Description

Technical Field

[0001] This utility model relates to the field of plastic product manufacturing technology, and specifically discloses a grinding device with a debris collection function for plastic product manufacturing. Background Technology

[0002] Grinding is an important process in the production of plastic products. However, existing grinding equipment for plastic products has many shortcomings, which seriously affect production efficiency, product quality and working environment.

[0003] First, there are significant deficiencies in the collection of debris and dust. Most traditional grinding equipment lacks effective collection measures, resulting in a large amount of debris and dust being generated during the grinding process, which not only seriously pollutes the working environment and deteriorates the air quality in the workshop, but also poses a great threat to the health of operators. Long-term exposure to such an environment can easily lead to occupational diseases such as respiratory illnesses. Furthermore, this scattered debris and dust may also enter other components of the grinding equipment, leading to accelerated wear, shortening the equipment's lifespan, and increasing maintenance costs.

[0004] Secondly, the dust removal devices in traditional grinding equipment also have many problems. The filter cartridges of some dust removal devices are inconvenient to clean, making it difficult to effectively remove dust and other impurities adhering to them. Over time, the filtration performance of the filter cartridges gradually declines, failing to meet the requirements for efficient dust removal and thus affecting the normal operation of the entire grinding equipment. Furthermore, some filter cartridges have low filtration precision and efficiency, failing to adequately filter pollutants in the air, resulting in the exhaust air still containing a significant amount of dust and other impurities, which does not meet environmental protection requirements.

[0005] In conclusion, there is an urgent need to develop a new type of grinding device for the production of plastic products to solve the above problems. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0029] Please see Figure 1-5 A grinding device with a debris collection function for the production of plastic products includes: an operating table 1, a dust collection hood 2 with an open front end on the top of the operating table 1, and a pair of dust suction hoods 3 embedded in the left and right inner side walls of the dust collection hood 2.

[0030] Dust removal device 4 is located behind the operating table 1. Dust removal device 4 includes dust removal cylinder 5, sealing cover 6, filter cylinder 7 and air pump 8. The bottom of dust removal cylinder 5 is provided with a sewage pipe 9. The top of dust removal cylinder 5 is detachably connected to sealing cover 6 through a flange. The lower end of filter cylinder 7 is closed. Filter cylinder 7 is coaxially arranged inside dust removal cylinder 5 and its upper end is detachably connected to sealing cover 6. The input end of air pump 8 is connected to filter cylinder 7 through a pipe that passes through sealing cover 6. Dust removal cylinder 5 is provided with connecting pipes 10 on both sides that are connected to two dust suction hoods 3.

[0031] The rinsing assembly includes a rinsing pipe 11 coaxially rotatably disposed inside the filter cartridge 7. The lower end of the rinsing pipe 11 is closed and several rinsing nozzles 12 are arranged circumferentially. The open end of the rinsing pipe 11 passes through the sealing cover 6 and is connected to a universal joint 13. The sealing cover 6 is provided with a water supply pump 14 and a drive mechanism for driving the rinsing pipe 11 to rotate. The water supply pump 14 is connected to the other end of the universal joint 13 through a pipe.

[0032] A height-adjustable grinding mechanism is located at the top of the dust collection hood 2;

[0033] The clamping mechanism is located below the grinding mechanism.

[0034] In this embodiment: the plastic product is placed on the storage seat 26, and the bidirectional screw 29 is rotated by rotating the handle, causing the slide 30 to move the clamping member 31 towards each other, clamping the plastic product; if multi-angle grinding of the plastic product is required, the rotary motor 27 can be started to rotate the storage seat 26; the electric push rod 22 is started, and the height of the lifting seat 23 is adjusted according to the size of the plastic product and the grinding requirements, so that the grinding head 25 reaches the appropriate working position; the grinding motor 24 is started, and the grinding motor 24 drives the grinding head 25 to rotate, performing the grinding operation on the plastic product; during the grinding process, the generated debris and dust are collected by the dust collection hood 2, and discharged through the dust suction hood 3 and the connecting pipe 10. The air is conveyed into the dust collection cylinder 5 and filtered by the filter cylinder 7. The filtered air is discharged, while dust and other impurities remain outside the filter cylinder 7. When the filter cylinder 7 needs to be cleaned, the water supply pump 14 is started to supply water to the flushing pipe 11 through the universal joint 13. At the same time, the drive motor 15 of the drive mechanism is started. The drive motor 15 drives the conical drive wheel 16 to rotate, which in turn drives the conical driven wheel 17, which is fixedly connected to the flushing pipe 11, to rotate. This causes the flushing pipe 11 to rotate inside the filter cylinder 7. The flushing nozzle 12 sprays water to flush the filter cylinder 7 from all directions. The filtered debris, dust, and the flushed wastewater are discharged together through the drain pipe 9, achieving the effect of quickly cleaning the filter cylinder 7 and removing debris and dust.

[0035] As a technical optimization of this utility model, the drive mechanism includes a drive motor 15 located on the top of the sealing cover 6, a conical drive wheel 16 located at the output end of the drive motor 15, and a conical driven wheel 17 located on the outer circumference of the flushing pipe 11 and meshing with the conical drive wheel 16.

[0036] In this embodiment: the drive motor 15 drives the conical drive wheel 16 and the conical driven wheel 17 to provide rotational power to the flushing pipe 11, so that the flushing pipe 11 rotates inside the filter cylinder 7, and the filter cylinder 7 is flushed in all directions through the flushing nozzle 12, thereby improving the flushing effect, ensuring the cleanliness of the filter cylinder 7, and thus ensuring the normal operation of the dust removal device 4 and a good dust removal effect.

[0037] As a technical optimization of this utility model, the filter cartridge 7 adopts a three-layer composite structure, consisting of a stainless steel sintered mesh 18, a glass fiber felt 19, and a PTFE membrane 20 from the outside to the inside.

[0038] In this embodiment, the multi-layer filter cartridge 7 formed by the stainless steel sintered mesh 18, glass fiber felt 19 and PTFE membrane 20 can more effectively filter dust and debris and other impurities in the air, improve filtration accuracy and efficiency, extend the service life of the filter cartridge 7, and at the same time reduce the pollutant content in the exhaust air and protect the environment.

[0039] As a technical optimization of this utility model, a transparent observation window 21 is embedded on the front of the dust collector 5, and the transparent observation window extends axially to 2 / 3 of the height of the cylinder.

[0040] In this embodiment, the transparent observation window 21 extends axially to 2 / 3 of the height of the cylinder, which facilitates the operator to observe the dust accumulation inside the dust collector 5, understand the working status of the filter cylinder 7 and whether it needs to be cleaned, and improve the convenience and timeliness of equipment maintenance.

[0041] As a technical optimization of this utility model, the grinding mechanism includes an electric push rod 22 vertically installed at the top inside the dust collection hood 2, a lifting seat 23 located at the output end of the electric push rod 22, a grinding motor 24 located at the bottom of the lifting seat 23, and a grinding head 25 connected to the output shaft of the grinding motor 24 via a quick-change interface.

[0042] In this embodiment: Activating the electric push rod 22 can adjust the height of the lifting seat 23, thereby adjusting the working height of the grinding head 25 to meet the grinding needs of plastic products of different sizes and shapes; the grinding motor 24 drives the grinding head 25 to rotate, realizing the grinding operation of plastic products.

[0043] As a technical optimization of this utility model, the clamping mechanism includes a storage seat 26 and a rotary motor 27 fixedly connected to the bottom of the storage seat 26 at the bottom of the operating table 1. The top of the storage seat 26 has a sliding groove 28, and the sliding groove 28 is provided with a bidirectional screw 29 and two slides 30. The two ends of the bidirectional screw 29 pass through the slides 30 and are rotatably connected to the sliding groove 28. A handle fixedly connected to one end of the bidirectional screw 29 is provided on one side of the storage seat 26. Two clamping members 31 fixedly connected to the top of the slides 30 are provided on the storage seat 26.

[0044] In this embodiment: the storage seat 26 provides a platform for placing plastic products. The bidirectional screw 29 and the slide 30 cooperate to adjust the position of the slide 30 by rotating the handle, thereby clamping or releasing the plastic products. Starting the rotary motor 27 can drive the storage seat 26 to rotate, allowing the plastic products to rotate at multiple angles, which is convenient for polishing different parts.

[0045] As a technical optimization of this utility model, the clamping surface of the clamping member 31 is provided with a rubber pad 32 with anti-slip texture.

[0046] In this embodiment, the rubber pad 32 increases the friction between the rubber pad and the plastic product, preventing the plastic product from sliding during the polishing process. At the same time, the rubber pad 32 has a certain degree of elasticity, which can protect the surface of the plastic product from being pinched and improve the stability of the polishing operation and the product quality.

[0047] Working principle and usage process of this utility model:

[0048] Place the plastic product on the base 26, and adjust the double-ended screw 29 by rotating the handle to clamp the plastic product with the clamping part 31. The rubber pad 32 ensures stable clamping. Connect the power supply and start the electric push rod 22 to adjust the height of the grinding head 25. Start the grinding motor 24 to rotate the grinding head 25 and grind the plastic product. Start the rotary motor 27 (if necessary) to rotate the plastic product at multiple angles to complete the full grinding. During the grinding process, start the air pump 8, and the dust collection hood 2 collects debris and dust. The dust-laden gas enters the filter cartridge 7, and the dust... The air is filtered and purified by the filter cartridge 7, and the dust falls into the bottom or outer wall of the dust collector 5. When the dust accumulates in the filter cartridge 7 and affects the filtration effect, the drain pipe 9 is opened first. After the dust at the bottom of the dust collector 5 is cleaned, the water supply pump 14 and the drive motor 15 of the drive mechanism are started. The flushing pipe 11 rotates in the filter cartridge 7, and the flushing nozzle 12 flushes the filter cartridge 7. The sewage is discharged through the drain pipe 9, thus achieving the cleaning effect of the filter cartridge 7. After the polishing is completed, the drive motor 15, electric push rod 22, rotary motor 27 and other equipment are turned off.
