Description

Technical Field

[0001] The utility model relates to the technical field of mixer rubber production, and specifically provides a rubber feeding device for mixer rubber production. Background Art

[0002] The rubber compound obtained by mixing raw rubber or plasticated rubber with compounding agents according to a formula through a rubber mill is called mixer rubber. Mixer rubber is the blank, i.e., semi-finished product, for manufacturing rubber products. Therefore, the colloidal dispersion quality of mixer rubber is directly related to the quality of the finished product. At the same time, the viscoelasticity and rheology of mixer rubber directly affect the processing performance of the rubber compound during operation and the processing technologies such as molding, extrusion, calendering, and extrusion in later production. After the mixer rubber is processed into rubber blocks, feeding is required. During the feeding process, since the surface of the colloid is not flat, it will to a certain extent affect the subsequent processing process, increase the processing difficulty, reduce the quality of the produced products, and impurities are likely to remain on the surface of the mixer rubber blocks. Therefore, cleaning the mixer rubber blocks during the feeding process is also a very important step.

[0003] For example, a rubber feeding device for mixer rubber production disclosed in the patent document with the application number 202322981955.7 has a structure including a driving rod with a limiting member engaged on one side. The beneficial effects of the present utility model are as follows: The touch block provided on the limiting member above the roller. When the roller rotates, the colloid will touch the arc surface of the touch block to produce curling, so that the colloid can be better mixed during pressing. After the pressing process is completed, the pneumatic rod is driven by the electric cylinder to push the movable plate forward, so that the cutter head on the fixed block cuts the colloid. Through the rotating roller, the colloid will slowly be removed from the roller and fall into the material receiving tray. Because the fixed block will deform when contacting the roller, the adhesion strip in the concave part will contact the roller, thereby further adhering the colloid remaining on the roller. In summary, the mixing efficiency of the colloid during rubber mixing on the open mill is improved, and the colloid can be cut and removed by the cutter head on the movable plate, improving the convenience during unloading.

[0004] The rubber feeding device for mixer rubber production disclosed in the above document improves the mixing efficiency of the colloid during rubber mixing on the open mill through the setting of the touch block and other components, and at the same time improves the convenience during unloading. However, it does not perform certain pre-treatment on the rubber blocks to be processed, such as leveling and cleaning the surface of the rubber blocks, making it more convenient for processing and improving the processing efficiency.

[0005] It can be seen from this that the existing rubber feeding devices for mixer rubber production do not have the function of leveling rubber blocks, and it is necessary to improve the existing deficiencies to provide a function that can level rubber blocks. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a rubber feeding device for mixer rubber production to at least solve to some extent the problems raised in the above background art.

[0007] To solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model relates to a rubber feeding device for the production of mixed rubber, which comprises a conveying component and a leveling component. The conveying component comprises a mounting plate, a protective cover is installed above the mounting plate, and the leveling component is arranged inside the protective cover. The leveling component comprises a first electric telescopic rod, the first electric telescopic rod is installed at the top of the protective cover through a second bracket, a upper pressing plate is installed at the telescopic end of the first electric telescopic rod, an upper heating plate is arranged on the bottom surface of the upper pressing plate, second electric telescopic rods are assembled on the inner side surfaces of the protective cover, side pressing plates are connected to the telescopic ends of the two second electric telescopic rods, and side heating plates are arranged on the surfaces of the two side pressing plates away from the second electric telescopic rods.

[0009] Further, a driving roller and a driven roller are movably connected between the two mounting plates. The driving roller and the driven roller are respectively installed at the two ends of the mounting plate. One end of the driving roller is connected to the output end of a first motor. The first motor is installed on the side surface of the mounting plate through a first bracket. The driving roller and the driven roller are surrounded by a belt.

[0010] Further, two mounting seats are fixedly installed at one end of the upper pressing plate, and guide holes are respectively opened in the middle parts of the two mounting seats.

[0011] Further, the leveling component comprises a brush. The two ends of the brush are movably installed between the two through the guide holes in the middle parts of the two mounting seats, and one end of the brush extends through the guide hole to the outside of the protective cover.

[0012] Further, a movable groove is opened on the outer surface of the protective cover. One end of the brush is connected to a second motor through the movable groove. A slider is fixedly installed at the bottom of the second motor, and the slider is movably installed in the movable groove.

[0013] Further, a rubber blocking plate is arranged at the other end of the upper pressing plate.

[0014] The utility model has the following beneficial effects:

[0015] Through the settings of the upper pressing plate, side pressing plate, rubber blocking plate, heating plate and brush, after the machine is started and before leveling, when the rubber block moves from the feeding end to the discharging end, the upper pressing plate first moves downward driven by the first electric telescopic rod. After reaching a suitable position, the second motor drives the brush to rotate to clean the surface of the rubber block, avoiding the impurities on the surface of the rubber block from affecting the subsequent processing process. Then, the rubber block moves from the feeding end to the leveling assembly driven by the belt. After entering the protective cover, the rubber block is first blocked by the rubber blocking plate and stops moving forward. Then, the upper pressing plate presses downward driven by the first electric telescopic rod, and at the same time, the side pressing plate also presses the rubber block driven by the second electric telescopic rod. After the limiting is completed, the upper heating plate and the side heating plate assembled on the surfaces of the upper pressing plate and the side pressing plate start to heat up, and the temperature gradually rises, thereby softening the rubber block. After the rubber block is softened, the upper pressing plate and the side pressing plate further press the rubber block driven by the first electric telescopic rod and the second electric telescopic rod, thereby shaping the rubber block, making the surface of the rubber block smoother, making it more convenient in the subsequent processing process, and the quality of the processed product is higher.

[0016] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. Brief Description of the Drawings

[0025] Please refer to Figure 1 - Figure 4 As shown, the present utility model is a rubber supply device for the production of mixed rubber, including a conveying assembly 1 and a flattening assembly 2. The conveying assembly 1 includes a mounting plate 101. A protective cover 107 is installed above the mounting plate 101. The flattening assembly 2 is arranged inside the protective cover 107. The flattening assembly 2 includes a first electric telescopic rod 201. The first electric telescopic rod 201 is installed on the top of the protective cover 107 through a second bracket 202. The telescopic end of the first electric telescopic rod 201 is installed with an upper pressing plate 203. An upper heating plate 204 is arranged on the bottom surface of the upper pressing plate 203. Second electric telescopic rods 205 are assembled on the inner sides of the protective cover 107. The telescopic ends of the two second electric telescopic rods 205 are both connected with side pressing plates 206. Side heating plates 207 are arranged on the surfaces of the two side pressing plates 206 away from the second electric telescopic rods 205. The purpose of such a setting is that after the machine is started, the rubber block moves towards the flattening assembly 2 under the drive of the belt 106 from the feeding end. After entering the protective cover 107, the rubber block is first blocked by the rubber blocking plate 213 and no longer moves forward. Then, the upper pressing plate 203 presses downward under the drive of the first electric telescopic rod 201. At the same time, the side pressing plates 206 also press the rubber block under the drive of the second electric telescopic rods 205. After the limiting is completed, the upper heating plate 204 and the side heating plate 207 assembled on the surfaces of the upper pressing plate 203 and the side pressing plates 206 start to heat up, and the temperature gradually rises, so as to soften the rubber block. After the rubber block is softened, the upper pressing plate 203 and the side pressing plates 206 further press the rubber block under the drive of the first electric telescopic rod 201 and the second electric telescopic rods 205, so as to shape the rubber block, make the surface of the rubber block more flat, make it more convenient in the subsequent processing process, and improve the quality of the processed product.

[0026] There is a driving roller 102 and a driven roller 103 movably connected between two mounting plates 101. The driving roller 102 and the driven roller 103 are respectively installed at both ends of the mounting plate 101. One end of the driving roller 102 is connected to the output end of the first motor 104. The first motor 104 is installed on the side of the mounting plate 101 through the first bracket 105. The driving roller 102 and the driven roller 103 are surrounded by the belt 106. The purpose of such a setting is to convey the rubber block.

[0027] Two mounting seats 208 are fixedly installed at one end of the upper pressing plate 203. Guide holes are provided in the middle of the two mounting seats 208. The purpose of such a setting is to install the brush 209.

[0028] The leveling assembly 2 includes a brush 209. Both ends of the brush 209 are movably installed between the two through the guide holes in the middle of the two mounting seats 208. One end of the brush 209 extends through the guide hole to the outside of the protective cover 107.

[0029] An activity groove 211 is provided on the outer surface of the protective cover 107. One end of the brush is connected to the second motor 210 through the activity groove 211. A slider 212 is fixedly installed at the bottom of the second motor 210. The slider 212 is movably installed in the activity groove 211. The purpose of such a setting is that before leveling, when the rubber block moves from the feeding end to the discharging end, the upper pressing plate 203 first moves downward under the drive of the first electric telescopic rod 201. After reaching a suitable position, the second motor 210 drives the brush 209 to rotate to clean the surface of the rubber block, avoiding the influence of impurities on the surface of the rubber block on the subsequent processing process.

[0030] A rubber blocking plate 213 is provided at the other end of the upper pressing plate 203. The purpose of such a setting is to prevent the rubber block from moving forward during the leveling process.

[0031] During use, after the machine is started, the rubber block moves from the feeding end to the leveling assembly 2 driven by the belt 106. After entering the protective cover 107, the rubber block is first blocked by the rubber blocking plate 213 and stops moving forward. Then, the upper pressing plate 203 moves downward under the drive of the first electric telescopic rod 201. At the same time, the side pressing plate 206 also presses the rubber block under the drive of the second electric telescopic rod 205. After the limiting is completed, the upper heating plate 204 and the side heating plate 207 assembled on the surfaces of the upper pressing plate 203 and the side pressing plate 206 start to heat up, and the temperature gradually rises, thereby softening the rubber block. After the rubber block is softened, the upper pressing plate 203 and the side pressing plate 206 further press the rubber block under the drive of the first electric telescopic rod 201 and the second electric telescopic rod 205, thereby shaping the rubber block, making the surface of the rubber block smoother, making it more convenient in the subsequent processing process, and the quality of the processed product is higher.

[0032] After the leveling is completed, the first electric telescopic rod 201 drives the upper pressing plate 203 to move upward. The side pressing plate 206 also returns to its original position under the drive of the second electric telescopic rod 205. At the same time, the rubber blocking plate 213 also moves upward with the upper pressing plate 203 and gradually moves away from the rubber block. After the rubber block is no longer blocked, it continues to move toward the discharge port under the drive of the belt 106.

[0033] Before leveling, when the rubber block moves from the feeding end to the discharging end, the upper pressing plate 203 first moves downward under the drive of the first electric telescopic rod 201. After reaching the appropriate position, the second motor 210 drives the brush 209 to rotate to clean the surface of the rubber block, avoiding the influence of impurities on the surface of the rubber block on the subsequent processing process.
