Description

Technical Field

[0001] The utility model relates to the technical field of textile processing, in particular to a highly reliable and easily installed large circular knitting machine needle cylinder. Background Technique

[0002] A large circular knitting machine, scientifically named a circular weft knitting machine, is a commonly used device in textile production. Due to the large number of loop-forming systems of the large circular knitting machine, high rotational speed, high output, fast pattern change, good fabric quality, few processes, and strong product adaptability, it has developed rapidly. A needle cylinder needs to be placed at the central position of the large circular knitting machine, and textile needles are installed on the needle cylinder to form a loop-forming system;

[0003] Since a large number of textile needles are installed on the needle cylinder and often need to be replaced or repaired, at this time, the needle cylinder needs to be disassembled and installed from the large circular knitting machine.

[0004] In the prior art, a Chinese patent with the publication number of CN221645219U discloses a large circular knitting machine needle cylinder, which includes a needle cylinder body and a needle cylinder base. A connecting ring is arranged at the lower end of the needle cylinder body, and a connecting groove is opened on the needle cylinder base. The connecting ring is inserted into the connecting groove. The connecting groove is divided into an upper ring groove and a lower ring groove. A plurality of fixing mechanisms are arranged at equal angles in the circumferential direction of the upper ring groove. The fixing mechanisms are used to fix the needle cylinder body. A lifting mechanism is arranged on the needle cylinder body for lifting the needle cylinder body. For this large circular knitting machine needle cylinder, a lifting mechanism is arranged on the needle cylinder body for lifting the needle cylinder body, which is convenient for the lifting and replacement of the needle cylinder body. A connecting ring is arranged at the lower end of the needle cylinder body, and a corresponding connecting groove is opened on the needle cylinder base. The connecting ring is clamped into the connecting groove, and then the needle cylinder body is fixed through the fixing mechanism. The installation is convenient and the fixing efficiency is high.

[0005] Combined with the above materials, it can be seen that in the prior art, bolts are generally used to install and fix the needle cylinder. However, in the actual use process, multiple bolts are required to maintain the symmetry of the fixation, and all multiple bolts need to be manually tightened or disassembled, which is time-consuming and laborious. Content of the Utility Model

[0006] The purpose of the utility model is to provide a highly reliable and easily installed large circular knitting machine needle cylinder to solve the problem of cumbersome installation caused by the bolt fixation method in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A highly reliable and easily installed large circular knitting machine needle cylinder, including a large circular knitting machine needle cylinder main body in a cylindrical structure, the needle cylinder main body is installed above an installation base, and further includes:

[0008] An inner limit plate and an outer limit plate are fixedly mounted on the upper surface of the mounting base, and the inner limit plate is arranged as an annular structure, and the outer limit plate is arranged as an inner sheet structure with equal spacing, and a positioning mechanism for positioning the syringe body is arranged between the inner limit plate and the outer limit plate;

[0009] Four lower fixing plates are fixedly installed at equal intervals on the outer surface of the lower end of the syringe body, and the positions of the lower fixing plates correspond to the upper fixing plates to achieve quick installation.

[0010] Preferably, the upper fixing plate is fixedly mounted on the connecting ring, and a sliding structure is formed between the connecting ring and a sliding groove provided on the outer surface of the mounting base, and the position of the upper fixing plate is adjusted by sliding the connecting ring in the sliding groove.

[0011] Preferably, an upper magnetic block is fixedly mounted on the lower surface of the upper fixing plate, and a lower magnetic block is fixedly mounted on the upper surface of the lower fixing plate.

[0012] Preferably, the upper magnetic block and the lower magnetic block have opposite magnetic poles and are fixed to each other by adsorption, and the magnetic adsorption effect between the upper magnetic block and the lower magnetic block is used to assist in the fixation of the upper fixing plate and the lower fixing plate.

[0013] Preferably, the positioning mechanism includes a first positioning hole formed on the inner limiting plate and a second positioning hole formed on the outer limiting plate.

[0014] Preferably, the position of the first positioning hole and the position of the second positioning hole correspond to each other inside and outside, and a positioning ball is fixedly installed at the lower end of the syringe body, and the positioning ball is snap-fitted and connected to the first positioning hole and the second positioning hole. The positioning ball is made of rubber material, and the soft positioning ball is squeezed and snapped into the positioning hole to achieve the positioning effect and avoid installation misalignment.

[0015] Preferably, protective pads are fixedly attached to the outer surfaces of the inner limit plate and the outer limit plate, and the protective pads are made of soft silicone material, so as to protect the bottom of the syringe during disassembly and installation.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the highly reliable and easy-to-install large circular knitting machine needle cylinder adopts a new structural design, and its specific contents are as follows:

[0017] 1. The installation position of the syringe body is limited by the gap formed between the inner limit plate and the outer limit plate on the upper surface of the mounting base. During the installation process, the positioning ball at the lower end of the syringe body is engaged with the first positioning hole and the second positioning hole to achieve positioning, thereby adjusting the angle of the syringe body to avoid the problem of installation position deviation;

[0018] Further, by rotating the connecting ring to drive the upper fixing piece above it to move, the upper fixing piece can be rotated above the lower fixing piece, and the fixing of the syringe body is achieved by the extrusion between the two. In this process, the connecting ring can drive the four upper fixing pieces to move simultaneously. Compared with the traditional one-by-one operation, the installation is more convenient and fast.

[0019] Furthermore, an upper magnet is installed on the lower surface of the upper fixing piece, and a lower magnet is installed on the upper surface of the lower fixing piece. When the upper fixing piece rotates to the corresponding position of the lower fixing piece, the fixing is achieved by the magnetic adsorption between the upper magnet and the lower magnet, improving the firmness of the installation.

[0020] 2. A protective pad is provided on the outer surfaces of the inner limiting plate and the outer limiting plate. The soft protective pad can provide a certain buffering and protective effect, and can also reduce the friction during the installation of the syringe body, thereby achieving the purpose of protecting the syringe body.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Embodiment 1: Please refer to Figure 1 - Figure 2 , in order to solve the problem of angular deviation during the installation of the traditional syringe barrel, the following technical solutions are provided. By setting a positioning mechanism to position the syringe barrel body 1 during installation, specifically disclosed are: a circular knitting machine syringe barrel body 1 with a cylindrical structure, the syringe barrel body 1 is installed above the installation base 2, an inner limiting plate 3 and an outer limiting plate 4 are fixedly installed on the upper surface of the installation base 2, and the inner limiting plate 3 is set as an annular structure, the outer limiting plate 4 is set as a sheet-like structure inside at equal intervals. A positioning mechanism for positioning the syringe barrel body 1 is arranged between the inner limiting plate 3 and the outer limiting plate 4. The positioning mechanism includes a first positioning hole 11 opened on the inner limiting plate 3 and a second positioning hole 12 opened on the outer limiting plate 4. The positions of the first positioning hole 11 and the second positioning hole 12 correspond to each other inside and outside, and a positioning ball 10 is fixedly installed at the lower end of the syringe barrel body 1, and the positioning ball 10 is snap-fitted with both the first positioning hole 11 and the second positioning hole 12. The positioning ball 10 is made of rubber material.

[0031] When installing the syringe barrel body 1, first place the bottom of the syringe barrel body 1 into the gap formed between the inner limiting plate 3 and the outer limiting plate 4, and use the inner limiting plate 3 and the outer limiting plate 4 to initially limit the syringe barrel body 1. Then rotate the syringe barrel body 1 so that the positioning ball 10 at the lower end of the syringe barrel body 1 rotates accordingly. When the positioning ball 10 rotates to the positions of the first positioning hole 11 and the second positioning hole 12, the positioning ball 10 is squeezed into the first positioning hole 11 and the second positioning hole 12 to form a snap-fitting structure, and the position of the syringe barrel body 1 is repositioned to ensure that its installation has no deviation.

[0032] Embodiment 2: Please refer to Figure 3 - Figure 5 , in order to solve the problem that the traditional syringe barrel installation process is cumbersome due to the need to operate multiple bolts, the following technical solutions are provided. Specifically disclosed are: four lower fixing pieces 5 are fixedly installed at equal intervals on the outer surface of the lower end of the syringe barrel body 1, and the positions between the lower fixing pieces 5 and the upper fixing pieces 6 correspond to each other for quick installation. The upper fixing pieces 6 are fixedly installed with a connecting ring 7, and the connecting ring 7 and a sliding groove 201 opened on the outer surface of the installation base 2 form a sliding structure. An upper magnet 8 is fixedly installed on the lower surface of the upper fixing piece 6, and a lower magnet 9 is fixedly installed on the upper surface of the lower fixing piece 5. The magnetic poles of the upper magnet 8 and the lower magnet 9 are opposite and adsorb and fix each other.

[0033] After the positioning of the syringe body 1 is completed, rotate the connecting ring 7 on the outside of the mounting base 2 (the connecting ring 7 slides correspondingly in the sliding groove 201 formed on the outer surface of the mounting base 2), and drive the upper fixing piece 6 to move by means of the connecting ring 7. When the upper fixing piece 6 moves to a position corresponding to the lower fixing piece 5, fix the two by means of the magnetic adsorption between the upper magnet 8 and the lower magnet 9. At this time, fix the syringe body 1 by the extrusion between the upper fixing piece 6 and the lower fixing piece 5 to complete the installation. During this process, the connecting ring 7 drives multiple upper fixing pieces 6 to move synchronously, making the installation more convenient and fast.

[0034] Embodiment 3: Please refer to Figure 6 - Figure 7 , in order to solve the problem that the severe friction at the bottom during multiple installations and removals of the traditional syringe seriously affects its service life, the following technical solutions are provided, specifically disclosed: Protective pads 13 are fixedly adhered to the outer surfaces of the inner limiting plate 3 and the outer limiting plate 4, and the protective pads 13 are made of soft silicone material.

[0035] When installing the syringe body 1, the lower end of the syringe body 1 first contacts the protective pads 13 on the outer surfaces of the inner limiting plate 3 and the outer limiting plate 4, and the protective pads 13 are used to provide buffering and protection, reducing the wear of the syringe body 1 during multiple removals and installations and extending its service life.
