Description

Technical Field

[0001] This utility model belongs to the technical field of sampling devices, specifically relating to a embossing device for a casting machine that facilitates the replacement of embossing rollers. Background Technology

[0002] Casting machines are specialized automated equipment used in the production of films and sheets, widely used in industries such as plastics, electronics, and new energy. The equipment heats and melts plastic granules, or applies a prepared slurry through a precision die, uniformly coating and casting it onto cooling rollers or a base belt. After rapid cooling, drying, and curing, a smooth film is formed. Following processes such as edge trimming, inspection, traction, and winding, the finished product is produced. The films produced are characterized by uniform thickness, good light transmittance, high flatness, and stable production efficiency. They can be used to manufacture packaging films, electronic ceramic films, and lithium battery-related functional films, making them a core and essential piece of equipment in the film manufacturing field. The embossing station of the casting equipment is equipped with two sets of core rollers: a forming roller and a rubber roller. The forming roller has a pre-set textured pattern on its outer surface. The rubber roller is positioned adjacent to the forming roller. During operation, the roller surface pressure tightly adheres the conveyed film to the surface of the forming roller, and the embossing process is completed on the film surface using the roller's texture. Simultaneously, the rubber roller has an internal circulating water cooling channel, with continuous circulation of cold water to cool the roller itself and indirectly cool and shape the film in contact. To facilitate film feeding, the rubber roller is typically installed at a relatively high position, but this also presents maintenance challenges: when disassembling and replacing the roller is required for equipment maintenance or process changes, the high installation height significantly increases the difficulty for operators to access and remove it, resulting in poor operational convenience. Utility Model Content

[0003] The purpose of this invention is to provide a embossing device for a casting machine that facilitates the replacement of embossing rollers, thereby solving the problems existing in the background art.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: An embossing device for a casting machine that facilitates the replacement of embossing rollers includes two mounting plates. A forming roller is mounted between the two mounting plates. A support frame is provided on the front side of each of the two mounting plates. A rotating frame is rotatably mounted between the two support frames. A rubber roller matching the forming roller is mounted between one side of each of the two rotating frames. Each of the two rotating frames is equipped with a driving mechanism. The driving mechanism can drive the rotating frame to rotate. The rotation of the rotating frame can cause the rubber roller to have a first position and a second position relative to the forming roller. When the rubber roller is in the first position, it is in close contact with the outer surface of the forming roller. When the rubber roller is in the second position, it is away from the forming roller.

[0005] A stabilizing bar is provided between the two mounting plates. The driving mechanism includes a first cylinder. The rear end of the first cylinder is rotatably connected to the stabilizing bar. The output end of the first cylinder is rotatably connected to the rotating frame. The connection between the output end of the first cylinder and the rotating frame and the rubber roller are located on both sides of the rotating frame. The middle part of the rotating frame is rotatably connected to the support frame.

[0006] Both ends of the rotating frame are provided with a first semi-circular fastener, and each of the two first semi-circular fasteners is fitted with a second semi-circular component by screws. A bearing is fitted between the first semi-circular fastener and the second semi-circular component, and the two bearings are respectively connected to both sides of the rubber roller.

[0007] The rubber roller has a water storage chamber inside, and cold water can be continuously injected into the water storage chamber in a flowing manner when the rubber roller rotates.

[0008] A cold pressing mechanism is assembled between the two rotating frames. The cold pressing mechanism includes two cold pressing components, each of which includes a metal roller. The two ends of the metal roller are rotatably connected to the two rotating frames, respectively.

[0009] Both ends of the two metal rollers are rotatably fitted with sliders, which are slidably mounted on the surface of the rotating frame. The rotating frame is equipped with a second cylinder, the output end of which is connected to the slider.

[0010] The rotating frame is provided with a limiting component, the limiting component is provided with a limiting groove, and the slider is slidably assembled in the limiting groove.

[0011] This utility model has the following technical advantages compared with the prior art: This device uses a cylinder to drive the rotating frame to swing, which allows the rubber roller to be quickly separated from the forming roller. The overall height of the rubber roller is reduced accordingly, and there is no longer any structural obstruction below. Operators can directly place the transfer tooling, which greatly simplifies the disassembly and transportation process of the rubber roller. It changes the problem of inconvenient disassembly and assembly of traditional high-position rollers, and makes daily maintenance operations smoother.

[0012] The rubber roller adopts a combination installation structure of semi-circular fasteners and bearings. The disassembly of the rubber roller can be completed by simply removing the fixing screws and taking off one side of the semi-circular fastener. The disassembly and assembly steps are simple and do not require complicated special tools, which reduces the skill requirements of the operators and shortens the time spent on rubber roller replacement.

[0013] The roller has a circulating water storage chamber inside, and cold water is continuously circulated to achieve water cooling of the roller body. While completing the film embossing operation, the contact film can be cooled and shaped at the same time, realizing the two processes of embossing and cooling in one piece. There is no need to add an additional independent cooling equipment, making the overall equipment structure more compact.

[0014] The device is equipped with an additional metal roller as an auxiliary heat dissipation structure. The metal roller can adhere to the surface of the rubber roller to absorb and conduct heat. Together with the rubber roller's own water cooling system, it forms a dual cooling method, which effectively improves the overall heat dissipation capacity of the rubber roller. This can prevent the roller from overheating during long-term operation and ensure the continuous and stable operation of the equipment.

[0015] The metal roller is equipped with a slider, a limiting groove, and an independent cylinder structure, which can flexibly control the contact or separation state between the metal roller and the rubber roller. During the assembly and disassembly of the rubber roller, the metal roller can actively avoid it, further expanding the operating space. At the same time, the limiting structure ensures the stability of the metal roller's sliding trajectory, preventing problems such as deviation or jamming. Attached Figure Description

[0022] like Figure 1-6 As shown, the present invention provides a embossing device for a casting machine that facilitates the replacement of embossing rollers. It includes two mounting plates 1, with a forming roller 11 mounted between the two mounting plates 1. Each mounting plate 1 has a support frame 12 on its front side, and a rotating frame 13 is rotatably mounted between the two support frames 12. A rubber roller 14 matching the forming roller 11 is mounted between one side of each of the two rotating frames 13. Each rotating frame 13 is equipped with a driving mechanism, which can drive the rotating frame 13 to rotate. The rotation of the rotating frame 13 can cause the rubber roller 14 to have a first position and a second position relative to the forming roller 11. When the rubber roller 14 is in the first position, it is in close contact with the outer surface of the forming roller 11. When the rubber roller 14 is in the second position, it is away from the forming roller 11.

[0023] Two mounting plates 1 provide support for the whole. The forming roller 11 is driven and assembled between the two mounting plates 1. The forming roller 11 can be driven to rotate by a motor. The outer surface of the forming roller 11 has a pattern, which can leave a pattern on the film surface when in contact with the film pressure. The film passes between the forming roller 11 and the rubber roller 14. The rubber roller 14 is mounted between two rotating frames 13, and the two rotating frames 13 are rotatably connected to two mounting plates 1 respectively. Both rotating frames 13 are equipped with a drive mechanism, which can drive the rotating frames 13 to rotate. Therefore, when the drive mechanism extends and drives the two rotating frames 13 to rotate, the rubber roller 14 rotates upward and moves towards the outer surface of the forming roller 11 until the rubber roller 14 is in close contact with the outer surface of the forming roller 11, pressing the film tightly onto the outer surface of the forming roller 11. This completes the forming process of the film. When the rubber roller 14 needs to be replaced or maintained, the drive mechanism can retract, causing the rotating frame 13 to rotate in the opposite direction. The rotating frame 13 drives the rubber roller 14 to rotate downwards, away from the outer surface of the forming roller 11, until the drive mechanism retracts to its maximum. At this time, the horizontal height of the rubber roller 14 can be reduced. Since the rubber roller 14 is tilted to one side under the support of the rotating frame 13, there is no obstruction under the rubber roller 14. The operator can place the support part of the transfer cart of the rubber roller 14 directly under the rubber roller 14. After the rubber roller 14 is disassembled, it can be placed directly on the support part of the transfer cart. This design can reduce the transfer height of the rubber roller 14 when it needs to be replaced or maintained, and it is convenient to place a support under the rubber roller 14, reducing the labor burden of the operator.

[0024] A stabilizing bar 15 is provided between the two mounting plates 1. The driving mechanism includes a first cylinder 16. The rear end of the first cylinder 16 is rotatably connected to the stabilizing bar 15. The output end of the first cylinder 16 is rotatably connected to the rotating frame 13. The connection between the output end of the first cylinder 16 and the rotating frame 13 and the rubber roller 14 are located on both sides of the rotating frame 13. The middle part of the rotating frame 13 is rotatably connected to the support frame 12.

[0025] The design of the stabilizer bar 15 can improve the stability between the two mounting plates 1. The rear end of the first cylinder 16 is rotatably connected to the stabilizer bar 15, and the output end of the first cylinder 16 is rotatably connected to the rotating frame 13. Therefore, when the first cylinder 16 extends, it can drive the rotating frame 13 and the rubber roller 14 to rotate towards the forming roller 11. When the first cylinder 16 retracts, it can drive the rotating frame 13 to rotate away from the forming roller 11.

[0026] Both rotating frames 13 have a first semi-circular fastener 2 at each end. Each first semi-circular fastener 2 is fitted with a second semi-circular component 21 via screws. A bearing 22 is fitted between the first semi-circular fastener 2 and the second semi-circular component 21, and the two bearings 22 are respectively connected to both sides of the rubber roller 14. The first semi-circular fastener 2 and the second semi-circular component 21 are connected by screws, and the bearing 22 can rotate between the first semi-circular fastener 2 and the second semi-circular component 21. Therefore, when the worker removes the second semi-circular component 21, the rubber roller 14 can be freely removed.

[0027] The rubber roller 14 has a water storage chamber inside, into which cold water is continuously injected in a flowing manner when the rubber roller 14 rotates. When the rubber roller 14 squeezes the forming roller 11, the injection of cold water into the water storage chamber inside the rubber roller 14 can exchange heat inside the rubber roller 14 and cool the rubber roller 14. After heat exchange, the water can flow out of the rubber roller 14, continuously exchanging heat with the rubber roller 14, thereby cooling the film.

[0028] A cold pressing mechanism is assembled between the two rotating frames 13. The cold pressing mechanism includes two cold pressing components, each of which includes a metal roller 23. The two ends of the metal roller 23 are rotatably connected to the two rotating frames 13 respectively.

[0029] The metal roller 23 is in contact with the outer surface of the rubber roller 14. As the rubber roller 14 rotates continuously, the metal roller 23 also rotates continuously. The metal roller 23 can absorb the heat from the outer surface of the rubber roller 14 and conduct the heat to the outside, further improving the cooling effect of the rubber roller 14.

[0030] Both ends of the two metal rollers 23 are rotatably equipped with sliders 24, which are slidably mounted on the surface of the rotating frame 13. The rotating frame 13 is equipped with a second cylinder 25, the output end of which is connected to the sliders 24. The extension and retraction of the second cylinder 25 can move the metal rollers 23 closer to or further away from the rubber roller 14. When disassembling and maintaining the rubber roller 14, the metal rollers 23 can be moved away from the rubber roller 14, making it easier for operators to operate the rubber roller 14. It is worth mentioning that the two metal rollers 23 can alternately contact the forming roller 11, improving the cooling effect on the rubber roller 14.

[0031] The rotating frame 13 is provided with a limiting member 26, and the limiting member 26 is provided with a limiting groove 27. The slider 24 is slidably assembled in the limiting groove 27. The slider 24 can slide in the limiting groove 27 in the limiting member 26, which improves the sliding stability of the slider 27, thereby improving the sliding stability of the metal roller 23.

[0032] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
