Description

Technical Field

[0001] This utility model relates to the field of rubber product technology, and in particular to a rubber product calendering and molding device. Background Technology

[0002] Rubber products refer to the activities of producing various rubber products using natural and synthetic rubber as raw materials. It also includes rubber products produced by recycling waste rubber. Calendering is one of the basic processes in rubber product manufacturing. It refers to using a rubber calender and its auxiliary facilities to roll rubber material into sheets of a certain size or shape under the extrusion and shearing action of rollers.

[0003] However, in the existing technology, a heating device is set up to soften the rubber for calendering. However, the heating device is set up externally, which not only poses safety hazards but also results in large heat loss and energy consumption. Furthermore, after the rubber is heated and softened, it is easy to attract and stick dust and debris, which affects the quality of the product. Therefore, we propose a rubber product calendering device. Utility Model Content

[0010] The beneficial effects of this utility model are:

[0011] 1. By setting up a work box and placing the electric heating wire inside, heat loss and energy consumption can be reduced. At the same time, a protective frame is set up to protect the electric heating wire and prevent the rubber material from directly contacting the electric heating wire and melting. The work box can also effectively reduce the contact between dust and debris and rubber products, thus improving product quality.

[0012] 2. By setting up an exhaust fan in conjunction with a collection tank, dust and debris on the surface of the rubber material are cleaned before it enters the work box. The dust and debris on the surface of the rubber material are collected using a filter box and a filter plate, which can effectively reduce the amount of debris and dust on the surface of the rubber material and improve the production quality of rubber products.

It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0023] like Figure 1-5 As shown, this utility model discloses a rubber product calendering and molding device, including a working box 1. A feed inlet 2 is provided on one side of the working box 1. Collection troughs 3 are fixedly installed on the outer wall of the working box 1 above and below the feed inlet 2, respectively. The collection troughs 3 are connected to a collection and filtering mechanism. A lower forming roller 4 is installed at the lower part of the working box 1 via a drive mechanism. A movable frame 5 is installed at the upper part of the working box 1 via a lifting control mechanism. An upper forming roller 6 is horizontally rotatably installed on the inner wall of the movable frame 5. Protective frames 7 are fixedly installed on the movable frame 5 and the inner wall of the working box 1, respectively. An electric heating wire 8 is fixedly installed inside the protective frame 7. The protective frame 7 is used for... The heating wire 8 is wrapped and protected to prevent the rubber from directly contacting the heating wire 8 and melting. The heating wire 8 is used to increase the temperature inside the working box 1 to heat and bake the rubber, making it soft and easier to calender. This device sets up the working box 1 to calender the rubber material inside the working box 1, reducing the impact of dust and debris on the rubber material. At the same time, the heating wire 8 is used to heat and soften the rubber, which is more conducive to the calendering process. Meanwhile, the exhaust fan 11 is set up in conjunction with the collection tank 3 to clean the surface of the rubber, remove the dust and debris, and improve the calendering quality.

[0024] Specifically, the collection and filtration mechanism includes a filter box 9 fixedly installed on the upper wall of the work box 1. A filter plate 10 is vertically fixedly installed inside the filter box 9. An exhaust fan 11 is fixedly installed on the upper wall of the work box 1. The exhaust fan 11 is fixedly connected to the filter box 9 through a connecting pipe 12. The filter box 9 is fixedly connected to two collection tanks 3 through a conduit 13. The exhaust fan 11 provides power and uses the collection tanks 3 to draw and clean the dust and debris on the rubber surface, ensuring the cleanliness of the rubber surface and improving the calendering quality.

[0025] More specifically, the drive mechanism includes a motor 14 that is horizontally fixedly installed on the outer wall of the work box 1. The output shaft of the motor 14 is fixedly connected to the lower forming roller 4. The lower forming roller 4 is rotatably connected to the inner wall of the work box 1. The motor 14 drives the lower forming roller 4 to rotate, which, together with the upper forming roller 6, squeezes and pulls the rubber.

[0026] Furthermore, the lifting control mechanism includes an electric push rod 15 that is vertically fixedly installed on the upper wall of the work box 1. The free end of the electric push rod 15 moves through the work box 1 and is fixedly connected to the moving frame 5. The electric push rod 15 can indirectly adjust the height of the upper forming roller 6 and adjust the distance between the upper forming roller 6 and the lower forming roller 4 to adapt to rubber materials of different thicknesses.

[0027] Furthermore, a discharge port is provided on one side of the work box 1, and sealing pads 16 are fixedly installed on the outer wall of the work box 1 above and below the discharge port. The sealing pads 16 are used to elastically seal the discharge port to prevent external dust from entering the work box 1.

[0028] Working principle:

[0029] Before the rubber enters the working box 1, the exhaust fan 11 draws air through the collection tank 3 to remove dust and debris from the rubber surface. The dust and debris are then sent to the filter box 9 for filtration by the filter plate 10. After that, the rubber material enters the working box 1 and is softened by heating with the electric heating wire 8. The electric heating wire 8 is placed inside the working box 1 to reduce heat loss and save energy. Then, it is calendered between the upper forming roller 6 and the lower forming roller 5. The upper forming roller 6 is mounted on the moving frame 5, and its height can be adjusted by the electric push rod 15 to adjust the distance between the upper forming roller 6 and the lower forming roller 5. This allows for the adaptation of rubber materials of different thicknesses and facilitates the calendering of the rubber to different thicknesses. Finally, the rubber is discharged from the outlet of the working box 1, completing the processing of the rubber material.
