Description

Technical Field

[0001] This utility model belongs to the field of thin film processing technology, and in particular relates to a thin film edge-cutting structure with threaded advance and retreat. Background Technology

[0002] In the film production process, an edge-cutting structure is required to clamp the two sides of the film and pull the film to both sides. However, the edge-cutting structure cannot precisely control the edge-cutting depth, and it is easy for the edge-cutting to be too shallow, which cannot form an effective clamping and makes the film easy to fall off. A structure that makes it easier to control the edge-cutting depth of the film is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a thin-film edge-cutting structure with threaded advance and retreat, thus solving the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a threaded film edge-cutting structure, comprising sliding rods, two sliding rods symmetrically fixedly connected to both sides of a base, and each sliding rod having a horizontally arranged lead screw, which is rotatably connected to the sliding rod. The end of the lead screw passes through the sliding rod, and each of the two lead screws is threadedly connected to a connecting block, which is slidably connected to the sliding rod. The connecting block on the right side is provided with a clamping assembly, and the connecting block on the other side is provided with a positioning assembly. The clamping assembly is used to clamp the film edge; the positioning assembly is used to guide the film.

[0005] Beneficial effects

[0006] This invention provides a thin-film edge-cutting structure with threaded advance and retraction, which has the following advantages compared with the prior art:

[0007] 1. Users can rotate the knob at the end of the lead screw to make the threaded connecting block on the lead screw start to move linearly along its connection with the slide bar. Since the slide bar has a self-locking effect, it can effectively limit the position of the connecting block. This allows users to flexibly adjust the position of the connecting block as needed, so that the clamping components on it are closer to or further away from the film, so that users can adjust its edge cutting depth.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0015] Please see Figures 1-4 This utility model provides a threaded film edge-cutting structure, comprising a slide rod 201, two slide rods 201 symmetrically fixedly connected to both sides of a base 101, and each of the two slide rods 201 is horizontally provided with a lead screw 202, which is rotatably connected to the slide rod 201. The end of the lead screw 202 passes through the slide rod 201, and each of the two lead screws 202 is threadedly connected with a connecting block 203, which is slidably connected to the slide rod 201. The connecting block 203 on the right side is provided with a clamping component, and the connecting block 203 on the other side is provided with a positioning component.

[0016] The clamping assembly is used to clamp the edge of the film; the positioning assembly is used to guide the film.

[0017] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific lead screw 202 described in the above embodiments. For example, the lead screw 202 should be a lead screw with a self-locking effect. The purpose of this setting is to facilitate the increase of the limiting effect on the threaded connection block 203 on it.

[0018] In the above embodiment, the user can rotate the knob at the end of the lead screw 202 to make the threaded connecting block 203 on the lead screw 202 start to move linearly along its connection with the slide bar 201. Since the slide bar 201 has a self-locking effect, it can effectively limit the position of the connecting block 203. Thus, the user can flexibly adjust the position of the connecting block 203 as needed, so that the clamping component on it is closer to or further away from the film, so that the user can adjust its edge cutting depth.

[0019] Specifically, the clamping assembly includes a base plate 208, a top plate 209, and an adjustment assembly. The base plate 208 is horizontally disposed on the upper side of the corresponding connecting block 203, and the top plate 209 is disposed parallel to the base plate 208. The end of the top plate 209 extends through the base plate 208, and the top plate 209 is slidably connected to the base plate 208.

[0020] The adjustment component is used to adjust the installation position of the base plate 208 and the top plate 209.

[0021] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific top plate 209 and bottom plate 208 described in the above embodiments. For example, the inner sides of the top plate 209 and bottom plate 208 are provided with rubber pads. The purpose of this arrangement is to facilitate the avoidance of film damage.

[0022] In the above embodiment, when the user adjusts the distance between the bottom plate 208 and the top plate 209 and the edge of the film, the edge of the film is located between the bottom plate 208 and the top plate 209. At this time, the user can start the cylinder 301, so that the output end of the cylinder 301 begins to extend. That is, under the action of the cylinder 301, the top plate 209 begins to slide downward, that is, the top plate 209 begins to slide toward the bottom plate 208, thereby clamping the edge of the film between the bottom plate 208 and the top plate 209.

[0023] Specifically, the adjustment assembly includes a connecting plate B205 and a limiting assembly. The connecting plate B205 is fixedly connected to the base plate 208, and the connecting plate B205 is vertically arranged and attached to the side wall of the connecting plate A204. The connecting plate A204 is horizontally fixedly connected to the corresponding connecting block 203. Both the connecting plate A204 and the connecting plate B205 are provided with through grooves. Bolts 206 are inserted through the through grooves, and the other end of the bolts 206 is threadedly connected to a pressure ring 207.

[0024] The limiting component is used to limit the sliding distance of the connecting plate A204.

[0025] In the above embodiment, the user can loosen the pressure ring 207 to stop it from pressing against the surface of the connecting plate B205. At this time, the connecting plate B205 can slide relative to the connecting plate A204. Then, the user can adjust the position of the connecting plate B205 laterally or longitudinally as needed, so that the upper surface of the base plate 208 is in contact with the lower surface of the film. Then, the user can tighten the pressure ring 207 again, so that the bolt 206 and the pressure ring 207 cooperate to clamp the connecting plate A204 and the connecting plate B205 between them, thereby fixing the position of the connecting plate B205.

[0026] Specifically, a cylinder 301 is vertically fixedly connected to the connecting plate B205, and the output end of the cylinder 301 is fixedly connected to the top plate 209.

[0027] Specifically, the positioning component includes a base 302, a roller A303, and an opening component. The base 302 is fixedly connected to the corresponding connecting block 203. The roller A303 is rotatably connected to the base 302, and the central axis of the roller A303 is perpendicular to the base 302. A roller B304 is arranged parallel to the roller A303.

[0028] The opening assembly is used to ensure that rollers B304 and A303 are tightly attached to the film between them.

[0029] Specifically, the opening assembly includes a bracket 305 and a motor 306. The roller B304 is rotatably connected to the bracket 305, and the bracket 305 is fixedly connected to the output shaft of the motor 306. The motor 306 is fixedly connected to the base 302.

[0030] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific motor 306 described in the above embodiments. For example, the motor 306 should be a motor with a self-locking effect. The purpose of this setting is to facilitate the increase of the limiting effect on the roller B304 through this setting.

[0031] In the above embodiment, the user can slide the corresponding lead screw 202 laterally by the positioning component, so that the roller A303 is attached to the underside of the film. Then the user can start the motor 306, so that the bracket 305 fixedly connected to its output shaft rotates at a constant speed. At this time, the roller B304 begins to move toward the roller A303 until the roller B304 is parallel to the roller A303. At this time, the film is clamped between them. Since both the roller A303 and the roller B304 are rotating, they will not interfere with the movement of the film.

[0032] Specifically, the limiting component includes a rod 307 and a spring 308. The end of the rod 307 is slidably disposed in the cavity of the connecting plate A204, and the rod 307 extends through the connecting plate A204. The spring 308 is fixedly connected to the rod 307, and the other end of the spring 308 is fixedly connected to the connecting plate A204.

[0033] Specifically, the insertion rod 307 abuts against the groove of the positioning block 309, and the positioning block 309 is slidably disposed on the corresponding slide rod 201, and the positioning block 309 is threaded with a bolt.

[0034] In the above embodiment, the user can adjust the relative position of the positioning block 309 on the slide rod 201 by moving the positioning block 309 laterally, and then tighten the bolt on the positioning block 309 to make it press against the slide rod 201, thereby fixing the relative position of the positioning block 309 on the slide rod 201. When the user rotates the lead screw 202 in the opposite direction to make the connecting block 203 retract, the insertion rod 307 can slide along the slope on the side of the positioning block 309 and get into the groove of the positioning block 309. At this time, the connecting block 203 cannot continue to slide, thus making it easier for the user to control the retraction distance of the connecting block 203.

[0035] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0036] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0037] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0038] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0039] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0040] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
