[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] This is an injection molding machine used for automotive interiors, such as Figures 1-5 As shown, the device includes a body 1 and a feed pipe 2 fixedly connected to the body 1. A screw 3 is rotatably connected inside the feed pipe 2. A feed nozzle 4 is detachably connected to the end face of the feed pipe 2. The detachable connection of the feed nozzle 4 allows the interior of the feed pipe 2 to communicate with the outside, facilitating the movement and replacement of the fixing plate 7, the fixing plate 8, and the sliding plate 11. The feed pipe 2 has a placement cavity 5 and a placement cavity 6, which are symmetrically arranged along the centerline of the length of the feed pipe 2. A fixing plate 7 is slidably connected inside the placement cavity 5. An adsorption plate 12 with elastic deformation properties is detachably connected to the side of the fixing plate 7 near the screw 3. A fixing plate 8 is slidably connected inside the placement cavity 6. Several adsorption plates 9 are alternately arranged on the side of the fixing plate 8 near the screw 3. The screw 3 is equipped with several heating plates 10. The first adsorption plate 9 and the heating plate 10 have elastic deformation properties. The first fixing plate 7 and the second fixing plate 8 are both arc-shaped and their openings face each other. The arc shape can better fit the surface shape of the screw 3. The first adsorption plate 9, the second adsorption plate 12 and the heating plate 10 with elastic deformation properties can deform during the process of fitting the outer peripheral wall of the screw 3, so that their own shape can fit the screw 3, increasing the contact area of ​​the first adsorption plate 9 and the second adsorption plate 12. The setting of the heating plate 10 can increase the temperature of the surface of the screw 3 and the air inside the feed pipe 2, so that the plastic solidified on the surface of the screw 3 will gradually melt and be absorbed by the first adsorption plate 9 and the second adsorption plate 12, reducing the solid plastic solidified on the threaded part of the screw 3.

[0022] like Figure 4 andFigure 5 As shown, the fixed plate two 8 is provided with a plurality of accommodating cavities 13 corresponding to the heating plates 10, and the accommodating cavities 13 are provided with a plurality of heating wires 14, which are electric heating wires, so as to stably control the temperature released by the heating wires 14 and avoid the phenomenon of thermal damage of the adsorption plate one 9 and the adsorption plate two 12 caused by excessively high temperature. After the material in the conveying pipe 2 is emptied, the screw 3 is slowly rotated, and in the process of rotation, the plurality of heating plates 10 increase the temperature of the air in the conveying pipe 2 and the screw 3, so that the plastic attached to the screw 3 gradually melts, and the melted material is gradually absorbed by the adsorption plate one 9 and the adsorption plate two 12 abutting against the screw 3. The adsorption capacity of the adsorption plate one 9 is increased by the fixed plate one 7 without the heating plates 10. Since the adsorption plate one 9 and the adsorption plate two 12 are provided with synthetic sponges, the more pores in the sponges can accommodate more plastic particles. Since the adsorption plate one 9 and the adsorption plate two 12 always abut against the outer circumferential wall of the screw 3, in the process of rotation of the screw 3, the adsorption plate one 9 and the adsorption plate two 12 have a wiping effect on the surface of the screw 3, thereby increasing the cleaning effect of the surface of the screw 3. Since the adsorption plate one 9, the adsorption plate two 12 and the heating plate 10 have elastic deformation performance, in the process of rotation of the screw 3, they will not collide with each other to cause damage to the structure, thereby prolonging the service life of the structure.

[0023] As shown in Figure 1 , Figure 3 , Figure 4 and Figure 5 , the fixed plate one 7 and the fixed plate two 8 are fixedly connected to the inner wall of the conveying pipe 2 through a plurality of telescopic rods, the telescopic rods are respectively located at the midpoint and both ends of the fixed plate one 7 and the fixed plate two 8, and the telescopic rods are electric telescopic rods. The uniform distribution of the stress positions of the fixed plate one 7 and the fixed plate two 8 is ensured by the setting of the positions of the plurality of telescopic rods. The increase of the length of the telescopic rods will apply a pushing force to the outer circumferential wall of the fixed plate one 7 and the fixed plate two 8, so that the both ends and the middle part of the fixed plate one 7 can simultaneously move towards the screw 3 until abutting against the screw 3. The sliding plate 11 for isolating the screw 3 and the placing cavities one 5 and two 6 is slidably connected in the conveying pipe 2. When the screw 3 needs to be cleaned, the conveying nozzle 4 is detached from the conveying pipe 2, and the sliding plate 11 is detached from the conveying pipe 2 by the operator, so that the fixed plate one 7 and the fixed plate two 8 can move towards the screw 3, and the worker can clean the material fixed on the inner wall of the sliding plate 11, thereby improving the cleaning efficiency and simplifying the cleaning steps.

[0024] As shown in Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, the two ends of the sliding plate 11 are fixedly connected with the magnet block one, the inner wall of the feeding pipe 2 and the side of the feeding nozzle 4 close to the screw 3 are fixedly connected with the magnet block two which is attracted by the magnet block one, the stability of the sliding plate 11 is ensured by the magnetic force, the displacement of the sliding plate 11 after being pressed by the material is avoided, and the fixed plate one 7 and the fixed plate two 8 also provide stable supporting force for the sliding plate 11, so that the stability of the sliding plate 11 is ensured, the fixed plate one 7 and the fixed plate two 8 are detachably connected through the clamping groove and the clamping block, when people need to replace or clean the adsorption plate one 9 and the adsorption plate two 12, the feeding nozzle 4 is first removed, the fixed plate one 7 or the fixed plate two 8 is pulled to make the clamping block slide out of the clamping groove, and then the feeding nozzle 4 and the sliding plate 11 are pulled out of the opening of the feeding pipe 2, so that the convenience of cleaning is ensured.

[0025] Working principle: during the normal working process of the equipment, the fixed plate one 7 and the fixed plate two 8 are located between the inner wall of the feeding pipe 2 and the outer wall of the sliding plate 11, if the screw 3 needs to be cleaned after the working of the equipment is completed, the feeding nozzle 4 is first removed by the worker, and then the sliding plate 11 is pulled out of the feeding pipe 2, at this time, the worker can clean the feeding nozzle 4 and the sliding plate separately, the worker supplies power to make the electric heating wire begin to heat and increase the length of the telescopic rod, the fixed plate one 7 and the fixed plate two 8 move towards the screw 3, until the adsorption plate one 9 and the adsorption plate two 12 tightly fit the outer peripheral wall of the screw 3, at this time, the screw 3 is slowly rotated, the heat generated by the heating plate 10 can be uniformly transmitted to the outer peripheral wall of the screw 3, so that the material solidified in the screw 3 can be melted, the melted material can be gradually absorbed by the adsorption plate one 9 and the adsorption plate two 12, so that the cleaning of the outer peripheral wall of the screw 3 is realized, after the cleaning is completed, the length of the telescopic rod is shortened, and the attraction between the magnet block one and the magnet block two is used to fix the sliding plate 11 and the feeding nozzle 4 again, so that the equipment can work again.
