Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of rod mill rod feeding technology, and more specifically, to a rapid rod feeding device for a rod mill. Background Technology

[0002] A rod mill is a widely used grinding equipment in the sand making industry. During operation, the cylinder is filled with an appropriate amount of grinding media - steel rods. The fed material is crushed and ground after being impacted and ground by the steel rods. The ground material is discharged through the discharge port. As the steel rods wear down, the rod mill needs to be replenished with steel rods in a timely manner. At this time, a rod adding device is needed. The rod adding device is a facility used to add rods into the rod mill. In the existing technology, the steel rods of the rod adding device are usually added by hoisting the steel rods to a simple support roller conveyor and pushing them into the rod adding cylinder of the rod mill from the feed port by manual pushing. This method has a low degree of automation and requires a lot of time and manpower. This method of adding rods has the problems of long downtime of the rod mill and low working efficiency. Utility Model Content

The two sprockets on the first rotating shaft located in the middle are staggered, and the corresponding two sprockets are connected by the chain drive.

[0009] As a preferred embodiment of the rapid rod feeding device for a rod mill according to this utility model, in order to achieve buffered feeding of the lifted rod material, two sets of buffer feeding mechanisms are installed on the upper side of the main support.

A protective shell 8 is installed on one side of the main support 1, covering the outside of the transmission mechanism. The protective shell 8 is provided with a drive mechanism. Multiple first rotating shafts 6 are driven by a forward and reverse rotating motor. Multiple second mounting seats 9 are mounted on the upper side of the main support 1. A second rotating shaft 10 is rotatably mounted inside each second mounting seat 9. An upper steel top plate 11 is mounted on the second rotating shaft 10. A bar material drop chute is formed on one side of the upper steel top plate 11. An inclined surface is provided on the side of the upper steel top plate 11 near the bar material placement support 4, and this inclined surface is connected to the bar material drop chute. The inclined surface on the upper steel top plate 11 allows the bar material, after being lifted by the upper steel top plate 11, to automatically roll into the bar material drop chute. An adjustment mechanism for driving the second rotating shafts 10 is provided on the main support 1. When the second rotating shaft 10 rotates under the drive of the adjustment mechanism, it can synchronously drive the upper steel top plate 11 to deflect around the second rotating shaft 10 as the center. The adjustment mechanism includes a T-shaped transmission seat 101, a transmission arm 102, a linkage cantilever 103 and a hydraulic cylinder 104. The T-shaped transmission seat 101 is installed on one of the two ends of the second rotating shaft 10. The transmission arm 102 is sleeved on the T-shaped transmission seat 101. The linkage cantilever 103 is hinged to the outside of the two transmission arms 102. The hydraulic cylinder 104 is installed on the main support 1 through the hinge seat. The telescopic end of the hydraulic cylinder 104 is connected to the linkage cantilever 103 through the connecting column. like Figure 1 and Figure 4As shown, two sets of buffer feeding mechanisms are installed on the upper side of the main support 1. The buffer feeding mechanism includes a buffer assembly and a receiving assembly. The buffer assembly includes a column 301, a limiting rod 302, a buffer seat 303, and a spring 304. Multiple columns 301 are installed on the upper side of the main support 1. The limiting rod 302 is installed in the middle of the inner bottom wall of the column 301. The buffer seat 303 is sleeved on the limiting rod 302 and can move along the limiting rod 302. Two buffer seats 303 are connected by a connecting plate.

The arc-shaped receiving tray 402 is installed on the top of the support rod 401 and moves synchronously with the support rod 401. Multiple ball bearings 403 are rolled on the upper side of the arc-shaped receiving tray 402. A movable opening is provided on the outer side of the column 301. The width of the movable opening is adapted to the width of the connecting plate. When the impact force received by the arc-shaped receiving tray 402 is buffered, the connecting plate moves inside the movable opening.

[0023] Working principle: The bar feeding device is used in the factory. Workers move the device to one side of the bar mill using the moving wheels 2, ensuring the conveying rollers 7 in the device and the bar feed inlet of the mill face the same direction. Then, the electrical components inside the device are connected to the factory's power supply via power lines. The device is then tested to ensure proper operation. When bar feed needs to be added to the bar mill, the forward and reverse motors are started. These motors drive multiple first rotating shafts 6 to rotate synchronously via a transmission mechanism. These first rotating shafts 6 then drive multiple conveying rollers 7 to rotate synchronously. Next, workers use a crane to place multiple bars onto the bar feed tray 4 in an orderly manner. After placement, the hydraulic cylinder 104 is activated, extending its telescopic end and moving the cantilever 103 in conjunction with the cylinder. The linkage cantilever 103 drives the second rotating shaft 10 to rotate through the transmission arm 102 and the T-shaped transmission seat 101. The second rotating shaft 10 drives the upper steel top plate 11 to deflect upward. During the deflection of the upper steel top plate 11, the bar at the bottom of the bar placement tray 4 is slowly lifted. After being lifted, the bar rolls down the inclined surface into the bar drop chute and onto the arc-shaped receiving tray 402. Then, the extension end of the hydraulic cylinder 104 is controlled to retract, driving the linkage cantilever 103 to move. The linkage cantilever 103 drives the second rotating shaft 10 to rotate in the opposite direction through the transmission arm 102 and the T-shaped transmission seat 101. The second rotating shaft 10 drives the upper steel top plate 11 to deflect downward. During the deflection of the upper steel top plate 11, the bar in the bar drop chute slowly falls onto the conveying roller 7. The conveying roller 7 conveys the bar into the inside of the bar mill, realizing the rapid addition of bar stock.
