Detailed implementation manners

[0018] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0019] Embodiments of the present invention: As Figures 1-4 shown, a feeding mechanism includes a base 1. A filter rod storage device, a feeding device and a discharging device are provided on the base 1. The bottom of the filter rod storage device has a filter rod outlet. The feeding device includes a pushing and pulling device and a feeding plate 2. The feeding plate 2 is installed on the pushing and pulling device. A feeding groove 3 is formed at the top of the feeding plate 2. The bottom surface of the filter rod storage device is slidably matched with the top surface of the feeding plate 2. The discharging device is arranged on one side of the feeding plate 2.

[0020] The pushing and pulling device extends and contracts at a fixed frequency, causing the feeding plate 2 to perform a reciprocating motion. The filter rods are stored in the filter rod storage device. The length of the feeding groove 3 at the top of the feeding plate 2 is equal to the length of a single filter rod, and the width of the feeding groove 3 is also equal to the diameter of a single filter rod. Therefore, when the feeding plate 2 makes a reciprocating motion, one filter rod falls into the feeding groove 3. When the feeding groove 3 moves to the position of the discharging device, the discharging device ejects the filter rod in the feeding groove 3, enabling the filter rod to enter the transmission device, realizing the stable and equally spaced conveyance of the filter rods.

[0021] Specifically, the filter rod storage device includes a support rod 4 and a storage box 5. The support rod 4 is arranged in the vertical direction. The lower end of the support rod 4 is fixedly connected to the top surface of the base 1. A connecting seat 6 is provided on one side of the storage box 5. The connecting seat 6 is fixedly connected to the top of the support rod 4, which can be fixedly connected by thread or by welding.

[0022] The storage bin 5 is used to store cigarette filters. The top of the storage bin 5 is open, which is convenient for the staff to add cigarette filters. A guide pipe 7 is provided downward at the bottom of the storage bin 5. The filter rod outlet is opened on the bottom surface of the guide pipe 7. The bottom surface of the guide pipe 7 is slidably matched with the top surface of the feeding plate 2. The length of the guide pipe 7 is adapted to the length of the cigarette filter rod, and the width of the guide pipe 7 is adapted to the diameter of the cigarette filter rod, so as to achieve the feeding effect of a single cigarette filter rod at a time.

[0023] Further, the pushing and pulling device includes a reciprocating cylinder 8 and a connecting rod 9. Two horizontally arranged connecting rods 9 are connected to the telescopic end of the reciprocating cylinder 8. An installation seat 10 is formed on the bottom surface of the feeding plate 2. The two connecting rods 9 are fixedly connected to the installation seat 10, and the connecting rod 9 is perpendicular to the feeding groove 3.

[0024] When the reciprocating cylinder 8 has two working positions, when the reciprocating cylinder 8 contracts, when the feeding groove 3 is aligned with the guide pipe 7, the reciprocating cylinder 8 stops contracting, and this is the first working position. Under the action of gravity, the filter rod falls into the feeding groove 3. Then the reciprocating cylinder 8 extends. When the feeding groove 3 is aligned with the discharging device, the reciprocating cylinder 8 stops extending, and this is the second working position. The discharging device pushes the filter rod out of the feeding groove 3.

[0025] Further, a sliding groove 11 is formed on the side wall of the feeding plate 2 facing the discharging device. The sliding groove 11 is communicated with the feeding groove 3, and an adapting arc port 12 is formed at the connecting position of the two. The sliding groove 11 is parallel to the connecting rod 9.

[0026] The discharging device includes a fixed seat 13, a discharging rod 14, a slider 15 and a spherical pushing block 16. The fixed seat 13 is fixedly arranged on the top of the base 1. A sliding hole 17 is provided at the upper end of the fixed seat 13, and the sliding hole 17 penetrates through the front and rear ends of the fixed seat 13. The discharging rod 14 is inserted and slidably matched with the sliding hole 17. The discharging rod 14 is horizontally arranged. The slider 15 is fixedly arranged at one end of the discharging rod 14. The spherical pushing block 16 is fixedly arranged on the slider 15. A limiting seat 18 is arranged at the other end of the discharging rod 14. An elastic component is also arranged on the discharging rod 14. The slider 15 is slidably matched with the sliding groove 11, and the adapting arc port 12 is used to accommodate the spherical pushing block 16.

[0027] Furthermore, the elastic component includes a spring 19, a pressing ring 20 and a contact disc 21. The spring 19 and the pressing ring 20 are both sleeved on the discharging rod 14. The contact disc 21 is threadedly connected to the discharging rod 14. The spring 19, the pressing ring 20 and the contact disc 21 are all located between the slider 15 and the fixed seat 13. One end of the spring 19 abuts against the side surface of the fixed seat 13, the other end of the spring 19 abuts against one end of the pressing ring 20, and the other end of the pressing ring 20 abuts against the contact disc 21.

[0028] By rotating the contact disc 21, the compression amount of the spring 19 can be adjusted, so as to adjust the pushing force when the spherical pushing block 16 falls into the adapting arc port 12.

[0029] Working principle of the present invention: First, the cigarette filter rod is placed into the storage bin 5. Under the action of gravity, the cigarette filter rod automatically slides downward, is automatically arranged through the material guiding pipe 7, and the reciprocating cylinder 8 operates. Through the connecting rod 9, the feeding plate 2 moves left and right reciprocally. During the moving process, when the position of the feeding groove 3 aligns with the bottom end of the material guiding pipe 7, the cigarette filter rod automatically slides into the feeding groove 3, and then follows the feeding plate 2 to move to the right. During the moving process, the slider 15 slides in the sliding groove 11, and at the same time, the spherical push block 16 is in sliding fit with the bottom of the sliding groove 11. When the position of the spherical push block 16 corresponds to the fitting arc opening 12, under the elastic force of the spring 19, the discharging rod 14 uses the spherical push block 16 to be stuck into the fitting arc opening 12, and the cigarette filter rod inside is pushed out. By repeating the above operations, an intermittent equal-period feeding effect is achieved, effectively solving the problems in the traditional technology that the filter rod feeding operation is uneven and it is impossible to achieve equal-period and uniform feeding of individual cigarette filter rods, which is beneficial to improving the processing efficiency and the forming effect of the cigarette filter rod.
