Description

Technical Field

[0001] The present application relates to the technical field of rubber production, and in particular to a calendering device and a calendering method for a rubber film. Background Art

[0002] The inner layer rubber calendering equipment in rubber tire production is one of the key production equipment, which is used to calender the rubber material into a rubber film of the required shape and thickness for use in the subsequent tire manufacturing process.

[0003] In the manufacture of the inner layer film of the rubber tire, it is necessary to use a calender to squeeze out the bubbles in the kneaded rubber material to prevent the bubbles from affecting the subsequent manufacture and use of the rubber tire, and finally form a rubber film of the required shape and thickness for the subsequent manufacture of rubber tires.

[0004] Although the existing rubber film calendering device can meet the basic needs of rubber calendering processing, when squeezing out the bubbles in the rubber material, the calendering effect that the rubber can perform when passing through a set of rotating rollers is limited. Therefore, it is often necessary to manually place the rubber material inside the calender for extrusion processing repeatedly. After multiple extrusions and exhaust, a rubber film of the desired shape and thickness is finally formed. Therefore, this method has the problem of low processing efficiency.

[0005] In addition, since the temperature of the rubber material after mixing is often high, it is easy to stick to the roller during the calendering process. Therefore, when the rubber is calendered, it is necessary to clean the rubber adhering to the roller, which is not only very troublesome, but also affects the overall efficiency of the rubber calendering process, so it cannot fully meet people's usage needs.

[0006] For example, a patent document with a publication number of CN214725841U discloses a new calendering device for a rubber pad production process. In the technical solution described in the patent document, the rubber material is rolled by a rotating roller structure. When the rubber material passes through the roller structure, the rotating roller structure can only perform roller exhaust treatment on the corresponding areas of the rubber material in sequence. Therefore, the rubber material needs to be rolled for multiple times to meet the need for sufficient exhaust. Moreover, because the roller structure only meets the basic requirement of rolling the rubber material, it cannot cool the rubber material while rolling it. The temperature of the rubber material is often high, and its high temperature will cause it to have a strong viscosity. Therefore, it will also cause the rubber material to easily adhere to the rolling structure. It is time-consuming and laborious to clean the rubber material adhering to the rolling structure, so it cannot fully meet people's use needs. Summary of the invention

Through the cooperation of the fixed plug rod 67, the fixed plug hole 68 and the connecting spring 69, the third scraper plate 66 can slide and buffer relative to the mounting plate 15, thereby preventing the third scraper plate 66 from colliding with the vibrating pressure roller 6, thereby preventing the third scraper plate 66 and the vibrating pressure roller 6 from being damaged due to friction and collision.

[0075] Reference Fig.10 , the elastic telescopic connection module includes a plurality of connection plug rods, a plurality of connection plug holes and a plurality of support springs 18;

[0076] Multiple connecting rods are respectively arranged at the bottom of the two second brackets 3 and are slidably connected to the top of the first bracket 2; multiple connecting holes are opened at the top of the first bracket 2 and are adapted to the connecting rods; multiple supporting springs 18 are respectively arranged between the top of the first bracket 2 and the bottom of the second bracket 3, and are respectively sleeved on the outside of the multiple connecting rods.

[0077] When the connecting rod 7 and the vibration block 8 rotate, the second bracket 3 and the vibration roller 6 can vibrate vertically relative to the first bracket 2 through the cooperation of the connecting rod, the connecting hole and the supporting spring 18.

[0078] Reference Figure 8 and Fig. 9 A support ring 71 is provided on the inner side wall of the dynamic pressure roller and is sleeved on the outer side of the connecting rod 7. The support ring 71 is slidably connected to the inner side wall of the vibration pressure roller 6. A guide slide is provided on the inner side wall of the vibration pressure roller 6. A guide slide hole is provided on the outer side wall of the support ring 71 and is slidably connected to the guide slide.

[0079] The support ring 71 can cooperate with the vibrating roller 6 to provide auxiliary support to the connecting rod 7, thereby avoiding affecting the firmness of the connecting rod 7 and preventing the connecting rod 7 from being easily deformed.

[0080] Reference Figure 8 and Fig. 9 A plurality of support ring plates 72 are provided between the inner wall and the outer wall of the vibration roller 6 , and a plurality of water penetration holes 73 are provided on the support ring plates 72 .

[0081] The support ring plate 72 can be used to enhance the firmness of the vibration roller 6, better ensure the vibration rolling effect on the rubber, and prevent the vibration roller 6 from being easily deformed; through multiple perforations, the cooling water can flow smoothly through the support ring plate 72, avoiding affecting the circulation and mixing effect of the cooling water.

[0082] The working principle of the present application is as follows: the user can first add sufficient cooling water into the cooling chamber 9 to cool the vibration roller 6, so that the vibration roller 6 is ready to cool the rubber, and the vibration roller 6, the first roller 4 and the second roller 5 are rotated, and the connecting rod 7 and the vibration block 8 are rotated, so that the two second brackets 3 and the vibration roller 6 are vertically vibrated;

[0083] After that, the rubber material that needs to be calendered after kneading can be placed on the feed plate 14, and the rubber material will then enter between the vibrating roller 6 and the first roller 4. The vibrating roller 6 will cooperate with the rotating first roller 4 during the rotation process to perform preliminary calendering on the rubber material. In the process of vertical vibration, the vibrating roller 6 can also cooperate with the rotating first roller 4 to perform high-frequency extrusion on the rubber material running above the first roller 4, thereby quickly and thoroughly expelling the residual gas in the rubber, so that the user only needs to put the rubber into the calendering device once to quickly and thoroughly expel the residual gas in the rubber.

[0084] The vibrating roller 6 can also cool down the rubber material to prevent the rubber material from easily adhering to the vibrating roller 6, the first roller 4 and the second roller 5 during the calendering process, and can reduce the firmness of the rubber residue adhering to the vibrating roller 6, the first roller 4 and the second roller 5.

[0085] During the rotation and vibration operation, the vibrating roller 6 can also shake and mix the cooling water in the cooling chamber 9, so that the temperature of the cooling water remains balanced, so that the direct cooling effect of the cooling water on the vibrating roller 6 and the indirect cooling effect on the rubber can be fully exerted.

[0086] After the rubber material is calendered by the vibrating roller 6 and the first roller 4, it smoothly enters between the first roller 4 and the second roller 5 for further calendering through the auxiliary traction of the rotating mounting plate 15 and the feed auxiliary push plate 17. The rubber material that has completed the calendering process will be discharged from the second roller 5; after a period of time, the cooling water in the cooling chamber 9 is replaced so that the vibrating roller 6 can restore the cooling effect on the rubber.

[0087] In a second aspect, the present application provides a rubber film calendering method, using the rubber film calendering device of the first aspect, comprising the following steps:

[0088] S1, adding sufficient cooling water into the cooling chamber 9 to cool the vibrating roller 6;

[0089] S2, putting the rubber material onto the feed plate 14, and then making it enter between the vibrating roller 6 and the first roller 4. The rotating vibrating roller 6 cooperates with the first roller 4 to perform preliminary calendering treatment on the rubber material, and can also vibrate under the drive of the connecting rod 7 and the vibration block 8, so as to cooperate with the first roller 4 to perform high-frequency extrusion treatment on the rubber material, so as to quickly and thoroughly discharge the residual gas inside the rubber, and the vibrating roller 6 can cool down the rubber material to prevent the rubber material from adhering to the vibrating roller 6, the first roller 4 and the second roller 5. The vibrating roller 6 can also shake and mix the cooling water in the cooling chamber 9 during the rotating and vibrating operation, so that the cooling effect of the cooling water can be fully exerted;

[0090] S3, after the rubber material is calendered by the vibrating roller 6 and the first roller 4, it can smoothly enter between the first roller 4 and the second roller 5 for further calendering under the auxiliary traction of the rotating mounting plate 15 and the feed auxiliary push plate 17, and the rubber material that has completed the calendering treatment will be discharged from the second roller 5; after a period of time, the cooling water in the cooling chamber 9 is replaced.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
