Description

Technical Field

[0001] This utility model relates to the field of textile machinery cleaning equipment technology, and in particular to a flexible suction port for a roving blowing and suction cleaning machine. Background Technology

[0002] The roving blower / suction cleaner is a key piece of equipment in textile machinery used to remove fly ash from inside the drafting sheet. It maintains cleanliness through negative pressure absorption, preventing fly ash buildup from affecting production quality. In existing technology, the suction inlet of the cleaner is typically designed at a fixed height, positioned close to the drafting sheet surface to absorb fly ash. However, this design has the following significant problems in practical applications:

[0003] Unable to adapt to deformation and misalignment of the drawing cover plate:

[0004] Roving frames are typically assembled from multiple sections of equipment. Initially, all components are aligned, but with prolonged operation, the drafting plates are frequently raised or lowered, leading to height differences or misalignment between adjacent plates. Traditional suction inlets, due to their fixed height, cannot dynamically adjust their position to accommodate drafting plate deformation, resulting in inconsistent distances between the inlets and the plates. This significantly reduces fly waste absorption efficiency; excessive distance leads to insufficient negative pressure, while frequent contact between the inlets and drafting plates exacerbates mechanical wear.

[0005] Manual adjustment is inefficient.

[0006] To alleviate the above problems, some technical solutions employ manual adjustment of the suction inlet height, such as fixing the suction inlet position with bolts or adding shims to compensate for height differences. However, such methods require frequent machine shutdowns, which not only increases maintenance costs but also makes it difficult to adapt to dynamically changing drawing cover heights in real time, making them extremely unsuitable, especially in continuous production scenarios.

[0007] Structural defects of existing improvement solutions:

[0008] The few solutions that attempt to automatically adjust the suction nozzle height through mechanical structures have the following limitations:

[0009] Rigid adjustment mechanism: For example, using springs or hydraulic devices to control the position of the suction port, but its response speed is slow, and its complex structure is easily affected by fly debris or oil stains, resulting in a high failure rate;

[0010] Limited adjustment range: The design relying on fixed slide rails or limit blocks cannot cover the maximum deformation that the stretch cover may undergo, which may cause the suction port to still be out of the effective working range;

[0011] Lack of pressure adaptability: The contact pressure between the suction port and the stretching cover cannot be dynamically adjusted according to the flatness of the stretching cover. Insufficient pressure can easily cause the rollers to lose contact, or excessive pressure can accelerate the wear of components.

[0012] In summary, the existing suction port design of roving blow-suction cleaning machines is insufficient to effectively address the issues of reduced cleaning efficiency and equipment wear caused by deformation and misalignment of the drafting cover. There is an urgent need for a flexible suction port device with a simple structure, a wide adjustment range, and the ability to automatically maintain a constant distance between the suction port and the drafting cover, in order to improve cleaning performance and reduce maintenance costs. Utility Model Content

[0013] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a flexible suction port for a roving blowing and suction cleaning machine.

[0014] To achieve the above objectives, the innovative features of this utility model are as follows: its structure includes:

[0015] The suction assembly is used to create negative pressure to absorb fly ash;

[0016] The suction port, connected to the suction assembly, is used to approach the stretch cover to clean its interior;

[0017] An adaptive adjustment mechanism, including a roller assembly and a slide rail assembly;

[0018] The adaptive adjustment mechanism contacts the surface of the stretch cover plate through rollers and drives the suction port to move vertically along the slide rail assembly based on the height change of the stretch cover plate, so that the suction port and the stretch cover plate always maintain a constant distance, thereby ensuring the cleaning effect.

[0019] Furthermore, the aforementioned slide rail assembly includes:

[0020] Linear guide rail, fixed to the suction assembly, is installed in a direction perpendicular to the expected movement trajectory of the stretching cover plate;

[0021] A slider is slidably mounted on a linear guide rail;

[0022] Suction nozzle connector, used to fix the slider;

[0023] The roller assembly includes a roller bracket and at least two rollers. The rollers are mounted on the roller bracket, and the suction port is fixed to the roller bracket via a suction port connector. The relative position of the suction port and the rollers is fixed.

[0024] Furthermore, the roller bracket is a fixed plate with two symmetrical ear plates at its bottom. The two rollers are rotatably mounted on the ear plates via a rotating shaft. The fixed plate has two parallel strip grooves at its center. The suction port connector is a U-shaped block with a flat back. The slider is fixed inside the opening of the U-shaped block. The suction port connector is fixed to the strip groove by bolts passing through the back of the U-shaped block. The position of the adjusting bolts in the strip groove is used to adjust the installation height of the roller bracket.

[0025] Furthermore, the U-shaped block has an arc-shaped plate at its open end, and a first clamp is provided on the arc-shaped plate. The inner diameter of the arc-shaped plate, the inner diameter of the first clamp, and the outer diameter of the suction port are matched, and the arc-shaped plate and the suction port are fixed together by the first clamp.

[0026] Furthermore, the aforementioned adaptive adjustment mechanism also includes weights. The top of the fixed plate is symmetrically provided with two fixing holes. The weights are cuboid structures with a connecting hole in the center. Several weights are vertically stacked and fixed to the top of the fixed plate by fastening bolts passing through the fixing holes and connecting holes.

[0027] Furthermore, the weight of each of the aforementioned weights is between 0.1 kg and 0.3 kg, and the number of weights is increased or decreased according to the flatness of the drawing cover plate to dynamically adjust the bonding pressure of the rollers on the drawing cover plate.

[0028] Furthermore, the constant distance is adjusted with millimeter-level precision by adjusting the position of the bolt in the slot.

[0029] Furthermore, the suction assembly includes a suction vertical pipe and a retractable corrugated pipe. The suction port is connected to the bottom of the suction vertical pipe through the corrugated pipe. The top of the linear slide rail is provided with an arc-shaped fixing plate. The arc-shaped fixing plate is provided with a second clamp. The inner diameter of the second clamp and the inner diameter of the arc-shaped fixing plate are both matched with the outer diameter of the suction vertical pipe. The arc-shaped fixing plate and the suction vertical pipe are fixed together by the second clamp.

[0030] The beneficial effects of this utility model are:

[0031] Constant distance maintenance: The rollers drive the vertical displacement of the suction port as the height of the drawing cover changes, ensuring that the distance between the suction port and the drawing cover remains constant.

[0032] Adaptive adjustment: The number of weights and the position of the slots are adjustable to adapt to different working conditions. Attached Figure Description
