[0040] Reference Figures 1 to 3 , is an embodiment of the utility model, which proposes an adaptive thickness paper splitter, including: a frame 1, a support plate 2 arranged on the frame 1, a movable frame 3 that is lifted and lowered and horizontally moved on the frame 1, the movable frame 3 is located below the support plate 2, the slitting wheel 4 is arranged to move horizontally relative to the movable frame 3, and the movable baffle 5 is movably arranged on one side of the frame 1 and is located above the support plate 2.

[0041] In this embodiment, the frame 1 is the basic structure of the paper separating machine, which is welded by high-strength steel to ensure the stability and durability of the equipment. The design of the frame 1 takes into account the compactness and operational convenience of the equipment, ensuring that the operator can easily access all key components. The support plate 2 is installed on the top of the frame 1 and is used to carry the paper to be cut. The support plate 2 is made of anti-slip material to prevent the paper from sliding during the cutting process. The moving frame body 3 is arranged on the frame 1 and can move in the vertical and horizontal directions. The vertical movement of the moving frame body 3 is realized by an electric lifting mechanism, ensuring that the cutting wheel 4 can contact papers of different thicknesses. The horizontal movement is realized by precise linear guides and a servo motor, ensuring the positioning accuracy of the cutting wheel 4 on the paper. The cutting wheel 4 is installed on the moving frame body 3 and can move horizontally relative to the moving frame body 3. The cutting wheel 4 is made of high-quality alloy steel and its surface is hardened to ensure sharpness and durability for long-term use. The horizontal movement of the cutting wheel 4 is automatically adjusted by precise sensors and a control system to adapt to papers of different thicknesses and achieve precise cutting. The moving baffle 5 is arranged on one side of the frame 1, above the support plate 2, and is used to limit the lateral movement of the paper and ensure the stability of the paper during the cutting process. The movement of the moving baffle 5 is also driven by a servo motor and its position is automatically adjusted according to the width of the paper. When using this paper separating machine for cutting operations, the operator first places the paper to be cut on the support plate 2 and adjusts the moving baffle 5 to adapt to the width of the paper. Subsequently, the required cutting width and paper thickness are set through the control system. Based on the input parameters, the cutting wheel 4 is automatically adjusted to the upper surface of the paper to ensure that the cutting surface contacts the paper surface. At the same time, the position of the moving baffle 5 is also automatically adjusted to keep the paper stable. Driven by the moving frame body 3, the cutting wheel 4 moves along the set trajectory to complete the cutting of the paper. By automatically adjusting the positions of the cutting wheel 4 and the moving baffle 5, papers of different thicknesses and widths can be processed efficiently and precisely, improving the efficiency and accuracy of the cutting operation and reducing the labor intensity of the operator.

[0042] Further, it further includes: a shaft body 6, the shaft body 6 is arranged on the moving frame body 3, the cutting wheel 4 is arranged to move along the axial direction of the shaft body 6, a lifting member 7 is arranged to be lifted on the frame 1, and there are two lifting members 7, which are respectively located outside both ends of the shaft body 6 and are used to press the cardboard to be cut.

[0043] In this embodiment, the shaft body 6 is installed on the moving frame body 3, and the slitting wheel 4 is arranged to move axially along the shaft body 6. The introduction of the shaft body 6 ensures the linearity and stability of the slitting wheel 4 during the movement, avoids the shaking of the slitting wheel 4 during high-speed operation, and improves the cutting accuracy. The shaft body 6 adopts a high-precision linear guide rail to ensure the smooth movement of the slitting wheel 4 in the axial direction, reducing friction and wear. There are two lifting members 7, which are respectively located outside the two ends of the shaft body 6 and are designed to press the cardboard to be cut. The lifting movement of the lifting member 7 is controlled by a precise electric actuator, which can automatically adjust the pressing force according to the thickness of the paper to ensure the stability of the paper during slitting and avoid cutting errors caused by paper shaking or deviation. The surface of the lifting member 7 is covered with a soft material, such as rubber or foam, to avoid damaging the paper during pressing. Before the slitting operation starts, the operator places the paper to be cut on the support plate 2, and the moving baffle 5 automatically adjusts to the width of the paper. Subsequently, the lifting member 7 descends and automatically adjusts the pressing force according to the thickness of the paper to ensure the stability of the paper during slitting. At this time, the control system drives the slitting wheel 4 to move axially along the shaft body 6 according to the preset cutting parameters to complete the cutting action. The linear guide rail of the shaft body 6 ensures the linearity of the slitting wheel 4 during the movement and improves the cutting accuracy. By adding the shaft body 6 and the lifting member 7, not only the stability and cutting accuracy of the equipment are improved, but also its ability to process papers of different thicknesses and sizes is enhanced.

[0044] Furthermore, the machine frame 1 has a number of through grooves 101, and further includes a first clamp 8 and a second clamp 11. The first clamp 8 and the second clamp 11 are movably arranged in the through grooves 101, and the first clamp 8 and the second clamp 11 move closer to or away from each other after moving, for the lateral alignment of the cardboard to be cut.

[0045] In this embodiment, the through groove 101 on the frame 1 is designed to be elongated and perpendicular to the width direction of the cardboard to be cut, ensuring that the first clamp 8 and the second clamp 11 can move freely in the horizontal direction. The number and position of the through grooves 101 are optimized according to the maximum size of the cardboard to be cut and the layout of the equipment to achieve the best alignment effect. Both the first clamp 8 and the second clamp 11 are designed to be structures that can move along the through groove 101, and their movement is driven by a precise electric actuator or pneumatic cylinder to ensure the accuracy and stability of the movement. The front end of the clamp is designed with a soft contact surface, such as a rubber pad, to avoid damaging the paper during the alignment process. In addition, a position sensor is installed on the clamp to detect the real-time position of the clamp for the control system to make precise adjustments. Before the slitting operation starts, the operator places the paper to be cut on the support plate 2. Subsequently, the control system automatically adjusts the positions of the first clamp 8 and the second clamp 11 according to the size information of the paper, making the two approach each other until the clamps gently contact both sides of the paper, achieving precise alignment of the paper in the horizontal direction. During this process, the position sensor continuously monitors the position of the clamp to ensure the alignment accuracy. After the alignment is completed, the slitting wheel 4 starts cutting. Since the paper has been precisely aligned, the cutting accuracy is guaranteed, and the quality of the produced products is more consistent. By introducing the horizontal alignment system, that is, the first clamp 8 and the second clamp 11, precise alignment of the cardboard to be cut in the horizontal direction is achieved, improving the cutting accuracy and production efficiency and reducing the scrap rate.

[0046] Furthermore, it further includes: a swing clamp 10, the swing clamp 10 is swingably and movably arranged in a through groove 101, after the swing clamp 10 swings, it is perpendicular or parallel to the support plate 2, and after the swing clamp 10 moves, it approaches or moves away from the movable baffle 5, for aligning the cardboard to be cut.

[0047] In this embodiment, the swing fixture 10 is made of a lightweight but strong material. One end of it is connected to a fixed point in the through slot 101 through a bearing, allowing it to swing. The other end is designed with a surface that contacts the paper, and this surface is covered with a soft material such as rubber or foam to prevent damage to the paper during the alignment process. The swing range and speed of the swing fixture 10 can be controlled by a motor or a pneumatic cylinder to adapt to different alignment requirements. The through slot 101 on the frame 1 is designed to be long enough to allow the swing fixture 10 to move horizontally within it. The inside of the through slot 101 is equipped with precise guide rails and driving devices such as linear motors or lead screws for controlling the moving speed and position of the swing fixture 10. These driving devices are integrated with the control system to ensure that the swing fixture 10 can accurately move to a predetermined position to achieve alignment with the moving baffle 5. Before the slitting operation starts, the control system automatically adjusts the position and swing angle of the swing fixture 10 according to the size information of the cardboard to be cut. The swing fixture 10 first moves along the through slot 101 to a suitable position and then swings as needed to achieve alignment perpendicular or parallel to the support plate 2. During this process, the moving and swinging actions of the swing fixture 10 are precisely controlled by the control system to ensure that the cardboard to be cut can achieve multi-dimensional precise alignment before slitting, thereby improving the cutting accuracy and production efficiency.

[0048] Furthermore, the first fixture 8 and the second fixture 11 are movably arranged in the through slot 101. The first fixture 8 and the second fixture 11 include a swinging member 801 which is swingably arranged on the frame 1. A gear 802 is arranged on the swinging member 801. There are two racks 803 which are respectively arranged on the first fixture 8 and the second fixture 11. The two racks 803 are arranged oppositely and meshed with the gear 802, and the gear 802 drives the movement of the first fixture 8 and the second fixture 11.

[0049] In this embodiment, a swinging member 801 is mounted on the frame 1. The swinging member 801 is rotated by a motor. After the swinging member 801 swings, the free end of the swinging member 801 swings into or out of the through slot 101. An external drive gear 802 transmits power to a rack 803, thereby driving the movement of the first clamp 8 and the second clamp 11. The gear 802 is fixed to the swinging member 801 and meshes with two oppositely arranged racks 803. The racks 803 are mounted on the first clamp 8 and the second clamp 11, respectively. When the gear 802 rotates, the racks 803 drive the first clamp 8 and the second clamp 11 to achieve synchronous and opposite movement. That is, when one clamp moves inward, the other moves outward, and vice versa, thereby achieving precise alignment of the cardboard to be cut. Before the slitting operation begins, the operator or the control system adjusts the rotation angle of the swinging member 801 according to the size of the cardboard to be cut. When the swing member 801 rotates, the gear 802 rotates accordingly. Through meshing with the rack 803, the first clamp 8 and the second clamp 11 begin to move in opposite directions until the two sides of the cardboard are gently clamped by the two clamps and aligned horizontally. During this process, the gear 802 and rack 803 system ensures the synchronous and precise movement of the two clamps, preventing the cardboard from shifting during alignment and improving the accuracy and consistency of cutting. The introduction of the gear 802 and rack 803 alignment system not only achieves precise and synchronous movement of the first clamp 8 and the second clamp 11, but also simplifies the operation and maintenance of the equipment, improves the alignment accuracy of the cardboard to be cut, and thus enhances cutting quality and production efficiency.

[0050] Furthermore, the first clamp 8 and the second clamp 11 both have a give-way sliding cavity 804, the swinging member 801 has a first guide surface 805 on the side away from the gear 802, the slider 9 is slidably set in the give-way sliding cavity 804, the slider 9 has a second guide surface 901 and a third guide surface 902, the second guide surface 901 abuts against the first guide surface 805, the rack 803 is slidably set in the give-way sliding cavity 804, the upper side of the rack 803 has a fourth guide surface 806, the third guide surface 902 abuts against the fourth guide surface 806, after the swinging member 801 rotates, the first guide surface 805 abuts against the second guide surface 901, pushing the slider 9 to slide, and after the slider 9 slides, it pushes the rack 803 to slide in the length direction perpendicular to the rack 803.

[0051] In this embodiment, both the first fixture 8 and the second fixture 11 have a relief sliding cavity 804 for accommodating the sliding of the slider 9 and the rack 803 to ensure their smooth movement during adjustment. One side of the swing member 801 has a first guiding surface 805. When the swing member 801 is driven to rotate, the first guiding surface 805 contacts the second guiding surface 901 of the slider 9, pushing the slider 9 to slide along the relief sliding cavity 804. The slider 9 is located within the relief sliding cavity 804 and is designed with a second guiding surface 901 and a third guiding surface 902. The second guiding surface 901 abuts against the first guiding surface 805 of the swing member 801, while the third guiding surface 902 contacts the fourth guiding surface 806 of the rack 803. The rack 803 is also slidably arranged within the relief sliding cavity 804 and has a fourth guiding surface 806 on its upper side. When the slider 9 is pushed by the swing member 801 to slide, the contact between the third guiding surface 902 and the fourth guiding surface 806 will push the rack 803 to slide perpendicular to its length direction. When it is necessary to adjust the paper separator to adapt to papers of different thicknesses, the operator can drive the swing member 801 to rotate through an external driving device such as a motor. When the swing member 801 rotates, its first guiding surface 805 will contact the second guiding surface 901 of the slider 9 and push the slider 9 to slide along the relief sliding cavity 804. The sliding of the slider 9 further, through the contact between the third guiding surface 902 and the fourth guiding surface 806 of the rack 803, pushes the rack 803 to slide perpendicular to its length direction. This perpendicular sliding of the rack 803 will change the meshing relationship between the rack 803 and the gear 802, so that the paper separator can achieve blanking realized by the first fixture 8 or the second fixture 11. Through the linkage design of the swing member 801, the slider 9 and the rack 803, the paper separator can automatically adapt to papers of different thicknesses without frequent manual adjustment, and also realizes automatic blanking, improving production efficiency and operation convenience. The perpendicular sliding of the rack 803 provides precise thickness adjustment ability, ensuring the stability and accuracy of the paper during the cutting process. The guiding surface design between the slider 9, the swing member 801 and the rack 803 ensures a smooth transition during the blanking adjustment process, reduces mechanical wear, and extends the service life of the equipment. The first guiding surface 805 is an arc-shaped guiding surface that gradually extends along the rotation point at the lower end of the swing member 801 to ensure that the second guiding surface 901 can be gradually pressed when swinging downward. Through the above design, the paper separator with self-adaptive thickness can flexibly meet the cutting requirements of papers of different thicknesses, improving production efficiency and processing accuracy.

[0052] Further, an elastic member 12 is further included. The elastic member 12 is arranged on the frame 1, with one end acting on the frame and the other end acting on the rack 803 to provide the force for the meshing of the rack 803 and the gear 802.

[0053] In this embodiment, when the rack 803 slides vertically under the push of the slider 9, the elastic member 12 will apply a force to the rack 803 in the direction of the gear 802, ensuring that the rack 803 and the gear 802 can achieve the reset engagement of the rack 803 after the swinging member 801 rotates when the blanking is completed. The introduction of the elastic member 12 automatically adjusts the meshing state of the rack 803 and the gear 802 through the elastic member 12, reducing the necessity of manual intervention, simplifying the operation process, and improving the production efficiency. By introducing the elastic member 12 into the paper separating machine with adaptive thickness, the stability and accuracy of the gear 802 - rack 803 alignment system are improved, and the labor intensity of the operator is reduced.

[0054] Furthermore, it further includes a linear driving member 13. The linear driving member 13 is arranged on the frame 1 and is used to drive the moving baffle 5 to move.

[0055] In this embodiment, the coordinated operation of the linear driving member 13 and the rotational driving member enables the paper separating machine to automatically adjust the cutting parameters according to the thickness and width of the paper, improving the flexibility and adaptability of the equipment. The precise displacement control of the linear driving member 13 ensures the accuracy of paper cutting, reduces the cutting error, and improves the finished product quality. The design of the linear driving member 13 reduces manual intervention, improves the production efficiency, and reduces the labor intensity.
