Description

Technical Field

[0001] This utility model belongs to the field of powder coating preparation technology, specifically relating to an extrusion screw for producing powder coatings. Background Technology

[0002] In the production of powder coatings, extrusion is required for better processing. The extrusion screw is an important component. The extrusion screw is a cylinder with helical grooves cut on its outer surface or a cone with conical helical grooves cut on its outer surface. Extrusion screws are mostly used in plastic molding equipment.

[0003] For example, Chinese Patent (Publication No.: CN202321914635.3) discloses an extrusion screw for producing powder coatings. This extrusion screw, although containing a connector and a connecting rod, has a rod body connected to one side of the connector, and a helical block installed on the outer side of the rod body. When two helical rods of different shapes need to be quickly connected, a first protrusion on one side of the connecting rod can be aligned with one side of the rod body, and a push rod can be pushed downwards. The push rod moves downwards, limiting the first protrusion and thus fixing the first protrusion in place. On one side of the rod body, the push rod is reset by a movable spring, limiting the push rod and allowing the connecting rod to be more stably connected to the rod body. The two helical rods of different shapes improve the extrusion conveying effect. However, the operation is relatively complicated and inconvenient for users. Multiple springs are prone to getting tangled when the screw rotates, affecting the use of the device. In addition, there is a certain gap between the push rod and the screw body during connection, which can easily cause powder coating to enter and affect the use of the equipment. Therefore, an extrusion screw for producing powder coating is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an extrusion screw for producing powder coatings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an extrusion screw for producing powder coatings, comprising a drive motor and a fixing assembly. The output end of the drive motor is provided with an extrusion screw, and a spiral block is provided on the outer side of the extrusion screw. One end of the extrusion screw is provided with a fixing rod, and the fixing rod contains a fixing assembly. A sealing ring is provided between the two extrusion screws. The fixing assembly includes a micro motor, a turntable, a movable groove, a fixed plate, a limiting groove, a buckle, and a connecting rod. The output end of the micro motor is provided with a turntable. A movable groove is provided on one side of the turntable. A fixed plate is provided on one side of the turntable. A limiting groove is provided on one side of the fixed plate. A buckle is provided inside the limiting groove. A connecting rod is provided on one side of the buckle. One end of the connecting rod is connected to the movable groove.

[0006] In a preferred embodiment, one inner side of the fixing rod is fixedly connected to the fixing plate, and the other inner side of the fixing rod is fixedly connected to the micro motor.

[0007] In a preferred embodiment, the number of movable slots is five, and the connecting rod is slidably connected to the movable slots.

[0008] In a preferred embodiment, the extrusion screw has sealing grooves at both ends, and the sealing grooves are connected to sealing rings, which are made of rubber.

[0009] In a preferred embodiment, a fixing groove is provided at the other end of the extrusion screw, and a retaining groove is provided on the inner wall of the fixing groove. There are five retaining grooves, and the retaining grooves are connected to the corresponding buckles.

[0010] In a preferred embodiment, the movable slots are inclined, and the angle between the five movable slots is 72°.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention, through its fixed assembly, allows users to easily connect two extrusion screws of different shapes, improving the extrusion and conveying effect of powder coatings and preventing internal blockage that could affect machine operation. By controlling a micro-motor to drive a turntable, five connecting rods move through a movable slot on one side of the turntable, causing five clips to separate from and move out of the limiting slots, inserting into the corresponding slots. Since the clips are located in the limiting slots on one side of the fixed plate, they can move within these slots. Once the clips are inserted into the slots, the micro-motor is turned off, completing the connection of the two extrusion screws. This eliminates the need for repeated manual operation, greatly simplifying the user experience. Furthermore, by providing sealing grooves at both ends of the extrusion screws and placing sealing rings within these grooves during connection, the connection point of the two extrusion screws can be sealed effectively.

[0013] This invention, by setting the angle between the five movable slots to 72°, allows the movable slots to be inclined, which facilitates the movement of the buckles within the limiting slots when they move through the movable slots via the connecting rod, and ensures that the displacement of the five buckles is the same, thereby better connecting and fixing the two extrusion screws.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Please see Figure 1-7This utility model provides an extrusion screw for producing powder coatings, including a drive motor 1 and a fixing assembly 5. The output end of the drive motor 1 is provided with an extrusion screw 2. A spiral block 3 is provided on the outer side of the extrusion screw 2. A fixing rod 4 is provided at one end of the extrusion screw 2. The fixing assembly 5 is located inside the fixing rod 4. A sealing ring 6 is provided between the two extrusion screws 2. The fixing assembly 5 includes a micro motor 501, a turntable 502, a movable groove 503, a fixed plate 504, a limiting groove 505, a buckle 506, and a connecting rod 507. The output end of the micro motor 501 is provided with a turntable 502. A movable groove 503 is opened on one side of the turntable 502, and a fixed plate 504 is provided on one side of the turntable 502. A limiting groove 505 is provided on one side of 504. A buckle 506 is provided inside the limiting groove 505. A connecting rod 507 is provided on one side of the buckle 506. One end of the connecting rod 507 is connected to the movable groove 503. The turntable 502 is driven to rotate by the micro motor 501. Thus, the five connecting rods 507 can be moved through the movable groove 501 on one side of the turntable 502, thereby causing the five buckles 506 to separate in the limiting groove 505, move out of the limiting groove 505, and insert into the slot 8. Since the buckle 506 is set in the limiting groove 505 on one side of the fixed plate 504, the buckle 506 can move in the limiting groove 505 and insert into the slot 8.

[0025] One side of the inside of the fixing rod 4 is fixedly connected to the fixing plate 504, and the other side of the inside of the fixing rod 4 is fixedly connected to the micro motor 501.

[0026] There are five movable slots 503, and the connecting rod 507 is slidably connected to the movable slots 503.

[0027] The two ends of the extrusion screw 2 are provided with sealing grooves 9, which are connected to the sealing ring 6, which is made of rubber.

[0028] The other end of the extrusion screw 2 is provided with a fixing groove 7, and the inner wall of the fixing groove 7 is provided with a slot 8. There are five slots 8, and the slots 8 are connected to the buckles 506.

[0029] The movable groove 503 is inclined, and the angle between the five movable grooves 503 is 72°. By setting the angle between the five movable grooves 503 to 72°, the movable grooves 503 are inclined, which facilitates the movement of the buckle 506 within the limiting groove 505 when it moves inside the movable groove 503 via the connecting rod 507, and keeps the displacement of the five buckles 506 the same.

[0030] The working principle and usage process of this utility model are as follows: First, the sealing ring 6 is placed in the sealing groove 9 at one end of the fixing groove 7 of one of the extrusion screws 2. Then, the fixing rod 4 of the other extrusion screw 2 is inserted into the fixing groove 7 of the extrusion screw. Finally, the micro motor 501 is controlled to drive the turntable 502 to rotate, so that the five connecting rods 507 can be moved through the movable groove 501 opened on one side of the turntable 502. This causes the five buckles 506 to separate in the limiting groove 505, move out of the limiting groove 505, and insert into the slot 8. Since the buckles 506 are set in the limiting groove 505 opened on one side of the fixed plate 504, the buckles 506 can move in the limiting groove 505, so that the buckles 506 are inserted into the slot 8, and the sealing ring 6 is connected to the sealing groove at one end of the fixing rod 4 of the extrusion screw 2, thereby completing the connection of the two extrusion screws 2.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
