For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0022] See Figure 1 And 2 As shown in the drawings, the chain clamping and conveying packaging box device according to the embodiments of the present application comprises a horizontal chain conveying belt 1, a feeding roller 2 and a discharging roller 3.

[0023] The chain conveying belt 1 comprises a plurality of chain belts and a driving sprocket 11 and a driven sprocket 12 engaging and driving the chain belts. The driving sprocket 11 and the driven sprocket 12 have the same diameter. The driving sprocket 11 is arranged on a driving shaft 13 driven by a motor. The driven sprocket 12 is arranged on a driven shaft 14. The chain is connected by a plurality of chain links 15 through connecting pins 16.

[0024] The working surface of the discharging roller 3 carrying the packaging box is slightly lower than or flush with the working surface of the chain conveying belt 1 carrying the packaging box.

[0025] The working surface of the feeding roller 2 carrying the packaging box is flush with the working surface of the chain conveying belt 1 carrying the packaging box.

[0026] The above structure is a common chain conveying structure in the industry. The innovation of the present application lies in that the chain clamping and conveying packaging box device further comprises an even number of clamping plate assemblies 4.

[0027] The clamping plate assembly 4 comprises a connecting rod 41, a mounting plate 42 and a clamping plate 43.

[0028] The clamping plate 43 has a working surface 431 for clamping the packaging box, and the upper edge of the working surface 431 is provided with a circular arc chamfer. The clamping plate 43 is installed on the mounting plate 42 through a spring mechanism, and has a tendency to move away from the mounting plate. Specifically, the clamping plate 43 is provided with a guide column 432 on the side opposite to the working surface 431, and the mounting plate 42 is provided with a hole for slidably sleeving the guide column 432, and the outer end of the guide column 432 extends out of the hole of the mounting plate 42 and is provided with a stop portion for abutting against the mounting plate 42. The spring mechanism includes a spring 44 arranged between the clamping plate 43 and the mounting plate 42, and in the preferred embodiment, the spring 44 is sleeved on the guide column 432.

[0029] One end of the connecting rod 41 is hinged to the mounting plate 42, and the other end of the connecting rod 41 is rotatably arranged on one connecting pin 16, and the mounting plate 42 is also rotatably arranged on another connecting pin 16. There are also a plurality of chain links 15 between the two connecting pins 16.

[0030] The length between the hinging point of the connecting rod 41 and the connecting pin 16 and the hinging point of the connecting rod 41 and the mounting plate 42, the length between the hinging point of the mounting plate 42 and the connecting rod 41 and the hinging point of the mounting plate 42 and the connecting pin 16, the length of the chain link 15 between the two connecting pins 16, and the diameters of the driving sprocket 11 and the driven sprocket 12 form a specific matching relationship: the chain moves along the path constrained by the driving sprocket 11 and the driven sprocket 12, and when the connecting pin 16 moves to the driving sprocket 11 / driven sprocket 12, the linear distance between the two connecting pins 16 changes, but the working surface 431 of the clamping plate 43 is always in a vertical state and always parallel to the axis of the sprocket.

[0031] In the length direction of the chain, every two adjacent clamping plate assemblies 4 are arranged in mirror symmetry, and the working surfaces of the two clamping plates face each other and can form a space for clamping the packaging box, and such two adjacent clamping plate assemblies 4 form a pair of clamping plate assembly pairs. A plurality of pairs of clamping plate assembly pairs are arranged on the chain, and the clamping plate assembly pairs are uniformly arranged in the length direction of the chain.

[0032] When the clamping plate 43 moves to the two ends of the conveying belt, the top end of the working surface 431 is not higher than the working surface of the conveying belt for carrying the packaging box.

[0033] It should be noted that the embodiment Figure 1 and Figure 2 is only illustrative, and in the drawings, only the states of the clamping plate assembly pairs in the horizontal position and in the sprocket position are embodied, and the length of the chain is shortened and the diameter of the sprocket is reduced, which is to more clearly show the structural features of the present application.

[0034] In combination with the above device structure, the working principle thereof is described as follows:

[0035] 1. When the packaging box on the feeding roller 2 moves forward and approaches the discharge position, the clamping plate 43 of the clamping plate assembly in the front of the clamping plate assembly pair rises vertically with the movement of the chain, and moves forward in the horizontal direction.

[0036] 2. Since the feeding roller 2 and the chain conveyor are synchronized, the chain transmission speed has a component in the vertical direction, so the forward speed of the packaging box on the feeding roller 2 is higher than the forward speed of the clamping plate 43, the front side of the packaging box begins to abut against the working surface 431 of the clamping plate 43, and with the pushing of the feeding roller 2, the front side is completely attached to the working surface 431, the adjustment of the angle of the packaging box is realized, and the packaging box begins to be carried by the chain.

[0037] 3. Then the clamping plate 43 of the clamping plate assembly in the rear of the clamping plate assembly pair also rises vertically with the movement of the chain, and the arc chamfer on the working surface 431 abuts against the rear edge of the bottom surface of the packaging box, and is retracted on the mounting plate under the force of the arc chamfer, and with the rising of the clamping plate 43, the clamping plate assembly clamps the packaging box.

[0038] During the rising (falling) of one clamping plate 43 in the clamping plate assembly pair, the spacing between the two mounting plates 42 in the clamping plate assembly pair changes, and the retraction of the clamping plate 43 ensures that the spacing between the two mounting plates always maintains the spacing of the packaging box.

[0039] 4. When the clamping plate 43 of the clamping plate assembly in the front of the clamping plate assembly pair moves to the chain wheel position in front of the conveyor, the clamping plate 43 begins to fall until it is below the working surface of the chain conveyor carrying the packaging box to leave a channel for the packaging box to move forward, and the clamping plate 43 of the clamping plate assembly in the rear of the clamping plate assembly pair continues to push the packaging box until it pushes the packaging box to the discharge roller 3.

[0040] The above embodiments are used to describe the application intent and implementation of the present application, but those skilled in the art can understand that the above embodiments of the present application are only one of the preferred embodiments of the present application, and due to the limitation of the length, all the embodiments cannot be listed one by one, any embodiment that can embody the technical solution of the claims of the present application is within the protection scope of the present application.

[0041] It should be noted that the above is a further detailed description of the present application in combination with specific embodiments, and the specific embodiments of the present application cannot be limited to the above, and those skilled in the art can make various improvements and modifications on the basis of the above embodiments, and these improvements or modifications fall within the protection scope of the present application.
