Abstract
Description
Technical Field
[0001] This utility model relates to the field of cast film production technology, and in particular to a temperature control device for the rapid cooling roller in cast film production equipment. Background Technology
[0002] Cast film is a type of non-stretched, non-oriented flat extrusion film produced by rapidly cooling melt casting. It has two main production methods: single-layer casting and multi-layer co-extrusion casting. Compared to blown film, cast film offers faster production speeds, higher output, and superior transparency, gloss, and thickness uniformity.
[0003] Various problems can occur during the production of cast film, among which poor transparency is one of the more common defects. This mainly requires adjusting the temperature of the quench roll while increasing the extrusion temperature to ensure uniform cooling. Existing quench rolls mainly monitor the surface of the quench roll through temperature sensors. When the temperature is too high or too low, the internal cooling water temperature needs to be adjusted, which takes a long time. This results in a large area of defective areas in the cast film. Therefore, the quench roll needs to be adjusted quickly to ensure the quality of cast film production. Utility Model Content
[0004] This invention addresses the deficiencies in the prior art by providing a temperature control device for the rapid cooling roller in a cast film production equipment.
[0005] This utility model is achieved through the following technical solution:
[0006] A temperature control device for a quenching roller in a cast film production equipment includes a gantry frame, a mounting plate, an adjusting mechanism, and a quenching roller assembly. The mounting plate is installed on one side of the gantry frame, the adjusting mechanism is fixedly installed on the outside of the mounting plate, and the quenching roller assembly is engaged with the inside of the adjusting mechanism. The adjusting mechanism includes a sliding seat, a cylinder, a sliding block, a mounting roller, a connecting seat, and a temperature sensor. The sliding seat is fixedly connected to the outside of the mounting plate, the cylinder is installed on the top of the sliding seat, the sliding block is fixedly installed at the telescopic end of the cylinder, the mounting roller is fixedly installed inside the sliding block, the connecting seat is sleeved on the outside of one end of the mounting roller, and the temperature sensor is installed inside the connecting seat.
[0007] In a preferred embodiment of the present invention, the rapid cooling roller assembly includes a connecting roller, a water connector, and a rapid cooling pipe. The water connector is disposed at both ends of the connecting roller, and the rapid cooling pipe is movably connected to the connecting roller via bearings.
[0008] The rapid cooling roller assembly mainly achieves the cooling effect by connecting a water channel inside the connecting roller and using cooling water to cool the connecting roller, and by enabling heat exchange between the connecting roller and the extreme cooling tube.
[0009] In a preferred embodiment of this utility model, the connecting roller is sleeved on the outside of the mounting roller, and a water channel is transversely opened inside the connecting roller. The water channel connector is set at both ends of the water channel inside the connecting roller. The quench tube is made of copper, and its inner wall is in contact with the outer surface of the connecting roller.
[0010] The water passage inside the connecting roller is equipped with a plug to facilitate water passage connection, and the copper quench tube has a better heat dissipation effect.
[0011] In a preferred embodiment of this utility model, the temperature sensor's measuring end is located outside one side of the quench tube.
[0012] In a preferred embodiment of the present invention, the sliding block is fitted inside one side of the sliding seat, and its end extends through and to the top outer side of the sliding seat. A guide groove that cooperates with the sliding block is provided on the top of the sliding seat.
[0013] By controlling the sliding block within the sliding seat using a cylinder, the position of the quench tube can be changed, thereby adjusting the cooling time of the cast film more quickly and achieving a more ideal temperature control effect.
[0014] The beneficial effects of this utility model are:
[0015] The temperature control device for the quench roll in this cast film production equipment not only achieves the effect of rapid cooling through the internal water circuit of the ordinary quench roll, but also controls the distance between the quench roll assembly and the extrusion equipment in real time based on the temperature sensor. This allows for more precise control of the temperature of the cast film when it is conveyed to the surface of the quench roll. By adjusting the distance between the quench roll assembly and the extrusion equipment, an ideal cooling effect can be achieved, ensuring the quality of the cast film. Attached Figure Description

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings.

[0022] like Figure 1-4 The temperature control device for the quenching roller of a cast film production equipment shown includes a gantry frame 1, a mounting plate 2, an adjusting mechanism 3, and a quenching roller assembly 4. The mounting plate 2 is installed on one side of the gantry frame 1, the adjusting mechanism 3 is fixedly installed on the outside of the mounting plate 2, and the quenching roller assembly 4 is clamped on the inside of the adjusting mechanism 3. The adjusting mechanism 3 includes a sliding seat 31, a cylinder 32, a sliding block 33, an installation roller 34, a connecting seat 35, and a temperature sensor 36. The sliding seat 31 is fixedly connected to the outside of the mounting plate 2, the cylinder 32 is installed on the top of the sliding seat 31, the sliding block 33 is fixedly installed on the telescopic end of the cylinder 32, the installation roller 34 is fixedly installed on the inside of the sliding block 33, the connecting seat 35 is sleeved on the outside of one end of the installation roller 34, and the temperature sensor 36 is installed inside the connecting seat 35.
[0023] Specifically, the quenching roller assembly 4 includes a connecting roller 41, a water channel connector 42, and a quenching pipe 43. The water channel connector 42 is located at both ends of the connecting roller 41. The quenching pipe 43 is movably connected to the connecting roller 41 through bearings. The connecting roller 41 is sleeved on the outside of the mounting roller 34. A water channel is transversely opened inside the connecting roller 41. The water channel connector 42 is located at both ends of the water channel inside the connecting roller 41. The quenching pipe 43 is made of copper, and its inner wall is in contact with the outer surface of the connecting roller 41. The temperature sensor 36 has its temperature measuring end located outside one side of the quenching pipe 43. The sliding block 33 is locked inside one side of the sliding seat 31, and its end extends through and to the top outside of the sliding seat 31. A guide groove that cooperates with the sliding block 33 is opened on the top of the sliding seat 31.
[0024] In this embodiment, a water channel is provided inside the connecting roller 41, and a water channel connector 42 is installed at the end of the water channel. Cooling water is then connected to the water channel connector 42. After the cooling water flows through the connecting roller 41, it rapidly cools the connecting roller 41. The quench pipe 43 is movably connected to the connecting roller 41 through a bearing. The inner wall of the quench pipe 43 is in contact with the surface of the connecting roller 41. While ensuring the heat transfer effect, the quench pipe 43 does not obstruct the transmission of the cast film, thereby avoiding defects such as scratches and deformation on the surface of the cast film, and ensuring that the quench pipe 43 can effectively cool the transmitted cast film.
[0025] Furthermore, when the cast film is not cooled in time or is over-cooled, the temperature sensor 36 installed at the end of the connector 35 will detect that the surface temperature of the quench tube 43 is too high or too low. At this time, it is necessary to drive the cylinder 32 to extend or retract, and adjust the sliding block 33 within the sliding seat 31 by means of the cylinder 32, so as to change the distance between the quench tube 43 and the extruder, thereby increasing or decreasing the time for the cast film to be extruded to the surface of the quench tube 43, and changing the cooling time of the cast film in the air, thereby achieving a rapid adjustment effect, effectively ensuring the quality of the cast film, and reducing the area of cast film with defects.
