Description

Technical Field

[0001] The utility model relates to a film-breaking knife structure, in particular to a cleaning liquid film-breaking device. Background Art

[0002] After the full-automatic high-speed coagulation tester is used, it needs to be cleaned. Generally, a cleaning liquid tooling is directly installed for cleaning. When the cleaning liquid tooling is installed on the coagulation tester, a film-breaking device is required to break the film so that the cleaning liquid can enter the cleaning bucket of the coagulation tester for cleaning. The film-breaking structure of the existing cleaning device does not have a limiting function. The cleaning liquid bucket cannot be effectively limited and will tilt, resulting in the overflow of the cleaning liquid, affecting the cleaning effect. Moreover, the design of the existing film-breaking knife structure is also unreasonable, inconvenient to use, and has a poor film-breaking effect.

[0003] In summary, the utility model designs a cleaning liquid film-breaking device. Summary of the Utility Model

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Referring to Figure 1-7 , the following technical solutions are adopted in this specific embodiment: a cleaning liquid film-breaking device, including a film-breaking structure arranged at the opening of the cleaning bucket A. The film-breaking structure includes a limiting groove 1 and a film-breaking knife 2. The film-breaking knife 2 is arranged in the limiting groove 1 and cooperates with the sealing film of the cleaning liquid bucket B. The end face of the limiting groove 1 is higher than the tip of the film-breaking knife 2. Exhaust holes 3 are arranged on the side wall of the limiting groove 1, and liquid discharge holes 4 are arranged on both the inner and outer sides of the film-breaking knife in the limiting groove 1.

[0023] It should be noted that the notch of the limiting groove 1 is provided with a right R arc for guiding, which is convenient for entering the groove.

[0024] It should be noted that the film-breaking knife 2 is provided with three blade inclined surfaces 21, and the included angle between the blade inclined surface 21 and the center line is 25°-40°, and the three blade inclined surfaces 21 are evenly divided.

[0025] It should be noted that the included angle between the blade inclined surface 21 and the center line is 30°

[0026] It should be noted that the middle of the film-breaking knife 2 adopts a hollow structure to reduce weight while ensuring the strength of the three blades, and to ensure sufficient space for backflow.

[0027] The film-breaking knife 2 is made of 304 stainless steel.

[0028] In addition, a hole-expanding guiding inclined surface 22 is arranged obliquely below the inclined surface of the blade 21, and the hole-expanding guiding inclined surface 22 and the inclined surface of the blade 21 are in the same plane.

[0029] The usage method of this specific embodiment is as follows:

[0030] The first step: Align the mouth of the cleaning liquid bucket (original with sealed film) with the film-breaking knife and lower it. The film is automatically broken by gravity.

[0031] The second step: Rotate the cleaning liquid bucket to increase the damaged surface of the film, which can also be called hole expansion.

[0032] The third step: Remove the empty bucket after the cleaning liquid is drained.

[0033] The end face of the limit groove in this specific embodiment is higher than the tip of the film-breaking knife. The right R arc of the limit groove opening is for guiding, which is convenient for entering the groove. The limit groove is deep, which can effectively limit the cleaning bucket and prevent it from tipping over effectively. Sufficient drainage holes and exhaust holes ensure smooth liquid flow and prevent overflow. The hollow design in the middle of the film-breaking knife reduces weight while ensuring the strength of the three blades, and ensures sufficient space for backflow. The hole-expanding backflow inclined surface and the inclined surface of the blade are in the same plane; the film-breaking knife is made of 304 stainless steel and can be used directly after processing without surface treatment. It is corrosion-resistant and will not contaminate the cleaning liquid.

[0034] Example 1: In this example, the included angle between the three blade inclined surfaces of the film-breaking knife and the center line is 40°, the three blade inclined surfaces are evenly divided, and any two blade angles are 96.14°. The film-breaking effect is poor. The film-breaking stroke required is: 19.66 mm.

[0035] Example 2: In this example, the included angle between the three blade inclined surfaces of the film-breaking knife and the center line is 25°, the three blade inclined surfaces are evenly divided; any two blade angles are 72.41°. The film-breaking effect is good. The film-breaking stroke required is: 35.38 mm, and the usage limit for the bucket mouth height of 53 mm is 34.5 (53 - 18.5) mm.

[0036] Example 3: In this example, the included angle between the three blade inclined surfaces of the film-breaking knife and the center line is: 30°, the three blade inclined surfaces are evenly divided; any two blade angles are 81.79°. The film-breaking effect is good. The film-breaking stroke required is: 28.58 mm.
