Description

Technical Field

[0001] This utility model relates to the field of condom manufacturing technology, and in particular to a water-based lubricant filling mechanism for polyurethane condom production. Background Technology

[0002] In the production process of polyurethane condoms, the water-based lubricant application step is crucial. Polyurethane condoms are highly favored in the market due to their thinness, high strength, and good thermal conductivity. To ensure a good user experience and reliable safety while meeting the needs of efficient production, water-based lubricant must be applied to the condom surface precisely and evenly.

[0003] In the prior art, the water-based lubricant filling mechanism for polyurethane condom production adopts a filling head filling design. The filling tube is usually connected to a storage tank for storing water-based lubricant at one end, and fixedly connected to the filling head at the other end, forming a closed delivery channel. The lubricant in the storage tank is powered by a pump and delivered to the filling head through the filling tube. The filling head then applies the lubricant to the surface of the condom.

[0004] However, existing technologies have significant problems in handling the production of condoms of different sizes. With the diversification of market demand, the specifications of polyurethane condoms are constantly increasing. Different specifications of condoms have significant differences in mold size and placement during production. However, the existing fixed-height dispensing head is difficult to adapt to the production needs of multiple specifications. When producing condoms of different sizes, the inflexible height of the dispensing head makes it difficult to ensure that the lubricant is accurately applied to the appropriate position on the condom. Furthermore, polyurethane condoms are relatively thin, and if the height of the dispensing head is not appropriate, it is very likely to have excessive contact or compression with the condom surface during operation. This excessive contact or compression can cause the condom to break or deform, resulting in a large number of defective products. This not only reduces the product qualification rate but also greatly affects production efficiency and increases production costs. Therefore, a water-based lubricant dispensing mechanism for polyurethane condom production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a water-based lubricant filling mechanism for polyurethane condom production, which aims to improve the problem that the height of the lubricant filling head cannot be conveniently adjusted in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A water-based lubricant filling mechanism for polyurethane condom production includes a connecting column, a base plate at the bottom of the connecting column, an adjusting component on the inner wall of the connecting column, a connecting plate fixedly connected to the top of the connecting column, a filling tube fixedly connected to the inner wall of the connecting plate, a filling head on the outer wall of the filling tube, and a quick-release component on the inner wall of the filling head.

[0008] The adjusting assembly includes a sliding column, the outer wall of which is slidably connected to the inner wall of the connecting column, the top of the base plate being fixedly connected to the bottom of the sliding column, a limiting groove being formed inside the sliding column, a locking block being slidably connected to the inner wall of the connecting column, the outer wall of the locking block being slidably connected to the inner wall of the limiting groove, a limiting block one being fixedly connected to the outer wall of the locking block, a reset assembly being provided inside the connecting column, a connecting rod being fixedly connected to the outer wall of the limiting block one, the outer wall of the connecting rod being slidably connected to the inner wall of the connecting column, and a pulling block being fixedly connected to one end of the connecting rod;

[0009] As a further description of the above technical solution:

[0010] The reset assembly includes a spring, one end of which is fixedly connected to the inner wall of the connecting column, and the other end of which is fixedly connected to the outer wall of the limiting block.

[0011] As a further description of the above technical solution:

[0012] The quick-release assembly includes a retaining ball, the outer wall of which is slidably connected to the inner wall of the filling head, and a retaining groove is provided inside the filling tube;

[0013] As a further description of the above technical solution:

[0014] The outer wall of the ball is slidably connected to the inner wall of the slot, and a sealing block is slidably connected to the inner wall of the filling tube. A limit block three is fixedly connected to the top of the sealing block.

[0015] As a further description of the above technical solution:

[0016] A spring three is installed inside the filling tube. One end of the spring three is fixedly connected to the inner wall of the filling tube, and the other end of the spring three is fixedly connected to the outer wall of the limiting block three.

[0017] As a further description of the above technical solution:

[0018] The bottom of the sealing block is in contact with the inner wall of the filling head, and a retaining ring is fixedly connected to the outer wall of the filling head;

[0019] As a further description of the above technical solution:

[0020] A sliding block is slidably connected to the outer wall of the fixed ring, and a limit ring is fixedly connected to the inner wall of the sliding block;

[0021] As a further description of the above technical solution:

[0022] The outer wall of the filling head is fitted with a second spring. One end of the second spring is fixedly connected to the outer wall of the limiting ring, and the other end of the second spring is fixedly connected to the outer wall of the fixing ring. The outer wall of the filling head is fixedly connected with a second limiting block.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the height of the dispensing head is adjusted by moving the locking block out of the limiting groove and then sliding on the outer wall of the sliding column via the connecting column. This avoids the problem that when producing condoms of different specifications, the mold size and placement are different, and the fixed height dispensing head is difficult to adapt to the production of various specifications of products. In addition, polyurethane condoms are relatively thin, and if the height of the dispensing head is not appropriate, it will have excessive contact or compression with the surface of the condom, causing the condom to break or deform. This improves the versatility and production efficiency of the equipment, reduces product damage caused by mechanical contact, and increases the product qualification rate.

[0025] 2. In this utility model, the limiting ring releases the limiting of the ball, and then the ball moves out of the slot, achieving the effect of quick disassembly of the dispensing head. This avoids the problem that the traditional connection between the dispensing head and the dispensing pipe is mostly fixed by threads or flanges, which requires tools such as wrenches and screwdrivers for disassembly, and each disassembly and installation takes a long time. When the production line needs to change dispensing heads of different specifications, clean blockages, or repair worn parts, frequent disassembly will lead to accumulated downtime and reduce production efficiency. Therefore, the dispensing head can be quickly disassembled without tools, reducing downtime. Attached Figure Description

[0034] 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.

[0035] Reference Figures 1-3 An embodiment of this utility model provides a water-based lubricant filling mechanism for polyurethane condom production, including a connecting column 1, a base plate 2 at the bottom of the connecting column 1, an adjusting component on the inner wall of the connecting column 1, a connecting plate 3 fixedly connected to the top of the connecting column 1, a filling tube 4 fixedly connected to the inner wall of the connecting plate 3, a filling head 5 on the outer wall of the filling tube 4, and a quick-release component on the inner wall of the filling head 5.

[0036] The adjustment assembly includes a sliding column 6, whose outer wall is slidably connected to the inner wall of a connecting column 1, allowing the connecting column 1 to slide up and down along the outer wall of the sliding column 6, thereby driving the filling head 5 to adjust its height. The top of the base plate 2 is fixedly connected to the bottom of the sliding column 6. Limiting grooves 7 are linearly arranged inside the sliding column 6, providing multiple positioning points for the locking block 8 to achieve different height fixations. A locking block 8 is slidably connected to the inner wall of the connecting column 1, and the outer wall of the locking block 8 is slidably connected to the inner wall of the limiting grooves 7. When the locking block 8 engages in different positions of the limiting grooves 7, the connecting column 1 can be fixed at the corresponding height, thereby adjusting the height of the filling head 5. A limiting block 9 is fixedly connected to the outer wall of the locking block 8, used to limit the locking block 8. The sliding range prevents the locking block 8 from falling off the inner wall of the connecting column 1. A reset component is provided inside the connecting column 1. A connecting rod 11 is fixedly connected to the outer wall of the limiting block 9. The outer wall of the connecting rod 11 is slidably connected to the inner wall of the connecting column 1. A pulling block 12 is fixedly connected to one end of the connecting rod 11. The reset component includes a spring 10. One end of the spring 10 is fixedly connected to the inner wall of the connecting column 1, and the other end of the spring 10 is fixedly connected to the outer wall of the limiting block 9. When the operator pulls the pulling block 12, the spring 10 is compressed and stores elastic potential energy. When the pulling block 12 is released, the spring 10 releases elastic potential energy, pushing the limiting block 9 and the locking block 8 to move towards the limiting groove 7, so that the locking block 8 is re-locked into the limiting groove 7, thus completing the height fixation.

[0037] Reference Figures 4-6The quick-release assembly includes a retaining ball 15, the outer wall of which is slidably connected to the inner wall of the filling head 5. A groove 13 is provided inside the filling tube 4, and the outer wall of the retaining ball 15 is slidably connected to the inner wall of the groove 13. When the retaining ball 15 is engaged in the groove 13, the filling head 5 and the filling tube 4 can be fixedly connected together to prevent the filling head 5 from falling off during operation. A sealing block 20 is slidably connected to the inner wall of the filling tube 4, and a limiting block 21 is fixedly connected to the top of the sealing block 20. The limiting block 21 is used to restrict the sealing block. The sliding range of the sealing block 20 is limited to prevent it from sliding out of the inner wall of the filling tube 4. A spring 22 is installed inside the filling tube 4. One end of the spring 22 is fixedly connected to the inner wall of the filling tube 4, and the other end is fixedly connected to the outer wall of the limiting block 21. The elastic force of the spring 22 pushes the sealing block 20 downwards, causing the bottom of the sealing block 20 to fit tightly against the inner wall of the filling head 5, thus achieving a sealing effect and preventing lubricant leakage from the connection between the filling tube 4 and the filling head 5. The bottom of the sealing block 20 and... The inner wall of the filling head 5 is fitted together, and a fixing ring 14 is fixedly connected to the outer wall of the filling head 5. A sliding block 17 is slidably connected to the outer wall of the fixing ring 14. A limit ring 18 is fixedly connected to the inner wall of the sliding block 17. The sliding block 17 can slide up and down along the outer wall of the fixing ring 14, and the limit ring 18 is fixedly connected to its inner wall. The limit ring 18 is used to limit the position of the ball 15 and prevent the ball 15 from falling out of the slot 13. A second spring 16 is sleeved on the outer wall of the filling head 5, and one end of the second spring 16 is fixedly connected to... The outer wall of the limiting ring 18 and the other end of the spring 16 are fixedly connected to the outer wall of the fixed ring 14. When the sliding block 17 moves down, the spring 16 is compressed and stores elastic potential energy. When the sliding block 17 is released, the spring 16 releases the elastic potential energy, pushes the sliding block 17 to reset, and then drives the ball 15 to lock into the slot 13. The outer wall of the filling head 5 is fixedly connected to the limiting block 19. The limiting block 19 is used to limit the lowest position of the sliding block 17 and prevent the ball 15 from falling out of the filling head 5.

[0038] Working principle: When adjusting the height of the filling head 5, firstly, pulling the pulling block 12 causes the connecting rod 11 to slide on the inner wall of the connecting column 1. Then, the sliding of the connecting column 1 causes the limiting block 9 to move, which in turn compresses the spring 10. Then, the movement of the limiting block 9 causes the locking block 8 to move out of the limiting groove 7, thereby releasing the limiting of the connecting column 1. Subsequently, the connecting column 1 slides on the outer wall of the sliding column 6, adjusting the height of the filling head 5 until it reaches the desired height. When the position is appropriate, release the pull block 12. The spring 10 will cause the limit block 9 to reset. Then, the reset of the limit block 9 will cause the locking block 8 to move into the limit groove 7, thereby limiting the sliding column 6. This avoids the difficulty of adapting the fixed-height filling head 5 to the production of various sizes of condoms due to different mold sizes and placement positions. In addition, polyurethane condoms are relatively thin. If the height of the filling head 5 is not appropriate, it will have excessive contact or compression with the condom surface, causing the condom to break or deform.

[0039] When disassembling the filling head 5, first pull down the sliding block 17. Pulling the sliding block 17 moves the limiting ring 18, which then compresses the second spring 16. When the bottom of the sliding block 17 contacts the top of the second limiting block 19, the limiting ring 18 releases the limiting of the retaining ball 15. The disassembly of the filling head 5 is completed when the retaining ball 15 moves out of the retaining groove 13. After disassembly, the rebound of the third spring 22 moves the third limiting block 21, which in turn moves the sealing block 20 back to its original position. When installing the filling head 5, first insert the inner wall of the filling head 5 into the outer wall of the filling tube 4. When the sealing block 20 contacts the inner wall of the filling head 5, the third limiting block 21 slides inside the filling tube 4. Then, the third limiting block 21 slides inside the filling tube 4. The movement of 1 compresses the spring 22, and the rebound force generated by the compression of the spring 22 drives the limit block 21 to move. The movement of the limit block 21 then causes the sealing block 20 to press against the inner wall of the filling head 5. Then the sliding block 17 is released, and the rebound of the spring 2 16 drives the limit ring 18 to reset. Subsequently, the limit ring 18 presses against the ball 15, causing it to slide on the inner wall of the filling head 5. When the ball 15 moves into the slot 13, the installation of the filling head 5 is completed. This avoids the traditional connection between the filling head 5 and the filling pipe 4, which is mostly fixed by threads or flanges. Disassembly requires the use of tools such as wrenches and screwdrivers, and each disassembly and installation takes a long time. When the production line needs to replace different specifications of the filling head 5, clean blockages, or repair worn parts, frequent disassembly will lead to the accumulation of production line downtime and reduce production efficiency.
