Description

Technical Field

[0001] This invention relates to the field of glove machine technology, and more specifically to an assembly method for a pure iron core needle selector. Background Technology

[0002] As the name suggests, a glove knitting machine is used to knit gloves. Gloves are becoming increasingly widely used, and the demands on gloves in daily life are also rising, with various patterns and styles becoming essential. This places higher demands on glove knitting machines. Manufacturers also want glove knitting machines capable of knitting gloves with various patterns and styles, and with convenient operation and adjustment. Currently, most glove knitting machines on the market use mechanical roller needle selectors. These roller needle selectors arrange pins on a needle drum, and the distribution of the pins depends on the type of glove being knitted. Furthermore, each needle drum only has one arrangement. When the knitting shape or color of the glove needs to be changed, the arrangement must be changed again, resulting in drawbacks such as complex operation, high cost, and limited color options for the knitted gloves.

[0003] Currently, there is no efficient assembly method available on the market for electromagnet- and spring-pin adsorption-type needle selectors. During the installation and debugging of glove machines, the spring needles need to be attracted to the electromagnets according to the knitting requirements to achieve knitting at a specific point on the glove. The adsorption and separation relationship between the spring needles and the electromagnets needs to be repeatedly adjusted during the assembly process. There is currently no complete assembly method on the market to ensure the stability of the cooperation (adsorption and separation) between the electromagnets and spring needles. Summary of the Invention

[0004] To address the above shortcomings, the technical problem to be solved by the present invention is to provide an assembly method for a pure iron core needle selector, which is used to assemble an electromagnet and a spring needle to ensure the stability of the electromagnet and the spring needle's attraction during operation.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0006] An assembly method for a pure iron core needle selector includes the following steps;

[0007] Step 1: Assemble the electromagnet and the modular mounting base;

[0008] Step 2: Securely install the glove machine needle plate onto the modular mounting base;

[0009] Step 3: String multiple spring pins together on the same connecting rod;

[0010] Step 4: Install the support foot of the spring needle into the needle groove of the glove machine needle plate, and then pre-fix the connecting rod to the glove machine needle plate;

[0011] Step 5: With the power off, vibrate the needle selector and observe whether any spring needles are attracted to the electromagnet. If no spring needles are attracted to the electromagnet, proceed to the next step. If spring needles are attracted to the electromagnet, adjust the relative position of the connecting rod and repeat this operation.

[0012] Step 6: With the power off, press the spring pins in sequence. If all the spring pins can be attracted to the electromagnet, tighten the connecting rod. If some spring pins cannot be attracted to the electromagnet, adjust the position of the connecting rod until all the spring pins can be attracted to the electromagnet.

[0013] As a preferred embodiment of the present invention, step one further includes the following steps:

[0014] (1.1) Install the electromagnet in the modular mounting base and install a permanent magnet below the modular mounting base;

[0015] (1.2) Vibration-assembled fixing base, which attracts the electromagnet to the permanent magnet;

[0016] (1.3) Fix the assembled fixing base.

[0017] As a preferred embodiment of the present invention, step two further includes the following steps.

[0018] (2.1) Pre-tighten the needle plate of the glove machine onto the connecting seat of the modular fixing base;

[0019] (2.2) Align the needle slots on the needle plate of the glove machine with the electromagnets on the modular mounting base one by one;

[0020] (2.3) Lock the glove machine needle plate and the modular fixing seat.

[0021] As a preferred embodiment of the present invention, the adjustment of the connecting rod in steps five and six includes adjustment along the length of the needle groove and adjustment along the direction perpendicular to the needle plate of the glove machine.

The spring needle adsorption assembly is fixedly installed in the modular fixed base. The spring needle adsorption assembly includes an electromagnet and a permanent magnet (4). The electromagnet extends out of one end of the modular fixed base, and the permanent magnet abuts against the other end of the electromagnet.

[0032] The present invention will now be further described with reference to the accompanying drawings.

[0033] The assembly method of this pure iron core needle selector is applicable to the needle selector of glove machines. The needle selector of the glove machine includes a modular fixed base 1 and a spring needle adsorption assembly 2. The spring needle adsorption assembly 2 is fixedly installed in the modular fixed base 1. The spring needle adsorption assembly 2 includes an electromagnet 3 and a permanent magnet 4. The electromagnet 3 extends out of one end of the modular fixed base 1, and the permanent magnet 4 abuts against the other end of the electromagnet 3. The electromagnet 3 and the permanent magnet 4 cooperate to fix and separate the spring needle 20, so as to achieve the purpose of quick needle selection and quick change of pattern. Moreover, the structure of this needle selector is simpler and easier to assemble.

[0034] The electromagnet 3 includes an iron rod 5 and a coil 6. The coil 6 is sleeved on the outside of the iron rod 5. One end of the iron rod 5 extends out of one end of the splicing fixing base 1. The permanent magnet 4 is abutted against the other end of the iron rod 5. By setting the permanent magnet 4, it is convenient to combine and cancel the magnetic field of the permanent magnet 4 and the magnetic field of the electromagnet 3 when it is necessary to separate the spring needle 20.

[0035] The iron rod 5 has a snap-fit ​​groove 8 formed on it, and a limiting boss 7 is fixedly connected to the iron rod 5. The limiting boss 7 and the snap-fit ​​groove 8 are adapted to the splicing fixing seat 1. The iron rod 5 is fixed by the snap-fit ​​groove 8 and the limiting boss 7, which facilitates the installation efficiency of the iron rod 5 and prevents the iron rod 5 from moving relative to each other.

[0036] An adapter plate 9 is fixedly connected to the outside of the iron rod 5. The end of the coil 6 is fixedly connected to the adapter plate 9. A control connection line 10 is fixedly connected to the adapter plate 9. The adapter plate 9 is a PCB board. The coil wire end is first soldered to the PCB board. One end of the control connection line 10 is then soldered to the PCB board, and the other end passes through the wire hole 16 of the fixing seat and can be soldered to the control board 19.

[0037] The modular fixing base 1 includes a fixing cover 11 and a fixing base 12 that are assembled together. The fixing cover 11 has a first fixing groove 13 formed on it, and the fixing base 12 has a second fixing groove 14 formed on it. The electromagnet 3 is adapted to the first fixing groove 13 and the second fixing groove 14 respectively. The first fixing groove 13 and the second fixing groove 14 are staggered, which makes it easy to arrange the electromagnets in two rows in a staggered manner to solve the problem of the needle pitch being too small.

[0038] A fixing head 15 is formed between adjacent first fixing slots 13. The fixing head 15 extends into the second fixing slot 14. Similarly, a fixing head 15 is also formed between adjacent second fixing slots 14. The fixing head 15 extends into the first fixing slot 13 to fix the electromagnet 3 and facilitate the fixing and snapping of the iron rod 5 of the electromagnet.

[0039] Both the fixed cover 11 and the fixed base 12 have wire holes 16 formed on them, so that the control connection wire 10 can extend out of the assembled fixed base 1 and connect to the control board 19.

[0040] A connecting seat 17 is fixedly connected to the lower end face of the fixed base 12, so that the needle selector of this glove machine can be fixedly installed on the needle plate 21 of the glove machine through the connecting seat 17.

[0041] A magnetic pressure plate 18 is fixedly installed on one end face of the modular mounting base 1. The permanent magnet 4 is fixedly installed on the modular mounting base 1 through the magnetic pressure plate 18. A control plate 19 is fixedly installed on the magnetic pressure plate 18. The control plate 19 is fixedly connected to the electromagnet 3. The direction of the current of the electromagnet 3 is controlled by the control plate 19, so as to facilitate changing the direction of the magnetic field of the electromagnet 3.

[0042] To facilitate the installation of spring needles, multiple needle grooves 22 are evenly arranged inside the needle plate 21 of the glove machine, and spring needles 20 are installed in the needle grooves 22.

[0043] The end of the spring needle 20 is formed with a mounting hole 23. The mounting holes 23 between adjacent spring needles 20 are connected by a connecting rod, fixing one end of the spring needle 20 to the needle plate 21 of the glove machine. The other end of the spring needle 20 is adapted to the battery iron 3, and the end is attracted by the electromagnet. The lower end of the spring needle 20 is connected to a support foot 24, which is placed in the needle groove 22. The support foot 24 supports the end of the spring needle 20 to prevent the end of the spring needle 20 from being attracted by the electromagnet.

[0044] The assembly method of this pure iron core needle selector includes the following steps;

[0045] Step 1: Assemble the electromagnet and the modular mounting base;

[0046] Step 2: Securely install the glove machine needle plate onto the modular mounting base;

[0047] Step 3: String multiple spring needles together on the same connecting rod, and fix the spring needles to the needle plate of the glove machine through the connecting rod. This makes it easier to adjust all the spring needles at the same time, improving assembly and debugging efficiency.

[0048] Step 4: Separate the multiple spring needles so that each spring needle corresponds to a needle slot. Install the support foot of the spring needle into the needle slot of the glove machine needle plate, and then pre-fix the connecting rod to the glove machine needle plate so that each spring needle can work independently.

[0049] Step 5: With the power off, slightly vibrate the needle selector (simulating the vibration generated by the glove machine) and observe whether any spring needles are attracted to the electromagnet. If no spring needles are attracted to the electromagnet, proceed to the next step. If spring needles are attracted to the electromagnet, adjust the relative position of the connecting rod used to connect the spring needles and repeat this operation to eliminate the potential risk of spring needles being accidentally attracted due to the vibration generated by the glove machine.

[0050] In this embodiment, the relative position of the connecting rod is adjusted by using fixed bases of different heights to adjust the installation position of the connecting rod.

[0051] Step 6: With the power off, press the spring pins in sequence. If all the spring pins can be attracted to the electromagnet, tighten the connecting rod. If some spring pins cannot be attracted to the electromagnet, adjust the position of the connecting rod until all the spring pins can be attracted to the electromagnet, ensuring that the spring pins can be attracted to the electromagnet when the power is off.

[0052] In this assembly method, the position of all spring pins is changed simultaneously by altering the relative position of the connecting rod used to connect each spring pin in series, thereby improving adjustment efficiency.

[0053] Because a permanent magnet is installed below the electromagnet, the iron core is magnetized by the permanent magnet, which makes the iron core have a certain magnetism, thereby attracting and fixing the spring needle.

[0054] There are two ways to attach the spring needle to the electromagnet: (1) By energizing the electromagnet, the magnetism of the electromagnet is enhanced, thereby attracting the suspended spring needle to the electromagnet. This method of attraction requires a large magnetism of the electromagnet and has poor stability; (2) By moving the spring needle, the spring needle is attracted to the electromagnet, ensuring the stability of the electromagnet in attracting the spring needle. Therefore, in this assembly method, the method of manual pressing is used to test whether the spring needle can be attracted to the electromagnet without power, so as to ensure the working stability of the needle selector.

[0055] Step one also includes the following steps,

[0056] (1.1) Install the electromagnet in the modular mounting base and install a permanent magnet below the modular mounting base to magnetize the core of the electromagnet;

[0057] (1.2) Vibration-fitting fixed base, ensuring that the iron core of the electromagnet inside the fixed base is attracted to the permanent magnet;

[0058] (1.3) Fix the assembled fixing base.

[0059] Step two also includes the following steps to ensure that the installation position of the spring pin corresponds to the position of the electromagnet, and to ensure that the spring pin is attracted to the electromagnet.

[0060] (2.1) Pre-tighten the needle plate of the glove machine onto the connecting seat of the modular fixing base;

[0061] (2.2) Align the needle slots on the needle plate of the glove machine with the electromagnets on the modular mounting base one by one;

[0062] (2.3) Lock the glove machine needle plate and the modular fixing seat.

[0063] As a preferred embodiment of the present invention, the adjustment methods of the connecting rod in steps five and six include adjustment along the length direction of the needle groove and adjustment along the direction perpendicular to the needle plate of the glove machine.

[0064] The glove machine needle selector is fixedly mounted on the glove machine needle plate 21 via a modular mounting base 1. During the magnetization process of the electromagnet 3, the spring needle 20 of the glove machine is fixedly attracted to the electromagnet 3 by the magnetic field generated by the electromagnetic coil. During the demagnetization process of the electromagnet 3, the current direction in the electromagnet 3 is opposite to the magnetization direction, so that the magnetic field generated by the electromagnet 3 cancels out the magnetic field generated by the permanent magnet 4, thereby demagnetizing and separating the spring needle 20 from the electromagnet.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention; therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
