Description

Technical Field

[0001] This utility model belongs to the technical field of glass fiber stub cutting equipment, specifically relating to a glass fiber online stub cutting continuous filament feeding device. Background Technology

[0002] Minimal staple fiber possesses high breaking strength and low breaking elongation, low shrinkage in boiling water or hot air, high dispersibility in media, antistatic properties, low melting point, and antibacterial properties, making it widely applicable in aerospace, transportation, machinery, electronics, medical, automotive, chemical, wind power, and construction industries. The most crucial quality indicator for mini staple fiber products is the uniformity of fiber cut length. Therefore, the most critical aspect of equipment for producing mini staple fibers is the ability to continuously and accurately cut the fibers to the required length.

[0003] Since the distance between two adjacent blades on the cutter roller is the length of the chopped fiber obtained, if longer glass fibers are to be cut, the distance between the two adjacent blades needs to be increased. Existing technology includes a high-speed glass fiber chopping machine, comprising a swaying mechanism. This mechanism includes a swaying cylinder, a swaying rod, a swaying shaft, a bearing seat, and a swaying arm. The swaying rod is inclined upwards, and the swaying cylinder drives the swaying arm to swing the swaying rod downwards, pressing down the fiber filaments located above the rubber roller. This causes the fiber filaments to move towards the meshing area between the cutter roller and the rubber roller, where they are wound into the meshing point, completing the cutting process.

[0004] However, existing high-speed chopped fiber machines utilize a yarn-swinging mechanism to move the yarn to be cut by pressing it down and winding it into the meshing area of ​​the cutter head and rubber roller to complete the cutting. Sometimes, it is difficult to accurately press the yarn down into the meshing cutting area, resulting in low precision in the yarn pressing position and a success rate of around 95%. Moreover, it can only cut short fibers of relatively short size, such as 3, 4, and 6 mm, and cannot cut large fibers, such as chopped fibers exceeding 12 mm. The reason for this is that if the distance between two adjacent blades on the cutter roller is increased to 12 mm or more, when the previous blade is cutting, the next blade has not yet rotated into the meshing area. Due to the tension at the uncut end of the yarn, the meshing area cannot clamp the cutting end of the yarn. Under the action of tension, the cutting end of the yarn disengages from the meshing area, thus preventing the cutting of yarns larger than 12 mm. Utility Model Content

[0005] In view of the above analysis, the present invention aims to provide a glass fiber online short-cut continuous filament feeding device to solve at least one of the above-mentioned problems existing in the prior art.

[0006] The purpose of this utility model is achieved as follows:

[0007] A glass fiber online chopped continuous filament feeding device includes:

[0008] Rubber rollers;

[0009] The cutting roller has a meshing area with the rubber roller for cutting yarn;

[0010] The rolling pressing mechanism has a pressing roller and a pressing drive mechanism. The pressing roller is rotatably located at one end of the pressing drive mechanism and is situated above the meshing area. The pressing drive mechanism is configured to drive the pressing roller to move toward the circumferential surface of the rubber roller so that the yarn is pressed against the circumferential surface of the rubber roller.

[0011] Furthermore, it also includes a first reversing wheel, which is located below the meshing area of ​​the cutter roller and the rubber roller, and is configured so that when the yarn is being wound, the yarn passes around the first reversing wheel and connects to the drawing mechanism.

[0012] Furthermore, it also includes a yarn guide mechanism configured to guide the yarn to be cut above the rubber roller; the yarn guide mechanism has multiple support points that form a support profile for the yarn, and the circumferential surface of the rubber roller is located inside the support profile.

[0013] Furthermore, the yarn guiding mechanism includes a transition bearing assembly and multiple yarn guiding wheels; the multiple yarn guiding wheels are distributed obliquely above the rubber roller, and the transition bearing assembly is located above the meshing area between the cutter roller and the rubber roller; wherein, the transition bearing assembly includes a bearing frame, the bearing frame is provided with a guide part, the guide part has a smooth convex arc surface, the smooth convex arc surface can guide the yarn to move towards the rubber roller and fall on the circumferential surface of the rubber roller.

[0014] Furthermore, the guide is a cylindrical metal rod, which is mounted on the support frame, and at least a portion of the circumferential surface of the cylindrical metal rod protrudes from the surface of the support frame.

[0015] Furthermore, there are three cylindrical metal rods; the axes of the three cylindrical metal rods are located at the three vertices of the same triangle.

[0016] Furthermore, the cylindrical metal rod includes a first copper rod, a second copper rod, and a third copper rod, with the heights of the first copper rod, the second copper rod, and the third copper rod decreasing sequentially in the vertical direction; the yarn sequentially passes around the first copper rod, the second copper rod, the third copper rod, and the first reversing wheel.

[0017] Furthermore, the other ends of the first copper rod, the second copper rod, and the third copper rod are all provided with conical surfaces; at least one of the first copper rod, the second copper rod, and the third copper rod is provided with a blocking portion at one end, and the blocking portion is away from the circumference of the rubber roller relative to the conical surface.

[0018] Furthermore, it also includes a yarn-pulling mechanism and a second reversing wheel; the yarn-pulling mechanism, the second reversing wheel, and the yarn-guiding mechanism are arranged sequentially along the yarn movement direction; the second reversing wheel is configured to reverse the direction of the yarn; the yarn-pulling mechanism is configured to pull the yarn on the yarn-guiding mechanism onto the circumferential surface of the rubber roller.

[0019] Furthermore, the cutter roller has a cutter disc, on the outer circumference of which several blades are evenly distributed radially, with the interval between the cutting edges of two adjacent blades being 3-24 mm.

[0020] Compared with existing technologies, the glass fiber online chopped continuous yarn feeding device provided by this utility model has a rolling pressing mechanism with a pressure roller and a downward pressing drive mechanism. The downward pressing drive mechanism can drive the pressure roller to move towards the circumference of the rubber roller, so that the yarn is pressed against the circumference of the rubber roller. This arrangement ensures that during the yarn cutting process, the yarn above the meshing area between the cutter roller and the rubber roller is clamped between the rubber roller and the pressure roller. The pressure roller and the rubber roller have a certain clamping force on the yarn. As the yarn is continuously cut, the moving yarn can drive the pressure roller to rotate. Because the yarn above the meshing area is clamped between the rubber roller and the pressure roller, there is no tension in the section of yarn below the clamping position of the pressure roller and the rubber roller, that is, there is no tension at the uncut end of the yarn. Therefore, the meshing area between the cutter roller and the rubber roller can always clamp the cutting end of the yarn, and the cutting end of the yarn will not come out of the meshing area. Therefore, a wider range of yarn lengths can be cut, especially yarns of 12-24mm, ensuring that the cut yarn length meets the requirements. Furthermore, by setting up transition bearing components and multiple guide wheels, the yarn can be precisely pressed down to the meshing and cutting area of ​​the rubber roller and the cutter roller, resulting in higher precision in the yarn pressing position and improving the success rate of loading onto the machine.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] To facilitate understanding of the embodiments of this application, further explanation and description will be provided below with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this application. In the drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0034] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0035] Existing technologies employ a pendulum-driven pressing method for loading the yarn. This involves using a pendulum mechanism to move the yarn to be cut by pressing it down, causing it to be wound into the meshing area of ​​the cutter head and rubber rollers to complete the cutting. Due to the presence of the pendulum mechanism, it is structurally impossible to arrange other similar pressure rollers or pressure wheels, thus making it impossible to cut short fibers larger than 12mm.

[0036] Based on the above problems, a specific embodiment of this utility model is as follows: Figures 1 to 4 , Figures 6 to 7 As shown, a glass fiber online chopped continuous filament feeding device is disclosed, comprising:

[0037] Rubber roller 2; rubber roller 2 is also equipped with a rubber roller cylinder, which is used to drive rubber roller 2 to move closer to or away from cutter roller 1.

[0038] The cutter roller 1 has a meshing area for cutting yarn between it and the rubber roller 2. The yarn (i.e., fiber filament) is cut in the meshing area. The cutter roller 1 has a cutter disc and a cutter roller motor. The cutter roller motor is used to drive the cutter disc to rotate. Several blades are evenly distributed radially on the outer circumference of the cutter disc. The interval between the blades of two adjacent blades is 3-24mm.

[0039] The rolling pressing mechanism 3 has a pressing roller 31 and a pressing drive mechanism 32. The pressing roller 31 is rotatably disposed at one end of the pressing drive mechanism 32 and is located above the meshing area. The pressing drive mechanism 32 is configured to drive the pressing roller 31 to move toward the circumferential surface of the rubber roller 2 so that the yarn is pressed onto the circumferential surface of the rubber roller 2.

[0040] In one alternative embodiment, the rubber roller 2 is further provided with a rubber roller cylinder, which is used to drive the rubber roller 2 closer to or away from the cutter roller 1.

[0041] During the yarn cutting process, the yarn above the meshing area of ​​the cutter roller 1 and the rubber roller 2 is clamped between the rubber roller 2 and the pressure roller 31. The pressure roller 31 and the rubber roller 2 exert a certain clamping force on the yarn. As the yarn is continuously cut, the moving yarn can drive the pressure roller 31 to rotate. Because the yarn above the meshing area is clamped between the rubber roller 2 and the pressure roller 31, there is no tension on the section of yarn below the clamping position of the pressure roller 31 and the rubber roller 2. That is, there is no tension on the uncut end of the yarn. Therefore, the meshing area of ​​the cutter roller 1 and the rubber roller 2 can always clamp the cutting end of the yarn, and the cutting end of the yarn will not come out of the meshing area. Thus, yarns larger than 12mm can be cut.

[0042] In this embodiment, the pressing drive mechanism 32 includes a pressure arm and a drive motor. The pressure roller 31 is rotatably mounted on one end of the pressure arm via a rotating shaft. The drive motor drives the other end of the pressure arm, causing the pressure roller 31 to move towards the circumference of the rubber roller 2 by driving the pressure arm to swing, until the yarn is pressed onto the circumference of the rubber roller 2. It should be noted that the pressure of the pressure roller 31 pressing against the circumference of the rubber roller 2 can be set as needed, and the specific pressure can be set according to actual needs. Since during the second loading, when one or more strands of yarn are being cut short, another strand of yarn needs to be cut short. In this case, the pressure roller 31 cannot be disengaged from the rubber roller, otherwise the yarn will fall off. Therefore, the end face of the pressure roller 31 in this embodiment is provided with a conical surface. The function of this conical surface is that when changing yarn, the pressure roller 31 does not need to be lifted and the pressing action repeated, so that the yarn can be guided into the meshing area between the pressure roller 31 and the rubber roller 2.

[0043] In this embodiment, the glass fiber online chopped continuous yarn feeding device further includes a first reversing wheel 4 and a yarn drawing mechanism 8. The yarn drawing mechanism 8 includes a traction motor and a yarn drawing wheel 81. The traction motor drives the yarn drawing wheel 81 to rotate at a set speed. The first reversing wheel 4 is located below the meshing area of ​​the cutter roller 1 and the rubber roller 2. It is configured such that when the yarn is fed onto the machine, it passes over the first reversing wheel 4 and connects to the yarn drawing mechanism 8. The yarn drawing mechanism 8 is used to draw the fiber filaments to the diameter required by the process. After passing the first reversing wheel 4, the yarn is wound around the yarn drawing wheel 81 of the yarn drawing mechanism 8. The yarn between the yarn drawing wheel 81 and the first reversing wheel 4 of the yarn drawing mechanism 8 is in a horizontal or basically horizontal state.

[0044] In this embodiment, the glass fiber online chopped continuous yarn feeding device also includes a yarn guiding mechanism 5, which is configured to guide the yarn to be cut above the rubber roller 2. The yarn guiding mechanism 5 has multiple support points that form a support contour line for the yarn, and the circumferential surface of the rubber roller 2 is located inside the support contour line. By setting a rolling yarn pressing mechanism 3 and cooperating with a transition bearing component 54 and multiple guide wheels, the yarn can be precisely pressed down to the meshing cutting area of ​​the rubber roller 2 and the cutter roller 1, resulting in higher accuracy in the yarn pressing position.

[0045] In one preferred embodiment, the wire guiding mechanism 5 includes a transition bearing component 54 and a plurality of wire guiding wheels; the plurality of wire guiding wheels are distributed obliquely above the rubber roller 2, and the transition bearing component 54 is located above the meshing area between the cutter roller 1 and the rubber roller 2.

[0046] In one optional embodiment, the yarn guiding mechanism 5 includes three yarn guiding wheels, specifically a first yarn guiding wheel 51, a second yarn guiding wheel 52, and a third yarn guiding wheel 53. These three wheels are rotatably arranged above the rubber roller 2 along an arc-shaped trajectory. "Above the roller 2" means that when facing directly at the circumference of the rubber roller 2, the three yarn guiding wheels are not in the same vertical plane as the rubber roller 2; in this case, the three yarn guiding wheels appear to be positioned above the rubber roller 2.

[0047] In one alternative implementation, such as Figure 5 As shown, the transition support assembly 54 includes a support frame 544, on which a guide portion is provided. The guide portion has a smooth convex arc surface, which can guide the yarn mounted thereon to move towards the rubber roller 2 and fall onto the circumferential surface of the rubber roller 2. Optionally, the guide portion is a cylindrical metal rod, which is mounted on the support frame 544, and at least a portion of the circumferential surface of the cylindrical metal rod protrudes from the surface of the support frame 544.

[0048] For example, there are three cylindrical metal rods; the axes of the three cylindrical metal rods are located at the three vertices of the same triangle. The cylindrical metal rods include a first copper rod 541, a second copper rod 542, and a third copper rod 543, the heights of which decrease sequentially in the vertical direction; the yarn sequentially passes around the first copper rod 541, the second copper rod 542, the third copper rod 543, and the first reversing wheel 4. The yarn can simultaneously contact the first copper rod 541, the second copper rod 542, the third copper rod 543, and the first reversing wheel 4, and the section of yarn between the second copper rod 542, the third copper rod 543, and the first reversing wheel 4 is straight.

[0049] Furthermore, the other ends of the first copper rod 541, the second copper rod 542, and the third copper rod 543 are all provided with conical surfaces. By providing conical surfaces, it is helpful for the yarn to slide smoothly onto the circumference of the rubber roller.

[0050] Furthermore, at least one of the first copper rod 541, the second copper rod 542, and the third copper rod 543 has a blocking portion 5421 at one end. The blocking portion 5421 is located away from the circumferential surface of the rubber roller 2 relative to the conical surface. The blocking portion 5421 is configured to prevent the yarn from slipping out from the side where the blocking portion 5421 is located, so that the yarn can only slide down onto the circumferential surface of the rubber roller 2 from one end of the conical surface. For example, the diameter of the second copper rod 542 is larger than the diameter of the other two copper rods, and the blocking portion 5421 is provided at the end of the second copper rod 542. The size of the blocking portion 5421, for example, its diameter is larger than the diameter of the second copper rod 542.

[0051] In this embodiment, the glass fiber online chopped continuous yarn feeding device further includes a yarn-pulling mechanism 6 and a second reversing wheel 7; the yarn-pulling mechanism 6, the second reversing wheel 7 and the yarn-guiding mechanism 5 are arranged sequentially along the yarn movement direction; the second reversing wheel 7 is configured to reverse the direction of the yarn; the yarn-pulling mechanism 6 is configured to pull the yarn on the yarn-guiding mechanism 5 onto the circumferential surface of the rubber roller 2.

[0052] In this embodiment, the glass fiber online chopped continuous filament feeding device also includes a main frame 9 and a safety locking unit 10. The yarn pulling mechanism 6, the cutter roller 1, the rubber roller 2, the rolling yarn pressing mechanism 3, the second reversing wheel 7, and the yarn pulling mechanism 8 are all mounted on the main frame 9. The yarn guiding mechanism 5 and the first reversing wheel 4 are mounted on the safety locking unit 10. The safety locking unit 10 is connected to the main frame 9 and can at least surround the cutter disc, thereby preventing injury to the operator when the cutter disc cuts the fiber filaments. Optionally, the safety locking unit 10 is made of stainless steel and includes an upper frame and a lower frame, both of which are rotatably connected to the main frame 9 via hinges.

[0053] It should be noted that the relevant structures of the yarn pulling mechanism 6, the second reversing wheel 7, the yarn drawing mechanism 8, the guide wheel, the safety locking unit 10, and the main frame 9 can be achieved using existing technologies.

[0054] Yarn threading process route as follows Figures 6 to 7As shown. During the onboard operation, the operator manually pulls the fiber filament from below the kiln baffle to the yarn pulling mechanism 6. After passing the second reversing wheel 7, the first guide wheel 51, the second guide wheel 52, the third guide wheel 53, and the three copper rods of the transition bearing assembly 54, the fiber filament passes the first guide wheel and is pulled to the yarn drawing mechanism 8. It is then wound onto the low-speed rotating yarn drawing wheel 81. The traction motor speeds up, and when the speed of the yarn drawing wheel 81 increases to the set value, the fiber filament is drawn to the diameter required by the process. The yarn pulling mechanism 6 moves the fiber filament along the first guide wheel 51, the second guide wheel 52, the third guide wheel 53, and the three copper rods to the circumference of the rubber roller 2. Since the rubber roller 2 is lowered and close to the cutter roller 1 after the equipment starts running, and the cutter roller 1 and the rubber roller 2 rotate at the same linear speed, after the yarn pulling action is completed, the yarn slides to the meshing cutting area between the rubber roller 2 and the cutter roller 1 to cut the yarn. After the yarn pulling operation is completed, the pressing drive mechanism 32 starts working, driving the pressure roller 31 to move towards the circumference of the rubber roller 2, so that the yarn is pressed against the circumference of the rubber roller 2. During the yarn cutting process, the yarn located above the meshing area is always clamped between the rubber roller 2 and the pressure roller 31. The first strand of yarn is loaded onto the machine according to the above operation. When changing to the second strand of yarn, the pressure roller 31 does not need to repeat the pressing action. The yarn is guided into the meshing area between the pressure roller 31 and the rubber roller 2 by the conical surface of the end face of the pressure roller 31. This ensures the continuity of yarn cutting.

[0055] Compared with the prior art, the glass fiber online short-cut continuous yarn feeding device provided in this embodiment changes the traditional yarn feeding method by setting a rolling pressing mechanism. The rolling pressing mechanism has a pressing roller and a pressing drive mechanism. The pressing drive mechanism can drive the pressing roller to move towards the circumference of the rubber roller, so that the yarn is pressed against the circumference of the rubber roller. With this setting, during the yarn cutting process, the yarn located above the meshing area of ​​the cutter roller and the rubber roller is clamped between the rubber roller and the pressing roller. The pressing roller and the rubber roller have a certain clamping force on the yarn. As the yarn is continuously cut, the moving yarn can drive the pressing roller to rotate. Because the yarn above the meshing zone is clamped between the rubber roller and the pressure roller, there is no tension on the section of yarn below the clamping position of the pressure roller and rubber roller. That is, there is no tension on the uncut end of the yarn. Therefore, the meshing zone between the cutter roller and the rubber roller can always clamp the cutting end of the yarn, preventing it from slipping out of the meshing zone. This allows for a wider range of yarn lengths to be cut, especially 12-24mm yarn, ensuring the cut yarn meets the required length. Furthermore, by incorporating a transition bearing component and multiple guide rollers, the yarn can be precisely pressed down into the meshing cutting zone of the rubber roller and the cutter roller, resulting in higher precision in the yarn pressing position and improving the success rate of loading the machine.

[0056] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this application. It should be understood that the above description is only a specific embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
