[0027] The driving component is used to drive the first belt 201 and the second belt 202 to move away from or close to each other;

[0028] The transmission component is used to drive the second belt 202 to operate, and the second belt 202 in the operating state is used to drive the first belt 201 to operate synchronously through the connecting rod component.

[0029] Please refer specifically to Figure 2 , the driving component includes a shaft-holding motor 301, a bidirectional lead screw 302, a guide rod 307, two moving frames 303 and a baffle 304;

[0030] The shaft-holding motor 301 is installed on the outside of the frame 1, the bidirectional lead screw 302 is rotatably connected to one end inside the frame 1, and the bidirectional lead screw 302 is connected to the end of the output shaft of the shaft-holding motor 301. One end of the moving frame 303 is connected to the bidirectional lead screw 302 through a lead screw seat. The baffle 304 is fixedly connected to the top of the moving frame 303. The guide rod 307 is fixedly connected to the other end inside the frame 1, and the other end of the moving frame 303 is slidably connected to the outer wall of the guide rod 307.

[0031] In this embodiment: By energizing and operating the shaft-holding motor 301, the output shaft of the shaft-holding motor 301 in the operating state drives the bidirectional lead screw 302 to rotate. Since one moving frame 303 engages with the positive thread of the bidirectional lead screw 302 and the other moving frame 303 engages with the reverse thread of the bidirectional lead screw 302, the rotating bidirectional lead screw 302 drives the two moving frames 303 to move synchronously and close to each other along the trajectory of the guide rod 307. The two moving frames 303 in the state of moving close to each other respectively drive the two groups of driving rollers 308, the first belt 201 and the second belt 202 to move close to each other.

[0032] Please refer specifically to Figure 2 , the inner cavity of one end of one moving frame 303 is provided with an internal thread that engages with the positive thread of the bidirectional lead screw 302, and the inner cavity of one end of the other moving frame 303 is provided with an internal thread that engages with the reverse thread of the bidirectional lead screw 302.

[0033] In this embodiment: Since one moving frame 303 engages with the positive thread of the bidirectional lead screw 302 and the other moving frame 303 engages with the reverse thread of the bidirectional lead screw 302, the rotating bidirectional lead screw 302 drives the two moving frames 303 to move synchronously and close to each other along the trajectory of the guide rod 307.

[0034] Please refer specifically to Figure 3The transmission assembly includes a through slot 305, a servo motor 306, a first synchronous wheel 309, a second synchronous wheel 3010, a synchronous belt 3011 and two sets of driving rollers 308;

[0035] The through groove 305 is opened on the outer side of the frame 1 and completely penetrates through it. The driving roller 308 is rotatably connected to the inner side of the movable frame 303, and the driving roller 308 has a hollow structure. The servo motor 306 is installed at the end of one driving roller 308. The first synchronous wheel 309 is assembled on the outer wall of the protruding part of one driving roller 308, and the second synchronous wheel 3010 is assembled on the outer wall of the protruding part of the other driving roller 308. The first synchronous wheel 309 and the second synchronous wheel 3010 are connected by a synchronous belt 3011, and the outer sides of the first synchronous wheel 309 and the second synchronous wheel 3010 are meshed with the teeth on the inner side of the synchronous belt 3011.

[0036] In this embodiment: by connecting the servo motor 306 to electricity and running, the output shaft of the servo motor 306 in the running state drives a driving roller 308 to rotate, and the driving roller 308 in the rotating state drives the first synchronous wheel 309 to rotate. Since the rotation of the first synchronous wheel 309 is meshed with the outer side of the second synchronous wheel 3010 and the tooth groove on the inner side of the synchronous belt 3011, the first synchronous wheel 309 in the rotating state drives the second synchronous wheel 3010 to rotate synchronously through the synchronous belt 3011, and the second synchronous wheel 3010 in the rotating state drives another driving roller 308 to rotate, then a group of driving rollers 308 in the rotating state drives the second belt 202 to run, and at the same time, a group of driving rollers 308 in the rotating state drives another group of driving rollers 308 to rotate synchronously through the connecting rod 3012, and the other group of driving rollers 308 in the rotating state drives the first belt 201 to run, so that the first belt 201 and the second belt 202 achieve the effect of synchronous operation.

[0037] Please refer to Figure 4 , the connecting rod assembly includes a connecting rod 3012 and a spring 3013;

[0038] The connecting rod 3012 is slidably connected to the inner cavity of the driving roller 308 and extends to the outside thereof. The spring 3013 is installed in the inner cavity of the driving roller 308, and the end of the spring 3013 is fixedly connected to the connecting rod 3012.

[0039] In this embodiment: the connecting rod 3012 is moved inwardly by two sets of driving rollers 308 in a state of being close to each other, and the connecting rod 3012 moving inwardly of the driving rollers 308 squeezes the spring 3013, so that the spring 3013 is compressed, and thus the distance between the first belt 201 and the second belt 202 in a state of being close to each other will be smaller.

[0040] Please refer to Figure 3, the second belt 202 is disposed on the outer wall of a set of drive rollers 308, the first belt 201 is disposed on the outer wall of another set of drive rollers 308, and a set of drive rollers 308 in a synchronous rotation state is used to drive another set of drive rollers 308 to rotate synchronously through a connecting rod 3012.

[0041] In this embodiment: a set of drive rollers 308 in a rotating state drives the second belt 202 to run, and at the same time, a set of drive rollers 308 in a rotating state drives another set of drive rollers 308 to rotate synchronously through a connecting rod 3012, and another set of drive rollers 308 in a rotating state drives the first belt 201 to run.

[0042] Please refer specifically to Figure 3 , a plurality of auxiliary rollers 4 are rotatably installed inside the frame 1, and the plurality of auxiliary rollers 4 are all disposed at the inner rings of the first belt 201 and the second belt 202, and through holes for the protruding parts of the auxiliary rollers 4 to penetrate are formed on the surface of the moving frame 303.

[0043] In this embodiment: since a plurality of auxiliary rollers 4 are rotatably installed inside the frame 1, the plurality of active auxiliary rollers 4 assist in moving the articles.

[0044] Working principle: When it is necessary to adjust the distance between the first belt 201 and the second belt 202, first, the shaft-holding motor 301 is powered on and operated, so that the output shaft of the shaft-holding motor 301 in the operating state drives the bidirectional lead screw 302 to rotate. Since one moving frame 303 engages with the positive thread of the bidirectional lead screw 302, and the other moving frame 303 engages with the reverse thread of the bidirectional lead screw 302, the rotating bidirectional lead screw 302 drives the two moving frames 303 to move synchronously and approach each other along the trajectory of the guide rod 307. The two moving frames 303 in the approaching movement state respectively drive the two sets of drive rollers 308, the first belt 201 and the second belt 202 to move closer to each other. Then, the two sets of drive rollers 308 in the approaching movement state cause the connecting rod 3012 to move into it. The connecting rod 3012 moving into the drive roller 308 squeezes the spring 3013, so that the spring 3013 is compressed by the force. Furthermore, the distance between the first belt 201 and the second belt 202 in the approaching movement state will be reduced, which is suitable for transporting articles with a smaller volume. As described above, the distance between the first belt 201 and the second belt 202 in the moving-away state will increase, which is suitable for transporting articles with a larger volume, thus facilitating the adjustment of the distance between the first belt 201 and the second belt 202;

[0045] When the distance between the first belt 201 and the second belt 202 is adjusted, the servo motor 306 is powered on and operates at this time. The output shaft of the servo motor 306 in the operating state drives a driving roller 308 to rotate. The rotating driving roller 308 drives the first synchronous pulley 309 to rotate. Since the outer side of the first synchronous pulley 309 rotates and meshes with the tooth grooves on the inner side of the second synchronous pulley 3010, the rotating first synchronous pulley 309 drives the second synchronous pulley 3010 to rotate synchronously through the synchronous belt 3011. The rotating second synchronous pulley 3010 drives another driving roller 308 to rotate. Then, a set of rotating driving rollers 308 drives the second belt 202 to operate. At the same time, a set of rotating driving rollers 308 drives another set of driving rollers 308 to rotate synchronously through the connecting rod 3012. The rotating another set of driving rollers 308 drives the first belt 201 to operate. Thus, the first belt 201 and the second belt 202 achieve the effect of synchronous operation. At this time, the items to be transported are placed on the first belt 201 and the second belt 202. The operating first belt 201 and the second belt 202 transport the items to the designated area. And because a plurality of auxiliary rollers 4 are rotatably installed inside the frame 1, the plurality of movable auxiliary rollers 4 assist the items to move.

The scope of the present invention is defined by the appended claims and their equivalents.
