Description
Technical Field
[0001] This utility model relates to the technical field of silk reeling equipment in silk production engineering, specifically to an openable and movable monofilament deburring device. Background Technology
[0002] Silk reeling is the process of extracting silk threads from silkworm cocoons after boiling them. Specifically, the process involves soaking several boiled silkworm cocoons in reeling broth, separating the silk threads from the cocoon layer through friction and pulling, and combining multiple single filaments into a single strand of raw silk to meet specific quality and specification requirements.
[0003] In existing silk reeling equipment, during normal operation, raw silk passes through the thread-receiving wing and the thread-collecting orifice, moving upwards at the reeling linear speed. When a single filament in a cocoon becomes rough, the diameter of the entire strand of raw silk increases at that point. When it tries to pass through the thread-collecting orifice, the roughness compresses against the orifice wall, increasing the resistance as the raw silk passes through. The thread-collecting device detects this and, via an actuator, stops the reeling process. The roughness is then removed manually before reeling resumes. This process typically relies on manual operation, resulting in low production efficiency, especially when processing large quantities of cocoons, where frequent manual intervention increases labor intensity and time costs. Summary of the Invention
[0004] The purpose of this invention is to ensure that when a single filament of a cocoon becomes rough, the reeling process continues while the roughness is removed, thus achieving uninterrupted reeling. During the reeling process, the roughness is continuously blocked by the de-roughening device, and the blocked roughness accumulates in the slit, blocking the slit and preventing normal reeling. By designing the de-roughening device to be openable and closable, the blockage in the slit can be discharged, improving work efficiency.
[0005] To achieve the above objectives, an openable and movable single-wire deburring device is designed, comprising an upper multi-grid plate and a lower multi-grid plate, connected by a hinge shaft. The upper and lower multi-grid plates each have several cooperating upper and lower grid plates. The lower part of the upper grid plate is L-shaped, with its inner top surface engaging with the upper surface of the lower grid plate. A gap is left between the outer side of the L-shaped upper grid plate and the side of an adjacent lower grid plate, forming a working slit. The lower multi-grid plate has at least one positioning slot. The hinge shaft has a positioning plate that is linked to the upper multi-grid plate. The positioning plate has two tapered pins. When the tapered pins engage with the positioning slot, they restrict the axial and radial movement of the upper and lower multi-grid plates.
[0006] Preferably, the multi-gate upper plate includes an upper plate body and a plurality of upper gate plates, and the multi-gate lower plate includes a lower plate body and a plurality of lower gate plates. The upper plate body and the lower plate body are respectively rotatably connected to the hinge shaft. The lower plate body is inclined and forms an angle with the plurality of lower gate plates so that after the upper gate plates and the lower gate plates are engaged, a cavity is left between the upper plate body and the lower plate body.
[0007] Preferably, the inner top surface of the L-shaped upper grid plate cooperates with the upper surface of the lower grid plate to restrict the radial movement of the upper and lower grid plates, and the positioning plate cooperates with the positioning slot to restrict the axial movement of the upper and lower grid plates.
[0008] Preferably, the lower multi-grid sheet is provided with a mounting base on its rear side, the mounting base is provided with a positioning hook, the positioning hook is provided with a fixing bracket that is matched with it, and the fixing bracket is provided with a hooked spring plate.
[0009] Preferably, the upper and lower multi-grid plates are stacked to form a silk passage, and the upper and lower multi-grid plates are stacked to form a multi-serrated silk passage. The two sides of the upper and lower grid plates are straight surfaces, which are used to directly hook the silk into the working slit. The direction of the slit is towards the center of the de-roughening device. The upper or lower grid plate and the working slit form a U-shape. The opening of the U-shape is used to capture the cocoon silk after adding cocoons.
[0010] Preferably, the width of the working slit is greater than the diameter of the single filament.
[0011] Preferably, the surfaces of the upper and lower multi-gate sheets are coated with Teflon; a wire stopper is installed below the lower multi-gate sheet.
[0012] Preferably, the positioning plate is provided with a wrench, and a miniature deburring cylinder is installed on the wrench.
[0013] Preferably, the opening and closing movable monofilament deburring device removes roughness from individual filaments before the multiple strands of filaments are gathered and bound together.
[0014] Preferably, the movable monofilament deburring device is installed below the thread receiving wing.
[0015] Compared with the prior art, the advantages of this utility model are:
[0016] 1. Improve production efficiency: By automatically cutting and removing the filaments containing roughness, the time for manual inspection and processing is reduced, allowing the silk reeling process to be carried out continuously, thereby improving production efficiency.
[0017] 2. Easy to clean and maintain: When the upper and lower multi-grid plates are opened, the working surface is open, which facilitates cleaning and maintenance and ensures long-term effective operation of the equipment.
[0018] 3. Reduced manual intervention: Traditional silk reeling methods require workers to frequently stop reeling to remove roughness, while the design of this utility model can automatically handle roughness, significantly reducing the need for manual operation and lowering labor intensity.
[0019] 4. Intelligent and automated: The opening and closing monofilament de-roughening device and automatic replenishment mechanism equipped in this utility model realize the intelligentization of the silk reeling process, and can automatically adjust and optimize the operation mode according to the actual production situation.

[0030] To make the purpose, principle and structure of this utility model clearer, the following description is provided in conjunction with the accompanying drawings and specific embodiments.
[0031] See Figure 1 , Figure 2 This embodiment provides an arc-shaped, openable, movable monofilament deburring device, comprising an upper multi-grid plate and a lower multi-grid plate. The upper multi-grid plate includes an upper plate body and several upper grid plates 1, and the lower multi-grid plate includes a lower plate body and several lower grid plates 2. The lower multi-grid plate is provided with several open parallel elongated slots 4. The upper and lower multi-grid plates each contain several cooperating upper grid plates 1 and lower grid plates 2. The lower part of the upper grid plate 1 has an L-shaped structure, and the inner top surface of the L-shaped upper grid plate 1 and the upper surface of the lower grid plate 2 are matched. After being stacked, the outer bottom surface of the L-shaped upper grid plate 1 is... A gap of approximately 0.03~0.05mm is left between the adjacent lower grid plate 2 and its side, forming a working slit 9. The width of the working slit 9 is slightly larger than the size of the monofilament 11, forming a wrapping state with the lower grid plate 2 around the monofilament 11. This creates an open channel for continuous detection of the monofilament 11 and for blocking, squeezing, and breaking roughness. The upper and lower multi-grid plates can be configured as single-groove or double-groove plates depending on the actual situation. The main purpose is to remove roughness from the monofilament 11 before the multi-strand filaments are gathered and bound together. The surfaces of the upper and lower multi-grid plates are coated with Teflon. The upper and lower multi-grid plates form a multi-toothed silk passage channel. At the leading edge of the multi-toothed silk passage channel, the teeth can be arranged in an arc shape to better distribute the silk from the cocoon into each channel.
[0032] The upper body of the multi-grid upper plate and the lower body of the multi-grid lower plate are connected by a hinge shaft 3, allowing the upper grid plate 1 and the lower grid plate 2 to overlap and separate in the direction of the overlapping surface. When the upper grid plate 1 and the lower grid plate 2 separate, a relatively wide gap between the grid teeth will appear, which can remove the obstructed roughness. A positioning slot 6 is provided on the left side of the multi-grid lower plate, and a positioning piece 7 linked to the multi-grid upper plate is provided on the left side of the hinge shaft 3. A cylindrical wrench 5 is fixedly connected to the left side of the positioning piece 7. The lower end of the positioning piece 7 is set with a tapered structure. The positioning piece 7 and the positioning slot 6 are set to cooperate with each other. When the upper grid plate 1 and the lower grid plate 2 are closed, the positioning piece 7 is inserted into the positioning slot 6. Because the lower end of the positioning piece 7 has a certain taper, the gap is eliminated after the positioning piece 7 and the positioning slot 6 are connected, ensuring that the wire-passing roughness-blocking gap distance between the upper grid plate 1 and the lower grid plate 2 remains consistent when they are closed, which is used to limit the axial movement between the multi-grid upper plate and the multi-grid lower plate.
[0033] See Figure 3 , Figure 4This embodiment provides a toothed, openable, movable monofilament de-roughening device. Based on an arc-shaped, openable, movable monofilament de-roughening device, the multiple teeth of the upper grid plate 1 and lower grid plate 2 are changed to a serrated shape, so that the upper grid plate 1 and lower grid plate 2, when stacked, form a multi-serrated silk passage channel. Furthermore, the positioning plate is designed with a two-dimensional tapered pin. The tapered pin on the positioning plate, after engaging with the positioning slot, is used to restrict the axial and radial movement of the upper and lower grid plates. The two sides of the serrated upper grid plate 1 and lower grid plate 2 are straight, used to directly hook the silk into the working slit, with its direction pointing towards the center of the de-roughening device. The upper grid plate 1 or lower grid plate 2 forms a U-shape with the working slit, and the opening of the U-shape is used to capture the cocoon silk after cocoon filling.
[0034] See Figure 5 During reeling, the monofilament 11 enters the working slit 9 perpendicularly from the opening and moves in the direction of the reeling speed V. When the monofilament 11 becomes rough, indicating that its diameter is too large and exceeds the slit width, its reeling movement is hindered, and it cannot pass through the gap of the working slit 9. When the resistance exceeds the breaking strength of the monofilament 11, it is cut off, resulting in a slack cocoon, thus completing the descratching process of the monofilament 11. When the upper grid plate 1 and the lower grid plate 2 are closed, the working slit is in an effective working state. When open, the working surface that forms the contact between the working slit and the monofilament moves to the open space along with the upper grid plate 1 and the lower grid plate 2. This facilitates cleaning and maintenance of the working surface, ensuring the effective process performance of the monofilament descratcher when it is closed.
[0035] See Figure 6 , Figure 7 In actual production, roughness includes two types: large roughness 8 and small roughness 10. Figure 6 This is the state of the large roughness 8 after it has been stored outside the roughening device. Figure 7 This represents the state in which the small roughness 10 is blocked within the channel.
[0036] See Figure 8 The lower sheet body of the multi-grid lower sheet is inclined, forming an angle with several lower grid sheets 2. After the upper grid sheet 1 and the lower grid sheet 2 are stacked, a cavity is left between the upper sheet body and the lower sheet body. A cylindrical connecting rod 12 is fixedly connected to the wrench 5. A miniature deburring cylinder 13 is set at the lower side of the connecting rod 12. The miniature deburring cylinder 13 is connected to the controller. Under the control of the controller, the cylinder 13 performs high-frequency reciprocating motion, pushing the wrench 5 at regular intervals to quickly remove the roughness stuck in the channel, so that the reeling can be carried out continuously, providing support for fully automatic reeling. A wire stopper 14 is installed in the lower middle part of the multi-grid lower sheet, specifically located slightly in front of the projection of the grid root of the multi-grid lower sheet, to prevent the wire from reaching the root of the grid. A mounting base is set at the lower rear end of the multi-grid lower sheet.
[0037] See Figure 9 The opening and closing movable monofilament de-roughening device provided in this embodiment has a mounting base 17 with a positioning hook 15 on its rear side. When the de-roughening device is flipped upwards, the spring plate 16 engages with the positioning hook 15. The positioning hook 15 cooperates with the hooked spring plate of the fixed bracket, so that the de-roughening device is in a horizontal state and performs the de-roughening function. When rewinding, the de-roughening device will block the through hole when drawing the thread from the rewinding groove, causing inconvenience to the operation. At this time, the de-roughening device is folded downwards to expose the through hole. After drawing the thread, the de-roughening device is flipped upwards again. At this time, the spring plate 16 hooks the positioning hook 15, so that the de-roughening device can be folded downwards when drawing the thread, making the operation more convenient.
[0038] The movable monofilament roughening device provided in this embodiment is installed below the reeling wing. Its function is to prevent roughening of a monofilament 11 in a cocoon when the diameter of the monofilament 11 is too large, exceeding the width of the working slit 9 of the movable monofilament roughening device. In this case, the movement of the monofilament 11 during silk reeling is obstructed. Figure 4 As shown, monofilament 11 cannot pass through the working slit 9. When the resistance exceeds the breaking strength of monofilament 11, it is cut, resulting in a cocoon falling out of the raw silk. This completes the process of removing roughness from monofilament 11. Meanwhile, the small slit continues to rotate, and reeling continues without stopping, improving production efficiency. If a cocoon is missing from the raw silk, the cocoon feeder in the automatic reeling machine's detection and execution mechanism will automatically replenish the missing cocoon as needed, ensuring normal reeling according to specifications.
[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and novel concept of this utility model, should be included within the protection scope of this utility model.
