Description

Technical Field

[0001] The utility model relates to the technical field of plastic polishing, in particular to an engineering plastic part polishing device with a dust collection function. Background Art

[0002] Engineering plastics refer to industrial plastic products used as industrial parts or casing materials. They usually have excellent strength, impact resistance, heat resistance, hardness and aging resistance. For example, polyethylene terephthalate (PET) and polyester carbonate (PC) are widely used in bottle caps, fibers, electronic components and other fields; PC is often used in the manufacture of optical mechanical parts, safety glasses, etc. due to its excellent transparency, heat resistance and electrical insulation.

[0003] At present, engineering plastic parts need to be polished during processing, and plastic products will inevitably generate a lot of dust during the polishing process, which is harmful to the environment and personnel health. Therefore, most of the existing polishing equipment will be equipped with relevant dust collection structures to increase environmental protection. According to research, the dust collection structure that is more common with various polishing devices is a fan with a collection bin. After the dust is sucked into the collection bin, it is intercepted and filtered by the filter. For example, patent No. CN207519736U discloses a shoe polishing fixing device with a dust collection function. This design avoids dust overflow. However, this collection method has certain shortcomings. When dust accumulates on the surface of the filter, the filter needs to be manually removed for processing. This processing method is inconvenient and very time-consuming. It is also easy to cause dust to fly when the filter is removed, and even the filter may fall without attention, causing dust to scatter.

[0004] Therefore, the applicant proposed an engineering plastic part grinding device with a dust collection function to solve the problem. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] Depend on Figures 1-8 The utility model provides an engineering plastic part grinding device with a dust collection function, comprising a grinding table 1 and a collection box 2 located at the bottom thereof. The bottom surface of the grinding table 1 is provided with a dust exhaust hole connected to a workpiece placement groove. The placement groove and the dust exhaust hole are both existing design means. The bottom of the collection box 2 is filled with clean water. The ventilation pipe on the top of the collection box 2 is connected to the bottom of the grinding table 1 and the dust exhaust hole is covered inside. The inner wall of the collection box 2 is rotated to connect the inclined filter plate 22. A fan 21 is installed at the internal opening of the collection box 2, and the fan 21 is located at the inclined upper end of the filter plate 22. On one side, a supporting component 3 is installed on the inner wall of the collecting box 2. The supporting component 3 includes a screw 31 that is threadedly inserted into the threaded hole on the side of the collecting box 2. The screw 31 is located at the inner end of the collecting box 2 and is rotatably connected to a movable plate 32. The movable plate 32 is slidably connected to the inner wall of the collecting box 2, and one side of the movable plate 32 is rotatably connected to a supporting roller 33. The supporting roller 33 contacts the solid part of the bottom of the filter plate 22. A sealing block 24 is fixed to the inner side of the collecting box 2. The bottom surface of the sealing block 24 is fitted with the horizontal part of the lower end of the inclined surface of the filter plate 22, and the top surface of the sealing block 24 is designed to be inclined.

[0029] By designing the support component 3, during processing, the engineering plastic parts are placed in the workpiece placement slot on the top of the grinding table 1 for grinding. During the processing, dust will be generated. At this time, the fan 21 is started and enters the interior through the dust exhaust hole and the ventilation pipe to be collected. The air flow passes through the filter plate 22, and the dust is intercepted by the mesh surface of the filter plate 22. After each processing, the plastic accumulates at the lower end of the inclined surface of the filter plate 22 and is intercepted by the blocking block 24. The top of the blocking block 24 is designed with a slope, and the dust falling on its surface will also slide down. It should be noted that the mesh surface is designed in the opening of the filter plate 22, and a design means is provided, and the mesh surface is close to the inclined lower end of the filter plate 22, and the ventilation pipe outlet is located at the inclined upper end of the mesh surface. At the same time, the filter plate 22 is supported by the support roller 33. Then, after a certain number of engineering plastic parts have been processed, the screw 31 is rotated to move it toward the outside of the collection box 2, so that the movable plate 32 slides, and then the support roller 33 The position of the filter plate 22 changes, and the support roller 33 also rolls on the bottom surface of the filter plate 22. Due to the change in the support position, the support point is closer to the rotation connection point between the filter plate 22 and the collection box 2, which makes the filter plate 22 rotate downward, so that a gap is formed between the lower end of the inclined surface and the blocking block 24. Then the dust can slide down from this gap together, fall into the clean water below, and dissolve in it. Finally, when there is a lot of dust in the water in one day, the sewage can be discharged at one time, so there is no need to take out the filter screen to treat the dust. In this way, there is no need to frequently take out the filter screen for cleaning, and the treatment effect is good, and dust will not overflow during treatment. It should be noted that the opening should not be too large to avoid the dust from sliding down all at once and causing it to fly. At the same time, when the filter plate 22 is opened, the water surface at its bottom is relatively strong, which can cooperate with the stirring of the clean water at the falling water position, and the dust that falls into the water surface can quickly sink to the bottom, so there is basically no flying of dust during the dust entering the water.

[0030] A telescopic rod 34 is fixed to one side of the movable plate 32. The telescopic rod 34 passes through an opening on one side of the cylindrical rod 35 and slides in the hole. When the telescopic rod 34 slides and retracts into the innermost end of the cylindrical rod 35, the bottom end of the inclined surface of the filter plate 22 is close to the water surface.

[0031] The design of the two telescopic rods 34 and the cylindrical rod 35 makes the support and sliding of the movable plate 32 more stable, and can play a limiting effect, preventing the filter plate 22 from rotating too much and causing the lower end of the inclined surface to come into contact with the water surface and stick to it.

[0032] A sealing plate 23 is fixed to the top and side walls of the collecting box 2. The bottom of the sealing plate 23 is designed with a slope and contacts the solid part of the top of the filter plate 22. The mesh surface of the filter plate 22 is designed to seal the lower end of the slope on one side of the sealing plate 23. Inclined sealing strips 25 are fixed on both sides of the inside. The two ends of the sealing strip 25 are docked with the sealing block 24 and the sealing plate 23, and the sealing strip 25 is also in contact with the top surface of the filter plate 22. The sealing strip 25, the sealing block 24 and the sealing plate 23 surround the mesh surface of the filter plate 22 inside, and the sealing strip 25, the sealing block 24 and the sealing plate 23 are provided with a sealing gasket 26 on the bottom surface.

[0033] By designing the sealing plate 23 and the sealing strip 25, when the filter plate 22 contacts the sealing block 24, its two sides and the upper end of the inclined surface can be further limited, and the dust can be concentrated and fall on the mesh surface. The sealing strip 25, the sealing block 24 and the sealing plate 23 surround the four sides of the mesh surface into a closed space, avoiding the overflow of a small amount of dust due to the gap between the movable design of the filter plate 22 and the inner wall of the collection box 2. At the same time, the sealing gasket 26 enhances the sealing performance, which is very practical.

[0034] A stirring rod 211 is rotatably installed inside the collection box 2. The stirring rod 211 is located below the water surface and below the blocking block 24. A motor is installed on one side of the collection box 2 to drive the stirring rod 211 to rotate.

[0035] By designing the stirring rod 211, each time dust is introduced into the water, the motor is started to drive the stirring rod 211 to rotate, so that the position where the dust falls into the water will flow, which is more conducive to the dust being quickly dissolved in the water instead of accumulating and flying on the water surface.

[0036] An inclined block 29 is installed at the bottom end of the collecting box 2, and the stirring rod 211 is located at the upper end of the inclined surface of the inclined block 29. A drainage pipe 210 is provided on one side of the collecting box 2, and the drainage pipe 210 is located on the lower end side of the inclined surface of the inclined block 29.

[0037] By designing the inclined block 29, the dust that settles to the bottom after being stirred by the stirring rod 211 falls on the inclined surface of the inclined block 29 and can slide down and accumulate at the bottom. It can be discharged through the drain pipe 210 to avoid internal residue. The dust will stay away from the stirring rod 211, thereby avoiding being brought up during stirring.

[0038] A water pipe 27 runs through one side of the collection box 2. The water pipe 27 is located above the filter plate 22 and on the side of the upper end of the inclined surface of the filter plate 22. The water pipe 27 is located at the inner end of the collection box 2 and is connected to a diversion pipe 28. Several nozzles are provided on one side of the diversion pipe 28.

[0039] By designing the water pipe 27, after each sewage discharge, the water pipe 27 can be connected to tap water. After the tap water enters the water pipe 27, it is sprayed out from the diversion pipe 28. At this time, the filter plate 22 rotates downward to form a gap between the blocking block 24. Then, the clean water flowing through the mesh surface will wash away a small amount of residual sticky impurities, and after flowing to the surface of the inclined block 29, it will flow down along the inclined surface and finally be discharged from the drain pipe 210. The inclined block 29 and the stirring rod 211 can be flushed at the same time. During flushing, the stirring rod 211 can be rotated to avoid adsorptive impurities remaining on the surface, which is very convenient.

[0040] Working principle: First, the engineering plastic parts are placed in the workpiece placement slot on the top of the grinding table 1 for grinding, and at the same time, the fan 21 is started to suck air through the dust exhaust hole and the ventilation pipe (note that there is a closable grinding chamber on the top of the grinding table 1, which is an existing design and dust will not escape). The air flow passes through the filter plate 22, and the dust is intercepted by the mesh surface of the filter plate 22. After a certain number of engineering plastic parts are processed, the motor is started to drive the stirring rod 211 to rotate, so that the dust falls into the water and flows, and the screw 31 is rotated to move it toward the outside of the collection box 2, so that the moving plate 32 slides and displaces, thereby changing the position of the supporting roller 33, causing the filter plate 22 to rotate downward, and then a gap is formed between the lower end of the inclined surface and the blocking block 24, so that the dust can slide down from the gap together, fall into the clean water below and dissolve in it, and the dust that settles to the bottom falls on the inclined surface of the inclined block 29 and can slide down and accumulate at the bottom. Finally, the sewage can be discharged centrally by opening the drain pipe 210 valve. At the same time, the internal cleaning can be carried out through the water pipe 27 according to the working time. Note that there is a gap between the lower end of the filter plate 22 and the blocking block 24 during cleaning.
