[0002] In the field of food packaging, the sealing technology for alcoholic beverages and beverages is becoming more and more mature. However, the installation and replacement of the sealing mechanism in the machine is a very complicated task. At present, most manufacturers adopt an integral design. For example, as shown in a Chinese invention patent entitled "Device for Sealing Containers" and published on September 8, 2010, with the announcement number "CN101827777B", the entire screw / capping mechanism needs to be removed when replacing it. Therefore, regular maintenance and cleaning of the capping / screwing head station is a very time-consuming and labor-intensive task, which greatly affects production efficiency. In this regard, there is a prior art that proposes to separate the transmission mechanism and the screwing head, but considering that the lifting and rotating motions need to be transmitted between the two, it is still necessary to carry out a complex installation with multiple steps, which is very time-consuming and labor-intensive.

[0003] Therefore, how to simplify the disassembly and assembly between the transmission mechanism and the capping head and maintain the stable transmission of the lifting and rotating motions has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

DETAILED DESCRIPTION

[0014] In order to clearly illustrate the technical features of this patent, this patent is elaborated in detail below through a specific implementation method and in combination with its accompanying drawings.

[0015] like Figure 1-3 As shown, the present case includes an upper connector 90, a lower connector 80 and a quick-release assembly 10 disposed therebetween. The upper connector 90 and the lower connector 80 are both columnar, and the upper portion of the side wall of the lower connector 80 is also fixedly connected with a truncated cone 801 arranged along its radial direction; there are a plurality of truncated cones that are evenly distributed along the circumference of the lower connector.

[0016] The quick-release assembly 10 includes a fixing sleeve 1, a slot seat 2, a driving sleeve 3, a first reset structure, and a second reset structure; The fixing sleeve 1 is fixedly sleeved on the bottom end of the upper connecting body 90, and the fixing sleeve 1 is provided with L-shaped guide grooves 11 of the same number as the truncated table 801, and the L-shaped guide grooves 11 include a first vertical groove 111 and a first transverse groove 112 adapted to the outer diameter of the truncated table 801; The slot seat 2 is sleeved on the lower part of the fixing sleeve 1, and the slot seat 2 maintains an upward movement trend under the action of the first reset structure; the slot seat 2 is provided with a second vertical groove 211 corresponding to the position of the L-shaped guide groove 11 and a second horizontal support platform 212, the second vertical groove 211 is located outside the first vertical groove 111, and is adapted to the outer diameter of the round table 801, and when there is no external force, the second horizontal support platform 212 is higher than the bottom of the first horizontal groove 112; The driving sleeve 3 is sleeved on the upper part of the fixed sleeve 1, and under the action of the second reset structure, the driving sleeve 3 maintains a downward movement tendency to press on the slot seat 2; a boss 31 corresponding to the position of the L-shaped guide groove 11 is provided on the bottom surface of the driving sleeve 3, and the boss 31 blocks the top of the first vertical groove 111 and covers the upper part of the first transverse groove 112. When there is no external force, the distance between the bottom surface of the boss 31 and the second transverse support 212 is smaller than the diameter of the round table 801, and the distance between the side surface of the boss 31 and the side wall of the second transverse support 212 is adapted to the diameter of the round table 801.

[0017] In this way, when in use, the upper connector 90 and the lower connector 80 are respectively fixedly installed on two parts that need to be coaxially plugged, such as the transmission mechanism and the capping head in the beer packaging equipment; when quickly installed, the lower connector 80 can be extended into the fixing sleeve 1 from bottom to top, and each round table 801 is aligned and enters each L-shaped guide groove 11, until the round table 801 in the lower connector 80 pushes up the boss 31 to expose the first transverse groove 112, as shown in FIG. Figure 6 shown.

[0018] Thereafter, the lower connector 80 is rotated so that the round platform 801 moves along the first transverse groove 112 and pushes the second transverse support 212 downward until it moves against the side wall of the second transverse support 212. At this time, the boss 31 loses external force and moves downward under the action of the second reset structure, so that the round platform 801 is stuck between the side surface of the boss 31 and the side wall of the second transverse support 212. In addition, due to the existence of the first reset structure, the up and down directions of the round platform 801 are stuck between the groove top of the first transverse groove 112 and the second transverse support 212, thereby realizing all-round positioning of the round platform 801. Figure 7 As shown, in this way, the lifting and rotating motions between the upper connecting body 90 and the lower connecting body 80 can be stably transmitted through the quick-install assembly after installation.

[0019] When disassembly is required, the driving sleeve 3 can be lifted up to expose the first transverse groove 112 , and then the lower connector 80 can be reversely rotated and pulled down to make the round platform 801 leave the fixing sleeve 1 along the L-shaped guide groove 11 .

[0020] This case is very simple and convenient in both the installation and disassembly process, so that when the operator replaces the capping head or repairs the capping head, he can use the quick-release assembly to conveniently complete the disassembly and assembly of the capping head without moving the transmission mechanism, and complete the accurate and efficient connection between the coaxial plug-in parts, and can maintain the stable transmission of lifting and rotating motion. Overall, this case has a series of advantages such as exquisite structure, simple operation and good locking effect after installation.

[0021] In the above: The first reset structure includes a first elastic member 4 and a positioning rod 7. The slot seat 2 is sleeved on the lower part of the fixed sleeve 1, and a plurality of waist-shaped holes 22 are evenly distributed along the circumferential direction on the slot seat 2. The number of the positioning rods 7 is consistent with the waist-shaped holes 22. The positioning rod 7 penetrates the waist-shaped holes 22 along the radial direction of the fixed sleeve 1 and is fixed on the surface of the fixed sleeve 1 by threads. An annular convex wing 12 is also provided at the bottom end of the outer wall of the fixed sleeve 1. The first elastic member 4 is sleeved on the fixed sleeve 1 and abuts against the annular convex wing 12 and the bottom surface of the slot seat 2, so that the slot seat 2 maintains an upward movement trend.

[0022] The second reset structure includes a pin shaft 5 and a second elastic member 6. A plurality of stepped holes 23 with a smaller upper portion and a larger lower portion are provided in the slot seat 2. The stepped holes 23 are arranged parallel to the axial direction of the slot seat 2. The pin shaft 5 passes through the stepped holes 23 from bottom to top and is then fixed on the drive sleeve 3 by means of threads. The second elastic member 6 is sleeved on the pin shaft 5 and rests between the stepped surface of the stepped hole 23 and the shaft head at the bottom end of the pin shaft 5, so that the drive sleeve 3 maintains a downward movement trend.

[0023] in addition: A transfer groove that is concave downwards is provided in the middle of the bottom of the first transverse groove 112 and in the middle of the second transverse support 212. Thus, during the disassembly and assembly process, that is, during the movement of the round platform 801 along the first transverse groove 112, when the lower part of the round platform 801 is temporarily stuck in the transfer groove, it can play a good temporary placement role, effectively avoiding equipment damage caused by disassembly and assembly errors.

[0024] The second horizontal support 212 is further provided with a protective baffle on one side away from the second vertical groove 211, and the distance between the inner wall of the protective baffle and the inner wall of the fixing sleeve 1 is adapted to the length of the round platform 801. Thus, after the round platform 801 is quickly installed, it is protected to a certain extent.

[0025] There are many specific implementation ways of the present invention. The above is only the preferred implementation mode of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the present invention. These improvements should also be regarded as the protection scope of the present invention.
