[0020] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The drawings provide embodiments of the device. However, the device can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "set" should be understood in a broad sense, for example, they can be fixedly connected or set, or detachably connected or set, or integrally connected or set. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] Example 1

[0023] like Figure 1 As shown, this embodiment provides a kind of Laban equipment for the production of labor protection shoes, including a Laban machine 2 and a car plate frame 1, the car plate frame 1 controls the Laban machine 2 through the pedal at the bottom, it should be noted that the Laban machine 2 has the same structure as the existing Laban machine on the market, the clutch motor controlled by two pedals drives the hook mechanism to work through the belt, and the manual wheel on the side is used to adjust the height of the presser foot at the feeding port, such as the existing 600 Laban machine, which will not be described in detail here;

[0024] A chute I5 corresponding to the feeding port is provided at the extension platform 3 of the working surface of the rabang machine 2, and a clamping mechanism 4 for clamping is clamped inside the chute I5;

[0025] The clamping mechanism 4 includes two threaded rods I41 movably connected to the inside of the slide groove I5 through the slider I6. It should be noted that when movably connected to the inside of the slide groove I5, the slider 6 itself should be provided with a limiter to ensure the fixation of its own position. For example, a positioning pin is provided at the slider I6 to match the positioning holes equidistantly opened on the inner wall of the slide groove I5. The slider I6 can also be directly fixed to the inside of the slide groove I5 or use other methods such as an electric guide slider;

[0026] The top of the threaded rod I41 is sleeved with a threaded tube I42 connected by a thread, and the two threaded tubes I42 are respectively located on the left and right sides of the crochet mechanism of the Labang machine 2, and their function is to adjust and adapt the upper and lower positions according to the height of the presser foot, which can be achieved by rotation; a limiting plate 43 is fixed on the top of the threaded tube I42, and a slide groove II45 is provided on the top of the limiting plate 43. The interior of the slide groove II45 is respectively connected to the columns 44 through two clamping sliders II. The two columns 44 located at the same limiting plate 43 are connected by an adjustment mechanism for adjusting the spacing between the two columns 44 to achieve clamping operation. The tops of the two columns 44 are both threadedly fixed with connecting plates 481, and the working surfaces of the two connecting plates 481 for clamping are both installed with clamping plates 482, that is, the top of the column 44 is provided with a thread, and the bottom end of the connecting plate 481 is provided with a matching screw groove, and the two are threadedly connected. When the column 44 rotates to the top of the screw groove, the clamping plate 482 should be in the clamping working direction;

[0027] In detail, the working surface of the clamping plate 482 is provided with a stepped groove, and the clamping plate 482 is movably connected to the slot 484 opened in the adjacent connecting plate 481 through the plug rod 483, and the clamping plate 482 is made of a magnetic material, and the inner wall of the slot 484 is inlaid with an iron sheet for magnetic adsorption. When the two stepped grooves are close to each other to clamp the fabric, there is a relatively large friction force, which plays a high clamping stability, and the role of the magnet and the iron sheet can ensure that when in use, the clamping plate 482 and the slot 484 are adsorbed by magnetic force to prevent it from falling off;

[0028] The adjusting mechanism includes two threaded rods II46 respectively fixed to the columns 44 at the same limit plate 43, and the two threaded rods II46 are connected by a threaded joint 47 which is threadedly connected therebetween, and the thread direction and pitch of the threaded rod II46 and the inner circle of the threaded joint 47 are adapted to each other. When the threaded joint 47 is rotated clockwise, the two threaded rods II46 are approached to each other, that is, the two clamping plates 482 are brought close to each other, and the clamping operation is realized. Conversely, when the threaded joint 47 is rotated counterclockwise, the two threaded rods II46 are moved away from each other, that is, the two clamping plates 482 are moved away from each other, and the finished product can be removed after the Labang operation is completed.

[0029] Example 2

[0030] The difference from Example 1 is that Figure 4 As shown, the clamping plate 482 and the inserting rod 483 are both arc-shaped.

[0031] It should be noted that the clamping plates 482 in Example 1 and Example 2 are only different in shape, and are used to adapt to the requirements of the tongue, upper or toe and heel flaps according to actual needs. That is, during production, the present flap equipment includes the two clamping plates 482 of different shapes in Example 1 and Example 2, which can be replaced by subsequent workers when needed.

[0032] It should be noted that the structure described in the utility model can be implemented in a variety of different forms and is not limited to the described embodiments. Any equivalent transformations made by ordinary technicians in this field using the contents of the utility model specification and drawings, or directly or indirectly applied to other related technical fields, such as the loading and unloading of other items, are included in the protection scope of the utility model.
