Description

Technical Field

[0001] This utility model relates to the technical field of material clamping devices, and in particular to a leak-proof device for the discharge port of a ton bag. Background Technology

[0002] In industrial production, ton bags are often used to hold large quantities of bulk materials, such as chemical raw materials and grains. When unloading from a ton bag, the discharge pipe is usually connected to the discharge port of the ton bag. However, because the ton bag is heavy when full and may be subjected to various external forces during unloading, problems such as loosening, leakage, or even detachment may occur at the discharge port. This makes it impossible to guarantee the stability and reliability of the fitting at the discharge port, affecting the efficiency and safety of unloading. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a leak-proof device for the discharge port of a ton bag, which addresses the above-mentioned technical deficiencies. By connecting the discharge port of the ton bag to the inner cylinder and cooperating with the outer cylinder and the cover plate to clamp the outer edge of the discharge port, the stability and reliability of the discharge can be effectively guaranteed, while reducing the occurrence of leakage.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model includes:

[0005] The bracket has an inner cylinder.

[0006] A support plate is connected to a bracket. An outer cylinder concentric with the inner cylinder is provided in the middle. Thrust members are symmetrically provided on both sides of the support plate, and a cover plate is provided between the two thrust members. The cover plate is located below the outer cylinder and is arranged concentrically with the inner cylinder.

[0007] Preferably, the outer cylinder has a protrusion at its lower part, and the cover plate has a groove that mates with the protrusion.

[0008] Preferably, the cover plate is provided with a rubber layer.

[0009] Preferably, the top cross-sectional shape of the protrusion is semi-circular.

[0010] Preferably, guide rods are provided on the support plate on both sides of the outer cylinder, and the guide rods are slidably connected to the cover plate.

[0011] Preferably, the bottom of the guide rod is provided with a limiting plate.

[0012] Preferably, a first hydraulic cylinder is provided below the bracket, and a plurality of movable rods are provided on the support plate that are slidably connected to the bracket. The bottom of each movable rod is provided with a mounting plate that is connected to the first hydraulic cylinder.

[0013] Preferably, the thrust member is provided with an assembly rod, the lower part of which is slidably connected to the cover plate, and the bottom of the assembly rod is provided with a force-bearing spring.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. By inserting the discharge port of the ton bag into the inner cylinder, and cooperating with the outer cylinder and end cap, the discharge port can be well fixed, thereby avoiding problems such as falling off and leakage during the discharge process, and greatly improving the overall stability.

[0016] 2. By using a sliding connection between the support plate and the bracket, the support plate can be lowered as a whole when the material is being assembled, which facilitates the assembly operation and makes it easier for workers to operate.

[0017] 3. The cover plate contacts the bottom of the outer cylinder to clamp the edge of the discharge port, which can effectively ensure the stability of the discharge port during the discharge process. At the same time, the cooperation of the protrusion and the groove can further improve the clamping and fixing of the discharge port.

[0018] 4. The guide rod and the cover plate form a sliding connection, which improves the stability of the cover plate during displacement and the accuracy after installation. The design of the assembly rod and the force spring can prevent excessive clamping force and reduce the requirements for the displacement accuracy of the thrust component.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] Specific implementation method one: Combining Figure 1-6 As shown, the leak-proof device for the ton bag discharge port includes: a bracket 1, on which an inner cylinder 101 is welded and fixed, serving as the discharge pipe during the discharge process; a support plate 2, which can be welded and fixed to the bracket 1, with an outer cylinder 201 concentric with the inner cylinder 101 fixed in the middle, and the outer cylinder 201 having a larger diameter than the inner cylinder 101; thrust members 3 are symmetrically arranged on both sides of the support plate 2, and the thrust members 3 can be hydraulic cylinders or pneumatic cylinders; a cover plate 4 is connected to two thrust members 3 on both sides, and the cover plate 4 has a circular shape in the middle, and is located below the outer cylinder 201, maintaining a concentric arrangement with the inner cylinder 101;

[0028] When unloading is required, the ton bag is lifted to 20cm above the inner cylinder 101. Then, the discharge port of the ton bag is inserted into the inner cylinder 101, with the end reaching the cover plate 4. At the same time, the outer bag at the edge of the discharge port is placed between the outer cylinder 201 and the end cover 4. Then, the thrust component 3 is activated to pull the end cover 4 upward, which, together with the outer cylinder 201, forms a clamping and positioning of the outer bag. This can prevent the discharge port from falling off during the unloading process and avoid leakage, effectively ensuring the stability and safety of the unloading process and facilitating factory use. The outer bag at the edge of the discharge port of the ton bag is nearly circular in shape and is an integral structure with the discharge port, mainly used to assist in positioning the discharge port.

[0029] Preferred embodiments, in combination Figure 4 and Figure 5 As shown, a protrusion 202 is provided below the outer cylinder 201, and a groove 401 that mates with the protrusion 202 is provided on the cover plate 4. During the pressing and clamping process, the protrusion 202 and the groove 401 can form a certain locking and fixing, which improves the stability after clamping.

[0030] Preferred embodiments, in combination Figure 5 As shown, the cover plate 4 is provided with a rubber layer 402, which is distributed on both sides of the groove 401 and is in the shape of a ring. It is made of natural rubber. After contacting the outer bag of the feeding port, it can increase the contact friction and enhance the reliability after clamping.

[0031] Preferred embodiments, in combination Figure 4 and Figure 5As shown, the top cross-section of the protrusion 202 is a semi-circular structure, and the interior of the groove 401 is adapted to it. During the pressing process, edge damage to the feed port can be avoided; a trapezoidal structure can also be used, but there is a possibility of crushing the feed port.

[0032] Preferred embodiments, in combination Figure 2-4 As shown, on both sides of the outer cylinder 201, two guide rods 203 with circular cross sections are fixed on the support plate 2. The guide rods 203 pass through the cover plate 4 to form a sliding connection, which can improve the stability of the displacement of the cover plate 4 and the installation accuracy.

[0033] Preferred embodiments, in combination Figure 3 As shown, the bottom of the guide rod 203 is provided with a limiting plate 204, which is used to limit the maximum downward displacement of the cover plate 4 and prevent it from losing contact with the guide rod 203.

[0034] Preferred embodiments, in combination Figure 1 and Figure 2 As shown, in order to facilitate the fitting of the discharge port and the inner cylinder 101, two first hydraulic cylinders 102 are symmetrically arranged below the bracket 1. At the same time, the support plate 2 is provided with multiple movable rods 205 that are slidably connected to the bracket 1, changing the fixed connection between the two to a sliding connection. The bottom of the movable rod 205 is provided with an mounting plate 206 that is connected to the first hydraulic cylinder 102. By driving the support plate 2 to move down through the first hydraulic cylinder 102, the fitting position of the inner cylinder 101 can be reserved, which is convenient for operation.

[0035] Preferred embodiments, in combination Figure 2 , Figure 3 and Figure 6 As shown, the thrust member 3 is provided with an assembly rod 301. The lower part of the assembly rod 301 is slidably connected to the cover plate 4. At the same time, a force spring 302 is installed at the bottom of the assembly rod 301. The upper part of the force spring 302 contacts the cover plate 4, forming a support for the cover plate 4. When clamping, if a certain clamping force is exceeded, the force spring 302 can be compressed, thereby avoiding excessive clamping force and damage to the discharge port. At the same time, it reduces the requirements for the displacement accuracy of the thrust member 3.

[0036] Regarding the dimensions of components such as the inner cylinder: the inner cylinder 101 is a 5mm thick stainless steel cylinder with a diameter of 20cm; the outer cylinder 201 is a 5mm thick stainless steel cylinder with a diameter of 60cm; the cover plate 4 has a 5mm thick stainless steel circular plate in the middle with a diameter of 80cm, and a circular hole with a diameter of approximately 20cm in the center, which is close to the outer diameter of the inner cylinder 101.

[0037] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
