[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0034] This embodiment relates to a quick die changing device for a pattern machine, the overall structure of which is as follows: Figure 1 As shown in , the rapid mold changing device of the pattern machine includes a mounting seat 1, a pressing plate 2, a limiting member 3 and a first elastic member 4. Among them, a mounting groove 5 is provided on the mounting seat 1, and the pressing plate 2 is slidably arranged in the mounting groove 5 along the up and down directions. A receiving groove 6 for the template of the pattern machine to extend into is formed between the pressing plate 2 and the mounting groove 5. A retraction groove 7 is provided on the side wall of the mounting groove 5, and the limiting member 3 is slidably arranged in the retraction groove 7. The first elastic member 4 is connected between the limiting member 3 and the mounting seat 1. Under the elastic action of the first elastic member 4, the limiting member 3 extends out of the retraction groove 7. When the pressing plate 2 slides downward, it can push the limiting member 3 back into the retraction groove 7 and press the template. The limiting member 3 can pop out under the action of the first elastic member 4 and limit the movement of the pressing plate 2.

[0035] It can be understood that in this embodiment, the template is limited by pressing the template with the pressing plate 2, and the movement of the pressing plate 2 is limited by the limiting member 3. When a new template needs to be loaded, the pressing plate 2 is driven to move downward to pass the limiting member 3 and press the template. The operation is simple. When the old template needs to be removed, the limiting member 3 is driven back to the retraction groove 7 and the pressing plate 2 is driven to move upward. The removal is convenient, which is beneficial to improving the replacement efficiency of the template and thus improving the production efficiency of the pattern machine.

[0036] It should be noted that, after the pressing plate 2 is pressed against the template, the limiting member 3 can limit the displacement of the pressing plate 2 by making the bottom of the limiting member 3 press against the top of the pressing plate 2 .

[0037] Based on the overall introduction above, as a preferred implementation, in this embodiment, a limiter 3 is provided on the side walls on both sides of the installation groove 5, and the first elastic member 4 is provided in a one-to-one correspondence with the limiter 3. Such a configuration is conducive to ensuring the stability of the pressing plate 2 when pressing the template, and is conducive to improving the accuracy of subsequent sewing patterns. As shown in the figure, a limiter 3 is provided on each of the side walls on both sides. Of course, only one limiter 3 is provided on each side wall, which is also only a preferred implementation. In addition, in other embodiments, the number of limiters 3 can also be two, three, four, etc.

[0038] As a preferred example, Figure 1 and Figure 6 As shown in , in this embodiment, the limiting member 3 has a limiting portion 301 for limiting the movement of the pressing plate 2, and a guide portion 302 connected to the limiting portion 301 at one end away from the mounting groove 5. The guide portion 302 is arranged through the side wall of the mounting groove 5, and the first elastic member 4 includes a first spring sleeved on the guide portion 302. Such an arrangement has a simple structure and is convenient to set. In addition, in order to prevent the limiting member 3 from blocking the downward movement of the pressing plate 2, an inclined abutment surface 16 is provided at the bottom of the limiting portion 301. When the pressing plate 2 moves downward, the abutment surface 16 contacts the pressing plate 2, so that the pressing plate 2 can push the limiting member 3 back to the retraction groove 7.

[0039] In addition, as a preferred implementation, Figure 2 As shown in , a rotating disk 8 is provided at the rear of the mounting base 1, a first connecting rod 9 is hinged on the rotating disk 8, a connecting rod 10 is provided on the guide portion 302, and the connecting rod 10 is hinged with the first connecting rod 9. When the rotating disk 8 is driven to rotate, the rotating disk 8 can drive the limiting member 3 to move left and right through the first connecting rod 9 and the connecting rod 10. In this arrangement, the driving structure is simple, and by rotating the rotating disk 8, the limiting members 3 on both sides can be controlled to return to the retraction groove 7, which is easy to operate.

[0040] A connecting column for the first connecting rod 9 is provided on the turntable 8, and two connecting columns are arranged at intervals along the circumference of the turntable 8. The two connecting columns are respectively hinged to the two first connecting rods 9, and the two first connecting rods 9 are respectively hinged to the connecting rods 10 on the guide parts 302 on both sides. A handle 17 is provided on the turntable 8, and the turntable 8 can be driven to rotate by the handle 17, which is convenient to operate.

[0041] In addition, as a preferred embodiment, a slide plate 11 is provided on the side wall at the rear side of the installation groove 5 and is slidably arranged in the front-rear direction, and a second connecting rod 12 is hinged between the slide plate 11 and the pressing plate 2. The slide plate 11 can be pushed backward by the template, and the pressing plate 2 is driven to move downward through the second connecting rod 12. In this way, during the process of loading the template, the template pushes the slide plate 11 to move backward, and then drives the pressing plate 2 to move downward, so that the pressing plate 2 presses the template tightly, and there is no need to set up a separate device for driving the template to move downward. The structure is simple, the operation is convenient, the cost is low, and during the process of loading the template, the downward movement and pressing action of the pressing plate 2 can be performed synchronously, which is conducive to improving the installation efficiency of the template.

[0042] When implementing it, Figure 2 and Figure 5 As shown in the figure, the slide plate 11 is arranged through the side wall on the rear side of the mounting seat 1, and in order to facilitate the hinge connection between the pressure plate 2 and the second connecting rod 12, the rear side of the pressure plate 2 is provided with a connecting end 18 extending backward from the mounting seat 1, the connecting end 18 is hinged with the second connecting rod 12, and in order to facilitate the connecting end 18 to move up and down with the pressure plate 2, an avoidance groove 15 for avoiding the up and down movement of the connecting end 18 is provided on the mounting groove 5.

[0043] As a preferred embodiment, as shown in the figure, in this embodiment, a guide rod 13 extending backward is provided on the mounting seat 1, and a guide hole matching the guide rod 13 is provided on the slide plate 11. Such a configuration is conducive to improving the stability of the slide plate 11 when it moves forward and backward. In specific implementation, guide rods 13 are provided on the mounting seat 1 at positions on both the left and right sides of the slide plate 11.

[0044] As a preferred implementation, in this embodiment, a second elastic member 14 is connected between the slide plate 11 and the mounting seat 1. Under the elastic action of the second elastic member 14, the slide plate 11 can move forward and drive the pressing plate 2 to move upward through the second connecting rod 12. Figure 2 and Figure 4 As shown in , the second elastic member 14 can be a second spring sleeved on the guide rod 13, one end of the second spring is connected to the slide plate 11, and the other end of the second spring is connected to the mounting seat 1, with a simple structure and convenient arrangement. By providing the second elastic member 14, when the template needs to be taken out, after the limit members 3 on both sides are retracted into the retraction groove 7, the slide plate 11 can move forward under the elastic action of the second elastic member 14, and drive the pressing plate 2 to move upward through the second connecting rod 12, so that the pressing plate 2 releases the pressure on the template, and the slide plate 11 can push the template forward, which is convenient for taking out the template.

[0045] The fast mold changing device for the pattern machine of this embodiment can realize the positioning of the template by clamping the template together with the bottom of the groove of the installation groove 5 by the pressing plate 2. When the template needs to be replaced, the turntable 8 is rotated so that the turntable 8 drives the limit members 3 on both sides to return to the retraction groove 7 through the first connecting rod 9 and the connecting rod 10 on both sides, and then the slide plate 11 can move forward under the action of the second elastic member 14, and the slide plate 11 drives the pressing plate 2 to move upward, thereby releasing the pressing on the template and taking out the template.

[0046] When a new template is loaded, the template can push the slide plate 11 to move backward, and the slide plate 11 can drive the pressure plate 2 to move downward through the second connecting rod 12, so that the template can be clamped after passing through the limiting member 3, thereby realizing the positioning of the template. At the same time, the limiting member 3 pops out under the elastic action of the first elastic member 4, which can limit the displacement of the pressure plate 2 and ensure the stable limiting of the template by the pressure plate 2.

[0047] The quick die-changing device for the pattern machine of this embodiment realizes the position limitation of the template by pressing the template with the pressing plate 2, and limits the movement of the pressing plate 2 by the position limiting member 3, which facilitates the removal of the old template and the installation of the new template, and is conducive to improving the efficiency of template replacement, thereby improving the production efficiency of the pattern machine. In addition, by providing a turntable 8 and making the turntable 8 rotatably connected with the position limiting members 3 on both sides, it is convenient to realize the control of the movement of the position limiting members 3. And by providing a slide plate 11 and making the slide plate 11 and the pressing plate 2 transmission connection, it is conducive to further improving the installation efficiency of the template.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
