Description

Technical Field

[0001] The utility model belongs to the technical field of leather punching machines, and in particular relates to a leather punching machine with an automatic waste collection structure. Background Art

[0002] A leather punching machine is a machine specifically designed to create various hole shapes in materials like leather. Its operating principle is primarily based on mechanical pressure or pneumatic impact. Mechanical leather punching machines utilize the rotating radius of a crankshaft to achieve a mechanical reciprocating motion, creating a punching function and punching the desired hole shape in materials like leather. CNC leather punching machines, on the other hand, utilize pneumatic impact as the driving force. Through flexible tool control and independently developed processing software, they can produce a variety of patterns and hole shapes.

[0003] The leather punching machine mainly consists of three parts: the base, the punching head, and the stroke control system. The base supports the entire machine, the punching head is responsible for performing the punching action, and the stroke control system is used to adjust the depth and position of the punching.

[0004] During actual use of the existing leather punching machine, leather waste generated by punching will fall on the surface of the leather, which will affect the punching of the leather. After the use of the leather punching machine, it still needs to be cleaned manually. Utility Model Content

[0005] The purpose of the utility model is to provide a leather punching machine with an automatic waste collection structure, aiming to solve the problem in the prior art that leather waste generated by existing punching will fall on the surface of the leather, which will affect the punching of the leather, and the loss problem that the leather punching machine still needs to be manually cleaned after use.

[0006] To achieve the above-mentioned object, the utility model provides the following technical solution: a leather punching machine with an automatic waste collection structure, comprising a device body, a punching base, a punching rod and a punching head, wherein the punching base is mounted on the surface of the device body, the punching rod is mounted on the output end of the device body, and the punching head is embedded in the bottom end of the punching rod;

[0007] A connecting groove is provided inside the punch rod, and a docking tube is connected to the side surface of the punch rod near the connecting groove. A hose is sleeved on the end of the docking tube, and the other end of the hose is connected to the side surface of the sealed collection box. The side surface of the sealed collection box is connected to a negative pressure tube, and the negative pressure tube is connected to the input end of the negative pressure pump.

[0008] As a preferred embodiment of the utility model of a leather punching machine with an automatic waste collection structure, the punching head, the connecting groove, the butt joint tube, the hose and the sealed collection box constitute a connecting structure.

[0009] As a preferred embodiment of the utility model of a leather punching machine with an automatic waste collection structure, the negative pressure pump forms a negative pressure suction structure through the negative pressure tube and the sealed collection box.

[0010] As a preferred embodiment of the utility model, a leather punching machine with an automatic waste collection structure is provided, the side surfaces of the punching base are respectively provided with horizontal plates, the surface of the side ears of the punching base passing through the horizontal plates is connected with a first guide rod, an electric push rod is installed between the horizontal plate and the side ears of the punching base, a positioning bracket is provided on the upper surface of the horizontal plate, a second guide rod is connected to the upper surface of the horizontal plate passing through the positioning bracket, a spring bar is connected between the second guide rod and the positioning bracket, and the spring bar is sleeved on the surface of the second guide rod.

[0011] As a preferred embodiment of the present invention, a leather punching machine with an automatic waste collection structure comprises a lifting structure formed between the electric push rod and the horizontal plate, and a sliding connection formed between the horizontal plate and the first guide rod.

[0012] As a preferred embodiment of the utility model of a leather punching machine with an automatic waste collection structure, a sliding connection is formed between the positioning bracket and the second guide rod, and an elastic telescopic structure is formed between the positioning bracket and the spring bar.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] According to the utility model, the waste generated by stamping can be stuck inside the punching head. When the negative pressure pump is running, negative pressure can be formed in the sealed collection box through the negative pressure tube. The negative pressure of the sealed collection box can attract the waste through the hose, the docking tube, the connecting groove and the punching head. Under the action of suction, the waste can enter the inside of the connecting groove from the inside of the punching head, and then the waste can be sealed inside the collection box through the docking tube and the hose, thereby realizing the collection of waste and facilitating centralized treatment of waste.

[0015] According to the utility model, after the leather is placed on the upper surface of the punching base, the electric push rod is operated. When the electric push rod contracts, it can drive the cross plate to move downward and drive the positioning bracket to move downward through the spring bar. When the positioning bracket moves downward to the surface of the leather, the cross plate continues to move downward to compress the spring bar and squeeze the positioning bracket through the elastic force of the spring bar, so that the position of the leather can be fixed. In this way, the spring bar can be used to prevent the positioning bracket from directly pressing on the surface of the leather, thereby causing indentations on the surface of the leather.
