Description

Technical Field

[0001] This utility model relates to the field of food and pharmaceutical packaging technology, specifically to a capping and sealing device. Background Technology

[0002] The cap and bottle are located at two positions on the same conveyor tray. The cap needs to be removed and then pressed or screwed onto the bottle to achieve capping or screwing. The capping process has a relative position requirement between the cap and the bottle. Currently, the screwing and capping processes are usually carried out separately at two stations, which takes up a large area and is costly. Moreover, the capping station only has vertical movement. When the relative position of the cap and the bottle does not meet the requirements, the cap angle cannot be adjusted, resulting in poor adaptability. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a capping and pressing device that reduces equipment space occupation, improves the production qualification rate, and has strong adaptability.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A capping and pressing device includes a positioning mechanism and a capping and pressing mechanism disposed above the positioning mechanism. The positioning mechanism is used to position the bottle body. The capping and pressing mechanism includes a cap-removing component, a lifting drive component, a moving drive component, and a rotating drive component. The lifting drive component is used to drive multiple cap-removing components to lift and lower. The moving drive component is used to drive the cap-removing components to move horizontally. The rotating drive component is used to drive the cap-removing components to rotate.

[0006] As a further improvement to the above technical solution:

[0007] The lifting drive assembly includes a lifting base, and the moving drive assembly includes a moving guide rail disposed on the lifting base and a first moving drive. The first moving drive is connected to the lid-removing assembly and is used to drive the lid-removing assembly to move on the moving guide rail.

[0008] Both ends of the lifting seat are provided with movable guide rails, and a first clearance channel for the lifting cover assembly to move is provided between the movable guide rails at both ends of the lifting seat.

[0009] The lifting drive assembly also includes a support frame, with lifting guide sleeves at both ends of the support frame. A lifting shaft is slidably disposed inside the lifting guide sleeve. One end of the lifting shaft is connected to the lifting drive, and the lifting seat is disposed at the other end of the lifting shaft. A clearance space is provided between the two lifting shafts for the conveyor to pass through.

[0010] The cap-removing assembly includes a mounting base slidably mounted on a moving guide rail. The mounting base is rotatably provided with a rotating shaft. One end of the rotating shaft is connected to a rotation drive assembly, and the other end is connected to a cap-removing pneumatic gripper.

[0011] The mounting base is provided with a fixed guide sleeve at the top, and the rotating shaft is sleeved in the fixed guide sleeve through a bearing.

[0012] The mounting base is provided with a buffer guide sleeve at the bottom, the cap-removing pneumatic gripper is slidably disposed in the buffer guide sleeve, and an elastic element is provided between the two. The cap-removing pneumatic gripper is connected to the rotating shaft by a spline.

[0013] The buffer guide sleeve is provided with a limiting part for restricting the movement of the cap-removing pneumatic gripper.

[0014] The rotary drive assembly includes a rotary drive mounted on a mounting base, and the rotary drive is connected to a rotary shaft via a transmission assembly.

[0015] The positioning mechanism includes a first positioning block, a second positioning block, and a second moving drive for moving the first positioning block and the second positioning block closer or further apart. The opposite ends of the first positioning block and the second positioning block are provided with positioning grooves for forming positioning channels. The first positioning block is also provided with a second clearance channel for the lifting and lowering of the cover assembly.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] The capping and pressing device disclosed in this utility model has a positioning mechanism that positions the input bottle. If the bottle needs to be capped, the moving drive component drives the cap-removing component to move to the cap-removing position to remove the cap, and then moves it above the bottle. Finally, the lifting drive component drives the cap-removing component to descend and press the cap onto the bottle opening. If the bottle needs to be screwed on, the rotating drive component can be used to drive the cap-removing component to rotate during descent.

[0018] This capping and pressing device can perform both screw capping and pressing capping, eliminating the need for separate operations at two workstations and reducing equipment space requirements. Furthermore, because the cap-taking component has a rotation function, the angle of the cap can be adjusted during pressing to ensure that the relative position of the cap and the bottle meets production requirements before the pressing action is performed, thereby improving the production qualification rate and making it highly adaptable.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Figures 1 to 8 An embodiment of the capping and pressing device of this utility model is shown. The capping and pressing device of this embodiment includes a positioning mechanism 1 and a capping and pressing mechanism 2 disposed above the positioning mechanism 1. The positioning mechanism 1 is used to position the bottle body 7. The capping and pressing mechanism 2 includes a cap-taking component 3, a lifting drive component 4, a moving drive component 5, and a rotating drive component 6. The lifting drive component 4 is used to drive the multiple cap-taking components 3 to lift and lower. The moving drive component 5 is used to drive the cap-taking components 3 to move horizontally. The rotating drive component 6 is used to drive the cap-taking components 3 to rotate.

[0033] In this capping and pressing device, the positioning mechanism 1 positions the input bottle 7. If the bottle 7 needs to be capped, the moving drive component 5 drives the cap-removing component 3 to move to the cap-removing position to remove the cap, and then moves it above the bottle 7. Finally, the lifting drive component 4 drives the cap-removing component 3 to descend and press the cap onto the bottle opening. If the bottle 7 needs to be screwed on, the rotating drive component 6 is used to drive the cap-removing component 3 to rotate during descent.

[0034] This capping and pressing device can realize both capping and pressing methods without having to be carried out at two separate workstations, reducing the space occupied by the equipment. Since the cap taking component 3 has a rotation function, the angle of the cap can be adjusted during the pressing process to ensure that the relative position of the cap and the bottle meets the production requirements before the pressing action is performed, thereby improving the production qualification rate and making it highly adaptable.

[0035] like Figure 2 , 3As shown in Figure 6, in this embodiment, the lifting drive assembly 4 includes a lifting base 41, and the moving drive assembly 5 includes a moving guide rail 51 disposed on the lifting base 41 and a first moving drive 52. The first moving drive 52 is connected to the cap-removing assembly 3 and is used to drive the cap-removing assembly 3 to move on the moving guide rail 51. The lifting base 41 drives the moving drive assembly 5 and the cap-removing assembly 3 to rise and fall, and the first moving drive 52 drives the cap-removing assembly 3 to move on the lifting base 41, thereby realizing the lifting and moving of the cap-removing assembly 3. The moving guide rail 51 provides guidance for the movement of the cap-removing assembly 3.

[0036] like Figure 5 As shown, in this embodiment, both ends of the lifting seat 41 are provided with movable guide rails 51, and a first clearance channel 42 for the lid-removing assembly 3 to move is provided between the movable guide rails 51 at both ends of the lifting seat 41. With movable guide rails 51 provided on both sides, the lid-removing assembly 3 slides on the movable guide rails 51 at both ends, which provides good guiding effect and strong support stability. In addition, the lifting seat 41 is provided with a first clearance channel 42 so that it will not interfere with the movement of the lid-removing assembly 3.

[0037] like Figure 5 As shown, in this embodiment, the lifting drive assembly 4 further includes a support frame 43. Lifting guide sleeves 44 are provided at both ends of the support frame 43. A lifting shaft 45 is slidably disposed within the lifting guide sleeves 44. One end of the lifting shaft 45 is connected to a lifting drive 46, and a lifting seat 41 is disposed at the other end of the lifting shaft 45. A clearance space 47 is provided between the two lifting shafts 45 for the conveyor tray 8 to pass through. The lifting drive 46 drives the lifting shaft 45 to move up and down within the lifting guide sleeves 44, thereby causing the lifting seat 41 to move up and down. The clearance space 47 allows the conveyor tray 8 to pass through, facilitating the application of a cover in conjunction with the cover-removing assembly 3.

[0038] like Figure 2 , 3 As shown in Figure 4, in this embodiment, the cap-removing assembly 3 includes a mounting base 31 slidably mounted on a moving guide rail 51. A rotating shaft 32 is rotatably mounted on the mounting base 31. One end of the rotating shaft 32 is connected to a rotating drive assembly 6, and the other end is connected to a cap-removing gripper 33. The mounting base 31 slides on the moving guide rail 51, driving the rotating shaft 32, the rotating drive assembly 6, and the cap-removing gripper 33 to move. The rotating drive assembly 6 drives the rotating shaft 32 to rotate, thereby driving the cap-removing gripper 33 to rotate, thus realizing the adjustment of the cap angle.

[0039] like Figure 6 As shown, in this embodiment, the top of the mounting base 31 is provided with a fixed guide sleeve 34, and the rotating shaft 32 is sleeved in the fixed guide sleeve 34 through the bearing 35.

[0040] like Figure 6As shown, in this embodiment, the mounting base 31 has a buffer guide sleeve 36 at its bottom, and the cap-removing gripper 33 slides in the buffer guide sleeve 36. An elastic element 37 is provided between the two. The cap-removing gripper 33 is connected to the rotating shaft 32 via a spline. When the lifting drive assembly 4 drives the cap-applying assembly 3 to descend and apply the cap, the cap-removing gripper 33 has a certain amount of room to move in the buffer guide sleeve 36. At the same time, the elastic element 37 provides a buffering effect for the cap-removing gripper 33. Since the other end of the rotating shaft 32 needs to be connected to the rotating drive assembly 6, a spline (not shown in the figure) is used to connect it to the cap-removing gripper 33. That is, the rotating shaft 32 and the cap-removing gripper 33 can move up and down relative to each other, but cannot rotate relative to each other. This satisfies the lifting space of the cap-removing gripper 33 without causing a large impact on the rotating shaft 32 and the rotating drive assembly 6.

[0041] like Figure 6 As shown, in this embodiment, the buffer guide sleeve 36 is provided with a limiting part 38 for restricting the movement of the cap-removing claw 33. This ensures that the movement of the cap-removing claw 33 is within a reasonable range.

[0042] like Figure 3 and 4 As shown, in this embodiment, the rotary drive assembly 6 includes a rotary drive 61 mounted on the mounting base 31, and the rotary drive 61 is connected to the rotary shaft 32 via a transmission assembly 62. The rotary drive 61 drives the rotary shaft 32 to rotate via the transmission assembly 62. Preferably, the transmission assembly 62 is a gear assembly.

[0043] like Figure 7 and 8 As shown, in this embodiment, the positioning mechanism 1 includes a first positioning block 11, a second positioning block 12, and a second moving drive 13 for moving the first positioning block 11 and the second positioning block 12 closer or further apart. The opposite ends of the first positioning block 11 and the second positioning block 12 are each provided with a positioning groove 15 for forming a positioning channel 14. The first positioning block 11 is also provided with a second clearance channel 111 for the cap-removing assembly 3 to pass through during lifting and lowering. The bottle body 7 is conveyed between the first positioning block 11 and the second positioning block 12, and then the second moving drive 13 drives the first positioning block 11 and the second positioning block 12 to move closer together, with their positioning grooves 15 forming a positioning channel 14, thus positioning the bottle body 7. Preferably, the conveying tray 8 conveys the bottle body 7 and the cap together, with the cap located on one side of the bottle body. Therefore, a second clearance channel 111 needs to be provided on the first positioning block 11 to provide clearance for the cap-removing assembly 3 to lift and lower to remove the cap.

[0044] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
