Description

Technical Field

[0001] This application relates to the field of elastomeric material pelletizing technology, and more particularly to an adjustable underwater pelletizer for elastomeric materials. Background Technology

[0003] The underwater pelletizer in the aforementioned patent requires replacing the entire underwater pelletizer when different sizes of pellets need to be produced, which increases the operating cost and reduces its practicality.

[0004] Therefore, this application proposes an adjustable underwater pelletizer for elastomer materials. Utility Model Content

[0005] This application proposes an adjustable underwater pelletizer for elastomer materials to solve the problems mentioned in the background art. By setting up a pelletizing mechanism, when different specifications of pellets need to be produced, two electric telescopic rods can be activated. The two electric telescopic rods drive the mounting plates connected to them to move relative to each other or away from each other, which can cause the telescopic frame to expand or contract. When the shape of the telescopic frame changes, the distance between the connecting rods will change, thereby adjusting the spacing between the cutters to accommodate different specifications of pellets. It can cut pellets of different sizes, which not only enhances the practicality of the pelletizer, but also reduces production costs, improves production efficiency, and greatly enhances the practicality of the device.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] An adjustable underwater pelletizer for elastomer materials includes a pelletizing box with a movable groove inside. A pelletizing mechanism is installed inside the pelletizing box, comprising mounting plates, a telescopic frame, connecting rods, a cutter, and an electric telescopic rod. A telescopic frame is positioned between two mounting plates. Multiple connecting rods are installed inside the telescopic frame. A cutter is fixedly connected to the bottom end of each connecting rod, and the top end of each connecting rod extends through the movable groove to the outside of the pelletizing box.

[0008] In a preferred embodiment, two electric telescopic rods are symmetrically fixedly connected to the outside of the pelletizing box, and the telescopic ends of the two electric telescopic rods extend into the inside of the pelletizing box and are fixedly connected to the side of the mounting plate away from the telescopic frame.

[0009] By activating two electric telescopic rods, the connected mounting plates can be moved relative to each other or apart, causing the telescopic frame to expand or contract. When the shape of the telescopic frame changes, the distance between the connecting rods changes, thereby adjusting the spacing between the cutters to accommodate different particle sizes. This allows for the cutting of particles of varying sizes, enhancing the practicality of the pelletizer, reducing production costs, and increasing production efficiency, thus improving the overall usability of the device.

[0010] In a preferred embodiment, an anti-sway mechanism is fixedly connected inside the pelletizing box. The anti-sway mechanism includes a limiting plate, a limiting hole, and a limiting block. Each limiting block is fixedly connected to the top of the connecting rod, and the bottom of each limiting block is in contact with the top of the pelletizing box.

[0011] By setting up an anti-sway mechanism, the limiting block at the top of the connecting rod will move synchronously when the telescopic frame moves, which will stabilize the top of the connecting rod and thus improve the practicality of the device.

[0012] In a preferred embodiment, the limiting plate is fixedly connected inside the pelletizing box and located below the telescopic frame. The limiting plate has a limiting hole inside, and the bottom end of each connecting rod extends to the bottom of the limiting plate through the limiting hole.

[0013] By setting an anti-sway mechanism, when the telescopic frame moves, the lower end of the connecting rod will move synchronously within the limiting hole of the limiting plate to stabilize the cutter. This prevents the telescopic frame from becoming unstable during movement and affecting the cutting effect of the cutter, thereby improving the practicality of the device.

[0014] In a preferred embodiment, the pelletizing box is provided with a loading mechanism, which includes a tray, a disc, a sleeve and a screw, and the disc is rotatably connected inside the tray;

[0015] By rotating the disc inside the tray, the elastomer material on the tray can be rotated ninety degrees under the action of the rotating mechanism, changing the direction of the elastomer material and thus improving the practicality of the device.

[0016] In a preferred embodiment, a sleeve is fixedly connected to the bottom of the tray, and a screw is threadedly connected to the inside of the sleeve, with the bottom end of the screw rotatably connected to the inside of the pelletizing box.

[0017] The continuous rotation of the screw causes the sleeve to move the tray downwards synchronously, causing the elastomer material to separate from the cutter. As a result, the disc elastomer material is cut into granules, completing the pelletizing operation, improving pelletizing efficiency, and thus enhancing the practicality of the device.

[0018] In a preferred embodiment, a lifting mechanism is provided on the outside of the screw. The lifting mechanism includes a fixed bracket, a first motor, a worm gear and a worm wheel. The first motor is fixedly connected to the top of the fixed bracket. The worm gear is fixedly connected to the output end of the first motor, and one end of the worm gear is rotatably connected to the inside of the pelletizing box. The worm wheel is fixedly connected to the outside of the screw, and the worm wheel and the worm gear are meshed together.

[0019] The first motor drives the worm to rotate, and the worm meshes with the worm wheel to make the worm wheel rotate. The worm wheel then drives the screw connected to it to rotate. When the screw rotates, it will cause the sleeve to move upward, thereby improving the practicality of the device.

[0020] In a preferred embodiment, the tray is provided with a rotating mechanism, which includes a rotating rod, a second motor, a quarter gear, and a driven gear. The rotating rod is rotatably connected inside the tray, and the top end of the rotating rod is fixedly connected to the bottom of the disc. The output end of the second motor is fixedly connected to the quarter gear, and the driven gear is fixedly connected to the outside of the rotating rod. The driven gear and the quarter gear are meshed together.

[0021] By starting the second motor, the quarter-gear is driven to rotate. The quarter-gear meshes with the driven gear, causing the driven gear to rotate 90 degrees. The rotating rod connected to it will drive the tray to rotate 90 degrees synchronously. At this time, the elastic material on the disc will rotate to another direction, thereby improving the practicality of the device.

[0022] The beneficial effects of this application are:

[0023] 1. This adjustable underwater pelletizer for elastomer materials, by setting up a pelletizing mechanism, can activate two electric telescopic rods when it is necessary to produce pellets of different specifications. The two electric telescopic rods drive the mounting plates connected to them to move relative to each other or away from each other, which can cause the telescopic frame to expand or contract. When the shape of the telescopic movement changes, the distance between the connecting rods will change, thereby adjusting the spacing between the cutters to accommodate pellets of different specifications. It can cut pellets of different sizes, which not only enhances the practicality of the pelletizer, but also reduces production costs, improves production efficiency, and greatly enhances the practicality of the device.

[0024] 2. This adjustable underwater pelletizer for elastomer materials incorporates an anti-sway mechanism. When the telescopic frame moves, the limiting block at the top of the connecting rod moves synchronously, stabilizing the top of the connecting rod. Meanwhile, the lower end of the connecting rod moves synchronously within the limiting hole of the limiting plate, stabilizing the cutter. This prevents instability of the telescopic frame during movement from affecting the cutting effect of the cutter, greatly improving the practicality of the device. Attached Figure Description

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0031] Reference Figure 1-4 An adjustable underwater pelletizer for elastomer materials includes a pelletizing box 1, with a movable groove 11 inside the pelletizing box 1. A pelletizing mechanism 2 is installed inside the pelletizing box 1. The pelletizing mechanism 2 includes a mounting plate 21, a telescopic frame 22, connecting rods 23, a cutter 231, and an electric telescopic rod 24. The telescopic frame 22 is arranged between two mounting plates 21. Multiple connecting rods 23 are arranged inside the telescopic frame 22. The bottom end of each connecting rod 23 is fixedly connected to a cutter 231, and the top end of each connecting rod 23 extends to the outside of the pelletizing box 1 through the movable groove 11.

[0032] Reference Figure 1-4Two electric telescopic rods 24 are symmetrically fixedly connected to the outside of the pelletizing box 1, and the telescopic ends of the two electric telescopic rods 24 extend into the inside of the pelletizing box 1 and are fixedly connected to the side of the mounting plate 21 away from the telescopic frame 22. By activating the two electric telescopic rods 24, the mounting plate 21 connected to them moves relative to each other or away from each other, which causes the telescopic frame 22 to expand or contract. When the shape of the telescopic frame 22 changes, the distance between the connecting rods 23 will change. Thus, the spacing between the cutters 231 can be adjusted to accommodate different specifications of particles and cut particles of different sizes. This not only enhances the practicality of the pelletizer, but also reduces production costs and improves production efficiency, thereby improving the practicality of the device.

[0033] Reference Figure 1-4 An anti-sway mechanism 3 is fixedly connected inside the pelletizing box 1. The anti-sway mechanism 3 includes a limiting plate 31, a limiting hole 32, and a limiting block 33. Each limiting block 33 is fixedly connected to the top of the connecting rod 23, and the bottom of each limiting block 33 is in contact with the top of the pelletizing box 1. By setting the anti-sway mechanism 3, when the telescopic frame 22 moves, the limiting block 33 at the top of the connecting rod 23 will move synchronously, which will stabilize the top of the connecting rod 23, thereby improving the practicality of the device.

[0034] Reference Figure 1-4 The limiting plate 31 is fixedly connected inside the pelletizing box 1 and located below the telescopic frame 22. The limiting plate 31 has a limiting hole 32 inside, and the bottom end of each connecting rod 23 extends to the bottom of the limiting plate 31 through the limiting hole 32. By setting the anti-sway mechanism 3, when the telescopic frame 22 moves, the lower end of the connecting rod 23 will move synchronously in the limiting hole 32 of the limiting plate 31 to stabilize the cutter 231. This prevents the telescopic frame 22 from being unstable during the movement and affecting the cutting effect of the cutter 231, thereby improving the practicality of the device.

[0035] Reference Figure 1-4 The pelletizing box 1 is equipped with a loading mechanism 4, which includes a tray 41, a disc 42, a sleeve 43 and a screw 44. The disc 42 is rotatably connected inside the tray 41. By rotating the disc 42 inside the tray 41, the elastic material on the tray 41 can be rotated to ninety degrees under the action of the rotating mechanism 6, thereby changing the direction of the elastic material and improving the practicality of the device.

[0036] Reference Figure 1-4A sleeve 43 is fixedly connected to the bottom of the tray 41. A screw 44 is threaded inside the sleeve 43, and the bottom end of the screw 44 is rotatably connected to the inside of the pelletizing box 1. With the continuous rotation of the screw 44, the sleeve 43 causes the tray 41 to move down synchronously, so that the elastomer material is separated from the cutter 231. As a result, the elastomer material on the disc 42 will be cut into granules, completing the pelletizing operation, improving pelletizing efficiency, and thus improving the practicality of the device.

[0037] Reference Figure 2 , 4 The screw 44 is externally equipped with a lifting mechanism 5, which includes a fixed bracket 51, a first motor 52, a worm 53, and a worm wheel 54. The first motor 52 is fixedly connected to the top of the fixed bracket 51, and the worm 53 is fixedly connected to the output end of the first motor 52. One end of the worm 53 is rotatably connected to the inside of the pelletizing box 1. The worm wheel 54 is fixedly connected to the outside of the screw 44, and the worm wheel 54 is meshed with the worm 53. The first motor 52 drives the worm 53 to rotate, and the meshing of the worm 53 with the worm wheel 54 causes the worm wheel 54 to rotate. The worm wheel 54 then drives the screw 44 connected to it to rotate. When the screw 44 rotates, it causes the sleeve 43 to move upward, thereby improving the practicality of the device.

[0038] Reference Figure 2 , 4 The tray 41 is equipped with a rotating mechanism 6, which includes a rotating rod 61, a second motor 62, a quarter-gear 63, and a driven gear 64. The rotating rod 61 is rotatably connected inside the tray 41, and its top end is fixedly connected to the bottom of the disc 42. The output end of the second motor 62 is fixedly connected to the quarter-gear 63, and the driven gear 64 is fixedly connected to the outside of the rotating rod 61. The driven gear 64 and the quarter-gear 63 are meshed together. By starting the second motor 62, the quarter-gear 63 is driven to rotate. The quarter-gear 63 meshes with the driven gear 64, causing the driven gear 64 to rotate 90 degrees. Through the rotating rod 61 connected to it, the tray 41 will rotate 90 degrees synchronously. At this time, the elastic material on the disc 42 will rotate to another direction, thereby improving the practicality of the device.

[0039] Working principle: When the elastomer material enters the pelletizing box 1 from the feed inlet and is placed on the disc 42 in the tray 41, the first motor 52 is started to drive the worm 53 to rotate. The worm 53 meshes with the worm wheel 54, causing the worm wheel 54 to rotate. The worm wheel 54 then drives the screw 44 connected to it to rotate. When the screw 44 rotates, it causes the sleeve 43 to move upward. At this time, the tray 41 will move upward in sync, causing the elastomer material on the disc 42 to move closer to the cutter 231. As the elastomer material continues to move upward, it will be cut by the cutter 231 of the connecting rod 23. The cut elastomer material will then be cut by the sleeve 43 and the tray 41 in sync under the continuous rotation of the screw 44, causing the elastomer material to disengage from the cutter 231. Then, the second motor 62 is started to drive the quarter gear 63 to rotate. The quarter gear 63 meshes with the driven gear 64, causing the driven gear 64 to rotate 90 degrees. The connecting rod 61 will drive the tray 41 to rotate 90 degrees synchronously. At this time, the elastic material on the disc 42 will rotate to another direction. After the direction of the elastic material changes, the first motor 52 will drive the worm 53 to rotate. The worm 53 meshes with the worm wheel 54 to make the worm wheel 54 rotate. The worm wheel 54 will then drive the connected screw 44 to rotate. When the screw 44 rotates, it will cause the sleeve 43 to move upward. At this time, the tray 41 will move upward synchronously, making the elastic material on the disc 42 move closer to the cutter 231. When the elastic material continues to move upward, it will be cut by the cutter 231 of the connecting rod 23. After the elastic material is cut, the sleeve 43 will drive the tray 41 to move downward synchronously under the continuous rotation of the screw 44, so that the elastic material is separated from the cutter 231. Thus, the elastic material on the disc 42 will be cut into granules, completing the pelletizing operation and improving pelletizing efficiency.

[0040] When different sizes of pellets need to be produced, the two electric telescopic rods 24 can be activated. The two electric telescopic rods 24 drive the mounting plate 21 connected to them to move relative to each other or away from each other, which can cause the telescopic frame 22 to expand or contract. When the shape of the telescopic frame 22 changes, the distance between the connecting rods 23 will change. Thus, the spacing between the cutters 231 can be adjusted to accommodate different sizes of pellets, and different sizes of pellets can be cut. This not only enhances the practicality of the pelletizer, but also reduces production costs and improves production efficiency.

[0041] By setting the anti-sway mechanism 3, when the telescopic frame 22 moves, the limiting block 33 at the top of the connecting rod 23 will move synchronously, which will stabilize the top of the connecting rod 23. Meanwhile, the lower end of the connecting rod 23 will move synchronously within the limiting hole 32 of the limiting plate 31 to stabilize the cutter 231. This prevents the telescopic frame 22 from becoming unstable during movement and affecting the cutting effect of the cutter 231.

[0042] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and the inventive concept of this application, should be included within the scope of protection of this application.
