[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] like Figure 1-5The present invention shows a filling mandrel sterilization cover lifting structure, which is installed on the mandrel filling unit of the blowing, filling and sealing machine, and includes a mandrel sterilization cover 16. A groove is provided above the mandrel sterilization cover 16, and a sealing ring 17 is provided at the upper end of the groove; the left side of the mandrel sterilization cover 16 is connected to a left guide slide groove assembly for lifting the mandrel sterilization cover 16; the right side of the mandrel sterilization cover 16 is connected to a right guide slide groove assembly for lifting the mandrel sterilization cover 16; an extrusion head 18 is provided above the mandrel sterilization cover 16, and a preset distance is provided between the upper end surface of the mandrel sterilization cover 16 and the extrusion head 18.

[0028] Specifically, the left guide slot assembly includes a left guide member 1, on which a left guide slot 101 is provided, and a first lower sliding bar 3 is slidably connected in the left guide slot 101, so that the first lower sliding bar 3 can slide back and forth in the left guide slot 101; the upper end surface of the first lower sliding bar 3 slides in contact with the first upper sliding bar 4, and the first lower sliding bar 3 and the first upper sliding bar 4 are both L-shaped, and the mutual contact surfaces are matching arc-shaped surfaces, and they slide in abutment with each other; a first pin shaft 5 passes through the inner hole at the rear end of the first upper sliding bar 4, and the first pin shaft 5 is threadedly connected to the inner wall of the left guide slot 101, so that the first upper sliding bar 4 can only move up and down in the left guide slot 101; the front end of the first lower sliding bar 3 is connected to the first adjusting bolt 9. The first adjusting bolt 9 includes a first threaded rod 91 and a second threaded rod 92 connected to each other. The first threaded rod 91 is connected to the first threaded hole at the front end of the left guide member 1, and the second threaded rod 92 is connected to the second threaded hole at the front end of the first lower sliding bar 3. The thread directions of the first threaded rod 91 and the second threaded rod 92 are opposite. The cross-sectional diameter of the first threaded rod 91 is greater than the cross-sectional diameter of the second threaded rod 92. A first limiting step 11 is provided at the front end of the left guide member 1, and a first threaded hole is provided on the side wall of the first limiting step 11.

[0029] Specifically, adjust the first adjusting bolt 9 so that the first lower sliding bar 3 in the left guide groove 101 moves toward the side of the first limiting step 11. Since the first upper sliding bar 4 and the first lower sliding bar 3 are two opposite L-shaped structures, when the first lower sliding bar 3 moves toward the side of the first limiting step 11, the first upper sliding bar 4 will move upward.

[0030] Specifically, the right guide slot assembly includes a right guide member 2; a right guide slot 201 is provided on the right guide member 2, and a second lower sliding bar 6 is slidably connected in the right guide slot 201, so that the second lower sliding bar 6 can slide back and forth in the right guide slot 201; the second lower sliding bar 6 is slidably connected to the second upper sliding bar 7, and the second lower sliding bar 6 and the second upper sliding bar 7 are both L-shaped, and the mutual contact surfaces are matching arc-shaped surfaces, and they slide in abutment with each other; a second pin shaft 8 passes through the inner hole at the rear end of the second upper sliding bar 7, and the second pin shaft 8 is threadedly connected to the inner wall of the right guide slot 201, so that the second upper sliding bar 7 can only move up and down in the right guide slot 201; the front end of the second lower sliding bar 6 is connected to the second adjusting bolt 10. The second adjusting bolt 10 includes a third threaded rod 1001 and a fourth threaded rod 1002 connected to each other. The third threaded rod 1001 is connected to the third threaded hole at the front end of the right guide member 2, and the fourth threaded rod 1002 is connected to the fourth threaded hole at the front end of the second lower sliding bar 6. The thread directions of the third threaded rod 1001 and the fourth threaded rod 1002 are opposite. The cross-sectional diameter of the third threaded rod 1001 is greater than the cross-sectional diameter of the fourth threaded rod 1002. The front end of the right guide member 2 is provided with a second limiting step 12, and the third threaded hole is provided on the side wall of the second limiting step 12.

[0031] The end of the right guide member 2 facing away from the core shaft sterilization cover 16 is connected to the sensor bracket 13, and two mutually perpendicular sensors 14 are connected to the outer side of the sensor bracket 13; the side of the core shaft sterilization cover 16 close to the sensor 14 (the sensor can be a current sensor) is connected to the actuator 15 (the actuator model can be CL20).

[0032] Specifically, adjust the second adjusting bolt 10 so that the second lower sliding bar 6 in the right guide groove 201 moves toward the second limit step 12. Since the second lower sliding bar 6 and the second upper sliding bar 7 are two opposite L-shaped structures, when the second lower sliding bar 6 moves toward the second limit step 12, the second upper sliding bar 7 will move upward; the core shaft sterilization cover 16 is above the first upper sliding bar 4 and the second upper sliding bar 7, so the core shaft sterilization cover 16 will also move upward, and when the actuator 15 installed on the core shaft sterilization cover 16 is close to the sensor 14, the indicator light on the sensor 14 will light up.

[0033] Specifically, the left side of the core shaft sterilization cover 16 is connected to the upper end surface of the first upper sliding bar 4; the right side of the core shaft sterilization cover 16 is connected to the upper surface of the second upper sliding bar 7; the front end of the left side of the core shaft sterilization cover 16 contacts the first limiting step 11; the front end of the right side of the core shaft sterilization cover 16 contacts the second limiting step 12.

[0034] Working principle:

[0035] Before the BFS equipment is cleaned and sterilized online, it is necessary to lift the mandrel sterilization cover 16 to achieve sealing with the extruder head 18, and adjust the first adjusting bolt 9 and the second adjusting bolt 10 so that the first lower sliding bar 3 in the left guide slot 101 and the second lower sliding bar 6 in the right guide slot 201 move toward the first limit step 11 and the second limit step 12 respectively. Since the first upper sliding bar 4 and the first lower sliding bar 3 are two opposite L-shaped structures, when the first lower sliding bar 3 moves toward the first limit step 11, the first upper sliding bar 4 will move upward; similarly, since the second lower sliding bar 6 and the second upper sliding bar 7 are two opposite L-shaped structures, when the second lower sliding bar 6 moves toward the second limit step 12, the second upper sliding bar 7 will move upward; at the same time, the mandrel sterilization cover 16 is above the first upper sliding bar 4 and the second upper sliding bar 7, so the mandrel sterilization cover 16 will also move upward, and when the trigger 15 installed on the mandrel sterilization cover 16 is close to When the sensor 14 is moved, the indicator light on the sensor 14 will light up, indicating that the mandrel sterilization cover 16 is lifted into place, and the mandrel sterilization cover 16 is completely sealed with the extrusion head 18 above. At this time, the filling equipment can be cleaned and sterilized online; when the online cleaning and online sterilization of the blowing and filling equipment are completed, the specific implementation method is opposite to the above steps, and the first adjusting bolt 9 and the second adjusting bolt 10 are adjusted so that the first lower sliding bar 3 in the left guide slot 101 and the second lower sliding bar 6 in the right guide slot 201 move toward the side away from the first limit step 11 and the second limit step 12 respectively, and the first upper sliding bar 4 and the second upper sliding bar 7 will move downward. At this time, the mandrel sterilization cover 16 will also move downward, and the trigger 15 installed on the mandrel sterilization cover 16 will be away from the sensor 14, and the indicator light on the sensor 14 will go out, indicating that the mandrel sterilization cover 16 has dropped into place, the mandrel sterilization cover 16 is completely separated from the extrusion head 18 above, and the mandrel sterilization cover 16 can be removed.

[0036] Therefore, by using a filling mandrel sterilization cover lifting structure of the present invention, the mechanized operation of the filling mandrel sterilization cover lifting structure is realized, the convenience and mechanization degree of the operation of the blow-fill-seal equipment are improved, and the number of cleaning times of the outer surface of the filling mandrel sterilization cover is reduced, thereby improving the efficiency of the blow-fill-seal equipment in producing products.
