Description

Technical Field

[0001] The utility model relates to an edge grinding machine, in particular to an edge grinding machine for plastic tableware, belonging to the technical field of tableware production. Background Technique

[0002] With the rapid development of the catering industry, the demand for plastic tableware has also increased, which has led to the rapid rise of the plastic tableware industry. Plastic tableware is formed by heating and pressing melamine resin powder. Due to its light weight, beauty, low temperature resistance, boiling resistance, and unbreakability, it is widely used in the catering industry. Since melamine tableware is made through a heating and pressing molding process, there are many burrs and flash at the edges of the melamine tableware finished products after molding, and the products must go through a grinding process to become smoother.

[0003] In a plastic tableware edge grinding machine disclosed in the Chinese Patent Application Publication Specification CN211414654U, during grinding, the tableware can be rotated by the operation of the first motor, which is beneficial to grinding the edges of the tableware. And through the elastic action of the spring and in cooperation with the electric telescopic rod, if there is a situation where the edge position of the tableware bulges during grinding of the tableware, it is convenient to adjust the position of the tableware, and it is more convenient to use the grinding disc to grind the tableware. This setting is simple to operate, abandons the traditional manual grinding, and has high efficiency during work.

[0004] In the above patent solution, the tableware is placed on the tableware tray, and then the first electric telescopic rod is used to drive the pressing plate to fit with the tableware to fix it. However, if the applied pressure is too large, the tableware may be deformed due to excessive compression, and the tableware tray drives the tableware to rotate for edge grinding. Since the pressing plate always fits on the surface of the tableware, the pressing plate for fixing the tableware will generate friction during the rotation of the tableware, and long-term friction may leave scratches or other forms of wear on the surface of the tableware.

[0005] Therefore, an edge grinding machine for plastic tableware is proposed here. Content of the Utility Model

[0006] The utility model provides an edge grinding machine for plastic tableware, which is convenient for buffering the clamping force acting on the tableware and can also avoid leaving scratches on the surface of the tableware due to friction.

[0007] The utility model is realized through the following technical solutions: an edge grinding machine for plastic tableware, including a base and a U-shaped frame fixed on the upper surface of the base. A moving mechanism is provided on the U-shaped frame. The inner wall of the hole in the upper part of the U-shaped frame is fixed with a second electric push rod, and the bottom end of the second electric push rod is fixed with a pressing plate. A buffer mechanism is provided on the pressing plate.

[0008] The buffer mechanism includes a plurality of circular grooves formed in the pressing plate. A rubber ball is rotatably connected inside the circular groove. A fixing cylinder is fixed to the inner wall of the rubber ball. A sliding plate is slidably connected to the inner wall of the fixing cylinder. A spring is provided inside the fixing cylinder. One end of the sliding plate away from the spring is fixed with a sliding rod, and one end of the sliding rod penetrates through the fixing cylinder and is slidably connected to the inner wall of the hole of the fixing cylinder. A fixing block is fixed to the end of the sliding rod away from the fixing cylinder.

[0009] Further, a third rotating motor is fixed to the upper surface of the base. The output end of the third rotating motor is fixed with a driving gear. A rotating rod is rotatably connected to the upper surface of the base. A driven gear is fixed to the outer surface of the rotating rod, and the driven gear meshes with the driving gear.

[0010] Further, a placing plate is fixed to the top end of the rotating rod. A rubber pad is arranged on the upper surface of the placing plate.

[0011] Further, the moving mechanism includes a sliding groove formed on one side of the U-shaped frame and a first rotating motor fixed to the upper surface of the U-shaped frame. The output end of the first rotating motor is fixed with a threaded rod, and one end of the threaded rod penetrates through the U-shaped frame and is rotatably connected to the upper surface of the base. A threaded block is threadedly connected to the outer surface of the threaded rod, and the outer surface of the threaded block is slidably connected to the inner wall of the sliding groove.

[0012] Further, a first electric push rod is fixed to one side of the threaded block close to the placing plate. A second rotating motor is fixed to the end of the first electric push rod away from the threaded block. A grinding disc is fixed to the output shaft end of the second rotating motor.

[0013] Further, a controller is fixed to one side of the U-shaped frame, and the controller is electrically connected to the second electric push rod, the first rotating motor, the third rotating motor, the first electric push rod and the second rotating motor.

[0014] The utility model provides a plastic tableware edge grinding machine, and the beneficial effects thereof are as follows:

[0015] For this plastic tableware edge grinding machine, by providing the rubber ball, it can avoid scratches left on the surface of the tableware by the pressing plate when the tableware rotates. At the same time, when the clamping force on the tableware is relatively large, the rubber ball will be squeezed. At this time, the sliding rod will squeeze the spring through the sliding plate, causing it to generate corresponding elastic force. Under the action of the rubber ball and the spring, it is convenient to buffer the clamping force acting on the tableware.
