[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a sand table model polishing device, comprising a dust suction mechanism 1, the top of which is fixedly connected with a rotating mechanism 2;

[0026] The dust collection mechanism 1 includes a grinding device body 101, the top of the grinding device body 101 is fixedly connected to two dust collection pipes 102, the input ends of the two dust collection pipes 102 are fixedly connected to dust collection covers 103, and the output ends of the two dust collection pipes 102 are fixedly connected to an adsorption box 104, the bottom of the adsorption box 104 is provided with a first ventilation hole 105, the inner surface wall of the first ventilation hole 105 is fixedly inserted with an exhaust fan 106, the bottom of the adsorption box 104 is fixedly connected to a filter box 107, and a first embedded groove 108 is provided on one side of the outer wall of the filter box 107, and an embedded frame 109 is movably inserted into the inner surface wall of the first embedded groove 108, and a filter screen 110 is fixedly connected between the inner surface walls of the embedded frame 109, and the outer wall of the embedded frame 109 is fixedly connected to the outer surface wall of the embedded frame 109. A first handle 111 is fixedly installed on one side, a second embedding groove 112 is opened on one side of the outer wall of the filter box 107, a medium-efficiency filter 113 is movably inserted into the inner wall of the second embedding groove 112, a second handle 114 is fixedly installed on one side of the outer wall of the medium-efficiency filter 113, a second ventilation hole 115 is opened on one side of the outer wall of the filter box 107, a ventilation fan 116 is fixedly inserted into the inner wall of the second ventilation hole 115, two sets of hinges 117 are fixedly installed on the outer wall of the grinding equipment body 101, cabinet doors 118 are fixedly connected between the rotating ends of the two sets of hinges 117, a third handle 119 is fixedly installed on one side of the outer walls of the two cabinet doors 118, and four universal wheels 120 are fixedly installed on the bottom of the grinding equipment body 101.

[0027] The effect achieved by the entire embodiment 1 is that when the grinding equipment body 101 is grinding the sand table model, the exhaust fan 106 is first started. After the exhaust fan 106 is started, negative pressure is generated, so that a low-pressure environment is formed inside the adsorption box 104, thereby prompting the two dust suction pipes 102 to generate suction. This suction acts on the two dust suction hoods 103. Since the two dust suction hoods 103 are located on both sides of the sand table model to be polished, they effectively expand the adsorption range. At this time, the dust and debris generated during the grinding process are captured by the two dust suction hoods 103, and are guided to the adsorption box 104 through the dust suction pipe 102, and then enter the inside of the filter box 107. After the dust enters the filter box 107, the staff starts the ventilation fan 116. The airflow generated by the ventilation fan 116 after starting forms a negative pressure inside the filter box 107, thereby guiding the dust-containing gas to move toward the second ventilation hole 115. During this process, the filter 110 first performs preliminary filtration to intercept larger particles and debris. Subsequently, the gas after preliminary filtration passes through the medium efficiency filter 113, and the medium efficiency filter 113 further captures smaller dust particles, thereby achieving multi-stage filtration. Finally, the filtered clean gas is discharged through the second ventilation hole 115, thereby ensuring the cleanliness of the polishing site and the health of the operators.

[0028] Embodiment 2, as Figure 2-Figure 4 As shown, the rotating mechanism 2 includes two first bearing seats 201, a rotating rod 202 is fixedly inserted between the inner walls of the two first bearing seats 201, a worm wheel 203 is fixedly sleeved on the outer wall of the rotating rod 202, a worm 204 is meshingly connected to the outer wall of the worm wheel 203, a self-locking motor 205 is fixedly connected to one side of the outer wall of the worm 204, two second bearing seats 206 are fixedly sleeved on the outer wall of the worm 204, the outer wall of the rotating rod 202 is fixedly connected to a support plate 207, two cylinders 208 are fixedly installed on the top of the support plate 207, and the telescopic ends of the two cylinders 208 are fixedly connected to a clamping plate 209, the top of the grinding equipment body 101 is fixedly connected to the bottom of the two first bearing seats 201, the top of the grinding equipment body 101 is fixedly connected to the bottom of the two second bearing seats 206, and the top of the grinding equipment body 101 is fixedly connected to the bottom of the self-locking motor 205.

[0029] The effect achieved by the entire embodiment 2 is that when the sand table model needs to be polished, it is first placed on the top of the support plate 207, and then the two cylinders 208 are started. The telescopic ends of the two cylinders 208 will respectively drive the two clamps 209 to clamp and fix the sand table model to ensure that the model remains stable during the polishing process. When the side or other specific positions of the sand table model need to be polished, the self-locking motor 205 is first started, and the output end of the self-locking motor 205 will drive the worm 204 to rotate. Through the transmission mechanism of the worm gear 203 and the worm gear 204, the worm gear 203 starts to rotate. The rotation of the worm gear 203 further drives the rotating rod 202 to rotate, and the rotating rod 202 drives the support plate 207 and the sand table model to rotate synchronously, thereby adjusting the direction or angle of the sand table model. In this way, the sand table model can be rotated at multiple angles in the horizontal plane, thereby exposing the side or other parts that need to be polished, so as to facilitate the precise operation of the polishing equipment.

[0030] Working principle: When the equipment is powered on and ready, the operator first places the sand table model accurately on the top of the support plate 207, and then starts the two cylinders 208. The telescopic ends of the two cylinders 208 will respectively drive the two clamping plates 209 to firmly clamp and fix the sand table model to ensure that the position of the sand table model is stable and will not shift during the grinding process. When the grinding equipment body 101 starts the grinding operation, the operator needs to start the exhaust fan 106 and the ventilation fan 116 at the same time. After the exhaust fan 106 is started, the high-speed rotation of the impeller will generate a strong airflow, which will form a negative pressure environment inside the adsorption box 104. Due to the negative pressure Due to the presence of the two dust suction pipes 102, a strong suction force will be generated in the two dust suction pipes 102, and this suction force will be effectively transmitted to the two dust suction hoods 103. The design of the dust suction hoods 103 expands the suction range, effectively avoiding the scattering of dust and debris generated during the grinding process, and ensuring a clean working environment. At this time, the dust and debris generated during the grinding process are effectively adsorbed by the two dust suction hoods 103 and enter the filter box 107 through the first ventilation hole 105. At the same time, after the ventilation fan 116 is started, a negative pressure environment is generated inside the filter box 107, which helps to guide the dust-containing gas to move to the second ventilation hole 115. In this process, the filter screen 110 first The dust-laden gas entering the filter box 107 is initially filtered to intercept larger particles and debris. Subsequently, the gas after the initial filtration passes through the medium efficiency filter 113, which further removes smaller dust particles, thereby performing multi-stage filtration on the gas. In order to facilitate the cleaning and replacement of the filter 110 and the medium efficiency filter 113, the operator can open the two cabinet doors 118 respectively by pulling the two third handles 119, and then pull out the embedded frame 109 and the medium efficiency filter 113 by pulling the first handle 111 and the second handle 114, so that the filter 110 and the medium efficiency filter 113 can be cleaned and replaced. When it is necessary to grind the side or other different surfaces of the sand table model, the operator first starts the self-locking motor 205. The output end of the self-locking motor 205 drives the worm 204 to rotate. The rotation of the worm 204 drives the worm wheel 203 to rotate. The rotation of the worm wheel 203 further drives the rotating rod 202 to rotate. The rotation of the rotating rod 202 makes the support plate 207 and the sand table model rotate synchronously, thereby realizing multi-angle grinding of the sand table model. In addition, the transmission mechanism of the worm wheel 203 and the worm 204 has a certain self-locking characteristic. At the same time, the self-locking motor 205 also has a self-locking ability, which ensures that the sand table model can maintain a stable rotation angle during the grinding process.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
