Description

Technical Field

[0001] The utility model relates to the technical field of air jet dust removal, in particular to an air jet dust removal mechanism of a double-sided knitting machine. Background Art

[0002] A double-sided knitting machine is a loom used to produce double-sided knitted fabrics. During the weaving process of knitted fabrics, a large amount of yarn hair will be generated, and the yarn hair attached to the surface of the knitted raw materials will also be scattered during the weaving process. In order to ensure the normal operation of the knitting machine and improve the production quality of the fabric, a dust removal mechanism is generally used to clean the fiber dust on its surface.

[0003] After searching, it was found that during the use of the Chinese patent "A jet dust removal control device for a large circular knitting machine" with authorization announcement number "CN210151333U", the electric push rod is controlled to extend and retract to drive the dust removal frame to open and close, thereby changing the horizontal distance between the air pump and the electric telescopic column, which is convenient for uniform air blowing and dust removal of the large circular knitting machine. When in use, the electric motor is turned on, and the fixed seat can be driven to rotate through the gear plate and the ring gear, thereby driving the air pump to rotate through the electric telescopic column and the dust removal frame, which is convenient for the air pump to perform all-round air blowing and dust removal on the large circular knitting machine without dead angles, further improving its dust removal efficiency.

[0004] Although the above application can remove dust from the knitting machine, the wind force blowing onto the knitting machine will change during the opening and closing process of the air pump. When the air pump gradually moves away from the knitting machine, the wind force blowing onto the knitting machine will weaken, resulting in a weakened cleaning effect, thereby affecting the dust removal effect on the knitting machine.

[0005] Therefore, an air jet dust removal mechanism for a double-sided knitting machine is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a jet dust removal mechanism for a double-sided knitting machine in order to solve the above-mentioned problem, thereby improving the problem that the wind force blown onto the knitting machine changes during the opening and closing process of the air pump. When the air pump gradually moves away from the knitting machine, the wind force blown onto the knitting machine will weaken, resulting in a weakened cleaning effect, thereby affecting the dust removal effect of the knitting machine.

[0007] The top of the rotary shaft is fixedly connected to the air outlet pipe, and the surface of the rotary shaft is slidably connected to the sliding frame. The bottom end of the rotary frame is fixedly connected to the rack, and the surface of the air outlet pipe is rotatably connected to the air outlet pipe, and the surface of the air outlet pipe is fixedly connected to the second gear, and the second gear is meshed with the rack.

[0008] Preferably, the dust removal device further comprises a rectangular frame fixedly connected to the other end of the air jet pipe, a baffle being rotatably connected to the inner wall of the rectangular frame, one end of the baffle rotating shaft extending through the rectangular frame and fixedly connected to a trigger plate, and a push rod fixedly connected to the lower end of the surface of the air outlet pipe, the other end of the push rod being remote from the bottom end of the trigger plate. As the angle between the air jet pipe and the horizontal plane gradually increases during reciprocating rotation, the baffle, the trigger plate, and the push rod facilitate gradually tilting the baffle. The baffle's tilt angle guides the blown air, facilitating the airflow to gradually gather and be blown out from below the baffle, thereby increasing the strength of the wind blowing onto the surface of the knitting machine and enhancing the dust removal effect.

[0009] Preferably, a coil spring is fixedly connected to the surface of the baffle shaft, and the other end of the coil spring is fixedly connected to the inner wall of the rectangular frame, which is conducive to driving the baffle to return to its initial state.

[0010] Preferably, a sealed bearing is embedded in the inner wall of the air outlet pipe, and the surface of the air jet pipe is fixedly connected to the inner edge of the sealed bearing. When the air jet pipe rotates, the stability of the connection between the air jet pipe and the air outlet pipe is ensured.

[0011] Preferably, a limit rod is fixedly connected to one side of the rectangular frame, and the surface of the limit rod is in contact with the bottom end of the trigger plate, which is conducive to limiting the reset rotation angle of the trigger plate and the baffle, and ensuring the stability of the device operation.

[0012] Preferably, the overall shape of the air jet pipe is "L"-shaped, so as to better blow the air to the surface of the knitting machine.

[0013] Preferably, the other end of the push rod is bent into a spherical shape, thereby reducing the friction between the push rod and the trigger plate when the push rod pushes the trigger plate.

[0014] The beneficial effects of the utility model are:

[0015] The above-mentioned dust removal device is set up, using the fan to introduce external air and spray it from the air nozzle to remove dust from the surface of the knitting machine, and driving the ring gear to drive the dust removal device to rotate synchronously at a uniform speed and maintain the same distance as the knitting machine to remove dust, which is conducive to maintaining stable wind force when the dust removal device is treating the knitting machine, thereby ensuring the dust removal effect on the knitting machine. While the air nozzle is reducing dust, it is conducive to driving the rack to move back and forth under the action of the rotating wheel, circular plate, round rod and sliding frame, so that the second gear drives the air nozzle to rotate back and forth about its own rotation center point while revolving to spray air and remove dust from the knitting machine, which is conducive to removing dust from the knitting machine from different angles, thereby improving the dust removal effect on the knitting machine;

[0016] When the angle between the air nozzle and the horizontal plane gradually increases during the reciprocating rotation, the baffle is gradually tilted under the action of the baffle, the trigger plate and the push rod. The inclination angle of the baffle is used to guide the blown wind, which is conducive to the wind gradually gathering and blowing out from the bottom of the baffle, thereby increasing the intensity of the wind blowing to the surface of the knitting machine and enhancing the dust removal effect.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] When implementing: Figure 1-6 As shown, a jet dust removal mechanism of a double-sided knitting machine includes: a mounting frame 1, a gear ring 2 is rotatably connected to the top of the mounting frame 1, a motor 3 is fixedly connected to the surface of the mounting frame 1, an output shaft of the motor 3 is fixedly connected to a first gear 4, the first gear 4 is meshed with the gear ring 2, and a dust removal device 5 is provided at the top of the gear ring 2; wherein, the dust removal device 5 includes three fans 51 fixedly connected to the top of the gear ring 2, the air outlet end of the fan 51 is connected to an air outlet pipe 52, the inner wall of the air outlet pipe 52 is rotatably connected to a runner 53, the top of the rotating shaft of the runner 53 passes through the air outlet pipe 52 and is fixedly connected to a circular plate 54, the top of the circular plate 54 is fixedly connected to a round rod 55, the surface of the round rod 55 is slidably connected to a sliding frame 56, the bottom end of the sliding frame 56 is fixedly connected to a rack 57, the surface of the air outlet pipe 52 is rotatably connected to a spray pipe 58, the surface of the spray pipe 58 is fixedly connected to a second gear 59, and the second gear 59 is meshed with the rack 57. The overall shape of the air blower 58 is L-shaped. The mounting frame 1 is mounted on the frame of the double-sided knitting machine. The entire device operates to remove dust without affecting the normal operation of the bidirectional knitting machine. The motor 3 is activated by the controller. The output shaft of the motor 3 drives the first gear 4 and rotates the ring gear 2, thereby driving the dust removal device 5 to rotate synchronously.

[0026] When the fan 51 is started by the controller, the fan 51 will guide the external wind into the outlet pipe 52 and blow it out from the nozzle pipe 58 to clean the fiber dust on the knitting machine. The air inlet end of the fan 51 is provided with a filter to filter the external wind. The runner 53 is set at an eccentric position of the outlet pipe 52. When the wind passes through the outlet pipe 52, it will drive the runner 53 to rotate. The round rod 55 is set at the eccentric position of the circular plate 54, and the surface of the round rod 55 is always in contact with the inner wall of the slide frame 56. Therefore, when the runner 53 drives the circular plate 54 to rotate, it will drive the slide frame 56 to reciprocate in the horizontal square through the round rod 55, and drive the rack 57 to move synchronously, so that the second gear 59 drives the nozzle pipe 58 to rotate back and forth while spraying air.

[0027] like Figure 3 、 Figure 4 and Figure 5As shown, the dust removal device 5 also includes a rectangular frame 510 fixedly connected to the other end of the air jet pipe 58. A baffle 511 is rotatably connected to the inner wall of the rectangular frame 510. One end of the baffle 511's rotating shaft extends through the rectangular frame 510 and is fixedly connected to a trigger plate 512. A push rod 514 is fixedly connected to the lower end of the surface of the air outlet pipe 52, with the other end of the push rod 514 away from the bottom end of the trigger plate 512. A coil spring 513 is fixedly connected to the surface of the baffle 511's rotating shaft, the other end of which is fixedly connected to the inner wall of the rectangular frame 510. The other end of the push rod 514 is curved into a spherical shape.

[0028] When the air jet pipe 58 sprays air to reduce dust, the wind will be sprayed out from the rectangular frame 510, and the baffle 511 is parallel to the horizontal plane in the initial state. During the downward rotation of the air jet pipe 58, when it rotates to a certain angle, the bottom end of the trigger plate 512 will contact the top end of the push rod 514, and the air jet pipe 58 continues to rotate along the same path. At this time, the push rod 514 will push the trigger plate 512 to drive the baffle 511 to tilt, and the coil spring 513 will contract. When the air jet pipe 58 can no longer rotate, one end of the baffle 511 will contact the inner top wall of the rectangular frame 510. At this time, the wind sprayed from the rectangular frame 510 will gather and spray from the bottom of the baffle 511, thereby increasing the intensity of the wind.

[0029] When the second gear 59 drives the air jet pipe 58 to rotate in the reverse direction and reset, the trigger plate 512 loses its resistance, and the coil spring 513 is released and drives the baffle 511 to reset.

[0030] like Figure 3 As shown, a sealed bearing 515 is embedded in the inner wall of the air outlet pipe 52, and the surface of the air jet pipe 58 is fixedly connected to the inner edge of the sealed bearing 515. The inner wall of the air outlet pipe 52 is fixedly connected to the outer edge of the sealed bearing 515. When the second gear 59 drives the air jet pipe 58 to rotate, the connection between the air jet pipe 58 and the air outlet pipe 52 is stable.

[0031] like Figure 5 As shown, a limit rod 516 is fixedly connected to one side of the rectangular frame 510, and the surface of the limit rod 516 is in contact with the bottom end of the trigger plate 512. When the coil spring 513 is released to drive the trigger plate 512 and the baffle 511 to reset and rotate, the limit rod 516 limits the reset rotation angle.

[0032] When the utility model is in use, the controller starts the motor 3 to drive the first gear 4 to rotate and the gear ring 2 to rotate, thereby driving the dust removal device 5 to rotate synchronously.

[0033] The controller starts the fan 51 to guide the outside air into the air outlet duct 52 and blow it out from the air nozzle 58 and the rectangular frame 510 to clean the fiber dust on the knitting machine. When the air passes through the air outlet duct 52, it drives the wheel 53 to rotate. The rotation of the wheel 53 drives the circular plate 54 to rotate, so that the round rod 55 drives the sliding frame 56 to move back and forth in the horizontal square, and drives the rack 57 to move back and forth synchronously, so that the second gear 59 drives the air nozzle 58 to rotate back and forth at its own rotation center point while revolving to spray air to spray air on the knitting machine. Dust removal. At the same time, when the air nozzle 58 rotates downward, when it rotates to a certain angle, the bottom end of the trigger plate 512 will contact the top end of the push rod 514, and the air nozzle 58 continues to rotate along the same path. At this time, the push rod 514 will push the trigger plate 512 to drive the baffle 511 to tilt, and the coil spring 513 will shrink. When the air nozzle 58 can no longer rotate, one end of the baffle 511 will contact the inner top wall of the rectangular frame 510. At this time, the wind ejected from the rectangular frame 510 will gather and eject from the bottom of the baffle 511, thereby increasing the strength of the wind.

[0034] It should be noted that the motor 3, fan 51, etc. in the above description are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the motor 3 and fan 51 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0035] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
