Description

Technical Field

[0001] This utility model mainly relates to the field of label production technology, specifically to a shaft-mounted clamping mechanism. Background Technology

[0002] During the label production process, the label needs to be transported by the conveyor rollers through multiple processes such as coding, curing, inspection, and relabeling. When the label arrives at the processing station, the conveyor rollers need to be stopped to transport the label so that the label can be accurately processed. Therefore, the rotation of the conveyor rollers needs to be repeatedly paused and started. Over time, this can easily damage the rotating shaft of the conveyor rollers and also results in high energy consumption and high operating costs. Utility Model Content

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a shaft-mounted clamping mechanism, including a mounting plate, wherein a clamping mechanism, a traction mechanism, and a storage mechanism located between the two are provided on the top of the mounting plate;

[0007] The material storage mechanism includes a material storage bracket, which is fixedly installed on the top of the mounting plate. There are two such brackets, which are horizontally symmetrically distributed. A first material storage roller is rotatably installed on each of the two material storage brackets. A second material storage roller is provided below the two first material storage rollers. Both ends of the second material storage roller are rotatably connected to an elastic component. A second electric push rod that extends and retracts in the vertical direction is connected to the elastic component.

[0008] Furthermore, the elastic component includes a connecting plate, the bottom of which is connected to the telescopic end of the second electric push rod, and a sleeve is fixedly installed on the top. A sleeve rod is slidably installed inside the sleeve, a spring is connected to the sleeve rod, and a rotating block is fixedly installed on the top. The rotating block is rotatably connected to the second storage roller.

[0009] Furthermore, limit rings are fixedly installed near the ends of both the first and second storage rollers.

[0010] Furthermore, the clamping mechanism includes a clamping bracket fixedly installed on the top of the mounting plate. The clamping bracket is provided with a first clamping plate and a second clamping plate symmetrically distributed vertically. The first clamping plate and the second clamping plate are connected by a connecting rod assembly. The bottom sides of the first clamping plate are connected with a first electric push rod that extends and retracts vertically.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0025] See attached document Figure 1-4 A shaft-mounted clamping mechanism includes a mounting plate 1, on the top of which a clamping mechanism 2, a traction mechanism 3, and a storage mechanism 4 located between the two are provided;

[0026] The material storage mechanism 4 includes a material storage bracket 41, which is fixedly installed on the top of the mounting plate 1. There are two such brackets, which are horizontally symmetrically distributed. A first material storage roller 42 is rotatably installed on each of the two material storage brackets 41. A second material storage roller 43 is provided below the two first material storage rollers 42. Both ends of the second material storage roller 43 are rotatably connected to an elastic component 44. A second electric push rod 45 that extends and retracts in the vertical direction is connected to the elastic component 44.

[0027] In this embodiment, Figure 1 As shown in the figure, the processing station is located to the left of the clamping mechanism 2. When the label is transported by the traction mechanism 3, and the label arrives at the processing station, the clamping mechanism 2 clamps the label in transit. At this time, the label on the left side of the clamping mechanism 2 stops transporting and can be precisely processed in conjunction with the processing station. Meanwhile, the traction mechanism 3 continues to transport the label on the right side of the clamping mechanism 2. At this time, the second electric push rod 45 is activated to drive the second storage roller 43 to rise, releasing the labels stored on the first storage roller 42 and the second storage roller 43. This allows the traction mechanism 3 to continue transporting the label. After the label is processed, the second electric push rod 45 is activated again to drive the second storage roller 43 to descend and return to its original position. This avoids repeatedly starting the traction mechanism 3, extending its service life and reducing energy consumption. Furthermore, the elastic component 44 allows for adaptive adjustment of the label tension.

[0028] The elastic component 44 includes a connecting plate 441, the bottom of which is connected to the telescopic end of the second electric push rod 45, and a sleeve 442 is fixedly installed on the top. A sleeve rod 443 is slidably installed inside the sleeve 442. A spring 444 is connected to the sleeve rod 443, and a rotating block 445 is fixedly installed on the top. The rotating block 445 is rotatably connected to the second storage roller 43.

[0029] In this embodiment, the spring 444 is used to pull the rotating block 445 so that the sleeve 443 slides downward in the sleeve 442, so that the second storage roller 43 can abut against the label to adjust its tension.

[0030] In the above embodiments, limit rings 5 ​​are fixedly installed near the ends of the first storage roller 42 and the second storage roller 43 to limit the label.

[0031] The clamping mechanism 2 includes a clamping bracket 21 fixedly installed on the top of the mounting plate 1. The clamping bracket 21 is provided with a first clamping plate 22 and a second clamping plate 23 symmetrically distributed vertically. The first clamping plate 22 and the second clamping plate 23 are connected by a connecting rod assembly 24. The bottom sides of the first clamping plate 22 are connected with a first electric push rod 25 that extends vertically. The top sides of the second clamping plate 23 are provided with vertically extending guide rods 26. The guide rods 26 are slidably connected to the clamping bracket 21.

[0032] In this embodiment, after the first electric push rod 25 is activated, the first clamping plate 22 and the second clamping plate 23 can move closer or further apart through the transmission of the connecting rod assembly 24 and the sliding connection between the guide rod 26 and the clamping bracket 21, thereby realizing the clamping and releasing of the label.

[0033] The connecting rod assembly 24 includes a first connecting rod 241 and a second connecting rod 242 respectively hinged to the two ends of the first clamping plate 22 and the second clamping plate 23. The other end of the first connecting rod 241 and the second connecting rod 242 located on the same side is hinged to a third connecting rod 243. The center of the third connecting rod 243 is rotatably connected to the clamping bracket 21.

[0034] In this embodiment, when the first electric push rod 25 extends and pushes the first clamping plate 22 upward, the first connecting rod 241 pulls the third connecting rod 243 to rotate on the clamping bracket 21. The third connecting rod 243 then pulls the second connecting rod 242, so that the second clamping plate 23, in conjunction with the guide rod 26, slides down with the clamping bracket 21, thereby allowing the two first clamping plates 22 and the second clamping plate 23 to move closer to each other. Similarly, when the first electric push rod 25 retracts, it allows the two first clamping plates 22 and the second clamping plate 23 to move away from each other.

[0035] The traction mechanism 3 includes a traction bracket 31 fixedly installed on the top of the mounting plate 1. Two traction rollers 32 are rotatably mounted on the traction bracket 31, which are symmetrically distributed vertically. The rotation shafts of the two traction rollers 32 are meshed with each other through gears 33, and a motor 34 is assembled at the end of one of the rotation shafts.

[0036] In this embodiment, after the motor 34 is started, one of the traction rollers 32 rotates on the traction bracket 31. With the meshing transmission between the two gears 33, the other traction roller 32 will rotate in the opposite direction. The label can be transported by placing it between the two traction rollers 32.

[0037] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.

[0038] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art.
