Description

Technical Field

[0001] The utility model relates to the technical field of plastic masterbatch, in particular to a uniformly heated kneading machine used for producing plastic masterbatch. Background Art

[0002] Masterbatch is composed of three basic elements: pigment or dye, carrier, and additives. It is an aggregate made by uniformly loading an extraordinary amount of pigment into a resin. Kneaders are used in the production and processing of masterbatches. Kneaders are ideal equipment for kneading, mixing, vulcanizing, and polymerizing high-viscosity, elastic-plastic materials.

[0003] Currently, when mixing masterbatch raw materials, a kneading machine chassis uses two Σ-shaped stirring rods to stir the masterbatch raw materials. However, this processing method has the following shortcomings: most kneading machine chassis are one-piece barrel structures, which makes it very easy for the masterbatch raw materials to remain on the inner wall of the kneading machine chassis after processing. The one-piece structure of the kneading machine chassis makes it difficult to discharge the residual masterbatch raw materials, and the residual masterbatch raw materials will clump, thereby affecting the service life of the kneading machine chassis; the Σ-shaped stirring rods make it difficult to stir the masterbatch raw materials at the bottom of the kneading machine chassis, which makes it difficult to stir all the masterbatch raw materials deposited on the masterbatch raw materials, thereby affecting the efficiency of masterbatch raw material production. Utility Model Content

[0004] The purpose of the utility model is to solve the problem of inconvenience in cleaning the kneading machine box in the prior art, and to propose a kneading machine for producing plastic masterbatch with uniform heating.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-Figure 3 A uniformly heated kneading machine for the production of plastic masterbatches includes a bracket 1 and a barrel 3 for mixing the masterbatches, and a sealing cover 13 is connected to the opening of the barrel 3 by bolts. The oil heating in the oil storage chamber 20 can heat the masterbatch raw materials. This technical solution is a prior art and will not be elaborated on here.

[0021] The bracket 1 is rotatably mounted with a driven rod 2 connected to the barrel 3. The barrel 3 is provided with a circumferentially distributed oil storage cavity 20 for heating the masterbatch. The bracket 1 is connected to a moving rod 11 through a moving member, and a driven rod 12 connected to a sealing cover 13 is rotatably mounted on the moving rod 11. Figure 1 As shown, one side of the barrel body 3 is opened and closed by the sealing cover 13, and the barrel body 3 can be opened by moving the sealing cover 13, thereby making it more convenient for the operator to clean the inside of the barrel body 3.

[0022] The moving part includes a motor 2 8 fixedly mounted on the bracket 1, and a screw rod 9 is fixedly connected to the output end of the motor 2 8. A matching nut 10 is provided on the sliding sleeve of the screw rod 9. A moving rod 11 is provided on the nut 10. The screw rod 9 is arranged horizontally. A guide block is fixedly mounted on the nut 10. A guide rod matching the guide block is fixedly mounted on the bracket 1. A driven rod 2 12 is arranged horizontally. The guide rod guides the guide block, thereby limiting the moving direction of the nut 10. The nut 10 can drive the moving rod 11, the driven rod 2 12, and the sealing cover 13 to move synchronously through the drive of the motor 2 8.

[0023] A rotating assembly for driving the barrel body 3 to rotate is installed on the bracket 1.

[0024] The rotating assembly includes a rack 4 fixedly mounted on the barrel body 3, a motor 5 fixedly mounted on the bracket 1, and the output end of the motor 5 is fixedly connected to a rotating shaft 6 which is transmission-connected to the rack 4, the rotating shaft 6 is horizontally arranged above the barrel body 3, and a gear 7 meshing with the rack 4 is fixedly mounted on the rotating shaft 6. When the motor 5 is energized, the barrel body 3 is rotated as a whole, and the barrel body 3 can fully mix the masterbatch raw materials when rotating. When the barrel body 3 rotates, the masterbatch raw materials can be fully dispersed to avoid precipitation of the masterbatch raw materials.

[0025] A stirring assembly for stirring the masterbatch is installed in the barrel 3.

[0026] The stirring assembly includes a motor 3 14 fixedly installed in the barrel body 3, and the output end of the motor 3 14 is fixedly connected to an active rod 15 extending into the barrel body 3, and a support rod 16 and a stirring rod 19 for stirring the masterbatch are fixedly installed on the active rod 15, and a mixing rod 17 for stirring the masterbatch is fixedly installed on the support rod 16, and the mixing rod 17 is provided with a scraper 18 that movably contacts the inner wall of the barrel body 3.

[0027] After the motor 3 14 is energized, the stirring rod 19 can stir the masterbatch raw materials in the barrel body 3. When the mixing rod 17 rotates, it not only stirs the masterbatch raw materials, but also drives the scraper 18 to scrape the inner wall of the barrel body 3, thereby removing the masterbatch raw materials accumulated on the inner wall of the barrel body 3, so that the masterbatch raw materials will not stick to the inner wall of the barrel body 3 to form agglomerates, thereby effectively improving the service life of the barrel body 3.

[0028] It should be noted that the specific models and specifications of motor 1 5 , motor 2 8 , and motor 3 14 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0029] The functional principle of this utility model can be explained through the following operation modes:

[0030] Put the masterbatch to be processed into the barrel 3;

[0031] The output end of the motor 1 5 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the gear 7 to pull the meshing rack 4. When the rack 4 rotates, it drives the driven rod 1 2 to rotate through the barrel 3. When the barrel 3 rotates, it drives the sealing cover 13 and the driven rod 2 12 to rotate, thereby causing the barrel 3 to drive the masterbatch to stir;

[0032] The motor 3 14 drives the active rod 15 to rotate, and the active rod 15 drives the support rod 16, the stirring rod 19, the mixing rod 17, and the scraper 18 to rotate. The stirring rod 19 and the mixing rod 17 can fully stir the masterbatch, and the scraper 18 can scrape the masterbatch attached to the inner wall of the barrel 3;

[0033] When the masterbatch is mixed, it is conducive to the next processing of the masterbatch;

[0034] When the inner wall of the barrel 3 needs to be cleaned, the bolts are removed;

[0035] The output end of motor 2 8 drives the screw rod 9 to rotate. When the screw rod 9 rotates, it drives the nut 10 to move horizontally. When the nut 10 moves, it drives the moving rod 11, the driven rod 2 12, and the sealing cover 13 to move synchronously. The sealing cover 13 is disconnected from the opening of the barrel body 3, and the operator can clean the inside of the barrel body 3.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
