[0026] To make the technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] This utility model provides a technical solution: (Refer to...) Figure 1 - Figure 5 The present invention discloses an automatic fiberglass drawing machine for cutting yarn, comprising a drawing machine body 1;

[0028] Also includes:

[0029] The drive mechanism 2 is located on the outer wall of the drawing machine body 1 and is used to drive the glass fiber to move.

[0030] The round tube 3 has one end rotatably connected to the outer wall of the wire drawing machine body 1, and several annular grooves 4 are equally spaced on its outer wall;

[0031] Several fixed cutters 5 are fixedly installed in corresponding annular grooves 4. A movable cutter 6 is provided in the annular groove 4, and the movable cutter 6 is offset relative to the corresponding fixed cutter 5. The middle part of the opposite face of the fixed cutter 5 and the corresponding fixed cutter 5 is recessed inward to form a semi-circular groove. An adjustment mechanism 7 is provided in the tube wall of the circular tube 3 to adjust the position of the movable cutter 6.

[0032] In this embodiment, when using the improved glass fiber drawing machine, please refer to... Figure 1 , Figure 2 and Figure 5As shown, the drive mechanism 2 is activated, pushing the glass fiber filament to slide towards the circular tube 3, and causing the end of the glass fiber filament to insert into the annular groove 4, and pass through the circular hole formed by the two semi-circular grooves of the fixed cutter 5 and the moving cutter 6. Then, due to its own gravity, the shorter part of the glass fiber filament end slowly bends and hangs down with the circular tube 3 as the axis, and can fall directly onto the outside of the take-up drum. (The circular tube 3 is located on the top side of the take-up drum of the drawing machine body 1, and the outside of the take-up drum is equipped with an automatic connection mechanism to complete the connection between the end of the glass fiber filament and the take-up drum by bonding or clamping). After the connection between the end of the glass fiber filament and the take-up drum is completed, the drawing machine body 1 is activated, and the take-up drum rotates at a constant speed, gradually winding the glass fiber filament pushed by the drive mechanism 2 to the outer periphery of the take-up drum.

[0033] Please refer to Figure 2 - Figure 5 As shown, after the amount of glass fiber filaments on the take-up drum reaches the threshold, the drive mechanism 2 stops running, the adjustment mechanism 7 starts, and pushes the moving cutter 6 and the fixed cutter 5 to quickly misalign and reposition and reset, thereby cutting the glass fiber filaments. Due to the constraint of the semi-circular groove of the fixed cutter 5 on the end of the glass fiber filament, the position of the end of the glass fiber filament remains unchanged. Then, according to the start of the drive mechanism 2, the glass fiber filament continues to move, and the connection between the end of the glass fiber filament and the take-up drum is re-completed, thereby completing the take-up of the glass fiber filament again. Due to the constraint and limitation of the inner wall of the annular groove 4 on the glass fiber filament, and the natural hanging of the shorter glass fiber filament, the glass fiber filament will hardly scatter and intertwine, thereby avoiding affecting the subsequent take-up of the glass fiber filament by the take-up drum.

[0034] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the other end of the round tube 3 is rotatably fitted with a support plate 8, which is fixedly connected to the outer wall of the wire drawing machine body 1 through a connecting rod;

[0035] In this embodiment, please refer to Figure 1 As shown, (one end of the round tube 3 is rotatably connected to the outer wall of the wire drawing machine body 1 through the base), and with the support plate 8, the round tube 3 can be supported by both ends to prevent the round tube 3 from being fixed on one side due to its own weight affecting the stability of the connection between the base and the round tube 3.

[0036] In a further preferred embodiment of this utility model, such as Figure 5 As shown, the movable cutter 6 is provided with an elastic strip 9 on the side close to the corresponding fixed cutter 5, and both ends of the elastic strip 9 are fixedly connected to the corresponding movable cutter 6.

[0037] In this embodiment, please refer to Figure 5As shown, when the fixed cutter 5 and the moving cutter 6 complete the cutting of the glass fiber filament, the elastic strip 9 is simultaneously driven to come into contact with the glass fiber filament. As the middle part of the elastic strip 9 is stretched and deformed, a pushing force can be applied to the end of the glass fiber filament. Combined with the contact between the inner wall of the semi-circular groove of the fixed cutter 5 and the end of the fiber filament, the end of the drawing machine body 1 is clamped and fixed to prevent the glass fiber filament from slipping out of the semi-circular groove of the fixed cutter 5.

[0038] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a driver 10 is fixedly mounted on the support plate 8, and the driving end of the driver 10 is fixedly sleeved on the other end of the round tube 3.

[0039] In this embodiment, please refer to Figure 1 As shown, when there is a moving gap between the end of the glass fiber filament and the take-up drum, the drive mechanism 2 stops running and the driver 10 is started (the driver 10 is mainly composed of a housing, a gear ring, a transmission gear and a motor 22). The started driver 10 drives the cylinder to rotate. As the glass fiber filament comes into contact with the inner wall of the semi-circular groove, the glass fiber filament located in the annular groove 4 undergoes a corresponding deformation, thereby further adjusting the position of the end of the glass fiber filament so that the glass fiber filament is in complete contact with the take-up drum.

[0040] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the drive mechanism 2 includes two drive rollers 21, one end of which is rotatably connected to the outer wall of the wire drawing machine body 1, and the other end of the drive roller 21 is rotatably connected to the support plate 8. A motor 22 is fixedly mounted on the support plate 8, and the drive end of the motor 22 is fixedly connected to the other end of the corresponding drive roller 21.

[0041] In this embodiment, please refer to Figure 2 As shown, when using the device, the end of the glass fiber filament is first inserted between the two drive rollers 21. At the same time, the motor 22 starts to drive the drive roller 21 at the bottom to rotate. Thus, the glass fiber filament is gradually passed between the two drive rollers 21 by the clamping of the two drive rollers 21, and the end of the glass fiber filament is pushed towards the round tube 3. The device has a high degree of automation.

[0042] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a guide plate 23 is provided between the circular tube 3 and the corresponding drive roller 21, and the two ends of the guide plate 23 are fixedly connected to the outer wall of the wire drawing machine body 1 and the support plate 8 respectively. The two sides of the guide plate 23 are in contact with the outer peripheral wall of the circular tube 3 and the outer peripheral wall of the corresponding drive roller 21 respectively.

[0043] In this embodiment, please refer to Figure 2 As shown, the glass fiber filaments that move out between the two drive rollers 21 slide to the top side of the guide plate 23. As the guide plate 23 supports the glass fiber filaments, the glass fiber filaments between the circular tube 3 and the drive rollers 21 bend and deform, and fall downwards, affecting the use of the device. (The bottom end of the semi-circular groove is coplanar with the top end of the inner arc wall of the annular groove 4, so that the glass fiber filaments that slide out from the guide plate 23 can slide directly into the annular groove 4 and pass through the corresponding semi-circular groove).

[0044] In a further preferred embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the adjustment mechanism 7 includes an interface 71, which is rotatably installed in the opening of the round tube 3. An air storage groove 72 is provided in the wall of the round tube 3, and the interior of the air storage groove 72 is connected to the interior of the round tube 3 through a connecting hole 73. A piston rod 74 is slidably installed in the air storage groove 72, and the driving end of the piston rod 74 is fixedly connected to the corresponding moving cutter 6.

[0045] In this embodiment, please refer to Figure 3 and Figure 4 As shown, (the connection end of interface 71 is connected to an external injection and extraction device via a gas supply pipe). When it is necessary to cut the glass fiber filaments, the injection and extraction device is activated, and the corresponding amount of gas is quickly injected into the circular tube 3 through interface 71, so that a high-pressure chamber of corresponding strength is formed in the circular tube 3 and the gas storage tank 72. The gas pushes the piston rod 74 of corresponding length out of the gas storage tank 72, so that the fixed cutter 5 and the moving cutter 6 are misaligned and attached, completing the glass fiber filament cutting operation. After the glass fiber filaments are cut, the main extraction device extracts the gas injected into the circular tube 3 through interface 71, so that a negative pressure chamber of corresponding strength is formed in the circular tube 3 and the gas storage tank 72, so that the piston rod 74 is re-inhaled into the gas storage tank 72, so that the moving cutter 6 slides back to reset. The device has a high degree of automation.

[0046] In a further preferred embodiment of this utility model, such as Figure 4 and Figure 5 As shown, a rectangular groove 11 is provided on the inner ring wall of the annular groove 4, and the bottom of the moving cutter 6 is inserted into the rectangular groove 11 and contacts the inner wall of the rectangular groove 11.

[0047] In this embodiment, please refer to Figure 5 As shown, during the sliding process, the moving cutter 6 slides along a linear trajectory due to the mutual contact between the moving cutter 6 and the inner wall of the rectangular groove 11, so as to avoid the moving cutter 6 and the fixed cutter 5 from contacting each other and affecting the use of the device.

[0048] Working principle: When this improved glass fiber drawing machine is in use, the motor 22 starts and drives the drive roller 21 at the bottom to rotate at a constant speed. Then, the end of the glass fiber filament is inserted between the two drive rollers 21. The glass fiber filament is gradually pulled between the two drive rollers 21 by the clamping of the two drive rollers 21. Then, the end of the glass fiber filament moves out from between the two drive rollers 21 and moves to the support plate 8. Due to the support of the support plate 8, the glass fiber filament slides in a straight state. After the glass fiber filament slides out from the support plate 8, it is directly inserted into the annular groove 4 and passes through the two semi-circular grooves.

[0049] It should be noted that when the end of the glass fiber filament slides out from the support plate 8, the position of the end of the glass fiber filament can also be manually adjusted to avoid bending and deformation of the end of the glass fiber filament, which would prevent it from passing through the two semi-circular grooves.

[0050] After the glass fiber filament slides out of the annular groove 4, due to its own gravity, the glass fiber filament end slowly bends and hangs down around the circular tube 3 as the axis, and then falls directly onto the outside of the take-up drum. At this time, the drawing machine body 1 starts and completes the connection between the glass fiber filament end and the outer wall of the take-up drum through the automatic connection mechanism. After the glass fiber filament end and the take-up drum are connected, the take-up drum rotates at a constant speed and gradually winds the glass fiber filament pushed by the drive mechanism 2 to the outer periphery of the take-up drum.

[0051] It should be noted that during the process of the glass fiber filament sliding in the semi-circular groove, the movable cutter 6 and the fixed cutter 5 cooperate with each other to scrape off the broken glass fiber filaments attached to the glass fiber filament.

[0052] Once the amount of glass fiber filaments on the winding drum reaches the threshold, the motor 22 stops running, and the air injection and extraction device starts. The corresponding amount of gas is quickly injected into the circular tube 3 through the interface 71. At the same time, some gas flows into the gas storage tank 72 through the connection hole 73. The gas pushes the piston rod 74 of the corresponding length out of the gas storage tank 72, thereby causing the moving cutter 6 to slide in the rectangular groove 11 and quickly misalign and fit with the fixed cutter 5 to cut the glass fiber filaments. After the glass fiber filaments are cut, the main air extraction device extracts the gas injected into the circular tube 3 through the interface 71, so that a negative pressure chamber of corresponding strength is formed in the circular tube 3 and the gas storage tank 72. This causes the piston rod 74 to be sucked back into the gas storage tank 72, so that the moving cutter 6 can quickly slide back and reset.

[0053] Subsequently, the motor 22 restarts, and the drive roller 21 continues to push the glass fiber filament. Due to the mutual contact between the glass fiber filament and the inner wall of the tobacco and the elastic strip 9, the end of the glass fiber filament continues to pass through the two semi-circular grooves and falls back to the outer periphery of the take-up drum as described above.

[0054] When the flow of external gas causes the end of the glass fiber filament to be unable to adhere to the outer wall of the take-up drum, the motor 22 stops running, the driver 10 starts to drive the circular tube 3 to rotate, and drives the fixed cutter 5 and the moving cutter 6 to rotate synchronously. Thus, through the mutual contact between the inner wall of the semi-circular groove and the glass fiber filament, the glass fiber filament located in the annular groove 4 undergoes a corresponding deformation, so that the end of the glass fiber filament swings towards the outer wall of the take-up drum, and finally makes the end of the glass fiber filament adhere tightly to the take-up drum. After the end of the glass fiber filament is fixed to the outer wall of the take-up drum, the driver 10 drives the circular tube 3 to rotate in the opposite direction to reset, and the glass fiber filament can be re-wound according to the above.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
