Abstract
Description
Technical Field
[0001] The utility model relates to a fiber opening device, and more specifically, to an opening device. Background Art
[0002] The opener is one of the commonly used devices in the textile industry, mainly used to loosen the pressed and entangled fiber raw materials and remove impurities for subsequent textile processing. Common opening methods include tearing opening, beating opening, and cutting opening. Tearing opening is to tear the fibers through two needle plates with opposite moving directions to complete the opening. For an opener that uses the tearing principle to achieve opening, a common structure includes a spike lath and a spike roller. Spike plates or spike strips are provided on the spike lath and the spike roller, and spikes are provided on the spike plates and the spike strips. The spike lath is used to convey fibers, and during the conveying process, it interacts with the spike roller to tear the fibers to complete the opening. In order to achieve a good tearing effect, there is a certain inclination angle between the spike and the plate or strip on which the spike is installed. This angle needs to meet the requirements of fiber tearing and at the same time ensure that the fibers can smoothly separate from the spike plate and spike strip after tearing. According to different types of fibers, the optimal inclination angle is also different. For example, for cotton fibers, the required angle is usually between 30° and 45°, and for wool fibers, it is usually between 45° and 60°. In the prior art, the spikes are fixed to the spike plates or spike strips, and when the fibers opened by the opener change from wool to cotton, it is necessary to replace the spike lath or the spike roller. Therefore, the manufacturer needs to keep two types of spike laths or spike rollers in stock, and when replacing, it is necessary to open the machine shell, disassemble and reinstall, and the operation is not convenient.

[0027] Embodiment:
[0028] A loosening device, the loosening device includes a spike curtain 2 and a spike roller 1. Chains are arranged on both sides of the spike curtain 2; the chains are engaged with the first sprockets; a second sprocket is arranged on the spike roller 1; the first sprocket and the second sprocket are driven by a driving motor. The spike curtain 2 completes a circular motion through the chains. When the spike curtain 2 moves at the position of the spike roller 1, the spike curtain 2 is located below the spike roller 1; at this time, the moving direction of the spike curtain 2 is opposite to the moving direction of the spike roller 1. Spike plates 3 are arranged on the spike curtain 2 and the spike roller 1; a row of spikes with the same spacing are arranged on the spike plates 3; the spikes on the spike curtain 2 and the spike roller 1 are staggered and aligned. When in use, the spikes on the spike roller 1 pass through between the spikes on the spike curtain 2, and the fibers on the spikes are torn by the spikes on the spike roller 1 to complete loosening.
[0029] In this embodiment, the spike plate 3 includes a base plate 31, an adjusting plate 32 and spikes 5; a fixing rod is arranged on the base plate 31, and a fixing groove 42 is arranged on the fixing rod; a fixing hole is arranged at the tail of the spike, and the spike 5 is sleeved in the fixing groove 42 through the fixing hole; a spike hole 321 is arranged on the adjusting plate 32; the spike passes through the spike hole 321; the adjusting plate 32 is slidably connected to the base plate 31; by adjusting the relative position of the base plate 31 and the adjusting plate 32, the inclination angle of the spike and the spike plate 3 is adjusted. When the inclination angle of the spike needs to be adjusted, the user can change the included angle between the spike and the base plate 31 by moving the position of the adjusting plate 32 relative to the base plate 31. Since the tail of the spike is fixed in the fixing groove 42, and the head of the spike passes through the spike hole 321 on the adjusting plate 32, the movement of the adjusting plate 32 will drive the change of the inclination angle of the spike. Through this solution, the inclination angle of the spike can be reasonably adjusted according to the type of fiber, so that the device can better adapt to different fiber types. By adopting this solution, there is no need to replace the entire spike plate 3 or the roller, which improves the adaptability and flexibility of the equipment. At the same time, the adjustment process is simple and fast, reducing the maintenance cost and production time.
[0030] In a possible embodiment, the fixing rod is columnar; a limiting sleeve is sleeved on the fixing rod; the diameter of the fixing hole matches the diameter of the fixing rod; the limiting sleeve is arranged between the spikes. The setting of the limiting sleeve limits the lateral movement of the spike in the fixing groove 42, preventing the spike from loosening or falling off due to vibration during high-speed operation. At the same time, the limiting sleeve also plays a buffering role, reducing the friction and wear between the spike and the fixing rod. Preferably, the limiting sleeve is made of a magnetic material. On the one hand, it can better fix the spike. On the other hand, after the magnetic field of the magnetic material is transmitted to the spike, some iron impurities can be adsorbed by the spike through the spike, improving the quality of loosening.
[0031] In a possible embodiment, the corner nails are sheet-shaped; the corner nail holes 321 are adapted to the sheet-shaped corner nails; the corner nail holes 321 form an angle of 30 to 45 degrees with the adjusting plate 32; the thickness of the corner nail holes 321 is adapted to the thickness of the corner nails; the width of the corner nail holes 321 is slightly wider than that of the corner nails; the width of the corner nail holes 321 is 10% to 30% more than that of the corner nails. Through the above solution, when adjusting the adjusting plate 32 and the substrate 31, the corner nails can smoothly change the angle; the angle between the corner nail holes 321 and the adjusting plate 32 determines the minimum inclination angle of the corner nails; the width of the corner nail holes 321 determines the maximum inclination angle that the corner nails can tilt. Through the above solution, the corner nails can be in two gears of the maximum inclination angle and the inclination angle of the corner nail holes 321. Furthermore, it can respectively adapt to two different types of fiber products, namely wool fibers and cotton fibers. Preferably, chamfers are provided on the front and rear sides of the corner nail holes 321. Since the corner nails will slide relative to the corner nail holes 321 when adjusting the angle, the sliding can be better achieved by providing chamfers. During use, if there is a jamming phenomenon, manual assistance can be provided to make the adjustment in place.
[0032] In a possible embodiment, threaded holes 311 are provided at both ends of the substrate 31; an adjusting groove is provided on the adjusting plate 32; a fixing bolt 312 is further included; the fixing bolt 312 connects the adjusting groove and the threaded hole 311 to connect the adjusting plate 32 and the substrate 31. When the angle of the corner nails needs to be adjusted, the fixing bolt 312 can be loosened, the adjusting plate 32 can be moved to the required position, and then the fixing bolt 312 can be tightened again. The rotational movement of the fixing bolt 312 in the threaded hole 311 is converted into the relative sliding movement between the adjusting plate 32 and the substrate 31, thereby realizing the adjustment of the angle of the corner nails. In a possible embodiment, two second threaded holes 311 are provided on the adjusting plate 32, and the two second threaded holes 311 respectively correspond to the minimum inclination angle and the maximum inclination angle of the corner nails.
[0033] In a possible embodiment, a bolt groove 322 is further provided on the adjusting plate 32; the adjusting groove is arranged in the bolt groove 322. The depth of the bolt groove 322 is adapted to the head height of the fixing bolt 312. When the fixing bolt 312 is tightened, the fixing bolt 312 sinks into the bolt groove 322, and fibers are not easily caught on the fixing bolt 312 during use.
[0034] In other possible embodiments, the fixing rod is a cylinder, including a first cylinder 41 and a second cylinder; the first cylinder 41 and the second cylinder are arranged at intervals; the diameter of the second cylinder is smaller than that of the first cylinder 41; two adjacent first cylinders 41 and the second cylinder together form a fixing groove 42; the fixing hole includes a first hole body 51 and a second hole body 52, and both the first hole body 51 and the second hole body 52 are circular holes; the diameter of the first hole body 51 matches the diameter of the first cylinder 41; the diameter of the second hole body 52 matches the diameter of the second cylinder; the first hole body 51 and the second hole body 52 are connected by a connecting portion. When the corner nail is sleeved in the fixing groove 42 through its fixing hole, the first hole body 51 is sleeved on the first cylinder 41 to play a main fixing role; the second hole body 52 is sleeved on the second cylinder to play an auxiliary fixing and limiting role. Through the above solution, when it is necessary to install the corner nail, one end of the first hole body 51 is sleeved on the first cylinder 41, and the corner nail moves on the fixing rod. When it moves to the second cylinder, the corner nail is put down, and the second hole body 52 cooperates with the second cylinder to realize the support of the corner nail. Through the above solution, the fixing of the corner nail is made more firm and reliable and is easy to install and disassemble. At the same time, due to the existence of the second cylinder, it also plays a limiting role, preventing the occurrence of excessive shaking and falling off of the corner nail during high-speed operation.
[0035] In other possible embodiments, a rubber limiting pad 323 is arranged in the corner nail hole 321; the rubber limiting pad 323 increases the friction between the corner nail hole 321 and the corner nail, avoiding the displacement between the corner nail and the corner nail hole 321 when the corner nail is at a large angle and facing downwards.
[0036] In other possible embodiments, an installation groove is arranged on the substrate 31, and the fixing rod is arranged in the installation groove. Through the above solution, the fiber is prevented from winding around the fixing rod.
[0037] The beneficial effects of this embodiment: Through the staggered alignment design of the corner nail curtain and the corner nail roller, when the corner nails on the corner nail roller pass between the corner nails of the corner nail curtain, the fiber can be effectively torn, realizing efficient opening. This mechanical action method improves the opening efficiency of the fiber and provides a good fiber state for subsequent textile processing.
[0038] By adjusting the relative positions of the substrate and the adjusting plate, the inclination angle of the corner nail can be easily changed to adapt to different types of fibers (such as wool fibers and cotton fibers), enhancing the flexibility and adaptability of the equipment.
[0039] The process of adjusting the corner nail angle is simple and fast, without the need to replace the entire corner nail plate or roller, reducing the maintenance cost and production time. This modular design makes maintenance more convenient and improves the production efficiency.
[0040] The setting of the limit sleeve not only restricts the lateral movement of the corner nails in the fixing groove, prevents the corner nails from loosening or falling off during high-speed operation, but also plays a buffering role, reducing the friction and wear between the corner nails and the fixing rod. At the same time, the limit sleeve is made of magnetic material, further enhancing the fixing effect and capable of adsorbing some iron impurities to improve the loosening quality.
[0041] The angle design of the corner nail holes and the adjusting plate, as well as the width adjustment of the corner nail holes, enable the corner nails to be precisely adjusted within a predetermined angle range to meet the requirements of different fiber types. This precise control helps to optimize the loosening effect and improve the product quality.
[0042] By setting the installation groove on the substrate and placing the fixing rod in the installation groove, the problem of fiber winding on the fixing rod is effectively avoided, reducing the failures and maintenance work caused by fiber winding.
[0043] A rubber limit pad is arranged in the corner nail hole, increasing the friction between the corner nail hole and the corner nail, preventing the corner nail from displacing when facing downwards, and at the same time improving the wear resistance of the corner nail hole and the corner nail, extending the service life of the equipment.
[0044] The fixing design of the corner nails makes the installation and disassembly process more simple and fast. Through the cooperation of the fixing holes and the fixing grooves, and the sliding connection between the adjusting plate and the substrate, users can easily complete the replacement and maintenance work of the corner nails.
[0045] This specific embodiment is only an explanation of the present utility model, and it is not a limitation of the present utility model. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
