The roller group 600 is installed on the mounting frame 100 and is in transmission connection with the transmission device 400, so that the roller group 600 can rotate.

[0041] Please refer to Figures 1 to 4 In an embodiment of the present utility model, the sorting module 10 includes a mounting frame 100, a driving device 300, a transmission device 400, and a limiting structure 500. The mounting frame 100 includes a bottom plate 110 and two side plates 120 provided on opposite sides of the bottom plate 110.

The transmission device 400 includes a transmission wheel 410 and a fixed shaft 420. The transmission wheel 410 is rotationally connected to the fixed shaft 420, and the transmission wheel 410 is in transmission connection with the driving wheel 320. The fixed shaft 420 is fixedly installed in the second mounting opening 220.

The limiting structure 500 is used to limit the driving device 300 and the transmission device 400 in the first mounting opening 210 and the second mounting opening 220.

[0042] Specifically, please refer to Figures 1 to 3, the mounting frame 100 includes a bottom plate 110 and two side plates 120 provided on opposite sides of the bottom plate 110. An installation space for installing the driving device 300 and the transmission device 400 of the sorting module 10 is formed between the two side plates 120. The side plates 120 and the bottom plate 110 can be fixedly connected together by screwing, or can be connected together by other means. For the convenience of production and processing, the mounting frame 100 of the present utility model is integrally formed, and it is formed by one-time processing of sheet metal parts. It has a simple structure and is convenient for processing, which can further improve the production efficiency of the mounting frame 100 and reduce the production cost. At the same time, after the mounting frame 100 of the present utility model is processed, no secondary processing is required, and its production and processing process is more convenient, improving the production efficiency. The mounting frame 100 made of sheet metal parts has a relatively low material cost, which also further reduces the cost.

[0043] Please refer to Figure 2 and Figure 4 , the driving device 300 includes a driving motor 310 and a driving wheel 320. The type of the driving motor 310 can be an external rotor motor. The stator shaft 312 is fixedly installed in the first installation port 210 and is relatively fixed at both ends. The motor body 311 is rotatable relative to the stator shaft 312. The driving wheel 320 is connected to the motor body 311. When the motor body 311 rotates relative to the stator shaft 312, the driving wheel 320 will rotate together with the rotation of the motor body 311.

[0044] Please refer to Figure 2 and Figure 4 , the transmission device 400 includes a transmission wheel 410 and a rotating shaft rod. The transmission wheel 410 is rotatably connected to the fixed shaft 420. Specifically, the transmission wheel 410 is sleeved on the fixed shaft 420, and the two can be connected together by bearings to realize the rotation of the transmission wheel 410 relative to the fixed shaft 420. The fixed shaft 420 is fixedly installed in the second installation port 220 and is relatively fixed at both ends.

[0045] Please refer to Figure 1 and Figure 2, Further, the sorting module 10 further includes a roller group 600, the roller group 600 is installed on the mounting frame 100, and is in transmission connection with the transmission wheel 410. Since the transmission wheel 410 is in transmission connection with the driving wheel 320, when the driving device 300 works, the motor body 311 rotates to drive the driving wheel 320 to rotate, the driving wheel 320 rotates to drive the transmission wheel 410 to rotate, and the transmission wheel 410 rotates to further drive the roller group 600 to rotate, so as to convey the goods through the rotation of the roller group 600, and control the conveying direction of the goods through the rotation of the whole sorting module 10, so as to achieve the purpose of sorting the goods. Wherein, the driving wheel 320 and the transmission wheel 410 can be configured as gears, that is, the driving wheel 320 is a driving gear and the transmission wheel 410 is a transmission gear.

[0046] Please refer to Figure 4 and Figure 5 , The limiting structure 500 includes a fixing plate 510 and a first pin 520 and a second pin 530 arranged on the fixing plate 510. The fixing plate 510, the first pin 520 and the second pin 530 are integrally formed, which is convenient for the production and manufacture of the limiting structure 500. In the length direction of the fixing plate 510, the two first pins 520 are arranged at both ends of the fixing plate 510, the second pin 530 is arranged in the middle of the fixing plate 510, and in the width direction of the fixing plate 510, the two first pins 520 are connected to the same side of the fixing plate 510, and the second pin 530 is connected to the other side of the fixing plate 510. Wherein, the first pin 520 is correspondingly inserted into the first mounting opening 210 for limiting and fixing the position of the stator shaft 312, and the second pin 530 is correspondingly inserted into the second mounting opening 220 for limiting and fixing the position of the fixed shaft 420. Through one limiting structure 500, the positions of the stator shaft 312 of the driving device 300 and the fixed shaft 420 of the transmission device 400 are simultaneously limited and fixed, reducing the number of the limiting structures 500 used, with simple and convenient operation, high efficiency, and further reducing the production cost.

[0047] The technical solution of the present utility model simultaneously realizes the common limiting and fixing of the positions of the stator shaft 312 of the driving device 300 and the fixed shaft 420 of the transmission device 400 by adopting one limiting structure 500, reduces the number of the limiting structures 500 used, has simple and convenient operation, high efficiency, and further reduces the production cost.

[0048] Please refer to Figure 2 and Figure 6, in one embodiment, the first mounting opening 210 extends in the up-and-down direction, and the stator shaft 312 abuts against and is limited by the opposite side walls of the first mounting opening 210 in the lateral direction. The second mounting opening 220 extends in the up-and-down direction, and the fixed shaft 420 abuts against and is limited by the opposite side walls of the second mounting opening 220 in the lateral direction. The first pin 520 is disposed in the first mounting opening 210 for limiting the stator shaft 312 in the up-and-down direction, and the second pin 530 is disposed in the second mounting opening 220 for limiting the fixed shaft 420 in the up-and-down direction.

[0049] Specifically, during the process of placing the stator shaft 312 into the first mounting opening 210, the direction of placing the stator shaft 312 is defined as the up-and-down direction. After the stator shaft 312 is installed in the first mounting opening 210, at least a part of the outer surface of the stator shaft 312 abuts against the opposite two side walls of the first mounting opening 210, so that the stator shaft 312 installed in the first mounting opening 210 is limited in the lateral direction. Similarly, after the fixed shaft 420 is installed in the second mounting opening 220, at least a part of the outer surface of the fixed shaft 420 abuts against the opposite two side walls of the second mounting opening 220, so that the stator shaft 312 installed in the second mounting opening 220 is limited in the lateral direction. At the same time, the first pin 520 is correspondingly inserted into the first mounting opening 210 for limiting the stator shaft 312 in the up-and-down direction, and the second pin 530 is correspondingly inserted into the second mounting opening 220 for limiting the fixed shaft 420 in the up-and-down direction.

[0050] Please refer to Figure 1 and Figure 3 , in one embodiment, the first pin 520 is located above the stator shaft 312, and the fixing plate 510 covers the end of the stator shaft 312. The second pin 530 is located above the fixed shaft 420, and the end of the fixed shaft 420 is located below the fixing plate 510. Further, a screw hole is provided at the end of the fixed shaft 420, and a through hole for the screw to pass through is provided at the position of the fixing plate 510 corresponding to the screw hole. The screw passes through the through hole and is screwed with the screw hole to fix the position of the limiting structure 500, and the connection method is simple. At the same time, since the driving motor 310 needs to lead out the wire 800 to be electrically connected to the outside, and the main body of the driving motor 310 rotates during operation, the wire 800 can be led out from the end of the stator shaft 312 of the driving motor 310. Moreover, by arranging the second pin 530 above the fixed shaft 420 and the end of the fixed shaft 420 below the fixing plate 510, it can be ensured that the fixing plate 510 does not block the end of the fixed shaft 420, that is, does not block the outgoing line of the wire 800, which is convenient for the routing of the wire 800.

[0051] Please refer to Figure 6, in one embodiment, the first mounting opening 210 includes a first sliding inlet 211 and a first limiting opening 212 that communicate with each other. The first sliding inlet 211 extends in the vertical direction, the first limiting opening 212 extends in the horizontal direction, the extending directions of the first sliding inlet 211 and the first limiting opening 212 intersect, and the extending length of the first limiting opening 212 is greater than the width of the first sliding inlet 211. The first pin 520 is disposed in the first limiting opening 212; and / or,

[0052] The second mounting opening 220 includes a second sliding inlet 221 and a second limiting opening 222 that communicate with each other. The second sliding inlet 221 extends in the vertical direction, the second limiting opening 222 extends in the horizontal direction, the extending directions of the second sliding inlet 221 and the second limiting opening 222 intersect, and the extending length of the second limiting opening 222 is greater than the width of the second sliding inlet 221. The second pin 530 is disposed in the second limiting opening 222.

[0053] Specifically, when installing the drive motor 310, first, the two ends of the stator shaft 312 are respectively inserted into the first sliding inlet 211 correspondingly, and then the two ends of the stator shaft 312 are moved downward from the first sliding inlet 211 to the bottom of the first sliding inlet 211 and are located below the first limiting opening 212. Since the extending direction of the first sliding inlet 211 and the direction of the second extending opening intersect, in this embodiment, the first sliding inlet 211 extends in the vertical direction, the first limiting opening 212 extends in the horizontal direction, and the extending length of the first limiting opening 212 is greater than the width of the first sliding inlet 211. Thus, by disposing the first pin 520 in the first limiting opening 212, the end of the stator shaft 312 disposed at the bottom of the first sliding inlet 211 and located below the first limiting opening 212 is limited by the first pin 520.

[0054] Similarly, when installing the transmission device 400, first, the two ends of the fixed shaft 420 are respectively inserted into the second sliding inlet 221 correspondingly, and then the two ends of the fixed shaft 420 are moved downward from the second sliding inlet 221 to the bottom of the second sliding inlet 221 and are located below the second limiting opening 222. Since the extending direction of the second sliding inlet 221 and the direction of the second extending opening intersect, in this embodiment, the second sliding inlet 221 extends in the vertical direction, the second limiting opening 222 extends in the horizontal direction, and the extending length of the second limiting opening 222 is greater than the width of the second sliding inlet 221. Thus, by disposing the second pin 530 in the second limiting opening 222, the end of the fixed shaft 420 disposed at the bottom of the second sliding inlet 221 and located below the second limiting opening 222 is limited by the second pin 530.

[0055] It should be noted that when installing the driving device 300 and the transmission device 400, the driving device 300 should be installed into the first installation opening 210 first, and then the transmission device 400 should be installed into the second installation opening 220, and the driving wheel 320 of the driving device 300 and the transmission wheel 410 of the transmission device 400 should be in driving connection. Among them, the driving wheel 320 and the transmission wheel 410 can be configured as gear structures and mesh with each other. Finally, the positions of the shafts of the driving device 300 and the transmission device 400 are limited and fixed simultaneously through the limiting structure 500, so as to limit and fix the overall transmission device 400 and the driving device 300.

[0056] In an embodiment, the length of the first pin 520 extending into the first limiting opening 212 is greater than the thickness of the side plate 120, and the length of the second pin 530 extending into the second limiting opening 222 is greater than the thickness of the side plate 120. With such a setting, the stability of the first pin 520 and the second pin 530 in limiting the driving device 300 and the transmission device 400 respectively can be ensured, and the too short first pin 520 or second pin 530 can be prevented from disengaging from the first limiting opening 212 or the second limiting opening 222.

[0057] Please refer to Figure 3 , in an embodiment, the driving wheel 320 and the transmission wheel 410 are both configured as gears and mesh with each other. Since the transmission wheel 410 also needs to mesh and drive connect with the roller group 600, therefore, to improve the driving efficiency of the driving device 300, the number of the transmission devices 400 is set to two, and the roller group 600 includes 4 rollers. In this way, one driving device 300 drives two transmission devices 400, and the two transmission devices 400 drive 4 rollers to rotate, so as to realize the conveying of goods. At the same time, since when installing the driving device 300 and the transmission device 400, the driving device 300 should be installed into the first installation opening 210 first, and then the transmission device 400 should be installed into the second installation opening 220, correspondingly, the number of the second installation openings 220 is two. In the up-down direction, the two second installation openings 220 are arranged on the opposite sides of the first installation opening 210, and in the horizontal direction, the two second installation openings 220 are arranged on the side of the first installation opening 210 away from the bottom plate 110; the number of the first pins 520 is two, and the positions of the first pins 520 and the second pins 530 correspond to the positions of the first installation opening 210 and the second installation opening 220.

[0058] Please refer to Figure 6 and Figure 7, in one embodiment, mating surfaces 312a and step surfaces 312b are formed at both ends of the stator shaft 312. The mating surface 312a of the stator shaft abuts against the inner wall surface of the first sliding inlet 211 in a limiting manner, and the step surface 312b of the stator shaft abuts against the inner wall surfaces of the two side plates 120; and / or,

[0059] Mating surfaces 421 and step surfaces 422 are formed at both ends of the fixed shaft 420. The mating surface 421 of the fixed shaft abuts against the inner wall surface of the second sliding inlet 221 in a limiting manner, and the step surface 422 of the fixed shaft abuts against the inner wall surfaces of the two side plates 120.

[0060] Specifically, a mating surface 312a for abutting against the inner wall surface of the first sliding inlet 211 in a limiting manner is formed at the end of the stator shaft 312. The mating surface 312a is a flat surface. The mating surface 312a abuts against the side wall surfaces on both sides of the first sliding inlet 211 respectively to limit the stator shaft 312 in the transverse direction, and also abuts against the bottom wall of the first sliding inlet 211. The step surface 312b of the stator shaft abuts against the inner wall surfaces of the two side plates 120. With such a setting, the stator shaft 312 can be limited in the axial direction. At the same time, when connecting the stator shaft 312 and the mounting frame 100 with screws, it can also prevent the mounting frame 100 from deforming (that is, the two side plates 120 of the mounting frame 100 deform inward) when tightened too much, which may cause the teeth of the driving wheels 320 on multiple stator shafts 312 and the driving wheels 410 of the fixed shafts 420 not to be aligned correctly when meshing with each other, that is, the meshing gears are not in the same plane, and the "trapezoidal meshing" occurs during meshing, thus ensuring the service life of the driving wheels 320 and the driving wheels 410.

[0061] Similarly, a mating surface 421 for abutting against the inner wall surface of the second sliding inlet 221 in a limiting manner is formed at the end of the fixed shaft 420. The mating surface 421 is a flat surface. The mating surface 421 abuts against the side wall surfaces on both sides of the second sliding inlet 221 respectively to limit the fixed shaft 420 in the transverse direction, and also abuts against the bottom wall of the second sliding inlet 221. The step surface 422 of the fixed shaft abuts against the inner wall surfaces of the two side plates 120. With such a setting, the fixed shaft 420 can be limited in the axial direction. At the same time, when connecting the fixed shaft 420 and the mounting frame 100 with screws, it can also prevent the mounting frame 100 from deforming (that is, the two side plates 120 of the mounting frame 100 deform inward) when tightened too much, which may cause the teeth of the driving wheels 320 on multiple fixed shafts 420 and the driving wheels 410 of the fixed shafts 420 not to be aligned correctly when meshing with each other, that is, the meshing gears are not in the same plane, and the "trapezoidal meshing" occurs during meshing, thus ensuring the service life of the driving wheels 320 and the driving wheels 410.

[0062] Please refer toFigure 6 , in one embodiment, the first sliding inlet 211 includes a first extending inlet 211a and a first positioning port 211b that are in communication with each other. The first extending inlet 211a is used for the stator shaft 312 to be installed into the first positioning port 211b through it, and the width of the first extending inlet 211a is greater than the width of the first positioning port 211b; and / or,

[0063] The second sliding inlet 221 includes a second extending inlet 221a and a second positioning port 221b that are in communication with each other. The second extending inlet 221a is used for the fixed shaft 420 to be installed into the second positioning port 221b through it, and the width of the second extending inlet 221a is greater than the width of the second positioning port 221b.

[0064] Specifically, for the convenience of installing the driving device 300 from top to bottom into the first sliding inlet 211, the first sliding inlet 211 includes a first extending inlet 211a and a first positioning port 211b that are in communication with each other. When installing, the two ends of the stator shaft 312 of the driving device 300 are first installed into the first extending inlet 211a respectively, and then slide from the first extending inlet 211a into the first positioning port 211b for positioning. The stator shaft mating surface 312a is specifically in limiting abutment with the inner wall surface of the first positioning port 211b. Among them, the width of the first extending inlet 211a is greater than the width of the first positioning port 211b, which is convenient for the stator shaft 312 of the driving device 300 to be first installed into the first extending inlet 211a.

[0065] Similarly, for the convenience of installing the transmission device 400 from top to bottom into the second sliding inlet 221, the second sliding inlet 221 includes a second extending inlet 221a and a second positioning port 221b that are in communication with each other. When installing, the two ends of the fixed shaft 420 of the transmission device 400 are first installed into the second extending inlet 221a respectively, and then slide from the second extending inlet 221a into the second positioning port 221b for positioning. The fixed shaft mating surface 421 is specifically in limiting abutment with the inner wall surface of the second positioning port 221b. Among them, the width of the second extending inlet 221a is greater than the width of the second positioning port 221b, which is convenient for the fixed shaft 420 of the transmission device 400 to be first installed into the second extending inlet 221a.

[0066] Please refer to Figure 6 , in one embodiment, in the vertical direction, the height of the first extending inlet 211a is greater than the height of the first positioning port 211b, and / or, the height of the second extending inlet 221a is greater than the height of the second positioning port 221b.

[0067] With such a setting, it is convenient for both ends of the stator shaft 312 to extend into the first insertion opening 211a, and there is a certain moving space so that the end of the stator shaft 312 can move into the first positioning opening 211b for positioning. Also, it is convenient for both ends of the fixed shaft 420 to extend into the second insertion opening 221a, and there is a certain moving space so that the end of the fixed shaft 420 can move into the second positioning opening 221b for positioning.

[0068] Please refer to Figure 6 , in an embodiment, the distance between the two side walls of the first insertion opening 211a is greater than the diameter of the stator shaft 312, and / or the distance between the two side walls of the second insertion opening 221a is greater than the diameter of the fixed shaft 420.

[0069] Specifically, setting the distance between the two side walls of the first insertion opening 211a to be greater than the diameter of the stator shaft 312 allows the stator shaft 312 to pass through the first insertion opening 211a. When installing the stator shaft 312, one end of the stator shaft 312 can be passed through the first insertion opening 211a, then the other end can be moved downward into the first insertion opening 211a on the other side plate 120, and then the end of the stator shaft 312 is moved from the first insertion opening 211a to the first positioning opening 211b for positioning, which is convenient and fast. Similarly, setting the distance between the two side walls of the second insertion opening 221a to be greater than the diameter of the fixed shaft 420 allows the fixed shaft 420 to pass through the second insertion opening 221a. When installing the fixed shaft 420, one end of the fixed shaft 420 can be passed through the second insertion opening 221a, then the other end can be moved downward into the second insertion opening 221a on the other side plate 120, and then the end of the fixed shaft 420 is moved from the second insertion opening 221a to the second positioning opening 221b for positioning, which is convenient and fast.

[0070] Please refer to Figure 6 and Figure 7 , in an embodiment, first step surfaces 312c are further formed at both ends of the stator shaft 312. The distance from the first step surface 312c to the end face of the stator shaft 312 is greater than the distance from the stator shaft step surface 312b to the end face of the stator shaft 312. The first step surface 312c is used to limit the insertion depth of the first pin 520; and / or,

[0071] Second step surfaces 423 are further formed at both ends of the fixed shaft 420. The distance from the second step surface 423 to the end face of the fixed shaft 420 is greater than the distance from the fixed shaft step surface 422 to the end face of the fixed shaft 420. The second step surface 423 is used to limit the insertion depth of the second pin 530.

[0072] With such a setting, when the first pin 520 and the second pin 530 of the limit structure 500 are inserted into the first mounting opening 210 and the second mounting opening 220, the insertion depth can be deep enough to ensure the limiting effect of the limit structure 500 and prevent the first pin 520 and the second pin 530 from disengaging from the first mounting opening 210 or the second mounting opening 220.
