Description

TECHNICAL FIELD

[0001] The utility model belongs to ton packaging material technical field, especially related to a ton bag opening device. BACKGROUND

[0002] Some granular, powder material packing transfer usually uses ton bag, and needs to open or open the four around of the top of ton bag when using ton packaging material, so that the raw materials can enter the ton bag. At present, some factories open the ton bag manually, which consumes labor and workers are easy to inhale the dust raised during loading, affecting health. Some factories also open the ton bag through opening device, but most of the existing opening devices are provided with support plates on the top of a containing frame. When using, the ton bag is placed in the containing frame, and then the four around of the top of the ton bag is pulled up above the support plate, and then the top of the ton bag is wound outward to the outside of the support plate, so that the ton bag is kept in the opening state by the friction of the support plate. When ton packaging material, the ton bag will be subjected to the gravity of the raw materials and the impact force when the raw materials fall. Using this opening device, the top of the ton bag is easy to separate from the support plate, and cannot keep the opening state, affecting the loading efficiency, so it is necessary to improve.

When the lifting mechanism drives the first rectangular frame to rise to the maximum limit, the inner side of the first rectangular frame abuts against the top of the four vertical support plates, and the four second protrusions respectively abut against the outward side of the four vertical support plates.

[0010] Furthermore, hinge seats are provided at the four edges of the outer side of the accommodating frame, and the four connecting plates are hinged to the four hinge seats respectively.

[0025] The embodiment of the present application provides a ton bag supporting device, as shown in the figure, comprising an accommodating frame 1, a connecting plate 3, a pushing mechanism and the like. Figures 1-5

[0026] Specifically, the accommodating frame 1 is rectangular, four vertical support plates 2 are arranged in a circumferential array at the top of the accommodating frame 1, the first protrusion 201 is arranged on the outer side of the vertical support plate 2, and the first protrusion 201 has a preset distance between the bottom of the first protrusion 201 and the bottom of the vertical support plate 2; the connecting plate 3 is four, and the four connecting plates 3 are hinged to the outer side of the accommodating frame 1 in a circumferential array, the axial directions of the four connecting plates 3 are respectively parallel to the width directions of the four vertical support plates 2, and the second protrusion 301 is arranged on the top of one side of the connecting plate 3; the pushing mechanism is arranged on the side of the connecting plate 3 away from the second protrusion 301, and is used for pushing the connecting plate 3 upwards. Specifically, referring to Figure 4 The second protrusion 301 is provided with a rubber sheet 302 on the side away from the vertical support plate 2, which is used to increase the friction between the ton bag and the rubber sheet 302.

[0027] In actual use, the ton bag is placed in the accommodating frame 1, then the ton bag is pulled up, so that the top of the ton bag is above the vertical support plate 2, then the top of the ton bag is wound outward, so that the top of the ton bag is hung on the vertical support plate 2 and the first protrusion 201, then the pushing mechanism is controlled to push the connecting plate 3 upwards, so that the top of the ton bag is pressed between the vertical support plate 2 and the second protrusion 301, that is, the ton bag is supported, and the ton bag can be effectively prevented from sliding downward due to the gravity of the material after the ton bag is filled, so that the top of the ton bag is separated from the vertical support plate 2 and the second protrusion 301.

[0028] Specifically, four push cylinders can be selected as the pushing mechanism to push the connecting plate 3 upwards. In an embodiment, referring to Figure 1 Figure 2 ​​The pushing mechanism comprises a first rectangular frame 4 and a pair of lifting mechanisms 401. The first rectangular frame 4 is sleeved outside the accommodating frame 1, and the inner side of the first rectangular frame 4 abuts against the outward side of the plurality of vertical support plates 2. The pair of lifting mechanisms 401 are symmetrically arranged below the first rectangular frame 4 and are used to drive the first rectangular frame 4 to move up and down. When the lifting mechanisms 401 drive the first rectangular frame 4 to rise to the maximum limit, the inner side of the first rectangular frame 4 abuts against the top of the four vertical support plates 2, and the four second protrusions 301 respectively abut against the outward side of the four vertical support plates 2. In this way, only two lifting mechanisms 401 are needed to synchronously push the four connecting plates 3 upward, thereby reducing the power source and lowering the failure rate of the device.

Through this arrangement, when the connecting plates 3 are subjected to a pushing force, the force is transmitted to the four edges of the outer side of the accommodating frame 1, which can improve the stability of the device during use, compared with the four horizontal surfaces of the outer side of the accommodating frame 1 being subjected to a pushing force. Specifically, referring to Figure 2 , the four corners of the inner side of the first rectangular frame 4 are respectively provided with triangular plates 5 in the shape of isosceles right trapezoids, and the side of the triangular plates 5 facing the accommodating frame 1 abuts against the outward side of the vertical support plates 2, which can further improve the stability of pushing the first rectangular frame 4 to move upward.

[0030] Specifically, referring to Figure 1 、 Figure 2 、 Figure 5 , the bottom of the first rectangular frame 4 is provided with a second rectangular frame 6, and the second rectangular frame 6 is fixed outside the accommodating frame 1. The top of the second rectangular frame 6 is circularly arranged with four pairs of guide rods 601, and the top of the first rectangular frame 4 is circularly arranged with four pairs of guide holes. The four pairs of guide rods 601 are respectively arranged in the four pairs of guide holes, which can avoid the first rectangular frame 4 from deviating during upward movement.
