Description

Technical Field

[0001] This utility model relates to bagging equipment, specifically to a material clamping and bagging mechanism for a bagging machine. Background Technology

[0002] A bagging machine is a device used for automated opening and filling of packaging bags. The bagging mechanism is mainly used to feed the material to be filled into the opened packaging bag. Traditional bagging mechanisms typically feed stacked materials to a feeding platform, then control a pusher to push the material into the packaging bag. This structure has drawbacks in practical use: for some lighter and softer materials, the pusher can cause deformation during the compression process, and it can also easily lead to the stacked material becoming loose and shifting, affecting the bagging quality of subsequent materials. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by this utility model is to provide a clamping and bagging mechanism for a bagging machine to solve the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A material clamping and bagging mechanism for a bagging machine includes a feeding platform, characterized in that: a movable frame is provided at the discharge end corresponding to the feeding platform, the movable frame is connected to a movable drive component, and a gripper assembly is provided on the movable frame, the gripper assembly being used to clamp the stacked materials on the feeding platform and then drive the materials to move and be fed into the opened packaging bag.

[0006] The active drive assembly includes a rotating shaft connected to a movable frame. One end of the rotating shaft is connected to a swing arm, and the other end of the swing arm is hinged to the piston rod of a first cylinder. The rotating shaft, the swing arm, and the first cylinder are all mounted on a movable frame, which is connected to the sliding part of a linear motor.

[0007] The gripper assembly includes a lower gripper fixedly mounted on the movable frame, and an upper gripper corresponding to the lower gripper. The upper gripper is mounted on a swing member, which is hinged to the movable frame and connected to the swing drive assembly.

[0008] The swing drive assembly includes a second cylinder, the cylinder body of which is mounted on a movable frame, and the piston rod of the second cylinder is hinged to the swing component.

[0009] A spring connects the swinging component to the movable frame.

[0010] Two movable frames are arranged on the left and right sides.

[0011] The discharge end of the corresponding feeding platform is equipped with a guide plate with a guide slope.

[0012] The above-mentioned technical solution provides a material clamping and bagging mechanism for a bagging machine. By setting a gripper assembly on the movable frame, the stacked materials can be positioned and clamped first. Then, the material is fed into the open packaging bag by controlling the movement of the movable frame. This effectively avoids the material being squeezed and deformed, and ensures that the material will not become loose or shifted, thus effectively improving the bagging quality of the stacked materials. Attached Figure Description

[0013] The present invention includes the following figures:

[0014] Figure 1 This is a structural diagram of the present invention installed in the whole machine;

[0015] Figure 2 for Figure 1 A magnified view of the area pointed to by A in the middle. Detailed Implementation

[0016] As shown in the figure, the present invention discloses a material clamping and bagging mechanism for a bagging machine, including a feeding platform 1, a movable frame 4 corresponding to the discharge end of the feeding platform 1, the movable frame 4 being connected to a movable drive component, and a gripper assembly being provided on the movable frame 4. The gripper assembly is used to clamp the stacked materials on the feeding platform 1 and then drive the materials to move and be fed into the opened packaging bag.

[0017] Furthermore, the movable drive assembly includes a rotating shaft 3 connected to the movable frame 4. One end of the rotating shaft 3 is connected to the swing arm 10, and the other end of the swing arm 10 is hinged to the piston rod of the first cylinder 11. The rotating shaft 3, the swing arm 10, and the first cylinder 11 are all mounted on the movable frame 12, which is connected to the sliding part of the linear motor 13. By controlling the first cylinder 11 to drive the swing arm 10 to swing, the rotating shaft 3 can be rotated, thereby driving the movable frame 4 to swing up and down. Of course, in addition to this swinging method, the cylinder can also be used to directly drive the movable frame 4 to lift and lower to achieve the up and down movement of the gripper assembly. This gripper can be set to be longer to grip a larger area of ​​material and improve the stability of the gripping. By controlling the linear motor 13, the movable frame 4 and the gripper assembly can be driven to move back and forth as a whole. Of course, in addition to using a linear motor, common linear drive structures such as cylinders, motor-driven gear and rack structures, and synchronous belt structures can also be used to achieve the back and forth movement of the movable frame 4.

[0018] Furthermore, the gripper assembly includes a lower gripper 7 fixedly mounted on the movable frame 4, and an upper gripper 8 corresponding to the lower gripper 7. The upper gripper 8 is mounted on the swing member 9, and the upper gripper 8 and the swing member 9 are integrally formed for easy assembly and processing. The swing member 9 is hinged to the movable frame 4 and connected to the swing drive assembly. In this embodiment, the swing drive assembly includes a second cylinder 5, the cylinder body of which is mounted on the movable frame 4, and the piston rod of the second cylinder 5 is hinged to the swing member 9. By controlling the second cylinder 5 to drive the swing member 9 and the upper gripper 8 to swing and cooperate with the lower gripper 7, the stacked materials can be clamped or released. Of course, in addition to using the swing method, a cylinder or other structure can also be used to drive the upper gripper to rise and fall, which can also cooperate with the lower gripper 7 to clamp or release the materials.

[0019] Furthermore, a spring 6 connects the swinging component 9 to the movable frame 4. This allows the swinging component 9 to quickly reset, thus enabling the material to be released quickly.

[0020] Furthermore, two movable frames 4 are arranged on the left and right sides. This enables two gripper assemblies to hold the material, further improving the stability and reliability of material holding.

[0021] Furthermore, a guide plate 15 with a guide slope 14 is provided at the discharge end of the feeding platform 1. With the above structure, when the material is delivered to the feeding platform 1, it will first be fed onto the guide plate 15 so that the lower gripper 7 can extend under the material and cooperate with the upper gripper 8 to clamp the material; of course, a clearance groove can also be provided at the corresponding position of the feeding platform 1 for the lower gripper 7 to extend into, which can also allow the lower gripper to extend under the material.

[0022] The working principle of this utility model is as follows: the stacked materials are fed to the feeding end of the feeding platform 1, and then the movable frame 4 is controlled to swing down, so that the gripper assembly swings to the rear side of the stacked materials. Then the movable frame 12 is controlled to drive the movable frame 4 and the gripper assembly to move, so that the gripper assembly moves to the stacked materials and clamps the rear side of the materials. Then the movable frame 12 is controlled to drive the gripper assembly to continue to move, clamping the materials and feeding them into the opened packaging bag to realize the bagging operation of the materials.
