Description

Technical Field

[0001] This invention relates to the field of textile yarn processing technology, specifically to a textile yarn opening machine and opening method for preventing lint. Background Technology

[0002] In the textile production process, the opening of textile yarn is an extremely important initial step. Traditional textile yarn opening machines mainly use components such as the center roller and opening roller to open the material during operation. However, existing opening machines generally have a serious problem: during the discharge process, due to the lack of effective sealing measures, it is very easy to cause the phenomenon of lint to be generated.

[0003] Not only does the floating fluff cause serious pollution to the production workshop environment and affect the health of the workers in the workshop, causing respiratory diseases, but the fluff also flies around in the workshop and easily attaches to other parts of the equipment, increasing the difficulty of cleaning the equipment and even affecting the normal operation of the equipment, leading to frequent equipment failures, reducing production efficiency and increasing maintenance costs.

[0004] In addition, the lint may also mix into other textile materials being processed, negatively impacting product quality and leading to an increase in the defect rate. As people's requirements for production environment and product quality continue to improve, the shortcomings of existing textile yarn opening machines in preventing lint are becoming increasingly prominent, and there is an urgent need for a new type of opening machine that can effectively solve the problem of lint at the discharge. Summary of the Invention

[0005] The purpose of this invention is to provide a textile yarn opening machine and opening method that prevents lint from floating, so as to solve the problems mentioned in the background art, where the lack of effective sealing measures during the discharge of existing opening machines leads to serious lint floating, which in turn pollutes the workshop environment, endangers the health of workers, affects equipment operation, increases maintenance costs, and reduces product quality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a textile yarn opening machine for preventing lint, comprising a barrel body, a feed inlet fixedly provided at the upper end of the barrel body, a central motor fixedly installed on one side surface of the barrel body, one end of the output shaft of the central motor penetrating the inner surface of the barrel body, and a central roller fixedly connected to the end of the output shaft of the central motor located inside the barrel body, a rotating opening roller installed on the inner surface of the barrel body, arc-shaped toothed blocks provided on the outer surfaces of the central roller and the opening roller, and nail posts fixedly provided on the surface of the arc-shaped toothed blocks on the outer surfaces of the central roller and the opening roller, and a closed discharge mechanism provided on the surface of the barrel body. By closing the discharge of the opened material, the generation of lint during the discharge process is minimized.

[0007] A baffle block is fixedly installed on the inner surface of the barrel, and a clearance groove is opened on the side surface of the baffle block. One end of the shaft of the central roller passes through the outer surface of the barrel, and a central gear is fixedly connected to the end of the shaft of the central roller outside the barrel. A rotating transmission gear is installed on the outer surface of the barrel where the central gear is located. One end of the shaft of the loosening roller passes through the outer surface of the barrel, and a driven gear is fixedly connected to the end of the shaft of the loosening roller outside the barrel.

[0008] The closed discharge mechanism includes: a discharge cylinder, which is fixedly installed at both ends of the barrel body; a piston half-ring is fixedly installed on the inner surface of the discharge cylinder, and a piston column is installed inside the piston half-ring; a filter ejector is fixedly connected to the lower end of the piston column; a one-way pressure valve is fixedly installed on the outer surface of the upper end of the piston column; the upper end of the piston half-ring penetrates the outer surface of the discharge cylinder, and a solenoid valve is fixedly connected to the upper end of the piston half-ring; an air pump is fixedly installed on the outer surface of the upper end of the barrel body, and a connecting pipe is connected between the output end of the air pump and the solenoid valve; a connection port is opened on the outer surface of the discharge cylinder, and a baffle is fixedly installed on the inner surface of the discharge cylinder opposite to the connection port; a cloth bag is connected to one end of the connection port; an electric push rod is fixedly installed on the lower surface of the barrel body, and a temporary storage box is fixedly connected to one end of the electric push rod.

[0009] Preferably, the arc-shaped toothed blocks on the surface of the central roller and the arc-shaped toothed blocks on the surface of the opening roller are staggered, and the arc-shaped toothed blocks on the surface of the central roller are directly opposite the relief groove. Furthermore, the outer surface of the arc-shaped toothed blocks on the surface of the central roller is in contact with the inner surface of the relief groove. The transmission gear is meshed with the central gear and the driven gear, respectively.

[0010] By adopting the above technical solution, when the central motor drives the central roller to rotate, the opening roller can rotate synchronously through the transmission gear. The misalignment of the central roller and the opening roller teeth can fully tear and disperse the textile yarn material during rotation, thereby improving the opening effect. The cooperation between the central roller teeth and the relief groove can ensure that the material is stably opened in the barrel, preventing the material from falling downwards from the wrong direction to the bottom of the barrel during the opening process, thus ensuring the smooth progress of the opening work.

[0011] Preferably, the discharge cylinder has a C-shaped design with an opening at the lower end, and a partition plate is provided between the internal cavity of the discharge cylinder where the connection port is located and the internal cavity of the discharge cylinder where the upper end of the piston half ring is located.

[0012] Using the above technical solution, the C-shaped discharge cylinder facilitates the temporary storage box to receive materials from below, while the opening design also facilitates the entry and exit of materials. The partition plate can effectively prevent the gas from pushing the piston column at the upper end of the piston half-ring, thus avoiding unnecessary disturbance to the material on the connection port side. This ensures that the material can be stably discharged through the connection port during the closed discharge process, improving discharge efficiency and preventing the generation of lint.

[0013] Preferably, the piston half-ring and the piston rod are connected by sliding friction, the ejector filter frame is hollow, and a filter screen is provided on the inner surface of the ejector filter frame, and the outer surface of the ejector filter frame is in contact with the inner surface of the discharge cylinder.

[0014] Using the above technical solution, the piston half-ring and piston column are connected by sliding friction, which allows the gas provided by the air pump to smoothly push the piston column and push the filter frame to slide in the discharge cylinder. The outer side of the push filter frame is in contact with the inner side of the discharge cylinder, which can effectively prevent material from leaking from the side and ensure that the material is discharged smoothly through the connection port.

[0015] Preferably, one end of the one-way pressure valve penetrates the inner surface of the piston rod, and the piston rod, piston half-ring, and discharge cylinder are concentrically arranged, and the piston half-ring is hollow.

[0016] Using the above technical solution, the one-way pressure valve can ensure that the gas can only flow in one direction. When the filter frame is pushed out by the baffle, the pressure inside the piston column increases, the one-way pressure valve opens, and the gas is injected into one end of the discharge cylinder to clean up residual lint. The concentric arrangement of the piston column, piston half ring and discharge cylinder can ensure that the piston column is subjected to uniform force during sliding, and stably pushes the filter frame out, ensuring the smooth operation of closed discharge and lint cleaning.

[0017] Preferably, the temporary storage box has an arc-shaped design and is a hollow design with openings at both ends. Two temporary storage boxes are provided and are fixedly connected. The two temporary storage boxes are located at the lower ends of the barrel and the discharge cylinder, respectively. The temporary storage boxes and the discharge cylinder are concentrically arranged, and the two ends of the temporary storage boxes are respectively attached to the lower ends of the discharge cylinder.

[0018] Using the above technical solution, the arc-shaped temporary storage box is adapted to the shape of the barrel and the discharge cylinder, which facilitates the collection of materials falling from the barrel and reduces material accumulation and spillage. The two temporary storage boxes work alternately, one for receiving materials and the other for discharging materials in conjunction with the discharge cylinder, ensuring continuous material processing. The temporary storage box and the discharge cylinder are concentric and their ends fit together, which makes the material flow more smoothly during temporary storage and transfer, avoids material leakage, and further prevents the generation of lint.

[0019] Preferably, the two ends of the temporary storage box extend through the two end side surfaces of the barrel, and the temporary storage box and the barrel are designed concentrically, and the two end lower surfaces of the temporary storage box are respectively attached to the lower inner surface of the barrel.

[0020] The above technical solution is adopted, with the temporary storage box penetrating both ends of the barrel's side surface, facilitating the material to fall from the barrel into the temporary storage box. The concentric design with the barrel and the fit between the lower surfaces of both ends and the inner surface of the lower end of the barrel ensure that the temporary storage box is stable when receiving materials, preventing the materials from shifting or spilling during the transfer process. This ensures that the materials can enter the temporary storage box in an orderly manner, and together with the entire closed discharge system, effectively prevents the generation of floating lint.

[0021] A method for opening a textile yarn opening machine to prevent lint buildup includes the following steps:

[0022] S1. Material feeding: Pour the textile yarn material into the barrel through the feed port at the top of the barrel, so that the material enters the opening machine for processing;

[0023] S2, Opening and Loosening Start: Turn on the central motor. The output shaft of the central motor drives the central roller to rotate. When the central roller rotates, the central gear connected to one end outside the barrel rotates synchronously. The central gear drives the transmission gear meshing with it to rotate. The transmission gear drives the driven gear to rotate, thereby causing the opening roller equipped with the driven gear to start running.

[0024] S3. Material loosening: The arc-shaped toothed blocks and nails on the outer surfaces of the center roller and the loosening roller cooperate with each other. Due to the staggered arrangement of the toothed blocks, the nails tear and break up the material during rotation, changing the material from a compact state to a loose state, thus achieving initial loosening. At the same time, the arc-shaped toothed blocks on the surface of the center roller cooperate with the clearance grooves on the side surface of the baffle block to ensure stable loosening of the material in the barrel and prevent abnormal falling of the material during the loosening process.

[0025] S4. Discharge preparation: After the material is opened, it falls from one side of the barrel into the temporary storage box below. At this time, the electric push rod drives another temporary storage box that has received the material to move to the bottom of the discharge cylinder to prepare for the closed discharge.

[0026] S5. Closed Discharge: Start the air pump and control the gas flow direction through the solenoid valve. The gas enters the upper end of the piston half-ring in the discharge cylinder through the connecting pipe, pushing the piston column and the ejector filter frame connected to its lower end to slide downward in the discharge cylinder. Since the ejector filter frame is hollow and has a filter screen on the inside, the material in the temporary storage box and the discharge cylinder is pushed into the connected cloth bag through the connection port during the sliding process, completing the closed discharge and effectively preventing the flying of fluff.

[0027] S6. Residual Cleaning: When the filter rack moves to the point where it can no longer slide due to the baffle, the internal pressure of the piston increases, opening the one-way pressure valve and injecting gas into one end of the discharge cylinder. This gas cleans the residual lint inside the discharge cylinder and the temporary storage box, allowing the lint to be collected into the filter bag through the connection port, ensuring that the material is fully and completely collected and further reducing lint pollution.

[0028] Compared with the prior art, the beneficial effects of the present invention are: the anti-fluffing textile yarn opening machine:

[0029] 1. The dual discharge cylinder design allows the material to be collected in one discharge cylinder while the material inside the other discharge cylinder is pushed out through a closed system. Combined with the cloth bag design, this achieves closed collection of the material and effectively prevents the generation of lint.

[0030] 2. Furthermore, by controlling the air pump's outlet direction through a solenoid valve, the ejector filter frames on both sides can slide under the push of the gas, discharging the material through the connection port onto the connected cloth bag, thereby enabling the material to be automatically discharged.

[0031] 3. Furthermore, by pushing the filter frame into place and preventing it from sliding due to the baffle, the pressure inside the piston column increases, opening the one-way pressure valve and injecting gas into one end of the discharge cylinder. The injected gas cleans the residual lint inside the discharge cylinder and the temporary storage box, thereby ensuring that the material can be fully and completely collected.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1-10 The present invention provides a technical solution: a textile yarn opening machine for preventing lint from drifting. Example

[0045] This embodiment discloses: a barrel body 1, with a feed inlet 2 fixedly provided at the upper end of the barrel body 1, a central motor 3 fixedly installed on one side surface of the barrel body 1, one end of the output shaft of the central motor 3 penetrating through the inner surface of the barrel body 1, and a central roller 4 fixedly connected to the end of the output shaft of the central motor 3 located inside the barrel body 1, a rotating opening roller 10 installed on the inner surface of the barrel body 1, arc-shaped toothed blocks provided on the outer surfaces of the central roller 4 and the opening roller 10, and nail posts 11 fixedly provided on the surface of the arc-shaped toothed blocks on the outer surfaces of the central roller 4 and the opening roller 10;

[0046] The arc-shaped toothed blocks on the surface of the center roller 4 are offset from the arc-shaped toothed blocks on the surface of the opening roller 10, and the arc-shaped toothed blocks on the surface of the center roller 4 are directly opposite the relief groove 6. The outer surface of the arc-shaped toothed blocks on the surface of the center roller 4 is in contact with the inner surface of the relief groove 6. The transmission gear 8 is meshed with the center gear 7 and the driven gear 9 respectively.

[0047] Textile yarn material enters the barrel 1 through the feed inlet 2. At this time, the central motor 3 starts, and its output shaft drives the central roller 4 to rotate. One end of the central roller 4's shaft is connected to the central gear 7 outside the barrel 1. The central gear 7 meshes with the transmission gear 8, and the transmission gear 8 meshes with the driven gear 9. The driven gear 9 is mounted on the shaft of the opening roller 10. In this way, the power of the central motor 3 is transmitted to the opening roller 10, causing the opening roller 10 to start rotating. Both the outer surfaces of the central roller 4 and the opening roller 10 are equipped with belts... The arc-shaped teeth of the nail column 11 are staggered. During rotation, the center roller 4 and the opening roller 10 cooperate with each other. The nail column 11 tears and breaks up the textile yarn material entering the barrel 1, achieving initial opening and changing the material from a compact state to a loose state. The cooperation between the arc-shaped teeth on the surface of the center roller 4 and the relief groove 6 on the surface of the baffle block 5 ensures that the material is stably opened and loosened in the barrel 1, preventing the material from falling downwards from an incorrect direction to the bottom of the barrel 1 during the opening process. Example

[0048] This embodiment discloses, based on embodiment one, that: the surface of the barrel 1 is provided with a closed discharge mechanism, which minimizes the generation of lint during the discharge process by closing the material after it has been opened and discharging it.

[0049] A baffle block 5 is fixedly installed on the inner surface of the barrel 1, and a clearance groove 6 is opened on the side surface of the baffle block 5. One end of the shaft of the central roller 4 passes through the outer surface of the barrel 1, and a central gear 7 is fixedly connected to the end of the shaft of the central roller 4 located outside the barrel 1. A rotating transmission gear 8 is installed on the outer surface of the barrel 1 where the central gear 7 is located. One end of the shaft of the loosening roller 10 passes through the outer surface of the barrel 1, and a driven gear 9 is fixedly connected to the end of the shaft of the loosening roller 10 located outside the barrel 1.

[0050] The closed discharge mechanism includes: a discharge cylinder 12, which is fixedly disposed at both ends of the barrel body 1. A piston semi-ring 13 is fixedly disposed on the inner surface of the discharge cylinder 12, and a piston rod 14 is installed inside the piston semi-ring 13. A filter ejector 15 is fixedly connected to the lower end of the piston rod 14. A one-way pressure valve 16 is fixedly disposed on the outer surface of the upper end of the piston rod 14. The upper end of the piston semi-ring 13 penetrates the outer surface of the discharge cylinder 12, and the upper end of the piston semi-ring 13 is fixedly connected to... A solenoid valve 17 is connected to the upper outer surface of the barrel 1, an air pump 18 is fixedly installed, and the output end of the air pump 18 is connected to the solenoid valve 17 via a connecting pipe 19. A connection port 20 is opened on the outer surface of the discharge cylinder 12, and a baffle 21 is fixedly installed on the inner surface of the discharge cylinder 12 opposite to the connection port 20. A cloth bag is connected to one end of the connection port 20. An electric push rod 22 is fixedly installed on the lower surface of the barrel 1, and a temporary storage box 23 is fixedly connected to one end of the electric push rod 22.

[0051] The discharge cylinder 12 has a C-shaped design with an opening at the lower end. A partition plate is provided between the internal cavity of the discharge cylinder 12 where the connection port 20 is located and the internal cavity of the discharge cylinder 12 where the upper end of the piston half ring 13 is located.

[0052] The piston half ring 13 and the piston rod 14 are connected by sliding friction. The ejector filter frame 15 is hollow and a filter screen is provided on the inner surface of the ejector filter frame 15. The outer surface of the ejector filter frame 15 is in contact with the inner surface of the discharge cylinder 12.

[0053] One end of the one-way pressure valve 16 penetrates the inner surface of the piston rod 14, and the piston rod 14, piston half ring 13 and discharge cylinder 12 are concentrically arranged, and the piston half ring 13 is hollow.

[0054] The temporary storage box 23 has an arc-shaped design and is hollow with openings at both ends. There are two temporary storage boxes 23, which are fixedly connected. The two temporary storage boxes 23 are located at the lower ends of the barrel 1 and the discharge cylinder 12, respectively. The temporary storage box 23 and the discharge cylinder 12 are concentrically arranged, and the two ends of the temporary storage box 23 are respectively attached to the lower ends of the discharge cylinder 12.

[0055] The two ends of the temporary storage box 23 penetrate the two side surfaces of the barrel 1 respectively, and the temporary storage box 23 and the barrel 1 are concentrically designed. The two lower surfaces of the temporary storage box 23 are respectively attached to the lower inner surface of the barrel 1.

[0056] After being opened, the material falls from one side of the barrel 1 into the interior of the temporary storage box 23. After receiving the opened material, the other temporary storage box 23 is driven by the electric push rod 22 to the bottom of the discharge cylinder 12 to prepare for the closed discharge operation.

[0057] When the material is discharged in a closed manner, the air pump 18 is started and the gas flow direction is controlled by the solenoid valve 17. The gas enters the upper end of the piston half ring 13 inside the discharge cylinder 12 where the temporary storage box 23 is located through the connecting pipe 19, pushing the piston column 14 and the push-out filter frame 15 connected to it to slide downward in the discharge cylinder 12. Since the push-out filter frame 15 is hollow and has a filter screen on the inside, during the sliding process, the material in the temporary storage box 23 and the discharge cylinder 12 is pushed into the connected cloth bag through the connection port 20, realizing closed discharge and effectively preventing the fluff from flying into the outside environment.

[0058] When the filter ejector 15 moves into position and is stopped by the baffle 21, preventing it from sliding further, the internal pressure of the piston column 14 increases, opening the one-way pressure valve 16 and injecting gas into one end of the discharge cylinder 12. This gas cleans the residual lint inside the discharge cylinder 12 and the temporary storage box 23, allowing the lint to be collected into the filter bag through the connection port 20, ensuring that the material is fully and completely collected and further reducing lint pollution.

[0059] During the discharge process, the temporary storage box 23 can temporarily store the material falling from the barrel 1, ensuring that the material can be collected in an orderly manner for subsequent processing. At the same time, it can also prevent the material from falling during the discharge process. Together with the entire closed discharge system, it can effectively prevent the generation of floating lint.

[0060] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are merely specific embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the protection scope of the present invention.

S4. Discharge preparation: After the material is opened, it falls from one side of the barrel (1) into the temporary storage box (23) below. At this time, the electric push rod (22) drives another temporary storage box (23) that has received the material to move to the bottom of the discharge cylinder (12) to prepare for the closed discharge. S5. Closed discharge: Start the air pump (18) and control the gas flow direction through the solenoid valve (17). The gas enters the upper end of the piston half ring (13) in the discharge cylinder (12) through the connecting pipe (19), pushing the piston column (14) and the push-out filter frame (15) connected to its lower end to slide downward in the discharge cylinder (12). Since the push-out filter frame (15) is hollow and has a filter screen on the inside, during the sliding process, the material in the temporary storage box (23) and the discharge cylinder (12) is pushed into the connected cloth bag through the connection port (20) to complete the closed discharge and effectively prevent the fluff from flying. S6. Residual cleaning: When the filter rack (15) moves to the point where it is limited by the baffle (21) and can no longer slide, the internal pressure of the piston column (14) increases, opening the one-way pressure valve (16), and gas is injected into one end of the discharge cylinder (12). This gas cleans the residual fluff inside the discharge cylinder (12) and the temporary storage box (23), so that the fluff is collected into the cloth bag through the connection port (20), ensuring that the material is fully and completely collected, and further reducing fluff pollution.
