Description

Technical Field

[0001] This utility model relates to the technical field of injection molding machines, specifically to a feeding anti-blocking mechanism for injection molding machines. Background Technology

[0002] An injection molding machine is a mechanical device used to produce plastic parts. Its main function is to inject molten plastic into a mold, where it cools and solidifies, ultimately forming a plastic product with the desired shape and size.

[0003] According to Chinese Patent No. CN219076349U, a feeding mechanism for an injection molding machine includes a feeding cylinder. The inner wall of the feeding cylinder has a groove, and an outer ring plate is inserted into the inner wall of the groove. An upper ring plate is fixedly installed on the outer side of the outer ring plate. A scraper is fixedly installed on the lower surface of the upper ring plate. A connecting plate is fixedly installed on the inner wall of the upper ring plate. A center plate is fixedly installed at the other end of the connecting plate. A slot is formed on the upper surface of the center plate, and a locking block is inserted into the slot.

[0004] In the above solution, a rotating stirring rod is used to stir the plastic particles in the device. However, the above solution still has the following disadvantages: when the stirring rod is stirring, the plastic particles will fall naturally under the action of gravity, and the stirring rod can only play a stirring role. This may increase the probability of blockage due to the accumulation of plastic particles at the bottom of the device. Utility Model Content

[0005] The purpose of this invention is to provide a feeding anti-clogging mechanism for injection molding machines, in order to solve the problem that the stirring rod can only play a stirring role, and the probability of clogging may increase due to the accumulation of plastic particles at the bottom of the device.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a feeding anti-blocking mechanism for an injection molding machine, comprising a housing with two first connecting holes on one side of the lower part of the housing, wherein a first helical blade is rotatably disposed inside one of the first connecting holes, and a second helical blade is rotatably disposed inside the other first connecting hole; a first mounting plate is connected to the outer wall of the lower part of the housing, and a first servo motor and a second servo motor are respectively connected to the first mounting plate; one end of the first helical blade is connected to the output end of the first servo motor, and one end of the second helical blade is connected to the output end of the second servo motor; the lower inner wall of the housing is a slope.

[0007] Preferably, a second connecting hole is provided on both the left and right sides of the box body, and an installation rod is rotatably installed inside the second connecting hole, and a plurality of stirring rods are connected to the installation rod.

[0008] Preferably, a second mounting plate is connected to one outer wall of the housing, a drive motor is connected to the second mounting plate, and one end of the mounting rod is connected to the output end of the drive motor.

[0009] Preferably, the interior of the housing has two heating slots, and heating elements are installed inside the two heating slots.

[0010] Preferably, the outer wall of the box has a plurality of fixing holes, and a mounting bracket is connected inside the fixing holes, and a plurality of magnetic strips are connected to the mounting bracket.

[0011] Preferably, a discharge chute is provided on the lower side of the box body.

[0012] Compared with existing technologies, the feeding anti-blocking mechanism of an injection molding machine that adopts the above technical solution has the following beneficial effects:

[0013] First, during operation, the operator starts the first and second servo motors and the drive motor. The first and second servo motors drive the first and second helical blades respectively, while the drive motor rotates the mounting rod to allow the equipment to idle and check for any safety issues. After confirming that everything is in order, the operator pours plastic granules into the box from above. Then, the first and second servo motors are started. The first servo motor drives the first helical blade to rotate clockwise, and the second servo motor drives the second helical blade to rotate counterclockwise. This accelerates the entry of the plastic granules into the injection molding machine. The rotation of the double helical blades effectively feeds the plastic granules into the injection molding machine, increasing the conveying speed and thus improving production efficiency. If plastic granules become stuck in the discharge chute, stop feeding plastic granules into the machine, turn off the first and second servo motors, and start the first and second servo motors. The first servo motor drives the first spiral blade to rotate counterclockwise, and the second servo motor drives the second spiral blade to rotate clockwise. The reverse rotation brings the plastic granules stuck in the discharge chute back into the machine, thus solving the blockage problem and reducing downtime. When the plastic granules blocking the discharge chute are removed, turn off the running first and second servo motors, and then continue feeding plastic granules into the machine. Start the first and second servo motors again. The first servo motor drives the first spiral blade to rotate clockwise, and the second servo motor drives the second spiral blade to rotate counterclockwise. This speeds up the entry of plastic granules into the injection molding machine and reduces the probability of blockage during use.

[0014] Second, during use, when plastic granules clump together, the operator starts the drive motor. The drive motor rotates the mounting rod, which in turn rotates the stirring rod, breaking up the clumps of plastic granules. This helps prevent material from accumulating inside the chamber or clogging the discharge chute. The heating elements inside the chamber remove moisture from the plastic granules. Preheating and drying the plastic granules using these internal heating elements reduces their moisture content, creating more ideal conditions for the subsequent injection molding process.

[0015] Thirdly, during use, the magnetic strips inside the housing attract metal impurities such as iron filings mixed in with the plastic granules. If these metal impurities enter the injection molding machine directly without treatment, they may cause surface defects in the product, affect product strength, or even damage the precision components of the injection molding machine. The magnetic strips effectively separate these metal impurities, ensuring that the plastic granules entering the injection molding machine are pure and free of impurities, thereby improving the quality of the final product.

[0023] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1-6As shown, a feeding anti-blocking mechanism for an injection molding machine includes a housing 1. Two first connecting holes 2 are opened on the lower side of the housing 1. A first spiral blade 3 is rotatably installed inside one of the first connecting holes 2, and a second spiral blade 4 is rotatably installed inside the other first connecting hole 2. A first mounting plate 5 is connected to the lower outer wall of the housing 1. A first servo motor 6 and a second servo motor 7 are respectively connected to the first mounting plate 5. One end of the first spiral blade 3 is connected to the output end of the first servo motor 6, and one end of the second spiral blade 4 is connected to the output end of the second servo motor 7. The lower inner wall of the housing 1 is inclined, and a discharge groove 18 is opened on the lower side of the housing 1.

[0025] During operation, the operator first starts the first servo motor 6, the second servo motor 7, and the drive motor 12. The first servo motor 6 and the second servo motor 7 drive the first spiral blade 3 and the second spiral blade 4 respectively. The drive motor 12 drives the mounting rod 9 to rotate, allowing the equipment to idle and check for any safety issues. After the check is completed, the operator pours plastic granules into the box 1 from above. Then, the operator starts the first servo motor 6 and the second servo motor 7. The first servo motor 6 drives the first spiral blade 3 to rotate clockwise, and the second servo motor 7 drives the second spiral blade 4 to rotate counterclockwise. This speeds up the entry of the plastic granules into the injection molding machine. The rotation of the double spiral blades effectively feeds the plastic granules into the injection molding machine, increasing the conveying speed and thus improving production efficiency. If plastic granules become stuck in the discharge chute 18, stop pouring plastic granules into the housing 1, turn off the first servo motor 6 and the second servo motor 7, and then start the first servo motor 6 and the second servo motor 7. The first servo motor 6 drives the first spiral blade 3 to rotate counterclockwise, and the second servo motor 7 drives the second spiral blade 4 to rotate clockwise. The reverse rotation brings the plastic granules stuck in the discharge chute 18 back into the housing 1, thus quickly resolving the blockage and reducing downtime. When the plastic granules blocking the discharge chute 18 are removed, turn off the running first servo motor 6 and the second servo motor 7, and then continue pouring plastic granules into the housing 1. Start the first servo motor 6 and the second servo motor 7 again. The first servo motor 6 drives the first spiral blade 3 to rotate clockwise, and the second servo motor 7 drives the second spiral blade 4 to rotate counterclockwise. This speeds up the entry of plastic granules into the injection molding machine and reduces the probability of blockage during use.

[0026] like Figures 1-6As shown, the left and right sides of the box body 1 are provided with second connection holes 8. The second connection holes 8 are rotatably installed with mounting rods 9. Several stirring rods 10 are connected to the mounting rods 9. A second mounting plate 11 is connected to one side of the outer wall of the box body 1. A drive motor 12 is connected to the second mounting plate 11. One end of the mounting rod 9 is connected to the output end of the drive motor 12. Two heating slots 13 are opened inside the box body 1. Heating plates 14 are installed inside the two heating slots 13.

[0027] During use, when plastic granules clump together, the operator starts the drive motor 12. The drive motor 12 rotates the mounting rod 9, which in turn rotates the stirring rod 10, breaking up the clumps of plastic granules. This helps prevent material from accumulating in the housing 1 or clogging the discharge chute 18. The heating element 14 installed inside the housing 1 removes moisture from the plastic granules. Preheating and drying the plastic granules with the heating element 14 reduces the moisture content, creating more ideal conditions for the subsequent injection molding process.

[0028] like Figures 1-6 As shown, a number of fixing holes 15 are provided on the outer wall of the box 1, and a mounting bracket 16 is connected inside the fixing hole 15. A number of magnetic strips 17 are connected to the mounting bracket 16.

[0029] During use, the magnetic strips 17 inside the housing 1 attract metal impurities such as iron filings mixed in with the plastic granules. If these metal impurities enter the injection molding machine directly without treatment, they may cause defects on the product surface, affect the product strength, or even damage the precision parts of the injection molding machine. Through the attraction of the magnetic strips 17, these metal impurities can be separated, ensuring that the plastic granules entering the injection molding machine are pure and free of impurities, thereby improving the quality of the final product.

[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
