Description

Technical Field

[0001] This technical solution relates to the field of cutting and slitting machines, and specifically refers to a cutting device for a cutting and winding machine. Background Technology

[0002] A cutting and winding machine is an automated device specifically designed for the efficient processing of materials such as paper (e.g., kraft paper). Through precise cutting and winding functions, it cuts wide-width raw paper to preset dimensions and then synchronously winds it into a spool by a constant tension control system, ensuring uniform cutting width and neat and tight winding.

[0003] Traditional cutting devices suffer from cumbersome operation and insufficient precision when adjusting the gap between the cutter rollers. When adapting to paper materials of different thicknesses or materials, existing structures often require the coordinated adjustment of multiple components or the disassembly of the device to change the cutting pressure. This not only reduces production efficiency but also easily affects the parallelism of the cutter rollers due to human error, resulting in uneven cuts or even accelerated blade wear. Adjusting the gap between the cutter rollers is also troublesome. Summary of the Invention

[0004] This technical solution provides a cutting device for a cutting and winding machine to improve the problem of cumbersome operation when adjusting the gap between the cutter rollers.

[0005] The purpose of this technical solution is achieved as follows:

[0006] A cutting device for a cutting and winding machine includes a frame, the frame being equipped with a cutting mechanism, the cutting mechanism comprising:

[0007] The first cutter roller is disposed on the frame and rotatably disposed relative to the frame;

[0008] The second cutter roller is disposed on the frame and rotatably disposed relative to the frame. The second cutter roller is tangentially engaged with the first cutter roller, and paper material passes between the first cutter roller and the second cutter roller.

[0009] A strip-cutting drive unit, which is disposed on the frame, is used to drive the first cutter roller to rotate so that it cooperates with the second cutter roller to cut the paper material into multiple strips;

[0010] The frame is also provided with a clamping adjustment assembly, which includes an adjustment rod that is threadedly engaged with the first cutter roller. By rotating the adjustment rod, the first cutter roller can be moved relative to the second cutter roller.

[0011] Through the above technical solution, when the cutting device of a cutting and rewinding machine is in normal use, the cutting drive component drives the first cutter roller to rotate, and the paper material is continuously cut into multiple strips when it passes through the paper material channel formed by the tangency of the two. The adjusting rod of the pressure adjustment component precisely controls the axial displacement of the first cutter roller through threaded transmission, realizing stepless adjustment of the paper material channel, replacing the traditional adjustment structure. Only by rotating the adjusting rod can the cutting pressure and channel size be quickly changed, maintaining cutting accuracy, improving the adaptability of paper materials of different thicknesses and the efficiency of equipment maintenance.

[0012] Preferably, the clamping adjustment assembly includes an adjustment frame, an adjustment seat, and an adjustment rod disposed on the frame. There are two adjustment frames, which are located on opposite sides of the frame along the rotation axis of the first cutter roller. The adjustment seat is slidably connected to each adjustment frame. The adjustment seat is fixedly connected to the first cutter roller, and the adjustment rod is threadedly engaged with the adjustment seat.

[0013] With the above technical solution, two adjusting frames are symmetrically distributed on both sides of the frame. The adjusting seat forms a sliding pair with the adjusting frame through a slide rail structure and is rigidly connected to both ends of the first cutter roller. The adjusting rod passes through the adjusting seat to form a precision threaded transmission pair. When the adjusting rod is rotated, the adjusting seat is driven to move linearly along the adjusting frame according to different thread directions, thereby driving the first cutter roller to move as a whole, thus realizing the adjustment of the paper material channel.

[0014] Preferably, the first cutter roller includes annular blades arranged equidistantly along the axial direction, and the surface of the second cutter roller is provided with annular grooves that are equidistantly spaced along the axial direction and are fitted one-to-one with the annular blades.

[0015] Through the above technical solution, the axially equidistant annular blades of the first cutter roller and the corresponding annular grooves of the second cutter roller form a precise fitting structure, ensuring the dynamic alignment accuracy of the blades and grooves. The annular blades cut into the grooves in a shearing manner to complete continuous slitting. Multiple cutting units can operate in parallel through axially equidistant arrangement, ensuring the consistency of the strip width. The curved interlocking method between the annular blades and the grooves can disperse shear stress and reduce local wear of the blades.

[0016] Preferably, the frame is provided with a guiding mechanism, the guiding mechanism comprising:

[0017] The drive roller is rotatably mounted on the frame;

[0018] An adjusting roller is rotatably mounted on the frame, with its axis of rotation parallel to the drive roller;

[0019] A pressure regulating assembly is disposed on the frame. The pressure regulating assembly includes a pressure regulating frame and a pressure regulating rod disposed on the frame. The pressure regulating rod is threadedly engaged with the adjusting roller, so that the rotation of the pressure regulating rod drives the adjusting roller to move relative to the drive roller.

[0020] The frame is equipped with a feeding roller, which is rotatably mounted on the frame and used to guide the paper material to be fed in a set direction.

[0021] Through the above technical solution, the feeding drive unit drives the active roller to rotate, causing the roller surface covered with the wear-resistant layer to form a delivery gap with the adjusting roller. The operator drives the adjusting roller to move laterally by tightening the adjusting component, adjusting its distance with the active roller to adapt to the pressing requirements of strips of different thicknesses. After the cut strip enters the gap between the active roller and the adjusting roller, it is clamped by the two rollers rotating in opposite directions and pulled at a constant speed to the next process. This mechanism, through the screw fine adjustment and the cooperation of the wear-resistant roller surface, realizes the delivery gap to quickly adapt to strips of multiple specifications, ensuring that the loose strip after cutting remains flat and without slippage during the delivery process. At the same time, the wear-resistant layer reduces the wear of the roller surface caused by long-term friction, extends the maintenance cycle, and improves the delivery stability and equipment durability.

[0022] During the process of conveying the paper material and the cut paper strips along the set path, multiple feed rollers are set up to continuously rotate and guide the paper.

[0023] Preferably, the frame is further provided with a transmission assembly, the transmission assembly comprising:

[0024] A drive shaft, which is rotatably configured relative to the frame;

[0025] The frame is provided with two bearing seats, which are located on both sides of the frame along the rotation axis of the drive shaft, and the two ends of the drive shaft pass through the bearing seats.

[0026] A transmission gear, which is fixed on the transmission shaft;

[0027] The adjusting roller is provided with a gear one at its axial end, the first cutter roller is provided with a gear two at its axial end, and the second cutter roller is provided with a gear three. The gear three meshes with the gear two, and the transmission gear meshes with the gear one and the gear three respectively.

[0028] Through the above technical solution, the transmission shaft is supported by bearing seats on both sides of the frame. The transmission gear meshes synchronously with gear one at the end of the adjusting roller and gear three of the second cutter roller. At the same time, gear two and gear three of the first cutter roller mesh with each other. During operation, the transmission shaft drives the transmission gear to rotate. The power drives the adjusting roller to rotate through gear one to control the paper tension. At the same time, the meshing linkage between gear three and gear two makes the first and second cutter rollers rotate synchronously to complete the cutting. This ensures that the speed of each roller is strictly matched, reduces the cumulative error of multi-stage transmission, and realizes the dynamic coordination of tension adjustment and cutting action.

[0029] Preferably, the frame is provided with a grid frame, which has a plurality of parallel guide grooves.

[0030] Through the above technical solution, the cut paper strips pass through the guide slots on the grid frame one by one. The guide slots constrain the travel direction of the corresponding paper strips, preventing adjacent paper strips from tangling or shifting, achieving precise separation and directional transmission of the paper strips, reducing the paper strip drifting, overlapping or knotting phenomena commonly seen in free conveying, and ensuring the uniformity of the wiring in the subsequent winding process and the quality of the finished roll.

[0031] Preferably, the frame is provided with an unwinding mechanism, the unwinding mechanism comprising:

[0032] A roll shaft carries a paper roll formed by winding paper material. The roll shaft is equipped with a material fixing assembly, which includes a material fixing cylinder and a material fixing component movably connected to the output end of the material fixing cylinder. The material fixing cylinder drives the material fixing component to press against the inner wall of the paper roll to achieve coaxial fixation between the roll shaft and the paper roll.

[0033] The movable frame is laterally movable on the machine frame. The movable frame is provided with two bearing seats. The rotating shafts at both ends of the drum shaft can be inserted into the two bearing seats to guide the rotation of the drum shaft.

[0034] The feed brake has its output end connected to the rotating shaft via a transmission assembly, and is used to drive the rotating shaft to rotate.

[0035] Through the above technical solution, the roll shaft passes through the through hole of the paper roll. At this time, the two ends of the shaft are guided to rotate by the bearings in the guide seat. The fixed material cylinder pushes the fixed material component to expand radially to press against the inner wall of the roll shaft, realizing the synchronous locking and power transmission of the shaft and the roll shaft. The feeding brake drives the shaft to rotate through the transmission component (such as the gear set). The movable frame is in the unwinding position. The shaft drives the roll shaft to rotate continuously to release the paper, realizing the quick disassembly and assembly of the roll material and precise coaxial fixation. This avoids the time-consuming and eccentric swing problems of the traditional coil fastening method and ensures continuous and stable material supply in the unwinding process.

[0036] Preferably, the frame is provided with a correction mechanism, which includes:

[0037] First-order inspection item;

[0038] The second direction detection element is symmetrically arranged on both sides of the frame along the paper material travel path with the first direction detection element, so that the two sides of the paper material pass through the detection ports between the first direction detection element and the second direction detection element.

[0039] The correction drive is connected to the movable frame. When the first or second detection element detects that the paper material deviates from the set position, the correction drive drives the movable frame to move laterally to change the output path of the paper material.

[0040] Through the above technical solution, when the paper material deviates laterally during its movement, the detection device on the deviated side triggers a signal, and the correction drive immediately drives the movable frame to slide laterally along the frame, causing the entire roll shaft to move slightly to correct the paper material output path, so that the paper material returns to the center position in real time. Through the closed-loop control with dual detection device dynamic monitoring and movable frame linkage correction, online automatic correction of the paper material during the unwinding process is realized, effectively eliminating the problem of paper material deviation before cutting caused by roll eccentricity, tension fluctuation or mechanical error, ensuring the consistency of the cut strip width and the accuracy of the winding alignment, and reducing the frequency of manual intervention and material loss.

[0041] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0042] 1. This technical solution achieves stepless and precise adjustment of the gap between the cutter rollers through the linkage design of the threaded adjustment rod and the cutter roller, controls the cutting pressure and channel size, ensures the uniformity of the cutting accuracy, improves the adaptability and adjustment efficiency of the equipment to paper materials of different thicknesses, and reduces the maintenance costs caused by the complex structure.

[0043] 2. This technical solution uses dual detection components to dynamically monitor paper material deviation, and the correction drive component drives the movable frame to move laterally, correcting the position of the roll shaft in real time. This suppresses deviation problems caused by roll material eccentricity or mechanical errors, ensuring consistent cutting width and precise rewinding alignment, reducing the frequency of manual adjustments and material waste.

[0044] 3. This technical solution uses a transmission component in the frame. Through the synchronous meshing design of transmission gears, gear one, gear two and gear three, the adjusting roller and the double blade roller are linked. Under single-axis drive, the tension control and cutting action are coordinated in real time, reducing multi-stage transmission errors and ensuring precise matching of the speed of each roller. This improves the cutting accuracy and enhances the stability of equipment operation. Attached Figure Description

[0050] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0051] Example:

[0052] See Figure 1 A cutting device for a cutting and winding machine includes a frame 1, on which a cutting mechanism 2 is provided. The cutting mechanism 2 includes a first cutter roller 21, a second cutter roller 22, and a strip cutting drive 23. The first cutter roller 21 and the second cutter roller 22 are distributed opposite each other on the upper and lower sides. Both cutter rollers are rotatably connected to the frame 1, and their rotation axes are parallel to each other. Paper can pass between the two cutter rollers. The surface of the first cutter roller 21 is provided with a plurality of annular blades 4 arranged equidistantly along the axial direction. The surface of the second cutter roller 2242 that cooperates with it is provided with annular guide grooves adapted to the annular blades 4. The groove width is greater than the thickness of the blades. Each annular blade 4 is fitted into each annular cutter groove 5 in a one-to-one correspondence. The strip cutting drive 23 is installed on the frame 1, and its output end is connected to the first cutter roller 21 and drives the first cutter roller 21 to rotate. When the paper passes through the cutting area between the two cutter rollers, the annular blades 4 continuously cut the paper into strips of equal width corresponding to the blade spacing.

[0053] The frame 1 is equipped with a pressing adjustment assembly 3, which includes an adjustment frame 31, an adjustment seat 32, and an adjustment rod 33. The adjustment frame 31 includes two parts, with two adjustment frames 31 located on opposite sides of the frame 1 along the rotation axis of the first cutter roller 21. Each adjustment frame 31 is slidably connected to the adjustment seat 32, and its sliding direction is set vertically. Each side of the adjustment seat 32 is threadedly connected to the adjustment rod 33. By operating the adjustment rod 33 to rotate in different directions, the adjustment seat 32 is driven to slide upward or downward, thereby driving the first cutter roller 21 to move closer to or further away from the second cutter roller 22, adjusting the gap between the two or the degree of pressing on the paper material, which is suitable for paper materials of different thicknesses.

[0054] The frame 1 is also equipped with a guide mechanism 6, which is located on the discharge side of the cutting mechanism 2. It includes a drive roller 61 and an adjusting roller 62. Two adjusting rollers 62 are provided, each with a wear-resistant layer on its surface. The adjusting rollers 62 are rotatably connected to the frame 1 via bearing seats 82, and their rotation axes are parallel to the rotation axis of the second cutter roller 22. The two adjusting rollers 62 are connected by a transmission belt fitted on the same end to ensure synchronous rotation. The drive roller 6151 is arranged above the spaced position between the two adjusting rollers 62, and is rotatably set relative to the frame 1, with its rotation axis parallel to that of the adjusting rollers 6151. 2. Parallel; The frame 1 is provided with a pressure regulating assembly 63, which has two components. Each pressure regulating assembly 63 includes a pressure regulating frame 631 and a pressure regulating rod 632. The two pressure regulating frames 631 are respectively fixed on opposite sides of the frame 1 along the paper strip feeding direction. The upper part of each pressure regulating rod 632 is threadedly connected to the pressure regulating frame 631, and the lower part is threadedly connected to the end of the corresponding drive roller 61. By operating the pressure regulating rod 632 to rotate in different directions, the drive roller 61 is driven to rise and fall synchronously to adjust the gap between it and the regulating roller 62, thereby changing the pressure on the paper strip and improving adjustability.

[0055] The frame 1 is equipped with a transmission assembly 8, which is located between the guide mechanism 6 and the cutting mechanism 2. The transmission assembly 8 includes a transmission shaft 81, a bearing seat 82, and a transmission gear 83. The bearing seat 82 includes two parts, which are symmetrically arranged on opposite sides of the frame 1 along the paper feeding direction. The bearing seats 82 on both sides are rotatably connected to the transmission shaft 81 through bearings. The rotation axis of the transmission shaft 81 is parallel to the rotation axis of the adjusting roller 62. The synchronous gear is coaxially fixed to one end of the transmission shaft 81.

[0056] A gear 2 10 is coaxially fixed to the end of the first cutter roller 21, and a gear 3 11 is coaxially fixed to the corresponding end of the second cutter roller 22. The gear 3 11 meshes with the gear 2 10 to form a first-stage transmission. The gear 2 10 meshes with the transmission gear 83 to form a second-stage transmission. A gear 1 9 is provided at the corresponding end of an adjusting roller 62 close to the transmission shaft 81. The gear 1 9 is coaxially fixed with the adjusting roller 62 and meshes with the transmission gear 83 to form a third-stage transmission. Through this three-stage meshing structure, the two adjusting rollers 62, the transmission shaft 81, the first cutter roller 21, and the second cutter roller 22 form a closed-loop synchronous transmission system to ensure that the rotational speeds of each roller are matched.

[0057] The frame 1 is equipped with multiple feed rollers 7, which are arranged at intervals along the length of the frame 1. Multi-roller cooperative feeding is adopted. Each feed roller 7 is connected to the frame body on both sides of the frame 11 through both ends and is rotatably set relative to the frame 1. The rotation axes of each feed roller 7 are parallel to each other. Through the differential speed coordination and spatial phase difference arrangement of the roller array, the paper material is stably fed along a preset angle and direction.

[0058] The frame 1 is equipped with a grid frame 12, which has several parallel guide grooves 13. The groove width is adapted to the width of the paper strip. The several guide grooves 13 correspond one-to-one for the paper strips to pass through, guiding multiple paper strips independently at a preset interval, positioning the paper strips, reducing the occurrence of paper strip entanglement, and improving the stability of feeding.

[0059] The frame 1 is equipped with an unwinding mechanism 15, which includes a roll shaft 151, a movable frame 152, and a feeding brake 153. The mechanism is slidably connected to the frame 1 via pulleys and a slide rail structure, with the sliding direction being transverse. The roll shaft 151 is rotatably mounted on the movable frame 152. The paper material is wound into a paper roll 100. The size and shape of the roll shaft 151 match the shaft hole of the paper roll 100. The preferred material for the paper is kraft paper. The roll shaft 151 passes through the shaft hole. A material-fixing assembly 16 is provided inside the roll shaft 151, which includes a material-fixing air... The cylinder 161 and the fixing component 162 are slidably disposed relative to the roll shaft 151, and the sliding direction is perpendicular to the rotation direction of the roll shaft 151. The roll shaft 151 has a corresponding clearance groove on its outer wall for the fixing component 162 to pass through. The output end of the fixing cylinder 161 is connected to the fixing component 162 and is used to drive the fixing component 162 to move outward. The fixing component 162 can press against the inner side wall of the paper roll 100. At this time, the roll shaft 151 and the paper roll 100 are coaxially fixed, and the paper roll 100 is driven to rotate to smoothly feed out the paper.

[0060] The movable frame 152 is provided with two guide seats 17, which are bolted to the upper end face of the movable frame 152. The guide seats 17 shown in this embodiment all include two parts: a seat body and a seat cover. The seat body and the seat cover are bolted to each other. The drum shaft 151 has a rotating shaft 14, which is set at both ends of the drum shaft 151 along the axial direction. The installation position of the two guide seats 17 is adapted to the rotating shafts 14 at both ends. A bearing is sleeved on each rotating shaft 14. When the seat cover is opened, the guide seats 17 are opened, and the rotating shafts 14 at both ends can be inserted into the two seat bodies one by one. After the seat cover is installed, the bearing guides the rotating shaft 14 to rotate in the guide seat 17 to reduce rotational friction.

[0061] The frame 1 is equipped with a web guiding mechanism 18, which includes a first-direction detection element 181, a second-direction detection element 182, and a web guiding drive element 183. The second-direction detection element 182 and the first-direction detection element 181 are symmetrically arranged on both sides of the frame 1 along the paper material travel path, and are both welded and fixed to the frame 1. The detection ports of the two detection elements face each other, forming an oblique cross monitoring area. The two feed rollers 7 guide the paper material through the space between the first-direction detection element 181 and the second-direction detection element 182, so that the two edges of the paper material pass through the two detection elements. The detection port between the two is connected to the movable frame 152. The position signal of the paper material is detected by the two detection devices. When the detection device on either side detects that the offset of the paper material edge exceeds the set threshold, the control system operates the correction drive 183 to drive the movable frame 152 to move laterally and perform corresponding lateral displacement compensation. The dynamic angle formed by the axis of the roll shaft 151 and the axis of the feed roller 7 is used to adjust the tension distribution of the paper material, thereby realizing real-time correction of the output path.

[0062] The specific work process of this plan is as follows:

[0063] This technical solution uses a cutting drive 23 to drive the first cutter roller 21 to rotate. When the paper material passes through the paper material channel formed by the tangency of the two, it is continuously cut into multiple strips. The adjusting rod 33 of the pressing and adjusting component 3 precisely controls the axial displacement of the first cutter roller 21 through threaded transmission, realizing stepless adjustment of the paper material channel. This replaces the traditional adjustment structure. Only by rotating the adjusting rod 33 can the cutting pressure and channel size be quickly changed, maintaining cutting accuracy and improving the adaptability of paper materials of different thicknesses and the efficiency of equipment maintenance.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of this technical solution. Those skilled in the art should understand that this technical solution is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this technical solution. Various changes and modifications can be made to this technical solution without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed technical solution.
