Description

Technical Field

[0001] This utility model relates to the field of paperboard production equipment technology, and in particular to a waste paperboard transfer and slitting mechanism. Background Technology

[0002] Currently, on the production line, incoming rolls of raw paper need to be cut to pre-set dimensions to provide standardized cardboard for subsequent product processing. During cutting, it's inevitable that the cut waste cardboard needs to be transported off-line for unified sorting and recycling. Currently, the cut waste cardboard is directly transported to waste bins for collection. However, some of the cut waste cardboard is quite large, while the waste bins have limited openings. When the waste cardboard falls directly into the bins, it's irregularly stacked, loose, and messy. This requires manual reorganization to store a significant amount of waste, which is time-consuming and labor-intensive. Therefore, improvements are needed. Utility Model Content

[0003] Therefore, it is necessary to provide a waste paperboard transfer and slitting mechanism to address the above problems.

[0004] A waste cardboard transfer and slitting mechanism includes a frame, a lifting assembly, a conveying assembly, and a slitting assembly. The lifting assembly is installed inside the frame, and its output end is connected to the conveying assembly, driving the conveying assembly to move vertically. The conveying assembly includes a rotating shaft, a drive motor, several conveyor belts, a mounting frame, driven wheels, and a driving wheel. The drive motor is mounted below the mounting frame. Several slots are spaced apart above the mounting frame. Two driven wheels and a driving wheel are linearly and movably arranged in the slots. The driving wheel is positioned between two driven wheels. The conveyor belts are movably sleeved around the driving wheel and driven wheels. The rotating shaft passes through several driving wheels in sequence. The output end of the drive motor is movably connected to the rotating shaft via a belt. The slitting assembly is mounted on the mounting frame and located between two slots.

[0005] Preferably, the slitting assembly includes a saw blade and a protective cover. A rotary motor is installed inside the protective cover. The saw blade is movably mounted inside the protective cover via a pin. A portion of the saw blade protrudes from the top of the protective cover. The output end of the rotary motor is movably connected to the pin, driving the saw blade to rotate inside the protective cover.

[0006] Preferably, it also includes a pressure roller assembly, which includes a support frame and a pressure roller body. The support frame is installed on the outside of the mounting frame, and the two ends of the pressure roller body are movably connected to the support frame. The pressure roller body is located above the conveyor belt.

[0007] Preferably, the lifting assembly includes a hydraulic cylinder and a scissor lift, which are installed inside the frame. The output end of the hydraulic cylinder faces upward and is connected to the scissor lift to drive it to extend and retract. The mounting bracket is installed on the upper end of the scissor lift.

Many specific details are set forth in the following description to provide a full understanding of this utility model.

[0015] like Figures 1-3As shown, a waste cardboard transfer and slitting mechanism includes a frame 1, a lifting assembly 2, a conveying assembly 3, and a slitting assembly 4. The lifting assembly 2 is installed inside the frame 1, and its output end is connected to the conveying assembly 3, driving the conveying assembly 3 to move vertically. The conveying assembly 3 includes a rotating shaft 31, a drive motor 32, several conveyor belts 33, a mounting frame 34, driven wheels 35, and driving wheels 36. The drive motor 32 is mounted below the mounting frame 34. Several slots 341 are spaced apart above the mounting frame 34. Two driven wheels 35 and the driving wheel 36 are linearly and movably arranged in the slots 341. The driving wheel 36 is located between the two driven wheels 35. The conveyor belts 33 are movably sleeved around the driving wheel 36 and the driven wheels 35. The rotating shaft 31 passes through several driving wheels 36 in sequence. The output end of the drive motor 32 is movably connected to the rotating shaft 31 via a belt. The slitting assembly 4 is mounted on the mounting frame 34 and located between two slots 341. Specifically, in this embodiment, the entire mechanism is connected between the end of the production line and the waste paper bin, and is used for the sorting and transfer of waste paperboard cut from the production line. When the waste paperboard enters the conveyor assembly 3, the drive motor 32 starts and drives the rotating shaft 31 to rotate via the belt. The rotating shaft 31 passes through several drive wheels 36 in sequence, so it can drive several drive wheels 36 to rotate synchronously. The driven wheel 35 is movably connected to the drive wheels 36 via the conveyor belt 33. When the drive wheel 36 rotates, the conveyor belt 33 can rotate with the cooperation of the driven wheel 35 and the drive wheel 36, thereby completing the conveying of the paperboard. Initially, the horizontal height of conveyor belt 33 is the same as the production line height. When waste cardboard enters the conveyor assembly 3 from the production line, it continues to be transported by conveyor belt 33. While transporting on conveyor belt 33, the waste cardboard passes through the slitting assembly 4 and is cut in half, thus cutting larger pieces of waste cardboard into smaller pieces. Simultaneously, during the transition and cutting process, lifting assembly 2 lowers the height of conveyor assembly 3 to match the opening of the wastepaper basket, preventing waste cardboard from spilling out. After the waste cardboard leaves conveyor belt 33, lifting assembly 2 resets the conveyor assembly 3, making the horizontal height of conveyor belt 33 level with the production line height again, facilitating the transfer of another piece of waste cardboard. This process is repeated, cutting larger pieces of waste cardboard into smaller pieces for easier collection. This prevents large pieces of waste cardboard from being stored tilted in the wastepaper basket, avoiding the need for re-sorting, saving manpower, and reducing labor costs.

[0016] like Figures 1-2As shown, the slitting assembly 4 includes a saw blade 41 and a protective cover 42. A rotary motor is installed inside the protective cover 42. The saw blade 41 is movably mounted inside the protective cover 42 via a pin. A portion of the saw blade 41 protrudes from the top of the protective cover 42. The output end of the rotary motor is movably connected to the pin, driving the saw blade 41 to rotate within the protective cover 42. Specifically, the protective cover 42 is constructed from welded steel plates, resulting in low cost and high structural strength. The upper surface of the protective cover 42 is flush with the conveyor belt 33, assisting the conveyor belt 33 in supporting waste cardboard. The protective cover 42 also protects the internal rotary motor. The saw blade 41 protrudes from the top of the protective cover 42. When the rotary motor drives the saw blade 41 to rotate, it cuts the waste cardboard transported by the conveyor belt 33 into two sections, preventing the waste cardboard from becoming too large and reducing the difficulty of sorting and organizing the waste cardboard.

[0017] like Figures 1-2 As shown, it also includes a pressure roller assembly 5, which includes a support frame 51 and a pressure roller body 52. ​​The support frame 51 is mounted on the outside of the mounting frame 34, and the two ends of the pressure roller body 52 are movably connected to the support frame 51. The pressure roller body 52 is located above the conveyor belt 33. Specifically, the pressure roller body 52 is placed horizontally on the conveyor belt 33, and the distance between them is adjustable. Specifically, the height of the pressure roller body 52 can be adjusted by means of a cylinder or spring buffer. The pressure roller body 42 and the support frame 41 are movably connected by bearings, so the pressure roller body 42 is rotatable. When the waste paperboard passes between the pressure roller body 42 and the conveyor belt 33, the pressure roller body 42 is subjected to a frictional force from the waste paperboard and rotates. At the same time, it cooperates with the conveyor belt 33 to clamp the waste paperboard, preventing wider waste paperboards from being completely cut when cut by the slitting assembly 4 because they are not under force.

[0018] like Figures 1-3 As shown, the lifting assembly 2 includes a hydraulic cylinder 21 and a scissor lift 22, which are installed inside the frame 1. The output end of the hydraulic cylinder 21 faces upward and is connected to the scissor lift 22, causing it to extend and retract. The mounting frame 34 is installed on the upper end of the scissor lift 22. Specifically, the movement flow of the lifting assembly 2 is as follows: when the output end of the hydraulic cylinder 21 extends, it causes the scissor lift 22 to extend, thereby causing the overall height of the mounting frame 34 to rise. When the output end of the hydraulic cylinder 21 retracts, it causes the scissor lift 22 to retract, causing the overall height of the mounting frame 34 to drop, thus enabling the conveyor belt 33 to adapt to production lines and wastepaper baskets of different heights.

[0019] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
