Technical Field

[0001] The utility model relates to the technical field of masterbatch production, in particular to a forming device for spherical masterbatch. Background Art

[0002] The forming technology of spherical masterbatch is an important processing method in modern industrial production, and is widely used in many fields such as chemical industry, pharmaceutical industry, food industry, etc. The core of this technology lies in making raw materials into spherical particles with excellent fluidity and uniformity through specific technological processes to meet the needs of subsequent processing or direct use. Usually, the forming process of spherical masterbatch begins with the selection and pretreatment of raw materials, and then forms a preliminary particle structure through methods such as extrusion and spheronization.

[0003] The extrusion method usually heats the raw materials to a plastic state and extrudes them through a mold with a specific shape, and then obtains approximately spherical particles through cutting and spheronization; while the spheronization method is to add a liquid binder to a rotating container to make the powder raw materials gradually aggregate and roll into balls.

[0004] In the above methods, the roundness, density, etc. of the formed products are prone to fluctuations, resulting in a decline in product quality. Summary of the Utility Model

Detailed implementation mode

[0024] The technical solutions in the present utility model will be further described below in conjunction with the drawings and embodiments.

[0025] As Figure 1-2 shown, the forming device for spherical masterbatch includes an upper forming roller 100 and a lower forming roller 200 that are meshed. The upper forming roller 100 and the lower forming roller 200 are both evenly distributed with corresponding spherical recesses 110. A convex edge 111 is integrally formed at the edge of the spherical recess 110, and the convex edges 111 of the corresponding spherical recesses 110 are in contact with each other. The convex edge 111 is used to ensure that the material in the spherical recess 110 can be cut from the outer waste material.

[0026] As Figure 1 、 3 shown, a conveying table 300 is provided on one side of the lower forming roller 200. The conveying table 300 includes a support frame 310 and a driving roller 320 and a driven roller 330 respectively arranged on both sides of the support frame 310. A row of guide plates 311 are evenly distributed along the width direction of the support frame 310, and the guide plates 311 are located between the driving roller 320 and the driven roller 330. A conveyor belt 340 is provided between the driving roller 320 and the driven roller 330. A plurality of conveyor belts 340 are provided, and the conveyor belts 340 are arranged between the guide plates 311. Each conveyor belt 340 corresponds to a group of corresponding spherical recesses 110. Since the strip-shaped material coming out of the extrusion head is relatively soft, the conveyor belts 340 need to convey synchronously to avoid deformation.

[0027] As Figure 1 、 4As shown in the figure, a cooling water tank 400 is provided on the other side of the lower forming roller 200. A vertically arranged partition net 410 is provided in the middle of the cooling water tank 400. The partition net 410 divides the cooling water tank 400 into a cooling area 420 and a separation area 430. The cooling area 420 is close to the lower forming roller 200. Specifically, a water inlet 421 is provided in the cooling area 420. An outlet 431 is provided in the separation area 430. A water pump 440 is connected between the outlet 431 and the water inlet 421 to realize the flow of water in the cooling water tank 400, allowing the water to flow from the cooling area 420 to the separation area 430, and enabling one of the spherical masterbatch and the waste to follow the water flow through the partition net 410.

[0028] Specifically, whether it is the spherical masterbatch or the waste in the separation area 430 needs to be selected according to the volume and shape of the waste. For example, if the strip-shaped material entering the upper forming roller 100 and the lower forming roller 200 is thick, strip-shaped waste will be formed. Therefore, the partition net 410 needs to be selected with mesh holes slightly larger than the spherical masterbatch. If the strip-shaped material entering the upper forming roller 100 and the lower forming roller 200 is thin, waste similar to a triangle will be formed. Therefore, it is appropriate to select mesh holes slightly smaller than the spherical masterbatch, or special-shaped mesh holes, to block the spherical masterbatch from entering.

[0029] As Figure 4 shown in the figure, the top position of the partition net 410 inclines towards the separation area 430, and an L-shaped drain net 411 is provided at the top of the separation area 430. With this structure, the water flow will gradually push the spherical masterbatch or waste in the cooling area 420 onto the L-shaped drain net 411 to drain.

[0030] As Figure 1 shown in the figure, a cooling box 500 is provided at one end of the transfer table 300 away from the lower forming roller 200. A drip tube 510 is provided on the upper side of the cooling box 500. A suction pump 520 is communicated between the drip tube 510 and the cooling box 500 for the preliminary cooling of the strip-shaped material. At the same time, cooling liquid will remain on the surface of the strip-shaped material, avoiding the formed spherical masterbatch from getting stuck in the spherical recess 110 when passing between the upper forming roller 100 and the lower forming roller 200.

[0031] As Figure 5 shown in the figure, fans 210 are provided at both ends of the upper forming roller 100 and the lower forming roller 200 to cool the upper forming roller 100 and the lower forming roller 200 and prevent their temperatures from being too high.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
