[0002] Melamine tableware, also known as imitation porcelain tableware, is formed by heating and pressurizing melamine resin powder. Melamine tableware is used in the catering industry and children's catering industry for its lightness, beauty, low temperature resistance, and non-fragile properties. When processing melamine tableware, a hole guide device is required to complete the punching operation of melamine tableware. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a melamine bowl manual punching and grinding machine with a publication number of CN209774281U, including a grinding device, a grinding assembly, a grinding motor, a grinding block, a connecting block, a clamping plate, a limit clamping block, a push spring, an avoidance notch, a convex ridge, a mounting block, a partition groove, a groove, a screw slide, a dust removal device, a grille, a dust collection box, an air suction duct, an exhaust fan, a collection box, a lap device, a lap assembly, a screw, an adjusting nut, a lap part, an extension plate, a first lap block, a second lap block, a limit hole, Limit button, hand support plate, cabinet, cabinet door, guide plate, waste box, handle, shell and blocking plate. When in use, the area to be polished is rubbed with the polishing block by holding the melamine bowl in hand. The screw slide can adjust the position of the polishing block according to the user's body shape by making the slide vertically move, so as to be suitable for different people. The area to be polished of the melamine bowl is touched with the polishing block, and the polishing block polishes the area to be polished of the dishware bowl. When it is necessary to punch a hole in the melamine bowl, the polishing block is conical in shape. The drilling operation is performed by bringing the position to be drilled into contact with the sharp end of the bottom of the grinding block. The annular partition groove set at the lower section of the grinding block can prevent the hole from being too large. Since the melamine bowl is light in texture, long-term lifting and grinding will not cause damage to the user's hands. When the waste after grinding and drilling the melamine bowl enters the dust box through the grille, the exhaust fan works to absorb the waste in the dust box into the suction channel. Since the suction duct is L-shaped, when the waste enters the suction duct, the exhaust fan works at intervals to make the waste fall into the aggregate The box and the collection box are used to collect waste. The grille can allow larger waste to pass through and the grille can also prevent the melamine bowl from falling into the dust box. When defective melamine bowls appear during polishing, the hinged cabinet door is pushed to allow the defective products to pass through the cabinet door into the cabinet and be suspended directly above the guide plate. The defective products fall onto the guide plate, and the guide plate transports the defective products into the waste box. After the waste box has been used for a period of time, the waste box is pulled out of the cabinet through the handle. After the defective products in the waste box are cleared, the waste box is pushed back into the cabinet.

[0004] In the above utility model, when the induced air fan is working, the waste can be drawn into the dust box through the fence, and then enter the collection box along the suction channel. When the collection box is full of waste, the dust suction work needs to be stopped before the waste inside the collection box can be cleaned. The termination of the dust suction work requires the stopping of the drilling work to prevent the waste from floating in the working space. This operation will affect the working efficiency of this utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
