[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] The designer of this utility model has innovatively proposed an elastic presser foot for sewing machine pressers, which can simulate the effect of manual pressing, reduce damage to the template by the presser foot, and is suitable for sewing templates with varying thicknesses, thereby improving the efficiency and quality of the sewing machine.

[0021] like Figures 1 to 6 As shown, a spring-loaded pressure foot for a mold carrier includes a flat-bottomed bowl-shaped pressure foot 1 fixed on the mold carrier. The pressure foot 1 has a square through hole 4 in the middle. The pressure foot 1 has a pressure foot mounting hole 5 at one corner of the square through hole 4. The bottom of the pressure foot 1 has a symmetrically arranged spring-loaded pressure plate mechanism on each side of the square through hole 4. The spring-loaded pressure plate mechanism includes a fixed plate 9 and a spring-loaded pressure plate 2 arranged sequentially from top to bottom at the bottom of the pressure foot 1. The top surface of the spring-loaded pressure plate 2 has three inverted L-shaped support feet 3. Each support foot 3 has a spring in its vertical part 13. The bottom of the pressure foot 1 has two sets of grooves symmetrically arranged on both sides of the square through hole 4, corresponding to the three support feet 3. The lower part of the support foot 3 slides up and down through the fixed plate 9, and the upper part is set in the groove of the corresponding groove group. The top of the spring in the support foot 3 is in contact with the groove. The support foot 3 slides up and down in the groove by the spring. When the spring is relaxed, the horizontal part 14 of the upper part of the support foot 3 is in contact with the upper surface of the fixed plate 9.

[0022] The groove group includes a first groove 6, a second groove 7, and a third groove 8 from left to right. The first groove 6, the second groove 7, and the third groove 8 are arranged in a triangle, and the first groove 6 and the third groove 8 are on the same straight line. The three support feet 3 are arranged in a triangle corresponding to the groove group. The three support feet 3 arranged in a triangle can make the elastic pressure plate 2 press the template more stably, so that the template is pressed evenly and the template damage is reduced.

[0023] The fixing plate 9 is flat on one side near the square through hole 4, and has three opening slots 10 corresponding to the groove group on the other side. The vertical part 13 of the support foot 3 is set in the opening slot 10, and the horizontal part 14 is connected to the upper surface of the fixing plate 9.

[0024] The fixing plate 9 is connected to the pressure foot 1 by an adjusting screw 11, which is located between the first groove 6 and the second groove 7. The extension range of the elastic pressure plate 2 is adjusted by adjusting the distance between the fixing plate and the bottom of the pressure foot 1.

[0025] The first groove 6 and the third groove 8 have openings 12 on one side of the square through hole 4.

[0026] The elastic pressure plate 2 is semi-circular, with the two elastic pressure plates 2 having their arc surfaces facing outwards, their planes facing each other, and being arranged on both sides of the square through hole 4.

[0027] Before use, insert the presser foot rod of the mold conveyor into the presser foot mounting hole 5, and fix the presser foot 1 to the presser foot rod by passing screws through the fixing hole of the presser foot 1.

[0028] When in use, the presser foot rod of the mold moving machine moves downward, driving the presser foot 1 to press the template. The elastic pressure plate 2 is under pressure, compressing the spring upward. The horizontal part of the support foot 3 moves away from the upper surface of the fixed plate 9. The degree of upward compression of the spring varies depending on the thickness of the template. When the same template has different thicknesses, the pressure on the template can be adjusted by the two elastic pressure plates 2 respectively, simulating the effect of manual pressing.

[0029] The beneficial effects of the above-mentioned structure are as follows: The elastic pressure foot of the mold conveying machine provided by the present invention, by setting an elastic pressure plate at the bottom of the pressure foot, allows the pressure on the template during the operation of the mold conveying machine to be automatically adjusted in real time by the extension and contraction of the spring, simulating the effect of manual pressing by a person, thereby improving the efficiency and quality of the mold conveying machine.

[0030] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
