[0004] However, the existing carrier generally has a certain weight, and during the driving process of the conveyor belt, the carrier and the liquid-filled bottles will be subjected to external forces such as the weight of the carrier and the weight of the liquid, which will easily cause the conveyor belt to be squeezed in the direction of gravity, and further cause the conveyor belt to deform in the vertical direction, affecting the transfer effect of the conveyor belt on the carrier and the liquid-filled bottles.

[0005] In addition, during the transfer process of the carrier and the liquid-filled bottles driven by the conveyor belt when the conveyor belt runs to the ring-shaped turning area thereof, the carrier and the liquid-filled bottles will generate a centrifugal force, which will cause the conveyor belt to be subjected to a force deviating from the running track direction (i.e. in the radial direction of the ring-shaped turning part of the conveyor belt), and further cause the conveyor belt to deform deviating from the running track direction, affecting the transfer effect of the conveyor belt on the carrier and the liquid-filled bottles.

DETAILED DESCRIPTION

[0031] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0033] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0034] Reference Figures 1 to 10The embodiment of the present application provides a circular conveying system suitable for a filling, capping and sealing machine, which is used for conveying liquid-filled bottles. The circular conveying system comprises a base 1, a supporting device 2, a conveying device 3 and a carrier device 4, wherein the supporting device 2 and the conveying device 3 are both installed on the base 1, the carrier device 4 is used for carrying the liquid-filled bottles, the supporting device 2 is used for supporting the carrier device 4 and the liquid-filled bottles carried thereon, and the conveying device 3 is used for driving the carrier device 4 and the liquid-filled bottles carried thereon to run.

[0035] Specifically, the supporting device 2 has a supporting surface 20; the conveying device 3 comprises a conveying belt 31 and a driving part 32 used for driving the conveying belt 31 to run; the carrier device 4 is connected with the conveying belt 31, and along the direction of gravity, the carrier device 4 is always supported on the supporting surface 20; along the direction perpendicular to the side wall of the conveying belt 31, the carrier device 4 is limitingly connected with the supporting device 2.

[0036] It can be understood that, along the direction of gravity, the carrier device 4 is always supported on the supporting surface 20, so that the supporting device 2 can always support the carrier device 4 and the liquid-filled bottles in the direction of gravity during the process that the conveying belt 31 drives the carrier device 4 and the liquid-filled bottles to run, thereby avoiding the deformation of the conveying belt 31 caused by the gravity of the carrier device 4 and the liquid-filled bottles, and further avoiding the deformation of the conveying belt 31 affecting the stable transportation of the carrier device 4 and the liquid-filled bottles.

[0037] Further, along the direction perpendicular to the side wall of the conveying belt 31, the carrier device 4 is limitingly connected with the supporting device 2, so that the supporting device 2 can limit the carrier device 4, avoid the carrier device 4 deviating from the running track under the action of centrifugal force when the conveying belt 31 drives the carrier device 4 to run to the circular arc area, and further avoid the deformation of the conveying belt 31 in the direction perpendicular to the side wall, thereby avoiding the deformation of the conveying belt 31 affecting the stable transportation of the carrier device 4 and the liquid-filled bottles.

[0038] Referring to Figures 1 to 7 The supporting device 2 further comprises two straight plates 21 and an arc connecting rod 22; wherein the two straight plates 21 are oppositely arranged and fixedly connected with the base 1; the two oppositely arranged end portions of the two straight plates 21 are connected through the arc connecting rod 22, and the arc connecting rod 22 is arranged at the end of the straight plate 21 away from the base 1, so as to form an empty area at the lower end of the arc connecting rod 22.

[0039] It is understandable that the support device 2 is connected by two opposite straight plates 21 and two arc connecting rods 22, so that the upper end surface of the support device 2 (i.e. the support surface 20) is in a closed structure, so as to ensure that the support device 2 can always support the carrier device 4 in the direction of gravity, and ensure the stable transfer of the carrier device 4 and the liquid filling bottle. The two ends of the straight plate 21 are connected by the arc connecting rod 22, and the lower end of the arc connecting rod 22 forms an empty area, which can not only support and limit the carrier device 4, but also reduce the interference of the support device 2 to the carrier device 4, so that the carrier device 4 can stably and flexibly pass through the area corresponding to the arc connecting rod 22.

[0040] It is worth noting that the upper end surface of the straight plate 21 and the upper end surface of the arc connecting rod 22 form the support surface 20, and the carrier device 4 runs along the support surface 20 under the driving action of the conveyor belt 31.

[0041] Further, the support device 2 further comprises an annular frame 23, and the straight plate 21 is fixedly connected with the base 1 through the annular frame 23; the outer wall surface of the straight plate 21 protrudes from the outer wall surface of the annular frame 23, so that a limiting groove 24 is formed between the straight plate 21 and the annular frame 23; the carrier device 4 locally abuts against the limiting groove 24, so as to further increase the stability of the carrier device 4, and facilitate the stable operation of the carrier device 4.

[0042] Referring to Figures 1 to 7 , the carrier device 4 comprises a connecting assembly 40 connected with the conveyor belt 31, and a first arc abutting portion 41, a second arc abutting portion 42, a third arc abutting portion 43 and a fourth arc abutting portion 44 installed on the connecting assembly 40, wherein the arc surface of the first arc abutting portion 41 abuts against the support surface 20; the arc surface of the second arc abutting portion 42 abuts against the outer side wall surface of the support device 2; the arc surface of the third arc abutting portion 43 abuts against the inner side wall surface of the support device 2; and the arc surface of the fourth arc abutting portion 44 abuts against at least part of the groove wall surface of the limiting groove 24.

[0043] Specifically, the connecting assembly 40 comprises a first connecting plate 401, and a second connecting plate 402 and a third connecting plate 403 connected to the upper end and the lower end of the first connecting plate 401 respectively, and the second connecting plate 402 and the third connecting plate 403 are both perpendicular to the first connecting plate 401 and extend in different directions from both sides of the first connecting plate 401 respectively, the first connecting plate 401 is connected with the conveyor belt 31, the first arc abutting portion 41 and the third arc abutting portion 43 are installed on the second connecting plate 402, the second arc abutting portion 42 is installed on one end of the first connecting plate 401 relatively close to the second connecting plate 402, and the fourth arc abutting portion 44 is installed on one end of the first connecting plate 401 relatively close to the third connecting plate 403 (specifically, the lower end of the first connecting plate 401).

[0044] It is understandable that the arc surface of the first arc abutment part 41 abuts against the support surface 20, thereby enabling the support of the carrier device 4 in the vertical direction, while the arc surface of the second arc abutment part 42 abuts against the outer side wall surface of the support device 2, the arc surface of the third arc abutment part 43 abuts against the inner side wall surface of the support device 2, thereby enabling the limiting connection of the carrier device 4 and the support device 2 in the direction perpendicular to the side wall of the conveying belt 31. While the fourth arc abutment part 44 abuts against the groove wall surface of the limiting groove 24, the support point of the lower end of the carrier device 4 is increased, thereby facilitating the maintenance of the first connecting plate 401 in the vertical state, avoiding the deformation of the conveying belt 31 caused by the inclination of the first connecting plate 401, and ensuring the stable operation of the carrier device 4 itself.

[0045] Further, in the direction perpendicular to the side wall of the support device 2 (i.e. the direction perpendicular to the side wall of the conveying belt 31), the projection of the abutment position of the second arc abutment part 42 and the support device 2 coincides with the projection of the abutment position of the third arc abutment part 43 and the support device 2. This arrangement enables the forces between the second arc abutment part 42 and the support device 2 and the forces between the third arc abutment part 43 and the support device 2 to cancel each other out, thereby making the force on the support device 2 more uniform and avoiding the deformation of the support device 2 affecting the operation of the carrier device 4.

[0046] Referring to Figures 5 to 7 , the first arc abutment part 41, the second arc abutment part 42, the third arc abutment part 43 and the fourth arc abutment part 44 are connected in rolling with respect to the support device 2, thereby reducing the friction between the carrier device 4 and the support device 2.

[0047] Specifically, the first arc abutment part 41 comprises a first mounting shaft 411 and a first ball 412. The first mounting shaft 411 is fixedly connected to the second connecting plate 402 of the connecting assembly 40, and the central axis of the first mounting shaft 411 is perpendicular to the support surface 20 of the support device 2. The first ball 412 is rotatably mounted on the first mounting shaft 411 and is used to abut against the support surface 20 of the support device 2.

[0048] Further, two first arc abutment parts 41 are arranged in the running direction to maintain the balance of the entire carrier device 4.

[0049] Specifically, the second arc abutment part 42 comprises a second mounting shaft 421 and a second ball 422. The second mounting shaft 421 is fixedly connected to the first connecting plate 401 of the connecting assembly 40, and the central axis of the second mounting shaft 421 is perpendicular to the side wall surface of the first connecting plate 401. The second ball 422 is rotatably mounted on the second mounting shaft 421 and is used to abut against the outer side wall of the support device 2.

[0050] Further, the second arc abutting portion 42 is provided with one, so that the carrier device 4 can pass through the arc segment of the support device 2 (i.e. the corresponding position of the arc connecting rod 22).

[0051] Specifically, the third arc abutting portion 43 comprises a third mounting shaft 431 and a first roller 432. The third mounting shaft 431 is fixedly connected with the second connecting plate 402 of the connecting assembly 40, and the central axis of the third mounting shaft 431 is perpendicular to the support surface 20 of the support device 2. The first roller 432 is rotatably mounted on the third mounting shaft 431 and is used to abut against the inner side wall of the support device 2.

[0052] Further, the third arc abutting portion 43 is provided with one, so that the carrier device 4 can pass through the arc segment of the support device 2 (i.e. the corresponding position of the arc connecting rod 22).

[0053] Specifically, the fourth arc abutting portion 44 comprises a fourth mounting shaft 441 and a second roller 442. The fourth mounting shaft 441 is fixedly connected with the first connecting plate 401 of the connecting assembly 40, and the fourth mounting shaft 441 is mounted on the lower end of the first connecting plate 401. The central axis of the fourth mounting shaft 441 is parallel to the side wall surface of the first connecting plate 401 (i.e. perpendicular to the end surface of the first connecting plate 401). The second roller 442 is rotatably mounted on the fourth mounting shaft 441 and is used to abut against the outer side wall of the support device 2 (specifically, the outer side wall of the annular frame 23, i.e. the groove wall of the limiting groove 24).

[0054] Further, the fourth arc abutting portion 44 is provided with two. It should be understood that the corresponding inner side of the support device 2 is not provided with an arc abutting portion, so the fourth arc abutting portion 44 can be provided with two to maintain the balance of the carrier device 4, while not affecting the operation of the carrier device 4.

[0055] It is not difficult to understand that in this way, the upper and lower ends of the carrier device 4 and the support device 2 are all abutted by arc abutting portions (the first arc abutting portion 41, the second arc abutting portion 42, the third arc abutting portion 43, and the fourth arc abutting portion 44). On the one hand, the support device 2 can be used to stably support the carrier, avoid the carrier from tilting away from the vertical direction, and avoid the deformation of the conveying belt 31, so that the carrier can always stably run along the preset track. On the other hand, the support device 2 and the carrier can not generate a large friction force, which is further conducive to the stable operation of the carrier.

[0056] Referring to Figures 4 to 9The carrier device 4 further comprises a bearing part 45; the bearing part 45 comprises a bottom plate 451, a placing seat 452 and a limiting sleeve 453; wherein the bottom plate 451 is detachably installed on the connecting assembly 40; the placing seat 452 is rotationally installed on the bottom plate 451, and the upper end of the placing seat 452 is provided with a placing groove 4521; the limiting sleeve 453 is detachably installed in the placing groove 4521, and the inner side wall of the limiting sleeve 453 is used for abutting against the outer side wall of the liquid filling bottle.

[0057] Specifically, the limiting sleeve 453 is connected with the placing groove 4521 through threads. It is not difficult to understand that liquid filling bottles of different specifications usually have different diameters, in order to ensure the limiting effect on different liquid filling bottles, limiting sleeves 453 suitable for different liquid filling bottles can be provided, and the limiting sleeve 453 is connected with the placing groove 4521 through threads, which is convenient for the disassembly and stable installation of the limiting sleeve 453.

[0058] Further, the bottom wall of the placing groove 4521 is provided with an anti-skid pad 5, which can be made of elastic rubber or elastic silica gel material to increase the friction force received by the liquid filling bottle.

[0059] Due to long-term use, the anti-skid pad 5 is easily tightly attached to the bottom wall of the placing groove 4521 under pressure, which makes it difficult to disassemble. In order to reduce the difficulty of disassembly, in this embodiment, the bottom wall of the placing groove 4521 is communicated with the outer wall surface of the placing seat 452 through a communication channel 6.

[0060] Further, the communication channel 6 is provided as a downwardly inclined straight channel.

[0061] It is not difficult to understand that when the anti-skid pad 5 needs to be disassembled, an auxiliary tool (such as a jack) can be used to penetrate the communication channel 6 or gas can be introduced into the communication channel 6, so as to push the anti-skid pad 5 away from the bottom wall of the placing groove 4521, facilitating the disassembly of the anti-skid pad 5.

[0062] Referring to Figures 1 to 10 Further comprising a positioning adjusting device 7; the positioning adjusting device 7 comprises a driving assembly 71, a rotating shaft 72, a swing rod 73, a positioning column 74 and a positioning groove 75; the driving assembly 71 is installed on the base 1 and drives the rotating shaft 72 to rotate; the rotating shaft 72 is rotationally installed at a predetermined position of the base 1 and is connected with the swing rod 73 to drive the swing rod 73 to swing; the positioning column 74 is installed on the swing rod 73, the positioning groove 75 is arranged on the carrier device 4, and the positioning column 74 can swing with the swing rod 73 and be clamped into the positioning groove 75, so that the carrier device 4 is positioned at the predetermined position of the base 1.

[0063] It should be understood that, during the process of driving the plurality of carrier devices 4 to run by the conveying belt 31, when the carrier device 4 is transferred to the preset position (such as the corresponding filling, capping and other workstations), there may be a certain error between the actual position where the carrier device 4 stops and the preset position. Therefore, in the embodiment, by setting the positioning adjusting device 7, the fine adjustment of the position of the carrier device 4 can be realized after the carrier device 4 stops, so that the carrier device 4 is located at the preset position, and the effect of filling the liquid filling bottle of the carrier device 4 and capping is ensured.

[0064] In addition, it should be understood that the positioning adjusting device 7 can only be adjusted within a certain range, that is, when the actual position deviates from the preset position relatively small, it is ensured that the positioning column 74 can be clamped into the positioning groove 75, and during the clamping process of the positioning groove 75, the carrier device 4 is driven to move from the actual position to the preset position, so that the adjustment can be realized. If the difference between the two is large, manual maintenance by the operator is required.

[0065] Referring to Figures 1 to 10 The conveying belt 31 is arranged between the support device 2 and the carrier device 4, that is, the outer side of the conveying belt 31 is limited by the first connecting plate 401, and the inner side is limited by the straight plate 21, so that the excessive deformation of the conveying belt 31 can be further prevented.

[0066] Referring to Figures 1 to 10 The protective cover 8 is fixedly connected with the base 1.

[0067] Specifically, the protective cover 8 is arranged outside the support device 2 and the conveying device 3, and a gap is formed between the lower end surface of the protective cover 8 and the base 1. The carrier device 4 comprises a connecting assembly 40, which is partially located in the protective cover 8 and partially extends from the lower end of the protective cover 8 (i.e. the gap position) to the periphery of the protective cover 8.

[0068] Specifically, the first connecting plate 401 and the second connecting plate 402 of the connecting assembly 40 are located in the protective cover 8, one end of the third connecting plate 403 is connected with the first connecting plate 401, and the other end extends to the outside of the protective cover 8 from the gap between the protective cover 8 and the base 1, and the carrying part 45 is installed in the area of the third connecting plate 403 located outside the protective cover 8.

[0069] The above-mentioned embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and substitutions made by those skilled in the art on the basis of the present application are within the scope of protection of the present application.
