Description

Technical Field

[0001] The utility model relates to the technical field of pellet machines, in particular to a large pellet machine for feed production. Background Art

[0002] After the crushed feed raw materials enter the pellet machine, they will encounter a pressing area. In this area, the material will be pressed into high-density pellets. This is achieved by the pressing rollers and molds in the feed pellet machine. The pressing rollers squeeze the raw materials into the small holes of the mold during high-speed rotation. This extrusion will fill the loose gaps in the material to form solid pellets. After the pellets are formed, they will be discharged through the discharge port.

[0003] Due to production design reasons, conventional pellet machines can only be replaced with pellet machines of different specifications when producing pellets of different lengths, which results in high production costs. In addition, conventional pellet machines often experience overheating due to extrusion near the pressure rollers. Therefore, a new type of pellet machine is urgently needed to improve the above problems. Utility Model Content

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Usually, the components of the embodiments of the present utility model described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0035] Accordingly, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0036] As Figures 1 to 7 shown, the present invention includes a reduction gearbox 10 connected to a motor 11. The reduction gearbox inside the box also contains conventional reduction gear oil, etc. It further includes a feeding cylinder 1 for adding feed. A partition bar 101 is installed at the top of the feeding cylinder 1, and a cross-shaped grille 102 is provided at the center of the partition bar 101 to prevent uneven distribution of feed on the pressure plate 6 during feeding.

[0037] A pressure cylinder 2 is fixed below the feeding cylinder 1. Two pressure rollers 4 with opposite directions are arranged inside the pressure cylinder 2 for pressing particles. A transmission shaft 401 is provided at the center of the pressure roller 4. One end of the inner side of the transmission shaft 401 is fixed with a bevel gear a 402 meshing with a bevel gear b 501, and the other end passes through the cylinder wall of the pressure cylinder 2 and is fixed on an outer bearing seat 404.

[0038] A pressure plate 6 fixed on a driving shaft 5 is also arranged inside the pressure cylinder 2. The upper end surface of the pressure plate 6 is tangent to the two pressure rollers 4, and a number of through holes are arranged in a row on the pressure plate 6. The bevel gear b 501 is fixed at the top end of the driving shaft 5. The driving shaft 5 drives the bevel gear b 501 to rotate, and then indirectly drives the two bevel gears a 402 to rotate in opposite directions to cut and press the feed on the pressure plate 6.

[0039] A discharging cylinder 3 is arranged below the pressure cylinder 2. The driving shaft 5 passes through the discharging cylinder 3 downward from the pressure cylinder 2 and is connected to the reduction gearbox 10. A cutting disc 7 is arranged inside the discharging cylinder 3 at a position below the pressure plate 6. The outside of the cutting disc 7 is a ring for fixing, and the ring is fixed on three longitudinal support rods 903 inside the pressure cylinder 2. A guiding disc 8 inclined and fixed on the inner wall of the discharging cylinder 3 is arranged below the cutting disc 7. The guiding disc 8 guides the long strip-shaped finished feed to the discharging port 302. Square holes are arranged on the guiding disc 8 to allow the support rods 903 to pass through to prevent interference.

[0040] The grille 102 extends downward to the bottom of the feeding cylinder 1. A number of vibration motors 103 capable of providing vibration in the up and down direction are arranged on the outer wall of the feeding cylinder 1 to prevent blockage of feeds in different forms during feeding. A protective cylinder 405 that wraps the bevel gear b 501 and the bevel gear a 402 is fixed at the bottom of the grille 102 to prevent entry into the gear transmission during feeding. The optional model of the vibration motor 103 is YZS-1.5-2.

[0041] A support ring a201 is fixed between the blank holder 2 and the blanking cylinder 3. The fixing method can be welding. A number of rubber pads 105 for shock absorption are fixed above the support ring a201 to reduce the overall vibration. The partition 101 is connected to the rubber pads 105 through a number of support columns a104 at the outer bottom; the support ring a201 is supported by a number of support columns b301 fixed to the reduction gearbox 10 below.

[0042] As Figure 3 、 Figure 7 shown, the bearing seat 404 is fixed on the support ring a201. A number of pressing ports 406 are arranged on each pressing roller 4. The port of each pressing port 406 is a parallel inclined chamfer, and the chamfer direction of the lower pressing port 406 is consistent with the rotation direction of the pressure plate 6. The chamfer setting is beneficial to shearing materials with irregular shapes and pressing them into shape; an arc cover 403 for preventing material extrusion is fixed on the rear end face of the pressing roller 4 to avoid incorrect material positions. For example, if conventional materials fall to the position of the arc cover 403, it may cause the pressing roller 4 to not rotate, indirectly causing the motor to overheat.

[0043] The cutting disc 7 consists of a number of cutting edges 701. The cutting edges 701 are connected to the outer ring of the support. The cutting edges 701 are sharp edges in the transverse direction. When the pressure plate 6 rotates, the long strip-shaped finished feed that extends out will also rotate and be contacted by the cutting edges 701 to be cut off. The bottom of each longitudinal support rod 903 is fixedly connected to the transverse support rod 901. The transverse support rod 901 passes through the blanking cylinder 3 and is connected to the piston rod of the lifting electric cylinder 9 outside. A distance sensor 904 is arranged inside the lifting electric cylinder 9 opposite the bottom of the transverse support rod 901 to detect the lifting height of the cutting disc 7 by the lifting electric cylinder 9, enabling the cutting of materials with different lengths extending from the pressure plate 6. Long slot openings are arranged at the positions where the transverse support rod 901 passes through the blanking cylinder 3. An arc-shaped leakage prevention plate 902 is also installed on the transverse support rod 901 and closely adheres to the outside of the blanking cylinder 3. The leakage prevention plate 902 completely covers the long slot openings to prevent the finished materials from leaking out of the slot openings.

[0044] The lifting electric cylinders 9 are all installed on the support ring b1001 on the reduction gearbox 10. An outlet 302 is arranged on the side wall of the blanking cylinder 3.

[0045] An electric control box 12 is arranged behind the motor 11, and a control console 13 is fixed above the electric control box 12 to control the parameters of the whole machine.

[0046] The two forks of the cross-shaped grille 102 face the pressing roller 4 below, enabling the materials to be quickly pressed when descending.

[0047] The mechanical components such as the ferrule and bearing for fixing the components on the shaft in this device, as well as the conventional electrical control components such as the PLC controller and encoder built in the electric control box 12, are well known to those skilled in the art and will not be elaborated herein.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Any other modifications or equivalent substitutions made by those of ordinary skill in the art to the technical solutions of the present invention shall be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
