Description

Technical Field

[0001] This utility model relates to the technical field of pneumatic lid opening devices, specifically a pneumatic lid opening device. Background Technology

[0002] In industrial fields such as precious metal smelting and chemical reaction, the melting plate machine is a key process equipment. The cover plate of its aluminum box needs to be opened and closed frequently for feeding, observation or maintenance. Pneumatic drive has become a common way of opening the cover due to its sufficient power and convenient control. The traditional pneumatic opening device of the melting plate machine usually uses a cylinder to directly drive the cover plate to rotate around the hinge, which has a simple structure.

[0003] However, this traditional structure has obvious drawbacks: First, in order to ensure the sealing of the melting process and prevent heat and harmful gases from leaking out, the cover plate needs to be well limited and pressed after it is closed. However, the traditional structure often lacks an effective lateral pressing mechanism or requires an additional independent locking device, which leads to cumbersome operation and complex structure. Utility Model Content

[0004] The purpose of this invention is to provide a pneumatic lid opening device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic lid opening device, comprising an aluminum box for a melting plate machine and a lid, wherein a feeding port is provided on the lid, the lid and a connecting plate are fixed to each other, the connecting plate is connected to a lid opening arm, the lid opening arm is rotatably connected to the output end of a cylinder, the cylinder is rotatably connected to the aluminum box for the melting plate machine, and a side positioning mechanism is symmetrically fixed on the aluminum box for realizing the side pressing effect of the lid.

[0006] Preferably, the connecting plate and the fixing plate are rotatably connected, and the fixing plate is fixed on the aluminum box of the melting machine. The rotation between the connecting plate and the fixing plate can provide a basic guarantee for realizing the flipping and opening of the cover plate.

[0007] Preferably, a slider is fixed to the lower end face of the opening arm, and the slider is slidably connected to the connecting plate and the guide rod. Meanwhile, the guide rod is fixed inside the connecting plate. Through the sliding action between the slider, the connecting plate, and the guide rod, the stability of the opening arm's movement relative to the connecting plate can be ensured.

[0008] Preferably, the slider is fixed to one end of the first spring, and the other end of the first spring is fixed inside the connecting plate. Through the elastic action of the first spring, a basic force can be provided for the automatic reset of the slider and the opening arm.

[0009] Preferably, the side positioning mechanism includes vertical plates symmetrically fixed to the upper end face of the aluminum box of the melting plate machine, and inclined pressure plates are provided on the side of the vertical plates. The inclined pressure plates are symmetrically arranged on the aluminum box of the melting plate machine. At the same time, the inclined pressure plates contact the cover plate to achieve positioning. Through the action of the inclined pressure plates, the side of the cover plate can be pressed and fixed when the cover plate is closed, so as to ensure the stability of the cover plate when closed.

[0010] Preferably, the inclined pressure plate is symmetrically fixed with sliding rods on the left and right, and the sliding rods are slidably connected to the vertical plate. When the inclined pressure plate moves under force, the sliding guidance between the sliding rods and the vertical plate can ensure the stability of the movement of the inclined pressure plate.

[0011] Preferably, one end of the slide rod and one end of the second spring are fixed to each other, and the other end of the second spring is fixed to the vertical plate.

[0012] Preferably, the inclined plate is further fixed with an inclined block, and the inclined block and the top rod are slidably connected. The top rod is fixed on the connecting rod, and the connecting rod is symmetrically fixed on the opening arm. The opening arm drives the connecting rod and the top rod to move. With the sliding action between the top rod and the inclined block, the basic force can be provided for the movement of the inclined plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This pneumatic lid opening device perfectly couples the lid opening and closing actions with the loosening and pressing actions of the side positioning mechanism through mechanical linkage. When opening the lid, the cylinder contraction force is first used to overcome the spring force to automatically reset and loosen the side pressure plate. Only after the constraint on the lid is released can the lid be driven to rotate and open, avoiding structural interference and wear caused by forcibly opening the lid. When closing the lid, the lid rotates into place first, and the cylinder thrust is finally converted into lateral pressing force to ensure the stability of the lid after it is closed.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 This utility model provides a technical solution: a pneumatic cover opening device, including a melting plate machine aluminum box 1 and a cover plate 2. The cover plate 2 is provided with a feeding port 3. The cover plate 2 is fixed to a connecting plate 4. The connecting plate 4 is connected to a cover opening arm 6. The cover opening arm 6 is rotatably connected to the output end of a cylinder 8. The cylinder 8 is rotatably connected to the melting plate machine aluminum box 1. A side positioning mechanism 7 is symmetrically fixed on the front and rear of the melting plate machine aluminum box 1 to realize the side pressing effect of the cover plate 2.

[0018] A slider 601 is fixed to the lower end face of the cover arm 6, and the slider 601 is slidably connected to the connecting plate 4, and the slider 601 is slidably connected to the guide rod 602. The guide rod 602 is fixed inside the connecting plate 4. The slider 601 is fixed to one end of the first spring 603, and the other end of the first spring 603 is fixed inside the connecting plate 4. The side positioning mechanism 7 includes a vertical plate 701 symmetrically fixed to the upper end face of the aluminum box 1 of the melting machine, and an inclined pressure plate 702 is provided on the side of the vertical plate 701. The inclined pressure plate 702 is symmetrically arranged on the aluminum box 1 of the melting machine, and the inclined pressure plate 702 contacts the cover plate 2 to achieve positioning. When using this pneumatic lid opening device, such as Figures 1-4As shown, the cover plate 2 is in the closed state at this time, and the inclined pressure plate 702 contacts the side of the cover plate 2 to achieve positioning, ensuring the stability of the cover plate 2 when closed. At this time, the first spring 603 and the second spring 704 are in the contracted state, and the cylinder 8 is in the extended state. When the cover plate 2 is opened, the cylinder 8 is controlled to contract. At this time, because the inclined pressure plate 702 contacts the cover plate 2, the cover plate 2 does not rotate when the cylinder 8 initially contracts. However, due to the elastic action of the first spring 603, the slider 601 slides back to its original position, thereby driving the opening arm 6 to slide back to its original position. With the sliding guidance between the slider 601 and the guide rod 602, the stability of the movement of the opening arm 6 can be ensured until the slider 601 contacts the slotted end on the connecting plate 4. A sliding rod 703 is symmetrically fixed on the inclined pressure plate 702, and the sliding rod 703 is slidably connected to the vertical plate 701; one end of the sliding rod 703 is fixed to one end of the second spring 704, and the other end of the second spring 704 is fixed to the vertical plate 701, and the second spring 704 and the sliding rod 703 are distributed in a one-to-one correspondence; an inclined block 705 is also fixed on the inclined pressure plate 702, and the inclined block 705 is slidably connected to the top rod 706, and the top rod 706 is fixed to the connecting rod 707, while the connecting rod 707 is symmetrically fixed to the cover opening arm 6. When the cover arm 6 slides back to its original position, it simultaneously drives the connecting rod 707 and the push rod 706 to move, causing the push rod 706 to move away from the inclined block 705. With the elastic action of the second spring 704 and the sliding action between the inclined block 705 and the push rod 706, the inclined pressure plate 702 can automatically reset and move away from the cover plate 2. With the sliding guide action between the slide rod 703 and the vertical plate 701, the stability of the movement of the inclined pressure plate 702 can be ensured, thereby releasing the side limiting action of the cover plate 2. When the slider 601 contacts the slotted end of the connecting plate 4, the inclined pressure plate 702 is separated from the side of the cover plate 2. The connecting plate 4 and the fixing plate 5 are rotatably connected, and the fixing plate 5 is fixed on the aluminum box 1 of the melting machine; When the slider 601 contacts the slotted end of the connecting plate 4, the cylinder 8 continues to retract, thereby causing the cover opening arm 6 to be forced to rotate the connecting plate 4 and the cover plate 2, thus realizing the opening of the cover plate 2. Based on the above principle, when the cover plate 2 is closed, during the initial extension of the cylinder 8, the first spring 603 ensures that the opening arm 6, connecting plate 4, and cover plate 2 rotate normally, thereby achieving the closing of the cover plate 2. After the cover plate 2 is closed and positioned in conjunction with the aluminum box 1 of the melting machine, the cylinder 8 continues to extend. With the rotational action between the cylinder 8, the opening arm 6, and the aluminum box 1 of the melting machine, the opening arm 6 is forced to move relative to the connecting plate 4, thereby driving the connecting rod 707 and the top rod 706 to move. With the sliding action between the inclined block 705 and the top rod 706, the inclined pressure plate 702 is forced to move to contact the side of the cover plate 2, thereby achieving the automatic pressing action of the side of the cover plate 2.
