Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, and more specifically to a polyurethane synthetic leather fast cutting machine. Background Art

[0002] Polyurethane synthetic leather is a specially treated synthetic material that is soft, wear-resistant and durable, and can simulate the touch and performance of natural leather. The cutting machine uses advanced cutting technology and equipment to quickly and accurately cut polyurethane synthetic leather materials into the shapes and sizes required for footballs, such as dough, patches, lines, etc., to meet the needs of football manufacturing.

[0003] Among them, it was found through searching that the utility model patent with patent application number CN201921945570.2 discloses an automatic leather cutting machine, a conveyor belt is arranged on the workbench, a pressing plate bracket is arranged at the feeding end of the conveyor belt, and a feeding pressing plate is fixed on the pressing plate bracket; a layout area is arranged on one side of the pressing plate bracket, a cutting bracket is arranged on one side of the layout area, an outer crossbeam and an inner crossbeam are arranged in parallel on the cutting bracket, and a cutting device is arranged on the inner crossbeam; the cutting device comprises a double-headed cylinder, a slider, a slide rail, a cutting knife holder, and a cutting knife;

[0004] When this structure is in use, the cut leather is placed on the feed pressing plate to be flattened and fixed, and then enters the layout area for layout. Manual layout is performed according to the shape of the parts to avoid defects. The leather is sent to the cutting bracket by the conveyor belt and the double-headed cylinder is started. The double-headed cylinder drives the sliders at both ends to slide back and forth on the slide rails, thereby realizing double-head cutting. However, this structure makes it difficult to cut multiple materials at one time during cutting, resulting in low cutting production efficiency. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides a polyurethane synthetic leather fast cutting machine, aiming to solve the problems raised in the above background technology.

[0006] The utility model is implemented in this way. The utility model provides the following technical solutions: a polyurethane synthetic leather fast cutting machine comprises a bottom plate for support, and a transmission cutting assembly is arranged on the top of the bottom plate;

[0007] The conveying and cutting assembly comprises a first stand arranged on the top of the bottom plate for support, and a second stand is arranged on one side of the first stand;

[0008] A first connecting shaft is movably connected to the first vertical frame, a second connecting shaft with adjustable position is arranged on the top of the first connecting shaft, a plurality of cutting dies for cutting are distributed on the outer side of the second connecting shaft and along the circumference of the axis point of the second connecting shaft, two first extension rods for support are arranged on the outer side of the first vertical frame, and a supporting wheel is arranged on the top of each of the first extension rods, and a lower hopper is arranged at the bottom of the base plate and between the first vertical frame and the first connecting shaft.

[0009] It can be seen that in the above technical solution, when the first connecting shaft rotates, the cutting die is driven to rotate, thereby realizing the function of cutting the material, and when the motor rotates, the third connecting shaft is rotated through the pulley and the belt, which is easy to transport the waste after cutting, and when the polyurethane synthetic leather is transported between the first connecting shaft and the second connecting shaft, the supporting wheels support both sides of the polyurethane synthetic leather, ensuring the stability of the polyurethane synthetic leather during transportation, thereby improving the quality during cutting;

[0010] Optionally, in a possible implementation, a third connecting shaft is provided on the second frame, a fourth connecting shaft is provided at the bottom of the third connecting shaft, a pulley is provided at one end of the third connecting shaft and the first connecting shaft, and each of the pulleys is connected by a belt transmission, a motor for driving the first connecting shaft to rotate is provided at one end of the first connecting shaft away from the pulley, sliders installed on the first frame are provided at both ends of the first connecting shaft, the sliders are slidably connected to the first frame, limiting rods installed on the first frame and slidably connected to the sliders are provided at the tops of the two sliders, and a spring sleeved on the limiting rods is provided at the tops of each of the sliders, two second extension rods for support are provided on the side of the second frame facing the first frame, and a supporting shaft is provided between each of the second extension rods;

[0011] It can be seen that in the above technical solution, the first connecting shaft is displaced upward by the top force when the material is placed. When the first connecting shaft is displaced upward, it drives the slider to move upward and compresses the spring. The elasticity of the spring itself drives the slider downward to apply pressure, so that the first connecting shaft and the second connecting shaft can be in close contact with the material.

[0012] Technical effects and advantages of the utility model:

[0013] By setting up the conveying and cutting assembly, compared with the prior art, the overall design is simple and the structure is reasonable. Through the corresponding coordination of various structures, the spring itself elastically drives the slider to press downward, so that the first connecting shaft and the second connecting shaft can be in close contact with the material.

[0014] When the first connecting shaft rotates, the cutting die is driven to rotate, thereby realizing the function of cutting the material, and when the motor rotates, the third connecting shaft is rotated through the pulley and the belt, which is easy to transport the waste after cutting;

[0015] When the polyurethane synthetic leather is transported between the first connecting shaft and the second connecting shaft, the supporting wheels support both sides of the polyurethane synthetic leather to ensure the stability of the polyurethane synthetic leather during transportation, thereby improving the quality during cutting.
