Description

Technical Field

[0001] This invention relates to the field of yarn-blocking devices, specifically to a yarn-blocking device for direct yarn from non-metallic mineral products. Background Technology

[0002] Non-metallic mineral direct yarn, often referring to alkali-free glass fiber direct untwisted roving, is a continuous inorganic fiber bundle made directly from mineral raw materials such as pyrophyllite and quartz sand through high-temperature melting and drawing from a stencil. Each filament is only a few micrometers in size and possesses high strength, corrosion resistance, and insulation properties. During high-speed drawing and shearing with different bobbins, broken filaments are prone to scattering and drifting, causing tangled, entangled, and drifting filaments, affecting adjacent yarn bundles and product quality. Traditional methods struggle to intercept these filaments in time, requiring manual cleaning, resulting in low efficiency and high losses. A filament-blocking device can precisely intercept broken filaments at the moment of shearing, preventing scattering and entanglement, ensuring continuous and stable production, and improving product cleanliness and yield.

[0003] However, existing yarn-blocking devices are difficult to stop and limit in time after the yarn is cut during use, which can easily lead to yarn scattering, disordered entanglement, and pile-up of messy yarn, resulting in insufficient operational stability and easy to cause equipment jamming and increased yarn loss. Summary of the Invention

[0004] The purpose of this invention is to provide a direct yarn blocking device for non-metallic mineral products. By setting up a yarn blocking part, it solves the problem that existing yarn blocking devices are difficult to complete the blocking and limiting in time after the yarn is cut, which easily leads to yarn scattering, disordered entanglement, and pile-up of messy yarn, resulting in insufficient operational stability and easy to cause equipment jamming and increased yarn loss.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a direct yarn blocking device for non-metallic mineral products, comprising a fixed plate, and further comprising: a yarn blocking part mounted on the fixed plate; an angle adjusting part disposed on the fixed plate; a height adjusting part mounted on the angle adjusting part; the yarn blocking part including a shearing assembly disposed on the fixed plate; and a driving assembly mounted on the fixed plate; the shearing assembly including a multi-stage electric telescopic rod disposed above the fixed plate, the outer wall of which is fixedly connected to a connecting plate, and a yarn blocking rod disposed on the right side of the connecting plate. The output end of the telescopic rod is provided with a second connecting plate, and the threaded rod is fixedly connected to the second connecting plate. The right side of the second connecting plate is fixedly connected to a third connecting plate. The third connecting plate has a slot, and two shearing rods are hingedly mounted on the third connecting plate. The two shearing rods are provided with hinges. The output end of the multi-stage electric telescopic rod passes through the second connecting plate. The two shearing rods are arranged in a mirror image. The hinges include two hinge rods hinged to the two shearing rods. The left side of the two hinge rods is hinged to a hinge block. The left side of the hinge block is fixedly connected to the output end of the multi-stage electric telescopic rod. The two hinge rods are arranged in a mirror image.

[0006] Furthermore, the angle adjustment unit includes a connecting component disposed on a fixed plate; and a pressing component mounted on the fixed plate.

[0007] Furthermore, the height adjustment part includes a limiting component disposed on the angle adjustment part; and a pushing component disposed on the angle adjustment part.

[0008] Furthermore, the driving assembly includes a plurality of sliding rods fixedly connected to the right side of the connecting plate one, a limiting plate fixedly connected to the right side of each of the sliding rods, and the sliding rods all pass through the connecting plate two, with the connecting plate two slidably connected to the sliding rods.

[0009] Furthermore, the connecting assembly includes a connecting rod fixedly connected to the top of the fixed plate, and a fixing ring is fixedly connected to the outer wall of the connecting rod. The fixing ring has a plurality of limiting grooves, which are distributed in a circular array.

[0010] Furthermore, the pressing assembly includes a fixed rod disposed on the outer wall of the connecting rod, a plurality of limiting blocks being provided on the inner wall of the fixed rod, a spring being disposed inside the fixed rod, the top of the spring being fixedly connected to the fixed rod, the bottom of the spring being fixedly connected to the connecting rod, a handle being fixedly connected to the top of the fixed rod, the limiting blocks being adapted to the limiting groove, and a friction pad being provided on the outer wall of the handle.

[0011] Furthermore, the limiting component includes two protruding plates fixedly connected to the outer wall of the fixing rod, an adapter ring slidably connected to the outer wall of the fixing rod, and two protrusions fixedly connected to the inner wall of the adapter ring, the two protrusions being mirror-shaped.

[0012] Furthermore, the pushing assembly includes a second fixed ring slidably connected to the outer wall of the fixed rod. The bottom of the second fixed ring is fixedly connected to two conical plates, the bottoms of the two conical plates extending into the adapter ring. The conical plates are adapted to the protrusions. The outer wall of the fixed rod is fitted with a second spring. The top of the second spring is fixedly connected to the second fixed ring, and the bottom of the second spring is fixedly connected to the adapter ring. The initial state of the second spring is a stretched state.

[0013] The present invention has the following beneficial effects: 1. This invention, by setting up a yarn-blocking part, relies on a multi-stage electric telescopic rod as a single power source to complete step-by-step linkage actions: the telescopic rod extends first, pushing the two connecting plates to move laterally, causing the direct yarn to be inserted into the slot, while simultaneously driving the yarn-blocking rod forward to block the direct yarn's path; after the two connecting plates reach the limiting plate and stop, the telescopic rod continues to extend, using the angle transmission structure of the hinge block and hinge rod to drive the two sets of shearing rods to swing relative to each other in a lever-like manner, and using the biting of the shearing rod ends to complete the yarn cutting. The entire process is achieved through mechanical linkage and timing coordination, synchronously realizing the orderly action of first blocking the yarn and then cutting. The cutting and yarn-blocking operations are connected and smooth, and while cutting the yarn, the scattered yarn bundles are intercepted in time, effectively avoiding the phenomenon of messy and floating yarn, improving the stability and cleanliness of the direct yarn cutting operation, and reducing the probability of production failure.

[0014] 2. This invention features an angle adjustment unit. By manually pulling the handle, the fixed rod moves upward and stretches the spring, separating the limiting block from the limiting groove and releasing the angle lock. Then, rotating the fixed rod simultaneously rotates the height adjustment unit and the wire-blocking unit, allowing for flexible angle adjustment of the wire-blocking rod. After adjustment, releasing the handle allows the spring's rebound force to reset the fixed rod, re-engaging the limiting block into the limiting groove, achieving automatic locking of the structure and rapid positioning and fixing of the wire-blocking rod angle. This allows for flexible adaptation to various wire bundle specifications and routing angles according to production conditions, improving the device's adaptability and operational stability, and ensuring long-term reliable wire-blocking operations.

[0015] 3. This invention, by setting a height adjustment unit, first achieves overall stable installation through a fixing plate. During height adjustment, the second fixing ring is pulled upward, driving the conical plate upward and stretching the second spring, releasing the pressing fit between the conical plate and the protrusion, reducing the friction limit between the conical plate and the protrusion. Then, the adapter ring is pulled up and down, synchronously driving the thread-stopping rod and the linkage assembly to rise and fall as a whole, completing the height adjustment. After adjustment, the second fixing ring is released, and the second spring rebounds, pulling the conical plate downward. The lateral pushing force is generated by the inclined surface of the protrusion and the conical plate, increasing the friction of the contact surface. The position is locked by the friction self-locking structure, realizing the rapid adjustment and fixation of the thread-stopping rod height. The working height can be adjusted according to the actual wire bundle routing requirements, adapting to various production conditions, improving the versatility and installation adaptability of the device, and ensuring the stability of the thread-stopping and shearing operations.

[0023] The height adjustment unit 4 includes a limiting component 41, which is disposed on the angle adjustment unit 3; and a pushing component 42, which is disposed on the angle adjustment unit 3. The limiting component 41 includes two protruding plates 411 fixedly connected to the outer wall of the fixing rod 321. An adapter ring 412 is slidably connected to the outer wall of the fixing rod 321. Two protrusions 413 are fixedly connected to the inner wall of the adapter ring 412. The two protrusions 413 are arranged in a mirror image. The pushing component 42 includes a second fixing ring 421 slidably connected to the outer wall of the fixing rod 321. Two conical plates 422 are fixedly connected to the bottom of the second fixing ring 421. The bottom of the conical plate 422 extends into the adapter ring 412. The conical plate 422 is adapted to the protrusion 413. The outer wall of the fixing rod 321 is fitted with a second spring 423. The top of the second spring 423 is fixedly connected to the second fixing ring 421, and the bottom of the second spring 423 is fixedly connected to the adapter ring 412. The initial state of the second spring 423 is a stretched state. By setting the height adjustment part 4, the height of the wire-blocking rod can be quickly adjusted and fixed. The working height can be adjusted according to the actual wire bundle routing requirements, adapting to various production conditions, improving the versatility and installation adaptability of the device, and ensuring the stability of wire blocking and shearing operations.

[0024] It should be noted that the control of the multi-stage electric telescopic pole 211 in this application can be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.

[0025] In use, first fix the fixing plate 111 to the direct yarn production device. Then, adjust the height and angle of the thread-stopping rod 213 according to the model and installation position of different devices. When adjusting the height, first pull the fixing ring 421 upward. At this time, the fixing ring 421 will move the tapered plate 422 upward. When the fixing ring 421 moves upward, it will stretch the spring 423. As it moves, the tapered plate 422 will stop contacting the protrusion 413. At this time, the protrusion 413 will no longer push the tapered plate 422 closer to the protrusion plate 411. Therefore, the friction between the tapered plate 422 and the protrusion plate 411 will also decrease. At this time, pull the adapter ring 412 downward or upward. When the adapter ring 412 moves, the multi-stage electric telescopic rod 211, the connecting plate 1 212, and the stop rod 213 will also move accordingly. After the adjustment is completed, stop pulling the fixed ring 2 421. At this time, the spring 2 423 will pull the fixed ring 2 421 and the conical plate 422 downward. When the conical plate 422 moves downward, it will contact the protrusion 413. Because the protrusion 413 and the conical plate 422 are in inclined contact, during the continuous downward movement, the protrusion 413 will push the pushing component 42 inward. The friction between the conical plate 422 and the protrusion 411 will increase as the contrusion continues to push inward, thereby achieving the effect of adjusting the height of the stop rod 213. When adjusting the angle, pull the handle 324 upward. The handle 324 will move the fixed rod 321 upward. During the movement, the fixed rod 321 will stretch the spring 323. As the movement progresses, the limiting block 322 inside the fixed rod 321 will disengage from the limiting groove 313 on the fixed ring 312. After disengagement, the fixed rod 321 can be rotated. The fixed rod 321 will then rotate the height adjustment part 4 and the stop screw part 2. During the rotation, the angle of the stop screw rod 213 can be adjusted. After the adjustment is completed, release the handle 324. The spring 323 will pull the fixed rod 321 downward. When the fixed rod 321 moves, the limiting block 322 on its inner wall will lock onto the limiting groove 313 again, thereby locking the angle after adjustment and achieving the effect of adjusting the angle of the stop screw rod 213. After adjustment, it can be put into use. During use, when it is necessary to cut the direct yarn and stop the yarn, the multi-stage electric telescopic rod 211 is activated. The multi-stage electric telescopic rod 211 will push the connecting plate 214 to the right. As it moves, the direct yarn will be stuck in the slot 216. At this time, the continuously moving connecting plate 214 will reach the end of the slide rod 221. At this time, the continuously moving connecting plate 214 will contact the limiting plate 222. After contact, the connecting plate 214 will stop moving. The yarn-stopping rod 213 will then block in front of the direct yarn, while the multi-stage electric telescopic rod 211 will continue to extend. At this time, the extended multi-stage electric telescopic rod 211 will push the hinge block 219, and through the hinge block 219, push the hinge rod 218 and the shearing rod 217. Because the hinge rod 218 has an initial angle, the hinge rod 218 will push the left side of the two shearing rods 217 outward. When the left side of the shearing rod 217 is pushed, the right side will move closer to each other. As they move closer, they will come into contact with the direct yarn. As the shearing rods 217 move closer, a shearing action will be formed, cutting the direct yarn. At this time, the ejected direct yarn will be intercepted by the yarn-blocking rod 213, thereby achieving the yarn-blocking effect.
