Description

Technical Field

[0001] This utility model relates to the field of fluid automatic control technology, and in particular to an automated feeding system. Background Technology

[0002] In existing technologies, the synthesis of a finished product often requires the addition of multiple fluid or liquid raw materials into a mixer for mixing or reaction, ultimately producing the final product. Currently, the industry uses manual addition of various raw materials. However, manual addition has several drawbacks. First, it is prone to uneven addition, leading to prolonged mixing time, excessively high temperature rise in the finished product, and inconsistent product quality. Second, during manual addition, air and dust can easily enter the mixer, causing the mixture or reaction to form a crust containing air or particulate matter containing dust, resulting in a finished product that does not meet quality requirements.

Detailed Implementation

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] As attached Figure 1 As shown, the present invention provides an automated feeding system, including...

[0025] Multiple storage devices 1 are provided, each including a storage tank 11 and a first weighing device 12. The bottom of the storage tank 11 has an inlet and an outlet. A first discharge pump 13 is installed at the outlet, and the first weighing device 12 is installed below the storage tank 11. The multiple storage tanks 11 are used to temporarily store different liquid or fluid raw materials, which are pumped out by the first discharge pump 13. The entire storage tank 11 is mounted on the first weighing device 12, which weighs and displays the amount of raw material in the storage tank 11, thus continuously replenishing it.

[0026] Multiple metering devices 2 are provided, each corresponding to a set of material storage devices 1. Each metering device 2 includes a metering cylinder 21 and a second weighing device 22. The metering cylinder 21 includes a frame 211, a cylinder body 212, a pressure plate 213, and a drive mechanism 214. The cylinder body 212 and drive mechanism 214 are mounted on the frame 211. The output end of the drive mechanism 214 is connected to the pressure plate 213, which is located inside the cylinder body 212. The bottom of the cylinder body 212 has an inlet end and an outlet end. A second discharge pump 23 is installed at the outlet end, and the second weighing device 22 is installed below the frame 211. Specifically, the multiple cylinder bodies 212 are used to store and meter the corresponding liquid or fluid raw materials. The drive mechanism 214 can be either a hydraulic cylinder or an electric cylinder. The second weighing device 22 can weigh and display the weight of the raw materials in the cylinder body 212. Normally, the raw material in the cylinder 212 is filled at once, and then the pressure plate 213 is driven by the drive mechanism 214 to press out the raw material in the cylinder 212 at once until the raw material inventory is zero.

[0027] The mixer 3 has multiple feed ends and one discharge end at the bottom of its feed cylinder 31. The feed cylinder 31 is used to uniformly receive raw materials from multiple sets of cylinders 212, and after the mixing reaction, the finished product is discharged from the discharge end. Preferably, a discharge pump is also installed at the discharge end of the feed cylinder 31 to uniformly discharge the finished product.

[0028] The discharge ends of multiple sets of first discharge pumps 13 are respectively connected to the inlet ends of multiple sets of cylinders 212 through the first pipeline 4, and the discharge ends of multiple sets of second discharge pumps 23 are respectively connected to multiple inlet ends of material cylinder 31 through the second pipeline 5.

[0029] This invention uses a first weighing device 12 to weigh the raw material in the storage tank 11, ensuring a continuous supply of raw materials. The raw material from the storage tank 11 is then pumped into the metering cylinder 212. A second weighing device 22 weighs the entire cylinder 212, ensuring that the weight of the raw material entering the mixing cylinder 31 from the cylinder 212 is consistent and accurate, thus guaranteeing consistent product quality. Furthermore, the entire feeding process is automated, requiring no manual intervention, and prevents air and dust from entering the mixing cylinder 3, ensuring the finished product meets quality requirements.

[0030] Furthermore, since the density of raw materials varies due to temperature and pressure under different environments, compared to using volume measurement, the advantage of using the second weighing device 22 of the metering device 2 to weigh all raw materials entering the material cylinder 31 individually is that it is not affected by changes in the density of the raw materials. This makes the amount of raw materials added more accurate and consistent, ensures consistent mixing time, avoids excessive temperature rise, and results in better quality of the finished product.

[0031] The automated feeding system also includes a control panel (not shown in the figure), which is electrically connected to multiple sets of material storage devices 1, multiple sets of metering devices 2, and a mixer 3. The first weighing device 12 feeds back the information on the raw material inventory in the storage tank 11 to the control panel. The control panel controls the material storage device 1 to replenish the raw material in the storage tank 11, and pumps the raw material in the storage tank 11 into the cylinder 212 of the metering cylinder 21 through the first discharge pump 13. When the raw material inventory in the cylinder 212 reaches the specified data, the second weighing device 22 feeds back the information to the control panel. The control panel controls the metering device 2, and drives the pressing plate 213 through the drive mechanism 214 to press the raw material in the cylinder 212 into the material cylinder 31 of the mixer 3 in one go, realizing automated feeding without manual intervention.

[0032] The first weighing device 12 and the second weighing device 22 are either platform scales or weighbridges. Weighbridges are preferred; the specifications of the weighbridge can be selected based on the amount of raw materials used.

[0033] As attached Figure 2-3 As shown, both the first discharge pump 13 and the second discharge pump 23 are reciprocating piston pumps 6. The reciprocating piston pump 6 includes a pump body 61 with a chamber 611, a piston 62, and two hydraulic cylinders 63. The piston 62 is movably disposed within the chamber 611, dividing the chamber 611 into two material chambers 612. The pump body 61 has one inlet 613 and two outlets 614. Specifically, the inlet 613 is located at the top of the pump body 61 in the middle position, while the two outlets 614 are located at the bottom of the pump body 61, at the left and right ends. The two outlets 614 correspond to the two material chambers 612, and are mirror-symmetrical about the inlet 613. The two hydraulic cylinders 63 are installed at both ends of the pump body 61, and the output shafts of the two hydraulic cylinders 63 are connected to both ends of the piston 62 via piston rods 64, respectively. The output shafts of the two hydraulic cylinders 63 are respectively connected and fixed to the two piston rods 64, and the two piston rods 64 are respectively connected and fixed to both ends of the piston 62. The two discharge ports 614 discharge material through the same discharge pipe, forming the discharge end.

[0034] The reciprocating piston pump 6 described above divides the chamber 611 into two material chambers 612 by a piston 62 movably disposed within the chamber 611. With the sequential drive of two hydraulic cylinders 63, the piston 62 reciprocates, thereby distributing the material entering from the feed inlet 613 into the two material chambers 612 and discharging it from the two discharge ports 614 corresponding to the two material chambers 612. This allows one reciprocating movement of the piston 62 to achieve the effect of discharging material from both discharge ports 614, thereby accelerating the discharge speed and meeting the requirements of rapid production.

[0035] Further details are attached. Figure 3-4As shown, a first annular groove 621 is provided on the outer side wall of the piston 62, and an O-ring 622 is provided in the first annular groove 621. The O-ring 622 is in movable cooperation with the inner wall of the two material chambers 612 to achieve the effect of movable sealing.

[0036] In some embodiments, as shown in the appendix Figure 3-4 As shown, two piston rods 64 are connected to piston 62 via connector 641. Specifically, connector 641 is columnar and passes through a through hole on piston 62 and is fixed to piston 62. One end of each of the two piston rods 64 is nested in the two ends of connector 641, thereby connecting and fixing piston rods 64 and connector 641. One end face of each of the two piston rods 64 abuts against the two end faces of piston 62, thereby reducing the penetration of raw materials into the connection gap between piston rods 64 and piston 62.

[0037] In addition, as a further improvement, see attached... Figure 3-4 As shown, a second annular groove 642 is provided in the middle of the connector 641, and a fixing sealing ring 643 is provided in the second annular groove 642. The fixing sealing ring 643 is used to keep the relative position between the connector 641 and the piston 62 unchanged. The fixing sealing ring 643 abuts against the inner wall of the through hole, thereby preventing the material in one material chamber 612 from seeping into the other material chamber 612 through the gap between the piston 62 and the connector 641, and ensuring that the output of the two discharge ports 614 is uniform.

[0038] Further details are attached. Figure 3-4 As shown, guide sleeves 65 are provided on both end walls of the pump body 61. The piston rod 64 passes through the guide sleeves 65 and is movably engaged with them, which guides the piston rod 64 and reduces force loss. Similarly, multiple third annular grooves 651 are formed on the inner wall of the guide sleeves 65. Movable sealing rings 652 are provided in the third annular grooves 651, and the movable sealing rings 652 are movably engaged with the piston rod 64. The movable sealing rings 652 are used to seal the piston rod 64 when it is in relative motion with the guide sleeves 65, providing a sealing effect during movement.

[0039] As attached Figure 3-4 As shown, the hydraulic cylinder 63 is equipped with a position sensor 67, and the end of the piston rod 64 away from the piston 62 is equipped with a light-shielding plate 671 that cooperates with the position sensor 67. The position sensor 67 and the light-shielding plate 671 cooperate to accurately determine the movement range of the piston rod 64, ensuring that the discharge volume of the two discharge ports 614 is consistent.

[0040] Traditional gear pumps generate heat during discharging and cannot discharge under vacuum. The reciprocating piston pump 6 of this invention offers superior sealing and can be used for discharging and packaging materials from a mixer 3 during vacuum mixing operations. It can also be used for discharging materials from pressurized tanks, storage cylinders 31, and metering cylinders 21 via pressurized inlets 613, ensuring minimal temperature rise in the material and guaranteed discharge pressure.

[0041] Traditional equipment often results in uneven feeding, requiring excessively long mixing times, and excessively high material temperatures. It also easily attracts dust from the air during feeding, leading to the formation of granular material. After processing, the material is pushed out of the feeding cylinder 31 and packaged using a press. However, the material easily contains air, causing some of it to become crusty material, affecting quality and making accurate control of the packaging and metering difficult.

[0042] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
