Description

Technical Field

[0001] This utility model relates to a sliver can turntable, which drives the sliver can to rotate during the process of the coiler putting the cotton sliver into the sliver can in a designed manner. The sliver can turntable can be used in carding machines, drawing machines or combing machines. Background Technology

[0002] In a spinning mill, after initial treatments such as breaking down, mixing, and cleaning in the opening and cleaning workshop, the fiber material is supplied to the carding machine via a pipeline conveying system. The fiber material is cleaned and parallelized in the carding machine to produce slivers. The resulting slivers are collected into cans according to process requirements and then transported downstream to the drawing frame for further processing. Multiple slivers are combined, drafted, and made into uniform fiber slivers, which are then placed into cans according to the design. In a downstream process, multiple slivers are processed into laps by a winding machine and then combed by a combing machine to further remove short fibers and impurities and parallelize the fibers, finally forming slivers that are placed into cans as required. In all these machines, during the process of placing the slivers into the cans as required, the coiler itself rotates to guide the slivers, and the cans below the coiler also need to rotate under the drive of a turntable to ensure that the slivers are stored in the cans according to the design requirements.

[0003] A sliver can turntable typically has a disc for supporting the sliver can. The disc's surface has grooves to hold the sliver in place, preventing slippage during rotation. The disc is fixed to a drive unit below it with screws. The drive unit has a bearing; the inner ring of the bearing is fixed to the machine base, and the outer ring is a rotatable disc fixedly connected to the disc. This disc is driven by a motor via a belt. During operation, the motor drives the belt, which in turn drives the outer ring of the bearing, causing the disc to rotate. As sliver is filled, the weight of the sliver can increases. During rotation, the disc supporting the sliver can sometimes tilt, resulting in poor sliver winding and potentially damaging the turntable and bearing. During the removal of a full sliver can, its weight also easily causes the disc to tilt. Therefore, multiple support rollers are evenly spaced around the circumference of the disc on the machine base below to prevent tilting, but their effectiveness is limited, and the overall bearing structure is complex and costly.

[0004] To address the load-bearing issues of bar-type turntables, various rolling bearing structures are known in the mechanical field. Among them, the four-point contact ball bearing alters the cross-sectional profile of the annular raceways of the inner and outer rings, optimizing the force and contact states between the balls and the inner and outer rings. This allows it to simultaneously withstand axial and radial loads, preventing tilting, improving stability, and extending bearing life. Chinese patent application CN101769302A discloses a four-point contact ball bearing with a gear ring, where the outer ring has a gear on its outer side. It can directly form a gear transmission pair with other gears or racks. However, this gear drive structure is complex, requires high machining precision, and is costly. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a sliver can turntable and a carding machine, drawing machine or combing machine having the sliver can turntable. The bearing of the sliver can turntable can bear axial load and radial load at the same time, making it more stable during rotation. The sliver can will not tilt. The support wheel under the disc can also be omitted. The overall structure is simple, easy to install and maintain, and low in cost.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a strip drum turntable, comprising:

[0007] The base has a receiving cavity;

[0008] A bearing, wherein the bearing is disposed in a receiving cavity, includes an inner ring, an outer ring, and rollers disposed between the inner ring and the outer ring, wherein the inner ring is fixed on a base;

[0009] A disc, which is disposed above the bearing and fixedly connected to the outer ring of the bearing, is used to hold the strip tube;

[0010] The bearing has a first groove on the outer side of its outer ring to accommodate a belt, which is wound around the outer ring of the bearing and connected to the motor.

[0011] Furthermore, the bearing diameter is 0.4 to 0.7 times the diameter of the disk, and the diameter of the disk is smaller than the diameter of the strip.

[0012] Furthermore, a sealing ring is provided in the gap between the inner ring and the outer ring.

[0013] Furthermore, an adjustable bracket is installed on the base, and a tensioning wheel is installed on the bracket. A second groove for accommodating the belt is provided on the outer side of the tensioning wheel.

[0014] Optionally, the base may be provided with multiple receiving cavities, and the inner wall between adjacent receiving cavities is provided with a belt channel that runs through the two receiving cavities. The belt passes through the belt channel and is respectively wrapped around the first groove of the bearing outer ring in the receiving cavity.

[0015] Furthermore, the surface of the disc is provided with multiple roller grooves to accommodate the bottom of the strip tube.

[0016] Furthermore, the bearing is a four-point contact ball bearing.

[0017] This utility model also relates to a carding machine, which includes the aforementioned sliver can turntable.

[0018] This utility model also relates to a drawing frame, which includes the aforementioned carding can turntable.

[0019] This utility model also relates to a combing machine, which includes the aforementioned sliver can turntable.

[0020] The beneficial effects of this utility model are:

[0021] (1) The four-point contact ball bearing used in this utility model is a structure that can bear both radial and axial loads at the same time. It is also set with a suitable size ratio, which combines stability and economy. Compared with the existing ordinary rolling bearings, it can keep the turntable running stably when the weight of the sliver increases, thereby ensuring that the cotton sliver can be stored in the sliver as required and reducing the damage to the turntable and bearing caused by the tilt of the sliver. Moreover, it has a simple structure and low cost.

[0022] (2) By directly fixing the disc to the outer ring of the bearing, this utility model eliminates the need for multiple support wheels used to prevent tilting in the traditional structure, making the overall structure simpler, reducing the number of parts, and facilitating assembly and maintenance.

[0029] The present invention will now be further described with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] like Figures 1 to 3 The diagram shows a sliver can turntable, such as the sliver can turntable structure of a drawing frame (or a carding machine or combing machine). Figure 1 and Figure 3 The left side of the diagram shows a temporary storage location for empty sliver cans, which includes some known sliver can drive mechanisms. The right side shows the specific structure of the sliver can turntable, which is the working position of the sliver can. The sliver can turntable shown includes a base 1, a bearing 2, and a disc 3. The base 1 has a receiving cavity 11; the bearing 2 is a four-point contact ball bearing, which includes an inner ring 21, an outer ring 22, and rollers 23 disposed between the inner ring 21 and the outer ring 22. A sealing ring 6 is provided in the gap between the inner ring 21 and the outer ring 22 to prevent impurities such as cotton dust and fiber debris from entering the bearing and to inhibit grease leakage, thereby maintaining the lubrication and cleanliness of the rolling elements and raceways. The inner ring 21 is fixed to the base 1 by fasteners. Figure 3 As shown, the disc 3 is positioned above the bearing 2 and fixedly connected to the outer ring 22 of the bearing 2. The disc 3 is used to support the slab tube, and its upper surface has multiple roller grooves 31 spaced along the circumferential direction. The roller grooves 31 are used to accommodate and position the rollers or roller flanges at the bottom of the slab tube, thereby limiting the radial and circumferential positions of the bottom of the slab tube relative to the disc 3. This ensures that the bottom of the slab tube is guided and reliably supported when the disc 3 rotates with the outer ring 22. Figure 1 The disk 3 is not shown in the diagram, so specific structures such as the bearing 2 are visible. Figure 3 Disk 3 is shown in the image.

[0031] like Figure 1 and 2 As shown, the outer ring 22 of the bearing 2 has a first groove 221 for accommodating the belt 4. The belt 4 is wound around the outer ring 22 of the bearing 2 and connected to the motor 5. In this embodiment, the diameter of the bearing 2 is set between 0.4 and 0.7 times the diameter of the disc 3. Different diameter discs (and / or bearings) are used for different diameter slats. For example, for a slat with a diameter of 1000 mm, the bearing diameter can be 608 mm and the disc diameter can be 970 mm. For a slat with a diameter of 1200 mm, the bearing diameter can be 608 mm and the disc diameter can be 1160 mm. Since the slat relies on the roller at its bottom to be embedded in the groove on the disc, and the roller is located within the area where the bottom of the slat is located, the diameter of the disc 3 can be slightly smaller than the diameter of the slat, which helps to reduce costs.

[0032] like Figure 1 and Figure 2As shown, a bracket 7 is mounted on the base 1 via fasteners. A tensioning wheel 8 is rotatably mounted on the bracket 7 via a pin. The outer circumference of the tensioning wheel 8 forms an annular second groove 81 that matches the cross-section of the belt 4. The tensioning wheel 8 is used to adjust the tension of the belt 4 to prevent the belt from being too tight or too loose. The belt is wound around the first groove 221 of the bearing outer ring 22 and the output end of the motor to form a closed transmission circuit. At the tensioning wheel 8, the belt 4 contacts the outer arc surface of the tensioning wheel 8 in a tangential manner. The tensioning wheel 8 is located on the outside of the belt 4 circuit.

[0033] In another embodiment of this patent, such as a double-eye drawing machine, as... Figure 1 Combination Figure 4 As shown, a receiving cavity 11 is provided on the base 1 corresponding to the two eyes of the drawing frame. Each receiving cavity 11 is provided with an independent bearing 2 and a disc 3 fixedly connected to the outer ring 22 of the bearing. A sliver can turntable is provided above the disc 3 for holding the sliver cans. A belt channel is provided on the inner wall between the two receiving cavities 11, which runs through the two receiving cavities 11. The belt 4 passes through the belt channel and is wound around the first groove 221 of the outer ring 22 of the bearing 2 in the receiving cavity 11.

[0034] The belt passes through the first groove 221 of the outer rings 22 of the two bearings and is wound around the output end of the motor to form a closed transmission circuit, so that one motor 5 drives the same belt and thus synchronously drives the two discs 3 and the strip drum above them to rotate. In order to limit the direction of the belt 4 and adjust the tension of the belt 4, an adjustable tensioning wheel 8 can be set on the base 1 at an adjacent position of any receiving cavity 11 as needed, for example... Figure 4 The belt 4 is provided with two tensioning pulleys 8. The belt 4 is in tangential contact with the outer arc surface of the two tensioning pulleys 8. The two tensioning pulleys 8 are located on the outside of the belt 4 circuit. By adjusting the position of the tensioning pulleys 8, the belt 4 is tensioned according to the design requirements and a stable transmission path is maintained between the motor output end and the two bearings 2.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
