Description

Technical Field

[0001] This invention relates to a scraping-type synthetic leather rolling mechanism and its processing method. Background Technology

[0002] Polyurethane synthetic leather is a type of polyurethane elastomer. It boasts a soft luster and a genuine leather-like appearance, along with excellent adhesion to substrates, wear resistance, flexural strength, and aging resistance. It is gradually becoming an ideal substitute for natural leather. Processing polyurethane synthetic leather involves rolling, but during this process, some synthetic leather material adheres to the edges of the rollers. Over time, this material accumulates, requiring regular cleaning. Current cleaning methods are cumbersome, requiring manual labor, which is time-consuming and labor-intensive. Therefore, there is a need to improve the convenience and efficiency of roller cleaning. Summary of the Invention

The scraping assembly includes a perforated scraping ring, a sealing sleeve, a positioning plate, a suction pipe, an exhaust disc, an exhaust pipe, an air pump, and a traveling block. The perforated scraping ring is mounted on the outer periphery of one end of the rotating pressure roller. The sealing sleeve is mounted on the inner periphery of the perforated scraping ring. The traveling block is mounted on the upper side of the perforated scraping ring and slidably between the upper ends of the two side support plates. The other end of the rotating pressure roller is equipped with... A positioning plate is provided. Multiple suction pipes are fixedly installed around the positioning plate, with their outer ends extending to the outer side of a side support plate. An exhaust plate is installed on the outer side of the side support plate, and the outer ends of the suction pipes are connected to the inner side of the exhaust plate. An exhaust pipe is installed on the lower side of the exhaust plate, and an air pump is installed on the exhaust pipe. The traveling block drives a porous scraper ring to move from one end of the rotating pressure roller to the other end. The inner side of the porous scraper ring moves against the outer side of the rotating pressure roller, scraping away the attached waste material on the outer surface of the rotating pressure roller. The porous scraper ring drives the abutment sealing sleeve to move and abut against the side of the positioning plate, forming a waste adsorption cavity with the porous scraper ring, the abutment sealing sleeve, and the positioning plate. The air pump then draws out and discharges the attached waste material from the waste adsorption cavity.

[0006] Furthermore, the lifting conveying mechanism includes a lifting plate, a positioning frame, a drive wheel, a conveyor belt, a linkage rod, a transmission motor, and a lifting cylinder. The conveyor belt is installed on the lower side of the rotating pressure roller. A drive wheel is installed at each of the front and rear ends of the conveyor belt, and a linkage rod is installed between the drive wheels. A lifting cylinder is installed on both the front and rear sides of the positioning base. A lifting plate is installed on the upper end of the lifting cylinders. A positioning frame is installed on each of the upper sides of the lifting plate. The outer center of each drive wheel is rotatably engaged with the inner side of the positioning frame through a rotating column. The transmission motor is installed on the outer side of one positioning frame and is connected to the outer end of the rotating column of one drive wheel.

[0007] Furthermore, the inner side of the side support plate is provided with a sliding groove; the two sides of the lifting plate are respectively slidably engaged with the sliding groove by floating support rods.

[0008] Furthermore, an annular sealing ring is provided around the end of the abutting closed sleeve.

[0009] Furthermore, the upper end of the side support plate is provided with a fixing strip; the fixing strip is provided with a strip track; the upper end of the traveling block is slidably engaged with the strip track by a sliding block; a power screw is threaded onto the traveling block, and one end of the power screw is connected to a power motor through a power shaft; the power motor is fixedly installed on the outer side of the upper end of a side support plate.

[0010] Furthermore, a filter box is provided at the lower end of the exhaust pipe, and an exhaust pipe is provided on the outside of the filter box.

[0011] Furthermore, the porous scraper ring has multiple dense and breathable holes evenly distributed on it.

[0012] Furthermore, one end of the rotating pressure roller is provided with a positioning rotating column; the positioning rotating column is rotatably engaged with the inner side of a side support plate.

[0013] A processing method for a scraping-type synthetic leather rolling mechanism includes the following steps: Synthetic leather is conveyed via a conveyor belt in a lifting conveyor mechanism. A rotating pressure roller rolls the upper side of the synthetic leather. When synthetic leather raw material adheres to the rotating pressure roller, the lifting conveyor mechanism is moved downwards, and then a traveling block is driven. The traveling block drives a perforated scraping ring to move from one end of the rotating pressure roller to the other end. Simultaneously, the inner side of the perforated scraping ring moves in contact with the outer side of the rotating pressure roller, thus scraping away the attached waste material from the outer surface of the rotating pressure roller. Finally, the perforated scraping ring drives the abutment sealing sleeve to move and abut against the side of the positioning plate, forming a waste material adsorption cavity with the perforated scraping ring, the abutment sealing sleeve, and the positioning plate. The attached waste material is then drawn into the waste material adsorption cavity. Finally, a suction pump extracts and discharges the attached waste material from the waste material adsorption cavity, thus achieving the scraping and discharge operation.

[0014] The beneficial effects of this invention are as follows:

[0015] When the rotating pressure roller needs to clean the adhesive material on synthetic leather, the invention uses a traveling block to drive a porous scraping ring to move from one end of the rotating pressure roller to the other end. The inner side of the porous scraping ring moves against the outer side of the rotating pressure roller, scraping off the adhesive waste material on the outer surface of the rotating pressure roller. The porous scraping ring drives the abutting sealing sleeve to move and abut against the side of the positioning plate, so that the porous scraping ring, the abutting sealing sleeve, and the positioning plate form a waste adsorption cavity. Then, the adsorbed waste material in the waste adsorption cavity is extracted and discharged by a suction pump, realizing a convenient and efficient cleaning operation. Attached Figure Description
