It should be understood that these examples are used to illustrate the present invention and are not limited to the scope of the present invention. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the unspecified implementation conditions are usually the conditions in conventional experiments.

[0046] See also Figure 1-3 , is a structural schematic diagram of an embodiment of the present invention, which provides a multi-row bottle cap packaging device, including a cap feeding mechanism 1, a cap putting mechanism 2 and a cap pressing and screwing mechanism 3 which are sequentially arranged along the transmission direction of a bottle feeding track 4, the cap feeding mechanism 1 includes a bracket 1-1, four cap dropping tracks 1-2 fixed on the bracket 1-1, and a sliding cover mechanism arranged at the entrance of the four cap dropping tracks 1-2. It should be understood that other numbers of cap dropping tracks 1-2 can be set. In this example, four cap dropping tracks 1-2 are taken as an example.

[0047] See also Figure 4-7The sliding cover mechanism includes a sliding cover plate 1-3, and a cover blocking device 1-4 and a gate device 1-5 corresponding to each cover falling track 1-2. The sliding cover plate 1-3 includes a sliding cover vertical plate 1-3a, a sliding cover horizontal plate 1-3b arranged on one side of the sliding cover vertical plate 1-3a in the thickness direction, and a cover sliding plate 1-3c arranged on the other side of the sliding cover vertical plate 1-3a in the thickness direction. The sliding cover horizontal plate 1-3b and the cover sliding plate 1-3c have a first inclination angle A with the horizontal direction to facilitate the forward sliding transmission of the bottle cap 5 under the action of gravity. The sliding cover vertical plate 1-3a has a second inclination angle B with the vertical direction to facilitate the formation of a sliding cover channel between the cover sliding plate 1-3c and the sliding cover vertical plate 1-3a. Four cover-dropping openings 1-3d corresponding to the four cover-dropping tracks 1-2 are provided on the cover sliding plate 1-3c. The size of the cover-dropping openings 1-3d is slightly larger than the bottle caps 5 so that the bottle caps 5 can fall into the cover-dropping tracks 1-2. The cover-blocking device 1-4 is provided at the end of the cover-dropping openings 1-3d to block the bottle caps 5 at the corresponding entrances of the cover-dropping tracks 1-2. The gate device 1-5 is used to open or close the corresponding cover-dropping openings 1-3d.

[0048] In this example, the cover blocking device 1-4 located at the end of the cover sliding plate 1-3c (i.e., the entrance of the fourth cover falling track) is a cover blocking strip 1-4c extending from the cover sliding plate 1-3c to the cover falling track 1-2, and other cover blocking devices 1-4 include a first driving member 1-4a, and a blocking rod 1-4b transmission-connected to the first driving member 1-4a, the first driving member 1-4a is installed at the upper end of the sliding cover cross plate 1-3b, the blocking rod 1-4b extends to the corresponding entrance end of the cover falling track 1-2, and the gate device 1-5 is installed at the lower end of the sliding cover cross plate 1-3b. In this example, the first driving member 1-4a adopts a cylinder.

[0049] The gate device 1-5 includes a second driving member 1-5a and a gate 1-5b drivingly connected to the second driving member 1-5a. The gate 1-5b is driven by the second driving member 1-5a to extend between the cover drop opening 1-3d and the corresponding entrance of the cover drop track 1-2. A gate avoidance opening 1-3e corresponding to the gate 1-5b is provided on the sliding cover cross plate 1-3b. The size of the cover drop opening 1-3d matches the gate 1-5b. The gate 1-5b is driven by the second driving member 1-5a to extend to the cover drop opening 1-3d to block the bottle cap 5 on the cover sliding plate 1-3c. In this example, the second driving member 1-5a adopts a cylinder.

[0050] See also Figure 5 When the first bottle cap 5 is transported to the fourth cap drop location, the blocking rods 1-4b of the cap blocking devices 1-4 at the first, second and third cap drop locations are retracted, and the gate devices 1-5 at the first, second and third cap drop locations push the gate 1-5b, which extends to allow the second bottle cap 5 to pass. When the first bottle cap 5 passes the third cap drop location, the blocking rod 1-4b of the cap blocking device 1-4 at the third cap drop location extends to block the incoming bottle cap 5 and prevent the second bottle cap 5 from passing the third cap drop location.

[0051] See also Figure 6 , when the second bottle cap 5 is transported to the third cap drop location, the blocking rod 1-4b of the second and second cap drop location blocking device 1-4 retracts, and the gate device 1-5 of the first and second cap drop location pushes the gate 1-5b, and the gate 1-5b extends to allow the third bottle cap 5 to pass. When the third bottle cap 5 passes the second cap drop location, the blocking rod 1-4b of the second cap drop location blocking device 1-4 extends to block the incoming bottle cap 5, preventing the third bottle cap 5 from passing the second cap drop location. The rest is analogous.

[0052] See also Figure 8-10 The capping mechanism 2 includes a capping assembly and a protective assembly arranged at the exit of the capping track 1-2. The capping assembly includes a butterfly compression spring 2-1 installed on the capping track cover plate 1-2a, and a capping pressure plate 2-2 arranged on the capping track cover plate 1-2a. One end of the capping pressure plate 2-2 is limited on the capping track cover plate 1-2a through a limiting member 2-3, and the other end of the capping pressure plate 2-2 extends forward in the transmission direction of the bottle feeding track 4. The butterfly compression spring 2-1 abuts against the capping pressure plate 2-2. The protective assembly includes a cap claw 2-4 fixed on both sides of the capping track 1-2 through a limiting rod 2-5, and a cap claw compression spring 2-7 arranged between the outer end 2-5 of the limiting rod and the cap claw 2-4. The cap claw 2-4 is located on one side of the capping pressure plate 2-2 and is provided with a cap claw ring 2-6. When the bottle cap 5 is sent to the capping claw ring 2-6, the two capping claw rings 2-6 hold the bottle cap 5 tightly, and when the bottle 6 on the bottle feeding track 4 moves forward, the bottle cap 5 is put on the bottle 6, and the bottle 6 with the bottle cap 5 continues to move forward, the capping claw 2-4 opens, and the capping pressing plate 2-2 presses the bottle cap 5 on the bottle 6, and the bottle cap 5 moves toward the direction of the cap pressing and screwing mechanism together with the bottle 6.

[0053] In this example, a compression spring mounting frame 2-8 is provided on the cover drop track cover plate 1-2a, and a butterfly compression spring 2-1 is installed on the compression spring mounting frame 2-8 via a fixed shaft 2-9. When the bottle cap 5 is put on the bottle 6, the pressure of the butterfly compression spring 2-1 on the cover pressing plate 2-2 stably puts the bottle cap 5 on the bottle mouth.

[0054] See also Figure 11-14 The capping and rotating mechanism 3 includes a column 3-1, a first mounting plate 3-2, a second mounting plate 3-3 and a third mounting plate 3-4 arranged from top to bottom along the height direction of the column 3-1, a capping driving member 3-5 arranged on the first mounting plate 3-1, a capping mechanism 3-6 transmission-connected to the capping driving member 3-5, a capping driving member 3-7 installed on the second mounting plate 3-3, and a capping mechanism 3-8 installed on the third mounting plate 3-4, and the capping mechanism 3-8 is transmission-connected to the capping driving member 3-7.

[0055] The capping mechanism 3-8 includes a bearing seat 3-8a, a rotating shaft 3-8j supported by the bearing seat 3-8a, a driven wheel 3-8b mounted on the rotating shaft 3-8j, and two rotating wheel arms 3-8c inserted in the driven wheel 3-8b and the rotating shaft 3-8j. The driven wheel 3-8b is transmission-connected to the capping drive member 3-7 (i.e., meshed with the gear 3-7a on the motor). The two rotating wheel arms 3-8c are symmetrically arranged. The rotating wheel arms 3-8c are rotatably arranged in the driven wheel 3-8b via a rotating pin 3-8f. A capping head 3-8d is provided at the lower end of the rotating wheel arm 3-8c, and the bottle cap 5 is clamped between the two capping heads 3-8d.

[0056] In this example, the capping head 3-8d is arranged on the rotary arm 3-8c via the capping head adjusting member 3-8e, and the capping head adjusting member 3-8e is threadedly connected to the rotary arm 3-8c, and the distance between the two capping heads 3-8d can be adjusted by the capping head adjusting member 3-8e.

[0057] The capping mechanism 3-6 includes a capping driving rod 3-6a which is transmission-connected to the capping driving member 3-5, a rotary die 3-6b arranged at the lower end of the capping driving rod 3-6a, and a capping head 3-6c arranged at the lower end of the rotary die 3-6b. The rotary die 3-6b passes through the rotating shaft 3-8j and is located between two rotary arms 3-8c. The rotary die 3-6b includes a first die portion 3-6b1 and a second die portion 3-6b2 which are arranged up and down. The outer diameter of the first die portion 3-6b1 is larger than that of the second die portion 3-6b2. A rotary wheel 3-8h is provided at the upper end of the rotary arm 3-8c. When the first die portion 3-6b1 contacts the rotary wheel 3-8h, the two rotary arms 3-8c rotate toward the rotary die 3-6b to make the capping head 3-8d hold the bottle cap 5 tightly, thereby tightening the bottle cap 5.

[0058] Two limit pins 3-8i are arranged in the rotating shaft 3-8j along the height direction of the rotary die 3-6b, and a limit slot 3-6b3 matching the two limit pins 3-8i is arranged on the rotary die 3-6b, and the limit of the rotary die 3-6b moving up and down is realized by the cooperation of the limit slot 3-6b3 and the two limit pins 3-8i. The bottle 6 with the cap reaches the position of the capping mechanism 3 and is blocked by the bottle blocking member. The capping head 3-6c is driven by the capping driving member 3-6a, and the capping head 3-6c presses the bottle cap 5 on the bottle mouth. As long as the cap is pressed, the capping head 3-8d is moved outwards through the capping head adjusting member 3-8c. When the rotary die 3-6b moves down, the two capping heads 3-8d will not hold the bottle cap 5 tightly. When the capping is required, the capping head 3-6c moves downward, the motor starts, the rotary wheel 3-8h gradually rotates the rotary arm 3-8c by an angle along the outer side of the rotary mold 3-6b, and a pair of capping heads 3-8d hold the bottle cap 5 tightly and screw the bottle cap 5 on the bottle mouth.
