[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] like Figures 1 to 6 As shown, the utility model provides a rotary drum grinder, comprising: a grinding part and a driving part, the grinding part comprises a grinding cylinder 1 and a filter element 2 and a cylinder shell 3 which are sleeved on the outside of the grinding cylinder 1, one end of the grinding cylinder 1, the filter element 2 and the cylinder shell 3 are provided with inlet and outlet ports, and are covered with an end cover 31 for sealing the inlet and outlet ports; a feeding port 11 is opened on one side of the grinding cylinder 1, and a sealing plate 12 for sealing the feeding port 11 is movably inserted at a position corresponding to the feeding port 11 on one side of the end cover 31; a pipe port 36 connected to the inside of the cylinder shell is provided on the cylinder shell 3; the driving part is connected to one end of the grinding part away from the inlet and outlet ports, so as to drive the grinding part to rotate.

[0028] In the present device, the interior of the grinding cylinder 1 is used to accommodate glass workpieces, and the workpieces can be fed into the grinding cylinder 1 through the inlet and outlet ports. The driving part is connected to the grinding part and can drive the grinding part to rotate, thereby driving the grinding cylinder 1 to rotate, so as to achieve grinding and polishing of the workpiece surface through long-term continuous rotation; by sequentially sleeved with a filter element 2 and a cylinder shell 3 on the outside of the grinding cylinder 1, and opening a feed port 11 on one side of the grinding cylinder 1, and providing a sealing plate 12 for sealing the feed port 11, during the grinding process, the sealing plate 12 is provided on the feed port 11 to seal the feed port 11 so that the grinding cylinder 1 can rotate to grind the workpiece. After polishing, the sealing plate 12 is adjusted to the bottom of the grinding cylinder 1 by rotating the grinding cylinder 1. At this time, The sealing plate 12 can be pulled out on one side of the end cover 31 to open the feed port 11, so that the workpiece can fall into the space between the inner wall of the filter element 2 and the outer wall of the grinding cylinder 1 through the feed port 11 under the action of gravity. The cylinder shell 3 is provided with a pipe mouth 36 connected to the interior thereof, and cleaning water can be poured into the cylinder shell 3 through the pipe mouth 36. At the same time, when the driving unit drives the grinding unit to rotate, the workpiece can roll between the inner wall of the filter element 2 and the outer wall of the grinding cylinder 1 and be fully contacted with water for cleaning, and the workpiece can be separated from impurities by the filter element 2, so as to clean the dust and other impurities on the workpiece without opening the grinding piece. When draining water, the pipe mouth 36 can be adjusted to the bottom, and the pipe mouth 36 can be used as a drainage pipe to discharge the water inside the cylinder shell 3.

[0029] It should be noted that, in operation, the grinding part is usually tilted so that the workpiece can slide or roll during the rotation process. There is a polishing pad inside the grinding cylinder 1 and inside the sealing plate 12. When the workpiece contacts the polishing pad, friction occurs, which helps to remove paint contamination, oxide layer and shallow marks on the surface of the workpiece. During the rough polishing process, a large amount of steel balls, lime and abrasives can be loaded in the drum. These materials roll and collide randomly when the drum rotates, thereby removing the protrusions on the surface and reducing the roughness. During fine polishing, steel balls and fur fragments can be loaded into the drum, and a very smooth surface can be obtained by continuous rotation for a long time.

[0030] In order to be able to adjust the inclination angle of the grinding part, such as Figure 1As shown, in some embodiments, the rotary drum grinder further includes a support frame 6, a rotating shaft 7 and an adjusting member 8, wherein the rotating shaft 7 is rotatably arranged on the support frame 6, and both ends of the rotating shaft 7 are rotatably connected to the support frame 6, the barrel shell 3 of the grinding part is fixedly connected to the rotating shaft 7 through a mounting box 71, the filter element 2 and the grinding barrel 1 are fixedly connected to the barrel shell 3, and the adjusting member 8 is arranged on one side of the support frame 6, and its driving end is connected to one end of the rotating shaft 7, so as to adjust the inclination angle of the grinding part by driving the rotating shaft 7 to rotate. Specifically, the adjusting member 8 includes a second motor, which is mounted on one side of the support frame 6 through a mounting plate, and the driving shaft of the second motor is fixedly connected to one end of the rotating shaft 7.

[0031] It is understandable that in order to facilitate the precise adjustment of the inclination angle by the motor, the second motor is connected to the controller via a sensor, and the rotation angle of the drive shaft of the second motor can be controlled by the controller. During implementation, the second motor drives the rotating shaft 7 to rotate, thereby driving the grinding part connected to the rotating shaft 7 to rotate along the rotating shaft 7 to adjust the inclination angle of the grinding part.

[0032] In other possible embodiments, the adjusting member 8 for driving the rotating shaft 7 to rotate may also be other structures such as a manual wheel connected to the rotating shaft 7. When it is a manual wheel, the rotating shaft 7 can be rotated by the manual wheel to adjust the inclination angle of the grinding part. When the manual wheel is connected to the support frame 6 by bolts, the rotation limit is achieved to fix the grinding part. It should be noted that the torque can also be transmitted between the manual wheel and the rotating shaft 7 by setting a gear set or a pulley set.

[0033] In order to realize the driving of the grinding part to rotate, Figure 2 As shown, in some embodiments, the driving part includes a first motor 4 and a transmission member 5, and the driving shaft of the first motor 4 is connected to the cylinder shell 3 through the transmission member 5, so as to transmit torque through the transmission member 5 to drive the cylinder shell 3 to rotate. Specifically, the transmission member 5 includes a first pulley 51, a second pulley 52 and a belt 53, one end of the cylinder shell 3 is coaxially fixedly connected to a connecting shaft, one end of the connecting shaft passes through the installation box 71 and is rotatably connected to the installation box 71, the first pulley 51 is coaxially connected to the connecting shaft at one end of the cylinder shell 3, a chassis 72 is provided at the bottom of the installation box 71, the first motor 4 is installed inside the chassis 72, the second pulley 52 is coaxially connected to the driving shaft of the first motor 4, and the belt 53 is sleeved between the first pulley 51 and the second pulley 52. During implementation, the second pulley 52 is driven to rotate by the first motor 4, thereby driving the first pulley 51, the connecting shaft and the cylinder shell 3 to rotate through the belt 53. Since the grinding cylinder 1 and the filter screen cylinder 21 are fixedly connected to the cylinder shell 3, the rotation of the cylinder shell 3 can drive the grinding cylinder 1 and the filter screen cylinder 21 to rotate synchronously.

[0034] In other possible implementations, the transmission member 5 may also be other components capable of transmitting torque, such as a gear set.

[0035] Specifically, Figure 2 , Figure 4 , Figure 5 As shown, in some embodiments, the filter element 2 includes a filter screen cylinder 21, and the filter screen cylinder 21 is arranged at intervals on the outside of the grinding cylinder 1, and the filter screen cylinder 21 and one end of the grinding cylinder 1 are fixedly connected to the cylinder shell 3, and the grinding cylinder 1 is a polygonal cylindrical structure, one side of which is provided with the feed port 11 and a corresponding sealing plate 12, wherein a gap is reserved between the filter screen cylinder 21 and the grinding cylinder 1 and the cylinder shell 3. In order to facilitate the introduction of the working principle of the grinding part, the interior of the grinding cylinder 1 is defined as a grinding chamber 101, the interlayer between the grinding cylinder 1 and the filter screen cylinder 21 is defined as a cleaning chamber 102, and the interlayer between the filter screen cylinder 21 and the cylinder shell 3 is defined as an impurity chamber 103.

[0036] During operation, the workpiece is first polished and ground in the polishing chamber 101. When the polishing is completed, the sealing plate 12 is pulled out to open the feed port 11, so that the workpiece can pass through the feed port 11 into the cleaning chamber 102, and then the polishing part is driven to rotate by the driving part, so that the workpiece comes into contact with water in the cleaning chamber 102 for cleaning. At the same time, the workpiece is kept in the cleaning chamber 102 through filtering by the filter cylinder 21, and impurities will fall into the impurity chamber 103, thereby realizing the separation of the workpiece and impurities.

[0037] like Figure 4 , Figure 5 As shown, in some embodiments, in order to improve the stability of the sealing plate 12 when it is at the feeding port 11, the middle parts of the opposite side walls of the feeding port 11 are both recessed inward to form grooves, and the two sides of the sealing plate 12 extend into the two grooves respectively and are slidably connected with the grooves; an insert plate 34 is provided at one end of the sealing plate 12, and the insert plate 34 is inserted and connected to the insertion hole opened on the end cover 31, the cross-sectional area of ​​the insert plate 34 is larger than the cross-sectional area of ​​the sealing plate 12, and a handle 35 is connected to one side of the insert plate 34; so that when implementing, the handle 35 can be used to take out or insert the insert plate 34 and the sealing plate 12.

[0038] In order to prevent cleaning water from entering the grinding cylinder 1, in some embodiments, sealing gaskets are provided on the side walls of the groove. When the sealing plate 12 slides into the feed port 11, the sealing gaskets are attached to the sealing plate 12. The inner side of the end cover 31 and the corresponding positions of the cylinder shell 3, the filter screen cylinder 21 and the grinding cylinder 1 are provided with sealing strips to play a waterproof role.

[0039] like Figure 6As shown, in some embodiments, in order to achieve fixed limitation of the end cover 31, one side of the end cover 31 is hingedly connected to the cylinder shell 3, and a screw rod 32 is provided on the end of the cylinder shell 3 away from the hinged end of the end cover 31, and a limiting rod 33 perpendicular to the screw rod 32 is threadedly connected, and the limiting rod 33 is rotated to a vertical state so that one end of it abuts against the outer side of the end cover 31, so that the end cover 31 can be fixed, and the limiting rod 33 is rotated to a horizontal setting so that the limiting rod 33 and the end cover 31 are staggered, and the end cover 31 can be opened at this time, and the tightening force of the limiting rod 33 against the outer side of the end cover 31 can be adjusted by setting the screw rod 32, so as to ensure the stability of the end cover 31.

[0040] In other possible implementations, the end cover 31 may also be threadedly connected or fixed to the cylinder shell 3 .

[0041] Working principle: When the workpiece needs to be polished, the end cover 31 is opened, the workpiece is placed inside the grinding cylinder 1, and the first motor 4 is turned on. The first motor 4 drives the second pulley 52 to rotate, and drives the cylinder shell 3, the filter cylinder 21 and the grinding cylinder 1 to rotate through the belt 53 and the first pulley 51 to realize the polishing of the workpiece. After polishing, the sealing plate 12 is adjusted to the bottom of the grinding cylinder 1 according to the position of the insert plate 34, and then the handle 35 is used to pull out the insert plate 34 and the sealing plate 12, and the material port 11 is opened to allow all the workpieces to fall into the cleaning chamber 102. Finally, the sealing plate 12 is inserted back into its original position, and clean water is injected into the cylinder shell 3 through the pipe mouth 36, and then the pipe mouth 36 is closed. At this time, the first motor 4 is used to drive the cylinder shell 3, the filter screen cylinder 21 and the grinding cylinder 1 to rotate, so that the workpiece rolls in the filter chamber to achieve cleaning and filtering of the workpiece. After cleaning, the pipe mouth 36 is adjusted to the bottom to release impurities and water, and then the end cover 31 is opened, and the inlet and outlet of the cylinder shell 3 is adjusted to tilt downward by the second motor, so that the workpiece in the cleaning chamber 102 can be automatically discharged from the inlet and outlet.

[0042] The utility model has a grinding part and a driving part, and during the grinding process, the sealing plate 12 is arranged on the material port 11 to seal the material port 11, and the grinding cylinder 1 can rotate normally to grind the workpiece. After polishing, the sealing plate 12 is adjusted to the bottom of the grinding cylinder 1 by rotating the grinding cylinder 1. At this time, the sealing plate 12 is pulled out on one side of the end cover 31 to open the material port 11, so that the workpiece can pass through the material port 11 and fall between the inner wall of the filter element 2 and the outer wall of the grinding cylinder 1. The cylinder shell 3 is provided with a The nozzle 36 can be used to pour cleaning water into the barrel shell 3. At the same time, the grinding part is driven to rotate by the driving part, so that the workpiece can roll between the inner wall of the filter element 2 and the outer wall of the grinding barrel 1 and fully contact with water for cleaning. The workpiece is separated from impurities by the filter element 2 arranged between the grinding barrel 1 and the barrel shell 3, so that dust and other impurities on the workpiece can be cleaned without opening the grinding piece, avoiding the situation where dust is scattered during unloading and polluting the air, thereby ensuring a good working environment.
