Abstract
Description
Technical Field
[0001] This application relates to the field of sandblasting production equipment technology, and in particular to a feeding device for a sandblasting machine. Background Technology
[0002] A sandblasting machine is a mechanical device that uses compressed air to drive abrasive particles at high speed to be sprayed onto the surface of a workpiece for cleaning, grinding, or surface treatment. Its core working principle is to use compressed air to create negative pressure or pressure inside a pressure tank to accelerate the abrasive particles onto the workpiece surface, thereby achieving functions such as cleaning, rust removal, and increasing roughness.
[0003] Chinese Patent No. CN216657606U discloses a pneumatic rotary table intermittent automated sandblasting machine, which relates to the field of sandblasting machine technology. This utility model fixes the workpiece on a small rotary table mechanism. During operation, the large rotary table mechanism intermittently drives the small rotary table mechanism to rotate into the sandblasting chamber. The cyclone separator provides the sandblasting nozzle with a useful sand source that has been screened by primary sand and dust and is recycled. The compressed air filter provides the sandblasting nozzle with air jet power, so that the sandblasting nozzle performs sandblasting operation on the workpiece. At the same time, the air nozzle blows the sand particles on the large rotary table mechanism to the sand material circulation mechanism.
[0004] When using the above technology, sandblasting of small workpieces is required. Because the sandblasting process for small workpieces is short, frequent loading and unloading of materials is necessary. Small workpieces are usually produced in large quantities, which greatly increases the workload of the workers. Workers are also more likely to make mistakes when working for long periods of time, which is a drawback. Utility Model Content
[0005] To address the problems caused by sandblasting large batches of small workpieces, this application provides a feeding device for a sandblasting machine.
[0006] The feeding device for a sandblasting machine provided in this application adopts the following technical solution:
[0007] A feeding device for a sandblasting machine includes a hollow housing with one open side. An observation door is slidably mounted on the housing. A partition plate is installed inside the housing, dividing the interior into a feeding chamber and a sandblasting chamber. A loading plate is installed in the feeding chamber, and a workpiece placement tray is placed on the loading plate. A sandblasting nozzle is installed in the sandblasting chamber. A shaft is rotatably mounted at the partition plate. A rotating component driving the shaft is mounted on the housing. A central partition plate is mounted on the shaft plate, and the partition plate has openings... The machine housing includes a clearance slot for the rotation of the partition plate, a bridge plate symmetrically arranged on the shaft disk about the partition plate, a workpiece holder rotatably mounted on the bridge plate, a feeding assembly, a sand supply assembly, and a rotating assembly. When the partition plate is parallel to the dividing plate, the feeding assembly replaces the workpiece on the feeding tray with the workpiece on the workpiece holder in the feeding chamber. The sand supply assembly causes the sandblasting nozzle to sandblast the workpiece on the workpiece holder in the sandblasting chamber. The rotating assembly causes the workpiece holder in the sandblasting chamber to rotate.
[0008] By adopting the above technical solution, the operator first places the workpiece-containing tray on the loading plate, then closes the observation door and starts the control system. The rotating component drives the shaft to rotate 180 degrees, causing the workpiece seat located in the sandblasting chamber to move to the loading chamber. Then, the loading assembly replaces the workpiece on the tray with the workpiece on the seat in the loading chamber. The sandblasting nozzle then sandblasts the workpiece on the seat that has moved from the loading chamber to the sandblasting chamber. At the same time, the rotating component drives the seat in the sandblasting chamber to rotate, so that the workpiece is uniformly sandblasted circumferentially. Then, the rotating component drives the shaft to rotate 180 degrees again, and the operation is repeated until the workpiece on the tray has been completely replaced once. This reduces the workload of the operator and improves the processing efficiency of the workpiece.
[0009] Optionally, the rotating component includes a rotating motor disposed on the housing and electrically connected to the control system, a transmission shaft being coaxially disposed on the output shaft of the rotating motor, and the shaft disc being coaxially disposed on the transmission shaft.
[0010] By adopting the above technical solution, the control system starts the rotating motor, and the output shaft of the rotating motor drives the shaft disc to rotate through the transmission shaft, thereby realizing the process of alternating circulation between the placement seat in the feeding chamber and the placement seat in the sandblasting chamber.
[0011] Optionally, the feeding assembly includes a first linear module disposed on the housing and located in the feeding chamber. A second linear module is disposed on the slide of the first linear module. The slide of the first linear module slides along the X-axis in a three-dimensional coordinate system. A vertical cylinder is disposed on the slide of the second linear module. The slide of the second linear module slides along the Y-axis in a three-dimensional coordinate system. The piston rod of the vertical cylinder extends along the Z-axis in a three-dimensional coordinate system. A gripper cylinder is disposed on the piston rod of the vertical cylinder. The first linear module, the second linear module, the vertical cylinder, and the gripper cylinder are all electrically connected to the control system.
[0012] By adopting the above technical solution, the control system starts the first linear module, the second linear module, the vertical cylinder and the gripper cylinder in sequence, so that the gripper cylinder can replace the processed workpiece on the workpiece holder with the unprocessed workpiece on the material tray.
[0013] Optionally, the sand supply assembly includes a cyclone separator and an air pump mounted on the housing. Both the cyclone separator and the air pump are electrically connected to the control system. An air supply hose is connected between the air pump and the sandblasting nozzle. A sand supply pipe is connected between the outlet of the cyclone separator and the sandblasting nozzle.
[0014] By adopting the above technical solution, the control system starts the cyclone separator and the air pump. The air pump supplies high-pressure airflow to the sandblasting nozzle through the air supply hose. The cyclone separator delivers the sand to the sandblasting nozzle through the sand supply pipe. At the sandblasting nozzle, the sand is impacted on the workpiece by the high-speed airflow, thereby sandblasting the surface of the workpiece.
[0015] Optionally, the rotating assembly includes a driven wheel coaxially mounted on the mounting base, and two driving wheels rotatably mounted inside the housing. A belt is fitted onto the two driving wheels, and the driven wheel abuts against the belt. When the partition plate is parallel to the dividing plate, the driven wheel is not on the same straight line as the two driving wheels. A rotary motor electrically connected to the control system is mounted on the housing, and one of the driving wheels is coaxially mounted on the output shaft of the rotary motor. A tensioning element for adjusting the belt tension is mounted on the housing.
[0016] By adopting the above technical solution, the control system starts the rotary motor, and the output shaft of the rotary motor drives one of the active rollers to rotate. The active roller drives the belt to rotate through friction, and the rotating belt drives the driven roller to rotate through friction. The driven roller drives the workpiece to rotate through the workpiece holder. During the rotation of the shaft disc, the driven roller in the sandblasting chamber will gradually move away from the belt, while the driven roller in the feeding chamber will gradually move closer to the belt until the middle partition is parallel to the partition plate. During this process, the tensioning element continuously changes the tension of the belt, so that the belts on the two active rollers will not accidentally fall off.
[0017] Optionally, the tensioning element includes a support plate disposed on the housing, a slide rod disposed on the support plate, a slider slidably sleeved on the slide rod, a tensioning wheel rotatably disposed on the slider, the tensioning wheel and the two driving wheels not being on the same straight line, a baffle disposed on the side of the support plate near the shaft disk, and a tensioning spring supporting the baffle and the slider.
[0018] By adopting the above technical solution, as the driven roller in the sandblasting chamber gradually moves away from and separates from the belt, the tension spring recovers its deformation, and the distance between the tension roller and the driving roller increases; as the driven roller in the feeding chamber gradually approaches and abuts the belt, the tension spring is compressed again, and the distance between the tension roller and the driving roller decreases again, thereby reducing the possibility of the belt accidentally falling off.
[0019] Optionally, a material collection hopper is provided inside the housing and below the sandblasting nozzle, and a sand return pipe is connected between the material collection hopper and the feed inlet of the cyclone separator.
[0020] By adopting the above technical solution, the sand sprayed from the sandblasting nozzle is collected by the collecting hopper and then flows back to the cyclone separator through the sand return pipe with the airflow, so that the sandblasting can be recycled.
[0021] Optionally, the housing is provided with a dust collector electrically connected to the control system, and the air inlet of the dust collector is connected to the top of the cyclone separator by a dust collection pipe.
[0022] By adopting the above technical solutions, the impact of dust on the working environment of employees has been reduced.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The operator first places the workpiece-containing tray onto the loading plate, then closes the observation door and starts the control system. The rotating drive shaft rotates 180 degrees, causing the workpiece seat in the sandblasting chamber to move to the loading chamber. Then, the loading assembly replaces the workpiece on the tray with the workpiece on the workpiece seat in the loading chamber. The sandblasting nozzle then sandblasts the workpiece on the workpiece seat that has moved from the loading chamber to the sandblasting chamber. At the same time, the rotating assembly drives the workpiece seat in the sandblasting chamber to rotate, so that the workpiece is sandblasted evenly in the circumference. Then, the rotating drive shaft rotates 180 degrees again, and the operation is repeated until the workpiece on the tray has been completely replaced once. This reduces the workload of the operator and improves the processing efficiency of the workpiece.
[0025] 2. The control system starts the rotary motor. The output shaft of the rotary motor drives one of the driving wheels to rotate. The driving wheel drives the belt to rotate through friction. The rotating belt drives the driven wheel to rotate through friction. The driven wheel drives the workpiece to rotate through the workpiece holder. During the rotation of the shaft disc, the driven wheel in the sandblasting chamber will gradually move away from the belt, while the driven wheel in the feeding chamber will gradually move closer to the belt until the middle partition is parallel to the partition plate. During this process, the tensioner continuously changes the tension of the belt, so that the belt on the two driving wheels will not accidentally fall off.
[0026] 3. As the driven roller in the sandblasting chamber gradually moves away from and separates from the belt, the tension spring recovers its deformation, and the distance between the tension roller and the driving roller increases. As the driven roller in the feeding chamber gradually approaches and abuts the belt, the tension spring is compressed again, and the distance between the tension roller and the driving roller decreases again. This reduces the possibility of the belt accidentally falling off. Attached Figure Description

[0038] Reference Figure 2 , Figure 3 and Figure 4 When the partition plate 12 is parallel to the dividing plate 4, the feeding assembly 16 is used to replace the workpiece 1 on the material tray 8 with the workpiece 1 on the placement seat 15 in the feeding chamber 5. The sand supply assembly 17 is used to make the sandblasting nozzle 9 sandblast the workpiece 1 on the placement seat 15 in the sandblasting chamber 6. The rotating assembly 18 is used to make the placement seat 15 in the sandblasting chamber 6 rotate.
[0039] Reference Figure 2 The feeding assembly 16 includes a first linear module 161 bolted to the housing 2 and located in the feeding chamber 5. A second linear module 162 is bolted to the slide of the first linear module 161. Both the first linear module 161 and the second linear module 162 adopt the enclosed dustproof electric slide module in the prior art. The slide of the first linear module 161 slides along the X-axis direction in the three-dimensional coordinate system. A vertical cylinder 163 is bolted to the slide of the second linear module 162.
[0040] Reference Figure 2 The slide of the second linear module 162 slides along the Y-axis in the three-dimensional coordinate system, and the piston rod of the vertical cylinder 163 extends along the Z-axis in the three-dimensional coordinate system. A gripper cylinder 164 is bolted to the piston rod of the vertical cylinder 163. The first linear module 161, the second linear module 162, the vertical cylinder 163 and the gripper cylinder 164 are all electrically connected to the control system.
[0041] The staff first places the placement tray 8 containing workpiece 1 on the loading plate 7, then closes the observation door 3 and starts the control system. The control system sequentially starts the first linear module 161, the second linear module 162, the vertical cylinder 163, and the gripper cylinder 164. The gripper cylinder 164 grips the workpiece 1 on the placement tray 8. At the same time, under the combined action of the first linear module 161, the second linear module 162, and the vertical cylinder 163, the workpiece 1 is picked up.
[0042] The gripper cylinder 164 places the gripped workpiece 1 onto the placement seat 15 in the loading chamber 5. Then, the control system starts the rotating motor 111. The output shaft of the rotating motor 111 drives the transmission shaft 112 to rotate 180 degrees. The rotating transmission shaft 112 drives the shaft disc 10 to rotate synchronously. The rotating shaft disc 10 switches the placement seat 15 located in the sandblasting chamber 6 with the placement seat 15 located in the loading chamber 5.
[0043] Reference Figure 2 and Figure 4 The sand supply assembly 17 includes a cyclone separator 171 and an air pump 172 bolted to the housing 2. Both the cyclone separator 171 and the air pump 172 are electrically connected to the control system. An air supply hose 173 is connected between the air pump 172 and the sand blasting nozzle 9. A sand supply pipe 174 is connected between the outlet of the cyclone separator 171 and the sand blasting nozzle 9.
[0044] Reference Figure 2 and Figure 4 Inside the housing 2 and below the sandblasting nozzle 9, a collection hopper 19 is bolted. A metal filter screen (not shown in the figure) is bolted to the collection hopper 19. A return sand pipe 20 is connected between the bottom of the collection hopper 19 and the feed inlet of the cyclone separator 171. A dust collector 21 electrically connected to the control system is bolted to the housing 2. A dust collection pipe 22 is connected between the air inlet of the dust collector 21 and the top of the cyclone separator 171.
[0045] The control system starts the cyclone separator 171 and the air pump 172. The cyclone separator 171 delivers sand to the sandblasting nozzle 9 through the sand supply pipe 174. At the same time, the air pump 172 delivers high-pressure airflow to the sandblasting nozzle 9 through the air supply hose 173, so that the sandblasting continuously impacts the surface of the workpiece 1 with the high-pressure airflow, thereby performing sandblasting treatment on the surface of the workpiece 1.
[0046] Reference Figure 2 and Figure 3 The rotating assembly 18 includes a driven wheel 181 coaxially bolted to the bottom of the mounting base 15. Two driving wheels 182 are rotatably connected inside the housing 2. Belts 183 are sleeved on the two driving wheels 182. The driven wheel 181 is used to abut against the belts 183. When the middle partition 12 is parallel to the partition plate 4, the driven wheel 181 and the two driving wheels 182 are not on the same straight line. A rotary motor 184 electrically connected to the control system is bolted to the housing 2. One of the driving wheels 182 is coaxially bolted to the output shaft of the rotary motor 184.
[0047] Reference Figure 2 and Figure 3The housing 2 is provided with a tensioning member 185 for adjusting the tension of the belt 183. The tensioning member 185 includes a support plate 1851 bolted to the inner wall of the housing 2. A slide rod 1852 is welded on the support plate 1851. A slider 1853 is slidably sleeved on the slide rod 1852. A tension wheel 1854 is rotatably connected to the slider 1853. The tension wheel 1854 is not on the same straight line as the two drive wheels 182. A baffle 1855 is welded on the side of the support plate 1851 near the shaft disc 10. A tension spring 1856 supports the baffle 1855 and the slider 1853.
[0048] The control system starts the rotary motor 184. The output shaft of the rotary motor 184 drives one of the driving wheels 182 to rotate. The rotating driving wheel 182 drives the driven wheel 181 located in the sandblasting chamber 6 to rotate via the belt 183. The rotating driven wheel 181 drives the workpiece seat 15 to rotate, thereby causing the workpiece 1 located on the workpiece seat 15 to be sandblasted in the circumferential direction.
[0049] After the workpiece 1 on the placement seat 15 in the sandblasting chamber 6 is sandblasted, the control system starts the rotating motor 111. The output shaft of the rotating motor 111 drives the shaft disk 10 to rotate 180 degrees through the transmission shaft rod 112. During this process, as the driven wheel 181 in the sandblasting chamber 6 gradually moves away from and separates from the belt 183, the tension spring 1856 returns to its original deformation.
[0050] The distance between the tensioning pulley 1854 and the driving pulley 182 increases, and the belt 183 remains taut. As the driven pulley 181 in the feeding chamber 5 gradually approaches and abuts against the belt 183, the tensioning spring 1856 is compressed again, and the distance between the tensioning pulley 1854 and the driving pulley 182 decreases again, and the belt 183 remains taut.
[0051] The implementation principle of a feeding device for a sandblasting machine according to an embodiment of this application is as follows: The operator first places the material tray 8 with the workpiece 1 on the material carrier plate 7, then closes the observation door 3 and starts the control system. The control system sequentially starts the first linear module 161, the second linear module 162, the vertical cylinder 163 and the gripper cylinder 164. The gripper cylinder 164 grips the workpiece 1 on the material tray 8. At the same time, under the combined action of the first linear module 161, the second linear module 162 and the vertical cylinder 163.
[0052] The gripper cylinder 164 places the gripped workpiece 1 onto the placement seat 15 in the loading chamber 5. Then, the control system starts the rotating motor 111. The output shaft of the rotating motor 111 drives the transmission shaft 112 to rotate 180 degrees. The rotating transmission shaft 112 drives the shaft disc 10 to rotate synchronously. The rotating shaft disc 10 switches the placement seat 15 located in the sandblasting chamber 6 with the placement seat 15 located in the loading chamber 5.
[0053] The control system starts the cyclone separator 171 and the air pump 172. The cyclone separator 171 delivers sand to the sandblasting nozzle 9 through the sand supply pipe 174. At the same time, the air pump 172 delivers high-pressure airflow to the sandblasting nozzle 9 through the air supply hose 173, so that the sandblasting continuously impacts the surface of the workpiece 1 with the high-pressure airflow, thereby performing sandblasting treatment on the surface of the workpiece 1.
[0054] The control system starts the rotary motor 184. The output shaft of the rotary motor 184 drives one of the driving wheels 182 to rotate. The rotating driving wheel 182 drives the driven wheel 181 located in the sandblasting chamber 6 to rotate via the belt 183. The rotating driven wheel 181 drives the workpiece seat 15 to rotate, thereby causing the workpiece 1 located on the workpiece seat 15 to be sandblasted in the circumferential direction.
[0055] After the workpiece 1 on the placement seat 15 in the sandblasting chamber 6 is sandblasted, the control system starts the rotating motor 111. The output shaft of the rotating motor 111 drives the shaft disk 10 to rotate 180 degrees through the transmission shaft rod 112. During this process, as the driven wheel 181 in the sandblasting chamber 6 gradually moves away from and separates from the belt 183, the tension spring 1856 returns to its original deformation.
[0056] The distance between the tensioning pulley 1854 and the driving pulley 182 increases, and the belt 183 remains taut. As the driven pulley 181 in the feeding chamber 5 gradually approaches and abuts against the belt 183, the tensioning spring 1856 is compressed again, and the distance between the tensioning pulley 1854 and the driving pulley 182 decreases again, and the belt 183 remains taut.
[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
