Description

Technical Field

[0001] The utility model belongs to the technical field of artificial leather production, and in particular relates to a calender roller cleaning device for a PVC artificial leather calender. Background Art

[0002] Artificial leather is a plastic product that looks and feels like leather and can be used instead of leather. It is usually made of fabric as the base, coated with synthetic resin and various plastic additives. In the process of artificial leather production, the artificial leather after coating needs to be calendered by a calender. The calender roller on the calender will be contaminated with impurities after use, so it needs to be cleaned regularly.

[0003] The existing treatment methods are mostly water washing. The utility model patent with the publication number CN219805047U discloses a calender roller cleaning device for a PVC artificial leather calender, including two relatively arranged L-shaped brackets, a cleaning component is arranged between the two L-shaped brackets, and the cleaning component includes a cleaning main pipe, a wiping sponge, and a lifting rectangular frame. The cleaning main pipe is connected to a cleaning branch pipe, and the cleaning branch pipe is connected to a cleaning nozzle. The wiping sponge is connected to a fixed seat, and the fixed seat is connected to a rotating arm. The rotating arm is connected to the L-shaped bracket through a rotating shaft. The lifting rectangular frame is connected to the L-shaped bracket through a lifting component, and the lifting rectangular frame is connected to a wiper plate through a translation component. The utility model can realize the cleaning and wiping of the calender roller, and can periodically squeeze water from the wiping sponge to ensure the cleaning effect, greatly improve the thoroughness of cleaning, avoid the surface of the artificial leather from being affected by impurities, and ensure the calendering quality. However, in this solution, after the wiping sponge has been used for a period of time and its water absorption capacity is saturated, it is squeezed out and the sponge is returned to continue wiping after squeezing out the water. This can only achieve periodic alternating squeezing of water from the two wiping sponges. If the two wiping sponges are full of water at the same time, they cannot be squeezed out at the same time, which affects the efficiency of squeezing out water and wiping. It is inconvenient to use and the cleaning effect cannot be guaranteed.

[0004] Therefore, improvements are urgently needed. Utility Model Content

[0005] In view of the above-mentioned defects in the prior art, the utility model provides a calender roller cleaning device for a PVC artificial leather calender, comprising a cleaning mechanism, wherein the PVC artificial leather calender comprises an upper calender roller and a lower calender roller which are opposite to each other, the cleaning mechanism comprises a base plate, two support frames, two columns, two water spraying assemblies, two wiping assemblies and a water squeezing mechanism, the two support frames are respectively fixed at the left and right ends above the base plate, the two columns are respectively fixed on the inner sides of the two support frames, the two water spraying assemblies are respectively arranged on the outer sides of the two support frames, each water spraying assembly comprises a water tank installed on the base plate and a water supply pipe laid along the support frame, a water pump is arranged between the water supply pipe and the water tank, a plurality of nozzles are installed at the end of the water supply pipe, and the nozzles of the plurality of nozzles are respectively facing the upper calender roller and the lower calender roller.

[0006] The two wiping assemblies are divided into an upper wiping assembly and a lower wiping assembly, and the upper wiping assembly is located obliquely above the upper calendering roller, and the lower wiping assembly is located obliquely below the lower calendering roller. The upper wiping assembly and the lower wiping assembly each include two rotating rods, two mounting plates and a servo motor. The two rotating rods are respectively rotatably connected to the inner sides of the two columns, and the two rotating rods are parallel to each other. The two mounting plates are respectively arranged on the front and rear sides of the rotating rods, and the two mounting plates are parallel to each other. The left and right sides of the two mounting plates are respectively fixedly connected to the ends of the two rotating rods, and the rotating rods and the mounting plates are vertically connected. A wiping sponge is arranged on each mounting plate, and the width of the wiping sponge is slightly larger than the width of the calendering roller. The servo motor is arranged on the outer side of the column to drive the rotating rod to rotate.

[0007] The water squeezing mechanism includes an upper water squeezing component and a lower water squeezing component with an axisymmetric structure in appearance, and the upper water squeezing component and the lower water squeezing component correspond to the upper wiping component and the lower wiping component respectively. The upper water squeezing component and the lower water squeezing component each include two fixed brackets, two synchronous cylinders and a water squeezing plate. The two fixed brackets are respectively fixed on the front sides of the two columns, and the two synchronous cylinders are respectively inclinedly arranged on the two fixed brackets. The left and right ends of the water squeezing plate are respectively fixedly connected to the piston rods of the two synchronous cylinders, and the width of the water squeezing plate is slightly larger than the width of the wiping sponge.

[0008] Optionally, the angle between the synchronous cylinder and the horizontal plane is 35°-45°.

[0009] Specifically, taking the upper wiping assembly and the upper water squeezing assembly as examples, when the servo motor drives the rotating rod to rotate to the same inclination angle as the synchronous cylinder, the synchronous cylinder can stretch the piston rod to drive the water squeezing plate to approach and squeeze the wiping sponge at the higher end, and can squeeze out the water in the wiping sponge.

[0011] Specifically, it is convenient to move.

[0012] Optionally, a water collecting tank is provided above the bottom plate.

[0013] Specifically, it facilitates the collection of waste water.

[0014] Optionally, a valve is also provided on the water supply pipe.

[0015] The utility model also includes other components that can enable the calender roller cleaning device for a PVC artificial leather calender to be used normally, which are all conventional technical means in the art.

After that, the two synchronous cylinders in the upper water squeezing assembly and the lower water squeezing assembly stretch the piston rod at the same time, drive the water squeezing plate to approach and squeeze the wiping sponge, squeeze out the water in the wiping sponge, and the squeezed waste water can be collected through the sump, while the wiping sponge at the other end of the rotating rod can continue to wipe and clean the calender roller.

[0017] The beneficial effects of the utility model are that the calendering roller can be rinsed and wiped clean by the water spraying component and the wiping component; the wiping sponge in the wiping component can be squeezed with water by the water squeezing mechanism, so that the wiping sponge maintains a high water absorption efficiency and improves the wiping and cleaning effect; in addition, the upper and lower wiping components and the two water squeezing components are independent of each other and do not affect each other. The wiping sponges that are already saturated with water in the two wiping components can be squeezed with water at the same time, or squeezed with water alternately, which improves the water squeezing and wiping efficiency, is flexible and convenient to use, and has a good cleaning effect.
