Technical Field

[0001] This utility model belongs to the field of dust-free paper cutting technology, specifically relating to a dust-free paper cutting structure. Background Technology

[0002] Cleanroom paper is a special material made through dry or wet nonwoven processes. It has high cleanliness, low dust, excellent liquid absorption and mechanical strength, and is widely used in electronics, medical, food packaging and other fields. Cutting is a relatively important process in the production of cleanroom paper. Through cutting, cleanroom paper can be divided into various sizes. Because cleanroom paper has a certain tensile tension, if the flatness of the cleanroom paper is insufficient or it curls upward during the cutting process, uneven cutting pressure will occur, resulting in problems such as rough edges, delamination and dimensional deviations. At the same time, if the cutting blade is tilted, it will also cause the above problems. Utility Model Content

[0019] Please see Figures 1-5 This utility model provides the following technical solution: It includes a base 1, a drive motor 21, an electric telescopic rod 22, and bolts 62. The top of the base 1 is provided with several support rods 11, and the top of each support rod 11 is provided with a horizontal plate 2. The electric telescopic rod 22 is located at the bottom of the horizontal plate 2, and the bottom of the electric telescopic rod 22 is provided with a horizontal rod 3. A cutting blade 31 is detachably connected to the bottom of the horizontal rod 3. The top of the base 1 has a clearance groove 12, which is perpendicularly corresponding to the position of the cutting blade 31. The bottom of the horizontal rod 3 is provided with a connecting plate 4, and the bottom of the connecting plate 4 is provided with a pressure strip 41. The connecting plate 4 and the horizontal rod 3 are connected by a connecting rod 42 and... The fixed block 32 is connected, and the top of the connecting rod 42 is provided with a connecting block 421. The connecting block 421 and the fixed block 32 are connected by a spring 322. Movable plates 5 are slidably connected to the two support rods 11 at both ends of the crossbar 3. The two ends of the cutting blade 31 are detachably connected with positioning components 6. The positioning components 6 include a limiting block 61, a bolt 62, a nut 63 and a positioning rod 64. The limiting block 61, bolt 62, nut 63 and positioning rod 64 are coaxial. A connecting groove 51 is opened on the movable plate 5. The positioning rod 64 is located inside the connecting groove 51. A laser spotlight 52 and an alignment block 53 are respectively provided on the two movable plates 5.

[0020] This implementation includes a base 1, a drive motor 21, an electric telescopic rod 22, and bolts 62. The drive motor 21, electric telescopic rod 22, and bolts 62 are relatively mature existing technologies and will not be described in detail in the specification. The top of the base 1 is provided with several support rods 11, which are perpendicular to and fixedly connected to the base 1. A horizontal plate 2 is provided at the top of each support rod 11, with both ends of the horizontal plate 2 fixedly connected to the tops of two support rods 11. The support rods 11 support the horizontal plate 2. The electric telescopic rod 22 is located at the bottom of the horizontal plate 2, and a horizontal bar 3 is provided at the bottom of the electric telescopic rod 22. The height of the horizontal bar 3 can be adjusted by extending and retracting the electric telescopic rod 22. The horizontal bar 3 is located between two support rods 11 at the same end of the horizontal plate 2. The distance is matched with the width of the crossbar 3. The bottom of the crossbar 3 is detachably connected to a cutting blade 31. When the sharpness of the cutting blade 31 decreases, it can be replaced. The top of the base 1 is provided with a clearance groove 12, which is perpendicular to the position of the cutting blade 31. When the lint-free paper is at the top of the base 1, the cutting blade 31 is lowered to the inside of the clearance groove 12 by the extension and retraction of the electric telescopic rod 22, thus achieving the purpose of cutting the lint-free paper. The bottom of the crossbar 3 is provided with a connecting plate 4, and the bottom of the connecting plate 4 is provided with a pressure strip 41. The pressure strip 41 is fixedly connected to the connecting plate 4, and the connecting plate 4 and the pressure strip 41 are located on one side of the cutting blade 31. The connecting plate 4 and the crossbar 3 are connected by a connecting rod 42 and a fixing block 32. The crossbar 3 is parallel, the connecting rod 42 is perpendicular to the connecting plate 4, and both ends of the connecting plate 4 are provided with connecting rods 42. The connecting rods 42 are fixedly connected to the connecting plate 4. The top of the connecting rod 42 is provided with a connecting block 421, which is fixedly connected to the connecting rod 42. The connecting block 421 and the fixed block 32 are connected by a spring 322. The spring 322 causes the connecting block 421 to be subjected to a downward pulling force. Therefore, when the pressure strip 41 is above the lint-free paper, it will press the lint-free paper, thereby improving the uniformity of force during the cutting of the lint-free paper. Movable plates 5 are slidably connected to the two support rods 11 at both ends of the crossbar 3. The two movable plates 5 are positioned opposite each other. The two ends of the cutting blade 31 are detachably connected with positioning components 6. The two positioning components 6 are connected to the cutting blade 31. The connections are symmetrical. When the cutting blade 31 tilts, there will be a height difference between the two positioning components 6. The positioning component 6 includes a limiting block 61, a bolt 62, a nut 63, and a positioning rod 64. The positioning rod 64 has the same diameter as the bolt 62. The limiting block 61, bolt 62, nut 63, and positioning rod 64 are coaxial and fixedly connected. The nut 63 and bolt 62 are threadedly connected. The movable plate 5 has a connecting groove 51, which is horizontal. The positioning rod 64 is located inside the connecting groove 51, and the connecting groove 51 and positioning rod 64 are at the same height. When the cutting blade 31 moves up and down, the positioning component 6 and the movable plate 5 will move up and down accordingly. When the cutting blade 31 tilts...A height difference exists between the two positioning rods 64, resulting in a height difference between the two movable plates 5. Each movable plate 5 is equipped with a laser spotlight 52 and an alignment block 53. When the two movable plates 5 are at the same height, the laser beam emitted by the laser spotlight 52 illuminates the alignment block 53, indicating that the cutting blade 31 is horizontal. However, when there is a height difference between the two movable plates 5, the alignment block 53 does not receive the laser beam from the laser spotlight 52. This facilitates timely detection of any tilting of the cutting blade 31 and allows for easy calibration of its horizontality.

[0021] The top of the base 1 is provided with several baffles 13, and the distance between two baffles 13 that are opposite each other is less than the length of the cutting blade 31. When the lint-free paper passes over the top of the base 1, the several baffles 13 can guide the lint-free paper and prevent it from shifting during the movement.

[0022] The drive motor 21 is located at the top of the horizontal plate 2, and the horizontal plate 2 is parallel to the base 1; the drive motor 21 can extend and retract the electric telescopic rod 22, thereby achieving the purpose of adjusting the height of the horizontal rod 3.

[0023] The crossbar 3 is parallel to the cross plate 2, and both ends of the crossbar 3 are slidably connected to the two support rods 11. The connection between the crossbar 3 and the support rods 11 can prevent the crossbar 3 from shifting during the lifting and lowering process.

[0024] The fixing block 32 has a through groove 321, and the connecting rod 42 is located inside the through groove 321. The dimensions of the through groove 321 and the connecting rod 42 are matched. The connection between the connecting rod 42 and the through groove 321 allows the distance between the connecting plate 4 and the crossbar 3 to be increased or decreased.

[0025] Both ends of the cutting blade 31 are provided with through holes 311, and the bolt 62 is matched with the size of the through hole 311; when the bolt 62 is located inside the through hole 311, the positioning rod 64 is positioned corresponding to the through hole 311.

[0026] The nut 63 is threadedly connected to the bolt 62, and the width of the connecting groove 51 matches the diameter of the positioning rod 64. By inserting the bolt 62 into the inside of the through hole 311 and then connecting the nut 63 to the bolt 62, the limiting block 61 and the nut 63 are located on both sides of the cutting blade 31, which can fix the position of the positioning rod 64.

[0027] The working principle and usage process of this utility model are as follows: During use, the conveying device positions the lint-free paper at the top of the base 1. Several baffles 13 guide the lint-free paper, preventing it from shifting during movement. The extension and retraction of the electric telescopic rod 22 lowers the cutting blade 31 to the inside of the recess 12, thus achieving the purpose of cutting the lint-free paper. The spring 322 causes the connecting block 421 to experience a downward pulling force. Therefore, when the pressure strip 41 is above the lint-free paper, it presses down on the paper, thereby improving its cutting efficiency. To ensure uniform force distribution during dust-free paper cutting, the connecting groove 51 and the positioning rod 64 are at the same height. When the cutting blade 31 moves up and down, the positioning component 6 and the movable plate 5 will move up and down accordingly. When the cutting blade 31 is tilted, there is a height difference between the two positioning rods 64, which in turn creates a height difference between the two movable plates 5. When the laser beam emitted by the laser spotlight 52 can illuminate the alignment block 53, it indicates that the cutting blade 31 is in a horizontal state. When the alignment block 53 does not receive the laser beam emitted by the laser spotlight 52, it indicates that the cutting blade 31 is in a tilted state.
