Description

Technical Field

[0001] This utility model relates to the technical field of ton bag transfer equipment, specifically to a ton bag overhead conveyor transfer packaging sealing device. Background Technology

[0002] Ton bag overhead crane transport refers to the operation of transferring a group of ton bags from the storage area to the work area (such as raw material feeding, finished product delivery, etc.) in a single operation using overhead crane equipment in the raw material or product warehouse. During the ton bag overhead crane transport process, the overhead crane lifting equipment can be used to transfer ton bags in batches, thereby reducing the distance and number of frequent forklift operations, optimizing the feeding and loading process, and significantly improving operational efficiency.

[0003] During the transport of ton bags by overhead crane, it is necessary to ensure that the bag opening is sealed to prevent the material inside from spilling downwards. At the same time, the bag body must be kept undamaged or deformed. Therefore, it is also necessary to use a fixing device that can be used in conjunction with the overhead crane to secure the ton bag and prevent it from sliding or tipping over during the transport process.

[0004] Chinese utility model patent CN221438607U (announcement date: July 30, 2024) discloses a sealing device for ton bag packaging. It includes a base platform, a top platform at the top of the base platform, and a material storage box on the front surface of the base platform. Both the material storage box and the top platform are integrally formed with the base platform. A feeding conveyor and a discharging conveyor are respectively installed on the outer walls of both sides of the top platform, and the supports for the feeding and discharging conveyors are welded to the outer walls of the top platform. The device also includes a central cavity located at the center of the top platform, inside which an electronic scale is placed; and a bearing end plate located on one side of the central cavity. However, based on the accompanying drawings, it is clear that this device is difficult to use in conjunction with overhead crane equipment.

[0005] Based on this, a ton bag overhead crane transfer packaging sealing device is proposed. Utility Model Content

At the same time, it is necessary to keep the bag body undamaged or deformed. Therefore, it is also necessary to use a fixing device that can be used in conjunction with the overhead crane lifting equipment to fix the ton bag to prevent the ton bag from sliding or tipping over during the transfer process. The specific technical solution is as follows:

[0064] Example 1

[0065] like Figures 1-8 As shown in the figure, an embodiment of this utility model provides a ton bag overhead conveyor packaging sealing device, comprising:

[0066] The ton bag transfer box 100 has an open top and is used to hold ton bags filled with materials. It is used to fix and protect the ton bags to prevent them from sliding or tipping over during the transfer process.

[0067] Among them, the ton bags filled with materials can be loaded into the ton bag transfer box 100 by the lifting equipment in the overhead crane (the prior art in the background);

[0068] The cover 200 has a circular groove 210 at the center of its top and is installed at the top opening of the ton bag transfer box 100, so that the bag opening of the ton bag can be exposed outward through the circular groove 210.

[0069] The bag opening closure component is installed on the cover 200. The bag opening closure component can clamp and close the bag opening at the circular groove 210, thereby achieving rapid closure of the bag opening of the ton bag to avoid the problem of material inside the ton bag spilling downwards during the ton bag transportation process.

[0070] Four quick-release locking mechanisms 500 are installed at the four corners between the ton bag transfer box 100 and the cover 200. The four quick-release locking mechanisms 500 can lock and fix the ton bag transfer box 100 and the cover 200.

[0071] Four suspension rings 600 are rotatably installed at the four corners of the top of the cover 200, and are used to engage with the mechanical grippers on the overhead crane. The mechanical grippers on the overhead crane hook the four suspension rings 600 respectively, so that the device can be matched with the overhead crane and the device can be lifted to realize the lifting of the ton bag during the transfer process.

[0072] The overhead crane lifting equipment described in the background art is not shown in the figure. In the prior art, the overhead crane lifting equipment has lifting instruments and mechanical grippers. The mechanical grippers can have four, six, or eight grippers, but four-jaw grippers are still the most common.

[0073] In this embodiment, the top of the ton bag transfer box 100 is open, and the inside can accommodate ton bags filled with materials, so as to fix and protect the ton bags and prevent them from sliding or tipping over during transfer.

[0074] The cover 200 is installed at the top opening of the ton bag transfer box 100, and the bag opening of the ton bag protrudes outward from the circular groove 210;

[0075] The bag opening closure component is installed on the cover 200, which can clamp and close the bag opening at the circular groove 210 to prevent the material inside the ton bag from spilling during transportation;

[0076] Four sets of quick-release locking mechanisms 500 are installed at the four corners between the ton bag transfer box 100 and the cover 200 to lock and fix the two together.

[0077] Four suspension rings 600 are rotatably installed at the four corners of the top of the cover 200, and dock with the mechanical grippers of the overhead crane to realize the lifting of the device.

[0105] The diameter of the locking inner hole 5140 is equal to the diameter of the locking outer hole 5220.

[0106] When each locking block 5120 is snapped into the corresponding locking groove, each locking inner hole 5140 can overlap with the two corresponding locking outer holes 5220 to form a locking channel;

[0107] Each locking component is a locking pin 5230, and each locking pin 5230 is inserted into the corresponding locking channel.

[0108] In this embodiment, the upper part of the locking block 5120 has a locking inner hole 5140, and the U-shaped locking seat 5210 has a locking outer hole 5220 on the opposite side wall.
