Description

Technical Field

[0001] This utility model relates to the field of marine equipment manufacturing and processing technology, specifically a processing and production equipment for thermoplastic elastomers in marine equipment. Background Technology

[0002] The processing and production of thermoplastic elastomers for marine equipment typically includes the following steps: First, raw material preparation involves selecting suitable thermoplastic elastomer resins, such as styrene, polyolefins, and polyurethanes, and adding plasticizers, fillers, stabilizers, and other additives according to product performance requirements. Then, these raw materials are added to a mixer or twin-screw extruder for mixing, ensuring thorough and uniform mixing to form a compound with good processing properties. Next is the molding process, where different molding methods are selected based on the specific shape and requirements of the product. For example, injection molding is suitable for... For the production of complex-shaped marine equipment parts, such as seals and handles, the mixture is heated to 160-220℃ in a heating cylinder to melt it, and then injected into the mold cavity under high pressure of 50-150MPa through a screw. After cooling and shaping (cooling time 10-60 seconds), the product is demolded to obtain the product. Extrusion molding is often used to produce continuous profiles, such as sealing strips and hoses. The mixture is heated to 180-250℃ in a screw extruder to plasticize it, and then extruded through a die to form a continuous shape. It is then water-cooled or air-cooled to shape, and then wound or cut as needed.

[0003] However, in the current processing and production of tubular marine equipment thermoplastic elastomers, during the water-cooling and shaping stage, the tube body needs to be cooled by water to achieve rapid and uniform solidification. However, existing water-cooling systems lack rapid synchronous control capabilities and cannot adjust the spray flow rate synchronously and accurately according to the real-time changes in the tube radius. When the tube diameter increases, the larger surface area requires more cooling water to ensure the cooling effect. However, if the system maintains the original flow rate, it will lead to insufficient water cooling. This not only prolongs the cooling time of the tube body and reduces production efficiency, but may also cause uneven internal structure of the tube body due to insufficient cooling, affecting the mechanical properties and dimensional accuracy of the product, resulting in a decline in product quality. Conversely, when the tube diameter decreases, a large amount of cooling water is not needed, but the system still sprays according to the initial set flow rate, and a large amount of water resources are wasted. This not only increases production costs, but also causes unnecessary consumption of resources in the process of large-scale production, which is not in line with the concept of sustainable development.

[0004] Therefore, this utility model provides a processing and production equipment for thermoplastic elastomers for marine equipment to solve the above problems. Utility Model Content

When the tube diameter increases, the opening of the conical valve hole on the valve seat increases, and more cooling water enters from the input interface of the water-cooled pipe, flows through the water hole on the surface of the conical valve body to the nozzle, and sprays onto the surface of the tube, ensuring that the tube body cools and solidifies quickly and evenly, avoiding uneven internal structure due to insufficient water cooling, effectively improving the mechanical properties and dimensional accuracy of the product, and reducing the defect rate; when the tube diameter decreases, the valve hole opening decreases, reducing water waste while avoiding the potential impact of over-cooling on product quality.

After the cutting is completed, the piston push rod compresses the spring in the hydraulic channel and resets under the action of the spring force, driving the lower cutting machine to reset, realizing automatic circulation, and can efficiently perform equidistant cutting of the lower section of the pipe body.

[0024] 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.

[0025] Please see Figures 1-4 A processing and production equipment for thermoplastic elastomers for marine equipment includes a conveying structure 1, and a cutting structure 2 is fixedly arranged above the front side of the conveying structure 1.

[0026] The conveying structure 1 includes a frame 11. A conveying roller 12 is rotatably mounted on the lower part of the conveying channel inside the frame 11, fitted with a bearing seat. The front axle end of the conveying roller 12 extends out of the frame 11 and is fixed to a drive ratchet 121. Inside the conveying channel of the frame 11, a conveying auxiliary roller 13 is movably connected to the upper side of the conveying roller 12, fitted with a bearing seat and a spring fixed below the bearing seat. A trigger rod 131 is fixedly mounted on the upper surface of the bearing seat of the leftmost conveying auxiliary roller 13, with its upper end inserted into the interior of a water-cooling pipe 15. The water-cooling pipe 15 is fixedly mounted on the upper surface of the frame 11's box plate, and a valve seat 151 is fixedly mounted inside the water-cooling pipe 15 at the upper end of the trigger rod 131. A valve seat 151 for inputting cooling water into the water-cooling pipe 15 is positioned below the valve seat 151 on the side of the water-cooling pipe 15. The input interface has a conical valve hole inside the valve seat 151. Initially, a conical valve body 153 is sealed inside the valve hole. The conical valve body 153 is slidably disposed inside the water cooling pipe 15. The conical valve body 153 is gyro-shaped, and several through water holes are arranged in a ring array along the axis on the surface of the conical valve body 153. A spring rod 152 with telescopic capability is fixedly disposed between the lower surface of the conical valve body 153 and the upper surface of the valve seat 151 to limit and reset the sliding of the conical valve body 153 inside the water cooling pipe 15. At least one nozzle is installed at the output end of the water cooling pipe 15, and all nozzles point to the surface of the marine equipment being conveyed. The rear shaft end of the leftmost conveying roller 12 is connected to the drive motor 14 through a coupling, and the drive motor 14 is bolted to the rear side of the frame 11.

[0027] The cutting structure 2 includes a sliding box 21, which is bolted to the upper front side of the frame 11. The sliding box 21 has an I-shaped groove 211 inside, and a toothed plate 223 is slidably mounted inside the groove 211. A piston rod 224 is fixedly mounted on the right side of the toothed plate 223. The piston end of the piston rod 224 inserts into a hydraulic channel 212 on the right side of the sliding box 21 and slides along the inner wall of the hydraulic channel 212. A connecting interface is provided on the right side of the sliding box 21 at the right end of the hydraulic channel 212. The toothed plate 223 is also I-shaped, and a mounting base 221 is slidably mounted on its upper surface. The left and right sides of the rear surface of the mounting base 221 and the left and right sides of the front surface above the toothed plate 223 all have mounting brackets. The display panel is fixedly equipped with hydraulic rods 222 with hydraulic telescopic capability. The hydraulic rods 222 consist of hydraulic pipes, pistons, and hydraulic springs sleeved on the pistons. The front end of the hydraulic pipes is provided with an interface that communicates with the inside of the pipes. The interface is connected to the interface of the hydraulic channel 212 through a pipeline. The right side of the hydraulic channel 212 is provided with a spring whose right end is fixed to the inner wall of the hydraulic channel 212. The upper surface of the mounting base 221 is bolted to the lower cutting machine 22. The lower cutting machine 22 does not have a conveying auxiliary roller 13 above the conveying roller 12 in its moving range. The drive ratchet 121 is rotated and is located inside the slide box 21 at the bottom. The upper side of the drive ratchet 121 can mesh with the toothed plate 223.

[0028] During operation, the drive motor 14 is started, driving the conveyor roller 12 and the drive ratchet 121 to rotate, causing the thermoplastic elastomer tube to be conveyed forward. When the tube radius changes, the auxiliary conveyor roller 13 drives the trigger rod 131 to move, changing the valve opening between the valve seat 151 and the cone valve body 153 in the water-cooled pipe 15, and adjusting the cooling water spray flow rate. During the conveying process, the drive ratchet 121 drives the toothed plate 223 to move to the right, causing the lower cutting machine 22 to move to the right along the slide 211 and rotate the saw blade to the front of the tube. The toothed plate 223 pushes the piston push rod 224, allowing the liquid in the hydraulic channel 212 to enter the hydraulic rod 222, pushing the lower cutting machine 22 to cut the tube. Afterward, the piston push rod 224 compresses the spring in the hydraulic channel 212. When the spring force is greater than the driving force, the piston push rod 224 resets, the drive ratchet 121 rotates freely, and the hydraulic rod 222 drives the lower cutting machine 22 to reset, continuing to cut the lower section of the tube at equal intervals until all cutting is completed.

[0029] In summary, through the coordinated operation of the auxiliary conveying roller 13, trigger rod 131, and valve structure within the water-cooled pipe 15 in the conveying structure 1, the spray flow rate of cooling water can be automatically and precisely adjusted according to the real-time changes in the radius of the thermoplastic elastomer pipe of the marine equipment. When the pipe diameter increases, the opening of the conical valve orifice on the valve seat 151 increases, allowing more cooling water to enter from the input interface of the water-cooled pipe 15, flow through the water holes on the surface of the conical valve body 153 to the nozzle, and spray onto the pipe surface. This ensures rapid and uniform cooling and solidification of the pipe, avoiding uneven internal structure due to insufficient water cooling, effectively improving the mechanical properties and dimensional accuracy of the product, and reducing the defect rate. When the pipe diameter decreases, the valve orifice opening decreases, reducing water waste. In this way, the potential impact of excessive cooling on product quality is avoided. This intelligent adjustment mechanism greatly shortens the cooling time of the pipe body and significantly improves production efficiency. Through the setting of the cutting structure 2, the ratchet 121 drives the toothed plate 223 to move, thereby causing the lower cutting machine 22 to move precisely to the right along the slide 211 and be positioned at the front of the pipe body. The toothed plate 223 pushes the piston push rod 224, so that the liquid in the hydraulic channel 212 enters the hydraulic rod 222, driving the lower cutting machine 22 to complete the cutting operation. After the cutting is completed, the piston push rod 224 compresses the spring in the hydraulic channel 212 and resets under the action of the spring force, driving the lower cutting machine 22 to reset, realizing automatic circulation, which can efficiently perform equidistant cutting of the lower section of the pipe body.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Working principle: During operation, the drive motor 14 is first started, which drives the conveyor roller 12 to rotate. The drive ratchet 121 at the front shaft end of the conveyor roller 12 rotates accordingly. When the conveyor roller 12 rotates, it drives the marine equipment thermoplastic elastomer tube placed on the conveying structure 1 forward through friction. During the tube's conveying process, when the tube radius changes, the pressure exerted by the tube on the auxiliary conveyor roller 13 changes. Since the auxiliary conveyor roller 13 is movably connected to the frame 11 through a bearing seat and a spring, when the tube radius increases, the tube presses upward against the auxiliary conveyor roller 13, causing the auxiliary conveyor roller 13 to move upward, which in turn drives the trigger rod 131 to move upward; when the tube radius decreases, under the action of the spring... When the auxiliary conveyor roller 13 moves downward, the trigger rod 131 also moves downward. The movement of the trigger rod 131 affects the valve structure inside the water-cooled pipe 15. When the trigger rod 131 moves upward, it pushes up the cone valve body 153. The cone valve body 153 slides upward against the elastic force of the spring rod 152, increasing the opening of the cone valve orifice on the valve seat 151. More cooling water enters from the input interface of the water-cooled pipe 15 and flows to the nozzle through the water holes on the surface of the cone valve body 153, thereby increasing the spray flow rate on the pipe and meeting the cooling water demand when the pipe diameter increases. Conversely, when the trigger rod 131 moves downward, the cone valve body 153 slides downward under the action of the spring rod 152, reducing the valve orifice opening and decreasing the cooling water flow. To reduce the spray flow rate and avoid water waste when the pipe diameter decreases, during the rightward transfer of the marine equipment thermoplastic elastomer tube, the rotating drive ratchet 121 engages with the toothed plate 223, causing the toothed plate 223 to drive the mounting base 221 and the downward cutting machine 22 fixed thereon to move to the right along the slide 211. Then, the downward cutting machine 22 rotates and the saw blade falls into the front of the marine equipment thermoplastic elastomer inside the frame 11 to cut the marine equipment thermoplastic elastomer tube. At the same time, the moving toothed plate 223 pushes the piston rod 224, causing the piston rod 224 to compress the safety fluid inside the hydraulic fluid passage 212 into the hydraulic rod 222, and push the hydraulic rod 222. The piston rod inside 22 outputs hydraulic fluid 222, which pushes the lower cutting machine 22 to perform a complete cut on the thermoplastic elastomer tube of the marine equipment. Then, the piston push rod 224 contacts the spring inside the hydraulic fluid channel 212 and compresses the spring. When the spring force is greater than the driving force of the ratchet 121, the spring pushes the piston push rod 224 to the left to reset. The ratchet 121 will idle and draw back the safety fluid that entered the hydraulic rod 222, causing the hydraulic rod 222 to drive the lower cutting machine 22 to reset. Then, it will proceed to the equidistant cutting of the next section of the marine equipment thermoplastic elastomer tube until the cutting of the marine equipment thermoplastic elastomer tube is completed.

[0032] It should be noted that the valve structure inside the water-cooling pipe 15 can be replaced with other push-triggered valve structures.
