The cutting mechanism includes a grinding head 29, and the grinding head 29 is fixedly connected to the output shaft of the driving motor 22. A blade 30 is fixedly connected to the grinding head 29. A connecting plate 25 is fixedly connected to the bottom end of the moving block 21, and the bottom end of the connecting plate 25 is fixedly connected to the cylinder 28. The bottom end of the cylinder 28 is fixedly connected to the support block 24, and the support block 24 is fixedly connected to the column 20.

[0037] The omnidirectional removal mechanism is designed to remove burrs from the PET bottle in all directions. The omnidirectional removal mechanism is composed of a cutting mechanism, a clamping mechanism and a reciprocating mechanism. The cutting mechanism, the clamping mechanism and the reciprocating mechanism can remove burrs on the bottle mouth, the bottle body and the bottle bottom respectively. The burr removal function at the bottle mouth is realized by the structural design of the cutting mechanism. At the same time, when the grinding head 29 is inserted into the bottle mouth to remove the burrs, the blade 30 fixed on the grinding head 29 will abut against the bottle mouth and cut off the excess material on the bottle mouth by rotating. When working, the cylinder 28 pulls the connecting plate 25 to move downward, and the top of the connecting plate 25 is connected to the bottom of the moving block 21, and the rear end of the moving block 21 will slide on the column 20. When the moving block 21 moves downward, the grinding head 29 can be inserted into the bottle mouth, and the burrs on the bottle mouth can be removed by starting the driving motor 22. A blade 30 is also fixed on the grinding head 29, and the blade 30 will cut off the excess material of the bottle mouth when it is close to the bottle mouth. The bottom end of the cylinder 28 is fixed on the supporting block 24, and the supporting block 24 is L-shaped and fixed on the column 20.

[0038] Further, the clamping mechanism includes two groups of grinding cylinders 32, the top and bottom ends of the rotating shafts of the grinding cylinders 32 are both rotatably connected to the retaining frame 36, the retaining frame 36 is fixedly connected with a mounting rod 39, the mounting rod 39 is inserted on the fixing frame 40, the bottom end of the fixing frame 40 is fixedly connected to the base 1, the mounting rod 39 is fixedly connected with a spring 38, the side of the spring 38 close to the retaining frame 36 is fixedly connected to the fixing frame 40, the rear end of the retaining frame 36 is fixedly connected with a protrusion 37, the protrusion 37 is slidably connected to the inside of the guide rod 27, the guide rod 27 is fixedly connected to the bottom end of the connecting rod 26, and the top end of the connecting rod 26 is fixedly connected to the connecting plate 25;

[0039] The structural design of the clamping mechanism realizes the function of removing burrs on both sides of the PET polyester bottle. When the grinding head 29 moves downward to remove the burrs on the bottle mouth, the guide rod 27 pushes the protrusion 37 to move, so that the two groups of grinding cylinders 32 are close to each other, so that the grinding cylinders 32 can keep in contact with the bottle body, and when the grinding head 29 is lifted upward, the two groups of grinding cylinders 32 can also move away from each other for easy operation. During operation, when the cylinder 28 pulls the connecting plate 25 to move downward, the guide rod 27 also moves downward, and the inside of the guide rod 27 is slidably connected with the protrusion 37. Therefore, the protrusion 37 is pushed to move through the contact between the inside of the guide rod 27 and the protrusion 37, thereby pushing the retaining frame 36 to move, and the spring 38 fixed on the retaining frame 36 will be stretched. At this time, the two groups of grinding cylinders 32 will approach each other until they are in contact with the bottle body. The two groups of grinding cylinders 32 can clamp and fix the bottle body, and the burrs on the bottle body can be removed when the grinding cylinder 32 rotates.

[0040] Further, the reciprocating mechanism includes a rotating disk 44, the top of the rotating disk 44 is fixedly connected with a fixed column 42, the fixed column 42 is in contact with the inner wall of the moving frame 41, the front and rear sides of the moving frame 41 are slidably connected with a fixed block 45, the fixed block 45 is fixedly connected to the inner wall of the base 1, the top of the moving frame 41 is fixedly connected with a mounting block 43, the top of the mounting block 43 is fixedly connected with a connecting block 49, the top of the connecting block 49 is fixedly connected with a grinding block 60, and the bottom end of the rotating disk 44 is provided with a driving mechanism;

[0041] During operation, when the rotating disk 44 rotates, the fixed column 42 fixed on the top of the rotating disk 44 will push the mobile frame 41 to move, and the front and rear sides of the mobile frame 41 slide on the fixed block 45, so the mobile frame 41 will reciprocate in the front and rear directions. The top of the mobile frame 41 is connected to the connecting block 49 through the mounting block 43, and the grinding block 60 fixed on the top of the connecting block 49 can remove burrs on the bottom of the bottle, wherein a corresponding groove of the connecting block 49 is opened on the base 1 to ensure the normal movement of the connecting block 49.

[0042] Furthermore, the driving mechanism includes a servo motor 48, the output shaft of the servo motor 48 is fixedly connected to the bottom end of the rotating disk 44, the bottom end of the servo motor 48 is fixedly connected to the mounting plate 47, the mounting plate 47 is fixedly connected to the inner wall of the base 1, the left and right sides of the rotating disk 44 are both meshed with the gear 35, the gear 35 is fixedly connected to the connecting rod 34, the top end of the connecting rod 34 is fixedly connected to the bottom end of the rotating shaft of the grinding cylinder 32;

[0043] When working, start the servo motor 48, which will first drive the rotating disk 44 to rotate. Since the left and right sides of the rotating disk 44 are meshed with the gear 35, the rotation will be transmitted to the gear 35. The top of the gear 35 is connected to the rotating shaft of the grinding cylinder 32 through the connecting rod 34, thereby driving the grinding cylinder 32 to rotate. The grinding cylinder 32 can normally remove the burrs on the bottle body, wherein a groove corresponding to the connecting rod 34 is opened on the base 1 to ensure the normal movement of the connecting rod 34.

[0044] Furthermore, a fixing seat 50 is fixedly connected to the base 1. The fixing seat 50 is annular in design. Notches 54 are provided on the left and right sides of the fixing seat 50. The top of the fixing seat 50 fits with the bottom of the clamping block 51. The bottom of the clamping block 51 is rotatably connected to the pushing rod 53. The front end of the pushing rod 53 is rotatably connected to the pushing block 55. The middle of the pushing block 55 is penetrated by a rotating rod 57. The front and rear sides of the rotating rod 57 are rotatably connected to the supporting seat 58. The front end of the rotating rod 57 is fixedly connected to the handle 52. A thread is provided at a position of the rotating rod 57 near the rear end. The rotating rod 57 is threadedly connected to the pushing block 55. A groove 59 is provided on the clamping block 51. The bottom end of the inner wall of the groove 59 is kept level with the top of the grinding block 60.

[0045] When working, first turn the handle 52, the handle 52 drives the rotating rod 57 to rotate, and the rear end of the rotating rod 57 is threadedly connected with a pushing block 55, which drives the pushing block 55 to move backward. The pushing block 55 is rotatably connected to the two groups of pushing rods 53, so it will push the two groups of pushing rods 53 to move, and the rear end of the pushing rods 53 is rotatably connected to the clamping block 51, and a U-shaped groove is also provided on the fixed seat 50 to ensure the normal movement of the clamping block 51, and also to limit the moving direction of the clamping block 51. At this time, the two groups of clamping blocks 51 will move away from each other, and the PET polyester bottle can be smoothly placed between the two groups of clamping blocks 51, and ensure that the bottom of the bottle is in contact with the bottom end of the inner wall of the groove 59, and then the handle 52 is rotated in the opposite direction, and the two groups of clamping blocks 51 will move closer to each other until the PET polyester bottle is clamped, thereby completing the PET polyester bottle. When the PET bottle is fixed, when the bottle body needs to be rotated so as to grind and remove burrs from different positions of the bottle body, when the drive motor 22 and the servo motor 48 are no longer rotating, the handle 52 is rotated again to move the two groups of clamping blocks 51 away from each other, thereby reducing the clamping force of the clamping blocks 51 on the PET bottle. At this time, the PET bottle can be smoothly rotated between the two groups of clamping blocks 51, so as to adjust the fixing angle of the PET bottle and remove burrs on the bottle body. The push block 55 can smoothly push the push rod 53 by moving a short distance on the rotating rod 57, so as to move the two groups of clamping blocks 51 away from each other. Therefore, when fixing the PET bottle and releasing the clamping block 51 from fixing the PET bottle, the handle 52 only needs to be rotated a small number of times, thereby facilitating operation.

[0046] Furthermore, the front end of the push block 55 abuts against the limit ring 56, and the limit ring 56 is fixedly connected to the rotating rod 57;

[0047] During operation, the limiting ring 56 is fixed on the rotating rod 57 to limit the pushing block 55 to prevent the pushing block 55 from continuing to move forward due to erroneous rotation of the handle 52 after the pushing block 55 moves forward to the maximum position.

[0048] Furthermore, an annular groove 31 is formed in the middle of the grinding cylinder 32, and a rubber ring 33 is fixedly connected to the inner wall of the annular groove 31;

[0049] During operation, the rubber ring 33 is fixed in the annular groove 31 , and the polishing cylinder 32 can better clamp and fix the bottle body through the annular groove 31 .

[0050] Embodiment 2

[0051] See also Figure 4 As shown, comparative example 1 is another embodiment of the present invention, the bottom end of the moving block 21 is fixedly connected with a plastic baffle 23, and the plastic baffle 23 is made of transparent PP material;

[0052] During operation, the plastic baffle 23 is fixed at the bottom end of the moving block 21, and blocks the front of the blade 30 when the blade 30 rotates to avoid accidental contact with the blade 30. The plastic baffle 23 is made of transparent PP material, which makes it convenient to observe the removal of burrs on the bottle mouth by the grinding head 29 through the plastic baffle 23. When the blade 30 cuts off excess material on the bottle mouth, the plastic baffle 23 can also play a certain shielding role.

[0053] A method for removing burrs from a corrosion-resistant PET bottle in all directions, the method comprising the following steps:

[0054] S1. Place the PET bottle between the two groups of clamping blocks 51 and fix it by clamping the clamping blocks 51. Turn the handle 52. The push block 55 threadedly connected to the rotating rod 57 will move backward. The push block 55 pushes the two groups of push rods 53 to move. The two groups of clamping blocks 51 move away from each other. At this time, place the PET bottle between the two groups of clamping blocks 51. Then turn the handle 52 in the opposite direction. The two groups of clamping blocks 51 move closer to each other to fix the PET bottle.

[0055] S2, start the cylinder 28, let the grinding head 29 extend into the bottle mouth to remove the burrs on the bottle mouth, and the two sets of grinding cylinders 32 will approach each other and clamp the bottle body to facilitate the subsequent removal of the burrs on the bottle body;

[0056] S3. After the servo motor 48 is started, the rotating disk 44 rotates, and the grinding block 60 reciprocates on the bottom of the bottle to remove the burrs on the bottom of the bottle.
