Description

Technical Field

[0001] The present invention belongs to the technical field of cork processing, and particularly relates to a precision cork cutting machine and a negative pressure purification component. Background Art

[0002] As a light and excellent elastic natural material, cork is widely used in fields such as sealing products, decorative materials, and industrial buffer parts. Traditional cork processing equipment has significant defects in cutting accuracy, clamping stability, and dust control, restricting the production of high-value-added products. Starting from the pain points of the existing technology, the innovative advantages of this solution (a precision cork cutting machine and a negative pressure purification component) are compared and analyzed as follows:

[0003] The main defects of the existing technology are insufficient cutting accuracy. Most traditional cutting machines directly drive rigid tools without a buffer mechanism, resulting in large vibrations during cutting, high burr rates on the edges of cork (usually >5%), and difficulty in meeting the tolerance requirements of precision seals (such as ±0.1 mm). For a certain type of hydraulically driven cutting machine, the tool wear rate reaches 0.3 mm / hour when cutting cork, and the tool needs to be frequently replaced. The clamping system damages the material, and mechanical jaws or pneumatic suction cups are likely to cause surface indentations or tears on the cork, especially for thin cork boards with a thickness <5 mm, and the scrap rate is as high as 15% - 20%. Industry research shows that cork losses caused by improper clamping account for more than 12% of the raw material cost. Serious dust pollution, the open cutting design leads to the diffusion of fine particle dust (PM2.5 - PM10), and the capture efficiency of traditional bag filters for cork debris is only 60% - 70%, and the air quality in the workshop is often lower than the OSHA standard (PM2.5 limit value 15 μg / m 3 ) Summary of the Invention

[0017] Further, the collection shell is mutually matched with the baffle plate.

[0018] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0019] (1) In the present invention, the cutting assembly adopts a belt pulley drive system composed of a double driving pulley and a cutting motor, and realizes the high-speed rotation of the cutter through synchronous belt transmission. This structure has high transmission efficiency, low power loss, and the flexible connection of the belt pulley drive can effectively buffer the cutting impact, extend the service life of the cutter. A protective shell is arranged around the cutter, which can not only prevent the cutting debris from splashing, but also reduce the operation risk. The nested design of the protective shell and the negative pressure shell realizes the fully enclosed protection of the cutting area, and at the same time provides a directional channel for negative pressure dust collection, improving the safety. The shaft sleeve is fixed to the mounting plate by bolts, and the cutter is installed in an embedded manner on the rotating shaft, which is convenient for quick disassembly, maintenance or replacement of cutters of different specifications, and adapts to diverse cutting requirements.

[0020] (2) In the present invention, the flat clamping assembly realizes the preliminary fixation through the clamping cylinder driving the clamping plate with rubber strips, and cooperates with the secondary pressurization of the extrusion cylinder and the extrusion wheel to form a hierarchical clamping force control. The elastic contact of the rubber strips can avoid damaging the surface of the cork, and at the same time, the rolling pressure of the extrusion wheel ensures that the cork remains flat during movement. The limiting slide rail and the lead screw drive form a moving assembly, and cooperate with the closed-loop control of the moving motor to achieve the micron-level precision of the horizontal movement of the cutting table. The double guiding system of the limiting rollers and the guiding wheels effectively reduces the offset of the moving frame and ensures the linearity of the cork feeding. The moving frame is equipped with a long-stroke cylinder and a return spring, and automatically adjusts the retraction amount of the extrusion plate according to the thickness of the cork during the cutting process. The combined design of the limiting rod and the return spring can absorb mechanical vibration and prevent the clamping failure caused by the deformation of the cork.

[0021] (3) In the present invention, for the negative pressure purification component, the negative pressure shell is connected to an external negative pressure device through a hose to adsorb the fine particulate dust generated by cutting in real time; the collection shell uses high-speed airflow to directionally capture large particulate debris, achieving dust classification treatment, significantly enhancing the service life of the filtration system. The cleaning cylinder drives the collection shell to move along the path of the drag reduction wheel. Combining with the centrifugal force generated by the rotation of the cutting tool, the accumulated debris in the baffle area is actively ejected into the collection shell, covering the debris blind area throughout the cutting process. The dual collection shell alternating working mode: on one side, negative pressure adsorption is carried out, and on the other side, high-speed airflow is injected to form a local eddy current, enhancing the debris collection efficiency in a low-energy consumption manner and reducing the continuous load of the external negative pressure device.

[0022] (4) In the present invention, the bottom groove of the workbench cooperates with the lifting trolley to achieve continuous batch feeding of cork. The sequential control of the feeding cylinder and the long-stroke cylinder ensures seamless connection of the feeding, clamping, and cutting processes. The integrated PLC control module of the moving motor and the stroke cylinder supports preset cutting parameters, reducing the operation complexity. Through the synergistic effect of the three components, while ensuring the cutting accuracy, it systematically solves the pain points such as clamping deformation and dust pollution in cork processing, and has high industrial application value.

The clamping cylinder 30 is started, so that the clamping plate 31 drives the rubber strip 32 to clamp the cork. After the initial clamping is completed, the extrusion cylinder 18 is started, so that the extrusion cylinder 18 drives the extrusion plate 24 to descend, and the extrusion wheel 28 is used to assist in extruding the cork to ensure that the cork is in a flat state during cutting. Subsequently, the long-stroke cylinder 12 is started continuously, so that the moving frame 17 and the extrusion plate 24 continue to approach the blocking plate 5. Then the moving motor 20 is started, and the screw rod drives the moving block 21 to move inside the limit slide rail 19, further driving the moving frame 13 to move horizontally. Finally, under the limitation of the guide plate 14 and the resistance-reducing wheel 15, one side of the outer wall of the mounting frame 29 fits against one side of the cork. Therefore, under the drive of the moving frame 13 and the mounting frame 29, the cork continuously approaches the blocking plate 5. At this time, the moving frame 17 and the extrusion plate 24 generate a retracting action. At this time, the guide wheel 27 installed on the moving frame 17 slides inside the limit groove 1301 and is further limited by the limit rod 25. At this time, one side of the outer wall of the cork has fit against the outer wall of the blocking plate 5. The cutting motor 22 is started, so that the transmission wheel 9 drives the cutter 7 to rotate at a high speed. Under the action of the blocking plate 5, the cork continuously approaches the cutter 7. A large amount of dust is generated during the cutting process, and the dust is continuously absorbed by the negative pressure shell 6. Large particle debris accumulates in the space between the cutting table 2 and the blocking plate 5. When the collection shell 23 on the side gradually away from the cutter 7 can avoid contacting the cutter 7 during cutting, the corresponding cleaning cylinder 16 is started, so that the collection shell 23 passes through the bottom of the resistance-reducing wheel 15 and approaches the blocking plate 5. Finally, the large particle debris generated is sprayed into the interior of the collection shell 23 under the high-speed rotation of the cutter 7. Another collection shell 23 injects high-speed air flow, so that the air flow drives the debris to approach the negative pressure collection shell 23. After cutting, the cut cork falls onto the workbench 1 under the action of the blocking plate 5. For the remaining cork, under the action of the extrusion plate 24, the cork is continuously extruded. Finally, the moving motor 20 is reversed to drive the moving frame 17 and the extrusion plate 24 away from the cutter 7. Finally, the above cutting steps are continuously repeated until all the cork is cut into cork strips. Finally, the moving frame 17 and the extrusion plate 24 are reset, and feeding is carried out again. The cutting assembly adopts a belt drive system composed of a double transmission wheel 9 and a cutting motor 22, and the cutter 7 is driven to rotate at a high speed through synchronous belt transmission. This structure has high transmission efficiency, low power loss, and the flexible connection of the belt drive can effectively buffer the cutting impact and extend the service life of the cutter 7. A protective shell 8 is arranged around the cutter 7, which can not only prevent cutting debris from splashing, but also reduce the operation risk. The protective shell 8 and the negative pressure shell 6 are nested designed to achieve a fully enclosed protection of the cutting area, and at the same time provide a directional channel for negative pressure dust collection to improve safety. The bushing 4 is fixed to the mounting plate 3 by bolts, and the cutter 7 is installed in an embedded manner on the rotating shaft, which is convenient for quick disassembly, maintenance or replacement of cutters 7 of different specifications to adapt to diverse cutting requirements.The flat clamping assembly realizes preliminary fixation by driving the clamping plate 31 with a rubber strip 32 through a clamping cylinder 30. In cooperation with the secondary pressurization of the extrusion cylinder 18 and the extrusion wheel 28, it forms a hierarchical clamping force control. The elastic contact of the rubber strip 32 can avoid damage to the surface of the cork. At the same time, the rolling pressure of the extrusion wheel 28 ensures that the cork remains flat during movement. The limit slide rail 19 and the screw drive form a moving assembly. In cooperation with the closed-loop control of the moving motor 20, it realizes the micron-level precision of the lateral movement of the cutting table 2. The double guiding system of the limit roller 34 and the guiding wheel 27 effectively reduces the offset of the moving frame 17 and ensures the linearity of the cork feeding. The moving frame 13 is equipped with a long-stroke cylinder 12 and a return spring 26, which automatically adjusts the retraction amount of the extrusion plate 24 according to the thickness of the cork during the cutting process. The combined design of the limit rod 25 and the return spring 26 can absorb mechanical vibrations and prevent clamping failure caused by cork deformation. The negative pressure purification assembly, the negative pressure shell 6 is connected to an external negative pressure device through a hose to adsorb the fine particle dust generated by cutting in real time; the collection shell 23 uses high-speed airflow to directionally capture large particle debris, realizing dust classification treatment and significantly improving the service life of the filtration system. The cleaning cylinder 16 drives the collection shell 23 to move along the path of the drag-reducing wheel 15. Combining with the centrifugal force generated by the rotation of the cutter 7, the accumulated debris in the area of the baffle 5 is actively projected into the collection shell 23 to cover the debris blind area throughout the cutting process. The alternating working mode of the double collection shell 23: one side adsorbs through negative pressure, and the other side injects high-speed airflow to form a local eddy current, enhancing the debris collection efficiency in a low-energy consumption manner and reducing the continuous load of the external negative pressure device. The bottom groove of the workbench 1 cooperates with the lifting trolley to realize the batch continuous feeding of the cork. The sequential control of the feeding cylinder 10 and the long-stroke cylinder 12 ensures the seamless connection of the feeding-clamping-cutting process. The moving motor 20 and the stroke cylinder are integrated with a PLC control module, which supports preset cutting parameters and reduces the operation complexity. Through the synergistic effect of the three components, while ensuring the cutting precision, it systematically solves the pain points such as clamping deformation and dust pollution in cork processing and has high industrial application value.

A long-stroke cylinder 12 is fixedly arranged on the outer wall of the moving block 21. The long-stroke cylinder 12 has a stroke control function, which can facilitate the adjustment of the distance of the cork.

[0036] Refer to Figure 1 - Figure 8 : The output end of the long-stroke cylinder 12 is fixedly arranged on the outer wall of the moving frame 13. A feeding port 201 is opened at the top of the outer wall of the cutting table 2.

[0037] The following will detail the usage method of a precision cork cutting machine and a negative pressure purification component provided by an embodiment of the present invention. The usage method includes the following steps:

[0038] Feeding stage:

[0039] Step 1: Cork loading. Place the cork raw material on the lifting trolley at the bottom of the workbench 1. Push the trolley along the groove into the lower part of the workbench 1, and lift the cork to the position of the feeding port 201 of the cutting table 2 through the lifting function of the trolley.

[0040] Step 2: Automatic feeding. Start the feeding cylinder 10, push the feeding plate 11 to move along the cutting table 2, and smoothly transport the cork from the feeding port 201 to the top processing area of the cutting table 2.

[0041] Clamping and positioning stage:

[0042] Step 3: Preliminary clamping. The long-stroke cylinder 12 drives the moving frame 13 to move towards the baffle 5, so that the moving frame 17 and the extrusion plate 24 move above the cork. Start the clamping cylinder 30 to drive the clamping plate 31 and the rubber strip 32 to elastically clamp the cork to avoid surface damage.

[0043] Step 4: Secondary extrusion and leveling. Start the extrusion cylinder 18 to push the extrusion plate 24 downward, and apply rolling pressure to the cork through the extrusion wheel 28 to eliminate unevenness or warping on the surface of the cork and ensure that the cork is in a stable state during cutting.

[0044] Step 5: Precise positioning. The long-stroke cylinder 12 continues to push the moving frame 13 closer to the baffle 5. The moving motor 20 drives the moving block 21 to move horizontally along the limit slide rail 19 through the lead screw, driving the moving frame 13 to adjust the horizontal position. The guide wheel 27 slides along the limit groove 1301, and the limit rod 25 and the return spring 26 cooperate to control the retraction amount of the moving frame 17, and finally make one side of the cork close to the baffle 5 to complete precise positioning.

[0045] Cutting and dust removal stage:

[0046] Step 6: Start cutting. The cutting motor 22 drives the cutter 7 to rotate at high speed through the transmission wheel 9 and the synchronous belt. The cork continues to move closer to the cutter 7 under the push of the moving frame 13 and the mounting frame 29 to complete the cutting action.

[0047] Step 7: Negative pressure dust collection. The fine particle dust generated by cutting is adsorbed in real time by the negative pressure shell 6 and conveyed to the external negative pressure collection device through a hose; the large particle debris accumulates in the space between the cutting table 2 and the baffle 5.

[0048] Step 8: Active debris cleaning. When the cutting position is far from one side of the cutter 7, start the cleaning cylinder 16 to drive the collection shell 23 to move along the path of the drag reduction wheel 15 to the area of the baffle 5. The centrifugal force generated by the rotation of the cutter 7 throws the large particle debris into the collection shell 23; another collection shell 23 forms a vortex through high-speed air flow to assist in adsorbing debris, realizing alternating and efficient collection.

[0049] Reset and cycle stage:

[0050] Step 9: Reset after cutting. The cut cork strips fall onto the workbench 1 under the guidance of the baffle 5, and the remaining cork is fixed under the continuous pressure of the extrusion plate 24. The moving motor 20 rotates in reverse to drive the moving frame 13 and the extrusion plate 24 away from the cutter 7 and reset to the initial position.

[0051] Step 10: Cycle cutting. Repeat steps 3 to 9 until the whole piece of cork is completely cut into cork strips. Then the moving frame 17 and the extrusion plate 24 are completely reset, and the feeding cylinder 10 is restarted to enter the next batch of feeding cycle.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
