Description

Technical Field

[0001] The present invention relates to the field of the structure of a bale opener, and particularly to a bale opener for preventing cotton jamming. Background Art

[0002] The main function of a bale opener is to loosen and remove impurities from the compacted and entangled fiber raw materials, so as to provide qualified fiber raw materials for subsequent textile processing procedures. Traditional bale openers usually adopt simple mechanical structures and loosen cotton fibers through beaters or needles. However, in traditional bale openers, when the beaters and needles of the loosening device loosen the fiber raw materials, due to the large frictional force between the fibers, they are extremely easy to entangle with each other. When the fibers are wound around the beaters or needles, they will gradually form lumps, hindering the normal transportation and loosening of the fibers, and ultimately resulting in the phenomenon of cotton jamming, thereby affecting the working efficiency and product quality of the bale opener. Summary of the Invention

[0024] Refer to Figures 1-5, A carding-free opener, comprising a frame 1, a cabin 2, a feeding component 3, a discharging component 4, an opening device 5, a pre-opening component 6, a conveying component 7 and a blowing component 8. The frame 1 provides support and an installation foundation for the entire opener. There is a cabin 2 on the frame 1. The cabin 2 can provide a closed working space for the various components of the opener, prevent fibers and impurities from scattering, and at the same time protect the safety of the operators. There is a feeding port on one side of the cabin 2 and a discharging port on the other side. Inside the cabin 2 near the feeding port, there is a feeding component 3, which can evenly and stably convey the fiber raw materials to be opened to the subsequent processes. Inside the cabin 2 near the discharging port, there is a discharging component 4, which can collect the fibers after the opening treatment and output them. Between the feeding component 3 and the discharging component 4, there is an opening device 5, which can perform deep opening treatment on the fiber raw materials. Between the opening device 5 and the feeding component 3, there is a pre-opening component 6, which can perform preliminary opening on the fiber raw materials conveyed by the feeding component 3, reduce the working burden of the opening device 5, and improve the overall opening efficiency. Between the pre-opening component 6 and the opening device 5, there is a conveying component 7, which can smoothly convey the pre-opened fibers to the opening device 5. Inside the cabin 2, there is also a blowing component 8. The blowing component 8 is connected to the opening device 5, and the blowing direction of the blowing component 8 is towards the discharging component 4, which can use the airflow to quickly convey the opened fibers to the discharging component 4, prevent the fibers from accumulating in the opening device 5, and reduce the occurrence of carding phenomenon.

[0025] In some embodiments, the pre-opening component 6 includes a rotating roller 61 and a plurality of first beaters 62. The rotating roller 61 is rotatably installed between the feeding component 3 and the pre-opening component 6. The rotating roller 61 can be connected to an external rotating motor. A plurality of first beaters 62 are evenly distributed on the rotating roller 61. When the rotating roller 61 rotates, the plurality of first beaters 62 rotate accordingly, performing pre-opening on the materials conveyed on the feeding component 3, initially loosening the fiber raw materials, and preparing for the subsequent opening treatment. By adjusting the rotation speed of the rotating roller 61 and the distribution density of the first beaters 62, the pre-opening effect can be controlled.

[0026] In some embodiments, the conveying assembly 7 includes a first conveying roller 71 and a second conveying roller 72. The first conveying roller 71 is rotatably arranged between the pre-opening assembly 6 and the opening device 5 and can be connected to an external rotating motor. Above the first conveying roller 71, there is a second conveying roller 72 which can be connected to an external rotating motor. The rotation direction of the first conveying roller 71 is opposite to that of the second conveying roller 72, and the rotation speed of the first conveying roller 71 is greater than that of the second conveying roller 72. The rotation of the first conveying roller 71 and the second conveying roller 72 can form a speed difference, thereby generating two acting forces on the fiber with different magnitudes and opposite directions, so as to exert a certain stretching effect on the fiber, making the fiber looser during the conveying process, facilitating subsequent opening treatment, and at the same time ensuring the stable conveyance of the fiber to the opening device 5, and avoiding the accumulation of fiber during the conveying process resulting in cotton jamming.

[0027] In some embodiments, the opening device 5 includes an opening chamber 51, an opening rotating shaft 52, a positioning end cover 53, a locking end cover 54 and a plurality of opening assemblies 55. The opening chamber 51 is connected to the discharging assembly 4, the conveying assembly 7 and the air blowing assembly 8 to form a relatively enclosed processing space. Inside the opening chamber 51, there is a rotatable opening rotating shaft 52 which can be connected to an external motor to realize the rotation of the opening rotating shaft 52. One end of the opening rotating shaft 52 is provided with a positioning end cover 53, and the rotation connection between one end of the opening rotating shaft 52 and the engine room 2 can be realized through the positioning end cover 53 and the bearing. The other end of the opening rotating shaft 52 is provided with a locking end cover 54, and the rotation connection between the other end of the opening rotating shaft 52 and the engine room 2 can be realized through the locking end cover 54 and the bearing. There are at least two opening assemblies 55 between the positioning end cover 53 and the locking end cover 54. The rotation of the opening rotating shaft 52 can drive the rotation of the opening assemblies 55, thereby deeply opening the cotton fiber. The locking end cover 54 is detachably connected to the opening rotating shaft 52, which can be connected by thread or by a bolt assembly. Through the locking end cover 54, the installation and disassembly of the plurality of opening assemblies 55 and the opening rotating shaft 52 can be realized, so as to facilitate the installation, disassembly and maintenance of the opening assemblies 55. A positioning ring is provided on one side of the positioning end cover 53 close to the locking end cover 54 and on one side of the opening assembly 55 close to the locking end cover 54. A positioning groove is provided on one side of the opening assembly 55 and the locking end cover 54 close to the positioning end cover 53. The positioning ring and the positioning groove are inserted and matched, which can facilitate the pre-positioning during the installation of the opening assembly 55, thereby improving the installation convenience and installation accuracy.

[0028] In some embodiments, the opening component 55 includes a fixed ring 551, a plurality of second beaters 552, and a plurality of thorn needles 553. The fixed ring 551 is coaxially sleeved on the opening rotating shaft 52. A plurality of second beaters 552 are provided on the fixed ring 551, and a plurality of thorn needles 553 are equidistantly arranged between two adjacent second beaters 552. When the opening rotating shaft 52 rotates, it drives the fixed ring 551, the second beaters 552, and the thorn needles 553 to rotate. The coordinated action of the beaters and the thorn needles performs a multi-level and multi-angle opening treatment on the cotton fibers to ensure the opening effect.

[0029] Specifically, when the opening rotating shaft 52 rotates around its own axis, it will synchronously drive the fixed ring 551 to perform a circular motion. The plurality of second beaters 552 installed on the fixed ring 551 will rotate together with the fixed ring 551. During the rotation, the second beaters 552 can generate a first striking force on the cotton fiber raw material entering the opening chamber 51. When the second beaters 552 rotate at high speed, they use their own mass and rotational speed to apply a large impact force on the cotton fiber raw material, initially dispersing the originally tightly entangled cotton fiber mass. After that, the cotton fiber raw material contacts the plurality of thorn needles 553. With its sharp structure, the thorn needles 553 can penetrate into the interior of the cotton fibers and separate the intertwined fiber bundles. Since the second beaters 552 and the thorn needles 553 are staggered in the circumferential direction on the fixed ring 551, after being struck by the second beaters 552, the cotton fibers will immediately enter the action range of the thorn needles 553. The striking force of the second beaters 552 and the carding force of the thorn needles 553 cooperate with each other to open the cotton fibers from different angles and levels. The second beaters 552 macroscopically disperse the cotton fiber mass, turning the cotton fiber mass into smaller fiber bundles; while the thorn needles 553 card the fiber bundles from the microscopic level, separating the single fibers in the fiber bundles, thereby realizing a multi-level and multi-angle opening treatment of the cotton fibers, effectively ensuring the opening effect, and providing high-quality fiber raw materials for subsequent textile processes.

[0030] In some embodiments, in order to enhance the cleaning effect, an air vent cavity 56 is provided between the fixed ring 551 and the opening shaft 52. A connection groove 531 is provided on the positioning end cap 53 close to the opening assembly 55. The connection groove 531 is connected to the air vent cavity 56. A plurality of connection holes 532 are provided on the positioning end cap 53. The connection holes 532 are connected to the connection groove 531. An air vent ring 57 is sleeved on the positioning end cap 53. The air vent ring 57 is connected to an external air supply device (such as a blower) and can convey gas into the opening assembly 55 to achieve the cleaning of the opening assembly 55 and reduce the phenomenon of cotton jamming. The air vent ring 57 is rotationally and sealingly connected to the positioning end cap 53, and can be rotationally and sealingly connected through a sealing ring. This can ensure that no gas leakage occurs between the air vent ring 57 and the positioning end cap 53 during the rotation of the opening shaft 52 driving the positioning end cap 53 and the opening assembly 55, and can also allow the positioning end cap 53 to rotate smoothly relative to the air vent ring 57, thus not affecting the normal operation of the opener. An air vent groove 571 is provided in the air vent ring 57, and a plurality of connection holes 532 are provided in the air vent groove 571. A plurality of exhaust holes 554 are provided on the fixed ring 551, and the exhaust holes 554 are connected to the air vent cavity 56.

[0031] Specifically, the external air supply device conveys compressed air into the ventilation ring 57, and through the ventilation groove 571. The compressed air entering the ventilation groove 571 will smoothly enter the connection groove 531 through the connection hole 532, and then enter the ventilation cavity 56. The compressed air entering the ventilation cavity 56 will be discharged through a plurality of exhaust holes 554 provided on the fixed ring 551, thereby forming an air flow around the opening and loosening assembly 55, and forming an air curtain around the second beater 552 and the thorn needles 553. When the cotton fibers that have not been processed by the thorn needles 553 pass through this air curtain, the aerodynamic force of the air curtain is less than the connection force between the cotton fibers, so as to ensure that the cotton fibers passing through the second beater 552 come into normal contact with the thorn needles 553, realizing the opening and loosening of the cotton fibers. When the cotton fibers passing through the thorn needles 553 approach, the aerodynamic force of the air curtain is greater than the connection force between the cotton fibers and the frictional force between the cotton fibers and the thorn needles 553, and the air flow will change the movement trajectory of the fibers, making them move away from the second beater 552 and the thorn needles 553, preventing the opened and loosened cotton fibers from directly contacting and winding around the second beater 552 and the thorn needles 553, realizing the self-cleaning of the opening and loosening assembly 55, and thus ensuring the smooth progress of the opening and loosening work. At the same time, the air flow following the rotation of the opening and loosening rotating shaft 52 cooperates with the air blowing assembly 8, which can strengthen the turbulent flow effect in the opening and loosening cavity 51, thereby accelerating the separation of impurities such as dust and short lint from the cotton fibers in the opening and loosening cavity 51, effectively reducing the accumulation of impurities near the opening and loosening assembly 55, and improving the cleanliness inside the opening and loosening machine. Moreover, the continuous air flow can also take away the heat generated by the opening and loosening assembly 55 during operation, playing a certain role in dissipating heat for the opening and loosening assembly 55, helping to extend the service life of the opening and loosening assembly 55, and ensuring the stable operation of the opening and loosening machine. At the same time, the air flow in the opening and loosening cavity 51 can be ejected from the connection between the positioning end cover 53, the locking end cover 54 and the plurality of opening and loosening assemblies 55, which can prevent the cotton fibers from adhering to the connection, and avoid the influence of the detachable structure of the opening and loosening device 5 on the opening and loosening process.

[0032] In some embodiments, in order to ensure the stability and maintainability of the opening and loosening assembly 55, a plurality of fixing plates 58 are provided on the opening and loosening rotating shaft 52, and a plurality of positioning grooves are provided on the inner wall of the fixed ring 551. The positioning grooves are inserted and matched with the fixing plates 58 to realize the positioning and installation of the fixed ring 551 on the opening and loosening rotating shaft 52, and a plurality of communication holes are provided on the fixing plates 58 to ensure the smooth flow of the gas in the ventilation cavity 56.

[0033] In some embodiments, a dust cage 9 is provided at the bottom of the opening and loosening cavity 51, and a waste discharge port is provided at the bottom of the dust cage 9. During the opening and loosening process, the impurities in the fiber raw materials fall into the dust cage 9 under the action of gravity and air flow, and are discharged through the waste discharge port, realizing the effective cleaning of the impurities and reducing the phenomenon of cotton jamming caused by the accumulation of impurities.

[0034] In some embodiments, the discharging assembly 4 includes two rotatable discharging rollers 41, and the two discharging rollers 41 are drivingly connected by a discharging conveyor belt 42 to achieve the discharging of cotton fibers. The feeding assembly 3 includes two rotatable feeding rollers 31, and the two feeding rollers 31 are drivingly connected by a feeding conveyor belt 32 to achieve the stable feeding of fiber raw materials.

[0035] In some embodiments, the air blowing assembly 8 may include a blower and an air blowing pipe. The air outlet of the blower is connected to the loosening chamber 51 through the air blowing pipe, and the air blowing direction of the blower faces the discharging assembly 4.

[0036] The specific working principle is as follows: After the equipment is debugged normally, the fiber raw materials to be loosened are placed on the feeding assembly 3. Under the action of the feeding rollers 31 and the feeding conveyor belt 32, the fiber raw materials are evenly conveyed to the pre-loosening assembly 6. The rotating roller 6 and the first beater 62 of the pre-loosening assembly 6 perform preliminary loosening on the fiber raw materials. The preliminarily loosened fibers are conveyed to the loosening device 5 through the conveying assembly 7. During this process, the first conveying roller 71 and the second conveying roller 72 further loosen the fibers by using the speed difference. The cotton fibers enter the loosening chamber 51, and the loosening rotating shaft 52 of the loosening device 5 drives the second beater 552 and the thorn needles 553 to rotate to perform deep loosening on the fibers. At the same time, the air blowing assembly 8 blows air into the loosening chamber 51 to convey the loosened fibers to the discharging assembly 4. The loosened and cleaned cotton fibers are discharged through the discharging assembly 4 and enter the subsequent processes. During the loosening process, the impurities fall into the dust cage 9 under the action of gravity and air flow and are discharged through the impurity discharge port.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
