Description

Technical Field

[0001] The utility model relates to the field of installation of drawing rollers, and particularly relates to an installation structure of a drawing roller for plastic packing belts. Background Art

[0002] Plastic packing belts are generally formed by extrusion. After extrusion, in order to shape the plastic packing belts, the plastic packing belts usually need to be shaped through a drawing roller. The drawing roller for packing belts is an important component in the process of shaping the packing belts. In actual use, according to the production requirements of different projects, drawing rollers of different sizes need to be replaced. After removing the original drawing roller, a drawing roller with dimensions meeting the production requirements of the packing belts is reinstalled.

[0003] In the prior art for installing a drawing roller, generally, the upper and lower parts of a flange are respectively fixed to the drawing roller and a cooling pipe, and then the two parts of the flange are fixed together by bolts to connect the drawing roller and the cooling pipe. However, in actual operation, there are the following problems. During installation, the threaded holes on the upper and lower parts of the flange are not completely accurately aligned. If the positions of the threaded holes of these two parts need to be adjusted, the drawing roller often needs to be rotated together. However, the drawing roller itself is heavy and it is inconvenient to move.

[0004] Therefore, it is necessary to provide an installation structure of a drawing roller for plastic packing belts to solve the above technical problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an installation structure of a drawing roller for plastic packing belts to solve the problems in the prior art that during installation, the threaded holes on the upper and lower parts of the flange are not completely accurately aligned, and if the positions of the threaded holes of these two parts need to be adjusted, the drawing roller often needs to be rotated together, and the drawing roller itself is heavy and it is inconvenient to move.

[0006] Based on the above idea, the utility model provides the following technical solution: It includes a drafting machine body, a plurality of drawing roller bodies arranged on the drafting machine body, and a cooling pipe. The outer side of the drawing roller body is detachably connected with an upper flange, one end of the cooling pipe is detachably connected with a lower flange on the outer side, a rotatable annular disc is arranged inside the lower flange, a plurality of threaded holes are formed on both the annular disc and the upper flange, and an annular groove is formed between the upper surface of the lower flange and the upper surface of the annular disc;

[0007] A sealing groove is formed on the upper surface of the upper flange, and a sealing strip is detachably connected to the lower surface of the upper flange. The sealing strip is arranged in the sealing groove and is in sealing cooperation with it;

[0008] A receiving cavity is formed on the lower surface of the annular disc, and a moving component is arranged inside the receiving cavity.

[0026] As Figures 1 to 4 shown, a plastic strapping draw roll installation structure includes a drafting machine body 16, a plurality of draw roll bodies 15 arranged on the drafting machine body 16, and a cooling pipeline 14. The outer side of the draw roll body 15 is detachably connected with an upper flange 4, one end of the cooling pipeline 14 is detachably connected with a lower flange 1 on the outer side, a rotatable annular disk 2 is arranged inside the lower flange 1, a plurality of threaded holes 3 are formed on both the annular disk 2 and the upper flange 4, an annular groove 6 is formed between the upper surface of the lower flange 1 and the upper surface of the annular disk 2. The setting of the annular groove 6 can reserve a certain gap between the lower flange 1 and the upper flange 4 to facilitate the rotation of the annular disk 2; a sealing groove 8 is formed on the upper surface of the upper flange 4, a sealing strip 7 is detachably connected to the lower surface of the upper flange 4, and the sealing strip 7 is arranged in the sealing groove 8 and is in sealing cooperation with it; a receiving cavity is formed on the lower surface of the annular disk 2, and a moving component is arranged inside the receiving cavity.

[0027] One end of the draw roll body 15 penetrates through the drafting machine body 16 and extends to the other side of the drafting machine body 16, the cooling pipeline 14 is arranged on the side of the drafting machine body 16 far from the draw roll body 15, and the cooling pipeline 14 is detachably connected with the drafting machine body 16.

[0028] During specific operation, install the upper flange 4 on the outer side of one end of the drawing roll body 15. Then insert one end of the drawing roll body 15 into the hole reserved in the drafting machine body 16, and one end of the drawing roll body 15 extends to the other side of the drafting machine body 16. At the same time, install the lower flange 1 on the outer side of one end of the cooling pipe 14, and snap the lower flange 1 and the upper flange 4 together. At this time, the sealing strip 7 installed on the lower surface of the upper flange 4 just fits into the sealing groove 8, which can prevent the liquid introduced from the cooling pipe 14 into the drawing roll body 15 from leaking during transportation. By pulling the moving component in a direction away from the lower flange 1, the moving component can be moved from the accommodation cavity to the outside of the accommodation cavity. Then, by pushing the moving component to make a circular motion, the annular disk 2 rotates while the moving component rotates, so that the threaded holes 3 on the annular disk 2 and the upper flange 4 can be aligned, facilitating the fixation between the lower flange 1 and the upper flange 4 through the bolt 13. The size of the bolt 13 is adapted to the threaded hole 3. By rotating the annular disk 2, the threaded holes 3 on the lower flange 1 and the upper flange 4 can be quickly aligned without simultaneously moving the drawing roll body 15 or the cooling pipe 14, saving manpower.

[0029] As Figures 2 to 3 shown, installation grooves 9 are provided in both the lower flange 1 and the upper flange 4. The size of one installation groove 9 is adapted to the outer diameter of one end of the drawing roll body 15, and the size of the other installation groove 9 is adapted to the outer diameter of one end of the cooling pipe 14.

[0030] As Figure 5 shown, the moving component includes a push rod 10. The push rod 10 is arranged in the accommodation cavity, and tooth teeth are provided on both sides of the push rod 10; the limiting tooth teeth 11 are detachably connected to the inner walls on both sides of the accommodation cavity, and the tooth teeth mesh with the limiting tooth teeth 11.

[0031] A pull ring 12 is detachably connected to the side of the push rod 10 away from the annular disk 2, and the pull ring 12 is located in the accommodation cavity.

[0032] During specific operation, by pulling the pull ring 12 in a direction away from the annular disk 2, the moving component is moved to the outside of the accommodation cavity. The specific operation is as follows: the movement of the pull ring 12 can drive the movement of the push rod 10, and the movement of the push rod 10 drives the tooth teeth on both sides of the push rod 10 to move simultaneously. Under the action of the limiting tooth teeth 11 meshing with them, the push rod 10 can be prevented from directly moving from the accommodation cavity to the outside of the accommodation cavity due to gravity. When the push rod 10 is needed, by pulling the pull ring 12, the push rod 10 can be driven to move in a direction away from the annular disk 2, and one end of the push rod 10 can be pulled out of the accommodation groove. Then, by pushing the push rod 10, the annular disk 2 can be driven to rotate, so as to quickly align the threaded holes 3 on the lower flange 1 and the upper flange 4.
