Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, and in particular to an elastic pressure belt structure. Background Technology

[0002] Elastic pressure belts typically consist of two pulleys and a surrounding ring belt. The belt material is often polyurethane or rubber. The elastic pulleys are fixed by connecting beams to form a stable support frame. They are mainly used for dynamically adjusting pressure or adapting to load changes.

[0003] Currently, traditional belt drive devices have the following drawbacks: 1. Rigid contact can easily damage brittle materials; 2. They cannot automatically adjust the clamping force according to the thickness of the material; 3. Insufficient coefficient of friction can cause slippage.

[0004] To address this, an elastic pressure belt structure is proposed, which has the advantages of being suitable for conveying brittle items, automatically adjusting the clamping force, and preventing slippage, thereby solving the problems mentioned in the background technology. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an elastic pressure belt structure, including a bracket, a drive wheel installed at the left end of the bracket surface, and a driven wheel installed at the right side of the bracket surface. A transmission belt is wound around the surfaces of the drive wheel and the driven wheel. A plurality of pressure rollers are equidistantly installed on the bracket surface, and a metal connector is installed at the axle of each pressure roller. A first connecting shaft and a second connecting shaft are connected to the surface of the metal connector, and a spring is hung on the upper end of the metal connector. The spring at the upper end of the metal connector is connected to the bracket surface, and the plurality of pressure rollers are all in rolling connection with the lower surface of the inner side of the transmission belt.

[0007] As a further description of the above technical solution: two guide wheels are mounted on the surface of the bracket, and both guide wheels are in rolling connection with the upper surface of the inner side of the transmission belt, and the two guide wheels are respectively located close to the transmission wheel and the driven wheel.

[0008] As a further description of the above technical solution: the transmission belt is made of a base rubber layer and a surface friction layer by hot pressing, and the top surface of the surface friction layer of the transmission belt is provided with diamond-shaped anti-slip texture. The thickness of the base rubber layer of the transmission belt is 5-8mm, and the thickness of the surface friction layer of the transmission belt is 1-2mm.

[0009] As a further description of the above technical solution: the lower end of the metal connector is provided with a barbed groove, and the second connecting shaft is connected to the inner side of the barbed groove of the metal connector.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] According to an embodiment of the present invention, an elastic pressure belt structure is provided.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3 As shown, an elastic pressure belt structure according to an embodiment of the present invention includes a bracket 1, a drive wheel 2 installed on the left end of the surface of the bracket 1, and a driven wheel 3 installed on the right side of the surface of the bracket 1. A transmission belt 4 is wound around the surfaces of the drive wheel 2 and the driven wheel 3. A plurality of pressure rollers 5 are equidistantly installed on the surface of the bracket 1, and a metal connector 10 is installed at the axle of each pressure roller 5. A first connecting shaft 11 and a second connecting shaft 12 are connected to the surface of the metal connector 10, and a spring 6 is hung on the upper end of the metal connector 10. The spring 6 at the upper end of the metal connector 10 is connected to the surface of the bracket 1. The plurality of pressure rollers 5 are all in rolling connection with the lower surface of the inner side of the transmission belt 4. The transmission belt 4 has a width of 50 mm, a circumference of 2000 mm, and a Shore hardness of 62. The first connecting shaft 11 and the second connecting shaft 12 provide support for the metal connector 10 and facilitate the autonomous tilting of the metal connector 10.

[0023] In one embodiment, two guide wheels are mounted on the surface of the bracket 1, and both guide wheels are in rolling connection with the upper surface of the inner side of the transmission belt 4. The two guide wheels are respectively located close to the transmission wheel and the driven wheel 3. This structure increases the reliability of the installation of the transmission belt 4 and makes it less likely to come loose.

[0024] In one embodiment, the transmission belt 4 is formed by hot pressing a base rubber layer 7 and a surface friction layer 8 together, and the top surface of the surface friction layer 8 of the transmission belt 4 is provided with diamond-shaped anti-slip texture 9. The thickness of the base rubber layer 7 of the transmission belt 4 is 5-8mm, and the thickness of the surface friction layer 8 of the transmission belt 4 is 1-2mm. This structure increases the friction coefficient of the transmission belt 4 and prevents slippage.

[0025] In one embodiment, the lower end of the metal connector 10 is provided with a barbed groove, and the second connecting shaft 12 is connected to the inner side of the barbed groove of the metal connector 10. With this structure, combined with the setting of the spring 6, the metal connector 10 can be automatically tilted, thereby automatically adjusting the clamping force and avoiding damage to the workpiece.

[0026] In one embodiment, multiple sets of pressure rollers 5, metal connectors 10, and springs 6 are provided, and the pressure rollers 5, metal connectors 10, and springs 6 are equidistantly arranged on the bracket 1. This structure forms a pressure roller assembly, achieving the effect of automatically adjusting the clamping force.

[0027] In one embodiment, the portion of the drive belt 4 that contacts the plurality of pressure rollers 5 forms an elastic contact area, and the drive belt 4 is arranged in a flat circular structure. With this structure, it is easy to automatically adjust the clamping force.

[0028] In one embodiment, the pressure roller 5 has a diameter of 80 mm and a 3 mm thick vulcanized rubber coating layer on its surface. This structure increases the contact elasticity between the pressure roller 5 and the transmission belt 4 and enhances the frictional effect of their connection.

[0029] Working principle:

[0030] In operation, the drive belt 4 on the support 1 continuously circulates under the drive of the power wheel 2. When the belt passes the pressure wheel, it is subjected to the elastic force of the spring 6, resulting in a certain degree of elastic deformation. The mechanism can be used to apply downward or side pressure to the workpiece. During operation, the drive belt 4 contacts the workpiece and generates high friction through elastic deformation, thereby clamping or conveying the workpiece. Because the drive belt 4 is elastic, it can adjust the force on the workpiece to a certain extent. When the workpiece is subjected to excessive pressure, the drive belt 4 can absorb some of the pressure through elastic deformation, thus preventing damage to the workpiece.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
