Description

Technical Field

[0001] This utility model belongs to the field of textile equipment technology, specifically a transmission device for a flax drawing machine. Background Technology

[0002] Currently, traditional flax sliver machines on the market share a single transmission mechanism between the feeding and drafting mechanisms. A motor is connected to both the feeding and drafting mechanisms via gears. To achieve the speed difference between the feeding and drafting mechanisms, gears with different numbers of teeth need to be replaced. This process is time-consuming and labor-intensive, reducing work efficiency.

[0003] Therefore, a transmission device for a flax slatting machine is proposed to address the above problems. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a transmission device for a flax sliver drawing machine, which has the advantage of adjusting the transmission ratio according to actual needs to adapt to different flax sliver feeding speeds and process requirements.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a transmission device for a flax sliver machine, comprising a frame, a feeding frame fixedly disposed above the frame, a feeding guide roller rotatably disposed inside the feeding frame, a feeding motor fixedly disposed on the front side of the frame, and an open transmission pin fixedly disposed on the rear side of the feeding motor.

[0006] Preferably, a second synchronous belt is attached to the end of the main shaft of the feeding motor, and a combing drive shaft is attached to the inside of the second synchronous belt.

[0007] By adopting the above technical solution, the feed motor is connected to the carding drive shaft via an open drive pin and a second synchronous belt. The open drive pin provides flexibility and stability in power transmission, facilitating maintenance and adjustment. The use of the second synchronous belt ensures the accuracy and efficiency of power transmission, precisely transmitting the power from the feed motor to the carding drive shaft, providing stable power support for subsequent carding processes.

[0008] Preferably, a feeding gear transmission assembly is fixedly provided on the front side of the frame, and a feeding roller transmission shaft is fixedly provided on the left side of the feeding gear transmission assembly.

[0009] By adopting the above technical solution, the setting of the feeding gear transmission group and the feeding roller drive shaft makes the power distribution during the feeding process more reasonable. The feeding gear transmission group can adjust the transmission ratio according to actual needs to adapt to different flax sliver feeding speeds and process requirements, while the feeding roller drive shaft further transmits power to the feeding roller to ensure that the flax sliver can be fed evenly and stably.

[0010] Preferably, a main motor is fixedly mounted on the front side of the frame, and a timing belt is attached to the end of the main shaft of the main motor, with a drafting roller drive shaft attached inside the timing belt.

[0011] By adopting the above technical solution, the main motor drives the drafting roller drive shaft to rotate via synchronous belt one. Synchronous belt one has the characteristics of high transmission efficiency and low noise, which can efficiently transmit the power of the main motor to the drafting roller drive shaft, reducing energy loss.

[0012] Preferably, the outer side of the drawing roller drive shaft is fitted with a take-off gear drive assembly, and the outer side of the take-off gear drive assembly is fitted with a strip-exit roller drive shaft.

[0013] By adopting the above technical solution, the coordination between the drafting gear drive assembly on the outside of the drafting roller drive shaft and the output roller drive shaft enables precise drafting of the flax sliver. The drafting gear drive assembly can adjust the transmission ratio according to process requirements, thereby controlling the rotational speed of the output roller drive shaft and achieving precise control of the flax sliver draft ratio, ensuring the fineness and uniformity of the flax sliver.

[0014] Preferably, a coil motor is fixedly mounted on the front side of the frame, a reducer is fixedly mounted on the end of the main shaft of the coil motor, a chain is attached to the front side of the reducer, and a coil chassis conveyor belt is attached to the inside of the chain.

[0015] By adopting the above technical solution, the coiling motor realizes the coiling operation of flax slivers through a reducer, chain, and coiling chassis conveyor belt. The reducer can reduce the speed of the coiling motor, increase the torque, and make the coiling process more stable. The chain drive has the characteristics of high transmission power and high reliability, which can ensure the stable operation of the coiling chassis conveyor belt and neatly coil the drafted flax slivers into the sliver can.

[0016] Preferably, a pressure bar cylinder is fixedly provided on the left side of the frame, and a pressure bar counterweight is fixedly provided below the pressure bar cylinder.

[0017] By employing the above technical solution, the combination of the pressing cylinder and the pressing counterweight can compact the flax strips wound in the sliver can. The pressing cylinder can adjust the pressure of the pressing counterweight as needed, making the flax strips more compact in the sliver can and reducing the problem of loosening during transportation and storage.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the combined design of the feeding frame and the feeding guide roller, enables flax slivers to smoothly enter the drawing machine. The rotatable feeding guide roller can actively guide the flax slivers, improving feeding efficiency and reducing the probability of problems such as jamming and tangling during the feeding process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The following describes an embodiment of this utility model based on its overall structure.

[0023] like Figures 1 to 4 As shown, this utility model provides a transmission device for a flax sliver drawing machine, including a frame 1. A feeding frame 20 is fixedly mounted on the top of the frame 1. A feeding guide roller 19 is rotatably mounted inside the feeding frame 20. A feeding motor 18 is fixedly mounted on the front side of the frame 1, and an open transmission pin 16 is fixedly mounted on the rear side of the feeding motor 18. The combined design of the feeding frame 20 and the feeding guide roller 19 allows the flax sliver to smoothly enter the drawing machine. The rotatable feeding guide roller 19 can actively guide the flax sliver, improving feeding efficiency and reducing the probability of problems such as jamming and tangling during feeding.

[0024] In this embodiment, a second synchronous belt 17 is attached to the end of the main shaft of the feed motor 18. A combing drive shaft 15 is attached inside the second synchronous belt 17. The feed motor 18 is connected to the combing drive shaft 15 via an open transmission pin 16 and the second synchronous belt 17. The open transmission pin 16 provides flexibility and stability in power transmission, facilitating maintenance and adjustment. The use of the second synchronous belt 17 ensures the accuracy and efficiency of power transmission, precisely transmitting the power of the feed motor 18 to the combing drive shaft 15, providing stable power support for subsequent combing processes. A feed gear transmission assembly 14 is fixed to the front of the frame 1, and a feed roller drive shaft 13 is fixed to the left side of the feed gear transmission assembly 14. The arrangement of the feed gear transmission assembly 14 and the feed roller drive shaft 13 makes the power distribution during the feeding process more reasonable. The feeding gear transmission group 14 can adjust the transmission ratio according to actual needs to adapt to different flax sliver feeding speeds and process requirements. The feeding roller transmission shaft 13 further transmits power to the feeding roller, ensuring that the flax sliver can be fed evenly and stably. The main motor 2 is fixedly installed on the front side of the frame 1. The end of the main shaft of the main motor 2 is attached to a timing belt 3. The drafting roller transmission shaft 12 is attached to the inside of the timing belt 3. The main motor 2 drives the drafting roller transmission shaft 12 to rotate through the timing belt 3. The timing belt 3 has the characteristics of high transmission efficiency and low noise, which can efficiently transmit the power of the main motor 2 to the drafting roller transmission shaft 12, reducing energy loss. The outer side of the drafting roller transmission shaft 12 is attached to an exit gear transmission group 11, and the outer side of the exit gear transmission group 11 is attached to an exit roller transmission shaft 8. The cooperation between the exit gear transmission group 11 and the exit roller transmission shaft 8 on the outer side of the drafting roller transmission shaft 12 can achieve precise drafting of the flax sliver. The drafting gear transmission group 11 can adjust the transmission ratio according to process requirements, thereby controlling the rotational speed of the drafting roller transmission shaft 8, achieving precise control of the draft ratio of the flax sliver, and ensuring the fineness and uniformity of the flax sliver. A coiling motor 7 is fixedly mounted on the front side of the frame 1. A reducer 6 is fixedly mounted at the end of the main shaft of the coiling motor 7. A chain 5 is attached to the front side of the reducer 6, and a coiling chassis conveyor belt 4 is attached to the inside of the chain 5. The coiling motor 7 performs the coiling operation of the flax sliver through the reducer 6, chain 5, and coiling chassis conveyor belt 4. The reducer 6 can reduce the rotational speed of the coiling motor 7, increase torque, and make the coiling process more stable. The chain drive 5 features high transmission power and high reliability, ensuring the stable operation of the conveyor belt 4 on the sliver winding chassis. It neatly winds the drafted flax sliver into the sliver can. A pressing cylinder 10 is fixedly installed on the left side of the frame 1, and a pressing weight 9 is fixedly installed below the pressing cylinder 10. The combination of the pressing cylinder 10 and the pressing weight 9 compacts the flax sliver wound in the sliver can. The pressing cylinder 10 can adjust the pressure of the pressing weight 9 as needed, making the flax sliver more compact in the sliver can and reducing the problem of loosening during transportation and storage.

[0025] Working principle and process of a transmission device for a flax slitting machine: When the feed motor 18 starts, its main shaft rotates, transmitting power through the open transmission belt 16. At the same time, the synchronous belt 17 attached to the end of the feed motor 18 main shaft starts to run, driving the combing drive shaft 15 attached inside to rotate. The rotation of the carding drive shaft 15 prepares for subsequent carding work, and the power of the feeding motor 18 causes the feeding guide roller 19 to rotate inside the feeding frame 20, feeding the flax sliver into the drawing frame. The feeding gear transmission group 14 starts working under the drive of the feeding motor 18, which transmits power to the feeding roller drive shaft 13 on the left side to further transport and pre-process the fed flax sliver. The main motor 2 starts, and its main shaft rotates, driving the synchronous belt 3 attached to the end of the main shaft to rotate. The drafting roller drive shaft 12 attached inside the synchronous belt 3 rotates accordingly. The exit gear transmission group 11 attached to the outside of the drafting roller drive shaft 12 starts working, transmitting power to the exit roller drive shaft 8 attached to the outside to draft the flax sliver, so that the flax sliver reaches the appropriate fineness and uniformity. The coiling motor 7 starts, and its main shaft rotates, transmitting power to the reducer 6 for deceleration. The chain 5 attached to the front of the reducer 6 starts to operate, driving the conveyor belt 4 of the coiling chassis attached inside to rotate, coiling the stretched flax sliver and placing it orderly in the sliver can. The pressing cylinder 10 on the left side of the frame 1 starts, driving the pressing weight 9 fixed below to press down, properly compacting the coiled flax sliver, ensuring the compactness and stability of the flax sliver in the sliver can.
