Embodiment
[0034] Referring to Figures 1-3 As shown in the figure, a novel cover hanging mechanism, comprising a cover hanging large plate 1, the cover hanging large plate 1 has a feeding channel 11 inside, the feeding channel 11 is in a square hole structure, and the size thereof only allows a single bottle cap to pass through in sequence, effectively avoiding the accumulation and blockage of bottle caps. One end of the cover hanging large plate 1 is stably arranged on a fixed plate 2, and the two are fixed through common and stable mechanical connection modes such as bolt connection and welding, a bottle cap inlet communicating with the feeding channel 11 is formed on the fixed plate 2, and it is ensured that the bottle cap can smoothly enter the feeding channel 11. The other end of the cover hanging large plate 1 is the bottle cap outlet of the feeding channel 11.
[0035] A pair of large plate supporting lugs 12 are arranged on the upper end face of the cover hanging large plate 1, and the large plate supporting lugs 12 are rotationally connected with one end of a pressing plate 3 through a pivot. In the embodiment, the above pivot connection mode is realized by a rotating shaft assembly 7 composed of a bolt 71 and a nut 72, and the pressing plate 3 can flexibly rotate around the bolt 71. The other end of the pressing plate 3 is exposed at the outlet of the feeding channel 11. When the bottle cap comes out of the outlet of the feeding channel 11, it will contact the pressing plate 3, and the pressing plate 3 realizes the downward pressing action by using its own gravity and the action of a pressing plate elastic assembly 4 arranged on the cover hanging large plate 1. The pressing plate elastic assembly 4 is used to limit the excessive upward overturning of the pressing plate 3 and provide assistance when the pressing plate 3 is pressed downward. In cooperation with the rotating shaft assembly 7, the frictional resistance between the pressing plate 3 and the upper plane of the bottle cap when the pressing plate 3 is lifted can be reduced.
[0036] Claw hand supporting lugs 13 are arranged on both sides of the cover hanging large plate 1, and one end of a claw hand 5 is also connected with the claw hand supporting lugs 13 through a pivot. In the embodiment, the above pivot connection mode is selected as a rotating shaft 8 pivot connection, and the claw hand 5 can flexibly rotate around the rotating shaft 8. The other end of the claw hand 5 is exposed at the outlet of the feeding channel 11, and the two claw hands 5 on both sides clamp the bottle cap. A claw hand elastic assembly 6 arranged on the cover hanging large plate 1 is used to limit the outward overturning of the claw hand 5. When the claw hand 5 clamps the bottle cap to perform the cover hanging action, the claw hand elastic assembly 6 can make the claw hand 5 maintain a suitable clamping force, and due to the pivot connection, the frictional force of the bottle cap on both sides during the cover hanging is reduced, so that the cover hanging process is more smooth.
[0037] The lower end of the hanging cover large plate 1 where the feeding channel outlet 11 is located is provided with a semicircular opening 14 to form a hanging cover channel. The semicircular opening 14 is matched with the shape of the bottle cap and can guide the bottle cap to accurately fall to the position to be hung. Of course, the hanging cover channel can also be a U-shaped opening or the like, as long as it can ensure smooth passage of the bottle cap and complete the hanging cover action.
[0038] In the embodiment, one end of the pressing plate 3 is provided with a lifting lug 31, and the lifting lug 31 is accurately machined with a through hole for the bolt 71 to pass through on the large plate lug 12, and the two are stably connected through a nut to ensure that the pressing plate 3 can flexibly rotate around the connection point. The other end (cover outlet end) of the pressing plate 3 is a bending part 32 with a circular arc transition, which is more in line with the contact with the upper end face of the bottle cap when in use. When the pressing plate 3 presses the bottle cap, the bending part 32 with smooth transition can effectively reduce the friction between the pressing plate 3 and the bottle cap, so that the cover is more smooth. Of course, the bolt and nut combination connecting the lifting lug 31 and the large plate lug 12 can also be replaced by a pin, a rivet or other connecting members that can realize fixed and rotatable connection.
[0039] In the embodiment, the hanging cover large plate 1 is provided with a boss 15, and the upper end face of the boss 15 is a plane. The pressing plate 3 is lapped on the boss 15, so that the pressing plate 3 is more stable during work. The pressing plate elastic assembly 4 is arranged on the hanging cover large plate 1 where the boss 15 is located. The specific structure of the pressing plate elastic assembly 4 is as follows:
[0040] The pressing plate elastic assembly 4 includes a first bolt 41, and a first through hole 33 is machined on the pressing plate 3 for the first bolt 41 to pass through. The lower end of the first bolt 41 is threadedly connected with the boss 15, so as to realize the detachable mounting of the first bolt 41 on the hanging cover large plate 1. The first bolt 41 is provided with a first spring 42 and a first nut 43. The first nut 43 is located on the first bolt 41 above the pressing plate 3, and the two ends of the first spring 42 are respectively abutted on the first nut 43 and the nut of the first bolt 41.
[0041] The position of the first nut 43 is adjusted in advance during use. When the pressing plate 3 is lifted, the first spring 42 is compressed to store elastic potential energy; when it is pressed down, the spring releases potential energy to assist the pressing plate 3 to act. Of course, the first bolt 41 can also be replaced by a screw rod, and the first spring 42 can also be replaced by elastic silica gel or the like, as long as it can realize the elastic control function of the pressing plate 3.
[0042] The third through hole vertically penetrating the claw hand supporting ear 13 is provided in the embodiment, the hole diameter is matched with the rotating shaft 8, and it is ensured that the rotating shaft 8 can smoothly pass through. The positioning hole arranged at one end of the claw hand 5 corresponds to the third through hole, and the two are pivotally connected through the rotating shaft 8. The rotating shaft 8 enables the claw hand 5 to flexibly rotate around it, realizing the action of clamping and loosening the bottle cap. Of course, the rotating shaft 8 described above can be replaced by a pin shaft, a hinged rod or the like, as long as the rotatable connection can be realized, the normal working demand of the claw hand can be met.
[0043] The claw hand elastic assembly 6 is composed of the second bolt 61, the second spring 62 and the second nut 63 in the embodiment. The second through hole penetrating the sidewall of the claw hand 5 is processed, and the second bolt 61 passes through the second through hole. The lower end of the second bolt 61 is threadedly connected with the cap hanging plate 1, realizing the stable installation of the assembly and the cap hanging plate 1. The second nut 63 is located outside the claw hand 5, and the pre-tightening force of the second spring 62 can be adjusted after being tightened. The second spring 62 is abutted against the second nut 63 and the nut of the second bolt 61 at two ends respectively, when the claw hand 5 is turned outwards, the second spring 62 is compressed, and the reverse force is generated to limit the turning. Of course, the second bolt 61 described above can be replaced by a screw rod, and the second spring 62 can be replaced by an elastic material such as elastic silica gel.
[0044] The rotating shaft assembly 7 is designed on the pressing plate 3, the resistance of the pressing plate 3 and the upper plane of the bottle cap when the bottle cap passes through is reduced. The rotating shaft 8 is increased at the claw hand 5, the claw hand 5 is installed on the rotating shaft 8, the pressure of the second spring 62 when the claw hand 5 is opened and closed is reduced, and then the resistance of the two side surfaces when the bottle cap passes through is reduced. The arc transition design is adopted at the cap outlet end of the pressing plate 3, when the lower cap operation is performed, the contact with the bottle cap is more smooth, and no additional resistance is generated. Due to the comprehensive reduction of the resistance of the two side surfaces, the upper plane of the bottle cap and the pressing plate, the cap passing capacity is significantly improved, the hanging cap process is more smooth, the cap falling or hanging deviation phenomenon can be effectively avoided, and the stability and accuracy of the hanging cap work are improved.
