Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a structure for cleaning plastic bottle flakes. Background Technology

[0002] Plastic bottle flakes, also known as PET or polyester bottle flakes, often require cleaning before processing to remove surface dirt and dust, achieving a certain level of cleanliness. Current cleaning methods for plastic bottle flakes mainly involve using a washing tank with water and brushes, or using a friction cleaning machine. However, brushes don't provide comprehensive contact with the bottle surface, resulting in incomplete cleaning. Friction cleaning machines typically rely on friction between the plastic bottle flakes and the agitator blades, but the low friction leads to incomplete cleaning and poor results. Furthermore, the plastic surface often has hard-to-reach areas, further contributing to incomplete cleaning and low efficiency. Additionally, the process involves pouring water into the machine, washing once, emptying, and then refilling with water for another wash, wasting water resources.

[0003] Therefore, based on customer feedback regarding the shortcomings of the existing structure, the inventors made further improvements to overcome the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a structure for cleaning plastic bottle flakes that is cleaner, more efficient, and saves water resources.

[0005] The purpose of this utility model is achieved through the following technical solution: a structure for cleaning plastic bottle flakes, including a cleaning tank, a cleaning cylinder and a cleaning rod;

[0006] The cleaning tank is rotatably provided with a cleaning cylinder and the cleaning rod is rotatably inserted into the cleaning cylinder;

[0007] The inner wall of the cleaning cylinder is provided with a cleaning brush A, and the body of the cleaning cylinder is provided with a sieve hole; the cleaning rod includes a cleaning brush B and a spring plate; the cleaning rod is provided with a spring plate, and the cleaning brush B is movably connected to the cleaning rod via a spring in the spring plate; a cover is also provided on the body of the cleaning cylinder, and the cover can rotate around the cleaning cylinder to cover the sieve hole.

[0008] After the plastic bottle flakes and clean water are put into the cleaning cylinder, the cleaning cylinder and the cleaning rod are driven to rotate in opposite directions. The cleaning brush A cooperates with the cleaning brush B on the cleaning rod, and the cleaning brush B fits tightly against the plastic bottle flakes in the cleaning cylinder to thoroughly wash the dirt and dust on the plastic bottle flakes. At this time, the cover rotates to block the screen holes, and the rotation of the cleaning cylinder can repeatedly clean the plastic bottle flakes. After washing, the cover is removed, and the wastewater flows out through the screen holes.

[0009] As a preferred technical solution of this application, a motor A is fixedly installed on one side plate of the cleaning tank. The motor A extends through the side plate with a rotating shaft and its end is connected to the circular side surface of the cleaning cylinder. The motor A drives the rotating shaft to rotate, thereby driving the cleaning cylinder to rotate. Multiple cleaning brushes A are evenly distributed around the circumference in the cleaning cylinder.

[0010] As a preferred technical solution of this application, the cleaning cylinder has one half smooth and the other half with multiple screen holes, and an openable feed inlet is provided on the smooth part of the cylinder. When the cleaning cylinder is rotated by motor A, the cover blocks all the screen holes. After cleaning, the cleaning cylinder rotates to the screen holes facing down, the cover rotates to the smooth part, and the sewage flows out from the screen holes.

[0011] As a preferred technical solution of this application, the shielding cover includes a gear; the shielding cover is a semi-cylindrical shell that can be adapted to be installed on the outer periphery of the cleaning cylinder and a gear edge is provided on one side edge of the shielding cover. A rotatable gear is installed on one side of the shielding cover, and the gear meshes with the gear edge of the shielding cover. When the gear rotates, the meshing shielding cover rotates, thereby shielding the sieve holes.

[0012] As a preferred technical solution of this application, the two circular edges of the cleaning cylinder are provided with annular protrusions and the two ends of the cover are provided with corresponding grooves, and the annular protrusions and grooves are fitted together.

[0013] As a preferred technical solution of this application, the spring disc includes a disc shell and a spring; the disc is fixedly sleeved on the outside of the cleaning rod, and multiple through holes are opened on the periphery of the disc; the front of the cleaning brush B is a brush surface, and a connecting rod protrudes vertically from its back. The connecting rod passes through the through hole and is movably connected to the cleaning rod through the spring. One end of the spring is connected to the cleaning rod, and the other end is connected to the connecting rod. When the brush surface is squeezed, the spring is compressed and drives the connecting rod to retract into the disc.

[0014] As a preferred technical solution of this application, a movable sewage frame is inserted into the cleaning tank, and the sewage frame is located below the cleaning cylinder.

[0015] This utility model has the following advantages:

[0016] (1) Cleaning is more thorough, avoiding the accumulation of dirt in dead corners on the surface of the bottle due to incomplete cleaning;

[0017] During friction cleaning, the cleaning effect is not good because the stirring rod does not fully contact the plastic bottle flakes and the friction force is relatively small. It also fails to clean some hard-to-reach areas of the plastic bottle flakes. This solution uses a rotatable cleaning cylinder and a cleaning rod that rotates in the opposite direction to the cylinder to achieve a stronger cleaning force. The combination of cleaning brush A and cleaning brush B can thoroughly clean the bottle flakes. Cleaning brush B is in constant contact with the surface of the plastic bottle flakes to scrub, and it can also thoroughly clean the hard-to-reach areas of the bottle flakes, resulting in a better cleaning effect and higher efficiency.

[0018] (2) Repeatedly wash the plastic bottle flakes to avoid wasting water resources;

[0019] After pouring plastic bottle flakes and clean water into the cleaning cylinder, the feed inlet is closed, and the cover is rotated to block the sieve holes on the cleaning cylinder, making the cleaning cylinder closed. After repeatedly rotating the cylinder to thoroughly clean the bottle flakes, the cover is rotated to remove it from the sieve hole position to release the wastewater. This not only cleans more thoroughly but also avoids wasting water resources. Attached Figure Description

[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0032] Therefore, based on the above issues, please refer to Figure 1 This utility model proposes a structure for cleaning plastic bottle flakes to solve the problem.

[0033] (Example)

[0034] See Figures 1 to 8 The present embodiment proposes a structure for cleaning plastic bottle flakes, including a cleaning tank 1, a cleaning cylinder 2, and a cleaning rod 12;

[0035] Among them, see Figures 1-3 The cleaning cylinder 2 is installed in the cleaning tank 1 and is rotatably installed in the cleaning tank 1 driven by the motor A4. At the same time, the cleaning rod 12 is rotatably inserted into the cleaning cylinder 2.

[0036] Among them, see Figure 5 Multiple cleaning brushes A8 are arranged at equal intervals around the inner wall of the cleaning cylinder 2, and the cleaning cylinder 2 is a semi-sieve cylinder with multiple sieve holes 7 opened on a part of its body for sewage to flow out; the cleaning rod 12 is driven by the motor B5 and a cleaning brush B9 is installed on the rod body of the cleaning rod 12 inserted into the cleaning cylinder 2, and the cleaning brush B9 is movably connected to the cleaning rod 12 via the spring 10.

[0037] Among them, see Figure 2 and Figure 6A cover 13 is also installed on the outer periphery of the cleaning cylinder 2. The cover 13 rotates around the body of the cleaning cylinder 2 and can block the screen hole 7 during the rotating cleaning process. After the cleaning is completed, it is removed to discharge the wastewater.

[0038] During operation, multiple plastic bottle flakes and clean water are poured into the cleaning cylinder 2. The drive motors A4 and B5 cause the cleaning cylinder 2 and the cleaning rod 12 to rotate synchronously, and the two rotate in opposite directions, so as to better clean the dirt on the surface of the plastic bottle flakes. The cleaning brushes A8 and B9 work together to brush, and the cleaning brush B9 is in close contact with the plastic bottle flakes under the action of the spring 10. The plastic bottle flakes are repeatedly cleaned by the rotation of the cleaning cylinder 2. During cleaning, the cover 13 rotates to cover the screen hole 7. After cleaning, the cover 13 is removed, and the sewage flows down through the screen hole 7.

[0039] Existing cleaning structures often fail to fully clean the surface of plastic bottles when using brushes, resulting in incomplete cleaning. Alternatively, the friction used in agitation methods is too low, leading to poor cleaning and leaving blind spots on the plastic surface, further contributing to incomplete cleaning. This design proposes a new structure for cleaning plastic bottles. A cleaning cylinder 2 and a cleaning rod 12 work together and rotate in opposite directions. The cleaning cylinder 2 contains a cleaning brush A8, and the cleaning rod 12 is movably connected to a cleaning brush B9. This combination allows for vigorous cleaning of the plastic bottles during rotation. The cleaning brush B9, acted upon by a spring 10, adheres tightly to the plastic bottles, resulting in a more thorough cleaning and preventing dirt from accumulating in blind spots on the plastic surface.

[0040] In this embodiment, see Figure 1 For the cleaning tank 1, motor A4 is fixedly mounted on the left side plate of the cleaning tank 1, and the rotating shaft of motor A4 extends through the side and connects to the left end circular side of the cleaning cylinder. Motor A4 can drive the cleaning cylinder 2 to rotate. Motor B5 is mounted on the inside of the right side plate of the cleaning tank 1 and is fixedly connected to the right side plate through a triangular mounting seat. The rotating shaft of motor B5 extends and is connected to the cleaning rod 12. Motor B5 drives the cleaning rod 12 to rotate. A sewage frame 3 is movably inserted into the lower part of the cleaning tank 1 (i.e., below the cleaning cylinder 2). A handle is installed on the outside of the sewage frame 3 for easy pulling. The sewage flowing down from the screen hole 7 can be easily collected and treated through the sewage frame 3.

[0041] In this embodiment, see Figures 1-5For the cleaning cylinder 2, four cleaning brushes A8 are evenly distributed inside the cleaning cylinder 2. The back of the cleaning brush A8 is an arc surface that fits against the inner wall of the cylinder and is fixedly connected. Its front is a brush surface to scrub the dirt on the surface of the plastic bottle flakes. The upper half of the cylinder of the cleaning cylinder 2 is smooth, and the lower half has multiple sieve holes 7. A feed inlet 17 is opened at the center of the upper smooth surface. The feed inlet 17 can be manually opened and closed. A cover 13 is movably installed on the outer periphery of the cleaning cylinder 2. The cover 13 is a semi-cylindrical shell that is fitted to the outside of the cleaning cylinder 2. A gear edge is set on one side edge of the cover 13. 15. At the same time, a rotatable gear 14 is set next to the shielding cover 13. The motor C6 that drives the gear 14 to rotate is fixedly set inside the right side plate of the cleaning tank 1 through a triangular mounting seat. The gear 14 meshes with the gear side 15 of the shielding cover 13. When the driving motor C6 makes the gear 14 rotate, the meshing shielding cover 13 rotates around the cleaning cylinder 2. When cleaning the plastic bottle flakes, the shielding cover 13 covers the sieve hole 7, so that the bottle flakes can be repeatedly agitated and cleaned inside the cleaning cylinder 2. After cleaning, the cleaning cylinder 2 rotates to the point where the sieve hole 7 faces down, the shielding cover 13 rotates and moves away, and the sewage flows out.

[0042] Furthermore, a switch door is installed on the feed inlet 17 to open and close the feed inlet 17.

[0043] Furthermore, a circular protrusion 16 is provided on the left and right circular edges of the cleaning cylinder 2, and corresponding grooves are provided on the two ends of the cover 13. The circular protrusion 16 fits into the groove, which makes the cover 13 more stable when it rotates and prevents slippage.

[0044] In this embodiment, see Figure 3 and Figures 7-8 The cleaning rod 12 includes a disc 18, a spring 10, and a cleaning brush B9. Two discs 18 are installed on the rod part of the cleaning rod 12 that is inserted into the cleaning cylinder 2. One disc 18 is installed at the top end of the cleaning rod 12 and the other disc 18 is installed at the tail end of the cleaning rod 12. The discs 18 are fixedly installed. Four through holes are equally spaced on the cylindrical side surface of the disc 18 (i.e., the periphery of the disc 18). The front of the cleaning brush B9 is a brush surface, and a connecting rod 11 extends vertically from its back. The connecting rod 11 passes through the through hole and is connected to the cleaning rod 12 by the spring 10. One end of the spring 10 is connected to the cleaning rod 12, and the other end is connected to the connecting rod 11, thereby connecting the cleaning brush B9 and the cleaning rod 12 together. When the brush surface contacts the surface of the plastic bottle, the cleaning brush can be tightly attached to the plastic bottle for cleaning by the compression and extension of the spring 10.

[0045] When cleaning plastic bottle flakes, the plastic bottle flakes are poured into the cleaning cylinder 2 through the feed port 17, and a certain amount of clean water is added at the same time. At this time, the cover 13 blocks the sieve hole 7. The motors A4 and B5 are started, so that the cleaning cylinder 2 and the cleaning rod 12 rotate in opposite directions. The cleaning brushes A8 and B9 work together to brush the plastic bottle flakes. After repeated agitation in the cleaning cylinder 2, the cleaning is completed. The drive motor C6 drives the gear 14 to rotate, so that the cover 13 is removed and the sewage flows through the sieve hole 7 into the sewage frame 3.

[0046] Current cleaning structures often fail to clean thoroughly due to incomplete contact with the target plastic bottles, or the cleaning effect is poor due to insufficient friction during stirring and friction cleaning. Furthermore, dead corners on the plastic surface are easily missed, resulting in very low cleaning efficiency. Additionally, during cleaning, water is poured into the device, washed once, poured out, and then poured in again for repeated washing, leading to incomplete cleaning and wasted water resources. This solution designs a structure for cleaning plastic bottles. Through the cooperation of the cleaning cylinder 2 and the cleaning rod 12, a motor drives them to rotate in opposite directions. This allows the cleaning brush A8 on the inner wall of the cleaning cylinder 2 and the cleaning brush B9 on the cleaning rod 12 to clean the plastic bottles more thoroughly. The cleaning brush B9, due to the action of the spring 10 inside the disc 18, can adhere to the surface of the plastic bottles, effectively preventing the cleaning of dead corners during the cylinder process. A cover 13 is also provided to block the sieve holes 7. The movable cover saves water resources. Only after thorough cleaning is completed is the wastewater released from the sieve holes 7.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
