AI Technical Summary
The automatic gland press in the existing broth tube production is caused by the degeneration of the suction cup after multiple times of the capping, which leads to unstable work, which makes the suction cover not tight or the cover fall off. The lack of a buffer structure makes the broth tube easily crushed or the cover not tightened.
A broth tube gland pressure device is designed, adopting a cap mechanism and a retractable cap suction mechanism. The cap mechanism is equipped with a cap head, a cap mechanism concealing groove and a cap spring. The cap mechanism includes a suction cup, a telescopic part, a limiting part and a corrugated tube. Through the clever design, problems caused by suction cup degeneration and broth tube height error are avoided.
It effectively protects the suction cup, improves the gland efficiency and pass rate, and avoids the problem of the broth tube being crushed or the lid not being pressed tight.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of broth tube preparation equipment, in particular to a broth tube capping device. Background Art
[0002] Automatic capping machines are required for mass production of broth tubes. At present, ordinary test tube capping machines are generally used in the production of broth tubes, that is, an integrated capping machine in which the suction cup is also the capping head. Such capping machines will cause the suction cup to change its plastic properties after multiple capping (plastic will be denatured under the action of pressure), resulting in unstable operation and frequent capping. In addition, such capping machines are prone to crushing broth tubes or failing to tighten the lids. After analysis, it was found that the reason is that there is no buffer structure, so that broth tubes with height errors cannot be fully engaged with the lids or the pressing depth is greater than the set broth tube height. Utility Model Content

DETAILED DESCRIPTION
[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.
[0018] like Figure 1 and Figure 2As shown, a broth tube capping device comprises a capping mechanism 1 and a capping suction mechanism 2 which is retractable and hidden inside the capping mechanism 1. The capping mechanism 1 is located below a downward pressing punch A of a capping machine; the capping mechanism 1 is provided with a capping head 11, a capping suction mechanism hidden groove 12 and a capping spring 13. The capping head 11 is a hollow structure with large ends and a small middle. The capping spring 13 is sleeved in the middle part of the capping head 11. It is worth mentioning that one end of the capping spring 13 touches the top of the capping head 11, and the other end of the capping spring 13 touches the top of the capping head 11. The end touches the fixed frame B of the capping machine; the hidden groove 12 of the capping mechanism is located at the bottom of the capping head 11, and the capping mechanism 2 includes a suction cup 21 and a telescopic part 22. The telescopic part 22 passes through the hollow structure of the capping head 11 and is connected to the suction cup 21. The suction cup 21 is located inside the hidden groove 12 of the capping mechanism. It should be noted that the bottom area of the hidden groove 12 of the capping mechanism is smaller than the top area of the tube cover of the broth tube, so that the suction cup 21 can suck the lid during operation and the capping head 11 can touch the lid.
[0019] Specifically, the cover suction mechanism 2 also includes a limiter 211, which controls the extension length of the telescopic member 22. The telescopic member 22 is provided with a hose 221 and a bellows 222, wherein the hose 221 is located in the hollow structure of the capping head 11; one end of the bellows 222 is connected to the hose 221, and the other end is connected to the suction cup 21. In some embodiments, the suction cup 21 can be extended and retracted in the hidden groove 12 of the cover suction mechanism only by relying on the elasticity of the bellows 222. The principle is that when there is no contact with the cover, the bellows 222 naturally extends out of the hidden groove 12 of the cover suction mechanism. When the suction cup 21 sucks the cover, the downward pressing punch A pushes down to touch the capping head 11, and the bellows 222 is retracted into the hidden groove 12 of the cover suction mechanism under pressure, and the air valve of the suction cup 21 releases the air pressure, and the cover is released to complete the capping of the broth tube.
[0020] In the above embodiment, although the basic operation of capping the broth tube can be completed, it may cause mechanical strain of the bellows 222 over a long period of time, resulting in reduced stability. Further improvements to the above embodiment:
[0021] A clamping block 223 is provided at the end of the bellows 222, and the clamping block 223 cooperates with the limiting member 211 to limit the extension length of the telescopic member 22. A telescopic spring 224 is sleeved on the bellows 222 to enable the bellows 222 to move, and one end of the telescopic spring 224 touches the hidden groove 12 of the suction cover mechanism, and the other end touches the clamping block 223. The limiting member 211 is composed of a limiting block 212 and a limiting clamping block 213, the limiting block 212 is welded to the inner wall of the hidden groove 12 of the suction cover mechanism, the limiting clamping block 213 is fixed to the limiting block 212 by bolts, and the limiting clamping block 213 touches the clamping block 223.
[0022] Detailed description of the working principle:
[0023] The broth tube capping device is a component of the capping machine. The entire machine is controlled by a control panel, and the controlled components mainly include the valves of the air pressure system. When working, the broth tube capping device is located below the downward punch A of the capping machine. The downward punch A is controlled by the air valve to contact the capping head 11, so that the capping head 11 fixed on the fixed frame B of the capping machine moves downward, thereby capping. When the downward punch A moves upward, the capping head 11 is restored under the action of the capping spring 13.
[0024] When sucking the lid, the suction cup 21 protrudes from the outside of the hidden groove 12 of the lid sucking mechanism, and sucks the lid under the control of the air valve. The capping head 11 moves downward, one end of the lid is inserted into the broth tube, and the other end touches the bottom of the capping head 11. The capping head 11 continues to move downward, and the lid and the broth tube are completely engaged. Among them, the suction cup 21 is retracted into the hidden groove 12 of the lid sucking mechanism due to the reaction force of the broth tube, so as to protect the suction cup 21. When the capping is completed, the air valve controls the suction cup 21 to release the lid, and the downward pressing punch A moves upward. The suction cup 21 returns to its original position under the action of the telescopic spring 224, that is, it protrudes from the outside of the hidden groove 12 of the lid sucking mechanism.
[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
