DETAILED DESCRIPTION

[0030] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1-9 As shown, a PET bottle cleaning device for dairy product filling includes a device body 1, and a plurality of bottom brackets 101 are fixedly connected to the bottom of the device body 1.

[0032] The inner wall of the device body 1 is fixedly connected with the first electric telescopic rod 2 and the second electric telescopic rod 6, the first electric telescopic rod 2 and the second electric telescopic rod 6 are arranged opposite to each other, the end of the first electric telescopic rod 2 close to the second electric telescopic rod 6 is fixedly connected with the first tooling plate 21, and the end of the second electric telescopic rod 6 close to the first electric telescopic rod 2 is fixedly connected with the second tooling plate 61, and the interior of the device body 1 is provided with an inner wall cleaning component 3, an outer shell cleaning component 4, a barrier component 5 and a current limiting component 7, the outer shell cleaning component 4 is arranged on the outside of the inner wall cleaning component 3, the barrier component 5 is arranged inside the inner wall cleaning component 3, and the current limiting component 7 is arranged in the circular groove 62.

[0033] A plurality of sleeve rods 22 are fixedly connected to one side of the first tooling plate 21 close to the second electric telescopic rod 6 . The surfaces of the sleeve rods 22 are respectively provided with a first outer hole 221 and a second outer hole 222 . The outer shell of the sleeve rods 22 is provided with a glass cup 23 .

[0034] The inner wall cleaning assembly 3 includes a rotating rod 31, which is rotatably connected to the first tooling plate 21, and is disposed in the sleeve rod 22. An inner rod 32 is slidably connected to the inner part of the rotating rod 31, and a plurality of micro-holes are formed at one end of the inner rod 32 away from the rotating rod 31, and the cleaning liquid can be sprayed out from the micro-holes to clean the inside of the glass 23;

[0035] A first spring 33 is provided inside the rotating rod 31, and the first spring 33 is sleeved on the outside of the inner rod 32. A rotating shaft 34 is provided at one end of the inner rod 32 arranged inside the rotating rod 31, and a baffle 35 is fixedly connected to the outside of the rotating shaft 34. A protrusion 36 is fixedly connected to the inner wall of the rotating rod 31, and both ends of the first spring 33 are fixedly connected to the baffle 35 and the rotating rod 31 respectively.

[0036] The shell cleaning component 4 includes a fixed plate 41, which is connected to an external driving source. When the fixed plate 41 contacts an object, the driving source drives the fixed plate 41 to continue moving until a certain pressure is reached, and then the fixed plate 41 is controlled to stop moving. When the external support is lost, the driving source drives the fixed plate 41 to move outward again until it reaches a predetermined position, in preparation for subsequent operations. The fixed plate 41 contacts the inner wall of the glass cup 23.

[0037] The fixing plate 41 is slidably connected in the first outer hole 221, and meshing teeth 42 are engraved on the bottom of the fixing plate 41. The outer wall of the rotating rod 31 is fixedly connected with a tooth ring 43, and the meshing teeth 42 and the tooth ring 43 are meshed with each other. The outer wall of the rotating rod 31 is fixedly connected with an outer short rod 44, and the inner wall of the outer short rod 44 is inserted with an inner short rod 45. The end of the inner short rod 45 away from the rotating rod 31 is fixedly connected with a cleaning block 46, and a through hole 461 is opened on the surface of the cleaning block 46. The inner wall of the sleeve rod 22 is fixedly connected with a triangular block 47.

[0038] When fixing the glass 23, the fixing plate 41 presses against the inner wall of the glass 23. When the glass 23 breaks, the fixing plate 41 loses support and continues to move outward for a distance, driving the rotating rod 31 to rotate by engaging with the gear ring 43. The cleaning block 46 loses contact with the triangular block 47 and moves into the second outer hole 222. The insertion rod 52 is separated from the contact with the center hole 53. The liquid can flow out through the center hole 53 and finally spray onto the surface of the sleeve rod 22 through the through hole 461, thereby cleaning the surface of the sleeve rod 22. Timely cleaning of the surface of the sleeve rod 22 can not only clean up the glass debris in time, but also avoid the problem of the staff being scratched by the glass during cleaning, thereby greatly improving the work efficiency.

[0039] The blocking assembly 5 includes a second spring 51 , which is arranged in the outer short rod 44 . An insertion rod 52 is fixedly connected to the inside of the outer short rod 44 . An end of the inner short rod 45 arranged in the outer short rod 44 has a center hole 53 , and the insertion rod 52 is slidably connected in the center hole 53 .

[0040] The rotating rod 31 will only rotate when the fixed plate 41 loses the support of the glass 23. When the rotating rod 31 rotates, it loses the support of the triangular block 47, the inner short rod 45 extends from the outer short rod 44, and the center hole 53 is separated from the contact with the insertion rod 52, so that the cleaning liquid can flow into the inner short rod 45 through the center hole 53 and finally spray out from the through hole 461, thereby cleaning the sleeve rod 22. When the glass 23 is broken, the fixed plate 41 is squeezed by the glass 23, so that the cleaning block 46 and the triangular block 47 are in contact, and the insertion rod 52 blocks the center hole 53 again, avoiding waste of resources, greatly reducing the waste of cleaning liquid, and improving the efficiency of resource use.

[0041] A plurality of circular grooves 62 are formed on one side of the second tooling plate 61 close to the first electric telescopic rod 2 .

[0042] The current limiting assembly 7 includes a square block 71, which is slidably connected in the through groove 611. A special-shaped rod 72 and a third spring 73 are arranged inside the through groove 611. A small hole 74 is opened at one end of the square block 71 arranged in the circular groove 62. The two ends of the third spring 73 are respectively fixedly connected to the square block 71 and the second tooling plate 61, and the special-shaped rod 72 is slidably connected in the square block 71.

[0043] When the bottom of the glass 23 moves into the second tooling plate 61, the glass 23 squeezes the square block 71 into the through groove 611. Since the special-shaped rod 72 is designed with one end larger than the other, the cleaning liquid in the through groove 611 can enter the square block 71 through the gap between the special-shaped rod 72 and the square block 71, and finally spray out through the small hole 74. When the glass 23 breaks, the square block 71 rebounds quickly under the action of the third spring 73, avoiding the waste of cleaning liquid.

[0044] Working principle: When the glass 23 is placed, the inner wall of the glass 23 pushes the inner rod 32 to move, and through the contact between the baffle 35 and the protrusion 36, the baffle 35 is driven to rotate with the rotating shaft 34 as the axis point, so that the cleaning liquid in the rotating rod 31 can be sprayed out by the inner rod 32, and the inside of the glass 23 is effectively cleaned;

[0045] When fixing the glass 23, the fixing plate 41 abuts against the inner wall of the glass 23. When the glass 23 is broken, the fixing plate 41 loses support and continues to move outward for a distance, and drives the rotating rod 31 to rotate by meshing with the gear ring 43. The cleaning block 46 loses contact with the triangular block 47 and moves into the second outer hole 222. The insertion rod 52 is separated from the contact with the center hole 53, and the liquid can flow out through the center hole 53 and finally spray onto the surface of the sleeve rod 22 through the through hole 461, thereby cleaning the surface.

[0046] The rotating rod 31 will rotate only when the fixed plate 41 loses the support of the glass 23. When the rotating rod 31 rotates, it loses the support of the triangular block 47, and the inner short rod 45 extends out from the outer short rod 44. The center hole 53 is separated from the contact with the insertion rod 52, so that the cleaning liquid can flow into the inner short rod 45 through the center hole 53 and finally spray out from the through hole 461, thereby cleaning the sleeve rod 22. When the glass 23 is broken, the fixed plate 41 is squeezed by the glass 23, so that the cleaning block 46 and the triangular block 47 are in contact, and the insertion rod 52 blocks the center hole 53 again.

[0047] When the bottom of the glass 23 moves into the second tooling plate 61, the glass 23 squeezes the square block 71 into the through groove 611. Since the special-shaped rod 72 is designed with one end larger than the other, the cleaning liquid in the through groove 611 can enter the square block 71 through the gap between the special-shaped rod 72 and the square block 71, and finally spray out through the small hole 74. When the glass 23 breaks, the square block 71 rebounds quickly under the action of the third spring 73, avoiding the waste of cleaning liquid.

[0048] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
