[0025] Embodiment

[0026] As Figure 1 shown. A plastic bottle cap cutting device includes an electrical box 1, and electrical components such as a controller and a motor are arranged inside the electrical box 1. A bottle cap feeding mechanism is arranged at one end of the top of the electrical box 1, and the feeding mechanism realizes the orderly arrangement of the bottle caps, facilitating the one-by-one cutting process of the bottle caps. A cutting mechanism for cutting the edge of the bottle cap is arranged at the other end of the top of the electrical box 1. The feeding mechanism and the cutting mechanism are connected by a conveying structure for adjusting the state of the bottle cap. The conveying structure can not only convey the bottle caps, but also rotate and adjust the state of the bottle caps during the conveying process, facilitating the bottle caps to enter the cutting mechanism.

[0027] As Figure 2 shown. The feeding mechanism includes a rotating plate 3, and the rotating plate 3 is rotatably connected to the top of the electrical box 1 through a bearing. A motor for driving the rotating plate 3 to rotate is fixedly arranged inside the electrical box 1. A protective cover 2 is arranged outside the rotating plate 3, and the protective cover 2 is coaxial with the rotating plate 3. The protective cover 2 is fixed on the upper surface of the electrical box 1. A fixed cover 4 coaxial with the rotating plate 3 is arranged above the rotating plate 3, and there is no contact between the fixed cover 4 and the rotating plate 3 to prevent the fixed cover 4 from interfering with the rotation of the rotating plate 3. The fixed cover 4 is connected to the protective cover 2 through a connecting plate 5, and the protective cover 2 supports the fixed cover 4 through the connecting plate 5. The fixed cover 4 protects the bottle caps on the rotating plate 3 to prevent the bottle caps from falling off the rotating plate 3 during the rotation with the rotating plate 3.

[0028] The fixed cover 4 is provided with a discharge port 7 through which the bottle caps pass. The width of the discharge port 7 is greater than the diameter of the bottle cap, and the height of the discharge port 7 is less than the diameter of the bottle cap and greater than the height of the bottle cap. In this way, only one bottle cap passes through the discharge port 7 each time, arranging the bottle caps. One side of the discharge port 7 is provided with a guide plate 8 that guides the bottle caps. The guide plate 8 is fixed to the fixed cover 4. A channel for the movement of the bottle caps is formed between the protective cover 2 and the fixed cover 4, and the width of this channel is slightly greater than the diameter of the bottle cap. A protective rod 6 for protecting the bottle caps is fixedly arranged on the connecting plate 5. The protective rod 6 protects above the bottle caps to prevent the bottle caps from falling off through the protective cover 2 during the movement and can keep the state of the bottle caps to prevent the bottle caps from turning upwards or standing upright.

[0029] The protective cover 2 is provided with a material conveying pipe 9 for conveying the bottle caps. One side of one end of the material conveying pipe 9 is connected to the protective cover 2, and the other side of one end of the material conveying pipe 9 is connected to the fixed cover 4; that is, the material conveying pipe 9 is communicated with the channel between the fixed cover 4 and the protective cover 2, and the bottle caps are sent into the material conveying pipe 9 under the centrifugal force at the channel. The material conveying pipe 9 is located on the tangent line of the protective cover 2, and the material conveying pipe 9 has a certain downward inclination for the convenience of the movement of the bottle caps in the material conveying pipe 9. The other end of the material conveying pipe 9 is connected to the conveying structure, and the bottle caps slide into the conveying structure through the material conveying pipe 9.

[0030] As Figure 3 shown. The material conveying pipe 9 is provided with a leakage port 15 for screening the bottle caps. The leakage port 15 is of a W-shaped structure. An opening for the bottle caps to fall is provided on the side wall of the conveying pipe. A discharge pipe 10 is arranged below the leakage port 15. The discharge pipe 10 is fixed to the side wall of the electrical box 1. When the bottle caps on the material conveying pipe 9 slide past the leakage port 15, the bottle caps with the opening upwards can pass smoothly through the support in the middle of the leakage port 15; for the bottle caps with the opening downwards, since there is no support at the center of the bottle cap, the bottle caps fall from the leakage port 15; thus, the screening of the bottle caps is realized, and the bottle caps are adjusted to a unified state with the opening upwards.

[0031] Pour the bottle caps above the rotating plate 3. The rotating plate 3 rotates, and the bottle caps move towards the edge of the rotating plate 3 under the centrifugal force, so that the bottle caps slide into the channel between the protective cover 2 and the fixed cover 4 from the discharge port 7. The rotating plate 3 continues to drive the bottle caps to move in the channel. The bottle caps move along the channel into the material conveying pipe 9. After being screened by the leakage port 15, the bottle caps in the material conveying pipe 9 slide into the conveying structure through the material conveying pipe 9.

[0032] As Figure 4As shown in the figure. The cutting mechanism includes a positioning seat 16 fixedly arranged on the top of the electrical box 1. A V-shaped opening for positioning the bottle cap is arranged on the top of the positioning seat 16. A rectangular second connecting seat 17 is fixedly arranged at the feeding end of the positioning seat 16, and the second connecting seat 17 is located at the end of the conveying structure. The inclination angle of the second connecting seat 17 is the same as the inclined surface angle of the V-shaped opening. Here, the inclination angle of the second connecting seat 17 refers to the rotation angle of the second connecting seat 17 around its central axis in the vertical plane, that is, the two adjacent inner sides of the second connecting seat 17 are flush with the side surface of the V-shaped opening, which is convenient for tilting the bottle cap into the positioning seat 16. A positioning plate 18 for positioning the bottle cap is fixedly arranged at one end of the positioning seat 16 away from the second connecting seat 17, realizing the positioning and blocking of the bottle cap. The bottle cap in the conveying structure enters the positioning seat 16 through the second connecting seat 17. The bottom surface of the bottle cap is almost flush with the side surface of the V-shaped opening, and the opening of the bottle cap faces away from the cutting structure. The positioning seat 16 makes the bottle cap placed in an inclined state on the V-shaped opening, which is convenient for bringing the bottle cap into the cutting structure through the moving structure for cutting.

[0033] A cutting structure for making a cut in the bottle cap is arranged at one end of the positioning seat 16. The cutting structure includes a support platform 19. The fan-shaped support platform 19 is fixed on the upper surface of the electrical box 1. The upper surface of the support platform 19 is flush with the upper surface of the positioning seat 16. A fan-shaped transmission plate 20 is fixedly arranged on the support platform 19, and the transmission plate 20 is coaxially arranged with the support platform 19. Transmission grooves are evenly arranged on the side edge of the transmission plate 20, and the transmission grooves are adapted to the anti-slip lines arranged on the side wall of the bottle cap, so that when the bottle cap slides along the side edge of the transmission plate 20, the transmission grooves can drive the bottle cap to rotate, thereby cutting the bottle cap. A cutting knife 21 is fixed above the transmission plate 20, and the cutting knife 21 is coaxially arranged with the transmission plate 20. A pressing plate 22 for fixing the cutting knife 21 on the transmission plate 20 is arranged above the cutting knife 21. The pressing plate 22 fixes the cutting knife 21 on the transmission plate 20 through bolts, which is convenient for replacing the cutting knife 21.

[0034] As Figure 5 shown in the figure. A moving structure for driving the bottle cap to move is arranged above the cutting structure. The moving structure includes a turntable 23. The rotating shaft of the turntable 23 is rotatably connected with the support platform 19 through a bearing. The rotating shaft of the turntable 23 is also rotatably connected with the upper surface of the electrical box 1 through a bearing. A motor for driving the turntable 23 to rotate is arranged inside the electrical box 1. A plurality of fixing rods 26 are evenly arranged in a circumferential array on the edge of the turntable 23. In this embodiment, there are six fixing rods 26.

[0035] The fixed rod 26 is fixedly connected to the turntable 23 through the mounting plate 29 fixedly arranged at the top. The mounting plate 29 locks and fixes the fixed rod 26 on the turntable 23 through bolts. The bottom end of the fixed rod 26 is rotatably provided with a rotating head 28 through a bearing. The rotating head 28 is inserted into the inside of the bottle cap and drives the bottle cap to move. The diameter of the rotating head 28 is smaller than the inner diameter of the opening of the bottle cap. The turntable 23 drives the rotating head 28 to move, the rotating head 28 drives the bottle cap to move, and the rotating head 28 presses the bottle cap against the transmission plate 20, so as to drive the bottle cap to rotate self - by through the transmission plate 20, realizing the rotary cutting of the bottle cap. A baffle 27 for positioning the bottle cap is fixedly arranged above the rotating head 28. The distance between the baffle 27 and the support table 19 is slightly larger than the height of the bottle cap, improving the stability of the movement and cutting of the bottle cap.

[0036] At the discharge end of the notch structure, there is a blanking port 24 for discharging the cut bottle caps. The blanking port 24 is arranged on the electrical box 1. A protective plate 25 is fixedly arranged at the top edge of the blanking port 24 to prevent the bottle cap from rolling off the upper surface of the electrical box 1. When the fixed rod 26 drives the bottle cap to move to the blanking port 24, the bottle cap falls into the blanking port 24 under the action of gravity, and is thus discharged through the blanking port 24.

[0037] The conveying structure includes a number of rectangular mounting seats 12, and the mounting seats 12 are fixedly connected to each other through a number of connecting rods 13. The connecting rods 13 are used to support the bottle caps. The inner cavity of the mounting seat 12 can exactly accommodate one bottle cap, so that only relative sliding can occur between the bottle cap and the mounting seat 12, and no relative rotation can occur. The connecting rods 13 are fixedly connected to the first connecting seat 14 fixedly arranged at the end of the conveying pipe. The mounting seats 12 drive the connecting rods 13 to gradually rotate and tilt from the first connecting seat 14 to the second connecting seat 17. The bottle cap enters the mounting seat 12 with the opening facing upward. As the mounting seats 12 and the connecting rods 13 rotate, the bottle cap is driven to rotate, adjusting the state of the bottle cap so that the bottle cap enters the positioning seat 16 with the opening tilted to one side.

[0038] A photoelectric switch can be arranged on the second connecting seat 17 as required. The photoelectric switch is used to detect the presence or absence of the bottle cap, so as to control the start and stop of the motor. A control panel 11 is arranged on the electrical box 1. The control panel 11 is provided with buttons such as switches as required. Electrical components such as the photoelectric switch, the motor, and the control panel 11 are all electrically connected to the controller using existing technologies as required.

[0039] Therefore, by using the plastic bottle cap notch device described in the present utility model, the problem of the complex structure of the existing bottle cap notch device can be solved, and the efficient and rapid notching of the bottle cap can be realized.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions of the present utility model or make equivalent substitutions, and these modifications or equivalent substitutions cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present utility model.
