DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 The present embodiment provides a cloth conveying tension adjustment mechanism, comprising a drying box 1, a guide mechanism 2 installed in the drying box 1, a support platform 3 installed on one side of the drying box 1, and a pre-tightening mechanism 4 installed on the support platform 3. The cloth to be dried first passes through the pre-tightening mechanism 4 on one side, and then enters the drying box 1, and is dried in the drying box 1, wherein the guide mechanism 2 in the drying box 1 supports and guides the cloth, and assists in drying the cloth.

[0023] See also Figure 1 and Figure 2 , wherein an inlet 7 and an outlet 8 are provided on opposite sides of the drying box 1, and the cloth enters the drying box 1 from the inlet 7 and exits from the outlet 8. In order to reduce the excessive friction of the cloth at the inlet 7 and the outlet 8, a first guide roller 9 is rotatably installed at the inlet 7, and a second guide roller 10 is rotatably installed at the outlet 8. Through the guide rollers, the sliding friction between the cloth and the inner wall of the inlet 7 or the outlet 8 is converted into the rotational friction between the cloth and the first guide roller 9 or the second guide roller 10, thereby reducing the friction damage of the cloth.

[0024] During the drying process, when drying thicker cloth, since the surface of the cloth is thicker and the water content per unit area of ​​the cloth is larger, the water evaporation time is longer, and the cloth conveying speed needs to be slowed down to facilitate thorough drying. However, this can easily slow down the drying efficiency and increase energy consumption. At the same time, when drying thinner cloth, the water evaporates faster, and it is necessary to reduce the residence time of the cloth in the drying box 1, otherwise the cloth fiber will be easily damaged and cracked.

[0025] See also Figure 1 and Figure 2In order to solve the above technical problems, the guide mechanism 2 includes a plurality of guide cylinders 21 arranged along the length direction of the drying box 1, and the guide cylinders 21 include an upper guide cylinder 23 and a lower guide cylinder 24. In the horizontal direction, the upper guide cylinders 23 and the lower guide cylinders 24 are staggered. A driving member 22 for driving the guide cylinders 21 to move in the vertical direction is installed on the drying box 1. In the initial state, the upper guide cylinder is located on the upper side of the inlet 7 in the vertical direction, and the lower guide cylinder is located on the lower side of the inlet 7 in the vertical direction.

[0026] Generally, the drying box 1 is relatively long, and in order to facilitate the complete drying of the cloth, the guide cylinder 21 is required to support the cloth. The cloth is firstly introduced from the inlet 7, and then driven to move toward the outlet 8 by the traction unit, so that there is no need for manual traction in the drying box 1, which saves manpower. After the cloth passes through the drying box 1, the upper guide cylinder 23 is driven downward by the driving member 22, so that the lower side of the guide cylinder 21 contacts the cloth, and the cloth at the contact point is pushed downward. At the same time, the guide cylinder 24 moves upward under the driving of the driving member 22, and the upper side of the lower guide cylinder 24 contacts the cloth, and the cloth is pushed upward. Because the upper guide cylinder 23 and the lower guide cylinder 24 are staggered, the cloth is supported and the displacement of the cloth in the drying box 1 is increased. At the same time, the upper guide cylinder 23 contacts the upper side of the cloth, and the lower guide cylinder 24 contacts the lower side of the cloth. In order to adapt to the residence time of cloths of different thicknesses in the drying box 1, when the cloth is thicker, the lower guide cylinder 24 is driven downward by the driving member 22, or the lower guide cylinder 24 is driven upward by the driving member 22, thereby increasing the movement displacement of the cloth in the drying box 1, and then at the same movement speed, increasing the residence time of the cloth in the drying box 1, which is convenient for drying.

[0027] See also Figure 2 and Figure 3 The pre-tightening mechanism 4 includes a first support frame 41 fixedly mounted on the support platform 3, two clamping rollers 42 are rotatably mounted on the first support frame 41, a pressure roller 43 is arranged between the clamping roller 42 and the drying box 1, and a driving unit 44 is installed on the support platform 3.

[0028] The cloth passes between the two clamping rollers 42, then bypasses the pressing roller 43 and enters the drying box 1, and is rolled up by the winding mechanism, wherein the cloth is clamped and rubbed by the two clamping rollers 42 to provide a pre-tightening force to the cloth, so that the cloth is in a straight state in the drying box 1, and then the pressing roller 43 is lowered to make the lower side of the pressing roller 43 contact the upper side of the cloth. At this time, the driving unit 44 does not exert force on the pressing roller 43, so that the pressing roller 43 presses down the cloth between the clamping roller 42 and the drying box 1 under the action of its own gravity, so that the cloth is subjected to the tension of the winding mechanism and the pressure from the pressing roller 43 from top to bottom;

[0029] Due to the difference in drying effects, it is necessary to fine-tune the time the cloth stays in the drying box 1, that is, to adjust the position of the guide cylinder 21. When reducing the time the cloth stays in the drying box 1, it is necessary to move the guide cylinder 21 to the middle of the drying box 1, so that there is a gap between the guide cylinder 21 and the cloth. When the winding mechanism pulls the cloth, the cloth is prone to wrinkles and folds during movement due to excessive speed and excessive gap. Therefore, when a gap appears between the guide cylinder 21 and the cloth, the pressure roller 43 will push the cloth between the drying box 1 and the clamping roller 42 to move downward under the action of the gravity of the pressure roller 43. Because the friction between the clamping roller 42 and the cloth is greater than the gravity of the pressure roller 43, the pressure roller 43 will drive the contacted cloth to move downward for a distance, and then the cloth in the drying box 1, that is, the cloth with a gap from the guide cylinder 21, will contact the guide cylinder 21 under the pressure of the pressure roller 43, so that when the height of the guide cylinder 21 is adjusted, the cloth is still in close contact with the guide cylinder 21, thereby reducing the wrinkles and folds of the cloth when the cloth moves due to the adjustment of the guide cylinder 21.

[0030] See also Figure 4 and Figure 5 The driving unit 44 includes two second support frames 45 fixedly mounted on the support platform 3, and the two second support frames 45 are respectively located on both sides of the pressure roller 43. A winding piece 46 is rotatably mounted on each second support frame 45, and a reel is mounted inside the winding piece 46. A shaft 47 is commonly fixedly mounted at the axis of the two reels. A motor 48 for driving the shaft 47 to rotate is mounted on the second support frame 45, and a pull rope 49 is wound around the surface of the reel, and the lower side of the pull rope 49 is connected to the pressure roller 43.

[0031] In the initial state, the drawstring 49 is wound around the winch, and the drawstring 49 pulls the pressure roller 43 close to the upper side of the second support frame 45. The fabric first passes between the two clamping rollers 42, then passes through the lower side of the current pressure roller 43, and then passes through the drying box 1. The motor 48 drives the shaft 47 to rotate, and then drives the winch to rotate, so that the drawstring 49 is released from the winch, and then the pressure roller 43 is gradually lowered, so that the pressure roller 43 contacts the upper side of the fabric, and then the winch continues to release the drawstring 49, so that the pressure roller 43 is completely pressed on the upper side of the fabric, and as the fabric loosens, the pressure roller 43 can also apply pressure to the fabric by its own gravity, and the drawstring 49 does not hinder the pressure roller 43 at all, so that when the fabric loosens, the fabric is pre-tightened in time by the pressure roller 43 to increase the fabric tension.

[0032] See also Figure 4 and Figure 5The second support frame 45 includes two relatively parallel vertical plates 451 and a horizontal plate 452 fixedly connected to the two vertical plates 451. A slide groove 453 is provided on each vertical plate 451. A limit block 454 is slidably arranged in the slide groove 453. A connecting block 455 is fixedly installed on the opposite surfaces of the two limit blocks 454. One side of the pressure roller 43 is connected to the connecting block 455. The end of the pull rope 49 away from the winding member 46 is installed on the connecting block 455. Under the interaction between the slide groove 453 and the limit block 454, the movement of the connecting block 455 is guided, and then the movement of the pressure roller 43 is guided, thereby improving the stability of the pressure roller 43 when moving.

[0033] The clamping roller 42 located at the lower side is at the same height as the first guide roller 9 at the inlet 7. Therefore, when the cloth passes through the two clamping rollers 42 and the inlet 7, the cloth is basically in a horizontal movement state, so when the pressing roller 43 moves downward, the length of the cloth that can be pressed by the pressing roller 43 will increase, that is, the pressing roller 43 can pull a longer length of cloth under the same displacement.

[0034] Due to the different thicknesses of the fabrics, the clamping strength of the two clamping rollers 42 on the fabrics is also different, and the pressure of the pressing roller 43 on the fabrics also needs to change according to the thickness of the fabrics.

[0035] See also Figure 4 and Figure 5 To solve the above technical problems. A placement box 5 with an upper opening is fixedly mounted on the two connecting blocks 455, and a counterweight 6 is installed in the placement box 5. By placing the counterweight 6 in the placement box 5, the counterweight 6, the placement box 5, the connecting block 455 and the pressure roller 43 provide pre-tightening pressure to the cloth, wherein the number of the counterweight 6 can be replaced, so as to adjust the pressure of the pressure roller 43 on the cloth.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
