Description

Technical Field

[0001] This utility model relates to the field of tank manufacturing technology, specifically to an unwinding device for insulation material of liquid helium tanks. Background Technology

[0002] Unwinding refers to releasing raw materials from a roll for subsequent processing. Liquid helium tank insulation materials include three types: foam, fiber, and powder. This solution only improves the unwinding of fiber-type insulation materials, such as glass wool and rock wool. These materials can be harmful to the human body when in extensive contact. Currently, unwinding fiber-type insulation materials requires manual lifting to mount them on an unwinding shaft. This method is not only labor-intensive but also involves significant contact with the glass wool, posing a health hazard. To address these issues, the inventor proposes an unwinding device for liquid helium tank insulation materials. Utility Model Content

[0003] To address the problem that the current unwinding process for fiber-type insulation materials used in liquid helium tanks involves a large amount of labor and involves frequent contact with glass wool, which could pose a health hazard, the purpose of this invention is to provide an unwinding device for liquid helium tank insulation materials.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: a unwinding device for insulation material of liquid helium tank, comprising a base plate, a first groove provided in the middle of the top surface of the base plate, inclined surfaces provided on both sides of the top surface of the base plate and the inclined ends of the inclined surfaces extending to the first groove, a double-ended screw rotatably disposed inside the first groove, a movable seat provided on the top surface of the base plate, a threaded cylinder fixedly connected to the middle of the bottom surface of the movable seat, the threaded cylinder corresponding to and threadedly connected to the double-ended screw, an electric cylinder embedded in the middle of the top surface of the movable seat, a lifting seat fixedly connected to the output shaft end of the electric cylinder, a rotating cylinder rotatably connected to the side wall of the lifting seat, a roller detachably inserted in the rotating cylinder, and a roll of material sleeved on the side wall of the roller.

[0005] Preferably, a motor is provided on one side of the base plate, and the output shaft of the motor is fixedly connected to the rod end of the double-ended screw. A base is provided on the side wall of the motor, and the side wall of the base is fixedly connected to the side wall of the base plate. The motor is installed through the base. When the motor is started, the double-ended screw can rotate under the action of the motor output shaft. Both ends of the double-ended screw are inserted into the base plate and are rotatably connected to the base plate. Protrusions are fixedly connected to both sides of the bottom surface of the movable seat. The bottom surface of the protrusions is provided with a sliding groove. The top surface of the base plate is provided with a second groove. A slide rail is fixedly connected to the inner bottom wall of the second groove. The sliding groove corresponds to and is slidably connected to the slide rail. When the double-ended screw rotates, the two movable seats can move towards each other through the mutual cooperation of the double-ended screw and the threaded cylinder, and the cooperation of the slide rail and the sliding groove.

[0006] Preferably, both sides of the lifting seat are fixedly connected to protruding plates, and the bottom surface of the protruding plates is fixedly connected to guide rods. Both sides of the top surface of the movable seat are fixedly connected to cavity plates. The guide rods are located inside the cavity openings of the cavity plates and are slidably connected to the cavity openings of the cavity plates. A roll of material is placed on one side of the base plate, and the roller shaft of the roll of material corresponds to and cooperates with the opening of the rotating cylinder. The outer shell of the electric cylinder is fixed to the side wall of the movable seat. Activating the electric cylinder can make the lifting seat move up and down. Through the cooperation between the guide rods and the cavity plates, the movement of the lifting seat can be made more stable.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: when unwinding the insulation material for liquid helium tanks, such as when unwinding glass wool rolls in fiber-type insulation materials, the rolls can be automatically lifted and installed for placement, eliminating the need for workers to manually lift the rolls and install them on the unwinding shaft. This effectively reduces the workload of workers and the frequency of workers' contact with glass wool, thereby avoiding excessive contact with glass wool that could cause harm to the human body.

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.

[0015] Example: Figure 1-4 As shown, this utility model provides an unwinding device for insulation material of liquid helium tank, including a base plate 1. A first groove 3 is provided in the middle of the top surface of the base plate 1. Inclined surfaces 2 are provided on both sides of the top surface of the base plate 1 and the inclined ends of the inclined surfaces 2 extend to the first groove 3. A double-headed screw 8 is rotatably installed inside the first groove 3. A movable seat 9 is provided on the top surface of the base plate 1. A threaded cylinder 10 is fixedly connected to the middle of the bottom surface of the movable seat 9. The threaded cylinder 10 corresponds to and is threadedly connected to the double-headed screw 8. An electric cylinder 14 is embedded in the middle of the top surface of the movable seat 9. A lifting seat 15 is fixedly connected to the output shaft end of the electric cylinder 14. A rotating cylinder 18 is rotatably connected to the side wall of the lifting seat 15. A roller 20 is detachably inserted in the rotating cylinder 18. A roll material 19 is sleeved on the side wall of the roller 20.

[0016] A motor 6 is provided on one side of the base plate 1. The output shaft end of the motor 6 is fixedly connected to the rod end of the double-headed screw 8. A base 7 is provided on the side wall of the motor 6. The side wall of the base 7 is fixedly connected to the side wall of the base plate 1.

[0017] By adopting the above technical solution, the motor 6 is installed through the base 7. When the motor 6 is started, the double-headed screw 8 can rotate under the action of the output shaft of the motor 6. Both ends of the double-headed screw 8 are inserted into the base plate 1, and the double-headed screw 8 is rotatably connected to the base plate 1.

[0018] Both sides of the bottom surface of the movable seat 9 are fixedly connected with protrusions 11. The bottom surface of the protrusions 11 is provided with a sliding groove 12. The top surface of the base plate 1 is provided with a second groove 4. The inner bottom wall of the second groove 4 is fixedly connected with a slide rail 5. The sliding groove 12 corresponds to the slide rail 5 and is slidably connected.

[0019] By adopting the above technical solution, when the double-headed screw 8 rotates, the two movable seats 9 can move towards each other through the mutual cooperation between the double-headed screw 8 and the threaded cylinder 10, as well as the cooperation between the slide rail 5 and the slide groove 12.

[0020] Both sides of the lifting seat 15 are fixedly connected with protruding plates 16, and the bottom surface of the protruding plates 16 is fixedly connected with guide rods 17. Both sides of the top surface of the movable seat 9 are fixedly connected with cavity plates 13. The guide rods 17 are located inside the cavity of the cavity plate 13, and the guide rods 17 are slidably connected to the cavity of the cavity plate 13.

[0021] By adopting the above technical solution, a roll material 19 is placed on one side of the base plate 1. The roller shaft 20 of the roll material 19 corresponds to and cooperates with the opening of the rotating drum 18. The outer shell of the electric cylinder 14 is fixed to the side wall of the movable seat 9. Activating the electric cylinder 14 can make the lifting seat 15 move up and down. Through the cooperation between the guide rod 17 and the cavity plate 13, the lifting seat 15 can move more smoothly.

[0022] Working principle: When using this utility model, the roll 19 to be unwound is placed on the base plate 1. The inclined surface 2 makes it easy for the worker to guide the roll 19 to the middle of the top surface of the base plate 1. The electric cylinder 14 is activated so that the lifting seat 15 falls until the opening of the rotating drum 18 corresponds to the roller shaft 20 of the roll 19.

[0023] Next, the motor 6 is started, and the double-headed screw 8 can rotate under the action of the output shaft of the motor 6. Through the cooperation between the double-headed screw 8 and the threaded cylinder 10, and the cooperation between the slide rail 5 and the slide groove 12, the two movable seats 9 can move towards the roll material 19 so that the opening of the rotating cylinder 18 is sleeved on the roller shaft 20 of the roll material 19.

[0024] Then, the electric cylinder 14 is controlled again to make the lifting seat 15 move up and down. Through the cooperation of the rotating cylinder 18 and the roller shaft 20 on the roll 19, the roll 19 can be lifted so that the roll 19 is separated from the base plate 1. The rotating cylinder 18 can make the roll 19 rotate so as to cooperate with the external traction device to unwind the roll 19.

[0025] After the unwinding operation is completed, only the roller 20 remains on the roll 19. The overall weight is relatively light. The operator only needs to hold the remaining roller 20 and control the motor 6 to reverse so that the double-headed screw 8 reverses, thereby causing the two movable seats 9 to move away from the roller 20, so that the roller 20 is disengaged from the opening of the rotating drum 18, and the roller 20 can be removed.

[0026] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
