Description

Technical Field

[0001] This application relates to the field of plastic particle manufacturing technology, and more specifically, to a plastic particle screw extrusion granulation apparatus. Background Technology

[0002] Plastic particles, also known as plastic granules, are raw materials used to store, transport, and process plastics in a semi-finished form. Plastic is a polymer material that can be produced from petroleum as a raw material, such as ethylene, propylene, vinyl chloride, and styrene. The molecules of these substances can react with each other under certain conditions to form compounds with very large molecular weights, i.e., polymers.

[0003] Existing plastic particle screw extrusion granulation equipment is mostly fixed as an integral structure between the discharge frame and the cylinder, making it difficult to control the shape of the base plastic and thus failing to meet the user's needs.

[0004] To address the aforementioned problems, this application provides a screw extrusion granulation apparatus for plastic particles. Utility Model Content

[0005] The plastic particle screw extrusion granulation device provided in this application adopts the following technical solution:

[0006] A screw extrusion granulation apparatus for plastic particles includes a cylinder, an auxiliary mechanism provided on the outer side of the cylinder, and the auxiliary mechanism extending into the interior of the cylinder;

[0007] The auxiliary mechanism includes a discharge frame, which is threaded onto the outside of one side of the cylinder. Multiple discharge slots are evenly distributed around the center line of the discharge frame. A rotating rod is embedded inside the discharge frame. A telescopic rod is fixedly connected to the top of the cylinder, and a top plate is fixedly connected to the top of the telescopic rod. A spring is fixedly connected between the cylinder and the top plate, and the spring is sleeved on the outside of the telescopic rod. A positioning rod is fixedly connected to the top of the top plate. A positioning groove is formed on the top of the discharge frame, and the bottom end of the positioning rod extends into the positioning groove. A connecting component is provided on the outside of the positioning rod.

[0008] Furthermore, the rotating rod is movably connected to the discharge frame via a bearing, the positioning rod matches the positioning groove, and a sealing ring is fixedly connected to one side of the cylinder, with the sealing ring embedded between the cylinder and the discharge frame.

[0009] By using the above technical solution, the positioning effect of the discharge frame can be improved because the positioning rod matches the positioning groove, thus preventing the discharge frame from rotating on its own.

[0010] Furthermore, the connecting component includes two handles, which are respectively fixedly connected to the front and rear sides of the discharge frame.

[0011] The above technical solution, by setting two handles, makes it easier for users to rotate the discharge frame later.

[0012] Furthermore, a motor is fixedly connected to the other side of the cylinder, a support plate is fixedly connected to the bottom of the motor, the support plate is fixedly connected to the other side of the cylinder, and a screw conveyor is fixedly connected to the output shaft of the motor.

[0013] The above technical solution, by setting up a support plate, can support the motor, thereby making the motor more stable during use.

[0014] Furthermore, one end of the spiral conveying rod extends into the inside of the cylinder, and the connection between the spiral conveying rod and the cylinder is movably connected by a central bearing. A square groove is provided inside one end of the spiral conveying rod.

[0015] Furthermore, a square block is movably embedded inside the square groove, and one side of the square block is fixedly connected to the rotating rod.

[0016] The above technical solution, by combining square grooves and square blocks, can enhance the support effect on the screw conveyor rod, making the screw conveyor rod more stable and secure when rotating.

[0017] Furthermore, a feed inlet is fixedly connected to the top of the cylinder, and a sealing cap is threaded into the feed inlet. Two bases are fixedly connected to the bottom of the cylinder, and the two bases are symmetrically arranged about the center line of the cylinder.

[0018] The above technical solution, by setting two bases, can support the cylinder.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] In use, the operator can hold the top plate and pull it upwards, causing the positioning rod to move upwards as well. At this time, the telescopic rod's telescopic end is in a stretched state, and the spring is under force and deformed, remaining in a stretched state. Once the positioning rod disengages from the positioning groove, the discharge frame will be in an unrestricted state. Then, the discharge frame can be rotated to remove it and replace it with a discharge frame of a different shape. Through the above structure, the discharge frame can be quickly replaced to adapt to the manufacturing of different plastic particles. Attached Figure Description

[0029] Example:

[0030] This application discloses a screw extrusion granulation apparatus for plastic particles. Please refer to [link to relevant documentation]. Figure 1 and Figure 3 It includes a cylinder 1, an auxiliary mechanism is provided on the outside of the cylinder 1, and the auxiliary mechanism extends into the inside of the cylinder 1;

[0031] The auxiliary mechanism includes a discharge frame 2, which is threaded onto the outside of one side of the cylinder 1. Multiple discharge slots are evenly distributed around the centerline of the discharge frame 2. A rotating rod 3 is embedded inside the discharge frame 2. A telescopic rod 4 is fixedly connected to the top of the cylinder 1, and a top plate 5 is fixedly connected to the top of the telescopic rod 4. A spring 6 is fixedly connected between the cylinder 1 and the top plate 5, and the spring 6 is sleeved on the outside of the telescopic rod 4. A positioning rod 7 is fixedly connected to the top of the top plate 5. A positioning groove is formed on the top of the discharge frame 2, and the bottom end of the positioning rod 7 extends into the positioning groove. The rotating rod 3 and the discharge frame 2 are connected by a bearing. The positioning rod 7 matches the positioning groove. A sealing ring is fixedly connected to one side of the cylinder 1 and is embedded between the cylinder 1 and the discharge frame 2. Because the positioning rod 7 matches the positioning groove, the positioning effect of the discharge frame 2 is improved, preventing the discharge frame 2 from rotating on its own.

[0032] Please see Figure 1 and Figure 2 The positioning rod 7 is provided with a connecting component on its outer side. The connecting component includes two handles 8, which are fixedly connected to the front and rear sides of the discharge frame 2 respectively. A motor 9 is fixedly connected to the other side of the cylinder 1. A support plate 10 is fixedly connected to the bottom of the motor 9. The support plate 10 is fixedly connected to the other side of the cylinder 1. A spiral conveying rod 11 is fixedly connected to the output shaft of the motor 9. By setting two handles 8, it is convenient for the user to rotate the discharge frame 2 later. At the same time, by setting the support plate 10, the motor 9 can be supported, so that the motor 9 can be more stable when in use.

[0033] Please see Figure 2 One end of the spiral conveying rod 11 extends into the inside of the cylinder 1. The connection between the spiral conveying rod 11 and the cylinder 1 is movably connected by a central bearing. A square groove is opened inside one end of the spiral conveying rod 11, and a square block 12 is movably embedded in the square groove. One side of the square block 12 is fixedly connected to the rotating rod 3. The square groove and the square block 12 cooperate to enhance the support effect of the spiral conveying rod 11, making the spiral conveying rod 11 more stable and firm when rotating.

[0034] Please see Figure 1 The top of the cylinder 1 is fixedly connected to a feed inlet 13, and a sealing cap 14 is threaded into the feed inlet 13. The bottom of the cylinder 1 is fixedly connected to two bases 15, which are symmetrically arranged about the center line of the cylinder 1. By setting the two bases 15, the cylinder 1 can be supported.

[0035] The implementation principle of this embodiment is as follows: When in use, the operator can hold the top plate 5 and pull it upwards, and the positioning rod 7 will move upwards together. At this time, the telescopic rod 4 is in a stretched state, and the spring 6 is under force and deformed, and is in a stretched state. When the positioning rod 7 is separated from the positioning groove, the discharge frame 2 will be in an unrestricted state. Then, the discharge frame 2 can be rotated with the help of the two handles 8 to remove it and replace the discharge frame 2 with a discharge groove of different shapes. Through the above structure, the discharge frame 2 can be quickly replaced to adapt to the manufacturing of different plastic particles.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
