Embodiment 1

[0032] Please focus on reference figure 2 , figure 2 Schematic diagram of the structure of the safety shoes provided by the embodiment of the present invention. Such as figure 2 As shown, the embodiment of the invention provides a kind of safety shoes, and the safety shoes include:

[0033] The upper part 10 includes a shoe inner 11 and a shoe upper 12, the shoe upper 12 is wrapped outside the shoe inner 11, the shoe upper 12 and the shoe inner 11 except the part near the toe and the part near the sole The part of 40 is not bonded, and the other parts are bonded together;

[0034]A midsole plate 20, which is connected to the part of the shoe inner lining 11 close to the sole 40;

[0035] Toecap 30, which is placed outside the part of the shoe inner 11 near the toe and bonded together with the part of the shoe inner 11 near the toe, except for the part of the shoe upper 12 near the toe that is near the sole 40 All other parts are bonded to the outside of the toe cap 30 ...

Embodiment 2

[0048] The part of the inner lining 11 of the safety shoes provided in this embodiment is close to the sole 40 and the edge of the midsole plate 20 is stitched together by seaming process, and the structure of the rest of the safety shoes provided in this embodiment is the same as that of the safety shoes in the first embodiment above. The structure is the same, and will not be repeated here.

[0049] Please focus on reference Figure 4 , Figure 4 The flow chart of the manufacturing method of the safety shoes provided by Embodiment 1 of the present invention, such as Figure 4 As shown, the method for manufacturing the safety shoes provided in the embodiment of the invention comprises:

[0050] Step 1: Wrap the formed shoe upper 12 outside the shaped shoe inner 11, place a hot-melt adhesive sheet 13 between the shoe upper 12 and the shoe inner 11 near the heel, between the shoe upper 12 and the shoe inner 11 These three are bonded together by applying glue between them, an...

Embodiment 3

[0056] The shoe inner 11 and the midsole plate 20 of the safety shoes provided by this embodiment are integrally formed to form a sock cover, and the structure of the rest of the safety shoes provided by this embodiment is consistent with the structure of the safety shoes in the above two embodiments, and will not be discussed here. Let me repeat.

[0057] Please focus on reference Figure 5 , Figure 5 The flow chart of the manufacturing method of the safety shoes provided by Embodiment 1 of the present invention, such as Figure 5 As shown, the method for manufacturing the safety shoes provided in the embodiment of the invention comprises:

[0058] Step 1: Wrap the molded vamp 12 outside the molded sock, place a hot-melt adhesive sheet 13 between the vamp 12 and the sock near the heel, apply glue between the vamp 12 and the sock to seal the three or bonded together, the part of the upper 12 near the sole 40 is longer than the bottom surface of the sock cover, and this par...

Abstract

The invention provides a safety shoe and a method for manufacturing the same, wherein the safety shoe comprises a shoe lining, a vamp, a middle sole plate, a toe cap and a sole, through sewing or bonding the shoe lining with the middle sole plate, the vamp and the sole are only needed to be sewn together in a sewing technology, so the problem that sewing holes are produced on the shoe lining because the vamp, the shoe lining and the sole are sewn together in the original sewing technology is solved, and the water leakage possibility of the safety shoe is reduced. Moreover, the method for manufacturing the safety shoe overcomes the problem that the vamp which is close to the toe cap part cannot be sewn on the sole in the original sewing technology, other sewing methods are adopted to sew the vamp part which is close to the sole with the side surface of the sole together, and the vamp is firmly fixed on the sole. The safety shoe cannot cause the vamp part which is connected with the sole to crack due to long-term use, cannot pollute the environment due to the use of glue, and has good air permeability.

Description

technical field [0001] The invention relates to a production process of footwear products, in particular to a safety shoe and a manufacturing method thereof. Background technique [0002] For safety footwear products with anti-smashing toe caps, safety indicators such as thickness, impact energy and static pressure must meet national safety standards. When in the upper of the shoe, the anti-smashing toe cap will make the front end of the shoe full and straight, and it is hard and not easy to deform. Therefore, it is not possible to sew the front end of the shoe after pressing down the toe cap. The current production on the market adopts the national safety standard. Most of the safety footwear products with anti-smashing toe caps are fixed on the part of the upper near the sole by glue coating or injection molding after putting on the toe cap, because the joint between the upper and the sole is the place where the wearer The part that is most likely to be pulled and worn ou...
