[0002] Currently, in the production process of rubber products, after molded, rubber products must undergo grinding, cleaning, drying, and screening before they can be packaged and stored. However, the molded rubber products often have overflow waste from the tiny sealing gaps at the mold closing, or excess thin and scrap waste is formed after the integral molding process. These wastes require the use of a grinding and cleaning machine to grind and clean the rubber products. For example, utility model patent No. CN215031711U discloses a grinding and cleaning machine for processing and producing seals. The machine comprises an outer barrel, on which a motor and a drive shaft are mounted, the drive shaft being mounted on the motor's rotating shaft, and an inner barrel sleeved within the outer barrel, with a water hole provided in the inner barrel. This patent lifts the inner barrel, trapping the seal within the inner barrel, thereby allowing the seal to be removed in one go. However, after rubber products such as seals are ground and cleaned using the above-mentioned traditional grinding and cleaning equipment, a large amount of debris will adhere to the inner ring of the product, which is difficult to remove and significantly reduces the quality of the product.

The following is a detailed description of the various components of this embodiment in conjunction with the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, the grinding barrel 2 can be installed between the two sides of the frame 1 and is located above the base 11 of the frame 1. The top of the grinding barrel 2 is open and forms a feed port 21. The bottom opening of the grinding barrel 2 forms a discharge port 22 for discharging grinding cleaning liquid and debris. The blades 4 are provided with a plurality of pieces and are respectively arranged on the inner wall of the grinding barrel 2 at an angle and at intervals. A rotating inner disk 23 is movably provided inside the grinding barrel 2, and a plurality of through holes 24 are opened on the bottom surface of the rotating inner disk 23.

[0026] In this embodiment, the lifting drive device 6 can be installed at the bottom of the grinding barrel 2, and the cover plate 3 is movably set at the bottom of the rotating inner disk 23 and above the discharge port 22 through the lifting drive device 6. The rotating drive device 5 is installed at the bottom of the rotating inner disk 23 and is transmission-connected to the rotating inner disk 23.

[0027] like Figure 3 As shown, the cross-sectional shape of the rotating inner disk 23 can be L-shaped. The rotating inner disk 23 includes a rotating disk 231 and a connecting pipe 232. The connecting pipe 232 is located on the top surface of the rotating disk 231. The connecting pipe 232 protrudes upward from the center of the bottom surface of the rotating disk 231 and is provided with a pipe mouth 233 on its top surface. A plurality of ribs 234 are protruded on the top surface of the rotating disk 231, and the through holes 24 are all set through the rotating disk 231.

[0028] Specifically, the inner wall of the grinding barrel 2 may be surrounded by a plurality of radially distributed grinding ridges 26 , and the outer wall edge of the rotating disk 231 is curved inward and abuts against the bottom surface of the grinding ridges 26 .

[0029] During specific implementation, the plastic product is poured into the interior of the grinding barrel 2 through the feed port 21, and the rotating inner disk 23 is driven by the rotary drive device to rotate. The grinding ridges 26 on the grinding barrel 2 are capable of grinding away the overflow waste or scrap waste on the plastic product and forming the waste into debris.

[0030] like Figure 4 As shown, a mounting hole 31 for mounting the rotary drive device 5 and corresponding to the pipe opening 233 may be opened in the middle of the cover plate 3 .

[0031] Preferably, the rotary drive device 5 may include a rotary drive motor 51, a rotary shaft 52 and a rotary shaft cap 53. The rotary drive motor 51 passes upward through the mounting hole 31 and is fixed on the bottom surface of the cover plate 3. One end of the rotary shaft 52 is transmission-connected to the output portion of the rotary drive motor 51. The other end of the rotary shaft 52 passes through the connecting pipe 232 and is fixedly connected to the rotary shaft cap 53. A moving space is left between the rotary shaft cap 53 and the connecting pipe 232.

[0032] like Figure 5 As shown, a supporting hollow plate 7 may also be included. The supporting hollow plate 7 is embedded at the discharge port 22 at the bottom of the grinding barrel 2 , and two connecting horizontal bars 71 are connected to the supporting hollow plate 7 at intervals.

[0033] In this embodiment, the lifting drive device 6 can include two lifting cylinders 61, which are fixedly installed upward on the top surfaces of the two connecting horizontal bars 71, and the output parts of each lifting cylinder 61 are respectively connected to the two sides of the bottom surface of the cover plate 3 for transmission.

[0034] In practice, the cover plate 3 is driven by two lifting cylinders 61 to move up and down toward or away from the bottom surface of the rotating inner disk 23, thereby opening or closing the through-holes 24 of the rotating disk 231. In a normal state, the cover plate 3 abuts against the bottom surface of the rotating inner disk 23, and the through-holes 24 on the rotating inner disk 23 are in a normally closed state.

[0035] like Figure 6 As shown, it can also include a chassis 8, one side of the chassis 8 is fixedly connected to one side of the grinding barrel 2, a first fixing boss 28 is provided on the other side of the grinding barrel 2, and a second fixing boss 81 is provided on the other side of the chassis 8. Fixing holes 12 are relatively provided in the middle of both sides of the frame 4, and the chassis 8 and the grinding barrel 2 are rotatably connected to the two fixing holes 12 through their respective first fixing bosses 28 and second fixing bosses 81, thereby realizing that the two are installed between the two sides of the frame 1.

[0037] Preferably, an electric control device 9 may be provided on one side of the rack 1 , and the electric control device 9 includes a display screen 91 , control buttons 92 and a switch button 93 .

[0038] The working principle of this embodiment is as follows:

[0039] First, place the plastic product in the cleaning liquid in the grinding barrel. Water is continuously added to the grinding barrel to immerse the product. The switch button of the electronic control device is turned on. The rotary drive device then drives the rotating inner disk to rotate, grinding and cleaning the plastic product back and forth. Due to the mutual collision and compression of individual products during the rotation process, and the stirring and grinding with the grinding ridges on the inner wall of the grinding barrel and the ribs on the rotating disk, the waste material on the plastic product can be ground and removed to form debris. Driven by the rotation of the rotating inner disk, the blades cause the water flow to move in a turbulent and high-speed manner. The cleaning liquid can generate a large number of bubbles in the grinding barrel, forming a cavitation effect, which can fully separate the debris from the product. When drainage is required, the cover plate is driven downward by the lifting drive device, which also drives the rotary drive device downward, so that the top surface of the shaft cap contacts the top surface of the connecting pipe. The water flow drives the debris downward through the through-holes of the rotating disk and is collected in the waste trough. Finally, it is discharged from the waste trough through the drain pipe connected to the drain outlet.

[0040] In summary, the utility model adds blades to the inner wall of the grinding barrel and opens a plurality of through holes on the bottom surface of the rotating inner disk. The plastic product is immersed in the cleaning liquid in the grinding barrel. The rotating inner disk is driven by a rotary drive device to rotate to grind and clean the plastic product back and forth, and the waste material on the plastic product can be ground and removed to form debris. The blades cause the water flow to move in a turbulent and high-speed manner and generate a large number of bubbles in the grinding barrel to form a cavitation effect, which can fully separate the debris from the product and effectively solve the problem of debris adhering to the inner circle of the product.

[0041] The above embodiments are preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
