[0021] The present invention is further described and illustrated below in conjunction with specific embodiments and accompanying drawings:

[0022] Please refer to Figure 1-Figure 3 .

[0023] The utility model discloses a device for grinding the edge of a material plate, which comprises a machine platform 1, a limit cylinder 2 and an adjustment mechanism 4.

[0024] A frame 12 is provided on the top of the machine 1, and the limit cylinder 2 is fixedly connected to the frame 12, and the limit cylinder 2 is suspended above the top of the machine 1; a pressing plate 21 is rotatably connected to the output shaft of the limit cylinder 2, and the connection between the output shaft of the limit cylinder 2 and the pressing plate 21 is located at the center of the top of the pressing plate 21, and the output shaft of the limit cylinder 2 pushes the pressing plate 21 close to the top of the machine 1; in this embodiment, the length and width of the pressing plate 21 are preferably smaller than the length and width of the material tray 6 to prevent the sandpaper 443 from hitting the pressing plate 21 when grinding the edge of the material tray 6; a pressure sensor is provided on the pressing plate;

[0025] The machine 1 is provided with a rotating mechanism 3, which includes a rotating motor 31 and a turntable 32; the rotating motor 31 is placed inside the machine 1, the rotating motor 31 is fixedly connected to the inner wall of the machine 1, the output shaft of the rotating motor 31 passes through the top of the machine 1, the center of the bottom of the turntable 32 is fixedly connected to the output shaft of the rotating motor 31, the rotating mechanism 3 is provided with a processing area, the processing area is located at the top of the turntable 32, a plurality of material trays 6 are stacked in the processing area, and the stacked material trays 6 at the bottom are placed on the top of the turntable 32;

[0026] The pressing plate 21 is located above the processing area, and the output shaft of the limiting cylinder 2 pushes the pressing plate 21 to touch the material tray 6 stacked on the top, so that multiple material trays 6 are clamped between the bottom of the pressing plate 21 and the top of the turntable 32, thereby limiting the multiple material trays 6 in the processing area; the material trays stacked on the top are in contact with the pressure sensor, and the pressure sensor monitors the downward pressure of the pressing plate. When the downward pressure of the pressing plate is insufficient, the equipment stops running to avoid the pressing plate being unable to firmly limit the material tray, which causes the material tray to be pushed out of the working area by the grinding component; when the output shaft of the rotating motor 31 drives the turntable 32 to rotate, the turntable 32 also drives the material tray 6 to rotate synchronously. The design of the output shaft of the limiting cylinder 2 and the pressing plate 21 being rotatably connected can make the pressing plate 21 rotate synchronously when the material tray 6 rotates, thereby avoiding friction between the stacked material tray 6 on the top and the bottom of the pressing plate 21.

[0027] The adjusting mechanism 4 is connected to the frame 12, and two symmetrical slides 41 are slidably connected to the adjusting mechanism 4. The adjusting mechanism 4 includes two adjusting brackets 42, a double-threaded screw rod 421 and an adjusting motor 43; the adjusting bracket 42 is fixedly connected to the frame 12, and the two adjusting brackets 42 are respectively close to the two ends of the frame 12, and the slide 41 is located between the two adjusting brackets 42; in this embodiment, the two sections of threads on the double-threaded screw rod 421 are respectively a forward thread and a reverse thread, and the two ends of the double-threaded screw rod 421 are respectively rotatably connected to the two adjusting brackets 42, and the double-threaded screw rod 421 is located above the processing area;

[0028] Furthermore, two light rods 422 are fixedly connected between the two adjustment brackets 42. The two light rods 422 are respectively located on both sides of the double-threaded screw 421, and the light rods 422 and the double-threaded screw 421 are parallel to each other; the two slide seats 41 are respectively slidably connected to the two sections of the threads of the double-threaded screw 421, and the slide seat 41 is slidably connected to the light rods 422. The light rods 422 can make the slide seat 41 slide on the double-threaded screw 421 more stably;

[0029] Furthermore, the adjusting motor 43 is fixedly connected to one of the adjusting brackets 42, and the output shaft of the adjusting motor 43 and one end of the double-threaded screw 421 are fixedly connected with pulleys, and the outer sides of the two pulleys are provided with transmission belts 431; the output shaft of the adjusting motor 43 drives the double-threaded screw 421 to rotate through the transmission belt 431; the double-threaded screw 421 is driven to rotate forward or reversely by the output shaft of the adjusting motor 43, so that the double-threaded screw 421 drives the two slides 41 to slide closer to each other or slide away from each other.

[0030] A grinding assembly 44 is provided on the slide 41, and the grinding assembly 44 includes a grinding cylinder 441 and a slide plate 442; in this embodiment, two grinding cylinders 441 are preferably provided, and the grinding cylinders 441 are fixedly connected to the slide 41, the two grinding cylinders 441 are opposite to each other, and the output shafts of the two grinding cylinders 441 are close to each other, and the output shafts of the two grinding cylinders 441 are parallel to each other; a notch is provided on the slide 41, and the output shaft of the grinding cylinder 441 is close to the notch;

[0031] Furthermore, the slide plate 442 is slidably connected to the slide seat 41, the two slide plates 442 are parallel to each other, a connecting block extends from the slide plate 442, the connecting block is located in the notch, and the output shafts of the two polishing cylinders 441 are fixedly connected to the two sides of the connecting block respectively;

[0032] Furthermore, the skateboard 442 is provided with sandpaper 443. In this embodiment, the sandpaper 443 is preferably multiple pieces, and the multiple pieces of sandpaper 443 are arranged at intervals and pasted on the skateboard 442. The design of pasting the sandpaper 443 on the skateboard 442 can be used to tear off the sandpaper 443 and paste new sandpaper 443 when the grinding efficiency of a single piece of sandpaper 443 becomes low. This facilitates maintenance while allowing the device to maintain a high grinding efficiency. The sandpaper 443 of the two skateboards 442 are respectively close to the two ends of the processing area.

[0033] After the pressing plate 21 touches the material tray 6 stacked on the top, the output shaft of the adjusting motor 43 drives the double-threaded screw 421 to rotate forward, and the double-threaded screw 421 drives the two slide seats 41 to slide close to each other. When the slide seat 41 slides, the two grinding cylinders 441 located on the slide seat 41 are started, and when the output shaft of one of the grinding cylinders 441 extends, the output shaft of the other grinding cylinder 441 contracts, and when the output shaft of one of the grinding cylinders 441 contracts, the output shaft of the other grinding cylinder 441 extends, and the output shaft of the grinding cylinder 441 repeatedly extends and contracts, driving the slide plate 442 to slide back and forth on the slide seat 41, so that the sandpaper 443 on the slide plate 442 wipes off the scraps of the material tray 6 when it contacts them;

[0034] After completing the grinding of two parallel sides of the material disc 6, the output shaft of the adjustment motor 43 drives the double-threaded screw 421 to reverse, and the double-threaded screw 421 drives the two slide seats 41 to slide away from each other, and the rotating motor 31 drives the turntable 32 to rotate 90°, so that the other two parallel sides of the material disc 6 are respectively facing the sandpaper 443 of the two slides 442, and then the grinding work of the other two sides of the material disc 6 is started.

[0035] Please refer to Figure 1 , Figure 4 and Figure 5 .

[0036] Air gun nozzles 5 are provided on both sides of the slide 41. The air gun nozzles 5 on the two slides 41 are opposite to each other. Four slide slots 111 are provided on the top of the machine 1. The slide slots 111 penetrate into the machine 1. The air gun nozzles 5 are connected with air guide pipes 51. The machine 1 is provided with an air storage device 121. The air guide pipes 51 pass through adjacent slide slots 111 and are connected with the air storage device 121. The air storage device 121 provides compressed gas to the air gun nozzles 5 through the air guide pipes 51.

[0037] When the grinding assembly 44 is grinding the material tray 6, the gas storage device 121 is started to provide compressed gas to the air gun nozzle 5, forming a wind wall between the two opposite air gun nozzles 5, and the debris generated when grinding the scraps of the material tray 6 is confined between the two slides 41 and the two wind walls, avoiding the debris from affecting the health of the workers; when the slide 41 slides, the air duct slides in the slide groove 111, and the slide groove 111 leaves moving space for the air duct 51 to slide with the slide 41.

[0038] Two dust collection grooves 112 are provided on the top of the machine 1, and the two dust collection grooves 112 are respectively close to the two ends of the processing area, and the dust collection grooves 112 penetrate into the machine 1; a fan 13 is provided in the machine 1, and a dust collection pipe 131 and a connecting pipe 132 are provided in the machine 1, one end cover of the dust collection pipe 131 is arranged on one of the dust collection grooves 112, one end cover of the connecting pipe 132 is arranged on the other dust collection groove 112, the other end of the connecting pipe 132 is connected to the middle part of the connecting pipe 132, and the other end of the connecting pipe 132 is connected to the air inlet of the fan 13;

[0039] The fan 13 draws air into the dust collection duct 131 and the connecting duct 132, so that the debris between the two slide seats 41 and the two wind walls can be sucked into the two dust collection grooves 112, and the debris is then sucked into the fan 13 through the dust collection duct 131 and the connecting duct 132, thereby collecting the debris.

[0040] Two gratings are provided on one side of the frame 12. The two gratings are respectively close to the two slides 41 and are opposite to each other. When the worker places the material tray 6 into the processing area, the worker's arm will block the light emitted by the gratings, and the equipment stops running. When the worker places the material tray 6 and withdraws his arm from the processing area, the light emitted by the gratings is not blocked, and the equipment starts running, thereby improving the equipment's ability to ensure safe production.

[0041] The utility model provides a device for grinding the edge of a material tray. A worker stacks a plurality of material trays in a processing area on a rotating mechanism. The rotating mechanism rotates a certain angle to direct the two edges on both sides of the material tray toward the sandpapers on the two slides respectively. The output shaft of the limiting cylinder pushes a pressure plate to approach and touch the material tray stacked on the top, so that the pressure plate limits the plurality of material trays in the processing area. The adjusting mechanism drives the two slide seats to slide close to each other. During the sliding process of the slide seats, the output shaft of the grinding cylinder extends and then contracts and repeatedly runs, driving the slide plate to slide back and forth on the slide seat, so that the sandpaper on the slide plate contacts the scraps of the material tray and wipes them off. When the two edges of the material tray are polished, the adjusting mechanism drives the two slide seats to slide away from each other, and the rotating mechanism drives the material tray to rotate 90 degrees, directing the other two edges of the material tray toward the sandpapers on the two slides respectively, and grinding the other two edges of the material tray. The equipment can grind a plurality of material trays at one time, thereby improving the efficiency of removing the scraps of the material trays.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
