[0024] The utility model provides a kind of deviation rectifying device of belt 11, as shown in the drawings, Figures 1 to 3 The first mechanism and the second mechanism are sequentially arranged along the running direction of the belt 11. The belt 11 in the embodiment is a hard Teflon high-temperature-resistant belt, and the belt 11 is arranged between the two side plates 12. Rollers 13 are further arranged between the two side plates 12, respectively. The two ends of the roller 13 are embedded in bearings, and the roller 13 penetrates the transmission shaft. After the transmission shaft penetrates the roller 13 and penetrates the two bearings, the two ends of the transmission shaft are fixed to the two side plates 12, respectively, so as to limit the roller 13 to rotate only between the two side plates 12, and one of the rollers 13 is driven by the motor 14. When the motor 14 drives the roller 13 to rotate, the belt 11 can be driven to run.

[0025] An upper end between the two side plates 12 can further be provided with a sealing plate 15. By screwing the screw outward from the side surface of the two side plates 12 to the sealing plate 15, the sealing plate 15 can be fixed between the two side plates 12, and the sealing plate 15 covers the belt 11 above, playing a protective role.

[0026] As shown in the drawings, Figure 5 and 6 The first mechanism 2 includes a connecting pin 21 and a limiting sleeve 22. The two ends of the connecting pin 21 are fixed to the side plates 12 arranged on the two sides of the belt 11, respectively, and the two ends of the connecting pin 21 are embedded with the limiting sleeve 22, so that the limiting sleeve 22 moves and rotates relative to the connecting pin 21. One end of the limiting sleeve 22 is provided with a protruding limiting portion 221, and the side of the limiting portion 221 facing the axial middle of the limiting sleeve 22 is an inclined guide surface 222. The limiting sleeves 22 at the two ends of the connecting pin 21 are mirror-symmetrically arranged, so that the guide surfaces 222 of the two limiting sleeves 22 are both directed to the middle of the connecting pin 21.

[0027] Continuing to refer to the drawings Figure 5 And 6 One side of the belt 11 runs above or below the two limiting sleeves 22, and the belt 11 is located between the limiting portions 221 of the two limiting sleeves. In this embodiment, the first mechanism 2 is arranged above the belt 11, so that the bottom surface of the belt 11 can form a complete plane, which is used to press the cloth in a seamless hot press, and the cloth is moved by the running of the belt 11. During the normal running of the belt 11, when the belt 11 is not deviated, the belt 11 moves between the two limiting sleeves 22 and does not contact the two limiting sleeves 22. When the belt 11 is deviated on one side, the belt 11 leans against the guide surface 222 of the limiting sleeve 22 on the deviated side, so that the other side of the belt 11 is pressed against the other limiting sleeve 22, and the limiting sleeve 22 is rotated by the frictional force of the running belt 11, and the rotating limiting sleeve 22 drives the belt 11 to move to the other side, so as to correct the running direction of the belt 11.

[0028] With the drawings Figure 6 For example, when the belt 11 deviates to the left and pushes against the guide surface 222 of the left limiting sleeve 22, the left side of the belt 11 moves to the guide surface 222, so that the part of the belt under the first mechanism is inclined, and the right side of the belt 11 is pressed upward against the right limiting sleeve 22. The pressure of the belt 11 pressing against the right limiting sleeve 22 drives the right limiting sleeve 22 to rotate, and at this time, the right limiting sleeve 22 is blocked by the belt 11 and cannot move to the left, and at the same time, the belt 11 slides to the middle between the two side plates 12 under the blocking of the guide surface 222 of the left limiting sleeve 22, that is, the right limiting sleeve 22 drives the belt 11 to move to the right at the same time, so as to pull the belt 11 to the right, and correct the deviation of the belt 11.

[0029] As shown in the drawings Figure 3 And 4 The second mechanism 3 includes a first blocking rod 31 and a second blocking rod 32, both ends of the first blocking rod 31 and both ends of the second blocking rod 32 are fixed on the two side plates 12, and the belt 11 runs through the first blocking rod 31 and the second blocking rod 32. For example, the belt 11 passes above the first blocking rod 31, then passes between the first blocking rod 31 and the second blocking rod 32, and then passes below the second blocking rod 32. In this structure, the frictional resistance of the belt 11 during running is increased by the first blocking rod 31 and the second blocking rod 32, and during the running of the belt 11 driven by the roller shaft 13, it is equivalent that one end of the belt 11 is pulled by the first blocking rod 31 and the second blocking rod 32, and the other end of the belt 11 is pulled forward by the roller shaft 13, so that the belt 11 is straightened, and thus the belt 11 is straightened and corrected.

[0030] Further, preferably, the device of the utility model also can include third mechanism arranged in one end of the roller shaft 13 not driven by the motor 14, and the end of the two side plates 12 are all provided with third mechanism. Figure 7 As shown in the figure, the third mechanism includes adjusting screw 41, one end of the side plate 12 side is provided with through strip hole 121, the adjusting screw 41 is inserted into the strip hole 121 from the end surface of the side plate 12, and the adjusting screw 41 is limited to only rotate, and the limiting mode can be connected by the fixed plate 42 fixed in the strip hole 121, specifically, the fixed plate 42 is provided with connecting hole, the adjusting screw 41 is fixed after passing through the connecting hole, and the limiting piece (not shown in the figure) is fixed, the outer diameter of the limiting piece is greater than the hole diameter of the connecting hole, and the limiting piece can be the snap spring assembled on the adjusting screw 41, so that the one end of the adjusting screw 41 is limited between the fixed plate 42 and the side wall away from the end of the side plate 12, so that the adjusting screw 41 is limited to not pull out of the strip hole 121 and only rotates.

[0031] The transmission shaft 131 of the roller shaft 13 not driven by the motor 14 is respectively connected with the adjusting screw 41 inserted into the two side plates 12 in screw connection. In the structure of the above third mechanism, the one end of the roller shaft 13 not driven by the motor 14 can be moved to the end of the side plate 12 or moved to the middle of the side plate 12 by rotating the adjusting screw 41, so as to drive the one end of the roller shaft 13 to move. When the two ends of the roller shaft 13 are simultaneously moved to the outside of the side plate 12 or to the inside of the side plate 12, the roller shaft 13 is driven to move inward or outward, so as to realize the adjustment of the tightness degree of the belt 11; when the two moving pieces are adjusted to the inclination of the roller shaft 13 relative to the side plate 12, the inclination degree of the originally inclined belt 11 can also be adjusted.

[0032] In summary, the first mechanism 2 and the second mechanism 3 of the utility model are sequentially arranged along the running direction of the belt 11, so that the belt 11 is first corrected by the two limiting sleeves 22 of the first mechanism 2 in the running process, then passes through the first stop lever 31 and the second stop lever 32, and the friction resistance formed by the first stop lever 31 and the second stop lever 32 to the belt 11 can restrain the belt 11, so that the roller shaft 13 can straighten the belt 11 when pulling the belt 11 forward, thereby realizing the straightening and correction of the belt 11, finally forming two mechanisms for correcting the belt 11, so that the belt 11 can run straight between the two side plates 12, avoiding the deviation of the belt 11 to the side edge and unable to run smoothly.

[0033] The above is only the specific implementation manner of the utility model, but the design concept of the utility model is not limited to this, and any non-essential change of the utility model by using the concept should belong to the behavior of infringing the protection range of the utility model.
