A connector, a screw, a rotating wheel and a cleaning mechanism are fixedly installed on the support plate. The glue blocks on the needle plate are removed by the set wire ring, and the external air is absorbed through the connecting rod and other structures, and the needle plate below is blown through the air outlet duct, so that the small glue blocks on the needle plate that are scraped off by the wire ring are blown away and cleaned, so that the glue blocks on the needle plate can be cleaned more cleanly.

[0003] However, the above patent uses a wire ring to clean the rubber block during use, but most of the steel needles above the needle plate are curved, and the contact area between the wire ring and the needles on the needle plate is limited. There are dead corners when removing the rubber, and long-term use can easily lead to accumulation of rubber blocks, reducing the cleaning effect of the rubber blocks. Utility Model Content

[0035] like Figure 1-5As shown, the needle plate glue removal device of the square carpet pre-coating machine includes a mounting bracket 1 and a mounting cross plate 2, a hydraulic cylinder 11 is installed inside the mounting bracket 1, and the front end of the hydraulic cylinder 11 is connected to a mounting frame 12, a driving motor 13 is installed below the mounting frame 12, and the output end of the driving motor 13 is connected to a lifting screw 14, a slider 15 is installed on the lifting screw 14, the mounting cross plate 2 is installed on the outside of the slider 15, and a driving motor 21 is installed on the top of the mounting cross plate 2, a sleeve 24 is connected below the driving motor 21, and a transmission gear 22 is installed above the sleeve 24 close to the driving motor 21, a synchronous belt 23 is installed above the sleeve 24, and a mounting circle is installed at the bottom of the sleeve 24 The mounting ring 25 is provided with a wire brush 26 at the axis of the mounting ring 25, a wire brush 27 is provided at the bottom of the mounting ring 25, a needle plate body 3 is provided at the bottom of the mounting bracket 1, and a steel needle 31 is provided at the top of the needle plate body 3, a driving motor 13 drives the slider 15 and the mounting cross plate 2 to descend through the lifting screw 14, and a driving motor 21 drives the sleeve 24 to rotate. After the sleeve 24 contacts the steel needle 31, a wire brush 26 at the middle part of the mounting ring 25 cleans the steel needle 31, and a wire brush 27 cleans the contact part between the steel needle 31 and the needle plate body 3. In this way, the needle plate body 3 and the steel needle 31 can be fully and reliably cleaned. The mounting frame 12 and the mounting bracket 1 are connected by a hydraulic cylinder 11. The sliding installation structure is formed, and the hydraulic cylinders 11 are evenly spaced and distributed inside the mounting bracket 1. The mounting frame 12 can be pulled and stored into the mounting bracket 1 by the evenly spaced hydraulic cylinders 11, so that the storage of the device can be facilitated. Light rods are installed on both sides of the slider 15. When the slider 15 moves, the light rods can guide and limit the sliding of the slider 15 and the mounting cross plate 2, so that the descent of the slider 15 and the mounting cross plate 2 is more reliable and stable. A bearing is installed at the connection between the sleeve 24 and the mounting cross plate 2, and the sleeves 24 are driven by a synchronous belt 23. The bearing can reduce the friction when the sleeve 24 rotates, and the sleeves 24 in the same row can be rotated synchronously in the same direction through the synchronous belt 23. The sleeve 24 and the mounting cross plate 2 are connected. The mutually perpendicular setting is adopted, and the mutually perpendicular setting can make the sleeve 24 more convenient to be sleeved on the outside of the steel needle 31; the mounting ring 25 and the sleeve 24 are arranged with an axis coincidence, and the axis coincidence setting can make the mounting ring 25 and the sleeve 24 rotate synchronously, and can also make the rotation of the mounting ring 25 more reliable and stable; the number of the transmission gears 22 is two, and the axis coincidence setting is adopted between the transmission gear 22 and the sleeve 24; the two transmission gears 22 can make the two rows of sleeves 24 rotate in opposite directions, and the axis coincidence setting can make the transmission of the transmission gear 22 to the sleeve 24 more reliable; the mounting cross plate 2 and the mounting bracket 1 are arranged in parallel with each other, and the parallel setting can make the mounting cross plate 2 more reliable and stable with the rise and fall of the slider 15.

[0036] The working principle of the utility model is as follows: when using the device, the device is fixed on the chain rack in the oven. When degumming is required, the hydraulic cylinder 11 pushes the mounting frame 12 to move toward the needle plate body 3. At this time, the driving motor 13 drives the lifting screw 14 to rotate, thereby driving the slider 15 and the mounting cross plate 2 to descend. When the slider 15 moves, the smooth rod can guide and limit the sliding of the slider 15 and the mounting cross plate 2, thereby making the descent of the slider 15 and the mounting cross plate 2 more reliable and stable. During the descent of the mounting cross plate 2, the driving motor 21 drives the sleeve 24 to rotate, and the sleeves 24 are driven by the transmission gear 22 and the synchronous belt 23, thereby making the two rows of sleeves 24 rotate in opposite directions. After contacting the steel needle 31, the wire brush 1 26 in the middle part of the mounting ring 25 cleans the steel needle 31. At this time, the sleeve 24 continues to descend until the wire brush 27 contacts the needle plate body 3. At this time, the sleeve 24 continues to rotate, and the wire brush 27 cleans the contact part between the steel needle 31 and the needle plate body 3. The wire brush 27 rotates in the opposite direction to push the cleaned rubber blocks and impurities from the bottom of the steel needle 31. In this way, the needle plate body 3 and the steel needle 31 can be comprehensively and reliably cleaned. After cleaning, the driving motor 13 drives the mounting cross plate 2 to rise through the slider 15, and the hydraulic cylinder 11 pulls the mounting frame 12 and the mounting cross plate 2 back to the inside of the mounting bracket 1 to complete the storage of the device.
