Referring to fig. 1 and 2, the utility model discloses a polyethylene gas pipe die cleaning tool of an embodiment for wash the bush of extruder, it includes device main part 100, is provided with rotatable brush utensil installation department 101 on the device main part 100, and the end of brush utensil installation department 101 is provided with wears groove 105, wears the inslot 105 and detachably installs cleaning brush 102.

When the polyethylene gas pipe die cleaning tool is adopted, a user only needs to move the cleaning brush 102 in the neck mold, so that the interior of the neck mold can be cleaned, and the tool is efficient and labor-saving.

To facilitate the production and the assembly and disassembly of the cleaning brush 102, in some embodiments of the present invention, the length of the through groove 105 is the same as the rotation axis direction of the brush mounting portion 101, and the end opening of the through groove 105 is arranged, so that two holding arms 104 are formed at the tail portion of the brush mounting portion 101. This allows the cleaning brush 102 to be directly loaded into and unloaded from the end of the through-groove 105, and the through-groove 105 of this structure is also more easily processed, while the closer the two gripper arms 104 are to the end of the apparatus body 100, the more easily the cleaning brush 102 is gripped.

In some embodiments, the proximal ends of the two gripping arms 104 are provided with corresponding reliefs. The clamping force of the cleaning brush 102 is improved by the matching of the concave-convex structures. The specific shape of the concave-convex structure can be saw-toothed, wave-shaped and the like.

In order to further enhance the installation stability of the cleaning brush 102, in some embodiments of the present invention, a positioning screw is disposed on the brush installation portion 101 and traverses the through groove 105, and a positioning hole is disposed on the cleaning brush 102 corresponding to the positioning screw. Thus, when the cleaning brush 102 is installed in the through groove 105, the positioning screw is installed again, so that the cleaning brush 102 is locked and prevented from falling off and loosening along with the rotation of the brush installation part 101.

And in order to satisfy the effect that cleaning brush 102 cleaned the mouth mould, the utility model provides a dimension of brush utensil installation department 101 is less than the bore of bush to can stretch into certain length in the bush. As shown in the drawings, the brush attachment portion 101 preferably has a round bar structure.

In some embodiments of the present invention, a driving mechanism is provided in the device main body 100, the driving mechanism is provided with an output shaft, and the brush attachment portion 101 is detachably attached to the end of the output shaft. Specifically, in an embodiment, the driving mechanism is further provided with a driving motor and a transmission gear set, and the driving motor controls the output shaft to rotate through the transmission gear set. Therefore, the speed is reduced through the transmission gear set, and the cleaning brush 102 is driven to rotate, so that stable transmission is facilitated.

In some embodiments, the end of the output shaft is provided with a drill chuck 103, and the brush mounting portion 101 is of a rod-like configuration and is removably mounted to the drill chuck 103. The structure of the drill chuck 103 is similar to the structure of the drill chuck 103 of the electric drilling machine on the market, so that the description is not excessive. Through the setting of drill chuck 103, can realize dismantling fast of brush utensil installation department 101 and trade, can set up two centre gripping arms 104 in brush utensil installation department 101 and carry out the installation of cleaning brush 102, change when centre gripping arm 104 is out of order.

In some embodiments, the cleaning brush 102 includes a support plate capable of elastically deforming and bending and a steel sponge layer covering the support plate. The structure of the steel wire sponge layer is similar to that of the steel wire sponge cloth on the market, and therefore, will not be described herein. Because the steel wire sponge layer is relatively soft, a supporting plate is arranged in the steel wire sponge layer, so that the cleaning brush 102 can not only ensure certain contact strength but also not scratch the inner wall of the neck mold when contacting the inner wall of the neck mold. The support plate is preferably made of a polymer material.

As shown, in some embodiments, the support plate is provided with a rib along a direction perpendicular to the rotation axis of the brush attachment portion 101. Because the supporting plate is forced to bend along the direction perpendicular to the rotating shaft of the brush mounting part 101 when the cleaning brush 102 is used for cleaning, the arrangement of the reinforcing ribs can effectively improve the strength and toughness of the supporting plate and prolong the service life.

Further, in some embodiments, a hand-held portion is provided on the device body 100 for easy handling.

In the description herein, references to the description of the term "one embodiment," "some embodiments," "an illustrative embodiment," "an example," "a specific example," or "some examples" or the like mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
