Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a liquid preparation instrument with steel balls. Background Technology

[0002] According to the national standard GB / T3921-2008, "Test for color fastness of textiles and test for color fastness to soap washing", the fabric cut according to the requirements must be weighed using a test balance, and soap solution must be prepared according to the proportions specified in the standard. Then, an appropriate amount of steel balls must be added according to the standard.

[0003] The existing technology involves manual mixing throughout the entire experimental process, which is slow, has a high error rate, and results in inaccurate soap solution addition. It also requires manual addition of steel balls, manual data recording, and the inability to perform real-time measurements during mass production, necessitating a large amount of manpower for collaborative experiments.

[0004] Furthermore, existing technologies often use direct electronic scales to weigh soap solution, but the scales are inaccurate because the soap solution has an impact when it flows down. Calculating the volume of soap solution by pumping it through a pump is also inaccurate due to air bubbles in the soap solution. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention provides a steel ball-loaded dispensing apparatus. The top of the dispensing housing has several inlets, each connected to a liquid feeding system. Different components of soap solution are poured into each inlet. The liquid feeding system is installed on the dispensing housing and pumps the soap solution of different components into a vacuum discharge system. The vacuum discharge system is also installed on the dispensing housing and at the end of the liquid feeding system, enabling continuous degassing and precise output of the soap solution. A steel ball injection system is installed on the dispensing housing. Both the steel ball injection system and the vacuum discharge system are installed above the weighing system. The vacuum discharge system, from top to bottom, includes a degassing transfer device, a vacuum device, and a pumping device. The lower side of the degassing transfer device is located inside the vacuum device. The degassing transfer device, vacuum device, and pumping device are sealed together. The vacuum device generates a vacuum effect to degas the soap solution. The degassing transfer device sends the soap solution flowing in from the inlets into the vacuum device for degassing. The pumping device precisely outputs the degassed soap solution. The steel ball injection system is used to inject steel balls.

[0016] The defoaming transfer device includes a defoaming transfer roller, a defoaming upper plate, two defoaming middle plates, a defoaming bottom plate, and a defoaming scraper roller. The two defoaming middle plates are installed between the upper and lower plates, clamping the two sides of the defoaming transfer roller and separating its upper and lower sides. The defoaming transfer roller is rotatably mounted between the upper and lower plates. Several defoaming separator plates are provided on the upper side of the two middle plates, each separator plate being sealed to the two middle plates. Each separator plate has a sealing ring adjacent to the defoaming transfer roller.

The inlet is connected to the storage space. The defoaming transfer roller is equipped with several defoaming rings. When the defoaming rings rotate, soap solution adheres to them. The rotation of the defoaming rings carries the soap solution to the vacuum device under the defoaming plate. The bubbles in the soap solution expand and burst, thus achieving defoaming. The gap between the defoaming rings and the defoaming plate is between 0.1 mm and 0.3 mm. Because the soap solution fills the space between the defoaming rings and the defoaming plate, the vacuum degree under the defoaming rings and the defoaming plate is maintained, and the soap solution can pass through the space between the defoaming rings and the defoaming plate. The defoaming scraper roller is rotatably mounted on the defoaming base plate. The defoaming scraper roller is equipped with a defoaming scraper plate that is adapted to each defoaming ring to scrape off the soap solution on the defoaming rings. Attached Figure Description

[0041] The following is combined Figures 1-10 The present invention describes a steel ball-loaded liquid preparation apparatus.

[0042] This invention provides a dispensing apparatus with steel balls, comprising a dispensing housing 1, a liquid feeding system 2, a vacuum dispensing system 3, a steel ball injection system 4, and a weighing system 5. The top of the dispensing housing 1 has several liquid inlets 21, each connected to the liquid feeding system 2. Different components of soap solution are poured into each inlet 21. The liquid feeding system 2 is installed on the dispensing housing 1 to pump soap solutions of different components into the vacuum dispensing system 3. The vacuum dispensing system 3 is installed on the dispensing housing 1 and at the end of the liquid feeding system 2, achieving continuous degassing and precise output of the soap solution. The steel ball injection system 4 is installed on the dispensing housing 1. On the liquid housing 1, the steel ball injection system 4 and the vacuum discharge system 3 are both installed on the upper side of the weighing system 5. The vacuum discharge system 3 includes, from top to bottom, a defoaming transfer device 31, a vacuum device 32, and a pumping device 33. The lower side of the defoaming transfer device 31 is located inside the vacuum device 32. The defoaming transfer device 31, the vacuum device 32, and the pumping device 33 are sealed together. The vacuum device 32 is used to generate a vacuum effect to remove air bubbles. The defoaming transfer device 31 sends the soap liquid flowing in from the liquid inlet 21 into the vacuum device 32 to remove air bubbles. The pumping device 33 accurately outputs the soap liquid after defoaming. The steel ball injection system 4 is used to inject steel balls.

[0043] Specifically, each liquid inlet 21 is hinged with a liquid inlet cover to prevent soap liquid contamination.

[0044] Specifically, the liquid feeding system 2 includes several inlet pipes 22, several liquid pumps 23 and several liquid injection pipes 24. The inlet pipes 22 and the liquid injection pipes 24 are all installed on the liquid pumps 23. Each inlet pipe 22 is connected to the corresponding inlet port 21, and each liquid injection pipe 24 is connected to the corresponding vacuum discharge system 3. The liquid pumps 23 pump the soap solution into the vacuum discharge system 3.

[0045] Specifically, the steel ball feeding system 4 includes a steel ball inlet, a steel ball intermittent feeder, and a feed outlet 41. The steel ball intermittent feeder is a commercially available technology and will not be described in detail here. The steel ball inlet is located at the top of the liquid preparation machine housing 1. A steel ball cover plate is hinged on the steel ball inlet to prevent steel ball contamination. The steel ball inlet is connected to the steel ball intermittent feeder, and the feed outlet 41 is connected to the steel ball intermittent feeder to realize the counting output of steel balls.

[0046] Specifically, the weighing system 5 includes several electronic scales to weigh the fabric to be tested, thereby controlling the output of soap solution and steel balls. The fabric to be tested is placed in a standard stainless steel cup. After the electronic scale weighs the total weight of the standard stainless steel cup and the fabric, it transmits an electrical signal to the PLC controller, which then transmits the signal to the vacuum discharge system 3 to achieve accurate discharge. The PLC controller is preferably an FX3U series controller.

[0047] Specifically, the defoaming transfer device 31 includes a defoaming transfer roller 311, a defoaming upper plate 312, two defoaming middle plates 313, a defoaming bottom plate 314, and a defoaming scraper roller 315. The two defoaming middle plates 313 are installed between the defoaming upper plate 312 and the defoaming bottom plate 314, clamping both sides of the defoaming transfer roller 311, thereby separating the upper and lower sides of the defoaming transfer roller 311. The defoaming transfer roller 311 is rotatably mounted. Between the upper defoaming plate 312 and the lower defoaming plate 314, several defoaming separator plates 316 are provided on the upper side of the two middle defoaming plates 313. Each defoaming separator plate 316 is sealed to the two middle defoaming plates 313. Each defoaming separator plate 316 is provided with a sealing ring at the position adjacent to the defoaming transfer roller 311. The adjacent defoaming separator plates 316, together with the middle defoaming plates 313 and the defoaming transfer roller 311, form a defoaming storage space to separate various soap solutions. The liquid outlet 21 is connected to the storage space. The defoaming transfer roller 311 is equipped with several defoaming rings 3111. When the defoaming rings 3111 rotate, soap solution adheres to them. The rotation of the defoaming rings 3111 carries the soap solution to the vacuum device 32 below the defoaming plate 313. The bubbles in the soap solution expand and burst, achieving defoaming. The gap between the defoaming rings 3111 and the defoaming plate 313 is between 0.1 mm and 0.3 mm. Because the soap... The liquid filling between the defoaming ring 3111 and the defoaming middle plate 313 maintains the vacuum degree under the defoaming ring 3111 and the defoaming middle plate 313, and also allows the soap liquid to pass between the defoaming ring 3111 and the defoaming middle plate 313. The defoaming scraper roller 315 is rotatably mounted on the defoaming base plate 314. The defoaming scraper roller 315 is provided with a defoaming scraper plate 3151 adapted to each defoaming ring 3111 to scrape the soap liquid off the defoaming ring 3111.

[0048] Specifically, the vacuum device 32 includes a vacuum frame 321, with the upper and lower sides of the vacuum frame 321 being sealed and installed with the defoaming transfer device 31 and the pumping device 33, respectively. A vacuum tube 322 is connected to the vacuum frame 321, thereby achieving a vacuum.

[0049] Specifically, the pumping device 33 includes a pumping transfer roller 331, a pumping upper plate 332, two pumping middle plates 333, a pumping bottom plate 334, and a pumping scraper roller 335. The two pumping middle plates 333 are installed between the pumping upper plate 332 and the pumping bottom plate 334, clamping both sides of the pumping transfer roller 331, thereby separating the upper and lower sides of the pumping transfer roller 331. The pumping transfer roller 331 is rotatably mounted on the pumping upper plate 332 and the pumping bottom plate 335. Between the plates 334, several pumping baffles 336 are provided on the upper side of the two pumping intermediate plates 333. Each pumping baffle 336 is sealed to the two pumping intermediate plates 333. Each pumping baffle 336 is provided with a sealing ring at the position adjacent to the pumping transfer roller 331. The adjacent pumping baffles 336, together with the pumping intermediate plates 333 and the pumping transfer roller 331, form a pumping storage space to separate various soap solutions. Several pumping rings 3311 are provided on the pumping transfer roller 331. When pumping ring 3311 rotates, soap solution adheres to it. The rotation of pumping ring 3311 carries the soap solution to the underside of pumping plate 333, thus achieving pumping. The gap between pumping ring 3311 and pumping plate 333 is between 0.1 mm and 0.3 mm. Because the soap solution fills the space between pumping ring 3311 and pumping plate 333, a vacuum is maintained between the upper side of pumping ring 3311 and pumping plate 333, allowing the soap solution to flow from the pumping ring 3311 and pumping plate 333. The pumping scraper roller 335 is rotatably mounted on the pumping base plate 334 and passes between the plates 333. The pumping scraper roller 335 is equipped with a pumping scraper plate 3351 that is adapted to each pumping ring 3311 to scrape the soap liquid off the pumping ring 3311. A pumping pipe 3352 is installed on the lower side of each pumping scraper plate 3351. Preferably, the upper side of the pumping pipe 3352 is funnel-shaped to facilitate the soap liquid to fall. A peristaltic pump is installed on each pumping pipe 3352 to accurately pump out the defoamed soap liquid.

[0050] To facilitate scraping control, the defoaming transfer roller 311, the defoaming scraping roller 315, the pumping transfer roller 331, and the pumping scraping roller 335 are all driven by servo motors. Each servo motor is electrically connected to a PLC controller. Due to the precise pumping of the peristaltic pump, the time it takes for the defoaming scraping roller 315 to rotate the defoaming scraping plate 3151 to fit against the defoaming transfer roller 311, and the time it takes for the pumping scraping roller 335 to rotate the pumping scraping plate 3351 to fit against the pumping transfer roller 331 are all controlled. The time only needs to be roughly controlled. Based on the rotational linear speed of the defoaming transfer roller 311 and the pumping transfer roller 331, as well as the thickness of the soap solution, the mass of soap solution carried out by the pumping ring 3311 and the defoaming ring 3111 per unit time is calculated. The product of the soap solution thickness and the area of ​​the pumping scraper 3351 sweeping the pumping ring 3311 is the volume of soap solution scraped off. The mass of soap solution scraped off by the defoaming scraper 3151 is calculated using the same method, and the mass of soap solution is easy to obtain, so it will not be elaborated here.

[0051] In a preferred embodiment, in order to independently control the rotation of each defoaming scraper 3151 and each pumping scraper 3351, each defoaming scraper 3151 is rotatably mounted on the defoaming scraper roller 315 via a defoaming scraper rotating sleeve 3152. The defoaming scraper rotating sleeve 3152 is mounted on the defoaming scraper roller 315 via bearings. Each defoaming scraper rotating sleeve 3152 has a scraping control plate 3153. Electromagnets are provided on both the upper and lower sides of each scraping control plate 3153 to realize the scraping of the defoaming scraper 3151.

[0052] Each pumping scraper 3351 is rotatably mounted on the pumping scraper roller 335 via a pumping scraper rotating sleeve 3353. The pumping scraper rotating sleeve 3353 is mounted on the pumping scraper roller 335 via bearings. Each pumping scraper rotating sleeve 3353 has a pumping control plate 3354. Electromagnets are provided on both the upper and lower sides of each pumping control plate 3354 to realize the scraping of material by the pumping scraper 3351.

The vacuum level of the pumping plate (333) and the upper side of the pumping middle plate (333) are such that the pumping scraper roller (335) is rotatably mounted on the pumping base plate (334), the pumping scraper roller (335) is provided with a pumping scraper plate (3351) adapted to each pumping ring (3311), a pumping pipe (3352) is installed on the lower side of each pumping scraper plate (3351), and a peristaltic pump is installed on each pumping pipe (3352).
