Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of goods conveyer technical field, specifically to a kind of modularization conveying belt. BACKGROUND

[0002] Modularization belt is widely used in goods conveyer field, usually used to convey discrete products or workpieces in production environment, these modularization belt units are generally manufactured by injection molding from plastic material, modularization belt units are continuously arranged in perpendicular to conveying direction, and positioned with adjacent module in conveying direction and connected by pin shaft rotation.

[0003] For the mesh belt conveyor applied to automobile manufacturing plant, it can be required to drive 30-40 vehicles or vehicle bodies to be assembled simultaneously, and about 2-3 workers per station, to continuously run at a speed of about 3-8 meters / minute, wherein typically, a vehicle assembly workshop completion line with 60JPH of a beat, the station length is 6 meters, and the running speed is 6 meters / minute, the workers complete liquid filling such as fuel, brake fluid and cooling fluid on the mesh belt conveyor, and preliminarily inspect and adjust the vehicle body assembly. The modularization mesh belt constitutes the upper surface of the mesh belt conveyor, drives the vehicle / vehicle body which keeps relatively stationary with the mesh belt, and the worker walking on the mesh belt runs to the driving end, and the high molecular weight polyethylene plate or stainless steel plate is generally fixedly arranged below the modularization mesh belt as a support plate, and relative sliding occurs between the modularization mesh belt and the support plate during running.

[0004] The weight of a single vehicle produced by the automobile manufacturing plant can be greater than 2000KG, but for plug-in hybrid and extended range vehicles which are hot-selling in China in recent years, due to the configuration of large battery and fuel engine / transmission in the vehicle, the weight of a single vehicle can reach 3000KG or higher. In order to effectively reduce the frictional resistance between the modularization mesh belt and the support plate during running to the driving end, and the tension borne by the corresponding mesh belt, and reduce the energy consumption of the driving mechanism, the sliding friction coefficient between the modularization mesh belt and the support plate arranged below it needs to be low. On the contrary, since the vehicle or vehicle body needs to keep relatively stationary with the modularization mesh belt, the corresponding assembly, inspection and adjustment are completed by the walking worker, which determines that the modularization mesh belt has a large static friction coefficient with the tire (rubber material) of the vehicle and the snowmobile base (usually square steel pipe) for fixing the vehicle body, and has a large sliding friction coefficient with the safety shoes of the walking worker, which needs to reach the anti-slip level of R10 or higher known by the employees.

[0005] The prior art net belt modular unit made of a single plastic material by an injection molding process uses a material usually POM, PA, PP base material, which cannot achieve the required low friction coefficient between the support plate and the required higher friction coefficient between the bearing and the directly contacted automobile tire / sled base of the bearing vehicle body. This situation greatly limits the application of the maintenance-free, low-noise net belt conveyor in the automobile production factory. Under certain working conditions, the automobile production factory has to be forced to use the old steel chain conveyor which is noisy, needs frequent lubrication and maintenance, and needs a deep foundation or pit.

[0009] Further, the top surface of the antifriction longitudinal connecting piece is lower than the upper surface of the modular belt unit body, so as to make the antifriction longitudinal connecting piece not in contact with the workpiece being conveyed.

[0010] Further, the lower surface of the modular belt unit body is provided with a reinforcing strip.

[0011] Further, the upper surface of the modular belt unit body is distributed with anti-skid protrusions.

Front pins 4 and rear pins 5 are respectively inserted into the front lugs 2 and rear lugs 3. The lower surface of the modular belt unit body 1 is provided with a through groove 6. A friction-reducing longitudinal connector 7 is provided in the through groove 6. The friction-reducing longitudinal connector 7 includes a connecting piece A12 and a connecting piece B13. The connecting pieces A12 and B13 are bent non-flat structures. The corresponding front holes 8 and corresponding rear holes 9 on the connecting pieces A12 and B13 are respectively inserted into the front pins 4 and rear pins 5. One end of the connecting piece A12 and one end of the connecting piece B13 are tightly attached together, and the other ends of the connecting pieces A12 and B13 are outwardly flared. A fastener 14 is provided between connecting piece A12 and connecting piece B13.

The upper end of the fastener 14 is provided with a locking head 17, which is locked onto the upper side of connecting piece A12 and connecting piece B13 to secure connecting piece A12 and connecting piece B13 to the modular belt unit body 1.

[0032] The bottom surface of the friction-reducing longitudinal connector 7 protrudes from the lower surface of the modular belt unit body 1, so that the friction-reducing longitudinal connector 7 can directly contact the support plate below, while preventing the modular belt unit body 1 from contacting the support plate below.

[0037] Working Principle: This application adds a friction-reducing longitudinal connector to the modular belt unit body. The bottom surface of the friction-reducing longitudinal connector protrudes from the lower surface of the modular belt unit body, allowing it to directly contact the lower support plate while preventing direct contact between the modular belt unit body and the lower support plate. In other words, by installing the friction-reducing longitudinal connector with a low coefficient of friction and good wear resistance onto the front and rear pins of the modular belt unit body, and ensuring direct contact between the connector and the lower support plate, the required low coefficient of sliding friction is achieved. Furthermore, when using a high-strength friction-reducing material to manufacture the longitudinal connector, it can significantly improve the tensile strength of the modular conveyor belt. The modular belt unit body is made of a high-friction-coefficient engineering plastic, which is generally less expensive than low-friction-coefficient engineering plastics. This results in a higher coefficient of static or sliding friction between the connector and the car tires / body skids above the conveyor belt, as well as between the workers and the material.
