Description

Technical Field

[0001] This application relates to the field of cotton opener technology, and in particular to an iron removal device for a cotton opener. Background Technology

[0002] A cotton opener is mainly used for the preliminary processing of cotton in cotton bales. Through mechanical tearing and beating, it loosens the compressed cotton, making the cotton clumps smaller and looser, removing some impurities, and creating a more loose and uniform cotton structure, providing a suitable raw material base for subsequent carding and other processes. The raw cotton entering the opener may contain impurities such as broken iron pieces, iron wire, and iron filings. These impurities should be removed promptly, otherwise they may damage internal machine parts or cause a fire.

[0003] In related technologies, traditional cotton opener iron removal devices are often only equipped with simple magnetic suction components, which have limited iron removal effect. During the process of conveying raw cotton into the cotton opener, iron metal impurities cannot be completely and fully removed from the raw cotton. Some iron metal impurities in the raw cotton will not be completely removed, and some iron metal impurities will still enter the cotton opener, damaging the internal parts of the machine.

[0004] Therefore, we propose an iron removal device for cotton openers to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide an iron removal device for a cotton opener, which has the effect of improving the comprehensiveness and thoroughness of iron removal from raw cotton.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a cotton opener iron removal device, comprising a cotton opener body, two support plates fixedly mounted on the cotton opener body, and a vibrating feeding mechanism and a magnetic iron removal mechanism disposed between the two support plates. A feed inlet is provided on the right side of the cotton opener body, with the feed inlet symmetrically distributed on the front and rear sides of the two support plates. Multiple conveying rollers, evenly spaced, are rotatably mounted between the two support plates, and the same conveyor belt is wound around the multiple conveying rollers. A motor is fixedly mounted on the front support plate of the two support plates, and the output shaft end of the motor is fixedly connected to the front end of the rightmost conveying roller. The fixed connection and vibrating feeding mechanism includes a stepped feeding plate, four sets of elastic support components and a drive component. The stepped feeding plate is located between two support plates and below the left side of the conveyor belt. The left end of the stepped feeding plate passes through the feed inlet. The four sets of elastic support components are all set below the stepped feeding plate and are symmetrically distributed in pairs. The four sets of elastic support components are used to support the stepped feeding plate. The drive component is used to control the vibration of the stepped feeding plate. The magnetic attraction iron removal mechanism includes a crossbeam plate and an electromagnet. The crossbeam plate is fixedly installed between two support plates and above the conveyor belt. The electromagnet is fixedly installed at the bottom of the crossbeam plate.

[0007] By adopting the above technical solution, the conveyor belt is used to horizontally and linearly transport raw cotton, so that the raw cotton on the conveyor belt can continuously fall onto the stepped feeding plate. The stepped feeding plate is supported by four sets of elastic support components, which can generate vibration under the action of the drive component. When the raw cotton falls onto the stepped feeding plate, its vibration can make the raw cotton pass through the feed port and enter the cotton opener body evenly and efficiently. By using the magnetic force generated by the electromagnet when it is energized, the raw cotton passing on the conveyor belt can be initially removed from the iron.

[0008] A further configuration of this application is as follows: the elastic support assembly includes a fixed plate, a sliding rod, and a spring. The fixed plate is fixedly installed on one side wall of the support plate and located below the stepped feeding plate. The sliding rod slides through the fixed plate, and the top end of the sliding rod is fixedly connected to the bottom of the stepped feeding plate. The spring is sleeved on the sliding rod, and the bottom end of the spring is fixedly connected to the top of the fixed plate, while the top end of the spring is fixedly connected to the bottom of the stepped feeding plate.

[0009] By adopting the above technical solution, the stepped feeding plate can be supported by the synergistic action of the fixed plate, sliding rod and spring.

[0010] A further provision of this application is that a limit stop is fixedly installed at the bottom end of the slide rod.

[0011] By adopting the above technical solution, the upward movement of the slide bar can be limited, preventing the slide bar from detaching from the fixed plate and also preventing the stepped feeding plate from colliding with the conveyor belt.

[0012] A further configuration of this application is as follows: the drive assembly includes a drive shaft, a cam, a main pulley, a secondary pulley, and a belt. The drive shaft is rotatably mounted between two support plates and located below the stepped feed plate. The cam is fixedly mounted on the drive shaft and contacts the bottom of the stepped feed plate. The main pulley is fixedly mounted on the front end of the leftmost conveying roller, and the secondary pulley is fixedly mounted on the front end of the drive shaft. The belt is wound around the main pulley and the secondary pulley.

[0013] By adopting the above technical solution, the transmission action of the main pulley, the auxiliary pulley and the belt can make the conveying roller and the drive shaft rotate simultaneously. The drive shaft rotates the cam, and since the cam is in contact with the bottom of the stepped feeding plate, the rotation of the cam will continuously push up and release the stepped feeding plate, causing it to vibrate up and down with the help of the spring.

[0014] A further provision of this application is that the diameter of the main pulley is larger than the diameter of the auxiliary pulley.

[0015] By adopting the above technical solution, an acceleration effect can be achieved, making the speed of the drive shaft higher than that of the conveyor roller, thereby ensuring that the cam can lift the stepped feed plate at a higher frequency and enhance the vibration effect.

[0016] A further feature of this application is that the number of cams is set to multiple, and the multiple cams are distributed at equal intervals.

[0017] By adopting the above technical solution, it is possible to ensure that all parts of the stepped feeding plate are subjected to uniform force and vibration, thereby enhancing the stability of the stepped feeding plate vibration.

[0018] A further provision of this application is that the magnetic iron removal mechanism further includes multiple crossbeam plates and multiple electromagnets. The multiple crossbeam plates are all fixedly installed between two support plates and are evenly arranged. The multiple crossbeam plates are all located above the stepped feeding plate and are inclined. The multiple electromagnets are respectively fixedly installed at the bottom of the corresponding crossbeam plates.

[0019] By adopting the above technical solution and utilizing multiple inclined electromagnets, the iron removal effect can be further improved. By feeding the raw cotton under the vibration of the stepped feeding plate, the iron metal impurities can be removed from the raw cotton more quickly. This ensures that all parts of the raw cotton are fully subjected to the magnetic force of the electromagnets, improving the comprehensiveness and thoroughness of iron removal. It effectively prevents iron impurities from entering the main body of the cotton opener and causing damage to subsequent processing, thus ensuring the quality of cotton opening.

[0020] A further feature of this application is that the stepped feeding plate is inclined, and the front and rear side walls of the stepped feeding plate slide in contact with the side walls of the two support plates that are close to each other.

[0021] By adopting the above technical solution, the stepped feeding plate is set at an angle, which can ensure the smooth and efficient entry of raw cotton into the main body of the cotton opener. The front and rear side walls of the stepped feeding plate are designed to slide in contact with the side walls of the two support plates that are close to each other, which can make the stepped feeding plate move smoothly and reduce the friction during movement.

[0022] A further provision of this application is that a sealing mechanism is provided on the right side of the main body of the cotton opener. The sealing mechanism includes a mounting base, an electric telescopic rod, and a baffle. The mounting base is fixedly installed on the outer right side wall of the main body of the cotton opener and located above the feed inlet. The electric telescopic rod is fixedly installed on the mounting base. The baffle is fixedly installed on the output shaft end of the electric telescopic rod. The bottom of the baffle is located between two support plates. The front and rear side walls of the baffle are in sliding contact with the side walls of the two support plates that are close to each other.

[0023] By adopting the above technical solution, the baffle can be raised and lowered using an electric telescopic rod. When it is necessary to remove ferrous metal impurities from electromagnets one and two, ferrous metal impurities can be prevented from entering the main body of the cotton opener through the feed inlet.

[0024] A further feature of this application is that a supporting upright plate is fixedly installed at the bottom of both support plates.

[0025] By adopting the above technical solutions, the support plate can be reinforced and its stability improved.

[0026] This application includes at least one of the following beneficial technical effects:

[0027] 1. This application utilizes a conveyor belt for horizontal linear conveying of raw cotton, and in conjunction with an electromagnet that generates magnetic force when energized, it can adsorb iron metal impurities in the raw cotton, thereby achieving initial iron removal.

[0028] 2. This application utilizes a vibrating feeding mechanism, in conjunction with multiple inclined electromagnets, to achieve secondary iron removal. When the raw cotton is fed under the vibration of the stepped feeding plate, it can accelerate the removal of ferrous metal impurities from the raw cotton, thereby ensuring that all parts of the raw cotton are fully subjected to the magnetic force of the electromagnets, improving the comprehensiveness and thoroughness of iron removal from the raw cotton.

[0029] 3. This application utilizes a blocking mechanism to prevent ferrous metal impurities from entering the main body of the cotton opener through the feed inlet when it is necessary to remove ferrous metal impurities from electromagnets one and two. Attached Figure Description

[0037] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0038] See Figures 1-6 This application provides a cotton opener iron removal device, including a cotton opener body 1, two support plates 2 fixedly mounted on the cotton opener body 1, and a vibrating feeding mechanism and a magnetic iron removal mechanism disposed between the two support plates 2. The cotton opener body 1 has a feed inlet on the right side, and the two support plates 2 are symmetrically distributed on the front and rear sides of the feed inlet. Support plates are fixedly mounted on the bottom of the two support plates 2. Multiple conveying rollers 3 are rotatably mounted between the two support plates 2 and are distributed at equal intervals. The same conveyor belt 4 is wound around the multiple conveying rollers 3. The conveyor belt 4 is used for horizontal linear conveying of raw cotton. A motor 5 is fixedly mounted on the support plate 2 located on the front side of the two support plates 2. The output shaft end of the motor 5 is fixedly connected to the front end of the rightmost conveying roller 3.

[0039] In this embodiment, the vibrating feeding mechanism includes a stepped feeding plate 6, four sets of elastic support components, and a driving component. The stepped feeding plate 6 is located between two support plates 2 and below the left side of the conveyor belt 4. The stepped feeding plate 6 is inclined. The front and rear side walls of the stepped feeding plate 6 are in sliding contact with the side walls of the two support plates 2 that are close to each other. The left end of the stepped feeding plate 6 passes through the feed inlet. The four sets of elastic support components are all arranged below the stepped feeding plate 6 and are symmetrically distributed in pairs. The four sets of elastic support components are used to support the stepped feeding plate 6. The driving component is used to control the vibration of the stepped feeding plate 6.

[0040] In this embodiment, the elastic support assembly includes a fixed plate 7, a slide rod 8, and a spring 9. The fixed plate 7 is fixedly installed on one side wall of the support plate 2 and located below the stepped feeding plate 6. The slide rod 8 slides through the fixed plate 7, and the top end of the slide rod 8 is fixedly connected to the bottom of the stepped feeding plate 6. The spring 9 is sleeved on the slide rod 8, and the bottom end of the spring 9 is fixedly connected to the top of the fixed plate 7. The top end of the spring 9 is fixedly connected to the bottom of the stepped feeding plate 6. A limit stop 10 is fixedly installed at the bottom end of the slide rod 8. The drive assembly includes a drive shaft 11, a cam 12, a main pulley 13, a secondary pulley 14, and a belt 15. The drive shaft 11 is rotatably installed between the two support plates 2 and located below the stepped feeding plate 6. Wheel 12 is fixedly mounted on drive shaft 11. Cam 12 contacts the bottom of stepped feed plate 6. Main pulley 13 is fixedly mounted on the front end of leftmost conveyor roller 3. Auxiliary pulley 14 is fixedly mounted on the front end of drive shaft 11. Belt 15 is wound around main pulley 13 and auxiliary pulley 14. Four sets of elastic support components can stably support stepped feed plate 6. Under the action of drive components, stepped feed plate 6 can vibrate. When raw cotton falls on stepped feed plate 6, its vibration can make the raw cotton pass through the feed inlet into cotton opener body 1 evenly and efficiently. When the raw cotton vibrates with stepped feed plate 6, the iron metal impurities mixed in it are more easily separated from the raw cotton.

[0041] In this embodiment, the diameter of the main pulley 13 is larger than that of the auxiliary pulley 14. This design can achieve a speed-increasing effect, so that the rotational speed of the drive shaft 11 is higher than that of the conveying roller 3, thereby ensuring that the cam 12 can lift the stepped feed plate 6 at a higher frequency and enhance the vibration effect.

[0042] In this embodiment, the number of cams 12 is set to multiple, and the multiple cams 12 are distributed at equal intervals. This design can ensure that each part of the stepped feed plate 6 is subjected to uniform force and vibration, and enhance the vibration stability of the stepped feed plate 6.

[0043] In this embodiment, the magnetic attraction iron removal mechanism includes a crossbeam plate 16 and an electromagnet 17. The crossbeam plate 16 is fixedly installed between two support plates 2 and located above the conveyor belt 4. The electromagnet 17 is fixedly installed at the bottom of the crossbeam plate 16. The magnetic force generated by energizing the electromagnet 17 can perform preliminary iron removal on the raw cotton passing through the conveyor belt 4. The magnetic attraction iron removal mechanism also includes multiple crossbeam plates 18 and multiple electromagnets 19. The multiple crossbeam plates 18 are all fixedly installed between two support plates 2 and are evenly arranged. All are located above the stepped feeding plate 6 and are set at an angle. Multiple electromagnets 2 19 are fixedly installed at the bottom of the corresponding crossbeam plate 2 18. By using multiple inclined electromagnets 2 19 to feed the raw cotton in the vibrating state of the stepped feeding plate 6, it can be ensured that all parts of the raw cotton can be fully subjected to the magnetic force of the electromagnets 2 19, which can further improve the iron removal effect, improve the comprehensiveness and thoroughness of iron removal, and thus effectively prevent iron impurities from entering the cotton opener body 1 and causing damage to subsequent processing, thus ensuring the quality of cotton opening.

[0044] In this embodiment, a sealing mechanism 20 is provided on the right side of the cotton opener body 1. The sealing mechanism includes a mounting base 201, an electric telescopic rod 202, and a baffle 203. The mounting base 201 is fixedly installed on the outer right side wall of the cotton opener body 1 and located above the feed inlet. The electric telescopic rod 202 is fixedly installed on the mounting base 201. The baffle 203 is fixedly installed on the output shaft end of the electric telescopic rod 202. The bottom of the baffle 203 is located between the two support plates 2. The front and rear side walls of the baffle 203 are in sliding contact with the side walls of the two support plates 2 that are close to each other. The electric telescopic rod 202 can be used to control the raising and lowering of the baffle 203. When it is necessary to remove ferrous metal impurities from electromagnet 17 and electromagnet 29, it can prevent ferrous metal impurities from entering the cotton opener body 1 through the feed inlet.

[0045] In this embodiment, it should be noted that the motor 5, electromagnet 17, electromagnet 29 and electric telescopic rod 202 can all be purchased on the market, and their wiring connection and control methods are mature technologies in this field and have been fully disclosed, so they will not be described in detail here.

[0046] With the above structure, when the iron removal device for the cotton opener provided in this application is in use, the motor 5 is started and the output shaft of the motor 5 drives the rightmost conveyor roller 3 to rotate. Since multiple conveyor rollers 3 are connected by the conveyor belt 4, the other conveyor rollers 3 also rotate synchronously, realizing the cyclic operation of the conveyor belt 4. When the leftmost conveyor roller 3 rotates, the main pulley 13 fixed on it rotates synchronously. The main pulley 13 drives the auxiliary pulley 14 to rotate through the belt 15, thereby causing the drive shaft 11 to rotate. Since the diameter of the main pulley 13 is larger than that of the auxiliary pulley 14, the drive shaft 11 achieves accelerated rotation. Multiple cams 12 fixed on the drive shaft 11 rotate synchronously with the drive shaft 11. During the rotation, the profile of the cam 12 continuously pushes up the bottom of the stepped feeding plate 6. When the protruding part of the cam 12 leaves the stepped feeding plate 6, under the elastic force of the spring 9 in the elastic support component, the stepped feeding plate 6 falls back down. This cycle continues, and the stepped feeding plate 6 vibrates up and down under the continuous rotation of the cam 12.

[0047] By spreading the raw cotton on the conveyor belt 4, the raw cotton can be conveyed horizontally in a straight line, so that the raw cotton continuously falls on the stepped feeding plate 6. When the raw cotton continuously passes under the electromagnet 17, the electromagnet 17 is energized to generate magnetic force, which can adsorb the iron metal impurities in the raw cotton, thus achieving the initial iron removal.

[0048] As the raw cotton continuously falls onto the inclined stepped feeding plate 6, under the vibration generated by the stepped feeding plate 6, the raw cotton will gradually move towards the feed port on the main body 1 of the cotton opener along the inclined direction of the stepped feeding plate 6. When the raw cotton continuously passes under multiple inclined electromagnets 19, the electromagnets 19 generate magnetic force when energized, which can adsorb the remaining iron metal impurities in the raw cotton again, realizing secondary iron removal. Furthermore, by feeding the raw cotton under the vibration of the stepped feeding plate 6, the iron metal impurities can be removed from the raw cotton more quickly, thereby ensuring that all parts of the raw cotton are fully subjected to the magnetic force of the electromagnets 19, improving the comprehensiveness and thoroughness of iron removal.

[0049] After complete iron removal, the raw cotton continuously and smoothly enters the cotton opener body 1 along the inclined direction of the stepped feeding plate 6. By controlling the operation of the cotton opener body 1, the raw cotton can be opened.

[0050] After the work is completed, stop the motor 5. By controlling the extension rod 202 to extend, the baffle 203 can be pushed down until it contacts the stepped feeding plate 6. Then, the power supply of electromagnet 17 and multiple electromagnets 29 is disconnected in sequence. The magnetic force of electromagnet 17 and multiple electromagnets 29 disappears. Then, collection tools such as collection boxes and collection bags can be used to collect the iron metal impurities on electromagnet 17 and multiple electromagnets 29 in sequence. During this process, the baffle 203 can be used to block the iron metal impurities and prevent the scattered iron metal impurities from entering the cotton opener body 1 through the feed port.
