Description

Technical Field

[0001] This utility model relates to the technical field of plastic production equipment, specifically to a raw material heating and melting device for plastic production that prevents clogging. Background Technology

[0002] Plastics are polymers made from monomers through addition or condensation polymerization. Generally, plastics have a low density; for example, the density of polyethylene is usually between 0.91 and 0.97 g / cm³. This makes products made from plastics easy to handle and transport.

[0003] However, in plastic production, traditional heating and melting devices are prone to blockage of pipes or heating chambers due to moisture and clumping of raw materials, which cannot ensure smooth heating and melting of plastic raw materials. Secondly, traditional stirring devices cannot continuously agitate the plastic raw materials during use, which not only causes uneven heating of the raw materials, but also leads to problems such as easy accumulation. Utility Model Content

[0013] This invention features a raw material feeding assembly with vibrating motors on both sides of the conical barrel. These motors periodically vibrate the conical barrel, preventing the raw material from accumulating and clumping inside. Additionally, dryers on both sides of the barrel remove moisture from the plastic raw material, preventing clumping caused by moisture. This structure perfectly solves the problem of heating barrel blockage caused by clumping of plastic raw material due to moisture, thus ensuring smooth heating and melting of the plastic raw material.

[0014] This invention features a heating and melting assembly in which a reciprocating telescopic cylinder works in conjunction with an annular guide rail, and an annular rack meshes with gears on several rotating shafts. This allows the shafts to rotate a certain distance and then rotate in the opposite direction, thereby continuously agitating the plastic material during the heating and melting process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-7As shown, the present invention proposes a plastic production raw material heating and melting device for preventing blockage. It includes a base 1, a heating and melting component 2 on one side of the base 1, and a raw material feeding component 4 on the other side of the base 1. The heating and melting component 2 and the raw material feeding component 4 are connected by a uniform conveying component 3. A controller 5 is provided on the base 1 between the heating and melting component 2 and the raw material feeding component 4.

[0027] The heating and melting assembly 2 includes a heating barrel 21 fixedly connected to the base 1. The heating barrel 21 is made of stainless steel, which has good high temperature resistance and corrosion resistance. Insulation material is wrapped around the outside of the heating barrel 21 to reduce heat loss. The top of the heating barrel 21 is provided with a first mounting seat 22 and a second mounting seat 23, which are interconnected. An annular guide rail 24 is slidably connected inside the first mounting seat 22, and an annular rack 25 is fixedly connected to the annular guide rail 24. Several rotating shafts 26 are mounted on the first mounting seat 22 and the heating barrel 21, and gears 27 are installed on the shafts 26 within the first mounting seat 22. These gears 27 interact with the annular rack 25. The strips 25 mesh with each other, and a stirring plate 28 is provided on several rotating shafts 26 inside the heating barrel 21. A reciprocating telescopic cylinder 29 is hinged to one side wall of the second mounting base 23. The output end of the reciprocating telescopic cylinder 29 is hinged to the annular guide rail 24. A power supply 210 is provided on the top of the heating barrel 21 on one side of the first mounting base 22. An electric heating tube 211 is provided on the inner side wall of the heating barrel 21. The electric heating tube 211 can raise the temperature inside the heating barrel 21 to carry out the melting operation. A discharge pipe 212 is also provided at the bottom of the heating barrel 21. A control valve 213 is provided on the discharge pipe 212. When the melted plastic raw material can flow out from the discharge pipe 212, the control valve 213 can control the flow rate.

[0028] The raw material feeding assembly 4 includes two support rods 41 fixedly connected to the base 1. The two support rods 41 are fixedly connected to a feeding barrel 42. The bottom of the feeding barrel 42 is connected to a conical barrel 43. The bottom of the conical barrel 43 is connected to a passage barrel 44. The top of the feeding barrel 42 is hinged to a cover plate 48.

[0029] Two vibration motors 45 are fixedly connected to the two support rods 41. The two vibration motors 45 are correspondingly set with the conical barrel 43 and can vibrate periodically to prevent the plastic raw material from accumulating and clumping in the feed barrel 42.

[0030] Support plates 46 are provided on the two support rods 41 below the vibration motor 45. Dryers 47 are provided on the two support plates 46. The output ends of the two dryers 47 are corresponding to the through barrel 44. The operation of the dryers 47 can remove moisture from the plastic raw materials, thereby avoiding the problem of clumping caused by moisture.

[0031] The uniform conveying component 3 includes two connecting rods 31 fixedly connected to the base 1. The two connecting rods 31 are connected to a conveying pipe 32. A drive motor 34 is fixed to one side of the conveying pipe 32 by a fastener 33. The transmission end of the drive motor 34 passes through the side wall of the conveying pipe 32 and is provided with a spiral blade 35, which can make the plastic raw material uniformly conveyed into the heating tank 21. The conveying pipe 32 is provided with a groove 36, which is correspondingly set with the passage tank 44. The end of the conveying pipe 32 away from the drive motor 34 is connected to the heating tank 21.

[0032] A temperature sensor 214 is also provided on the inner wall of the heating tank 21. The temperature sensor 214 is connected to the controller 5. The temperature sensor 214 monitors the temperature inside the heating tank 21 and transmits the signal to the controller 5.

[0033] The principle and usage process of this utility model:

[0034] Before use, the staff first connects all electrical components to the power supply. When it is needed, the staff first opens the cover plate 48 on the top of the feeding barrel 42, and then pours the plastic raw material into the feeding barrel 42. The plastic raw material first passes through the conical barrel 43, and then through the passing barrel 44. Since the vibration motors 45 on both sides of the conical barrel 43 are working, they can vibrate regularly to prevent the raw material from accumulating and clumping in the feeding barrel 42. Then the dryers 47 on both sides of the passing barrel 44 work to remove the moisture in the plastic raw material and avoid the problem of clumping caused by moisture. Then, the plastic raw material falls from the bottom of the passing barrel 44 into the conveying pipe 32. The drive motor 34 drives the transmission end to rotate and drives the spiral blades 35 to rotate. Therefore, the plastic raw material can be evenly conveyed into the heating barrel 21. Then the plastic raw material falling into the heating barrel 21 begins to undergo melting.

[0035] Power supply 210 supplies power to electric heating tube 211, which is responsible for heating the plastic material in heating tank 21 to a molten state. During the heating process, reciprocating telescopic cylinder 29 continuously rotates the annular guide rail 24 on mounting base 22. The reciprocating annular guide rail 24 drives the annular rack 25 to rotate, further causing several gears 27 to rotate. Therefore, the stirring plate 28 on the rotating shaft 26 located in heating tank 21 continuously turns the plastic material back and forth, making the material heated evenly and accelerating the melting process. At the same time, the temperature sensor 214 on the inner wall of heating tank 21 can monitor the stability inside heating tank 21 in real time and transmit the signal to controller 5. The molten plastic material can flow out from discharge pipe 212, and the control valve 213 on discharge pipe 212 can accurately control the flow rate.
