Description

Technical Field

[0001] The utility model relates to a leather cutting device, in particular to a projection cutting device with a porous cutting head. Background Art

[0002] The existing leather cutting and punching processes are usually completed in two steps. That is, manually select and lay the leather on the platform surface of the blanking press, and then use the punching head to punch the leather. After punching, the leather is manually unloaded, transferred to the cutting machine, and then the cutting machine is used to cut the leather. This method not only has a low degree of automation of the equipment, high labor intensity of workers, and very low cutting efficiency, but also because of the need to re-position the leather frequently for loading and unloading, it is very easy to cause inaccurate cutting positions and poor cutting quality. Content of the Utility Model

[0003] The purpose of the utility model is to provide a projection cutting device with a porous cutting head, which has the advantages of high degree of automation, high cutting efficiency, high accuracy of cutting, and good cutting quality.

[0004] To achieve the above purpose, the projection cutting device with a porous cutting head provided by the utility model includes a frame, a platform, a driving mechanism, a porous cutting head, a projector, a CCD camera and a control system. The platform is arranged on the frame. The porous cutting head includes a punching head and a cutting head, and both the punching head and the cutting head are arranged at the output end of the driving mechanism. The driving mechanism is arranged on the frame and can drive the porous cutting head to move along the surface of the platform above the platform. The projector and the CCD camera are arranged above the platform and are electrically connected to the control system. The projector can project the cutting trajectory on the surface of the material on the platform, the CCD camera can take pictures of the projected trajectory on the material surface and transmit it to the control system, and the control system can control the movement of the driving mechanism and the porous cutting head according to the trajectory of the CCD camera.

[0005] Compared with the prior art, in the present utility model, a projector and a CCD camera are provided above the platform. The projector can project the graphic trajectory to be cut onto the upper surface of the leather on the platform, and then the CCD camera takes pictures to obtain the information of the graphic trajectory and sends it to the control system. The control system automatically generates a control signal for controlling the driving mechanism. Therefore, the multi-hole cutting tool head can achieve automatic tool feeding and automatically cut the leather, with a high degree of automation. Moreover, since the multi-hole cutting tool head includes a punching head and a cutting head, it can either punch the leather, cut the leather, or perform punching and cutting simultaneously. Therefore, there is no need to transfer the leather to different cutting machines for cutting, saving a lot of time and having a high cutting efficiency; the entire device cuts automatically, with high accuracy and excellent cutting quality.

[0006] Preferably, the projection cutting device with the multi-hole cutting tool head further includes a vacuum adsorption device. The vacuum adsorption device is arranged on the bottom surface of the platform. The platform is provided with a plurality of through holes penetrating the upper and lower surfaces. The output end of the vacuum adsorption device is communicated with the through holes to adsorb and position the material on the surface of the platform. This can fix the material during cutting, prevent it from accidentally shifting, thereby improving the cutting accuracy and reducing the waste rate.

The inner shaft is axially movable and circumferentially fixed and sleeved inside the rotary outer sleeve. The rotary outer sleeve is rotatably disposed on the base body about a central axis. The elastic reset member is disposed between the inner shaft and the rotary outer sleeve. The rotary driving mechanism is disposed on the base body and drives the rotary outer sleeve and the inner shaft to rotate. The lower end of the inner shaft is fixedly connected to the punch head. By rotatably disposing the rotary outer sleeve on the base body and axially movably and circumferentially fixing the inner shaft inside the rotary outer sleeve, therefore, by driving the rotary outer sleeve to rotate through the rotary driving mechanism, the inner shaft and the punch head can be driven to rotate. Also, through the cylinder and the connecting member, the cylinder can drive the inner shaft and the punch head to axially move downward relative to the rotary outer sleeve, so as to achieve the purpose of punching the material. Finally, by disposing the elastic reset member between the rotary outer sleeve and the inner shaft, the inner shaft can axially move upward relative to the rotary outer sleeve to reset. Therefore, the punching head can be used to automatically and continuously punch the material, with high automation degree and high punching efficiency.

[0010] Specifically, the rotary driving mechanism includes a rotary motor, a driving pulley, a driven pulley, and a belt. The rotary motor is disposed on the base body and its output end is connected to the driving pulley. The driven pulley is disposed outside the rotary outer sleeve, and the belt is wound between the driving pulley and the driven pulley.

[0011] Preferably, the number of the punching heads is multiple. The sizes of the punch heads of the punching heads can be different, so that multiple through holes can be punched in the material at the same time, or through holes of different sizes can be punched, greatly improving the punching efficiency.

[0012] Preferably, the cutting head includes a seat body, a vibrator, an angle adjustment mechanism, a rotating outer sleeve, an inner shaft, an elastic reset member, and a cutter. The inner shaft is axially movable and circumferentially fixed and sleeved inside the rotating outer sleeve. The rotating outer sleeve is rotatably arranged on the seat body around a central axis. The elastic reset member is arranged between the inner shaft and the rotating outer sleeve. The angle adjustment mechanism is arranged on the seat body and drives the rotating outer sleeve and the inner shaft to rotate around the central axis by a certain angle. The lower end of the inner shaft is fixedly connected to the cutter, and the vibrator is connected to the upper end of the inner shaft and drives the inner shaft and the cutter to vibrate up and down to cut the material. By rotatably arranging the rotating outer sleeve on the seat body and axially movably and circumferentially fixing the inner shaft inside the rotating outer sleeve, therefore, the angle of the rotating outer sleeve is adjusted by the angle adjustment mechanism, and the inner shaft and the cutter are axially vibrated up and down relative to the rotating outer sleeve by the vibrator, so as to achieve the purpose of wire cutting the material. Finally, by arranging the elastic reset member between the rotating outer sleeve and the inner shaft, the inner shaft moves axially upward relative to the rotating outer sleeve to reset. Therefore, the cutting head can be used to automatically and continuously cut the material, with high automation and high cutting efficiency.

[0013] Specifically, the angle adjustment mechanism includes a servo motor, a driving pulley, a driven pulley, and a belt. The servo motor is arranged on the seat body and its output end is connected to the driving pulley.

Specifically, the vacuum adsorption device 7 includes an air cavity 71 and a vacuum pumping mechanism 72. The air cavity 71 is arranged on the bottom surface of the platform 2 and is communicated with the through holes 21. The output end of the vacuum pumping mechanism 72 is communicated with the air cavity 71. This can fix the leather material 200 during cutting, prevent it from accidentally shifting, thereby improving the accuracy of cutting and reducing the waste rate.

[0024] Again, as Figure 1 and Figure 2As shown, the driving mechanism 3 includes a lateral translation driving mechanism 31, a longitudinal translation driving mechanism 32, and a vertical translation driving mechanism 33. The output end of the lateral translation driving mechanism 31 is connected to the longitudinal translation driving mechanism 32, the output end of the longitudinal translation driving mechanism 32 is connected to the vertical translation driving mechanism 33, and the output end of the vertical translation driving mechanism 33 is connected to the porous cutting tool head 4.

[0025] Please refer to Figure 1 , Figures 4 to 6, the punching head 41 includes a base body 411, a cylinder 412, a connecting member 413, a rotary drive mechanism 414, a rotary outer sleeve 415, an inner shaft 416, an elastic reset member 417, a punch 418, and a gas supply mechanism (not shown in the figure). The cylinder 412 is disposed on the base body 411, and the output end of the gas supply mechanism is connected to the cylinder 412 to drive the output shaft of the cylinder 412 to move. The gas supply mechanism is a gas source and a valve for controlling the entry or discharge of gas into or from the cylinder 412. The cylinder 412 may be an independent cylinder 412. In this embodiment, the cylinder 412 is combined with the base body 411, that is, the base body 411 is used as the cylinder body, a piston is disposed in the cylinder body, and the piston is connected to a telescopic shaft, thereby forming the cylinder 412. The upper end of the output end of the cylinder 412 is connected to the connecting member 413, the connecting member 413 is connected to the upper end of the inner shaft 416, and the inner shaft 416 is axially movable and circumferentially fixed and sleeved inside the rotary outer sleeve 415.

The elastic reset member 417 is disposed between the inner shaft 416 and the rotary outer sleeve 415, and the elastic reset member 417 is a compression spring. The rotary drive mechanism 414 is disposed on the base body 411 and drives the rotary outer sleeve 415 and the inner shaft 416 to rotate. The lower end of the inner shaft 416 is fixedly connected to the punch 418. By rotatably disposing the rotary outer sleeve 415 on the base body 411 and sleeving the inner shaft 416 axially movable and circumferentially fixed inside the rotary outer sleeve 415, therefore, by driving the rotary outer sleeve 415 to rotate through the rotary drive mechanism 414, the inner shaft 416 and the punch 418 can be driven to rotate. Also, through the cylinder 412 and the connecting member 413, the cylinder 412 can drive the inner shaft 416 and the punch 418 to axially move downward relative to the rotary outer sleeve 415, so as to achieve the purpose of punching the leather material 200. Finally, by disposing the elastic reset member 417 between the rotary outer sleeve 415 and the inner shaft 416, the inner shaft 416 axially moves upward relative to the rotary outer sleeve 415 to reset. Therefore, the punching head 41 can be used to automatically and continuously punch the leather material 200, with a high degree of automation and high punching efficiency. Specifically, the rotary drive mechanism 414 includes a rotary motor 414a, a driving pulley 414b, a driven pulley 414c, and a belt 414d. The rotary motor 414a is disposed on the base body 411 and the output end is connected to the driving pulley 414b. The driven pulley 414c is disposed outside the rotary outer sleeve 415, and the belt 414d is wound between the driving pulley 414b and the driven pulley 414c. The number of the punching heads 41 is multiple.The sizes of the punches 418 of the punching head 41 can be different, so that multiple through holes can be punched in the leather material 200 at the same time, or through holes of different sizes can be punched, greatly improving the punching efficiency.

[0026] Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 7 , the cutting head 42 includes a seat body 421, a vibrator 422, an angle adjustment mechanism 423, a cutter 424, a rotating outer sleeve 425, an inner shaft 426 and an elastic reset member 427. The inner shaft 426 is axially movable and circumferentially fixed and sleeved in the rotating outer sleeve 425. The rotating outer sleeve 425 is rotatably arranged on the seat body 421 around the central axis. The elastic reset member 427 is arranged between the inner shaft 426 and the rotating outer sleeve 425, and the elastic reset member 427 is a compression spring. The angle adjustment mechanism is arranged on the seat body 421 and drives the rotating outer sleeve 425 and the inner shaft 426 to rotate around the central axis by a certain angle; the lower end of the inner shaft 426 is fixedly connected to the cutter, and the vibrator is connected to the upper end of the inner shaft 426 and drives the inner shaft 426 and the cutter 424 to vibrate up and down to cut the leather material 200. In this embodiment, the seat body 421 of the cutting head 42 and the seat body 411 of the punching head 41 are integrated. By rotatably arranging the rotating outer sleeve 425 on the seat body 421 and axially movably and circumferentially fixing the inner shaft 426 in the rotating outer sleeve 425, therefore, by driving the rotating outer sleeve 425 to adjust the angle through the angle adjustment mechanism 423, and driving the inner shaft 426 and the cutter 424 to vibrate axially up and down relative to the rotating outer sleeve 425 through the vibrator 422, the purpose of wire cutting the leather material 200 is achieved. Finally, by arranging the elastic reset member 427 between the rotating outer sleeve 425 and the inner shaft 426, the inner shaft 426 moves axially upward relative to the rotating outer sleeve 425 to reset. Therefore, the cutting head 42 can be used to automatically and continuously cut the leather material 200, with high automation and high cutting efficiency. Specifically, the angle adjustment mechanism 423 includes a servo motor 423a, a driving pulley 423b, a driven pulley 423c and a belt 423d. The servo motor 423a is arranged on the seat body 411 and the output end is connected to the driving pulley 423b. The driven pulley 423c is arranged outside the rotating outer sleeve 425, and the belt 423d is wound between the driving pulley 423b and the driven pulley 423c. By setting the angle adjustment mechanism 423, the cutting direction of the cutter 424 can be changed, so as to achieve the purpose of curve cutting and be applicable to cutting various shapes.

[0027] Combining the above and with reference to the accompanying drawings, the working principle of the projection cutting device 100 with a porous cutting head according to the present utility model will be described in detail as follows:

[0028] First, lay a piece of leather 200 on the surface of the platform 2. Then, start the vacuum adsorption device 7. The vacuum adsorption device 7 creates a negative pressure on the surface of the platform 2, thereby adsorbing and positioning the leather on the surface of the platform 2. At this time, the projector 5 projects the light trajectory to be cut from above onto the upper surface of the leather 200. After that, the CCD camera 6 takes a picture of the surface of the leather 200. The CCD camera 6 converts the taken picture into an electrical signal and sends it to the control system. The control system converts the electrical signal into a driving signal to drive the driving mechanism 3 and the porous cutting head 4 to act. Then, the driving mechanism 3 drives the porous cutting head 4 to move to the target position, and the porous cutting head 4 makes corresponding actions according to the driving signal. When punching is required, the punching head 41 works. Specifically, the rotary driving mechanism 414 drives the rotary outer sleeve 415 to rotate, and the rotary outer sleeve 415 drives the inner shaft 416 and the punch 418 to rotate. After that, the cylinder 412 drives the inner shaft 416 to move axially, and the inner shaft 416 drives the punch 418 to move downward, and the punch 418 punches the leather 200. When cutting is required, the vibrator 422 is started and drives the inner shaft 426 and the cutting knife 424 to vibrate, and the cutting knife 424 performs wire cutting on the leather 200. When the cutting trajectory direction changes, the angle adjustment mechanism 423 is started to drive the rotary outer sleeve 425 to rotate a certain angle, thereby driving the inner shaft 426 and the cutting knife to rotate a certain angle. After that, the cutting knife 424 continues to perform wire cutting on the leather 200. When there are multiple punching holes and multiple lines, multiple punching heads 41 and cutting heads 42 can work synchronously at the same time to improve the cutting efficiency.

[0029] Compared with the prior art, in the present utility model, a projector 5 and a CCD camera 6 are arranged above the platform 2. The projector 5 can project the graphic trajectory to be cut onto the upper surface of the leather on the platform 2, and then the CCD camera 6 takes pictures to obtain the information of the graphic trajectory and sends it to the control system. The control system automatically generates a control signal for controlling the driving mechanism 3. Therefore, the porous cutting tool head 4 can achieve automatic tool feeding and automatically cut the leather 200, with a high degree of automation. Moreover, since the porous cutting tool head 4 includes a punching head 41 and a cutting head 42, it can not only punch the leather 200 but also cut it, or perform punching and cutting simultaneously. Therefore, there is no need to transfer the leather 200 to different cutting machines for cutting, saving a large amount of time and having a high cutting efficiency; the entire device automatically cuts with high accuracy and excellent cutting quality.

[0030] The structures and working principles of the projector 5 and the CCD camera 6 involved in the projection cutting device 100 with a porous cutting tool head of the present utility model are well-known to those of ordinary skill in the art and will not be described in detail herein.

[0031] The above-disclosed are only the preferred examples of the present utility model, and of course, the scope of the rights of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present utility model still fall within the scope covered by the present utility model.
