The structure of the previously known packaging machine packing device is mainly as shown in the first and second figures, and mainly includes a filling pipe 1 composed of a communicating feeding pipe portion 11 and a filling pipe pipe portion 12, and a feeding pipe portion. 11 is disposed at a slightly upper ventral side of the filling tube portion 12, and a leak-proof rod 2 having a small outer diameter is disposed in the tube portion of the filling tube portion 12, and the lower end of the leak-proof rod 2 is provided at the lower end An inclined diameter portion 21 corresponding to the inner diameter of the tube filling the tube portion 12, and a filling portion 13 having a tapered shape corresponding to the tapered portion 21 at the lower end of the filling tube portion 12 is provided. The tapered portion 21 and the filling port 13 may be in close contact with each other; and a flow chamber 14 having an expanded shape is provided on the ventral side of the filling tube portion 12 slightly above the filling opening 13.

In addition, the upper end of the filling tube portion 12 is coupled with a screw joint 15 for allowing the upper end of the leakage preventing rod 2 to pass through, and a base 31 is coupled to the screw joint 15 and mounted on the base 31. A pneumatic cylinder 32 having an actuating lever 321 is provided, and a cap 33 for allowing the leakage preventing rod 2 to be worn out is screwed onto the screw joint 15, and then between the upper end of the screw joint 15 and the inside of the cap 33. A leak-proof unit 4 is installed, and the leak-proof unit 4 further includes a guide 41 for the slip-proof rod 2 to be guided and guided, and the lower end of the guide 41 is provided with an insertable screw joint 15 and sleeved. The insertion portion 411 of the sealing washer 42 has a liner 43 for guiding the sliding of the leakage preventing rod 2 at the upper end of the reversing guide 41, and is respectively sleeved on the leakage preventing rod 2 at both ends of the liner 43 A sealing washer 44 is provided; finally, after the upper end of the leakage preventing rod 2 is worn out of the cap 33, a connecting member 34 is connected between the upper end of the leakage preventing rod 2 and the actuating rod 321 of the pneumatic cylinder 32.

Therefore, as shown in the third figure, when the pneumatic cylinder 32 drives the stop rod 2 to move upward, the tapered portion 21 at the lower end of the stop rod 2 will retreat from the filling port 13 to the flow chamber 14, so The liquid or powder or particles to be filled can enter the filling tube portion 12 along the feeding tube portion 11, and then flow out from the filling port 13 by the bypass chamber 14 over the inclined taper portion 21 to perform the filling operation; On the contrary, when the pneumatic cylinder 32 drives the leakage preventing rod 2 to move downward, the tapered tapered portion 21 at the lower end of the leakage preventing rod 2 is in close contact with the filling opening 13, thereby preventing the flow of the material in the tube filling the tube portion 12.

Therefore, whether the filling operation of the filling of the liquid or the powder or the granules is carried out, as soon as the amount to be filled is reached, the filling port 13 can be immediately closed, and the continuous outflow of the filling material is completely blocked, so that continuous During the filling operation, the problem of unnecessary filling of the filling can be completely avoided; at the same time, after the filling operation is completed, or when it is finished, especially the inside of the filling tube portion 12, the appearance of the leakage preventing rod 2, and others may also Parts such as the leak-proof unit 4 that will remain or adhere to the filling must be thoroughly cleaned to keep the packing device clean and hygienic, so that the next filling operation can be carried out smoothly.

As shown, the connecting member 34 connected between the leakage preventing rod 2 and the pneumatic cylinder 32 must first be disassembled, so that the leakage preventing rod 2, the leakage preventing unit 4, etc. can be started after the cap 33 is loosened. The parts are taken out from the filling tube portion 12 and the screw joint 15, and the cleaning operation of the above parts can be performed first; and after the cleaning is completed, the above-mentioned parts and components are assembled back, but the originally calibrated pneumatic cylinder 32 The center distance between the stop rod 2 and the stop rod 2 must be recalibrated. Otherwise, the deflection of the driving force will be caused, which will hinder the displacement of the stop rod 2 in the upper and lower portions of the filling tube portion 12, and it is easy to prevent The components of the leak unit 4 are worn out, the life is shortened, and the leakage problem often occurs. At the same time, because the center distance between the pneumatic cylinder 32 and the stop rod 2 is inaccurate, the deflection of the driving force is caused, Long time, it is easy to cause the leakage of the stop rod 2, which will affect the smoothness of the operation and the service life.

Therefore, after the components of the packing device are cleaned and assembled, it is necessary to perform multiple actuation tests and re-assembly to the desired state, and then the formal filling and packaging operation can be performed, which makes the assembly after cleaning very troublesome and difficult. .

In order to improve the disassembly of the filling device to be cleaned after the filling tube portion and the screw joint portion of the known packing device are welded and fixed together, it is troublesome, and at the same time, the assembly is returned. It is difficult to calibrate the center distance between the pneumatic cylinder and the leakage preventing rod. Therefore, the present invention provides a screw joint that can accommodate a leak stopping unit and can guide the leakage preventing rod, and is directly disposed at the upper end of the filling tube portion. After the sleeve is put on the base and then screwed by the cap, the filling tube can be fixed on the base; otherwise, the cap can be loosened without disassembling the connection between the leaking rod and the pneumatic cylinder. The filling pipe can be retracted for cleaning of each part, and when the cleaning is completed and the assembly is reversed, the center distance between the leakage preventing rod and the pneumatic cylinder is not changed, so that the leakage preventing rod and the filling tube are kept on the same center line, so that Assembly is easier.

The technical solution adopted by the present invention to solve the technical problem is that a base of a filling pipe is connected to a base on which a pneumatic cylinder is fixed, and the two ends of the connecting piece are respectively connected to the pneumatic cylinder and one of the filling filling pipes.
