The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0046] like Figure 1-3 As shown, this embodiment provides a bottle conveying device, including a conveying mechanism, a bottle-pushing mechanism 1 and a bottle-guiding mechanism 2. The conveying mechanism can convey a material bottle 100; the bottle-pushing mechanism 1 includes a star wheel 11 and a guard plate 12. The star wheel 11 is rotatably arranged at one end of the conveying mechanism, and the guard plate 12 is arranged around the outer side of the star wheel 11. A bottle-pushing channel 13 is formed between the guard plate 12 and the star wheel 11. The star wheel 11 is provided with a plurality of bottle-pushing structures arranged in sequence along its circumference. The bottle-pushing structure can drive a material bottle 100 to move in the bottle-pushing channel 13; the bottle-guiding mechanism 2 includes two bottle-guiding structures 21. The two bottle-guiding structures 21 are respectively fixed on both sides of the conveying mechanism. A bottle-guiding channel 22 for the material bottle 100 to pass through is formed between the two bottle-guiding structures 21. The bottle-guiding channel 22 includes a straight channel 221 and a curved channel 222. One end of the curved channel 222 is connected to the straight channel 221, and the other end is connected to the bottle-pushing channel 13.

[0047] The bottle feeding device of this embodiment connects one end of the curved channel 222 to the straight channel 221 and the other end to the bottle shifting channel 13 formed between the star wheel 11 and the guard plate 12, so as to utilize the curved channel 222 to reduce the moving speed of the material bottle 100, thereby increasing the distance between two adjacent material bottles 100, avoiding the problem of the material bottle 100 being stuck when entering the bottle shifting channel 13, which is beneficial to reducing the maintenance cost of the bottle feeding device and improving production efficiency and product qualification rate.

[0048] It can be understood that the width of the bottle guide channel 22 is the distance between the two bottle guide structures 21 in the horizontal direction, and the width of the bottle guide channel 22 is slightly larger than the outer diameter of the material bottle 100. In other words, along the moving direction of the material bottle 100 in the bottle guide channel 22, multiple material bottles 100 are arranged in a row in the bottle guide channel 22, so that the two bottle guide structures 21 can protect the material bottles 100 to prevent the material bottles 100 from tipping over, and at the same time will not affect the movement of the material bottles 100.

[0049] In this embodiment, the bottle-pushing structure is a bottle-pushing groove 111 disposed on the outer periphery of the star wheel 11. When the material bottle 100 is located in the bottle-pushing groove 111, the guard plate 12 can prevent the material bottle 100 from escaping from the bottle-pushing groove 111, so that the material bottle 100 remains in the bottle-pushing groove 111 and moves in the bottle-pushing channel 13 along with the star wheel 11. The star wheel 11 has a pitch circle c. When the material bottle 100 is located in the bottle-pushing groove 111, the center lines of the material bottles 100 in the plurality of bottle-pushing grooves 111 are all located on the pitch circle c, that is, the center line of the bottle-pushing channel 13 is located on the circumference of the pitch circle c.

[0050] It should be noted that the structure and working principle of the star wheel 11 and the guard plate 12 are prior art and will not be described in detail here.

[0051] Furthermore, the conveying mechanism adopts a belt conveyor line in the prior art, or other mechanisms in the prior art that can convey the material bottle 100, which is not limited here.

[0052] In the present embodiment, the two bottle guide structures 21 have different lengths. Specifically, for the convenience of description, the two bottle guide structures 21 are respectively recorded as the first bottle guide structure and the second bottle guide structure, wherein the first bottle guide structure and the star wheel 11 are located on the same side of the center line of the bottle guide channel 22, and the second bottle guide structure and the guard plate 12 are located on the same side of the center line of the bottle guide channel 22, the guard plate 12 is connected to one end of the second bottle guide structure, the end of the second bottle guide structure facing away from the guard plate 12 is flush with the first bottle guide structure, and the end of the second bottle guide structure close to the guard plate 12 is longer than the first bottle guide structure. In this way, the material bottle 100 can be guided by the end of the second bottle guide structure close to the guard plate 12, so that the material bottle 100 can enter the bottle dialing channel 13; of course, in other embodiments, the lengths of the two bottle guide structures 21 can be set to be equal, and the length of the guard plate 12 can be increased, which can also guide the material bottle 100 and facilitate the material bottle 100 to enter the bottle dialing channel 13.

[0053] Optionally, one end of the center line of the curved channel 222 is tangent to the center line b of the straight channel 221 , so that the material bottle 100 can smoothly enter the curved channel 222 from the straight channel 221 .

[0054] Optionally, the other end of the center line of the curved channel 222 is tangent to the center line of the bottle-moving channel 13 , so that the material bottle 100 can smoothly enter the bottle-moving channel 13 from the curved channel 222 .

[0055] Optionally, the curved channel 222 includes a first curved channel and a second curved channel, one end of the first curved channel is connected to the straight channel 221; the center line a1 of the first curved channel is located on the circumference of the first preset circle 201; one end of the second curved channel is connected to the other end of the first curved channel, and the other end of the second curved channel is connected to the bottle-moving channel 13; the center line a2 of the second curved channel is located on the circumference of the second preset circle 202, and the second preset circle 202 is circumscribed with the first preset circle 201. Such an arrangement is conducive to ensuring that the material bottle 100 moves smoothly in the curved channel 222.

[0056] Optionally, the radius of the first preset circle 201 is equal to the radius of the second preset circle 202 , so that the moving speed of the material bottle 100 when moving in the curved channel 222 remains unchanged, so that the material bottle 100 can maintain balance and move smoothly.

[0057] Optionally, the bottle guiding structure 21 includes a support member 211 and a guide member 212 , and the support member 211 is fixed to one side of the conveying mechanism; in this embodiment, the guide member 212 is fixed to the support member 211 .

[0058] Optionally, there are multiple guide members 212; the multiple guide members 212 include a first guide member 2121 corresponding to the bottle neck of the material bottle 100; optionally, the multiple guide members 212 also include a bottle body guide member 212 corresponding to the bottle body of the material bottle 100. Such a configuration is equivalent to increasing the number of bottle protection layers, ensuring that the material bottle 100 moves more smoothly.

[0059] Optionally, a plurality of bottle body guide members 212 are provided, and the plurality of bottle body guide members 212 include a second guide member 2122 corresponding to the lower portion of the bottle body of the material bottle 100, and a third guide member 2123 corresponding to the middle portion of the bottle body of the material bottle 100. The second guide member 2122 and the third guide member 2123 are used to further increase the number of bottle protection layers, so that the material bottle 100 moves more smoothly.

[0060] Optionally, the multiple guide members 212 also include a fourth guide member 2124 arranged corresponding to the bottle mouth thread of the material bottle 100. The bottle mouth thread of the material bottle 100 is protected by the fourth guide member 2124 to avoid problems such as thread failure caused by bumps and further increase the number of bottle protection layers, so that the material bottle 100 moves more smoothly.

[0061] In this embodiment, the first guide member 2121 is fixedly mounted on the support member 211, and the fourth guide member 2124 is fixedly mounted on the first guide member 2121. It should be noted that in the existing material bottles 100, the spacing between the bottle neck and the bottle mouth thread of different types of material bottles 100 is basically the same, and the outer diameter of the bottle neck and the maximum outer diameter of the bottle mouth thread of the same type of material bottles 100 are basically the same, so the fourth guide member 2124 can be installed on the first guide member 2121, so as to facilitate the synchronous adjustment of the installation positions of the fourth guide member 2124 and the first guide member 2121, and the operation is convenient.

[0062] Optionally, a first height adjusting member 231 is provided between the fourth guide member 2124 and the first guide member 2121, and the first height adjusting member 231 is used to increase or decrease the height of the fourth guide member 2124. The height of the fourth guide member 2124 can be adjusted by the first height adjusting member 231, so as to adapt to material bottles 100 of different heights, thereby making the bottle feeding device more versatile.

[0063] Exemplarily, the first height adjustment member 231 includes a plurality of pads, and the purpose of increasing or decreasing the installation height of the fourth guide member 2124 can be achieved by increasing or decreasing the number of the pads. The structure is simple and easy to operate.

[0064] Optionally, for a material bottle 100 with a constant outer diameter of the bottle body, the third guide member 2123 can also be fixed to the second guide member 2122, and a second height adjusting member 232 can be provided between the third guide member 2123 and the second guide member 2122. The second height adjusting member 232 is used to increase or decrease the height of the third guide member 2123. The height of the third guide member 2123 can then be adjusted by the second height adjusting member 232, so as to adapt to material bottles 100 of different heights, thereby making the bottle feeding device more versatile.

[0065] Exemplarily, there are multiple second height adjustment members 232, and the heights of the multiple second height adjustment members 232 are different. Therefore, by replacing the second height adjustment members 232 of different heights, the purpose of increasing or decreasing the installation height of the third guide member 2123 can be achieved.

[0066] When the material bottle 100 moves in the straight channel 221, the probability of the material bottle 100 being bumped is small, while when the material bottle 100 moves in the curved channel 222, it needs to change the moving direction multiple times, which increases the probability of bumping. Optionally, the fourth guide member 2124 is provided in the curved channel 222, and the bottle mouth thread can be protected by the fourth guide member 2124, thereby improving the protection effect of the material bottle 100.

[0067] In other embodiments, it can also be configured that: the guide member 212 is adjustably disposed on the support member 211 along the width direction of the bottle guide channel 22. Specifically, the first guide member 2121, the second guide member 2122, the third guide member 2123 and the fourth guide member 2124 are all adjustably disposed on the support member 211 along the width direction of the bottle guide channel 22. By adjusting the installation position of the guide member 212 along the width direction of the bottle guide channel 22, the width of the bottle guide channel 22 can be changed, thereby adapting to material bottles 100 of different outer diameters, so that the bottle feeding device has stronger versatility.

[0068] Furthermore, the first guide member 2121 is height-adjustably disposed on the support member 211 , and thus the material bottles 100 of different heights can be adapted by adjusting the installation height of the first guide member 2121 , thereby making the bottle feeding device more versatile.

[0069] Furthermore, the second guide member 2122 is height-adjustably disposed on the support member 211 , and thus the material bottles 100 of different heights can be adapted by adjusting the installation height of the second guide member 2122 , thereby making the bottle feeding device more versatile.

[0070] Furthermore, the third guide member 2123 is height-adjustably disposed on the support member 211 , and thus the material bottles 100 of different heights can be adapted by adjusting the installation height of the third guide member 2123 , making the bottle feeding device more versatile.

[0071] Furthermore, the fourth guide member 2124 is height-adjustably disposed on the support member 211 , and thus the material bottles 100 of different heights can be adapted by adjusting the installation height of the fourth guide member 2124 , making the bottle feeding device more versatile.

[0072] Optionally, the bottle guide structure 21 also includes an installation component which is respectively arranged in correspondence with the first guide member 2121, the second guide member 2122, the third guide member 2123 and the fourth guide member 2124, and the installation component includes a bracket, a horizontal locking member and a height locking member. The bracket is movably arranged on the support member 211 along the width direction of the bottle guide channel 22, and the horizontal locking member is used to lock or unlock the first bracket with the support member 211. The first guide member 2121, the second guide member 2122, the third guide member 2123 and the fourth guide member 2124 are all movably arranged on the corresponding bracket along the height direction of the material bottle 100, and the height locking member is used to lock or unlock the first guide member 2121, the second guide member 2122, the third guide member 2123 or the fourth guide member 2124 with the corresponding bracket.

[0073] By unlocking the horizontal locking piece, the bracket can be moved along the width direction of the bottle guide channel 22, thereby driving the first guide member 2121, the second guide member 2122, the third guide member 2123 or the fourth guide member 2124 to move along the width direction of the bottle guide channel 22 until the first guide member 2121, the second guide member 2122, the third guide member 2123 or the fourth guide member 2124 is adjusted to a suitable position, and then the horizontal locking piece is locked to fix the bracket to the support member 211. Unlocking the height locking member can move the first guide member 2121, the second guide member 2122, the third guide member 2123 or the fourth guide member 2124 along the height direction of the material bottle 100 until the first guide member 2121, the second guide member 2122, the third guide member 2123 or the fourth guide member 2124 is adjusted to a suitable height, and then the height locking member is locked to fix the first guide member 2121, the second guide member 2122, the third guide member 2123 or the fourth guide member 2124 to the corresponding bracket. Such a setting has a simple structure and is convenient for adjusting the installation positions of the first guide member 2121, the second guide member 2122, the third guide member 2123 and the fourth guide member 2124, thereby achieving the purpose of matching different models of material bottles 100.

[0074] Exemplarily, the horizontal locking member includes a first bolt and a first nut, the support member 211 is provided with a first long hole, and the length direction of the first long hole is parallel to the width direction of the bottle guide channel 22, and the bracket is provided with a first round hole. Of course, in other embodiments, the first long hole can also be provided in the bracket, and the first round hole can be provided in the support member 211. The first bolt passes through the first long hole and the first round hole in sequence and is threadedly connected with the first nut. Loosening the first nut can enable the first bolt to move in the first long hole, and then the bracket can move along the length direction of the first long hole (i.e., the width direction of the bottle guide channel 22), and the structure is simple.

[0075] Exemplarily, the height locking member includes a second bolt and a second nut, the bracket is provided with a second long hole and the length direction of the second long hole is parallel to the height direction of the material bottle 100, the first guide member 2121, the second guide member 2122, the third guide member 2123 and the fourth guide member 2124 are all provided with a second round hole. Of course, in other embodiments, the first guide member 2121, the second guide member 2122, the third guide member 2123 and the fourth guide member 2124 can also be provided with a second long hole, and the first round hole is provided in the bracket.
