Description

Technical Field

[0001] This utility model relates to the technical field of knife sharpening devices, specifically a sand column type knife sharpening device with knife width detection function. Background Technology

[0002] Automatic cutting machines are used for cutting and slitting sheet materials in various industries. They do not require any molds; they are controlled by system software and directly cut the products. Simply set the relevant parameters on the operating platform, and the computer transmits the corresponding instructions to the cutting machine. The cutting machine then quickly cuts according to the received design drawings. With a high degree of automation and simple operation, it is currently the cutting equipment used in many industries.

[0003] The sharpening device is an important component of automatic cutting machines, used to sharpen the cutting blades and keep them sharp. It sharpens the blades by moving a grinding column. However, in existing designs, a rotating platform is designed at the bottom of the base plate to allow the equipment to rotate. Figure 1 As shown, the grinding column is controlled by a cylinder to feed and reset the slider on the guide rail, thus adjusting the movement of the grinding column. Because the installation space on the base plate is small, small cylinders have insufficient extension and retraction strokes, while large cylinders interfere with the rotating platform. Existing solutions lack tool width detection functionality. Therefore, to satisfy the movement of the guide rail and grinding column, avoid cylinder interference, and simultaneously implement tool width detection, a grinding column-type tool sharpening device with tool width detection function was designed.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 2 and 3This utility model provides a technical solution: a sand column type grinding device with blade width detection function, including a base plate 1, a guide rail 3 and a guide block 31 fixed at the upper end of the base plate 1, the guide block 31 sliding on the guide rail 3, a grinding adjustment bracket 5 for connecting a sand column 4 connected to the lower end of the guide block 31, a wire bracket 9 fixed to the side of the grinding adjustment bracket 5, a reset mechanism provided on one side of the wire bracket 9, the reset mechanism is used to control the reset of the guide block 31 and the wire bracket 9, the reset mechanism is fixed at the lower end of the base plate 1, a fixed seat 91 is connected to the wire bracket 9, the fixed seat 91 is fixed to the other end of the wire bracket 9, a feeding mechanism is installed on the base plate 1, a wire roller 13 is connected to the lower end of the base plate 1 through a bearing seat 12, a wire roller 103 is wound on the wire roller 13, and the feeding mechanism and the fixed seat 91 are connected by the wire 103. 03 connects and controls the feed of the wire support 9 and guide block 31. The wire roller 13 changes the direction of movement of the wire 103, extending one end of the wire 103 above the base plate 1, making the wire 103 vertically distributed. This further increases the installation space by installing the feeding mechanism above the base plate 1, facilitating the selection of equipment on the feeding mechanism and avoiding interference between the feeding mechanism installed at the lower end of the base plate 1 and other equipment such as the rotating platform. The feeding mechanism controls the feed of the wire support 9, guide block 31, and grinding adjustment bracket 5, causing the abrasive column 4 on the grinding adjustment bracket 5 to move along the guide rail 3, moving the abrasive column 4 to the cutting edge of the cutting blade 2 to grind the blade, improving the symmetry and sharpness of the blade. After grinding, the reset mechanism moves the wire support 9 and guide block 31 to the initial position, realizing the reset of the abrasive column 4.

[0015] The reset mechanism includes a pin mounting block 14 fixed to the lower end of the base plate 1 and a spring 15 connected to the pin mounting block 14. A pin 92 is formed on the other side of the wire bracket 9. The spring 15 is connected between the pin mounting block 14 and the pin 92. By moving the wire bracket 9, the spring 15 is stretched. When the cutting blade 2 finishes sharpening, the cylinder no longer maintains air pressure. Thus, under the elastic force of the spring 15, a resetting force is applied to the wire bracket 9, which stretches the wire 103 and further drives the end of the cylinder 101 to extend. The wire bracket 9 also drives the sharpening adjustment bracket 5 and the guide block 31 to reset.

[0016] The feeding mechanism includes a vertical cylinder 101 fixed above the base plate 1. A steel wire 103 is connected to the telescopic end of the cylinder 101. A cylinder bracket 10 is fixed to the upper end of the base plate 1, and the cylinder 101 is fixed to the upper end of the cylinder bracket 10. The steel wire 103 is fixed to the telescopic end of the cylinder 101 through a steel wire connecting pipe 102. The steel wire 103 is connected to the fixed seat 91 through a steel wire roller 13. The fixed seat 91 and the pin 92 are respectively connected to the two ends of the steel wire bracket 9. The steel wire roller 13 is used to change the direction of movement of the steel wire 103, so that one end of the steel wire 103 extends above the base plate 1, making the steel wire 103 vertically distributed. The cylinder 101 is further installed above the base plate 1 through the cylinder bracket 10, which increases the installation space of the cylinder 101, facilitates the selection of the cylinder 101, and avoids interference between the cylinder installed at the lower end of the base plate 1 and other equipment such as the rotating platform.

[0017] A guide seat 11 is also fixed on the lower surface of the base plate 1. The guide seat 11 is located between the wire roller 13 and the fixed seat 91. The guide seat 11 guides the movement of the wire 103 so that the movement direction of the wire 103 is parallel to the movement direction of the guide block 31.

[0018] A sensor 32 is connected to the sharpening adjustment bracket 5. A positioning block 16 is formed on one side of the base plate 1. The positioning block 16 protrudes outward and is located on one side of the guide block 31. The positioning block 16 is set opposite to the sensor 32. The sensor 32 is used to detect the distance between the sensor 32 and the positioning block 16 and collect the change in blade width each time the blade is sharpened. The cutting program will automatically compensate according to the change in blade width value to ensure cutting accuracy and quality. At the same time, when the blade width is close to the scrap value, a warning prompt will pop up to remind the user to replace the blade.

[0019] A sand column bracket 8 is fixed to the lower side of the grinding tool adjustment bracket 5. A sand column 4 is rotatably connected to the side of the sand column bracket 8. A motor mounting plate 6 is also fixed to the side of the grinding tool adjustment bracket 5. A motor 7 is fixed on the motor mounting plate 6. The motor 7 and the sand column 4 are driven by a belt.

[0020] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
