Description

Technical Field

[0001] The invention relates to the technical field of spraying, in particular to a rainproof plastic spraying production line. Background Art

[0002] The rainproof plastic spraying production line is an automated production line specially used for waterproof spraying treatment on plastic surfaces. Its main function is to spray the rainproof agent evenly on the surface of plastic products through a precise spraying process, thereby forming a protective film with waterproof function on its surface. This protective film can significantly improve the weather resistance, UV resistance and service life of plastic products. Especially when used outdoors or in humid environments, it can effectively prevent water penetration, prevent the product from being damaged by water, and extend its service life. Through this process, the produced plastic parts can better resist rain, moisture, pollutants and wear and tear in daily use.

[0003] A Chinese patent with announcement number CN110694840B discloses a spraying production line, including a spraying room, two groups of spraying devices and a driving mechanism. Both groups of spraying devices include a number of sliding columns. The workpiece will abut against all matching parts and push all sliding columns to slide away from the workpiece. The elastic part will cause the matching parts to press against the workpiece, and then the plug-in assembly will plug and fix all the sliding columns, so that a certain distance is always maintained between the spray gun and the workpiece, ensuring uniform spraying of the workpiece by the spray gun.

[0004] A Chinese patent with announcement number CN115445843B discloses a spray chamber, including an outer wall of the spray chamber, on which an air inlet device for diffusing airflow is provided. The airflow outside the spray chamber is pulled by the air inlet device and pressed down to the spraying station through a first filter, so that the paint mist sprayed by the spray device is evenly sprayed on the workpiece under wind pressure, thereby preventing the paint mist from rebounding when the spray device sprays on the workpiece.

[0005] The above and similar prior arts can, to a certain extent, solve the problem of achieving the rainproof agent spraying effect of plastics. The existing spraying equipment usually completes the waterproofing treatment by spraying on both sides of the plastic. Although this method can achieve a certain spraying effect in some cases, it is easy to cause unevenness in the spraying process, especially in the complex parts and corners of plastic parts. Since the spraying of these positions is difficult, the spraying agent is difficult to completely cover, and leakage may occur, thereby affecting the final waterproofing effect, resulting in unevenness of the waterproof film, and then reducing the overall weather resistance and service life of the plastic products. In addition, the sprayed paint falls to the ground, which not only increases the production cost, but also has a negative impact on the environment. The volatile solvents and other chemicals in the spraying process may form harmful gases. These gases not only pose a potential hazard to the health of the operators, but also may pollute the working environment and affect the air quality and production safety of the workshop. Therefore, improving the spraying equipment and optimizing the spraying method to achieve a more uniform and efficient spraying effect and effectively reduce the waste of paint and the emission of harmful gases are the current rainproof plastic spraying production lines that need to be urgently solved.

[0006] Therefore, the present invention provides a rainproof plastic spraying production line which can spray plastics comprehensively and recycle the unsprayed coatings. Summary of the invention

[0026] In this embodiment, a driving mechanism 12 is provided inside the inner C ring 3 and the outer C ring 4, and the driving mechanism 12 includes two groups of squeezing rollers 124; the driving mechanism 12 is configured to rotate through the two groups of squeezing rollers 124, and to drive the cross belt 6 to move by friction with the cross belt 6, and the driving mechanism 12 also includes a plurality of driving shafts 121, and the plurality of driving shafts 121 respectively penetrate the top of the outer C ring 4 through bearings, and the top of the driving shaft 121 penetrates the top of the open tube 1 through bearings, and a plurality of synchronous motors 122 are fixedly installed on the top of the open tube 1, and the output end of the synchronous motor 122 is fixedly connected to the top of the driving shaft 121, and a plurality of driven shafts 121 are installed on the top of the inner C ring 3 through bearings. The top of the driven shaft 123 is rotatably mounted on the inner side of the top wall of the open tube 1 through a bearing, and each group of squeezing rollers 124 has two. A group of squeezing rollers 124 is fixedly mounted on the outer side of the driving shaft 121 and the driven shaft 123 respectively. The two squeezing rollers 124 on the outer side of the driving shaft 121 are respectively located on the inner side and top of the outer C ring 4, and the two squeezing rollers 124 on the outer side of the driven shaft 123 are respectively located on the inner side and top of the inner C ring 3.

[0027] Specifically, multiple synchronous motors 122 can drive multiple driving shafts 121 to rotate synchronously at the same time. The driving shaft 121 and the driven shaft 123 can provide stable support for the large gear 125. The meshing of the two large gears 125 can ensure that the driving shaft 121 and the driven shaft 123 can rotate synchronously in opposite directions, so that the extrusion rollers 124 on both sides of the cross belt 6 can rotate synchronously in opposite directions.

[0028] In this embodiment, a sprayer 22 is fixedly installed on one side of the spray chamber 1003, and a delivery pipe 23 is fixedly installed on one side of the sprayer 22. The delivery pipe 23 runs through the interior of the spray chamber 1003, and the delivery pipe 23 is located between two bevel gears 19. A plurality of atomizing nozzles 24 are installed inside the delivery pipe 23. A reflux pump 25 is fixedly installed on one side of the sprayer 22 close to the spray chamber 1003, and one end of a reflux pipe 26 is fixedly installed at the input end of the reflux pump 25. The other end of the reflux pipe 26 runs through the interior of the open pipe 1 and is communicated with the collecting tank 14.

[0029] Specifically, the spray chamber 1003 can provide a space for the collection tank 14, and the collection tank 14 can provide a collection space for the paint. The inner side of the bottom wall of the collection tank 14 is inclined, so that the collected paint can be gathered in the middle position of the collection tank 14. The collection tank 14 can provide a placement space for the filter screen 15, and the filter screen 15 can filter solid impurities in the paint. The reflux pump 25 can work according to the amount of paint inside the collection tank 14, so that the paint in the collection tank 14 can be regularly transported back to the sprayer 22 through the reflux pipe 26. The heating chamber can provide heat to the inner wall of the spray chamber 1003 through the heating rod, so that the paint on the inner wall of the spray chamber 1003 will not solidify due to the low temperature, so that the paint on the inner wall of the spray chamber 1003 can be recovered in liquid form.

[0030] In this embodiment, a column groove 81 is provided inside the hanger 8, and movable holes 82 are respectively provided on both sides of the hanger 8, and the movable holes 82 are communicated with the column groove 81, and the bottoms of the inner C ring 3 and the outer C ring 4 are provided with inclined plates 13, and the inclined plates 13 are located on the inner side of the spray chamber 1003. A vibration mechanism 10 is provided inside the hanger 8, and the vibration mechanism 10 is equipped to switch the interference rod 103 and the inclined plate 13 between the interference state and the non-interference state through the rotation movement of the hanger 8, thereby completing the vibration operation; the vibration mechanism 10 includes two resistance rods 103, and the vibration mechanism 10 also includes a vibration spring 101. One end of the vibration spring 101 is fixedly installed on the inner side of the bottom wall of the column groove 81, and the other end of the vibration spring 101 is fixedly installed with a top plate 102. The two resistance rods 103 are respectively fixedly installed on both sides of the top plate 102, and the resistance rods 103 are located on the inner side of the movable hole 82. One end of a connecting rod 104 is fixedly installed on the bottom of the top plate 102, and the other end of the connecting rod 104 passes through the bottom of the column groove 81 and is fixedly installed with a clamp 11.

[0031] Specifically, after the atomizing nozzle 24 sprays the paint, a spraying area will be formed. The right end of the inclined plate 13 coincides with the spraying area, and the leftmost end of the inclined plate 13 exceeds the spraying area. When the plastic shell leaves the spraying area, it will vibrate for the last time, so that the excess paint on the surface of the plastic shell can be shaken off to prevent excessive rainproof agent from being concentrated on the surface of the plastic shell to form bulges. When the plastic shell moves into the spraying room 1003 with the rotation of the cross belt 6, the rotating plastic shell can fully contact with the atomized rainproof agent, thereby achieving comprehensive spraying. At the same time, the rotating hanger 8 drives the resistance The rod 103 contacts the inclined surface of the inclined plate 13, and the hanger 8 continues to rotate and move, so that the contact rod 103 drives the top plate 102 to move downward under the contact action of the inclined plate 13, and the vibration spring 101 is squeezed and compressed and deformed by the top plate 102. When the two contact rods 103 rotate to be parallel to the gap between the two oblique sides, the contact rod 103 is in a non-contact state, so that the contact rod 103 loses the extrusion, and the vibration spring 101 drives the top plate 102 to vibrate up and down, so that the top plate 102 drives the clamp 11 and the plastic shell to vibrate up and down through the connecting rod 104, so that the spraying effect is more uniform.

[0032] In this embodiment, a collecting groove 14 is opened on the inner side of the bottom wall of the spray chamber 1003, and a filter screen 15 is arranged on the inner side of the collecting groove 14. Two groups of bearing rings 16 are fixedly installed on the inner wall of the spray chamber 1003, and each group of bearing rings 16 has two bearing rings. A rotating ring 17 is rotatably installed on the inner side of the bearing ring 16, and a plurality of scrapers 18 are fixedly installed between the two rotating rings 17 of each group. The scrapers 18 are in contact with the inner wall of the spray chamber 1003. A bevel gear 19 is fixedly installed on the side where the two rotating rings 17 in the middle are close to each other. A driving motor 21 is fixedly installed on the top of the spray chamber 1003, and the output end of the driving motor 21 passes through the top of the spray chamber 1003. A bevel gear 20 is fixedly installed on the outer side of the output end of the driving motor 21 located on the inner side of the spray chamber 1003, and the bevel gear 20 is respectively meshed with the two bevel gears 19.

[0033] Specifically, a heating device is provided inside the spray chamber 1003 so as to heat the inner wall of the spray chamber 1003 to prevent the paint from solidifying. The bearing ring 16 can provide rotational support for the rotating ring 17, and the rotating ring 17 can provide rotational support for the scraper 18. The two rotating rings 17 near the middle can provide stable support for the bevel gear 19. The bevel gear 20 is driven to rotate by the driving motor 21, and the rotating rings 17 on the left and right sides are driven to rotate by the meshing action of the bevel gear 20 and the bevel gear 19. The rotating ring 17 drives the scraper 18 to rotate at the same time, so that the scraper 18 scrapes off the rain repellent on the inner wall of the spray chamber 1003, and the rain repellent enters the inner side of the collecting tank 14 under the action of the scraper 18.

[0034] In this embodiment, a cleaning brush 27 is fixedly installed on the inner wall of the cleaning chamber 1002 on the side close to the inner diameter through a plurality of support rods, an air purifier 29 is fixedly installed on the inner wall of the cleaning chamber 1002 on the side close to the outer diameter, a dryer 28 is fixedly installed on the inner wall of the drying chamber 1004 on the side close to the inner diameter, and another air purifier 29 is fixedly installed on the inner wall of the drying chamber 1004 on the side close to the outer diameter.

[0035] Specifically, the bristles on the surface of the cleaning brush 27 are relatively long, so that they can fully provide a cleaning effect for the plastic shell. The cleaning chamber 1002 and the drying chamber 1004 can provide a stable support for the air purifier 29. At the same time, the cleaning chamber 1002 and the drying chamber 1004 provide a sufficiently long flow channel for the irritating gas in the open tube 1, so that the air purifier 29 can fully absorb and purify the irritating gas. The dryer can blow out hot air, so that the hot air flows on the surface of the plastic shell for drying, and blows toward the air purifier 29 to improve the purification effect.

[0036] Embodiment 2: Fig.14 As shown, another tooth groove is opened on the outer side of the cross belt 6 near the top, and a long rotating rod is rotated on the top of the outer C ring 4 through a bearing, and another meshing tooth 9 is fixedly installed on the outer side of the long rotating rod, and the meshing tooth 9 meshes with the tooth groove of the cross belt 6. The bevel gear is rotatably installed on the top of the spray chamber 1003 through the short rotating rod, and the long rotating rod and the short rotating rod are transmitted by gear meshing. When the cross belt 6 rotates, the long rotating rod is driven to rotate by the meshing action of the tooth groove, and then the short rotating rod is driven to rotate by the meshing transmission action of the gear, thereby driving the bevel gear to rotate, so that the scraper 18 rotates to scrape the inner wall of the spray chamber 1003.

[0037] Working principle: the staff starts the synchronous motor 122, so that multiple synchronous motors 122 work at the same time, the synchronous motor 122 drives the driving shaft 121 to rotate, and at the same time drives the driven shaft 123 to rotate in the opposite direction under the meshing action of the large gear 125, so that the driving shaft 121 and the driven shaft 123 rotate in opposite directions at the same time, the driving shaft 121 and the driven shaft 123 drive the squeezing roller 124 to rotate, so that the squeezing roller 124 drives the cross belt 6 to move by friction, and the cross belt 6 moves along the inner C ring 3 and the outer C ring 4. The cross belt 6 drives the hanger 8 to move through the bearing seat 7. During the movement of the hanger 8, due to the meshing action of the outer meshing teeth 9 of the hanger 8 and the tooth groove, the hanger 8 rotates during the movement; The staff is located in the material changing area 1001 to load and unload materials. The sprayed plastic shell is first disassembled by the clamp 11 on the hanger 8, and the plastic shell to be sprayed is clamped. Then the hanger 8 drives the plastic shell to rotate and move. The hanger 8 drives the plastic shell to enter the inner side of the cleaning room 1002 first, so that the plastic shell contacts the cleaning brush 27 in the cleaning room 1002. The rotation of the plastic shell enables the cleaning brush 27 to fully clean the surface of the plastic shell. The plastic shell moves into the spraying room 1003 as the cross belt 6 rotates, and the sprayer 22 starts to spray the rainproof agent through the atomizing nozzle 24. The rotating plastic shell can fully contact with the atomized rainproof agent, thereby achieving comprehensive spraying. At the same time, the rotating hanger 8 drives the resistance rod 103 to contact the inclined surface of the inclined plate 13. The hanger 8 continues to rotate and move, so that the resistance rod 103 drives the top plate 102 to move downward under the resistance of the inclined plate 13. The vibration spring 101 is squeezed and compressed by the top plate 102. When the two resistance rods 103 rotate to When the contact rod 103 is parallel to the gap between the two beveled edges, the contact rod 103 is in a non-contact state, so that the contact rod 103 loses its extrusion, and the vibration spring 101 drives the top plate 102 to vibrate up and down, so that the top plate 102 drives the clamp 11 and the plastic shell to vibrate up and down through the connecting rod 104, so that the spraying effect is more uniform. The plastic shell vibrates multiple times when passing through the spraying area. When the plastic shell leaves the spraying area, it will vibrate for the last time, so that the excess paint on the surface can be shaken off, and the excessive rainproof agent on the surface of the plastic shell is prevented from being concentrated and attached to form bulges; The rainproof agent not sprayed on the surface of the plastic shell falls on the inner wall of the spray chamber 1003, and the driving motor 21 is started, so that the driving motor 21 drives the bevel gear 20 to rotate, and the meshing action of the bevel gear 20 and the bevel gear 1 19 drives the rotating rings 17 on the left and right sides to rotate, and the rotating ring 17 drives the scraper 18 to rotate at the same time, so that the scraper 18 scrapes the rainproof agent on the inner wall of the spray chamber 1003, and the rainproof agent enters the inner side of the collecting tank 14 under the action of the scraper 18, and converges at the middle position under the action of the inclined surface of the collecting tank 14, and the reflux pump 25 is started, so that the reflux pump 25 returns to the inner side of the sprayer 22 through the reflux pipe 26, so that the rainproof agent not sprayed can be recycled and reused; The plastic shell continues to rotate and move to the inner side of the drying chamber 1004 with the cross belt 6. At this time, the dryer 28 works to blow out hot air, so that the hot air flows on the surface of the plastic shell for drying. The rotating plastic shell can be dried in all directions. At the same time, the two air purifiers 29 work at the same time to purify the air in the cleaning chamber 1002 and the drying chamber 1004, making it difficult for the irritating gas inside the open tube 1 to escape to the outside through the cleaning chamber 1002 and the drying chamber 1004.
