Description

Technical Field

[0001] The present application relates to the technical field of extruders, and in particular to a granulator with a drying function. Background Art

[0002] Plastic granulator is a molding machine that can make materials into specific shapes by melting the raw materials for extrusion and cutting. Granulator is the most widely used equipment in plastic processing, with simple structure and easy operation.

[0003] In traditional plastic granulators, before putting plastic raw materials into the hopper, some raw materials need to be cleaned. After cleaning, they must be dried and dehydrated before they can be put into the plastic granulator. Drying must be done with independent equipment, which causes energy waste. In addition, the process of transferring the raw materials to the machine body after drying requires multiple human operations, which is time-consuming and affects the processing efficiency. Utility Model Content

[0004] In order to improve processing efficiency, the present application provides a granulator with a drying function.

[0005] The present application provides a granulator with a drying function, which adopts the following technical solution:

[0006] A granulator with a drying function comprises a machine body, wherein a feed port is provided on the machine body, a feed cylinder is fixed at the feed port, a drying cylinder is rotatably arranged at the feed cylinder, a first blocking portion is rotatably arranged at the end of the drying cylinder away from the feed cylinder, a second blocking portion is rotatably arranged at the end of the drying cylinder close to the feed cylinder, and a heating cylinder for heating the drying cylinder is sleeved on the outside of the drying cylinder.

[0007] By adopting the above technical scheme, during the loading process, the raw materials first enter the drying drum and are dried in the drying drum. The raw materials dried in the drying drum enter the feeding drum when the drying drum rotates, so that the raw materials in the feeding drum are in a dried state. The drying drum can be rotated to allow all the raw materials to enter the machine body, which is convenient for the processing process.

[0008] Optionally, a driving motor is fixed to the side wall of the heating cylinder, a driving gear is fixed to the rotating shaft of the driving motor, and the driving gear is connected to the drying cylinder.

[0009] By adopting the above technical solution, a driving motor is fixed to the side wall of the heating cylinder, a driving gear is fixed to the rotating shaft of the driving motor and the driving gear is connected to the drying cylinder. When the driving motor is started, the driving gear is driven to rotate, and the driving gear drives the drying box to rotate, thereby rotating the raw materials inside the drying box, making the drying of the raw materials more uniform and facilitating the drying process.

[0010] Optionally, there are two second blocking parts, both of which are semicircular and rotatably connected to the end of the drying cylinder. A reset torsion spring is provided at the rotating shaft of the second blocking part, and a pushing rod for pushing the second blocking part is fixed to the end of the feeding cylinder.

[0011] By adopting the above technical solution, the reset torsion spring is used to drive the second blocking part to reset, so that the second blocking part blocks the drying part, reducing the possibility of raw material leakage during the drying process and facilitating the raw material drying process.

[0012] Optionally, a plurality of obliquely arranged dispersion plates are fixed to the inner side wall of the drying cylinder.

[0013] By adopting the above technical solution, the dispersion plate has a dispersing effect on the raw materials. During the drying process, the rotation of the drying drum drives the raw materials to rotate inside the drying drum. During the rotation of the raw materials, they contact and disperse with the dispersion plate, reducing the possibility of raw materials sticking.

[0014] Optionally, a first rotating table is fixed to the side wall of the heating cylinder, and a second rotating table is fixed to the side wall of the feeding cylinder, and the first rotating table is rotatably connected to the second rotating table.

[0015] By adopting the above technical solution, the first rotating table is rotatably connected to the second rotating table, so that the heating cylinder and the feeding cylinder can rotate relatively.

[0016] Optionally, a supporting platform for supporting the first rotating platform is fixed to the side wall of the second rotating platform.

[0017] By adopting the above technical solution, a support platform for supporting the first rotating platform is fixed to the side wall of the second rotating platform, and the support platform supports the first rotating platform, thereby reducing the possibility of the position of the first rotating platform being offset.

[0018] Optionally, a rotating motor for driving the first rotating platform to rotate is fixed on the second rotating platform.

[0019] By adopting the above technical solution, the rotating motor is started to drive the first rotating platform to rotate, thereby driving the drying drum to rotate.

[0020] Optionally, a resistance wire is fixed inside the heating tube.

[0021] By adopting the above technical solution, a resistance wire is fixed inside the heating cylinder, and the heating cylinder can have a heating function by heating the resistance wire, so that the drying cylinder can be heated easily.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. During the feeding process, the raw materials first enter the drying drum and are dried in the drying drum. The raw materials dried in the drying drum enter the feeding drum when the drying drum rotates, so that the raw materials in the feeding drum are in a dry state, which is convenient for the processing process;

[0024] 2. A support platform for supporting the first rotating platform is fixed to the side wall of the second rotating platform. The support platform supports the first rotating platform, thereby reducing the possibility of the first rotating platform being offset. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The present application embodiment discloses a granulator with a drying function. Figure 1 , Figure 2 and Figure 3 The granulator with drying function includes a body 1, which is used to process raw materials. A feed port 2 and a discharge port are provided on the body 1. The feed port 2 is convenient for transferring the raw materials to the inside of the body 1 for processing, and the discharge port is convenient for transferring the processed raw materials to the outside of the body 1; a feed cylinder 3 is fixed at the feed port 2 in an integrated manner, and the feed cylinder 3 is coaxially arranged with the feed port 2. A drying cylinder 4 is rotatably arranged at the feed cylinder 3. During the feeding process, the raw materials are transferred to the drying cylinder 4, the raw materials are dried in the drying cylinder 4, and then transferred from the drying cylinder 4 to the feeding cylinder, which is convenient for the raw material processing process; at the same time, a heating cylinder 7 is provided on the outside of the drying cylinder 4, and a resistance wire 16 is fixed in the heating cylinder 7 in an embedded manner. By energizing the resistance wire 16, the heating cylinder 7 has a heating function, which is convenient for heating the drying cylinder 4, thereby drying the raw materials and facilitating the raw material processing process.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The side wall of the heating cylinder 7 is fixed with a driving motor 8 by bolts, and a driving gear 9 is keyed at the rotating shaft of the driving motor 8. A driven tooth is provided on the side wall of the drying cylinder 4, and the driving gear 9 meshes with the driven tooth, thereby connecting with the drying cylinder 4. The driving motor 8 is started to drive the driving gear 9 to rotate, and the driving gear 9 drives the drying cylinder 4 to rotate. At the same time, a plurality of dispersion plates 11 are fixed inside the drying cylinder 4 by an integrated molding method, and the dispersion plates 11 are inclined. The dispersion plates 11 make the raw materials in the drying cylinder 4 fully dispersed during the rotation of the drying cylinder 4, thereby improving the drying efficiency of the raw materials.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The end of the drying cylinder 4 away from the feeding cylinder 3 is rotatably connected with a first blocking portion 5 through a rotating shaft. The first blocking portion 5 is used to close the end of the drying cylinder 4 away from the feeding cylinder 3. The first blocking portion 5 is circular, and the first blocking plate is fixed to the drying cylinder 4 by a snap-fit ​​fixation method; the end of the drying cylinder 4 close to the feeding cylinder 3 is rotatably connected with a second blocking portion 6 through a rotating shaft. There are two second blocking portions 6, and the second blocking portions 6 are both semicircular. When the two second blocking portions 6 abut against each other, the drying cylinder 4 is closed. A reset torsion spring is arranged at the rotating shaft of the second blocking portion 6. The reset torsion spring is used to reset the second blocking portion 6 after rotation A limit block for limiting the position of the second sealing part 6 is fixed to the inner wall of the drying cylinder 4; two push rods 10 are fixed to the end of the feeding cylinder 3 in an integrated manner, and the positions of the two push rods 10 correspond to the positions of the second sealing part 6. When the drying cylinder 4 rotates toward the feeding cylinder 3, the push rod 10 abuts against the second sealing part 6 and pushes the second sealing part to rotate, thereby opening the second sealing part 6 to facilitate the raw materials in the drying cylinder 4 to enter the feeding cylinder 3. At the same time, the push rod 10 is "L" shaped, and the diameter of the drying cylinder 4 is smaller than that of the feeding cylinder 3, which reduces the possibility of leakage of the raw materials during the transfer process.

The first rotating table 12 is rotatably connected to the second rotating table 13 through a rotating shaft, so that the drying cylinder 4 can rotate relative to the feeding cylinder 3. A rotating motor 15 is fixed to the second rotating table 13 by bolts. The rotating shaft key of the rotating motor 15 is connected to the rotating shafts of the first rotating table 12 and the second rotating table 13. When the rotating motor 15 is started, it drives the first rotating table 12 to rotate relative to the second rotating table 13, thereby driving the drying cylinder 4 to rotate. The side wall of the second rotating table 13 is fixed with a support table 14 by an integrated molding method. The support table 14 is used to support the first rotating table 12 to facilitate the positioning of the first rotating table 12.
