Description

Technical Field

[0001] The invention relates to the technical field of model processing, in particular to a grinding and painting device for an environment design model. Background Art

[0002] In today's environmental design field, model making is a key link to visualize creativity and assist in the implementation of projects. Grinding and painting are important processes in the later stage of model processing, which are related to the final presentation effect and quality of the model. However, traditional model grinding and painting methods are increasingly difficult to meet industry needs, giving rise to new professional grinding and painting devices. With the acceleration of urbanization, various construction projects and landscape planning have sprung up like mushrooms after rain, and the demand for environmental design has exploded. The use of models has become more diverse. Traditional manual grinding and painting relies on the experience and skills of craftsmen, which is inefficient and often takes several days, making it difficult to meet the tight schedule of the project. In addition, uneven manual grinding can easily lead to uneven surface of the model, and it is difficult to unify the thickness and color of the paint, and there are frequent defects in subtle places, which seriously affects the professionalism and display effect of the model.

[0003] Environmental pressure is also an important factor driving change. Traditional grinding and painting are mostly carried out in open spaces, and the large amount of dust and debris generated by grinding are scattered everywhere, polluting the air; organic solvents volatile during painting, such as benzene, toluene, and xylene, are harmful to the health of operators, and long-term inhalation can easily cause respiratory diseases and nervous system damage.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Please refer to the attached Figure 1 -Attached Figure 8 The embodiment of the present invention provides a polishing and painting device for an environmental design model, comprising a support ring 1, a collecting seat 2 is installed at the bottom of the support ring 1, an adapting mechanism is installed at one end of the inner part of the collecting seat 2, which is used to provide a polishing and painting space adapted to the bottom of the model, a cleaning mechanism is installed inside the collecting seat 2, which is used to collect impurities generated by polishing and painting the model, and a protective mechanism is also installed on the top of the collecting seat 2, which is used to isolate the model from the outside world;

[0030] The adapting mechanism includes a slide rail 3, which is mounted on the outer wall of the support ring 1, and a movable seat 4 is slidably connected inside the slide rail 3, one end of a connecting plate 5 is fixedly connected to one side of the outer wall of the movable seat 4, and a pressure wheel 6 is rotatably connected to the other end of the connecting plate 5, a support seat 7 is mounted inside the collecting seat 2, and a plurality of display panels 8 are rotatably connected to the outer wall of the support seat 7, and one end of a tension spring 9 is mounted on the bottom of the plurality of display panels 8, and the other end of the tension spring 9 is fixedly connected to one side of the inner wall of the collecting seat 2, and a rotating component is mounted on one side of the outer wall of the connecting plate 5;

[0031] Specifically, multiple display boards 8 form a supporting body to support the environmental design model. Equipment for polishing and painting the environmental design model can be installed on the top of the moving seat 4. In the initial state, multiple tension springs 9 are perpendicular to the inner bottom wall of the collecting seat 2. When the moving seat 4 inside the slide rail 3 is started, the connecting plate 5 and the pressure wheel 6 are driven to make circular motion. The height of the bottom of the pressure wheel 6 is lower than the height of the display board 8 when it is horizontal. Therefore, the pressure wheel 6 squeezes the display board 8 when making a circular motion, causing one end of the display board 8 to rotate downward with the support seat 7 as the center. At this time, the space corresponding to the bottom of the environmental design model has no support, and the polishing tool can be extended into the bottom of the model to complete polishing and painting. There is no need to manually change the environmental design model, which saves the time required for processing the environmental design model.

[0032] The cleaning mechanism includes an air pump 10, which is installed on one side of the outer wall of the collecting seat 2. An annular channel 11 is installed inside the collecting seat 2. The input end of the air pump 10 is connected to the annular channel 11. The outer wall of the annular channel 11 is equidistantly connected to multiple extraction pipes 12. A baffle 13 is slidably connected to one side of the outer wall of the extraction pipe 12. One end of the baffle 13 is installed with one end of a tension spring 14, and the other end of the tension spring 14 is installed on one side of the outer wall of the extraction pipe 12.

[0033] Specifically, the air pump 10 pneumatically extracts air from the annular channel 11, and the annular channel 11 collects the air inside the collection seat 2 through multiple extraction tubes 12. While the bottom of the environmental design model is polished and painted, the debris generated by the model accumulates inside the collection seat 2. The baffles 13 on the surface of the extraction tubes 12 are slid open to allow the air to flow toward the extraction tubes 12 until the debris flows with the air inside the annular channel 11, thereby completing the collection of the debris generated by polishing and painting the environmental design model.

[0034] The protection mechanism includes an extension channel 15, a through hole 16 is provided at the input end of the extension channel 15, the through hole 16 is connected to the annular channel 11, an annular air bag 17 is connected to the output end of the extension channel 15, one end of a light spring 18 is installed inside the annular air bag 17, the other end of the light spring 18 is installed on the inner wall of the extension channel 15, and a collecting component is installed inside the annular air bag 17;

[0035] The collecting assembly includes a filter plate 1 24, which is mounted at one end of the extension channel 15, and a filter plate 25 is rotatably connected to the other end of the inner wall of the extension channel 15, and an inclined blade 26 is mounted on one side of the outer wall of the filter plate 25, and the filter plate 1 24 fits the filter plate 2 25;

[0036] The collecting assembly further includes a surrounding groove 27, which is disposed inside the extension path 15, and inside the surrounding groove 27 are slidably connected a roller 28 and a filter plate 25 in sequence;

[0037] The through hole 16 is opened at an angle;

[0038] Specifically, the air pump 10 extracts air from the inside of the collecting seat 2 through the extraction pipe 12. After entering the extraction pipe 12, this part of the air flows along the extension path 15 to the inside of the annular airbag 17. As the air continuously fills the inside of the annular airbag 17, the annular airbag 17 is inflated and expanded, and its top gradually rises, forming a protective ring outside the collecting seat 2. During the air flow, the debris generated by grinding and painting is blocked by the filter plate 2 25 and the filter plate 1 24 respectively.

[0039] In addition, while the air is flowing, since the through hole 16 is opened at an angle, the rapidly inclined air flows giving a driving force to the inclined blades 26. Under the action of this driving force, the filter plate 25 rotates, and the debris accumulated on the surface of the filter plate 1 24 and the filter plate 2 25 is shaken off, so that the debris floats again inside the extension channel 15, ensuring the continuous filling of the air inside the annular airbag 17, and also causing the debris to accumulate in the extension channel 15, which is convenient for the subsequent cleaning of the debris.

[0040] The rotating assembly includes an extension rod 19, one end of which is connected to one side of the outer wall of the connecting plate 5, and the other end of the extension rod 19 is fixedly connected to an arc rod 20. Short shafts 21 are installed at both ends of the arc rod 20, and a clamping plate 22 is installed inside the short shaft 21. One end of a spring 23 is installed on one side of the outer wall of the clamping plate 22, and the other end of the spring 23 is installed on the outer wall of the arc rod 20.

[0041] Specifically, the extension rod 19 rotates with the rotation of the connecting plate 5, and the clamping plates 22 at both ends of the arc rod 20 push the protrusions of the outer wall of the baffle 13 during the movement. The spring 23 is squeezed and contracts, so that the baffle 13 and the outer wall of the extraction tube 12 slide relative to each other. Under the extraction of the air pump 10, the debris generated during the grinding process of the environmental design model can be sucked and collected. The arc rod 20 has the same arc length as the display board 8. When one of the display boards 8 is pushed to rotate downward, the extraction tubes 12 on both sides form an efficient airflow loop to the surrounding area of ​​the downward rotating display board 8. The debris generated by the grinding of the environmental design model is extracted, so that the debris generated by the grinding of the environmental design model can be efficiently and quickly extracted and collected. When the corresponding part of the environmental design model is ground, the transfer seat inside the slide rail 3 continues to feed, driving the arc rod 20 to rotate synchronously. At this time, the spring 23 continues to contract under pressure until the clamping plate 22 and the outer wall protrusion of the baffle 13 slide relative to each other and disengage. The spring 23 returns to its original state without the squeezing force outside. Under the continued rotation of the arc rod 20, the other baffles 13 are pushed to form a suction circuit, thereby achieving the integrated grinding and cleaning of the bottom of the environmental design module.

[0042] A rotating shaft 29 is installed on one side of the outer wall of the extension channel 15, and a cleaning plate 30 is installed inside the rotating shaft 29, and one end of the cleaning plate 30 is engaged with the extension channel 15;

[0043] Specifically, by rotating the rotating shaft 29, the cleaning plate 30 can be driven to rotate around the rotating shaft 29 to disengage it from the engagement state with the extension channel 15. At this time, impurities inside the filter plates 1 24 and 25 fall due to gravity and accumulate inside the extension channel 15. The outer wall side of the extension channel 15 is opened by rotating the cleaning plate 30, so that the inside can be cleaned. After the cleaning is completed, the cleaning plate 30 is rotated back to its original position so that it can be re-engaged with the extension channel 15. This not only facilitates the cleaning of key filtering components inside the device, but also ensures that during normal operation, the cleaning plate 30 will not affect the normal flow of airflow in the extension channel 15 and the normal filtering function of the collecting component, which helps to extend the overall service life of the device and maintain the device in good working condition.

[0044] Working principle: When preparing to polish and paint the environmental design model, you must first use the adapter mechanism to build an adaptation space for the model. In the initial state, multiple tension springs 29 are naturally drooping, perpendicular to the inner bottom wall of the collection seat 2, and the display board 8 maintains its initial position under the tension of the tension spring 29, and the moving seat 4 in the slide rail 3 is started. The moving seat 4 begins to slide along the slide rail 3. Since it is fixedly connected to the connecting plate 5, it drives the connecting plate 5 to move together, and then the pressure wheel 6 at the other end of the connecting plate 5 moves accordingly. The design height of the bottom of the pressure wheel 6 is lower than the height of the display board 8 when it is horizontal. As the pressure wheel 6 moves in a circle, it will squeeze the display board 8. After the display board 8 is squeezed, one end rotates downward with the support seat 7 as the center. In this way, the space corresponding to the bottom of the model is vacated, and the polishing tools and painting equipment can smoothly extend into the bottom of the model to carry out operations. There is no need to manually flip or adjust the model during the whole process, which greatly saves the time and labor cost of model processing, ensures that the grinding and painting operations are carried out efficiently and accurately, and adapts to environmental design models of different shapes and sizes. When the grinding and painting process starts, the air pump 10 of the cleaning mechanism starts working. The input end of the air pump 10 is connected to the annular channel 11. When working, the air in the annular channel 11 is pneumatically extracted, causing the internal air pressure of the annular channel 11 to decrease.

[0045] The annular channel 11 collects the air inside the collection seat 2 through multiple extraction pipes 12 connected at equal intervals on the outer wall. Impurities such as debris generated by model grinding and paint mist generated by painting gradually accumulate inside the collection seat 2. When these impurities need to be cleaned, the baffles 13 on the surface of the extraction pipes 12 are slid open respectively. The baffle 13 is originally in a closed state under the tension of the tension spring 14. After sliding open to overcome the tension of the tension spring 14, the air flows rapidly toward the extraction pipe 12 driven by the air pressure difference. The air carrying impurities flows into the annular channel 11 along the extraction pipe 12, completing the collection of debris generated by the grinding and painting of the environmental design model, maintaining the working area relatively clean, preventing impurities from secondary contamination of the model, and also facilitating subsequent equipment maintenance. The air extracted by the air pump 10 flows into the annular airbag 17 along the extension channel 15 after passing through the extraction pipe 12. As the air is continuously filled, the annular airbag 17 is inflated, and its top gradually rises, and finally a protective ring is formed outside the collection seat 2. This protective ring can effectively isolate adverse factors such as dust and moisture from the outside world, isolate the model from the outside environment, create a relatively clean and stable processing environment for the model, and reduce the impact of external interference on the polishing and painting effects. During the air flow, the debris generated by polishing and painting moves forward with the air flow, and encounters filter plate 1 24 and filter plate 2 25 in turn. Filter plate 1 24 first intercepts larger particles of impurities, achieving a preliminary filtering effect; filter plate 2 25 fits tightly with filter plate 1 24 to further block fine impurities.

[0046] Thanks to the inclined opening of the through hole 16, the rapidly inclined air flows to give the inclined blades 26 on the filter plate 25 a driving force, prompting the filter plate 25 to rotate. During the rotation process, the debris accumulated on the surface of the filter plate 1 24 and the filter plate 2 25 is shaken off, so that the debris floats again inside the extension channel 15. This not only ensures the continuous filling of the air inside the annular airbag 17, but also allows the debris to be concentrated and accumulated in the extension channel 15, which is convenient for subsequent centralized cleaning. When the adapter mechanism is in operation, the rotation of the connecting plate 5 will drive the extension rod 19 to rotate synchronously, and the arc rod 20 connected to the other end of the extension rod 19 will move accordingly. The card plates 22 at both ends of the arc rod 20 will touch the protrusions on the outer wall of the baffle 13 during the movement. At this time, the spring 23 is squeezed and contracted by the extrusion force, driving the baffle 13 and the outer wall of the extraction tube 12 to slide relative to each other, and the extraction tube 12 is opened. Under the extraction action of the air pump 10, the debris generated during the grinding process is sucked and collected in time. Moreover, the arc rod 20 has the same arc length as the display board 8. When one of the display boards 8 is pushed to rotate downward, the extraction tubes 12 on both sides thereof form an efficient airflow loop with the help of the linkage of the arc rod 20, which is specifically used to extract the surroundings of the downward rotating display board 8 with great force. The debris generated by the grinding of the environmental design model can be efficiently and quickly extracted and collected. When the corresponding part of the model is polished, the moving seat 4 in the slide rail 3 continues to feed, driving the arc rod 20 to rotate synchronously, and the spring 23 continues to be compressed and contracted until the card plate 22 and the outer wall protrusion of the baffle 13 slide relative to each other and disengage, and the spring 23 returns to its original state. Then, the arc rod 20 continues to rotate, and pushes the other baffles 13 to form a new suction loop, achieving the integrated operation of grinding and cleaning the bottom of the model, and improving the overall processing efficiency. After the device has been used for a period of time, filter plate 1 24 and filter plate 2 25 will intercept a large amount of impurities, affecting the filtering effect and airflow, and need to be cleaned at this time. By rotating the rotating shaft 29, the cleaning plate 30 is driven to rotate around the rotating shaft 29, so that it is out of the engagement state with the extension channel 15. The impurities inside the filter plate 1 24 and the filter plate 2 25 lose their obstruction and fall under the action of gravity, and accumulate inside the extension channel 15. The operator can easily clean the impurities accumulated inside the extension channel 15. After the cleaning is completed, the cleaning plate 30 is turned back to its original position so that it is re-engaged with the extension channel 15. This can not only facilitate the cleaning of key filtering components, but also ensure that during normal operation, the cleaning plate 30 will not interfere with the normal flow of airflow in the extension channel 15 and the normal filtering function of the collection component, thereby maintaining the good operation state of the device and extending the service life of the equipment.
