Description

Technical Field

[0001] This invention relates to the field of color mixing machine technology, specifically a self-priming color mixing machine for PC material processing. Background Technology

[0002] A color mixing machine utilizes the high-speed rotation of vortex-shaped material-feeding blades to cause plastic granules or resin powder to tumble, collide, rub, and generate heat. This allows the material to be mixed with color while simultaneously causing moisture to evaporate rapidly from the exhaust pipe, achieving a drying effect. It is widely used in the production of plastic products and is classified into vertical color mixing machines, horizontal color mixing machines, drum-type color mixing machines, and drying color mixing machines.

[0003] Mixing machines are generally used to mix materials of granular size. However, existing color mixing machines usually pour the materials directly into them during feeding. Since the materials are generally stored and transported in special bags, which are relatively large, feeding requires a great deal of manual labor or a self-priming structure to pour the materials into the device. This makes feeding the device extremely difficult. Furthermore, the self-priming feeding structure has drawbacks, as it can easily cause the material to fail to be drawn into the device during the initial suction. Summary of the Invention

[0004] This invention provides a self-priming color mixing machine for PC material processing, which has the beneficial effect of convenient suction. It solves the problem mentioned in the background art that the mixing machines generally mix materials of particle size. When feeding the existing color mixing machines, the materials are usually poured directly into them. The materials are generally stored and transported in special bags, which are large in volume. When feeding, a lot of manual labor or a self-priming structure is required to pour the materials into the device, making the feeding of the device extremely difficult.

[0015] The present invention has the following beneficial effects:

[0016] 1. This self-priming color mixing machine for PC material processing provides a connecting support effect for the first and second connecting ends through an outer adhesive layer. While connecting the first and second connecting ends, the outer adhesive layer also provides a rotational support effect for the first and second connecting shafts. This gives the feeding structure a transmission effect and a bending function during rotation, allowing the first and second connecting shafts to output power even at bending angles. In conjunction with the feeding pipe, the feeding pipe can bend at multiple angles when conveying materials, and the feeding pipe also has the function of flexibly adjusting direction and height during transmission.

[0017] 2. This self-priming color mixing machine for PC material processing, through the action of the connecting rod, provides an inward contraction and pulling force to the first and second connecting ends. This, combined with the sleeve rod and support rod, forms a supporting force, providing support for the connecting support structure while also enabling bending motion. This further strengthens the connection between the two parts, increases the torque transmission strength of the connecting support structure, and allows for stable conveying of heavy materials. Through the cooperation of the feeding structure and feeding pipe, the machine provides a self-contained material conveying function, changing the conventional and cumbersome feeding method, reducing the labor intensity of workers, and further strengthening the toughness and strength of the conveying pipe, ensuring it can support the conveying of multiple materials and can convey large quantities of material at once.

[0018] 3. This self-priming color mixing machine for PC material processing, through the cooperation of the external hexagonal rotating pin sleeve and the shrinking threaded shaft, and by varying the distance the shrinking threaded shaft extends into the shrinking sleeve, can change or adjust the tensile force of the connecting rubber rods. This mechanism provides adjustment for the tightness of each connecting rubber rod. By adjusting the connecting rubber rods at designated positions, the force on each connecting rubber rod is made the same, and the degree of bending between the first and second connecting ends is changed, ensuring that the first and second connecting ends remain in the same axial position. This facilitates the overall torque output of the feeding structure. The cooperation between the connecting bearing and the support bearing provides movable support for the inner shaft frame and the outer rubber layer, thus enabling the connection structure between the first and second connecting ends to rotate. This gives the device an anti-lock function when the feeding structure is inside the feeding tube, preventing the first and second connecting shafts from locking up during rotation and causing damage to the internal structure.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please see Figure 1-8 One type of self-priming color mixing machine for PC material processing includes a support base 1 and an inner cylinder 2 on the support base 1. A cover 13 is installed on the upper end of the inner cylinder 2, and a stirring motor 10 is installed on the upper end of the cover 13. An operation panel 14 is installed on the outer side of the inner cylinder 2. A receiving box 15 is installed on the upper end of the cover 13. A feeding motor 16 is provided on one side of the receiving box 15. A feeding pipe 17 is installed on one end of the receiving box 15. A feeding structure 4 is installed inside the feeding pipe 17. The feeding structure 4 includes a first connecting shaft 40, a second connecting shaft 41, and a threaded ring leaf 42. The second connecting shaft 41 is installed on one end of the first connecting shaft 40. Threaded ring leaves 42 are installed on the outer sides of both the first connecting shaft 40 and the second connecting shaft 41. One end of the first connecting shaft 40 is connected to one end of the second connecting shaft 41. A spiral keel 46 is installed on the inner wall of the feeding pipe 17, and a wear-resistant inner layer 47 is installed on the inner wall of the feeding pipe 17.

[0031] Mixing machines are generally used to mix materials of particle size. However, existing color mixing machines usually pour materials directly into them during feeding. Since materials are generally stored and transported in special bags, which are large in volume, a great deal of manual labor is required to pour the materials into the device during feeding, making the feeding process extremely difficult.

[0032] One end of the feeding pipe 17 is placed into a special bag. The feeding motor 16 rotates, driving the feeding structure 4 inside the feeding pipe 17. When the first connecting shaft 40 rotates, it drives the threaded annular leaf 42 to rotate around the outside of the first connecting shaft 40. Through its spiral motion, the material inside the bag moves within the feeding pipe 17. The conveyed material is pushed along the fixed inner wall of the feeding pipe 17 for transport. The threaded annular leaf 42 transports it to the receiving box 15, where it falls into the inner cylinder 2. The inner wall of the feeding pipe 17 is equipped with a spiral keel 46 and a wear-resistant inner layer 47. To avoid prolonged friction between the threaded annular blade 42 and the inner wall of the feeding pipe 17, thus reducing its lifespan, and to increase the overall toughness of the feeding pipe 17, the feeding structure 4 and the feeding pipe 17 are designed to work together to provide the device with a self-contained material conveying function. This changes the conventional and cumbersome feeding method, reduces the labor intensity of workers, and further enhances the toughness and strength of the conveying pipe, ensuring that it can support the conveying of multiple materials and can convey a large amount of material at once.

[0033] Example 2

[0034] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1-8 A connecting support structure 6 is installed at one end of the first connecting shaft 40. The connecting support structure 6 is used to connect the second connecting shaft 41 to the threaded ring leaf 42. The connecting support structure 6 includes a first connecting end 61, a second connecting end 62 and an outer adhesive layer 63. The second connecting end 62 is installed at one end of the first connecting end 61, and the outer adhesive layer 63 is installed on one side of the first connecting end 61. The outer adhesive layer 63 is used to connect the first connecting end 61 and the second connecting end 62.

[0035] The feeding tube 17 is made of flexible material, while the first connecting shaft 40 and the second connecting shaft 41 are rigidly connected, making it difficult to bend. This also causes the first connecting shaft 40 to only operate in a vertical or parallel state when feeding, which greatly reduces the flexibility of the feeding tube 17 when feeding.

[0036] The outer rubber layer 63 is made of rubber and provides a connection and support effect for the first connecting end 61 and the second connecting end 62. While connecting the first connecting end 61 and the second connecting end 62, the outer rubber layer 63 can also provide a rotational support effect for the first connecting shaft 40 and the second connecting shaft 41. This gives the feeding structure 4 a transmission effect during rotation and a bending function during rotation. It also allows the first connecting shaft 40 and the second connecting shaft 41 to output power even at bending angles. In conjunction with the feeding pipe 17, the feeding pipe 17 can bend at multiple angles when conveying materials, and it also has the function of flexibly adjusting direction and height while conveying materials.

[0037] Example 3

[0038] This embodiment is an improvement upon embodiment 2. For details, please refer to [link / reference]. Figure 1-8 Both ends of the first connecting shaft 40 and the second connecting shaft 41 are provided with connecting holes 43. The outer side of the connecting holes 43 is provided with a vertical groove 44 located on the outer side of the first connecting shaft 40 and the second connecting shaft 41. A curved groove bracket 45 is installed at one end of the vertical groove 44. One end of the first connecting end 61 and the second connecting end 62 is provided with a mating and fixing structure 9. The mating and fixing structure 9 includes a snap-fit ​​end 91 and a positioning pin 92. The outer side of the snap-fit ​​end 91 is provided with a positioning pin 92, which is used to snap into the vertical groove 44.

[0039] The connecting support structure 6 is a support structure for the second connecting shaft 41 and the first connecting shaft 40, but its installation with both is not convenient and not stable enough, which greatly affects the use.

[0040] Insert one end of the snap-fit ​​end 91 into the interior of the connecting hole 43, while the positioning pin 92 snaps into the interior of the vertical groove 44. At this time, the connecting hole 43 is located between the vertical groove 44 and the curved groove frame 45. Then rotate the snap-fit ​​end 91 in the corresponding direction so that the positioning pin 92 snaps into the interior of the curved groove frame 45, forming a support state and completing the fixation state between the two. This makes the installation between the first connecting shaft 40, the second connecting shaft 41 and the connecting support structure 6 faster and easier, and makes the device more stable.

[0041] Example 4

[0042] This embodiment is an improvement upon embodiment 3. For details, please refer to [link / reference]. Figure 1-8 One end of the snap-fit ​​end 91 is provided with a shrinkable inner cavity 93, and a support spring 94 is installed inside the shrinkable inner cavity 93. A push plate 95 is installed on one side of the support spring 94.

[0043] When the positioning pin 92 is stuck inside the curved slot frame 45, the lack of a limiting structure makes it difficult to fix it inside the curved slot frame 45. During use, the positioning pin 92 is likely to come out of the curved slot frame 45, which will cause the feeding structure 4 to break.

[0044] The push plate 95 provides outward pushing power support, and then the push plate 95 abuts against the inside of the connecting hole 43, providing opposite thrust between the snap-fit ​​end 91 and the connecting hole 43. At this time, the positioning pin 92 is positioned inside the curved slot frame 45. Through the thrust generated by the snap-fit ​​end 91 and the shrinking inner cavity 93, the positioning pin 92 is completely snapped inside the curved slot frame 45, and a limiting force is provided for it, so as to prevent the positioning pin 92 from disengaging when it is inside the curved slot frame 45, thereby strengthening the fixed support force between the first connecting shaft 40 and the connecting support structure 6.

[0045] Example 5

[0046] This embodiment is an improvement upon embodiment 4. For details, please refer to [link / reference]. Figure 1-8 Both the second connecting end 62 and the first connecting end 61 are equipped with a supporting inner shaft frame 64 on one side. A connecting rubber rod 65 is installed at one end of the supporting inner shaft frame 64. The connecting rubber rod 65 is used to connect the two supporting inner shaft frames 64. A mating sleeve rod 39 is provided at the middle position of one end of the supporting inner shaft frame 64. A supporting top rod 37 is installed at one end of the mating sleeve rod 39. A connecting ball pin 38 is installed at one end of the supporting top rod 37. The connecting ball pin 38 is used to be installed inside the mating sleeve rod 39.

[0047] The outer adhesive layer 63 provides significant support when transporting small materials, but it is insufficient in terms of connection strength when supporting larger or heavier materials. This makes it difficult to withstand the torque during transport and may also lead to some potential problems.

[0048] Through the action of the connecting rod 65 and the cooperation between the two, the connecting rod 65 provides an inward contraction and pulling force to the first connecting end 61 and the second connecting end 62. Together with the sleeve rod 39 and the support rod 37, it forms a supporting force, providing support for the connecting support structure 6 while also enabling bending motion. This further strengthens the connection between the two parts of the device, while also enabling bending and increasing the torque transmission strength that the connecting support structure 6 can support, allowing the device to stably transport heavy materials.

[0049] Example 6

[0050] This embodiment is an improvement upon embodiment 5. For details, please refer to [link / reference]. Figure 1-8The connecting rod 65 has a partition inside. One end of the partition has a shrink sleeve 66 located outside the connecting rod 65, and the other end of the partition has a shrink threaded shaft 67 located outside the connecting rod 65. The shrink threaded shaft 67 is used to insert into the shrink sleeve 66. One end of the shrink sleeve 66 has an external hexagonal pin sleeve 68 on its outer side. The inner wall of the external hexagonal pin sleeve 68 is threadedly connected to the shrink threaded shaft 67.

[0051] Multiple connecting rods 65 are arranged on one side of the inner support frame 64, providing an inward contraction force for the two inner support frames 64. At the same time, the inner support frame 64 transmits the force to the first connecting end 61 and the second connecting end 62. However, if the force intensity is different, the multiple connecting rods 65 contract with each other, which will cause the first connecting end 61 and the second connecting end 62 to be skewed, affecting the use of the device.

[0052] The inner wall of the external hexagonal swivel sleeve 68 is connected to the outer side of the shrink threaded shaft 67 by threaded engagement. By rotating the external hexagonal swivel sleeve 68, the shrink threaded shaft 67 will shrink into the shrink sleeve 66. The shrinkage of the shrink threaded shaft 67 into the shrink sleeve 66 will increase the tensile strength of the current supporting inner shaft frame 64. Through the cooperation between the external hexagonal swivel sleeve 68 and the shrink threaded shaft 67, and by the length of the shrink threaded shaft 67 extending into the shrink sleeve 66, the tensile force of the connecting rubber rod 65 can be changed or adjusted. Through this mechanism, the tightness adjustment function of each connecting rubber rod 65 can be provided. By adjusting the connecting rubber rod 65 at a specified position, the force of each connecting rubber rod 65 can be made to be the same, and the degree of bending between the first connecting end 61 and the second connecting end 62 can be changed, so that the first connecting end 61 and the second connecting end 62 always remain in the same axial position.

[0053] Example 7

[0054] This embodiment is an improvement upon embodiment 6. For details, please refer to [link / reference]. Figure 1-8 A friction wheel 31 is provided on the outer side of the inner shaft support 64. A threaded pin 34 is installed on the inner side of the first connecting end 61. A limit spring 35 is installed at the lower end of the threaded pin 34. An arc-shaped clamping plate 32 is installed at the lower end of the limit spring 35. A short toothed pin 33 is provided on the outer side of the friction wheel 31. A support bearing 36 is installed on the outer side of the other end of the inner shaft support 64. The support bearing 36 is used to rotate the inner shaft support 64 inside the first connecting end 61. A connecting bearing 18 is installed in the middle position inside the outer rubber layer 63.

[0055] If a single-section feeding structure 4 inside the feeding pipe 17 becomes stuck while the device is transporting materials, the entire feeding structure 4 will become fixed, and the driving components will also be damaged.

[0056] The outer side of the threaded pin 34 is threadedly engaged with the inner side of the first connecting end 61. Through the cooperation of the threaded pin 34 and the limiting spring 35, a downward pressing force is provided on the arc-shaped clamping plate 32. The outer side of the friction wheel 31 is provided with a limiting tooth groove, which makes the arc-shaped clamping plate 32 press against the outer side of the short toothed pin 33. The inner wall of the arc-shaped clamping plate 32 is provided with a tapered toothed pin, which is completely fitted with the outer side of the friction wheel 31 to form an interlocking structure, so that the first connecting end 61 is in a linked state with the inner support frame 64 when it rotates.

[0057] When the feeding structure 4 gets stuck, if the force of the stuck force is greater than the tightness of the fit between the arc-shaped clamping plate 32 and the short toothed pin 33, the conical toothed pin on the inner side of the arc-shaped clamping plate 32 will disengage from the outer side of the short toothed pin 33, making the first connecting end 61 and the inner support shaft frame 64 movable. When the first connecting end 61 rotates, the connecting bearing 18 and the support bearing 36 cooperate to provide movable support for the inner support shaft frame 64 and the outer rubber layer 63, thereby enabling the connection structure between the first connecting end 61 and the second connecting end 62 to have a rotation function. This gives the device an anti-lock function when the feeding structure 4 is inside the feeding tube 17, preventing the feeding structure 4 from locking up and causing damage to the internal structure.

[0058] Example 8

[0059] This embodiment is an improvement upon embodiment 7. For details, please refer to [link / reference]. Figure 1-8 The lower end of the upper cover 13 is equipped with a drive shaft 11. The inner cylinder 2 is provided with a placement groove 12. The placement groove 12 is equipped with a stirring structure 7. The stirring structure 7 includes an inner shell 71, a support shaft 72, a stirring shaft 73, and a support rod frame 74. The support shaft 72 is installed inside the inner shell 71. The stirring shaft 73 is installed at the lower end of the support shaft 72. The support rod frame 74 is installed on the outer side of the support shaft 72. The support rod frame 74 is used to install the support shaft 72 inside the inner shell 71. A connecting gear 75 is installed at the upper end of the support rod frame 74. A gear support frame 76 is installed at the upper end of the support rod frame 74. A symmetrical gear frame 77 is installed on one side of the gear support frame 76. An inner wall scraper 78 is provided at one end of the stirring shaft 73. A stirring plate 79 is provided on one side of the inner wall scraper 78.

[0060] After the material is mixed inside the inner cylinder 2, it needs to be removed, but the existing structure makes it difficult to remove it quickly;

[0061] The lower end of the drive shaft 11 is equipped with a drive gear. After the inner housing 71 is inserted into the placement groove 12, the connecting gear 75 and the placement groove 12 are coaxial. At the same time, the symmetrical gear frame 77 and the drive gear are in a toothed meshing state. As the placement groove 12 rotates, it drives the symmetrical gear frame 77 to rotate, and then the symmetrical gear frame 77 drives the connecting gear 75 to rotate. The rotation of the connecting gear 75 provides rotational driving force for the stirring shaft 73. The outer side of the stirring plate 79 has the same curvature as the inner wall of the storage cylinder 82. While the rod 73 rotates, the inner wall scraper 78 and the agitating plate 79 can push away the material adhering to the inner wall of the storage cylinder 82, preventing the material from accumulating at the edge of the storage cylinder 82. Through the action of the agitating structure 7, the device can remove the agitating structure and the material together, which is convenient for material collection and allows for a direct view of the condition of the internal agitating structure, facilitating the maintenance of the agitating structure. Furthermore, when the inner housing 71 is inserted into the placement slot 12, it will not affect the driving status of the power structure, making the operation flexible and reducing the time wasted during material collection.

[0062] Example 9

[0063] This embodiment is an improvement upon embodiment 8. For details, please refer to [link / reference]. Figure 1-8 The inner wall of the inner housing 71 is provided with a limiting inner cavity 80. A paddle 81 is installed inside one side of the inner housing 71. A storage cylinder 82 is installed inside the limiting inner cavity 80. A positioning pin 83 is provided on one side of the storage cylinder 82. The upper end of the paddle 81 is used to abut against the lower end of the positioning pin 83.

[0064] When the inner shell 71 is removed, the material is mixed with the inner shell 71, making removal difficult. If the stirring structure 7 is flipped over to remove the material, the operation is inconvenient.

[0065] Pressing the lower end of the lever 81 causes the upper end of the lever 81 to be pushed outward through the lever principle, disengaging it from the lower end of the positioning pin 83 and removing the storage cylinder 82 from the inside of the limiting cavity 80. Through the cooperation of the stirring structure 7 and the lever 81, the device can remove the material as a whole without affecting the stirring power output of the device. Furthermore, the lever 81 enables the material inside to be removed as a whole, allowing the stirring structure to separate from the material on its own, facilitating the storage of the material. This device can remove the material inside the device as a whole, greatly improving the material collection efficiency of the device.

[0066] Example 10

[0067] This embodiment is an improvement upon embodiment 9. For details, please refer to [link / reference]. Figure 1-8One end of the feeding pipe 17 is equipped with a material extraction structure 5. The material extraction structure 5 includes a support plate 51, a connecting vertical rod 52, an outer ring frame 53, and an extended feeding end 54. One end of the support plate 51 is provided with a connecting vertical rod 52, one end of the connecting vertical rod 52 is equipped with an outer ring frame 53, and the other end of the support plate 51 is provided with an extended feeding end 54.

[0068] When the feeding pipe 17 is conveying materials, one end needs to be placed inside the bag containing the materials. However, due to the structure of the feeding structure 4, the material collection efficiency is low when materials are placed inside for retrieval, making it difficult to achieve the function of rapid material collection. The extended feeding end 54 is vertically inserted into the bag containing materials. The operator holds the connecting vertical rod 52 or the outer ring frame 53 by hand to adjust the state of the material extraction structure 5. Through the extension structure of the extended feeding end 54, the contact range between the threaded ring leaf 42 and the material is wider, allowing more material to be quickly rolled into the threaded ring leaf 42, thereby further increasing the material collection of the feeding pipe 17.
