Description

Technical Field

[0001] This utility model relates to the field of textile production equipment technology, and more specifically to a cleaning and collecting device for a spinning machine blower. Background Technology

[0002] With the continuous improvement of automation in textile equipment, reducing labor intensity and increasing production efficiency have become the core objectives of textile enterprises in optimizing management. In the spinning process, circulating blowing and suction devices, as auxiliary cleaning equipment, have been widely used in processes such as roving, spinning, and winding. They can automatically collect impurities such as accumulated cotton and fallen cotton on the machine, reducing the need for manual cleaning and significantly reducing the workload of machine operators and cleaners.

[0003] However, existing blowing and suction devices generally use small-capacity cotton storage boxes configured as a single unit, which has the following key problems:

[0004] 1. Capacity Limitations and Frequent Cleaning: The capacity of a single cotton storage box is limited. When cotton accumulates to a certain extent, manual cleaning of each machine is required, which is frequent and inefficient. If cleaning is not timely, it can easily lead to a drop in negative pressure in the pipeline, affecting the cleaning effect and even causing pipeline blockage, threatening the workshop environment and yarn quality.

[0005] 2. Insufficient system stability: The design of the single-machine cotton storage box lacks an automatic transfer mechanism. Manual intervention can easily cause production process interruption. Furthermore, when multiple machines operate in parallel, it can easily cause a diversion effect on the negative pressure of the pipeline, affecting the conveying efficiency of the cotton at the far end.

[0006] 3. High maintenance costs: Traditional equipment often has right-angle or obtuse-angle pipe connections, which can easily cause the pipes to get stuck and obstructed at bends, requiring additional manual handling and increasing maintenance costs.

[0007] To address the aforementioned shortcomings, there is an urgent need for a large-capacity, automated flower collection and cleaning device to achieve automatic transfer and centralized storage of flowers at the foot of the ground, reduce manual intervention, and optimize pipeline design to improve system stability and cleaning efficiency. Utility Model Content

[0008] Therefore, the purpose of this utility model is to propose a cotton cleaning and collection device for a spinning machine blower, which solves the shortcomings of the existing single-machine cotton storage box.

[0009] The present invention relates to a cleaning and collecting device for a spinning machine blower, comprising:

[0010] The first cotton storage box is divided into an upper movable box and a lower fixed box by a filter plate. The top of the movable box is the feed inlet.

[0011] The second cotton storage box is connected to the movable box through a sealed corridor, and has a discharge port on its side wall.

[0012] The cotton accumulation gap treatment mechanism includes a cleaning part that is close to the top surface of the filter plate, and a push-pull part that pushes the cleaning part to move back and forth along the filter plate toward the sealed corridor and the second cotton storage box, so as to push the accumulated cotton on the surface of the filter plate into the second cotton storage box.

[0013] The first fan is installed at the feed inlet.

[0014] According to the collection device of this utility model, the fixed box has a perforated plate arranged perpendicularly to the filter plate in the middle, and has a hole on one side connected to the second fan, and is connected to the workshop dust collection system through the second fan and the fixed box pipe.

[0015] According to the collection device of this utility model, the back of the filter plate has a plurality of support bars, which are supported on the mounting position of the first cotton storage box relative to the filter plate; the filter plate is a mesh plate with a mesh count of 30-60.

[0016] According to the collection device of this utility model, the length of the sealed corridor is 5-10cm; the volume of the movable box is 5-10 times the volume of the fixed box.

[0017] According to the collection device of this utility model, the second cotton storage box has an openable and closable seal at the slot corresponding to the sealed corridor.

[0018] According to the collection device of this utility model, the cleaning part is a plastic scraper, the scraping width of which is the same as the width of the filter plate, and the thickness is 1-3cm; the front end of the plastic scraper at its maximum working surface can reach the groove opening of the second cotton storage box.

[0019] According to the collection device of this utility model, a horizontal insert plate is provided in the middle of the second cotton storage box, and an organic glass damper is installed at the discharge port.

[0020] According to the collecting device of this utility model, the push-pull part includes:

[0021] A push-pull rod passes through the hatch and is hinged to the cleaning unit;

[0022] An eccentric wheel motion assembly is connected to the outside of the housing and to the push-pull rod;

[0023] The motor intermittently drives the eccentric wheel motion assembly, causing the push-pull rod to reciprocate.

[0024] According to the collection device of this utility model, it further includes a main cotton conveying pipe located at the front end of the feed inlet and connected to the first blower. The main cotton conveying pipe is connected to multiple branch cotton conveying pipes, and each branch cotton conveying pipe is connected to multiple branch cotton inlet pipes. The pipe diameters of the branch cotton inlet pipes, branch cotton conveying pipes, and main cotton conveying pipes satisfy: d1 < d2 < d3, and their pipe connections are all made using oblique bends with a connection angle of 30°-45°. Each branch cotton inlet pipe is connected to a temporary cotton storage box of a single blower.

[0025] According to the collection device of this utility model, the inclined bend between the cotton distribution pipe and the main cotton distribution pipe is a connecting pipe, and each of the connecting pipes is equipped with an electromagnetic clutch-type regulating valve connected to the controller.

[0026] As can be seen from the above technical solution, compared with the prior art, this utility model has the following technical effects:

[0027] 1. This utility model overcomes the shortcomings of existing single-machine cotton storage boxes by realizing centralized suction and storage, gap cleaning and automatic collection; the device has a simple structure and is easy to operate, which greatly reduces the workload of workers and improves production efficiency.

[0028] 2. Specifically, the filter plate separates lint and dust from the ground surface. A mesh size of 30-60 ensures effective trapping of lint, while allowing dust to enter the fixed box and be drawn away by the second fan to the workshop dust collection system, preventing pollution of the workshop environment. The plastic scraper of the lint-collecting mechanism, driven by a push-pull rod, periodically scrapes away lint from the filter plate surface, automatically transferring it to the second cotton storage box via a sealed corridor, reducing the frequency of manual cleaning.

[0029] 3. The volume of the movable box is 5-10 times that of the fixed box. Combined with the large-capacity design of the second cotton storage box, it significantly extends the cleaning cycle and reduces the need for manual intervention. The sealing of the enclosed corridor automatically closes after the cotton is pushed, and together with the insert plate of the second cotton storage box and the plexiglass damper, it isolates external airflow interference and maintains the system's negative pressure stability.

[0030] 4. The diameters of the feed cotton pipe (d1), the distribution cotton pipe (d2), and the main cotton conveying pipe (d3) increase progressively (d1 < d2 < d3). This, combined with a 30°–45° inclined bend connection design, reduces the risk of cotton clogging at the base and ensures efficient conveying of accumulated cotton to the remote machine. The controller uses multiple electromagnetic clutch-type regulating valves to control the opening and closing of the distribution cotton pipes, preventing negative pressure diversion caused by multiple pipes operating simultaneously and improving system reliability.

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0039] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] Because existing blowing and suction devices generally use small-capacity cotton storage boxes configured on a single unit, there are capacity limitations, frequent cleaning is required, and the system stability is insufficient, which affects the conveying efficiency of the cotton at the far end; the maintenance cost is high, and the pipe connections are mostly right angles or obtuse angles, and the cotton at the far end is prone to getting stuck and obstructed at the bends of the pipes, requiring additional manual handling and increasing maintenance costs.

[0041] Therefore, the technical solution provided by this utility model is a cleaning and collecting device for a spinning machine blower and suction fan, which can be used in the fine spinning process, as well as in the roving process and the scenario of a self-winding suction device.

[0042] See appendix Figure 2 and 3 It includes: a first cotton storage box 1, a second cotton storage box 2, a cotton accumulation gap treatment mechanism 4, and a first fan 51, etc.

[0043] Specifically, the first cotton storage box 1 is divided into an upper movable box 412 and a lower fixed box 411 by a filter plate 41, with the top of the movable box 412 serving as the feed inlet; the second cotton storage box 2 is connected to the movable box 412 via a sealed corridor 3, and has a discharge outlet on its side wall; the cotton accumulation gap treatment mechanism 4 includes a cleaning part that is close to the top surface of the filter plate 41, and a push-pull part that pushes the cleaning part to move back and forth along the filter plate 41 toward the sealed corridor 3 and the second cotton storage box 2, pushing the accumulated cotton on the surface of the filter plate 41 into the second cotton storage box 2; the first fan 51 is installed at the feed inlet.

[0044] Therefore, this utility model, through the structural cooperation between the filter plate and the push-pull rod in the cotton storage box, can periodically clean the cotton fibers that have been filtered and accumulated on the filter plate in the first cotton storage box into the second cotton storage box. This effectively avoids the situation where excessive cotton accumulation on the mesh plate in the first cotton storage chamber leads to low negative pressure in the front pipe, preventing the cotton flow in the pipe from being sucked up, thus avoiding pipe blockage and improving the efficiency of cotton fiber suction and conveying. The accumulated cotton fibers can then be removed at the discharge port, reducing the frequency of manual cleaning.

[0045] Advantageously, in this invention, the fixed box 411 has a perforated plate arranged perpendicularly to the filter plate 41 in the middle, and has a hole on one side for connecting to the second fan 52, and is connected to the workshop dust collection system via the second fan 52 and the fixed box pipe 13. The filter plate 41 is a mesh plate with a mesh count of 30-60; the filter plate separates dust from the floor debris, and the mesh count of 30-60 ensures effective interception of floor debris, while allowing dust to enter the fixed box and be drawn away by the second fan to the workshop dust collection system, thus avoiding pollution of the workshop environment.

[0046] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0047] Even more advantageous, see appendix Figure 3 In this embodiment of the present invention, the back of the filter plate 41 has a plurality of support bars 43, which are supported on the mounting position of the first cotton storage box 1 relative to the filter plate 41; this increases the support strength of the filter plate 41 and avoids damage to the filter plate under large negative pressure.

[0048] In a specific embodiment of this utility model, the length of the enclosed corridor 3 is 5-10cm; the volume of the movable box 412 is 5-10 times the volume of the fixed box 411.

[0049] Advantageously, based on the above embodiments, the second cotton storage box 2 has an openable and closable seal 22 at the slot 21 of the sealed corridor 3; the flexible seal 22 opens when pushing the cotton and closes under negative pressure when returning, and the seal closes the slot of the sealed corridor in time under the action of negative pressure airflow in the first cotton storage box to prevent the bottom cotton in the second cotton storage box from flowing back.

[0050] In this embodiment of the invention, the cleaning part is a plastic scraper 422, the scraping width of which is the same as the width of the filter plate 41, and the thickness is 1-3cm; the front end of the plastic scraper 422 at its maximum working surface can reach the through slot 21 of the second cotton storage box 2. The bottom of the plastic scraper 422 is parallel and in close contact with the filter plate.

[0051] See appendix Figure 2 The second cotton storage box 2 has a horizontally arranged insert plate 23 in the middle, and an organic glass damper 24 is installed at the discharge port. A damper is also opened at the lower part of the insert plate to facilitate the opening of the damper to clean the interference of external airflow on the system when cleaning the ground cotton.

[0052] The push-pull part 42 described in the embodiment of this utility model includes: a push-pull rod 421, an eccentric wheel motion assembly 423, and a motor 424. During cleaning, the insert plate 23 is closed, and the damper 24 is opened to remove accumulated debris, preventing airflow backflow from affecting the system's negative pressure.

[0053] The push-pull rod 421 passes through the movable box 412 and is hinged to the cleaning section; the eccentric wheel motion assembly 423 is connected to the outside of the movable box 412 and to the push-pull rod 421; the motor 424 intermittently drives the eccentric wheel motion assembly 423 to move the push-pull rod 421 back and forth. The motor 424 can be started once every 30 minutes, and the plastic scraper 422 pushes the accumulated cotton into the sealed corridor 3, and finally into the second cotton storage box 2. The motor in this invention can be controlled by a controller to control the opening and closing interval.

[0054] The eccentric wheel motion assembly 423 may include: an eccentric wheel, a connecting rod, a slider, a bearing housing, and an electromagnetic clutch, etc. The eccentric wheel, a disc whose center is offset from the center of rotation, is used to convert the rotational motion of the motor into reciprocating linear motion. The connecting rod connects the eccentric wheel and the push-pull rod, transmitting the eccentric wheel's circular motion into the push-pull rod's linear motion. The slider restricts the movement trajectory of the connecting rod or push-pull rod, ensuring linear motion accuracy. The bearing housing fixes the eccentric wheel shaft, supports the eccentric wheel's rotation, and reduces friction. An electromagnetic clutch may be included, which works with the motor to achieve intermittent start-stop control, avoiding wear and tear from frequent motor starts and stops.

[0055] Based on the above embodiments, see Appendix Figure 1 , 4 6, also includes a main cotton conveying pipe 7 located at the front end of the feed inlet and connected to the first fan 51, the main cotton conveying pipe 7 is connected to multiple branch cotton conveying pipes 6, each branch cotton conveying pipe 6 is connected to multiple branch cotton inlet pipes 8; the pipe diameters of the branch cotton inlet pipes 8, the branch cotton conveying pipes 6 and the main cotton conveying pipe 7 satisfy: d1 < d2 < d3, so as to ensure that the negative pressure between the pipes is progressively increased, maintaining the conveying of the furthest ground cotton.

[0056] For example, the main cotton conveying pipe 7 connects to four branch cotton conveying pipes 6, each branch corresponding to eight sub-infeed cotton pipes 8. The ends of the sub-infeed cotton pipes 8 connect to the temporary cotton storage boxes 9 of the single-unit blower / suction fan. The sub-infeed cotton pipes have a d1=10cm diameter, the branch cotton conveying pipes have a d2=15cm diameter, and the main cotton conveying pipe has a d3=20cm diameter. The pipes are connected using 40° angled bends to reduce cotton snagging. The division of the pipelines into large and small groups ensures that a pipeline failure will not affect the operation of the entire system.

[0057] The cotton inlet pipe and the cotton distribution pipe, as well as the cotton distribution pipe and the main cotton distribution pipe, are connected by inclined bend pipes with a connection angle of 30°-45°, to avoid the cotton flowers getting stuck and obstructed when traveling in the pipes.

[0058] Each of the aforementioned cotton inlet pipes 8 is connected to a temporary cotton storage box 9 for a single-unit blower / suction fan.

[0059] See appendix Figure 5The oblique bend between the cotton distribution pipe 6 and the main cotton distribution pipe 7 is a connecting pipe 10, and an electromagnetic clutch regulating valve 11 is provided on the connecting pipe 10; the electromagnetic clutch regulating valve 11 includes a valve 111, a connecting rod assembly 112 and an electromagnetic clutch component 113; the electromagnetic clutch component 113 is electrically connected to the controller.

[0060] The cotton feeding actions of the distribution and branch cotton feeding pipes are controlled in groups by regulating valves to avoid simultaneous operation that would divert negative pressure across the entire pipeline. The regulating valves can be controlled by the controller to open and close the pipelines in groups, ensuring that only 1-2 groups of pipelines operate at a time, thus maintaining a balanced negative pressure.

[0061] In addition, air vents can be installed near each pipe connection point to facilitate handling when there are blockages at pipe bends.

[0062] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0063] The working stages of this utility model include the following stages:

[0064] Accumulated cotton collection stage: A single blower sucks the accumulated cotton from the ground into the temporary cotton storage box 9, and then transports it to the first cotton storage box 1 via the branch cotton inlet pipe 8 → distribution cotton pipe 6 → main cotton pipe 7. The accumulated cotton adheres to the surface of the mesh plate 41, and the dust passes through the mesh into the fixed box 411 and is extracted by the second blower 52.

[0065] During the cotton accumulation and transfer stage: Motor 424 starts at a set time, and push-pull rod 421 drives plastic scraper 422 to push the accumulated cotton into the second cotton storage box 2. The cover 22 automatically closes after pushing the cotton to prevent airflow backflow.

[0066] Cleaning and maintenance phase: After the second cotton storage box 2 is full, close the insert plate 23, open the air damper 24 for manual cleaning, and the machine does not need to be stopped throughout the process.

[0067] This invention automatically collects and stores the cotton waste collected by the spinning machine's suction and blowing device in a large capacity, reducing the workload of frequent manual removal of waste waste. Simultaneously, it stabilizes the cleanliness of the spinning workshop, ultimately ensuring yarn quality. By adding a cotton-collecting fan to alter the airflow in the pipes, the flow direction of the cotton waste is controlled; thus, automatic collection and centralized storage of the cotton waste are achieved. This reduces worker workload and improves work efficiency while ensuring yarn quality; it also features a simple structure and is easy to use; the cotton waste collection device, using a spinning machine's suction and blowing fan, effectively collects the cotton waste.
