Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, specifically to a cap-dropping mechanism for a filling machine. Background Technology

[0002] Based on our previously disclosed patented product, announcement number CN217972581U, its specific operation involves the bottle conveying assembly transporting bottles to below the cap outlet. Baffles on both sides of the outlet freely rotate to guide the caps as they fall, gathering them towards the bottle mouth. Then, a pressure plate above the outlet flattens the caps onto the bottle mouth. However, in practical application, it was found that because the pressure plate is directly fixed to the conveying pipe, when the cap passes the pressure plate, the plate cannot swing freely. As the cap is flattened by the pressure plate, it easily gets stuck between the pressure plate and the conveying pipe, preventing the caps from flowing smoothly out of the outlet and thus affecting the capping efficiency of the equipment. Utility Model Content

[0003] The purpose of this invention is to provide a cap-dropping mechanism for a filling machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cap-dropping mechanism for a filling machine, comprising a frame, a cap-screwing mechanism mounted on the frame, and an adjustment assembly mounted on the frame; the cap-screwing mechanism includes a support frame, on which a cap-screwing head and a support plate are also provided, and at the end of the support plate away from the support frame, a cap-hanging plate is also provided; the adjustment assembly includes a base; a pivot pin seat is provided on the base, and a pivot pin rod passes through a cap and connects to the pivot pin seat, so that one end of the cap rotates on the base; at the end of the cap away from the pivot pin seat, a pressure plate is also provided, and under the action of gravity, the pressure plate causes the bottle cap to flow horizontally between the cap-hanging plate and the pressure plate.

[0005] As a preferred technical solution of this utility model: the base is further provided with a top cover, and the top cover is further provided with a guide rod; the pressure cover is adapted to and connected to the guide rod through a provided guide hole.

[0006] As a preferred technical solution of this utility model: one side of the base is connected to a first baffle pin, and the other side of the base is connected to a second baffle pin.

[0007] As a preferred technical solution of this utility model: both the first baffle and the second baffle are provided with connecting rods, and are connected to the connecting rods through connecting parts, so as to cause the first baffle and the second baffle to move towards each other.

[0008] As a preferred technical solution of this utility model: one side of the base is connected to the first connecting plate via a support shaft, and the other side of the base is also connected to the second connecting plate via the support shaft; both the first connecting plate and the second connecting plate are connected to the crossbeam, and are connected to the frame via the columns on the crossbeam.

[0009] As a preferred technical solution of this utility model: the capping mechanism further includes a mounting plate, and the support plate is connected to the mounting plate through a slider.

[0010] As a preferred technical solution of this utility model: the mounting plate is further provided with a guide rod, and the slider is guided to slide by the guide rod.

[0011] The beneficial effects of this utility model by adopting the above technical solution are: 1. Since the pressure plate can rotate on the shaft pin seat, the pressure plate can smooth the bottle cap on the bottle mouth without affecting the smooth flow of the bottle cap, so as to solve the problem that the bottle cap is easily stuck in the prior art, which causes the bottle cap to not flow smoothly.

[0012] 2. Due to the force of gravity, the pressure plate flattens the bottle caps between the cap hanging plate and the pressure plate, ensuring that the caps are horizontally positioned on the bottle neck after moving to it. This solves the problem of the capping head not being able to tighten the caps smoothly when they are placed at an angle on the bottle neck. Based on this, the cooperation between the pressure plate and the cap hanging plate guides the bottle caps to fit horizontally on the bottle neck, thereby improving the capping efficiency of the equipment.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0019] Please see Figure 1-4 This utility model provides an embodiment of a cap-dropping mechanism for a filling machine, comprising a frame 1, a capping mechanism 2 mounted on the frame 1, and an adjustment assembly 3 mounted on the frame 1; the capping mechanism 2 includes a support frame 20, on which a capping head 21 and a support plate 25 are also provided, and at one end of the support plate 25 away from the support frame 20, a cap hanging plate 23 is also provided; the adjustment assembly 3 includes a base 35; the base 35 is provided with a pivot pin seat 314, and a pivot pin rod 310 passes through a capping cap 39 and connects to the pivot pin seat 314, so that one end of the capping cap 39 rotates on the base 35; at one end of the capping cap 39 away from the pivot pin seat 314, a pressure plate 312 is also provided, and under the action of gravity, the pressure plate 312 causes the bottle cap to flow horizontally from between the cap hanging plate 23 and the pressure plate 312.

[0020] In summary, since the pressure plate 312 can rotate on the shaft pin seat, reducing the resistance to the movement of the bottle cap, the pressure plate 312 can smooth the bottle cap on the bottle mouth without affecting the smooth flow of the bottle cap, thus solving the problem in the prior art that the bottle cap is easily stuck, causing the bottle cap to not flow smoothly.

[0021] At the same time, under the action of gravity, the pressure plate 312 causes the bottle cap to be flattened between the hanging plate 23 and the pressure plate 312, thereby ensuring that the bottle cap can be horizontally positioned on the bottle mouth after it is moved to the bottle mouth, so as to solve the problem that the capping head cannot tighten the bottle cap smoothly on the bottle mouth due to the bottle cap being placed at an angle on the bottle mouth.

[0022] Based on this, the pressure plate 312 and the cap hanging plate 23 are used to guide the bottle cap to fit horizontally on the bottle mouth, thereby improving the capping efficiency of the device.

[0023] Furthermore, the base 35 is also provided with a top cover 311, and the top cover 311 is also provided with a guide rod 38; the pressure cap 39 is adapted to be connected to the guide rod 38 through a guide hole 313. Therefore, by utilizing the closure of the top cover 311 and the base 35, the bottle cap can slide between the facing surfaces of the top cover 311 and the base 35. At the same time, the guide rod 38 guides the pressure cap 39 to slide in a directional manner, thus avoiding the problem that the pressure plate 312 on the pressure cap 39 cannot flatten the bottle cap due to the free movement of the pressure cap 39.

[0024] Furthermore, since one side of the base 35 is pin-connected to a first baffle 36 and the other side of the base 35 is pin-connected to a second baffle 37, specifically, both the first baffle 36 and the second baffle 37 are provided with connecting rods 315, and are connected to the connecting rods 315 through connectors to cause the first baffle 36 and the second baffle 37 to move towards each other. Therefore, when the two baffles move towards each other, the two clamps can be closed, thus allowing the two baffles to restrict the movement of the bottle cap from the side, ensuring that the bottle cap flows smoothly and directionally out of the cap opening. In particular, the mutual closing of the two baffles allows the device to accommodate bottle caps with smaller diameters.

[0025] Furthermore, since one side of the base 35 is connected to the first connecting plate 32 via a support shaft 34, and the other side of the base 35 is also connected to the second connecting plate 33 via the support shaft 34; both the first connecting plate 32 and the second connecting plate 33 are connected to the crossbeam 31, and are connected to the frame 1 via the column 30 on the crossbeam 31. Therefore, the adjustment assembly 3 can be easily and conveniently installed on the frame 1, while also providing a reliable working environment for the base 35.

[0026] Based on the above solution, since the capping mechanism 2 also includes a mounting plate 24, and the support plate 25 is connected to the mounting plate 24 via a slider 22, the position of the mounting plate 24 can be adjusted. Therefore, when the cap diameter decreases, the mounting plate 24 can be slid to ensure that the cap hanging plate 23 is always located below the pressure plate 312. By adjusting the position of the cap hanging plate 23 and the gap between the two baffles, the device can be adapted to caps of different diameters.

[0027] Furthermore, since the mounting plate 24 is also provided with a guide rod 26, and the slider 22 is guided to slide through the guide rod 26, it can be ensured that the mounting plate 24 will not rotate axially when sliding, so as to ensure that the cover plate 23 can slide horizontally below the pressure plate 312.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
