Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a tape roll cooling device. Background Art

[0002] Transparent tape consists of two parts: plastic film and adhesive. The high molecular weight polypropylene sheet can become the film part of the transparent tape after film blowing and stretching. After the unrolled plastic film is stretched and unfolded, a layer of hot-melt adhesive is sprayed on its surface, and the transparent tape can be formed. Since the adhesive itself has a certain temperature, the tape after spraying needs to pass through a cold zone to lower the temperature to avoid excessive temperature accumulation after winding, which will cause the viscosity of the tape to decrease.

[0003] The common tape roll cooling devices on the market are mostly similar in structure. Generally, cooling rollers are used for cooling. The interior of the stainless steel mirror roller is connected to a cold water circulation coil. A movable joint is installed on one side of the roller to import and export cold water in the chiller. There are some functional deficiencies in actual use and there is room for improvement. For example, the height of the roller is fixed. When the tape sprayed with adhesive passes on the roller, its tension is fixed and cannot be adjusted. When the tension is too low, the cooling effect will also be significantly reduced. Failure to adjust it will affect the quality of the entire batch of tapes. It does not have the function of facilitating the adjustment of the roller height.

[0004] Now, a novel tape roll cooling device is proposed to solve the above problems. Utility Model Content

When in use, the water pipe of the chiller is connected to the water inlet pipe and the water outlet pipe. The cold water in the chiller is pumped into the cold water circulation coil along the water inlet pipe. The cold water circulation coil is attached to the inner wall of the stainless steel mirror cooling roller, so that the surface of the stainless steel mirror cooling roller is in a low temperature state. The circulating cold water then flows out along the outlet pipe back to the chiller, and the cycle is repeated.

[0033] Working principle: When the utility model is used, first, the water pipe of the chiller is connected to the water inlet pipe 24 and the water outlet pipe 25, and the cold water in the chiller is pumped into the cold water circulation coil 12 along the water inlet pipe 24. The cold water circulation coil 12 is attached to the inner wall of the stainless steel mirror cooling roller 11, so that the surface of the stainless steel mirror cooling roller 11 is in a low temperature state. The circulating cold water then flows out along the water outlet pipe 25 back to the chiller, and the cycle is repeated. The adhesive tape sprayed with adhesive passes through the top of the stainless steel mirror cooling roller 11, and is affected by the low temperature of the stainless steel mirror cooling roller 11 to reduce its own temperature. The height of the stainless steel mirror cooling roller 11 can be adjusted to change the tension of the tape, so that it is in a taut state and maintains full contact with the stainless steel mirror cooling roller 11. First, loosen and withdraw the positioning bolt 6, and the electric cylinder 9 extends upward or retracts downward, so that the cooling roller mounting frame 4 can be pushed up and down along the sliding groove 8. The side groove 5 fits the inner side of the sliding groove 8, and the up and down sliding is smoother and more stable. Multiple positioning screw eyes 10 allow it to have multiple height options. After adjusting to the appropriate height, re-insert the positioning bolt 6, and then put the anti-stripping nut 7 on the end of the positioning bolt 6 to complete the height fixation. The surface temperature of the stainless steel mirror cooling roller 11 determines the actual effect of cooling the tape. When the surface temperature of the stainless steel mirror cooling roller 11 is too high due to the failure of the chiller, the infrared temperature sensor 16 on the sensor mounting seat 15 keeps monitoring the bottom temperature of the stainless steel mirror cooling roller 11, and the LCD 14 displays the temperature value in real time. When the surface temperature of the stainless steel mirror cooling roller 11 is too high, the operator can find it in time and make adjustments. The cold water in the chiller is pumped into the cold water circulation coil 12 along the water inlet pipe 24, and the circulating cold water then flows out along the water outlet pipe 25 back into the chiller. When the cold water circulation coil 12 is clogged due to scaling, a flow difference will appear between the water inlet pipe 24 and the water outlet pipe 25. The first external clamp-on flow sensor 19 and the second external clamp-on flow sensor 20 can accurately monitor the flow data and feed back the data on the display screen 23 on the back of the PLC logic controller 18. When the value is abnormal, the speaker 21 can sound a reminder, and the control keyboard 22 is convenient for manual query.
