Description

Technical Field

[0001] This utility model relates to the field of anti-blocking and anti-entanglement technology, specifically to an anti-blocking and anti-entanglement feeding mechanism for a short fiber pretreatment device. Background Technology

[0002] In the fields of textiles, papermaking, biomass energy, and agricultural waste treatment, short-fiber raw materials (such as cotton linters, hemp fiber scraps, wood pulp short fibers, and straw fragments) are often used as primary raw materials in pretreatment processes, such as the feeding stage before washing, opening, cutting, cooking, or pulping. Due to the physical characteristics of short fibers, such as short length (usually 5–30 mm), high bulkiness, high surface friction coefficient, and easy moisture absorption and clumping, they are prone to blockage, bridging, entanglement, or accumulation in key parts such as conveying channels, feed rollers, pressure rollers, or guide plates during continuous feeding. This seriously affects the continuous operating efficiency of the equipment, and may even lead to the shutdown of the entire machine, increasing the frequency of manual cleaning and safety risks.

[0003] In existing devices, short fibers form "arched bridges" in the hopper or feed inlet due to their own weight compression and the cohesive force between fibers, resulting in poor material discharge and blockage inside. Furthermore, it is difficult to separate the tangled short fibers during use, causing inconvenience in subsequent operations. Based on this, this utility model designs an anti-blocking and anti-tangling feeding mechanism for short fiber pretreatment devices to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging and anti-winding feeding mechanism for a short fiber pretreatment device, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A short fiber pretreatment device includes an anti-clogging and anti-entanglement feeding mechanism, comprising a processor, an anti-clogging mechanism, and an anti-entanglement mechanism. The anti-clogging mechanism includes a servo motor, which is externally mounted on the processor. A rotating rod is mounted on the output shaft end of the servo motor. A fixing ring is fixedly mounted on the outside of the rotating rod. Several cutting blades are symmetrically mounted on the outside of the fixing ring. Several strip rods are symmetrically mounted on the outside of the fixing ring. Several loosening needles are mounted on the outside of each strip rod. During rotation, the strip rods, in cooperation with the loosening needles, cut the "arched bridges" formed by the short fibers, preventing the short fibers from clogging inside the processor.

[0006] The anti-tangling mechanism includes a hanging motor, which is fixedly installed at the bottom of the processor. The output shaft of the hanging motor passes through the processor and into its interior, with a rotating plate installed at the end. Several anti-tangling plates are symmetrically installed on the top of the rotating plate. The centrifugal force generated by the hanging motor and rotating plate during rotation separates the short fibers on the outside of the rotating plate, preventing them from tangling together.

[0007] Preferably, a fixed bearing is installed on the side of the processor away from the servo motor, the free end of the rotating rod is connected to the fixed bearing, and a protective sleeve is fitted over the rotating rod, with the free end of the protective sleeve connected to the processor. The protective sleeve protects the fixed bearing, preventing short fibers from entering the interior of the fixed bearing and causing the rotating rod to malfunction.

[0008] Preferably, a first rotating anti-bridging knife set is installed on the side of the rotating rod closest to the servo motor, and a second rotating anti-bridging knife set is installed on the side of the rotating rod closest to the protective sleeve. The combined use of the first and second rotating anti-bridging knife sets can prevent entanglement or accumulation between short fibers.

[0009] Preferably, the processor has symmetrically installed support rods inside, with a strip-shaped guide plate installed at the top of the support rods and an arc-shaped guide plate installed at the bottom of the strip-shaped guide plate to cooperate with the rotating plate. A connecting cloth is installed between the top of the strip-shaped guide plate and the inside of the processor. The short fibers processed by the anti-blocking mechanism are conveyed through the combined use of the strip-shaped guide plate and the arc-shaped guide plate.

[0010] Preferably, the processor has an external discharge port and an internal feed port on its top. Short fibers are added to the processor through the feed port and discharged from the processor through the discharge port.

[0011] Preferably, a vibrator is mounted externally on the processor, with the output shaft of the vibrator penetrating the processor and extending into its interior, and a vibrating plate mounted at the end. The vibrator and vibrating plate work together to vibrate and lower short fibers entering the processor.

[0012] Preferably, a first flexible cloth is installed on the top of the vibrating plate, and a second flexible cloth is installed on the bottom of the vibrating plate. The free ends of both the first and second flexible cloths are connected to the interior of the processor. The combined use of the first and second flexible cloths prevents short fibers from entering the angle between the vibrating plate and the vibrator, thus avoiding a reduction in the vibration force of the vibrating plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model can separate the "arched bridge" formed by short fibers during movement through an anti-blocking mechanism. The anti-blocking mechanism includes a cutting blade, a strip rod, and a loosening needle. In daily use, the servo motor is started, and the servo motor drives the fixed ring to rotate. During the rotation of the fixed ring, the cutting blade cuts the internal short fibers. During the rotation of the fixed ring, the strip rod rotates. During the rotation of the strip rod, it works in conjunction with the loosening needle to cut the "arched bridge" formed by the short fibers, thus preventing the short fibers from forming a blockage inside the processor. 2. This utility model can separate short fibers through an anti-tangling mechanism. The anti-tangling mechanism includes a hanging motor, a rotating plate, and an anti-tangling plate. When the device is used to pre-process the short fibers, the short fibers fall onto the rotating plate through the strip guide plate. The hanging motor is started, and the hanging motor drives the rotating plate to rotate. The rotating plate generates centrifugal force during rotation, which separates the short fibers on the outside of the rotating plate, preventing the short fibers from connecting together and causing tangling.

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 This utility model provides a technical solution: A short fiber pretreatment device includes an anti-clogging and anti-entanglement feeding mechanism, comprising a processor 1, an anti-clogging mechanism, and an anti-entanglement mechanism. The anti-clogging mechanism includes a servo motor 21. The servo motor 21 is externally mounted on the processor 1. A rotating rod 22 is mounted on the output shaft end of the servo motor 21. A fixing ring 31 is fixedly mounted on the outside of the rotating rod 22. Several cutting blades 32 are symmetrically mounted on the outside of the fixing ring 31. Several strip rods 33 are symmetrically mounted on the outside of the fixing ring 31. Several loosening needles 34 are mounted on the outside of each strip rod 33. During rotation, the strip rods 33, in cooperation with the loosening needles 34, cut the "arched bridges" formed by the short fibers, thus preventing the short fibers from clogging inside the processor 1.

[0019] The anti-tangling mechanism includes a hanging motor 51, which is fixedly mounted on the bottom of the processor 1. The output shaft of the hanging motor 51 passes through the processor 1 and extends into its interior, with a rotating plate 52 mounted at the end. Several anti-tangling plates 53 are symmetrically mounted on the top of the rotating plate 52. Centrifugal force is generated during the rotation of the hanging motor 51 and the rotating plate 52, which separates the short fibers on the outside of the rotating plate 52, preventing them from tangling together. A fixed bearing 25 is installed on the side of the processor 1 away from the servo motor 21. The free end of the rotating rod 22 is connected to the fixed bearing 25, which fixes the rotating rod 22. A protective sleeve 26 is fitted over the rotating rod 22, and the free end of the protective sleeve 26 is connected to the processor 1. The protective sleeve 26 protects the fixed bearing 25, preventing short fibers from entering the interior of the fixed bearing 25 and causing the rotating rod 22 to malfunction. A first rotating anti-bridging knife assembly 23 is installed on the side of the rotating rod 22 closest to the servo motor 21, and a second rotating anti-bridging knife assembly 24 is installed on the side of the rotating rod 22 closest to the protective sleeve 26. The combined use of the first rotating anti-bridging knife assembly 23 and the second rotating anti-bridging knife assembly 24 can prevent the entanglement or accumulation of short fibers. The processor 1 is symmetrically equipped with support rods 41. A strip-shaped guide plate 42 is mounted on the top of the support rods 41, and an arc-shaped guide plate 43, which works in conjunction with the rotating plate 52, is mounted on the bottom of the strip-shaped guide plate 42. The arc-shaped guide plate 43 has a semi-circular design, and its groove is the same as the discharge port 54. A connecting cloth 44 is installed between the top of the strip-shaped guide plate 42 and the interior of the processor 1, through which short fibers enter the interior of the strip-shaped guide plate 42. After being processed by the anti-blocking mechanism, the short fibers are conveyed through the combined use of the strip-shaped guide plate 42 and the arc-shaped guide plate 43. The processor 1 is equipped with a discharge port 54 on its exterior, and a conveyor belt is installed inside the discharge port 54 for better transport of the processed short fibers. The processor 1 is equipped with an inlet 55 on its top. Short fibers are added to the interior of the processor 1 through the inlet 55, and the short fibers are discharged from the interior of the processor 1 through the discharge port 54. A vibrator 61 is externally mounted on the processor 1. The output shaft of the vibrator 61 extends through the processor 1 into its interior, and a vibrating plate 62 is mounted at its end. The vibrator 61 and the vibrating plate 62 work together to vibrate and lower short fibers that enter the processor 1. A first flexible cloth 63 is mounted on the top of the vibrating plate 62, and a second flexible cloth 64 is mounted on the bottom. The free ends of both the first and second flexible cloths 63 and 64 are connected to the interior of the processor 1. The cooperation of the first and second flexible cloths 63 and 64 prevents short fibers from entering the angle between the vibrating plate 62 and the vibrator 61, thus reducing the vibration force of the vibrating plate 62.

[0020] When it is necessary to use the device to pre-treat the short fibers, the short fibers are put into the interior of the processor 1 through the feed port 55, the vibrator 61 is started, the vibrator 61 drives the vibrating plate 62 to work, the vibrating plate 62 vibrates the short fibers that have entered the interior of the processor 1, so that the short fibers enter the bottom of the processor 1 by gravity. During the movement of the short fibers, the servo motor 21 is activated, which drives the rotating rod 22 to rotate. During the rotation, the rotating rod 22 pre-processes the short fibers accumulated inside the processor 1 through the cooperation of the first rotating arch-breaking knife group 23 and the second rotating arch-breaking knife group 24. At the same time, the rotating rod 22 drives the fixed ring 31 to rotate. The fixed ring 31 cuts the "arched bridge" formed by the short fibers through the cutting blade 32. During the rotation, the fixed ring 31 breaks up the short fibers between the first rotating arch-breaking knife group 23 and the fixed ring 31 and between the second rotating arch-breaking knife group 24 and the fixed ring 31 through the cooperation of the strip rod 33 and the loosening needle 34, so as to prevent the short fibers from accumulating into clumps. The cooperation of the first rotating arch-breaking knife group 23, the second rotating arch-breaking knife group 24 and the cutting blade 32 can prevent the "arched bridge" formed by the short fibers inside the processor 1 from causing blockage. After the short fibers are processed by the anti-clogging mechanism, they enter the interior of the arc-shaped guide plate 43 through the strip guide plate 42. The short fibers inside the arc-shaped guide plate 43 eventually move to the top of the rotating plate 52. The hanging motor 51 is started, and the hanging motor 51 drives the rotating plate 52 to rotate. During the rotation, the rotating plate 52 performs anti-entanglement treatment on the short fibers that have entered the strip guide plate 42. The rotating plate 52 generates centrifugal force during rotation, which separates the short fibers outside the rotating plate 52 to prevent them from connecting together and causing entanglement. The separated short fibers enter the interior of the discharge port 54 through the arc-shaped guide plate 43 and are finally discharged from the interior of the processor 1.
