Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile machinery technology, specifically to a blowing and suction duct for textile machinery. Background Technology
[0002] Textile machinery is short for textile equipment, referring to the mechanical equipment used in the entire textile production process, including fiber processing, spinning, weaving, and dyeing. Textile production involves precision operations such as fiber drafting, twisting, and gathering, which can easily generate problems such as fly yarn, yarn breakage, and fiber accumulation. If these problems are not addressed in a timely manner, they will directly affect yarn quality, equipment efficiency, and the workshop environment.
[0003] To avoid impacting production, existing textile machines are generally equipped with a blower-suction structure, which mainly uses negative pressure suction to remove fiber debris, fly ash, and dust, thereby improving the workshop environment.
[0004] During the spinning process, the yarn may break for some reason. The existing method is to set up an automatic splicing machine on one side of the spinning machine to automatically detect and repair the broken yarn, replacing the traditional manual splicing operation.
[0005] Automatic splicing machines typically need to be moved periodically to inspect the yarn on the spinning machine, which presents the following problems:
[0006] 1. The blow-suction duct is close to the textile machine: During the movement of the automatic splicing machine, there is a high probability of collision between the automatic splicing machine and the blow-suction duct, which increases the probability of damage to the blow-suction duct and the automatic splicing machine.
[0007] 2. The blower and suction duct is far away from the textile machine (located behind the automatic splicing machine): The distance between the blower and suction duct and the textile machine is large, resulting in poor blower and suction effect and high power of the external negative pressure machine. Utility Model Content
[0008] To address the shortcomings of existing technologies, this utility model provides a blowing and suction duct for textile machinery, which can automatically avoid automatic splicing machines.
[0009] To achieve the above objectives, this utility model provides the following technical solution: a blowing and suction duct for a textile machine, comprising a first straight pipe fixedly connected to the output end of a movable negative pressure machine above the main body of the textile machine, an upper mounting cylinder fixedly connected to the lower end of the first straight pipe, a power mechanism, a positioning mechanism and two monitoring mechanisms connected to the side wall of the upper mounting cylinder, a rotating assembly connected to the output end of the power mechanism, the upper end of the rotating assembly connected to the lower end of the upper mounting cylinder, a lower mounting cylinder connected to the lower end of the rotating assembly, a Z-shaped pipe fixedly connected to the lower end of the lower mounting cylinder, a second straight pipe fixedly connected to the lower end of the Z-shaped pipe, a plurality of blowing and suction heads fixedly connected to one side of the second straight pipe, the plurality of blowing and suction heads facing the main body of the textile machine, and two monitoring mechanisms arranged symmetrically along the axis of the upper mounting cylinder, and both monitoring mechanisms being parallel to the main body of the textile machine.
[0010] Furthermore, the power mechanism includes a motor and a first gear. The outer wall of the motor is fixedly connected to the side wall of the upper end of the upper mounting cylinder, the output shaft of the motor is fixedly connected to the first gear, and the first gear is connected to the rotating assembly.
[0011] Furthermore, the rotating assembly includes a connecting seat and a second gear. The lower end of the connecting seat is fixedly connected to the upper end of the lower mounting cylinder, and the upper end of the connecting seat is fixedly connected to the bottom surface of the second gear. The second gear is rotatably connected to the lower end of the upper mounting cylinder through a bearing. The second gear is connected to one end of the positioning mechanism, and the first gear meshes with the second gear.
[0012] Furthermore, the positioning mechanism includes a trigger plate, two support plates, and two contact sensors. The lower end of the trigger plate is fixedly connected to the upper surface of the second gear. One end of each of the two support plates is fixedly connected to the side wall of the lower end of the upper mounting cylinder. The two support plates are arranged at 90° on the surface of the upper mounting cylinder. The other end of each of the two support plates is fixedly connected to one end of each of the two contact sensors. The upper end of the trigger plate is aligned with the lower end of each of the two contact sensors.
[0013] Furthermore, the monitoring mechanism includes a distance monitoring radar and a mounting bracket. One end of the mounting bracket is fixedly connected to the side wall of the upper end of the upper mounting cylinder, and the other end of the mounting bracket is fixedly connected to the outer wall of the distance monitoring radar.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This type of blowing and suction duct for textile machinery uses a distance monitoring radar to monitor the movement of the automatic splicing machine in real time. When the automatic splicing machine approaches, the monitoring mechanism triggers the power mechanism to start, driving the rotating component to rotate the blowing and suction head to a position away from the main body of the textile machinery, providing moving space for the automatic splicing machine, significantly reducing the probability of collision between the blowing and suction duct and the automatic splicing machine, and reducing the risk of equipment damage.
[0016] 2. This type of blowing and suction duct for textile machines, during normal operation, has the blowing and suction head close to the main body of the textile machine to ensure efficient removal of fly and debris; when avoiding collisions, the blowing and suction head rotates to a position away from the machine, without affecting the operation of the automatic splicing machine. This solves the contradiction of "easy collision when close" or "poor effect when far away" caused by the fixed position of traditional ducts. At the same time, it can reduce the power requirement of the mobile negative pressure machine and save energy.
[0017] 3. The blowing and suction duct of this type of textile machine has a positioning mechanism that uses a trigger plate and a contact sensor to precisely control the rotation angle of the blowing and suction head. This ensures that space is fully cleared when avoiding obstacles and that the head accurately returns to its working position when resetting. This avoids functional failures caused by excessive or insufficient rotation and improves the stability of equipment operation. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Please see Figures 1-4 A blowing and suction duct for a textile machine includes a first straight pipe 2 fixedly connected to the output end of a movable negative pressure machine 16 above the main body 1 of the textile machine. The lower end of the first straight pipe 2 is fixedly connected to an upper mounting cylinder 10. The side wall of the upper mounting cylinder 10 is connected to a power mechanism, a positioning mechanism, and two monitoring mechanisms. The output end of the power mechanism is connected to a rotating assembly. The upper end of the rotating assembly is connected to the lower end of the upper mounting cylinder 10. The lower end of the rotating assembly is connected to a lower mounting cylinder 3. The lower end of the lower mounting cylinder 3 is fixedly connected to a Z-shaped pipe 15. The lower end of the Z-shaped pipe 15 is fixedly connected to a second straight pipe 4. A plurality of blowing and suction heads are fixedly connected to one side of the second straight pipe 4. The plurality of blowing and suction heads face the main body 1 of the textile machine. The two monitoring mechanisms are symmetrically arranged along the axis of the upper mounting cylinder 10, and both monitoring mechanisms are parallel to the main body 1 of the textile machine.
[0025] like Figures 1 to 4As shown, when the automatic splicing machine moves left and right along the front side of the main body 1 of the textile machine, when the automatic splicing machine moves into the monitoring range of the monitoring mechanism on the corresponding side, the monitoring mechanism detects the approach of the object and immediately sends an electrical signal to the control cabinet. Under the control of the controller inside the control cabinet, the power mechanism is automatically started. After the power mechanism is started, the output end of the power mechanism will rotate with the rotating component. After the rotating component rotates, it will rotate with the lower mounting cylinder 3, Z-shaped pipe 15, No. 2 straight pipe 4 and several blow-suction heads. This will allow several blow-suction heads that were originally close to the side of the main body 1 of the textile machine to rotate to a position away from the main body 1 of the textile machine. At this time, space is provided for the movement of the automatic splicing machine. When the automatic splicing machine returns to its original position, several blow-suction heads will automatically return to their original position through the power mechanism (this can be set in advance by the controller. For example, if the automatic splicing machine takes 30 seconds to go back and forth once, it can be set in advance so that when the monitoring mechanism detects that the automatic splicing machine is approaching and has moved several blow-suction heads to a different position, it can automatically return after 30 seconds).
[0026] It is important to note here that:
[0027] The opening and closing of the aforementioned monitoring and power mechanisms are controlled by a PLC controller. Alternatively, the controller built into the main body 1 of the textile machine can also be used; no specific limitation is imposed.
[0028] The main body of the textile machine 1, the mobile negative pressure machine 16, and the unmarked automatic splicing machine located on the front side of the main body of the textile machine 1 are all existing mature technologies.
[0029] The main body 1 of the textile machine includes, but is not limited to: an opening mechanism for loosening raw materials (such as raw cotton and chemical fibers) into fiber bundles and removing large impurities; a combing mechanism for further combing fibers to form a parallel fiber web; a drafting mechanism for stretching fiber bundles to the required fineness and improving uniformity; a twisting mechanism for imparting twist to the yarn and enhancing its strength; a winding mechanism for winding the yarn into a bobbin for easy subsequent processing; and a forming mechanism for controlling the winding shape of the yarn bobbin (such as conical or pagoda-shaped).
[0030] The automatic splicing machine includes, but is not limited to: a robotic arm assembly that performs actions such as yarn grabbing, threading, and winding; a yarn finding head assembly that quickly locates the breakage position and improves the reliability of the splice; a yarn processing mechanism that cleans, adjusts tension, and recycles waste yarn; a breakage detection module that detects breakage signals through current / vibration sensors; and a central controller that coordinates the robotic arm's movements, sensor data, and power output.
[0031] The mobile negative pressure unit 16 includes, but is not limited to: an electric motor that provides rotational power to the impeller and drives the negative pressure system; a multi-bladed centrifugal impeller made of high-strength alloy steel or aluminum alloy; a fully enclosed metal casing with internal guide plates to optimize airflow path; inlet and outlet pipes with a flared design to expand the air collection area and a silencer to reduce noise at the outlet; an electric mobile trolley that moves on a track above the main body of the textile machine 1; and a controller that automatically adjusts the fan speed and controls the direction and speed of the trolley.
[0032] As a preferred embodiment of this utility model, the power mechanism includes a motor 6 and a first gear 7. The outer wall of the motor 6 is fixedly connected to the side wall of the upper end of the upper mounting cylinder 10. The output shaft of the motor 6 is fixedly connected to the first gear 7. The first gear 7 is connected to the rotating assembly.
[0033] More specifically, when the automatic connector machine approaches, the monitoring mechanism detects the approaching object, and the controller starts the motor 6. The output shaft of the motor 6 drives the first gear 7 to rotate, and the first gear 7 drives the rotating component to rotate.
[0034] As a preferred embodiment of this utility model, the rotating assembly includes a connecting seat 5 and a second gear 8. The lower end of the connecting seat 5 is fixedly connected to the upper end of the lower mounting cylinder 3, and the upper end of the connecting seat 5 is fixedly connected to the bottom surface of the second gear 8. The second gear 8 is rotatably connected to the lower end of the upper mounting cylinder 10 through a bearing. The second gear 8 is connected to one end of the positioning mechanism, and the first gear 7 meshes with the second gear 8.
[0035] More specifically, after the first gear 7 rotates, it will cause the second gear 8 to rotate as well. The rotation of the second gear 8 will cause the connecting seat 5 fixed to it to rotate as well. After the connecting seat 5 rotates, it will cause the lower mounting cylinder 3 connected to its lower end to rotate, thereby causing the Z-shaped tube 15 and the second straight tube 4 to rotate together.
[0036] As a preferred embodiment of this utility model, the positioning mechanism includes a trigger plate 14, two support plates 12, and two contact sensors 13. The lower end of the trigger plate 14 is fixedly connected to the upper surface of the second gear 8. One end of each of the two support plates 12 is fixedly connected to the side wall of the lower end of the upper mounting cylinder 10. The two support plates 12 are arranged at 90° on the surface of the upper mounting cylinder 10. The other end of each of the two support plates 12 is fixedly connected to one end of each of the two contact sensors 13. The upper end of the trigger plate 14 is aligned with the lower end of the two contact sensors 13.
[0037] More specifically, when motor 6 starts, gear 8 begins to rotate. At this time, trigger plate 14 rotates along with gear 8 and separates from the contact sensor 13 that was originally in contact. After gear 8 rotates 90°, trigger plate 14 comes into contact with another contact sensor 13, and motor 6 stops automatically. This allows Z-shaped tube 15 and straight tube 4 to rotate 90° and then stop automatically.
[0038] When the automatic splicing machine returns to its original position, the motor 6 starts and reverses, and then the trigger plate 14 returns again through the second gear 8. When the trigger plate 14 contacts the first contact sensor 13 again, it stops again, so that it can continue to blow and suck air towards the main body of the textile machine 1.
[0039] As a preferred embodiment of this utility model, the monitoring mechanism includes a distance monitoring radar 9 and a mounting bracket 11. One end of the mounting bracket 11 is fixedly connected to the side wall of the upper end of the upper mounting cylinder 10, and the other end of the mounting bracket 11 is fixedly connected to the outer wall of the distance monitoring radar 9.
[0040] More specifically, when the automatic connector approaches, the distance monitoring radar 9 detects the approaching object and then quickly transmits an electrical signal to the controller. The controller can then quickly start the motor 6, thereby controlling the rotation of the Z-shaped tube 15 and the second straight tube 4.
[0041] Finally, it should be noted that in other embodiments, a protective shell can be fitted over the first gear 7 and the second gear 8 to prevent cotton lint from falling into the meshing area and causing blockage, which would affect the normal rotation of the first gear 7 and the second gear 8. Furthermore, a displacement sensor can be installed on the first gear 7 or the second gear 8 to monitor the rotation of the first gear 7 and the second gear 8 in real time after the motor 6 starts, and to issue an alarm in time when there is an abnormality (such as jamming), and to stop the movement of the automatic coupling machine through the controller to avoid collision. At the same time, an audible and visual alarm can also be installed so that the staff can be alerted in time when an abnormality occurs.
[0042] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
