Description

Technical Field

[0001] The utility model relates to the technical field of automatic feeding of mixers, in particular to a material tank, a grasping mechanism and a discharging device for automatic feeding. Background Technique

[0002] Powder metallurgy is a process of using metal powders (or mixtures of metal powders and non-metal powders) as raw materials to manufacture metal materials, composite materials and various types of products through shaping and sintering. With the development of powder metallurgy technology, the performance requirements of powder metallurgy products are also continuously improving.

[0003] For example, the Chinese patent document with the publication number CN202988264U discloses a powder molding product processing device. The processing device is arranged on a workbench. The processing device includes a control mechanism and a picking mechanism, a deburring mechanism, a conveying mechanism and a detection mechanism respectively connected to the control mechanism. The picking mechanism is arranged on one side of the workbench, and the deburring mechanism and the conveying mechanism are sequentially arranged on one side of the workbench relative to the picking movement direction of the picking mechanism.

[0004] Although the above solution can simplify the post-processing work of the molded products, the powder filling process is not automated. In the prior art, powder feeding is generally carried out manually. During this process, there will be contact between the limbs and the mold, which increases the danger of the operators. Moreover, due to manual feeding, the powder filling will be uneven.

[0005] Especially in some production processes with relatively larger sizes, the amount of metal powder required is very large, and a mixer is needed for mixing. In order to improve efficiency, the capacity of a mixer can even hold up to 500 kilograms of metal powder. And manual feeding can usually only feed about 20 kilograms at a time, resulting in relatively low feeding efficiency. Workers' long-term high-intensity labor is also likely to cause physical strain.

[0006] Therefore, it is necessary to develop a material tank, a grasping mechanism and a discharging device for automatic feeding, so that the material tank can load 500 kilograms of materials at one time, and the improved grasping mechanism is used to grasp and move the material tank, and then the improved discharging device is used to put the materials loaded inside the material tank into the corresponding mixer to meet the requirements of the mixer for mixing, greatly improving the feeding efficiency and optimizing the production efficiency.

Specific embodiments

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 to 6 , in the embodiment of the present invention, a material tank for automatic feeding includes a material tank body 10, an inlet butterfly valve 11 and a material distribution butterfly valve. The inlet butterfly valve 11 is installed at the upper tank body inlet of the material tank body 10 to close or open the tank body inlet; the material distribution butterfly valve is installed at the lower tank body outlet of the material tank body 10 to close or open the tank body outlet; a grabbing hook 12 is provided at the upper part of the material tank body 10. One end of the grabbing hook 12 is fixedly connected to the material tank body 10, and the other end thereof can be grabbed and fixed for operation, so as to perform the moving operation of automatic feeding of the material tank body 10.

[0036] Specifically, the size of the material tank body 10 can be set to a diameter of about 900 MM and a height of about 1300 MM (the size is for reference only and is subject to the specific design). The designed material capacity of the material tank is 500 KG of a material with a density of 3.1 G per cubic centimeter. Also, due to the relatively heavy material tank and the material loaded inside, the grabbing hook 12 can be provided, so that the grabbing mechanism 20 can form a firm grab on the material tank by locking the grabbing hook 12, which is convenient for subsequent movement or transportation.

[0037] Secondly, the material tank is provided with three valves. One of them is that an inlet butterfly valve 11 can be provided at the tank body inlet, and preferably a manual butterfly valve is used for feeding.

[0038] Second, a distributing disc valve 16 can be arranged at the outlet of the tank body. Preferably, a wafer hard-sealed butterfly valve is adopted, and the opening and closing operations of the valve can be carried out through the distributing valve opening assembly 40 of the discharging device 30, so as to quantitatively output the materials inside the storage tank. The wafer hard-sealed butterfly valve adopts a precise J-shaped elastic sealing ring and a triple eccentric multi-level metal hard-sealing structure, and is widely used in industrial pipelines such as metallurgy, electric power, petrochemical industry, water supply and drainage, and municipal construction where the medium temperature ≤ 425 °C, for regulating the flow rate and cutting off the fluid.

[0039] Thirdly, as Figure 2 and Figure 6 shown, preferably, it further includes an inserting sealing valve 18, and the inserting sealing valve 18 is movably connected to the forklift pallet 14 for adding a sealing operation to the outlet of the tank body. At the outlet of the tank body, below the distributing disc valve, an inserting sealing valve 18 can also be added, and a simple sealing plate 19 structure can be adopted to conduct a second closed protection on the outlet of the tank body, which can not only protect the materials when the distributing disc valve fails, but also prevent a small amount of residual materials on the distributing disc valve from falling during the movement and transportation of the tank body.

[0040] As Figure 1 shown, preferably, a spare lifting ring 13 is also arranged on the upper part of the storage tank, and the spare lifting ring 13 is fixedly connected to the outer wall of the storage tank body 10 and can be tied, lifted and fixed, so as to conduct the moving operation of automatically loading the storage tank body 10.

[0041] Specifically, in other transportation places, a targeted grasping mechanism 20 may not be set, so a spare grasping ring can also be arranged on the outer wall of the storage tank body 10, so that other general tools such as chains or steel cables can be used to grasp and move the storage tank.

[0042] As Figure 1 and Figure 3 shown, preferably, the storage tank body 10 is also provided with a forklift pallet 14, and one end of the forklift pallet 14 is fixedly connected to the lower part of the storage tank body 10 to form a support for the storage tank body 10; the other end is used for the external forklift to load and transport the storage tank body 10.

[0043] Specifically, in order to optimize the placement and transportation of the storage tank, a forklift pallet 14 can be set, which can not only stably support the storage tank body 10, but also enable the external forklift to directly load and transport the storage tank body 10, further improving the overall operation efficiency.

[0044] In another embodiment, as Figure 1 、 Figure 2 and Figure 3As shown, preferably, a grasping mechanism 20 is further provided for grasping and fixing the material tank. The grasping mechanism 20 includes a grasping rod 21 and a grasping hook seat 22. One end of the grasping rod 21 is fixedly connected to the driving end of the external truss mechanism, and the other end is fixedly connected to the grasping hook seat 22. One end of the grasping hook seat 22 is fixedly connected to the grasping rod 21, and the other end is used to latch the grasping hook 12, thereby forming a grasping and fixing operation on the material tank body 10.

[0045] The grasping hook seat 22 is provided with a hook seat pin hole 23, a latching pin shaft 24, and a push-pull cylinder 25. The hook seat pin hole 23 is arranged at the part of the grasping hook seat 22 corresponding to the grasping hook 12. The latching pin shaft 24 passes through the hook seat pin hole 23 and moves a certain distance along the hook seat pin hole 23, thereby forming a latching operation on the grasping hook 12. The push-pull cylinder 25 is installed on the grasping hook seat 22, and the latching pin shaft 24 is connected to the piston rod of the push-pull cylinder 25, so that the push-pull cylinder 25 drives the latching pin shaft 24 to move in the hook seat pin hole 23.

[0046] Specifically, in order to optimize the movement and transportation operations of the large-weight material tank, a matching grasping mechanism 20 can also be set. By further arranging a grasping hook 12 at the upper part of the material tank body 10, the grasping mechanism 20 can be used to perform a unified grasping operation on the material tank, improving the stability when moving the material tank and preventing the material tank from accidentally falling during the movement and transportation process.

[0047] Secondly, the grasping hooks 12 can be arranged on both sides of the material tank body 10 respectively, and the grasping mechanism 20 can also be provided with two groups of grasping hook seats 22 and latching pin shafts 24 at the positions corresponding to the grasping hooks 12 on both sides respectively, so that the grasping mechanism 20 can grasp the material tank from both sides respectively, improving the stability and firmness of the grasping.

[0048] As Figure 3 shown, preferably, the grasping hook seat 22 is further provided with a T-shaped transmission member 26. One end of the T-shaped transmission member 26 is fixedly connected to the piston rod of the push-pull cylinder 25, and the other end is sleeved on the latching pin shaft 24, thereby transmitting the movement torque of the push-pull cylinder 25 to the latching pin shaft 24.

[0049] Specifically, the grasping hooks 12 on the same side of the material tank body 10 can also be set as two hook claws with a certain space interval. The T-shaped transmission member 26 is sleeved on the latching pin shaft 24, and one end of it extends into the space between the two hook claws, thereby pushing the two ends of the latching pin shaft 24 into the two hook claws synchronously. After the grasping mechanism 20 moves upward a certain distance, the two hook claws can respectively hook the two ends of the latching pin shaft 24, thereby realizing the latching of the hook claws and forming a grasping operation on the material tank.

[0050] In another embodiment, as Figure 4 、Figure 5 and Figure 6 As shown, preferably, the present utility model further provides a feeding device 30 for carrying and feeding a material tank, and putting the materials loaded inside the material tank body 10 into a mixer to be fed. The feeding device 30 includes a feeding support 31, a lifting electric cylinder 32, a linear bearing 33, a cylindrical shaft 34, and a carrying platform 35. The feeding support 31 is installed above the mixer for supporting the feeding device 30. The lifting electric cylinder 32 and the linear bearing 33 are respectively installed on the feeding support 31. The cylindrical shaft 34 and the linear bearing 33 cooperate with each other to form a linear motion system. The carrying platform 35 is fixedly connected to the lower end of the cylindrical shaft 34 and is in transmission connection with the output shaft of the lifting electric cylinder 32, so that the lifting electric cylinder 32 operates to drive the carrying platform 35 to move up and down a certain distance, thereby docking the tank outlet of the material tank body 10 with the feeding inlet of the mixer.

[0051] Specifically, since the carrying platform 35 needs to carry the material tank, preferably, the linear bearing 33 is a flange type linear bearing 33 that can carry a large load, and two groups of linear bearings 33 and cylindrical shafts 34 are simultaneously arranged at both ends of the feeding support 31, forming a total of four groups of linear motion systems, so as to stably support and move the carrying platform 35. The lifting electric cylinder 32 is preferably a screw lifting electric cylinder or a ball screw electric cylinder with a large load-bearing capacity and good self-locking performance, so as to stably drive the carrying platform 35.

[0052] As Figure 5 shown, preferably, the carrying platform 35 is further provided with a guiding and positioning column 36. One end of the guiding and positioning column 36 is fixedly connected to the carrying platform 35, and the other end forms a free end. The forklift tray 14 is provided with a positioning hole 15 corresponding to the position of the guiding and positioning column 36, so that the guiding and positioning column 36 can penetrate into the positioning hole 15.

[0053] Specifically, when the grasping mechanism 20 puts the material tank body 10 onto the carrying platform 35 of the feeding device 30, the positioning hole 15 provided on the forklift tray 14 at the bottom of the material tank can be sleeved on the tip of the guiding and positioning column 36, so as to guide, orient, and position the material tank body 10, and place it at the correct preset position.

[0054] As Figure 5 shown, preferably, the carrying platform 35 is further provided with a weighing and feedback mechanism 37 for weighing the material tank body 10 and feeding back the weighed weight.

[0055] Specifically, in the automatic feeding conveying system, a corresponding control module can be set so that the control module can receive the weighed weight fed back by the weighing feedback mechanism 37 and select the next operation action according to the weighed weight. For example, when the weights of the materials required by different mixers are different, the on-off control of the distribution butterfly valve can be performed according to the weighed weight of the weighing feedback mechanism 37, so that the corresponding weight of the material is put into the corresponding mixer.

[0056] As Figure 4 and Figure 5 As shown, preferably, the discharging device 30 is further provided with a distribution valve opening assembly 40 for opening or closing the distribution butterfly valve; the distribution butterfly valve is provided with a valve opening connecting rod 17, and the distribution valve opening assembly 40 is provided with a distribution motor 41 and a distribution adapter sleeve 42. The distribution motor 41 is installed on the bearing platform 35, one end of the distribution adapter sleeve 42 is fixedly connected to the output shaft of the distribution motor 41, and the other end thereof is drivably connected to the valve opening connecting rod 17, so that the distribution motor 41 operates to drive the distribution adapter sleeve 42 to rotate, and drives the valve opening connecting rod 17 to rotate synchronously, thereby driving the distribution butterfly valve to open or close.

[0057] Specifically, after the tank body 10 is placed on the bearing platform 35, the lifting electric cylinder 32 drives the bearing platform 35 to move downward, so that the discharging valve below the tank is docked with the feeding inlet of the mixer. Subsequently, the distribution valve opening assembly 40 can be used to open the distribution butterfly valve, so that the material inside the tank can flow into the mixer for corresponding stirring operations.

[0058] In another embodiment, the distribution valve opening assembly 40 is further provided with a front cylinder 43 and a front push plate 44. The front cylinder 43 is installed on the bearing platform 35, the front push plate 44 is fixedly connected to the piston end of the front cylinder 43, and the distribution motor 41 is fixedly connected to the front push plate 44, so that the front cylinder 43 operates to drive the front push plate 44 to move a certain distance, and synchronously drives the distribution motor 41 and the distribution adapter sleeve 42 to move a certain distance in the direction of the valve opening connecting rod 17, so that the distribution adapter sleeve 42 is drivably connected to the valve opening connecting rod 17.

[0059] Specifically, in order that the distribution valve opening assembly 40 does not block the falling of the tank body 10 when the tank body 10 is placed, the front cylinder 43 and the front push plate 44 can be set. When the distribution butterfly valve does not need to be opened, the distribution adapter sleeve 42 and the distribution motor 41 can be moved a certain distance away from the tank. When the valve opening operation needs to be performed, the front cylinder 43 can be opened to push the distribution motor 41 and the distribution adapter sleeve 42 to move a certain distance in the direction close to the tank, so that the distribution adapter sleeve 42 can be drivably connected to the valve opening connecting rod 17.

[0060] As Figure 5 andFigure 6 As shown, preferably, the feeding device 30 is further provided with an inserting valve opening and closing assembly 50 for opening or closing the inserting sealing valve 18; the inserting sealing valve 18 is provided with a sealing plate pair 19, and the inserting valve opening and closing assembly 50 is provided with an inserting cylinder 51 and an inserting connecting member 52. The inserting cylinder 51 is installed on the carrying platform 35. One end of the inserting connecting member 52 is fixedly connected to the piston end of the inserting cylinder 51, and the other end thereof is drivably connected to the sealing plate pair 19, so that the inserting cylinder 51 operates to drive the inserting connecting member 52 to move, thereby opening or closing the inserting sealing valve 18.

[0061] Specifically, in order to further seal and protect the outlet of the tank body, an inserting sealing valve 18 can also be provided. Therefore, a corresponding valve opening assembly also needs to be provided on the feeding device 30 so that it can open or close the inserting sealing valve 18.

[0062] During operation, the external truss mechanism can be used to control the gripping mechanism 20 to move to the corresponding position according to the instruction. After gripping the tank body 10, it moves to directly above the corresponding mixer station, and sends an instruction to the mixer. The mixer opens the docking material port for docking.

[0063] The feeding device 30 is also required for assistance. The truss mechanism controls the gripping mechanism 20 to descend a certain height, places the tank body 10 on the carrying platform 35 of the feeding device 30, the gripping mechanism 20 releases the locking pin 24, the truss mechanism controls the gripping mechanism 20 to rise a certain height, and then the truss mechanism controls the gripping mechanism 20 to return to the original position or empty position synchronously, waiting for the next operation instruction.

[0064] Subsequently, the feeding device 30 can control the carrying platform 35 to move downward a certain distance to dock the discharge port of the tank with the feed port of the mixer. Subsequently, the control module can control the distribution butterfly valve and the inserting sealing valve 18 to be opened synchronously, so that the materials loaded inside the tank flow into the mixer, completing the feeding operation of the materials and improving the operation efficiency of the entire mixer station.

[0065] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed by the present invention.
