Description

Technical Field

[0001] This invention relates to the field of fiber production technology, specifically to an auxiliary feeding device for pen refill fiber production. Background Technology

[0002] Fibers are substances composed of continuous or discontinuous filaments. In animals and plants, fibers play an important role in maintaining tissues. Fibers have a wide range of uses and can be woven into fine threads, yarn ends, and ropes. They can also be woven into fiber layers in papermaking or felt weaving.

[0003] CN212315173U discloses a fiber spinning and take-up device for antistatic fabrics, including rollers, support columns, base plates, first motors, support plates, mounting cavities, rotating shafts, drums, limiting plates, vertical plates, sliders, wire holes, connecting frames, connecting plates, chutes, discs, guide rollers, guide plates, guide grooves, movable grooves, guide blocks, springs, fixing nuts, gears, bearings, chains, second motors, and guide columns. This device guides and transmits fiber filaments, providing a buffering effect and protection during yarn transmission. However, while it guides the winding of the filaments, the direct contact between the filaments and the guide causes significant relative friction, increasing wear. Furthermore, traditional guiding devices only provide guidance, so filament breakage goes undetected, and there are no alarm devices. Idle operation during production leads to resource waste. Therefore, we propose an auxiliary feeding device for pen refill fiber production to address these problems. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary feeding device for pen refill fiber production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary feeding device for pen refill fiber production, comprising,

[0006] The transmission seat has a pair of straight plates on its top, on which a transmission frame and a stretching frame are installed. A guide shaft is installed on one side of the transmission seat. Multiple transmission rings are provided inside the transmission frame. A carding plate with a corresponding position is provided on the top of the transmission ring. The transmission ring and the carding plate cooperate to clean the fiber filaments. Multiple snap-fit ​​plates are installed on the stretching frame. A guide frame is installed at the bottom of the snap-fit ​​plate.

[0007] The guide frame consists of a pair of bent metal shafts. A snap-fit ​​bracket is movably mounted inside the guide frame, and a guide plate is installed inside the snap-fit ​​bracket. A connecting plate is installed at one end of the guide frame, and a reset rod with the snap-fit ​​bracket mounted on the top of the connecting plate is provided. The snap-fit ​​bracket, in conjunction with the guide plate, is used for fiber stretching and transmission. When fiber feeding is required, the feeding bobbin can be snapped onto one side of the snap-fit ​​bracket, allowing the fiber to pass through the guide ring, transmission frame, and stretching frame respectively. Oiling of the fiber can be applied during transmission to reduce wear. The stretching frame can also stretch the fiber during transmission. When a thread breakage occurs or tapping is completed, the reset rod pushes the snap-fit ​​bracket against the stop block. With the cooperation of a pressure sensor and an audible and visual alarm, the operator is alerted to make adjustments or replacements, reducing the possibility of the equipment running idle during use.

[0008] Preferably, a fixed shaft is installed inside the transmission frame, and multiple fixed rings are installed on the surface of the fixed shaft. The transmission rings are rotatably disposed on one side of the fixed rings. A servo motor for controlling the rotation of the transmission rings is installed inside the fixed rings, and a signal receiver is installed inside the servo motors.

[0009] The transmission ring has an annular groove, and multiple transmission top blocks are installed at both ends of the transmission ring. Under the action of the signal generator and signal receiver, the servo motor is stopped, which facilitates the operator to perform subsequent wiring processing and reduces the time wasted by manual wiring.

[0010] Preferably, the top of the transmission frame is equipped with multiple connecting end blocks, the bottom of the connecting end blocks is provided with positioning grooves, the top of the connecting end blocks is equipped with connecting frames, the connecting frames are inserted with threaded shafts, the threaded shafts pass through the bottom of the connecting end blocks and are rotatably mounted with air pressure plates, the carding plate is installed at the bottom of the air pressure plates, the air pressure plates are fitted with movable locking blocks, the movable locking blocks are equipped with rectangular frames at both ends, and the rectangular frames abut against the bottom of the transmission frame, the movable locking blocks cooperate with the transmission top block to push and squeeze the air pressure plates to drive the carding plates to move, the carding plates are made of sponge material, which can intermittently squeeze the fiber filaments, playing the role of cleaning and lubricating.

[0011] Preferably, the carding plate has a circular groove, and an elastic rod is inserted inside the circular groove. The surface of the elastic rod has multiple annular grooves, and a sponge ring for absorbing lubricant is inserted inside the annular grooves. Through the cooperation of the elastic rod with the cam of the transmission top block, the sponge ring is driven to generate a pulsating squeezing effect. Under the condition of constant transmission speed, the lubricant can be replenished within a fixed time, ensuring that the oil content of the carding plate is stable within a certain saturation range, avoiding the situation of excessive lubrication in traditional drip lubrication.

[0012] Preferably, a metal shaft is installed on the top of the connecting plate, the reset rod is movably sleeved on the top of the metal shaft, a recycling box is installed on the top surface of the reset rod, and the snap-fit ​​piece is installed on the top of the recycling box;

[0013] The snap-fit ​​piece has a through groove, and a squeezing tube is snapped inside the through groove. The squeezing tube has a "C" shaped cross section and multiple separation grooves. The C-shaped squeezing tube, together with the grid separation insert, forms a gradient filtering structure.

[0014] Preferably, the recycling box is equipped with a separation plate, the separation plate has a mesh plate inside, and the outer wall of the separation plate is fitted with an arc-shaped pad that abuts against the snap-fit ​​piece. Excess lubricant enters the recycling box through the separation groove, and after being filtered by the mesh plate, excess dirt is removed, allowing the sponge ring to be directly soaked and oiled.

[0015] Preferably, a limiting rod is installed on the top of the clip frame, and a rectangular block connected to the guide wire is installed on the top of the limiting rod. An elastic band is clamped between the rectangular block and the side walls at both ends of the recycling box. A fixing frame is installed on the elastic band, and a conduction ring is rotatably provided on the fixing frame, which can provide auxiliary support for the fiber and provide a certain elastic compensation for the fiber during the transmission process.

[0016] Preferably, a movable frame is fitted on the side wall of the connecting plate. The movable frame is U-shaped. A pair of stop blocks are installed on the top of the inner wall of the movable frame. The stop blocks are provided with inclined surfaces on which pressure-sensitive sensors are installed. The position of the stop blocks corresponds to the snap-fit ​​piece.

[0017] The top of the movable frame is equipped with an audible and visual alarm electrically connected to a pressure-sensitive sensor. The movable frame is also equipped with a signal generator connected to the audible and visual alarm by wire. Through a dual triggering mechanism of pressure-sensitive sensor and mechanical linkage: when the wire breaks, the reset rod pushes the locking piece to contact the stop block, triggering the audible and visual alarm with the help of the pressure-sensitive sensor and sending a stop signal to the servo motor. The signal can also be transmitted to the transmission loop, reducing the occurrence of idling and reducing downtime.

[0018] Preferably, a plurality of guide rings are mounted on the surface of the guide shaft, and a dust-collecting plate is mounted on the inner wall of the guide ring for cleaning the fiber filaments and reducing dust residue.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention achieves uniform coating of lubricant on the fiber surface by dynamically adjusting the transmission ring speed with the fiber linear speed through a servo motor, combined with intermittent squeezing and lubrication by a sponge carding plate driven by a pneumatic plate, which can reduce wear during transmission.

[0022] 2. This invention uses a dual-trigger mechanism of pressure-sensitive sensor and mechanical linkage. When the wire breaks, the reset rod pushes the locking piece to contact the stop block. The pressure-sensitive sensor triggers an audible and visual alarm and sends a stop signal to the servo motor via signal transmission, reducing the occurrence of idling and downtime.

[0023] 3. This invention uses a C-shaped extrusion tube in conjunction with a grid separation plate to form a gradient filtration structure, which can allow excess lubricant to enter the recovery box through the separation tank. After being filtered by the grid plate, excess dirt is removed, and the sponge ring can be directly soaked and oiled.

[0024] 4. This invention uses the elastic insert rod to cooperate with the cam of the transmission top block to drive the sponge ring to generate a pulsating squeezing effect. Under the condition of constant transmission speed, it can replenish the lubricant within a fixed time, ensuring that the oil content of the carding plate is stable within a certain saturation range, and avoiding the excessive lubrication of traditional drip-type lubrication.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] See also Figures 1-8 This invention provides a technical solution: an auxiliary feeding device for pen refill fiber production, comprising,

[0036] The transmission seat 1 has a pair of straight plates on its top, on which a transmission frame 3 and a stretching frame 4 are installed. A guide shaft 2 is installed on one side of the transmission seat 1. Multiple transmission rings 35 are provided inside the transmission frame 3. A carding plate 37 with a corresponding position is provided on the top of the transmission ring 35. The transmission ring 35 and the carding plate 37 cooperate to clean the fiber. Multiple snap-fit ​​plates 41 are installed on the stretching frame 4. A guide frame 411 is installed at the bottom of the snap-fit ​​plate 41.

[0037] The guide frame 411 consists of a pair of bent metal shafts. A snap-fit ​​bracket 42 is movably mounted inside the guide frame 411, and a guide plate 431 is installed inside the snap-fit ​​bracket 42. A connecting plate 44 is installed at one end of the guide frame 411. A reset rod 45 with a snap-fit ​​piece 48 mounted on the top of the connecting plate 44 is provided. The snap-fit ​​piece 48, in conjunction with the guide plate 431, is used for fiber stretching and transmission. When fiber feeding is required, the feeding bobbin can be snapped onto one side of the snap-fit ​​bracket 11, allowing the fibers to pass through the guide plate. The wire ring 21, the transmission frame 3, and the tensioning frame 4 can oil the fiber filaments during transmission, reducing wear. During transmission, the tensioning frame 4 can stretch the fiber filaments. When a wire breaks or after tapping is completed, the reset rod 45 can push the locking piece 48 to abut against the stop block 49. With the cooperation of the pressure sensor and the audible and visual alarm 491, the operator can be reminded to make adjustments or replacements, reducing the occurrence of idling during equipment use.

[0038] like Figure 3 As shown, in order to ensure the stability of fiber transmission and reduce the occurrence of deviation during transmission, a fixed shaft 33 is installed inside the transmission frame 3. Multiple fixed rings 34 are installed on the surface of the fixed shaft 33. The transmission ring 35 is rotatably set on one side of the fixed ring 34. A servo motor for controlling the rotation of the transmission ring 35 is installed inside the fixed ring 34. A signal receiver is installed inside the servo motor. With the help of the servo motor, the transmission speed of the transmission ring 35 can be controlled to keep up with the linear speed of the fiber, which can reduce the wear of the fiber during transmission.

[0039] The transmission ring 35 has an annular groove, and multiple transmission top blocks 351 are installed at both ends of the transmission ring 35. During the transmission process, the transmission top blocks 351 can intermittently push the movable card block 361 to move, thus playing a driving role.

[0040] like Figure 3 and Figure 4As shown, for oiling the fiber surface, the top of the transmission frame 3 is equipped with multiple connecting end blocks 31. The bottom of each connecting end block 31 has a positioning groove. A connecting frame 32 is installed on top of the connecting end block 31. A threaded shaft 321 is inserted inside the connecting frame 32. The threaded shaft 321 passes through the bottom of the connecting end block 31 and is rotatably mounted on a pneumatic plate 36. A carding plate 37 is installed at the bottom of the pneumatic plate 36. A movable locking block 361 is fitted onto the pneumatic plate 36. Rectangular frames are installed at both ends of the movable locking block 361, and these rectangular frames abut against the bottom of the transmission frame 3. The movable locking block 361 cooperates with... The drive top block 351 pushes and squeezes the air pressure plate 36, which in turn moves the carding plate 37. The carding plate 37 is made of sponge. As the movable locking block 361 moves with the drive top block 351, it can squeeze the gap of the air pressure plate 36. The change in air pressure causes the bottom of the air pressure plate 36 to deform, thus pressing the carding plate 37 against the inside of the annular groove. This can assist in cleaning the surface of the fiber. During the squeezing and cleaning process, lubricant can also be evenly applied to the surface of the fiber, which can effectively reduce the wear generated during the fiber transmission process.

[0041] like Figure 4 As shown, in order to ensure that the lubricant is applied evenly, the carding plate 37 has a circular groove, and an elastic rod 371 is inserted inside the circular groove. The surface of the elastic rod 371 has multiple annular grooves, and a sponge ring for absorbing lubricant is inserted inside the annular groove. As the movable locking block 361 reciprocates, it can squeeze the two ends of the elastic rod 371, which can squeeze the lubricant inside the sponge ring into the carding block for auxiliary replenishment. The elastic rod 371 can be disassembled and replenished with lubricant independently.

[0042] like Figure 6 and Figure 7 As shown, in order to reduce dust and other adhering substances during fiber transmission, a metal shaft is installed on the top of the connecting plate 44, and the reset rod 45 is movably sleeved on the top of the metal shaft. A recycling box 46 is installed on the top of the surface of the reset rod 45, and a snap-fit ​​piece 48 is installed on the top of the recycling box 46. During transmission, the fiber can push the reset rod 45 to move away from the stop block 49, which can stretch the fiber and ensure the stability of transmission.

[0043] The snap-fit ​​piece 48 has a through groove, and a squeezing tube 481 is snapped inside the through groove. The squeezing tube 481 has a "C" shaped cross section and multiple separation grooves. The fiber can be snapped inside the squeezing tube 481, and excess lubricant on the surface of the fiber can be discharged along the separation grooves on the squeezing tube 481 and fall into the recycling box 46 for easy subsequent unified processing.

[0044] like Figure 6As shown, a separation plate 461 is inserted inside the recycling box 46. The separation plate 461 has a mesh plate inside, which can separate the lubricant and facilitate the subsequent recycling of excess lubricant. An arc-shaped pad is installed on the outer wall of the separation plate 461, which abuts against the snap-fit ​​piece 48. During the fiber transmission process, the snap-fit ​​piece 48 can be squeezed, and the snap-fit ​​piece 48 can be pressed down to squeeze the arc-shaped pad, which can play a buffering role.

[0045] like Figure 8 As shown, a limiting rod 43 is installed on the top of the clip frame 42. A rectangular block connected to the guide wire plate 431 is installed on the top of the limiting rod 43. An elastic band 47 is clamped between the rectangular block and the side walls at both ends of the recycling box 46. A fixing frame is installed on the elastic band 47, and a transmission ring 471 is rotatably installed on the fixing frame. During the transmission process, the transmission ring 471 can play a supporting role and play a certain elasticity compensation to prevent unexpected situations of deviation during the transmission process.

[0046] like Figure 8 As shown, in order to reduce the situation where the equipment runs idle due to operator fatigue before it is observed in the event of a wire break, a movable frame 441 is installed on the side wall of the connecting plate 44. The movable frame 441 is U-shaped, and a pair of stop blocks 49 are installed on the top of the inner wall of the movable frame 441. The stop blocks 49 are provided with inclined surfaces on which pressure-sensitive sensors are installed, and the positions of the stop blocks 49 correspond to the snap-fit ​​piece 48.

[0047] The top of the movable frame 441 is equipped with an audible and visual alarm 491 electrically connected to a pressure-sensitive sensor. The movable frame 441 is also equipped with a signal generator connected to the wire of the audible and visual alarm 491. When the fiber filament transmission is completed or a break occurs, the squeezing force on the top of the reset plug 45 disappears, allowing it to quickly reset. The snap-fit ​​piece 48 can squeeze between the snap-fit ​​piece 48 and the stop pressure block 49, which can trigger the pressure-sensitive sensor, thereby controlling the operation of the audible and visual alarm 491 to serve as a reminder. In the event of an external accidental break, the stop pressure block 49 can interact with the snap-fit ​​piece 48 and the squeeze tube 481 to lock the fiber filament inside the squeeze tube 481. Under the action of the signal generator and the signal receiver, the servo motor stops, making it easier for the operator to perform subsequent wiring processing and reducing the time wasted on manual wiring.

[0048] like Figure 2 As shown, multiple guide rings 21 are mounted on the surface of the guide shaft 2, and a dust suction plate 22 is mounted on the inner wall of the guide ring 21 for cleaning the fiber filaments and reducing dust residue.

[0049] like Figure 1 As shown, a snap-fit ​​seat 11 is installed at the bottom of the transmission seat 1. A rotating shaft is installed at one end of the snap-fit ​​seat 11 to snap the feeding yarn tube and play the role of feeding and transmitting materials.

[0050] Working principle: First, when it is necessary to feed the fiber yarn, the feeding yarn bobbin can be clamped on one side of the clamping seat 11. The fiber yarn passes through the guide ring 21, the transmission frame 3 and the stretching frame 4 respectively. During the transmission process, the fiber yarn can be oiled to reduce wear. During the transmission process, the fiber yarn can be stretched with the help of the stretching frame 4. When a yarn breakage occurs or the tapping is completed, the reset rod 45 can push the clamping piece 48 to abut against the stop block 49. With the cooperation of the pressure sensor and the audible and visual alarm 491, the operator is reminded to make adjustments and replacements, reducing the occurrence of idling during the use of the equipment. As the fiber yarn passes through the guide ring 21 during the transmission process, the dust suction plate 22 can clean the debris on the surface of the fiber yarn to reduce the residue.

[0051] Then, during the fiber transmission process, the fiber passes through the transmission ring 35, and the transmission ring 35 can maintain the same linear speed as the fiber, which can reduce the wear on the surface of the fiber during transmission. During the movement of the transmission ring 35, the cooperation between the transmission top block 351 and the rectangular frame can cause the movable block 361 to reciprocate, causing the bottom of the air pressure plate 36 to protrude and deform, which can push the carding plate 37 against the surface of the transmission ring 35. The lubricant adsorbed on the surface of the elastic rod 371 can be evenly distributed inside the sponge carding plate 37 under capillary action. When the fiber surface is squeezed, the surface is evenly oiled. The carding plate 37 can also play a certain auxiliary cleaning role, reducing the amount of lint and dust residue on the surface of the fiber.

[0052] Finally, when the fiber passes through the stretching frame 4, it can be secured inside the extrusion tube 481 inside the guide plate 431 and the clamping plate 48. During the transmission process, the fiber can push the reset rod 45 to move away from the stop block 49, thus stretching the fiber. During the transmission process, the conduction ring 471 can provide support and elasticity compensation. Excess lubricant on the surface of the fiber can be discharged along the separation groove on the extrusion tube 481 and fall into the recycling box 46 for subsequent unified processing. In the event of a wire breakage, the pressure on the top of the reset pin 45 disappears, allowing it to quickly reset. The snap-fit ​​piece 48 can press against the stop block 49, triggering the pressure sensor and controlling the operation of the audible and visual alarm 491 to provide a warning. In the event of an external accidental wire breakage, the stop block 49 can interact with the snap-fit ​​piece 48 and the extrusion tube 481, securing the fiber filament inside the extrusion tube 481. Under the action of the signal generator and signal receiver, the servo motor stops, facilitating subsequent wiring by the operator and reducing the time wasted on manual wire threading.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
