Description

Technical Field

[0001] The utility model relates to the technical field of blanking and cutting equipment, in particular to an easily adjustable cutting device applied to a blanking machine. Background Art

[0002] The blanking machine is a kind of equipment used in leather punching technology. It is a machine that uses the force of machine movement to pressurize the knife die to cut the material. The blanking machine is an indispensable equipment in some light industries. In some production lines, the blanking machine can greatly increase production efficiency, so it has been widely used.

[0003] Although the blanking machine in traditional technology has the cutting function, it is inconvenient to adjust the cutting length of the material. Multiple cutting and manual measurement are required to adjust the cutting length. In addition, due to the temporary lack of conveying power during cutting, effective transmission cannot be achieved, thus affecting the continuous processing. For this reason, we propose an easily adjustable cutting device for the blanking machine. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an easily adjustable cutting device applied to a blanking machine. The device has a reliable cutting control unit. By multiplying the time of the cutting stroke with the speed of material transmission, the length value of the cut material can be obtained. The time, speed, cutting length and other parameters can be displayed in real time through the display screen on the upper end of the control panel, and the transmission speed of the belt conveyor can be adjusted through the control panel, so as to simply and effectively realize the regulation of the cutting length of the material; the device also has a reliable cutting and discharging unit, which can effectively complete the downward pressing and punching operation, and can push the cut material to the belt conveyor on the right after the punching is completed, so that the material block can continue to be transported to the right, thereby facilitating the continuous cutting process; by opening an exhaust hole, the airflow during punching can be discharged downward to prevent the airflow from flowing back upward and causing the material to be blown up, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an easily adjustable cutting device applied to a blanking machine, comprising a main frame, a cutting adjustment unit and a cutting discharge unit;

[0006] Main frame: It is arranged horizontally and has a U-shaped structure on the side. An inverted U-shaped auxiliary mounting frame is fixedly connected to the middle of the upper end of the main frame;

[0007] Cutting control unit: including a belt conveyor, a side baffle, a cutting bracket, a linear speed sensor, an induction timer, a control console and an emergency stop button. A U-shaped cutting bracket is fixedly connected to the middle position inside the main frame, and the cutting bracket is arranged longitudinally. A belt conveyor is installed at both ends of the main frame. The belt conveyor is arranged transversely and side baffles are installed on both the front and rear sides. A linear speed sensor is embedded and installed at the end face of the belt conveyor on the left. The cutting and discharging unit includes a tool mounting frame, and an induction timer is embedded and installed on the left side of the tool mounting frame. The linear speed sensor and the induction timer are electrically connected to the control console installed at the front end of the main frame. An emergency stop button is installed on the right side of the control console, and a display screen is embedded and installed at the oblique front end.

[0008] Cutting and discharging unit: installed on the upper and lower sides of the auxiliary mounting frame.

[0009] The materials are put into the belt conveyor on the left side of the device and transported to the right. The side baffle can prevent the materials from falling during transportation. When the materials move to the cutting bracket in the middle of the device, the cutting and discharging unit controls the tool to perform the shearing operation downward. The U-shaped cutting bracket can provide enough space for the tool to move downward. At the belt conveyor on the left, the linear speed sensor is used to detect the speed of material transmission, and the induction timer is used to detect the time taken by the tool for one shearing stroke. By multiplying the shearing stroke time with the material transmission speed, the length value of the sheared material can be obtained. The display screen at the top of the control panel can display parameters such as time, speed and shearing length in real time, and the transmission speed of the belt conveyor can be adjusted through the control panel, so as to simply and effectively realize the regulation of the shearing length of the materials. Pressing the emergency stop button on the right side of the control panel can perform emergency braking on the entire device.

[0010] Furthermore, the cutting and discharging unit comprises a hydraulic cylinder, a tool mounting frame, a shearing knife and a buffer pad. A hydraulic cylinder is installed at the middle position of the upper end of the auxiliary mounting frame, and a fixed frame is installed on the left and right sides of the hydraulic cylinder. A vertical slide groove is provided on the side of the auxiliary mounting frame, and a buffer pad is fixedly installed on the lower side of the vertical slide groove and near the inner corner. The tool mounting frame is arranged longitudinally and the two ends are slidably connected in the front and rear two vertical slide grooves. The telescopic end of the hydraulic cylinder is arranged downward and fixedly connected to the middle part of the upper end of the tool mounting frame, and the shearing knife is fixedly installed at the lower end of the tool mounting frame. The hydraulic cylinder is used to drive the tool mounting frame to move vertically, and the tool mounting frame is used to install and fix the shearing knife. The shearing knife is driven by the hydraulic cylinder to punch downward quickly to cut the material above the cutting bracket. The buffer pad can buffer the tool mounting frame after the shearing knife completes the cutting to reduce the impact of the tool mounting frame and then return to its original position upward.

[0011] Furthermore, the cutting and discharging unit also includes an auxiliary telescopic rod and an exhaust hole. Two auxiliary telescopic rods are fixedly connected between the tool mounting frame and the top of the auxiliary mounting frame. The two auxiliary telescopic rods are symmetrically distributed on the front and rear sides of the hydraulic cylinder telescopic rod.

The auxiliary telescopic rod is used to connect the two ends of the tool mounting frame with the top of the auxiliary mounting frame, so as to cooperate with the clamping and limiting effect of the side slide groove of the auxiliary mounting frame to improve the stability of the tool mounting frame when it is lifted and slid. When the tool mounting frame and the shearing knife punch downward, they will drive the airflow. The exhaust hole allows the airflow to be discharged downward, thereby preventing the airflow from flowing back upward and causing the material to be blown up.

[0012] Furthermore, the cutting and discharging unit also includes an electric push rod and a push plate. A square installation slot is provided at the middle position on the right side of the tool mounting frame. An electric push rod is embedded and installed inside the installation slot. The telescopic end of the electric push rod extends to the right, and a push plate is fixedly connected to the end. The push plate can be stored in the installation slot. When the shearing knife completes the punching, the electric push rod will push the push plate outward from the installation slot, thereby pushing the cut material to the belt conveyor on the right side, so that the material block can continue to be transported to the right, thereby facilitating the continuous cutting process. When the shearing knife is reset upward, the push plate synchronously returns to the installation slot on the right side of the tool mounting frame.

[0013] Furthermore, it also includes support columns and footrests. The four corners of the lower end of the main frame are fixedly connected with vertical support columns, and the lower end of each support column is fixedly connected with a footrest. The support columns are used to support the entire device, and the footrests increase the contact area with the ground, thereby improving the stability of the device when placed.

[0014] Furthermore, it also includes a support rod and a supporting block, wherein oblique support rods are fixedly connected between the left and right sides of the main frame and each belt conveyor, the lower ends of the front and rear side baffles of the belt conveyor are clamped and fixedly connected inside the U-shaped supporting block, and the oblique upper end of the support rod is fixedly connected to the lower side of the supporting block.
