Down filling machine down filling pipe mechanism with down filling depth adjusting function

Abstract

The invention discloses a down filling machine down filling pipe mechanism with a down filling depth adjusting function, and belongs to the technical field of down filling equipment. The down filling machine down filling pipe mechanism comprises a down filling outer pipe and a down filling inner pipe, the down filling inner pipe is slidably inserted into an inner cavity of the down filling outer pipe, and a threaded sleeve is rotatably mounted on the outer wall of the right side of the down filling outer pipe; the threaded sleeve is arranged on the outer wall of the down filling inner pipe in a sleeving mode, a placing groove is formed in the left end of the down filling inner pipe, an adjusting device is arranged in an inner cavity of the placing groove, in the device, a guide block is pulled rightwards, a pull rod pulls two sets of piston plates rightwards to move rightwards, air in an annular groove is drawn into an air storage groove, and the air pressure in the annular groove is reduced; a sealing ring is shrunk, the contact pressure between the sealing ring and the inner wall of the down filling outer pipe is reduced or the sealing ring does not make contact with the inner wall of the down filling outer pipe, the probability of friction between the down filling outer pipe and the sealing ring is reduced in the moving and adjusting process of the down filling outer pipe, the probability of abrasion of the sealing ring is reduced, and the probability of bending deformation of the sealing ring due to contact friction is also reduced.

Description

technical field [0001] The invention relates to the technical field of down filling equipment, in particular to a down filling tube mechanism for a down filling machine with the function of adjusting the down filling depth. Background technique [0002] When filling toys or clothing, a down filling machine is used. Generally, the object to be filled is placed on the down filling tube of the down filling machine, and the inside of the object is filled with down through the down filling tube. The convenience of using the down machine makes the down filling machine suitable for down filling processing of different depths. The existing down filling tube is generally composed of an outer tube and an inner tube. The outer tube is set on the outer wall of the inner tube, and the inner tube can be Slide on the outer wall of the down filling tube, so that the overall length of the down filling tube can be adjusted. However, in order to ensure the tightness of the down filling tube, a...

[0002] When filling toys or clothing, a down filling machine is used. Generally, the object to be filled is placed on the down filling tube of the down filling machine, and the inside of the object is filled with down through the down filling tube. The convenience of using the down machine makes the down filling machine suitable for down filling processing of different depths. The existing down filling tube is generally composed of an outer tube and an inner tube. The outer tube is set on the outer wall of the inner tube, and the inner tube can be Slide on the outer wall of the down filling tube, so that the overall length of the down filling tube can be adjusted. However, in order to ensure the tightness of the down filling tube, a sealing ring needs to be installed between the outer tube and the inner tube. When adjusting the length of the down filling tube, due to the sealing ring It will fit closely with the inner wall of the outer tube, which will cause greater pressure between the sealing ring and the inner wall of the outer tube. When the outer tube slides on the outer wall of the inner tube, the sealing ring will be easily worn, and it will also easily cause the sealing ring to be damaged Sliding and bending or deformation will cause the sealing ring and the outer tube to be unable to fit tightly. During the down filling process, there will be a certain pressure inside the down filling tube. Because the seal is not tight, the air pressure inside the down filling tube will be weakened, which will affect the down filling work. , and it is also easy to cause the down to pass through the down filling tube, which will cause waste of resources. Therefore, we propose a down filling tube mechanism for a down filling machine with an adjustable function of down filling depth
