The above patent has a crushing shaft, a crushing plate and a driving part, so that during packaging, it is necessary to continuously add material to the discharge trough. At this time, the double-headed motor is started, and the two synchronous heads and synchronous belts on the top of the motor make the rotating rods on the two side horizontal plates rotate continuously, so that the main bevel gear drives the auxiliary bevel gear to rotate continuously, and then the crushing shaft inside the discharge trough drives the crushing plate to rotate, and the added powder is crushed, so that the discharge end is not easy to be blocked, and the discharge amount is stable, avoiding the problem of quantitative guarantee due to the presence of lumps in each discharge. However, in actual use, there are still the following shortcomings: the distance between the output end of the packaging machine and the packaging bag is relatively fixed. When it is necessary to feed packaging bags of different capacities, it is not easy for the packaging machine to adjust the height of the discharge end, and it is not easy for the packaging machine to fix packaging bags of different capacities, and the applicability of the packaging machine is low.

[0004] Therefore, a packaging machine that can be raised and lowered is needed to solve the problems in the prior art that the height of the discharge end of the packaging machine is not easy to adjust according to the capacity of the packaging bag, and it is not easy to fix packaging bags of different capacities.

[0023] The lifting mechanism 4 includes a forward and reverse motor 41 and two parallel guide columns 44. The forward and reverse motor 41 is fixedly connected to the center of the top surface of the transverse section of the U-shaped frame 3. The output end of the forward and reverse motor 41 rotates through the bottom surface of the transverse section of the U-shaped frame 3 and is coaxially fixedly connected with a threaded rod 42. The bottom end of the threaded rod 42 is rotatably connected to the top surface of the support block 2. The outer surface of the threaded rod 42 is threadedly connected with a threaded sleeve 43. The outer wall of one end of the threaded sleeve 43 is fixedly connected to the outer wall of one end of the storage box 5. The top ends of the two guide columns 44 are fixedly connected to the bottom surface of the transverse section of the U-shaped frame 3. The bottom ends of the two guide columns 44 slide through the bottom surface of the threaded sleeve 43 and are fixedly connected to the top surface of the support block 2.

[0024] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth explaining in detail that the bag placing assembly 7 includes a bagging barrel 71, the bottom end of the bagging barrel 71 is fixedly connected to the top surface of the workbench 1, and slide grooves 72 are provided on both sides of the outer surface of the bagging barrel 71. The inner wall of the slide groove 72 is slidably connected to a slide rod 73, and the top ends of the two slide rods 73 slide through the top of the bagging barrel 71 and are fixedly connected to the same extension ring 74. The bottom of the outer surface of the slide rod 73 close to the slide groove 72 is fixedly connected to a connecting rod 75, and the outer wall of the connecting rod 75 away from the slide rod 73 passes through the slide groove 72 and is fixedly connected to a fixing plate 76, and the top surfaces of the two fixing plates 76 are fixedly connected to the bottom surface of the storage box 5.

[0025] Further as Figure 1 and Figure 4 As shown, it is worth explaining in detail that the outer walls of the two fixing plates 76 close to the extension ring 74 are fixedly connected to the electric push rod 8, the output end of the electric push rod 8 is fixedly connected to the arc-shaped clamping plate 9, and the inner circle of the arc-shaped clamping plate 9 is fixedly connected to the anti-slip pad 10.

[0026] Further as Figure 1 As shown, it is worth explaining in detail that the top surface of the storage box 5 is fixedly connected to a feeding funnel 11, and a glass plate 12 is embedded in the outer wall of one end of the storage box 5 away from the threaded sleeve 43, so as to facilitate observation of the charging capacity inside the storage box 5.

[0027] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth explaining in detail that the automatic discharge port 6 is coaxially arranged with the bagging barrel 71 to ensure that the material falls into the packaging bag accurately. The bagging barrel 71 and the extension ring 74 have the same inner diameter, which facilitates the placement of the packaging bag into the bagging barrel 71.

[0028] Further as Figure 1 and Figure 4As shown, it is worth explaining in detail that the arc-shaped clamping plate 9 is at the same height and level as the extension ring 74, the inner diameter of the anti-slip pad 10 is the same as the outer diameter of the extension ring 74, and the arc-shaped clamping plate 9 is pushed by the electric push rod 8 to drive the anti-slip pad 10 to clamp and fix the packaging bags placed inside the bagging barrel 71 and the extension ring 74.

[0029] In summary: when it is necessary to adjust the height of the discharge end of the packaging machine to accommodate packaging bags of different capacities, turn on the forward and reverse motor 41 to drive the threaded rod 42 to rotate forward. Under the action of the thread, the threaded rod 42 rotates to cause the threaded sleeve 43 to move upward along the two guide columns 44. While moving, the threaded sleeve 43 drives the storage box 5 and the automatic discharge port 6 to rise synchronously, thereby adjusting the relative distance between the automatic discharge port 6 and the workbench 1. Similarly, turning on the forward and reverse motor 41 to drive the threaded rod 42 to rotate in the opposite direction can realize the lowering of the storage box 5 and the automatic discharge port 6. The operation is simple, and effectively avoids the problem that the packaging machine is not easy to adjust the height of the discharge end according to the capacity of the packaging bag.

[0030] When the height of the discharging end of the packaging machine is adjusted, the storage box 5 rises or falls, and the fixed plate 76 rises or falls synchronously. The fixed plate 76 drives the slide bar 73 to rise or fall synchronously in the slide groove 72 through the connecting rod 75, so that the extension ring 74 fixedly connected to the slide bar 73 rises or falls above the bagging barrel 71. When the extension ring 74 is adjusted to a suitable height with the storage box 5, the bottom of the packaging bag is placed on the bottom surface of the bagging barrel 71 through the extension ring 74, and then the extension ring 74 extending out of the extension ring is raised. The packaging bag in part 74 is fitted with the outer wall of the extension ring 74. At this time, the two electric push rods 8 are started, and the two electric push rods 8 push the two arc-shaped clamping plates 9 and the anti-skid pad 10 which are at the same level as the extension ring 74 to move toward the extension ring 74. When the arc-shaped clamping plate 9 moves to the point where the inner surface of the anti-skid pad 10 conflicts with the outer surface of the extension ring 74, the packaging bag is clamped and fixed. Then, the material is put into the packaging bag through the automatic discharge port 6 to carry out the packaging work, which effectively avoids the problem that the packaging machine is not easy to fix packaging bags of different capacities.

[0031] The forward and reverse motor 41 and the electric push rod 8 can be purchased on the market. The forward and reverse motor 41 and the electric push rod 8 are equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so they are not repeated in the specification.
