Description

Technical Field

[0001] This invention relates to the field of drawing frame canister filling technology, specifically to a novel drawing frame canister filling mechanism and its control method. Background Technology

[0002] The drawing frame is used in the spinning process to combine, draft, and mix multiple carded slivers to produce slivers with higher uniformity and more stable structure. During the continuous operation of the drawing frame, the replenishment of sliver cans is one of the core links to ensure production continuity. The efficiency, stability, and degree of automation of the replenishment operation directly affect the capacity, product quality, and production cost of the entire spinning production line.

[0003] The core actuator of the existing bobbin replenishing mechanism is a rodless cylinder. During use, due to the severe dust and fly waste in the air of cotton mills, the air inlet and magnet structure of the rodless cylinder are often blocked, which greatly reduces the working performance of the rodless cylinder and shortens its service life. This results in the bobbin replenishing mechanism needing to be stopped frequently for maintenance, which cannot meet the needs of continuous production of the drawing frame. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a novel replenishing mechanism for a drawing frame and its control method, which solves the problem that the rodless cylinder of the existing replenishing mechanism often gets clogged during use, reducing the working performance of the rodless cylinder and causing the replenishing mechanism to require frequent shutdowns for maintenance.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a novel sliver filling mechanism for a drawing frame, comprising a T-stand, a motor fixedly connected inside the T-stand, a transmission assembly provided at the output end of the motor, a clamping plate fixedly connected outside the transmission assembly, a slider fixedly connected outside the clamping plate, and a push rod fixedly connected outside the other side of the slider.

[0006] Preferably, the transmission assembly includes a driven wheel, the interior of which is located at the output end of the motor, a belt is fitted around the driven wheel, an adjusting screw is installed on the exterior of the driven wheel, and a fixed base is fixedly connected to the exterior of the T-stage.

[0007] Preferably, a positioning seat is fixedly connected to the outside of the T-stage, a sliding shaft is installed inside the positioning seat, a nylon sleeve is installed inside the slider, the inside of the slider is slidably connected to the outside of the sliding shaft, and one side of the nylon sleeve is attached to the outside of the sliding shaft.

[0008] Preferably, the T-stage is externally fixedly connected with a limiting block for blocking the slider.

[0009] Preferably, slots are provided on both sides of the slider, cleaning plates are attached to both sides of the nylon sleeve, a cleaning sleeve is installed inside the cleaning plate, an insert plate is fixedly connected to one side of the cleaning plate, a fixing hole is provided inside the insert plate, a housing is fixedly connected to the outside of the slider, a pushing component is provided inside the housing, and the outside of the insert plate is snapped into the inside of the slot.

[0010] Preferably, the pushing component includes a spring, one end of which is fixedly connected to the inside of the housing, a fixed post passing through the inside of the spring, and a push plate fixedly connected to the outside of the fixed post.

[0011] Preferably, the push plate is externally slidably connected to the inside of the spring, the fixed post is externally slidably connected to the inside of the spring, one side of the push plate is externally fixedly connected to the other end of the spring, and one end of the fixed post is engaged with the inside of the fixed hole.

[0012] Preferably, the cleaning sleeve is one of polyester fiber felt, nylon felt, soft polyurethane sleeve, and nylon fiber.

[0013] Preferably, the outer shell has a retaining plate inside, and a roller is fixedly connected to the upper surface of the retaining plate. Both ends of the T-stage are fixedly connected to detection photoelectric sensors. The T-stage has a guide rail inside, and the roller is slidably connected to the inside of the guide rail.

[0014] Preferably, a control method for a novel replenishing mechanism of a drawing frame includes the following steps: S1: Standby monitoring. The replenishment mechanism is in the initial standby state. The detection photoelectric sensors at both ends of the T-stage monitor the initial position of the slider in real time. At the same time, the main unit detection module continuously detects the full status of the cotton swabs in the main unit. When the cotton swabs in the main unit are full and pushed out, the main unit sends a replenishment start signal to the motor controller. S2: Replenishment cylinder drive. After receiving the replenishment cylinder start signal, the motor controller controls the motor to rotate. The motor drives the belt to move synchronously through the transmission component. The belt drives the slider to slide along the sliding axis towards the main machine through the clamp plate. The slider drives the push cylinder rod to move synchronously, pushing the cotton sliver to be replenished into the main machine. S3: Position detection. When the pusher rod pushes the cotton swab to be replenished to the preset position in the host, the host detection module detects that the cotton swab is in position and sends a reset signal to the motor controller. At the same time, during the movement of the slider, the roller on its outer plate slides along the guide rail to ensure smooth movement. S4: Mechanism reset. After receiving the reset signal, the motor controller controls the motor to rotate in the opposite direction. Through the transmission component, the slider and push cylinder rod are driven to retract along the slide shaft to the initial position. During the retraction process, the nylon sleeve inside the slider and the cleaning sleeve on the cleaning plate simultaneously rub and clean the surface of the slide shaft to remove dust and fly shavings. S5: Stop and standby. When the photoelectric sensor at the initial end of the T-stage detects that the slider has returned to its initial position, it sends a stop signal to the motor controller. The motor controller then controls the motor to stop rotating, and the replenishing mechanism returns to its initial standby state, waiting for the next replenishing signal.

[0015] This invention provides a novel replenishing mechanism for a drawing frame and its control method. It has the following beneficial effects: 1. This invention controls the rotation of a motor through a motor controller. The motor drives the driven wheel to rotate, and the driven wheel drives the belt to move synchronously. The belt drives the slider to slide along the sliding axis towards the main machine through the clamp plate, and synchronously drives the push rod to move. The push rod pushes the cotton sliver to be replenished into the main machine, thereby avoiding frequent shutdowns for maintenance of the replenishment mechanism and improving the convenience of replenishment.

[0016] 2. This invention cleans by having the nylon sleeve and cleaning sleeve move with the slider and generate relative motion with the surface of the sliding shaft. When the cleaning plate needs to be disassembled, the fixing post is first pulled outward to a certain distance so that one end of the fixing post disengages from the fixing hole. Then, the insert plate is pulled outward, and the insert plate drives the cleaning plate and cleaning sleeve to separate from the slot of the slider. It can be manually cleaned by being clamped to the sliding shaft by external force. This can prevent dust and fly debris on the surface of the sliding shaft from clogging the slider and affecting the efficiency of the filling cylinder.

[0017] 3. This invention reduces the resistance when the slider moves by having the rollers move synchronously with it. The rollers are embedded in the guide rail and roll, thus preventing the slider from getting stuck. This makes the cylinder movement smoother and improves the stability of the slider's movement along the slide shaft. Attached Figure Description

[0020] The technical solution of the present invention will now be clearly and completely described 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.

[0021] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides a novel sliver filling mechanism and its control method for a drawing frame, including a T-stand 1. A motor 2 is fixedly connected inside the T-stand 1. A transmission assembly 3 is provided at the output end of the motor 2. A clamping plate 4 is fixedly connected to the outside of the transmission assembly 3. A slider 5 is fixedly connected to the outside of the clamping plate 4. A pusher rod 6 is fixedly connected to the other side of the slider 5.

[0022] Specifically, T-stage 1 serves as the installation and support structure for the entire replenishment mechanism, motor 2 provides driving force for the replenishment action, transmission component 3 transmits the power of motor 2, and clamp 4 connects transmission component 3 and slider 5, enabling the power of transmission component 3 to be transmitted to slider 5. Slider 5 drives push rod 6 to move linearly, and push rod 6 directly contacts the cotton sliver to be replenished. Through its own movement, it pushes the cotton sliver to the designated position in the main unit, completing the replenishment conveying action.

[0023] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4The transmission assembly 3 includes a driven wheel 31, the inside of which is located at the output end of the motor 2. A belt 32 is fitted around the driven wheel 31, and an adjusting screw 33 is installed on the outside of the driven wheel 31. A fixed seat 34 is fixedly connected to the outside of the T-stage 1. A positioning seat 7 is fixedly connected to the outside of the T-stage 1. A sliding shaft 8 is installed inside the positioning seat 7. A nylon sleeve 10 is installed inside the slider 5. The inside of the slider 5 is slidably connected to the outside of the sliding shaft 8, and one side of the nylon sleeve 10 is attached to the outside of the sliding shaft 8. A limiting block 9 for blocking the slider 5 is fixedly connected to the outside of the T-stage 1.

[0024] Specifically, the driven wheel 31 drives the belt 32 to rotate. The belt 32, as a flexible transmission component, realizes the power transmission between the driven wheel 31 and other transmission components. The adjusting screw 33 adjusts the installation position of the driven wheel 31 by turning it, thereby adjusting the tension of the belt 32. The fixed seat 34 is used to fix and position the relevant components of the transmission assembly 3. The positioning seat 7 provides installation positioning for the sliding shaft 8. The sliding shaft 8 provides sliding guidance for the slider 5 and limits the movement trajectory of the slider 5. The nylon sleeve 10 reduces the sliding friction between the slider 5 and the sliding shaft 8, ensuring smooth movement of the slider 5. The limit block 9 is used to limit the maximum movement stroke of the slider 5, preventing the slider 5 from dislodging from the sliding shaft 8 or colliding with other components due to excessive movement. This can avoid frequent shutdowns for maintenance of the replenishing mechanism, improve the convenience of replenishing, and thus improve the production efficiency of the drawing frame.

[0025] Please see the appendix Figure 5 and attached Figure 6 The slider 5 has slots 11 on both sides of its exterior. Cleaning plates 12 are attached to both sides of the nylon sleeve 10. A cleaning sleeve 13 is installed inside the cleaning plate 12. An insert plate 14 is fixedly connected to one side of the cleaning plate 12. A fixing hole 15 is provided inside the insert plate 14. A housing 16 is fixedly connected to the outside of the slider 5. A pushing assembly 17 is provided inside the housing 16. The outside of the insert plate 14 is snapped into the inside of the slot 11. The pushing assembly 17 includes a spring 171, one end of which is fixedly connected to… The spring 171 is connected to the inside of the outer shell 16. A fixing post 172 passes through the inside of the spring 171. A push plate 173 is fixedly connected to the outside of the fixing post 172. The outside of the push plate 173 is slidably connected to the inside of the spring 171. The outside of the fixing post 172 is slidably connected to the inside of the spring 171. One side of the push plate 173 is fixedly connected to the other end of the spring 171. One end of the fixing post 172 is snapped into the inside of the fixing hole 15. The cleaning sleeve 13 is one of polyester fiber felt, nylon felt, soft polyurethane sleeve, and nylon fiber.

[0026] Specifically, slot 11 provides a snap-fit ​​mounting position for insert plate 14, enabling detachable connection between cleaning plate 12 and slider 5. Cleaning plate 12 is made of plastic material and is snapped onto the outside of slide shaft 8 using external force. Cleaning sleeve 13 contacts the surface of slide shaft 8 during slider 5 movement, removing dust and fly debris from the surface of slide shaft 8. Insert plate 14 is positioned by cooperating with slot 11. Fixing hole 15 fixes insert plate 14 to push assembly 17. Spring 171 provides elastic driving force for push plate 173. Fixing post 172 transmits the elastic force of push plate 173 to insert plate 14, fixing cleaning plate 12. Push plate 173 increases the force-bearing area of ​​spring 171, allowing the elastic force to be evenly transmitted to fixing post 172, thereby achieving rapid cleaning of slide shaft 8 surface and preventing dust and fly debris on slide shaft 8 surface from clogging slider 5 and affecting the efficiency of cylinder replenishment.

[0027] Please see the appendix Figure 7 and attached Figure 8 The outer shell 16 has a card plate 18 inside, and a roller 19 is fixedly connected to the upper surface of the card plate 18. Both ends of the T-stage 1 are fixedly connected to detection photoelectric sensors 21. The T-stage 1 has a guide rail 20 inside, and the roller 19 is slidably connected to the inside of the guide rail 20.

[0028] Specifically, the card plate 18 connects the roller 19 to the outer shell 16. The roller 19 cooperates with the guide rail 20 to change the single sliding friction between the slider 5 and the T-stage 1 into rolling plus sliding friction. The photoelectric sensor 21 is used to detect the position status of the slider 5 and provide real-time feedback on whether the slider 5 is in the initial standby position or has moved into place, providing a signal basis for the start and stop control of the motor 2. The guide rail 20 provides rolling guidance for the roller 19 and limits the movement path of the slider 5, thereby improving the smoothness of the slider 5's movement and also improving the cleaning stability of the cleaning plate 12.

[0029] A control method for a novel replenishing mechanism of a drawing frame includes the following steps: S1: Standby monitoring. The replenishment mechanism is in the initial standby state. The detection photoelectric sensors 21 at both ends of the T-stage 1 monitor the initial position of the slider 5 in real time. At the same time, the main unit detection module continuously monitors the full state of the cotton swabs in the main unit. When the cotton swabs in the main unit are full and pushed out, the main unit sends a replenishment start signal to the motor controller. S2: Replenishment cylinder drive. After receiving the replenishment cylinder start signal, the motor controller controls the motor 2 to rotate. The motor 2 drives the belt 32 to move synchronously through the transmission component 3. The belt 32 drives the slider 5 to slide along the slide shaft 8 towards the main unit through the clamping plate 4. The slider 5 drives the push cylinder rod 6 to move synchronously, pushing the cotton sliver to be replenished into the main unit. S3: Position detection. When the pusher rod 6 pushes the cotton sliver to be replenished to the preset position in the host, the host detection module detects that the cotton sliver is in position and sends a reset signal to the motor controller. At the same time, during the movement of the slider 5, the roller 19 on its outer plate 18 slides along the guide rail 20 to ensure smooth movement. S4: Mechanism reset. After receiving the reset signal, the motor controller controls the motor 2 to rotate in the opposite direction. Through the transmission component 3, the slider 5 and the push rod 6 move back to the initial position along the slide shaft 8. During the retraction process, the nylon sleeve 10 inside the slider 5 and the cleaning sleeve 13 on the cleaning plate 12 simultaneously rub and clean the surface of the slide shaft 8 to remove dust and fly shavings. S5: Stop and standby. When the detection photoelectric sensor 21 at the initial end of T-stage 1 detects that the slider 5 has returned to the initial position, it sends a stop signal to the motor controller. The motor controller controls the motor 2 to stop rotating, and the replenishing mechanism returns to the initial standby state, waiting for the next replenishing signal.

[0030] Work process: Before the cylinder replenishment mechanism is started, the slider 5 is in the initial position of the T-stage 1. The photoelectric sensor 21 detects that the slider 5 is in place, and the cylinder replenishment mechanism enters the standby state. When the cotton swab in the main unit is full and pushed out, the main unit detection module sends a replenishment start signal to the motor controller. The motor controller controls the motor 2 to rotate, the motor 2 drives the driven wheel 31 to rotate, the driven wheel 31 drives the belt 32 to move synchronously, the belt 32 drives the slider 5 to slide along the sliding shaft 8 towards the main unit through the clamp 4, and synchronously drives the push rod 6 to move. The push rod 6 pushes the cotton swab to be replenished into the main unit, thereby avoiding frequent shutdowns for maintenance of the replenishment mechanism and improving the convenience of replenishment. When the tampon tube reaches the preset position inside the main unit, the main unit detection module sends a reset signal to the motor controller. The motor controller controls the motor 2 to rotate in the reverse direction, which drives the slider 5 and the push rod 6 to retract to the initial position along the slide shaft 8 through the transmission component 3. During the retraction process, the nylon sleeve 10 inside the slider 5 and the cleaning sleeve 13 on the cleaning plate 12 move with the slider 5 and generate relative movement with the surface of the slide shaft 8. At the same time, when it is necessary to disassemble the cleaning plate 12, the fixing post 172 is pulled outward to a certain distance. The fixing post 172 drives the push plate 173 to compress the spring 171, so that one end of the fixing post 172 is disengaged from the fixing hole 15 of the insert plate 14. Then the insert plate 14 is pulled outward. The insert plate 14 drives the cleaning plate 12 and the cleaning sleeve 13 to separate from the slot 11 of the slider 5. Since the cleaning plate 12 is a plastic structure, it can be manually cleaned by being clamped to the slide shaft 8 by external force. This can achieve the effect of avoiding the dust and fly shavings on the surface of the slide shaft 8 from clogging the slider 5 and thus affecting the replenishment efficiency. At the same time, the roller 19 moves synchronously with the slider 5. The roller 19 is embedded in the guide rail 20 and rolls, which reduces the resistance when the slider 5 moves and avoids the slider 5 from getting stuck. This makes the cylinder movement smoother and improves the stability of the slider 5 moving along the slide shaft 8. When the cleaning plate 12 needs to be disassembled, pull the fixing post 172 outward to the maximum stroke to release the snap-fit ​​relationship between the outer shell 16 and the clamping plate 18, remove the clamping plate 18 from the inside of the outer shell 16, and the clamping plate 18 drives the roller 19 to disassemble simultaneously, completing the disassembly of the roller 19, so that the cleaning sleeve 13 can be replaced or the roller 19 can be repaired later.
