Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-3 This utility model provides a technical solution: a cam-driven auxiliary feeding mechanism, including a feeding channel 1, a support 5 mounted on the bottom of the feeding channel 1 via a bracket, wherein the bracket includes a horizontal plate 3, the horizontal plate 3 is installed at the bottom of the feeding channel 1, a support plate 4 is mounted on the middle of the lower surface of the horizontal plate 3 via screws, the support 5 is mounted on the lower end of the support plate 4 via screws, a guide rail slider 15 is mounted on the lower surface of the support 5, a linear guide rail 14 is inserted into the guide rail slider 15, and a base 13 is provided on the lower side of the linear guide rail 14 and connected to the linear guide rail 14 via screws. The linear guide rail 14 and the guide rail slider 15 are connected to the linear guide rail 14. 5. The components work together to restrict the movement trajectory of the feed channel 1. The design uses a cylindrical cam 11 and a linear guide rail 14, which ensures smooth, reliable, and noiseless operation. The operation and maintenance are simple and cost-effective. The upper end of the support plate 4 is recessed downward to form an upper positioning groove. An upper protrusion that matches the upper positioning groove is installed in the middle of the lower surface of the horizontal plate 3. The upper protrusion is inserted into the upper positioning groove, which improves the stability of the assembly of the horizontal plate 3 and the support plate 4. A lower protrusion is installed at the lower end of the support plate 4. The upper surface of the support 5 is recessed downward to form a lower positioning groove. The lower protrusion is inserted into the lower positioning groove, which improves the stability of the assembly of the support plate 4 and the support 5.

[0024] See Figures 1-3A connecting rod 6 is rotatably mounted on one end of the support 5. An upper rocker arm 7 is rotatably mounted on the end of the connecting rod 6 away from the support 5. The upper rocker arm 7 is connected to a lower rocker arm 12 via a rocker arm bearing seat 8. A cylindrical cam 11 driven by a motor is slidably connected to the end of the lower rocker arm 12 away from the rocker arm bearing seat 8. A cam groove 10 is machined on the annular side of the cylindrical cam 11. A roller 9 is rotatably mounted on the end of the lower rocker arm 12 away from the rocker arm bearing seat 8, so that the roller 9 is positioned in the cam groove 10, thereby making the lower rocker arm 12 and the cam groove 10 interlock. Rolling contact is formed between the inner walls. A cylindrical cam 11 power output device is used. The feeding channel 1 operates in sequence with the pushing mechanism. The power is transmitted to the feeding channel 1 installed on the linear guide rail 14 through the connecting rod 6. This enables the feeding channel 1 to reciprocate back and forth and left and right to assist the product in the boxing action. Before the product is pushed into the box, the auxiliary feeding channel 1 first fits the box. Then the product passes through the channel and is guided into the box by the pushing rod. Since the channel fits in first and then the product is guided in, the success rate of product boxing is effectively improved.

Support ears 16 are installed on the two parallel sides of the feed channel 1, and the support ears 16 have openings that correspond to the slots 19. The notch 21 is matched so that the lower end of the screw 18 is screwed into the square nut 20 in the slot 19. At this time, the limiting post 2 is set on the upper side of the notch 21, the upper end of the screw 18 extends into the notch 21, the limiting post 2 is in contact with the feed channel 1, and the lower end of the limiting post 2 is in contact with the upper surface of the lug 16, thus completing the assembly of the feed channel 1 and the horizontal plate 3. The position of the screw 18 is adjusted along the strip groove 17. At this time, the relative position of the feed channel 1 and the horizontal plate 3 changes, thus realizing the fine adjustment of the position of the feed channel 1.
