Description

Thermoplastic elastomer pelletizer Technical Field

[0001] This utility model relates to the technical field of thermoplastic elastomer pelletizers, specifically thermoplastic elastomer pelletizers. Background Technology

[0002] Thermoplastic elastomers, also known as synthetic rubber or artificial rubber, require pelletizers for processing. Pelletizers are used to cut thermoplastic elastomers into small pellets of equal volume. Currently, there are many types of thermoplastic elastomer pelletizers on the market to meet different needs.

[0003] However, a utility model patent with authorization announcement number CN220052084U discloses a thermoplastic elastomer pelletizer, relating to the field of pelletizer technology. It includes a conveying platform and a longitudinal cutting mechanism and a transverse cutting mechanism sequentially mounted on the platform along its conveying direction. The longitudinal cutting mechanism includes a first frame and a first pressure plate fitted to the bottom of the first frame. A gap is left between the first pressure plate and the conveying platform for conveying thermoplastic elastomer sheets. Several cutting blades are rotatably mounted within the first frame via shafts. This thermoplastic elastomer pelletizer replaces the traditional stamping-type pelletizing structure with a sequentially mounted longitudinal and transverse cutting mechanism. It can first longitudinally cut the thermoplastic elastomer sheets into several strips, and then transversely cut these strips using the transverse cutting mechanism to complete the pelletizing operation. The first and second pressure plates limit the conveyed sheets, ensuring stable cutting and conveying.

[0004] The existing technical solutions described above have the following drawbacks: while thermoplastic elastomers are slit using cutting discs and blades, the spacing is fixed, making it inconvenient to cut particles of different sizes. Furthermore, the slit particles are scattered on the conveying table, making collection troublesome and time-consuming, thus reducing work efficiency. Additionally, dust is generated during the conveying of thermoplastic elastomers, resulting in dust contamination on the slit particles. Therefore, we propose a thermoplastic elastomer pelletizer to solve the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a thermoplastic elastomer pelletizer to solve the problems mentioned in the background art, such as the inconvenience of adjusting the blade spacing to cut different particle sizes, the inconvenience of collecting the cut particles, and the difficulty of cleaning dust from the thermoplastic elastomer plastic.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thermoplastic elastomer pelletizer, comprising: a worktable, a frame fixedly connected to the upper end of the worktable for bearing, and a first cleaning brush bolted to the lower left end of the worktable;

[0007] Also includes:

[0008] The upper end of the frame is bolted to a cylinder, and the lower end of the cylinder is equipped with a connecting frame. The lower side of the connecting frame is provided with an adjustment structure and a collection structure. The adjustment structure includes a first mounting frame, a first threaded rod, a motor, a first limiting ring, a first blade, a second mounting frame, a second threaded rod, a second limiting ring, a mounting plate, and a second blade. The collection structure includes a storage box, a guide tube, a suction head, a sealing plate, a connecting tube, and an air extraction tube.

[0009] The upper end of the first cleaning brush is symmetrically equipped with an electric telescopic rod, and the upper end of the electric telescopic rod is bolted to the lower end of the second cleaning brush.

[0010] Preferably, a first mounting bracket is fixedly connected to the lower left end of the connecting bracket, and a first threaded rod is rotatably connected to the inner end of the first mounting bracket, and a motor is installed at the rear end of the first threaded rod.

[0012] Preferably, a second mounting bracket is fixedly connected to the lower right end of the connecting bracket, and a second threaded rod is fixedly connected to the inner end of the second mounting bracket. At the same time, mounting plates are connected through the second threaded rod at equal intervals.

[0013] Preferably, a second limiting ring is threaded onto the second threaded rod, and the second limiting ring is symmetrically arranged about the longitudinal central axis of the mounting plate, and a second blade is installed at the lower end of the mounting plate.

[0014] Preferably, a storage box is placed at the lower right end of the workbench, and a guide tube is bolted to the upper right end of the storage box. A suction head is embedded in the upper end of the guide tube, and the lower end of the suction head is attached to the upper right end of the workbench.

[0015] Preferably, a sealing plate is internally engaged with the left end of the storage box, and a connecting pipe is bolted to the upper rear end of the storage box, with an air extraction pipe bolted to the rear end of the connecting pipe.

[0016] Preferably, the front end of the connecting tube has a mesh structure, and the suction head is connected to the connecting tube through a guide tube and a storage box.

[0017] Preferably, the size of the second cleaning brush is equal to the size of the first cleaning brush, and the second cleaning brush and the first cleaning brush form a lifting structure.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the thermoplastic elastomer pelletizer is easy to adjust the blade spacing to cut different particle sizes, and it is also convenient to collect the cut particles and easy to clean the dust on the thermoplastic elastomer plastic.

[0019] 1. It is provided with a first threaded rod and a second threaded rod. The first threaded rod is connected with first blades at equal intervals, so that the first blades can move on the first threaded rod to adjust the spacing. The inner end of the first limiting ring, which is symmetrically arranged at the front and rear, tightly abuts against the first blades to limit their movement.

[0020] The second threaded rod is connected to mounting plates at equal intervals, allowing the first blade to move on the second threaded rod to adjust the spacing.

[0021] 2. It is equipped with a suction head and a collection box. The suction head is connected to the connecting pipe through the guide pipe and the collection box, so that the particles on the upper part of the worktable can enter the inside of the collection box through the suction head and the guide pipe, thus facilitating the collection of the cut particles.

[0022] 3. The structure is designed with a first cleaning brush and a second cleaning brush, and the second cleaning brush and the first cleaning brush together enable the electric telescopic rods arranged symmetrically to drive the second cleaning brush to descend.

[0023] Place the inner ends of the first and second cleaning brushes against the upper and lower ends of the thermoplastic elastomer plastic, respectively, to easily clean the dust off the thermoplastic elastomer plastic. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please refer to Figures 1-6. The present invention provides a technical solution: a thermoplastic elastomer pelletizer, including a workbench 1, a frame 2, a cylinder 3, a connecting frame 4, a first mounting frame 5, a first threaded rod 6, a motor 7, a first limiting ring 8, a first blade 9, a second mounting frame 10, a second threaded rod 11, a second limiting ring 12, a mounting plate 13, a second blade 14, a storage box 15, a guide pipe 16, a suction head 17, a sealing plate 18, a connecting pipe 19, an air extraction pipe 20, a first cleaning brush 21, an electric telescopic rod 22, and a second cleaning brush 23.

[0033] Example 1: Existing methods for slitting thermoplastic elastomers using cutting blades and cutters have fixed spacing, making it inconvenient to cut particles of different sizes. Therefore, this example addresses this issue with the following technical solution, as shown in Figures 1, 2, and 4. The adjustment structure includes a first mounting bracket 5, a first threaded rod 6, a motor 7, a first limiting ring 8, a first blade 9, a second mounting bracket 10, a second threaded rod 11, a second limiting ring 12, a mounting plate 13, and a second blade 14. The first threaded rod 6 has the first blades 9 connected at equal intervals. The first limiting rings 8 are symmetrically arranged about the longitudinal axis of the first blades 9. The second threaded rod 11 has the mounting plate 13 connected at equal intervals. The second limiting rings 12 are symmetrically arranged about the longitudinal axis of the mounting plate 13. Therefore, the dimensions of the first blades 9 and 14 are adjusted according to the desired particle size. The equally spaced first blades 9 are pushed to move on the first threaded rod 6. After the position is adjusted, the first limiting rings 8 at both ends of the first blade 9 are rotated, allowing the first limiting rings 8 on the first threaded rod 6 to move. The cylinder moves upward until the inner end of the first limiting ring 8, which is symmetrically arranged front and back, tightly abuts against the front and back walls of the first blade 9, thus limiting the position of the first blade 9 on the first threaded rod 6. The mounting plate 13, which is equidistantly arranged, is pushed to move on the second threaded rod 11. After the position is adjusted, the second limiting rings 12 at the front and back ends of the mounting plate 13 are rotated respectively, so that the second limiting rings 12 move on the worktable 1 until the inner end of the second limiting rings 12, which is symmetrically arranged front and back, tightly abuts against the front and back walls of the mounting plate 13, thus limiting the position of the mounting plate 13 on the second threaded rod 11. When the cylinder 3 works, it drives the connecting frame 4 to descend, so that the lower ends of the first blade 9 and the second blade 14 abut against the thermoplastic elastomer plastic placed on the upper end of the worktable 1. When the motor 7 works, it drives the first threaded rod 6 to rotate on the first mounting frame 5, so that the first blade 9 performs transverse cutting on the thermoplastic elastomer plastic, while the equidistant second blade 14 performs longitudinal cutting on the thermoplastic elastomer plastic, thereby facilitating the adjustment of the spacing between the first blade 9 and the second blade 14 to cut different particle sizes.

[0034] Example 2: Existing thermoplastic elastomer plastics generate dust during transport, resulting in dust contamination on the cut granules. Therefore, this example uses the following technical solution, as shown in Figures 1 and 3. Since the upper end of the first cleaning brush 21 is symmetrically equipped with an electric telescopic rod 22, and the size of the second cleaning brush 23 is equal to that of the first cleaning brush 21, the second cleaning brush 23 and the first cleaning brush 21 form a lifting structure. Therefore, during cutting, the lower end of the thermoplastic elastomer plastic adheres to the upper end of the first cleaning brush 21. When the symmetrically arranged electric telescopic rod 22 operates, it drives the second cleaning brush 23 to descend until the lower end of the second cleaning brush 23 adheres to the upper end of the thermoplastic elastomer plastic. As the thermoplastic elastomer plastic moves, the first cleaning brush 21 and the second cleaning brush 23 clean the thermoplastic elastomer plastic, thus easily removing dust from the thermoplastic elastomer plastic.

[0035] Example 3: Currently, the cut particles are scattered on the conveying table, making collection cumbersome and time-consuming, reducing work efficiency. Therefore, this example uses the following technical solution, as shown in Figures 1, 5, and 6. The collection structure includes a collection box 15, a guide pipe 16, a suction head 17, a sealing plate 18, a connecting pipe 19, and an air extraction pipe 20. The lower end of the suction head 17 is attached to the upper right end of the worktable 1. The front end of the connecting pipe 19 has a mesh structure. The suction head 17 is connected to the connecting pipe 19 through the guide pipe 16 and the collection box 15. Therefore, after the thermoplastic elastomer plastic granules are cut, the sealing plate 18 is snapped into the left end of the storage box 15. When the suction pipe 20 is working, the gas inside the suction head 17 and the storage box 15 is extracted through the connecting pipe 19, allowing the granules on the upper end of the workbench 1 to enter the interior of the storage box 15 through the suction head 17 and the guide pipe 16. The mesh structure at the front end of the connecting pipe 19 evenly prevents the granules from entering the suction pipe 20, thus facilitating the collection of the cut granules. All the electrical components mentioned above are existing technologies and will not be described in detail here.

[0036] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
