[0022] Example

[0023] like Figure 1-3As shown, a leather stretching and flattening device for leather product production proposed in one embodiment of the utility model comprises a skeleton 1, a bracket 2 is fixedly connected to the skeleton 1, a connecting rod 3 is fixedly connected to the upper end of the bracket 2, one end of the connecting rod 3 is rotatably connected to a pressure rod 4, one end of the pressure rod 4 is rotatably connected to a first rotating member 5, one end of the first rotating member 5 is rotatably connected to an auxiliary rod 6, one end of the auxiliary rod 6 is fixedly connected to a cover plate 7, a heating plate 8 is fixedly connected to the skeleton 1, a side plate 9 is fixedly connected to the outer wall of the bracket 2, one end of the side plate 9 is connected to a second rotating member 10, the second rotating member 10 is connected to a first electric push rod 11, the first electric push rod 11 is connected to the pressure rod 4 through a third rotating member 12, a connecting frame 13 is fixedly connected to one side of the skeleton 1, a second electric push rod 14 is fixedly connected to the connecting frame 13, an output end of the second electric push rod 14 is fixedly connected to a U-shaped frame 15, and a flattening roller 16 is provided on the U-shaped frame 15;

[0024] Frame 1 and bracket 2: constitute the basic framework of the device, providing support and fixation for other components.

[0025] Connecting rod 3 and pressing rod 4: The connection and rotation relationship between the two, in conjunction with the first electric push rod 11, can realize the pressing action of pressing rod 4 on the leather, which is helpful for stretching and preliminary flattening;

[0026] First rotating member 5, auxiliary rod 6 and cover plate 7: through the linkage of these components, the cover plate 7 can cooperate with the heating plate 8 to heat the leather and further improve the flattening effect;

[0027] Heating plate 8: used to heat the leather to make it easier to stretch and flatten, and to improve the performance of the leather;

[0028] The side plate 9, the second rotating member 10 and the first electric push rod 11 work together to drive the movement of the pressure rod 4 to achieve automatic control;

[0029] Connecting frame 13, second electric push rod 14, U-shaped frame 15 and flattening roller 16: the second electric push rod 14 pushes the U-shaped frame 15 and the flattening roller 16 to flatten the leather after heating and stretching to ensure flatness;

[0030] Pull rod 17: enhances the connection stability between the connecting rod 3 and the frame 1;

[0031] The special arrangement of the auxiliary rod 6 makes it more flexible during movement and does not contact the frame 1, thus avoiding unnecessary friction and interference.

[0032] The adaptation of the heating plate 8 and the cover plate 7 ensures the uniformity and effectiveness of heating;

[0033] The height design of the flattening roller 16 takes the thickness of the leather into consideration, and can better adapt to leathers of different thicknesses to achieve high-quality flattening operations.

[0034] like Figure 3 As shown, in some embodiments, one end of the connecting rod 3 is fixedly connected to the pull rod 17, and the pull rod 17 is fixedly connected to the frame 1; the stability and firmness of the connecting rod 3 can be enhanced. When the pressure rod 4 is rotating and applying force, the connecting rod 3 can always remain in a predetermined position, providing a stable support and rotation basis for the pressure rod 4. This helps to ensure the consistency of the stretching and flattening action and the stability of the effect.

[0035] like Figure 1 As shown, in some embodiments, one part of the auxiliary rod 6 is rotatably set on the bracket 2, and the bottom does not contact the frame 1; the auxiliary rod 6 is rotatably set on the bracket 2, which provides a clear fulcrum and guide for the movement of the auxiliary rod 6, so that it can rotate according to the designed trajectory and method, thereby accurately driving the cover plate 7 to complete the corresponding action, ensuring the accuracy of the cooperation between the cover plate 7 and the heating plate 8.

[0036] like Figure 3 As shown, in some embodiments, the shape and size of the heating plate 8 are adapted to the cover plate 7, and the area of ​​the cover plate 7 covers the heating plate 8. The shape and size adaptation of the heating plate 8 and the cover plate 7 ensures that a good seal can be formed when the cover plate 7 covers the heating plate 8, reducing heat loss and improving heating efficiency. In this way, heat can be transferred to the leather more quickly and evenly, which is beneficial to the stretching and flattening effect of the leather. The area of ​​the cover plate 7 covering the heating plate 8 can ensure that the heated area of ​​the leather is large enough and even during the heating process, avoiding the situation of insufficient or excessive local heating, so that the overall performance of the leather is more consistently improved.

[0037] like Figure 2 As shown, in some embodiments, the design height of the flattening roller 16 is higher than the horizontal height of the heating plate 8 to adapt to the thickness of the leather; when the design height of the flattening roller 16 is higher than the horizontal height of the heating plate 8, on the one hand, it can avoid unnecessary contact and collision between the flattening roller 16 and the heating plate 8 in the initial state or non-working state, thereby protecting the structural integrity of both. On the other hand, it can better adapt to leathers of different specific thicknesses.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
