Description

A reinforcing and sewing device for the upper and sole of labor protection shoes

Technical Field

The invention relates to the technical field of sewing equipment, in particular to a device for reinforcing and sewing the upper and sole of a labor protection shoe.

Background Art

When producing labor protection shoes, in order to improve production efficiency, a sewing machine is usually used to sew the sole and the upper together. The sole is fixed by setting a shifting component that can lay the sole flat and fix it on the processing table of the sewing machine. After the user manually places the upper on the sole, the needle of the sewing machine sews the sole and the upper together. In order to improve the sew effect of the sole and the upper, a multi-directional sew process is usually used for sew processing. Therefore, when the sole and the upper are sewed obliquely, the user needs to hold the sole and the upper and push them at the needle of the sewing machine for sew. Since both the upper and the sole need to be held by the user, when the sole is impacted by the sewing machine needle, the sole is easily caused to slip out of the user's hand, thereby causing injury to the user.

Referring to Figures 4 and 5, a switch assembly is provided between the two lower notches 44 for regulation, and the switch assembly includes a pull rod 62 and two support ear plates 61. The two support ear plates 61 are respectively fixedly connected to the outside of the two fixed beams 40, and the two sides of the two support ear plates 61 facing each other are rotatably connected to the outside of the two rotation shafts 60. The two ends of the pull rod 62 are respectively rotatably connected to the outside of the two rotation shafts 60. The pull rod 62 is configured to be a U-shaped rod, and the side of the pull rod 62 away from the rotation shaft 60 is placed inside the two lower notches 44.

Working principle:

When in use: the first step is to place the sole inside the placement groove 31, rotate the second screw 32 to drive the circular plate 33 to spirally transmit inside the circular groove 34, and the second screw 32 drives the circular plate 33 and makes the support plate 35 approach the two sides of the sole, and fix the sole inside the placement groove 31 by respectively fitting the support plates 35 in the support components on both sides to the two sides of the outside of the sole.

In the second step, the mounting plate 30 is rotated and drives the connecting plate 22 and the cross beam 21 to rotate between the two side plates 20 with the cross plate 24 as the center. The rotation of the mounting plate 30 drives the sole to tilt after being fixed, so that the sole is placed in an inclined state under the needle of the sewing machine body 10, and the first screw 25 is rotated toward the surface of the cross plate 24 outside the hanging plate 26. The first screw 25 presses the cross plate 24 outside the side plate 20 to fix the angle of the cross beam 21 after rotation. Since the sole is fixed inside the placement groove 31, the upper is placed outside the sole at this time, and the needle of the sewing machine body 10 sews the upper and the sole together, and the mounting plate 30 drives the connecting plate 22 to slide outside the cross beam 21 to push the sole and the upper to be sewed together in a continuous manner, and the sole is positioned by rotation.

The third step is to place the upper on the sole after fixing the sole inside the placement groove 31, and then generate elastic force on the two pressure columns 41 through two elastic ropes 45, and the two pressure columns 41 press the head and tail of the sole respectively, flatten the head and tail of the sole inside the placement groove 31, and fix the sole longitudinally at the same time.

The fourth step is to sew the sole and one side of the upper together, and then pull the pull rod 62 upward with the rotating shaft 60 as the center. The pull rod 62 pushes and drives the two top plates 43 to move upward. The top plates 43 move upward to drive the pressure column 41 to separate from the sole, thereby achieving the effect of quickly removing the sole and the upper from the placement slot 31.

The fifth step is to separate the one-way pressing assembly from the sole by controlling the switch assembly, then pull the mounting plate 30 upward and drive the connecting roller 51 to move the first rotating plate 52 inside the inner notch 54. The movement of the first rotating plate 52 causes the sleeve spring 53 to shrink inside the inner notch 54, and at the same time, the connecting roller 51 drives the clamping plate 55 to move out of the clamping groove 56. At this time, the mounting plate 30 can be rotated outside the connecting plate 22, and after the connecting roller 51 rotates one hundred and eighty degrees, the clamping plate 55 is re-engaged into the clamping groove 56. At this time, the mounting plate 30 drives the sole to rotate half a circle outside the connecting plate 22, and then the other side of the sole is rotated to below the needle head of the sewing machine body 10.

The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
