Description

Technical Field

[0001] The utility model relates to the technical field of textile, in particular to a pressure applying device for a yarn guiding leather roller. Background Art

[0002] The leather roller is one of the main parts of the drafting device of a spinning machine. Its center is a steel roller, and the outer layer is wrapped with materials such as leather or artificial rubber. During the textile process, the leather roller and the roller work together to realize the drafting effect on the fibers. This effect is crucial for the production of textiles because it directly affects the quality and performance of the final product.

[0003] Generally speaking, the service life of a fine-spun leather roller is between half a year and one year. If it exceeds one year or there are situations such as surface damage, blistering, and deformation, a new leather roller needs to be replaced. In order to reduce the consumption of leather rollers, a pressure applying device is required to separate the steel roller from the rubber sleeve to realize the secondary utilization of the steel roller. In general pressure applying devices, the rubber sleeves at both ends of the leather roller need to be manually flipped to be separated, and this method requires two pressurizations for a leather roller to be completely disassembled, resulting in low work efficiency. Content of the Utility Model

[0004] The utility model discloses a pressure applying device for a yarn guiding leather roller, aiming to solve the technical problem of low work efficiency in the way that a leather roller needs to be pressurized twice to be completely disassembled.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A pressure applying device for a yarn guiding leather roller includes: a main support seat, a support mechanism arranged on the main support seat, a pressure applying mechanism, a blanking mechanism, and a cleaning mechanism arranged around the support mechanism; the support mechanism includes: a main support table, a plurality of U-shaped brackets fixed equidistantly around the main support table, two U-shaped limit brackets fixed on one side of the U-shaped brackets, a back plate fixed on the top end of the U-shaped limit brackets, a circular through hole arranged on the inner wall of the top end of the main support table, a base fixed on the bottom end of the main support table, and a motor fixedly connected to the bottom end of the base; the pressure applying mechanism includes: a first bracket fixed on the main support seat, a first arc-shaped guiding frame fixed on one side of the first bracket, a hydraulic cylinder fixed on the top end of the main support seat, and a pressure applying rod arranged at the output end of the hydraulic cylinder.

[0007] By setting up a support mechanism and a pressing mechanism, the support mechanism can drive multiple U-shaped limit frames to move intermittently through a motor. Each work station corresponds to a different functional area. In the pressing mechanism, with the guidance of the first arc-shaped guiding frame and the limiting effect of the back plate, the function of automatic correction can be achieved, reducing the requirements for manual operation. In addition, based on the setting of two U-shaped limit frames in each group, the separation of two rubber sleeves can be completed synchronously when the hydraulic cylinder presses down, thus avoiding the cumbersome flipping process and optimizing the work efficiency.

[0008] In a preferred solution, a first through hole, a second through hole, and a third through hole are simultaneously penetrated through the main support seat. The first through hole is correspondingly arranged at the bottom end of the blanking mechanism, the second through hole is correspondingly arranged at the bottom end of the pressing mechanism, and the third through hole is correspondingly arranged at the bottom end of the cleaning mechanism. The blanking mechanism includes: a first support rod fixedly connected to the inner wall of the top end of the main support seat, a circular support plate fixed to the bottom end of the first support rod, and a second arc-shaped guiding frame fixed to the outer wall of one side of the first support rod. The circular support plate is embedded in a circular through hole. The blanking mechanism further includes a through groove penetrated through one side of the U-shaped bracket, a push block movably inserted into the through groove, and an electric telescopic rod installed inside the main support seat. A groove is arranged on one inner wall of the push block, and a plurality of springs are fixedly connected in the groove. The same ends of the plurality of springs are simultaneously connected to one inner wall of the through groove. A second bracket is fixedly connected to the outer wall of the bottom end of the circular support plate, and the electric telescopic rod is installed on the second bracket. A blanking inclined surface is arranged at one end of each group of the lower U-shaped limit frames.

[0009] By setting up a blanking mechanism, the blanking mechanism is used to push the rubber sleeves remaining on the U-shaped limit frames to make them separate. Among them, the upper second arc-shaped guiding frame can push the rubber sleeves to fall as the support mechanism rotates, and the lower rubber sleeves are pushed by the electric telescopic rod during the intermittent movement gap. Thus, the automatic blanking of the rubber sleeves can be realized, and different accessories can be classified and summarized based on the partition separating different spaces.

[0010] In a preferred solution, the cleaning mechanism includes two brushes, a second support rod connected to the brushes, and a torsion spring arranged around the outer circumference of the second support rod. A double-headed motor is arranged between the two brushes, and the two brushes are respectively connected to the two output ends of the double-headed motor. A third bracket is fixedly connected to the outer wall of one side of the double-headed motor, and the third bracket is connected to the second support rod. A cylindrical outer cover is sleeved on the bottom end of the second support rod. The cylindrical outer cover covers the torsion spring, and one end of the torsion spring is fixed to the inner wall of the cylindrical outer cover. A limiting support plate is fixedly connected to the outer wall of the top end of the main support seat. The limiting support plate is located on one side of the second support rod, and under the elastic force of the torsion spring, the third bracket fits against one side of the second support rod. The bottom ends of the two brushes respectively fit against the top ends of each group of two U-shaped limit frames.

[0011] By providing a cleaning mechanism, two brushes, upper and lower, are rotated by a double-headed motor in the cleaning mechanism. When the support mechanism moves from the blanking mechanism to the cleaning mechanism, the corresponding two U-shaped brackets come into contact with the double-headed motor during rotation, and as the continuous rotation drives the brushes to squeeze into the U-shaped brackets, the surface thereof is cleaned. Thus, the residue on the surface of the U-shaped brackets after the aged rubber sleeve is pressurized can be cleaned, thereby ensuring the overall service life of the support mechanism and the pressing accuracy of the pressing mechanism.

[0012] As can be seen from the above, a pressing device for a yarn guiding roller comprises: a main support base, a support mechanism arranged on the main support base, a pressing mechanism arranged around the support mechanism, a blanking mechanism and a cleaning mechanism; the support mechanism comprises: a main support platform, a plurality of U-shaped brackets equidistantly fixed around the main support platform, two U-shaped limit frames fixed on one side of the U-shaped brackets, a back plate fixed at the top end of the U-shaped limit frames, a circular through hole arranged on the inner wall of the top end of the main support platform, a base fixed at the bottom end of the main support platform, and a motor fixedly connected to the bottom end of the base; the pressing mechanism comprises: a first support fixed on the main support base, a first arc-shaped guiding frame fixed on one side of the first support, a hydraulic cylinder fixed on the top end of the main support base, and a pressing rod arranged at the output end of the hydraulic cylinder. The pressing device for the yarn guiding roller provided by the present utility model has the technical effects that the self-correction of the position of the roller can be realized, the requirement for manual operation is reduced, and the optimization of the working efficiency is synchronously realized.

In the pressure mechanism 3, when the leather roller is manually placed, as the support mechanism 2 drives the multiple groups of U-shaped limit frames 207 to rotate and move towards the pressure mechanism 3, the surface of the leather roller contacts the first arc-shaped guiding frame 303. With the guidance of the first arc-shaped guiding frame 303 and the limiting effect of the back plate 206, the position of the leather roller can be just right when it reaches the bottom of the hydraulic cylinder 301, thereby realizing the function of automatic correction and reducing the requirements for manual operation. In addition, based on the setting of two U-shaped limit frames 207 in each group, the detachment of two rubber sleeves can be completed synchronously when the hydraulic cylinder 301 presses down, thus avoiding the cumbersome flipping process and optimizing the work efficiency.

[0026] Reference Figure 3 and Figure 4 In a preferred embodiment, the outer wall of the bottom end of the circular support plate 403 is fixedly connected with a second bracket 405, and the electric telescopic rod 404 is installed on the second bracket 405, and one end of each group of U-shaped limit frames 207 located below is provided with a material discharge slope 410, and the material discharge mechanism 4 is used to push the rubber sleeve left on the U-shaped limit frame 207 to make it detach, wherein the second arc guide frame 402 of the upper part contacts with the upper rubber sleeve as the support mechanism 2 rotates, and can push it to fall, and the rubber sleeve below is in the gap of intermittent movement, and the electric telescopic rod 404 pushes the push block 406 to extend it a short distance, pushing the rubber sleeve to the position of the unloading slope 410, thereby realizing the unloading of the rubber sleeve below, and then under the rebound action of the spring 408, the push block 406 is driven to return to its position, thereby realizing automatic unloading of the rubber sleeve, and based on the partition 9, different spaces are separated to realize the classification and induction of different accessories. At the same time, the setting of the unloading slope 410 does not affect the pressurizing operation of the pressurizing mechanism 3. Based on the clamping of the first arc guide frame 303 and the back plate 206, the rubber sleeve can be guaranteed to be separated from the steel roller during the pressurizing process.

[0027] Reference Figure 5 In a preferred embodiment, the cleaning mechanism 5 includes two brushes 501 , a second support rod 504 connected to the brushes 501 , and a torsion spring 505 arranged around the outer circumference of the second support rod 504 .

[0028] Reference Figure 5 In a preferred embodiment, a double-headed motor 502 is arranged between the two brushes 501, and the two brushes 501 are respectively connected to the two output ends of the double-headed motor 502, a third bracket 503 is fixedly connected to the outer wall of one side of the double-headed motor 502, and the third bracket 503 is connected to the second support rod 504.

[0029] Reference Figure 5 In a preferred embodiment, the bottom end of the second support rod 504 is sleeved with a cylindrical outer cover 506, the cylindrical outer cover 506 covers the outside of the torsion spring 505, and one end of the torsion spring 505 is fixed to the inner wall of the cylindrical outer cover 506, and the top outer wall of the main support seat 1 is fixedly connected to the limiting support plate 507.

[0030] Reference Figure 5, in a preferred embodiment, the limiting support plate 507 is located on one side of the second support rod 504. Under the elastic force of the torsion spring 505, the third support 503 fits against one side of the second support rod 504. The bottom ends of the two brushes 501 respectively fit against the tops of each group of two U-shaped limiting frames 207. In the cleaning mechanism 5, the upper and lower brushes 501 are driven to rotate by the double-headed motor 502. In the initial state, under the elastic force of the torsion spring 505, the second support rod 504 is driven to rotate towards the position of the limiting support plate 507, causing the third support 503 to fit against one side of the limiting support plate 507. Thus, when the support mechanism 2 moves from the blanking mechanism 4 to the cleaning mechanism 5, the corresponding two U-shaped brackets 205 contact the double-headed motor 502 during rotation. With continuous rotation, the brushes 501 are driven to squeeze into the U-shaped brackets 205, and the torsion spring 505 is stretched. When reaching the cleaning station, the brushes 501 just fit against the tops of the U-shaped brackets 205 and rotate to clean their surfaces. With continuous movement, the brushes 501 can be separated from the U-shaped brackets 205 and return to their original positions under the rebounding action of the torsion spring 505. Thus, the residue of the aged rubber sleeve on the surface of the U-shaped bracket 205 after pressing can be cleaned, thereby ensuring the overall service life of the support mechanism 2 and the pressing accuracy of the pressing mechanism 3.

[0031] Working principle: The support mechanism 2 can drive multiple U-shaped limiting frames 207 to move intermittently through the motor 201. Each station corresponds to a different functional area. In the pressing mechanism 3, when the rubber roller is manually placed, as the support mechanism 2 drives multiple groups of U-shaped limiting frames 207 to rotate and move towards the pressing mechanism 3, the surface of the rubber roller contacts the first arc-shaped guiding frame 303. With the guidance of the first arc-shaped guiding frame 303 and the limiting effect of the back plate 206, the position of the rubber roller can be just right when it reaches the bottom of the hydraulic cylinder 301, thus achieving the function of automatic correction and reducing the requirements for manual operation. In addition, based on the setting of each group of two U-shaped limiting frames 207, the separation of the two rubber sleeves can be completed synchronously when the hydraulic cylinder 301 presses down, thus avoiding the cumbersome flipping process and optimizing the work efficiency.
