Description

Technical Field

[0001] This utility model relates to the field of thin film stretching production technology, and in particular to an integrated device for track cooling and lubrication. Background Technology

[0002] Biaxially oriented plastic film (BOPF) is a processing technology that began to be industrialized in the 1970s. BOPF is a general term for plastic films produced by biaxial stretching (or biaxial orientation). Films produced by biaxial stretching equipment are mostly used in packaging, electrical materials, photosensitive materials, agriculture, building decoration, and daily necessities. BOPF has developed rapidly in the last decade and has become a major packaging material for various high-performance packaging films.

[0003] The key component of the biaxial stretching equipment, the transverse stretching device, primarily performs transverse stretching of the film. During the transverse stretching process, the stretching chain clamp assembly moves at high speed along the track. Because the vertical track plate and the stretching chain clamp assembly are dynamically supported, relative sliding occurs between them, requiring the addition of lubricant. The high-speed movement of the stretching chain clamp on the track during transverse stretching generates a large amount of heat, which must be cooled. In existing technologies, the heat generated by the stretching chain clamp and the track, as well as the lubrication issues, are handled by two separate systems: a cooling unit and a lubrication unit. These systems involve numerous components such as temperature control, piping, lubrication stations, and collection devices. Their operation makes the biaxial stretching production line inefficient and complex, and also introduces a series of problems for subsequent use and maintenance. Utility Model Content

[0023] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Various examples are provided by way of explanation and not by way of limitation. In fact, those skilled in the art will recognize that modifications and variations can be made to the present application without departing from the scope or spirit thereof. For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. Therefore, it is desirable that the present application encompass such modifications and variations that fall within the scope of the appended claims and their equivalents.

They are used only for the convenience of describing this application and do not require that this application be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application. The terms "connected," "linked," and "set up" used in this application should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0025] like Figures 1-4 As shown, an integrated device for track cooling and lubrication includes a vertical rail plate 2 connected to a moving mechanism 101 of a chain clamp assembly 1. The integrated device also includes a mixer 3. Compressed air and lubricating medium are input at the input end of the mixer 3, and cooling and lubricating medium is output at the output end of the mixer 3. A medium flow channel 201 is provided inside the vertical rail plate 2, and a release hole 202 communicating with the medium flow channel 201 is provided on the side wall of the vertical rail plate 2. The output end of the mixer 3 is connected to the medium flow channel 201 through a conveying pipeline 4.

[0026] This invention is mainly applied to the vertical rail plate 2 in the transverse tension section of a biaxial stretching device, primarily for lubricating and cooling the relative movement between the moving mechanism 101 of the chain clamp assembly 1 and the vertical rail plate 2. In the prior art, the moving mechanism 101 of the chain clamp assembly 1 varies widely. This invention is applicable to various types of moving mechanisms 101 in the prior art, including rolling (roller, bearing) moving mechanisms and sliding (slider) moving mechanisms. The cooling and lubricating medium is a mixture of compressed air and a lubricating medium; preferably, lubricating oil is selected as the lubricating medium in this invention. By mixing compressed air with the lubricating medium, it is ensured that the lubricating medium is quickly released from the release hole 202 and adheres to the surface of the component requiring cooling and lubrication to achieve lubrication. The introduction of compressed air can quickly remove the heat generated by the chain clamp assembly 1 running at high speed on the track through convective heat transfer.

[0027] The existing mixer 3 only requires merging the pipes for compressed air and lubricating medium to meet the output requirements of the cooling lubricating medium. An improvement to mixer 3 is presented below:

[0028] The adaptive mixer is equipped with intelligent sensors and a microprocessor. These intelligent sensors monitor parameters such as compressed air pressure, temperature, humidity, and the viscosity and flow rate of the lubricating medium in real time. Based on preset algorithms and real-time monitoring data, the microprocessor automatically adjusts the mixing ratio of compressed air and lubricating medium by controlling the pipe diameter or the opening and closing of multiple input pipes to adapt to the cooling and lubrication requirements under different operating conditions. For example, under high-temperature, high-load conditions, the proportion of lubricating medium is increased to enhance lubrication, while the compressed air pressure is appropriately increased to improve cooling efficiency; under low-temperature, low-load conditions, the proportion of lubricating medium is reduced accordingly to avoid over-lubrication, waste, and pollution. The adaptive mixer can precisely control the composition of the cooling and lubricating medium according to actual operating conditions, improving the accuracy of cooling and lubrication effects, extending the service life of key equipment components, reducing equipment failures caused by insufficient or excessive lubrication, or untimely cooling, thereby improving production efficiency and reducing maintenance costs.

[0029] In one specific embodiment of this utility model, the medium flow channel 201 includes at least one horizontal medium flow channel 2011 and multiple vertical medium flow channels 2012, the release hole 202 is connected to the vertical medium flow channel 2012, and the conveying pipeline 4 is connected to the horizontal medium flow channel 2011.

[0030] There are many specific shape design schemes for the medium flow channel 201. This utility model provides a technical solution with lower processing difficulty. In addition to the "one horizontal and multiple vertical" scheme mentioned above, it can also be "multiple horizontal and one vertical" (in which case the release hole 202 is connected to the horizontal medium flow channel 2011 and the conveying pipe 4 is connected to the vertical medium flow channel 2012) or "multiple horizontal and multiple vertical" (in which case the release hole 202 is connected to the horizontal medium flow channel 2011 and / or the vertical medium flow channel 2012 and the conveying pipe 4 is connected to the horizontal medium flow channel 2011 and / or the vertical medium flow channel 2012).

[0031] By machining a transverse medium flow channel 2011 and a vertical medium flow channel 2012 inside the vertical rail plate 2, and distributing several release holes 202 (or oil seepage holes, oil spray holes) on the left and / or right sides of the vertical rail plate 2, the cooling and lubricating medium enters the contact sliding surface between the moving mechanism 101 and the track through the release holes 202 to generate a lubricating effect. At the same time, the rapid flow of compressed air carries away the heat generated by friction.

[0032] In the specific design, depending on the length of the vertical rail plate 2, the connection interface between the conveying pipeline 4 and the transverse medium flow channel 2011 can be set to multiple and arranged at appropriate intervals.

[0033] In one specific embodiment of this utility model, the vertical rail plate 2 is connected to the upper frame 501 of the track frame 5. The upper frame 501 is connected to the lower frame 503 through the vertical frame 502. The lower frame 503 is provided with a recycling hole 5031, and a collection tray 6 is provided below the recycling hole 5031.

[0034] The existing track frame 5 has various shapes and structures. This utility model provides a design scheme for an I-shaped track frame. The vertical rail plate 2 can be connected to either the upper frame 501 or the lower frame 503. Waste liquid and exhaust gas from cooling and lubrication are collected in the collection tray 6 through the recovery holes 5031 provided on the track frame 5 for recycling.

[0035] In a specific embodiment of this utility model, the chain clamp assembly 1 is fully distributed on the side of the track frame 5, and the lower frame 503 is provided with a supporting flat rail 5032 on the upper side. The chain clamp assembly 1 forms a first sealed chamber 504 with the upper frame 501, the vertical frame 502, the lower frame 503 and the supporting flat rail 5032. The collection tray 6 wraps the lower frame 503, and a second sealed chamber 505 is formed between the collection tray 6 and the lower frame 503. The first sealed chamber 504 and the second sealed chamber 505 are connected through the recycling hole 5031.

[0036] In this embodiment, the components requiring cooling and lubrication include the moving mechanism 101, the vertical rail plate 2 (outer side), and the support rail 5032. However, some existing film transverse stretching machines do not have a support rail, and the moving mechanism is only connected to the vertical rail plate. For models without a support rail, the sealed chamber is formed by connecting the chain clamp assembly, the upper frame, the vertical frame, and the lower frame.

[0037] In its specific design, the collection tray 6 has a slope biased to one side to facilitate waste liquid flow. Due to the small gaps between adjacent chain clamp assemblies 1 and the connection between the chain clamp assembly 1 and the track frame 5, the sealing chamber 504 is not strictly an absolute seal but a relative seal. However, this relative seal effectively reduces the leakage of compressed air and lubricating medium from the chain clamp assembly 1. Thanks to the presence of the recovery hole 5031 and the second sealing chamber 505, the waste liquid and compressed air in the first sealing chamber 504 can be smoothly discharged into the collection tray 6.

[0038] In one specific embodiment of this utility model, the collection tray 6 is connected to the recycling processing device 8 via the recycling pipeline 7.

[0039] The cooling and lubricating medium, having completed its lubrication and cooling functions, sequentially passes through the collection tray 6 and the recovery pipeline 7 into the recovery and processing device 8 for collection and processing. In its specific design, the recovery and processing device 8 can achieve gas-liquid separation. A small amount of lubricating medium will be present in the recovered gas. Therefore, from the perspective of resource conservation, the recovered gas can be reused to produce compressed air, and the recovered liquid can be reused to produce lubricating medium.

[0040] There are many types of recycling and processing devices in the existing technology. The following is an improvement scheme for recycling and processing devices:

[0041] The recycling and treatment unit employs an adaptive multi-stage separation structure. First, a primary separation unit combining centrifugal force and gravity automatically adjusts the centrifugal force and separation angle based on parameters such as flow rate, temperature, and pressure of the incoming waste liquid and gas, rapidly separating larger particles of impurities and some liquid lubricating media. Next, a secondary separation unit based on membrane separation technology automatically adjusts the membrane pore size according to the composition and concentration of the passing medium, precisely separating particles and small molecules of different sizes, ensuring preliminary purification of the gas and liquid. Finally, a deep purification unit utilizes the synergistic effect of adsorbents and catalysts to thoroughly remove remaining trace impurities and harmful substances. For residual lubricating media in the waste liquid, a highly efficient adsorbent can adsorb and recover it. This adaptive multi-stage separation technology can automatically optimize the separation effect according to different operating conditions and changes in the composition of the cooling and lubricating media, significantly improving the efficiency and quality of recycling and treatment. Compared to traditional fixed-parameter separation units, it can more effectively recycle resources, reduce waste emissions, and minimize environmental impact. Meanwhile, due to the better separation effect, the recovered gas and liquid have higher purity and can be directly reused in the system without complicated subsequent processing, which can reduce production costs and improve the operational stability and reliability of the entire system.

[0042] In one specific embodiment of this utility model, the recovery pipeline 7 is equipped with an induced draft fan.

[0043] Since the track frame 5 and the collection tray 6 form a relatively sealed space—sealed chamber 2 505, a negative pressure can be created between the sealed chamber 2 505 and the collection pipeline 7 by installing an induced draft fan in the recovery pipeline 7 for the gas in the cooling and lubricating medium, thereby improving the collection efficiency of the used cooling and lubricating medium.

[0044] In one specific embodiment of this utility model, the conveying pipeline 4 is equipped with a conveying fan.

[0045] During the transportation process, the necessary conveying fans can be set up according to the pipeline layout to maintain the speed and pressure of the cooling and lubricating medium entering the vertical rail plate 2.

[0046] In one specific embodiment of this utility model, compressed air is generated by air compressor 9 and delivered to mixer 3, and lubricating medium is delivered to mixer 3 by delivery pump 10.

[0047] In existing technologies, compressed air can be produced using either dedicated air compressors or commercially available compressed air from factories. In this embodiment, for further ease of control, a dedicated air compressor 9 is used to produce compressed air, and the pressure of the compressed air produced by the air compressor 9 can be adjusted by the control system. Using compressed air as a carrier, the compressed air is mixed with a lubricating medium to form a cooling and lubricating medium, which is then conveyed into the medium flow channel 201 of the vertical rail plate 2 via the delivery pipeline 4. The cooling and lubricating medium produced in the mixer 3 is a mixture of compressed air and a lubricating medium, wherein the concentration of the lubricating medium can be adjusted by the delivery pump 10 according to the actual operating effect of the equipment or feedback from monitoring signals.

[0048] In one specific embodiment of this utility model, both the output end of the mixer 3 and the delivery pipeline 4 are equipped with flow sensors.

[0049] In specific design, high-precision ultrasonic flow measurement technology can be used for the flow sensor. This technology utilizes the propagation characteristics of ultrasonic waves in cooling and lubricating media to measure flow rate, offering advantages such as non-contact operation, no pressure loss, high measurement accuracy, and strong reliability. High-precision ultrasonic flow measurement technology can improve the accuracy and reliability of flow monitoring, providing crucial information for precise system control.

[0050] In one specific embodiment of this utility model, the conveying fan, air compressor (9), conveying pump (10) and flow sensor are all connected to the same control system.

[0051] In the specific design, the power of the conveying fan, air compressor 9, and conveying pump 10 can be adjusted manually or automatically according to the signal feedback from the flow sensor. More specifically, for the flow sensors located on the conveying pipeline 4, at least one flow sensor is installed upstream and one downstream of the conveying fan.

[0052] In one specific embodiment of this utility model, the integrated device uses an air compressor 9 to generate compressed air. The compressed air is mixed with a lubricating medium to form a suitable cooling and lubricating medium (or cooling and lubricating mixture). The concentrations of compressed air and lubricating medium in the cooling and lubricating medium are controlled according to the equipment's performance. After adjusting the pressure of the air compressor 9, the cooling and lubricating medium is then transported through the conveying pipeline 4 into the medium flow channel 201 (or inner cavity of the vertical rail plate 2) that needs to be cooled. A conveying fan is set up according to the actual conditions of the conveying pipeline 4 (such as differences in pipe material, length, width, and curvature) to counteract pipe resistance and maintain the speed and pressure of the cooling and lubricating medium entering the vertical rail plate 2. The vertical rail plate 2 has a medium flow channel 201 machined inside, and several release holes 202 are distributed on both sides of the vertical rail plate 2. The cooling and lubricating medium enters through these holes into the contact sliding surface between the moving mechanism 101 and the track in the chain clamp assembly 1, generating a lubricating effect. Simultaneously, the compressed air flow carries away the heat generated by friction, completing the lubrication and cooling of the track. The cooling mixture is collected and processed by the recycling and treatment device 8. Specifically, the waste liquid after cooling and lubrication is collected into the collection tray 6 through the recycling hole 5031 set on the track frame 5, and then enters the recycling and treatment device 8 for centralized processing through the recycling pipeline 7. The waste liquid of cooling and lubrication contains a certain amount of gas. The track frame 5 and the collection tray 6 form a relatively sealed space. An induced draft fan is installed in the recycling pipeline 7 to provide negative pressure and improve the collection efficiency of the used cooling and lubrication medium.

[0053] In summary, this utility model can effectively reduce the complexity of equipment and the space occupied, thereby reducing the pressure on factory buildings and public works; it can reduce equipment manufacturing costs, reduce production and operating costs, improve production efficiency, reduce waste discharge pressure, and protect the environment.

[0054] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
