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. Example 1
[0020] Please see Figure 1-4 The present invention provides the following technical solution: a sandblasting machine for surface treatment of precious metals, including a base plate 1, a dust collection box assembly 5 is arranged above the base plate 1, the base plate 1 and the dust collection box assembly 5 are connected by a support frame 3, a sand storage assembly 7 is fixedly installed above the base plate 1 and on one side of the support frame 3, a sand blasting pipe 6 is fixedly installed above the sand storage assembly 7, an adjustment clamping device 2 is fixedly connected to the center of the support frame 3, and an auxiliary cleaning device 4 is fixedly connected to the edge of the dust collection box assembly 5 away from the sand blasting pipe 6.
[0021] Specifically, the positioning clamping device 2 includes an electric lifting rod 21, a protective shell 22, a rotating plate 23, clamping components 24, and a reduction motor 25. The electric lifting rod 21 is fixedly connected to the center of the support frame 3. The protective shell 22 is fixedly connected above the electric lifting rod 21. The reduction motor 25 is fixedly installed inside the protective shell 22. The rotating plate 23 is fixedly installed above the output end of the reduction motor 25. Two clamping components 24 are fixedly installed above the rotating plate 23.
[0022] By adopting the above technical solution, workers can adjust the angle and height of the precious metal to be processed by means of the electric lifting rod 21 and the geared motor 25 when needed, so as to perform sandblasting treatment on different positions.
[0023] Specifically, the clamping assembly 24 includes a protective frame 242 and a first electric telescopic rod 243. The first electric telescopic rod 243 is fixedly installed above the rotating plate 23, and the protective frame 242 is fixedly installed on the outside of the first electric telescopic rod 243.
[0024] By adopting the above technical solution, workers can fix the precious metal to be processed when needed by using the first electric telescopic rod 243 and other structures, thereby preventing the precious metal to be processed from moving accidentally during the work process.
[0025] Specifically, the clamping assembly 24 also includes a rubber layer 241, and the rubber layer 241 is fixedly connected to both adjacent sides of the two protective frames 242.
[0026] By adopting the above technical solution, the sandblasting machine can ensure the friction between the protective frame 242 and the precious metal to be processed through the rubber layer 241, thereby ensuring the normal operation of the clamping work and better meeting the needs of the work.
[0027] In this embodiment, when sandblasting is required to process the surface of precious metals, the dust collection box assembly 5 is opened, and the operator places the precious metal between the rubber layers 241 in the two clamping components 24 of the adjusting clamping device 2. Then, the two first electric telescopic rods 243 are activated, thereby moving the two protective frames 242 and clamping the precious metal with the two rubber layers 241. Then, the reduction motor 25 in the protective shell 22 is activated, thereby rotating the rotating plate 23 and other structures to adjust the angle of the precious metal. Then, the electric lifting rod 21 is activated, thereby raising and lowering the protective shell 22 and other structures to adjust the height of the precious metal. Then, the operator closes the dust collection box assembly 5 and activates the sand storage assembly 7 on the bottom plate 1. The sand storage assembly 7 sends sand into the sandblasting pipe 6, and then the sand is sprayed onto the precious metal for sandblasting. After processing, the sand storage assembly 7 is closed. The support frame 3 provides support. Example 2
[0028] The difference between this embodiment and embodiment 1 is that the auxiliary cleaning device 4 includes a second electric telescopic rod 41, a movable plate 42, a fan 44, a movable box 45, and an air outlet net 46. The second electric telescopic rod 41 is fixedly connected to the side of the dust collection box assembly 5 away from the sandblasting pipe 6. The movable plate 42 is fixedly connected to the side of the second electric telescopic rod 41 away from the dust collection box assembly 5. The movable box 45 is fixedly connected above the movable plate 42. Multiple fans 44 are fixedly connected to the side of the movable box 45 away from the dust collection box assembly 5. The air outlet net 46 is fixedly connected to the bottom of the movable box 45.
[0029] By adopting the above technical solution, workers can clean the sand particles remaining on the surface of precious metals after processing by using the cooperation of structures such as the fan 44 and the air outlet 46 when needed, thereby reducing the difficulty of the cleaning work and alleviating the workload of the workers.
[0030] Specifically, the auxiliary cleaning device 4 also includes a screen 43, which is fixedly connected to the side of the fan 44 away from the moving box 45.
[0031] By adopting the above technical solution, staff can prevent external impurities from entering the interior of the fan 44 when needed through the screen 43, thereby preventing external impurities from having an adverse effect on the fan 44 and other structures.
[0032] In this embodiment, when it is necessary to clean the sand particles remaining on the surface of the precious metal after processing, the worker activates the second electric telescopic rod 41 in the auxiliary cleaning device 4, thereby moving the moving plate 42 and the moving box 45 and other structures, thereby moving the air outlet net 46 back and forth above the precious metal, activating each fan 44, and sending the air filtered by the partition net 43 into the moving box 45, and then the air is blown from the air outlet net 46 onto the precious metal, thereby blowing away the sand particles on it, and thus carrying out the cleaning work.
[0033] The structure and principle of the dust collector assembly 5 (comprising a dust collector, handle, operating hole, through hole, sand extraction port, filter, operating gloves, observation window, mesh, regulating valve, sand extraction pipe, and exhaust fan), the sand spraying pipe 6, and the sand storage assembly 7 (comprising a sand spraying pump and sand storage tank) in this utility model have been disclosed in a dust collector sandblasting machine disclosed in Chinese Patent Application No. 202120166400.5. Its working principle is that the box door is hinged and has a handle; when ceramic to be ground needs to be placed into the dust collector, the box door is opened, and after placement, the box door is closed, ensuring the ceramic is processed in a separate workshop and preventing sand particles from flying into other workshops; the operating surface of the dust collector has a through hole, and a sand spraying pipe is sealed inside the through hole, the sealing preventing dust from flying into other workshops. Dust escapes from the through-hole; one end of the sandblasting pipe is connected to the sandblasting pump, which is connected to the sand storage tank. The other end of the sandblasting pipe is equipped with a sandblasting head, located inside the dust collection box. Sand particles in the sand storage tank are sucked into the sandblasting pump, which then transports the sand particles to the sandblasting pipe, finally spraying them out from the sandblasting head to grind and polish the ceramic to be polished inside the dust collection box. An operating hole is also provided on the operating surface of the dust collection box, located to one side of the through-hole. An operating glove is fitted inside the operating hole. An observation window is provided on the dust collection box, allowing operators to observe the grinding process inside in real time. By utilizing the through-hole and operating hole on the dust collection box to install the sandblasting pipe and operating glove on the operating surface, the operator puts their hand inside the operating glove and then picks up the sandblasting pipe to perform sandblasting. This separation of workers from the processing workshop ensures that workers are not harmed during sandblasting. The dust collection box has a sand extraction port connected to an exhaust fan via a extraction pipe. The exhaust fan's outlet is connected to a sand storage tank. The exhaust fan continuously extracts sand particles, which are then discharged back into the sand storage tank through the outlet pipe, enabling sand recycling. A filter with numerous mesh openings is installed between the exhaust fan and the sand storage tank. When the sandblasting pipe polishes the ceramic, it removes excess material from the ceramic surface. This excess material is also drawn into the extraction pipe by the exhaust fan. The filter's mesh openings filter this material, preventing large particles from entering the circulation loop and being sprayed. The sand spray from the nozzle abrades the ceramic surface. After a period of use, the filter needs to be replaced. The filter, primarily for filtration, can be purchased commercially. The operating gloves are non-slip gloves to prevent sand particles from falling onto the spray nozzle and causing uneven polishing due to slippage. The spray head is equipped with a regulating valve to adjust the size of the sand outlet. The operator can observe the polishing process in real-time through an observation window and adjust the spray volume using the regulating valve as needed. There are two operating ports on the same horizontal plane. These ports allow operators to choose the appropriate port based on their preferred hand position, improving efficiency.
[0034] The working principle and usage process of this utility model are as follows: When sandblasting is required to process the surface of precious metals, the dust collection box assembly 5 is opened, and the operator places the precious metal between the rubber layers 241 in the two clamping components 24 of the adjusting clamping device 2. Then, the two first electric telescopic rods 243 are activated, thereby moving the two protective frames 242, which in turn causes the two rubber layers 241 to clamp the precious metal. Then, the reduction motor 25 in the protective shell 22 is activated, thereby rotating the rotating plate 23 and other structures to adjust the angle of the precious metal. Then, the electric lifting rod 21 is activated, thereby raising and lowering the protective shell 22 and other structures to adjust the height of the precious metal. Finally, the operator closes the dust collection box assembly 5 and starts the base plate 1. The sand storage component 7 on the upper part sends sand particles into the sandblasting pipe 6, and then the sand particles are sprayed onto the precious metal to perform sandblasting. After the processing is completed, the sand storage component 7 can be turned off. The support frame 3 plays a supporting role. When it is necessary to clean the sand particles remaining on the surface of the precious metal after processing, the staff will start the second electric telescopic rod 41 in the auxiliary cleaning device 4, which will drive the moving plate 42 and the moving box 45 to move, thereby driving the air outlet net 46 to move back and forth above the precious metal. The fans 44 are started, and the fans 44 send the air filtered by the mesh 43 into the moving box 45. Then the air is blown from the air outlet net 46 onto the precious metal to blow away the sand particles, thereby carrying out the cleaning work.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
