It effectively regulates blood sugar levels by reducing glucose production in the liver and improving the body's sensitivity to insulin. In the production process of metformin hydrochloride sustained-release tablets, the raw materials usually need to be crushed. The purpose of the crushing process is to adjust the size of the raw material particles to an appropriate range to ensure uniform mixing, smooth tableting and effective release of the drug. The hammer mill has a high crushing efficiency and can crush the raw materials to the required particle size range; it can adapt to raw materials of different hardness; and it is relatively simple to operate and cost-effective.

[0023] In this embodiment, when in use, the drive system 103, the hydraulic rod 204 and the control system 102 are electrically connected, such as Figure 8As shown, two marking grooves 304 that can form a ring are grouped into seven groups, four sealing holes 305 close to a group of marking grooves 304 are grouped into seven groups, four vertical insertion holes 214 are grouped into seven groups, seven groups of insertion holes 214 are respectively aligned with the seven groups of sealing holes 305, vertical L-shaped rods 215 are grouped into seven groups, four horizontal fixing plates 213 are grouped into seven groups, four connecting rods 317 inside each adjusting groove 323 are grouped into seven groups, two connecting grooves 315 are provided near the edge of one side of the outer surface of the seven crushing hammers 302, fourteen connecting grooves 315 are provided in total, The inner walls of both sides of each connecting groove 315 are connected to the sealing gasket 308. The two sealing gaskets 308 in the same connecting groove 315 are in contact with each other. A connecting strip 314 is movably embedded between the two sealing gaskets 308. The position of the connecting strip 314 will separate the two sealing gaskets 308. The parts of the two sealing gaskets 308 that are not in contact with the connecting strip 314 will contact each other. The sealing gaskets 308 have a certain elasticity, which facilitates the connection strip 314 to rotate between the two sealing gaskets 308. An arrow mark for rotation adjustment is set on the outer surface of one side of each crushing hammer 302, and an indicating arrow is set on each rotating block 313. Figure 8 As shown, it is convenient for the staff to adjust the position of the rotating block 313. Two fixing plates 213 are set on the outer surface of each L-shaped rod 215. The L-shaped rod 215 contacts the fixing plate 213 on the left side. Fig.10First, align the two positioning columns 311 inside the crushing hammer 302 with the two positioning grooves 303 and slide them in, so that the crushing hammer 302 is slidably sleeved on the outer surface of the rotor body 301, and the side with the arrow mark faces the left, and the seven crushing hammers 302 are sequentially sleeved on the outer surface of the rotor body 301, and then the box cover 201 is kept in a vertical state, and the positioning hole 203 is aligned with the positioning rod 108, at this time, the drum 207 will be aligned with one end of the rotor body 301, and then the box cover 201 is moved and installed on the outer surface of the crushing box 104, and fastened with bolts, and at the same time, the drum 207 is pushed into the rotor body 301, and then the positions of the seven crushing hammers 302 are adjusted through the mounting holes 111, and according to the positions of the seven groups of marking grooves 304, respectively The seven crushing hammers 302 are slid to move to the seven groups of marking grooves 304 respectively. The seven groups of connecting rods 317 are aligned with the positions of the seven groups of sealing holes 305 and the seven groups of insertion holes 214 respectively. Then, the seven rotating blocks 313 are rotated in sequence in the direction of the arrows on the side of the crushing hammers 302. The rotation of the rotating blocks 313 drives the two connected connecting strips 314 to rotate internally in the corresponding sealing gaskets 308, thereby separating the two contacting sealing gaskets 308, and the two sealing gaskets 308 that are not in contact with the connecting strips 314 are fitted together again under their own elasticity (the connecting strips 314 and the sealing gaskets 308 are in close contact, and an external rotation force is required to drive the connecting strips 314 to rotate). Then, the annular plate 307 is driven to adjust The groove 323 rotates inside, further driving the two arc blocks 309 to rotate at one end of the four connecting rods 317 at the same time, so that the connecting rods 317 move from the deep inside the arc block 309 to the shallow part, thereby pushing the four connecting rods 317 to pass through the moving hole 322, the sealing ring 306 and the plug hole 214 to move toward the moving rod 205, and driving the connecting block 316 to move together, and at the same time the spring 318 is squeezed and contracted together. When the rotating block 313 can no longer rotate, the connecting rod 317 contacts the shallowest part of the arc block 309, one end of the connecting rod 317 moves to the inside of the rotating drum 207, the clamping hole 321 moves to the L-shaped rod 215, and the spring 318 is squeezed and completely contracted together, thereby pre-installing the crushing hammer 302 on the rotating drum. The outer surface of the sub-body 301 is repeated to pre-install other crushing hammers 302, and then the sealing cover 106 is installed at the mounting hole 111, and the mounting hole 111 is sealed by the sealing plate 109, which does not affect the subsequent crushing process. Finally, the hydraulic rod 204 is started, and the moving rod 205 is pulled to move to the left inside the rotating drum 207 and the support ring 208, and the fixing plate 213 and the fixing rod 216 are driven to move together, so that the L-shaped rod 215 is separated from the fixing plate 213 on the left, and gradually contacts with the fixing plate 213 on the right, so that the L-shaped rod 215 is driven to move on the outer surface of the support rod 217 under the movement of the fixing plate 213. When the hydraulic rod 204 is automatically closed, the L-shaped rod 215 is just inserted into the clamping hole 321.The right fixing plate 213 limits the L-shaped rod 215, and the L-shaped rod 215 limits the connecting rod 317, thereby limiting the crushing hammer 302. Under the cooperation of the fixing component 2 and the pre-installation component 3, multiple hammer heads can be quickly installed and fixed, and there is no need to use bolts to install them one by one, so as to avoid the subsequent bolts being loosened and falling off due to impact force, thereby causing the hammer head to loosen. This solves the problem that during the use of the raw material crushing device for the production of metformin hydrochloride sustained-release tablets, the hammer head is repeatedly hit by the material and vibrates. This continuous impact force will gradually loosen the bolts, further causing the hammer head to loosen, increasing the probability of the hammer head colliding with other components, affecting the service life of the equipment, and also increasing the probability of dust entering the bolt connection, affecting the tightening effect of the bolts, and aggravating the problem of the degree of looseness of the hammer head.

[0024] Embodiment 2: Figure 1-Figure 6 As shown, it includes a crushing component 1, which is used to crush the raw material.

[0025] In this embodiment, when in use, after the fixing of the crushing hammer 302 is completed by the fixing component 2 and the pre-installation component 3, the raw material of the metformin hydrochloride sustained-release tablet is transported to the crushing box 104 through the feeding pipe 105, and the rotor body 301 is started to rotate by the driving system 103, which further drives the multiple crushing hammers 302 to rotate, and the raw material enters the crushing box 104 and is crushed by the impact of the high-speed rotating crushing hammers 302. The crushed raw material obtains kinetic energy from the crushing hammers 302 and rushes toward the lining baffle and the screen 110 of the crushing box 104 at high speed. At the same time, the materials collide with each other and are crushed multiple times. The materials smaller than the gap of the screen 110 are discharged from the gap and fall into the lower hopper 107. Some larger materials are again impacted by the crushing hammers 302 on the screen 110 and crushed, thereby obtaining products of the required particle size, and completing the crushing processing of the raw materials. When the rotor body 301 rotates, it drives the crushing hammer 302 to rotate, and drives the arc plate 310 inside the adjustment groove 323 to rotate, and further drives the connecting rod 317 to rotate together, and drives the rotating drum 207 to rotate together through the connecting rod 317, and at the same time drives the support rod 217 and the L-shaped rod 215 to rotate, thereby driving the fixing rod 216 to rotate inside the annular groove 218 without affecting the crushing process of the raw materials. Before using the fixing assembly 2, the support plate 209 is limited by the limit plate 206 and the limit rod 211, thereby limiting the rotating drum 207 to prevent the rotating drum 207 from automatically rotating when the box cover 201 is installed, causing the plug hole 214 to rotate and unable to be relative to the sealing hole 305, resulting in the connecting rod 317 being unable to enter the rotating drum 207, affecting the fixed installation of the crushing hammer 302. When the hydraulic rod 204 pulls the moving rod 205 to move to the left, it will drive the limit plate 206 to move together, pulling the limit rod 211 out of the limit groove 212, and will not affect the subsequent rotation of the rotating drum 207.

[0026] The method of use and working principle of the present invention are as follows: first, the two positioning columns 311 inside the crushing hammer 302 are aligned with the two positioning grooves 303 and slid in, so that the crushing hammer 302 is slidably sleeved on the outer surface of the rotor body 301, and the seven crushing hammers 302 are sequentially sleeved on the outer surface of the rotor body 301, and then the box cover 201 is kept in a vertical state, and the positioning hole 203 is aligned with the positioning rod 108. At this time, the drum 207 will be aligned with one end of the rotor body 301, and then the box cover 201 is moved and installed on the outer surface of the crushing box 104 and fastened by bolts. At the same time, the drum 207 is pushed into the rotor body 301, and then the positions of the seven crushing hammers 302 are adjusted through the mounting holes 111, and the seven groups of marking grooves 304 are slid respectively according to the positions of the seven groups of marking grooves 304. The pulverizing hammer 302 is moved to the seven groups of marking grooves 304 respectively. The seven groups of connecting rods 317 are aligned with the positions of the seven groups of sealing holes 305 and the seven groups of insertion holes 214 respectively. Then, the seven rotating blocks 313 are rotated in sequence in the direction of the arrows on the side of the pulverizing hammer 302. The rotation of the rotating blocks 313 drives the two connected connecting strips 314 to rotate inside the corresponding sealing gaskets 308, thereby separating the two contacting sealing gaskets 308, and the two sealing gaskets 308 that are not in contact with the connecting strips 314 are fitted together again under their own elasticity, and then the annular plate 307 is driven to rotate inside the adjusting groove 323, and the two arc blocks 309 are further driven to rotate at one end of the four connecting rods 317 at the same time, so that the connecting rods 317 are moved from the arc The deep part of the block 309 moves to the shallow part, thereby pushing the four connecting rods 317 through the moving hole 322, the sealing ring 306 and the socket 214 to move toward the moving rod 205, and driving the connecting block 316 to move together. At the same time, the spring 318 is squeezed and contracted together. When the rotating block 313 cannot continue to rotate, the connecting rod 317 contacts the shallowest part of the arc block 309, and one end of the connecting rod 317 moves to the inside of the rotating drum 207. The clamping hole 321 moves to the L-shaped rod 215, and the spring 318 is squeezed and completely contracted together, thereby pre-installing the crushing hammer 302 on the outer surface of the rotor body 301. Repeat the above operation to pre-install other crushing hammers 302, and then install the sealing cover 106 at the installation hole 111. The mounting hole 111 is sealed through the sealing plate 109, and finally the hydraulic rod 204 is started to pull the moving rod 205 to move to the left, and drive the fixing plate 213 and the fixing rod 216 to move together, so that the L-shaped rod 215 is separated from the fixing plate 213 on the left, and gradually contacts with the fixing plate 213 on the right, so that the L-shaped rod 215 is driven to move on the outer surface of the support rod 217 under the movement of the fixing plate 213. When the hydraulic rod 204 is automatically closed, the L-shaped rod 215 is just inserted into the clamping hole 321, and the right fixing plate 213 limits the L-shaped rod 215, and the L-shaped rod 215 limits the connecting rod 317, so as to limit the crushing hammer 302. Under the cooperation of the fixing component 2 and the pre-installed component 3, multiple hammer heads can be quickly installed and fixed.There is no need to install them one by one with bolts, so as to avoid the subsequent bolts being loosened and falling off due to impact force, thereby causing the hammer head to loosen. The raw materials of metformin hydrochloride sustained-release tablets are transported to the crushing box 104 through the feeding pipe 105, and the rotor body 301 is started to rotate through the driving system 103, which further drives the multiple crushing hammers 302 to rotate. The raw materials enter the crushing box 104 and are crushed by the impact of the high-speed rotating crushing hammers 302. The crushed raw materials obtain kinetic energy from the crushing hammers 302 and rush toward the lining baffle and screen 110 of the crushing box 104 at high speed. At the same time, the materials collide with each other and are crushed multiple times. The materials smaller than the gap of the screen 110 are discharged from the gap and fall into the lower hopper 107. Some larger materials are crushed again by the impact of the crushing hammers 302 on the screen 110, so as to obtain products of the required particle size, and complete the crushing processing of the raw materials. When the rotor body 301 rotates, it drives the crushing hammer 302 to rotate, and drives the arc plate 310 inside the adjustment groove 323 to rotate, and further drives the connecting rod 317 to rotate together, and drives the rotating drum 207 to rotate together through the connecting rod 317, and at the same time drives the support rod 217 and the L-shaped rod 215 to rotate, thereby driving the fixing rod 216 to rotate inside the annular groove 218 without affecting the crushing process of the raw materials. Before the fixing assembly 2 is used, the support plate 209 is limited by the limiting plate 206 and the limiting rod 211, thereby limiting the drum 207, to prevent the drum 207 from automatically rotating when the box cover 201 is installed, causing the plug hole 214 to rotate and unable to be opposite to the sealing hole 305, resulting in the connection rod 317 being unable to enter the drum 207, affecting the fixed installation of the crushing hammer 302. When the hydraulic rod 204 pulls the moving rod 205 to move to the left, it will drive the limiting plate 206 to move together, and pull the limiting rod 211 out of the limiting groove 212, without affecting the subsequent rotation of the drum 207.
