Description

Technical Field

[0001] This utility model relates to the field of roller press technology, and in particular to a pre-coated film roller press. Background Technology

[0002] In today's packaging, printing, and other industries, the application of pre-coated films is becoming increasingly widespread. As an important composite material, pre-coated films are extensively used for surface protection and decoration of various products. A pre-coated film roller press plays a crucial role in the pre-coated film production process; its performance directly affects the quality and production efficiency of the pre-coated film, and is of great significance to the development of the entire industry.

[0003] Currently, in the pre-coated film production field, common roller pressing equipment mainly adopts the traditional fixed-gap roller pressing structure. This structure typically consists of fixed upper and lower rollers, and the rollers are driven by a motor to achieve the roller pressing operation on the material. In terms of technical principle, it mainly relies on the material passing between rollers with a fixed gap, and the pressure of the rollers to bond the film layer to the substrate. This structure is simple and direct, and can meet basic production needs to a certain extent.

[0004] However, this traditional fixed-gap, non-adjustable roller pressing structure has a significant problem: because the gap between the rollers cannot be flexibly adjusted, it is difficult to precisely control the film thickness during production. When producing pre-coated films with different thickness requirements, it is difficult to make precise adjustments according to actual needs. Moreover, the fixed gap is prone to unevenness, which leads to local thickening or thinning of the film layer during pre-coated film production. This easily affects the uniformity and stability of the film thickness, thereby reducing product quality and making it difficult to meet the growing demand for high-quality products. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pre-coated film roller press, which aims to improve the problem that traditional fixed-gap roller presses are difficult to adjust precisely according to actual needs when producing pre-coated films with different thickness requirements. This can easily affect the uniformity and stability of the film thickness, thereby reducing product quality and making it difficult to meet the growing demand for high-quality products.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pre-coated film roller press, comprising an outer frame, a connecting plate fixedly connected to the inner wall of the outer frame, an inner frame slidably connected to the inner wall of the outer frame, a roller fixedly connected to the inner wall of the inner frame, a moving component disposed above the inner frame, and a cooling component disposed outside the outer frame;

[0007] The movable component includes a second fixed plate, the lower surface of which is fixedly connected to the upper surface of the inner frame. A first fixed plate is fixedly connected to the upper surface of the second fixed plate. A rotating shaft is fixedly connected to the inner wall of the first fixed plate. A second connecting rod is rotatably connected to the outer wall of the rotating shaft. A slider is rotatably connected to the outer wall of the second connecting rod. A bidirectional lead screw is threaded to the inner wall of the slider. A first connecting rod is fixedly connected to one end of the bidirectional lead screw. A handle is fixedly connected to one end of the first connecting rod.

[0008] Furthermore, the cooling assembly includes a cooling water tank, which is disposed outside the outer frame. A delivery pipe is fixedly connected to the inner wall of the cooling water tank. A cooling pipe is fixedly connected to one end of the delivery pipe. A fan is disposed above the cooling pipe. A ventilation pipe is fixedly connected to the upper surface of the connecting plate. A filter cover is threadedly connected to the top of the ventilation pipe.

[0009] Furthermore, the outer wall of the fan is fixedly connected to the inner wall of the connecting plate, and the fan is used to drive air into the interior of the connecting plate.

[0010] Furthermore, the outer wall of the delivery pipe is fixedly connected to the inside of the connecting plate, and the delivery pipe is used to deliver coolant to the inside of the cooling pipe.

[0011] Furthermore, the middle part of the conveying pipe is fixedly connected inside the outer frame, and the outer frame is used to support the conveying pipe.

[0012] Furthermore, the connecting plate is disposed on one side of the roll, and the connecting plate is used to cool the pre-coated film.

[0013] Furthermore, the outer wall of the slider is slidably connected to the inside of the outer frame, and the outer frame is used to guide the slider.

[0014] Furthermore, the outer wall of the connecting rod is rotatably connected to the inner wall of the outer frame, and the handle is located on one side of the outer wall of the outer frame.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the connecting rod one and the bidirectional lead screw can be driven to rotate inside the outer frame by the drive handle. By utilizing the threaded relationship between the bidirectional lead screw and the slider, the sliders on both sides can move relative to each other, thereby driving the connecting rod two, the fixing plate two, the inner frame and the roller to adjust up and down. This realizes the flexible adjustment of the gap between the upper and lower rollers, which can not only accurately control the thickness of the film layer, but also effectively solve the problem that uneven gap may cause local thickening or thinning of the coating. This greatly improves the uniformity and stability of the film layer thickness during the pre-coated film production process and ensures product quality.

[0017] 2. In this invention, when the material moves off one side of the roller, the fan starts, drawing external air into the connecting plate. The air is then evenly sprayed onto the material surface through the through-holes at the bottom of the connecting plate, helping to maintain stable coating quality. During the air intake process, it is first transported through a ventilation pipe and filtered by a filter cover to prevent impurities from affecting the material. The filter cover can be easily removed for cleaning and maintains good filtration performance over a long period. Simultaneously, the conveying pipe transports coolant from the cooling water tank to the cooling pipe, cooling the air inside the connecting plate. This effectively prevents overheating of the material, which could lead to film deformation, poor adhesion, or a decline in material performance, further improving product quality and production efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 3An embodiment of this utility model provides a pre-coated film roller press, including an outer frame 1, a connecting plate 3 fixedly connected to the inner wall of the outer frame 1, an inner frame 18 slidably connected to the inner wall of the outer frame 1, a roller 2 fixedly connected to the inner wall of the inner frame 18, a moving component provided above the inner frame 18, the moving component being used to drive the inner frame 18 to move, the inner frame 18 being able to slide relative to the inner wall of the outer frame 1, and a cooling component provided outside the outer frame 1, the cooling component being used to cool the heat generated during the pre-coated film roller pressing process;

[0025] The movable component includes a second fixed plate 17, the lower surface of which is fixedly connected to the upper surface of the inner frame 18. A first fixed plate 16 is fixedly connected to the upper surface of the second fixed plate 17. A rotating shaft 15 is fixedly connected to the inner wall of the first fixed plate 16. The rotating shaft 15 provides a support point for the rotation of the second connecting rod 14. The second connecting rod 14 is rotatably connected to the outer wall of the rotating shaft 15. A slider 13 is rotatably connected to the outer wall of the second connecting rod 14. A bidirectional lead screw 12 is threadedly connected to the inner wall of the slider 13. The bidirectional lead screw 12 drives the sliders 13 on both sides to move relative to each other. A first connecting rod 11 is fixedly connected to one end of the bidirectional lead screw 12. A handle 10 is fixedly connected to one end of the first connecting rod 11.

[0026] Specifically, the operator holds the handle 10 and rotates it in the desired adjustment direction. The handle 10 is tightly connected to the connecting rod 11. Rotating the handle 10 will drive the connecting rod 11 to rotate synchronously. The connecting rod 11 is fixed to the bidirectional lead screw 12, so the bidirectional lead screw 12 also rotates inside the outer frame 1. The threads on both sides of the bidirectional lead screw 12 rotate in opposite directions and are threadedly engaged with the slider 13. When the bidirectional lead screw 12 rotates, the sliders 13 on both sides will move relative to each other along the guide rail of the outer frame 1. One end of the slider 13 is connected to the connecting rod 14. When moving, it drives the other end of the connecting rod 14 to drive the fixing plate 17 to move up and down. The fixing plate 17 is fixed to the inner frame 18, which in turn drives the inner frame 18 and the rollers 2 installed on the inner frame 18 to adjust up and down, realizing the adjustment of the gap between the rollers 2. Under different production needs, the film thickness can be precisely controlled, effectively avoiding the problem of local thickening or thinning of the coating due to uneven gaps, and ensuring product quality.

[0027] Reference Figure 1 - Figure 3The cooling assembly includes a cooling water tank 4, which is located outside the outer frame 1. The cooling water tank 4 stores coolant. A delivery pipe 5 is fixedly connected to the inner wall of the cooling water tank 4, which delivers the coolant from the cooling water tank 4 to the interior of the cooling pipe 6. One end of the delivery pipe 5 is fixedly connected to the cooling pipe 6. A fan 7 is installed above the cooling pipe 6. A ventilation pipe 9 is fixedly connected to the upper surface of the connecting plate 3. A filter cover 8 is threadedly connected to the top of the ventilation pipe 9, which filters the air entering the ventilation pipe 9 to prevent dust, impurities, etc. from entering. The outer wall of the fan 7 is fixedly connected to the inner wall of the connecting plate 3, and the fan 7 is used to circulate the air. Inside the connecting plate 3, the outer wall of the conveying pipe 5 is fixedly connected to the inside of the connecting plate 3. The conveying pipe 5 is used to convey coolant to the inside of the cooling pipe 6. The middle part of the conveying pipe 5 is fixedly connected to the inside of the outer frame 1. The outer frame 1 is used to support the conveying pipe 5. The connecting plate 3 is set on one side of the roller 2. The connecting plate 3 is used to cool the pre-coated film. The outer wall of the slider 13 is slidably connected to the inside of the outer frame 1. The outer frame 1 is used to guide the slider 13. The outer wall of the connecting rod 11 is rotatably connected to the inner wall of the outer frame 1. The handle 10 is set on one side of the outer wall of the outer frame 1. The handle 10 is easy for the operator to hold. By rotating the handle 10, the connecting rod 11 can be rotated.

[0028] Specifically, when the material is removed from one side of the roller 2, the start button of the fan 7 is pressed. The fan 7 runs at high speed, generating a strong suction force to introduce external air into the connecting plate 3. The air first enters the ventilation pipe 9, which guides the airflow. Meanwhile, the top filter cover 8 plays its role in intercepting dust, impurities, etc., preventing them from entering the connecting plate 3 and affecting the coating quality of the material. After long-term use, the filter cover 8 will accumulate dirt. The filter cover 8 can be manually rotated and removed for cleaning by using its threaded connection with the ventilation pipe 9. After cleaning, it can be reinstalled to maintain a good filtration effect. One end of the conveying pipe 5 is connected to the cooling water tank 4, and the other end is connected to the cooling pipe 6. The coolant in the cooling water tank 4 is pumped into the cooling pipe 6. The coolant circulates in the cooling pipe 6, using its own low temperature to cool the surrounding air. The cooled air is then blown evenly onto the material surface through the through hole at the bottom of the connecting plate 3, carrying away the heat generated during material coating and preventing the material from overheating and causing quality problems such as film deformation and poor adhesion.

[0029] Working principle: When the pre-coated film roller press is used, the drive handle 10 first drives the connecting rod 11 and the double-acting screw 12 to rotate inside the outer frame 1. At this time, the thread relationship between the double-acting screw 12 and the slider 13 is used to make the sliders 13 on both sides move relative to each other as the double-acting screw 12 rotates. Then, the movement of the sliders 13 can drive one end of the connecting rod 14 to move, and the other end of the connecting rod 14 can drive the fixing plate 17 to move up and down. This can raise the fixing plate 17 to drive the inner frame 18 to slide inside the outer frame 1, thereby raising the inner frame 18 to drive the roller 2 to adjust up and down, realizing the adjustment of the gap between the upper and lower rollers 2. By adjusting the gap, the final thickness of the film layer can be controlled, and the problem of uneven gap may lead to local thickening or thinning of the coating is solved.

[0030] In addition, when the material is removed from one side of the roller 2, the fan 7 is started to drive the external air into the interior of the connecting plate 3. Finally, the air is evenly sprayed onto the surface of the material through the through hole at the bottom of the connecting plate 3, thereby maintaining a stable coating quality. During this process, the air is first conveyed through the ventilation pipe 9 while entering the interior of the connecting plate 3. At this time, the air can be filtered by the filter cover 8 to avoid affecting the material. After long-term use, the filter cover 8 can be driven to rotate on the outer wall of the ventilation pipe 9. With the threaded relationship between the filter cover 8 and the ventilation pipe 9, the filter cover 8 can be easily removed for cleaning to maintain the filtration effect. Then, when the air enters the interior of the connecting plate 3, the coolant in the cooling water tank 4 is conveyed to the interior of the cooling pipe 6 through the conveying pipe 5. The air inside the connecting plate 3 can be cooled by the cooling pipe 6 to prevent the material from overheating and causing problems such as film deformation, poor adhesion, or deterioration of material performance.
