Description

Technical Field

[0001] The utility model relates to the field of medicine canning, in particular to a capping knife arm structure of an oral liquid filling and rolling machine. Background Art

[0002] During the capping process of the oral liquid filling and rolling mill, the cutter arm structure contained numerous vulnerable parts. The deep groove ball bearing connected to the cutter had a lifespan shorter than the expected six months. Furthermore, despite the solid material and robust structure of the connecting arm itself, the transmission shaft between them was experiencing significant wear. This was primarily due to the high frequency of operation typically required for oral liquid production, which increased mechanical stress on the bearings and shortened their lifespan. Furthermore, the lubricant could become contaminated during production, either from frequently used cleaning fluids or from the liquid medicine itself. This ultimately reduced the lubricant's effectiveness, further shortening the already short lifespan.

[0003] To address the above issues, we have made a series of improvements. Utility Model Content

[0018] The present invention will be further described below in conjunction with specific embodiments. It should be understood that the following embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0019] Example 1

[0020] Figure 1 It is a structural diagram of the present utility model. Figure 2 Schematic diagram of the structure of the protective cover.

[0021] like Figure 1As shown, a capping cutter arm structure for an oral liquid filling and rolling machine includes: a needle roller bearing with a screw 100, an upper swing arm 200, a lower swing arm 300, a lubrication channel 400, a cutter shaft 500, a cutter arm 600, a spring 700, a protective cover 800, a lever 900, a cutter 1000, and a deep groove ball bearing 1100. One end of the needle roller bearing with a screw 100 is connected to the capping system 1, and the other end of the needle roller bearing with a screw 100 is connected to the upper swing arm 200. The upper swing arm 200 is connected to the lower swing arm 300. The lubrication channel 400 is provided at the connection between the upper swing arm 200 and the lower swing arm 300. One end of the guillotine shaft 500 is connected to the lower swing arm 300. The other end of the guillotine shaft 500 is connected to the guillotine arm 600. The guillotine arm 600 is connected to one end of a lever 900 via a spring 700. The other end of the lever 900 is connected to a deep groove ball bearing 1100. One end of a protective cover 800 is connected to the outer wall of the lever 900. The other end of the protective cover 800 is provided at the side end of the deep groove ball bearing 1100. The deep groove ball bearing 1100 is connected to the guillotine 1000.

[0022] like Figure 2 As shown, the protective cover 800 includes: a cover plate 810, a spring hinge 820, a blade 830, a front connecting hole 840 and a rear connecting waist hole 850. The front connecting hole 840 and the rear connecting waist hole 850 are respectively arranged at the front end and the rear end of the cover plate 810. The cover plate 810 is fixedly connected to the outer wall of the lever 900 through the front connecting hole 840. The cover plate 810 is slidingly connected to the side end of the deep groove ball bearing 1100 through the rear connecting waist hole 850. The spring hinge 820 connects the top end of the cover plate 810 and the bottom end of the blade 830.

[0023] The connection point between the upper swing arm 200 and the lower swing arm 300 is a connecting channel 210 , which connects the upper swing arm 200 and the lower swing arm 300 via a connecting shaft. A lubrication channel 400 is provided above the connecting channel 210 . A pipe 410 is provided on the lubrication channel 400 .

[0024] As a component of the capping system, the principle of the present invention is basically unchanged, and as a transmission capping cutter structure, it is not complicated in itself, so it will not be described in detail.

[0025] As mentioned in the background art, a problem with current milling arm structures is the short lifespan of some components, which impacts production efficiency. First, the present invention adds a lubrication channel 400. This channel is located above the connecting channel 210 and can be connected directly to the pipe 410, or to an automatic roller skating system or manual oiling. This channel transfers lubricant to the drive shaft within the connecting channel 210, ensuring that the connection between the upper swing arm 200 and the lower swing arm 300 remains lubricated, reducing wear.

[0026] On the other hand, the problem of the lack of protection of the overall connection and the body of the deep groove ball bearing 1100 has also been mentioned in the background technology. The solution of the present utility model is to add a protective cover 800 structure. First of all, the basic composition of the protective cover 800 is a cover plate 810 and a blade 830, and the two are connected by a spring hinge 820. The purpose of this structural design is to allow the blade 830 and the cover plate 810 to be folded, while at the same time being able to remain fixed on the same side. The folding function facilitates the removal of the deep groove ball bearing 1100 when replacing it. Ensuring fixation on the same side is to expand the overall protection range. The front connection hole 840 is to ensure that the protective cover 800 is stably fixed, while the rear connection waist hole 850 is a sliding connection to ensure that the entire rolling cutter 1000 avoids rigid contact during use, which affects normal use.

[0027] Compared with the traditional technology, the utility model reduces the wear between the swing arms through the lubrication channel and protects the deep groove ball bearing and the connection thereof by adding a protective cover to prevent dust from affecting the service life.

[0028] The above describes the specific implementation of the present invention, but the present invention is not limited thereto. As long as it does not deviate from the purpose of the present invention, the present invention can also have various changes.
