Description

Technical Field

[0001] This utility model belongs to the field of film processing technology, and in particular relates to an oil fume cleaning device for extrusion die heads. Background Technology

[0002] During the extrusion of the film in a molten state from the extrusion die, a large amount of oil fumes are generated due to the film being heated to a molten state at high temperature. Therefore, a connecting pipe with a fan needs to be installed above the extrusion die to suck away the oil fumes. When the high-temperature oil fumes (200-300℃) come into contact with a low-temperature object (such as the inner wall of a range hood), they cool rapidly. The grease liquefies from a gaseous state and adheres to form oil droplets, which adhere to the wall of the connecting pipe. Over time, the oil droplets tend to drip along the wall of the connecting pipe onto the extruded film. A structure is proposed to prevent oil droplets from dripping onto the film. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides an extrusion die oil fume cleaning device, which solves the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an oil fume cleaning device for an extrusion die, comprising a flared pipe, a baffle, a collecting assembly, and an adjusting assembly. The flared pipe is horizontally fixedly connected to the bottom of an exhaust fan connecting pipe. The baffle is inclinedly disposed within the flared pipe, with one side of the baffle extending downwards through the side wall of the flared pipe. The other three sides of the baffle are spaced 3-4 cm away from the inner wall of the flared pipe. Upwardly protruding baffle strips are fixedly connected to both sides of the baffle. Multiple guide grooves are fixedly connected to the upper surface of the flared pipe. The collecting assembly is used to collect oil droplets falling from the baffle. The adjusting assembly is used to adjust the inclination of the baffle.

[0005] Beneficial effects

[0006] This utility model provides an oil fume cleaning device for extrusion die heads, which has the following advantages compared with the prior art:

[0007] 1. During the process of oil fumes being drawn into the exhaust fan connecting pipe, since the baffle is located below the exhaust fan connecting pipe, the oil fumes are drawn into the exhaust fan connecting pipe through the gap between the baffle and the inner wall of the flared pipe, thus avoiding the baffle affecting the oil fume intake. When oil droplets are generated inside the exhaust fan connecting pipe wall, the oil droplets can drip onto the baffle along the inner wall of the exhaust fan connecting pipe. At this time, since the baffle is inclined, the oil droplets can slide down its slope, thus preventing the oil droplets in the pipe from falling onto the membrane. At the same time, the multiple guide grooves on the surface of the baffle can guide the oil droplets, and the baffle strips on both sides of the baffle prevent the oil droplets from sliding to the sides of the baffle. Since the oil fumes will come into contact with the lower surface of the baffle during the process of being drawn in, oil droplets will also be generated on it. However, since the baffle is inclined, the oil droplets generated on its lower surface can also slide down its slope into the collection component for storage. Attached Figure Description

[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 1-4This invention provides an embodiment of an extrusion die oil fume cleaning device, characterized in that it includes a flared pipe 201, a baffle 202, a receiving assembly, and an adjusting assembly. The flared pipe 201 is horizontally fixedly connected to the bottom of the exhaust fan connecting pipe 101. The baffle 202 is inclinedly disposed in the flared pipe 201, with one side of the baffle 202 extending downward through the side wall of the flared pipe 201. The other three sides of the baffle 202 are each 3-4 cm away from the inner wall of the flared pipe 201. Upwardly protruding baffle strips 203 are fixedly connected to both sides of the baffle 202, and multiple guide grooves 204 are fixedly connected to the upper surface of the baffle 202.

[0016] The receiving component is used to receive oil droplets falling from the baffle 202; the adjusting component is used to adjust the tilt of the baffle 202.

[0017] In the above embodiment, during the process of oil fumes being drawn into the exhaust fan connecting pipe 101, since the baffle 202 is located below the exhaust fan connecting pipe 101, the oil fumes are drawn into the exhaust fan connecting pipe 101 through the gap between the baffle 202 and the inner wall of the flared pipe 201, thus avoiding the baffle 202 from affecting the oil fume intake. When oil droplets are generated inside the exhaust fan connecting pipe 101, the oil droplets can drip onto the baffle 202 along the inner wall of the exhaust fan connecting pipe 101. At this time, since the baffle 202 is inclined... Therefore, the oil droplets can slide downwards along its inclined surface, thus preventing the oil droplets in the pipe from falling onto the membrane. At the same time, the multiple guide grooves 204 provided on the surface of the baffle 202 can guide the oil droplets, and the baffle strips 203 provided on both sides of the baffle 202 prevent the oil droplets from sliding to the sides of the baffle 202. Since the oil fumes will come into contact with the lower surface of the baffle 202 during the process of being sucked in, oil droplets will also be generated on it. However, since the baffle 202 is inclined, the oil droplets generated on its lower surface can also slide along its inclined surface into the collection component for storage.

[0018] 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 baffle 202 described in the above embodiments. For example, the baffle 202 is 2-3 times the inner diameter of the exhaust fan connecting pipe 101. The purpose of this setting is to ensure that the oil droplets on the inner wall of the exhaust fan connecting pipe 101 can drip onto the baffle 202.

[0019] Specifically, a plurality of base plates 205 are provided below the baffle 202, and the width of the base plate 205 is greater than the distance between the side of the baffle 202 and the inner wall of the flared tube 201. Since the plurality of base plates 205 are vertically arranged below the gap between the baffle 202 and the flared tube 201, when oil drips in the gap, it will drip onto the base plate 205, thereby further preventing oil from dripping onto the film.

[0020] 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 base plate 205 described in the above embodiments. For example, the end of the base plate 205 away from the inner wall of the flared tube 201 can be set to be inclined upward. The purpose of this setting is to facilitate the collection of dripping water from the inner wall of the flared tube 201 onto the base plate 205.

[0021] Specifically, the adjustment component includes a shaft 206, which is disposed at the upwardly inclined end of the baffle 202 and is fixedly connected to the baffle 202. The shaft 206 is rotatably connected to the flared tube 201.

[0022] In the above embodiment, the user can adjust the tilt of the baffle 202 by rotating the shaft 206. During the rotation of the baffle 202, its end is always directly above the liquid collection tank 207, thereby avoiding the baffle 202 being too tilted, which would prevent the oil droplets attached to the lower surface of the baffle 202 from sliding along its surface into the collection assembly.

[0023] 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 shaft 206 described in the above embodiments. For example, the end of the shaft 206 is provided with a protrusion wrapped with an anti-slip rubber ring. The purpose of this setting is to facilitate the user to manually rotate the shaft 206.

[0024] Specifically, the receiving assembly includes a liquid collection tank 207 and a top rod 208. The liquid collection tank 207 is located directly below the downward inclined end of the baffle 202. The top rod 208 is fixedly connected to the upper surfaces of both sides of the liquid collection tank 207, and the baffle 203 overlaps the upper surface of the top rod 208.

[0025] The disassembly assembly is used to limit and fix the liquid collection tank 207.

[0026] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific liquid collection tank 207 described in the above embodiments. For example, the inner wall of the liquid collection tank 207 is coated with an oleophobic layer. The purpose of this arrangement is to facilitate the discharge of the oil inside the tank in this way, so as to facilitate the cleaning of the liquid collection tank 207.

[0027] In the above embodiment, the oil droplets on the upper and lower surfaces of the baffle 202 slide into the collection tank 207 for storage. At the same time, the user should disassemble the collection tank 207 regularly for cleaning to prevent excessive oil droplets from overflowing. Meanwhile, the top rods 208 provided on both sides of the collection tank 207 can support the baffle 202 to prevent its angle from changing.

[0028] Specifically, the disassembly assembly includes a plug 209, a groove 301, and a guide assembly. Grooves 301 are symmetrically arranged on both sides of the liquid collection tank 207, and the plug 209 is inserted into the groove 301 and fits against the inner wall of the groove 301.

[0029] The guide assembly is used to apply a thrust to the plug 209.

[0030] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific plug 209 described in the above embodiments. For example, the plug 209 is made of hard metal. The purpose of this arrangement is to facilitate the avoidance of its breakage under stress.

[0031] Specifically, the guide assembly includes a spring 302 and a slider 303. The plug 209 is slidably disposed in the slider 303, and the slider 303 is attached to both sides of the exhaust fan connecting pipe 101. The spring 302 is sleeved on the plug 209. The two ends of the spring 302 are fixedly connected to the plug 209 and the slider 303 respectively. The upper end face of the slider 303 is fixedly connected to the output shaft of the cylinder 304, and the cylinder 304 is fixedly connected to the flared pipe 201.

[0032] In the above embodiment, the user can pull the plug 209 laterally to compress the spring 302 fixedly connected to it, thereby allowing the plug 209 to disengage from the groove 301, thus stopping the limiting of the liquid collection tank 207. This allows the user to remove the liquid collection tank 207 from the flared tube 201 to clean the oil stains inside. At the same time, while adjusting the tilt of the baffle 202, the user should activate the cylinder 304, so that the slider 303 fixedly connected to its output shaft slides up or down at a constant speed, thereby adjusting the relative position of the liquid collection tank 207 on the flared tube 201. The baffle 202 is supported and positioned by the top rods 208 on both sides, and the distance between the liquid collection tank 207 and the baffle 202 is maintained.

[0033] 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.

[0034] 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.

[0035] (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.

[0036] (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.

[0037] 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.

[0038] 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.

[0039] 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.
