Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a clamping claw module and a rotary machine. Background Art

[0002] Packaging equipment is often used in the food industry. After filling the food into the packaging bag, the air in the packaging bag is extracted and the bag is sealed after reaching a predetermined vacuum degree. Due to the vacuum packaging, the food can resist oxidation and achieve the purpose of long-term preservation.

[0003] Chinese patent document CN220363520U discloses an automatic film packaging system, which drives multiple material fixing mechanisms to rotate and transport packaging bags through a turntable. Specifically, the turntable is annular, and multiple material fixing mechanisms are arranged on the turntable at intervals around the axis of the turntable. The material fixing mechanisms clamp the bag mouth of the packaging bag through a clamping component. However, due to the limitations of the current technical level, the action frequency of each action link of the above-mentioned machine has reached the limit, and there is almost no room for further improving the working efficiency of the packaging machine.

[0004] In order to improve production efficiency, in the prior art industrial production line, a plurality of parallel production stations are used in some work sections where production efficiency is difficult to improve. For example, Chinese patent document CN117163396A discloses a clamping module and a conveying mechanism, which uses a clamping module with a plurality of parallel clamping jaws to clamp and convey packaging bags.

[0005] In the above scheme, a plurality of first jaws are respectively connected to the first linkage, and a plurality of second jaws are respectively connected to the second linkage. During operation, each of the first jaws can be relatively matched with a corresponding second jaw by relatively moving the first linkage and the second linkage. If there is an error in the installation accuracy of one of the first jaws or the second jaws, the pair of jaws will not be able to effectively clamp the packaging bag. In order to prevent the above problems from occurring, a relatively high installation accuracy is required to install the first jaw and the second jaw, which increases the difficulty of assembly and the cost of assembly. In addition, in the above scheme, the first linkage and the second linkage need to be matched by relative sliding. In a working environment with heavy oil and heavy salt, long-term use is prone to jamming, resulting in problems such as unsmooth movement. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0068] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0069] like Figures 1 to 10 A specific implementation of the clamping jaw module shown includes: a support component 1, multiple groups of clamping jaw components 2, a clamping mechanism, a linkage driving mechanism and a linkage bag opening mechanism.

[0070] like Figure 1As shown, multiple groups of clamping jaw assemblies 2 are arranged at intervals along the length direction of the supporting assembly 1; each group of clamping jaw assemblies 2 is composed of a first clamping jaw structure 3 and a second clamping jaw structure 4 with clamping ends facing each other and arranged at intervals; the clamping end of the first clamping jaw structure 3 is used to clamp the first end of the bag opening of the packaging bag, and the clamping end of the second clamping jaw structure 4 is used to clamp the second end of the bag opening of the packaging bag. The clamping mechanism is arranged between each of the first clamping jaw structure 3 and the second clamping jaw structure 4, and the clamping mechanism provides an independent clamping force tending to a clamping state for the clamping end of each group of clamping jaw assemblies 2. The linkage driving mechanism connects each of the clamping jaw assemblies 2, drives the clamping ends of the first clamping jaw structures 3 and the second clamping jaw structures 4 of the multiple groups of clamping jaw assemblies 2 to overcome the clamping force of the clamping mechanism and be in a loosening state of loosening the ends of the bag openings of multiple packaging bags. The linkage bag opening mechanism is arranged on the supporting assembly 1; drives the first clamping jaw structures 3 and the second clamping jaw structures 4 of the multiple groups of clamping jaw assemblies 2 to reciprocate between a bag opening position close to each other and a bag closing position separated from each other. Specifically, the number of the clamping jaw assemblies 2 can be ten groups, such as Figure 1 shown.

[0071] The clamping module provided in this embodiment has, in the initial state, all the clamping jaw assemblies 2 in a clamping state under the action of the clamping forces respectively provided by the clamping mechanisms, and the clamping mechanism is driven by the linkage driving mechanism to simultaneously drive all the clamping ends to be loosened, the clamping jaw module is in a loosened state, and the bag opening of the packaging bag is placed at the loosened clamping end; then, the linkage driving mechanism drives the clamping mechanism to return to its original position, and no longer drives the clamping end, the clamping end is clamped, and the clamping jaw module resumes the clamping state, and the clamping end clamps the bag opening of the packaging bag. In this embodiment, the clamping mechanism provides independent clamping force for the clamping end of each group of clamping jaw assemblies 2. Therefore, when the first clamping jaw structure 3 and the second clamping jaw structure 4 clamp the end of the bag mouth, there is no need to consider the mutual influence of the installation accuracy of the first clamping jaw structure 3 and the second clamping jaw structure 4. It is only necessary to provide sufficient clamping force for the clamping end of each first clamping jaw structure 3 and each second clamping jaw structure 4, so that the packaging bag can be clamped effectively and reliably, that is, the compensation and smoothness are very good, and the assembly difficulty of the first clamping jaw structure 3 and the second clamping jaw structure 4 are correspondingly reduced, and the assembly cost is reduced. Moreover, compared with the technical solution in the prior art that uses the first and second linkage members to slide relatively to provide the clamping force, the technical solution of the present application clamps the end of the bag mouth more smoothly. At the same time, all the clamping ends are released at the same time through a linkage drive mechanism to release the bag mouth of the packaging bag, thereby reducing the structural complexity of the clamping jaw module, thereby reducing costs and improving work efficiency.

In this embodiment, the torsion spring stably and reliably applies a biasing force to the rotating shaft 8, thereby providing a stable and reliable clamping force for the first clamping member 6 and the second clamping member 7. In other embodiments, the first elastic member 9 can also adopt other forms, not limited to the forms listed in the embodiments of the present application.

[0075] In this embodiment, if Figure 2 and Figure 7As shown, the end of the rotating shaft 8 close to the clamping end is rotatably mounted by a third support 14 fixedly arranged on the clamping frame; the end of the rotating shaft 8 away from the clamping end is rotatably mounted by a support arm 21 fixedly arranged on the clamping frame; the end of the torsion spring fixed relative to the first clamping member 6 is fixed to the third support 14, and the other end of the torsion spring is fixed to the rotating shaft 8 by a stopper 15.

Each of the second clamping jaw structures 4 is fixedly arranged on the second linkage member 11 through the clamping frame, and at this time, the clamping frame is a second support 13. The bag opening actuating mechanism drives the first linkage member 10 and / or the second linkage member 11 to reciprocate between the first clamping jaw structure 3 and the second clamping jaw structure 4 between the bag opening position close to each other and the bag closing position separated from each other.
