Description

Technical Field

[0001] This utility model belongs to the field of packaging machine technology, specifically relating to an automatic clamping and rotating mechanism. Background Technology

[0002] Currently, during the operation of packaging equipment, after the filled bags are weighed, folded, and sewn, they generally need to be rotated sequentially before being transported to the next workstation. Traditionally, this is done manually or with a multi-functional robotic arm. Manual transport is suitable for small bags, but it increases operating costs. Using a multi-functional robotic arm directly increases production costs, as its installation, maintenance, and repair are more expensive, and its complex structure requires specialized personnel for installation and operation.

[0003] Therefore, this application proposes an automatic clamping and rotating mechanism to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problem that current methods of manually or using robotic arms to transport filled bags of materials to the next workstation directly or indirectly increase operating costs. A brief overview of this invention is provided below to offer a basic understanding of certain aspects of it. It should be understood that this overview is not an exhaustive summary of the invention. It is not intended to identify key or essential parts of the invention, nor is it intended to limit the scope of the invention.

[0006] An automatic clamping and rotating mechanism includes a main frame, a first cylinder, a clamping mechanism, a lifting base, and a rotating swing arm. The cylinder body of the first cylinder is mounted on the main frame, and the telescopic end of the first cylinder is connected to the rotating swing arm. The rotating swing arm is rotatably mounted on the main frame and is connected to the lifting base. Two clamping mechanisms are symmetrically arranged on the lifting base.

[0007] Furthermore, the main frame includes a mounting platform and support legs. The bottom of the mounting platform is stabilized on the ground by multiple support legs. Each support leg is connected to a base at its bottom. A screw is provided on the base and threadedly connected to the support leg. Multiple nuts are provided on the screw and used to support the base and support leg.

[0008] Furthermore, a cylinder mounting seat is provided on the mounting platform. The cylinder body of the first cylinder is hinged to the mounting platform through the cylinder mounting seat. An adapter is connected to the telescopic end of the first cylinder. The adapter is connected to the end of the rotating swing arm through a locking sleeve.

[0009] Furthermore, the clamping mechanism includes a second cylinder and a clamping arm. The cylinder body of the second cylinder is connected to the lifting base through a cylinder connector. The cylinder body of the second cylinder is hinged to the cylinder connector. The telescopic end of the second cylinder is hinged to the middle of the clamping arm. The upper end of the clamping arm is hinged to the lifting base through a rotating shaft.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0019] The connections mentioned in this utility model are divided into fixed connections and detachable connections. Fixed connections (i.e., non-detachable connections) include, but are not limited to, conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include, but are not limited to, conventional disassembly methods such as threaded connections, snap-fit ​​connections, pin connections, and hinged connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can always be found to achieve the function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for fixed connections, and a hinged connection can be chosen for detachable connections.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between 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.

[0021] Example 1, combined with Figures 1-5 This embodiment describes an automatic clamping and rotating mechanism, including a main frame 1, a first cylinder 2, a clamping mechanism 3, a lifting base 4, and a rotating swing arm 5. The cylinder body of the first cylinder 2 is mounted on the main frame 1, and the telescopic end of the first cylinder 2 is connected to the rotating swing arm 5. The rotating swing arm 5 is rotatably mounted on the main frame 1 and is connected to the lifting base 4. Two clamping mechanisms 3 are symmetrically arranged on the lifting base 4.

[0022] The main frame 1 is located downstream of the filling mechanism. The main frame 1 includes a mounting platform 11 and support legs 12. The bottom of the mounting platform 11 is supported on the ground by four support legs 12. The height of each support leg 12 can be adjusted individually. The bottom of the support leg 12 is connected to a base 13. The base 13 is threadedly connected to the support leg 12 by a screw 14. By turning the screw 14, the distance between the base 13 and the support leg 12 is adjusted, thereby adjusting the height of each support leg 12. The four support legs 12 ensure that the mounting platform 11 is in a horizontal state. After adjusting the distance between the support leg 12 and the base 13, the nuts 15 on the screw 14 are turned. The bottom of one nut 15 contacts the upper end face of the base 13, and the upper end face of the other nut 15 contacts the lower end face of the support leg 12. Several more nuts can be turned to make the support leg 12 and the base 13 more stable, ensuring the stability of the main frame 1.

[0023] After the main frame 1 is installed and adjusted, the cylinder body of the first cylinder 3 is connected to the cylinder mounting seat 21 on the mounting platform 11 by means of hinge. The telescopic end of the first cylinder 3 is connected to the locking sleeve 23 through the adapter 22. The locking sleeve 23 is connected to and locked to the rotating swing arm 5 rotatably mounted on the mounting platform 11. The lower half of the rotating swing arm 5 is connected to the lifting seat 4. Two clamping mechanisms 3 are symmetrically arranged on the lifting seat 4. Each clamping mechanism 3 includes a second cylinder 32 and a clamping arm 33. The cylinder body of the second cylinder 32 is hinged to the lifting seat 4 through the cylinder connector 31. The telescopic end of the second cylinder 32 is hinged to the middle part of the clamping arm 33. The clamping arm 33 is connected to the lifting seat 4 through the rotating shaft 34.

[0024] As attached Figure 5 As shown, under normal conditions, the two second cylinders 32 are in a retracted state, and the symmetrically arranged clamping arms 33 are open. When the packaged bag filled with material is below the clamping mechanism 3, the two second cylinders 32 extend simultaneously, and the two symmetrically arranged clamping arms 33 move inward to clamp the packaged bag. Then, the first cylinder 2 on the mounting platform 11 extends, driving the rotating swing arm 5 to rotate, which in turn drives the clamped packaged bag to rotate its angle through the lifting seat 4, thus completing the change of the packaged bag's orientation and angle. This provides a reliable guarantee for the subsequent sealing equipment to meet the requirements of the packaged bag's orientation and placement.

[0025] This embodiment is merely an exemplary illustration of this application and does not limit its scope of protection. Those skilled in the art can make partial changes to it, as long as they do not exceed the spirit and essence of this application, they are all within the scope of protection of this application.
