Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to a lifting device for spandex yarn rolls on a core-spun yarn machine. Background Technology

[0002] Because cotton yarn often breaks during the core-spun yarn process, spandex yarn often gets tangled on the shuttle, resulting in poor material quality and waste. The spandex yarn spool lifting device for core-spun yarn machines can solve this problem. When the lifting mechanism is powered on, the tray rises, lifting the spandex yarn spool and detaching it from the shaft so it no longer gets tangled.

[0003] Most existing spandex filament spool lifting devices for core-spun yarn machines are driven by motors and gearboxes, which have the following disadvantages:

[0004] 1. The driver board is complex and expensive;

[0005] 2. Without a travel limit mechanism, the motor continues to be powered after the lift reaches the desired height, causing severe motor overheating and a high failure rate.

[0006] 3. The motor needs to be equipped with a reduction module, otherwise insufficient driving force or excessive speed may cause the coil to fall off.

[0007] 4. The lifting and resetting process requires a drive motor to complete the reset, which results in low efficiency, complex control, and additional positioning control after the object is in place.

[0008] Therefore, there is an urgent need for a simple, stable, and efficient spandex filament spool lifting device for core-spun yarn machines that can improve reset efficiency. Summary of the Invention

[0009] To overcome the defects and shortcomings of existing technologies, this utility model provides a spandex yarn spool lifting device for core-spun yarn machines. Driven by an electromagnet, the device pushes the guide rod frame to move vertically upward smoothly. The guide rod frame is restricted to move vertically downward by a stop block, making the lifting more stable and controllable. The raised guide rod frame can be quickly lowered and reset by a descent button. The device is simple to drive, stable, and can improve the reset efficiency.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0021] As a preferred technical solution, the housing is provided with a third limiting block, and a third spring is provided on one side of the anti-elastic block. One end of the third spring is close to the anti-elastic block, and the other end of the third spring is close to the third limiting block of the housing. After the guide rod frame descends, the anti-elastic block is locked by the elastic force of the third spring, and the gear locks the second rack.

[0022] As a preferred technical solution, a pop-out button is also provided on one side of the anti-bullet block. When the pop-out button is pressed, it pushes the protrusion of the anti-bullet block away from the gear.

[0023] As a preferred technical solution, a limiting rod is provided on one side of the guide rod frame, and a limiting groove is provided on the housing. The limiting rod moves within the limiting groove, and the limiting rod and the limiting groove cooperate to form a travel limiting mechanism for the guide rod frame.

[0027] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0028] (1) This utility model pushes the guide rod frame to move vertically upward smoothly under the drive of the electromagnet. After the vertical upward movement is in place, the electromagnet is de-energized. The first rack of the guide rod frame is locked by the anti-reverse block, which restricts the vertical downward movement of the guide rod frame, making the lifting more stable and controllable. The raised guide rod frame can be quickly lowered and reset by the lowering button. Its drive is simple, smooth and can improve the reset efficiency.

[0029] (2) Based on the spring stop block to limit the movement of the guide rod after descent and reset, this utility model makes the overall control of the spandex yarn roll lifting device of the core-spun yarn machine more stable and can also prevent the guide rod from being started by mistake. The movement restriction of the guide rod after descent and reset can be quickly released by popping out the button.

[0030] (3) The limiting rod and the limiting groove of the housing form the travel limiting mechanism of the guide rod frame. When the lifting is raised to the position, the anti-reverse block locks the tray, and the electromagnet stops being energized. The control efficiency is high and the failure rate is low.

[0031] (4) The output shaft of the electromagnet of this utility model is provided with a first deep groove bearing and a second deep groove bearing on both sides of the vertical movement direction, and a third deep groove bearing on one side of the other end of the output shaft of the electromagnet, which is used to guide and limit the movement, so that the output shaft of the electromagnet keeps moving in the vertical direction, thereby improving the stability of the movement and the positioning accuracy.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0043] Example

[0044] like Figure 1 , Figure 2As shown, this embodiment provides a spandex filament spool lifting device for a core-spun yarn machine, including: a housing 1, a lifting frame, an electromagnet 2, a forward push block 3, a backstop block 4, a spring stop block 5, a gear 6, a lowering button 13, and a pop-out button 15;

[0045] like Figure 3 As shown, and in combination Figure 1 , Figure 2 As shown, the housing is provided with a sliding groove 32, a guide post mounting hole 17, a first limiting block 18, a second limiting block 24, a third limiting block 27, a first fixing post 22, a second fixing post 25, a first button mounting hole 14, a second button mounting hole 16, and a limiting groove 12;

[0046] like Figure 4 , Figure 5 As shown, the lifting frame includes a tray 7 and a guide rod frame 8. The tray 7 is connected to the guide rod frame 8. The guide rod frame 8 moves within the sliding groove 32 of the housing. A first rack 9 and a second rack 10 are provided on one side of the guide rod frame 8. The first rack is located at the upper end of the guide rod frame in the vertical direction of movement, and the second rack is located at the lower end of the guide rod frame in the vertical direction of movement.

[0047] One end of the output shaft of electromagnet 2 is connected to one end of the front push block 3. The other end (end) of the front push block 3 is close to the first rack 9 of the guide rod frame. A guide post is provided on one side of the front push block 3. The guide post is installed on the guide post mounting hole 17 of the housing. A first spring 19 is provided on the other side of the front push block 3. One end of the first spring 19 is close to the front push block 3, and the other end of the first spring 19 is close to the first limiting block 18 of the housing. When the electromagnet is energized, one end of the output shaft of electromagnet 2 pushes the front push block vertically upward. Under the limiting cooperation of the guide post and the first spring, the other end (end) of the front push block pushes the first rack of the guide rod frame upward. Each time the electromagnet pushes the front push block vertically upward, the first spring is compressed. After each push is completed, the first spring recovers and the front push block resets. Driven by the electromagnet, the guide rod frame is pushed vertically upward and moves smoothly.

[0048] The output shaft of the electromagnet 2 is provided with a first deep groove bearing 20 and a second deep groove bearing 21 on both sides of the vertical movement direction. The first deep groove bearing 20 and the second deep groove bearing 21 are fixedly connected to the housing 1 and are used to guide and limit the movement, so that the output shaft of the electromagnet remains in the vertical direction.

[0049] One end of the anti-reverse block 4 is movably connected to the first fixed post 22, and the other end (end) of the anti-reverse block 4 is close to the first rack of the guide rod frame. A down button is provided on one side of the anti-reverse block 4. The down button 13 is installed on the first button mounting hole 14 of the housing. A second spring 23 is provided on the other side of the anti-reverse block 4. One end of the second spring 23 is close to the anti-reverse block, and the other end of the second spring 23 is close to the second limiting block 24 of the housing. When the electromagnet is energized, the end of the push block pushes the first rack of the guide rod frame, and the guide rod frame moves vertically upward. At this time, the down button is in the reset state (not pressed). The protrusion of the first rack pushes the end of the anti-reverse block to move towards the second spring side. The second spring is compressed. After each push action is completed, the second spring recovers, and the anti-reverse block resets and locks the first rack of the guide rod frame, thereby restricting the vertical downward movement of the guide rod frame.

[0050] like Figure 6 , Figure 7 As shown, the lowering button 13 uses a manual push rod with a stepped shaft, that is, cylindrical blocks of different diameters are provided axially, with the smaller diameter at the end. The step of the stepped shaft is located at the edge of the anti-reverse block 4. After the lowering button is pressed, the cylindrical block with the larger diameter moves down, pushing the anti-reverse block to the side of the second spring. The second spring is compressed. At this time, the end of the anti-reverse block no longer abuts against the first rack, and the guide rod frame descends. It can be seen that after the power is cut off, the raised guide rod frame will not descend due to the action of the anti-reverse block. It can only descend after the lowering button is pressed, making the lifting more stable and controllable.

[0051] The other end of the output shaft of electromagnet 2 is connected to one end of the spring stop block 5. The other end of the spring stop block 5 is movably connected to the second fixed post 25. A protrusion is provided on one side of the spring stop block 5, which engages with gear 6. Gear 6 is installed inside the housing and meshes with the second rack 10 of the guide rod frame. A third spring 26 is provided on the other side of the spring stop block 5. One end of the third spring 26 is close to the spring stop block 5, and the other end of the third spring 26 is close to the third limiting block 27 of the housing. When the electromagnet is energized, the other end of the output shaft of the electromagnet moves vertically upward, carrying... One end of the movable stop block moves upward. Each time the electromagnet drives the stop block upward, the third spring is compressed. After the action is completed, the third spring returns to its original position, and the stop block is reset. When the electromagnet is de-energized, the guide rod frame is pressed down to the bottom, and the stop block is in the reset state. The protrusion of the stop block jams the gear, and the gear jams the second rack of the guide rod frame. At this time, the movement of the guide rod frame is restricted. That is, after the guide rod frame is pressed down to the bottom, if there is no other way to release the restriction (such as the electromagnet is energized or the pop-out button is pressed), the guide rod frame will not spring back, and the overall device is more stable.

[0052] like Figure 8 , Figure 9As shown, a pop-out button 15 is also provided on one side of the spring stop block 5. The pop-out button 15 is installed on the second button mounting hole 16 of the housing. The pop-out button 15 adopts a manual push rod with a stepped shaft, that is, cylindrical blocks of different diameters are provided in the axial direction, with the smaller diameter at the end and the step of the stepped shaft at the edge of the spring stop block. After the pop-out button is pressed, the cylindrical block with the larger diameter moves down, pushing the spring stop block to move towards the third spring side. The third spring is compressed. At this time, the protrusion of the spring stop block no longer jams the gear, and the guide rod frame is released from restriction.

[0053] A third deep groove bearing 28 is provided on one side of the other end of the output shaft of electromagnet 2. The third deep groove bearing 28 is fixedly connected to the housing and is used to guide and limit the movement, so that the other end of the output shaft of electromagnet remains in the vertical direction.

[0054] Combination Figure 4 , Figure 5 As shown, a limiting rod 11 is provided on one side of the guide rod frame. When the guide rod frame 8 moves vertically, the limiting rod 11 moves vertically as well. The rod body of the limiting rod 11 moves within the limiting groove 12 of the housing. When the limiting rod rises to the top of the limiting groove, the electromagnet stops being energized, indicating that the guide rod frame has risen to the designated position. The limiting rod and the limiting groove of the housing form the travel limiting mechanism of the guide rod frame. When the lifting reaches the designated position, the anti-reverse block locks the tray, and at the same time, the electromagnet stops being energized. The control efficiency is high and the failure rate is low.

[0055] Combination Figure 4 , Figure 5 As shown, the guide rod frame has an extension 29 at its end. The extension 29 is located at the bottom of the groove of the housing. A fourth spring 30 is sleeved on the extension. When the guide rod frame descends, the fourth spring plays a supporting and buffering role.

[0056] In this embodiment, the guide rod frame is also provided with a guide groove 31, and at least one deep groove bearing is provided in the guide groove 31. The deep groove bearing is fixedly connected to the housing and plays a guiding and limiting role, so that the guide rod frame moves vertically along the limiting groove.

[0057] In this embodiment, an electromagnet drive control board 33 is also provided to drive the electromagnet to work. The electromagnet drive control board is connected to an external 24V power supply. When a sensor signal is received, the electromagnet drive control board only needs to be powered on for 1 second. The electromagnet drive control board continuously supplies power to the electromagnet 10 times with a 50% duty cycle to complete the lifting action. The electromagnet works based on the electromagnet drive control board, without the need for a reducer module. The control is simple and the failure rate is low.

[0058] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
