Description

TECHNICAL FIELD

[0001] The application relates to the technical field of PVC plate processing, in particular to PVC plate surface finishing equipment. BACKGROUND

[0002] As a multifunctional and high-performance material, PVC plates are widely used in the fields of construction, home furnishing, electronic products, agricultural facilities and automobile industry, and have excellent durability, fire resistance and insulation, etc., which have brought revolutionary changes to various industries. With the development of science and technology and the diversification of social needs, the application prospect of PVC plates will be broader. In the field of construction and decoration, PVC plates have become an ideal choice for indoor and outdoor decoration due to their excellent durability, fire resistance and easy processing. They can be used for basic decoration such as ceiling, wall and floor, and can also be used to make various decorative lines, doors, windows and partitions, etc., to add a sense of fashion to the appearance of buildings. In order to ensure the beauty of the surface of the PVC plate, the PVC plate needs to be polished. In the traditional process, a large amount of dust is generated when the PVC plate is polished by a grinding wheel. Therefore, the dust needs to be recycled. However, the existing devices still have some problems in recycling dust. For example, the dust removal grinding wheel machine with publication number CN103331700A and the dust removal protective type grinding wheel machine with publication number CN108637912A both adopt the method of setting a fan below the grinding wheel to achieve the purpose of collecting the dust generated in the polishing process. However, the fan will produce a large amount of noise during the suction process, and a dust bag needs to be set at the exhaust end of the fan to filter the sucked air to prevent dust from overflowing. This method not only increases the noise, but also needs to be replaced and cleaned regularly, which is very inconvenient to use.

[0003] In addition, the anti-static polishing brush wheel with publication number CN110434759A removes the static electricity generated in the polishing process by setting anti-static adhesive filaments, so as to avoid the influence of dust adsorbed on the polishing wheel on the polishing effect of the plate. However, this method still causes dust to overflow in the air, and the static electricity on the surface of the plate cannot be discharged in time, so that a large amount of dust is still adsorbed on the plate, which is not conducive to the guarantee of the polishing effect and the rapid processing of the subsequent processing, and an additional cleaning process is needed to remove the dust on the surface of the plate.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the PVC board surface finishing equipment:

[0025] 1. The PVC board is clamped from both sides by side clamping rods, which keeps the PVC board stable during the sanding process. At the same time, the contact of the side clamping rods with the PVC board ensures the continuous discharge of static electricity from the surface of the PVC board.

[0026] Furthermore, by ensuring stable contact between the contact rod and the side clamp rod under the support of the spring, the side clamp rod can always maintain good grounding through the grounding wire at one end of the contact rod, thereby ensuring that the generated static electricity can be stably discharged and avoiding the situation where static electricity causes dust to adhere to the PVC board.

[0027] 2. The polishing wheel drives the polishing plate to rotate and is thrown out under the action of centrifugal force to polish the PVC board. The dust generated during the polishing process can be removed from the PVC board by the polishing plate through electrostatic adsorption, avoiding the noise generated by wind dust removal and the subsequent maintenance procedures.

[0028] Furthermore, when the polishing plate rotates into the cleaning column, the air is ionized by a corona discharge device to generate ions, which neutralizes the static electricity on the polishing plate. This causes the dust to lose its adsorption and fall into the collection box through the cleaning chamber under the action of centrifugal force, ensuring the collection of dust and preventing dust spillage.

[0029] Furthermore, by driving the central column to rotate simultaneously with the drive motor, the air collecting fan can be driven by the airflow to blow the ions generated by the corona discharger, so that the ions can fully contact the polishing plate to ensure the effect of static electricity removal, and the small air volume avoids dust being stirred up.

[0042] Please see Figures 1-11 The present invention provides a technical solution: a PVC board surface finishing equipment.

[0043] Example 1: This example discloses a base 1. A sliding side push seat 2 is installed on the outer surface of the base 1, and a mounting seat 3 is fixedly installed on the upper end of the side push seat 2. A rotating side clamping rod 4 is installed on the upper surface of one end of the mounting seat 3. A sliding contact rod 5 is installed on the upper surface of the side push seat 2. One end of the contact rod 5 is connected to one end of a grounding wire 6, and the other end of the grounding wire 6 passes through the lower surface of the base 1 and is connected to a round steel embedded in the ground. A spring is connected between the contact rod 5 and the mounting seat 3. One end of the contact rod 5 is arc-shaped, and the inner surface of the arc-shaped end of the contact rod 5 is in contact with the outer surface of the lower end of the side clamping rod 4. A clamping mechanism is provided on the lower surface of the base 1. The clamping of the workpiece by the side clamping rod 4 ensures efficient conduction of static electricity.

[0044] The clamping mechanism includes: a clamping electric push rod 7, which is fixedly mounted on the lower surface of the base 1, and a clamping frame 8 is fixedly connected to one end of the clamping electric push rod 7. The clamping frame 8 is slidably connected to the base 1. A guide groove 9 is provided on the lower outer surface of the side push seat 2. A rod-shaped protrusion with a T-shaped longitudinal section is provided on the lower end of the clamping frame 8. The guide groove 9 is T-shaped and oblique. Two adjacent guide grooves 9 are arranged in a figure-eight shape. The clamping frame 8 is slidably connected to the guide groove 9 through the rod-shaped protrusion.

[0045] During processing, the workpiece is first placed on the upper surface of the base 1, and then the clamping electric push rod 7 is activated. The clamping electric push rod 7 drives the clamping frame 8 to slide relative to the base 1, so that the clamping frame 8 slides in the inclined guide groove 9 through the T-shaped rod-shaped protrusion. This causes the side push seat 2 to be squeezed and pushed to slide relative to the base 1. At this time, the side push seat 2 drives the side clamping rod 4 to contact the workpiece through the mounting seat 3 to clamp the workpiece. At the same time, the contact rod 5 always keeps in contact with the outer surface of the side clamping rod 4 under the support of the spring between it and the mounting seat 3. When static electricity is generated during processing, the static electricity can be quickly conducted through the grounding wire 6.

[0046] Example 2: Based on Example 1, this example discloses that the outer surface of the base 1 is provided with an anti-slip pushing mechanism, which ensures the grinding effect and the stable contact between the side clamping rod 4 and the workpiece through a stable pushing method, thus ensuring electrostatic conduction.

[0047] The anti-slip pushing mechanism includes: a linear displacement module 10, which is installed on the lower surface of the base 1. A guide rod 11 is fixedly installed on the lower surface of the base 1, and a sliding bottom pusher 12 is installed on the outer surface of the guide rod 11. A rotating support wheel 13 is installed on the inner surface of the base 1 between the linear displacement module 10 and the guide rod 11. A PVC plate 14 is placed on the upper surface of the support wheel 13. A fixing frame 15 is fixedly installed on the upper surface of the base 1. A pressing electric push rod 16 is fixedly installed on the upper surface of the fixing frame 15. A pressing frame 17 is fixedly connected to the lower end of the pressing electric push rod 16, and a rotating pressing wheel 18 is installed on the lower surface of the pressing frame 17.

[0048] The linear displacement module 10 is threadedly connected to the bottom push frame 12, and the bottom push frame 12 has a T-shaped design. One end of the bottom push frame 12 is located between two support rollers 13 on the inner surface of the base 1. The pressure rollers 18 are evenly distributed on the lower surface of the pressure frame 17, and the lower surface of the pressure rollers 18 protrudes from the lower surface of the pressure frame 17.

[0049] After the PVC board 14 is installed, the electric push rod 16 on the fixed frame 15 is activated to drive the pressing frame 17 to slide down, so that the pressing frame 17 can press the PVC board 14 onto the outer surface of the support wheel 13 through the pressing wheel 18. At this time, the displacement linear module 10 is activated. The displacement linear module 10 drives the bottom push frame 12 to slide relative to the base 1 on the guide rod 11 through the threaded connection with the bottom push frame 12. During the process, the bottom push frame 12 pushes the PVC board 14 to move stably by contacting one end of the PVC board 14 with its upper end.

[0050] Example 3: Based on Examples 1 and 2, this example discloses that the outer surface of the middle section of the base 1 is provided with a polishing mechanism, which ensures the static elimination effect and prevents dust generation by continuously polishing and removing static electricity in real time;

[0051] The polishing mechanism includes: a drive motor 19, which is fixedly installed inside the lower surface of the base 1. A central column 21 is fixedly connected to the upper end of the output shaft of the drive motor 19, penetrating the upper surface of the base 1. An air-collecting fan 20 is fixedly connected to the outer surface of one end of the drive motor 19's output shaft inside the base 1. A rotating limiting plate 22 is installed on the upper surface of the central column 21, and a limiting post 23 is fixedly installed on the upper surface of the central column 21. A sliding polishing wheel 24 is sleeved on the outer surface of the central column 21, and a sliding polishing plate 25 is installed on the side surface of the polishing wheel 24. A sliding polishing plate 25 is installed on one side of the central column 21. A cleaning column 26 is fixedly installed on the upper surface of the base 1, and a cleaning cavity 27 is opened on the inner surface of the cleaning column 26. A corona discharger 28 is fixedly installed inside the upper end of the cleaning column 26. One end of the guide pipe 29 is fixedly connected to the upper end of the cleaning column 26, and the other end of the guide pipe 29 penetrates the side surface of the cavity inside the base 1 where the air collecting fan 20 is located. An air inlet 30 is opened on the bottom surface of the cavity inside the base 1 where the air collecting fan 20 is located, and the lower end of the air inlet 30 penetrates the lower surface of the base 1. A magnetic column 31 is fixedly installed on the lower surface of the base 1, and a collection box 32 is engaged with the side surface of the magnetic column 31.

[0052] The outer surface of the central column 21 is provided with petal-shaped protrusions, and the central column 21 is engaged with the polishing wheel 24 through the petal-shaped protrusions. The vertical projection of the limiting plate 22 is completely covered by the vertical projection of the central column 21, and the vertical projection of the limiting plate 22 does not overlap with the vertical projection of the limiting column 23. The upper end face of the polishing wheel 24 is flush with the upper end face of the central column 21. The polishing plate 25 is arc-shaped, and a spring is connected between the polishing plate 25 and the polishing wheel 24. The polishing plate 25 is evenly distributed on the outer surface of the polishing wheel 24.

[0053] The cleaning column 26 has an arc-shaped design, and the two ends of the cleaning column 26 have a smooth bevel design. The outer surface of the base 1 below the cleaning column 26 has a hollow design, and the inner surface of the cleaning column 26 is in contact with the outer surface of the polishing wheel 24.

[0054] The upper end of the guide tube 29 passes through the inner cavity of the upper end of the cleaning column 26 where the corona discharger 28 is located, and the inner cavity of the upper end of the cleaning column 26 where the corona discharger 28 is located is connected to the cleaning chamber 27. The lower end of the guide tube 29 and the upper end of the air inlet 30 are located on the upper and lower sides of the air collecting fan 20, respectively. The collection box 32 has an arc-shaped design and is located directly below the hollow part of the base 1.

[0055] During the movement of the PVC board 14, the drive motor 19 starts, driving the air collecting fan 20 and the central column 21 to rotate. At this time, the limiting plate 22 at the upper end of the central column 21 rotates relative to the central column 21 under the action of centrifugal force until one end of the limiting plate 22 is blocked by the limiting column 23. At this time, the limiting plate 22 and the central column 21 are misaligned, so that the polishing wheel 24 sleeved on the surface of the central column 21 will not slide up and down during rotation, causing instability. During the rotation of the polishing wheel 24, the polishing plate 25 slides relative to the polishing wheel 24 under the action of centrifugal force and stretches the spring between the polishing wheel 24, so that the polishing plate 25 can contact the outer surface of the PVC board 14 for polishing. The dust generated is adsorbed by the polishing plate 25 and carried away from the PVC plate 14. When the polishing plate 25 rotates to the inclined surfaces at both ends of the cleaning column 26, the polishing plate 25 is compressed back into the side surface of the polishing wheel 24 until the polishing plate 25 rotates to face the cleaning chamber 27. Due to the rotation of the air collecting fan 20, external air is drawn in through the air inlet 30 and injected downward into the cleaning chamber 27 through the guide pipe 29. During the process, the corona discharger 28 ionizes the air to generate a large number of positive and negative ions. With the flow of air, the ions neutralize the static charge on the polishing plate 25, so that the dust on the polishing plate 25 can lose its adsorption and fall through the hollowed-out area on the outer surface of the base 1 into the collection box 32 installed by the magnetic column 31 and be collected.
