Description

Technical Field

[0001] The present invention belongs to the technical field of high-end equipment, and in particular relates to an air knife system and a plush surface treatment blowing and brushing combined machine with the air knife system. Background Art

[0002] In recent years, textiles have undergone major changes from raw materials to finishing processes, especially conventional specifications of textiles are facing increasingly fierce competition, which has affected the healthy development of enterprises and industries. The country's requirements for clean energy-saving production and intelligent manufacturing are getting higher and higher. Most of the equipment in production is based on operating experience and has extremely high requirements for labor, which has restricted the healthy development of enterprises. Refined production process control and less-manpowered intelligent digital production are imperative.

[0003] For the post-finishing industry, especially the animal-like plush plates with special treatment on the hair surface, processes such as blowing, brushing, and hot polishing are required. There are many production equipment and long process lines, which also brings troubles to process control and digital production. Now there is an urgent need for a multifunctional, efficient, stable and high-precision automated equipment.

[0004] For the existing blow molding process equipment, all of them have independent blow molding functions. After blowing, the plush is cooled and piled, and then brushed at room temperature. Before piling, the plush cloth must be cooled to below 50°C, otherwise it will cause pile marks. This cooling process requires a lot of power energy. Because the plush fiber has good shape retention characteristics at room temperature, it needs to be brushed many times to be smooth. There are many processing equipment, and there are batch quality differences between multiple production lines. This is also an existing dilemma that needs to be solved urgently.

[0005] In the prior art, the hot air temperature control in the blowing process generally adopts a proportional valve to control the air-fuel ratio to burn heat energy. The temperature of the hot air is displayed rather than linked, which often causes the working hot air temperature to get out of control, reducing the final finishing effect and even requiring rework.

[0006] The working hot air is controlled by the wind knife to control the flow and direction. The size, angle, position, outlet temperature and uniformity of the wind knife are key process indicators. Hot air is normally heated by built-in combustion of gas. During the heating process, foreign matter such as waste wool fibers will be entrained in the fuel, especially the combustion-supporting air. When burned, large hard particles will be formed, which can easily cause blockage of the wind knife mouth. The existing technology requires regular removal of the wind knife air outlet side panels for cleaning, which is time-consuming and troublesome, and there is also the possibility of damage to the wind knife during operation. Due to the structure of the wind knife, there are generally multiple air inlets on the side of the vertical air outlet of the blade body along the length of the wind knife, which is a non-continuous surface air inlet method. This also causes deviations in pressure, flow, temperature and other aspects of the hot air entering the inner cavity of the wind knife, which can easily cause large deformation of the wind knife when working, and style deviations in the plush surface after finishing.

[0007] The temperature control of the existing hot air heating process is achieved by directly controlling the flow of heating gas and combustion-supporting air through proportional valves. However, different plush has different requirements for finishing temperature and air pressure. When adjusting these parameters, the temperature of the working hot air is often affected, resulting in changes in the blowing effect, which ultimately affects the quality of the finished product.

[0008] During the weaving process, due to the space size limitation of the equipment, the grey cloth generally has a specific length. In the subsequent dry and wet finishing process, it is stitched and spliced ​​as needed to form a longer size and realize continuous production. Since the grey cloth is woven to a fixed length and then stitched, a large number of seams (seam heads) are generated. In the post-finishing process, especially the dry finishing process, the finishing device needs to disengage and avoid when encountering seam heads. The existing technology generally adopts photoelectric detection or gravity micro-motion stroke amplification. It is very easy to cause signal errors due to factors such as on-site dust, electromagnetic environment, and mechanical vibration, resulting in malfunctions or even production accidents. Therefore, the automatic seam head avoidance function of the existing technology is still insufficient and cannot be stably promoted. The seam head avoidance is still manually operated, which also creates a huge obstacle to the realization of intelligent production in the future. It is a problem that must be overcome at this stage.

[0009] After the plush is blown, the surface fibers curl and clump together, so they need to be brushed open and straightened. The current technology uses a multi-pass brushing and combing method at room temperature to ensure brushing and fiber shape retention, which results in a long production line. With more brushing and combing times, the entire plush surface gradually becomes softer, and the cloth is more likely to curl when entering and exiting the machine, which has affected normal production. Summary of the invention

[0010] In view of the shortcomings of the prior art, the present invention provides an intelligent search technology that effectively utilizes the high weather resistance and anti-interference characteristics of lasers to achieve accurate and long-term stability of non-contact measurement. The comprehensive application of photoelectric signal transmission technology solves the adverse effects of the transmission process and distance, especially under the working conditions of high ambient temperature of hot air forming equipment, the signal stability and transmission accuracy of seam head detection are doubled. The technical solutions adopted are as follows:

[0011] A wind knife system includes a wind knife and an air intake system. The air intake system includes a fan, an air intake duct and an air outlet duct. In order to achieve the purpose of uniform air supply, the air outlet duct is connected to an air distributor. The air distributor is connected to the wind knife through a plurality of air distribution ducts to form uniform air supply. The number of air distribution ducts is adjusted according to actual conditions. The number of air distribution ducts can be 1, 2, 3...N.

[0012] Preferably: in order to achieve hot air heating, a combustion and control mechanism is also provided, and the combustion and control mechanism includes a feeding system, an ignition chamber and an ignition nozzle. Since the above mechanism belongs to the prior art, the applicant will not repeat it here. The air inlet duct is connected to the ignition chamber, and the ignition chamber is provided with an ignition nozzle. The ignition chamber is connected to the air distributor through a pipeline, and the feeding system can select different types of fuels according to actual needs.

[0013] Preferably: in order to achieve the purpose of uniform air supply, the wind knife includes a wind knife body, the wind knife body is provided with a plurality of air inlets, at least two layers of equalizing plates are provided from bottom to top in the wind knife body, and the upper surface area of ​​the equalizing plates is getting smaller and smaller, and a plurality of air inlets are provided on the equalizing plates, and the air inlets of the adjacent two layers of equalizing plates are perpendicular to each other. Such a design can evenly divide the wind in the wind knife, thereby achieving the purpose of uniform air outlet. The present invention successfully applies the combined multi-layer gap equalizing technology, and through the setting of multiple layers of mutually perpendicular ventilation gaps, the hot air passing through the gaps of each layer of cloud pressure plates is evenly heated and evenly flowed, so that the temperature of the hot air entering the inner cavity of the wind knife from multiple air inlets is more consistent, which greatly reduces the thermal deformation of the wind knife caused by uneven heating of the blade body. By setting a detachable filter at multiple air inlets, the combustion particles entrained in the hot air are filtered out to avoid entering the knife cavity and blocking the wind knife air outlet.

[0014] Preferably: in order to ensure long-term safe operation of the equipment, the air inlet is connected to a filtering device.

[0015] Preferably: in order to better control the operation of the equipment, it also includes a wind knife spacing adjustment mechanism, which includes a drive motor, a wind knife connecting shaft, a wind knife limit frame, an adjustment screw rod, a lifting reducer seat, a lifting reducer, an upper fixed plate and a lifting synchronization rod, the lifting synchronization rod is movably installed between the lifting reducer, the drive motor is connected to the lifting reducer, the lifting reducer is installed on the lifting reducer seat, the lifting reducer seat is connected to the wind knife limit frame, the lower part of the adjustment screw rod is connected to the connecting piece, the connecting piece is connected to the wind knife connecting shaft, the connecting piece is respectively provided with a locking device and a wind knife angle adjuster, and the wind knife connecting shaft is connected to the wind knife fixed side plate.

[0016] Preferably: in order to achieve the purpose of uniform air supply, three layers of equalizing plates are provided in the wind knife body from bottom to top, namely, equalizing plate one, equalizing plate two and equalizing plate three. The number of equalizing plates can be adjusted accordingly according to needs, which can be 1, 2, 3, ...N.

[0017] A plush surface treatment blowing and brushing combined machine includes a frame part, a cloth spreading mechanism, a cloth tightening mechanism, a deviation correction and centering mechanism, a cloth outlet cooling mechanism, a cloth outlet manipulation mechanism, a combustion and control mechanism, an air knife spacing adjustment mechanism, a brush assembly, a traction mechanism, a floating hair cleaning mechanism, an electrical control system and an arc roller flattening mechanism, and also includes the above-mentioned air knife system.

[0018] Preferably: in order to solve the seam problem, a seam detection mechanism is also provided, which includes a bearing seat, a support shaft and a detection roller. The two ends of the support shaft of the seam detection device are respectively concentrically mounted with bearing seats and fixed to the wall panels on both sides by bolts. The two connecting plates are perforated with one end coaxially mounted on the tube body of the support shaft, and a square support block is installed on the inner side of the middle. The two ends are respectively mounted on the connecting plates by bolts, and are positioned by set screws after aligning the position. Self-aligning bearings are respectively installed in the holes at both ends of the detection roller, and are positioned by hole permanent retaining rings. One end of the detection roller core shaft is concentrically mounted on the inner hole of the self-aligning bearing, and the other end is fixed to the connection plate by bolts. One end of the detection connecting plate is mounted on the support shaft near the wall panel, and is positioned by set screws, and is reduced in weight and shock by tension springs to adapt to the detection of seams of different fabrics. One end of the detection stop iron frame is fixed to the detection connecting plate by bolts, and the other end is installed with a detection stop iron, forming a rigid body that can rotate as a whole according to the bearing seat. The detector is fixed to the detector support by screws, and the detector cover fixed to the detector support by screws is used for light shielding protection. Because the emitter and receiver of the laser detector are on the same side of the same instrument, a certain band of natural light in the working environment is isolated, which can significantly increase the instrument's resistance to ambient light interference. The laser beam's strong resistance to electromagnetic interference, strong penetration, and high feedback accuracy are effectively utilized, which improves the reliability of the seam detection system while also improving the accuracy by orders of magnitude. The detection stop iron adopts a multi-joint locking fixation method, which can facilitate multi-dimensional adjustment of spatial position angles.

[0019] Preferably: in order to achieve long-term safe operation of the system, the bristle assembly includes a bristle roller, a bristle suction hood, an air collecting pipe, a suction hose, a spacing lifting motor and a brush roller motor. The air collecting pipe and the main suction hose are connected, and the suction hose is connected to the bristle suction hood.

[0020] The present invention has the following advantages:

[0021] The present invention adopts a modular structure with functions, realizes multiple finishing functions at the same workstation, reasonably utilizes the residual heat of blowing for hot brushing and combing, and utilizes the curled and clumped fibers in a soft state to make it easier to brush and smooth. In the dust removal and air suction process, the finished plush is further cooled, which saves energy while increasing the finishing effect and reducing the production space.

[0022] The effective application of involute variable laminar flow suction and dust removal technology optimizes the use of fluid kinematics technology based on the airflow movement characteristics generated by the rotating working state of the equipment components and the movement characteristics of the entrained waste. With lower suction energy consumption, it simultaneously realizes the suction of the waste fluff after brushing in the brushing area and the rapid cooling of the fluff after brushing, further reducing energy consumption.

[0023] The automatic temperature control technology integrates the multi-parameter signal joint control and correction intelligent control technology, which solves the problem of working hot air temperature drift easily caused by changing process parameters such as working air pressure in existing technical equipment, and the temperature control accuracy is improved exponentially.

[0024] The short-process finishing technology integrates the technology to solve the impact of changes in the performance characteristics of the fabric during the finishing process on the subsequent processes, and the production capacity and quality are improved simultaneously.

[0025] Laser ranging technology is used to accurately measure the thickness of the plush fabric to be sorted. When the instantaneous thickness change caused by the seam hole is detected, the signal of the point where it is located is sent back to the PLC, and the encoder is triggered to measure the position at the same time. The PLC compares the position change with the stored seam avoidance action data in real time, and automatically performs pneumatic deflection seam avoidance and automatic return when the seam reaches the wind knife and brush roller. The laser ranging technology used in the present invention effectively avoids the influence of harmful environmental factors such as dust, electromagnetic and mechanical vibration, and achieves a qualitative improvement in accuracy, anti-interference and stability.

[0026] Since the working hot air adopts the internal direct combustion mixed heating method, there is a laminar interlayer with a higher temperature, which is harmful to the finishing of the fleece surface. By using the combined multi-layer gap uniform flow technology, the hot air passing through is screened and then merged through the gap plate made of high heat transfer material. The multi-layer vertical ventilation gap setting further evenly mixes the hot air, making the temperature of the hot air entering the air knife cavity from multiple air inlets more consistent, greatly reducing the thermal deformation of the air knife caused by uneven heating of the knife body. By setting detachable filters at multiple air inlets, the combustion particles entrained in the hot air are filtered and removed regularly to avoid entering the knife cavity and blocking the air outlet of the air knife.

[0027] It adopts an integrated involute cavity suction hood structure and suctions air on both sides, making full use of the circular involute thrust generated by the high-speed rotation of the brush roller and the side-rotating centrifugal force of the brush bristle tip that separates the waste fluff from the brush, thereby slowing down the waste fluff and gathering it in a specific area, further improving the dust removal effect and achieving energy-saving dust removal.

[0028] By adopting online signal detection of multiple working parameters and real-time data collection and comparison and matching operation by PLC, mutual control and complementarity after changes of various working parameters are realized, the problem of easy temperature drift of hot air during the working process is solved, the consistency of wool surface finishing is further improved, and the high-end transformation of the finished plush is realized.

[0029] The combined blowing and brushing finishing at the same station is adopted. In the brushing process, the heat energy left on the wool surface in the blowing process is fully utilized, and combined with the softening characteristics of the plush fiber at a certain temperature, hot brushing without an additional heat source is realized. In order to further reduce the deformation of the plush grey cloth during the brushing process and ensure the combing effect, a rapid cooling structure is provided on the back of the plush before the hot brush to cool the plush base cloth, improve the elasticity and toughness of the base cloth, and thus effectively reduce the deformation of the plush grey cloth during the brushing process and effectively reduce the hair loss during the brushing process. It not only utilizes the fact that the plush fiber is relatively soft and easy to comb and shape at a certain temperature, but also utilizes the three-dimensional air cooling of the hair roots of the brushed fibers during the brushing suction process, and the comprehensive benefits are significant.

[0030] By adopting a solution that efficiently integrates the blowing and combing processes, and arranging and combining the blowing and brushing processes as needed, the obvious effect of complementary and efficient utilization of various finishing methods is achieved, which saves a lot of production resources while improving efficiency.

[0031] The present invention adopts the use of hot air inlet filtering device to prevent large hard particles from entering the inner cavity of the wind knife, and then staying and blocking the wind knife edge, causing the appearance of sorting waste, and also greatly reduces the difficulty of wind knife maintenance work and damage during the maintenance process. According to the formation mechanism of working hot air and the mutual control and complementarity of influencing factors, the digital conversion and real-time matching of working parameters are realized, and the digital precise control of the production process is realized, creating an excellent platform for intelligent digital production.

[0032] Various safety technologies and online sensor detection ensure the long-term high stability and high safety of the entire equipment, minimizing production downtime and the occurrence of production accidents. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Embodiment 1

[0045] like Figure 1-Figure 10 As shown:

[0046] The present invention relates to a plush surface treatment blowing and brushing combined machine. Through the combined structure and the physical characteristics of the fabric to be treated in the process stage, the kinematics and fluid mechanics technology are used to set the functional working area and specific structure of the whole machine according to the production requirements of the process, and the multifunctional equipment is created through simulation verification. The algorithm is further optimized, the application database is improved, and the specific mechanism is matched to improve the level of intelligent and safe and efficient production, providing equipment support for further realizing regional intelligent production. The overall structure is composed of different functional modules.

[0047] like Figure 1 , Figure 2 As shown, the whole equipment has two key functional areas, blowing and combing, and multiple subsidiary mechanisms. The key blowing mechanism can be composed of two or more sets of air knife components, which can be arranged continuously or spaced apart from the combing mechanism. The combing mechanism can have two or more sets, and can be arranged continuously or spaced apart from the blowing mechanism, so as to fully utilize energy and improve quality and efficiency.

[0048] like Figure 3 , Figure 4As shown, the two ends of the support shaft 12-2 of the seam detection device are respectively concentrically installed with bearing seats 12-1, and are fixed to the wall panels on both sides by bolts. The two connecting plates 12-3 are perforated and one end is coaxially mounted on the tube body of the support shaft 12-2. A square support 12-4 is installed on the inner side of the middle. The two ends are respectively installed on the connecting plate 12-3 by bolts, and are positioned by set screws after finding the correct position. Self-aligning bearings 12-6 are respectively installed in the holes at both ends of the detection roller 12-5, and the hole retaining ring 12-7 is used to position the hole. One end of the detection roller core shaft 12-8 is concentrically installed in the inner hole of the self-aligning bearing 12-6, and the other end is fixed to the connecting plate 12-3 by bolts. One end of the detection connecting plate 12-9 is mounted on the support shaft near the wall panel, and is positioned by a set screw, and is reduced in weight and shock by a tension spring 12-15 to adapt to the detection of seams of different types of fabrics. One end of the detection stop iron frame 12-10 is fixed to the detection connecting plate 12-9 by bolts, and the other end is installed with the detection stop iron 12-14, forming a rigid body that can rotate as a whole according to the bearing seat 12-1.

[0049] The detector 12-13 is fixed to the detector support 12-12 by screws, and the detector cover 12-11 fixed to the detector support 12-12 by screws is used for light shielding protection. Because the emitter and receiver of the laser detector are on the same side of the same instrument, a certain band of natural light in the working environment is isolated, which can significantly increase the instrument's resistance to ambient light interference. The laser beam's strong resistance to electromagnetic interference, strong penetration, and high feedback accuracy are effectively utilized, which improves the reliability of the seam detection system while also improving the accuracy by orders of magnitude. The detection stop 12-10 adopts a multi-joint locking fixation method, which can facilitate multi-dimensional adjustment of the spatial position angle.

[0050] Existing seam detection technologies mostly use capacitor and inductor instruments, which need to be compared after the displacement value calculation and conversion, that is, real-time detection and comparison calculation are required. To detect the change in the value of the electrical signal caused by the position change, in most cases, the change value of the electrical signal caused by the position change is close to the signal change caused by environmental factors. The only way to amplify and collect the signal is to use signal means. However, the signal fluctuation caused by mechanical micro-vibration cannot be removed. Therefore, the existing technology can only be used in occasions where the partial change amount is sufficient to cover the error caused by environmental conditions. The laser ranging technology of the present invention adopts a control method of signal on (off) after the detection distance limit exceeds the limit, which directly shields the signal fluctuation within the range. The limit position value is directly called by the PLC according to the fabric characteristic parameter value or coding input into the production system. The equipment database data is an intelligent process for automatic matching of process working parameters, which is safe and reliable. In addition, by adding a shock-absorbing damping spring to the detection mechanism, the influence of the deadweight of the detection mechanism on the detection process and signal is effectively reduced, and the vibration of the detection roller during the seam head process is reduced, further ensuring the accuracy of the detection signal.

[0051] like Figure 8 As shown, the wind knife spacing adjustment mechanism 8 includes a driving motor 8-8, a wind knife connecting shaft 8-9, a wind knife limiting frame 8-12, an adjusting screw rod 8-13, a lifting reducer seat 8-14, a lifting reducer 8-15, an upper fixed plate 8-16 and a lifting synchronization rod 8-17, the lifting synchronization rod 8-17 is movably installed between the lifting reducer 8-15, the driving motor 8-8 is connected to the lifting reducer 8-16, the lifting reducer 8-16 is installed on the lifting reducer seat 8-14, the lifting reducer seat 8-14 is connected to the wind knife limiting frame 8-12, the lower part of the adjusting screw rod 8-13 is connected to the connecting piece, the connecting piece is connected to the wind knife connecting shaft 8-9, the connecting piece is respectively provided with a locking device 8-11 and a wind knife angle adjuster 8-10, the wind knife connecting shaft 8-9 is connected to the wind knife fixed side plate 8-1;

[0052] like Figure 6 , Figure 7 As shown:

[0053] A wind knife system includes a wind knife 8 and an air inlet system 7-2, the air inlet system 7-2 includes a fan, an air inlet duct and an air outlet duct, the air outlet duct is connected to an air distributor 7-5, the air distributor 7-5 is connected to the wind knife 8 through a plurality of air distribution ducts 7-6 to form a uniform air supply, and is also provided with a combustion and control mechanism 7, the combustion and control mechanism 7 includes a feeding system 7-1, an ignition chamber 7-3 and an ignition nozzle 7-4, the air inlet duct is connected to the ignition chamber 7-3, the ignition chamber 7-3 is provided with an ignition nozzle 7-4, and the ignition chamber is connected to the air distributor 7-5 through a duct.

[0054] The wind knife includes a wind knife body 8-1, which is provided with a plurality of air inlets. At least two layers of equalizing plates are provided inside the wind knife body from bottom to top, and the upper surface area of ​​the equalizing plates is getting smaller and smaller. The equalizing plates are respectively provided with a plurality of air inlets, and the air inlets of two adjacent layers of equalizing plates are perpendicular to each other.

[0055] Since the wind knife body 8-1 needs to be deflected at an angle during the working process, a wind knife angle adjuster 8-10 with an angle scale is fixed on the wind knife connecting shaft 8-9, and a locking device 8-11 is installed on the seam head cylinder joint 08-05 to quickly lock the wind knife connecting shaft 8-9 after the rotation adjustment to achieve the angular adjustment of the wind knife body 8-1.

[0056] For the hot air blowing surface finishing of plush, the key is the uniformity of the hot air, including the accuracy of temperature, wind pressure and wind knife action angle. Due to the existing wind knife structure, the air inlet is discontinuous, but the air outlet must be continuous and the wind pressure is uniform. The hot air heating method is to use gas direct combustion and direct mixing. During the combustion process, high-temperature and high-speed airflow is generated, which is very easy to produce vortex high-temperature laminar gas interlayer. The high-temperature impact of the interlayer airflow is large, which is easy to cause damage to the hair surface and abnormal deformation of the wind knife body. The current wind knife generally has a short service life, which is the main reason.

[0057] Multi-layer slit perforated plates are used to efficiently extrude and divide the hot air passing through, and the position and orientation of the slits in each layer are different, which increases the screening and remixing effect of the hot air flowing through, realizes multiple mixing of cold and hot layered hot air, and assimilates and flattens the local high temperature and high speed value of the hot air.

[0058] like Figure 5 As shown:

[0059] The combustion control system is mainly composed of a gas control subsystem, a compressed air combustion-supporting wind control subsystem, a PLC central control subsystem and a hot air heating and conveying subsystem.

[0060] The combustion control subsystem is composed of an air intake joint, a gas pressure regulating valve, an electromagnetic stop valve, and an air intake elbow, which are sealed and connected in sequence to form an inlet gas pressure control component. Then the component is sealed and connected to the filter chamber joint and the filter chamber to form a working gas inlet main pipeline. A plurality of gas branch pipelines composed of a gas ball valve, a low-pressure switch, and an electromagnetic stop valve are arranged on the gas filter chamber, and are transported to the Venturi mixer on the combustion chamber through a gas bellows. The electromagnetic stop valves of the branch pipelines are controlled by the ignition controller controlled by the PLC via the low-pressure switch. The low-pressure switch controls the gas circuit to cut off for protection when the system is short of gas. A working gas pressure display pipeline is arranged on the gas filter chamber, which is sealed and connected in sequence by a gas ball valve and a high-pressure switch, and is connected to the gas pressure gauge through a gas bellows. The high-pressure switch controls the air intake electromagnetic stop valve, and when the pressure of the gas supplied is abnormal, it is controlled and cut off to prevent the abnormal pressure gas from entering and diverting.

[0061] The compressed air combustion-supporting wind subsystem is a processing and control system for the combustion-supporting compressed air. After being processed by the two-piece gas processing unit, the compressed air is transported to the manual pressure regulating valve through a hose for pressure regulation, and then transported to the proportional valve controlled by the PLC through a hose for autonomous flow control, and then delivered to the Venturi mixer on the combustion chamber to form the combustion-supporting compressed air subsystem.

[0062] The logic control subsystem is mainly composed of the main logic controller PLC communication connected to the human-machine interface touch screen for human-machine data exchange and autonomous measurement and control, and signal detectors such as wind pressure transmitters and temperature meters for online real-time data collection, and transmitted to the PLC through a dedicated controller or module conversion, and after processing, the combustion control subsystem and the compressed air combustion wind subsystem are controlled by the ignition controller. The opening of the proportional valve is calculated by the PLC autonomous program through the acquisition of temperature controller signals and working wind pressure signals, and complementary joint control is performed, realizing the full integration of working parameters and process parameters, accurate and agile response, and high safety.

[0063] The working hot air heating control process is that the gas and combustion-supporting compressed air transmitted by the gas control subsystem and the compressed air combustion-supporting subsystem enter the Venturi mixer through pipelines for premixing respectively, and the flow rate is controlled by the PLC through signal comparison and compensation logic collected by each measurement and control instrument. For example, when the pressure of the working air is adjusted due to different processing requirements, the minimum opening of the proportional valve controlled by the PLC changes proportionally to the wind pressure, which solves the problem of the lack of linkage with the change in the amount of gas inflow caused by the pressure change in the combustion chamber, and has a high degree of automation and safety.

[0064] like Fig. 9 , Fig.10 As shown:

[0065] The bristle assembly 9 includes a bristle roller 9-5, a bristle suction hood 9-2, an air collecting pipe 9-3, an air suction hose 9-4, a spacing lifting motor 9-5 and a brush roller motor 9-6. The air collecting pipe 9-3 and the main air suction hose 9-4 are connected, and the air suction hose 9-4 is connected to the bristle suction hood 9-2.

[0066] The passive end of the brush roller 9-5 is installed into the inner hole of the brush roller bearing seat through the concentrically set self-aligning bearing, and is sealed with a bearing seat cover and a skeleton oil seal. The active end of the brush roller 9-5 is installed into the inner hole of the brush roller bearing seat through the concentrically set self-aligning bearing, and is sealed with a bearing seat cover and a skeleton oil seal. The two brush roller bearing seats are fastened to the wall panel by bolts to complete the positioning and installation of the brush roller assembly. The head of the active end of the brush roller 9-5 is concentrically connected to the fixed brush roller pulley by an expansion sleeve, and the power is input through the transmission V-belt for rotation. The brush roller motor 9-6 is installed on the outside of the wall panel through the brush roller motor seat, and a brush roller motor pulley is concentrically installed on the shaft head of the brush roller motor 9-6 as a power input source.

[0067] The two sides of the brush suction hood 9-2 of the suction dust removal assembly are connected and fixed to the inner side of the two wall panels through the air collecting pipe bracket. The center of the inner cavity cross section of the suction hood 9-2 is set to a certain eccentricity with the center of the brush roller 9-1, and each end face is provided with two air outlets to facilitate the suction of waste fluff generated during the brushing process. The lower end of the air collecting hood 9-3, which is bolted and fixed to the two rear columns, is provided with two air outlets, which are connected to the side air outlet of the suction hood 9-2 through the suction hose 9-5 to form a suction flow channel. The offset setting of the suction hood cavity and the rational use of the vortex laminar flow generated by the rotation of the brush roller increase the dust suction effect of the system and reduce the energy consumption of dust removal.

[0068] The outer groove of the gauge slider is fixed on the gauge rail slideway on the inner side of the wall panel through two side mountings to form a sliding pair that can slide up and down. The end face of the gauge slider is connected to the base of the elevator joint. The gauge lifting motor 9-5 is connected and fixed to the outer side of the wall panel through the gauge motor seat.
