For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0041] In this application, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over", and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.

[0042] The electric roller is a component applied to industrial automation conveying systems, capable of providing continuous or intermittent power transmission. Due to its characteristics of compact structure, easy installation, stable operation, energy conservation and environmental protection, the electric roller has been widely used in modern logistics, manufacturing and other fields, such as in roller conveyor lines.
[0043] In the related art, the electric roller includes a roller motor, a speed reducer and a cylinder body. The roller motor is connected to the input shaft of the speed reducer. The roller motor and the speed reducer are plugged into the cylinder body. The output shaft of the speed reducer is fixedly connected to the mounting frame of the electric roller on the other side. After the roller motor is started, the housing of the roller motor and the housing of the speed reducer drive the cylinder body to rotate.
[0044] However, in the assembly of this method, there is a problem of difficult installation.
[0045] To solve the above problems, the embodiments of the present application provide an extrusion type electric roller and a conveying system. The solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings of the specification.
[0046] Figure 1 is a schematic structural diagram of an extrusion type electric roller provided by an embodiment of the present application; Figure 2 is a partial cross-sectional view of an extrusion type electric roller provided by an embodiment of the present application; Figure 3 is Figure 2 the enlarged cross-sectional view in
[0047] In the first aspect, as shown in Figures 1 to 3 , the embodiments of the present application provide an extrusion type electric roller, including a cylinder body 100, a roller motor 200, a speed reducer 300 and an adjustable connection assembly 400. Among them, the cylinder body 100 is a cylinder with a hollow space, which can be used to carry and convey goods. The roller motor 200, the speed reducer 300 and the adjustable connection assembly 400 are all arranged inside the cylinder body 100. The roller motor 200 is connected to the cylinder body 100 in a cooperative manner. There is a certain gap between the motor housing 220 of the roller motor 200 and the cylinder body 100, and the cylinder body 100 can rotate around the motor. The input end of the speed reducer 300 is connected to the rotating shaft 210 of the roller motor 200. The output end of the speed reducer 300 is connected to the adjustable connection assembly 400, and the adjustable connection assembly 400 is fixedly connected to the cylinder body 100.
[0048] It can be understood that the speed reducer 300 can convert the high rotational speed output by the rotating shaft 210 of the roller motor 200 into a low rotational speed. When the roller motor 200 starts, its rotating shaft 210 drives the speed reducer 300 to work, and the output end of the speed reducer 300 drives the cylinder body 100 to rotate through the adjustable connection assembly 400. Since the roller motor 200 and the speed reducer 300 are fixedly connected to the cylinder body 100 through the adjustable connection assembly 400, relative movement between the roller motor 200, the speed reducer 300 and the cylinder body 100 can be avoided, ensuring that the cylinder body 100 can stably convey goods. It should be noted that the input end of the speed reducer 300 is the input shaft of the speed reducer 300, and the output end of the speed reducer 300 is the output shaft 340 of the speed reducer 300. The rotational speed of the output shaft 340 of the speed reducer 300 is less than the rotational speed of the input shaft.
[0049] As Figure 2 and Figure 3 shown, exemplarily, the extrusion type electric roller further includes an end cover 800, a rotating bearing, a mandrel 500 and a motor mounting seat 600. Among them, the end cover 800 is fixedly installed at the end of the cylinder body 100, and the rotating bearing is arranged in the end cover 800 in a matching manner. One end of the roller motor 200 away from the speed reducer 300 is fixedly connected to the motor mounting seat 600, and the motor mounting seat 600 and the roller motor 200 are both arranged in the cylinder body 100. The mandrel 500 is installed in the rotating bearing in a matching manner. One end of the mandrel 500 is fixedly connected to the end of the motor mounting seat 600 opposite to the roller motor 200, and the other end of the mandrel 500 extends from inside the cylinder body 100 to outside the cylinder body 100. The part of the mandrel 500 located outside the cylinder body 100 is used for mating installation with the extrusion type electric roller mounting frame.
[0050] Continue to refer to Figure 2 and Figure 3 shown, the adjustable connection assembly 400 includes a first adjusting member 410, an extrusion member 420, a second adjusting member 430 and a locking member 440.
[0051] Along the first direction, the first adjusting member 410, the extrusion member 420 and the second adjusting member 430 are sequentially arranged inside the cylinder body 100. The first adjusting member 410 is connected to the output end of the speed reducer 300, and the locking member 440 sequentially passes through the second adjusting member 430, the extrusion member 420 and is connected to the first adjusting member 410; the locking member 440 is used to control the distance between the first adjusting member 410 and the second adjusting member 430 to control the extrusion of the extrusion member 420 on the cylinder body 100. It should be noted that the first direction is as Figure 3as shown in the x-direction in []. When the locking member 440 drives the first adjusting member 410 and the second adjusting member 430 to move towards each other and the distance between them gradually decreases, the pressing member 420 is gradually pressed against the inner wall of the cylinder 100 under the pressing action of the first adjusting member 410 and the second adjusting member 430. Furthermore, a large frictional force is generated between the pressing member 420 and the inner wall of the cylinder 100, thereby realizing the connection with the cylinder 100. It should be noted that at least one of the first adjusting member 410 and the second adjusting member 430 can move within the cylinder 100.
[0052] In some examples, the adjustable connection assembly 400 further includes a docking member 450. The docking member 450 is connected to the first adjusting member 410, the output end of the reducer 300 is connected to the docking member 450, the locking member 440 sequentially passes through the second adjusting member 430, the pressing member 420 and is connected to the docking member 450. The locking member 440 controls the distance between the first adjusting member 410 and the second adjusting member 430 through the docking member 450. Exemplarily, a through hole is provided at the middle position of the first adjusting member 410. The docking member 450 is cylindrical and has a boss at one end close to the reducer 300. The boss is snap-fitted onto the first adjusting member 410. The docking member 450 is fitted into the through hole of the first adjusting member 410, and the docking member 450 and the first adjusting member 410 can be fixedly connected or connected by a key. Additionally, one end of the docking member 450 is sleeved on the output end of the reducer 300, and the other end is connected to the locking member 440. Under the action of the docking member 450, when the locking member 440 acts, the locking member 440 controls the distance between the first adjusting member 410 and the second adjusting member 430 to gradually decrease or increase.
[0053] In some examples, the pressing member 420 is configured as an elastic member; the locking member 440 is configured as a bolt-nut assembly. That is to say, when the pressing member 420 is pressed by the first adjusting member 410 and the second adjusting member 430, the radial dimension of the pressing member 420 increases, so that it can be tightly pressed against the inner wall of the cylinder 100 to realize the connection with the cylinder 100. Both the first adjusting member 410 and the second adjusting member 430 can be ring-shaped metal members with openings.
[0054] Additionally, by way of example, the adjustable connection assembly 400 further includes a support member 460. The support member 460 is coaxially arranged with the extrusion member 420, and the support member 460 is disposed inside the extrusion member 420. The dimension of the extrusion member 420 in the first direction is greater than the dimension of the support member 460 in the first direction. The locking member 440 passes through the support member 460 and is connected to the first adjusting member 410. It can be understood that since the support member 460 is sleeved inside the extrusion member 420, it can provide a supporting force for the extrusion member 420, improve the overall stability of the extrusion member 420, and ensure that the extrusion member 420 can be in close contact with the cylinder 100. By way of example, the support member 460 is made of a material with a relatively hard texture and has a bottom wall and a side wall. The side wall is arranged along the outer edge of the bottom wall, and the bottom wall and the side wall enclose a hollow space. A through hole for the locking member 440 to pass through is provided on the bottom wall. During specific assembly, the support member 460 abuts against the side wall of the first adjusting member 410 and is buckled on the docking member 450.
[0055] Figure 4 It is a schematic diagram of the adjustable connection assembly 400 of the extrusion type electric roller provided by another embodiment of the present application.
[0056] Referring Figure 4 As shown, in some other examples, the first adjusting member 410 is provided with a frustum 411. The frustum 411 extends in the first direction and its diameter gradually decreases. The extrusion member 420 is disposed between the frustum 411 and the cylinder 100. The second adjusting member 430 controls the extrusion member 420 to be extruded against the frustum 411 and the cylinder 100. By way of example, the extrusion member 420 can be configured as a steel ball. And a plurality of steel balls can be placed between the frustum 411 and the cylinder 100. When the locking member 440 drives the first adjusting member 410 and the second adjusting member 430 to move towards each other and the distance between them decreases, the second adjusting member 430 pushes the steel balls to move. The steel balls tend to move radially under the action of the frustum 411, so as to be tightly connected to the cylinder 100 and achieve a firm connection with the cylinder 100.
[0057] In addition, by way of example, the above-mentioned speed reducer 300 can be a planetary speed reducer 300, which has a speed reducer housing 330, an input shaft, a sun gear 310, planet gears 320 and an output shaft 340. The speed reducer housing 330 is fixedly connected to the roller motor 200. The input shaft is fitted and installed in the speed reducer housing 330. The sun gear 310 is fitted and installed in the input shaft. The sun gear 310 meshes with the planet gears 320. The planet gears 320 are connected to the planet gear carrier, and the planet gear carrier is connected to the output shaft 340. This planetary speed reducer 300 is a prior art in the field, and its internal structure will not be described in detail herein.
[0058] Figure 5 It is a schematic diagram of the structure of the extrusion type electric roller provided by another embodiment of the present application.
[0059] ReferringFigure 5 As shown, in some examples, the extrusion electric roller includes at least one sprocket 700, and at least one sprocket 700 is fixedly connected to the cylinder body 100. For example, one sprocket 700 is fixedly arranged at one end of the extrusion electric roller, or two sprockets 700 can be fixedly and juxtaposed at one end of the extrusion electric roller.
[0060] In other examples, at least one sprocket 700 is arranged at both ends of the extrusion electric roller, and at least one sprocket 700 is fixedly connected to the cylinder body 100. For example, one sprocket 700 is arranged at both ends of the extrusion electric roller, or two sprockets 700 are juxtaposed. When the extrusion electric roller is used as a power roller, the sprockets 700 at both ends thereof are respectively connected to the sprockets at both ends of the non-powered roller, so that the forces at both ends of the non-powered roller are uniform, and thus the rotation is more stable.
[0061] In a second aspect, the embodiments of the present application provide a conveying system, including the extrusion electric roller as in the first aspect. Since this conveying system includes the extrusion electric roller in any of the above technical solutions, it has all the beneficial effects of the extrusion electric roller in any of the above technical solutions, which will not be elaborated here.
[0062] It is easy to understand that those skilled in the art can combine, split, and reorganize the embodiments of the present application based on several embodiments provided by the present application to obtain other embodiments, and these embodiments do not exceed the protection scope of the present application.
[0063] The above specific implementation manners further elaborate the purpose, technical solutions, and beneficial effects of the embodiments of the present application. It should be understood that the above are only the specific implementation manners of the embodiments of the present application, and are not used to limit the protection scope of the embodiments of the present application.
