Description

Technical Field

[0001] This utility model relates to the technical field of glass fiber processing, specifically a glass fiber screw shearing machine to prevent fiber breakage. Background Technology

[0002] Fiberglass screw shears play a crucial role in fields such as polymer composites, building materials, and aerospace. In polymer composite manufacturing, the screw's shearing and extrusion functions thoroughly mix and mold glass fiber and resin, resulting in products that combine high strength and lightweight properties, such as automotive parts and sporting goods. In the building materials industry, they can manufacture fiberglass reinforced plastic pipes and sheets, meeting engineering requirements for corrosion resistance and high toughness. In the aerospace field, they are used to produce aircraft structural components, where the quality and performance requirements for the products are extremely stringent.

[0003] Existing fiberglass screw shearing machines suffer from insufficient fiber shearing, fiber leakage from the die, easy breakage of slivers, unstable side feeding, and frequent feeding difficulties due to moisture escaping from the side feeder, resulting in low production capacity. Utility Model Content

[0004] The purpose of this invention is to provide a glass fiber screw shearing machine that prevents fiber breakage, thereby solving the problems mentioned in the background art of existing glass fiber screw shearing machines, such as insufficient glass fiber shearing, fiber leakage from the die, easy fiber breakage, unstable side feeding, moisture leakage from the side feed causing frequent feeding difficulties, and low production capacity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glass fiber screw shearing machine to prevent fiber breakage, comprising a machine body, a feed inlet at the top of the machine body, a motor mounted on the rear side of the machine body, a first gear connected to the output end of the motor, a second gear meshing with the outer side of the first gear, both the first gear and the second gear being rotatably connected to the rear side of the machine body, a shearing screw connected to the ends of both the first gear and the second gear, the shearing screw being rotatably connected to the machine body, a discharge port equally spaced on the front side of the machine body, and a water tank integrally mounted on the front side of the machine body.

[0006] A flame retardant feeding hopper is connected through the right side of the machine body. A fixing frame is fixed to the rear side of the second gear corresponding to the shearing screw. The fixing frame and the contact frame are pressed and abutted. The contact frame is installed on the rear side of the machine body.

[0007] The front side of the machine body is rotatably connected to a jet pipe, which is connected to an air pump via a connecting pipe. The air pump is installed on the top front side of the machine body.

[0008] Furthermore, the rear end of the shearing screw corresponding to the second gear and the middle part of the second gear are configured as a rectangular structure. A spring is installed between the shearing screw and the rear side of the machine body. The fixing frame on the rear side of the shearing screw is configured as radial, and a hemisphere is installed at each end of the fixing frame.

[0009] Furthermore, after the fixed frame rotates, its end presses against the contact frame. The contact frame is configured with an "L" shape. A protrusion is fixed on the opposite surface of the contact frame and the fixed frame. After the protrusion contacts the hemisphere, it pushes the shear screw to generate displacement.

[0010] Furthermore, the two shearing screws will also make erroneous movements while rotating relative to each other. The output end of the shearing screw is connected to the space where the discharge port is located. The glass fiber output from the discharge port is cooled by soaking in water tank before being output.

[0011] Furthermore, the output end of the motor drives the cam to rotate synchronously through a sprocket mechanism, and the cam is rotatably connected to the outside of the left side of the machine body.

[0012] Furthermore, the front end of the cam abuts against the rack, and a limit block is symmetrically fixed to the rear side of the rack. The limit block is slidably connected to the transverse groove by a reset spring, and the transverse groove is correspondingly opened on the front side of the machine body.

[0013] Furthermore, a toothed ring is engaged with the lower part of the rack, and the toothed ring is fixed to the outside of the rotating shaft of the jet pipe. The jet pipe forms a left-right swinging blowing structure through the rack and the toothed ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This fiberglass screw shearing machine, designed to prevent fiber breakage, maintains sufficient shearing force through the screw during operation. The screw shearing, combined with relative sliding, ensures thorough mixing of the fiber and additives before extrusion and conveying. Distributed discharge ports reduce fiber leakage and breakage issues at the die opening. The interconnected side feed hoppers significantly reduce moisture leakage from the side feed, resolving feeding difficulties and allowing for timely increases in flame retardant dosage. The output fiberglass undergoes oscillating airflow as it passes through a water tank, accelerating cooling and forming.

[0016] 1. Furthermore, the materials required for glass fiber processing are fed into the feed port at the top of the machine body. The flame retardant is placed in the feed trough on the right side, so that flame retardant components can be added to the glass fiber to improve its performance. The storage capacity of the feed trough is two-thirds of the storage volume. After the motor is started, the motor drives the first gear to rotate, and the first gear drives the second gear to rotate synchronously, so that the shearing screw inside the machine body runs, thereby shearing and mixing the glass fiber and other materials. Then, it is extruded from the discharge port on the front side of the machine body. After passing through the water tank, the output glass fiber can be cooled and shaped.

[0017] 2. Furthermore, when the first gear and the second gear drive the two shearing screws to rotate, the end of the fixed frame on the rear side of the shearing screw on the first gear will intermittently press and abut against the contact frame, thereby pushing the shearing screw to rotate while also moving relative to the contact frame, compressing the spring. When the end of the fixed frame is misaligned with the contact frame, the spring will drive the shearing screw to move back to its original position. This process repeats, thereby increasing the shearing and mixing strength of the glass fiber and gas material, making the shearing and mixing more thorough and better integrated, and avoiding fiber overflow and breakage during discharge.

[0018] 3. Furthermore, the electric output end will drive the coating to rotate synchronously through the sprocket mechanism. After the cam rotates, it will push the rack to slide horizontally. When the rack slides, the limit block will move in the transverse groove, thereby compressing the return spring. When the cam rotates to the shortest position, the return spring will push the limit block to reset, thereby driving the rack to move back, so that the rack moves horizontally back and forth. After the rack moves, it drives the jet pipe to swing synchronously through the gear ring, thereby improving the air cooling effect for glass fiber cooling and forming. Attached Figure Description

[0026] 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.

[0027] Example 1: Please refer to Figures 1-3 The present invention provides the following technical solution: a glass fiber screw shearing machine for preventing fiber breakage, comprising a machine body 1, a feed inlet 2 at the top of the machine body 1, a feeding hopper 3 for flame retardant connected through the right side of the machine body 1, a motor 4 installed at the rear of the machine body 1, a first gear 5 connected to the output end of the motor 4, a second gear 6 meshing with the outer side of the first gear 5, both the first gear 5 and the second gear 6 being rotatably connected to the rear of the machine body 1, a shearing screw 7 connected to the ends of both the first gear 5 and the second gear 6 being rotatably connected to the machine body 1, a discharge port 8 equally spaced on the front of the machine body 1, and a water tank 9 integrally installed on the front of the machine body 1.

[0028] During use, the materials required for glass fiber processing are fed into the feed port 2 at the top of the machine body 1. The flame retardant is placed in the feed hopper 3 on the right side, so that flame retardant components can be added to the glass fiber to improve its performance. The feed hopper 3 is filled to two-thirds of its storage volume. After starting the motor 4, the motor 4 drives the first gear 5 to rotate. The first gear 5 drives the second gear 6 to rotate synchronously, so that the shearing screw 7 inside the machine body 1 runs, thereby shearing and mixing the glass fiber with other materials. Then, the glass fiber is extruded from the discharge port 8 on the front side of the machine body 1. After passing through the water tank 9, the output glass fiber can be cooled and shaped.

[0029] Example 2:

[0030] Based on Embodiment 1, a reinforced shearing mechanism is also disclosed to overlap the shearing of mixed glass fibers and other materials, improving the situation of fiber leakage and sliver breakage at the die opening. Please refer to [link / reference]. Figures 2-4As shown, its specific structure is as follows: A fixing frame 10 is fixed to the rear side of the second gear 6 corresponding to the shearing screw 7. The fixing frame 10 and the contact frame 11 are pressed and abutted. The contact frame 11 is installed on the rear side of the machine body 1. The rear end of the shearing screw 7 corresponding to the second gear 6 and the middle part of the second gear 6 are set as a rectangular structure. A spring is installed between the shearing screw 7 and the rear side of the machine body 1. The fixing frame 10 on the rear side of the shearing screw 7 is set as radial, and a hemisphere is installed at each end of the fixing frame 10. After the fixing frame 10 rotates, the end is pressed and abutted against the contact frame 11. The contact frame 11 is set as an "L" shaped structure. A protrusion is fixed on the opposite surface of the contact frame 11 and the fixing frame 10. After the protrusion abuts against the hemisphere, it pushes the shearing screw 7 to produce displacement. The two shearing screws 7 will also move erroneously while rotating relative to each other. The output end of the shearing screw 7 is connected to the space where the discharge port 8 is located. The glass fiber soaked in the water tank 9 is cooled and output from the discharge port 8.

[0031] During use, when the first gear 5 and the second gear 6 drive the two shearing screws 7 to rotate, the end of the fixing frame 10 on the rear side of the shearing screw 7 on the first gear 5 will intermittently press and abut against the contact frame 11, thereby pushing the shearing screw 7 to rotate while also moving relative to each other, compressing the spring. When the end of the fixing frame 10 is misaligned with the contact frame 11, the spring will drive the shearing screw 7 to move back to its original position. This process repeats, thereby increasing the shearing and mixing strength of glass fiber and gas materials, making the shearing and mixing more thorough and better integrated, and avoiding fiber overflow and breakage during discharge.

[0032] Example 3:

[0033] Based on Embodiment 2, an auxiliary cooling and shaping mechanism is also disclosed. Please refer to [link / reference]. Figure 1 , Figure 3 and Figures 5-6 As shown, its specific structure is as follows: A jet pipe 18 is rotatably connected to the front side of the body 1 at equal angles. The jet pipe 18 is connected to the air pump 19 through a connecting pipe. The air pump 19 is installed on the top front side of the body 1. The output end of the motor 4 drives the cam 12 to rotate synchronously through the sprocket mechanism. The cam 12 is rotatably connected to the left side of the body 1. The front end of the cam 12 abuts against the rack 13. The rack 13 is symmetrically fixed with a limit block 14 on the rear side. The limit block 14 is slidably connected to the transverse groove 15 through the return spring 16. The transverse groove 15 is correspondingly opened on the front side of the body 1. A toothed ring 17 is meshed and connected to the bottom of the rack 13. The toothed ring 17 is fixed to the outside of the rotating shaft of the jet pipe 18. The jet pipe 18 forms a left and right swing blowing structure through the rack 13 and the toothed ring 17.

[0034] During use, the output of motor 4 will also drive cam 12 to rotate synchronously through sprocket mechanism. After cam 12 rotates, it will push rack 13 to slide horizontally. When rack 13 slides, limit block 14 will move in transverse groove 15, thereby compressing return spring 16. When cam 12 rotates to the shortest position, return spring 16 will push limit block 14 to reset, thereby driving rack 13 to move back, so that rack 13 moves horizontally back and forth. After rack 13 moves, it drives jet pipe 18 to swing synchronously through gear ring 17, thereby improving the air cooling effect of glass fiber cooling and molding.
