Description

Technical Field

[0001] This application relates to the technical field of plastic product production, and particularly to a plastic product production device for processing composite plastics. Background Art

[0002] With the continuous development of society and the continuous progress of technology, the technologies related to plastic product production are also constantly improving. Composite plastics have good comprehensive properties. At present, many plastic products are made of composite plastic materials, including plastic films. The packaging plastic films made of composite plastic materials need to be processed by production equipment such as extrusion molding, hot pressing, inflation, and sealing during production.

[0003] Firstly, during the processing of existing plastic product production equipment, a mold release agent is applied to the surface of the mold to reduce the contact area between the plastic parison and the mold during the blow molding process, avoid the adhesion of the plastic parison to the mold, and thus improve the demolding effect. During this process, since the mold release agent needs to be applied to the surface of the mold, for plastic products with complex shapes, such as parts with multiple concave and convex parts or fine structures, it is difficult to ensure that these key parts are fully lubricated, and demolding failure may occur due to local adhesion. Secondly, during the blow molding process, a slit is manually made in a specific position on the plastic parison. To avoid the plastic parison from swelling and bursting, when making the manual slit, the gas will eject the high-temperature plastic fragments from this slit, posing a safety hazard during the blow molding process. Moreover, it is very difficult to ensure that the position of each slit is accurate. If the incision position deviates from the design requirements, it may affect the expansion and molding of the plastic parison during the blow molding process, resulting in problems such as uneven wall thickness and local weakness of the product. Summary of the Invention

[0004] This application provides a plastic product production device for processing composite plastics, which has the advantages of spraying on key parts and uniform spraying to solve the problem of uneven application of the mold release agent.

[0005] To achieve the above object, this application adopts the following technical solution: A plastic product production device for processing composite plastics includes a support frame, the top of the support frame is fixedly connected with an installation top plate, and a conveying component is arranged in the middle of the upper surface of the installation top plate; One side of the top of the support frame is fixedly connected with an installation frame, and a discharging component is arranged inside the installation frame; Two groups of guide columns are fixedly connected inside the support frame. A first fixing block is fixedly sleeved on the outside of one group of the guide columns, and a material clamping component is arranged on one side of the first fixing block; One side of the lower surface of the support frame is fixedly connected with a second connecting plate. Both sides of the top of the second connecting plate are fixedly connected with second driving motors. The output ends of the two second driving motors are fixedly connected with threaded rods. Multiple second fixing blocks are threadedly connected to the outer sides of the two threaded rods. Both sides of the tops of the multiple second fixing blocks are fixedly connected with molds. Spraying assemblies are arranged inside the molds. With the above structure, during operation, the rotation of the second driving motor drives the threaded rod to rotate. The rotation of the threaded rod drives the two molds to move towards each other through the provided opposite threads, enabling the plastic to be blow-molded.

[0006] Preferably, the conveying assembly includes a first mounting block. The first mounting block is fixedly connected to one side of the top of the mounting top plate. One side of the first mounting block is fixedly connected with a conveying column. A first driving motor is fixedly connected inside the first mounting block. The output end of the first driving motor is fixedly connected with a screw conveyor shaft. One side of the top of the conveying column is fixedly connected with a connecting block. The top of the connecting block is fixedly connected with a feed hopper. One side inside the conveying column is fixedly connected with a communicating pipe.

[0007] Preferably, the discharging assembly includes a hydraulic rod. The hydraulic rod is fixedly connected to the middle of the upper surface of the mounting frame. The output end of the hydraulic rod is fixedly connected with multiple connecting shafts. One ends of the multiple connecting shafts are fixedly connected with a first pushing block. A material guiding outer shell is arranged outside the first pushing block. The material guiding outer shell is fixedly connected to the middle of the lower surface of the mounting frame. One end of the conveying column is fixedly connected with the material guiding outer shell. With the above structure, during operation, the screw conveyor shaft spirally conveys the plastic particles, ensuring the stability of the mixing and conveying of the plastic.

[0008] Preferably, the discharging assembly further includes a material blocking column. The material blocking column is arranged in the middle of the inside of the material guiding outer shell. The material blocking column is fixedly connected with the mounting frame. An inner core is arranged inside the material blocking column. The inner core is fixedly connected to the bottom of the upper layer of the mounting frame. A material guiding groove is formed on the outer surface of the inner core. A material guiding column is fixedly connected to the bottom of the inner core. One ends of multiple first springs are fixedly connected to the inside of the material guiding column. The other ends of the multiple first springs are fixedly connected with a first connecting column. One end of the first connecting column is fixedly connected with a sealing block. The first connecting column is slidably connected to the inside of the material guiding column. With the above structure, during operation, when the material flows downward from both sides into the storage bin through the guidance of the material guiding groove, the plastic liquid can flow more smoothly in the storage bin, reducing the bubbles generated due to the disordered liquid flow. At the same time, it can reduce the impact of the plastic liquid during the conveying process and reduce the generation of bubbles.

[0009] Preferably, the material clamping assembly includes a second mounting block fixedly connected to one side of the first fixed block. A sliding plate is movably sleeved outside the second mounting block. A manipulator is fixedly connected to the bottom of the sliding plate. A first connecting plate is fixedly connected to the middle of the lower surface of the manipulator. A notch column is fixedly connected to one side of the first connecting plate. The above structure can drive its movement through the material clamping assembly by means of an external driving source such as a motor and a driving push rod during operation to achieve the clamping work.

[0010] Preferably, both sides of the bottom of the support frame are fixedly connected with support plates. Two support blocks are fixedly connected to the top of each group of support plates. A slide rail is fixedly connected to the top of each group of support blocks. The slide rail is slidably connected to the mold. The above structure can support the slide rail through the support plates and support blocks during operation to ensure that the mold can slide outside the slide rail and at the same time ensure the consistency of the heights of the two slide rails.

[0011] Preferably, the spraying assembly includes a second placement groove opened in the middle of the bottom of one side of the mold. A third connecting plate is fixedly connected to one side of the support frame. An air pump is fixedly connected to the bottom of the third connecting plate. A blow molding pipe is fixedly connected to the top of the air pump. The blow molding pipe penetrates through the third connecting plate and is fixedly connected to the third connecting plate. The above structure can blow air to the plastic preform through the blow molding pipe to prevent the plastic preform from sticking during the discharging process.

[0012] Preferably, the spraying assembly includes a first placement groove opened on one side of the mold. A moving column is slidably connected inside the mold. A top piece is fixedly connected to one end of the moving column. A first fixing ring is fixedly sleeved outside the moving column. One end of a second spring is fixedly connected to one side of the first fixing ring. The other end of the second spring is fixedly connected to a second fixing ring. The second fixing ring is fixedly connected to the mold. A second connecting column is fixedly connected to one side of the second fixing ring. A cam is fixedly connected to one side of the second connecting column. A rotating shaft is rotatably connected to the middle of the cam. The rotating shaft is fixedly connected to the mold. A second push block is fixedly connected to one side of the cam. A multi-headed rod is movably sleeved outside one side of the second push block. A plurality of pistons are fixedly connected to one side of the multi-headed rod. The above structure can enable the multi-headed rod to slide up and down inside the second push block during operation. Thus, when the second push block shifts up and down, the position of the multi-headed rod is ensured not to change. And the lateral displacement of the second push block can push out the multi-headed rod, and when the second push block returns to its original position, it can drive the multi-headed rod to return to its original position.

[0013] Preferably, the spraying assembly includes a liquid storage bin which is arranged on the upper side inside the mold. A diversion groove is formed on one side of the bottom of the liquid storage bin. A plurality of spray heads are fixedly connected inside the liquid storage bin. An annular moving groove is formed inside the liquid storage bin, and the shape of the annular moving groove is adapted to the swinging track of the second push block. With the above structure, during operation, the release agent can be pressed out by the piston and evenly sprayed onto the surface of the plastic preform.

[0014] Preferably, the height of the blow molding pipe is higher than the height of the upper surface of the second placement groove, and the height of the first placement groove corresponds to that of the first connecting plate. With the above structure, during operation, since the height of the blow molding pipe is higher than the height of the upper surface of the second placement groove, the blow molding pipe can be better located inside the blow molding raw material when the mold is closed for blow molding.

[0015] The beneficial effects of the present invention are as follows: During the operation of the present invention, when the mold moves to completely clamp the material, the first connecting plate will be inside the first placement groove. At this time, the first connecting plate will push the top sheets on both sides to both sides, thereby driving the moving column to move backward. The moving column moves backward and drives the second connecting column to move backward. After the second connecting column moves backward, it drives the cam to rotate a certain angle along the rotating shaft. After the rotating shaft rotates, it drives the second push block to move. After the second push block moves, it drives the multi-headed rod and the piston to move forward, pressing out the release agent inside the diversion groove through the spray heads and evenly spraying it on the surface of the plastic preform, thereby preventing the plastic preform from adhering to the mold during the blow molding process, making the demolding process smoother, reducing the time consumed due to difficult demolding, and at the same time, evenly spraying the release agent enables the plastic preform to be successfully formed during the blow molding process, avoiding local thinning or stretching of the product caused by local adhesion, which affects its appearance and normal use.

[0016] In the present invention, by starting the first driving motor to drive the spiral conveying shaft to rotate, the spiral conveying shaft rotates and mixes and conveys the plastic pellet balls forward through the spiral. The plastic pellet balls are heated and liquefied through the pipeline of the conveying column. The liquefied plastic is conveyed to the inside of the material blocking column through the connecting pipe. The liquefied plastic flows downward through the material guiding groove. When the material flows downward from both sides into the inside of the storage bin through the guiding of the material guiding groove, the plastic liquid can flow more smoothly in the storage bin, reducing the bubbles generated due to the disordered liquid flow, and at the same time, it can reduce the impact of the plastic liquid during the conveying process and reduce the generation of bubbles. In the discharging assembly, the material guiding column, the material guiding outer shell and the first push block form a storage cavity inside the material guiding outer shell. The liquefied plastic will accumulate inside the storage bin. When the accumulated plastic reaches the quantity required for product forming, the hydraulic rod is started to drive the first push block to press downward. At this time, the first push block presses downward to press out the material, and at the same time, it will block the space reserved from the material blocking column to the material guiding column, thereby preventing the continuous output of the material and causing unnecessary waste and loss.

[0017] In the present invention, the second drive motor is started to drive the threaded rod to rotate. After the threaded rod rotates to drive the mold to slide relatively along the guide posts and the slide rails, the plastic preform is clamped. During the clamping process, since the air pump at the bottom continuously blows air when the material is discharged, when the mold continuously closes, the plastic preform will continuously expand. At this time, the clamping component moves simultaneously to clamp the top of the material. At this time, since the plastic preform will contact the break column, a notch will be pierced in the plastic preform, which can well avoid the bursting of the plastic preform due to gas swelling during the blow molding process, reduce the internal stress, and can significantly reduce the rejection rate caused by molding defects (such as uneven wall thickness, deformation, cracking, etc.). At the same time, it can also reduce the molding defects caused by uneven plastic flow resistance or uneven preform expansion, thereby improving the production efficiency.

By rotating the second driving motors 34, the threaded rods 35 are driven to rotate. Through the arranged opposite threads, the two groups of molds 32 are driven to move towards each other, and the materials pressed out from the bottom of the discharging assembly are clamped by the clamping assembly. After the clamping is completed, the air pump 39 is started, so that the plastic can be blow-molded.

[0023] Among them, the conveying assembly includes a first mounting block 3. The first mounting block 3 is fixedly connected to one side of the top of the mounting top plate 2. One side of the first mounting block 3 is fixedly connected with a conveying column 4. Inside the first mounting block 3, a first driving motor 5 is fixedly connected. The output end of the first driving motor 5 is fixedly connected with a spiral conveying shaft 6. On one side of the top of the conveying column 4, a connecting block 7 is fixedly connected. On the top of the connecting block 7, a feed hopper 8 is fixedly connected. On one side inside the conveying column 4, a communicating pipe 9 is fixedly connected. In this embodiment, when the first driving motor 5 is started to drive the spiral conveying shaft 6 to rotate, the spiral conveying shaft 6 rotates and mixes and conveys the plastic pellet balls forward through the spiral. The plastic pellet balls are heated and liquefied through the pipeline of the conveying column 4, and the liquefied plastic is conveyed to the inside of the material blocking column 15 through the communicating pipe 9, ensuring the stability of the mixing and conveying of the plastic.

[0024] Among them, the discharging assembly includes a hydraulic rod 11. The hydraulic rod 11 is fixedly connected to the middle of the upper surface of the mounting frame 10. The output end of the hydraulic rod 11 is fixedly connected with multiple groups of connecting shafts 12. One ends of the multiple groups of connecting shafts 12 are fixedly connected with a first pushing block 13. The outside of the first pushing block 13 is provided with a material guiding outer shell 14. The material guiding outer shell 14 is fixedly connected to the middle of the lower surface of the mounting frame 10. One end of the conveying column 4 is fixedly connected with the material guiding outer shell 14. The discharging assembly further includes a material blocking column 15. The material blocking column 15 is arranged in the middle inside the material guiding outer shell 14. The material blocking column 15 is fixedly connected with the mounting frame 10. Inside the material blocking column 15, a core 16 is arranged. The core 16 is fixedly connected to the bottom of the upper layer of the mounting frame 10. A material guiding groove 17 is formed on the outer surface of the core 16. The bottom of the core 16 is fixedly connected with a material guiding column 18. One ends of multiple groups of first springs 19 are fixedly connected to the inside of the material guiding column 18. The other ends of the multiple groups of first springs 19 are fixedly connected with a first connecting column 20. One end of the first connecting column 20 is fixedly connected with a sealing block 21. The first connecting column 20 is slidably connected to the inside of the material guiding column 18.

[0025] The hydraulic rod 11 starts to drive the first push block 13 to press downward. At this time, the first push block 13 presses downward to extrude the material. At the same time, it will block the space reserved by the material blocking column 15 to the material guiding column 18, thus avoiding unnecessary waste caused by the continuous output of the material, avoiding cost increase and unnecessary losses. At the same time, the first push block 13 presses the material downward, and the material presses the sealing block 21, causing the first spring 19 to stretch, driving the first connecting column 20 and the sealing block 21 to move downward, so that the material can be discharged through the bottom of the material guiding housing 14. And because the material will be discharged along the periphery of the sealing block 21, the material presents a hollow cylindrical state during the discharging process. At the same time, the air pump 39 is started to blow air and discharge the material at the same time during the discharging process. Since the blow molding tube 40 is located at the center of the material, the gas will circulate in the center of the material at this time to prevent it from sticking, avoiding affecting the subsequent blow molding. At the same time, the plastic preform is immediately affected by the uniform action of the air flow while being extruded, so that the plastic can be more evenly distributed on the inner wall of the mold, which is conducive to forming a product with uniform wall thickness.

[0026] Among them, the material clamping assembly includes a second mounting block 24. The second mounting block 24 is fixedly connected to one side of the first fixed block 23. A sliding plate 25 is movably sleeved outside the second mounting block 24. A mechanical hand 26 is fixedly connected to the bottom of the sliding plate 25. A first connecting plate 27 is fixedly connected to the middle of the lower surface of the mechanical hand 26. A notch column 28 is fixedly connected to one side of the first connecting plate 27.

[0027] The material clamping assembly is driven to move through an external drive source such as a motor and a driving push rod to realize the clamping work. And during the working process, the plastic preform will come into contact with the notch column 28, thus punching a notch in the plastic preform, which can well avoid the plastic preform from bursting due to gas swelling during the blow molding process, reduce the internal stress, and can significantly reduce the rejection rate caused by forming defects such as uneven wall thickness, deformation, cracking, etc. At the same time, it can also reduce the forming defects caused by uneven plastic flow resistance or uneven preform expansion, thereby improving the production efficiency.

[0028] Among them, two support plates 29 are fixedly connected to both sides of the bottom of the support frame 1. Two support blocks 30 are fixedly connected to the tops of the two groups of support plates 29. A slide rail 31 is fixedly connected to the top of each group of support blocks 30. The slide rail 31 is slidably connected to the mold 32. In this embodiment, the support plates 29 and the support blocks 30 support the slide rail 31 to ensure that the mold 32 can slide outside the slide rail 31, and at the same time ensure the consistency of the heights of the two groups of slide rails 31.

[0029] Among them, the spraying assembly includes a second placement groove 37, which is opened in the middle of the bottom side of the mold 32. One side of the support frame 1 is fixedly connected with a third connecting plate 38. The bottom of the third connecting plate 38 is fixedly connected with an air pump 39. The top of the air pump 39 is fixedly connected with a blow molding pipe 40. The blow molding pipe 40 penetrates through the third connecting plate 38 and is fixedly connected with the third connecting plate 38. The spraying assembly includes a first placement groove 271, which is opened on one side of the mold 32. A moving column 41 is slidably connected inside the mold 32. One end of the moving column 41 is fixedly connected with a top piece 42. The outer side of the moving column 41 is fixedly sleeved with a first fixing ring 43. One end of a second spring 44 is fixedly connected to one side of the first fixing ring 43. The other end of the second spring 44 is fixedly connected with a second fixing ring 45. The second fixing ring 45 is fixedly connected with the mold 32. One side of the second fixing ring 45 is fixedly connected with a second connecting column 46. One side of the second connecting column 46 is fixedly connected with a cam 47. A rotating shaft 48 is rotatably connected to the middle of the cam 47. The rotating shaft 48 is fixedly connected with the mold 32. One side of a second push block 49 is movably sleeved with a multi-headed rod 50. One side of the multi-headed rod 50 is fixedly connected with multiple groups of pistons 51. The spraying assembly includes a liquid storage chamber 52, which is opened on the upper side inside the mold 32. A diversion groove 53 is opened on one side of the bottom of the liquid storage chamber 52. Multiple groups of spray nozzles 54 are fixedly connected inside the liquid storage chamber 52. An annular moving groove 55 is opened inside the liquid storage chamber 52. The shape of the annular moving groove 55 is adapted to the swinging trajectory of the second push block 49. In this embodiment, by starting the second driving motor 34 to drive the threaded rod 35 to rotate, the threaded rod 35 rotates to drive the mold 32 to slide relative to the guide post 22 and the slide rail 31, and then the plastic preform is clamped. During the clamping process, since the air pump 39 at the bottom will continuously blow air when the material is discharged, when the mold 32 is continuously closed, the plastic preform will continuously expand. At this time, the clamping assembly will move simultaneously to clamp the top of the material. At this time, since the plastic preform will come into contact with the breakage column 28, a notch will be pierced in the plastic preform, which can well avoid the bursting of the plastic preform due to bloating during the blow molding process, reduce the internal stress, and can significantly reduce the rejection rate caused by forming defects such as uneven wall thickness, deformation, cracking, etc. At the same time, it can also reduce the forming defects caused by uneven plastic flow resistance or uneven preform expansion, thereby improving the production efficiency.

[0030] Among them, the height of the blow molding pipe 40 is higher than the height of the upper surface of the second placement groove 37. The height of the first placement groove 271 corresponds to that of the first connecting plate 27. In this embodiment, the height of the blow molding pipe 40 is higher than the height of the upper surface of the second placement groove 37, so that the blow molding pipe 40 can be better located inside the blow molding raw material when the mold 32 is closed for blow molding.

[0031] Working principle: During the working process, plastic pellet balls are poured from the feed hopper 8 into the interior of the conveying column 4. The first driving motor 5 is started to drive the spiral conveying shaft 6 to rotate. After the spiral conveying shaft 6 rotates, the plastic pellet balls are mixed and conveyed forward through the spiral. The plastic pellet balls are heated and liquefied through the pipeline of the conveying column 4. The liquefied plastic is conveyed into the interior of the material blocking column 15 through the connecting pipe 9. The liquefied plastic flows downward through the material guiding groove 17. In the discharging assembly, the material guiding column 18, the material guiding outer shell 14, and the first pushing block 13 form a storage cavity inside the material guiding outer shell 14. The liquefied plastic accumulates inside the storage bin. When the accumulated plastic reaches the quantity required for product forming, the hydraulic rod 11 is started to drive the first pushing block 13 to press downward. At this time, the first pushing block 13 presses downward to push out the material, and at the same time, the space reserved from the material blocking column 15 to the material guiding column 18 is blocked, so as to avoid the continuous output of the material, causing unnecessary waste and avoiding the increase in cost and unnecessary losses. At the same time, the first pushing block 13 presses the material downward, and the material presses the sealing block 21, causing the first spring 19 to stretch, driving the first connecting column 20 and the sealing block 21 to move downward, so that the material can be discharged through the bottom of the material guiding outer shell 14. And because the material discharges along the periphery of the sealing block 21, the material presents a hollow cylindrical state during the discharging process. At the same time, the air pump 39 is started to blow air and discharge the material at the same time during the discharging process. Since the blow molding pipe 40 is located at the center of the material, at this time, the gas circulates in the center of the material to prevent it from sticking, avoiding affecting the subsequent blow molding. At the same time, the plastic parison is immediately affected by the uniform action of the air flow while being extruded, so that the plastic can be more evenly distributed on the inner wall of the mold, which is beneficial to forming a product with uniform wall thickness; After the plastic parison reaches a certain length, the second driving motor 34 is started to drive the threaded rod 35 to rotate. The threaded rod 35 rotates to drive the mold 32 to slide relative to the guide post 22 and the slide rail 31, and then the plastic parison is clamped. During the clamping process, because the air pump 39 at the bottom continuously blows air when the material is discharged, when the mold 32 continuously closes, the plastic parison will continuously expand. At this time, the clamping assembly moves at the same time to clamp the top of the material. At this time, because the plastic parison contacts the break column 28, a notch is pierced in the plastic parison, which can well avoid the plastic parison from bursting due to gas swelling during the blow molding process, reduce the internal stress, and can significantly reduce the reject rate caused by forming defects such as uneven wall thickness, deformation, and cracking. At the same time, it can also reduce the forming defects caused by uneven plastic flow resistance or uneven parison expansion, thereby improving the production efficiency; When the mold 32 moves to completely clamp the material, the first connecting plate 27 will be inside the first placement groove 271. At this time, the first connecting plate 27 will push the top plates 42 on both sides to both sides, thereby driving the moving column 41 to move backward. The moving column 41 drives the second connecting column 46 to move backward. After the second connecting column 46 moves backward, it drives the cam 47 to rotate along the rotating shaft 48. After the rotating shaft 48 rotates, it drives the second push block 49 to move. After the second push block 49 moves, it drives the multi-head rod 50 and the piston 51 to move forward, and the demoulding agent in the guide groove 53 is pressed out through the nozzle 54. Evenly spray the release agent on the surface of the plastic parison, thereby preventing the plastic parison from sticking to the mold 32 during the blow molding process, making the demoulding process smoother and reducing the time consumed by demoulding difficulties. At the same time, evenly spraying the release agent can enable the plastic parison to be smoothly formed during the blow molding process, avoiding local thinning or tearing of the product due to local adhesion, affecting its appearance and normal use. During the demoulding process, the clamping assembly removes the molded material after the mold 32 is removed.
