Description

Technical Field

[0001] This utility model belongs to the field of spring hose protective sleeve production technology, and in particular relates to a production device for medical spring hose protective sleeves. Background Technology

[0002] Medical spring cannula protective sleeves are soft tubular objects, typically made of materials such as polyurethane or silicone. The production of these sleeves requires heating and cooling. To improve efficiency, mechanical force is often used instead of manual labor. For example, patent number CN202121442661.1 discloses a technical solution for the production of protective sleeves. This solution uses a mechanical gripper to clamp the protective sleeve and then heat it. While this solution can accomplish the above operations, some problems still exist in actual use. Because the protective sleeve is hollow inside, when the material is heated, the external clamping force does not provide internal support, easily leading to uneven internal stress and heating, causing shrinkage and increasing the defect rate during production. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model provides a production device for protective sleeves of medical spring hoses, which solves the problem of shrinkage caused by uneven heating and stress in the hollow interior during the production of protective sleeves.

[0004] This utility model is implemented as follows: a production device for protective sleeves of medical spring hoses, including a horizontal plate, a mounting plate movably disposed on the lower side of the horizontal plate, and further comprising:

[0005] A clamping assembly, mounted on a mounting plate, is used to clamp the protective sleeve and includes two semi-annular clamping plates that slide on the mounting plate.

[0006] An expansion assembly, mounted on a mounting plate and located between two clamping plates, is used for support inside the protective sleeve and includes several arc-shaped expansion plates arranged at equal angles on the underside of the mounting plate.

[0007] The drive assembly, located on the upper side of the mounting plate, is used to drive multiple expansion plates to expand outward when the two clamping plates are close to each other.

[0008] As a preferred embodiment of this utility model, the clamping assembly further includes a bidirectional screw rotatably disposed inside the mounting plate, and two U-shaped sliding frames are threadedly connected to the bidirectional screw, with the end of the sliding frame away from the bidirectional screw fixed to the clamping plate.

[0009] As a preferred embodiment of this invention, the mounting plate has two guide grooves, and the sliding bracket is disposed within the guide grooves.

[0010] As a preferred embodiment of this utility model, the expansion assembly further includes a lead screw rotatably disposed within the mounting plate. A threaded ring is threaded onto the lead screw and is located on the lower side of the mounting plate. Two retractable limiting rods are disposed between the threaded ring and the mounting plate, and the ends of the limiting rods are fixedly disposed. A sleeve is rotatably disposed on the lead screw. The sleeve and the mounting plate are fixedly connected by two fixing brackets. The threaded ring and the expansion plate are hinged by a first push plate. An installation ring is fixedly disposed at each end of the sleeve, and the installation ring and the expansion plate are hinged by a second push plate.

[0011] As a preferred embodiment of this invention, both the outer surface of the expansion plate and the inner surface of the clamping plate are coated with an oil layer, and the number of expansion plates is at least four.

[0012] As a preferred embodiment of this utility model, the drive assembly includes a drive motor mounted on a mounting plate, the output end of the drive motor being meshed with a bidirectional screw, and the output end of the drive motor being driven by a gearbox, the output end of the gearbox being meshed with a lead screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention uses a drive assembly to bring two clamping plates close together, quickly clamping the protective sleeve. During clamping, the drive assembly simultaneously drives several expansion plates to expand outwards, supporting the inner wall of the protective sleeve. This creates an external clamping and internal support situation between the expansion plates and the clamping plates. When the protective sleeve is heated, it avoids deformation due to external force and heating caused by the sleeve's hollow interior, effectively preventing shrinkage and further ensuring the quality of the protective sleeve during production, thus reducing defective products.

[0022] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 5 As shown in the figure, an embodiment of this utility model provides a production device for protective sleeves of medical spring hoses, including a horizontal plate 1, a mounting plate 2 movably disposed on the lower side of the horizontal plate 1, and further comprising:

[0025] A clamping assembly, mounted on the mounting plate 2, is used to clamp the protective sleeve, including two semi-annular clamping plates 3 that slide on the mounting plate 2;

[0026] An expansion assembly, mounted on the mounting plate 2 and located between two clamping plates 3, is used for support inside the protective sleeve and includes several arc-shaped expansion plates 7 arranged at equal angles on the lower side of the mounting plate 2.

[0027] The drive assembly is located on the upper side of the mounting plate 2 and is used to drive multiple expansion plates 7 to expand outward when the two clamping plates 3 are close to each other.

[0028] As a preferred embodiment of this utility model, the clamping assembly further includes a bidirectional screw 4 rotatably disposed inside the mounting plate 2. Two U-shaped sliding frames 5 are threadedly connected to the bidirectional screw 4. The end of the sliding frame 5 away from the bidirectional screw 4 is fixed to the clamping plate 3, which can effectively drive the two clamping plates 3 to move closer to each other, thereby completing the clamping of the protective sleeve. At the same time, the movement of the two clamping plates 3 away from each other can automatically lower the protective sleeve, realizing the automatic material picking and unloading of the equipment.

[0029] As a preferred embodiment of this utility model, the mounting plate 2 has two guide grooves 6, and the sliding frame 5 is set in the guide grooves 6. During the movement of the clamping plate 3, the two sliding frames 5 move simultaneously. The guide grooves 6 can effectively guide the sliding frames 5, preventing them from shifting during movement and causing the protective sleeve to fail to be clamped.

[0030] As a preferred embodiment of this utility model, the expansion assembly further includes a lead screw 8 rotatably disposed within the mounting plate 2. A threaded ring 9 is threaded onto the lead screw 8 and is located on the lower side of the mounting plate 2. Two telescopic limiting rods 10 are disposed between the threaded ring 9 and the mounting plate 2, and the ends of the limiting rods 10 are fixedly disposed. A sleeve 12 is rotatably disposed on the lead screw 8. The sleeve 12 is fixedly connected to the mounting plate 2 by two fixing brackets 11. The threaded ring 9 and the expansion plate 7 are hinged by a first push plate 13. An mounting ring 14 is fixedly disposed at both ends of the sleeve 12. The mounting ring 14 and the expansion plate 7 are hinged by a second push plate 15. During the clamping process of the clamping plate 3 clamping the protective sleeve, the expansion plate 7 expands simultaneously, thereby forming a state of external clamping and internal expansion of the protective sleeve, avoiding deformation of the protective sleeve during clamping.

[0031] As a preferred embodiment of this utility model, both the outer surface of the expansion plate 7 and the inner surface of the clamping plate 3 are coated with an oil layer, and the number of expansion plates 7 is at least 4, to prevent the protective sleeve from sticking to the clamping plate 3 and the expansion plate 7 after heating.

[0032] As a preferred embodiment of this utility model, the driving assembly includes a driving motor 16 mounted on the mounting plate 2. The output end of the driving motor 16 is meshed with a bidirectional screw 4. The output end of the driving motor 16 is also connected to a gearbox 17. The output end of the gearbox 17 is meshed with a lead screw 8, which facilitates driving the clamping plate 3 to clamp the protective sleeve and simultaneously driving the expansion plate 7 to expand, ensuring greater stability during the clamping process of the protective sleeve and preventing internal heat deformation that could affect the quality of the protective sleeve.

[0033] The working principle of this utility model:

[0034] refer to Figure 1 The initial state of the equipment when the protective sleeve is not clamped; when the equipment needs to clamp, move, and heat the protective sleeve, refer to... Figure 5 The protective sleeve is located between the expansion plate 7 and the clamping plate 3. The clamping plate 3 clamps the protective sleeve, while the expansion plate 7 supports it to prevent the protective sleeve from deforming due to heat. The specific operation method is as follows:

[0035] The protective sleeve is placed between the clamping plate 3 and the expansion plate 7, with the expansion plate 7 inside the protective sleeve and the clamping plate 3 outside the protective sleeve. (Refer to...) Figure 2 The drive motor 16 rotates clockwise, which in turn drives the bidirectional screw 4 and gearbox 17 to rotate clockwise. When the bidirectional screw 4 rotates clockwise, the two sliding frames 5 move closer to each other under the drive of the bidirectional screw 4, that is, the two clamping plates 3 move closer to each other, while referring to... Figure 4The gearbox 17 adjusts the speed of the lead screw 8 by speed regulation. At the same time, when the lead screw 8 rotates, the threaded ring 9 is limited by the limit rod 10 and moves towards the bottom of the lead screw 8. When the threaded ring 9 moves downward, the angle between the threaded ring 9 and the first push plate 13 gradually increases. That is, the first push plate 13 pushes the expansion plate 7 to expand and move away from the lead screw 8 with the end of the second push plate 15 on the mounting ring 14 as the axis. When multiple expansion plates 7 move at the same time, a circular diffusion surface is formed. When the clamping plate 3 moves to the appropriate position, the expansion plate 7 completes expansion at the same time. At this time, the two clamping plates 3 form a clamping force on the protective sleeve, while the expansion plate 7 inside the protective sleeve forms an outward expansion force on it. Then, the clamped protective sleeve can be moved to the position where heating is required. When the protective sleeve needs to be removed, simply drive the drive motor 16 to rotate counterclockwise.

[0036] This invention uses a drive assembly to drive two clamping plates 3 to move closer together, which quickly clamps the protective sleeve. During the clamping process, the drive assembly simultaneously drives several expansion plates 7 to expand outwards. At the same time, the expansion plates 7 support the inner wall of the protective sleeve, so that the expansion plates 7 and the clamping plates 3 form an external clamping and internal support situation. When the protective sleeve is heated, there will be no deformation inside the protective sleeve due to the hollow interior and external force. This effectively avoids the phenomenon of shrinkage inside the protective sleeve, further ensuring the quality of the protective sleeve during production and reducing the generation of defective products.
