Description

Technical Field

[0001] This invention relates to the field of ingredient preparation, specifically to an automated ingredient preparation station system and its ingredient preparation method. Background Technology

[0002] In many industrial production processes, mixing two or more powders is often involved. For example, in the production of bathtubs, unsaturated polyester resin, heavy calcium carbonate (inorganic filler), and cobalt naphthenate (accelerator) need to be mixed in specific proportions. Currently, automated batching stations are typically used for this powder mixing operation.

[0003] In traditional automated batching station systems, when mixing multiple materials, all materials are added to the mixing tank before mixing begins. At this point, the amount of material is large, and the material may accumulate at the bottom or edge of the tank. The lower and upper layers of material are not mixed to varying degrees, resulting in uneven overall mixing and causing uneven composition of the final batch.

[0004] The currently disclosed Chinese patent CN216334301 U discloses a batching system with an automatically adjustable capacity storage tank, including a mixing tank. A fixed frame is provided at the upper end of the mixing tank, and a storage tank is disposed inside the fixed frame. A reinforced edge is provided at the lower end of the storage tank, and a rotating plate is provided at the lower end of the reinforced edge. A connecting shaft is provided at one end of the rotating plate, and a switch cylinder is provided at the upper end of the connecting shaft. A load-bearing plate is provided inside the fixed frame, and a mounting base is provided inside the load-bearing plate. A force sensor is provided at the upper end of the mounting base, and a connecting wire is provided at one end of the mounting base. A main auger is provided inside the mixing tank, and a polygonal tamping plate is provided on the side wall of the main auger. A protective shaft is provided at the upper end of the main auger.

[0005] According to the aforementioned patent, the patent senses the storage capacity inside the storage tank and transmits a signal to the switch drum, causing it to rotate and automatically rotate the plate, thus allowing the material inside the storage tank to flow out, thereby achieving the purpose of controlling the output and storage capacity. However, the stirring rod in this patent still cannot stir the material at the bottom of the tank, and there is still a situation where the material accumulates at the bottom of the tank, resulting in uneven mixing of the material. Therefore, there is currently a need for a mixing structure that can premix at the inlet. Summary of the Invention

[0006] To address the problems existing in the current technology, this invention provides an automated batching station system. The invention achieves quantitative release of ingredients after a period of mixing by intermittently opening and closing the material discharge channel, thus achieving a preliminary pre-mixing effect. This allows the ingredients to be initially mixed in the upper mixing chamber, and then the intermittent transfer and further mixing of the ingredients from the upper mixing chamber to the lower mixing chamber is achieved by controlling the reciprocating movement of the plug. This avoids the problem of uneven mixing caused by a one-time dumping of ingredients, making the mixing process more thorough and uniform.

[0007] To address the problems of existing technologies, this invention provides an automated batching station system, including a storage unit, a feeding unit, a weighing unit, and a mixing tank. The mixing tank has an internal partition that divides the internal space into an upper mixing chamber and a lower mixing chamber. The partition has a through sleeve that extends downward and connects the upper and lower mixing chambers. A plug that can move along the axis of the through sleeve is provided inside the through sleeve. The plug has an upper stop position and a lower stop position in the axis direction. When the plug is in the upper stop position, the upper peripheral wall of the plug is tightly fitted with the upper edge of the through sleeve. When the plug moves from the upper stop position to the lower stop position, a material discharge channel is formed between the peripheral wall of the plug and the inner wall of the through sleeve. When the plug is in the lower stop position, the material discharge channel is at its maximum opening. The lower end of the through sleeve has a discharge port that communicates with the material discharge channel.

[0008] Preferably, the mixing tank is provided with a control mechanism for driving the plug to move along the axis of the through sleeve. The control mechanism includes a fixed magnetic ring installed on the through sleeve and a movable magnetic ring installed on the plug. The movable magnetic ring is coaxially arranged below the fixed magnetic ring.

[0009] Preferably, at least one of the fixed magnetic ring and the movable magnetic ring is a magnetically conductive ring.

[0010] Preferably, the control mechanism further includes a limiting ring coaxially disposed below the plug body, wherein the plug body is in the lower stop position when the lower end of the plug body contacts the limiting ring.

[0011] Preferably, the limiting ring has a plurality of material discharge ports arranged in a ring.

[0012] Preferably, a plurality of material discharge ports are evenly distributed around the lower end of the through sleeve on its peripheral wall.

[0013] Preferably, the mixing tank is equipped with a stirring shaft, and the plug is sleeved on the stirring shaft along the axis of the stirring shaft. A limiting ring located below the plug is fixedly sleeved on the stirring shaft, and the material discharge port is formed between the peripheral wall of the limiting ring and the inner wall of the sleeve.

[0014] Preferably, the mixing tank is equipped with a stirring shaft, and the plug body is movably sleeved on the stirring shaft along the axis of the stirring shaft. A compression spring sleeved on the stirring shaft is provided between the limiting ring and the plug body. A cylindrical pin is installed on the through sleeve and inserted into the material discharge channel perpendicular to its axis. The outer circumference of the plug body is provided with a contact surface that can cooperate with the peripheral wall of the cylindrical pin. The contact surface is provided with high points and low points at intervals around the circumference of the plug body. When the plug body rotates with the stirring shaft, when the front end of the cylindrical pin moves from the low point to the high point in the contact surface, the plug body moves from the upper stop position to the lower stop position.

[0015] Preferably, the through sleeve is equipped with a locking mechanism for controlling the movement of the cylindrical pin along the axis perpendicular to the through sleeve. When the locking mechanism controls the cylindrical pin to engage with the contact surface, the cylindrical pin is locked.

[0016] This invention also relates to a batching method for an automated batching station system, comprising the following steps:

[0017] S1. Control the material storage unit to start feeding. The batching is conveyed to the designated weighing unit through the feeding unit at a set speed.

[0018] S2. The weighing unit monitors the actual weight of each ingredient in real time. When the set value is reached, the feeding stops and the ingredients are fed into the mixing tank.

[0019] S3. Start the stirring function in the mixing tank until the mixture is uniform. After the mixing is complete, discharge the mixed ingredients.

[0020] S4. Send the discharged ingredients to the testing equipment for quality testing to confirm whether they meet the preset mixing standards.

[0021] Compared with the prior art, the beneficial effects of this application are as follows: The present invention achieves quantitative release of ingredients after mixing for a period of time by intermittently opening and closing the material discharge channel, thereby achieving the effect of preliminary premixing. This allows the ingredients to be initially mixed in the upper mixing chamber, and then the intermittent transfer and further mixing of the ingredients from the upper mixing chamber to the lower mixing chamber is achieved by controlling the reciprocating movement of the plug. This avoids the problem of uneven mixing caused by pouring the ingredients all at once, improves the mixing efficiency, and makes the mixing process more thorough and uniform.

[0037] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0038] like Figure 1-14 An automated batching station system is shown, including a storage unit, a feeding unit, a weighing unit, and a mixing tank 1. The internal space of the mixing tank 1 is provided with a partition 2, which divides the internal space of the mixing tank 1 into an upper mixing chamber 21 and a lower mixing chamber 22. The partition 2 is provided with a through sleeve 3 that extends downward and connects the upper mixing chamber 21 and the lower mixing chamber 22. A plug 4 that can move along the axial direction of the through sleeve 3 is provided inside the through sleeve 3. The plug 4 has an upper stop position and a lower stop position in the axial direction. When the plug 4 is in the upper stop position, the upper peripheral wall of the plug 4 is tightly fitted with the upper edge of the through sleeve 3. When the plug 4 moves from the upper stop position to the lower stop position, a material discharge channel 31 is formed between the peripheral wall of the plug 4 and the inner wall of the through sleeve 3. When the plug 4 is in the lower stop position, the material discharge channel 31 is at its maximum opening. The lower end of the through sleeve 3 is provided with a discharge port 311 that communicates with the material discharge channel 31.

[0039] The top of the mixing tank 1 has multiple inlets 11 for different ingredients to be added, and the bottom of the mixing tank 1 has an outlet 12. The mixing tank 1 is also equipped with an upper agitator 211 installed in the upper mixing chamber 21 and a lower agitator 221 installed in the lower mixing chamber 22. The partition 2 has a bucket-shaped structure, allowing the ingredients to slide down the surface of the partition 2.

[0040] Different types of ingredients are sequentially conveyed from the storage unit to their respective feeding units, and then conveyed to the weighing unit for weighing. Following a preset ratio, they are fed into the upper mixing chamber 21 through multiple inlets 11 at the top of the mixing tank 1. The ingredients received in the upper mixing chamber 21 fall onto the surface of the partition plate 2, where they are initially mixed by the upper agitator 211. When it is necessary to transfer the ingredients from the upper mixing chamber 21 to the lower mixing chamber 22, the movement of the plug 4 is controlled, causing the plug 4 to engage with the lower mixing chamber 22. The gap between the through sleeve 3 gradually increases, that is, the plug 4 moves from the upper stop position to the lower stop position. The plug 4 and the through sleeve 3 are then connected to form a material discharge channel 31 for the ingredients to fall. The ingredients flow into the lower mixing chamber 22 through the material discharge channel 31 and the discharge port 311. When the plug 4 moves to the lower stop position, the material discharge channel 31 reaches its maximum opening. The ingredients in the upper mixing chamber 21 quickly and evenly enter the lower mixing chamber 22, avoiding the ingredients from being poured into the lower mixing chamber 22 all at once, which would cause uneven mixing.

[0041] Meanwhile, the plug 4 is in a reciprocating motion within the through sleeve 3, that is, when the plug 4 moves from the upper stop position to the lower stop position, it moves back from the lower stop position to the upper stop position, realizing the intermittent opening and closing of the material discharge channel 31. This allows the material to be mixed for a period of time, and then the material discharge channel 31 is opened to release a certain amount of the mixed material. Then the material discharge channel 31 is closed to continue mixing the remaining material, ensuring that each discharge is a fully mixed material. Next, the lower agitator 221 in the lower mixing chamber 22 starts to work, further mixing the material from the upper mixing chamber 21. This ensures that all ingredients are thoroughly and evenly mixed, improving mixing efficiency and saving time. It can either open the discharge port 12 at the bottom of the mixing tank 1 after mixing for a period of time, allowing the fully mixed ingredients to flow out from the discharge port 12 and be sent to the next process, or keep the discharge port 12 open at all times, so that the ingredients enter the lower mixing chamber 22 after being mixed in the upper mixing chamber 21 and continue to be mixed. During the mixing process in the lower mixing chamber 22, the ingredients are continuously sent out from the discharge port 12, achieving the effect of uninterrupted feeding, and finally being sent to the next process.

[0042] See Figure 2 and Figure 7 As shown, the mixing tank 1 is equipped with a control mechanism 5 for driving the plug 4 to move along the axis of the through sleeve 3. The control mechanism 5 includes a fixed magnetic ring 51 installed on the through sleeve 3 and a movable magnetic ring 52 installed on the plug 4. The movable magnetic ring 52 is coaxially arranged below the fixed magnetic ring 51.

[0043] The control mechanism 5 operates via a fixed magnetic ring 51 mounted on the through sleeve 3 and a movable magnetic ring 52 mounted on the plug body 4. When it is necessary to transfer the ingredients in the upper stirring chamber 21 to the lower stirring chamber 22, the magnetic pole direction or magnetic force of the fixed magnetic ring 51 and the movable magnetic ring 52 is changed to generate magnetic attraction or repulsion. The magnetic force of the fixed magnetic ring 51 acts on the movable magnetic ring 52. Since the movable magnetic ring 52 is fixedly connected to the plug body 4, it drives the plug body 4 to move up and down along the axis of the through sleeve 3. When the magnetic pole of the movable magnetic ring 52 attracts the magnetic pole of the fixed magnetic ring 51, the plug body 4 moves upward. At this time, the plug body 4 moves to the upper stop position, and the material discharge channel 31 is closed. Conversely, when the magnetic pole of the movable magnetic ring 52 repels the magnetic pole of the fixed magnetic ring 51, the plug body 4 moves downward. At this time, the plug body 4 gradually moves to the lower stop position, and the material discharge channel 31 gradually opens.

[0044] See Figure 7 As shown, at least one of the fixed magnetic ring 51 and the movable magnetic ring 52 is a magnetic ring that is electrically conductive.

[0045] The methods include:

[0046] The fixed magnetic ring 51 is an electromagnetic ring that conducts electricity, and the movable magnetic ring 52 is an electromagnetic ring that conducts electricity. The electromagnetic ring is made of permanent magnet material and has north and south poles. Following the principle that like poles repel and unlike poles attract, it can generate an attractive or repulsive force with another electromagnet. In this combination, the fixed magnetic ring 51 can be energized to generate a magnetic field, which is used to attract or repel the movable magnetic ring 52, thereby changing the position or state of the movable magnetic ring 52 and realizing the control and adjustment of the plug body 4.

[0047] The fixed magnetic ring 51 is a conductive magnetic ring, and the movable magnetic ring 52 is a magnetically energized magnetic ring. The conductive magnetic ring is made of permanent magnet material and has north and south poles. Following the principle that like poles repel and unlike poles attract, it can generate an attractive or repulsive force with another electromagnet. In this combination, the movable magnetic ring 52 can be energized to generate a magnetic field. By changing its own magnetic field strength, it interacts with the fixed magnetic ring 51 to achieve control and adjustment of the plug body 4.

[0048] Both the fixed magnetic ring 51 and the movable magnetic ring 52 are energized magnetic rings. In this combination, both the fixed magnetic ring 51 and the movable magnetic ring 52 can be energized and work together to control the magnetic field strength and direction, thus interacting to control and adjust the plug body 4.

[0049] See Figure 2 and Figure 7 As shown, the control mechanism 5 also includes a limiting ring 53 coaxially disposed below the plug body 4. When the lower end of the plug body 4 contacts the limiting ring 53, the plug body 4 is in the lower stop position.

[0050] When the control mechanism 5 starts and drives the plug 4 to move downward, the plug 4 will move downward along the axis of the through sleeve 3 until its lower end contacts the limiting ring 53. The limiting ring 53 serves as the end position for the downward movement of the plug 4. When the plug 4 contacts the limiting ring 53, it indicates that the plug 4 has reached the lower stop position. At this time, the material discharge channel 31 is at its maximum opening, and the ingredients in the upper stirring chamber 21 can enter the lower stirring chamber 22 to the maximum extent. When the control mechanism 5 controls the plug 4 to move upward until the material discharge channel 31 is closed, that is, the upper end of the plug 4 is in close contact with the upper edge of the through sleeve 3 and is in the upper stop position, the material discharge channel 31 is closed, preventing the ingredients from falling further.

[0051] See Figure 8 As shown, the limiting ring 53 has a plurality of material discharge ports 311 arranged in a ring.

[0052] The limiting ring 53 closes the lower end of the through sleeve 3, serving as the termination position for the downward movement of the plug 4. At this time, the ingredients will fall onto the limiting ring 53. In order to allow the ingredients to enter the lower stirring chamber 22, a discharge port 311 is opened on the limiting ring 53, allowing the ingredients to fall into the lower stirring chamber 22 through the discharge port 311, thus avoiding the risk of blockage.

[0053] See Figure 9 As shown, a plurality of material discharge ports 311 are evenly distributed around the lower end of the through sleeve 3 on its peripheral wall.

[0054] The limiting ring 53 closes the lower end of the through sleeve 3, serving as the termination position for the downward movement of the plug 4. At this time, the ingredients will fall onto the limiting ring 53. In order for the ingredients to enter the lower stirring chamber 22, a discharge port 311 is opened on the peripheral wall of the through sleeve 3, and the discharge port 311 is inclined downward. The surface of the limiting ring 53 is an inclined surface that allows the ingredients to slide towards the discharge port 311, so that the ingredients can fall into the lower stirring chamber 22 through the discharge port 311, avoiding the risk of blockage.

[0055] See Figure 3 , Figure 4 , Figure 10 and Figure 11 As shown, the mixing tank is equipped with a stirring shaft 13, and the plug 4 is movably sleeved on the stirring shaft 13 along the axis of the stirring shaft 13. A limiting ring 53 located below the plug 4 is fixedly sleeved on the stirring shaft 13, and the material discharge port 311 is formed between the peripheral wall of the limiting ring 53 and the inner wall of the through sleeve 3.

[0056] Both the upper agitator 211 and the lower agitator 221 are fixedly mounted on the agitator shaft 13. When it is necessary to transfer the ingredients from the upper agitator chamber 21 to the lower agitator chamber 22, the control mechanism 5 drives the plug body 4 to move downward along the agitator shaft 13. When the plug body 4 moves downward to the position of the limiting ring 53, the plug body 4 contacts the limiting ring 53. At this time, the plug body 4 is in the lower stop position and no longer continues to descend. The limiting ring 53 is fixedly sleeved on the agitator shaft 13, and a discharge port 311 is formed between its peripheral wall and the inner wall of the through sleeve 3. When the plug body 4 moves to the lower stop position, the ingredients falling in the discharge channel 31 flow directly into the lower agitator chamber 22 through the discharge port 311 for further mixing.

[0057] See Figure 3 , Figure 4 and Figures 10-14 As shown, the mixing tank is equipped with a stirring shaft 13. The plug body 4 is movably mounted on the stirring shaft 13 along the axis of the stirring shaft 13. A compression spring 531 is mounted on the stirring shaft 13 between the limiting ring 53 and the plug body 4. A cylindrical pin 54 is installed on the through sleeve 3 and inserted into the material discharge channel 31 perpendicular to its axis. The outer periphery of the plug body 4 is provided with a contact surface 541 that can cooperate with the peripheral wall of the cylindrical pin 54. The contact surface 541 is provided with high points and low points at intervals around the circumference of the plug body 4. When the plug body 4 rotates with the stirring shaft 13, when the front end of the cylindrical pin 54 moves from the low point to the high point in the contact surface 541, the plug body 4 moves from the upper stop position to the lower stop position.

[0058] The peripheral wall of the plug 4 has a plurality of abutting blocks evenly distributed around its circumference, and the abutting blocks have the abutting surface 541.

[0059] The peripheral wall of the plug 4 is provided with an abutment groove around its circumference, and the abutment groove has the abutment surface 541.

[0060] When the front end of the cylindrical pin 54 is at the lowest point of the contact surface 541, the compression spring 531 pushes the plug 4 upward through its compression force, causing the upper peripheral wall of the plug 4 to fit tightly against the upper edge of the through sleeve 3. As the stirring shaft 13 rotates, the stirring shaft 13 drives the plug 4 to rotate synchronously. The surface of the stirring shaft 13 has a retaining strip extending along its axial direction, and the inner wall of the plug 4 has a retaining groove that engages with the retaining strip. This allows the plug 4 to move along the axial direction of the stirring shaft 13 and to rotate synchronously with the stirring shaft 13. As the plug 4 rotates, the front end of the cylindrical pin 54 moves from the lowest point to the highest point within the contact surface 541. During this process, the cylindrical pin 54 remains stationary. Due to the interaction between the cylindrical pin 54 and the contact surface 541, the plug 4 moves downward along the stirring shaft 13. At this time, the compression spring 531 is compressed, and the plug 4 moves from the upper stop position to the lower stop position. During this process, the material discharge channel 31 opens until the front end of the cylindrical pin 54 is at the high point of the contact surface 541. Then, the plug 4 contacts the limiting ring 53, and the material discharge channel 31 reaches its maximum opening. As the plug 4 continues to rotate with the stirring shaft 13, the front end of the cylindrical pin 54 returns to the low point position, the compression spring 531 resets, and the plug 4 moves back to the upper stop position. By the cylindrical pin 54 intermittently passing through the low and high points of the contact surface 541, the intermittent opening and closing of the material discharge channel 31 is achieved.

[0061] See Figures 12-14 As shown, a locking mechanism is installed on the through sleeve 3 to control the movement of the cylindrical pin 54 in a direction perpendicular to the axis of the through sleeve 3. When the locking mechanism controls the cylindrical pin 54 to cooperate with the contact surface 541, the cylindrical pin 54 is locked.

[0062] The cylindrical pin 54 has a resilient abutment head 542 at its front end.

[0063] The locking mechanism controls the elastic contact head 542 at the end of the cylindrical pin 54 to move closer to or away from the peripheral wall of the plug body 4. The locking mechanism is not shown in the figure. When the locking mechanism is activated, it pushes or pulls the cylindrical pin 54, causing the elastic contact head 542 at its front end to move closer to or away from the peripheral wall of the plug body 4. When the cylindrical pin 54 moves away from the plug body 4, there is no interaction between the cylindrical pin 54 and the contact surface 541. At this time, the plug body 4 is always in an upward-push state under the action of the compression spring 531, and the material discharge channel 31 remains closed, which is beneficial for the upper agitator 211 to fully agitate the ingredients on the partition plate 2. After the ingredients have been initially agitated for a period of time, the locking mechanism controls the cylindrical pin 54 to move closer to the plug body 4. When the elastic contact head 542 moves closer to the plug body 4... Upon contact, due to the elastic structure of the elastic contact head 542, the elastic contact head 542 is compressed and the cylindrical pin 54 is locked in the current position. At this time, according to the rotation of the plug body 4, until the elastic contact head 542 passes the contact surface 541, the elastic contact head 542 can enter the contact block or contact groove formed by the contact surface 541, ensuring that the elastic contact head 542 can accurately contact the contact surface 541, ensuring that the cylindrical pin 54 and the contact surface 541 can interact. The elastic contact head 542 will move from the low point to the high point on the contact surface 541, forcing the plug body 4 to move downward along the stirring shaft 13, thereby opening the material discharge channel 31 and realizing the transfer of the ingredients from the upper stirring chamber 21 to the lower stirring chamber 22.

[0064] A batching method for an automated batching station system, applied to an automated batching station system, includes the following steps:

[0065] S1. Control the material storage unit to start feeding. The batching is conveyed to the designated weighing unit through the feeding unit at a set speed.

[0066] S2. The weighing unit monitors the actual weight of each ingredient in real time. When the set value is reached, the feeding stops and the ingredients are fed into the mixing tank 1.

[0067] S3. Start the stirring function in mixing tank 1 until the mixture is uniform. After the mixing is completed, discharge the mixed ingredients.

[0068] S4. Send the discharged ingredients to the testing equipment for quality testing to confirm whether they meet the preset mixing standards.

[0069] This invention achieves the effect of quantitative release of ingredients after a period of mixing by intermittently opening and closing the material discharge channel 31, thus achieving a preliminary premixing effect. This allows the ingredients to be initially mixed in the upper mixing chamber 21, and then the ingredients are intermittently transferred from the upper mixing chamber 21 to the lower mixing chamber 22 and further mixed by controlling the reciprocating movement of the plug 4. This avoids the problem of uneven mixing caused by pouring the ingredients all at once, improves the mixing efficiency, and makes the mixing process more thorough and uniform.

[0070] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
