Description

Technical Field

[0001] The invention relates to the field of wastewater treatment of composite material hot pressing equipment, and in particular to a hot pressing equipment that utilizes clean wastewater for optimized cooling. Background Art

[0002] Hot pressing is a commonly used processing technology, which is usually used to combine two or more thin sheets of different materials by high temperature and high pressure to produce a composite material with specific properties. It can achieve the complementary advantages of different materials, thereby obtaining a composite material with superior performance. In the process of hot pressing and compounding, the materials to be compounded are first placed together, and then high temperature and high pressure are applied to cause diffusion, dissolution or chemical reaction between the materials, thereby forming a strong bond at the interface. In the hot pressing process, when the hot press combines a variety of thin sheet profiles by hot pressing, the various thin sheet profiles are generally coated with adhesive. In the hot pressing, there is excessive adhesive coating or excessive hot pressing extrusion, which causes the adhesive to overflow and remain on the pressing roller. When the residual adhesive overflows on the pressing roller, there is residual glue and the residual glue is easy to absorb dust to form impurities, so that particles are protruding on the surface of the pressing roller, affecting the subsequent hot pressing effect. Therefore, it is necessary to clean the pressing roller to remove the residual glue on the pressing roller and the impurities generated by the residual glue. The patent application number CN201320728629.9 discloses a fluoroplastic composite device, which directly uses a cooling roller to omit the pressing roller during the hot pressing process, and does not produce particulate matter on the pressing roller due to residual glue that affects production problems. However, when the cooling roller and the hot roller are directly used for hot pressing control, there is a temperature difference between the temperature of the cooling roller near the hot roller and the temperature of the end away from the hot roller. When the cooling roller rotates and reaches the hot pressing position, the temperature of the cooling roller may not reach the cooling temperature. Summary of the invention

[0030] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0031] Embodiment 1

[0032] like Figures 1 to 8As shown, a hot pressing device using clean wastewater for optimized cooling comprises a discharge component (wherein the discharge component is a plate discharge platform 1 or a plastic discharge device 11), a preheating oven 2, a hot pressing component and a receiving component 7. The device is turned on in the hot pressing working state. After the preheating oven 2 and the electromagnetic heating roller 3 in the hot pressing component reach the softening temperature of the plastic plate, the raw materials to be compounded are placed on the plate discharge platform 1 or the plastic discharge device 11. The compounded raw materials are transported to the preheating oven 2 through a conveying device by the discharge component for preheating. The discharge mechanism of the hot pressing component comprises a plastic film discharge component 4 for placing plastic film and a glass fiber cloth discharge component 5 for placing glass fiber cloth. The plastic film on the plastic film discharge component 4 is discharged through a first conveying component 12. The material is delivered to the electromagnetic heating roller 3, wherein the first conveying assembly 12 is composed of a plurality of transmission rollers, and the glass fiber cloth mounted on the glass fiber cloth discharge assembly 5 is discharged to the electromagnetic heating roller 3 through the second conveying assembly 13, wherein the second conveying assembly 13 is composed of a plurality of transmission rollers, and the plastic film and the glass fiber cloth intersect, and at the same time, the base material in the discharge component is preheated by the preheating oven 2 and then enters through the base material inlet of the hot pressing component, and after the base material meets the multi-layer raw material, it is sent into the gap between the electromagnetic heating roller 3 and the pressing roller 9 through the transport roller 40, and then the electromagnetic heating roller 3 and the pressing roller 9 are controlled to perform hot pressing on the three raw materials, and the hot-pressed composite board is introduced into the cooling roller 10 for cooling, and after cooling, it is cut by the flying knife 6 and introduced into the receiving component 7 for receiving the material, thereby completing the composite process.

[0033] The hot pressing component includes a discharge mechanism, an electromagnetic heating roller 3, a pressure roller 9, and a cooling roller 10, which are arranged in sequence from top to bottom. The hot pressing component also includes a cleaning arm 15 with a cleaning nozzle 14 and a cleaning scraper 16, wherein the cleaning nozzle 14 is connected to the water storage tank 20 through a water pipe and a water pump (not shown in the attached figure). The water pump extracts the clean water stored in the water storage tank 20 and sends it to the cleaning nozzle 14 for cleaning. The water storage tank 20 stores the clean water added from the outside and the clean water obtained after filtering through the filter box 42. The pressure roller 9 is cleaned by the cooperation of the cleaning nozzle 14 and the cleaning scraper 16. When in use, the operator controls the cleaning arm 15 to move and adjust the cleaning nozzle 14 to flush and clean the place where the pressure roller 9 needs to be cleaned, and the flushed sewage drips into the guide groove 33 below. An adjusting groove 17 is provided on the shell 29 of the hot pressing component corresponding to the cleaning arm 15, and a hand control handle 18 of the cleaning arm 15 passes through the adjusting groove 17 and extends out of the box body. During production, the operator can use the hand control handle 18 to slide in the adjusting groove 17 to manually control the cleaning nozzle 14 to clean the pressing roller when cleaning is needed. The cleaning arm 15 can be controlled by the operator to make reciprocating movements in the left and right directions in the inner cavity of the hot pressing component to clean the stains on the pressing roller. The cleaning nozzle 14 passes through the adjusting groove 17 and is aimed at the pressing roller 9. The cleaning scraper 16 is connected to one end of a guide pipe 19 for receiving waste water and waste materials. The other end of the guide pipe 19 is connected to a water storage tank 20 through a filter assembly. The water storage tank 20 is connected to the cooling member 2 through a water pipe and a water pump (not shown in the attached drawings). 1, the cooling member 21 includes an arc-shaped fitting concave surface 22 adapted to the cooling roller 10, the arc-shaped fitting concave surface 22 fits with the low temperature zone B of the cooling roller 10, the cooling roller 10 is cooled when it fits with the composite product to be cooled during operation, and the heat on the composite product quickly raises the temperature of this part of the cooling roller 10, the entire cooling roller 10 has a high temperature zone A and a low temperature zone B during operation, the high temperature zone A is the area fitting with the composite material after hot pressing, and the low temperature zone B is the area not fitting with the composite material after hot pressing, the cooling member 21 is connected to the cleaning nozzle 14 through a water pipe and a water pump (not shown in the attached drawings), the water pump extracts the cooling member 21 into the cleaning nozzle 14, and then the cleaning nozzle 14 cleans the pressing roller 9. By designing a cleaning nozzle 14 and a cleaning scraper 16 in the hot pressing component to clean the pressing roller 9 after the hot pressing operation, the residual glue and impurities on the pressing roller 9 are removed, and the generated waste water is filtered. In subsequent operations, the cooling roller 10 can be auxiliary cooled, so that the cooling roller 10 can smoothly reach the cooling temperature during operation, effectively and efficiently cool the composite material after hot pressing, and ensure production quality.

[0034] The cleaning arm 15 includes a straight rod 23 connected to the hand-controlled handle 18 and a movable rod 24 connected to the cleaning nozzle 14. One end of the movable rod 24 is axially connected to the straight rod 23, and the other end of the movable rod 24 is connected to the cleaning nozzle 14. A rotating rod 25 for controlling the rotation of the movable rod 24 around the axial connection is provided in the inner cavity of the hot pressing component corresponding to the movable rod 24. A sliding groove 26 is provided in the rotating rod 25, and the movable rod 24 can move left and right in the sliding groove 26. The two ends of the rotating rod 25 are respectively connected to the synchronous gear 27 connected to the side wall. Specifically, the two end ends of the rotating rod 25 are respectively connected to the web of the synchronous gear 27 on the same side, and the synchronous gear 27 is connected to the adjustment rod 28 extending out of the hot pressing component. When in use, the operator rotates the adjustment rod 28 connected to the synchronous gear 27 up and down, and the rotation of the adjustment rod 28 drives the synchronous gear 27 to rotate around the installation axis, drives the rotating rod 25 to make a circular motion, and at the same time the movable rod 24 follows the circular motion. The operator adjusts the appropriate angle according to the stubborn stains seen in the transparent window 30, controls the cleaning nozzle 14 to perform high-pressure water cleaning on the pressure roller 9, and the residual glue and impurities washed down fall into the guide groove 33 in the main body 31. It should be noted that by adjusting the connection friction between the synchronous gear 27 and the side wall, the friction between the synchronous gear 27 and the side wall is greater than the sum of the deadweight of the cleaning arm 15 equipped with the cleaning nozzle 14 and the vibration force during water spray cleaning, so that after the adjustment rod 28 is rotated to the appropriate position, there will be no obvious displacement between the synchronous gear 27 and the side wall.

[0035] The housing 29 is provided with a transparent window 30 on one side close to the cleaning arm 15. The pressure roller 9 is connected to the lifting cylinder through a mounting bracket. The transparent window 30 is designed on the housing 29, and the operator can observe through the transparent window 30, and more intuitively judge whether the pressure roller 9 needs to be cleaned, so as to perform the cleaning operation in time. At the same time, due to the existence of the transparent window 30, when the operator observes that a large amount of residual glue is squeezed out and remains on the pressure roller 9, this abnormal situation may be caused by the gap between the pressure roller 9 and the electromagnetic heating roller 3 being too small. The height of the pressure roller 9 can be adjusted by controlling the lifting cylinder, and the gap between the pressure roller 9 and the electromagnetic heating roller 3 can be increased to ensure the normal operation of the hot pressing work.

[0036] The filter assembly includes a filter box 42 and an outlet pipe 43. The guide pipe 19 is connected to the filter box 42. The filter box 42 includes a filter layer obliquely arranged in the inner cavity. The filter box is separated into a circulation collection part 44 and a water collection part 45 by a filter plate 34. The circulation collection part 44 is used to receive the wastewater introduced from the guide pipe 19. The wastewater flows into the water collection part 45 after being filtered by the filter layer. The filtered water in the water collection part 45 is connected to the water storage tank 20 through the outlet pipe 43 and a water pump (the water pump is not drawn in the figure). Solid impurities are collected by the circulation collection part 44 and discharged from the hot pressing equipment. Impurities containing colloids can be used for coating on the raw material film for reuse after subsequent separation.

[0037] The cleaning scraper 16 includes a main body 31 and a scraper 32. The scraper 32 is tilted on one side of the main body 31. A guide groove 33 is recessed inwardly at the connection between the main body 31 and the scraper 32. The closer the guide groove 33 is to the connection with the guide pipe 19, the deeper the groove is. After the cleaning nozzle 14 sprays cleaning to the pressure roller 9, the cleaned waste water flows from the scraper 32 into the guide groove 33, and is sent to the filter box 42 for filtration through the inclined guide groove 33 into the connecting pipe 41. The residual glue and residual impurities after filtration are collected in the circulation collection part 44, and can be taken out regularly in the later stage. After treatment, they can be reused. The filtered clean water is sent to the cooling member 21 through the outlet pipe 43. The cooling roller 10 is cooled when it is in contact with the composite product that needs to be cooled during operation. At the same time, the heat on the composite product quickly increases the temperature of this part of the cooling roller 10. The entire cooling roller 10 has a high temperature zone A and a low temperature zone B during operation. Since the cooling roller 10 is rolling all the time, when it passes through the low temperature zone B from the high temperature zone A to the high temperature zone A again, there may be untimely cooling of the roller body. Therefore, the cooling member 21 is arranged in the low temperature zone B to be in contact with the cooling roller 10 to perform exogenous auxiliary cooling on the cooling roller 10, so that the cooling roller 10 can be effectively cooled.

[0038] The cleaning scraper 16 includes a main body 31 and a scraper 32. The scraper 32 is tilted on one side of the main body 31. A guide groove 33 is recessed inwardly at the connection between the main body 31 and the scraper 32. The closer the guide groove is to the connection with the guide pipe 19, the deeper the groove is.

[0039] The filter layer includes, from top to bottom, a filter plate 34 with filter holes, a PP cotton filter layer 35, and a granular activated carbon filter layer 36. The filter plate 34 is used to isolate and filter large solid impurities; the PP cotton filter layer 35 is used to filter larger impurities in the water, such as mud and dust; and the granular activated carbon filter layer 36 effectively absorbs foreign colors and odors, insoluble impurities, and soluble impurities in the water.

[0040] A movable window cleaning assembly is provided below the transparent window 30. The window cleaning assembly is connected to the linear motor, and is controlled by the linear motor 39 to make reciprocating motion and clean the transparent window 30 through the cleaning brush 38. The transparent window 30 is cleaned by the window cleaning assembly package to ensure the cleanliness of the transparent window 30, and to ensure that the operator can normally see the cleanliness of the surface of the pressure roller 9. When there is residual glue or impurities on the surface of the pressure roller 9, it is cleaned.

[0041] The window cleaning assembly includes a guide rail motor 37 and a cleaning brush 38. The cleaning brush 38 is mounted on a linear motor 39, and the linear motor 39 is connected to the guide rail motor 37 through a slider. When the cleaning brush 38 is in the first cleaning state, the linear motor 39 is located close to the transparent window 30, and only the linear motor 39 is started to control the cleaning brush 38 to reciprocate, and the transparent window 30 is wiped in the moving state. When the cleaning brush 38 is in the second cleaning state, the guide rail motor 37 is started to work, the slider slides on the guide rail, and the linear motor 39 slides with the slider. When the linear motor 39 is located close to the pressure roller 9 and reaches the second cleaning position, the guide rail motor 37 stops working, and the linear motor 39 is started to control the cleaning brush 38 to reciprocate on the linear motor 39 to clean the residual glue and impurities on the pressure roller 9. At the same time, when cleaning, there may be residual glue and impurities falling from the cleaning brush 38, which can directly fall into the guide groove 33 located below.

[0042] When the hot pressing equipment designed by the present technical solution utilizes clean wastewater for optimized cooling, when the operator observes residual glue and impurities on the pressing roller 9 from the transparent window 30, the operator manually controls the hand control handle 18 to move the cleaning arm 15 to a position where the cleaning nozzle 14 can flush the residual glue and impurities, and flushes and cleans the pressing roller 9. The wastewater generated after flushing and cleaning drips into the guide groove 33, and the wastewater containing residual glue and impurities flows into the filter box 42 through the guide pipe 19. It is worth noting that the horizontal height of the guide groove 33 is higher than the horizontal height of the filter box 42. The wastewater flows smoothly to the filter box 42 through the guide pipe 19 under the action of gravity, and the wastewater is filtered in the filter box 42 to separate the residual glue and impurities and store them in the circulation collection In the collection part 44, the clean water obtained through the filter layer passes through the water collection part through the outlet pipe 43. The clean water in the outlet pipe 43 that has completed filtering is pumped by a water pump (not shown) and sent to the water storage tank 20. The temperature of the liquid gradually decreases during the process of flowing into the filter box 42 and the natural cooling process of the liquid during the filtering process. The temperature also continues to decrease during the water storage process of the water storage tank 20. The water pump extracts the clean water in the water storage tank 20 through the water pipe and sends it to the cooling element 21 to assist in cooling the cooling roller 10. After the clean water in the cooling element 21 is auxiliary cooled, the clean water after absorbing heat is sent back to the water storage tank 20 through another water pipe connected to the water storage tank 20. In this water flow reflux, because the horizontal height of the cooling element 21 is higher than the horizontal height of the water storage tank 20, a water pump can be omitted. At the same time, the clean water in the water storage tank 20 can also be pumped by the water pump through the water pipe and sent to the cleaning nozzle 14, and the cleaning nozzle 14 is supplied with water for cleaning the pressing roller 9. When the operator sees that the view of the transparent window 30 is blurred, the linear motor 39 is started to control the cleaning brush 38 to reciprocate and wipe the transparent window 30. When the operator can still see stains on the pressure roller 9 from the transparent window 30 after flushing the pressure roller 9, the guide motor 37 is started to drive the cleaning brush 38 to move toward the pressure roller 9. When the guide motor 37 reaches the position where the pressure roller 9 can be wiped, the linear motor 39 is started to control the cleaning brush 38 to reciprocate and wipe the pressure roller 9.
