Description

Technical Field

[0001] The utility model belongs to the technical field of automatic capping of disinfectants, and particularly relates to an automatic capping device for disinfectants. Background Art

[0002] A disinfectant is a reagent with disinfection and sterilization functions, mostly in liquid preparation. Disinfectants have very wide applications in the industry. By using disinfectants, viruses and bacteria in the room can be disinfected and killed to achieve a sterile state. Disinfectants such as sodium hypochlorite disinfectant are the most widely used in the industry. Specifically, the disinfection effect of sodium hypochlorite disinfectant is stronger than that of other types of disinfectants. Therefore, the demand for sodium hypochlorite type disinfectants in the consumer market is relatively large.

[0003] In the production process of disinfectants, the pre-prepared disinfectant is filled into the disinfectant bottle by a filling method, and then the bottle cap needs to be tightened onto the mouth of the disinfectant bottle. Specifically, the capping machine feeds the bottle caps onto the bottle mouths, and the disinfectant bottles with the untightened bottle caps enter the capping station for capping.

[0004] However, in the actual working process, the most conventional capping method at present is to use a liftable drive shaft to press against the top of the cap body and rely on friction to tighten the cap body. However, in the actual working process, a relatively large pressure is required to tighten the cap body. If the pressure is too large, it is easy to cause deformation of the cap body, and even the cap body is easily pressed and deformed during the capping process. After the cap body is deformed, its sealing performance is reduced.

[0005] At the same time, since the sizes of the bottle caps adapted to different models of bottles are often different, and the existing capping equipment can only tighten a single type or a few types of bottle caps, it simply cannot meet the diverse needs of product production in the workshop.

[0006] That is, in the actual production process, different types of products often match different bottle caps, and the difficulty of tightening them is also different. Therefore, how to use a single capping device to cap products of multiple specifications is very important for improving production efficiency and reducing production costs. Summary of the Utility Model

[0007] Based on the above background, the purpose of the utility model is to provide an automatic capping device for disinfectants.

[0008] To achieve the above purpose, the utility model adopts the following technical solutions:

[0009] An automatic capping device for disinfectants, including a capping mechanism, the capping mechanism includes a mounting frame, and two sides inside the mounting frame are respectively assembled and connected with mutually cooperating capping components;

[0010] The capping assembly includes a fixed seat, and a capping motor with two sides spaced apart is assembled and connected to the bottom of the fixed seat;

[0011] The capping motor is equipped with a capping shaft, and a capping sleeve is assembled and connected to the bottom of the capping shaft;

[0012] It is slidably connected between the fixed seats;

[0013] The capping mechanism further includes a cylinder mechanism that pushes the capping assemblies closer to each other and then caps the bottle;

[0014] The cylinder mechanism includes a pushing cylinder that respectively pushes the fixed seat. When capping, the capping assemblies are moved closer to each other until the rotating capping sleeve abuts against the bottle cap for capping;

[0015] The capping sleeve is detachably assembled on the capping shaft through a buckle structure. The buckle structure includes a buckle seat buckled at the bottom position of the capping shaft, and a rubber sleeve is sleeved on the buckle seat.

[0016] Preferably, the side walls of the fixed seats facing each other are slidably connected through slide bars spaced apart on the left and right sides.

[0017] Preferably, the longitudinal cross-sectional shape of the mounting frame is U-shaped, and the pushing cylinders are respectively fixedly assembled and connected to the lower ends of the front and rear side walls of the mounting frame;

[0018] The piston rod of the pushing cylinder is installed on the fixed seat.

[0019] Preferably, both ends of the side wall of the fixed seat are respectively fixedly connected with spring slide bars slidably connected to the mounting frame, and the spring slide bars are slidably connected to the mounting frame;

[0020] A spring is sleeved on the spring slide bar, and both ends of the spring are respectively fixedly connected to the side walls of the fixed seat and the mounting frame facing each other.

[0021] Preferably, the buckle structure further includes a lock buckle fixed seat fixedly connected to the bottom position of the capping shaft, and the lock buckle fixed seat and the buckle seat are locked through a plurality of elastic lock convex structures.

[0022] Preferably, the elastic lock convex structure includes an elastic lock convex elastically installed on the lock buckle fixed seat, and a spherical buckle groove for locking the elastic lock convex is provided on the inner side wall of the buckle seat;

[0023] The locking end of the elastic lock convex is a curved end, and a guiding chute communicating with the spherical buckle groove is provided on the inner side wall of the buckle seat;

[0024] During the buckling process, the elastic lock convex slides along the guiding chute and is limited to the spherical buckle groove.

[0025] Preferably, a sliding groove for slidably connecting the elastic locking protrusion is formed on the fixed seat, and an inner spring is fixedly connected in the sliding groove and is fixedly connected to the elastic locking protrusion.

[0026] Preferably, lid-straightening mechanisms are respectively installed on the front and rear side walls of the mounting bracket.

[0027] Preferably, each lid-straightening mechanism includes a mounting seat fixedly connected to the mounting bracket, and an elastic lid-straightening dial plate is fixedly connected to the mounting seat.

[0028] The utility model has the following beneficial effects:

[0029] 1. During the working process, since the cap screwing assemblies on the front and rear sides are both driven by cylinders, during the working process, for cap bodies of different sizes, under the drive of the cylinders, they can all be fully abutted and rubbed against the cap bodies, so as to process products of various specifications.

[0030] After screwing the cap, through the spring structure, under the cooperation of the elastic restoring force of the spring, the cylinders are pushed to move the fixed seats away from each other, and then the cap screwing sleeves are separated from the bottle caps, so as to quickly move away from the disinfectant bottles without affecting the transmission of the disinfectant bottles.

[0031] 2. The convenient replacement of cap screwing sleeves of different models and sizes during the cap screwing process is realized through the elastic elastic locking protrusion structure, so as to fully tighten the bottle caps during the processing. Specifically, the sizes of the snap seats - rubber sleeves engaged by the cap screwing sleeves of different models are different, which is reflected in the different outer radii. Therefore, when the bottle cap is small during work, a large-sized snap seat - rubber sleeve with a large outer radius is selected to fully screw the cap body during the cap screwing process.

[0032] 3. Lid-straightening mechanisms are respectively installed on the front and rear side walls of the mounting bracket. Each lid-straightening mechanism includes a mounting seat fixedly connected to the mounting bracket, and an elastic lid-straightening dial plate (made of elastic silicon steel sheet) is fixedly connected to the mounting seat. During the working process, before screwing the cap, the cap body touches the elastic lid-straightening dial plate (such as the elastic lid-straightening dial plate at the rear side position), and under the touch pressure of the elastic lid-straightening dial plate, the posture of the cap body is corrected to the horizontal state, which is convenient for screwing the cap.

[0033] After screwing the cap, the cap body is touched by the elastic lid-straightening dial plate on the other side, so that the operator can judge whether the cap is tightened. For example, when the bottle cap is not fully tightened, at this time, the cap body touches the elastic lid-straightening dial plate, causing elastic fluctuation of the elastic lid-straightening dial plate, and then the un-tightened cap body can be judged in time. And for the tightened cap body, since its height drops below the bottom of the elastic lid-straightening dial plate, it does not touch the elastic lid-straightening dial plate when passing through, and the elastic lid-straightening dial plate is not easy to shake. In this way, the un-fully tightened cap body can be judged in a simple and intuitive manner. Description of the Drawings

[0043] Embodiment 1

[0044] As Figures 1-4 shown, a disinfectant automatic capping device includes a capping mechanism. The capping mechanism includes a mounting frame 1 with a U-shaped structure (the same as the existing method, and the mounting frame 1 is installed on the transmission frame of the production line). On the front and rear sides inside the mounting frame 1, there are respectively assembled and connected capping components that cooperate with each other.

[0045] Specifically, the capping component includes a fixed seat 3. At the bottom of the fixed seat 3, there are assembled and connected capping motors 4 spaced apart on the left and right sides; the capping motors 4 are equipped with capping shafts 41 (the output shaft of the capping motor 4 is fixedly installed with the capping shaft 41, and the method is by connecting through a coupling). At the bottom of the capping shaft 41, there is assembled and connected a capping sleeve.

[0046] By friction between the capping sleeve and the side wall of the bottle cap, the four capping components are used in cooperation to fully tighten the cap body.

[0047] The above-mentioned fixed seats 3 are slidably connected; specifically, the capping mechanism further includes a cylinder mechanism for pushing the capping components to approach each other and then perform capping.

[0048] Specifically, the cylinder mechanism includes pushing cylinders 5 that respectively push the fixed seats 3 (the cylinder barrels of the pushing cylinders 5 are installed on the outer side walls of the mounting frame 1, and their piston rods slide in the mounting frame 1 and are fixed on the fixed seats 3. Specifically, at the lower ends of the front and rear side walls of the mounting frame 1, the pushing cylinders 5 are respectively fixedly assembled and connected, and the fixed seats 3 are pushed to approach each other and cap by the two side pushing cylinders 5). At the same time, the mutually facing side walls of the fixed seats 3 are slidably connected through slide rods 31 spaced apart on the left and right sides. The method is as follows: the fixed seats 3 are provided with chutes adapted to the slide rods 31, and the slide rods 31 are slidably connected between the chutes.

[0049] During capping, the capping components approach each other until the rotating capping sleeves abut against the bottle cap for capping. Specifically, each rotating capping sleeve abuts against the side wall of the cap body, and the driving direction of the cap body rotation is the tight-thread direction. Therefore, the cap body is fully tightened under the cooperation of the four capping sleeves.

[0050] In this process, since the capping assemblies on both the front and rear sides are driven by cylinders, during the working process, for caps of different sizes, under the drive of the cylinders, they can all achieve sufficient contact and friction with the caps, enabling the processing of products of various specifications.

[0051] After capping, in order to quickly detach from the bottle cap and enable the disinfectant bottle to continue to be transported on the conveyor line, at the left and right ends of the side wall of the above-mentioned fixed seat 3, there are respectively fixedly connected with spring slide rods 321 slidably connected to the mounting frame 1 (a retaining cap is threadedly connected to the outer end of the spring slide rod 321), and the spring slide rod 321 is slidably connected to the mounting frame 1.

[0052] Meanwhile, a spring 32 is sleeved on the spring slide rod 321, and the two ends of the spring 32 are respectively fixedly connected to the mutually facing side walls of the fixed seat 3 and the mounting frame 1.

[0053] After capping is completed, at this time, under the cooperation of the elastic restoring force of the spring 32, the pushing cylinder 5 moves the fixed seat 3 away from each other, and then the capping sleeve detaches from the bottle cap, achieving a quick separation from the disinfectant bottle and not affecting the transportation of the disinfectant bottle.

[0054] Embodiment 2

[0055] As Figures 1-4 shown, on the basis of the structure of Embodiment 1 in this embodiment, in order to further process products of various specifications, the capping sleeve is designed to be a conveniently detachable connection method. For example, when processing a cap with a too small size, by selecting a capping sleeve 42 with a larger size, it can be ensured that the capping sleeve 42 is in sufficient contact with the cap during the capping process.

[0056] Specifically, the capping sleeve 42 is detachably assembled on the capping shaft 41 through a buckle structure. The buckle structure includes a buckle seat 421 buckled at the bottom of the capping shaft 41, and a rubber sleeve 423 is sleeved on the buckle seat 421.

[0057] Specifically, the buckle structure further includes a buckle fixing base 411 fixedly connected to the bottom of the rotary cap shaft 41. The buckle fixing base 411 and the buckle seat 421 are locked through a plurality of elastic locking convex structures. The elastic locking convex structure includes an elastic locking convex 4111 elastically mounted on the buckle fixing base 411. A spherical buckle groove 422 for locking the elastic locking convex 4111 is formed on the inner side wall of the buckle seat 421. The locking end of the elastic locking convex 4111 is a curved end, and a guiding sliding groove 4221 communicating with the spherical buckle groove 422 is formed on the inner side wall of the buckle seat 421. Through the guiding sliding groove 4221, when the rotary cap sleeve 42 is being installed, the buckle seat 421 of the rotary cap sleeve 42 is aligned with the fixing base 3, and the elastic locking convex 4111 is aligned with the guiding sliding groove 4221 and pushed into the spherical buckle groove 422 along the guiding sliding groove 4221. In this way, rapid installation is achieved. Similarly, during the disassembly process, the opposite operation method is used to achieve quick installation and disassembly.

[0058] During this process, the elastic locking convex 4111 elastically expands and contracts. Specifically, a sliding groove for slidably connecting the elastic locking convex 4111 is formed on the fixing base 3, and an inner spring (not shown in the figure) is fixedly connected in the sliding groove. The inner spring is fixedly connected to the elastic locking convex 4111 (specifically, the part of the elastic locking convex 4111 that slidably connects to the fixing base 3 is a cylindrical sliding end, and the inner spring fixes the cylindrical sliding end to the bottom of the sliding groove).

[0059] In this way, it is convenient to replace rotary cap sleeves 42 of different models and sizes during the capping process, so as to fully tighten the bottle cap during the process. Specifically, the sizes of the buckle seats 421 - rubber sleeves 423 clamped by rotary cap sleeves 42 of different models are different, which is reflected in the different outer radii. Therefore, when the bottle cap is small during work, a large-sized buckle seat 421 - rubber sleeve 423 with a large outer radius is selected to fully turn the cap during the capping process.

[0060] Embodiment 3

[0061] As Figures 1-4 shown, on the basis of the structure of Embodiment 1, in order to correct the posture of the cap on the bottle mouth to the horizontal position before capping, which is convenient for capping (after the lower capping machine caps the bottle, the cap is carried on the bottle mouth, and the levelness of some caps is not enough, such as one side is high and the other side is low, resulting in inability to tighten during the capping process).

[0062] The front and rear side walls of the above-mentioned mounting bracket 1 are respectively provided with a lid-straightening mechanism. Each lid-straightening mechanism includes a mounting seat fixedly connected to the mounting bracket 1, and an elastic lid-straightening dial 2 (made of elastic silicon steel sheet) is fixedly connected to the mounting seat. The lower end of the elastic lid-straightening dial 2 is the lid-straightening part 21, which is used to press on the lid to correct the posture of the lid after pressing (when the bottle cap is placed on the bottle mouth and is twisted, it is corrected to a horizontal posture by pressing).

[0063] During the working process, before capping, the lid touches the elastic lid-straightening dial 2 (such as the elastic lid-straightening dial 2 at the rear side position). Under the pressing of the elastic lid-straightening dial 2, the posture of the lid is corrected to a horizontal state, which is convenient for capping.

[0064] After capping, the lid touches the lid through the elastic lid-straightening dial 2 on the other side, enabling the operator to judge whether the lid is tightened. For example, when the bottle cap is not fully tightened, at this time, the lid touches the elastic lid-straightening dial 2, causing elastic fluctuations of the elastic lid-straightening dial 2, and then it can be judged in time that the lid is not tightened. And for the tightened lid, since its height drops below the bottom of the elastic lid-straightening dial 2, it does not touch the elastic lid-straightening dial 2 when passing through, and the elastic lid-straightening dial 2 is not likely to shake. In this way, it is possible to judge the lid that is not fully tightened in a simple and intuitive manner.

[0065] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
