Description

Technical Field

[0001] This utility model relates to the field of slitting mechanisms, specifically to a slitting mechanism for pearlescent paper. Background Technology

[0002] Pearlescent paper, with its unique luster and texture, is widely used in high-end brochures, books, exquisite packaging, boxes, greeting cards, and hang tags. The composition of pearlescent paper is the same as ordinary white cardboard, consisting of a base layer of fibers, fillers, and a surface coating. However, unlike ordinary white cardboard, its surface coating contains particles that create the pearlescent effect. These particles are composed of titanium dioxide (or other metal oxides) and mica particles, with the mica particles encapsulated by titanium dioxide (or other metal oxides). This structure is flake-like. After printing, pearlescent paper needs to be cut using a slitting machine. A slitting machine is typically used for this process.

[0003] Paper slitting mechanisms are essential equipment in the printing technology field, widely used for slitting paper, film, and other materials. These mechanisms use precise cutting processes to cut paper into required sizes to meet the needs of various industries for paper dimensions and specifications. The basic structure of a paper slitting mechanism typically includes a frame, transmission device, and cutting blades. These components work together to ensure the stability and accuracy of the paper slitting process.

[0004] A prior art slitting machine for pearlescent paper production includes a worktable. Mounting plates are fixedly connected to both sides of the top of the worktable. Two rotating shafts are arranged parallel to each other on the inner side plates of the mounting plates. Each rotating shaft passes through one of the mounting plates. Meshing gears are fixedly connected to one end of each rotating shaft on the outer side of the mounting plate. A swing arm is fixedly connected to one of the rotating shafts between the gear and the mounting plate. A hydraulic cylinder is rotatably connected to the outer side of one of the mounting plates. The telescopic rod of the hydraulic cylinder is rotatably connected to the end of the swing arm away from the rotating shaft. Mounting frames are symmetrically mounted on the outer circumference of the inner side of the rotating shaft on the mounting plate. The mounting frames are equipped with industrial brushes, which reduce dust adhesion to the cutter and further improve the cutting effect.

[0005] However, although existing paper slitting mechanisms play an important role in the paper processing industry, they still have some drawbacks. Existing paper slitting mechanisms may generate dust during the slitting process. Since the pearlescent particles in pearlescent paper are easily broken, dust is easily generated during the slitting process. This dust not only affects the printing effect of the product, but may also damage the equipment. Existing technology reduces the adhesion of dust to the cutting blade by using strip brushes, but the dust tends to accumulate in the cutting area, thereby affecting the cutting of the blade. Moreover, the dust is prone to scattering everywhere, thus affecting the workshop environment. Therefore, effective measures need to be taken to prevent dust scattering. Utility Model Content

[0006] The purpose of this utility model is to solve the above-mentioned defects and provide a slitting mechanism for pearlescent paper, so as to solve the technical problem in the prior art that the pearlescent particles generated by the slitting of existing pearlescent paper are easily scattered everywhere, thereby affecting the printing effect of the product and the workshop environment, and also affecting the stable use of the slitting mechanism.

[0007] The objective of this utility model is achieved through the following means:

[0008] A slitting mechanism for pearlescent paper includes a support frame, a support plate on the top of the support frame, a connecting plate, an upper cutting blade, and a lower cutting plate on the support plate. The upper cutting blade is connected to the connecting plate by bolts. The lower cutting plate is mounted on the support plate, and its surface has a cutting groove that matches the blade edge of the upper cutting blade. The support plate has two sets of symmetrically distributed mounting seats, and a guide groove is formed on the inner side of each mounting seat. A lifting guide plate that can be raised and lowered is connected to the guide groove. A transmission component is provided in the support frame to drive the lifting guide plate to move up and down along the guide groove. The upper cutting blade is connected to the lifting guide plate through the connecting plate. A drive component for providing power to the transmission component is connected to the side of the support frame. A through hole is opened on the lower cutting plate. A chip discharge hole matching the through hole is opened on the support plate. A dust collection hood for covering the chip discharge hole is provided at the bottom of the support plate. A fan is connected to the bottom of the dust collection hood through a negative pressure pipe. A dust collection box is provided on the support frame.

[0009] Furthermore, as described above, the transmission assembly includes a rotating shaft, a cam, and a bearing housing. Both ends of the rotating shaft are connected to the support frame via the bearing housing. One end of the rotating shaft is connected to one end of the lifting guide plate via the cam. The other end of the rotating shaft passes through the support frame and is connected to the drive component.

[0010] The rotation of the rotating shaft drives the cam to rotate, which in turn drives the lifting guide plate to move up and down along the guide groove. The lifting guide plate can then drive the upper cutting blade to descend for cutting and reset. This lifting cutting method can improve the cutting efficiency of pearlescent paper. At the same time, compared with sliding cutting, the lifting cutting method can reduce the dispersion of dust.

[0011] Furthermore, as described above, one end of the cam is coaxially connected to the rotating shaft, and the other end of the cam is hinged to the lifting guide plate via a connector.

[0012] The cam has a raised connecting part, which connects the connecting part to the connecting part. Specifically, the two sides of the cam are connected to the rotating shaft through tension sleeves. When the cam rotates under the drive of the rotating shaft, the connecting part can drive the lifting guide plate to move along the guide groove. The limiting effect of the guide groove makes the lifting guide plate move up and down.

[0013] Furthermore, as described above, the driving component is mounted on one side of the support frame. The driving component includes a reducer and a drive motor. The output end of the reducer is connected to one end of the rotating shaft, and the output shaft of the drive motor is connected to the input end of the reducer.

[0014] Furthermore, as described above, a mounting plate is connected to the side of the mounting base, and an electrostatic eliminator is provided on the mounting plate, with the radial end of the electrostatic eliminator extending downward through the cutting plate.

[0015] Specifically, the slitting mechanism is set in the unwinding device, and the electrostatic eliminator is a radioactive isotope electrostatic eliminator (Po-210α source, activity 18.5 MBq). When the pearlescent paper is unwound by the external unwinding device, the slitting mechanism cuts the pearlescent paper that has been unwound to the set length. The electrostatic eliminator reduces the paper surface potential to within ±50V, reducing the electrostatic adsorption effect, thereby reducing the adhesion of pearlescent particle dust generated during cutting to the paper surface.

[0016] Furthermore, as described above, the negative pressure adsorption air inlet of the fan is connected to a negative pressure pipeline, and the air outlet of the fan extends into the interior of the dust collection box.

[0017] Driven by a fan, the dust collection hood generates negative pressure suction, thereby drawing the cutting powder into the dust collection box in real time, reducing the dust from spreading and improving the cutting environment and cutting effect.

[0018] Furthermore, as described above, baffles are connected to both sides of the support frame, and a receiving cavity for accommodating the transmission component is formed between the two baffles.

[0019] By placing the transmission components inside the housing cavity, the two baffles further reduce the amount of dust entering the housing cavity and reduce dust adhesion to the transmission components, thereby improving the protection effect and service life of the transmission components.

[0020] The beneficial effects of this utility model are as follows: The guide groove design on the inner side of the mounting base provides a stable sliding path for the lifting guide plate, ensuring the smoothness and accuracy during the cutting process. The drive component can control the transmission assembly to drive the lifting guide plate to move up and down along the guide groove. When the pearlescent paper passes between the upper and lower cutting plates, the lifting guide plate drives the upper cutting blade to perform the cutting operation. The transmission assembly can precisely control the lifting movement of the lifting guide plate, thereby controlling the cutting depth and speed, improving cutting quality and efficiency. The through holes on the lower cutting plate and the chip removal holes on the support plate are designed to reduce the accumulation of dust on the lower cutting plate. The dust collection hood is located below the chip removal holes and is connected to a fan through a negative pressure pipe. It can efficiently collect the dust and debris generated during cutting through negative pressure and collect the dust and debris in the dust collection box through the fan, keeping the working environment clean, reducing dust adhesion to the slitting mechanism, and protecting the health of the operators.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] In this embodiment, refer to Figures 1-5The present invention relates to a slitting mechanism for pearlescent paper, comprising a support frame 1, a support plate 2 on the top of the support frame 1, a connecting plate 3, an upper cutting blade 4, and a lower cutting plate 5 on the support plate 2. The upper cutting blade 4 is connected to the connecting plate 3 by bolts. The lower cutting plate 5 is mounted on the support plate 2, and the surface of the lower cutting plate 5 has cutting grooves 6 that match the blades of the upper cutting blade 4. The support plate 2 has two sets of symmetrically distributed mounting seats 7, and the inner side of the mounting seats 7 has guide grooves 8. A lifting guide plate 9 that can be raised and lowered and slid is connected in the guide grooves 8. The support frame 1 is equipped with a transmission component that can drive the lifting guide plate 9 to move up and down along the guide groove 8. The upper cutting blade 4 is connected to the lifting guide plate 9 through the connecting plate 3. The side of the support frame 1 is connected to a driving component for providing power to the transmission component. The lower cutting plate 5 is provided with a through hole 10. The support plate 2 is provided with a chip discharge hole 11 that matches the through hole 10. The bottom of the support plate 2 is provided with a dust collection hood 12 for covering the chip discharge hole 11. The bottom of the dust collection hood 12 is connected to a fan 13 through a negative pressure pipe 25. The support frame 1 is provided with a dust collection box 14.

[0029] In this embodiment, the upper cutting blade 4 is connected to the connecting plate 3 by bolts, which facilitates quick replacement and adjustment and improves the flexibility of operation. The cutting groove 6 formed on the lower cutting plate 5 is precisely matched with the blade of the upper cutting blade 4 to ensure the cutting accuracy and flatness and reduce errors in the cutting process.

[0030] The transmission assembly includes a rotating shaft 15, a cam 16, and a bearing seat 17. Both ends of the rotating shaft 15 are connected to the support frame 1 through the bearing seat 17. The end of the rotating shaft 15 is connected to one end of the lifting guide plate 9 through the cam 16. One end of the rotating shaft 15 passes through the support frame 1 and is connected to the drive component.

[0031] The rotation of the rotating shaft 15 can drive the cam 16 to rotate, thereby causing the cam 16 to drive the lifting guide plate 9 to move up and down along the guide groove 8. The lifting guide plate 9 can drive the upper cutting blade 4 to descend for cutting and reset. The cutting efficiency of pearlescent paper can be improved by the lifting cutting method. At the same time, the cutting method of lifting can reduce the dust from spreading around compared with sliding cutting.

[0032] The lifting guide plate 9 is connected to the connecting plate 3 and moves up and down through the drive of the transmission component. When the cam 16 drives the lifting guide plate 9 to move downward, the connecting plate 3 and the upper cutting blade 4 move downward, thereby cutting the pearlescent paper.

[0033] One end of the cam 16 is coaxially connected to the rotating shaft 15, and the other end of the cam 16 is hinged to the lifting guide plate 9 via a connector 18. The cam 16 has a protruding connecting portion, allowing the connector 18 to connect to the connecting portion. Specifically, both sides of the cam 16 are connected to the rotating shaft 15 via tension sleeves. When the cam 16 rotates under the drive of the rotating shaft 15, the connecting portion can drive the lifting guide plate 9 to move along the guide groove 8. The limiting effect of the guide groove 8 causes the lifting guide plate 9 to move up and down.

[0034] The drive component is installed on one side of the support frame 1. The drive component includes a reducer 19 and a drive motor 20. The output end of the reducer 19 is connected to one end of the rotating shaft 15, and the output shaft of the drive motor 20 is connected to the input end of the reducer 19.

[0035] The drive unit provides power to the transmission components, ensuring the stable operation of the entire slitting mechanism, while also facilitating automated control and reducing reliance on manual operation.

[0036] The mounting base 7 is connected to a mounting plate 21 on its side. An electrostatic eliminator 22 is provided on the mounting plate 21. The radial end of the electrostatic eliminator 22 extends downward through the cutting plate 5.

[0037] Specifically, the slitting mechanism is set in the unwinding device, and the electrostatic eliminator 22 is a radioactive isotope electrostatic eliminator 22 (Po-210α source, activity 18.5 MBq). When the pearlescent paper is unwound by the external unwinding device, the slitting mechanism cuts the pearlescent paper that has been unwound to the set length. The electrostatic eliminator 22 reduces the surface potential of the paper to within ±50V, thereby reducing the electrostatic adsorption effect and reducing the adhesion of pearlescent dust particles generated during cutting to the surface of the paper.

[0038] The negative pressure adsorption air inlet of the fan 13 is connected to the negative pressure pipe 25, and the air outlet of the fan 13 extends into the dust collection box 14. Driven by the fan 13, the dust collection hood 12 generates negative pressure suction, thereby drawing the powder generated during cutting into the dust collection box 14 in real time, reducing the dispersion of dust and improving the cutting environment and cutting effect.

[0039] The negative pressure adsorption of the blower 13 can effectively promote the discharge of debris generated during the cutting process, avoiding poor cutting or equipment damage caused by debris accumulation.

[0040] Both sides of the support frame 1 are connected to baffles 23, and a receiving cavity 24 for accommodating the transmission component is formed between the two baffles 23. By placing the transmission component in the receiving cavity 24, the two baffles 23 further reduce the amount of dust entering the receiving cavity 24, reduce the amount of dust adhering to the transmission component, and improve the protection effect and service life of the transmission component.

[0041] The surface of the upper cutting blade 4 is coated with a Teflon layer, and the surface of the lower cutting plate 5 is coated with a nano-powder coating.

[0042] Specifically, the fan 13 can be a high-pressure fan 13, a vacuum pump, or a blower 13.

[0043] The specific cutting process of the slitting mechanism in this embodiment is as follows:

[0044] The slitting mechanism is placed between the unwinding device and the feeding device. The pearlescent paper is fed to the slitting mechanism through the guide rollers of the unwinding device, so that the pearlescent paper passes between the upper cutting plate and the lower cutting plate 5. When the unwinding reaches the set length, the rotation of the drive motor 20 causes the rotating shaft 15 to drive the cam 16 to rotate. This causes the cam 16 to drive the lifting guide plate 9 to slide down along the guide groove 8 through the connecting piece 18. The lifting guide plate 9 drives the upper cutting blade 4 to move towards the cutting groove 6 through the connecting plate 3, thereby completing the cutting of the pearlescent paper. The transmission component is built into the receiving cavity 24 and baffles 23 are connected to both sides of the support frame 1 to reduce the cutting dust falling into the transmission component and further improve the service life and stability of the transmission component.

[0045] Specifically, when the upper cutting blade 4 is cutting, the static eliminator 22 eliminates static electricity on the pearlescent paper, causing the cutting dust to adhere to the pearlescent paper and the slitting mechanism. At the same time, the fan 13 is started to generate negative pressure suction force, which is delivered to the dust collection hood 12 through the negative pressure pipe 25. Under the action of negative pressure suction, the dust and debris generated during cutting pass through the through hole 10 and the chip discharge hole 11 and fall into the dust collection hood 12. It is then transported into the dust collection box 14 through the negative pressure pipe 25, where the dust and debris are collected. This reduces the accumulation of dust on the lower cutting plate 5, keeps the working environment clean, reduces dust adhesion to the slitting mechanism, and protects the health of the operators.

[0046] 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.
