Description

Technical Field

[0001] This application relates to the field of slitting equipment technology, and in particular to a roll-to-roll device. Background Technology

[0002] A slitting machine is a mechanical device that cuts wide strips of paper, mica tape, or film into multiple narrow strips. It is commonly used in papermaking machinery, wire and cable mica tape production, and printing and packaging machinery. Slitting machines are particularly suitable for cutting narrow strips (non-woven fabrics, paper, insulating materials, mica tape, film, etc.).

[0003] A roll material slitting device exists in the prior art. It includes a machine body, on which are mounted a feed roller, a cutting roller, and several take-up rollers. Both ends of the feed roller, cutting roller, and each take-up roller are rotatably connected to the machine body. Each feed roller, cutting roller, and take-up roller is equipped with a drive unit to drive its own rotation. The roll material is wound onto the feed roller, with one end extending below the cutter. The cut end of the roll material is wound onto the take-up rollers. The cutting roller is located between the feed roller and the take-up rollers, and several cutters are mounted on it. Each cutter is fixedly installed on the cutting roller and contacts the roll material. In use, each drive unit is activated, causing the feed roller, cutting roller, and each take-up roller to rotate. The cutter cuts the roll material, and the rotation of the take-up rollers causes the cut roll material to be wound onto the take-up rollers.

[0004] Regarding the aforementioned technologies, since the cutter will wear down after prolonged use, and the wear of the cutter will affect the quality of the slit roll material, it is necessary for relevant personnel to disassemble and replace the cutter. However, in the existing technology, the cutter is fixedly mounted on the cutting roller. This means that when the cutter wears down, relevant personnel need to remove the entire cutting roller from the machine body in order to remove and replace the cutter on the cutting roller. Moreover, the cutting roller is installed in the middle of the machine body, which greatly increases the difficulty of disassembly for relevant personnel. Summary of the Invention

[0005] To reduce the difficulty of disassembly for relevant personnel, this application provides a roll-to-roll device.

[0006] This application provides a roll material rewinding device, which adopts the following technical solution:

[0007] A roll material slitting device includes a machine body and a cutting roller. The cutting roller is provided with a plurality of slices. The machine body is provided with a mounting frame, which is slidably connected to the machine body. The cutting roller is mounted on the mounting frame. The mounting frame is also provided with a rotating component for driving the cutting roller to rotate. The machine body is also provided with a driving component for driving the mounting frame to slide along its own sliding path, thereby detaching from the machine body.

[0008] By adopting the above technical solution, compared with the prior art which sets the cutting roller in the middle of the machine body, the present application's arrangement of the mounting frame and drive component allows relevant personnel to install the cutting roller on the mounting frame. Thus, when it is necessary to replace the cutter on the cutting roller, the drive component can drive the mounting frame to slide and detach from the machine body, thereby displacing the cutting roller outside the machine body. This allows relevant personnel to directly remove the cutting roller from the mounting frame, thus facilitating disassembly.

[0009] Preferably, the number of mounting brackets is set to two, and they are located at both ends of the machine body along its width direction. The cutting roller includes a first dividing roller and a second dividing roller. The first dividing roller and the second dividing roller are respectively mounted on the two mounting brackets, and one end of the first dividing roller is inserted into one end of the second dividing roller.

[0010] By adopting the above technical solution, the cutting roller is divided into a first sub-roller and a second sub-roller. When the cutter on the first or second sub-roller needs to be disassembled due to wear, the relevant personnel can select the first or second sub-roller corresponding to the worn cutter for disassembly based on the location of the worn cutter. Compared with the method of disassembling all cutting rollers, the setting of the first or second sub-roller in this application facilitates the replacement of the cutter by the relevant personnel, thereby improving the efficiency of cutter replacement.

[0011] Preferably, each of the mounting frames is further provided with a separating frame, which is slidably connected to the corresponding mounting frame. The first dividing roller and the second dividing roller are both mounted on the corresponding mounting frame and rotatably connected to the corresponding mounting frame. Each of the mounting frames is further provided with a separating component, which is used to drive the corresponding separating frame to slide.

[0012] By adopting the above technical solution and setting the separating frame and separating component, when it is necessary to disassemble the cutter, the relevant personnel can drive the two separating frames to move in opposite directions through the separating component, thereby separating the connection between the first and second dividing rollers, thus realizing the separation of the first and second dividing rollers. This allows the relevant personnel to disassemble the first and second dividing rollers by simply removing the end of the first and second dividing rollers that is installed with the corresponding separating frame, thereby facilitating the disassembly process and increasing the efficiency of cutting blade replacement.

[0013] Preferably, the separating component includes a pivot, a pivot frame, and an intermediate frame. One end of the pivot frame is rotatably connected to the mounting frame, the other end of the pivot frame is rotatably connected to one end of the intermediate frame, and the other end of the intermediate frame is rotatably connected to the separating frame. The pivot is used to drive the pivot frame to rotate.

[0014] By adopting the above technical solution and specifically setting the separating components, the actuator can drive the actuator frame to rotate. The rotation of the actuator frame causes the intermediate frame to be displaced at one end that is rotatably connected to the actuator frame, thereby causing the actuator frame to move and enabling the separating frame to slide relative to the mounting frame, thus achieving the separation of the first dividing roller and the second dividing roller.

[0015] Preferably, each of the mounting frames is further provided with a connecting frame, the mounting frame is sleeved on the connecting frame and slidably connected to the connecting frame, and the end of each connecting frame away from the other connecting frame is rotatably connected to the corresponding separating frame, the separating frame being slidably connected to the mounting frame through the connecting frame.

[0016] By adopting the above technical solution and configuring the connecting frame, when the intermediate frame is driven by the moving frame to rotate, the connecting frame will first slide along its own sliding direction, causing the end of the connecting frame hinged to the separating frame to slide out of the mounting frame. This allows the intermediate frame to drive the separating frame to rotate relative to the connecting frame when it continues to rotate. Consequently, the first and second dividing rollers, driven by their respective separating frames, will rotate towards the side wall of the machine body along their width direction, thus approaching the side wall of the machine body. This allows personnel to disassemble the cutters on the first and second dividing rollers without removing them, thereby facilitating operation and increasing the efficiency of cutter replacement.

[0017] Preferably, each of the connecting frames is provided with a pressure spring on the side near the other connecting frame, and the two ends of the pressure spring abut against the inner wall of the mounting frame and the separating frame, respectively.

[0018] By adopting the above technical solution and setting the pressure spring, when the actuator drives the actuator frame to rotate back, the presence of the pressure spring can reduce the probability of the connecting frame slipping first by resisting the connecting frame itself and reducing the probability of the connecting frame slipping first by its own elastic force, thereby ensuring the smooth return of the connecting frame and the separating frame.

[0019] Preferably, the body is also provided with a fixing frame and a clearance mechanism. The fixing frame is located on the sliding path of the mounting frame and abuts against the mounting frame. The clearance mechanism is used to drive the fixing frame to move so as to clear the mounting frame.

[0020] By adopting the above technical solution, the setting of the fixed frame and the avoidance mechanism enables the fixed frame to abut against the mounting frame, thereby reducing the probability of the mounting frame shaking or vibrating when the cutting roller rotates. At the same time, the setting of the avoidance mechanism enables the avoidance mechanism to avoid the displacement of the mounting frame by driving the fixed frame to move, thus ensuring the smooth displacement of the mounting frame.

[0021] Preferably, the sliding direction of the mounting bracket is vertical, the fixing bracket is slidably connected to the machine body, and the machine body is provided with a first sliding groove and a second sliding groove for the fixing bracket to slide. The extension direction of the first sliding groove is vertical, one end of the second sliding groove is connected to the top of the first sliding groove, and the second sliding groove and the first sliding groove are inclined.

[0022] By adopting the above technical solution, the setting of the first sliding groove and the second sliding groove enables the fixed frame to slide vertically upward along the sliding direction of the first sliding groove under the drive of the first sliding groove and the second sliding groove, and then enter the second sliding groove, extend the second sliding groove to slide laterally, thereby getting away from the sliding trajectory of the mounting frame and avoiding the mounting frame.

[0023] Preferably, the avoidance mechanism includes a linkage component and an avoidance component. The avoidance component includes an avoidance member, a rotating frame, and a sliding frame. The rotating frame is rotatably connected to the machine body. The rotating frame is sleeved on the sliding frame and slidably connected to the sliding frame. One end of the rotating frame is rotatably connected to a fixed frame. The avoidance member is used to drive the sliding frame to slide relative to the rotating frame. The linkage component is used to cause the fixed frame to slide along the second sliding groove.

[0024] By adopting the above technical solution and setting the avoidance mechanism, the avoidance component can drive the rotating frame to rotate, thereby causing the rotating frame to drive the sliding frame to rotate. Since one end of the sliding frame is rotatably connected to the fixed frame, and the fixed frame is restricted by the first sliding groove and the second sliding groove, the sliding direction of the end of the sliding frame rotatably connected to the fixed frame is the extension direction of the first sliding groove. Therefore, during the rotation, the sliding frame will slide relative to the fixed frame, thereby driving the fixed frame in the first sliding groove.

[0025] Preferably, the linkage assembly includes a plurality of linkage rollers, all of which are rotatably connected to the fixed frame. The linkage rollers are arranged in the direction of the extension of the first sliding groove. The sidewall of each linkage roller is in contact with the two inner sidewalls of the first sliding groove. The clearance member is used to drive the rotating frame to rotate.

[0026] By adopting the above technical solution and configuring the linkage components, when the avoidance component drives the rotating frame to rotate, both linkage rollers slide along the extension direction of the first sliding groove and rotate themselves to reduce the friction between the linkage rollers and the first sliding groove. At the same time, when the two linkage rollers move to the junction between the first sliding groove and the second sliding groove, the linkage rollers gradually enter the second sliding groove. During this process, the rotating frame rotates, gradually moves along the second sliding groove, and leaves the displacement trajectory range of the fixed frame.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The mounting frame and drive unit are designed so that relevant personnel can install the cutting roller on the mounting frame. When it is necessary to replace the cutter on the cutting roller, the drive unit can drive the mounting frame to slide and detach from the machine body, thereby moving the cutting roller outside the machine body. This allows relevant personnel to directly remove the cutting roller from the mounting frame, thus facilitating disassembly.

[0029] 2. The arrangement of the first and second dividing rollers, the connecting frame, and the separating assembly ensures that when the intermediate frame is rotated by the moving frame, the connecting frame will first slide along its own sliding direction, causing one end of the connecting frame to slide out of the mounting frame. This allows the separating frame to drive both the first and second dividing rollers to rotate towards the side wall of the machine body along its width direction when the intermediate frame continues to rotate. This allows personnel to remove the cutters on the first and second dividing rollers without disassembling them, thus facilitating operation and increasing the efficiency of cutter replacement.

[0030] 3. The design of the fixed frame and the avoidance mechanism allows the fixed frame to abut against the mounting frame, thereby reducing the probability of the mounting frame shaking or vibrating when the cutting roller rotates. At the same time, the avoidance mechanism allows the avoidance mechanism to avoid the displacement of the mounting frame by driving the fixed frame to move, thus ensuring the smooth displacement of the mounting frame.

[0038] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0039] This application discloses a roll-to-roll device. (Refer to...) Figure 1 The roll material slitting device includes a machine body 1 and a cutting roller 2, on which several cutters 3 are mounted. A mounting frame 4 is mounted on the machine body 1 and is slidably connected to it. The cutting roller 2 is mounted on the mounting frame 4, which has a rotating component 41 for driving the cutting roller 2 to rotate. A driving component 42 is also mounted on the machine body 1, which drives the mounting frame 4 to slide along its own sliding path, thereby detaching it from the machine body 1.

[0040] Reference Figure 1 The machine body 1 is equipped with a discharge roller 5 and two take-up rollers 6, which are located on both sides of the cutting roller 2 and are parallel to the cutting roller 2. The machine body 1 is also equipped with several motors, which are used to drive the corresponding discharge roller 5 and the two take-up rollers 6 to rotate.

[0041] Reference Figure 1 The number of mounting brackets 4 and driving components 42 is set to two, and they are set one-to-one. The two mounting brackets 4 are located at both ends of the machine body 1 along its own width direction. The mounting brackets 4 are slidably connected to the machine body 1 via slide rails. Optionally, the driving component 42 is a cylinder, and each mounting bracket 4 is equipped with two cylinders. The cylinder body is fixedly mounted to the bottom wall of the machine body 1 by bolts, and the piston rod of the cylinder extends vertically upward and is fixedly connected to the bottom of the corresponding mounting bracket 4 by bolts.

[0042] Reference Figure 2 and Figure 3 Each mounting frame 4 is equipped with a connecting frame 43 and a separating frame 44. The connecting frame 43 is a T-shaped frame, and the cross-sectional area of ​​the end of the connecting frame 43 away from the separating frame 44 is larger than the cross-sectional area of ​​the rest. One end of each connecting frame 43 is located inside the corresponding mounting frame 4 and is slidably connected to the mounting frame 4.

[0043] Reference Figure 2 and Figure 3 Each connecting frame 43 has a sliding rod 431 at the end furthest from the separating frame 44. One end of the sliding rod 431 is integrally formed with the connecting frame 43. The other end of the sliding rod 431 is inserted into the mounting frame 4 and slidably connected to the mounting frame 4. The extension direction of the sliding rod 431 corresponds to the sliding direction of the connecting frame 43. Each sliding rod 431 is fitted with a pressure spring 45, and the two ends of the pressure spring 45 abut against the inner walls of the connecting frame 43 and the mounting frame 4, respectively.

[0044] Reference Figure 2 and Figure 3 Each connecting frame 43 is rotatably connected to one end of the corresponding separating frame 44 via a pin. The end of the separating frame 44 that is rotatably connected to the connecting frame 43 is located inside the mounting frame 4 and is slidably connected to the mounting frame 4. This end of the separating frame 44 can slide out of the mounting frame 4.

[0045] Reference Figure 2 and Figure 4 The cutting roller 2 includes a first dividing roller 21 and a second dividing roller 22. The first dividing roller 21 and the second dividing roller 22 correspond one-to-one with two separating frames 44. The ends of the first dividing roller 21 and the second dividing roller 22 that are far apart from each other are installed on the corresponding separating frames 44 and are rotatably connected to the corresponding separating frames 44 through bearings.

[0046] Reference Figure 1 and Figure 2 The side walls of the machine body 1 are all provided with clearance grooves 11 for the displacement of the cutting roller 2. The clearance grooves 11 extend vertically upward. One end of the separating frame 44 is embedded in the clearance groove 11 and is slidably connected to the inner wall of the clearance groove 11. Optionally, the rotating component 41 is mounted on the separating frame 44 where the second dividing roller 22 is located. Optionally, in this embodiment, the rotating component 41 is a servo motor or a stepper motor. The rotating component 41 is fixedly mounted on the separating frame 44 by bolts, and the output shaft of the rotating component 41 is fixedly connected to one end of the second dividing roller 22 by a coupling.

[0047] Reference Figure 2 and 4 An insertion frame 211 is also provided on one end of the first dividing roller 21 near the second dividing roller 22. One end of the insertion frame 211 is integrally formed with the first dividing roller 21. The other end of the insertion frame 211 is inserted into the end of the first dividing roller 21. Optionally, the cross-section of the insertion frame 211 is polygonal. The cutter 3 is fixedly installed on the first dividing roller 21 or the second dividing roller 22 by bolts.

[0048] Reference Figure 2Each mounting bracket 4 is provided with a separating component 7. Each separating component 7 includes a moving element 71, a moving frame 72, and an intermediate frame 73. One end of each moving frame 72 is rotatably connected to the mounting bracket 4 via a pin, and the other end of each moving frame 72 is rotatably connected to one end of the intermediate frame 73 via a pin. The other end of each intermediate frame 73 is rotatably connected to the corresponding separating frame 44 via a pin. Optionally, in this embodiment, the moving element 71 is a rotary cylinder. The cylinder body of the rotary cylinder is rotatably connected to the mounting bracket 4 via a support and a pin, and the piston rod of the rotary cylinder is rotatably connected to the corresponding separating frame 44 via a support and a pin.

[0049] Reference Figure 1 , Figure 2 and Figure 3 Initially, the mounting frame 4 is lower than the height of the machine body 1. At this time, the connecting frame 43 is completely located within the mounting frame 4, and one end of the separating frame 44 is also located within the mounting frame 4. When the piston rod of the driving component 42 rises, making the height of the mounting frame 4 higher than the machine body 1, the piston rod of the actuator 71 begins to retract. At this time, the actuator 72 rotates under the drive of the actuator 71, which causes the intermediate frame 73 to shift, thereby causing the separating frame 44 and the connecting frame 43 to slide relative to the mounting frame 4. This causes the rotating connection between the separating frame 44 and the connecting frame 43 to slide out of the mounting frame 4. Then, the connecting frame 43 is abutted against the inner wall of the mounting frame. At this time, the connecting frame 43 is completely displaced. The separating frame 44 rotates relative to the connecting frame 43, thereby causing the first dividing roller 21 or the second dividing roller 22 to rotate, thus moving closer to the side wall of the machine body 1, facilitating the disassembly and replacement of the cutter 3 by relevant personnel.

[0050] Reference Figure 1 , Figure 2 and Figure 5 The body 1 is also equipped with a fixed frame 8 and a clearance mechanism 9. Optionally, the number of fixed frames 8 and clearance mechanisms 9 is set to two, and the fixed frames 8 and the separation frames 44 are arranged one-to-one. In the initial state, one end of the fixed frame 8 is embedded in the clearance groove 11, the fixed frame 8 is located above the separation frame 44, and abuts against the top of the separation frame 44.

[0051] Reference Figure 5 Each avoidance mechanism 9 includes a linkage component 91 and an avoidance component 92. The linkage component 91 includes several linkage rollers 911, optionally two. Each linkage roller 911 is rotatably connected to the corresponding fixed frame 8 via a pin. Each linkage roller 911 is located on the side of the corresponding fixed frame 8 closest to the other fixed frame 8, and is located at one end of the corresponding fixed frame 8 along its own length direction. The two linkage rollers 911 are arranged vertically.

[0052] Reference Figure 5 and Figure 6Each side wall of the body 1 along its width direction is provided with a first sliding groove 12 and a second sliding groove 13. Each first sliding groove 12 extends vertically and is located on one side of the clearance groove 11. Each linkage roller 911 is located within its corresponding first sliding groove 12 and is in contact with the inner side wall of the first sliding groove 12. The top of the second sliding groove 13 is connected to the top of the first sliding groove 12, and the second sliding groove 13 extends along the length of the body 1.

[0053] Reference Figure 5 and Figure 6 The inner wall of the connection between each first sliding groove 12 and the corresponding second sliding groove 13 is arc-shaped to facilitate the rotation of the corresponding linkage roller 911. Each avoidance assembly 92 includes an avoidance member 921, a rotating frame 922, and a sliding frame 923. Optionally, the avoidance member 921 is a servo motor or a stepper motor. The servo motor or stepper motor is equipped with a brake device to lock the output shaft of the servo motor or stepper motor when it stops. The brake device is prior art and will not be described in detail here.

[0054] Reference Figure 5 and Figure 6 The clearance component 921 is fixedly installed on the inner wall of the machine body 1 by bolts. The output shaft of the clearance component 921 extends out of the machine body and is fixedly connected to the rotating frame 922 by bolts. The rotating frame 922 is sleeved on one end of the sliding frame 923 and is slidably connected to the sliding frame 923. The other end of the sliding frame 923 is rotatably connected to the fixed frame 8 by a pin.

[0055] Reference Figure 1 , Figure 5 and Figure 6 In the initial state, when the separating frame 44 is located at the bottom of the clearance groove 11, the bottom end of the fixed frame 8 abuts against the top end of the separating frame 44. When it is necessary to replace the cutter 3 on the cutting roller 2, the output shaft of the clearance member 921 rotates, thereby driving the rotating frame 922 to rotate. At this time, since one end of the sliding frame 923 is rotatably connected to the fixed frame 8, and the fixed frame 8 is restricted by the first sliding groove 12 and the second sliding groove 13, the end of the sliding frame 923 that is rotatably connected to the fixed frame 8 will be displaced in the vertical direction. Therefore, the sliding frame 923 will slide relative to the rotating frame 922, thereby driving the fixed frame 8 to slide along the first sliding groove 12.

[0056] Reference Figure 2 , Figure 5 and Figure 6When the linkage roller 911 is located at the connection between the first sliding groove 12 and the second sliding groove 13, the linkage roller 911 gradually rotates and changes direction with the arc-shaped sidewall at the junction. At this time, the sliding direction of the fixed frame 8 gradually changes and eventually slides along the extension direction of the second sliding groove 13, thereby making way for the subsequent lifting of the separating frame 44.

[0057] The implementation principle of the roll material slitting device in this application embodiment is as follows: When the cutter 3 needs to be replaced, the output shaft of the avoidance member 921 rotates, thereby driving the rotating frame 922 to rotate. The rotating frame 922 drives the fixed frame 8 to move through the sliding frame 923, thereby avoiding the separating frame 44. Then, the piston rod of the driving member 42 drives the mounting frame 4 to lift, so that the slitting roller is separated from the machine body 1. Then, the relevant personnel can select the first separating roller 21 or the second separating roller 22, or the corresponding actuator 71 of the first separating roller 21 and the second separating roller 22 to work, according to the position of the cutter 3 to be replaced.

[0058] At this time, the actuator 71 drives the actuator frame 72 to rotate, which in turn causes the actuator frame 72 to move the intermediate frame 73. The intermediate frame 73 then pulls the separating frame 44 and the connecting frame 43 together, causing the rotatably connected portion of the separating frame 44 and the connecting frame 43 to slide out of the mounting frame 4. At this point, the first dividing roller 21 separates from the second dividing roller 22. Afterward, the actuator 71 continues to drive the actuator frame 72 to rotate. The separating frame 44 then flips relative to the connecting frame 43, causing the corresponding dividing roller to rotate and move closer to the side wall of the machine body 1. Once fully close, personnel approach the machine body 1 to replace the cutter 3 on the dividing roller.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
