Abstract
Description
Technical Field
[0001] This utility model relates to a cotton fabric opening device. Background Technology
[0002] Cotton fabric opening devices are widely used equipment in the textile and filling material manufacturing industry. Their main function is to open up compressed or clumped cotton fibers, restoring them to a fluffy state for easier subsequent processing. They are generally divided into beating and stretching. Beating utilizes free-flowing beating to generate vibrations, loosening the fiber clumps; stretching utilizes pulling to increase the volume. Compared to beating, stretching provides a better opening effect.
[0003] A common loosening method involves two parts with pins and needles on their surfaces moving relative to each other. As the parts move away from each other, the pins hook onto the cotton ball, causing the cotton ball to expand in two opposite directions.
[0004] Because common opening devices for stretching have limited pulling directions (they can only pull the cotton in two opposite directions), the cotton can only expand in two different directions. The cotton fibers are interwoven and have a complex texture, so after being opened by common stretching devices, the cotton cannot achieve the optimal degree of expansion, which may affect subsequent production and processing.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0043] Please see Figures 1-6 As one embodiment of the present utility model, the cotton fabric opening device includes a support frame 1;
[0044] The support frame 1 is equipped with a hopper 2, a protective shell 3, and a motor 4.
[0045] The support frame 1 is provided with a cooperating spreading structure, a conveying structure, and an opening structure;
[0046] The opening structure includes multiple sets of symmetrically arranged swing rods 15; the swing rods 15 can reciprocate up and down to move closer to or away from the support frame 1;
[0047] During the descent, multiple sets of swing rods 15 can swing, and the swing directions of the symmetrical swing rods 15 are opposite to drive the cotton to expand; during the ascent, the spreading structure can spread the cotton ball in the hopper 2 towards the conveying structure; and the conveying structure can transport the spread cotton to directly below the opening structure.
[0048] In this embodiment, the hopper 2 is funnel-shaped, allowing operators to easily feed cotton raw materials into it. The protective shell 3 prevents cotton from splashing everywhere during the opening mechanism's operation, thereby reducing production losses and maintaining a clean production environment. The motor 4 drives the spreading structure, conveying structure, and opening mechanism.
[0049] During use, the operator puts the cotton blank into the feed hopper 2, and the spreading structure processes the clump of cotton into a flat shape to facilitate the subsequent opening structure to open the cotton, which helps to improve the fluffiness (volume change) after opening.
[0050] At the same time, the conveying structure will transport the flat cotton directly below the opening structure.
[0051] Once the flat cotton reaches directly beneath the opening structure, the swing rod 15 descends vertically into the cotton to insert itself. At the end of its stroke, the swing rod 15 rapidly oscillates in opposite directions, pulling the cotton outwards from the inside, thus creating a fluffing effect. Because the swing rod 15 rotates, the direction of the force acting on the cotton changes continuously, causing the cotton to expand in multiple directions, thereby improving the opening efficiency. During this process, the spreading and conveying structures remain stationary.
[0052] Then the swing arm 15 will move upward to complete the reset. During this process, the spreading structure and the conveying structure will start to operate again to convey the cotton that has been opened and to convey another batch of cotton to the opening structure.
[0053] By coordinating the spreading, conveying, and opening structures, the cotton can be opened rhythmically. Furthermore, the symmetrical swing rods 15 pull the cotton from multiple directions, causing it to expand in multiple directions, thereby improving opening efficiency and fluffiness.
[0054] As a further embodiment of this utility model, a first rotating shaft 5 and a second rotating shaft 6 are rotatably mounted on the protective shell 3. A half gear 501 is mounted on the first rotating shaft 5, and a full gear 601 that meshes with the half gear 501 is mounted on the second rotating shaft 6. The first rotating shaft 5 is connected to the output end of the motor 4 by a belt. A first bevel gear 502 is mounted on the first rotating shaft 5.
[0055] In this embodiment, when the motor 4 rotates, it will drive the first rotating shaft 5 to rotate, thereby driving the half gear 501 and the first bevel gear 502 to rotate. The first bevel gear 502 is connected to the opening and closing structure, so when the first bevel gear 502 rotates, the opening and closing structure is activated.
[0056] When the half gear 501 rotates, it intermittently meshes with the full gear 601, thereby causing the full gear 601 to rotate intermittently, which in turn causes the second rotating shaft 6 to rotate intermittently. When the second rotating shaft 6 rotates, it can drive the spreading structure and the conveying structure to move.
[0057] When the first rotating shaft 5 rotates to activate the opening and closing mechanism, causing the rocker arm 15 to move downwards and deflect, the half gear 501 and the full gear 601 do not mesh, and the spreading and conveying structures do not operate. However, when the first rotating shaft 5 rotates to activate the opening and closing mechanism, causing the rocker arm 15 to move upwards and reset, the half gear 501 and the full gear 601 mesh, and the spreading and conveying structures operate.
[0058] By coordinating the spreading, conveying, and opening structures, the cotton can be opened rhythmically. Furthermore, the symmetrical swing rods 15 pull the cotton from multiple directions, causing it to expand in multiple directions, thereby improving opening efficiency and fluffiness.
[0059] As a further embodiment of this utility model, the spreading structure includes multiple sets of third rotating shafts 8 rotatably installed inside the hopper 2; and the multiple sets of third rotating shafts 8 are symmetrically arranged, with large gears 801 installed on each third rotating shaft 8, the symmetrically arranged large gears 801 meshing with each other, rollers 802 installed on each third rotating shaft 8, and multiple sets of conical protrusions 803 installed on each roller 802; one of the third rotating shafts 8 is connected to the second rotating shaft 6 by a belt.
[0060] In this embodiment, the rotation of the second rotating shaft 6 drives the rotation of a third rotating shaft 8, which in turn drives the other third rotating shaft 8 to rotate in opposite directions through the meshing of two large gears 801, so that the rollers 802 rotate synchronously. The two rollers 802 rotate in the direction of the other roller 802, and the multiple conical protrusions 803 rotate.
[0061] The conical protrusion 803 increases the friction coefficient of the roller 802, causing the cotton to move between the two rollers 802 when it comes into contact with the cotton ball. After being squeezed between the rollers 802, the cotton becomes a flat piece of cotton and falls directly onto the conveyor structure.
[0062] By spreading out the structure, the clumps of cotton are processed into flat cotton that is easy to open, thereby improving the fluffiness after opening.
[0063] As a further embodiment of this utility model, the conveying structure includes multiple sets of belt rollers 7 rotatably mounted on the support frame 1, the multiple sets of belt rollers 7 being connected by a conveyor belt 10, and one of the belt rollers 7 being connected to the second rotating shaft 6 by a belt.
[0064] In this embodiment, when one roller 7 rotates, it drives the remaining rollers 7 to rotate via the conveyor belt 10. The conveyor belt 10 receives the spread cotton and transports it directly below the opening structure, thereby improving the opening efficiency.
[0065] By coordinating the spreading, conveying, and opening structures, the cotton can be opened rhythmically. Furthermore, the symmetrical swing rods 15 pull the cotton from multiple directions, causing it to expand in multiple directions, thereby improving opening efficiency and fluffiness.
[0066] As a further embodiment of this utility model, the opening structure further includes a fixing plate 14 installed on the protective shell 3. Multiple sets of telescopic sleeves 1401 slidably connected to the swing rod 15 are installed on the fixing plate 14. A lifting plate 13 is slidably installed on the protective shell 3. Multiple sets of telescopic columns 1301 slidably engage with the telescopic sleeves 1401 on the lifting plate 13. The swing rod 15 is rotatably connected to the telescopic columns 1301. The telescopic sleeves 1401 are equipped with... An inclined rod 1402 is inclined, and a tension spring 16 fixedly connected to the swing rod 15 is installed on the inclined rod 1402; a lifting sleeve 12 is installed on the lifting plate 13, and a protruding column 1201 is installed inside the lifting sleeve 12; a fourth rotating shaft 11 is rotatably installed on the protective shell 3, and a second bevel gear 1101 that meshes with the first bevel gear 502 is installed on the fourth rotating shaft 11; a lifting groove is opened on the fourth rotating shaft 11 that slides and engages with the protruding column 1201.
[0067] As a further embodiment of this utility model, the lifting groove includes a first inclined groove 1102 and a second inclined groove 1103, one end of the first inclined groove 1102 is connected to one end of the second inclined groove 1103, and the other end of the second inclined groove 1103 is connected to the other end of the first inclined groove 1102.
[0068] In this embodiment, when the first bevel gear 502 rotates, it will drive the second bevel gear 1101 to rotate through meshing, thereby driving the fourth rotating shaft 11 to rotate, and thus driving the lifting groove to rotate synchronously.
[0069] When the protruding column 1201 slides in the first inclined groove 1102, the mutual compression between the first inclined groove 1102 and the protruding column 1201 drives the lifting sleeve 12 to move closer to the conveyor belt 10, thereby driving the lifting plate 13 to move synchronously, so as to drive the telescopic column 1301 to slide inward in the telescopic sleeve 1401, thereby driving the swing rod 15 to slide outward in the telescopic sleeve 1401, stretching the tension spring 16, so that the swing rod 15 can be vertically inserted into the cotton. When the swing rod 15 is fully exposed in the telescopic sleeve 1401, under the elastic force of the tension spring 16, the swing rod 15 will swing rapidly in the direction of the inclined rod 1402 to pull the cotton; by pulling the cotton from multiple directions with symmetrical swing rods 15, the cotton expands and enlarges in multiple directions, thereby improving the opening efficiency and fluffiness.
[0070] When the protruding column 1201 slides in the second inclined groove 1103, the mutual compression between the second inclined groove 1103 and the protruding column 1201 can drive the lifting sleeve 12 away from the conveyor belt 10, thereby driving the lifting plate 13 to move synchronously, which in turn drives the telescopic column 1301 to slide outward in the telescopic sleeve 1401, thereby pulling the swing arm 15. After being pulled, the swing arm 15 will quickly change from an inclined state to a vertical state, and after becoming vertical, it will slide inward in the telescopic sleeve 1401 to complete the reset.
[0071] Furthermore, when the protruding column 1201 slides in the first inclined groove 1102, the half gear 501 and the full gear 601 do not mesh; when the protruding column 1201 slides in the second inclined groove 1103, the half gear 501 and the full gear 601 mesh; through the cooperation of the spreading structure, the conveying structure and the opening structure, the cotton can be opened rhythmically, thereby improving the opening efficiency.
[0072] As a further embodiment of this utility model, a teardrop-shaped protrusion 1501 is installed on one end of the swing arm 15 near the conveyor belt 10.
[0073] In this embodiment, the teardrop-shaped protrusion 1501 can prevent the cotton from separating from the swing arm 15 when the swing arm 15 deflects, and can also prevent the swing arm 15 from completely hooking the cotton, thereby preventing the cotton after opening from being smoothly conveyed out.
[0074] As a further embodiment of this utility model, a guide plate 9 is installed on the hopper 2. The guide plate 9 is located directly below the roller 802 and is inclined.
[0075] In this embodiment, the spread flat cotton will fall vertically and slide down the guide plate 9 onto the conveyor belt 10 after contacting the guide plate 9. This avoids the conveyor belt 10 pulling the cotton when it comes into contact with the cotton, causing the cotton clump in the hopper 2 to pass quickly between the rollers 802, making the flat cotton too compact and affecting the quality of subsequent processing.
[0076] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
