Description

Technical Field

[0001] This invention relates to the field of cleanroom paper processing technology, and in particular to a cleanroom paper slitting device with synchronous cleaning. Background Technology

[0002] Cleanroom paper, a functional substrate with low dust residue, high cleanliness, and good liquid absorption, is widely used in fields with stringent environmental cleanliness requirements, such as electronic component manufacturing, pharmaceuticals, and precision instrument cleaning. In the industrial production process of cleanroom paper, to adapt to the processing and application needs of different product specifications and to improve the utilization rate of raw materials, the roll of cleanroom paper needs to be cut longitudinally into multiple narrow rolls of equal width. This longitudinal slitting process is a key step in achieving product diversification and ensuring economical production of cleanroom paper.

[0003] Existing equipment for longitudinal cutting of cleanroom paper has the following technical limitations: First, the equipment lacks sufficient adjustment capability for the cutting interval. The installation and positioning structure of the cutting components is mostly fixed, which can only adapt to a single or a few preset width cutting requirements. When production needs change and the cutting interval needs to be adjusted, the equipment cutting mechanism needs to be disassembled, recalibrated, and reassembled, which is complex and time-consuming. This results in poor adaptability of the equipment to different product specifications, severely restricting production flexibility and specification switching efficiency. Second, the equipment's loading and unloading structure for the raw material paper rollers is poorly designed, lacking convenient positioning and locking mechanisms. The disassembly and installation of the raw material paper rollers requires special tools and multiple auxiliary operation steps, which not only increases the labor intensity of operators but also leads to long paper roller replacement times. Frequent paper roller replacements can easily cause unplanned equipment downtime, significantly reducing overall production efficiency and increasing production time and labor costs. Third, ensuring effective cleaning tools is crucial, as fibers are easily scattered during slitting, polluting the environment. Therefore, this invention proposes a cleanroom paper slitting device with synchronous cleaning to solve the problems existing in the prior art. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a synchronous cleaning dust-free paper slitting device. This device releases the raw paper via paper rollers and rewinds the cut paper via take-up rollers. During cutting, an electric telescopic rod drives the hinged arm to rotate, causing the cutting blades to descend. Cutting is performed as the paper is pulled along. Because multiple sets of moving seats move independently, the position of each set can be changed, thereby changing the position of multiple sets of cutting blades. This allows for easy adjustment of the slitting intervals and spacing according to the cutting needs of the dust-free paper, making it widely applicable.

[0005] To achieve the purpose of this invention, the invention is implemented through the following technical solution: a dust-free paper slitting device for synchronous cleaning, including a support and a paper roller, the paper roller being rotatably disposed at one end of the inner side of the support, and a take-up roller being rotatably disposed at the other end of the inner side of the support, a guide rod and a guide rail being disposed above the middle end of the inner side of the support, and a movable seat being movably disposed on the guide rod and the guide rail, and multiple sets of movable seats being disposed.

[0006] Each set of movable seats moves independently, and one end of the movable seat is provided with a hinged arm that rotates. One end of the hinged arm is provided with a cutting blade that rotates. An electric telescopic rod is hinged to the top of the movable seat, and the output end of the electric telescopic rod is hinged to the hinged arm. A cleaning component is provided in the middle of the lower inner side of the bracket.

[0007] A further improvement is that: the bracket has an ear plate at its middle end, the guide rod and the guide rail are connected to the inner side of the ear plate, and the guide rail has a track groove.

[0008] A further improvement is that a drive wheel is rotatably provided above one end of the interior of the movable seat, and the drive wheel is adapted to the track groove. The drive wheel is driven to rotate by a motor.

[0009] A further improvement is that: a bearing seat is provided at the middle of the top of the movable seat, the electric telescopic rod is hinged to the bearing seat, one end of the movable seat is provided with an ear seat, and the hinge arm is hinged to the ear seat.

[0010] A further improvement is that the cleaning assembly includes a dust hood and a vacuum cleaner, the dust hood being connected to the lower part of the inner side of the ear plate, and a flexible hose connecting the dust hood and the vacuum cleaner.

[0011] A further improvement is that: both sides of one end of the bracket are hinged with clamping arms, and one end of the clamping arm is threaded with a fastening bolt, which is fixedly adapted to one end of the bracket.

[0012] A further improvement is that: a bearing groove is provided at one end of the top of the bracket, the roller shaft of the paper roller is mounted inside the bearing groove, a pressure roller is provided above the inside of the clamping arm, and the pressure roller is used to limit the roller shaft of the paper roller, and a first support wheel is rotatably provided on the bracket at the position below the bearing groove, and the first support wheel is used to support the roller shaft of the paper roller.

[0013] A further improvement is that a drive motor is provided at one end of the outer side of the bracket, and the output end of the drive motor is connected to the take-up roller, and a support component is supported on one side below the take-up roller.

[0014] A further improvement is that the support assembly includes a support base and a top block. The top block is located at both ends of the top of the support base, and a second support wheel is rotatably provided on the inner side of the top block. The second support wheel is used to support one end of the take-up roller. Threaded feet are threadedly installed at the four corners of the bottom of the support base, and the threaded feet are used to adjust the height of the support base.

[0015] A further improvement is that: both ends of the bracket are rotatably provided with guide components, and the guide components include a first guide roller and a second guide roller, the first guide roller and the second guide roller having different heights.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention releases the raw paper through a paper roller and rewinds the cut paper through a winding roller. During cutting, the hinge arm is rotated by an electric telescopic rod, causing the cutting blade to descend. Cutting is performed while the paper is being pulled along. Since multiple sets of moving seats move independently, the position of each set of moving seats can be changed, thereby changing the position of multiple sets of cutting blades. This allows for easy adjustment of the slitting and spacing according to the cutting needs of the dust-free paper, making it widely applicable.

[0018] 2. When replacing the paper roller, this invention only requires releasing the locking bolts, rotating the opening arm, placing the new paper roller shaft into the bearing groove, resetting the opening arm, and locking the bolts. Replacement is convenient and efficient. When it is necessary to remove the paper tube from the winding roller, simply move the support assembly and pull the paper tube out from one end of the winding roller. This is also highly efficient.

[0019] 3. During the cutting process, the present invention uses a vacuum cleaner to provide suction, which is then delivered through a hose to the dust hood to easily absorb any flying fibers and avoid environmental pollution. Attached Figure Description

Detailed Implementation

[0026] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0027] Example 1

[0028] according to Figure 1 , 2 As shown in Figures 3, 4, and 5, this embodiment proposes a dust-free paper slitting device for synchronous cleaning, including a support 1 and a paper roller 2. The paper roller 2 is rotatably disposed at one end of the inner side of the support 1, and a take-up roller 3 is rotatably disposed at the other end of the inner side of the support 1. A guide rod 4 and a guide rail 5 are provided above the middle end of the inner side of the support 1, and a movable seat 6 is movably disposed on the guide rod 4 and the guide rail 5. Multiple sets of movable seats 6 are provided.

[0029] Each set of movable seats 6 moves independently, and one end of each movable seat 6 is rotatably equipped with a hinged arm 7. One end of the hinged arm 7 is rotatably equipped with a cutting blade 8. An electric telescopic rod 9 is hinged to the top of each movable seat 6, and the output end of the electric telescopic rod 9 is hinged to the hinged arm 7. A cleaning component is located in the middle of the lower inner side of the support. In use, the raw paper is released through the paper roller 2, and the cut paper is wound up by the take-up roller 3. During cutting, the electric telescopic rod 9 pushes the hinged arm 7 to rotate, causing the cutting blade 8 to descend. Cutting occurs as the paper is pulled along. Because multiple sets of movable seats 6 move independently, the position of each set of movable seats 6 can be changed, thereby changing the position of multiple sets of cutting blades 8. This allows for easy adjustment of the slitting and spacing according to the cutting needs of the dust-free paper, making it widely applicable.

[0030] The bracket 1 has an ear plate at its middle end. The guide rod 4 and guide rail 5 are connected to the inner side of the ear plate 11. The guide rail 5 has a track groove 12. A drive wheel 10 is rotatably mounted on the upper part of one end of the movable seat 6. The drive wheel 10 is adapted to the track groove 12 and is driven to rotate by a motor 13. In use, the motor 13 drives the drive wheel 10 to rotate, and the drive wheel 10 moves along the track groove 12, changing the position of the movable seat 6 on the guide rod 4. Multiple sets of movable seats 6 can move independently, and the position of each set of movable seats 6 can be changed, thereby changing the position of multiple sets of cutting blades 8. This allows for easy adjustment of the slitting and spacing according to the cutting needs of the dust-free paper, making it widely applicable.

[0031] The movable seat 6 has a bearing seat 14 at the middle of its top, and the electric telescopic rod 9 is hinged to the bearing seat 14 to facilitate the rotation of the electric telescopic rod 9. One end of the movable seat 6 has an ear seat 15, and the hinge arm 7 is hinged to the ear seat 15 to facilitate the rotation of the hinge arm 7.

[0032] The cleaning assembly includes a dust hood 16 and a vacuum cleaner 17. The dust hood 16 is connected to the lower part of the inner side of the ear plate 11, and a hose 18 connects the dust hood 16 and the vacuum cleaner 17. During the cutting process of the cutting blade 8, the vacuum cleaner 17 provides suction, which passes through the hose 18 to the dust hood 16, facilitating the adsorption of splashed fibers and preventing environmental pollution.

[0033] Both sides of one end of the bracket 1 are hinged with clamping arms 19, and one end of the clamping arm 19 is threaded with a fastening bolt 20, which is fixedly fitted to one end of the bracket 1. A bearing groove 21 is provided at one end of the top of the bracket 1. The roller shaft of the paper roller 2 is mounted inside the bearing groove 21. A pressure roller 22 is provided above the inside of the clamping arm 19, and the pressure roller 22 is used to limit the roller shaft of the paper roller 2. A first support roller 23 is rotatably provided on the bracket 1 below the bearing groove 21, and the first support roller 23 is used to support the roller shaft of the paper roller 2. When replacing the paper roller 2, simply release the locking of the fastening bolt 20, rotate to open the clamping arm 19, place the roller shaft of the new paper roller 2 into the bearing groove 21, reset the clamping arm 19, and lock the fastening bolt 20. Replacement is convenient and efficient. The pressure roller 22 limits the roller shaft of the paper roller 2, and the first support roller 23 supports the roller shaft of the paper roller 2, making the installation of the paper roller 2 more stable.

[0034] A drive motor 24 is provided at one end of the outer side of the bracket 1, and the output end of the drive motor 24 is connected to the take-up roller 3. A support assembly is supported on one side below the take-up roller 3. In use, the drive motor 24 drives the take-up roller 3 to rotate and take up the cut paper.

[0035] The support assembly includes a support base 25 and a top block 26. The top block 26 is located at both ends of the top of the support base 25, and a second support wheel 27 is rotatably mounted on the inner side of the top block 26. The second support wheel 27 is used to support one end of the take-up roller 3. Threaded feet 28 are threadedly installed at the four corners of the bottom of the support base 25, and the threaded feet 28 are used to adjust the height of the support base 25. In use, the height of the support base 25 is adjusted by the threaded feet 28 so that the second support wheel 27 supports one end of the take-up roller 3. When it is necessary to remove the paper tube wound on the take-up roller 3, simply adjust the height of the support base 25, move the support assembly, and pull the paper tube out from one end of the take-up roller 3, which is highly efficient.

[0036] Example 2

[0037] according to Figure 1 , 2 As shown in Figures 3, 4, and 5, this embodiment proposes a dust-free paper slitting device for synchronous cleaning, including a support 1 and a paper roller 2. The paper roller 2 is rotatably disposed at one end of the inner side of the support 1, and a take-up roller 3 is rotatably disposed at the other end of the inner side of the support 1. A guide rod 4 and a guide rail 5 are provided above the middle end of the inner side of the support 1, and a movable seat 6 is movably disposed on the guide rod 4 and the guide rail 5. Multiple sets of movable seats 6 are provided.

[0038] Each set of movable seats 6 moves independently, and one end of each movable seat 6 is rotatably equipped with a hinged arm 7. One end of the hinged arm 7 is rotatably equipped with a cutting blade 8. An electric telescopic rod 9 is hinged to the top of each movable seat 6, and the output end of the electric telescopic rod 9 is hinged to the hinged arm 7. A cleaning component is located in the middle of the lower inner side of the support. In use, the raw paper is released through the paper roller 2, and the cut paper is wound up by the take-up roller 3. During cutting, the electric telescopic rod 9 pushes the hinged arm 7 to rotate, causing the cutting blade 8 to descend. Cutting occurs as the paper is pulled along. Because multiple sets of movable seats 6 move independently, the position of each set of movable seats 6 can be changed, thereby changing the position of multiple sets of cutting blades 8. This allows for easy adjustment of the slitting and spacing according to the cutting needs of the dust-free paper, making it widely applicable.

[0039] The movable seat 6 has a bearing seat 14 at the middle of its top, and the electric telescopic rod 9 is hinged to the bearing seat 14 to facilitate the rotation of the electric telescopic rod 9. One end of the movable seat 6 has an ear seat 15, and the hinge arm 7 is hinged to the ear seat 15 to facilitate the rotation of the hinge arm 7.

[0040] The bracket 1 has rotatable guide components at both ends inside, and the guide components include a first guide roller 29 and a second guide roller 30, which are at different heights. During the process of the paper roller 2 releasing the raw paper and the winding roller 3 winding the cut paper, the paper is guided by the difference in height of the first guide roller 29 and the second guide roller 30, which make the paper more regular.

[0041] This synchronously cleaned dust-free paper slitting device releases the raw paper through the paper roller 2 and rewinds the cut paper through the take-up roller 3. During cutting, the hinge arm 7 is rotated by the electric telescopic rod 9, causing the cutting blade 8 to descend. Cutting is performed while the paper is being pulled along. Because multiple sets of moving seats 6 move independently, the position of each set of moving seats 6 can be changed, thereby changing the position of multiple sets of cutting blades 8. This allows for easy adjustment of the slitting equal parts and spacing according to the cutting needs of the dust-free paper, making it widely applicable. Simultaneously, when replacing the paper roller 2, simply release the locking bolt 20, rotate and open the clamping arm 19, place the new paper roller 2 shaft into the bearing groove 21, reset the clamping arm 19, and tighten the locking bolt 20. Replacement is convenient and efficient. When it is necessary to remove the paper tube wound on the take-up roller 3, simply move the support assembly and pull the paper tube out from one end of the take-up roller 3, again achieving high efficiency. In addition, during the cutting process of the cutting blade 8, the suction is provided by the vacuum cleaner 17, which passes through the hose 18 to the dust cover 16 to easily pick up the splashed fibers and avoid polluting the environment.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
