[0002] Cans are a common packaging in life. They usually use the sealing method to squeeze the lid and the can body to achieve the purpose of sealing. The sealing machine usually has 3 to 12 stations. If unqualified products appear after the cans are sealed, it is necessary to check which station has the problem. The traditional capping head has no features on the surface, so each station needs to be sealed separately to determine which station has the problem. It is time-consuming and labor-intensive. Therefore, the capping head needs to be improved. Utility Model Content

[0016] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0017] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] Reference below Figure 1-2 , the implementation of the can capping head proposed in the embodiment of the utility model is described in detail.

[0020] The can capping head according to the embodiment of the utility model is installed on a sealing machine and is suitable for sealing the cover body 2 and the can body together with the outer roller, and comprises: a capping head body 1.

[0021] Specifically, each sealing station of the sealing machine is provided with a capping head body 1, and each capping head body 1 is provided with a first concave point 11 and a second concave point 12 at the contact point with the cover body 2. The first concave point 11 and the second concave point 12 of each capping head body 1 have different angles. During the sealing operation, the first concave point 11 and the second concave point 12 will extrude two marks 21 with an angle on the cover body 2 of the corresponding station.

[0022] That is to say, the sealing machine is provided with a capping head body 1 and an outer roller, which jointly perform sealing operations on the cover body 2 and the can body. During the sealing process, the first concave point 11 and the second concave point 12 of the capping head body 1 and the outer roller are rotated and squeezed with the outer roller, so that two marks 21 with an angle are formed on the cover body 2. Since the angles of the first concave point 11 and the second concave point 12 of each sealing station are different, the angles of the two marks 21 formed are also different. When a sealing abnormality occurs, the station with the sealing abnormality can be judged by observing the two marks 21 on the cover body 2 discharged from the sealing station.

[0023] Therefore, through the two concave points on the capping head body 1 of each sealing station, two marks 21 are squeezed on the cover body 2 of the can during the sealing operation. When the sealing is abnormal, the station where the processing is abnormal is judged according to the angle formed by the two marks 21. The can capping head has a simple structure and can quickly determine the station where the sealing is abnormal.

[0024] For the reference of the included angle, a comparison gauge 3 is also included. The comparison gauge 3 is provided with a zero mark 31 and a plurality of station marks 32. The included angles of the zero mark 31 and the plurality of station marks 32 and the included angles of the two marks 21 of each station are matched. It can be understood that in order to avoid errors in naked eye observation, the comparison gauge 3 is provided with a zero mark 31 and a station mark 32 that match the angles of the first concave point 11 and the second concave point 12. When a sealing abnormality occurs, the mark on the comparison gauge 3 is compared with the two marks 21 on the cover body 2 for angle reference, so as to determine the station where the sealing abnormality is located. For example, the angle between the first concave point 11 and the second concave point 12 of the capping head body 1 of the first sealing station is 45°, and the angle between the first concave point 11 and the second concave point 12 of the second sealing station is 90°. A station mark 32 is set at an angle of 45° to the zero mark 31 on the comparison gauge 3, and a station mark 32 is set at an angle of 90° to the zero mark 31. When a sealing abnormality occurs, the zero mark 31 of the comparison gauge 3 is aligned with the first mark 21 on the cover body 2. If the second mark 21 is at a 45° position, it is judged that the abnormal station is the first station.

[0025] As for the shape of the comparison gauge 3, the comparison gauge 3 is annular, the mark is set on the annular surface of the annular ring, and the inner circle of the annular ring can be inserted into the cover body 2. It can be understood that by setting the comparison gauge 3 in an annular ring, the overall weight of the comparison gauge 3 can be reduced, so that it is convenient for the operator to hold and compare, and it is convenient to set the mark on the annular surface for easy observation. In addition, the inner circle of the annular ring can be inserted into the cover body 2, so that the comparison gauge 3 can be inserted into the cover body 2, and the operator can accurately observe the positions of the two marks 21, so as to quickly determine the work station with abnormal sealing.

[0026] As for the mark, the mark has a number and an indicator line, the number is set corresponding to the number of the sealing station, one end of the indicator line points to the center of the ring, and the other end of the indicator line points to the number. It can be understood that when there are many sealing stations, the angle between the two marks 21 is small, and each sealing station is marked with a number, and then the number on the comparison gauge 3 is marked with a number according to the angle between the first concave point 11 and the second concave point 12 of each capping head body 1, which is convenient for the operator to quickly observe and compare. The setting of the number and the indicator line can facilitate the operator to accurately compare the positions of the two marks 21, thereby ensuring the accuracy of reading.

[0027] As for the first concave point 11 and the second concave point 12, the first concave point 11 and the second concave point 12 are in the shape of circular holes, and the diameters of the first concave point 11 and the second concave point 12 are different. It can be understood that the capping head body 1 is usually processed by a machining machine. During the processing, the first concave point 11 and the second concave point 12 can be processed together with a milling cutter or a drill bit, thereby avoiding the increase in cost caused by subsequent processing. Among them, the first concave point 11 and the second concave point 12 can be of the same specification, the diameter can be 1mm, and the depth can be 0.8mm. The mark 21 is formed to facilitate the operator to observe clearly, and does not affect the overall appearance of the cover body 2.
