Description

Technical Field

[0001] The utility model relates to the technical field of steel belt cutting devices, and particularly relates to an automatic leather cutting machine. Background Art

[0002] The square pile skirt plate is a component used in the construction field. It is mainly used for sealing between the square pile and the pipe mold during the centrifugal production process of the square pile, and is fixed to both ends of the square pile by pouring concrete. During the production process of the square pile skirt plate, the production of the skirt plate requires cutting a long steel belt into a predetermined length and then bending it into shape.

[0003] Currently, when cutting the steel belt, an encoder is used to control the cutting length of the steel belt, that is, the moving distance of the steel belt is converted into a signal by the rotation of the encoder, and then the cutting length is controlled. However, since the encoder determines the moving distance of the steel belt by the number of turns of its rotation, when the number of turns of its rotation is not an integer number of turns, it cannot sense it. That is to say, the cutting length of the steel belt needs to adapt to the encoder, and its applicability has limitations. In addition, due to its limitations, its cutting accuracy is not high. Summary of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] In order to overcome the deficiencies of the prior art, an automatic leather cutting machine is proposed, which can be applicable to various cutting lengths, has a wide applicability and high precision.

[0006] (2) Technical Solutions

[0007] The utility model is realized through the following technical solutions: The utility model provides an automatic leather cutting machine, which includes a feeding table, and a cutting device capable of cutting the steel belt and a fixed-length measuring device capable of detecting the feeding length of the steel belt are sequentially arranged along the feeding direction of the feeding table. A receiving table for receiving the steel belt is arranged on the fixed-length measuring device. The fixed-length measuring device includes a vertical plate, and an induction device that moves horizontally along a lead screw mechanism is arranged on the vertical plate. The induction device includes a telescopic rod driven by a cylinder to move up and down and a proximity switch. The proximity switch detects the position signal of the telescopic rod and controls the cutting device to cut the steel belt through a controller.

[0008] Furthermore, a guiding device for guiding the steel belt is arranged between the feeding table and the cutting device, and the guiding device includes two symmetrically arranged bearing assemblies.

[0009] Furthermore, the cutting device includes a moving knife seat that moves up and down through an oil cylinder. A pressing plate for limiting the steel belt is arranged on the front side of the moving knife seat, and a fixed knife seat is arranged directly below the pressing plate.

[0010] Further, the receiving table includes a pallet for receiving the steel belt. The pallet can move in the front-rear direction driven by a cylinder, and a linear guide device is arranged directly below the pallet.

[0011] Further, a belt conveyor is arranged directly below the receiving table.

[0012] (III) Beneficial effects

[0013] The utility model has the following beneficial effects compared with the prior art:

[0014] An automatic skin cutting machine mentioned in the utility model uses a servo motor to drive a lead screw mechanism and drive an induction device to move, so that it can freely control the cutting length, and has a wider applicability. The induction device uses the method of steel belt contacting the telescopic rod for induction. Compared with the induction method of encoder rotation, its accuracy is more precise.

Specific implementation manners

[0021] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0022] As Figures 1 - 5An automatic leather cutting machine shown in the figure includes a feeding table 1. Along the feeding direction of the feeding table 1, a cutting device 3 and a fixed-length measuring device 4 are arranged in sequence. A guiding device 6 is arranged between the cutting device 3 and the feeding table 1. The guiding device 6 includes two symmetrically and parallelly arranged bearing assemblies. After the steel belt 2 enters the guiding device 6, it can be limited by the bearings, so that the steel belt 2 keeps a perpendicular position to the tool head when entering the cutting device 3, and the cut will not be skewed during cutting.

[0023] The cutting device 3 includes a moving tool holder 32 that moves up and down through an oil cylinder 31. A pressing plate 33 for limiting the steel belt 2 is arranged on the front side of the moving tool holder 32. A fixed tool holder 34 is arranged directly below the pressing plate 33. When the steel belt 2 is cut, the oil cylinder 31 drives the moving tool holder 32 to move downward and drives the pressing plate 33 to move to press the steel belt 2. Subsequently, the tool head on the moving tool holder 32 cooperates with the fixed tool holder 34 to cut the steel belt 2.

[0024] The fixed-length measuring device 4 includes a vertical plate 41. A lead screw mechanism 42 is arranged on the vertical plate 41. An induction device 43 is arranged on the lead screw mechanism 42 and is driven by a servo motor to move horizontally. The induction device 43 includes a telescopic rod 431 that moves up and down through a cylinder and a proximity switch 432. An induction plate 433 is connected to the end of the telescopic rod 431. A spring is arranged on the telescopic rod 431 to enable reciprocating movement. When the front end of the steel belt 2 touches the telescopic rod 431, the telescopic rod 431 moves backward and drives the induction plate 433 to extend. The proximity switch 432 detects whether the steel belt 2 reaches the predetermined position by detecting whether the induction plate 433 extends, and then sends a signal and controls the cutting device 3 to cut the steel belt 2 through a controller.

[0025] A receiving table 5 for receiving the steel belt 2 is arranged on the fixed-length measuring device 4. The receiving table 5 includes a supporting plate 51 for receiving the steel belt 2. The supporting plate 51 can move in the front-back direction through a cylinder drive. A linear guide device 52 is arranged directly below the supporting plate 51 to make the movement more stable. When the steel belt 2 is cut, the cylinder drives the supporting plate 51 to move backward. At this time, the steel belt 2 loses support and will fall freely. For the convenience of transportation, a belt conveyor 7 is arranged directly below the receiving table 5. The steel belt 2 will fall on the belt conveyor 7 and be transported through it.

[0026] An automatic leather cutting machine mentioned in the present utility model realizes automatic control by using a PLC controller. When it is specifically used, according to the length to be cut, the controller controls the servo motor to drive the lead screw mechanism 42 to drive the sensing device 43 to move to a predetermined position. Subsequently, it controls the cylinder to move downward so that the axis of the telescopic rod 431 of the sensing device 43 is in the same plane as the plane where the steel belt 2 is located. After the adjustment is completed, the long steel belt 2 is manually placed on the feeding table 1 and pushed in the direction of the cutting device 3 through the guiding device 6 and then enters the receiving table 5. When the front end of the steel belt 2 touches the telescopic rod 431, the telescopic rod 431 drives the sensing plate 433 to extend. After the proximity switch 432 detects the sensing plate 433, it sends a signal to the controller and controls the cutting device 3 to cut the steel belt 2. Subsequently, the cylinder drives the supporting plate 51 to move backward, and the cut steel belt 2 loses support and will freely fall onto the belt conveyor 7 directly below the receiving table 5 and is transported away from the automatic leather cutting machine by the conveyor belt.

Without departing from the design concept of the present utility model, various variations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope of the present utility model.
