Description

Technical Field

[0001] This utility model relates to the field of setting machine technology, and in particular to a setting machine additive dispensing device. Background Technology

[0002] In the textile printing and dyeing industry, the setting machine is a key piece of equipment in the finishing process. Its main function is to enable fabrics to achieve a stable width, smooth appearance, and the required hand feel and functionality after high-temperature treatment. To achieve these effects, various chemical auxiliaries, such as softeners, waterproofing agents, and antistatic agents, need to be applied to the fabric during the setting process. Existing setting machine auxiliary agent dispensing devices typically consist of multiple independent auxiliary agent storage tanks, manual valves, simple flow meters, and a mixing tank. According to the process formula requirements, the operator manually opens and closes the valves, relying on the flow meter reading or experience time, to inject different types of auxiliaries into the mixing tank in proportion. After dilution with water and thorough mixing, the mixture is then supplied to the setting machine's rollers via a delivery pump.

[0003] However, the existing additive dispensing devices for setting machines have significant technical defects. These defects mainly stem from their rudimentary mechanical structure and reliance on manual operation. First, the accuracy of dispensing depends heavily on the experience and responsibility of the operators. Manually controlling the valve opening and timing can easily lead to dispensing errors, resulting in large fluctuations in additive concentration, which directly affects the stability and consistency of product quality. Second, the entire dispensing process has a low degree of automation, is cumbersome to operate, has high labor intensity, and makes it difficult to improve production efficiency.

[0004] To address the above problems, it is necessary to design a stenter additive dispensing device to overcome these issues. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-4 As shown, a stenter additive dispensing device includes a frame 1, a protective box 2 is fixedly installed in the middle of the frame 1, and a dispensing component 3 is provided on the upper side of the protective box 2.

[0027] The batching assembly 3 includes a motor 310 fixedly installed inside the protective box 2. The output end of the motor 310 is fixedly connected to a support column 309 via a coupling. A cylinder 302 is fixedly installed at one end of the support column 309. A cover plate 301 is fixedly installed on the top of the cylinder 302. A storage tube 311 is fixedly installed around the inside of the cylinder 302.

[0028] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3As shown, a storage tube top cover 312 is fixedly installed on the top of the storage tube 311, a connecting tube 313 is fixedly installed on one lower end of the storage tube 311, and a solenoid valve 314 is fixedly installed on one end of the connecting tube 313. Mixing tubes 306 are fixedly arranged around the outer wall of the cylinder 302. The storage tube 311 and the diversion tube 303 are connected through the connecting tube 313. A guide tube 304 is fixedly installed at the lower end of the diversion tube 303, and the mixing tube 306 is fixedly connected to the lower end of the guide tube 304. A support is fixedly installed on the outside of the mixing tube 306. A branch pipe 308 is fixedly installed on one side of the mixing pipe 306, and a drain pipe 307 is fixedly installed on one end of the mixing pipe 306. A feeding pipe 315 is fixedly installed on one side of the protective box 2, and a discharge pipe 316 is fixedly installed on one end of the feeding pipe 315. A stirring motor 318 is fixedly installed at the bottom of the feeding pipe 315. A stirring rod 321 is fixedly connected to the output end of the stirring motor 318 through a coupling. A stirring blade 317 is fixedly connected to the outer wall of the stirring rod 321. The stirring rod 321 and the stirring blade 317 are located inside the feeding pipe 315.

[0029] Among them, the connecting pipe 313, the feeding pipe 316, and the drain pipe 307 are all equipped with solenoid valves 314 to facilitate control of the feeding amount;

[0030] Among them, the storage tube 311 adopts a ring array layout, such as 6 tubes evenly distributed on the inner wall of the cylinder 302. Each tube independently stores different additives such as softener, antistatic agent, and flame retardant. The top cover 312 of the storage tube is designed with a quick-release sealing structure to support rapid feeding and cleaning. The connecting tube 313 is made of corrosion-resistant PTFE material with a smooth inner wall to reduce residue. The solenoid valve 314 is a high-frequency response type with a response time of ≤0.1s, supporting millisecond-level start and stop control. Multiple groups of additives are stored in isolation to avoid chemical reactions or precipitation caused by premixing of additives. The independent pipeline design of the guide tube 304 and the diversion tube 303 prevents additive residues from mixing into other pipelines and prevents cross-contamination.

[0031] Among them, the cylinder 302 is rigidly connected to the support column 309 through a high-strength flange, and the support column has a built-in angular contact bearing to bear the radial load; the motor 310 is a servo motor with an integrated high-precision encoder to realize closed-loop control of the cylinder rotation angle, such as a 60° step positioning error ≤ ±0.5°, ensuring that the outlet of the storage tube 311 and the inlet of the diversion tube 303 are strictly aligned to avoid leakage. The 60° step rotation can complete the switching of the auxiliary agent type within 0.5s, which can adapt to the production needs of multiple formulations.

[0032] Among them, the guide tube 304 adopts a spiral inner wall lead angle of 15° to make the additive form a swirling flow; the mixing tube 306 has built-in static turbulence plates arranged in a staggered 45° pattern to increase the turbulence intensity;

[0033] Among them, the protective box 2 adopts a fully enclosed structure of 304 stainless steel, and the inner wall is lined with flame-retardant and sound-insulating cotton; the bottom of the feeding pipe 315 is equipped with a liquid level sensor to monitor the mixed liquid level in real time; the end of the discharge pipe 316 is equipped with a quick-install clamp interface, which is compatible with the feeding pipes of different diameter shaping machines.

[0034] The working process of this utility model is as follows: Using the stenter additive dispensing device designed in this scheme, during operation, by opening the cover plate 301, and then opening the top covers 312 of the storage tubes 311 arranged around the cylinder 302, the additives are added to the storage tubes 311 respectively. The corresponding storage tube top covers 312 are then closed, and labels with the corresponding names are affixed to the corresponding storage tube top covers 312 for easy addition of additives and to prevent confusion. The frame 1 is then installed on the stenter. The feeding pipe 316 at the lower end of the feeding pipe 315 corresponds to the supply box of the setting machine. When feeding is needed, the motor 310 is controlled by an external controller to work. The motor 310 drives the support column 309 to rotate, and the support column 309 drives the cylinder 302 to rotate. The cylinder 302 rotates 60 degrees in one rotation, which causes the drain pipe 307 to rotate to the upper end of the corresponding feeding pipe 315. The solenoid valve 314 set in the connecting pipe 313 between the storage pipe 311 and the diversion pipe 303 is opened by the external controller, which allows the corresponding... The ingredients inside the storage pipe 311 are discharged into the corresponding distribution pipe 303, then into the guide pipe 304, then into the mixing pipe 306, and finally into the drain pipe 307. The solenoid valve in the drain pipe 307 opens, discharging the ingredients into the ingredient pipe 315. Simultaneously, an external controller controls the rotation of the stirring motor 318 installed at the bottom of the ingredient pipe 315. The stirring motor 318 drives the stirring rod 321 inside the ingredient pipe 315 to rotate. 21 drives the stirring blade 317 to rotate, thereby agitating the ingredients inside the dispensing pipe 315. The motor 310 continues to rotate, driving the diversion pipe 303 on the outer wall of the cylinder 302 to rotate. Different storage pipes 311 can be replaced to discharge the ingredients quantitatively into the dispensing pipe 315. The mixture is quickly mixed by agitation. A liquid level sensor is installed at the bottom of the dispensing pipe 315 to monitor the mixed liquid level in real time, which facilitates the quantitative dispensing of additives and prevents the waste of ingredients caused by manual addition, which cannot control the amount.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
