Description

Technical Field

[0001] This utility model relates to the field of metering equipment technology, and in particular to an anti-adhesion metering roller. Background Technology

[0002] Metering rollers are cylindrical equipment components widely used in industrial production. They are mainly used to accurately measure and control the amount of material passing through, and are commonly found in the production processes of industries such as coatings, inks, adhesives, and plastics. When used in conjunction with other equipment, metering rollers play an irreplaceable role in ensuring product quality stability, improving production efficiency, and reducing material waste.

[0003] Because materials of different viscosities require different gaps when passing through metering rollers, existing metering rollers cannot adjust the gap width and cannot adapt to materials of various viscosities, resulting in problems such as material accumulation, dripping, and uneven coating. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-adhesion metering roller, which aims to improve the problem that metering rollers cannot adapt to materials of various viscosities.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-adhesion metering roller, comprising: Two control frames are provided, with a base plate fixedly connected to the bottom of each control frame, a fixing plate fixedly connected to the top of each base plate, a second motor fixedly connected to the right side of each fixing plate, an extrusion assembly provided on the inner wall of each control frame, a cleaning assembly provided inside each control frame, and a metering roller assembly provided between the two control frames. Two universal joints are provided, each of which includes a first connecting block. The first connecting block on the left is fixedly disposed between itself and the output end of the second motor. A universal joint is rotatably connected to the right side of each of the two first connecting blocks.

[0007] Preferably, the extension assembly includes a rotating cover, which is fixedly connected to a second connecting block on the left side. A rotating rod is slidably connected inside the second connecting block, and the rotating rod is fixedly connected to a universal joint on the right side.

[0008] Preferably, the extrusion assembly includes two sliding members, both of which are slidably connected to two control frames. The left sliding member is rotatably connected to the right second connecting block. Two elastic members are fixedly connected to the top of each of the two sliding members, and the four elastic members are fixedly connected to the two control frames.

[0009] Preferably, the metering roller assembly includes a lower metering roller, which is rotatably connected to two control frames. A third motor is fixedly connected to the left side of the control frame on the left side. The lower metering roller is fixedly connected to the output end of the third motor. An upper metering roller is provided on the top of the lower metering roller. The upper metering roller is fixedly connected to the second connecting block on the right side. The upper metering roller is rotatably connected to the sliding member on the right side.

[0010] Preferably, the first connecting block and the second connecting block have the same shape, and the universal joint is a cross-shaped rod.

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Reference Figure 1 and Figure 2 One embodiment of this utility model is an anti-adhesion metering roller, comprising: Two control frames 9, with a base plate 1 fixedly connected to the bottom of the two control frames 9, a fixing plate 7 fixedly connected to the top of the base plate 1, a second motor 8 fixedly connected to the right side of the fixing plate 7, an extrusion assembly 5 provided on the inner wall of the two control frames 9, a cleaning assembly 4 provided inside the two control frames 9, and a metering roller assembly 6 provided between the two control frames 9. Two universal components 2, each of which includes a first connecting block 201. The first connecting block 201 on the left is fixedly disposed between the output end of the second motor 8. Universal parts 202 are rotatably connected to the right side of each of the two first connecting blocks 201. A second connecting block 203 is rotatably connected to the surface of each of the two universal parts 202. An extension component 3 is disposed on the right side of the second connecting block 203 on the left.

[0019] Specifically, the two control frames 9 are symmetrically distributed, and their bottoms are connected to the base plate 1 by bolts to prevent the device from shaking or tipping over. The base plate 1 bears the weight of the entire device, and the fixing plate 7 is vertically fixed to the top of the base plate 1 to provide mounting for the second motor 8. The right side of the first connecting block 201 in both universal components 2 is connected to the universal joint 202 through a rotating joint. The two universal joints 202 can transmit the force from the first connecting block 201, so that the universal joint 202 can rotate in any angle direction. The two universal joints 202 are also connected to the second connecting block 203 through a rotating joint, and transmit the force of the first connecting block 201 to the second connecting block 203, so that the second connecting block 203 can freely change direction in space following the rotation of the universal joints 202. The two universal joints 2, the extension component 3 and the extrusion component 5 cooperate with each other to enable the upper metering roller 601 to move vertically, thereby solving the problem that the metering roller cannot adapt to materials of various viscosities.

[0020] Reference Figure 1 and Figure 3 The cleaning component 4 includes a cleaning element 403, which is slidably connected to two control frames 9. A first motor 401 is fixedly connected to the rear side of the right control frame 9. A threaded rod 402 is fixedly provided at the output end of the first motor 401. The threaded rod 402 is threadedly connected to the cleaning element 403, and the threaded rod 402 is rotatably connected to the right control frame 9.

[0021] Specifically, the cleaning component 403 is slidably connected to the two control frames 9, so that the cleaning component 403 can move horizontally under the control of the control frames 9. The control frame 9 on the right provides an installation position for the first motor 401, and one end of the threaded rod 402 is rotatably connected to the control frame 9 through a bearing. When cleaning of the metering roller assembly 6 is required, the first motor 401 is started. The output shaft of the motor drives the threaded rod 402 to rotate synchronously. Because the threaded rod 402 is threadedly connected to the cleaning component 403, the rotation of the threaded rod 402 is converted into linear motion of the cleaning component 403 along the axial direction of the threaded rod 402, thereby cleaning the metering roller assembly 6 and solving the problem of decreased metering accuracy caused by material adhering to the surface of the metering roller.

[0022] Reference Figure 4 The extension assembly 3 includes a rotating cover 301, which is fixedly connected to the second connecting block 203 on the left. A rotating rod 302 is slidably connected inside the second connecting block 203, and the rotating rod 302 is fixedly connected to the universal joint 202 on the right.

[0023] Specifically, the rotating cover 301 is connected to the second connecting block 203 on the left by welding to ensure that the rotating cover 301 can stably receive the motion and power transmission from the second connecting block 203. The rotating cover 301 is slidably connected to the rotating rod 302, so that the rotating rod 302 can move axially inside the second connecting block 203.

[0024] Reference Figure 1The extrusion assembly 5 includes two sliding members 501, both of which are slidably connected to two control frames 9. The left sliding member 501 is rotatably connected to the right second connecting block 203. Two elastic members 502 are fixedly connected to the top of each of the two sliding members 501. The four elastic members 502 are fixedly connected to the two control frames 9.

[0025] Specifically, the inner wall of the control frame 9 is provided with a sliding groove that adapts to two sliding members 50. The sliding members 50 slide up and down in the sliding groove of the control frame 9. The left sliding member 501 is rotatably connected to the right second connecting block 203, thereby transmitting the movement from the second connecting block 203 and converting the movement of the second connecting block 203 into vertical movement. One end of the two elastic members 502 is fixedly connected to the sliding member 501, and the other end is fixedly connected to the control frame 9, so that the sliding member 501 is elastically reset after movement.

[0026] Reference Figure 1 The metering roller assembly 6 includes a lower metering roller 602, which is rotatably connected to two control frames 9. A third motor 603 is fixedly connected to the left side of the control frame 9 on the left side. The lower metering roller 602 is fixedly connected to the output end of the third motor 603. An upper metering roller 601 is provided on the top of the lower metering roller 602. The upper metering roller 601 is fixedly connected to the second connecting block 203 on the right side. The upper metering roller 601 is rotatably connected to the sliding member 501 on the right side.

[0027] Specifically, the left control frame 9 provides a fixed installation position for the third motor 603. The third motor 603 provides power to the lower metering roller 602. When the third motor 603 starts, it causes the lower metering roller 602 to rotate. The upper metering roller 601 is set on the top of the lower metering roller 602. The lower metering roller 602 and the upper metering roller 601 work together to complete the metering of materials.

[0028] Reference Figure 2 The first connecting block 201 and the second connecting block 203 have the same shape, and the universal joint 202 is a cross-shaped rod.

[0029] Specifically, the first connecting block 201 and the second connecting block 203 have the same shape to ensure the symmetry when the first connecting block 201 and the second connecting block 203 work together. The universal joint 202 is designed as a cross-shaped rod, which allows the universal joint 202 to rotate freely in the horizontal and vertical planes.

[0030] Reference Figure 1 and Figure 3 The first motor 401 is a bidirectional motor, and the cleaning component 403 is a cleaning brush.

[0031] Specifically, the first motor 401 is a bidirectional motor. After the metering work is completed, the first motor 401 is started. When the first motor 401 rotates in the forward direction, its output shaft drives the threaded rod 402 to rotate in the forward direction, which in turn drives the cleaning part 403 to move in the forward direction. When the first motor 401 rotates in the reverse direction, its output shaft drives the threaded rod 402 to rotate in the reverse direction, which in turn drives the shaft of the cleaning component 403 to move in the reverse direction, thereby driving the cleaning component 403 to move axially repeatedly. The cleaning component 403 is a cleaning brush with bristles on both the top and bottom.

[0032] Reference Figure 1 The four elastic elements 502 are springs, and the two sliding elements 501 are square.

[0033] Specifically, the four elastic elements 502 are springs with elastic properties. When subjected to force, they undergo elastic deformation and store elastic potential energy. After the force disappears, they release the elastic potential energy and drive the sliding element 501 to reset.

[0034] Working principle: When measurement is required, the second motor 8 drives the left universal assembly 2 to rotate, the left universal assembly 2 drives the telescopic assembly 3 to rotate, the telescopic assembly 3 drives the right universal assembly 2 to rotate, the right universal assembly 2 drives the upper metering roller 601 to rotate, and at this time the first motor synchronously drives the lower metering roller 602 to rotate. In the universal assembly 2, the first connecting block 201 and the second connecting block 203 can both rotate in the universal joint 202. The control rotating rod 302 can extend and retract within the second connecting block 203. Through the cooperation of the two universal assemblies 2 and the telescopic assembly 3, the upper metering roller 601 has the ability to move vertically while the position of the second motor 8 remains unchanged and its own horizontal position remains unchanged. When materials of different viscosities are metered, they pass through the gap between the upper metering roller 601 and the lower metering roller 602. At this time, the upper metering roller 601 is squeezed and moved upward. The upper metering roller 601 drives 501 to move upward and squeeze the elastic element 502, thus adapting to materials of different viscosities. After the metering is completed, the metering roller will reset under the elastic force of the elastic element 502, waiting for the next metering operation. This solves the problem that the metering roller cannot adapt to materials of various viscosities. After the metering roller completes the material metering work, the first bidirectional motor 401 in the cleaning component 4 is started. The first motor 401 drives the threaded rod 402 to rotate. The threaded rod 402 is threadedly connected to the cleaning component 403 assembly, and the cleaning component 403 is slidably connected to the two control frames 9. Under the control of the two control frames 9, the rotation of the threaded rod 402 will drive the cleaning component 403 to reciprocate linearly along the threaded rod 402 between the two control frames 9. During the reciprocating motion of the cleaning component 403, the surface of the metering roller assembly 6 can be cleaned to remove the material adhering to the surface of the metering roller, thus solving the problem of decreased metering accuracy caused by material adhesion.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
