In this embodiment, the obliquely arranged conveying belt 13 penetrates through the notch structure 1211, and the conveying plane of the conveying belt 13 is flush with the inner side surface of the back plate 1211, so that the packaging bottle caps 15 originally attached to the back plate 1211 can be directly transferred to the conveying plane of the conveying belt 13 passing through the hopper 12 along the inner side surface of the back plate 1211, and the packaging bottle caps 15 cannot be transferred due to the height difference.

In order to transfer the packaging caps 15 upward along with the obliquely arranged conveyor belt 13, the conveyor belt 13 of the present embodiment is provided with a plurality of material-carrying projections 131 at equal intervals on the surface thereof, so that part of the outer peripheral surface of the packaging caps 15 abuts against the top surfaces of the material-carrying projections 131 and is conveyed obliquely upward while being in close contact with the conveying surface of the conveyor belt 13. Here, the packing bottle cap 15 of the present embodiment has a circular plate 151 at one end and a circular ring 152 at the other end, as shown in fig. 3. And the inner peripheral surface of the ring 152 is provided with internal threads (not shown in the figures) which can be connected with the external threads of the bottle mouth of the packaging bottle 7. Therefore, when the packing bottle cap 15 can be abutted against the material carrying projection 131, three situations occur, the first situation is that the circular plate top surface 1511 of the circular plate 151 is directly attached to the conveying plane of the conveying belt 13, namely the outer peripheral edge of the circular plate 151 is directly supported on the top surface of the material carrying projection 131; in the second case, the outer peripheral surface of the ring 152 is supported on the top surface of the tape tab 131, and the circular plate 151 is exposed outside the tape tab 131; in the third case, the end face of the circular ring 152 is supported on the conveying plane of the conveyer belt 13, the outer circumferential surface of the circular plate 151 is supported on the top surface of the material loading projection 131, and the top surface 1511 of the circular plate faces outwards.

Because the end face of the circular plate 151 needs to be kept close to the conveying surface of the conveying belt 13 during the conveying process of the packaging bottle cap 15 in this embodiment, the top of the hopper 12 in this embodiment is provided with the limiting rod 14 parallel to the left edge of the conveying belt 13 to limit the packaging bottle cap 15 to move leftward, the lower part of the limiting rod 14 is provided with the first limiting plate 141 parallel to the surface of the conveying belt 13, and the upper part of the limiting rod 14 is provided with the second limiting plate 142 parallel to the surface of the conveying belt 13. Specifically, the inside hollow structure 143 that is equipped with of gag lever post 14 of this embodiment to hollow structure 143 middle part is equipped with the fixed column, and consequently first limiting plate 141 and second limiting plate 142 can be through the bolt and can dismantle with the fixed column and link to each other. Preferably, the end positions of the first and second limiting plates 141 and 142 may be provided with a slotted hole structure, so that the first and second limiting plates 141 and 142 can adaptively adjust the installation position with the fixed column and adjust the angle of swinging into the conveying belt 13.

In addition, the first limiting plate 141 and the second limiting plate 142 of the embodiment partially extend into the conveying direction of the conveyor belt 13 and are higher than the outer side surface of the material carrying projection 131, so that the first limiting plate 141 can push the ring 152 away from the material carrying projection 131 towards the packaging bottle caps 15 on the surface of the conveyor belt and directly fall back to the hopper 12, the second limiting plate 142 pushes the packaging bottle caps 15 to move rightwards and transfer to the top rail 161 of the material returning structure 16 arranged at the right side of the conveyor belt 13, and the lower end of the obliquely arranged top rail 161 is connected with the inlet end of the space conveying channel 18.

The packaging bottle cap conveying device 1 of the embodiment needs to ensure that the circular plate 151 of the packaging bottle cap 15 is in close contact with the surface of the conveying belt 13, so that when the packaging bottle cap 15 is conveyed along the inner space of the space conveying channel 18, the circular plate 151 of the packaging bottle cap 15 is in an upward state, and when the packaging bottle cap 15 is conveyed to the packaging bottle cap receiving and pushing device 5, the circular plate 151 of the packaging bottle cap 15 is still kept at an upper position, so that when the packaging bottle cap 15 and the packaging bottle 7 are connected up and down, the internal thread of the circular ring 152 is connected with the external thread of the opening of the packaging bottle 7 through.

Referring to fig. 6 to 11, for the above purpose, the packaging bottle cap transferring device 1 of the present embodiment is limited in terms of size, wherein the thickness of the circular plate 151 of the packaging bottle cap 15 is a1, the thickness of the circular ring 152 is a2, the vertical distance between the bottom surface 1512 of the circular plate and the surface of the conveying belt 13 is a3, the thickness of the outer side surface of the ribbon bump 131 perpendicular to the surface of the conveying belt 13 is b, the vertical distance between the inner side surface 1411 of the first limiting plate and the surface of the conveying belt 13 is c1, and the vertical distance between the inner side surface 1421 of the second limiting plate and the surface of the conveying belt 13 is. In order to ensure that the belt material projection 131 on the surface of the conveying belt 13 can smoothly pass through the first limiting plate 141 and the second limiting plate 142, the thickness b of the belt material projection 131 perpendicular to the surface of the conveying belt 13 needs to be smaller than the vertical distance c1 between the inner side surface 1411 of the first limiting plate and the surface of the conveying belt 13 and smaller than the vertical distance c2 between the inner side surface 1421 of the second limiting plate and the surface of the conveying belt 13.

In order to smoothly restrict the packing bottle caps 15, the top surface of which is attached to the surface of the conveyor belt 13, from the first stopper plate 141, the packing bottle caps 151 need to meet the condition (a1+ a2) ≦ c1, as shown in fig. 9.

In order to make the packing bottle cap 15 with the circular plate 151 facing outwards and the circular ring 152 facing inwards restricted by the first stopper plate 141, the present embodiment needs to define conditions a3 ≧ b > a2 and (b + a1) > c1, and when the above-mentioned conditions are met, the situation as shown in fig. 6 and 7 occurs, wherein as shown in fig. 6, the bottom 1512 of the circular plate is attached to the outer side surface of the material-carrying projection 131, and at this time, the circular plate 151 will interfere with the first stopper plate 141, so that the packing bottle cap 15 that does not meet the requirement of the placement position is pushed to the left and removed from the material-carrying projection 131; as shown in fig. 7, the bottom 1512 of the circular plate is spaced from the outer side of the material-carrying protrusion 131, and the circular plate 151 interferes with the first stopper plate 141, so that the unsatisfactory packing bottle cap 15 is pushed leftward and removed from the material-carrying protrusion 131.

It should be noted that, if b is limited to be less than or equal to a2, the ring 152 may attach to the conveyor belt 13, and this situation is also not in accordance with the limitation of the conveying form and position of the packaging bottle caps 15 in this embodiment (i.e. the requirement that the top surface of the circular plate 151 attaches to the surface of the conveyor belt 13), and it is also necessary to push the packaging bottle caps 15 out of the band material bumps 131 through the first limiting plate 141, obviously, this also causes the packaging bottle caps 15 attached to the conveyor belt 13 by the circular plate 151 to not pass through the first limiting plate 141 smoothly, so that the packaging bottle caps 15 attached to the conveyor belt 13 by the circular plate 151 can only pass through the condition that a3 is greater than or equal to b > a2, and thus the packaging bottle caps 15 can pass through the first limiting plate 141 smoothly as shown in fig.. The situation shown in fig. 6 and 7 can be primarily screened by the first limiting plate 141, and since the weight of the circular plate 151 of the packaging bottle cap 15 of the present embodiment is greater than the weight of the circular ring 152, the center of gravity of the packaging bottle cap 15 is far away from the conveying belt 13, the packaging bottle cap 15 in this situation cannot be reliably supported on the top of the material loading projection 131 for a long time during the conveying process, as shown in fig. 6 and 7. The packaging bottle cap 15 shown in fig. 8 still has certain defects, and the packaging bottle cap needs to be screened through a subsequent structure.

After being limited and screened by the first limiting plate 141, the packaging bottle caps 15 conveyed upwards by the obliquely arranged conveying belt 13 comprise the packaging bottle caps 15 (shown in fig. 9) with the circular plate 151 attached to the surface of the conveying belt and the packaging bottle caps 15 (shown in fig. 8) with the circular ring 152 attached to the surface of the conveying belt. In order to push the packaging bottle caps 15 on the surface of the conveyor 13 to the top rail 161 by the second stopper plate 142, the following relation (a1+ a2) ≧ c2 needs to be satisfied, and the above relation corresponds to the case that part of the packaging bottle caps 15 are exposed on the inner side surface 1421 of the second stopper plate, so that the packaging bottle caps 15 are pushed rightwards by the second stopper plate 142 and enter the top rail 161 to continue to roll downwards, as shown in fig. 10 and 11.
