Description

Technical Field

[0001] The utility model relates to the technical field of knitting equipment, in particular to a knitting machine pressing device. Background Art

[0002] The knitting machine is suitable for the following raw materials: nylon multifilament (thread), polypropylene filament (thread), polypropylene, polyester, nylon, PP, low elasticity, high elasticity, cotton yarn (thread), pearl yarn, leather, mixed, etc. The high-speed walking knitting machine has a complete set of N-color automatic conversion devices, and the motor driven by the computer control operation automatically switches between the yarn feeders, making the knitting of multi-color patterns simple and easy.

[0003] During the operation of the braiding machine, in order to ensure that the wire rope will not fall off when it breaks, it is usually necessary to use a clamping device to tighten the wire rope. The Chinese utility model patent "A braiding machine clamping device" with the publication number (CN208562726U) discloses: including a support frame, a pressure spring, a fixing frame, a hub frame, a hub shaft, a connecting plate, a clamping hub, a guide wheel and a gear plate; the clamping device is installed on the outside of the guide wheel so that the clamping hub is in close contact with the guide wheel. When the braiding machine fails or the wire rope breaks, the close contact between the clamping hub and the guide wheel will prevent the wire rope from falling off, avoiding the situation of having no strength to reel in the wire rope. Moreover, when the braiding machine drives the guide wheel to rotate, the connected clamping hub will rotate relatively with the cooperation of the hub shaft due to the friction force, so that the wire rope clamping work can be performed without affecting the normal use of the braiding machine.

[0004] However, the above device still has some defects, such as relying only on the clamping hub to contact the guide wheel and the wire rope at the same time. If the wire rope is too thick or too thin, it is easy to affect the contact state between the clamping hub and the guide wheel, resulting in the guide wheel being unable to effectively drive the rotation of the clamping roller, thereby having a negative impact on the transmission of the guide wheel and the wire rope.

DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0021] The following describes the braiding machine pressing device according to the embodiment of the utility model in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 3 As shown, the pressing device of the braiding machine according to the embodiment of the utility model may include a guide roller 30 and a pressing mechanism 50.

[0023] The braiding machine body 10 is arranged on the top surface of the braiding machine body 10 through the support rod 20 , and the guide roller 30 is provided with a guide groove 31 .

[0024] It should be noted that the braiding machine body 10 described in this embodiment has a complete N-color automatic conversion device. The braiding machine body 10 can drive the guide roller 30 to rotate and transmit the wire rope on the guide roller 30. Since it is a prior art, it will not be described in detail here.

[0025] The pressing mechanism 50 is movably disposed on the braiding machine body 10 via the first driving component 40 .

[0026] It should be noted that the first driving component 40 described in this embodiment may be a cylinder, a telescopic motor, etc. The first driving component 40 can drive the clamping mechanism 50 to move and adjust the distance between it and the guide roller 30.

[0027] The clamping mechanism 50 may include a connecting frame 51, a first clamping roller 52 and a second clamping roller 53, wherein one side of the connecting frame 51 is connected to the first driving component 40, and the other side of the connecting frame 51 is provided with a through hole 511, and the through hole 511 is horizontally arranged.

[0028] The first pressing roller 52 is arranged in an I-shape, a through hole 511 is arranged in the middle of the first pressing roller 52 , the first pressing roller 52 abuts against the guide roller 30 , and an adjusting member 60 for controlling the rotation of the pressing roller is arranged on the connecting frame 51 .

[0029] The second pressing roller 53 is arranged inside the first pressing roller 52, and a frame 532 is movably provided on the second pressing roller 53, and the frame 532 is connected to the connecting frame 51 through a spring 533. An arcuate annular groove 531 is arranged outside the second pressing roller 53.

[0030] It is understandable that the arc-shaped annular groove 531 can better fit the wire rope in the guide groove 31 .

[0031] It can be understood that the spring 533 can make the contact between the second pressing roller 53 and the wire rope closer, ensuring that the wire rope will not fall between the two.

[0032] The first clamping roller 52 is symmetrically provided with a rotating ring 523 on its outer edge, and the frame 532 is slidably provided between the rotating rings 523 on both sides, which helps to improve the rotation stability of the first clamping roller 52 and the second clamping roller 53 and facilitates the limitation of the wire rope.

[0033] Specifically, in the actual process of clamping the guide roller 30 and the wire rope, the relevant personnel first drive the clamping mechanism 50 to move through the first driving component 40, so that the first clamping roller 52 is in close contact with the guide roller 30, and at the same time, the second clamping roller 53 can be in close contact with the wire rope in the guide groove 31, and the second clamping roller 53 can adjust its position according to wire ropes of different thicknesses under the action of the spring 533.

[0034] When the knitting machine body 10 fails to work or the wire rope breaks, the close contact between the second clamping roller 53 and the wire rope will prevent the wire rope from falling, thus avoiding the situation where there is no strength to reel in the wire rope. Moreover, when the knitting machine body 10 drives the guide roller 30 to rotate, the first clamping roller 52 will rotate due to the friction force, and the second clamping roller 53 can rotate relative to the frame 532 as the wire rope is transmitted. This ensures that the wire rope compression work can be performed without affecting the normal use of the knitting machine body 10.

[0035] In an embodiment of the present invention, the adjusting member 60 may include an electromagnetic clutch and a motor, and the electromagnetic clutch is connected to the motor and the central axis of the first pressing roller 52 respectively.

[0036] It should be noted that the electromagnetic clutch described in this embodiment can store energy in the motor when the guide roller 30 drives the first clamping roller 52 to rotate, and can be connected to the motor so that the motor controls the first clamping roller 52 to rotate forward and reverse.

[0037] When the guide roller 30 drives the first pressing roller 52 to rotate, the mechanical energy of the input end is transmitted to the electromagnetic clutch. In this process, the input end and the output end of the electromagnetic clutch remain separated, that is, the motor is not affected.

[0038] When the motor is required to control the rotation of the first pinch roller 52, a magnetic field is generated by activating the electromagnetic coil. This magnetic field can cause a mechanical connection between the input end and the output end, so that the input end and the output end are connected together, so that the motor can realize the forward and reverse control of the central axis of the first pinch roller 52. When the motor control is completed, the electromagnetic coil can be turned off to cut off the magnetic field, so that the input end and the output end are separated, and the influence of the motor on the first pinch roller 52 is stopped.

[0039] It is understandable that when the silk thread is tangled and wound around the first clamping roller 52, the electromagnetic clutch can be used to drive the first clamping roller 52 to rotate forward or reverse, so as to facilitate the processing of the tangled wire rope and further improve the practicality.

[0040] A spline sleeve 521 and a spline shaft 522 are respectively provided at both ends of the middle break of the first pressing roller 52, the spline shaft 522 and the spline sleeve 521 are detachably connected, and the first pressing roller 52 is slidably provided at the end of the through hole 511. It can be understood that the provision of the spline sleeve 521 and the spline shaft 522 facilitates the installation of the first pressing roller 52 on the connecting frame 51.

[0041] In summary, the braiding machine clamping device of the embodiment of the utility model can simultaneously clamp the wire rope and the guide roller separately through the provided clamping mechanism, and can adapt to wire ropes of different thicknesses, thereby ensuring the smooth operation of the guide roller and the wire rope and improving the practicability of the device.
