Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically to a cutting mechanism for a textile shearing machine. Background Technology

[0002] The shearing machine is one of the main pieces of equipment in textile finishing processes. It includes components such as the feed roller, front guide roller, brushing roller, shearing roller, rear guide roller, and output roller. After processing, the fabric surface develops pile of varying lengths. The shearing machine's function is to cut these piles to a fixed length to improve the product's quality and grade.

[0003] A search revealed a Chinese patent (CN206245068U) disclosing a shearing machine, comprising a frame, transmission rollers, and a shearing device. The transmission rollers include a front guide roller and a rear guide roller, both ends of which are mounted on the frame via bearing seats. The frame is equipped with a tension adjustment mechanism, which includes a through groove on the frame for the bearing seats to move and a threaded pusher. One end of the threaded pusher is rotatably connected to the frame, and the other end is threadedly connected to the bearing seat. The frame is also equipped with a reminder device for detecting the surface tension of the fabric and issuing a prompt. This shearing machine, by incorporating a tension adjustment mechanism and a reminder device, enables timely prompting when the reminder device detects that the fabric tension is insufficient, allowing the operator to adjust the fabric tension promptly using the tension adjustment mechanism.

[0004] The aforementioned patent uses a threaded pusher to move the guide roller, thereby adjusting the fabric tension. However, in actual use, the shearing machine will generate a certain degree of vibration. Long-term vibration may cause the threaded pusher to rotate autonomously, thereby causing the guide roller to move and resulting in excessive or insufficient tension on the fabric. Therefore, we propose a cutting mechanism for a textile shearing machine. Summary of the Invention

[0005] The technical problem to be solved by this application is: the tension of the fabric is adjusted by pushing the guide roller to move through the threaded pusher. However, in actual use, the shearing machine will generate a certain degree of vibration when it is working. The long-term vibration may cause the threaded pusher to rotate on its own, thereby causing the guide roller to move and making the tension of the guide roller on the fabric too large or too small.

[0006] To solve the above-mentioned technical problems, this application provides a cutting mechanism for a textile shearing machine, including a U-shaped frame. A front guide roller and a rear guide roller are arranged between the opposite outer surfaces of the left and right sides of the U-shaped frame. The front guide roller and the rear guide roller are respectively located on the front and rear sides of the cutting assembly. A tension adjusting assembly and a limiting assembly are installed on one side of the U-shaped frame. The tension of the front guide roller on the fabric is adjusted by adjusting the position of the front guide roller through the tension adjusting assembly. The limiting assembly is used to limit the tension adjusting assembly to prevent the tension adjusting assembly from easily operating under external force.

[0007] In some embodiments, the tension adjustment assembly includes a fixed frame mounted on one side of a U-shaped frame, a threaded rod rotatably connected inside the fixed frame, a threaded block threadedly connected to the outer surface of the threaded rod, a front guide roller disposed on one side of the threaded block, one end of the threaded rod rotatably penetrating the outer surface of the fixed frame, and a turntable disposed on the side of the threaded rod located outside the fixed frame.

[0008] In some embodiments, the limiting assembly includes a fixed plate, which is sleeved on the outer surface of the threaded rod located outside the fixed frame. Two limiting rods are movably inserted into the outer surface of the fixed plate. The outer surface of the fixed frame has a plurality of limiting holes arranged in a circumferential array. One end of each of the two limiting rods is movably inserted into two of the limiting holes. The other end of each of the two limiting rods is connected to a connecting plate, which is movably sleeved outside the threaded rod. Two springs are connected between the connecting plate and the fixed plate, and the two springs are respectively sleeved outside the two limiting rods. A pull rod is connected to the outer surface of the connecting plate, and one end of the pull rod movably penetrates the outer surface of the turntable.

[0009] In some embodiments, an electrostatic adsorption component is provided between the opposite outer surfaces of the left and right sides of the U-shaped frame. The electrostatic adsorption component is positioned above the front guide roller and is used to adsorb the lint on the fabric and make it stand up.

[0010] In some embodiments, the electrostatic adsorption assembly includes an electrostatic adsorption roller, which is rotatably disposed between the left and right outer surfaces of the U-shaped frame. A second motor is mounted on the outer surface of the U-shaped frame, and the output end of the second motor is connected to the electrostatic adsorption roller.

[0011] In some embodiments, a cutting assembly is provided between the opposite outer surfaces of the left and right sides of the U-shaped frame. The cutting assembly is used to cut the pile on the surface of the fabric. The cutting assembly includes a spiral circular blade rotatably disposed between the opposite outer surfaces of the left and right sides of the U-shaped frame. A blade holder is installed between the opposite outer surfaces of the left and right sides of the U-shaped frame. A flat blade is installed above the blade holder. A first motor is installed on the outer surface of the U-shaped frame. The output end of the first motor is connected to the spiral circular blade.

[0012] In some embodiments, the fixing frame is configured with open channels on both sides, the U-shaped frame has a strip hole on the side near the fixing frame, the inner wall of the U-shaped frame away from the fixing frame has a groove, and the front guide roller has a slider at the end away from the threaded block, the slider being slidably connected to the inside of the groove.

[0013] In some embodiments, the fixed frame has two sliding rods connected internally, and the threaded block is movably sleeved on the outer surface of the two sliding rods.

[0014] In some embodiments, two side plates are installed on both the front and rear sides of the U-shaped frame, and a support roller is rotatably connected between the two side plates.

[0015] This utility model has at least the following beneficial effects: 1. In this utility model, by pulling the pull rod, the connecting plate causes the limiting rod to disengage from the inside of the limiting hole, releasing the limiting of the fixed plate and allowing the threaded rod to rotate. This allows the position of the front guide roller to be adjusted, thereby adjusting the tension. After adjustment, the spring force causes the limiting rod to insert into the inside of the limiting hole, limiting the fixed plate and thus limiting the threaded rod. This prevents the threaded rod from rotating on its own due to vibration, thereby avoiding excessive or insufficient tension on the fabric.

[0016] 2. In this utility model, before shearing, the electrostatic adsorption roller is driven by a second motor to rotate, and the electrostatic adsorption roller adsorbs the fluff on the fabric, so that the fluff is in an upright state, which makes it easier for the subsequent cutting component to cut it.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a cutting mechanism for a textile shearing machine, including a U-shaped frame 1. A front guide roller 3 and a rear guide roller 4 are arranged between the opposite outer surfaces of the left and right sides of the U-shaped frame 1. The front guide roller 3 and the rear guide roller 4 are respectively located on the front and rear sides of the cutting assembly 2. A tension adjustment assembly 5 and a limiting assembly 6 are installed on one side of the U-shaped frame 1. The tension of the front guide roller 3 on the fabric is adjusted by adjusting the position of the front guide roller 3 through the tension adjustment assembly 5. The limiting assembly 6 is used to limit the tension adjustment assembly 5 to prevent the tension adjustment assembly 5 from working easily under external force. Two side plates are installed on both the front and rear sides of the U-shaped frame 1. A support roller 8 is rotatably connected between the two side plates. Specifically, the fabric is supported by the support roller 8. A cutting component 2 is provided between the opposite outer surfaces of the left and right sides of the U-shaped frame 1. The cutting component 2 is used to cut the pile on the surface of the fabric. The cutting component 2 includes a spiral circular blade 21 rotatably disposed between the opposite outer surfaces of the left and right sides of the U-shaped frame 1. A blade holder is installed between the opposite outer surfaces of the left and right sides of the U-shaped frame 1. A flat blade 23 is installed above the blade holder. A first motor 22 is installed on the outer surface of the U-shaped frame 1. The output end of the first motor 22 is connected to the spiral circular blade 21. Specifically, when the first motor 22 is working, the first motor 22 drives the spiral circular blade 21 to rotate. The spiral circular blade 21 and the flat blade 23 rotate relative to each other, cutting the pile on the fabric.

[0021] The fabric passes over the front support roller 8, around the front guide roller 3, and under the spiral circular knife 21 and flat knife 23. It then passes under the rear guide roller 4 and over the rear support roller 8. The first motor 22 drives the spiral circular knife 21 to rotate, and the spiral circular knife 21 and flat knife 23 rotate relative to each other, cutting the pile on the fabric.

[0022] Example 2: Based on Example 1, such as Figures 1-5 As shown, the tension adjustment assembly 5 includes a fixed frame 51 installed on one side of the U-shaped frame 1. A threaded rod 52 is rotatably connected inside the fixed frame 51, and a threaded block 53 is threadedly connected to the outer surface of the threaded rod 52. A front guide roller 3 is disposed on one side of the threaded block 53. One end of the threaded rod 52 rotatably passes through the outer surface of the fixed frame 51. A turntable 54 is disposed on the side of the threaded rod 52 outside the fixed frame 51. Specifically, by limiting the contact of the threaded rod 52, the turntable 54 is rotated, causing the threaded rod 52 to rotate. When the threaded rod 52 rotates, it causes the threaded block 53 on it to move. The threaded block 53 causes the front guide roller 3 to move, thereby adjusting the tension of the fabric.

[0023] The fixed frame 51 is configured with open channels on both sides. The U-shaped frame 1 has a strip hole on the side close to the fixed frame 51, and a groove is provided on the inner wall of the side of the U-shaped frame 1 away from the fixed frame 51. A slider is provided at the end of the front guide roller 3 away from the threaded block 53. The slider is slidably connected to the inside of the groove. Specifically, when the threaded rod 52 rotates, the threaded block 53 drives the front guide roller 3 to move, so that the slider slides inside the groove and provides space for the movement of the front guide roller 3 through the strip hole.

[0024] The fixed frame 51 has two sliding rods inside. The threaded block 53 is movably sleeved on the outer surface of the two sliding rods. Specifically, when the threaded rod 52 rotates, the threaded block 53 slides on the outer surface of the sliding rod, preventing the threaded block 53 from rotating with the threaded rod 52.

[0025] Example 3: Based on Example 1, such as Figures 1-5As shown, the limiting component 6 includes a fixed plate 65, which is sleeved on the outer surface of the threaded rod 52 located outside the fixed frame 51. Two limiting rods 62 are movably inserted into the outer surface of the fixed plate 65. A number of limiting holes 61 arranged in a circumferential array are opened on the outer surface of the fixed frame 51. One end of each of the two limiting rods 62 is movably inserted into the interior of two of the limiting holes 61. The other ends of the two limiting rods 62 are connected to connecting plates 63, which are movably sleeved on the outside of the threaded rods 52. Two springs 64 are connected between the connecting plate 63 and the fixed plate 65, and the two springs 64 are respectively sleeved on the outside of the two limiting rods 62. A pull rod 66 is connected to the outer surface of the connecting plate 63, and one end of the pull rod 66 movably passes through the outer surface of the turntable 54. Specifically, when it is necessary to adjust the tension of the fabric, by applying force to the pull rod 66 outward, the pull rod 66 drives the connecting plate 63 to move, and the connecting plate 63 drives the limiting rods 62 to move, so that the limiting hole 61 disengages from the inside of the limiting hole 61, and the springs 64... When deformation occurs, the limiting rod 62 disengages from the limiting hole 61, releasing the limiting plate. By applying force to the pull rod 66 in the circumferential direction, the pull rod 66 drives the turntable 54 to rotate. After adjustment, the limiting rod 62 rotates to the position corresponding to the limiting hole 61. When the force on the pull rod 66 stops, the spring 64 returns to its original position, driving the connecting plate 63 to return to its original position, allowing the limiting rod 62 to insert into the corresponding limiting hole 61, thereby limiting the fixed plate 65 and the threaded rod 52. This prevents the threaded rod 52 from rotating on its own due to vibration, thus avoiding excessive or insufficient tension on the fabric.

[0026] Example 4: Based on Example 1, as follows Figures 1-5 As shown, an electrostatic adsorption component 7 is provided between the opposite outer surfaces of the left and right sides of the U-shaped frame 1. The electrostatic adsorption component 7 is located above the front guide roller 3 and is used to adsorb the lint on the fabric so that it is in an upright state.

[0027] The electrostatic adsorption component 7 includes an electrostatic adsorption roller 71, which is rotatably positioned between the left and right outer surfaces of the U-shaped frame 1. A second motor 72 is mounted on the outer surface of the U-shaped frame 1, and the output end of the second motor 72 is connected to the electrostatic adsorption roller 71. Specifically, before shearing, the second motor 72 drives the electrostatic adsorption roller 71 to rotate, adsorbing the lint on the fabric and keeping the lint upright for easy cutting by the subsequent cutting component 2. The electrostatic adsorption roller 71 is a tearable electrostatic dust removal roller with multiple layers of electrostatic paper wrapped around its surface. The base material of these electrostatic papers is polyethylene film, and each layer is coated with a high-adhesion coating. There are pre-cut lines on the edge of the roller. When the electrostatic adsorption roller 71 adsorbs the fabric, lint and impurities will adhere to its surface. After the surface layer of electrostatic paper adsorbs the lint and impurities and loses its adsorption effect, the surface layer of electrostatic paper can be peeled off to expose a new layer of electrostatic paper for continued use.

[0028] Based on the above embodiments, the following is the complete working principle of the above embodiments: In use, the fabric is passed over the front support roller 8, around the front guide roller 3, and under the spiral circular cutter 21 and flat cutter 23, then around the rear guide roller 4 and over the rear support roller 8. The first motor 22 drives the spiral circular cutter 21 to rotate, causing relative rotation between the spiral circular cutter 21 and the flat cutter 23, cutting the pile on the fabric. When it is necessary to adjust the fabric tension, force is applied to the pull rod 66 outwards, causing the pull rod 66 to move the connecting plate 63. The connecting plate 63 then moves the limiting rod 62, causing the limiting hole 61 to disengage from its interior, and causing the spring 64 to deform. The limiting rod 62 then moves out of the limiting hole. After the internal part of 61 is disengaged, the limiting plate is released. By applying force to the pull rod 66 in the circumferential direction, the pull rod 66 drives the turntable 54 to rotate, the turntable 54 drives the threaded rod 52 to rotate, and the threaded rod 52 drives the threaded block 53 on it to move. The threaded block 53 drives the front guide roller 3 to move, thereby adjusting the tension of the fabric. After the adjustment is completed, the limiting rod 62 rotates to the position corresponding to the limiting hole 61, and the force applied to the pull rod 66 is stopped. At this time, the spring 64 is reset, and the spring 64 drives the connecting plate 63 to reset, so that the limiting rod 62 is inserted into the corresponding limiting hole 61, thereby limiting the fixed plate 65, and then limiting the threaded rod 52, to prevent the threaded rod 52 from rotating on its own due to vibration, thereby avoiding excessive or insufficient tension on the fabric.

[0029] Before shearing, the second motor 72 drives the electrostatic adsorption roller 71 to rotate. The electrostatic adsorption roller 71 adsorbs the fluff on the fabric, making the fluff stand upright, which is convenient for the subsequent cutting component 2 to cut it. When the electrostatic adsorption roller 71 adsorbs the fabric, fluff and impurities will stick to its surface. At this time, the outer layer of electrostatic paper is peeled off to expose a new ring of electrostatic paper for continued use.
