Description

Technical Field

[0001] This utility model relates to the field of yarn humidification technology, specifically a pre-treatment humidification device for spinning. Background Technology

[0002] Yarn pre-wetting is a common process in spinning. It involves pre-wetting the yarn by manual or machine humidification to improve the softness, smoothness, and conductivity of the fibers, while reducing fiber breakage and damage.

[0003] Because manual humidification is inefficient and uneven, most companies now use humidification equipment for this process. For example, patent application number CN202420940376.X, entitled "Spinning Equipment for Producing Cotton-like Polyester Yarn," discloses a device for steam humidifying yarn. Patent application number CN202323066108.4, entitled "A Pretreatment Wetting Device for Spinning", discloses a device for spraying water to humidify yarn.

[0004] Existing technology can effectively humidify yarn and remove surface dust, but it lacks effective measures for dust and lint washed away in subsequent processing. Since the filtered water needs to be recycled, directly removing the filter plate for replacement will cause the dirt accumulated in front of the filter plate to enter the water tank, affecting water quality.

[0005] In addition, existing methods of spraying water to wet yarn mostly involve spraying water from top to bottom, while steam humidification methods mostly involve humidifying the yarn from bottom to top. This one-way humidification method has a poor effect on the other side of the yarn and requires a long time to complete the humidification process, which affects the humidification efficiency. Summary of the Invention

[0006] To address the technical problems existing in the background art, this utility model provides a pretreatment wetting device for spinning.

[0007] The technical solution of this utility model is as follows: A pretreatment wetting device for spinning includes an operating box, with guide cylinders at the upper part of both ends of its inner cavity and a water tank at the lower part. A water pump and a water spray pipe are connected to the outside of the water tank. A water return frame is provided on the outside of the operating box, and a squeezing cylinder is provided above the water return frame. The water return frame is connected to the water tank. The yarn passes between the two guide cylinders, and the water spray pipe is used to spray water onto it. All of these are existing technologies.

[0008] The inventive point of this invention is that an inclined water return plate is provided in the inner cavity of the control box between the guide cylinder and the water tank, the side of the water return plate near the water return frame is the lowest point, and a first water inlet is left between the water return plate and the water return frame. A buffer plate is installed below the first water inlet. The buffer plate is tilted, with its lowest point connected to the inner wall of the control box and its highest point connected to the second water inlet at the top of the water tank. A filter device is installed above the second inlet. The filter device includes a filter plate that is movable at the rear. The bottom of the filter plate abuts against the highest point of the buffer plate. The buffer plate is sealed with side baffles on both sides. The front of the side baffles is connected to the filter device, and the rear is connected to the inner wall of the control box. All connections are equipped with seals. The control panel has a maintenance door on the side panel.

[0009] As the humidification process continues, more and more dust and lint will be washed down and clog the front of the filter plate. Simply scraping the filter plate back and forth cannot solve the fundamental problem, and may even push the dirt into the water tank. Therefore, the main design concept of this utility model is to facilitate the replacement of the filter plate while preventing dirt from entering the water tank.

[0010] The inclined buffer plate creates a temporary storage area for contaminants, preventing them from clogging the filter plate. Contaminants can be cleaned by periodically opening the maintenance door and removing the side baffle. During cleaning, as the water level on the buffer plate decreases, the filter plate at the higher point detaches from the contaminants, preventing contaminants from entering the rear water tank during replacement.

[0011] In one embodiment, the buffer plate includes a flat section at the front and an inclined section at the rear. The inclined section is inclined from front to back, the rear section is fixed to the inner wall of the operating box, and the flat section is flush with the top of the water tank.

[0012] Furthermore, the filter plate of the filter device is vertically positioned above the flat portion of the buffer plate.

[0013] In one embodiment, the filtration device includes a filter plate, a first connecting plate, and a second connecting plate. The first connecting plate is a bent plate, with one end connected to the front end of the second water inlet and the other end located above the straight portion of the buffer plate. The filter plate is movably connected to the first connecting plate through the second connecting plate.

[0014] As a preferred embodiment, a sliding port matching the length of the filter plate is provided at the rear of the first connecting plate, allowing the filter plate to be slid backward for removal. This further prevents dirt from the bottom of the filter plate from accidentally entering the rear water tank when replacing the filter plate.

[0015] As a further preferred option, rubber seals are provided around the filter plate at the contact points with the first connecting plate to enhance the sealing effect and prevent dirt from passing through the filter plate from all sides.

[0016] To better guide the water from the return water frame into the water tank, a baffle plate is connected between the return water frame and the buffer plate.

[0017] Furthermore, the rear part of the side baffle is sealed to the guide plate.

[0018] As another inventive feature of this invention, the water tank is connected to water pumps on both sides of the control box via water guide pipes. The other end of each water pump is connected to a spray pipe, which is also connected to the side of the control box. This allows for spraying water onto the yarn passing between the two guide cylinders. By spraying water onto the yarn from the side, water mist can quickly cover the yarn surface, improving wetting efficiency.

[0019] In one implementation, each water spray pipe is equipped with one or more nozzles in a horizontal direction. In this case, the nozzles must be positioned directly opposite the location where the yarn passes.

[0020] In another implementation, each spray pipe is equipped with two rows of nozzles, one above the other, located on the upper and lower sides of the yarn's path, angled towards the yarn. This ensures complete coverage of the yarn's outer surface, further improving wetting efficiency.

[0021] The main design concept of this utility model for a pretreatment wetting device for spinning is to facilitate the replacement of filter plates while preventing dirt from entering the water tank.

[0022] The inclined buffer plate creates a temporary storage area for contaminants, preventing them from clogging the filter plate. Contaminants can be cleaned by periodically opening the maintenance door and removing the side baffle. During cleaning, as the water level on the buffer plate decreases, the filter plate at the higher point detaches from the contaminants, preventing contaminants from entering the rear water tank during replacement.

[0023] In addition, water is sprayed onto the yarn from the side to quickly cover the yarn surface with water mist, thereby improving wetting efficiency. Attached Figure Description

[0025] Example 1 This embodiment provides a pretreatment wetting device for spinning, including an operation box 1. The operation box 1 has a square structure, with guide cylinders 2 installed at the upper parts of both ends of its inner cavity. Two guide cylinders 2 are arranged in a group, with the middle section for the yarn to pass through. A water tank 12 is installed at the lower part of the inner cavity of the operation box 1. A water pump 5 and a spray pipe 7 are connected to the outside of the water tank 12. A return water frame 4 is installed on the outside of the operation box 1. A squeezing cylinder 3 is installed above the return water frame 4. The squeezing cylinder 3 includes two cylinders arranged vertically, driven to rotate by a servo motor and a transmission mechanism (not shown in the figure). After the yarn is wetted, excess water is squeezed out at the squeezing cylinder 3. The front of the return water frame 4 has an opening where it connects to the operation box 1, communicating with the water tank 12 through this opening, so that the water in the return water frame 4 flows back into the water tank 12. The yarn passes between the two guide cylinders 2, and the water spray pipe 7 is used to spray water onto it. This is all prior art, for example, patent application number CN202323066108.4, patent titled "A Pretreatment Wetting Device for Spinning". Since the inventive point of this utility model is not in this respect, this prior art will not be described in detail.

[0026] As the humidification process continues, more and more dust and lint will be washed down and clog the front of the filter plate 161. Simply scraping the filter plate 161 back and forth cannot solve the fundamental problem, and may even push the dirt into the water tank 12. Therefore, the main design concept of this utility model is to facilitate the replacement of the filter plate 161 while preventing dirt from entering the water tank 12.

[0027] See Figures 1-3 The invention is that an inclined return water plate 11 is provided in the inner cavity of the operation box 1 between the guide cylinder 2 and the water tank 12. The side of the return water plate 11 closest to the return water frame 4 is the lowest point, that is, the return water plate 11 is higher in the front and lower in the back, and a first water inlet is left between the rear part of the return water plate 11 and the return water frame 4.

[0028] Preferably, the lowest point of the return water plate 11 is at the same height as the lowest point of the return water frame 4.

[0029] A buffer plate 13 is installed below the first water inlet. The buffer plate 13 is also inclined with the front higher than the back. The lower point is connected to the inner wall of the control box 1, and the higher point is connected to the second water inlet at the top of the water tank 12.

[0030] To better guide the water from the return water frame 4 into the water tank 12, a guide plate 14 is connected between the return water frame 4 and the two side edges of the buffer plate 13, see [reference]. Figure 3 As shown.

[0031] A filter device 16 is provided above the second water inlet. The filter device 16 includes a filter plate 161 that is movably arranged at the rear. The bottom of the filter plate 161 abuts against the high point of the buffer plate 13.

[0032] Side baffles 15 are sealed to the left and right sides of the buffer plate 13. The front of the side baffle 15 is connected to the filter device 16, and the rear is movably connected to the guide plate 14 connected to the inner wall of the control box 1. Rubber seals are provided at the connection points of the side baffle 15 with the buffer plate 13, the guide plate 14 and the filter device 16 to enhance the sealing effect and prevent dirt from passing through the filter plate 161 from all sides.

[0033] See Figure 4 The side baffle 15 can be a square plate. Rubber seals are pre-attached to the corresponding connection positions of the side baffle 15. Bolt connection holes are provided at the connection points between the side baffle 15 and the guide plate 14, the buffer plate 13, and the filter device 16. Holes can be directly drilled on the guide plate 14, the buffer plate 13, and the filter device 16, or bolt connection plates can be welded on, with corresponding bolt connection holes provided on the bolt connection plates, such as the structure shown in the buffer plate 13.

[0034] Through the above design, a temporary dirt storage area can be formed in the low-lying area of ​​the inclined buffer plate 13 to prevent dirt from clogging the filter plate 161.

[0035] Furthermore, the width dimensions of both the water tank 12 and the buffer plate 13 perpendicular to the yarn travel direction are smaller than the width dimension of the operating box 1, see [reference]. Figure 2 As shown, the control box 1 has a maintenance door 8 at the side baffle 15 position. The maintenance door 8 can be opened periodically to remove the side baffle 15 for easy cleaning of contaminants. During cleaning, as the water level on the buffer plate 13 decreases, the filter plate 161 at the highest point detaches from the contaminants, preventing contaminants from entering the rear water tank 12 during replacement.

[0036] See below. Figure 3 In one embodiment, the buffer plate 13 includes a flat section at the front and an inclined section at the rear. The inclined section is inclined from front to back, and the rear section is fixed to the inner wall of the operation box 1. The flat section is flush with the top of the water tank 12, and the second water inlet of the water tank 12 is located at the top of the rear end.

[0037] Furthermore, the filter plate 161 of the filter device 16 is vertically arranged above the flat portion of the buffer plate 13.

[0038] In this embodiment, the filtration device 16 includes a filter plate 161, a first connecting plate 162, and a second connecting plate 163.

[0039] The first connecting plate 162 is a 90-degree bent plate, with one end vertically connected to the front end of the second inlet and the other end located above the straight part of the buffer plate 13 and arranged parallel to the straight part. The filter plate 161 is movably connected to the first connecting plate 162 through the second connecting plate 163.

[0040] As a preferred embodiment, the rear of the first connecting plate 162 has a sliding outlet that matches the length of the filter plate 161, allowing the filter plate 161 to be slid backward for removal. This further prevents dirt from the bottom of the filter plate 161 from accidentally entering the rear water tank 12 when replacing the filter plate 161.

[0041] The second connecting plate 163 is connected to the front of the sliding outlet of the first connecting plate 162.

[0042] The first connecting plate 162 has side sealing plates on both sides, with bolt connection holes for bolt connection with the side baffle 15.

[0043] Example 2 See Figure 5 As another inventive feature of this utility model, the water tank 12 is connected to the water pumps 5 on both sides of the control box 1 via water guide pipes 6. The other end of the water pump 5 is connected to a spray pipe 7, which is connected to the side of the control box 1, enabling water spraying operation on the yarn passing between the two guide cylinders 2. By spraying water on the yarn from the side, water mist can be quickly covered on the yarn surface, improving wetting efficiency.

[0044] Furthermore, each water spray pipe 7 is equipped with one or more nozzles in the horizontal direction. In this case, the nozzle position must be directly opposite the location where the yarn passes, see [reference needed]. Figure 5 As shown.

[0045] As another implementation, the water spray pipe 7 can also be configured in other ways. For example, each water spray pipe 7 can be equipped with two rows of nozzles, one above the other, located on the upper and lower sides of the yarn's path, and angled towards the yarn. This ensures complete coverage of the yarn's outer surface, further improving wetting efficiency.
