Description

Technical Field

[0001] The present invention relates to the technical field of fiberboard processing, and particularly to a processing device for a non-woven fabric fiberboard soaked with vehicle resin. Background Art

[0002] A non-woven fabric fiberboard is a special type of fiberboard. After impregnating the non-woven fabric with resin, the resin is cured through a hot pressing process to form a board with specific properties. Specifically, when processing a non-woven fabric fiberboard, usually a non-woven fabric of appropriate size is cut out and immersed in a resin solution. Then, the non-woven fabric impregnated with resin is placed in a hot press, and by applying specific pressure and temperature conditions, the resin curing reaction is promoted. During this curing process, the fibers of the non-woven fabric are tightly bonded together, and finally a board with certain strength and specific properties is formed.

[0003] However, in the existing processing process of non-woven fabric fiberboards, the cut non-woven fabric often undergoes no pretreatment before being immersed in resin. Since the non-woven fabric is prone to adsorbing dust and moisture in the air, this directly affects its soaking effect. Moreover, before the non-woven fabric is immersed in resin, the temperature of the non-woven fabric is prone to be uneven, which will cause uneven distribution of the resin on the non-woven fabric, thus easily resulting in defects on the surface of the non-woven fabric fiberboard and reducing the processing quality of the non-woven fabric fiberboard. In addition, after the soaking step is completed, it is necessary to manually take out the non-woven fabric from the resin solution and transfer it to the hot press for hot pressing and curing. Such a manual operation mode is time-consuming and laborious, and it is difficult to achieve assembly line operation, thereby reducing the processing efficiency of the non-woven fabric fiberboard and having poor practicability. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that the processing process of non-woven fabric fiberboards in the prior art lacks pretreatment of non-woven fabrics and is difficult to achieve assembly line operation, thereby reducing the processing quality and processing efficiency of non-woven fabric fiberboards, and to propose a processing device for a non-woven fabric fiberboard soaked with vehicle resin.

[0005] To achieve the above purpose, the present invention adopts the following technical scheme: A processing device for a non-woven fabric fiberboard soaked with vehicle resin, including a frame, a storage tank is installed on the inner wall of the frame, and the storage tank is externally connected with a negative power supply. The device further includes: A winding and vibrating mechanism is arranged on the inner wall of the frame, and a non-woven fabric is arranged on the winding and vibrating mechanism, which is used for step-by-step winding of the non-woven fabric and ultrasonic vibration thereof. A through hole one and a through hole two for the non-woven fabric to pass through are opened at the top of the storage tank, and the width of the through hole two is greater than that of the through hole one; A monitoring and processing mechanism and a preprocessing mechanism, both of which are arranged on the frame. The monitoring and processing mechanism is used to monitor whether the non-woven fabric is damaged and perform repair or cutting operations when damage is detected. The preprocessing mechanism is used to clean, dry, eliminate static electricity, preheat the non-woven fabric before immersion in resin, and perform pre-curing treatment after repair; A resin replenishing mechanism, which is arranged on the frame and the storage tank, and is used to replenish resin into the storage tank and replenish resin to the non-woven fabric that is not fully impregnated; A cutting and curing mechanism and a pushing and conveying mechanism. The cutting and curing mechanism is arranged on the inner wall of the frame, and the pushing and conveying mechanism is arranged on the frame and the cutting and curing mechanism.

[0006] Compared with the existing technology, the advantages of the present invention are as follows: 1. Through the mutual cooperation of the winding vibration mechanism, the preprocessing mechanism and the cutting and curing mechanism, the present invention can not only realize the pipeline processing of the non-woven fabric by transporting, impregnating and cutting and hot-pressing the non-woven fabric, but also use the setting of the cleaning and drying component, the ultrasonic vibration of the first vibration wheel and the second vibration wheel, and the purging of high-energy plasma and hot air to clean, dry, perform ultrasonic vibration, eliminate static electricity and preheat the non-woven fabric before impregnating it, so as to avoid the influence of moisture and dust on its subsequent soaking quality, effectively increase the hydrophilicity and surface binding energy of the non-woven fabric surface, and avoid the deformation problem caused by uneven temperature of the non-woven fabric in the subsequent process. Furthermore, while effectively improving the processing efficiency of the non-woven fabric fiber board, the processing quality of the non-woven fabric is also improved.

[0007] 2. Through the mutual cooperation of the winding vibration mechanism, the monitoring and processing mechanism and the preprocessing mechanism, the present invention can use the ultrasonic vibration of the non-woven fabric to monitor whether the non-woven fabric is damaged, and perform repair or cutting operations according to the size of the damage when damage is detected in the non-woven fabric, and cooperate with the ultrasonic vibration of the non-woven fabric and the preheating of the non-woven fabric to ensure the density and uniformity of the resin filling process, and pre-cure the resin filled at the damaged part of the non-woven fabric, so as to ensure the repair quality of the non-woven fabric, that is, effectively guarantee the processing quality of the non-woven fabric fiber board.

[0008] 3. Through the mutual cooperation of the winding vibration mechanism, the resin replenishing mechanism and the corona mechanism, the present invention can not only use the ultrasonic vibration of the non-woven fabric to ensure the soaking quality of the non-woven fabric and reduce the risk of resin deterioration caused by bubbles, that is, improve the processing quality of the non-woven fabric fiber board and reduce its processing cost, but also use the negative electricity of the resin in the storage tank, the negatively charged atomized resin sprayed by the electric nozzle, the positive electricity of the non-woven fabric and its ultrasonic vibration to effectively ensure the uniformity of the non-woven fabric impregnation while ensuring the complete penetration of the resin into the non-woven fabric, thus further ensuring the processing quality of the non-woven fabric fiber board.

[0009] 4. Through the setting of the capacitance level gauge in the resin replenishing mechanism of the present invention, when the resin level in the storage tank is too low, the spraying amount of the electrostatic nozzle can be increased, and after the resin level in the storage tank returns to normal, it can be adjusted back to the original spraying amount to ensure that there is enough resin in the storage tank for soaking. Moreover, by setting a negative power supply externally connected to the storage tank, when the charged resin sprayed by the electrostatic nozzle falls into the storage tank, it is repelled by the negative charges in the storage tank, thus avoiding the adhesion of resin particles to the inner wall of the tank, which greatly facilitates the subsequent cleaning work. In addition, through the setting of the electric field sensor in the corona mechanism, the electric field intensity on the non-woven fabric can be detected and fed back in real time, and the corona treatment intensity of the corona machine can be flexibly adjusted. In this way, not only can diverse soaking requirements be met, but also the corona treatment process can always be in the best state, thereby ensuring the wide applicability and processing quality of the non-woven fabric processing.

[0010] 5. Through the setting of the cutting and curing mechanism of the present invention, while cutting and thermally pressing the non-woven fabric into shape, the pressing wheels one and two on the male die and the female die can be used to prevent the non-woven fabric from running off or wrinkling, and timely compensate for the possible shrinkage and deformation of the non-woven fabric during the forming process, thus ensuring the forming quality of the non-woven fabric while effectively preventing the non-woven fabric from being torn and damaged due to shrinkage or deformation during the pressing process between the male die and the female die, that is, effectively ensuring the processing quality of the non-woven fabric fiber board.

[0022] When the present invention is in use, first, pass the non-woven fabric 5 between two cleaning and drying components 11, and make its lower surface contact with the first vibration wheel 113 and the upper driving wheel 1. Then, pass it through two first diffusion ports, two ultrasonic identification sensors 13, two spraying manipulators 14, two second diffusion ports, two corona machines 16 and two electric field sensors 17 in sequence, and make its upper surface and lower surface contact with the second vibration wheel 114 and the lower driving wheel 1 respectively. Subsequently, make the non-woven fabric 5 pass through the first through-port and enter the storage tank 18. After passing between two electrostatic nozzles 19, it passes out from the second through-port. At this time, the upper surface of the part of the non-woven fabric 5 located in the storage tank 18 will contact the second vibration wheel 114 and the third vibration wheel 115, and the part of the non-woven fabric 5 passing through the second through-port will be bonded to the winding shaft 119 after passing between the punch 110 and the die 111. After completing the above work, turn on the electrostatic nozzle 19 to atomize the resin configured and stirred evenly in the supply tank 6 and spray it into the storage tank 18 until the liquid level of the resin in the storage tank 18 exceeds the capacitance liquid level gauge 117 for a period of time, then turn off the electrostatic nozzle 19. Since the storage tank 18 is externally connected to a negative power supply, and the resin atomized and sprayed by the electrostatic nozzle 19 is negatively charged (normally, the material sprayed by the electrostatic nozzle 19 is negatively charged), therefore, when the charged resin sprayed by the electrostatic nozzle 19 falls into the storage tank 18, it will be repelled by the negative charges in the storage tank 18, thus avoiding the adhesion of resin particles to the inner wall of the tank and greatly facilitating the subsequent cleaning work.

[0023] After completing the above preparatory work, turn on the motor 118 to drive the winding shaft 119 to rotate and wind the non-woven fabric 5. At this time, the air heater 2, the plasma generator 3, the air pump 4, the cleaning and drying component 11, the ultrasonic identification sensor 13, the corona machine 16, the electric field sensor 17 and the electrostatic nozzle 19 are all in the on state. During the winding process of the non-woven fabric 5, the non-woven fabric 5 will start to move step by step in the whole device, and the non-woven fabric 5 will be ultrasonically vibrated by the first vibration wheel 113, the second vibration wheel 114, the third vibration wheel 115 and the fourth vibration wheel 116. The first vibration wheel 113, the second vibration wheel 114, the third vibration wheel 115 and the fourth vibration wheel 116 have the same structure. Here, the structure of the first vibration wheel 113 is taken as an example for description. While the non-woven fabric 5 moves step by step, connect the external high-frequency power supply into the first vibration wheel 113 through the electrical rotary joint 1131 on the first vibration wheel 113. Under the action of the high-frequency power supply, the piezoelectric ceramic 1132 generates ultrasonic vibration and drives the vibrating piece 1133 to vibrate. The vibrating piece 1133 transmits the vibration to the first vibration wheel 113 and drives the non-woven fabric 5 within the range to perform ultrasonic vibration.

[0024] When the winding shaft 119 starts winding, the non-woven fabric 5 located on the side of the cleaning and drying assembly 11 away from the first vibration wheel 113 will enter between the two cleaning and drying assemblies 11. Subsequently, by controlling the cleaning and drying assembly 11, the non-woven fabric 5 is cleaned and dried to ensure that the non-woven fabric 5 in the subsequent process is clean and dry enough. Then the non-woven fabric 5 will reach the first diffusion port. At this time, the high-energy plasma continuously generated by the plasma generator 3 will be sent to the first diffusion port through the purge pipe 12 and purge the surface of the non-woven fabric 5, thereby eliminating the static electricity on the surface of the non-woven fabric 5 and preventing the non-woven fabric 5 from adsorbing dust and affecting its subsequent soaking quality. At the same time, under the purge of the high-energy plasma, the hydrophilicity of the surface of the non-woven fabric 5 can be increased, thereby improving the impregnation of the resin in the subsequent impregnation process of the non-woven fabric 5 and the bonding strength between the resin and the non-woven fabric 5, that is, improving the subsequent soaking quality of the non-woven fabric 5.

[0025] Since the first vibration wheel 113 and the second vibration wheel 114 can drive the non-woven fabric 5 to perform ultrasonic vibration, and when the non-woven fabric 5 performs ultrasonic vibration, it will generate ultrasonic waves. On the one hand, these ultrasonic waves will cause micron-level pits and nano-level protrusions on the surface of the non-woven fabric 5 fibers during the propagation process, thereby increasing the specific surface area of the non-woven fabric 5 and further improving its hydrophilicity. On the other hand, the ultrasonic recognition sensor 13 can real-time monitor the ultrasonic signals emitted by the non-woven fabric 5 and feed these signals back to the control assembly. The control assembly then analyzes these signals to identify whether the non-woven fabric 5 passing through the ultrasonic recognition sensor 13 is damaged. When a damage signal is detected, if the analyzed damage is greater than 5 mm, it is determined that the damage is too large, and an alarm is immediately issued to prompt the staff to come and deal with it. Subsequently, the staff will cut and remove the entire non-woven fabric 5 in the area where the damaged position is located and recycle it, and use a suitable connection process to rejoin the non-woven fabric 5 to ensure the continuity of the non-woven fabric 5 processing process and the processing quality of the non-woven fabric 5.

[0026] If the damage is less than 5 mm, the movement of the non-woven fabric 5 is stopped and the position signal is fed back to the spraying manipulator 14, so that it moves to the damaged position through the adjustment assembly. Subsequently, the vision device on the spraying manipulator 14 will take a photo of the damaged part for review (the vision device on the spraying manipulator 14 is a prior art and will not be elaborated here) to confirm the damage situation, and after confirmation, the damaged part of the non-woven fabric 5 will be filled with resin by spraying. At this time, the surface of the highly hydrophilic non-woven fabric 5 will quickly absorb the resin sprayed by the spraying manipulator 14, and under the ultrasonic vibration of the non-woven fabric 5, the gas infiltrating into its interior will be quickly discharged, effectively avoiding the generation of bubbles, thereby ensuring the compactness and uniformity of the resin filling process, that is, ensuring the repair quality of the non-woven fabric 5. After the damaged area of the non-woven fabric 5 is fully filled with resin and reaches the predetermined standard, the spraying manipulator 14 will immediately stop the spraying operation. At this time, the motor 118 is continued to be turned on and the non-woven fabric 5 is made to perform step-by-step movement.

[0027] The air heater 2 and the air extraction pump 4 are respectively connected to two diffusion ports II through two preheating pipes 15. In this configuration, the air heater 2 operates continuously to heat the air to about 80°C. When the air extraction pump 4 is started, a strong suction force will be generated. Through the conduction of the preheating pipe 15, a negative pressure is formed at the diffusion port II corresponding to the air extraction pump 4, thereby generating a suction effect on the other diffusion port II. This suction force extracts the heated air in the air heater 2 and continuously and evenly blows it to the surface of the non-woven fabric 5 through the preheating pipe 15 and the diffusion port II, so as to perform heat treatment (i.e., preheating) on the non-woven fabric 5, effectively avoiding the deformation problem caused by uneven temperature in the subsequent process, and further improving the surface binding energy of the non-woven fabric 5, making its binding with the resin tighter and stronger, thereby further improving the subsequent soaking quality. During this process, the resin filled in the damaged part of the non-woven fabric 5 begins to pre-cure, further ensuring the repair quality of the non-woven fabric 5.

[0028] Subsequently, the non-woven fabric 5 will move between two corona machines 16 and undergo corona treatment. During the corona treatment process, a uniform plasma layer will be formed on the surface of the non-woven fabric 5. This plasma layer can effectively improve the surface tension and adhesion of the non-woven fabric 5, thereby enhancing its subsequent soaking quality. At the same time, by controlling the corona machine 16, positive charges are evenly distributed on the surface of the non-woven fabric 5, and the electric field intensity on the non-woven fabric 5 is detected and fed back in real time through the electric field sensor 17. The staff uses the electric field intensity as an index to evaluate the charge quantity, and flexibly adjusts the corona treatment intensity of the corona machine 16 according to different soaking requirements. In this way, not only can diverse soaking requirements be met, but also the corona treatment process can always be in the best state, thereby ensuring that the corona treatment effect of the non-woven fabric 5 reaches the optimal level.

[0029] The non-woven fabric 5 that has completed the above-mentioned pre-treatment will enter the storage tank 18 and be horizontally immersed in the resin under the guidance of the vibrating wheel three 115 and the vibrating wheel four 116. At this time, the positively charged non-woven fabric 5 will quickly absorb the negatively charged resin until the electric charges are neutralized and the attractive force disappears. At this time, the adhesion of the resin to the non-woven fabric 5 will be greatly reduced. Although under the influence of factors such as van der Waals force and resin viscosity, a corresponding amount of resin on the outermost side of the non-woven fabric 5 will still continue to adhere to its surface, the adhesion of these resins is extremely low and is easily shaken off under the ultrasonic vibration of the vibrating wheel three 115 and the vibrating wheel four 116. Even if it is not shaken off, the negatively charged resin attached at this time can prevent the excessive adhesion of the subsequent negatively charged resin under the action of the repulsive force, thus ensuring that the non-woven fabric 5 can be evenly impregnated with the resin. In addition, under the ultrasonic vibration of the vibrating wheel three 115 and the vibrating wheel four 116, it can not only effectively promote the exhaust of the non-woven fabric 5 during the immersion process and quickly eliminate the possible bubbles, but also avoid the bubbles generated in the resin due to the introduction of the non-woven fabric 5. This dual effect not only ensures the immersion quality of the non-woven fabric 5 but also reduces the risk of resin deterioration caused by bubbles, thereby improving the processing quality of the non-woven fiberboard while reducing the processing cost.

[0030] Subsequently, the non-woven fabric 5 will move to the electrostatic spray head 19. If the non-woven fabric 5 has been completely impregnated with the resin, the negatively charged atomized resin sprayed by the electrostatic spray head 19 at this time will be continuously shaken off by the non-woven fabric 5 under the ultrasonic vibration of the vibrating wheel three 115 and the vibrating wheel four 116 (referring to the non-woven fabric 5 without the resin with extremely low adhesion mentioned above), or be repelled by the negatively charged resin adhered to the non-woven fabric 5 (referring to the non-woven fabric 5 with the resin with extremely low adhesion mentioned above), thus avoiding the excessive adhesion of the resin. If the non-woven fabric 5 is not completely impregnated due to reasons such as time and impurities, the negatively charged atomized resin sprayed by the electrostatic spray head 19 will adsorb and supplement the parts of the non-woven fabric 5 that are not completely impregnated (at this time, the parts of the non-woven fabric 5 that are not completely impregnated will still carry some positive charges), and continuously shake off the resin with low adhesion on the outermost side under the ultrasonic vibration of the vibrating wheel three 115 and the vibrating wheel four 116 to ensure the uniformity of the impregnation of the non-woven fabric 5. During the operation of the entire device, the capacitance level gauge 117 continuously monitors the liquid level of the resin in the storage tank 18. When the liquid level is too low, the spraying amount of the electrostatic spray head 19 is increased until the liquid level exceeds the capacitance level gauge 117 for a period of time, and then the spraying amount is adjusted back to ensure that there is enough resin in the storage tank 18 for immersion.

[0031] The impregnated non-woven fabric 5 will pass through the second through-hole and move between the male mold 110 and the female mold 111. At this time, the male mold 110 is moved towards the female mold 111 by controlling the first oil cylinder 1103. During the movement, the required non-woven fabric 5 is cut off by the cutter 1106 thereon (at this time, the cutter 1106 is located in the cutter groove 1119 on the female mold 111, and the non-woven fabric 5 stops moving). The cut non-woven fabric 5 is pressed tightly by the first pressing wheel 1105 and the second pressing wheel 1118 arranged around the male mold 110 and the female mold 111 to prevent the non-woven fabric from running off or wrinkling, thus effectively ensuring the curing quality of the non-woven fabric 5. Subsequently, by turning on the coil assembly 1111, a magnetic field and heat are generated by electrification to heat the female mold 111. Finally, the male mold 110 and the female mold 111 thermally press and form the impregnated non-woven fabric 5. During the entire forming process, the first pressing wheel 1105 and the second pressing wheel 1118 will flexibly follow the rolling of the non-woven fabric 5 to timely compensate for the possible inward shrinkage and deformation of the non-woven fabric 5 during the forming process, thereby ensuring the forming quality of the non-woven fabric 5 while effectively preventing the non-woven fabric 5 from being torn and damaged due to inward shrinkage or deformation during the pressing process between the male mold 110 and the female mold 111.

[0032] After completing the above work, cold water is provided for the cooling pipes in the male mold 110 and the female mold 111 through the water pipes externally connected to the first water joint 1104 and the second water joint 1114, thereby realizing the cooling of the non-woven fabric 5 on the male mold 110 and the female mold 111 after thermal pressing and curing, that is, realizing the cooling of the non-woven fabric fiber board. After a period of time, the first oil cylinder 1103 is controlled to quickly reset the male mold 110, and the second oil cylinder 1116 is controlled to make the push plate 1113 advance, so that the push rod 1117 on the push plate 1113 is inserted into the through-hole, and the non-woven fabric fiber board is pushed onto the guide plate 112 and finally slides onto the conveying assembly 7 and is conveyed to the subsequent process for post-treatment.

[0033] After that, the non-woven fabric 5 resumes moving. The cutting of the non-woven fabric 5 mentioned above is not a full-width cutting, but only the middle part of the non-woven fabric 5 is cut. Therefore, it will not affect the winding of the winding shaft 119, that is, it will not affect the subsequent movement of the non-woven fabric 5. In addition, the non-woven fabric 5 that has not undergone the complete processing process (that is, the non-woven fabric 5 in the whole device during the preparation work) will be directly wound by the winding shaft 119 and will not go through the cutting and thermoforming processes of the male mold 110 and the female mold 111. Since the non-woven fabric 5 has good solubility and recyclability, the non-woven fabric 5 wound by the winding shaft 119 can also be reconnected into the non-woven fabric 5 after appropriate treatment to carry out the above processing process, thus realizing the effective utilization and recycling of resources.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
