Description

Technical Field

[0001] The utility model relates to the technical field of food and medicine packaging machinery, in particular to an optical fiber fixing device used in a sterile environment. Background Art

[0002] Currently, the optical fiber detection fixing structure on equipment generally inserts one end of the optical fiber threading tube into a fixing base, then sets a set screw on the side of the fixing base, and tightens the set screw to fix the threading tube in the fixing base. This is a relatively simple structure. However, the set screw and the threading tube are in point contact, which has poor reliability. When touched by external force, the threading tube is prone to swing, causing the optical fiber detection point to shift, resulting in inaccurate counting and misjudgment of the "no bottle, no filling" function (i.e., the filling component does not perform filling if the optical fiber does not detect the bottle body). In addition, the countersunk threaded hole of the set screw is prone to forming sanitary blind spots. Utility Model Content

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Figures 1 to 3 An embodiment of the optical fiber fixture for use in a sterile environment according to the present invention is shown. This embodiment comprises a fixing base 1 and a threading tube 2. One end of the threading tube 2 is inserted into the fixing base 1. A clamping sleeve 3 is provided between the inner wall of the fixing base 1 and the outer wall of the threading tube 2. The fixing base 1 is provided with a locking sleeve 4. The inner wall of the locking sleeve 4 is provided with a locking flange 41, which abuts against one end of the clamping sleeve 3. A sealing member 5 is provided between the inner wall of the locking sleeve 4 and the outer wall of the threading tube 2. The fixing base 1 is mounted, for example, on a workbench of a filling machine. The sealing member 5 may be, for example, an O-ring, a sealing strip, or the like.

[0028] In the optical fiber fixing device for a sterile environment of this embodiment, the locking sleeve 4 is connected to the fixing seat 1 and presses the clamping sleeve 3 through the locking flange 41 of the inner wall. When the clamping sleeve 3 is subjected to force, it deforms and expands the gap between the fixing seat 1 and the threading tube 2, thereby fixing the threading tube 2. In addition, there is surface contact between the clamping sleeve 3 and the threading tube 2. Compared with the point contact structure of the existing set screw, it is beneficial to prevent the threading tube 2 from swinging after being subjected to force, has good reliability, and avoids the sanitary dead corner problem existing in the countersunk threaded hole; the sealing member 5 is used to seal the gap between the inner wall of the locking sleeve 4 and the outer wall of the threading tube 2 to prevent dust and other foreign matter from entering the interior.

[0029] See Figure 2 Furthermore, in this embodiment, a limiting flange 11 is provided on the inner wall of the fixing base 1, and the clamping sleeve 3 is located between the limiting flange 11 and the locking flange 41. The limiting flange 11 can reduce the gap between the fixing base 1 and the threading tube 2, thereby to a certain extent holding the threading tube 2 tightly. On the other hand, it can limit the maximum length to which the clamping sleeve 3 can be pressed into the fixing base 1, resulting in a simple and effective structure.

[0030] As a preferred embodiment, the clamping sleeve 3 is a conical structure and the end with a larger diameter abuts against the locking flange 41. The conical clamping sleeve 3 deforms when subjected to force, which can effectively tighten the gap between the fixing seat 1 and the threading tube 2.

[0031] As a preferred embodiment, the seal 5 and the clamping sleeve 3 are located on both sides of the locking flange 41. Specifically, the seal 5 is located on the upper side of the locking flange 41, and the clamping sleeve 3 is located on the lower side of the locking flange 41. The locking flange 41 is used to press the clamping sleeve 3 on the one hand, and can also provide axial support for the seal 5 on the other hand.

[0032] As a preferred embodiment, the locking sleeve 4 is threadedly connected to the fixing seat 1 , which is reliable, easy to disassemble, and convenient for adjusting the tightness of the clamping sleeve 3 .

[0033] See Figure 1 and Figure 3 In this embodiment, the optical fiber fixture for use in a sterile environment further includes a clamping assembly 6. A notch 12 is provided on the fixing base 1 for exposing the threading tube 2. The clamping assembly 6 clamps the exposed portion of the threading tube 2 and a rotation stop is provided between the fixing base 1. The locking sleeve 4 and the clamping sleeve 3 cooperate to initially secure the threading tube 2. The clamping assembly 6 then integrally connects the threading tube 2 to the fixing base 1, effectively preventing the threading tube 2 from moving up and down or rotating.

[0034] As a preferred embodiment, the clamping assembly 6 includes clamping blocks 61 arranged relatively on both sides of the wire threading tube 2 and threaded fasteners 62 (such as bolts, screws, etc.) for connecting the clamping blocks 61. The connection is reliable, the disassembly is convenient, and it is easy to adjust the clamping degree of the wire threading tube 2.

[0035] Furthermore, in this embodiment, the cross-section of the notch 12 is polygonal, and a matching groove is provided on the clamping block 61. The polygonal structure of the notch 12 and the corresponding groove provided on the clamping block 61 can effectively limit the relative rotation of the clamping block 61 and the fixing base 1.

[0036] As a preferred embodiment, the cross-section of the notch 12 is rectangular, and the exposed portion of the threading tube 2 is located on the long side of the rectangle, which can effectively limit the relative rotation of the clamping block 61 and the fixing base 1. Of course, in other embodiments, the cross-section of the notch 12 can also be other shapes such as a triangle, a square, or a pentagon.

[0037] As a preferred embodiment, the clamping assembly 6 is located below the locking sleeve 4. Specifically, the locking sleeve 4 is connected to the upper end of the fixing seat 1, the lower end of the fixing seat 1 passes through the table, and the clamping assembly 6 is arranged in the middle of the fixing seat 1. The overall layout is reasonable and convenient for disassembly and maintenance.

[0038] Although the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations. Therefore, any simple modifications, equivalent variations, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the scope of protection of the present invention.
