Description

Technical Field

[0001] The invention relates to the technical field of dipped cloth processing equipment, in particular to a dust-free device for producing dipped cloth. Background Art

[0002] Dipped cloth is a composite material. Its production process involves immersing the cloth base material in glue, allowing the glue to penetrate into the interior of the cloth, and then combining the cloth and the glue into one through heating, compacting, drying and other processes. As a composite material with excellent performance, dipped cloth plays an important role in many fields, such as being used to make industrial products such as conveyor belts and transmission belts, and as a protective material for various mechanical equipment.

[0003] For example, the publication number is CN213810973U, which discloses a dust-free device for the production of dipped rubber cloth, comprising an air suction pipe, a threaded ring being threadedly connected to the bottom of the air suction pipe, a filter mesh ring being fixedly connected to the bottom of the threaded ring, a rubber disc being rotatably connected to the bottom of the air suction pipe, and the rubber disc being movably connected to the threaded ring, two mounting blocks being fixedly connected to the bottom of the air suction pipe, side walls of the mounting blocks being rotatably connected to a rotating shaft, a fixed block being arranged between the mounting blocks, the rotating shaft being rotatably connected to the fixed block, and a slot corresponding to the filter mesh ring being provided on adjacent sides of the fixed blocks, and a rotating rod being fixedly connected to the bottom of the rubber disc, which solves the problem that the filter mesh at the air inlet cannot be replaced quickly and effectively, maintenance is very inconvenient, and efficiency is low.

[0042] The six groups of transmission gears 34 are all meshed and connected with the driving gear 36, and the transmission gear 34 is adapted to the docking card slot 52 through the docking card shaft 35 and then slidably engaged with the transmission card shaft 51, which can effectively improve the convenience of docking the docking card shaft 35 with the transmission card shaft 51 through the docking card slot 52, facilitate the subsequent quick and convenient disassembly of the transmission card shaft 51 and the docking card shaft 35, and improve the convenience of subsequent replacement of the filter guide plate 54.

[0043] The lower end surface of the transmission card shaft 51 is slidably connected with the bearing card seat 58 through the connecting swivel seat 59, and the limiting card sleeve 53 is slidably connected to the inside of the sealing ventilation seat 510 through the transmission card shaft 51, and the filter guide plate 54 is fit-connected with the inner wall of the sealing ventilation seat 510.

[0046] The sealed ventilation seat 510 is adapted to the docking slot 44 through the plug-in card shaft 55 and then sealed and fixedly connected to the ventilation guide tube 43. When the ventilation guide tube 43 and the sealed ventilation seat 510 are docked, the sealed ventilation seat 510 can be aligned with the docking card slot 44 through the plug-in card shaft 55, which effectively improves the accuracy of subsequent positioning and guiding of the sealed ventilation seat 510 and the ventilation guide tube 43 and the stability after subsequent docking.

[0047] Working principle: Before use, the staff can connect the external exhaust gas supply pipe with the upper air duct 511, and then connect the exhaust pipe with the lower air duct 511. When processing the exhaust gas from the production of dipped cloth, the staff can start the servo motor 2. At this time, the servo motor 2 can provide power for the L-shaped reduction motor 1, so that the L-shaped reduction motor 1 can synchronously drive the driving gear 36 at the bottom to rotate. At the same time, when the driving gear 36 rotates, it can synchronously drive the six groups of transmission gears 34 on the side to rotate. At the same time, the transmission gear 34 can pass through the limit of the docking card shaft 35 and the docking card slot 52 at the bottom, and then synchronously drive the six groups of transmission card shafts 51 to rotate at high speed. The transmission card shaft 51 can synchronously drive multiple groups of filter guide plates 54 to rotate at high speed inside the sealed ventilation seat 510 through the limit sleeve 53, thereby quickly filtering the exhaust gas transported by the air duct 511. The high-speed rotating filter guide plates 54 can increase the contact surface with the exhaust gas. The filter guide 54 is replaced after a long period of use. At this time, the staff can first start the lifting cylinder 42, and the lifting cylinder 42 can drive the fixed guide seat 32 to lift as a whole through the support card seat 41. At this time, the docking card shaft 35 is released from the docking card slot 52, and then the reduction motor 46 is started. The reduction motor 46 can drive the guide turntable 6 at the bottom to rotate. At the same time, the guide turntable 6 can pass through the six groups of arc slide grooves 7 and the sliding limit of the support slide shaft 56, thereby synchronously driving the six groups of sealing ventilation seats 510 to synchronously centrifugal displacement, so that the sealing ventilation seat 510 can drive the limiting sleeve 53 and the filter guide plate 54 to move outward synchronously, thereby providing enough space for the subsequent replacement of the filter guide plate 54. Then the external robotic arm can quickly replace the filter guide plate 54 that needs to be replaced. After the replacement is completed, the sealing ventilation seat 510 can be sealed and connected to the outside of the ventilation guide tube 43 again by aligning the plug-in card shaft 55 with the docking card slot 44.
