[0003] However, the existing plastic processing injection molding machine is affected by various factors when in use, and the material is easy to adhere to the inner wall of the feeding port. On the one hand, due to the characteristics of the plastic particles, some plastic materials have certain viscosity, especially at a relatively high processing temperature, the surface of the particles will soften to a certain extent, and it is more likely to adhere to the inner wall of the feeding port.

The material adhering to the inner wall of the feeding port for a long time will cause waste of material, and the adhered material cannot participate in the normal injection molding process. With the passage of time, the amount of accumulated material waste cannot be ignored, which increases the production cost. Secondly, the material at the feeding port cannot smoothly enter the subsequent heating and melting area, resulting in uneven overall feeding, and the material entering the injection molding machine subsequently is difficult to ensure uniform heating when heated, thereby affecting the performance and quality of the product.

[0031] Further comprising a movable assembly 3 for scraping the plastic adhered to the inner wall of the feed inlet 2;

[0032] A moving assembly 4 for accelerating the feeding efficiency of the plastic;

[0033] Firstly, the movable assembly 3 comprises: a fixed frame 31 fixedly installed on the top of the machine body 1, the fixed frame 31 top is fixedly installed with a driving motor 32, the driving motor 32 output shaft surface is fixedly installed with a rotating shaft 33, the rotating shaft 33 is rotatably connected to the bottom of the fixed frame 31, the rotating shaft 33 bottom is fixedly installed with a connecting shaft 34, the connecting shaft 34 bottom is fixedly installed with a connecting block 35, the connecting block 35 outer side is fixedly installed with a telescopic rod 36, the telescopic rod 36 surface is fixedly installed with a sliding block 37, the sliding block 37 outer side is fixedly installed with a scraping rod 38, the connecting block 35 can produce centrifugal force while rotating, realize that the scraping rod 38 is adhered to the inner wall of the feed inlet 2 and rotates.

[0034] Secondly, the rotating shaft 33 surface is slidably connected with a sliding rod 39, the sliding rod 39 surface is fixedly installed with a resisting rod 310, the resisting rod 310 surface is provided with a fixed ring 311, the fixed ring 311 is fixedly installed on the top of the connecting shaft 34, the resisting rod 310 is slidably connected to the top of the connecting shaft 34, the rotating shaft 33 can drive the sliding rod 39 and the resisting rod 310 to reciprocate up and down, realize that the resisting rod 310 resists and pulls the fixed ring 311 to reciprocate up and down.

[0035] ​Further, the connecting block 35 is fixedly installed with a positioning block 312 outside, the sliding block 37 is slidingly connected inside the positioning block 312, the telescopic rod 36 is fixedly installed with a fixed spring 313 on the surface, the connecting block 35 is fixedly installed with a connecting plate 314 outside, and the connecting plate 314 is fixedly installed with a scraping block 315 at the bottom. The fixed spring 313 on the surface of the telescopic rod 36 can be used to reset the telescopic rod 36 under the action of the fixed spring 313 when the driving motor 32 stops, so that the scraping rod 38 is driven to move towards the inside of the scraping block 315,

[0036] In the embodiment, the driving motor 32 is started to drive the rotating shaft 33, the connecting shaft 34, the connecting block 35 and the positioning block 312 to rotate. When the positioning block 312 rotates, the telescopic rod 36 is elongated by centrifugal force, which drives the sliding block 37 to move inside the positioning block 312. When the sliding block 37 slides, the scraping rod 38 is attached to the inner wall of the feed inlet 2, and the plastic adhered to the inner wall of the feed inlet 2 is scraped off, preventing the material from adhering to the inner wall of the feed inlet 2 and causing waste of material. Long-term adhesion will affect the product performance, thereby ensuring the continuity of injection molding production, reducing the waste of material and improving the work efficiency.

[0037] Embodiment 2

[0038] As shown in Figure 5 The moving assembly 4 includes a sliding plate 41 slidingly connected to the inner wall of the feed inlet 2, a pressure plate 42 fixedly installed on the surface of the sliding plate 41, a reciprocating screw rod 43 provided inside the pressure plate 42, the reciprocating screw rod 43 fixedly installed at the bottom of the connecting block 35, and the pressure plate 42 threadedly connected to the surface of the reciprocating screw rod 43.

[0039] Finally, the rotating shaft 33 is provided with a reciprocating sliding groove 330 on the surface, which can be used to realize the reciprocating sliding of the sliding rod 39 up and down when the rotating shaft 33 rotates.

The surface of the positioning block 312 is provided with a groove 3120, which can be used to realize the sliding of the sliding block 37 inside the positioning block 312. The inner side of the scraping block 315 is triangular in cross section, which can be used to improve the scraping effect of the scraping block 315 on the scraping rod 38.

[0040] In this embodiment, through the setting of the moving assembly 4, when the driving motor 32 rotates, the reciprocating screw rod 43 will also rotate, and when the reciprocating screw rod 43 rotates, the pressure plate 42 will slide on the inner wall of the feeding port 2 through the sliding plate 41, and when the pressure plate 42 slides downward, it will resist the processed material in the inside of the feeding port 2, preventing the possibility of plastic particles bridging each other during the feeding process, ensuring the production progress and improving the feeding efficiency.

[0041] The injection molding machine for plastic processing has the advantages that during use, the injection molding process is that the dried plastic particles (polypropylene particles) are conveyed to the injection molding machine through airtight pipelines, and the PP and PC particles are heated to 200 DEG C by using the electric heating system of the injection molding machine, so that the plastic particles can be melted.

[0042] When the shaft 33 rotates, the reciprocating sliding groove 330 formed in the surface of the shaft 33 drives the sliding rod 39 to reciprocate on the surface of the shaft 33, and when the sliding rod 39 slides, the abutting rod 310 slides, and when the abutting rod 310 slides downward, the fixed ring 311 slides downward, so that the remaining movable assembly 3 at the bottom of the fixed ring 311 slides downward, and the scraping effect and area of the scraping rod 38 on the inner wall of the feeding port 2 can be improved.

[0043] When the driving motor 32 stops rotating, the telescopic rod 36 resets under the action of the fixed spring 313, so that the scraping rod 38 and the sliding block 37 reset, the scraping rod 38 moves towards the inner wall of the scraping block 315, and the plastic remaining on the surface of the scraping rod 38 is scraped again by the scraping block 315, so as to fall into the inside of the feeding port 2 for processing, thereby improving the practicability of the injection molding machine and the safety of the processed plastic.

[0044] When the connecting block 35 rotates under the action of the driving motor 32, the reciprocating screw rod 43 will also rotate, and when the reciprocating screw rod 43 rotates, the pressure plate 42 will slide up and down on the inner wall of the feeding port 2 through the sliding plate 41, so that when the pressure plate 42 slides downward, it will resist the processing material in the inside of the feeding port 2, preventing the plastic particles from possibly bridging with each other, that is, forming an arch-shaped structure in the feeding port 2, so that the subsequent particles cannot smoothly fall into the inside of the injection molding machine by their own gravity, causing the bottom end of the feeding port 2 to be blocked, ensuring the production progress and improving the feeding efficiency.
