Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment technology, specifically to a protective device for a large circular knitting machine. Background Technology

[0002] Circular knitting machines, also known as circular weft knitting machines, have seen rapid development due to their numerous loop-forming systems (commonly referred to as yarn feed paths or loop-forming paths, or simply paths), high speeds, high outputs, rapid pattern changes, good fabric quality, fewer processes, and strong product adaptability. Currently, most circular knitting machines have protective nets between adjacent legs. However, these nets are typically fixed directly to the legs with bolts. When the bolts loosen, the nets easily fall off. Furthermore, the fixed position of the nets makes it impossible to change their location as needed. Utility Model Content

[0003] The present invention provides a protective device for a large circular knitting machine to solve the above-mentioned technical problems. The device eliminates bolt connections and adopts a connection structure that is directly sleeved on the connecting shaft, which avoids the problem of bolt loosening, and the position of the protective net can be adjusted.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model for a protective device for a textile circular knitting machine is as follows:

[0005] The device includes a large circular knitting machine main unit, with multiple legs connected to its lower part. Each pair of adjacent legs is connected to a protective mechanism, which includes two protective plates rotatably connected to the two legs. One of the protective plates is slidably connected to the other. Each leg has multiple vertically arranged adjustment grooves. Each adjustment groove has a sliding seat slidably connected to it. Each sliding seat has a vertically upward connecting shaft connected to it. The protective plates have bushings corresponding to the connecting shafts connected to their sides. The protective plates are rotatably connected to the legs by the bushings fitted onto the connecting shafts.

[0006] Each of the foot posts is provided with two adjustment grooves; each of the two adjustment grooves is slidably connected to a slide block; each of the two slide blocks is connected to a vertically upward connecting shaft; the side of the protective plate is connected to two bushings that correspond to the two connecting shafts respectively; the protective plate is rotatably connected to the foot post by being fitted onto the two connecting shafts by the two bushings respectively.

[0007] The protective plate is connected to a mounting panel; the connecting shaft is connected to the mounting panel.

[0008] Locking seats are connected to both the upper and lower sides of the slide; locking bolts are threaded onto each locking seat; the bottom end of each locking bolt passes through the locking seat and abuts against the foot post.

[0009] Of the two protective plates, one protective plate is connected to slide rails on both the top and bottom sides, while the other protective plate is slidably connected between the two slide rails.

[0010] The main body of the large circular knitting machine is connected to three legs.

[0011] The technical effects that this utility model can achieve are:

[0012] 1. This utility model abandons the existing bolt connection and adopts a connection structure that is directly sleeved on the connecting shaft. This connection structure is not only easy to disassemble and install, but also avoids the problem of loosening of existing bolts.

[0013] 2. The connecting shaft of this utility model is installed on the slide block, and the slide block is slidably connected to the adjusting slide groove. Therefore, the front and rear positions of the device on the foot post can be changed by the slide block, that is, the front and rear positions of the protective mechanism on the foot post can be adjusted.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] See Figures 1 to 6 .

[0023] A protective device for a circular knitting machine includes a main body 1, with multiple support columns 2 connected to the bottom of the main body 1, and a protective mechanism connected between each adjacent pair of support columns 2. Specifically, three support columns 2 are connected to the bottom of the main body 1. The protective mechanism includes two protective plates 3 rotatably connected to the two support columns 2 respectively. One of the two protective plates 3 is slidably connected to the other protective plate 3. Specifically, one of the two protective plates 3 has slide rails 21 connected to both its upper and lower sides, and the other protective plate 3 is slidably connected between the two slide rails 21 (see reference). Figure 1 , 6 Therefore, the total length of the protective mechanism can be changed by sliding the protective plate 3 on another protective plate 3.

[0024] Each foot post 2 has multiple vertically arranged adjustment grooves 4, each adjustment groove 4 is slidably connected to a slide seat 5, and each slide seat 5 is connected to a vertically upward connecting shaft 6. The side of the protective plate 3 is connected to a bushing 7 corresponding to the connecting shaft 6. The protective plate 3 is rotatably connected to the foot post 2 by fitting the bushing 7 onto the connecting shaft 6. Specifically, each foot post 2 has two adjustment grooves 4, each adjustment groove 4 is slidably connected to a slide seat 5, and each slide seat 5 is connected to a vertically upward connecting shaft 6. The side of the protective plate 3 is connected to two bushings 7 corresponding to the two connecting shafts 6 respectively. The protective plate 3 is rotatably connected to the foot post 2 by fitting the two bushings 7 onto the two connecting shafts 6 respectively. More specifically, the protective plate 3 is connected to a mounting panel 11, and the connecting shaft 6 is connected to the mounting panel 11.

[0025] As a preferred embodiment, locking seats 12 are connected to both the upper and lower sides of the slide 5, and locking bolts 13 are threaded onto the locking seats 12. The bottom end of the locking bolts 13 passes through the locking seats 12 and abuts against the foot column 2.

[0026] In use, the slide block 5 is first slidably connected to the adjusting groove 4 of the foot post 2, so the slide block 5 can slide along the adjusting groove 4 to change its position. After adjusting the position, the locking bolt 13 is tightened. The bottom end of the locking bolt 13 passes through the locking seat 12 and abuts against the foot post 2. The friction between the locking bolt 13 and the foot post 2 limits the position of the slide block 5. The protective plate 3 is connected to the foot post 2 by sleeve 7 on the connecting shaft 6 of the corresponding slide block 5. This connection method of the protective plate 3 does not require bolts, which makes it easy to install and disassemble, and avoids the problem that the protective net 3 is easy to fall off after the existing bolts are loosened (the existing protective net 3 is generally directly fixed to the foot post 2 by bolts). Since the front and rear positions of the slide block 5 of this invention can be adjusted, the position of the protective mechanism can also be adjusted.
