Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] In this embodiment, refer to Figure 1 - Figure 8 The specific implementation of the paper roll cutting equipment includes a frame 1 and a conveying component 2 disposed on the frame 1. One end of the frame 1 is provided with a cutting component 3 that cooperates with the conveying component 2, and one side of the frame 1 is provided with a feeding component 4 that cooperates with the conveying component 2.

[0019] In this embodiment, the conveying assembly 2 consists of a limiting frame 21, a conveyor belt 22, and several rolling rollers 23. The several rolling rollers 23 are evenly distributed along the length direction of the frame 1 through the limiting frame 21. The conveyor belt 22 is sleeved on the outside of the rolling rollers 23 and achieves synchronous operation through friction transmission between the conveyor belt 22 and the rolling rollers 23 by tension.

[0020] The limit frame 21 is provided with a bearing seat for fixing and supporting the rolling roller 23. By setting the bearing seat, it is ensured that the rolling roller 23 can rotate smoothly on the limit frame 21, reducing vibration and deviation during operation and improving the stability of the conveyor belt 22.

[0021] One end of one of the rolling rollers 23 is connected to a drive motor 24. The rotation of the motor drives the transmission roller and the conveyor belt 22 to operate, thereby realizing the continuous conveying of the paper roll on the conveyor belt 22. Both sides of the limiting frame 21 are higher than the upper surface of the conveyor belt 22, forming a lateral limiting structure, which effectively prevents the paper roll from falling off the conveyor belt 22 during the conveying process, ensuring the stability and safety of the conveying process.

[0022] The cutting assembly 3 includes a fixed frame 31 and a drive wheel 32, a driven wheel 33 and a blade belt 34 mounted on the fixed frame 31. An adjustment plate 35 is provided on one side of the fixed frame 31, and the driven wheel 33 is rotatably mounted on the adjustment plate 35.

[0023] The fixed frame 31 is equipped with a drive screw 311 that cooperates with the adjusting plate 35. The drive screw 311 is rotatably mounted on the fixed frame 31 via a support base. The adjusting plate 35 is fixedly equipped with a nut seat 351 that is threadedly connected to the drive screw 311. By rotating the drive screw 311, the adjusting plate 35 can be driven to reciprocate along the height direction of the frame 1, thereby adjusting the distance between the driven wheel 33 and the driving wheel 32, realizing precise adjustment of the tension of the blade belt 34, and ensuring that the blade belt 34 is always in the best working condition during the cutting process.

[0024] One end of the drive screw 311 protrudes from the upper end of the fixed frame 31 and is connected to a handwheel 312. When it is necessary to adjust the tension of the blade belt 34, the drive screw 311 can be rotated by rotating the handwheel 312, which in turn pushes the adjusting plate 35 to move up and down, thereby achieving precise adjustment of the position of the driven wheel 33.

[0025] A rotary motor 36 for driving the drive wheel 32 is provided on one side of the fixed frame 31. The rotary motor 36 is connected to the shaft end of the drive wheel 32 through a coupling. When the rotary motor 36 is started, it drives the drive wheel 32 to rotate, and at the same time, the cutter belt 34 rotates at high speed with the synchronous rotation of the drive wheel 32 and the driven wheel 33, thereby realizing continuous cutting of the paper roll in the conveyor.

[0026] The fixed frame 31 is also equipped with a conveyor belt 37, which is used to smoothly deliver the cut paper roll segments, thereby avoiding the accumulation of cut paper segments in the cutting area and causing blockage or paper jams. The end of the conveyor belt 37 near the cutter belt 34 is equipped with a guide plate. The guide plate is inclined downwards to facilitate the smooth sliding of the cut paper segments onto the conveyor belt 37, so that they can be quickly transported to the next process or receiving area by the conveyor belt 37, ensuring the continuity of the production process.

[0027] Both sides of the cutter belt 34 have cutting edges, enabling it to perform cutting during reciprocating motion, effectively improving cutting efficiency and extending its service life. The alternating operation of the two cutting edges effectively reduces wear on one side, allowing the cutter belt 34 to maintain stable cutting performance over extended periods, reducing replacement frequency and improving overall equipment efficiency.

[0028] A clamping component 5 is provided at one end of the conveying component 2 near the cutting component 3. The frame 1 is provided with a reciprocating sliding plate 7 via a third drive component 6, and both the conveying component 2 and the clamping component 5 are located on the upper end of the sliding plate 7.

[0029] In this embodiment, two clamping components 5 are provided, which are symmetrically arranged on both sides of the blade belt 34 to clamp the paper roll during cutting and prevent the paper from shifting or springing back during the cutting process.

[0030] The clamping assembly 5 includes a bracket 51, a fixing plate 52, a side pressure plate 53, and an upper pressure plate 54. The bracket 51 is mounted on the slide plate 7 via a fourth driving member 55. The side pressure plate 53 is vertically positioned on the side of the bracket 51 closest to the conveyor belt 22. The upper pressure plate 54 is slidably mounted on the bracket 51 via a fifth driving member 56 and moves vertically up and down as driven by the fifth driving member 56, thereby clamping and releasing the paper roll. The fixing plate 52 is located on the other side of the conveyor belt 22 and works in conjunction with the side pressure plate 53 to limit the lateral displacement of the paper roll during the cutting process, ensuring a flat cut surface without burrs.

[0031] The lower end of the upper pressure plate 54 is provided with an adjustable fixing block. The fixing block is connected to the upper pressure plate 54 by bolts and can be adjusted in position along the width direction of the conveyor belt 22 to adapt to the cutting requirements of different specifications of paper rolls and ensure that the clamping force is evenly distributed on the surface of the paper roll.

[0032] The upper end of the frame 1 is provided with several slide rails 12, and the lower end of the slide plate 7 is provided with several sliders 71 that cooperate with the slide rails 12. Through the cooperation of the slide rails 12 and the sliders 71, the slide plate 7 and the conveying component 2 and clamping component 5 on the slide plate 7 can slide smoothly along the width direction of the frame 1, thereby cooperating with the cutting component 3 to complete the precise cutting and efficient conveying of the paper roll.

[0033] The output end of the third drive unit 6 is provided with a crank rod 61 that cooperates with the slide plate 7, and the slide plate 7 is provided with a sliding groove 72 that cooperates with the crank rod 61. By setting the sliding groove 72, the rotational motion of the crank rod 61 is converted into the reciprocating linear motion of the slide plate 7, thereby driving the clamping assembly 5 and the conveying assembly 2 to move back and forth in the cutting area, so that the paper roll contacts the blade belt 34 and achieves continuous cutting.

[0034] In use, the paper roll is pushed onto the feeding belt by the feeding assembly 4, and driven by the drive motor 24, the paper roll is conveyed forward along the feeding belt until it reaches the cutting area. When the front end of the paper roll reaches the cutting position, the bracket 51, under the action of the fourth drive member 55, drives the side pressure plate 53 to cooperate with the fixing plate 52 to clamp the paper roll, and the fifth drive member 56 drives the upper pressure plate 54 to move down, so that the fixing block presses the surface of the paper roll to ensure stability during cutting and complete the clamping action of the paper roll.

[0035] Subsequently, the rotary motor 36 and the third drive unit 6 are started. The rotary motor 36 drives the blade belt 34 to rotate at high speed. At the same time, the third drive unit 6 pushes the slide plate 7 to reciprocate through the crank rod 61, so that the paper roll and the blade belt 34 generate relative motion, thereby completing the cutting action.

[0036] After a cut is completed, the third drive unit 6 pauses its operation, positioning the paper roll on one side of the cutter belt 34. The fourth drive unit 55 and the fifth drive unit 56 then control the side pressure plate 53 and the upper pressure plate 54 to reset, releasing the cut paper. Subsequently, the conveyor belt 22 pushes the paper roll forward, delivering the next section to be cut to the cutting area, and repeats the clamping and cutting actions to ensure that each section of paper is of precisely consistent length.

[0037] In addition, while the conveyor belt 22 pushes the paper roll forward, it can push the cut paper roll segments onto the conveyor belt 37, which then transports them to the next station for stacking or packaging, thereby avoiding the accumulation of cut paper in the cutting area and ensuring continuous cutting operations.

[0038] The feeding assembly 4 includes a guide plate 41, a limiting plate 42, and a pusher plate 43. The guide plate 41 is located on one side of the frame 1. The limiting plate 42 is swung and installed on one end of the guide plate 41 near the conveying assembly 2 by a first driving member 44. The pusher plate 43 slides up and down on the other end of the guide plate 41 by a second driving member 45.

[0039] The pusher plate 43 reciprocates linearly on the frame 1 via the second drive component 45. When the pusher plate 43 is at its lowest point, it is flush with the discharge end of the previous process, thus facilitating the reception of the roll of paper pushed from the previous process and smoothly pushing it onto the guide plate 41. When the pusher plate 43 moves upward, it pushes the roll of paper along the guide plate 41 above the feeding belt. A baffle is fixedly installed on one side of the pusher plate 43, and the length of the baffle is greater than the moving distance of the pusher plate 43. This ensures that the paper roll pushed by the previous process will not get stuck in the gap created by the rise of the pusher plate 43, thus avoiding problems such as the pusher plate 43 failing to return to its original position. The guide plate 41 is inclined to facilitate the smooth sliding of the paper roll into the feed belt under the push of the pusher plate 43. Both the guide plate 41 and the pusher plate 43 are inclined toward the conveying assembly 2. The inclined design allows the paper roll to slide naturally toward the conveying assembly 2 under the action of gravity when it is on the guide plate 41 and the pusher plate 43, thereby completing the automatic guidance toward the conveying assembly 2, reducing pushing resistance and improving feeding efficiency.

[0040] In this embodiment, the limiting plate 42 is rotatably mounted on the guide plate 41 near the conveying assembly 2 via a rotating shaft 421, and is provided with a swing arm 422 that cooperates with the first driving member 44. The swing arm 422 is connected to the output end of the first driving member 44 via a connecting rod, so that it swings along the rotating shaft 421 under the drive of the first driving member 44, thereby realizing the angle adjustment of the limiting plate 42 and playing a limiting or releasing role.

[0041] The angle between the limiting plate 42 and the guide plate 41 is 90-180 degrees. When the roll of paper on the conveyor belt 22 is not completely cut, the limiting plate 42 is in a limiting state, forming a 90-degree angle with the guide plate 41, preventing the roll of paper on the guide plate 41 from sliding into the area of ​​the conveyor belt 22, thus avoiding interference with the current cutting operation; after the section of paper is cut and conveyed away, the first driving component 44 drives the swing arm 422 to move, causing the limiting plate 42 to rotate to a state of 180 degrees parallel with the guide plate 41, releasing the limiting position. At this time, since the roll of paper on the guide plate 41 is no longer obstructed, it automatically slides along the inclined guide plate 41 towards the feeding belt under the action of gravity, completing the feeding process.

[0042] By repeatedly executing the swinging motion of the limit plate 42 and the lifting motion of the pusher plate 43 in coordination, rhythmic intermittent feeding is achieved, ensuring that each section of paper roll is sent into the cutting area only after the previous section has been cut, avoiding the accumulation or interference of the roll material, and ensuring the continuity and stability of the cutting operation.

[0043] The swing arm 422 is tilted outward from one end of the limiting plate 42. This outward tilt design allows the limiting plate 42 to move more smoothly during rotation, preventing interference between the connecting rod and the frame 1 or other components, while ensuring stable and reliable swinging. Simultaneously, the tilted arrangement of the swing arm 422 allows the first drive component 44 to be installed more compactly at the lower end of the guide plate 41, avoiding spatial conflicts with the conveying assembly 2 and further optimizing the overall equipment layout.

[0044] The pusher plate 43 is equipped with a guide rod 46, and the frame 1 is equipped with a guide sleeve 11 that cooperates with the guide rod 46. Through the cooperation of the guide rod 46 and the guide sleeve 11, the pusher plate 43 maintains a stable linear motion during the lifting process, ensuring that the pusher plate 43 will not deflect or jam when moving up and down, effectively improving the running accuracy and service life.

[0045] In this embodiment, three pusher plates 43 and two driving components 45 are spaced apart. The three pusher plates 43 are evenly distributed along the length of the guide plate 41 and are independently driven by the three second driving components 45. Through the coordinated control of the three second driving components 45, the three pusher plates 43 are raised and lowered synchronously, ensuring the consistency and stability of the pushing action while providing sufficient thrust to smoothly push paper rolls of different lengths. This ensures that paper rolls of different specifications can be reliably conveyed during the feeding process, avoiding paper rolls not being pushed in place or jamming due to insufficient thrust.

[0046] Both the first drive component 44 and the second drive component 45 can be pneumatic cylinders, hydraulic cylinders, or electric actuators. The appropriate type should be selected based on the actual installation space and control precision requirements. In this embodiment, pneumatic cylinders are used as the drive element, achieving rapid response and precise control while simplifying the equipment structure and reducing maintenance costs. This, in turn, reduces the overall operating cost of the equipment and improves system reliability.

[0047] The third drive component 6 uses a stepper motor or servo motor. The stepper motor or servo motor enables precise angle control of the crank lever 61, ensuring that the cutter belt 34 is in a clearance position during the feeding process. This avoids interference with the pusher plate 43 or the paper roll, preventing the risk of collision between the cutter belt 34 and the material, and ensuring safe and smooth feeding. This, in turn, improves the stability of the feeding process and the safety of equipment operation.

[0048] The beneficial effects of this utility model are as follows: Through the cooperation of the pusher plate 43 and the second drive member 45, the finished paper roll is pushed upward to the guide plate 41. And through the cooperation of the guide plate 41, the limiting plate 42 and the first drive member 44, the paper roll is limited and released, and the paper rolls are fed into the conveying assembly 2 one by one, thereby realizing automatic continuous feeding, reducing manual intervention, reducing the risk of wrinkles and contamination of the paper rolls during the handling process, and improving production efficiency and product quality.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
