Abstract
Description
Technical Field
[0001] The present invention relates to the field of mechanical equipment, in particular to an explosion-proof bottle star wheel mechanism. Background Art
[0002] In the prior art, a star-wheel mechanism is typically combined with a curved guardrail to form a track for conveying materials. However, most prior art star-wheel mechanisms employ an integrated design. For details, see Chinese Patent Publication No. CN211870693U, which proposes a high-speed star-wheel positioning device. Its primary operating mechanism is to convey materials by gathering them through teeth and grooves. However, this integrated star-wheel mechanism suffers from the following technical drawbacks when conveying materials, such as bottles:
[0003] For example, if a bottle is blocked during conveyance or blocked by foreign objects before conveyance, causing a bottle jam, it will be squeezed against the star wheel mechanism, resulting in bottle explosions, breakage, cracks, and surface scratches. Furthermore, when the star wheel mechanism is running at high speed and an accident occurs, the drive motor cannot be stopped immediately, causing the bottle to be squeezed too hard and burst. The resulting bottle debris poses a significant health hazard to operators and also affects overall material production quality, efficiency, and costs.
[0004] Therefore, a kind of explosion-proof bottle star wheel mechanism is needed to solve the above-mentioned problem. Summary of the Invention
[0005] The purpose of the present invention is to provide an explosion-proof bottle star wheel mechanism, so that when the bottle body is stuck, the extrusion force formed between the star wheel mechanism and the bottle body can be buffered to prevent the bottle body from being damaged, thereby improving production quality and production efficiency and correspondingly reducing production costs.
[0006] In order to solve the above technical problems, the present invention provides an explosion-proof bottle star wheel mechanism, comprising a housing, a plurality of star wheel movable blocks and an annular elastic member;
[0007] The housing has a hollow chamber built into it;
[0008] The plurality of star wheel movable blocks are arranged in a ring shape and are hinged in the hollow cavity;
[0009] Two adjacent star wheel movable blocks are in contact with each other in sequence, and their side walls are exposed to the outside of the shell;
[0010] An arc-shaped hole is formed at the connection of two adjacent star wheel movable blocks;
[0011] The annular elastic member is arranged in the hollow chamber and is in synchronous contact with the plurality of the star wheel movable blocks;
[0012] When one of the star wheel movable blocks is squeezed by an external force, the star wheel movable block can deflect toward the center direction of the shell, and one end of the star wheel movable block shrinks into the hollow chamber, pushing the annular elastic member to deform;
[0013] When the star wheel movable block is not squeezed by external force, the annular elastic member is reset to push the star wheel movable block to reset, so that the arc-shaped hole is re-formed between two adjacent star wheel movable blocks.
[0014] Furthermore, the annular elastic member includes a plurality of annularly distributed fixing columns and an annular spring;
[0015] The plurality of fixing columns are disposed in the hollow chamber and are capable of self-rotation;
[0016] The annular spring is sleeved on the outside of the plurality of fixed columns and abuts against the star wheel movable block.
[0017] Furthermore, when the star wheel movable block is deflected by an external force, it deflects to between the two fixed columns.
[0018] Furthermore, an opening matching the fixing column is provided on the inner side of the star wheel movable block.
[0019] Furthermore, the star wheel movable block includes a rotating end and a deflecting end;
[0020] The rotating end is hinged to the housing, and the opening is provided on the rotating end;
[0021] The deflection end overlaps the adjacent rotation end in a clockwise or counterclockwise direction, and the deflection end abuts against the annular spring.
[0022] Furthermore, a roller is rotatably mounted on the end of the deflection end.
[0023] Furthermore, the arc-shaped hole includes a first arc-shaped groove and a second arc-shaped groove;
[0024] The first arc-shaped groove is provided on the rotating end;
[0025] The second arc-shaped slot is provided on the deflection end.
[0026] Furthermore, the housing includes an upper cover plate and a lower cover plate;
[0027] The upper cover plate is clamped with the lower cover plate.
[0028] Furthermore, the lower cover plate is provided with an arc track matching the star wheel movable block, so that the star wheel movable block deflects along a predetermined track when subjected to external force.
[0029] Furthermore, a positioning column matching the arc track is provided on the lower surface of the star wheel movable block.
[0030] Compared with the prior art, the present invention has at least the following beneficial effects:
[0031] By arranging a plurality of star wheel movable blocks and making the plurality of star wheel movable blocks surround each other to form a complete star wheel mechanism, and making a single star wheel movable block deflect toward the center direction of the shell, when the bottle body is stuck and squeezed by the star wheel movable block, the star wheel movable block deflects and contracts accordingly, forming a certain avoidance space to accommodate the bottle body, thereby reducing the squeezing force on the bottle body, and thus effectively preventing the bottle body from being scratched or bursting.
[0032] The annular elastic member allows the corresponding traction star wheel movable block to reset after a bottle jams, overlapping with the adjacent star wheel movable block and forming a corresponding arc hole to re-pull the bottle for conveyance. This effectively avoids bottle breakage caused by jamming and reduces surface scratches. This improves operational stability and safety, while also reducing the time and economic costs associated with bottle explosions, and improving efficiency and quality.

[0039] The following is a more detailed description of the explosion-proof bottle star wheel mechanism of the present invention, with reference to a schematic diagram, which illustrates a preferred embodiment of the present invention. It should be understood that those skilled in the art may modify the invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as a general guideline for those skilled in the art and not as a limitation of the present invention.
[0040] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are greatly simplified and not to exact scale, and are provided solely for the purpose of assisting in the description of the embodiments of the present invention.
[0041] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an explosion-proof bottle star wheel mechanism, which includes a housing 1 , a plurality of star wheel movable blocks 2 and an annular elastic member 3 .
[0042] The housing 1 has a built-in hollow chamber for accommodating the star wheel movable block 2 and the annular elastic member 3 .
[0043] Among them, multiple star-wheel movable blocks 2 are arranged in a ring shape and are all hinged in the hollow chamber, that is, when a single star-wheel movable block 2 is subjected to external force, the star-wheel movable block 2 is rotatably arranged circumferentially on the shell 1, the front end of the star-wheel movable block 2 is the rotating end 21, and the rear end of the star-wheel movable block 2 is the deflection end 22. The rotating end 21 is rotatably fixed on the shell 1, and the deflection end 22 of the star-wheel movable block 2 is overlapped clockwise or counterclockwise on the rotating end 21 of the adjacent star-wheel movable block 2, so that the star-wheel movable block 2 itself can deflect and swing with the rotation center of its own rotating end 21 as the fulcrum.
[0044] Two adjacent star wheel movable blocks 2 are in contact with each other in sequence, that is, a plurality of star wheel movable blocks 2 are connected in series to form a whole star wheel structure for conveying and delivering bottles.
[0045] In addition, the side walls of the star wheel movable blocks 2 are exposed to the outside of the shell 1 to ensure that each star wheel movable block 2 can contact the bottle body.
[0046] An arc-shaped hole 4 is formed at the connection between two adjacent star wheel movable blocks 2 for positioning the bottle body and completing the bottle body transportation through the track formed between the star wheel movable blocks and the guardrail plate.
[0047] The annular elastic member 3 is disposed in the hollow chamber and is in synchronous contact with the plurality of the star wheel movable blocks 2 , so as to provide elastic power to the star wheel movable blocks 2 .
[0048] See also Figure 3When one of the star-wheel movable blocks 2 is squeezed by an external force, the rotating end 21 can deflect toward the center of the housing 1, pulling the deflecting end 22 to retract into the hollow chamber and pushing the annular elastic member 3 to deform. In other words, when a bottle becomes stuck, the bottle will exert a squeezing force on the star-wheel movable block 2, which will then deflect under this squeezing force, creating a sufficient space between the star-wheel movable block 2 and the guardrail for bottle conveyance. This ensures that the bottle will not be subjected to the strong force between the star-wheel movable block 2 and the guardrail during a jam or blockage, ensuring that the bottle will not break or otherwise break.
[0049] In addition, when the star wheel movable block 2 is not squeezed by external force, the annular elastic member 3 is reset to push the deflection end 22 to overlap with the adjacent rotating end 21, so that the arc hole 4 is re-formed between the two adjacent star wheel movable blocks 2, that is, the bottle body is re-gathered into the arc hole 4 for subsequent feeding.
[0050] In summary, the device is provided with a plurality of star wheel movable blocks 2, and the plurality of star wheel movable blocks 2 are connected in series in sequence to form a complete star wheel mechanism. When a single star wheel movable block 2 is squeezed by an external force, its deflection end 22 can also be retracted into the interior of the shell 1 to form a larger space to accommodate the bottle body, thereby protecting the bottle body from being scratched or broken.
[0051] Furthermore, an annular elastic member 3 is provided to reset the star wheel movable blocks 2. When no external force is applied, the multiple star wheel movable blocks 2 re-form a complete star wheel mechanism, allowing bottles to be transported normally until the next bottle jam occurs. This device effectively prevents bottle breakage caused by bottle jams and reduces surface scratches. This improves operational stability and safety. It also reduces the time and economic costs associated with bottle explosions, improving efficiency and quality.
[0052] See also Figures 2 to 4 In this embodiment, a specific annular elastic member 3 is provided to provide reset power to the multiple star wheel movable blocks 2.
[0053] The annular elastic member 3 includes a plurality of annularly distributed fixing columns 31 and an annular spring 32 .
[0054] The plurality of fixing posts 31 are disposed in the hollow chamber and are capable of self-rotation. The annular spring 32 is sleeved on the outside of the plurality of fixing posts 31 and abuts against the planetary wheel movable block 2 .
[0055] By setting the fixing column 31, the annular spring 32 is positioned so that the annular spring 32 maintains an annular structure under normal conditions. Since the fixing column 31 can rotate, the friction resistance between the fixing column 31 and the annular spring 32 can be reduced accordingly.
[0056] Please continue reading Figure 3 When the star wheel movable block 2 is deflected by an external force, it deflects to between the two fixed columns 31 to prevent the deflected star wheel movable block 2 from colliding with the fixed columns 31 or forming corresponding interference.
[0057] In addition, an opening 211 matching the fixing post 31 is provided on the inner side of the rotating end 21 , forming an escape space to accommodate the fixing post 31 .
[0058] In this embodiment, the star wheel movable blocks 2 are further limited so that a plurality of star wheel movable blocks 2 can abut against the annular elastic member 3 synchronously.
[0059] The deflection end 22 abuts against the annular spring 32 , that is, the planetary wheel movable block 2 and the annular spring 32 are connected together through the deflection end 22 , so as to provide elastic force to the planetary wheel movable block 2 .
[0060] The deflection end 22 is rotatably mounted with a roller 221 for reducing frictional resistance formed when the annular spring 32 contacts the deflection end 22 .
[0061] In a further embodiment, in order to facilitate the installation of the star wheel movable block 2 and the annular elastic member 3, the housing 1 is further limited.
[0062] The housing 1 includes an upper cover plate 11 and a lower cover plate 12 ; the upper cover plate 11 is snap-connected with the lower cover plate 12 .
[0063] like Figure 5 and Figure 6 As shown, in order to make the star wheel movable block 2 deflect along a predetermined trajectory, it is ensured that it does not collide with the fixed column 31.
[0064] The lower cover plate 12 is provided with an arc track 121 matching the star wheel movable block 2, so that the star wheel movable block 2 deflects along a predetermined track when subjected to external force. The lower surface of the star wheel movable block 2 is provided with a positioning post 212 matching the arc track 121.
[0065] In order to form an arc-shaped hole 4 at the connection between the two star wheel movable blocks 2, the shape of the star wheel movable blocks 2 is further limited.
[0066] Specifically, the arc-shaped hole 4 includes a first arc-shaped groove 41 and a second arc-shaped groove 42 .
[0067] The first arc groove 41 is arranged on the rotating end 21 of the star wheel movable block 2; the second arc groove 42 is arranged on the deflection end 22 of the star wheel movable block 2, but when two adjacent star wheel movable blocks 2 are overlapped end to end, that is, when the rotating end 21 is connected to the deflection end 22, they can be combined to form a complete arc hole 4.
[0068] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
