Description

Technical Field

[0001] This utility model belongs to the technical field of unloading station equipment, specifically relating to a liftable bag clamping mechanism for a ton bag unloading station. Background Technology

[0002] A ton bag is a flexible, medium-sized bulk container that is convenient for transporting large quantities of bulk powdery materials. It features large capacity, light weight, and easy loading and unloading.

[0003] In existing technologies, when unpacking ton bags, the ton bag is hoisted up and then the bottom of the ton bag is ripped open using a sharp tearing tool to allow the material inside to fall freely. Alternatively, a simple bag clamping mechanism is used manually to hold the bottom outlet of the ton bag. However, manual clamping is quite dangerous. If the hoisting part slips and the ton bag falls directly, it can cause injury or death. In addition, some bag clamping mechanisms lack lifting functions, making it extremely inconvenient to operate when it is necessary to connect to the neck of the ton bag. It is difficult to accurately adapt to different height requirements. Furthermore, after clamping, some bag clamping mechanisms are prone to wrinkles at the bag opening due to structural design defects, which affects the smoothness of unloading and may even lead to material blockage. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides a lifting bag clamping mechanism for a ton bag unloading station, including a frame, a slide rail, a lifting component, a ton bag body and a lifting bag clamping mechanism.

[0005] The lifting assembly is a winch. A hook is fixedly connected to the output end of the winch. A semi-ring is movably connected to the hook. A cross hanger is fixedly connected to the side surface of the semi-ring. A support frame is provided on the upright frame. A bag mouth tube is fixedly connected to the inner side wall of the support frame. An electric telescopic rod one is fixedly connected to the inner bottom wall of the bag mouth tube. A bracket is fixedly connected to the output end of the electric telescopic rod one. An electric telescopic rod two is fixedly connected to the inner side wall of the bracket. A clamping plate is fixedly connected to the output end of the electric telescopic rod two.

[0006] The above technical solution defines the mechanism as consisting of a frame, slide rail, winch, ton bag body, and lifting and clamping mechanism. The winch, through the connection of hooks, semi-rings, and cross hangers, constructs the lifting and transmission path of the ton bag body. The bag opening tube, together with electric telescopic rod one, bracket, electric telescopic rod two, and clamping plate, achieves precise clamping and wrinkle removal at the ton bag outlet. Electric telescopic rod one can actively adjust the height of the bracket, and together with electric telescopic rod two and clamping plate, clamps and smooths wrinkles at the ton bag outlet, solving the problems of bag opening blockage and leakage during unloading and improving the smoothness of unloading.

[0007] The present invention is further configured such that the slide rail is mounted on the upright, the upper surface of the ton bag body is provided with an array of ton bag hooks, and the lower surface of the ton bag body is provided with a ton bag discharge port.

[0008] With the above technical solution, the slide rail is installed on the upright frame to provide a horizontal displacement track for the winch, so that the ton bag body can be quickly transferred from the ground hoisting area to the upright unloading area. There is no need for manual handling and alignment of the ton bag, which reduces labor intensity and improves the efficiency of ton bag transfer before unloading.

[0009] The present invention is further configured such that a limiting part is provided at the end of the cross-shaped hanger, and a controller is fixedly connected to the side surface of the upright.

[0010] Through the above technical solution, the end limiting part of the cross-shaped lifting frame can restrict the position of the ton bag hook, avoid the risk of the ton bag falling due to the ton bag hook falling off during lifting, and improve the safety of lifting operations.

[0011] The present invention is further configured such that a first crossbar is fixedly connected to the side surface of the upright frame, a first cylinder is rotatably connected to the side surface of the first crossbar via a connector, and a second crossbar is fixedly connected to the side surface of the upright frame.

[0012] The present invention is further configured such that a side support frame is rotatably connected to the side surface of the second crossbar, and the output end of the first cylinder is rotatably connected to the side support frame through a connector.

[0013] Through the above technical solution, the first and second crossbars provide the installation foundation for the cylinder and the side support frame, forming an auxiliary support system on the side of the upright frame. When the ton bag is hoisted to the unloading area of ​​the upright frame, the side support frame can be rotated and unfolded. In conjunction with the extension and retraction of the first cylinder, it provides lateral support for the ton bag body during unloading, thereby offsetting the lateral tension of the ton bag body during unloading.

[0014] The present invention is further configured such that the bag opening tube is a hollow cylindrical structure, and an opening and closing door is rotatably connected to the side surface of the bag opening tube.

[0015] Using the above technical solution, the tie-down strap of the ton bag outlet inside the bag opening can be removed by opening the door.

[0016] The present invention is further configured such that the number of the electric telescopic rod one, the electric telescopic rod two, and the clamping plate are two and arranged symmetrically.

[0017] The present invention is further provided with a connecting tube at the lower end of the bag opening tube.

[0018] The beneficial effects of this utility model are as follows:

[0019] The ton bags are precisely hooked by a cross-shaped hanger, and the lifting components flexibly lift and transfer them. With the help of the slide rails, the ton bags are quickly positioned on the upright frame. The electric telescopic rod one, bracket, electric telescopic rod two, and clamping plate work together to clamp the ton bag's discharge port and smooth out wrinkles in real time, ensuring smooth unloading. The entire process combines automation and manual operation, improving unloading efficiency, avoiding material residue, and the height-adjustable clamping plate is suitable for different ton bags, reducing labor intensity and ensuring stable, efficient, and environmentally friendly unloading.

Under the action of the electric telescopic rod 21, the two clamping plates 22 move in opposite directions to clamp or open the ton bag outlet 10 for unloading. After clamping, under the action of the electric telescopic rod 19, the clamping plates 22 are adjusted up and down to flatten the wrinkles and avoid affecting the unloading, ensuring smooth unloading. The whole process combines automation and manual operation to improve unloading efficiency and avoid material residue. The height-adjustable clamping plates 22 are adapted to different ton bag bodies 8, reducing labor intensity and ensuring stable, efficient and environmentally friendly unloading.

[0033] The working principle of this utility model is as follows: When unloading the material in the ton bag body 8, the cross hanger 6 is used to hook the ton bag hook 9 of the ton bag body 8, and then the winch 3 is used to lift the ton bag body 8 away from the ground, so that the winch 3 moves on the slide rail 2 and moves the ton bag body 8 to the middle of the stand 1. The height of the ton bag body 8 is adjusted so that the ton bag outlet 10 enters the bag mouth cylinder 17.
