Description

Technical Field

[0001] This utility model relates to the field of cleanroom cloth processing, specifically to a cleanroom cloth cross-cutting mechanism. Background Technology

[0002] Cleanroom wipe cross-cutting mechanism is an important piece of equipment in the production and processing of cleanroom wipes. It is mainly used to cut continuously conveyed cleanroom wipes laterally to obtain finished products of a specific length. It is commonly used in cleanroom wipe production processes in industries with high requirements for cleanroom environment, such as electronics, pharmaceuticals, and precision manufacturing.

[0003] In traditional cleanroom wipe cross-cutting equipment, the disassembly and replacement of blades is often complex, causing considerable inconvenience for daily maintenance. Inadequate drive structure design leads to poor blade stability and insufficient precision during cutting, making it difficult to guarantee consistency in each cut. During operation, significant impacts and vibrations between components not only generate loud noise but also easily cause deviations in the cutting position, affecting cutting accuracy. Furthermore, some structural components are not tightly fitted, resulting in transmission gaps that cause uneven cuts and numerous burrs on the cleanroom wipes, negatively impacting product quality. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned defects and provide a cleanroom cloth cross-cutting mechanism. It solves the problems of the unreasonable design of the existing drive structure, which leads to poor stability and accuracy of the cutter during cutting, making it difficult to ensure the consistency of each cutting process; the large impact and vibration between the components during equipment operation, which not only produces loud noise, but also easily causes deviation in the cutting position due to vibration, affecting the cutting accuracy; at the same time, the fit of some structures is not tight enough, and there is a certain transmission gap, which makes the cut cleanroom cloth cut edge irregular and has more burrs, which has an adverse effect on product quality.

[0005] The purpose of this utility model is achieved through the following means: a cleanroom cloth cross-cutting mechanism, including a support member, a limiting member, a fixing member, and a back plate, wherein the limiting member is disposed at the upper end of the support member, the fixing member is assembled in the inner cavity of the limiting member, and the back plate is assembled in the interior of the fixing member.

[0006] The back plate has main tubes evenly arranged inside, and secondary tubes are slidably arranged at the bottom of the main tubes. The secondary tubes and the main tubes are vacuum-sealed. The bottom of the secondary tubes is provided with a snap-fit ​​component, and a cutting tool is snapped into the bottom of the snap-fit ​​component. The back plate has a drive mechanism outside, which includes a drive component. The output end of the drive component is connected to a disc.

[0007] The disc is externally connected to a circular shaft, and a collar is fitted around the outside of the circular shaft. A linkage is located at the bottom of the collar, and the bottom of the linkage is rotatably connected to the top of the snap-fit ​​component. When the drive unit is activated, it causes the disc to rotate, and the circular shaft outside the disc rotates accordingly, causing the collar to reciprocate under the action of the circular shaft. The collar drives the snap-fit ​​component to move up and down through the linkage, thereby causing the secondary pipe component to slide within the main pipe component.

[0008] Because the secondary tube and the main tube are designed with a vacuum, air resistance and friction loss during relative sliding are reduced, making the sliding of the secondary tube smoother and more stable. This ultimately enables the reciprocating cross-cutting motion of the tool. The power transmission of the drive mechanism is continuous and stable, allowing the cross-cutting motion of the tool to be precise and smooth, effectively improving the accuracy and efficiency of the cleanroom cloth cross-cutting and reducing cutting deviations caused by unstable motion.

[0009] Furthermore, a dust collection mechanism is connected to both the left and right sides of the support member, a frame is provided at the bottom of the dust collection mechanism, and a suction head is connected to the air inlet end of the dust collection mechanism.

[0010] When the blade makes a cross-cut on the cleanroom cloth, the dust collection mechanism activates to generate negative pressure, drawing in dust and debris generated during the cutting process through the suction head. This timely removal of impurities prevents dust from adhering to the cleanroom cloth surface or spreading to other parts of the equipment, ensuring the cleanliness of the cleanroom cloth and maintaining a clean working environment, thus reducing contamination and wear on equipment components.

[0011] Furthermore, the top of the support member is provided with a transverse groove, the inner cavity of which is slidably connected to the bottom of the cutter. When the cutter performs a transverse cutting motion, its bottom is embedded in the transverse groove at the top of the support member and slides along the groove. The transverse groove restricts and guides the movement trajectory of the cutter. This effectively prevents the cutter from shifting left or right or wobbling during the cutting process, ensuring that the cutter always cuts along a preset trajectory, improving the straightness and consistency of the cut, and reducing burrs and irregularities on the cut edges of the lint-free cloth.

[0012] Furthermore, a motor mount is provided at the bottom of the drive component, and the motor mount is connected to the outside of the back plate via reinforcing ribs. The motor mount provides a stable mounting base for the drive component, and the reinforcing ribs further enhance the strength and rigidity of the connection between the motor mount and the back plate, allowing the vibration and impact forces generated by the drive component during operation to be effectively transmitted to and dispersed by the motor mount and reinforcing ribs. This prevents the drive component from shifting or loosening due to vibration, ensures the stability of the drive component's operation, reduces the impact of vibration on the power transmission of the entire drive mechanism, and extends the service life of the drive component and related components.

[0013] Furthermore, the front of the back plate is uniformly provided with support platforms, the inner cavity of which is slidably connected to the outside of the secondary tube. When the secondary tube slides up and down within the main tube, the inner cavity of the support platform provides support and guidance to the outside of the secondary tube, limiting its radial sway. This ensures a more precise sliding trajectory for the secondary tube, preventing positional shifts in the clamping parts and the cutting tool due to the secondary tube's sway, and further improving the stability and reliability of the cutting tool's transverse cutting action.

[0014] Furthermore, the blade has ventilation slots on its exterior, and a 30° acute-angle diamond-coated blade is installed at the bottom. The ventilation slots allow for smoother airflow in the cutting area, and, in conjunction with the dust extraction mechanism, more efficiently remove dust. The 30° acute-angle blade design reduces the contact area during cutting, lowering cutting resistance, while the diamond coating significantly improves the blade's hardness and wear resistance. The ventilation slots enhance dust removal efficiency, ensuring the cleanliness of the cut surface of the lint-free cloth; the acute-angle design makes the cut sharper, reducing strain on the lint-free cloth and lowering the probability of burrs; the diamond coating extends the blade's lifespan, reducing replacement frequency and lowering maintenance costs.

[0015] The beneficial effects of this utility model are:

[0016] This cleanroom wipe cross-cutting mechanism, by incorporating a main tube and a sliding secondary tube inside the back plate and employing a vacuum design, along with a snap-fit ​​mechanism for the cutter, allows for convenient and quick cutter removal and replacement, improving maintenance ease. The drive mechanism, through a disc, collar, and linkage, moves the snap-fit ​​mechanism, making the cutter's cutting action more stable and precise, helping to ensure consistency in the cutting process. The vacuum design of the main and secondary tubes provides effective buffering, reducing impact and vibration during operation. This not only lowers the noise level during equipment operation but also avoids cutting deviations caused by mechanical vibration, improving cutting accuracy, reducing unnecessary transmission backlash, ensuring clean cuts, minimizing burrs, and ultimately guaranteeing the cutting quality of the cleanroom wipe.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] In this embodiment, refer to Figure 1 , Figure 2 and Figure 3 The specific implementation of the cleanroom cloth cross-cutting mechanism includes a support member 1, a limiting member 2, a fixing member 3, and a back plate 4. The limiting member 2 is disposed at the upper end of the support member 1, the fixing member 3 is assembled in the inner cavity of the limiting member 2, and the back plate 4 is assembled in the interior of the fixing member 3.

[0023] The back plate 4 has a main tube 5 evenly arranged inside. A secondary tube 54 is slidably arranged at the bottom of the main tube 5. The secondary tube 54 and the main tube 5 are designed with a vacuum. A snap-fit ​​part 51 is arranged at the bottom of the secondary tube 54. A tool 52 is snapped at the bottom of the snap-fit ​​part 51. A drive mechanism 6 is arranged outside the back plate 4. The drive mechanism 6 includes a drive part 61. The output end of the drive part 61 is connected to a disk 62.

[0024] The disc 62 is externally connected to a circular shaft, and a collar 63 is fitted around the outside of the circular shaft. A linkage 64 is provided at the bottom of the collar 63, and the bottom of the linkage 64 is rotatably connected to the top of the snap-fit ​​member 51. After the drive unit 61 is started, it drives the disc 62 to rotate, and the circular shaft outside the disc 62 rotates with it, causing the collar 63 to reciprocate under the action of the circular shaft. The collar 63 drives the snap-fit ​​member 51 to move up and down through the linkage 64, thereby causing the secondary tube 54 to slide within the main tube 5.

[0025] Because the secondary tube 54 and the main tube 5 are designed with a vacuum, the air resistance and friction loss during relative sliding can be reduced, making the sliding of the secondary tube 54 smoother and more stable. Ultimately, the reciprocating cross-cutting action of the cutter 52 is realized. The power transmission of the drive mechanism 6 is continuous and stable, which can make the cross-cutting motion of the cutter 52 precise and stable, effectively improving the accuracy and efficiency of the cleanroom cloth cross-cutting and reducing the cutting deviation caused by unstable motion.

[0026] The support member 1 is connected to a vacuuming mechanism 11 on both the left and right sides. The bottom of the vacuuming mechanism 11 is equipped with a frame, and the air inlet end of the vacuuming mechanism 11 is connected to a suction head 12.

[0027] When the cutter 52 makes a cross-cut on the cleanroom cloth, the dust collection mechanism 11 is activated to generate negative pressure. The dust and debris generated during the cutting process are sucked into the dust collection mechanism 11 through the suction head 12. This timely removal of impurities generated during cutting prevents dust from adhering to the surface of the cleanroom cloth or falling to other parts of the equipment, ensuring the cleanliness of the cleanroom cloth and maintaining a clean working environment for the equipment, thus reducing contamination and wear on equipment components caused by impurities.

[0028] The top of the support member 1 has a transverse groove, the inner cavity of which is slidably connected to the bottom of the cutter 52. When the cutter 52 performs a transverse cutting motion, its bottom is embedded in the transverse groove at the top of the support member 1 and slides along the groove. The transverse groove restricts and guides the movement trajectory of the cutter 52. This effectively prevents the cutter 52 from shifting left or right or wobbling during the cutting process, ensuring that the cutter 52 always performs transverse cutting along a preset trajectory, improving the straightness and consistency of the cut, and reducing burrs and irregularities on the cut edges of the lint-free cloth.

[0029] A motor mount is located at the bottom of the drive component 61, and the motor mount is connected to the outside of the back plate 4 via reinforcing ribs. The motor mount provides a stable mounting base for the drive component 61, and the reinforcing ribs further enhance the strength and rigidity of the connection between the motor mount and the back plate 4, allowing the vibration and impact forces generated by the drive component 61 during operation to be effectively transmitted to and dispersed by the motor mount and reinforcing ribs. This prevents the drive component 61 from shifting or loosening due to vibration, ensures the stability of the drive component 61 during operation, reduces the impact of vibration on the power transmission of the entire drive mechanism 6, and extends the service life of the drive component 61 and related components.

[0030] Support platforms 53 are evenly distributed on the front of the back plate 4, and the inner cavity of the support platform 53 is slidably connected to the outside of the secondary pipe 54. When the secondary pipe 54 slides up and down within the main pipe 5, the inner cavity of the support platform 53 provides support and guidance for the outside of the secondary pipe 54, limiting the radial sway of the secondary pipe 54. This ensures a more precise sliding trajectory for the secondary pipe 54, preventing positional displacement of the clamping part 51 and the cutter 52 due to the swaying of the secondary pipe 54, and further improving the stability and reliability of the cross-cutting action of the cutter 52.

[0031] The cutting tool 52 has ventilation slots on its exterior, and a 30° acute-angle diamond-coated blade is installed at the bottom of the cutting tool 52. The ventilation slots allow for smoother airflow in the cutting area, and together with the dust extraction mechanism 11, they can more efficiently remove dust; the 30° acute-angle blade design reduces the contact area during cutting, reducing cutting resistance, while the diamond coating significantly improves the hardness and wear resistance of the blade. The ventilation slots improve dust removal efficiency, ensuring the cleanliness of the cut surface of the lint-free cloth; the acute-angle design makes the cut sharper, reduces the pulling on the lint-free cloth, and reduces the probability of burrs; the diamond coating extends the life of the blade, reduces the frequency of replacement, and lowers maintenance costs.

[0032] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
