Description

Technical Field

[0001] This utility model relates to an accessory for an automatic feeding device for a reaction vessel, specifically a feeding operation suitable for fine chemical products production processes with small quantities, multiple feeding points, various varieties, and high frequency, to achieve automatic and precise feeding of solid materials. Background Technology

[0002] In traditional fine chemical production processes, liquid feeding requires the addition of multiple material pipelines, resulting in significant initial investment and frequent pipeline cleaning in the later stages. Solid feeding, on the other hand, relies excessively on manual operation, which has the following drawbacks: it is prone to material leakage, requires high protection for operators, and the operating distance for high-risk processes must be >3m. However, the operating position of traditional manual valves is only 0.5-1.2m away from the reactor opening, resulting in 62% of leakage accidents in the industry in the past three years being related to manual operation. At the same time, there is a lack of real-time weight monitoring, leading to insufficient feeding accuracy.

[0003] Existing automated equipment mostly adopts a fixed connection structure, with mainstream robotic arms having a repeatability accuracy of ±1mm, high leakage frequency, high detection delay, and uncontrollable material environment. It is difficult to adapt to the docking requirements of reactors of different specifications, and cannot meet the standards for successful material feeding.

[0004] Currently, industrialized reactor feeding methods generally suffer from drawbacks such as high labor intensity for workers, hazardous environment, and large feeding errors. Utility Model Content

[0005] The purpose of this utility model is to provide a connection module for an automatic feeding device, which is suitable for use scenarios with many fine chemical products, small feeding amounts each time, many feeding points, high feeding frequency, and many types of materials. This connection module can realize integrated positioning, weighing, and remote control, thereby effectively improving the automation and intelligence of the feeding process and solving the efficiency and safety problems of manual feeding.

[0006] An automatic feeding device connection module includes a funnel, a feeding mechanism, a positioning mechanism, a lifting mechanism, and a weighing module. The feeding mechanism drives a valve inside a hopper to open and close, thereby completing the feeding. The funnel is located directly below the hopper's feeding position. The positioning mechanism moves the hopper to a set position to align the funnel with the hopper, ensuring communication between the funnel and the hopper's interior and side sealing. The lifting mechanism moves the funnel up and down to seal or separate the funnel from the hopper. The weighing module measures the weight of the hopper in real time.

[0007] The funnel has hanging ears installed on both sides of its sidewall. The hanging ears are fixed to the bracket, and the bracket is fixed to the mounting platform to fix the funnel.

[0008] The feeding mechanism has a rotating cylinder, a rotating rod, and a rotating gripper; the rotating cylinder causes the rotating gripper to rotate via the rotating rod; the hopper has a rotating shaft and a linkage block; the rotating gripper drives the rotating shaft to rotate via the linkage block, and the rotating shaft is linked with the feeding valve in the hopper, the shape of which corresponds to the shape of the feeding channel in the hopper to complete the feeding and closing operations of the hopper.

[0009] The rotating gripper has a groove-shaped structure, and the position where the linkage block engages with the rotating gripper has an inclined surface.

[0010] The positioning mechanism includes a telescopic cylinder, a telescopic gripper, and a conical shaft. The telescopic gripper is fixed on the telescopic cylinder and drives the hopper to move to a set position. The conical shafts are arranged symmetrically, and each conical shaft has a V-groove. The V-groove centers and limits the transverse rod of the hopper, ensuring that the assembly error of the hopper and funnel in the hopper meets the requirement of mutual sealing.

[0011] The cone shaft has four sections, which are arranged in a front-to-back alignment.

[0012] The lifting mechanism includes a lifting motor, a connecting rod seat, a lifting seat, and a lifting platform. The lifting motor drives the lifting platform to perform lifting actions through the connecting rod seat and the lifting seat. The hopper is placed on the lifting platform. There are multiple connecting rod seats, one of which is assembled with the lifting motor. This connecting rod seat drives the other connecting rod seats to move, thereby linking the lifting seat. The lifting seat has a screw to drive the lifting platform to lift.

[0013] The linkage seat has three parts, with the middle linkage seat being assembled with the lifting motor. The middle linkage seat drives the couplings of the other two linkage seats to rotate. The couplings drive the screw of the lifting seat to rotate longitudinally. There is also a coupling between the two lifting seats, so that the two lifting seats together drive the lifting platform to perform lifting and lowering actions.

[0014] A weighing module is installed between the lifting seat and the lifting platform to monitor the weight of the hopper in real time.

[0015] The beneficial effects of this utility model are as follows: by designing a feeding mechanism, the material in the hopper is automatically fed into the reactor; by designing a positioning mechanism, the hopper is ensured to be in the set position; by designing a lifting mechanism, the material is easily discharged and separated between the hopper and the reactor; in particular, the cone shaft and the snake gripper in the positioning mechanism form a unique design combination, which can optimize the positioning deviation of the hopper from the original 3-5cm to 3-5mm, thereby ensuring the sealed assembly of the hopper and the reactor.

[0036] Please refer to Figures 1 to 12 The diagram shows a connecting module for an automatic feeding device, mainly designed with components such as a funnel 1, a feeding mechanism 2, a positioning mechanism 3, a lifting mechanism 4, and a weighing module 5. The main design innovation of this connecting module is the precise placement of the hopper 6 onto the connecting module through the cooperation of multiple mechanisms. The funnel 1 primarily guides the material from the hopper 6 into the reaction vessel. The feeding mechanism 2 mainly opens and closes the movable valve 641 or valve plate inside the hopper 6 to complete the feeding. The positioning mechanism 3 mainly positions the hopper 6, i.e., moves the hopper... The 6-position alignment mechanism aligns the funnel 1 with the hopper 6, ensuring internal connection and side sealing between the funnel 1 and the hopper 6. This optimizes the assembly deviation between the hopper 6 and the reactor, ensuring a sealed assembly. The lifting mechanism 4 is used for lifting the hopper 6, facilitating docking between the hopper 6 and the reactor. The weighing module 5 monitors the weight of the hopper 6 in real time, detecting the amount of material entering the reactor from the hopper 6. In practical applications, the above components can be further optimized, additional components can be added, or existing components with the same function can be used to replace the above components.

[0037] The funnel 1 in the figure is a hollow cylindrical structure and is located directly below the material discharge of the silo 6. The side walls on both sides are equipped with hanging ears 71, which are fixed on the bracket 72. The bracket 72 is installed on a corresponding mounting platform 73, so that the funnel 1 can be stably connected to the reactor and the silo 6.

[0038] The hopper 6 in the figure is composed of a conical barrel and a frame, as shown in the figure. The bottom of the conical barrel has a hollow hopper 64 structure, with the funnel 1 directly below the hopper 64 for easy material discharge. The outer side of the hopper 64 has a rotating shaft 61 and a linkage block 62 structure. Inside the hopper 64 is a circular discharge valve 641. When the linkage block 62 is rotated by the rotating gripper 23, it can drive the valve 641 to rotate via the rotating shaft 61. The shape of the valve 641 corresponds to the shape of the material discharge channel of the hopper 6, thus completing the material discharge and closing operations of the hopper 6. That is, when the valve 641 is in a horizontal position, it closes the material discharge channel; when rotated, it opens the material discharge channel. The bottom of the frame has a horizontal rod 63, which facilitates placement on the conical shaft 33 of the positioning mechanism 3.

[0039] The feeding mechanism 2 in the figure is designed with a rotating cylinder 21, a rotating rod 22, and a rotating gripper 23. The rotating cylinder 21 adopts the main component of an angular stroke cylinder, which can drive the rotating rod 22 to rotate at a certain angle, such as 45 or 90 degrees. The rotating rod 22 is a straight rod structure, which transmits the rotation of the rotating cylinder 21 to the rotating gripper 23. The rotating gripper 23 is a U-shaped groove structure, which forms an embedded fit with the linkage block 62 of the hopper 64 of the hopper 6 to achieve synchronous rotation of the linkage block 62. In order to achieve better embedding, the linkage block 62 can be designed with a double-sided inclined structure at the position where it mates with the rotating gripper 23. In practical applications, the rotating gripper 23 can be movably assembled with the rotating rod 22, thus adapting to hoppers 6 of different specifications. The rotating cylinder 21 is driven back and forth by a direct-push cylinder 24 through a traditional slide rail assembly.

[0040] The positioning mechanism 3 in the figure includes a telescopic cylinder 31, a telescopic gripper 32, and a conical shaft 33. There are two telescopic cylinders 31 and two telescopic grippers 32, arranged on the left and right sides. There are four conical shafts 33, arranged symmetrically front and back. The telescopic cylinder 31 uses a conventional direct-push cylinder structure. The telescopic gripper 32 uses an inverted L-shaped structure, so that when the hopper 6 is placed on the conical shaft 33, it pulls the hopper 6 inward and moves it to the set position. Each conical shaft 33 has… The V-groove structure corresponds to a straight rod structure for the horizontal rod 63 at the bottom of the hopper 6. When the horizontal rod 63 falls into the V-groove, it can be centered. Centering means that when the hopper 6 is slightly deviated to the left or right, the V-groove will correct its position due to the characteristics of the V shape, so that the axis of the hopper 6 is aligned with the axis of the funnel 1 or has only a small deviation. This ensures that the assembly error of the hopper 64 on the hopper 6 and the funnel 1 meets the requirements for mutual sealing.

[0041] The lifting mechanism 4 in the figure drives the funnel 1 to rise and fall, so that the funnel 1 can be sealed and assembled or separated from the silo 6. The lifting mechanism 4 is designed with a lifting motor 41, a connecting rod seat 43, a lifting seat 42, and a lifting platform 44. The lifting motor 41 is used to drive one of the connecting shafts 45 of the connecting rod seat 43 to rotate, thereby driving the internal components of the lifting seat 42 to rotate. The lifting seat 42 can drive the lifting platform 44 to perform lifting and lowering actions. The lifting platform 44 is used to support the silo 6. A single lifting motor 41 is used, as shown in the figure. The motor's shaft rotates synchronously with a connecting shaft 45 of the connecting rod seat 43. The specific structure of each connecting rod seat 43 can be seen in the figure. The connecting rod seat 43 is an existing component, with a connecting shaft 45 on each of its three sides. Each connecting shaft 45 is driven by meshing bevel gears with the other connecting shafts 45. That is, the rotation of one connecting shaft 45 can synchronously drive the other two connecting shafts 45 to rotate. The figure shows three connecting rod seats 43. One connecting rod seat 43 is matched with one lifting motor 41. This connecting rod seat 43 is also matched with the remaining two connecting rod seats 43, so that the lifting motor 41 drives the connecting shafts 45 on the other two connecting rod seats 43 to rotate synchronously through this connecting rod seat 43. The lifting seats 42 also have an existing structure, with four of them arranged symmetrically front and back like the conical shaft 33. Adjacent lifting seats 42 are connected by a coupling 45 to achieve synchronous rotation. A connecting component, such as a coupling, is also provided between the lifting seats 42 and the connecting rod seats 43, allowing the connecting rod seats 43 to drive the movement of components within the lifting seats 42. The lifting seats 42 also employ a meshing bevel gear structure with a longitudinally arranged screw structure. This screw can be driven by the coupling 45 to perform lifting actions, which in turn drive the lifting platform 44 to perform lifting actions. To monitor the weight change of the material hopper 6 on the lifting platform 44, a weighing module 5 can be installed between each lifting seat 42 and the lifting platform 44. The connections between the connecting rod seats 43 and the lifting seats 42, between the connecting rod seats 43 and each other, and between the lifting seats 42 can all be made in the existing manner; therefore, the specific connection structures are omitted in the figure.
