1 is a perspective view showing a pizza water clamping device for an embroidery machine according to an embodiment of the present invention.

As illustrated in FIG. 1, the pizza water clamping device 100 for an embroidery machine according to an embodiment of the present invention includes a unit body 110, a support unit 120, a lever 130, and an elastic member 140. 2 and 3), and the clamping operation unit 150 may be included.

The unit body 110 is installed on a workbench (not shown) of the embroidery machine (not shown). For this purpose, a plurality of fixing holes 114 may be formed in the workbench to be fixed to the workbench. In addition, the unit body 110, the support unit 120 is arranged side by side with each other slidably coupled in the interval direction between the support unit 120, the fixing bolt 112 is fastened to the support unit 120 is screwed A plurality of fastening holes 113 may be formed in the gap direction. Therefore, the interval between the unit body 110 may be appropriately adjusted according to the size or shape of the pizza water according to the position selection of the fastening hole 113 fastened using the fixing bolt 112.

The unit body 110 may have a sliding groove 111 formed along its longitudinal direction for sliding engagement with the sliding protrusion 126 formed on the bottom surface of the support unit 120.

The support unit 120 is coupled to the plurality of unit bodies 110 at intervals, and has a support 121 for supporting the lower side of the pizza water. Here, the support unit 120 may be made in a pair as in the present embodiment, it is not limited to this may be made in various numbers depending on the type of pizza water or the number of simultaneous processing. In addition, the cover 125 of the elastic material may be fitted to reduce the slippage of the pizza water to the front side of the support 121 and to prevent damage to the pizza water.

The support unit 120 is coupled to the unit body 110 and is provided on the upper end of the support portion 122 and the support portion 122 is provided so as to face the lower side of the lever 130 by extending the support 121 forward The lever 130 is hinged by the lever hinge shaft 132, the lever coupling portion 123 for supporting the end of the elastic member 140 for elastically supporting the lever 130, and the lever coupling portion 123 It is provided on the top, it may include a clamping operation installation unit 124, the clamping operation unit 150 is installed.

The lever 130 is rotatably installed on the upper side of each of the support units 120 so as to pressurize and depressurize the support 121 from the upper side downward with the pizza water therebetween. Therefore, the support unit 120 and the lever 130 are formed in at least two pairs so as to clamp the sides of the pizza water, respectively, whereby embroidering for the portion located between the support unit 120 of the pizza water Be sure to For this embroidery machine, it is possible to employ a known embroidery machine will be omitted.

The lever 130 is hinged to the support unit 120 via the lever hinge shaft 132, the hinge coupling portion 131 provided at the rear end, so as to be rotatably installed on the support unit 120.

The lever 130 may be formed to be bent downward toward the front end for the stable clamping of the pizza water, and the cover 133 of the elastic material is fitted to prevent the pizza water from slipping and to prevent damage to the pizza water. Can lose.

The elastic member 140 (shown in FIGS. 2 and 3) is installed in each of the support units 120 to provide an elastic force so that the lever 130 is depressurized from the support 121. For example, the elastic spring 140 may be formed of a coil spring. .

The clamping manipulation unit 150 is installed on each of the support units 120, and the lever 130 presses the support 121 by the user's manipulation or releases the pressure by the elastic force of the elastic member 140.

Clamping operation unit 150 is an operating tip 151 hinged to the support unit 120 so that the upper end is rotatable back and forth, as in this embodiment, and the support unit so that the front and rear can rotate up and down through the operation tip 151 back and forth Rotating member 153, the rear end is hinged to the 120, and both ends are hinged to the operation tip 151 and the rotation member 153, respectively, and the rotation member 153 according to the front and rear rotation of the operation tip 151 ) Is provided to extend downward to the link member 155 and the rotating member 153 to be fixed by rotating upward and downward, and press the lever 130 according to the upper and lower rotation of the rotating member 153. It may include a pressing member 158 for releasing and pressing.

The operation tip 151 is hinged to the support unit 120 by the first hinge shaft 152 so that the upper end is rotatable back and forth in a state perpendicular to the support unit 120, in order to improve the feeling of operation on the top. The cover 159 may be provided.

The rotating member 153 penetrates back and forth through the gap formed in the longitudinal direction of the operation tip 151, and the rear end is hinged to the upper end of the support unit 120 by the second hinge shaft 154 (shown in FIGS. 2 and 3). Coupled, thereby allowing the shear to rotate up and down about the second hinge axis 154.

The link member 155 is hinged by the third hinge shaft 156 at a point where the front end is located forward of the second hinge shaft 154 in the rotation member 153, and the rear end is formed by the operation tip 151. The first hinge shaft 157 is hinged to a point located above the first hinge shaft 152. Therefore, as shown in FIG. 2, when the user rotates the operation tip 151 forward, the link member 155 rotates the rotation member 153 forward, so that the pressing member 158 of the lever 130 By pressing the hinge coupler 131 downward, the support 120 and the lever 130 are brought into close contact with each other with the pizza water interposed therebetween, thereby allowing the pizza water to be clamped. Meanwhile, when the operation tip 151 is rotated forward, the third hinge axis 156 and the fourth hinge axis 157 are positioned on the same vertical line, or the fourth hinge axis 157 is the third hinge axis 156. By being located in the front compared to the operation tip 151 is prevented from rotating to the rear unless a constant force is applied, thereby allowing the lever 130 to keep the support 121 pressed downwards.

As shown in FIG. 3, when the user rotates the operation tip 151 backward, the link member 155 rotates the rotation member 153 backward, so that the pressing member 158 is spaced apart from the lever 130. Then, the lever 130 is returned by the elastic member 140 in the direction away from the support 121 to release the clamping for the pizza water.

The pressing member 158 is fixed by a plurality of nuts 158a to be coupled up and down to the front end of the rotating member 153, thereby adjusting the height of the nut 158a according to the fastening point of the nut 158a. And, it is fixed to the lower end of the height adjustment nut (158b), and may include a buffer member (158c) made of a material having elasticity.

According to such a pizza water clamping device for embroidery machines according to the present invention, as shown in Figure 2, the pizza water is clamped between the support 121 and the lever 130 by the operation of the clamping operation unit 150, As shown in FIG. 3, the shearing of the lever 130 is increased by the opposing operation of the clamping operation unit 150 and the elastic force of the elastic member 140, so that the pizza water between the supporter 121 and the lever 130 is increased. Allow clamping to be released.

Therefore, the pizza water can be easily clamped or de-clamped only by a user's operation, and the pizza water can be clamped accurately and stably by improving reliability of the pizza water clamping operation.
