Description

Technical Field

[0001] This utility model relates to the technical field of limiting mechanisms on capping machines, and in particular to a mechanism for controlling the capping machine to dispense caps when there are no bottles. Background Technology

[0002] The capping machine is equipped with a bottle body turntable and a cap turntable. In order to control the matching of the bottle body and the cap, a photoelectric system is installed on the cap conveyor line. When the photoelectric system detects the bottle body, it inputs the cap onto the cap turntable.

[0003] However, photoelectric detection systems have certain limitations. When there are obstructions between the photoelectric detection unit and the bottle rotating plate, or when the bottle height is too low, the photoelectric detection system cannot detect the bottle, resulting in the bottle cap not appearing after the bottle is dispensed. This prevents the capping machine from performing the capping operation in a timely manner, thus affecting the working efficiency of the capping machine. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mechanism for controlling the capping machine to not dispense caps when there are no bottles, which can avoid the phenomenon of the bottle body being dispensed but not dispensed, and improve the working efficiency of the capping machine.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A mechanism for controlling a capping machine to dispense caps when there are no bottles includes a mechanism body, the mechanism body including a first arc-shaped rod and a second arc-shaped rod, the first arc-shaped rod being rotatably mounted on a frame;

[0007] The first end of the first arc-shaped rod is close to the turntable on which the bottle is placed, and the first end of the first arc-shaped rod is located between the turntable and the frame;

[0008] A first connecting rod is provided on the side of the first arc-shaped rod away from the turntable. Both ends of the first connecting rod are fixed to the first arc-shaped rod, and the first connecting rod and the first arc-shaped rod together form a moving space.

[0009] The second arc-shaped rod is also rotatably mounted on the frame, and the tail end of the second arc-shaped rod is located within the moving space, and the cross-sectional width of the tail end of the second arc-shaped rod is adapted to the cross-sectional width of the inner hole of the moving space;

[0010] The first end of the second arc-shaped rod is near the bottle cap outlet;

[0011] When the first arc-shaped rod moves away from the turntable, it drives the second arc-shaped rod to move and moves the first end of the second arc-shaped rod away from the bottle cap outlet.

[0012] In a preferred embodiment, the present invention can be further configured such that the first arc-shaped rod is placed horizontally;

[0013] The second arc-shaped rod is placed vertically.

[0014] In a preferred embodiment, the present invention can be further configured as follows: the first arc-shaped rod bends away from the turntable, a first sleeve is fixedly provided at the bend in the middle of the first arc-shaped rod, a first fixing rod is provided on the frame, the first fixing rod passes through the first sleeve, and the first fixing rod is rotatably connected to the first sleeve.

[0015] In a preferred embodiment, the present invention can be further configured as follows: the second arc-shaped rod bends toward the turntable, a second sleeve is fixedly provided at the bend in the middle of the second arc-shaped rod, a second fixing rod is provided on the frame, the second fixing rod passes through the second sleeve, and the second fixing rod is rotatably connected to the second sleeve.

[0016] In a preferred embodiment, the present invention can be further configured such that the first end of the second arc-shaped rod is bent toward the bottle cap outlet, and the bottle cap is located at the bent end of the second arc-shaped rod.

[0017] In a preferred embodiment, the present invention can be further configured such that: an elastic part is connected between the tail end of the first arc-shaped rod and the frame, the first arc-shaped rod is located between the elastic part and the turntable, and the elastic part is a spring.

[0018] In a preferred embodiment, this utility model can be further configured as follows: a limiting rod is provided near the first sleeve, one end of the limiting rod is fixed to the frame, the limiting rod is in contact with one side of the first arc-shaped rod, the limiting rod is located between the spring and the first fixed rod, and the limiting rod keeps the spring in an elastic tension state at all times.

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] 1. By setting up a mechanism body, when the bottle body touches the first arc-shaped rod, the first arc-shaped rod drives the second arc-shaped rod to move, so that the bottle cap moves to the bottle cap rotating plate, ensuring that one bottle body corresponds to one bottle cap, avoiding the phenomenon of the bottle body coming out but not coming out, and improving the working efficiency of the capping machine.

[0021] 2. By incorporating an elastic element, the first arc-shaped rod is ensured to return to its initial position promptly after its movement.

[0022] 3. By setting a limit rod on the frame, the initial position of the first arc-shaped rod is limited by the limit rod, thereby reducing the contact time between the first arc-shaped rod and the bottle body. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example:

[0028] Reference Figures 1-2 As shown, the present invention discloses a mechanism for controlling a capping machine to dispense caps when there are no bottles, comprising a mechanism body, the mechanism body including a first arc-shaped rod 11 and a second arc-shaped rod 12.

[0029] Both the first arc-shaped rod 11 and the second arc-shaped rod 12 are rotatably mounted on the machine frame. The first arc-shaped rod 11 is in a horizontal position, and the second arc-shaped rod 12 is in a vertical position.

[0030] The first arc-shaped rod 11 bends away from the turntable. A first sleeve 2 is fixedly installed at the bend in the middle of the first arc-shaped rod 11. A first fixing rod 21 is installed on the frame, passing through the first sleeve 2 and rotatably connected to it. An elastic part, which is a spring, is connected between the tail end of the first arc-shaped rod 11 and the frame. The first arc-shaped rod 11 is located between the spring and the turntable.

[0031] A limiting rod 4 is installed near the first sleeve 2, with one end of the limiting rod 4 fixed to the frame. The limiting rod 4 and the first fixed rod 21 are located on the same plate on the frame. The limiting rod 4 is in contact with one side of the first arc-shaped rod 11, and the limiting rod 4 is located between the spring and the first fixed rod 21, ensuring that the spring is always in an elastically stretched state. Under no external force, the head end of the first arc-shaped rod 11 is close to the turntable where the bottle is placed, and the head end of the first arc-shaped rod 11 is located between the turntable and the frame.

[0032] As the turntable rotates, it causes the bottles to move. One of the bottles touches the head of the first arc-shaped rod 11, causing the head of the first arc-shaped rod 11 to move away from the turntable. At the same time, the tail of the first arc-shaped rod 11 moves towards the turntable, disengaging from the limiting rod 4 and pulling the spring. It should be noted that the tail of the first arc-shaped rod 11 does not contact the bottle.

[0033] Once the bottle body disengages from the first arc-shaped rod 11, the first arc-shaped rod 11 returns to its initial position, and the first end of the first arc-shaped rod 11 is located between two adjacent bottle bodies.

[0034] The second arc-shaped rod 12 is also rotatably mounted on the frame. The second arc-shaped rod 12 bends towards the turntable, and a second sleeve 3 is fixedly mounted at the bend in the middle of the second arc-shaped rod 12. A second fixing rod 31 is mounted on the frame, passing through the second sleeve 3, and is rotatably connected to the second sleeve 3. The position of the second sleeve 3 is higher than that of the first sleeve 2.

[0035] A first connecting rod 13 is provided on the side of the first arc-shaped rod 11 away from the turntable. Both ends of the first connecting rod 13 are fixed to the first arc-shaped rod 11, and the first connecting rod 13 and the first arc-shaped rod 11 together form a moving space 14. The tail end of the second arc-shaped rod 12 is located within the moving space 14, and the cross-sectional width of the tail end of the second arc-shaped rod 12 is adapted to the cross-sectional width of the inner hole of the moving space 14. The head end of the second arc-shaped rod 12 is close to the bottle cap outlet.

[0036] When the first arc-shaped rod 11 moves toward the elastic part, the first arc-shaped rod 11 drives the second arc-shaped rod 12 to move and moves the first end of the second arc-shaped rod 12 away from the bottle cap outlet.

[0037] The first end of the second arc-shaped rod 12 bends toward the bottle cap outlet, and the bottle cap is located at the bend of the first end of the second arc-shaped rod 12.

[0038] The implementation principle of the above embodiments is as follows:

[0039] As the turntable rotates, it causes several bottles to move together. When one of the bottles approaches the head of the first arc-shaped rod 11, this bottle causes the first arc-shaped rod 11 to rotate around the first fixed rod 21. The tail end of the first arc-shaped rod 11 causes a spring to stretch.

[0040] As the first arc-shaped rod 11 moves, it drives the first connecting rod to move, and simultaneously drives the moving space 14 to move. As the moving space 14 moves, it drives the second arc-shaped rod 12 to move, causing the second arc-shaped rod 12 to move away from the turntable and towards the first fixed rod 21.

[0041] The first end of the second arc-shaped rod 12 moves toward the turntable. The bottle cap at the bottle cap outlet moves onto the bottle cap turntable.

[0042] After the bottle passes the first end of the first arc-shaped rod 11, the first arc-shaped rod 11 returns to its initial position under the elastic restoring force of the spring, and the first arc-shaped rod 11 is located between this bottle and the adjacent bottle.

[0043] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
