Description

Technical Field

[0001] This utility model relates to the technical field of flax yarn production, and in particular to the technical field of an automatic feeding device for long flax yarn production. Background Technology

[0002] Long fibers possess numerous properties such as hygiene, comfort, coolness, moisture absorption, and antibacterial properties, making their fabrics highly sought after by modern people. Due to the limited length of natural flax, the production process of long fibers requires overlapping the combed long fibers according to specified fiber bundle specifications to form fiber strips. These fiber strips are then processed through multiple processes such as drawing, shaving, and spinning to form high-quality yarn.

[0003] In the yarn production process, raw materials need to be poured into the equipment through a feeding device. The discharge port of the existing feeding device is prone to blockage, which requires manual cleaning by the staff. This seriously affects the continuity of the feeding device, resulting in a decrease in the feeding efficiency of the feeding device and seriously affecting the production efficiency of flax yarn, thus failing to meet production needs.

[0004] To address the problems mentioned above, for example, application number CN202123230619.6 discloses an automatic feeding device for long flax in flax yarn production, including a storage box and feeding hoppers fixedly connected to both sides of the storage box. A discharge pipe is fixedly connected to the bottom of the storage box, and a clearing device is installed inside the discharge pipe. When blockage occurs at the connection between the storage box and the discharge pipe, a drive motor is activated to rotate the shaft. The rotation of the shaft causes the fixed sleeve to rotate, which in turn causes the clearing rod to rotate, facilitating the clearing rod to clear the discharge pipe and effectively preventing blockage. Furthermore, by activating a telescopic mechanism, the mounting plate moves downwards, which in turn causes the extrusion plate to move downwards, facilitating the movement of the long flax inside the storage box into the discharge pipe, effectively preventing the long flax from accumulating inside the storage box.

[0005] However, this device also has the following drawbacks:

[0006] 1. The cylindrical drain rod in the above structure is easily wrapped with fibers, forming a "snowball" blockage;

[0007] 2. Simply rotating the drain rod is not enough to effectively unclog the blockage;

[0008] 3. The vertical movement of a single extrusion plate can only apply pressure to a local area, and long hemp fibers are prone to accumulate at the edges or corners of the storage box, forming "dead corners";

[0009] 4. Hard compression may break long hemp fibers, especially hemp materials that are sensitive to humidity, which are prone to clumping and damaging the integrity of the fiber structure. Summary of the Invention

[0010] The purpose of this invention is to solve the problems in the prior art and to propose an automatic feeding device for flax yarn production. This device can cut the tangled fibers with serrated blades and disperse and accumulate them in a spiral structure, thereby effectively clearing the blockage.

[0011] To achieve the above objectives, this utility model proposes an automatic feeding device for long flax yarn production, comprising a storage box, a discharge port, a discharge tank, a spiral blade shaft, spiral blades, support legs, a support plate, a drive mechanism, and longitudinal protrusions; the inner bottom wall of the storage box is provided with a discharge port, and the outer bottom wall of the storage box is provided with a discharge tank communicating with the discharge port; the discharge tank is provided with a spiral agitation mechanism inside, which includes a spiral blade shaft and spiral blades, the spiral blade shaft being rotatably mounted inside the discharge tank, and the surface of the spiral blade shaft being provided with intermittently distributed spiral blades; several support legs are provided below the storage box, and a support plate is provided between two adjacent support legs, the support plate being provided with a drive mechanism for driving the spiral blade shaft to rotate; the inner wall of the discharge tank is provided with multiple longitudinal protrusions.

[0012] Preferably, the storage bin has a feed inlet on its side wall.

[0013] Preferably, the edges of the helical blades are serrated.

[0014] Preferably, the longitudinal ridges on the inner wall of the discharge tank form a periodic shearing fit with the outer edge of the spiral blade.

[0015] Preferably, the drive mechanism includes a drive motor, a main gear and a secondary gear. The output shaft of the drive motor is provided with a main gear at its end, and one end of the spiral blade shaft passes through the side wall of the discharge tank and is provided with a secondary gear. The secondary gear is meshed with the main gear.

[0016] Preferably, the top of the storage box is provided with a cylinder, the driving end of the cylinder is connected to a hydraulic rod through the inside of the storage box, the end of the hydraulic rod is connected to a top plate, and a plurality of intermittently distributed springs are provided below the top plate, and a pressing plate is connected to the bottom of the plurality of springs.

[0017] Preferably, scrapers are connected to both ends of the top plate, and the sidewalls of the scrapers are in close contact with the inner sidewall of the storage bin.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model sets the edges of the spiral blades in a serrated shape, so that the serrated blades can cut the entanglement of fibers and disperse the spiral structure, thereby avoiding the surface of the spiral blades from being easily wrapped by fibers, and solving the problem that the surface of the cylindrical drain rod is easily wrapped by fibers, forming a "snowball" blockage;

[0020] 2. This utility model uses the relative motion between the longitudinal convex ridges and the spiral blades to continuously scrape off the attached material, thereby effectively achieving the unblocking effect. At the same time, it realizes automatic material cleaning, eliminating the need for workers to stop the machine and manually clean the attached fibers, thus solving the problem that simply rotating the unblocking rod cannot achieve effective unblocking.

[0021] 3. This utility model connects scrapers to both ends of the top plate, so that the top plate drives the scrapers at both ends to descend synchronously during the descent process, thereby squeezing and lowering the long hemp at the edge or corner of the storage box, thus avoiding the phenomenon of long hemp residue accumulation. It solves the problem that the vertical movement of a single extrusion plate can only apply pressure to a local area, and long hemp is easy to accumulate at the edge or corner of the storage box, forming a "dead corner".

[0022] 4. This utility model, through the combined action of springs and extrusion plates, can reduce single-point pressure and reduce fiber damage through elastic buffering, thereby improving production quality. It solves the problem that hard extrusion may break long hemp fibers, especially hemp materials that are sensitive to humidity and are prone to clumping, which can damage the integrity of the fiber structure.

Detailed Implementation

[0030] See Figures 1 to 6 This utility model discloses an automatic feeding device for long flax yarn production, comprising a storage tank 1, a discharge port 101, a discharge tank 2, a spiral blade shaft 201, spiral blades 202, support legs 3, support plates 4, a drive mechanism 5, and longitudinal protrusions 203. The inner bottom wall of the storage tank 1 is provided with a discharge port 101, and the outer bottom wall of the storage tank 1 is provided with a discharge tank 2 communicating with the discharge port 101. The discharge tank 2 is provided with a spiral stirring mechanism, which includes a spiral blade shaft 201 and spiral blades 202. The spiral blade shaft 201 is rotatably mounted inside the discharge tank 2, and the surface of the spiral blade shaft 201 is provided with intermittently distributed spiral blades 202. Several support legs 3 are provided below the storage tank 1, and a support plate 4 is provided between two adjacent support legs 3. The support plate 4 is provided with a drive mechanism 5 for driving the spiral blade shaft 201 to rotate. The inner wall of the discharge tank 2 is provided with multiple longitudinal protrusions 203.

[0031] See Figure 5 The storage box 1 has a feed inlet 102 on its side wall, which allows long hemp to enter the storage box 1 through the feed inlet 102.

[0032] See Figure 2 and Figure 3 The edges of the spiral blade 202 are serrated. By setting the edges of the spiral blade 202 to be serrated, the serrated blade can cut the fiber entanglement and the spiral structure is dispersed and stacked, thereby avoiding the surface of the spiral blade 202 from being easily wrapped by fibers.

[0033] See Figure 3 The longitudinal protrusions 203 on the inner wall of the discharge tank 2 form a periodic shearing fit with the outer edge of the spiral blades 202. The relative movement between the longitudinal protrusions 203 and the spiral blades 202 continuously scrapes off the attached material, thereby effectively clearing the blockage. At the same time, it achieves automatic material cleaning, eliminating the need for workers to stop the machine and manually clean the attached fibers.

[0034] See Figure 4The driving mechanism 5 includes a drive motor 501, a main gear 502, and a secondary gear 503. The output shaft of the drive motor 501 is equipped with the main gear 502. One end of the spiral blade shaft 201 passes through the side wall of the discharge tank 2 and is equipped with the secondary gear 503. The secondary gear 503 meshes with the main gear 502. The input end of the drive motor 501 is connected to an external power source. When the drive motor 501 starts, it drives the output shaft to rotate. The output shaft drives the main gear 502 to rotate, the main gear 502 drives the secondary gear 503 to rotate, the secondary gear 503 drives the spiral blade shaft 201 to rotate, and the spiral blade shaft 201 drives the spiral blade 202 to rotate, thereby clearing the discharge tank 2 and allowing the cleared long hemp to enter the equipment through the discharge port (not shown in the figure) below the discharge tank 2.

[0035] See Figure 5 The top of the storage box 1 is equipped with a cylinder 6. The driving end of the cylinder 6 passes through the inside of the storage box 1 and is connected to a hydraulic rod 7. The end of the hydraulic rod 7 is connected to a top plate 8. A plurality of intermittently distributed springs 9 are provided below the top plate 8. A pressing plate 10 is connected to the bottom of the plurality of springs 9. The input end of the cylinder 6 is connected to an external power source. When the cylinder 6 is started, it drives the hydraulic rod 7 to descend. The hydraulic rod 7 drives the top plate 8 to descend. The top plate 8 drives the pressing plate 10 to descend, which facilitates the movement of the long hemp inside the storage box 1 to the discharge tank 2. This can effectively prevent the long hemp from accumulating inside the storage box 1. At the same time, the elastic cushioning reduces fiber damage, thereby improving production quality.

[0036] See Figure 5 The top plate 8 is connected to two ends of scrapers 81. The sidewalls of the scrapers 81 are in close contact with the inner sidewall of the storage box 1. By connecting scrapers 81 to both ends of the top plate 8, the top plate 8 drives the scrapers 81 at both ends to descend synchronously during the descent process, thereby squeezing and lowering the long hemp at the edge or corner of the storage box 1, thus avoiding the accumulation of long hemp residue.

[0037] The working process of this utility model:

[0038] This utility model discloses an automatic feeding device for long flax in flax yarn production. During operation, the long flax first enters the storage tank 1 through the feed inlet 102. Then, the cylinder 6 drives the hydraulic rod 7 to descend, which in turn drives the top plate 8 to descend. The top plate 8 then drives the extrusion plate 10 to descend, facilitating the movement of the long flax inside the storage tank 1 to the discharge tank 2. This effectively prevents the long flax from accumulating inside the storage tank 1. When a blockage occurs at the connection between the storage tank 1 and the discharge tank 2, the drive motor 501 drives the output shaft to rotate. The output shaft drives the main gear 502 to rotate, which in turn drives the secondary gear 503 to rotate. The secondary gear 503 drives the spiral blade shaft 201 to rotate, which in turn drives the spiral blade 202 to rotate. This clears the blockage in the discharge tank 2, allowing the cleared long flax to enter the equipment through the discharge port (not shown in the figure) below the discharge tank 2.

[0039] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
