Description

Technical Field

[0001] This utility model relates to the field of circular knitting machine technology, specifically to a fabric splitting mechanism for a circular knitting machine. Background Technology

[0002] Circular knitting machines, also known as circular weft knitting machines, have developed rapidly and gained widespread use due to their numerous loop-forming systems, high speed, high output, rapid pattern changes, good fabric quality, fewer processes, and strong product adaptability.

[0003] The circular knitting machine weaves the fabric. The woven fabric is then held and pulled by two winding rollers of the winding machine's traction mechanism, and then wound onto the take-up roller of the winding machine. Between the weaving mechanism and the winding rollers are an expanding frame, a cutting mechanism, and a supporting frame. The cutting mechanism is fixed to the winding machine frame. During operation, the woven fabric falls in a cylindrical shape under the traction of the traction mechanism. After being expanded by the expanding frame, the fabric changes from a cylindrical shape to a layered shape. When the fabric passes between the cutting blade and the guide block of the cutting mechanism, it is cut open by the cutting blade. The cut fabric is then slowly unfolded by the V-shaped expanding and supporting frame, and finally wound up by the take-up roller. A microswitch is located below the cutting blade. When the microswitch is triggered, it sends an alarm signal to shut down the machine.

[0004] The inventors of this application have discovered that in current fabric cutting mechanisms, the fabric cutting blade and guide block are fixedly installed. When problems such as blade wear or motor failure prevent the fabric from being cut, the fabric continues to be pulled downwards under the action of the traction mechanism until it contacts the micro switch below. This response is slow and easily damages the fabric. Moreover, when the thickness of the woven fabric increases, the thicker fabric will get stuck between the fabric cutting blade and the guide block, causing the fabric cutting blade to jam and unable to rotate. At the same time, the fabric cannot go down. In this case, the micro switch will not work, causing the machine to be unable to stop, which can lead to serious consequences. Utility Model Content

[0005] The purpose of this utility model is to provide a fabric splitting mechanism for a large circular knitting machine to solve the problems mentioned above in the background art.

[0006] This utility model embodiment provides a fabric slitting mechanism for a large circular knitting machine, including: a mounting base, a slitting component, a guide block, a first fixed base, and a micro switch;

[0007] The mounting base is installed on the fabric support frame of the fabric rolling machine;

[0008] The first fixed seat is rotatably mounted on the mounting base via a shoulder screw, and the guide block is mounted on the first fixed seat;

[0009] The guide block is provided with a first guide surface and a second guide surface connected together, the included angle between the first guide surface and the second guide surface is an obtuse angle, and the guide block is provided with a groove on the guide surface;

[0010] The cutting assembly includes: a drive motor and a circular blade;

[0011] The drive motor is mounted on the mounting base, the circular blade is mounted on the output shaft of the drive motor, and the cutting edge of the circular blade is embedded in the groove. The drive motor is used to drive the circular blade to rotate.

[0012] The micro switch is mounted on the mounting base, and the contact piece of the micro switch is located below the guide block and adjacent to the bottom surface of the guide block;

[0013] The fabric passes sequentially through the first guide surface and the second guide surface of the guide block, and the circular blade is used to cut the fabric when it rotates;

[0014] When the guide block rotates, it contacts the contact piece of the micro switch, causing the micro switch to emit an alarm signal.

[0015] Based on the above scheme, the fabric slitting mechanism for the large circular knitting machine of this utility model comprises a mounting base, a slitting component, a guide block, a first fixed base, and a micro switch. The mounting base is mounted on the fabric support frame of the fabric winding machine, the first fixed base is rotatably mounted on the mounting base, and the guide block is mounted on the first fixed base. The guide block has a groove on its guide surface. The slitting component includes a drive motor and a circular blade. The circular blade is mounted on the output shaft of the drive motor, and its cutting edge is embedded in the groove of the guide block. The micro switch is mounted on the mounting base, located below the guide block. In this fabric slitting mechanism for the large circular knitting machine of this utility model, the fabric woven by the weaving mechanism is guided by the traction mechanism and passes through the first and second guide surfaces of the guide block. When passing the circular blade, the rotating circular blade slits the fabric. If the fabric fails to slit due to a malfunction, the fabric continues to move downward (fall) under the action of the traction mechanism. The fabric exerts downward pressure on the guide block, causing the guide block to rotate. When the guide block rotates to a certain angle, its bottom surface contacts the contact piece of the micro switch, triggering the micro switch. The micro switch then sends an alarm signal to the controller, which promptly shuts down the equipment to ensure its safety. The micro switch senses the rotation of the guide block, eliminating the need for fabric to fall and thus providing a more timely alarm. It is also suitable for fabrics of varying thicknesses.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0051] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0052] As described in the background section of this application, the woven fabric falls in a cylindrical shape under the traction of the traction mechanism. After being expanded by the spreader, the fabric changes from a cylindrical shape to a layered shape. When the fabric passes between the spreader blade and the guide block of the spreader mechanism, the spreader blade cuts the fabric. The cut fabric is then slowly unfolded by the V-shaped spreader and finally wound up by the take-up roller. A microswitch is located below the spreader blade. When the microswitch is triggered, it sends an alarm signal to shut down the machine.

[0053] The inventors of this application have discovered that in current fabric cutting mechanisms, the fabric cutting blade and guide block are fixedly installed. When problems such as blade wear or motor failure prevent the fabric from being cut, the fabric continues to be pulled downwards under the action of the traction mechanism until it contacts the micro switch below. The alarm response is slow and the fabric is easily damaged. Moreover, when the thickness of the woven fabric increases, the thicker fabric will get stuck between the fabric cutting blade and the guide block, causing the fabric cutting blade to jam and not rotate. At the same time, the fabric cannot go down. In this case, the micro switch will not work, causing the machine to be unable to stop, which will lead to serious consequences.

[0054] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows:

Figure 10 This is a schematic diagram of the second state of the fabric cutting mechanism in another angle in an embodiment of this utility model.

[0056] like Figures 1 to 10 As shown, the fabric slitting mechanism for the large circular knitting machine in this embodiment includes: a mounting base 1, a slitting component, a guide block 3, a first fixed base 4, and a micro switch 5.

[0057] Mounting base 1 includes: a base plate 11 and multiple vertical plates 12, the multiple vertical plates 12 are vertically arranged on the base plate 11, and the base plate 11 of mounting base 1 is fixed to the connecting plate of the fabric support frame 100.

[0058] The first fixed seat 4 is rotatably mounted on the vertical plate 12 of the mounting base 1 via a shoulder screw 41, and the guide block 3 is fixedly mounted on the first fixed seat 4. When pressure is applied, the guide block 3 drives the first fixed seat 4 to rotate relative to the mounting base 1.

[0059] The guide block 3 has a first guide surface 31 and a second guide surface 32 that are connected to each other. The first guide surface 31 and the second guide surface 32 of the guide block 3 both protrude from the first fixed seat 4, and the first guide surface 31 and the second guide surface 32 are both obliquely downward. The second guide surface 32 is located obliquely below the first guide surface 31, and the included angle between the first guide surface 31 and the second guide surface 32 is an obtuse angle.

[0060] The guide block 3 has a groove 301 on the first guide surface 31 and the second guide surface 32.

[0061] The slitting assembly includes a drive motor 21 and a circular blade 22.

[0062] The drive motor 21 is mounted on the vertical plate 12 of the mounting base 1. The circular blade 22 is fixedly mounted on the output shaft of the drive motor 21 through a connector, and the cutting edge of the circular blade 22 is embedded in the groove 301 of the guide block 3. The drive motor 21 is used to drive the circular blade 22 to rotate.

[0063] The micro switch 5 is mounted on the vertical plate 12 of the mounting base 1. The contact piece 51 of the micro switch 5 is located below the guide block 3, and there is a small distance between the contact piece 51 and the bottom surface of the guide block 3.

[0064] In this embodiment, as Figure 8 As shown, the fabric 200 woven by the weaving mechanism is pulled by the traction mechanism and then passes through the first guide surface and the second guide surface of the guide block in sequence after being guided. When the fabric 200 passes through the second guide surface and the circular blade, the rotating circular blade cuts the fabric.

[0065] like Figure 9 and Figure 10 As shown, when the fabric cutting mechanism malfunctions and fails to cut the fabric 200, the fabric continues to move downwards (fall) under the action of the traction mechanism. The fabric exerts downward pressure on the second guide surface of the guide block, causing the guide block to rotate. The circular blade separates from the guide block, creating a gap approximately equal to the thickness of the fabric between the circular blade and the guide block. When the guide block rotates to a certain angle, the bottom surface of the guide block contacts the contact piece of the micro switch. The guide block triggers the micro switch, which sends an alarm signal to the controller, allowing the controller to promptly shut down the equipment and ensure its safety.

[0066] As can be seen from the above, the fabric slitting mechanism for the circular knitting machine in this embodiment comprises a mounting base, a slitting component, a guide block, a first fixed base, and a micro switch. The mounting base is mounted on the fabric support frame of the fabric winding machine, the first fixed base is rotatably mounted on the mounting base, and the guide block is mounted on the first fixed base. The guide block has a groove on its guide surface. The slitting component includes a drive motor and a circular blade. The circular blade is mounted on the output shaft of the drive motor, and its cutting edge is embedded in the groove of the guide block. The micro switch is mounted on the mounting base, located below the guide block. In this embodiment, the fabric woven by the knitting mechanism is guided by the traction mechanism and passes through the first and second guide surfaces of the guide block. When passing the circular blade, the rotating blade slits the fabric. If the fabric fails to slit due to a malfunction, the fabric continues to move downwards (fall) under the action of the traction mechanism. The fabric exerts downward pressure on the guide block, causing it to rotate. When the guide block rotates to a certain angle, its bottom surface contacts the contact piece of the micro switch, triggering the micro switch. The micro switch then sends an alarm signal to the controller, which promptly shuts down the equipment to ensure its safety. The micro switch senses the rotation of the guide block, eliminating the need for fabric to fall and thus providing a more timely alarm. It is also suitable for fabrics of varying thicknesses.

[0075] The adjusting bolt 81 engages with the first threaded hole of the crossbar 72, and the end face of the adjusting bolt 81 abuts against the end face of the spring 6.

[0076] In this embodiment, the adjusting bolt abuts against the end face of the spring. Rotating the adjusting bolt can adjust the tension of the spring, thereby adjusting the spring force as needed to adjust the sensitivity of the guide block rotation.
