Abstract

Disclosed is a clamp device capable of automatic opening and closing. A position-adjusting support is fixed on a fixed support, a clamp-opening handspike is moveably connected to the position-adjusting support via a screw shaft and rotates around the screw shaft, and a position-limiting board is fixed on the position-adjusting support and forward-and-backward moves with the position-adjusting support according to the diameter of a button to act position-limiting function to a position-limiting shaft. The position-limiting is tightly fixed on a slide carriage of a clamping jaw, and the movements of the position-limiting shaft can drive the slide carriage of the clamping jaw to move. The forward-and-backward movements of the slide carriage enable the opening and closing of the clamp. A presser rod is disposed right above the clamp-opening handspike and is fixed on a straight rod. The utility model reduces unnecessary accidents and increases operational efficiency. Further, the utility model has the advantages of safety, reliability, and wide application.

Description

Automatic folding clip device

The utility model relates to button attaching machine clip structure Design and manufacturing technology.

At present, the used button attaching machine clip of clothes processing industry is to make two clip pawls produce inside clamping force by spring to come the clamping button substantially, usually in advance the spacing of two clip pawls is adjusted to less than the button diameter according to the size of button diameter, outer rim by button when putting into button struts two clip pawls, after finishing the nail seam, the cloth around pull-button is buckled hauls out button come.The size of the spring force on the clip is very important, when spring force is big, picks and places the button difficulty, and draws bad dress material easily when taking out button; Spring force hour, the vibration that produces when clip falls easily causes accidents such as broken needle, broken button.And in fact no matter to select much little spring forces, all keep away unavoidable above-mentioned two kinds of situations and take place.

The purpose of this utility model provides a kind ofly has a big clamping force in the process of nail catcher, and when picking and placeing button this power is eliminated, and reduces unnecessary accident, the automatic folding clip device of raising operating efficiency.

The purpose of this utility model is to realize like this, constitute by fixed mount, clip pawl slide, clip pawl and spring, it is characterized in that: position adjustable rack is fixed on the fixed mount, opening the folder lever is movably connected on the position adjustable rack by the spiral shell axle, opening the folder lever can rotate around the spiral shell axle, limiting plate is fixed on the position adjustable rack, move forward and backward with position adjustable rack according to the button diameter, limit shaft is played position-limiting action, limit shaft is fastened on the clip pawl slide, the mobile clip pawl slide that can drive of limit shaft moves, and slide moves forward and backward and will make clip pawl closure and open.Open the folder lever directly over for depression bar, depression bar is fixed in the vertical rod.

The utility model has the advantages that: can increase spring pressure, to guarantee to the button chucking power, button does not rotate unshift between the clip pawl when clip falls and in the mop motion, finish nail seam back by lifting being used to make every effort to overcome and obeying this spring force, two clip pawls are opened of clip, can not only handled easily, and safe and reliable.The nail seam was a kind of earlier when the button of nail seam different-diameter in the past, the nail seam is another kind of again after adjusting two jaw spacings, button diameter as the collar button of shirt and other positions is different, collar button is wanted little 1mm, if press the spacing between the collar button adjustment clip pawl, then when the button at other positions of nail seam, button will occur putting and get the difficult thing of button, but behind this device, the spacing of clip pawl can be adjusted to than the big 1-2mm of big button diameter, when nail seam collar button, also can clamp button like this, thereby can raise the efficiency.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model Fig. 1 vertical view.

Fig. 3 is the existing clip structural representation of the utility model.

This automatic folding clip device, as shown in Figure 1, 2, 3, constitute by fixed mount, clip pawl slide, clip pawl and spring, it is characterized in that: position adjustable rack 7 is fixed on the fixed mount 8, open folder lever 1 and be movably connected on the position adjustable rack 7 by spiral shell axle 3, limiting plate 5 is fixed on the position adjustable rack 7, and limit shaft 4 is fastened on the clip pawl slide 11, open the folder lever directly over for depression bar 2, depression bar is fixed in the vertical rod 6.Usually button attaching machine clip device when driving falls, shown in Fig. 1 solid line part; The clip device lifts during parking, shown in Fig. 1 dotted line.This device has utilized This move realization folding clip pawl just.During driving, opening folder lever 1 breaks away from depression bar 2, be subjected to pressure two clip pawls, the 10 inside clampings of spring 9 and drive clip pawl slide to move forward till clamping button, open folder lever 1 this moment and be pushed into horizontal level by limit shaft 4, when stopping, clip lifts, and opens folder lever 1 and runs into depression bar 2 around 3 rotations of spiral shell axle, promote limit shaft 4 clip pawl slide is moved backward, the clip pawl opens.Depression bar 2 is adjusted according to actual conditions, and generally when depression bar was depressed out the folder lever, the spacing of two clip pawls should be greater than the 1-2mm of button diameter; When two jaws clamp button, between limiting plate 5 and the limit shaft 4 the 0.5-1mm spacing should be arranged.Spring adopts big elastic spring, helps to clamp button.Adopt the common machine process technology just can produce.
