Description

Technical Field

[0001] The invention relates to the technical field of curved surface grinding, and more specifically to a curved surface grinding device and method for processing plastic toys. Background Art

[0002] According to the plastic molding process, it is divided into injection molding toys, blow molding toys, roto-molding toys, slush molding toys, inflatable toys, etc. ① Injection molding toys. The raw materials are heated into liquid by an injection molding machine, injected into the mold and cooled to form. Such as cars, electronic piano shells, etc. ② Blow molding toys. The raw materials are heated and extruded by an extruder to become a cylindrical semi-liquid state, and then enter the split mold, inflate and mold after the mold is closed, and then cooled and fixed. Such as dolls, two-color balls, etc. ③ Roto-molding toys. The raw materials are placed in the mold, sealed and fixed on the bracket, and then placed in the roto-molding machine and rotated at a certain speed and heated. After the raw materials are formed, they are taken out and cooled. Such as dolls, animals, balls, etc. ④ Slush molding toys. Similar to roto-molding toys, due to uneven product thickness and low efficiency, they have now been basically eliminated. ⑤ Inflatable toys. After the polyvinyl chloride film is cut into a certain shape and printed with a pattern, it is pressed and heated by an electronic heat sealing machine with a mold, and then the inflatable nozzle is bonded, and it can be played after inflating. Such as swimming rings, water balls, animals, etc.

[0003] After the plastic toy is injection molded, the plastic is squeezed during the injection molding process and overflows from the mold, resulting in excess scraps at the bonding point of the plastic toy that need to be trimmed and polished. Generally, the operator trims the excess overflow and then uses tools to polish the injection molding bonding point.

[0048] Processing seat 1;

[0049] A dust cover 2 is used to suppress the flying of dust generated by processing. The dust cover 2 is fixedly connected to the processing seat 1. A motor 3 is arranged on the back of the dust cover 2. The output shaft of the motor 3 is fixedly connected to the dust cover 2. A driving rod 4 is fixedly connected to the output shaft of the motor 3. The driving rod 4 passes through the dust cover 2 and extends to the inside of the dust cover 2. A discharge port 5 is opened on the back of the dust cover 2;

[0050] The dust cover 2 not only plays a role in dust suppression, but also plays a role in fixing the motor 3;

[0051] The overall shape of the dust cover 2 is a right-angled trapezoid, which is neither parallel nor perpendicular to the side of the processing seat 1 as the front side. The reason is that the inclined surface makes it easier for the operator to observe the inside of the dust cover 2 through the observation window 23 provided on this surface.

[0052] like Figure 1 As shown, the motor 3 is arranged on the back of the dust cover 2, and the output shaft of the motor 3 is fixedly connected to the back of the dust cover 2, in order to prevent the motor 3 from rotating;
