The driving wheel includes a first transmission wheel and a second transmission wheel spaced apart along the axial direction of the transmission shaft 110. The second transmission wheel is rotationally connected to the transmission shaft 110 via a clutch mechanism. The first transmission component is in transmission connection with the first transmission wheel and the driven wheel 500. The second transmission component is in transmission connection with the second transmission wheel and the driven wheel 500. Both the first transmission component and the second transmission component are capable of conveying in a first direction.

A carton accommodating space 230 is formed between the first blocking component 210 and the second blocking component 220.

[0026] The carton conveying device drives the first transmission component and the second transmission component to move to convey cartons through the driving wheel and the driven wheel 500. When the cartons need to be transported, the clutch mechanism is controlled to connect the second transmission wheel to the transmission shaft 110, and the transmission shaft 110 rotates. At this time, the second transmission wheel can rotate with the transmission shaft 110, and the transmission shaft 110 simultaneously drives the first transmission wheel and the second transmission wheel to rotate, so that the first transmission component and the second transmission component are synchronously conveyed along the first direction. The first transmission component can drive the first barrier component 210 to move, and the second transmission component can drive the second barrier component 220 to move, thereby realizing the synchronous movement of the first barrier component 210 and the second barrier component 220 along the first direction. At this time, the distance between the first barrier component 210 and the second barrier component 220 is constant, that is, the carton accommodating space 230 formed between the first barrier component 210 and the second barrier component 220 is constant, and the first barrier component and the second barrier component 220 drive the carton accommodating The cartons in the space 230 are transported, and the first barrier component 210 and the second barrier component 220 can position the cartons in transport, and the first barrier component 210 and the second barrier component 220 play a protective role on the cartons to prevent the cartons from being deformed during transportation and from being displaced during transportation, so that the cartons can be accurately transported to other processes and accurately positioned at the designated positions of other processes, thereby ensuring stable forming and transportation of the cartons. When it is necessary to adapt to cartons of different sizes, the clutch mechanism is released to separate the second transmission wheel from the transmission shaft 110, and then the operator rotates the second transmission wheel to drive the second barrier component 220 to move and adjust the distance between the first barrier component 210 and the second barrier component 220, that is, to achieve adjustable carton accommodating space 230 formed between the first barrier component 210 and the second barrier component 220. The carton conveying device can be suitable for cartons of more sizes.

Specifically, the first connecting member 212 is connected to the side of the first link 121 through a chain buckle, and the second connecting member 222 is connected to the side of the second link 131 through a chain buckle, so as to avoid affecting the transmission connection between the first chain 120 and the first sprocket 150 and the transmission connection between the second chain 130 and the second sprocket 140.

[0031] It can be understood that in some other embodiments, when the first transmission component and the second transmission component are both belts, the first partition 211 is connected to the belt through the first connecting member 212, and the second partition 221 is connected to the belt through the second connecting member 222, and the first connecting member 212 and the second connecting member 222 can be fixedly connected to one side of the belt by a buckle.

[0032] Reference Figures 1 to 5In some embodiments, an installation space is formed between the first chain 120 and the second chain 130, and the first connecting member 212 and the second connecting member 222 are both located in the installation space, the first connecting member 212 is connected to the bottom of the first partition 211, and the second connecting member 222 is connected to the bottom of the second partition 221. This arrangement allows the first connecting member 212 and the second connecting member 222 to be alternately arranged along the first direction, the first connecting member 212 is connected to the middle position of the bottom of the first partition 211, and the second connecting member 222 is connected to the middle position of the bottom of the second partition 221, which strongly supports the first partition 211 and the second partition 221, so that when the device is running, it can strongly push the cardboard to avoid carton displacement during carton transportation.

[0034] Reference Figures 1 to 5 In some embodiments, the clutch mechanism includes a sleeve 160 and a pressure ring 170. The sleeve 160 is disposed on the transmission shaft 110 and has a protrusion. The inner ring of the pressure ring 170 engages the protrusion. The outer ring of the pressure ring 170 is detachably connected to the second sprocket 140. Specifically, the pressure ring 170 and the second sprocket 140 are connected by screws or pins. It is understood that the clutch mechanism may also include a friction sleeve that limits the rotation of the second sprocket 140 about the transmission shaft 110. When adjusting the carton storage space 230, the operator slightly loosens the screws between the pressure ring 170 and the second sprocket 140. The outer circumference of the pressure ring 170 has a hole for inserting a handle. The operator can bend the pressure ring 170 to rotate it, thereby driving the sprocket 150 to rotate. At this time, the sprocket 140 does not move, thereby changing the spacing 230.

The first spacer 180 is a step spacer. The large outer cylindrical end surface of the step spacer abuts the side surface of the first sprocket 150, and the small outer cylindrical end surface of the step spacer abuts the side surface of the sleeve. Specifically, a margin is left between the first bearing 181 and the step spacer, so that the first bearing 181 can move along the axial direction of the transmission shaft 110, thereby facilitating the adjustment of the spacing between the first sprocket 150 and the second sprocket 140.
