Description

Technical Field

[0001] This utility model relates to the technical field of needle manufacturing, and in particular to a non-woven needle fixed-length cutting device. Background Technology

[0002] The processing of nonwoven needles requires drawing and stamping to obtain a cylindrical blank, which is then cut into needle blanks of appropriate length by a cutting device. The needle blanks are then polished to obtain the needles. In the prior art, utility model patent application number 201921694998.4 discloses a fixed-length cutting device for flat knitting machine needle production. This device mainly consists of a fixed plate, a clamping plate, and a cutting tool. The fixed plate has needle holes. When cutting the blank, the blank is placed in the needle holes of the fixed plate, then clamped and fixed by the clamping plate, and finally cut by the cutting tool to obtain needle blanks of appropriate length. The cut needle blanks can then be removed from the needle holes by the operator. However, this device has the following problems: after cutting the blank, the operator still needs to manually remove the cut needle blanks from the needle holes of the fixed plate and collect them, which is inconvenient and makes needle blank collection difficult. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a non-woven needle length cutting device that automatically collects the cut needle blanks by means of a collection mechanism, which facilitates the collection of needle blanks, is easy to use, and has high practicality.

[0004] This utility model discloses a nonwoven needle fixed-length cutting device, comprising a base plate, a support plate, a lifting frame A, and an electric hydraulic clamp. The support plate is fixedly installed on the upper part of the base plate, and the electric hydraulic clamp is fixedly installed below the lifting frame A, located on the right side of the support plate. It also includes a fixing plate, a feeding mechanism, a positioning mechanism, and a collecting mechanism. The fixing plate is fixedly installed on the upper part of the support plate and has left and right communicating positioning holes. The collecting mechanism is located below the electric hydraulic clamp. The feeding mechanism is installed on the support plate and has a feeding function. The positioning mechanism is located on the right side of the electric hydraulic clamp and has a positioning function. The function is as follows: the hoisting frame A is fixedly installed on the support in the workshop; when cutting the blank, the blank is passed through the positioning hole on the fixed plate, and then the feeding mechanism moves the blank to the right until the right end of the blank contacts the positioning mechanism. Then the electric hydraulic clamp is opened to cut the blank. After the blank is cut, it falls into the collection mechanism. Then the feeding mechanism continues to feed the blank to the right until the right end of the blank contacts the positioning mechanism again, and then the blank is cut again. The collection mechanism automatically collects the cut needle blanks, which is convenient to collect, easy to use, and highly practical.

[0005] Preferably, the feeding mechanism includes a base frame, two sets of rollers A, a drive motor, two sets of rollers B, a mounting frame, a lifting rod, a cylinder, and a fixed frame. The base frame is fixedly mounted on a base plate. Both sets of rollers A are rotatably mounted on the base frame. The drive motor is fixedly mounted on the base frame, and its output end is connected to one set of rollers A. The two sets of rollers B are located above the two sets of rollers A, and both sets of rollers B are rotatably mounted on the mounting frame. The mounting frame is fixedly mounted on the lower end of the lifting rod, and the upper end of the lifting rod is connected to the output end of the cylinder. The cylinder is fixedly mounted on the fixed frame. At the top of the frame, the lifting rod slides up and down on the fixed frame, which is fixedly mounted on the support plate. When feeding the billet, the billet is placed on two sets of rollers A, and the right side of the billet passes through the positioning hole of the fixed plate. Then, the cylinder is opened, and the cylinder drives the mounting frame through the fixed frame to lower the two rollers B, so that the two sets of rollers B contact the upper end of the billet. Then, the drive motor is turned on, and the drive motor drives one of the rollers A to rotate. The rotating roller A conveys the billet to the right, so that the right end of the billet contacts the positioning mechanism; this facilitates the movement of the billet.

[0006] Preferably, the positioning mechanism includes a lifting frame B, a hydraulic cylinder, a moving rod, and a positioning plate. The hydraulic cylinder is fixedly mounted on the lifting frame B, and the moving rod is slidably mounted on the lifting frame B. The right end of the moving rod is connected to the output end of the hydraulic cylinder. The positioning plate is fixedly mounted on the left end of the moving rod and is located to the right of the electric hydraulic clamp. The lifting frame B is fixedly mounted on the support frame in the workshop. When cutting the blank, the first piece is measured, the hydraulic cylinder is opened, and the hydraulic cylinder drives the moving rod to move the positioning plate. When the right end of the blank contacts the positioning plate, the distance between the electric hydraulic clamp and the positioning plate is the required blank length, thus determining the position of the positioning plate. Then, the positioning plate is fixed. When cutting subsequent blanks, the right end of the blank is moved to contact the positioning plate to complete the positioning of the blank; this facilitates the cutting of the blank.

[0007] Preferably, the collecting mechanism includes a collecting box and an adjusting mechanism. The collecting box is located below the electric hydraulic clamps and has a chamber inside. The upper end of the collecting box is open. The collecting box is located below the adjusting mechanism, which is also located below the electric hydraulic clamps. The adjusting mechanism has the function of adjusting the posture of the needle blank. After the blank is cut by the electric hydraulic clamps, the cut-off needle blank is adjusted to a suitable posture by the adjusting mechanism. Then, the needle blank falls into the chamber of the collecting box in a specified posture, making the needle blanks more neatly arranged in the collecting box and facilitating the collection of the needle blanks.

[0008] Preferably, the adjustment mechanism includes two sets of support mechanisms, an adjustment box, and a vibration motor. The vibration motor is mounted on the adjustment box, and the front and rear parts of the adjustment box are respectively mounted on the two sets of support mechanisms. The adjustment box has a trapezoidal cavity, and the lower part of the adjustment box has a slot communicating with the cavity. The adjustment box is located above the collection box. The width of the slot on the adjustment box is the same as the width of a needle blank. After the needle blank is cut on the billet, the needle blank falls into the adjustment box. Then, the vibration motor is turned on, and the vibration motor drives the adjustment box to vibrate, so that the needle blank adjusts its posture in the adjustment box until the posture of the needle blank is consistent with the shape of the slot in the adjustment box. Then, the needle blank falls into the collection box through the slot at the bottom of the adjustment box for collection, so that multiple needle blanks are arranged more neatly in the collection box.

[0009] Preferably, the support mechanism includes a fixed frame, a vertical plate, a fixed column, a sliding column, and a spring. The vertical plate is fixedly installed on the upper end of the fixed frame, the fixed column is fixedly installed on the vertical plate, the sliding column is slidably installed on the fixed column, one end of the spring is fixedly installed on the vertical plate, the adjustment box is fixedly installed on the other end of the spring, and the adjustment box is fixedly installed on the sliding column. When the needle blank falls into the adjustment box, the vibration motor is turned on. The inertia generated by the vibration motor drives the adjustment box to vibrate back and forth, thereby promoting the movement of the needle blank in the adjustment box and facilitating the adjustment of the needle blank's posture.

[0010] Preferably, the inner wall of the adjustment box is provided with a wear-resistant coating.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the cut needle blank is automatically collected by the collecting mechanism, which facilitates the collection of needle blanks, is convenient to use, and has high practicality.
