Description

Technical Field

[0001] The utility model relates to the technical field of rubber mixing mills, in particular to a double-roller rubber mixing mill. Background Art

[0002] The mixing mill is an early type of plastic mixing equipment used in plastic product manufacturers. On the calender production line, the mixing mill is placed before the calender and after the mixer. Its function is to mix and plasticize the evenly mixed raw materials, and provide a relatively evenly mixed and plasticized molten material for the calender to form plastic products.

[0003] It is inevitable that some rubber will slip off the extrusion rollers during operation of the existing double-roll rubber mixing mill, and the mixed material needs to be manually mixed and turned in a high temperature environment, which consumes a lot of physical energy for workers. In addition, according to the different amounts of rubber put in, the rubber needs to be properly limited so that the rubber can be mixed centrally on the rollers. At present, the above operation method is still mainly completed manually, which is unreasonable and not conducive to promotion and use. Utility Model Content

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A double-roll rubber mixing mill comprises: a body assembly and a material control assembly; the body assembly is provided with an extrusion roller, and the material control assembly is arranged on the body assembly; the material control assembly comprises a driving mechanism connected to the extrusion roller in transmission, a feeding mechanism arranged on the driving mechanism, and a material limiting mechanism arranged in the feeding mechanism; the feeding mechanism comprises a feeding barrel sleeved on the outside of the extrusion roller, a flap arranged on the feeding barrel, a limit strip fixed to the inner side of the feeding barrel and the flap, and side grooves opened on both sides of the feeding barrel.

[0008] In a preferred example, the utility model can be further configured as follows: the material limiting mechanism includes a fixed plate installed on the inner side of the upper barrel, a material limiting plate sleeved on the extrusion roller, a connecting belt connected between the fixed plate and the material limiting plate, and an electric telescopic rod installed on the upper barrel and connected to the material limiting plate.

[0009] In a preferred example, the utility model can be further configured as follows: the driving rollers are arranged on both sides of the lower part of the upper barrel.

[0010] In a preferred example, the present utility model can be further configured as follows: the limiting strip is evenly arranged around the inner side of the feeding cylinder.

[0011] In a preferred example, the present utility model can be further configured as follows: the connecting belt adopts an annular elastic sheet structure.

[0012] The above technical solution of the present utility model has the following beneficial technical effects:

[0013] Through the material control component, the present utility model can drive the driving roller to rotate by means of the transmission belt during operation, and then make the feeding cylinder rotate. When the rubber slides off the extrusion roller, it will fall into the feeding cylinder, and then naturally fall again between the extrusion rollers when rotating to the highest point, so as to realize cyclic feeding without manual assistance. At the same time, the electric telescopic rod can drive the material limiting plate to displace on the extrusion roller, and push the rubber repeatedly towards the middle, which can effectively improve the mixing efficiency of the rubber and realize fully automated operation.

[0021] To make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0022] The following describes a two-roll rubber kneader provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0023] Combined with Figures 1 - 3As shown, the utility model provides a double-roll rubber mill, comprising: a machine body component 100 and a material control component 200; the machine body component 100 is provided with a squeezing roller 110, and the material control component 200 is arranged on the machine body component 100;

[0024] The material control assembly 200 includes a driving mechanism connected to the squeezing roller 110, a feeding mechanism arranged on the driving mechanism, and a limiting mechanism arranged in the feeding mechanism; the feeding mechanism includes a feeding barrel 210 sleeved on the outside of the squeezing roller 110, a flip cover 220 arranged on the feeding barrel 210, a limiting strip 230 fixed to the inner sides of the feeding barrel 210 and the flip cover 220, and side slots 240 opened on both sides of the feeding barrel 210; the limiting mechanism includes a fixed plate 310 installed on the inner side of the feeding barrel 210, a limiting plate 320 sleeved on the squeezing roller 110, and a fixing plate 310 connected to the limiting plate 320. 20 and the electric telescopic rod 340 installed on the feeding barrel 210 and connected to the limiting plate 320, can use the transmission belt 250 to drive the driving roller 260 to rotate during operation through the material control component 200, so that the feeding barrel 210 can rotate. When the rubber slides off the squeezing roller 110, it will fall into the feeding barrel 210, and then naturally fall between the squeezing rollers 110 when it rotates to the highest point. In this way, cyclic feeding is realized without the need for manual assistance. At the same time, the electric telescopic rod 340 can drive the limiting plate 320 to move on the squeezing roller 110, and repeatedly push the rubber to the middle, which can effectively improve the mixing efficiency of the rubber and realize fully automated operation.

[0025] Specifically, the driving mechanism includes a transmission belt 250 connected to the squeezing roller 110 and a driving roller 260 assembled on the body assembly 100 and connected to the transmission belt 250. The driving mechanism can make the driving roller 260 rotate synchronously with the squeezing roller 110, which is more practical.

[0026] Furthermore, the driving rollers 260 are arranged on both sides of the lower part of the upper barrel 210 , and the driving rollers 260 can be used to drive the upper barrel 210 to roll naturally, which is more reasonable.

[0027] On the other hand, the limiting strips 230 are evenly arranged around the inner side of the upper barrel 210 , which can limit the rubber and prevent it from sliding in the upper barrel 210 .

[0028] It should be noted that the connecting belt 330 adopts an annular spring sheet structure, and the connecting belt 330 can be deformed with the displacement of the limiting plate 320, and at the same time play a limiting role on the fallen rubber, guiding it between the squeezing rollers 110, which is more reasonable.

[0029] Working principle and usage process of the present utility model: First, start the device. While the extrusion roller 110 rotates, the feeding cylinder 210 on the driving roller 260 is driven to rotate through the transmission belt 250. When the rubber slides off the extrusion roller 110, it will fall into the feeding cylinder 210, and then when it rotates to the highest point, it will naturally fall again between the extrusion rollers 110, thus realizing cyclic feeding. At the same time, the electric telescopic rod 340 can drive the material limiting plate 320 to displace on the extrusion roller 110, pushing the rubber repeatedly towards the middle to accelerate the mixing efficiency.

[0030] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
