[0036] Embodiment one

[0037] As shown in the accompanying Figure 1 and the accompanying Figure 2 , the present embodiment provides a double-row bottle feeding mechanism, which comprises a rack 1, a rotating disc 2 and a dial assembly 3 installed on the rack 1 through a bearing seat, and the bottle is fed to the clamping groove of the dial assembly. The rotating disc of the present embodiment is driven by a servo motor inside the rack, and the dial assembly and its installation method are not described here.

[0038] The rotating disc 2 and the dial assembly 3 of the double-row bottle feeding mechanism of the present embodiment are provided in parallel in two groups, which are arranged on both sides of the rack 1. The arrangement of the two groups of rotating discs and dial assemblies can double the production capacity. At the same time, the two groups of rotating discs and dial assemblies are independently controlled and operated. Even if one group has a problem, the other group can also operate independently, which can at least ensure that the operation does not stop production.

[0039] Further, the present embodiment is also designed with a transition plate 4, a center fence 5, a side fence 6 and a side baffle 7, wherein: the transition plate 4 is arranged on the rack 1 and is connected with the two rotating discs 2; specifically, the transition plate 4 of the present embodiment is arranged on the rack 1 through a support rod, and the transition plate 4 is provided with a avoiding hole for the rotation of the rotating disc, and the upper surface of the transition plate 4 is coplanar with the upper surface of the rotating disc 2; the center fence 5 is arranged on the transition plate 4 between the two rotating discs 2, the head part is designed as a tapered bottle separating part, and the two sides are designed as arc surfaces; two side fences 6 are arranged above the two rotating discs 2 and are fixedly installed on the rack 1 through a support, and the center position of the side fence 6 towards the rotating disc 2 is designed as an arc buffer area 6.1; two side baffles 7 are arranged on both sides of the transition plate 4, which are used for limiting the two sides of the bottle.

[0040] This embodiment uses two turntables corresponding to two dial wheel assemblies for bottle loading. The area enclosed by the central and side rails on the turntables is the bottle loading zone. Compared to the traditional channel-type bottle loading method, this significantly improves the bottle loading rate and facilitates higher dial wheel assembly speeds for extremely high production capacity. Testing shows that each set of dial wheels can achieve a production capacity of approximately 400 bottles / minute, and two sets can reach 800 bottles / minute.

[0041] Working principle: After cleaning, the bottles enter the bottle feeding mechanism from the mesh belt and flow to the turntables on both sides under the action of the central grid. The area between the central grid and the side grids serves as the bottle feeding area. As the turntable rotates, the bottles continuously enter the dial assembly. Excess bottles circulate in the arc-shaped buffer area of ​​the bottle feeding area to ensure that there is no bottle shortage during the operation of the dial assembly.

[0042] Example 2

[0043] The side baffle structure differs from that of Embodiment 1. (See attached diagram.) Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the side baffle 7 includes a fixed plate 7.1 and an elastic plate 7.2. The fixed plate 7.1 is fixedly installed on both sides of the bottle inlet end of the transition plate 4, and one end of the elastic plate 7.2 is fixedly installed on the fixed plate 7.1. To facilitate the smooth entry of bottles into the turntable, this embodiment provides an arc-shaped bottle-feeding area 6.2 near the bottle inlet side of the side railing 6, and the other end of the elastic plate 7.2 is arc-shaped and extends to the arc-shaped bottle-feeding area 6.2, so that the elastic plate and the side railing can transition in an arc shape, facilitating the entry of bottles into the turntable. In this embodiment, the side baffle is designed as an elastic structure, which can play a buffering role during the bottle entry process, allowing excess bottles to be squeezed to both sides.

[0044] Preferably, in this embodiment, the distance between the end of the elastic plate 7.2 away from the side baffle 7.1 and the arc-shaped bottle-reaming area is less than the outer diameter of the bottle, preventing the bottle from being squeezed out between the elastic plate and the side baffle. Furthermore, in this embodiment, an inner liner 7.3 made of polytetrafluoroethylene is also provided on the inner side of the elastic plate 7.2 to prevent the rough surface of the elastic plate from easily scratching the bottle surface.

[0045] Example 3

[0046] Based on Embodiment 2, this embodiment further includes a spring top rod 8, which is located on the side of the side rail 6 and its head abuts against the elastic plate 7.2 to provide support for the elastic plate.

[0047] Preferred options are listed below. Figure 4As shown, the spring ejector rod 8 of the embodiment comprises a fixed block 8.1, an ejector rod 8.2, a spring 8.3 and an adjusting nut 8.4, the fixed block 8.1 is installed on the side of the side fence 6, the ejector rod 8.2 is movably penetrated through the fixed block 8.1, the head of the ejector rod 8.2 abuts against the elastic plate 8.2, the spring 8.3 is arranged between the head of the ejector rod 8.2 and the fixed block 8.1, and the adjusting nut 8.4 is screwed on the tail of the ejector rod 8.2 for adjusting the length of the ejector rod extending out of the fixed block.

[0048] Embodiment Four

[0049] On the basis of the embodiment three, the embodiment further comprises a first proximity switch 9 and a second proximity switch 10, which are arranged in sequence behind the spring ejector rod 8 and are respectively used for detecting the tail length of the spring ejector rod, so as to realize the detection of the bottle shortage or bottle squeezing state. Specifically, the spring ejector rod 8, the first proximity switch 9 and the second proximity switch 10 of the embodiment are all fixedly installed on the side of the side fence through the channel steel, wherein the spring stop rod is installed in the groove of the channel steel, and the first proximity switch and the second proximity switch are installed in the waist-shaped groove of the channel steel.

[0050] Working principle: if the first proximity switch detects a signal, it means that the elastic plate is not squeezed, and the bottle quantity is insufficient, so the bottle quantity can be increased; if the second proximity switch detects a signal, it means that the elastic plate is squeezed too much, and the bottle squeezing phenomenon exists, so the bottle quantity needs to be reduced; if both the first proximity switch and the second proximity switch detect a signal, it means that the bottle quantity is appropriate. Therefore, the first proximity switch and the second proximity switch of the embodiment can realize the detection of the bottle shortage or bottle squeezing state.

[0051] Embodiment Five

[0052] On the basis of any one of the embodiments one to five, as shown in the accompanying drawings of Figure 1 , the accompanying drawings of Figure 2 and the accompanying drawings of Figure 5 , the side fence 6 of the embodiment comprises a fixed fence 6a and a movable fence 6b, the fixed fence 6a is fixedly installed on the support, and the movable fence 6b is rotatably installed on the support through a rotating shaft.

[0053] Preferably, the outer side of the end of the movable fence 6b away from the rotating disc 2 is provided with a spring 11, one end of the spring 11 is arranged in the mounting hole of the movable fence 6b, and the other end is arranged on the fixed plate 12 of the support.

[0054] Furthermore, in this embodiment, an adjusting bolt 13 is screwed onto the end of the movable barrier 6b furthest from the turntable 2, between the movable barrier 6b and the fixed barrier 6a, for adjusting the rotation angle of the movable barrier 6b. Specifically, the rotation angle of the movable barrier can be controlled by adjusting the length of the adjusting bolt.

[0055] As attached Figure 5 As shown, since the bottle may not be at the bottom of the slot in the dial assembly, the bottle may collide with the side rail and break when the dial rotates at a high speed. This embodiment addresses this by designing a movable rail that can open outwards when the bottle is squeezed against it, thus preventing the bottle from breaking.

[0056] Preferably, in this embodiment, a guide slope 6b.1 is provided on the side of the movable railing 6b adjacent to the dial assembly 3, and the guide slope 6b.1 and the arc-shaped buffer area 6.1 are provided with rounded corners, and multiple bearings 14 are rotatably installed on the rounded corners to further reduce the probability of bottle breakage.

[0057] Application example: A filling and capping machine is provided, which is equipped with a double-row bottle feeding mechanism as described in any one of embodiments one to five.

[0058] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
