Description

Technical Field

[0001] This utility model relates to the field of textile finishing machinery technology, specifically a centralized lint removal device for a continuous pellet mill. Background Technology

[0002] Fleece fabric is soft and lightweight, a common type of warm fabric that remains warm even when damp. Fleece production typically involves weaving, fabric processing (dyeing, dehydration, drying, etc.), slitting, brushing, combing, shearing, fleece rolling, and finishing. Fleece rolling usually occurs after the shearing process. At this stage, some loose fibers remain on the surface and inside the fabric. During the fleece rolling process, the fabric is agitated and rubbed by the air, causing the loose fibers to fall off automatically. A continuous fleece rolling machine typically includes a housing, a fleece drum, a hot air circulation mechanism, and a humidification mechanism. Some of the fallen fibers fall through the mesh on the fleece drum to the bottom, while the rest enters the hot air circulation system under the action of a fan. To prevent waste fibers generated during fleece rolling from entering the hot air circulation system and causing radiator blockage and reduced heating efficiency, a filter or filtration device is usually installed at the air inlet of the circulating fan.

[0003] Waste lint will adhere to the filter screen. To prevent the filter screen from clogging and affecting hot air circulation and heating, the waste lint needs to be cleaned regularly. In addition, waste lint at the bottom of the equipment also needs to be cleaned regularly to prevent waste lint accumulation.

[0004] The current cleaning methods mostly involve manual cleaning before or after shifts, which is time-consuming, labor-intensive, and not environmentally friendly. Therefore, it is necessary to technically upgrade the current equipment to meet the usage requirements. Utility Model Content

[0029] Example 1, referring to Figure 1-4 A continuous granulator centralized dehairing device includes a housing 1 with a granulator drum inside. The granulator drum 2 is generally installed in the housing 1 by a support wheel 3. This is existing technology, so its specific structure and operating principle will not be described in detail here. The housing 1 has the following features:

[0030] The hair removal assembly includes an inclined mounting plate 4, which is formed into a roughly square plate structure. The angle between the inclined mounting plate 4 and the horizontal direction is 5° to 15°, and the degree can be selected according to the usage requirements. It is installed on the inner wall of the housing 1 and located directly below the shaking cylinder. A bottom support 5 is also fixedly installed on the inner wall of the housing 1 to support the bottom surface of the inclined mounting plate 4. The bottom support 5 is formed into a roughly triangular plate structure. A scraper device I8 is provided above the inclined mounting plate 4 to scrape the hair deposited on the inclined mounting plate 4. The inclined mounting plate 4 is formed into a roughly square plate structure. A dust removal pipe 6 is installed at one end of the inclined mounting plate 4 near the bottom of the housing 1 to facilitate the discharge of scraped hair. The outlet end of the dust removal pipe 6 extends outside the housing 1. A pneumatic damper I7 is installed at the outlet end of the dust removal pipe 6.

[0031] The number of scrapers in scraper device I8 and scraper device II15 is at least 2-4 pieces, and the scrapers in scraper device I8 and scraper device II15 are made of nylon or polytetrafluoroethylene.

[0032] The aforementioned scraper device I8 and scraper device II15 can be composed of a scraper chain and a scraper. The scraper chain is driven by an external power shaft, thereby driving the scraper on the scraper chain to move in a straight line, so as to scrape the lint on the inclined mounting plate 4.

[0033] The heat circulation assembly includes a fan 10 installed on the top of the housing 1, a heat exchanger 12 for heating the airflow installed on the outer wall of the air outlet of the fan 10, the heat exchanger 12 can heat the air outlet of the fan 10 through an external heat source, thereby heating the airflow in the air outlet and forming hot air, a duct I 11 connected to the top of the housing 1 is installed at the air outlet of the fan 10, a duct II 13 is installed at the air inlet of the fan 10, the duct I 11 and the duct II 13 are tubular structures, an air outlet pipe 17 is installed at the other end of the duct II 13, and a pneumatic damper II 18 is installed at the outlet end of the air outlet pipe 17.

[0034] Pneumatic damper I7 and pneumatic damper II18 can be opened or closed simultaneously.

[0035] A filter screen 14 is also installed on the inner wall of the air duct II13. The angle between the filter screen 14 and the horizontal direction is 45°~75°. The specific angle can be selected according to the usage requirements. A scraper device II15 for scraping the surface of the filter screen 14 is installed on the inner wall of the air duct II13 below the filter screen 14.

[0036] A switch door 16 is installed on the outer wall of the air duct II 13 to facilitate cleaning of the inside of the air duct II 13. When it is necessary to clean the inside of the air duct II 13, the switch door 16 can be opened for cleaning.

[0037] Example 2, the continuous granulator centralized dehairing device described in Example 1, wherein the bottom of the inclined mounting plate 4 is formed with a plurality of spaced U-shaped grooves, the bottom end of the U-shaped grooves has an opening, the opening is vertically downward and formed into a trumpet shape, the dust removal pipe 6 is located below the inclined mounting plate 4, and the opening is connected to the interior of the dust removal pipe 6.

[0038] The continuous granulator centralized dehairing device in Examples 1-2 operates on the following principle:

[0039] During the operation of the granulator, the generated fluff will fall onto the inclined mounting plate 4. At this time, scraper device I8, scraper device II15, pneumatic damper I7 and pneumatic damper II18 are activated in sequence. Scraper device I8 and scraper device II15 scrape the fluff on the inclined mounting plate 4 to ensure that the fluff does not accumulate on the inclined mounting plate 4. The scraper is made of nylon plate or polytetrafluoroethylene plate. These materials are wear-resistant and do not easily damage the fluff. The scraped fluff is discharged through the dust removal pipe 6 at the lower end of the inclined mounting plate 4. The outlet end of the dust removal pipe 6 extends to the outside of the box 1.

[0040] During lint removal, the fan 10 delivers hot air into the housing 1 through the duct I 11. At the same time, fresh air from outside enters the housing 1 through the duct II 13, forming a fresh air circulation. To prevent external impurities from entering the housing 1, a filter screen 14 is installed on the inner wall of the duct II 13 to filter dust and fine lint from the air. When too much dust and lint accumulate on the surface of the filter screen 14, the scraper device II 15 can scrape the surface of the filter screen 14 to ensure that the filter screen 14 is unobstructed. In addition, a door 16 is installed on the outer wall of the duct II 13 to facilitate regular cleaning of the inside of the duct II 13.

[0041] In addition, components such as the inclined mounting plate 4, dust removal pipe 6, filter screen 14, and air duct II 13 can be inspected and cleaned regularly to ensure the normal operation of the equipment and the hair removal effect.
