Description

Technical Field

[0001] This utility model relates to the field of textile machinery auxiliary equipment technology, and in particular to a combined exhaust and dust collection device for a roller napping machine. Background Technology

[0002] Roller napping machines are key equipment in the textile industry for fabric finishing. During the napping process, high-speed rotating rollers pull out a large amount of short fibers, fluff, and dust from the fabric surface, collectively known as "recycled fibers." These recycled fibers must be promptly sucked away and centrally processed by a matching exhaust and dust collection device. If not handled properly, the recycled fibers will permeate the workshop air, not only seriously polluting the working environment and endangering the health of operators, but also potentially adhering to equipment and products, affecting production efficiency and product quality.

[0003] Currently, existing exhaust dust collection devices typically use fans to generate negative pressure, drawing the returned fibers into dust collection boxes or bags through pipes. However, in actual use, these devices still have many shortcomings. First, the high-powered fans, as the core power source, generate enormous aerodynamic noise during operation. Simultaneously, the fan's support structure is often simply designed and lacks stability, leading to strong vibrations during operation. The combined effect of vibration and noise further deteriorates the workshop's working environment. Second, many dust collection devices have relatively simple filtration structures, resulting in low filtration efficiency for fine dust. This causes a large amount of fine fibers to be directly released into the atmosphere with the exhaust gas, causing secondary pollution and failing to meet increasingly stringent environmental protection requirements. Furthermore, dust collection systems accumulate large amounts of flammable fiber dust during operation, but existing devices generally lack necessary safety pressure relief designs, posing certain safety hazards. Additionally, the maintenance access for cleaning and recycling returned fibers is not convenient enough, increasing the difficulty and workload of maintenance.

[0004] Therefore, this utility model proposes a combined exhaust and dust collection device for a roller texturing machine to address the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the prior art of a combined exhaust and dust collection device for a roller brushing machine, such as high exhaust noise, unstable fan support leading to vibration, incomplete dust collection causing secondary pollution, and lack of necessary safety pressure relief measures in the collection system, this utility model aims to provide a combined exhaust and dust collection device for a roller brushing machine with an improved structure that can effectively solve the above problems.

The support frame includes a support block and a triangular bracket; The collection mechanism includes an air outlet sluice fixed to the hair collection chamber and a dust collection bag connected to the air outlet sluice.

[0008] Furthermore, the support frame supports the fan through a combination structure of the support block and the triangular bracket, the silencer is installed on the pipe body of the connecting pipe, and the pressure relief ventilation hole and the safety door are installed on the outer wall of the hair collection chamber.

[0009] Preferably, the fan is supported on the support block, and the triangular bracket is disposed at the bottom of the support block.

[0010] Preferably, a combined exhaust and dust collection device for a roller brushing machine is further provided with a rubber sealing gasket at the connection between the end of the connecting pipe and the return collection chamber.

As a further preferred option, the collection mechanism 2 also includes a collection trough 206, which is an open trough. The collection trough 206 is fixed directly below all the dust collector bags 205 by a bracket to receive and collect residual dust that falls off the dust collector bags 205, making it easy to clean.

[0024] Working principle: The two main units 1 are connected to the blower 4 via a connecting hose 3. The blower 4 sucks out the lint generated by the main unit 1 and then transports it through the connecting pipe 5. A silencer 6 is installed on the outer wall of the connecting pipe 5 to reduce noise. The end of the connecting pipe 5 is connected to the lint collection chamber 8, and the lint is transported into the lint collection chamber 8 through the connecting pipe 5. A rubber sealing gasket 7 is fixedly connected at the connection between the connecting pipe 5 and the lint collection chamber 8 to prevent leakage. A pressure relief ventilation hole 9 and a safety door 10 are installed on the outer wall of the lint collection chamber 8.
