Description

A rubber sheet and fabric pressing equipment Technical Field

[0001] This utility model relates to the field of rubber sheet production technology, specifically to a rubber sheet and fabric pressing equipment. Background Technology

[0002] Rubber sheet lamination with fabric is a common industrial processing technology that combines the properties of rubber with the performance of fabric to create composite materials with specific functions and uses. During the lamination process, rubber molecules and fabric fibers permeate and bond tightly together, resulting in products that combine the flexibility, abrasion resistance, and waterproofness of rubber with the strength and breathability of fabric. This process is widely used in many fields such as automobiles, construction, and clothing.

[0003] Currently, during the pressing process of rubber sheets and fabrics, wrinkles on the rubber sheets and fabrics prevent them from fully adhering, making the pressed sheets prone to delamination and separation during use, reducing their service life, and also reducing the flatness of the pressed sheet surface, thus lowering the appearance quality. To address this, we propose a rubber sheet and fabric pressing equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a rubber sheet and fabric pressing device that can flatten the rubber sheet and fabric before pressing, eliminating wrinkles on the rubber sheet and fabric, so that the rubber sheet and fabric can be fully bonded during pressing, improving the bonding force between the rubber sheet and fabric, preventing separation of the rubber sheet and fabric, thereby extending the service life. At the same time, it also improves the flatness of the surface of the pressed sheet and improves the appearance quality. This invention solves the problem that wrinkles on the rubber sheet and fabric during the current pressing process can prevent them from fully bonding, making the pressed sheet prone to delamination and separation during use, reducing the service life, and also reducing the flatness of the pressed sheet surface, thus reducing the appearance quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rubber sheet and fabric pressing device, comprising a fixed frame and pressing rollers, wherein two pressing rollers are rotatably installed from top to bottom on one side of the outer surface of the fixed frame, and two upper flattening rollers and two lower flattening rollers are rotatably installed from top to bottom on the side of the outer surface of the fixed frame away from the pressing rollers, near the upper and lower surfaces respectively, and the outer surfaces of the two upper flattening rollers and the two lower flattening rollers are symmetrically provided with spiral patterns.

[0006] Preferably, guide rollers are rotatably installed inside the fixed frame near the two pressing rollers, which guides the flattened rubber sheet and fabric, allowing them to better enter between the two pressing rollers.

[0007] Preferably, a pressing motor is fixedly installed on the rear surface of the fixed frame near the pressing roller, and the end of the output shaft of the pressing motor is connected to the end of one of the pressing rollers near the rear surface of the fixed frame, so that the pressing motor drives one of the pressing rollers to rotate.

[0008] Preferably, a first transmission gear is fixedly installed at one end of each of the two pressing rollers near the front surface of the fixed frame, and the two first transmission gears mesh with each other, and the two pressing rollers are driven by the meshing first transmission gears.

[0009] Preferably, a motor frame is fixedly installed on the rear surface of the fixed frame near the lower flattening roller, and a flattening motor is fixedly installed on the rear surface of the motor frame. The end of the output shaft of the flattening motor is connected to the end of one of the lower flattening rollers near the rear surface of the fixed frame. A third transmission gear is fixedly installed on the end of one of the upper flattening rollers and one of the lower flattening rollers near the rear surface of the fixed frame, and the two third transmission gears mesh with each other. The flattening motor drives one of the upper flattening rollers and one of the lower flattening rollers to rotate through the two third transmission gears.

[0010] Preferably, a second transmission gear is fixedly installed at one end of each of the two upper flattening rollers and the two lower flattening rollers near the front surface of the fixed frame. The two upper flattening rollers and the two lower flattening rollers are driven by the two second transmission gears, so that the two upper flattening rollers and the two lower flattening rollers rotate synchronously.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a fixed frame, pressing rollers, upper flattening rollers, lower flattening rollers, and spiral patterns, achieves the ability to flatten rubber sheets and fabrics before pressing, eliminating wrinkles on the rubber sheets and fabrics, so that the rubber sheets and fabrics can be fully adhered during pressing, improving the bonding force between the rubber sheets and fabrics, preventing separation of the rubber sheets and fabrics, thereby extending the service life. At the same time, it also improves the flatness of the sheet surface after pressing, improving the appearance quality. The fabric passes between the two upper flattening rollers, and the rubber sheet passes between the two lower flattening rollers. The symmetrical spiral patterns on the upper and lower flattening rollers cause the rubber sheet and fabric to unfold to the front and back sides, eliminating wrinkles on the rubber sheets and fabrics. The wrinkle-free rubber sheets and fabrics then pass between the two pressing rollers and are pressed together.

[0013] 2. By setting a second transmission gear and a third transmission gear, this utility model achieves the effect of simultaneously driving the upper and lower flattening rollers to rotate using a flattening motor. The flattening motor drives one upper flattening roller and one lower flattening roller to rotate through two third transmission gears, and the two upper flattening rollers and the two lower flattening rollers are all connected by two second transmission gears, so the two upper flattening rollers and the two lower flattening rollers rotate synchronously.

[0014] 3. By setting guide rollers, this utility model guides the flattened rubber sheet and fabric, allowing them to better enter between the two pressing rollers. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] As shown in Figures 1-4, the present invention proposes a rubber sheet and fabric pressing device, which includes a fixed frame 1 and pressing rollers 5. Two pressing rollers 5 are rotatably installed from top to bottom on one side of the outer surface of the fixed frame 1. A pressing motor 12 is fixedly installed on the rear surface of the fixed frame 1 near the pressing rollers 5. The end of the output shaft of the pressing motor 12 is connected to the end of one of the pressing rollers 5 near the rear surface of the fixed frame 1. A first transmission gear 6 is fixedly installed on the end of each of the two pressing rollers 5 near the front surface of the fixed frame 1. The two first transmission gears 6 mesh with each other. The pressing motor 12 drives one of the pressing rollers 5 to rotate, and the two pressing rollers 5 are driven by the meshing first transmission gears 6.

[0022] Two upper flattening rollers 3 and lower flattening rollers 8 are rotatably mounted from top to bottom on the side of the outer surface of the fixed frame 1 away from the pressing roller 5, near the upper and lower surfaces respectively. The outer surfaces of the two upper flattening rollers 3 and the two lower flattening rollers 8 are symmetrically provided with spiral patterns 2. The fabric passes between the two upper flattening rollers 3 and the rubber sheet passes between the two lower flattening rollers 8. The symmetrical spiral patterns 2 on the upper flattening rollers 3 and the lower flattening rollers 8 will cause the rubber sheet and the fabric to unfold to the front and back sides, so as to eliminate wrinkles on the rubber sheet and the fabric.

[0023] A motor frame 11 is fixedly installed on the rear surface of the fixed frame 1 near the lower flattening roller 8. A flattening motor 9 is fixedly installed on the rear surface of the motor frame 11. The end of the output shaft of the flattening motor 9 is connected to the end of one of the lower flattening rollers 8 near the rear surface of the fixed frame 1. A third transmission gear 10 is fixedly installed on the end of one of the upper flattening rollers 3 and one of the lower flattening rollers 8 near the rear surface of the fixed frame 1, and the two third transmission gears 10 mesh with each other. A second transmission gear is fixedly installed on the end of each of the two upper flattening rollers 3 and the two lower flattening rollers 8 near the front surface of the fixed frame 1. Gear 7 and flattening motor 9 drive one upper flattening roller 3 and one lower flattening roller 8 to rotate through two third transmission gears 10. The two upper flattening rollers 3 and the two lower flattening rollers 8 are all driven by two second transmission gears 7, so the two upper flattening rollers 3 and the two lower flattening rollers 8 rotate synchronously. Inside the fixed frame 1, guide rollers 4 are rotatably installed near the two pressing rollers 5. The two guide rollers 4 guide the flattened rubber sheet and fabric, so that the rubber sheet and fabric can enter the space between the two pressing rollers 5 better.

[0024] In use, the fabric passes between two upper flattening rollers 3, and the rubber sheet passes between two lower flattening rollers 8. The symmetrical spiral patterns 2 on the upper and lower flattening rollers 3 and 8 cause the rubber sheet and fabric to unfold to the front and back sides, eliminating wrinkles on the rubber sheet and fabric. The wrinkle-free rubber sheet and fabric then pass between two pressing rollers 5 and are pressed together, ensuring sufficient adhesion between the rubber sheet and fabric during pressing. This improves the bonding force between the rubber sheet and fabric, prevents separation of the rubber sheet and fabric, extends the service life, and also improves the flatness of the sheet surface after pressing, thus improving the appearance quality.

[0025] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
