Hose filling and tail sealing machine

Abstract

The invention discloses a hose filling and tail sealing machine. The hose filling and tail sealing machine comprises a rotary plate and a plurality of hose cup bases, wherein the hose cup bases can rotate; a filling mechanism, a benchmarking nitrogen filling mechanism and a tail sealing mechanism are arranged along the rotating direction of the rotary plate in turn; the benchmarking nitrogen filling mechanism comprises a rotating shaft, a sleeve and a photoelectric color mark sensor, wherein the rotating shaft can ascend and descend, the sleeve and the rotating shaft are arranged coaxially, the sleeve can rotate, and the photoelectric color mark sensor is fixedly arranged on one side of the sleeve; the hose cup base can rotate along with the rotation of the rotating shaft; the inner diameter of the sleeve is not smaller than the outer diameter of a hose; the circumferential direction of the sleeve is provided with a plurality of vent holes; a nitrogen filling nozzle which can ascend and descend is fixedly arranged in the center of the sleeve; the bottom of the nitrogen filling nozzle extends from the sleeve; the top of the nitrogen filling nozzle is connected with a nitrogen cylinder. According to the hose filling and tail sealing machine, the automatic benchmarking can be performed on the hose after the filling is achieved due to the benchmarking nitrogen filling mechanism and meanwhile the air inside the hose can be discharged and accordingly the quality life of the paste liquid in the hose is extended.

Description

technical field [0001] The invention relates to a packaging auxiliary device, in particular to a tube filling and sealing machine. Background technique [0002] With the improvement of people's material living standards and the rapid development of the modern packaging industry, various daily necessities, cosmetics and medicines packaged in hoses are becoming more and more popular. The demand for packaging has also increased significantly. [0003] In the cosmetics, daily use, medicine, and food industries, there are many products packaged in tubes, such as facial cleanser, toothpaste, ointment, condiments, and so on. There are many process steps. For example, some simple ultrasonic filling and sealing machines in China have multiple processes such as filling, sealing, tail cutting, and tube discharge. Since the hose is mostly in the shape of a cylinder, after the end is sealed, the pipe head becomes a round shape, and the pipe tail is flat, forming two obvious sides, and ...

AI Technical Summary

Problems solved by technology

[0007] 1. The rotating taper sleeve directly contacts the hose to be marked, and drives the hose to be marked and the floating rotating pipe seat to rotate to perform the marking. The following problems will occur in this process: the hose to be marked, the rotating taper sleeve and the floating The rotating tube base needs to rotate synchronously, so the three should be closely matched. If the fit is too tight, the shape of the hose will be deformed, which will affect the appearance quality of the product. At the same time, the position of the mark will change, and the sensor may make a wrong judgment.

If the fit is too loose, the two will cause the rotation to be out of sync, resulting in inaccurate alignment

In addition, if the hose to be marked is too tightly matched with the rotating drogue, it is not conducive to the disengagement of the rotating drogue or when it is disengaged, it will cause the position of the hose that has been targeted to change.

[0008] 2. The floating and rotating tube base must be able to rotate, but also need to be able to lift up and down, so the structure of the floating and rotating tube base is complicated, and a benchmarking device requires multiple such floating and rotating tube bases, so the overall manufacturing cost is high

[0011] 1. The hose cup holder must be able to rotate and also need to be able to lift up and down, so the structure of the hose cup holder is still complicated, and a benchmarking device requires multiple such hose cup holders, so the overall manufacturing cost is high

In addition, the up and down movement of the hose cup will cause wear to the internal bearings, which will deteriorate the rotation synchronization of the hose cup and shorten the service life of the hose cup

[0012] 2. The above-mentioned mechanism can only perform benchmarking operations. After the benchmarking operation is completed, it will be directly sealed. In this way, a large amount of air will be encapsulated in the hose, thereby greatly shortening the shelf life of the paste liquid in the hose

[0013] 3. The use of compression springs and conical hammers can initially position the hose, but the conical hammer cannot rotate with the rotation of the hose. Produces greater rotational resistance and increases the rotational power of the motor
