Description

Technical Field

[0001] This invention relates to the field of silicone rubber cable technology, and more specifically to an ultraviolet irradiation machine for the production of non-adhesive silicone rubber cables. Background Technology

[0002] Chinese patent CN111534106A discloses a novel method for preparing high-temperature vulcanized silicone rubber cables. The preparation method includes S1 mixing into agglomerates; S2 continuing mixing; S3 dispersing and stirring; S4 thin-wall swelling; S5 vulcanization molding; and S6 post-molding treatment. The silicone rubber obtained by the above preparation method can quickly eliminate internal air bubbles during the preparation process and prevent air bubble formation for a long time. The effects of crosslinking agents, catalysts, and defoamers on the curing time, electrical insulation properties, and physical properties of additive high-temperature vulcanized silicone rubber are observed, especially for micro, thin-walled, multi-cavity medical silicone rubber, which greatly improves the resistivity of the vulcanized rubber.

[0003] Silicone rubber is widely used as insulation or sheathing material for wires and cables due to its environmental friendliness, flexibility, good resistance to high and low temperatures, and excellent mechanical properties. It is particularly prevalent in the medical cable industry. However, due to the unique molecular chain structure of silicone rubber, the surface of the cable after production has a certain degree of stickiness, which easily leads to surface contamination and a rough feel to the touch. A common solution is to add a coating material to the cable surface, but medical cables are frequently wiped with alcohol for disinfection, causing the coating material to easily peel off. Furthermore, when using existing silicone rubber for UV curing, uneven irradiation is common, and the heat generated by the UV lamp during prolonged exposure not only affects the lifespan of the UV lamp but also alters the curing temperature of the rubber on the cable surface. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned above in the background art, and to propose an ultraviolet irradiation machine for the production of non-adhesive silicone rubber cables.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An ultraviolet irradiation machine for the production of non-adhesive silicone rubber cables includes a feed tube, an ultraviolet lamp box, an ultraviolet lamp mounting plate, and ultraviolet lamps;

[0007] The UV lamp box has a guide tube on each side for conveying silicone rubber cable. There are mounting plates on the inner walls of both sides of the UV lamp box. The mounting plates are connected to the connecting sleeves, and the connecting sleeves are fitted onto the guide tubes accordingly.

[0008] The mounting plate has a cable through hole in the middle and a cable positioning component, which includes a limiting wheel, a sliding groove, a mounting block, a limiting rod, and a spring. The mounting plate has a sliding groove arranged in a ring array on the side wall away from the guide pipe. A limiting rod is installed in the sliding groove. One end of the limiting rod extends to the cable through hole in the mounting plate and is connected to the limiting wheel. The other end of the limiting rod is connected to the mounting block. The limiting rod is slidably connected to the mounting plate. A spring is sleeved on the limiting rod. One end of the spring is connected to the inner wall of the sliding groove, and the other end of the spring is connected to the mounting block.

[0009] A UV lamp mounting plate is connected between the corresponding mounting blocks on the two mounting plates, and a UV lamp is installed on the UV lamp mounting plate.

[0010] As a further embodiment of the present invention, the mounting plate is a ring-shaped plate.

[0011] As a further aspect of the present invention: a connecting sleeve passes through the side wall of the ultraviolet lamp box and is rotatably connected to the ultraviolet lamp box, the connecting sleeve being driven by a pulley assembly, and the other connecting sleeve being rotatably connected to the inner wall of the ultraviolet lamp box.

[0012] As a further aspect of the present invention: a heat dissipation mechanism is provided on the surface of the ultraviolet lamp mounting plate;

[0013] The heat dissipation mechanism includes condenser pipes, heat conduction plates, heat dissipation plates, condensation chambers, telescopic sleeves, and sealing rings. Condenser pipes are installed on both sides of the condensation chamber. A heat conduction plate is installed on the side wall of the UV lamp mounting plate away from the UV lamp. A heat dissipation plate is installed on the side of the heat conduction plate away from the UV lamp mounting plate. Multiple heat dissipation plates are arranged side by side and extend into the condensation chamber. Annular grooves that match the heat dissipation plates are provided on the side wall of the condensation chamber.

[0014] As a further aspect of the present invention: the condenser box has an annular hollow structure and is installed on the inner wall of the ultraviolet lamp box.

[0015] As a further aspect of the present invention: the inner cavity of the condenser is provided with a ring array of multiple partitions, which divide the cavity into multiple condensation chambers.

[0016] As a further aspect of the present invention: the condenser tube includes a condensate inlet tube and a condensate outlet tube, which are symmetrically installed on both sides of the condensation chamber.

[0017] As a further aspect of the present invention: each heat sink is fitted with a telescopic sleeve, the bottom of the telescopic sleeve is connected to the heat conduction plate, the top of the telescopic sleeve is connected to the sealing ring, and the sealing ring is slidably fitted on the heat sink.

[0018] As a further aspect of the present invention: the sealing ring is located at the annular groove and is rotatably connected to the side wall of the condenser.

[0019] The beneficial effects of this invention are:

[0020] This invention uses cyanuric chloride and resorcinol as raw materials to produce intermediate 1, which exhibits excellent UV radiation resistance. Then, using intermediate 1 and 6-(4-hydroxy-3,5-di-tert-butylphenylamino)-2,4-di-n-octylthio-1,3,5-triazine as raw materials, an active chlorine atom is replaced in intermediate 1 to produce intermediate 2. 1,6-(4-hydroxy-3,5-di-tert-butylphenylamino)-2,4-di-n-octylthio-1,3,5-triazine is a high-molecular-weight, multifunctional thiohedral hindered antioxidant. The agent exhibits strong compatibility and possesses the dual functions of both primary and secondary antioxidants, enabling intramolecular synergy and blending synergy with other antioxidants, resulting in excellent antioxidant effects. Furthermore, this 1,6-(4-hydroxy-3,5-di-tert-butylphenylamino)-2,4-di-n-octylthio-1,3,5-triazine is suitable for post-processing stabilization of cable rubber, protecting the material from thermal oxidative degradation during production, processing, and final use. The resulting intermediate 2 not only possesses UV resistance but also excellent antioxidant properties.

[0021] Finally, using intermediate 2 and diethylenetriamine as raw materials, a functional additive was obtained through a nucleophilic substitution reaction. This functional additive not only has anti-ultraviolet radiation and anti-oxidation properties, but also flame retardant properties. In addition, the prepared functional additive has good compatibility with cable rubber. As a result, the prepared cable has multiple advantages of anti-ultraviolet radiation, anti-oxidation and flame retardancy, which greatly extends the service life of the cable.

[0022] The ultraviolet irradiation machine of this invention allows the mounting plate equipped with ultraviolet lamps to rotate in a ring around the ultraviolet lamps, uniformly irradiating the surface of the cable. At the same time, the four limiting wheels clamp and stabilize the cable, and the limiting wheels can clamp and position cables of different diameters through limiting rods and springs. When clamping cables of different diameters, the ultraviolet lamps on the mounting block have been displaced, so that the ultraviolet lamps always maintain a suitable irradiation distance from the cable.

[0023] Furthermore, a heat dissipation mechanism is provided on the surface of the UV lamp mounting plate, which can effectively solve the problem that the UV lamp will generate heat during long-term irradiation, which will not only affect the lifespan of the UV lamp, but also change the process temperature of the rubber curing process on the cable surface; the heat dissipation plate of this heat dissipation mechanism can change the length of the heat dissipation plate in the condensation box according to the change of the cable diameter, thereby changing the overall heat dissipation area of ​​the UV lamp, so that the heat dissipation mechanism is directly proportional to the diameter of the cable.

[0072] Comparative Example 1

[0073] Comparative Example 1 uses a silicone rubber cable with Chinese patent number CN109206920B;

[0074] The performance of the silicone rubber cables of Examples 1-3 and Comparative Example 1 was tested, and the test results are as follows:

[0075] The test results are shown in the table below:

[0076]

[0077] As can be seen from the data in the table above, the functional additives of the present invention can enable the rubber protective sheath of silicone rubber cables to have excellent UV resistance, oxidation resistance and flame retardancy.

[0078] Example 7

[0079] Please see Figure 1-5 As shown, based on the above embodiments 1-3, after the silicone rubber cable is vulcanized, the cable reel is placed on the pay-off frame, and then passed through the ultraviolet irradiation machine. The ultraviolet irradiation machine irradiates the surface of the cable, and finally the cable is wound onto the take-up frame.

[0080] The ultraviolet irradiation machine includes a feed tube 1, an ultraviolet lamp box 2, a connecting sleeve 3, a pulley group 4, a mounting plate 5, an ultraviolet lamp mounting plate 7, and an ultraviolet lamp 8.

[0081] The UV lamp box 2 is provided with a guide tube 1 on each side. The guide tube 1 is used to convey the silicone rubber cable. There are mounting plates 5 on the inner walls of both sides of the UV lamp box 2. The mounting plates 5 are connected to the connecting sleeves 3. The connecting sleeves 3 are correspondingly fitted on the guide tubes 1.

[0082] Mounting plate 5 is an annular plate with a cable through hole in the middle. A cable positioning component is provided on mounting plate 5, including a limiting wheel 12, a sliding groove 13, a mounting block 14, a limiting rod 15, and a spring 16. The sliding groove 13 is arranged in an annular array on the side wall of mounting plate 5 away from the guide pipe 1. A limiting rod 15 is provided in the sliding groove 13. One end of the limiting rod 15 extends to the cable through hole in the mounting plate 5 and is connected to the limiting wheel 12. The other end of the limiting rod 15 is provided with a mounting block 14. The limiting rod 15 is slidably connected to the mounting plate 5. A spring 16 is sleeved on the limiting rod 15. One end of the spring 16 is connected to the inner wall of the sliding groove 13, and the other end of the spring 16 is connected to the mounting block 14.

[0083] A UV lamp mounting plate 7 is connected between the corresponding mounting blocks 4 on the two mounting plates 5, and a UV lamp 8 is installed on the UV lamp mounting plate 7.

[0084] One of the connecting sleeves 3 passes through the side wall of the ultraviolet lamp box 2 and is rotatably connected to the ultraviolet lamp box 2. The connecting sleeve 3 is connected to the pulley group 4 for transmission. The other connecting sleeve 3 is rotatably connected to the inner wall of the ultraviolet lamp box 2.

[0085] During operation, the cable enters through one guide tube 1 and exits through another guide tube 2. It also passes through the limiting wheels 12 on the mounting plate 5 and is positioned between the four limiting wheels 12. It is then conveyed upward along the guide tube 1. Simultaneously, the pulley group 4 is activated, driving the corresponding connecting sleeve 3 to operate. This causes the mounting plate 5, which is equipped with ultraviolet lamps 8, to rotate in a circle around the ultraviolet lamps, uniformly irradiating the surface of the cable. At the same time, the four limiting wheels 12 clamp and stabilize the cable, and the limiting wheels 12 can clamp and position cables of different diameters through the limiting rod 15 and the spring 16. When clamping cables of different diameters, the ultraviolet lamps 8 on the mounting plate 4 are displaced, ensuring that the ultraviolet lamps 8 always maintain a suitable irradiation distance from the cable.

[0086] Example 8

[0087] Based on the above embodiment 7, the ultraviolet lamp 9 will generate heat during long-term irradiation, which will not only affect the service life of the ultraviolet lamp 9, but also change the process temperature of the curing of the rubber on the cable surface; therefore, a heat dissipation mechanism is provided on the surface of the ultraviolet lamp mounting plate 7.

[0088] The heat dissipation mechanism includes a condenser pipe 6, a heat-conducting plate 9, a heat dissipation plate 10, a condensation box 11, a telescopic sleeve 17, and a sealing ring 18. The condensation box 11 has an annular hollow structure and is installed on the inner wall of the ultraviolet lamp box 1. The condenser pipe 6 is provided on both sides of the condensation box 11. The heat-conducting plate 9 is provided on the side wall of the ultraviolet lamp mounting plate 7 away from the ultraviolet lamp 8. The heat dissipation plate 10 is provided on the side of the heat-conducting plate 9 away from the ultraviolet lamp mounting plate 7. Multiple heat dissipation plates 10 are arranged side by side and extend into the condensation box 11. The side wall of the condensation box 11 is provided with an annular groove that matches the heat dissipation plate 10.

[0089] The condenser 11 has multiple baffles arranged in a ring array in its inner cavity, which divide it into multiple condensing chambers. The condenser pipe 6 includes a condensate inlet pipe and a condensate outlet pipe, which are symmetrically installed on both sides of the condensing chamber. This allows the condensing medium to enter the condensing chamber from the condensate inlet pipe and then exit from the condensate outlet pipe into the refrigerator, thus achieving cyclic condensation.

[0090] Each heat sink 10 is fitted with a telescopic sleeve 17. The bottom of the telescopic sleeve 17 is connected to the heat conduction plate 9, and the top of the telescopic sleeve 17 is connected to the sealing ring 18. The sealing ring 18 is slidably fitted on the heat sink 10 and is located at the annular groove. It is rotatably connected to the side wall of the condensation box 11. The structure of the sealing ring 18 has a sealing effect, which can effectively prevent or reduce the overflow of condensing medium from inside and outside the condensation box 11 into the ultraviolet lamp box 2, thereby affecting the curing temperature of the cable. The setting of the telescopic sleeve 17 ensures that when the ultraviolet lamp mounting plate 7 undergoes displacement, the sealing ring 18 is always on the side wall of the ultraviolet lamp box 2, and the position of the sealing ring 18 will not change.

[0091] During operation, the heat generated by the UV lamp 8 is evenly transferred from the heat-conducting plate 9 to each heat dissipation plate 10. The condensing medium enters the condensation chamber from the condensate inlet pipe and then exits from the condensate outlet pipe. The heat transfer between the condensing medium and the heat dissipation plates 10 achieves the function of cooling the UV lamp 8. Furthermore, the length of the heat dissipation plate 10 in the condensation box 11 can be changed according to the cable diameter, thereby changing the overall heat dissipation area of ​​the UV lamp 8. That is, when the cable diameter is large, it will drive the limiting rod 15 to move along the slide groove 13, and cause the UV lamp mounting plate 7 to move closer to the condensation box 11. This will cause the heat dissipation plate 10 to continue to be inserted into the inner cavity of the condensation box 11 along the annular groove, increasing the length of the heat dissipation plate 10 in the condensation box 11, thereby increasing the heat dissipation area. Thus, the heat dissipation mechanism is directly proportional to the cable diameter.

[0092] The working principle of this invention is as follows: the cable enters from one guide tube 1 and exits from another guide tube 2. It also passes through the limiting wheel 12 on the mounting plate 5 and is located between the four limiting wheels 12. It is conveyed upward along the guide tube 1. At the same time, the pulley group 4 is started to work, which drives the corresponding connecting sleeve 3 to work. This causes the mounting plate 5, which is equipped with ultraviolet lamp 8, to rotate in a circle along the ultraviolet lamp, so as to irradiate the surface of the cable evenly.

[0093] Meanwhile, the heat generated by the UV lamp 8 during operation is evenly transferred from the heat conduction plate 9 to each heat dissipation plate 10. The condensing medium enters the condensing chamber from the condensate inlet pipe and then exits from the condensate outlet pipe. The heat transfer between the condensing medium and the heat dissipation plate 10 achieves the function of cooling the UV lamp 8.

[0094] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
