Description

Technical Field

[0001] The present invention belongs to the technical field of cable production, and specifically relates to an extrusion device for producing special cables for ships. Background Art

[0002] With the rapid development of science and technology and the continuous improvement of automation, the automation and intelligence technologies of ships are also getting higher and higher. Since ships operate in complex and harsh environments, including the corrosion of seawater, different climate conditions, and complex electromagnetic environments, etc., special cables for intelligent devices on ships need to have a variety of special properties, such as good corrosion resistance, flame retardancy, high and low temperature resistance, electromagnetic interference resistance, etc. These special property requirements pose high demands on the production process and equipment of cables.

[0003] Publication No. CN118269323B discloses a cable plastic extruder, belonging to the technical field of cable processing; the cable plastic extruder includes: a bottom plate, an extrusion mechanism, a support frame, an installation box, a rotating plate, a material receiving tank, a discharge pipe, a lifting mechanism, an installation plate, a heating and stirring assembly, a first receiving cylinder, an extrusion block, a first lead screw, a slider, a scraping plate assembly, and a first connecting rod; the first lead screw drives the slider to move downward, so that the slider drives the scraping plate assembly to move towards the inner wall of the material receiving tank through the first connecting rod, so that the scraping plate assembly fits with the inner wall of the material receiving tank, and then the first receiving cylinder is rotated, so that the scraping plate assembly rotates on the inner wall of the material receiving tank and scrapes off the adhered plastic slurry. Reverse rotation of the first lead screw causes the first lead screw to drive the slider to move upward, so that the scraping plate assembly is separated from the inner wall of the material receiving tank, facilitating the removal of the scraping plate assembly from the material receiving tank, and at the same time, facilitating the entry of the scraping plate assembly into the material receiving tank, thereby improving the user experience of the product.

[0004] The size of the extrusion port of the above device is fixed, resulting in the same flow rate and pressure of the extruded material, while the requirements of different extrusion dies are different. When the device flow rate is greater than the required flow rate of the die, it is easy to cause material blockage and accumulation, resulting in uneven extrusion. At the same time, because the special cable material for ships contains special additives such as flame retardants and reinforcing fibers, it is necessary to reduce the discharge diameter to increase the extrusion pressure. Therefore, an extrusion device for producing special cables for ships is proposed. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The present invention facilitates the adjustment of the discharge diameter by setting the cooperation of structures such as the slide groove and the straight groove. The outer shell is rotated to expand the regular hexagonal discharge area formed between the six blocks, so that the flow rate of the passing material is within the bearing range of the extrusion die, and the flow rate is prevented from being too large and exceeding the bearing range of the die, resulting in material blockage and accumulation, thereby causing uneven extrusion. At the same time, the flow rate can be adjusted at any time according to actual conditions during the working process to prevent the extrusion speed from being too fast and exceeding the actual demand, resulting in excessive material being extruded and unable to be effectively utilized and wasted. In addition, because the special cable material for ships contains special additives such as flame retardants and reinforcing fibers, reducing the diameter of the discharge area at this time can increase the pressure when the material is extruded, so that the flame retardant is more evenly distributed in the insulation layer or the sheath layer, thereby improving the flame retardant performance of the cable. At the same time, the higher pressure can make the fibers better oriented and arranged, thereby enhancing the mechanical strength of the cable.

[0019] The present invention facilitates loading and unloading of the mounting seat by arranging the coordination of structures such as the card block and the card slot. After a batch of cables are extruded, the mounting seat can be quickly loaded, unloaded and replaced, which can reduce the downtime of the device. At the same time, when producing different types of special cables for ships, different materials or additives may be used. Rapid replacement of the mounting seat can prevent the residual materials of the previous batch from polluting the next batch of production. The detachability of the mounting seat makes it more convenient to clean and maintain it separately.

[0020] The present invention facilitates self-cleaning of the extrusion port by arranging the cooperation of structures such as the driving gear and the scraper. When the mounting seat is installed and disassembled, the four scrapers will be driven to slide with the surface of the extrusion port to scrape off the material stuck on the extrusion port, preventing the material from sticking and accumulating at the extrusion port and gradually increasing, which eventually leads to blockage of the extrusion port. This can effectively prevent the hidden danger of blockage, ensure the normal and continuous operation of the extrusion equipment, and improve production efficiency. Moreover, sticky materials attached to the extrusion port for a long time may corrode the metal parts of the extrusion port. The scraper cleans up these materials in time, which can reduce the possibility of corrosion, thereby extending the service life of the extrusion port parts and reducing the maintenance cost of the equipment.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1 to 8 shown, the present invention provides an extrusion device for the production of special cables for ships, including an adjustment mechanism 1. An installation mechanism 2 is arranged inside the adjustment mechanism 1. An extrusion mechanism 3 is arranged on the side of the adjustment mechanism 1. A cleaning mechanism 4 is arranged inside the extrusion mechanism 3;

[0032] The adjusting mechanism 1 includes an adjusting housing 101. A discharge hole 102 is provided at the center of the adjusting housing 101. Six sliding grooves 103 are evenly provided on the inner wall of the adjusting housing 101. A sliding rod 104 is slidably connected inside the sliding groove 103. A stopper 105 is fixedly connected to the sliding rod 104. Two limiting blocks 106 are fixedly connected to the side of the stopper 105. Two limiting grooves 107 are provided on the side of the stopper 105 away from the limiting block 106. A sliding plate 108 is fixedly connected to the side of the stopper 105 away from the sliding rod 104. A cavity 111 is provided inside the adjusting housing 101. A handle 109 is slidably connected inside the cavity 111. The handle 109 is elastically connected to the inner wall of the cavity 111 through a first spring 110. One end of the handle 109 penetrates through the inner wall of the cavity 111 and extends into the adjusting housing 101. An inclined block 112 is fixedly connected to the end of the handle 109 located inside the adjusting housing 101.

[0033] The outer shape of the stopper 105 is fan-shaped. The six stoppers 105 are slidably combined through the limiting blocks 106 and the limiting grooves 107 to form a cylinder, and a regular hexagon discharge area is formed at the center position of the cylinder. The end of the handle 109 away from the inclined block 112 penetrates through the inner wall of the cavity 111 and extends to the outside of the adjusting housing 101. The stopper 105 is located between the inclined block 112 and the sliding groove 103.

[0034] The installation mechanism 2 includes an installation base 201. Six straight grooves 202 are evenly provided on the installation base 201. A number of inclined grooves 203 are evenly provided on the side of the installation base 201. Four positioning holes 204 are evenly provided on the side of the installation base 201 away from the straight grooves 202. A groove 205 is provided on the side of the installation base 201 away from the straight grooves 202. Four fixing blocks 206 are fixedly connected to the side of the installation base 201 close to the positioning holes 204. A clamping groove 207 is provided on the side of each of the two fixing blocks 206 away from each other. A number of tooth grooves 208 are provided on the side of the four fixing blocks 206 close to each other.

[0035] The above scheme is adopted: by setting the cooperation of structures such as the slide groove 103 and the straight groove 202, it is convenient to adjust the discharge diameter, pull the handle 109 in the direction away from the adjustment shell 101, so that the clamping between the inclined block 112 and the inclined groove 203 is released, and the first spring 110 is squeezed, and then the adjustment shell 101 is rotated to apply stress to the slide rod 104 through the slide groove 103, and the slide rod 104 is driven by the stress to slide inside the slide groove 103, thereby driving the block 105 to slide in a straight line inside the straight groove 202 through the slide plate 108, so that the six blocks 105 are moved away from each other and the regular hexagonal discharge area formed between the six blocks 105 is expanded, so that the flow rate of the material passing through the extrusion die is The bearing range can be prevented to prevent the flow rate from being too large and exceeding the bearing range of the mold, resulting in material blockage and accumulation, which in turn causes uneven extrusion. At the same time, the flow rate can be adjusted at any time according to the actual situation during the working process to prevent the extrusion speed from being too fast and exceeding the actual demand, resulting in too much material being extruded and unable to be effectively utilized and wasted. In addition, because the special cable materials for ships contain special additives such as flame retardants and reinforcing fibers, reducing the diameter of the discharge area can increase the pressure during material extrusion, thereby making the flame retardant more evenly distributed in the insulation layer or sheath layer, thereby improving the flame retardant properties of the cable. At the same time, higher pressure can better orient the fibers and enhance the mechanical strength of the cable.

[0036] like Figures 2 to 6 As shown, the four fixing blocks 206 are staggered with the four positioning holes 204, a discharge hole 102 is provided at the center of the mounting seat 201, the groove 205 is located between the four positioning holes 204, the end of the mounting seat 201 close to the straight groove 202 is rotatably connected to the inner wall of the adjusting shell 101, the slide plate 108 is slidably connected to the straight groove 202, and the inclined block 112 is clamped to the inclined groove 203.

[0037] The extrusion mechanism 3 includes a shell 301, four positioning rods 302 are fixedly connected to the side of the shell 301, a convex ring 303 is fixedly connected to the side of the shell 301 close to the positioning rod 302, four fixed grooves 304 are evenly opened on the side of the shell 301 close to the positioning rod 302, and the internal sliding connection of the two fixed grooves 304 is provided with a card block 305, wherein the two card blocks 305 are fixedly connected to the side away from each other with a push block 306, and the push block 306 is elastically connected to the inner wall of the shell 301 through a second spring 307, a feed port 308 is provided on the top of the shell 301, an extrusion chamber 309 is provided inside the shell 301, a motor 310 is fixedly connected to the side of the shell 301 away from the positioning rod 302, a screw 311 is rotatably connected to the motor 310, and an extrusion port 312 is opened on the side of the extrusion chamber 309 close to the positioning rod 302.

[0038] The pushing block 306 extends through the inner wall of the housing 301 to the side of the housing 301. The two pushing blocks 306 are respectively located on the side far away from each other of the two fixing grooves 304. The screw 311 extends through the side of the housing 301 to the inside of the extrusion cavity 309. The size of the extrusion port 312 is smaller than the size of the convex ring 303. The four fixing grooves 304 and the four positioning rods 302 are staggeredly distributed. The convex ring 303 is located between the four fixing grooves 304. The clamping block 305 is provided with an inclined surface. The size of the extrusion port 312 is adapted to the size of the discharge hole 102. The convex ring 303 is clamped with the groove 205. The positioning rod 302 is clamped with the positioning hole 204. The fixing block 206 is clamped with the fixing groove 304. The clamping block 305 is clamped with the clamping groove 207. The pushing blocks 306 are located on the upper and lower sides of the mounting seat 201.

[0039] Adopting the above scheme: Through the cooperation of structures such as the clamping block 305 and the clamping groove 207, the loading and unloading of the mounting seat 201 is facilitated. When the extrusion of a batch of cables is completed, the two pushing blocks 306 can be pushed respectively in the direction away from the convex ring 303 to release the clamping connection between the clamping block 305 and the clamping groove 207, and then the mounting seat 201 is removed from the side of the housing 301. Subsequently, the positioning hole 204 on another mounting seat 201 that has been cleaned is aligned with the positioning rod 302 on the housing 301, and at the same time, the fixing block 206 provided with the clamping groove 207 is aligned with the fixing groove 304 in which the clamping block 305 is slidably connected inside. At this time, the convex ring 303 is aligned with the groove 205, and then the mounting seat 201 is moved in the direction close to the housing 301, so that the fixing block 206 presses the inclined surface of the clamping block 305. By pressing the inclined surface, the clamping block 305 is moved out of the fixing groove 304 and presses the second spring 307. When the fixing block 206 is clamped with the fixing groove 304, the clamping block 305 is aligned with the clamping groove 207. At this time, the clamping block 305 will be clamped with the clamping groove 207 under the action of the elastic force of the second spring 307, and the positioning rod 302 is clamped with the positioning hole 204, and the convex ring 303 is clamped with the groove 205, quickly completing the loading, unloading and replacement of the mounting seat 201, reducing the downtime of the device. At the same time, when producing different types of ship special cables, different materials or additives may be used. Quickly replacing the mounting seat 201 can prevent the residues of the previous batch of materials from polluting the production of the next batch, and the detachable nature of the mounting seat 201 makes it more convenient to clean and maintain it separately.

[0040] Such as Figures 3 to 5As shown in the figure, the cleaning mechanism 4 includes a driving gear 401. Conical gears 402 are fixedly connected to the sides of the driving gear 401 and the driven gear 403. The two conical gears 402 mesh with each other. The bottom of the driven gear 403 meshes with the side of a toothed ring 404. Four scraping plates 405 are fixedly connected to the inner wall of the toothed ring 404. There are four driving gears 401 and four driven gears 403. The driving gears 401 and the driven gears 403 are rotatably connected to the inner wall of the housing 301. The driving gear 401 penetrates through the inner wall of the housing 301 and extends into the fixing groove 304. The part of the driving gear 401 located in the fixing groove 304 meshes with the tooth groove 208. The toothed ring 404 is rotatably connected to the inner wall of the housing 301. The scraping plates 405 penetrate through the inner wall of the housing 301 and extend into the extrusion port 312. The surface of the scraping plates 405 fits against the inner wall of the extrusion port 312.

[0041] With the above solution: Through the cooperation of structures such as the driving gear 401 and the scraping plate 405, it is convenient to self-clean the extrusion port 312. When installing and disassembling the mounting seat 201, the tooth groove 208 on the fixing block 206 will drive the driving gear 401 to rotate one circle. The rotation of the driving gear 401 will drive the driven gear 403 to rotate one circle through the conical gear 402. The rotation of the driven gear 403 will drive the toothed ring 404 to rotate 90°. The rotation of the toothed ring 404 by 90° will drive the four scraping plates 405 to slide on the surface of the extrusion port 312, scraping off the materials adhered to the extrusion port 312, preventing the materials from adhering and accumulating at the extrusion port 312 and gradually increasing, and finally causing the extrusion port to be blocked. This can effectively prevent this kind of blockage hidden danger, ensure the normal and continuous operation of the extrusion equipment, improve the production efficiency, and the adhered materials may corrode the metal parts of the extrusion port 312 if they adhere to the extrusion port 312 for a long time. The scraping plates can clean up these materials in time, reducing the possibility of corrosion, thereby extending the service life of the components of the extrusion port 312 and reducing the maintenance cost of the equipment.

[0042] The working principle and use process of the present invention are as follows: first, a suitable extrusion die is selected according to the size of the core wire, and the flow rate through the discharge hole 102 is adjusted according to the size of the extrusion die, that is, the handle 109 is pulled in the direction away from the adjustment housing 101, so that the oblique block 112 and the inclined groove 203 are released from the clamping connection, and the first spring 110 is squeezed, and then the adjustment housing 101 is rotated to apply stress to the slide bar 104 through the slide groove 103, and the slide bar 104 is driven by the stress to slide inside the slide groove 103, thereby driving the block 105 to slide along a straight line inside the straight groove 202 through the slide plate 108, so that the six blocks 105 are away from each other and the regular hexagonal discharge area formed between the six blocks 105 is expanded, so that the flow rate of the material passing through is within the bearing range of the extrusion die, and then the handle 109 is released to make the oblique block 112 clamped with the inclined groove 203 under the action of the elastic force of the first spring 110, and the die is fixed on the side of the adjustment housing 101 away from the discharge hole 102;

[0043] After a batch of cables are extruded, the two push blocks 306 can be pushed away from the convex ring 303 to release the engagement between the clamping block 305 and the clamping groove 207, and then the mounting seat 201 can be removed from the side of the housing 301. During this process, the fixing block 206 drives the driving gear 401 to rotate one circle through the tooth groove 208. The rotation of the driving gear 401 drives the driven gear 403 to rotate one circle through the bevel gear 402. The rotation of the driven gear 403 drives the gear ring 404 to rotate 90°. The rotation of the gear ring 404 by 90° drives the four scrapers 405 to slide with the surface of the extrusion port 312 to scrape off the material stuck on the extrusion port 312.

[0044] After the mounting seat 201 is disassembled, the positioning hole 204 on the other mounting seat 201 that has been cleaned can be aligned with the positioning rod 302 on the shell 301, and the fixing block 206 with the card slot 207 can be aligned with the fixing groove 304 with the card block 305 slidably connected inside. At this time, the convex ring 303 is aligned with the groove 205, and then the mounting seat 201 is moved in the direction close to the shell 301, so that the fixing block 206 squeezes the inclined surface of the card block 305, and the card block 305 is moved out of the fixing groove 304 and The second spring 307 is squeezed, and when the fixed block 206 is engaged with the fixed groove 304, the block 305 is aligned with the groove 207. At this time, the block 305 is engaged with the groove 207 under the action of the elastic force of the second spring 307, and the positioning rod 302 is engaged with the positioning hole 204, and the convex ring 303 is engaged with the groove 205. During this process, the tooth groove 208 on the fixed block 206 is engaged with the driving gear 401, and as the fixed block 206 moves, the scraper 405 is driven to rotate 90° in the opposite direction and reset, and then the next batch of work can be carried out.
