Abstract
Description
Technical Field
[0001] This utility model relates to the field of knitting machine technology, specifically to a dust removal device for a double-sided knitting machine. Background Technology
[0002] The needles of a double-sided knitting machine are mounted on a needle cylinder. During knitting, cotton fibers, lint, and other debris from the yarn may remain on the needles. To ensure knitting quality, these debris must be removed by blowing air. Then, the cotton fibers, lint, and dust are sucked out and cleaned by the machine's exhaust fan, thus achieving dust removal during the operation of the double-sided knitting machine.
[0003] Currently, the air blowing pipe for dust removal is generally set on the fixed ring. The fixed ring is driven to rotate by the drive mechanism, and the air blowing pipe on the fixed ring rotates around the needle cylinder to blow air onto the knitting needles to remove impurities.
[0004] The inventors of this application discovered that, due to the limitations imposed by the support columns of a double-sided knitting machine, the dust collector ring, carrying the air blowing pipe, needs to rotate back and forth within a certain angle, and cannot rotate in a circle. How to control the timely forward and reverse rotation of the dust collector ring to ensure that the air blowing pipe does not collide with the support columns of the machine is a problem that urgently needs to be solved by technicians in the industry. Utility Model Content

[0009] The transmission rack is arc-shaped and is disposed on the dust removal ring, and meshes with the transmission gear. The drive motor is used to drive the transmission rack to reciprocate.
[0010] The sensor is mounted on the fixed bracket;
[0011] Multiple air blowing pipes are evenly distributed on the dust removal ring at intervals and connected to an external high-pressure air source through connecting hoses.

[0044] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0045] As described in the background section of this application, the air blowing pipe for dust removal of knitting needles in double-sided knitting machines is generally set on a fixed ring. The fixed ring is driven to rotate by a drive mechanism, and the air blowing pipe on the fixed ring rotates around the needle cylinder to blow air onto the knitting needles to remove lint and other debris.
[0046] The inventors of this application discovered that, due to the limitations imposed by the support columns of a double-sided knitting machine, the dust collector ring, carrying the air blowing pipe, needs to rotate back and forth within a certain angle, and cannot rotate in a circle. How to control the timely forward and reverse rotation of the dust collector ring to ensure that the air blowing pipe does not collide with the support columns of the machine is a problem that urgently needs to be solved by technicians in the industry.
[0047] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows:
[0048] Figure 1 This is a schematic diagram of the dust removal device for a double-sided knitting machine in an embodiment of this utility model. Figure 2 As described in the embodiments of this utility model Figure 1 Enlarged view of point A in the image. Figure 3 As described in the embodiments of this utility model Figure 1 Enlarged view of point B in the image.
[0049] like Figures 1 to 3 As shown, the dust removal device for the double-sided knitting machine in this embodiment includes: a fixed bracket 1, a dust removal ring 2, a drive motor 3, a transmission rack 4, a sensor 5, an air blowing pipe 6, and a controller 7.
[0050] The fixed bracket 1 and the drive motor 3 are respectively fixedly mounted on the machine base of the double-sided knitting machine, and the output shaft of the drive motor 3 is equipped with a transmission gear 31.
[0051] The dust removal ring 2 is rotatably mounted on the fixed bracket 1.
[0052] The transmission rack 4 is arc-shaped as a whole, and the arc of the transmission rack 4 is the same as that of the dust removal ring 2.
[0053] The transmission rack 4 is mounted on the top surface of the dust collector ring 2. The teeth of the transmission rack 4 protrude from the inner circumference of the dust collector ring 2 and mesh with the transmission gear 31. The drive motor 3 drives the transmission gear 31 to rotate in both directions. When the transmission gear 31 rotates, it drives the transmission rack 4 and the dust collector ring 2 to rotate back and forth around the central axis.
[0054] Sensor 5 is mounted on fixed bracket 1.
[0055] Multiple air blowing pipes 6 are provided, evenly distributed at intervals on the dust removal ring 2. They are connected to an external high-pressure air source via connecting hoses 61. A solenoid valve 62 is installed on the connecting hose 61 to control the opening and closing of the air blowing pipes 6. When the transmission rack 4 rotates, it drives the dust removal ring 2 and the air blowing pipes 6 to rotate. When the transmission gear 31 moves from one end of the transmission gear 4 to the other end, the multiple air blowing pipes 6 rotate 360° together. That is, the multiple air blowing pipes 6 move around the needle plate of the double-sided knitting machine once, blowing air to clean all the knitting needles on the needle plate to remove cotton lint and other debris from the needles, achieving 360° dust removal without dead angles.
[0056] The drive motor 3, sensor 5 and solenoid valve 62 are electrically connected to the controller 7, and the controller 7 controls each component to perform corresponding preset actions according to the preset program.
[0057] In this embodiment, the controller controls the drive motor to rotate the dust removal ring and the air blowing pipe around the central axis via the transmission rack. When the sensor detects that the transmission rack has reached the preset position, it sends a signal to the controller. After receiving the signal from the sensor, the controller controls the drive motor to reverse. The drive motor drives the dust removal ring and the air blowing pipe to run back and forth in reverse to avoid the support column of the machine. When the transmission gear moves from one end of the transmission rack to the other end, the multiple air blowing pipes rotate a total of 360°, realizing the blowing and dust removal of all the knitting needles on the needle plate.
[0058] As can be seen from the above, the dust removal device for the double-sided knitting machine in this embodiment consists of a fixed bracket, a dust removal ring, a drive motor, a transmission rack, a sensor, air blowing pipes, and a controller. The fixed bracket and the drive motor are mounted on the machine base of the double-sided knitting machine. The output shaft of the drive motor is equipped with a transmission gear. The dust removal ring is mounted on the fixed bracket. The arc-shaped transmission rack is mounted on the dust removal ring and meshes with the transmission gear. The sensor is mounted on the fixed bracket. Multiple air blowing pipes are evenly distributed on the dust removal ring and connected to an external high-pressure air source through a connecting hose. A solenoid valve is mounted on the connecting hose. The dust removal device for the double-sided knitting machine in this embodiment is controlled by a controller. The drive motor drives the dust removal ring and the air blowing pipe to rotate around the central axis. When the sensor detects that the transmission rack has reached the preset position, it sends a signal to the controller. After receiving the signal from the sensor, the controller controls the drive motor to reverse. The drive motor drives the dust removal ring and the air blowing pipe to run in reverse to avoid the support column of the machine. When the transmission gear moves from one end of the transmission rack to the other end, multiple air blowing pipes rotate a total of 360°, realizing the blowing and dust removal of all needles on the needle plate. The controller can set parameters such as the running speed of the drive motor and the opening and closing of the solenoid valve to adapt to the knitting speed of the double-sided knitting machine.
[0059] Optionally, in this embodiment, the dust removal device for the double-sided knitting machine has protrusions 41 at both ends of the transmission rack 4.
[0060] Two sensors 5 are provided, each mounted on the fixed bracket 1. When sensor 5 detects the protrusion 41 at the end of the transmission rack 4, it sends a signal to the controller 7. The controller controls the drive motor 3 to reverse, and the drive motor 3 drives the dust removal ring 2 and the air blowing pipe 6 to rotate in the opposite direction. This ensures that the air blowing pipe 6 does not collide with the support column on the double-sided knitting machine table, and also ensures that the drive motor 3 does not slip at the end of the transmission rack 4, thus preventing the drive motor 3 from being overloaded and damaged due to increased load.
[0061] Furthermore, in this embodiment, the dust removal device for the double-sided knitting machine has a central angle of 120° for the arc-shaped transmission rack 4.
[0062] There are three fixed brackets 1 and three air blowing pipes 6.
[0063] Three fixed supports 1 are evenly arranged at 120° intervals along the circumference of the dust removal ring 2, and three air blowing pipes 6 are also arranged at 120° intervals along the circumference of the dust removal ring 2. The fixed supports 1 and air blowing pipes 6 are staggered, so that adjacent fixed supports 1 and air blowing pipes 6 are arranged at 60° intervals.
[0064] Two sensors 5 are respectively mounted on two fixed brackets 1. The drive motor 3 is mounted next to another fixed bracket 1. The transmission gear 31 and the two sensors 5 are also evenly arranged at 120° intervals along the circumference of the dust removal ring 2.
[0065] In this embodiment, the central angle of the transmission rack is 120°, and the drive motor drives the transmission rack and the dust removal ring to switch back and forth by 120°. When the dust removal ring rotates 120°, the three air blowing pipes rotate 120° respectively, for a total rotation of 360°, so as to achieve 360° dust removal without dead angles on the needles of the double-sided knitting machine.
[0066] Optionally, in this embodiment, the dust removal device for a double-sided knitting machine has a limiting groove on the top surface of the dust removal ring 2.
[0067] The transmission rack 4 is embedded in the limiting groove of the dust removal ring 2 and fixed to the dust removal ring 2 by bolts, so that the transmission gear 4 is positioned and kept stable on the dust removal ring 2.
[0068] Furthermore, in this embodiment, the dust removal device for the double-sided knitting machine includes a fixed bracket 1 comprising a base 11, a support frame 12, and a top plate 13.
[0069] The base 11 is fixed on the machine table of the double-sided knitting machine.
[0070] The top surface of the base 11 is provided with a limiting step 111. The dust removal ring 2 is rotatably mounted on the base 11. The arc-shaped inner wall of the dust removal ring 2 abuts against the limiting step 111 of the base 11, so that the dust removal ring 2 is positioned on the base 11 of the three fixed supports 1.
[0071] The support frame 12 is vertically mounted on the base 11, and the top plate 13 is mounted on the top of the support frame 12. The sensor 5 is mounted on the top plate 13 of the fixed bracket 1 to facilitate the fixing of the sensor 5.
[0072] Furthermore, in this embodiment, the dust removal device for the double-sided knitting machine, the fixed bracket 1, also includes a roller 14.
[0073] The roller 14 is rotatably mounted on the support frame 12 and is horizontally positioned, abutting against the top surface of the dust removal ring 2, making the dust removal ring 2 more stable when rotating and preventing it from jumping.
[0074] Optionally, in this embodiment of the dust removal device for double-sided knitting machines, the end of the air blowing pipe 6 is provided with a fixing clip 63, and the air blowing pipe 6 is clamped and fixed to the dust removal ring 2 by the fixing clip 63.
[0075] Optionally, in this embodiment, the dust removal device for the double-sided knitting machine has an air pressure regulating valve needle on the solenoid valve 62. The air pressure of the air blowing pipe 6 can be adjusted by the air pressure regulating valve needle to adapt to the air blowing requirements of different yarns.
[0076] Optionally, in this embodiment, the dust removal device for the double-sided knitting machine has a dust removal ring 2 formed by splicing together multiple arc-shaped segments 21.
[0077] Both ends of the arc segment 21 are provided with assembly slots. During splicing, two adjacent arc segments 21 are engaged and limited by the assembly slots and then connected and fixed by fixing bolts to complete the connection and assembly of the dust removal ring 2.
[0078] The dust removal ring 2 can be disassembled into multiple arc-shaped segments 21, which facilitates the transportation and storage of the dust removal ring 2.
