Description

Technical Field

[0001] This utility model relates to the field of packaging machines, and in particular to a multi-directional adjustable granule packaging machine feed hopper. Background Technology

[0002] In a conical hopper pellet packaging machine, pellet material enters the conical hopper from storage equipment such as a silo through the feed inlet. Under gravity, the material gradually accumulates and flows downward within the hopper. After the feeding system starts, the material is removed from the hopper and conveyed to a weighing mechanism or packaging area. The weighing system measures the weight of the conveyed material, which is then conveyed to the packaging system. The bag-making machine forms bags from roll film, fills the bags with the material, and then seals them. If pre-made bags are used, a pre-made bag distributor delivers the bags to designated locations, fills them with material, and then seals them. After sealing, the packaged product is discharged from the machine through the unloading system and proceeds to the next process, such as boxing or palletizing. Current pellet packaging machines are typically designed to handle various sizes of pellets. When changing the packaging specifications, the height and tilt angle of the conical hopper need to be adjusted to align with the feed nozzle of the packaging bag. However, the conical hopper and the frame are usually connected by bolts and flanges, which limits the precision of angle and height adjustments and makes operation cumbersome. Utility Model Content

[0017] Example 1, see appendix Figure 1-2 4. A multi-directional adjustable granule packaging machine hopper, comprising a conical storage hopper 1 mounted on an adjusting device. The adjusting device includes an angle adjusting mechanism and a lifting adjusting mechanism. The angle adjusting mechanism includes an adjusting bracket 31 mounted on the upper end of a support 2. A support plate 32 is hinged to the upper end of the adjusting bracket 31. The support plate is hinged to the upper end of the adjusting bracket via two ear plates. The adjusting bracket 31 is fixedly installed. The support plate 32 can rotate at the upper end of the adjusting bracket 31 to adjust the included angle between the two. The support plate 32 is connected to the conical storage hopper 1 for adjustment. A support rod 33 is connected between the side of the bracket 31 and the conical storage hopper 1. One end of the support rod 33 is hinged to the conical storage hopper 1, allowing the support rod 33 to rotate relative to the conical storage hopper 1. The other end has an elongated hole 34 along its length. A positioning hole is provided in the middle of the side plate of the adjusting bracket 31. A locking screw 35 is installed between the elongated hole 34 and the positioning hole. A washer is provided between the screw head of the locking screw 35 and the support rod 33. The locking screw 35 is threaded into the positioning hole. The elongated hole 34 and the locking screw 35 can slide relative to each other.

[0018] A reinforcing plate is provided between the two side plates of the adjusting bracket 31. The reinforcing plate has a threaded hole in the middle, and an auxiliary bolt 36 is connected in the threaded hole. The inner end of the auxiliary bolt 36 is pressed against the lower surface of the support plate 32. The auxiliary bolt 36 supports the support plate 32 and provides support force for the conical storage hopper 1. The auxiliary bolt 36 also assists the support rod 33 in supporting the conical storage hopper 1, ensuring the stability of the conical storage hopper 1.

[0019] When using the angle adjustment mechanism of this embodiment, the locking screw 35 is turned to loosen its lock on the support rod 33, and then the conical storage hopper 1 is held and rotated up and down. The end of the support rod 33 rotates relative to the conical storage hopper 1, and at the same time the elongated hole 34 of the support rod 33 slides relative to the locking screw 35. The support rod 33 remains connected between the two. After the angle of the conical storage hopper 1 is adjusted to the correct position, the locking screw 35 is turned to tighten and lock the support rod 33. The support rod 33 is fixedly supported between the adjusting support 2 and the conical storage hopper 1. Then, the auxiliary bolt 36 is turned to make its end press against the surface of the support plate 32 to provide auxiliary support force for the conical storage hopper 1 and ensure the assembly stability of the conical storage hopper 1.

[0020] Example 2, see appendix Figure 2-5 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the lifting adjustment mechanism includes a rotating support 41, a lead screw 42 and a nut sleeve 43 provided at the lower part of the support plate 32, a lifting plate 44 fixedly provided at the upper part of the conical storage hopper 1, a nut sleeve 43 provided at the lower part of the lifting plate 44, and a lead screw 42 fitted between the nut sleeve 43 and the rotating support 41. The rotating support 41 provides rotational support for the lead screw 42, and a sliding support mechanism is provided between the lifting plate 44 and the support plate 32. The sliding support mechanism provides sliding support for the lifting plate 44, thereby improving the sliding stability of the conical storage hopper 1.

[0021] The lower end of the support plate 32 is provided with a drive assembly, which includes a driven bevel gear 51 connected to the lower end of the lead screw 42, a transverse shaft 53 rotatably connected between two bearings 52, an active bevel gear 54 meshing with the driven bevel gear 51 at the end of the transverse shaft 53, and a handwheel 55 at one end of the transverse shaft 53.

[0022] When the lifting mechanism of this embodiment is in use, rotating the handwheel 55 drives the horizontal shaft 53 and the active bevel gear 54 to rotate. The active bevel gear 54 drives the driven bevel gear 51 and the lead screw 42 to rotate. The lead screw 42 drives the nut sleeve 43 through the thread to raise or lower the lifting plate 44, thereby realizing the height adjustment of the conical storage hopper 1.

[0023] The sliding support mechanism includes guide plates 45 symmetrically arranged on both sides of the lifting plate 44 and a guide wheel 48 assembly fixedly installed in the middle of the side of the support plate 32. The guide plate 45 has a guide groove 46 in the middle. The pulley assembly includes a U-shaped bracket 47 and two guide wheels 48 connected to both ends of the U-shaped bracket 47. The two guide wheels 48 are respectively matched and fitted into the two guide grooves 46. The U-shaped bracket 47 and the guide wheels 48 are fixed on the support plate 32. The lifting plate 44 is connected to the guide wheel 48 through the guide groove 46 on the guide plate 45, thereby establishing a sliding mechanism between the support plate 32 and the lifting plate 44. During the relative sliding and lifting process, the two can be in a sliding connection state.

[0024] The lower part of the guide plate 45 is provided with a support roller 49, which rolls and presses against the outer side of the support plate 32. During the sliding and lifting process of the lifting plate 44, the support roller 49 rolls along the outer side of the support plate 32 to reduce the pressure on the guide wheel 48 and ensure that there is sufficient sliding support strength between the lifting plate 44 and the support plate 32.
