Description

Technical Field

[0001] The utility model relates to the technical field of rollers, in particular to a heating roller mechanism for a laminating machine. Background Art

[0002] When a roller laminating machine is used, it is necessary to convey the material through multiple rollers, and use the heated rollers among them in combination with adhesives to achieve lamination between the materials. Existing patent number CN211416565U proposes a new type of heating roller mechanism for a laminating machine, including a roller body, a roller side shaft, and a roller bearing. A transverse through-type cavity is provided in the middle of the roller body. The roller side shaft is located at both ends of the roller body and is coaxially connected to the roller body. The roller side shaft is connected to the inner ring of the roller bearing. A heating rod is provided in the cavity of the roller body, with both ends extending from the roller side shaft. The coupling end of the heating rod is placed in the coupling end of the roller side shaft and is arranged on the same axis. The utility model facilitates maintenance of the components in the cavity of the roller body and can effectively reduce production costs. The spiral heating structure can evenly heat the roller body, so that the product of the laminating roller is evenly heated, thereby ensuring the laminating quality and having high stability and durability.

[0003] However, during the use of the above-mentioned heating roller, it is mostly only bonded to the material of the laminating machine through the lower part, and the adhesive is bonded through heat conduction. After the upper part rotates and separates from the material, it will continue to absorb the heat of the heating tube and dissipate it to the outside, resulting in a large amount of heat loss. The heating tube needs to continuously maintain a higher temperature to make up for the lost heat, which increases the failure rate of the heating tube and increases energy waste.

[0004] For this reason, a heating roller mechanism for a laminating machine is proposed. Utility Model Content

[0005] The purpose of the present invention is to solve the above problems and provide a heating roller mechanism for a laminating machine.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] A heating roller mechanism for a laminating machine includes a side shaft, the outer side of the side shaft is rotatably connected to a roller via a bearing, one side of the side shaft is open and a heating rod is installed, at least four oil cylinders are arranged in a ring distribution on the inner side of the roller, the outer wall of the side shaft inside the roller is provided with a heat insulation cover, the inner side wall of the heat insulation cover is connected to an oil guide ring, the inner side of the oil cylinder is connected to and communicated with a connecting pipe, the free end of the connecting pipe passes through the heat insulation cover and is connected and communicated with the oil guide ring, the interior of the oil guide ring is filled with heat transfer oil, and the heat transfer oil is injected into the oil cylinder located at the lower part through the connecting pipe.

[0008] Furthermore, one side of the oil guide ring is connected to and communicated with an oil pipe, and an electric control valve is installed at the free end of the oil pipe. An oil storage cylinder is provided on the side of the side shaft at a position corresponding to the oil pipe, and the oil storage cylinder is filled with heat transfer oil. A piston is sleeved on the inner wall of the oil storage cylinder, and a plug rod is connected to one side of the piston. The free end of the plug rod passes through the piston, and the side of the oil storage cylinder facing away from the plug rod is connected to and communicated with an oil filling pipe, and the oil filling pipe corresponds to the position of the electric control valve.

[0009] Furthermore, the free end port of the oil delivery pipe is inclined downward, and the free end port of the oil filling pipe is inclined upward.

[0010] Furthermore, a through hole is opened on the left side of the drum, and a roller cover is installed in the through hole, and the roller cover is rotatably connected to the side shaft through a bearing.

[0011] Furthermore, a mounting bracket is installed at one end of the side shaft, and a telescopic motor 1 is installed at an inclination on the bottom side of the mounting bracket. The transmission shaft of the telescopic motor 1 is connected to the oil storage cylinder. The inclination angle of the telescopic motor 1 is consistent with the inclination angle of the free end of the oil filling pipe. Telescopic motor 2 is installed on one side of the oil storage cylinder, and the transmission shaft of the telescopic motor 2 is connected to the plug rod.

[0012] Furthermore, the outer wall of the side shaft located inside the drum is rotatably connected to the heat insulation cover through a bearing, and at least four heat conduction grooves are opened on the inner side of the drum, and a plurality of oil cylinders are respectively filled in the plurality of heat conduction grooves.

[0013] Furthermore, the inner wall of the oil cylinder is connected to a plurality of supporting heat transfer columns for direct heat conduction, and the free ends of the supporting heat transfer columns are in contact with the side shaft.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. The utility model arranges a number of interconnected oil cylinders so that the heat-conducting oil that performs the heat-conducting function is concentrated in the lower part to ensure that the temperature of the bonding position of the roller is sufficient and stable, and reduces the heat conduction away from the bonding position, thereby reducing the heat dissipation and waste problems. There is no need for the heating rod to maintain a higher heat for a long time to make up for the lost heat, which is conducive to achieving energy-saving effects. In addition, the oil cylinders are used to fill the heat-conducting grooves, reducing the thickness of the contact surface for heat conduction, making it easier for heat to be conducted to the bonding position to improve the bonding effect. The filling of the oil cylinders makes up for the strength defects of the heat-conducting grooves, thereby ensuring the overall strength of the roller.

[0016] 2. The utility model is provided with an oil storage cylinder. After the roller stops, the content of the heat-conducting oil in the oil guide ring is controlled by connecting the oil filling pipe and the oil delivery pipe, thereby adjusting the liquid level of the heat-conducting oil, so that the roller can adjust the heat conduction range according to the contact surface with the material on the laminating machine, thereby better adapting to different usage requirements.

[0025] like Figure 1-3As shown, a heating roller mechanism for a laminating machine includes a side shaft 1, the outer side of the side shaft 1 is rotatably connected to a roller 2 through a bearing, one side of the side shaft 1 is open and a heating rod 3 is installed, and a temperature sensor for detecting the temperature is also provided on the side shaft 1. The temperature sensor is a well-known technology and will not be described in detail here. Eight oil cylinders 4 are arranged in a ring distribution on the inner side of the roller 2, and a heat preservation cover 5 is provided on the outer wall of the side shaft 1 inside the roller 2. The inner wall of the heat preservation cover 5 is connected to an oil guide ring 6, and the inner side of the oil cylinder 4 is connected and connected with a connecting pipe 8. The free end of the connecting pipe 8 passes through the heat preservation cover 5 and is connected and communicated with the oil guide ring 6. The interior of the oil guide ring 6 is filled with heat transfer oil 7. The heat transfer oil 7 is a well-known technology and will not be described in detail here. The heat transfer oil 7 is injected into the oil cylinder 4 at the lower part through the connecting pipe 8.

[0026] As shown in Figure 2, one side of the oil guide ring 6 is connected to and communicated with an oil pipe 9, and an electric control valve 10 is installed at the free end of the oil pipe 9. An oil storage cylinder 11 is provided on one side of the side shaft 1 at a position corresponding to the oil pipe 9. The oil storage cylinder 11 is filled with heat transfer oil 7. A piston 12 is sleeved on the inner wall of the oil storage cylinder 11. A plug rod 13 is connected to one side of the piston 12. The free end of the plug rod 13 passes through the piston 12. The side of the oil storage cylinder 11 facing away from the plug rod 13 is connected to and communicated with an oil filling pipe 14. The oil filling pipe 14 corresponds to the position of the electric control valve 10.

[0027] The free end port of the oil delivery pipe 9 is tilted downward, and the free end port of the oil filling pipe 14 is tilted upward.

[0028] A through hole is opened on the left side of the drum 2, and a roller cover 18 is installed in the through hole. The roller cover 18 is rotatably connected to the side shaft 1 through a bearing.

[0029] A mounting bracket 15 is installed at one end of the side shaft 1, and a telescopic motor 16 is installed at an inclined position on the bottom side of the mounting bracket 15. The transmission shaft of the telescopic motor 16 is connected to the oil storage cylinder 11. The inclination angle of the telescopic motor 16 is consistent with the inclination angle of the free end of the oil filling pipe 14. A telescopic motor 2 17 is installed on one side of the oil storage cylinder 11, and the transmission shaft of the telescopic motor 2 17 is connected to the plug rod 13.

[0030] like Figure 3 As shown, the outer wall of the side shaft 1 located inside the drum 2 is rotatably connected to the heat insulation cover 5 through a bearing. Eight heat conduction grooves 19 are opened on the inner side of the drum 2, and a number of oil cylinders 4 are respectively filled in the heat conduction grooves 19.

[0031] The inner wall of the oil cylinder 4 is connected to a plurality of heat transfer support columns 20 for direct heat conduction, and the free ends of the heat transfer support columns 20 are in contact with the side shaft 1 .

[0032] In summary: before use: first start the telescopic motor 16 to retract the drive shaft, pull the oil storage cylinder 11 to move obliquely upward, and insert the oil filling pipe 14 into the electric control valve 10. After controlling the electric control valve 10 to open, drive the telescopic motor 2 17 to push the piston 12 to compress the heat-conducting oil 7 in the oil storage cylinder 11, and inject the heat-conducting oil 7 into the oil guide ring 6 through the oil filling pipe 14, the electric control valve 10 and the oil delivery pipe 9, thereby increasing the amount of heat-conducting oil 7 in the oil guide ring 6 and the liquid level of the heat-conducting oil 7. Because the oil guide ring 6 is connected to the oil cylinder 4 through the connecting pipe 8, the number of oil cylinders 4 filled with heat-conducting oil 7 located below increases. Conversely, when the telescopic motor 2 17 pulls the piston 12 to reset, the heat-conducting oil 7 in the oil guide ring 6 flows back into the oil storage cylinder 11, thereby lowering the liquid level of the heat-conducting oil 7 in the oil guide ring 6, thereby reducing the oil cylinder 4 filled with heat-conducting oil 7.

[0033] During use: after closing the electric control valve 10, drive the telescopic motor 16 to push the oil filling pipe 14 away from the electric control valve 10, and the heating rod 3 starts to generate heat. The heat is accelerated to the oil guide ring 6 through the supporting heat transfer column 20, and the heat is absorbed by the heat-conducting oil 7. The material of the laminating machine passes through the roller 2 and drives the roller 2 to rotate. While the roller 2 rotates, it drives the insulation cover 5 to rotate through the connection with the oil cylinder 4 through the heat-conducting groove 19. During the rotation process, since several oil cylinders 4 are interconnected, the heat-conducting oil 7 maintains the liquid level unchanged and is always collected in the oil cylinder 4 located below, so that the heat of the heating rod 3 is conducted through the heat-conducting oil 7 and concentrated at the bonding position of the adhesive, and the separation from the upper part of the contact surface with the material reduces the conduction of heat, reduces the heat dissipation and waste problems.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible 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.
