Description

Technical Field

Biaxially oriented plastic film (BOPF) is a general term for plastic films made by biaxial stretching (or biaxial orientation). Most of the films produced by biaxial stretching equipment are used in packaging, electrical materials, photosensitive materials, agriculture, architectural decoration and daily necessities. Biaxially oriented film has developed rapidly in the past decade and has become the main packaging material for various high-performance packaging films. As the market demand for stretch film increases, more and more biaxial stretching equipment is put into use.

[0028] (4) Reduce waste discharge pressure The reduction of friction can further reduce the use and emission of lubricants, and reduce the waste and pollutant emissions generated during the production, use and recycling of lubricants. This has positive significance for environmental protection, helps companies reduce investment and pressure in environmental protection, and meets the requirements of sustainable development. At the same time, reduced equipment wear means that waste parts and other waste generated by equipment maintenance and replacement are also reduced accordingly, further reducing the burden on companies in waste disposal.

[0029] (5) Facilitate equipment modification and upgrading The technical solution of the present invention can be implemented by transformation on existing equipment.

DETAILED DESCRIPTION

[0032] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. Each example is provided by way of explanation of the present application and does not limit the present application. In fact, it will be clear to those skilled in the art that modifications and variations may be made in the present application without departing from the scope or spirit of the present application. For example, a feature shown or described as a part of an embodiment may be used in another embodiment to produce yet another embodiment. Therefore, it is desired that the present application includes such modifications and variations within the scope of the appended claims and their equivalents.

[0033] In the description of this application, the terms "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and do not require that this application must be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application. The terms "connected", "connected", and "set" used in this application should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0034] like Figures 1 to 8 As shown, a device for reducing the running friction of a chain clip assembly comprises a track frame 2 connected to the chain clip assembly 1, the chain clip assembly 1 comprises a moving member 101, a supporting member 102 and a clamping mechanism 103 connected in sequence, and the track frame 2 comprises an upper frame 201, a vertical frame 202 and a lower frame 203 connected in sequence; The upper end of the lower frame 203 is connected to a bottom support rail 3, which supports the bottom side of the support member 102 and is slidably connected to the bottom side of the support member 102; The moving member 101 includes a ferromagnetic material component, and the upper frame 201 is provided with a magnet 4 . The magnet 4 can attract the ferromagnetic material component to reduce the pressure generated by the chain clip assembly 1 on the bottom support rail 3 .

[0035] In the prior art, the bottom support rail 3 bears the main vertical force generated during the movement of the chain clip assembly 1, so the friction between the bottom side of the support member 102 and the bottom support rail 3 is very large. By arranging a magnet 4 on the upper frame 201 to reduce the pressure generated by the chain clip assembly 1 on the bottom support rail 3, the friction between the bottom side of the support member 102 and the bottom support rail 3 can be effectively reduced.

[0036] like Figure 4 As shown, N represents the supporting force of the bottom rail 3 on the chain clip assembly 1, N = the pressure Fn generated by the chain clip assembly 1 on the bottom rail 3; G represents the gravity of the chain clip assembly 1, and F represents the attraction of the magnet 4 to the ferromagnetic material component. In an ideal situation (considering only the main force), when the magnet 4 is not set, Fn1=N1=G, and the friction force f1=μ×Fn1=μ×G between the bottom rail 3 and the bottom side of the support member 102; when the magnet 4 is set, Fn2=N2=GF, and the friction force f2=μ×Fn2=μ×(GF) between the bottom rail 3 and the bottom side of the support member 102. When the gravity G is constant, as F increases, the friction force f2 decreases accordingly, which can meet the requirements of reducing the friction of the chain clip assembly, thereby achieving a series of reductions in operating costs, lubricant usage, emissions, etc.

[0037] During specific production, the main components of the moving part 101 can all be made of ferromagnetic materials (materials whose main components include metals such as iron, nickel, and cobalt), that is, the ferromagnetic material components can be any components of the moving part 101, such as the frame, bearings, axle pins, and chain links.

[0038] During the film stretching process, the combined forces of the chain clip assembly's own gravity, the film tension component, and high-speed impact increase the friction of the chain clip assembly. The device of the present invention can effectively reduce the friction between the chain clip and the running track, reduce production and operation costs, improve equipment operation efficiency, improve production benefits, and reduce waste discharge pressure. Compared with the prior art, the present invention directly reduces the pressure of the chain clip assembly on the bottom support rail by arranging a magnet on the upper frame to attract the ferromagnetic material components of the chain clip assembly, thereby effectively reducing the friction between the chain clip assembly and the track. This innovative design can effectively solve the problems of high energy consumption and large lubricant consumption of double-pull equipment without changing the main structure of the existing equipment. It can be applied to the manufacture of new equipment and the transformation of old equipment (it only needs to open a hole in the upper frame of the existing equipment and implant a magnet).

[0039] In a specific embodiment of the present invention, the magnets 4 are arranged on the track frame assembly 5 at intervals along the running direction.

[0040] The running sections of the track frame group 5 include a preheating section 501, a stretching section 502, and a shaping section 503, etc., which may be further subdivided according to the specific process. When making specific arrangements, the areas with greater friction during the operation of the stretching production line can be determined based on the measurement of the equipment operation status (the present invention provides a measurement method: infrared imaging is performed when the equipment is running, and the infrared imaging shows that the areas with higher temperatures usually have greater friction) or by querying the previous operation / damage / repair records of the equipment. The magnets can be densely arranged in the areas with greater friction, and the magnets can be dispersedly arranged in the areas with less friction.

[0041] The magnets can be flexibly arranged according to the actual situation of the track frame group running section, which can reduce the friction in a targeted manner. This method can avoid the problem of waste of resources or insufficient friction reduction in key areas caused by the uniform arrangement of magnets, improve the technical effect of reducing friction, and optimize the operating performance of the equipment.

[0042] In a specific embodiment of the present invention, the magnet 4 is a ferrite magnet, the width of the magnet 4 is 20-80 mm, the length is 20-80 mm, the thickness is 15-40 mm, and the magnet 4 is arranged at intervals of 400-1200 mm along the running section of the track frame assembly 5.

[0043] The magnets 4 are arranged at intervals of 400 to 1200 mm, that is, the distance between the center point of the previous magnet 4 and the center point of the next magnet 4 adjacent to the running section along the track frame assembly 5 is 400 to 1200 mm, preferably 600 to 1000 mm.

[0044] Considering the difficulty of modifying the current existing equipment models, the magnet 4 in the present invention is preferably a permanent magnet. Ferrite magnets are cheap and their performance can meet the requirements of the present invention. In addition to ferrite magnets, other permanent magnets such as neodymium iron boron magnets and aluminum nickel cobalt magnets with better performance can also be selected. With the different magnet materials selected, the specifications and setting spacing of the magnets can be adjusted according to the actual production conditions.

[0045] In a specific embodiment of the present invention, the magnets 4 are arranged continuously on the track frame assembly 5 along the running direction.

[0046] The method of continuously arranging magnets can continuously reduce friction in a wider area, which helps to further improve the overall operating efficiency and stability of the equipment. However, the difficulty and capital investment of continuously arranging magnets for the modification of existing equipment models are greater than that of interval arrangement. If permanent magnets are arranged continuously, the specifications and quantity of the magnets 4 need to be adjusted according to the different stages of the production line. In this regard, a modular installation structure can be designed to integrate the magnets and their attached fixing devices, adjustment devices, etc. into an independent module, which is convenient for rapid installation and replacement on existing equipment and reduces the difficulty of modification. For example, using a plug-in / adsorption connection module, the magnet module can be increased, decreased or replaced through simple operations.

[0047] If the modification of the current existing equipment model is not considered, but a film stretching production line is redesigned, the magnet 4 can also be an electromagnet. The electromagnet can change the magnetic force by increasing or decreasing the current, so that the magnetic force of the electromagnet can be adjusted in time according to the different specifications of the stretch film, the different production process parameters, and the different operating conditions of the production line to obtain the most suitable working state.

[0048] In a specific embodiment of the present invention, the left end and / or the right end of the upper frame 201 is connected to the vertical rail plate 6, and the support member 102 is provided with a U-shaped groove opening upward, and the vertical rail plate 6 is embedded in the U-shaped groove.

[0049] In specific design, the inner side of the U-shaped groove of the support member 102 can be provided with a wear-resistant non-metallic sliding block, or a wear-resistant coating can be applied.

[0050] The vertical rail plate 6 is embedded in the U-shaped groove of the support member 102 to provide precise guidance for the chain clip assembly 1 to move in a specific direction. In film stretching production, the chain clip assembly needs to operate stably and accurately to ensure uniform film stretching, high dimensional accuracy and stable quality. This structure limits the lateral displacement of the chain clip assembly and reduces operating deviation and vibration. For example, in the production of high-precision electronic product packaging films, it reduces defects such as uneven film thickness and tensile strength fluctuations caused by unstable operation, thereby improving the yield rate and product performance.

[0051] In a specific embodiment of the present invention, the moving member 101 includes metal links, and the plurality of chain clip assemblies 1 are connected by the metal links.

[0052] In film stretching production, the chain clip assembly needs to withstand continuous tension, friction and impact. The high strength and high toughness of the metal chain link can firmly maintain the connection of the assembly, prevent loosening and breaking, and ensure stable operation of the equipment. In addition, the metal chain link can also be attracted by the magnet 4 to reduce the pressure of the connection assembly 1 on the bottom rail 3.

[0053] In a specific embodiment of the present invention, the clamping mechanism 103 includes a film clamp 1031 and a clamping mechanism frame 1032 , and the clamping mechanism frame 1032 is connected to the support member 102 .

[0054] The film clamp 1031 cooperates with the clamping mechanism frame 1032 and the latter is connected to the support member 102, which can ensure accurate and stable clamping of the film, maintain accurate film positioning throughout the stretching process, ensure uniform stretching in all directions, and greatly improve the quality of the film. The film clamp 1031 and the clamping mechanism frame 1032 can be integrated or made into a detachable connection component that can be quickly disassembled and replaced.

[0055] In a specific embodiment of the present invention, the magnet 4 is embedded in the upper frame 201 .

[0056] like Figure 5 As shown, there are many options for the magnet's appearance, including block type and strip type. In order to facilitate installation and positioning, steps / protrusions can also be set on the magnet. This embedding method helps to protect the magnet 4 and ensure that it is stably fixed on the upper frame 201.

[0057] The method of embedding the magnet 4 inside the upper frame 201 not only makes the device structure more compact and beautiful, but also effectively protects the magnet 4 from the influence of the external environment, and improves its service life and stability. Compared with the exposed installation method, this design can effectively reduce the interference of factors such as collision and dust on the performance of the magnet, and ensure the durability of the friction reduction effect.

[0058] In a specific embodiment of the present invention, the middle part of the upper frame 201 is connected to the middle part of the lower frame 203 through the vertical frame 202, magnets 4 are provided on the left and right sides of the upper frame 201, the left and right ends of the upper frame 201 are connected to the vertical rail plates 6, and the upper ends of the left and right sides of the lower frame 203 are connected to the bottom support rails 3.

[0059] This design allows the left and right sides of the track frame 2 to be connected to the chain clip assembly 1 in the stretching direction and the retracting direction respectively. The symmetrical track frame structure design provided in this embodiment can meet the operation requirements of the chain clip assembly in both the stretching and retracting directions, and can improve the versatility and production efficiency of the equipment. By reasonably configuring the magnets, vertical rail plates and bottom support rails, effective support, guidance and friction reduction of the bidirectional chain clip assembly can be achieved.

[0060] In a specific embodiment of the present invention, the magnet 4 is a ferrite magnet, the width of the magnet 4 is 20-80 mm, the length is 20-80 mm, the thickness is 15-40 mm, and the edge distance between the adjacent magnets 4 on the left and right sides of the upper frame 201 is 50-90 mm.

[0061] The parameters given in this embodiment are not set arbitrarily, but are the optimization results obtained through a large number of experiments, simulations and theoretical calculations. By precisely controlling the size and spacing of the magnets, a specific magnetic field distribution can be formed during the operation of the chain clip assembly, so that the magnetic field can achieve the best attraction to the ferromagnetic material components below it, which can effectively streamline the overall layout of the stretching equipment and will not cause adverse interference to the chain clip assembly in the opposite direction (stretching direction / retraction direction), thereby most effectively reducing the pressure of the chain clip assembly on the bottom rail and reducing friction. The appropriate size of the magnet can ensure that while providing sufficient attraction, it will not cause additional burden or interference to other parts of the equipment (such as the track frame, chain clip assembly, etc.) due to its own excessive weight or excessive magnetic field.

[0062] More specifically, due to the chain clip assembly in the stretching direction, the component force of the clamping mechanism clamping the film also needs to be considered. Therefore, for the magnet arrangement in the stretching direction, the number density of the magnets arranged on the upper rack can be relatively large or magnets with relatively large specifications can be selected; for the magnet arrangement in the recovery direction, the number density of the magnets arranged on the upper rack can be relatively small or magnets with relatively small specifications can be selected.

[0063] In order to further reduce the negative impact caused by the friction between the chain clip assembly 1 and the track, the present invention strengthens the lubrication and cooling of the relative movement between the chain clip assembly 1 and the track.

[0064] In a specific embodiment of the present invention, the device for reducing the running friction of the chain clip assembly also includes a mixer 701, the input end of the mixer 701 inputs compressed air and lubricating medium, the output end of the mixer 701 outputs cooling lubricating medium, a medium flow channel 601 is provided inside the vertical rail plate 6 and / or inside the bottom support rail 3, the side wall of the vertical rail plate 6 is provided with a release hole 602 that penetrates the medium flow channel 601, and the output end of the mixer 701 is connected to the medium flow channel 601 through a conveying pipeline 702.

[0065] The cooling lubricating medium is a mixture of compressed air and a lubricating medium. Commonly used lubricating media include lubricating oil, grease, solid powder, etc. Preferably, the lubricating medium in the present invention is lubricating oil. By mixing compressed air with the lubricating medium, it can be ensured that the lubricating medium is quickly released from the release hole 602 and adheres to the surface of the lubricated part to be cooled to achieve lubrication. The introduction of compressed air can quickly take away the heat generated by the high-speed operation of the chain clip assembly 1 on the track by convection heat transfer. In addition, since the vertical rail plate 6 in the present invention is embedded in the inner side of the support member 102 (U-shaped groove), the rapid injection of compressed air can temporarily establish a layer of air diaphragm between the inner side of the support member 102 and the vertical rail plate 6 and inject sufficient lubricating medium, which can effectively reduce the contact strength between the support member 102 and the vertical rail plate 6, and can effectively reduce the friction between the support member 102 and the vertical rail plate 6.

[0066] Compressed air not only takes away the heat generated by friction, but also helps to dissipate the heat of the magnet. During operation, the magnet will generate a certain amount of heat due to changes in the magnetic field and other reasons. If the heat cannot be dissipated in time, it may cause the magnetic properties to decline, affecting its attraction to the chain clip assembly. The cooling effect of compressed air can keep the magnet in a low temperature state and maintain its stable magnetic field strength, thereby continuously and effectively reducing the pressure of the chain clip assembly on the bottom rail. The stable magnetic field is conducive to the smooth operation of the chain clip assembly, reducing the generation of additional friction caused by factors such as vibration, and further promoting the effect of reducing friction in the entire system.

[0067] The lubricating medium forms a uniform lubricating film between the chain clip assembly and the track, making the movement of the chain clip assembly smoother. This not only directly reduces the friction, but also allows the chain clip assembly to run more accurately along the track under the action of the magnetic attraction. Without good lubrication, the chain clip assembly may not be able to move completely in the direction and force of the magnetic attraction due to surface roughness or local jamming, resulting in limited actual friction reduction effect. The presence of the lubricating medium eliminates these unfavorable factors, allowing the magnetic attraction to play a better role. The two complement each other and jointly improve the efficiency and stability of the chain clip assembly operation, further enhancing the overall friction reduction effect.

[0068] The rapid gas / liquid flow generated by the compressed air entraining the lubricating medium can effectively remove dust, impurities, etc. attached to the surface of the chain clip assembly 1 or the track (vertical track plate 6, etc.). These impurities may enter the gap between the chain clip assembly and the track, increase friction, and may even damage the components. When the impurities are removed, the contact between the chain clip assembly and the track is purer, which is conducive to the magnetic field generated by the magnet to act more effectively on the ferromagnetic material components, reducing the problem of reduced attraction caused by impurities blocking or interfering with the magnetic field. At the same time, the clean surface can also make the lubricating medium adhere and function better, further improving the overall performance of the entire system to reduce friction.

[0069] Therefore, the combination of the cooling and lubricating medium technical solution and the magnet technical solution can promote and synergize each other through various mechanisms, achieving a more significant effect of reducing the operating friction of the chain clip assembly than using either solution alone, which is of great significance in improving equipment performance, reducing energy consumption and extending equipment service life.

[0070] The mixer 701 in the prior art only needs to merge the pipelines of compressed air and lubricating medium to meet the output of cooling lubricating medium. An improved solution for the mixer 701 is given below: The mixer with adaptive adjustment is equipped with intelligent sensors and microprocessors. The intelligent sensor can monitor the pressure, temperature, humidity of compressed air and the viscosity and flow rate of lubricating medium in real time. The microprocessor automatically adjusts the mixing ratio of compressed air and lubricating medium by adjusting the pipe diameter or opening and closing of multiple input pipes according to the preset algorithm and real-time monitoring data to meet the cooling and lubrication requirements under different working conditions. For example, under high temperature and high load conditions, the proportion of lubricating medium is increased to enhance the lubrication effect, and the compressed air pressure is appropriately increased to improve the cooling efficiency; under low temperature and low load conditions, the proportion of lubricating medium is reduced accordingly to avoid waste and pollution caused by excessive lubrication. The mixer with adaptive adjustment can accurately control the composition of cooling and lubricating medium according to the actual working conditions, improve the accuracy of cooling and lubrication effects, extend the service life of key components of equipment, reduce equipment failures caused by insufficient or excessive lubrication, untimely cooling, etc., thereby improving production efficiency and reducing maintenance costs.

[0071] In a specific embodiment of the present invention, for the vertical rail plate 6, the medium flow channel 601 includes at least one horizontal medium flow channel 6011 and multiple vertical medium flow channels 6012, the release hole 602 is connected to the vertical medium flow channel 6012, and the conveying pipeline 702 is connected to the horizontal medium flow channel 6011.

[0072] There are many design schemes for the specific shape of the medium flow channel 601. The present invention provides a technical scheme with low processing difficulty. In addition to the "one horizontal and multiple vertical" mentioned in the above scheme, it can also be "multiple horizontal and one vertical" (in this case, the release hole 602 is connected with the horizontal medium flow channel 6011, and the conveying pipeline 702 is connected with the vertical medium flow channel 6012), "multiple horizontal and multiple vertical" (in this case, the release hole 602 is connected with the horizontal medium flow channel 6011 and / or the vertical medium flow channel 6012, and the conveying pipeline 702 is connected with the horizontal medium flow channel 6011 and / or the vertical medium flow channel 6012).

[0073] By processing a transverse medium flow channel 6011 and a vertical medium flow channel 6012 inside the vertical rail plate 6, a plurality of release holes 602 (or oil seepage holes, oil injection holes) are distributed on the left side and / or right side of the vertical rail plate 6. The cooling lubricating medium enters the contact sliding surface between the support member 102 and the track through the release holes 602 to produce a lubricating effect. At the same time, the rapid flow of compressed air takes away the heat generated by friction.

[0074] In specific design, according to the different lengths of the vertical rail plate 6, a plurality of connection interfaces between the delivery pipeline 702 and the transverse medium flow channel 6011 can be provided, and arranged at appropriate intervals.

[0075] In a specific embodiment of the present invention, the lower frame 203 is provided with a recovery hole 2031 , and a collection tray 703 is provided below the recovery hole 2031 .

[0076] The waste liquid and waste gas after cooling and lubrication are collected in the collection tray 703 through the recovery hole 2031 for recovery.

[0077] In a specific embodiment of the present invention, a sealed chamber 1 801 is formed between the chain clip assembly 1 and the upper frame 201, the vertical frame 202, the lower frame 203 and the bottom support rail 3, the collection plate 703 wraps the lower frame 203, and a sealed chamber 2 802 is formed between the collection plate 703 and the lower frame 203, and the sealed chamber 1 801 and the sealed chamber 2 802 are connected through the recovery hole 2031.

[0078] In this embodiment, the parts to be cooled and lubricated include the support member 102, the vertical rail plate 6 (outer side), the bottom support rail 3, etc. In the specific design, the collection tray 703 is provided with a slope biased to one side, which is conducive to the flow of waste liquid. Since there will be a small gap between adjacent chain clip assemblies 1, and there will also be a small gap in the connection between the chain clip assembly 1 and the track frame 2, the sealed chamber 1 801 is not an absolutely sealed state in the strict sense but a relatively sealed state. However, the relative sealing state of the sealed chamber 1 801 can effectively reduce the compressed air and lubricating medium in the cooling lubricating medium from overflowing from the chain clip assembly 1. Due to the existence of the recovery hole 2031 and the sealed chamber 2 802, the waste liquid and compressed air in the sealed chamber 1 801 can be smoothly discharged to the collection tray 703.

[0079] The design of sealed chamber 1 and sealed chamber 2 not only helps to recover the cooling lubricant, but also has a certain positive impact on the magnetic field and lubrication effect. The sealed chamber can reduce the impact of external factors (such as airflow interference, dust intrusion, etc.) on the internal magnetic field and lubrication environment. The stable magnetic field environment can ensure that the magnet continues to stably attract the chain clip assembly, while the stable lubrication environment can make the lubricant work better. This comprehensive stable environment is conducive to the synergy of the two technical solutions, making the friction reduction effect more lasting and reliable.

[0080] In a specific embodiment of the present invention, the collection tray 703 is connected to the recovery processing device 705 through the recovery pipeline 704.

[0081] The cooling lubricating medium that has completed the lubrication and cooling functions passes through the collection tray 703 and the recovery pipeline 704 in turn and enters the recovery and processing device 705 for collection and processing. In the specific design, the recovery and processing device 705 can realize gas-liquid separation, and there will be a small amount of lubricating medium in the recovered gas. Therefore, from the perspective of resource conservation, the recovered gas can be reused to prepare compressed air, and the recovered liquid can be reused to prepare lubricating medium.

[0082] In a specific embodiment of the present invention, the recovery pipeline 704 is provided with an induced draft fan.

[0083] Since the track frame 2 and the collection plate 703 form a relatively sealed space - the sealed chamber 2 802, for the gas in the cooling lubricating medium, by setting an induced draft fan in the recovery pipeline 704, a negative pressure can be formed between the sealed chamber 2 802 and the recovery pipeline 704, thereby improving the collection efficiency of the used cooling lubricating medium.

[0084] In a specific embodiment of the present invention, the delivery pipeline 702 is provided with a delivery fan.

[0085] During the conveying process, the necessary conveying fans are set according to the pipeline layout to maintain the speed and pressure of the cooling and lubricating medium when it enters the vertical rail plate 6.

[0086] In a specific embodiment of the present invention, compressed air is generated by an air compressor 706 and delivered to the mixer 701 , and the lubricating medium is delivered to the mixer 701 by a delivery pump 707 .

[0087] In the prior art, compressed air can be prepared by using a dedicated air compressor or by using factory-shared compressed air. In this embodiment, in order to further facilitate regulation, a dedicated air compressor 706 is used to produce compressed air, and the pressure of the compressed air produced by the air compressor 706 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 lubricating medium, which is then transported into the medium flow channel 601 of the vertical rail plate 6 by a delivery pipeline 702. The cooling lubricating medium produced in the mixer 701 is a mixture of compressed air and a lubricating medium, wherein the concentration of the lubricating medium can be regulated by a delivery pump 707 according to the actual use effect of the equipment or the feedback of the monitoring signal.

[0088] In a specific embodiment of the present invention, flow sensors are provided at the output end of the mixer 701 and the delivery pipeline 702 .

[0089] In the specific design, the flow sensor can adopt high-precision ultrasonic flow measurement technology. This technology uses the propagation characteristics of ultrasonic waves in the cooling and lubricating medium to measure the flow rate, and has the advantages of non-contact, no pressure loss, high measurement accuracy, and strong reliability. High-precision ultrasonic flow measurement technology can improve the accuracy and reliability of flow monitoring and provide an important basis for the precise control of the system.

[0090] In a specific embodiment of the present invention, the delivery fan, the air compressor 706, the delivery pump 707 and the flow sensor are all connected to the same control system.

[0091] In specific design, the power of the conveying fan, air compressor 706, and conveying pump 707 can be adjusted manually or automatically according to program settings based on the signal feedback of the flow sensor. More specifically, the flow sensor located on the conveying pipeline 702 is provided at least one flow sensor upstream and one flow sensor downstream of the conveying fan.

[0092] In summary, the present invention can effectively reduce the operating friction of the chain clip assembly, reduce production and operation costs, improve production efficiency, and reduce waste discharge pressure.

For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
