Description

Technical Field

[0001] This invention relates to vibrating feeder technology, and more specifically, to a maintenance-free feeding gate for a vibrating feeder and its method of use. Background Technology

[0002] Currently, the types of feed gates suitable for vibrating feeders include rack and pinion gates, bar gates, and slide gates. These conventional feed gates are not suitable for applications involving highly corrosive, highly viscous, or easily agglomerated materials, mainly for the following reasons:

[0003] (1) The material is sticky and easily clumps together, which can jam the operating mechanism. Cleaning the clumps is troublesome and poses a potential installation hazard.

[0004] (2) The raw materials are complex and irregular in size. The normal particle size is 4~30mm, and the abnormal size is 300mm, making it difficult to discharge and remove the lumps.

[0005] (3) Using rack and pinion gate: The rack is prone to material accumulation. When the rack is full, the guide rail will also accumulate material, and it will not be able to open. Regular cleaning is required, and the rack and guide rail need to be lubricated regularly.

[0006] (4) If the gate is jammed, the handwheel cannot be moved at all and the screw rod will bend.

[0007] In summary, existing material gates are prone to corrosion and jamming of drive components, and materials are prone to adhesion, bridging, and clumping, resulting in uneven material distribution, difficulty in precise flow control, and consequently, unstable equipment load and large fluctuations in operating current. Summary of the Invention

[0008] To address the shortcomings of existing technologies, the purpose of this invention is to provide a maintenance-free feeding gate for vibrating feeders and its usage method. This specialized feeding gate is suitable for conditions involving strong corrosion, high viscosity, and easy agglomeration, thereby reducing equipment failures and jamming problems at the source. At the same time, it ensures flexible and convenient opening adjustment, strong flow controllability, and stable equipment operation.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] The first aspect of the present invention provides a maintenance-free feeding gate for a vibrating feeder, comprising a traction channel steel, a feeding gate body, and a four-bar linkage connected to the feeding gate body;

[0011] The four-bar linkage includes a right four-bar linkage and a left four-bar linkage symmetrically arranged on both sides of the feed gate body;

[0012] Two traction channel steels are provided and symmetrically fixed to the wall panel, corresponding to the positions of the right four-bar linkage and the left four-bar linkage;

[0013] Both the right four-bar linkage and the left four-bar linkage include a first link, a second link, a shoulder plate, and a drive rod;

[0014] The lower end of the first connecting rod is movably connected to the lower end of the second connecting rod and fixed to the wall panel;

[0015] The upper end of the first connecting rod is movably connected to the lower end of the driving rod;

[0016] The upper end of the second connecting rod is movably connected to the lower end of the shoulder plate;

[0017] The upper end of the shoulder plate is movably connected to the drive rod;

[0018] The shoulder plate is fixed to the material discharge gate body;

[0019] The upper end of the drive rod is connected to the drive device;

[0020] The traction channel steel provides support for the drive device.

[0021] Preferably, pin holes are provided at both ends of the first connecting rod and at both ends of the second connecting rod.

[0022] Both ends of the drive rod and near the upper end of the drive rod are provided with pin holes;

[0023] The outer side of the shoulder plate is provided with a connecting plate, and both ends of the connecting plate are provided with bolt holes;

[0024] A pin is installed in the pin hole to achieve a movable connection.

[0025] Preferably, the end of the pin connecting the lower end of the first link and the lower end of the second link is fixed to the wall panel.

[0026] Preferably, bolt holes are provided on the surface of the shoulder plate;

[0027] Bolts are installed in the bolt holes to fix the feed gate body.

[0028] Preferably, the upper end of the drive rod is also provided with a hook.

[0029] The second aspect of the present invention provides a method for using the maintenance-free feeding gate for a vibrating feeder based on the first aspect of the present invention;

[0030] After the material conveying system is started, the gate adjustment module performs a self-test and feeds back the self-test signal to the central control system. If the self-test signal is normal, the central control system is allowed to start the material conveying program, that is, the gate adjustment module controls the drive device to start.

[0031] The central control system sets the conveying capacity of the belt conveyor in the material conveying system. After receiving the instruction, the gate adjustment module automatically and gradually adjusts the drive device so that the discharge gate body forms the corresponding opening degree.

[0032] During adjustment, the material conveying system continuously monitors the current trend and belt conveying flow rate of the belt conveyor;

[0033] When the central control system issues a stop command for the material conveying system, the gate adjustment module gradually shuts down the drive device. When the conveying flow rate is detected as 0, the drive device drives the discharge gate body to close in place, and the material conveying system stops.

[0034] Preferably, when the material conveying system continuously monitors the conveyor belt, if an abnormal downstream receiving current is detected, the drive device drives the discharge gate body to automatically close; if an abnormal current is detected, the discharge vibration mechanism is shut down; if an alarm is detected by the gate adjustment module, the central control system receives the alarm, and the inspection personnel go to the site to check and confirm.

[0035] The maintenance-free feeding gate for a vibrating feeder and its usage method provided by this invention have the following beneficial effects:

[0036] (1) Simplified and reliable structure

[0037] The simplified internal structure design has fewer parts and a simpler transmission, making the whole machine lightweight and compact. It allows for flexible installation and layout, and reduces the wear and tear on parts, thereby reducing the probability of failure from the source and making the equipment more stable.

[0038] (2) Long-lasting maintenance-free design

[0039] The joints are designed to be maintenance-free, replacing bearings and bearing housings. They do not accumulate material or rust, and require no maintenance. No regular maintenance or replacement of parts is needed throughout the process, saving on daily inspections, maintenance consumables and labor hours, resulting in lower overall costs in the long run.

[0040] (3) Zero learning curve and extremely simple operation

[0041] The control logic is straightforward and clear, and the operation steps are simplified. No complicated learning or professional skills are required. All operations such as starting, stopping, and reversing can be completed in just a few simple steps, which reduces the likelihood of operational errors and greatly improves the smoothness of operation.

[0042] (4) Multiple drivers are available to adapt to all scenarios

[0043] It offers three drive options: manual, pneumatic, and electric. The manual version requires no energy and can be used anytime, anywhere; the pneumatic version has sufficient power and fast response, suitable for continuous factory production; and the electric version is easy to integrate into automated production lines, offering precise and controllable operation. The main body of the machine is universal, and the drive type can be switched as needed to adapt to various production, outdoor, and automated working conditions. Attached Figure Description

[0050] Combination Figures 1 to 5 As shown, the present invention provides a maintenance-free feeding gate for a vibrating feeder, including a feeding gate body 1 and a four-bar linkage connected to the feeding gate body 1.

[0051] The four-bar linkage includes a right four-bar linkage 2 and a left four-bar linkage 3 symmetrically arranged on both sides of the feed gate body 1.

[0052] Two traction channel steels 17 are set and symmetrically fixed to the wall panel, corresponding to the positions of the right four-bar linkage 2 and the left four-bar linkage 3.

[0053] Both the right four-bar linkage 2 and the left four-bar linkage 3 include a first link 4, a second link 5, a shoulder plate 6, and a drive rod 7.

[0054] The lower end of the first link 4 and the lower end of the second link 5 are movably connected by a pin 8, and the end of the pin 8 is also fixed to the wall plate of the vibrating feeder.

[0055] The upper end of the first link 4 is movably connected to the lower end of the drive rod 7 via a pin 9.

[0056] The upper end of the second link 5 is movably connected to the lower end of the shoulder plate 6 via a pin 10.

[0057] The upper end of the shoulder plate 6 is movably connected to the drive rod 7 near the upper end via a pin 11.

[0058] The shoulder plate 6 is fixed to the feed gate body 1 by bolts.

[0059] The upper end of drive rod 7 is connected to the drive device;

[0060] Traction channel steel 17 provides a dedicated force support point for the drive unit.

[0061] Both ends of the first link 4 and both ends of the second link 5 are provided with pin holes 12 for placing the corresponding pins.

[0062] Both ends of the drive rod 7 and near the upper end of the drive rod 7 are provided with pin holes 13 for placing the corresponding pins.

[0063] A connecting plate 14 is provided on the outer side of the shoulder plate 6. Both ends of the connecting plate 14 are provided with pin holes 15 for placing the corresponding pins.

[0064] Bolt holes 16 are provided on the surface of the shoulder plate 6, and bolts are installed in the bolt holes 16 to achieve a fixed connection with the feed gate body 1.

[0065] A hook 18 is also provided at the upper end of the drive rod 7 to increase the force angle between the drive rod 7 and the drive device, avoid the drive force deviation, and increase resistance.

[0066] The present invention also provides a method for using the maintenance-free feeding gate based on the present invention, as detailed below:

[0067] After the material conveying system is started, the gate adjustment module performs a self-test and feeds back the self-test signal to the central control system. If the self-test signal is normal, the central control system is allowed to start the material conveying program, that is, the gate adjustment module controls the drive device to start.

[0068] The central control system sets the conveying capacity of the belt conveyor in the material conveying system. After receiving the instruction, the gate adjustment module automatically and gradually adjusts the drive device to make the discharge gate body form the corresponding opening degree.

[0069] During adjustment, the material conveying system continuously monitors the current trend and belt conveying flow rate of the belt conveyor;

[0070] When the material conveying system stops, after the central control system issues a stop material conveying command, the gate adjustment module gradually shuts down the drive device. When the conveying flow rate is detected as 0, the drive device drives the discharge gate body to close in place, and the material conveying system stops.

[0071] When the conveyor system continuously monitors the conveyor belt, if an abnormal downstream receiving current is detected, the drive device will automatically close the discharge gate body; if an abnormal current is detected, the discharge vibration mechanism will be shut down; if an alarm is detected in the gate adjustment module, the central control system will receive the alarm, and the inspection personnel will go to the site to check and confirm.

[0072] The gate adjustment module communicates wirelessly with the central control system in real time. It receives instructions from the central control system to adjust the opening of the maintenance-free feeding gate and provides feedback on the position and status (over-torque) of the gate body. The central control system sets the material feed rate for downstream equipment, and the gate adjuster automatically adjusts accordingly. The gate adjustment module checks its communication status with the central control system every 5 seconds. If a disconnection is detected, it immediately and automatically closes the maintenance-free feeding gate and issues an alarm. The gate adjustment module is dustproof, waterproof, reliable, and durable.

Any variations or modifications to the above embodiments that are within the spirit and essence of the present invention will fall within the scope of the claims of the present invention.
