of the upper surfaces of the fixing frame is provided with a fixing seat, and an induction roller is rotatably connected between the two fixing seats. Tension sensors are installed on both the left and right sides of the roller shaft of the induction roller, and the output end of the tension sensor is electrically connected to the input end of an external controller to facilitate monitoring of the tension of the roll material.
[0015] Furthermore, mounting plates are fixedly connected to both the left and right sides of the upper right side of the mounting base, and positioning holes are provided on the right side of the mounting plates to facilitate the installation of the mounting base on the slitting machine.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This tension stabilizing mechanism for slitting machines that prevents frayed edges has the following advantages:
[0017] 1. By setting two sets of upper and lower corresponding limit rollers on both sides of the support frame, the roll material is limited and guided. At the same time, the drive slider moves, and the fixed frame is driven to rotate around the pivot shaft through the connecting rod, so that the position of the limit rollers on both sides changes. By adopting a dual-point tensioning method, a better tensioning effect can be obtained with a limited adjustment distance of the roll material. It can also be applied to bidirectional conveying of the roll material, making it more flexible.
[0018] 2. The tension stabilizing mechanism and the slitting machine are modularly designed. The support frame is installed on the mounting base by the engagement of the locking block and the limiting groove. When the tension stabilizing mechanism needs to be removed for maintenance, simply turn the knob. Through the meshing transmission of the worm gear and worm, the state of the locking block is changed, which can release the fixed relationship between the support frame and the mounting base. The disassembly and assembly are simple and easy to maintain. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-3 This embodiment provides a technical solution: a tension stabilizing mechanism for a slitting machine to prevent frilly edges, including a support frame 1 and an adjustment mechanism 3;
[0025] Support frame 1: A mounting base 2 is installed on the right side of the support frame 1 through the mounting mechanism 5. A fixing base 6 is provided on the upper surface of the fixing frame 31. A sensing roller 8 is rotatably connected between the two fixing bases 6. Tension sensors 7 are installed on both sides of the roller shaft of the sensing roller 8. The output end of the tension sensor 7 is electrically connected to the input end of an external controller. The tension sensor 7 can be a WLF series through-shaft tension sensor. The side of the tension sensor 7 away from the support frame 1 is fixedly connected to the fixing base 6 on the same side. The roller shaft of the sensing roller 8 passes through the bearing inside the tension sensor 7. When the roller shaft rotates, the inner ring of the bearing rotates with the roller shaft, while the tension sensor 7 remains stationary due to its fixed installation method. The core of the tension sensor 7 is an elastic body, usually made of alloy material. The two ends of the sensing roller 8 are connected to the elastic body. When the material passes through the sensing roller 8, the tension will drive the sensing roller 8, causing the elastic body to undergo slight deformation. Metal strain gauges are attached to the surface of the elastic body. The deformation will stretch or compress the metal wire inside the strain gauge. When a metal wire is stretched, its length increases and its cross-sectional area decreases, thus increasing its resistance. Conversely, when it is compressed, its resistance decreases. This change in resistance causes a small change in the voltage output of the bridge circuit, which is ultimately converted into a specific tension value.
[0026] Mounting plates 9 are fixedly connected to the upper left and right sides of the right side of the mounting base 2. Positioning holes 10 are opened on the right side of the mounting plate 9. The mounting base 2 is installed in the appropriate position of the slitting machine by bolts through the mounting plate 9 and the positioning holes 10 thereon. During the operation of the slitting machine, the tension sensor 7 transmits the tension value of the roll material monitored by the sensing roller 8 to the external controller.
[0027] Adjustment mechanism 3 includes a fixed frame 31, a connecting rod 32, a slide groove 33, a lead screw 34, a slider 35, and a limiting assembly 36. The upper surface of the support frame 1 is rotatably connected to the fixed frame 31 on both the front and rear sides via rotating shafts. The right end of the front side of the fixed frame 31 is rotatably connected to the connecting rod 32. A slide groove 33 is provided on the front side of the support frame 1. A lead screw 34 is rotatably connected inside the slide groove 33. A slider 35 is threaded onto the outer surface of the lead screw 34. The slider 35 is slidably connected inside the slide groove 33. A bellows is fixedly connected between the top wall of the slide 3 and the upper surface of the slider 35, and between the bottom wall of the slide groove 33 and the lower surface of the slider 35. The bellows are all sleeved on the outside of the lead screw 34, covering the exposed part of the outer surface of the lead screw 34. The bellows extend or contract as the slider 35 moves, protecting the transmission between the lead screw 34 and the slider 35. The lower end of the front side of the connecting rod 32 is rotatably connected to the rear side of the slider 35 through a shaft. A limiting component 36 is provided between the two fixed frames 31.
[0028] The support frame 1 is equipped with a motor 4. The upper end of the output shaft of the motor 4 is fixedly connected to the lower end of the lead screw 34. The input end of the motor 4 is electrically connected to the output end of an external controller. When tension needs to be adjusted, the motor 4 works through the control of the external controller. The output shaft of the motor 4 drives the lead screw 34 to rotate. The rotation of the lead screw 34 drives the threaded slider 35 to move along the slide groove 33. Since the length of the connecting rod 32 is fixed, the movement of the slider 35 drives the fixed frame 31 to rotate around the pivot shaft through the connecting rod 32, causing the position of the limit rollers 364 on both sides to change. By adopting a dual-point tensioning method, a better tensioning effect can be obtained with a limited adjustment distance of the roll material. It can also be applied to bidirectional conveying of the roll material, making it more flexible.
[0029] The limiting component 36 includes a slot 361, a bidirectional lead screw 362, a movable frame 363, and a turntable 366. The fixed frame 31 has slots 361 on both the left and right sides. The slots 361 on the front fixed frame 31 are rotatably connected to the bidirectional lead screw 362. The upper and lower sides of the outer surface of the bidirectional lead screw 362 are threaded to the movable frame 363. Corrugated pipes are fixedly connected between the top wall of the slot 361 and the upper surface of the upper movable frame 363, between the bottom wall of the slot 361 and the lower surface of the lower movable frame 363, and between the upper and lower movable frames 363 on the same side. Corrugated pipes are all sleeved on the outside of the bidirectional lead screw 362, covering the exposed part of the outer surface of the bidirectional lead screw 362. The corrugated pipes extend or retract as the movable frame 363 moves, protecting the transmission between the bidirectional lead screw 362 and the movable frame 363. A turntable 366 is provided at the upper end of the bidirectional lead screw 362.
[0030] The limiting assembly 36 also includes limiting rollers 364 and limiting rods 365. The movable frame 363 is rotatably connected to the limiting rollers 364 inside each of its internal parts. The slots 361 on the rear fixed frame 31 are all provided with limiting rods 365 inside each of their internal parts. The sliding hole at the rear end of the movable frame 363 is slidably connected to the outer surface of the limiting rod 365 on the same side. Then, one end of the roll material is passed from the left side of the support frame 1 to the right between the two limiting rollers 364 on the right side, and then wrapped around the upper side of the limiting roller 364 on the upper right side. The induction roller 8 passes over the upper side, then passes between the two limiting rollers 364 on the left, and moves from the upper side of the limiting roller 364 on the left to the right side of the support frame 1 until it is fed into the slitting machine. The turntable 366 is rotated, and the turntable 366 drives the bidirectional screw 362 to rotate. Under the restriction of the limiting roller 365, the rotation of the bidirectional screw 362 drives the rotating insertion port 361 of the movable frame 363 connected by threads on both sides to move towards each other, causing the two limiting rollers 364 to move towards each other and clamp and limit the roll material.
[0031] The mounting mechanism 5 includes a pin 51, a locking block 52, a clearance groove 53, and a limiting groove 54. The right side of the support frame 1 is rotatably connected to the locking block 52 via the pin 51 on both the front and rear sides. The left side of the mounting base 2 is provided with clearance grooves 53 on both the front and rear sides. A limiting groove 54 is provided on the right wall of each clearance groove 53. The locking blocks 52 are all engaged with the inside of the limiting groove 54 on the same side. The mounting mechanism 5 also includes a worm gear 55, a rotating rod 56, a worm 57, and a knob 58. A worm gear 55 is provided at the left end of each pin 51. A rotating rod 56 is rotatably connected inside the support frame 1. Worms 57 are provided on both the left and right sides of the outer surface of the rotating rod 56. Each worm 57 is engaged with the worm gear on the same side. The rotating rod 56 is connected by a 55 meshing mechanism. A knob 58 is provided at the front end of the rotating rod 56. Rotating the knob 58 causes the rotating rod 56 to rotate, and the worm gear 57 rotates accordingly. The rotation of the worm gear 57 drives the pin shaft 51 to rotate through the meshing worm wheel 55, causing the locking block 52 to rotate around the pin shaft 51. The state of the locking block 52 is adjusted to correspond with the clearance groove 53. The support frame 1 is moved, and the locking block 52 moves along the clearance groove 53 until the right side of the support frame 1 contacts the left side of the mounting base 2. At this time, the locking block 52 is inserted into the limiting groove 54. Rotating the knob 58 changes the state of the locking block 52. Through the engagement of the locking block 52 with the limiting groove 54, the support frame 1 is installed on the mounting base 2.
[0032] The working principle of the tension stabilizing mechanism for a slitting machine to prevent frilly edges provided by this utility model is as follows: The mounting base 2 is installed in a suitable position on the slitting machine using bolts through the mounting plate 9 and its positioning holes 10. Rotating the knob 58 drives the rotating rod 56 to rotate, and the worm gear 57 rotates accordingly. The rotation of the worm gear 57 drives the pin shaft 51 to rotate through the meshing worm wheel 55, causing the locking block 52 to rotate around the pin shaft 51. The state of the locking block 52 is adjusted to correspond with the clearance groove 53. The support frame 1 is moved, and the locking block 52 moves along the clearance groove 53. Move the support frame 1 until its right side contacts the left side of the mounting base 2. At this point, the locking block 52 is inserted into the limiting groove 54. Rotate the knob 58 to change the state of the locking block 52. Through the engagement of the locking block 52 and the limiting groove 54, the support frame 1 is installed on the mounting base 2. Then, pass one end of the roll material from the left side of the support frame 1 to the right between the two limiting rollers 364 on the right side, and exit from the upper side of the upper right limiting roller 364. Wrap it around the upper side of the sensing roller 8, and then pass it between the two limiting rollers 364 on the left side, exiting from the upper left limiting roller 364. The material moves from the upper side outwards to the right side of the support frame 1 until it is fed into the slitting machine. The turntable 366 rotates, causing the bidirectional lead screw 362 to rotate. Under the constraint of the limiting roller 365, the rotation of the bidirectional lead screw 362 causes the rotating insertion ports 361 of the threaded movable frames 363 on both sides to move towards each other, causing the two limiting rollers 364 to move towards each other, clamping and limiting the material. During the operation of the slitting machine, the tension sensor 7 transmits the tension value of the material monitored by the sensing roller 8 to the external controller. When tension adjustment is needed... With the control of an external controller, motor 4 operates, and the output shaft of motor 4 drives lead screw 34 to rotate. The rotation of lead screw 34 drives threaded slider 35 to move along slide groove 33. Since the length of connecting rod 32 is fixed, the movement of slider 35 drives fixed frame 31 to rotate around the pivot shaft through connecting rod 32, causing the position of limit rollers 364 on both sides to change. By adopting a dual-point tensioning method, a better tensioning effect can be obtained with a limited adjustment distance for the roll material, and it can be applied to bidirectional conveying of roll material, making it more flexible.
[0033] It is worth noting that the external controller disclosed in the above embodiments can be an STM32 series, the motor 4 can be a YP-100 series, and the tension sensor 7 can be a WLF series through-shaft tension sensor. The external controller controls the operation of the motor 4 and the tension sensor 7 using methods commonly used in the prior art.
