Description

Technical Field

[0002] The non-conductive film conveying guide roller is a guide roller used to convey non-conductive films. It has good insulation performance and wear resistance, which can effectively prevent the film from generating static electricity or being subject to other electrical interference during the conveying process, ensuring the stable conveying and processing quality of the film; the non-conductive film conveying guide roller is usually made of insulating materials, such as ceramics, rubber, plastic, etc. These materials have good insulation performance and wear resistance, which can effectively prevent the film from being subject to electrical interference or wear during the conveying process.

[0003] The non-conductive film material is formed by heating and extrusion. After extrusion, the film material needs to be fed into the cooling device through the conveying guide roller to cool and shape the film. Since the newly formed film is soft and easy to plasticize, the conveying of the guide roller is line contact, which can easily cause the film to deform between the extrusion and cooling processes, and may also cause inconsistent thickness;

[0004] In order to solve the above problems, the present application proposes a conveying guide roller structure for non-conductive film production. Utility Model Content

[0028] See also Figure 1-5As shown, the utility model is a conveying guide roller structure for non-conductive film production, comprising a conveying roller 1 and a mounting seat 2 rotatably mounted at both ends of the conveying roller 1, and a frame 3 for mounting the conveying roller 1, the mounting seat 2 is fixedly mounted on the frame 3, a through slot 4 is provided inside the conveying roller 1, the diameters at both ends of the through slot 4 are smaller than the middle diameter, a central column 5 is provided at the center of the through slot 4, diffuser blocks 6 are formed at both ends of the central column 5, an independent heat dissipation channel is formed between the through slot 4 and the central column 5, a first air duct 8 is connected to one side of the conveying roller 1, and a second air duct 9 is connected to the other side, a blowing port 10 is provided at the front end of the first air duct 8 and the second air duct 9, a diverter 11 is provided at the lower end of the first air duct 8, a transfer cylinder 12 is provided between the diverter 11 and one end of the conveying roller 1, a flow regulating plate 14 with an adjustable air outlet gap is hinged inside the first air duct 8 and the second air duct 9, and the flow regulating plate 14 in this embodiment can adjust the blowing distance according to the thickness of the film, so as to adapt to the efficient heat dissipation of films of different widths.

[0029] Among them, a connecting flange 13 is provided at one end of the diverter 11 away from the adapter tube 12. The diverter 11 is externally connected to the fan through the connecting flange 13. The fan airflow is distributed to the first air duct 8 and the adapter tube 12 through the diverter 11. In this embodiment, the diverter 11 guides less than half of the airflow to the first air duct 8, and the other airflow enters the through groove 4 and the second air duct 9, which can better distribute the airflow and ensure the uniformity of heat dissipation.

[0030] Among them, the diffuser block 6 is located at the overlap of different diameters of the through slot 4, and the reinforcing ribs 7 are evenly distributed in a circle between the through slot 4 and the center column 5. In this embodiment, the diffuser block 6 can evenly diffuse the airflow of small diameters in the through slot 4 into the airflow of large diameters, and vice versa, thereby ensuring uniform heat dissipation.

[0031] Among them, the first air duct 8 and the second air duct 9 are both provided with a penetrating adjusting screw 15, and a transfer rod 16 is hinged between one end of the adjusting screw 15 and the flow regulating plate 14 through a rotating shaft, and a fixed turning wheel 17 is provided at the other end of the adjusting screw 15. In this embodiment, the transfer rod 16 is used to ensure power transmission while also adapting to position and angle differences, and has strong flexibility.

[0032] Among them, the first air duct 8 and the second air duct 9 are both provided with threads spirally connected to the adjusting screw 15, the flow regulating plate 14 is inclined, and the end away from the hinged end of the channel can fit tightly with the surface of the other end of the channel. The thread adjustment in this embodiment has high flexibility and reliability, and the other end of the flow regulating plate 14 hinged to the air duct fits with the other side of the air duct, ensuring the flow regulation accuracy.

[0033] Among them, the mounting seat 2 and the frame 3 are both provided with through holes for external airflow at the end of the conveying roller 1. In this embodiment, the through holes are used to ensure smooth airflow between the adapter tube 12 and the conveying roller 1 without affecting the conveying work of the conveying roller 1.

[0034] Among them, the first air duct 8 and the second air duct 9 are inclined downward at one end close to the blowing port 10, and the blowing port 10 is facing the upper surface of the film. In this embodiment, air is blown from the side from top to bottom. After the airflow contacts the film, it will continue to flow along the film, ensuring the airflow coverage area, thereby ensuring the heat dissipation effect.

[0035] It can be understood that, firstly, heat conduction heat dissipation at the lower end and blowing heat dissipation at the upper end are set, which can realize rapid cooling of the film during transportation and adapt to the film transportation work after extrusion. At the same time, the upper and lower heat dissipation only needs to be connected to one fan, and the energy utilization rate is higher. Secondly, the flow regulating plate 14 for adjusting the air flow in the air duct can adjust the blowing distance according to the thickness of the film, so as to adapt to the efficient heat dissipation of films of different widths.

[0036] A specific application of this embodiment is: the connecting flange 13 is externally connected to the fan. If it is necessary to drive the conveying roller 1, the drive can be directly realized through transmission parts such as gears or pulleys at both ends of the conveying roller 1. The driven conveying roller 1 rotates on the mounting seat 2, and the film passes through the upper end of the conveying roller 1. The air blown out by the fan is partially guided to the first air duct 8 under the action of the diverter 11, and then blows to one side of the upper end of the film through the blowing port 10. The diverter 11 also guides the airflow into the through groove 4 through the adapter tube 12. Under the action of the diffuser block 6, the air blown out by the fan is partially guided to the first air duct 8. Then, the air blows to the upper end of the film through the blowing port 10. The diverter 11 also guides the airflow into the through groove 4 through the adapter tube 12. The airflow flows along the inner wall of the through groove 4. The reinforcing ribs 7 are made of good heat-conducting material. The heat on the film will be directly absorbed by the reinforcing ribs 7. Since the reinforcing ribs 7 are thin, the heat can be quickly conducted to the through groove 4. The heat is taken out by the airflow flowing in the through groove 4. The airflow passing through the through groove 4 enters the second air duct 9 and is blown out from the blowing port 10. The airflow blown out from the second air duct 9 carries a certain amount of heat but is lower than the film temperature, and needs to be mixed with the external normal temperature air and then blown to the other side of the upper end of the film, thereby ensuring the cooling and shaping effect of the film.

[0037] When the air outlet speed of the air outlet 10 needs to be adjusted: the adjusting screw 15 is rotated by the turning wheel 17, and the adjusting screw 15 drives the transfer rod 16 to move through the spiral between the adjusting screw 15 and the channel, and the transfer rod 16 pulls the flow regulating plate 14, and the channel gap is changed by changing the angle of the flow regulating plate 14, thereby changing the air outlet speed.
