Technical Field

[0001] The utility model relates to the technical field of leather goods, in particular to a trimming device for cutting leather goods. Background Art

[0002] Leather cutting refers to the process of cutting leather materials into designed shapes. The specific operation is to use the cardboard as a template, lay the leather materials on it, mark the positions to be cut, and then use the leather trimming device, which usually refers to the leather trimming machine, which can be used to cut sandpaper, leather, cloth and other materials that need trimming, and the trimming is neat and without burrs.

[0003] However, the existing trimming device is inconvenient to adjust when trimming leather goods, resulting in different trimming gaps on both sides required for different leather goods, poor trimming applicability, and poor efficiency of common single-side trimming. Therefore, we propose a trimming device for leather cutting. Utility Model Content

[0004] In view of the above problems, the utility model provides a trimming device for leather cutting, which has an adjusting effect to prevent the inconvenience of adjusting the size of the leather and poor applicability when trimming the leather. At the same time, it has a limiting effect to prevent the leather from being skewed when trimming the leather.

[0006] In a further technical solution, mounting blocks are fixedly connected at the four corners of the upper surface of the trimming device base, and the mounting blocks are in a group of two. The two groups of mounting blocks are respectively located on both sides of the first mounting plate, and a connecting plate is provided on the side where the two mounting blocks are close to each other, and the lower surface of the connecting plate is rotatably connected to a limiting roller.

[0007] In a further technical solution, the patterns of the two spiral patterns are opposite to each other, and the contact surface between the fixing block and the working groove is smooth and fitted.

[0008] In a further technical solution, the limiting roller is made of rubber material, the limiting roller is in close contact with the leather material, and a working room is opened on the surface of the mounting block.

[0009] In a further technical solution, a telescopic rod fixedly connected to the connecting plate is fixed to the inner wall of the working chamber, and a spring is sleeved on the surface of the telescopic rod.

[0010] In a further technical solution, two ends of the spring are fixedly connected to the working chamber and the connecting plate respectively.

[0011] The beneficial effects of the utility model are:

[0012] 1. The rotating rod, spiral pattern, fixed block and driving motor cooperate with each other, so that the trimming knife body can be adjusted when trimming the leather material. The driving motor drives the rotating rod to rotate, so that the rotating rod can cooperate with the spiral pattern thread transmission fixed block to move away from or close to each other, achieving an effect of easy adjustment, preventing the trimming knife body from being inconvenient to adjust when trimming the leather material, affecting the use experience;

[0013] 2. The mounting block, connecting plate and limiting roller cooperate with each other, so that the base of the trimming device can be easily limited when placing the leather material. By pulling the connecting plate away from the mounting block, the limiting roller can apply force to the surface of the leather material to limit the position, thereby achieving the effect of facilitating the limiting position and preventing the inconvenience of limiting the position when trimming the leather material, which may easily cause skewness and affect the trimming effect.

[0020] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0021] Example:

[0022] like Figure 1-Figure 4 As shown, a trimming device for cutting leather goods comprises a trimming device base 1 and a first mounting plate 2, a second mounting plate 3 and a trimming knife body 4. The first mounting plate 2 is fixed on both sides of the trimming device base 1, the second mounting plate 3 is slidably connected to the surface of the first mounting plate 2 through a driving device, the trimming knife body 4 is arranged in pairs on the lower surface of the second mounting plate 3, and the lower surface of the second mounting plate 3 is provided with an operating groove 5, in which a rotating rod 6 is rotatably connected, and the surface of the rotating rod 6 is provided with two spiral patterns 7 distributed in pairs, and the surface of the spiral pattern 7 is threadedly connected with a fixing block 8 fixed to the trimming knife body 4, the patterns of the two spiral patterns 7 are opposite to each other, and the contact surface of the fixing block 8 and the operating groove 5 is in a fitted and smooth state, and a driving motor 9 is fixedly connected to one side of the second mounting plate 3, and the output shaft of the driving motor 9 is fixedly connected to the rotating rod 6.

[0023] The working principle of the above technical solution is as follows:

[0024] When it is necessary to cooperate with the edge cutting of leather materials of different sizes placed on the surface of the trimming device base 1, the leather material can be placed on the surface of the trimming device base 1 first, and then the driving motor 9 can be started to drive the rotating rod 6 to rotate, so that the rotating rod 6 can move the fixed block 8 through the spiral pattern 7. At this time, since the patterns of the two spiral patterns 7 are opposite to each other, the fixed block 8 can be adjusted to move away from or close to each other when being driven, so that it can be adjusted according to the required size of the leather material. Subsequently, the second mounting plate 3 is driven by the driving device to move downward to cut the edge of the leather material, thereby achieving the effect of facilitating the adjustment of the gap and preventing the trimming knife body 4 from being inconvenient to adjust the leather size during use, resulting in poor overall trimming efficiency and poor applicability.

[0025] In another embodiment, if Figure 1 and Figure 3 As shown, mounting blocks 10 are fixedly connected at the four corners of the upper surface of the trimming device base 1. The mounting blocks 10 are grouped into two, and the two groups of mounting blocks 10 are respectively located on both sides of the first mounting plate 2. A connecting plate 11 is provided on the side where the two mounting blocks 10 are close to each other. The lower surface of the connecting plate 11 is rotatably connected to a limiting roller 12, which is made of rubber and is in a fit with the leather material. A working room 13 is opened on the surface of the mounting block 10, and a telescopic rod 14 fixedly connected to the connecting plate 11 is fixed to the inner wall of the working room 13. A spring 15 is sleeved on the surface of the telescopic rod 14, and the two ends of the spring 15 are respectively fixedly connected to the working room 13 and the connecting plate 11.

[0026] When it is necessary to limit the leather material for trimming the surface of the trimming device base 1, first, the connecting plate 11 can be held by hand to apply force to move away from the mounting block 10, and then the leather material can be placed on the surface of the trimming device base 1, and then the leather material can be held by hand to pass between the limiting roller 12 and the facing surface of the trimming device base 1. At this time, the limiting roller 12 can be in contact with the surface of the leather material. At the same time, since the material of the limiting roller 12 is rubber, the limiting roller 12 applies friction to the leather material to prevent the leather material from shifting and tilting. At the same time, the telescopic rod 14 and the spring 15 can cooperate to apply tension. When the limiting roller 12 applies pressure to the leather material, pressure can be applied through the elastic force of the telescopic rod 14 and the spring 15, so that both sides of the leather material are subjected to outward pulling force to prevent the leather material from tilting, thereby achieving the effect of facilitating limiting and preventing the inconvenience of limiting when trimming the leather material, which may easily affect the trimming effect.

[0027] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
