Description

Technical Field

[0001] The utility model belongs to the technical field of automatic batching production lines, and particularly relates to an automatic sealing device for unpacking. Background Art

[0002] In the existing PAC / PAM flocculant unpacking station device used in ship water treatment systems, there are problems of insufficient automation and lack of protection in design. Specifically, during actual operation on ships, the unpacking station device cannot automatically respond to open and requires manual intervention, which not only increases the operation complexity but also reduces work efficiency. In an operating environment where flocculants need to be added frequently, this defect is particularly inconvenient. The design of the unpacking station fails to fully consider the convenience of unpacking materials in case of package breakage, resulting in a cumbersome operation process that may require additional tools or equipment for assistance, further increasing labor costs and time costs. After unpacking, the device lacks an automatic closing mechanism and cannot effectively prevent the intrusion of rainwater or other external water sources. Once rainwater seeps into the interior of the unpacking station, it will not only cause water accumulation but also may trigger a series of chain reactions. Flocculants such as PAC / PAM are prone to dissolve and form colloids in a humid environment, and these colloids will then harden and adhere to various components of the unpacking station and the conveying system. In severe cases, it can cause the entire system to become blocked, even damage key valves, and ultimately lead to the paralysis of the entire unpacking and conveying system. For this reason, an automatic sealing device for unpacking is proposed. Summary of the Utility Model

[0024] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] The following describes in detail the specific implementation of the present utility model in conjunction with specific embodiments.

[0026] As Figures 1-3 shown, an automatic sealing device for unpacking provided by an embodiment of the present utility model includes an unpacking hopper 1, a hinged assembly, a sealing cover plate 2, a cylinder 6 and a cylinder support seat 5;

[0027] The hinged assembly is installed on the unpacking hopper 1 and serves to support the sealing cover plate 2;

[0028] A connecting rod portion is fixed to the tail of the sealing cover plate 2, which forms a simple crank - connecting rod mechanism with the cylinder 6. When the cylinder 6 extends, the sealing cover plate 2 drops and presses on the upper part of the unpacking hopper 1 to seal the unpacking hopper 1. When the cylinder 6 contracts, the sealing cover plate 2 opens.

[0029] The cylinder 6 is hinged to the cylinder support seat 5. By injecting compressed air into the cylinder 6 and cooperating with the opening and closing control of the solenoid valve, the cylinder 6 can generate powerful power, providing a power source for the opening and closing of the sealing cover plate 2.

[0030] In the embodiment of the present utility model, the device can be automatically opened during unpacking to allow materials to enter the unpacking hopper; it is closed in the non - use state to ensure the sealing and dryness of the device.

[0031] The cylinder 6 uses a magnetic switch to sense the switch state, ensuring that it is in the closed state when not in use usually. If it is not in the closed state, a signal is sent to remind the personnel to check, improving the safety of equipment use.

[0032] When the PLC control system receives an instruction to open the sealing cover plate 2, it sends a signal to the solenoid valve to open the solenoid valve and allow compressed air to enter one side of the cylinder 6. As the compressed air enters, the piston rod of the cylinder 6 will extend or contract accordingly. Through the connecting rod portion connected thereto, the sealing cover plate 2 is pushed to rotate and open along a preset trajectory. On the contrary, when it is necessary to close the sealing cover plate 2, the PLC control system sends a signal to the solenoid valve to change the flow direction of the compressed air, thereby driving the piston rod of the cylinder 6 to move in the reverse direction and driving the sealing cover plate 2 to rotate and close.

[0033] As Figure 1 and Figure 3 shown, as a preferred embodiment of the present utility model, the unpacking hopper 1 includes a carbon steel conical hopper, support legs, unpacking knives, inspection doors and a screen. A soft seal is provided at the upper part of the unpacking hopper 1; the carbon steel conical hopper is fixed on the support legs; the unpacking knives are installed at the inlet for cutting open the ton bags; the inspection doors are provided for daily inspection and maintenance; the screen is installed at the outlet of the unpacking hopper 1 for filtering large pieces of materials and sundries; the soft seal ensures the sealing performance of the unpacking hopper when not in use.

[0034] As Figure 1 and Figure 2 shown, as a preferred embodiment of the present utility model, the cylinder support seat 5 is fixed on the support legs of the unpacking hopper 1 to provide stable support for the cylinder 6. Ensure that the cylinder 6 is stable and does not shake during operation, and ensure the accuracy and reliability of the switching action.

[0035] In the embodiment of the present utility model, a marine crane is used to lift the ton bag to the inlet of the unpacking hopper 1. The ton bag will be cut open by the unpacking knives, and the materials in the ton bag will flow into the unpacking hopper 1. Large pieces of materials and sundries such as rope heads are filtered through the screen and then enter the lower feeding equipment. In addition, an air exchange pipeline is provided. When the unpacking station is running, it can be connected to the dust collector through this pipeline to ensure centralized treatment of the dust escaping during unpacking.

[0036] As Figure 1 and Figure 2 shown, as a preferred embodiment of the present utility model, the hinge assembly includes a hinge shaft 3 and a hinge seat 4; hinge holes are provided on the sealing cover plate 2. The hinge shaft 3 passes through the hinge holes of the sealing cover plate 2 and is fixed on the unpacking hopper 1 by the hinge seat 4. The sealing cover plate 2 is connected to the unpacking hopper 1 through the hinge shaft 3 and the hinge seat 4, and can realize the rotation of the sealing cover plate 2 along the hinge shaft 3 to meet the use requirement of opening and closing by 115°.

[0037] In the embodiment of the present utility model, when the sealing cover plate 2 is in the closed state, it closely fits on the hopper opening of the unpacking hopper 1 to ensure the sealing performance. When it is opened, the sealing cover plate 2 will rotate and form an angle of 115° with the inlet of the unpacking hopper 1. By precisely controlling the opening and closing angle of the sealing cover plate 2 at 115°, the safety of the equipment during operation is ensured. When the sealing cover plate is opened to 115°, it can not only meet the space requirement for unpacking operations, but also avoid equipment damage or safety hazards that may be caused by excessive opening.

[0038] The working principle of the present utility model is:

[0039] For the automatic sealing device used for unpacking, the PLC controls the cylinder 6 to contract, drives the sealing cover plate 2 to open through the connecting rod part, and prepares to receive the bulk bag. Use a marine crane to lift the bulk bag to the inlet of the unpacking hopper 1, and cut the bulk bag with an unpacking cutter. The materials in the bulk bag flow into the unpacking hopper 1, filter out large pieces of materials and sundries through the sieve, and then enter the lower feeding device. During the unpacking process, if it is necessary to stop the operation or the equipment is not in use, the PLC controls the cylinder 6 to extend, and the sealing cover plate 2 closes to ensure the sealing of the unpacking hopper 1. When the unpacking station is running, it is connected to the dust collector through the air exchange pipeline to centrally process the escaped dust.

[0040] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
