Description
Technical Field
[0001] This utility model relates to the field of silicon nitride cast film production technology, and in particular to a silicon nitride cast film winding mechanism. Background Technology
[0002] Silicon nitride cast film is a ceramic thin film material made of silicon nitride as the core component through a casting process. The silicon nitride cast film winding mechanism is the core module in the cast film production line. It is mainly used to roll the cast silicon nitride film into a roll shape smoothly and without damage, so as to facilitate subsequent processing, transportation and storage.
[0003] However, existing technologies have some problems: existing silicon nitride cast film winding mechanisms cannot adjust the tension according to the change in film roll diameter during silicon nitride cast film winding, which results in excessive tension during winding, causing the silicon nitride cast film to break, or insufficient tension, causing it to loosen after winding. At the same time, they cannot eliminate the instantaneous tension caused by device shaking or malfunction, which makes the silicon nitride cast film prone to breakage. Therefore, we propose a silicon nitride cast film winding mechanism. Summary of the Invention
[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a silicon nitride cast film winding mechanism that maintains stability during the winding process of the silicon nitride cast film by adjusting the components and buffering the components, thereby preventing the silicon nitride cast film from breaking during winding and maintaining the stability of the device.
[0005] This invention is implemented as follows: a silicon nitride cast film winding mechanism includes a base, a feed roller rotatably connected to the base, a groove formed on the base, a slider slidably connected within the groove, an adjustment component on the base for driving the slider to slide, a tension roller rotatably connected to the slider, a buffer roller movably connected to the base, a buffer component on the base, a winding roller rotatably connected to the base, and a drive component on the base for driving the winding roller to rotate.
[0006] Optionally, the adjusting assembly includes a lead screw, which is rotatably connected in a slide groove, the slider is threadedly connected to the lead screw, and a worm gear is fixedly connected to one end of the lead screw.
[0007] Optionally, the adjustment assembly further includes a first motor, which is fixedly connected to the base, and a worm gear is fixedly connected to the output end of the first motor, the worm gear meshing with a worm wheel.
[0008] Optionally, the buffer assembly includes a buffer seat and an adjusting seat. A slide rail is provided on the base. The buffer seat and the adjusting seat are slidably connected in the slide rail. The buffer roller is rotatably connected to the buffer seat. A threaded rod is rotatably connected in the slide rail. The adjusting seat is threadedly connected to the threaded rod. An clearance hole is provided on the buffer seat. The threaded rod passes through the clearance hole. A handle is fixedly connected to one end of the threaded rod.
[0009] Optionally, a buffer spring is fixedly connected to the adjusting seat, the buffer spring is fixedly connected to the buffer seat, a damper is provided inside the buffer spring, one end of the damper is fixedly connected to the adjusting seat, and the other end of the damper is fixedly connected to the buffer seat.
[0010] Optionally, the buffer assembly further includes a fixing seat, the base having a fixing groove, the fixing seat being slidably connected in the fixing groove, the inner wall of the fixing groove having a threaded hole, a fixing bolt being threadedly connected in the threaded hole, the fixing bolt being rotatably connected in the fixing seat, and a rubber pad being fixedly connected to the fixing seat.
[0011] Optionally, the drive assembly includes a second motor, which is fixedly connected to the base. A first gear is fixedly connected to the output end of the second motor, and a second gear is fixedly connected to one end of the take-up roller. The first gear meshes with the second gear.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model is designed with an adjustment component. When winding the silicon nitride cast film, the first motor is started to drive the worm gear to rotate. The rotation of the worm gear will drive the worm wheel to rotate, and the rotation of the worm wheel will drive the lead screw to rotate. The rotation of the lead screw will drive the slider to slide in the groove of the base through the thread engagement, thereby changing the height of the tension roller and thus changing the tension of the silicon nitride cast film during winding. This allows the device to adjust the tension on the silicon nitride cast film in real time according to the change in the film roll diameter (such as from the initial mandrel to the full roll), ensuring that the tension of each layer is constant and avoiding excessive tension that could cause the silicon nitride cast film to break, or insufficient tension that could cause it to loosen after winding.
[0014] 2. This utility model is equipped with a buffer component. During the winding process of silicon nitride cast film, collisions or machine malfunctions may cause the silicon nitride cast film to be subjected to excessive instantaneous tension and break. The buffer component can buffer the instantaneous tension. When the tension suddenly increases, the buffer roller will compress the buffer spring and damper and move into the slide. The compression of the buffer spring and damper will buffer the tension, thereby preventing the silicon nitride cast film from being tightened instantly and breaking.
[0015] 3. This utility model can move the fixing bolt by rotating it and making it move through the threaded engagement with the base, thereby moving the fixing seat so that the fixing seat no longer fixes the threaded rod. At this time, by rotating the throttle, the threaded rod is rotated, causing the adjusting seat to move through its threaded engagement, thereby changing the preload of the buffer spring. This allows the device to be adjusted according to the thickness and tension that the silicon nitride cast film can withstand, thus avoiding the buffer component responding too quickly or too slowly.

[0024] 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.
[0025] like Figures 1 to 6 As shown in the figure, the silicon nitride cast film winding mechanism provided in this embodiment of the present invention includes a base 1. The base 1 is made of stainless steel. The main function of the base 1 is to support the entire device and ensure that the device remains stable during operation.
[0026] Furthermore, a feed roller 2 is rotatably connected to the base 1, a slide groove is provided on the base 1, a slider 3 is slidably connected in the slide groove, an adjustment component 4 is provided on the base 1, the adjustment component 4 is used to drive the slider 3 to slide, and a tension roller 5 is rotatably connected to the slider 3.
[0027] Specifically, the adjusting component 4 includes a lead screw 41, which is rotatably connected in a slide groove. The slider 3 is threadedly connected to the lead screw 41, and a worm gear 42 is fixedly connected to one end of the lead screw 41.
[0028] Furthermore, the adjustment assembly 4 also includes a first motor 43, which is fixedly connected to the base 1. A worm gear 44 is fixedly connected to the output end of the first motor 43, and the worm gear 44 meshes with the worm wheel 42.
[0029] Specifically, when winding the silicon nitride cast film, the first motor 43 is started to drive the worm gear 44 to rotate. After the worm gear 44 rotates, it drives the worm wheel 42 to rotate. After the worm wheel 42 rotates, it drives the lead screw 41 to rotate. After the lead screw 41 rotates, it drives the slider 3 to slide in the groove of the base 1 through the thread engagement, thereby changing the height of the tension roller 5, which in turn changes the tension of the silicon nitride cast film during winding. This allows the device to adjust the tension on the silicon nitride cast film in real time according to the change in the film roll diameter (such as from the initial mandrel to the full roll), ensuring that the tension of each layer is constant and avoiding excessive tension that could cause the silicon nitride cast film to break, or insufficient tension that could cause it to loosen after winding.
[0030] Furthermore, a buffer roller 6 is movably connected to the base 1, and a buffer assembly 7 is provided on the base 1. The buffer assembly 7 includes a buffer seat 71 and an adjusting seat 72. A slide rail is provided on the base 1, and both the buffer seat 71 and the adjusting seat 72 are slidably connected in the slide rail. The buffer roller 6 is rotatably connected to the buffer seat 71. A threaded rod 75 is rotatably connected in the slide rail. The adjusting seat 72 is threadedly connected to the threaded rod 75. An clearance hole is provided on the buffer seat 71, and the threaded rod 75 passes through the clearance hole. A handle 79 is fixedly connected to one end of the threaded rod 75.
[0031] Specifically, a buffer spring 73 is fixedly connected to the adjusting seat 72, the buffer spring 73 is fixedly connected to the buffer seat 71, a damper 74 is provided inside the buffer spring 73, one end of the damper 74 is fixedly connected to the adjusting seat 72, and the other end of the damper 74 is fixedly connected to the buffer seat 71.
[0032] Furthermore, the buffer assembly 7 also includes a fixing seat 76. A fixing groove is provided on the base 1. The fixing seat 76 is slidably connected in the fixing groove. A threaded hole is provided on the inner wall of the fixing groove. A fixing bolt 77 is threadedly connected in the threaded hole. The fixing bolt 77 is rotatably connected in the fixing seat 76. A rubber pad 78 is fixedly connected on the fixing seat 76.
[0033] Specifically, during the winding process of silicon nitride cast film, collisions or machine malfunctions may cause the silicon nitride cast film to be subjected to excessive instantaneous tension and break. The buffer assembly 7 can buffer the instantaneous tension. When the tension suddenly increases, the buffer roller 6 will compress the buffer spring 73 and the damper 74 and move them into the slide. The compression of the buffer spring 73 and the damper 74 will buffer the tension, thereby preventing the silicon nitride cast film from being stretched and breaking.
[0034] Furthermore, since the thickness of the silicon nitride cast film varies, the tension it can withstand also varies. By rotating the fixing bolt 77, it can be moved through its threaded engagement with the base 1, causing the fixing seat 76 to move. This causes the fixing seat 76 to no longer fix the threaded rod 75. At this time, by rotating the handle 79, the threaded rod 75 can be rotated, causing the adjusting seat 72 to move through its threaded engagement. This changes the preload of the buffer spring 73, allowing the device to be adjusted according to the thickness of the silicon nitride cast film, thus preventing the buffer assembly 7 from responding too quickly or too slowly.
[0035] Furthermore, a take-up roller 8 is rotatably connected to the base 1, and a drive assembly 9 is provided on the base 1. The drive assembly 9 is used to drive the take-up roller 8 to rotate. The drive assembly 9 includes a second motor 91, which is fixedly connected to the base 1. A first gear 92 is fixedly connected to the output end of the second motor 91, and a second gear 93 is fixedly connected to one end of the take-up roller 8. The first gear 92 and the second gear 93 mesh.
[0036] Specifically, the second motor 91 starts and drives the first gear 92 to rotate. After the first gear 92 rotates, it will drive the second gear 93 that meshes with it to rotate, thereby driving the winding roller 8 to rotate, and thus realizing the winding of the silicon nitride cast film.
[0037] The working principle of this utility model is as follows:
[0038] This invention features an adjustment component 4. When winding the silicon nitride cast film, the first motor 43 is activated to drive the worm gear 44 to rotate. The rotation of the worm gear 44 drives the worm wheel 42 to rotate, which in turn drives the lead screw 41 to rotate. The rotation of the lead screw 41, through threaded engagement, causes the slider 3 to slide within the groove of the base 1, thereby changing the height of the tension roller 5 and thus altering the tension of the silicon nitride cast film during winding. This allows the device to adjust the tension on the silicon nitride cast film in real time according to the change in the film roll diameter (from the initial mandrel to the full roll), ensuring constant tension in each layer and preventing excessive tension that could cause the silicon nitride cast film to break, or insufficient tension that could cause it to slack after winding.
[0039] This invention is equipped with a buffer component 7. During the winding process of silicon nitride cast film, collisions or machine malfunctions may cause the silicon nitride cast film to be subjected to excessive instantaneous tension and break. The buffer component 7 can buffer the instantaneous tension. When the tension suddenly increases, the buffer roller 6 will compress the buffer spring 73 and the damper 74 and move them into the slide. The compression of the buffer spring 73 and the damper 74 will buffer the tension and prevent the silicon nitride cast film from being suddenly tightened and breaking.
[0040] This invention allows the fixing bolt 77 to move through its threaded engagement with the base 1, thereby moving the fixing seat 76 and removing the threaded rod 75 from the fixing seat 76. At this point, rotating the handle 79 causes the threaded rod 75 to rotate, which in turn moves the adjusting seat 72 through its threaded engagement. This changes the preload of the buffer spring 73, allowing the device to be adjusted according to the thickness and tension of the silicon nitride cast film, thus preventing the buffer assembly 7 from responding too quickly or too slowly.
[0041] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
