Description

Technical Field

[0001] This utility model relates to the field of metering and mixing equipment technology, and in particular to a precise metering and mixing device for multi-component raw materials used in the production of color masterbatch. Background Technology

[0002] In the production of color masterbatches, the precise metering and uniform mixing of raw materials are the core factors determining product quality. As a key additive for coloring polymer materials, color masterbatches typically contain multiple components such as carrier resin, pigments, dispersants, and stabilizers. The precision of the proportions of each component directly affects the coloring power, dispersibility, and color stability of the subsequent products.

[0003] In existing metering and mixing devices, to prevent the weighed masterbatch from spilling out of the mixing container during feeding, the discharge pipe of the weighing container is often inserted inside the mixing container. Consequently, a cap to seal the discharge port of the discharge pipe is also installed inside the mixing container. This requires reaching into the relatively confined and shielded space inside the mixing container to open and close the cap, making the operation cumbersome and inconvenient. Furthermore, to accommodate manual access to open and close the cap, additional holes need to be made in the top cover plate of the mixing container for hand access, which affects the container's effectiveness in shielding and preventing leakage of the masterbatch. Utility Model Content

[0004] In view of this, the present invention provides a multi-component raw material precision metering and mixing device for color masterbatch production, so as to solve the problem that it is cumbersome and inconvenient to operate the cap by having to put one's hand into the shielded and relatively confined space inside the mixing container.

[0005] The technical solution proposed by this utility model is as follows: a multi-component raw material precise metering and mixing device for color masterbatch production, specifically including a mixing silo, a star-shaped retainer welded to the top opening of the mixing silo, and a weighing tank fixedly installed above the star-shaped retainer; a feeding pipe welded to the bottom of the weighing tank, the star-shaped retainer being composed of a horizontal retaining rod and a collar welded together, the feeding pipe and the collar being assembled through; a synchronous transmission ring slidably mounted on the weighing tank, a U-shaped drive ring slidably mounted on the top of the star-shaped retainer, and two connecting rods symmetrically rotating between the U-shaped drive ring and the synchronous transmission ring; two L-shaped sliding shafts symmetrically welded to the bottom of the synchronous transmission ring, a conical plug welded between the tail ends of the two L-shaped sliding shafts, the conical plug covering the bottom opening of the feeding pipe when sliding upward, the L-shaped sliding shafts slidingly engaging with the horizontal retaining rod; a Z-shaped threaded rocker rotatably mounted on the top of the horizontal retaining rod, the tail end of the Z-shaped threaded rocker rotatably connected to the U-shaped drive ring.

[0006] Furthermore, four load-bearing lugs are symmetrically welded to the bottom side of the outer periphery of the weighing tank, and a weighing sensor is fixedly connected between the load-bearing lugs and the horizontal retaining rod.

[0007] Furthermore, a threaded lug is welded to the top of the tail end of one of the horizontal retaining rods, and the Z-shaped threaded rocker arm and the threaded lug are screwed together through the thread.

[0008] Furthermore, four T-shaped grooves are symmetrically provided on the four horizontal retaining rods, and the long side rod of the U-shaped drive ring has a T-shaped cross-section structure, which slides through the T-shaped groove.

[0009] Furthermore, two track rings are fixedly connected to the top part of the inner circumference of the mixing silo, which are spaced apart vertically. An annular track groove is formed between the two track rings. A toothed ring is rotatably installed in the annular track groove. Multiple L-shaped stirring rods are welded around the inner circumference of the toothed ring. The L-shaped stirring rods are located inside the mixing silo.

[0010] Furthermore, an arc-shaped through groove is provided on the peripheral wall of the mixing silo corresponding to the position of the annular track groove. An L-shaped wheel axle is welded to the outer periphery of the mixing silo near the arc-shaped through groove. A relay gear is rotatably mounted on the L-shaped wheel axle. The relay gear passes through the arc-shaped through groove and meshes with the gear ring for transmission.

[0011] Furthermore, a drive assembly is fixedly installed on the outer periphery of the mixing silo below the arc-shaped through groove. A drive gear is fixedly mounted on the power output shaft of the drive assembly, and the drive gear meshes with the relay gear for transmission.

[0012] This utility model provides a precise metering and mixing device for multi-component raw materials in masterbatch production, which has the following beneficial effects: I. In this utility model, the cone-shaped plug inside the mixing silo can be opened and closed simply by rotating the Z-shaped threaded rocker in both directions in the external space above the mixing silo. Compared with the prior art, this eliminates the trouble of having to put one's hand into the relatively confined space inside the mixing silo to open and close the plug. The operation is simpler, and it also eliminates the need to make additional holes in the fan-shaped cover plate for the hand to enter the mixing silo in order to accommodate the operation of manually reaching into the mixing silo to open and close the plug. This prevents the additional holes from affecting the shielding and leakage prevention effect of the mixing silo and the fan-shaped cover plate on the masterbatch.

[0013] Second, the four symmetrically distributed load cells can disperse and evenly measure the mass of the material put into the weighing tank. Compared with the traditional design of only setting a single load cell at the center of the bottom of the weighing tank for centralized weighing, this avoids the situation where the weight of the material cannot be stably concentrated on the central axis of the weighing tank, which would prevent the single load cell in the center from accurately weighing the material. This helps to improve the accuracy of weighing the material. Attached Figure Description

[0023] Implementation 2: This embodiment is based on Implementation 1, but with the following additions: Two track rings 107 are fixedly connected to the top part of the inner circumference of the mixing silo 1, which are distributed vertically and horizontally. An annular track groove is formed between the two track rings 107. A toothed ring 7 is rotatably installed in the annular track groove. Multiple L-shaped stirring rods 701 are welded around the inner circumference of the toothed ring 7. The L-shaped stirring rods 701 are located inside the mixing silo 1. Preferably, there are three L-shaped stirring rods 701.

[0024] Preferably, an arc-shaped through groove 108 is provided on the periphery of the mixing silo 1 at the position corresponding to the annular track groove.

An LED digital display screen is embedded in the front side wall of the electrical control box 5, and the weighing control module is communicatively connected to the LED digital display screen.

[0029] This embodiment includes.

[0030] The working principle, specific details, implementation steps, functions and interrelationships of the features in the above embodiments, and the roles these features play in realizing this technical solution will be described and explained in detail below: In use, the bagged masterbatch is lifted and hoisted to the top of the weighing tank 2. Then, the bottom discharge port of the bag is opened, and the masterbatch is poured into the weighing tank 2. Four weighing sensors 6 can detect and weigh the masterbatch in the weighing tank 2 in real time. The four symmetrically arranged weighing sensors 6 can weigh the weight distributed on the four symmetrical load-bearing lugs 201 of the weighing tank 2. The weight data measured by the four weighing sensors 6 are transmitted to the weighing control module in real time. The weighing control module sums and calculates the actual total mass of the material inside the weighing tank 2. The weighing control module transmits the calculated actual total mass data to the LED digital display screen for real-time viewing by on-site personnel. When the weight of the masterbatch reaches the specified weight, feeding stops, and the cone-shaped opening mechanism slides down. The conical plug 8 is used to unload the masterbatch material into the mixing silo 1 through the open feed pipe 202, where it awaits mixing. This completes the weighing and feeding of the first type of masterbatch material. The feeding of the second type of masterbatch material then begins. Before the second feeding operation, the conical plug 8 is slid up and covered onto the bottom feed port of the feed pipe 202. The above operation process is repeated. This process can achieve the weighing and feeding of multiple components of masterbatch material in the specified proportion. After all components of masterbatch material have been fed according to the specified weight, the drive assembly 9 is started. Through the meshing transmission of the drive gear 901 and the relay gear 102, the drive assembly 9 can mesh with the drive gear ring 7 and the three L-shaped stirring rods 701 to rotate around the annular track groove, thereby mixing the multiple components of masterbatch material that are waiting to be mixed in the mixing silo 1.

[0031] Four symmetrically distributed weighing sensors 6 can disperse and uniformly measure the mass of the material put into the weighing tank 2. Compared with the traditional design of setting only one weighing sensor 6 at the bottom center of the weighing tank 2 to perform centralized weighing measurement of the material, this can avoid the fact that the weight of the material cannot be stably concentrated on the central axis of the weighing tank 2, which would prevent the single weighing sensor 6 in the center from performing accurate weighing detection of the material. This helps to improve the accuracy of weighing measurement of the material.

[0032] The U-shaped drive ring 4, two connecting rods 301, and synchronous transmission ring 3 together form a double-crank slider mechanism. Through this mechanism, when the forward and reverse rotation of the Z-shaped threaded rocker 106 propels the U-shaped drive ring 4 toward or away from the weighing tank 2, it drives the synchronous transmission ring 3, two L-shaped sliding shafts 302, and the conical plug 8 to slide up and down. This controls the conical plug 8 to block or separate from the bottom discharge port of the discharge pipe 202, thus opening and closing the discharge pipe 202. Therefore, in this invention, only the forward and reverse rotation of the Z-shaped threaded rocker 106 in the external space above the mixing silo 1 is needed. A single operation can achieve the sliding opening and closing of the conical cover 8 concealed in the mixing silo 1. Compared with the prior art, this eliminates the trouble of having to put one's hand into the relatively confined space inside the mixing silo 1 to open and close the cover, which is similar to the conical cover 8. The operation is simpler. It also eliminates the need to make additional holes on the fan-shaped cover plate 105 for the hand to enter the mixing silo 1 in order to accommodate the operation of manually reaching into the mixing silo 1 to open and close the cover. This prevents the additional holes from affecting the shielding and leakage prevention effect of the mixing silo 1 and the fan-shaped cover plate 105 on the masterbatch.

[0033] It is worth noting that the composition of the control unit and the weighing control module, the selection of the models of the weighing sensor 6 and the LED digital display screen, the connection and wiring method between the control unit and the drive assembly 9, the connection and wiring method between the weighing control module and the weighing sensor 6, and the control principle of the control unit on the drive assembly 9 are all existing technologies for those skilled in the art who are engaged in the design, upgrading and testing of equipment electrification, and therefore will not be elaborated here.

[0034] The following points should be noted in this article: 1. The accompanying drawings of this utility model embodiment only involve the structures involved in this utility model embodiment; other structures can refer to general designs.

[0035] 2. Where there is no conflict, the embodiments of this utility model and the features in the embodiments can be combined with each other to obtain new embodiments.
