Description

Technical Field

[0001] This utility model belongs to the field of SiC crystal rod bonding technology, specifically relating to a dust-proof feeding and mixing device for diamond cutting powder. Background Technology

[0002] Announcement No. CN222567630U discloses a dust-proof feeding and mixing device for diamond cutting powder. This fixture mainly relates to the field of SiC crystal rod production and manufacturing processes. The device consists of a handle, a diamond cutting powder placement basket, dustproof gloves, a bottom strainer, a transparent cover, a stirring motor, cutting fluid stirring blades, an openable lid, a drain valve, a cutting fluid tank, a non-openable lid, and support feet for the cutting fluid tank. When preparing the cutting fluid, bagged diamond powder is placed in a basket with a stainless steel mesh at the bottom. Personnel wearing dustproof gloves from the device open the bag of diamond powder and pour the diamond powder through the stainless steel mesh at the bottom of the basket into the mixing fluid for stirring. This prevents waste of diamond powder during the feeding process and avoids dust injury to workers.

[0003] The drawbacks of the above-mentioned patent during use are as follows: the diamond cutting powder particles are extremely fine and light, and they are easy to drift and adhere to the inside of the cover when unpacking. The dust layer will quickly obstruct the view, and the operator will not be able to observe the materials placed in the basket, thus reducing the efficiency of use. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a dust-proof feeding and mixing device for diamond cutting powder, which solves the problem that diamond cutting powder particles are extremely fine and lightweight, and easily adhere to the inside of the cover plate when unpacking, causing the dust layer to quickly obstruct the view, making it impossible for operators to observe the materials in the basket and reducing the efficiency of use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a diamond cutting powder dust-proof feeding and mixing device, comprising a mounting shell, the top surface of which is threadedly connected to the bottom surface of a mounting base, and a sealing gasket is provided at the connection between the mounting shell and the mounting base. A top plate is fixedly provided on the top surface of the mounting base, and an installation window is provided through the center of the top plate. Partition plates are fixedly provided at both ends of the installation window, and a movable groove is left between the partition plates and the inner wall of the end of the installation window. A powder vibrating assembly is provided in the movable groove. The powder vibrating assembly includes a movable plate slidably disposed in the movable groove. The movable plate abuts against a scraping assembly disposed in the mounting base. The scraping assembly includes a lead screw, which is threadedly connected to a slide bar. A rack is fixedly provided on one side of the slide bar, and the rack meshes with a gear. The shaft of the gear is connected to a swing rod, and a scraper is provided on the top surface of the swing rod. The scraper fits against a transparent observation plate disposed in the installation window, and one end of the scraper abuts against one side of the movable plate.

[0006] The beneficial effects of this utility model are: The operator can start the scraping assembly through the controller. The micro motor in the mounting cavity drives the lead screw to rotate, and the slide bar drives the rack to move under the guidance of the limit rod, which in turn drives the gear to rotate. Since the gear shaft is coaxial with the center of the fan-shaped mounting window, the swing rod can drive the scraper to slide along the arc of the observation plate, directly scraping the surface dust layer into the mounting shell and restoring the clarity of observation in real time. At the same time, when the scraper swings, it squeezes the movable plate in the movable groove. The movable plate slides along the arc guide rod and compresses the spring. When the scraper returns to its original position, the spring pushes the movable plate back and generates a slight vibration, shaking off the dust remaining on the surface of the movable plate and in the movable groove.

[0007] In order to understand the internal situation of the device from multiple perspectives: As a further improvement to the above technical solution: the installation window is set in a fan shape, and the center of the mounting base is provided with a fan-shaped through hole corresponding to the installation window, and one end of the partition plate faces the center of the fan-shaped installation window.

[0008] The beneficial effects of this improvement are: the fan-shaped window expands the viewing angle, allowing operators to have a comprehensive view of the device's interior.

[0009] To drive the scraper: As a further improvement to the above technical solution: the mounting base has a movable cavity and a mounting cavity sequentially formed from top to bottom on one side. The movable cavity has a movable window for the swinging rod to swing through the inner wall of the side facing the central through hole of the mounting base. The gear is rotatably mounted on the inner bottom surface of the mounting cavity through a bearing. A micro motor is embedded in the inner wall of one side of the mounting cavity, and the output shaft of the micro motor is connected to one end of a lead screw. A limit rod is provided on one side of the lead screw, and the two ends of the limit rod are connected to the inner walls of the two sides of the mounting cavity. The slide bar is slidably sleeved on the outside of the limit rod.

[0010] The beneficial effects of this improvement are as follows: by driving the lead screw to rotate through a micro motor, and combining this with the limit rod to restrict the movement direction of the slide bar, the slide bar drives the rack to move stably, thereby driving the gear to drive the scraper to run.

[0011] To drive the scraper to move synchronously along the arc of the fan-shaped transparent observation plate: As a further improvement to the above technical solution: the gear shaft passes through the bottom surface of the movable cavity and is rotatably connected to it, and the gear shaft is coaxial with the center of the fan-shaped mounting window.

[0012] The beneficial effects of this improvement are: limiting the coaxiality of the gear shaft and the center of the fan-shaped mounting window, allowing the swing rod connecting the gear to rotate around the center, driving the scraper to move synchronously along the arc of the fan-shaped transparent observation plate, ensuring that the scraper can cover the entire surface of the observation plate.

[0013] To achieve the mixing of diamond powder with other materials: As a further improvement to the above technical solution: a mesh screen is fixed inside the mounting shell, and two sets of guide plates are symmetrically arranged on both sides of the mesh screen corresponding to the inner walls of the two sides of the mounting shell. A guide seat is fixed between the two sets of guide plates. A support rod fixed at the bottom inner wall of the guide seat is connected to the protective shell. A motor is installed inside the protective shell. The output shaft of the motor passes through and is rotatably connected to the protective shell. The output shaft of the motor is connected to a rotating rod. A stirring rod at the end of the rotating rod is attached to the inner wall of the stirring cylinder. A connecting seat is sleeved on the outside of the stirring cylinder. The connecting seat is fixed to the bottom surface of the mounting shell. A discharge valve is installed at the bottom of the stirring cylinder.

[0014] The beneficial effects of this improvement are as follows: the diamond powder is filtered through a screen to block impurities, and the filtered diamond powder is guided precisely into the mixing drum by the guide plate and guide seat. The mixing of diamond powder with other materials is achieved by the motor-driven rotating rod and stirring rod inside the protective shell.

[0015] To shake off the attached diamond powder: As a further improvement to the above technical solution: an arc-shaped guide rod is fixedly provided in the movable groove to guide the sliding of the movable plate. A spring is sleeved on the outside of the guide rod, and the two ends of the spring are respectively connected to the inner wall of one side of the movable groove and one side of the movable plate.

[0016] The beneficial effects of this improvement are: the spring pushes the movable plate back to its original position after the scraper presses it with elastic force, and at the same time, the movable plate vibrates slightly during the resetting process, shaking off the attached diamond powder.

[0017] To allow operators to unpack diamond powder and adjust materials without opening the equipment: As a further improvement to the above technical solution: two sets of through holes are symmetrically opened on one side of the mounting shell, and dustproof gloves for workers to operate are installed in the through holes.

[0018] The beneficial effects of this improvement are: dustproof gloves are installed inside the through hole on one side of the mounting shell, allowing operators to unpack diamond powder and adjust materials without opening the device.

[0019] In order to unify the control of this device: As a further improvement to the above technical solution: a controller is provided on one side of the mounting shell, and the controller is equipped with a PLC microcontroller, a relay module, and a control switch. The controller is electrically connected to a micro motor, a motor, and a discharge valve.

[0020] The beneficial effect of this improvement is that it enables unified control of the device.

[0021] In summary, the beneficial effects of this case are as follows: The operator can start the scraping assembly through the controller. The micro motor in the mounting cavity drives the lead screw to rotate, and the slide bar drives the rack to move under the guidance of the limit rod, which in turn drives the gear to rotate. Since the gear shaft is coaxial with the center of the fan-shaped mounting window, the swing rod can drive the scraper to slide along the arc of the observation plate, directly scraping the surface dust layer into the mounting shell and restoring the clarity of observation in real time. At the same time, when the scraper swings, it squeezes the movable plate in the movable groove. The movable plate slides along the arc guide rod and compresses the spring. When the scraper returns to its original position, the spring pushes the movable plate back and generates a slight vibration, shaking off the dust remaining on the surface of the movable plate and in the movable groove.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0025] like Figure 1-7As shown, a dust-proof feeding and mixing device for diamond cutting powder includes a mounting shell 1. The top surface of the mounting shell 1 is threadedly connected to the bottom surface of the mounting base 2, and a sealing gasket is provided at the connection between the mounting shell 1 and the mounting base 2. A top plate 13 is fixedly provided on the top surface of the mounting base 2. An installation window 1302 is provided through the center of the top plate 13. Partition plates are fixed at both ends of the installation window 1302, and a movable groove 1301 is left between the partition plates and the inner wall of the end of the installation window 1302. A powder-vibrating assembly 4 is provided in the movable groove 1301. The powder-vibrating assembly 4 includes a movable component that is slidably disposed in the movable groove 1301. The movable plate 401 abuts against the scraper assembly 12 disposed in the mounting base 2. The scraper assembly 12 includes a lead screw 1205, which is threaded through and connected to a slide bar 1202. A rack 1203 is fixedly provided on one side of the slide bar 1202, and the rack 1203 is meshed with a gear 1204. The shaft of the gear 1204 is connected to a swing rod 1206, and a scraper 1201 is provided on the top surface of the swing rod 1206. The scraper 1201 fits against the transparent observation plate disposed in the mounting window 1302, and one end of the scraper 1201 abuts against one side of the movable plate 401.

[0026] The installation window 1302 is fan-shaped, and the center of the mounting base 2 is provided with a fan-shaped through hole corresponding to the installation window 1302. One end of the partition plate faces the center of the fan-shaped installation window 1302. The fan-shaped window expands the viewing angle, and the operator can grasp the internal situation of the device from multiple directions.

[0027] The mounting base 2 has a movable cavity 202 and a mounting cavity 201 arranged sequentially from top to bottom on one side. The movable cavity 202 has a movable window through which the swing rod 1206 swings through the inner wall of the side facing the central through hole of the mounting base 2. The gear 1204 is rotatably mounted on the inner bottom surface of the mounting cavity 201 via a bearing. A micro motor is embedded in the inner wall of one side of the mounting cavity 201, and the output shaft of the micro motor is connected to one end of the lead screw 1205. A limit rod is provided on one side of the lead screw 1205, and the two ends of the limit rod are connected to the inner walls of both sides of the mounting cavity 201. The slide bar 1202 is slidably sleeved on the outside of the limit rod. The micro motor drives the lead screw to rotate, and the limit rod restricts the movement direction of the slide bar 1202, ensuring that the slide bar drives the rack 1203 to move stably, thereby driving the gear 1204 to drive the scraper to run.

[0028] The shaft of the gear 1204 passes through the bottom surface of the movable cavity 202 and is rotatably connected to it. The shaft of the gear 1204 is coaxial with the center of the fan-shaped mounting window 1302. By limiting the coaxiality between the shaft of the gear 1204 and the center of the fan-shaped mounting window 1302, the swing rod 1206 connected to the gear rotates around the center, driving the scraper 1201 to move synchronously along the arc of the fan-shaped transparent observation plate, ensuring that the scraper can cover the entire surface of the observation plate.

[0029] The interior of the mounting shell 1 is fixedly equipped with a mesh screen 5, and two sets of guide plates 6 are symmetrically arranged on the lower two sides of the mesh screen 5 corresponding to the inner walls of the two sides of the mounting shell 1. A guide seat 7 is fixed between the two sets of guide plates 6. A support rod fixed at the bottom inner wall of the guide seat 7 is connected to a protective shell 8. A motor is installed inside the protective shell 8. The output shaft of the motor passes through and is rotatably connected to the protective shell 8. The output shaft of the motor is connected to a rotating rod 9. A stirring rod at the end of the rotating rod 9 is attached to the inner wall of the mixing cylinder 10. A connecting seat 101 is sleeved on the outside of the mixing cylinder 10. The connecting seat 101 is fixed to the bottom surface of the mounting shell 1. A discharge valve 11 is installed at the bottom of the mixing cylinder 10. The diamond powder is filtered through the mesh screen 5 to block impurities. The filtered diamond powder is guided precisely into the mixing cylinder 10 by the guide plates 6 and the guide seat 7. The rotating rod 9 and the stirring rod are driven by the motor inside the protective shell 8 to achieve mixing of diamond powder with other materials.

[0030] An arc-shaped guide rod 402 is fixedly installed inside the movable groove 1301 to guide the movable plate 401 to slide. A spring is sleeved on the outside of the guide rod 402, and the two ends of the spring are respectively connected to the inner wall of one side of the movable groove 1301 and one side of the movable plate 401. The spring pushes the movable plate to reset after the scraper 1201 squeezes it with elastic force. At the same time, the movable plate vibrates slightly during the reset process, shaking off the attached diamond powder.

[0031] Two sets of through holes are symmetrically opened on one side of the mounting shell 1, and dust gloves for workers to operate are installed in the through holes; dust gloves are installed in the through holes on one side of the mounting shell 1 so that operators can unpack diamond powder and adjust materials without opening the device.

[0032] A controller is provided on one side of the mounting housing 1, and the controller is equipped with a PLC microcontroller, a relay module, and a control switch. The controller is electrically connected to a micro motor, a motor, and a discharge valve 11.

[0033] The working principle and usage process of this utility model are as follows: The operator places the packaging bag containing diamond cutting powder on the strainer 5, then connects the mounting shell 1 and the mounting base 2 by threads. The operator puts both hands into the dust gloves on one side of the mounting shell 1 and opens the sealed bag in a closed environment. During the opening process, the diamond cutting powder falls into the mounting shell 1 through the fan-shaped through hole of the mounting base 2, first contacting the horizontally set strainer 5. The strainer 5 blocks any impurities that may be mixed in, and the pure diamond cutting powder falls through the strainer 5 and is guided by the symmetrical guide plates 6 on both sides to the guide seat 7 in the middle, and finally flows into the lower part of the casing through the guide seat 7. In the square mixing drum 10, some diamond cutting powder may fall or adhere to the transparent observation plate due to airflow, causing blurred vision. When dust on the observation plate affects vision, the operator activates the scraping assembly 12 via the controller. The micro motor in the mounting cavity 201 drives the lead screw 1205 to rotate. The slide bar 1202, which is threaded to the lead screw 1205, moves horizontally under the guidance of the limit rod. The rack 1203 on one side of the slide bar 1202 moves synchronously and meshes, driving the gear 1204 to rotate. Since the shaft of the gear 1204 is aligned with the center of the fan-shaped mounting window 1302... When the coaxial gear 1204 rotates, it drives the connected swing rod 1206 to swing around the center axis through the movable window of the movable cavity 202 below the transparent observation plate. The scraper 1201 on the top surface of the swing rod 1206 slides against the bottom surface of the observation plate, scraping off the attached diamond powder. At the same time, one end of the scraper 1201 presses against the movable plate 401 in the movable groove 1301 during the swing. The movable plate 401 slides along the arc-shaped guide rod 402 towards the inside of the movable groove 1301 and compresses the spring. When the scraper 1201 swings in the opposite direction, the spring returns to its original position and pushes the movable plate 401 back. During the back movement... Slight vibrations are generated, causing the diamond powder remaining on the surface of the movable plate 401 and in the movable groove 1301 to fall into the mounting shell 1. Through the synergy of scraping and shaking, the transparent observation plate remains clear, allowing the operator to observe the amount of material in the mixing drum 10 in real time. The operator starts the stirring motor in the protective shell 8 through the controller. The motor output shaft drives the rotating rod 9 to rotate. The stirring rod at the end of the rotating rod 9 rotates inside the mixing drum 10. The stirring rod, which is in contact with the inner wall of the mixing drum 10, fully mixes the diamond cutting powder with the pre-added liquid. The mixed material is discharged from the discharge valve 11 into the collection container to complete the operation.
