Description

Convex disc propelling and anti-channeling device of ring spinning frame
Technical Field
The invention belongs to the technical field of ring spinning frames, and particularly relates to a convex disc propelling and anti-channeling device of a ring spinning frame.
Background
In the field of current textile machinery, an automatic collective doffing system equipped on a ring spinning frame relates to a cam conveying method, and a 'pusher dog pushing a cam' is widely applied to the collective doffing system of the spinning frame due to the reasons of simple structure, easy maintenance and the like.
The stay bar moves back and forth alternately under the action of power, and the supporting claw pushes the convex disc to advance. The structure only has the function of preventing the convex disc from retreating when the supporting claw advances. The convex disc can not be prevented from overshooting forwards under the action of external force, and when the supporting claw retreats, the convex disc can shift forwards and backwards under the action of the external force, and no device is used for limiting the convex disc. The position of the stop of the cam should be fixed with respect to the fixed spindle position on the spinning frame, otherwise a misalignment occurs when the colony system exchanges empty and full bobbins with the main frame of the spinning frame. Therefore, a suitable mechanism is required to prevent the cam from accidentally moving.
Disclosure of Invention
The invention aims to overcome the defects of the original structure in the technical background and provide a convex disc propelling and anti-channeling device of a ring spinning frame in a collective doffing system of the ring spinning frame, wherein the convex disc propelling and anti-channeling device and the convex disc propelling and anti-channeling device are organically combined, and the anti-channeling device does not influence the advancing of the convex disc and can also prevent the convex disc from accidentally shifting forwards and backwards. A complex and difficult-to-control device is not additionally introduced, and the anti-channeling device is designed by utilizing the gravity and the lever principle just like the supporting claw principle.
In order to achieve the purpose of the invention, the technical scheme is as follows:
a convex disc propelling and anti-channeling device of a ring spinning frame comprises a convex disc propelling device, a convex disc anti-propelling device and a convex disc anti-reversing device.
Furthermore, the convex disc propelling device comprises a guide rail, a convex disc, a stay, a supporting claw and a first pin shaft, wherein the convex disc is arranged in a guide rail groove of the guide rail, the guide rail is fixedly arranged on the spinning frame, and the supporting claw is arranged on the stay through the first pin shaft. The stay moves forwards to drive the supporting claw to move forwards, the front end of the supporting claw is contacted with the convex disc and pushes the convex disc to move forwards, when the stay moves backwards, the upper ridge line of the supporting claw is contacted with the bottom surface of the convex disc, the supporting claw rotates around the first pin shaft, when the stay and the supporting claw are separated from contact, the front end of the supporting claw is light and the rear end of the supporting claw is heavy, and due to gravity, the front end of the supporting claw can be automatically lifted.
Furthermore, the convex disc anti-feeding device comprises a bearing seat, a second pin shaft, a bearing, an anti-feeding hook, a third pin shaft and a first limit pin shaft, wherein the bearing is arranged on the bearing seat through the second pin shaft, the bearing seat is arranged on the stay, the anti-feeding hook is rotatably arranged on the guide rail through the third pin shaft, and the first limit pin shaft positioned on one side of the anti-feeding hook is arranged on the guide rail. The bearing frame is fixed to be set up on the stay, prevent into the hook because the action of gravity emptys forward, and receive the restriction of first spacing round pin axle, when the stay reachs forefront position, the stay moves forward to the bearing and prevents into the contact of vertical plane under the hook, the outer lane face of cylinder promotion of bearing prevents into hook anticlockwise rotation, and until the up end pushes up the face of cylinder of protruding dish bottom, thereby the jack-up prevents into the hook messenger and prevents into the hook and withstands protruding dish and prevent its drunkenness forward, when the stay is followed forefront position backward motion, the stay moves backward to the bearing and prevents into the hook and no longer contacts, because the action of gravity, prevent into the hook and topple clockwise, break away from the contact with the protruding dish, no longer play prevents into the effect, thereby it is unimpeded when making the protruding dish move forward.
Furthermore, the convex disc tilting prevention device comprises a second limit pin shaft, a tilting prevention claw, a fourth pin shaft and a third limit pin shaft, the tilting prevention claw is rotatably arranged on the guide rail through the fourth pin shaft, the second limit pin shaft positioned on one side of the tilting prevention claw is arranged on the guide rail, the third limit pin shaft positioned on the other side of the tilting prevention claw is arranged on the guide rail, and under the action of gravity, the tilting prevention claw rotates anticlockwise around the fourth pin shaft to touch the second limit pin shaft and is limited by the second limit pin shaft, the front end of the tilting prevention claw tilts up, and the convex disc is prevented from falling back; when the supporting claw pushes the convex disc forwards, the lower bottom surface of the convex disc presses the ridge line of the anti-falling supporting claw, so that the anti-falling supporting claw rotates clockwise, the convex disc is not blocked from advancing, and once the lower bottom surface of the convex disc is not in contact with the ridge line of the anti-falling supporting claw, the anti-falling supporting claw automatically resets to an anti-falling state under the action of gravity.
Furthermore, the supporting claw, the anti-advance hook and the anti-back claw all contribute to gravity reset. The anti-falling claw is passively prevented from falling, the anti-entering hook is actively prevented from entering, the most front position of the supporting claw is a normal state, and the falling is an instant state.
The invention has the beneficial effects that: a supporting claw in a ring spinning frame convex disc propelling and anti-channeling device is only used as the power of a convex disc, and the anti-reverse supporting claw can prevent the convex disc from backing up under external force and prevent an advancing hook from being supported by an outer ring of a bearing, so that the convex disc can be prevented from overshooting; when the colony system pushes the full bobbin and the empty bobbin is replaced on the convex disc, the convex disc is strictly forbidden to be dislocated to wait for the spinning frame and the colony system to carry out empty bobbin exchange, and at the moment, as long as the power source of the stay keeps the stay at the most advanced position, the convex disc can be in a fixed position under the combined action of the anti-back claw and the anti-advance hook, so that the play is avoided; when the colony system exchanges empty pipes and full pipes with a bobbin winder or a pipe sorting and dropping mechanism, the anti-falling supporting claw only prevents the convex disc from moving backwards, and the anti-falling hook prevents the convex disc from overshooting when the supporting claw pushes the convex disc each time; when the convex disc needs to be replaced, the stay only needs to be moved to the position where the anti-entering hook is separated from the bearing, and then the convex disc can be manually pushed forwards.
