Description

Technical Field

[0001] This utility model relates to the field of granulator technology, and more specifically, to an extrusion structure for a TPR material granulator. Background Technology

[0002] TPR material is an environmentally friendly polymer material that combines the elasticity of rubber and the processing properties of thermoplastics. It is modified from SBS or SEBS as the base material and is widely used in daily necessities, toys, shoe materials, medical and other fields. TPR material usually needs to be produced and processed into solid granular finished products using a granulator.

[0003] The extruder head structure of a granulator is usually located at the very front of the granulator. The material is extruded through the discharge port at the front of the extruder head. However, the size of the discharge port on the extruder head of existing granulators is fixed. Therefore, the material can only be extruded from the discharge port of the extruder head with a fixed particle size, making it impossible to produce materials with different particle sizes. Utility Model Content

[0004] This invention provides an extrusion structure for a TPR material granulator, which solves the technical problem that the discharge port size of the extrusion mechanism of the existing granulator is fixed, making it impossible to produce materials of different particle sizes.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] An extrusion structure for a TPR material granulator includes a granulator body and a die head located at the front end of the granulator body. The die head is divided into several component chambers by a partition. Several sets of discharge pipes are distributed inside each component chamber, with both ends of the discharge pipes penetrating the front and rear sides of the die head, respectively. A baffle is provided at the junction of the rear end of the die head and the front end of the granulator body. The baffle has a set of openings corresponding to the size of the component chambers. A rotating shaft is rotatably mounted in the middle of the die head. A bracket is fixedly connected to the front side of the die head. One end of the rotating shaft is connected to the baffle, and the other end of the rotating shaft extends out of the outside of the die head and is rotatably connected to the bracket. A rotation control component for driving the rotating shaft to rotate is provided between the bracket and the rotating shaft. A collar is rotatably connected to the front end of the die head. Several sets of blades are distributed on the collar and conform to the front surface of the die head. A drive component for driving the collar to rotate is provided on the die head.

[0007] Furthermore, the rotation control assembly includes a first motor mounted on the bracket, a worm gear connected to the output shaft of the first motor, and a worm wheel sleeved on the surface of the rotating shaft and meshing with the worm gear.

[0008] Furthermore, a guide line is provided on one side of the bracket, and the end of the rotating shaft extends out of the bracket and is connected to a pointer for pointing to the guide line.

[0009] Furthermore, the drive assembly includes a second motor mounted on one side of the front end of the machine head, a gear connected to one end of the output shaft of the second motor, and a gear ring disposed on one side of the collar and meshing with the gear.

[0010] Furthermore, the machine head is connected to an air inlet pipe and an air outlet pipe, and the several sets of compartments are interconnected.

[0011] Furthermore, the granulator body and the die head are connected by a sealing flange.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the rotating control component can drive the rotating shaft to rotate, which in turn drives the baffle to rotate. During this process, when the opening on the baffle rotates to align with the corresponding compartment, the material can enter the discharge pipe inside that compartment and be extruded to the outside. The discharge pipes in other compartments will not have any material entering them due to the obstruction of the baffle. Since the diameter of the discharge pipes in each compartment is different, by controlling the opening on the baffle to align with different compartments, the material can be extruded from the discharge pipes inside different compartments. This allows for flexible adjustment of the particle size of the extruded material, enabling the production of various materials with different particle sizes as needed. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Therefore, 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 invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-5An extrusion structure for a TPR material granulator includes a granulator body 1 and a die head 2 located at the front end of the granulator body 1. A spiral auger inside the granulator body 1 conveys the TPR material to the front end. The die head 2 is divided into several component chambers 4 by a partition 3. Several sets of discharge pipes 5 are distributed within each component chamber 4, with their ends extending to the front and rear sides of the die head 2, respectively. Material conveyed to the front of the granulator body 1 can flow from the rear end of the die head 2 through the discharge pipes 5 to the front end and be extruded to the outside. The diameters of the discharge pipes 5 within different component chambers 4 are different. A baffle 6 is located at the junction of the rear end of the die head 2 and the front end of the granulator body 1. The baffle 6 has a set of openings 7 corresponding to the size of the component chambers 4. When the openings 7 on the baffle 6 are aligned with one of the component chambers 4 inside the die head 2, the material conveyed to the front of the granulator body 1 will pass through the baffle 6 and enter the discharge pipes 5 inside that component chamber 4, while the others... The discharge pipe 5 in the compartment 4 is blocked by the baffle 6, preventing material from entering. A rotating shaft 8 is rotatably installed in the middle of the head 2. A bracket 9 is also fixedly connected to the front side of the head 2. One end of the rotating shaft 8 is connected to the baffle 6, and the other end of the rotating shaft 8 extends out of the outside of the head 2 and is rotatably connected to the bracket 9. A rotation control component is installed between the bracket 9 and the rotating shaft 8. The rotating control component can drive the rotating shaft 8 to rotate, which in turn drives the baffle 6 to rotate. This allows the through 7 on the baffle 6 to rotate to align with different compartment 4 positions. A collar 10 is also rotatably connected to the front end of the head 2. Several sets of blades 11 are distributed on the collar 10 and are attached to the front surface of the head 2. A drive component is installed on the head 2. The drive component can drive the collar 10 to rotate. During this process, the blades 11 can cut the material extruded from the discharge pipe 5 at the front end of the head 2, so that the extruded material can fall in granular form.

[0023] During operation, the material is conveyed to the front end of the granulator body 1 through the conveying auger inside the granulator body 1. When the material at the front end of the granulator body 1 is pushed into the discharge pipe 5 inside the dividing chamber 4, the die head 2 is connected to the air inlet pipe 12 and the air outlet pipe 13. The end of the air inlet pipe 12 is connected to the air cooler, and the several dividing chambers 4 are interconnected. The air inlet pipe 12 can deliver cold air into the several dividing chambers 4. The cold air can cool the material inside the discharge pipe 5, so that the material can be quickly shaped and extruded after passing through the discharge pipe 5. When the drive component drives the collar 10 to rotate, the blades 11 on the collar 10 will rotate and cut the extruded material, so that the TP extruded from the discharge pipe 5 at the front end of the die head 2 is shaped and extruded. Material R can fall in granular form. The rotating control component can drive the rotating shaft 8 to rotate, which in turn drives the baffle 6 to rotate. During this process, when the opening 7 on the baffle 6 rotates to align with the corresponding cavity 4, the material can enter the discharge pipe 5 inside that cavity 4 and be extruded to the outside. The discharge pipes 5 in other cavities 4 will not have any material entering them due to the obstruction of the baffle 6. Since the diameter of the discharge pipes 5 in each cavity 4 is different, by controlling the opening 7 on the baffle 6 to align with different cavities 4, the material can be extruded from the discharge pipes 5 inside different cavities 4. This allows for flexible adjustment of the particle size of the extruded material, enabling the production of various materials with different particle sizes as needed.

[0024] For further details, please refer to Figure 1-5 The rotation control assembly includes a first motor 14 mounted on a bracket 9, a worm gear 15 connected to the output shaft of the first motor 14, and a worm wheel 16 sleeved on the surface of the rotating shaft 8 and meshing with the worm gear 15. The first motor 14 can drive the worm gear 15 to rotate. During this process, the worm gear 15 can drive the meshing worm wheel 16 to rotate, thereby controlling the rotation of the rotating shaft 8 through the worm wheel 16. In addition, a guide line 17 is provided on one side of the bracket 9, and the end of the rotating shaft 8 extends out of the bracket 9 and is connected to a pointer 18 for pointing to the guide line 17. When the rotating shaft 8 drives the pointer 18 to rotate and point to the corresponding guide line 17, the baffle 6 will be aligned with the corresponding set of chambers 4 under the drive of the rotating shaft 8, so that the material can smoothly enter the discharge pipe 5 in the set of chambers 4, making it convenient for the user to adjust the rotation position of the baffle 6.

[0025] For further details, please refer to Figure 1-5The drive assembly includes a second motor 19 mounted on one side of the front end of the head 2, a gear 20 connected to one end of the output shaft of the second motor 19, and a gear ring 21 disposed on one side of the collar 10 and meshing with the gear 20. The output shaft of the second motor 19 can drive the gear 20 to rotate. During the rotation of the gear 20, the gear 20 can drive the gear 20 meshing with it to rotate, thereby causing the collar 10 to rotate under the drive of the gear 20. During the rotation, the blade 11 on the collar 10 can cut the material extruded from the discharge pipe 5, so that the material can fall in granular form.

[0026] For further details, please refer to Figure 1-5 The granulator body 1 and the die head 2 are connected by a sealing flange 22, which makes it easy to remove the die head 2 from the granulator body 1 for cleaning and maintenance of the interior of the granulator body 1 and the die head 2.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
