[0037] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.
[0038] The inventor of the present application has found that all the rollers in the existing roller machine are arranged evenly. When the roller machine is used to transport fruits and vegetables, foreign objects (leaves, branches) in the fruits and vegetables may fall from the gaps between the upper adjacent rollers to between the upper and lower rollers. If the foreign objects in the fruits and vegetables are retained between the upper and lower rollers and do not fall out from the gaps between the lower adjacent rollers, it may cause equipment failure or mold growth. The embodiments of the present application provide a roller machine, which is at least used to solve the above technical problems.
[0039] Please refer to Figure 1-Figure 4 The roller machine provided in the embodiment of the present application includes a support 1, a driving mechanism 2, a sprocket, a chain 3 and a plurality of roller groups 4, the driving mechanism 2 is arranged on the support 1, the driving mechanism 2 is connected to the sprocket, the chain 3 cooperates with the sprocket, each roller group 4 includes a first roller 41 and a second roller 42, the first roller 41 and the second roller 42 in each roller group 4 are connected to the chain 3, and the second roller 42 can swing around the axis of the first roller 41; when the roller group 4 is in the first working position, the connection direction of the first roller 41 and the second roller 42 in the roller group 4 is horizontal; when the roller group 4 is in the second working position, the connection direction of the first roller 41 and the second roller 42 in the roller group 4 is vertical.
[0040] In some embodiments, the roller machine also includes multiple third rollers 7, and the multiple third rollers 7 are all connected to the chain 3. The third rollers 7 are conventional rollers. The rollers are divided into a first roller 41, a second roller 42 and a third roller 7. The first roller 41 and the second roller 42 are only part of the rollers in the roller machine.
[0041] In some embodiments, the rollers only include a first roller 41 and a second roller 42 , and the first roller 41 and the second roller 42 form a roller group 4 .
[0042] It should be pointed out that the driving mechanism 2 includes a motor and a reduction gearbox, the motor and the reduction gearbox are drivingly connected, and the reduction gearbox and the sprocket are drivingly connected; when the roller group 4 is in the first working position, the roller group 4 is located above the roller machine, and the connection direction of the first roller 41 and the second roller 42 in the roller group 4 is horizontal. At this time, the first roller 41 and the second roller 42 can carry and transport fruits and vegetables; when the roller group 4 is in the second working position, the roller group 4 is located below the roller machine, and the connection direction of the first roller 41 and the second roller 42 in the roller group 4 is vertical. At this time, a gap is formed between the first rollers 41 in two adjacent roller groups 4 or between the first roller 41 and the third roller 7, and foreign objects in the fruits and vegetables can fall out through the gap.
[0043] During the operation of the roller machine, the motor drives the sprocket to rotate through the reduction box, and the sprocket drives the chain 3 to move, and multiple roller groups 4 move synchronously with the chain 3. When the roller group 4 moves to the first working position, the connection direction of the first roller 41 and the second roller 42 in the roller group 4 is horizontal. When the roller group 4 moves from the first working position to the second working position, the second roller 42 swings around the axis of the first roller 41 until the connection direction of the first roller 41 and the second roller 42 in the roller group 4 is vertical. At this time, the second roller 42 no longer hinders the falling of foreign objects, and foreign objects between the upper and lower rollers can fall out from the gap formed between the first rollers 41 in the two adjacent roller groups 4 or between the first roller 41 and the third roller 7, which is not easy to cause equipment failure or breed mold.
[0044] A plurality of pins are provided on the chain 3, and the first roller 41 in each roller group 4 is plugged into one of the pins, and the first roller 41 can rotate relative to the pin; each roller group 4 includes a connecting plate 43, and the connecting plate 43 is provided with a first connecting end 431 and a second connecting end 432, the first connecting end 431 is rotatably connected to the pin, and the second roller 42 is rotatably connected to the second connecting end 432.
[0045] The connecting plate 43 is strip-shaped, and the first connecting end 431 and the second connecting end 432 are the two ends of the connecting plate 43 respectively; the first connecting end 431 of the connecting plate 43 is rotatably connected to the pin shaft inserted into the first roller 41, and the second roller 42 is rotatably connected to the second connecting end 432 of the connecting plate 43.
[0046] The roller machine also includes a driving shaft 5 and a driven shaft 6, both of which are rotatably connected to the support 1, and the sprocket includes a driving sprocket 51 and a driven sprocket 61. The driving mechanism 2 is connected to the driving shaft 5 to drive the driving shaft 5 to rotate; the driving sprocket 51 is coaxially connected to the driving shaft 5, the driven sprocket 61 is coaxially connected to the driven shaft 6, and the chain 3 cooperates with the driving sprocket 51 and the driven sprocket 61 at the same time; a transition wheel 62 is coaxially arranged on the driven shaft 6, and when the roller group 4 moves from the second working position to the first working position, the transition wheel 62 abuts against the first roller 41 and the second roller 42 in turn to guide the first roller 41 and the second roller 42.
[0047] The motor is connected to the reduction gearbox, which is connected to the driving shaft 5. The motor drives the driving shaft 5 and the driving sprocket 51 to rotate through the reduction gearbox, thereby driving the chain 3 and the driven sprocket 61 to rotate. The roller group 4 and the third roller 7 move synchronously with the chain 3.
[0048] The transition wheel 62 can rotate relative to the driven shaft 6. When the roller group 4 moves from the second working position to the first working position, the first roller 41 and the second roller 42 in the roller group 4 abut against the transition wheel 62 in turn. The transition wheel 62 guides the first roller 41 and the second roller 42, so that the roller group 4 can stably transition to the first working position.
[0049] In some embodiments, a guide plate 11 is provided on the support 1 near the driving shaft 5 , and the guide plate 11 is provided with a downwardly inclined guide slope 111 ; when the roller group 4 moves from the first working position to the second working position, the second roller 42 is used to abut against the guide slope 111 .
[0050] The guide slope 111 on the guide plate 11 extends toward the inner side of the roller machine. When the roller group 4 moves from the first working position to the second working position, the second roller 42 swings downward around the axis of the first roller 41 and abuts against the guide slope 111 until the second roller 42 disengages from the guide slope 111. The guide slope 111 guides the second roller 42, so that the roller group 4 stably transitions to the second working position.
[0051] In some embodiments, a supporting member 12 for supporting the first roller 41 and the second roller 42 is disposed on the support 1 . When the roller group 4 is in the first working position, the supporting member 12 supports the first roller 41 and the second roller 42 .
[0052] When the roller group 4 moves from the second working position to the first working position, the supporting member 12 supports the first roller 41 and the second roller 42, so that the connecting direction of the first roller 41 and the second roller 42 in each roller group 4 is horizontal, so as to carry out normal fruit and vegetable transportation.
[0053] In some embodiments, the supporting member 12 is in an elongated strip shape, and the supporting member 12 extends along the length direction of the chain 3 .
[0054] When the roller group 4 moves from the second working position to the first working position, the long strip-shaped supporting member 12 can always support the first roller 41 and the second roller 42, preventing the second roller 42 from swinging downward around the axis of the first roller 41, so that the connecting direction of the first roller 41 and the second roller 42 in each roller group 4 is always horizontal.
[0055] In some embodiments, each roller group 4 includes a first roller 41 and multiple second rollers 42, the first roller 41 and the second roller 42 in each roller group 4 are connected to the chain 3, and the multiple second rollers 42 can swing around the axis of the first roller 41; when the roller group 4 is in the first working position, the connecting direction of the first roller 41 and the multiple second rollers 42 in the roller group 4 is horizontal; when the roller group 4 is in the second working position, the connecting direction of the first roller 41 and the multiple second rollers 42 in the roller group 4 is vertical.
[0056] The first roller 41 in each roller group 4 is plugged into one of the pins, and the first roller 41 can rotate relative to the pin; the first connecting end 431 of the connecting plate 43 is rotatably connected to the pin to which the first roller 41 is plugged, one of the second rollers 42 is rotatably connected to the second connecting end 432 of the connecting plate 43, and the remaining second rollers 42 are rotatably connected to the middle part of the connecting plate 43, so that the first roller 41 and multiple second rollers 42 are located on the same straight line.
[0057] When the roller group 4 moves from the first working position to the second working position, the multiple second rollers 42 swing around the axis of the first roller 41 at the same time until the connecting direction of the first roller 41 and the multiple second rollers 42 in the roller group 4 is in the vertical direction. At this time, the multiple second rollers 42 no longer hinder the falling of foreign objects. The gaps created by the multiple second rollers 42 swinging downward are larger, and foreign objects between the upper and lower rollers are more likely to fall out of the gaps, thereby reducing equipment failures or mold growth.
[0058] In some embodiments, the roller machine further includes a driving member connected to the first connecting end 431 to drive the connecting plate 43 to rotate around the axis of the pin shaft.
[0059] The driving member includes a motor, which is connected to the first connecting end 431. When the roller group 4 moves from the first working position to the second working position, the driving member drives the connecting plate 43 to rotate around the axis of the pin shaft so that the connection direction of the first roller 41 and the second roller 42 in the roller group 4 is in the vertical direction. When the roller group 4 moves from the second working position to the first working position, the driving member drives the connecting plate 43 to rotate around the axis of the pin shaft so that the connection direction of the first roller 41 and the second roller 42 in the roller group 4 is in the horizontal direction, thereby facilitating automatic adjustment of the working state of the roller group 4.
[0060] In order to monitor the working position of the roller group 4 and automatically adjust the working state of the roller group 4, the roller machine also includes a controller and a sensor. The controller is electrically connected to the driving member and the sensor at the same time. The sensor is used to detect the position of the roller group 4; when the sensor detects that the roller group 4 is in the first working position, the controller controls the driving member to operate so that the connection direction of the first roller 41 and the second roller 42 in the roller group 4 is in the horizontal direction; when the sensor detects that the roller group 4 is in the second working position, the controller controls the driving member to operate so that the connection direction of the first roller 41 and the second roller 42 in the roller group 4 is in the vertical direction.
[0061] When the sensor detects that the roller group 4 is in the first working position, the controller controls the driving member to operate so that the connection direction of the first roller 41 and the second roller 42 in the roller group 4 is horizontal. At this time, the first roller 41 and the second roller 42 can carry and transport fruits and vegetables; when the sensor detects that the roller group 4 is in the second working position, the controller controls the driving member to operate so that the connection direction of the first roller 41 and the second roller 42 in the roller group 4 is vertical. At this time, a gap is formed between the first rollers 41 in two adjacent roller groups 4 or between the first roller 41 and the third roller 7, and foreign objects in the fruits and vegetables can fall out through the gap.
[0062] The sensor may be a position sensor, a displacement sensor, a positioning sensor, etc., as long as it can detect the position of the roller group 4, and there is no limitation on this.
[0063] An embodiment of the present application further provides a fruit and vegetable production line, comprising the above-mentioned drum machine.
[0064] In summary, the embodiment of the present application provides a drum machine and a fruit and vegetable production line. During the operation of the drum machine, the driving mechanism 2 drives the sprocket to rotate, the sprocket drives the chain 3 to move, and the multiple roller groups 4 move synchronously with the chain 3. When the roller group 4 moves to the first working position, the connection direction of the first roller 41 and the second roller 42 in the roller group 4 is horizontal. When the roller group 4 moves from the first working position to the second working position, the second roller 42 swings around the axis of the first roller 41 until the connection direction of the first roller 41 and the second roller 42 in the roller group 4 is vertical. At this time, the second roller 42 no longer hinders the falling of foreign objects, and foreign objects between the upper and lower rollers can fall out from the gap formed between the first rollers 41 in the two adjacent roller groups 4 or between the first roller 41 and the third roller 7, which is not easy to cause equipment failure or mold growth.
