Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of cotton grabbing machines, and more specifically, to a cotton grabbing machine for the production of sewing thread. Background Technology

[0002] In the production of sewing thread, the cotton grabber is the core equipment for grabbing cotton fiber raw materials and completing the initial opening. Its grabbing uniformity and equipment layout adaptability directly affect the stability of subsequent spinning processes and the utilization rate of workshop space. With the advancement of intensive production in the textile industry, especially the increasing demand for efficient space utilization in small and medium-sized production sites, the structural defects of traditional cotton grabbers have become increasingly prominent: existing cotton grabbers mostly adopt a linear overall layout, with the feeding, grabbing, and discharging mechanisms arranged in a straight line, requiring a long longitudinal or transverse space.

[0003] The drawbacks of traditional linear structures are particularly prominent: in workshops with limited space, linear layouts not only directly occupy a large amount of effective production area, but also require reserved space for operation and maintenance at both ends of the equipment, further reducing the utilization rate of workshop space; in order to adapt to the size of the equipment, the workshop needs to plan an extra long and narrow installation area, which can easily lead to restrictions on the layout of other production equipment and disrupt the compactness of the production process; for scenarios that require flexible adjustment of production capacity or workshop layout, linear cotton grabbers are difficult to move and modify, have poor adaptability, and restrict production expansion and process optimization.

[0004] Therefore, developing a cotton-grabbing machine for sewing thread production that occupies less space and is more adaptable has become an urgent need to solve the pain points of traditional equipment. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a cotton grabbing machine for sewing thread production, which solves the technical problem that existing cotton grabbing machines mostly adopt a linear overall layout, with the feeding, grabbing, and discharging mechanisms arranged in a straight line, requiring a long longitudinal or transverse space.

[0006] According to one aspect, at least one embodiment of this disclosure provides a cotton-grabbing machine for sewing thread production, comprising: The material bin and the inner frame are provided. The material bin has a circular shape with an open top, and the inner frame is fixed to the center of the inside of the material bin. A cotton loading assembly, wherein the cotton loading assembly is disposed in the material bin; A cotton-grabbing assembly is disposed on the material box and the inner frame; The cotton-grabbing assembly includes a housing. The bottom of the housing is rotatably connected to the top of the inner frame via a rotating shaft. A cotton-grabbing opening is provided at the bottom of the housing. A pair of cotton-pressing rollers are rotatably connected to both ends of the cotton-grabbing opening. A pair of cotton-grabbing rollers are rotatably connected to the cotton-grabbing opening and are located between the pair of cotton-pressing rollers.

[0007] As a further technical solution, a rib frame is provided inside the cotton-grabbing opening, the rib frame is located at the lower end of a pair of cotton-pressing rollers, an inner partition is provided inside the outer shell, the inner partition is located above the tail end of the cotton-grabbing roller, and a cotton outlet pipe is provided on the side surface of the inner partition.

[0008] As a further technical solution, one end of the cotton outlet pipe is bent vertically upward and located at the outer end of the top of the material box. Several supports are provided on the top of the material box, and connecting pipes are fixedly connected between the supports. The lower end of the connecting pipe is rotatably connected to the cotton outlet pipe.

[0009] As a further technical solution, a drive motor is provided at the top of the inner frame, a drive gear is provided at the output end of the drive motor, a driven gear is provided at the lower end of the rotating shaft at the bottom of the outer shell, the drive gear meshes with the driven gear, and the cotton pressing roller and the cotton grabbing roller are both driven to rotate by electricity.

[0010] According to another aspect, in at least one embodiment of the present invention, the cotton loading assembly includes an inner bottom plate, which is disposed at the bottom of the material box. A plurality of telescopic hydraulic cylinders are vertically mounted on the outside of the material box. The output end of the telescopic hydraulic cylinders is connected to a connecting frame, which bypasses the top of the material box and connects to the inner bottom plate.

[0011] As a further technical solution, several of the brackets are provided with annular slide rails at their lower ends, and the top of the outer shell is slidably connected to the annular slide rails.

[0012] As a further technical solution, the inner bottom plate has several placement slots on its surface, and the inner bottom plate is connected to the inner frame movable assembly.

[0013] As a further technical solution, the opening area of ​​the cotton-grabbing port can completely cover the placement groove.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: This disclosure solves the problem of large space occupation in traditional linear layouts by using a cotton-grabbing assembly. The circular material box and the central inner frame form a compact structure, with the feeding, gripping, and discharging mechanisms centrally arranged, eliminating the need for a long and narrow installation area, greatly improving the utilization rate of workshop space, and adapting to the needs of small and medium-sized production sites. The outer shell rotates around the inner frame, and with the help of the annular slide rail guide, it can achieve 360° all-round cotton gripping. The cotton gripping opening completely covers the placement groove of the inner bottom plate, avoiding gripping dead corners. The cotton pressing roller and the cotton gripping roller work together to grip the compacted cotton more evenly and reduce fiber waste.

[0015] The cotton outlet pipe is vertically bent and then rotates to fit with the connecting pipe, which does not affect the rotation of the outer shell and ensures smooth output of cotton fibers. The drive gear and driven gear transmission are smooth, ensuring uniform gripping speed. The inner partition and rib frame further optimize the cotton conveying and combing effect. The entire component has a compact structure and high gripping efficiency, saving space and improving the uniformity of cotton gripping, which is suitable for the precision requirements of sewing thread production.

[0024] like Figures 1-3 As shown, it illustrates a cotton-grabbing machine for sewing thread production according to an embodiment of the present disclosure, comprising: The material box 1 and the inner frame 2 are provided. The material box 1 has a circular structure with an open top. The inner frame 2 is fixed at the center of the inside of the material box 1. Cotton loading assembly 4 is disposed in the material box 1; Cotton-grabbing assembly 3 is disposed on the material box 1 and the inner frame 2; The cotton-grabbing assembly 3 includes a housing 3-1. The bottom of the housing 3-1 is rotatably connected to the top of the inner frame 2 via a rotating shaft. A cotton-grabbing opening 3-2 is provided at the bottom of the housing 3-1. A pair of cotton-pressing rollers 3-3 are horizontally rotatably connected to both ends of the cotton-grabbing opening 3-2. A pair of cotton-grabbing rollers 3-4 are rotatably connected inside the cotton-grabbing opening 3-2, and the cotton-grabbing rollers 3-4 are located between the pair of cotton-pressing rollers 3-3. A rib frame 3-5 is provided inside the cotton-grabbing opening 3-2, and the rib frame 3-5 is located at the lower end of the pair of cotton-pressing rollers 3-3. An inner partition 3-6 is provided inside the housing 3-1, and the inner partition 3-6 is located above the tail end of the cotton-grabbing rollers 3-4. The side surface of the inner partition 3-6 is provided with... A cotton outlet pipe 3-7 is provided, with one end of the cotton outlet pipe 3-7 bent vertically upwards and located at the top outer end of the material box 1. Several supports 3-8 are provided on the top of the material box 1, and connecting pipes 3-9 are fixedly connected between the supports 3-8. The lower end of the connecting pipes 3-9 is rotatably connected to the cotton outlet pipe 3-7. A drive motor 3-10 is provided at the top of the inner frame 2, and a drive gear 3-11 is provided at the output end of the drive motor 3-10. A driven gear 3-12 is provided at the lower end of the rotating shaft at the bottom of the outer shell 3-1. The drive gear 3-11 and the driven gear 3-12 mesh with each other. The cotton pressing roller 3-3 and the cotton grabbing roller 3-4 are both driven to rotate by electricity.

[0025] In some examples, in order to achieve precise all-round cotton grabbing of the cotton pile in the material bin 1 and solve the problems of limited cotton grabbing range and uneven cotton grabbing of traditional cotton grabbing machines, a cotton grabbing component 3 was designed. This component includes the material bin 1, which is welded from high-strength steel plate and has a circular top opening structure to provide ample space for cotton pile storage. The inner frame 2 is fixed to the center of the material bin 1 by full welding and adopts a hollow frame structure, which not only ensures the rigidity of the support but also provides installation space for the drive components. The two constitute a stable cotton grabbing base carrier.

[0026] The inner frame 2 has a drive motor 3-10 fixed to its top via a motor mount. The drive gear 3-11 at the output end precisely meshes with the driven gear 3-12 at the lower end of the rotating shaft at the bottom of the outer shell 3-1. The rotating shaft is rotatably connected to the top of the inner frame 2 via a deep groove ball bearing, forming a transmission link that drives the outer shell 3-1 to rotate in a ring around the inner frame 2. The cotton-grabbing opening 3-2 at the bottom of the outer shell 3-1 is integrally cut and formed. The cotton-pressing rollers 3-3 at both ends inside are horizontally rotatably connected via bearings. The roller surface is covered with an anti-slip rubber layer. It is driven by an independent motor to compact and limit the cotton pile. The cotton-grabbing roller 3-4 is located between the two cotton-pressing rollers 3-3. The roller surface is provided with spiral cotton-grabbing teeth. It is heat-treated by quenching to improve wear resistance and works in conjunction with the cotton-pressing rollers 3-3 to achieve uniform gripping.

[0027] The rib frame 3-5 inside the cotton grabbing opening 3-2 is fixed by welding and is distributed in a comb-like pattern at the lower end of the cotton pressing roller 3-3 to comb the cotton pile and prevent clumping. The inner partition 3-6 inside the outer shell 3-1 separates the cotton grabbing area from the cotton guiding area. The cotton outlet pipe 3-7 on the side surface is welded to the inner partition 3-6 and connected. The upper end is vertically bent and connected to the connecting pipe 3-9 between it and the top support 3-8 of the material box 1 through a rotating sealing sleeve to ensure smooth cotton outlet without leakage when the outer shell 3-1 rotates, realizing efficient coordination between annular cotton grabbing and continuous cotton guiding.

[0028] like Figures 1-3 As shown in the figure, the cotton loading assembly 4 in this embodiment includes an inner bottom plate 4-1, which is disposed at the bottom of the material box 1. Several telescopic hydraulic cylinders 4-2 are vertically mounted on the outside of the material box 1. The output end of the telescopic hydraulic cylinders 4-2 is connected to a connecting frame 4-3, which bypasses the top of the material box 1 and is connected to the inner bottom plate 4-1.

[0029] In some examples, in order to achieve smooth rising and efficient replenishment of the cotton pile and solve the problems of frequent machine stops for feeding and uneven cotton grabbing caused by unstable cotton pile height in traditional cotton loading methods, a cotton loading component 4 was designed. This component includes an inner bottom plate 4-1 at the bottom of the material box 1, which is made of steel plate and polished to reduce cotton adhesion. The edges are fixed with sliders by bolts, which slide and cooperate with the vertical grooves preset on the inner wall of the material box 1 to form a guide structure to ensure smooth lifting.

[0030] Several telescopic hydraulic cylinders 4-2 are evenly distributed around the outer circumference of the material box 1. The cylinder body is vertically fixed to the ground by the bracket 3-8. The output end is hinged to the connecting frame 4-3 by the pin. The connecting frame 4-3 is made of angle steel welded together, passes around the top of the material box 1, and the lower end is rigidly connected to the connecting seat on the upper surface of the inner bottom plate 4-1 by bolts. Multiple sets of hydraulic cylinders move synchronously to drive the inner bottom plate 4-1 to rise and fall smoothly.

[0031] The hydraulic cylinder employs a synchronous control system, precisely adjusting the rising speed of the inner bottom plate 4-1 according to the cotton-grabbing progress of the cotton-grabbing component 3, always maintaining the top of the cotton pile at the optimal grabbing height of the grabbing opening 3-2. When the inner bottom plate 4-1 rises to the top of the material box 1, a new cotton pile can be directly added to it without stopping the machine to disassemble parts. After the cotton replenishment is completed, the hydraulic cylinder drives the inner bottom plate 4-1 to slowly descend and reset, achieving a seamless connection between cotton grabbing and replenishment, significantly improving production efficiency, and avoiding cotton grabbing interruption caused by cotton pile collapse.

[0032] For example, such as Figure 2 As shown, several of the brackets 3-8 are provided with annular slide rails 5 at their lower ends, and the top of the outer shell 3-1 is slidably connected to the annular slide rails 5.

[0033] In some examples, the annular slide rail 5 at the lower end of the bracket 3-8 is fixed with bolts. The slide rail is made of wear-resistant stainless steel and has a U-shaped cross-section. A slider adapted to the slide rail is installed on the top of the outer shell 3-1. The slider is embedded in the slide rail to form a sliding fit, which, together with the rotating shaft at the top of the inner frame 2, achieves dual guidance. This structure limits the radial offset of the outer shell 3-1, making the annular rotation smoother, reducing vibration during cotton grabbing, ensuring uniform contact between the cotton grabbing roller 3-4 and the cotton pile, and adapting to the need for long-term continuous cotton grabbing.

[0034] For example, such as Figure 2 As shown, the inner bottom plate 4-1 has several placement slots 6 on its surface, and the inner bottom plate 4-1 is movably connected to the inner frame 2.

[0035] In some examples, the placement grooves 6 on the surface of the inner bottom plate 4-1 are integrally milled into a rectangle with uniform spacing, adapting to the dimensions of the cotton pile. A circular hole is opened in the center of the inner bottom plate 4-1, which fits into the guide column at the bottom of the inner frame 2 to form a central positioning. The placement grooves 6 can divide the cotton pile into sections to avoid mixing, and the central fitting, together with the edge sliding groove, ensures that the inner bottom plate 4-1 is not tilted when it is raised or lowered, improving the stability of the cotton pile rising.

[0036] For example, such as Figure 2 As shown, the opening area of ​​the cotton-grabbing port 3-2 can completely cover the placement groove 6.

[0037] In some examples, the opening area of ​​the cotton-grabbing nozzle 3-2 is precisely calculated to completely cover the area of ​​a single placement slot 6, and the edges of the opening are rounded to avoid snagging the cotton. During cotton grabbing, the outer shell 3-1 rotates in a ring, coordinating with the lifting and lowering of the inner bottom plate 4-1. The cotton-grabbing nozzle 3-2 can grab the cotton piles in each placement slot 6 one by one. The covering design ensures that there are no missed areas. Combined with the synergistic action of the cotton-pressing roller 3-3 and the cotton-grabbing roller 3-4, the cotton in each zone is grabbed evenly.

[0038] In actual use: Place the material box 1 stably at the production station, and fix the inner frame 2 in the center of the material box 1, ensuring that all components are firmly installed; divide the cotton material into the placement slots 6 on the surface of the inner bottom plate 4-1, and connect the inner bottom plate 4-1 to the inner frame 2 in a movable assembly. Drive the connecting frame 4-3 through the telescopic hydraulic cylinder 4-2 on the outside of the material box 1, so that the inner bottom plate 4-1 rises steadily along the inner wall of the material box 1, and the top of the cotton pile reaches the grabbing height of the cotton grabbing component 3; start the drive motor 3-10 on the top of the inner frame 2, and drive the outer shell 3-1 to rotate around the rotation axis on the top of the inner frame 2 through the meshing of the drive gear 3-11 and the driven gear 3-12. The top of the outer shell 3-1 rotates along the annular shape at the lower end of the bracket 3-8. The slide rail 5 slides to ensure smooth rotation; at the same time, the cotton pressing roller 3-3 and the cotton grabbing roller 3-4 are activated. The cotton pressing roller 3-3 compacts the cotton pile to prevent it from becoming loose, while the cotton grabbing roller 3-4 is located between the two to efficiently grab the cotton fibers. The rib frame 3-5 combs the cotton material to prevent clumping. The grabbed cotton fibers are guided into the cotton outlet pipe 3-7 through the inner partition 3-6. The connecting pipe 3-9 between the cotton outlet pipe 3-7 and the top support 3-8 of the material box 1 rotates to ensure smooth cotton output during rotation. During the cotton grabbing process, the telescopic hydraulic cylinder 4-2 continuously drives the inner bottom plate 4-1 to rise slowly, maintaining a stable cotton pile height. After the cotton material is grabbed, new cotton material can be added directly to the inner bottom plate 4-1 without stopping the machine, completing the continuous cotton grabbing process.
