Description

Technical Field

[0001] This utility model relates to the field of fixed cover plate needle cloth technology, and in particular to a fixed cover plate needle cloth with a hard microparticle composite coating. Background Technology

[0002] The carding cover is an important component in textile machinery, primarily used to fix and support the knitting needles and to comb the fibers. It typically consists of a needle plate and a carding cloth. The carding cloth is densely covered with numerous comb teeth or needle teeth, which comb the fibers, making them more fibrous. The carding cover protects the transmission system of the carding machine. It is usually made of metal, has a long, narrow shape, and has protrusions at the bottom that pass through openings in the transmission system and are secured there.

[0003] The existing method of connecting the cover strip to the frame using magnetic components carries the risk that the magnetic force may decrease or be lost after use, causing the soft cover strip to fall off the frame, damaging other parts of the carding machine or even rendering the entire machine unusable.

[0004] An existing patent (publication number: CN212451790U) discloses an elastic carding cloth for a quick-change carding strip, which includes a carding frame and a movable clamp fixed to one side of the carding frame; it also includes a carding strip, which includes a semi-enclosed structural member and an elastic carding cloth strip. The upper two ends of the semi-enclosed structural member have protruding parts, and the lower part has an opening. The carding strip, which is made by bonding steel sheets to the elastic carding cloth strip, has the serious consequence of detaching from the carding frame and damaging other parts of the carding machine, or even the entire carding machine.

[0005] To address the aforementioned issues, existing patents have proposed solutions that use adhesive bonding to connect the steel sheet to the cover strip made of elastic carding cloth strips. However, this method can lead to serious consequences, such as the cover strip detaching from the cover frame and damaging other parts of the carding machine or even the entire carding machine. Furthermore, when the carding cloth combs the fibers, the fibers adhere to the head of the carding cloth, which in turn affects the subsequent combing effect on the fibers. Summary of the Invention

[0006] The purpose of this utility model is to provide a fixed cover plate needle cloth with a hard microparticle composite coating. The fixed plate guides and limits the movable rod, thereby reducing the possibility of the movable rod deviating. The movable rod drives the connecting block to move, so that the scraper is driven to slide on the outer surface of the combing teeth, thereby pushing out the fibers adhering to the outer surface of the combing teeth, achieving a cleaning effect, and making it convenient to use, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fixed cover plate needle cloth with a hard microparticle composite coating, comprising a mounting shell, wherein a needle cloth body is horizontally placed inside the mounting shell, and a plurality of combing teeth are fixed at equal intervals on the upper surface of the needle cloth body, a cleaning mechanism for cleaning the combing teeth is provided on the upper surface of the mounting shell, and a pressing mechanism for pressing the needle cloth body is provided on the lower surface of the mounting shell.

[0008] The cleaning mechanism includes a scraper, which is placed on the upper surface of the mounting housing and slidably connected to the outer surface of the combing teeth. Both ends of the scraper are fixed with connecting blocks, and the lower surface of the connecting blocks is fixed with a movable rod. The outer surface of the movable rod is slidably connected with a fixing plate that is fixedly connected to the inner wall of the mounting housing.

[0009] Preferably, the lower end of the movable rod is fitted with a return spring that abuts against the fixed plate.

[0010] Preferably, the lower surface of the return spring is abutted against and connected to a movable rod that is fixedly connected to the fixed block, and the side wall of the fixed block is fixed with a pull rod that is slidably connected to the mounting shell.

[0011] Preferably, the outer surface of the comb teeth is coated with a wear-resistant coating, which is made of chromium or tungsten.

[0012] Preferably, the clamping mechanism includes a protective cover, which is disposed on the lower surface of the mounting shell, and an installation tube is fixed to the inner side of the protective cover.

[0013] Preferably, both ends of the protective cover are fixed with connecting strips that are plugged into the mounting shell.

[0014] Preferably, a piston is slidably connected inside the mounting tube, and a connector that is telescopically connected to the mounting tube is fixed on one side of the piston. Several ball bearings are installed on the upper surface of the connector.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the cleaning mechanism, the fixed plate guides and limits the movable rod, thereby reducing the possibility of the movable rod deviating. The movable rod drives the connecting block to move, causing the scraper to slide on the outer surface of the combing teeth, thereby pushing out the fibers adhering to the outer surface of the combing teeth, achieving the cleaning effect and making it convenient to use.

[0017] 2. The piston moves inside the mounting tube through the clamping mechanism, compressing the nitrogen stored inside the mounting tube and giving the mounting tube thrust. After the protective cover is fully assembled, the compressed nitrogen will push the connector to clamp the card cloth body, ensuring the stability of the combing teeth. Attached Figure Description

[0025] 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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A fixed cover plate needle cloth with a hard microparticle composite coating includes a mounting shell 1, a needle cloth body 2 is horizontally placed inside the mounting shell 1, a number of combing teeth 3 are fixed at equal intervals on the upper surface of the needle cloth body 2, a cleaning mechanism for cleaning the combing teeth 3 is provided on the upper surface of the mounting shell 1, and a pressing mechanism for pressing the needle cloth body 2 is provided on the lower surface of the mounting shell 1.

[0028] The cleaning mechanism includes a scraper 4, which is placed on the upper surface of the mounting shell 1 and slidably connected to the outer surface of the combing teeth 3. Both ends of the scraper 4 are fixed with connecting blocks 41. The lower surface of the connecting blocks 41 is fixed with a movable rod 43. The outer surface of the movable rod 43 is slidably connected with a fixing plate 42 that is fixedly connected to the inner wall of the mounting shell 1. The lower end of the movable rod 43 is fitted with a return spring 44 that abuts against the fixing plate 42. The lower surface of the return spring 44 abuts against the movable rod 43 that is fixedly connected to the fixing block 45. The side wall of the fixing block 45 is fixed with a pull rod 46 that is slidably connected to the mounting shell 1. The outer surface of the combing teeth 3 is coated with a wear-resistant coating 6, which is made of chromium or tungsten.

[0029] By adopting the above technical solution, before using the fixed cover plate needle cloth with hard microparticle composite coating, the mounting shell 1 is first assembled onto the equipment. During use, the combing teeth 3 on the needle cloth body 2 comb the fibers. The wear-resistant coating 6 coated on the outer surface of the combing teeth 3 first uses hard microparticles as the bottom layer, which can be diamond, and then coats chromium or tungsten to achieve the coating, which plays a leveling and strengthening function of filling pits and smoothing peaks, and improves the service life of the combing teeth 3. During combing, the limit adhering to the combing teeth 3 can be manually pulled by pulling the lever 46, which in turn drives the fixed block 45 to move, thereby pushing the return spring 44 to compress. At the same time, when the fixed block 45 moves, it drives the movable rod 43 to move vertically. The fixed plate 42 can guide and limit the movable rod 43, thereby reducing the possibility of the movable rod 43 deviating. At this time, the movable rod 43 drives the connecting block 41 to move, so that the scraper 4 is driven to slide on the outer surface of the combing teeth 3, thereby pushing out the fibers adhering to the outer surface of the combing teeth 3, achieving the cleaning effect and making it convenient to use.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the clamping mechanism includes a protective cover 5, which is placed on the lower surface of the mounting shell 1. An installation tube 52 is fixed inside the protective cover 5. Both ends of the protective cover 5 are fixed with connecting strips 51 that are inserted and connected to the mounting shell 1. A piston 53 is slidably connected inside the installation tube 52. A connecting piece 54 that is telescopically connected to the installation tube 52 is fixed on one side of the piston 53. Several balls 55 are installed on the upper surface of the connecting piece 54.

[0031] By adopting the above technical solution, when the combing teeth 3 need to be replaced, the protective cover 5 can be manually pushed. With the cooperation of the connecting strip 51, the protective cover 5 can be disassembled, and then the combing teeth 3 and the card cloth body 2 can be disassembled and replaced. After the replacement is completed, the protective cover 5 is assembled onto the mounting shell 1. Through the ball bearings 55 set on the connecting piece 54, the connecting piece 54 can slide on the card cloth body 2. When assembling the protective cover 5, it is necessary to press, so that the piston 53 moves in the mounting tube 52, compressing the nitrogen gas stored in the mounting tube 52, so that the mounting tube 52 has thrust. After the protective cover 5 is fully assembled, the compressed nitrogen gas will push the connecting piece 54 to press the card cloth body 2 tightly, ensuring the stability of the combing teeth 3.

[0032] Working principle: The wear-resistant coating 6 applied to the outer surface of the combing teeth 3 improves their service life. Manually pulling the lever 46 moves the fixing block 45, compressing the return spring 44. Simultaneously, the movement of the fixing block 45 causes the movable rod 43 to move vertically. This movable rod 43 then moves the connecting block 41, causing the scraper 4 to slide on the outer surface of the combing teeth 3, thus pushing out the fibers adhering to the outer surface. When the combing teeth 3 need to be replaced, the protective cover 5 can be manually pushed, with the cooperation of the connecting strip 51... The protective cover 5 can be disassembled, and the combing teeth 3 and the needle cloth body 2 can be disassembled and replaced. After replacement, the protective cover 5 is assembled onto the mounting shell 1. Through the ball bearings 55 provided on the connector 54, the connector 54 can slide on the needle cloth body 2. When assembling the protective cover 5, it is necessary to press, which causes the piston 53 to move in the mounting tube 52, compressing the nitrogen gas stored in the mounting tube 52, so that the mounting tube 52 has thrust. After the protective cover 5 is fully assembled, the compressed nitrogen gas will push the connector 54 to press the needle cloth body 2 tightly.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
