Description

Technical Field

[0001] This utility model belongs to the field of textile equipment technology, specifically relating to a constant pressure energy-saving system for a cotton suction device. Background Technology

[0002] In the spinning process, a cotton suction device is usually needed to pick up and recover broken rovings. Existing cotton suction devices typically use a fan to generate negative pressure and then use a flute to suck up the broken yarn. However, in order to ensure the cotton suction effect of the flute, the fan needs to operate at a constant power for a long time. When there are few broken yarns, it is easy to waste electrical energy. If the power of the fan is reduced, the cotton suction effect cannot be guaranteed. Therefore, there is an urgent need to design a constant pressure energy-saving cotton suction device system that can ensure constant cotton suction pressure and save electrical energy. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model discloses a constant pressure energy-saving system for a cotton suction device, and specifically discloses the following technical solutions:

[0004] A constant-pressure energy-saving system for a cotton suction device includes a movable frame with a horizontal displacement mechanism mounted on it. An installation plate is fixedly connected to the output end of the horizontal displacement mechanism, and an adjustable suction tube is fixedly connected to the installation plate. The adjustable suction tube includes an inner tube and an outer tube slidably sleeved outside the inner tube. Both ends of the inner tube are sealed. A plurality of first suction holes are evenly spaced at the bottom end of the inner tube. A second suction hole is provided at the bottom end of the outer tube corresponding to each of the first suction holes. A telescopic mechanism is fixedly connected to one end of the inner tube, with one end fixedly connected to the end of the inner tube and the other end fixedly connected to the end face of the outer tube via a connecting plate. The air outlet of the inner tube is connected to one side of a cotton suction box fixed to the top of the movable frame via a suction pipe.

[0006] Furthermore, the telescopic mechanism employs a first hydraulic telescopic rod.

[0007] Furthermore, the mobile frame includes two parallel bases, each base having a travel wheel installed at its bottom end and a second hydraulic telescopic rod fixedly connected to its top end. Each second hydraulic telescopic rod has a U-shaped seat fixedly connected to its top end, and the top ends of the two U-shaped seats are fixedly connected by a top plate. The cotton suction box and the cotton suction fan are both fixedly installed on the top end of the top plate, and the horizontal displacement mechanism is installed between the two U-shaped seats.

[0008] Furthermore, the horizontal displacement mechanism includes a lead screw, a slide block, and a first drive motor. The lead screw is rotatably connected between the two U-shaped seats.

[0010] Furthermore, a filter screen is provided at the connection between the cotton suction box and the suction pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The adjustable cotton suction tube of this utility model includes an inner tube and an outer tube that is slidably sleeved outside the inner tube. The outer tube is driven to slide relative to the inner tube by a telescopic mechanism, which can control the effective area of ​​the first cotton suction hole on the inner tube.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-7A constant-pressure energy-saving system for a cotton suction device includes a movable frame with a horizontal displacement mechanism mounted on it. The output end of the horizontal displacement mechanism is fixedly connected to a mounting plate 1. An adjustable cotton suction tube is fixedly connected to the mounting plate 1. The adjustable cotton suction tube includes an inner tube 2 and an outer tube 3 slidably sleeved outside the inner tube 2. Both ends of the inner tube 2 are sealed. A plurality of first cotton suction holes 4 are evenly spaced at the bottom end of the inner tube 2. A second cotton suction hole 5 is provided at the bottom end of the outer tube 3 corresponding to each first cotton suction hole 4. One end of the inner tube 2 is fixedly connected to an extension... The telescopic mechanism has one end fixedly connected to the end of the inner tube 2, and the other end fixedly connected to the end face of the outer tube 3 through the connecting plate 6. The air outlet of the inner tube 2 is connected to one side of the suction box 8 fixed on the top of the mobile frame through the suction pipe 7. The top of the outer tube 3 is provided with a strip hole for the suction pipe 7 to slide. The other side of the suction box 8 is connected to the suction fan 10 through the suction pipe 9. The suction pipe 7 is connected to the vacuum gauge 11. The vacuum gauge 11, the telescopic mechanism and the suction fan 10 are all electrically connected to the PLC controller fixed on the suction box 8.

[0023] When there are many broken yarns, the suction fan 10 operates at a higher power. At this time, the first suction hole 4 and the second suction hole 5 are completely aligned, and the effective area of ​​the first suction hole 4 is the largest. When there are few broken yarns, the power of the suction fan 10 can be reduced. At this time, the telescopic mechanism extends and drives the outer tube 3 to slide relative to the inner tube 2, so that the first suction hole 4 is gradually covered to ensure that the negative pressure in the inner tube 2 is consistent with the previous one, so as to achieve the same suction effect and save power.

[0024] In this embodiment, the distance between two adjacent first suction holes 4 is greater than the length of the first suction hole 4. The lengths of the first suction holes 4 and the second suction holes 5 are the same. The spacing between two adjacent first suction holes 4 is the same as the spacing between two adjacent second suction holes 5, so as to ensure that the effective exposure area of ​​several first suction holes 4 can increase or decrease synchronously.

[0025] In this embodiment, the telescopic mechanism uses a first hydraulic telescopic rod 12. In other embodiments, the telescopic mechanism may also use a linear stepper motor.

[0026] In this embodiment, the mobile frame includes two parallel bases 13. Each base 13 is equipped with a travel wheel 14 at its bottom end. The number of travel wheels 14 installed at the bottom end of each base 13 is at least two, so that the two bases 13 can form a stable support structure. Each base 13 is fixedly connected to a second hydraulic telescopic rod 15 at its top end. Each second hydraulic telescopic rod 15 is fixedly connected to a U-shaped seat 16 at its top end. The top ends of the two U-shaped seats 16 are fixedly connected through a top plate 17. The cotton suction box 8 and the cotton suction fan 10 are both fixedly installed at the top end of the top plate 17. The horizontal displacement mechanism is installed between the two U-shaped seats 16.

[0027] In this embodiment, the horizontal displacement mechanism includes a lead screw 18, a slide 19, and a first drive motor 20. The lead screw 18 is rotatably connected between two U-shaped seats 16, with one end of the lead screw 18 passing through one of the U-shaped seats 16 and fixedly connected to the output shaft of the first drive motor 20. The slide 19 is threadedly connected to the lead screw 18, and the top plane of the slide 19 contacts the bottom plane of the top plate 17. The mounting plate 1 is fixedly connected to the bottom end of the slide 19. The first drive motor 20 can drive the lead screw 18 to rotate, thereby driving the slide 19, the mounting plate 1, and the adjustable suction tube to move horizontally, so as to realize the suction operation at different positions.

[0028] In this embodiment, a motor mounting box is fixedly connected to the top wall inside the cotton suction box 8. A second drive motor 21 is installed inside the motor mounting box. The output shaft of the second drive motor 21 passes downward through the bottom wall of the motor mounting box and is fixedly connected to a rotating shaft 22. A spiral pressure plate 23 is provided on the rotating shaft 22. The bottom end of the rotating shaft 22 is rotatably connected to a rotating seat 24 located in the lower part of the cotton suction box 8. Several connecting rods 25 are fixedly connected circumferentially on the outer wall of the rotating seat 24. The other end of the connecting rods 25 is fixedly connected to the side wall of the cotton suction box 8. There is a certain distance between the rotating seat 24 and the bottom wall of the cotton suction box 8. The second drive motor 21 can drive the rotating shaft 22 to rotate, thereby driving the spiral pressure plate 23 to rotate continuously, so as to continuously compress the broken yarn in the upper part of the cotton suction box 8 downward, thereby providing space for the newly entered broken yarn in the cotton suction box 8.

[0029] In this embodiment, a filter screen 26 is provided at the connection between the cotton suction box 8 and the suction pipe 9 to prevent broken yarn from entering the cotton suction fan 10.

[0030] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
