As a result, the heating of the materials is uneven, which may cause some parts to be overheated or insufficiently heated, resulting in quality problems.

[0004] Therefore, it is necessary to design a heating and drying component for an injection molding machine to solve the above problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Referring to Figures 1 - 3 , a heating and drying component for an injection molding machine, comprising a bracket 1, on which a drying cylinder 2 is rotatably installed. Both ends of the drying cylinder 2 are fixed with rotating shafts, and both rotating shafts are rotatably installed on the bracket 1. An opening is provided on one of the rotating shafts, and an installation pipe 5 is fixed in the opening. A motor 3 is installed on the bracket 1, and one of the rotating shafts is in transmission connection with the output shaft of the motor 3. One end of the installation pipe 5 extends into the interior of the drying cylinder 2, and the installation pipe 5 and the drying cylinder 2 are coaxially arranged. A filter screen is fixed at the end of the installation pipe 5 located inside the drying cylinder 2. The other end of the installation pipe 5 is installed with a rotary joint 6. A heat source 4 is installed on the bracket 1, and a heat supply pipe is connected to the heat source 4, and one end of the heat supply pipe is connected to the rotary joint 6. The heat source 4 is used to heat the materials in the drying cylinder 2;

[0021] A partition component is arranged inside the drying cylinder 2. The partition component includes a partition plate 71, an opening 72, a rotating plate 73, a slot 74, a spring 75, a connecting rod 76, a magnetic block 77 and an electromagnet 78. The partition plate 71 is fixed on the inner surface of the drying cylinder 2. The opening 72 is provided on the partition plate 71. The rotating plate 73 is rotatably installed on the partition plate 71, and the rotating plate 73 is arranged opposite to the opening 72. The slot 74 is provided at one end of the rotating plate 73. The connecting rod 76 is slidably connected in the slot 74. One end of the spring 75 is connected to the slot 74, and the other end is connected to the connecting rod 76. One end of the connecting rod 76 extends outside the slot 74 and is fixedly connected to the magnetic block 77. The magnetic block 77 is made of a magnetic material. The electromagnet 78 is installed on the rotating plate 73; A control component is arranged on the bracket 1. The control component includes a magnetic block 81, a fixing frame 82 and a magnetic control switch 83. The magnetic block 81 is fixed on the outer surface of the drying cylinder 2. The fixing frame 82 is fixed on the bracket 1. The magnetic control switch 83 is installed on the fixing frame 82. The magnetic control switch 83 is electrically connected to the electromagnet 78. Under the control of the control component, the materials will periodically fall through the opening 72, which makes the materials constantly tumble in the drying cylinder 2, avoiding the situation that the materials piled up inside cannot be fully heated.

[0022] The specific working principle of the present utility model is as follows:

[0023] The staff puts the materials into the drying cylinder 2 and starts the motor 3. When the motor 3 operates, it can drive the drying cylinder 2 to rotate. At the same time, the staff starts the heat source 4. The heat source supplies hot air into the interior of the drying cylinder 2 through the installation pipe 5. The heat supply pipe on the heat source 4 is connected to the installation pipe 5 through the rotary joint 6, which enables relative rotation between the heat supply pipe and the installation pipe 5;

[0024] In the initial state, the partition plate 71 is in a horizontal position, the rotating plate 73 is located on the top surface of the partition plate 71, the electromagnet 78 is in an energized state and attracts the attracting block 77. At this time, the position of the rotating plate 73 is fixed and blocks the opening 72. In addition, the material is located below the partition plate 71, and the magnetic block 81 is located at a position far from the magnetic control switch 83. When the drying cylinder 2 rotates, under the action of the partition plate 71, the material will rotate with the drying cylinder 2. When the partition plate 71 rotates 180°, the magnetic block 81 just rotates to a position close to the magnetic control switch 83. At this time, the electromagnet 78 will be powered off and no longer attract the attracting block 77. At this time, the rotating plate 73 will rotate under the action of gravity, and the material located on the partition plate 71 will fall to the bottom of the drying cylinder 2 through the opening 72. Along with the continuous rotation of the drying cylinder 2, when the partition plate 71 returns to its original position, the magnetic block 81 is far from the magnetic control switch 83 again. Only when the magnetic block 81 is close to the magnetic control switch 83, the rotating plate 73 will open. Based on the above process, under the control of the control component, the material will periodically fall through the opening 72, which makes the material constantly tumble in the drying cylinder 2, avoiding the situation that the material accumulated inside cannot be fully heated;

[0025] The specific control method of the magnetic control switch 83 for the electromagnet 78 is not an innovative part of this technical solution and is not shown in the figure, so no more details will be described here.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
