Description

Technical Field

[0001] This utility model belongs to the field of polishing and dust collection technology, specifically relating to a polishing and dust collection platform for plastic workpieces. Background Technology

[0002] Manual polishing is a common surface treatment process in the processing of plastic parts, especially for precision parts such as plastic rearview mirror housings, which require manual operation for fine polishing. However, in existing technologies, the manual polishing process generates a large amount of dust. If this dust is not effectively collected and treated, it can easily spread into the working environment, causing dust pollution in the workshop, affecting air quality, and posing a health hazard to operators. Traditional polishing platforms often lack a complete sealed dust collection structure. Although some equipment is equipped with simple dust collection devices, the lack of reliable sealing and isolation between the polishing area and the external space allows dust to easily spill out from the operating port, equipment gaps, and other areas. Utility Model Content

[0003] The purpose of this invention is to provide a dust collection platform for polishing plastic workpieces, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a polishing and dust collection platform for plastic workpieces, comprising:

[0005] The polishing platform has a hollow vertical plate on one side of its end, which is equipped with a dust suction and filtration component for polishing. The hollow vertical plate is equipped with a dust suction and filtration mechanism for polishing and filtration. The front end of the hollow vertical plate is equipped with a transparent polishing guard frame in a closed space during manual polishing of plastic rearview mirror shell workpieces on the polishing platform via a detachable hinge.

[0006] The bottom of one side of the transparent polished protective frame is fixed with rivets, which is conducive to the removal and placement of plastic rearview mirror housing workpieces and the sealing of the outside of the inlet and outlet. The soft transparent protective frame is provided with arched holes that allow workers to put their hands into the transparent polished protective frame and fit it on their arms to reduce dust leakage.

[0007] Preferably, the transparent polishing frame is provided with a sealing strip at the position where it is attached to the surface of the hollow vertical plate, and the bottom of the transparent polishing frame is sealed and attached to the surface of the polishing platform to form a polishing space with the hollow vertical plate. The access port on one side of the transparent polishing frame is sealed with a soft transparent sealing plate.

[0008] Preferably, the dust collection and filtration mechanism includes a dust collection hood disposed on one side of the bottom of the hollow vertical plate, the other side of the dust collection hood is connected to an industrial vacuum cleaner, and the outlet end of the industrial vacuum cleaner is connected to a filter disposed on the upper side of the hollow vertical plate through a pipe.

[0009] Preferably, the dust suction port of the dust suction hood extends to the outside of the hollow vertical plate and is located in the sealed polishing space to adsorb dust. The top of the interior of the polishing space is equipped with a monitoring sensor for detecting dust concentration.

[0010] Preferably, the polishing platform is provided with polishing power supplies on both sides of the bottom, and each polishing power supply is electrically connected to a polishing machine body for manually polishing the plastic rearview mirror housing workpiece in the polishing space via wires.

[0011] Preferably, the polishing platform has through holes on both sides of its end, and elastic sealing sleeves are provided inside the through holes.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a polishing and dust collection platform for plastic workpieces, comprising:

[0024] The polishing platform 1 has a hollow vertical plate 2 at one end, which houses the dust collection and filtration components for polishing. The hollow vertical plate 2 is equipped with dust collection and filtration mechanisms 7 for polishing and dust collection. The front end of the hollow vertical plate 2 is connected to a transparent polishing guard 4, which is in a closed space during manual polishing of plastic rearview mirror housing workpieces on the polishing platform 1, via a hinge 3. The hinge 3 is made of stainless steel and can open and close the transparent polishing guard 4 180°, facilitating equipment maintenance and workpiece loading and unloading.

[0025] The bottom of one side of the transparent polished protective frame 4 is fixed with rivets to a soft transparent sealing plate 5, which facilitates the removal and placement of plastic rearview mirror housing workpieces and the sealing of the outer side of the inlet and outlet. The soft transparent sealing plate 5 is provided with an arched hole 6, which allows the operator's hand to reach into the transparent polished protective frame 4 and fit against the arm to reduce dust leakage. The soft transparent sealing plate 5 is made of 1.5mm thick polyvinyl chloride (PVC) material and has self-rebound characteristics, which can quickly seal the inlet and outlet after the workpiece is removed or placed. The edge of the arched hole 6 is embedded with an elastic silicone sealing ring. The inner diameter of the sealing ring can adaptively shrink with the diameter of the operator's arm to form a tight sealing structure.

[0026] The transparent polishing frame 4 is fitted with a sealing strip 8 at the position where it adheres to the surface of the hollow vertical plate 2. The bottom of the transparent polishing frame 4 is sealed and fitted to the surface of the polishing platform 1, forming a polishing space 9 between it and the hollow vertical plate. The bottom opening 20 at the front end of the transparent polishing frame 4 is sealed by a soft transparent sealing plate 5. The sealing strip 8 is made of silicone rubber with a trapezoidal cross-section and a compression rate of 30%, ensuring the sealing performance between the transparent polishing frame 4, the hollow vertical plate 2, and the polishing platform 1. The net size of the polishing space 9 can meet the polishing operation space requirements of conventional plastic rearview mirror housing workpieces.

[0027] The dust collection and filtration mechanism 7 includes a dust collection hood 10 disposed on one side of the bottom of the hollow vertical plate 2. An industrial vacuum cleaner 11 is connected to the other side of the dust collection hood 10, and the outlet of the industrial vacuum cleaner 11 is connected via a pipe to one side of a filter 12 disposed on the upper side of the hollow vertical plate 2. The dust collection port of the dust collection hood 10 is funnel-shaped with an opening size of 200mm × 150mm, and the internal guide plate is inclined at 30° to optimize airflow. The rated airflow of the industrial vacuum cleaner 11 is 1500m³ / h. 3 / h; The filter 12 adopts a three-stage filtration structure, consisting of a primary filter screen (filtration accuracy 5μm), a medium-efficiency filter bag (filtration accuracy 1μm), and a high-efficiency filter element (filtration efficiency ≥99.97%@0.3μm). The air outlet pipe at the upper end of the filter 12 is connected to the air pipe that discharges to the outside. One side of the filter 12 is provided with a sealing door plate that extends through to the outside of the hollow vertical plate 2 to facilitate the disassembly of the filter element.

[0028] The dust suction port of the dust suction hood 10 extends to the outside of the hollow vertical plate 2 and is located within the enclosed polishing space 9 to adsorb dust. A monitoring sensor 13 for detecting dust concentration is located at the top of the interior of the polishing space 9; the monitoring sensor 13 is a laser dust sensor with a detection range of 0-100 mg / m³. 3 The detection accuracy is ±5%, and the dust concentration data is transmitted to the PLC control panel 19 in real time to adjust the dust suction power.

[0029] The polishing platform 1 has polishing power supplies 14 on both sides of its bottom, and each polishing power supply 14 is electrically connected to a polishing machine body 15 for manually polishing plastic rearview mirror housing workpieces in the polishing space 9 via wires; the polishing power supply 14 is a dual-channel independent output power supply with a single-channel rated power of 2000W and an output voltage of 220V±10%; the polishing machine body 15 is equipped with a speed adjustment knob (adjustment range 1000-3000rpm), and the handle is equipped with a non-slip rubber sleeve to improve operating comfort.

[0030] The polishing platform 1 has through holes 16 on both sides of its end, and elastic sealing sleeves 17 are provided inside the through holes 16. The wires of the polishing machine body 15 pass through the through holes 16 into the polishing space 9 and are sealed by the elastic sealing sleeves 17, so that the polishing machine body 15 works within the transparent polishing frame 4. The through holes 16 have a diameter of 20mm, and the elastic sealing sleeves 17 are made of flame-retardant silicone material with an IP65 protection rating. They can tightly wrap wires with a diameter of 10-15mm to prevent dust and moisture from entering.

[0031] A lighting panel 18 is installed on one side of the hollow vertical plate 2 via a suspended plate to ensure that the plastic rearview mirror housing is polished in bright light. The lighting panel 18 is an LED strip light source with a total power of 40W, an illuminance of ≥800lux, and a color temperature of 5500K. It is evenly distributed on the surface of the suspended plate and achieves shadow-free lighting in the polishing space 9 through diffuse reflection. A PLC control panel 19 for controlling the suction power of the dust collection and filtration mechanism 7 is provided on one side of the hollow vertical plate 2. The PLC control panel 19 integrates a 7-inch touch screen, which can display parameters such as real-time dust concentration, vacuum cleaner operating power, and filter pressure difference. It supports switching between manual and automatic modes: in manual mode, the vacuum cleaner power can be adjusted by a knob (adjustment range 30%~100%), and in automatic mode, the optimal suction power is intelligently matched based on the data from the monitoring sensor 13. It also has overload protection and fault alarm functions.

[0032] Specifically, during use, the operator can pick up and put down the workpiece through the pick-up and put-down operation port 20 on one side of the transparent polished protective frame 4. This operation port is sealed from the outside by a soft transparent sealing plate 5.

[0033] During part retrieval, the operator's hand enters the polishing space 9 through the arched hole 6. The elastic material (such as silicone) at the edge of the arched hole fits tightly against the arm, forming a dynamic seal. At this time, the industrial vacuum cleaner 11 continues to operate, creating an inward airflow near the operating port to prevent dust from spilling out.

[0034] After the part is placed, the soft transparent sealing plate 5 automatically rebounds due to its own elasticity, completely covering the outside of the pick-up and put-down operation port 20. Furthermore, due to the inward suction force generated during dust collection, it adheres to the outer surface of the pick-up and put-down operation port 20, thus ensuring the sealing of the polishing space 9.

[0035] A small amount of dust that may be generated during the workpiece handling process is quickly sucked away by the negative pressure of the dust hood 10. The dust hood 10 is located diagonally above the operating port, forming an angle of approximately 45° with the workpiece handling path, ensuring that the airflow effectively covers the operating area. Furthermore, the monitoring sensor 13 detects the dust concentration near the operating port in real time. If the concentration abnormally increases, the PLC control panel 19 automatically increases the vacuum cleaner's power to enhance the suction effect.

[0036] When the operator uses the polishing machine body 15 to grind the workpiece in the polishing space 9, the generated dust is immediately captured by the dust suction hood 10. The dust suction hood has an arc-shaped design, covering the entire polishing work area, and the suction airflow is high.

[0037] Dust enters the industrial vacuum cleaner 11 through the dust hood 10. Large dust particles (>50μm) are first separated by gravity settling, and then finely filtered by the filter 12. The filter is made of membrane-coated polyester fiber material, with a filtration efficiency of ≥99.97% for 0.3μm dust.

[0038] The lighting panel 18 uses LED strip light sources, evenly distributed along the sides of the hollow vertical plate 2, providing uniform illumination of 800-1000 lux. After being reflected by the transparent polished protective frame 4, the light forms a shadow-free operating area on the workpiece surface.

[0039] Operators can adjust the suction power through the PLC control panel 19, dynamically adjusting it according to the polishing intensity: set the high suction mode for coarse polishing (high dust volume) and switch to the low noise mode for fine polishing (low dust volume), so as to control the noise below 75dB.

[0040] The elastic sealing sleeve 17 ensures the sealing of the polishing machine's wiring, preventing dust from entering the electrical system. At the same time, the wiring uses highly flexible cables to accommodate the needs of operators who frequently move the polishing machine.

[0041] When the monitoring sensor 13 detects that the dust concentration continues to exceed the safety threshold, the PLC control panel 19 automatically triggers an audible and visual alarm and gradually increases the vacuum cleaner power to the maximum value within 10 seconds to ensure the safety of the operator.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
