Description

Technical Field

[0001] This utility model relates to the field of oil stain cleaning structure technology, and more specifically, to a polyester film horizontal zipper clamp oil stain cleaning device. Background Technology

[0002] The finished rolls of polyester film have extremely strict requirements regarding defects, especially oil stains. Oil stains can easily reduce the adhesion of inks during the printing process, causing white spots in the printing; or damage the interfacial bonding between the adhesive or coating and the film during the metallization and lamination processes, leading to delamination of the laminated film (peel strength reduction ≥30%), pinholes in the metallized layer, uneven gloss, etc.; in the bag making process, it can easily lead to uneven strength in the heat-sealing area (heat-sealing strength difference can reach 20%), affecting production capacity; more serious issues, such as in electronic films and window films, will lead to decreased product performance and non-compliance. Therefore, in the polyester film industry, finished products found to have oil stains will be downgraded, and severely contaminated products will be scrapped directly. Oil stains mainly appear in the transverse stretching (TDO) area of ​​the film. After passing through the high-temperature area, the chain clamp lubricating oil evaporates into oil vapor and eventually adheres to the chain clamp, forming oil stains. During subsequent chain clamp operation, the oil stains on the chain clamp are splashed onto the film surface, thus affecting the quality of the film.

[0003] Existing instruments for removing oil stains from the surface of chain clamps mostly use external ventilation to suck the oil stains on the chain clamps into the oil suction pipe at the TDO outlet. This technology has disadvantages such as difficulty in replacing pipes and equipment, inefficient cleaning effect, and difficulty in cleaning residual oil stains inside the pipes. Utility Model Content

[0004] (a) Technical problems to be solved The technical problem to be solved by this utility model is that the existing technology has problems such as difficulty in replacing oil suction pipes, insufficient cleaning efficiency, and difficulty in cleaning residual oil stains inside the pipes.

[0005] (II) Technical Solution To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a device for cleaning oil stains from a polyester film horizontal zipper clamp, including a zipper cover, a first half-shell, a second half-shell, a cleaning sponge, and a clamp; the first half-shell is fixedly connected to the zipper cover; the second half-shell is detachably connected to the first half-shell, and a clamping cavity is formed between the first half-shell and the second half-shell; the cleaning sponge is disposed in the clamping cavity; the clamp is sleeved on the outer periphery of the first half-shell and the second half-shell, and the clamp is used to fasten the first half-shell and the second half-shell.

[0006] Preferably, the cleaning sponge comprises a wear-resistant outer layer and an oil-absorbing inner core, the wear-resistant outer layer being disposed on the surface of the oil-absorbing inner core, and the porosity of the wear-resistant outer layer being 60%. The cleaning sponge adopts a composite structure, comprising a wear-resistant outer layer and an oil-absorbing inner core. The wear-resistant outer layer covers the outer surface of the oil-absorbing inner core, and its porosity is preferably 60%. This structure ensures both the durability of the sponge surface when rubbing against the chain clamp and sufficient internal space to absorb and store oil stains.

[0007] Preferably, the thickness of the wear-resistant surface layer is 50 mm. The thickness of the wear-resistant surface layer is preferably 50 mm to achieve the best balance between wear resistance and oil absorption efficiency.

[0008] Preferably, the wear-resistant surface layer is polyurethane sponge, and the oil-absorbing core is polypropylene sponge. The wear-resistant surface layer is preferably made of polyurethane sponge because it has excellent wear resistance and resilience; the oil-absorbing core is preferably made of polypropylene sponge because it has excellent oleophilic and hydrophobic properties and a high oil absorption rate.

[0009] Preferably, the chain clamp cover includes a side wall panel, a bottom plate, and a top plate. The bottom plate and the top plate are arranged in parallel. One end of the side wall panel is fixedly connected to the top plate, and the other end of the side wall panel is fixedly connected to the bottom plate. The first half-shell is fixedly connected to the side wall panel. The chain clamp cover includes a side wall panel and a bottom plate. The side wall panel, the bottom plate, and the top plate are respectively perpendicularly arranged and fixedly connected (e.g., by welding or bolting) to form a "[" shaped support structure. The first half-shell is fixedly connected to the inner side of the side wall panel.

[0010] Preferably, the side wall panel is provided with a snap-fit. This snap-fit ​​can be used to conveniently install the entire device onto a specific bracket or position on the production line, enabling quick assembly and disassembly.

[0011] Preferably, the outer periphery of the first half-shell has a first groove, and the outer periphery of the second half-shell has a second groove. The first groove and the second groove communicate to form an annular groove, which is used to accommodate the clamp. A semi-circular first groove is formed on the outer periphery of the first half-shell, and a corresponding semi-circular second groove is formed on the outer periphery of the second half-shell. When the first half-shell and the second half-shell are mated, the first groove and the second groove together form a complete annular groove. The clamp is precisely accommodated and secured within this annular groove, ensuring the stability and alignment of the connection.

[0012] Preferably, the first half-shell has a connecting protrusion, and the second half-shell has a connecting groove. The connecting protrusion engages with the connecting groove. Specifically, the connecting protrusion can be provided on the mating end face of the first half-shell, and a corresponding connecting groove can be provided on the mating end face of the second half-shell; or vice versa. The engagement of the protrusion and the groove achieves the initial positioning of the two half-shells, facilitating the subsequent installation of the clamps.

[0013] Alternatively, the first half-shell may have a connecting groove, and the second half-shell may have a connecting protrusion, the connecting protrusion being engaged with the connecting groove.

[0014] Preferably, both the first half-shell and the second half-shell are semi-cylindrical tubular.

[0015] Preferably, the length of the clamping cavity is 100mm, and the length of the cleaning sponge is 130mm. This design causes the end of the cleaning sponge to protrude approximately 30mm from the clamping cavity, forming a "cantilever" structure. This accommodates minor swaying of the chain clamp within a certain range while ensuring that the chain clamp remains in constant contact with the effective part of the cleaning sponge, thus improving the reliability and fault tolerance of the cleaning process.

[0016] (III) Beneficial Effects The above-mentioned technical solution of this utility model has at least the following advantages: 1. Cleaning efficiency and direct: Using a sponge to wipe, it directly contacts and wipes away oil stains on the surface of the chain clamp, effectively removing already attached oil stains.

[0017] 2. Convenient maintenance and replacement: With the clamp and detachable second half shell design, the clamping cavity can be quickly opened and the consumable cleaning sponge can be replaced without disassembling the entire device, which greatly reduces maintenance time and labor intensity.

[0018] 3. No secondary pollution: Oil stains are absorbed and stored inside the cleaning sponge, eliminating the problem of oil accumulation in pipes that is difficult to clean. Replaced sponges can be centrally disposed of, preventing secondary pollution inside the equipment.

[0019] 4. Simple and reliable structure: The overall structure is simple with few parts. It is firmly connected by clamps and snap-fit ​​positioning, ensuring accurate installation and stable operation.

[0020] 5. Good adaptability: The slightly longer design of the cleaning sponge gives it a certain elasticity and compensation ability, which can adapt to the fluctuations in the operation of the chain clamp and ensure continuous and effective cleaning contact.

[0025] To make the technical problem to be solved, the technical solution, and the beneficial effects 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.

[0026] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be located directly on or indirectly on the other component. When a component is referred to as "connected to" another component, it can be directly or indirectly connected to the other component.

They are only for the convenience of describing this utility model and do not indicate that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating relative importance or the number of technical features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. The specific implementation of this utility model is described in more detail below with reference to specific embodiments: like Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment provides a polyester film horizontal zipper clamp oil cleaning device, including a zipper cover 1, a first half-shell 2, a second half-shell 3, a cleaning sponge 4, and a clamp 5; the first half-shell 2 is fixedly connected to the zipper cover 1; the second half-shell 3 is detachably connected to the first half-shell 2, and the first half-shell 2 and the second half-shell 3 together form a clamping cavity; the cleaning sponge 4 is disposed in the clamping cavity; the clamp 5 is sleeved on the outer periphery of the first half-shell 2 and the second half-shell 3, and the clamp 5 is used to fasten the connection between the first half-shell 2 and the second half-shell 3.

[0029] The main reasons for oil contamination on polyester film rolls include untimely external ventilation in the TDO (Thoroughly Stretched Area), incomplete suction leading to internal accumulation, and insufficient viscosity or excessive volatility of the lubricating oil at high temperatures, causing oil atomization and condensation upon cooling, adhering to the chain clamp. The TDO is divided into a preheating zone, stretching zone, setting zone, and cooling zone. The external ventilation is located at the TDO inlet, before the preheating zone. Furthermore, the chain movement and temperature fluctuations between the preheating and stretching zones are significant, easily leading to lubricating oil atomization. Therefore, the polyester film stretching chain clamp cleaning device provided in this embodiment can be added to the preheating and stretching section after the external ventilation to help absorb and remove oil stains and oil mist. Specifically, the clamp 5 is a 304 stainless steel spring clamp with a width of 15mm and a working pressure ≥1.5MPa. The cleaning sponge 4, after being pre-compressed by 10%-15%, allows the first half-shell 2 and the second half-shell 3 to fix it in place.

[0030] As one of the optional embodiments of this example, the cleaning sponge 4 includes a wear-resistant surface layer 41 and an oil-absorbing inner core 42. The wear-resistant surface layer 41 is disposed on the surface of the oil-absorbing inner core 42, and the porosity of the wear-resistant surface layer 41 is 60%.

[0031] As one of the optional embodiments of this example, the thickness of the wear-resistant surface layer 41 is 50 mm.

[0032] As one of the optional embodiments of this example, the wear-resistant surface layer 41 is made of polyurethane sponge, and the oil-absorbing inner core 42 is made of polypropylene sponge.

[0033] As one of the optional embodiments of this example, the chain clamp cover 1 includes a side wall plate 11, a bottom plate 12 and a top plate 13. The bottom plate 12 and the top plate 13 are arranged in parallel. One end of the side wall plate 11 is fixedly connected to the top plate 13, and the other end of the side wall plate 11 is fixedly connected to the bottom plate 12. The first half-shell 2 is fixedly connected to the side wall plate 11.

[0034] As one of the optional embodiments of this example, the side wall panel 11 is provided with a buckle. Specifically, the buckle can be in the form of magnetic fixing, mechanical fixing, or adhesive connection.

[0035] As one of the optional implementations of this embodiment, the outer periphery of the first half-shell 2 is provided with a first slot 21, and the outer periphery of the second half-shell 3 is provided with a second slot 31. The first slot 21 and the second slot 31 are connected to form an annular groove, which is used to accommodate the clamp 5.

[0036] As one of the optional embodiments of this example, the first half-shell 2 is provided with a connecting groove 22, and the second half-shell 3 is provided with a connecting protrusion 32, which is engaged with the connecting groove 22. In another embodiment, the first half-shell 2 is provided with a connecting protrusion, and the second half-shell 3 is provided with a connecting groove, with the connecting protrusion engaging with the connecting groove.

[0037] As one of the optional embodiments of this example, both the first half-shell 2 and the second half-shell 3 are semi-cylindrical tubular.

[0038] As one of the optional embodiments of this example, the length of the clamping cavity is 100mm and the length of the cleaning sponge 4 is 130mm.

[0039] Specifically, the chain clamp housing 1, serving as the mounting base of the device, is welded together from a side wall plate 11, a bottom plate 12, and a top plate 13, forming a "[" shape. A buckle 121 is installed on the bottom plate 12 to facilitate fixing the entire device to a suitable position on the production line. The first half-shell 2 is a semi-cylindrical tubular shell, with its flat side welded and fixed to the side wall plate 11 of the chain clamp housing 1. The second half-shell 3 is also a semi-cylindrical tubular shell, its dimensions matching those of the first half-shell 2. A connecting groove 22 is provided on the mating edge of the first half-shell 2, and a connecting protrusion 32 is provided on the corresponding edge of the second half-shell 3. During installation, the connecting protrusion 32 is aligned and inserted into the connecting groove 22 to achieve initial alignment and connection of the two half-shells. Of course, the positions of the protrusion and the groove can be interchanged. When the first half-shell 2 and the second half-shell 3 are mated, they together form a cylindrical clamping cavity with an internal axial length of 100mm. A cleaning sponge 4 is placed inside this clamping cavity. After assembly, the entire component is placed inside the outer shell of the chain clamp, so that the top plate abuts against the top side of the shell and the bottom plate abuts against the bottom of the shell, thus locking and fixing the component inside the shell. In this embodiment, the cleaning sponge 4 has a composite structure. Its core is a cylindrical oil-absorbing inner core 42 made of highly absorbent polypropylene sponge. A wear-resistant surface layer 41, made of wear-resistant polyurethane sponge with a thickness of approximately 50mm and a porosity of approximately 60%, is wrapped around the outer periphery of the oil-absorbing inner core 42. The total length of the cleaning sponge 4 is designed to be 130mm, 30mm longer than the clamping cavity. After installation, the end of the cleaning sponge 4 extends approximately 30mm beyond the clamping cavity. A semi-annular first groove 21 is formed in the middle of the outer wall of the first half-shell 2, and a semi-annular second groove 31 is formed at a corresponding position on the outer wall of the second half-shell 3. After the two half-shells are joined, the first groove 21 and the second groove 31 form a complete annular groove. The clamp 5 (such as a common hose clamp) is embedded and fastened in the annular groove, thereby firmly locking the first half shell 2 and the second half shell 3 together and pressing the cleaning sponge 4 tightly into the clamping cavity.

[0040] Working principle: During installation, the device is fixed to the running path of the chain clamp on the side wall plate 11 of the chain clamp housing 1, and its position is adjusted so that the cleaning sponge 4 comes into contact with the chain clamp. When the production line starts and the chain clamp runs continuously, its surface will continuously rub against the cleaning sponge 4. The wear-resistant surface layer 41 of the cleaning sponge 4 effectively scrapes away the oil stains on the surface of the chain clamp, which are quickly absorbed and stored by the oil-absorbing core 42 underneath. When the cleaning sponge 4 is saturated and needs to be replaced, simply loosen the clamp 5, gently pry open the second half of the housing 3, remove the old cleaning sponge 4, replace it with a new cleaning sponge 4, then close the second half of the housing 3 and retighten the clamp 5. The entire replacement process is simple and quick, without the need to disassemble the entire device, greatly facilitating the maintenance of the equipment.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
