Description

Technical Field

[0001] The utility model relates to the field of mixing mills, in particular to a rubber turning mixing mill for mixing rubber. Background Art

[0002] The basic structure of a conventional mixing mill consists of a frame, mixing rollers, a mixing unit, and a collection unit. The collection unit includes a collection drive, a collection unit, and a collection guide. The collection guide is located vertically between the mixing rollers and the mixing unit. The collection guide is parallel to the mixing rollers, and the collection drive drives the collection unit to move back and forth along the collection guide. Rubber material discharged from the mixing rollers is directed through the collection unit to the mixing unit above the mixing rollers. The material then flows from the mixing unit to the mixing rollers for continuous mixing.

[0003] The rubber itself has a large friction coefficient, the mixing temperature of the rubber is high and the adhesion is strong. In actual production, some rubber may fall onto the rubber collecting guide rail, and the rubber collecting parts move along the rubber collecting guide rail with rubber attached. The rubber will enter between the rubber collecting guide rail and the rubber collecting parts, resulting in increased resistance to the movement of the rubber collecting parts. In severe cases, the rubber collecting parts will stop working; the moving rubber collecting parts cause the rubber to further extend on the surface of the rubber collecting guide rail, and the contaminated area of ​​the rubber collecting guide rail and the rubber collecting parts will expand, making cleaning more difficult; in addition, the basic structure of the rubber turning mill also includes an air suction hood for collecting rubber mixing waste gas. The air suction hood is fixed above the rubber turning unit and its air suction space includes the moving space of the rubber collecting parts. The air pump of the air suction hood consumes a lot of energy and has a low gas collection efficiency. Utility Model Content

[0022] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0023] like Figure 1 As shown, the rubber mixing mill for mixing rubber of this embodiment includes: a frame 1, a pair of mixing rollers 2, a rubber mixing unit 3, and a rubber collecting unit 4. The pair of mixing rollers 2 include a first clamping rod and a second clamping rod both rotating around their own axis on the frame 1. The rubber mixing unit 3 is arranged above the pair of mixing rollers 2. The rubber collecting unit 4 includes a rubber collecting driving component 401, a rubber collecting component 402 and a rubber collecting guide rail 403. The rubber collecting guide rail 403 extends along an axial direction parallel to the first clamping rod and is fixed on the frame 1. The rubber collecting driving component 401 drives the rubber collecting component 402 to reciprocate along the length direction of the rubber collecting guide rail 403, and is characterized in that the rubber collecting guide rail 403 is located above the rubber mixing unit 3.

[0024] Specifically, the rubber material discharged from the open mixing rollers 2 is introduced into the rubber turning unit 3 above the open mixing rollers 2 via the rubber collecting unit 4. The rubber material is then discharged from the rubber turning unit 3 to the open mixing rollers 2 for cyclic mixing. The rubber collecting guide 403 located above the rubber turning unit 3 prevents the rubber material from falling onto the rubber collecting guide 403 from above, thereby preventing the rubber material from entering between the rubber collecting guide 403 and the rubber collecting member 402.

[0025] In some preferred embodiments, the rubber transfer unit 3 includes a rubber transfer roller arranged parallel to the open mill roller 2, which is rotatably mounted on the frame 1. Specifically, the rubber transfer unit 3 pulls the rubber material discharged from the open mill roller 2 and then guides it into the open mill roller 2 for processing. When there is only one rubber transfer roller, the rubber transfer roller pulls the rubber material; when there are two rubber transfer rollers, both of which are designed as a pair of rollers, the rubber transfer rollers pull, squeeze, and shear the rubber material.

[0026] In the embodiment including the rubber turning roller, the function of the rubber collecting part 402 is, on the one hand, to gather and fold the rubber material discharged from the refining roller 2; on the other hand, it is to be slidably connected to the rubber collecting guide rail 403, pulling the rubber material to move back and forth axially between the refining roller 2 and the rubber turning roller, avoiding the rubber material only having partial axial contact with the refining roller 2 and the rubber turning roller, effectively reducing the local wear of the refining roller 2 and the rubber turning roller, and extending the service life of the refining roller 2 and the rubber turning roller.

[0027] like Figure 2As shown, another embodiment of the rubber mixing mill further includes an air intake hood 5, the air inlet end of which faces the rubber collecting member 402, and the air outlet end of which is connected to an air pump. Specifically, rubber mixing produces waste gas, the main pollutants of which include dust, hydrogen sulfide, carbon disulfide, toluene, and non-methane hydrocarbons.

[0028] Rubber refining waste gas will have an adverse effect on the environment and the health of production personnel; and the temperature of the rubber refining waste gas itself is relatively high, and the dust in it is easy to float up. On the one hand, it adheres to the surface of the rubber collection guide rail 403 and hinders the reciprocating movement of the rubber collection part 402 on the rubber collection guide rail 403. On the other hand, the dust adheres to the rubber material transmission path and pollutes the rubber material.

[0029] The suction hood 5 effectively collects the waste gas from rubber refining, reduces the impact of the waste gas on the environment and human health, facilitates the smooth movement of the rubber collecting member 402, and reduces the probability of dust contaminating the rubber material.

[0030] In some preferred embodiments, the suction hood 5 is located directly above the glue collecting guide rail 403. Specifically, when the suction hood 5 is located directly above the glue collecting guide rail 403, the suction hood 5 can not only remove dust adhering to the surface of the glue collecting guide rail 403 to a certain extent when it is turned on, but also effectively prevent dust from adhering to the glue collecting guide rail 403.

[0031] In some preferred embodiments, Figure 3 、 4 As shown, the glue collecting member 402 further includes a moving mechanism 4021, which is slidably connected to the glue collecting guide rail 403 and fixedly connected to the air hood 5. Specifically, the space in which the air hood 5 can effectively collect waste gas is called the air collection space. When the air hood 5 is fixedly arranged above the glue turning unit 3, in order to ensure that the glue collecting member 402 is always in the air collection space during the reciprocating movement on the glue collecting guide rail 403, the air pump energy consumption of the air hood 5 is large and the air collection efficiency is low. When the air hood 5 is fixedly connected to the moving mechanism 4021, the air hood 5 can reciprocate along the length direction of the glue collecting guide rail 403. At this time, the air hood 5 moves with the glue collecting member 402. The air pump energy consumption of the air hood is low and the air collection efficiency is high.

[0032] In some preferred embodiments, the projection of the air inlet end of the air hood 5 on the horizontal plane is the first projection, and the projection of the movable mechanism 4021 on the horizontal plane is the second projection, with the second projection being located inward of the first projection. Specifically, when the second projection is located inward of the first projection, the movable mechanism 4021 is located in the air collection space, which reduces dust accumulation on the movable mechanism and facilitates smooth movement of the movable mechanism.

[0033] In some preferred embodiments, the second projection is adjacent to the circumferential outer edge of the first projection. Specifically, the second projection is adjacent to the circumferential outer edge of the first projection, which further reduces the energy consumption of the air pump of the air hood and improves the air collection efficiency of the air hood.

[0034] In some preferred embodiments, the moving mechanism 4021 includes a sleeve that is sleeved over the adhesive collection guide rail 403. Specifically, the sliding system composed of the sleeve and the guide rail is simple in structure and easy to manufacture. However, the gap between the sleeve and the adhesive collection guide rail 403 is small, and the entry of foreign matter into the gap can easily affect the operation of the system. In addition, the friction between the sleeve and the adhesive collection guide rail 403 is sliding friction, which requires a high driving force for the adhesive collection driver 401.

[0035] In some preferred embodiments, the moving mechanism 4021 includes a pulley, which is in rolling connection with the rubber collecting guide rail 403. Figure 3 、 4 As shown, when the suction hood 5 is fixedly connected to the moving mechanism 4021, the driving force required by the glue collection driving component 401 increases. The moving mechanism 4021 is connected to the glue collection guide rail 403 through a pulley than through a sleeve, and the driving force required for the glue collection driving component 401 is smaller.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
