Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a gyratory pellet mill. Background Technology

[0002] Currently, the gyratory pellet mill is a device that uses the gyratory action of a rotating drum to press solid materials into pellets through a screen. It is widely used in food processing, chemical and other industries. The gyratory pellet mill processes moist powders or lumpy dry materials into the required pellets. It is a specialized device that forces moist powders or lumpy dry materials through a screen under the forward and reverse rotation of the drum to form pellets.

[0003] However, when using existing gyratory pellet mills to force solid materials through a screen to form pellets, the rotating drum usually exerts a strong squeezing effect on the solid materials and a weak cutting effect. Because wet powder has strong adhesion, it is easy to agglomerate into large pieces of powder during the extrusion process, and the volume of dry lumps is also usually large. Therefore, the efficiency of the rotating drum in squeezing solid materials through the screen is not high, and it may even cause the drum to jam and be damaged. Utility Model Content

[0004] The purpose of this invention is to provide a gyratory pellet mill to solve at least one of the aforementioned technical problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides a swing pellet mill, including: a machine box, a pelletizing box, a drive mechanism, a drive shaft, a driven shaft, a drum, a screen, and two screen clamping tubes;

[0006] The granulation box is installed on the wall of the machine casing;

[0007] The drive shaft is rotatably mounted inside the chassis. One end of the drive shaft is mounted on the side wall of the chassis away from the granulation box, and the other end passes through the chassis wall and is arranged inside the granulation box. A first disc is provided at the other end of the drive shaft.

[0008] The driven shaft is rotatably mounted on the side wall of the granulation box away from the machine casing, and a second disc is provided at one end of the driven shaft inside the granulation box;

[0009] The roller is installed between the first disc and the second disc. The roller is composed of several rotating shafts arranged in a ring. One end of the rotating shaft is rotatably mounted on the first disc, and the other end is rotatably mounted on the second disc. The outer side of the rotating shaft is provided with a regular square prism structure for cutting and extruding solid materials in the granulation box.

[0010] Two screen clamps are symmetrically arranged on both sides of the drum. The walls of the screen clamps are provided with long slots along the axial direction. The two ends of the screen are respectively embedded in the long slots of the two screen clamps. The screen is wrapped around the bottom of the drum along the circumference of the drum and is used for granulation of solid materials in the granulation box.

[0011] The granulation box has an internal gear ring on one side near the machine casing. Several rotating shafts are each equipped with a first gear at one end near the first disc. The first gear meshes with the internal gear ring for the rotation of the rotating shaft.

[0012] The drive mechanism is located inside the chassis and is connected to the drive shaft. It is used to drive the drive shaft to reciprocate, thereby driving the roller to reciprocate through the first disc. At the same time, the first gear meshes with the internal gear ring to force several rotating shafts to reciprocate in the opposite direction.

[0013] In use, the drive mechanism drives the drive shaft to reciprocate, the first disc drives the roller to reciprocate, and the first gear meshes with the internal gear ring to force several rotating shafts to reciprocate in the opposite direction. The edges of the square prism structure on the rotating shaft are used to cut the solid material into small pieces, and the roller squeezes the solid material through the screen to form solid material particles of the size of the screen pores.

[0014] This application uses a drive mechanism to drive the drive shaft to reciprocate, thereby driving the drum to reciprocate. At the same time, the first gear meshes with the internal gear ring, forcing several rotating shafts to reciprocate in the opposite direction. The edges of the square prism structure on the rotating shafts that rotate in the opposite direction to the drum can better cut solid materials into small pieces, greatly improving the efficiency of extruding solid materials through the screen and reducing the probability of equipment jamming and damage due to the large volume of solid materials.

[0015] Furthermore, the drive mechanism includes: a motor, a reducer, a rack, and a second gear;

[0016] The motor is located at the bottom of the chassis, and the reducer is located above the motor. The output shaft of the motor and the input shaft of the reducer are connected by a belt drive mechanism. The motor drives the input shaft of the reducer to rotate, which in turn drives the output shaft of the reducer to rotate through the transmission mechanism inside the reducer. This converts the high-speed, low-torque rotation of the motor output shaft into the low-speed, high-torque rotation of the reducer output shaft, matching the preset speed required by the drive shaft. Higher torque can drive several rotating shafts to rotate in the opposite direction while driving the roller to rotate.

[0017] The second gear is mounted on the drive shaft, and the drive shaft is equipped with an obliquely arranged rack sliding groove. The rack is slidably disposed in the rack sliding groove, and the rack meshes with the second gear.

[0018] The output shaft of the reducer is connected to the lower end of the rack via a crank-connecting rod mechanism, which drives the rack to slide back and forth in the rack sliding groove. The rack meshes with the second gear, which forces the drive shaft to rotate back and forth. This, in turn, drives the roller to rotate back and forth through the first disc. At the same time, the first gear meshes with the internal gear ring, which forces several rotating shafts to rotate back and forth in the opposite direction.

[0019] Furthermore, the belt drive mechanism includes: a driving pulley, a driven pulley, and a belt;

[0020] The drive pulley is mounted on the output shaft of the motor;

[0021] The driven pulley is mounted on the input shaft of the reducer;

[0023] Furthermore, a fixing plate is provided at the bottom of the chassis, and the motor is mounted on the fixing plate;

[0024] A rotating shaft is provided on one side of the fixing plate, and one side of the fixing plate is rotatably connected to the bottom of the chassis through the rotating shaft;

[0025] A U-shaped notch is provided on the other side of the fixing plate, and an adjusting bolt is fixed to the bottom of the chassis. The adjusting bolt is obliquely inserted into the U-shaped notch.

[0026] An adjusting nut is threaded onto the adjusting bolt. The adjusting nut is located below the fixing plate and is used to support the fixing plate and adjust the angle between the fixing plate and the bottom surface of the chassis.

[0027] A fixing nut is threaded onto the adjusting bolt. The fixing nut is positioned above the fixing plate and is used to fix the fixing plate onto the adjusting nut.

[0028] When installing the belt, place the belt onto the driven pulley of the reducer input shaft; rotate the fixing nut to the top of the adjusting bolt and then rotate the adjusting nut to the bottom of the adjusting bolt; manually increase the angle between the fixing plate and the bottom of the chassis, move the motor upward to shorten the distance between the motor and the reducer, and place the belt onto the drive pulley of the motor output shaft; press down on the fixing plate to force the belt to tension on the drive pulley and the driven pulley; tighten the fixing nut and the adjusting nut downward and upward respectively, clamping and fixing the fixing plate with the fixing nut and the adjusting nut, thereby placing the tensioned belt onto the drive pulley and the driven pulley.

[0029] Preferably, the transmission mechanism within the reducer can be a gear transmission mechanism, a worm gear transmission mechanism, a gear-worm gear transmission mechanism, or other similar transmission mechanisms.

[0030] Furthermore, the crank-connecting rod mechanism includes: a crank and a connecting rod;

[0031] One end of the crank is connected to the output shaft of the reducer;

[0032] One end of the connecting rod is rotatably connected to the other end of the crank, and the other end of the connecting rod is rotatably connected to the lower end of the rack, for converting the rotation of the reducer output shaft into the reciprocating sliding of the rack in the rack sliding groove through the crank-connecting rod mechanism.

[0033] Furthermore, the first disk is provided with a plurality of first through holes, which are arranged in a ring around the drive shaft as the axis, and one end of the rotating shaft is rotatably disposed in the first through hole of the first disk.

[0034] Furthermore, the second disk is provided with a plurality of second through holes, which are arranged in a ring around the driven shaft as the axis. The driven shaft is coaxial with the drive shaft, and the other end of the rotating shaft is rotatably disposed in the second through hole of the second disk.

[0035] Furthermore, a feed hopper is provided on the top of the granulation box for feeding solid materials into the granulation box from the feed hopper.

[0036] Furthermore, a discharge hopper is provided at the bottom of the granulation box for discharging solid material particles from the granulation box.

[0037] Furthermore, the screen clamp tube is rotatably disposed inside the granulation box, one end of the screen clamp tube penetrates the box wall of the granulation box on the side away from the machine box and is disposed on the outside of the granulation box, and one end of the screen clamp tube is provided with a third gear.

[0038] Two rotation limit rods are symmetrically arranged on the outer side of the granulation box on the side opposite to the machine box, and the two rotation limit rods are arranged between the two screen clamp tubes;

[0039] One end of the rotation limiting rod is rotatably mounted on the granulation box, and the other end is provided with a limiting wedge. The limiting wedge meshes with the third gear and is used to limit the third gear, preventing the third gear from rotating toward the limiting rod and thus fixing the screen clamp tube. When the third gear rotates toward the side away from the limiting rod, the limiting wedge does not have a limiting function.

[0040] When adjusting the screen, both ends of the screen are respectively embedded in the elongated slots of the two screen clamping tubes. By adjusting the two third gears to rotate away from the limiting rods, the two ends of the screen are respectively coiled on the screen clamping tubes, thereby covering the bottom of the roller along the circumference of the roller. The limiting wedges of the two rotating limiting rods limit and fix the two screen clamping tubes, thereby fixing the screen.

[0041] Furthermore, the oscillating pellet mill also includes a control system for controlling the start and stop of the oscillating pellet mill;

[0042] The control system mainly includes an AC contactor, an air switch, and a control panel connected by a circuit. The AC contactor and the air switch are both installed at the bottom of the chassis.

[0043] The AC contactor can frequently control the start and stop of the oscillating pellet mill by connecting and disconnecting the control system circuit;

[0044] The air switch is used to protect the control system circuitry;

[0045] The control panel is located on the side wall of the machine casing and is used by the user to operate the oscillating pellet mill.

[0046] Preferably, the control panel is provided with a start button and a stop button, which are used to control the motor to start or stop, respectively.

[0047] Preferably, the control panel is also provided with a running indicator light, which is used to illuminate and indicate when the oscillating pellet mill is running.

[0048] Preferably, both ends of the drive shaft are rotatably mounted on the side walls of the chassis via bearings.

[0049] Preferably, the driven shaft is rotatably mounted on the side wall of the granulation box away from the machine casing via a bearing.

[0050] Preferably, the edges of the regular square prism structure are rounded to prevent the edges of the regular square prism structure from being too sharp and damaging the screen.

[0051] In use, solid material is fed into the granulation box from the feed hopper, and the start button is pressed to start the motor. The output shaft of the motor rotates, driving the input shaft of the reducer to rotate through the belt drive mechanism. This, in turn, drives the output shaft of the reducer to rotate through the transmission mechanism within the reducer, converting the high-speed, low-torque rotation of the motor output shaft into the low-speed, high-torque rotation of the reducer output shaft. The crank-connecting rod mechanism converts the rotation of the reducer output shaft into the reciprocating sliding of the rack in the rack sliding groove. The rack meshes with the second gear, forcing the drive shaft to rotate reciprocally. The first disc drives the roller to rotate reciprocally, and simultaneously, the first gear meshes with the internal gear ring, forcing several rotating shafts to rotate reciprocally in the opposite direction. The edges of the square prism structure on the rotating shafts cut the solid material into small pieces, while the rollers squeeze the solid material through the screen, thus producing solid material particles of the size of the screen openings. The solid material particles in the granulation box are discharged from the discharge hopper.

[0052] By adopting the above technical solution, this utility model has the following beneficial effects:

[0053] This utility model provides a swing pellet mill, which drives the drive shaft to rotate reciprocally, thereby driving the drum to rotate reciprocally. At the same time, the first gear meshes with the internal gear ring, forcing several rotating shafts to rotate in the opposite direction. The edges of the square prism structure on the rotating shafts that rotate in the opposite direction to the drum can better cut solid materials into small pieces, greatly improving the efficiency of extruding solid materials through the screen and reducing the probability of equipment jamming and damage due to the large volume of solid materials.

[0090] In this embodiment, both ends of the drive shaft 11 are rotatably mounted on the side walls of the housing 1 via bearings. The driven shaft 21 is rotatably mounted on the side wall of the granulation box 2 opposite to the housing 1 via bearings.

[0091] Furthermore, the edges of the regular square prism structure 221 are rounded to prevent the edges of the regular square prism structure 221 from being too sharp and damaging the screen 23.

[0092] In use, solid material is fed into the granulation box 2 through the feed hopper 26, and the start button is pressed to start the motor 12. The output shaft of the motor 12 rotates, which drives the input shaft of the reducer 13 to rotate through the belt drive mechanism. In turn, the input shaft of the reducer 13 is driven to rotate through the transmission mechanism inside the reducer 13, thus converting the high-speed, low-torque rotation of the output shaft of the motor 12 into the low-speed, high-torque rotation of the output shaft of the reducer 13. The rotation of the output shaft of the reducer 13 is then converted into the rotation of the rack 14 within the rack sliding groove 114 through the crank-connecting rod mechanism. The drive shaft 11 is forced to reciprocate through the meshing of the rack 14 and the second gear 113. The first disc 111 drives the roller to reciprocate. At the same time, the first gear 222 meshes with the internal gear ring 25, forcing several rotating shafts 22 to reciprocate in the opposite direction. The edges of the square prism structure 221 on the rotating shaft 22 are used to cut the solid material into small pieces. At the same time, the roller squeezes the solid material through the screen 23, thereby making solid material particles with the size of the pores of the screen 23. The solid material particles in the granulation box 2 are discharged from the discharge hopper 27.

[0093] This invention uses a drive mechanism to drive the drive shaft 11 to reciprocate, thereby driving the drum to reciprocate. At the same time, the first gear 222 meshes with the internal gear ring 25, forcing several rotating shafts 22 to reciprocate in the opposite direction. The edges of the square prism structure 221 on the rotating shafts 22 that rotate in the opposite direction to the drum can better cut solid materials into small pieces, greatly improving the efficiency of extruding solid materials through the screen 23 and reducing the probability of equipment jamming and damage due to the large volume of solid materials.
