All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

Referring to fig. 1-4, the present invention provides a technical solution: a textile machine capable of quickly replacing needles comprises a machine body 1, wherein a driving rod 2 is installed inside the machine body 1, the bottom of the driving rod 2 is connected with a needle 4 through a positioning mechanism 3, the needle 4 comprises an extension rod 5, a slide rod 7, a supporting plate 8, a locking nut 9, a first push plate 10, a second push plate 11, an eccentric block 12, a locking screw 13, a third push plate 16 and an extrusion block 18, the extension rod 5 is installed below the outer side wall of the driving rod 2 through a bolt, the supporting plate 8 is installed at the bottom of the extension rod 5 through a bolt, the third push plate 16 and the second push plate 11 are connected to the front surface of the supporting plate 8 in a sliding mode, the extrusion block 18 is installed on opposite surfaces of the third push plate 16 and the second push plate 11 through bolts, the slide rod 7 is further installed at the end of the third push plate 16 through a bolt, the slide rod 7 is connected with the second push plate 11 in a sliding mode, and the first push plate 10 is installed at one end, far away from the third push plate 16, through a bolt, an eccentric block 12 is rotatably connected between the first push plate 10 and the second push plate 11 through a locking screw 13, and a locking nut 9 is arranged on the front surface of the eccentric block 12.

In this embodiment, when the textile machine needs to be used, the cloth can be placed below the needle 4, and the needle 4 can sew the cloth through the driving rod 2 under the cooperation of the positioning mechanism 3.

In this embodiment, when syringe needle 4 needs to be installed, can make syringe needle 4 hug closely the actuating lever 2 bottom from between two extrusion pieces 18, make push pedal one 10 and push rod two move to opposite direction along slide bar 7 lateral wall through rotatory eccentric block 12, extrusion piece 18 that the in-process that removes can make push pedal two 11 and push pedal three 16 installation extrude syringe needle 4, then the staff twists lock nut 9 again, because extrusion piece 18 fully wraps up syringe needle 4, can avoid syringe needle 4 to take place cracked phenomenon when using like this, and when needing to change syringe needle 4, make lock nut 9 antiport, then rotate eccentric block 12 and make syringe needle 4 break away from extrusion piece 18, can make things convenient for the staff to change syringe needle 4 through this.

Specifically, the outer side wall of the sliding rod 7 is provided with a spring frame 6, and the spring frame 6 is positioned between the second push plate 11 and the third push plate 16.

In this embodiment, when the needle 4 needs to be separated from the pressing block 18, the spring force of the spring frame 6 can facilitate the relative sliding between the second pushing plate 11 and the third pushing plate 16.

Specifically, the opposite surfaces of the two extrusion blocks 18 are provided with anti-slip rings 17.

In this embodiment, the anti-slip rings 17 are disposed on the opposite surfaces of the two squeezing blocks 18, and the friction force between the squeezing blocks 18 and the needle 4 can be increased by the anti-slip rings 17, so as to prevent the squeezing blocks 18 and the needle 4 from sliding.

Specifically, the sides of the second push plate 11 and the first push plate 10 facing the eccentric block 12 are smooth structures.

In this embodiment, the sides of the second push plate 11 and the first push plate 10 facing the eccentric block 12 are made to be smooth structures, so that the eccentric block 12 slides on the surfaces of the second push plate 11 and the first push plate 10 more smoothly.

Specifically, the bottom of the driving rod 2 is provided with a positioning hole 15, and magnetic powder is sprayed on the groove wall of the positioning hole 15.

In this embodiment, when the top of the needle 4 is inserted into the positioning hole 15, the top of the needle is tightly attached to the bottom of the driving rod 2 under the action of the magnetic powder, so that the needle 4 is prevented from falling.

Specifically, the grooves formed on the third pushing plate 16 and the second pushing plate 11 are connected with the protruding block 14 on the front surface of the supporting plate 8 in a sliding manner.

In this embodiment, the grooves formed in the third push plate 16 and the second push plate 11 are slidably connected with the protruding block 14, so that the third push plate 16 and the second push plate 11 can be more stable in the moving process.

Specifically, the distance between the second push plate 11 and the support plate 8 is one centimeter.

In this embodiment, the distance between the second pushing plate 11 and the supporting plate 8 is one centimeter, so that the second pushing plate 11 can be prevented from rubbing against the supporting plate 8 in the sliding process.

The working principle and the using process of the utility model are as follows: after the needle head 4 is installed, when the needle head 4 needs to be installed, the top of the needle head 4 can be tightly attached to the bottom of the driving rod 2 from between the two extrusion blocks 18, then the eccentric block 12 is rotated clockwise, the push plate I10 and the push rod II move along the outer side wall of the sliding rod 7 in opposite directions through the rotating eccentric block 12, the extrusion blocks 18 installed on the push plate II 11 and the push plate III 16 can extrude the needle head 4 in the moving process, then a worker twists the locking nut 9 to fix the eccentric block 12, and the needle head 4 is fully wrapped by the extrusion blocks 18, so that the phenomenon that the needle head 4 is broken in use can be avoided, when the needle head 4 needs to be replaced, the locking nut 9 rotates reversely, then the eccentric block 12 is rotated to enable the needle head 4 to be separated from the extrusion blocks 18, and therefore, the needle head 4 can be conveniently replaced by the worker.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
