[0002] A knitting flat knitting machine is the most common machine in the knitting field. It generally includes a knitting cam holder, a needle bed assembly, a transmission system, a roller winding mechanism, etc. Among them, the needle bed assembly is a key component of the knitting flat knitting machine. The entire knitting process is completed by the up and down movement of the knitting needles on the needle bed. Traditional knitting flat knitting machines have two front and rear needle beds, and a group of needle grooves with relatively high positional accuracy requirements for placing knitting needles are milled on the needle bed.

[0003] A knitting flat knitting machine needle bed adjusting device disclosed in Chinese Utility Model Patent Application No. 202221991149.7. By pulling the pull rod, then rotating the receiving block on the bottom surface of the upper yarn feeding controller along the opening inside the positioning block on the top of the clamping plate, and then loosening the pull rod, the linkage plate is subjected to the elastic force of the positioning spring, so that the clamping block on one side of the linkage plate is engaged with the corresponding opening on the surface of the receiving block, so that the upper yarn feeding controller is fixed after rotating a certain angle on the top of the clamping plate, to adjust the appropriate angle of the upper yarn feeding controller, which is convenient for the use of the knitting flat knitting machine needle bed.

[0004] However, when the above patent is used, due to the narrow space between the upper yarn feeding controller and the clamping plate, it is inconvenient for the staff to reach into the space between the upper yarn feeding controller and the clamping plate to pull the pull rod to move. In addition, since the pull rod, spring, clamping block and linkage plate are distributed on the left and right sides of the receiving block, it is inconvenient for a single staff member to adjust the angle of the upper yarn feeding controller while pulling the pull rod with both hands, and two people are required to cooperate in the adjustment at the same time, which makes the angle adjustment of the upper yarn feeding controller very troublesome. Therefore, a knitting flat knitting machine needle bed adjusting device needs to be designed. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a knitting flat knitting machine needle bed adjusting device.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a knitting flat knitting machine needle bed adjusting device, including a clamping plate and an upper yarn feeding controller. The upper end of the clamping plate is fixedly connected with a bearing cylinder and a fixing frame. A plurality of fixing shells are fixedly connected inside the fixing frame, and the plurality of fixing shells are evenly distributed around the bearing cylinder. The bottom end of the upper yarn feeding controller is fixedly connected with a cylindrical rotating seat, and the cylindrical rotating seat is located inside the bearing cylinder and is rotatably connected with the bearing cylinder. A rotating disk is fixedly connected to the circumferential surface of the cylindrical rotating seat. A plurality of inserting shells are connected inside the rotating disk through inserting parts. The inserting shells are located above the fixing shells, and the inserting shells are slidably and cooperatively connected with the fixing shells.

[0007] Further, mounting holes are formed in the lower end surface of the card board.

[0008] Further, the plug-in member includes a handle, a bearing seat, a rotating shaft, a first bevel gear, a second bevel gear, a first gear, a second gear, a first threaded rod, a second threaded rod and a bearing bracket. A bearing seat and a bearing bracket are fixedly connected to the upper end of the rotating disc. A rotating shaft is rotatably connected inside the bearing seat. A handle and a first bevel gear are fixedly connected to both ends of the rotating shaft respectively. A second threaded rod and two first threaded rods are rotatably connected inside the bearing bracket. The two first threaded rods are respectively located at the left and right ends of the second threaded rod. The circumferential surfaces of the second threaded rod and the two first threaded rods are all threadedly connected with plug shells. A plurality of plug shells all penetrate downward through the rotating disc and are slidably connected with the rotating disc. A second gear is fixedly connected to the circumferential surface of the second threaded rod. The circumferential surfaces of the two first threaded rods are all fixedly connected with first gears. The two first gears are both meshed with the second gear. The two first gears and the second gear are all located above the bearing bracket.

[0009] Further, the thread shapes on the surfaces of the two first threaded rods are the same, and the thread directions on the surfaces of the first threaded rod and the second threaded rod are opposite.

[0010] Further, a notch is formed in the front end surface of the fixed shell, and the notch communicates with the fixed shell.

[0011] Further, a plurality of convex shafts are fixedly connected to the circumferential surface of the rotating disc.

[0012] The utility model has the following beneficial effects:

[0013] Compared with the prior art, for this knitting flat knitting machine needle bed adjusting device, through the mutual cooperation of the plug-in member, the plug shell, the rotating shaft, the bearing cylinder and the fixed shell, it is convenient to adjust the angle of the upper yarn feeding controller, so as to facilitate the cooperation with the knitting flat knitting machine needle bed. In this process, only one staff member needs to manually control the operation of the plug-in member. After the plurality of plug shells are lifted up and completely separated from the fixed shell, the staff member can manually push the upper yarn feeding controller to rotate around the bearing cylinder, so as to play the role of angle adjustment. Until the upper yarn feeding controller rotates to a suitable angle, manually control the operation of the plug-in member again, and make the plug shell move down and insert into the fixed shell, then the fixing of the upper yarn feeding controller can be completed. Since only one staff member is required to operate throughout the process, it saves more manpower. And because the handle in the plug-in member is located at the outer end of the upper yarn feeding controller and is not between the upper yarn feeding controller and the card board, it is more convenient for the staff member to operate.

The bottom end of the upper yarn feeding controller 3 is fixedly connected with a cylindrical rotating seat 19, and the cylindrical rotating seat 19 is located inside the bearing cylinder 20 and is rotatably connected with the bearing cylinder 20. The circumferential surface of the cylindrical rotating seat 19 is fixedly connected with a rotating disk 5. A plurality of insert shells 12 are connected inside the rotating disk 5 through plug-in members. The insert shells 12 are located above the fixed housings 7, and the insert shells 12 are slidably and cooperatively connected with the fixed housings 7. During operation, the present utility model is more convenient for adjusting the angle of the upper yarn feeding controller 3, so as to be convenient for cooperating with the needle bed of the knitting flat knitting machine.

[0022] Furthermore, mounting holes 2 are formed on the lower end surface of the clamping plate 1. During operation, under the action of the mounting holes 2, it is convenient to fixedly connect the clamping plate 1 with the support frame of the needle bed of the knitting flat knitting machine.

[0023] Furthermore, the connector includes a handle 15, a bearing seat 16, a rotating shaft 17, a first bevel gear 10, a second bevel gear 11, a first gear 8, a second gear 9, a first threaded rod 14, a second threaded rod 13, and a bearing bracket 6. The upper end of the rotating disc 5 is fixedly connected with the bearing seat 16 and the bearing bracket 6. The inside of the bearing seat 16 is rotatably connected with the rotating shaft 17. The two ends of the rotating shaft 17 are respectively fixedly connected with the handle 15 and the first bevel gear 10. The inside of the bearing bracket 6 is rotatably connected with the second threaded rod 13 and two first threaded rods 14. The two first threaded rods 14 are respectively located at the left and right ends of the second threaded rod 13. The circumferential surfaces of the second threaded rod 13 and the two first threaded rods 14 are all threadedly connected with the plug housing 12. A plurality of plug housings 12 all penetrate downward through the rotating disc 5 and are slidably connected with the rotating disc 5. The circumferential surface of the second threaded rod 13 is fixedly connected with the second gear 9. The circumferential surfaces of the two first threaded rods 14 are all fixedly connected with the first gear 8. The two first gears 8 are both meshed with the second gear 9. The two first gears 8 and the second gear 9 are all located above the bearing bracket 6. The thread shapes on the surfaces of the two first threaded rods 14 are the same, and the thread directions on the surfaces of the first threaded rod 14 and the second threaded rod 13 are opposite. During operation, rotating the handle 15 drives the rotating shaft 17 to rotate, and then drives the first bevel gear 10 to rotate. The first bevel gear 10 drives the second bevel gear 11 to rotate, thereby driving the second threaded rod 13 to rotate. Under the action of the second threaded rod 13, the second gear 9 is driven to rotate, and at the same time, the two first gears 8 are driven to rotate. At this time, the two first threaded rods 14 and the second threaded rod 13 will rotate simultaneously. Under the action of the first threaded rod 14 and the second threaded rod 13, a plurality of plug housings 12 can be adjusted up and down along the rotating disc 5, so that the plug housings 12 are gradually inserted into the fixed housing 7 or gradually separated from the fixed housing 7. After the plug housing 12 is separated from the fixed housing 7, it is convenient to adjust the angle of the upper yarn feeding controller 3. After the plug housing 12 is inserted into the fixed housing 7, the upper yarn feeding controller 3 can be fixed so that it can be stably in this position.

[0024] Furthermore, a notch is formed on the front end face of the fixed housing 7, and the notch communicates with the fixed housing 7. During operation, the existence of the notch facilitates the staff to clearly observe the depth of the plug housing 12 inserted into the fixed housing 7.

[0025] Furthermore, a plurality of convex shafts 18 are fixedly connected to the circumferential surface of the rotating disc 5. During operation, the existence of the convex shafts 18 facilitates the staff to control the rotation of the rotating disc 5, thereby driving the rotation of the rotating shaft 17 and the upper yarn feeding controller 3.

[0026] Working principle:

[0027] In use, under the action of the mounting hole 2, the clamping plate 1 is fixedly connected to the support frame of the knitting flatbed knitting machine needle bed. At this time, the upper yarn feeding controller 3 is connected to the knitting flatbed knitting machine needle bed. When the angle of the upper yarn feeding controller 3 needs to be adjusted, rotate the handle 15 to drive the rotating shaft 17 to rotate. Since the handle 15 is located at the outer end of the upper yarn feeding controller 3, it is more convenient for the staff to operate. The rotation of the rotating shaft 17 drives the first bevel gear 10 to rotate, and the first bevel gear 10 drives the second bevel gear 11 to rotate, thereby driving the second threaded rod 13 to rotate. Under the action of the second threaded rod 13, the second gear 9 is driven to rotate, and at the same time, the two first gears 8 are driven to rotate. At this time, the two first threaded rods 14 and the second threaded rod 13 will rotate simultaneously. Under the action of the first threaded rod 14 and the second threaded rod 13, multiple plug housings 12 can be moved upward along the rotating disc 5, so that the plug housings 12 are gradually separated from the fixed housing 7. Until the plug housings 12 are completely separated from the fixed housing 7, the staff can directly push the upper yarn feeding controller 3 to rotate or push the rotating disc 5 to rotate around the bearing cylinder 20. In this way, the angle adjustment of the upper yarn feeding controller 3 is completed. After the adjustment is completed, control the plug-in component again to insert the plug housing 12 into the corresponding fixed housing 7. At this time, the fixation of the upper yarn feeding controller 3 can be completed, so as to facilitate the cooperation with the knitting flatbed knitting machine needle bed.
