DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] like Figure 1 As shown, an extrusion molding device includes an extruder 1 and a cleaning brush 2. A workbench 3 is provided in the extruder 1. A cavity is provided in the workbench 3. An outlet 4 is provided on the side wall of the workbench 3. The outlet 4 is connected to the cavity. Two parallel movement holes 5 are also provided on the side wall of the workbench 3. The lengths and widths of the two movement holes 5 are consistent. The two movement holes 5 are also connected to the cavity. A slide rod 6 is slidably connected in one of the movement holes 5. A spring 9 is fixedly connected to the side wall of the slide rod 6 at one end facing away from the outlet 4. The other end of the spring 9 is fixedly connected to the side wall of the cavity. The force applied by the spring 9 to the slide rod 6 will cause the slide rod 6 to drive the cover plate 8 to always be located in front of the outlet 4.

[0020] A lower rack 7 is slidably connected in the other moving hole 5. The lower rack 7 is located below the slide rod 6. At the same time, the lower rack 7 exceeds one end of the slide rod 6. Therefore, the rotation of the first gear 10 and the first pillar 16 will not affect the movement of the slide rod 6. The slide rod 6 and the lower rack 7 are fixedly connected with a cover plate 8 on the side away from the cavity. The cover plate 8 is located in front of the outlet 4.

[0021] Reference Figure 2 and Figure 3 A pushing mechanism for pushing out the cleaning brush 2 is installed in the cavity, and the pushing mechanism includes a first gear 10, a first transmission wheel 11, a second transmission wheel 12, a second gear 13, a side rack 14 and a placement box 15. The bottom wall of the cavity is rotatably connected with a first pillar 16 and a second pillar 17. The first pillar 16 and the second pillar 17 are exactly the same, but their positions are different. Two support plates 18 are fixedly connected to the side wall of the cavity, and the top of the first pillar 16 and the top of the second pillar 17 are rotatably connected to the bottom walls of the two support plates 18 respectively.

[0022] The first gear 10 is fixedly mounted on the outer wall of the first pillar 16, the second gear 13 is fixedly mounted on the outer wall of the second pillar 17, the first transmission wheel 11 is also fixedly mounted on the outer wall of the first pillar 16 and is located above the first gear 10, the first gear 10 is meshed with the lower rack 7, the second transmission wheel 12 is fixedly mounted on the outer wall of the second pillar 17 and is located above the second gear 13, and the first transmission wheel 11 and the second transmission wheel 12 are driven by a conveyor belt. The side rack 14 is fixedly connected to the side wall of the placement box 15, and the side rack 14 is located in the rear half of the placement box 15, so when most of the placement box 15 extends out of the outlet 4, the side rack 14 is still meshed with the second gear 13, and the side rack 14 is meshed with the second gear 13, the cleaning brush 2 is located in the placement box 15, the placement box 15 is facing the outlet 4, the width of the placement box 15 is consistent with the width of the outlet 4, and the height of the bottom of the placement box 15 is also consistent with the height of the bottom of the outlet 4.

[0023] The working principle is as follows: when the staff needs to clean the extruder 1, they can slide the cover plate 8 from the side so that the slide rod 6 and the lower rack 7 slide in the moving hole 5, and then the lower rack 7 drives the first gear 10 to rotate, so the first transmission wheel 11 fixed on the first pillar 16 will also drive the second transmission wheel 12 to rotate, and then the second gear 13 will rotate at the same time, and the side rack 14 meshing with the second gear 13 will drive the placement box 15 to move outward, so the placement box 15 will drive the cleaning brush 2 to move toward the opened outlet 4, making it convenient for the staff to take out the cleaning brush 2 for cleaning.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
