Description

Technical Field

[0001] This utility model relates to the field of oscillating pellet mill technology, specifically to an oscillating pellet mill that can be adjusted in both directions. Background Technology

[0002] A gyratory pellet mill uses the alternating forward and reverse oscillation of rollers to pass wet powder through screens of different diameters into pellets of different sizes, which are used as intermediate pellets in the manufacture of granules or tablets.

[0003] The screen shafts of current gyratory pellet mills are mainly used to adjust the tension of the screen so that it can fit against the rollers. Since both ends of the screen are free, two screen shafts are needed to tighten both ends of the screen. However, the two screen shafts of the existing gyratory pellet mills are controlled separately, requiring adjustment of one end first and then the other end. It is not possible to tighten both sides of the screen at the same time. Therefore, this application proposes a gyratory pellet mill that can be adjusted in both directions. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing a bidirectional adjustable oscillating pellet mill, thereby resolving the problems described above.

[0005] This utility model provides a bidirectional adjustable oscillating pellet mill, including a machine body, an oscillating shell on the machine body, an oscillating wheel inside the oscillating shell, and a reciprocating mechanism inside the machine body for driving the oscillating wheel to reciprocate; a screen shaft inside the oscillating shell for adjusting the screen tension; and a synchronous reversing mechanism for causing the two screen shafts to rotate synchronously in opposite directions. The synchronous reversing mechanism is rotatably disposed inside the machine body, and the ends of the screen shafts are provided with insertion parts. The synchronous reversing mechanism includes insertion shafts for inserting into the insertion parts, so that the screen shafts and the synchronous reversing mechanism can be detachably connected.

[0006] Preferably, the synchronous reversing mechanism further includes a first sprocket, a second sprocket, a first gear, and a second gear. The first sprocket is coaxially connected to one of its insertion shafts, the first gear is coaxially connected to another insertion shaft, the second sprocket is coaxially connected to the second gear via a rotating shaft, the first gear and the second gear mesh and drive each other, and the first sprocket is connected to the second sprocket via a transmission chain to realize the transmission between the transmission sprockets, thereby enabling the gears to rotate synchronously.

[0007] Preferably, the insertion part is a cross-shaped insertion structure, and the insertion shaft is provided with a cross-shaped insertion groove for insertion into the insertion part. The insertion shaft and the rotating shaft are rotatably mounted in the machine body via bearings, so that the synchronous reversing mechanism rotates stably within the machine body.

[0008] Preferably, a ratchet is provided at one end of the screen shaft, and a pawl for one-way locking with the ratchet is provided on one side of the swing housing. A feed hopper is provided on the upper side of the swing housing, and a discharge hopper is provided on the lower side of the swing housing. Cover plates are detachably provided on both sides of the swing housing by bolts, and the screen is removed by opening the cover plates.

[0009] Compared with existing technologies, it has the following beneficial effects:

[0010] This application incorporates a synchronous reversing mechanism within the machine body. The insertion part at the end of the screen shaft connects to the insertion shaft on the synchronous reversing mechanism, allowing the two screen shafts to rotate synchronously in opposite directions. This synchronously tightens the screens inserted into the holes at both ends of the screen shafts. Rotating either screen shaft drives the other screen shaft to rotate synchronously in opposite directions, adjusting the screen tension. This effectively improves the screen adjustment efficiency while also facilitating screen disassembly and installation. Attached Figure Description

When either screen shaft 5 is rotated, the insertion shaft 61 connected to the screen shaft 5 rotates, thereby causing the two insertion shafts 61 to rotate synchronously in opposite directions through the first sprocket 62, the second sprocket 63, the first gear 64, and the second gear 65, so as to realize the synchronous reversing rotation of the two screen shafts 5, so as to adjust and tighten the screen 4 at both ends.

[0028] See Figure 3 In this application, a ratchet 52 is provided at one end of the screen shaft 5, and a pawl 7 is provided on one side of the rocker housing 2 for unidirectional locking with the ratchet 52, so that the ratchet 52 can be unidirectionally locked when the screen shaft 5 is rotated.

[0029] See Figure 2 The upper side of the swaying shell 2 of this application is provided with a feed hopper 21, and the lower side of the swaying shell 2 is provided with a discharge hopper 22, so as to feed material through the feed hopper 21 and discharge material through the discharge hopper 22.

One end of the rotating rod is connected to the transmission shaft on the end of the swaying wheel 3 through a linkage gear, so that when the swaying wheel 3 swings, the rotating rod swings synchronously to pre-crush the large pieces of raw material falling into the feed hopper 21, so that the swaying wheel 3 can crush the crushed raw material in the screen 4, effectively improving the crushing efficiency of large pieces of raw material.

[0030] See Figure 2 The two sides of the swing housing 2 of this application are detachably provided with cover plates 23 by bolts, so as to open the two side openings of the swing housing 2 by providing cover plates 23 for replacing the screen 4.
