Description

Technical Field

[0001] This utility model relates to the field of ball mill jar technology, specifically to a quick-loading and unloading ball mill jar fixing device. Background Technology

[0002] Planetary ball mills, widely used in scientific research experiments, are commonly used equipment for the uniform mixing of raw materials and the grinding of particles. During use, the grinding jars of a ball mill are frequently installed and disassembled.

[0003] Existing patent CN113368969A discloses a laboratory planetary ball mill jar device. A ball mill jar body is placed in a jar clamp, followed by a sample and grinding balls of suitable material and size. A jar lid with a grinding blade is then placed on top. A carrying pole with a swivel handle and a pressure plate is then mounted. Rotating the swivel handle causes the lead screw to exert sufficient reaction force through the screw hole fulcrum to press the pressure plate firmly. Finally, a locking nut is tightened to prevent loosening. The existing technical problems are as follows: Currently, the fixing device uses a swivel handle, lead screw, and carrying pole to fix the ball mill jar in the jar clamp. The method of fixing and removing the end cover of the ball mill jar by rotating the lead screw and engaging the slot generates axial force that drives the ball mill's rotating shaft, making installation inconvenient. Furthermore, during installation and disassembly, using significant force to tighten or loosen the lead screw during repeated operations can easily cause misalignment and jamming, making disassembly difficult and reducing the lifespan of the support frame. Utility Model Content

[0004] The purpose of this utility model is to provide a quick loading and unloading device for fixing ball mill jars.

[0005] This utility model is implemented by the following technical solution: a quick loading and unloading ball mill jar fixing device, which includes a pressure block, a support column, a side connecting frame, a top plate, a base, a guide device, a limiting block, and a connecting block;

[0006] The support column is fixed at the top center of the pressure block, and the side connecting frame is provided on both sides of the support column.

[0007] The side connecting frame includes the base and the guide device. Two sets of guide devices are fixed on the top end face of the base near the support column. A top plate is fixed between the top ends of the two sets of guide devices. The limiting block and the connecting block are slidably arranged between the two sets of guide devices from top to bottom.

[0008] The connecting block extends to the outside of the guide device and is fixedly connected to the bottom outer wall of the support column. A first fastening bolt passes through the connecting block and the guide devices on both sides.

[0009] The limiting block extends to the outside of the guide device and movably abuts against the top end face of the support column. A second fastening bolt passes through the limiting block and the guide devices on both sides.

[0010] Furthermore, the guiding device includes two vertically arranged guide rods, the bottom end of which is fixedly connected to the top end face of the base, and the top end of which is fixedly connected to the bottom end face of the top plate. The limiting block and the connecting block are respectively provided with sliding grooves that match the guide rods on both sides, and the limiting block and the connecting block are slidably connected to the guide rods through the sliding grooves.

[0011] Furthermore, a slot is provided on the top end face of the base away from the support column, and the slot matches the slot interface of the ball mill jar clamp.

[0012] Advantages of this utility model:

[0013] With the cooperation of the first and second fastening bolts, the support column and the ball mill jar clamp are kept stationary by the limiting block and the connecting block. Through the two reinforcement actions, the stability of the ball mill jar is increased.

[0014] Since the direction of force is perpendicular to the rotation direction of the ball mill when the first and second fastening bolts are loosened or tightened, the inconvenience of disassembly caused by the axial force on the ball mill shaft during loading and unloading is reduced; the support column and the side connecting frame can be adjusted up and down by loosening or tightening the first and second fastening bolts, which solves the problem of thread damage caused by the fixing or disassembly of the screw in the prior art, and improves the ease of use and stability of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-4 As shown, the quick loading and unloading ball mill jar fixing device includes a pressure block 1, a support column 2, a side connecting frame 3, a top plate 6, a base 4, a guide device 5, a limiting block 7, and a connecting block 8.

[0023] A support column 2 is fixed at the top center of the pressure block 1, and side connecting frames 3 are provided on both sides of the support column 2.

[0024] The side connecting frame 3 includes a base 4 and a guide device 5. Two sets of guide devices 5 are fixed on the top end face of the base 4 near the support column 2. A top plate 6 is fixed between the top ends of the two sets of guide devices 5. A limiting block 7 and a connecting block 8 are slidably provided between the two sets of guide devices 5 from top to bottom.

[0025] The connecting block 8 extends to the outside of the guide device 5 and is fixedly connected to the support column 2. A first fastening bolt 9 passes through the connecting block 8 and the two guide devices 5. The limiting block 7 extends to the outside of the guide device 5 and movably abuts against the top end face of the support column 2. A second fastening bolt 10 passes through the limiting block 7 and the two guide devices 5. In this embodiment, the limiting block 7 is wedge-shaped.

[0026] With the cooperation of the first fastening bolt 9 and the second fastening bolt 10, the support column 2 and the ball mill jar clamp are kept stationary by the limiting block 7 and the connecting block 8, which increases the stability of the ball mill jar. Since the direction of force is perpendicular to the rotation direction of the ball mill when the first fastening bolt 9 and the second fastening bolt 10 are loosened or tightened, the inconvenience of disassembly caused by the axial force of the ball mill shaft during loading and unloading is reduced. The up and down adjustment of the support column 2 and the side connecting frame 3 can be achieved by loosening or tightening the first fastening bolt 9 and the second fastening bolt 10, which solves the problem of thread damage caused during the fixing or disassembly of the screw in the prior art, and improves the ease of use and stability of the device.

[0027] The guiding device 5 includes two vertically arranged guide rods 5.1. The bottom end of the guide rod 5.1 is fixedly connected to the top end face of the base 4, and the top end of the guide rod 5.1 is fixedly connected to the bottom end face of the top plate 6. The limiting block 7 and the connecting block 8 are respectively provided with sliding grooves 11 that match the guide rods 5.1. The limiting block 7 and the connecting block 8 are slidably connected to the guide rods 5.1 through the sliding grooves 11.

[0028] A slot 12 is provided on the top end face of the base 4 away from the support column 2. The slot 12 matches the locking interface of the ball mill jar clamp. The slot 12 has a limiting function to prevent the base from moving left and right at the locking interface of the ball mill jar clamp.

[0029] The specific operation process of this embodiment is as follows:

[0030] Place the grinding jar inside the grinding jar clamp, and place the device on top of the grinding jar so that the pressure block 1 of the device is positioned above the end cap of the grinding jar. Then, according to the position of the clamping interface of the grinding jar clamp, loosen the first fastening bolt 9 to allow the side connecting frame 3 to slide up and down along the connecting block 8. Adjust the position of the base 4 of the side connecting frame 3 so that the base 4 can be clamped into the clamping interface of the grinding jar clamp. Then tighten the first fastening bolt 9 so that the side connecting frame 3 and the connecting block 8 remain relatively stationary, which further ensures that the positions of the side connecting frame 3 and the support column 2 remain relatively stationary, thus providing a primary reinforcement function.

[0031] Loosen the second fastening bolt 10 so that the bottom end of the limiting block 7 abuts against the top end face of the support column 2, and tighten the second fastening bolt 10. The function of the limiting block 7 is to restrict the support column 2 from moving upward during the test, and it has the function of secondary reinforcement.

[0032] The planetary ball mill can now be started.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
