Description
Technical Field
[0001] The utility model relates to the technical field of coating machines, in particular to a coating machine for PVC tarpaulin. Background Art
[0002] PVC tarpaulin, also known as waterproof cloth, is a high-strength waterproof material with good toughness and softness. PVC tarpaulin is used in logistics transportation, earthquake relief, home travel, etc. The common PVC tarpaulin processing process requires the use of a coating machine for brushing work.
[0003] Most of the existing PVC tarpaulin coating machines do not have a cleaning function and cannot clean the surface of the tarpaulin before painting, which causes dust to easily accumulate on the surface of the tarpaulin that needs to be painted. Excessive dust can easily affect the coating quality and thus affect work efficiency. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a coating machine for PVC tarpaulin to solve the problem that most of the existing PVC tarpaulin coating machines mentioned in the above background technology do not have a cleaning function and cannot clean the surface of the tarpaulin before painting, resulting in dust easily accumulating on the surface of the tarpaulin to be painted, and the large amount of dust easily affects the coating quality, thereby affecting the work efficiency.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a coating machine for PVC tarpaulin, comprising a base, a slurry box is fixedly connected to the middle side of the top of the base, a lower pressure roller is rotatably connected to the inner bottom of the slurry box, an extrusion roller is rotatably connected to the inner top of the slurry box, a support frame is fixedly connected to the right side of the top of the base, a guide roller 2 is rotatably connected to the inner side of the top of the support frame, a winding roller is arranged at the right end of the top of the base, a servo motor is fixedly connected to the front end of the winding roller, a mounting frame is fixedly connected to the left side of the top of the base, a guide roller 1 is rotatably connected to the inner upper side of the mounting frame, a mounting plate is fixedly connected to the top left end of the mounting frame, a cleaning cotton 1 is fixedly connected to the bottom of the mounting plate, a sliding rod is slidably connected to the top of the mounting plate, a pressure block is fixedly connected to the top of the sliding rod, a limiting spring is fixedly connected to the bottom of the sliding rod, and a bottom plate is fixedly connected to the top of the bottom plate.
[0006] Preferably, the number of the squeezing rollers is two, the two squeezing rollers are symmetrically distributed on both sides of the top of the slurry box, and the two squeezing rollers are in contact with each other.
[0007] By adopting the above technical solution, squeezing rollers, a slurry box, etc. are arranged for use in combination. When the tarpaulin moves between the two squeezing rollers, the two squeezing rollers will be driven to rotate. The squeezing rollers rotate and squeeze the excess slurry on the tarpaulin to the lower side of the tarpaulin. The slurry squeezed to the lower side then flows to the surface of the tarpaulin on the lower side and is coated again, thereby ensuring uniform coating of the tarpaulin and improving the coating quality.
[0008] Preferably, the number of the sliding bars is two, and the two sliding bars are respectively distributed on the front and rear sides of the mounting plate, and the two sliding bars both penetrate the top wall of the mounting plate and extend to the outside of the bottom of the mounting plate.

[0011] By adopting the above technical scheme, cleaning cotton 1 and cleaning cotton 2 are arranged to be used in conjunction with a slide rod and a limit spring. The limit spring stretches and then pushes the slide rod upward through the pressure block. The slide rod then drives cleaning cotton 2 to fit tightly with cleaning cotton 1, thereby clamping the upper and lower surfaces of the tarpaulin. When the tarpaulin moves, the dust on the surface of the tarpaulin will be cleaned by cleaning cotton 1 and cleaning cotton 2, thereby improving the coating quality and working efficiency.
[0012] Preferably, the output end of the servo motor is fixedly connected to the front side of the winding roller.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The coating machine of the PVC tarpaulin is used by setting cleaning cotton 1, cleaning cotton 2 and the like to cooperate with a slide bar and a limit spring. The limit spring stretches and then pushes the slide bar to move upward through a pressure block. The slide bar then drives the cleaning cotton 2 to fit closely with the cleaning cotton 1, thereby clamping the upper and lower surfaces of the tarpaulin. When the tarpaulin moves, the dust on the surface of the tarpaulin will be cleaned by the cleaning cotton 1 and the cleaning cotton 2, thereby improving the coating quality and the work efficiency.
[0015] 2. The coating machine of the PVC tarpaulin is used in conjunction with an extrusion roller, a slurry box, etc. When the tarpaulin moves between the two extrusion rollers, the two extrusion rollers will be driven to rotate. The rotation of the extrusion rollers will squeeze the excess slurry on the tarpaulin to the lower side of the tarpaulin. The slurry squeezed to the lower side will then flow to the surface of the tarpaulin on the lower side and be coated again, thereby ensuring uniform coating of the tarpaulin and improving the coating quality.
