In addition, the multi-station design allows multiple raw materials to be mixed at the same time. Each mixing bin can work independently, but can work together as a whole. This parallel operation mode not only effectively shortens the production cycle, but also increases the flexibility of the production line.

[0044] The precise design of the feed assembly is also one of the keys to improving efficiency. Through the smooth movement of the push mechanism, the feed guide ramp can accurately align with the feed port of each mixing bin, ensuring that the raw materials can enter each mixing bin efficiently and accurately. This design reduces the steps of manual operation, improves the level of automation, reduces the waste and loss of raw materials during operation, and further improves the continuity and stability of the entire production process.

[0045] In summary, the multi-station synchronous mixing operation of the device shows obvious advantages in terms of equipment structure design, ease of operation and production efficiency. It realizes an efficient PVC particle production process by combining advanced technologies such as multi-station mixing, synchronous stirring, and flip mixing. The implementation of this device not only improves the uniformity of mixing and production efficiency, but also simplifies the production operation process and reduces the maintenance cost of the equipment. By improving the automation level of the production line, the device provides more reliable and efficient technical support for the production and preparation of PVC particles for cable sheath production, showing good application prospects.

In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the invention.

[0061] It should be noted that if the embodiments of the invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0062] In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the invention.

[0063] See also Figure 1-7, a PVC granule production and preparation device for cable sheath production, including a base 1, the main function of the base is to carry the entire device and provide stable support. Side brackets 2 are respectively provided on the left and right sides of the top of the base 1, which are used to support and fix the multi-station mixing component 3 above. The mixing component 3 is a key component for mixing raw materials to prepare PVC granules. It is installed between the top ends of the side brackets 2 on both sides and can be flipped by a flipping drive mechanism 4, thereby improving the uniformity of the mixing.

[0064] The specific structure of the multi-station mixing assembly 3 includes: a mixing box 31 that can be turned over, and the turning of the mixing box is driven by a turning drive mechanism 4 installed on the right side bracket 2. Three mixing bins 32 are distributed on the left and right sides of the center of the mixing box 31, and each mixing bin is used to mix different raw materials respectively. A top cover 34 is installed on the top of the mixing box 31, and the top cover is raised and lowered by a telescopic cylinder 33 installed inside, thereby controlling the opening and closing of the mixing box.

[0065] When mixing materials, six stirring shafts 35 are installed on the left and right sides of the center of the bottom of the top cover 34. These stirring shafts are respectively located directly above the mixing bin 32 and are used to stir the raw materials. The rotation of the stirring shaft is realized by a synchronous drive mechanism 36, which includes a first drive motor 362 installed on the top of the top cover 34. The motor drives a plurality of driven gears 356 to rotate through a driving gear 363 and a plurality of transmission gears 364, and then drives each stirring shaft 35 to rotate synchronously through six driving shafts 366, thereby realizing multi-station synchronous mixing.

[0066] The feed assembly 5 is used to transport raw materials into the mixing box 31. The feed assembly includes a slide 51 installed on the top of the base 1, and a feed guide ramp 53 is connected to the top of the slide through a support 52. Six guide chutes 54 are provided on the top of the ramp, corresponding to the six mixing bins 32 in the mixing box 31. The raw materials are transported to the guide chutes by six elevators 56 on the top of the ramp, and then slid to the front lead-out convex plate 55 through the chutes, and then correspondingly guided to the inside of each mixing bin 32. A discharge valve pipe 37 is provided at the bottom of each mixing bin 32 to discharge the mixed materials.

[0067] The pushing mechanism 6 is used to realize the translational movement of the feeding assembly 5 on the base. The pushing mechanism includes a second driving motor 61 installed in the longitudinal mounting groove 11 at the top of the base 1. The motor drives the screw rod sleeve 63 to move by driving the screw rod 62, thereby pushing the feeding assembly 5 to move forward and backward along the guide rail 12. Through such a design, the six lead-out convex plates 55 in the feeding assembly 5 can be accurately aligned with the feeding ends of the six mixing bins 32, ensuring that the raw materials can be efficiently and accurately delivered into the mixing bin.

[0068] To ensure the stability of the movement of the feed assembly 5, guide rails 12 are provided on both sides of the longitudinal mounting groove 11 at the top of the base 1, and a slider 13 is slidably connected in the guide rail. The slider is connected to the bottom of the feed assembly 5 to ensure that the feed assembly can slide smoothly along the guide rail under the action of the driving motor without deviation or jamming.

[0069] How it works

[0070] Start the pushing mechanism 6: the second driving motor 61 works, and drives the screw rod 62 to drive the screw rod sleeve 63 to move, thereby pushing the feeding assembly 5 to move forward along the guide rail 12.

[0071] Feeding: The raw materials are transported by the elevator 56 to the guide chute 54 on the top of the feed guide ramp 53, and are slid through the chute to the front lead-out convex plate 55, and then are correspondingly guided to each mixing bin 32 in the mixing box 31.

[0072] Mixing: After the raw materials enter the mixing bin 32, the telescopic cylinder 33 drives the top cover 34 to descend and close the mixing box 31. The first drive motor 362 drives the stirring shaft 35 to rotate synchronously through the driving gear 363, the transmission gear 364 and the driven gear 356, and the driving shaft 366 to mix the raw materials. At the same time, the turning drive mechanism 4 drives the mixing box 31 to turn over to improve the uniformity of the mixing.

[0073] Discharging: After the mixing is completed, the discharging valve pipe 37 at the bottom of the mixing bin 32 is opened to discharge the mixed materials.
