Technical Field

[0001] This utility model belongs to the field of felt scrap recycling equipment, specifically an HMP3 felt scrap recycling equipment. Background Technology

[0002] The HMP3 felt scrap recycling equipment is a mechanical device specifically designed for recycling and processing scraps generated during the felt production process. It can reprocess waste scraps into reusable felt raw materials, achieving resource recycling, reducing production costs, and minimizing environmental pollution.

[0003] For example, announcement number CN220942500U describes a felt scrap recycling device, relating to the field of recycling devices. It includes a machine body with a feed inlet at the top and a label indicating "felt scrap recycling device" on one side of the top. A control panel is located in the middle of one side of the top. A grinding assembly is located on one side of the machine body. A feeding plate, which mates with the bottom of the crushing assembly, is located on the top of the inner wall of the machine body. A discharge chute is located on one side of the feeding plate. A transmission assembly, which mates with the interior of the machine body, is located at the bottom of the discharge chute. A second support plate, which mates with the interior of the machine body, is located at the bottom of the transmission assembly. A pressing assembly, which mates with the bottom of the inner part of the machine body, is located at the bottom of the second support plate. A vacuum cleaner is located on the other side of the machine body. This felt scrap recycling device, under the action of the pressing assembly, compresses felt fragments into blocks or flakes through compression, facilitating subsequent transportation and processing.

[0004] Most HMP3 felt scrap recycling equipment on the market lacks a dedicated pre-treatment device, which makes it impossible to remove impurities such as fluff and dust mixed in with the felt scrap in advance. This leads to incomplete sorting and easy fiber clumping, ultimately reducing the utilization rate of the finished product. Utility Model Content

[0005] The purpose of this invention is to provide an HMP3 felt scrap recycling device to solve the above problems, which can pre-treat HMP3 felt scrap.

[0006] This utility model achieves the above objectives through the following technical solution: an HMP3 felt scrap recycling device, comprising a felt scrap recycling device body, a U-shaped mounting plate, a guide plate, a silicone coated roller, and a dust collection component;

[0007] A PLC control panel is fixedly installed at one end of the main body of the felt scrap recycling equipment, and a feed inlet is opened at the upper end of the main body of the felt scrap recycling equipment.

Dust conveying pipes with solenoid valves on the outside are fixedly installed at both ends of one side of the dust collection box. One end of the dust conveying pipe is connected to the first dust collection hood and the second dust collection hood.

[0015] A centrifugal fan is fixedly installed at one end of the main body of the felt scrap recycling equipment. An air conveying pipe is fixedly installed at the air inlet end of the centrifugal fan, and one end of the air conveying pipe is connected to the dust collection box.

[0016] Preferably, in order to prevent impurities from adhering to the guide plate, the outer side of the guide plate is coated with an inorganic nano-silicon antistatic coating.

[0017] Preferably, in order to enable the silicone coating roller to rotate, servo motors are fixedly installed on both sides of one end of the felt scrap recycling equipment body, and the output end of the servo motor is fixedly connected to the silicone coating roller through a rotating shaft.

[0031] The embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0032] Please see Figures 1-6 As shown, an HMP3 felt scrap recycling device includes a felt scrap recycling device body 1, a U-shaped mounting plate 2, a guide plate 3, a silicone coated roller 4, and a dust collection component 5.

[0033] A PLC control panel 6 is fixedly installed at one end of the main body 1 of the felt scrap recycling equipment, and a feed inlet is opened at the upper end of the main body 1 of the felt scrap recycling equipment.

[0034] The U-shaped mounting plate 2 is fixedly installed at the upper end of the feed inlet;

[0035] The guide plate 3 is symmetrically installed on the inner side of the U-shaped mounting plate 2. A square hole 7 is opened at one end of the guide plate 3. The outer side of the guide plate 3 is coated with an inorganic nano-silicon antistatic coating.

[0036] The silicone coating roller 4 is rotatably installed on both ends of the inner side of the U-shaped mounting plate 2. The servo motor 8 is fixedly installed on both sides of one end of the felt scrap recycling equipment body 1. The output end of the servo motor 8 is fixedly connected to the silicone coating roller 4 through the rotating shaft. The servo motor 8 is electrically connected to the PLC control panel 6. During use, the spacing between the silicone coating rollers 4 is preset according to actual requirements.

[0037] like Figure 3 and Figure 4 As shown, the vacuuming assembly 5 includes:

[0038] The first dust cover 501 is fixedly installed in the square hole 7. A filter screen 9 is detachably installed on one end of the first dust cover 501 through a positioning screw.

[0039] The second dust hood 502 is fixedly installed on both ends of the inner side of the U-shaped mounting plate 2. A U-shaped scraper 503 is detachably installed on one end of the second dust hood 502 through a positioning screw. One end of the U-shaped scraper 503 is in contact with the silicone coating roller 4. The U-shaped scraper 503 is made of polyurethane elastomer. During use, the U-shaped scraper 503 should be replaced regularly according to the actual situation.

[0040] The dust collection box 504 is fixedly installed on both sides of the U-shaped mounting plate 2. Dust collection pipes 505 with solenoid valves on the outside are fixedly installed at both ends of one side of the dust collection box 504. One end of the dust collection pipe 505 is connected to the first dust collection hood 501 and the second dust collection hood 502. A HEPA filter is inserted into one end of the dust collection box 504. A silicone sealing ring is provided at the connection between the dust collection box 504 and the HEPA filter to provide a seal. At the branch points of the dust collection pipe 505 and the first dust collection hood 501 and the second dust collection hood 502, an electric regulating valve is provided, which is electrically connected to the PLC control panel 6 to adjust the negative pressure intensity of each branch. This is an existing mature technology.

[0041] Centrifugal fan 506 is fixedly installed at one end of the felt scrap recycling equipment body 1. An air inlet pipe 507 is fixedly installed on the air inlet of centrifugal fan 506, and one end of the air inlet pipe 507 is connected to the dust collection box 504. Centrifugal fan 506 is electrically connected to PLC control panel 6. During operation, a U-shaped scraper 503, made of polyurethane elastomer, is fixed to one end of the second dust hood 502. The scraper blade has rounded corners and remains in close contact with the surface of the silicone coating roller 4. As the silicone coating roller 4 rotates continuously, the U-shaped scraper 503 precisely scrapes away impurities adsorbed on the roller surface, preventing impurities from re-adhering or falling back into the raw material due to roller rotation. Meanwhile, the centrifugal fan 506 continuously operates to generate a stable negative pressure. The negative pressure is transmitted through the air duct 507 to the dust collection boxes 504 on both sides of the U-shaped mounting plate 2, and then through the dust conveying pipe 505 to act on the first dust collection hood 501 and the second dust collection hood 502 respectively. The second dust collection hood 502 corresponds to the scraping area of ​​the U-shaped scraper 503, forming a local strong airflow, which sucks the scraped impurities into the hood in real time to prevent the impurities from scattering. The first dust collection hood 501 is fixed in the square hole 7 of the guide plate 3, aligned with the area above the raw material conveying path, and simultaneously adsorbs the suspended dust raised during the movement of the raw materials, realizing the dual capture of attached impurities and suspended dust, with no dead corners for adsorption.

[0042] Impurities sucked in by the first suction hood 501 and the second suction hood 502 are quickly transported to the dust collection box 504 via the dust conveying pipe 505. One end of the first suction hood 501 passes through the filter screen 9 for preliminary filtration, intercepting large particles such as clumps and lint, thus preventing large impurities from clogging the dust conveying pipe 505. The fine dust after preliminary filtration enters the interior of the dust collection box 504 and undergoes deep filtration through the HEPA filter screen inserted inside the dust collection box 504, ensuring that the exhaust airflow is clean and pollution-free. Operators can periodically disassemble the filter screen 9 and open the dust collection box 504 for cleaning, making maintenance convenient.

[0043] Working Principle: The operator, via the PLC control panel 6 at one end of the felt scrap recycling equipment body 1, presets key operating parameters based on the material, shape, and impurity content of the felt scrap to be processed: The output speed of the servo motor 8 is set to ensure the rotational speed of the silicone coating roller 4 matches the raw material conveying rhythm, guaranteeing impurity capture while avoiding excessive friction damage to the fibers; the negative pressure power of the centrifugal fan 506 is adjusted to stabilize the system negative pressure within a suitable range, meeting the adsorption requirements of impurities of different particle sizes; the linkage start-stop logic of the solenoid valve on the outside of the dust conveying pipe 505 is set to ensure that the solenoid valve opens synchronously after the centrifugal fan 506 starts, forming a closed-loop dust collection path; after the parameters are set, the equipment is started with one button via the PLC control panel 6. The servo motor 8 and centrifugal fan 506 operate synchronously, the solenoid valve automatically opens, and the equipment enters a stable standby state. After the felt scrap is fed into the upper feed port of the U-shaped mounting plate 2, the guide plates symmetrically installed on the inner side of the U-shaped mounting plate 2 immediately play a guiding role. 3. The inclined design, combined with the smooth plate surface, guides the raw materials to move evenly and smoothly along the preset path towards the feed port of the felt scrap recycling equipment body 1, avoiding local accumulation or feed deviation. At the same time, the inorganic nano-silicone antistatic coating on the outer side of the guide plate 3 can reduce surface adsorption force, effectively reducing the adhesion and accumulation of dust and fine lint on the plate surface, ensuring the continuity of raw material conveying. Even with long-term continuous feeding, there will be no jamming problem. The silicone coating roller 4, which is fixedly connected to the servo motor 8 through the rotating shaft, rotates at a preset speed under the drive of the servo motor 8. The two silicone coating rollers 4 rotate in opposite directions. The surface coating of the silicone coating roller 4 is made of flexible silicone material, which has both moderate stickiness and elasticity. When the felt scrap passes through the roller surface, the coating can gently adhere to the surface of the raw material, efficiently capturing the lint, dust and fine sticky impurities attached to the raw material. Moreover, the flexible contact method will not pull or break the felt fibers, ensuring that the fiber integrity of the raw material is not damaged, and preserving a high-quality fiber foundation for subsequent recycling processing.

[0044] The dust collection component 5 enables the pre-separation of lint, dust, and fine sticky impurities from felt scraps, preventing impurities from entering subsequent sorting stages. This solves the problem of incomplete sorting and fiber clumping caused by impurities in existing equipment, effectively reducing the probability of fiber clumping and improving the utilization rate of finished products. After pretreatment, it can remove lint, dust, and fine sticky impurities from felt scraps, making them clean raw materials. The materials smoothly pass through the feed inlet of the felt scrap recycling equipment body 1 and enter the body 1 to complete the core processes of crushing, loosening, sorting, and reforming in sequence, ultimately producing recycled felt raw materials with uniform strength and low impurity content.
