Description
Technical Field
[0001] This invention relates to the field of textile dyeing and finishing solution preparation technology, and in particular to a syringe-type solution preparation device. Background Technology
[0002] Existing syringe-type solution preparation devices typically use the following methods to complete solution preparation:
[0003] Taking the Chinese patent CN215713991U dual-purpose liquid and powder mixing machine as an example, the robotic arm pulls the squeezing rod of the syringe-type dropper from the mother liquor bottle to complete the material suction. The robotic arm moves the syringe-type dropper as a whole to the target mixing bottle, and the robotic arm squeezes the squeezing rod downwards, so that the liquid in the syringe flows into the mixing bottle from the dropping needle (dropping nozzle). The mother liquor bottle is generally not considered to have a small volume. Because it is necessary to consider that the dropping needle (dropping nozzle) can draw liquid from the mother liquor bottle, it is necessary to ensure that the length of the dropping needle can cover the liquid surface of the mother liquor bottle. Moreover, it is necessary to consider that the dropping needle can draw liquid from the bottom of the mother liquor bottle. Therefore, the length of the dropping needle is almost the same as the height of the mother liquor bottle.
[0004] Regardless of the length of the dripping needle, it is necessary to ensure that the dripping needle (drip tip) penetrates below the liquid surface. Therefore, after aspiration, there will always be liquid residue on the outer wall of the dripping needle (drip tip). During the process of moving the syringe-type dripper to the target solution bottle, the residual liquid on the outer wall of the dripping needle will drip down onto the dripping machine, causing contamination. Furthermore, when dripping the solution to the target solution bottle according to the target value, the residual liquid on the outer wall of the dripping needle will also drip into the solution bottle, resulting in a deviation in the dripping volume (exceeding the set dripping target value) and causing distortion of the solution ratio. The longer the dripping needle, the greater the degree of distortion.
[0005] Taking Chinese patent CN1475299A, an automatic liquid dispensing device, as an example, the sealed container is driven by a squeezing rod (syringe-type liquid dispenser). This sealed container is connected to a mother liquor storage container (mother liquor bottle) and a dispensing receiving container (dispensing bottle) via pipes, and both pipes are equipped with solenoid valves. Controlling the squeezing rod's suction and the solenoid valves' opening and closing completes the replenishment and dispensing of the syringe-type liquid dispenser. The components used in this solution are: pipes are generally metal, plastic, or flexible rubber pipes; the solenoid valve structure is generally a metal channel and a sealing valve. However, dyeing and finishing solutions often involve corrosive chemical liquids. Repeated flow of the liquid through these components will cause corrosion. Even regular cleaning of these components during use cannot completely solve the corrosion problem. When these components corrode, the liquid in the mother liquor affects the quality of the liquid during transport through the corroded components, thus compromising the quality of the liquid dispensing. Summary of the Invention
[0006] The purpose of this invention is to provide a syringe-type liquid preparation device to overcome the shortcomings of the prior art.
[0007] The above-mentioned objectives of the present invention are achieved by the following technical means:
[0008] A syringe-type liquid preparation device includes a mother liquor bottle 1 and a syringe-type liquid preparation device 2. The mother liquor bottle 1 is provided with a bottle cap 3, the bottle cap 3 is provided with a plug-in seat 4, and the plug-in seat 4 is provided with a cone position 41.
[0009] The syringe-type liquid dispensing device 2 is provided with a guide cone 5 and a dropper 6 extending out of the guide cone 5;
[0010] The mother liquor bottle 1 is also provided with a liquid tube 7, which is connected to the plug-in seat 4 and communicates with the cone position 41.
[0011] When the guide cone 5 of the syringe-type liquid dispenser 2 is inserted into the cone position 41 of the connector 4 and presses against the connector 4, the dropper 6 and the liquid tube 7 are connected to form an inlet pipe, and the part where the guide cone 5 and the cone position 41 are in contact forms a sealing layer A.
[0012] Furthermore, a spring 91 is provided between the bottle cap 3 and the plug 4, and a spring gap 92 is formed between the bottle cap 3 and the plug 4 under the cooperation of the spring 91;
[0013] When the guide cone 5 of the syringe-type liquid dispenser 2 is inserted into the cone position 41 of the connector 4, if the syringe-type liquid dispenser 2 deviates from the central axis of the cone position 41, during the process of inserting the guide cone 5 into the cone position 41, the spring 91 adaptively adjusts the spring spacing 92 so that the connector 4 tilts moderately in the direction of deviation to assist the guide cone 5 in properly inserting into the cone position 41.
[0014] Optionally, the plug-in seat 4 is a rigid seat made of plastic or metal material, and the inner wall of the cone 41 has one or more first grooves 42. The first groove 42 is provided with a first sealing ring 43. The part of the guide cone 5 that contacts the first groove 42 forms the sealing layer A.
[0015] Optionally, the insertion seat 4 is an elastic seat made of rubber. When the guide cone 5 is inserted into the cone position 41 and presses against the elastic seat, the elastic seat adaptively adjusts the depth of the cone position 41 downward after being subjected to force. At the same time, the inner diameter of the cone position 41 narrows from top to bottom until a part of its inner wall is in complete and tight contact with the guide cone 5 to form the sealing layer A.
[0016] Preferably, both the bottle cap 3 and the connector 4 are provided with two or more corresponding connecting holes 8. The corresponding connecting holes 8 are used to connect the bottle cap 3 and the connector 4 with bolts 9. The bolts 9 include the spring 91 provided between the bottle cap 3 and the connector 4.
[0017] Preferably, one end of the spring 91 is sleeved on the upper edge of the cone 41; or the bottle cap 3 has a positioning groove on its surface, and one end of the spring 91 is located in the positioning groove.
[0018] Preferably, the cone 41 has a leak 44, and the liquid pipe 7 is screwed to the leak 44.
[0019] Preferably, the syringe-type liquid dispenser 2 further includes a liquid dispensing syringe 21, which is composed of a syringe 211, a squeezing rod 212, and the dropper 6;
[0020] The guide cone 5 has a syringe hole 51 at the top and a dropper hole 52 at the bottom that communicates with the syringe hole 51.
[0021] The syringe 211 is screwed to the syringe hole 51, and the dropper 6 extends from the dropper hole 52 out of the guide cone 5.
[0022] Preferably, the inner wall of the syringe hole 51 is provided with a second groove 511, and the second groove 511 is provided with a second sealing ring 512.
[0023] Preferably, the guide cone 5 is further provided with a cone edge 53;
[0024] When the guide cone 5 is inserted into the cone position 41 of the connector 4, the cone edge 53 restricts the guide cone 5 from being inserted further into the cone position 41, preventing the guide cone 5 from damaging the first sealing ring 43 and the auxiliary guide cone 5 from being properly inserted into the cone position 41.
[0025] The beneficial effects of adopting the above technical solution are as follows:
[0026] In this invention, during the process of moving the syringe-type dispensing device to the target dispensing bottle after liquid aspiration (extraction), no residual liquid drips onto the machine or into the target dispensing bottle from the outer wall of the dropper, ensuring accurate dripping target values. Furthermore, the process of transporting the liquid from the mother liquor bottle to the target dispensing bottle does not use easily corroded intermediate pipes or control valves, maintaining the quality of the original liquid and ensuring accurate dispensing.

Detailed Implementation
[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0038] Example 1. Figure 1-11 A syringe-type liquid preparation device is shown, including a mother liquor bottle 1 and a syringe-type liquid preparation device 2. The mother liquor bottle 1 is provided with a bottle cap 3, the bottle cap 3 is provided with a plug-in seat 4, and the plug-in seat 4 is provided with a cone position 41.
[0039] The syringe-type liquid dispensing device 2 is provided with a guide cone 5 and a dropper 6 extending out of the guide cone 5;
[0040] The mother liquor bottle 1 is also provided with a liquid tube 7, which is connected to the plug-in seat 4 and communicates with the cone position 41.
[0041] When the guide cone 5 of the syringe-type liquid dispenser 2 is inserted into the cone position 41 of the connector 4 and presses against the connector 4, the dropper 6 and the liquid tube 7 are connected to form an inlet pipe, and the part where the guide cone 5 and the cone position 41 are in contact forms a sealing layer A.
[0042] Working principle: such as Figure 4-6 or Figure 9-11 As shown, when the guide cone 5 of the syringe-type liquid dispenser 2 is inserted into the cone position 41 of the plug-in seat 4 and presses against the plug-in seat 4, at the same time the dropper 6 is inserted into the liquid tube 7; the part where the guide cone 5 and the cone position 41 come into contact forms a sealing layer A to prevent external air from entering the mother liquor bottle; the gap below the sealing layer A, the gap between the dropper 6 and the liquid tube 7, the liquid tube 7 and the space inside the mother liquor bottle 1 together form a gas channel that becomes a temporary sealed space; when the syringe-type liquid dispenser 2 performs a liquid drawing action (vacuuming) and generates negative pressure, the liquid in the mother liquor bottle enters the syringe-type liquid dispenser 2 through the liquid tube 7 and the dropper 6 to complete the liquid aspiration.
[0043] like Figure 6 or Figure 11 As shown, since the gas channel is sealed, when the syringe-type liquid dispenser 2 is evacuated to generate negative pressure, the liquid in the mother liquor bottle enters the liquid tube 7 and reaches the end face of the dropper 6. The gravity balance of the liquid in the liquid tube 7 is affected by the vacuum negative pressure above the end face of the dropper 6. The mother liquor enters the dropper 6 in an intermittent liquid state. The liquid level in the liquid tube 7 continuously switches between reaching the end face of the dropper 6 and being below the end face of the dropper 6 until the negative pressure is insufficient to draw up the mother liquor.
[0044] like Figure 6 or Figure 11 As shown, multiple uniform-speed vacuuming experiments were conducted on the syringe-type dispensing device 2. Please refer to the test record table below. We used a stepper motor to drive the squeezing rod to perform vacuuming of the syringe 10 times. Each time, the stepper motor drive speed was 30 mm / s, and the acceleration time was 1-5 seconds twice. During the process of the liquid in the mother liquor bottle entering the syringe-type dispensing device, the liquid submerged the end face of the dropper 6 by a maximum of 0.14 mm. Considering that the dropper length is at least 10 mm, the liquid on its outer wall accounts for about 1.4% of the total length of the dropper 6. The residual liquid on the outer wall of the dropper is almost negligible. Therefore, in this invention, during the process of moving to and dripping the liquid onto the target dispensing bottle after liquid extraction, there is no residual liquid on the outer wall of the dropper 6, which does not contaminate the machine and improves the accuracy of the dispensing ratio.
[0045]
[0046] Furthermore, in this invention, the liquid is transported from the mother liquor bottle to the target dispensing bottle without using easily corroded intermediate pipes and control valves, thus maintaining the quality of the liquid in the mother liquor bottle and ensuring accurate dispensing.
[0047] Example 2. This example is based on Example 1, such as... Figure 4 or Figure 10 As shown, a spring 91 is provided between the bottle cap 3 and the plug 4, and a spring gap 92 is formed between the bottle cap 3 and the plug 4 under the cooperation of the spring 91;
[0048] When the guide cone 5 of the syringe-type liquid dispenser 2 is inserted into the cone position 41 of the connector 4, if the syringe-type liquid dispenser 2 deviates from the central axis of the cone position 41, during the process of inserting the guide cone 5 into the cone position 41, the spring 91 adaptively adjusts the spring spacing 92 so that the connector 4 tilts moderately in the direction of deviation to assist the guide cone 5 in properly inserting into the cone position 41.
[0049] Example 3. This example illustrates a first liquid preparation device. This example is based on Example 2, as follows: Figure 1-6 As shown, the plug-in seat 4 is a rigid seat made of plastic or metal material. The inner wall of the cone position 41 has one or more first grooves 42. The first groove 42 is provided with a first sealing ring 43. The part of the guide cone 5 that contacts the first groove 42 forms the sealing layer A.
[0050] When the guide cone 5 of the syringe-type dispensing device 2 is inserted into the cone position 41 of the connector 4 and presses against the connector 4, the dropper 6 is inserted into the liquid tube 7 at the same time; the part of the guide cone 5 that is in close contact with the first sealing ring 43 forms a sealing layer A to prevent external air from entering the mother liquor bottle.
[0051] Example 4. This example illustrates a second liquid preparation device. This example is based on Example 2, such as... Figure 7-11 As shown, the insertion seat 4 is an elastic seat made of rubber. When the guide cone 5 is inserted into the cone position 41 and presses against the elastic seat, the elastic seat adaptively adjusts the depth of the cone position 41 downward after being subjected to force. At the same time, the inner diameter of the cone position 41 narrows from top to bottom until a part of its inner wall is in complete and tight contact with the guide cone 5 to form the sealing layer A.
[0052] In this embodiment, the guide cone 5 and the elastic seat 4 operate in conjunction. The elastic seat 4 serves as both the insertion seat for the guide cone 5 and does not require an additional sealing ring as a temporary seal.
[0053] Furthermore, since the elastic seat 4 is different from the single-ring sealing characteristic of the sealing ring, the entire elastic seat 4 is used for the sealing needs of this invention. It is made of rubber material and can be used for sealing. It has its own tensile recovery elasticity. When the guide cone 5 is frequently associated with it, it will wear out the elastic seat 4 when it is pressed and sealed. Because it is shaped like a cone seat as a whole, compared with a single type of sealing ring, this elastic seat 4 is more durable.
[0054] For example, such as Figure 4 or Figure 10 As shown, the bottle cap 3 is a wide-mouth cap, and the bottle cap 3 is detachably threaded to the mother liquor bottle 1. The cap can be removed to replenish the mother liquor bottle, allowing for reuse of the mother liquor bottle.
[0055] For example, based on embodiment 3, such as Figure 1-6As shown, both the bottle cap 3 and the plug-in seat 4 are provided with two or more corresponding connecting holes 8. The corresponding connecting holes 8 are used to connect the bottle cap 3 and the plug-in seat 4 with bolts 9. The bolts 9 include the spring 91 provided between the bottle cap 3 and the plug-in seat 4.
[0056] For example, a bolt consists of a screw with a nut and a bolt. The screw passes through the bottle cap and the connector, and the nut locks the screw to complete the connection between the bottle cap and the connector. Alternatively, the screw can pass through the connector and the bottle cap, and the nut locks the screw to complete the connection between the bottle cap and the connector.
[0057] For example, such as Figure 1-6 As shown, one end of the spring 91 is sleeved on the upper edge of the cone 41; or the bottle cap 3 has a positioning groove (not shown in the figure) on its surface, and one end of the spring 91 is located in the positioning groove.
[0058] For example, such as Figure 1-11 As shown, the cone 41 has a leak 44, and the liquid pipe 7 is screwed to the leak 44.
[0059] For example, such as Figure 1-11 As shown, the syringe-type liquid dispenser 2 also includes a liquid dispensing syringe 21, which is composed of a syringe 211, a squeezing rod 212 and the dropper 6;
[0060] The guide cone 5 has a syringe hole 51 at the top and a dropper hole 52 at the bottom that communicates with the syringe hole 51.
[0061] The syringe 211 is screwed to the syringe hole 51, and the dropper 6 extends from the dropper hole 52 out of the guide cone 5.
[0062] For example, such as Figure 5 or Figure 10 As shown, the inner wall of the syringe hole 51 is provided with a second groove 511, and the second groove 511 is provided with a second sealing ring 512.
[0063] For example, such as Figure 1-11 As shown, the guide cone 5 is also provided with a cone edge 53;
[0064] When the guide cone 5 is inserted into the cone position 41 of the connector 4, the cone edge 53 restricts the guide cone 5 from being inserted further into the cone position 41, preventing the guide cone 5 from damaging the first sealing ring 43 and the auxiliary guide cone 5 from being properly inserted into the cone position 41.
