Description

Technical Field

[0001] This utility model relates to a flat rolling device, specifically a flat rolling device for microfiber leather for footwear, and belongs to the field of microfiber leather processing technology for footwear. Background Technology

[0002] Microfiber leather (microfiber synthetic leather) is a high-performance artificial leather widely used in footwear manufacturing due to its texture, excellent physical properties, and environmental friendliness, which are close to genuine leather. In the production of microfiber leather, flat rolling is an important finishing process. It mainly uses mechanical pressure to flatten the leather surface or the entire leather, making the surface fibers more tightly arranged and reflecting light more evenly.

[0003] However, when microfiber leather is subjected to flat rolling, if dust or hard particles (such as grit or hardened adhesive) adhere to the leather surface, these hard particles will be pressed into the leather when it enters the high-pressure roller section, causing pits or scratches on the leather surface and thus affecting the flat rolling effect. Utility Model Content

[0004] The purpose of this invention is to provide a microfiber leather flat rolling device for shoes in order to solve the above problems. When the air knife installed on the support block generates a high-speed airflow, it physically blows the leather, thereby removing dust and hard particles from the surface of the leather. When the ion bar releases positive and negative ion flow, it can neutralize the static electricity on the surface of the leather and prevent dust from being re-adsorbed.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a microfiber leather flat rolling device for footwear, comprising a calender body, an upper roller and a lower roller rotatably mounted on the calender body, a dust removal mechanism fixed on the calender body, the dust removal mechanism comprising a silicone scraper and a mounting frame, the mounting frame fixedly connected to the calender body, the silicone scraper fixedly connected to the mounting frame, the upper roller and the silicone scraper being rotatably connected, a support block fixedly fixed to the top of the mounting frame, an air knife fixedly mounted between two support blocks, an air inlet pipe connected to the air knife, and an ion bar fixedly mounted on the air knife.

[0006] Preferably, the silicone scraper is located on the side wall of the mounting frame near the calender body, and the silicone scraper is arranged with an inclined structure.

[0007] Preferably, a support mechanism is fixed on the calender body. The support mechanism includes a base and a sleeve rod. The base is fixedly installed on the calender body, and the sleeve rod is fixedly connected to the base. A sliding rod is slidably connected to the sleeve rod, and a spreading plate is fixedly installed on the sliding rod. The spreading plate is fixedly connected to the calender body.

[0008] Preferably, the slide bar is located at the center of the bottom end of the material spreading plate, and the part of the sleeve that contacts the slide bar has an arc-shaped structure.

[0009] Preferably, a limiting mechanism is slidably installed on the calender body. The limiting mechanism includes a stop bar and a locking bar. The stop bar is slidably installed on the material spreading plate. The bottom end of the stop bar is fixedly connected to the locking bar. A positioning block is threadedly connected to the locking bar. A connecting rod is fixedly installed between the two locking bars.

[0010] Preferably, the material spreading plate is provided with two sets of sliding grooves symmetrically, and a locking rod is slidably installed in the sliding groove, and the positioning block abuts against the bottom end of the material spreading plate.

[0011] Preferably, the diameter of the clamping rod is equal to the width of the slide groove, the clamping rod is slidably connected to the material spreading plate, and the diameter of the positioning block is greater than the width of the slide groove.

[0012] Preferably, a feeding mechanism is fixed on the calender body. The feeding mechanism includes a bracket and a fixing plate. The bracket is fixedly connected to the calender body, and a fixing plate is fixedly installed between the two brackets. A rotating rod is rotatably connected to the fixing plate.

[0014] Preferably, the plurality of the rotating rods are arranged at equal intervals and the rotating rods are arranged at an angle.

[0015] The beneficial effects of this utility model are as follows: When the leather is conveyed into the calender body, the air knife switch installed on the support block is turned on. The air knife can generate a high-speed airflow through the air inlet pipe installed at the top. The high-speed airflow physically sweeps the surface of the leather, thereby removing dust and hard particles from the surface of the leather. When the ion bar installed on the air knife releases positive and negative ion flow, it can neutralize the static electricity on the surface of the leather, thereby preventing dust from being re-adsorbed and helping to prevent dust from affecting the smoothness of the leather. When the calender body is started, the upper roller performs a smoothing treatment on the leather. The mounting bracket fixed on the calender body has a silicone scraper installed on its side wall. When the upper roller rotates, it comes into contact with the silicone scraper, which can scrape away the impurities on the surface of the upper roller, thereby improving the processing effect of the upper roller.
