Description

A carousel drive structure for beating button machine

Technical Field

The utility model relates to an automatic beat button machine field, concretely relates to carousel drive structure for beating button machine.

Background

Because the traditional mode of sewing the button with the needle thread is complex and is difficult to be produced mechanically, in modern clothes, the button fixedly connected with clothes in a riveting mode appears. The button generally comprises an upper button and a lower button, wherein the upper button and the lower button are riveted, and clothes are clamped between the upper button and the lower button to complete the fixation of the button.

The production of such buttons is generally carried out using: firstly, holes are punched in clothes, then the upper buckle and the lower buckle are aligned to the punched holes, and opposite impact force is applied to the upper buckle and the lower buckle, so that the upper buckle and the lower buckle are riveted and connected. In the traditional production, the production mode firstly uses a punching machine to punch holes, then takes the riveting machine to rivet, and has the defects of complex production process and low production efficiency.

In order to solve the problem that the production efficiency is low due to the fact that a plurality of machines are used for production, a button punching machine integrating a riveting device and a punching device exists in the prior art, and the button punching machine can achieve the purpose of simultaneously performing various kinds of processing by using the same machine through mutual moving switching of the riveting device and the punching device in a machine body.

However, in the button sewing machine of the prior art, the mutual switching between the riveting device and the punching device is usually performed by only using the air cylinder or the motor to perform direct driving, during the switching, the acceleration is large and the buffering device is lacked, the vibration of the whole machine body is large, and the motor or the air cylinder is suddenly started and stopped, so that the riveting device and the punching device are subjected to large acting force of the driving device during starting and stopping, and the riveting device and the punching device are easily damaged.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the existing button sewing machine integrating the riveting device and the punching device is large in overall weight, the riveting device and the punching device are switched by directly adopting an air cylinder, vibration generated when the riveting device and the punching device are switched is large, a buffering device is lacked, the acting force of the driving device is large when the riveting device and the punching device are switched, and the button sewing machine is easy to damage.

In order to solve the technical problem, the utility model provides a technical scheme as follows:

the utility model provides a carousel drive structure for beating button machine includes at least: a support; the rotary table is provided with a connecting shaft deviating from the rotating axis; the turntable driving device is used for driving the turntable to rotate around a rotating shaft center; the position that support and carousel are connected is equipped with and is used for holding the spread groove of connecting axle, the length direction of spread groove is perpendicular with the moving direction of support.

The principle of the scheme is that the frame is connected with the connecting shaft deviated from the rotating axis position on the turntable, and the connecting shaft is set to do circular arc or semicircular reciprocating motion between the limit positions at the left end and the right end of the turntable. Because the length direction of the connecting groove is vertical to the preset moving direction of the rack, the connecting shaft can only drive the bracket to move on a straight line vertical to the length direction of the connecting groove. In the rotating process of the connecting shaft, the speed direction of the connecting shaft is tangential to the rotating disc, so that the sub-speed of the connecting shaft in the direction perpendicular to the length direction of the connecting groove is gradually increased, the speed is maximized when the connecting shaft moves to the top end, and then the speed is gradually reduced. The speed of the frame is slow and the force is small when the frame is started and stopped, so that the turntable driving device can drive the upper driving block and the lower driving block to move and simultaneously provide a buffer function when the frame is started and stopped. It should be noted that the connecting groove leaves enough moving space for the connecting shaft in the vertical direction, so that the connecting shaft does not touch the wall surface of the connecting groove in the vertical direction, and the upper driving block and the lower driving block can be normally driven to move only in the horizontal direction without lifting the upper driving block and the lower driving block.

Preferably, the upper portion of support is equipped with the installation piece, be equipped with the mounting groove on the installation piece.

Furthermore, an upper riveting column and an upper punching column are arranged in the mounting groove, the upper riveting column is positioned on one side, close to the turntable driving device, of the mounting block, and the upper punching column is positioned on one side, far away from the turntable driving device, of the mounting block; and a reset mechanism is also arranged between the upper riveting column and the upper punching column and the mounting groove.

Furthermore, the lower part of the support is fixedly provided with a lower riveting column corresponding to the position coaxial with the upper riveting column, and the lower part of the support is fixedly provided with a lower punching column corresponding to the position coaxial with the upper punching column.

Furthermore, the upper end face of the lower riveting column is provided with a groove.

Preferably, a feeding push rod is arranged at a position, close to the mounting block, on the upper portion of the support, the extending direction of the feeding push rod is the same as the moving direction of the support, and the distance between the feeding push rod and the upper riveting column along the moving direction of the support is equal to the distance between the upper riveting column and the upper punching column along the moving direction of the support.

The utility model has the advantages that when the frame is started or stopped, the turntable driving device can provide a buffer function, prevent the larger impact force generated by the larger acceleration when the conversion step is started or stopped, reduce the abrasion of the frame, and have simple structure and convenient manufacture; meanwhile, the vibration generated by the rack can be reduced, so that the machine body is more stable when the button sewing machine with the structure is applied.
