[0028] like Figure 1-3 As shown, the present application provides a PET bottle bottom mold grinding device, including a working platform 1, a grinding motor 2 and a protective cover 3 are fixed on the working platform 1, the output shaft of the grinding motor 2 extends into the protective cover 3, a grinding wheel 4 is provided in the protective cover 3, the grinding wheel 4 is fixed on the output shaft of the grinding motor 2, an operating port 31 is provided on one side of the protective cover 3, and the diffusion range of dust and debris generated during grinding can be reduced by the setting of the protective cover 3, a water tank 5 is provided on the working platform 1, the water tank 5 is located below the grinding wheel 4, a grille 6 is provided on the water tank 5, and a water spray component 7 for spraying water during grinding is provided on the working platform 1, wherein when the water spray component 7 sprays water on the PET bottom film, the water is mixed with dust and debris and then flows downward It passes through the grille 6 and falls into the water tank 5, and the grille 6 can prevent the operator from accidentally operating the PET bottle bottom mold and causing it to fall into the water tank 5 during grinding. When in use, start the grinding motor 2, the grinding motor 2 drives the grinding wheel 4 to rotate, and then the PET bottle bottom mold is held and inserted into the protective cover 3 through the operation port 31, and the rotating grinding wheel 4 is used to grind the PET bottle bottom mold. At the same time, the water spray component 7 sprays water on the PET bottle bottom mold, so that the PET bottle bottom mold is grinded in a wet grinding manner, which effectively reduces the dispersion of dust and debris. The dust, debris and water are mixed and fall into the water tank 5 for precipitation and collection, which effectively protects the hygiene of the working environment, reduces the labor of cleaning personnel, and avoids the dispersion of dust and debris that endangers the health of the staff.

[0029] like Figure 3As shown, the water spray assembly 7 includes a water spray pump 71, a water pipe 72, a water spray hose 73 and a clamping seat 74. The water spray pump 71 is fixed on the working platform 1 and is located outside the protective cover 3. One end of the water pipe 72 is connected to the water inlet of the water spray pump 71, and the other end of the water pipe 72 extends into the protective cover 3 and is connected to the water tank 5. One end of the water spray hose 73 is connected to the water outlet of the water spray pump 71. The clamping seat 74 is located in the protective cover 3. The other end of the water spray hose 73 extends into the protective cover 3 and is clamped on the clamping seat 74. When polishing the bottom mold, first pour water into the water tank 5, and then start the water spray pump 71. The water spray pump 71 sprays the water in the water tank 5 to the PET bottle bottom mold through the water pipe 72 and the water spray hose 73, so that the PET bottle bottom mold is polished under the flushing of the water flow, so that dust, debris and water are mixed to prevent dust and debris from floating. The clamping seat 74 clamps the water spray hose 73 and directs the water spray port toward the PET bottle bottom mold. There is no need to hold the water spray hose 73 and direct the water spray port toward the PET bottle bottom mold, which makes it convenient for the staff to polish the PET bottle bottom mold.

[0030] like Figure 1 and Figure 3 As shown, the grille 6 is a cast iron grille, and a magnet 8 is fixed to the bottom of the clamping seat 74. The clamping seat 74 is adsorbed on the grille 6 by the magnet 8, which makes it convenient for the staff to move the clamping seat 74 according to actual needs and adjust the water spraying direction of the water spray hose 73.

[0031] like Figure 3 As shown, a filter assembly 9 is provided in the water tank 5, which divides the water tank from left to right into a first tank chamber 10 and a second tank chamber 11. The water pipe 72 is connected to the second tank chamber 11. Dust, debris and water are mixed and fall into the first tank chamber 10 of the water tank 5. After filtering by the filter assembly 9, the water pump 71 extracts the filtered water from the second tank chamber 11 through the water pipe 72, and then sprays water to the PET bottle bottom film through the water hose 73, thereby realizing water recycling. At the same time, the filter assembly 9 can prevent dust and debris in the water in the water tank 5 from being sprayed onto the PET bottle bottom film, thereby preventing the polishing quality of the PET bottle bottom film from being affected.

[0032] like Figure 3 As shown, the filter assembly 9 includes a first filter screen 91 and a second filter screen 92. The first filter screen 91 and the second filter screen 92 are both vertically inserted into the water tank 5. An activated carbon filter layer 12 is provided between the first filter screen 91 and the second filter screen 92. Specifically, the inner wall of the water tank 5 is provided with a slot compatible with the first filter screen 91 and the second filter screen 92. The first filter screen 91 and the second filter screen 92 can be inserted into the water tank 5 through the corresponding slots. The first filter screen 91 and the second filter screen 92 are used to filter the water in the water tank 5, and the activated carbon filter layer 12 is used to adsorb and filter dust and debris in the water in the water tank 5.

[0033] like Figure 1 and Figure 3 As shown, the grille 6 is detachably connected to the water tank 5, and a support block 13 is fixed to the inner wall of the water tank 5. The bottom of the grille 6 abuts against the support block 13. Specifically, the grille 6 can be lifted upward to separate the grille 6 from the water tank 5, making it convenient for the staff to clean the dust and debris in the water tank 5.

[0034] like Figure 1 and Figure 3 As shown, a blind plate area 61 is provided on the grille 6, and the blind plate area 61 covers the top of the second tank chamber 11. The blind plate area 61 on the grille 6 can prevent the sewage formed by the mixture of dust, debris and water from falling into the second tank chamber 11 when the PET bottle bottom film is polished, thereby avoiding the presence of dust and debris in the water in the second tank chamber 11.

[0035] like Figure 3 As shown, a drain pipe 14 communicating with the first tank chamber 10 is provided at the bottom of the water tank 5, and the water outlet of the drain pipe 14 extends to the bottom of the working platform 1. A drain valve 15 is provided on the drain pipe 14. When the water in the water tank 5 needs to be replaced, the sewage in the first tank chamber 10 in the water tank 5 can be discharged by opening the drain valve 15, and then the grille 6 is lifted to separate the grille 6 from the water tank 5, and the inner wall of the first tank chamber 10 in the water tank 5 is cleaned. According to actual needs, the first filter screen 91 and the second filter screen 92 are taken out for cleaning, and the activated carbon filter layer 12 is taken out, and the inner wall of the water tank 5 is rinsed with water several times. After rinsing, the drain valve 15 is closed, and new water is poured into the water tank 5. Finally, the first filter screen 91 and the second filter screen 92 are returned to their positions, the activated carbon filter layer 12 is rinsed and filled, and then the grille 6 is returned to its position.

[0036] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
