Description

Technical Field

[0001] The present invention relates to the technical field of powder recovery devices, and more particularly, to an efficient automatic tipping station. Background Art

[0002] In the production process of new energy batteries, chemical reactions of powders are involved. When the powders are used up, they need to be recovered. The powders are transported on the production line through a bowl. When recovering, after the bowl transports the powders to a certain position, they are collected by a recovery device. Since the powders are likely to be dispersed in the air, during the transportation of the bowl, a closed box is generally provided on the conveyor line to prevent the powders from being dispersed into the air and affecting the environment and operators. However, the existing recovery devices have the problem of low working efficiency. At the same time, the powders dispersed in the box are likely to adhere to the transmission parts, causing great cleaning trouble and easily leading to equipment shutdown. Summary of the Invention

[0003] The present invention discloses an efficient automatic tipping station with a simple structure and convenient operation, aiming to improve the problems of low efficiency of the existing tipping devices and high failure rate easily affected by floating objects.

[0004] The present invention adopts the following solutions:

The guide wheel set includes two lateral wheels adapted to be stuck on opposite side surfaces of the vertical guide rail and an inner roller pressing against the inner side surface of the vertical guide rail to be guided by the guide wheel set when the lifting table moves.

[0007] Further, a buffer device is arranged at the bottom of the lifting frame.

[0008] Further, a lifting door is arranged on one side of the lifting frame connected to the first weighing pipeline mechanism and the second weighing pipeline mechanism.

Detailed implementation manners

[0025] Combined with Figures 1 to 7 As shown in the figure, this embodiment provides an efficient automatic discharging station, including a mounting table 1, on which a first weighing conveyor mechanism 2, a tipping and discharging mechanism 3, a material receiving bin 4, a reverse feeding mechanism 6 and a second weighing conveyor mechanism 7 are arranged; among them,

[0026] The weighing conveyor mechanism is connected to one side of the tipping and discharging mechanism 3, and includes a weighing system and a conveyor device 21. The weighing system is adapted to weigh the bowl body 10 passing through the conveyor device 21, and the conveyor device 21 is adapted to transport the bowl body 10 to the tipping and discharging mechanism 3;

[0027] The tipping and discharging mechanism 3 is arranged above the material receiving bin 4, and is adapted to turn at least two bowl bodies 10 so that the powder in the bowl bodies 10 falls into the material receiving bin 4;

[0028] The reverse feeding mechanism 6 is connected to the material receiving bin 4, and includes a vacuum device 61. The vacuum device 61 is connected to the inside of the tipping and discharging mechanism 3 and the weighing conveyor mechanism through a vacuum pipeline to collect the powder scattered in the tipping and discharging mechanism 3 and the weighing conveyor mechanism, and introduce the powder into the material receiving bin 4;

[0029] The second weighing conveyor mechanism 7 is connected to the other side of the tipping and discharging mechanism 3 to perform secondary weighing on the bowl body 10 after discharging, and convey the bowl body 10 to the next working station.

[0030] Combined with Figure 1As shown, in this embodiment, in the production of new energy batteries, a large amount of powder device raw materials are used. The powder is transported through the bowl body 10, and after use, the powder is recycled through the bowl body 10. Through the transmission of the bowl body 10, the powder rotates with the bowl body 10 in different processes. This embodiment mainly focuses on the process of transporting the powder in the bowl body 10 to the receiving bin 4 during powder recycling. Since the height and volume of the receiving bin 4 are relatively large, stairs, fences and other devices are provided on the installation table 1 to facilitate users' maintenance operations.

[0031] Combined with Figures 1 to 4As shown, an outer enclosure frame, a conveyor line mechanism, and a weighing system are provided on both the first weighing conveyor line mechanism 2 and the second weighing conveyor line mechanism 7. The weighing system is an existing weighing device, which is used to weigh the pot body 10 and the powder material after the pot body 10 enters. The outer enclosure frame is used to wrap the conveyor line mechanism and the weighing system. The first weighing conveyor line mechanism 2 and the second weighing conveyor line mechanism 7 are connected to both sides of the tipping and discharging mechanism 3, and a liftable gate is provided at the connection. On the other side of the first weighing conveyor line mechanism 2 and the second weighing conveyor line mechanism 7 away from the tipping and discharging mechanism 3, a first lifting mechanism 8 and a second lifting mechanism 9 are provided. Both the first lifting mechanism 8 and the second lifting mechanism 9 include a lifting frame 81, and a lifting platform 82, a lifting motor 86, and a lifting belt 87 provided inside the lifting frame 81. The lifting platform 82 is connected to the lifting motor 86 through the lifting belt 87 to lift under the control of the lifting motor 86. A vertical guide rail 811 is provided on the lifting frame 81. The lifting platform 82 includes a conveying line device 83 adapted to place and convey a plurality of the pot bodies 10 and a guide wheel set 85 provided outside the lifting platform 82. The guide wheel set 85 includes two lateral wheels 851 adapted to be stuck on opposite side surfaces of the vertical guide rail 811 and an inner roller 852 pressing against the inner side surface of the vertical guide rail 811 to guide through the guide wheel set 85 when the lifting platform 82 moves up and down. Specifically, the lifting frame 81 includes a frame, the lifting motor 86 is provided at the top of the frame, and buffer devices 812 are provided at the bottom and the top inside the frame respectively to buffer the lifting platform 82 when the belt breaks or the motor gets out of control. The buffer device 812 can adopt rubber blocks. Two vertical guide rails 811 are provided, which are arranged on two opposite side surfaces of the lifting frame 81 and are used to cooperate with the guide wheel set 85 of the lifting platform 82, so that the lifting platform 82 is guided by the two vertical guide rails 811 when lifting, making the lifting more stable. A protective plate 89 is provided on the outside of the lifting frame 81 to keep the inside of the lifting frame 81 relatively sealed and prevent the powder material in the pot body 10 from spreading outside the equipment. A lifting door 810 is provided on one side of the lifting frame 81 connected to the first weighing conveyor line mechanism 6 and the second weighing conveyor line mechanism 7 to control the on-off between the lifting mechanism and the tipping and discharging mechanism 3. When the lifting door 810 rises, the pot body 10 can be conveyed.

[0032] Combined with Figure 4As shown, the lifting table 82 includes a lifting frame 821. At the top and bottom of the lifting frame 821, there are connecting wheels 822 for connecting with the lifting belt 87. In this embodiment, two connecting wheels 822 are provided at both the top and bottom of the lifting frame 821. A transmission assembly line device 83 is arranged inside the lifting frame 821. On both sides of the transmission assembly line, there are limiting devices 84 for holding the bowl body 10 to fix the bowl body 10 after the lifting door 810 is closed. At the bottom of the transmission assembly line device 83, there is a driving roller 831, which is driven by a motor and a chain to drive the bowl body 10 placed on the transmission assembly line to move back and forth. Preferably, a guiding roller 832 is arranged on the side of the transmission assembly line device 83 for holding the side of the bowl body 10 to play a guiding role and prevent the side of the bowl body 10 from being skewed due to large frictional force after contacting the side of the transmission assembly line.

[0033] Combined with Figures 5 to 6As shown, the overturning and unloading mechanism 3 includes a sealed cabin 31, a overturning wheel frame 32 arranged in the sealed cabin 31, and a overturning motor 33 suitable for driving the overturning wheel frame 32 to rotate. The overturning wheel frame 32 is provided with an overturning and conveying assembly line device 35 parallel to the first weighing assembly line mechanism 2 and the second weighing assembly line mechanism 7. At least two tightening devices 37 facing the top of the overturning and conveying assembly line device 35 are arranged on opposite sides of the overturning wheel frame 32 to tighten the bowl body 10 located on the overturning and conveying assembly line device 35. Here, the overturning wheel frame 32 includes two symmetrically arranged circular turntables, and the center positions of the two circular turntables are interspersed with an overturning shaft 34, and the overturning shaft 34 is connected to the overturning motor 33, and the overturning shaft 34 is driven to rotate by the overturning motor 33, thereby driving the circular turntable to rotate. The overturning conveying assembly line device 35 includes a plurality of rollers 351 arranged parallel to the overturning axis 34 along the diameter direction of the circular wheel disc, and rollers are arranged on the rollers 351, and the rollers are driven to rotate by a motor and a chain. Two tightening devices 37 facing the overturning conveying assembly line device 35 are arranged on the two circular turntables, and the tightening devices 37 can be a telescopic cylinder and a top block, and the telescopic cylinder drives the top block to tighten the bowl body 10 located in the overturning conveying assembly line device 35. Two groups of separate tightening devices 37 are arranged here, and the first group of tightening devices 37 can be tightened first after one of the bowl bodies 10 moves into place, and the second group of tightening devices 37 can be controlled to tighten after the second bowl body 10 enters, thereby preventing the problem that the first bowl body 10 has been tightened before the second bowl body 10 enters the overturning conveying assembly line device 35, resulting in the second bowl body 10 being unable to enter. Of course, it should be noted that the tightening device 37 is set according to the number of bowls 10 that the overturning conveying assembly line device 35 can accommodate. For example, when three bowls 10 can be accommodated at one time, three pairs of tightening devices 37 can be set. A fixing rod 321 is also set above the circular turntable to maintain the stability of the connection between the two circular turntables. A stabilizing cylinder 36 is also set on the side of the sealed cabin 31. A stabilizing pressure block is set on the telescopic rod of the stabilizing cylinder 36. The stabilizing pressure block is used to hold the outer side of the circular turntable after the overturning wheel frame 32 is overturned into place, so that the overturning wheel frame 32 maintains the overturning angle after overturning. The stabilizing cylinder 36 can make the overturning wheel frame 32 have better stability after overturning, and reduce the torsional pressure of the overturning motor 33.

[0034] In one embodiment, the pressing devices 37 are arranged above and below the flipping conveyor pipeline device 35. For example, they are defined here as the first pressing device (initially located above the flipping conveyor pipeline device 35) and the second pressing device (initially located below the flipping conveyor pipeline device 35). Meanwhile, a connecting bracket (not shown) is arranged between the pressing devices 37 located on the same circular turntable, and the first pressing device and the second pressing device have a certain moving stroke along a direction perpendicular to the flipping conveyor pipeline device 35 on the circular turntable. For example, the first pressing device and the second pressing device are respectively fixed on the circular turntable through the connecting bracket, and the connecting bracket is connected to a lifting device (not shown) fixed on the circular turntable. When the lifting device drives the connecting bracket to move, the second pressing device located at the bottom of the flipping conveyor pipeline device 35 moves away from the flipping conveyor pipeline device 35, driving the bowl body 10 pressed by it to separate from the flipping conveyor pipeline device 35. At this time, the first pressing device located at the top approaches the flipping conveyor pipeline device 35. When a new bowl body 10 enters from above, then control the first pressing device to press the new bowl body 10; then flip the flipping wheel frame 32 so that the bowl body 10 that has emptied the material and is located below is flipped to the upper position, while the new bowl body 10 filled with material is flipped to the lower position for emptying the material. Then the lifting device moves in the opposite moving direction so that the second pressing device located above descends, making the bowl body 10 that has emptied the material contact the flipping conveyor pipeline device 35, so as to be conveyed out of the flipping and emptying mechanism 3. At this time, the first pressing device located below separates from the flipping conveyor pipeline device 35 for emptying the material. Through the above cycle, each time the flipping and emptying mechanism 3 flips, there is a bowl body 10 emptying the material, and new bowl bodies 10 continuously enter during the emptying process, greatly improving the efficiency; by setting the connecting bracket to cooperate with the lifting device to control the pressing device 37, the bowl body 10 can be separated from the flipping conveyor pipeline when it flips to the lower position, thus not affecting the sending out of the old bowl body 10 above and the entry of the new bowl body 10.

[0035] Combined with Figure 7As shown, the lower part of the tipping and discharging mechanism 3 is connected to the material receiving bin 4 through a collecting hopper 5. The collecting hopper 5 is arranged in a funnel shape and is provided with a butterfly valve 51 at the bottom for controlling the falling of the powder material. The material receiving bin 4 is connected to the collecting hopper 5 and the re-feeding mechanism 6, and is used for recycling the powder material and can convey the powder material to the next process. Here, the re-feeding mechanism 6 includes a vacuum device 61 and a re-feeding bin 62. The vacuum device 61 is connected to the re-feeding bin 62 to generate a vacuum negative pressure in the re-feeding bin 62. The re-feeding bin 62 is communicated to the tipping and discharging mechanism 3 and the first weighing production line mechanism 2 through pipelines, and can also be connected to the first lifting mechanism 8, so as to collect the dust in the air in the tipping and discharging mechanism 3, the first weighing production line mechanism 2 and the first lifting mechanism 8 in the closed space, collect the powder material scattered in the air inside the whole device, and prevent excessive dust from adhering to the internal transmission components. Of course, the re-feeding mechanism 6 can also be communicated to the second weighing production line mechanism 7. A control valve is also arranged between the re-feeding bin 62 and the aggregate bin for controlling the communication between the re-feeding bin 62 and the aggregate bin. Further, a filtering device is also arranged near the control valve, which can preliminarily filter the powder material collected by the re-feeding mechanism 6. The re-feeding mechanism 6 can open the control valve to make the powder material fall into the material receiving bin 4 after collecting a certain amount of powder material.

[0036] In this embodiment, the second weighing production line mechanism 7 is connected between the tipping and discharging mechanism 3 and the second lifting mechanism 9, and a weighing system is arranged inside it for weighing the bowl body 10 after discharging the material again, so that the powder amount poured into the material receiving bin 4 can be known by comparing the weights of the bowl body 10 before and after discharging the material, and it can be used to count the loss ratio of actual production.

[0037] In this embodiment, a control device is also provided. For example, existing industrial control computers and other devices can be used to control the electrical components.

[0038] In this embodiment, in actual production, since the equipment is large in height and volume, a lifting mechanism needs to be set up for height conversion, and at the same time, an installation platform 1 and stairs of a certain height need to be set up to facilitate the operator to reach the specified height for maintenance. Through the solution of the embodiment of the present invention, the efficiency of discharging the material can be effectively improved, and at the same time, the powder material scattered in the air during the discharging process can be collected, which can prevent excessive attachment of the powder material to the transmission mechanism, play a certain protective role for the transmission mechanism, and also improve the collection rate of the powder material.

[0039] It should be understood that the above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention.

[0040] The above introduction of the drawings used in the embodiments only shows some embodiments of the present invention and should not be regarded as a limitation of the scope. For those of ordinary skill in the art, other related drawings can also be obtained based on these drawings without creative efforts.
