[0029] The following further describes the present utility model in detail with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only parts related to the present utility model are shown in the drawings, rather than all the structures.

[0030] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath", and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0032] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0033] During the latter stage of the packaging and conveying process of carton or film-wrapped products, the conveying direction of the products often needs to be changed, converting the long side of the product into the short side or the short side into the long side, so as to meet the requirements of the latter-stage stacking or reduce the overall length of the conveyor belt. For this purpose, a steering device and a production line are provided in this embodiment. This device can be applied during the conveying process of the products to provide power for the steering of the products, and the manufacturing cost of this steering device is reduced compared with other steering devices, thereby reducing the manufacturing and maintenance costs of the entire production line.

[0034] Please refer to Figures 1 to 4As shown in the figure, the steering device includes a frame 1, a rotating mechanism 2, and a clamping mechanism 3. The rotating mechanism 2 is arranged on the frame 1; the clamping mechanism 3 includes a mounting seat 31 connected to the rotating mechanism 2, a clamping driving member 32 arranged on the mounting seat 31, a transmission assembly 33 drivingly connected to the clamping driving member 32, and two relatively and spaced clamping assemblies 34. The rotating mechanism 2 can drive the mounting seat 31 to rotate. The clamping assembly 34 includes a connecting rod group 341 and a clamping member 342. The connecting rod group 341 includes two first connecting rods 3411 and second connecting rods 3412 that are parallel and spaced apart. The clamping member 342 is rotatably connected to both the first connecting rod 3411 and the second connecting rod 3412. Both the first connecting rod 3411 and the second connecting rod 3412 are rotatably connected to the mounting seat 31. The transmission assembly 33 is drivingly connected to both first connecting rods 3411 at the same time, and the transmission assembly 33 can drive the two first connecting rods 3411 to rotate in opposite directions at the same time. The two clamping members 342 can jointly clamp an object 100.

[0035] Specifically, in this embodiment, both the first connecting rod 3411 and the second connecting rod 3412 in the two clamping assemblies 34 are rotatably connected to the mounting seat 31. The clamping member 342 in the two clamping assemblies 34 is rotatably connected to the first connecting rod 3411. A clamping driving member 32 is also arranged on the mounting seat 31. The clamping driving member 32 is drivingly connected to the two first connecting rods 3411 through the transmission assembly 33. Then, by driving of one clamping driving member 32, the two first connecting rods 3411 are driven to rotate in opposite directions. Thus, the first connecting rod 3411 drives the clamping member 342 to rotate, and the rotation directions of the two clamping members 342 are opposite. When one clamping member 342 rotates clockwise, the other clamping member 342 rotates counterclockwise. With such an arrangement, the two clamping members 342 can clamp or release the object 100 through one clamping driving member 32. Moreover, the connecting rod group 341 and the clamping member 342 form a four-bar mechanism with the mounting seat 31. When the clamping driving member 32 drives the two clamping members 342 to approach the object 100, the two clamping members 342 also move downward in the vertical direction. When the clamping driving member 32 drives the two clamping members 342 to move away from the object 100, the two clamping members 342 also move upward in the vertical direction. With such an arrangement, the two clamping members descend while performing the clamping action and ascend while performing the releasing action. After the clamping assembly 34 clamps the object 100, the rotating mechanism 2 connected to the mounting seat 31 rotates and drives the clamping mechanism 3 to rotate, thereby driving the object 100 to complete the steering. In this embodiment, the clamping driving member 32 is specifically a motor, and the rotating mechanism 2 relies on the motor for rotational driving.

[0036] Optionally, as Figures 3 to 4As shown in the figure, the transmission assembly 33 includes a driving wheel 331, a transition wheel 332 and two driven wheels 333. The clamping driving member 32 is in transmission connection with the driving wheel 331 and is used to drive the driving wheel 331 to rotate. The two driven wheels 333 are respectively arranged on the rotating shafts 34111 of the two first connecting rods 3411. The rotating shafts 34111 are rotatably connected to the mounting seat 31. The transition wheel 332 is rotatably connected to the mounting seat 31. The driving wheel 331 meshes with one of the driven wheels 333 and also meshes with the transition wheel 332. The transition wheel 332 meshes with the other driven wheel 333. Specifically, in this embodiment, the driving wheel 331 directly meshes with the transition wheel 332 and one of the driven wheels 333 at the same time, and the other driven wheel 333 directly meshes with the transition wheel 332. Therefore, when the clamping driving member 32 drives the driving wheel 331 to rotate, the rotation directions of the two driven wheels 333 are exactly opposite. One of the driven wheels 333 that directly meshes with the driving wheel 331 rotates in the opposite direction to the driving wheel 331, and the other driven wheel 333 that meshes with the transition wheel 332 rotates in the same direction as the driving wheel 331. In this way, the rotation directions of the two first connecting rods 3411 can be opposite, and then the two clamping members 342 can be driven to rotate in opposite directions. The size of the distance between the two clamping members 342 is determined by the diameters and tooth numbers of the driving wheel 331, the transition wheel 332 and the two driven wheels 333. In other embodiments, the two driven wheels 333 can be respectively in transmission connection with the two second connecting rods 3412, and the two clamping members 342 can be driven to rotate in opposite directions at the same time through the two second connecting rods 3412.

[0037] Further, as Figure 3 shown, the tooth number of the transition wheel 332 is equal to that of the driven wheel 333. With such a setting, it is ensured that the rotation speeds of the two driven wheels 333 are the same, and the clamping and loosening of the object 100 by the two clamping members 342 are synchronous, so that the object 100 can be kept stable when being clamped and loosened, which is more conducive to the clamping assembly 34 to clamp the object 100.

[0038] Further, as Figure 3 shown, the tooth number of the driving wheel 331 is greater than that of the driven wheel 333. With such a setting, the torque of the two driven wheels 333 is increased, and indirectly the clamping force of the two clamping members 342 is increased, making the clamping of the object 100 more reliable.

[0039] Optionally, as Figures 3 to 4As shown, the clamping assembly 34 further includes an anti-slip pad 343. The anti-slip pad 343 is disposed on the clamping member 342 and is used to contact the object 100. The anti-slip pad 343 is provided for two purposes. One is to increase the contact area between the clamping member 342 and the object 100, and the other is to increase the friction coefficient between the clamping member 342 and the object 100. Thus, the clamping of the clamping member 342 on the object 100 is made more reliable through the anti-slip pad 343. Moreover, since the material hardness of the anti-slip pad 343 is relatively low, damage to the object 100 can also be reduced.

[0040] Optionally, as Figures 3 to 4 shown, the clamping assembly 34 includes two link groups 341 and two clamping members 342, and the two link groups 341 and the two clamping members 342 are both arranged at intervals. In this embodiment, there are two link groups 341 and two clamping members 342 in the clamping assembly 34. The two first links 3411 in the clamping assembly 34 are connected by a rotating shaft 34111. The two first links 3411 drive the two clamping members 342 to rotate respectively. The two clamping members 342 arranged at intervals in one clamping assembly 34 can increase the clamping range and improve the practicability of the clamping mechanism 3. It should be noted that in this embodiment, there are two link groups 341 and two clamping members 342 in the clamping assembly 34. In other embodiments, the number of the link group 341 and the clamping member 342 in the clamping assembly 34 can be determined according to the actual situation, and the number is not limited herein.

[0041] Further, as Figures 3 to 4 shown, the clamping assembly 34 further includes a first connecting shaft 344. The first connecting shaft 344 is respectively connected to the two clamping members 342. The first connecting shaft 344 is used to increase the stiffness of the entire clamping assembly 34.

[0042] Further, as Figures 3 to 4 shown, the first connecting shaft 344 is respectively rotatably connected to the two clamping members 342, and the two first links 3411 are both fixedly connected to the first connecting shaft 344. With such an arrangement, the two first links 3411 are rotatably connected to the two clamping members 342 through the first connecting shaft 344. The first connecting shaft 344 can also ensure the synchronism of the rotational movements of the two clamping members 342. In this embodiment, the specific connection form between the first connecting shaft 344 and the two clamping members 342 is a hinge connection.

[0043] Further, as Figures 3 to 4 shown, the clamping assembly 34 further includes a second connecting shaft 345. The second connecting shaft 345 is rotatably connected to the mounting base 31, and the two second links 3412 are both fixedly connected to the second connecting shaft 345. With such an arrangement, the two second links 3412 are connected by the second connecting shaft 345 to ensure that the two second links 3412 can rotate synchronously, and the stiffness of the entire clamping assembly 34 can also be increased.

[0044] Further, as Figure 1 and Figure 2 shown, the steering device further includes a conveyor line 200. The frame 1 is provided with a channel. The conveyor line 200 passes through the channel and is located below the clamping mechanism 3. The conveyor line 200 is used to convey an object 100. In this embodiment, a frame 1 is arranged outside the conveyor line 200 for conveying the object 100. The frame 1 is provided with a channel. The conveyor line 200 passes through the channel and continuously conveys the object 100. The conveyor line 200 is specifically a belt conveyor. The rotating mechanism 2 and the clamping mechanism 3 are installed on the frame 1. When the conveyor line 200 moves the object 100 to directly below the clamping mechanism 3, the clamping mechanism 3 operates to clamp the object 100. Then, the rotating mechanism 2 operates to drive the clamping mechanism 3 to turn in the conveying plane. In this embodiment, it rotates 90 degrees. After the rotation is in place, the clamping mechanism 3 operates in the reverse direction to release the object 100, and the rotating mechanism 2 operates in the reverse direction to turn the clamping mechanism 3 back to its original position. The conveyor line 200 feeds the turned object 100 into the next process. By repeating the above operations, several objects 100 that need to be turned on the conveyor line 200 are turned in sequence.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
