Description

Technical Field

[0001] This application relates to the field of dyeing equipment, and more particularly to a device for quantitatively adding auxiliaries to a dyeing machine. Background Technology

[0002] Among bast fibers, cellulose fibers such as flax and ramie have natural advantages such as rapid moisture absorption and heat dissipation, and antibacterial and antifungal properties. However, their molecular structure contains many hydroxyl groups and crystalline regions, which can cause itching and a rough feel in knitted fabrics. The "Research and Development of Double Mercerizing Non-Irritation Dyeing and Finishing Technology for Bast Fiber Knitted Fabrics" aims to overcome this problem by improving the surface properties of the fabric through double mercerizing treatment. In the entire dyeing and finishing process, the dyeing process is the core link, and the precise addition of auxiliaries (such as leveling agents, fixing agents, and softeners) is crucial.

[0003] Chinese Patent No. CN217231177U discloses a device for adding auxiliaries for fiber dyeing, including a dyeing barrel. The dyeing barrel is cylindrical, with a rotating hole in the middle of the ground end face of the inner cavity, and a recessed platform on the top of the inner side wall. The driver is located on the top of the left outer wall of the dyeing barrel. A rotating frame is rotatably connected to the inner cavity of the dyeing barrel, and a dyeing thread structure is sleeved on the rotating frame. A rotating top frame is fastened to the top of the rotating frame, and an auxiliary adding structure is provided on the top of the rotating top frame. The auxiliary adding structure includes a conical barrel at the top, and a valve is provided in the pipe at the bottom of the conical barrel.

[0004] Regarding the aforementioned technologies, adding auxiliaries directly into the dyeing tank via a conical drum presents the challenge of precisely controlling the dosage of auxiliaries added to the equipment. Differences in the amount of auxiliaries added can easily lead to inconsistent dyeing depths in the fabric, thus affecting the dyeing quality. Utility Model Content

[0005] In order to add auxiliaries in a quantitative manner and improve the dyeing quality, this application provides an auxiliary agent quantitative addition device for a dyeing machine.

[0006] The auxiliary agent quantitative addition device for a dyeing machine provided in this application adopts the following technical solution: A quantitative addition device for dyeing machine includes a frame and a feeding tank. The feeding tank has a connection port on its periphery. The feeding tank is rotatably connected to the frame. The frame is connected to a rotating component. The rotating component is used to drive the feeding tank to rotate and drive the connection port to communicate with the feeding port of the dyeing tank.

[0007] By adopting the above technical solution, during use, the auxiliary agent is injected into the feeding tank to fill the feeding tank. When the dyeing tank needs to add auxiliary agent, the rotating component drives the feeding tank to rotate around the axis, so that the connection port of the feeding tank is aligned and connected with the feeding port of the dyeing tank, and the auxiliary agent flows into the dyeing tank. The capacity of the feeding tank is fixed, which makes it easy to add auxiliary agent quantitatively into the dyeing tank, minimizes the error of manual addition, and improves the dyeing quality.

[0008] Optionally, a rotating shaft is connected to one end of the feeding hopper. The rotating shaft is rotatably connected to the frame. The rotating assembly includes a first motor, a first gear, and a second gear. The first motor is connected to the frame, the first gear is connected to the output shaft of the first motor, and the second gear is sleeved on the rotating shaft. The first gear and the second gear mesh.

[0009] By adopting the above technical solution, when in use, the first motor starts and drives the first gear to rotate. The first gear meshes and drives the second gear to rotate synchronously with the shaft, thereby driving the feeding barrel to rotate smoothly, so as to facilitate the connection of the feeding port near the dyeing barrel.

[0010] Optionally, a cleaning port is provided at one end of the feeding hopper, and a sealing cover is connected to the feeding hopper. The sealing cover is used to seal the cleaning port and is detachably connected to the frame.

[0011] By adopting the above technical solution, when in use, the sealing cap tightly covers the cleaning port to minimize the leakage of additives from the cleaning port. When it is necessary to clean the residue in the feeding tank, the sealing cap can be removed to clean the residual additives in the tank through the cleaning port, thus facilitating the cleaning of the feeding tank.

[0012] Optionally, the frame has a rotating cavity, the length direction of which is consistent with the length direction of the feeding barrel. The rotating shaft is rotatably connected to the inner wall of one end of the rotating cavity, and the rotating shaft is detachably connected to one end of the feeding barrel. The feeding barrel is rotatably connected inside the rotating cavity, and the feeding barrel is inserted into the frame through the rotating cavity.

[0013] By adopting the above technical solution, the feeding barrel can be horizontally inserted and installed along the rotating cavity, and the rotating shaft and the feeding barrel can be detachably connected, so as to facilitate the replacement of feeding barrels of different volumes and thus adapt to different production needs.

[0014] Optionally, the rotating shaft is connected to a positioning block, and a positioning groove is provided at one end of the feeding barrel. The positioning block is a rectangular block, and the positioning groove is a rectangular groove. The positioning block is inserted into the rotating shaft through the positioning groove.

[0015] By adopting the above technical solution, the positioning block and the positioning groove are precisely inserted during use, which facilitates the synchronous rotation of the rotating shaft and the feeding barrel, and minimizes the deviation of the connection port caused by relative slippage between the two, and shortens the assembly time of the feeding barrel and the rotating shaft.

[0016] Optionally, a first spring is connected to the inner wall of the end of the rotating cavity away from the cleaning port. The length direction of the first spring is consistent with the length direction of the feeding barrel. A push ring is connected to the other end of the first spring. The push ring is in contact with one end of the feeding barrel. The first spring is used to drive the push ring to move and drive the push ring to push the feeding barrel away from the rotating cavity.

[0017] By adopting the above technical solution, when it is necessary to replace the feeding barrel, the sealing cover is removed from the frame, the first spring releases its elastic force, and the pushing ring pushes the feeding barrel towards the cleaning port, so that part of the feeding barrel extends out of the rotating cavity, thereby making it easier for the operator to remove the feeding barrel, further shortening the cleaning and maintenance time and improving the convenience of operation.

[0018] Optionally, the frame is provided with a connecting groove, the length direction of which is consistent with the length direction of the feeding barrel. The sealing cover is connected to a connecting block, which is inserted into the frame through the connecting groove. The connecting block slides along the length direction of the feeding barrel and engages with the inner wall of the connecting groove. The frame is provided with a limiting groove, the length direction of which is consistent with the circumferential direction of the feeding barrel. One end of the limiting groove is connected to the connecting groove, and the connecting block slides along the circumferential direction of the feeding barrel and engages with the inner wall of the limiting groove.

[0019] By adopting the above technical solution, when installing the sealing cover, the connecting block first slides along the length of the feeding barrel and is inserted into the connecting groove. When the connecting block moves and approaches the limiting groove, the sealing cover is rotated so that the sealing cover slides along the circumference of the feeding barrel and fits into the limiting groove, so that the connecting block moves away from the connecting groove. Finally, it is fixed with bolts. The limiting groove can restrict the sealing cover from moving axially along the feeding barrel, and try to avoid the situation where the sealing cover is pushed out by the spring force of the first spring during installation.

[0020] Optionally, a sealing layer is connected to the end of the sealing cap near the feeding barrel, and the sealing layer is in contact with the feeding barrel.

[0021] By adopting the above technical solution, during use, the sealing layer fits tightly against the edge of the cleaning port of the feeding barrel, filling the tiny gap between the sealing cap and the feeding barrel, minimizing leakage of viscous additives from the gaps, and reducing additive waste.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When in use, inject the auxiliary agent into the feeding bucket until it is full. When the dyeing bucket needs to add auxiliary agent, rotate the component to drive the feeding bucket to rotate around the axis, so that the connection port of the feeding bucket is aligned and connected with the feeding port of the dyeing bucket. The auxiliary agent flows into the dyeing bucket. The capacity of the feeding bucket is fixed, which makes it easy to add the auxiliary agent into the dyeing bucket in a quantitative manner, minimizes the error of manual addition, and improves the dyeing quality. 2. When in use, the first motor starts and drives the first gear to rotate. The first gear meshes and drives the second gear to rotate synchronously with the shaft, thereby driving the feeding barrel to rotate smoothly, so as to facilitate the connection of the feeding port near the dyeing barrel. 3. The feeding bucket can be horizontally inserted and installed along the rotating cavity, and the rotating shaft and the feeding bucket can be detachably connected, so as to facilitate the replacement of feeding buckets of different volumes and thus adapt to different production needs.
