Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, and particularly relates to an automatic adjusting device for a sleeve. Background Art

[0002] The sleeve is an important component of a double-sided circular knitting machine, mainly used for adjusting the left and right positions of the upper and lower cams and the height positions of the upper and lower needle cylinders. Therefore, the sleeve needs to be able to perform two movements relative to the large tripod, namely rotational movement and vertical movement.

[0003] Existing technology: The rotational movement is adjusted by an elephant trunk assembly. The vertical movement is driven by a small gear to rotate a large gear, and the lifting is carried out through the helical pair between the large gear and the sleeve.

[0004] Defect: To achieve automatic adjustment on the basis of the existing technology, at least 3 motors are required. Moreover, the adjustment process is relatively complex. Especially for the automatic adjustment of the elephant trunk assembly, continuous forward and reverse correction is required, which poses relatively high requirements for control technology. Summary of the Utility Model

[0005] The utility model provides an automatic adjusting device for a sleeve to solve the technical problems existing in the above-mentioned existing technology. It is convenient to use, and only one motor is needed to realize the rotational movement and vertical movement of the sleeve.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] An automatic adjusting device for a sleeve includes a large tripod, a sleeve, a motor, a motor gear, a limiting mechanism, a rotating mechanism, and a lifting mechanism. The sleeve is installed in the inner hole of the large tripod. The motor is installed on the large tripod. One end of the motor is provided with a motor gear. The rotating mechanism includes a sun gear, a planetary carrier, outer disk A, and a coil. The lifting mechanism includes outer disk B. The motor drives the sun gear to rotate. The outer disk A and the outer disk B are arranged in cooperation. The limiting mechanism and the planetary carrier are arranged in cooperation.

[0008] The limiting mechanism includes a cylinder housing, a cylinder rod, a spring, and a limiting block. The cylinder rod is arranged in the cylinder housing. One end of the cylinder rod is a spring, and the other end is a limiting block. One side of the limiting block is provided with a vertical groove. The outer side of the planetary carrier is provided with a vertical groove, which is arranged in cooperation with the vertical groove of the limiting block.

[0009] The cylinder housing is provided with an exhaust port and a vent hole.

[0010] The rotating mechanism further includes a planetary gear and a bushing. The sun gear, the planetary gear, and the outer disk A form a planetary gear mechanism. The bushing is tightly installed with the planetary carrier. When the planetary gear rotates around the central group of the sun gear, it drives the planetary carrier to rotate. When the planetary carrier rotates, the sleeve rotates.

[0011] The lifting mechanism further includes an intermediate gear, a large lifting gear, and a pressing plate. The rotation of the outer wheel disc B drives the rotation of the intermediate gear, which in turn drives the rotation of the lifting gear. The large lifting gear is threadedly connected to the sleeve, and the pressing plate is arranged in cooperation with the large lifting gear.

[0012] A method of using an automatic adjustment device for a sleeve. When the rotational movement of the sleeve needs to be achieved, the limiting mechanism is ventilated, the cylinder rod retracts backward, the limiting block withdraws from its function, enabling the planet carrier to rotate. At the same time, the coil needs to be de-energized, that is, the outer wheel disc A and the outer wheel disc B are in a separated state, and the rotation of the outer wheel disc A does not drive the rotation of the outer wheel disc B. At this time, the intermediate gear and the large lifting gear do not rotate, and the gear action path is: motor gear - sun gear - planet gear - outer wheel disc A.

[0013] A method of using an automatic adjustment device for a sleeve. When the lifting of the sleeve needs to be achieved, the limiting mechanism is not ventilated, the cylinder rod extends forward, the limiting block acts on the planet carrier, making the planet carrier unable to rotate and only able to move up and down. At the same time, the coil is energized, and the coil and the outer wheel disc A form an electromagnet to adsorb the outer wheel disc B on the outer wheel disc A. At this time, the outer wheel disc A and the outer wheel disc B are in a state of synchronous rotation, and the gear action path is: motor gear - sun gear - planet gear - outer wheel disc A - outer wheel disc B - intermediate gear - large lifting gear.

[0014] Adopting the solution of the present utility model, only one motor is required to achieve the rotation and lifting of the sleeve, reducing the complexity of control. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0020] The following is combined with Figure 1 - Figure 4 for further description:

[0021] An automatic adjustment device for a sleeve, comprising a large tripod 1, a sleeve 2, a motor 3, a motor gear 4, and a limiting mechanism 5 (cylinder housing 51, cylinder rod 52, spring 53, limiting block 54), a rotating mechanism 6 (sun gear 61, planet gear 62, planet carrier 63, bushing 64, outer disc A 65, coil 66), and a lifting mechanism 7 (outer disc B 71, intermediate gear 72, lifting large gear 73, pressing plate 74).

[0022] The sleeve 2 is installed in the inner hole of the large tripod 1 and can rotate and lift.

[0023] The motor 3 is installed on the large tripod 1, the motor gear 4 is installed on the motor 3, and the motor 3 drives the motor gear 4 to rotate, thereby driving the sun gear 61 to rotate.

[0024] The limiting mechanism 5 includes a cylinder housing 51, a cylinder rod 52, a spring 53, and a limiting block 54. The limiting mechanism 54 is installed on the large tripod 1, and several limiting mechanisms 5 are evenly distributed around the central axis of the large tripod 1. The cylinder rod 52 is fixedly connected to the limiting block 54. The cylinder rod 52 is installed in the cylinder housing 51, and the spring 53 is installed at the bottom of the cylinder rod 52 to push the cylinder rod 52 to extend outwards. In the case of no air supply, the cylinder rod 52 acts on the planet carrier 63 through the limiting block 54 under the action of the spring 53. There are vertical grooves 57 on both the limiting block 54 and the planet carrier 63. When the limiting block 54 acts on the planet carrier 63, the vertical grooves 57 on the limiting block 54 and the planet carrier 63 are embedded and restricted with each other, ensuring that the planet carrier 63 cannot rotate but can move up and down. In the case of air supply, the cylinder rod 52 contracts inwards against the thrust of the spring 53. At this time, the limiting block does not act on the planet carrier 63, and the planet carrier 63 can rotate.

[0025] The rotating mechanism 6 includes a sun gear 61, a planet gear 62, a planet carrier 63, a bushing 64, an outer disc A 65, and a coil 66.

[0026] The sun gear 61, the planet gears 62 and the outer disk A65 form a planetary gear mechanism. When the sun gear 61 rotates, the planet gears 62 rotate around their own axes and at the same time rotate around the central axis of the sun gear 61.

[0027] The bushing 64 is tightly fitted and installed on the planet carrier 63. There are several bushing mounting holes evenly distributed around the central axis of the planet carrier 63.

[0028] The planet gears 62 are installed in the bushings 64, and the number is the same as the number of bushing mounting holes on the planet carrier 63.

[0029] When the planet gears 62 rotate around the central axis of the sun gear 61, they drive the planet carrier 63 to rotate. The planet carrier 63 is connected to the sleeve 2 by screws. The rotation of the planet carrier 63 means the rotation of the sleeve 2, thus realizing the rotational movement of the sleeve 2.

[0030] The lifting mechanism 7 includes an outer disk B71, an intermediate gear 72, a large lifting gear 73 and a pressing plate 74.

[0031] The rotation of the outer disk B71 drives the intermediate gear 72, thereby driving the large lifting gear 73 to rotate.

[0032] The large lifting gear 73 and the sleeve 2 have threads and are connected by threads.

[0033] Due to the action of the pressing plate 74, the large lifting gear 73 does not move in the vertical direction.

[0034] Therefore, when the large lifting gear 73 rotates, the sleeve 2 is lifted and lowered through the threads between the large lifting gear 73 and the sleeve 2.

[0035] The outer disk A65 and the coil 66 form an electromagnet structure. When the coil 66 is not energized, the outer disk A65 has no magnetism, and the outer disk A65 and the outer disk B71 are in a separated state. The rotation of the outer disk A65 does not affect the outer disk B65. At this time, the outer disk B71 is in a power-off state. When the coil 66 is energized, the outer disk A65 has magnetism and adsorbs the outer disk B71. At this time, the outer disk A65 and the outer disk B71 are in a state of synchronous rotation.

[0036] When it is necessary to realize the rotational movement of the sleeve 2, the limiting mechanism 5 is ventilated, the cylinder rod 52 retracts backward, the limiting block 54 withdraws from its function, and the planet carrier 63 can rotate. At the same time, the wire needs to be de-energized, that is, the outer disk A65 and the outer disk B71 are in a separated state, and the rotation of the outer disk A65 does not drive the outer disk B71 to rotate. At this time, the intermediate gear 72 and the large lifting gear 73 do not rotate. The gear action path is: motor gear 4 - sun gear 61 - planet gears 62 - outer disk A65.

[0037] When it is necessary to realize the lifting of the sleeve 2, the limiting mechanism 5 is not ventilated, the cylinder rod 52 extends forward, and the limiting block 54 acts on the planet carrier 63, so that the planet carrier 63 cannot rotate and can only move up and down. At the same time, the coil 66 is energized, and the coil 66 and the outer disk A 65 form an electromagnet to adsorb the outer disk B 71 on the outer disk A 65. At this time, the outer disk A 65 and the outer disk B 71 are in a state of synchronous rotation. The gear action path is: motor gear 4 - sun gear 61 - planet gear 62 - outer disk A 65 - outer disk B 71 - intermediate gear 72 - lifting large gear 73.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
