Description

Technical Field

[0001] This utility model relates to a mixing device, and more particularly to a mixing machine. Background Technology

[0002] An internal mixer is a key piece of equipment used for mixing polymer materials such as rubber and plastics. Its core function is to uniformly mix raw rubber (natural or synthetic rubber) with compounding agents (such as carbon black, vulcanizing agents, fillers, etc.) through strong shearing, extrusion, and heating in a closed environment to form a compound that meets the process requirements.

[0003] However, the internal mixers have poor cleaning performance, making it difficult to clean impurities such as iron wires inside in a timely manner. At the same time, the sticky raw materials are prone to clogging at the feed inlet of the internal mixers. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide a mixer that not only has good cleaning performance, but also easily prevents related sticky raw materials from clogging at the feed inlet.

[0036] Example 1

[0037] Combination Figures 1-2 This embodiment provides a mixer, including: a machine body 1; a rotor assembly 2 rotatably located within the machine body 1; a feed hopper 3 connected to one end of the machine body 1; a plurality of cutters 4 located within the feed hopper 3; a first pipe 51 and a second pipe 52 respectively connected to the other two sides of the machine body 1; an air extractor 9, the air inlet 91 of the air extractor 9 being connected to the first pipe 51; a collection bag 6 detachably connected to the air outlet 92 of the air extractor 9; a first valve 71 located at the first pipe 51; and a second valve 72 located at the second pipe 52.

[0038] Specifically, during the internal mixing process, firstly, the first valve 71 and the second valve 72 are closed; then, raw rubber, compounding agents, and other raw materials are fed into the feed hopper 3, allowing the raw materials to enter the machine body 1. Under the action of several cutters 4, the adhering raw materials are separated, which helps to prevent the adhering raw materials from clogging the feed hopper 3; then, the feed hopper 3 is closed, and the rotor assembly 2 is started. The rotor assembly 2 performs strong shearing, extrusion, and heating on the raw materials to form a compound that meets the process requirements; finally, the second valve 72 is opened, and under the action of gravity, the compound is discharged from the second pipe body 52. ​​To improve the discharge performance, a screw feeding device can be installed in the second pipe body 52.

[0039] During cleaning, firstly, the feed hopper 3 and the first valve 71 are opened simultaneously; then, the vacuum pump 9 is turned on, so that impurities such as iron wires inside the machine body 1 enter the collection bag 6 under the dual action of gravity and pneumatic force, preventing impurities such as iron wires from directly entering the outside, thereby preventing environmental pollution and having good cleaning performance.

[0040] Furthermore, such as Figure 1 The machine body 1 includes a machine body 11 and a hopper 12 that are connected to each other. The rotor assembly 2 is rotatably located inside the machine body 11. The feed hopper 3 is connected to the machine body 11. The first pipe 51 and the second pipe 52 are respectively connected to the two sides of the hopper 12.

[0041] Specifically, the machine body 11 facilitates the rotor assembly 2 to perform strong shearing, extrusion and heating of the raw materials, and the shape of the machine body 11 is preferably cylindrical; the hopper 12 facilitates material discharge, and the shape of the hopper 12 is preferably conical. In order to facilitate support, several support legs 13 can be provided at the bottom of the hopper 12.

[0042] Furthermore, such as Figure 1 There is an opening and closing door 8 between the machine body 11 and the hopper 12.

[0043] Specifically, during internal mixing, the opening and closing door 8 is in the closed state, which facilitates the raw materials to undergo strong shearing, extrusion and heating in a relatively small enclosed space, thereby facilitating a good mixing effect of the raw materials.

[0044] Furthermore, such as Figure 1The rotor assembly 2 includes a first rotor 21 and a second rotor 22, both of which are rotatably located within the body 1. The first rotor 21 and the second rotor 22 rotate in opposite directions.

[0045] Specifically, the rotation direction is opposite, which facilitates the full shearing, extrusion and heating of the raw materials.

[0046] Furthermore, such as Figure 1 The rotor assembly 2 further includes: a driver 23 connected to the body 1, the drive shaft of the driver 23 being connected to one end of the first rotor 21; a first gear 241 connected to the other end of the first rotor 21; and a second gear 242 connected to one end of the second rotor 22, the second gear 242 meshing with the first gear 241.

[0047] Specifically, a driver 23 simultaneously drives the first rotor 21 and the second rotor 22 to rotate, which not only ensures good energy saving, but also makes the linear speeds of the first rotor 21 and the second rotor 22 the same, thereby facilitating the synchronous shearing, extrusion and heating of the raw materials. The driver 23 can be a servo motor, a stepper motor, etc.

[0048] Furthermore, such as Figure 1 The first rotor 21 and the second rotor 22 have the same structure, both including: a rotor body 251 that rotates inside the machine body 1; and a number of spiral protrusions 252 that are spaced apart and connected to the outside of the rotor body 251.

[0049] Specifically, the rotor body 251 is used to support a number of spiral protrusions 252; the spiral protrusions 252 are used to shear and compress the raw material, thereby generating heat in the raw material, while facilitating the spiral movement of the raw material and ensuring good mixing of the raw material. The specific number of spiral protrusions 252 is not limited and can be four, five, etc., and the spiral protrusions 252 are preferably evenly distributed along the circumference of the rotor body 251.

[0050] Furthermore, such as Figures 1-2 The midpoints of several cutters 4 are connected to each other to form multiple channels 41.

[0051] Specifically, multiple channels 41 facilitate the flow of raw materials cut by the cutter 4. The number of channels 41 depends on the number of cutters 4. For example, two cutters 4 will produce four channels 41, and three cutters 4 will produce six channels 41.

[0052] Furthermore, such as Figure 1 The collection bag 6 and the air outlet 92 of the vacuum pump 9 are detachably connected by a flexible wire.

[0053] Specifically, flexible wires can be made of iron wire, steel wire, etc.

[0054] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
