Description

Technical Field

[0001] The utility model relates to the technical field of doffing frames for spinning frames, and specifically relates to a doffing frame device for a spinning frame. Background Art

[0002] A spinning frame is a spinning machine that drafts, twists, and winds semi-finished roving or sliver into fine yarn bobbin yarns during the spinning process. The sliver is drafted and twisted into roving on a roving frame, the comber combs the fibers into combed sliver, the gill box combines the sliver, and the needle bar drafts to improve the sliver structure. The roving is further twisted into fine yarn on a ring spinning frame. The spinning frame is the main machine for spinning.

[0003] For example, the patent with the publication number CN220485936U discloses a doffing frame device for a spinning frame, which includes: a bottom frame for bearing and limiting, a yarn bobbin support plate fittingly arranged inside the bottom frame, and a limiting rod fittingly penetrating through the inner side of the left end of the yarn bobbin support plate; it also includes: symmetric moving wheels fixedly installed by screws on the lower surface of the outer end of the bottom frame, and a controller embedded and installed inside the upper right rear end of the bottom frame; yarn bobbin bearing trays are fixedly installed at equal intervals on the upper surface of the yarn bobbin support plate, and yarn bobbin lining columns are connected to the yarn bobbin bearing trays; the lower end of the limiting rod is fixedly connected to the bottom frame, and an adjusting rod is arranged above the right end of the bottom frame.

[0004] Through the above settings, the doffing frame device for a spinning frame in the prior art is convenient for adjusting the height of the yarn bobbin bearing tray, so that the yarn bobbins outside the yarn bobbin lining columns are suitable for different spinning frames for doffing, convenient for quickly taking and placing the yarn bobbins outside the yarn bobbin lining columns, and convenient for dust collection and cleaning, making the yarn highly clean. However, the doffing frame device for a spinning frame in the prior art solution has the following defects during operation:

[0005] In the above device, the height of the yarn bobbin support plate is adjusted by driving the adjusting rod to rotate by a motor, so that the yarn bobbins can be adjusted to a suitable height for work, and then the yarn bobbins are quickly taken and placed by the cylinder working. This device uses two different power components to achieve two different effects, resulting in a single working effect of the device and increasing the manufacturing cost of the device. Content of the Utility Model

[0006] The utility model aims to provide a doffing frame device for a spinning frame, which is mainly used to solve the technical problems of single working effect and relatively high manufacturing cost existing in the prior art.

[0007] To solve the above technical problems, the utility model provides the following technical solutions:

[0008] A doffing frame device for a spinning frame, comprising a base frame. A limiting rod is fixedly connected to the lower side wall of the base frame. A lifting plate is slidably connected to the inner side wall of the base frame. A plurality of yarn bobbin supporting trays are fixedly connected to the top of the lifting plate, and the limiting rod penetrates through the lifting plate. A bearing plate is lapped on the top of the lifting plate, and the yarn bobbin supporting trays penetrate through the bearing plate. Connecting blocks are fixedly connected to both ends of the side wall of the bearing plate. A lifting assembly is threadedly connected to the inner side wall of the connecting block. A motor is fixedly connected to the lower side wall of the base frame. A rotating shaft is fixedly connected to the output end of the motor. A lead screw sleeve is sleeved on the outer side wall of the rotating shaft, and the lead screw sleeve is threadedly connected to the lifting plate. A turntable is fixedly connected to the bottom of the outer side wall of the lead screw sleeve. An installation groove is formed inside the turntable, and an adjusting assembly is slidably connected inside the installation groove.

[0009] The working principle and beneficial effects of the present utility model:

[0010] 1. Working principle: When this device is in use, first place this device at a suitable position at the spinning frame. When it is necessary to adjust the height of the yarn bobbin, only need to start the motor. The motor drives the rotating shaft to rotate. During the rotation of the rotating shaft, the lead screw sleeve is driven to rotate, and then the lifting plate slides upward along the inner side wall of the base frame, so as to achieve the purpose of adjusting the height of the yarn bobbin. When it is necessary to remove the yarn bobbin, only need to adjust the adjusting assembly so that the rotating shaft and the lead screw sleeve are not in contact. Then, during the rotation of the rotating shaft, the inner side wall of the rotating shaft and the lead screw sleeve rotates, and the lifting plate will not rise or fall. As the rotating shaft rotates, the lifting assembly is driven to work by the rotating shaft. The bearing plate is driven to move upward by the lifting assembly. During the upward movement of the lifting plate, the yarn bobbin is driven to move upward, so as to quickly complete the work of taking and placing the yarn bobbin.

[0011] 2. Beneficial effects:

[0012] The prior art solves the technical problem of quickly taking and placing the yarn bobbin by setting a cylinder. However, the prior art has the technical problems of single working effect and high manufacturing cost. This solution can quickly take and place the sleeve through the set lifting assembly. The set adjusting assembly enables the click to control the rotation of the lead screw sleeve during rotation, thereby solving the technical problem of lifting the lifting plate or taking and placing the yarn bobbin.

[0013] Preferably, the lifting assembly includes a screw rod threadedly connected to the inner side wall of the connecting block. The bottom of the screw rod is rotatably connected to the lower side wall of the chassis. The top of the screw rod is fixedly connected to a driven gear. The top of the rotating shaft is fixedly connected to a driving gear, and the driving gear meshes with the driven gear. When it is necessary to pick up or place the yarn bobbin, only need to start the motor, drive the rotating shaft to rotate by the motor, make the rotating shaft rotate along the inner side wall of the lead screw sleeve. During the rotation of the rotating shaft, drive the driving gear to rotate, and then drive the driven gear to rotate through the driving gear. When the driven gear rotates, drive the screw rod to rotate, and then drive the bearing plate to move upward through the connecting block. Finally, quickly remove the yarn bobbin on the outer side wall of the yarn bobbin bearing tray through the bearing plate.

[0014] Preferably, the adjusting assembly includes a limiting block slidably connected to the inner side wall of the installation groove. One end of the limiting block close to the installation groove is fixedly connected to an electromagnet. The inner side wall of the installation groove is fixedly connected to an iron block. A limiting groove is opened on the outer side wall of the rotating shaft at the position of the limiting block. When it is necessary to adjust the height of the yarn bobbin, only need to turn off the electromagnet, then the iron block will not be adsorbed by the electromagnet, and then snap the limiting block into the inside of the limiting groove. During the rotation of the rotating shaft, drive the lead screw sleeve to rotate through the limiting block, so that the lead screw sleeve and the screw rod rotate at the same time. Then the lifting plate and the bearing plate move upward at the same time under the action of the lead screw sleeve and the screw rod respectively, so as to achieve the purpose of quickly raising the yarn bobbin.

[0015] Preferably, a spring is fixedly connected to the side wall of the installation groove, and the other end of the spring is fixedly connected to the side wall of the electromagnet. When the electromagnet is turned off, the end of the limiting block abuts against the outer side wall of the rotating shaft under the action of the compressed spring. As the rotating shaft rotates, when the limiting block coincides with the limiting groove, the limiting block automatically snaps into the inside of the limiting groove under the action of the compressed spring, so as to achieve the purpose of quick clamping.

[0016] Preferably, a mounting seat is fixedly connected to the side wall of the chassis at the position of the turntable, and the turntable is rotatably connected to the inner side wall of the mounting seat. When the rotating shaft drives the lead screw sleeve to rotate through the limiting block, the turntable rotates with the mounting seat, thereby increasing the stability of the device.

[0017] Preferably, the pitch of the lead screw sleeve is equal to the pitch of the screw rod, so that the lifting speeds of the lifting plate and the bearing plate are the same during the simultaneous rotation of the lead screw sleeve and the screw rod. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Such as Figures 1-5As shown in the figure, a doffing frame device for a spinning frame includes a chassis 1. A limiting rod 4 is fixedly connected to the lower side wall of the chassis 1. A lifting plate 3 is slidably connected to the inner side wall of the chassis 1. A plurality of bobbin supporting trays 5 are fixedly connected to the top of the lifting plate 3. And the limiting rod 4 penetrates through the lifting plate 3. A bearing plate 2 is lapped on the top of the lifting plate 3. And the bobbin supporting trays 5 penetrate through the bearing plate 2. Connecting blocks 10 are fixedly connected to both ends of the side wall of the bearing plate 2. A lifting assembly is threadedly connected to the inner side wall of the connecting block 10. The lifting assembly includes a screw rod 9 threadedly connected to the inner side wall of the connecting block 10. The bottom of the screw rod 9 is rotatably connected to the lower side wall of the chassis 1. A driven gear 8 is fixedly connected to the top of the screw rod 9. A driving gear 7 is fixedly connected to the top of a rotating shaft 12. And the driving gear 7 meshes with the driven gear 8. When the rotating shaft 12 rotates, it drives the driving gear 7 to rotate. Then, the driven gear 8 is driven to rotate by the driving gear 7. When the driven gear 8 rotates, it drives the screw rod 9 to rotate. The bearing plate 2 is driven to move upward through the connecting block 10. Finally, the bobbins on the outer side wall of the bobbin supporting trays 5 are quickly removed through the bearing plate 2. A motor 11 is fixedly connected to the lower side wall of the chassis 1. The output end of the motor 11 is fixedly connected to a rotating shaft 12. A lead screw sleeve 6 is sleeved on the outer side wall of the rotating shaft 12. And the lead screw sleeve 6 is threadedly connected to the lifting plate 3. A turntable 13 is fixedly connected to the bottom of the outer side wall of the lead screw sleeve 6. An installation groove 16 is formed inside the turntable 13. An adjusting assembly is slidably connected inside the installation groove 16. The adjusting assembly includes a limiting block 20 slidably connected to the inner side wall of the installation groove 16. An electromagnet 19 is fixedly connected to one end of the limiting block 20 close to the installation groove 16. An iron block 18 is fixedly connected to the inner side wall of the installation groove 16. A limiting groove 15 is formed in the outer side wall of the rotating shaft 12 at the position of the limiting block 20. A spring 17 is fixedly connected to the side wall of the installation groove 16. The other end of the spring 17 is fixedly connected to the side wall of the electromagnet 19. When the height of the bobbin needs to be adjusted, only need to start the motor 11, use the motor 11 to drive the rotating shaft 12 to rotate, and then turn off the electromagnet 19. Then the iron block 18 will not be adsorbed to the electromagnet 19. Then, under the action of the compressed spring 17, the end of the limiting block 20 abuts against the outer side wall of the rotating shaft 12. As the rotating shaft 12 rotates, when the limiting block 20 coincides with the limiting groove 15, the limiting block 20 automatically snaps into the limiting groove 15 under the action of the compressed spring 17. Then, when the rotating shaft 12 rotates, the lead screw sleeve 6 is driven to rotate through the limiting block 20. Then the lifting plate 3 and the bearing plate 2 move upward simultaneously under the action of the lead screw sleeve 6 and the screw rod 9 respectively, so as to achieve the purpose of quickly raising the bobbin.

[0026] As can be seen from the above, the specific implementation manner of the present utility model is as follows:

[0027] When this device is in use, first place the device at a suitable position near the flyer frame. When it is necessary to adjust the height of the yarn bobbin, only need to start the motor 11. The motor 11 drives the rotation of the rotating shaft 12. Then turn off the electromagnet 19, and the iron block 18 will no longer be adsorbed by the electromagnet 19. Under the action of the compression spring 17, the end of the limit block 20 will be in contact with the outer side wall of the rotating shaft 12. As the rotating shaft 12 rotates, when the limit block 20 coincides with the limit groove 15, under the action of the compression spring 17, the limit block 20 automatically snaps into the inside of the limit groove 15. During the rotation of the rotating shaft 12, the lead screw sleeve 6 is driven by the limit block 20. While the rotating shaft 12 rotates, the driving gear 7 is driven to rotate. Then, the driven gear 8 is driven to rotate through the driving gear 7. When the driven gear 8 rotates, the screw rod 9 is driven to rotate. Then, the lifting plate 3 and the bearing plate 2 move upward simultaneously under the action of the lead screw sleeve 6 and the screw rod 9 respectively, so as to achieve the purpose of quickly raising the yarn bobbin. When it is necessary to pick up and place the yarn bobbin, turn on the electromagnet 19 to make the iron block 18 engage with the electromagnet 19 again. Then the limit block 20 will disengage from the limit groove 15, and the rotating shaft 12 will rotate along the inner side wall of the lead screw sleeve 6. At this time, the rotation of the motor 11 will only drive the rotation of the screw rod 9, and the bearing plate 2 is driven to move upward through the connecting block 10. Finally, the yarn bobbin on the outer side wall of the yarn bobbin supporting tray 5 is quickly removed through the bearing plate 2.
