[0017] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model:

[0018] like Figures 1 to 3 The automatic punching and cutting equipment of a material tray shown in the figure includes a discharge cabinet 1, a discharge mechanism, a positioning and moving mechanism, a clamping and positioning mechanism and a punching and cutting material collecting mechanism. The discharge mechanism is located inside the discharge cabinet and is used for automatic material collection and discharge of the material strip. The positioning and moving mechanism is installed on the rear side of the discharge cabinet and is used to receive the material strip discharged by the discharge mechanism and to position and pull it. The clamping and positioning mechanism is located on the rear side of the positioning and moving mechanism and is used for clamping and positioning the material strip after traction. The punching and cutting material collecting mechanism is located on the rear side of the clamping and positioning mechanism and is used for punching and cutting the material strip after clamping and collecting finished materials and waste materials. A control system for controlling the discharge mechanism, the positioning and moving mechanism, the clamping and positioning mechanism and the punching and cutting material collecting mechanism is provided on the lower side of the clamping and positioning mechanism and the punching and cutting material collecting mechanism. In actual application, an external touch screen 2 and a start button 3 connected to the control system can be provided, so as to conveniently set the punching and cutting parameters and start and stop equipment.

[0019] In this embodiment, in order to further facilitate the discharge and collection of materials, the discharge mechanism includes a cross bar 4, an inclined bar 5, a discharge tray 6, a collection tray 7 and a product detection mechanism 8. The cross bar is horizontally arranged and one end of the cross bar is connected to the middle position of the upright frame bar on one side of the discharge mechanism. The inclined bar is obliquely arranged in the discharge cabinet and its lower end is connected to the bottom frame bar on one side of the discharge cabinet and is located below the cross bar, and the other end is connected to the rotating shaft end of the discharge tray. The discharge tray is fixed on the rotating shaft and driven to rotate by a stepper motor. The other end of the cross bar is connected to the middle position of the inclined bar. The collection tray is fixed to the inclined bar below the cross bar through a connecting piece. The product detection mechanism is fixed on the cross bar and is used to detect and position the material belt discharged from the discharge tray. However, in actual application, the material belt is wound on the discharge tray, and the material belt membrane will be wound on the discharge tray together with it. Therefore, when the material is initially discharged, the material belt body will first be pulled under the roller on the product detection mechanism and enter the rear positioning and moving mechanism, while the material belt membrane released together with the material belt body will be pulled down to the collecting tray and collected by the collecting tray. The sensor on the product detection mechanism will detect the material belt body and transmit the detection signal to the control system. The control system sends a command to the stepper motor to control the discharge tray to rotate a certain angle, thereby realizing the rotary discharge process. The collecting tray will also follow the rotation to realize the rotary collection of the material belt membrane once, thereby realizing the synchronous discharge and collection of the material belt body and the material belt membrane. Furthermore, in order to improve the transmission stability of the material belt diaphragm, a material belt clamping rod 9 is provided at the lower end of the inclined rod, one end of which is connected to the inclined rod and is located below the collecting tray, and the other end is provided with a roller around which the material belt diaphragm is supplied. Therefore, after the material belt diaphragm flows out from the discharge tray, it first passes through the lower part of the roller at the end of the clamping rod and continues to be wound around the discharge tray, thereby improving the stability and uniformity of the material belt diaphragm during transmission from the discharge tray to the collecting tray.

[0020] In this embodiment, in order to further facilitate the feeding of the material belt, a support frame 10 is provided on the rear side of the unloading cabinet, and a fixed seat plate 11 is provided on the top of the support frame. The positioning and moving mechanism and the positioning and clamping mechanism are both installed on the fixed seat plate. The positioning and moving mechanism includes a base 12, a moving cylinder 13, a material belt transmission platform 14, a front positioning cylinder 15, a supporting cross plate 16, and a front positioning pin 17. The base is fixed on the fixed seat plate, and the material belt transmission platform is horizontally supported above the base by a supporting assembly. The moving cylinder is located between the material belt transmission platform and the base, and the piston moving part of the moving cylinder moves horizontally back and forth. The supporting cross plate is located above the material belt transmission platform and one end of which is connected to the piston moving part of the moving cylinder through a connecting plate. The front positioning cylinder is fixed on the supporting cross plate, and its piston rod end passes through the supporting cross bar and is arranged downward. The piston The lower end of the rod is connected to a positioning cross plate 18, and there are two front positioning pins that are respectively connected to the two ends of the positioning cross plate and are arranged vertically downward. A transmission groove arranged in the front and rear directions is provided in the middle of the material belt transmission platform and is used for the forward and backward movement transmission of the material belt. The positioning pins correspond to the positioning holes on both sides of the material belt up and down. Therefore, in actual application, the front positioning cylinder drives the front positioning pin to descend and insert it into the positioning holes on both sides of the material belt, and then starts the moving cylinder to drive the front positioning cylinder and the pin to move backward, and then drives the material belt to move on the material belt transmission platform to realize the feeding process of the material belt. After the feeding is completed, the front positioning cylinder and the moving cylinder return to the initial position, and in order to facilitate the material belt to enter the belt positioning moving mechanism, a corresponding discharge opening is opened on the cabinet panel on the rear side of the discharge cabinet, so as to facilitate the material belt to enter the rear positioning moving mechanism from the cabinet.

[0021] In this embodiment, in order to facilitate the positioning and pressing of the material belt, the positioning and pressing mechanism includes a door-type support frame 19, a rear positioning cylinder 20, and a rear positioning pin 21. The door-type support frame spans across both sides of the material belt conveyor and is located on a base on the rear side of the positioning and moving mechanism. The rear positioning cylinder is fixed on the transverse frame of the door-type support frame and its piston rod end passes through the transverse frame and is vertically arranged downward. The lower end of the piston rod of the rear positioning cylinder is connected to a rear positioning transverse plate 22. There are two rear positioning pins, which are respectively vertically connected to the two ends of the rear positioning transverse plate. The rear positioning pins correspond to the positioning holes on both sides of the material belt up and down. A pressure head 23 for pressing the material belt is provided on the lower middle side of the rear positioning transverse plate. Therefore, when the positioning and moving mechanism positions and moves the material belt, the rear positioning cylinder drives the rear positioning pin and the pressure head to descend, and the rear positioning pin is inserted into the positioning hole of the material belt. The pressure head is pressed in the middle of the material belt, and then the material belt is pressed and positioned, thereby improving the stability of the rear punching device when punching the material belt.

[0022] Furthermore, to facilitate the punching of the material strip, the punching and collecting mechanism includes a punching device 24, a waste collection box 25 and a finished product collection box 26. The punching device is located on a base on the rear side of the positioning and pressing mechanism and is used for punching and pressing the material strip. The finished product collection box is located in the middle and lower side of the device and is used for collecting the finished products after punching. The waste collection box is located below the base, and a blanking port connected to the waste port of the punching device is provided on the base. The waste collection box is located below the blanking port. The punching device can be equipped with ordinary punching equipment on the market, including a punching cylinder, an upper die, a blanking die and other structures to meet the punching process. After the material strip is fed to the punching position of the punching device, the punching cylinder drives the punching upper die to apply pressure downward, punches the product into the blanking die and then falls into the finished product collection box, and then the waste is blown out from the product waste outlet to the blanking port by an external blowing device, and then enters the waste collection box at the bottom from the blanking port. Furthermore, a support platform 27 for transmitting and supporting the material strip is provided between the positioning and clamping mechanism and the punching device, and the lower end of the support platform is fixed to one side of the base of the punching device, thereby facilitating the stable transmission process of the material strip.

[0023] In the actual punching process, at the beginning, the material belt body and the material belt diaphragm on the discharge tray are led out respectively, and the material belt body is led out to the mobile positioning mechanism and the positioning and pressing mechanism until it enters the feed port of the punching device. The material belt diaphragm is pulled and wrapped on the collecting tray, and then the punching number is manually set in the touch screen connected to the control system, and the start button is pressed. After the front positioning cylinder descends to position the product, the mobile cylinder moves forward and drives the material belt to enter the punching position of the punching device. The rear positioning cylinder positions and presses the product downward, and then the front positioning cylinder rises, and the mobile cylinder moves backward to the initial position to complete a product movement. After the product enters the punching position, the punching device punches it. When the above-mentioned mobile cylinder moves forward to drive the material belt to move forward to feed, after the detection sensor above the product detection mechanism detects the product, the stepper motor that drives the discharge tray to rotate drives the material tray to rotate and discharge the material, and the drive motor of the collecting tray will also drive the collecting tray turntable to rotate and collect the material belt diaphragm. After entering the punching device for punching and cutting, the finished product enters the finished product receiving box, and the waste will fall into the waste collection box below. The above process is repeated in sequence until the manually set number of times is reached and then stops. After the finished product collection box is manually taken out, the entire automatic punching process of this equipment is completed.

[0024] It should be emphasized that the above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
