Description

Technical Field

[0001] The invention relates to a swing pellet machine. Background Art

[0002] The swing granulator is a specialized device that grinds wet powder or dry bulk materials into the desired granules. It primarily forces the wet powder mixture through a screen under the forward and reverse rotation of a rotating drum, resulting in granules. It consists of a frame with a hopper mounted on top, a drum mounted below the hopper, and a screen attached to the bottom of the drum. The screen is secured at both ends by mesh shafts. The rotation of the drum forces the wet powder through the screen to form granules. It features simple operation and a compact structure.

[0003] The existing swing pellet machine uses a drum lying horizontally below a hopper, with a drum shaft fixed to the drum, which is fixed to a bearing seat. A screen is installed below the drum, wrapping around the drum. A discharge port is located below the hopper. During operation, the motor serves as the power source, and the roller shaft drives the drum to swing back and forth through a connecting rod mechanism and rack transmission. The reciprocating swing angle is less than 360 degrees, thereby squeezing the material through the screen and pelletizing it. However, the drum of this type of swing pellet machine cannot be disassembled, and the screen is very inconvenient to install and replace, which is not conducive to subsequent cleaning and maintenance. Summary of the Invention

[0004] In view of the defects of the above-mentioned prior art, the main purpose of the present invention is to overcome the shortcomings of the prior art and discloses a swinging granulator, including a shell, a hopper, a screen, a roller, a screen adjusting rod and a driving mechanism. A crushing chamber is arranged in the shell, the roller is rotatably arranged in the shell, and is connected to the driving mechanism, and the roller is driven to swing back and forth by the driving mechanism. The screen adjusting rod is arranged on both sides of the roller, the screen is placed under the roller, and the two ends are respectively installed on the screen adjusting rods on both sides. The hopper is fixed on the shell and the discharge port is located above the roller.

[0005] Furthermore, the screen adjustment rod includes a fixed seat, a camshaft, a ratchet and a locking block. The camshaft is rotatably set on the fixed seat, the fixed seat is rotatably set in the shell, and one end extends to the outside of the shell to install the ratchet, and a locking block for locking the ratchet is installed on one side.

[0006] Furthermore, rounded corners are provided around the periphery of the fixing seat.

[0007] Furthermore, steel thorn surfaces are provided on the camshaft and the fixing seat.

[0008] Furthermore, the driving mechanism includes a cam, a motor, a bracket, a driving block and a crankshaft, the crankshaft is arranged on the roller, the driving block is provided with a first driving groove and a second driving groove, the driving block is slidingly arranged on the housing, the crankshaft is placed in the first driving groove, the cam is arranged in the second driving groove, the motor is arranged above the cam through the bracket and is connected to the cam, the motor drives the cam to rotate to drive the driving block to slide back and forth, and then drives the roller to swing through the crankshaft.

[0009] Furthermore, the roller includes an end cover, a rotating shaft and a rolling strip. The end covers are respectively arranged at both ends of the rolling strip, and the rolling strips are arranged at equal intervals in the circumference of the end cover. The rotating shaft is axially extended from the end cover.

[0010] Furthermore, the rolling strip is a square strip structure, and the diagonal line is located at the radial extension of the end cover.

[0011] Furthermore, doors are provided on both sides of the shell.

[0012] The beneficial effects achieved by the present invention are:

[0013] This invention improves the structure of the existing screen adjustment lever by employing a camshaft in conjunction with a fixed seat. The camshaft's variable diameter allows the clamping area to be enlarged or reduced, enabling quick installation and removal of the screen. The drive mechanism uses a cam to control the reciprocating motion of the drive block. The drive slot and crankshaft control the reciprocating swing of the roller, preventing frequent forward and reverse rotation of the motor, which could shorten its service life.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] A swing pellet machine, such as Figure 1-4 As shown, it includes a shell 1, a hopper 2, a screen 3, a roller 4, a screen adjusting rod 5 and a driving mechanism 6. A crushing chamber is set in the shell 1, and the roller 4 is rotatably set in the shell 1 and is connected to the driving mechanism 6. The driving mechanism 6 drives the roller 4 to swing back and forth. The screen adjusting rod 5 is set on both sides of the roller 4, the screen 3 is placed under the roller 4, and the two ends are respectively installed on the screen adjusting rod 5 on both sides. The hopper 2 is fixed on the shell 1 and the discharge port is located above the roller 4.

[0023] In one embodiment, if Figure 1-5 As shown, the screen adjustment rod 5 includes a fixed seat 51, a camshaft 52, a ratchet 53 and a locking block. The camshaft 52 is rotatably set on the fixed seat 51. Through the characteristic of the cam variable diameter, a clamping area is formed between the camshaft 52 and the bottom of the fixed seat 51. After the screen 3 is inserted into the clamping area, the screen can be fixed by pulling it in the reverse direction. The fixed seat 51 is rotatably set in the housing 1, and one end extends to the outside of the housing to install the ratchet 53, and a locking block for locking the ratchet 53 is installed on one side. The reverse locking of the screen adjustment rod 5 is achieved by the ratchet 53 and the locking block. When installing the screen 3, the camshaft 52 is rotated clockwise so that the protruding part of the camshaft 52 is located above the fixed seat 51. At this time, the camshaft 52 and the fixed seat 51 are in a relaxed state. The screen 3 can be easily inserted into the clamping area from the bottom of the clamping area, and the screen 3 can be clamped by pulling it downward. When removing the screen 3, since the camshaft 52 and the fixing seat 51 are in a clamped state, the screen 3 can be quickly clamped by pulling it upward. Manually controlling the camshaft 52 to rotate counterclockwise, the protruding portion of the camshaft 52 naturally faces downward. At this time, there is a large gap between the bottom of the camshaft 52 and the fixing seat 51, which makes it easy to pull out the screen 3. As can be seen, the above operation can quickly and reliably remove the screen 3. In addition, the ratchet 54 and the locking block are used to adjust the tension of the screen 3 by rotating the fixing seats 51 on both sides.

[0024] In one embodiment, if Figure 1-5As shown, in order to reduce the damage of the corners of the fixing seat 51 to the screen, it is well known that applying pressure to the screen at a corner may cause creases on the screen, so rounded corners are set around the fixing seat.

[0025] In one embodiment, if Figure 1-5 As shown, steel thorn surfaces are provided on the camshaft 52 and the fixing seat 51 to increase the clamping force on the screen.

[0026] In one embodiment, if Figure 1-5 As shown, the drive mechanism 6 includes a cam 61, a motor 62, a bracket, a drive block 64, and a crankshaft 65. The crankshaft 65 is mounted on the roller 4 and drives the roller 4 to move. The drive block 64 is provided with a first drive slot 641 and a second drive slot 642. The drive block 64 is slidably mounted on a side panel of the housing 1. The crankshaft 65 is positioned within the first drive slot 641, and the cam 61 is positioned within the second drive slot 642. The motor 62 is mounted above the cam 61 via a bracket and is connected to the cam 61. The motor 62 drives the cam 61 to rotate, thereby driving the drive block 64 to slide back and forth, thereby driving the roller 4 to swing via the crankshaft 65. Two parallel guide rails are provided, and the drive block 64 is mounted on both guide rails to distribute the drive load and increase the service life of the guide rails.

[0027] In one embodiment, if Figure 1-5 As shown, roller 4 includes end caps 41, a rotating shaft 42, and a rolling strip 43. End caps 41 are disposed at both ends of rolling strip 43. Rolling strips 43 are arranged at equal intervals around end caps 41. Rotating shaft 42 is axially extended from end caps 41. Preferably, rolling strip 43 is a square strip structure, with the diagonal line located at the radial extension of end caps 41.

[0028] In one embodiment, if Figure 1-5 As shown, doors are provided on both sides of the housing 1 to facilitate the control of the screen adjustment rod 5.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. If the present invention is modified or replaced with equivalents without departing from the spirit and scope of the present invention, they should be included in the scope of protection of the claims of the present invention.
