[0024] like Figures 1 to 5 As shown, a drawing machine for strapping tape comprises a drawing machine body 13, and a plurality of drawing rollers installed on one side of the drawing machine body 13, wherein the drawing rollers are divided into an upper drawing roller 10 and a lower drawing roller 11, and the upper drawing roller 10 and the lower drawing roller 11 are sealed and connected;

[0025] A rotating shaft 1 is rotatably connected inside the stretching machine body 13, and a disc 2 is detachably connected to the rotating shaft 1 on the side close to the stretching roller. Two limit rods 3 are detachably connected to the side of the disc 2 close to the stretching roller. The two ends of the limit rod 3 extend into the upper stretching roller 10 and the lower stretching roller 11 respectively and slide with them; the cross-sectional shape of the limit rod 3 is set to be U-shaped, and two fixed blocks 5 are set on the side of the upper stretching roller 10 and the lower stretching roller 11 away from the disc 2, and the stretching roller is fixed by the engagement between the fixed block 5 and the limit rod 3.

[0026] Two grooves 9 are provided on the side of the upper drafting roller 10 and the lower drafting roller 11 away from the disc 2. A telescopic rod 6 and a spring 7 are arranged in the groove 9. The spring 7 is sleeved on the outside of the telescopic rod 6, and the two ends of the telescopic rod 6 and the spring 7 are respectively fixed to the inner wall of the drafting roller and the fixed block 5; a clamping groove 4 is provided on the side of the limit rod 3 close to the fixed block 5, and the limit rod 3 and the fixed block 5 are clamped together through the clamping groove 4.

[0027] When the upper and lower ends of the two limit rods 3 are fixed, the upper and lower ends of the two limit rods 3 are fixed, and the upper and lower end of the two limit rods 3 are fixed.

[0028] Two sealing strips 12 are detachably mounted on one side of the lower drafting roller 11, and two sealing grooves are provided on the side of the upper drafting roller 10 close to the lower drafting roller 11. The sealing strips 12 are matched with the sealing grooves, so that a sealing arrangement is formed between the lower drafting roller 11 and the upper drafting roller 10 to prevent leakage of the cooling liquid passed between the upper drafting roller 10 and the lower drafting roller 11.

[0029] At the same time, once the inner wall of the drafting roller needs to be cleaned, since the fixed block 5 is detachably connected to the side away from the disc 2 with a movable push rod 8, the movable push rod 8 extends to the outside of the drafting roller, and the movable push rod 8 can be pushed to move in the direction away from the limit rod 3. The movable push rod 8 can also drive the fixed block 5 to move while moving, and the fixed block 5 is moved to release the fixation between the limit rod 3 and the fixed block 5. At this time, the upper drafting roller 10 or the lower drafting roller 11 can be removed to facilitate cleaning of impurities in the upper drafting roller 10 and the lower drafting roller 11. The cleaning is convenient and the operation is simple. A cover net 15 is hinged on the outside of the drafting machine body 13 to protect the drafting roller.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
