Description

Technical Field

[0001] This invention relates to the field of packaging and conveying technology, specifically to a positive pressure conveying device for battery material powder applied to intelligent packaging operations. Background Technology

[0002] When producing batteries using intelligent packaging, the powdered raw materials used in the batteries are also conveyed in conjunction with the intelligent packaging line. Currently, most of the conveying of battery powdered materials is done using a positive pressure pneumatic conveying method.

[0003] Prior art 1 (Chinese patent application number CN202210890554.8, published on September 30, 2022) discloses a positive pressure dense phase conveying device for conveying battery material powder, comprising: a platform, a mounting frame, a controller, a pneumatic compensation mechanism, a first fan, a quantitative feeder, a pneumatic conveyor, a connecting pipe, a storage pipe, a second fan, and a connecting conduit; the pneumatic compensation mechanism is disposed on the top front side of the mounting frame; the first fan is disposed on the top of the mounting frame and located on the rear side of the pneumatic compensation mechanism; the pneumatic conveyor is installed on the top right front of the platform, and the discharge port of the quantitative feeder is connected to the inlet of the pneumatic conveyor. This positive pressure dense phase conveying equipment for battery material powder conveying can perform positive pressure dense phase pneumatic conveying of battery powder during battery processing and production. Without the need to lay or construct new pneumatic conveying pipelines, it can adjust the material conveying path distance, path direction, and conveying volume based on the existing pneumatic conveying system path and equipment, improving the equipment's applicability. Prior art 2 (Chinese patent application number CN202420814893.2, published on December 3, 2024) describes a positive pressure powder conveying equipment, including a feed hopper, a positive pressure sending tank, a receiving hopper, and a sending pipe assembly. The positive pressure sending tank and the feed hopper... The powder feeding hopper is connected to a positive pressure conveying tank for storing and conveying powder. The powder in the positive pressure conveying tank is conveyed to a receiving hopper by compressed gas emitted from the positive pressure conveying tank. A filter is installed on the receiving hopper to allow the gas conveyed from the positive pressure conveying tank to exit, while the powder conveyed from the positive pressure conveying tank to the receiving hopper remains inside. A conveying pipe assembly is located between the positive pressure conveying tank and the receiving hopper. The conveying pipe assembly includes a transparent flexible tube and a mesh tube fitted over the transparent flexible tube. One end of the transparent flexible tube is connected to the positive pressure conveying tank, and the other end is connected to the receiving hopper. The powder positive pressure conveying device of this embodiment can prevent blockages and is easy to observe and operate for unblocking.

[0004] Current conveying devices, when transporting powder materials, rely on pipelines for transport. However, blockages can easily occur at pipeline bends. Blockages can lead to interruptions in feeding, affecting subsequent intelligent packaging operations. Furthermore, the continuous increase in pressure within the pipeline after a blockage poses a safety risk. Conveying needs to be stopped and the blockage addressed, which can disrupt the smooth operation of the subsequent packaging line, reducing its operational stability and efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a positive pressure conveying device for battery material powder applied to intelligent packaging operations, in order to solve the problems mentioned in the background art. When conveying powder materials, the current conveying device is used to complete the conveying through pipelines. However, the pipeline is prone to blockage at bends. After the pipeline is blocked, the feeding will be interrupted, affecting the subsequent intelligent packaging operations. Furthermore, the continuous increase in pressure inside the pipeline after the blockage also poses certain safety risks. After the pipeline is blocked, the conveying needs to be stopped and dealt with, which will also prevent the subsequent packaging line from operating smoothly.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a positive pressure conveying device for battery material powder applied to intelligent packaging operations, comprising a sending chamber, a pressure blower disposed below the sending chamber, a conveying mechanism connected to the right side of the pressure blower, and a receiving hopper connected to the end of the conveying mechanism. The conveying mechanism includes a transverse conveying pipe and a longitudinal conveying pipe, and a connecting frame is disposed between the transverse and longitudinal conveying pipes to connect them. An installation block is disposed at the interface of the transverse and longitudinal conveying pipes, and a conveying channel is opened inside the installation block. The conveying channel connects the internal space of the transverse conveying pipe and the internal space of the longitudinal conveying pipe. A channel switching mechanism is disposed on the outside of the installation block, and the connection channel of the transverse and longitudinal conveying pipes is changed by switching the conveying channel to keep the transverse and longitudinal conveying pipes connected.

[0007] To further optimize this technical solution, a dust collector is installed above the receiving hopper, and an exhaust vent is installed above the dust collector.

[0008] To further optimize this technical solution, a pressure sensor is installed inside the transverse conveying pipe to monitor the pressure inside the transverse conveying pipe. When an increase in pressure is detected and the pipe is blocked, the conveying channel is automatically switched.

[0009] To further optimize this technical solution, the channel switching mechanism includes a support base, a drive base, and a rotating mechanism;

[0010] Support base, fixed to the outside of the transverse conveying pipe and the longitudinal conveying pipe;

[0011] The drive base is connected to the mounting block, and the mounting block is symmetrically arranged about the left and right sides of the drive base. The top view of the combination of the drive base and the mounting block is circular.

[0012] The rotating mechanism is connected to the drive seat and controls the rotation of the drive seat.

[0013] To further optimize this technical solution, the rotating mechanism includes a mounting shaft, a transmission gear, a drive gear, and a first motor;

[0014] The mounting shaft is fixed in the middle of the drive seat, and a rotatable connection is formed between the mounting shaft and the support seat;

[0015] The transmission gear is fixed to the surface of the mounting shaft;

[0016] The drive gear is located outside the transmission gear and meshes with it;

[0017] The first motor is connected to the drive gear to control the rotation of the drive gear.

[0018] To further optimize this technical solution, a movable fitting head is provided at the connection between the transverse conveying pipe, the longitudinal conveying pipe, and the conveying channel, so that the transverse conveying pipe, the longitudinal conveying pipe, and the mounting block are kept in close contact.

[0019] To further optimize this technical solution, the movable bonding head includes a connecting seat, a telescopic tube, a first spring, and a sealing bonding head;

[0020] Connecting seat, fixed to the ends of the transverse conveying pipe and the longitudinal conveying pipe;

[0021] The telescopic tube connects to the connecting seat;

[0022] The first spring, located on the outside of the connecting seat, provides thrust to the telescopic tube;

[0023] The sealing head is connected to the end of the telescopic tube, and the sealing head is attached to the mounting block.

[0024] To further optimize this technical solution, an anti-blocking auxiliary mechanism is installed inside the conveying channel to clear the blockage of products within the conveying channel.

[0025] To further optimize this technical solution, the anti-blocking auxiliary mechanism includes a hollow cavity, a thumping pad, a movable plug, a second spring, a squeezing disc, a control shaft, and a second motor.

[0026] The hollow cavity is located inside the mounting block and is connected to the conveying channel;

[0027] The agitation pad is located at the connection between the hollow cavity and the conveying channel, and the agitation pad is made of elastic material;

[0028] The movable plug is positioned inside the hollow cavity and forms a sliding connection between the hollow cavity and the hollow cavity;

[0029] The second spring is located on the outside of the movable plug to provide a return force for the movable plug;

[0030] The extrusion disc is located inside the drive seat, and the surfaces of the extrusion disc and the movable plug are in contact.

[0031] The control shaft is fixedly connected to the extrusion plate, and the center of the control shaft is offset from the center of the extrusion plate. The control shaft and the drive base are rotatably connected, and the control shaft passes through the mounting shaft.

[0032] The second motor is connected to the control shaft to provide power to the control shaft.

[0033] To further optimize this technical solution, a docking block is fixed to the inner side of the mounting block, and a docking groove that mates with the docking block is opened on the surface of the drive seat. A blocking block is vertically slidably installed inside the docking block. The end of the blocking block has an inclined structure design, and a third spring is fixed to the lower end of the blocking block. The third spring provides thrust to the blocking block. A blocking groove that engages with the blocking block is opened inside the docking groove. An auxiliary rope is fixed below the blocking block. The end of the auxiliary rope is connected to a control plate, and a control head is connected to the outer side of the control plate.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] Switchable conveying channels are installed at the bends of the horizontal and vertical conveying pipes. In case of blockage, the blocked conveying channel can be switched out, allowing the conveying channel to continue working without interrupting the conveying process. This ensures a continuous supply of raw materials to the subsequent intelligent packaging line, improves packaging efficiency, and allows the blocked conveying channel to be cleared after switching.

[0036] The rotation of the drive base can drive the mounting block to rotate, thereby switching the conveying channel. The mounting block and the drive shaft are detachably connected, allowing the mounting block to be removed to convey materials in a blocked conveying channel, enabling it to continue to be used.

[0037] The movable bonding head ensures a tight fit between the transverse and longitudinal conveying pipes and the mounting block, maintaining connection stability as the mounting block moves, preventing material leakage, and improving the stability of conveying channel switching.

[0038] The movement of the movable plug compresses the air inside the hollow cavity, causing the agitator to vibrate and thus vibrate the material in the conveying channel. This prevents the material from getting stuck in the conveying channel, achieving a certain unblocking effect and ensuring the stability of material conveying.

[0039] The eccentric rotation of the extrusion plate can reciprocate to push the movable plug to move. In conjunction with the second spring, the movable plug can reciprocate, thereby providing a reciprocating drive effect for the pulsating pad. Moreover, the connection between the extrusion plate and the movable plug does not affect the subsequent disassembly of the mounting block. Attached Figure Description

The drive gear 17 will drive the transmission gear 16 and the mounting shaft 14 to rotate through meshing with the transmission gear 16, causing the mounting block 12 to rotate and switch the conveying channel 13, so that the blocked conveying channel 13 is turned out. The transverse conveying pipe 3 and the longitudinal conveying pipe 4 are kept in stable contact with the mounting block 12 through the movable bonding head 15.

[0057] Example 3: Based on Example 2, an anti-blocking auxiliary mechanism is disclosed inside the conveying channel 13 to clear the product inside the conveying channel 13. The anti-blocking auxiliary mechanism includes a hollow cavity 19, an agitating pad 20, a movable plug 21, a second spring 22, a pressing disc 23, a control shaft 24, and a second motor 25. The hollow cavity 19 is located inside the mounting block 12 and is connected to the conveying channel 13. The agitating pad 20 is located at the connection between the hollow cavity 19 and the conveying channel 13 and is made of an elastic material. The movable plug 21 is located inside the hollow cavity 19 and forms a sliding connection with the hollow cavity 19.

[0058] During the conveying operation, the control shaft 24 driven by the second motor 25 can drive the extrusion disc 23 to rotate eccentrically.

When the movable plug 21 moves, the pressure in the hollow cavity 19 will change, thereby deforming the agitator 20 and shaking the product in the conveying channel 13 to prevent it from getting blocked at the bend. The mounting block 12 can be removed from the drive seat 11 for maintenance and replacement. When removing the mounting block 12, the control head 3201 can be pulled to move the auxiliary rope 31 through the control plate 32, which will pull the blocking block 28 to move and disconnect the blocking block 28 from the blocking groove 29.
