The equipment accelerates the melting of the material on the lower heating plate by extrusion between the two heating plates through the melting device and through the sieve hole. However, the conveying device and the melting device are separately arranged, so that the particles need to be melted first, and then conveyed to the extrusion head for extrusion through the conveying device, which greatly reduces the forming efficiency.

[0004] In view of the above problems, the present application provides a plastic pipe high-efficiency forming equipment integrated with an intelligent feeding system to solve the above problems. SUMMARY

[0009] Preferably, the feeding assembly includes: a feeding column fixed below the extrusion chamber and communicating with the conveying chamber; a separating screen fixed above the feeding column; a follower shaft rotatably disposed near the lower end of the feeding column, and a bevel gear set installed at its position inside the feeding column, one end of the follower shaft extending into a connecting chamber and connecting with a synchronous gear; a conveying column fixed inside the feeding column, and a protective chamber fixed to its lower end face by multiple connecting rods, the protective chamber wrapping around the outside of the bevel gear set; and a one-way disc slidably disposed inside the feeding column, and a pressing spring disposed between the disc and the conveying column.

[0013] Compared with the prior art, the present invention provides a high-efficiency plastic pipe forming device with an integrated intelligent feeding system, which has the following beneficial effects:

[0014] This invention utilizes multiple heating devices to heat the extrusion assembly in distinct zones, with the heating intensity gradually increasing to enhance the heating of the plastic. This enables intelligent temperature control, preventing large plastic particles from being insufficiently heated and failing to reach the molten state. Once the plastic reaches the molten state, it can be separated by a separation component, allowing the molten plastic to enter the separation component and preventing overheating and carbonization. During separation, the feeding component controls the falling rate of the plastic, preventing molten plastic from remaining in the extrusion chamber for further heating. Furthermore, the separation component, through the cooperation of the discharge component and the spiral blades, enables precise and intelligent feeding, avoiding interruptions in the feeding process.

[0021] Reference Figures 1-5 This invention provides a technical solution: a high-efficiency plastic pipe forming device with an integrated intelligent feeding system, comprising: a drive base 1 on which an extrusion motor 2 is fixed; a base 3 fixed to one side of the drive base 1, and an extrusion assembly 4 fixed to its upper end face; a feed hopper 5 on the extrusion assembly 4; multiple heating devices 6, equidistantly mounted on the extrusion assembly 4; multiple heat preservation devices 7, equidistantly mounted on the extrusion assembly 4 and located away from the feed hopper 5; an extrusion head 8 fixed to the output end of the extrusion assembly 4; and a separation assembly 9 fixed below the extrusion assembly 4.

[0022] It should be noted that multiple heating devices 6 can heat the extrusion component 4 in different areas, and the degree of heating is gradually increased to improve the heating of the plastic, realize intelligent temperature control, and avoid large plastic particles not being heated enough to enter the melting state.

[0023] In this embodiment, the extrusion assembly 4 includes: an extrusion chamber 41 fixed on the base 3; an extrusion shaft 42 rotatably disposed inside the extrusion chamber 41 and driven by the extrusion motor 2, wherein the diameter of the extrusion shaft 42 gradually increases from the feed hopper 5 toward the extrusion head 8; and a spiral blade 43 fixed on the outer wall of the extrusion shaft 42.

[0024] It should be noted that the diameter of the extrusion shaft 42 is consistent with that of the corresponding position of the heat preservation device 7. The distance between it and the extrusion chamber 41 only allows molten plastic to pass through, avoiding the entry of granular plastic, which would affect the extrusion effect. The extrusion chamber 41 is divided into a heating section and a heat preservation section through the heating device 6 and the heat preservation device 7. The diameter of the extrusion shaft 42 gradually increases from the feed hopper 5 to the extrusion head 8, which allows the gradually melting plastic particles to come close to the inner wall of the extrusion chamber 41, thereby improving the heating effect.

[0025] In a preferred embodiment, the separation assembly 9 includes: a plurality of feeding assemblies 91, which are equidistantly fixed below the extrusion chamber 41 and staggered with a plurality of heating devices 6; a discharging assembly 92, which is fixed below the extrusion chamber 41 and located between the heating devices 6 and the heat preservation devices 7; a conveying chamber 93, which is fixed below the feeding assembly 91 and the discharging assembly 92; a drive chamber 94, which is fixed at one end of the conveying chamber 93 near the discharging assembly 92; a connecting chamber 95, which is fixed at one end of the conveying chamber 93 away from the discharging assembly 92; and a spiral conveying blade 96, which is rotatably disposed within the conveying chamber 93.

[0026] It should be noted that the outer wall of the conveying chamber 93 is equipped with a heat preservation device 7 to prevent the plastic inside the conveying chamber 93 from solidifying and to enhance its flow effect; that is, when the plastic is heated to a molten state, it can enter the conveying chamber 93 through the feeding component 91, thereby avoiding overheating.

[0027] In a preferred embodiment, the two ends of the spiral conveying blade 96 extend into the drive chamber 94 and the connecting chamber 95 respectively, and are driven by a motor in the drive chamber 94. A synchronous gear is fixed at one end of the spiral conveying blade 96 located in the connecting chamber 95. A shaft 961 is fixed at one end of the spiral conveying blade 96 near the drive chamber 94. Two actuating blades 962 are fixed on the outer circumference of the shaft 961, and the position of the shaft 961 corresponds to the discharge assembly 92.

[0028] When the molten plastic is conveyed to the shaft 961, the two actuating blades 962 can convey the plastic upward, so that it is close to the discharge assembly 92, which facilitates the discharge operation of the discharge assembly 92.

[0029] In a preferred embodiment, the feeding assembly 91 includes: a feeding column 911, fixed below the extrusion chamber 41 and communicating the extrusion chamber 41 with the conveying chamber 93; a separating screen, fixed above the feeding column 911; a follower shaft 912, rotatably disposed near the lower end of the feeding column 911, with a bevel gear set 913 installed inside the feeding column 911, one end of the follower shaft 912 extending into the connecting chamber 95 and connecting to a synchronous gear; a conveying column 915, fixed inside the feeding column 911, with a protective chamber 914 fixed to its lower end face by multiple connecting rods 916, the protective chamber 914 wrapping around the outside of the bevel gear set 913; and a one-way disc 917, slidably disposed inside the feeding column 911, with a pressing spring between it and the conveying column 915.

[0030] In a preferred embodiment, a reinforcing member 918 is fixed near the upper end of the feed column 911, and a feed shaft 919 is rotatably arranged between the reinforcing member 918 and the protective chamber 914. A conveying blade is fixed at the corresponding position of the feed shaft 919 and the conveying column 915, and the one-way disk 917 is slidably connected to the feed shaft 919.

[0031] In other words, when the plastic is heated to a molten state, before it is conveyed to the heat preservation section of the extrusion chamber 41, the molten plastic enters the feed column 911 through the separation net, thereby pressing the one-way disc 917 and causing the plastic to flow into the conveying column 915. The conveying blades on the feed shaft 919 accelerate the conveying of the plastic, allowing the plastic to quickly enter the conveying chamber 93, thus avoiding excessive molten plastic remaining in the heating section of the extrusion chamber 41.

[0032] In a preferred embodiment, the discharge assembly 92 includes: a discharge column 921, fixed below the extrusion chamber 41 and communicating the extrusion chamber 41 with the conveying chamber 93; a lower sliding plate 922, slidably disposed within the discharge column 921 at its lower end; an upper sliding plate 923, slidably disposed within the discharge column 921 at its upper end; a sliding shaft 924, fixed between the lower sliding plate 922 and the upper sliding plate 923, with a reciprocating groove 925 formed in its middle; a rotating shaft 926, rotatably disposed within the discharge column 921 and driven by a motor within the drive chamber 94; and an eccentric plate 927, fixed on the rotating shaft 926 and corresponding to the reciprocating groove 925.

[0033] In a preferred embodiment, both the lower sliding disk 922 and the upper sliding disk 923 are provided with a plurality of discharge holes 928, and a plurality of blocking disks 929 are hinged to the lower sliding disk 922, with each of the plurality of blocking disks 929 corresponding to one of the plurality of discharge holes 928.

[0034] In other words, when the discharge assembly 92 discharges material, the rotation of the rotating shaft 926 drives the eccentric disk 927 to rotate, which in turn pushes the sliding shaft 924 to slide back and forth through the reciprocating groove 925. This causes the lower sliding disk 922 to intermittently contact the shaft 961, thus discharging the plastic. When the lower sliding disk 922 slides down, the plastic pushes the blocking disk 929 to rotate, allowing the plastic to enter the discharge column 921. When the lower sliding disk 922 slides up, it pushes the plastic in the discharge column 921 upwards and flows out from the discharge hole 928 of the upper sliding disk 923 into the insulation section. It should be noted that when the agitator blade 962 on the shaft 961 rotates once, the lower sliding disk 922 reciprocates four times, meaning that material is fed twice between the two agitator blades 962 to avoid collisions with the agitator blades 962.

[0035] Specifically, firstly, multiple heating devices 6 can heat the extrusion assembly 4 in different areas, with the heating degree gradually increasing to improve the heating degree of the plastic and achieve intelligent temperature control. This avoids the large plastic particles not being heated enough to enter the molten state. After the plastic enters the molten state, it can be separated by the separation assembly 9, so that the molten plastic enters the separation assembly 9, avoiding carbonization caused by excessive heating. During separation, the feeding assembly 91 can control the falling rate of the plastic, thereby preventing the molten plastic from remaining in the extrusion chamber 41 for further heating. Furthermore, the separation assembly 9, through the cooperation of the discharge assembly 92 and the spiral blade 43, can perform precise and intelligent feeding, avoiding feeding interruptions.

[0036] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
