Description

Technical Field

[0001] This utility model relates to the field of dyeing and finishing equipment technology, and in particular to a powder turnover device for dyeing and finishing equipment. Background Technology

[0002] In the production process of dyeing and finishing equipment, the precise delivery of powder is crucial to ensuring dyeing and finishing quality and production stability. Currently, most common powder conveying equipment adopts a direct dropping method for powder dissolution and conveying or direct powder delivery. This type of equipment mainly consists of a storage container and a discharge channel. The storage container is used to store the powder, and the discharge channel is connected to the bottom of the storage container, allowing the powder to fall directly into the storage container by gravity.

[0003] However, this direct-feeding conveying method has the following drawbacks: Due to the lack of an effective metering and control structure, the powder relies solely on gravity during its descent, making it difficult to accurately control the weight of powder conveyed each time, easily leading to over- or under-feeding. In dyeing and finishing processes, inaccurate powder supply directly affects the uniformity and color stability of dyeing, resulting in inconsistent product quality. Furthermore, this conveying method cannot flexibly adjust the conveying volume according to actual production needs, and the continuity and precision of the transportation process are insufficient, making it difficult to meet the high-precision and continuous powder conveying requirements of dyeing and finishing equipment, thus affecting the overall production efficiency and economic benefits of the dyeing and finishing equipment. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a powder turnover device for dyeing and finishing equipment, including a turnover tank and a discharge mechanism connected to the turnover tank. The turnover tank is provided with a receiving cavity in which the powder is stored. The discharge mechanism includes a discharge cylinder connected to the receiving cavity.

[0006] The discharge mechanism further includes a screw rod and a rotary drive component that is driven by the screw rod. The screw rod is located inside the discharge cylinder, and the central axis of the screw rod is parallel to the central axis of the discharge cylinder. The bottom of the discharge cylinder is connected to the turnover tank and extends upward at an incline. The top of the discharge cylinder is provided with a discharge pipe.

[0007] A weighing sensor is provided at the bottom of the turnover tank or at the bottom of the screw rod.

[0008] As an improvement to the above solution, the screw rod includes a rod body and a pusher plate. The rod body is connected to the rotary drive component. The pusher plate protrudes from the surface of the rod body and extends spirally along the axial direction of the rod body. The rotation direction of the screw rod can push the powder from the bottom of the discharge cylinder to the top of the discharge cylinder.

[0009] As an improvement to the above solution, the powder turnover equipment for dyeing and finishing equipment further includes a gate mechanism. The gate mechanism includes a discharge drive and a gate plate that is pulverizedly connected to the discharge drive. The gate plate is disposed between the turnover tank and the discharge cylinder. The discharge drive can drive the gate plate to move between the positions of closing the outlet of the turnover tank and sealing the outlet of the turnover tank.

[0010] As an improvement to the above solution, the bottom of the turnover tank is provided with a first tube, the upper side of the discharge cylinder is provided with a second tube, the gate is disposed between the first tube and the second tube, and the discharge drive can drive the gate to move between a position that blocks the communication between the first tube and the second tube and a position that allows the first tube and the second tube to communicate.

[0011] As an improvement to the above solution, the gate mechanism further includes a first fixing plate and a second fixing plate. The first fixing plate is fixed to the bottom of the first tube body, and the second fixing plate is fixed to the top of the second tube body. The material feeding drive can drive the gate to move between the first fixing plate and the second fixing plate.

[0012] As an improvement to the above solution, a connecting rod is also provided between the discharge cylinder and the turnover tank. One end of the connecting rod is fixed to the side wall of the turnover tank, and the other end of the connecting rod is fixed to the side wall of the discharge cylinder.

[0013] As an improvement to the above solution, the tilt angle of the discharge cylinder is in the range of 30°-65°.

[0014] As an improvement to the above solution, the discharge pipe is vertically installed at the top of the discharge cylinder and communicates with the inner cavity of the discharge cylinder.

[0015] As an improvement to the above solution, the bottom of the turnover tank is provided with an accumulation section, the longitudinal section of which has an inverted trapezoidal structure that is wider at the top and narrower at the bottom, and a vibrator is provided on the outer wall of the accumulation section.

[0016] As an improvement to the above solution, the bottom of the turnover tank is provided with multiple casters.

[0017] Implementing this utility model has the following beneficial effects:

[0018] This utility model relates to a powder handling device for dyeing and finishing equipment, which includes a handling tank and a discharging mechanism. The handling tank has a receiving cavity in which the powder is stored. The discharging mechanism includes a discharging cylinder, a screw rod, and a rotary drive component connected to the screw rod. The bottom of the discharging cylinder is connected to the handling tank and extends upward at an incline. When conveying powder, the powder falls from the receiving cavity into the discharging cylinder. The screw rod then tilts and conveys the powder from the bottom to the top of the discharging cylinder.

[0020] Figure 2 yes Figure 1 A magnified view of part A in the image. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0022] See Figure 1 and Figure 2 This utility model discloses a powder handling device for dyeing and finishing equipment, including a handling tank 1 and a discharge mechanism 2 connected to the handling tank 1. The handling tank 1 has a receiving cavity 11, in which the powder is stored. The handling tank 1 serves as a powder storage unit, and its internal receiving cavity 11 provides storage space for the powder. The discharge mechanism 2 includes a discharge cylinder 21, which is connected to the receiving cavity 11. When powder needs to be transported, the powder falls from the receiving cavity 11 into the discharge cylinder 21 connected to it by gravity.

[0023] The discharge mechanism 2 also includes a screw rod 22 and a rotary drive component 23 connected to the screw rod 22. The screw rod 22 is located inside the discharge cylinder 21 and can rotate at a stable speed under the drive of the rotary drive component 23. The central axis of the screw rod 22 is parallel to the central axis of the discharge cylinder 21. The bottom of the discharge cylinder 21 is connected to the turnover tank 1 and extends upward at an incline. During the process of conveying powder from the bottom to the top of the discharge cylinder 21, due to the incline of the discharge cylinder 21, the powder can fully contact the working surface of the screw rod 22. Compared with the existing direct dropping method, this avoids the situation where the powder is difficult to control due to free fall under gravity. The screw rod 22 pushes the powder in a slow, continuous and stable manner, so that the amount of powder conveyed each time can be precisely controlled, effectively overcoming the problem that existing equipment cannot accurately control the weight of the powder. The top of the discharge cylinder 21 is provided with a discharge pipe 24. After the powder is pushed to the top, it falls from the discharge pipe 24 into an external container.

[0024] A weighing sensor is installed at the bottom of the transfer tank 1 or the bottom of the screw rod 22 to monitor the weight change of the powder in real time. By feeding the weight information back to the control system, the rotation speed of the rotary drive 23 is adjusted, thereby achieving more precise control over the powder output, further improving the accuracy of powder output, and ensuring the continuity and precision of the transportation process.

[0025] The beneficial effects of this utility model embodiment are as follows:

[0026] This utility model embodiment of a powder handling device for dyeing and finishing equipment includes a handling tank 1 and a discharging mechanism 2. The handling tank 1 has a receiving cavity 11 where the powder is stored. The discharging mechanism 2 includes a discharging cylinder 21, a screw rod 22, and a rotary drive component 23 connected to the screw rod 22. The bottom of the discharging cylinder 21 is connected to the handling tank 1 and extends upwards at an angle. When conveying powder, the powder falls from the receiving cavity 11 into the discharging cylinder 21, and the screw rod 22 discharges the powder. The powder is conveyed at an angle from the bottom to the top of the discharge cylinder 21. During the inclined conveying process, it is ensured that the powder fully contacts the working surface of the screw rod 22. Combined with the slow, continuous, and stable conveying characteristics of the screw rod 22, the screw rod 22 can accurately and continuously control the amount of powder discharged. With the help of the weighing sensor at the bottom of the transfer tank 1 or the bottom of the screw rod 22, the accuracy of powder discharge can be further improved, thereby achieving precise control of the weight of the conveyed powder and improving the continuity and precision of the transportation process.

[0027] The spiral rod 22 includes a rod body 221 and a pusher plate 222. The rod body 221 is connected to the rotary drive 23. During actual operation, after the rotary drive 23 starts, it stably transmits power to the rod body 221, which is connected to it, causing the spiral rod 22 to start rotating. Since the bottom of the discharge cylinder 21 is connected to the turnover tank 1 and is inclined upwards, the powder naturally slides down to the bottom of the discharge cylinder 21 under the action of gravity and will directly contact the rotating pusher plate 222. The pusher plate 222 protrudes from the surface of the rod body 221 and extends spirally along the axial direction of the rod body 221. The rotation direction of the spiral rod 22 can push the powder from the bottom to the top of the discharge cylinder 21. The pusher plate 222, by virtue of its spiral upward trajectory, generates an upward thrust on the powder along the axis of the discharge cylinder 21 during rotation. As the screw 22 continues to rotate, this thrust acts continuously and stably on the powder, gradually pushing the powder from the bottom to the top of the discharge cylinder 21. During this process, the contact between the pusher plate 222 and the powder is not a simple mechanical push, but rather, through the screw structure, the powder can form an orderly flow state within the discharge cylinder 21 when it is pushed.

[0028] When the powder demand of the dyeing and finishing equipment changes, the rotary drive 23 can adjust the rotation speed of the screw rod 22 to change the rotational speed. At this time, the pushing rhythm of the pusher plate 222 also changes accordingly. Due to its unique spiral structure, regardless of the rotational speed adjustment, it can ensure a uniform and stable pushing force on the powder. At low speeds, the pusher plate 222 can precisely control the delivery of small amounts of powder, avoiding excessive powder supply that could affect dyeing and finishing quality; at high speeds, it can also ensure continuous and stable powder output, meeting the high-efficiency production requirements of the equipment.

[0029] The powder turnover device for dyeing and finishing equipment also includes a gate mechanism 3. The gate mechanism 3 includes a discharge drive 31 and a gate 32 pulverizedly connected to the discharge drive 31. The gate 32 is disposed between the turnover tank 1 and the discharge cylinder 21. The discharge drive 31 can drive the gate 32 to move between positions that close the outlet of the turnover tank 1 and positions that seal the outlet of the turnover tank 1. In actual operation, when the dyeing and finishing equipment issues a feeding command, the discharge drive 31 drives the gate 32 connected to it through a transmission structure, causing it to move from the position of sealing the outlet of the turnover tank 1 towards the opening direction. As the gate 32 moves, the channel between the turnover tank 1 and the discharge cylinder 21 gradually connects. Under the action of gravity, the powder in the receiving cavity 11 falls smoothly into the bottom of the discharge cylinder 21 and contacts the pusher plate 222 on the rotating screw 22. Then, it is spirally conveyed to the discharge pipe 24 at the top of the discharge cylinder 21, completing the feeding process to the dyeing and finishing equipment.

[0030] When the discharge task is completed, or when the dyeing and finishing equipment does not require powder supply temporarily, the discharge drive 31 actuates again, driving the gate 32 to move in the opposite direction, returning it to the position of sealing the outlet of the transfer tank 1. At this time, the gate 32 is tightly fitted with the edge of the outlet of the transfer tank 1, forming a reliable sealing structure. This not only completely blocks the falling path of the powder, preventing accidental leakage when the powder is not needed, but also effectively isolates the interior of the transfer tank 1 from the external environment. In actual production environments, the air often contains a certain amount of moisture and impurities. If the outlet of the transfer tank 1 is exposed for a long time, the powder easily absorbs moisture, causing clumping at the outlet of the transfer tank 1. The gate mechanism 3, through this sealing and isolation method, avoids contact between the powder and the external environment, effectively preventing the powder from clumping. This ensures that when feeding powder again, the powder can smoothly fall from the transfer tank 1 into the discharge cylinder 21 without affecting the discharge accuracy due to clumping and blockage, thus ensuring that the entire powder transfer equipment continuously and stably provides accurate and reliable powder delivery to the dyeing and finishing equipment.

[0031] The bottom of the transfer tank 1 is provided with a first tube 12, and the upper side of the discharge cylinder 21 is provided with a second tube 25. A gate 32 is disposed between the first tube 12 and the second tube 25. The discharge drive 31 can drive the gate 32 to move between a position that blocks the communication between the first tube 12 and the second tube 25 and a position that allows the first tube 12 and the second tube 25 to communicate. When the dyeing and finishing equipment needs to supply material, the control system sends a command to the discharge drive 31, which drives the gate 32 to slide along a preset track from the position that blocks the communication between the first tube 12 and the second tube 25 to the position that allows them to communicate. During the sliding process, the gate 32 gradually removes its obstruction of the tube joint, thus forming a through channel between the first tube 12 and the second tube 25.

[0032] The gate mechanism 3 further includes a first fixing plate 33 and a second fixing plate 34. The first fixing plate 33 is fixed to the bottom of the first tube 12, and the second fixing plate 34 is fixed to the top of the second tube 25. The feeding drive 31 can drive the gate 32 to move between the first fixing plate 33 and the second fixing plate 34. The first fixing plate 33 is tightly fixed to the bottom of the first tube 12, which can be achieved by welding to form a strong integral structure through continuous welding, ensuring that it will not loosen during long-term use; alternatively, it can be connected by bolts, with mounting holes made at corresponding positions on the bottom of the first tube 12 and the first fixing plate 33, and the two tightly connected by high-strength bolts for easy subsequent disassembly and maintenance. Similarly, the second fixing plate 34 is fixed to the top of the second tube 25 in a similar way to ensure its stability. When the feeding drive 31 drives the gate 32 to move, the first fixing plate 33 and the second fixing plate 34 form a guide groove, which can guide the movement direction of the gate 32, so that it can only move along the radial direction of the first tube 12 and the second tube 25.

[0033] A connecting rod 13 is also provided between the discharge cylinder 21 and the turnover tank 1. One end of the connecting rod 13 is fixed to the side wall of the turnover tank 1, and the other end of the connecting rod 13 is fixed to the side wall of the discharge cylinder 21. One end of the connecting rod 13 is firmly fixed to the side wall of the turnover tank 1 by welding or bolting, and the other end is also reliably fixed to the side wall of the discharge cylinder 21. This connection method makes the turnover tank 1 and the discharge cylinder 21 form a rigid whole, effectively enhancing the supporting strength of the discharge cylinder 21.

[0034] The tilt angle of the discharge cylinder 21 ranges from 30° to 65°. When the tilt angle of the discharge cylinder 21 is 30°, the contact time between the powder and the working surface of the screw rod 22 is relatively long during the powder conveying process, allowing the screw rod 22 to more effectively control the powder conveying speed and discharge volume, which is especially suitable for dyeing and finishing processes with high powder conveying accuracy requirements. When the tilt angle of the discharge cylinder 21 is 65°, the powder can slide to the bottom of the discharge cylinder 21 more quickly under the action of gravity, improving the powder conveying efficiency, which is suitable for dyeing and finishing production links with certain requirements for conveying speed. By setting the tilt angle of the discharge cylinder 21 within the range of 30°-65°, the powder conveying accuracy and efficiency can be flexibly adjusted according to different dyeing and finishing process requirements, making the powder turnover equipment more adaptable and practical.

[0035] The discharge pipe 24 is vertically installed at the top of the discharge cylinder 21 and communicates with the inner cavity of the discharge cylinder 21 to ensure that the powder falls smoothly.

[0036] The bottom of the transfer tank 1 is provided with an aggregation section 14. The longitudinal section of the aggregation section 14 is an inverted trapezoidal structure that is wider at the top and narrower at the bottom. This allows the powder in the transfer tank 1 to naturally gather towards the bottom of the aggregation section 14 under the action of gravity, facilitating the smooth flow of the powder from the transfer tank 1 into the discharge cylinder 21. Simultaneously, a vibrator 15 is provided on the outer wall of the aggregation section 14. During discharge, the vibrator 15 accelerates the rate at which the powder falls from the aggregation section 14. Furthermore, when powder accumulates or becomes blocked in the transfer tank 1, the vibrator 15 is activated, vibrating the outer wall of the aggregation section 14 to loosen the powder and allow it to flow smoothly towards the bottom of the aggregation section 14.

[0037] The bottom of the turnover tank 1 is equipped with multiple casters 16. When it is necessary to adjust the position of the powder turnover equipment or move it to a different working area, the operator can easily move the equipment to the required position by pushing the turnover tank 1 and using the casters 16 at the bottom.

[0038] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
