[0029] Further, the transmission assembly 51 comprises a transmission shaft 511, a transmission conical roller 512 and a transmission gear 513, the transmission shaft 511 is movably connected in the inside of the mixing tank 1, the transmission conical roller 512 is installed on the transmission shaft 511, and the transmission gear 513 is transmissionally connected with the driving assembly 4 and is installed on the transmission shaft 511.

[0030] The transmission shaft 511, the transmission conical roller 512 and the transmission gear 513 in the transmission assembly 51 cooperate with each other, can efficiently transmit the power of the driving motor 3 to the subsequent assembly, the design of the transmission conical roller 512 provides a basic structure for variable speed adjustment, can stably receive power and create conditions for different speed transmission, ensures the coherence and stability of power transmission, and reduces power loss.

[0031] Further, the discharging assembly 52 comprises a driving shaft 521, a driving conical roller 522, a discharging hole disc 523 and a driving gear 524, the driving shaft 521 is movably connected in the inside of the mixing tank 1, the driving conical roller 522 is installed on the driving shaft 521 and is centrally symmetrically distributed with the transmission conical roller 512, the discharging hole disc 523 is installed on the driving shaft 521 and is in communication with the raw material tank 2 and the mixing tank 1, and the driving gear 524 is installed on the driving shaft 521.

[0032] The driving shaft 521 of the discharging assembly 52 drives the driving conical roller 522, the discharging hole disc 523 and the driving gear 524 to rotate. The discharging hole disc 523 can control the falling amount and speed of the raw materials, and cooperates with the transmission assembly 51 to realize the quantitative conveying of the raw materials. The driving conical roller 522 cooperates with the transmission conical roller 512, and the discharging speed can be adjusted by changing the rotating speed, so that different raw materials can enter the mixing tank 1 according to the preset proportion, the accuracy of the raw material ratio is improved, and the structure is simple and convenient to maintain.

[0033] Further, the adjusting assembly 53 comprises an adjusting sliding table 531 and an adjusting transmission wheel 532. The adjusting sliding table 531 is installed in the mixing tank 1, and the adjusting transmission wheel 532 is arranged between the adjacent transmission conical roller 512 and the driving conical roller 522 on the adjusting sliding table 531. The adjusting transmission wheel 532 is closely combined with the adjacent transmission conical roller 512 and the driving conical roller 522 to realize transmission.

[0034] The adjusting sliding table 531 of the adjusting assembly 53 can drive the adjusting transmission wheel 532 to move, change the contact position of the adjusting transmission wheel 532 with the transmission conical roller 512 and the driving conical roller 522, and then adjust the transmission ratio of the two, so as to realize flexible adjustment of the discharging speed. This design can accurately control the conveying speed of the raw materials according to actual needs, can adapt to the change of the mixing ratio of different raw materials, and enhances the versatility and flexibility of the device.

[0035] Further, the driving assembly 4 connected with the output end of the driving motor 3 is movably connected in the mixing tank 1. The driving assembly 4 comprises a driving shaft 41, a driving gear 42 and a center gear 43. The driving shaft 41 connected with the output end of the driving motor 3 is movably connected in the mixing tank 1. The driving gear 42 meshing with the transmission gear 513 is installed on the driving shaft 41. The center gear 43 is installed on the driving shaft 41.

[0036] When the driving motor 3 starts, the output end drives the driving shaft 41 to rotate at high speed. The driving gear 42 on the driving shaft 41 is closely meshed with the transmission gear 513 in the transmission assembly 51, so that the power of the driving motor 3 is accurately transmitted to the transmission assembly 51, and the driving transmission shaft 511 and the transmission conical roller 512 are rotated to provide power source for the subsequent adjusting assembly 53 to change the transmission ratio and the discharging assembly 52 to discharge materials. At the same time, the center gear 43 on the driving shaft 41 also starts to rotate, which cooperates with the mixing gear 74 in the mixing assembly 7 to drive the revolving and rotating of the stirring auger roller 73, so that the raw materials in the mixing tank 1 are fully mixed. Through the linkage design of the driving assembly 4, the power of the two key functions of discharging and mixing is coordinated, the stable operation of the device is ensured, and the running jam or failure caused by the different power of each part is avoided.

[0037] Further, the discharge port of the raw material tank 2 is provided with an anti-blocking assembly 6, which includes a rotating sleeve 61, a rotating gear 62 and a poking rod 63. The rotating sleeve 61 is movably connected inside the discharge port of the raw material tank 2, and the outer side of the rotating sleeve 61 is provided with the rotating gear 62 which is engaged with the driving gear 524. The poking rod 63 is installed on the rotating sleeve 61 and extends into the raw material tank 2.

[0038] The anti-blocking assembly 6 ingeniously utilizes the operating power of the discharging assembly 52 to escort the discharging process of the raw material tank 2. When the driving shaft 521 rotates, the driving gear 524 rotates with it and is engaged with the rotating gear 62, thereby driving the rotating sleeve 61 to continuously rotate inside the discharge port of the raw material tank 2. The poking rod 63 on the rotating sleeve 61 penetrates into the raw material tank 2 and stirs and flips the raw materials accumulated near the discharge port. This design effectively breaks the clumps of raw materials caused by moisture, extrusion and other reasons, prevents the raw materials from accumulating and blocking at the discharge port, and ensures that the raw materials can smoothly and continuously pass through the discharge port and enter the mixing tank 1 through the discharging hole disc 523. Compared with the traditional manual periodic cleaning or the addition of independent anti-blocking driving equipment, the anti-blocking assembly 6 not only saves manpower, but also realizes efficient use of power through linkage with other parts of the device, thereby improving the operation stability and reliability of the entire device.

[0039] Further, the mixing assembly 7 includes an inner tooth ring 71, a rotating plate 72, stirring auger rollers 73 and mixing gears 74. The inner tooth ring 71 is installed inside the mixing tank 1 and located outside the driving shaft 41. The rotating plate 72 is movably connected to the inner tooth ring 71 and movably connected to the driving shaft 41. The stirring auger rollers 73 are movably connected inside the inner tooth ring 71 and extend into the mixing tank 1. The mixing gears 74 are installed on the stirring auger rollers 73 and engaged with the central gear 43 and the inner tooth ring 71.

[0040] The mixing assembly 7 adopts a unique "revolution + rotation" compound motion mode, which greatly improves the efficiency and uniformity of raw material mixing. The inner tooth ring 71 is fixed inside the mixing tank 1, providing a stable outer meshing track for the mixing gears 74. The central gear 43 rotates with the driving shaft 41 and is engaged with the mixing gears 74, causing the stirring auger rollers 73 to rotate while revolving around the driving shaft 41. During revolution, the stirring auger rollers 73 move extensively inside the mixing tank 1, fully stirring the raw materials in different areas and expanding the mixing range. When rotating, the spiral blades on the surface of the stirring auger rollers 73 generate strong pushing force, flipping the raw materials at the bottom upwards, so that the raw materials can be fully mixed in the vertical direction, achieving three-dimensional interweaving. The rotating plate 72 revolves synchronously with the stirring auger rollers 73, further enhancing the stability of the mixing process and preventing local accumulation or dead angles during stirring, ensuring that the raw materials in the mixing tank 1 are uniformly mixed to provide high-quality mixed raw materials for pipe production.

[0041] Further, the driving shaft 41 is installed with a stirring rod 8 matched with the inner wall of the mixing tank 1.

[0042] The stirring rod 8 installed on the driving shaft 41 is an important supplement to optimize the mixing effect. With the high-speed rotation of the driving shaft 41, the stirring rod 8 rotates synchronously closely with the inner wall of the mixing tank 1. While the mixing assembly 7 is mainly stirring the raw materials, the stirring rod 8 plays a wall scraping role to scrape off the raw materials attached to the inner wall of the mixing tank 1. Due to the action of gravity, centrifugal force and other factors, the raw materials are easy to adhere to the wall during the mixing process, and if not cleaned in time, it will cause the mixed raw materials to be insufficient, affecting the overall mixing quality. The continuous wall scraping action of the stirring rod 8 makes the raw materials on the wall participate in the mixing again, eliminates the mixing dead angle, further improves the uniformity of the raw materials mixing, and ensures that all raw materials in the mixing tank 1 can be fully and uniformly stirred, providing higher quality and uniform mixing raw materials for pipe production, and improving the quality stability of pipe products.

[0043] Further, the mixing tank 1 is installed with a visual sensor 10 acting on the driving gear 524.

[0044] The visual sensor 10 on the mixing tank 1 acts on the driving gear 524, which can monitor the rotating speed of the driving gear 524 in real time, and through the rotating speed, the conveying speed and quantity of the raw materials can be deduced, so that the operator or the control system can master the raw material adding situation in real time, and if there is deviation, it can be adjusted in time, realizing the intelligent monitoring of raw material mixing and improving the controllability of the mixing process.

[0045] Further, the diameter of the discharge port of the raw material tank 2 is larger than the hole opened on the discharging hole disc 523.

[0046] The diameter of the discharge port of the raw material tank 2 is larger than the hole on the discharging hole disc 523, which can ensure sufficient supply of raw materials at the discharge port, avoid insufficient supply of raw materials due to too small discharge port, and at the same time, the small hole of the discharging hole disc 523 can accurately control the falling speed and quantity of the raw materials, and the cooperation of the two can not only ensure sufficient supply of raw materials, but also realize accurate discharging, improving the stability and accuracy of raw material conveying.

[0047] In the application, the power of feeding and mixing is realized by the driving assembly 4, the monitoring feedback system of the identification ribbon and the visual sensor 10 is combined by the variable speed assembly 5, the leakage prevention design of the sealing ring 9 is matched, the accurate feeding of the raw materials according to the preset proportion is realized, the multiple raw materials are added according to the proportion for multiple times in small amounts, so that the mixing pressure is reduced; the mixing assembly 7 adopts the "revolution + rotation" compound motion mode, and the stirring rod 8 is scraped to remove the raw materials on the tank wall, so that the mixing efficiency and uniformity are greatly improved; the anti-blocking assembly 6 avoids the clogging of the raw materials by the power of the discharging assembly 52, without additional driving equipment, the overall operation is stable and reliable, the automation degree is high, and the demand of the raw material mixing operation of the large-scale pipe material can be met; the application has the advantages of accurate and controllable raw material proportioning, sufficient and uniform mixing, smooth feeding process, efficient structure linkage and reliable operation specification, etc., the transmission ratio is changed by adjusting the position of the transmission wheel, and the visual sensor 10 is combined to realize real-time monitoring and correction, so that the accurate regulation and control of the raw material proportion are realized; only one driving motor 3 is used to drive multiple components to operate, the use of independent power source is reduced, the energy consumption is reduced, and the system coordination is improved; the specification inspection in the early stage reduces the operation error and fault risk from the source, and the whole is suitable for the scene with high requirement for raw material mixing precision.

[0048] The use method of the device is:

[0049] Step one: check the sealing and cleanliness of each raw material tank 2 to ensure that there is no residual impurity; according to the raw material proportion required by the pipe production, the corresponding raw material is added into the raw material tank 2 arranged in a ring array, and attention should be paid to avoid that the raw material exceeds the maximum capacity of the raw material tank 2 to prevent overflow during feeding,

[0050] Step two: check whether the discharge port of the mixing tank 1 is closed, whether each connecting component such as the connection between the driving motor 3 and the driving shaft 41 and the fit state of the transmission assembly 51 and the discharging assembly 52 is firm, confirm that the adjustment transmission wheel 532 in the adjustment assembly 53 has been adjusted to closely fit with the adjacent transmission conical roller 512 and the driven conical roller 522 through the adjustment sliding table 531, ensure the stable transmission, and check whether the visual sensor 10 is aligned with the driven gear 524 to ensure the normal identification function;

[0051] Step three: according to the raw material proportioning requirement, the position of the adjustment transmission wheel 532 is adjusted by the adjustment sliding table 531, because the adjustment transmission wheel 532 and the transmission conical roller 512 and the driven conical roller 522 are different in fit position, the transmission ratio is changed, and then the rotating speed of the driven shaft 521 is adjusted, the discharging hole disc 523 rotates with the driven shaft 521, and the speed difference will cause the amount of raw materials entering the mixing tank 1 through the discharging hole disc 523 in unit time to be different, so that the accurate regulation and control of the raw material proportion are realized,

[0052] Step four: turn on the power, start the drive motor 3, the output end of the drive motor 3 drives the driving shaft 41 to rotate, the driving gear 42 on the driving shaft 41 meshes with the transmission gear 513, drives the transmission shaft 511 and the transmission conical roller 512 to rotate, and through the transmission effect of adjusting the transmission wheel 532, the shaft 521 and the blanking hole disc 523 are synchronously rotated, and the feeding to the mixing tank 1 is started according to the set proportion;

[0053] Step five: when the blanking hole disc 523 rotates, the hole periodically connects the discharge port of the raw material tank 2 and the inside of the mixing tank 1, the raw material enters the mixing tank 1 under the action of gravity, the visual sensor 10 identifies the driving gear 524, and the rotating speed and the feeding amount of the blanking hole disc 523 are monitored in real time, so that the position of the adjusting transmission wheel 532 is adjusted through the adjusting slide 531, the rotating speed and the feeding amount of the blanking hole disc 523 are adjusted in real time, and the feeding accuracy is ensured;

[0054] Step six: when the driving shaft 521 rotates, the driving gear 524 meshes with the rotating gear 62, the rotating sleeve 61 and the poking rod 63 rotate in the raw material tank 2, the poking rod 63 stirs the raw material in the raw material tank 2, avoids the raw material from caking and blocking the discharge port, and ensures that the feeding process is smooth;

[0055] Step seven: when the driving shaft 41 rotates, the central gear 43 rotates synchronously, meshes with the mixing gear 74, and at the same time, the mixing gear 74 meshes with the inner tooth ring 71, drives the stirring auger roller 73 to rotate while revolving around the driving shaft 41, and the rotating plate 72 rotates synchronously with the revolving of the stirring auger roller 73, so that the mixing stability is enhanced;

[0056] Step eight: the rotation of the stirring auger roller 73 generates a spiral pushing force to turn the raw material at the bottom upwards, the revolution expands the stirring range, so that different raw materials are fully interwoven in the mixing tank 1, at the same time, the stirring rod 8 on the driving shaft 41 rotates and adheres to the inner wall of the mixing tank 1, so that the raw material adhering to the inner wall is scraped off, the mixing is avoided, and the mixing effect is further improved;

[0057] Step nine: when the material in the raw material tank 2 is discharged, the drive motor 3 is turned off, and the feeding and mixing process is stopped, so that the material in the mixing tank 1 can be taken out.

[0058] The above is only a preferred embodiment of the present application, and does not limit the present application in any form, so any modification, equivalent change and modification of the above embodiment according to the technical essence of the present application, which does not deviate from the technical solution content of the present application, still belongs to the scope of the technical solution of the present application.
