Description

Technical Field

[0001] The invention relates to the technical field of injection molding, in particular to a feeding system for an injection molding workshop. Background Art

[0002] In the injection molding production process, the feeding of raw materials is a key link. The screw feeder is a commonly used feeding method. The screw feeder drives the screw to rotate through the motor. The blades on the screw push the material to move upward along the spiral channel, thereby conveying the material to a certain height. When conveying at an angle, the friction between the material and the spiral blades and the casing is relied on to overcome the gravity of the falling material to achieve transportation.

[0003] For some injection molding raw materials with high water content, blockage is prone to occur during the transportation process, which will not only lead to low feeding efficiency and affect the continuity of the entire injection molding production, but may also cause equipment failure due to blockage, increase maintenance costs and downtime. Moreover, when blockage occurs, the existing feeding system lacks an effective cleaning and unblocking mechanism, and it is difficult to solve the problem quickly and conveniently. Manual intervention is often required, which consumes a lot of manpower and time. In addition, there is no appropriate treatment method for the blocked raw materials that are cleaned out, and they can usually only be discarded, which undoubtedly increases production costs and waste of raw materials.

[0038] The present application is further described in detail below through drawings and examples.

[0039] Reference Figures 1 to 7 The embodiment of the present application provides a feeding system for an injection molding workshop, including a feeding pipe 1, a feeding assembly 2 is arranged between the inside and outside of the feeding pipe 1, an auxiliary assembly 3 is arranged at the bottom of the feeding pipe 1, a connecting assembly 4 is arranged between the feeding assembly 2 and the auxiliary assembly 3, the feeding assembly 2 includes an external box 21 and a spiral conveying rod 22, the spiral conveying rod 22 is rotatably connected to the inside of the feeding pipe 1, the external box 21 is fixedly installed on the left side of the feeding pipe 1, and the right inner wall of the external box 21 is rotatably connected to a first rotating rod 25, the first rotating rod The right end of the rod 25 movably passes through the interior of the external box 21 and the feed pipe 1 and is fixedly connected to the spiral conveying rod 22. The left ends of the first rotating rod 25 and the spiral conveying rod 22 are both slidably connected to the left side walls of the external box 21 and the feed pipe 1. The left inner wall of the external box 21 is rotatably connected to the second rotating rod 28. The right end of the second rotating rod 28 is fixedly installed with a second crown gear 27. The left end of the first rotating rod 25 is fixedly installed with a first crown gear 26. The second crown gear 27 and the first crown gear 26 are meshed with each other.

[0040] The motor 5 is fixedly installed on the left side of the external box 21, and the output end of the motor 5 is movable through the interior of the external box 21 and fixedly connected to the second rotating rod 28. The upper hopper 6 is fixedly installed on the upper left side of the external box 21, and the first discharge port 9 is fixedly installed on the lower right side of the feeding pipe 1. A fixed ring 29 is fixedly installed inside the external box 21, and a rotating ring 210 is rotatably connected to the left side of the fixed ring 29. A spring 211 is fixedly installed between the rotating ring 210 and the first crown gear 26. An electric push rod 212 is fixedly installed on the left side of the rotating ring 210, and the output end of the electric push rod 212 is attached to the right side of the first crown gear 26. The electric push rod 212 is in contact with the first crown gear 26 but not connected. A rotating block 23 is rotatably connected to the inner wall of the right side of the feeding pipe 1, and a square rod 24 is fixedly installed on the left side of the rotating block 23. The square rod 24 is inserted into the right side end of the spiral conveying rod 22, and the cross section of the square rod 24 is square.

[0041] In this embodiment, when the injection molding raw material is fed, the raw material is placed inside the feeding hopper 6, the second rotating rod 28 is driven to rotate by starting the motor 5, and the first rotating rod 25 is driven to rotate by the first crown gear 26 and the second crown gear 27. The rotation of the first rotating rod 25 can drive the spiral conveying rod 22 to rotate, and the material entering the inside of the feeding pipe 1 can be transported by the rotation of the spiral conveying rod 22. The transported material is discharged to the inside of the feeding port of the injection molding equipment through the first discharge port 9, so as to realize the feeding of the injection molding raw material. When the first crown gear 26 rotates, the spring 211 drives the rotating ring 210 to rotate on the side of the fixed ring 29, and the rotating ring 210 and the fixed ring 29 ensure that the first crown gear 26 is supported without affecting the rotation of the first crown gear 26.

[0042] When the injection molding raw material inside the feeding pipe 1 is blocked, the raw material with a high water content is easy to be blocked, and the motor 5 rotates in the reverse direction. When the motor 5 rotates forward, the second crown gear 27 engages and drives the first crown gear 26 to rotate. When the motor 5 rotates in the reverse direction, the teeth of the second crown gear 27 rotates and squeezes the teeth of the first crown gear 26, and the first crown gear 26 moves to the right. After squeezing, the spring 211 is compressed. When the teeth of the second crown gear 27 pass over the teeth of the first crown gear 26, the first crown gear 26 is reset under the action of the spring 211, so that when the motor 5 is reversed, the first crown gear 26 moves back and forth in a straight line, thereby driving the spiral conveying rod 22 to swing left and right through the first rotating rod 25. The raw material adhering to the inner wall of the feeding pipe 1 can be scraped and cleaned by the left and right swing of the spiral conveying rod 22, thereby achieving the effect of conveniently cleaning the blocked raw material, and when the spiral conveying rod 22 reciprocates, the square rod 24 supports the spiral conveying rod 22, ensuring that the spiral conveying rod 22 can rotate and verify the square movement of the square rod 24;

[0043] After the spiral conveying rod 22 reciprocates for a period of time, the electric push rod 212 is started, and the output end of the electric push rod 212 squeezes the first crown gear 26 on the left side, so that the first crown gear 26 can be squeezed and fitted to the right side of the second crown gear 27. At this time, when the motor 5 is reversed, since the first crown gear 26 and the second crown gear 27 are tightly fitted, the second crown gear 27 can still drive the first crown gear 26 to rotate when it rotates. At this time, the spiral conveying rod 22 is in a reverse state, and the reverse state can reversely convey the cleaned blocked raw materials. At this time, the solenoid valve 8 is opened synchronously to discharge the reversely conveyed blocked raw materials through the connecting pipe 7, thereby achieving the purpose of guiding the discharge of the cleaned blocked impurities.

[0044] Reference Figures 1 to 7 In one aspect of the present embodiment, the auxiliary assembly 3 includes an auxiliary box 31, a connecting pipe 7 is fixedly installed between the top of the auxiliary box 31 and the feeding pipe 1, a solenoid valve 8 is fixedly installed at the connection between the connecting pipe 7 and the feeding pipe 1, the connecting pipe 7 is located below the upper hopper 6, and a second discharge port 32 is fixedly installed at the bottom of the right end of the auxiliary box 31. Two conveying rollers 33 are rotatably connected inside the auxiliary box 31, a conveying belt 34 is wound between the two conveying rollers 33, a conveying plate 35 is fixedly installed at the outer end of the conveying belt 34, and the outer end of the conveying plate 35 is attached to the inner top of the auxiliary box 31. The second discharge port 32 is located on the left side of the first discharge port 9, and the second discharge port 32 has the same inclination angle as the first discharge port 9.

[0045] The connecting assembly 4 includes a first bevel gear 41, which is fixedly mounted on the outside of the second rotating rod 28. A protective shell 43 is fixedly mounted on the side wall of the external box 21, a one-way coupling is fixedly mounted inside the protective shell 43, a second bevel gear 42 is fixedly mounted on the front of the one-way coupling through a rotating shaft, and the second bevel gear 42 is meshed with the first bevel gear 41. A pulley 44 is fixedly mounted on the back of the one-way coupling through a rotating shaft, an extended rotating shaft 46 is rotatably connected to the back of the auxiliary box 31, a pulley 44 is fixedly mounted on the back of the extended rotating shaft 46, a belt 45 is wound between the two pulleys 44, and the front of the extended rotating shaft 46 movably penetrates the inner wall of the auxiliary box 31 and is fixedly connected to the left conveying roller 33.

[0046] In this embodiment, when the motor 5 rotates forward, the second rotating rod 28 drives the first bevel gear 41 to rotate, and the first bevel gear 41 drives the second bevel gear 42 to rotate. The rotation direction of the second bevel gear 42 is controlled by the one-way coupling to ensure that it cannot drive the rear pulley 44 to rotate. When the motor 5 is reversed, the second bevel gear 42 can drive the pulley 44 to rotate, and the rotation of the pulley 44 can drive the extension shaft 46 to rotate through the belt 45. The rotation of the extension shaft 46 can drive the inner conveying roller 33 to rotate, and the rotation of the conveying roller 33 can drive the outer conveying plate 35 to move. By moving the conveying plate 35, the blocked raw material that has been cleaned and entered into the auxiliary box 31 through the connecting pipe 7 can be transported, and during transportation, the heating device inside the auxiliary box 31 is started, and the blocked raw material can be heated and dried by the heating device, and discharged into the feeding port of the injection molding machine through the second discharge port 32, thereby realizing the cleaning, heating and drying of the raw material with a high water content that is easy to clog and then passing it into the injection molding machine again, preventing the raw material from being blocked again in the injection molding machine.

[0047] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0048] Working principle: When the injection molding raw material is fed, the raw material is placed inside the feeding hopper 6, the second rotating rod 28 is driven to rotate by starting the motor 5, and the first rotating rod 25 is driven to rotate by the first crown gear 26 and the second crown gear 27. The rotation of the first rotating rod 25 can drive the spiral conveying rod 22 to rotate, and the spiral conveying rod 22 can transport the material entering the feeding pipe 1. The transported material is discharged to the feeding port of the injection molding equipment through the first discharge port 9, so as to realize the feeding of the injection molding raw material. When the first crown gear 26 rotates, the spring 211 drives the rotating ring 210 to rotate on the side of the fixed ring 29, and the rotating ring 210 and the fixed ring 29 ensure that the first crown gear 26 is supported without affecting the rotation of the first crown gear 26.

[0049] When the injection molding raw material inside the feeding pipe 1 is blocked, the raw material with a high water content is easy to be blocked, and the motor 5 rotates in the reverse direction. When the motor 5 rotates forward, the second crown gear 27 engages and drives the first crown gear 26 to rotate. When the motor 5 rotates in the reverse direction, the teeth of the second crown gear 27 rotates and squeezes the teeth of the first crown gear 26, and the first crown gear 26 moves to the right. After squeezing, the spring 211 is compressed. When the teeth of the second crown gear 27 pass over the teeth of the first crown gear 26, the first crown gear 26 is reset under the action of the spring 211, so that when the motor 5 is reversed, the first crown gear 26 moves back and forth in a straight line, thereby driving the spiral conveying rod 22 to swing left and right through the first rotating rod 25. The raw material adhering to the inner wall of the feeding pipe 1 can be scraped and cleaned by the left and right swing of the spiral conveying rod 22, thereby achieving the effect of conveniently cleaning the blocked raw material, and when the spiral conveying rod 22 reciprocates, the square rod 24 supports the spiral conveying rod 22, ensuring that the spiral conveying rod 22 can rotate and verify the square movement of the square rod 24;

[0050] After the spiral conveying rod 22 reciprocates for a period of time, the electric push rod 212 is started, and the output end of the electric push rod 212 squeezes the first crown gear 26 on the left, so that the first crown gear 26 can be squeezed and fitted to the right side of the second crown gear 27. At this time, when the motor 5 is reversed, the first crown gear 26 and the second crown gear 27 are tightly fitted, so that the second crown gear 27 can still drive the first crown gear 26 to rotate when it rotates. At this time, the spiral conveying rod 22 is in a reverse state, and the reverse state can reversely transport the blocked raw materials after cleaning. At this time, the solenoid valve 8 is opened synchronously to discharge the blocked raw materials transported in the reverse direction through the connecting pipe 7, thereby achieving the purpose of guiding the discharge of the blocked impurities after cleaning; when the motor 5 rotates forward, the second rotating rod 28 drives the first bevel gear 41 to rotate, and the first bevel gear 41 drives the second bevel gear 42 to rotate, and the second bevel gear 4 The rotation direction of the motor 2 is controlled by the one-way coupling to ensure that it cannot drive the rear pulley 44 to rotate. When the motor 5 is reversed, the second bevel gear 42 can drive the pulley 44 to rotate. The rotation of the pulley 44 can drive the extension shaft 46 to rotate through the belt 45. The rotation of the extension shaft 46 can drive the inner conveying roller 33 to rotate. The rotation of the conveying roller 33 can drive the outer conveying plate 35 to move. The movement of the conveying plate 35 can transport the blocked raw materials that have been cleaned and entered into the auxiliary box 31 through the connecting pipe 7. During transportation, the heating device inside the auxiliary box 31 is started. The blocked raw materials can be heated and dried by the heating device and discharged into the feeding port of the injection molding machine through the second discharge port 32, thereby realizing the cleaning, heating and drying of the raw materials with high water content that are easy to clog and then passing them into the injection molding machine again, preventing the raw materials from being blocked again in the injection molding machine.
