Description
Technical Field
[0001] The invention relates to the technical field of unidirectional belt production equipment, in particular to a unidirectional belt production line with a highly integrated mold. Background Art
[0002] Continuous fiber reinforced thermoplastic unidirectional tape is a sheet material made of parallel unidirectional continuous fibers through a melt impregnation process and then impregnated with molten thermoplastic resin (PE, PP, PA, etc.). The performance of continuous fiber reinforced thermoplastic composites is very excellent. The longer the fiber length, the better the mechanical properties. Its specific strength can be more than 10 times that of ordinary steel. The higher the specific strength, the lighter the material used to achieve the corresponding strength. Therefore, continuous fiber reinforced thermoplastic composites can truly replace steel with plastic and achieve lightweight applications.
[0003] Among them, during the production process of unidirectional tape, the fiber yarn needs to be impregnated with resin. In order to maintain good wettability, a larger extrusion force is often used to accelerate the resin penetration process. Although a larger pressure helps to accelerate resin penetration, high pressure may cause resin accumulation in some areas and insufficient in other areas, thus affecting the quality of the product. Summary of the invention
[0004] In order to solve the above technical problems, the present invention provides a unidirectional tape production line with a highly integrated mold, including an extruder, a yarn rack, an integrated mold section, a cooling and leveling section, a traction machine, and a winder.

[0006] The cooling mechanism includes two sliding grooves provided on the inner wall of the extrusion die, nine partition plates are fixedly connected to the inner walls of the two sliding grooves, and nine sliding plates are slidably connected to the inner walls of the two sliding grooves;
[0007] The laminating mechanism comprises two connecting plates slidably connected to the side walls of the extrusion die, two oil pipes are fixedly connected to the inner wall of the extrusion die, spring piston rods are fixedly connected to the inner walls of the two oil pipes, and hydraulic oil is provided on the inner walls of the two oil pipes.
[0008] Preferably, the extrusion mechanism further comprises an extruder arranged at the side wall of the frame, a connecting pipe is fixedly connected to the side wall of the extruder, the side walls of the two extrusion heads are through-connected to the side walls of the connecting pipe, and the inner wall of the extrusion die is slidably connected to the fiber yarn;
[0009] Among them, a fixed frame is provided at the side wall of the frame, and a motor is fixedly connected to the side wall of the fixed frame. Two large cooling rollers are rotatably connected to the side wall of the fixed frame. The output end of the motor at the side wall is fixedly connected to the side wall of the large cooling roller located at the top. The staff passes the fiber yarn through the gap in the extrusion die until the fiber yarn passes between the two large cooling rollers, and then starts the motor to drive the large cooling roller to rotate. The friction between the large cooling roller and the fiber yarn drives the fiber yarn to move. At the same time, the extruder is started to extrude the resin, and the resin is transported to the extrusion head through the connecting pipe. The fiber yarn is poured through the upper and lower extrusion heads to allow the resin to be soaked in the fiber yarn. The soaked fiber yarn will be shaped by the extrusion die to form the shape of a unidirectional belt.
[0010] Preferably, the extrusion mechanism further comprises eight small cooling rollers rotatably connected to the inner wall of the fixed frame, the front and back sides of the extrusion die are fixedly connected to connecting blocks, the side wall of the frame is fixedly connected to two concave and convex blocks, and the inner wall of the extrusion die is movably connected to two extrusion rollers;
[0011] Among them, the side walls of the two extrusion rollers are fixedly connected with fixed rods, and the outer walls of the two fixed rods are slidably connected to the inner wall of the connecting block located on the front. The fiber yarn is discharged from the top and bottom at the same time to improve the wettability of the unidirectional tape. At this time, the unidirectional tape will contact the extrusion roller, allowing the extrusion roller to extrude the unidirectional tape. When the unidirectional tape moves, the extrusion roller rotates through friction, driving the fixed rod to rotate.
[0012] Preferably, the extrusion mechanism further comprises an L-shaped rod fixedly connected to the side wall of the fixed rod, the side walls of the two L-shaped rods are slidably connected to the side walls of the concave and convex blocks, and the inner walls of the two extrusion rollers are rotatably connected to reciprocating rollers;
[0013] The L-shaped rod is moved from the recessed position of the concave-convex block to the raised position, and the L-shaped rod is pushed to move laterally, driving the extrusion roller to move laterally, so that the spring reset rod accumulates rebound force. When the extrusion roller moves laterally, it drives the reciprocating roller to move, so that the reciprocating roller moves on the shaped unidirectional belt. When the L-shaped rod rotates to the recessed position of the concave-convex block again, the rebound force of the spring reset rod is released, pushing the extrusion roller to return to its position, driving the reciprocating roller to return to its position, and so on, so that the reciprocating roller rubs the unidirectional belt back and forth, promotes the uniform distribution of resin between the fiber yarns, reduces the phenomenon of resin agglomeration, avoids the phenomenon of excessive or insufficient local resin, and allows the resin to form a uniform coating on the surface of the fiber yarn, thereby improving the wettability and ensuring a good combination between the fiber yarn and the resin.
[0014] Preferably, the cooling mechanism also includes a sliding rod fixedly connected to the inner wall of the sliding plate, and the outer walls of the two sliding rods are rotatably connected to the outer wall of the fixed rod. The outer walls of the two sliding rods are slidably connected to the inner wall of the extrusion mold. The force of the movement of the fixed rod will drive the sliding rod to move when the fixed rod moves laterally, thereby moving the sliding plate. Since the sliding groove is divided into multiple sealed spaces by the partition plate, the gas in the sliding groove will be squeezed when the sliding plate moves.
[0015] Preferably, the cooling mechanism also includes a blocking plate fixedly connected to the side wall of the sliding plate, nine movable grooves are opened on the inner walls of the two extrusion rollers, and the inner walls of the nine movable grooves are slidably connected with blocking rings, and the inner walls of the nine blocking rings are fixedly connected to the outer wall of the spring return rod. At this time, the squeezed gas will be blocked by the blocking plate, allowing the gas to generate high pressure. When the sliding plate moves, it will also drive the blocking plate to move. After moving a certain distance, the blocking plate will be separated from the air outlet, allowing the high-pressure gas to spray toward the reciprocating roller. At the same time, when the extrusion roller moves laterally, since the blocking ring is in a stationary state, the blocking ring will squeeze the gas in the movable groove and spray it toward the reciprocating roller. The reciprocating roller is sprayed with air from both inside and outside at the same time, thereby accelerating the cooling of the reciprocating roller.
[0016] Preferably, the fitting mechanism further comprises a push rod slidably connected to the inner wall of the oil delivery pipe, two connecting rods 1 are rotatably connected to the side walls of the two connecting plates, four connecting frames are slidably connected to the inner wall of the extrusion die, and the side walls of the four connecting frames are rotatably connected to the inner wall of the connecting rod 1;
[0017] Among them, two extrusion plates are slidably connected to the inner wall of the extrusion die, and the side walls of the two extrusion plates are fixedly connected to the side walls of the connecting frame. By utilizing the force of the sliding plate moving, when the sliding plate moves laterally, the sliding plate will contact the push rod to push the push rod to move. When the push rod moves, it will squeeze the hydraulic oil in the oil pipe. The squeezed hydraulic oil will push the spring piston rod to move, and the spring piston rod will push the connecting plate away from the extrusion die.
[0018] Preferably, the cooling mechanism further comprises two connecting rods 2 rotatably connected to the side wall of the extrusion plate, two push plates 1 are slidably connected to the inner wall of the extrusion die, the side walls of the two push plates 1 are rotatably connected to the inner wall of the connecting rod 2, two telescopic rods are fixedly connected to the inner wall of the extrusion die, and the side walls of the two telescopic rods are fixedly connected to the side wall of the push plate 1;
[0019] Among them, a pushing plate 2 is provided at the side walls of the two pushing plates 1, and four spring extrusion rods are fixedly connected to the side walls of the two pushing plates 2. The outer walls of the eight spring extrusion rods are slidably connected to the inner wall of the pushing plate 1. By utilizing the force of the movement of the extrusion plate, when the extrusion plate approaches the one-way belt, it will drive the connecting rod 2 to move, so that the connecting rod 2 rotates, and the connecting rod 2 is folded toward the direction of the one-way belt, pushing the pushing plate 1 to approach the one-way belt, pulling the telescopic rod to extend, and when the pushing plate 1 moves, it will drive the pushing plate 2 to move and contact the one-way belt. After the pushing plate 2 contacts the one-way belt, the pushing plate 1 continues to move, and it will squeeze the spring extrusion rod, allowing the spring extrusion rod to accumulate rebound force.
[0020] The present invention has the following beneficial effects:
[0021] (1) When the present invention is used, a worker passes the fiber yarn through the gap in the extrusion die until the fiber yarn passes through between the two large cooling rollers, and then starts the motor to drive the large cooling roller to rotate. The friction between the large cooling roller and the fiber yarn drives the fiber yarn to move. At the same time, the extruder is started to extrude the resin, and the resin is transported to the extrusion head through the connecting pipe. The fiber yarn is poured with material through the upper and lower extrusion heads to allow the resin to soak on the fiber yarn. The soaked fiber yarn is shaped by the extrusion die to form the shape of a unidirectional tape. The simultaneous discharge of the fiber yarn from the top and bottom improves the wettability of the unidirectional tape. At this time, the unidirectional tape contacts the extrusion roller, allowing the extrusion roller to extrude the unidirectional tape. When the unidirectional tape moves, the extrusion roller is rotated by friction, driving the fixed rod to rotate, allowing the L-shaped rod to rotate around the extrusion roller. The cylinder rotates at the center of the concave-convex block and slides on the side wall of the concave-convex block. When the L-shaped rod moves from the concave position of the concave-convex block to the convex position, it will push the L-shaped rod to move laterally, drive the extrusion roller to move laterally, and allow the spring return rod to accumulate rebound force. When the extrusion roller moves laterally, it will drive the reciprocating roller to move, and let the reciprocating roller move on the shaped unidirectional belt. When the L-shaped rod rotates to the concave position of the concave-convex block again, the rebound force of the spring return rod will be released, pushing the extrusion roller back to its position, and driving the reciprocating roller back to its position. This reciprocating process makes the reciprocating roller rub the unidirectional belt back and forth, which promotes the uniform distribution of resin between fiber yarns, reduces the phenomenon of resin agglomeration, avoids the phenomenon of excessive or insufficient local resin, and allows the resin to form a uniform coating on the surface of the fiber yarn, thereby improving the wettability and ensuring a good combination between the fiber yarn and the resin.
[0022] (2) The present invention utilizes the force of the movement of the fixed rod. When the fixed rod moves laterally, it will also drive the sliding rod to move, so that the sliding plate moves. Since the sliding groove is divided into a plurality of sealed spaces by the spacer plate, when the sliding plate moves, it will squeeze the gas in the sliding groove. At this time, the squeezed gas will be blocked by the blocking plate, causing the gas to generate high pressure. Since the movement of the sliding plate will also drive the blocking plate to move, after moving a certain distance, the blocking plate will be separated from the air outlet, allowing the high-pressure gas to be ejected toward the reciprocating roller. At the same time, when the extrusion roller moves laterally, since the blocking ring is in a stationary state, the blocking ring will squeeze the gas in the moving groove and eject it toward the reciprocating roller. By simultaneously ejecting air from the inside and outside to the reciprocating roller, the cooling of the reciprocating roller is accelerated, and additional friction is avoided when the reciprocating roller rubs the one-way belt, which causes the temperature of the reciprocating roller to be too high, thereby maintaining a good rubbing effect.
[0023] (3) The present invention utilizes the force of the sliding plate when the sliding plate moves laterally, and the sliding plate will contact the pushing rod to push the pushing rod to move. When the pushing rod moves, it will squeeze the hydraulic oil in the oil pipe. The squeezed hydraulic oil will push the spring piston rod to move, and the spring piston rod will push the connecting plate away from the extrusion die. When the connecting plate moves, it will cause the connecting rod to rotate and fold, driving the connecting frame to move toward the direction of the one-way belt. When the connecting frame moves, it will also drive the extrusion plate to move and contact the one-way belt to extrude the one-way belt. When the extrusion roller moves laterally, the extrusion plate will extrude the one-way belt, so that the extrusion plate can gradually increase the extrusion force following the rubbing amplitude of the reciprocating roller, thereby preventing the one-way belt from elastically deforming when the reciprocating roller rubs the one-way belt, thereby ensuring the width stability of the one-way belt during production.
[0024] (4) The present invention utilizes the force of the movement of the extrusion plate. When the extrusion plate approaches the one-way belt, it will drive the second connecting rod to move, allowing the second connecting rod to rotate and fold toward the direction of the one-way belt, pushing the push plate one to approach the one-way belt, pulling the telescopic rod to extend, and when the push plate one moves, it will drive the push plate two to move and contact the one-way belt. After the push plate two contacts the one-way belt, the push plate one continues to move, and it will squeeze the spring extrusion rod, allowing the spring extrusion rod to accumulate rebound force. As the extrusion pressure of the extrusion plate on both sides of the one-way belt increases, the downward amplitude of the push plate one will also increase, thereby increasing the extrusion pressure on the spring extrusion rod, and increasing the extrusion pressure on the surface of the one-way belt by the push plate two, thereby ensuring the thickness of the one-way belt and preventing the two sides of the one-way belt from being affected by the extrusion pressure, which may cause the thickness of the one-way belt to change, thereby ensuring the uniformity of the thickness of the one-way belt during production.

[0043] Among them, a fixing frame 107 is provided at the side wall of the frame 101, and a motor 108 is fixedly connected to the side wall of the fixing frame 107. Two large cooling rollers 109 are rotatably connected to the side wall of the fixing frame 107. The output end of the motor 108 at the side wall is fixedly connected to the side wall of the large cooling roller 109 located at the top. The staff passes the fiber yarn 106 through the gap in the extrusion die 102 until the fiber yarn 106 passes between the two large cooling rollers 109, and then starts the motor 108 to drive the large cooling roller 109 to rotate. The friction between the large cooling roller 109 and the fiber yarn 106 drives the fiber yarn 106 to move. At the same time, the extruder 104 is started to extrude the resin, and the resin is transported to the extrusion head 103 through the connecting pipe 105.

[0048] For example 2, please refer to Figure 5-Figure 8 The present invention is a unidirectional belt production line with a highly integrated mold. On the basis of Example 1, the cooling mechanism 2 also includes a sliding rod 204 fixedly connected to the inner wall of the sliding plate 203. The outer walls of the two sliding rods 204 are rotatably connected to the outer wall of the fixed rod 114. The outer walls of the two sliding rods 204 are slidably connected to the inner wall of the extrusion mold 102.

When the sliding plate 203 moves, it will also drive the blocking plate 205 to move. After moving a certain distance, the blocking plate 205 will be separated from the air outlet, allowing the high-pressure gas to be ejected toward the reciprocating roller 116. At the same time, when the extrusion roller 113 moves laterally, since the blocking ring 206 is in a stationary state, the blocking ring 206 will squeeze the gas in the movable groove 207 and eject it toward the reciprocating roller 116. By simultaneously ejecting air from the inside and outside to the reciprocating roller 116, the cooling of the reciprocating roller 116 is accelerated.

By utilizing the force of the movement of the sliding plate 203, when the sliding plate 203 moves laterally, the sliding plate 203 will contact the pushing rod 304, pushing the pushing rod 304 to move. When the pushing rod 304 moves, it will squeeze the hydraulic oil in the oil pipe 302. The squeezed hydraulic oil will push the spring piston rod 303 to move, and the spring piston rod 303 will push the connecting plate 301 away from the extrusion die 102.
[0052] The cooling mechanism 2 also includes two connecting rods 308 rotatably connected to the side wall of the extrusion plate 307, two push plates 309 are slidably connected to the inner wall of the extrusion die 102, and the side walls of the two push plates 309 are rotatably connected to the inner wall of the connecting rod 308, and two telescopic rods 311 are fixedly connected to the inner wall of the extrusion die 102, and the side walls of the two telescopic rods 311 are fixedly connected to the side walls of the push plates 309;
[0053] Among them, pushing plates 2 310 are provided at the side walls of the two pushing plates 1 309, and four spring extrusion rods 312 are fixedly connected to the side walls of the two pushing plates 2 310. The outer walls of the eight spring extrusion rods 312 are slidably connected to the inner wall of the pushing plate 1 309. By utilizing the force of the movement of the extrusion plate 307, when the extrusion plate 307 is close to the one-way belt, it will drive the second connecting rod 308 to move, so that the second connecting rod 308 is rotated, so that the second connecting rod 308 is folded toward the direction of the one-way belt, pushing the pushing plate 1 309 to approach the one-way belt, pulling the telescopic rod 311 to extend, and when the pushing plate 1 309 moves, it will drive the pushing plate 2 310 to move and contact the one-way belt. After the pushing plate 2 310 contacts the one-way belt, the pushing plate 1 309 continues to move, and it will squeeze the spring extrusion rod 312, so that the spring extrusion rod 312 accumulates rebound force.
[0054] There is no limitation on the number of the above components, and relevant technicians in the field can freely set them according to actual needs, as long as the above components are installed at the connection positions of the corresponding components.
[0055] A specific application of this embodiment is as follows: when the present invention is used, the staff passes the fiber yarn 106 through the gap in the extrusion die 102 until the fiber yarn 106 passes between the two large cooling rollers 109, and then starts the motor 108 to drive the large cooling roller 109 to rotate, and the friction between the large cooling roller 109 and the fiber yarn 106 drives the fiber yarn 106 to move, and at the same time starts the extruder 104 to extrude the resin, and the resin is transported to the extrusion head 103 through the connecting pipe 105, and the fiber yarn 106 is poured through the upper and lower extrusion heads 103 to allow the resin to be infiltrated on the fiber yarn 106. The infiltrated fiber yarn 106 will be shaped by the extrusion die 102 to form the shape of a unidirectional tape, and the simultaneous discharge of the upper and lower parts of the fiber yarn 106 improves the wettability of the unidirectional tape. At this time, the unidirectional tape will contact the extrusion roller 113, allowing the extrusion roller 113 to extrude the unidirectional tape. When the unidirectional tape moves, the extrusion roller 113 is rotated by the friction force, driving the fixed rod 114 to rotate, so that The L-shaped rod 115 rotates around the center of the squeezing roller 113 and slides on the side wall of the concave-convex block 112. When the L-shaped rod 115 moves from the concave position of the concave-convex block 112 to the convex position, it pushes the L-shaped rod 115 to move laterally, driving the squeezing roller 113 to move laterally, allowing the spring return rod 117 to accumulate resilience. When the squeezing roller 113 moves laterally, it drives the reciprocating roller 116 to move, allowing the reciprocating roller 116 to move on the shaped unidirectional belt. When the L-shaped rod 115 rotates again, the reciprocating roller 116 moves on the unidirectional belt. When the convex block 112 moves to the concave position, the resilience of the spring return rod 117 is released, pushing the extrusion roller 113 back to its original position, driving the reciprocating roller 116 back to its original position, and so on, so that the reciprocating roller 116 rubs the unidirectional belt back and forth, promoting the uniform distribution of the resin between the fiber yarns 106, reducing the phenomenon of resin agglomeration, avoiding the phenomenon of excessive or insufficient local resin, and allowing the resin to form a uniform coating on the surface of the fiber yarn 106, thereby improving the wettability and ensuring a good combination between the fiber yarn 106 and the resin;
[0056] Secondly, when the fixed rod 114 moves horizontally, it also drives the sliding rod 204 to move, so that the sliding plate 203 moves. Since the sliding groove 201 is divided into a plurality of sealed spaces by the partition plate 202, when the sliding plate 203 moves, it squeezes the gas in the sliding groove 201. At this time, the squeezed gas will be blocked by the blocking plate 205, so that the gas generates high pressure. When the sliding plate 203 moves, it also drives the blocking plate 205 to move. After moving a certain distance, the blocking plate 205 will be separated from the air outlet. The high-pressure gas is ejected toward the reciprocating roller 116. Meanwhile, when the extrusion roller 113 moves laterally, since the blocking ring 206 is in a stationary state, the blocking ring 206 will squeeze the gas in the moving groove 207 and eject it toward the reciprocating roller 116. By simultaneously ejecting gas from the inside and outside to the reciprocating roller 116, the cooling of the reciprocating roller 116 is accelerated, and the reciprocating roller 116 is prevented from generating additional friction when the reciprocating roller 116 rubs the one-way belt, causing the temperature of the reciprocating roller 116 to be too high, thereby maintaining a good rubbing effect.
[0057] Secondly, when the sliding plate 203 moves laterally, the sliding plate 203 will contact the pushing rod 304, pushing the pushing rod 304 to move. When the pushing rod 304 moves, the hydraulic oil in the oil pipe 302 will be squeezed. The squeezed hydraulic oil will push the spring piston rod 303 to move, and the spring piston rod 303 will push the connecting plate 301 away from the extrusion die 102. When the connecting plate 301 moves, the connecting rod 305 will rotate and fold, driving the connecting frame 306 to move in the direction of the one-way belt. When the connecting frame 306 moves, it will also drive the squeezing plate 307 to move and contact the one-way belt to squeeze the one-way belt. Because when the extrusion roller 113 moves laterally, the squeezing plate 307 will squeeze the one-way belt, so that the squeezing plate 307 can gradually increase the squeezing force following the rubbing amplitude of the reciprocating roller 116, to prevent the one-way belt from elastically deforming when the reciprocating roller 116 rubs the one-way belt, thereby ensuring the stability of the width of the one-way belt during production.
[0058] Secondly, when the extrusion plate 307 is close to the one-way belt, it will drive the second connecting rod 308 to move, so that the second connecting rod 308 rotates and folds towards the direction of the one-way belt, pushing the pushing plate 1 309 to approach the one-way belt, pulling the telescopic rod 311 to extend, and when the pushing plate 1 309 moves, it will drive the pushing plate 2 310 to move and contact the one-way belt. After the pushing plate 2 310 contacts the one-way belt, the pushing plate 1 309 continues to move, and it will squeeze the spring extrusion rod 312, allowing the spring extrusion rod 312 to accumulate resilience. As the extrusion force of the extrusion plate 307 on both sides of the one-way belt increases, the downward range of the pushing plate 1 309 will also increase, thereby increasing the extrusion force on the spring extrusion rod 312, and increasing the extrusion force on the surface of the one-way belt by the pushing plate 2 310, thereby ensuring the thickness of the one-way belt, preventing the two sides of the one-way belt from being affected by the extrusion force, which may cause the thickness of the one-way belt to change, and ensuring the uniformity of the thickness of the one-way belt during production.
