[0023] like Figures 1 to 5 As shown, a winding roller adjustment mechanism for a cold water tank includes two symmetrically arranged lifting plates 2, which are slidably connected to the side walls of the cold water tank body 1. A group of rotatable positioning winding rollers 3 for positioning the strapping tape is installed on one side of one of the lifting plates 2, and a group of rotatable conveying winding rollers 4 for supporting the strapping tape is installed on the same side of the other lifting plate 2; a driving mechanism is provided on the other side of the two lifting plates 2.

[0024] In this embodiment, a group of positioning winding rollers 3 for positioning the strapping tape and a group of conveying winding rollers 4 for supporting the strapping tape are located on the same horizontal line, and in the working state, the positioning winding rollers 3 and the conveying winding rollers 4 are both submerged in the water in the cold water tank body 1. The positioning winding rollers 3 and the conveying winding rollers 4 arranged on the same horizontal line can increase the contact time between the strapping tape and the cooling water, so that the strapping tape passing through the positioning winding rollers 3 and the conveying winding rollers 4 can be effectively cooled;

[0025] When the strapping tape is in contact with the cooling water for a sufficient time, the driving mechanism drives the two lifting plates 2 to move back and forth synchronously, and the positioning winding roller 3 and the conveying winding roller 4 move together with the lifting plate 2 to adjust the tightness of the strapping tape to ensure product quality. Appropriate tightness can ensure that the strapping tape maintains a stable shape during the winding process, avoiding quality problems such as bulging, adhesion, and wrinkles. For example, when the strapping tape is wound too tightly, the thicker parts of the strapping tape will be superimposed together, which will cause edge thickness or bulging, affecting the quality of use; and when the strapping tape is wound too loosely, the strapping tape is prone to displacement, core pulling, and end wrinkles, which will also affect the appearance and use effect of the product. By adjusting the height of the positioning winding roller 3 and the conveying winding roller 4, adjusting the angle between the positioning winding roller 3, the conveying winding roller 4 and other winding rollers, and then changing the tightness of the winding roller, it can be ensured that the strapping tape can move smoothly during the winding process, avoiding jamming or slipping caused by improper tightness, which helps to reduce downtime and failure rate in the production process and improve production efficiency.

[0026] Before the strapping tape is wound, the positioning winding roller 3 and the conveying winding roller 4 are driven upward and away from the water surface by the driving mechanism in advance, so as to facilitate winding the strapping tape onto the surface of the positioning winding roller 3 and the conveying winding roller 4. At the same time, it can avoid the operator's hands being placed in cold water when installing the strapping tape in cold winter, causing discomfort to the operator.

[0027] The specific structure of the driving mechanism in this embodiment is that the driving mechanism includes a cylinder 5 and a traction mechanism 6. The output end of the cylinder 5 is connected to the traction mechanism 6. The two lifting plates 2 are connected through the traction mechanism 6. The traction mechanism 6 includes a downward traction component and an upward traction component. The downward traction component is arranged close to the cylinder 5, and the upward traction component is arranged away from the cylinder 5.

[0028] In this embodiment, the downward pulling component is driven by the cylinder 5 to pull the two lifting plates 2 downward synchronously, and the upward pulling component positions the lifting plate 2 away from the cylinder 5; the upward pulling component is driven by the cylinder 5 to pull the two lifting plates 2 upward synchronously, and the downward pulling component positions the lifting plate 2 close to the cylinder 5.

[0029] The specific structure of the downward traction component and the upward traction component in this embodiment is that the downward traction component includes a horizontal plate 601, the number of the horizontal plates 601 is set to two, and the horizontal plates 601 are fixed to the lifting plate 2; one of the horizontal plates 601 is connected to the output end of the cylinder 5, and the top of the horizontal plate 601 is fixedly connected to the first steel wire rope 602, and the other end of the first steel wire rope 602 is installed at the bottom end of the other horizontal plate 601 through the first fixed pulley 604 and the second fixed pulley 605.

[0030] The upward traction component includes a second steel wire rope 603, the number of the first fixed pulley 604 and the second fixed pulley 605 are both set to two, and the two first fixed pulleys 604 and the second fixed pulleys 605 are symmetrically arranged; the second steel wire rope 603 is fixedly connected to one end of the horizontal plate 601 close to the cylinder 5, and the second steel wire rope 603 passes through the second fixed pulley 605 and the first fixed pulley 604 and is installed at the top of another horizontal plate 601.

[0031] In this embodiment, the cylinder 5 is started to drive the transverse plate 601 to move downward. The transverse plate 601 moves downward to pull one end of the first steel wire rope 602 to move downward along with the transverse plate 601. The first steel wire rope 602 changes the direction of force after passing through the first fixed pulley 604 and the second fixed pulley 605 fixedly installed on the cold water tank body 1, and then pulls the transverse plate 601 away from the cylinder 5 to move downward synchronously. The synchronous downward movement of the two transverse plates 601 drives the two symmetrically arranged lifting plates 2 to move downward synchronously. A group of positioning winding rollers 3 and a group of conveying winding rollers 4 both move downward along with the two lifting plates 2, thereby changing the tension of the strapping tape.

[0032] At the same time, a second steel wire rope 603 is installed at the top of the horizontal plate 601 away from the cylinder 5. The second steel wire rope 603 is also tightened after passing through the first fixed pulley 604 and the second fixed pulley 605 to change the direction of the force, so that the horizontal plate 601 away from the cylinder 5 is limited by the tightening of the second steel wire rope 603, so that the horizontal plate 601 away from the cylinder 5 can maintain this height and ensure the stability of the lifting plate 2;

[0033] When the cylinder 5 drives the first steel wire rope 602 to move upward, the horizontal plate 601 moves upward according to the same working principle, driving the second steel wire rope 603 to pull the horizontal plate 601 away from the cylinder 5 to move upward. At this time, the horizontal plate 601 is tightened by the first steel wire rope 602 to ensure the stability of the lifting plate 2 away from the cylinder 5.

[0034] Furthermore, through holes 606 are provided on both transverse plates 601, and the first steel wire rope 602 and the second steel wire rope 603 pass through the two through holes 606 respectively. In this embodiment, the through holes 606 are arranged symmetrically with one end of the first steel wire rope 602 and the second steel wire rope 603 installed on the top of the transverse plate 601, so that when the first steel wire rope 602 and the second steel wire rope 603 change the direction of the force through the first fixed pulley 604 and the second fixed pulley 605, the stability is further improved.

[0035] Furthermore, the number of cylinders 5 is set to two, and another horizontal plate 601 is fixedly connected to the output end of the cylinder 5. In this embodiment, the lifting and lowering of the two lifting plates 2 can be driven by the two cylinders 5, further improving the accuracy of the synchronous adjustment of the winding roller.

[0036] Furthermore, the transverse plate 601 is centrally arranged on the side wall of the lifting plate 2. In this embodiment, the transverse plate 601 is centrally arranged in the center of the lifting plate 2, so that the lifting plate 2 is more stable when moving.

[0037] like Figures 1 to 3 As shown, the two lifting plates 2 are both arranged on one side of the cold water trough body 1, and the driving mechanisms are both arranged on the other side of the cold water trough body 1; two slide grooves are provided through the side wall of the cold water trough body 1, and one end of the cross plate 601 is arranged in the slide groove and slides with it. In this embodiment, the driving mechanism is arranged on the back side of the cold water trough body 1, which is not only convenient for maintenance, but also prevents the driving mechanism from hindering the normal operation of the strapping tape when the strapping tape is rolled up.

[0038] Furthermore, two sets of limit grooves are installed on one side of the cold water tank body 1 close to the lifting plate 2 through bolts. Both sides of the lifting plate 2 are located in the limit grooves and slide with them. In this embodiment, the movement of the lifting plate 2 is further limited by two sets of symmetrically arranged limit grooves, thereby further improving the stability of the movement of the lifting plate 2.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
