Description

Technical Field

[0001] This utility model relates to the technical field of cotton processing equipment, and in particular to a cotton inspection machine that facilitates automatic removal of gray cotton. Background Technology

[0002] In the cotton textile processing, strict quality testing and purification of raw cotton are necessary to ensure the quality of the final yarn and fabric. Cotton testing machines are key equipment for achieving this goal; one of their core functions is to identify and remove inferior cotton mixed in with the raw cotton, such as impurities like gray cotton formed due to improper growth or storage.

[0003] Currently, cotton inspection machines generally adopt pneumatic rejection, which means that after the gray cotton is identified by sensors or vision systems, the control system drives high-pressure airflow to precisely blow away the gray cotton at specific nodes in the cotton conveying path, causing it to deviate from the main material flow and be rejected. This non-contact rejection method is highly efficient and is the mainstream technical solution in the industry.

[0004] However, in actual production applications, the pneumatic rejection components on existing cotton inspection machines have common shortcomings in structural design. On the one hand, the pipes and nozzles used for jetting air are easily worn and clogged. Long-term scouring by cotton fibers and dust can cause them to wear out or become clogged, requiring regular maintenance or replacement. Existing connection methods mostly use traditional flanges or threaded fastening, which is cumbersome to disassemble and assemble, requires special tools and takes a long time. This directly leads to production line downtime and reduces overall production efficiency. On the other hand, the weight, size and adhesion of gray cotton contained in different batches of raw cotton vary, and the intensity requirements of the rejection airflow also change accordingly. However, the jet nozzle diameter of existing rejection components is usually fixed and cannot be easily adjusted online, resulting in poor process adaptability of the device and difficulty in achieving the best rejection effect. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cotton inspection machine that facilitates automatic removal of gray cotton. It aims to improve the problems of complex and time-consuming replacement process of pneumatic removal components and inflexible adjustment of air jet intensity in existing cotton inspection machines that facilitate automatic removal of gray cotton. This utility model aims to provide a cotton inspection machine with an improved structure that can effectively solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cotton inspection machine for convenient automatic removal of gray cotton, comprising: an air pipe, a conveying pipe, a recovery pipe, an output pipe, a gray cotton storage container, a connecting pipe, a threaded pipe; as well as a quick-change mechanism and an adjustable diameter mechanism.

[0007] The quick-change mechanism is used to detachably connect the threaded tube to the connecting tube. A guide pin is fixed on the outer wall of the threaded tube. The quick-change mechanism includes a first fixed shaft rotatably connected to the connecting tube and a limiting plate fixed to the first fixed shaft. The limiting plate is used to selectively engage or release the guide pin. This structure enables the quick installation and disassembly of the threaded tube.

[0008] Furthermore, the adjustable nozzle mechanism is located at the end of the threaded tube away from the connecting tube. The adjustable nozzle mechanism includes a jet head threadedly connected to the threaded tube, multiple baffles, and a sliding rod. One end of the sliding rod is linked to the jet head, and the other end is connected to the baffle. By rotating the jet head, the rotational motion is converted into linear motion using the threaded joint, and the sliding rod drives the multiple baffles to slide relative to each other, thereby changing the size of the jet nozzle.

[0009] Preferably, the quick-change mechanism further includes a rotary handle for driving the first fixed shaft to rotate, a ratchet fixed to the rotary handle, and a limiting plate for engaging with the ratchet to lock the rotary handle.

[0010] Furthermore, the quick-change mechanism also includes a second fixed shaft and a spring. The limiting plate is fixedly connected to the second fixed shaft. One end of the spring abuts against the limiting plate and the other end abuts against the rotating handle, which is used to drive the limiting plate 107 to engage with the ratchet 105 to form a one-way locking structure to prevent the rotating handle from being accidentally loosened.

[0011] Preferably, the inner wall of the connecting pipe is provided with a groove that mates with the guide pin, which guides the guide pin when the threaded pipe is inserted, so as to ensure a smooth and accurate installation process.

[0012] Preferably, in order to achieve effective engagement of the guide pin, the outer periphery of the limiting disk is provided with a notch for engaging the guide pin. When the first fixed shaft rotates, the edge of the notch selectively abuts against or disengages from the guide pin, completing the locking or releasing action.

[0013] Preferably, the plurality of baffles are fitted around a central jet channel, and the relative sliding of the plurality of baffles is used to change the aperture of the central jet channel.

[0014] Preferably, in order to achieve stable sliding of the baffle, the adjustable diameter mechanism further includes a sliding block and a sliding groove fixed to the baffle, wherein the sliding block is slidably accommodated in the sliding groove.

[0015] Preferably, the jet head has a slot, and the sliding rod is slidably disposed in the slot to guide and limit the movement of the sliding rod, thereby ensuring the stability of the motion transmission.

[0016] This utility model has the following beneficial effects: In this invention, a quick-change mechanism is set up, which uses a rotating handle to drive the limiting plate and guide pin to achieve engagement and disengagement, and is supplemented by a ratchet and a limiting plate for reliable locking. This solves the problems of complex, time-consuming and labor-intensive replacement processes for components such as jet pipes in the prior art, which affect production efficiency. It achieves the effects of quick disassembly and assembly, convenient maintenance, and significantly reduced equipment downtime.

[0017] This invention, by setting an adjustable nozzle mechanism, uses a rotating jet head to drive a sliding rod and multiple baffles through threaded transmission, thereby achieving stepless adjustment of the jet nozzle diameter. This solves the problems of fixed jet intensity, inability to adapt to different types of cotton or impurity removal requirements, and easy waste of qualified cotton or incomplete removal in the prior art. It achieves the effect of accurately controlling the airflow intensity according to the actual working conditions, improving removal accuracy, and enhancing the applicability of the equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4 This utility model provides a cotton inspection machine that facilitates automatic removal of gray cotton. This cotton inspection machine aims to solve the technical problems of complex replacement process of pneumatic removal components and inflexible adjustment of air jet intensity in existing cotton inspection machines.

[0022] like Figure 1 and Figure 2 As shown, the cotton inspection machine for automatically removing ash cotton includes an air pipe 110 for supplying airflow, a conveying pipe 3 for conveying cotton, a recovery pipe 4, an output pipe 5, an ash cotton storage container 6 connected to the conveying pipe 3, a connecting pipe 101 fixedly connected to the air pipe 110, and a threaded pipe 205 detachably installed on the connecting pipe 101. To enable quick installation and removal of the threaded pipe 205 and convenient adjustment of the air jet diameter, the cotton inspection machine is further equipped with a quick-change mechanism 1 and an adjustable nozzle diameter mechanism 2. The quick-change mechanism 1 is located between the connecting pipe 101 and the threaded pipe 205 to enable quick connection and separation of the connecting pipe 101 and the threaded pipe 205. The adjustable diameter mechanism 2 is located at the end of the threaded pipe 205 away from the connecting pipe 101 to adjust the orifice size of the airflow ejected from the threaded pipe 205. During operation, the airflow enters the connecting pipe 101 through the air pipe 110, then flows through the threaded pipe 205, and is finally ejected from the air jet nozzle of the adjustable diameter mechanism 2 to blow away and remove the detected gray cotton.

[0023] Please refer to the following carefully. Figures 1 to 4The quick-change mechanism 1 includes a first fixed shaft 104, a limiting plate 103, a rotating handle 106, a ratchet 105, a limiting plate 107, a second fixed shaft 108, and a spring 109. A guide pin 102 is fixed on the outer wall of the threaded tube 205, and a groove is provided on the inner wall of the connecting tube 101 to mate with the guide pin 102, which is used to guide the guide pin 102 when the threaded tube 205 is inserted. The first fixed shaft 104 is rotatably connected to the connecting tube 101, the limiting plate 103 and the rotating handle 106 are both fixedly connected to the first fixed shaft 104, and the ratchet 105 is fixedly connected to the rotating handle 106. The outer periphery of the limiting plate 103 is provided with a notch for locking the guide pin 102. When the rotating handle 106 is rotated... When the handle 106 is turned, the first fixed shaft 104 drives the limiting plate 103 to rotate synchronously. The notch edge of the limiting plate 103 selectively abuts against or disengages from the guide pin 102, thereby achieving axial locking or release of the threaded tube 205. The second fixed shaft 108 is fixed to the outer wall of the connecting tube 101. The limiting plate 107 is fixedly connected to the second fixed shaft 108. One end of the spring 109 abuts against the limiting plate 107, and the other end abuts against the rotating handle 106. The elastic force of the spring 109 continuously drives the limiting plate 107 to mesh with the teeth of the ratchet 105, forming a one-way lock. This structure ensures the reliability of the connection and prevents the rotating handle 106 from accidentally loosening in a vibration environment.

[0024] In a preferred embodiment, to reliably lock the rotating handle 106, the quick-change mechanism 1 further includes a ratchet 105 fixedly connected to the rotating handle 106, and a limiting plate 107 for engaging with the ratchet 105. To achieve automatic reset of the limiting plate 107, the quick-change mechanism 1 is also provided with a second fixed shaft 108 and a spring 109. The limiting plate 107 is fixedly connected to the second fixed shaft 108, and one end of the spring 109 abuts against the limiting plate 107, and the other end abuts against the limiting plate 107. The elastic force of the spring 109 is used to drive the limiting plate 107 to engage with the ratchet 105.

[0025] As another preferred embodiment, in order to provide stable guidance when inserting the threaded tube 205, the inner wall of the connecting tube 101 is provided with a groove that cooperates with the guide pin 102; and, in order to achieve effective engagement of the guide pin 102, the outer periphery of the limiting disc 103 is provided with a notch for engaging the guide pin 102, and when the first fixed shaft 104 rotates, the edge of the notch selectively abuts against or disengages from the guide pin 102.

[0026] In another preferred embodiment, in order to achieve effective adjustment of the jet nozzle diameter, multiple baffles 202 are fitted around a central jet channel, and the relative sliding of the multiple baffles 202 is used to change the aperture of the central jet channel; in order to achieve stable sliding of the baffles 202, the adjustable nozzle diameter mechanism 2 also includes a sliding block 204 fixed to the baffle 202 and a groove 206 opened on the threaded tube 205, and the sliding block 204 is slidably accommodated in the groove 206.

[0027] In another preferred embodiment, in order to guide and limit the movement of the sliding rod 203, a slot 207 is provided on the jet head 201, and the sliding rod 203 is slidably disposed in the slot 207.

[0028] Working principle: When the testing machine is running, cotton is transported through the conveying pipe 3. When it passes the air jet, the airflow blows the cotton into the recovery pipe 4 along the air pipe 110, and then through the output pipe 5 to the cotton storage container 6. When performing air jet maintenance, the quick-change mechanism 1 is used. First, when installing the threaded pipe 205, the threaded pipe 205 is inserted into the connecting pipe 101. The guide pin 102 on the threaded pipe 205 will slide into the groove on the inner wall of the connecting pipe 101 and achieve positioning. At this time, the operator rotates the rotating handle 106. The rotating handle 106 drives the limiting plate 103 to rotate through the first fixed shaft 104 until the outer periphery of the limiting plate 103 has a notch for locking the guide pin 102, locking the guide pin 102. While rotating the rotating handle 106, the operator presses the limiting plate 103. The positioning plate 107 overcomes the elastic force of the spring 109, and the second fixed shaft 108 provides guide support to prevent the spring 109 from shifting when compressed. When the guide pin 102 is fully locked, the limiting plate 107 is released. Driven by the spring 109, the limiting plate 107 engages with the ratchet 105 fixed on the rotating handle 106, thereby forming a one-way lock on the rotating handle 106 to prevent the connection from coming loose during vibration. When it is necessary to disassemble and replace the threaded tube 205, simply press the limiting plate 107 to disengage it from the ratchet 105, and then rotate the rotating handle 106 in the opposite direction to release the guide pin 102 from the limiting plate 103, thereby quickly separating the threaded tube 205 from the connecting tube 101. The whole process does not require complicated tools and solves the problem of complicated replacement process of existing discarded parts. When adjusting the jet nozzle diameter, the operator rotates the jet head 201, which is located at the end of the threaded tube 205, through the adjustable nozzle diameter mechanism 2. Since the jet head 201 and the threaded tube 205 are connected by a thread, the rotational motion of the jet head 201 is converted into linear motion along the axis of the threaded tube 205. This linear motion is transmitted to multiple baffles 202 through the sliding rod 203, which is linked to the jet head 201. During the transmission process, the sliding rod 203 slides in the slot 207 of the threaded tube 205, and the sliding block 204, which is fixed on the baffle 202, slides in the groove 206. This drives the multiple baffles 202, which are arranged in close contact with each other around a central jet channel, to produce precise relative displacement, change the distance between the baffles 202, and finally realize the continuous adjustment of the diameter of the central jet channel. This solves the technical defect that the jet intensity of the existing rejection device cannot flexibly adapt to different working conditions.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
