Description

Technical Field

[0001] This utility model relates to the technical field of silicone hose processing, and in particular to a one-time molding fiber silicone hose copolymerization device. Background Technology

[0002] Existing fiber-reinforced silicone hoses typically employ a multi-stage, segmented process: "inner tube extrusion → fiber braiding / winding → outer tube coating → secondary vulcanization." However, existing one-step copolymerization equipment combines "continuous fiber reinforcement" and "silicone rubber crosslinking" into a single station, completing fiber pretreatment, co-extrusion compounding, online vulcanization, and sizing traction. During the vulcanization process after co-compounding the fiber hoses, this equipment requires adjustment of the hose's ellipticity to ensure it meets requirements.

[0003] Chinese Patent Application Publication No. CN106989219A, published on July 28, 2017, discloses an expansion hose and its manufacturing process. The hose includes an internal cavity. Its key feature is that the cavity is surrounded by an inner rubber layer, and outside the inner rubber layer is an inner reinforcing layer. The inner reinforcing layer is made of polyester or nylon thread, and a rubber layer with a thickness of 0.25 mm is bonded to one side of it, facing outwards. Outside the inner reinforcing layer is an outer reinforcing layer, which has the same structure as the inner reinforcing layer, with a 0.25 mm thick rubber layer bonded to its thread, facing inwards. Outside the outer reinforcing layer is an outer hose that completely covers the outer reinforcing layer. The drawback of this invention is the lack of a device for adjusting the ellipticity of the hose during production, making it difficult to guarantee the ellipticity of the hose. Utility Model Content

[0004] This invention aims to overcome the shortcomings of existing one-piece molded fiber silicone hoses, which lack an ellipticity adjustment device during copolymerization. It provides a one-piece molded fiber silicone hose copolymerization device that can adjust the ellipticity during the copolymerization process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A one-piece molded fiber silicone tube copolymerization device, comprising: Feed pipe: An extrusion tube, one end of which is connected to a feed tube; A discharge pipe, one end of which is connected to the other end of an extrusion pipe; A negative pressure assembly, the two ends of which are connected to the feed pipe and the discharge pipe respectively, and the negative pressure assembly corresponds to the extrusion pipe.

[0006] The fiber silicone hose enters the feed tube from one end and then enters the extrusion tube from the other end. A negative pressure component corresponding to the extrusion tube ensures a negative pressure environment at the extrusion tube outlet, causing the air pressure inside the hose to squeeze outwards, pressing the hose against the inner wall of the extrusion tube. This adjusts the ellipticity of the hose to match that of the extrusion tube. The air pressure squeezing the inner wall of the hose ensures uniform force distribution within the hose, allowing for better hose adjustment. After adjustment in the extrusion tube, the hose exits from the discharge tube at the other end, achieving the goal of adjusting the ellipticity during the copolymerization and positioning of the hose.

[0007] Preferably, the extrusion tube has several circumferentially distributed connecting holes, and fitting rings are installed at both ends of the extrusion tube. These fitting rings fit against the cross-sections of the feed pipe and discharge pipe on both sides, respectively. The extrusion tube has several finely spaced connecting holes evenly distributed circumferentially, ensuring communication between the inside and outside of the extrusion tube, thereby ensuring a negative pressure environment can be formed inside the extrusion tube. The two ends of the extrusion tube are connected to the end faces of the feed pipe and discharge pipe via the fitting rings, ensuring a tight seal at the interface. This design allows for communication between the extrusion tube and the outside.

[0008] Preferably, the negative pressure assembly includes a combination ring and a negative pressure machine. Two combination rings are provided and respectively placed on both sides of the extrusion tube. The cross-sectional shape of the combination ring is semi-circular, and the sides of the two combination rings are fitted together. The combination rings on both sides of the extrusion tube are detachably connected. A sealing ring is installed at both ends of each combination ring. The outer side of the sealing ring is connected to the combination ring. The inner side of the sealing ring on one side of the combination ring is fitted to the feed pipe, and the inner side of the sealing ring on the other side of the combination ring is fitted to the discharge pipe. A connecting pipe is installed on the combination ring on one side of the extrusion tube, and the negative pressure machine is connected to the combination ring through the connecting pipe. Two combined rings can be combined to form a complete tubular shape. The semi-circular combined rings are connected by fitting together and fixed with bolts. Then, the sealing rings installed at both ends of the combined rings fit into the feed pipe and the discharge pipe respectively, so that the circular tube formed by the combined rings is only connected to the inside of the extrusion tube. Then, the negative pressure machine is connected to the circular tube formed by the combined rings through the connecting pipe, thereby creating a negative pressure environment inside the extrusion tube. This ensures that the hose fits tightly against the inner wall of the extrusion tube. The negative pressure machine is existing technology and can be purchased conventionally, so it will not be described in detail here. This design facilitates the provision of a negative pressure environment.

[0009] Preferably, both the feed pipe and the discharge pipe are equipped with extrusion rings at their ends near the extrusion pipe. These extrusion rings are fitted with sealing rings, and sealing rings are installed on the extrusion rings, positioned between the extrusion rings and the sealing rings. Extrusion rings are installed on both the feed pipe and the discharge pipe, and the two extrusion rings are fitted with sealing rings on both sides of the combined ring. Sealing rings are installed on the sides of the extrusion rings, and are compressed between the extrusion rings and the sealing rings. The elastic sealing rings improve the sealing performance between the combined ring and the feed pipe and discharge pipe. This design enhances the sealing performance at both ends of the combined ring.

[0010] Preferably, the side of the combined ring that is in contact with the other combined ring has a sealing groove, and a sealing strip is provided in the sealing groove. The two sides of the sealing strip are respectively placed in the sealing grooves of the two combined rings. The semi-circular combined ring has a sealing groove on its contact surface, and a sealing strip is installed in the sealing groove. When the two combined rings are connected, the cross-section is squeezed to form the sealing strip. This design can improve the sealing performance of the contact end of the combined ring.

[0011] Preferably, an installation tube is installed on the feed pipe, and the installation tube is fitted onto the feed pipe. One end of the feed pipe is connected to the extrusion ring, and several circumferentially distributed heating plates are installed on the inner wall of the installation tube. By fitting the cylindrical installation tube onto the feed pipe and installing the heating plates on the inner wall of the installation tube, the heating plates do not directly contact the feed pipe; heat is transferred through the air, ensuring more uniform heating. This preheating of the flexible hose inside the feed pipe facilitates adjustment, and the design ensures uniform heating of the feed pipe.

[0012] Preferably, the discharge pipe is equipped with a cooling pipe, which is fitted onto the discharge pipe and sealed at both ends. A water inlet pipe is installed on one side of the cooling pipe, and a water outlet pipe is installed at the upper end. The cooling pipe, with its two ends sealed to the discharge pipe, allows cooling water to be introduced into it through the water inlet pipe. After circulating within the cooling pipe, the cooling water can be output through the water outlet pipe. This circulation process removes heat from the discharge pipe, thus cooling the flexible hose inside. This design effectively cools the discharge pipe.

[0013] The beneficial effects of this utility model are: it can adjust the ellipticity during the copolymerization limiting hose process, it can realize the connection between the extrusion tube and the outside, which is convenient for providing a negative pressure environment, it can improve the sealing performance at both ends of the combined ring, it can achieve uniform heating of the feed tube, and it can cool down the discharge tube.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 , Figure 2 In the illustrated embodiment, a one-piece molded fiber silicone tube copolymerization device includes: Feed pipe 1: Extrusion tube 2, one end of which is connected to feed tube 1; The discharge pipe 3 is connected at one end to the other end of the extrusion pipe 2. The negative pressure component 4 is connected to the feed pipe 1 and the discharge pipe 3 at both ends, and the negative pressure component 4 corresponds to the extrusion pipe 2.

[0018] The extrusion tube 2 is provided with several circumferentially distributed connecting holes 21. Both ends of the extrusion tube 2 are fitted with fitting rings 22, which fit with the cross sections of the feed tube 1 and the discharge tube 3 on both sides, respectively.

[0019] like Figure 3As shown, the negative pressure assembly 4 includes a combination ring 41 and a negative pressure machine 42. There are two combination rings 41, which are respectively placed on both sides of the extrusion tube 2. The cross-sectional shape of the combination ring 41 is semi-circular. The sides of the two combination rings 41 are attached together. The combination rings 41 on both sides of the extrusion tube 2 are detachably connected. Both ends of the combination ring 41 are equipped with sealing rings 43. The outer side of the sealing ring 43 is connected to the combination ring 41. The inner side of the sealing ring 43 on one side of the combination ring 41 is attached to the feed pipe 1, and the inner side of the sealing ring 43 on the other side of the combination ring 41 is attached to the discharge pipe 3. A connecting pipe 44 is installed on the combination ring 41 on one side of the extrusion tube 2. The negative pressure machine 42 is connected to the combination ring 41 through the connecting pipe 44.

[0020] Both the feed pipe 1 and the discharge pipe 3 are equipped with an extrusion ring 11 at one end near the extrusion pipe 2. The extrusion ring 11 is in contact with the sealing ring 43. A sealing ring 12 is installed on the extrusion ring 11 and is placed between the extrusion ring 11 and the sealing ring 43.

[0021] like Figure 4 As shown, a sealing groove 45 is provided on the side of the combined ring 41 that is in contact with the other side of the combined ring 41. A sealing strip 46 is provided in the sealing groove 45, and the two sides of the sealing strip 46 are respectively placed in the sealing groove 45 of the two side combined rings 41.

[0022] like Figure 5 As shown, an installation tube 5 is installed on the feed pipe 1. The installation tube 5 is fitted onto the feed pipe 1. One end of the feed pipe 1 is connected to the extrusion ring 11. Several heating plates 51 arranged in a circular pattern are installed on the inner wall of the installation tube 5.

[0023] like Figure 6 As shown, a cooling pipe 6 is provided on the discharge pipe 3. The cooling pipe 6 is fitted onto the discharge pipe 3 and both ends are sealed to the discharge pipe 3. A water inlet pipe 61 is installed on one side of the cooling pipe 6, and a water outlet pipe 62 is installed at the upper end of the cooling pipe 6.

[0024] When using the device, the hose enters the feed pipe 1 and is heated by the heating plate 51 inside the mounting pipe 5 installed on the feed pipe 1. The heating plate 51 increases the air temperature and then transfers it to the discharge pipe 1. The hose is preheated by increasing the temperature of the discharge pipe 1 and then enters the extrusion pipe 2.

[0025] Then the negative pressure machine 42 works, and the negative pressure machine 42 draws gas from the circular tube composed of the combined rings 41 through the connecting pipe 44, so that the circular tube composed of the combined rings 41 is in a negative pressure state. Since the circular tube composed of the combined rings 41 is connected to the inside of the extrusion tube 2, the negative pressure environment is ensured through the connecting hole 21 on the extrusion tube 2. Then the adsorption hose is attached to the inner wall of the extrusion tube 2. The air pressure adjusts the ellipticity of the hose by the inner extrusion hose attached to the inner wall of the extrusion tube 2.

[0026] After passing through the extrusion tube 2, the flexible tube enters the discharge tube 3. The water in the cooling tube 6 installed on the discharge tube 3 is circulated to cool the discharge tube 3, removing the heat from the discharge tube 3. Then, the flexible tube inside the discharge tube 3 is cooled.
