Abstract
The utility model relates to a safety protection device for a button attaching machine. The device is characterized in that the device comprises a ring sleeved outside a movable mould, a limit switch and an electromagnetic lock, wherein, the ring moves in linkage with a swing stem and a pedal pull rod, the limit switch is used for detecting the position of the swing stem, and the electromagnetic lock is used for limiting the action of the pedal pull rod. When the device is in operation, a user treads on a pedal to pull the pedal pull rod (6), and the pull rod (6) pulls the swing rod (2) with the ring (1) to fall; the ring (1) is used for detecting whether hand is present below the movable mould (3); and without descending of the ring (1), the limit switch (4) is impossible to take action and to enable the electromagnetic lock (5) to be electrified, so that the pedal pull rod (6) is locked and ceases to continue moving down, the movable mould (3) is impossible to fall down, and safety of personnel can be ensured. The device ensures accurate detection, and the work efficiency remains as high as before.
Description
Technical field
The utility model relates to a kind of safety guard of button-sewing machine, and it is mainly used in garment processing industry.
Background technology
The a large amount of use a kind ofly pounded the button-sewing machine of clasp to clothes in the clothes processing enterprise, and this button-sewing machine in use causes unexpected injury through regular meeting because the workman is careless and inadvertent, and taking place maximum is to smash workman's finger, gives personal and property all causes damage.
For addressing this problem, people have developed some safety guards.For example: name is called the utility model of pneumatic single head button-sewing machine, and its application number is: 200620140979, and this utility model is to be provided with the photoelectric protection switch near the stationary rivet die position, is used for detecting the position of staff.This device has the following disadvantages: staff need leave near the punch die during operation, can not help workpiece well, and this can influence the nail catcher quality, the more important thing is and has reduced production efficiency.
Summary of the invention
The purpose of this utility model provides a kind of safety guard of button-sewing machine, and its reliable operation ensures the safety of the person effectively, and does not influence the operating efficiency of button-sewing machine after installing and using.
The purpose of this utility model is achieved in that it comprises a ring that is enclosed within the dynamic model outside, and ring and fork thereof and the interlock of foot-operated pull bar have a limit switch to detect the fork position, and the action of the foot-operated pull bar of electromagnetic lock restriction is arranged.Like this, when the people steps on the foot-operated pull bar of pedal pulling, at first spur fork to lower swing, if ring is fallen then fork shake-up limit switch of normal position, limit switch is switched on to electromagnetic lock, makes foot-operated pull bar release, continues to move downward, spur clutch pull rod simultaneously and move downward together, movable punch die is moved downward clasp is pounded.
Description of drawings
Accompanying drawing is the structural representation of an embodiment of the present utility model.In the accompanying drawings, (1) is ring, and (2) are the forks of ring, and (3) are dynamic models, and (4) are limit switches, and (5) are electromagnetic locks, and (6) are foot-operated pull bars, and (7) are clutch pull rods.
The specific embodiment
In the present embodiment, ring (1) is enclosed within the outside of dynamic model (3), ring (1) is fixed on the fork (2), fork (2) under the pulling of foot-operated pull bar (6) to lower swing, limit switch (4) is used for detecting the position of fork (2), and electromagnetic lock (5) is used for locking foot-operated pull bar (6) and makes it not stretchy clutch pull rod (7).
During work, with two parts up and down of clasp respectively after putting well on dynamic model and the cover half, the moving pedal that tramps with one's feet, foot-operated pull bar (6) promptly moves downward, pulling fork (2) and encircle (1) and together move downward.At this moment, if dynamic model (3) does not have foreign matter (as: staff) on every side, then fork (2) can touch limit switch (4), connecting power supply makes electromagnetic lock (5) electricly will ride pull bar (6) release, allow it to continue to move downward, pulling clutch pull rod (7) finally makes dynamic model (3) move downward, and finishes the nail catcher action.If dynamic model (3) has foreign matter (as: staff) on every side; then ring (1) can be risen by the foreign matter pad; fork (2) just can not touch limit switch (4); electromagnetic lock (5) can not get yet; foot-operated pull bar (6) will no longer be continued to move downward by locking, and clutch pull rod (7) can be not pulled down yet; dynamic model (3) just can not pounded down, has therefore just protected operator's personal safety.
Claims (1)
- A kind of safety guard of button-sewing machine is characterized in that: it comprises a ring that is enclosed within the dynamic model outside, and ring and fork thereof and the interlock of foot-operated pull bar have a limit switch to detect the fork position, and the action of the foot-operated pull bar of electromagnetic lock restriction is arranged.
