Description

Technical Field

[0001] The invention relates to the field of plastic sealing machines, and in particular to a screw element plastic sealing machine. Background Art

[0002] The threaded component sealing machine is a special machine for the industry. It can wrap a layer of medium on the outer surface of the threaded component to improve the protection ability of the threaded component. Different from the conventional sealing medium, the sealing medium used by the threaded component sealing machine is a hot-melt peelable plastic. The sealing medium cannot directly contact the heating equipment and needs to be isolated and heated for liquefaction. Therefore, the sealing process of the threaded file is mostly to immerse the threaded component into the liquefied medium through the basket, and then lift it through the lifting mechanism. After cooling and solidification, a layer of protective medium is wrapped around the outer layer of the threaded component. According to user feedback, because the basket needs to be immersed in the medium, in most cases, the movement rate of the basket will be appropriately slowed down to prevent medium splashing, but after the rate is lowered, the threaded components in the basket are subjected to less impact force, so there is little position movement, and the basket has no other structure to drive the threaded components. Therefore, there is a certain probability that the area where adjacent threaded components always keep in contact will have a blind spot of sealing, and the sealing quality is not high. Based on this, it is necessary to propose an improved threaded component sealing machine based on the above description. Summary of the invention

[0003] The purpose of the present invention is to provide a threaded component sealing machine to solve the above technical problems.

[0015] The slider is slidably matched with the slide groove;

[0016] The soft rod is located in the interlayer, and the end of the soft rod is fixedly combined with a sliding block arranged in the sliding groove;

[0017] When the frame structure moves to the bottom of the second groove through the lifting part, the soft rod contacts the bottom of the second groove before the frame structure, so that the soft rod connected to the slider forms a V-shaped support part in the frame structure, guiding the threaded element to gather in the middle;

[0018] Alternatively, the frame structure moves upward from the bottom of the second groove via the lifting portion, so that the slider extends downward from the open slot, and the V-shaped support portion formed in the frame structure is dragged into a straight structure and hidden in the interlayer.

[0019] Preferably, the slider has a soft rod groove, which is the connection between the slider and the soft rod. The soft rod groove and the bottom plate also form a space for accommodating the soft rod when the soft rod extends outwardly relative to the open slot.

[0020] Preferably, the lifting part includes a cylinder, a centering shaft and an axle seat arranged in the frame, wherein there are two centering shafts, one of which is connected to the cylinder, and the axle seat is used to constrain the moving direction of the centering shaft.

[0021] Preferably, the lifting part further comprises two pull rods connected to the frame structure, wherein each pull rod is provided with a lifting shaft, and the lifting shaft is connected to the corresponding centering shaft.
