Description

Technical Field

[0001] The utility model relates to the field of leather cutting in the shoe industry, in particular to a leather stretching machine assisting manual leather inspection. Background Art

[0002] Before leather is used directly, it needs to go through an inspection process to confirm whether there are any defects in the leather. Leather with defects will affect the appearance of the finished product.

[0003] The conventional inspection method is to stretch the leather manually, which requires the cooperation of multiple people to stretch the leather. However, the leather is large in area and heavy, which requires a high level of strength from the operators. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a leather stretching machine that assists manual leather inspection, which can support the leather and stretch it out, replacing the laborious method of manual stretching.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A leather stretching machine for assisting manual leather inspection is characterized in that the main body has a lifting part and a spreading part extending outward from both sides of the lifting part, and the lifting part and the spreading part are provided with clips for clamping the leather, and the leather is stretched or spread out by unfolding.

[0007] Furthermore, the lifting part includes a lifting frame and a push rod movably connected to the lifting frame, and the push rod has a moving direction that is the same as that of the lifting frame.

[0008] Furthermore, both the expanded portion and the lifting frame have a supporting surface for supporting the leather, and the holes provided on the supporting surface are connected to the clips.

[0009] Furthermore, the lifting frame and the support portion are both in the shape of a triangular prism.

[0010] Furthermore, the main body includes a base frame, and the base frame is provided with an electric push rod for pushing the lifting frame to move.

[0011] Furthermore, the expanded portion is a side frame, and the side frame is suspended above the base frame.

[0012] Furthermore, a transverse push cylinder is provided on both sides of the lifting frame, and the side frames are connected to the plug rods of the transverse push cylinders.

[0013] Furthermore, a first guide assembly, a second guide assembly, and a third guide assembly are provided. The base frame is connected to the lifting frame through the first guide assembly, the lifting frame is connected to the side frame through the second guide assembly, and the lifting frame is connected to the top rod through the third guide assembly to guide each activity direction to remain horizontal or vertical.

[0014] Beneficial effects of the utility model:

[0015] The leather stretching machine of the present invention is used to assist in the inspection of leather. The cooperation of the lifting part, the stretching part and the clamp is mainly to make the leather straight. In this way, it is convenient to observe the leather with the naked eye, and defects can be easily found on the leather. In addition, there is no need for operators to squat to observe, and in terms of labor, fatigue is relatively reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] See also Figure 1-5 As shown, a leather stretching machine for assisting manual leather inspection includes a base frame 1, a lifting frame 2 and a side frame 3. The lifting frame 2 is movably assembled on the base frame 1 and can move in the Y direction along the base frame 1. Relatively, the side frame 3 is movably assembled on the lifting frame 2 and can move in the X direction along the base frame 1.

[0022] It can be seen that according to the two activities in the Y direction and the X direction, this leather stretching machine has two states: expanded and contracted. In the contracted state, the leather is directly placed on the leather stretching machine, and the area of ​​the leather is larger than the support surface a of the leather stretching machine used to support the leather. When switching to the expanded state, the overall size of the leather stretching machine becomes larger through outward movement in the Y direction and the X direction. Similarly, the area covered by the support surface a on the leather also becomes larger. The leather fixed to the support surface a by a clip (not shown in the figure) is naturally pulled and eventually reaches a taut state.

[0023] An electric push rod 100 is provided on the base frame 1 , and a lifting unit of the electric push rod 100 is connected to the lifting frame 2 , so that the electric push rod 100 performs the lifting and lowering movement of the entire lifting frame 2 .

[0024] On both sides of the lifting frame 2, there are transverse pushing cylinders 21, and the side frames 3 are connected to the plug rods of the transverse pushing cylinders 21, and the transverse pushing cylinders 21 are used to realize the unfolding of the leather in the X direction.

[0025] The side frame 3 is suspended above the base frame 1 .

[0026] A plurality of holes b are provided on the supporting surfaces a of the lifting frame 2 and the side frame 3, and the clips can be installed on the holes b.

[0027] In order to further improve the tightening effect, a push rod 5 is provided on the top of the lifting frame 2. The push rod 5 is arranged horizontally. A lifting cylinder 4 is provided in the lifting frame 2 for use with the push rod 5. The extension method of the lifting cylinder 4 is the same as the moving direction of the lifting frame 2. After the leather is laid on the push rod 5, it falls onto the supporting surface a on the lifting frame 2 and the side frame 3. The push rod 5 serves as secondary lifting to reduce the load on the electric push rod 100.

[0028] In the embodiment, a plurality of guide assemblies 6 are further provided, the base frame 1 is connected to the lifting frame 2 through the first guide assembly, the lifting frame 2 is connected to the side frame 3 through the second guide assembly, and the lifting frame 2 is connected to the top rod 5 through the third guide assembly, guiding each movable direction to remain horizontal or vertical.

[0029] Furthermore, both the lifting frame 2 and the side frame 3 are in the shape of a triangular prism, which has a better effect in stretching the leather.

[0030] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
