Description

Technical Field

[0001] This utility model relates to the field of composite pipe production technology, specifically a composite pipe production and forming device. Background Technology

[0002] Composite pipes are pipes made by combining various materials through specific processes. They integrate the advantages of different materials, such as the high strength of metals, the corrosion resistance of plastics, and the unique properties of other special materials, resulting in excellent mechanical properties, chemical stability, and heat and cold resistance. They are widely used in many fields such as building water supply and drainage, petrochemicals, gas transmission, and power and telecommunications, playing a crucial role in modern engineering construction and industrial production. They can adapt to complex and diverse operating environments and conditions, effectively ensuring the safe and stable operation of various systems. However, in the production of existing composite pipes, the raw materials are simply poured together and heated during the hot-melt mixing process. Because the raw material particles vary in size (larger particles are heavier than smaller particles), the hot-melt process can lead to uneven melting, with larger particles not fully fused or smaller particles over-fused, resulting in reduced stability of the composite pipe's performance.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention proposes a composite pipe production and molding device. When composite pipes are to be produced, raw materials are quantitatively added to the surface of a filter plate. The dual-shaft motor is then started, causing the large gear to rotate with the small gear A. The rotation of the small gear A causes the half gear to move back and forth with the rectangular frame. The reciprocating rectangular frame then moves the filter plate back and forth, thereby screening the particles on the surface of the filter plate. Since the partition plate is constantly rotating counterclockwise, the particles on the surface of the filter plate are always moving at the filter holes. Small particles of raw material pass through the filter holes and enter one set of mixing chambers. The remaining large particles, when the dual-shaft motor stops operating, move along the filter plate to the feed inlet B and finally fall into another set of mixing chambers for stirring. Afterward, the raw material particles are heated by the heating plate and stirred by the stirring rod. Finally, the arc-shaped telescopic plate is activated to contract and send the melted material into the extruder to produce composite pipes. Thus, the screening by the filter plate improves the stability of the composite pipe performance. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] To address the technical issues of how to raise [the issue], such as... Figures 1-6 As shown, the following preferred technical solutions are provided:

[0021] A composite pipe production and forming apparatus includes an extruder 1, and a processing component 2 for processing composite pipe raw materials is fixedly installed on the outer surface of the extruder 1.

[0022] Processing component 2 includes a processing box 21 fixedly mounted on the outer surface of the extruder 1, and a screening assembly 22 fixedly mounted on the upper surface of the processing box 21 for screening raw material particles.

[0023] The screening assembly 22 includes a stopping assembly 222 fixedly installed on the upper surface of the processing box 21 for blocking raw material particles. There are two sets of stopping assemblies 222, and a filter plate 221 is arranged between the two sets of stopping assemblies 222. Each set of stopping assemblies 222 has a swing assembly 224 on one side for vibrating the filter plate 221. The swing assembly 224 can vibrate and screen the particles on the surface of the filter plate 221, and the stopping assembly 222 can temporarily retain the particles on the surface of the filter plate 221, which can further improve the screening effect.

[0024] The pause assembly 222 includes a fixed plate 2221 fixedly mounted on the upper surface of the processing box 21, a dual-axis motor 2222 fixedly mounted inside the fixed plate 2221, and a drive rod 2223 located at the output end of the dual-axis motor 2222. There are two sets of drive rods 2223, one set of which is connected to the other set of fixed plates 2221. A spacer plate 2224 is sleeved on the outer surface of one set of drive rods 2223 and is located on the surface of the filter plate 221. A large gear 2225 is fixedly mounted on the outer surface of the two sets of drive rods 2223. By starting the dual-axis motor 2222, the spacer plate 2224 can be rotated at a uniform speed, so that the particles on the surface of the filter plate 221 are always located on one side of the spacer plate 2224. When the screening time is over, the operation of the dual-axis motor 2222 is stopped, so that the spacer plate 2224 is in a horizontal state, allowing the large particles of raw material to move to the other end of the filter plate 221.

[0025] A baffle 2211 is fixedly installed on the surface of the filter plate 221. The surface of the filter plate 221 has an arc groove 2212 and a filter hole 2213. The lower surface of the partition plate 2224 is in contact with the surface of the arc groove 2212. The raw material particles can be screened through the filter hole 2213. The large raw material particles can be moved to one end of the filter plate 221 by the inclined state of the filter plate 221, so that they can enter the processing box 21.

[0026] The rocking assembly 224 includes a round rod 2241 disposed on the other side of the fixed plate 2221, a pinion A2242 and a half gear 2243 fixedly mounted on the outer surface of the round rod 2241, the round rod 2241 being located below the drive rod 2223, the pinion A2242 meshing with the large gear 2225, a rectangular frame 2244 sleeved on the outer surface of the half gear 2243, a rack 2245 fixedly mounted on the inner wall surface of the rectangular frame 2244, the rack 2245 meshing with the half gear 2243, and connecting rods 2246 fixedly mounted on both sides of the rectangular frame 2244, with two sets of connecting rods. 2246 is arranged in a symmetrical, oblique mirror configuration. One set of connecting rods 2246 is fixedly connected to one side of the filter plate 221, and the other set of connecting rods 2246 is fixedly connected to one side of the baffle 2211. The rotation of the large gear 2225 drives the small gear A2242 and the half gear 2243 to rotate together. Since the half gear 2243 only has half of the teeth, when the half gear 2243 rotates, it can drive the rectangular frame 2244 to move back and forth, thereby causing the connecting rods 2246 to move back and forth with the filter plate 221. Then, in conjunction with the partition plate 2224, the particles are blocked, which can improve the screening speed of the raw material particles.

[0027] The processing box 21 has a stirring chamber on its inner wall, and there are two sets of stirring chambers. Each set of stirring chambers has a heating cavity 211 on its inner wall. A heating plate 2111 and a quartz glass 212 are fixedly installed on the inner wall of the heating cavity 211. The upper surface of the processing box 21 has an inlet B216, an inlet A215, and a rod hole 214. An inclined frame 25 is fixedly installed on the upper surface of inlet A215, and an outer frame 24 is fixedly installed on the upper surface of inlet B216. A plate groove 241 is formed on one side of the outer frame 24. One end of a filter plate 221 is fitted to the bottom of the plate groove 241. The upper surface of the inclined frame 25 is connected to the filter plate 221. The lower surfaces of the two parts are in contact with each other. The inclined frame 25 and the filter hole 2213 are on the same vertical line. The feed port A215 is connected to one set of mixing chambers, and the feed port B216 is connected to another set of mixing chambers. The motor 23 is fixedly installed on the upper surface of the processing box 21, and the arc-shaped telescopic plate 213 is fixedly installed at the bottom of the processing box 21. The small particles of raw material screened by the vibration can be introduced into the feed port A215 through the inclined frame 25, and then enter one set of mixing chambers. The large particles of raw material after screening will move to the feed port B216 and enter the other set of mixing chambers for mixing.

[0028] Two sets of rod holes 214 are provided, and each set of rod holes 214 has a rotating rod 231 inside. One end of the rotating rod 231 in one set is connected to the output end of the motor 23. A small gear B is sleeved on the outer surface of the rotating rod 231 in both sets, and a toothed chain 232 is sleeved on the outer surface of the small gear B. A stirring rod 233 is fixedly installed on the lower surface of the rotating rod 231 in both sets, and the two stirring rods 233 are located in the two stirring chambers respectively. The temperature of the two heating plates 2111 can be adjusted according to the particle size. Then, the heated material is stirred by the stirring rod 233. Finally, the material is uniformly fed into the extruder 1 by the arc-shaped telescopic plate 213, and then the material is extruded and shaped by the extruder 1.

[0029] Specifically, when producing composite pipes, raw material particles are quantitatively added to the surface of filter plate 221. Then, the dual-shaft motor 2222 is started, causing the drive rod 2223 to rotate the large gear 2225 and the small gear A2242. As the small gear A2242 rotates, the half gear 2243 will preferentially mesh with the rack 2245 at the top of the rectangular frame 2244, thereby moving the rectangular frame 2244 to one end. After the half gear 2243 rotates half a turn, it will engage with the rectangular frame. The rack 2245 at the bottom of 2244 meshes with the rectangular frame 2244, causing it to rotate to the other end. This causes the rectangular frame 2244 to reciprocate. As the rectangular frame 2244 begins to reciprocate, the filter plate 221, fixedly connected to the connecting rod 2246, also reciprocates. Because the large gear 2225 has a larger diameter than the small gear A2242, the small gear A2242 rotates faster than the large gear 2225, resulting in a faster reciprocating speed for the filter plate 221 connected to the rectangular frame 2244. The raw material particles can be screened because the filter plate 221 is tilted. The raw material particles move along the filter plate 221 to the high partition plate 2224. Since the partition plate 2224 is constantly rotating counterclockwise, the particles on the surface of the filter plate 221 are continuously impacted and pushed back, keeping the raw material particles at the filter holes 2213, thus improving the screening effect of the filter holes 2213. When the next batch of raw materials needs to be added, the operation of the dual-shaft motor 2222 is stopped, allowing the partition plate 2224 to move back to its original position. When filter plate 24 is in a horizontal position, the raw material will move along filter plate 221 to the feed inlet B216 and eventually enter a set of mixing chambers. The small particles of raw material that pass through filter holes 2213 will enter another set of mixing chambers. At this time, heating plate 2111 and motor 23 are activated to stir the raw material particles. Finally, the arc-shaped telescopic plate 213 is activated to retract, allowing the material to enter the extruder 1 to form a composite tube. Thus, the composite tube's performance stability is improved by screening through filter plate 221.
