In the prior art, most of the top stops of zippers have achieved automation. For example, a Chinese utility model patent with the publication number CN209732766U discloses an automatic installation device for metal zipper particles top stops. This device realizes the automatic feeding of the top stops through the cooperation of an upper clamping knife, a lower clamping knife and a telescopic die, and pushes the upper clamping knife and the lower clamping knife to the stamping structure through a first motion device to realize automatic stamping, thereby realizing the automatic installation of the top stops.

[0003] However, when processing some special products, a semi-automatic zipper top stop machine is still needed. Although there are also semi-automatic zipper top stop machines in the prior art, the effects are not very ideal.

[0025] The following further describes the specific embodiments of the present invention in conjunction with the drawings of the specification, making the technical solutions and their beneficial effects of the present invention clearer and more definite. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] The additional aspects and advantages of the present invention will become apparent in the following description section or be learned through the practice of the present invention.

[0027] Referring to Figures 1 - 5 As shown, a semi-automatic zipper top stop machine includes a stamping assembly 1, an upper pressing die 2, a forming upper die 3, a lower fixed die 4, and a lower pressing die 5; the stamping assembly 1 includes a stamping power mechanism 1-1 and a stamping rod 1-2, and the stamping rod 1-2 moves up and down under the drive of the stamping power mechanism 1-1; the upper pressing die 2 is connected to the stamping rod 1-2 through an upper return spring 6 to form a lifting and reset connection, the forming upper die 3 is fixed to the stamping rod 1-2, the forming upper die 3 penetrates through the upper pressing die 2 and forms an upper accommodating cavity 7 with the upper pressing die 2 in the natural state of the upper return spring 6; the lower fixed die 4 is fixed to the base 8, the lower pressing die 5 is connected to the base 8 through a lower return spring 9 to form a lifting and reset connection, the lower fixed die 4 penetrates through the lower pressing die 5 and forms a lower accommodating cavity 10 with the lower pressing die 5 in the natural state of the lower return spring 9.

[0028] The working principle of the above semi-automatic zipper top stop machine is as follows: 1) Place the top stop in the lower accommodating cavity 10, and hold the zipper tape to be installed with the top stop on the lower pressing die 5; 2) Start the stamping assembly 1, and the stamping power mechanism 1-1 drives the stamping rod 1-2 to punch downward. During the downward punching process, the upper pressing die 2 first contacts and presses the zipper tape with the lower pressing die 5. As the stamping rod 1-2 continues to move downward, the upper pressing die 2 moves upward, the lower pressing die 5 moves downward, and the forming upper die 3 presses the top stop with the lower fixed die 4 to realize the stamping and riveting of the top stop and the zipper tape; 3) After stamping is completed, the pressing power mechanism 1-1 drives the stamping rod 1-2 to move up and down. When starting the upward movement process, the forming upper die 3 and the lower fixed die 4 are first separated, and then the upper pressing die 2 and the lower pressing die 5 are separated, and the zipper tape with the installed top stop is taken out to complete the stamping of the top stop.

[0029] Compared with the prior art, a semi-automatic upper stop machine for zippers provided in this embodiment can position the upper stop piece through the lower accommodation cavity 10 and the upper accommodation cavity 7 when stamping the upper stop. During the stamping process, the zipper tape can be fixed by the upper pressing die 2 and the lower pressing die 5, and the effect of stamping the upper stop of the zipper is better by arranging the mutually cooperating upper pressing die 2, forming upper die 3, lower fixed die 4 and lower pressing die 5.

[0030] Combined with Figure 1 , Figure 2 As shown, the stamping die is further provided with an anti-pinch safety switch 11. When the anti-pinch safety switch 11 detects that a human hand enters, the stamping assembly 1 does not perform the stamping action, thereby ensuring the safety of the stamping operation. The anti-pinch safety switch 11 can be selected from existing known photoelectric switches, infrared induction switches, etc. The specific model selection and control circuit design of the anti-pinch safety switch 11 are common technical knowledge mastered by those skilled in the art and will not be elaborated here.

[0031] In this embodiment, preferably, the anti-pinch safety switch 11 is in three groups and is arranged on the left and right sides and the rear side of the stamping die, so as to avoid pinching hands to the greatest extent. Obviously, the specific number of groups and positions of the anti-pinch safety switch 11 can be adjusted by those skilled in the art according to actual needs and are not limited to this embodiment.

[0032] In this embodiment, the stamping power mechanism 1-1 is preferably a cylinder. In some embodiments, the stamping power mechanism 1-1 can be other existing known or future realizable power mechanisms such as an oil cylinder, and is not limited to this embodiment.

In some embodiments, the upper guide rods 12 and the lower guide rods 13 can be omitted, and the forming upper die 3 and the lower fixed die 4 can be directly used for guiding, which is not limited to this embodiment.

[0034] In some embodiments, the lower fixed die 4 and the lower pressing die 5 are detachably connected to the base 8, such as by bolt or screw connection; so as to replace the different lower pressing dies 5 according to different actual needs, and further meet the upper stop stamping and riveting requirements of different shapes and different models.
