Description

Technical Field

[0001] The utility model relates to the technical field of coating processing, and more specifically, to a grinding device for producing salt-fog resistant coatings. Background Art

[0002] Salt spray resistant coating, as a special type of coating, has high water resistance and corrosion resistance. It is often used in high-salinity environments such as marine environments and coastal areas. It can slow down the corrosion of salt spray on machinery and increase the service life of machinery. In order to make the particle size of salt spray resistant coating finer and the mixing more uniform, a ball mill is usually used to grind the salt spray resistant coating during its manufacture.

[0003] During the use of existing ball mills, the paint and grinding balls are usually added into the barrel of the ball mill together, and then the opening of the barrel is closed, and then the motor is started to drive the barrel to rotate. At this time, the grinding balls in the barrel will collide and rub against the paint, making the coating more delicate under the influence of the grinding balls. After the paint is ground, the opening of the barrel is opened, and the paint and grinding balls are taken out to complete the grinding of the paint.

[0004] However, when taking out the paint from the ball mill, since the cylinder of the ball mill is mostly cylindrical, the staff needs to use a shovel or other tools to take out the paint and grinding balls from the cylinder. During this period, the staff needs to frequently put the shovel or other tools into the ball mill, which is too cumbersome. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a grinding equipment for the production of salt spray resistant coatings, which solves the problem that when taking out the coating from the ball mill, the staff needs to use a shovel or other tools to take out the coating and grinding balls in the cylinder, which is a cumbersome process.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: A grinding equipment for the production of salt spray resistant coatings, comprising a body and a barrel and a motor connected to each other, the side wall of the barrel is fixedly connected to a discharge box that is mutually conductive with the barrel, the side of the discharge box away from the barrel is fixedly connected to a rotating frame 1, the inner side wall of the rotating frame 1 is provided with a connecting rod arranged in a cross, two ends of the connecting rod are rotatably connected to the rotating frame 1, and the other two ends are rotatably connected to the rotating frame 2, the output end of the motor is fixedly connected to the rotating frame 2, the body is provided with a limiting component for limiting the direction of the rotating frame 2 and a driving component for driving the barrel to rotate, and the discharge box is provided with a discharge component for discharging the coating outward.

[0007] By adopting the above technical solution, when the paint needs to be ground, the paint and the grinding balls are added into the cylinder together, and then the opening of the cylinder is closed, and then the motor is started to drive the output end of the motor to drive the rotating frame 2 to rotate, and at the same time, the rotating frame 2 drives the rotating frame 1 to rotate through the connecting rod. At this time, the rotating frame 1 drives the discharge box and the cylinder to rotate, and drives the grinding balls in the cylinder to grind the paint. After the paint is ground, the motor is driven to stop rotating, and then the direction of the rotating frame 2 is restricted by the limiting component so that the rotating frame 2 and the bottom of the machine body are arranged perpendicular to each other. Then, the cylinder is driven to rotate by the driving component, and at the same time, the cylinder drives the discharging box and the rotating frame 1 to rotate. At this time, the cylinder and the discharging box are inclined, so that the paint and grinding balls in the cylinder are moved toward the direction of the discharging box, and then the paint and grinding balls in the cylinder can be taken out through the discharging component, thereby achieving the effect of being able to take out the paint and grinding balls in the cylinder without the need for the staff to use tools, reducing the operating steps of the staff and improving work efficiency.

[0008] The present invention is further configured as follows: the limiting component includes a movable plate, a sliding groove for sliding the movable plate is provided on the machine body, a cylinder is fixedly connected to the bottom of the sliding groove, the output end of the cylinder is fixedly connected to the movable plate, and the top of the movable plate is fixedly connected to the limiting plate. When the rotating frame 2 and the limiting plate contact each other, the rotating frame 2 and the top of the movable plate are arranged perpendicular to each other and the cylinder is in an extended state at this time, and a limiting member for limiting the rotation of the rotating frame 2 is provided on the movable plate.

[0009] When the cam is in the forward direction and the cam is in the forward direction, the cylinder is driven to stop rotating, and the cylinder is started to drive the output end of the cylinder to drive the movable plate to start moving upward along the slide groove, and the movable plate drives the limit plate to move upward. After the movable plate moves to the specified area, the cylinder is driven to stop extending, and then the motor is started again to drive the motor to drive the rotating frame to rotate. At the same time, the rotating frame will contact the side wall of the limit plate and fix the position of the rotating frame by the limit member. At this time, the rotating frame and the top of the movable plate are arranged perpendicular to each other, and then the motor is turned off, so as to achieve the effect of limiting the direction of the rotating frame. In subsequent operations, the cylinder can be rotated upward to avoid affecting the subsequent normal use. When the rotating frame needs to be driven to rotate again, it is only necessary to drive the cylinder to drive the movable plate to its original position, drive the limit plate and the rotating frame to separate from each other, and the rotating frame can rotate without restriction.

[0010] The utility model is further configured as follows: the limiting member includes a wedge block, a groove is provided on the movable plate, the wedge block and the groove are connected by a spring, when the spring is in a natural state, the inclined surface of the wedge block protrudes from the notch of the groove, there is a gap between the wedge block and the limiting plate, and when the rotating frame 2 is located at the spacing, the two sides of the rotating frame 2 are respectively in contact with the limiting plate and the side walls of the wedge block.

[0011] By adopting the above-mentioned limiting member, when the motor drives the rotating frame 2 to rotate, the rotating frame 2 will contact the inclined surface of the wedge block, and then the motor continues to apply force to the rotating frame 2. At this time, the wedge block will be affected by its own inclined surface and the force applied by the rotating frame 2, and begin to move downward along the groove, while driving the spring to deform and compress. At this time, the rotating frame 2 can continue to rotate. When the rotating frame 2 rotates to the spacing, the spring loses its restriction and begins to deform and recover, driving the wedge block to move upward, and driving the two sides of the rotating frame 2 to contact the limit plate and the side wall of the wedge block respectively. At this time, the rotating frame 2 is affected by the limit plate and the wedge block and cannot rotate, thereby achieving the effect of fixing the rotating frame 2.

[0012] The utility model is further configured as follows: the driving assembly includes a hydraulic cylinder, the output end of the hydraulic cylinder is fixedly connected to a placement frame, the placement frame and the bottom of the cylinder are in contact with each other, and when the hydraulic cylinder is in a retracted state, the cylinder is horizontally arranged.

[0013] By adopting the above-mentioned driving assembly, when it is necessary to drive the cylinder to rotate upward, the hydraulic cylinder is started, and the output end of the hydraulic cylinder is driven to drive the placement frame to move upward. At the same time, the placement frame drives it to rotate upward and causes the cylinder to tilt, thereby achieving the effect of driving the cylinder to rotate upward.

[0014] The utility model is further configured as follows: a limiting ring is fixedly connected to a side of the cylinder away from the discharge box, and a distance is provided between the limiting ring and the placement frame.

[0015] By adopting the above technical solution, the problem of the placement frame and the cylinder being separated from each other can be avoided when the placement frame is moving, thereby avoiding affecting normal use.

[0017] By adopting the above-mentioned discharge assembly, when the paint and grinding balls need to be taken out after grinding, the staff can place a basin at the discharge port, and then drive the electric push rod to start retracting. At the same time, the electric push rod drives the moving block to move downward and separate from the rotating plate. At this time, the rotating plate loses its restriction and begins to rotate downward under the influence of its own gravity. At the same time, the baffle loses the restriction of the rotating plate, and because the discharge box is in an inclined state, the baffle will be affected by its own gravity and begin to rotate, and drive the baffle and the discharge port to separate from each other. At this time, the paint and grinding balls in the cylinder will be discharged outward through the discharge port and fall into the basin, thereby achieving the effect of driving the paint and grinding balls to be discharged outward.

[0018] The utility model is further configured as follows: a fixed rod is fixedly connected between the discharge box and the rotating frame, a support rod is fixedly connected to the machine body, a support frame is fixedly connected to the support rod, the support frame and the side walls of the fixed rod are in contact with each other and there is a distance between the two sides and the discharge box and the rotating frame.

[0019] By adopting the above technical solution, the supporting effect of the cylinder on the machine body can be improved and the stability of the support frame can be improved.

[0020] To sum up, the utility model has the following beneficial effects: after the paint is ground, the motor is driven to stop rotating, and then the direction of the rotating frame 2 is restricted by the limiting component, so that the rotating frame 2 and the bottom of the machine body are arranged perpendicular to each other, and then the cylinder is driven to rotate by the driving component, and at the same time the cylinder drives the discharge box and the rotating frame 1 to rotate. At this time, the cylinder and the discharge box are arranged at an angle, so that the paint and grinding balls in the cylinder are moved toward the discharge box, and then the paint and grinding balls in the cylinder can be taken out through the discharge component, thereby achieving the effect of being able to take out the paint and grinding balls in the cylinder without the staff using tools, reducing the staff's operating steps and improving work efficiency.

[0030] A grinding device for producing salt spray resistant coatings, such as Figure 1-Figure 5As shown, it includes a body 1 and a cylinder 2 and a motor 3 connected to each other. The side wall of the cylinder 2 is fixedly connected to a discharge box 4 that is in conduction with the cylinder 2. The side of the discharge box 4 away from the cylinder 2 is fixedly connected to a rotating frame 1 5. The inner wall of the rotating frame 1 5 is provided with a connecting rod 6 arranged in a cross shape. Two ends of the connecting rod 6 are rotatably connected to the rotating frame 1 5, and the other two ends are rotatably connected to a rotating frame 2 7. The output end of the motor 3 is fixedly connected to the rotating frame 2 7. A limiting component for limiting the direction of the rotating frame 2 7 and a driving component for driving the cylinder 2 to rotate are provided on the body 1. A discharge component for discharging the paint outward is provided in the discharge box 4. When the paint needs to be ground, the paint and grinding balls are added into the cylinder 2 together, and then the opening of the cylinder 2 is closed. Then the motor 3 is started to drive the output end of the motor 3 to drive the rotating frame 2 7 to rotate. At the same time, the rotating frame 2 7 is connected The connecting rod 6 drives the rotating frame 1 5 to rotate. At this time, the rotating frame 1 5 drives the discharge box 4 and the cylinder 2 to rotate, and drives the grinding balls in the cylinder 2 to grind the paint. After the paint is ground, the motor 3 is driven to stop rotating. Then, the direction of the rotating frame 2 7 is limited by the limiting component, so that the rotating frame 2 7 and the bottom of the body 1 are set perpendicular to each other. Then, the cylinder 2 is driven to rotate by the driving component. At the same time, the cylinder 2 drives the discharge box 4 and the rotating frame 1 5 to rotate. At this time, the cylinder 2 and the discharge box 4 are tilted, so that the paint and grinding balls in the cylinder 2 move toward the discharge box 4, and then the paint and grinding balls in the cylinder 2 can be taken out through the discharging component, thereby achieving the effect of being able to take out the paint and grinding balls in the cylinder 2 without the staff using tools, reducing the staff's operating steps and improving work efficiency.

[0031] like Figure 1-Figure 4 As shown, the limiting assembly includes a movable plate 8, a slide groove 9 for the movable plate 8 to slide is provided on the body 1, a cylinder 10 is fixedly connected to the bottom of the slide groove 9, the output end of the cylinder 10 is fixedly connected to the movable plate 8, and the top of the movable plate 8 is fixedly connected to the limiting plate 11. When the rotating frame 2 7 and the limiting plate 11 contact each other, the rotating frame 2 7 and the top of the movable plate 8 are arranged perpendicular to each other and the cylinder 10 is in an extended state at this time. A limiting member for limiting the rotation of the rotating frame 2 7 is provided on the movable plate 8, a groove 13 is provided on the movable plate 8, and the wedge block 12 and the groove 13 are connected by a spring 14. When the spring 14 is in a natural state, the inclined surface of the wedge block 12 protrudes from the notch of the groove 13, and there is a gap between the wedge block 12 and the limiting plate 11. When the rotating frame 2 7 is located at the spacing, the two sides of the rotating frame 2 7 respectively fit together with the side walls of the limiting plate 11 and the wedge block 12.

[0032] When it is necessary to limit the direction of the rotating frame 2 7, the driving motor 3 stops rotating, and then the cylinder 10 is started, and the output end of the cylinder 10 is driven to drive the movable plate 8 to start moving upward along the slide groove 9. At the same time, the movable plate 8 drives the limit plate 11 to move upward. After the movable plate 8 moves to the specified area, the cylinder 10 is driven to stop extending, and then the motor 3 is started again to drive the motor 3 to drive the rotating frame 2 7 to rotate. The rotating frame 2 7 will contact the inclined surface of the wedge block 12, and then the motor 3 continues to apply a force to the rotating frame 2 7. At this time, the wedge block 12 will be affected by its own inclined surface and the force applied by the rotating frame 2 7, and start to move downward along the groove 13, while driving the spring 14 to deform and compress. At this time, the rotating frame 2 7 can continue to rotate. When the rotating frame 2 7 rotates to the interval When the distance is at the point where the spring 14 loses its restriction and begins to deform and recover, it drives the wedge block 12 to move upward, and drives the two sides of the rotating frame 2 7 to contact the limit plates 11 and the side walls of the wedge block 12 respectively. At this time, the rotating frame 2 7 is affected by the limit plates 11 and the wedge blocks 12 and cannot rotate. At the same time, the rotating frame 2 7 and the tops of the movable plate 8 are arranged perpendicular to each other, and then the motor 3 is turned off to achieve the effect of limiting the direction of the rotating frame 2 7, so that in subsequent operations, the cylinder 2 can be rotated upward to avoid affecting the subsequent normal use. When it is necessary to drive the rotating frame 2 7 to rotate again, it is only necessary to drive the cylinder 10 to drive the movable plate 8 to its original position, drive the limit plates 11 and the rotating frame 2 7 to separate from each other, and the rotating frame 2 7 loses its restriction and can rotate.

[0033] like Figure 2 and Figure 3 As shown, the driving assembly includes a hydraulic cylinder 15, and the output end of the hydraulic cylinder 15 is fixedly connected to a placement frame 16 to prevent the placement frame 16 and the bottom of the cylinder 2 from contacting each other. When the hydraulic cylinder 15 is in a retracted state, the cylinder 2 is horizontally arranged. When it is necessary to drive the cylinder 2 to rotate upward, the hydraulic cylinder 15 is started to drive the output end of the hydraulic cylinder 15 to drive the placement frame 16 to move upward. At the same time, the placement frame 16 drives and rotates upward at the same time, and causes the cylinder 2 to tilt, thereby achieving the effect of driving the cylinder 2 to rotate upward. The side of the cylinder 2 away from the discharge box 4 is fixedly connected to a limiting ring 17, and there is a distance between the limiting ring 17 and the placement frame 16, which can avoid the problem of separation of the placement frame 16 and the cylinder 2 when the placement frame 16 moves, thereby avoiding affecting normal use.

[0034] like Figure 2 and Figure 3As shown, the discharging assembly includes a baffle 18 rotatably connected to the inner side wall of the discharging box 4, a discharging port 19 is opened on the side wall of the discharging box 4, a rotating plate 20 is rotatably connected in the discharging box 4, the rotating plate 20 is inclined and contacts the side wall of the baffle 18, and the side of the discharging box 4 away from the cylinder 2 is fixedly connected to an electric push rod 21, and the output end of the electric push rod 21 is fixedly connected to a moving block 22, and the moving block 22 and the rotating plate 20 contact each other. When the electric push rod 21 is in the most extended state, the rotating plate 20 and the baffle 18 abut against each other, and at this time, the baffle 18 and the side wall of the discharging port 19 contact each other. When the paint and grinding balls after grinding need to be taken out, the staff A basin can be placed at the discharge port 19, and then the electric push rod 21 is driven to start retracting. At the same time, the electric push rod 21 drives the moving block 22 to move downward and separate from the rotating plate 20. At this time, the rotating plate 20 loses the restriction and begins to rotate downward under the influence of its own gravity. At the same time, the baffle 18 loses the restriction of the rotating plate 20, and because the discharge box 4 is in an inclined state, the baffle 18 will be affected by its own gravity and begin to rotate, and drive the baffle 18 and the discharge port 19 to separate from each other. At this time, the paint and grinding balls in the cylinder 2 will be discharged outward through the discharge port 19 and fall into the basin, thereby achieving the effect of driving the paint and grinding balls to be discharged outward.

[0035] like Figure 2 and Figure 5 As shown, a fixed rod 23 is fixedly connected between the discharge box 4 and the rotating frame 5, a support rod 25 is fixedly connected to the machine body 1, and a support frame 24 is fixedly connected to the support rod 25. The side walls of the support frame 24 and the fixed rod 23 are in contact with each other and there is a distance between the two sides and the discharge box 4 and the rotating frame 5 respectively, which can improve the supporting effect of the cylinder 2 on the machine body 1 and improve the stability of the support frame 24.

[0036] The working principle of the present invention is as follows: when it is necessary to grind the paint, the paint and the grinding balls are added into the cylinder 2 together, and then the opening of the cylinder 2 is closed, and then the motor 3 is started to drive the output end of the motor 3 to drive the rotating frame 2 7 to rotate, and at the same time, the rotating frame 2 7 drives the rotating frame 1 5 to rotate through the connecting rod 6. At this time, the rotating frame 1 5 drives the discharge box 4 and the cylinder 2 to rotate, and drives the grinding balls in the cylinder 2 to grind the paint. After the paint is ground, the motor 3 is driven to stop rotating, and then the cylinder 10 is started, and the output end of the cylinder 10 is driven to drive the movable plate 8 to start moving upward along the slide 9. At the same time, the movable plate 8 drives the limit plate 11 to move upward. After the movable plate 8 moves to the designated area, the cylinder 10 is driven to stop extending, and then the motor 3 is started again to drive the motor 3 Drive the rotating frame 2 7 to rotate, and the rotating frame 2 7 will contact the inclined surface of the wedge block 12, and then the motor 3 will continue to apply force to the rotating frame 2 7. At this time, the wedge block 12 will be affected by its own inclined surface and the force applied by the rotating frame 2 7, and will begin to move downward along the groove 13, while driving the spring 14 to deform and compress. At this time, the rotating frame 2 7 can continue to rotate. When the rotating frame 2 7 rotates to the spacing, the spring 14 loses its restriction and begins to deform and recover, and drives the wedge block 12 to move upward, and drives the two sides of the rotating frame 2 7 to contact the limit plate 11 and the side walls of the wedge block 12 respectively. At this time, the rotating frame 2 7 is affected by the limit plate 11 and the wedge block 12 and cannot rotate. At the same time, the rotating frame 2 7 and the top of the movable plate 8 are set perpendicular to each other, and then the motor 3 is turned off.

[0037] After the rotating frame 2 7 is fixed, the hydraulic cylinder 15 is started, and the output end of the hydraulic cylinder 15 is driven to drive the placing frame 16 to move upward, and the placing frame 16 is driven to rotate upward at the same time, and the cylinder 2 is tilted, so that the paint and grinding balls in the cylinder 2 are moved toward the discharge box 4. Then the staff can place the basin at the discharge port 19, and then drive the electric push rod 21 to start retracting. At the same time, the electric push rod 21 drives the moving block 22 to move. At this time, the rotating plate 20 loses its restriction and begins to rotate under the influence of its own gravity. At the same time, the baffle 18 loses the restriction of the rotating plate 20 and begins to rotate under the influence of its own gravity, and drives the baffle 18 and the discharge port 19 to separate from each other. At this time, the paint and grinding balls in the cylinder 2 will be discharged outward through the discharge port 19 and fall into the basin, thereby achieving the effect of being able to take out the paint and grinding balls in the cylinder 2 without the staff using tools, reducing the staff's operating steps and improving work efficiency.
