Description

Technical Field

[0001] This invention belongs to the field of glass fiber yarn processing technology, and specifically relates to a glass fiber yarn drying and weft insertion device. Background Technology

[0002] Glass fiber is a high-performance inorganic non-metallic material with many varieties. Its advantages include good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. However, its disadvantages include brittleness and poor wear resistance. It is made from six minerals—pyrophyllite, quartz sand, limestone, dolomite, borocalcite, and boromagnesia—through high-temperature melting, drawing, winding, and weaving processes. The diameter of its single filaments ranges from a few micrometers to over twenty micrometers, equivalent to 1 / 20 to 1 / 5 the diameter of a human hair. Each bundle of fiber consists of hundreds or even thousands of single filaments. Glass fiber is commonly used as a reinforcing material in composite materials, an electrical insulation material, a thermal insulation material, and in circuit boards, among other applications across various sectors of the national economy.

[0003] When fiberglass yarn is used for weaving, it needs to be twisted to remove the raw yarn from the yarn cake and complete the twisting and winding to make a yarn tube that meets the requirements. The raw yarn containing moisture has an adverse effect on the subsequent processing steps, so it is necessary to dry the raw yarn.

[0004] In existing technologies, most methods involve placing the yarn cake in a sealed drying chamber for heating and drying, and then performing the twisting operation after a period of drying. However, since the yarn cake is rolled up, the above drying method can lead to inconsistent drying effects inside and outside the yarn cake, which can easily affect the quality of the glass fiber yarn. Furthermore, the step-by-step operation of drying before twisting results in low work efficiency. Summary of the Invention

[0005] In view of the above-mentioned problems in the prior art, the purpose of this invention is to provide a glass fiber yarn drying and weft insertion device that can produce continuously and efficiently, effectively improving fabric quality and production efficiency.

[0006] A glass fiber yarn drying and weft insertion device includes a movable heating component and a rotating component for driving the workpiece to be dried to rotate. When the workpiece to be dried rotates with the rotating component, the heating component sprays hot air onto the workpiece to be dried for drying. The rotating component includes an upper clamping plate and a lower clamping plate. The lower clamping plate is provided with a hollow intermediate column for receiving the workpiece to be dried. The intermediate column is provided with a flip-up rotating block. The upper clamping plate is provided with a protrusion adapted to the intermediate column. The upper clamping plate moves downward to insert the protrusion into the interior of the intermediate column to drive the rotating block to flip, so that one end of the flipped rotating block abuts against the inner wall of the workpiece to be dried.

[0007] Preferably, the intermediate column has an installation groove adapted to the rotating block, the rotating block is installed in the installation groove, one end of the rotating block is located inside the intermediate column and is connected to the abutment block through a guide block, the abutment block also has a guide groove, the guide block slides along the guide groove, and the abutment block is set inside the intermediate column by the elastic action of a spring.

[0008] Preferably, the abutment block is connected to the spring via a connecting block, one end of the spring abuts against the inner wall of the intermediate column, and a slider is provided between the other end of the spring and the connecting block, the slider contacting the interior of the intermediate column.

[0009] Preferably, the lower clamping plate is rotated by a motor via a rotating rod, and the upper clamping plate is moved up and down by an electric telescopic rod via a lifting rod, wherein the electric telescopic rod is installed inside the fixed column.

[0010] Preferably, the bottom of the protrusion is provided with a movable rotating bead embedded in the middle body, and the movable rotating bead is adapted to the inner diameter of the middle post.

[0011] Preferably, two sets of heating components are symmetrically installed on the processing table, and the relative distance between the two sets of heating components is adjustable. The rotating component is located between the two sets of heating components. The heating component includes two sliding air outlet plates distributed vertically. The two sliding air outlet plates are driven by a driving mechanism to move closer or further apart from each other along a fixed rod. The sliding air outlet plates are provided with an array of nozzles, and the nozzles are connected to the air inlet pipes installed on the sliding air outlet plates.

[0012] Preferably, the driving mechanism includes a driving rod that is driven to swing by a telescopic cylinder. The driving rod is located between two sliding air outlet plates and is connected to the two sliding air outlet plates respectively through a connector.

[0013] Preferably, the telescopic end of the telescopic cylinder is connected to one end of the drive rod via a moving block. When the drive rod is driven by the telescopic cylinder to swing, it drives the sliding air outlet plate to move along the fixed rod via the connecting piece.

[0014] Preferably, the connector includes a first fixed tube, a connecting rod, and a second fixed tube. The first fixed tube and the second fixed tube are connected by the connecting rod. The second fixed tube is sleeved on the drive rod, and the first fixed tube is sleeved on the force-bearing rod. The force-bearing rod is mounted on the sliding air outlet plate by a mounting block.

[0015] Preferably, the heating assembly further includes a movable base rod, which has an inverted U-shaped structure. The processing table has a movable groove for sliding installation of the movable base rod. The fixed rod is connected to the movable base rod. The movable groove has a screw rod connected to the movable base rod inside. The screw rod is driven by a drive motor to rotate, thereby driving the movable base rod to move along the movable groove.

[0016] The beneficial effects of this invention are: the glass fiber yarn drying and weft feeding device, through the structural design of the rotating component and the heating component, allows the yarn cake to be sleeved on the rotating component and rotate with the rotation of the rotating component, which can realize the drying of the yarn cake during the twisting operation. As the twisting operation proceeds, the raw yarn is continuously peeled off the yarn cake, which can ensure the drying effect of the raw yarn.

[0017] By setting up upper and lower clamping plates, the installation efficiency of the wire cake is increased. The upper clamping plate can move closer to the lower clamping plate to clamp the wire cake. The protrusion slides into the interior of the middle column, and the movable ball at the bottom of the protrusion contacts the abutment. After the abutment is subjected to force, it moves downward. At this time, the spring is compressed, and the slider also slides down along the middle column. During the descent, the abutment will apply pressure to the rotating block. The rotating block rotates with the rotating connection with the mounting groove as the support point. One end of the rotating block slides below the abutment as it descends. At this time, the inner wall of the wire cake sleeved on the middle column contacts the other end of the rotating block, which has a good fixing effect on the wire cake and is easy to operate.

[0018] Thanks to the opposing heating components, the rotating silk cake can be dried and heated in both directions. The stepped nozzles can effectively increase the air drying range. The nozzles are mounted on the sliding air outlet plate, which is symmetrically arranged on one side of the silk cake. Through its flexibility, the air outlet position can be continuously adjusted during the drying process. The air outlet position is not limited to one place, which can effectively improve the drying quality of the silk cake.

[0019] As the telescopic cylinder extends and retracts, the drive rod moves back and forth. When moving backward, the two connecting rods form a V-shape, which pulls the force rod and causes the sliding air outlet plate to move closer to the fixed rod. When the drive rod moves forward, the two connecting rods are in a vertical position, pushing the force rod in opposite directions, which causes the sliding air outlet plate to move further away from the fixed rod. The position of the nozzle air outlet is adjusted by adjusting the position of the sliding air outlet plate. Attached Figure Description

[0029] Example 1

[0030] like Figure 1 As shown, a glass fiber yarn drying and weft feeding device includes a movable heating component 6 and a rotating component for driving the workpiece to be dried to rotate. When the workpiece to be dried rotates with the rotating component, the heating component 6 sprays hot air onto the workpiece to be dried for drying. Through the structural design of the rotating component and the heating component 6, the yarn cake is sleeved on the rotating component and rotates with the rotating component, which can realize the drying of the yarn cake during the twisting operation. As the twisting operation proceeds, the raw yarn is continuously peeled off the yarn cake, which can ensure the drying effect of the raw yarn.

[0031] like Figure 1 , Figure 2As shown, two sets of heating components 6 are symmetrically installed on the upper surface of the processing table 1. A rotating rod 14 is rotatably installed between the two sets of heating components 6 on the upper surface of the processing table 1. A lower clamping plate 13 is fixedly installed on the upper surface of the rotating rod 14. An upper clamping plate 9, which does not contact the lower clamping plate 13, is provided above the lower clamping plate 13. A lifting rod 5 is rotatably connected to the upper surface of the upper clamping plate 9. The lifting rod 5 has an L-shaped structure, and a fixed column 4 is movably connected to the end away from the upper clamping plate 9. The silk cake is placed between the upper clamping plate 9 and the lower clamping plate 13, and the center of the silk cake is fitted with... On the intermediate column 11, the lifting rod 5 then descends along the fixed column 4. An electric telescopic rod (not shown in the figure) connecting the lifting rod 5 is installed inside the fixed column 4. When the lifting rod 5 descends, the upper clamping plate 9 can move closer to the lower clamping plate 13. A rotating rod 14 is fixedly connected to the bottom of the lower clamping plate 13. The rotating rod 14 is set vertically, and a motor that drives the rotating rod 14 is installed at the bottom of the processing table 1. The motor drives the rotating rod 14 and the lower clamping plate 13 to rotate, thereby driving the wire cake sleeved on the lower clamping plate 13 to rotate.

[0032] like Figure 2 , Figure 3 As shown, a protrusion 10 is installed on the surface of the upper clamping plate 9 facing the lower clamping plate 13. The bottom of the protrusion 10 is provided with a movable rotating ball 18 embedded in the body. A middle column 11 is fixedly installed on the upper surface of the lower clamping plate 13. The middle column 11 has a hollow structure with an open upper surface and a stop block 17 is elastically installed inside. The protrusion 10 slides in along the top of the middle column 11, and the stop block 17 fits against the movable rotating ball 18. The setting of the movable rotating ball 18 is conducive to the smooth rotation of the lower clamping plate 13.

[0033] Please refer to the following carefully. Figure 4 A connecting block 20 is fixedly connected to the bottom of the abutment block 17. A slider 19 is installed below the connecting block 20. A vertically arranged spring 21 is fixed to the bottom of the slider 19. The bottom end is fixedly connected to the bottom end face of the intermediate column 11. An installation groove 12 is distributed around the outer circular surface of the intermediate column 11. A rotatable rotating block 16 is rotatably installed inside the installation groove 12. One end of the rotating block 16 extends out of the interior of the intermediate column 11 and is movably connected to a guide block 22. A guide groove is horizontally opened on the bottom end face of the abutment block 17. The guide block 22 slides horizontally along the guide groove.

[0034] In addition, such as Figure 1 , Figure 5As shown, the heating assembly 6 includes a fixed rod 23, a movable base rod 26, and a sliding air outlet plate 24. The movable base rod 26 has an inverted U-shaped structure. A movable groove 2 is horizontally provided on the upper surface of the processing table 1 for the movable base rod 26 to be slidably installed. The fixed rod 23 is vertically arranged on the upper surface of the movable base rod 26. Two sets of fixed rods 23 are distributed at intervals. The movable groove 2 is provided with a screw connecting the movable base rod 26. A drive motor 3 connecting the screw is installed on the outer wall of the processing table 1. The drive motor 3 drives the screw to rotate, thereby causing the movable base rod 26 to move along the movable groove 2 on the screw.

[0035] Specifically, multiple nozzles 35 are mounted on the front of the sliding air outlet plate 24, arranged in an array and connected to the sliding air outlet plate 24. The interior of the sliding air outlet plate 24 is hollow, and an inflation pipe 8 is also provided inside the sliding air outlet plate 24. The inflation pipe 8 is horizontally arranged and its end is connected to an input pipe 7.

[0036] Working principle: In use, the fiberglass yarn drying and weft feeding device places the yarn cake between the upper clamping plate 9 and the lower clamping plate 13, with the center of the yarn cake fitted onto the intermediate column 11. Then, the lifting rod 5 descends along the fixed column 4. An electric telescopic rod (not shown in the figure) connecting the lifting rod 5 is installed inside the fixed column 4. When the lifting rod 5 descends, the upper clamping plate 9 can move closer to the lower clamping plate 13. At this time, the protrusion 10 slides into the interior of the intermediate column 11, and the movable ball 18 at the bottom of the protrusion 10 contacts the abutment 17.

[0037] After the abutment block 17 is subjected to force, it moves downward. At this time, the spring 21 is compressed, and the slider 19 also slides down along the middle column 11. During the descent, the abutment block 17 will apply pressure to the rotating block 16. The rotating block 16 rotates with the rotating connection point with the mounting groove 12 as the support point. One end of the rotating block 16 slides below the abutment block 17 as the abutment block 17 descends. At this time, the inner wall of the silk cake sleeved on the middle column 11 contacts the other end of the rotating block 16. When the rotating block 16 rotates to press against the inner wall of the silk cake, the lifting rod 5 can stop descending. At this time, the motor located below the processing table 1 is started, so that the rotating rod 14 is subjected to force and rotates, and the silk cake can rotate, and the raw silk is drawn out from the silk cake.

[0038] It should be noted that when not in use, the heating component 6 is moved to the side of the processing table 1 for easy loading and unloading of the silk cake. The movement of the heating component 6 relies on the cooperation of the screw and the moving base rod 26. The screw inside the moving groove 2 is driven by the drive motor 3 to rotate, causing the moving base rod 26 to move along the upper surface of the processing table 1, moving closer to or away from the silk cake.

[0039] The input pipe 7 is connected to the heated compressed air. The hot air enters the inflation pipe 8 and is then sprayed out by multiple nozzles 35. The nozzles 35 are directed towards the yarn cake to provide temperature to the yarn cake. In practice, the compressed air heating equipment is equipped with a controller that can adjust the temperature accordingly. It is also equipped with a temperature detector that monitors the temperature in real time. The temperature is detected by thermal sensing. If the temperature exceeds the set range, an alarm will be triggered to remind the weaving workers.

[0040] Example 2

[0041] like Figures 5 to 7 As shown, the structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the sliding air outlet plate 24 of this embodiment is slidably installed between two sets of fixed rods 23, and a drive mechanism 25 connecting the two sets of sliding air outlet plates 24 is installed on the fixed rods 23.

[0042] Specifically, the drive mechanism 25 includes a first fixed tube 27, a second fixed tube 31, a force-bearing rod 28, and a telescopic cylinder 34. Two force-bearing rods 28 are horizontally spaced and correspond to two sets of sliding air outlet plates 24 respectively. Mounting blocks 15 protrude from the sliding air outlet plates 24. Two sets of mounting blocks 15 are symmetrically spaced and fixed between them with horizontal force-bearing rods 28. The first fixed tube 27 is sleeved on the outside of the force-bearing rods 28. A connecting rod 29 is fixedly connected to the outer wall of the first fixed tube 27. The end of the connecting rod 29 away from the first fixed tube 27 is connected to the second fixed tube 31. A drive rod 30 passes horizontally through the inside of the second fixed tube 31. Two sets of the second fixed tube 31 are spaced apart from the outside of the drive rod 30. A moving block 33 is fixedly connected to the end of the drive rod 30. The moving block 33 is fixedly installed at the telescopic end of the telescopic cylinder 34. The other end of the telescopic cylinder 34 is fixedly installed on a fixed frame 32. The fixed frame 32 is fixedly installed on a fixed rod 23.

[0043] During the process of hot air being ejected from nozzle 35, the position of nozzle 35 can be adjusted by drive mechanism 25, allowing nozzle 35 to emit air in a movable manner. The specific process is as follows: telescopic cylinder 34 is activated to extend and retract, driving drive rod 30 to move via moving block 33. After drive rod 30 moves, second fixed pipe 31 on the outer wall pulls first fixed pipe 27 via connecting rod 29, thereby causing force rod 28 to be forcefully moved, causing mounting block 15 to shift. Sliding air outlet plate 24 is then forcefully moved along fixed rod 23, thereby causing nozzle 35 to... The air outlet of the 5 is not limited to one place, which can effectively improve the drying range of the silk cake. As the telescopic cylinder 34 extends and retracts, the drive rod 30 moves back and forth. When it moves backward, the two connecting rods 29 are in a V-shape, and the force rod 28 is pulled to drive the sliding air outlet plate 24 to move closer to each other along the fixed rod 23. When the drive rod 30 moves forward, the two connecting rods 29 are in a vertical state, pushing the force rod 28 in the opposite direction, and the sliding air outlet plate 24 moves away from each other along the fixed rod 23, thus improving the drying range.
