Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically to a cotton yarn sliver cutting device for cotton yarn processing. Background Technology

[0002] Cotton yarn is yarn made from cotton fibers through a spinning process. After removing impurities, the cotton fibers are processed using a crimping machine to turn the clumps of cotton fibers into cotton yarn strips. The cotton yarn strips are then collected and cut after a certain length to facilitate subsequent plying.

[0003] For example, the cotton sliver cutting device disclosed in patent CN219768367U, while convenient for installation and removal, uses a linkage mechanism to move multiple jaws away from the take-up drum, allowing the take-up drum to be removed from the support shaft. After placing a new take-up drum on the support shaft, the jaws can be controlled again by the linkage mechanism to fix the take-up drum. However, in actual use, when the cutting blade wears down, it needs to be replaced. The cutting blade is generally installed on the cutting tool using bolts or other fasteners, which requires unscrewing the bolts or other fasteners during the replacement process, making the operation cumbersome. Therefore, improvements are needed. Utility Model Content

[0031] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0032] The following is in conjunction with the appendix Figures 1-8This embodiment will be described in further detail.

[0033] Combination Figures 1-8 As shown, a cotton yarn sliver cutting device for cotton yarn processing in this embodiment includes a processing table 100, on which a cutting assembly is provided; the cutting assembly includes a cutting seat 110, with first cylinders 109 on both sides of the cutting seat 110, and a mounting block 111 between the output ends of the two first cylinders 109, with a detachable cutting blade 112 on the mounting block 111 via a mounting assembly; the mounting block 111 is also provided with a fixing assembly for fixing the cotton yarn sliver; a guiding assembly for guiding the cotton yarn sliver is provided on one side of the cutting seat 110; and a winding assembly for winding the cotton yarn sliver is provided on the other side of the cutting seat 110.

[0034] In this embodiment, a fixed frame 101 is provided on the processing table 100 located on one side of the guide assembly. The fixed frame 101 has a groove with an upper port, and a yarn feeding roller 102 is placed between the two grooves.

[0035] In actual use, the yarn feeding roller 102 is placed in the groove, and the cotton yarn strip to be cut on the yarn feeding roller 102 is guided by the guide assembly so that it can pass through the cutting assembly and be wound around the winding assembly. After the cotton yarn strip is wound to a certain length by the winding assembly, the cotton yarn strip located on the cutting seat 110 is fixed by the fixing assembly, and the two first cylinders 109 drive the mounting block 111 to drive the cutting blade 112 to move down to cut the cotton yarn strip, so that a certain length of cotton yarn strip can be collected for subsequent plying processing.

[0036] Specifically, a protrusion 400 is provided on the upper side of the cutting seat 110 along its length direction, and a cutting groove 401 is provided on the protrusion 400 along its length direction. The cutting groove 401 is located directly below the cutting blade 112, so that the cotton yarn is cut in the cutting groove 401, and the lint generated when cutting the cotton yarn strip can be collected in the cutting groove 401, thereby facilitating the discharge of the lint.

[0037] In actual use, when the cutting blade 112 wears out, the installation component allows the cutting blade 112 to be disassembled and installed on the mounting block 111 for replacement. Compared with the existing ones, the process of disassembling and installing the cutting blade 112 through the installation component in this embodiment is simpler.

[0038] The fixing component secures the cotton yarn strip on the cutting seat 110, preventing it from moving during cutting and ensuring optimal cutting. After cutting, one side of the cotton yarn strip is wound up by the winding component, while the other side remains fixed, preventing it from slipping off the cutting seat 110 onto the processing table 100, thus facilitating the next cutting.

[0039] The guide component guides the cotton yarn so that it can pass through the cutting component more effectively. At the same time, the guide component can also tension the cotton yarn so that it does not move on the cutting seat 110, thereby allowing the cotton yarn to be cut more effectively.

[0040] Combination Figures 5-7 As shown, in this embodiment, the lower side of the mounting block 111 is provided with a mounting groove for inserting the cutting blade 112, and the cutting blade 112 is provided with a mounting hole 700. The mounting block 111 is provided with a cavity 500 communicating with the mounting groove. The mounting assembly includes a locking rod 501 that is slidable in the corresponding cavity 500. The locking rod 501 located in the cavity 500 is provided with an abutment piece 604. The locking rod 501 located in the cavity 500 is also sleeved with a first spring 600. The first spring 600 is used to push the abutment piece 604 to drive the locking rod 501 to insert into the corresponding mounting hole 700 to install the cutting blade 112. The lower side of the mounting block 111 is also provided with a scraping member for scraping the surface of the cutting blade 112.

[0041] In this embodiment, the upper side wall of the cutting blade 112 is provided with a first inclined surface 701, and one end of the locking rod 501 is provided with a second inclined surface 603 that is adapted to the first inclined surface 701; the other end of the locking rod 501 extends out of the cavity 500, and the two extended ends of the locking rod 501 are connected by a connecting plate 601, and a handle 602 is provided on the connecting plate 601.

[0042] In practical use, the cutting blade 112 is moved upwards and inserted into the mounting groove, so that the first inclined surface 701 can fit against the second inclined surface 603. Then, the cutting blade 112 is moved upwards further, allowing the first inclined surface 701 to slide and press against the second inclined surface 603. This allows the second inclined surface 603 to drive the locking rod 501, which in turn drives the abutment piece 604 to compress the first spring 600 and retract it into the cavity 500. When the mounting hole 700 is aligned with the cavity 500, the first spring 600, under its action, pushes the abutment piece 604 to insert the locking rod 501 into the mounting hole 700, thus controlling the cutting blade 112. The first cylinder 109 fixes the cutting blade 112 so that it can be installed. When the cutting blade 112 needs to be disassembled, the first cylinder 109 drives the mounting block 111 to move the cutting blade 112 downward so that the lower end of the cutting blade 112 can abut against the bottom wall of the cutting groove 401. At this time, by pulling the handle 602 outward, the handle 602 can drive the connecting plate 601 to move the two locking rods 501 out of the mounting hole 700 and retract into the cavity 500. At this time, the first cylinder 109 drives the mounting block 111 to move upward so that the cutting blade 112 can be disassembled from the mounting groove, thereby completing the disassembly of the cutting blade 112.

[0043] In actual use, the cutting blade 112 is adapted to the mounting groove, allowing the side wall of the cutting blade 112 to slide against the corresponding side wall of the mounting groove. This prevents the cutting blade 112 from shaking within the mounting groove and ensures optimal installation, resulting in better cutting of the cotton yarn strip. Furthermore, both the locking rod 501 and the mounting hole 700 are square and adapted to each other, allowing the side wall of the locking rod 501 to slide against the corresponding side wall of the mounting hole 700. This prevents the cutting blade 112 from shaking vertically within the mounting groove, thus ensuring optimal fixation of the cutting blade 112.

[0044] In order to ensure that the first inclined surface 701 is always aligned with the second inclined surface 603, in this embodiment, both the cavity 500 and the abutment piece 604 are square and are compatible with each other, so that the side wall of the abutment piece 604 can slide and fit against the corresponding side wall of the cavity 500, thereby preventing the locking rod 501 from shaking inside the cavity 500, thus ensuring that the first inclined surface 701 is always aligned with the second inclined surface 603.

[0045] In this process, when the cutting blade 112 cuts the cotton yarn strip, some lint will adhere to the surface of the cutting blade. In order to prevent the lint on the cutting blade 112 from adhering to the cotton yarn strip and affecting subsequent processing, a scraping component is set up so that the scraping component can scrape the lint on the surface of the cutting blade 112, thereby better preventing the lint on the cutting blade 112 from adhering to the cotton yarn strip.

[0046] Combination Figure 8As shown, in this embodiment, the scraping component includes long strips 800 disposed on both sides of the cutting blade 112. The long strips 800 are disposed along the length direction of the cutting blade 112. The long strips 800 are provided with T-shaped grooves 801. The grooves 801 are provided with slidable scrapers 502 for scraping the surface of the cutting blade 112.

[0047] In this embodiment, one end of the chute 801 is open, and a block is provided at the opening position, so that the scraper 502 can be slidably installed in the chute 801. The side wall of the scraper 502 slides against the side wall of the cutting blade 112. The scraper 502 slides along the chute 801, so that the scraper 502 can slide and scrape the shavings on the surface of the cutting blade 112, thereby cleaning the surface of the cutting blade 112.

[0048] In actual use, to prevent the scraper from interfering with the cutting blade 112 in cutting the cotton yarn, in this embodiment, a positioning bolt 802 is provided at a position of the long block 800 away from the side wall of the cutting blade 112. The scraper 502 is slid to one end of the groove 801. At this time, the positioning bolt 802 is turned so that one end of the positioning bolt 802 can abut against the side wall of the groove 801, thereby blocking the scraper 502. This can better prevent the scraper 502 from sliding into the groove 801 located on both sides of the cutting blade 112 and interfering with the cutting blade 112 in cutting the cotton yarn.

[0049] Combination Figures 2-4 As shown, in this embodiment, a placement groove is formed by the indentation on one side of the upper side of the cutting seat 110, and a rotatable first rotating roller 204 is provided in the placement groove; the fixing assembly includes a mounting plate 200 provided on one side wall of the mounting block 111, a sliding column 206 is provided on the mounting plate 200, a U-shaped mounting bracket 203 is provided at the lower end of the sliding column 206, a rotatable second rotating roller 205 is provided between the opposite side walls of the mounting bracket 203, and an abutment block 201 is provided at the upper end of the sliding column 206.

[0050] In practical use, a second spring 202 is fitted onto the sliding column 206 located between the mounting plate 200 and the mounting bracket 203. The first cylinder 109 drives the mounting block 111 to move the mounting plate 200 downwards, allowing the mounting plate 200 to drive the sliding column 206 to move the mounting bracket 203 downwards. This allows the mounting bracket 203 to move the second rotating roller 205 downwards to abut against the first rotating roller 204, fixing the cotton yarn. At this time, the first cylinder 109 continues to drive the mounting block 111 to move the mounting plate 200 downwards, allowing the mounting plate 200 to move downwards along the sliding column 206 and... The second spring 202 is compressed, which pushes the mounting bracket 203 to drive the second rotating roller 205 to press against the cotton yarn strip. After the cutting blade 112 cuts the cotton yarn strip, the first cylinder 109 drives the mounting block 111 to move the mounting plate 200 upward. When the mounting plate 200 moves upward and abuts against the lower side wall of the abutment block 201, the first cylinder 109 stops driving the mounting plate 200 upward. At this time, the second rotating roller 205 still abuts against the first rotating roller 204 to fix the cotton yarn strip, thereby better preventing the cotton yarn strip from slipping off the cutting seat 110 onto the processing table 100.

[0051] In actual use, when the first cylinder 109 continues to drive the mounting plate 200 to move upward, the mounting plate 200 can drive the abutment block 201 to drive the sliding column 206 to move upward, which in turn can drive the mounting frame 203 to drive the first rotating roller 204 to move upward, thereby releasing the fixation of the cotton yarn strip.

[0052] When the first rotating roller 204 abuts against the second rotating roller 205, the rotatable arrangement of the first rotating roller 204 and the second rotating roller 205 makes it easy for the operator to pull the cut cotton yarn strip and wrap it around the winding assembly so that the next section of cotton yarn strip can be cut.

[0053] The first rotating roller 204 is rotatably mounted in the placement groove via a bearing, so that the first rotating roller 204 can be rotatably mounted in the placement groove; the second rotating roller 205 is rotatably mounted on the opposite side wall of the mounting frame 203 via a bearing, so that it can be rotatably mounted on the mounting frame 203.

[0054] Specifically, the opening on one side of the placement groove facilitates the installation of the first rotating roller 204.

[0055] Combination Figure 1As shown, in this embodiment, the guide assembly includes fixed plates 103 disposed opposite to each other on both sides of the cutting seat 110. A rotatable first guide roller 108 is provided between the opposing fixed plates 103. A lifting groove is provided on the fixed plate 103 located above the first guide roller 108. A lifting plate 104 is provided in the lifting groove. A rotatable second guide roller 106 is provided between the two lifting plates 104. A rotatable threaded rod 105 is provided on the lifting plate 104. The threaded rod 105 is threaded through the upper side wall of the lifting groove and extends out.

[0056] In actual use, the lower end of the threaded rod 105 is rotatably mounted on the upper side wall of the lifting plate 104 via a bearing, so that the two threaded rods 105 rotate synchronously, and the threaded rods 105 can drive the corresponding lifting plate 104 to drive the second guide roller 106 to rise and fall, thereby adjusting the distance between the first guide roller 108 and the second guide roller 106, so that both thick and thin cotton yarn strips can be guided and tensioned.

[0057] In actual use, the lifting plate 104 is adapted to the lifting groove, so that the side wall of the lifting plate 104 can slide and fit against the corresponding side wall of the lifting groove, so that the lifting groove can limit the lifting plate 104, thereby allowing the lifting plate 104 to be lifted better.

[0058] Specifically, both ends of the first guide roller 108 are rotatably mounted on the corresponding fixed plate 103 via bearings, and both ends of the second guide roller 106 are rotatably mounted on the corresponding lifting plate 104 via bearings, so that both the first guide roller 108 and the second guide roller 106 can be rotatably mounted.

[0059] Combination Figure 1 As shown, in this embodiment, the winding assembly includes a vertical plate 116, a rotatable rotating shaft 114 on the vertical plate 116, a winding drum 115 sleeved on the rotating shaft 114, a slot along the axial direction of the rotating shaft 114, and a locking block that can extend into the slot inside the winding drum 115.

[0060] In actual use, a motor 117 is provided on one side of the vertical plate 116, and one end of the rotating shaft 114 is connected to the output end of the motor 117. One end of the cotton yarn is wound around the take-up drum 115. Through the setting of the slot and the block, the motor 117 can drive the rotating shaft 114 to drive the take-up drum 115 to rotate, thereby winding up the cotton yarn.

[0061] In actual use, the processing table 100 is equipped with a second cylinder 113, and the output end of the second cylinder 113 is equipped with an arc-shaped block. The other end of the rotating shaft 114 is attached to the arc-shaped block, so that the corresponding end of the take-up drum 115 can abut against the side wall of the arc-shaped block, so that the take-up drum 115 can be limited.

[0062] The slot has an opening at one end. When the take-up drum 115 needs to be removed from the rotating shaft 114, the arc-shaped block is driven to move down by the second cylinder 113, thereby exposing the other end of the rotating shaft 114, so that the take-up drum 115 can be taken out from the slot opening.

[0063] In practical use, the unwinding roller 102 is placed on the fixed frame 101, and the cotton yarn strip to be cut on the unwinding roller 102 is passed between the first guide roller 108 and the second guide roller 106 for tensioning and guidance. It then passes through the cutting seat 110 and is wound onto the take-up drum 115. The rotating shaft 114, driven by the motor 117, rotates the take-up drum 115 to wind the cotton yarn strip. When a certain length is reached, the mounting block 111, driven by the first cylinder 109, moves the mounting plate 200 and the cutting blade 112 downwards, allowing the second rotating roller 205 and the first rotating roller 204 to engage the cutting seat 110. The cotton yarn strip on the cutting seat 110 is fixed. At this time, the first cylinder 109 continues to drive the mounting block 111 to move the cutting blade 112 down to cut the cotton yarn strip. After the cotton yarn strip is cut, the first cylinder 109 drives the mounting block 111 to move the mounting plate 200 up. When the mounting plate 200 abuts against the lower side of the abutment block 201, the first cylinder 109 stops moving up. At this time, the second rotating roller 205 and the first rotating roller 204 can always fix the cotton yarn strip on the cutting seat 110 so that the operator can pull the cut cotton yarn strip and make it wrap around the winding assembly for cutting the next section of cotton yarn strip.

[0064] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
