Description

A double-cone three-roll precision calender sheet extrusion machine Technical Field

[0001] This utility model relates to the technical field of rubber processing equipment, and specifically to a double-cone three-roll precision calendering sheet extruder. Background Technology

[0002] Rubber calendering and sheeting machines are key pieces of equipment in rubber processing that affect product quality. After extrusion, the rubber needs to be sheeted in the next process. Currently, most rubber extrusion and sheeting equipment on the market are separate units. Some integrated units only have double-roll calendering and lack the functions of repeated material reprocessing and edge trimming. If repeated calendering is needed to improve the sheeting quality, manual switching between processes is required, which is not only inefficient but also increases equipment and labor costs. It also easily leads to material leakage and waste, and high maintenance costs. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a double-cone three-roll precision calendering sheet extrusion machine. By integrating the feeding extrusion equipment and the rubber sheeting equipment into a single structure and adding a return feeding function, the rubber material is forced to be fed through the double cones and pressed into sheets. After repeated calendering by the three rolls, the rubber sheet is finally processed by the edge trimming function. This improves overall work efficiency and the quality of the rubber sheet extrusion while reducing production costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A double-cone three-roll precision calendering sheet machine includes a machine base, a rolling mechanism, a feeding mechanism, an electrical distribution box, a control box, a water circulation mechanism, and a return glue conveying mechanism. The rolling mechanism, feeding mechanism, and electrical distribution box are all mounted on the machine base. A roll base is mounted on the rolling mechanism and fixed to the machine base. A feeding base is mounted on the feeding mechanism and fixed to the machine base. The control box is fixed to the roll base. The water circulation mechanism is fixed to one side of the machine base. A roll motor and two symmetrically arranged roll bearing seats are also mounted on the roll base. An upper roll, a middle roll, and a lower pressure roll are arranged vertically between the two roll bearing seats. A feeding motor is fixed to the side of the feeding base. A feeding hopper is located at the top of the feeding base. The fish-tail feeding port on the feeding hopper corresponds to the center seam on the back of the upper and middle rolls. A discharge hopper is located at the top of the feeding hopper. A first cone rod and a second cone rod are arranged inside the feeding hopper.

[0006] Furthermore, a gearbox is provided between the roll motor and the intermediate roll, and the power output main shaft of the roll motor is meshed with the intermediate roll through the gearbox. The upper roll and the lower pressure roll are meshed with the intermediate roll through the gearbox.

[0007] Furthermore, the upper roll, middle roll, and lower pressure roll are arranged in the same plane and are parallel to each other. An upper roll pitch adjustment motor is installed on the roll bearing seat at the top of the upper roll, and a lower roll pitch adjustment motor is installed on the roll bearing seat at the bottom of the lower pressure roll.

[0008] Furthermore, the front side of the roll bearing housing is also provided with an edge trimming cutter device and a padding roller. The edge trimming cutter device is provided with two sets of cutting blades. The cutting blades on the edge trimming cutter device are fitted together with the padding roller. One end of the padding roller is connected to one end of the intermediate roll through a transmission chain.

[0009] Furthermore, the first cone rod inside the feeding hopper is connected to the power output main shaft of the feeding motor, and the second cone rod is meshed with the first cone rod through a gear. Both the first and second cone rods are provided with helical blades.

[0010] Furthermore, the central shafts of the upper roll, middle roll, and lower pressure roll are respectively connected to the water circulation mechanism via pipes, and the water circulation mechanism is also connected to the feeding hopper via pipes.

The conveyor belt is arranged corresponding to the upper roller, and a conveyor motor is provided on the side of the conveyor belt.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] A double-cone three-roll precision calendering sheet extrusion machine includes a machine base, a rolling mechanism, a feeding mechanism, an electrical distribution box, a control box, a water circulation mechanism, and a return rubber conveying mechanism. The rolling mechanism, feeding mechanism, and electrical distribution box are all mounted on the machine base. A roller base is mounted on the rolling mechanism and fixed to the machine base. A feeding base is mounted on the feeding mechanism and fixed to the machine base. The control box is fixed to the roller base.

On one side, a roll motor 21 and two symmetrically arranged roll bearing seats 22 are also provided on the roll base 20. An upper roll 24, a middle roll 23 and a lower pressure roll 25 are arranged vertically between the two roll bearing seats 22. A feeding motor 31 is fixed on the side of the feeding base 30. A feeding hopper 32 is provided on the upper part of the feeding base 30. The fish tail feeding port on the feeding hopper 32 is arranged corresponding to the middle seam on the back of the upper roll 24 and the middle roll 23. A lower hopper 33 is provided on the upper part of the feeding hopper 32. A first cone rod 34 and a second cone rod 35 are provided inside the feeding hopper 32.

[0020] By fixing both the roller pressing mechanism 2 and the feeding mechanism 3 onto a single base 1, an integrated structure is adopted, which improves the ease of equipment installation and reduces equipment maintenance costs.

[0021] A gearbox is provided between the roll motor 21 and the middle roll 23. The power output shaft of the roll motor 21 is meshed with the middle roll 23 through the gearbox. The upper roll 24 and the lower pressure roll 25 are meshed with the middle roll 23 through the gearbox. The middle roll 23, the upper roll 24 and the lower pressure roll 25 are driven by the roll motor 21. The film is repeatedly calendered by the three rolls to improve the quality of the film.

[0022] The upper roll 24, the middle roll 23, and the lower pressure roll 25 are arranged in the same plane and are parallel to each other. The upper roll 24 is equipped with an upper roll pitch adjustment motor 26 on the roll bearing seat 22 above it, and the lower pressure roll 25 is equipped with a lower roll pitch adjustment motor 27 on the roll bearing seat 22 below it. The upper roll 24 can automatically adjust the distance between itself and the middle roll 23 through the upper roll pitch adjustment motor 26, and the lower pressure roll 25 can automatically adjust the distance between itself and the middle roll 23 through the lower roll pitch adjustment motor 27. By automatically adjusting the distance between the pressure rolls, the production requirements of different specifications of film materials can be met more conveniently.

[0023] The front and side of the roll bearing housing 22 are also provided with an edge trimming cutter device 28 and a padding roller 29. The edge trimming cutter device 28 is provided with two sets of cutting blades. The cutting blades on the edge trimming cutter device 28 are fitted with the padding roller 29.

The padding roller 29 is also connected to the intermediate roll 23 through the transmission chain 290 to ensure continuous output of the film after calendering and prevent jamming.

[0024] The first cone rod 34 inside the feeding hopper 32 is connected to the power output shaft of the feeding motor 31. The second cone rod 35 is meshed with the first cone rod 34 through a gear. Both the first cone rod 34 and the second cone rod 35 are provided with spiral blades. The first cone rod 34 and the second cone rod 35 are forcibly fed by the transmission of the feeding motor 31, so that the rubber material is squeezed out from the fish tail feeding port on the feeding hopper 32 to the roller pressing mechanism 2 for pressing.

[0025] The central shafts of the upper roller 24, the middle roller 23, and the lower pressure roller 25 are connected to the water circulation mechanism 6 through pipes. The water circulation mechanism 6 is also connected to the feeding hopper 32 through pipes. The water circulation mechanism 6 can cool down the feeding rod and the pressure roller to prevent the cone rod and roller shaft from heating up during operation, which would cause the rubber material to stick.

[0026] The return conveying mechanism 7 is fixed on the upper part of the roller bearing seat 22. The return conveying mechanism 7 is equipped with a conveyor belt 70, which is correspondingly arranged with the upper roller 24. A conveyor motor 71 is arranged on the side of the conveyor belt 70. The return conveying mechanism 7 can return the edge material cut by the cutter device 28 to the feeding hopper 32 for repeated feeding and calendering, to prevent waste of residual material and save manpower for collection.

[0027] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
