[0048] The electric roller is a component applied to an industrial automatic conveying system, which can provide continuous or intermittent power conveying. The electric roller is widely used in the fields of modern logistics, manufacturing, etc. due to its compact structure, simple installation, stable operation and energy-saving and environment-friendly characteristics, for example, applied in a roller conveying line.

[0049] In the related art, the electric roller includes a roller motor, a speed reducer and a barrel, the roller motor is connected with an input shaft of the speed reducer, the roller motor and the speed reducer are sleeved in the barrel, and an output shaft of the speed reducer is fixedly connected with another side electric roller mounting frame. After the roller motor is started, the shell of the roller motor and the shell of the speed reducer drive the barrel to rotate.

[0050] However, this kind of way has the problem of not easy to install when assembling.

[0051] In order to solve the above problems, the embodiments of the present application provide an extrusion type electric roller and a conveying system, which will be described in detail below in combination with the drawings of the specification.

[0052] FIG. 1 is a structural schematic diagram of an extrusion type electric roller provided by the embodiments of the present application; FIG. 2 is a partial sectional view of the extrusion type electric roller provided by the embodiments of the present application; and FIG. 3 is an enlarged view of the sectional view in FIG. 2.

[0053] In a first aspect, referring to FIGS. 1-3, embodiments of the present application provide an extrusion type electric roller, which includes a roller body 100, a roller motor 200, a speed reducer 300, and an adjustable connecting assembly 400. The roller body 100 is a hollow cylinder configured to carry and transport goods. The roller motor 200, the speed reducer 300, and the adjustable connecting assembly 400 are all arranged in the roller body 100. The roller motor 200 is connected to the roller body 100, the motor housing 220 of the roller motor 200 has a certain gap with the roller body 100, and the roller 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 connecting assembly 400, and the adjustable connecting assembly 400 is fixedly connected to the roller body 100.

[0054] It can be understood that the speed reducer 300 can convert the high rotating speed of the rotating shaft 210 of the roller motor 200 into low rotating speed. When the roller motor 200 is started, the rotating shaft 210 drives the speed reducer 300 to work, and the output end of the speed reducer 300 drives the roller body 100 to rotate through the adjustable connecting assembly 400. Since the roller motor 200 and the speed reducer 300 are fixedly connected to the roller body 100 through the adjustable connecting assembly 400, the relative movement between the roller motor 200, the speed reducer 300, and the roller body 100 can be avoided, and the stable transportation of the roller body 100 can be ensured. 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 rotating speed of the output shaft 340 of the speed reducer 300 is less than that of the input shaft.

[0055] As shown in FIGS. 2 and 3, optionally, the extrusion type electric roller further includes an end cover 800, a rotating bearing, a mandrel 500, and a motor mounting seat 600. The end cover 800 is fixedly installed at the end of the roller body 100, and the rotating bearing is arranged in the end cover 800. The 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 arranged in the roller body 100. The mandrel 500 is arranged in the rotating bearing, one end of the mandrel 500 is fixedly connected to the motor mounting seat 600 opposite to the roller motor 200, and the other end of the mandrel 500 extends from the inside of the roller body 100 to the outside of the roller body 100.

[0057] In the first direction, the first adjusting member 410, the extruding member 420 and the second adjusting member 430 are sequentially arranged in the barrel 100, the first adjusting member 410 is connected with the output end of the speed reducer 300, the locking member 440 penetrates the second adjusting member 430, the extruding member 420 and the first adjusting member 410 in sequence; the locking member 440 is configured to control the distance between the first adjusting member 410 and the second adjusting member 430, so as to control the extruding member 420 extruding on the barrel 100. It should be noted that the first direction is shown as the x direction in FIG. 3. When the locking member 440 drives the first adjusting member 410 and the second adjusting member 430 to move towards each other, the distance between them gradually decreases, and the extruding member 420 is gradually extruded on the inner wall of the barrel 100 under the extrusion of the first adjusting member 410 and the second adjusting member 430, and then the extruding member 420 and the inner wall of the barrel 100 have a large friction force, thereby realizing the connection with the barrel 100. It should be noted that at least one of the first adjusting member 410 and the second adjusting member 430 can move in the barrel 100.

[0058] In some examples, the adjustable connection assembly 400 further comprises a docking member 450, the docking member 450 is connected with the first adjusting member 410, the output end of the speed reducer 300 is connected with the docking member 450, the locking member 440 penetrates the second adjusting member 430, the extruding member 420 and the docking member 450 in sequence, and the locking member 440 controls the distance between the first adjusting member 410 and the second adjusting member 430 through the docking member 450. Optionally, a through hole is formed in the middle position of the first adjusting member 410, the docking member 450 is cylindrical and has a boss near one end close to the speed reducer 300, and the boss is clamped on the first adjusting member 410. The docking member 450 is fitted in 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 through a key. That is, a key is arranged on the docking member 450, a key groove is formed in the corresponding position of the first adjusting member 410, and the key and the key groove are matched to realize the key connection of the docking member 450 and the first adjusting member 410; or a key is arranged on the first adjusting member, and a key groove is formed in the corresponding position of the docking member 450, and the key and the key groove are matched to realize the key connection of the docking member 450 and the first adjusting member 410.

[0059] In addition, one end of the abutting piece 450 is sleeved on the output end of the speed reducer 300, and the other end is connected with the locking piece 440. Under the action of the abutting piece 450, when the locking piece 440 acts, the locking piece 440 controls the distance between the first adjusting piece 410 and the second adjusting piece 430 to gradually decrease or increase. That is, when the locking piece 440 moves in the first direction x direction, the abutting piece 450 will be moved, because the abutting piece 450 is connected with the first adjusting piece 410, the abutting piece 450 will drive the first adjusting piece 410 to move in the first direction x direction towards the direction of approaching or moving away from the second adjusting piece 430, so as to adjust the distance between the first adjusting piece 410 and the second adjusting piece 430.

[0060] In some examples, the extrusion piece 420 is configured as an elastic piece; the locking piece 440 is configured as a bolt-nut assembly. That is to say, when the extrusion piece 420 is extruded by the first adjusting piece 410 and the second adjusting piece 430, the radial dimension of the extrusion piece 420 increases, so as to be tightly extruded on the inner wall of the cylinder body 100, and the connection with the cylinder body 100 is realized. The first adjusting piece 410 and the second adjusting piece 430 can be annular metal pieces with openings.

[0061] In addition, optionally, the adjustable connection assembly 400 further comprises a supporting piece 460, the supporting piece 460 is coaxially arranged with the extrusion piece 420, and the supporting piece 460 is arranged in the extrusion piece 420. The dimension of the extrusion piece 420 along the first direction is greater than the dimension of the supporting piece 460 along the first direction, and the locking piece 440 penetrates through the supporting piece 460 and is connected with the first adjusting piece 410. It can be understood that, because the supporting piece 460 is sleeved in the extrusion piece 420, the supporting force can be provided for the extrusion piece 420, the stability of the extrusion piece 420 as a whole is improved, and it is ensured that the extrusion piece 420 can be in close contact with the cylinder body 100. Optionally, the supporting piece 460 is supported by a material with a relatively hard material, 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 is formed in the bottom wall for the locking piece 440 to pass through.
