Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of needle processing, and in particular to a needle straightening device. Background Technology
[0002] The straightening mechanism used in needle production is used to straighten the shaft area of the needle to ensure its flatness. Needles are widely used in nonwoven fabric production. Needle-punched nonwoven fabric accounts for 28% to 30% of the nonwoven fabric production line. The needle-punched nonwoven fabric process includes pre-punching, main punching, patterned needle punching, ring punching, and tubular needle punching, which requires repeated puncture of the nonwoven fabric.
[0003] The prior art Chinese utility model patent with application number CN202220389610.5 relates to a straightening mechanism for needle production, including a side frame, a stamping rod, a first wheel frame, an adjusting head, a screw, an upper straightening wheel, a support leg, and a guide groove, which can perform straightening operations on needles.
[0004] However, in actual use, the above-mentioned device does not have the ability to rotate the needle and straighten the needle in different bending directions. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a needle straightening device that uses a reciprocating device in conjunction with a straightening device to straighten needles. The straightening device is adapted to different types of needles, and a fixing device fixes one end of the needle to prevent the needle displacement from affecting the straightening process, thereby improving the practicality of the device.
[0006] This utility model discloses a needle straightening device, comprising a reciprocating device, a straightening device, and a fixing device. The straightening device is mounted on the reciprocating device, and the fixing device is mounted on the reciprocating device. The reciprocating device works in conjunction with the straightening device to straighten the needle. The straightening device is adapted to different types of needles. The fixing device fixes one end of the needle to prevent the needle's own displacement from affecting the straightening process, thus improving the practicality of the device.
[0007] Preferably, the reciprocating device includes a base plate, a support frame, support rods, a transverse frame, and straight nuts. Multiple sets of support rods are mounted on the upper surface of the base plate via the support frame. The multiple sets of support rods pass through the four corner positions of the transverse frame via straight nuts. The multiple sets of support rods and straight nuts work together to provide support and limit the movement of the transverse frame, thereby facilitating the reciprocating movement of the transverse frame to cooperate with the straightening device to straighten the needle, thus improving the practicality of the device.
[0008] Preferably, the straightening device includes a dual-output reducer, a motor, a U-shaped frame, straightening wheels, and a double-acting screw. The dual-output reducer is mounted on the upper part of the transverse frame, and the motor is mounted on the top of the dual-output reducer. A set of output ends is provided on the left and right sides of the lower end face of the dual-output reducer, and a set of double-acting screws is connected to each of the two sets of output ends. A set of U-shaped frames is installed both above and below the transverse frame, and straightening wheels are mounted on the U-shaped frames. The left and right sides of the U-shaped frames are connected to the double-acting screws via nuts. Turning on the motor transmits power through the dual-output reducer to the two sets of double-acting screws, causing them to rotate. This causes the upper and lower sets of U-shaped frames to move towards or away from each other, thereby adjusting the spacing of the two sets of straightening wheels to accommodate straightening operations for needles of different diameters, thus improving the practicality of the device.
[0009] Preferably, the device also includes handles, with a set of handles installed at an angle on the left and right sides of the front end face of the transverse frame; the two sets of handles make it easy for the operator to hold and control the transverse frame to move back and forth, complete the straightening operation of the needle, and improve the practicality of the device.
[0010] Preferably, the device also includes a reducer, a drive motor, and a needle fixing sleeve. The reducer is installed at the rear of the support frame, the drive motor is installed on the reducer, and the needle fixing sleeve is installed on the rotating end of the reducer. The needle fixing sleeve fixes the end of the needle. The drive motor is turned on and transmits power through the reducer to the needle fixing sleeve, which drives the needle on the needle fixing sleeve to rotate. This facilitates the straightening device to straighten the needle and improves the practicality of the device.
[0011] Preferably, the fixing device includes a clamping groove, a pressure plate, a bearing, and a bearing seat. The clamping groove is provided on the inner side of the needle fixing sleeve, the pressure plate is located inside the clamping groove, and the bearing seat is connected to the outer side of the pressure plate through the bearing. The bearing seat is connected to the needle fixing sleeve through a nut and extends through the needle fixing sleeve to the outside of the needle fixing sleeve. After the needle tip is inserted into the needle fixing sleeve, the bearing seat is rotated to push the pressure plate to clamp the needle tip, thereby fixing the position of the needle and improving the practicality of the device.
[0012] Preferably, it also includes fastening bolts, with two sets of fastening bolts provided on the outer side of the pressure plate. The fastening bolts extend through the needle fixing sleeve to the outside of the needle fixing sleeve; the lateral movement of the pressure plate is limited by the fastening bolts, which improves the stability and practicality of the device.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the reciprocating device is used in conjunction with the straightening device to straighten the needle, the straightening device is adapted to different types of needles, and the fixing device fixes one end of the needle to prevent the needle displacement from affecting the straightening process, thereby improving the practicality of the device.
