Description

Technical Field

[0001] This invention relates to the field of film extrusion equipment technology, and more specifically to a roller-type film extrusion equipment. Background Technology

[0002] In the production process of electroplated copper film, after the copper film is acid-plated and washed, in order to ensure that the surface moisture can be dried by the oven, most of the cleaning water adhering to the surface must be squeezed out first. Therefore, the film squeezing device was developed.

[0003] A foil extrusion lifting mechanism and foil extrusion device, disclosed in Chinese Patent Publication No. CN217110238U, includes two parallel lifting mechanisms. Each lifting mechanism comprises a drive mechanism, a slide rail, a slider, and a mounting plate. The drive mechanism has a drive shaft whose movement direction is the same as the lifting direction of the extrusion roller. The slide rail is located beside the movement trajectory of the drive shaft. The slider is movably mounted on the slide rail, and its movement direction is along the movement direction of the drive shaft. The mounting plate is fixedly mounted on the slider, and the movement trajectory of the drive shaft passes through the top of the mounting plate. The mounting plates of the two lifting mechanisms face each other, and both mounting plates are used to mount the extrusion roller. The aforementioned extrusion device uses the lifting mechanism to drive the extrusion roller to press against the roller, achieving the extrusion purpose.

Detailed Implementation

[0031] To make the technical problems, technical solutions, and beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] It should be noted that the terms "set," "connect," "fix," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components, unless otherwise explicitly defined. The terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," and "outer" indicate the orientation or position based on the orientation or position shown in the accompanying drawings, and are only for ease of description and should not be construed as limiting the technical solution.

[0033] Please see Figures 1 to 5This embodiment provides a roller-type film extrusion device, including: a pressure roller 1, a guide roller 2, and two opposing support plates 3. The pressure roller 1 and the guide roller 2 are disposed between the two support plates 3, with the guide roller 2 located below the pressure roller 1. Both ends of the guide roller 2 are rotatably connected to the lower ends of the corresponding support plates 3. Support grooves 31 are provided on the upper ends of the two support plates 3. Support sliders 32 that can slide up and down are disposed within the support grooves 31. Two or more evenly distributed springs 33 are disposed between the support sliders 32 and the top wall of the support grooves 31. The upper ends of the springs 33 abut against the top wall of the support grooves 31, and the lower ends of the springs 33 abut against the top of the support sliders 32. Both ends of the pressure roller 1 are rotatably connected to the corresponding support sliders 32. Under the downward elastic force of the springs 33 and its own weight, the pressure roller 1 presses against the roller surface of the guide roller 2, thereby squeezing the copper film passing between the pressure roller 1 and the guide roller 2 and removing the liquid from the surface of the copper film. Spring 33 can buffer the impact force between the roller and the film during squeezing and stabilize the squeezing force between the two rollers within a certain range, so that the squeezing effect is uniform and stable, and prevents the squeezing force from being too large and damaging the copper film. The above-mentioned roller-type film squeezing device, through the setting of support groove 31, support slider 32 and spring 33, realizes that the pressure roller 1 is pressed against the roller surface of the roller 2, so that the squeezing is uniform and stable, without damaging the film, and the residual moisture on the film surface is very small; and the overall structure is simple and compact, with a small footprint and low cost.

[0034] Please see Figures 2 to 5 In this embodiment, the support slider 32 includes an upper slider 321, a lower slider 322, and a slider spacing adjustment assembly disposed between the upper slider 321 and the lower slider 322. The upper slider 321 is connected to the lower slider 322 through the slider spacing adjustment assembly. The top of the upper slider 321 abuts against the lower end of the spring 33, and the lower slider 322 is rotatably connected to the end corresponding to the pressure roller 1. The slider spacing adjustment assembly can finely adjust the spacing between the upper slider 321 and the lower slider 322, thereby finely adjusting the squeezing force between the two rollers and adjusting the squeezing effect according to the film thickness or material, so that the squeezing effect reaches the optimal level.

[0035] Please see Figures 2 to 5Specifically, the slider spacing adjustment assembly includes a tapered adjusting slider 323, an adjusting screw 324, an adjusting knob 325, and a screw front and rear limit block 326. The screw front and rear limit block 326 is fixed to the support plate 3. The middle part of the adjusting screw 324 is engaged in the U-shaped groove 3261 of the screw front and rear limit block 326, and can slide up and down and rotate freely along the U-shaped groove 3261. The front end of the adjusting screw 324 is connected to the adjusting knob 325, and the rear end of the adjusting screw 324 is screwed to the tapered adjusting slider 323. The tapered adjusting slider 323 includes an upper sliding slope 3231 and a lower sliding slope 3232. The bottom of the upper slider 321 is provided with an upper connecting groove 3211. The left and right ends of the upper sliding slope 3231 are engaged in the upper connecting groove 3211 and can move back and forth along the upper connecting groove 3211. The top of the lower slider 322 is provided with a lower connecting groove 3221. The left and right ends of the lower sliding slope 3232 are engaged in the lower connecting groove 3221 and can move back and forth along the lower connecting groove 3221. When adjusting the distance between the upper slider 321 and the lower slider 322, the adjusting knob 325 is rotated. The adjusting knob 325 drives the adjusting screw 324 to rotate synchronously. Under the action of the thread, the conical adjusting slider 323 slides back and forth along the upper connecting groove 3211 and the lower connecting groove 3221. As the conical adjusting slider 323 moves back and forth, the upper slider 321 and the lower slider 322 move closer to each other or further away under the action of the upper sliding inclined surface 3231 and the lower sliding inclined surface 3232 of the conical adjusting slider 323. The above-mentioned slider distance adjustment component has a simple and compact structure, which can stably fine-tune the distance between the upper slider 321 and the lower slider 322, thereby achieving fine-tuning of the squeezing force between the two rollers.

[0036] Please see Figure 5 Furthermore, an annular groove 3241 is provided in the middle of the adjusting screw 324. The adjusting screw 324 is engaged in the U-shaped groove 3261 of the screw front and rear limiting block 326 through the annular groove 3241, and can slide up and down and rotate freely along the U-shaped groove 3261. The above-mentioned setting of the screw front and rear limiting block 326 and the adjusting screw 324 facilitates the installation and front and rear limiting of the adjusting screw 324.

[0037] Please see Figure 5 Furthermore, the rear end of the adjusting screw 324 is provided with an external thread 3242, and the front end of the tapered adjusting slider 323 is provided with a threaded hole 3233 that mates with the external thread 3242. The adjusting screw 324 achieves a threaded connection with the tapered adjusting slider 323 through the external thread 3242 and the threaded hole 3233.

[0038] Please see Figures 1 to 4In this embodiment, vertical linear guide rods 34 are provided on the left and right sides inside the support groove 31. Linear bearings 35 are provided at both ends of the upper slider 321 and the lower slider 322. The upper slider 321 and the lower slider 322 are sleeved on the corresponding linear guide rods 34 through the linear bearings 35, thereby achieving stable up and down sliding in the support groove 31.

[0039] Please see Figures 1 to 4 In this embodiment, a pressure roller lifting assembly 36 is provided on the top of the support plate 3. The pressure roller 1 can be lifted up by the pressure roller lifting assembly 36, so that the roller surface of the pressure roller 1 is separated from the roller surface of the passing roller 2. At this time, there is no liquid squeezing effect, and the equipment enters the film-wearing state, so that the workers can properly wear the copper film.

[0040] Please see Figures 2 to 4 Specifically, the pressure roller lifting assembly 36 includes a cam handle 361 and a connecting rod 362. The lower end of the connecting rod 362 is fixed to the top of the support slider 32, and the upper end of the connecting rod 362 passes through the top wall of the support groove 31 and is rotatably connected to the cam of the cam handle 361 via a rotating shaft. The cam has a protruding end away from the rotating shaft and a flat end close to the rotating shaft. When the cam handle 361 is manually straightened, the protruding end of its cam abuts against the top of the support plate 3, the rotating shaft moves away from the top of the support plate 3, and the connecting rod 362 lifts the support slider 32 as the rotating shaft moves upward, thereby simultaneously lifting the pressure roller 1, so that the roller surface of the pressure roller 1 separates from the roller surface of the passing roller 2. At this time, there is no liquid squeezing effect, and the equipment enters the film-piercing state. When the cam handle 361 is manually bent, the flat end of the cam abuts against the top of the support plate 3, the rotating shaft approaches the top of the support plate 3, and the connecting rod 362 lowers the support slider 32 as the rotating shaft moves downward, thereby simultaneously lowering the pressure roller 1. Under the downward elastic force of the spring 33 and its own gravity, the pressure roller 1 presses against the roller surface of the guide roller 2, thereby squeezing the copper film passing between the pressure roller 1 and the guide roller 2 and removing the liquid from the surface of the copper film. The aforementioned pressure roller lifting assembly 36 has a simple structure and can realize the manual switching of the two working states of the equipment.

[0041] Please see Figures 1 to 3 In this embodiment, a bearing seat fixing block 37 is provided at the bottom of the support plate 3, and screw holes are provided on both sides of the bearing seat fixing block 37. When fixing the support plate 3, the screw holes on the bearing seat fixing block 37 are aligned with the screw holes on the worktable, and then the bearing seat fixing block is fixed to the worktable with screws. Since the bearing seat fixing block 37 and the worktable are fixed by fixing screws, when adjusting the position of the support plate 3, the screws can be loosened and removed directly to achieve the effect of disassembling the bearing seat fixing block 37 from the worktable.

[0042] Please see Figures 1 to 3In this embodiment, both ends of the roller 2 are connected to the lower ends of the corresponding support plates 3 via deep groove ball bearings 21. The deep groove ball bearings 21 are installed in the bearing mounting grooves 38 at the lower end of the support plates 3, and bearing insulating covers 22 and bearing pressure covers 23 are sequentially arranged on the outer side of the deep groove ball bearings 21. The bearing pressure covers 23 are fixed to the opening of the bearing mounting grooves 38. The deep groove ball bearings 21 have the advantages of low frictional resistance and high rotational speed, which facilitates the rotation of the roller 2 on the support plates 3.

[0043] Please see Figures 1 to 3 In this embodiment, one end of the roller 2 passes through the corresponding support plate 3 and is equipped with a transmission wheel 24. The roller 2 is connected to the servo motor through the transmission wheel 24. Under the control and drive of the servo motor, the roller 2 makes the roller surface linear speed and the film feeding speed consistent and synchronized, so that the surface of the roller 2 and the copper film roll and adhere together, avoiding scratches and wear on the copper film during extrusion, and ensuring uniform and reliable extrusion.

[0044] In this embodiment, the pressure roller 1 is a rubber-coated roller, and the guide roller 2 is a steel roller. The combination of two extrusion rollers with different hardness can greatly improve the extrusion effect.

[0045] In another embodiment, the guide roller 2 can also be located above the pressure roller 1. Both ends of the guide roller 2 are rotatably connected to the upper ends of the corresponding support plates 3. The support groove 31 is located at the lower end of the support plate 3. Two or more evenly distributed springs 33 are arranged between the support slider 32 and the bottom wall of the support groove 31. The upper ends of the springs 33 abut against the bottom of the support slider 32, and the lower ends of the springs 33 abut against the bottom wall of the support groove 31. Under the upward elastic force of the springs 33, the pressure roller 1 presses against the roller surface of the guide roller 2, thereby squeezing the copper film passing between the pressure roller 1 and the guide roller 2 and removing the liquid from the surface of the copper film.

[0046] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
