Figure 9 As described in the embodiments of this utility model Figure 8 Enlarged view of point B in the image. Figure 10 This is a schematic diagram of the third usage state of the auxiliary tooling in the embodiments of this utility model.

[0058] like Figures 1 to 10 As shown, the auxiliary tooling for changing the syringe cylinder and needle plate of the double-sided large circular knitting machine in this embodiment includes: a support base 1, a lifting assembly 2, an auxiliary assembly 3, and a sliding plate 4.

[0059] The support base 1 is used to fix the syringe retaining ring 110 on the large circular knitting machine.

[0061] The lifting assembly 2 includes: a crank handle 21, a lifting screw 22, and a support plate 23.

[0062] The lifting screw 22 passes through the support base 1 and engages in the threaded through hole of the support base 1. The crank handle 21 and the support plate 23 are respectively located at the bottom and top of the lifting screw 22. When the crank handle 21 is rotated, it is used to drive the lifting screw 22 and the support plate 23 to rise and fall. When the support plate 23 rises, it is used to contact and abut against the needle plate support ring 210. When the support plate 23 rises and falls, it is used to drive the needle plate support ring 210 to rise and fall.

[0063] Multiple sets of auxiliary components 3 are provided, which are used to assemble and fix on the needle plate support ring 210 and are evenly distributed along the circumference of the needle plate support ring 210.

[0064] Two slide plates 4 are provided, which are used to assemble and fix the syringe retaining ring 110 in a spaced and parallel manner, and one side of the slide plate 4 extends outward from the frame of the large circular knitting machine. The slide plate 4 is used to place the syringe 100 to support the syringe and needle plate, so that the syringe and needle plate can slide outward, thereby moving the syringe and needle plate out of the frame of the large circular knitting machine.

[0065] It is not difficult to see from the above that the auxiliary tooling for changing the syringe needle plate of the double-sided large circular knitting machine in this embodiment is provided with a support base, a lifting assembly, an auxiliary assembly and a sliding plate. The support base is fixed on the syringe fixing ring. The lifting assembly includes a crank handle, a lifting screw and a support plate. The lifting screw is engaged with the threaded through hole of the support base. The crank handle and the support plate are respectively set at the bottom and top of the lifting screw. Multiple sets of auxiliary assemblies are provided and two sliding plates are provided. This embodiment describes an auxiliary fixture for replacing syringes and needle discs on a double-sided circular knitting machine. In use, the support base is installed on the syringe fixing ring. The lifting screw is raised by cranking the handle, bringing the support plate into contact with the needle disc support ring. All fixing screws on the needle disc, syringe, and needle disc support ring are removed. The lifting screw and support plate are slowly lowered by cranking the handle, first placing the needle disc at the syringe opening. Then, the lifting screw continues to lower the needle disc support ring below the highest surface of the syringe fixing ring. Multiple auxiliary components are evenly installed on the needle disc support ring. The lifting screw is then raised a certain height, and the auxiliary components lift the syringe and needle disc upwards. The sliding plate is installed on the syringe fixing ring. The lifting screw is lowered, placing the syringe and needle disc on the sliding plate. The removed syringe and needle disc are moved outwards. The new syringe and needle disc to be replaced are then placed on the sliding plate, moved to the center position, and the above steps are reversed to complete the installation and replacement of the syringe and needle disc. With the help of auxiliary tooling, the replacement process has been transformed from requiring multiple people to operate in a single person, and the replacement can be completed quickly and conveniently, reducing production downtime and improving the efficiency and safety of changing the syringe and needle plate of the double-sided circular knitting machine.

[0066] Optionally, the auxiliary tooling for changing the syringe needle plate of the double-sided circular knitting machine in this embodiment includes a support base 1 comprising: a frame support rod 11, a fixed plate 12, and a movable rod 13.

[0067] There are two frame support rods 11, which are spaced apart and parallel to each other. The fixing plate 12 is set on the frame support rod 11, and the threaded through hole of the support seat 1 is set on the fixing plate 12, that is, the lifting screw 22 passes through and engages with the fixing plate 12.

[0068] The movable rod 13 is slidably mounted on both sides of the frame support rod 11, and the movable rod 13 is assembled and fixed on the syringe fixing ring 110 by a manual screw.

[0069] Furthermore, in this embodiment, the auxiliary tooling for changing the syringe cylinder and needle plate of the double-sided large circular knitting machine, the support base 1, also includes: a spring pin 14.

[0070] The frame support rod 11 is a square tube.

[0071] One end of the movable rod 13 is provided with multiple pin holes.

[0072] One end of the movable rod 13 is slidably sleeved inside the frame support rod 11, and the other end of the movable rod 13 is connected by a connecting rod 15. A spring pin 14 is provided on the side wall of the frame support rod 11, and when the spring pin 14 is inserted into the pin hole of the movable rod 13, it fixes the movable rod 13 to the frame support rod 11.

[0073] Furthermore, in this embodiment, the auxiliary tooling for changing the syringe cylinder and needle plate of the double-sided circular knitting machine, the lifting assembly 2, also includes: a bearing 24 and a guide rod 25.

[0074] The fixing plate 12 is provided with guide holes.

[0075] The support plate 23 is mounted on the top of the lifting screw 22 via the bearing 24.

[0076] Two guide rods 25 are vertically arranged, with the top of the guide rods 25 fixedly mounted on the support plate 23, and the guide rods 25 are slidably inserted into the guide holes of the fixing plate 12.

[0077] Furthermore, in this embodiment, the auxiliary tooling for changing the syringe cylinder and needle plate of the double-sided large circular knitting machine, the lifting assembly 2, also includes: a limiting plate 26.

[0079] A limiting plate 26 is mounted on the support plate 23, and the limiting plate 26 is equipped with a positioning pin 261. When the support plate 23 rises to the top and contacts and abuts against the needle plate support ring 210, the positioning pin 261 of the limiting plate 26 inserts into the positioning hole 211 of the needle plate support ring 210, thereby positioning the needle plate support ring 210 on the support plate 23. When the needle plate support ring 210 is reinstalled and fixed on the machine frame, it can be accurately positioned on the machine frame, making installation more convenient.

[0080] Optional, such as Figure 2 and Figure 9 As shown, the auxiliary tooling for changing the syringe cylinder and needle plate of the double-sided large circular knitting machine in this embodiment includes auxiliary component 3: fixed base 31 and lifting rod 32.

[0081] The mounting bases 31 of the multiple auxiliary components 3 are used to assemble and fix them on the needle plate support ring 210, and the multiple mounting bases 31 are evenly distributed along the circumferential direction of the needle plate support ring 210.

[0082] The lifting rod 32 is mounted on the fixed base 31 and passes through the fixed through hole of the syringe fixing ring 110, abutting against the syringe 100. When the lifting screw 22 drives the support plate 23 and the needle plate support ring 210 to rise and fall, the lifting rod 32 can support the syringe 100 and drive the syringe and needle plate to rise and fall.

[0083] Optional, such as Figure 10 As shown, in this embodiment, the auxiliary tooling for changing the syringe and needle plate of the double-sided large circular knitting machine has two slide plates 4, each of which includes a short slide plate 41 and a long slide plate 42.

[0084] The short slide plate 41 is used to assemble on the inner side of the syringe fixing ring 110, and the long slide plate 42 is used to assemble on the outer side of the syringe fixing ring 110 and extends to the outer side of the large circular knitting machine frame.

[0085] In this embodiment, each slide is divided into two sections to avoid the protrusions on the top surface of the syringe retaining ring, making assembly easier.

[0086] Furthermore, in this embodiment, the auxiliary tooling for changing the syringe cylinder and needle plate of the double-sided large circular knitting machine has a support column 421 at the bottom of the long slide plate 42.

[0087] When the long slide plate 42 is set on the syringe fixing ring, the bottom end of the support column 421 abuts against the frame of the large circular knitting machine, providing support for the long slide plate 42 and preventing the long slide plate 42 from bending and deforming during the movement of the syringe needle plate.

[0088] Optional, such as Figure 7 As shown, in this embodiment, the auxiliary tooling for changing the syringe needle plate of a double-sided large circular knitting machine has a top cone shape with a smaller top and a larger bottom for the support plate 23.

[0089] The bottom end of the support plate 23 is provided with a limiting step.

[0090] When the lifting screw 22 drives the support plate 23 to rise, the top of the support plate 23 is inserted into the needle plate support ring 210 until the shoulder of the limiting step of the support plate 23 contacts and abuts against the needle plate support ring 210, and the support plate 23 provides support for the needle plate support ring 210.

[0091] Furthermore, in this embodiment, the auxiliary tooling for changing the syringe and needle plate of the double-sided large circular knitting machine has a foldable handle 21, the handle of which can be folded to reduce storage space.

[0092] The auxiliary tooling of this utility model has the following usage process:

[0093] S1 mounts the support base onto the syringe retaining ring. By cranking the handle, the lifting screw and support plate rise, causing the support plate to contact and abut against the syringe holder ring, and the positioning pin of the limiting plate to insert into the positioning hole of the syringe holder ring. Figure 6 The state shown.

[0094] After removing all the fixing screws of the needle disc, syringe, and needle disc support ring, S2 slowly lowers the lifting screw by cranking the handle. The support plate then slowly lowers the needle disc support ring and the needle disc. First, place the needle disc at the syringe nozzle, and then continue to lower the lifting screw until the needle disc support ring is below the highest surface of the syringe fixing ring.

[0095] S3 installs the mounting bases of multiple (four) auxiliary components evenly on the needle plate support ring, and the lifting rods of the auxiliary components are installed in the fixing through holes of the syringe. Then, by cranking the handle, the lifting screw is raised 10-15mm, and the lifting rods lift the syringe needle plate upwards, causing the syringe to leave the syringe fixing ring. The two sliding plates are then installed on the syringe fixing ring, and the lifting screw is lowered, placing the syringe needle plate on the sliding plates. Figure 8 and Figure 9 The state shown.

[0096] The S4 syringe tray is placed behind the slide, allowing the used syringe tray to be moved outwards and removed. Figure 10 The state shown.

[0097] Then place the new syringe and needle plate on the slide, move it to the center of the frame, and then reverse the above steps to install the new syringe onto the frame. This completes the installation and replacement of the syringe and needle plate.
