Description

Technical Field

[0001] This utility model belongs to the field of degreasing technology, and in particular relates to a degreasing mechanism for the longitudinal stretching stage of thin film production. Background Technology

[0002] When stretching films longitudinally, lubricating oil or release agent (such as silicone oil) is required to reduce equipment friction. If the subsequent cleaning is not thorough, residual lubricant will seep out and form oil droplets during the stretching process. Therefore, the oil on the film needs to be scraped off onto the screen below and dripped through the mesh of the screen into the oil collection box below. After gathering on the screen, it drips into the oil collection box below. However, when the oil droplets fall into the oil collection box, splashing is likely to occur. An oil removal mechanism that can avoid oil droplet splashing is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides an oil removal mechanism for the longitudinal stretching stage of thin film production, thus solving the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an oil removal mechanism for the longitudinal stretching stage of film production, comprising two screen plates and a scraping assembly. One end of each of the two screen plates is fixedly connected to the inner walls of both sides of the screen plate, and the other ends of the two screen plates are inclined downwards and fixedly connected to each other. A guide plate is inclinedly arranged below the screen plate, and the two guide plates are fixedly connected to the center line of the frame. The other ends of the two guide plates are inclined downwards and extend into the liquid collection tank, and the ends of the guide plates do not contact the inner wall of the liquid collection tank. The liquid collection tank is fixedly connected to the bottom of the frame. The scraping assembly is used to scrape the oil droplets attached to the screen plates.

[0005] Beneficial effects

[0006] This invention provides an oil removal mechanism for the longitudinal stretching stage of thin film production, which has the following advantages compared with the prior art:

[0007] 1. Since the two screens are inclined in the frame, when oil droplets fall on their surface and adhere, they can slide downwards along the incline. During this sliding process, the oil can flow out through the mesh holes, thus preventing the oil droplets from adhering to the screen surface. When the oil droplets drip from the screens, they will drip onto the guide plate below them. At this time, the oil droplets begin to slide along the incline of the guide plate into the collection tank. Since there is a certain distance between the guide plate and the side wall of the collection tank, the oil droplets can flow into the collection tank along the gap, thus preventing the oil droplets from dripping directly into the collection tank and splashing.

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 invention provides an embodiment of an oil removal mechanism for the longitudinal stretching stage of film production, comprising two screen plates 201 and a cleaning assembly. One end of each of the two screen plates 201 is fixedly connected to the inner walls of both sides of the screen plate 201, and the other ends of the two screen plates 201 are inclined downward and fixedly connected to each other. A guide plate 202 is inclinedly arranged below the screen plate 201. The two guide plates 202 are fixedly connected to the center line of the frame 101, and the other ends of the two guide plates 202 are inclined downward and extend into the liquid collection tank 203. The ends of the guide plates 202 do not contact the inner wall of the liquid collection tank 203. The liquid collection tank 203 is fixedly connected to the bottom of the frame 101.

[0016] The cleaning component is used to clean oil droplets adhering to the mesh plate 201.

[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 screen plate 201 described in the above embodiments. For example, the screen plate 201 may be provided with an oleophobic coating. The purpose of this setting is to facilitate the reduction of oil droplet adhesion on it.

[0018] In the above embodiment, since the two mesh plates 201 are inclinedly arranged in the frame 101, when oil droplets fall on their surface and adhere, they can slide downwards along their inclined surfaces. During the sliding process, the oil can flow out through the mesh holes, thus preventing oil droplets from adhering to the surface of the mesh plate 201. When the oil droplets drip from the mesh plate 201, they will drip onto the guide plate 202 below it. At this time, the oil droplets begin to slide along the inclined surface of the guide plate 202 into the collection tank 203. At the same time, since there is a certain distance between the guide plate 202 and the side wall of the collection tank 203, the oil droplets can flow into the collection tank 203 along the gap, thus preventing the oil droplets from directly dripping into the collection tank 203 and causing splashing.

[0019] Specifically, baffles 204 are fixedly connected to both sides of the guide plate 202, and the upper surface of the liquid collection tank 203 is 4-5 cm higher than the plane of the guide plate 202. Since baffles 204 are provided on both sides of the guide plate 202, oil droplets can be prevented from sliding off from both ends of the guide plate 202 as they slide along its inclined surface.

[0020] Specifically, the cleaning and scraping assembly includes two push plates 205, a pressing assembly, and a driving assembly. One end of each of the two push plates 205 is slidably connected to a slide rod 305, and the slide rod 305 is horizontally fixed to one side of the frame 101. Each of the two push plates 205 has a scraper 206 vertically arranged on the side that is close to each other, and the lower end face of the scraper 206 is attached to the upper surface of the mesh plate 201.

[0021] The pressing component is used to make the lower end face of the scraper 206 stick tightly to the upper surface of the mesh plate 201, and the driving component is used to make the two push plates 205 slide horizontally.

[0022] 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 scraper 206 described in the above embodiments. For example, the lower end face of the scraper 206 may be wrapped with a soft rubber pad. The purpose of this arrangement is to make it adhere tightly to the upper surface of the mesh plate 201 through the soft rubber pad, thereby increasing the scraping effect on the oil droplets on it.

[0023] In the above embodiment, since the scraper 206 is vertically arranged on the upper surface of the mesh plate 201 and its lower end is attached to the upper surface of the mesh plate 201, when the push plate 205 starts to slide under the action of the drive component, the scraper 206 can slide synchronously, and the scraper 206 can always be tightly attached to the upper surface of the mesh plate 201 by the pressing component. Thus, during the process of the scraper 206 sliding against the surface of the mesh plate 201, the upper surface of the mesh plate 201 can be cleaned and scraped, so that the oil droplets attached to its surface can drip off, thereby further preventing oil droplet adhesion.

[0024] Specifically, the pressing component includes guide rods 207, a plurality of guide rods 207 are vertically fixedly connected in the push plate 205, and the scraper 206 is slidably connected to the guide rods 207. A spring 209 is sleeved on the guide rods 207, and the two ends of the spring 209 are fixedly connected to the scraper 206 and the push plate 205 respectively.

[0025] 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 spring 209 described in the above embodiments. For example, the spring 209 always provides traction force to the scraper 206, so that it is tightly attached to the upper surface of the mesh plate 201.

[0026] In the above embodiment, since the spring 209 is disposed between the scraper 206 and the push plate 205, the spring 209 can apply vertical downward pressure to the scraper 206 under the action of the tension, so that the scraper 206 is in close contact with the upper surface of the screen plate 201. During the sliding process of the push plate 205, the scraper 206 slides against the upper surface of the screen plate 201 to assist in cleaning the oil droplets on the upper surface of the screen plate 201.

[0027] Specifically, each of the push plates 205 is provided with a protective plate 301, and the protective plate 301 is fixedly connected to the upper surface of the frame 101 at an angle, and the push plate 205 is directly below the protective plate 301 when it is in the initial state.

[0028] In the above embodiment, since the push plate 205 is located directly below the protective plate 301 in the initial state, oil droplets can be effectively prevented from dripping onto the push plate 205. Thus, when the push plate 205 starts to slide through the drive assembly, the oil droplets on the mesh plate 201 can be effectively cleaned.

[0029] Specifically, the drive assembly includes a left-hand lead screw 302 and a right-hand lead screw 303. Two push plates 205 are threadedly connected to the left-hand lead screw 302 and the right-hand lead screw 303, respectively. The left-hand lead screw 302 and the right-hand lead screw 303 are horizontally arranged on the side of the frame 101, and the ends of the left-hand lead screw 302 and the right-hand lead screw 303 that are close to each other are fixedly connected to each other. The left-hand lead screw 302 and the right-hand lead screw 303 are rotatably connected to the frame 101.

[0030] Specifically, one end of the right-hand screw 303 extends through the side wall of the frame 101, and a knob 304 is fixedly connected to it.

[0031] In the above embodiment, the user can manually rotate the knob 304 to make the right-hand lead screw 303 and the left-hand lead screw 302, which are fixedly connected at the axis, rotate synchronously. At this time, the two push plates 205 connected to the screws on the knob 201 begin to slide in opposite directions, thereby cleaning the oil droplets on the upper surface of the screen plate 201.

[0032] 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.

[0033] 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.

[0034] (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.

[0035] (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.

[0036] 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.

[0037] 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.

[0038] 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.
