Description

Technical Field

[0001] The utility model relates to the technical field of rubber piece production, in particular to a calendering device for a rubber piece production extruder. Background Art

[0002] The production of rubber parts is a complex process involving multiple techniques and technologies. It is mainly used to manufacture rubber parts in various industries and daily necessities. It usually includes key steps such as batching, rubber mixing, molding and vulcanization. During the molding process, extruders and calenders are required to cooperate with rubber to mold, so as to produce rubber parts of different thicknesses that meet the specifications.

[0003] In the prior art, after the rubber is extruded by a rubber extruder, the rubber is directly transported to a calender for calendering. Common calenders in the prior art include three-roller type and four-roller type. However, after the rubber is extruded through the three-roller or four-roller calender, due to the high ductility of the rubber, the two sides of the calendered rubber belt will present irregular curvatures. These irregular curvatures will affect the production quality. Therefore, it is necessary to perform trimming on both sides of the rubber belt to ensure that both sides are in a flat state. The cutting of the rubber belts on both sides is usually done manually, which not only cannot ensure whether the cutting angle is flat, but also has the problem of low efficiency.

[0026] like Figures 1 to 6 As shown, a rubber part production extruder calendering device comprises a three-roll calender body 1 and an operating table 2, wherein the operating table 2 is fixedly mounted on one side of the three-roll calender body 1, and mounting plates 4 are fixedly mounted on both sides of the operating table 2, wherein a rotating hole is opened on one side of one of the mounting plates 4, and a cutting mechanism is rotatably mounted in the rotating hole;

[0027] The cutting mechanism includes a cutting roller 16, which is rotatably installed in the rotating hole. A cutting groove is provided on the upper side of the operating table 2. The same bellows 8 is fixedly installed on the opposite surfaces of the two mounting plates 4. A connecting hole is provided on one side of the two mounting plates 4. The same driving rod 9 is rotatably installed in the two connecting holes.

[0028] By means of the above structure, the size of the driving gear 14 is much smaller than the transmission gear 15, ensuring that the rotation rate of the driving gear 14 is lower than the rotation rate of the transmission gear 15, preventing the cutting roller 16 from rotating at too high a speed, causing additional friction loss during the cutting process. The three-roll calender body 1 is a prior art, which is composed of three calendering rollers. When in use, the raw material is put in through the calendering rollers located between the first and second calendering rollers on the upper side, and passes through the second and third rollers, and then is discharged from the three-roll bending at the bottom to complete the calendering. The operating table 2 is installed at the discharge port, and two cutting blades are installed on the surface of the cutting roller 16. Two matching cutting grooves are provided on the operating table 2, which can be used in combination to cut the rubber belt.

[0029] Furthermore, the separation component includes two limit plates 20, which are respectively fixedly installed on both sides of the operating table 2. A sliding opening is opened on the upper side of the two limit plates 20, and a reciprocating block 21 is slidably installed in the sliding opening.

[0038] By means of the above structure, by rotating the threaded rod 7, the threaded rod 7 drives the lifting block 6 to move, and the lifting block 6 drives the secondary guide roller 5 to move downward, so that the secondary guide roller 5 drives the rubber belt to gradually fit on the operating table 2, which is convenient for guiding the rubber belt and making it tight and fit on the operating table 2.

[0039] Working principle: When the device is in use, first start the three-roll calender body 1 and put the rubber raw material extruded by the extruder between the first and second calender rollers on the top. The rubber raw material is first calendered by the first and second calender rollers, and then calendered by the second and third calender rollers, and then discharged from the lower side of the third calender roller. The rubber belt after calendering first sticks its lower side to the surface of the first-level guide roller 3, and then guides its upper side to stick to the surface of the second-level guide roller 5 and pass through. At this time, the three-roll calender body 1 is stopped, and then the threaded rod 7 is rotated, and the threaded rod 7 drives the lifting block 6 to move, and the lifting block 6 drives the second-level guide roller 5 moves downward, so that the secondary guide roller 5 drives the rubber belt to gradually fit on the operating table 2, then restart the three-roll calender body 1, manually pull and guide the rubber belt to move toward the direction of the winding roller 31, and start the driving motor 17 at the same time, the output end of the driving motor 17 drives the driving rod 9 to rotate, the driving rod 9 drives the driving gear 14 to rotate, the driving gear 14 drives the transmission gear 15 to rotate, and the transmission gear 15 drives the cutting roller 16 to rotate. When the rubber belt fits and moves to the cutting area of ​​the cutting roller 16, the cutting roller 16 rotates to cut both sides of the rubber belt and remove the irregular edges on both sides.

[0040] When cutting, the driving rod 9 drives multiple primary bevel gears 12 to rotate, and the multiple primary bevel gears 12 drive the corresponding secondary bevel gears 13 to rotate, and the secondary bevel gears 13 drive the rotating shaft to rotate, and the rotating shaft drives the corresponding blades 11 to rotate, so that negative pressure is formed in the bellows 8, and the outside air enters through the air inlet and is discharged through the air outlet, so as to cool the rubber belt and reduce its viscosity.

[0041] At the same time, the transmission gear 15 drives the driving disk 28 to rotate, and the driving disk 28 drives the transmission disk 27 to rotate through the transmission belt 29, and the transmission disk 27 drives the transmission rod 18 to rotate, and the transmission rod 18 drives the two guide sleeves 19 to rotate, and the guide sleeve 19 drives the matching limit block 22 through the reciprocating groove on its surface to reciprocate the reciprocating block 21 limited on the limit plate 20, so that the two reciprocating blocks 21 simultaneously perform relative mirror reciprocating motion, when the reciprocating block 21 gradually moves to the operating table 2, it drives the installation box 23 to move, and the installation box 23 drives the shifting block 24 to move, and the shifting block 24 is attached to the upper side of the operating table 2 and performs a small counterclockwise extrusion rotation, and when the shifting block 24 reaches the maximum position, it starts to move in the opposite direction, at this time, due to the effect of friction, the shifting block 24 rotates clockwise When the pricking foot 25 is separated from the operating table 2, the rubber belt is automatically separated from the pricking foot 25 and is discharged from the operating table 2 by the guide block 30, and the finished rubber belt is continuously guided to the winding roller 31, and the winding roller 31 is started to rotate, and an external force is applied to the finished rubber belt to make it wind up, thereby completing the rolling production of the rubber parts.
