Technical Field

[0002] In the process of food and pharmaceutical production, food or medicine needs to be filled into filling bottles, and then the filling bottles are sealed by the capping device. However, in the prior art, the filling bottles are usually placed at a fixed point, and then the capping head moves in the vertical direction and rotates during the feeding process to complete the capping operation, that is, the capping head only moves in the vertical direction, so the capping head needs to run a long track during the reciprocating movement, which leads to a low capping rate and is difficult to meet production needs.

[0003] Therefore, a filling bottle capping device is needed to solve the above problems. Utility Model Content

[0012] The lifting shaft is slidably installed inside the rotating sleeve along the vertical direction, and one end of the lifting shaft extends to the outside of the rotating sleeve and abuts against the two deflection blocks, and the other end is in close contact with the upper surface of the cam ring;

[0013] When the lifting shaft slides in the vertical direction, it can cooperate with the rotating shaft to control the two deflection blocks to switch between a closed state and an open state.

[0014] Furthermore, a positioning pin for limiting the position of the lifting shaft is arranged inside the rotating sleeve.

[0015] Furthermore, a compression spring is arranged between the outer wall of the lifting shaft and the lower surface of the rotating sleeve, so that the lifting shaft is always in close contact with the upper surface of the cam ring.

[0016] Furthermore, a roller is provided at the bottom of the lifting shaft.

[0017] Furthermore, one end of the lifting shaft abutting against the deflection block has a convex structure;

[0018] The lower surface of the deflection block is provided with a cavity matching the protruding structure;

[0035] By providing a bottle clamping mechanism including a rotating sleeve and a bottle clamping member and a cam ring, when the rotating sleeve rotates synchronously with the core shaft, the bottle clamping member can move in the vertical direction due to overlapping with the cam ring, thereby compensating for the feeding distance of the capping mechanism in the vertical direction, thereby shortening the trajectory of the capping mechanism that needs to move in the vertical direction, thereby achieving the purpose of saving process time and improving production speed.

[0036] In addition, since the bottle clamping member has a closed state and an open state and can be switched according to vertical movement, when the filling bottle is docked with the capping mechanism, the bottle clamping member can be in a closed state to ensure that the filling bottle is lifted and fixed at the same time, thereby improving the stability of the capping mechanism when the cap is screwed. When the filling bottle is separated from the capping mechanism, it can be in an open state to facilitate the subsequent process to transfer the capped filling bottle, so as to improve the continuity between the processes, thereby achieving the purpose of further improving the production rate.

[0045] The following will be described in more detail with reference to the schematic diagram of the present invention, wherein the preferred embodiment of the present invention is shown, and it should be understood that the present invention described herein can be modified by a person skilled in the art, while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to a person skilled in the art, and not as a limitation to the present invention.

[0046] 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. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0047] like Figures 1 to 3 As shown, the embodiment of the utility model provides a filling bottle capping device, including a mounting plate 1, a core shaft 2, a capping mechanism 3, a bottle clamping mechanism 4 and a cam ring 5.

[0048] One end of the core shaft 2 passes through the mounting plate 1 and is connected to the capping mechanism 3, and the other end is connected to a driving member 6. The driving member 6 drives the core shaft 2 to rotate, so as to synchronously drive the capping mechanism 3 and the bottle clamping mechanism 4 to rotate, and the steps of lifting and capping the filled bottle in the bottle clamping mechanism 4 are realized during the rotation process.

[0049] Specifically, the bottle clamping mechanism 4 includes a rotating sleeve 41 fixedly connected to the outer wall of the core shaft 2 and a plurality of bottle clamping members 42 annularly and equidistantly arranged on the rotating sleeve 41 .

[0050] Among them, the bottle clamping member 42 can move in the vertical direction and has a closed state and an open state, and switches between the open state and the closed state during the movement in the vertical direction to achieve clamping or loosening of the filled bottle. For example, when it is lifted to perform the capping operation, the filled bottle is in a clamping state to ensure the capping effect. When the capping is completed and the capped filled bottle is output to the next process, the capped filled bottle can be loosened to facilitate the docking or extraction of the subsequent process, such as docking through the discharge star wheel.

[0051] In addition, the cam ring 5 is fixedly mounted on the mounting plate 1, and the bottle clamping member 42 overlaps the upper surface of the cam ring 5, so that when the bottle clamping member 42 is synchronously rotated by the rotating power of the rotating sleeve 41, it moves in the vertical direction under the action of the cam ring 5. That is, the upper surface of the cam ring 5 is an annular curved surface with different heights, and the bottle clamping member 42 is lifted in the height direction while rotating through the height change, and the clamping or loosening of the filling bottle is completed during the lifting process, so the time required for the capping mechanism 3 to feed in the vertical direction is effectively saved, and the purpose of improving the production rate is achieved.

[0052] The device is provided with a bottle clamping mechanism 4 including a rotating sleeve 41 and a bottle clamping member 42 and a cam ring 5, so that when the rotating sleeve 41 rotates synchronously with the core shaft 2, the bottle clamping member 42 can move in the vertical direction due to overlapping with the cam ring 5, thereby compensating for the feeding distance of the capping mechanism 3 in the vertical direction, thereby shortening the trajectory of the capping mechanism 3 that needs to move in the vertical direction, thereby achieving the purpose of saving process time and improving production speed.

[0053] In addition, since the bottle clamping member 42 has a closed state and an open state and can be switched according to the vertical movement, when the filling bottle is docked with the capping mechanism 3, the bottle clamping member 42 can be in a closed state to ensure that the filling bottle is lifted and can also be kept fixed, thereby improving the stability of the capping mechanism 3 when the cap is screwed. When the filling bottle is separated from the capping mechanism 3, it can be in an open state, so that the subsequent process can transfer the capped filling bottle, so as to improve the continuity between the processes, thereby achieving the purpose of further improving the production rate.

[0054] like Figures 4 to 7 As shown, in this embodiment, a specific bottle clamping member 42 is provided to better drive the filling bottle to rise and fall while also being able to clamp or loosen the filling bottle.

[0055] Specifically, the bottle clamping member 42 includes two deflection blocks 421 and a lifting shaft 422 .

[0056] The two deflection blocks 421 are both rotatably mounted on the upper surface of the rotating sleeve 41 through a rotating shaft 7 with a return spring, and the rotating shaft 7 can move in the vertical direction. The deflection block 421 rotates around a certain point (i.e., the rotating shaft 7), thereby clamping or loosening the filling bottle, and because the rotating shaft 7 can move in the vertical direction, when the lifting shaft 422 lifts the deflection block 421, the filling bottle on the deflection block 421 can be lifted synchronously, so that when the capping mechanism 3 performs the capping operation, the distance moved in the vertical direction by the capping mechanism 3 can be effectively reduced, thereby achieving the purpose of improving the production and processing rate.

[0057] Specifically, the lifting shaft 422 is slidably installed inside the rotating sleeve 41 in the vertical direction, and one end extends to the outside of the rotating sleeve 41 and abuts against the two deflection blocks 421, and the other end is in close contact with the upper surface of the cam ring 5. Therefore, when the rotating sleeve 41 is rotated by the core shaft 2, the lifting shaft 422 moves along the annular curved surface on the upper surface of the cam ring 5 to complete the lifting function.

[0058] In addition, when the lifting shaft 422 slides in the vertical direction, it can cooperate with the rotating shaft 7 to control the two deflection blocks 421 to switch between a closed state and an open state.

[0059] It should be particularly noted that a positioning pin 411 for limiting the position of the lifting shaft 422 is disposed inside the rotating sleeve 41 , so that the lifting shaft 422 can only move in the vertical direction.

[0060] It should be particularly noted that a compression spring is provided between the outer wall of the lifting shaft 422 and the lower surface of the rotating sleeve 41 , so that the lifting shaft 422 is always in close contact with the upper surface of the cam ring 5 .

[0061] Wherein, a roller 8 is provided at the bottom of the lifting shaft 422 to reduce friction resistance.

[0062] In other embodiments, in order to facilitate the deflection block 421 to deflect when the lifting shaft 422 moves in the vertical direction, the connection between the lifting shaft 422 and the deflection block 421 is further limited.

[0063] Specifically, one end of the lifting shaft 422 that abuts against the deflection block 421 has a protruding structure 9 , and a cavity matching the protruding structure 9 is disposed on the lower surface of the deflection block 421 .

[0064] When the protruding structure 9 is completely wrapped by the cavity, the two deflection blocks 421 are in a closed state; when the protruding structure 9 gradually detaches from the cavity, the two deflection blocks 421 are in an open state; when the protruding structure 9 is completely detached from the cavity, the two deflection blocks 421 are in a closed state.

[0065] The protruding structure 9 includes a cylinder and a truncated cone symmetrically arranged at both ends of the cylinder, and the outer diameter of the truncated cone decreases in the direction away from the cylinder. Therefore, when the protruding structure 9 initially enters the cavity or separates from the cavity, the deflection block 421 rotates around the rotation axis 7 under the influence of the wedge surface of the truncated cone and the reset spring outside the rotation axis 7, so as to be in an open state. When the protruding structure 9 completely enters the cavity, under the action of the reset spring, the two deflection blocks 421 are reset and wrap around the protruding structure 9, so that the deflection blocks 421 are in a closed state at this time, so as to complete the clamping and limiting of the filling bottle.

[0066] like Figure 5 As shown, the cam ring 5 has a first smooth section and a second smooth section.

[0067] Among them, the first smooth section is higher than the second smooth section, and when the lifting shaft 422 is overlapped on the first smooth section, the protruding structure 9 is wrapped in the cavity (that is, the lifting shaft 422 rises to the highest point at this time); and when the lifting shaft 422 is overlapped on the second smooth section (that is, the lifting shaft 422 drops to the lowest point at this time), the protruding structure 9 is completely separated from the cavity.

[0068] It should be noted that when the lifting shaft 422 is in the connecting arc section between the first smooth section and the second smooth section, the protruding structure 9 is partially located in the cavity, so the deflection block 421 is in an open state, so that the capped filling bottle can be transferred to the next process (that is, transferred through the discharge star wheel), thereby achieving the purpose of improving the continuity between the processes.

[0069] In this embodiment, the capping mechanism 3 includes a capping drum 31 and a capping head 32 . The capping drum 31 is fixedly connected to the core shaft 2 . The capping head 32 is rotatably mounted on the lower surface of the capping drum 31 and matches the bottle clamping mechanism 4 .

[0070] The capping head 32 can rotate relative to the capping drum 31 and can be fed in a vertical direction while rotating. This is a prior art and will not be described in detail here.

[0071] In addition, a protective cover 10 is provided on the mounting plate 1, and the protective cover 10 is used to wrap the bottle clamping mechanism 4 and the cam ring 5, and the bottle clamping mechanism 4 can rotate relative to the protective cover 10 to avoid external factors from interfering with the internal structure and improve the stability of operation.

[0072] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
