Description

Technical Field

[0001] This utility model relates to the field of casting machine technology, specifically to a roller surface cleaning device for a polymer plastic wrap casting machine. Background Technology

[0002] The polymer plastic wrap casting machine is a key piece of equipment for producing polymer plastic wrap. It uniformly casts molten polymer raw materials onto cooling rollers, and through a series of processes such as rapid cooling and shaping, traction, and slitting, produces plastic wrap with good transparency, flexibility, and barrier properties. The equipment uses a precise temperature control system to ensure stable molten state of the raw materials, and is equipped with a high-precision casting die head to ensure uniform film thickness. Combined with an efficient cooling device and traction mechanism, it can achieve continuous and automated production, greatly improving production efficiency and product quality. It is widely used in the processing and production of plastic wrap in food preservation, household daily necessities, and other fields.

[0003] In the existing technology, during the continuous production process of polymer plastic wrap casting machine, the roller, as the core component in contact with the molten film material, has low molecular weight volatiles generated at high temperatures that adhere to the roller surface. Over time, these volatiles accumulate and form stubborn stains, causing spots to appear on the plastic wrap that is subsequently formed. If the roller surface is not cleaned for a long time during use, it will affect the quality of the product.

[0004] Therefore, a roller surface cleaning device for a polymer plastic wrap casting machine is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a roller surface cleaning device for a polymer plastic wrap casting machine, which solves the technical problem that the quality of the product will be affected if the roller surface is not cleaned for a long time, and achieves the purpose of cleaning and drying.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a roller surface cleaning device for a polymer plastic wrap casting machine, comprising a base plate, a cleaning component disposed on the surface of the base plate, a drying component disposed on the surface of the base plate, a roller disposed on the surface of the cleaning component, and connecting shafts fixedly installed on both sides of the roller.

[0007] Preferably, the cleaning components specifically include: a recessed frame, fixedly installed on both sides of the base plate; a support frame, fixedly installed on the top of the recessed frame; a U-shaped placement rack, fixedly connected to the surface of the support frame; a side plate, fixedly installed on the top of the support frame; a water tank, disposed at the bottom of the inner wall of the recessed frame; and water pipes, respectively disposed on the top of the base plate.

[0008] Preferably, the inner wall of the U-shaped placement rack is slidably connected to the outer wall of the connecting shaft, a support base is fixedly installed on one side of the support rack, and a motor is fixedly installed on the top of the support base.

[0009] Preferably, an electromagnet disk is fixedly installed at the output end of the motor, the other side of the electromagnet disk is attracted to the other end of the connecting shaft, and a V-shaped collecting hopper is rotatably connected to the inner wall of the side plate.

[0010] Preferably, a second motor is fixedly installed on the outer side of the side plate, and a rotating shaft is fixedly installed on the output end of the second motor. The other end of the rotating shaft movably passes through the outer side of the side plate and extends to the inner side of the side plate, where it is fixedly installed on the other side of the V-shaped collection hopper.

[0011] Preferably, cleaning sponge rollers are fixedly installed at equal intervals on the inner wall of the V-shaped collection hopper. Through holes are opened on both sides of the V-shaped collection hopper, and a spray plate is fixedly installed between the inner walls of the through holes. One end of the water pipe connects to the other side of the water tank and extends into the tank. A pump is installed at one end of the water pipe, and the other end of the water pipe is connected to the surface of the spray plate. Through this device, the cleaning sponge rollers inside the V-shaped collection hopper contact the roller surface, and the cleaning water sprayed from the spray plate thoroughly wipes and rinses the roller, effectively removing residual polymer material debris, oil, and other impurities from the roller surface. The V-shaped structure design allows the cleaning sponge rollers to conform to the roller's curvature, ensuring thorough cleaning without dead angles, improving the cleanliness of the roller surface, and thus ensuring stable quality of the subsequent production of cling film and reducing the risk of roller contamination. To address film surface defects caused by dyeing, motor one drives an electromagnet to engage the coupling shaft, causing the roller to rotate. Motor two drives a V-shaped collection bucket to rotate and adjust the cleaning angle. A pump automatically draws water from the tank and sprays it through a spray plate. The entire cleaning process requires no manual operation, reducing labor intensity and avoiding problems such as improper operation and untimely cleaning that may occur during manual cleaning. This improves the efficiency and stability of the cleaning operation. Components such as the recessed frame and support frame provide stable support for the device. The U-shaped placement frame slides with the coupling shaft, which facilitates the installation and disassembly of the roller and ensures stable rotation of the roller during the cleaning process. The compact layout of each component and high space utilization make it well-suited to the working environment of the polymer preservation film casting machine. It will not interfere with the operation of the original unit, thus achieving the desired cleaning effect.

[0012] Preferably, the drying assembly specifically includes: a support rod, fixedly installed on the top of the support frame; an air jet plate, fixedly installed between the inner sides of the support rod; and air inlets, evenly spaced on one side of the air jet plate.

[0013] Preferably, a support recess is fixedly installed on the back of the base plate, and a hot air blower is fixedly installed between the inner walls of the support recess. A duct is installed between the top of the hot air blower and the air jet plate. After cleaning is completed by the cleaning component, the drying component immediately starts working. The hot air generated by the hot air blower is delivered to the air jet plate through the duct and blown evenly onto the surface of the roller through the air outlet, quickly removing the moisture on the roller and avoiding moisture residue from affecting the forming quality of the cling film. The integrated design of cleaning and drying eliminates the need for additional roller transfer or waiting for natural drying, shortens the time for resuming production after cleaning, ensures continuous production of the casting machine, and thus achieves the drying effect.

[0014] This invention provides a roller surface cleaning device for a polymer plastic wrap casting machine. It has the following beneficial effects:

[0015] (1) This utility model can clean the roller by setting up a cleaning component. When the electromagnet is energized, the connecting shaft is attracted. The motor is started to drive the connecting shaft and the roller to rotate. The pump is started to draw water from the water tank and spray it on the surface of the roller through the spray plate. Then the motor is started to drive the V-shaped collection bucket to rotate slightly, so that the cleaning sponge roller on one side cleans the surface of the roller, improves the cleanliness of the roller surface, and thus ensures the stable quality of the subsequent production of cling film, thereby achieving the cleaning effect.

[0016] (2) This utility model can dry the cleaned surface by setting a drying component. When the hot air blower is started, the hot air enters the jet plate through the air pipe and dries the cleaned surface through the air port, quickly removing the moisture on the roller and avoiding moisture residue from affecting the forming quality of the cling film, thereby achieving the drying effect.
