Description

Technical Field

[0001] The utility model relates to the technical field of liquid food capping, in particular to an automatic capping machine. Background Art

[0002] Capping is an important process in the packaging of bottled products in the food, medicine, chemical and other industries. The sealing film at the bottle mouth is the rubber cap, which is usually made of PVC shrink film. After shrinkage, it can be tightly wrapped around the bottle cap to prevent dust, water and moisture.

[0003] After the center guide column of the existing capping machine stretches the rubber cap, due to the gap between the rubber cap and the guide column, the rubber cap cannot be put into the bottle cap in a circular state, but falls into the bottle cap in an elliptical shape. The short semi-axis of the ellipse of the rubber cap easily touches the edge of the bottle cap, resulting in the rubber cap not being able to be put into the bottle cap vertically and accurately, which in turn causes the rubber cap to be lost or put into the bottle cap crookedly, resulting in the phenomenon of no rubber cap or wrinkled rubber cap packaging, and the rubber cap needs to be manually removed and re-capped.

[0004] On the other hand, the position and adjustment of the cap-putting machine's inductive electric eye will also affect the accuracy of cap-putting. The traditional cap-putting machine's inductive electric eye adjustment device adopts the form of coarse adjustment left and right and up and down within the frame, which is difficult to adjust and it is difficult to find the exact position quickly.

[0023] See also Figure 1 This embodiment discloses an automatic capping machine for use in conjunction with a bottle conveying mechanism. The bottle conveying mechanism typically utilizes a linear conveyor coupled with a bottle-separating screw 6 to deliver bottles to the automatic capping machine at equal intervals. The automatic capping machine comprises a material guide assembly, a guide post assembly, a cutter disc assembly 4, and a brush assembly 5, all connected via a mounting frame for the capping machine. The material guide assembly is used to transfer label film to the guide post assembly, which inserts and stretches the label film. The label film is then transferred to the cutter disc assembly 4 for cutting. The brush assembly 5 pushes the cut label film and inserts it onto the bottle caps.

[0024] The material guide assembly includes a material rack group 1 and a pulley group 13. The material rack group 1 is used to store label film materials, and it and the pulley group 13 are used to support and transport label film materials. The structure and coordination of the material guide assembly belong to the existing technology, and its structure will not be described in detail in this embodiment.

[0025] The guide post assembly includes a central guide post 2 and a guide post positioning portion 14 for positioning the central guide post 2. The central guide post 2 adopts an existing column structure with a pointed cone-shaped top structure. The guide post positioning portion 14 is fixed by a cap whole machine support plate provided behind the central guide post 2, such as Figure 1 As shown, the guide post positioning portion 14 includes positioning wheel assemblies respectively provided on the left and right sides of the central guide post 2 , and the positioning wheel assemblies on the left and right sides respectively abut against the central guide post 2 to fix its position.

[0026] Specifically, the single-sided positioning wheel assembly includes at least two positioning wheels distributed along the height of the central guide column 2, and a mounting block for connecting the two positioning wheels. The positioning wheels are rotatably connected to the mounting block, creating rolling friction between the positioning wheels and the label film, thereby allowing the label film to move smoothly downward with the cooperation of the positioning wheels. Preferably, the outer surface of the positioning wheels is covered with a protective layer made of a soft material such as rubber or silicone to prevent damage to the label film. Similarly, each wheel described below is also covered with a protective layer.

[0027] More specifically, in this embodiment, the positioning wheel sets are movable, that is, the two positioning wheel sets are constructed to be able to move towards or away from the central guide column 2 respectively, so as to facilitate the replacement or orientation adjustment of the central guide column 2.

[0028] In one embodiment, the guide post positioning portion 14 further includes a screw extending perpendicular to the center guide post 2. This screw is fixedly connected to the machine support plate behind the center guide post 2 via a mounting bracket. The screw is rotatably connected to the mounting bracket. The aforementioned mounting blocks for connecting the positioning wheel are each threadedly connected to the screw, with the threads of the two mounting blocks arranged in opposite directions. A drive handle is connected to one end of the screw. By rotating the drive handle, the two mounting blocks can be controlled to move toward or in opposite directions.

[0029] In another embodiment, the lead screw is provided in two groups, corresponding to the positions of the positioning wheel groups on both sides respectively. In this embodiment, the lead screws are rotatably connected to the mounting base respectively, and the two mounting blocks are threadedly connected to the lead screws on the corresponding sides respectively, and the two groups of lead screws are respectively connected to corresponding driving handles. By rotating the driving handles, the orientation of the positioning wheel groups can be adjusted respectively, so that the position of the center guide column 2 can be positioned more flexibly, so that it can be more accurately fitted to the position of the label film material transmitted by the pulley group 13 and the bottle mouth position, and promote the label film material to be accurately fitted on the bottle mouth of the packaging bottle.

[0030] After the label film is stretched by the central guide column 2, there will often be creases. The creases will cause the label film to be inserted into the bottle mouth in a shape close to an ellipse, which will increase the loss rate of the cap. In order to reduce the creases, in this embodiment, the guide column assembly also includes a creasing wheel set 3, which is connected to the equipment table. Figure 2 and Figure 3The creasing wheel assembly 3 includes a support base 32 fixedly connected to the installation table of the whole machine, a support frame 33 fixedly connected to the top of the support base 32, and a creasing wheel body 31 rotatably connected to the support frame 33. The creasing wheel body 31 is fitted to the central guide column 2 and corresponds to the fold position of the label film. During the downward movement of the label film, the creasing wheel body 31 can be pressed on the fold of the label film and reduce its mark, so that the label film can be put into the bottle mouth in a shape close to a circle, thereby improving the accuracy of the capping.

[0031] like Figure 1 As shown, the central guide column 2 passes through the equipment table and cooperates with the cutter head assembly 4 connected to the bottom of the whole machine installation table. The cutter head assembly 4 is used to cut the label film material set on the central guide column 2. Figure 4 It includes a plurality of circular knife seats 41 arranged in an interval ring around the central guide column 2 and a cutting knife 42 connected to the circular knife seat 41. The circular knife seat 41 can adopt a gear structure or a pulley structure. Correspondingly, each circular knife seat 41 is connected by a gear belt or a synchronous belt. One circular knife seat 41 is driven to rotate by the driving group 11, thereby driving the other circular knife seats 41 to rotate and cut. The structure of the cutter disc assembly 4 belongs to the existing technology and its structure will not be further described here.

[0032] The brush assembly 5 includes at least two high-speed rotating brush wheels, one corresponding to each side of the lower end of the central guide post 2. When the bottle runs directly below the central guide post 2, the high-speed rotating brush wheels brush the cut label film onto the bottle mouth. It is understood that the brush assembly 5 also includes a drive motor for driving the brush wheels, which is fixedly connected to the corresponding position of the entire device.

[0033] In order to accurately detect when the bottle reaches the capping position, the automatic capping machine further includes a shooting component 7, which includes a bottle-viewing electric eye 71. In this embodiment, the bottle-viewing electric eye 71 is movable so as to be adaptively adjusted according to the position of the central guide column 2, thereby accurately capturing the position of the bottle. Specifically, the shooting component 7 includes an electric eye adjustment unit 72 for adjusting the position of the bottle-viewing electric eye 71. Figure 5 As shown, the electric eye adjustment unit 72 includes an electric eye mounting sleeve of a predetermined length. One end of the sleeve is fixedly connected to the entire device, with its length corresponding to the direction of travel of the packaged bottles and its installation height corresponding to the position of the bottle mouth. The interior of the electric eye mounting sleeve houses a rotatable threaded sleeve and a screw threaded with the sleeve. One end of the screw sleeve extends out of the mounting sleeve and is fixedly connected to a knob. The bottle-viewing electric eye 71 is fixedly connected to the other end of the screw. By turning the knob, the position of the bottle-viewing electric eye 71 can be precisely adjusted, shortening adjustment time and improving the accuracy of capping.

[0034] During use, first adjust the guide post assembly. Using the guide post positioning member 14, position the center guide post 2 to the position corresponding to the downward movement of the label film and secure it. Manually place the label film into the material rack assembly 1. The label film passes over the pulley assembly 13 and through the center guide post 2 into the brush assembly 5. Adjust the bottle conveyor mechanism's lifting mechanism 8 to ensure the proper height between the bottle and the lower edge of the center guide post 2. Adjust the knob on the sensor adjustment member 72 to align the bottle sensor 71 with the centerline of the center guide post 2.

[0035] The bottles are transported by the conveyor and separated at equal distances by the bottle-separating screw 6. When the bottle-lighting electric eye 71 detects that a bottle has passed, the drive group 11 drives the cutter assembly 4 to cut the label film. At the same time, the brush wheel of the brush assembly 5 brushes the cut label film down and puts it into the bottle cap. The bottle continues to be transported, and the label film is attached by the brush group 9. Finally, the label film is hot-pressed on the bottle cap through the shrink furnace 12.

[0036] It can be understood that the above-mentioned action processes are all controlled by the control module 10. The control module 10 may specifically include a control chip or a single-chip microcomputer that can control the material guide assembly, the knife disc assembly 4 and other structures according to a predetermined program, so that the cap machine equipment can start, stop or perform other actions according to a preset process.

[0037] The automatic capping machine provided in this embodiment can adjust and align the position of the central guide column 2 by setting an adjustable guide column assembly. Combined with the indentation wheel group 3, the label material film can be put on the bottle cap of the packaging bottle in a relatively regular circular shape, thereby improving the accuracy of capping. And by setting the electric eye adjustment part 72 of the screw structure, not only can the position of the control bottle electric eye 71 be adjusted quickly and conveniently, but also its position positioning can be made more accurate, thereby further improving the accuracy of capping.
